Metro station inauguration, housing prices, and transportation accessibility: Tehran case study

The opening of a new metro station, as a mode of the transportation corridor, potentially could have different effects on housing prices. We have investigated its effect on the value of residential properties around those stations, using data from large expansions of the metro network in Tehran, Iran. In the period of our study (April 2010 to December 2018), forty-five metro stations were inaugurated in Tehran. We use a difference-in-difference regression method to identify the causal effect of interest, where adjacent properties are used as the treatment group and similar but distant properties as the control group. The results indicate that, on average, the adjacent properties are affected by a 3.7 percent increase in price relative to distant properties. We also extend our study by categorizing new metro stations according to the extent of ex-ante access to other modes of public transportation such as bus rapid transit (BRT). We find 2 to 11 percent positive effect of new metro stations in regions with lower public transport, while in regions with ex-ante extensive public transportation system, we find less than 2 percent positive effect.
High‐Performance Flexible Solid‐State Ni/Fe Battery Consisting of Metal Oxides Coated Carbon Cloth/Carbon Nanofiber Electrodes

Aqueous Ni/Fe batteries have great potential as flexible energy storage devices, owing to their low cost, low toxicity, high safety, and high energy density. However, the poor cycling stability has limited the widely expected application of Ni/Fe batteries, while the use of heavy metal substrates cannot meet the basic requirement for flexible devices. In this work, a flexible type of solid‐state Ni/Fe batteries with high energy and power densities is rationally developed using needle‐like Fe3O4 and flake‐like NiO directly grown on carbon cloth/carbon nanofiber (CC–CF) matrix as the anode and cathode, respectively. The hierarchical CC–CF substrate with high electric conductivity and good flexibility serves as an ideal support for guest active materials of nanocrystalline Fe3O4 and NiO, which can effectively buffer the volume change giving rise to good cycling ability. By utilizing a gel electrolyte, a robust and mechanically flexible quasi‐solid‐state Ni/Fe full cell can be assembled. It demonstrates optimal electrochemical performance, such as high energy density (5.2 mWh cm−3 and 94.5 Wh Kg−1), high power density (0.64 W cm−3 and 11.8 KW Kg−1), together with excellent cycling ability. This work provides an example of solid‐state alkaline battery with high electrochemical performance and mechanical flexibility, holding great potential for future flexible electronic devices.
Microbiological quality of ready-to-eat meat and meat products sold in Mumbai city

Microbial quality of ready-to-eat (RTE) chicken burger, chicken pizza, chicken lollypop, chicken pattice, chicken roll, mutton chop, mutton burger, mutton kabab and mutton samosa sold in Mumbai on railway stalls, small shops and streets were assessed. All the RTE foods had high total viable count (log cfu/g 7.21±1.55), Staphylococcal count (log cfu/g 3.88±2.10), Fecal coliform count (log cfu/g 4.70±2.37) and Fecal Streptococcal count (log cfu/g 3.56+2.25). Coagulase positive S. aureus was isolated from 7.7% samples of chicken roll and mutton chop, 7.1% of mutton burger and 6.6% of chicken pizza. S. enteritidis was detected in one sample each of chicken roll and mutton chop; S. gallinarum in chicken pizza, chicken burger and chicken pattice and S. typhimurium in mutton burger. Packed samples of chicken pizza are potential source of all the organisms. Type of outlet did not have any significant effect on the quality of chicken and mutton based RTE food. Street samples are more hazardous followed by small shop and railway stall samples.
High Temperature Thermoelectric Properties of Yb 14 MnSb 11 Prepared from Reaction of MnSb with the Elements

