Authors: Siregar Muhammad Risky Qamad , Sarifah Jupriah , Simbolon Ronal H T
Published: December 2024

Construction projects are of course carried out in accordance with the implementation plan which is prepared based on the letter of agreement, general contract conditions, special contract conditions and technical specifications. In this plan, it is determined when the project must start and when the project must be finished. In every construction project, of course all parties involved want the project to be completed on time as previously determined. However, in reality, projects have their own problems and obstacles. One of the problems that really affects project performance in terms of time, quality and cost is the problem of project delays. In this study, a case study was carried out regarding the identification and analysis of factors causing delays in work on the Wiego Warehouse Building Construction project so that from the results of the analysis of factors causing delays, dominant factors and responses to handling them can be obtained. The Wiego Warehouse building is located on Jalan Letda Sujono, Medan and was built by contractor PT. Mitra Mandiri Asset Indo. This became the basis for conducting this research. The aim of this research is to determine the causes/risk factors that have a high level (dominant) and risk management responses that have a high level, in order to improve contractor performance. The research used is descriptive, using a questionnaire as a research instrument. Study of factors causing delays using the risk frequency scale, risk impact scale, and risk analysis matrix. The research results show that risk events are included in the classification of causal factors/high risk (high risk), which are significant for the problem of delays in building project implementation and the handling response to risk events that have a high ratio level. The dominant factor factor causing delays has a Severity index value of 61% - 80% and a risk level value of 16 (sixteen). For handling, there are several handling actions for dominant risks. Handling is carried out to minimize factors that cause delays and avoid sanctions or fines.
Juridical Analysis of IPR Decision No. 438K/Pdt.Sus-Hki/2018 Concerning the "Lexus" Brand Dispute Between Marzuki Tan and Toyota Jidosha Kabushiki
Authors: Michaela Michaela
Published: December 2024

The "LEXUS" brand dispute between Marzuki Tan and Toyota Jidosha Kabushiki is one of the important cases in intellectual property law in Indonesia. The Commercial Court at the Central Jakarta District Court and the Supreme Court assessed that the registration of the trademark "LEXUS" by the Defendant was carried out in bad faith. In deciding this case, both courts considered various legal elements, including the substantial similarities between the mark registered by the Defendant and the well-known mark owned by the Plaintiff. This similarity, including visual, phonetic and conceptual aspects, is considered to have the potential to mislead consumers and harm legitimate brand owners. The plaintiff successfully demonstrated that its "LEXUS" mark is a well-known brand with a global reputation, which is widely promoted through various media. The Court concluded that the Defendant acted with the intention to take advantage of the Plaintiff's brand reputation, which constitutes a violation of the good faith principle in trademark registration. Supreme Court decision in cassation no. 438 K/Pdt.Sus-HKI/2018 strengthens the Commercial Court's decision, emphasizing the protection of well-known marks from dishonest registration. This case not only provides legal protection for brand owners, but also establishes an important legal precedent regarding good faith in brand registration in Indonesia. Thus, this decision strengthens the well-known brand protection system, prevents attempts at imitation, and increases legal certainty in the protection of intellectual property in Indonesia.

Authors: S.T. Kansil Christine , Fadloli Muhammad
Published: December 2024

Taxes are a source of state revenue collected from the public based on legislation and used to finance state interests, including the execution of tasks for the public good. The relationship between taxes and development in Indonesia is very close, as infrastructure development can be realized thanks to tax revenue. The taxes paid by the community are used to finance government expenditures, including public projects such as road widening and asphalting in rural and urban areas. This development aims to ensure that the community has adequate transportation access, so that daily activities run smoothly. Taxes serve as an important source of government funding to finance various activities, including development. Therefore, taxes play a key role in the administration of the state.

