In conclusion, the sociodrama technique improved students' speaking ability.
ENGLISH FOR ACADEMIC PURPOSES LEARNERS' NEEDS ANALYSIS: LANGUAGE DIFFICULTIES ENCOUNTERED BY UNIVERSITY STUDENTS IN ETHIOPIA
Authors: Chemir Sileshi , Kitila Tamene
Published: March 2024

The study sought to uncover the English language barriers that tertiary students faced while studying their academic courses in Ethiopia. The survey involved 421 participants (72 in the pilot research and 349 in the main research). To collect the relevant data, the researchers used a mixed-method technique. The study used probabilistic and purposive sampling techniques to choose samples from the target populations. The findings indicated that students had difficulties (e.g., in academic reading, writing, listening, and speaking) in studying their academic courses in English. The participants also indicated that current English language courses failed to encourage first-year students to improve their academic language competency to continue their studies. This happened due to a lack of thorough examination of learners' needs before creating any language curriculum. As a result, needs analysis should be viewed as the first phase to examine learners’ academic language difficulties and design EAP syllabus that caters academic language requirements of the students both in the target and learning situations.

Authors: Novitasari Novitasari , Wahyuningsih Noverita , Agustina Hiqma Nur
Published: March 2024

Tourist Guiding is a compulsory subject that aims to prepare students to be a prospective Tour Guide (TG) with excellent English mastery, especially speaking. Two-year observation showed that the students have the low ability in speaking skills. They did not speak fluently because they lacked knowledge and vocabulary in tourist guiding. This study was a Classroom Action Research (CAR) which was carried out by implementing Content and Language Integrated Learning (CLIL), as a dual-educational approach that uses additional languages to learn and teach both content and language, in an online Tourist Guiding class. Participated by 28 students, this research followed stages of CAR. Additionally, pre-test and post-test were conducted to investigate students’ different performances before and after CLIL was implemented, while questionnaires were distributed to obtain the data about the students’ voices about CLIL implementation. The findings revealed that the quality of teaching and learning in the Tourist Guiding class improved after the implementation of CLIL. In addition, CLIL could enhance both students’ language skills (especially speaking) and tourist guiding competency. Teachers should both understand the subject content very well and have a very good mastery of English so that CLIL can be implemented successfully.

Second language (L2) occurs when an individual has acquired firstlanguage (L1) and commonly acquired through scientific and naturalways. Second language acquisition generally takes place at younger ageand through formal and nonformal education. Amondus, the participant ofthis study, confirmed that he started to learn and acquire English as hissecond language at his adulthood. Having started to learn English in highschool, he just found it interesting and important during his college time.He found many English terms in his major, nursing. This reason led him toput his extensive effort in learning English. This qualitative descriptivecase study aims at investigating Amondus’ grammatical competence in hissecond language acquisition. Semi-structured and extensive interviewswere used to collect the data before they were analyzed throughtranscription, investigation and classification, analysis, and conclusiondrawing. The results showed that Amondus has possessed and masterednine grammatical morphemes, despite a minor error related to the use ofcopula that was still contextually understandable. Amondus’ oralgrammatical competence related to nine grammatical morphemes wasconsidered effective.
MYTHICAL CAR: METONYMY IN TAYLOR SWIFT'S SONG LYRICS
Authors: Jonathan Irene Sartika Dewi Max
Published: March 2024

Varieties of car-related words reflect how the knowledge involving the vehicle has been stored in cultural society. The repetitive occurrence of phrases about a car in Taylor Swift’s 40 song lyrics raises a question on how such a thing is used in song lyrics to convey meaning.  This article uses Littlemore's (2015) theory to figure out the domain where metonymy is used. To explain the meaning-making process, it adopts Moore’s (2016) notion that to reach metonymy is by analyzing the semiotic property of experiential correlation and descriptions of the semiotic structure which Brandt et. al (2019). Then, a qualitative method suggested by Gravells (2018) is applied to read the interaction among language features in context. The metonymy analysis shows the songs employ the domain of car parts, car types, road areas, driving manners, and street signs as part of car metonymy. The semiotic analysis shows that the car has the mythic meaning of overcoming trouble, private space, taking action, romance, and status so that the meaning is readily grasped by the audiences. Thus, this article enriches the method of researching popular songs where language plays vital parts in the lyrics.

