Diversification-oriented accuracy prediction in recommender systems

Tremendous amount of data generated by e-commerce users on items (e.g., purchase or rating history), sets some key challenges for the online knowledge discovery scheme. Recommendation systems are an important element of the digital marketplace such as e-stores and service providers that use the generated information to discover preferred products of the consumers. Developing an effective recommender system that produces diverse suggestions without compromising the precision of the customised list is challenging for online systems. This paper aims at diversifying recommendation by integrating graph-based algorithm supported with significant nearest neighbour strategy for enhancing recommendation precision. The experimental efficacy on the 100K dataset of MovieLens shows that the proposed hybrid model has a strong coverage and superior efficiency in product recommendations.

ANALISIS FAKTOR-FAKTOR YANG MEMENGARUHI TINGKAT STRESS MAHASISWA STATISTIKA UII TERHADAP PEMBELAJARAN DARING SELAMA PANDEMI COVID-19

Covid-19 is a group of viruses that can spread very quickly, so every country must act to reduce the spread of Covid-19. The Ministry of Health of the Republic of Indonesia applies Health protocols to avoid crowds. It also leads to activities such as work and also studying from home to avoid physical contact. The Ministry of Education and Culture issued a circular regarding the implementation of online learning to spread Covid-19. Likewise, UII applies online knowledge. Changes in the learning system that are sudden and continue today can affect students' physical and mental health. Online learning and piles of assignments lead to increased anxiety and stress levels, even more so during the Covid-19 pandemic. This study aims to determine the factors that influence students' stress levels towards online learning. The method used is a survey method with a descriptive approach. Statistical data analysis used validity and reliability tests, univariate, bivariate, and multivariate. The results of the truth and reliability test showed that the Instrumen on DASS-42 was valid and reliable. Bivariate analysis with chi-square test found that there were differences in stress levels with age and semester. Multivariate analysis using an ordinal logistic regression test concluded that the factors that influence stress levels are age and male sex

USE OF ONLINE INFORMATION BY THE UNIVERSITY RESEARCH STUDENTS AND ITS EFFECT ON THE QUALITY OF RESEARCH DISTRICT LAHORE

Academics, especially research students, are increasingly using online data assets (OIRs). According to statistics, MS students and college and university graduates both decide how frequently they use social networking platforms. The file also reveals that one of the most popular reasons college students apply to University Research University College is a "passion for evaluating data." Online reporting resources have appeared since the inception of the Internet, and these resources are becoming more and more well-liked among Internet users, particularly academics, researchers, and college students. These online knowledge sources have positive influence on Pakistan's study lifestyle as well. As a result, Pakistan has a more suited research culture. To do this, consider reading record ownership forms online; learn about the OIRs' offer and amount of importance; access to styles; access to methods; and the applicability of various types. With the study's goals in mind, quantitative study methods were used, and questionnaires were created to gather information from the respondents. A total of 18 people (60%) and 12 public universities (40 participants) took part in this poll. Out of 200 university studies, 16 (8% of the total) are from public institutions, and 80 (forty
 %) are from non-public universities in the area. 104 with an average pattern size (fifty-two present). In terms of gender ratio, 94 (47%) of the respondents were male and 146 (73%) were female, which is a fair response. Facts took on a numerical form and included scales for nominal, ordinal, programming language, and length ratio. More statistical resources are available to research undergraduates at public research universities than at private institutions. They needed more possessions and more access to options for the investigation's direction and craft. Standard because, at this time, university students studying humanities, social sciences, and technology most frequently access patterns through search engines like yahoo and google.

