Authors: Kurniawan Nyoman Rama Aditya , Darwinata Agus Eka , Ekawati Ni Putu
Published: December 2023

Colorectal tumour location is important in determining therapeutic strategies because the location of the tumour will affect the histological and molecular characteristics of the cancer. Phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) is a gene known to be associated with colorectal cancer location. The prevalence of PIK3CA mutations in colorectal cancer (CRC) ranges from 10-20%. Although the prevalence is small, this gene has a potential as a predictive and prognostic biomarker in the management of CRC. 80% of PIK3CA mutations occur in exon 9 (codon 542 and 545) and exon 20 (codon 1047). This study aimed to determine the prevalence of PIK3CA gene mutations based on tumour location among colorectal cancer patients in Bali, especially in Prof. dr. I G.N.G. Ngoerah Hospital, Denpasar, Bali. DNA was isolated from formalin-fixed-paraffin embedded (FFPE) blocks of colorectal cancer samples which were stored in the Department of Pathology of Prof. dr. I G.N.G. Ngoerah Hospital. Mutation was detected using polymerase chain reaction (PCR) and direct sequencing. Data on age, gender, and tumour location were recorded from patient medical records.
Our findings on 31 colorectal cancer samples showed 26 samples (96.3%) were found with heterozygous mutation in exon 9 with AC genotype, but no mutation was found on exon 20. Based on tumor location, among 26 samples with mutation, 16 samples (61.5%) were left colorectal cancer and 10 samples (38.5%) were right colorectal cancer. Further studies are needed to identify the association of this mutation with colorectal cancer location and the other clinicopathological aspects of CRC.

Published: December 2023

This article deals with the forecast of electricity production from a 50 MW photovoltaic power plant in Blitta, a town in Togo. The objective is to use meteorological variables such as instantaneous irradiation (A), wind speed (B), ambient temperature (C) and module temperature (D) to predict the active power. Multilayer Perceptron architecture, Artificial Neural Networks and multiple linear regression are explored as methods in Python. A classification of variables is presented. Certain model performance evaluation criteria made it possible to observe the results of the models. 26989 data samples are used. The results give a strong correlation between the ambient temperature of the location and the temperature of the module, i.e. 87% and 40% between the wind speed and the instantaneous irradiation. Also, as results we have: MAE = 6.017; MSE = 67.392; RMSE = 8.209; RRMSE = 15.185% and R2 = 55.321 by multilayer perceptron and 60 neurons under the hidden layer then MAE = 6.93; MSE = 77.37; RMSE = 8.80; RRMSE = 51.42%, R2 = 69.97% obtained by linear regression. This shows that there is a strong correlation between the variables used but the high values of RRMSE will drive the need to use other algorithms.

ABSTRACT

The elaboration of entrepreneurial theory into a practical realm requires serious strengthening and focus, to create people who are truly resilient in running a business. In this description, motivation and providing real examples are needed for business actors, so that they have high motivation to start and develop businesses and open jobs for the community in their environment. The main target in providing business motivation is Tea and Getuk SMEs that have potential prospects for business development, especially looking for food characteristics for Kemuning tourist destinations. This business started from trial and error without being supported by business planning, but over time it has become a promising business, evidenced by a wider market, more and more turnover and the number of employees until now reaches 15 (fifteen) people. Symptoms of significant business development from time to time recommend that business governance with all descendants of tea and getuk business activities cannot survive with the patterns that have been practiced, this is as a result of the development of problems, challenges, especially changes in consumer tastes and business competitors. It is considered necessary to adapt to the completeness of management, information technology, which is able to control the development, challenges and business problems along with the progress of the tea and getuk business. One of the main elements in controlling business development is foresight in reading business situations and problems, in anticipation of the right decisions in order to protect the onslaught of competitors and strengthen business management in the context of business progress, sustainability and sustainability.