Published: March 2024

Masyarakat adat Bali menganut sistem keluarga patrilineal, atau paternitas, atau lebih dikenal dalam masyarakat adat Bali dengan sebutan kepurusa atau purusa. Sesuai dengan asas-asas umum yang dianut dalam sistem keluarga patrilineal, paling tidak ada tiga asas dasar yang dianut dalam sistem keluarga purusa, antara lain garis keturunan yang dirunut dari garis laki-laki atau ayah, dalam perkawinan seorang perempuan dilepaskan dari hubungan hukumnya dengan keluarga asalnya, akibat perkawinan adalah terbentuknya keluarga inti yang idealnya terdiri dari ayah, ibu dan anak. Sedangkan jika seorang anak laki-laki dari keluarga yang hanya memiliki satu anak laki-laki, akan menikah dengan seorang anak perempuan yang berasal dari keluarga yang hanya memiliki satu anak perempuan, maka akan terjadi perdebatan di antara keluarga tersebut tentang bentuk perkawinan yang akan dipilih. Jika memilih bentuk perkawinan yang biasa, maka pihak keluarga wanita pasti akan keberatan, karena pihak keluarga nantinya akan bercerai. Begitu pula sebaliknya jika memilih bentuk perkawinan nyeburin, maka pihak keluarga pihak laki-laki akan keberatan karena juga akan menimbulkan keadaan pecahnya keturunan, atau biasa disebut ceput atau putung. Oleh karena itu, perempuan dan laki-laki yang merupakan anak tunggal dalam keluarga dapat melakukan perkawinan alternatif di luar kedua bentuk perkawinan di atas. Perkawinan tersebut merupakan perkawinan negara rangkap atau dalam hal ini suami tidak masuk dalam keluarga istri, dan istri tidak masuk dalam keluarga suami. Tentunya akan membawa akibat hukum yang berbeda dari perkawinan biasa atau perkawinan terhadap harta benda perkawinan, kedudukan anak, dan harta warisannya. Untuk menghindari kondisi putung diperlukan terobosan hukum selain bentuk perkawinan biasa dan perkawinan campur, yaitu bentuk perkawinan negen dadua. Di Desa Semarapura Kaja, ada beberapa kasus seperti ini. Untuk itu pendampingan dilakukan dalam rangka peningkatan kesadaran dan pengetahuan tentang hukum hak waris anak dalam perkawinan negen dadua.
Results of determining the geoid height profile and vertical line deviation using GNSS signals reflected from water surface
Authors: Lopatin V.P. , Murzabekov M.M. , Bobrov D.S.
Published: March 2024

The method for determining geoid elevations, based on the use of GNSS signals reflected from water surface, is called bistatic one. Its features are small dimensions and weight of the necessary on-board equipment, and that enables mounting them on a nano-satellite, as well as simultaneously determining several dozen geoid height profiles. It corresponds to the number of visible navigation satellites from among GLONASS, GPS, Galileo, BeiDou. Several space projects using the technology under description were implemented abroad, their analysis has shown the possibility of determining geoid heights with an error of 10–20 cm, as well as sea ice thickness. The authors provide a review of some similar projects, an assessment of the simultaneously determined number of geoid height profiles, and calculation of its elevations and deflection of vertical along a single profile based on primary measurements from the project of CYGNSS. To compensate for various interfering parameters when calculating geoid elevations, the following models were used
Looking for the global minimum of the objective function to determine the pseudoinverse matrix through the search method at equalizing free geodesic networks
Authors: Shevshenko G.G. , Naumova N.A. , Bryn M.Ya.
Published: March 2024

