Staff Development for networked learning
Authors: Weedon Elisabeth , Broumley Liz , MacLean Colleen
Published: December 2024

This study explores, through a case study the impact of both formal and informal staff development. It is suggested that the Kolb cycle and socials constructivist theory provides a useful starting point for exploring development drawing on data gathered in interviews, a focus group session which can then triangulated with data from other sources. However, it is also recognised the there may be a need for developing the Kolb cycle into a helix to account for reflection on experience which subsequently guides future action. Different types of staff development are then considered, distinguishing between formal and informal staff development. Finally issues arising out of these studies are identified and future areas for research suggested.
Can Web-Based Environments Talk the Talk?
Authors: Wheeler Matthew
Published: December 2024

This paper aims to discover what current student democracy / advocacy systems are prevalent within higher education institutions; focusing upon the communication between learners and their educators. The paper raises two questions; do the current democracy systems work (the learners perceptions)? And could a web-based environment assist the learners and educators to communicate in a more effective way? A case study of the operations within a new web-based environment (V-Rep) will be included as a comparison to the current systems. The study finds that web-based environments would be a useful addition to the current systems available within higher education institutions. The implications for the current systems are not great, as the web-based environment is aimed at enhancing communication between the learners and their educators, not to replace them.
Working across Professional Boundaries
Authors: Atkinson Adele , Start Kath
Published: December 2024

As an individual matures, their self-concept matures from dependence to self-direction (Knowles, 1990). Strategies to foster self-directedness should aim to progressively decrease dependence on the educator, foster decision making and facilitate the application of theory to practice (Mezirow, 1981;Knowles, 1990). Problem based learning is one such strategy. It is student-centred and attempts to replicate issues that students see in practice (Amos and White, 1998).

How was it for you? Student and staff experiences of e-learning
Authors: McDowell Liz , Gannon-Leary Pat
Published: December 2024

The poster will illustrate work in progress on a set of case studies designed to illuminate staff and student experiences of learning, teaching and assessment using a virtual learning environment (VLE). The University of Northumbria began to implement the Blackboard VLE (http://www.blackboard.com) during the 2000/2001 academic year. Blackboard is now being used across a range of courses in all Faculties. The type of use varies, including the provision of electronic access to learning resources to assist on campus learners; the use of communication facilities to enhance flexible learning; and the use of a wide range of VLE facilities for distance learning courses. Use and impacts are being monitored and evaluated in a range of ways but here we report on a qualitative element of the evaluation.

Authors: Whitehouse C. M. , Durbin C. S. , Shah H. U.
Published: December 2024

The New Opportunities Fund ‘ICT for Teachers’ initiative, aimed to deliver professional development training for all ‘serving’ teachers in the UK . The scale of the task, suggested that an alternative delivery format to traditional face-to-face training should be trialled. SIfT, as an approved training provider to the Government scheme, has created a highly structured model for designing and delivering course materials to remote learners, via a Virtual Learning Environment. The poster session includes a demonstration of SIfT content and illustrates the SIfT model, consisting of the ‘12 Unit grid’, ‘Coursework framework’, ‘virtual tutor’ and ‘navigational features’, developed within the virtual space.
Symposium 2: Change for networked learning
Authors: Beaty Liz , Cousin Glynis , Deepwell Frances , Banks Sheena , Powell Adrian
Published: December 2024

This symposium aims to bring together research on the management of change issues in the introduction of elearning in higher education.. Networked learning has thrown many challenges to the current structure and organisation of higher education. Universities have been variously attempting to make use of opportunities of the new technology and at the same time to respond to the inevitable consequence of rapid system changes. The volatile nature of change in higher education has prompted many experiments and the papers in the symposium will report on research from major change initiatives within institutions and across institutions.
The research papers report on the effects of strategic management and policy direction. The research has mainly been conducted as action research and case study research. The findings are based on longitudinal analyses of implementation of strategies over a period of three to four years. Two of the three papers (Coventry University and University of Sheffield) are based on individual institutions in England where different approaches have been taken to the introduction of elearning and the third is based on an analysis of trans-institutional change fostered in Scotland through the Virtual Learning Space (VLS) initiative.
The Symposium will contribute to the conference themes of elearning, and the e-University, and to methodologies for researching networked learning. In relation to the first theme this symposium will focus on institutional level issues of management and policy and consider the aims and appropriate structure for universities in a networked world. The research reported will also offer a contribution to issues of researching the management of change in networked learning. The case studies reported are of a wider scope than many existing case studies and have data related to an era of unprecedented change which may in time be viewed as transformational.