Published: December 2023

ABSTRACT
In the field of linguistics, morphology is known which includes morphemes which are the smallest components of language, namely bound morphemes and free morphemes. In this study, bound morphemes including inflectional and derivational affixes are used. Thus, this study aimed to investigate the process of word formation and classify the types of inflectional and derivational affixes in song lyrics on Justice Justin Bieber's album. This research used descriptive qualitative. The sampling technique in this study used purposive sampling. Using the data analysis method, the researchers collected data through the Spotify application that contains inflectional and derivational affixes in each song's lyrics. The findings in this study showed that there are 88 words in the data table on song lyrics of Justin Bieber's Justice Album. Thus, the data contains 60 words in inflectional, 22 words in derivational (suffixes) and 6 words in derivational (prefixes) affixes used. Researchers can show readers, teachers and other researchers that learning a language is not enough just by listening to songs.
Introducing the Concept ‘Intra-Local Governmental Relations’ for Proper and Future Usage in Public Administration Research and Education: A Possible Case for Bathos
Authors: Shopola Arthur , Mukonza Ricky
Published: December 2023

Usage of the phrase ‘conceptual bathos’ in this paper is simply to engender curiosity of the readership but above that, it is used to caution emerging researchers [especially in the field of public administration] against overlooking or demeaning important subjects or concepts to simple or ordinary ones. Specifically, the paper refers to ‘Intra-local governmental relations’ as a concept that has suffered the same cause of negation to argue for its proper usage in future. This concept is found within the orbit of intergovernmental relations (IGR) and is a term of reference for various internal municipality relations. However, it is suspected that because of the inherent similarities and motherhood relationship between IGR and ILGR researchers have failed to draw differences thereby causing confusion. The extent of this confusion may lead to a suggestion that these concepts are inseparable and therefore can be used to explain each one’s context. The current paper characterises such acts as tangential and generalist conceptual approach which is often not aware of the important groupings (classifications) of governmental relations.  By collecting and unpacking data from the existing research outputs, books, journal articles and government publications, the current paper finally realised its objective, which was to re-introduce ILGR into the academic discourse and the anticipation is that emerging Public Administration researchers and scholars will use the concept properly and correctly.

Образцы оливкового масла (15 шт.) были получены из оливок, собранных на площадке селекционно-семеноводческого центра субтропических плодовых культур в поселке Форос (Ялта, Республика Крым) в 2022 г. Пробы масла разделяли методом жидкостной экстракции и анализировали методом газовой хроматографии на приборе Agilent Technologies модель 7820A с пламенно-ионизационным детектором на 14 жирных кислот, основные из них: пальмитиновая (С16:0), пальмитолеиновая (C16:1n9c), стеариновая (С18:0), олеиновая (C18:1n9c) и линолевая (C18:3n3). В качестве технологических параметров оливкового масла также измеряли запас масла в процентах от сырого веса ягод и среднюю массу одной ягоды. Проведенный кластерный анализ жирнокислотного состава масел позволил дифференцировать все выбранные формы оливы на три разные группы, отличающиеся между собой по морфологическим признакам (средний размер ягоды), дегустационной оценке и жирнокислотному составу масла. Форма оливы тип-1 представляла собой мелкоплодную форму (1,5±0,4 г) и обладала самым низким по значениям содержанием масла (8,5±2,4 %), дегустационным баллом (9,7±1,2) и содержанием олеиновой кислоты (62,1±0,6 %).Форма оливы тип-2 представляла собой форму со средними значениями размера ягод (2,6±0,4 г), содержанием масла (9,9±4,1 %), дегустационной оценкой масел (11,3±1,8) и содержанием олеиновой кислоты (73,6±0,7 %).Форма оливы тип-3 представляла собой крупноплодную форму, которая имела максимальные значения для средней массы ягоды (4,4±0,6 г), дегустационной оценки (11,6±1,2), содержания масла (12,3±3,4 %) и содержания олеиновой кислоты (79,7±1,2 %). Дальнейший кластерный анализ жирнокислотного состава масел выявил еще 3 группы форм, где отличия по жирнокислотному составу были минимальными. Также эти 3 формы имели мало отличий в измеренных технологических параметрах (средний размер ягоды, содержание масла и дегустационная оценка). Такое сходство могло означать то, что эти формы с большой долей вероятности являются клонами и получены с помощью вегетативного размножения. Формы с кодом 2/5, 3/4, 4/7, 5/5 имели высокое содержание и качество масла, они рекомендуются нами для внесения в реестр новых сортов оливы.

