Fostering computational thinking through educational robotics: a model for creative computational problem solving
Authors: Chevalier Morgane , Giang Christian , Piatti Alberto , Mondada Francesco
Published: August 2020

Background

Educational robotics (ER) is increasingly used in classrooms to implement activities aimed at fostering the development of students’ computational thinking (CT) skills. Though previous works have proposed different models and frameworks to describe the underlying concepts of CT, very few have discussed how ER activities should be implemented in classrooms to effectively foster CT skill development. Particularly, there is a lack of operational frameworks, supporting teachers in the design, implementation, and assessment of ER activities aimed at CT skill development. The current study therefore presents a model that allows teachers to identify relevant CT concepts for different phases of ER activities and aims at helping them to appropriately plan instructional interventions. As an experimental validation, the proposed model was used to design and analyze an ER activity aimed at overcoming a problem that is often observed in classrooms: the trial-and-error loop, i.e., an over-investment in programming with respect to other tasks related to problem-solving.

Results

Two groups of primary school students participated in an ER activity using the educational robot Thymio. While one group completed the task without any imposed constraints, the other was subjected to an instructional intervention developed based on the proposed model. The results suggest that (i) a non-instructional approach for educational robotics activities (i.e., unlimited access to the programming interface) promotes a trial-and-error behavior; (ii) a scheduled blocking of the programming interface fosters cognitive processes related to problem understanding, idea generation, and solution formulation; (iii) progressively adjusting the blocking of the programming interface can help students in building a well-settled strategy to approach educational robotics problems and may represent an effective way to provide scaffolding.

Conclusions

The findings of this study provide initial evidence on the need for specific instructional interventions on ER activities, illustrating how teachers could use the proposed model to design ER activities aimed at CT skill development. However, future work should investigate whether teachers can effectively take advantage of the model for their teaching activities. Moreover, other intervention hypotheses have to be explored and tested in order to demonstrate a broader validity of the model.

Authors: Sakuma Shigeru , Ferri Mauro , Imai Hideki , Fortich Mesa Natalia , Blanco Victorio Daniel José , Apaza Alccayhuaman Karol Alí , Botticelli Daniele
Published: August 2020

Background

After sinus floor augmentation, a thickening of the sinus mucosa has been described. The aim of the present study was to evaluate the involvement of the maxillary sinus ostium in the edematous processes after a sinus floor augmentation procedure.

Methods

Seventy-two cone-beam computerized tomographies (CBSTs) were taken before sinus floor augmentation and after 1 week and 9 months from surgery and analyses. Sinus mucosa thickness and area, ostium diameter and patency, and extension of the post-surgical transient mucosal thickening in relation to the ostium were evaluated on the CBCTs for all three periods. The term “virtual” when referring to sinus mucosa thickness and area was introduced because of the edema and bleeding that both contributed to a transient thickening and additional elevation of the sinus mucosa.

Results

The mean virtual thickness of the sinus mucosa was 2.7 ± 4.0 mm, 7.7 ± 7.1 mm, 1.7 ± 2.0 mm before surgery, and after 1 week and 9 months. The virtual mucosa area was 37.2 ± 52.5 mm2, 184.5 ± 153.8 mm2, and 34.0 ± 50.7 mm2. The ostium diameter at the three periods evaluated was 1.8 ± 0.5 mm, 1.1 ± 0.6 mm, 1.5 ± 0.8 mm, respectively. Three infundibula (4.2%) were found out of patency before surgery while this number increased to 14 (19.4%) after 1 week. Nine months after surgery, only one infundibulum (1.4%) was out of patency, however, without presenting signs of sinus pathologies. The extension of the mucosal edema on the palatal sinus was reduced after 9 months of healing.

Conclusions

One week after sinus floor augmentation, the maxillary sinus mucosa increased in dimensions and in several cases involved the ostium, reducing its diameter and producing a transient loss of patency. After 9 months of healing, the initial conditions were recovered.

Authors: Shiratori Fumiaki , Hoshino Isamu , Gunji Hisashi , Takiguchi Nobuhiro , Nabeya Yoshihiro , Shimada Hideaki
Published: August 2020

Background

Although the first-line therapy for early-stage gastric mucosa-associated lymphoid tissue lymphoma is the eradication of Helicobacter pylori, the effect of eradication in Helicobacter pylori-negative cases is unclear. In this case report, we describe a surgical option for a case of Barrett’s esophageal cancer with concurrent gastric mucosa-associated lymphoid tissue lymphoma.

