Does unified theory of acceptance and use of technology (UTAUT) reduce resistance and anxiety of individuals towards a new system?
Authors: Donmez-Turan Aygul 
Published: August 2019

Purpose
Technology acceptance is an incremental approach that has developed over the years. Taking technology acceptance or adoption literature into consideration, the paper aims to investigate the mediating role of adoption readiness, constructed on the basis of the unified theory of acceptance and use of technology (UTAUT), on the relationship between user resistance as well as user anxiety and attitude toward using a system.

Design/methodology/approach
In consideration of previous studies, the public personnel’s adaptation of electronic document management systems is within the scope of the present research. Gathering data from 262 administrative personnel working in a public university, explanatory and second-order confirmatory factor analyses were done for the UTAUT scale. In addition, reliability and construct validity were tested for each scale; UTAUT, user resistance, user anxiety and attitude toward using. Relationships among variables of the research were controlled by the measurement model and then the structural model was tested.

Findings
Confirming previous research, the scales of UTAUT, user resistance, user anxiety and attitude toward using were found to have acceptable reliability and internal consistency. In addition, the implications of the paper showed user resistance influenced attitude toward using indirectly, by affecting adoption readiness. It also indicated that adoption readiness fully mediated the relationship between user anxiety and attitude toward using.

Originality/value
Negative behavioral antecedents of UTAUT are the focus of the paper. Reducing the negative effects of resistance as well as anxiety of individuals on their attitudes using a system is emphasized in the technology acceptance literature. Furthermore, defining each dimension of UTAUT as a single construct, adoption readiness, and proving the intervening role of adoption readiness between user resistance, as well as anxiety, on the attitude toward using a system are contributions to the literature.

Authors: Ren Xu , Yan Zi , Wang Zhaojing , He Jingwen 
Published: August 2019

Purpose
Numerous studies highlight the importance of knowledge transfer between projects, but the influence factors are still debated. As a contribution to the identified gap, the purpose of this paper is to investigate the role of organizational context, project characteristics and social relations in the inter-project knowledge transfer within the project-based organizations (PBOs).

Design/methodology/approach
This paper collects the data through 268 sample questionnaires from Chinese construction sectors and applies the structure equation modeling to analyze knowledge transfer between projects in PBOs.

Findings
The results indicate the organizational context (meeting system, reward system and shared culture) and project characteristics (similarity and urgency) are antecedents affecting social relations (communication, trust and reciprocity) between project teams, and their social relations further influence the effectiveness of inter-project knowledge transfer.

Originality/value
The study highlights the role of organizational context and effect of social relations for inter-project knowledge transfer in PBOs, and provides valuable suggestions for knowledge and project management in PBOs.
The disruptive and transformative potential of new technologies for accounting, accountants and accountability
Authors: Marrone Mauricio , Hazelton James 
Published: August 2019

PurposeThis paper aims to explore the extent to which technology and disruption has been considered within the accounting literature, to introduce the five papers which compose this special issue and to provide an agenda for future research on technology and disruption.Design/methodology/approachTo explore previous works on the disruptive potential of technology in accounting, the study compares topics in accounting research articles that contain variations of the term “disrupt” with those articles containing variations of the term “technology”. Based on the method first proposed in Marrone and Hammerle (2016), an entity linker application was used to extract key topics from the top 50 accounting journals, and these topics were then compared to determine the extent of thematic intersection.FindingsA key finding is that accounting academic articles featuring “disruption” are rarely linked with “technology”. The concept of “disruption” has been largely synonymous with crisis, and the crises endured to date have had predominantly social or environmental causes (e.g. the GFC and natural disasters). The literature on technology has coalesced around three broad themes – creation, deployment and protection – which have not been identified as crises triggers so far. This finding underscores the importance of the papers comprising this special issue, which explore enhanced data visualisation, blockchain and social media, as well as considering how such technologies might be managed and their potential for either emancipation or enslavement.Research limitations/implicationsIn relation to the review of prior literature, the primary limitation is that a quantitative approach was taken. Whilst this allows for a greater sample size and replication, a qualitative thematic review may reveal additional findings. The primary implication of this research and this special issue collectively is that there is much more to be done in exploring both the potential benefits and limitations of new technologies for accounting.Originality/valueIn relation to the review of prior literature, no previous studies have undertaken a quantitative analysis of the intersection of technology disruption in accounting research. In relation to this special issue, these papers collectively provide a multi-faceted view of how technology can and will transform the practice and potential of accounting in the years ahead. Finally, the provision of a thematic framework and research agenda will assist future researchers in exploring this dynamic and important field.

