Authors: Du Siyao
Published: January 2025

Vocabulary acquisition is a fundamental component of English language learning and is widely recognized for its critical role in effective communication and overall language proficiency. Given its importance, the evaluation of teaching materials, particularly textbooks, is essential for enhancing the quality of vocabulary instruction. This study focuses on analyzing the vocabulary teaching approach in the Contemporary College English (First Volume), a textbook designed for first-year English majors in China. The analysis excludes the exam units (Units 7 and 14) and concentrates on Text A of each unit, as it constitutes the primary instructional content. Specifically, the vocabulary section is examined in three key areas: word formation, formulaic language, and synonyms and antonyms. The study evaluates the textbook's adherence to the Principled Communicative Approach and identifies areas for improvement in its vocabulary teaching methods. After the analysis, the study applies the Principled Communicative Approach to evaluate whether the textbook’s design aligns with its principles. The findings indicate that while the vocabulary design of the textbook largely adheres to the core tenets of the Principled Communicative Approach, there remains significant room for improvement in several areas.

Representasi Tuhan Dalam Kitab Keluaran: Analisis Historis-Teologis Dan Relevansinya Dalam Konteks Modern
Authors: Kawengian Yohana , Tumbel Karenadia , Lape Junia
Published: January 2025

Kitab Keluaran merupakan bagian kedua dari Pentateukh yang mengandung narasi penting dalam tradisi Yahudi dan Kristen. Artikel ini mengkaji representasi Tuhan dalam Kitab Keluaran dari perspektif historis, teologis, dan relevansinya di era modern. Kajian sebelumnya cenderung memisahkan dimensi historis dan teologis, sehingga relevansi keduanya dalam konteks modern belum dieksplorasi secara mendalam. Penelitian ini bertujuan untuk mengisi gap tersebut dengan menggunakan pendekatan kualitatif melalui analisis teks, kajian tematik, pendekatan historis-kritis, dan refleksi teologis. Hasil penelitian menunjukkan bahwa Tuhan dalam Kitab Keluaran direpresentasikan sebagai pembebas, pemimpin, dan pemberi hukum yang secara aktif membentuk identitas bangsa Israel. Dari perspektif historis, Tuhan muncul dalam konteks pembebasan dari penindasan, sedangkan secara teologis, Tuhan menunjukkan sifat kasih, keadilan, dan kehadiran-Nya yang nyata. Dalam konteks modern, narasi ini memberikan inspirasi dalam perjuangan keadilan sosial, integritas kepemimpinan, dan penerapan nilai-nilai etis. Dengan demikian, penelitian ini menawarkan perspektif baru yang menghubungkan tradisi kitab suci dengan tantangan moral dan spiritual masa kini.
Analisis Biblikal Mengenai Kedatangan Yesus Kristus Kedua Kali Berdasarkan Kisah Para Rasul 1:11
Authors: Ajais Yalisu  , Feni Tiara  , Jarna sari
Published: January 2025

Artikel ini memberikan penegasan bahwa kedatangan Yesus Kristus kedua kali merupakan inti dari pengharapan eskatologis umat kristen. Pemahaman terhadap peristiwa ini terbagi dalam berbagai pandangan yang berbeda yakni postmilenialisme, amilenialisme, dan premilenialisme. Masing-masing pandangan ini memiliki dasar teologis dan pendekatan penafsiran yang berbeda, baik dalam melihat peran Israel maupun gereja. Dalam premilenialisme, khususnya dispensasionalisme kedatangan Yesus dilihat secara literal dengan pemisahan peran antara Israel dan gereja. Pandangan dispensasional ini memperjelas perbedaan antara Rapture dan kedatangan Yesus yang kedua kali, yang dimana Rapture akan terjadi sebelum masa kesengsaraan besar, sedangkan kedatangan kedua Yesus terjadi setelahnya untuk menegakkan Kerajaan Seribu Tahun. Diluar memisahkan tahapan ini, pandangan ini juga mengungkap penggenapan janji Allah kepada Israel yang dipahami sebagai peran eskatologis khusus, dengan Israel sebagai subjek dari berbagai janji yang secara spesifik akan laksanakan pada akhir zaman. Selain itu, pendekatan ini mempertegas janji pemulihan bagi Israel, yang dianggap sebagai penggenapan janji Allah kepada bangsa tersebut dan melihat peran eskatologis Israel secara literal dalam pemerintahan Kristus di bumi. Penelitian ini memberikan peran pada pemahaman teologi eskatologis yang lebih jelas dan sistematis bagi uat Kristen, dengan berdasarkan perspektif dispensasionalisme. Dengan demikian, umat Kristen diharapkan memiliki pemahaman yang lebih tepat tentang kedatangan Kristus kedua kali, serta mampu menghadapi berbagai ajaran yang menyimpang dari doktrin utama gereja.