When evaluating the accuracy of equalized free geodetic networks based on the search method of nonlinear programming, a degenerate matrix of unknowns’ normal equations coefficients is formed. It must be pseudoinverse in order to calculate the inverse weight one of the equalized parameters. Performing a mathematical procedure for calculating a pseudoinverse matrix based on the mentioned technology of nonlinear programming at equalizing free geodetic constructions, a situation may arise when the minimization step is incorrectly selected or the approximate values in the desired array of numbers are set roughly. It can lead to finding a local, not a global minimum, as well as to cycling the algorithm. The authors provide the conclusion of the formula and substantiate the conditions on which the elements of the required matrix change, so that the value of the objective function either comes as close as possible to the global minimum, or indicates that it is impossible to achieve it. The correctness of the proposed conditions and the derived formula are confirmed by a test example

Organizational transformation dynamics in hospitals, Crisis lessons
Authors: Zaghmouri Noura
Published: March 2024

Organizational transformation is a multifaceted process that involves
altering an organization’s structure, culture, processes, systems, and
strategies to better adapt to internal and external changes. This
transformative process is characterized by interprofessional
interactions that aim to foster collective dynamics. The likelihood of
organizational transformation failure is considerable, especially in
pluralistic organizations. Our study’s research question centered on the
interactional mechanisms that come into play in the dynamics of
organizational transformations within hospitals during a health crisis,
treating the crisis as a valuable learning opportunity. Following a
six-month period of observation, 28 semi-structured interviews were
conducted between September 2021 and December 2022 with various
professionals from different hierarchical levels and professional
categories in two French hospitals. The research emphasizes the
mechanisms that facilitate the development of a social structure and
social systems in pluralistic organizations and govern individual and
collective actions that regulate the process of organizational
transformation.
Synthetic Identity Fraud a Critical Primary National Security Priority
Authors: Mungai Robert
Published: March 2024

Synthetic identity fraud poses a pervasive threat to national security, presenting formidable challenges to financial systems, government bodies, and businesses. This study scrutinizes the severity of synthetic identity fraud as a paramount national security issue, emphasizing its complex nature, the vulnerabilities it exploits, and its diverse impacts on society. Synthetic identity fraud entails fabricating identities by amalgamating authentic and falsified information, complicating detection for conventional authentication methods. This sophisticated approach empowers fraudsters to establish credit profiles, initiate account openings, and engage in unlawful activities under false pretenses, leading to significant financial losses and eroding trust in institutions. Moreover, synthetic identities are increasingly leveraged in organized crime, terrorism financing, and illicit activities, intensifying the national security threat. The anonymity provided by synthetic identities hampers law enforcement efforts, impeding the identification and apprehension of perpetrators. Tackling synthetic identity fraud necessitates a holistic strategy incorporating technological advancements, regulatory adjustments, and collaborative endeavors among stakeholders. Advanced data analytics, biometric authentication, and machine learning algorithms present promising avenues for early detection and mitigation of synthetic identity schemes. Additionally, robust identity verification protocols and information-sharing frameworks are imperative for reinforcing the resilience of financial ecosystems and protecting national interests. This study underscores the urgency for policymakers, law enforcement agencies, financial institutions, and technology providers to prioritize synthetic identity fraud as a critical national security concern. Through fostering cooperation and implementing proactive measures, stakeholders can strengthen defenses, disrupt criminal networks, and uphold the integrity of economic and societal structures amidst evolving threats.

