Optimal Filters for ERP Research I: A General Approach for Selecting Filter Settings
Authors: Zhang Guanghui , Garrett David R. , Luck Steven J. 
Published: May 2023

AbstractFiltering plays an essential role in event-related potential (ERP) research, but filter settings are usually chosen on the basis of historical precedent, lab lore, or informal analyses. This reflects, in part, the lack of a well-reasoned, easily implemented method for identifying the optimal filter settings for a given type of ERP data. To fill this gap, we developed an approach that involves finding the filter settings that maximize the signal-to-noise ratio for a specific amplitude score (or minimizes the noise for a latency score) while minimizing waveform distortion. The signal is estimated by obtaining the amplitude score from the grand average ERP waveform (usually a difference waveform). The noise is estimated using the standardized measurement error of the single-subject scores. Waveform distortion is estimated by passing noise-free simulated data through the filters. This approach allows researchers to determine the most appropriate filter settings for their specific scoring methods, experimental designs, subject populations, recording setups, and scientific questions. We have provided a set of tools in ERPLAB Toolbox to make it easy for researchers to implement this approach with their own data.
A role for DNA methylation in bumblebee morphogenesis hints at female-specific developmental erasure

Published: May 2023

AbstractEpigenetic mechanisms, such as DNA methylation, are crucial factors in animal development. In some mammals almost all DNA methylation is erased during embryo development and re-established in a sex- and cell-specific manner. This erasure and re-establishment is thought to primarily be a vertebrate-specific trait. Insects are particularly interesting in terms of development as many species often undergo remarkable morphological changes en route to maturity, i.e. morphogenesis. However, little is known about the role of epigenetic mechanisms in this process across species. We have used whole genome bisulfite sequencing to track genome-wide DNA methylation changes through the development of an economically and environmentally important pollinator species, the bumblebee Bombus terrestris. We find overall levels of DNA methylation vary throughout development and we find developmentally relevant differentially methylated genes throughout. Intriguingly, we have identified a depletion of DNA methylation in ovaries and an enrichment in sperm. We suggest this could represent a sex-specific DNA methylation erasure event. To our knowledge this is the first suggestion of possible developmental DNA methylation erasure in an insect species. This study lays the required groundwork for functional experimental work to determine if there is a causal-nature to the DNA methylation differences identified. Additionally, the application of single-cell methylation sequencing to this system will enable more accurate identification of when/if DNA methylation is erased during development.
Assessing the role of institutional effectiveness on carbon sequestration: the case of China's nature reserve policy
Authors: Chen Yuquan , Fiankor Dela-Dem Doe , Kang Kuan , Zhang Qian 
Published: May 2023

PurposeCarbon storage in protected land is a practical climate stabilization strategy. It is increasingly being recognized as an essential means of safeguarding biomass carbon and improving local ecological conditions. Yet, increasing soil carbon sequestration by setting aside nature reserves does not depend only on the scale of the reserve but more so on the implementation and enforcement of the reserve protection policy. This paper aims to discuss the aforementioned issues.Design/methodology/approachThe authors show how nature reserves established and managed by different administrative levels affect carbon sequestration. Empirically, the authors estimate a time-varying difference-in-difference model that exploits China's distinct four-layered hierarchical nature reserve management system at the county level.FindingsThe findings show that higher administrative level (i.e. national and provincial) nature reserves have no effects on the carbon dynamic. However, reserves managed by lower administrative levels (i.e. prefecture- and county-level) are associated with reduced carbon sequestration. The results imply local governments fail to fulfil their responsibilities for nature reserves protection, leading to increased extractive activities and declined ecological biomass. Research limitations/implicationsResponsibility and accountability mechanisms for the violation of the nature reserves requirements need to be stipulated accordingly. Greater emphasis should be placed on nature reserves at the base level. The central government should continue efforts toward the establishment of ad hoc and independent management agencies at the ground-management level that are free of influence from base-level governments.Originality/valueThe heterogeneity in the performance of nature reserves across administrative levels confirms that ecosystem service quality is highly dependent on establishment, management and supervision. This provides a better understanding of the socio-ecological interdependence of protected areas.
The tail that wags the dog: lessons from the UK's independent unions for class struggle trade unionism
Authors: Weghmann Vera 
Published: May 2023

