Integrated fuzzy logic and multicriteria decision model methods for selecting suitable sites for wastewater treatment plant: A case study in the center of Basrah, Iraq
Authors: Lefta Feras A. , Hamdan Ahmed N. A.
Published: January 2024

In environmental infrastructure projects, decision-making can be complex and challenging because of the inherent trade-offs between environmental, economic, and social considerations. During urban development, wastewater treatment plant (WWTP) site selection is one of the most critical parts of environmental infrastructure. Choosing suitable sites for constructing a WWTP is based on various variables and limits. In the modeling phase of this study, ten criteria were developed from three main criteria to evaluate sites suitable for WWTPs. These criteria were slope, soil type, and proximity from rivers, roads, agricultural lands, railways, oil fields, groundwater, outfall, and residential areas. These parameters and their respective weights were determined based on a literature review, expert knowledge, field observation, and geophysical investigation. The fuzzy analytical hierarchy process (AHP) method, which integrates AHP and fuzzy logic, was used as a multicriteria decision-making, and fuzzy membership functions were performed to determine the criteria weights used with geographical information systems to select all available sites for the WWTP for the center of the Basrah province. The study concludes that the old Hamdan WWTP was located in an unsuitable area. In light of the rapid population growth in Basrah center in recent years, it may be proposed that a new WWTP be built in a new location that meets environmental, economic, and social criteria. This study reveals that 138.52 km2(or 9.98% of the total land area) is appropriate for constructing the new WWTP.
Elm wood (Ulmus rubra) vacuum drying at 40 °C studied by time domain nuclear magnetic resonance (TD-NMR)
Authors: Tan Rui , Zhao Zhihong , Liu Wenjing , Wu Shuang , Zhang Minghui
Published: January 2024

The time domain nuclear magnetic resonance (TD-NMR) technique was employed to distinguish various water states, and the moisture migration during Elm wood (Ulmus rubra) heartwood vacuum drying was quantitatively analyzed. The transverse relaxation time (T2) was employed to establish the correlation between drying time and moisture migration. Additionally, the longitudinal relaxation time (T1) was utilized to identify two types of water states within the cell wall: OH bound water (B-water) and more freely bound water (C-water). Meanwhile, the changes in these two types of bound water during the drying were investigated. The results demonstrated an exponential decrease in the content of OH bound water and more freely bound water with drying time. OH bound water within the cell wall predominated, with only a small portion of more freely bound water experiencing migration loss when the moisture content (MC) dropped below 20 %. Furthermore, OH bound water exhibited higher migration rate compared to more freely bound water at 10–20 % MC, while the motion of OH bound water molecules became highly restricted and stronger binding to cell walls than more freely bound water at a MC level of below 10 %. These findings yield a theoretical foundation and empirical support for optimizing drying methods.
Collaborative autoethnography in applied linguistics: reflecting on research practice
Authors: Adamson John Lindsay , Muller Theron
Published: January 2024

This reflective paper explores collaborative autoethnography (CAE) as a research method by analyzing 15 of our CAE English language teaching and applied linguistics studies published from 2015 to the present. Focus is given to tying CAE to its ethnographic roots, including autoethnography and duoethnography. The implications of CAE representing a methodological expansion of ethnographic methods from researching and reporting on the other to researching and representing one’s own authentic experiences are explored. We discuss the “counter-narratives” that CAE spaces facilitate, where minoritized opinions and experiences can be safely shared and (re)affirmed, including how to facilitate transformative experiences in practice. Two implications for CAE practice are shared. The first concerns the need for CAE participants to be conscious of different levels of participation, particularly as life circumstances change, and to flexibly accommodate these. The second concerns how CAEs should represent a process that facilitates growth and transformation rather than a final, published product. We conclude by noting that while CAE may have shortcomings, it represents a promising avenue of exploration for practitioners interested in developing professional practices through reflection and discussion with research collaborators.
English and ‘personality development’: the hyper-individualization and de-politicization of social mobility in India
Authors: Highet Katy
Published: January 2024

In the last two decades, English learning in India has undergone noticeable and subtle transformations. Alongside the massive increase in coaching centres to cater for widespread demand, there has also emerged a tacit understanding that it is no longer enough to speak English to be socially mobile: students must also engage in a range of self-work, or ‘personality development’. In this article, I draw on ethnographic data from an NGO in Delhi that seeks to alleviate poverty through English and personality development training for disadvantaged youth. I show how discourses of personality development (re)produce and juxtapose particular understandings of the self that work to hyper-individualize and depoliticize the project of social mobility. Situating these discourses within the context of shifting political economic configurations in India, this paper demonstrates how these notions of ‘personality development’ both emerge from and obscure long-standing and newly-developing colonial, caste and class histories, and how they work to produce depoliticised subjectivities.
Becoming/being a care worker: personality in a language training for migrant job seekers in Flanders
Authors: Nyssen Sara
Published: January 2024

