Authors: Ding Zhiqiang , Liu Yue , Fu Yong , Chen Feng , Chen Zhangpei , Hu Jianshe
Published: April 2020

In recent years, industrial contaminants and especially organic pollutions have been threatening both environmental safety and human health. Particularly, dibutyl phthalate (DBP) has been considered as one of the major hazardous contaminants due to its widespread production and ecological toxicities. Consequently, reliable methods toward the efficient and environmentally benign degradation of DBP in wastewater would be very desirable. To this end, a novel magnetically separable porous TiO2/Ag composite photocatalyst with magnetic Fe3O4 particles as the core was developed and successfully introduced to the photocatalytic degradation of DBP under visible irradiation with a fluorescent lamp. The presented work describes the grafting of Ag co-doped TiO2 composite on the silica-modified porous Fe3O4 magnetic particles with a simple and inexpensive chemical co-precipitation method. Through the investigation of the influencing factors including photocatalyst dosage, initial concentration of DBP, solution pH, and H2O2 content, we found that the degradation efficiency could reach 74%. The photodegradation recovery experiment showed that the degradation efficiency of this photocatalyst remained almost the same after five times of reuse. In addition, a plausible degradation process was also proposed involving the attack of active hydroxyl radicals generated from this photocatalysis system and production of the corresponding intermediates of butyl phthalate, diethyl phthalate, dipropyl phthalate, methyl benzoate, and benzoic acid.

Published: April 2020

Aim. To study the ultrasonographic parameters of segmental function and mechanics of the aorta and carotid arteries in healthy infants.Methods. We observed 114 healthy infants (age range, 1–12 months; boys 52.6%; mean body surface area (BSA): 0.35 ± 0.8 m2). Echocardiography was performed with an Acuson S 2000 (Siemens Medical Systems, Mountain View, CA, USA) using vector velocity imaging (VVI). The following parameters were estimated at the level of the ascending and abdominal aorta and in the common carotid arteries (CCA): maximum and minimum diameters (mm); circumferential strain (CS, %) and circumferential strain rate (CSR, s-1); fraction area change (FAC, %); arterial stiffness (β2).Results. The maximum and minimum diameters of the examined segments of the aorta and CCA, FAC of the aorta and CCA, CS and CSR of the aorta and CCA showed a correlation with BSA, age, LV stroke index, and LV myocardial mass index. None of the estimated parameters showed a correlation with sex, arterial blood pressure, or left ventricular ejection fraction. The highest CS values were found in CCA 7.85 ± 2.8% [compared with 5.4 ± 0.98% (p = 0.0001) in the ascending aorta and 6.7 ± 1.8 % (p = 0.03) in the abdominal aorta). CSR in the CCA (0.84 ± 0.22 s-1) was significantly higher than that at the abdominal aorta level (0.67 ± 0.24 s-1, p = 0.001), but lower than that in the ascending aorta (1.3 ± 0.3 s-1, p = 0.00001).Conclusion. The parameters of segmental function of the aorta and common carotid artery obtained in our research can serve as normative reference for children in the first year of life. The functional parameters of the aorta and common carotid artery depend on the age and BSA.

Фотолюминесценция композиций полиметилметакрилат/(Zn, Cu, Ag)S : Eu-=SUP=-3+-=/SUP=-
Authors: Смагин В.П. , Затонская Л.В. , Ильина Е.Г. , Харнутова Е.П.
Published: April 2020

