Large Language Models as Planning Domain Generators (Student Abstract)

The creation of planning models, and in particular domain models, is among the last bastions of tasks that require exten- sive manual labor in AI planning; it is desirable to simplify this process for the sake of making planning more accessi- ble. To this end, we investigate whether large language mod- els (LLMs) can be used to generate planning domain models from textual descriptions. We propose a novel task for this as well as a means of automated evaluation for generated do- mains by comparing the sets of plans for domain instances. Finally, we perform an empirical analysis of 7 large language models, including coding and chat models across 9 different planning domains. Our results show that LLMs, particularly larger ones, exhibit some level of proficiency in generating correct planning domains from natural language descriptions

Investigating Students’ Behavioral Intentions towards a Smart Learning Platform Based on Machine Learning: A User Acceptance and Experience Perspective

This study investigated students’ behavioral intentions toward a smart learning platform. In order to evaluate and implement the adoption model within the context of Thai education, an empirical study was conducted. On a sample of 1,250 pupils from throughout Thailand, an analysis technique known as structural equation modeling was used to evaluate the proposed research model. Results from the study showed that the adoption of smart learning platforms by students was most significantly impacted by attitudes towards using them. This was followed by internal variables, namely the Perceived Ease of Use (PEU) and Perceived Usefulness (PU) of the platforms. In addition, Accessibility (AC), Personalization (PL), and Perceived System Quality (PSQ) are peripheral factors that increase understanding of smart learning platform adoption. The findings of this study align with other research, with the exception that only AC had a detrimental impact on PEU. Therefore, this study will provide valuable insights for scholars and researchers by filling a knowledge gap in the existing literature and demonstrating the concrete use of a proficient smart learning platform in the realm of academic success.

From Crisis to Continuity: Exploring Students’ Perspectives on the Future of Online Learning Beyond COVID-19

As we live in the post-COVID-19 era, much research should be devoted to guiding educators and policymakers on what to retain, revise, or even eliminate from the online learning experience. This study aimed to provide a deeper understanding of the students’ behavioural intention to continue using technology in the post-COVID-19 era. The study was grounded in a well-known theoretical model for assessing technology adoption, the Technology Acceptance Model (TAM), expanded by adding the following external variables: accessibility (ACC), anxiety (ANX), feedback (FB), computer playfulness (CP) and perceived enjoyment (PNJ). A total of 134 undergraduate students from both public and private universities and colleges in Oman were included in the study. Data was collected through the administration of a Likert-scale questionnaire and analysed using descriptive tests and the Smart-PLS technique. The study’s main findings revealed that ACC, ANX, CP, and PNJ had a significant impact on Perceived Ease of Use (PEOU), while no such effect was observed on Perceived Usefulness (PU). Notably, the study concludes that students exhibit a high intention to continue using technology. The study underscores the increasing familiarity of interactive technology tools among teachers and students, a trend accelerated during the pandemic. However, a recommendation is made for the development of a comprehensive framework by educational stakeholders, including policy professionals and teachers, to specify the strategic use of technology and its intended purpose.

Vascular access in cardiac implantable electronic devices: a systematic review and network meta-analysis

Abstract Background Despite the increasing number of cardiac implantable electronic devices (CIED) implantations worldwide, gaps in the evidence base on the optimal venous access to perform the procedure still exist and direct comparisons of different techniques are lacking. Purpose The aim of this study was to compare the acute and long-term safety and efficacy of the three main vascular access modalities (i.e. subclavian vein puncture [SVP], cephalic vein cut-down [CVC], axillary vein puncture [AVP]) used during CIEDs implantations. Methods A systematic review of the literature and network meta-analysis were performed searching Pubmed/MEDLINE databases for relevant articles using the following search strategy, without language restrictions: ((cardiac implantable device) OR (pacemaker) OR (ppm) OR (defibrillator) OR (icd) OR (resynchronization) OR (crt)) AND ((venous access) OR (subclavian) OR (axillary) OR (cephalic)). Randomized and non-randomized studies comparing one or more of the outcomes of interest, between at least two discernible groups (SVP, CVC and AVP), were included in the present analysis and SVP competitive arm was used as the reference group. The primary endpoints were safety outcomes, which included: 1) pneumothorax, 2) pocket haematoma, 3) lead failure, including both acute (dislodgment) and chronic (fracture, subclavian crush syndrome) events, 4) infective complications. Success rate, defined either by successful cannulation of the vein or by successful lead placement was a secondary outcome. Results Forty studies (33, 83% non-randomized) were selected and a total of 166782 patients (median age 69.2 years, 65.2% males) followed up for a median of 18 months (IQR 11-51) were included. Both AVP and CVC showed a significant reduction in the risk of pneumothorax compared to SVP (AVP: OR 0.12, 95% CI 0.05-0.28; CVC: OR 0.18, 95% CI 0.15-0.22) but no significant differences between treatment arms concerning bleedings (AVP: OR 1.11, 95% CI 0.52; 2.37; CVC OR 1.16, 95% CI 0.60; 1.88) or infective complications (AVP: OR 1.00, 95% CI 0.47- 2.14; CVC OR 0.67, 95% CI 0.31-1.44) were observed. Compared to SVP, AVP was significantly superior concerning the risk of lead failure (OR 0.42, 95% CI 0.27-0.67) while CVC showed a nearly statistically significant reduction in risk of lead complications (OR 0.73, 95% CI 0.52-1.02), see figure 1. Success rate did not differ significantly between treatments arms albeit CVC showed a trend towards a higher risk of need for alternate venous access compared to AVP (3.56, 95% CI 0.89-14.21). Conclusions Considering the lower risk of pneumothorax and lead failure, AVP and CVC should be preferred over SVP to achieve venous access during CIEDs implantation taking into account the higher success rates associated with AVP.Figure 1