Compounds of the Yb14MnSb11 structure type are the highest efficiency bulk p-type materials for high temperature thermoelectric applications, with reported figures of merit (ZTs) as high as ∼1.3 at 1275 K. Further optimization of ZT for this structure type is possible with the development of a simple synthetic route. However, this has been difficult to achieve because of the small amount of Mn required compared with Yb and Sb. A simple synthetic route for Yb14MnSb11 has been developed utilizing a combination of ball milling and annealing to produce phase-pure material followed by spark plasma sintering for consolidation. The materials have been characterized by powder X-ray diffraction before and after spark plasma sintering. The stoichiometric reaction of Yb, Sb, and MnSb provides phase-pure powder by X-ray diffraction. Upon cycling to temperatures greater than 1272 K, Yb14MnSb11 shows the presence of Yb11Sb10. Additional samples with 5% and 10% excess Mn were also investigated. Adding 5–10% excess Mn do.
Conceptual Model of Integrated Agrotourism Marketing

Agrotourism becomes an increasingly popular concept of tourism. Research on agrotourism generally separately and unrelated. Most agrotourism research is conducted from the supply side and only a few from the demand side. This paper proposes agrotourism marketing by integrating the parties involved in agrotourism (tourists, government, farmers, accommodation companies, and travel companies). This study proposes to conceptualize tourist intentions with interrelated and complementary agrotourism development policies and strategies to effective agrotourism marketing. This paper is useful for the parties involved in agrotourism to increase the effectiveness of agrotourism marketing and for the development of agrotourism. From the demand side, this study uses motivation theory and extended TPB in the context of agrotourism. From the supply side using expert opinion from the government, farmers, accommodation companies, and transportation companies This research is expected to contribute to consumer behavior research.
Uric Acid Abnormalities and Its Correlation with Splenectomy in Adult Transfusion Dependent Thalassemia Subjects (TDT)

Background: In thalassemia patients erythrocyte turnover rate increases due to chronic hemolysis and ineffective erythropoiesis leading to increase in uric acid production. Hyperuricosuria is one of the marker of proximal tubular dysfunction. Splenectomy can increase the risk of hyperuricemia by increasing erythrocyte turnover rate in Transfusion Dependent Thalassemia (TDT). Deferasirox enhances uric acid excretion from renal tubules leading to low serum uric acid levels. Methods: An institution based cross-sectional study was conducted from November 2018-March 2020 which included 60 adult TDT patients (≥18 years) attending Adult Thalassemia Day Care Centre at tertiary care hospital. Serum uric acid (mg/dl), 24 hour urinary uric acid (mg/dl), serum ferritin (ng/ml) were done. Results: Hyperuricemia was present in 20%, hypouricemia in 3.33%. Hyperuricosuria was present in 80%. Mean SUA levels were higher in males than females which was statistically significant (5.77±1.66 vs 4.64±1.44, p=0.007). There was statistically significant positive correlation between serum uric acid and serum creatinine(p = 0.0036) and age (p=0.0129). Hyperuricemia was more in subjects with intact spleen but was not statistically significant(p=0.104). Hyperuricemia had negative association with deferasirox therapy [1 (3.03%) vs 11 (40.74%), p=0.0004] compared with normouricemia subjects. Conclusion: Uric acid abnormalities were seen in 23.3% of patients. Hyperuricemia was present in one fourth of the patients and significant risk factors were increasing age, male gender, rising serum creatinine. Deferasirox therapy was negatively associated with hyperuricemia. Tubular dysfunction is relatively common in TDT as more than three fourth patients had hyperuricosuria. Regular monitoring of serum uric acid and urinary uric acid is recommended.
Air Control Toolbox (ACT_v1.0): a machine learning flexible surrogate model to explore mitigation scenarios in air quality forecasts

