A public health emergency of international concern, such as a pandemic, disrupts the normal operation of the global supply chain, which necessitates in-depth research on supply chain management. In this paper, we used bibliometric and content analysis to provide a systematic analysis of the supply chain industry from this background. The descriptive analysis provides insights into the publication growth trajectory, in terms of the contributing authors, countries, and subject categories, which presents an intuitive display of previous research. In addition, the existing research mainly covers three dimensions of supply chain disruption, strategies, and sustainability, which can be clustered into supply chain disruption, disruption recovery, reconfiguration, digital intelligence, optimization, and sustainability. By revisiting the supply chain industry, we explored the transformation of its characteristics in the pandemic, covering themes ranging from expansion to contraction, from traditional to digital intelligence, and from fragile to sustainability, which suggests potential research directions for future studies. This contributes to the further research of supply chain management during the pandemic and provides supply chain managers with a practical approach for dealing with supply chain disruption risks and improving supply chain sustainability in this context.

This research was aimed to find out the evaluation from the students of undergraduate, graduate, and doctor program toward library resources in the Faculty of Psychology, Universitas Gadjah Mada. The result of this research was expected to give benefit to develop the library resources for giving the excellent services to the user. This research used quantitative method, questionnaire as the data collection method, and descriptive statistic method for analizing data. The subject of this research was 159 students from undergraduate, graduate, and doctor program as the user of the library. The results showed standard value for each program: undergraduate (2,545963), graduate comprised with Master of Science (2,644517) and Master of Profession (2,541234), and doctor (2,982143). If the value higher than (>) standard value included high categories and less than (<) or equal with (:) standard value included low categories. The comprehensive result of this research showed that (1) high categories evaluation came from the aspects of collection relevancy, circulation, facilities (security, temperature, light, and lay out), and human resources; (2) low categories evaluation came from the aspects of collection (composition of subject and language), services (time, number of collection, duration of borrowing books, and interlibrary borrowing books), facilities (space, table, and chair), information technology (computer/internet, internet accessibility, and multimedia); and (3) variation of high-low evaluation came from the aspects of collection (recently and completeness) services (searching, multimedia, and fine), and information technology (library based on information technology and browsing).

With regards to previous research results on how the teacher’s/preschool teacher’s understanding of a subject effects children’s learning and apprehending of the subject combined with the difficulties for the technology subject to take place in preschool this study aims at investigating how preschool staff (including preschool teachers and day care attendants) describe technology. A qualitatively designed questionnaire was sent out to 139 preschool teachers and day care attendants in a Swedish municipality, whereof 102 answered. The open question about what technology is thought to be was analyzed using a conventional content analysis resulting in nine categories, of which six interrelated hierarchically and one contained answers witch could not be categorized. Thus the result shows eight different ways in which technology is described, from a simple and naive description to a more complex description that implicates a deeper understanding of technology. A majority describes technology according to the latter. The result also shows that it is mainly the preschool teachers who describe technology in a more complex way. Many of the respondents have trouble separating technology from science, and quite a few describes technology as technique, which is another meaning for the word in the Swedish language.

This paper aims to evaluate the knowledge landscape of the phytoremediation of heavy metals (HMs) by constructing a series of scientific maps and exploring the research hotspots and trends of this field. This study presents a review of 6873 documents published about phytoremediation of HMs in the international context from the Web of Science Core Collection (WoSCC) (1989–2018). Two different processing software applications were used, CiteSpace and Bibliometrix. This research field is characterized by high interdisciplinarity and a rapid increase in the subject categories of engineering applications. The basic supporting categories mainly included “Environmental Sciences & Ecology”, “Plant Sciences”, and “Agriculture”. In addition, there has been a trend in recent years to focus on categories such as “Engineering, Multidisciplinary”, “Engineering, Chemical”, and “Green & Sustainable Science & Technology”. “Soil”, “hyperaccumulator”, “enrichment mechanism/process”, and “enhance technology” were found to be the main research hotspots. “Wastewater”, “field crops”, “genetically engineered microbes/plants”, and “agromining” may be the main research trends. Bibliometric and scientometric analysis are useful methods to qualitatively and quantitatively measure research hotspots and trends in phytoremediation of HM, and can be widely used to help new researchers to review the available research in a certain research field.