The Utility of Minimally Invasive Surgery in the Emergency Management of Femoral Hernias: A Systematic Review.

Background: Femoral hernias are a relatively rare type of hernia but have a high complication rate, with a high proportion either presenting as an emergency or requiring emergency management. Minimal access surgery has been shown to be safe, with good results, in an elective setting, but there is little published evidence of its utility in an emergency. Methods: A systematic review was conducted searching PubMed, OVID, Embase, and Cochrane reviews for ((Femoral hernia) AND (laparoscop* OR minimal access OR robotic)) AND (strangulat* OR obstruct* OR incarcerat*). Results: 286 manuscripts were identified of which 33 were relevant. 24 were individual case reports, 3 case series, 4 cohort studies or case control series, and 2 high level reviews of National registers. Conclusion: Minimal access surgery can avoid an unnecessary laparotomy for the assessment of hernial contents, especially via a TAPP approach. Minimal access repair of femoral hernias as an emergency is feasible and can be done safely with results similar to open surgery but good quality evidence is lacking.

A Grain Orientation-Independent Single-Step Saw Damage Gettering/Wet texturing Process for Efficient Silicon Solar Cells.

Improving electrical and optical properties is important in manufacturing high-efficiency solar cells. Previous studies focused on individual gettering and texturing methods to improve solar cell material quality and reduce reflection loss, respectively. This study presents a novel method called saw damage gettering with texturing that effectively combines both methods for multicrystalline silicon (mc-Si) wafers manufactured using the diamond wire sawing (DWS) method. Although mc-Si is not the Si material currently used in photovoltaic products, the applicability of this method using the mc-Si wafers as it contains all grain orientations is demonstrated. It utilizes saw damage sites on the wafer surfaces for gettering metal impurities during annealing. Additionally, it can crystallize amorphous silicon on wafer surfaces generated during the sawing process to allow conventional acid-based wet texturing. This texturing method and annealing for 10min allow for the removal of metal impurities and effectively forms a textured DWS Si wafer. The results show that the open-circuit voltage (ΔVoc =+29mV), short-circuit current density (ΔJsc =+2.5mA cm-2 ), and efficiency (Δη=+2.1%) improved in the p-type passivated emitter and rear cells (p-PERC) manufactured using this novel method, as compared to those in the reference solar cells.

Understanding the role of perceived enjoyment, self-efficacy and system accessibility: digital natives' online learning intentions

PurposeThis research aims to look at how students feel about taking online learning (OL) while studying in higher education institutions (HEIs) using an extended technology acceptance model (TAM). The study looked into the factors that influence students' decisions to use OL, which helps meet their individual needs beyond the confines of the traditional classroom.Design/methodology/approachA study of 284 students from the universities of Gujarat in India was conducted using a self-administered questionnaire. The partial least square-structural equation modelling (PLS-SEM) was used to analyse the study's test results.FindingsThe result of the study confirms that perceived enjoyment (PE) has a fully significant relationship with the behavioural intention to use online learning (IOL), whereas self-efficacy (SE) is partially supported and system accessibility (ACC) has an insignificant impact on the IOL.Research limitations/implicationsThough the study focussed on the TAM to analyse the proposed model, future studies should address other constructs like ICT infrastructure, perceived behavioural control, experience, etc.Originality/valueThis research identified the key variables of students' intention to adapt to OL and offered a path to encourage higher education students to use online education as a classroom alternative. Educators in Indian administrative positions can better facilitate OL adoption amongst their student bodies by developing a keener awareness of students' goals and the factors influencing their views on the topic.