Abstract. We introduce the first toolbox that allows exploring the benefit of air pollution mitigation scenarios in the every-day air quality forecasts through a web interface. Chemistry-transport models (CTMs) are required to forecast air pollution episodes and assess the benefit that shall be expected from mitigation strategies. However, their complexity prohibits offering a high level of flexibility. The Air Control Toolbox relies on machine learning methods to cope with this limitation. It consists of a surrogate model trained on a limited set of sensitivity scenarios to allow exploring any combination of mitigation measures. As such we take the best of the physical and chemical complexity of CTMs, operated on high performance computers for the everyday forecast, but we approximate a simplified response function that can be operated through a website to emulate the main sensitivities of the atmospheric system for a given day and location. The numerical experimental plan to design the structure of the surrogate model is detailed by increasing level of complexity. The selected structure of the surrogate is a quadrivariate polynomial of first order for residential heating emissions, and second order for agriculture, industry and traffic emissions with three interaction terms. It is fitted to 12 sensitivity CTM simulations, at each grid point and every day for PM10, PM2.5, O3 (both as daily mean and daily maximum) and NO2. The validation study demonstrates that we can keep relative errors below 2 % at 95 % of the grid points and days for all pollutants. Various applications of the toolbox are presented for air quality episode analysis, source apportionment, and chemical regime analysis.
Chemical speciation of some heavy metals and human health risk assessment in soil around two municipal dumpsites in Sagamu, Ogun state, Nigeria

Abstract Environmental and health risk posed by heavy metals from municipal landfill cannot be over emphasized. However, the toxicity and fate of metal in the soil is dependent on its chemical form and therefore quantification of the different forms of metal is more meaningful than the estimation of its total concentration. This study investigated the chemical form and potential hazards of heavy metal pollution at two municipal landfills in Sagamu, Ogun state, Nigeria. Soil samples were collected around the landfills and chemical form of Cu, Zn, Cd, Pb, and Fe were studied, using the Tessier Five-step sequential chemical extraction procedure. The results showed that Cu and Fe were speciated into residual fractions with averages of 23.9 and 31.3% respectively, while Cd and Zn were associated with Carbonate fractions with respective averages of 20.3 and 20.6%. The order of mobility and bioavailability of these metals are: Cd > Pb > Cu > Zn > Fe. A comparison of the result of total extractible metals with standard set by USEPA reveals that Cd and Cu level in the dumpsite soils are far above the critical permissible limit of 3.0 and 250 mg kg−1, respectively which potent a health risk. Assessment of soil pollution level using geoaccumulation index (Igeo) revealed that the landfill was extremely polluted by Cd (Igeo > 5). Pearson correlation and principal component analysis showed that there were no significant correlations (p < 0.05) among all the metals, suggesting that they are all from different anthropogenic sources. The cancer risk ranged from 1.36E−01 to 2.18E−04 and 5.82E−01 to 9.35E−04 for Children and Adult respectively. The level of cancer risk falls above the threshold values (10−4–10−6) which US Environmental Protection Agency considered as unacceptable risk. Based on the above findings, it was suggested that environmental management policy should be implemented to decrease the environmental risks.
Waterborne Disease Risk Factors and Intervention Practices: A Review

Waterborne diseases remain a major global public health issue and a great environmental concern and the outbreak is common in African countries. Illness due to waterborne diseases causes morbidity and mortality in less developed countries among children aged below 5 years. This study was aimed at reviewing literature on past and present studies on waterborne diseases, the risk factors as well as the intervention practices. The unavailability of piped water and dependence of rural dwellers on surface waters which are often contaminated with fecal materials are the major causes of the rising prevalence of waterborne diseases. Poor hygienic practices have also been found to play significant role in the spread of waterborne diseases. Besides, poor environmental practices such as lack of sanitation facilities encourages spread of liquid and solid wastes within residential areas contributing to the increasing waterborne illness. Improvements in drinking water, sanitation facilities and hygiene practices in less developed countries have been suggested by many studies as key interventions to reduce waterborne diseases.
Schemes of Scaffolding in Online Education