This inquiry aims to determine the ways and means through which the accuracy category manifests itself in the news genre and to identify internal contradictions formed by the interaction between logical and semantic components of the expression. The objectives were as follows: to determine how the accuracy category is presented through the categories of subject, time, and place of action, what are the transformative possibilities of these categories in the field of adequate transmission of meaning, which linguistic means actualize the accuracy category or, on the contrary, “blur” it. Continuous sampling, analysis and synthesis, transformational, and descriptive methods were used in the research process. We confirm that the subject in the headline is delivered explicitly and implicitly in the conclusions presenting the research results. “Nonsubjectivity” is realized using indefinite (non-personal) forms of the predicate or can be determined through a locus. For news headlines, the locus is an essential component, its place in the sentence can adjust the semantic accents of the statement. The time category in analyzed titles is almost always explicit. The accuracy category is most clearly manifested in direct indications of time and place and in two-syllable sentences where the subject of the action is specified.

This study makes a systematic review of scientific publications of research, on the theme Technology Park in Brazil. It seeks to identify and analyze the scope of Science and Technology Parks at the national level, in order to understand the trends and interrelations between university education. The mapping was the basis for knowing and discussing the results of the scientific production of different areas, considering the different times and places, in what form and under what conditions they were produced. For its construction, searches were carried out on the subject in the Capes, Bdtd, Anped and Ibict databases from 2006 to 2017, looking for similarity with a set of descriptors. The survey was performed after selection in the directories that indicate PCT as the subject of study. We retrieved 574 scientific research productions, being selected for reading the abstract 132 works, we observed that only 18 productions are preponderant in relation to the area of education. For the analysis, the following variables were considered: objective, methodology and conclusions pointed out, with the interest concentrated in university formation, scientific initiation, social impact, case study. To analyze the data, the following categories emerged: PCT and the relationship between university, business and government; PCT and Public policies; PCT and technological and economic development; PCT and management model and finally, PCT and the relationship with initiation. The analysis shows that researchers need to follow a planning and scientific strategy that allows them to present different levels of relationships between park and technology, innovation, economics, research, government, business, development and university. The result of the analysis of the categories on methodologies, indicated indications that are the methods and the technical instruments that order the systematized thought, organizing in a organized way the way of proceeding throughout the investigation to reach the proposed objective.

National research diversity is explored through the balance of global and national papers in journal categories in the Web of Science (WoS) and Essential Science Indicators (ESI) and we examine the consequences of “normalizing” national publication counts against global baselines. Global balance across subject categories became more even as annual WoS indexing grew fourfold between 1981 and 2018, with a relative shift from biomedicine towards environment and technology. Change at the country level may have tracked this or been influenced by local policy and funding. We discuss choice of methods and indices for analysis: WoS categories provide better granularity than ESI; Lorenz curves are explored but found limiting; the Pratt index, Gini coefficient, and Shannon diversity are compared. At the national level, balance generally increases and is greatest in non-Anglophone countries, perhaps due to shifts in language and journal use. Two aspects of national change are revealed: the balance of actual WoS paper counts and the balance of counts normalized against world baseline. The broad patterns for these analyses are similar, but normalized data indicate relatively greater evenness. National patterns link to research capacity and regional networking opportunities, while international collaboration may blend national differences. A data set is provided for analytical use.

The aerobic granular sludge (AGS) system is a promising technology that is suitable for the treatment of various types of wastewaters. This system has received great attention from many researchers due to its wide range of applications and potential as a cost effective system. However, only a few reports are available in analyzing the progress of AGS research in wastewater treatment over the last 20 years. Therefore, in the present work, a bibliometric analysis was carried out to trace the global research trends and current hotspots of AGS in wastewater treatment from 1997 to 2020, based on the Scopus database. The bibliometric data was visualized using the VOSviewer software. A total of 1,347 articles were published in 160 journals across 19 subject categories, involving 50 countries and 129 academic institutions. Results showed that Bioresource Technology (175, 12%), Water Research (94, 6.96%), and Huanjin Kexue Environmental Science (78, 5.77%) dominated in the top 3 journals. Environmental Science (1036, 38%), China (716, 53%), and Harbin Institute of Technology (98, 7.28%) were the most productive subject category, country, and academic institution, respectively. The AGS research hot topics and future research directions were discovered through the analysis of the most frequently used keywords obtained in bibliometric maps.