Luminescent nanoscale particles (quantum dots) (Zn,Cu,Ag)S:Eu3+ were synthesized during decomposition of thioacetamide complexes of metals in a methylmethacrylate medium during block polymerization under heating. The formation of quantum dots is confirmed by the corresponding band in the optical absorption spectrum of polymer compositions. Photoluminescence of PMMA/(Zn,Cu,Ag)S:Eu3+ compositions is manifested as a complex band associated with defects in the crystal structure formed when ZnS was doped with copper and silver ions, and a set of narrow bands of luminescence of Eu3+ ions. Luminescence excitation occurs as a result of inter-zone transitions and electron transitions from the valence band to the ZnS defect levels, and self-absorption of energy by Eu3+ ions. The relationship of ions Eu3+ particles of ZnS is confirmed by the dependence of the intensity of the broadband luminescence of ZnS with increasing concentration of ions Eu3+ and an increase in intensity narrow-band luminescence of ions Eu3+ as a result of energy transfer from levels of doped ZnS crystals on the energy levels of the ions Eu3+.

Published: April 2020

Features of the polymorphic transformations in iron of different purity and zirconium iodide were studied using high-resolution calorimetry methods. It has been suggested that the polymorphic transformations in zirconium, in contrast to the polymorphic transformations in iron, were controlled by two mechanisms: diffusion-free and diffusion. The relationship between them depends on the rate of thermal cycling and the thermal background of zirconium.

Authors: Henderson Brittney R , Flaherty Carina M , Floyd G Chandler , You Jack , Xiao Rui , Bryant-Stephens Tyra C , Miller Victoria A , Feudtner Chris , Kenyon Chén Collin
Published: April 2020

Background

Poor adherence to inhaled corticosteroid medications for children with high-risk asthma is both well documented and poorly understood. It has a disproportionate prevalence and impact on children of minority demographics in urban settings. Financial incentives have been shown to be a compelling method to engage those in a high-risk asthma population, but whether adherence can be maintained by offering financial incentives and how these incentives can be used to sustain high adherence are unknown.

Objective

The aim of this study is to determine the marginal effects of a financial incentive–based intervention on inhaled corticosteroid adherence, health care system use, and costs.

Methods

Participants include children aged 5 to 12 years who have had either at least two hospitalizations or one hospitalization and one emergency department visit for asthma in the year prior to their enrollment (and their caregivers). Participants are given an electronic inhaler sensor in order to track their medication use over a period of 7 months. After a 1-month period of observation, participants are randomized to 1 of 3 arms for a 3-month period. Participants in arm 1 receive daily text message reminders, feedback, and gain–framed, nominal financial incentives; participants in arm 2 receive daily text message reminders and feedback only, and participants in arm 3 receive no reminders, feedback, or incentives. All participants are subsequently observed for an additional 3-month period with no reminders, feedback, or incentives to assess whether any sustained effects are apparent.

Results

Study enrollment began in September 2019 with a target sample size of N=125 children. As of June 2020, 61 children have been enrolled. Data collection is estimated to be completed in June 2022, and analyses will be completed by June 2023.

Conclusions

This study will provide data that will help to determine whether a financial incentive–based mobile health intervention for promoting inhaled corticosteroid use can be effective in patients with high-risk asthma over longer periods.

FoodScan: A New mHealth App for Food Monitoring through the Analysis of Purchase Groceries Receipts (Preprint)
Authors: Sainz-De-Abajo Beatriz , García-Alonso José Manuel , Berrocal-Olmeda José Javier , Laso-Mangas Sergio , de la Torre-Díez Isabel
Published: April 2020

BACKGROUND

For the mobile device market there is a large number of applications that allow the control of food to lose weight and manage a healthy diet. However, the vast majority of these apps consume a lot of time by having to introduce food, one by one, for that control.

OBJECTIVE

This work presents a new Android application, FoodScan, aimed at people over 70 and their caregivers, specially those from rural environments or with limited technical knowledge, to manage their food from the items that appear on their grocery receipts in a simple and dynamic way, avoiding the obligation to introduce one by one those foods. The user can scan the grocery receipts, keeping a record of what they have purchased. The application will generate recommendations on what you should eat to follow a healthy diet according to the parameters set. Additionally, everything runs without the need to be connected to the Internet. Data management is done locally and, therefore, personal data is not sent to a remote server to be analyzed, improving the privacy of the proposed solution.

