Stable relationality and dynamic innovation: two models of collaboration in SME-driven offsite manufacturing supply chains in housing construction
Authors: Pablo Zelinna , London Kerry Anne 
Published: April 2020

PurposeThe study analyses collaborative practice in offsite manufacturing (OSM) housing supply chains, focusing specifically on supply chains driven by small and medium enterprises (SMEs). The study’s analysis builds on previous work where we argued that collaboration in OSM housing construction comprises nine elements. In this study, the authors demonstrate empirically that SMEs enact these collaborative practice elements in distinct ways, foregrounding key elements over others. One core model and two sub-models of collaboration emerge from our two case studies.Design/methodology/approachThe study analyses two SME-driven supply chains using qualitative case study techniques. Data were gathered through 12 semi-structured interviews conducted in two housing construction supply chains: one in South Australia, Australia, and another in Tasmania, Australia.FindingsA comparative case study of SMEs shows that collaboration in OSM supply chains has a number of common elements, including a champion for innovation, investment in long-term relationships, resourceful use of limited assets and physical co-location. However, SMEs can also enact these elements through a range of diverging collaborative strategies that can be distilled into different models: stable relationality and dynamic innovation.Originality/valueFindings provide a compelling empirical basis for arguing that SMEs can successfully lead OSM supply chains if key collaborative practice elements are strategically mobilised in ways that are suited to their strengths and limitations. The study therefore interrogates the widely held and often limiting assumption that OSM can only be driven by large organisations with access to capital assets, capacity to invest and undisputed bargaining power.

Published: April 2020

PurposeExcessive exposure to HAV can lead to hand–arm vibration syndrome (HAVS) which is a major health and well-being issue that can irreparably damage the neurological, vascular and muscular skeletal system. This paper reports upon field research analysis of the hand–arm vibration (HAV) exposure levels of utility workers in the UK construction sector when operating hand-held vibrating power tools.Design/methodology/approachAn empirical epistemological lens was adopted to analyse primary quantitative data on the management of hand-held tool trigger times (seconds) collected from field studies. To augment the analysis further, an interpretivist perspective was undertaken to qualitatively analyse interviews held with the participating company's senior management team after field study results. This approach sought to provide further depth and perspective on the emergent numerical findings.FindingsThe findings reveal that none of the operatives were exposed above the exposure limit value (ELV) and that 91.07% resided under the exposure action value (EAV). However, the Burr four parameter probability model (which satisfied the Anderson–Darling, Kolmogorov–Smirnov and chi-squared goodness of fit tests at α 0.01, 0.02, 0.05, 0.1 and 0.2 levels of significance) illustrated that given the current data distribution pattern, there was a 3% likelihood that the ELV will be exceeded. Model parameters could be used to: forecast the future probability of HAV exposure levels on other utility contracts and provide benchmark indicators to alert senior management to pending breaches of the ELV.Originality/valueHAV field trials are rarely conducted within the UK utilities sector, and the research presented is the first to develop probability models to predict the likelihood of operatives exceeding the ELV based upon field data. Findings presented could go some way to preserving the health and well-being of workers by ensuing that adequate control measures implemented (e.g. procuring low vibrating tools) mitigate the risk posed.
Reliability measures for a new general system using fuzzy non-homogenous Markov reward model under d-degradation levels
Authors: Temraz Neama 
Published: April 2020

PurposeIn this paper, new procedures for a fuzzy Markov reward model are introduced to find the reliability measures.Design/methodology/approachIt is supposed that the introduced system consisted of n identical units connected in parallel and each unit has m different types of failures. Also, each unit of the system is allowed to have d levels of degradation from a working state to complete failure. Non-homogeneous Markov reward model is used to construct the system of differential equations of the model. Procedures are proposed to obtain reliability measures of the model under considering that the failure and repair rates of the systems unit are fuzzy. An application is constructed to analyze a system of 2-unit, and results are shown graphically.FindingsNon-homogeneous Markov reward model is used to construct the system of differential equations of the model.Originality/valueAll papers in literature assumed Markov reward model with deterministic parameters. In this paper, a generalization of classical Markov reward model is introduced.
Let's get everyone involved! The effects of transformational leadership and organizational culture on organizational excellence
Authors: Lasrado Flevy , Kassem Rassel 
Published: April 2020