Authors: Chen Ming-Huei , Krishna Shwetha M. , Yu Chan-Yuan 
Published: August 2019

PurposeBuilding on the conservation of resource theory, the authors posit work-life support as an essential resource for middle managers. This paper aims to explore the positive association between work-life support, positive emotion, job satisfaction and happiness. The paper also assesses the moderating role of work pressure on work-life support and positive emotion relationship on the one hand and flextime on positive emotion and job satisfaction on the other.Design/methodology/approachData collected from 512 middle managers of small and medium-sized firms including manufacturing, service and finance sectors in Taiwan were used to test the hypotheses.FindingsThe results reveal that work pressure strengthens the effect of work-life support on positive emotions, whereas time flexibility weakens the effect of positive emotion on job satisfaction. Work-life support positively influences happiness through the intervening variables of positive emotion and job satisfaction.Practical implicationsThe paper highlights the importance of creating a positive work environment, as empowering middle managers with work-life support can help them handle work pressure and work-life conflict. The negative influence of flextime on positive emotion and job satisfaction highlights the need for effective handling of flextime.Originality/valueThis paper examines the work-life support and happiness of middle managers in the Chinese cultural context which has been under-explored. This paper expands the external validity of previous research results of Western samples by finding the positive influence of work pressure on work-life fit and positive emotion and negative influence of flextime on positive emotion and job satisfaction link.

Authors: Dave Harshit K. , Prajapati Ashish R. , Rajpurohit Shilpesh R. , Patadiya Naushil H. , Raval Harit K. 
Published: August 2019

Purpose
Fused deposition modeling (FDM) is being increasingly used in automotive and aerospace industries because of its ability to produce specimens having difficult geometrical shape. However, owing to lack of critical information regarding the reliability and mechanical properties of FDM-printed parts at various designs, the use of 3D printed parts in these industries is limited. Therefore, the purpose of this paper is to investigate the impact of process parameters of FDM on the tensile strength of open-hole specimen printed using in-house-fabricated polylactic acid (PLA).

Design/methodology/approach
In the present study, three process parameters, namely, raster angle, layer thickness and raster width, are selected for investigation of tensile strength. To produce the tensile specimens in the FDM machine, the PLA filament is used which is fabricated from PLA granules using a single-screw extruder. Further, the experimental values are measured and critically analysed. Failure modes under tests are studied using scanning electron microscopy (SEM).

Findings
Results indicate that the raster angle has a significant effect on the tensile strength of open-hole tensile specimen. Specimens built with 0° raster angle, 200-µm layer thickness and 500-µm raster width obtained maximum tensile strength.

Originality/value
In this work, a new concept of testing a plate that has a rectangular shape and a circular hole at the centre is tested. Open-hole tensile test standard ASTM D5766 has been implemented for the first time for the FDM process.
Organizational unlearning: the challenges of a developing phenomenon
Authors: Becker Karen 
Published: August 2019

Purpose
This paper aims to provide a synthesis of the contributions to this special issue focusing on organizational unlearning.

Design/methodology/approach
The papers were examined in depth to identify the key contributions and areas of ongoing concern for those researching unlearning.

Findings
Each paper was noted as making a unique contribution to the unlearning debate, and the authors’ understanding of this critical issue, however, areas of divergence or contradiction remain. Although the special issue called for a range of disciplines to engage with the topic, it is clear that some disciplines and contexts have embraced the concept of unlearning more than others, and that there are some key issues that remain problematic for advancing research of this phenomenon. Two key imperatives include clarifying and aligning terminology and advancing stronger underpinning empirical research of unlearning.

Originality/value
The paper identifies the current contradictions and questions relating to organizational unlearning and argues that it is time for clarity and more empirical research about this critical topic.