METHODS

Prior to development, different algorithms were tested to expedite the introduction of food into the application and the most suitable for the FoodScan application was selected. Likewise, several options were taken into account to create the knowledge base of food, taking into account dietary recommendations for people over 70 years.

RESULTS

FoodScan stands out for having a friendly and intuitive interface and ease of use. In addition to the development of the application, an evaluation of the level of satisfaction by the users was carried out. The results of the satisfaction survey highlight the ease of installation (93% think it is easy and very easy) and FoodScan handling (66% believe it is easy and very easy). This contributes to loyalty to users. The fact of a simple handling allows its use among people over 70 years, who usually do not have skills with the new technologies, to control healthy habits in their diet.

CONCLUSIONS

When developing an application, it is convenient to take into account the user's needs to adapt to their circumstances. Only if the users perceive the application as simple, friendly and does not take a long time to use, will they be loyal and not abandon their control of the diet.

Authors: ARYATI WIDYA DWI , AZKA KHUSNA MILLATI , MUN’IM ABDUL
Published: April 2020

Objective: Melinjo (Gnetum gnemon L.) seeds are known to contain resveratrol, which are classified as a phenolic compound of the stilbenoid. Melinjoseeds have high water content, making them unstable to be stored for prolonged periods with open packaging at room temperature. The present studyaimed to explore the use of ultrasonic-assisted extraction with a betaine-based natural deep eutectic solvent (NADES) for resveratrol extraction fromirradiated melinjo seeds.Methods: The best betaine-based NADES component was identified among betaine-urea, betaine-lactic acid, and betaine-malic acid. Optimization ofextraction methods was performed using the best NADES and extraction variables such as time of extraction, water percentage, and sample: solventratio. The outcome of extraction was evaluated by measuring resveratrol content using high-performance liquid chromatography and the results wereanalyzed using response surface methodology.Results: The best betaine-based NADES was found to be betaine-lactic acid, yielding a resveratrol content of 0.3344 mg/g powder. The optimumextraction was achieved in 10 min with 60% water and a sample: solvent ratio of 1:10, yielding a resveratrol content of 0.227 mg/g powder.Conclusion: Betaine-based NADES can be purposed as an alternative solvent for resveratrol extraction from irradiated melinjo seeds.

Published: April 2020

Background: Dipeptidyl peptidase-4 (DPP4) is an enzyme responsible for inactivating the hormone incretin, which potentiates insulin secretion andglucagon inhibition; inhibitors of DPP4 are used as therapeutic drugs for type-2 diabetes.Objective: In this study, we evaluated potential DPP4 inhibitors from the Indonesian Medicinal Plants Database using an in silico approach.Methods: A ligand-based pharmacophore model was used for screening the database using LigandScout 4.2. This model was validated using severalparameters of enrichment metrics, including receiver operating characteristics, area under curve (AUC), and enrichment factor (EF). Hit compoundswere also docked with DPP4 to calculate the free binding energy and analyze the interaction between the ligand and DPP4. In addition, bioavailabilityand medicinal chemistry predictions were performed for the hit compounds.Results: The best pharmacophore model demonstrated AUC100% and EF1% values of 0.82 and 33.8, respectively. The pharmacophore features of themodel included hydrogen bond donors, hydrogen bonds, hydrophobic interactions, and positive ionization areas. Based on our results of virtualscreening and molecular docking, six hit compounds were ultimately identified, namely, L-noradrenaline, octopamine, Nb-demethylechitamine, alliin,isoalliin, and subaphylline.Conclusion: Collectively, our findings indicate that subaphylline is the most promising compound for further studies, including in vitro and in vivoexperiments and those focused on molecular dynamics and structural modification.