Evaluation of changes in virulence gene expression in Salmonella enterica serovar Enteritidis resulting from deletion of genes associated to the excision of the pathogenicity island ROD21.
Authors:   , Suazo Gálvez Isidora del Carmen
Published: January 2025

Pathogenicity islands (PAIs) are mobile genetic elements acquired by horizontal gene transfer in bacteria. Some PAIs have been described as excisable elements, in which the excision process involves several proteins that are encoded within and outside the PAIs, among them, an integrase and a recombination directionality factor (RDF). This process is involved in the regulation of bacterial gene expression and virulence. Salmonella enterica serovar Enteritidis (SEn) is a pathogenic Gram-negative bacteria, which possesses several PAIs. One of them, known as ROD21, is an excisable PAI that has been linked to virulence in mice and poultry. In the case of ROD21, the genes SEN1970 and SEN1998 encode an integrase and an RDF, respectively. We developed a new mutant SEn strain lacking both SEN1970 and SEN1998 which in contrast to previous results showed us that the lack of these genes in SEn has no significant effect on the frequency of ROD21 excision, but it indeed has an impact on the transcriptional pattern of SEn, particularly affecting the transcription of genes located in SPI-2. In vivo experiments in mice also showed a differential capacity of our mutant SEn to reach levels of colonization at later stages of infection, as compared to the wild-type SEn strain. These results have led us to conclude that SEN1970 and SEN1998 are not essential for ROD21 excision but do have a possible role in regulating the transcription of virulence genes located in other pathogenicity islands, affecting the ability of SEn to cause systemic infection in mice.
Configuraciones del conocimiento ambiental : el lugar como experiencia pedagógica y acción comunitaria
Authors:   , Condeza Marmentini Antonia
Published: January 2025

A pesar de que aún el ámbito formal la educación relativa al ambiente permanece marginal, este campo es de creciente interés en todos los ámbitos educativos de nuestro país. Sin embargo, y en la práctica, las políticas que promueven la Educación para el Desarrollo Sustentable no parecen aportar a la problematización del ambiente y la sustentabilidad desde una perspectiva educativa, ni tampoco impulsar versiones basadas en perspectivas comunitarias. En ese contexto y desde las epistemologías de la complejidad, esta Tesis tiene como propósito plantear alternativas al desafío de desarrollar propuestas pedagógicas pertinentes a distintos contextos socio-culturales. Se destacan diferentes sentidos del ambiente en sus configuraciones en interrelación, interpretando el conocimiento ambiental que emerge en la experiencia pedagógica desde la voz de los estudiantes y de los profesores. Los estudiantes expresan un itinerario de configuración de conocimiento ambiental de estructura compleja, desde la que se releva la emergencia del lugar como eje de sentido de la experiencia vivida de los estudiantes. Entre los profesores, se destacan prácticas asociadas a sus propósitos de largo plazo a través de los que se desarrollan diferentes formas de abordar el desafío de configurar perspectivas del ambiente y de determinadas visiones de la educación. Desde la Escuela, ambas perspectivas resaltan la construcción de un conocimiento en “red” que implica diversos niveles de conocimiento y destaca el lugar como condición de la experiencia educativa. El carácter intersubjetivo y situado del conocimiento ambiental da origen a la discusión sobre el valor de una propuesta de educación ambiental contextualizada, que promueva la construcción de posibilidades y de espacios para la emergencia de sentidos y de la acción.