This study explores a bibliometric approach to quantitatively assessing current research trends on sludge, by using the related literature published between 2000 and 2011. The articles acquired from such literature were concentrated on the general analysis by publication type and language, characteristics of articles outputs, country, subject categories and the frequency of title-words used. Over the past 12 years, there had been a notable growth trend in publication outputs, along with more participation of countries/territories. An analysis of the title-words showed that wastewater treatment was still the most hot topic in sludge research and wastewater, heavy metal, waste water treatment and anaerobic digestion were recent major topics of sludge research. Besides, membrane bioreactor technology has been advancing rapidly around the world and became an ideal way to reduce sludge production in the wastewater treatment process.

The accuracy of the power battery model and SOC estimation directly affects the vehicle energy management control strategy and the performance of the electric vehicle, which is of great significance to the efficient management of the battery and the improvement of the reliability of the vehicle. Based on the research of domestic and foreign battery models and the previous results of SOC estimation, this paper classifies power battery models into electrochemical mechanism models, equivalent circuit models and data-driven models. This paper analyzes the advantages and disadvantages of various battery models and current research progress. According to the choice of battery model, the previous research results of the power battery SOC estimation method are divided into three categories: the direct measurement method not based on battery model, the estimation method using black box battery model, and the battery model SOC estimation method based on state space. This paper will summarize and analyze the principles, applicable scenarios and research progress of the three categories of estimation algorithms aiming to provide references for future in-depth research. Finally, in view of the shortcomings of the battery model and estimation algorithm of the existing method, the future improvement direction is proposed.

This study adopts an intersectional approach to explore the complexities and contingencies of subject positioning in the case of an individual older worker. Five deconstruction strategies are applied to an older worker’s account of his experience of the workplace to unveil the variety of discourses and taken-for-granted assumptions that regulate individual identity formation and contribute to perpetuating the marginalization of the aging organizational subject. Deconstruction analysis shows how the unique positioning of the research subject emerges at the intersection of complex discourses of age, enterprise, family, death, and mental and physical health, casting him as both victim and perpetrator of inequality across a kaleidoscope of interacting categories of oppression. The analysis contributes to the critique of the binary dualism implicit in the victim–perpetrator paradigm dominating mainstream research and policy making on age discrimination in the workplace. It also advocates for new conceptualizations of aging at work that recognize the systemic nature of inequality as the product of intersecting systems of power relations.

This paper aims to explore the current status, research trends and hotspots related to the field of infrared detection technology through bibliometric analysis and visualization techniques based on the Science Citation Index Expanded (SCIE) and Social Sciences Citation Index (SSCI) articles published between 1990 and 2018 using the VOSviewer and Citespace software tools. Based on our analysis, we first present the spatiotemporal distribution of the literature related to infrared detection technology, including annual publications, origin country/region, main research organization, and source publications. Then, we report the main subject categories involved in infrared detection technology. Furthermore, we adopt literature cocitation, author cocitation, keyword co-occurrence and timeline visualization analyses to visually explore the research fronts and trends, and present the evolution of infrared detection technology research. The results show that China, the USA and Italy are the three most active countries in infrared detection technology research and that the Centre National de la Recherche Scientifique has the largest number of publications among related organizations. The most prominent research hotspots in the past five years are vibration thermal imaging, pulse thermal imaging, photonic crystals, skin temperature, remote sensing technology, and detection of delamination defects in concrete. The trend of future research on infrared detection technology is from qualitative to quantitative research development, engineering application research and infrared detection technology combined with other detection techniques. The proposed approach based on the scientific knowledge graph analysis can be used to establish reference information and a research basis for application and development of methods in the domain of infrared detection technology studies.

