The SaNPF6.3 gene, a putative ortholog of the dual-affinity nitrate (NO3−) transporter gene AtNPF6.3/AtNRT1.1 from Arabidopsis thaliana, was cloned from the euhalophyte Suaeda altissima. The nitrate transporting activity of SaNPF6.3 was studied by heterologous expression of the gene in the yeast Hansenula (Ogataea) polymorpha mutant strain Δynt1 lacking the original nitrate transporter. Expression of SaNPF6.3 in Δynt1 cells rescued their ability to grow on the selective medium in the presence of nitrate and absorb nitrate from this medium. Confocal laser microscopy of the yeast cells expressing the fused protein GFP-SaNPF6.3 revealed GFP (green fluorescent protein) fluorescence localized predominantly in the cytoplasm and/or vacuoles. Apparently, in the heterologous expression system used, only a relatively small fraction of the GFP-SaNPF6.3 reached the plasma membrane of yeast cells. In S. altissima plants grown in media with either low (0.5 mM) or high (15 mM) NO3−; concentrations, SaNPF6.3 was expressed at various ontogenetic stages in different organs, with the highest expression levels in roots, pointing to an important role of SaNPF6.3 in nitrate uptake. SaNPF6.3 expression was induced in roots of nitrate-deprived plants in response to raising the nitrate concentration in the medium and was suppressed when the plants were transferred from sufficient nitrate to the lower concentration. When NaCl concentration in the nutrient solution was elevated, the SaNPF6.3 transcript abundance in the roots increased at the low nitrate concentration and decreased at the high one. We also determined nitrate and chloride concentrations in the xylem sap excreted by detached S. altissima roots as a function of their concentrations in the root medium. Based on a linear increase in Cl− concentrations in the xylem exudate as the external Cl− concentration increased and the results of SaNPF6.3 expression experiments, we hypothesize that SaNPF6.3 is involved in chloride transport along with nitrate transport in S. altissima plants.

Published: October 2023

In this study, indium was added to the binary Mg-Zn alloy to prepare an ultrafine-grained ternary Mg-Zn-In alloy with enhanced mechanical and corrosion properties. The bulk Mg-Zn-In alloy was synthesized through a combination of mechanical alloying and powder metallurgy techniques. The SPEX 8000 mixer mill was used to carry out the process under an argon atmosphere. The mixed powders were mechanically alloyed for 24 h. The mixture was uniaxially pressed at a compacting pressure of 600 MPa. The green compacts were sintered under a protective argon atmosphere at 300 °C for 1 h. The evolution of the microstructural, mechanical, and corrosion properties of Mg-based alloys was studied. X-ray diffraction and scanning electron microscopy were used to analyze the phase and microstructure. The changes in hardness and corrosion properties were also measured. Compared to binary Mg-Zn alloy samples modified with In, the samples exhibited a higher microhardness, which can be related to structure refinement and phase distribution. Based on the results of electrochemical testing, it was observed that the modified samples exhibited an improved level of corrosion resistance compared to the Mg-Zn binary alloy.

Published: October 2023

To evaluate the potential of a bacterial strain as a fungal disease control agent and plant growth promoter, its inhibitory effects on phytopathogens such as Bipolaris sorokiniana, Botrytis cinerea, Colletotrichum capsici, Fusarium graminearum, F. oxysporum, Neocosmospora rubicola, Rhizoctonia solani, and Verticillium dahliae were investigated. The results showed that the inhibitory rates in dual-culture and sterile filtrate assays against these eight phytopathogens ranged from 57% to 83% and from 36% to 92%. The strain was identified as Bacillus velezensis based on morphological and physiological characterization as well as phylogenetic analyses of 16S rRNA and the gyrase subunit A protein (gyrA) regions. The results demonstrated that B. velezensis was able to produce fungal cell-wall-degrading enzymes, namely, protease, cellulase, and β-1,3-glucanase, and the growth-promotion substances indole-3-acetic acid (IAA) and siderophore. Furthermore, B. velezensis BV01 had significant control effects on wheat root rot and pepper Fusarium wilt in a greenhouse. Potted growth-promotion experiments displayed that BV01 significantly increased the height, stem diameter, and aboveground fresh and dry weights of wheat and pepper. The results imply that B. velezensis BV01, a broad-spectrum biocontrol bacterium, is worth further investigation regarding its practical applications in agriculture.