Published: December 2024

The Community Service Program (KKN) in Sungai Ular Village, Secanggang District, Langkat Regency, aims to develop community potential through three main focuses: religious moderation, empowerment of digital technology-based MSMEs, and stunting prevention. Through a Participatory Action Research (PAR) approach, KKN activities involve the community directly in the process of social and economic improvement. The religious moderation program has succeeded in deepening understanding of religion, increasing tolerance, and strengthening relations between religious communities through activities such as Maghrib Koran Recitation, Wirit for Mothers, and Wirit for Youth. Empowerment of MSMEs, especially in the palm sugar sector, is carried out by providing digital marketing training and promotional support through e-commerce platforms to expand markets and increase income. The stunting prevention program provides education to the public regarding the importance of balanced nutrition, reproductive health, and the impact of early marriage on stunting. The results of implementing this KKN show increased community awareness and sustainability in local economic development and public health, which has the potential to reduce the prevalence of stunting and improve the quality of life in Sungai Ular Village.

Alternate Level of Care Patients in Canada: a Scoping Review
Authors: Maisonnave Mariano , Rajabi Enayat , Taghavi Majid , VanBerkel Peter
Published: December 2024

Background
There has been increasing concern over the growing number of Alternate Level of Care (ALC) patients in Canada who must wait in hospitals for more appropriate settings to meet their needs. ALC patients may have to stay in hospitals for days or months due to a lack of available long-term care capacity, home care services, or other discharge routes.
Method
We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) method to review 35 papers on the topic of ALC patients and delayed discharge in Canada from different perspectives, including (1) the shared characteristics of ALC patients in Canada; and (2) their impact on the Canadian healthcare system, medical staff, and family members. Furthermore, from the reviewed works, (3) we also investigate the factors that impact the length of the hospital stays. Results
We highlighted how the ALC problem is increasing healthcare costs, disrupting services, increasing waiting times, and compromising access to valuable resources. We found evidence suggesting that this far-reaching crisis affects the patients, their families, and the medical personnel. We discovered several logistical issues (such as access to long-term care) affecting the patient’s hospital length of stay.
Conclusions
Our research contributes to understanding this intricate problem, and helps policymakers take steps to tackle this challenge to ensure timely and appropriate care for all patients.

Authors: Mah Jasmine , Kanagalingam Tharsan , Best Sarah , Elhayek Sallie , Thain Jenny , Morais José , Lamarre Marianne , Bhangu Jaspreet , J. Borrie Michael , Sirisegaram Luxey
Published: December 2024

Background
There is a projected and growing gap of geriatricians in Canada. Geriatricians play a crucial role in addressing the health needs of older adults. We aimed to understand the factors that influence the choice of first-practice location for new geriatricians in the context of an aging Canadian population.
Methods
We distributed an online survey to geriatric medicine subspecialty residents and recently licensed geriatricians in Canada. The survey was developed through expert opinions, career planning sessions, and a literature review. There were nine survey sections: general characteristics, location determinants, practice determinants, colleague determinants, support and space, non-clinical opportunities, income models, lifestyle factors, and recruitment determinants. The data were analyzed descriptively.
Results
A total of 61 respondents (51 English, 10 French) completed the survey. The respondents were new practicing geriatricians (37) and geriatric medicine residents (24). Most planned to practice in Ontario (26.2%) or Quebec (27.9%), and 75.4% were women. Flexibility in work-life balance (95.1%), collegiality (93.4%) and reasonable call schedules (93.4%) were the most important factors influencing first practice location. Income did not rank among the highest priorities for choosing the first practice location relative to other factors but was mentioned in open-ended responses to recruitment questions.
Conclusions
This is the first survey identifying the determinants of first practice location in geriatric medicine in Canada. Work-life balance and collegial support are a priority for new geriatricians and may be the strongest incentives a program can provide. For recruitment, income incentives may be beneficial to building new specialized geriatric services. Future research will examine determinants of first practice location among Care of the Elderly clinicians.
Erwartungen, Bringschuldpflichten und Wissenskommunikation
Authors: Hellmann Gunther
Published: December 2024

