Objectives: Computerised neuropsychological assessments (CNAs) are proposed as an alternative method of assessing cognition to traditional pencil-and-paper assessment (PnPA), which are considered the "gold standard" for diagnosing dementia. However, limited research has been conducted with culturally and linguistically diverse (CALD) individuals. This study investigated the suitability of PnPAs and CNAs for measuring cognitive performance in a heterogenous sample of older, Australian CALD English-speakers compared to a native English-speaking background (ESB) sample. Methods: Participants were 1037 community-dwelling individuals aged 70–90 years without a dementia diagnosis from the Sydney Memory and Ageing Study (873 ESB, 164 CALD). Differences in the level and pattern of cognitive performance in the CALD group were compared to the ESB group on a newly developed CNA and a comprehensive PnPA in English, controlling for covariates. Multiple hierarchical regression was used to identify the extent to which linguistic and acculturation variables explained performance variance. Results: CALD participants' performance was consistently poorer than ESB participants on both PnPA and CNA, and more so on PnPA than CNA, controlling for socio-demographic and health factors. Linguistic and acculturation variables together explained approximately 20% and 25% of CALD performance on PnPA and CNA respectively, above demographics and self-reported computer use. Conclusions: Performances of CALD and ESB groups differed more on PnPAs than CNAs, but caution is needed in concluding that CNAs are more culturally-appropriate for assessing cognitive decline in older CALD individuals. Our findings extend current literature by confirming the influence of linguistic and acculturation variables on cognitive assessment outcomes for older CALD Australians. [ABSTRACT FROM AUTHOR]

The increasing number of self-report surveys being collected using computers has led to a body of literature examining the response rates for computerized surveys compared with the more traditional paper-and-pencil method. However, results from individual studies have been inconsistent, and the meta-analyses available on this topic have included studies from a restricted range of years and did not use proper statistical procedures for examining comparability. Consequently, we conducted a meta-analysis with 96 independent effect sizes spanning over two decades of studies; we also assessed potential moderators. Comparability was determined using confidence interval equivalence testing procedures. The meta-analysis indicated nonequivalence, with those in the paper-and-pencil condition being almost twice as likely to return surveys as those in the computer condition. There was large heterogeneity of variance, and 11 of the 18 potential moderators were significant. Two meta-regressions yielded only two significant unique moderators: population and type of measure. Results highlighted issues within the response rate literature that can be addressed in future studies, as well as provided an example of using equivalence testing in meta-analyses.

The large body of literature on the comparability of mean scores for self-report survey responses gathered using paper-and-pencil and computer data collection methodologies has yielded inconclusive results. However, no comprehensive meta-analysis has been conducted in this field, and those that are available for specific measures have typically not differentiated between studies using between-groups and within-subjects designs. Also, few individual studies, and no meta-analyses, have used correct statistical procedures to determine the equivalence of the two methodologies. Consequently, we conducted two meta-analyses assessing quantitative equivalence (i.e., mean scores), with the first consisting of 144 independent effect sizes from studies with between-groups designs and the second including 70 independent effect sizes from studies using within-subjects designs. Both meta-analyses assessing mean scores indicated equivalence across conditions, with large heterogeneity of variance in the between-groups analysis. Presence of others in both the paper-and-pencil and computer conditions accounted for a significant portion of this variance. Heterogeneity of variance was small for the within-subjects design analysis. Overall, results indicated that the mean scores for self-report surveys using paper-and-pencil and the computer are comparable, although heterogeneity differs for the study designs. Equivalence testing was demonstrated to be the recommended statistical procedure for this type of research. [ABSTRACT FROM AUTHOR]

Roger Kowalski's poem ‘L'autre face’, published in 1960, was set to music by Jean-Claude Risset some two decades later in a piece with the same title for soprano and computer-generated tape. The poem is a powerfully self-reflexive piece, foregrounding its status as a work on paper, in which the voice of the poet becomes audible only through an imaginative act of interpretation. This relationship between paper, voice, and interpretation is fundamental to the aesthetic tradition which the poem belongs. Risset's soprano part, like classical music generally, is similarly a work on paper, awaiting a voice; but his computer-generated tape is not. Does this mean we cannot interpret it in the same way? This essay argues that Kowalski's work and Risset's, despite the latter's new medium, both belong to a high art tradition in which ghostly voices emerge from beyond the physical substance of the work—whatever that substance may be.

The present study focused on how self-control over pace might help learners successfully extract information from digital learning aids. Past research has indicated that too much control over pace can be overwhelming, but too little control over pace can be ineffective. Within the popular self-testing domain of flashcards, we sought to elucidate the optimal level of user control for digital learning and compare learning outcomes between paper and digital flashcards. College students learned vocabulary from paper flashcards or one of several digital flashcard versions and were scored on their memory recall and asked about their perceptions of the learning process. With digital flashcards, students were randomly assigned to an automatic slideshow of cards with no user control, automatic slideshow with pre-set pauses, automatic slideshow where users could press the spacebar to pause at any time, or a self-paced slideshow with complete user control. Users reported feeling more in control when indeed having some control, but ultimately memory recall, cognitive load, and satisfaction were similar across the five versions. However, memory recall was positively related to user satisfaction with their specific flashcard set, and negatively related to users' perceived mental effort and difficulty. Notably, whether paper or digital, students showed individual variability in how they advanced through the words. This research adds to the educational literature by suggesting that paper and digital flashcards are equally viable options for students. Given differences between individual users and the connection between satisfaction and recall, individualistic options that offer, but do not force, some control over pace seem ideal. Paper flashcards may already include such options, and e-flashcards should offer similar adaptive features to appeal to a wide variety of users. [ABSTRACT FROM AUTHOR]