Published: October 2023

Hepatic steatosis can cause liver dysfunction and cell injury, on which natural functional factors are expected to be an effective approach for long-term intervention. However, the cellular molecular mechanisms are unclear. Chlorogenic acid is a phenolic compound, which can regulate lipid metabolism and is abundant in burdock root. The aim of this study was to investigate the potential molecular mechanism of the effect of chlorogenic acid from burdock root (ACQA) on steatosis in HepG2 cells. In this study, we found that ACQA reduced the number of lipid droplets and lipid levels in oleic acid-treated HepG2 cells. Molecular mechanistic results showed that ACQA enhanced CPT-1 expression by activating AMPK-related signaling pathways, and the concentrations of Ca2+ and cAMP were increased with the intervention of ACQA. In addition, ACQA enhanced the β-oxidation of fatty acids, reduced alanine transaminase and aspartate transaminase, and inhibited apoptosis in oleic acid-treated HepG2 cells. Our studies elucidate a novel mechanism that ACQA enhances the β-oxidation of fatty acids through the AMPK/ACC/CPT-1 pathway to protect against steatosis in HepG2 cells, which provides insight into its molecular mechanism as well as intervention strategies for chlorogenic acid against fatty liver diseases.

Published: October 2023

The Ethiopian potato (Plectranthus edulis) is an annual tuber crop indigenous to Ethiopia. The crop is underutilized and not much studied despite its high yield of starch, which has a good potential to contribute to the effort in meeting the quickly growing demand for starch. In this study, the effects of the ecotype and isolation methods on the physicochemical, functional, structural, and crystalline properties of starches were evaluated. Starches were isolated from two Ethiopian potato ecotypes (Loffo and Chanqua) using distilled water (DW), 0.01% sodium metabisulphite (SMS), and 1M sodium chloride (NaCl) in the isolation media. The results showed that the lowest starch yield was obtained from Chanqua using DW (97.4%), while the maximum was from Loffo using SMS (99.3%). The L* (lightness) and whiteness values of the starches obtained from Loffo were higher than those of Chanqua starches, with NaCl and SMS extractants yielding the highest values. The bulk density, water activity (aw), pH, proximate composition (moisture content, protein, ash, fat, crude fiber, and carbohydrate contents), and techno-functional properties were established. The majority of these parameters varied depending on both the isolation method and the ecotype. The crystallinity pattern of all starches showed B-type diffraction, with differences in diffraction peak intensities between all starches. FTIR tests showed structural changes as a function of the ecotype and isolation procedure used. The Loffo ecotype exhibited considerably better results, and the SMS isolation method was found to be the most effective way to acquire the highest starch quality in most of the characteristics evaluated.

Published: October 2023

Sodium-ion batteries have important application prospects in large-scale energy storage due to their advantages, such as safety, affordability, and abundant resources. Prussian blue analogs (PBAs) have a stable and open framework structure, making them a very promising cathode material. However, high-performance manganese-based Prussian blue cathode materials for sodium-ion batteries still suffer from significant challenges due to several key issues, such as a high number of vacancy defects and a high crystal water content. This article investigates the effects of the Fe-Mn molar ratio, Mn ion concentration, and reaction time on the electrochemical performance of MnHCF during the coprecipitation process. When Fe:Mn = 1:2, c(Mn2+) = 0.02 mol/L, and the reaction time is 12 h, the content of interstitial water molecules in the sample is low, and the Fe(CN)6 defects are few. At 0.1 C, the prepared electrode has a high initial discharge specific capacity (121.9 mAh g−1), and after 100 cycles at 0.2 C, the capacity retention rate is 65% (~76.2 mAh g−1). Meanwhile, the sample electrode exhibits excellent reversibility. The discharge capacity can still be maintained at around 75% when the magnification is restored from 5 C to 0.1 C. The improvement in performance is mainly attributed to two aspects: On the one hand, reducing the Fe(CN)6 defects and crystal water content is conducive to the diffusion and stable structure of N. On the other hand, reducing the reaction rate can significantly delay the crystallization of materials and optimize the nucleation process.