In this article I will describe how personality was mobilized during a Dutch language course that prepared job seekers for the care sector. I show how more than language competences, what was valued was who someone was as a person. While the emphasis on job seekers’ personality in the context of a language course that prepared for an education and subsequent job in the care sector, is, on the one hand, in line with the general attention for the worker as a person and more specifically for what is generally referred to as soft skills, I show that the understanding of personality in the course also differs from how soft skills is generally understood: personality was seen as a stable essence, where potential for improvement was deemed to be limited. This view on personality can be associated with the history of care work and the morality attached to it, for which selection of workers is deemed necessary. Moreover, as I have shown, while personality is thought of as an abstract term that can be applied to categorize individuals separately from the specific context or from cultural or political influences, the type of personality that was required for a care worker was coded as feminine and associated with certain types of people along racialized lines. As such, there is an unequal distribution among which people are deemed suitable for care work. By demonstrating the effects of this specific understanding of personality, I also argue that it is important for language scholars to pay attention to such notions themselves, rather than to focus merely on their communication.
The “pedagogy of personality”: becoming better people in the English language teaching and learning space
Authors: Sunyol Andrea , Browning Peter
Published: January 2024

This paper interrogates how English language teaching and learning spaces become a locus for a “pedagogy of personality”: spaces where ideal forms of personhood can be transmitted, taught and learned. We draw on ethnographic accounts of moments produced in a municipal English language teaching programme in Rionegro, Colombia, and in the English language class of an elite international school near Barcelona, in Catalonia. We explore discourses mobilised by teachers, students, and school administrators that glorify personality traits that should enable students to become “good community members”, “good citizens” and to reflect on the ways in which language learning spaces are imagined to have an effect on learners’ personalities. We claim that it is not necessarily the English competence acquired in these spaces, or the act of speaking English itself, which is imagined as automatically triggering the enactment of ‘better’ forms of personality. Rather, we believe that our ethnographic data point to the fact that language curricula provide the space to construct, spread and normalise moral values which are associated to idealised forms of subjectivity, and desired forms of being. The discourses circulated through landscapes and classroom interactions show how the mere act of being in an English language learning space is expected to raise students’ awareness of the moral duty to become better, more responsible individuals. We make a key contribution to critical sociolinguistic research by placing a focus on how “good personality” is informed by the pedagogic trajectories of each space, beyond neoliberal projects of self. Moralising catholic discourses, values and ideologies, and broader humanist educational discourses inform ideas about personality and personality development in these spaces. Thus, we call for a slower sociolinguistics, that takes pause before reaching for the explanatory power of neoliberalism and makes room for the complex, historically sedimented logics of our research sites.
Anxiety and enjoyment in oral presentations: a mixed-method study into Chinese EFL learners’ oral presentation performance
Authors: Ding Xixin , Chen Min , Xu Qi
Published: January 2024

Despite the prevalence of emotion-centered studies in foreign language classrooms, there are scant studies focusing on one specific task, the oral presentation task. This research utilized questionnaires to measure 25 Chinese Business-English major sophomores’ Foreign Language Classroom Anxiety (FLCA) and Foreign Language Enjoyment (FLE) in a group oral presentation task. It aimed to unveil the relationships between FLCA/FLE and oral presentation performance, and to dig out factors affecting FLCA and FLE in oral presentations through self-reflective journals. It was reported that most participants generally enjoyed delivering oral presentations rather than felt anxious. Participants exhibited better performance in the content of their presentations as opposed to the delivery manner. Unlike the limited influence of FLE on oral presentations, FLCA showed significant negative correlations with overall presentation performance, particularly in participants’ vocal delivery, enthusiasm, and eye contact. Qualitative data revealed that participants’ FLCA and FLE in oral presentations were predominantly influenced by personal and peer-related factors. Based on the major findings, pedagogical suggestions were put forward to enhance learners’ oral presentation skills and promote academic oracy in higher education.
Antioxidant therapy for hepatic diseases: a double-edged sword
Authors: Das Sayandeep K. , Nerune Savitri M. , Das Kusal K.
Published: January 2024