We compared the effects of two media (paper vs. computer) on reading comprehension and memorization among students in their third or fourth year of secondary school. To assess comprehension, we constructed and validated a text with a carefully controlled hierarchical structure, accompanied by a questionnaire containing three types of questions (surface, semantic, inference). Memory of the text was assessed with a test based on the Remember-Know (R/K) paradigm. The results of the comprehension and R/K tests indicated that there was no difference between the two media. Regardless of medium, surface comprehension was better than either semantic or inference comprehension. The R/K test indicated that memorization was better for the surface elements of the text (more R than K responses). In conclusion, overall results show that if we fulfil all the conditions of paper-based versus computerized presentation (text structure, presentation on a single page, screen size, several types of questions measuring comprehension and memory performances), reading performances are not significantly different.

Research is lacking on the equivalence of paper-and-pencil and computer-administered surveys in older adult samples. In addition, few comparability studies have used best practices for examining equivalence. The current study investigated quantitative (means), qualitative (internal consistency and intercorrelations), and auxiliary (missing items, completion time, and comfort) equivalence for completing self-report surveys in paper-and-pencil or computerized conditions in an older adult sample. One hundred and eight older adults ages 60 and over were randomly assigned to a paper-and-pencil or computer condition and completed questionnaires assessing personality, social desirability, and computer self-efficacy. Results generally showed qualitative equivalence, with some notable differences for quantitative and auxiliary equivalence. [ABSTRACT FROM AUTHOR]

The aim of this paper was to assess the validity and reliability of the touch-screen standard Portuguese version of the following patient-reported outcomes (PROs), compared with paper format, in patients with rheumatoid arthritis (RA) and spondyloarthritis: Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Ankylosing Spondylitis Quality of Life scale (ASQoL), Short-Form 36 (SF-36), Health Assessment Questionnaire (HAQ) and visual analogue scales (VAS) measuring pain and burden of disease. Adult patients with RA and spondyloarthritis attending the Portuguese Institute of Rheumatology were recruited from March 2013 to January 2014. Patients filled the paper and touch-screen formats of the standard Portuguese versions of the PROs. Two groups of VAS were used, RA and psoriatic arthritis (Global VAS) and another specific for spondyloarthrites (Spa-VAS). Paper questionnaires were filled 15 min before touch-screen formats. Agreement between formats (validity) was assessed by intraclass correlation coefficient (ICC), while internal consistency of scales (reliability) was assessed by Cronbach's alpha. Overall, 134 patients were included with a mean age of 51 years, 74.6 % female and 57.5 % presenting RA. BASDAI, BASFI, HAQ and ASQoL showed high ICC between paper and touch-screen formats (0.977, 0.958, 0.974 and 0.940, respectively). ICC for Global VAS ranged from 0.906 to 0.921, while Spa-VAS ranged from 0.867 to 0.943. The mean ICC for all SF-36 domains was 0.889 (ICC for each domain ranged from 0.781 to 0.944). Touch-screen standard Portuguese formats of these PROs may be valid and reliable tools for PRO measurement in rheumatology. [ABSTRACT FROM AUTHOR]

The article presents a study that aim to assess the measure's equivalence across paper-and computer-based survey formats in a community-based school setting. The use of computers and electronic systems to complete questionnaires is becoming popular in health and education research. The electronic methods have good efficiency in collecting, managing and storing data.

Adherence and accuracy of self-monitoring of dietary intake influences success in weight management interventions. Information technologies such as computers and smartphones have the potential to improve adherence and accuracy by reducing the burden associated with monitoring dietary intake using traditional paper-based food records. We evaluated the acceptability and accuracy of three different 7-day food record methods (online accessed via computer, online accessed via smartphone, and paper-based). Young women (N=18; aged 23.4±2.9 years; body mass index 24.0±2.2) completed the three 7-day food records in random order with 7-day washout periods between each method. Total energy expenditure (TEE) was derived from resting energy expenditure (REE) measured by indirect calorimetry and physical activity level (PAL) derived from accelerometers (TEE=REE×PAL). Accuracy of the three methods was assessed by calculating absolute (energy intake [EI]–TEE) and percentage difference (EI/TEE×100) between self-reported EI and TEE. Acceptability was assessed via questionnaire. Mean±standard deviation TEE was 2,185±302 kcal/day and EI was 1,729±249 kcal/day, 1,675±287kcal/day, and 1,682±352 kcal/day for computer, smartphone, and paper records, respectively. There were no significant differences between absolute and percentage differences between EI and TEE for the three methods: computer, –510±389 kcal/day (78%); smartphone, –456±372 kcal/day (80%); and paper, –503±513 kcal/day (79%). Half of participants (n=9) preferred computer recording, 44.4% preferred smartphone, and 5.6% preferred paper-based records. Most participants (89%) least preferred the paper-based record. Because online food records completed on either computer or smartphone were as accurate as paper-based records but more acceptable to young women, they should be considered when self-monitoring of intake is recommended to young women.

