Role of perceived HRM toward workplace bullying and turnover intention: mediating role of resilience and psychological health
Authors: Noopur  , Burman Richa 
Published: July 2021

Purpose The present research work has tried to investigate the impact of workplace bullying (WB) on turnover intention (TI); the study has also analyzed the effect of psychological health (PH) and resilience (RS) indirectly as mediators in between WB and TI. Further, the role of perceived HRM as a moderator directly and through RS has been tested. The study has been carried in the context of Indian IT sector.Design/methodology/approach The analysis of the moderated mediation model was done through PLS-SEM, owing to the medium size of the sample. SmartPLS 3 was used to check on the psychometric principles if any for the measurement model and also adopt a two-step analysis for the proposed model.Findings The findings of the present study have validated the empirical model, showing a significant relationship in between the proposed constructs. WB had a positive impact on TI whereas PH and RS turned out to be partial mediators but there was no evidence as to which mediator had a larger impact. Further, perceived HRM served as a moderator in between WB and TI and also through RS.Originality/value The study is first of its kind which has tried to investigate an exhaustive mediated moderation model in the Indian IT sector. The study has postulated that it is not just the HRM content but the perceptions of employees toward HRM which can be beneficial in resolving sensitive issues such as WB and eventually turnover intents.

Published: July 2021

PurposeEmbracing the theories of gender role and career socialization, this study focuses on young adults and explores gender differences in entrepreneurial intentions and entrepreneurship education.Design/methodology/approachBased on 203 young adults, this study employs a logistic regression model to test hypothesis 1 regarding differences in gender. In addition, it performs an analysis of variance using the two groups of young adults with and without academic entrepreneurship education to detect differences in entrepreneurial intentions between men (hypothesis 2) and women (hypothesis 3).FindingsThe empirical findings from a European country trailing in university-level entrepreneurship education confirm the dominant evidence that young women have lower entrepreneurial intentions than young men. In addition, women's proclivity toward entrepreneurship is lower with academic entrepreneurship education than without.Originality/valueThis study provides new evidence from Greece, which has few studies on entrepreneurship education at the tertiary level. Scholars are advised to keep track of the new pathway exploring linkages between gender, entrepreneurial intentions and entrepreneurship education. Policymakers in Europe are encouraged to establish an approach of tailoring university courses to their students. Currently, society will benefit from entrepreneurship education curricula targeting young women based on their particular needs and interests, while nurturing their entrepreneurial intentions.
Discussing: “The very idea of organizing becomes literally meaningless”
Authors: Letiche Hugo 
Published: July 2021

PurposeGunther Anders in the 20th century and Hartmut Rosa in the 21st have argued that the technics of organization – that is, its physical and social technologies, have from acceleration become so uncontrollable and unpredictable that circumstances actually outstrip awareness to the degree that intentional “organizing” is more a fable than a reality, as stated in the quote from Rosa that forms the title of this article.Design/methodology/approachIn this article, two critical theorists are examined who have fundamentally rejected the “control” thesis that dominates organization theory. It is a thesis that assumes that organizational change ought to be goal-directed, leadership driven and make use of soft and hard technologies to achieve defined objectives.FindingsThe prevailing “idea” of organizing has become illusionary. The technics of accelerationism have overpowered it. Not “organizing” but “ethic-sizing” is what remains as the: “What is to be done.”Originality/valueThe tradition of Gunther Anders and Hartmut Rosa (second and third generation Frankfurter School) and the implications of their work for our assumptions about the relations between technology, control and organization is for a first time evidenced in this article.

Published: July 2021

PurposeHow can social presence, participation and a sense of community be formed in an online setting without compromising on social connectedness through physical distancing? Under consideration of the goals for an Education for Sustainable Development, transformative science and the social techniques of Theory U, developed by Otto Scharmer (2016), an online Community of Inquiry of researchers, practitioners and learners was to be developed, followed and observed to discuss the question whether and how it was possible to create an awareness-based, future-oriented and socially committed online community that would enrich social transformation processes.Design/methodology/approachMethods of 1st, 2nd and 3rd person research were applied, as well as group discussions, one Mentimeter survey and one standardised questionnaire with an open question.FindingsResults indicate that it is not only possible to create a feeling of community in an online setting, but also point to the terms and conditions which act as enablers and influencers, like seeing each other face-to-face, collective check-ins and check-outs as well as small group break-out sessions. Video conferencing and the practicing of rules of conduct and communication, also referred to as netiquette, enable a transcendence of the physical distance to reach a feeling of belonging and social presence in the perception of the participants.Originality/valueIn line with global sustainable development, the study also sets an example for how to reduce personal emissions when planning an international conference. Also, it shows how to create online spaces to connect people worldwide, which will support to take over responsibilities as world citizens.

