Evaluation of Community Tourism Empowerment of Ancient Town Based on Analytic Hierarchy Process: A Case Study of Zhujiajiao, Shanghai

The research on community empowerment in the protection and utilization of ancient towns has practical significance for the sustainable development of ancient towns. Combined with empirical research, questionnaire survey, this paper analyzes the residents’ awareness of empowerment in the community participation of tourism, taking Zhujiajiao ancient town as a case study. Firstly, the evaluation system of community empowerment is established from four dimensions, including economy, society, politics, and psychology. Secondly, the weights of various factors are calculated by using the analytic hierarchy process, and the status quo of community tourism empowerment is comprehensively evaluated by the fuzzy analysis method. The results show that the degree of community empowerment in Zhujiajiao ancient town is between “average” and “good”. Psychological empowerment has the best score, while political empowerment is relatively weak. So, the dilemma of the top-down participation system needs to be changed. Self-government tourism organizations and the rules of income distribution should be established along with the ability training of tourism management to optimize the community participation mechanism. Application of the analytic hierarchy process to ancient town tourism empowerment is a new attempt and the evaluation scale can be used to other similar sites. Strategies in this paper have referential value for tourism sustainability in practice.
Neurally Adjusted Ventilatory Assistance and Synchronized Intermittend Mandatory Ventilation in Children Assessed by Electrical Impedance Segmentography: A Prospective Randomized Case-Control Crossover Trial

Background: Assessing relative differences of integrated impedance as a surrogate of volume changes between neurally adjusted ventilatory assist (NAVA) and synchronized intermittent mandatory ventilation (SIMV) by using electric impedance segmentography in children.Methods: Performed as a prospective randomized case-control crossover trial in a pediatric intensive care unit of a tertiary center including eight mechanically-ventilated children, four sequences of two different ventilation modes were consecutively applied. The children were randomized in two groups; one that was started on neurally adjusted ventilatory assist and the other on synchronized intermittent mandatory ventilation. During ventilation, electric impedance segmentography measurements were recorded.Results: The relative difference of vertical impedance between both ventilatory modes was measured (median 0.52, IQR 0-0.87). These differences in left apical lung segments were present during the first (median 0.58, IQR 0-0.89, p=0.04) and second crossover (median 0.50, IQR 0-0.88, p=0.05) as well as across total impedance (0.52 IQR 0-0.87; p=0.002). During neurally adjusted ventilatory assist children showed a shift of impedance towards caudal lung segments, compared to synchronized intermittent mandatory ventilation.Conclusion: Electrical impedance segmentography enables dynamic monitoring of transthoracic impedance. Segmental measurements, however, were of low reproducibility due to various limiting factors in its application. For further evaluation, larger prospective clinical trials are necessary.
Decomposition of Herbivore-Damaged Leaves of Understory Species Growing in Oak and Pine Stands

Leaves are the largest component of forest litter. Their decomposition rate depends mainly on plant species, leaf chemical composition, microorganism biodiversity, and habitat conditions. It is known that herbivory by insects can modify the chemical composition of leaves, such as through induction. The aim of this study was to determine whether the rate of leaf decomposition is related to the susceptibility of the plant species to insect feeding and how leaf damage affects this rate. For our research, we chose six species differing in leaf resistance to insect damage: Cornus sanguinea, Frangula alnus, and Sambucus nigra (herbivore resistant), and Corylus avellana, P. padus, and Prunus serotina (herbivore susceptible). The decomposition of these plant leaves was examined in two monoculture forest stands, deciduous (Quercus robur) and coniferous (Pinus sylvestris). Litter decay rate k and change of litter mass, content of defensive metabolites (total phenols (TPh) and condensed tannins), and substances beneficial for organisms decomposing litter (nitrogen (N) and nonstructural carbohydrates (TNC)) were determined. Contrary to our expectations, leaf litter of herbivore-resistant species decomposed faster than that of herbivore-susceptible species, and damaged leaves decayed faster than undamaged leaves. We found that faster decaying leaf litter had a lower content of defensive compounds and a higher content of TNC and N, regardless of the plant species or leaf damage. Leaf litter decomposition caused a large and rapid decrease in the content of defensive compounds and TNC, and an increase in N. In all species, the tannin content was lower in damaged than in undamaged leaves. This pattern was also observed for TPh, except in S. nigra. We interpret this as the main reason for faster decay of damaged leaves. Moreover, the loss of leaf mass was greater under oak than pine stands, indicating that the microorganisms in deciduous stands are more effective at decomposing litter, regardless of leaf damage.
RF Energy Harvesting Using High Impedance Asymmetric Antenna Array Without Impedance Matching Network