Published: December 2024

This paper will describe the TILE MLE, which comprises a learning content management system and an educational delivery system; it will focus on the former as the delivery framework has been described elsewhere. From a pedagogical point of view, content creation and delivery are the two key factors in web-based learning systems. When supported by the Internet, content delivery are relatively cheap. But creating high quality online learning content is very expensive. Currently different organizations are creating similar content for their own need, with little reuse of content. This is a waste of valuable resources and is the reason why there is an imperative need for standards-compliant content management systems to facilitate content development and deployment. E-learning content management systems face the challenge of collecting, organizing, managing, maintaining, re-using, delivering and targeting the content. We must differentiate between a content-management system and authoring tools for content creation. The latter are used to create content that is organised into a course. This may be animations, graphics, text, audio, video or other multimedia segments. These learning objects are organised and catalogued by the learning content management system and this creates units of study or on-line courses that can be navigated and perhaps monitored. That unit of study usually has structure, which may include hierarchy and precedence. An LCMS should support the management of any content level, which includes multimedia segments, learning objects or units of study. The design of such a system is described her, together with an analysis of the issues considered.

Correcting Severe Relapsed Hallux Varus Using Hexapod Circular External Fixator
Authors: Galal Sherif
Published: December 2024

Congenital hallux varus is an unusual condition in which the big toe is medially angulated at the metatarsophalangeal joint. Different surgical methods have been described to correct it; however, there is always a risk of recurrence. The multiplanar nature of the deformity and the disrupted anatomy from a previous surgery make recurrent cases difficult to treat. A 16-year-old adolescent boy presented with a recurrent hallux varus deformity after a previous surgical correction. This case report describes its successful treatment using a hexapod circular external fixator as a salvage procedure.
The clipped language revolution: Exploring clipping in contemporary Social media English
Authors: Dragusin Elena Denisa
Published: December 2024

The proliferation of social media platforms has catalysed a linguistic revolution, characterized by the widespread adoption of clipped language forms. This article investigates the phenomenon of clipping in contemporary social media English, shedding light on its linguistic features, functions, and socio-cultural implications. Through an interdisciplinary approach drawing on linguistics, sociolinguistics, and digital communication studies, this research delves into the mechanisms and motivations driving the prevalence of clipping in online discourse. Clipping refers to the process of shortening words or phrases, often resulting in informal and condensed linguistic expressions. This study examines various types of clipping observed across different social media platforms. It investigates how these clipped forms serve communicative functions such as facilitating rapid interaction, expressing solidarity within online communities, and constructing digital identities. Furthermore, the article explores the role of clipping in the evolution of language norms and the negotiation of linguistic authenticity in digital spaces. Through a combination of qualitative analysis and quantitative data collection, this research offers insights into the linguistic creativity and innovation inherent in clipped language usage on social media. By examining real-world examples and user practices in the current digital age, it provides a comprehensive understanding of the multifaceted nature of clipping in contemporary online communication which is to be found at the intersection of language change with technology and sociocultural dynamics.
The Dialogue in the Pragmatic Construction of the Discourse
Authors: Sterian Dan
Published: December 2024

