La discipline économique peut-elle être une science ?
Authors: Boyer Robert
Published: December 2022

L’incapacité de la discipline économique à anticiper et surtout expliquer la succession des crises qui culmine avec celle ouverte en 2008 n’est pas un accident. C’est l’expression des faiblesses méthodologique et épistémologique de toute une profession. Refus de l’historicité des catégories et des entités de l’économie, confusion entre théorie et modèles, balkanisation en une multitude de paradigmes concurrents et souvent contradictoires, vaine recherche de fondements microéconomiques à la macroéconomie au mépris de la pertinence empirique. En réponse à ces échecs, triomphent aujourd’hui les techniques d’analyse des masses de données, tout particulièrement financières, sans claire perspective de refondation théorique. La transnationalisation et l’extrême spécialisation de la discipline expliquent tant la reconnaissance professionnelle des économistes que leur incapacité à construire une science en bonne et due forme. D’éminents Prix Nobel ont souligné qu’une telle impasse devrait être surmontée par un effort de réflexivité collective sur les incitations et les processus qui façonnent la profession et orientent les programmes de recherche. La multiplication de lieux de confrontation entre divers paradigmes pourrait favoriser l’émergence d’une discipline modeste, auxiliaire des citoyens et des choix politiques.

GIS-based analysis of doline density on Miljevci karst plateau (Croatia)
Authors: Lončar Nina , Grcić Ivana
Published: December 2022

The doline density and their spatial distribution analysis is one of the methods used for karst relief morphostructural analysis. We present the results of morphometric features, doline spatial distribution and their relationship on Miljevci karst plateau based on digital elevation model (DEM). Altogether, 286 dolines were mapped in the study area. The doline density analysis has been applied. The results show that the doline spatial distribution is clustered. Two larger areas with densities of 30 and 34 dolines/km2 are determined. Their distribution along the river canyons could indicate the existence of a palaeodrainage network. The strongest link between the doline density and topography is with inclination and vertical relief dissection, whereas the number of dolines decreases with an increase of slope inclination and relative relief. Such distribution confirms the suitability of karstic plateaus without active drainage for doline formation.

Updating STACK Potential Response Trees Based on Separated Concerns
Authors: Alarfaj Maryam , Sangwin Chris
Published: December 2022

The STACK system is a computer aided assessment package for mathematics. STACK questions include full algebraic input with validation.  Feedback is provided to students using "potential response trees", written by the teacher for each question. In this research, we are updating STACK potential response tree based on students' concerns in learning induction proofs. We have identified a specific misconception in learning mathematical induction from prior educational research, designed STACK question to test if students exhibit this misconception, and then illustrated how we updated STACK potential response tree based on this misconception. One main goal of separating concerns is to understand students’ responses and evaluate the question itself from an academic prospective and ultimately to improve the questions for future years. In addition, one of the contributions of this study is to improve our general understanding of how to design and use STACK potential response trees.

Published: December 2022

The spread of COVID-19 has brought negative impacts on the life and study of college students and thus aggravated their mental stress in this environment. Existing research has focused more on the status quo of the problem while having ignored its process variability, and there is no research on the correlation between the mental stress of college students and their learning initiative during the outbreak of COVID-19. To this end, this paper conducts an analysis of the correlation between the mental stress of college students and their learning initiative during the outbreak of COVID-19. In-depth analysis was carried out by the factor analysis method in SPSS, and an evaluation model was built for the mental stress of college students during the outbreak of COVID-19 based on four stressors, with the process of how to obtain the evaluation results given. The grey correlation analysis method was used to quantitatively analyze the correlation between the mental stress of college students and their learning initiative during the outbreak of COVID-19, that is, the factors affecting college students’ learning initiative during the outbreak of COVID-19 were investigated through the grey correlation analysis. Finally, the relevant experimental results were given.