This manuscript presents a rectenna with a high impedance asymmetric antenna array for ambient wireless energy harvesting at the 2.45 GHz frequency band. It is fulfilled without using any impedance matching networks, which demonstrations significant benefits over available rectennas as a function of the layout and cost with a wide range of input power level and load impedance. A rectenna prototype has been designed, fabricated, and tested. The rectenna configuration is etched on a single layer, commercial, low‐cost FR4 substrate. Simulation and experiments have been carried out. The results show that the proposed rectenna features a good characteristic of RF to DC conversion efficiency. Over 60% (up to 67%) RF‐DC conversion efficiency is realized for the input power levels from 12 to 21 dBm and load impedance between 1,200 and 8,100 Ω. The proposed rectenna can be suitable for powering many low‐power electronic devices, because of simple structure and low cost.
First Isolation and Genetic Characterization of Bovine Herpesvirus 1 From Cattle in Pakistan

The study was aimed to isolate BoHV-1 circulating in Lahore, Pakistan and its genetic characterization. For this purpose, blood samples were collected from different areas of district Lahore through convenient sampling technique. Out of 100 blood samples, 69 (69%, 95% CI: 58.86-77.66) samples have shown seropositivity against BoHV-1 through ELISA. For the isolation of BoHV-1, nasal swab samples were collected from 69 seropositive cattle and buffalo. Out of 69 nasal swab samples, only 6 samples have shown the visible cytopathic effect and confirmed through nested polymerase chain reaction by targeting glycoprotein B (gB). The phylogenetic analysis showed that local isolates showed similarity to subtype 1.1 of BoHV-1 and had 99-100% homology with Cooper strain. It was concluded that BoHV-1.1 is being circulating in Pakistan and further studies are needed which will help for clear understanding of virus characterization and development of effective local vaccine
EFL Undergraduate Students’ Professional Identity Construction: A Sociocultural Perspective

Social relationship within a sociocultural context is considered to be one of the influencing factors involved in the process of teacher identity. The process is both complex and dynamic in which it demands individuals’ continual struggle and change due to the involvement of external and internal factors. This study investigated the process of professional identity construction of two EFL undergraduate students through their engagement in the educational environment and the teaching practicum context. The participants involved in this study were at the eighth academic semester of the Teacher-Education Study Program at University of Papua (UNIPA), Manokwari, Papua Barat and they had accomplished their teaching practicum in high schools in Manokwari. The student-teachers built their social interactions at with their peers and teacher-educators within their educational environment at the university and with their mentor-teachers, students and supervisors in their teaching practicum. A qualitative research was employed through semi-structured interview. The findings revealed that the process of students’ professional identity construction is both dynamic and unstable and shaped by the three intertwined factors in the identity construction process namely: self-perception, educational environment, and teaching practicum. The students’ self-perception changed through the process as an impact of their interactions with educational environment and teaching practicum. The significance of the contentment and impediments as the dimensions of these experiences shaped the students’ professional identities.
Carbon Stocks in Miombo Woodlands: Evidence From Over 50 Years

Miombo woodlands are extensive dry forest ecosystems in central and southern Africa covering ≈2.7 million km2. Despite their vast expanse and global importance for carbon storage, the long-term carbon stocks and dynamics have been poorly researched. The objective of this paper is to present and summarize the evidence gathered on above- and belowground (root and soil) carbon stocks of miombo woodlands from the 1960s to mid-2018 through a review. We analyzed data to answer: (1) What is the range of aboveground and belowground carbon stocks found in miombo woodlands over the last six decades? (2) Are there differences in carbon stocks based on land-management categories? (3) Does precipitation influence aboveground carbon stocks in old-growth miombo? (4) Do differences in cover type, age and region influence carbon stocks? (5) How does previous land-use affect carbon stocks in re-growth miombo? A literature review protocol was used to identify 56 publications from which quantitative data on aboveground and soil carbon pools were extracted. We found that the mean aboveground carbon stock in old-growth miombo was 30.83±16.76 Mg C ha-1 (range 1.48—107.24 Mg ha-1). Old-growth miombo had an average calculated root carbon stock of 16.49±9.18 Mg C ha-1 (range 0.8—57.81 Mg ha-1). Soil carbon stocks in old-growth miombo varied widely, between 8.75 and 134.6 Mg C ha-1 while in re-growth miombo they varied between 10.73 and 52.2 Mg C ha-1. It must be noted these soil data are given only for information; they inconsistently refer to varying soil depths and are thus difficult to interpret. The wide range reported suggests a need for further studies, much more systematic in methods and reporting. Other limitations of the dataset include the lack of systematic sampling and lack of data in some countries, viz. Angola and Democratic Republic of the Congo.
Wild, stressful, or stupid: Que es Bandersnatch? Exploring user outcomes of Netflix’s interactive Black Mirror episode

