User-Centric Conversational Recommendation: Adapting the Need of User with Large Language Models

Conversational recommender systems (CRS) promise to provide a more natural user experience for exploring and discovering items of interest through ongoing conversation. However, effectively modeling and adapting to users’ complex and changing preferences remains challenging. This research develops user-centric methods that focus on understanding and adapting to users throughout conversations to provide the most helpful recommendations. First, a graph-based Conversational Path Reasoning (CPR) framework is proposed that represents dialogs as interactive reasoning over a knowledge graph to capture nuanced user interests and explain recommendations. To further enhance relationship modeling, graph neural networks are incorporated for improved representation learning. Next, to address uncertainty in user needs, the Vague Preference Multi-round Conversational Recommendation (VPMCR) scenario and matching Adaptive Vague Preference Policy Learning (AVPPL) solution are presented using reinforcement learning to tailor recommendations to evolving preferences. Finally, opportunities to leverage large language models are discussed to further advance user experiences via advanced user modeling, policy learning, and response generation. Overall, this research focuses on designing conversational recommender systems that continuously understand and adapt to users’ ambiguous, complex and changing needs during natural conversations.
Sequential Recommendation Models: A Graph-based Perspective

Recommender systems (RS) traditionally leverage the users’ rich interaction data with the system, but ignore the sequential dependency of items. Sequential recommender systems aim to predict the next item the user will interact with (e.g., click on, purchase, or listen to) based on the preceding interactions of the user with the system. Current state-of-the-art approaches focus on transformer-based architectures and graph neural networks. Specifically, graph-based modeling of sequences has been shown to be state-of-the-art by introducing a structured, inductive bias into the recommendation learning framework. In this work, we outline our research into designing novel graph-based methods for sequential recommendation.
Saffo in Sicilia

“May I write words more naked than flesh, stronger than bone, more resilient than sinew, more sensitive than nerve” (Sappho): although only one single, 28-line intact poem and in total 650 out of an estimated 10,000 lines of her poetry survive in the written form today, Sappho's work has certainly proven to be “stronger than bone.” Its resilience has endured for over two millennia.In his Saffo in Sicilia (Sappho in Sicily), Francesco Di Vincenzo masterfully explores the many intersections of his native Sicily with the Greek poet, crafting a narrative that, while starting from an accurate and perceptive analysis of the fragments (and especially those pertaining to the years of her Sicilian exile), expands to provide many avenues of interpretation of this quasi-mythical figure, one that keeps mutating but still permeates Western poetry.Through life anecdotes, such as those regarding the birth in Syracuse of her beloved daughter Cleis, punctual historical references, and convincing etymological interpretations, Di Vincenzo recreates a living figure and succeeds in his goal of “interpreting the motions of the poet's soul” (“sentire i moti dell'anima della poetessa” [80]). The result is a continually fascinating portrait both for scholars and general readers, who may use it as an introduction to her work and life.In this short but unforgettable volume, Sappho's figure emerges as both all-powerful (“a character whose merits, both artistic and social, and whose fame continued to shine in the centuries following her death” [26]) and everchanging, unstable to the point of becoming a true archetype of women's poetry. In this latter sense, Di Vincenzo includes different avenues of interpretation, from the most-commonly passed-on biographical details to a keen awareness that Sappho as we know her today is the result of centuries of re-interpretation and mutation. In this sense, the brief chapter titled “Saffo 1 e 2” (Sappho 1 and 2) presents a convincing hypothesis by which the poet may in fact be the conglomeration of two separate figures, living about 250 years apart from each other in the sixth and fourth centuries BCE, respectively: one born, as commonly known, on Lesbos, and the second a native Sicilian.How, then, wonders Di Vincenzo in the final pages of his book, to interpret Sappho? Earlier he made clear that his pages are not meant to give answers but rather to create new questions (“[ . . . ] queste pagine non vogliono dare risposte ma fare nascere interrogativi” [58]). In his final lines, citing Michel Foucault, Di Vincenzo urges us to create absolute truth out of chaos. By doing so, we can make certain that Sappho's words, her life in its many possible variations, her influence on Sicily and Italy, and her everlasting power across the world will remain with us forever.
Meningkatkan Aktifitas dan Keterampilan Interaksi Transaksional Lisan (Speaking) Melalui Penerapan Model Role Play pada Materi Nama Hari, Bulan, dan Waktu bagi Siswa Kelas VII

This research was conducted because the value of English was far from the specified Madrasah Maximum Completeness Criteria (KKM). Against the background of the low value of the English language, this research was conducted with the aim of increasing the activity of English speaking transactional interaction skills on the material names of days, months and times by using the role play model. This research was conducted from September to November 2017, taking place in class VII-8 MTs. Negeri 1 Mataram, Mataram City. This type of research is Classroom Action Research (CAR) with two cycles consisting of two meetings in one cycle, each cycle consisting of planning, implementing, observing and reflecting. Data collection techniques and tools in this study used descriptive analysis techniques for data in the form of student performance scores and observation sheets. The results showed that with the activity role play model and students' oral transactional interaction skills increased, that is, from the results of cycle I to Cycle II there was an increase where in cycle I the number of students who received a complete score was 23 students or 67.65%, the score was incomplete on cycle I was 11 students or 32.35%, while in cycle II there was an increase in the pass score, namely, to 23 students or 85.29% there was an increase of 17.64%. It was concluded that the role play model can improve English spoken transactional interaction skills.
Meningkatkan Prestasi Belajar Siswa dengan Menggunakan Media Powerpoint pada Pelajaran Ilmu Pengetahuan Sosial