Seit dem russischen Krieg in der Ukraine und mit der allseitigen Präsenz von IB-Wissenschaftler*innen in den Medien hat sich zwar die ‚Relevanz'-Klage erledigt, nicht aber der Bedarf an fachinterner Selbstvergewisserung über den Standort als Wissenschaft. In diesem Beitrag diskutiere ich die ‚Bringschuldpflichten‘ der IB, insbesondere ein Selbstverständnis, das einerseits die Erwartungen ernst nimmt, die Gesellschaft und Politik formulieren, andererseits aber auch anerkennt, dass bei sozialwissenschaftlicher Forschung ein spezifisches Rollenverständnis von Wissenschaft(lichkeit) respektiert werden sollte, insbesondere die Aufgabe, Übersichtlichkeit in unübersichtlichen Problemfeldern zu befördern. Ferner skizziere ich die praktischen Konsequenzen eines anti-repräsentationalistischen Verständnisses der Wissensproduktion und –kommunikation im Binnen- wie im Außenverhältnis, einschließlich des Verzichts auf universelle Wahrheitsansprüche. Wie unangemessen letztere sind, zeigt das Beispiel der öffentlichen Diskussion über die Möglichkeit eines Nuklearwaffeneinsatzes im russischen Krieg. Dieses Beispiel dient auch der Illustrierung von Herausforderungen, vor denen die IB als Fach stehen, wenn sie vor dem Hintergrund eines imaginären „Standes der Wissenschaft“ Stellung beziehen soll.
Whose war is it (or not)? Who speaks for whom? Discourses and Absences in the War on Ukraine
Authors: Tripathi Siddharth
Published: December 2024

The war on Ukraine and the bifurcated discourses (political and academic) around it across different geographies are just one of the myriad manifestations of hierarchies, postcolonial continuities and contestations guiding global politics. The general political support for Ukraine and foundational norms of the international order such as non-intervention and sovereignty were broadly uncontested across the global North and the global South, the frames for the analysis, interpretation and implications vary drastically. In this paper, I examine the coloniality of frames and discourses used in the North/West to describe the war and the racialised hierarchies that exist within them. Specifically, I explore the politics of knowledge production regarding who sets the agenda and where, whose voices are prioritized and who is marginalised. By focusing on some perspectives from the global South, this paper foregrounds the responses of global South countries which have been marginalised in the war on Ukraine.
Bio-Mitigation of Carbon Dioxide Using Microalgae Cultivated in Tubular-Photobioreactor
Authors: Aidan Al-Hussieny Ahmed
Published: December 2024

Bio-mitigation lowers greenhouse gas technology dioxide levels. Chlorella sorokiniana during a 24-day laboratory study period were evaluated at five distinct CO2 concentrations: 5, 10, 15, 20, and 25 L/min while being cultivated in nitrogen, phosphorus, and potassium (NPK) growth media. The CO2 removal rate employed was 92.94% including proteins, lipids, phenols, flavones, glycosyrosiates, anthocyanins, and carotenoids, whereas the greatest level of gas was 25 L/min or 6000 mg/L. The biomass’s greatest proportion of proteins and lipids for the highest rate of gas (25 L/min) reached 47.08%, respectively, and 34.05% relative to the control 31.32% and 20.35%, respectively, as measured by its 0.102 nm difference from the control, and through the efficiency of the isolate of Chl. sorokiniana. It was tested by reducing the highest CO2 levels of 25 L/min within a 200 L photo bioreactor design. with a period of 24 days in the laboratory’s natural environment. After harvesting the algal reactor cultivation of 200 L, the biomass weight reached 900 g/L. This means that for every 1 g of algae biomass, 1.7 g of CO2 is consumed.

Published: December 2024

The study was carried out during three successive growing seasons from 2015 to 2017 at Salamiyya Research Center, Syria. That was to study the alfalfa crop water requirement and how we can improve its water crop productivity. Three treatments: drip method (A1), sprinkler method (A2), and surface one (A3) were designed and implemented using complete randomized block design (CRBD) with three replicators as well as surface irrigation treatment (A4) as the area’s farmer does. All these programs: WEAP21 (SPAW and MABIA), NewLoc-Clim1.10, and ET0Calc had been used. The simulation results for SPAW and MABIA programs after calibration were approximately identical. Alfalfa response coefficient reached 0.78 in the modern irrigation methods and 0.91 in the surface irrigation method in this type of soil. The water saving has been reached at 29% for drip irrigation and 22% for sprinkler irrigation compared with the surface irrigation method. There were tangible significant differences at the Water Use Efficiency (WUE), whereas treatment A1 excelled all the rest treatments, and the order of this excellence was as follows: A1 > A2 > A3 > A4. Finally, the integrated program (MABIA) and other programs can be considered very modern and sophisticated tools, making the water expert save time, effort, and costs in addition to obtaining very accurate results.
Computational Methods for Personalized Targeted Therapy in Uterine Leiomyosacoma
Authors: Shakeel Hoosdally
Published: December 2024

