An improved generalized plasticity model for rockfill materials and its experimental and numerical verification
Authors: Wang Xiang-Nan , Gao Yi-Zhao , Zhang Xiang-Tao , Yu Yu-Zhen , Lv He 
Published: November 2022

PurposeThe stress–strain behaviors of rockfill materials in dams are significantly affected by the anisotropy and grain crushing. However, these factors are rarely considered in numerical simulations of high rockfill dams. This study intends to develop a reasonable and practical constitutive model for rockfill materials to overcome the above problems.Design/methodology/approachThe effects of anisotropy and grain crushing are comprehensively considered by the spatial position of the reference state line. After the improved generalized plasticity model for rockfill materials (referred to as the PZR model) is developed and verified by laboratory tests, it is used with the finite element method to simulate the stress–strain behaviors of the Nuozhadu high core rockfill dam.FindingsThe simulated results agree well with the laboratory tests data and the situ monitoring data, verifying the reliability and practicability of the developed PZR model.Originality/valueA new anisotropic state parameter is proposed to reflect the nonmonotonic variation in the strength as the major principal stress direction angle varies. This advantage is verified by the simulation of a set of conventional triaxial tests with different inclination angles of the compaction plane. 2) This is the first time that the elastoplastic model is verified by the situ monitoring data of high core rockfill dams. The numerical simulation results show that the PZR model can well reflect the stress–strain characteristics of rockfill materials in high core rockfill dams and is better than the traditional EB model.
Le futur comme bien public: décoloniser le futur par la recherche-action participative anticipatoire
Authors: Bourgeois Robin , Feukeu Kwamou Eva , Karuri-Sebina Geci 
Published: November 2022

Objectif
L'objectif visé est de nourrir les réflexions sur la colonisation du futur dans le présent en mettant particulièrement l’accent sur le continent africain. Nous visons à explorer comment la recherche participative, et plus particulièrement la recherche-action anticipatoire, peut contribuer au processus de décolonisation effective.

Conception/méthodologie/approche
Considérant le futur comme un bien public, nous mobilisons une réflexion sur les processus coloniaux qui l’ont transformé, à bien des égards, en bien de club ou en bien privé. Nous faisons ensuite appel aux notions de production participative de connaissances et de recherche-action locale comme moyens de décoloniser le futur et de libérer l'imagination. Nous revisitons ensuite les principes de la recherche-action participative pour atteindre cet objectif et nous examinons les principales caractéristiques d'une recherche-action anticipatoire non coloniale dans le contexte des futurs de l'Afrique.

Résultats
Nous mettons en évidence les défis issus de la relation entre les efforts d'anticipation axés sur la recherche-action, la création d'une intelligence collective et la co-conception (codesign), dans le but d'encourager le processus de décolonisation. Cette démarche inclut des principes de conception, établit les bases pour un processus anticipatoire, potentiellement décolonial et envisage une possible réaction du système dominant à l’encontre de ce processus de décolonisation.

Implications/limitations
Il s’agit d’un travail conceptuel, qui ne fournit pas d’éléments testés sur le terrain. Toutefois, nous espérons que cela constituera un apport permettant de concevoir des méthodologies qui préviendront la colonisation du futur lors de la participation à des activités de recherche tournées vers les futurs en Afrique et ailleurs.

Originalité/valeur
Nous proposons une approche intégrale de la colonisation du futur, comme renouvellement d’une question ancienne. Nous articulons également cette démarche autour d’une réflexion sur la nature de ce que pourrait être une recherche-action anticipatoire décoloniale.
Narcissism and tradition: how competing needs result in more conflict, greater exhaustion, and lower performance
Authors: Harms P.D. , Bai Yuntao , Han Guohong (Helen) , Cheng Sheng 
Published: November 2022

Purpose
Although there have been considerable amounts of research documenting the effects of narcissism on workplace outcomes, studies of the impact of narcissism on job performance have produced inconclusive results. This study aims to provide insight into this issue by using a new model of narcissism, the Narcissistic Admiration and Rivalry Concept model to explore the processes by which narcissism can impact job performance.

Design/methodology/approach
Two studies (Study 1 with 1,176 employees and 217 managers cross-sectional data; Study 2 with 209 employees and 39 managers time-lagged data) were conducted and multilevel technique was used to test the research model.

Findings
Narcissistic rivalry is associated with higher levels of family–work conflict (FWC) and that these effects are magnified when narcissists also have competing demands in the form of expectations to conform to traditional values. Furthermore, this study documents that higher levels of FWC are associated with greater emotional exhaustion and lower job performance. However, narcissistic admiration only has direct effect on job performance.

