Antecedents and outcomes of teacher leadership: the role of teacher trust, teacher self-efficacy and instructional practice
Authors: Kılınç Ali Çağatay , Bellibaş Mehmet Şükrü , Bektaş Fatih
Published: October 2021

Purpose

Much of the literature on school leadership has concerned itself with the leadership practices of school principals, largely ignoring the leadership capacity of teachers. Much remains unexplored regarding the factors influencing teacher leadership, as well as the impact it has on teaching and learning. Addressing this gap in the literature, this study sought to investigate (1) whether teacher trust influences teacher leadership and (2) whether teacher leadership influences instructional practices directly or indirectly through teacher self-efficacy.

Design/methodology/approach

The study employed a cross-sectional survey design using quantitative methods. A total of 618 teachers participated in the study. By performing structural equation modeling (SEM), we examined the direct and indirect effect of teacher leadership on instructional practice, with self-efficacy as the mediating variable while teacher trust was treated as the antecedent of teacher leadership.

Findings

The results indicated that teacher trust had a direct effect on teacher leadership, and while teacher leadership had no direct effect on instructional practices, an indirect effect was evident through the mediating effect of teacher self-efficacy.

Research limitations/implications

Our findings suggested that teacher leadership is a salient factor that influences teacher instructional practice by enhancing teachers' belief in their capability to cope with problems and improve student learning. Moreover, teacher trust provides intangible support for teachers to engage in leadership work. Since the current study employed a cross-sectional survey rather than a longitudinal one, we cannot accurately establish causal relationships among the study variables.

Originality/value

This study adds nuance to the literature on teacher leadership, where there is still limited international evidence regarding the factors that influence the enactment of teacher leadership, as well as those that mediate its effects on teaching and learning.
Financially distressed suppliers: exit, neglect, voice or loyalty?
Authors: Wagner Stephan M. , Bode Christoph , Peter Moritz A.
Published: October 2021

Purpose

Major crises such as the global financial crisis 2007–08 or the COVID-19 crisis increase the level and likelihood of supplier financial distress. This research expands the understanding of how cooperatively, respectively, uncooperatively buying firms might respond to suppliers who suffer from financial distress in the course of major crises.

Design/methodology/approach

The authors build on a collaborative project with a German automotive OEM, analyze OEM internal “financial quick check data”, questionnaire data and longitudinal supplier financial data and apply regression, mediation and difference-in-difference estimation analyses.

Findings

The results show that the stronger the dependence on the distressed supplier, the more cooperative the buying firm's response. Furthermore, a more cooperative response of the buying firm has a strong positive influence on the suppliers' financial performance and hence recovery from the distress situation. Insights from supplier financial distress in the course of the financial crisis 2007–2008 can serve as learnings for the COVID-19 crisis.

Research limitations/implications

The study fills a gap in the scholarly literature on “response to risk incidents” and response formation. Resource dependence theory and resource dependence dynamics offer a strong rationale for the type of response buying firms are likely to choose.

Practical implications

Besides offering the first menu of response options, this study can help practitioners in figuring out the most appropriate response to distressed suppliers. The findings can assist buying firms in their decisions how to deal with suppliers during major economic and financial crises.

Originality/value

This research is the first to conceptualize buying firms' response options to financially distressed suppliers, to investigate the influence of dependence on buying firm's response and to reveal the consequences of the buying firm's response for the supplier's financial recovery.
Development of a framework for safety performance measurement of belt conveyor systems
Authors: Parmar Narendrasinh Jesangbhai , James Ajith Tom
Published: October 2021

Purpose

The purpose of this paper is to develop a framework for the safety performance measurement of belt conveyor systems.

Design/methodology/approach

A structural methodology of graph theory and matrix approach is used for developing a framework for safety performance measurement of belt conveyor systems.

Findings

The development of a framework for safety performance measurement of belt conveyor systems is essential for ensuring plant safety. For this, safety performance factors, including design and operating contextual factors of belt conveyor systems, are identified. The factors along with their interrelations are modeled using digraph. An equivalent matrix of the digraph provided safety performance function (SPF) of belt conveyor systems, leading to the development of a safety performance index (SPI).

Practical implications

The developed framework will enable the designers for evaluating and comparing alternative designs of conveyor systems from the safety viewpoint. The plant operators can make inferences from the SPI to identify the weak contextual factors in the plant and develop action plans for its mitigation.