Published: October 2023

Bi2O2Se, as a novel two-dimensional semiconductor material, has been prepared and used in the field of photodetection. Herein, Bi2O2Se nanosheets were prepared using a hydrothermal method. Bi2O2Se films were also prepared using a drop-coating method. A photoconductive detector based on the Bi2O2Se film was constructed. The influence of nanosheet size was considered. Ultrasonic crashing treatments and different drying processes were used for the improvement of device performance. The obtained results demonstrate that the Bi2O2Se film based on treated nanosheets is denser and more continuous, leading to a higher photocurrent (1.4 nA). Drying in a vacuum can further increase the photocurrent of the device (3.0 nA). The photocurrent would increase with the increase in drying temperatures, while the dark current increases synchronously, leading to a decrease in the on/off ratio. The device based on Bi2O2Se film was dried in a vacuum at 180 °C and exhibited high responsivity (28 mA/W) and detectivity (~4 × 109 Jones) under 780 nm light illumination. Together, these results provide a data foundation and vision for the further development of photodetectors based on Bi2O2Se material.

Authors: Rusková Renáta , Račko Dušan
Published: October 2023

We performed coarse-grained molecular dynamics simulations of DNA polymers pushed inside infinite open chiral and achiral channels. We investigated the behavior of the polymer metrics in terms of span, monomer distributions and changes of topological state of the polymer in the channels. We also compared the regime of pushing a polymer inside the infinite channel to the case of polymer compression in finite channels of knot factories investigated in earlier works. We observed that the compression in the open channels affects the polymer metrics to different extents in chiral and achiral channels. We also observed that the chiral channels give rise to the formation of equichiral knots with the same handedness as the handedness of the chiral channels.

Porous TiO2-doped polyaniline and polyaniline nanocomposite fibers prepared by the in situ polymerization technique using anionic surfactant in an ice bath were studied. The prepared nanocomposites were characterized by FTIR spectroscopy and XRD patterns for structural analysis. The surface morphology of the polyaniline and its nanocomposites was examined using SEM images. DC conductivity shows the three levels of conductivity inherent in a semiconductor. Among the nanocomposites, the maximum DC conductivity is 5.6 S/cm for 3 wt.% polyaniline-TiO2 nanocomposite. Cyclic voltammetry shows the properties of PANI due to the redox peaks of 0.93 V and 0.24 V. Both peaks are due to the redox transition of PANI from the semiconductor to the conductive state. The hydrogen absorption capacity is approximately 4.5 wt.%, but at 60 °C the capacity doubles to approximately 7.3 wt.%. Conversely, 3 wt.% PANI—TiO2 nanocomposites have a high absorption capacity of 10.4 wt.% compared to other nanocomposites. An overall desorption capacity of 10.4 wt.% reduced to 96% was found for 3 wt.% TiO2-doped PANI nanocomposites.