Originality/value
This paper not only suggests that narcissism is a previously untested dispositional antecedent for FWC, but it also uses a facet-based approach to examine when and how narcissism impacts job performance.
Physical education teacher educators’ subjective theories about sustainability and education for sustainable development
Authors: Lohmann Julia , Goller Antje 
Published: November 2022

Purpose
Physical education (PE) and PE teacher education have great potential to target goals that are important from an education for sustainable development (ESD) perspective. However, ESD has not been studied extensively in the PE context. The purpose of this paper is to explore subjective theories of PE teacher educators about the concepts of sustainability and ESD because they are important precursors of implementing ESD in PE teacher education.

Design/methodology/approach
This study was conducted using a qualitative cross-sectional design. Subjective theories about sustainability and ESD from N = 9 PE teacher educators from a university in Germany were assessed in a multistage process, including semistructured interviews and the structure-formation technique. Subsequently, subjective theories were analyzed using qualitative content analysis.

Findings
The results reveal a wide range of subjective theories about the concept of sustainability. PE teacher educators described the dimensions of the sustainability concept (ecological, economic, social and political) to different depths and placed different emphases in terms of the levels of action needed to reach sustainable development. The subjective theories regarding the concept of ESD mostly include instrumental and emancipatory aspects of ESD. These subjective theories differ in that they emphasize different forms of ESD.

Originality/value
To the best of the authors’ knowledge, this study is the first of its kind to examine subjective theories regarding the concepts of sustainability and ESD in the context of PE teacher education. This study is one of only a few studies to provide detailed insights into the subjective theories of teacher educators in the area of sustainability and ESD.
Does the conventional money market overnight rate influence the investment rate of Islamic deposits? Evidence from Malaysia
Authors: Li Jingya , Liu Ming-Hua , Shrestha Keshab 
Published: November 2022

Purpose
The paper aims to examine whether the daily conventional money market overnight rate influences the monthly investment rate of Islamic deposits in Malaysia. The traditional approach, which averages the high-frequency data to match the low-frequency data, results in information loss for the high-frequency data.

Design/methodology/approach
The paper uses the mixed data sampling (MIDAS) model to study the relationship between Islamic banking and conventional banking. The Malaysian data are used for the analysis as Malaysia has one of the most developed Islamic financial industries in the world, and it is well-known for its dual banking system.

Findings
The evidence shows that the conventional overnight rate has a positive effect on the Islamic deposit rate. The results are consistent for Islamic deposit rates with different maturities. The positive aggregate effect holds when the lag length of the daily conventional overnight rate goes up to 90 days. Additional evidence shows that the daily conventional overnight rate has a similar effect on the conventional deposit rate.

Originality/value
This paper documents that the relationship between Islamic banking and conventional banking is not monotonous. When high-frequency data is averaged with low-frequency data, the non-linear relationship will be masked. It highlights the importance of using high-frequency data to get a detailed picture.

Authors: Šácha Jakub , Konderla Tomáš , Říhová Dana 
Published: November 2022

PurposeThe aim of this paper is to evaluate the influence of distance learning of the subject Operational Research in terms of the impact of the COVID-19 pandemic on the quality of teaching and the success of this course, to find out the satisfaction of students with the online learning, and the impact on the performance.Design/methodology/approachGrades of students from the subject were collected from the Faculty of Business and Economics of Mendel University in Brno between 2009 and 2021. A questionnaire concerning the views of students on online teaching of the subject and its comparison with face-to-face teaching was conducted, and the data obtained from 94 respondents were statistically processed by cluster analysis and the K-means method.FindingsA comparison of the results of examinations from the years taught in classical face-to-face form and from the period when teaching took place only online showed no significant effect on the final grades of the students. The results show that the students were basically divided into two-halves: one-half that preferred online teaching and the other that supported a more face-to-face form of teaching. Most of the students highly appreciated the tutorial videos provided because of the possibility of repeated viewing.Originality/valueThe paper shows that online teaching may be a suitable replacement for standard teaching. The paper answers the question whether some online elements can be integrated in the standard form of teaching.
What happens after psychosis? The support I have received
Authors: Makin Paul 
Published: November 2022

Purpose
The aim of the paper is to describe Paul Makin’s psychiatric treatment after he developed a psychosis.

Design/methodology/approach
Paul describes how, after an acute episode of psychosis, he ended up in a psychiatric unit. This is his narrative account of his recovery and the support he had in the community.

Findings
Paul’s story shows how mental health services are stretched both in hospital and also in the community.

Research limitations/implications
This is only one story. It is unusual in that Paul’s first diagnosis was alcohol dependence. It was a few years, after he had stopped drinking completely, that he developed a psychosis. One man, two recoveries.

Practical implications
Reading his story, Paul had problems getting any continuity of care. He does not blame the staff who were all doing their best, but a mental health system that has insufficient resources.

Social implications
While mental health is constantly in the news, resources seem as stretched as they always have been. They remain underfunded and undervalued.

