Structures and relationships in organizational learning for change
Authors: Karnopp Jennifer 
Published: May 2022

PurposeMuch of the scholarship relating to educator learning in the context of school change centers on promising organizational structures that support educator knowledge-building and sharing. However, recent studies have found that educators' social networks also enhance learning of new practices. This study aims to explore how informal interactions support organizational learning in schools.Design/methodology/approachApplying structuration theory to concepts of organizational learning mechanisms, this paper proposes a framework for examining informal interactions and organizational learning. Employing an exploratory sequential mixed-methods design, this paper utilizes social network analysis of survey data and thematic analysis of interview data of a purposive sample of participants in a rural school district.FindingsWithin this rural district, organizational and social conditions supported recursive interactions where educators developed and shared knowledge of new instructional practices. Organizational resources and routines, and individuals' habits of mind mediated these recursive interactions, resulting in somewhat dependable knowledge-sharing spaces. Through these recursive interactions between individual agents acting within the opportunities and constraints of the normalized organizational expectations of each school, informal knowledge structures emerged.Originality/valueThis article applies structuration theory to examine organizational learning mechanisms in schools. This novel approach provides researchers with a new perspective on the organizational learning process—one that facilitates the exploration of the role of informal knowledge-building in this process.

Authors: Alshboul Odey , Shehadeh Ali , Tatari Omer , Almasabha Ghassan , Saleh Eman 
Published: May 2022

Purpose
Efficient management of earthmoving equipment is critical for decision-makers in construction engineering management. Thus, the purpose of this paper is to prudently identify, select, manage and optimize the associated decision variables (e.g. capacity, number and speed) for trucks and loaders equipment to minimize cost and time objectives.

Design/methodology/approach
This paper addresses an innovative multiobjective and multivariable mathematical optimization model to generate a Pareto-optimality set of solutions that offers insights of optimal tradeoffs between minimizing earthmoving activity’s cost and time. The proposed model has three major stages: first, define all related decision variables for trucks and loaders and detect all related constraints that affect the optimization model; second, derive the mathematical optimization model and apply the multiobjective genetic algorithms and classify all inputs and outputs related to the mathematical model; and third, model validation.

Findings
The efficiency of the proposed optimization model has been validated using a case study of earthmoving activities based on data collected from the real-world construction site. The outputs of the conducted optimization process promise the model’s originality and efficiency in generating optimal solutions for optimal time and cost objectives.

Originality/value
This model provides the decision-maker with an efficient tool to select the optimal design variables to minimize the activity's time and cost.
Linking online and offline intergenerational knowledge transfer to younger employees’ innovative work behaviors: evidence from Chinese hospitals
Authors: Wang Changyu , Dong Yihong , Ye Zixi , Feng Jiaojiao 
Published: May 2022

Purpose
Little is known about when younger employees’ intergenerational knowledge transfer (IGKT) – behaviors of acquiring knowledge from older employees – improves their innovative work behaviors (IWB), especially in hospitals. Taking into consideration the moderating roles of individual absorptive capacity (AC) and organization size, this study aims to develop a theoretical model to account for the associations of both online and offline IGKT with younger employees’ IWB.

Design/methodology/approach
The model was tested with a survey of 202 Chinese younger doctors (40 years old and below). Partial least squares structural equation modeling (PLS-SEM) was used to analyze the data.

Findings
The results showed that both online IGKT and offline IGKT have significant positive relationships with younger doctors’ IWB. Individual AC can strengthen the relationship between offline IGKT and IWB, and organization size can weaken the relationship. However, both individual AC and organization size do not significantly moderate the relationship between online IGKT and IWB.

Originality/value
The findings extend the understanding and application of individual-level knowledge-based view and media synchronicity theory by exploring the relationship of knowledge acquisition from older doctors through both online and offline communication channels with younger doctors’ IWB.
Green innovation and environmental awareness driven green purchase intentions
Authors: Zameer Hashim , Yasmeen Humaira 
Published: May 2022

PurposeThe purpose of this study is to explore the role of environmental awareness, environmental concerns, and green innovation toward green purchase intentions. This paper theoretically extends the existing knowledge on the subject matter and adds value to the existing knowledge.Design/methodology/approachBased upon the existing literature and relevant theories the study developed several assumptions/hypotheses. To test the hypothesis, a comprehensive data set that was collected through online survey method was utilized. For the empirical analysis the study employed structural equation modeling technique.FindingsThe results from the study indicated that environmental awareness significantly reinforce green purchase intentions. Whereas, the authors could not find evidence for the direct influence of green innovation on green purchase intentions. The analysis show, green product knowledge and environmental concerns partially mediate the relationship among environmental awareness and green purchase intentions. However, green product knowledge and environmental concerns fully mediate the relationship among green innovation and green purchase intentions.Originality/valueThe study measures the role of green innovation, environmental awareness, environmental concerns, and green product knowledge toward green purchase intentions which is pivotal for sustainable consumption. Similarly, the study adds value to the existing research on the management of environmental awareness and protection through reinforcing green purchases.
Synthesis, characterization, spectroscopic properties and computational studies of some new azo dyes derived from 5-chloro-8-hydroxy quinoline
Authors: Ashouri Mirsadeghi Fatemeh , Moradi Rufchahi Enayatollah , Zarrabi Saeid 
Published: May 2022