Comparison of Russian and Kazakhstan proctoring systems

The article analyzes the problems faced by teachers in the context of the forced transition to distance learning in connection with the COVID-19 pandemic, when interaction with students was carried out only using information technologies. There are problems of organizing and conducting exams in remote access: the difficulties of identifying students, the use of proctoring technologies. The main problem of distance learning is objective assessment of knowledge. Online proctoring systems are one way to discourage student academic fraud. The article discusses the possibilities and problems of using the online proctoring system for online knowledge control. The possibility and feasibility of using proctoring technology in remote monitoring of the progress of university students, as a tool for personal identification are analyzed. Varieties of the proctoring procedure, classification of technologies based on the products of ProctorEdu, Examus, Oqylyq, Aero, Oes are considered, as well as the advantages and disadvantages of the proctoring system. The article notes that the Kazakhstani proctoring systems Oqylyq, Aero, Oes are not inferior to the Russian proctoring systems ProctorEdu, Examus. On the basis of the analysis of proctoring systems, the validity of its application was confirmed from the point of view of efficiency in terms of such indicators as the reliability of identity verification, reduction of time and material costs.

Impact of Online Knowledge and Skills Learning on Millennial Learners Within Emergency Medicine: A Retrospective Data Review.

Background: Emergency Medicine didactic teaching has traditionally been delivered through face-to-face (F2F) lectures. However, during the pandemic of COVID-19, the didactic teaching was switched to online through using Microsoft Teams. The aim of this study was to assess the impact of online learning in the knowledge and skills acquisition of millennial learners based within emergency medicine.Methodology: This was a retrospective review of assessment data. Over a period of 10 months (August 2019 to June 2020), each resident was exposed to traditional F2F teaching for a period of four months and then online teaching in a crossover manner. After each method, there were two types of assessments, multiple-choice questions (MCQs) and computer-based objective structured clinical examination (OSCE). A total of 20 MCQs with one correct answer, totaling 20 marks, and 20 OSCEs consisting of an image or a video with five options, each option carrying one mark, totaling 100 marks were used at each assessment point. A student t-test was used to compare the two groups of results.Results: The total number of participants was 49 (n=49). All residents belonged to the millennial generation. Fourteen were female and 35 were male. The mean MCQ 1 score after F2F teaching was 12.16 (SD=1.688), whilst the mean MCQ 2 score after online teaching was 13.40 (SD=1.861). The mean computer-based OSCE 1 score after F2F teaching was 64.45 (SD=5.895), whilst the mean OSCE 2 score after online teaching was 65.57 (SD=5.969). Ten out of 49 students (20.4%) failed the MCQ exam after F2F teaching, whilst 6/49 students (12.2%) failed the MCQ test after online teaching. Seven out of 49 students (14.3%) failed the OSCE exam after F2F teaching, while six out of 49 students (12.2%) failed the OSCE exam after online teaching. There was a statistically significant improvement in the MCQ score after online teaching as compared to F2F teaching (P-value 0.0003), whilst there was no statistically significant change in the OSCE between the two-teaching methods (P-value 0.3513).Conclusion: Both F2F and online teaching methods resulted in a significant improvement in the knowledge and skills of emergency medicine residents. Online education resulted in a statistically significant improvement of MCQ score as compared to F2F teaching. The difference in MCQ score may be due to millennial learners, who traditionally benefit proportionately more from self-learning that is primarily online.

Turning lurkers into innovation agents: An interactionist perspective of self-determinant theory

Despite the general negative conception about lurkers in online knowledge-sharing practices, there is a growing body of literature that suggests the bright side of lurking behavior, termed as active lurking. Building upon the self-determination theory, this research aims to examine the individual and organizational aspects that may influence individual employee’s motivation to engage in active lurking behaviors. In a study of 200 employees in the banking sector, we demonstrate support for the relationships among perceived importance of knowledge, perceived negative reputation influence, active lurking behavior, knowledge collecting and individual innovative capability in both public and private companies. We also find that organizational culture plays an important role as moderating variable. This research adds to the knowledge sharing literature by showing that the interaction between individual and organizational aspects can turn lurkers into active participants in organizational online knowledge sharing and increase their innovative capability.