Customers’ behavior in social networks is continually developing. Businesses are tracking the changes in the consumers’ preferences for the categories of their products, which is important for developing the effective promotion. The methods of studying the features of the consumers’ media behavior and media preferences for the different categories of goods in the social networks includes the following elements: relevance, subject, goals, and tasks of the research topic; characteristics of methods and technologies for collecting and analyzing the data; description of each stage of the research process; formulation of hypotheses on the correlation between consumers’ media behavior and media preferences in social networks and their interest in various categories of goods; technology for testing the hypotheses and processing survey results in the Statistical Package for the Social Sciences (SPSS); algorithm for developing proposals for promoting certain categories of goods in social networks. The methods are of interest and applicable for any business focusing on a certain category of goods. The methods were tested on the basis of empirical research in the form of a survey, the results of which allowed developing a set of proposals for promoting the top categories of goods, which are purchased on the Internet most often, in social networks. The set of proposals has been formed by selecting the core (a set of parameters common to the consumers of all goods) and peculiarities (features dominating in the characteristics of consumers’ behavior only for a certain category of goods) of consumers’ media behavior and media preferences in social networks.

There has been a large volume of research on structural health monitoring since the 1970s but this research effort has yielded relatively few routine industrial applications. Structural health monitoring can include applications on very different structures with very different requirements; this article splits the subject into four broad categories: rotating machine condition monitoring, global monitoring of large structures (structural identification), large area monitoring where the area covered is part of a larger structure, and local monitoring. The capabilities and potential applications of techniques in each category are discussed. Condition monitoring of rotating machine components is very different to the other categories since it is not strictly concerned with structural health. However, it is often linked with structural health monitoring and is a relatively mature field with many routine applications, so useful lessons can be read across to mainstream structural health monitoring where there are many fewer industrial applications. Reasons for the slow transfer from research to practical application of structural health monitoring include lack of attention to the business case for monitoring, insufficient attention to how the large data flows will be handled and the lack of performance validation on real structures in industrial environments. These issues are discussed and ways forward proposed; it is concluded that given better focused research and development considering the key factors identified here, structural health monitoring has the potential to follow the path of rotating machine condition monitoring and become a widely deployed technology.

The flow-matching problem of hydraulic systems is an important factor affecting the working performance and energy saving of hydraulic systems. According to the different flow-matching mechanisms, the flow-matching technology of hydraulic systems can be divided into three categories: positive flow-control technology, negative flow-control technology, and load-sensitive control technology. In this paper, the working mechanism of flow-matching technology and the cause of energy loss are analyzed, and the research results of flow matching are introduced from two aspects of energy saving and consumption reduction and system performance improvement. In the direction of energy saving and consumption reduction, the purposes of energy saving and consumption reduction are achieved by means of multi-way valve commutation, independent inlet and outlet control, parallel replacement of shuttle valve by a cylinder piston rod controlled by pilot pressure, change of hydraulic resistance of a pressure compensating valve, improvement of the power regulation range of a hydraulic pump, and potential energy recovery. In the direction of system performance, by means of flow-forecasting system pressure change, applying flow unsaturation real-time control idea, and combining electronic control technology with load-sensitive technology, the pressure drop during transmission process and the transmission signal lag are reduced, the speed regulation interval is enlarged, fine-tuning characteristics are improved, and the response speed is increased. The research results indicate that improving the structure and the control strategy of hydraulic systems and improving the flow-matching degree of a system to achieve global matching will be a future development trend.

This article critically reviews the literature on the economic benefits of publicly funded basicresearch. In that literature, three main methodological approaches have been adopted —econometric studies, surveys and case studies. Econometric studies are subject to certainmethodological limitations but they suggest that the economic benefits are very substantial.These studies have also highlighted the importance of spill over’s and the existence oflocalisation effects in research. From the literature based on surveys and on case studies, it isclear that the benefits from public investment in basic research can take a variety of forms. Weclassify these into six main categories, reviewing the evidence on the nature and extent of eachtype. The relative importance of these different forms of benefit apparently varies withscientific field, technology and industrial sector. Consequently, no simple model of theeconomic benefits from basic research is possible. We reconsider the rationale for governmentfunding of basic research, arguing that the traditional ‘market failure’ justification needs tobe extended to take account of these different forms of benefit from basic research. The articleconcludes by identifying some of the policy implications that follow from this review.