Being similar: other-identification during fieldwork
Authors: Abimbola Olumide
Published: April 2020

The paper discusses instances of other-identification when the other is similar to the self, and when difference is brought out by the similar. In a situation that is explicitly legal, but whose legality is predicated on a form of illegality, conducting fieldwork might be a bit challenging. The fact that the fieldworker is a native of sorts helps overcome some difficulties, while at the same time throwing up others. This paper discusses some forms of such identifications and difficulties, and the constant negotiation that is present in the identification process.
Talking drums and ethical conundrums
Authors: Goldstein Ruth
Published: April 2020

Malian women and children represent the poorest as well as the most difficult to reach through written media. The interrelated practices of dancing, drumming, and storytelling transmit history, cultural beliefs, and current events for people who do not read and write. Researchers in the social sciences and officials for international aid organizations struggle with the circulation and reception of public health literature. They now recognize that native non-governmental organizations with staff that are fluent not only in the native languages but also in the social mores, better communicate with under-served populations through means other than billboards, pamphlets, or power-point presentations. The body, in both a general Western and Malian tradition, plays a particular role in how we come to know the world. This paper describes research conducted in Mali on female circumcision with international aid organizations, native NGOs, and independent human rights activists. Three interconnected areas form a triangular framework: how different research methods like dancing, drumming, storytelling, and soccer can offer valuable phenomenological insights to lived experience; the ethics of learning and listening to these various voices that transmit sexual health knowledge; and the ethics of engaging and disseminating such knowledge. The talking drums elicit new ways of seeing, being, and listening along with ethical ethnographic conundrums.

Caring Enough to Wait: Bureaucratic Care and Waiting Time Standards in an NHS clinic for Adults with ADHD
Authors: Jousselin Claude Marc
Published: April 2020

The drive in the UK National Health Service (NHS) to reduce the amount of time patients spend waiting to be assessed is generally accepted to be of positive benefit to all and remains at the top of the UK political agenda. In this article I examine how waiting is also done by administrative and clinical staff by drawing on ethnographic observations made in an Attention Deficit Hyperactivity Disorder (ADHD) diagnostic NHS clinic for adults. According to the criteria in the American Diagnostic and Statistical Manual (DSM), pervasive forgetfulness is recognised as part of ADHD symptoms, and in its persistence through consecutive life stages, it can become seriously disabling. Thus individuals referred to a clinic may repeatedly miss their appointments and delay their assessment and treatment. In this article, I look at how an NHS policy that facilitated the rescheduling of missed appointments due to the 'nature of illness' was superseded by the desire to shorten waiting lists. Thus two competing NHS narratives, which I term ‘the time to care’ and ‘the speed of access,’ became enacted in the administrative organisation of the clinic, resulting in the potential abandonment of the very patients who were meant to benefit from such change.
Circulating Retinol-Binding Protein 4 Is Inversely Associated With Pancreatic β-Cell Function Across the Spectrum of Glycemia
Authors: Huang Rong , Yin Songping , Ye Yongxin , Chen Nixuan , Luo Shiyun , Xia Min , Zhao Lina
Published: April 2020

OBJECTIVE

The aim of this study was to examine the association of circulating retinol-binding protein 4 (RBP4) levels with β-cell function across the spectrum of glucose tolerance from normal to overt type 2 diabetes.

RESEARCH DESIGN AND METHODS

A total of 291 subjects aged 35–60 years with normal glucose tolerance (NGT), newly diagnosed impaired fasting glucose or glucose tolerance (IFG/IGT), or type 2 diabetes were screened by a standard 2-h oral glucose tolerance test (OGTT) with the use of traditional measures to evaluate β-cell function. From these participants, 74 subjects were recruited for an oral minimal model test, and β-cell function was assessed with model-derived indices. Circulating RBP4 levels were measured by a commercially available ELISA kit.

