Background: Immunization aims to reduce morbidity, mortality, and disability due to vaccine-preventable diseases. Many children in Indo­nesia have not received any immunization, or their immunization status is incomplete. Efforts should be made to raise awareness of parents to participate in completing their child's immunization. This study aimed to analyze the behavioral factors that influence the complete­ness of immunization in infants Subjects and Method: A cross-sectional study conducted at 21 health centers in Karanganyar, Central Java, from January to March 2020. Subjects were 200 mothers with children aged 12-23 months that were selected using a fixed disease sampling technique. The dependent vari­able was the completeness of immunization. The independent variables at level 1 were edu­cation, knowledge, information and education, perceived benefits, perceived barriers, intentions, subjec­tive norms, and attitudes. The independent vari­ables at level 2 were the contextual health center. The data were collected by question­naire and analyzed using a multilevel analysis. Results: Complete immunization in infants probably occurred with high maternal education (OR = 24.02; 95% CI = 1.61 to 359.17; p = 0.021), information obtained (OR = 52.31; 95% CI = 1.35 to 2021.69; p = 0.034), good knowledge (OR = 49.20; 95% CI = 71.54 to 1574.62; p = 0.028), high perceived benefit (OR= 31.26; 95% CI= 1.28 to 762.77; p= 0.035), strong intention (OR= 17.84; 95% CI= 1.59 to 199.83; p= 0.019), sup­portive subjective norm (OR = 94.69; 95% CI = 1.91 to 4683.14; p = 0.022), positive attitude (OR= 68.71; 95% CI= 2.40 to 1967.08; p= 0.013). Completeness of immunization in infants decre­as­ed with big perceived barrier (OR= 0.02; 95% CI= 0.01 to 0.67; p= 0.028). Health center acc­re­ditation showed a contextual effect on the level of completeness of immunization with Intra-Class Correlation (ICC)= 20.42%. Conclusion: Immunization completeness in infants increases with high maternal education, good knowledge, high perceived benefits, strong intentions, supportive subjective norms, positive attitudes. Completeness of immunization decre­as­ed with a big perceived barrier. Health centers have a large contextual influence on the comple­teness of immunization in infants.

Published: February 2021

It has been debated that effective essential public services delivery is crucial to inculcate inclusive growth in cities over the past decades. Cities continue to be central to the debate; however, the current study focuses on industrial towns. As industrial towns' development around cities attract investment and promote economic growth, the present research studies the impact of essential public services delivery on promoting inclusive growth for inhabitants of industrial towns in developing countries. Human Capabilities Dimension Approach and its parameters (Social and Physical Infrastructure) have been employed to explore the role of basic amenities in transferring growth levels across all population sections. The idea explored is studied through Mandideep Industrial Town's case study, where six parameters (Physical and socioeconomic status, water supply, sanitation, health care facilities, education facilities), and perceived inclusive growth have been considered for data collection and analysis. Indicators under each parameter are analyzed based on the 4A's-Availability, Accessibility, Awareness, and Affordability. Site selection revolved around a city reconnaissance survey and Household survey for 200 households. Aggregated analysis for the city and ward-wise comparative analysis and statistical correlation tools were used to establish a relationship between basic public services delivery and perceived inclusive growth. The research aims to study and establish a correlation between public service delivery and perceived inclusive growth by the industrial town's inhabitants. Discussions following data analysis led to recommendations for city and ward-level. The importance of efficient service delivery for increased perception of inclusive growth is established. Along with the six parameters considered for the study, physical and environmental planning emerge as crucial parameters that impact other public services for enhanced inclusive growth in industrial cities. Doi: 10.28991/cej-2021-03091648 Full Text: PDF