Published: October 2023

This paper introduces, describes, and compares the energy storage technologies of Compressed Air Energy Storage (CAES) and Liquid Air Energy Storage (LAES). Given the significant transformation the power industry has witnessed in the past decade, a noticeable lack of novel energy storage technologies spanning various power levels has emerged. To bridge this gap, CAES and LAES emerge as promising alternatives for diverse applications. The paper offers a succinct overview and synthesis of these two energy storage methods, outlining their core operational principles, practical implementations, crucial parameters, and potential system configurations. The article also highlights approaches to enhance the efficiency of these technologies and underscores the roles of thermal energy storage within their processes. Furthermore, it delves into the discussion of the significance of hybrid systems and polygeneration in the contexts of CAES and LAES technologies. Moreover, we briefly explore the potential integration of these technologies into other power systems.
Combined Bacterial and Pressure Oxidation for Processing High-Sulfur Refractory Gold Concentrate

Published: October 2023

Microbially assisted bio-oxidation of sulfide concentrates in stirred-tank reactors (stirred-tank reactor bio-oxidation (STRB)) and acid pressure oxidation (POX) are widely used to pretreat refractory sulfide concentrates and increase gold extraction via cyanidation. Continuous STRB requires a comparatively long residence time; however, in some cases, it cannot effectively oxidize some sulfide minerals. POX enables oxidation in a short residence time. At the same time, if a processed concentrate contains a large amount of sulfur, it decreases the ratio of the solid mineral phase to liquid (pulp density) during POX and limits its economic attractiveness. In the present work, experiments were performed to investigate the problems associated with both processing methods for refractory sulfide concentrates. The experiments combined both treatments (STRB and POX) based on the example of a pyrite–arsenopyrite gold-bearing concentrate. The gold recovery from the untreated concentrate via cyanidation reached 58%. Continuous STRB for 2, 4, and 6 days oxidized 43, 74, and 79% of the sulfide sulfur (Ss), respectively. The gold recovery rates from the bio-oxidation residues were 68, 82, and 88%, respectively. The pressure oxidation of both the concentrate and STRB residues increased Ss oxidation by 97–99% and gold recovery by 96–97%. For 2 days, STRB decreased the Ss content and increased the possible liquid-to-solid ratio for POX. The combined processes result in a new promising direction because the POX stage allows high gold recovery, whereas combining STRB and POX provides products for further POX in terms of Ss content and increases POX productivity.
Justice at the House of Yhw(h): An Early Yahwistic Defixio in Furem
Authors: Barnea Gad
Published: October 2023

What was the nature of ritual in ancient Yahwism? Although biblical sources provide some information about various types of cultic activity, we have thus far lacked any extra-biblical ritual texts from Yahwistic circles prior to Greco–Roman times. This article presents such a text—one that has been hiding in plain sight for almost a century on a small ostracon found on the island of Elephantine. It has variously been interpreted as dealing with instructions regarding a tunic left at the “house of Yhw”—the temple to Yhw(h) that flourished on the island from the middle of the sixth to the end of the fourth century BCE. While there is little debate regarding the epigraphic reading of this text, it has hitherto failed to be correctly interpreted. I present an entirely new reading of this important document, revealing it to be written in poetic form and to match the characteristics of a “prayer for justice” curse ritual. It is, in fact, the oldest known example of this genre; its only known specimen in Aramaic, its unique witness in a Yahwistic context, and the sole record of any ritual performance at a temple to Yhw(h). Significantly, it is administered by a priestess.
A Post-Secular Approach to Managing Diversity in Liberal Democracies: Exploring the Interplay of Human Rights, Religious Identity, and Inclusive Governance in Western Societies
Authors: Sajir Zakaria
Published: October 2023

This article delves into the pressing challenges confronting liberal democracies in Western Europe as they grapple with managing religious diversity, with a specific focus on Muslim minorities. Historically, the secularization paradigm has been at the forefront of managing such diversity; however, its intrinsic limitations become increasingly evident in the context of super-diversity, underscoring the need for a paradigmatic shift toward post-secularization. Central to this discourse are the nuanced concepts of “culturalization of religion” and “religionization of culture”, which illuminate the disparities in treatment between majority and minority religious groups. The article identifies three endogenous limitations intrinsic to liberal democracies: the contested nature of state neutrality vis-à-vis religion and belief, the implementation of this principle through non-neutral judicial tools, and the historically and culturally laden context within which the principle of neutrality is enacted. Drawing on the seminal contributions of Jürgen Habermas to post-secularization theory, the article posits that fostering genuine inclusivity and pluralism in managing religious diversity necessitates a departure from the rigid division between the religious and the secular. Instead, it calls for an acknowledgment of the dialogical relationship between the religious and secular dimensions as they manifest in the public sphere by religious minorities.
Enhanced Feature Extraction Network Based on Acoustic Signal Feature Learning for Bearing Fault Diagnosis
Authors: Luo Yuanqing , Lu Wenxia , Kang Shuang , Tian Xueyong , Kang Xiaoqi , Sun Feng
Published: October 2023