In a fiction or non-fiction text, the dialogue and the dialogues also trigger a whole series of phenomena, as they are always supposed to bring about a certain progress at the discursive level, at the thought level or at the level of the interlocutors’ logos. Consequently, they are liable to ensure the passage from a conscience that is sometimes subject to contingencies to a more enlightened, if not emancipated conscience. Any dialogue presupposes a logical sequence of lines, and the transition from one line to another can be made in different ways: when one participant cuts another off, this phenomenon is called an interruption and is graphically translated by three dots (...); when the interlocutor changes the subject, there is a refusal to reply. Word sequencing involves the repetition of the words and expressions used by one character/speaker by a second character/speaker. Finally, idea sequencing is done by picking up on a theme initiated by one character and developed by another. Dialogue as a representation takes different forms depending on the type of text in which it appears.
Richard the IIIrd and Macbeth: The Image of the Tyrant in the Work of William Shakespeare
Authors: Taragan Elena
Published: December 2024

This article discusses a number of defining traits of the tyrannical personality, as described by William Shakespeare through the outlining of the characters Richard III and Macbeth. The factors that determine the propensity towards tyranny and the context in which the rise towards tyranny occurs are listed. Richard III and Macbeth remain in the history of universal literature as characters who stepped on the path of inhuman deeds, for different reasons, but whose paths are similar in that, once they become tyrants, the crimes committed generate other crimes, the evil amplifying- and distancing the protagonists from any possible source of light. The nuanced differences between the temperaments of these two characters are punctuated, both mirroring the tyrannical personality, but presenting particular ways of relating to the world. Both undertake reprehensible actions, the destruction and evil take on ever-increasing proportions, but it is noticeable that there are differences in the degree of morality that each of these two characters embody. Carrying out this study, we observe the finesse of Shakespeare's psychological analysis in rendering the evolution and development of human character in certain contexts that favor the pact with lawlessness.
Traduction en roumain des néologismes stylistiques et des occasionnalismes de l’oeuvre d’Eugène Ionesco
Authors: Graur Elena
Published: December 2024

By his bilingualism, belonging and contradiction to two identity spaces, Ionesco gave birth to individual creations, composing a spectral kaleidoscope of plurinomy and revealing the largely incongruous artistic personality. Far from being chaotic, the Ionescian authorial strategy imposes its coherence and its significant potential for success by intelligently surviving models and the passage of time. As an expression, pragmatically denying not only the established models, but even their essential order, the Ionesian dramaturgy initially proposes an anti-theatricality which seems/claims itself, in fact, fixed in the horizon of the non-theatricality. Eugène Ionesco’s work illustrates a poetics of the fragmentary and intermittency as a system, culminating in an aesthetic of precariousness (and semantics) pursued as it becomes converted into a single form of life. apparently paradoxical: syncopated persistence, continuous return, revalorization, resemantization, recuperation. It includes everything: homoioteleuts, counterpètries, approximate homonymy. Writing like Ionesco means playing, inventing, creating, making full use of the freedom that confers the imagination, the literary image. He loves words and he baptizes them.
The experimental approach of anxiety in early school age students
Authors: Calancea Angela
Published: December 2024

The article includes the results of an experimental study of anxiety in young school-age students. To uncover the levels of manifestation and the specifics of anxiety in school-age students, we applied the following tests and scales: the projective test "CCO", the self-esteem assessment test "Scărița", and the anxiety test by R. Temml, M. Dorc, and V. Amen. As a result, we found that many students register moderate to high levels of anxiety. The issue of anxiety in contemporary psychology requires a multidisciplinary and holistic approach, and efforts to reduce stigmatization are crucial for promoting a more comprehensive understanding of anxiety and improving mental health outcomes. Common features of anxious experiences in young school-age students include separation anxiety, social anxiety, academic performance anxiety, perfectionism, fear of teachers or authority figures, physical symptoms, avoidance behaviors, test and performance anxiety, safety concerns, difficulty concentrating, behavioral changes, and a need for reassurance. Understanding these characteristics can help educators, parents, and mental health professionals identify and support young school-age children experiencing anxiety. Early intervention and a supportive environment can play a crucial role in helping these students develop healthy coping mechanisms and resilience.
Contemporary problems of education: the school and the family
Authors: Cumpanasoiu Teodor Sorin
Published: December 2024