PurposeThis paper posited a dynamic relationship between transformational leadership, organizational culture, and organizational excellence in order to develop a better understanding of the casual linkages between these three areas.Design/methodology/approachThe research methodology includes a multi-item scale questionnaire survey which included 448 samples from United Arab Emirates (UAE) with an average response rate of 61.1%. The hypotheses were tested by applying structural equation modeling (SEM) and path analyses. Analyses used the Mplus software package.FindingsThe key finding in this study suggests that creating the involvement culture provides the all-inclusive participation and holistic engagement from employees, which consequently leads to organizational excellence.Research limitations/implicationsThe study is more focused on particular type of leadership and can extend to other types of leadership as well the other regions. The study extends the findings of previous studies that suggested authoritative was essential initially but that this would change with the emerging culture.Practical implicationsManagers should foster an involvement culture and adopt transformational leadership style in order to reap the benefits of the quality management approaches.Originality/valueFrom existing research on leadership in QM context, we adopt transformational leadership in connection with organizational culture and organizational excellence. The originality of the study lies in its quantitative approach to test an already demonstrated phenomenon about the relationship between transformational leadership, organizational culture and business excellence. This study significantly contributes to the literature on QM by discovering that organizations with transformational leadership styles and involvement or adaptability cultures can perform well and achieve organizational excellence.
Students’ perceptions of HEI regarding environmental sustainability – a comparative analysis
Authors: Correia Elisabete , Conde Fátima , Nunes Rosa , Viseu Clara 
Published: April 2020

Purpose
This paper aims to compare the environmental sustainability practices at the campus operations between two Portuguese higher education institutions (HEIs) at different stages of the implementation of an Eco-School Programme. It also seeks to analyse the involvement of the students in the process of implementing these practices in their institutions.

Design/methodology/approach
A questionnaire survey was carried out in two HEIs (a green and a non-green institution). Data were collected from a total of 832 students. Techniques of descriptive statistics and inferential statistical techniques such as the Mann-Whitney test, χ2 and Spearman correlation test, were applied.

Findings
The results obtained show that, from the students’ perspective, and in both institutions, there is still much to be done on the path towards sustainability, particularly in transport and landscaping. Significant differences were found only between some environmental sustainability practices at the campus level. However, students from the green institution are more participative in sustainability activities.

Practical implications
This study provides a picture of two HEIs’ sustainability behaviour from the students’ standpoint, which can be important for decision-makers in HEIs, in as much that students are one of the HEIs’ major stakeholder groups; furthermore, it enables them to better guide their efforts towards sustainability.

Originality/value
This paper focusses on the students’ perspective and their role in the sustainability initiatives undertaken by HEIs. It can be useful for future research that attempts to analyse the importance of HEIs’ stakeholder participation in sustainability.
Managing stressors in a detention facility: the need for supporting and safeguarding staff
Authors: Eades David N. 
Published: April 2020

Purpose
This paper aims to explore the impact of stressors and the strategies staff use to cope with these at a detention facility. It documents through case studies some of the triggers of trauma, possible coping mechanisms that might assist in navigating the associated stressors in a workplace and recommendations as to what might assist staff.

Design/methodology/approach
A naturalist approach was used in this research, using an ethnographic qualitative methodology. Grounded theory assisted in the analysis of the data to capture naturalistically the subjective experience of the participants of the study. Conversations occurred with staff who had worked in a detention facility using face to face semi-structured interviews. The structure was open-ended to allow the staff to discuss and share their experiences freely.

Findings
Stressors that impacted staff working in a detention facility resulted from areas such as heightened reactions from detainees because of the length of their detainment, detainee self-harm, dealing with the effects of an increase of substance abuse through detainees obtaining contraband and the associated violent reactions that can occur as a result. Adverse symptoms noted within the lives of staff included acute anxiety, sleeplessness, depression and tension within impersonal relationships, including family. What compounded the issue was staffs’ reluctance to talk about work stressors.

Research limitations/implications
The research used nine participants for case studies of staff who had formerly experienced various adverse impacts of stressors. This is not a comprehensive study, however, of the broader experiences of staff at an Australian detention facility. It does provide, however, a snapshot of the experiences of a small group who had significantly been impacted by the stressors of the workplace.

Practical implications
This paper provides fresh perspectives or initiatives that are needed to assist staff to navigate the changing environment of working in a detention facility. In particular, some support mechanisms and protective factors that could be put in place to curb the negative impact of stressors in the workplace and to mitigate against long term stress disorders developing in the personal lives of staff.

Social implications
Many staff are not getting the help they need to cope with the emotional distress they experience in their workplace. However, there are practical interventions to support staff in managing the stressors they face. These will be outlined in this article.