Liver diseases are complex conditions, significantly influenced by oxidative stress. This comprehensive review assesses the therapeutic role of antioxidants likel-ascorbic acid and α tocopherol, beta-carotene, various minerals, and plant-based ingredients in mitigating oxidative stress-induced liver diseases. The manuscript delves into the critical influence of genetic and epigenetic factors on disease susceptibility, progression, and response to antioxidant therapy. While animal studies suggest antioxidant efficacy in liver disease treatment, human trials remain inconclusive, and caution is advised due to its possible potential pro-oxidant effects. Moreover, the interactions of antioxidants with other drugs necessitate careful consideration in the management of polypharmacy in liver disease patients. The review underscores the need for further research to establish the clinical benefits of antioxidants with understanding of possible antioxidant toxicities to elucidate the intricate interplay of genetic, epigenetic, and environmental factors in liver diseases. The aim is to foster a better understanding of the knowledge on hepatic disease management with judicial antioxidant therapies.
Realization of ultrastrong coupling between LSPR and Fabry–Pérot mode via self-assembly of Au-NPs on p-NiO/Au film
Authors: Garcia Alexis Angelo R. , Mao Cheng-An , Cheng Wen-Hui (Sophia)
Published: January 2024

The realization of higher coupling strengths between coupled resonant modes enables exploration of compelling phenomena in diverse fields of physics and chemistry. In this study, we focus on the modal coupling between localized surface plasmon resonance (LSPR) of Au nanoparticles (Au-NPs) and Fabry–Pérot mode (p-NiO/Au film). The effects of nanoparticle size, projected surface coverage (PSC), interparticle distance (IPD), and arrangement to the coupling strength between the two modes are theoretically investigated using finite-difference time-domain (FDTD) method. Au-NPs/p-NiO/Au film (ANA) nanostructures with NPs size of 10 nm, 30 nm, and 50 nm are considered. Numerical calculations point to larger size and higher projected surface coverage (also smaller IPD) of NPs as pre-eminent factors in enhancing the strength of modal coupling. ANA nanostructure with NPs size of 30 nm (ANA-30) and 50 nm (ANA-50) are experimentally fabricated via a facile air–liquid interface self-assembly. The fabricated nanodevices exhibit immense Rabi splitting energies of 655 meV (ANA-30) and 770 meV (ANA-50), and thus fulfill the ultrastrong coupling condition with remarkable splitting energy to bare (plasmon) energy ratio of 0.35 (ANA-30) and 0.4 (ANA-50). The physical insights presented in this study, together with the simple and scalable fabrication process, establish a viable approach to realize stronger coupling between LSPR and Fabry–Pérot mode in metal NPs/dielectric/metal film systems. This will be vital to take advantage of the promising performance enhancements of plasmonic-based nanostructures under strongly coupled regimes in areas such as solar to fuel conversion, sensing, opto-electronics, and quantum applications.

Authors: Possolo Antonio , Hibbert David Brynn , Stohner Jürgen , Bodnar Olha , Meija Juris
Published: January 2024

This Brief Guide reintroduces readers to the main concepts and technical tools used for the evaluation and expression of measurement uncertainty, including both classical and Bayesian statistical methods. The general approach is the same that was adopted by the Guide to the Expression of Uncertainty in Measurement (GUM): quantities whose values are surrounded by uncertainty are modeled as random variables, which enables the application of a wide range of techniques from probability and statistics to the evaluation of measurement uncertainty. All the methods presented are illustrated with examples involving real measurement results from a wide range of fields of chemistry and related sciences, ranging from classical analytical chemistry as practiced at the beginning to the 20th century, to contemporary studies of isotopic compositions of the elements and clinical trials. The supplementary material offers profusely annotated computer codes that allow the readers to reproduce all the calculations underlying the results presented in the examples.
Bayesian LASSO for population stratification correction in rare haplotype association studies
Authors: Liu Zilu , Turkmen Asuman Seda , Lin Shili
Published: January 2024