Gettering of epitaxial indium arsenide by the rare earth element holmium

The results of a study of the galvanomagnetic properties of indium arsenide grown by liquid-phase epitaxy are presented. It is shown that the use of the rare earth element holmium in the growth of InAs epitaxial layers makes it possible to reduce the electron concentration by two orders of magnitude to n=2.1·1015 cm-3 at T=77 K. This effect is due to the gettering of shallow background impurities with the formation of their compounds in the melt. With an increase in the holmium content of more than 0.12 mol.% the concentration of current carriers in the material begins to increase, while mobility decreases due to the influence of VAs-Ho donor centers. This method of gettering is promising for obtaining A3B5 materials with a low concentration of current carriers, which are in demand in the optoelectronic industry. Keywords: indium arsenide, rare earth element, Hall coefficient, concentration of current carriers, mobility of current carriers.

Modeling the Customer’s Adaptive Behavior towards Accepting the Technological Change in E-Banking Services: The Moderation Role of Service Accessibility

This study aimed to investigate the moderation role of technology accessibility (ACC) in the relationship between Performance expectancy (PE), Effort expectancy (EE), Social influence (SI), and Facilitating conditions (FC)as a predictor variables and behavioral intention (BI) to adapt with the technological change on the e-banking services.
 A sample of 545 users of e-banking services collected randomly from Sohag, Qina, Luxor, and Aswan cities in Egypt. The authors relied on (Goularte and Zilber 2019; Lichtenstein and Williamson 2006; Paim, Delafrooz, and Taleghani 2014) to measure the study variables. 
 The study findings referred to a significant relationsp between the customer’s adaptive behavior dimensions and accepting the technological change. Only the facilitating conditions –as one of these dimentions- have no effect on the adapting behavior. The findings ,also, supported the  moderating role of ACC in affecting the model interpretation for the customers' BI.
 This study aimed to integrate ACC as one of 4A’s e-banking with the UTAUT on users of e-banking services. The results of the study may help guide the banking mangers in Egypt for improving the level of e-services quality and the readiness to adopt the technological changes of their customers. 
  

Development of a regional solid waste management framework and its application to a prairie province in central Canada

• Waste collection and landfill siting are concurrently optimized at regional level. • Two original performance indicators, ACC and LMI, are proposed and implemented. • Road length is one of the most important optimization parameters in Saskatchewan. • Divisions that share provincial or international borders generally optimized better. • Indigenous communities in border sharing divisions need better landfill siting plan. Landfilling continues to be one of the most popular waste treatment methods in Canada or abroad. NIMBYism has forced waste facilities to be sited further from populated centers, meaning that increases in waste management efficiency result in considerable cost savings. Concurrent optimization of waste collection and disposal siting on a regional scale is of practical importance. This study combines collection route optimization and landfill siting using GIS methods to design a regional waste management system in Saskatchewan, Canada. Two original performance indicators are proposed based on route optimization and landfill siting, namely the accessibility (ACC) and Landfill Minimization Index (LMI). The result suggest that the accessibility was able to be improved by between 15.4 and 794.7%, and the optimization methods was always effective in providing higher resident accessibility. Improvements in the LMI yielded less improvement, ranging from -13.9% to +422.2%. Correlation analysis showed that road length is a key optimization parameter. This finding is important to Indigenous communities who suffer from a lack of intensified road network. Divisions that share provincial or international borders generally have higher improvements in ACC and LMI. Strategic placement of landfills and road networks are key to improve waste management system efficiency in Saskatchewan.

Transbrachial Access Site Complications in Endovascular Interventions: A Systematic Review of the Literature.

The transfemoral approach (TFA) or transradial approach (TRA) serves as the primary technique for most endovascular cases; however, the transbrachial (TBA) route is an alternative access site used when TFA and TRA are contraindicated. Although TBA has advantages over TRA, such as the ability to accommodate large guide catheters and devices, there is some apprehension in implementing TBA due to perceived access site complication rates. This article aims to glean the rate of access site complication from current literature.Relevant studies were identified using the following search terms: ((access site complications) AND ((endovascular AND brachial) OR (percutaneous brachial access) OR (brachial))) OR (endovascular AND (percutaneous brachial access)); endovascular + brachial artery; endovascular + brachial artery + access site; and endovascular + brachial artery + access site complications. Articles published after 2008 addressing major complication rates from percutaneous TBA interventions were included.Fifteen studies out of 992 total articles met the inclusion criteria. The major access site complication rate was 75/1,424 (5.27%). Patients who underwent hemostasis with a vascular closure device (VCD) had a major complication rate of 13/309 (4.21%) compared to a major complication rate of 65/1122 (5.79%) for patients who underwent hemostasis with manual compression (MC).The major access site complication rate associated with TBA was 5.27%, which is relatively high compared to the complication rate in TFA or TRA. More prospective trials are needed to fully understand the access site complication rate in TBA interventions.