A qualitative assessment of the impact of smart homes and environmentally beneficial technologies on the UK 2050 net-zero carbon emission target

PurposeThere are 29 million homes in the UK, accounting for 14% of the UK's energy consumption. This is given that UK has one of the highest water and energy demands in Europe which needs to be addressed according to the Committee on Climate Change (CCC). Smart homes technology holds a current perception that it is principally used by “tech-savvy” users with larger budgets. However, smart home technology can be used to control water, heat and energy in the entire house. This paper investigates how smart home technology could be effectively utilised to aid the UK government in meeting climate change targets and to mitigate the environmental impact of a home in use towards reducing carbon emissions.Design/methodology/approachBoth primary and secondary data were sought to gain insight into the research problem. An epistemological approach to this research is to use interpretivism to analyse data gathered via a semi-structured survey. Two groups of participants were approached: (1) professionals who are deemed knowledgeable about smart home development and implementation and (2) users of smart home technology. A variety of open-ended questions were formulated, allowing participants to elaborate by exploring issues and providing detailed qualitative responses based on their experience in this area which were interpreted quantitatively for clearer analysis.FindingsWith fossil fuel reserves depleting, there is an urgency for renewable, low carbon energy sources to reduce the 5 tonnes annual carbon emissions from a UK household. This requires a multi-faceted and a multimethod approach, relying on the involvement of both the general public and the government in order to be effective. By advancing energy grids to make them more efficient and reliable, concomitant necessitates a drastic change in the way of life and philosophy of homeowners when contemplating a reduction of carbon emissions. If both parties are able to do so, the UK is more likely to reach its 2050 net-zero carbon goal. The presence of a smart meter within the household is equally pivotal. It has a positive effect of reducing the amount of carbon emissions and hence more need to be installed.Research limitations/implicationsFurther research is needed using a larger study sample to achieve more accurate and acceptable generalisations about any future course of action. Further investigation on the specifics of smart technology within the UK household is also needed to reduce the energy consumption in order to meet net-zero carbon 2050 targets due to failures of legislation.Practical implicationsFor smart homes manufacturers and suppliers, more emphasis should be placed to enhance compatibility and interoperability of appliances and devices using different platform and creating more user's friendly manuals supported by step-by-step visual to support homeowners in the light of the wealth of knowledge base generated over the past few years. For homeowners, more emphasis should be placed on creating online knowledge management platform easily accessible which provide virtual support and technical advice to home owners to deal with any operational and technical issues or IT glitches. Developing technical design online platform for built environment professionals on incorporating smart sensors and environmentally beneficial technology during early design and construction stages towards achieving low to zero carbon homes.Originality/valueThis paper bridges a significant gap in the body of knowledge in term of its scope, theoretical validity and practical applicability, highlighting the impact of using smart home technology on the environment. It provides an insight into how the UK government could utilise smart home technology in order to reduce its carbon emission by identifying the potential link between using smart home technology and environmental sustainability in tackling and mitigating climate change. The findings can be applied to other building types and has the potential to employ aspects of smart home technology in order to manage energy and water usage including but not limited to healthcare, commercial and industrial buildings.

Acceptability of an online training program for dementia caregivers: Results from a mixed‐methods pilot randomized controlled trial