Authors: Stachura Michał , Wodecka Barbara
Published: March 2024

In the era of increasingly widespread use of electronic communication tools, constant growth of e-commerce turnover is hardly surprising. One of its mechanisms are online auctions whose turnover, on a global scale, is enormous. This paper proposes a stochastic model of the value of subsequent actual bids appearing in the course of a dynamic internet k-th price auction. On this basis, it was possible to determine unconditional joint probability distributions, as well as univariate marginal distributions of successive bids appearing in the course of the auction type under consideration.
On strongly r-ideals on commutative rings and some related graphs
Authors: Alhazmy Khaled , Almahdi Fuad , Bouba El , Tamekkante Mohammed
Published: March 2024

A proper ideal I of a ring R is called an r-ideal if, whenever x, y ? R with
xy ? I, we have x ? I or y ? Z(R) [R. Mohamadian, r-ideals in commutative
rings, Turkish J. Math. 39(5) (2015),733-749]. In this article, we are
interested in a subclass of the class of r-ideals which we call the class of
strongly r-ideals. A proper ideal I of a ring R is called a strongly r-ideal
if, whenever x, y ? R with xy ? I, we have x ? I or y ? Z(I). First, we give
a basic study of this new concept which includes, among others,
characterizations, properties and examples. After that, we use the
introduced concept to characterize rings for which the diameter of the
zero-divisor graph is less than or equal to two, rings for which the
annihilator graph is complete, and rings for which the zero-annihilator
graph is empty.

Authors: Yao Hua , Zhao Ruju , Wang Long , Wei Junchao
Published: March 2024

The (b,c)-inverse and the Bott-Duffin (e,f)-inverse are two classes of
outer inverses, a few characterizations of which have been presented by
certain researchers. In this paper, we give some new characterizations of
(b, c)-inverses and Bott-Duffin (e,f)-inverses. First, we present a number
of ring theoretic characterizations of (b,c)-inverses. Then we characterize
(b, c)-inverses by equations. Finally, we present some characterizations of
Bott-Duffin (e,f)-inverses. More specifically, we use Bott-Duffin (e,f)-
inverses to characterize some classes of rings, such as directly finite
rings, Abelian rings and left min-abel rings.
Commutant hypercyclicity of Hilbert space operators
Authors: Hedayatian Karim , Namegoshayfard Mohammad
Published: March 2024

An operator T on a Hilbert space H is commutant hypercyclic if there is a
vector x in H such that the set {Sx : TS = ST} is dense in H. We prove that
operators on finite dimensional Hilbert space, a rich class of weighted
shift operators, isometries, exponentially isometries and idempotents are
all commutant hypercyclic. Then we discuss on commutant hypercyclicity of 2
? 2 operator matrices. Moreover, for each integer number n ? 2, we give a
commutant hypercyclic nilpotent operator of order n on an infinite
dimensional Hilbert space. Finally, we study commutant transitivity of
operators and give necessary and sufficient conditions for a vector to be a
commutant hypercyclic vector.
On some contractive mappings and a new version of implicit function theorem in topological spaces
Authors: Laha Supriti , Garai Hiranmoy , Petruşel Adrian , Dey Lakshmi
Published: March 2024

Study on existence of fixed points of contraction and contractive (type)
mappings in topological spaces is a challenging task. The main goal of this
article is to deal with this challenging task. To achieve our goal, we
define two new contractive type mappings, namely, h-A-contractive and
h-A1-contractive mappings on a topological space X, where h : X ? X ? R+ is
a function and A, A1 are two collections of implicit functions. Then, we
obtain some fixed point results concerning such contractive type mappings.
Finally, as an application of one of the above mentioned fixed point
results, we obtain a newer version of the implicit function theorem in
topological spaces.

On the Evaluation Scheme for Large Scale Innovation Competition
Authors: B* Zhao
Published: March 2024

Large-scale innovation contests are becoming increasingly popular globally, with many innovators and enterprises actively participating. Work allocation optimization and fair judging are two significant concerns in innovation contests. This academic paper aims to recommend an optimized "cross-assignment" program by leveraging the optimal objective function method to improve the comparability of scores given by various judges. We conducted data-based descriptive statistical analysis and concluded that the two-stage and weighted evaluation schemes are more beneficial than the traditional judging scheme. Nonetheless, there are still some shortcomings that require addressing. To enhance fairness, we propose an improved twostage evaluation scheme. In the first stage, we normalize the scores with a normal distribution. In the second stage of the process, we implement a system utilizing the Borda sorting technique to categorize submissions into five distinct groups for judges to evaluate based on their perceptions. We also detail a method for weighting tied scores to determine the final rankings. Testing indicates that this approach yields a Normalized Discounted Cumulative Gain (NDCG) of 0.8667, implying greater fairness and precision in the assessment of submissions.