Since the advent of modern electronics technology, heat transfer science and engineering has served in the development of computer technology. The computer as an object of heat transfer research has a unique aspect; it undergoes morphological transitions and diversifications in step with the progress of microelectronics technology. Evolution of computer's hardware manifests itself in increasing packing density of electronic circuits, modularization of circuit assemblies, and increasing hierarchical levels of system internal structures. These features are produced by the confluence of various factors; the primary factors are the pursuit of ever higher processing performance, less spatial occupancy, and higher energy utilization efficiency. The cost constraint on manufacturing also plays a crucial role in the evolution of computer's hardware. Besides, the drive to make computers ubiquitous parts of our society generates diverse computational devices. Concomitant developments in heat generation density and heat transfer paths pose fresh challenges to thermal management. In an introductoiy part of the paper, I recollect out-experiences in the mainframe computers of the 1980s, where the system's morphological transition allowed the adoption of water cooling. Then, generic interpretations of the hardware evolution are attempted, which include recapturing the past experience. Projection of the evolutionary trend points to shrinking space for coolant flow, the process commonly in progress in all classes of computers today. The demand for compact packaging will rise to an extreme level in supercomputers, and present the need to refocus our research on microchannel cooling. Increasing complexity of coolant flow paths in small equipment poses a challenge to a user of computational fluid dynamics (CFD) simulation code. In highly integrated circuits the paths of electric current and heat become coupled, and coupled paths make the electrical/thermal codesign an extremely challenging task. These issues are illustrated using the examples of a consumer product, a printed circuit board (PCB), and a many-core processor chip. [ABSTRACT FROM AUTHOR]

Objectives: Patient-reported outcomes (PROs; self-report assessments) are increasingly important in evaluating medical care and treatment efficacy. Electronic administration of PROs via computer is becoming widespread. This article reviews the literature addressing whether computer-administered tests are equivalent to their paper-and-pencil forms. Methods: Meta-analysis was used to synthesize 65 studies that directly assessed the equivalence of computer versus paper versions of PROs used in clinical trials. A total of 46 unique studies, evaluating 278 scales, provided sufficient detail to allow quantitative analysis. Results: Among 233 direct comparisons, the average mean difference between modes averaged 0.2% of the scale range (e.g., 0.02 points on a 10-point scale), and 93% were within ±5% of the scale range. Among 207 correlation coefficients between paper and computer instruments (typically intraclass correlation coefficients), the average weighted correlation was 0.90; 94% of correlations were at least 0.75. Because the cross-mode correlation (paper vs. computer) is also a test–retest correlation, with potential variation because of retest, we compared it to the within-mode (paper vs. paper) test–retest correlation. In four comparisons that evaluated both, the average cross-mode paper-to-computer correlation was almost identical to the within-mode correlation for readministration of a paper measure (0.88 vs. 0.91). Conclusions: Extensive evidence indicates that paper- and computer-administered PROs are equivalent. [ABSTRACT FROM AUTHOR]

Abstract: This study reports results from a format comparison between Web-based and pencil and paper questionnaires measuring two well-validated measures of psychological distress among 530 frequent Internet users studying at an on-line University (Open University of Catalonia, UOC). A four-item version of the Perceived Stress Scale (PSS) and a seven-item version of the Center for Epidemiological Studies-Depression Scale (CESD) were randomly administered in Web-based and pencil and paper format. Internal consistency analyses showed that these two brief versions were reliable for on-line assessment. Also, no differences in Cronbach αs were found between formats. Exploratory as well as multigroup factor analysis techniques showed that factor structures were invariant across formats. Overall, results revealed that respondents did not bias their responses in the Web-based condition. As these findings suggest, when familiarity with technology is high among respondents and sample procedures are followed to maximize control for potential participants, Web-based and paper and pencil formats are virtually equivalent, as in the two brief measures of psychological distress used in this study.

This paper reports on the results of a study of English children's performance on a computer mathematics assessment compared with a pencil-and-paper assessment. Two matched samples of children were each assessed on one of two mathematics pencil-and-paper tests and assessed a month later on a cloned computer test. The performance scores were better on the computer tests than on the pencil-and-paper tests, although this was not statistically significant in every case. The paper goes on to discuss some of the differences between performance and approach to the question between the two media, and explores possible reasons for these differences. In conclusion, the computer tests were found to have an overall positive effect on children's performance, although not for every child and, in some instances, the computer assessment limited the way in which a question could be answered.

To compare responses to personally sensitive questions, 352 undergraduates were randomly assigned to respond anonymously to a survey using one of three survey methods: pencil and paper mail-in, Internet survey, or an automated touch-tone telephone response system. The survey contained 68 brief Yes/No questions ranging from low to high sensitivity in 13 domains, such as general honesty, academic honesty, prejudice, illegal behavior, alcohol use, substance use, violence, and sexual behavior. We found no significant differences (p>0.05) in participants’ responses among these three media for any of the questions. This suggests that for some populations, under some circumstances, Internet and touch-tone telephone systems achieve the same results as traditional pencil and paper surveys.