AbstractBackgroundiSupport is an online knowledge and skills training program developed by the World Health Organization to prevent and/or minimize caregiving‐associated health problems. iSupport was culturally adapted to Portugal.MethodA mixed‐methods two arm RCT was carried. Participants were recruited through the Alzheimer’s Association. Inclusion criteria are being a non‐paid caregiver; for at least six months; experiencing a clinically relevant level of burden (≥ 21 on ZBI) or depression or anxiety symptoms (≥ 8 on HADS). Eligible participants were randomized to either iSupport‐Portugal or the control arm (e‐book). Repeated measurements were collected at baseline, three (T1) and six months after baseline. Semi‐structured interviews were conducted. Usage data until T1 was extracted from iSupport’s platform. A content analysis was performed for interview data.ResultsForty‐two participants were allocated to the intervention (n=21) and control (n=21) arms. Caregivers in the intervention arm are mostly female (81%), middle‐aged (M 49 years) and highly educated (M 15.8 years of schooling). Most (81%) are children of the person with dementia, provide long‐term (Mdn 3 years) and intensive care (Mdn 29 hrs/week). Scores on ZBI (Mdn 38) and HADS‐anxiety (Mdn 12) suggest moderate to high levels of burden and anxiety. Positive attitudes towards online psychoeducation were revealed (Mdn 24 on OPI‐BAS scale). Twelve caregivers were interviewed, including dropouts. At T1, 85.7% of participants have used the program; 38.9% discontinued its use within two weeks, 66.7% within ten. On average, iSupport was accessed 8 times and 12.5 lessons were visited (in 23). One‐time‐only visitors printed the lessons (n=2); offline use is possible. Lessons on communication and shared decision making were the most visited (>90%). The qualitative data informs on the motivations and deterrents to use iSupport, usage styles, and perceived results.ConclusionA moderate acceptability of iSupport‐Portugal is suggested and might be improved with minor content and interface adjustments. Despite heterogeneous usage patterns, iSupport was mostly used intensively and during a few weeks. Conducting a re‐assessment (T1) earlier might be adequate. When nationally releasing iSupport, research on usage data must consider potential biases from unknown offline use. This pilot may inform improvements on iSupport country‐specific versions.

Дистанційне/змішане навчання: особливості сприйняття студентською молоддю

The aim of the study is to determine the attitude of higher education students of medical and physical and mathematical profile to distance / mixed learning (DL/ML) and its impact on their academic success. An anonymous online survey of 799 students (medical and physical and mathematical profile of study). The issues concerned various aspects of the organization of DL/ML. The obtained data were processed in IBM SPSS Statistics 22. It was found that half of medical and physical and mathematical students are positive about the use of DL/ML in the future (52.19%). One third of the respondents strongly oppose the continuation of distance education (34.79%). Moreover, students of physics and mathematics more often (p<0.05) determined the absence of differences between these forms and were more likely to return to the classical system of education. Applicants for physics and mathematics noted that virtual laboratory work is possible in the future (p<0.05). Medical students were more in favor of online knowledge control (p<0.01). Almost 70% of students in both groups noted that during DL/ML there was more free time, 1/3 of students affirm that their academic performance has improved and in general DL/ML did not affect on the desire to study, and a quarter of respondents noted that they used a part of free time at DL/ML for self-study, attending numerous scientific forums. According to the results of the survey, 80% of both groups had free time due to the exclusion of travel time. The study also showed that the effectiveness of training in a third of respondents was negatively affected by lack of factual information, lack of communication with classmates and teachers, and insufficient concentration, especially in the group of physical and mathematical profiles of study (p<0.05).

Don't throw the student out with the bathwater: online assessment strategies your class won't hate

STEM educators have taken on a new and radically different reality: that students will have access to online tools and online knowledge as they undergo assessment. Students may look up facts that are easily available online, employ online tools and also employ paid services to cheat. The first wave of novel assessment strategies devised in response to this new reality was online invigilation measures that were often either ineffective or widely hated by students. This paper considers two frameworks for effective online assessment in the modern era: a framework for question design in STEM and a framework for the structure of assessment. The framework for question design discusses methods to discourage the use of online tools and calculators to simply obtain answers and methods to detect contract cheating. The framework for assessment structure discourages cheating while managing to increase student satisfaction and engagement with content: we present a case study from a cohort of 113 first-year university students of adapted assessment strategies with no identified paid cheating, well-differentiated student results and large-scale positive student feedback. Our key contribution is to identify simple and effective steps to assess students fairly in an online environment, without empowering or motivating them to cheat.