Originality/value

The paper is novel and employs graph theory and matrix approach for safety performance measurement. The methodology helps in the quantitative evaluation of the safety performance of belt conveyor systems.
What is next for sustainable competitive advantages in pandemic outbreak context?
Authors: Teoh Bak Aun , Teoh Phern Chern , Tan Houng Chien , Ibrahim Amlus
Published: October 2021

Purpose

This paper aimed to validate the sustainable competitive advantage (SCA) measures in Malaysian electronics manufacturing organizations' context after the post coronavirus disease 2019 (COVID-19) outbreak. Post pandemic sustainability in competitive advantages have become a buzzword for Malaysian electronics industries in facilitating the value chain generation to consumers, besides enhancing profitability to the organization. SCAs are important when the manufacturer can provide something valuable to the market, and it differs from the competitors, especially during the crisis.

Design/methodology/approach

This study adopted the quantitative research approach in validating the SCA variables. The questionnaires were self-administered and randomly distributed among the electronics manufacturing organizations across Malaysia, with a total of 207 responses. Concisely, this research theoretically conceptualized SCAs as a multidimensional construct containing two dimensions: lower cost advantage (LCA) and differentiation advantage (DFA).

Findings

Besides, the findings ascertained the strategies to sustain the competitive advantages within an organization, which is underpinned by resource-based theory. In short, findings of this research would be an imperative implication for academicians and organization's policymakers to move forward towards advanced economy and Industrial Revolution 4.0 in the current global competitive environment.

Originality/value

There is no prescription of attaining competitive advantages that suits all conditions in Malaysian electronics industries; this implies that the literature gaps existed, and further research shall be conducted on SCAs.

Published: October 2021

Purpose

The warehouse industry is one of the backbones in the logistics operation which involves several activities i.e. storage, receiving, picking and shipping of goods/cargoes. This study analyzes the most important warehouse productivity indicators for improving warehouse operation efficiency.

Design/methodology/approach

This study presents an empirical methodology of the fuzzy analytical hierarchy process (FAHP) method, an integration between the fuzzy logic method with an analytical hierarchy process (AHP) method incorporated with the adoption of quantitative and systems theories under the modern management theory approach.

Findings

The results indicate that the weight values of the main criteria which lead by the criterion “Space (0.4005)” at the top ranking, followed by Information System (0.2445), Labor (0.2065) and Equipment (0.1484). In addition, the weight values and ranking of the 16 sub-criteria are also highlighted which the sub-criterion “Warehouse Management System (0.2445)” scores the highest weight value and followed by Storage Space Utilization (0.1043) and Throughput (0.0722) accordingly.

Research limitations/implications

Finally, this research contributed to enrich the literature, while highlighting a series of recommendations on the top three most significant productivity performance indicators that can be useful in further research.

Originality/value

A generic analysis model developed with the adoption of three study theories: quantitative, system and productivity theories.
Training of communities of sustainability practice through science and art
Authors: Alvarez-Castañon Lorena del Carmen , Romero-Ugalde Maricruz
Published: October 2021

Purpose

This paper aims to analyse the university experience of a social laboratory that mixes science and art to instruct communities of sustainability practice in heterogeneous contexts through interpretive audio-visual ethnography and cinematographic language.

Design/methodology/approach

The research approach was qualitative; data were triangulated through the thorough revision of the literature reported on this praxis, the auto-ethnography of the founder and CEO of this social laboratory and the systematization of the training categories from their documentaries. Furthermore, the analysis of this laboratory as a social innovation considered five categories, namely, critical interaction, shared values, social responsibility, digital competences and sustainability practices, and the projects profile was contrasted with the Sustainable Development Goals to show its sustainable approach.

Findings

The results showed that the best scored sustainability university communities are interdisciplinary. Moreover, the mix of science and art to train practice communities is a social innovation model that can go beyond university walls to influence its environment in dissimilar and socially disadvantaged territories.

Research limitations/implications

This research is based on a case from a Mexican university in a specific cultural context. Although the conclusions cannot be generalized, this case contributes to the need for pertinent complementarity between various classical methodological possibilities which, when articulated, enhance the research work.

Practical implications

The results could have practical implications if these are used as inputs in the development of university programmes with an interdisciplinary approach to sustainability training.

Originality/value

This research proposes this experience as an attempt to understand how to promote sustainable education among university communities that influence territories with wide social gaps.
Promoting sustainability assurance missions in the European Directive regulatory context
Authors: Gillet-Monjarret Claire
Published: October 2021

Purpose

The objective of sustainability assurance (SA) is to give credibility to nonfinancial information (Chenget al., 2015). In France, certain companies are subject by regulation to the implementation of SA in particular with the transposition of European Directive 2014/95/EU into national law. SA mission is a process by which an independent third-party organization (ITO) assures companies' nonfinancial information. Although this assignment is mostly performed by professional accountants, other providers can perform this assignment (Cohen and Simnett, 2015). In this research, the authors are interested in strategies for legitimizing the SA missions of independent third-party bodies. Assurance providers use their website to promote their missions. How do independent third-party bodies legitimize their assurance mission in a regulatory context relating to European Directive 2014/95/EU?