An investigation on space debris of unknown origin using proper elements and neural networks, Theory and applications of fast Lyapunov indicators to model problems of celestial mechanics

An investigation on space debris of unknown origin using proper elements and neural networks

Proper elements represent a dynamical fingerprint of an object’s inherent state and have been used by small-body taxonomists in characterizing asteroid families. Being linked to the underlying dynamical structure of orbits, Celletti, Pucacco, and Vartolomei have recently adopted these innate orbital parameters for the association of debris from breakup or collision into its parent satellite. Building from this rich astronomical heritage and recent foundations, we introduce an unsupervised learning method—density-based spatial clustering of applications with noise (DBSCAN)—to determine clusters of orbital debris in the space of proper elements. Data is taken from the space-object catalog of trackable Earth-orbiting objects in the form of two-line element sets. Proper elements for debris fragments in low-Earth orbit are computed using an ad hoc numerical scheme, akin to the state-of-the-art Fourier-series-based synthetic method for the asteroid domain. Given the heuristic nature of classical DBSCAN, we investigate the use of neural networks, trained on known families, to augment DBSCAN into a classification problem and apply it to analyst objects of unknown origin.

Theory and applications of fast Lyapunov indicators to model problems of celestial mechanics

In the last decades, we have seen a rapid increment in the use of finite-time chaos indicators in celestial mechanics. They have been used to analyze the complex dynamics of planetary systems, of minor planets and of space debris. In fact, theoretical studies on fundamental dynamical models have revealed that, computed on short time intervals, they allow to efficiently detect resonances, represent the phase portraits of complex dynamics, compute center-stable-unstable manifolds as well as Lagrangian coherent structures. In this seminar, we focus on applications of the fast Lyapunov indicator (FLI) and review through examples why its computation is particularly powerful for those systems whose solutions may have an asymptotic behavior very different from the short-term one, as it is the case of sequences of close encounters in gravitational systems and the advection of particles in aperiodic flows. The main case study which is considered is the computation of the manifold tubes and the related transit orbits in the restricted three-body problem.

Media Usage Patterns of African Higher Education Students: A Ghanaian Perspective
Authors: Senyo Loglo Frank
Published: December 2023

The study examined the media usage patterns of 598 university students in Ghana to understand their demands for digital teaching and learning, as well as their patterns of media use for learning, with the goal of informing the media selection process. Overall, the study found that the universities fell short of meeting students' expressed need for digital learning formats. The gap represents both a challenge and an opportunity for the expansion of digital teaching and learning formats in Ghanaian universities. Furthermore, the media usage patterns reveal significant leisure-seeking and recreational uses of media by students, emphasizing the pervasiveness and embeddedness of smartphones in academic contexts. The emphasis on entertainment usage and the prevalent use of media for hedonistic purposes may suggest a deficit in digital skills regarding the use of media for learning. The study found no significant differences in user profiles between traditional and non-traditional students. The implications for instructional design activities and strategies for a mobile-saturated context are discussed.

A range of business models that support or draw on open educational resources (OER) have been proposed.  This paper reviews models that have been proposed (Tlili et al., 2020; Padilla Rodriguez et al., 2018; Belleflamme & Jacqmin, 2015; Ubachs & Konings, 2016; and Farrow, 2019) and suggests a synthesis into one typology of OER business models.  The ENCORE+ OER Business Model Typology has been developed as part of a wider effort to understand and evaluate economically sustainable approaches to OER as well as to formulate OER value propositions for different stakeholders.  In related work, a range of OER innovation case studies (N=48) are being prepared for publication. These will illustrate different instances of innovation with OER and show how OER actors understand their value proposition to different audiences.