Leveraging enterprise social network technology: understanding the roles of compatibility and intrinsic motivation

PurposeThis study explores the factors influencing the value of enterprise social media (ESM) from the perspective of compatibility. Establishing a theoretical model based on compatibility theory, the authors examine the effects of two dimensions of compatibility and the mediating effects of employees' intrinsic motivations. ESM is an important tool that helps companies to enhance knowledge sharing and cross-department collaboration. Thus, it is important to understand factors that can facilitate the role of ESM in improving enterprise operating performance.Design/methodology/approachThe authors conducted a survey among 353 users of a leading ESM platform and empirically investigated how compatibility influences ESM value through employees' intrinsic motivations. Structural equation modeling (SEM) was applied to study the relationship among compatibility, employees' intrinsic motivations and ESM value.FindingsThe empirical research results indicate that compatibility of self-interest with group interest influences the value of ESM, and intrinsic motivations toward collaboration and toward knowledge management partially mediate the effects of the two dimensions of compatibility on ESM value.Research limitations/implicationsFirst, the empirical analysis relies on data from surveying employees of Chinese companies. Therefore, one direction for future research is to reexamine the model using data from other countries. Second, the effects of compatibility identified in the study may vary among different ESM platforms. In addition, the findings may change for organizations having different sizes.Practical implicationsThis finding suggests that managers should pay close attention to potential conflicts of interest when implementing ESM to enhance group communication and collaboration. This study also highlights the importance of compatibility of new working processes with experience in practice. In addition, intrinsic motivations towards both cooperation and knowledge management in ESM are important factors influencing the value creation of ESM. Therefore, to cultivate employees' intrinsic motivation, managers and organizations need to facilitate the formation of a collaborative atmosphere and habits of cooperative adoption.Originality/valueAlthough previous studies show that compatibility is a strong belief salient to technology acceptance and continuance usage behavior, the operational definition of compatibility developed by prior studies has generally been limited to the technology perspective and the individual level. However, the primary benefit of ESM is enabling online team collaboration and knowledge sharing across various departments. Thus, the level of compatibility between employees' self-interests and group interests may influence their intrinsic motivations toward ESM usage. From this perspective of individual–group interest conflicts, the authors propose a conceptual research model based on the theory of compatibility in innovation diffusion.

Online knowledge distillation with elastic peer

Knowledge distillation is a highly effective method for transferring knowledge from a cumbersome teacher network to a lightweight student network. However, teacher networks are not always available. An alternative method called online knowledge distillation, which applies a group of peer networks to learn collaboratively with each other, has been proposed previously. In this study, we revisit online knowledge distillation and find that the existing training strategy limits the diversity among peer networks. Thus, online knowledge distillation cannot achieve its full potential. To address this, a novel online knowledge distillation with elastic peer (KDEP) strategy is introduced here. The entire training process is divided into two phases by KDEP. In each phase, a specific training strategy is applied to adjust the diversity to an appropriate degree. Extensive experiments have been conducted on individual benchmarks, including CIFAR-100, CINIC-10, Tiny ImageNet, and Caltech-UCSD Birds. The results demonstrate the superiority of KDEP. For example, when the peer networks are ShuffleNetV2-1.0 and ShuffleNetV2-0.5, the target peer network ShuffleNetV2-0.5 achieves 57.00% top-1 accuracy on Tiny ImageNet via KDEP.

Motivation in organisational online knowledge sharing

PurposeThis paper aims to examine the influence of intrinsic motives (self-efficacy, reputation and reciprocity) on online knowledge sharing behaviour. Additionally, this research investigates the moderating role of individual innovation capability and top management support.Design/methodology/approachThe methodology adopted was a questionnaire survey of employees working in Vietnamese telecommunications companies. A total of 501 employees completed a self-administered anonymous survey using a cross-sectional design. Confirmatory factor analysis and ordinary least squared – based hierarchical regression was used to test the conceptual framework.FindingsSelf-efficacy, reputation and reciprocity significantly impact online knowledge sharing behaviour. Specifically, self-efficacy has an inverted U-shape association while reputation and reciprocity have a positively, returns-to-scale association with online knowledge sharing behaviour. Individual innovation capability moderates the effect on these associations as does top management support, but to a lesser extent.Research limitations/implicationsData were obtained at a single point in time and self-reported. Furthermore, this study was conducted in a specific industry in Vietnam, i.e. telecommunications, which limits the generalisability of the research.Practical implicationsOrganisations need to create a favourable environment for online knowledge sharing to foster reciprocal relationships and interpersonal interactions of employees. Encouraging and rewarding employees to actively engage in knowledge exchange will help facilitate reciprocal online knowledge sharing behaviour.Originality/valueThis study contributes to knowledge-sharing behaviour by uncovering an inverted U-shape association and positively, returns-to-scale associations between intrinsic antecedents and online knowledge sharing behaviour. Additionally, individual innovation capability was an important moderator which has been overlooked in past research.