This study aims to improve student achievement during online learning in social studies lessons using Powerpoint media at SMP Negeri 2 Telukjambe Timur, Karawang Regency, West Java Province. This research was conducted in class VIIA SMP Negeri 2 Telukjambe Timur. This research was carried out in two cycles, each cycle consisting of two online meetings. The 1st cycle was held from 04 to 11 August 2020, and the 2nd cycle was held from 18 to 25 August 2020. Qualitative data collection techniques were obtained from observing students' attendance and activeness in learning. The quantitative data that records students' absorption of learning is collected through the implementation of written evaluations with the help of essay questions. Based on the results of the pre-test, it was stated that out of 41 students there were around 68.29% or 28 students who had not finished their studies, while 34.71% or 13 students had completed their studies. When viewed from the achievement of teaching and learning, out of 41 students 68.29% or around 25 grades were still below the teaching and learning process, 19.51% or 8 students had achieved the teaching learning process, and 12.20% or 5 students scored above the teaching learning process. So that from the results of the social studies subject pretest the results can be categorized as still very low. In cycle 1 it can be stated that out of 41 students there were around 19.51% or 8 students who had not completed their studies, while 80.49% or 33 students had completed their studies. When viewed from the achievement of teaching and learning, out of 41 students 19.51% or around 8 grades were still below the teaching and learning process, 60.98% or 25 students had achieved the teaching and learning process, and 19.51% or 8 students scored above the teaching learning process. So that from the results of cycle 1 regarding social interaction material the results can be categorized as low. In the 2nd cycle all students can master this material as proven by 41 students 100% or 41 students have completed their studies. If we look at the achievement of the teaching and learning process, out of 41 students 43.90% or 18 students have achieved the teaching and learning process, and 56.10% or 23 students scored above the teaching and learning process. In this case the treatment in cycle 2 can improve student achievement in social studies subjects which are in the high category.

The data collection techniques used in this study were: documentation, observation questionnaires, and interviews. Students' interest in continuing their studies to higher education in Class XII Idhata Senior High School Banjarmasin for the Academic Year 2019/2020, is classified as "not good" because the largest number of scores is in the TS category, which is 31.74%, which is between 0%-40%.
Pengembangan LKS Berbasis VAK (Visualization Auditory Kinestetic) sebagai Bahan Ajar Alternatif Siswa SMA

One of the problems faced by students is that the teaching materials in the form of worksheets used still have shortcomings, namely they are still conventional or have not led to certain learning models so that students have difficulty understanding learning materials. For this reason, it is necessary to develop teaching materials in the form of LKS based on VAK (Visualization Auditory Kinesthetic) which is intended to make it easier for students to understand the lesson. The aims of this research are: 1) to develop VAK-based worksheets as alternative teaching materials for high school students; 2) produce worksheets that are developed based on VAK that are appropriate as alternative teaching materials for high school students; and 3) determine the readability of the LKS developed based on VAK as an alternative teaching material for high school students. This type of research is a development research with a 4-D model design consisting of four stages, namely define, design, develop, and disseminate. The results of developing Student Worksheets that have been compiled are then validated by 3 validators namely content, display, and language experts using an expert validation sheet instrument and a readability test using a questionnaire sheet instrument to the reader. Based on the results of the research on the development of VAK-based LKS, it is feasible to use with a validity level of 3.88 with a good category, a student readability test questionnaire with a score of 3.51 with a good readability category. So it can be concluded that the development of VAK-based worksheets with good categories can be used as alternative teaching materials for high school students.

Based on the results of initial observations that have been carried out at Teuku Umar Junior High School Surabaya, it was found a problem that motivation and learning outcomes are still in the medium category and still need to be improved, as evidenced by the results of interviews with biology subject teachers and the results of odd semester tests there are still students who the value is below the KKM. The purpose of this study is to describe students' learning motivation by applying the question student have learning strategy with the wheel of fortune technique and explain the effect of the question student have learning strategy with the wheel of fortune technique on the cognitive learning outcomes of seventh grade students of Teuku Umar Middle School Surabaya in the 2019/2020 school year. This type of research is a quasi-experimental research design with posttest-only nonequivalent control group design. The population in this study were all seventh grade students of Teuku Umar Junior High School Surabaya with a research sample of VIIA grade students with 19 students as the experimental class and VIIB class students with 19 students as the control class, which were taken using purposive sampling technique. The instruments used in this study were observation sheets, questionnaires and tests. There are two ways to analyze the data in this study, namely descriptively for students' learning motivation and hypothesis testing with t-test for students' cognitive learning outcomes. The results showed that the percentage of students' learning motivation in the experimental class was 71.7% in the good category and the control class was 69.9% in the good category. While the average cognitive learning outcomes of students in the experimental class is 70.26 and in the control class is 60.4. Analysis of learning outcomes with t-test at a significant level of 5% obtained tcount of 3.56 while the value of ttable with dk 36 of 2.04. This means that tcount ≥ ttable (3.56 ≥ 2.04). Thus, it can be concluded that there is an effect of the question student have learning strategy with the wheel of fortune technique on students' cognitive learning outcomes.