Population stratification (PS) is one major source of confounding in both single nucleotide polymorphism (SNP) and haplotype association studies. To address PS, principal component regression (PCR) and linear mixed model (LMM) are the current standards for SNP associations, which are also commonly borrowed for haplotype studies. However, the underfitting and overfitting problems introduced by PCR and LMM, respectively, have yet to be addressed. Furthermore, there have been only a few theoretical approaches proposed to address PS specifically for haplotypes. In this paper, we propose a new method under the Bayesian LASSO framework, QBLstrat, to account for PS in identifying rare and common haplotypes associated with a continuous trait of interest. QBLstrat utilizes a large number of principal components (PCs) with appropriate priors to sufficiently correct for PS, while shrinking the estimates of unassociated haplotypes and PCs. We compare the performance of QBLstrat with the Bayesian counterparts of PCR and LMM and a current method, haplo.stats. Extensive simulation studies and real data analyses show that QBLstrat is superior in controlling false positives while maintaining competitive power for identifying true positives under PS.
Study on the scale inhibition performance of organic chelating agent aided by surfactants on CaCO3 at high salinity condition

Published: January 2024

The salt blockage layer formed in the wellbore during the development of high salinity oil and gas fields has a serious impact on the safety of oil and gas production of the oil and gas fields. CaCO3 is the main component of scale in high salinity oil and gas fields. Herein, focusing on CaCO3 as an example, the precipitation and scaling process as well as the change of crystalline form of CaCO3 under different temperature and salinity conditions were studied. The effects of two addition methods of organic chelating agent on the solubilization and dislodgement of CaCO3 under high salinity conditions were also explored. The optimal concentration of organic chelating agent is determined to be 1 % and 5 % for solubilization and dislodgement, respectively. It was found that the solubilization is achieved by inhibiting the stable and difficult to treat calcite crystal phase to generate more irregular and more dispersed aragonite CaCO3. Organic chelating agent contains a large number of carboxyl groups in its molecules, which can be adsorbed onto the surface of CaCO3 crystals through electrostatic adsorption. By chelating Ca2+ in stable and difficult to treat calcite CaCO3, the further ordered growth of the crystals is prevented, causing lattice distortion or large crystal rupture, thereby achieving dislodgement. This study will provide theoretical and technical support for the solubilization and dislodgement of salt blockage layer in wellbore at high salinity conditions.
Influence of Deck Butt Weld Seams on Fatigue Life of Steel Bridge Decks Pavement: Parameter Optimization
Authors: Jiang Xiujie , Huang Wei , Luo Sang , Kong Weiyi , Du Kaijun , Wang Yaozheng
Published: January 2024

The butt weld at the connection between orthotropic steel bridge decks (OSBDs) can potentially pose a hazard to the fatigue endurance of the steel bridge deck pavement. This study aims to optimize the parameters of the butt weld seam using finite element (FE) analysis. The optimized parameters will provide valuable guidance for the design of pavements with a focus on antifatigue properties. Initially, the dynamic modulus of the epoxy asphalt mixture (EAM) was determined through laboratory experimentation at various frequencies and temperatures. These material parameters were then used to compute the pavement’s fatigue life. Additionally, a well-established FE model was employed to analyze the deformation and fatigue life of the pavement structure. The validity of the model was verified by the theoretical calculation results. Various factors were considered, including vehicle velocities, pavement temperatures, and weld seam misalignments as well as weld seam dimensions such as height and width. The analysis was conducted using a three-dimensional steel bridge model. The results showed that decreasing pavement temperature, weld seam height, and misalignment led to an increase in pavement fatigue life. Conversely, reducing the weld seam width resulted in a decrease in fatigue life. Furthermore, the study investigated the coupling effect of different weld seam heights and widths on the fatigue life of the pavement. Contour figures were used to establish the parameter relationship formula for weld seam height and width. These findings are significant for pavement and deck designers because they enhance the understanding of the sensitivity of weld seams as design variables affecting the fatigue characteristics of pavement structures. Moreover, special attention should be given to the impact of welding parameters on the fatigue design of steel bridge deck pavement under high-temperature conditions of pavement structures.
A Necessary Role for PKC-2 and TPA-1 in Olfactory Memory and Synaptic AMPAR Trafficking inCaenorhabditis elegans
Authors: Stetak Attila L. , Grenal Thomas , Lenninger Zephyr , Knight Kaz M. , Doser Rachel L. , Hoerndli Frederic J.
Published: January 2024