On March 11, 2020, the world health organization World Health Organization (WHO) declared COVID-19 as a Global Pandemic, and on April 13, 2020, the Government of Indonesia issued a Presidential Decree of the Republic of Indonesia Number 12 of 2020 concerning the Determination of Non-Natural Disasters for the Spread of Corona Virus Disease 2019 (COVID-19) as National Disasters. People infected with the Covid-19 outbreak every day continue to increase, as well as the number of deaths due to the Covid-19 outbreak continues to grow. The Central Government and the Dareah Government issued policies to prevent and overcome the spread of the COVID-19 outbreak, namely by implementing Large-Scale Social Restrictions (PSBB) and the Implementation of Community Activity Restrictions (PPKM). With the existence of PSBB and PPKM by the Government, several sectors, especially the accommodation provision sector, tourism business, food and beverage business, real estate, and construction, have experienced a direct impact as a result of the Covid-19 pandemic and the existence of PSBB and PPKM. The tourism sector, especially hotels, has experienced a decrease in income due to the lack of guests staying, forcing employers to lay off their workers/workers without providing wages to reduce expenses and save company finances. This thesis research analyzes the impact arising from workers/workers being laid off without being given wages and legal considerations on the decision of the Industrial Relations Court at the Central Jakarta District Court with case number: 398 / Pdt. Sus PHI / 2021 / PN. JKT. PST. The purpose of this decision analysis is to find out the Request for Termination of Employment (PHK) by Workers / Workers because they were laid off for more than three months without wages based on Law Number 11 of 2020 concerning Job Creation.
MAPPING EFFECTIVE MULTI REGIONAL TREATIES ON BLUE ECONOMY
Authors: Meliala Aurora
Published: March 2024

Indonesia as an archipelago with more than 17,000 islands, has a unique geographical and great potential as a maritime country. Primarily, Indonesia's efforts to realize sustainable fisheries is by promoting and implementing the ASEAN Blue Economy Framework as one of the country's economic deliverables. Furthermore, among the various measures and policies that have been set by the Indonesian government, measurable fishing is a breakthrough in fostering the marine and fisheries sector and specifically regulating the blue economy. In the context of international trade, Indonesia has also made several efforts including the implementation of measured quotas and sustainable certification. Quotas and certification are two ways to resolve the issue of legality. Even so, illegal fishing is still a major challenge in the framework of sustainability. One of the main goals that Indonesia can set to ensure its involvement and leadership in ASEAN maritime connectivity is the construction of a national sustainable fisheries system, that is specifically related to the implementation strategy of sustainability commitment, that serves as a pioneer/pioneer of similar systems in the regional arena.