Perceptions of the influence of a mobile phone-based messaging platform on caregiver ECD knowledge, attitudes and practices: a qualitative exploration in an informal settlement in Nairobi

Abstract Background Programs supporting initiatives for children younger than three years are inadequate and not accessible to many families, particularly in resource-limited settings. Many primary caregivers have little knowledge on how to monitor the development of their children or the importance of engaging children in stimulative activities during the course of early development. Health system limitations make it difficult for health workers to educate and demonstrate stimulative engagement to caregivers. The massive use of technology can be used to facilitate access to growth and development programs for children. We developed and implemented a mobile phone technology to help caregivers monitor and stimulate their children’s development in real-time. This study explored the influence that this intervention had on the caregivers’ early child development (ECD) knowledge, attitudes and practices. Methods In this qualitative cross-sectional study, we conducted interviews through eight (8) focus group discussions, three (3) key informant interviews and 9 indepth interviews among a total of 111 participants including primary caregivers (n = 87), community health volunteers (CHVs) (n = 21) health managers and workers (n = 3) to determine their attitudes and experience with the intervention with regards to improving their KAP. Interviews were audio-recorded, transcribed, and analyzed thematically. Results Caregivers and CHVs reported that the intervention had provided them with new knowledge that positively influenced their ECD caregiving attitudes and practices. CHVs and health workers and managers reported that the intervention had provided caregivers with confidence in caring for their children while increasing their knowledge on how to monitor and stimulate their children’s development. Conclusion Mobile phone technology can be effectively used to enhance caregivers’ knowledge of ECD and enable them to monitor and support their children’s development in real-time. Trial registration The trial was registered with the Pan African Clinical Trial Registry ( www.pactr.org ) database (ID number: PACTR201905787868050 Date: 6/05/2019.
THE ART OF HUMAN PARTICIPATION AGAINST AERTIFICAL INTELLIGENCE WITH GEOSPATIAL INFORMATION SYSTEM IN THE TOURISM INDUSTRY

The development of the tourism industry is very important for developing countries that are facing problems such as high unemployment rates, a distorted international image, limited foreign exchange resources, and a single-product economy, especially oil. Investing in this industry, which is considered a human art, is measured based on the public health of each country and will be the basis for tourists' decisions as a tourist destination. The purpose of this research is to investigate public decision-making in different temporal and spatial conditions based on psychological events. This fact is a must for the tourism industry of a society that must be managed. Then we challenge the artificial intelligence to realize that, entrusting rational decisions can replace human thinking. The methods of this study are based on NPGIS software, where decision-making methods and statistical sampling are determined together. Therefore, the study methods and a case example are presented just to know. Because it has transnational applications. The results show that: entrusting spatial decisions (space-time-place) to artificial intelligence is only possible if we consider the consequences. Finally, time and the criteria related to it show their key role. The fusion of space sciences with the tourism industry can be related to all the industrial and money-making sectors of a country. It seems easy to make an AI that works correctly once a day, but if it tries to do the same thing several times in a day, it becomes more prone to errors.
PERFORMANCE ANALYSIS OF PRODUCTION UNITS FOLLOWING THEIR REINTRODUCTION IN SELECTED SECONDARY SCHOOLS OF LUSAKA

Production units were a common feature in most schools during the United Independence Party (UNIP) Government. They were an important component of preparing learners for independent living as well as a way of making schools a second home for learners where learners could learn and eat. This study assessed the performance of Production Units in selected secondary schools in Lusaka District. The objectives of the study were; to establish how the Production Units were managed in selected schools in Lusaka District and to explore the challenges that were affecting the performance of Production Units in schools. A qualitative research approach and a descriptive design were adopted. Eighteen (18) participants in charge production units in the three selected schools were purposively selected and involved in the study. The composition of sample was Three (03) Head- teachers; Three (03) Heads of Departments; and Six (06) Science Teachers; and Six (06) General Workers, all members that were purposively selected by virtue of their involvement in production unit. The findings established that that schools had established structures that guided the management of production units. It was further established that decisions were made democratically on how production units should run in each school sampled in the study. In terms of the performance, it was revealed that the units were adding value to schools through the activities undertaken under production units. Some challenges were identified in terms of how the production units were operating in schools. These included: shortage of land, poor planning in terms of timing of activities to do with production units, lack of proper training, lack of transport and market, and inadequate financial resources for expanding production units’ activities. Arising from the findings of the study, the following recommendations were made: workers under production units should be trained; schools to develop marketing strategies through working with supermarkets, hotels and lodges. Also, land to be secured through the help of Ministry of General Education and Ministry of Lands for schools to expand their ventures.