Uterine leiomyosarcoma (ULMS) is an uncommon gynecological cancer, and treatments such as surgical debulking, chemotherapy, and radiotherapy have had limited results. This investigation study is about a scenario of a 53- year-old woman, whereby conventional protocol through combining doxetatacel, gemcitabine, pazopanib, pemetrexed, and doxorubicin with surgery and radiation did not avoid metastasis, resulting in the death of the patient. A strategy of personalized tumor therapy was used. Through the recommendation of a ctdna (circulating tumor DNA) next-generation sequencing (NGS) using blood sample, the mutated tp53 c338y was identified. A built homology of the mutated TP 53 proteins with a drug library of 1133 FDA approved drugs can be used in repurposing as part of the therapy regimen. Virtual drug screening using molecular docking was performed with PyRx 0.8 and dockey software. The top 10 drugs were found to bind to the target genes. Three from the top 10 were further refined with AutoDock 4.2.6. The identification of small molecules could essentially be utilized for personalized leiomyosarcoma, specially with patients carrying the tp53 mutations. This concept of personalized tumor therapy could be effective not only for uterine leiomyosarcoma but for other tumors as well.

Published: December 2024

This paper presents the basic features of mortality analysis using period life tables. While life table construction is outside the aims of this paper, the elements analyzed are the life expectancy at birth, probabilities of death, death, and survival curves. Therefore, an attempt is made here to present an overall picture of the study of the mortality phenomenon. However, due to the multitude of different approaches, this picture will be short and comprehensive, failing to cover all aspects of the phenomenon and the entire literature in a limited space. All modes of analysis will be accompanied by corresponding examples, which will assist the researcher in a more complete understanding of the analytical methods presented. The epilogue summarizes the analytical scheme and briefly mentions new research efforts that may occur in the future.

Freshwater Aquaculture, Fisheries and Limnology in Colombia: Review and Personal Data
Authors: Mikkola Heimo
Published: December 2024

This chapter reviews, partly on personal data, the history of inland aquaculture, fishing and limnology in Colombia. Since the 1970s the country has been aware of the importance of aquaculture in the future of its economy due to the constant increase of a population that is increasingly in need of protein of animal origin. In 1972, a joint project between the Government of Colombia and the Food and Agriculture Organization of the United Nations was approved and began to function, aimed at studying inland fishing and developing aquaculture in the county. The work of the project is described, as are the fish culture and fisheries research activities starting with the situation in the 1970s but comparing it with recent findings. A list of the main capture and culture fish species is given. Colombian fishing production has had great variations, but inland water fishing has always been higher than marine. For instance, in 1972 total fish catch was 104, 390 tons and 79% of the total originated from inland waters. Our standing stock estimates indicated clearly that the fish productivity on Magdalena floodplain was relatively low. Comparable habitats in Zambia, Africa, had much higher standing crops. In the Magdalena floodplain, standing crop was 251 kg/ha during the rising water phase in August, as compared with 879 kg/ha from the Kafue floodplain at low water and 2682 kg/ha at the high water. Future development prospects of inland fisheries and aquaculture are discussed and a mention is made of ornamental fish cultivation and trade as well as the present situation of the sport fishing and civil war conflict.
Corporate Governance in Family Businesses
Authors: Fayyaz Anjum , Anjum Zainab
Published: December 2024