Abstract: The purpose of this study was to examine the reliability, equivalence and respondent preference of a computerized version of the General Health Questionnaire (GHQ-12), Symptom Checklist (SCL-90-R), Medical Outcomes Study Social Support Survey (MOSSSS), Perceived Stress Scale (PSS) and Utrecht Coping List (UCL) in comparison with the original version in a general adult population. Internal consistency, equivalence and preference between both administration modes was assessed in a group of participants (n =130) who first completed the computerized questionnaire, followed by the traditional questionnaire and a post-assessment evaluation measure. Test–retest reliability was measured in a second group of participants (n =115), who completed the computerized questionnaire twice. In both groups, the interval between first and second administration was set at one week. Reliability of the PC versions was acceptable to excellent; internal consistency ranged from α =0.52–0.98, ICC’s for test–retest reliability ranged from 0.58–0.92. Equivalence was fair to excellent with ICC’s ranging from 0.54–0.91. Interestingly, more subjects preferred the computerized instead of the traditional questionnaires (computerized: 39.2%, traditional: 21.6%, no preference: 39.2%). These results support the use of computerized assessment for these five instruments in a general population of adults. [Copyright &y& Elsevier]

Big data technology has undoubtedly accelerated the efficiency of data processing, made data become an important reference basis in enterprise operation, and changed the mode of enterprise operation as well as the existing business model. With the development of computer technology and related equipment, more and more enterprises and organizations can begin to use big data processing technology. However, many small and medium-sized enterprises, because they cannot afford the high cost of research and development and leasing, are gradually eliminated in the information-based business competition, so it is necessary to adopt certain strategies to help small and medium-sized enterprises out of this crisis. For fragmented big data obtained from different data sources, this paper adopts load-balancing technology to provide horizontal service cluster scalability and designs a separate system module for routine testing. The experimental results show that the improved big data processing system based on genetic algorithm in this paper can better meet the business needs of small and medium-sized enterprises and meet the application needs of small and medium-sized enterprises. The simulation results also show the advantages of the system in this paper, which is faster, higher accuracy, less energy consumption, lower requirements for equipment, and more suitable for small and medium-sized enterprises. This paper designs a kind of effective big data processing system by studying genetic algorithm and computer technology. [ABSTRACT FROM AUTHOR]

The demand for higher and tertiary education in Africa is now high, and as a result, public institutions are enrolling many students, a phenomenon now called massification (Pillay, 2020; Noui, 2020). The term massification is defined as the increase in the enrollment of students without a proportionate boost in resources (Adetiba, 2019; Mohamedbhai, 2016). Zimbabwean universities are enrolling many students to fund operations since government funding has dwindled (Garwe, 2016; Madzimure, 2016). The provision of quality education is becoming a challenge due to the high lecturer-student ratio, especially on courses that are highly practical in nature (Adetiba, 2019). There is a lack of proper management and engagement of students in very large classes, and as a result, students resort to memorizing content learned instead of engaging in critical thinking (Madzimure, 2016; Lee, 2016). Literature points out that if students develop self-regulated learning strategies, they will overcome challenges brought by massification. The purpose of this paper was to develop and evaluate the impact of a multimedia teaching tool in assisting students to develop selfregulated learning strategies so that they improve their performance while learning computer programming in a large class setup. Purposive sampling was used in this study, and the researcher adhered to design science research methodology.Students enrolled in introduction to computer programming used the multimediaClearn teaching tool that was developed hencepurposive sampling was used in this study.One class (BITH131) was the control group and students enrolled in BSIT 131 were the experimental group. Results obtained indicated that students who used the Clearn teaching tool performed better in a programming test as compared to students in the control group. [ABSTRACT FROM AUTHOR]

The basis of this paper is the Decision on the adoption of the Informatics curriculum for primary schools and gymnasia in the Republic of Croatia and, in particular, its stipulation that health is one of the fundamental values in the educational process. In a broad sense, healthcare and health education involves the understanding of the role of environmental factors, the understanding of health as a prerequisite, a foundation, and an indicator of sustainable development of society as a whole, as well as the understanding and adopting healthy habits, while avoiding the harmful ones. The purpose and the goal is to motivate the adoption of healthy lifestyle and responsible behavior and to provide the necessary knowledge and support. The emphasis is put on the importance of proper lifelong healthcare, on the preservation and improvement of health, on prevention of disease and their consequences, disability, and premature death. It is particularly important to include the content on occupational health and safety into the school course curricula. According to the aforementioned Decision taken in 2018, the pupils in primary schools in grades 1 to 4 will have the possibility to choose Informatics as an optional course from the school year 2020/21 onwards. The first part of the paper presents an excerpt from the Decision, as well as the excerpt from the Informatics curriculum for primary schools and gymnasia as the subject of the said Decision. Both excerpts cover the aspect of preservation and protection of health during work on a computer through adoption of basic terminology, rights and obligations, and the rules of kinesiology that refer to movement, sitting and posture. The second part of the paper presents the analysis of the content of textbooks used for the course informatics in grades 1 to 4 in elementary schools, in particular the parts that help the pupils understand and apply the safety recommendations that were given to preserve and protect health during work on a computer.