Design/methodology/approach

The authors carried out a discursive analysis of the promotion of SA missions on independent third-party body websites. A content analysis was performed on the collected textual data.

Findings

The results highlight different strategies for promoting the implementation of assurance missions aimed at legitimizing their new skills. Nevertheless, it appears that the providers make very little reference to the quality of nonfinancial information as the objective of SA missions.

Research limitations/implications

The research made it possible to study the promotion of SA through the websites of ITOs. Nevertheless, it would have been interesting to be able to question the ITOs to study their perceptions on their new SA missions.

Practical implications

The research enriches the literature on SA, particularly in a regulatory context relating to European Directive 2014/95/EU. It sheds light on the different strategies put in place by the providers appointed by regulations. From a managerial point of view, the study may allow ITOs to adapt their communication to promote extra-financial missions relating to the European Directive and thus to attract new clients. Finally at the institutional and regulatory level, this research highlights the need to put in place a precise framework relating to extra-financial assurance missions. This may also encourage countries not subject to the verification obligation to introduce such an obligation into their national law.

Originality/value

This is the first study to examine the promotion of SA practice by providers. In addition, very few studies have looked at this practice in a regulatory context and in particular within the framework of the European directive.
Status of BIM implementation in the Dominican Republic construction industry – an empirical study
Authors: Silverio Ana Karina , Suresh Subashini , Renukappa Suresh , Heesom David
Published: October 2021

Purpose

The increased use and proven benefits of building information modelling (BIM) worldwide suggest that its implementation could be of great help in diminishing inefficient traditional practices in the Dominican Republic (DR) construction industry. However, there is no empirical work about the implementation of BIM in the country. This study aims to critically appraise and document the status of the implementation of BIM in the DR to raise awareness and understand how BIM can be successfully implemented in the country.

Design/methodology/approach

A qualitative approach was adopted in which data was collected through semi-structured interviews, with the participation of 53 professionals from 36 construction organisations. The data collected was analysed with the method of content analysis.

Findings

The results confirmed that the DR is a BIM infant country. There are low levels of BIM implementation. The reasons why BIM is not implemented are explored, and a significant interest in implementing BIM in the future was also reported. Drivers to implement BIM include BIM benefits, competitive advantage and pressure from external partners. Current BIM approaches are mainly single-disciplinary, principally in architecture, and the effectiveness and scope of implementation are highly affected by intra-organisational and inter-organisational barriers.

Originality/value

There is a lack of research about the implementation of BIM in the DR. This study bridges this research gap by collecting primary data from Dominican construction organisations and construction professionals to report findings related to BIM implementation.
Delineating competency and opportunity recognition in the entrepreneurial intention analysis framework
Authors: Lim WeiLee , Lee Yvonne , Mamun Abdullah Al
Published: October 2021

Purpose

This study aims to delineate opportunity recognition as a competency from opportunity recognition as an outcome in the form of ideas and opportunities. In addition, a model was developed to examine the antecedents that lead to opportunity recognition competency, the intention to be an entrepreneur and finally, the actual number of ideas and opportunities discovered.

Design/methodology/approach

This study adopted cross-sectional design and collected quantitative data from a total of 247 randomly selected final year students from two private universities in Malaysia. Partial least squares structural equation modelling was applied to test the associations.

Findings

Study revealed that opportunity recognition competency and ability to develop ideas or exploitable opportunities are distinct constructs. Students with high competency in recognising opportunities are interested to be an entrepreneur but are not necessarily prepared with tangible ideas or exploitable opportunities. Absorptive capacity, entrepreneurial alertness and entrepreneurial knowledge were found to be significant predictors of opportunity recognition competency.

Practical implications

Firstly, in managing outputs of entrepreneurship education and trainings, opportunity recognition competency and number of ideas and opportunities should be separately and explicitly measured. Secondly, entrepreneurial alertness and entrepreneurial knowledge must be emphasised in entrepreneurial education or training on guiding students to be alert to information and honing their opportunity recognition competency skills through active search techniques.

Originality/value

This study is one of the few studies that clarify and empirically distinguish the concept of opportunity recognition as competency from opportunity recognition as an outcome in the forms of ideas and exploitable opportunities.
Apartment purchase under Shirkah-ul Milk and shariah compliance in Islamic banks: the perception of bankers and clients in Bangladesh
Authors: Uddin Mohammad Nazim
Published: October 2021

Purpose

Apartment purchase is an increasing investment trend in Islamic banks as clients trusted to eradicate the interest from financial dealings to capture the Islamic Principles. The paper aims to investigate the Shariah compliance in the investment of apartment purchases under Shirkah-ul milk in Bangladesh Islamic banks.

