Culture Dependent

Fraxinus excelsior populations are in decline due to the ash dieback disease Hymenoscyphus fraxineus. It is important to understand genotypic and environmental effects on its fungal microbiome to develop disease management strategies. To do this, we used culture dependent and culture independent approaches to characterize endophyte material from contrasting ash provenances, environments, and tissues (leaves, roots, seeds). Endophytes were isolated and identified using nrITS, LSU, or tef DNA loci in the culture dependent assessments, which were mostly Ascomycota and assigned to 37 families. Few taxa were shared between roots and leaves. The culture independent approach used high throughput sequencing (HTS) of nrITS amplicons directly from plant DNA and detected 35 families. Large differences were found in OTU diversity and community composition estimated by the contrasting approaches and these data need to be combined for estimations of the core endophyte communities. Species richness and Shannon index values were highest for the leaf material and the French population. Few species were shared between seed and leaf tissue. PCoA and NMDS of the HTS data showed that seed and leaf microbiome communities were highly distinct and that there was a strong influence of Fraxinus species identity on their fungal community composition. The results will facilitate a better understanding of ash fungal ecology and are a step toward identifying microbial biocontrol systems to minimize the impact of the disease.

The Impact

Purpose The purpose of this paper is to analyse the impact of high-speed railway (HSR) on industrial pollution emissions using the data for 285 prefecture-level cities in China from 2004 to 2016. Design/methodology/approach The research method used in this paper is the multi-period difference-in-differences (DID) model, which is an effective policy effect assessment method. To further address the issue of endogeneity, the DID integrated with the propensity score matching (PSM-DID) approach is employed to eliminate the potential self-selection bias. Findings The results show that the HSR has significantly reduced industrial pollution emissions, which is validated by several robustness tests. Compared with peripheral cities, HSR exerts a greater impact on industrial pollution emissions in central cities. In addition, the mechanism test reveals that the optimised allocation of inter-city industries is an important channel for HSR to mitigate industrial pollution emissions, and this is closely related to the location of HSR stations. Originality/value Previous studies have paid more attention to evaluating the economic effects of HSR, however, most of these studies overlook its environmental effects. Consequently, the impact of HSR on industrial pollution emissions is led by using multi-period DID models in this paper, in which the environmental effects are measured. The results of this paper can provide a reference for the pollution reduction policies and also the coordinated development of economic growth and environmental quality.

AbstractParasitoids are significant enemies of many economically important insects and there is some evidence to suggest that their actions have a role in terminating the outbreaks of forest Lepidoptera populations. In this study, we examined the impact of parasitoids on the pupae of the pine processionary moth, and highlighted the presence of several parasitoid species for this developmental stage. A higher rate of parasitism was found when the pupal density in the soil was reduced, but the rate of parasitism was not influenced by pupal morphological traits or by the presence or absence of a cocoon around a pupa. Of the external factors examined, a delay in the time of descent of larvae from the trees had a positive effect on the level of parasitism. Observational data indicated that dipteran and hymenopteran were the most abundant parasitoids to emerge from moth pupae. Our study highlights the complexity of the parasitoid–host dynamics, and stresses the importance of carefully determining environmental effects on host–parasitoid relations.

AbstractThis current study investigates the use of online role-playing, in an online discussion forum, in learning the community of inquiry framework – an area of learning covered in the Computer-Aided Instruction (CAI) course, an elective course for Computer Science undergraduate students at Universitas Indonesia. The participants were divided into different roles. Each group was triggered to discuss the implementation of online collaborative learning. A mixed-methods approach was utilised to analyse the qualitative and quantitative data. The result of content analysis exhibited students implementing all the components of the CoI framework. Teaching presence was the rarest, as students were focused on delivering their ideas. Social presence appeared in almost all messages since it is the easiest, and students can feel the impact immediately. The discussion moved to the integration phase but did not proceed to resolution. This study suggested some recommendations and future research topics.

PurposeThis study investigates how Danmu (danmaku) technological features (DTFs) of recommendation vlogs (rec-vlogs) impact consumer experiences and decisions.Design/methodology/approachThe authors adopt the partial least squares structural equation modeling (PLS-SEM) technique with a sample of 422 viewers of Danmu-enabled rec-vlogs to examine the proposed model.FindingsThe DTFs positively affect consumer loyalty intentions through the mediation of social presence and immersion. Also, vlogger-product congruency significantly moderates the relationship between social presence and immersion.Originality/valueWith the increasing popularity of vlogs, retailers have adopted the vlog as a new marketing channel to connect with consumers. Although a growing body of studies focuses on this phenomenon, little is known about how DTFs help to increase consumer loyalty toward using rec-vlogs as product information sources. Anchored on the stimulus–organism–response framework, this study investigates how pseudo-synchronicity, Danmu-content congruency and parallelism, three DTFs used in rec-vlogs, impact consumer experiences of social presence and immersion, eventually influence the consumers' loyalty intentions toward rec-vlogs. The authors also examine whether the effect of social presence on immersion is contingent on vlogger-product congruency. These findings have implications for both researchers and practitioners to understand the effect of DTFs in the context of rec-vlogs.

The Impact

The focus in this study is on the effect on Chinese consumers’ intention to purchase proenvironmental products of 3 types of marketing information: environmental knowledge relating to a product, information about corporate social responsibility, and descriptive norms about environmental protection. I also examined the impact of social presence on the consumers’ intention to purchase. I conducted 2 laboratory experiments with 723 participants and findings indicate that each of the 3 kinds of marketing information and social presence had a significantly positive effect on participants’ purchase intention, and the effect of marketing information on corporate social responsibility and environmental knowledge was weakened when consumers made the decision with social presence. The findings expand research on marketing information of proenvironmental products and provide insight into the effect of social presence. Suggestions are made for the government and manufacturing managers that may increase Chinese consumer purchase of proenvironmental products.

Since the adoption of the EU's first Sustainable Development Strategy in 2001, the European Commission has been committed to undertaking impact assessments of its major policy proposals, covering the potential positive and negative economic, social and environmental effects both inside and outside the European Union. This paper provides as evaluation of a sample of the Commission's recent EC Impact Assessments, focusing on the extent to which the goal of sustainable development has been integrated into the impact assessment analysis.