As one of the new liberal arts categories, law has always been a key subject of national legal construction. With the continuous development of science and technology and the rapid progress of society, enterprises' demand for legal talents has changed from single type to compound type. The current training mode of legal talents in our country cannot meet the needs of the rapid development of the society. In view of this, combined with the traditional theoretical teaching mode of talent training for law majors, the new talent training methods should be added to explore the suitable mode for the cultivation of innovative and entrepreneurial talent for law majors in China. Starting from the theory and practice, combining with the characteristics of each university, the ultimate goal is to cultivate the compound legal talents with innovative and entrepreneurial ability.

Purpose – This paper aims to examine two important factors in developing convergence products: the congruence of basic product and the addition in terms of utilitarian or hedonic consumption goals, and the overall coherence of consumption goals. In recent years, the proliferation of convergence products, i.e. any product that combines two or more basic product functionalities in consumer electronics, is increasingly prevalent. For manufacturers, the lingering question in developing convergence products is what kind of basic product functionalities can be combined and can elicit favorable response from consumers. Design/methodology/approach – The study is a 2 × 2 × 2 experimental design, with basic product functionality’s consumption goals (utilitarian, hedonic) as the between-subject factor, and the additional product functionality’s consumption goals (utilitarian, hedonic) and the coherence of consumption goals (coherent addition, incoherent addition) as the two within-subject factors. Findings – It confirms and validates prior work on goal congruence effects. More importantly, this study finds that overall consumption goal coherence elicits higher value addition irrespective of goal congruence or incongruence on utilitarian or hedonic consumption goals. Research limitations/implications – In some literatures, the combination of two or more product functionalities from different product categories is considered as product bundling. While product bundling concept can be used in many different product categories, convergence product concept is utilized more specifically in consumer electronics. Practical implications – As convergence era offers wide opportunities for manufacturers to develop new convergence products, this study provides guidance as to what kind of new functionalities need to be added. Originality/value – Not only does the present research investigates the likely success of convergence products involving the congruence of basic product and the addition, but also in more comprehensive way by looking at the overall coherence of consumption goals.

The current problems associated with the maintenance of hard coal longwall mining depend on the application or use of extraction technologies. In order to make the best use of these technologies, a new approach based on simulation studies is necessary. This paper aims to develop a mathematical model for the powered roof support’s operation. The three groups of professionals involved in the testing of the roof support were involved in the work on changing the hydraulic system of the powered roof support stand. These professionals were powered roof support’s designers, researchers and users. The research subject was the development of a mathematical model as a starting point for conducting simulations. The model is based on d’Alembert’s principle and the equation of the balance of flow rates. Based on the developed model, it is possible to determine the pressure in the space under the piston of the hydraulic prop. The results obtained in the simulations are the basic assumptions for the development of a prototype that would solve the current problems in the hydraulic systems of powered roof supports. The adopted research methodology assumed the development of a mathematical model, simulation in the MATLAB environment and verification of the model on a test stand. The obtained results of simulation tests based on the developed mathematical model were confirmed in bench tests. Simulation and bench tests determined the correctness of the assumptions made for the development of the prototype model. Based on the analysis of the results, the nature of the work of the future prototype has been predetermined. The next stage will be the testing of the prototype, which is to be included in the hydraulic system of the prop of powered roof support in the future. The model mentioned before is the baseline model, and it will be modified depending on the application of the future design in real conditions. Simulation studies of powered roof support will allow the structure that is used currently to be optimised, so as to adapt it to increasingly difficult working conditions.