PurposeThis article examines in what way strategies of new independent trade unions in London – that achieved pioneering, victories to end outsourcing – offer learning opportunities for more established trade unions. It proposes to (re-)encourage a culture of class struggle trade unionism. The article builds on existing research that outlined the organising practices of these independent trade unions but breaks down the binary analysis of independent versus established trade unions. The author uses the acronym CARE (Collectivising individual grievances, Action, Relations of trust and care, Escalating confrontations) as an analytical framework for exploring class struggle trade unionism, and examines in what ways these strategies have been (re)-learnt by established trade unions through the example of independent trade unions. In doing so, this article contributes to a much wider debate on trade union renewal.Design/methodology/approachThis article offers an insider perspective of an “academic activist” (Chatterton et al., 2007). The article draws on author’s experiences and reflection as the co-founder of the trade union United Voices of the World (UVW) created in 2014, and previously involvement in the establishment of the Independent Workers of Great Britain (IWGB) in 2012. Findings are based on author’s ethnographic engagement as well as a selection of 29 interviews from a much larger data set on independent trade unions comprising focus groups and interviews.FindingsThis article demonstrates that class struggle trade unionism has in some ways been remembered and hence pioneered by the new independent trade unions, yet they are possible in established trade unions alike.Originality/valueThis is the first time an article systematically explores the strategies that established trade unions can learn – and indeed are learning – from independent trade unions.

Published: May 2023

PurposeThe purpose of this study is to clarify the role of various levels of modality richness [text-visual, audiovisual and augmented reality interactive technology (ARIT)] on vivid memories (visual sensory detailed, emotionally intense, first-person perspective and coherent) and exploratory behavior. To clarify which modality richness online retailers use is more appropriate to create a virtual reality simulation experience to fill a significant gap in the sensory interactive marketing paradigm.Design/methodology/approachA task-based laboratory study was conducted to provide users with private try-on space. A total of 429 valid questionnaires were collected, and partial least squares path modeling was adopted to test hypotheses.FindingsThe results indicate that various levels of modality richness (text-visual, audiovisual and ARIT) positively affect vivid memories (visual sensory detailed, emotionally intense, first-person perspective and coherent), and vivid memories successfully induce exploratory behavior.Practical implicationsThe study results could also help retailers and brands with clear guidance in designing and creating simulation experience services and choosing the best way to present products. With the results of this research, retailers will also be able to grasp better the critical points of introducing innovative technology into the service experience and then create the benefits of digital economic growth.Originality/valueExploring which digital interactive technology online retailers use is more appropriate to create a virtual reality shopping experience to fill a significant gap in the sensory interactive marketing paradigm. Exploring the antecedents of vivid memories in a digital sensory interactive experience contributes to the body schema literature and the script theory. We draw from construal level theory (CLT) to clarify the impact of various levels of modality richness on driving the difference in sensory simulation schema to break through the limited findings of previous studies, namely using CLT to interpret psychological distance.
Life strategies and metabolic interactions of core microbes during thiosulphate‐based denitrification

Published: May 2023

AbstractSulphur‐driven denitrification is a low‐cost process for the treatment of nitrate‐contaminated water. However, a comprehensive understanding of core populations and microbial interactions of a sulphur‐based denitrifying system is lacking. This study presents results from three replicated denitrifying systems amended with thiosulphate and operated under a low C/N ratio. Amplicon sequencing revealed gradual enrichments of a few abundant denitrifiers. Based on genome‐centred metagenomics and metatranscriptomics, a core set of microbes was identified in the systems, with Pseudomonas 1 and Thauera 2 being the most abundant ones. Although the replicates showed different enrichments, generalized observations were summarized. Most core populations conserved energy from denitrification coupled with sulphur. Pseudomonas 1 and Thauera 2 were able to finish complete denitrification. Surprisingly, they were also able to synthesize almost all amino acids and vitamins. In contrast, less abundant members, including Pseudomonas 2, were relatively auxotrophic and required an exogenous supply of amino acids and vitamins. The high expression of enzymes involved in biosynthesis and transport systems indicated their syntrophic relationships. The genomic findings suggested life strategies and interactions of the core thiosulphate‐based denitrifying microbiome, with implications for nitrate‐polluted water remediation.
Influence of capitalisation and presence of an article in noun phrase recognition in German: Evidence from eye‐tracking