Authors: Zhou Lixin , Zhang Zhenyu , Zhao Laijun , Yang Pingle 
Published: July 2021

PurposeLarge volumes of users' creative information have rapidly become vital resources in the open innovation platforms, so it is crucial to identify high-quality information from massive creative information. However, the existing literature on the quality of creative information only focuses on the information characteristics or publishers' features.Design/methodology/approachIn this paper, the authors used the elaboration likelihood model to examine the joint effect of central route factors (information characteristics: timeliness, readability and sentiment) and peripheral route factors (source characteristics: personality traits, past successful experiences and social network location) on the quality of creative information. Furthermore, the author explored the moderating roles of companies' support between central and peripheral route factors on the quality of creative information. Finally, binary logistic regression was adopted to test the research hypotheses on the empirical data from Salesforce.FindingsThe results indicated that users with high extroversion, conscientiousness, social centrality and prior success rate tended to propose high-quality information. Meanwhile, information timeliness, readability and sentiment also negatively influence the quality of creative information.Originality/valueDifferent from previous studies, the study findings not only provide insights on identifying the quality of creative information from an information perspective, but also promotes the awareness of the intrinsic personality traits of information users and innovative support efforts by platforms and their managers.
The role of supervisor support for strengths use in promoting perceived employability and career satisfaction
Authors: Matsuo Makoto 
Published: July 2021

PurposeThis study aims to examine how perceived supervisor support for strengths use (PSSSU) directly and indirectly facilitates career satisfaction and perceived employability as mediated by strengths use behavior.Design/methodology/approachA two-wave questionnaire survey was administered to nurses (n = 221) and analyzed using structural equation modeling.FindingsResults indicated that PSSSU directly enhanced career satisfaction and indirectly enhanced perceived employability through strengths use behavior.Research limitations/implicationsAs the sample was limited to nurses in a Japanese hospital, it is possible that the characteristics of the national culture and occupation affected the results.Practical implicationsSupport for strengths use is important especially in stressful work environments in order to retain professional employees by enhancing their employability and career satisfaction.Originality/valueThis study extends the literature by identifying the different effects of PSSSU on the two types of career-related well-being. The present research is the first study to show the mediating role played by strengths use behavior in linking PSSSU to perceived employability.

Abstract

The extinction of 80% of megaherbivore (>1,000 kg) species towards the end of the Pleistocene altered vegetation structure, fire dynamics and nutrient cycling world‐wide. Ecologists have proposed (re)introducing megaherbivores or their ecological analogues to restore lost ecosystem functions and reinforce extant but declining megaherbivore populations. However, the effects of megaherbivores on smaller herbivores are poorly understood.

We used long‐term exclusion experiments and multispecies hierarchical models fitted to dung counts to test (a) the effect of megaherbivores (elephant and giraffe) on the occurrence (dung presence) and use intensity (dung pile density) of mesoherbivores (2–1,000 kg), and (b) the extent to which the responses of each mesoherbivore species was predictable based on their traits (diet and shoulder height) and phylogenetic relatedness.

Megaherbivores increased the predicted occurrence and use intensity of zebras but reduced the occurrence and use intensity of several other mesoherbivore species. The negative effect of megaherbivores on mesoherbivore occurrence was stronger for shorter species, regardless of diet or relatedness.

Megaherbivores substantially reduced the expected total use intensity (i.e. cumulative dung density of all species) of mesoherbivores, but only minimally reduced the expected species richness (i.e. cumulative predicted occurrence probabilities of all species) of mesoherbivores (by <1 species).

Simulated extirpation of megaherbivores altered use intensity by mesoherbivores, which should be considered during (re)introductions of megaherbivores or their ecological proxies. Species' traits (in this case shoulder height) may be more reliable predictors of mesoherbivores' responses to megaherbivores than phylogenetic relatedness, and may be useful for predicting responses of data‐limited species.
Invasion drives plant diversity loss through competition and ecosystem modification
Authors: Carboni Marta , Livingstone Stuart W. , Isaac Marney E. , Cadotte Marc W. 
Published: July 2021

Abstract

Although invasive plants increasingly contribute to the current biodiversity crisis, the mechanisms through which they impact native communities are still poorly understood. Community ecology theory has emphasized direct competitive displacement over common resources, but invasion‐driven ecosystem modifications, such as altered soil pH, might also have consequences for plant diversity. However, the relative importance of ecosystem modification compared to direct resource competition has rarely been tested.

Here we studied the invasive vine Vincetoxicum rossicum across invaded meadows in southern Ontario, Canada. In each meadow site, we quantified: (a) the strength of impact on the resident plant community, (b) the potential for competition with resident species (as the degree of niche dissimilarity and competitive superiority to the residents based on their functional traits) and (c) the amount of ecosystem modification related to invasion.

We found that impacts on plant biodiversity were more negative where the invader had greater potential to competitively displace species (because it had a similar niche as the residents or was competitively superior), but also where it strongly altered soil N pools, moisture and pH.

Synthesis. Our case study suggests that while competition is undoubtedly an important driver of invasion impact, ecosystem modifications can have cascading effects on plant communities, thereby magnifying the impacts of biological invasions.