Local Traffic-aware Green Algorithm based on Sleep-scheduling in autonomous networks

Over recent years, green communication has been investigated to reduce the economic costs and environmental pollution caused by network infrastructures. There exist many approaches to conserve energy in autonomous networks while according to over-provisioning of networking resources for peak traffic periods, sleep-scheduling based approach is one of effective methods between them. In this regards, in this paper, a new Local Traffic-aware Green Algorithm based on Sleep-scheduling (LTGAS) is proposed in autonomous wired networks in order to reduce energy consumption during low traffic periods. This proposal is a dynamic solution that considers online and local traffic knowledge to switch off some underutilized network nodes and links during low traffic periods and re-switch on some sleep devices in congestion situations. In addition, LTGAS is executed in fully distributed mode without any centralized controller and uses only information provided by link-state protocols like OSPF. Moreover, this solution does not have to gather global traffic knowledge of network during a sleep-scheduling decision, resulting in low complexity and low network overhead. The results obtained by the real network scenario show that LTGAS switches off up to 38% of network nodes and up to 96% of the maximum number of switchable links during low traffic periods. In addition, LTGAS has a low effect on network performance metrics, including end-to-end delay, packet delivery ratio and average link utilization, compared with similar proposals while switches off more number of network devices rather than other approaches.

Crowdsourcing for Innovative Knowledge: effects of Knowledge Synthesis and Centralised Communication Position

ABSTRACT As innovation is increasingly generated via crowdsourcing, factors that enable or impede collective innovation deserve a closer examination. This study advances the literature by examining the roles of knowledge synthesis and communication positions in open innovation challenges. Analysing 3,200 posts generated from 21 organisation-sponsored online crowd-based open innovation challenges. This study showed that when knowledge contributors occupy centralised positions in online knowledge collaboration, they are less likely to generate innovative knowledge, and the benefit obtained from synthesised knowledge tends to be hampered by the contributor’s centralised position in the interaction. This study adds a new dimension to explaining crowdsourcing for innovation by incorporating a perspective of communication position into crowdsourcing and open innovation research. It also sheds light on the practice of crowdsourcing by highlighting the design of platforms that can promote the synthesis of crowd members’ shared knowledge while encouraging diverse voices from non-centralised members of the crowd.

Knowledge Elicitation with Aboriginal Australian communities

This paper provides techniques for engagement and data collection in researching with Aboriginal Australian cultures, acknowledging significant differences in forms of communication and usage of Information Systems to the mainstream Australian culture. An approach to trust in relationships is developed by interpreting cultural aspects arising from the diverse relationships to technology developed by Aboriginal users. This work uses the existing Honeycomb model for social media development as a base framework for collaborative web systems and online knowledge sharing in the Indigenous domain. We present a series of product development research projects based in universities in NSW Australia, in particular user experience studies, to explain the relationship between the researchers and users and the products that are created in terms of the model. Some concepts and processes fundamental to engagement with Aboriginal Australian communities in the supply of appropriate information sharing technology are discussed in this context. For if Aboriginal people are to engage in IS development, we are sharing the knowledge or the culture that is embedded in the technology which can have detrimental effects. Either we are asking them to enter the culture that created the technology, that is assimilate, or we use engagement in design to change that technology to suit the culture.