Published: February 2021

This paper investigates the effect of nano-papyrus cane ash as an additive on concretes’ mechanical and physical properties. Three types of concrete mixtures, 1:2:4, 1:1.5:3, and 1:1:2 were prepared for each mixture, nano-papyrus ash was added in five different dosages of 0.75, 1.5, 3, 4.5, and 6% by weight of cement; therefore, eighteen mixes would be studied in this work. Physical properties represented by dry density and slump were also measured for each mix. Moreover, to evaluate the mechanical properties development split tensile strength and compressive strength were obtained at age (7 and 28). Results manifested that the adding of nano ash developed the compressive strength and split tensile strength of concrete and the maximum enhancement recognized in the mixes with a content of 4.5% nano-papyrus in each studied mixture in this work. The slump test results indicated that the workability of concrete increased with adding nano-papyrus ash gradually with increasing nanoparticles' content. As well as, dry density was significant increased with nano-papyrus ratio; greater values were recorded in mixtures with 1.5-4.5% content of nano-papyrus. When comparing the concrete mixes used, it was found that the best results were obtained with 1:1:2 mixtures. This remarkable improvement in concrete properties considers the nano-papyrus is considered a cement economical and useful replacement for traditional construction material. Doi: 10.28991/cej-2021-03091649 Full Text: PDF
Exegeting Sūra al Fātiḥa for the Masses: Bediüzzaman Said Nursi and Haji Muḥammad Saʿīd bin ʿUmar
Authors: Riddell Peter G
Published: February 2021

Purpose: This article considers exegetical perspectives on the best known Sūra of the Qur’ān from two exegetes who lived in diverse contexts in the late nineteenth- and early twentieth-century Caliphate. Bediüzzaman Said Nursi is arguably the most influential theologian to emerge from in Ottoman Turkey in its long history. Haji Muḥammad Saʿīd bin ʿUmar, by contrast, enjoys a local reputation as a scholar in the Malay-Indonesian region but is unknown outside of that area. Methodology: This research is based on a comparative analysis of the exegesis of both scholars on Sūra al-Fātiḥa, exploring the techniques they used to reach ordinary Muslims with their exegesis, not just highly educated Muslims. Findings: Said Nursi and Muḥammad Saʿīd bin ʿUmar came from quite different backgrounds and contexts. Moreover, their exegetical styles were fundamentally different, with the former’s being more thematic and the latter’s being more literalist. Nevertheless, each succeeded in producing exegesis that reached the masses, thereby meeting their overall goals of reinforcing the commitment to faith and dynamic spirit of Muslims in their respective contexts. Originality: This research is original in various ways. First, comparative studies of Said Nursi and Malay-language exegetes are few in number. Second, the identification of similarities in the results of studies on exegesis despite the use of different methods requires greater scholarly attention. This article should stimulate interest in further studies on the matter.

Authors: Myneni Kranti kumar , D Rajan
Published: February 2021

In recent times due to the Indian economic growth, there is a surge in construction activities. This surge has led to an excess amount of demolition waste that is produced. According to the Building Material Promotion Council, India generates an estimated 150 million tons of C and D waste every year. Some existing initiatives and the significant stakeholders' involvement have created the demolition waste management systems essential in the building’s demolition phase. The research in the C and D and Awareness program for C and D waste that initiated has led to the implementation of some waste management systems in the building's demolition phase. In India, the amount of demolition waste produced is higher than the construction waste produced while constructing buildings. So, it is essential for the demolition waste mitigation plan in the building's demolition phase. The study aims to know circular construction and current demolition waste management performance in the Indian construction industry. Through literature review, demolition waste management systems that are carried out all around the world are collected. The current practices carried out by diﬀerent stakeholders practicing in India are known through a questionnaire survey. Data interpretation is made using the data collected in the literature review and the questionnaire survey. This research identified the signiﬁcant beneﬁts, barriers, and motivation factors to implement the waste management system, and proposing any necessary changes. Designer innovation and BIM deconstruction is considered as one of the barrier-breaking innovation in adopting the circular construction.