Published: December 2023

Many governments invest in digital education and deliver multi-faceted initiatives to develop the capacity of educational institutions and staff confidence in use of technology for enhanced learning and better student outcomes. However, the impact of these initiatives does not always result in improved technology-supported learning or successful digital educational products. Research shows many factors impede the achievement of such objectives. Yet, they are not well understood particularly in low-resourced educational settings. Thus, this paper as part of a larger study aimed to explore barriers to implementing TEL for higher education in low-resourced contexts and potential solutions from the perspective of educators, managers and support staff. The unique inclusion of support staff and management in this research provides a deeper understanding of current barriers to TEL, and the value of multi-stakeholder engagement to develop meaningful context-driven solutions. Using a qualitative oriented mixed-method approach underpinned by Beyond Prototypes conceptual model of TEL complex, the study found that most barriers and enablers of effective TEL implementation are related to the ecology in which it is practised, together with the influence of the salient communities. Findings also suggest that most stakeholders are aware and prioritise barriers related to their role, but have limited awareness of barriers faced by other stakeholders or how others perceived their role in supporting TEL. While the study supports findings of previous research, it adds further insight by considering the views of all implementing stakeholders and the relationships between them.
A Letter to My Former Self: The Online PhD as a Transformative Journey
Authors: Melián Efrem , Meneses Julio
Published: December 2023

Online doctoral programmes have become increasingly popular, allowing adult professionals to pursue their academic goals while carrying on with their lives. This research inquired into a seldom-explored aspect of the online PhD experience: its transformative nature. Through in-depth interviews, we investigated the impact of online doctorates on candidates’ lives and perspectives, as well as the retrospective advice they would give to their past selves at the beginning of the programme. Findings indicate that a sense of empowerment and agency is frequently rekindled in online graduate students as they rediscover their own unique voices and perspectives. The PhD also opens them up to new networks and worldviews, promoting personal and professional growth. Students’ advice emphasises the importance of having a support network to turn to in times of need, cultivating grit and time-management skills, and learning to cope with constant rejection. This paper offers insights into the lived experience of online graduate students that might interest both prospective students and programme administrators.
Future Prospects of Artificial Intelligence in Education: A Preliminary Analysis of Educator Perspectives from Focus Groups in Japan, Spain, and Germany
Authors: Bai John , Marin Victoria , Jung Insung , Zawacki-Richter Olaf
Published: December 2023

Artificial intelligence in education (AIEd) is a growing field of research that has the potential to transform learning and teaching practices. The process of developing ethical AIEd applications that are fit-for-purpose requires ongoing multi-stakeholder dialogues that include students and teachers. The present study sought to explore the perspectives of teachers in higher education on the possible futures of AIEd. Using qualitative methods, we conducted focus-group discussions in three countries (Japan, Spain, and Germany) with educators working in the social sciences. We presented participants with four scenarios that each described the implementation of a hypothetical AIEd application. A descriptive thematic analysis of the focus-group transcripts identified two key themes regarding possible future AIEd applications: 1) concerns about the validity of input variables and the accuracy of output variables, and 2) the importance of students having an active role in the integration of AI in education. These contributions highlight the importance of including teachers and students in multi-stakeholder discussions to shape the future of education.
Immersion and Implosion: Enabling Social Spaces through the Design of Interactivity at Scale
Authors: Bryant Peter
Published: December 2023

The didactic lecture is a well-established but contentious practice in higher education. It is an essentially mono-directional experience delivered in purposefully designed spaces that entrench modes of learning and expected behaviours by both staff and students. This paper will challenge the ongoing primacy of the didactic lecture in higher education and posit a dialogical alternative that supports students to interact and connect at scale through the creation of social spaces. A case study of a program at the University of Sydney Business School will interrogate the role of technology in simulating an immersive hyperreality for students in large-group teaching settings that blurs the boundaries of disciplinary knowledge and the abstractions and realties of their work, life, play and learning.
Story as Pedagogy: Leveraging Narrative Digital Learning Practices in the Instructional Design Process
Authors: Gunder Angela , Buckner Melody
Published: December 2023