Published: May 2023

BackgroundGerman is exceptional in its use of noun capitalisation. It has been suggested that sentence‐internal capitalisation as in German may benefit processing by specifically marking a noun and thus a noun phrase (NP). However, other cues, such as a determiner, can also indicate an NP. The influence of capitalisation on processing may thus be context‐dependent, that is, dependent on other cues. Precisely this context dependency is investigated in the current study: Is there an effect of capitalisation on reading and is this affected by the presence of other cues such as a determiner (specifically, an article)?MethodsWe ran an eye‐tracking study with 30 German‐speaking adults, measuring fixations during sentence reading. Critical NPs either contained correctly capitalised nouns or not and were presented either with or without a determiner.ResultsThe results show that both the presence of capitalisation on the noun and the presence of a determiner led to faster reading. When no determiner was present to signal the NP, the presence of noun capitalisation aided reading most.ConclusionsFrom these results, we conclude that the influence of capitalisation is indeed context dependent: Capitalisation aids processing most when no other cue is present. Thus, different cues play a role in NP recognition. Based on these findings, we argue that noun capitalisation should not be studied in isolation. We argue that a better understanding of capitalisation as a reading aid is relevant for teaching reading strategies.

AbstractUnderstanding the competition and coexistence of flagship carnivores is key to creating strategies for their conservation in the face of global carnivore declines. Although studies exploring the dynamics and competition between tigers (Panthera tigris) and leopards (P. pardus) span decades, there is a lack of understanding regarding the factors that influence their coexistence mechanisms on a broad scale, as well as the drivers determining their exploitative and interference competition. We gathered a comprehensive list of research papers among which 36 papers explored the interspecific interactions between tigers and leopards and tested the influence of biotic and abiotic factors on the coexistence mechanisms along three dimensions using multiple response variables regression models; we also tested the influence of ecological drivers determining the exploitative or interference competition between tigers and leopards. Elevation and ungulate density were the most important predictors in regulating the coexistence mechanisms. Tigers and leopards exhibited more positive relations/higher overlaps as elevation increased in the spatial niche. In addition, they showed a higher dietary overlap in the prey‐rich regions. We determined that interference competition between tigers and leopards was less frequently observed in habitats with dense tree cover and homogeneous vegetation structures. Meanwhile, studies with multiple metrics would promote the detection of interference competition. Our study provides new insight into the competitive interactions and coexistence mechanisms of tigers and leopards on a broad scale. Policy‐makers and managers should pay more attention to the factors of elevation, prey abundance, and habitat structures for the conservation of tigers and leopards.
Institutional investors' corporate site visits and resource extraction: Evidence from China

Published: May 2023

AbstractThis study examines the effect of corporate site visits on resource extraction. Taking advantage of China's mandatory disclosure of detailed investors' site visits information, we find that firms with more investors' site visits have lower levels of managerial private consumption and tunnelling. This association is more pronounced when the monitoring effect of corporate site visits is more efficient, and the agency problem is more severe. We utilise the two‐stage least squares (2SLS) estimation approach to demonstrate the robustness of our results. Collectively, our findings highlight the external monitoring role of investors' site visits in reducing corporate agency conflicts.

SummaryGlutamine metabolic reprogramming in acute myeloid leukaemia (AML) cells contributes to the decreased sensitivity to antileukemic drugs. Leukaemic cells, but not their myeloid counterparts, largely depend on glutamine. Glutamate dehydrogenase 1 (GDH1) is a regulation enzyme in glutaminolysis. However, its role in AML remains unknown. Here, we reported that GDH1 was highly expressed in AML: high GDH1 was one of the independent negative prognostic factors in AML cohort. The dependence of leukaemic cells on GDH1 was proved both in vitro and in vivo. High GDH1 promoted cell proliferation and reduced survival time of leukaemic mice. Targeting GDH1 eliminated the blast cells and delayed AML progression. Mechanistically, GDH1 knockdown inhibited glutamine uptake by downregulating SLC1A5. Moreover, GDH1 invalidation also inhibited SLC3A2 and abrogated the cystine‐glutamate antiporter system Xc−. The reduced cystine and glutamine disrupted the synthesis of glutathione (GSH) and led to the dysfunction of glutathione peroxidase‐4 (GPX4), which maintains the lipid peroxidation homeostasis by using GSH as a co‐factor. Collectively, triggering ferroptosis in AML cells in a GSH depletion manner, GDH1 inhibition was synthetically lethal with the chemotherapy drug cytarabine. Ferroptosis induced by inhibiting GDH1 provides an actionable therapeutic opportunity and a unique target for synthetic lethality to facilitate the elimination of malignant AML cells.
Inequalities by sex on remaining teeth in adults: A decomposition analysis