Published: February 2021

The Human three-dimensional (3D) musculoskeletal model is based on motion analysis methods and can be obtained by particular motion capture systems that export 3D data with coordinate 3D (C3D) format. Unique cameras and specific software are essential for analyzing the data. This equipment is quite expensive, and using them is time-consuming. This research intends to use ordinary video cameras and open source systems to get 3D data and create a C3D format due to these problems. By capturing movements with two video cameras, marker coordination is obtainable using Skill-Spector. To create C3D data from 3D coordinates of the body points, MATLAB functions were used. The subject was captured simultaneously with both the Cortex system and two video cameras during each validation test. The mean correlation coefficient of datasets is 0.7. This method can be used as an alternative method for motion analysis due to a more detailed comparison. The C3D data collection, which we presented in this research, is more accessible and cost-efficient than other systems. In this method, only two cameras have been used.
PET/MRI, aiming to improve the target for Fractionated Stereotactic Radiotherapy (FSRT) in recurrence of resected skull base meningioma after 2 years: Case report
Authors: Sebastião Corrêa
Published: February 2021

The increasing use of highly conformal radiation deliberates a higher accurate targeting. Contouring and clinical judgment are presumably the crucial point, thus positron emission tomography/magnetic resonance imaging PET/MRI with somatostatin analogs appears to be useful in radiotherapy target definition. A case report of a 43-year-old woman presented with a recurrence of a meningioma (World Health Organization group I classification) in skull base, 2 years after resection. Magnetic resonance imaging (MRI) revealed a left sided skull base mass on sphenoid wing, anterior clinoid and with a soft tissue component in the lateral portion of the orbit. Contrast-enhanced MRI and a computed tomography (CT) dedicated were used to the radiotherapy planning. Aiming an improvement on target volume delineation, 68Ga-DOTATOC-PET/MRI was also performed due the difficult localization of the tumor in skull base. Was treated using intensity-modulated radiotherapy (IMRT) to a total dose of 54 Gy in 28 fractions. It was prescribed to the planning target volume (PTV), defined based of both imaging modalities. In our case PET/MRI helped to define the target, which volume becomes bigger than that based exclusively on MRI and CT.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe multiorgan hypersensitivity reaction mostly caused by several eliciting drugs in patients with a genetic predisposition. Incidence of DRESS in children is very variable, frome 1:1000 to 1:10.000, and the mortality rate seems to be lower than 10%. Anti-convulsants are the main drugs involved both in adults and in children. The treatment of choice is the prompt withdrawn of the offending drug and using intravenous immunoglobulins and corticosteroids used in synergy. In recent years, emerging studies have outlined the disease more clearly. We present a pediatric case in which the patient developed DRESS syndrome as a result of exposure to lamotrigine before and carbamazepine after and a relapse after exposure to omeprazole. Starting from this case report we provide an overview on DRESS Syndrome.

Published: February 2021

Background: Interleukin-6 (IL-6) promotes antibody production. The objective of this study was to investigate whether IL-6 C-572G single nucleotide polymorphisms (SNP) and clinical factors are associated with positive platelet antibody test. Materials and methods: Thirty platelet recipients with platelet antibodies (responders) and 20 platelet recipients without platelet antibodies (non-responders) were randomly selected. The -572 C>G (rs 1800796) SNPs in the promoter region of IL-6 gene were genotyped by polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. Solid phase red cell adherence assay (SPRCA) was used for platelet antibody detection. Results: Age, sex, percentage patients with benign diseases, and percentage of patients with homozygotes for the C allele at position -572 of the IL-6 gene were similar between responders and non-responders. Although the amounts of platelets pheresis transfused to patients with hematologic diseases were higher than those of non-hematologic diseases (47.2 ± 54.2 vs. 17.4 ± 13.8 units, p = 0.019), detection rate of platelet antibodies was lower in patients with hematologic diseases than that in patients with non-hematologic diseases (42.3% vs. 79.2%, p = 0.01). Conclusion: There was no association between IL-6 C-572G gene polymorphism and positive reactivity in solid phase platelet antibody detection method in platelet recipients.