RESULTS

Circulating RBP4 levels were significantly and inversely correlated with β-cell function indicated by the Stumvoll first-phase and second-phase insulin secretion indices, but not with HOMA of β-cell function, calculated from the 2-h OGTT in 291 subjects across the spectrum of glycemia. The inverse association was also observed in subjects involved in the oral minimal model test with β-cell function assessed by both direct measures and model-derived measures, after adjustment for potential confounders. Moreover, RBP4 emerged as an independent factor of the disposition index-total insulin secretion.

CONCLUSIONS

Circulating RBP4 levels are inversely and independently correlated with β-cell function across the spectrum of glycemia, providing another possible explanation of the linkage between RBP4 and the pathogenesis of type 2 diabetes.

An Event-based Local Action Paradigm to Improve Energy Efficiency in Queriable Wireless Sensor Actuator Networks
Authors: Bergelt René , Hardt Wolfram
Published: April 2020

Wireless sensor networks (WSN) are deployed in a multitude of applications both in industrial and academic fields. In recent years, due to the emerge of Internet of Things (IoT) technologies and Vehicle2X communication scenarios, novel challenges for wireless sensor network platforms - regarding hardware and software - arose. Thus, challenges known from big data processing have reached the WSN scope and consequently approaches and methods have been devised to handle these. One such approach is queriable wireless sensor networks which enable their users the specification of sensing tasks in a declarative way without the need to re-program nodes in case the application requirements change. As many current WSN applications feature active parts with which nodes can directly influence their environment, the term wireless sensor actuator networks (WSAN) has been coined, setting such networks apart from solely passively measuring networks.In this article, we will present a short introduction to big data processing in wireless sensor networks which motivates the usage of queriable networks. We will show that in order to enable a WSAN to carry out actions energy-efficiently and in a timely manner, an event-based action model is favorable. Additionally, we will demonstrate how such an event system can be used to improve sub query performance in WSNs. We conclude with an evaluation regarding the benefit of combining this approach with wake-up receiver technologies based on a qualitative energy efficiency definition for WSN.

The Effects Of Environmental Problem-based Learning Method On Malaysian Primary ESL Learners’ Vocabulary Achievement
Authors: Chai Zachary Farouk , Swanto Suyansah Bin
Published: April 2020

Environmental education has long been introduced as early as the 18th century in western countries, but in Malaysia, it still can be considered as a new start in the year 1979. In relation to this, various programs have been conducted by the government to produce literate individuals that are aware of and concern of environmental issues. In primary English education, there are a few topics on the environment that should be taught by teachers, and environmental education is also considered as a cross-curricular subject. The present study aimed to investigate the effects of environmental problem-based learning (PBL) on Malaysian primary school learners' vocabulary achievement. Environmental PBL is an instructional method that provides learners the opportunities to learn cooperatively in groups to find solutions to any problem. This study employed experimental design, which involved 20 learners that came from an intermediate level of English proficiency. They were randomly divided into experimental group and control group. The experimental group was treated with environmental PBL in learning new vocabulary, while the other group was taught using the conventional memorisation method. A set of vocabulary test (pre and post) was used to measure learners' vocabulary achievement and the data were analysed by using independent sample t-test. From the data, it was found out that the learners who were taught by using environmental PBL improved their vocabulary acquisition significantly as being compared to the control group based on the means of marks obtained by the research participants in the experimental group with 12.80 and the mean achieved by the control group with 6.20. Next, this study also showed how environmental PBL helped the experimental group in learning vocabulary based on their orientations which included two themes (effectiveness and participation). Hence, it is suggested that English teachers should use environmental PBL as an effective method of teaching vocabulary to young learners.