Purpose
The purpose of this study, 3-aminopyridine, 8-aminoquinoline and some new synthesized 2-aminobenzothiazoles were diazotized with nitrosyl sulfuric acid and subsequently coupled with 5-chloro-8-hydroxy quinoline to synthesize the corresponding heteroarylazo dyes 6–13.

Design/methodology/approach
The structures of dyes were characterized by mass, Fourier transform infra red, 1H proton nuclear magnetic resonance and ultra violet-visible spectroscopic techniques. Absorption spectra of the dyes were measured in acetic acid, ethanol, chloroform, acetonitrile, dimethyl formamide and dimethyl sulfoxide and correlated with the nature of the solvents and substituents. The effects of varying pH on the absorption wavelengths of the azo dyes were also studied. In addition, the acidity constants (pKa) of the dyes were determined using the spectrophotometric method in an ethanol-water mixture (80:20, v/v) at 20–23°C. Besides, density functional theory (DFT) calculations were carried out to compare the energies of proposed azo and hydrazone tautomers of the dyes.

Findings
The results showed that the withdrawing chloro groups on the diazo moiety have significant influence (red shift) on the electron absorption spectra of these dyes. In addition, introducing electron withdrawing chloro groups into the benzothiazoles moiety increased the acidic character of dyes.

Originality/value
The synthesized 7-hetroarylazo-5-chloro-8-hydroxy quinoline dyes are new members in the 8-hydroxyquinoline azo dyes family, where very few details regarding the synthesis of such dyes are reported before in the literature. They are unique in terms of synthesis, spectral properties and DFT calculations.

Authors: Mrkvička Tomáš , Krásnická Martina , Friebel Ludvík , Volek Tomáš , Rolínek Ladislav 
Published: May 2022

Purpose
Small- and medium-sized enterprises can be highly affected by losses caused by exchange rate changes. The aim of this paper was to find the optimal Value-at-Risk (VaR) method for estimating future exchange rate losses within one year.

Design/methodology/approach
The analysis focuses on five VaR methods, some of them traditional and some of them more up to date with integrated EVT or GARCH. The analysis of VaR methods was concentrated on a time horizon (1–12 months), overestimation predictions and six scenarios based on trends and variability of exchange rates. This study used three currency pairs EUR/CZK, EUR/USD and EUR/JPY for backtesting.

Findings
In compliance with the backtesting results, the parametric VaR with random walk has been chosen, despite its shortcomings, as the most accurate for estimating future losses in a medium-term period. The Nonparametric VaR confirmed insensitivity to the current exchange rate development. The EVT-based methods showed overconservatism (overestimation predictions). Every parametric or semiparametric method revealed a severe increase of liberality with increasing time.

Research limitations/implications
This research is limited to the analysis of suitable VaR models in a long- and short-run period without using artificial intelligence.

Practical implications
The result of this paper is the choice of a proper VaR method for the online application for estimating the future exchange rate for enterprises.

Originality/value
The orientation of medium-term period makes the research original and useful for small- and medium-sized enterprises.
Critical friendship as vital to the development of RPCK
Authors: Barrow Elizabeth C. , Norman Taylor 
Published: May 2022

PurposeThe purpose of this manuscript is to reveal how a White social studies teacher educator attempted to go from being a non-racist educator to an anti-racist educator (King and Chandler, 2016) and build her racial pedagogical content knowledge (RPCK).Design/methodology/approachThis manuscript is on part of a collaborative self-study. The authors used critical friendship (Schuck and Russell, 2005) and RPCK as the conceptual framework. The authors used self-study research methodology to analyze and interrogate analytical reflections, course syllabi, and course assignments. All data were analyzed through intentional and analytical dialogue over the course of weekly debriefs and three formal debriefing sessions.FindingsFindings from this study indicate that while stressful and challenging at times, the critical friendship with Taylor was vital in developing her RPCK. The friendship liberated and brought voice to her traditional, racialized self through intentional and analytic dialogue. This dialogue benefited the curricular review she was conducting on her content methods course to develop and integrate RPCK to her pedagogical mind.Research limitations/implicationsThe authors show that critical friendships can transform definitions of self and pedagogical practice. If social studies teacher educators are going to do the work of anti-racism, then it is our suggestion that they form a critical friendship to support their self-growth and pedagogical intentions before suggesting pedagogical innovations.Practical implicationsThis paper includes visual representation of RPCK that will allow other social studies teacher educators to teach the concept to their students. It also provides a framework to support others who want to work on their RPCK and racialized self.Originality/valueThis manuscript fulfills a need in the field by highlighting how a teacher educator can leverage a critical friendship to describe and reveal the enactment and analysis of balancing the self and practice regarding RPCK development. Visual representations of the conceptualization of RPCK are included.

