Towards the acceptance of RSS to support learning: An empirical study to validate the technology acceptance model in Lebanon

Simpler is better. There are a lot of "needs" in e-Learning, and there's often a limit to the time, talent, and money that can be thrown at them individually. Contemporary pedagogy in technology and engineering disciplines, within the higher education context, champion instructional designs that emphasize peer instruction and rich formative feedback. However, it can be challenging to maintain student engagement outside the traditional classroom environment and ensure that students receive feedback in time to help them with ongoing assignments. The use of virtual learning platforms, such as Blackboard Learn, and web feed syndication, using technology such as Rich Site Summaries (RSS), can help overcome such challenges. However, during an initial pilot at an institution in Lebanon, only 21% of students reported making use of both these facilities. In this study, the Technology Acceptance Model (TAM) was used to guide the development of a scale to be used to investigate antecedents to the use of web feeds. The proposed scale was reviewed by 4 experts and piloted with 235 students. The collected data were analysed using structural equation modeling (SEM) technique based on AMOS methods. The results revealed adequate face, content, and construct validity. However, perceived ease of use was not a significant predictor of attitude towards use. Overall, the proposed model achieves acceptable fit and explains for 38% of its variance of which is lower than that of the original TAM. This suggests that aspects of the model may lack criterion validity in the Lebanese context. Consequently, it may be necessary to extend the scale by capturing additional moderators and predictors, such as cultural values and subjective norms. We concluded that the existence of RSS feeds in education improves significantly the content presented by the instructors to the e-learning user decreasing at the same time the size and access cost

Appreciate we are individual humans with previous experience : An exploration of sessional marker experiences

Continuous increase of global reliance on sessional staff in higher education has not been accompanied by the development of strategies to enhance quality learning and teaching or understanding the experiences of these staff. This has resulted in a general discontent among this category of academics. The growing importance of building respectful working environments that integrate inclusive care and performance quality leads to the emergence of standards frameworks. Explorations of sessional staff lived experiences are vital to inform policy and practice. This study examined sessional staff predominantly in a marking role in a local context of an Aotearoa/New Zealand University. We explored our markers’ agreement with selected principles of an Australian national framework. Based on an anonymous Qualtrics survey, the quantitative data showed our markers agreed with most of the selected Australian framework principles at the individual and department levels. An appreciative inquiry of the qualitative data identified markers’ desires for increased professional development, infrastructure and resources, and personal motivation. Considering our markers’ experiences, we propose several actions in a workshop format to provide insights for developing better structures and policies for retaining, training, and engaging with sessional staff

A Wolf in Sheep’s Clothing? Critical Discourse Analysis of Five Online Automated Paraphrasing Sites

Research on academic integrity used to focus more on student character and behaviour. Now this research includes wider viewing of this issue as a current teaching and learning challenge which requires pedagogical intervention. It is now the responsibility of staff and institutions to treat the creation of a learning environment supporting academic integrity as a teaching and learning priority. Plagiarism by simply copying other people’s work is a well-known misconduct which undermines academic integrity; moreover, technological developments have evolved plagiarism to include the generation and copying of computer-generated text. Automated paraphrasing tool (APT) websites have become increasingly common, offering students machine-generated rephrased text that students input from their own or others’ writing. These developments present a creeping erosion of academic integrity under the guise of legitimate academic assistance. This also has implications for arrival of large language model (LLM) generative AI tools. In accessing these sites, students must discern what is a legitimate use of the tool and what may constitute breaching academic integrity. This study critically analysed the text from five online paraphrasing websites to examine the discourses used to legitimise and encourage APT use in both appropriate and inappropriate ways. We conceptualised these competing discourses using Sheep and Wolf metaphors. In addition, we offer a metaphor of the Educator as a Shepherd to become aware of APT website claims and assist students to develop critical language awareness when exposed to these sites. Educators can assist students with this through knowledge of how these sites use language to entice users to circumvent learning

Stromal Stem Cells: Nature, Biology and Potential Therapeutic Applications

Stromal cells are connective tissue cells of any organ. Mesenchymal stromal cells (MSCs), are multipotent progenitors, which were first described by Caplan and colleagues in 1991. MSCs hold great potential for regenerative medicine because of their ability for self-renewal and differentiation into tissue-specific cells such as osteoblasts, chondrocytes, and adipocytes. Recent studies indicate that MSCs resemble pericytes and emerge from the peripheral stromal region surrounding blood vessels, thus clarifying their broad regenerative potential in adult tissues. The development of uniform protocols for both preparation and characterization of MSCs, including standardized functional assays for evaluation of their biological potential, are critical factors contributing to their clinical utility. Nowadays, due to the capacity of modulating immunological responses, supporting hematopoiesis and repairing tissues, MSCs have been widely used to treat immune-based disorders, such as Crohn’s disease, rheumatoid arthritis, diabetes, and multiple sclerosis. Based on animal experiments and clinical studies, the most successful clinical application of MSCs is in the field of hematological disease

Pelvic Electrical Neuromodulation for the Treatment of Overactive Bladder Symptoms