ABSTRACTAntibiotic residues have entered into the environment owing to the unreasonable use and disposal of antibiotics. The emergence of antibiotic resistance poses a huge threat to ecosystems and human health. In this study, the network analysis method was used to compare publications on antibiotics in water, soil and sediment from the aspects of countries, institutes, journals, subject categories and keywords based on Web of Science Core Collection. The results indicated that the United States of America and China had dominant positions of studies on antibiotics. The Chinese Academy of Sciences published the most articles on antibiotic research. ‘Chemosphere’, ‘Science of the Total Environment’, ‘Environmental Science and Technology’ and ‘Applied and Environmental Microbiology’ all appeared in the top six journals. ‘Environmental Sciences and Ecology’ was the core subject category of antibiotic research. Further analysis results depicted that ‘Antibiotics’, ‘Tetracycline’ and ‘Antibiotic Resistance’ were found as the research hotspots. Tetracycline and oxytetracycline all showed in the top 50 keywords of antibiotics research in water, soil and sediment. However, chlortetracycline, sulfadiazine and tylosin all emerged only in the top 50 keywords of antibiotics study in soil. In future, more attention should be paid to antibiotic resistance genes and antibiotic resistance bacteria in antibiotics research.

Leisure motor activities are not a constant in the educational program of institutionalized children. In the context of several specialized studies suggesting that those who are raised in foster care have a slower or poorer physical development compared to those who grow up with their family, we have conducted a comparative study between a group of institutionalized children and a group of dancers, through which the level of motor development of the two categories could be established objectively. Given that dancesport is not yet used as a means of development and social integration for the children in orphanages, the purpose of this subject is to highlight the contribution of dancing to the psychomotor development of preadolescents. The results of the initial testing with the Optojump device indicate the effectiveness of dancesport in children from families. Thus, an intervention model was developed based on contents of dancesport, in order to stimulate the motor skills of institutionalized children. At the end of the research, significant differences were identified between the initial phase results and the final testing results.

Modern research in the field of sociology of science is becoming more complicated due to the constantly growing publication activity of authors. To track trends in sectoral sociology, scientists turn to scientometric methods, but they are not enough. Trends in the development of the sociology of values as a branch of sociology are the subject of the study. The purpose of the work is an assessment of the possibilities of using natural language analysis methods (NLP/NLA) for thematic and theoretical clustering of research in the sociology of values. The design of the study was quantitative and qualitative, it was carried out in two stages. At the first stage, 121 abstracts of a scientific articles were analyzed using text mining, after which their total array was divided into clusters. At the second stage, the results of machine clustering were examined by the method of qualitative text analysis, on the basis of which the limitations and capabilities of the NLP/NLA method were identified for solving the problem of clustering scientific texts. It was found that articles with a more conservative core of theoretical categories (gender studies, migration studies, the theory of globalism) are more amenable to clustering, while theories with a loosely structured and fluid theoretical core (theories using environmental terminology, theories of inequality) are much less amenable to explicit clustering. The results obtained allow us to form a new direction of work with large arrays of scientific texts, associated with their clustering using NLP/NLA. Building clusters enables researchers to work with all texts in a given subject area, and not just with the most cited ones. This, in turn, provides the visibility of all scientific ideas, including those that have not gained popularity/notability.

The influence of the family on business has been the subject of much debate, particularly with regard to the assumed familiness of family businesses. The term ‘familiness’ is at risk of becoming an umbrella concept and is often used haphazardly, lacking a solid theoretical background. This review provides a structured overview of the literature addressing the idea of familiness. Over the last 13 years, research on this key concept has grown continually, resulting in a broadening rather than a deepening of the concept of familiness. The results of the analysis of 33 manuscripts are presented and consolidated into three main categories: (1) theoretical perspectives; (2) the development and impact of familiness; and (3) empirical approaches. The analysis shows that existing research on familiness lacks the application of a universal theoretical lens. The authors counteract this shortfall by introducing new systems theory and presenting promising directions for further research, especially with regard to the development of a familiness typology.