Originality/value
This study was carried out with the goal of giving staff a voice and to capture their former experiences in their vocational responsibilities in a venue that has had very limited research attention. This study has presented the challenges staff faced in a unique venue of working in a detention facility. It has documented some of the common stressors staff faced, the impact of such and some coping mechanisms used to handle them.
Institutional change and routine dynamics in service ecosystems
Authors: Tuominen Tiina , Edvardsson Bo , Reynoso Javier 
Published: April 2020

Purpose
This study aims to understand and explain how institutional change occurs at the level of value co-creation practices in service ecosystems. Despite the centrality of collective practices to the service ecosystems perspective, theoretically grounded explanations of how practices change and become institutionalized remain underdeveloped. Applying the theory of routine dynamics, this paper addresses two questions as follows: what does the institutional change mean at the level of value co-creation practices and what processes underlie these changes?

Design/methodology/approach
The study develops a conceptual framework that characterizes value co-creation practices as routines involving three aspects, namely, ostensive, performative and artifactual. As a key element in institutional change, the interplay between these informs an account of institutional change processes in service ecosystems.

Findings
The proposed conceptual framework specifies the conditions for institutional change in terms of value co-creation routines. First, any such change is seen to be grounded in alignment between changing institutional rules and the ostensive, performative and artifactual aspects of routines. Second, this alignment is seen to emerge through a dialectics of planned and practice-based activities during institutional change. An empirical research agenda is proposed for the analysis of institutional change processes in different service ecosystems.

Originality/value
This conceptual framework extends existing accounts of how service ecosystems change through the contributions of multiple actors at the level of value co-creation practices.
Leadership and performance of Millennial generation in Brazilian companies
Authors: Silva Rodrigo , Dutra Joel , Veloso Elza Fátima Rosa , Trevisan Leonardo 
Published: April 2020

PurposeThe purpose of this study is to analyze the effect of the relationship between leadership and engagement on the individual performance of Millennial generation professionals.Design/methodology/approachA survey was carried out with higher education business school students in Brazil. The sampling procedure involved a convenience selection of Millennial generation professionals who are employed and have recently undergone a performance evaluation process. The professionals answered a questionnaire about their perception of an empowering and directive leader, engagement, human resource practices and performance.FindingsThe authors demonstrated the potential of leaders to generate engagement and influence performance, showing the need for companies to become involved in the leadership process by defining appropriate leader profiles and establishing clear practices and criteria for their actions with regard to Millennial generation.Practical implicationsThe potential of empowering leadership to generate engagement, and that of directive leadership to influence performance, show the need for companies to become involved in the leadership process by defining appropriate leader profiles and establishing clear criteria for their actions toward Millennial generation.Originality/valueIn Brazil, empowering leaders do not directly influence their subordinates’ performance, unlike what was found in previous studies. Thus, it may be that they also do not perceive, or are not working in, more flexible or participative workplaces, which interferes with the perception of the direct relationship between the leadership’s actions and their personal performance.

Published: April 2020

SummaryOuter membrane vesicles (OMVs) are lipid nanoparticles released by Gram‐negative bacteria, which play multiple roles in bacterial physiology and adaptation to diverse environments. In this work, we demonstrate that OMVs released by the environmental pathogen Chromobacterium violaceum deliver the antimicrobial compound violacein to competitor bacteria, mediating its toxicity in vivo at a long distance. OMVs purified by ultracentrifugation from the wild‐type strain, but not from a violacein‐abrogated mutant ΔvioABCDE, contained violacein and inhibited several Gram‐positive bacteria. Competition tests using co‐culture and transwell assays indicated that the C. violaceum wild‐type strain killed Staphylococcus aureus better than the ΔvioABCDE mutant strain. We found that C. violaceum achieves growth phase‐dependent OMV release by the concerted expression of two quorum sensing (QS)‐regulated pathways, namely violacein biosynthesis and VacJ/Yrb system. Although both pathways were activated at high cell density in a QS‐dependent manner, the effect on vesiculation was the opposite. While the ΔvioABCDE mutant produced twofold fewer vesicles than the wild‐type strain, indicating that violacein induces OMV biogenesis for its own delivery, the ΔvacJ and ΔyrbE mutants were hypervesiculating strains. Our findings uncovered QS‐regulated pathways involved in OMV biogenesis used by C. violaceum to package violacein into OMVs for interbacterial competition.
Effects of masting on seedling establishment of a rodent‐dispersed tree species in a warm‐temperate region, northern China