Case presentation

A 79-year-old man was admitted to our hospital with Barrett’s esophageal cancer and gastric mucosa-associated lymphoid tissue lymphoma. Initially, we performed endoscopic submucosal dissection for Barrett’s esophageal cancer. Since residual tumor was observed after the endoscopic submucosal dissection, we performed an esophagectomy with two-field lymph node dissection, which was followed by placement of a gastric conduit via the posterior mediastinal route. He was discharged 14 days after surgery. Although no additional treatment exists for mucosa-associated lymphoid tissue lymphoma, no recurrent disease has been detected to date.

Conclusion

An option to use a portion of the stomach with low-grade malignant mucosa-associated lymphoid tissue lymphoma as a conduit after esophagectomy was suggested.
Association between serum bilirubin and migraine in children and adolescents
Authors: Elshony Hosna S. , El Sheikh Wafik M. , Melake Mostafa S.
Published: August 2020

Background

Migraine in children and adolescents is very common and can be associated with equivalents, psychiatric disorders, or abnormal electroencephalogram findings. Neurogenic inflammation is involved in migraine pathogenesis where pro-inflammatory cytokines play a significant role. Recent studies have demonstrated that serum bilirubin can be considered as an antioxidant and cytoprotective agent and that its concentration may be influenced in migraine by neurogenic inflammation. Various studies have observed reduced serum bilirubin in migrainous adults, and few studies investigated the association between serum bilirubin and migraine in children and adolescents.

Objectives

To study the association between serum bilirubin and migraine in children and adolescents.

Patients and method

Serum samples were collected from 40 migrainous children and adolescents and from 40 controls. Total, direct, and indirect bilirubin concentrations were measured. Headache features, migraine equivalents, psychiatric comorbidity, and electroencephalogram findings were documented in migraineurs.

Results

Serum total, direct, and indirect bilirubin concentrations were significantly lower in migraineurs than controls. This was statistically significant associated with abnormal electroencephalogram findings during headache-free periods and not statistically significant associated with any headache feature, abnormal electroencephalogram findings during headache attacks, or psychiatric comorbidity.

Conclusion

Serum bilirubin concentration is lower in migrainous children and adolescents compared to control, with no association with specific migraine type or features, and thus may be considered a useful marker for neurogenic inflammation in migraine.
Prognostic value of CIP2A gene expression in adult Egyptian acute myeloid leukemia patients
Authors: Shafik Roxan E. , Ibrahim Azza M. , Said Fadwa , Hassan Naglaa M. , Shafik Hanan E. , Shokralla Hala A.
Published: August 2020

Background

Protein phosphatase 2A (PP2A) functions as a tumor suppressor in many cancers. Cancerous inhibitor of protein phosphatase 2A (CIP2A) inhibits PP2A proteolytic degradation of c-Myc and enhances cell growth and tumor formation in several tissues. CIP2A expression in acute myeloid leukemia (AML) and its effect on outcome of treatment were not reported in Egyptian patients.

Results

No significant difference was detected in CIP2A expression between AML and control groups (P = 0.48). However, in AML patients, those with low CIP2A expression had a longer median overall survival than those with high expression (P = 0.059). CIP2A expression was not related to the clinical and laboratory variables and did not affect response to treatment.

Conclusion

High-CIP2A expression was associated with a trend of shorter overall survival in adult Egyptian AML patients. It might serve as a useful marker to predict poor prognosis. CIP2A may represent a potential target for cancer therapy.
The Tragicomic Philosophy of Waiting for Godot
Authors: Turley Elliott
Published: August 2020