As an essential factor of the earth’s critical zone, soil water has a remarkable influence on nutrient cycle and energy flow in terrestrial ecosystems and has attracted the attention of considerable scholars. Based on the online database of Web of Science, the bibliometric analysis was performed to evaluate the evolution feature of soil water research from 1934 to 2019. The results showed a rapid growth of scientific outputs with a gradually increasing proportion of internationally collaborative articles. Environmental Sciences, Water Resources, and Soil Science were the most frequently used subject categories, and the Journal of Hydrology had the highest number of publications in this field. The institutions from the USA and China were the most active, and the USA occupied a leading position in soil water research, producing the most articles and having the most considerable number of citations. Clusters of authors were mostly located in North America, Western Europe, West Asia, and East Asia. Keywords analysis demonstrated that climate change, drought, evapotranspiration, remote sensing, and irrigation were the current research hotspots. Scientific issues focusing on the interaction between soil water and environmental factors, drought forecast, relationships between soil structure and water/solute transport, improving the accuracy and depth of soil moisture monitoring with satellite, and spatio-temporal scaling transform require further research.

With the development of mobile network technology and the popularization of mobile terminals, traditional information recommendation systems are gradually changing in the direction of real-time and mobile information recommendation. Information recommendation brings the problem of user contextual sensitivity within the mobile environment. For this problem, first, this paper constructs a domain ontology, which is applicable to the contextual semantic reasoning model. Second, based on the “5W + 1H” method, this paper constructs a context pedigree of the mobile environment using a model framework of a domain ontology. The contextual factors of the mobile environment are divided into six categories: the What-object context, the Where-place context, the When-time context, the Who-subject context, the Why-reason context, and the How-effect context. Then, considering the degree of influence of each contextual factor from the mobile context pedigree to the user is different, this paper uses contextual conditional entropy to calculate the contextual weight of each contextual attribute in the recommendation process. Based on this, a contextual semantic reasoning model based on a domain ontology is constructed. Finally, based on the open dataset provided by GroupLens, this paper verifies the validity and efficiency of the model through a simulation experiment.

This study focuses on the content of technology-related courses offered by teacher training institutions to determine the factors that will avoid technology integration in teacher education/training. Two methods are combined in the research. As a first step, the integration of technology in education/teaching models literature was analyzed, synthesized, and categories were created based on the critics. Next, technology-related courses in teacher training curricula were defined, the content of those courses was analyzed, and some content and suggestions were proposed for better technology-integrated courses. Even though literature indicates the most critical barriers to technology integration in education are hardware problems and the lack of technical infrastructure, one of the underlying factors is the teachers' inadequacy in ICT, the usage of technology in education, and technology integration literacy. These inadequacies are the result of the training curriculum deficiencies. There are three suggestions based on the findings and for further studies. The first one is to add courses and contents to the teacher-training curriculum as discussed in interpretation and discussion. Secondly, instructional technology courses should have specific content related to the content area. The syllabus should be developed with the cooperation of the content area teacher trainer for each subject area. Finally, as a part of curriculum development, these proposed courses and their content should be reevaluated for further studies.

Abstract. Geomorphometry, the science of quantitative land-surface analysis, has become a flourishing interdisciplinary subject, with applications in numerous fields. The interdisciplinarity of geomorphometry is its greatest strength and also one of its major challenges. Gaps are still present between the process focussed fields (e.g. soil science, glaciology, volcanology) and the technical domain (such as computer science, statistics …) where approaches and theories are developed. Thus, interesting geomorphometric applications struggle to jump between process-specific disciplines, but also struggle to take advantage of advances in computer science and technology. This special issue is therefore focused on facilitating cross-fertilization between disciplines, and highlighting novel technical developments and innovative applications of geomorphometry to various Earth-surface processes. The issue collects a variety of contributions which fall into two main categories: Perspectives and Research, further divided into “Research and innovative techniques” and “Research and innovative applications”. It showcases potentially exciting developments and tools which are the building blocks for the next step-change in the field.