Scaffolding in learning has been argued to facilitate the students’ progress. As the educational paradigm inevitably shifts into online modes, strategies for scaffolding provision need to be adjusted. This study aimed to understand the nature of the online learning environment and explore the aspects, types, and methods of scaffolding provision in online learning contexts by adopting George's (2008) research method into a qualitative design. The data were collected from experts' opinions and previous studies, as published in reputable international journals, using Education Resources Information Center (https://eric.ed.gov/), Google Scholar (https://scholar.google.com), and Research Gate (https://www.researchgate.net) as the databases. The research result is presented in an informal method. The review reveals that critical aspects of scaffolding are contingency, fading, and transfer of responsibility, which are applicable in synchronous and asynchronous learning with the support provided by peers, teachers, or technology through static or dynamic interaction. Based on its purpose, the four types of scaffolding are procedural, conceptual, metacognitive, and strategic, which can be performed strategically in online contexts through orientation to the course structure, access to resource and tools, critical thinking development, guidance to problem-solving, provisions of hints, sufficient examples, probing questions, and providing constructive feedback. These findings imply the importance of implementing scaffolding strategies in online learning contexts, although further studies need to be conducted to provide more comprehensive
Bibliometric Analysis on Bibliometric-based Ontology Research

ABSTRACT Ontology is one of the most popular topics in information science in recent years. Ontology engineering plays a significant role and has broad application potential in several fields, such as information sharing, system integration and knowledge-based software development. We analyzed the quantity of published literature, literature-related cooperative network and literature co-citation network in the field of ontology using methods such as metrology citation analysis, knowledge graphs, co-citation analysis and with the help of bibliometric knowledge mapping visualization software and database result analysis tools. Ontology-related literature from the core database of Web of Science between 1986 and 2020 was selected as the sample in this paper. The analysis results indicated that two popular research topics in ontology are semantic web and gene ontology. Among them, semantic web is associated with natural language processing, while gene ontology is related to bioinformatics. In order to track research outcomes in ontology, we conducted a bibliometric analysis of ontology studies over the past two and a half decades.
Does Agricultural Support Policy Affect Crop Production in Turkey?

One of the most basic requirements of humanity is the need for nutrition. Therefore, the demand for food products that do not have a substitute for human life is quite heavy. To this end, the agricultural sector becomes prominent to meet the need for nutrition but puts economic units in a great search. In this context, the agricultural sector is an important dynamic of the country’s economies. This study seeks to answer how support and incentives for the agricultural sector affect agricultural crop production. In this context, the ARDL bounds test with a structural break was conducted using Turkey’s 1995-2018 data to determine the effects of agricultural supports on agricultural crop production. According to the analysis results, it was found out that agricultural supports in Turkey positively affect agricultural crop production in both the short and long term.
An Ontology for Standardising Trustworthy AI

Worldwide, there are a multiplicity of parallel activities being undertaken in developing international standards, regulations and individual organisational policies related to AI and its trustworthiness characteristics. The current lack of mappings between these activities presents the danger of a highly fragmented global landscape emerging in AI trustworthiness. This could present society, government and industry with competing standards, regulations and organisational practices that will then serve to undermine rather than build trust in AI. This chapter presents a simple ontology that can be used for checking the consistency and overlap of concepts from different standards, regulations and policies. The concepts in this ontology are grounded in an overview of AI standardisation currently being undertaken in ISO/IEC JTC 1/SC 42 and identifies its project to define an AI management system standard (AIMS or ISO/IEC WD 42001) as the starting point for establishing conceptual mapping between different initiatives. We propose a minimal, high level ontology for the support of conceptual mapping between different documents and show in the first instance how this can help map out the overlaps and gaps between and among SC 42 standards currently under development.
Detecting Idiographic Personality Change