En busca del tiempo perdido : el origen del rock chileno en Santiago, 1945-1967
Authors:   , Albornoz Cuevas César
Published: January 2025

El presente trabajo es una historia del rock chileno sobre la base de la búsqueda y encuentro de los orígenes del género en la capital nacional. Desde un análisis acerca la relevancia del rock para la historia contemporánea y su acercamiento desde la disciplina historiográfica, se construye una definición desde la historia de “Rock”, consideración que se refiere a su experiencia social y cultural marcada por características como la transgresión, la denuncia de la contingencia, la libertad sonora y la pertenencia generacional. Ésta se transforma en el eje de la pregunta sobre desde cuándo tenemos rock en Chile y por qué. Los antecedentes se remontan a los albores del siglo XX en Santiago, tiempo en que la música popular masiva en Chile de a poco iba manifestando variables que, a lo largo de los años, iban a ser constituyentes del rock chileno. Se realiza un recorrido diacrónico que recorre parte importante del tiempo veinteno, para concluir el recorrido en la década de 1960, tiempo en el que se afirma nace el rock chileno en Santiago. El trabajo tiene cuatro ideas-fuerza que es bueno explicitar. Primero, se aferra altratamiento de las manifestaciones culturales desde la perspectiva del largo tiempo, remontándose un evento a décadas atrás en su origen. Esto se condice con la propia experiencia del investigador: el trabajo es, en el fondo, el resultado de un largo de tiempo de investigación y vida vinculada a su objeto de estudio. Segundo, analiza un objeto artístico en la dimensión temporal de su sociedad, transformándose éste –en este caso, el rock- en una representación simbólica que da cuenta de tiempo pasado a través de los vestigios que generó y que le dan su historicidad. Tercero, esos vestigios son documentos escritos, pero sobre todo sonoros, iconográficos y audiovisuales. Esta característica condujo a atender y desarrollar el trabajo de este tipo de fuentes para la comprensión de la historia, considerando como indicios efectivos tanto fuentes escritas como discos, carátulas, fotografías y películas. Ello, además de la memoria, fueron piezas fundamentales de la historia presentada. Finalmente, este texto es una historia contemporánea de Chile a la luz de una experiencia artística cultural masiva. No se instala en la historia del arte o de la música en cuanto considera su expresión como objeto descifrable desde sí a lo largo del tiempo; se perfila en la historia del rock en cuanto expresión cultural de una sociedad con espacio y tiempo, que puede ser comprendida desde sus representaciones simbólicas. No es una historia social de la música chilena; es una historia musical de la sociedad chilena del siglo XX.
Intensity and variability of interpersonal problems in people diagnosed with borderline personality disorder: An ecological momentary assessment study
Authors:   , Daveggio Urzua Magdalena
Published: January 2025

This paper examines the interpersonal difficulties that are prevalent in individuals diagnosed with borderline personality disorder (BPD), a condition that affects an estimated 1.8% to 5% of the global population (Winsper et al., 2020; Chapman et al., 2022; Gunderson, 2018). The research focuses on four key areas of the interpersonal difficulties: feelings of rejection, alienation, variability in interpersonal patterns, and frequency of interpersonal conflicts (Gunderson, 2014). Using Ecological Momentary Assessment (EMA), a method involving real-time data collection across daily natural settings, this study captured interpersonal interactions over a 5-day period, with participants responding to prompts 13 times daily. By comparing data from a BPD group to a healthy control group, the research aims to quantify differences in the frequency, variability, and intensity of interpersonal challenges specific to BPD. The central question of this research addresses how these patterns differ across the areas of rejection, alienation, and conflict between individuals with BPD and those without. The findings from this study may provide that there are in fact differences between the healthy population and the BPD individuals.