Introduction. Modern study of terminologies and term systems are carried out in the aspect of cognitive terminology. Research devoted to the study of the term semantics in the context of cognitive terminology is gaining popularity.The aim of the work is to create frame models of the term semantics of the subject area “Construction Technologies”, to identify the main cognitive categories and subcategories represented by these models and characteristic of construction terminology, as well as the means of their expression.Material and methods. The material for the study is the terms of the sphere of construction technologies, selected from the terminological dictionaries on construction, regulatory documents, educational and scientific literature, as well as catalogues of construction products and professional websites for construction engineers. The research methodology is based on the method of linguistic modeling, frame analysis was used to study the term semantics. The techniques of definitional and component analysis are also used.Results and discussion. The frame modeling of the term semantics of the professional field “Construction technologies” was performed on the basis of the word-formation structure of the derived term. As a result of the analysis of frame models, correlated with the word-forming types, the following cognitive categories in the terminology of the sphere of construction technologies are defined: “process”, “attribute”, “ability / characteristic”, “action”, “object”.The article provides a detailed analysis of the semantics of Russian terms that actualize the cognitive categories “process” and “feature”. Frame models of term semantics are proposed; the frame consists of slots, which are components of the meaning of the term and are represented by various morphemes. The categorical slot is of particular importance as it correlates with the part-of-speech belonging of the term.The following subcategories specify the semantics of the identified cognitive categories: “technology of manufacturing / application of building materials”, “stage of the technological process”, “special construction works / results of these works”, “construction defect”, etc. These subcategories are defined by the specifics of the terminology of the field of construction technologies.Conclusion. As a result of frame modeling the semantics of the terms of the sphere “Construction technologies” and the analysis of the cognitive categories “process” and “attribute”, within each of them, subcategories specific to construction terminology were identified. It was revealed that the most productive way of word formation in the analyzed terminology is suffixation and prefixation. The proposed frame models of terms reflect fragments of scientific knowledge verbalized by special nominations, and frame analysis is an effective method for studying the ways of categorizing scientific information.

Urban resilience (UR), which promotes the implementation of resilient cities, has received widespread attention. The purpose of this study is to visualize the knowledge background, research status, and knowledge structure of relevant literatures by using a Citespace based scientometrics survey. The results show that UR is an increasingly popular topic, with 2629 articles published during the study period. (1) The most prolific publications and journals involved in the flourishment of UR research were identified by co-citation. The United States was the most productive contributor, with numerous publications and active institutions. Journal of Cleaner Production, Sustainability, International Journal of Disaster Risk Reduction were the three most cited journals. (2) Co-occurrence analysis was employed to determine the highly productive keywords, and subject categories in the UR domain, including “environmental science & ecology”, “environmental sciences, “science & technology”, “environmental studies”, “green & sustainable science & technology”, and “water resources”. (3) The diversity of highly cited authors in different countries and regions confirmed the evolution of UR studies. (4) Furthermore, the classification of UR knowledge was performed in the form of clusters and knowledge structure to achieve ten distinct sub-domains (e.g., Urban floods and stormwater management, Urban ecosystem services, Urban landscapes, and Trauma). This study provides an overview of UR research and research topics so that future researchers can identify their research topics and partners.

Objectives:The aim of this study was to assess whether publications of importance for improving the health system and its technologies are highly cited intrascientifically.Methods:Bibliometric assessment of the 596 publications used as sources in the fifty SBU Alerts from 2001to 2004 from the Swedish Council on Technology Assessment in Health Care was carried out using the Thomson Scientific citation indexes. Normalized citation scores were calculated for all included studies. Additional factors such as the time and place of the research, subject categories, and journal source were analyzed.Results:On average, the sources in SBU Alert have been cited eight times more than the world average consistently during the time period and across research areas. Articles used as its scientific basis are often published in a few, high impact, general medical journals. However, many of the articles are published in field-specific journals with low impact factors. Most articles used in SBU Alert are published by authors based in the United States or the United Kingdom. However, Swedish, Danish, and Dutch publications are overrepresented in its science base, whereas Japanese, Taiwanese, Indian, and Russian publications are underrepresented.Conclusions:Publications used as sources in a Swedish system for identification and early assessment of new methods in health care are also highly cited within the scientific community. This finding increases the appropriateness of using bibliometric indicators in evaluations of clinical research and suggests that decision makers through SBU Alert are getting scientifically sound advice.