Authors: Jia Ligang
Published: December 2022

This paper explores the establishment of the effectiveness evaluation index system for students’ learning under blended learning environment, so as to provide some theoretical reference and guidance for the evaluation of the effect of students’ learning in blended environment. In current studies, there are few quantitative analyses on the application cases or teaching practice, and there is also a lack of evaluation studies on the students as the main body of the learning process. Therefore, this paper carries out a study on the clustering analysis of the evaluation data on students’ learning in blended environment, displaying the learning effect satisfaction model for students under blended learning environment, and providing the idea of constructing a learning effect evaluation model accordingly. This paper characterizes the learning effect of students at each stage in the form of sets and formulates evaluation index system. The analytic hierarchy process-grey clustering evaluation of students’ learning effect in blended environment is carried out. On the basis of analytic hierarchy process, the evaluation index weight is determined and the evaluation grade is fixed based on the grey clustering analysis. The experimental results verify the effectiveness of the evaluation model.

Published: December 2022

Industries such as electroplating, mining etc. produce wastewater that, as it includes various heavy metals such as lead, cadmium, has a potential threat to our environment. If this wastewater is left untreated, soil and water supplies would be polluted. The release of heavy metals into the natural world, has resulted in a number of heavy metals that can cause serious harm to humans and marine life even at trace levels. Thus, this research address the synthesis of oil palm frond (OPF) based mesoporous silica nanoparticle (MSN) which intended for the removal of heavy metal. The MSN were synthesised from OPF via sol-gel method and later utilised as adsorbent to removed lead (Pb) from the aqueous solution. The FTIR results of OPF-based MSN exhibit similar peak with commercially available silica. The MSN adsorbent was then investigated for Pb removal under different parameter including pH, contact time, dosage, concentration, and temperature and analysed using Atomic Absorption Spectroscopy (AAS). The optimum condition was obtained at pH 7, 45 mins of contact time, 0.4 g/L adsorbent dosage under 10 ppm of Pb concentration at 303 K that aid in enhancing Pb removal by the OPF-based MSN. At this condition, MSN successfully removed up to 89% of Pb in aqueous solution with adsorption capacity of the adsorbent is within the range of 22.3 mg/g. This result demonstrates the potential application of MSN from OPF as an adsorbent in Pb removal from wastewater.

Published: December 2022

Methylene orange (MO) is a toxic fabric dye to the environment and health. Therefore, some actions are needed to overcome this problem. The advanced oxidation process (AOPs), especially Fenton by hydrogen peroxide (H2O2) and CaO/Fe2O3, is a powerful method to be implemented. In this experiment, the CaO/Fe2O3 was prepared by impregnation using CaO derived from chicken eggshell waste and Fe(NO3)3⸳9H2O powder with calcination temperature variations of 600, 700, and 800°C. Then, the characterization of materials was identified by Fourier Transform Infrared (FTIR), X-ray diffractometer (XRD), scanning electron microscope (SEM), and electron dispersive spectroscopy (EDS), followed by a visual observation decolorization test. Using FTIR and XRD, CaO has been successfully obtained through the calcination process. Fe2O3 was also detected, indicating impregnated into CaO support. The particle size ranges from 37–48 mm, appearing irregular in shape. Finally, the fastest decolorization of MO resulted in CaO/Fe2O3 with 800°C of calcination temperature. These results indicated that CaO/Fe2O3 nanocomposite catalyst is the potential to reduce liquid pollutants and utilize a waste resource.

Published: December 2022

The aim of this work was to investigate the influences of different concentrations of Ag3PO4 aqueous dispersion by measuring the bacteriostatic characteristic against bacteria E. coli. The Ag3PO4 particles were successfully synthesized by precipitation method. Then, the morphological, structural and chemical compositional analyses were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR), respectively. All these analyses confirmed the formation of Ag3PO4 particles with the shape of nearly spherical with a size of 100 – 700 nm. Meanwhile, Kirby-Bauer disk diffusion susceptibility test was chosen to determine the sensitivity of E. coli to antibacterial compounds in Ag3PO4 particles. The results showed that the antibacterial ability was significantly improved by increasing the concentration of Ag3PO4 aqueous dispersion, and the best concentration was 600 mg /mL. This study suggested that Ag3PO4 particles can be exploited as an effective candidate for antibacterial agents.

