Published: November 2021

PurposeThe purpose of this paper is to understand the factors influencing content generation and community initiative in PESCs. Taking advantage of an emerging PESC – Xiaohongshu APP, the study identifies three antecedent resources, including customer-owned knowledge, harmonious passion to shopping and perceived information usefulness, that affect content generating and further community initiative.Design/methodology/approachBased on the service-dominant (S-D) logic model and resource integration related work, the authors proposed a conceptual framework empirically tested using data of a survey and the real content-generating behavior from 347 respondents.FindingsThis paper identifies three resource antecedents of content generating behavior with significant influence. Furthermore, there is a moderating effect of perceived information usefulness among these three resources, which echoes the concept of resource integration. Content generating has a significant and positive influence on community initiative.Originality/valueFirst, the paper identified customer and platform resources promoting the prosperity of PESCs, enhancing the research on antecedents of community prosperity. Second, the paper empirically quantifies the process and outcome of resource integration conceptual model. Third, it enriches the understanding of C2C interaction by investigating the value creation process on PESCs. Moreover, findings in the study provide insights for community managers to improve the operation of PESCs.

Abstract

At the start of the UN Decade of Ecosystem Restoration (2021–2030), the restoration of degraded ecosystems is more than ever a global priority. Tree planting will make up a large share of the ambitious restoration commitments made by countries around the world, but careful planning is needed to select species and seed sources that are suitably adapted to present and future restoration site conditions and that meet the restoration objectives.

Here we present a scalable and freely available online tool, Diversity for Restoration (D4R), to identify suitable tree species and seed sources for climate‐resilient tropical forest landscape restoration.

The D4R tool integrates (a) species habitat suitability maps under current and future climatic conditions; (b) analysis of functional trait data, local ecological knowledge and other species characteristics to score how well species match the restoration site conditions and restoration objectives; (c) optimization of species combinations and abundances considering functional trait diversity or phylogenetic diversity, to foster complementarity between species and to ensure ecosystem multifunctionality and stability; and (d) development of seed zone maps to guide sourcing of planting material adapted to present and predicted future environmental conditions. We outline the various elements behind the tool and discuss how it fits within the broader restoration planning process, including a review of other existing tools.

Synthesis and applications. The Diversity for Restoration tool enables non‐expert users to combine species traits, environmental data and climate change models to select tree species and seed sources that best match restoration site conditions and restoration objectives. Originally developed for the tropical dry forests of Colombia, the tool has now been expanded to the tropical dry forests of northwestern Peru–southern Ecuador and the countries of Burkina Faso and Cameroon, and further expansion is underway. Acknowledging that restoration has a wide range of meanings and goals, our tool is intended to support decision making of anyone interested in tree planting and seed sourcing in tropical forest landscapes, regardless of the purpose or restoration approach.

Abstract

The prediction that higher biodiversity leads to denser niche packing and thus higher community resistance to invasion has long been studied, with species richness as the predominant measure of diversity. However, few studies have explored how phylogenetic and functional diversity, which should represent niche space more faithfully than taxonomic diversity, influence community invasibility, especially across longer time frames and over larger spatial extents.

We used a 15‐year, 150‐site grassland dataset to assess relationships between invasive plant abundance and phylogenetic, functional and taxonomic diversity of recipient native plant communities. We analysed the dataset both pooled across all surveys and longitudinally, leveraging time‐series data to compare observed patterns in invasion with those predicted by two community assembly processes: biotic resistance and competitive exclusion. We expected more phylogenetically and functionally diverse communities to exhibit greater resistance to invasion.

With the pooled dataset, we found support for the long‐standing observation that communities with more native species have lower abundance of invasive species, and a more novel finding that more phylogenetically diverse communities had higher abundance of invasive species. We found no influence of aggregate (multivariate) functional diversity on invasion, but assemblages with taller plants, lower variability in plant height and lower seed mass were less invaded. Viewed longitudinally, the phylogenetic diversity relationship was reversed: the most phylogenetically diverse communities were most resistant to invasion. This apparent discrepancy suggests invasion dynamics are influenced by both site attributes and biotic resistance and emphasizes the value in studying invasion across time.

Synthesis. Our results provide insight into the nuances of the diversity–invasibility relationship: invasion dynamics differed for different dimensions of diversity and depending on whether the relationship was evaluated longitudinally. Our findings highlight the limitations of using single time‐point ‘snapshots’ of community composition to infer invasion mechanisms.
Differences in trends of perceived inpatient care quality based on regional socioeconomic level in the United States and Taiwan
Authors: Yoon Grace H. , Cheng Shou‐Hsia 
Published: November 2021