Protein kinase C (PKC) functions are essential for synaptic plasticity, learning, and memory. However, the roles of specific members of the PKC family in synaptic function, learning, and memory are poorly understood. Here, we investigated the role of individual PKC homologs for synaptic plasticity inCaenorhabditis elegansand found a differential role forpkc-2andtpa-1, but notpkc-1andpkc-3in associative olfactory learning and memory. More specifically we show that PKC-2 is essential for associative learning and TPA-1 for short-term associative memory (STAM). Using endogenous labeling and cell-specific rescues, we show that TPA-1 and PKC-2 are required in AVA for their functions. Previous studies demonstrated that olfactory learning and memory inC. elegansare tied to proper synaptic content and trafficking of AMPA-type ionotropic glutamate receptor homolog GLR-1 in the AVA command interneurons. Therefore, we quantified synaptic content, transport, and delivery of GLR-1 in AVA and showed that loss ofpkc-2andtpa-1leads to decreased transport and delivery but only a subtle decrease in GLR-1 levels at synapses. AVA-specific expression of both PKC-2 and TPA-1 rescued these defects. Finally, genetic epistasis showed that PKC-2 and TPA-1 likely act in the same pathway to control GLR-1 transport and delivery, while regulating different aspects of olfactory learning and STAM. Thus, our data tie together cell-specific functions of 2 PKCs to neuronal and behavioral outcomes inC. elegans, enabling comparative approaches to understand the evolutionarily conserved role of PKC in synaptic plasticity, learning, and memory.
AN IMPROVED DIFFERENTIAL SCANNING CALORIMETRY STUDY FOR THERMAL PROPERTIES OF PEKMEZ SAMPLES ADULTERATED WITH SUGAR SYRUP
Authors: AKTAŞ Nesimi
Published: January 2024

This research was carried out to determine the pH, titratable acidity, ash, specific gravity, color (L*, a*, b*), water activity, electrical conductivity, glass transition temperature (Tg) and melting characteristics of grape and mulberry pekmez samples adulterated with different levels (10%, 30%, 50%) of high fructose corn syrup (HFCS). Ash, titratable acidity and electrical conductivity values have decreased significantly (P<0.05) with the level of adulteration and determined that these properties can be used as a criterion in the determination of adulteration. Two glass transition temperatures occurring between -25.64℃ to -32.58℃ (Tg1) and 23.29℃ to 31.22℃ (Tg2) were detected in all pekmez samples. The single glass transition temperature was determined in the pekmez samples diluted with water, and both the glass transition temperatures and the onset, peak, end temperatures and enthalpy values of the melting peaks increased significantly with the increase in the amount of adulteration (P<0.05).
Gloria Anzaldúa’s Mestiza Pain
Authors: Bost Suzanne
Published: January 2024

Gloria Anzaldúa’s mestiza consciousness has been celebrated by critics of diverse methodologies and applied to discussions of hybridity, borders, and difference around the world. Lost in these wide and varied applications are the conquest and rape, and the regulation of national and individual boundaries, that are the historical origins of mestizaje. I focus on an aspect of Anzaldúa’s work that is often overlooked and that has become even more significant since her recent death: her writings on physical pain. I examine the relationship between these representations and her theories of mestiza consciousness, tracing her references back to Aztec sacrifice rituals and Spanish Catholicism and concluding with a forward-looking analysis of the Chicana feminist political potential of Anzaldúa’s body in pain.
The Sound of G: A Method to Calculate The Acceleration Due to Gravity Using Acoustic Stopwatch
Authors: Pacala F. A. , Pili U.
Published: January 2024

This paper explored to calculate the value of the acceleration due to gravity (g) by using primarily of balloons, mass hanger, an acoustic stopwatch of a smartphone. The acoustic stopwatch used is based on the PhyPhox mobile application. The independent variable was the drop height and the dependent variable is the recorded time. There were seven drop heights and time were recorded for each fall with three repetitions to reduce the error. The computed value of g was comparable to the average value of g of 9.81 m/s and the locally accepted value. The measure value of g is also similar to the findings of various literatures. This proved the ability of the application to measure the drop time with reducing random or systematic errors. The data gathered from this research has proven that simple mobile phone has now tremendous impact in the classroom experiments.  The students now can compute g more than visualizing it. The use of an acoustic stopwatch from a mobile phone in a physics experiment can be a great way for students to gain a better understanding of measuring and interpreting data accurately. The app makes it easier for teachers to demonstrate the concept of measurements and how to properly record them by using audio cues from the phone's built-in microphone.