Pembangunan infrastruktur seperti konstruksi jalan tol merupakan salah satu tujuan dari Kementerian Pekerjaan Umum dan Perumahan Rakyat, dimana tujuan dan manfaat dalam penyelengaraan pembangunan jalan tol merupakan salah satu wujud untuk menciptakan perkembangan pertumbuhan ekonomi dan sosial. Jalan Tol Trans Sumatera adalah jaringan Jalan Tol sepanjang 2.818 Km yang merupakan terpanjang di Indonesia untuk saat ini. Pembangunan Jalan Tol yang menghubungkan kota-kota mulai dari Lampung hingga Aceh. Kehadiran Pembangunan Ruas Jalan Tol Kuala Tanjung – Inderapura sepanjang 18,05 Km yang terletak di Kabupaten Batubara Provinsi Sumatera Utara, merupakan koneksi menghubungkan Pelabuhan Internasional Kuala Tanjung dan Industrial Estate, sehingga akses pendistribusian logistik dari Kota Medan ke kawasan industri sekitarnya hingga ke pelabuhan menjadi semakin lebih mudah dan cepat. Dalam konstruksi pembangunan Jalan Tol di Kuala Tanjung – Inderapura memiliki tipikal desain yang hampir sama dengan konstruksi Jalan Tol lainnya, seperti perkerasan jalan menggunakan Rigid Pavement, Bangunan Struktur Jembatan, Struktur Overpass dan Bangunan Crossing Air (Box Culvert). Setelah ada surat permohonan perubahan konstruksi oleh dinas terkait, tim pelaksanaan konstruksi melakukan pengecekkan bersama oleh 3 (tiga) pihak yaitu Owner, Konsultan Supervisi dan Kontraktor Pelaksana, terdapat Aliran Sungai Sei Sipare-pare beserta Tanggul Buatan dan Tanggul Alami yang melintasi Trase Jalan Tol yang akan dibangun. Dari desain awal konstruksi yang akan dibangun sebagai oprit dari jembatan pendekat sungai adalah Timbunan Tinggi dengan tipe perkerasan Rigid Pavement, dan kemudian terjadi penolakan desain konstruksi dari pihak Dinas BBWS dan Bupati setempat terkait timbunan pendekat sungai Sei Sipare-pare. Dikarenakan di Sungai Sei Sipare-pare memiliki Tanggul Buatan dan Tanggul Alami yang merupakan Garis Sempadan Sungai yang tidak bisa sebagai ruang penyalur banjir, sehingga perlu dilalukan reviu ulang desain dengan metode matriks pemilihan penggantian jenis konstruksi lainnya.
Determination of local stiffness for the joint of tunnel lining in the simulation
Authors: Xiao Z. , Wang J. , Wang J. , Zhou H.
Published: March 2024

In the numerical simulation of shield tunnel, the treatment of joints will greatly affect the accuracy of numerical analysis. Because the stiffness of the joint is lower than the stiffness of segments, the local weakening method is adopted in this paper , which can simulate the stiffness heterogeneity in the transverse and longitudinal directions of the tunnel lining. In the method, lower local stiffness is used for the joint which is the connection between segments and rings of lining, while the stiffness of segments keeps to be unchanged. The local stiffness of the joint, which is represented by the elastic modulus of the joint in the simulation, is the key point. To verify the validity of the method, multiple full-scale experiment [11-14] objects are analyzed and the simulation results are compared to the experiment data. Then the empirical formula of elastic modulus of the weakening joint is proposed by analyzing the three-ring lining in a full-scale experiment under different assemblages. Further, the empirical formula of elastic modulus for the joint is expanded to the large-diameter tunnel and super-large-diameter tunnel. It provides a good reference for the determination of elastic modulus of the joint in the simulation of shield tunnel.

The Cat 16M Grader is a heavy equipment that is widely used to support mining operations. The development of this heavy equipment is required to use biodesel fuel (B30). The problem with B30 fuel is oxidation which results in the formation of sediment and can cause filter clogging. Filter clogging can affect engine power and filter replacement time. From these problems, the researcher proposed to modify the number of sediment separator core holes to reduce the filter clogging rate on the Cat 16M grader. Modified number of sediment separator core holes are 40, 20 and 10 holes with 8 mm hole dimension. Data was collected experimentally by implementing the modified sediment separator core on a Cat 16M grader for 250 hours of operation. The research resulted in the number of sediment separator core holes 10 at 250 hours of operation producing the highest sediment volume of 92 ml, the filter with the lowest clogging rate and the lowest fuel pressure difference. In addition, using the number of sediment separator cores 10 at 250 hours of operation produces the highest engine power, the highest filter clogging efficiency and has a high economic value.