Authors: Chandra Richa , Misra Gaurav , Bisht Navneeta , Dutta Gopal , Khandelwal Sumit
Published: January 2025

Situs inversus is a rare congenital anomaly and presents with transposition of abdominal and thoracic viscera to the opposite side, including the heart and gallbladder. Laparoscopic Cholecystectomy (LC) is the gold standard for chronic cholelithiasis and has been reported in patients with situs inversus under General Anaesthesia (GA). Segmental Spinal anaesthesia (SS) has been gaining popularity as a safe alternative to GA in high-risk patients and for LC as well. Present case is of a 48-year-old male with situs inversus, dextrocardia without any other cardiopulmonary anomaly, and short stature who was electively operated on under the SS for chronic cholelithiasis electively. The patient was aware of his congenital condition and preferred awake anaesthesia. After a multidisciplinary discussion involving surgery, cardiology and the anaesthesia team the patient was operated on with LC successfully under SS with isobaric levobupivacaine and fentanyl through T8-9 space. The intraoperative and postoperative periods were uneventful. Present case conclude that SS can provide considerable safety in well-investigated patients who pose a risk for GA due to various factors, such as altered anatomy, birth abnormalities associated with cardiac and pulmonary risk and difficult airways. This case report can be used as a reference for the preferred use of SS instead of GA in such cases.

Published: January 2025

Background: Caesarean section is a common surgical procedure in Obstetrics.  Despite the safety in carrying out caesarean section, it is still associated with blood loss and need for blood transfusion when compared to women who had vaginal delivery. Despite the use of uterotonic such as oxytocin, to prevent postpartum haemorrhage, excessive bleeding still occurs during and after caesarean section. Melatonin has been shown to reduce blood loss, which may be useful in prevention of postpartum haemorrhage. Hence, we aimed to determine the efficacy of Melatonin in reducing blood loss during and after elective caesarean section.
Methodology: This was a double-blind randomised controlled trial. Data analysis was done using IBM SPSS (version 25, Chicago II, USA). Continuous variables were presented as mean and standard deviation (Mean ± 2SD), while categorical variables were presented as numbers and percentages. The categorical variables were analysed using Chi square, while means were compared using t-test and Mann-Whitney U test for non-parametric. A P value <0.05 was considered statistically significant.
Result: Sublingual melatonin reduced blood loss by an average of 76.67ml (0.44%) at elective caesarean section compared with placebo group (955.00ml versus 1031.67ml respectively), however this was not statistically significant  (p-value = 0.097). Participants that received blood transfusion were higher in placebo group than melatonin group {29 (17.9%) versus 19 (11.7%)} however, the difference was not statistically significant (p-value = 0.159. Moreover, participants that required additional oxytocic were also higher in placebo group compared to melatonin group {45(27.8%) versus 34 (21.0%)} however, the difference between the two was not statistically significant, (p-value is 0.196). There was no major maternal or neonatal side effect.
Conclusion: This study demonstrated that 8mg sublingual melatonin did not significantly reduce blood loss at elective caesarean section. However, more participants in the placebo group required more oxytocic and blood transfusion. So higher doses and/or repetitive doses should be explored in future researches.