Authors: Lesmono A. D. , Ramadhan E. B. , Handayani R. D. , Prastowo S. H. B.
Published: January 2024

The lack of teaching materials use, especially in viscosity topics, has decreased students' knowledge and analytical skills in measurement. The research aimed to design a Student Worksheet (LKPD) for viscosity topics to assist and train students in measuring the viscosity of fluids. The fluids used in the experiment were biosolar, dexlite, and pertamina dex, considering that these fuels are among the most significant commodities and widely used in Indonesia. Additionally, the viscosity of diesel fuel is an important property affecting combustion and engine injection. This research employed a quantitative method using laboratory experiments to measure the viscosity values of biosolar, dexlite, and pertamina dex using the falling-ball method. The research findings were utilized to develop the LKPD teaching materials. The results showed that the viscosity values of biosolar fuel, dexlite, and pertamina dex were 3.651 cP; 3.579 cP; and 3.004 cP; respectively. These results differed slightly from the literature but were still deemed suitable for the LKPD teaching material design. The title of the LKPD teaching material used was "Viscosity of Biosolar Fuel, Dexlite, and Pertamina Dex Using the Falling-Ball Measurement Technique," and it followed the format of a cover, usage instructions, summary of the material, laboratory assignments, and questions.

Published: January 2024

Scientific literacy and environmental awareness are skills needed in the 21st century. Therefore, education must provide these skills. This research aims to analyze the effect of SSI-based undergraduate student worksheets on chemical thermodynamics. Pre-experimental research with a pretest-posttest control group design was employed to compare SSI-based and science-based undergraduate student worksheets. Chemistry education students at FKIP Universitas Riau for the 2022/2023 academic year were selected as samples. The experimental and control groups were established based on the homogeneity of their previous academic scores. This study evaluated two outcome variables: scientific literacy ability and environmental awareness. The research instrument is a scientific literacy test using scientific literacy description questions and environmental awareness questionnaires. Scientific literacy test scores were analyzed using the Independent Sample T-test, and environmental awareness questionnaire results were analyzed using the Mann-Whitney U-Test. Increased scientific literacy and environmental awareness of students were analyzed using the N-gain test. The results showed that the experimental group's scientific literacy and environmental awareness were significantly higher than the control group. Therefore, it can be concluded that SSI-based undergraduate student worksheets effectively increase scientific literacy and environmental awareness.
Legal Review of the Validity of the Use of Smart Contracts in Business Transactions in Indonesia and Its Regulation in Various Countries
Authors: Abidin Muhammad Ilman
Published: January 2024

The increasingly massive use of the internet is now affecting the economic world which is characterized by the birth of E-Commerce. E-Commerce mechanism that does not brings together sellers and buyers directly, this raises a variety of problems on the subjective and objective terms of the sale and purchase agreement. Smart Contracts are actually different from conventional contracts written on paper. They are also different from electronic contracts. A clause in the agreement, which takes the form of programming code, requires blockchain as a distributed storage technology, which sets them apart. In addition, Smart Contracts serve to execute contracts automatically. Therefore, the article aims to analyze the advantages of Smart Contracts compared to conventional contracts and how the validity of using smart contracts in Indonesian law, and why business transactions in Indonesia should start using smart contracts. The result obtained is that the use of Smart Contracts are completely automated and rely on software logic, making them transparent and visible to all parties involved. The use of Smart Contract in buying and selling transactions is considered very important considering the advantages in terms of security, verification, changes in the contents of the agreement, and evidentiary power. As for Indonesian law, the use of Smart Contracts is permissible as long as it does not violate the validity of the agreement as stated in the Civil Code. The use of Smart Contracts offer several advantages over traditional contracts, including trasparency, autonomy, speed, accuracy, security, and savings.
Challenges Arising from Article 22(2) of Ministerial Regulation ATR/BPN No. 6/2018 on Complete Systematic Land Registration (PTSL) Pertaining to Insufficient or Missing Evidence of Community Land Ownership
Authors: Taufiq Fida Nabilah , Masykur Mohammad Hamidi , Supriyadi Supriyadi
Published: January 2024

The Complete Systematic Land Registration (PTSL) program's successful implementation hinges on satisfying the physical and juridical data requirements for individual land plots owned by a single person. However, our research highlights disparities between juridical and physical data for specific land plots. Moreover, a lack of community awareness regarding the crucial role of land data collection presents significant challenges in the field. A notable obstacle, as outlined in Article 22(2) of the Regulation of the Minister of Agrarian and Spatial Planning/Head of the National Land Agency of the Republic of Indonesia No. 6 of 2018, pertains to individuals applying for land registration through the PTSL Program without fulfilling complete requirements or providing proof of land ownership. This non-compliance poses a potential catalyst for disputes during the PTSL land registration process. As of early 2017, Indonesia harbored 126,000,000 land parcels, with only 51,000,000 certified and 79,000,000 awaiting official registration, earmarked for acceleration through PTSL. Our focus on Malang Regency in East Java, spanning an expansive 3,534.86 km² or 353,486 ha, reveals its active participation in the PTSL program. Notably, the region faces a substantial PTSL quota of 55,000 land parcels in 2023, distributed across 19 villages in 5 sub-districts, marking the highest quota in East Java Province. The research also underscores the pressing need for enhanced community awareness and compliance with PTSL requirements, particularly focusing on the potential disputes arising from inadequate documentation during the land registration process.
Acoustic and thermal properties of mycelium-based insulation materials produced from desilicated wheat straw - Part B
Authors: Gezer Engin Derya , Kuştaş Süleyman
Published: January 2024