Formation of anode spots on rotating graphite crucible in the plasma arc furnace was investigated. The size and temperatures of the spots were determined by means of photographs and optical pyrometer. Composition of the plasma in anode spot region has been calculated. Cylindrical crucible of 100 mm in diameter with an axial hole of 40 mm in diameter and 28 mm in depth was rotated with the speed of ~100 rpm. Cylindrical cathode of 50 mm in diameter had an axial channel of 24 mm in diameter. Argon was fed through the channel as plasma forming gas. Crucible and cathode were located in the steel water cooled chamber with a volume of 150 liters. The arc was several centimeters long, arc current was 560-630 A. It was shown experimentally that 23-25 kW argon plasma arc can forms contracted or diffuse anode spot. The current density of contracted spot is 1800  A/cm2, while that of diffuse spot is ~250 A/cm2. Contracted spot formation occurs on a cold crucible and accompanied by intensive evaporation of graphite in a spot region. The carbon vapor decreased ionization potential of plasma near the anode and promoted contraction. A uniform heating of the hole in crucible up to 2700 K is needed for transformation of the contracted spot into diffuse one. Such heating was attained by rotation of crucible. Thermal isolation of crucible also promotes diffuse spot formation. Poisson’s equation was solved, and the voltage falls in space charge zones were calculated for contracted and diffuse spots as 10.7 and 1.5 V respectively. It was assumed that the lesser voltage fall promotes the diffuse spot formation.

Published: February 2021

The possibility of obtaining a superhard plasma coating based on titanium, nitrogen and carbon on a metal substrate in a nitrogen atmosphere is shown. The coatings were deposited in one short-term accelerator operation cycle under the action of a hyperspeed jet of electroerosive Ti-containing plasma on the substrate surface. It has been shown by SEM and XRD that nanostructured layers of titanium nitride and titanium carbonitride are formed, providing a high hardness of the coating. Plasma coatings deposited in a nitrogen atmosphere have a higher hardness (19.6 GPa) than coatings deposited in air (16.2 GPa), which is due to a higher content of nitride crystalline phases in the coating material. XRD data showed that the coherent-scattering region of crystalline phases in coatings deposited in an atmosphere of air and in a nitrogen atmosphere is ~10-40 nm, which confirms the nanostructuring of all crystalline phases presented in the coating.

Spark plasma sintering (SPS) of plasma-chemical nanopowders tungsten carbide with a high oxygen content are studied. The results show that the nanopowder WC shrinkages during SPS is limited by grain boundary diffusion with abnormally low activation energies. It is established that the decrease in the activation energy can be caused by the influence of oxygen on the diffusion permeability of the tungsten carbide grain boundaries at the stage of intense compaction, as well as by abnormal grain growth at the stage of high-temperature sintering. The SPS kinetics of WC-W2C-WO3-W nanopowder compositions at the stage of intense compaction is controlled by the rate of oxide particle sintering with their simultaneous transformation into W2C particles, and then, by the plastic flow of W2C particles in the presence of W particles at the stage of high-temperature sintering. Using the SPS method, we obtained ceramics with a high density (98-99%), ultrafine-grained structure (the average grain size is less than 0.3 mm), having an increased hardness HV = 30.5 GPa with a Palmquist crack resistance of ~6.5 MPa·m1/2.

Effects of the low-temperature plasma exposure, γ-irradiation, and joint g-irradiation and plasma exposure on the structure and surface properties of thin films based on polylactic acid (PLA) have been investigated. Films were obtained by the method a solvent-casting. It has been shown that films based on polylactic acid have topographically different sides: a smoother inner side and embossed outer one. PLA films have properties close to those hydrophobic, with a contact angle in the range of 70°-73° regardless of the surface side and belong to a weakly polar materials. The combined effect of plasma and gamma radiation slightly changes the surface topography. The effect of low-temperature plasma on the surface of the films leads to a decrease in the contact angle by 13°-55° (9-11%) and an increase in surface energy due to the polar component. The results of in vivo experiments on rabbits are presented. Biomicroscopy, optical coherence tomography, morphological and electron microscopic examination of the cornea after implantation of initial and radiation and plasma treated films showed that implantation of the films in the anterior chamber is not accompanied by a pronounced inflammatory reaction and increased intraocular pressure, while maintaining the morphological structure of the cornea almost unchanged.