Humans have the ability to quickly identify their own environment, understand, judge and analyze it, which is one of the important reasons why human beings can survive in nature for a long time and gradually develop it into a prosperous society today. The key to human's ability to perceive and understand the environment lies in the ability to accurately find and identify objects, understand and describe visual scenes, and even express emotions on this basis. And if computers can realize automatic and accurate image recognition, and even understand the semantics of images correctly, it will surely improve and facilitate human life. Based on this, the author integrated and optimized the computer image recognition system and applied it in this paper. The core technology of the system is to improve the image algorithm, which can complete the training, testing and classification of target images. The experimental data are available. Choosing this algorithm to improve the learning and training of the data generated by the original image processing is more effective than directly training the original image.

Digital image technology is penetrating into various fields of people's life, and it has been very mature and can effectively store and transmit data. Moreover, there are still various researches on image recognition, the core of this technology. The algorithm is mainly based on computer technology to obtain the target image for different scene categories, thus completely replacing the traditional classification form. Because of the limitations of traditional identification technology, there are some problems in the actual use. It does not depend on the prior knowledge requirements and can carry out complex feature space division. In this paper, an image recognition computer system is established by introducing an improved neural network algorithm. The algorithm is designed and tested, and the results show it has lower image recognition error rate. Subsequently, this research result is applied to the actual scene for testing. The test results show that the improved neural network optimization algorithm can make the extracted features more accurately expressed in the image processing, which is more effective than the traditional algorithm.

Hypertext refers to the electronic links of texts. In the traditional texts, readers have to follow the linearity, and fixity of the book they are reading. Now computers give them a chance to escape this sort of restriction. Computer is a medium for the creation and the reading of texts. Hypertext or digital text, as we know, takes the form of a series of links. These links are adaptable, flexible, and interactive. They question the unity of the text, and the roles of both the reader and the author. Hence, hypertext requires redefining the concepts of author, reader, text, and structure--concepts of great importance to postmodernists. In addition, hypertext consists of fragments, pastiches, different styles and genres. It ignores boundaries, and addresses the mass. In brief, hypertext develops and brings to live many postmodern concepts such as decentering, intertextuality, writerly text and rejection of linearity and fixity of linear narrative. My paper is about hypertext in the light of postmodern theory. [ABSTRACT FROM AUTHOR]

In surveys, individuals tend to misreport behaviors that are in contrast to prevalent social norms or regulations. Several design features of the survey procedure have been suggested to counteract this problem; particularly, computerized surveys are supposed to elicit more truthful responding. This assumption was tested in a meta-analysis of survey experiments reporting 460 effect sizes (total N =125,672). Self-reported prevalence rates of several sensitive behaviors for which motivated misreporting has been frequently observed were compared across self-administered paper-and-pencil versus computerized surveys. The results revealed that computerized surveys led to significantly more reporting of socially undesirable behaviors than comparable surveys administered on paper. This effect was strongest for highly sensitive behaviors and surveys administered individually to respondents. Moderator analyses did not identify interviewer effects or benefits of audio-enhanced computer surveys. The meta-analysis highlighted the advantages of computerized survey modes for the assessment of sensitive topics. [ABSTRACT FROM AUTHOR]

This study introduces a computer modeling approach for mining vehicle fleet monitoring. Computer modeling helps to reduce prototyping costs and lower the risks of initial launch failure by analyzing and configuring the prototype in order to test various options and find the most fitting ones. We show in the first part of the study that using a computer modeling method, it is possible to test numerous combinations of metrics acquired during vehicle monitoring in the simulation rather than adding equipment to vehicles during prototyping Usage of real hardware during the prototype phase adds downtime to the vehicle fleet and reduces productivity. Along with those drawbacks, it also introduces the possibility of additional costs if the configuration needs to be changed later. By leveraging modern time-series data storage solutions, we present an easier approach to analyze real-world data retrieved using a simulation as a proxy. In the second part of the paper, we then propose a workflow of integrating SUMO with a time-series storage database through an Application Programming Interface (API) called TraCI, allowing for aggregation of vehicle fleet data over time and visualizing that data on the dashboard. At the end of the paper, we show a measuring methodology and provide a viable solution for the efficient transfer of telemetry data. [ABSTRACT FROM AUTHOR]

The use of advance computer-based technology is becoming necessary to address the growing complexity of human problems and enhance effective communication. The recent pandemic COVID-19 not only induces many morbidities and mortalities but also intensifies mental health problem worldwide. Due to the increasing benefits of virtual reality (VR) in addressing medical condition, it is believed that VR can be used as a diagnostic tool to assess numerous medical conditions and psychiatric disorders. To date, there is still scarce evidence of VR as a diagnostic tool to assess obsessive compulsive disorder (OCD). In this study, we had conducted a systematic review to investigate the use of VR as a diagnostic tool for OCD and assess its benefits and weaknesses in comparison to computer-assisted tools. Comprehensive searches of electronic databases including PubMed and Google Scholar were undertaken to discover peer review evidence of computer-based simulation tasks in detecting OCD symptoms. Twelve out of 9325 papers were screened and reviewed. Five articles reported on computerised tools and seven articles described VR tools. In comparison to computer-based tasks, VR is a promising assessment tool due to specific virtual environments and high resolutions which are able to induce anxiety symptoms. Despite numerous shortcomings, assessment can be utilised in computerised form to detect and generate a variety of psychiatry diagnoses among the general population. Although computerised assessment task and VR show promising results, the finding are uneven due to study design differences, wide variability content task use, small sample size, several methodological issue with the computerised tasks and lack of appropriate control groups. In conclusion, the choice to use computerisation or VR for OCD assessment will depend on aim, content, technical equipment and budget. More in-depth studies of these issues are required.