Corporate governance in family businesses is gaining popularity as a field of study among both family business and corporate governance researchers and scholars. However, there is a lack of consensus and a lack of understanding of the definition and role of corporate governance in family businesses. This chapter addresses this gap in four ways. First, it reviews the existing literature to construct a holistic and integrated definition of corporate governance in family businesses. This definition includes both the task-oriented and scope-oriented definitions of corporate governance in family businesses, including shareholders, multiple stakeholders, and control dimensions. Second, this chapter uses case study methodology to identify significant gaps in research, such as stakeholders, not stockholders, conflicts of interest due to succession and priority, lack of professionalization, and passive shareholders. Third, this chapter makes logical recommendations for future research, including all stakeholders, continuity research, professionalization, board of directors (BOD) composition and diversification, passive shareholders, and effects of varied institutional contexts. These recommendations will help scholars of corporate governance and family businesses adopt a context-specific approach to corporate governance in family businesses. If we look at the context of the study, the two Pakistani companies were selected by the authors based on convenient sampling. The authors have been working as consultants in these companies, and the study has its own limitations, biases, and benefits due to the deeper association of the authors with the selected companies. These companies have three major businesses in each of them. One company has a manufacturing setup of adhesives, foam, and apparel, whereas the other company has two major manufacturing units, including electronics and pharmaceuticals, and the third one is a resort. All these businesses operate out of Lahore, Punjab, Pakistan. Fourth, this chapter proposes a contextual framework to clarify the definition, complexity, and understanding of corporate governance in family businesses by adding new variables such as trust, transparency, value, respect, and willingness to do succession by the founder members and the leading generations.

In this paper, we report on a sensor network for structural health monitoring (SHM) of Type IV composite overwrapped pressure vessels (COPVs) designed for hydrogen storage. The sensor network consists of three different SHM sensing technologies: ultrasonic guided waves (GW), acoustic emission (AE) testing, and distributed fiber optic sensors (DFOS). We present an experimental setup for a lifetime test, where a COPV is subjected to cyclic loading. Data from all sensors are collected and centrally evaluated. The COPV failed after approximately 60,000 load cycles, and the sensor network proved capable of detecting and localizing the damage even before the failure of the COPV. This multi-sensor approach offers significantly more channels of information and could therefore enable a transition from costly and time-consuming periodic inspections to more efficient and modern predictive maintenance strategies, including artificial intelligence (AI)-based evaluation. This not only has a positive effect on operational costs but enhances safety through the early identification of critical conditions in the overall system in real-time. In the future, we aim to integrate the measurement setup into a hydrogen refueling station with the data stream implemented into a digital signal processing chain and a digital twin.
Knowledge Transfer between Oscillators and Real Vibrating Structures to Enrich Dynamic Monitoring Datasets
Authors:   Politecnico di Torino, Cavanni Valeria ,   Politecnico di Torino, Ceravolo Rosario ,   Politecnico di Torino, Miraglia Gaetano
Published: December 2024

Transfer learning (TL) techniques can be exploited in engineering structures to overcome the main limit of the

data-driven approaches for dynamic monitoring, namely the lack of a labelled dataset for some structural

configuration of the monitored systems. A variety of methods can be implemented, but those that enable

heterogeneous TL based on domain adaptation have proven to be particularly useful, as they allow knowledge to

be transferred within a population composed of a wider range of structures. Among them, the kernelized Bayesian

transfer learning (KBTL) can be used to improve the knowledge of a less monitored structure exploiting the

knowledge of a more monitored one. In this paper the KBTL is assumed to transfer information from an oscillator

to a spatial frame and then from a laboratory masonry oscillator to an historical bell tower for which a limited set

of dynamic monitoring observations is available.

Published: December 2024

The expected growth of new offshore wind turbine installations necessitates

effective Operation and Maintenance strategies to ensure wind farm reliability. Key to these strategies is optimizing operational uptime for Crew Transfer Vessels (CTVs), which transport technicians to wind farms. However, CTV operations are often cancelled due to harsh weather, creating a critical need for continuous operation during favourable conditions. This demand frequently leads to corrective maintenance of the CTV, which increases the risk of unexpected breakdowns. Transitioning to condition-based maintenance can help mitigate the risk of unexpected breakdowns while ensuring uninterrupted operation.