Published: August 2019

Abstract

Forest responses to changes in drought frequency is a critical matter for the future of Amazon forests under climate change, but equally important is the much less studied response to large floods, which may also increase tree mortality and change forest functionality. Further, forest vulnerability to flood is being exacerbated by large hydroelectric dams on Amazon rivers that put upland environments not adapted to flood at unique risk.

To address this critical knowledge gap, we evaluated the effects of the extreme 2014 rainfall coupled with the newly constructed Jirau hydroelectric dam on tree survival and forest functionality, in the upper Madeira River basin. We used surveys of campinarana white‐sand forests (stems >1 cm in seven 1 ha plots) conducted before and after the extreme flood to test trait‐based ecological theory predictions of the impact of flood on overall community function.

We found that flooding increased mortality by nearly five‐fold (from 3.2% to 15.1%), mostly in smaller trees. This large mortality induced significant and consistent shifts in community function, towards species with conservative life strategies: direct comparison of trait differences between surviving and dying trees showed that survivors had smaller, high density stomata, and higher leaf dry matter content, wood density and root tissue density (RTD). Size and density of stomata and RTD were the most important predictors of species mortality rates.

Synthesis and applications. Although focused on a single event in one type of forest, this work highlights the general importance, and need for further study, of interaction between climate change and mega‐dams in Amazon forests. In particular, we expect that continued expansion of hydroelectric dams in Amazonia will likely intensify the impact of large floods on forests made newly vulnerable by these dams, with substantial effect on future forest functionality in expanded floodplain areas across the Basin. Hence, these interaction analyses should be required in the Brazilian legal instruments such as the environmental impact assessments and its accompanying Environmental Impacts Reports for large infrastructure projects in Amazon.

Published: August 2019

AbstractPlacental growth factor (PlGF) is decreased in early gestation of pregnant women who subsequently develop pre‐eclampsia. In this study, pre‐emptive treatment with PlGF to prevent pre‐eclampsia was evaluated in an in vivo rodent model of experimental pre‐eclampsia (EPE) induced by TNF‐α and in an in vitro model of human first‐trimester trophoblast invasion. Pregnant C57/BL6 mice were treated with recombinant mouse placental growth factor‐2 (rmPlGF‐2) 100 μg/kg/day IP from gestational day (gd) 10. Animals had EPE induced by continuous TNF‐α infusion on gd 13 and were subject to either continuous blood pressure monitoring by radiotelemetry throughout pregnancy or live placenta T2‐weighted magnetic resonance imaging (MRI) to demonstrate placental function on gd 17. There was no difference in BP (P > .99), proteinuria (P = .9) or T2 values on MRI (P = .9) between control and rmPlGF‐2‐treated animals. On gd 13, animals treated with rmPlGF‐2 demonstrated increased placenta PlGF (P = .01) and Toll‐like receptor‐3 (P = .03) mRNA expression as compared with controls. Fluorescent‐labelled human uterine microvascular endothelial cells and HTR8/SVNeo cells were co‐cultured on Matrigel™ and treated with recombinant human PlGF (rhPlGF) (10 ng/mL) and/or TNF‐α (0.5 ng/mL). Trophoblast integration into endothelial networks was reduced by added TNF‐α (P = .006), as was rhPlGF concentration in conditioned media (P < .0001). Cell integration was not ameliorated by addition of rhPlGF (P > .9). Although TNF‐α‐induced EPE was not reversed with pre‐emptive rmPlGF‐2, a further trial of pre‐emptive rhPlGF in vivo is required to determine whether the absence of effect of rhPlGF demonstrated in vitro precludes PlGF as a preventative therapy for pre‐eclampsia.