Financing infrastructure in Asia through bonds and capital markets
Authors: Ray Shubhomoy , Bisbey Jyoti
Published: April 2020

The project finance scenario has changed significantly around the world after the 2008 financial crisis and following the subsequent Basel III recommendations. Project finance loans from commercial banks and financial institutions have largely dried up, leaving it mostly to the export credit agencies and the bilateral and multilateral development banks to provide the institutional credit. Unfortunately, those sources are not enough, given the huge needs for construction of new infrastructure and renovation of the old ones across Asia, Africa and Latin America. The need for capital markets, through market listed financial products across asset class, unlocking a large part of domestic and corporate savings, has never been felt as strongly before. This article seeks to analyze the development story of various Asian capital markets and examine financial products, which have succeeded in their short history in receiving investor interest. The article also delves into the challenges to market development, policy imperatives and the issues relating to market liquidity and credit rating, which are the most significant influencers for public market float and investor interest.
An estimation of the industrial production dynamic in the MERCOSUR countries using the Markov switching model
Authors: Infante Saba , Gómez Edward , Sánchez Luis , Hernández Aracelis
Published: April 2020

In this work the methodology applied is based on Bayesian statistical methods inspired by Markov chain Monte Carlo sampling schemes, which simplifies the estimation and prediction process of the Markov switching model. The general objective of this study is to determine simultaneously: non-linearity, structural changes, asymmetries and outliers that are characteristics present in many financial series. The methodology is empirically illustrated using series that measure the annual growth rate of industrial
production in the MERCOSUR countries. The sampling algorithm is implemented to estimate the parameters of the model. The parameters were estimated in terms of expected values a posteriori and standard deviations a posteriori. Three criteria are used to assess the prediction model: square root of the mean quadratic error (RSME), the Diebold-Mariano (DM) test and the TRC statistical test. These measures of goodness-of-fit show, that the estimates have small errors. The execution time of the algorithm is calculated, observing high performance. As a result of the analysis of the data, it is concluded that there is no reduction of economic volatility and no reduction in the depth of economic cycles. At the breakpoints, atypical values and non-linearity in the data are observed. It also shows that there are no common economic cycles for the countries analyzed.
Juegos con utilidades multidimensionales y responsabilidad social de las empresas
Authors: Zapata Reina Asunción
Published: April 2020

This paper provides an innovative analysis of strategic models with multidimensional util-
ities. A wide range of problems of economic nature can be modeled more realistically by this setting, in which several objectives must be taken into account. The traditional treatment of economic models is characterized by the principle of individual rationality. However, the evidence shows that people do follow not only their own interests, but also they often worry about the welfare of others. We analyse Cournot's model of oligopoly by considering a vector utility function and with a perspective of the firm based on principles of social responsibility. We conclude that firms can achieve equilibria in which the social cost is reduced.

Published: April 2020

The general objective is to estimate the probability for a Mexican state to improve its position in the Doing Business Ranking. After selecting the variables with a larger or more relevant significance in terms of goodness-and-fit tests, the logistic regression method is applied for its binary characteristic, interpreted for this study as a change or no change of position in the ranking throughout different periods. The probability is estimated for a certain state of Mexico to improve its position. Twenty-eight trials were developed, enabling to acknowledge in which conditions of cost, time and number of procedures there is an improvement in the position. The results provide elements to suggest or recommend adjustments in the variables considered in the Ranking, discriminating changes in those with less significance.

The purpose of the present research is to explore the effect of brand image on brand loyalty and brand commitment to national and private label brands. Data was collected through a field survey via the store-intercept method. To test the research hypotheses, we used two samples, which implied the collection of usable 528 questionnaires. Confirmatory factor analysis was used to test the reliability, convergent, and discriminant validity of the constructs of interest. The structural equation modeling (SEM) technique was employed to analyze the effect of brand image on brand loyalty and brand commitment. Also, group comparisons were made between national brands and private label brands, using structural equation modeling. This study reveals that brand image has a significant positive effect on brand loyalty and brand commitment, both for national and private label brands. Moreover, it was found that the effect of brand image on brand commitment is stronger for national brands than for private label brands. The present study provides marketing managers of national brands and private label brands some insights into how to spur brand loyalty and commitment by establishing a favorable brand image.