At the core of this is the technology of Structural Health Monitoring (SHM),

aiming to identify deviations from a normal, undamaged condition of the structure. Essentially, if the structural characteristics remain constant, deviations from this normal condition can be interpreted as structural damage. However, under time-variant operating conditions, the structural characteristics vary, complicating the identification of deviations caused by damages.

This study addresses this challenge by separating the operation of a CTV into

operational modes, each defined by unique structural load conditions. Then, a Random Forest model using easily accessible input features is implemented to identify the active mode during operation. Hence, deviations from the normal condition of the specific mode can be identified. While the Random Forest model demonstrates high accuracy in this regard, future potential limitations emerged, prompting considerations for future improvements.
Advancements in Arabic Sign Language Recognition: A Method based on Deep Learning to Improve Communication Access
Authors: Bilal Zaid Saad
Published: December 2024

This research anticipates the issue of real-time sign language recognition as a means of facilitating the daily communication of the hearing-impaired persons. Improvement in the rate of real time sign language recognition will help in boosting interaction in the society and access to services for the hearing-impaired persons. This paper outlines a step-by-step guide on fine tuning an object detection model for the AASL using the SSD architecture. The AASL dataset which includes total of 7,857 samples of more than 200 patients are first preprocessed where the images are scaled, normalized, and augmented. In SSD model, the base of the network is the VGG16 network and few extra layers for feature extraction and for auxiliary and prediction of objects are added. Particularly in object detection, Intersection over Union (IoU), and mean Average Precision (mAP) are used in addition to the confusion matrix metrics comprising accuracy, precision, recall, and F1-score. The proposed model provides good recognition accuracy of 98 percent. This feature checks its capability of real-time identification of sign languages and shows 25% efficiency. The efficiency of the proposed method is explained when comparing the results of the modified VGG16-based SSD with other methodologies. As for the improvement of communication for the hearing-impaired individuals, the present work demonstrates that the deep learning methods can be significantly effective; however, suggesting that more research efforts should be directed to real-time solutions and that the datasets should be expanded.

Published: December 2024

The Recommendation System is one of the latest application tools developed through Deep Learning research activities under the Machine Learning technical domain. The application might have recognized an idea for establishing a user-item relationship on consumables with guidance from the user’s historical purchasing transaction data to achieve future demand predictions. Researchers had been able to bring out memory-based concepts at the beginning supplemented with model-based tools for further refinements with time. Incidentally, the significance of RS was well accepted by business entities, hence personalized services had been initiated to reduce user agony to search out the desired item. In recent years marked improvement was observed with the development of hybrid RS ornamented with the addition of Transformers in the model. The success of the introduction of Next Basket Recommendation relied on the capacity to analyze the user sequential change pattern in purchasing behavior.

The Internet of Things (IoT) is now used by people, homes, transportation, hospitals, and more, and the data collected from IoT devices is more diverse and vaster. Online data trading or sharing systems are evolving to use this data to create new value or utilize it for financial gain. Traditional online data trading systems rely on trusted third parties to ensure fair trading. However, these centralized trading systems suffer from various problems such as single point of failure and data leakage. Therefore, in this paper, we propose a blockchain-based fair data trading model that does not rely on a fixed trust factor and supports bilateral access rights management. The proposed model is designed in a hybrid way that combines on-chain and off-chain processes to minimize the storage space and performance limitations of the blockchain. Instead of relying on a fixed trust factor such as a trusted third party, we randomly select arbiter nodes during each data trading process, which provides higher decentralization than existing approaches. It also provides data confidentiality by ensuring bilateral access control and provides security in the dispute resolution process. Finally, smart contracts in the proposed model perform only simple computations, resulting in lower overhead and higher efficiency than existing models.