Samuel Beckett’s interest in tragicomedy has been clear since he attached the subtitle A Tragicomedy in Two Acts to the English translation of Waiting for Godot. This article articulates what exactly Beckettian tragicomedy does. Godot, Beckett’s foremost tragicomedy, stages the interplay of his wide-ranging literary and philosophical influences. Drawing on figures such as Arthur Schopenhauer, Jean Racine, Henri Bergson, Arnold Geulincx, and Fritz Mauthner, the play bends toward tragedy but undercuts any sense of finality with its slow unrolling. More than a metaphysical statement, this temporal model of tragicomedy offers a Beckettian ethics insistent on both the resigned compassion of tragedy and comedy’s power to critique. In outlining Godot’s tragicomic philosophy, the essay charts Beckett’s deployment of the various figures who inspire his play but also shows how this tragicomic paradigm functions in the theater—and how it inspires future dramatists.
Central Counterparty Exposure in Stressed Markets
Authors: Huang Wenqian , Menkveld Albert J. , Yu Shihao
Published: August 2020

Time is valuable, particularly in stressed markets. Because central counterparties (CCPs) have become systemically important, we need to understand the dynamics of their exposure toward clearing members at high frequencies. We track such exposure and decompose it, yielding the following insights. The composition of CCP exposure is fundamentally different in the tails. At extreme levels or during rapid increases, there is elevated crowding. This is the result of clearing members all concentrating their positions on a single security or a particular portfolio, which is desirable if motivated by hedging but worrying if due to speculation.

Accuracy and precision limitations in measuring luminance modulation for pixelated displays
Authors: Masaoka Kenichiro
Published: August 2020

This study examines the constraints in measuring the contrast modulation or line-pair luminance modulation for pixelated displays. Simulation results show that measurement precision is affected by the offset between the display pixels and the detector array of the light measuring device (LMD). The contrast modulation is underestimated if the spatial imaging performance of the LMD is inadequate. A high pixel ratio, i.e., the number of pixels of the measurement device per display pixel interval, is required to increase the measurement accuracy. However, determining the minimum required pixel ratio is not straightforward, as the accuracy depends on the display device architecture as well.
Reflection-based lab-in-fiber sensor integrated in a surgical needle for biomedical applications

Published: August 2020

Recently, lab-in-fiber (LIF) sensors have offered a new paradigm in many different scenarios, such as optofluidics, due to their ability to integrate different multiphysics sensor elements in a small space. In this Letter, the design and manufacture of a multiparameter sensing device is proposed, through the combination of an in-fiber air microcavity and a plane-by-plane fiber Bragg grating (FBG). The reflection-based sensor, with a length of less than 300 µm, is located at the end of a single-mode fiber and integrated into a surgical needle for exploitation in biomedical applications. Here we present the first (to our knowledge) ultra-short LIF sensor reported under the “touch and measure” approach. In this first prototype, the detection of axial tensile strain (

Establishing the nonlinear coefficient for extremely lossy waveguides
Authors: Li Gordon Han Ying , Tuniz Alessandro , Martijn de Sterke C.
Published: August 2020

The nonlinear coefficient

γ

is central to the study of cubically nonlinear optical guided-wave structures. It is well understood for lossless waveguides, but less so for lossy systems. A number of methods for calculating

γ

in lossy systems have been proposed, each resulting in different expressions. Here we identify the most accurate and practical expression for

γ

. We do so by applying the different expressions

γ

to air–gold surface plasmon polariton modes in the interband region of gold and compare with a fully numerical iterative method. We thus resolve the outstanding issue of which expression for the nonlinear coefficient to use for lossy waveguides, enabling new insights into the nonlinear response of such systems.
Glycosaminoglycan–Protein Interactions: The First Draft of the Glycosaminoglycan Interactome
Authors: Vallet Sylvain D. , Clerc Olivier , Ricard-Blum Sylvie
Published: August 2020

The six mammalian glycosaminoglycans (GAGs), chondroitin sulfate, dermatan sulfate, heparin, heparan sulfate, hyaluronan, and keratan sulfate, are linear polysaccharides. Except for hyaluronan, they are sulfated to various extent, and covalently attached to proteins to form proteoglycans. GAGs interact with growth factors, morphogens, chemokines, extracellular matrix proteins and their bioactive fragments, receptors, lipoproteins, and pathogens. These interactions mediate their functions, from embryonic development to extracellular matrix assembly and regulation of cell signaling in various physiological and pathological contexts such as angiogenesis, cancer, neurodegenerative diseases, and infections. We give an overview of GAG–protein interactions (i.e., specificity and chemical features of GAG- and protein-binding sequences), and review the available GAG–protein interaction networks. We also provide the first comprehensive draft of the GAG interactome composed of 832 biomolecules (827 proteins and five GAGs) and 932 protein–GAG interactions. This network is a scaffold, which in the future should integrate structures of GAG–protein complexes, quantitative data of the abundance of GAGs in tissues to build tissue-specific interactomes, and GAG interactions with metal ions such as calcium, which plays a major role in the assembly of the extracellular matrix and its interactions with cells. This contextualized interactome will be useful to identify druggable GAG–protein interactions for therapeutic purpose:
Gastric Cancer Among American Indian and Alaska Native Populations in the United States, 2005–2016
Authors: Melkonian Stephanie C. , Pete Dornell , Jim Melissa A. , Haverkamp Donald , Wiggins Charles L. , Bruce Michael G. , White Mary C.
Published: August 2020