AbstractObjectiveTo examine perceived inpatient care quality according to regional socioeconomic status (SES), measured by regional household income, across the United States and Taiwan.Data sourcesPatient Experience in Hospital Care (PEHC) survey 2018–2019 data from National Taiwan University; US Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) 2018–2019 data from CMS.gov; and household income and facility data from publicly accessible databases.Study designThis retrospective study used multivariate logistic regression to estimate the effect of household income on the rate of positive inpatient experiences in Taiwan and the United States, adjusting for hospitals' teaching status and ownership, and physician density.Data collectionHospital administrators for HCAHPS and PEHC's research teams invited patients who received inpatient care during the data collection period in the United States and Taiwan, respectively. The analysis included 1024 facilities from nine US states and 350 facilities from twenty major cities/counties in Taiwan.Principal findingsPerceived inpatient care quality was higher in the United States than in Taiwan for the three experience measures. In Taiwan, hospitals with higher regional SES were less likely to receive a highly positive response for perceived respect, accommodation quality, and understanding upon discharge, with odds ratios (ORs) ranging from 0.83 to 0.88. In contrast, in the United States, higher regional SES was associated with a higher likelihood of a positive response for accommodation quality and understanding upon discharge (ORs = 2.51 and 1.48). Regional physician density and individual hospital characteristics show varying effects on perceived quality between Taiwan and the United States.ConclusionsHigher overall experience scores in the United States are consistent with higher spending on health care compared with Taiwan. Varying associations between regional SES and perceived inpatient care quality highlight how systemic and cultural differences between the two countries affect scoring patterns.
Modelling changing patterns in the COVID‐19 geographical distribution: Madrid’s case
Authors: Maza Adolfo , Hierro María 
Published: November 2021

AbstractWe analyse the transmission factors shaping the spatial distribution of COVID‐19 infections during the distinct phases of the pandemic’s first wave in Madrid, Spain, by fitting a spatial regression model capturing neighbourhood effects between municipalities. Our findings highlight that factors such as population, mobility, and tourism were instrumental in the days before the national lockdown. As a result, already in the early part of the lockdown phase, a geographical pattern emerged in the spread of the disease, along with the positive (negative) impact of age (wealth) on virus transmission. Thereafter, spatial links between municipalities weakened, as the influences of mobility and tourism were eroded by mass quarantine. However, in the de‐escalation phase, mobility reappeared, reinforcing the geographical pattern, an issue that policymakers must pay heed to. Indeed, a counterfactual analysis shows that the number of infections without the lockdown would have been around 170% higher.
Students as digital multimodal text designers: A study of resources, affordances, and experiences
Authors: Dahlström Helene 
Published: November 2021

AbstractThis paper addresses how students design multimodal digital text when making digital stories in school. Drawing on the perspective of ‘multiliteracies’, multimodal analysis of video recordings was used to understand the data. Findings revealed that (a) multimodal digital text making requires particular digital and modal text‐making skills and knowledge, such as knowledge of photography, film, film editing, image searching, and audio recording; (b) students' prior knowledge was crucial for mastering the digital and modal affordances offered when making digital stories; and (c) making multimodal digital texts in school offers increased opportunities for students to perform and succeed in text making. These findings point to the need for schools to offer education that makes it possible for all students to gain knowledge and master skills needed for contemporary text making. Such knowledge goes beyond skills and practices needed when making paper‐based text, and borders on other disciplines such as art and technology.
Practitioner notesWhat is already known about this topic

Text making in the 21st century entails working in various modes, such as images, writing, and video, and is often performed with digital resources.
Today's students must be competent in designing multimodal texts that are commonly associated with digital technology and multimedia.
Students' modal choices when creating digital texts are influenced by prior experiences and knowledge of text‐making practices obtained outside school.
What this paper adds

This paper provides examples of the differing prerequisites of students designing a digital multimodal story.
This paper offers insights into the particular digital and modal text‐making skills and knowledge necessary for students to become competent text makers.
Multimodal digital texts activities in school offers increased opportunities for students to perform and succeed in text making.
Implications for practice and/or policy

The results of this study have implications for literacy practices as well what is included in the literacy curriculum. This study provides implications for education that intends to reduce inequalities in students' prerequisites concerning making digital multimodal texts, and examines the text‐making experiences, knowledge, and skills students already possess upon entering the classroom.
Classroom‐based instruction and opportunities for digital creation can bridge the gap between student's informal text‐making activities and formal text‐making activities at school and help to close the digital divide among students.

AbstractAlzheimer's disease (AD) causes cognitive impairment in the elderly and is a severe problem worldwide. One of the major reasons for the pathogenesis of AD is thought to be due to the accumulation of amyloid beta (Aβ) peptides that result in neuronal cell death in the brain. In this study, bioassay‐guided fractionation was performed to develop seed compounds for anti‐AD drugs that can act as dual inhibitors of BACE1 and Aβ aggregation from secondary metabolites produced by Streptomyces sp. To improve the solubility, the crude extracts were methylated with trimethylsilyl (TMS) diazomethane and then purified to yield polyketides 1–5, including the new compound 1. We synthesized the compounds 6 and 7 (original compounds 2 and 3, respectively), and their activities were evaluated. KS‐619‐1, the demethylated form of 4 and 5, was isolated and evaluated for its inhibitory activity. The IC50 values for BACE1 and Aβ aggregation were found to be 0.48 and 1.1 μM, respectively, indicating that KS‐619‐1 could be a lead compound for the development of therapeutic agents for AD.
‘With every fibre of their being’: Perspectives of healthcare professionals caring for children with non‐malignant life‐limiting conditions
Authors: Kiernan Gemma , Hurley Fiona , Price Jayne 
Published: November 2021