Published: April 2020

AbstractMasting is an evolutionary strategy used by plants to promote seed survival and/or seed dispersal under animal predation, but its effects on seedling establishment in field condition are rarely tested by long‐term experiments incorporating combined effects of seed and animal abundance. Here, we tracked seed production, rodent‐mediated seed dispersal, and seedling establishment in Armeniaca sibirica from 2005 to 2014 in a warm‐temperate forest in northern China, and examined the effects of seed abundance and per capita seed availability on seed fate and seedling recruitment rate. Our results showed that seed abundance or per capita seed availability generally benefited the seedling recruitment of A. sibirica through increasing dispersal intensity, supporting predator dispersal hypothesis. However, seedling recruitment showed satiated or even dome‐shaped association with per capita seed availability, suggesting the benefit to trees would be decreased when seed abundance were too high as compared to rodent abundance (a satiated effect). Our results suggest that the predator dispersal and satiation effects of masting on seedling recruitment can operate together in one system and conditionally change with seed and animal abundance.
Rainfall Interception Based on Indirect Methods: A Case Study in Temperate Forests in Oaxaca, Mexico
Authors: Fernández Tania , Trejo Irma 
Published: April 2020

AbstractRainfall interception represents the amount of water trapped in natural cover that is not drained directly to the ground. Intercepted rainfall may evaporate after a rain event, making it one of the main drivers of water balance and hydrologic regionalization. This process can be affected by factors such as climate, altitude, vegetation type, and topography. Here is a simple method of calculating rainfall interception in temperate forests using in Santa Maria Yavesia, Oaxaca, and Mexico as an illustrative study area. We used two rain gauges to measure net precipitation (Np) under the canopy at each study site and one gauge outside the canopy to obtain gross precipitation (Gp). Throughfall (Th) was indirectly measured using hemispherical photographs. Rainfall interception was obtained through a combination Th and Gp and Np. The mean rainfall interception was 50.6% in the Abies forests, 23%–40% in the coniferous‐mixed forests, and 27.4% in the broad‐leaved forests. We classified rainfall events by intensity to determine the effect of canopy structure and precipitation and found that 75% of the events were weak events, 24% were moderate events, and 1% were strong events. In addition, we found that rainfall interception was lower when the intensity of precipitation was higher. Our method can be replicated in different ecosystems worldwide as a tool for assessing the influence of rainfall interception in terms of ecological services.
Who is where in the Plastisphere, and why does it matter?
Authors: Arias‐Andres Maria 
Published: April 2020

To fully understand how plastic is affecting the ocean, we need to understand how marine life interacts directly with it. Besides their ecological relevance, microbes can affect the distribution, degradation and transfer of plastics to the rest of the marine food web. From amplicon sequencing and scanning electron microscopy, we know that a diverse array of microorganisms rapidly associate with plastic marine debris in the form of biofouling and biofilms, also known as the “Plastisphere.” However, observation of multiple microbial interactions in situ, at small spatial scales in the Plastisphere, has been a challenge. In this issue of Molecular Ecology Resources, Schlundt et al. apply the combination labelling and spectral imaging – fluorescence in situ hybridization to study microbial communities on plastic marine debris. The images demonstrate the colocalization of abundant bacterial groups on plastic marine debris at a relatively high taxonomic and spatial resolution while also visualizing biofouling of eukaryotes, such as diatoms and bryozoans. This modern imaging technology provides new possibilities to address questions regarding the ecology of marine microbes on plastic marine debris and describe more specific impacts of plastic pollution in the marine food webs.
Chromosome‐level hybrid de novo genome assemblies as an attainable option for nonmodel insects

Published: April 2020

AbstractThe emergence of third‐generation sequencing (3GS; long‐reads) is bringing closer the goal of chromosome‐size fragments in de novo genome assemblies. This allows the exploration of new and broader questions on genome evolution for a number of nonmodel organisms. However, long‐read technologies result in higher sequencing error rates and therefore impose an elevated cost of sufficient coverage to achieve high enough quality. In this context, hybrid assemblies, combining short‐reads and long‐reads, provide an alternative efficient and cost‐effective approach to generate de novo, chromosome‐level genome assemblies. The array of available software programs for hybrid genome assembly, sequence correction and manipulation are constantly being expanded and improved. This makes it difficult for nonexperts to find efficient, fast and tractable computational solutions for genome assembly, especially in the case of nonmodel organisms lacking a reference genome or one from a closely related species. In this study, we review and test the most recent pipelines for hybrid assemblies, comparing the model organism Drosophila melanogaster to a nonmodel cactophilic Drosophila, D. mojavensis. We show that it is possible to achieve excellent contiguity on this nonmodel organism using the dbg2olc pipeline.