INTRODUCTION:

American Indian and Alaska Native (AI/AN) populations have higher gastric cancer rates than the general US population. This study provides a comprehensive overview of incidence rates among AI/AN persons during 2005–2016 compared with non-Hispanic whites (whites).

METHODS:

Population-based cancer registry data for 2005–2016 were linked with the Indian Health Service patient registration databases to address racial misclassification. Age-adjusted gastric cancer incidence rates were expressed per 100,000 per year. Incidence and trend analyses were restricted to purchased/referred care delivery area counties in 6 geographic regions, comparing gastric cancer incidence rates for AI/AN vs white populations in the United States.

RESULTS:

Gastric cancer rates were higher in the AI/AN compared with white populations in nearly every US region. Incidence rates for central/distal portions of the stomach were higher in AI/AN individuals compared with whites. Rates of later stage gastric cancer were higher in AI/AN populations overall and in every region except the Pacific Coast and East. Incidence rates decreased significantly over time in both populations. Declining rates in the AI/AN populations were driven by changes in the Pacific Coast and Northern Plains regions.

DISCUSSION:

AI/AN populations have a disproportionately high incidence of gastric cancer, especially in Alaska. High incidence in the central/distal portions of the stomach among AI/AN populations likely reflects a high prevalence of Helicobacter pylori infection in these populations. These data can be used to develop interventions to reduce risk factors and improve access to health services among AI/AN people at high risk for gastric cancer.

Published: August 2020

INTRODUCTION:

The diagnosis of bile acid diarrhea is often missed because the availability of the 75seleno-taurohomocholic acid (SeHCAT) test is limited. We aimed to compare the biomarkers 7α-hydroxy-4-cholesten-3-one (C4) and fibroblast growth factor 19 (FGF19) with the SeHCAT test.

METHODS:

Patients with chronic diarrhea without intestinal resection referred for SeHCAT were prospectively recruited for this diagnostic accuracy study. Blood was sampled at fasting and after a stimulation meal with chenodeoxycholic acid. SeHCAT retention ≤10% defined bile acid diarrhea and >10% defined miscellaneous diarrhea. Receiver operating characteristics (ROC) were analyzed with SeHCAT as the gold standard. www.clinicaltrials.gov (NCT03059537).

RESULTS:

Patients with bile acid diarrhea (n = 26) had mean C4 of 30 ng/mL (95% confidence interval: 19–46) vs 8 (7–11; P < 0.001) in the miscellaneous diarrhea group (n = 45). Area under the ROC curve (ROCAUC) for C4 was 0.83 (0.72–0.93). C4 < 15 ng/mL had 85% (74%–96%) negative predictive value; C4 > 48 ng/mL had 82% (59%–100%) positive predictive value. Twenty patients had C4 values 15–48 ng/mL, of whom 11/20 had SeHCAT ≤10%. Median fasting FGF19 was 72 pg/mL (interquartile range: 53–146) vs 119 (84–240) (P = 0.004); ROCAUC was 0.71 (0.58–0.83). Stimulated FGF19 responses did not differ (P = 0.54).