Originality/value
Paul’s is one story of many, but it will find resonance with others who have accessed mental health services in recent years.
Comparison of properties at the interface of deposited IN625 and mixture of IN625 SS304L by laser directed energy deposition and SS304L substrate
Authors: Tudu Nehem , Baruah Mayuri , Prasad Shashi Bhushan 
Published: November 2022

Purpose
Prior to manufacturing, designing plays a vital role in the selection of materials and other design parameters. Therefore, during the deposition of materials, substrate materials provide support and affect the microstructure of the deposits, which may not be desirable in the manufactured product. Hence, the main purpose of the study is to analyse the behaviour of the microstructure at the interface of deposited material and substrate.

Design/methodology/approach
In this study, two blocks of Inconel 625 (IN625) and Stainless steel 304L (SS304L) metal powders were deposited on an SS304L substrate using laser directed energy deposition (DED) technique. Deposited blocks comprised 50% IN625 + 50% SS304L or 100% IN625. After deposition, microstructural behaviour at the interface of the deposits and substrates was analysed using different tests such as optical microscopy (OM), microhardness testing, X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). An improvement in microstructure was proposed by performing heat treatment of the deposited sample.

Findings
Formation of martensite and precipitates at the interface of the deposit and substrate was observed. Formation of martensite and precipitates such as α, carbide and δ phases were observed in OM and SEM images. Due to the formation of these phases, interface regions showed a peak in the hardness graphs. Post-heat treatment of the samples was one of the solutions to resolve these issues.

Originality/value
This paper suggests the formation of a heat-affected zone (HAZ) at the interface of the deposit and substrate, which may negatively affect the overall utility of the deposited part. The properties of the HAZ were investigated. To suppress these detrimental effects, post-heat treatment of the deposited sample was performed, and the samples were further analysed. The post-heat-treated samples exhibited as reduction in HAZ thickness and had more uniform hardness throughout the cross-section compared with the untreated samples.

Authors: Pascual-Fraile María Del Pilar , Talón-Ballestero Pilar , Villacé-Molinero Teresa , Ramos-Rodríguez Antonio-Rafael 
Published: November 2022

Purpose
This study aims to provide an overview, the state-of-the-art “research fronts”, the emerging themes of investigation and a research agenda of crisis communication for destinations’ image.

Design/methodology/approach
This research is conducted with a bibliographic coupling study, complemented with an H-Classic classification and a thematic analysis of the articles included in the four clusters provided by the bibliometric methodology (papers dating from 2017 to 2021, both years included).

Findings
Based on the bibliometric analysis, four thematic clusters were identified. Two of these clusters supply the “research fronts”, the most current themes in a scientific field: Cluster 1 addresses communication related to tourists’ safety, and cluster 2 enhances the role of stakeholders’ collaboration to create destinations resilience in crisis communication. The other two clusters highlight emerging themes for future investigation: Cluster 3 focuses on recovery marketing communication strategies for a post-crisis era, and cluster 4 analyses how crisis communication strategies contribute to reduce tourists’ risk perception and boosting travel intention. Finally, a future research agenda is proposed, based on the emerging themes from this study.

Originality/value
To the best of the authors’ knowledge, this is the first bibliometric study to analyse crisis communication for destinations’ image (pre-crisis, crisis and post-crisis). This study, which covers the most recent academic literature in this field, provides insights of communication strategies from recent crises and disasters within the “research fronts”. Besides, a research agenda useful for future scholar investigation is proposed with its emerging themes. These rising topics and learnings from past events could be used by destination marketing organisations in crisis communication for destination image recovery in the current post-pandemic scenario or in upcoming crises or disasters.
Medical or relational language? Problem and goal formulation in family therapy with adolescents conducted in a psychiatric outpatient setting
Authors: Taurogiński Bartłomiej , Bryniarska Antonina , Józefik Barbara 
Published: November 2022

AbstractThe constructionist view assumes that therapy participants' maps of understanding depend on the institutional context and their personal perspectives. The purpose of this study was to investigate the initial maps of difficulties reported by family members starting family therapy. 106 families that were referred to a psychiatric institution for outpatient family therapy were asked open‐ended questions regarding the context of the referral, and goal and problem formulation for the therapy. The data were analysed via the consensual qualitative research‐modified (CQR‐M) method, and comparisons between groups were performed. The obtained results show a diversity of perspectives. Of interest was the predominance of medical language in describing the problem and relational language in describing the goal of therapy. An analysis of differences between mothers, fathers, adolescent patient and their siblings was also performed. The findings highlight the complexity of notions that families start family therapy with and may help therapists navigate through the therapeutic contract formulation process.