Design/Methodology/Approach

This study examined the perception of 125 clients and 25 managers from five key Islamic banks on the investment practices of apartment purchases. This study applied two data analysis methods: reflective measurement model was operated for examining the consistency, reliability, multicollinearity problems and validity; and Smart PLS-SEM (structural equation model) was used to investigate the direct impact of each explanatory variable on Shari’ah compliance in Islamic banks.

Findings

The results indicated that Islamic banks could not strictly maintain the Shariah compliance in apartment purchase. Such Shari’ah non-compliance is due to lack of knowledge and understanding with regard to bank’s objectives and philosophy, weak Shariah board, audit, weak regulatory body and supervision problem. These findings also firmly match clients’ and managers’ perceptions.

Research Limitations/Implications

A limited size of clients and bankers were involved in this study. The study focuses only on perceptions of Islamic banks’ clients and managers and avoids Muslim clients who involved conventional banks.

Originality/Value

This study provides Shariah-compliant alternatives in investment avenue for apartment purchases. These Shariah modes include Apartment Purchase Musharakah Mutanaqasa; Bai-Muajjal; and Apartment Purchases under Shirkah-ul Milk, which captures various limitations against current apartment purchase practices as well as to develop clients’ trust in Islamic banks.
Effects of intrinsic and extrinsic religiosity on value-expressive and social-adjustive attitude functions towards product
Authors: Çavuşoĝlu Sinan , Demirağ Bülent , Durmaz Yakup , Tutuş Gökhan
Published: October 2021

Purpose

This research aims to find out whether intrinsic and extrinsic religiosity affect product attitude functions (value-expressive, social-adjustive).

Design/methodology/approach

The population of the research consists of Muslim consumers in Turkey and Christian consumers in Portugal. Using the convenience sampling method, the data was obtained from 800 questionnaire forms which consist of 400 forms filled by Muslim consumers in Turkey and 400 forms filled by Christian consumers in Portugal. Smart PLS 3 (Partial Least Squares) statistical program was used to test hypotheses.

Findings

Results of the analyses show that the intrinsic religiosity of Muslim Consumers living in Turkey and Christian consumers living in Portugal negatively affects the value-expressive and social adjustive attitude. Extrinsic religiosity, on the other hand, has been found to have a positive effect on the functions of value-expressive and social-adjustive attitudes within the consumers of both countries.

Originality/value

There are studies on religiosity and consumer attitudes in the Turkish literature (Kurtoglu and Çiçek, 2013; Uyaret al., 2020; Demiraget al., 2020). Religiosity dimensions (intrinsic/extrinsic religiosity); however, have been neglected in the Turkish literature. This study provides a detailed evaluation of the effect of these dimensions on the dependent variable. Additionally, this study emphasizes the relational aspect of attitude dependent variable and religiosity dimensions by approaching it through the context of value-expressive and social-adjustive attitude. Thus, it is aimed to help practitioners and the literature gain a different perspective by referring to the attitude functions whose foundations were laid in the studies of Smithet al.(1956), Katz (1960) and strengthened in studies like Wilcoxet al.(2009). By comparing two different religions, the study results are analyzed in the context of different regions and cultures. This comparison can be beneficial both for local and international investors as religious and cultural factors play an important role in local and cultural investment decisions. The results of this study are thought to contribute to the consumer behavior literature and to public authorities in terms of evaluating the level of religiosity. In addition, this study can have practical results for the practitioners in both Portugal and Turkey.
Project manager knowledge hiding, subordinates’ work-related stress and turnover intentions: empirical evidence from Chinese NPD projects
Authors: Zhang Zhen , Min Min
Published: October 2021

Purpose

Although scholars have provided sufficient empirical evidence on the effect of peer knowledge hiding on new product development (NPD) project team outcomes, little attention has been given to the relationship between project manager knowledge hiding and individual outcomes. Drawing on the job resources-demands model and a dyadic stressor perspective, this study aims to explore the effect of project manager knowledge hiding on subordinates’ turnover intentions as well as the mediating roles of challenge- and hindrance-related stress.

Design/methodology/approach

This study conducted a multiple-source survey of NPD project managers and their subordinates in China. Hypotheses were tested by using data collected from 171 manager–subordinate dyads in NPD projects.

Findings

The findings revealed that project manager knowledge hiding was positively associated with subordinates’ turnover intentions, challenge-related stress and hindrance-related stress. Project manager knowledge hiding imposed a positive indirect effect on turnover intentions through hindrance-related stress, whereas the mediating effect of challenge-related stress was not significant.