Prior scholarship related to interactive digital narratives (IDNs) typically has analyzed this emerging genre of storytelling on web-based platforms. The Bandersnatch episode of the Black Mirror series on Netflix offers a unique opportunity to explore the affordances and audience effects of IDNs appearing within a popular streamed TV program. This case study combines updated models of the uses and gratifications theory of media use with human–computer interaction frameworks to identify cognitive themes and emotional valences among Bandersnatch users, as expressed through tweets related to their experience. Findings show positive emotions were associated with perceived degree of control, as well as immersion or sense of flow. Gratifications associated with binge-type behavior on streaming services were also present. However, perceived realism, parasocial identification with the character, a need for a sense of completion, and the burden of choice created stress among many users. Social media served as a valuable ancillary vehicle for users to participate with others around the program, thus elevating the interactive narrative elements of the experience, which were otherwise limited and controlled.
The Role of Acoustic Similarity and Non-Native Categorisation in Predicting Non-Native Discrimination: Brazilian Portuguese Vowels by English vs. Spanish Listeners

This study tests whether Australian English (AusE) and European Spanish (ES) listeners differ in their categorisation and discrimination of Brazilian Portuguese (BP) vowels. In particular, we investigate two theoretically relevant measures of vowel category overlap (acoustic vs. perceptual categorisation) as predictors of non-native discrimination difficulty. We also investigate whether the individual listener’s own native vowel productions predict non-native vowel perception better than group averages. The results showed comparable performance for AusE and ES participants in their perception of the BP vowels. In particular, discrimination patterns were largely dependent on contrast-specific learning scenarios, which were similar across AusE and ES. We also found that acoustic similarity between individuals’ own native productions and the BP stimuli were largely consistent with the participants’ patterns of non-native categorisation. Furthermore, the results indicated that both acoustic and perceptual overlap successfully predict discrimination performance. However, accuracy in discrimination was better explained by perceptual similarity for ES listeners and by acoustic similarity for AusE listeners. Interestingly, we also found that for ES listeners, the group averages explained discrimination accuracy better than predictions based on individual production data, but that the AusE group showed no difference.
Altruism or social motives? evidence from online charitable giving in China

ABSTRACT Despite the rapid development of online charitable giving (OCG), there are few empirical studies on the motivations of OCG. This study examines two typical types of motivations (i.e., altruism and social motives). We build a model by combining the elaboration likelihood model (ELM) of persuasion with social influence theory. Using a dataset of 13,119 projects from Weibo Charity, a leading OCG platform in China, we find that the primary motivation of OCG comes from social motives rather than altruism. This study contributes to the relevant literature and provides practical implications for OCG project sponsors and platform managers.
Ggrafted antimicrobial cotton fabrics with N-halamine groups via atom transfer radical polymerization

An N-halamine precursor 2-(3-(6-methyl-4-oxo-1,4-dihydropyrimidin-2-yl)ureido)ethyl methacrylate (SCMHBMA) was synthesized and grafted on cotton fabrics via atom transfer radical polymerization for antibacterial function after chlorination. The preparation and chlorinated cotton fabrics (Cotton-g-PSMA-Cl) were characterized with FTIR, XPS, SEM, and TGA. The properties of prepared Cotton-g-PSMA-Cl, including thermal property, antibacterial efficiency, durability, and stability, were systematically evaluated. The results showed that these chlorinated Cotton-g-PSMA-Cl fabrics possessed excellent antibacterial activity against E. coli. and S. aureus. After 10 washing cycles and 60 days of routine storage, active chlorine concentrations (Cl+%) were reduced only 22% and 18%, respectively, and the reduced Cl+% effectively reverted by simple rechlorination. This new N-halamine antibacterial cotton composite with superior antibacterial properties exhibited potential for future application in the long-term antibacterial field.
Identification of Factors Influencing Development of Photovoltaic (PV) Implementation in Singapore