Published: May 2023

AbstractObjectiveTo identify which social determinants of health explain the gap in the remaining teeth between men and women.MethodsA secondary analysis of data from the Chilean National Health Survey (CNHS) 2016–2017 was performed on the number of remaining teeth in adults. The explanatory variables were organized into structural and intermediate social determinants of health according to the WHO framework. The contribution of both groups and the contribution of each individual explanatory variable to the remaining teeth gap was estimated using the Blinder‐Oaxaca decomposition analysis.ResultsThe predicted average number of remaining teeth for men was 23.4 and 21.0 for women, thus a mean difference of 2.4 teeth. 49.8% of the inequality between men and women was due to the different distribution (endowments) of the predictors in the model. Among them, structural determinants of health, namely education level (15.8%) and employment status (17.8%), contributed the most. Intermediate determinants had no relevant contribution to explain the gap.ConclusionsResults revealed that the difference in the mean number of remaining teeth between men and women was mainly explained by two structural determinants: education level and employment status. The lack of explanatory power of intermediate determinants and the large explanatory power of structural determinants means that tackling oral health inequity in Chile requires strong political commitment. The role of intersectoral and intersectional public policies to address gender inequalities in oral health in Chile is discussed.
MesoGAN: Generative Neural Reflectance Shells

Published: May 2023

AbstractWe introduce MesoGAN, a model for generative 3D neural textures. This new graphics primitive represents mesoscale appearance by combining the strengths of generative adversarial networks (StyleGAN) and volumetric neural field rendering. The primitive can be applied to surfaces as a neural reflectance shell; a thin volumetric layer above the surface with appearance parameters defined by a neural network. To construct the neural shell, we first generate a 2D feature texture using StyleGAN with carefully randomized Fourier features to support arbitrarily sized textures without repeating artefacts. We augment the 2D feature texture with a learned height feature, which aids the neural field renderer in producing volumetric parameters from the 2D texture. To facilitate filtering, and to enable end‐to‐end training within memory constraints of current hardware, we utilize a hierarchical texturing approach and train our model on multi‐scale synthetic datasets of 3D mesoscale structures. We propose one possible approach for conditioning MesoGAN on artistic parameters (e.g. fibre length, density of strands, lighting direction) and demonstrate and discuss integration into physically based renderers.

AbstractBackgroundNarrow diameter implants (NDIs) are used in cases of limited mesio‐distal space, or if the alveolar ridge does not allow placement of a standard diameter implant.PurposeThe aim of this prospective case series study is to present the 5‐year clinical‐, radiological‐, and patient‐reported outcome measures (PROMs) of patients with partial edentulism in the anterior area of the jaws requiring the placement of two narrow diameter implants to support a 3‐ or 4‐unit fixed partial denture (FPD).Materials and MethodsThirty partially edentulous patients missing 3 or 4 adjacent teeth in the anterior area of the jaws were included in the study. Two titanium–zirconium tissue‐level NDIs were placed in each patient in healed anterior sites (60 implants). A conventional loading protocol was performed to provide a FPD. Implant survival, success, marginal bone‐level changes (MBL), clinical parameters, buccal bone stability with CBCT, adverse events and PROMs were recorded.ResultsThe survival and success rates for the implants were 100%. The mean MBL (±SD) after prosthesis delivery, and 5‐year follow‐up (mean 58.8 months; range: 36–60) was 0.12 ± 0.22 and 0.52 ± 0.46 mm, respectively.Decementation and screw loosening were the most frequent prosthetic complications, yielding a prosthetic survival and success rates of 100% and 80%, respectively. Patient satisfaction was high with a mean (±SD) score of 89.6 ± 15.1.ConclusionsThe use of tissue‐level titanium–zirconium NDIs supporting splinted multi‐unit FPDs in the anterior area seems to be a safe and predictable treatment option after a 5‐year follow‐up period.
Practicing ecological citizenship through community supported agriculture: Opportunities, challenges, and social justice concerns
Authors: Misra Manoj 
Published: May 2023

AbstractGreen political theorists often highlight local food systems as an exemplar of ecological citizenship. Nevertheless, the topic has received scant systematic and critical treatment within green political theory. Although local food initiatives generally tend to be environmentally friendly, not all such initiatives lead to better environmental outcomes, nor can they be essentially characterized as citizenship practices that foster social justice. This article argues that a situated analysis is necessary to understand how a particular local food initiative promotes ecological citizenship. Through a qualitative study of community supported agriculture (CSA) participants in the greater Edmonton region of Canada, this article analyzes the civic virtues nurtured by this community and interrogates the extent to which their everyday practices resemble ecological citizenship. It concludes that discursive and structural limitations prevent the Edmonton CSA community from achieving meaningful diversity and addressing social justice concerns within its realm.
