The Impact

Intensive conventional agriculture and climate change have induced severe ecological damages and threatened global food security, claiming a reorientation of agricultural management and public policies towards a more sustainable development model. In this context, nanomaterials promise to support this transition by promoting mitigation, enhancing productivity, and reducing contamination. This review gathers recent research innovations on smart nanoformulations and delivery systems improving crop protection and plant nutrition, nanoremediation strategies for contaminated soils, nanosensors for plant health and food quality and safety monitoring, and nanomaterials as smart food-packaging. It also highlights the impact of engineered nanomaterials on soil microbial communities, and potential environmental risks, along with future research directions. Although large-scale production and in-field testing of nano-agrochemicals are still ongoing, the collected information indicates improvements in uptake, use efficiency, targeted delivery of the active ingredients, and reduction of leaching and pollution. Nanoremediation seems to have a low negative impact on microbial communities while promoting biodiversity. Nanosensors enable high-resolution crop monitoring and sustainable management of the resources, while nano-packaging confers catalytic, antimicrobial, and barrier properties, preserving food safety and preventing food waste. Though, the application of nanomaterials to the agri-food sector requires a specific risk assessment supporting proper regulations and public acceptance.

The Impact

The knowledge of the survival of inoculated fungal and bacterial strains in field and the effects of their release on the indigenous microbial communities has been of great interest since the practical use of selected natural or genetically modified microorganisms has been developed. Soil inoculation or seed bacterization may lead to changes in the structure of the indigenous microbial communities, which is important with regard to the safety of introduction of microbes into the environment. Many reports indicate that application of microbial inoculants can influence, at least temporarily, the resident microbial communities. However, the major concern remains regarding how the impact on taxonomic groups can be related to effects on functional capabilities of the soil microbial communities. These changes could be the result of direct effects resulting from trophic competitions and antagonistic/synergic interactions with the resident microbial populations, or indirect effects mediated by enhanced root growth and exudation. Combination of inoculants will not necessarily produce an additive or synergic effect, but rather a competitive process. The extent of the inoculation impact on the subsequent crops in relation to the buffering capacity of the plant-soil-biota is still not well documented and should be the focus of future research.

AbstractWhile soil erosion drives land degradation, the impact of erosion on soil microbial communities and multiple soil functions remains unclear. This hinders our ability to assess the true impact of erosion on soil ecosystem services and our ability to restore eroded environments. Here we examined the effect of erosion on microbial communities at two sites with contrasting soil texture and climates. Eroded plots had lower microbial network complexity, fewer microbial taxa, and fewer associations among microbial taxa, relative to non-eroded plots. Soil erosion also shifted microbial community composition, with decreased relative abundances of dominant phyla such as Proteobacteria, Bacteroidetes, and Gemmatimonadetes. In contrast, erosion led to an increase in the relative abundances of some bacterial families involved in N cycling, such as Acetobacteraceae and Beijerinckiaceae. Changes in microbiota characteristics were strongly related with erosion-induced changes in soil multifunctionality. Together, these results demonstrate that soil erosion has a significant negative impact on soil microbial diversity and functionality.

PurposeThis paper examines the empirical research on police reassurance following a collective trauma event (CTE).Design/methodology/approachUsing a scoping review methodology, this paper sought to establish the extent, range and nature of published literature on policing responses to collective traumatic events, and to identify key features of this form of direct practice. Included papers needed to focus on police responses oeassurance with the public related to events (pre-or post) that could be regarded as collective trauma events by nature or scale. Searches were conducted using the Web of Science, SCOPUS and PsychINFO databases for literature published between January 2000 and December 2019.FindingsFourteen articles met the inclusion criteria. The key themes identified: (1) measuring the impact of reassurance and community policing; (2) community attitudes to policing and social disorder/critical events; (3) police workforce responses to traumatic events; and (4) interventions to support police to respond to their community.Research limitations/implicationsFuture research needs to examine the elements that create a robust organisational infrastructure that can withstand the demands of policing in ordinary and extraordinary times. Fundamental to the studies in this review is the relationship between the police agencies and the community. The nature of this relationship and how it can be strengthened to ameliorate the negative impact of CTEs in communities needs further exploration.Originality/valueThis paper provides important findings that can inform future reassurance policing practice and research.

Structure and diversity of microbial communities are an important research topic in biology, since microbes play essential roles in the ecology of various environments. Different DNA isolation protocols can lead to data bias and can affect results of next-generation sequencing. To evaluate the impact of protocols for DNA isolation from soil samples and also the influence of individual handling of samples, we compared results obtained by two researchers (R and T) using two different DNA extraction kits: (1) MO BIO PowerSoil® DNA Isolation kit (MO_R and MO_T) and (2) NucleoSpin® Soil kit (MN_R and MN_T). Samples were collected from six different sites on Okinawa Island, Japan. For all sites, differences in the results of microbial composition analyses (bacteria, archaea, fungi, and other eukaryotes), obtained by the two researchers using the two kits, were analyzed. For both researchers, the MN kit gave significantly higher yields of genomic DNA at all sites compared to the MO kit (ANOVA; P <0.006). In addition, operational taxonomic units for some phyla and classes were missed in some cases: Micrarchaea were detected only in the MN_T and MO_R analyses; the bacterial phylum Armatimonadetes was detected only in MO_R and MO_T; and WIM5 of the phylum Amoebozoa of eukaryotes was found only in the MO_T analysis. Our results suggest the possibility of handling bias; therefore, it is crucial that replicated DNA extraction be performed by at least two technicians for thorough microbial analyses and to obtain accurate estimates of microbial diversity.

The Impact

Consumer participation typically reduces consumer skepticism and leads to a positive response to corporate social responsibility (CSR) activities. Although many companies are encouraging consumers to participate in CSR activities, there is still insufficient research on the effectiveness of this strategy. That is, prior studies do not provide guidelines on the effectiveness of requiring consumers to participate in CSR activities. We examine the impact of the required participation effort on CSR participation intention, focusing on the differences in consumers’ perception of a warm glow feeling and costs according to their construal level. For this study, 107 participants were recruited using Amazon Mechanical Turk. We tested hypotheses using a 2 (CSR participation effort) × 2 (construal level) between-subject analysis of variance (ANOVA), planned contrast analysis, and mediation analysis. The results indicate that for consumers with high construal levels who perceive participation efforts as warm glow, participation efforts have a positive impact on CSR participation intention. However, for those with low construal levels who perceive participation efforts as costs, high required efforts have a negative impact on their participation intention. Finally, we discuss the implications of these results, discuss the limitations, and suggest future research directions.

The Impact

Soil properties determining the thermal transmissivity, the heat duration and temperatures reached during soil heating are key factors driving the fire-induced changes in soil microbial communities. The aim of the present study is to analyze, under laboratory conditions, the impact of the thermal shock (infrared lamps reaching temperatures of 100 °C, 200 °C and 400 °C) and moisture level (0%, 25% and 50% per soil volume) on the microbial properties of three soil mixtures from different sites. The results demonstrated that the initial water content was a determinant factor in the response of the microbial communities to soil heating treatments. Measures of fire impact included intensity and severity (temperature, duration), using the degree-hours method. Heating temperatures produced varying thermal shock and impacts on biomass, bacterial activity and microbial community structure.