The Role of Online Experience in the Relationship Between Service Convenience and Future Purchase Intentions

This article investigates the effects of online convenience and shopping experience on consumer satisfaction and future purchase decisions by applying a different view to explain the customers’ increasing experience with online shopping in the Chinese growing market. Data from 226 Chinese consumers used to buy online are used to analyze the proposed research model through Partial Least Squares Structural Path Modeling. The findings show that the intention to purchase is enhanced by customer satisfaction and shopping experiences and that satisfaction plays a mediating role in these relationships. Additionally, the results show that search and post-possession dimensions have the most influence on online shopping convenience. In contrast, access (ACC), transaction (TRA), and possession (POS) convenience have an indirect negative impact on future purchase intention. The findings offer actionable guidance to online retailers wanting to enhance customer satisfaction and promote future purchase intentions by helping retailers who are doing business or planning to do business online in China. Offering additional suggestions on how to foster online satisfaction, the study’s conclusions help improve the effectiveness of e-commerce strategy. The current study also extends previous work on service convenience by validating the impact of online shopping convenience (SCV) on customer satisfaction and repurchase intention.

Improving usability benchmarking for the eHealth domain: The development of the eHealth UsaBility Benchmarking instrument (HUBBI).

BackgroundCurrently, most usability benchmarking tools used within the eHealth domain are based on re-classifications of old usability frameworks or generic usability surveys. This makes them outdated and not well suited for the eHealth domain. Recently, a new ontology of usability factors was developed for the eHealth domain. It consists of eight categories: Basic System Performance (BSP), Task-Technology Fit (TTF), Accessibility (ACC), Interface Design (ID), Navigation & Structure (NS), Information & Terminology (IT), Guidance & Support (GS) and Satisfaction (SAT).ObjectiveThe goal of this study is to develop a new usability benchmarking tool for eHealth, the eHealth UsaBility Benchmarking Instrument (HUBBI), that is based on a new ontology of usability factors for eHealth.MethodsFirst, a large item pool was generated containing 66 items. Then, an online usability test was conducted, using the case study of a Dutch website for general health advice. Participants had to perform three tasks on the website, after which they completed the HUBBI. Using Partial Least Squares Structural Equation Modelling (PLS-SEM), we identified the items that assess each factor best and that, together, make up the HUBBI.ResultsA total of 148 persons participated. Our selection of items resulted in a shortened version of the HUBBI, containing 18 items. The category Accessibility is not included in the final version, due to the wide range of eHealth services and their heterogeneous populations. This creates a constantly different role of Accessibility, which is a problem for a uniform benchmarking tool.,ConclusionsThe HUBBI is a new and comprehensive usability benchmarking tool for the eHealth domain. It assesses usability on seven domains (BSP, TTF, ID, NS, IT, GS, SAT) in which a score per domain is generated. This can help eHealth developers to quickly determine which areas of the eHealth system’s usability need to be optimized.

Female students have been found as the more vulnerable when it comes about eating behaviour. N=211 in this study reported their hedonic hunger level using the Power of Food scale. The design of this study was quantitative descriptive. Data was analysed using descriptive technique. The result show that 37% participants were categorized as low in hedonic hunger, 37 % moderate, and 31.3% high. We conclude that this finding can be used as basis for healthy eating intervention that emphasizing the psychological aspect of eating.

Traduzione audiovisiva e accessibilità. Riflessioni a partire da alcuni conflitti epistemici in ambito formativo

Over the past few years, the question of accessibility has become a central driver in Audiovisual Translation and, through this area, has spread into the field of Translation Studies. However, the ways in which accessibility is discussed and framed within Audiovisual Translation are not neutral. Following a short introduction to threshold concepts theory, the results of an investigation on threshold concepts conducted with a group of postgraduate Audiovisual Translation students are discussed. I then elaborate on some of their replies, which highlight a series of epistemic conflicts. I discuss how those conflicts may be related to the different ways that accessibility is introduced and discussed in AVT education. In the conclusion, I briefly discuss how such conflicts are connected to different ways of interpreting the claim that (audiovisual) translation is accessibility , and I argue in favour of a weak interpretation of said claim.