DISCUSSION:

We identified C4 thresholds with clinically useful predictive values for the diagnosis of and screening for bile acid diarrhea in patients with chronic watery diarrhea. Further validation of the cutoff values with the placebo-controlled effect of sequestrant therapy is warranted (see Visual Abstract, Supplementary Digital Content 2, http://links.lww.com/AJG/B603).
Mapping the Brain to Predict Antisocial Behaviour: New Frontiers in Neurocriminology,‘New’ Challenges for Criminal Justice
Authors: Coppola Federica
Published: August 2020

Neuroscientific research on the relationship between neurobiology and antisocial behaviour has grown exponentially over the last two decades. One of the most intriguing challenges that has started occupying the minds of scientists and legal scholars is the potential use of neuroscience-based methodology to predict future antisocial behaviour in forensic and justice contexts. While neuroprediction holds the promise of adding predictive value to existing risk assessment tools, its hypothetical use for forensic and justice purposes touches on some specific ethical and legal issues, in particular the threat it poses to offenders’ individual rights and civil liberties under the pretext of enhancing public safety. This article provides some arguments for overcoming these concerns. More importantly, it argues that neuroprediction should be viewed as an instrument to help criminal justice integrate current punitive policies and measures with socio-rehabilitative strategies, which could improve the treatment of offenders at risk without threatening their individual rights.

Um dos tipos de sistema de informação que possibilita a integração das atividades e processos do negócio é o Sistema Integrado de Gestão/Enterprise Resource Planning – ERP. O objetivo desta pesquisa é avaliar a aceitação do emprego de um sistema de informações por integrantes de quatro organizações. A questão de pesquisa é: quais elementos se destacam na aceitação de ERPs tendo em vista a perspectiva do modelo UTAUT de avaliação? A importância da pesquisa está na prevenção de riscos para os negócios com a implantação de tecnologias. O modelo UTAUT de avaliação é uma síntese de vários modelos teóricos e é amplamente utilizado devido à sua característica de avaliação da percepção dos usuários, os reais utilizadores dos sistemas. O modelo verifica quatro fatores determinantes e quatro condições moderadoras da aceitação e intenção de uso da Tecnologia da Informação. Esta pesquisa é descritiva e qualitativa e utiliza o método de estudo de caso múltiplo. As análises evidenciaram unanimidade referente à preocupação com a falta de confiança nos usuários que alimentam o sistema e por consequência nas informações geradas. Nas empresas em que ocorreu a implantação parcial do sistema, houve queda da produtividade. Em contrapartida, houve aumento de produtividade nas empresas com implantação total do sistema. Em empresas nas quais o sistema era de uso opcional, quem o fazia ganhava empatia por parte dos gestores. A maior parte dos usuários mostraram-se insatisfeitos com a usabilidade dos sistemas, pois não eram considerados adequados aos tipos empresariais em que eram utilizados.

Authors: Sol Pablo
Published: August 2020

Resumen: El beso no es un tema muy frecuente en la poesía amorosa de Quevedo, sobre todo si la comparamos con algunos de sus modelos italianos. Cuando aparece, se trata casi siempre de un beso aparente o imaginario, que solo tiene lugar en la mente del amante. Este artículo clasifica y comenta filológicamente los poemas en torno al beso en la Musa Erato, cuarta de El Parnaso español, que reúne la mayor parte de la poesía amorosa de Quevedo.

Published: August 2020

Several methodologies for the preparation of nanofibrous materials exist. Electrospinning is currently the most popular technique due to its versatility and simplicity. Nanofibrous materials prepared in such a way are widely studied in medicine and material engineering. Polyvinyl butyral (PVB) nanofibers were generated by a rod-shaped spinning-electrode. Nanofibers were modified by a magnetic fluid (MF) added into the PVB solution. These magnetic nanofibers can be considered as a material for magnetic hyperthermia applications, either as implants or for the surface heating. The samples with various magnetic particle concentrations were tested in the alternating magnetic field. An immediate increase in the temperature after the field application was observed. The nature of the temperature rise is interesting: a non-linear increase could be seen, which is in contrast to the rising temperature for pure magnetic fluids.

The controlled delivery of anticancer drugs is driven by their interaction with carrier molecules. By creating complicated micelle-like complexes, amphiphilic polymers provide an opportunity to load drugs of various kinds. In this work, the interaction of the comb-like PEG-containing polymer poly(VEP-co-GMA)-graft-PEG with the water-soluble antitumor antibiotic doxorubicin and new water-insoluble derivatives of thiozalidinone Les-3883 characterized by a high anticancer efficiency has been studied in aqueous solutions by means of the SAXS, DLS, TEM, and photoluminescence methods. The formation of polymer micelles and their complexes with drugs, as well as their structural changes, is observed. The obtained results give evidence that the mechanism of organization of supramolecular complexes depends on the drug solubility in water. A potential capability of poly(VEP-co-GMA)-graft-PEG to prolong the drug circulation lifetime is confirmed.