Despite the steady growth of grid-connected installed capacity in Singapore in the last decade and intensive government effort towards “solarization”, implementation of photovoltaics (PV) and especially building-integrated photovoltaics (BIPV) into the built environment has not gathered as much momentum as would have been expected given the country’s ample solar energy resource potential, strong economic fundamentals and the robust real estate sector. Based on a conducted web-survey and qualitative interviews among local professionals, this paper examines the obstacles, potentials and drivers that could facilitate and accelerate BIPV and PV façade integration, as well as needs that could encourage wider PV use. In order to define a unified strategy, aligning the stakeholders’ views, the following disputable factors are pointed out and discussed: (1) incomplete understanding of BIPV and building-applied photovoltaics (BAPV) among stakeholders, (2) costs of BIPV systems, (3) low awareness of and confidence in “integrability” of PV modules, (4) incomplete knowledge about and insufficiently investigated PV performance and (5) potential of PV façade and roof integration. Since the costs are the key identified factor for BIPV implementation, life-cycle cost (LCC) assessments of PV façade and roof integrations have been performed, which supported the search for solutions to identified problems. The performed analysis and findings present the basis for the development of a long-term holistic strategy for PV implementation in Singapore that could help the highly-urbanized, tropical resource- and land-constrained island city-state reduce the dependency on fossil fuels and achieve the climate change targets, thus promoting a more sustainable built environment.
Effect of fiber length and dispersion on properties of long glass fiber reinforced thermoplastic composites based on poly(butylene terephthalate)

Long glass fiber reinforced poly(butylene terephthalate) (LGF/PBT) composites with different original glass fiber lengths were prepared using a impregnation device designed by the authors. The influence of fiber length and fiber distribution on the properties of the LGF/PBT composites were studied. The results showed that the length of the residual glass fibers increased with the original glass fiber length increase of LGF/PBT composites. Scanning electron microscopy results indicated that the glass fibers of LGF/PBT composites (16 nm and 20 mm) were unevenly dispersed and this is a phenomenon of their reunion in the resin matrix. Various rheological plots including viscosity curve, storage modulus, loss modulus, and loss angle, were used to characterization the rheological properties of the pristine matrix and the LGF/PBT composites. Dynamic mechanical thermal analysis results indicated that the storage and loss modulus of the LGF/PBT composites firstly increase and then decrease with original glass fiber length. The storage and loss modulus, glass transition temperatures of the pristine matrix and LGF/PBT composites increase with test frequencies increase. The activation energies of glass transition relaxation for the activation energies for loss tangent (tan δ) and loss modulus (E′′) peaks were calculated. Furthermore, the glass transition relaxation determined from the tan δ peaks were more reliable than using the E′′ criterion. Differential scanning calorimetry analysis indicated that the crystallization temperature (Tc), percentage crystallinity (Xc) and melting point of the LGF/PBT composites firstly increased and then slightly decreased with the increase of the original glass fiber length. Thermogravimetry (TG) and differential thermal gravimetric analysis curves of the LGF/thermoplastic polyurethane (TPU)/PBT/polyethylene-butylacrylate-glycidyl methacrylate (PTW) composites were shifted to higher temperatures with the increase of the LGF content. Thermogravimetric analysis results showed that the TG curves of the LGF/TPU/PBT/PTW composites firstly shifted to higher temperatures and then shifted to lower temperatures as the original glass fiber length increased. The limiting oxygen values of the pristine matrix and LGF/PBT composites showed little change, which indicated that the effect of the original glass fiber length on the combustion behavior of LGF/PBT composites was not obvious. The tensile strength, notched Izod impact strength, flexural strength and modulus of the LGF/PBT composites firstly increase and then decrease with the original glass fiber length. When the original glass fiber length was 12 mm, the mechanical properties of LGF/PBT composites were optimal.
Effects of planted tree species on biodiversity of conifer plantations in Japan: a systematic review and meta-analysis

ABSTRACT Natural forests were increasingly replaced by plantations globally. While plantations support less biodiversity compared to natural forests, they can serve as an important habitat for forest-dependent species. Understanding the key drivers of the habitat function of plantations is necessary to reconcile both forestry and biodiversity. Planted tree species is one of the important factors determining biodiversity of plantations. Here, we systematically collected studies comparing the biodiversity between conifer plantations and natural forests, and conducted meta-analyses to quantify the effects of planted tree family/species (cypress family: Japanese cedar Cryptomeria japonica, Hinoki cypress Chamaecyparis obtuse; pine family: Japanese larch Larix kaempferi, Japanese red pine Pinus densiflora, Todo fir Abies sachalinensis) on abundance and species richness of a wide range of taxa (all taxa, vertebrates, birds, invertebrates, terrestrial arthropods, plants, and understorey plants) in plantations in Japan. Abundance and species richness in plantations relative to natural forests differed among planted tree family/species. In plantations of pine family (mainly larch), abundance or richness did not significantly differ from those in natural forests for many taxa, suggesting the important role as habitats. By contrast, in cypress family (mainly cedar), abundance or richness was significantly lower than in natural forests for all analysis groups except understorey abundance. These results indicate that the habitat function of plantations and its management should be considered for each planted tree species, separately. Nevertheless, since our literature review identifies some research gaps, e.g. studies on vertebrates in western Japan were scarce, more comprehensive research efforts should be made in the future.