Published: May 2022

AbstractBullous pemphigoid (BP) has been reported to be associated with an increased risk of venous thromboembolism (VTE). However, the exact time course is unclear, and no previous studies have been reported in the Asian population. This nationwide population‐based cohort study examined the risk of VTE among BP patients in Taiwan between 2007 and 2018. A total of 12 692 BP patients were 1:2 matched with non‐BP patients by age, sex, and propensity score of comorbidities. Cumulative incidence and Cox proportional hazards models were used to investigate the risk of VTE. The BP cohort had a significantly higher VTE rate than the non‐BP cohort (0.17% vs. 0.08%, p = 0.015) in 1 year; the finding was more prominent within the first 6 months after diagnosis. BP was a significant risk factor for VTE (hazard ratio [HR], 2.02; 95% confidence interval [CI], 1.01–4.06); the association mildly diminished but remained significant after extending the follow‐up period to 2 years (HR, 1.73; 95% CI, 1.06–2.81). Other significant risk factors for VTE included cancer, chronic liver disease and cirrhosis, and female sex. In conclusion, this study revealed a 2.02‐fold increased risk of VTE in patients with BP in Taiwan.

Abstract

Animals represent an overlooked source of horizontal redistribution of primary production and concentration of elements in ecosystems. For example, the high nutrient concentration of excretions by animals creates a mosaic of short‐term nutrient hotspots. However, how this impacts soil microbial communities, especially fungi, and in turn plant species diversity remains little known.

This study quantified the temporal dynamics of soil mineral nitrogen (N) availability and its relationship with soil fungal community and functional group composition in simulated high‐N patches in an Amazonian rain forest. We hypothesised that (H1) changes in local resource dynamics would increase the abundance of pathotrophs and reduce that of saprotrophs and that, (H2) compared with previously reported bacterial community dynamics, fungi would be more resilient after a pulse disturbance event.

A single urea pulse was applied and the relationship between fungal community composition and functional groups and soil N availability were determined before and twice after the urea treatment.

An increase in mineral N availability and soil pH two months after the applied urea pulse was found to be associated with significant changes in fungal community composition and the abundance of functional groups. There was a notable decrease in the relative abundance of saprotrophs, accompanied by an increase in plant pathogenic fungi. Five months after the treatment, no differences were detected either in mineral N availability and soil pH or the composition of fungal communities and functional groups between the control and urea treatment.

Synthesis. By locally favouring the abundance of plant pathogens, temporally short‐lived, but frequent high‐N patches created by animal excretions could potentially be involved in maintaining spatially and temporally variable soil microbial diversity and thus contributing to high plant community diversity in tropical rain forests as predicted by the Janzen–Connell hypothesis. The tendency of soil fungal communities in this study to return to their initial composition after 5 months suggests that they are resilient to perturbation by N pulse, and more so than previously observed in bacterial communities.
Men, suicide, and family and interpersonal violence: A mixed methods exploratory study
Authors: Fitzpatrick Scott J. , Brew Bronwyn K. , Handley Tonelle , Perkins David 
Published: May 2022

AbstractResearch has shown a link between gender, violence, and suicide. This relationship is complex, and few empirical studies have explored suicide and family and interpersonal violence perpetrated by men. Drawing on a coronial dataset of suicide cases and a mixed methods design, this study integrated a quantitative analysis of 155 suicide cases with a qualitative analysis of medico‐legal reports from 32 cases. Findings showed different types and patterns of family and intimate partner violence for men who died by suicide. Men used violence in response to conflict, but also to dominate women. Cumulative, interwoven effects of violence, mental illness, alcohol and other drug use, socioeconomic, and psychosocial circumstances were observed in our study population. However, the use of violence and suicidal behaviour was also a deliberate and calculated response by which some men sought to maintain influence or control over women. Health and criminal justice interventions served as short‐term responses to violence, mental illness, and suicidal behaviour, but were of limited assistance.
Verb Classes in the Resultative Construction in Germanic and Romance Languages
Authors: Métairy Justine 
Published: May 2022