The method of acoustic radiation signal detection not only enables contactless measurement but also provides comprehensive state information during equipment operation. This paper proposes an enhanced feature extraction network (EFEN) for fault diagnosis of rolling bearings based on acoustic signal feature learning. The EFEN network comprises four main components: the data preprocessing module, the information feature selection module (IFSM), the channel attention mechanism module (CAMM), and the convolutional neural network module (CNNM). Firstly, the one-dimensional acoustic signal is transformed into a two-dimensional grayscale image. Then, IFSM utilizes three different-sized convolution filters to process input image data and fuse and assign weights to feature information that can attenuate noise while highlighting effective fault information. Next, a channel attention mechanism module is introduced to assign weights to each channel. Finally, the convolutional neural network (CNN) fault diagnosis module is employed for accurate classification of rolling bearing faults. Experimental results demonstrate that the EFEN network achieves high accuracy in fault diagnosis and effectively detects rolling bearing faults based on acoustic signals. The proposed method achieves an accuracy of 98.52%, surpassing other methods in terms of performance. In comparative analysis of antinoise experiments, the average accuracy remains remarkably high at 96.62%, accompanied by a significantly reduced average iteration time of only 0.25 s. Furthermore, comparative analysis confirms that the proposed algorithm exhibits excellent accuracy and resistance against noise.

Published: October 2023

Significant environmental and social issues confront the textile and apparel industries, including resource depletion and excessive textile waste. Implementing circular economy principles is essential for the sustainability of this industry. The present paper is a bibliometric analysis study type designed to identify collaborative networks, prolific countries, journals, and influential articles pertaining to the implementation of the circular economy in the textile and apparel industries that may serve as a starting point for an in-depth understanding of the subject, facilitating the knowledge of essential bibliometric parameters for pre-publication phases. The data were extracted from the Web of Science and analyzed using both the Web of Science web interface and the VOSviewer software version 1.6.19. The bibliometric data were divided into two distinct periods to analyze the evolution of this subject over time: from 1975 to 2010 and from 2011 to 2023. In the first period, the most productive country was the United States, with 527 publications, accounting for 10.81% of the scientific output during that time. In the second period, China emerged as the most productive country, with 2478 published documents, constituting 18.44% of the total production in this period. During the first period, Istanbul Technical University was the most active institution, with 91 publications (1.87% of the total production), while in the second period the Indian Institute of Technology System was the most productive, with 265 documents (1.95%). These key findings demonstrate the textile industry’s commitment to sustainable and environmentally friendly practices. They also highlight the industry’s adoption of advanced technologies and its exploration of new research areas; but there is still room for improvement, which is why continuous research implemented through future research areas is essential.