Authors: Balogun Adebayo Yusuf
Published: January 2025

This study evaluates the state of data privacy and cybersecurity compliance within the U.S. healthcare sector, leveraging data from the U.S. Department of Health & Human Services Breach Portal, Verizon Data Breach Investigations Report, and the Health IT Dashboard. A quantitative methodology comprising descriptive statistical analysis, K-means clustering, and multivariate regression was employed to examine healthcare data breaches, categorize cybersecurity threats, and identify compliance challenges. Findings revealed a persistent increase in breaches, with hacking/IT incidents comprising over 80% of breaches in 2020 and a peak of 135 incidents in 2021. Budget allocation emerged as the most significant predictor of compliance (p = 0.0178), affirming resource constraints. Malware and ransomware were identified as dominant threats, while insider threats emerged as high-impact vulnerabilities. The study recommends increasing cybersecurity budgets, implementing continuous staff training, harmonizing regulations, and adopting Cybersecurity Maturity Models to systematically enhance security postures.  The study provides critical insights into the challenges faced by healthcare organizations in achieving compliance with evolving data privacy regulations such as HIPAA and HITECH. The findings highlight the economic and operational implications of non-compliance, including financial penalties, reputational harm, and patient trust erosion. The study further affirms the importance of strategic investments in advanced cybersecurity tools, policy harmonization, and employee education. Hence, policymakers and healthcare administrators can utilize these insights to foster a robust culture of compliance, ensuring the protection of sensitive patient information and the resilience of healthcare operations against cyber threats. The study suggests that future research explores integrating artificial intelligence, zero-trust architectures, and adaptive risk management frameworks to further enhance cybersecurity strategies and regulatory compliance.

Onion de-topping (i.e., separation of matured leaves from bulbs) is the important post-harvest operation in onion production which conducted after curing process of onion bulbs. In India onion de-topping done mostly manually in farms using sickle, khurpi and knife. Manually onion de-topping of onion bulbs is time consuming and labour-intensive operation. Availability of labours are difficult in peak harvesting season of onion; therefore, farmers may incur financial and crop loss. Mechanical onion de-topping done using onion harvesters during digging operation of onion bulbs. There are many onion de-topping machines are available for onion bulbs with different mechanism. The different onion de-topping machine were studied in terms of their mechanism, construction, working principles, performance and efficiency. The comparison of performance of the machines with manual onion de-topping was studied over the cutting capacity, efficiency, damage percentage, saving of labour cost and time. This paper reviews such onion de-topping harvesters and de-topping machines. It highlights the mechanism used for de-topping in these machines with their performance in terms of de-topping capacity and de-topping efficiency. It also tries to highlight the necessity of requirement of de-topping machines and current status of adoption of such machines by farmers in India. It was observed that number of onion de-topping machines are available though it is difficult to adopt by the farmers specially medium and low land holding farmers because of cost concern. Therefore, it is necessary to develop the machine which should be low cost, efficient and labour saving for such farmers. Using such an onion de-topping machines will help to save their labour cost, operational time, drudgery of labour and increase efficiency of labour. Also adopting such technologies can encourage the farmers to increase the production of such crop.

Road failure in parts of Bayelsa State Nigeria has been constituting nuisance to human and vehicular activities
in the area. This study was designed to investigate the geologic features responsible for road failure in parts of
Ogbia Local Government Area of Bayelsa State, Nigeria. Electrical resistivity method involving 2D imaging of
the failed parts of Otuoke-Onuebum and Imiringi-Emeyal 2 Roads were conducted on four profiles normal to the
strike of the affected parts. The data collected were tomographically inverted and the results predominantly
showed that the failed portions of the roads are characterized with very low resistivities ranging from 0.094 Ωm
to 173 Ωm. These results suggest that the formation underlying the failed portions of the roads are predominantly
clays and peat, loam and mud. These suggest that clay volumetric variation due to variation in moisture content
most likely caused the failure of some parts of the roads. The thicknesses of the clay formations range from 2 m
to 8 m. Also, in the parts underlain by peat, loam and mud, the failure in those segments of the roads is attributed
to the high moisture of the formations, which are easily compress by loads. The thicknesses of the peat, loam and
mud formations range from 3 m to 10 m. It was recommended that excavation of clay and peat, loam and mud deposits be carried out and replaced with less expansive soil like sand on the affected parts of the road to minimize failure

Importance

A wide variety of novel medical diagnostics and devices are determined safe and effective by the US Food and Drug Administration (FDA) each year, but to our knowledge the literature lacks evidence documenting how long it takes to establish new Medicare coverage for these technologies.

Objective

To measure time from FDA authorization to at least nominal Medicare coverage for technologies requiring a new reimbursement pathway.