The mechanoluminescence of the composite materials based on polymethyl-methacrylate and fine-dispersed powders of Sr4Al14O25:(Eu2+,Dy3+) phosphor with a centrosymmetric crystal structure of microcrystals and SrAl2O4:(Eu2+, Dy3+) phosphor with noncentrosymmetric crystalline structure were investigated. To study of mechanoluminescence, the composite layer with a thickness of ~250-300 μm was deposited on the surface of polymethyl-methacrylate substrate transparent in the visible spectral region. The mechanoluminescence of the composite layer was excited by the action of a mechanical striker, short laser pulses in air and water, and dynamic pressure of the stylus sliding over the surface of the mechanoluminescent layer. It is shown that the composite material based on a polymer and SrAl2O4:(Eu2+,Dy3+) powder with a noncentrosymmetric crystal lattice has a pronounced mechanoluminescence, while the composite material with Sr4Al14O25:(Eu2+,Dy3+) powder does not exhibit of the mechanoluminescent properties. It was shown that the excitation of mechanoluminescence in water begins at a much lower power density of the laser pulses than in air. The produced composite layer is shown to exhibit a high efficiency of “mechanooptical” transformation and can be used for recording and visualizing mechanical effects in mechatronic systems.
Can we predict and take a proper treatment for postpartum pulmonary embolism? A single institution review of five cases
Authors: Chung Soo-Ho , Choi Chang Woo , Sang Jae Hong
Published: February 2021

Postpartum pulmonary embolism (PPE) is a rare disorder in the puerperium that can present a wide range of symptoms after childbirth. This condition can lead to death and is the most common cause of maternal mortality, accounting for about 10% of all maternal deaths in the United States. A previous study conducted over 3 years (2014-2016) followed five patients diagnosed with postpartum pulmonary embolism, two of whom died. As PPE is characterized by a variety of symptoms, patients suspected of this condition require prompt diagnosis and treatment. Based on the previous investigation of five patients, the present study aimed to elucidate considerations for early treatment and diagnosis. Maternal mortality can be minimized by proper treatment and early detection using contrast-enhanced chest computerized tomography and echocardiography in women during or after delivery, particularly those with suspected embolism.

Introduction: Sepsis or septic shock, a life-threatening condition, is rarely reported as the initial manifestation of uterine malignancy. Case report: A 43-year-old woman consulted our hospital for pyrexia, anorexia, dyspnea, and a markedly distended abdomen. Computed tomography images showed a large abdominal tumor occupying almost the entire abdominal cavity with an air-fluid level and multiple masses in both lungs. Pelvic examination revealed necrotic tissues with blood, prolapsing from the uterus, and having a putrid odor. Her vital signs indicated a systemic inflammatory response syndrome. Antibiotic, anti-shock, and anti-disseminated intravascular coagulation therapies were administrated, but the patient died of multiple organ failure at 22 hours after admission. Autopsy and histopathological examination revealed that the giant abdominal mass was a uterine leiomyosarcoma, in which the myometrium was extensively necrotic with a putrid odor. The patient’s blood culture was positive for Escherichia coli, and sepsis and septic shock due to intrauterine infection of the uterine leiomyosarcoma was considered as the cause of death. Conclusions: Physicians should be aware that uterine malignancy could present as sepsis in women with an abdominal mass.