Municipal solid waste landfills are major sources of environmental pollution. This study evaluated heavy metal concentrations in soils around Pulau Burung Landfill, Penang, Malaysia, to determine the pollution potential of a landfill. Soil samples were collected at depths of 0–20 cm (top), 20–40 cm (center) and 40–60 cm (bottom) around the landfill and at a control site and characterized for various properties and concentrations of Lead (Pb) and Zinc (Zn). Samples of daily soil cover, collected from the same sites where soil samples were collected, were also analyzed for several of heavy metals analysis. The soils were silty sand, mostly acidic (4.45) with low organic matter content (0.41%) and cation exchange capacity (3.15-3.19 meq/100 g). Other basic physico-chemical and adsorption properties were conducted on soil indicated that soil alone is not effective to be used in the landfill to support the pollutant for a long time. Heavy metals concentrations (as background data) in the soils followed the order Iron (Fe) > Zinc (Zn) > Manganese (Mn) > Lead (Pb) > Arsenic (As) > Chromium (Cr) > Cadmium (Cd) > Copper (Cu) > Nickle (Ni) with samples from around the landfill having higher concentrations especially Iron, (Fe) and Zinc, (Zn). For soil profile contribution, heavy metal enrichment was highest at a depth of 40–60 cm. In short, soil alone cannot retain and minimize the migration of heavy metals in landfill based on the results of this study including removal efficiency test. Monitoring of environments around active landfills needs to be ongoing to mitigate negative impacts on humans and the environment.

Published: December 2022

This study aims to determine the optimal conditions of acid-activated clay adsorbent in adsorption of Pb2+ metal ions. Clay was taken around East Kalimantan, Karang Joang. This adsorbent was prepared by mixing clay into a solution of KMnO4, H2SO4 and HCl successively, and stirred for 4 hours at a temperature of 80°C. The morphology and active groups of the adsorbent were analyzed using BET and FTIR. The variables of this study were the mass of the adsorbent 0.1, 0.3 and 0.5 grams and the contact time of 5, 30 and 55 minutes. Adsorption capacity of this adsorbent was analyzed using Atomic Absorption Spectrophotometry (AAS). The results of this study indicate that the optimum mass of adsorbent is 0.1 g, and contact time is 30 minutes. Adsorption capacity of Pb2+ metal ions by acid-activated clay adsorbent at the optimum condition of 0.1 gram was 23,585 mg/g and adsorption energy was 2,338 kJ/mol. Meanwhile, at the optimum condition for 30 minutes, the adsorption capacity was 0.771 mg/L, and the adsorption energy was 2.895 kJ/mol. So that the adsorption process in this study can be known, namely physical adsorption because the adsorption energy value is less than 40 kJ/mol.

Published: December 2022

One of the most dangerous pollutants frequently found in environment are heavy metal ions. Industrial effluents especially those rich in heavy metals are potential pollution source for aquatic environment. In this study, magnetic modification of activated natural zeolite (MZ) was prepared and then used as host for immobilization of dithizone in less toxic alkaline medium. The obtained material, dithizone-immobilized magnetic zeolite (MZD) was applied as adsorbents for adsorption of heavy metal Cd (II) ion in water. The mechanism of interaction between the adsorbent and Cd (II) ion was studied by sequential desorption experiments of Cd (II) ion using different solvents. The adsorbents were characterized by FTIR and XRD to confirm the successful magnetization and immobilization of dithizone on the activated natural zeolite. Results of adsorption study shows that adsorption capacity of MZ and MZD adsorbents towards Cd (II) ion are 17.8 and 37.5 mg g-1, respectively. The adsorption of Cd (II) on both adsorbents is best described by pseudo 2nd order reaction and follow Langmuir isotherm adsorption model. Sequential desorption experiments has revealed that Cd (II) adsorption on MZ is dominated by electrostatic interaction while that on MZD is mostly occurred through complexation. The synthesized materials is promising to be used as adsorbent of heavy metals because it can magnetically be separated and selectively adsorbed heavy metals with higher capacity.
Performance of Thermally Stable Diamond Composite as Rock Cutting Tips under Varied Resultant Force Angle
Authors: Sun Yong , Li Xing Sheng , Guo Hua
Published: December 2022