Learning performance evaluation is an important part of computer English teaching. Through evaluation, students can understand whether they have reached the learning goals of a lesson, and what are their shortcomings, so that they can continuously improve and improve themselves against these shortcomings. Combining actual needs, based on neural network and artificial intelligence technology, this paper constructs a computer English learning performance evaluation model based on machine learning. The computer English learning performance evaluation system in this paper is constructed on the basis of auditory characteristics and introduces a wavelet entropy feature based on the best tree wavelet packet decomposition, and it is applied to the establishment of an adaptive model. Moreover, this paper uses controlled experiments to analyze the model performance and combines mathematical statistics to visually display the model effect. From the research results, it can be seen that the performance of the model constructed in this paper basically meets the expected requirements and actual needs. [ABSTRACT FROM AUTHOR]

This paper provides a qualitative meta-analysis of the literature on the use of serious games to assist learners with intellectual and developmental disabilities. It aims to identify the research trends and the possible directions for future research. The study begins with a preliminary online search and selection of a sample of articles to identify the main categories of disabilities. This is followed by a detailed analysis of a selection of articles chosen on the basis of their relevance, year of publication and representation of the studies carried out in this field. The preliminary analysis of articles published in recent years showed that the majority of the articles dealt with the use of digital games to support learners with intellectual disabilities. The findings revealed reports of participants' higher engagement levels and motivation when learning with serious games, in addition to improved competence or performance in domains of language learning and numeracy. Nevertheless, most researchers acknowledged the need for more rigour in validating the effectiveness of the new games as learning tools. [ABSTRACT FROM AUTHOR]

The study is a systematic review and meta-analysis of prospective randomised control studies and prospective cohort studies of mid-term functional outcome of total knee replacement undertaken using imageless computer navigation compared with conventional instrumented total knee replacement. The literature search strategy included a search of the electronic databases, visual scanning of reference lists, hand searching of key journals and conference proceedings, and abstracts, citations, and trial registers. In total, 440 papers were retrieved after removal of duplicates, and with further screening, 11 papers were included in the systematic review and 6 papers were considered appropriate for meta-analysis. Analysis of the data showed evidence of a modest improvement in functional outcome at mid-term follow-up with use of imageless computer navigation assistance compared with conventional instrumented total knee replacement with a total score point estimate of 3.36 confidence interval (CI) (− 0.583, 7.298), objective score point estimate of 1.45 CI (0.11, 2.799), and functional score point estimate of 2.4, CI (− 1.174, 5.977). The predominant risk of bias was from random allocation and attrition. There is evidence of a modest improvement in functional outcome with the use of imageless computer navigation assistance compared with conventional instrumented total knee replacement at mid-term follow-up.

Background: The aim of this study was to determine the repeatability of an automated-ETDRS (Early Treatment Diabetic Retinopathy Study) near and intermediate visual acuity measurement in subjects with normal visual acuity and subjects with reduced visual acuity. The agreement of automated-ETDRS with gold standard chart-based visual acuity measurement was also studied.Methods: Fifty-one subjects were tested (aged 23 to 91 years; 33 subjects with normal visual acuity: 6/7.5 or better; 18 subjects with reduced visual acuity: 6/9 to 6/30). Near and intermediate visual acuity of one eye from each subject was measured with an automated tablet-computer system (M&S Technologies, Inc.) and Precision Vision paper chart in a random sequence. Subjects were retested one week later. Repeatability was evaluated using the 95 per cent limits of agreement (LoA) between the two visits.Results: Average difference between automated-ETDRS near visual acuity and near visual acuity by paper chart was 0.02 ± 0.10 logMAR (p > 0.05). Agreement of near visual acuity between automated-ETDRS and paper chart was good, with 95 per cent LoA of ±0.19 logMAR. Furthermore, automated-ETDRS near visual acuity showed good repeatability (95 per cent LoA of ±0.20). Mean difference between automated-ETDRS intermediate visual acuity and intermediate visual acuity by paper chart was 0.02 ± 0.10 logMAR (p > 0.05). Agreement of intermediate visual acuity between automated-ETDRS and paper chart was good, with 95 per cent LoA of ±0.20 logMAR. In addition, automated-ETDRS intermediate visual acuity had good repeatability (95 per cent LoA of ±0.16).Conclusion: Automated-ETDRS near and intermediate visual acuity measurement showed good repeatability and agreement with the gold standard chart-based visual acuity measurement. The findings of this study indicate the automated visual acuity measurement system may have potential for use in both patient care and clinical trials. [ABSTRACT FROM AUTHOR]