Objective: We purposed to investigate the difference between near-field and far-field of PI (pulsatility index) and peak systolic velocity (PSV) of the middle cerebral artery (MCA) that are important in the management of fetal growth restriction and fetal anemia. Methods: This prospective study was conducted with 130 single uncomplicated pregnancies. Doppler was applied to near-and far-field of proximal MCA while PSV and PI were recorded and compared between two sides as well as according to body mass index (BMI) and gestational weeks of participants. Results: There was no statistically significant difference between near and far-fields of MCA PI (P = 0.75). However, a statistically significant difference in PSV was observed (P = 0.03), and this was especially noticeable in women with normal BMI (P = 0.009). On the other hand, there was no difference between MCA PI or PSV in women with a BMI higher than 25. Also, no significant difference was observed between groups, which were subcategorized according to gestational weeks. Conclusions: Our data suggest that the far-field PSV values may be higher than near-field MCA PSV values; sonographers should bear in mind that while far and near-field PSV can differ, conversely MCA PI can safely be assessed from both the near and far-fields of MCA in case of technical difficulty.

This study aimed to compare perinatal outcomes, including nonreassuring fetal status, according to antenatal corticosteroid therapy (ACT) use during late-preterm and early-term pregnancies. This was a retrospective cohort study of women with singleton pregnancies who were at risk of late-preterm (34-36+6 weeks) birth or early-term (37-38+6 weeks) scheduled cesarean section from August 2017-July 2019. ACT was administered until June 2018, after which a policy was implemented such that ACT was not used for pregnant women in the above circumstances. Women were grouped based on whether they delivered before or after the policy change and were subdivided into late-preterm birth and early-term scheduled cesarean section groups to reduce variations in newborn outcomes. Multivariable logistic regression was used to determine whether the use of antenatal corticosteroids increased the odds of perinatal outcomes. In total, 216 women (215 neonates, 1 stillborn) were included. In the late-preterm delivery group, the rate of nonreassuring fetal status was significantly higher in the antenatal corticosteroid group than in the non-corticosteroid group (33.3% vs 12.0%, P = 0.017). In the early-term delivery group, the rate was non-significantly higher in the antenatal corticosteroid use group (19.0% vs 6.3%, P = 0.091). In the multivariable logistic regression, ACT was associated with an increased risk of nonreassuring fetal status (P = 0.025) and a reduced incidence of transient tachypnea of the newborn (TTN) (P = 0.011). We determined for the first time that ACT in late-preterm and early-term pregnancy is associated with nonreassuring fetal status. Here, ACT in late-preterm and early-term pregnancy had no benefit beyond decreasing the TTN rate.

Background: Previous studies had shown that major uterine wall resection and reconstruction of the uterus (MURU) was safe and effective in the treatment of adenomyosis. However, MURU results in loss of a significant amount of myometrial and some endometrial tissues, which may have an impact on uterine hemodynamics and ovarian function. Therefore, it is necessary to study the changes of uterine hemodynamics and ovarian function in patients after MURU, in order to provide an evidence-base for its clinical application. Objective: To explore the effects of major uterine wall resection and reconstruction of the uterus (MURU) on uterine hemodynamics and ovarian function in patients with adenomyosis. Study design: The maximum thickness of unilateral uterine muscle wall or the maximum diameters of adenomyosis focus were measured by ultrasonography. Patients with adenomyosis were divided into three groups: mild, moderate or severe. Fifty cases of adenomyosis without fertility requirement were treated with MURU (observation group), and levonorgestrel-releasing system (LNG-IUS) was placed in uterine cavity during the operation. Fifty patients with intramural myoma of the uterus were selected for hysteromyomectomy (control group). The changes of arterial pulsation index (PI) and resistance index (RI) of uterine artery, as well as antral follicle count (AFC) and serum antimullerian hormone (AMH) were observed before operation and 1 month, 3 months, 6 months, 12 months and 18 months post-operation. Results: No complications were observed in both groups, no significant difference in uterine hemodynamics and ovarian function were found between the two groups (P > 0.05). During intragroup comparison, there were no significant changes in PI and RI before and after operation in the two groups, and no significant changes in AFC and AMH were detected in both groups before and after operation (P > 0.05). Conclusions: MURU did not significantly affect the uterine hemodynamics and ovarian function in patients with adenomyosis, but the long-term effects need to be further investigated.