SummaryPhage predation constitutes a major mortality factor for bacteria in aquatic ecosystems, and thus, directly impacts nutrient cycling and microbial community dynamics. Yet, the population dynamics of specific phages across time scales from days to months remain largely unexplored, which limits our understanding of their influence on microbial succession. To investigate temporal changes in diversity and abundance of phages infecting particular host strains, we isolated 121 phage strains that infected three bacterial hosts during a Baltic Sea mesocosm experiment. Genome analysis revealed a novel Flavobacterium phage genus harboring gene sets putatively coding for synthesis of modified nucleotides and glycosylation of bacterial cell surface components. Another novel phage genus revealed a microdiversity of phage species that was largely maintained during the experiment and across mesocosms amended with different nutrients. In contrast to the newly described Flavobacterium phages, phages isolated from a Rheinheimera strain were highly similar to previously isolated genotypes, pointing to genomic consistency in this population. In the mesocosm experiment, the investigated phages were mainly detected after a phytoplankton bloom peak. This concurred with recurrent detection of the phages in the Baltic Proper during summer months, suggesting an influence on the succession of heterotrophic bacteria associated with phytoplankton blooms.
A comprehensive review on polarity, partitioning, and interactions of phenolic antioxidants at oil–water interface of food emulsions
Authors: Farooq Shahzad , Abdullah  , Zhang Hui , Weiss Jochen 
Published: July 2021

AbstractThere has been a growing interest in developing effective strategies to inhibit lipid oxidation in emulsified food products by utilization of natural phenolic antioxidants owing to their growing popularity over the past decades. However, due to the complexity of emulsified systems, the inhibition mechanism of phenolic antioxidants against lipid oxidation is rather complicated and not yet fully understood. In order to highlight the importance of polarity of phenolic antioxidants in emulsified systems according to the polar paradox, this review covers the recent progress on chemical, enzymatic, and chemoenzymatic lipophilization techniques used to modify the polarity of antioxidants. The partitioning behavior of phenolic antioxidants at the oil–water interface, which can be influenced by the presence of synthetic surfactants and/or antioxidant emulsifiers (e.g., polysaccharides, proteins, and phospholipids), is discussed. In addition, the emerging phenolic antioxidants among phenolic acids, flavonoids, tocopherols, and stilbenes applied in food emulsions are elaborated. As well, the interactions of polar–nonpolar antioxidants are stressed as a promising strategy to induce synergistic interactions at oil–water interface for improved oxidative stability of emulsions.
Water‐soluble polymers in agriculture: xanthan gum as eco‐friendly alternative to synthetics
Authors: Berninger Teresa , Dietz Natalie , González López Óscar 
Published: July 2021

SummaryWater‐soluble polymers (WSPs) are a versatile group of chemicals used across industries for different purposes such as thickening, stabilizing, adhesion and gelation. Synthetic polymers have tailored characteristics and are chemically homogeneous, whereas plant‐derived biopolymers vary more widely in their specifications and are chemically heterogeneous. Between both sources, microbial polysaccharides are an advantageous compromise. They combine naturalness with defined material properties, precisely controlled by optimizing strain selection, fermentation operational parameters and downstream processes. The relevance of such bio‐based and biodegradable materials is rising due to increasing environmental awareness of consumers and a tightening regulatory framework, causing both solid and water‐soluble synthetic polymers, also termed ‘microplastics’, to have come under scrutiny. Xanthan gum is the most important microbial polysaccharide in terms of production volume and diversity of applications, and available as different grades with specific properties. In this review, we will focus on the applicability of xanthan gum in agriculture (drift control, encapsulation and soil improvement), considering its potential to replace traditionally used synthetic WSPs. As a spray adjuvant, xanthan gum prevents the formation of driftable fine droplets and shows particular resistance to mechanical shear. Xanthan gum as a component in encapsulated formulations modifies release properties or provides additional protection to encapsulated agents. In geotechnical engineering, soil amended with xanthan gum has proven to increase water retention, reduce water evaporation, percolation and soil erosion – topics of high relevance in the agriculture of the 21st century. Finally, hands‐on formulation tips are provided to facilitate exploiting the full potential of xanthan gum in diverse agricultural applications and thus providing sustainable solutions.
Optimizing sampling design and sequencing strategy for the genomic analysis of quantitative traits in natural populations

Published: July 2021

AbstractMapping the genes underlying ecologically relevant traits in natural populations is fundamental to develop a molecular understanding of species adaptation. Current sequencing technologies enable the characterization of a species’ genetic diversity across the landscape or even over its whole range. The relevant capture of the genetic diversity across the landscape is critical for a successful genetic mapping of traits and there are no clear guidelines on how to achieve an optimal sampling and which sequencing strategy to implement. Here we determine, through simulation, the sampling scheme that maximizes the power to map the genetic basis of a complex trait in an outbreeding species across an idealized landscape and draw genomic predictions for the trait, comparing individual and pool sequencing strategies. Our results show that quantitative trait locus detection power and prediction accuracy are higher when more populations over the landscape are sampled and this is more cost‐effectively done with pool sequencing than with individual sequencing. Additionally, we recommend sampling populations from areas of high genetic diversity. As progress in sequencing enables the integration of trait‐based functional ecology into landscape genomics studies, these findings will guide study designs allowing direct measures of genetic effects in natural populations across the environment.