AbstractThe present paper consists of a contrastive corpus‐based study of the (analytical) Resultative Construction (henceforth, RC) in culinary contexts (e.g. cut thin, whisk to a foam, roll into a ball). Four languages are investigated: two Germanic (i.e. Dutch and English) and two Romance languages (i.e. French and Spanish). Based on a sample of 1000 occurrences of the RC (by language) retrieved from our home‐made comparable corpus of cooking recipes, this study shows that: (i) both ‘strong’ (i.e. aspect‐shifting) and ‘weak’ (i.e. non‐aspect‐shifting) RCs are possible in the four languages studied (Washio 1997) – although the latter is said to be the only pattern available in Romance (Fontanals 2000; Mateu 2012; Bigolin & Ausensi 2021); (ii) a greater diversity of verbs occurs in the RC in Dutch and English, which suggests that the construction is still more productive in Germanic languages, even in culinary contexts; and (iii) in Romance, the productivity of the verb slot in the RC depends to a large degree on whether the resultative predicate can be encoded by a prepositional phrase.
Establishment of Beauveria bassiana as a fungal endophyte in potato plants and its virulence against potato tuber moth, Phthorimaea operculella (Lepidoptera: Gelechiidae)
Authors: Zhang Meng‐Di , Wu Sheng‐Yong , Yan Jun‐Jie , Reitz Stuart , Gao Yu‐Lin 
Published: May 2022

AbstractThe potato tuber moth, Phthorimaea operculella, is the most damaging potato pest in the world and is difficult to control as the larvae are internal feeders in the foliage and tubers. Entomopathogenic fungi that colonize plants as endophytes have lethal and sublethal pathological effects on insect pests. We show that Beauveria bassiana colonizes the aerial parts of potato plants endophytically after inoculation through soil drenching. Endophytic B. bassiana persisted in potato foliage for more than 50 days postinoculation. Bioassays indicated that foliage of B. bassiana‐inoculated potato plants were pathogenic against larvae of P. operculella. Sublethal experiments indicated that B. bassiana negatively affected the growth, development, and reproduction of P. operculella. Development experiments showed that the weight of P. operculella pupae reared on B. bassiana‐colonized potato plants (4.25 mg) was significantly less than that of those reared on uninoculated control plants (8.89 mg). Compared with newly eclosed larvae fed on control plants, those fed on B. bassiana‐inoculated plants had significantly lower survivorship, with only 17.8% developing to the adult stage. Oviposition of P. operculella females reared on B. bassiana endophytically colonized plants was significantly lower (35 eggs/female) than of those reared on uninoculated plants (115 eggs/female). This study demonstrates that endophytic B. bassiana can be a potential biological control agent for the control and management of P. operculella. Comparing pupal weights of P. operculella reared on potato plants inoculated with the B. bassiana strain GZGY‐1‐3 and on untreated control plants, pupae from the control plants were significantly heavier than those from treated plants.

AbstractBackgroundIn patients with non‐small cell lung cancer (NSCLC) harboring driver alterations, the efficacy of immune checkpoint inhibitors (ICIs) remains uncertain. Our study aimed to examine the first‐line ICI efficacy in patients with NSCLC harboring KRAS, MET, FGFR, RET, BRAF, and HER2 alterations in a real‐world setting.MethodsThis single‐center, retrospective cohort study included patients with advanced NSCLC harboring KRAS, MET, FGFR, RET, BRAF, HER2 alterations or driver‐negative, and were treated with first‐line ICI therapy. Best overall response, progression‐free survival (PFS), and overall survival (OS) were evaluated.ResultsSeventy‐eight patients with NSCLC were included (median age, 72 years): 67% were men, 15% were never‐smokers, and 83% had adenocarcinoma. The driver alterations involved KRAS (n = 21), MET (n = 6), FGFR (n = 3), RET (n = 2), BRAF (n = 2), HER2 (n = 1), and driver‐negative (n = 43). The partial responses for KRAS, MET, FGFR, RET, BRAF, HER2, and driver‐negative were 57%, 50%, 100%, 50%, 100%, 0%, and 47%, respectively. The median PFS (months) was 16.2 (95% confidence interval [CI]: 6.3– not reached [NR]) for KRAS, 2.8 (95% CI: 2.7–NR) for MET, 11.7 (95% CI: 5.9–NR) for other alterations (FGFR, RET, BRAF, and HER2), and 10.0 (95% CI: 3.7–14.3) for driver‐negative, respectively. The median OS (months) was 31.3 (95% CI: 9.0–NR) for KRAS, not reached for MET, 23.5 (95% CI: 18.3–NR) for other alterations, and 21.1 (95% CI: 15.2–NR) for driver‐negative, respectively.ConclusionsThe benefit of the first‐line ICI was similar in advanced NSCLC regardless of the driver alterations, except for MET alterations.