Originality/value

To the best of the authors’ knowledge, this study is one of the first to investigate the individual outcomes of top-down knowledge hiding as well as the mediating roles of challenge- and hindrance-related stress in the context of NPD projects.
Employee acceptance of online platforms for knowledge sharing: exploring differences in usage behaviour
Authors: Nguyen Tuyet-Mai , Malik Ashish
Published: October 2021

Purpose

This paper aims to examine the technology acceptance model’s applicability in understanding employees’ acceptance of online platforms for knowledge sharing in organisations. Specifically, this research explores gender differences in using online platforms for sharing knowledge at the workplace in an emerging market context and the role of individuals’ motivation in online platform usage in organisations.

Design/methodology/approach

A web-based survey was conducted in Vietnam with 290 responses from employees in the banking and insurance industries.

Findings

Both intrinsic and extrinsic motivations influenced the perceived ease of use, perceived usefulness and online platform usage for knowledge sharing. The results also confirm a significant influence of perceived ease of use directly on knowledge sharing behaviour using online platforms and indirectly via perceived usefulness. Regarding gender differences, perceived ease of use was more salient in women, while men considered perceived usefulness to a greater extent.

Research limitations/implications

This study provides a complete picture of gender, motivation and technology used for knowledge sharing in organisational settings.

Originality/value

This research has provided additional insight into the importance of gender and motivation in technology acceptance. By doing this, this study helps organisations capture the potential of valuable human resources for their competitiveness.
Service user and carer representatives’ experiences of the personal effects of involvement in clinical psychology training
Authors: Hill Adam , Tickle Anna , De Boos Danielle
Published: October 2021

Purpose

Extant literature exploring service user (SU) involvement in clinical psychology training has been limited by its sampling from singular training programmes and its restricted application of psychological theory. This research seeks to counter limitations by exploring SUs’ experiences across multiple clinical psychology training programmes in the UK and by deductively applying psychological theory relating to power, recovery, identity and group development.

Design/methodology/approach

Semi-structured interviews were conducted with 14 participants. A deductive thematic analysis was used to analyse qualitative data.

Findings

Five main themes were identified: environment determines sense of safety; meeting challenges; sense of purpose, worth and value; the person you see now is not the person I was; and wanting to break the glass ceiling.

Research limitations/implications

Carers are underrepresented and the sample does not contain SUs who were no longer involved in training.

Practical implications

It is important that the environment fosters psychological safety for SUs, via positive and supportive relationships with trainees and staff, with SUs being treated as equals and financially reimbursed as such. SUs and professionals need to explore managing and sharing power to enable SUs to feel valued and to reap benefits from involvement, including developing a positive sense of identity.

Originality/value

The research is part of the early literature exploring SUs’ experiences of involvement in clinical psychology training and is, to the best of the authors’ knowledge, the first to explore the personal effects of involvement across multiple programmes.
Global money laundering appeal index: application of principal component analysis
Authors: Tiwari Milind , Gepp Adrian , Kumar Kuldeep
Published: October 2021

Purpose

The paper aims at developing a global ranking system determining a country's appeal as a destination for money laundering.

Design/methodology/approach

This paper uses principal component analysis (PCA), with a mix of standardised and unstandardised components relating to attractiveness, economic freedom and money laundering risk to come up with an index of money laundering appeal.

Findings

Four components relating to economic feasibility, financial liberty, government spending and tax regime are critical in influencing a country's money laundering appeal.

Research limitations/implications

This paper attempts to use a standardised and replicable methodology to condense into a single measure the complex and multifaceted phenomenon of a country's appeal as a destination for money laundering, thus avoiding the difficulty associated with precisely calculating illicit financial flows.

Practical implications

The ranking system could be used to determine the destinations attractive for laundering money. Such information can be used to come up with more effective preventative strategies to combat phenomena responsible for the stagnation of economic growth through tax evasion, corruption and creation of non-competitive markets.

Originality/value

It is the first attempt to use a statistical technique to understand the underlying components of a country's money laundering appeal.
Urban regeneration strategies and place development in contemporary Tokyo: the case of Shibuya Station area
Authors: Reggiani Marco
Published: October 2021

Purpose

This paper aims to shed light on current initiatives of urban regeneration around the Shibuya Station area within the context of contemporary Tokyo’s place development strategies. The objectives are twofold: to illustrate the characteristics of the plans and the planning approaches framing the interventions; and to identify the strategies employed to reshape the cityscape.

Design/methodology/approach

Using a case study approach, this paper combines data from historical and archival research, as well as policy documents and plans. These are supplemented by data from extensive fieldwork undertaken between 2015 and 2019 to critically assess and interpret the implemented policies and the outcomes of the regeneration.