Design, Setting, and Participants

In this cross-sectional study, public databases were used to associate each technology to billing codes, determine the effective date of each code and Medicare coverage decisions, and stratify by the maturity of the Medicare coverage. At least nominal coverage was defined as achievement of explicit coverage milestones through a national coverage determination, local coverage determinations by Medicare administrative contractors, or by implicit coverage aligned to a new billing code. Characterization by product type (acute treatment, chronic or ongoing treatment, diagnostic assay, and diagnostic device), manufacturer size, and evidence level were assessed for association with coverage achievement. The study included new product applications authorized by the FDA through the premarket approval pathway, the de novo pathway, or with breakthrough designation in the 510(k) pathway from January 1, 2016, to December 31, 2019. Data analysis took place between May 1, 2022, and December 31, 2022.

Main Outcome Measurement

Time from FDA authorization to the first coverage milestone.

Results

Among 281 identified technologies in the total sample, 64 (23%) were deemed novel technologies based on the absence of coverage determinations and/or the use of temporary or miscellaneous billing codes. Twenty-eight of 64 technologies (44%) successfully achieved explicit or implicit coverage following FDA authorization. The median time to at least nominal coverage for the analysis cohort was 5.7 years (90% CI, 4.4-NA years). Analysis of time-to-coverage data highlighted company size (log-rank P<.001) and product type (log-rank P = .01) as significant covariates associated with coverage achievement. No association was observed for technologies with level 1 evidence at FDA authorization and subsequent coverage milestone achievement (log-rank P = .40).

Conclusions and Relevance

In this cross-sectional study of 64 novel technologies, only 28 (44%) achieved coverage milestones over the study timeline. The several-year period observed to establish at least nominal coverage suggests existing coverage processes may affect timely reimbursement of new technologies.

Stop for a moment and consider how our society would react if cancer‐related deaths jumped 25% in one year and 10% in the next. Over a 30% increase in two years. Is there any question that we would declare a national emergency and devote moon‐shot‐level resources into reversing the trend? Task forces would be deployed. Early interventional strategies identified and put into every health care setting in the nation. Cancer is not stigmatized. We treat people who get it as valued members of our society, worthy of help.

Currently, the majority of composite phase change materials (PCM) are only available in solid‐phase environments. Therefore, it is important to prepare composite PCM with photothermal conversion capacity, high thermal conductivity, and stability in both solid and aqueous phase conditions. Herein, a composite PCM with high photothermal conversion storage efficiency (92.6%), high energy storage density (147.6 J g−1), and high thermal conductivity (1.19 W m−1 K) is prepared using poly(acrylamide‐co‐polyacrylic acid) copolymer (PAAAM) as the supporting material, boron nitride as the high thermal conductivity filler, and carboxyl‐rich carbon as the photothermal conversion agent and key bridge. With the help of the characteristics of PAAAM, although the PAAAM chain is swollen not broken, it still maintains cross interconnection with PCM in the water‐phase environment, which has excellent encapsulation performance in both the water/solid phase environment. This provides another option for broadening the application of PCM in aqueous solvent conditions.

In present work, the monotonic and cyclic properties of a novel Al‐Mg‐Zn‐Cu‐Si compositionally complex alloy (CCA) are investigated. Microstructural studies reveal that a eutectic phase and fishbone‐type structures are embedded in the Al‐matrix. The mechanical properties of this CCA obtained under compressive loading are found to be promising. However, low ultimate strength and brittle behavior are seen under tension. The fatigue performance of the alloy in the low‐cycle fatigue (LCF) regime is poor. Microstructural features and fracture surface analysis point to the fact that the presence of brittle intermetallic phases and shrinkage defects are responsible for the poor tensile properties and inferior LCF behavior. Homogenization at 460 and 465 °C for 3 h, 6 h, and 24 h results in spheroidization of all coarse precipitates. However, the heat treatment used is unsuitable to enhance the mechanical properties of this CCA.