Authors: Luo Yong , Chen Dianpeng , Wang Xiaoguo
Published: October 2023

China stands as one of the world’s largest agricultural powerhouses, boasting abundant crop resources. Nonetheless, there remains a lack of clarity regarding the extensive scale of crop residue return in the fields. Drawing from direct field measurements and comprehensive survey data, this paper pioneers the reporting of residues from the five primary crops, shedding light on the associated nutrient components, including carbon (C), nitrogen (N), and phosphorus (P) replenishment via crop roots, stubble, and straw in the Southwest China region for the year 2012. The results showed that the total amount of the main crop residue resources was 97.4 Mt, which was composed of 17.8 Mt, 12.6 Mt, and 67 Mt for crop root, stubble, and straw, respectively. After crops harvested, there were 7165.8 kilotonne nutrient C, 132.2 kilotonne nutrient N, and 9.8 kilotonne nutrient P of crop residues returned to the fields through crop root, respectively, accounting for 44.6%, 48.2%, and 43.4% of the total nutrient returned, which was the main part of crop nutrients return to fields. The amount of nutrient C, N, and P returned through stubbles were 5017.3 kilotonne, 75.9 kilotonne, and 6.8 kilotonne, respectively, accounting for 31.3%, 27.6%, and 30.6% of the total return of crops. From the composition proportion of residues nutrients return to field, the orders were all expressed as follows: root > stubble > straw. According to the optimum fertilization amount of the main crops in Southwest China, the returned of crop residues nutrient N in maize, rice, rapeseed, and wheat can replace approximately 5.6%, 18.4%, 11.2%, and 14.8% of nitrogen fertilizer, and 2.4%, 8.3%, 3%, and 9.2% of phosphate fertilizer, respectively. This conclusion is beneficial for regulating the practice of returning crop residues to the fields and the use of agricultural fertilizers, aiming to achieve sustainable development in agricultural production.

Published: October 2023

In order to derive sodium abundances and investigate the effects of non-local thermodynamic equilibrium (NLTE) on the formation of H-band Na I lines, we update the sodium atomic model by incorporating collision rates with hydrogen from new quantum-mechanical calculations. The differential Na abundances for 13 sample stars are obtained by analyzing high-resolution H-band spectra from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) and optical spectra under both local thermodynamic equilibrium (LTE) and NLTE conditions. Consistent abundances from both bands suggest that our updated atomic model is valid for studying the formation of H-band Na I lines. Our calculations show that, in our stellar parameter space, NLTE effects are negative and can result in corrections larger than −0.4 dex on optical lines. The corrections on H-band Na I lines are typically small, within about 0.05 dex, but not negligible if accurate sodium abundance is desired. We note that the [Na/Fe] ratios favor the theoretical galactic chemical model.

Concluding with suggestions for future research, this study aims to propel the progression of academic librarianship and the enhancement of e-learning outcomes.
Students’ Acceptance Of Digital Exams: A Case Study In A Swedish University
Authors: Chatzipetrou Panagiota , Majkic Kristijan , Samuelsson Jonas , Åberg Oskar
Published: October 2023

In this paper we present the results  of a case study in a Swedish university regarding students’ acceptance of digital exams. Technology Acceptance Model (TAM), which has been widely used in research concerning technology acceptance, was used to measure the level of students’ acceptance of digital exams. The aim of the study is to investigate students’ acceptance of digital exams and if there are any factors that are responsible for this behavior. A survey based on the two main factors of TAM, perceived ease of use and perceived usefulness, was conducted. The survey was targeting the degree of acceptance along with students’ demographic characteristics. The results showed that the students demonstrated a high degree of acceptance of digital exams, with students in their second and third year having a more positive perception rather than students in their first year. However, other factors, such as gender, subject, and age did not appear to have a strong impact on the overall acceptance of digital exams but did show a moderate impact on external factors such as perceived accessibility and computer self-efficacy, which work as predictors for perceived ease of use for a system. Overall, the knowledge about the level of acceptance of the students is valuable since we can highlight strengths and weaknesses associated with digital exams. This can be a useful tool in deciding upon a suitable digital solution for digital exams, as well as in learning how to increase the level of acceptance among the students in the future.