Freire (1999) states that: "Education alone does not make society, without it society does not change either. If the option is progressive, if you are in favor of life and not death, fairness and injustice, not right and not arbitrariness, different coexistence and not your denial, not if there is another way if not to live the option you choose. Embody it, reducing the distance between what you say and what you do”. The Romanian education system has experienced major changes in recent years, advancing in some aspects but also creating leverage for contemporary education. A very challenging issue is the involvement of the family in school, as the convivial alienation of the family becomes more evident every day. It is observed that the performance of students whose parents accompany their school development is positively differentiated from students who do not receive such follow-up. The decrease in family participation in the student's school life generates, in most cases, a learning deficit and, therefore, school failure. It is certain that both the school and the family need each other because this interaction must take place to ensure success and good performance. Kant (1993) says that man must be educated and that such education includes two planes: one from outside to inside and from inside to outside. It can be said that the student needs to get involved in the environment that will have the opportunity to transform it, to modify it, so that through this external influence he can internalize this modification and at the same time act constructively on the school environment. The school actually needs to inform, involve, and get closer to the family, and the family needs to do the same to ensure this success.
Stigmatization in the social context: an analytical investigation of negative labeling and its implications on relationships and social integration
Authors: Balan Ecaterina
Published: December 2024

The article explores the concept of stigmatization, tracing its historical origins and evolving into contemporary scientific aspects. It discusses the branding of Greek slaves and the stigmata associated with Christian saints, highlighting the term's evolution in a social context. Authors, including Erving Goffman [4], are acknowledged for their contributions to understanding stigma in sociology. The article emphasizes the importance of a clear definition of stigma, distinguishing between felt (internal) and adopted (external) stigma. It explores the dimensions and consequences of stigma in various social and psychological contexts, as well as the influence of dominant groups in setting stigmatization criteria. Aesthetics and the impact of aesthetic qualities on social perception are discussed, underscoring how aesthetic stereotypes can contribute to stigmatization. Controllability of stigma, cultural beliefs, and the concept of "stigma by association" are also addressed in the context of stigmatization. The article highlights the complexity of stigma and the need to address this issue in diverse contexts. It concludes by emphasizing that stigmatization is not merely a simple label but a complex, interconnected social construction affecting individuals in multiple ways.

Nostalgia is a frequently addressed concept in interdisciplinary studies and research aimed at identifying its psychological correlates and the impact of this phenomenon on emotional states and individual adaptability, particularly in the context of crises and social changes. Nostalgia for the past is a strong emotional experience that reflects the desire to relive the positive aspects of previous experiences, related to various significant moments in a person's life, perceived as better or happier than current circumstances.
Social intervention paradigms in the context of new social realities
Authors: Haraz Svetlana , Dontu Mihaela , Druta Alina
Published: December 2024

In the last 20 years, increased attention has been paid to child mental abuse, but despite all this, the problem still requires the input of mental health professionals from all over the world. We analyzed articles and international guidelines related to the management of psychological trauma among children and young people in order to identify the practices with the most promising clinical results. We have observed that exposure to a traumatic event will generally cause short-term emotional distress followed by possible long-term psychological damage and that due to the diverse cultural environment and individual perception of the event, cognitive-behavioral therapies should be the first line of treatment with folding on the cultural structure of the patient. Therapies such as desensitization and reprocessing of the traumatic event are offered to the patient in individual therapy sessions, and the quality of the psychotherapeutic act depends on the relationship between the therapist, the patient, and the family, which are the starting points for a successful recovery. To help the child process the traumatic event and return to previous functionality, numerous sets of best practices are developed worldwide, endorsed by world and national psychiatric associations, but an evaluation of current policies and procedures is needed to identify gaps and implement stricter and clearer measures. The results of these measures would help create a safer and more supportive environment for children, ensuring that the adults around them are well-trained to recognize and intervene in the event of emotional and psychological trauma. Families of traumatized children also need support. Services that provide family counseling and training can help parents better understand and manage their children's needs. Also, involving the community in providing support can create a safer and more supportive environment for all its members.
The role of the social assistant in grieving management
Authors: Danut Simion
Published: December 2024

The social worker plays an essential role in dealing with and managing bereavement, although this contribution is not always considered to be necessary. According to his responsibilities, he is involved in the prevention of potential individual or collective problems that can lead to the experience of pain by identifying both the intervention to the possible causes of pain and loss and offering direct support and emotional care to those going through the mourning process. During this difficult time, the social worker supports those affected to navigate and cope with these emotions and challenges. Another crucial aspect of the social worker is the development of personalized action plans and assessment of individual or group needs; through this approach to pain management, an attempt is also made to identify the essential support resources to overcome this period. In this article, we want to understand the role of the social worker in grief management by providing emotional support, education, and guidance to identify and mobilize the necessary resources to overcome this difficult period.