Findings

The paper provides insight into the ongoing urban regeneration around the Shibuya Station area and identifies five key themes that summarise the strategies employed to transform the urban landscape in the area. Despite the apparent success and some innovations introduced by the redevelopment project, critical issues remain–especially around the privatisation of public space and the lack of a holistic approach to sustainability.

Originality/value

The paper examines a significant and timely case of urban regeneration. By critically discussing the implications of the redevelopment around Shibuya Station in the context of Tokyo’s current place development strategies, the study highlights the importance of an inclusive notion of sustainable development and contributes to the debate around Japanese urbanism and urban regeneration.
Preparation and evaluation of antimicrobial thiadiazol azo disperse dyes as colored materials in digital transfer printing ink for printing onto polyester fabric
Authors: Ali Ali A. , Elsawy Maha Mohammed , Salem Salem S. , El-Henawy Ahmed A. , Abd El-Wahab Hamada
Published: October 2021

Purpose

Paper aims to preparation of new acid disperse dyes based on thiadiazol derivatives and evaluation of their use as antimicrobial colorants in digital transfer-printing ink formulations for printing onto polyester fabric substrates.

Design/methodology/approach

New disperse dyes based on 1,3,4 - thiadiazol derivative (dyes 1–3) were prepared and evaluated by different analysis then formulated as colored materials in the ink formulations. The viscosity, dynamic surface tension and particle size distribution of the prepared inks were measured. The printed polyester fabric substrates were tested using a variety of tests, including light fastness, washing, alkali perspiration and Crock fastness, as well as depth of penetration. Density-functional theory (DFT) calculations were carried out at the Becke3-Lee-Yang-parr (B3LYP) level using the 6–311** basis set, and the biological activity of the prepared disperse dyes was investigated.

Findings

The obtained results of the physical of the prepared ink revealed that thiadiazol disperse ink is a promising ink formulation for polyester printing and agrees with the quality of the printed polyester fabric. The optimization geometry for molecular structures agreed with the analysis of these compounds. The HOMO/LUMO and energy gap of the studied system were discussed. The molecular docking analysis showed strong interaction with DNA Gyrase and demonstrated to us the high ability of these inks to act as antimicrobial agents.

Practical implications

The prepared inks containing the prepared thiadiazol disperse dye were high-performance and suitable for this type of printing technique, according to the results. The prepared inks resist the growth of microorganisms and thus increase the ink's storage stability.

Originality/value

The prepared disperse dyes based on 1,3,4 - thiadiazol derivative (dyes 1–3) can be a promising colorant in different applications, like some types of paint formulations and as a colorant in printing of different fabric substrates.
Team learning process: a longitudinal study in dynamic situation
Authors: Kérivel Thibault , Bossard Cyril , Kermarrec Gilles
Published: October 2021

Purpose

This paper aims to explore team learning processes used by soccer players in a professional training context by focusing on their identification and evolution for 22 months.

Design/methodology/approach

A soccer team from a professional academy participated to this study based on six training sessions. Qualitative data on training sessions were collected. Data analysis followed four steps: reporting the game timeline and behaviours connected to each situation; coding verbal data by delineating meaningful units of activity; classifying meaningful units of activity according to team learning processes derived from previous studies; and providing a temporal graph representing occurrences of team learning processes at each training session.

Findings

Results showed that soccer players used 13 team learning processes during training sessions. Two processes are mainly mobilized to visualize the situation and to plan. A temporal graph was edited to represent processes evolve over training sessions. The latter illustrated a stability in team learning processes mobilization during the 22 months follow-up.

Research limitations/implications

This study complete knowledges about team learning by providing a fine-grained understanding of how players learn in teams and how team learning processes evolve over time.

Practical implications

This paper can help practitioners who manage teams in high temporal pressure situations to design adapted training programs.

Originality/value

This exploratory study highlights that the team learning processes usually mobilized “off-field” could also be used by team members in high temporal pressure situations, “on-field”. This study offers an original longitudinal approach that fits with some recent calls for contribution about team activity and could benefit to other research fields.
Autophagy in skin barrier and immune‐related skin diseases
Authors: Liu Chi , Gu Lei , Ding Jie , Meng Qianchao , Li Nan , Dai Guifeng , Li Qinying , Wu Xueyong
Published: October 2021