In this study, it is aimed to determine the relationship between mental health and work performance levels of hospital employees and occupational health and safety culture. The study is cross-sectional, and was conducted in 2022 among employees of a university hospital. No sample selection was made in the study, and the study was conducted with 208 people who agreed to participate in the study. Data were collected using a socio-demographic questionnaire, Occupational Health and Safety Culture (OHSC) scale, Depression-Anxiety-Stress Scale (DASS-21) and Work Performance Scale (WPS). Data were evaluated by ANOVA, correlation and linear regression analysis. Of the employees, 33.7% stated that their duration of work in the institution is less than 3 years, 84.6% of them received in-service training about OHSC, and 41.3% of them stated that their knowledge about OHSC is sufficient. In order of importance, the OHSC total score average is increased by decreasing the duration of work in the institution (β= -0.352), receiving in-service training at OHSC (β=0.209), increasing work performance (β=0.190) and working as medical staff (β=0.183) (p<0.05), while depression, anxiety, stress, age, gender, marital status, income level, health perception, and received OHS training were not found statistically significant (p>0.05). The OHS culture level of the hospital employees is medium, and the increase in work performance is to increase the OHSC level. No relationship was found between OSHC and mental status. Hospital administrations should implement policies that increase the OHS culture and work performance in the institution.

Özenli çalışma ve yoğun çaba gerektiren bilimsel araştırma süreçleri ile araştırma sonuçlarının sayın dergilerde yayınlanması bir yandan bilimin bir yandan da bilim insanının gelişmesine katkı sağlamaktadır. Bilişim ve bilgi teknolojilerindeki gelişmelere paralel olarak bilimsel çalışmalarda ve yayınlarda da hızlı bir artış olmaktadır. Ne var ki bu hızlı artış sırasında önemli yöntem hatalarına sahip pek çok araştırma sonucunun saygın bilim dergilerinde yayın olarak yer alabildiği, kısa sürede çok sayıda atıf alabildiği görülmektedir. Bu sorunu ifade etmek amacıyla kullanılan “tekrar edilebilirlik krizi” tartışmaları bilimsel çalışma ve yayınlarda açıklık, şeffaflık özelliklerinin önkoşul olması gerektiğini göstermektedir. Bu amaçla her türlü bilimsel araştırma için ön-kayıt uygulamasının bir kural olması, hakem değerlendirmelerinin sadece yayın aşamasında değil araştırmanın her aşamasında yapılabilmesi hatta kamusal değerlendirmenin mümkün olması, bilimsel saygınlığın ve bilime güvenin korunması için “açık bilim” uygulamalarının yaygınlaşması gerekmektedir.

Penelitian ini bertujuan untuk menelusuri pengembangan studi tentang pemilu dan digitalisasi secara global dan tantangannya di Indonesia melalui analisis bibliometrik. Penelitian ini menggunakan data bibliografi dari database Scopus, dengan fokus pada publikasi yang terkait dengan digitalisasi dalam konteks pemilihan umum. Hasil penelitian menunjukkan bahwa penelitian tentang pemilu dan digitalisasi terus berkembang sejak tahun 1993, terutama di negara- negara maju seperti Inggris, Jerman, dan Amerika Serikat. Namun, penelitian tentang pemilu dan digitalisasi di Indonesia masih terbatas, meskipun ada beberapa publikasi yang relevan. Studi tentang pemilu dan digitalisasi secara global telah menunjukkan bahwa digitalisasi dapat memberikan manfaat bagi proses pemilu, seperti mempercepat penghitungan suara, memudahkan pemilih untuk memperoleh informasi terkait calon dan partai politik, serta meningkatkan partisipasi pemilih. Namun, terdapat juga beberapa tantangan dan risiko yang perlu diwaspadai dalam menerapkan digitalisasi dalam pemilu di Indonesia, seperti kesiapan teknologi dan infrastruktur Internet, keamanan siber, privasi data, dan potensi terjadinya kecurangan pemilu. Hal tersebut sangat membutuhkan respon pemerintah, termasuk penyelenggara pemilu. Itu dapat dilakukan dengan mempersiapkan aspek pendukung secara baik seperti penerapan inovasi teknologi komunikasi, penguatan sistem keamanan data, memperbaiki infrastruktur pendukung, dan penguatan regulasi yang memadai.