Published: August 2020

We report the preliminary results obtained for polymers incorporating the azobenzene side-group as an optically active molecule. The reversible change of the thin film absorption is observed when illuminating it with monochromatic linearly polarized light under the applied external DC field. The magnotude of a change depends on the angle between the light polarization and the DC electric field direction.
Modified Mean-Field Theory of One-Dimensional Spin Models with Anisotropy and Long-Range Dipolar Interactions
Authors: Camp P. J. , Ivanov A. O.
Published: August 2020

The effects of interactions and anisotropy on the magnetic properties of linear chains of superparamagnetic nanoparticles are studied theoretically by mapping the problem onto spin models. With zero anisotropy, the magnetic dipole moments are free to rotate, and the system resembles a classical ferromagnetic Heisenberg model with long-range dipolar interactions. With strong anisotropy, they are constrained to align with the chain, and the system resembles the classical ferromagnetic Ising model with long-range interactions. Using a modified mean-field theory, expressions for the magnetization curve and initial magnetic susceptibility are derived from the response of a single particle subject to an effective field arising from the applied field and the interactions with the other particles. Various approximations for the effective field are tested against results from Monte Carlo simulations. It is shown that, for physically relevant interaction strengths, reliable theoretical predictions for both the zero-anisotropy and strong-anisotropy cases can be derived in a simple closed form.

Published: August 2020

Fullerenes tend to form clusters in different solutions. In this work, a brief survey and some results in the field of investigations of the structure and kinetics of clusters growing in C60 solutions are presented. The general character of this phenomenon for fullerenes is emphasized, and the considerations of mechanisms responsible for the formation and growth of clusters are discussed. We distinguish different types of fullerene solvents by the aggregation mechanism. The kinetics of cluster growth measured via the dynamic light scattering is presented. The complicated structure of clusters in different solutions is briefly discussed.

Published: August 2020

It is known that ferrofluids typically respond to magnetic fields and can be manipulated by such external fields. The particle assembly in magnetic nanofluids can be induced even by a direct current (dc) electric field. An experimental study of magnetic colloidal particles and their changes induced by an external electric field in a ferrofluid based on 2 transformer oils with different concentrations of nanoparticles is presented. By small-angle neutron scattering (SANS), we show the influence of the electric field intensity and the concentration on magnetic nanoparticle aggregates.

Clima de convivencia escolar en Chile: un análisis desde el nuevo marco de medición de calidad educativa
Authors: Padilla Fuentes Geraldo Bladimir , Rodríguez-Garcés Carlos René
Published: August 2020

Los puntajes en pruebas estandarizadas y el rendimiento escolar se han tornado indicadores insuficientes para medir y evaluar calidad en procesos de enseñanza-aprendizaje. En este contexto, los Otros Indicadores de Calidad (OIC) definidos por el Ministerio de Educación en Chile buscan subsanar esta debilidad complementando la métrica tradicional con un conjunto de índices asociados al desarrollo personal y social del estudiantado. Objetivo: perfilar el comportamiento del Clima de convivencia escolar y sus dimensiones, constituido en uno de los OIC trascendentales para dar cuenta de las condiciones en que se suscita el aprendizaje. Método: utilizando cuestionarios de contexto aplicados a estudiantes, profesores/as, padres y madres se analizan percepciones sobre organización, seguridad y respeto del espacio educativo con modelamiento estadístico inferencial. Resultados: la percepción y evaluación que se hace de la situación de convivencia tanto escolar como áulica está determinada por el rol, posición y responsabilidad del agente evaluador, ello explicaría la perspectiva crítica del estudiantado, la neutralidad docente y la desvinculación parental con el clima relacional del acontecer educativo. En razón de su intrínseca naturaleza de cotidianidad y compartir forzado en un espacio físico reducido y de proximidad, el clima áulico es particularmente problemático. Conclusiones: la problematización de este OIC realza la necesidad de fortalecer el educar para vivir en comunidad, particularmente cuando las percepciones de los actores están fuertemente colonizadas por la deseabilidad social y naturalizadas por la cotidianidad de climas de convivencia deteriorada.
The Conceptions of Sharia and Citizenship in Indonesia and Malaysia
Authors: Ali Muhamad
Published: August 2020