Benefits of logic model for program evaluation planning
Authors: Bulat Violeta
Published: December 2024

The cornerstone of an effective evaluation is an intimate understanding of the program under consideration. Hence, logic models can be very useful in evaluation planning since they provide the evaluator with a visual depiction of how the program is supposed to work. Logic models can help evaluators better match the evaluation to the program by helping them focus on critical components of the program. As an advance organizer, the logic model aids the evaluator to focus on the important elements of the program and to identify what evaluation questions should be asked and why, as well as what measures of performance are key. If a particular result is included in the logic model, then it generally should be included in the evaluation as a factor to track and measure. The logic model can help the evaluator prioritize where to spend the limited resources allocated to the evaluation. It helps the evaluator focus more specifically on what information stakeholders really need to know about the program. If a logic model does not exist when the evaluator is hired, it will be extremely useful if the evaluator, in collaboration with various stakeholders, works to create one.
The relationship between emotional intelligence and academic performance of young school-aged pupils
Authors: Iurchevici Iulia
Published: December 2024

This article aims to reveal the role of emotional intelligence in achieving academic success. Although much research has explored the relationship between these two variables, few studies have focused on early school age. Through the empirical study presented in this article, we sought to answer the question: Does emotional intelligence influence the academic performance of primary school students? The analysis of the obtained results allowed us to answer this question affirmatively, as we found a direct proportional relationship between emotional intelligence and the academic performance of primary school students. Subjects who had a low level of expressing and appreciating their own and others' emotions also showed a low level of using emotions in solving school problems. The academic performance of students increased following a psychological intervention program aimed at developing and capitalizing on their emotional intelligence.

Published: December 2024

Over time, the large size of some tumors has been described with fascination. The term “giant” is frequently used to refer to these large gynecologic tumors. Also, to call them “giants”, their measurements >10 cm, >15 cm, >20 cm are usually used, and sometimes the limits for their defini-tion are not mentioned. Others define “large” as those >5 cm, those measur-ing 10-20 cm or those reaching above the umbilicus. In the English-speaking literature, there has been an agreement for more than 53 years on defining uterine or ovarian tumors weighing more than 25 lb as “giants”, because, in 1971, Beacham et al, reviewed the uterine or ovarian tumors reported between 1946-1970, weighing 25 lb. or more. The present study aimed to report the clinical characteristics and management of four uncommon cases of giant tu-mors, with good surgical management, that evolved successfully and without complications. We defined as “giants”, gynecologic tumors weighing 25 lb or more and the used parameter was weight, not measurements. Four tumors were benign, cystadenoma-type, and three serous. Two patients were nulliparous, and two were of indigenous race. All four patients were of extreme ages. The tumors weighed 46.738, 65.256, 26.675 and 27.116 lb (21.200, 29.600, 12.100 and 12.300 kg).

Effectiveness of Corporate Tax Incentives in Attracting Investments
Authors: M Dr. Kiran Kumar , Pawar Vishal M , Antony Sukeerth , Sarkar Bikramaditya
Published: December 2024