Autophagy is a process which is highly conserved in eukaryotes to degrade or recycle cytoplasmic components through lysosomes to maintain cellular homeostasis. Recent studies have shown that autophagy also plays critical roles in cell apoptosis, inflammation, pathogen clearance, and so on under stressed conditions and thereby has been linked to a variety of human disorders. The skin is the largest organ of the body and serves as the first line of defense against environmental insult. Skin as a nutrient‐poor environment requires recycling of limited resources via the autophagy machinery to maintain homeostasis. Therefore, dysregulation of autophagy has been linked to skin diseases. In this review, we describe the molecular machinery and regulation of autophagy, discuss its role in keratinocytes and skin barrier, skin immune cells, and immune‐related skin diseases including autoimmune skin disorders, allergic skin diseases, infectious skin disorders, and antitumor immunity against skin tumor. Finally, we highlight the potential of autophagy as a therapeutic target for immune‐related skin diseases, and delivery of autophagy‐related molecules (such as inducers, inhibitors, or nucleic acid molecules) by virtue of physical materials (such as nanoparticles) or biological materials (such as peptides) to skin topically may obtain clinical benefits in immune‐related skin diseases. Moreover, developing autophagy‐related gene product‐based biomarkers may be promising to diagnose immune‐related skin diseases.
The mating system affects the temperature sensitivity of male and female fertility
Authors: Baur Julian , Jagusch Dorian , Michalak Piotr , Koppik Mareike , Berger David
Published: October 2021

To mitigate the effects of climate change, it is important to understand species' responses to increasing temperatures. This has often been done by studying survival or activity at temperature extremes. Before such extremes are reached, however, effects on fertility may already be apparent.

Sex differences in the thermal sensitivity of fertility (TSF) could impact species persistence under climate warming because female fertility is typically more limiting to population growth than male fertility. However, little is known about sex differences in TSF.

Here we first demonstrate that the mating system can strongly influence TSF using the seed beetle Callosobruchus maculatus. We exposed populations carrying artificially induced mutations to two generations of short‐term experimental evolution under alternative mating systems, manipulating the opportunity for natural and sexual selection on the mutations. We then measured TSF in males and females subjected to juvenile or adult heat stress.

Populations kept under natural and sexual selection had higher fitness, but similar TSF, compared to control populations kept under relaxed selection. However, females had higher TSF than males, and strikingly, this sex difference had increased over only two generations in populations evolving under sexual selection.

We hypothesized that an increase in male‐induced harm to females during mating had played a central role in driving this evolved sex difference, and indeed, remating under conditions limiting male harassment of females reduced both male and female TSF. Moreover, we show that manipulation of mating system parameters in C. maculatus generates intraspecific variation in the sex difference in TSF equal to that found among a diverse set of studies on insects.

Our study provides a causal link between the mating system and TSF. Sexual conflict, (re)mating rates and genetic responses to sexual selection differ among ecological settings, mating systems and species. Our study therefore also provides mechanistic understanding for the variability in previously reported TSFs which can inform future experimental assays and predictions of species responses to climate warming.

Deepened snow cover mitigates soil carbon loss from intensive land‐use in a semi‐arid temperate grassland
Authors: Li Ping , Sayer Emma J. , Jia Zhou , Wu Yuntao , Deng Meifeng , Wang Xin , Liu Chao , Wang Bin , Wang Yang , Bai Yongfei , Liu Lingli
Published: October 2021

Carbon (C) loss due to soil erosion is a major issue in semi‐arid grasslands. The extent of soil erosion is determined by soil properties and vegetation structure, especially during the non‐growing season. In many Inner Mongolian grasslands, intensive land‐use, such as overgrazing and mowing, has severely reduced plant cover and damaged soil structure, which has exacerbated soil C loss by erosion. At the same time, increasing winter snowfall due to climate change is stimulating plant growth and altering plant composition. However, we do not know how changes in winter snow cover interact with land‐use practices to regulate soil C loss due to erosion.

Here, we conducted a 6‐year snow manipulation experiment under different land‐use practices (control; moderately mowed, MM; heavily mowed, HM) to measure net changes in soil depth, soil C, plant biomass and vegetation structure.

After 6 years, soil C loss under ambient snow was three times greater in the MM and four times greater in the HM treatment compared with controls during non‐growing season. However, deepened winter snow alleviated erosion‐induced soil C loss by 14%, 47%, 16% in the controls, MM and HM treatments respectively.

The severity of soil C loss declined with increasing above‐ground biomass (AGB), surface root biomass and vegetation structure. Vegetation structure and AGB explained more of the variation in soil C loss than surface root biomass, possibly because a complex canopy and plant cover increases overall surface roughness, thereby reducing soil C loss. Intensified land‐use reduced AGB, surface root biomass and vegetation structure, but deepened snow increased overall surface roughness by promoting AGB. Hence, our study demonstrates that deepened snow can alleviate soil C loss due to land‐use practices by promoting AGB.