Overactive bladder syndrome negatively affects the daily life of many people. First-line conservative treatments, such as antimuscarinics, do not always lead to sufficient improvement of the complaints and/or are often associated with disabling adverse effects leading to treatment failure. Electrical stimulation of the sacral nerves has emerged as an alternative and attractive treatment for refractory cases of bladder overactivity. Few theories attempted to explain its mechanism of action which remains elusive. It involves percutaneous posterior tibial nerve stimulation and more commonly sacral neuromodulation. For the latter, temporary sacral nerve stimulation is the first step. If the test stimulation is successful, a permanent device is implanted. The procedure is safe and reversible. It carries a durable success rate. The technique should be combined with careful followup and attentive adjustments of the stimulation parameters in order to optimize the clinical outcomes. This paper provides a review on the indications, possible mechanisms of action, surgical aspects and possible complications, and safety issues of this technique. The efficacy of the technique is also addressed

Rectus Fascia Sling for the Treatment of Total Urethral Incontinence in Males

Objectives: Urinary incontinence in patients with neurological disease is a major health problem. A modified rectus fascial sling has been assessed in incontinent male patients.Patients and Methods: Fourteen adult male patients with total incontinence due to neurogenic or post-traumatic and etiology were included in this study. A rectangular rectus sheath flap was harvested and defatted.The flap was placed around the bulbar urethra and sutures were passed both in front of and behindthe pubic bone. Both sutures on each sidewere tied to each other over the pubic bone.Results: Of the 14 patients, 9 (64.3%) were completely dry, 3 (21.4%) reported improved continence, while 2 (14.3 %) were a failure. In total, 71.4% of the patients showed significant improvement using the Incontinence Quality of Life (IQoL) questionnaire. A significantdecrease in the number of pads used per day of 61.3 % (

Rolled vaginal wall flap for the treatment of stress urinary incontinence

Objectives: Anterior vaginal wall slings (AVWS) have been used for decades in the treatment of female stress urinary incontinence (SUI). The main drawback of using the vaginal wall as a sling is its tendency to weaken and stretch over the course of years. The use of synthetic tapes for the treatment of SUI is effective but costly. For patients who cannot afford synthetic tapes, we describe the preliminary results of a modified AVWS technique for the treatment of SUI types II and III.Patients and Methods: In this series, a modification of the AVWS was applied in 35 female patients with SUI. A fortified and rolled flap is used to provide compression and support of the urethra. The vaginal mucosal surface of the flap is cauterized and two diagonal sutures are placedacross it. The flap is then rolled on itself with a running 2/0 vicryl suture. Two sutures attached to both ends are passed retropubically to the anterior abdominal wall and tied over the rectus sheath.Results: All 35 female patients had type II/III SUI. After a median follow up of 43 months, 91% of the patients were dry or used 0-1 pad per day. Only one patient suffered from transient retention for one week post-operatively.Conclusion: This is a simple method to reinforce vaginal wall flaps. It could offer a durable and effective option for the treatment of SUI in patients who can not afford synthetic tapes. Long-term follow up is required to evaluate the durability of the procedur

Estabilización de aceite de oliva virgen extra ecológico con antioxidantes naturales de hojas de Artemisia absinthium obtenidos por maceración y extracción asistida por ultrasonido

Olive oil is the most popular product derived from Olea europaea L. due to its organoleptic characteristics and its beneficial effects on human health. Nowadays, there is a growing interest in olive oil enrichment with medicinal plants. In this regard, Artemisia absinthium L. is an edible source of antioxidants. The aim of the present study was to improve the oxidative stability and the nutritional value of Organic Tunisian Chetoui Olive oil by its enrichment with the phenolic compounds in Artemisia absinthium. The enrichment carried out by maceration and ultrasound-assisted extraction did not affect the organic criteria of olive oil. The comparative study, performed during one year of storage, showed that ultrasound-assisted extraction led to the lowest final peroxide and extinction coefficient values. At the end of storage, this method increased oleic acid content and biophenol contents. Furthermore, the anti-radical activities of enriched samples were higher than the control.El aceite de oliva es el producto derivado de Olea europaea L. muy popular debido a sus características organolépticas y sus efectos beneficiosos para la salud humana.

Perception of contracing parties on construction safety in the Gaza Strip, Palestine

The construction industry is one of the most hazardous industries in developing countries. Understanding the safety climate or culture of a workplace, the perceptions and attitudes of the workforce are important factors in assessing safety needs. The construction industry in Palestine, by its inherent nature, is susceptible to potentially dangerous conditions that affect the safety of all personnel working in construction projects. This paper reports, based on a questionnaire survey, the perception of owners, consultants, and contractors towards safety in constructions in the Gaza Strip. The results showed that, most of the participants in the survey had accidents in their construction projects. The findings indicated that, the main causes of fatalities and injuries are falling from heights, dropped objects and materials, and being caught under excavations. Carelessness of workers, lack of safety knowledge, and lack of safety training are the main three reasons that contributed to the increase rate of accidents among construction workers in the Gaza Strip. Therefore, contractors should prepare safety training programs which help personnel to carry out various accidents accidents preventive activities effectively. Training material should discuss the costs of accidents, the influence of good safety performance, and should stress the safety objectives of the company, the relevant laws and legislation, and contractual relationships with clients regarding safety matters