Corporate tax incentives are widely used by developing nations to attract investments, stimulate economic activity,
and drive industrial growth. This study investigates the effectiveness of these incentives in achieving their intended
goals by analysing macroeconomic data from a diverse sample of developing economies over the past two decades.
The research focuses on the relationship between tax policies and key investment indicators such as foreign direct
investment (FDI), domestic capital formation, and economic growth metrics like GDP, employment, and productivity.
Using a combination of panel data regression and time-series econometric techniques, the study identifies critical
factors that mediate the success of tax incentives, including the quality of governance, infrastructure development,
and ease of doing business. Preliminary findings suggest that while corporate tax incentives are effective in attracting
short-term investments, their long-term impact on economic growth is contingent on broader economic and
institutional frameworks. The analysis also highlights potential trade-offs, such as revenue loss and inequality,
stemming from poorly designed tax policies.
This paper contributes to the literature by providing empirical evidence on the conditional effectiveness of tax
incentives and offering actionable policy recommendations. The findings aim to assist policymakers in designing
balanced tax regimes that promote sustainable economic growth without undermining fiscal stability.
Smart Healthcare Prediction Using Machine Learning

Published: December 2024

In this paper, the utilization of machine learning
techniques in the healthcare system is introduced. As the
healthcare industry generates increasingly vast amounts of data
daily, manual processing by humans becomes impractical for
prompt disease diagnosis and treatment decisions. To address
this challenge, data management techniques and machine
learning algorithms are explored in healthcare applications to
facilitate more accurate decision-making processes. Detailed
descriptions of medical data are provided, enhancing various
facets of healthcare applications through the adoption of this
cutting-edge technology. Naïve Bayes machine learning
algorithm is employed to train the machine for predicting
various diseases, extracting new patterns from extensive
datasets to enable predictive analysis and derive knowledge
linked to these patterns. A key focus lies in acquiring data
automatically or semi-automatically, highlighting the
significance of this process.

A novel framework for electrocardiogram beats recognition based on Hjorth parameters and inferential statistics
Authors: Purboyo Tito Waluyo , Naufal Dziban , Putra M. Darfyma , Kurniawan Ekki
Published: December 2024

This paper presents a novel statistical framework for detecting abnormalities in cardiac beats using Hjorth parameters—Activity, Mobility, and Complexity—derived from ECG signals. The proposed approach leverages the Kolmogorov-Smirnov (KS) 2-Sample Test to quantify the differences between normal and abnormal heartbeats across multiple ECG leads. Unlike traditional methods, our framework focuses on the statistical properties of Hjorth parameters to enhance the accuracy of arrhythmia detection. The framework utilises a multi-lead analysis to accurately differentiate among various beat types, such as regular, APB, PVC, and timed beats, demonstrating a high level of sensitivity. The results demonstrate that specific Hjorth parameters, particularly Activity in Lead II, are highly effective in differentiating between normal and abnormal beats, achieving KS scores as high as 0.99. Additionally, the framework reveals the importance of multi-lead ECG analysis in improving the reliability of beat classification. This study not only introduces a cost-effective and robust method for arrhythmia detection but also lays the groundwork for future research aimed at developing more accurate diagnostic tools based on the statistical analysis of ECG signals.
Perceived solutions to curtail the surge in crimes at petrol stations in South Africa
Authors: Nyahunda Louis , Rakubu Kholofelo Anna
Published: December 2024

The surge in crimes at petrol stations in South Africa is a fundamental concern for business owners, policymakers, researchers, and the public. If the challenge remains unaddressed, it poses serious drawbacks towards the realisation of sustainable development and community safety aspirations. The surge in crimes at petrol stations bears significant societal and economic impacts. This article explores perceived solutions to address this conundrum drawing from the views of petrol station owners, community members and fuel attendants. A qualitative research approach was adopted within the exploratory research design. A purposive sampling technique was adopted and a total of 25 respondents participated in the study. Semi-structured interviews were used as data acquisition methods. The findings revealed that to curb crime at petrol stations, there is an urgent need to enhance security and policy visibility. The findings further revealed that a multifaceted approach is required which involves stakeholder collaboration, practical implementation of Crime Prevention Through Environmental Design, embracing technology and training of fuel attendants. This article submits that addressing the underlying socioeconomic factors that contribute to the rise in criminal activities, such as poverty, unemployment, and lack of educational opportunities, may help mitigate the long-term drivers of these issues. Also, awareness raising and community engagement can stimulate crime prevention efforts and may yield positive results in curtailing the surge in crimes at petrol stations.