AbstractBackgroundChildren with non‐malignant life‐limiting conditions (NMLLCs) constitute the largest proportion of children requiring palliative care. In part, due to technological advances, growing numbers of such children are experiencing improved survival. Care is mostly provided at home by the family, with significant professional input at different points in the child's life trajectory. This study explored the experience of healthcare professionals caring for this cohort of children.MethodsA qualitative descriptive study design using single‐occasion one‐to‐one semi‐structured interviews collected data from 12 healthcare professionals' including nurses, social workers and doctors. Data were analysed using thematic analysis.ResultsThe findings highlighted the unfailing determination and dedication of healthcare professionals who provided care despite challenges with what seemed like ‘with every fibre of their being’. Three key themes marked such strength and commitment; those were ‘being there’, ‘being focused’ and ‘being strong’. ‘Being there’ explicitly highlighted expert care that was individualized and responsive to the child and family's unique needs. The provision of such care was often threatened and potentially compromised by the intricacies and challenges associated with children's palliative care (CPC) and service provision. ‘Being focused’ captured the sense that the healthcare professionals remained entirely focused on providing expert care despite these challenges. ‘Being strong’ epitomized the personal and professional impact on healthcare professionals who are working in this area and the manner in which they sustain themselves in ‘being focused’ and in ‘being there’.ConclusionsThe healthcare professionals demonstrated their unwavering commitment to deliver quality care required by children and families, however against a background of issues relating to organizational constraints. The findings have implications for education/service providers such as the need for specific palliative care education at both pre‐registration level and continuing professional development.

Published: November 2021

AbstractIntroductionParkinson's (PD) is a common degenerative disease of the central nervous system. It affects more than 6 million individuals worldwide. The typical clinical manifestations include static tremor, slow movement, and unstable posture. However, the correlation between head tremor and the severity of PD remains unclear.MethodsIn the current study, 18 patients and 18 healthy subjects were recruited to undergo a phonation test. Noldus facereader 7.0 software was used to analyze the range of head trembling between the two groups.ResultsThe data revealed that patients with PD had significant differences in the x‐, y‐, and z‐axis of head movement with respect to the specific pronunciation syllables compared with the normal group. Moreover, the head movement of the patients with PD was positively correlated with the severity of the disease in the single, double, and multiple syllable tests. In the phonetic test, the head displacement of patients with PD was significantly greater than that of healthy individuals, and the displacement range was positively correlated with the severity of the disease.ConclusionThese pieces of evidence suggested that the measurement of head displacement assists the early diagnosis and severity of the disease.

AbstractIterated language learning experiments that explore the emergence of linguistic structure in the laboratory vary considerably in methodological implementation, limiting the generalizability of findings. Most studies also restrict themselves to exploring the emergence of combinatorial and compositional structure in isolation. Here, we use a novel signal space comprising binary auditory and visual sequences and manipulate the amount of learning and temporal stability of these signals. Participants had to learn signals for meanings differing in size, shape, and brightness; their productions in the test phase were transmitted to the next participant. Across transmission chains of 10 generations each, Experiment 1 varied how much learning of auditory signals took place, and Experiment 2 varied temporal stability of visual signals. We found that combinatorial structure emerged only for auditory signals, and iconicity emerged when the amount of learning was reduced, as an opportunity for rote‐memorization hampers the exploration of the iconic affordances of the signal space. In addition, compositionality followed an inverted u‐shaped trajectory raising across several generations before declining again toward the end of the transmission chains. This suggests that detection of systematic form‐meaning linkages requires stable combinatorial units that can guide learners toward the structural properties of signals, but these combinatorial units had not yet emerged in these unfamiliar systems. Our findings underscore the importance of systematically manipulating training conditions and signal characteristics in iterated language learning experiments to study the interactions between the emergence of iconicity, combinatorial and compositional structure in novel signaling systems.

AbstractWe aimed at examining the impact of wearing surgical face masks on exercise performance. Thirty‐two healthy adults (16 males and 16 females) completed a graded exercise test to measure peak oxygen uptake (VO2peak) and the ventilatory threshold (VT). Then, on separate days, all participants performed resting and standardized protocols (moderate intensity: 25% infra‐VT; severe intensity: 25% supra‐VT) on two different conditions (with and without a surgical mask). The use of masks reduced both VO2 and minute ventilation during moderate and severe exercise (p < 0.0001), and this effect was particularly pronounced during severe exercise. Time to exhaustion was also shortened by ~10% on the face mask condition (p = 0.014). In contrast, neither heart rate nor the respiratory exchange ratio was affected by masking. The submaximal VO2 was similar between the two epochs of analysis obtained during moderate cycling (i.e. 3–6 min vs. 7–10 min) and this occurred similarly between conditions. In conclusion, the impact of the surgical masks on exercise capacity is particularly pronounced during severe exercise performed at constant work rate. Ultimately, this may implicate a considerable impairment of structured or even unstructured strenuous physical activity. Clinical Trials registration number: NCT04963049.