Various studies have been carried out to understand the properties and the performance of Thermally Stable Diamond Composite (TSDC) when it is used as the rock cutting tools. Existing studies focused on the influences of uncertain TSDC material properties, and randomly varied rock strengths and thickness on the failure probability of cutting tips made of TSDC. It is found that the compressive strength of TSDC cutting tips is much higher than their tensile strength. As a result, the ability of a TSDC cutting tip to bear the resultant force applied along its axis is much greater than its ability to bear the resultant force perpendicular to its axis. However, the resultant angle during rock cutting processes varies greatly. This study focuses on the investigation of the impact of varied resultant force angles on the performance and failure characteristics of TSDC as a rock cutting tip using Monte Carlo simulations. The results show that the varied resultant angle can significantly influence the failure characteristics of the TSDC cutting tip with a fixed attack angle.

Published: December 2022

BACKGROUND:

Iron deficiency anemia (IDA) is one of the most common anemias, especially in children 4–23 months. Therefore, prophylaxis is necessary to improve iron status as well as reduce IDA in Toddlers. The aim of this study was to compare the efficacy of daily supplementation with ferrous gluconate (FG) and ferrous sulfate (FS) on iron status in toddlers.

MATERIALS AND METHODS:

A total of 120 healthy toddlers were divided randomly into 2 groups at the Amir-Kabir Hospital, Arak, Iran and received FS and FG from March 2020 to December 2020. Iron status was evaluated at baseline and after 6 months of supplementation. The statistical significance of the differences in iron status between FS and FG groups was calculated using Student's t-test and the Pearson' s Chi-square test for qualitative variables. SPSS software (version 16, Chicago, IL, USA) was used for statistical analysis.

RESULTS:

Comparison of iron status of FS and FG groups toddlers at baseline and after 6 months of supplementation showed that there was a significant difference in hemoglobin (Hb) (10.46 vs. 12.45, P = 0.001) and ferritin level (28.08 vs. 59.63, P = 0.001).

CONCLUSIONS:

Although prophylaxis with FG led to a higher Hb and ferritin levels, our study recommended that both FG and FS supplements were effective for prophylactic use in the prevention of IDA. However, FG was more effective than FS because FG group that received FG supplementation indicated a higher Hb and ferritin levels in comparison to the FS group that received FS supplementation.

Authors: JamaliGandomani Sedighe , Taebi Mahboube , Mirghiasi Ali Reza , Nilforoushan Parisa
Published: December 2022

BACKGROUND:

Infertility is a crisis in the life of couples that could affect their relationships. The present study was conducted to evaluate the relation between infertility factors and the quality of marital relationship in infertile couples who were referred to the Fertility and Infertility Center of Isfahan.

MATERIALS AND METHODS:

The present study was conducted cross-sectional on 131 infertile couples who were referred to the Fertility and Infertility Center of Isfahan and had the inclusion criteria and were selected using convenient sampling method. Data gathering tool for the present study was Perceived Relationship Quality Components (PRQC). All the data were analyzed using SPSS software version 21. Analysis was conducted using descriptive and inferential statistics (independent t-test and one-way analysis of variance). The level of significance was set at 0.05 for all the statistical tests.

RESULTS:

The mean score of PRQC for women and men was 84.05 and 88.46, respectively, and their difference was statistically significant. There was a significant relation between the score of PRQC in women (P = 0.028) and men (P = 0.030) with the infertility factor. Results showed that the mean score of perceived quality of different aspects of the marital relationship was significantly lower when the infertility factor was female (P < 0.05). In women aspects of “satisfaction” (P = 0.024) and “commitment” (P = 0.011) and in men aspect of “love” (P = 0.004) from the perceived aspects of relationship had a significant relation with the infertility factor.