Published: August 2019

AbstractThe structure and abundance of winter planktonic communities are limited by environmental conditions that are unfavorable to life, but do not stop biological processes. The aim of the study was to test the hypothesis that the abundance of planktonic groups of organisms in temperate lakes can be higher during winter under ice cover than during the ice‐free seasons. Physical (ice/snow cover, temperature), chemical (organic carbon, chlorophyll a, phosphorus, nitrogen) and biological parameters (phytoplankton, protozooplankton, zooplankton) were investigated in three eutrophic lakes during two consecutive years in winter, spring, summer and autumn. The results of this study showed that in all lakes chlorophyll a concentrations were usually lower in winter than in other seasons, while total nitrogen concentrations were higher in winter than in autumn. All groups of planktonic organisms were able to reach similar or even higher abundances in winter under‐ice than in other ice‐free periods, depending on the lake morphometry and the year of the study. Winter taxonomic structure of phytoplankton was similar to the spring (medium‐sized Lake Dgał Wielki with the dominance of cryptophytes), summer (small‐sized Lake Dgał Mały with cyanobacteria as a dominant group) or autumn (the shallow lake with the dominance of diatoms) structure, depending on the lake. In all lakes, the structure of the ciliate community was the most similar to that of the spring with the clear dominance of Oligotrichida. Our results show that some species among all the studied groups of organisms can lead an active and dynamic life under the ice cover.
Metatranscriptomic and metabolite profiling reveals vertical heterogeneity within a Zygnema green algal mat from Svalbard (High Arctic)

Published: August 2019

SummaryWithin streptophyte green algae Zygnematophyceae are the sister group to the land plants that inherited several traits conferring stress protection. Zygnema sp., a mat‐forming alga thriving in extreme habitats, was collected from a field site in Svalbard, where the bottom layers are protected by the top layers. The two layers were investigated by a metatranscriptomic approach and GC–MS‐based metabolite profiling. In the top layer, 6569 genes were significantly upregulated and 149 were downregulated. Upregulated genes coded for components of the photosynthetic apparatus, chlorophyll synthesis, early light‐inducible proteins, cell wall and carbohydrate metabolism, including starch‐degrading enzymes. An increase in maltose in the top layer and degraded starch grains at the ultrastructural levels corroborated these findings. Genes involved in amino acid, redox metabolism and DNA repair were upregulated. A total of 29 differentially accumulated metabolites (out of 173 identified ones) confirmed higher metabolic turnover in the top layer. For several of these metabolites, differential accumulation matched the transcriptional changes of enzymes involved in associated pathways. In summary, the findings support the hypothesis that in a Zygnema mat the top layer shields the bottom layers from abiotic stress factors such as excessive irradiation.

Published: August 2019

AbstractThe imminent nanotechnology and progressive instrumentations together have vast applications in the field of forensic science. Few prominent examples are gold nanoparticles for improvising the efficiency of polymerase chain reaction and atomic force microscopy for examining ink and bloodstains. Characteristics like distinct ridge details of fingerprints could be obtained by applying different nanoparticles such as silver, zinc oxide, silicon dioxide, aluminum oxide, gold (with silver physical developer), europium, fluorescent carbon, and amphiphilic silica on a range of object surfaces, and among all, gold is most commonly used. Fingerprint is considered noteworthy evidence in any crime scene, and nano‐based techniques hold immense future potential in fingerprint investigations. Therefore, this paper focuses on the applications of nanoparticles in developing and detecting the latent fingerprints.
A global invasion by the thrip, Frankliniella occidentalis: Current virus vector status and its management

Published: August 2019

AbstractWestern flower thrip, Frankliniella occidentalis (Pergande), is among the most economically important agricultural pests globally, attacking a wide range of vegetable and horticultural crops. In addition to causing extensive crop damage, the species is notorious for vectoring destructive plant viruses, mainly belonging to the genera Orthotospovirus, Ilarvirus, Alphacarmovirus and Machlomovirus. Once infected by orthotospoviruses, thrips can remain virulent throughout their lifespan and continue transmitting viruses to host plants when and wherever they feed. These irruptive viral outbreaks in crops will permanently disrupt functional integrated pest management systems, and typically require a remedial treatment involving insecticides, contributing to further development of insecticide resistance. To mitigate against this continuing cycle, the most effective management is early and comprehensive surveillance of the pest species and recognition of plant viruses in the field. This review provides information on the pest status of F. occidentalis, discusses the current global status of the viruses vectored by this thrip species, examines the mechanisms involved in transmitting virus‐induced diseases by thrips, and reviews different management strategies, highlighting the potential management tactics developed for various cropping systems. The early surveillance and the utilization of potential methods for control of both F. occidentalis and viruses are proposed.