Abstract Personality changes across the lifespan, but strong evidence regarding the mechanisms responsible for personality change remains elusive. Studies of personality change and life events, for example, suggest that personality is difficult to change. But there are two key issues with assessing personality change. First, most change models optimize population-level, not individual-level, effects, which ignores heterogeneity in patterns of change. Second, optimizing change as mean-levels of self-reports fails to incorporate methods for assessing personality dynamics, such as using changes in variances of and correlations in multivariate time series data that often proceed changes in mean-levels, making variance change detection a promising technique for the study of change. Using a sample of N = 388 participants (total N = 21,790) assessed weekly over 60 weeks, we test a permutation-based approach for detecting individual-level personality changes in multivariate time series and compare the results to event-based methods for assessing change. We find that a non-trivial number of participants show change over the course of the year but that there was little association between these change points and life events they experienced. We conclude by highlighting the importance in idiographic and dynamic investigations of change.
Star Formation Rate of the Low Redshift Dwarf Galaxies J080947.50+213717.2 and J151839.94+220514.4

We performed a spectroscopic analysis of two low redshift dwarf galaxies, SDSSJ080947.50+213717.2, and SDSSJ151839.94+220514.4 selected from a catalogue of Paudel et al. 2018. The strong emission lines of the SDSS spectra of both galaxies were studied and the elements responsible were identified for those characteristic lines. The line ratio between Hα and Hβ (Hα/Hβ) for the galaxies SDSSJ080947.50+213717.2 and SDSSJ151839.94+220514.4 was found to be 2.77 and 2.75, respectively, suggesting these are nearly dust free and star forming galaxies. The star formation rate of the galaxies SDSSJ080947.50+213717.2 and SDSSJ151839.94+220514.4 was found to be 0.0232 M☉yr -1 and 0.05221 M☉yr -1 , respectively. The ratio between NII and Hα was used to calculate the emission line metallicity, which was found to be 8.13 dex and 8.46 dex for the galaxies SDSSJ080947.50+213717.2 and SDSSJ151839.94+220514.4, respectively. From the comparison of our findings with the previous studies, slightly lower star formation rate than normal galaxies were noticed. The metallicity value for both of the galaxies were positioned in the group of low-surface-brightness galaxies of Bargvell's dwarfs.
Behind the trend of Englishing the business names in Aceh, Indonesia: A postcolonial analysis

This study critically analyzes the recent trend of Englishing shop names in Aceh province. Borrowing Bhabha’s postcolonial theory, this study attempted to uncover the shop owners’ perceptions of privileging English and marginalizing local languages, even though their customers are mostly local. Data collection was by taking pictures and interviewing 20 owners of the shops, four females and 16 males. Results show that the 120 shop names in Banda Aceh and surrounding it are in English, modified English and Indonesian ordering, hybridized English and Indonesian ordering, hybridized English Acehnese language and English, English and English ordering, and mixed owner’s names and English ordering. They voluntarily mimicked the Western culture by using English names because they believe that English is marketable, modern, practical, flexible, familiar, and short for shop branding, while the local language looks not modern, unpractical, and weird. In conclusion, most shop owners in the two districts in Aceh negotiate the Western hegemony for the economic benefits.
Extensive vertebrate tracksite from the Upper Red Formation (middle–late Miocene), west Zanjan, northwestern Iran

Abstract. An extensive vertebrate tracksite from the middle–late Miocene Upper Red Formation in western Zanjan Province, northwestern Iran, provides new records of paleobiogeographical significance. These are records of common footprints of felids referred to as Felipeda lynxi Panin and Avram, canids referred to as Canipeda longigriffa Panin and Avram and less common bird footprints referred to as Iranipeda abeli Lambrecht. The Canipeda record establishes the late Miocene presence of canids on the Iranian Plateau as part of the Eurasia-wide “Eucyon event”. The Felipeda footprints are consistent with body fossil and footprint records elsewhere in Eurasia that indicate a widespread distribution of felids by late Miocene time. An unusual trace associated with the footprints is a large, shallow grazing or locomotion trace similar to Megaplanolites in some features but distinctive in various features and its occurrence in nonmarine facies, and it will be the subject of further study.