CONCLUSIONS:

Perceived quality of different aspects of marital relationship had a significant relation with infertility factor in infertile couples. Results of the present study showed that when infertility had female causes, the quality of relationship was more affected. Therefore, in infertility counseling, simultaneous counseling for both spouses with emphasis on women, along with treatments, should be considered.

Cesarean section or normal vaginal delivery
Authors: Saraf Tanisha Sudhir , Bagga Rupali Verma
Published: December 2022

INTRODUCTION:

Childbirth is regarded as an important life event for women, and growing numbers of them are making the choice to give birth by cesarean delivery. Increasing rate of births by cesarean section is an issue of concern in many countries. In order to reduce the rates of unnecessary cesarean sections, it is essential to acquire information of the reasons that motivate physicians to carry out cesarean sections rather than vaginal deliveries. The objective of present study is to evaluate whether the education process for undergraduate medical students affects their decision-making.

MATERIALS AND METHODS:

The present study was cross-sectional and questionnaire based. A total of 292 students participated in the study. Out of which, 150 were first-year students and 142 were doing internship in Maharashtra Institute of Medical Education and Research (MIMER), Talegaon Dabhade, Maharashtra, India. The study was conducted in the months of June and July 2019. Data was collected with the help of person to person interview of all the participants who satisfied the inclusion criteria after obtaining their informed consent. The data was entered by using Microsoft Excel 2007 and was analyzed using Epi Info version 3.3.2. The data was tabulated and analyzed according to responses which were given by the respondents.

RESULTS:

A total of 292 students answered the questionnaire. Age of participants varied between 19 and 23 years. 130 males and 162 females were the subjects, out of which 40 students declared fear of labor. Most of the students preferred vaginal delivery over cesarean sections in all the four scenarios. The difference of opinion was significant in case of an uneventful pregnancy and normal pregnancy under their care. For general population as healthcare manager this difference of opinion was not significant. In case of one's own or partner's delivery, internship students preferred cesarean section but this difference was statistically non-significant.

CONCLUSION:

Most of the students would recommend vaginal delivery because this form of delivery has fewer risks as compared to cesarean section. Majority of students chose vaginal delivery for the birth of their own child; however, a higher number of interns as compared to first year students preferred cesarean section. Pain associated with vaginal delivery was the most common reason given for choosing cesarean section. The student's preference for childbirth changed in due course of graduation toward cesarean section. This indicates a probable effect of medical education on permissive culture of cesarean section as a mode of delivery.
Nonlinear modulational dynamics of spectrally stable Lugiato–Lefever periodic waves
Authors: Haragus Mariana , Johnson Mathew A. , Perkins Wesley R. , de Rijk Björn
Published: December 2022

We consider the nonlinear stability of spectrally stable periodic waves in the Lugiato–
Lefever equation (LLE), a damped nonlinear Schrödinger equation with forcing that arises in nonlinear
optics. So far, nonlinear stability of such solutions has only been established against co-periodic
perturbations by exploiting the existence of a spectral gap. In this paper, we consider perturbations
which are localized, i.e., integrable on the line. Such localized perturbations naturally yield
the absence of a spectral gap, so we must rely on a substantially different method with origins in
the stability analysis of periodic waves in reaction–diffusion systems. The relevant linear estimates
have been obtained in recent work by the first three authors through a delicate decomposition of the
associated linearized solution operator. Since its most critical part just decays diffusively, the nonlinear
iteration can only be closed if one allows for a spatio-temporal phase modulation. However,
the modulated perturbation satisfies a quasilinear equation yielding an apparent loss of regularity.
To overcome this obstacle, we incorporate tame estimates on the unmodulated perturbation, which
satisfies a semilinear equation in which no derivatives are lost, yet where decay is too slow to close
an independent iteration scheme. We obtain nonlinear stability of periodic steady waves in the LLE
against localized perturbations with precisely the same decay rates as predicted by the linear theory.