The application of artificial intelligence and machine learning algorithms in education reform is an inevitable trend of teaching development. In order to improve the teaching intelligence, this paper builds an auxiliary teaching system based on computer artificial intelligence and neural network based on the traditional teaching model. Moreover, in this paper, the optimization strategy is adopted in the TLBO algorithm to reduce the running time of the algorithm, and the extracurricular learning mechanism is introduced to increase the adjustable parameters, which is conducive to the algorithm jumping out of the local optimum. In addition, in this paper, the crowding factor in the fish school algorithm is used to define the degree or restraint of teachers’ control over students. At the same time, students in the crowded range gather near the teacher, and some students who are difficult to restrain perform the following behavior to follow the top students. Finally, this study builds a model based on actual needs, and designs a control experiment to verify the system performance. The results show that the system constructed in this paper has good performance and can provide a theoretical reference for related research. [ABSTRACT FROM AUTHOR]

Summary: The performance of backhaul networks is the major concern for internet service providers, cloud service providers, and data centers for redundancy and reliability. With the integration of new data communication technologies, the system should be more smart and intelligent to handle data traffic coming from new networks like 5G. This new 5G standard provides connectivity among devices where all the traffic is handled by backbone and backhaul networks. The devices and nodes need multiple interfaces, but the TCP/IP standard uses a single path per connection for data communication. This limitation leads to the degradation of network performance and communication failures. There is a need to enhance data throughput and performance by using available paths and interfaces. Multipath Transport Control Protocol (MTCP) is one of the advanced extension of the TCP/IP standard for using available interfaces. This paper proposed an MTCP based infrastructure for 5G networks to handle all the coming data from these networks and provide fast reliable data handling. The proposed infrastructure is evaluated in simulation to check its performance with existing standards. The results indicate that the proposed infrastructure is minimizing the convergence time in case of any failure in the main path. [ABSTRACT FROM AUTHOR]

This paper aims to analyze the perceptions that the students of the face-to-face Public Accounting program of the Universidad Militar Nueva Granada in Bogotá hold about their learning and their satisfaction with using virtual learning environments. To that end, a sample of 106 students who had taken financial accounting courses was used. The variables selected for the analysis were 77 observable variables, four endogenous latent variables (satisfaction, student-student relationship, and professor-student relationship in two dimensions), and one exogenous latent variable (perceived learning). The modeling was done using the Structural Equation Model (SEM). Per our findings, the professor-student interaction in its two dimensions positively affects both perceived learning and student satisfaction, which does not occur with the student-student relationship. The main conclusion is that professor's actions in virtual learning improve learning, but collaboration between students exerts no effect on their perceived learning. [ABSTRACT FROM AUTHOR]

Objective: Comorbid substance misuse and mental health difficulties are recognized as a leading contributor to disease burden worldwide. Amid cuts to health care services, computer-based interventions may provide support for patients experiencing these difficulties. The aims of this systematic review were to identify and investigate the efficacy of these computer-based interventions at improving substance misuse and mental health outcomes. Methods: A systematic search was conducted of CINAHL Plus, PsycARTICLES, PsycINFO, Medline, Web of Science, and the Cochrane Library. Gray literature was also searched for relevant papers. Data were extracted from 33 papers, which met eligibility criteria by reporting a computer-based intervention designed to treat substance misuse and mental health in adults. Quality assessments were conducted on these papers. Results: Computer-based interventions generally led to an improvement of substance misuse and mental health outcomes within groups and when compared against waitlist control and psychoeducation. Computer-based interventions were effective at improving dual diagnosis outcomes, and improvements to mental health outcomes specifically were maintained for up to nine months. However, the combined effect of computer-based interventions and therapist support was found to be more effective than the effects of computer-based interventions alone. Conclusions: Many papers were limited by high attrition rates commonly attributed to "digital" interventions. Future research should consider systematically recruiting a range of participants, including those potentially affected by the digital divide, and incorporating methods within research to maintain engagement. This review was also limited by the heterogeneity of the papers reported, many of which differed between targeting dual diagnosis and targeting either substance misuse or mental health respectively, with outcomes investigating other difficulties out of curiosity.

The beginnings of cybernetics were marked by the publication of two papers in 1943. In the first one, Rosenblueth, Wiener, and Bigelow claimed that purposeful behavior is a circular process controlled by negative feedback. In the second seminal paper, McCulloch and Pitts proposed that neurons are interconnected working as logical operators. Both articles raised human-machine analogies and mathematically formulated cognitive mechanisms. These ideas ignited the interest of von Neumann, who was developing the first stored-program computer. Thus, after a preliminary meeting in 1945, a series of meetings were held between 1946 and 1953. The role of the Spanish neurophysiologist Rafael Lorente de Nó in the beginnings of cybernetics is attested not only by his participation in the core members of these Macy conferences but also for his previous description of reverberating circuits formed by a closed chain of internuncial neurons. This was the first neurobiologic demonstration of a feedback loop. Most researchers considered the central nervous system as a mere reflex organ until then; nevertheless, he demonstrated a self-sustained central activity in the nervous system, supporting the idea of self-regulating mechanisms as a key concept not just in machines but also in the brain.