Authors: Li Rui‐Zhe , Sun Li‐Fei , Li Rui , Wang Hong‐Jing 
Published: November 2022

AbstractBackgroundMinimally invasive radical hysterectomy has been reported to increase the risk of cancer relapse and death compared with open surgery in women with early‐stage cervical cancer. The use of a uterine manipulator is considered one of the risk factors.ObjectivesTo investigate whether women with early‐stage cervical cancer treated with minimally invasive radical hysterectomy without using uterine manipulator have oncological outcomes similar to those of open surgery.Search strategySearches were performed in MEDLINE, Embase and CENTRAL from their inception until 31 March 2022.Selection criteriaInclusion criteria were: (1) randomised controlled trials or observational cohort studies published in English, (2) studies comparing minimally invasive radical hysterectomy without using a uterine manipulator with open radical hysterectomy in women with early‐stage cervical cancer, and (3) studies comparing survival outcomes.Data collection and analysisTwo authors independently conducted data extraction and assessed study quality. We calculated the hazard ratios (HR) and the 95% confidence intervals (CI) using the inverse variance approach for survival outcome.Main resultsSix observational studies with 2150 women were included. The minimally invasive surgery group had a significantly higher risk of cancer relapse compared with open surgery group (HR 1.55, 95% CI 1.15–2.10).ConclusionsMinimally invasive radical hysterectomy without using a uterine manipulator resulted in an inferior recurrence‐free survival compared with open radical hysterectomy in the treatment of women with early‐stage cervical cancer.
Infection density pattern of Cardinium affects the responses of bacterial communities in an invasive whitefly under heat conditions

Published: November 2022

AbstractCommunities of bacteria, especially symbionts, are vital for the growth and development of insects and other arthropods, including Bemisia tabaci Mediterranean (MED), a destructive and invasive insect pest. However, the infection density patterns and influence factors of bacteria in whiteflies, which mainly include symbionts, remain largely unclear. To reveal the different density patterns of Cardinium in B. tabaci MED populations and the impacts of high temperatures on whiteflies with different Cardinium density infection patterns, 2 isofemale lines isolated from B. tabaci MED from the same geographical population of China and from B. tabaci MED collected from other countries and locations were examined using several techniques and methods, including fluorescence in situ hybridization (FISH), quantitative real‐time polymerase chain reaction (qPCR), 16S rRNA gene sequencing, and 2b‐RAD sequencing. The results showed that there were 2 different infection density patterns of Cardinium in B. tabaci MED (including 1 high‐density pattern and 1 low‐density pattern). For whiteflies with low‐density Cardinium, conventional PCR could not detect Cardinium, but the other techniques confirmed that there was a low level of Cardinium within hosts. High temperature significantly decreased the diversity of bacterial communities: the relative titer of Cardinium increased but the density of Rickettsia decreased in the isofemale line with high‐density Cardinium. However, high temperature did not influence the diversity and symbiont density in the line with low‐density Cardinium. Moreover, high temperature influenced the functions of bacterial communities in whiteflies with high‐density Cardinium but did not affect the bacterial functions in whiteflies with low‐density Cardinium. Our results provide novel insights into the complex associations between symbionts and host insects.
Different breeding lines of quinoa significantly influence the quality of baked cookies and cooked grains

Published: November 2022

AbstractTen advanced breeding lines of quinoa were evaluated for their physicochemical and functional characteristics. These novel breeding lines were used in two model foods, including cookies and cooked grains, to understand the influence of their characteristics on the product quality.The cookies were baked using whole quinoa flour, and the quality attributes of texture, physical dimensions, and color were measured. The whole quinoa grains were cooked with water at a 1:4 (w/w) grain‐to‐water ratio, and quality attributes including water uptake (WU‐G), bulk density (BD‐G), and cooking loss (CL‐G) were measured.Significant differences in the quality of both products as an impact of the breeding lines were observed. In baked cookies, the WAQ2 variety produced cookies with the lowest diameter, whereas cookies prepared with WAQ1 were significantly softer than other varieties. In terms of cooked quinoa, WAQ8 exhibited the highest WU‐G while WAQ1 showed the highest CL‐G.Correlations were observed between flour characteristics and final product quality. Cookie height was negatively correlated with protein content, whereas the water solubility index (WSI) of flours had a positive effect on the cookie hardness. The cooking characteristics of quinoa grains were found to be correlated with the thermal properties of whole quinoa flour.The results of this study will help determine the advanced breeding lines for release as commercial varieties and will also provide food processors with information to find suitable quinoa varieties for different food applications.Practical ApplicationNew quinoa breeding lines have been developed to be grown in the climate conditions of Washington State. These varieties were characterized to find correlations with food quality for cookies and cooked grains. The results from this study will help farmers navigate among the quinoa varieties and help commercial food producers use the optimal quinoa variety for their specific food products.