The study examined the current implementation of the research management system at the National University of Laos. The population comprised 1,302 faculty members across 13 affiliated faculties, with a sample size of 306 determined using Yamane’s formula (1973). A five-point Likert scale questionnaire, validated by five experts in research and management, served as the primary data collection instrument, yielding a reliability coefficient of 0.97. Stratified sampling was employed to gather the data, which were analyzed using descriptive statistics, including frequency, percentage, mean, and standard deviation. Additionally, content analysis was used for the qualitative component. The findings revealed that the overall input of the system was rated at an Agree level, although limited budget allocation and the absence of research manuals were identified as critical issues. The research process was frequently practiced, but deficiencies in applying research findings were noted. The output was similarly rated at an Agree level, though there was limited utilization of research outcomes. While generally positive, feedback mechanisms lacked sufficient depth in reflection and improvement. To optimize research management, it is recommended that managers focus on securing financial resources, providing comprehensive research guides, enhancing the utilization of research outputs, and strengthening feedback processes

Streams in the Atlantic Forest of Brazil are home to a great diversity of endemic freshwater fishes, but some fish groups are still poorly known. In the last 22 years, our field inventories have recorded some species of the mountain catfish genus Trichomycterus that are endemic to the Rio Itabapoana Basin, among which two were not still described. Herein, we provide formal descriptions for these two species. One of these species is a member of the NMM-clade of the subgenus Cryptocambeva and the other one belongs to the beta-clade of the subgenus Psammocambeva. Both species are diagnosed by an exclusive combination of character states of the external morphology and osteology. This study indicates that the number of endemic trichomycterine species in the Rio Itabapoana Basin, presently five, is larger than in any other small coastal river basin of the Atlantic Forest. A key for identification of species of Trichomycterus from this basin is provided. We discuss two factors that may be responsible for the relatively high concentration of trichomycterines in this basin: streams draining separate mountain ranges or possible past connections with two neighbouring larger basins, the Rio Doce and the Rio Paraíba do Sul basins.

Los conectores de la «Primera» y «Cuarta Partida» de Alfonso X El Sabio
Authors: Mora García Javier
Published: December 2024

Los manuscritos de las obras de Alfonso X siguen siendo objeto de estudio para los investigadores. Aunque se han realizado numerosos trabajos de muy diversa temática (Faulhaber, 1985; Fradejas, 2017; Prádanos Fernández, 2023; Rodríguez Porto, 2023; Mora, en prensa, entre otros), aún quedan materias que explorar, como la que nos ocupa en este artículo: los marcadores del discurso. Estos conectores textuales han recibido una gran atención por parte de los historiadores de la lengua, sobre todo en los estudios de diacronía, y se establece a Alfonso X como una de las figuras fundamentales para el desarrollo de estas unidades. Por este motivo, en ese trabajo se realizará un análisis estadístico de los marcadores del discurso localizados en la Primera y en la Cuarta Partida para, posteriormente, explicar las funciones que tienen en los contextos examinados y las posibles causas de estos resultados.

Published: December 2024

The application of the behavioristic model in technology-based Islamic Religious Education (PAI) learning focuses on changing student behavior through appropriate stimulation. Behaviorism as a learning theory emphasizes that human behavior can be manipulated and learned through interaction with the environment. In the PAI context, the use of technology functions as a tool to strengthen the learning process, increase understanding, and shape the character of students. Through the literature review method, this article discusses the contribution of behaviorist theory in creating effective learning designs, as well as the importance of technology integration to achieve more holistic educational goals. The results show that the behavioristic learning model can increase students' motivation and responses, as well as facilitate positive attitude changes.

This research is motivated by the low utilization of the History Department's reading room by History Department students at Universitas Negeri Padang. This reading room is a learning facility aimed at supporting the academic process within the history department. This study aims to determine the benefits of the History Department's reading room for History Department students at Universitas Negeri Padang. This research is a descriptive qualitative study. The subjects of this study were obtained through interviews with history students from the 2015, 2016, and 2017 cohorts at Universitas Negeri Padang. The data analysis technique used was interactive analysis, consisting of data collection, data reduction, data display, and data verification. The research findings indicate that, out of the 45 students who participated in this study, many reported numerous benefits of using the History Department's reading room, such as facilitating the completion of assignments and increasing class participation due to frequent reading and borrowing books from the reading room. However, some students did not utilize the reading room due to reasons such as an incomplete book collection, inadequate facilities, particularly the air conditioning, and unfriendly library staff.