Variability in environmental persistence but not per capita transmission rates of the amphibian chytrid fungus leads to differences in host infection prevalence

Heterogeneities in infections among host populations may arise through differences in environmental conditions through two mechanisms. First, environmental conditions may alter host exposure to pathogens via effects on survival. Second, environmental conditions may alter host susceptibility, making infection more or less likely if contact between a host and pathogen occurs. Further, host susceptibility might be altered through acquired resistance, which hosts can develop, in some systems, through exposure to dead or decaying pathogens and their metabolites. Environmental conditions may alter the rates of pathogen decomposition, influencing the likelihood of hosts developing acquired resistance.

The present study primarily tests how environmental context influences the relative contributions of pathogen survival and per capita transmission on host infection prevalence using the amphibian chytrid fungus (Batrachochytrium dendrobatidis; Bd) as a model system. Secondarily, we evaluate how environmental context influences the decomposition of Bd because previous studies have shown that dead Bd and its metabolites can illicit acquired resistance in hosts. We conducted Bd survival and infection experiments and then fit models to discern how Bd mortality, decomposition and per capita transmission rates vary among water sources [e.g. artificial spring water (ASW) or water from three ponds].

We found that infection prevalence differed among water sources, which was driven by differences in mortality rates of Bd, rather than differences in per capita transmission rates. Bd mortality rates varied among pond water treatments and were lower in ASW compared to pond water.

These results suggest that variation in Bd infection dynamics could be a function of environmental factors in waterbodies that result in differences in exposure of hosts to live Bd. In contrast to the persistence of live Bd, we found that the rates of decomposition of dead Bd did not vary among water sources, which may suggest that exposure of hosts to dead Bd or its metabolites might not commonly vary among nearby sites. Ultimately, a mechanistic understanding of the environmental dependence of free‐living pathogens could lead to a deeper understanding of the patterns of outbreak heterogeneity, which could inform surveillance and management strategies.

When navigating heterogeneous landscapes, large carnivores must balance trade‐offs between multiple goals, including minimizing energetic expenditure, maintaining access to hunting opportunities and avoiding potential risk from humans. The relative importance of these goals in driving carnivore movement likely changes across temporal scales, but our understanding of these dynamics remains limited.

Here we quantified how drivers of movement and habitat selection changed with temporal grain for two large carnivore species living in human‐dominated landscapes, providing insights into commonalities in carnivore movement strategies across regions.

We used high‐resolution GPS collar data and integrated step selection analyses to model movement and habitat selection for African lions Panthera leo in Laikipia, Kenya and pumas Puma concolor in the Santa Cruz Mountains of California across eight temporal grains, ranging from 5 min to 12 hr. Analyses considered landscape covariates that are related to energetics, resource acquisition and anthropogenic risk.

For both species, topographic slope, which strongly influences energetic expenditure, drove habitat selection and movement patterns over fine temporal grains but was less important at longer temporal grains. In contrast, avoiding anthropogenic risk during the day, when risk was highest, was consistently important across grains, but the degree to which carnivores relaxed this avoidance at night was strongest for longer term movements. Lions and pumas modified their movement behaviour differently in response to anthropogenic features: lions sped up while near humans at fine temporal grains, while pumas slowed down in more developed areas at coarse temporal grains. Finally, pumas experienced a trade‐off between energetically efficient movement and avoiding anthropogenic risk.

Temporal grain is an important methodological consideration in habitat selection analyses, as drivers of both movement and habitat selection changed across temporal grain. Additionally, grain‐dependent patterns can reflect meaningful behavioural processes, including how fitness‐relevant goals influence behaviour over different periods of time. In applying multi‐scale analysis to fine‐resolution data, we showed that two large carnivore species in very different human‐dominated landscapes balanced competing energetic and safety demands in largely similar ways. These commonalities suggest general strategies of landscape use across large carnivore species.
Spillover effects of corruption and democracy on territorial attractiveness of foreign direct investment in sub‐Saharan Africa

This article aims to analyse the spillover effects of corruption and democracy on foreign direct investment (FDI) attractiveness in sub‐Saharan Africa. To accomplish this, a dynamic spatial Durbin model that allows identification of both the endogenous and contextual effects was estimated. The results of the analysis show the presence of spatial interdependence of FDI attractiveness in sub‐Saharan African countries. The spillover effects transiting through democracy push FDI to agglomerate, while corruption pushes FDI to disperse. Furthermore, we find a strategic complementarity in FDI inflows between the countries in sub‐Saharan Africa, suggesting that an increase in FDI inflows to a host country is likely to stimulate FDI inflows to its neighbours. Therefore, they must coordinate their policies to attract FDI by setting up non‐discriminatory incentives between countries to limit the costs linked to attractiveness policies.