The acoustic and thermal properties were determined for biodegradable insulation materials produced from desilicated wheat straws with two different fungi and three different incubation periods. Ganoderma lucidum (GL) and Pleurotus ostreatus (PO) fungi and wheat straw were exposed to fungal incubation for 10, 20, and 30 days to produce mycelium-based insulation materials. The sound absorption coefficients of mycelium-based insulation boards produced using PO fungus were higher than those produced with GL fungus. It was found that the acoustic absorption coefficients of insulation boards produced using PO fungus at 1,000 Hz were 87 to 99% according to the incubation periods. The sound transmission losses of mycelium-based insulation boards produced ranged from 46.4 to 59.7 dBa at 1000 Hz. The group of boards labeled as YP2 exhibited the lowest level of sound transmission loss, whereas GL2 revealed the highest degree of sound transmission loss at 1000 Hz. The lowest thermal conductivity coefficient was obtained in insulation boards produced with PO fungus and an incubation period of 20 days. The limiting oxygen index (LOI) value of mycelium-based insulation materials was considerably higher than the insulation boards commonly used today. Thermogravimetric analysis and derivative thermogravimetry curves of mycelium-based insulation materials were also determined.

Published: January 2024

El presente artículo tiene como objetivo reflexionar sobre la importancia que reviste la ciudadanía activa como agente impulsor de la creación de políticas públicas dentro de los procesos de gestión que sintonicen con las necesidades de la población. Todo esto enmarcado dentro de una actitud de la ciudadanía que supere y trascienda la incongruencia entre la teoría y la práctica, donde mediante un ethos soberano, asuma un rol protagónico dentro de la sociedad y pueda en la más clara expresión de una práctica ética comprometida con su entorno, persistir en una sociedad más equitativa.
Abriendo las aulas. Los inicios de las excursiones escolares en Lima (1908 - 1918)
Authors: Chipana Rivas Jhonny
Published: January 2024

Este artículo analiza el proceso de incorporación de las excursiones escolares dentro de la práctica educativa regular durante la denominada república aristocrática (1895-1919), impulsada por una política educativa liberal y como parte de una experiencia de modernización de la educación peruana. Las excursiones escolares permitieron la emancipación de la vida educativa, que hasta ese momento se ejercía en ambientes cerrados y desvinculado de la vida nacional, consiguiendo introducir nuevos valores y principios que buscaban despertar curiosidad, racionalidad y participación activa de los estudiantes. No obstante, colisionaron con una fuerza conservadora, de tono militarista, que iba en sentido contrario, provocando que esta experiencia educativa tenga resultados limitados.

Background: Spinal anesthesia has been used for over 120 years as a relatively safe and effective method technique. A well-known anesthetic, bupivacaine is the most widely used local anesthetic in the subarachnoid space. We report a case of prolonged sensory and motor blockade in a patient undergoing spinal anesthesia with 15 mg of 0.5% hyperbaric bupivacaine without any adjuvant, which lasted 32 hours to regress. Case Report: The patient was a 36‑year‑old female, obese, with no known comorbidities, who was undergoing surgical treatment of varicose veins of the lower limbs. Normal pre-operative exams. After sedation with midazolam 2.5 mg, the patient was in a sitting position and 3 attempts at subarachnoid puncture with a 27G cutting needle were unsuccessful. Another attempt with a 25G cutting tip needle was successful and injected 15 mg of 0.5% hyperbaric bupivacaine without adjuvants. The surgical procedure lasted 3 hours without cardio circulatory changes, and the patient was referred to PACU. Ten hours after the persistence of sensory and motor blocks. MRI of the thoracolumbar spine was performed without evidence of alteration. After 17 hours, both sensory and motor blocks remained, requiring bladder catheterization. After 23 hours, the neurological examination was normal, showing the permanence of both blocks. The complete return of sensory and motor blocks occurred after 32 hours, with hospital discharge in 4 hours, after complete regression of the subarachnoid block. Conclusions: In conclusion, an unexpectedly prolonged spinal block can be seen with regular doses of 0.5% hyperbaric bupivacaine. We cannot determine the exact etiology in our present case, with a normal MRI thoracolumbar.