This paper examines the pedagogical value of using narrative digital learning practices (NDLP) in instructional design. Through a thematic review of the literature, the authors illustrate that NDLP, which are the intentional use of storytelling techniques to inform and enhance the student experience within digital learning environments, can increase student engagement and help them meet the outcomes and goals for instruction. It discusses the different ways in which NDLP can be used to support such practices as course mapping, digital storytelling, adaptive and/or differentiated learning, scenario-based and case-based learning, gameful learning, and the application of universal design for learning principles. Additionally, the authors present backward design as a way to ensure that narrative structures used in courses are supportive of learning objectives. The future of learning is discussed, including the role of NDLP in facilitating more personalized and immersive learning experiences. The paper concludes by noting that NDLP is a valuable tool for instructional designers and educators and has the potential to transform teaching and learning through the unique affordances of narrative structure and digital tools.
Lessons from a 2-Hub Life-Science Training Course: From Heidelberg to Bangalore and Beyond

Published: December 2023

Technologies are rapidly evolving in the life sciences and other STEM areas. Advanced hands-on practical courses are key for life-science researchers to stay ahead of the game. Although the Covid-19 pandemic propelled/accelerated the transformation in remote training opportunities, it is clear that training in molecular biology methodologies requires and greatly benefits from hands-on face-to-face courses. Here we present a novel 2-hub course format, with teaching of cutting-edge technologies simultaneously in Germany (EMBL Heidelberg) and India (BLiSC in Bangalore). The format combines active-based learning on a scientific case study with collaborative exercises and networking that foster scientific exchange. We describe the digital technologies utilised in course design and delivery, and the multi-layered planning phase. Analysis of the participant and trainer feedback questionnaires demonstrates the benefits and challenges of the 2-hub format and illustrates the success of the course. The concept allows us to broaden our reach, while reducing overall CO2 emission in comparison to a 1-hub course. We show that thanks to digital tools and collaboration of dedicated organisers, we can provide conceptual design and create sophisticated active-learner training opportunities with world-wide reach.

Higher Education 4.0 (HE 4.0) is an ambitious, innovative, and collaborative project from the Atlantic Technological University (ATU), Ireland. A €12.3 million project supported by the Higher Education Authority (HEA) in Ireland under the HCI, Human Capital Initiative.  It is a vision for future agility in higher education and provides for opportunities into and through higher education.  

 

The Careers and RPL Learning Pathways platform under HE 4.0 incorporates a regional service from the ATU for the assessment of Recognised Prior Learning (RPL) and the development of personalised career and learning pathways. This new university service is delivered through an online platform at www.mycareerpath.ie and an RPL information site for the ATU at www.myexperience.ie     

  

The online MyCareerPath.ie platform involves engagement with employers and potential students to the Atlantic Technological University. The service involves advising candidates on the learning pathways available and appropriate to them, and how to achieve their career objectives or improve their employability.  

This paper will explore the ATU Career and RPL learning pathways project development journey to date and how the findings emerging from the research and evaluation activities, are informing the establishment of a regional careers and RPL service, supporting lifelong learning participation and upskilling in the workforce. In addition, the process is informing enhancements to the university’s RPL assessment process, policy development and access to higher education initiatives. To conclude, industry pilot case exemplars will be discussed and their engagement with MyCareerPath.ie assessment services, an RPL assessment portfolio and a variety of micro-courses supporting the transition to higher education.

Published: December 2023

Las crisis bancarias son un rasgo inherente del sistema financiero moderno, cuyo impacto y probabilidad pueden reducirse mediante la generación de confianza. Quienes pueden generar
esta confianza en el sector bancario son principalmente las propias entidades, si bien con una estrecha vigilancia ex-ante y actuaciones rápidas y decididas cuando surge una crisis bancaria,
las autoridades pueden contribuir a reforzarla. La Junta Única de Resolución, como autoridad de resolución central de la unión bancaria, se ha constituido como un elemento fundamental
del marco regulatorio tras la crisis financiera global y que ha fomentado la confianza en el sector bancario al aumentar la resolubilidad de las entidades.