Virtual painting technology is a new technical means of modern art creation. 3D painting is a branch of virtual reality art. It uses computers or other intelligent computing devices to simulate the virtual 3D space environment, so that art creators can immerse themselves in painting creation. The difference between 3D painting and traditional painting is that it is a painting space from two-dimensional to three-dimensional. It is a painting creation process of double immersion of human brain and limbs. We believe that the artistic exploration of 3D painting is helpful to the improvement of painting artistic creation ideas and the expansion of skills. It is an embodiment of enriching the media and visualization of painting. Due to the complexity of 3D painting, this paper creates a cloud platform based on the high-speed and large storage characteristics of cloud computing, which will provide more efficient and convenient experience for 3D painting users. The key to the development of the cloud platform is to build an NX digital modeling and display platform based on cloud computing. Through the compression, serialization and network transmission of the three-dimensional image technology at the NX end, the three-dimensional model is finally displayed in the browser interface, and the basic functions of interacting with the model are provided for users. Cloud computing technology is used to arrange the computing work of 3D model compression into subsequent computing, which greatly reduces the redundancy of users' work. Through the research of cloud computing, this paper applies it to computer image technology, which makes the application of 3D painting flourish. [ABSTRACT FROM AUTHOR]

At present, China's urbanization transformation is accelerating, the construction industry is developing rapidly, and people's requirements for buildings are also increasing, which leads to the increasing energy consumption.

This paper designs a kind of intelligent building energy-saving management system by studying computer vision algorithm. [ABSTRACT FROM AUTHOR]

Abstract: Children now have considerable exposure to new information technologies (IT) such as desktop computers. A reported association between computer use and discomfort in children has prompted concerns about the musculoskeletal stresses associated with computer use. There were no detailed data on children reading and writing, nor any evidence on the variability of postures and muscle activity whilst children use IT. Twenty-four children (10–12 years old; 12 male) performed a reading and writing task using new IT (computer/keyboard/mouse with high display and mid height display) and old IT (book/paper/pen). Spinal and upper limb 3D posture and muscle activity were recorded and estimates of mean and variation calculated. The mean postures for children reading and writing with computers were more neutral than when they read and wrote with old IT. Similarly, mean muscle activity levels were lower during computer use than old IT use. However, new IT use also resulted in less variable, more monotonous postures and muscle activities. Moderate differences in computer display height had little effect on posture and muscle activity variation. Variation in musculoskeletal stresses is considered an important component of the risk of musculoskeletal disorders. Children should therefore be encouraged to ensure task variety when using new IT to offset the greater posture and muscle activity monotony. [Copyright &y& Elsevier]

Introduction. This review paper deals with literature analysis of modern computer vision and image analysis methods in cheese-quality evaluation. Materials and methods. In this paper several cheese types made from cow's milk were analyzed: soft, semihard, and hard cheese. All images shown in this paper were scanned with a flatbed scanner, and then processed using ImageJ software. Results and discussion. Because with the most part of the external quality attributes evaluation is timeconsuming, due to visual inspection, computer vision provides a means to perform this task automatically. To evaluate various cheese external quality properties (color), and defects (mechanical openings - gas holes; rind defect - formation of calcium lactate crystals and excessive rind halo; amount and distribution of added ingredients; meltability and oiling-off) computer vision system has been successfully applied. Image analysis was used for measurement of the normal amount of gas production, and abnormal shape or distribution of eyes throughout the structure of Emmental and Tilsit cheese. Image analysis was used to determine the presence of rind halo cheese defect and to measure the area occupied by calcium lactate crystals on surfaces of naturally smoked Cheddar cheese samples. To improve empirical methods (Arnott and the Schreiber test) and to offer a new approach for evaluation of meltability and oiling-off of Mozzarella cheese, computer vision and image analysis method was applied. In addition, digital image analysis is used for evaluation of the addition of some ingredients and evaluation of the amount and distribution of added ingredients into the semi-cooked cheese with added paprika and herbs. Conclusion. Computer vision and digital image analysis represents an efficient and non-invasive technique able to investigate the cheese optical properties and give information concerning their composition and structure.

This study examined whether computerized dynamic testing by utilizing a robot would lead to different patterns in children's (aged 6–9 years) potential for learning and strategy use when solving series‐completion tasks. The robot, in a "Wizard of Oz" setting, provided instructions and prompts during dynamic testing. It was found that a dynamic training resulted in greater accuracy and more correctly placed pieces at the post‐test than repeated testing only. Moreover, children who were dynamically trained appeared to use more heuristic strategies at the post‐test than their peers who were not trained. In general, observations showed that children were excited to work with the robot. All in all, the study revealed that computerized dynamic testing by means of a robot has much potential in tapping into children's potential for learning and strategy use. The implications of using a robot in educational assessment were stressed further in the discussion. Lay Description: What is already known about this topic: ○Computerized dynamic testing provides information on children's potential for learning.○Computerized testing can be of help in the fine‐tuning of assessment outcomes.What this paper adds: ○Dynamic testing with a peer/table robot provides information on children's potential for learning.○Dynamic testing and training by a peer robot results in greater accuracy in solving an inductive reasoning task than repeated testing only.○Dynamically trained children show a more advanced use of analytic task solving than their peers who were not trained by a peer robot.○Dynamic testing with a peer/table robot provides detailed, step‐by‐step information regarding children's need for instruction during assessment.○Children were very eager to work with the peer/table robot. Implications for practice and/or policy: ○Detailed assessment information derived from dynamic testing may be more suitable to inform education.○Computerized testing with a peer/table provides a motivating testing environment for children who can work independently, in their own tempo, on a task.○In future, a peer/table robot may be of help in teaching/assessment situations in education.