Pais e cuidadores de crianças com a síndrome Prader-Willi (SPW) enfrentam desafios no manejo dos comportamentos característicos do fenótipo comportamental dessa condição, que demandam habilidades parentais que nem sempre fazem parte do seu repertório, o que torna necessário um treino específico. O objetivo do presente estudo foi aplicar e avaliar o Programa de Qualidade na Interação Familiar (PQIF) para pais de crianças com SPW. Sete participantes associados ao ambulatório de SPW do Hospital das Clínicas de São Paulo (ICr-HCFMUSP) participaram do estudo, e medidas foram aplicadas nas fases pré, pós e follow-up. O escore de estilo parental demonstrou aumento no uso de práticas parentais positivas para seis dos sete participantes. Os participantes também apresentaram melhora na auto-observação, ampliação no repertório de análise de comportamentos e de manejo adequado. Limites deste estudo são discutidos, contudo, os dados reforçam a importância de se validar ferramentas que atendam essa população.
Design quality assessment and investigation of visitors satisfaction of the Jordan Museum using Post-Occupancy Evaluation
Authors: Khasawneh Fahed A.
Published: January 2024

The Jordan Museum is the most important modern archeological museum in Jordan. This paper assesses the quality of design and the visitors' satisfaction with the Jordan Museum. Also, it investigates which of the selected performance elements contribute most to visitors' satisfaction. Investigative Post-Occupancy Evaluation (POE) was used within a mixed methodology approach. A questionnaire was used for the quantitative part, complemented by other qualitative methods. Descriptive statistics were used to determine the design quality and visitors' satisfaction. Stepwise regression was used to detect which performance elements predict overall visitors' satisfaction. The design quality of the museum was rated as good, and its permanent galleries were exceptionally rated as excellent. The visitors were generally satisfied with the museum. Visitors were satisfied with the interior and exterior finish but were not impressed with the heavy use of stone in the façade. The simplicity of the museum layout made navigation easy, and visitors were satisfied with wayfinding. This paper is the first to use POE to assess the Jordan Museum. The findings can be used to enhance the management and operation of the Jordan Museum. Also, important performance elements can be developed into guidelines to guarantee effective museum designs in the future.

We report the first record of Gymnothorax longinquus (Whitley, 1948), Long Moray, (Anguilliformes, Muraenidae), from the east coast of Peninsular Malaysia. A single specimen was collected during a bottom-trawl survey in the exclusive economic zone off Malaysia in the South China Sea. Gymnothorax longinquus was previously recorded from populations in Australia, Thailand, the Philippines, and Vietnam. We present detailed morphometric and meristic data, along with brief diagnostic characters.

Published: January 2024

Dual-earner couples in the sandwich generation are overcoming unique challenges to their marital satisfaction. Therefore, this study aimed to explore gender differences in work-family conflict and marital satisfaction in dual-earner couples among the sandwich generation. To achieve this, a quantitative mathod comprising 105 participants (Mage = 39.10; SD = 9.842) from Greater Jakarta, was used. The results showed that there was no significant differences between working men and women in the sandwich generation concerning marital satisfaction and work-family conflict. Based on observations, there was no correlation between work-family conflict and marital satisfaction in women. Conversely, a negative correlation existed between marital satisfaction and the number of children, a trend discovered exclusively in men. In conclusion, this study provided information to improve the marriage quality for dual-earner couples and contributed novel perspective to the discourse on marital satisfaction and work-family conflict.

Published: January 2024

This descriptive qualitative study aimed to comprehend the perception of elementary school children in Bandung about bullying, focusing on the understanding of the phenomenon and the use of social support from teachers, parents, and peers. In order to achieve this aim, semi-structured interviews were carried out with four children aged between 12 to13 years, from different elementary schools in Bandung. The data obtained from the conducted interview were subsequently transcribed and analyzed using a thematic analysis framework. The analysis results showed children comprehended bullying differently in a manner that did not entirely harmonize with the conventional definition. It was also important to acknowledge that children viewed emotional support as a more important factor compared to direct problem-solving. The obtained results were extensively discussed to explore implications for further analysis concerning the interplay between bullying and the association with social support.