WARGA NEGARA MEMAHAMI DAN MELAKSANAKAN PANCASILA SEBAGAI IDEOLOGI NEGARA
Authors: Fahrizal Rozi
Published: February 2021

Pancasila adalah ideologi terbuka. Ungkapan yang sederhana tapi syarat makna ini sekarang berkembang dan mulai membudaya dalam masyarakat kita. Memang suatu konsep yang abstrak seperti “Pancasila adalah ideologi terbuka” memerlukan waktu untuk memantapkan proses pemahaman, penghayatan, pembudayaan dan pengamalannya dalam masyarakat. Kehadiran proses itu menunjukkan bahwa roh atau jiwa dari konsep itu hidup dan berkembang. Roh itu tumbuh secara incremental, berangsur-angsur, dalam pemikiran dan praktek dalam kehidupan masyarakat sehari-hari. Ia berkembang bagaikan tanaman yang tumbuh menjadi pohon yang rindang. Agar proses pertumbuhannya wajar, sehat dan segar ia memerlukan pupuk melalui pengembangan pemikiran-pemikiran baru yang relevan dan perlu pula disirami dan disiami dengan praktek-praktek yang konkrit dalam kehidupan sehari-hari. Melalui itu semua menjadilah ia suatu konsep yang hidup dan dinamis. Kehadirannya terasa riil, komunikatif dan menjamah dalam berbagai bidang kehidupan dari satu generasi ke generasi berikutnya.Demikianlah menurut pandangan kita, suatu ideologi terbuka mengandung semacam dinamika internal yang memungkinkannya untuk memperbaharui diri atau maknanya dari waktu ke waktu sehingga isinya tetap relevan dan komunikatif sepanjang zaman, tanpa menyimpang dari apalagi mengingkari hakekat atau jati dirinya. Pembaharuan diri (self-renewal) atau pengembangan maknanya itu bukan berarti merevisi apalagi mengganti nilai-nilai dasar yang terkandung di dalamnya. Bilamana nilai-nilai dasar itu direvisi apalagi diganti, maka ideologitersebut sudah kehilangan hakekat atau jati dirinya, dan oleh karena itu meskipun secara formal ia mungkin masih ada, secara substansi ia tidak lagi hadir karena sudah direvisi atau diganti oleh nilai-nilai dasar baru.

Speaking for the Arabian Subaltern; Latent Orientalism in Eldon Rutter’s Journey to Mecca
Authors: Abdellah Antar
Published: February 2021

The study reviews Eldon Rutter’s book “the two cities of Arabia” and makes a textual analysis of selected excerpts. Rutter’s book has long been praised for its objective tone in dealing with Islam and reporting on the religious rituals he witnessed and participated in while he was visiting Mecca in disguise as a Muslim pilgrim in the early 20th century. This study argues that while Rutter’s account does not seem to be biased against the Arabs and Muslims, there are certain instances of latent orientalism throughout his account. Said’s Orientalism and Spivak’s Subaltern are the main theoretical concepts against which the analysis and discussion are carried out. The study then compares between Rutter’s orientalism and present-day orientalism in dealing with the image of Arabs and Muslims in the media.
Amateur Hour: Improving Knowledge Diversity in Psychological and Behavioral Science by Harnessing Contributions from Amateurs
Authors: Mohlhenrich Erik , Krpan Dario
Published: February 2021

Contemporary psychological and behavioral science suffers from a lack of diversity regarding the key intellectual activities that constitute it, including its theorizing, empirical approaches, and topics studied. We refer to this type of diversity as knowledge diversity. To fix the knowledge diversity problem, scientists have proposed several solutions that would require transforming the field itself—an endeavor that can realistically be realized only in the long term. In this article, we propose that knowledge diversity could also be attained in the short term without transforming the field itself—by harnessing contributions from amateurs who can explore diverse aspects of psychology that are neglected in academia. We identify six such “blind spot” areas within which amateurs could contribute and discuss how this could be practically achieved. We hope that our article will inspire professionals and academic institutions to be more open toward amateur contributions to create a diverse body of knowledge.