Indonesia and Malaysia offer comparative perspectives concerning the relationship between loyalties to the Muslim umma, local ethnicity, and the modern nation-state, and how interpretations of the sharia and modern constitution, laws, politics, and policies intersect in multiple and changing ways. This article seeks to compare and contrast some of the contemporary discourses on sharia and citizenship as demonstrated by Indonesian and Malaysian scholars, politicians, and activists. Both Indonesian and Malaysian constitutions were born out of the modern notion of citizenship that recognizes religious diversity. On the one hand, the Constitution of Indonesia does not specify Islam as the state religion, but the government promotes official religions. On the other hand, the Constitution of Malaysia makes it explicit that Islam is the state religion while recognizing religious diversity. The Indonesian government does not conflate particular ethnicity with Islam, whereas Malaysia integrates Islam and Malay ethnicity amidst Malaysian religious and ethnic plurality. Both cases prevent us from categorizing each case as either an Islamic legal conservatism or a modern legal liberalism. These two cases resist the binary opposition between sharia conservatism deemed against citizenship and modern legal liberalism deemed against religious laws. There are ambiguities, contradictions, as well as compromises and integration between conflicting ideas and systems concerning Islam and citizenship.
New Grounded Feminist Approach to Islam in Indonesia: A Textual Analysis of Rahima and Fahmina’s Publications
Authors: Nurmila Nina
Published: August 2020

This article aims to offer a textual analysis of Rahima and Fahmina’s publications. Rahima and Fahmina are two Non-Government Organizations founded in 2000 by a young generation of Nahdlatul Ulama (NU), one of the largest moderate Muslim organizations in Indonesia. There are more similarities than differences between Rahima and Fahmina because the persons involved in the organizations are close friends and, in fact, the same persons even though both are based in two different cities. Since their foundation, both Rahima and Fahmina have published many books and magazines. This article argues that both Rahima dan Fahmina publications offer a new grounded feminist approach to Islam, which counterbalance the dominant male-biased normative approach to Islam in most Muslim societies. These publications are based on their feminist activism and community engagement with the grass-root level of many Nahdlatul Ulama pesantrens (Islamic boarding schools). The topics of their publication cover many current issues such as fiqh of women’s reproductive rights and empowerment, fiqh of the daily life of migrant workers, fiqh of anti-trafficking, prevention of child marriage, violent extremism and religious pluralism. As a result, the progressive nature of their publications negates the existing label of NU as the traditionalist organization.

Published: August 2020

The magnetic transport properties -- magnetoresistive (MR) effects of MnNi/Co/Ag(Cu)/\break Py pinned spin valve structures (SVs) prepared by rf sputtering method and annealed at \(T_{a} = 100\)°C - 500°C for 30 minutes in high vacuum (\(\sim 10^{ - 5}\) torr) are investigated. The received results show a change in the observed MR behaviors from a normal giant magnetoresistance effect to an inverse magnetoresistance effect after annealing at high temperatures, 300°C and 400°C, for these SVs. The origin and mechanism of the IMR behavior are analyzed and discussed. These results will suggest an ability to manufacture SV devices used the IMR effect for enhancing the application capacities for SV-sensor systems.
On a Standard Model Extension with Vector-like Fermions and Abelian Symmetry
Authors: Tran Hieu Minh , Dinh Sang Quang , Trieu Trang Quynh
Published: August 2020

We investigate an extension of the standard model with vector-like fermions and an extra Abelian gauge symmetry. The particle mass spectrum is calculated explicitly. The Lagrangian terms for all the gauge interactions of leptons and quarks in the model are derived. We observe that while there is no new mixing in the lepton sector, the quark mixing plays an important role in the magnitudes of gauge interactions for quarks, particularly the interactions with massive \(W\), \(Z\) and \(Z'\) bosons. We calculate the contributions of the new vector-like leptons and quarks to the Peskin-Takeuchi parameters as well as the \(\rho\) parameter of the electroweak precision tests, and show that the model is realistic.
