Purpose:The goal of this study is to analyze the relationship between funded and unfunded papers and their citations in both basic and applied sciences.Design/methodology/approach:A power law model analyzes the relationship between research funding and citations of papers using 831,337 documents recorded in the Web of Science database.Findings:The original results reveal general characteristics of the diffusion of science in research fields:a)Funded articles receive higher citations compared to unfunded papers in journals;b)Funded articles exhibit a super-linear growth in citations,surpassing the increase seen in unfunded articles.This finding reveals a higher diffusion of scientific knowledge in funded articles.Moreover,c)funded articles in both basic and applied sciences demonstrate a similar expected change in citations,equivalent to about 1.23%,when the number of funded papers increases by 1%in journals.This result suggests,for the first time,that funding effect of scientific research is an invariant driver,irrespective of the nature of the basic or applied sciences.Originality/value:This evidence suggests empirical laws of funding for scientific citations that explain the importance of robust funding mechanisms for achieving impactful research outcomes in science and society.These findings here also highlight that funding for scientific research is a critical driving force in supporting citations and the dissemination of scientific knowledge in recorded documents in both basic and applied sciences.Practical implications:This comprehensive result provides a holistic view of the relationship between funding and citation performance in science to guide policymakers and R&D managers with science policies by directing funding to research in promoting the scientific development and higher diffusion of results for the progress of human society. 展开更多

According to the definition, seismology is a science that studies the processes and causes of seismic phenomena and the structure of the Earth, i.e. a scientific discipline that studies the movement of blocks of rocks of the Earth’s crust and mantle and related phenomena. Seismology conducts research in the following areas and is designed to scientifically explain two main issues: 1) Study of the nature of seismic phenomena and the internal structure of the Earth. Why, how and where do seismic impacts occur? 2) Protecting humanity from the catastrophic consequences of seismic events. Is it possible to predict seismic impacts? Like any other scientific discipline, seismology is obliged to follow the laws of science and its fundamental principles. This article is devoted to the description of violations of the fundamental laws of science committed by seismologists in the study of seismic processes and raises the question of compliance of the stated research directions with the current level of development of sciences. Answering point No. 1, regarding the structure of the Earth, it is possible to recognize some successes of seismology, which nevertheless cause great doubts in the scientific community of geophysicists, because if the stratigraphic data of ultra-deep wells often refute [1] the conclusions made by seismologists on the structure of the Earth’s crust at shallow depth, then to assert something unambiguously about the structure of the mantle and at the present stage, seismology cannot. Answering the main questions of seismology, why seismic phenomena occur, and how earthquake energy is formed, seismologists have not had, and have not. Answering point No. 2, we can confidently say that in the matter of forecasting seismic phenomena, seismology has not advanced one iota over the past century, and as seismologists have been confused in the search for earthquake prediction algorithms, they are also confused without any hope of success. All that modern seismology can “boast” is the theory of Elastic recoil [2], the absurdity of which does not cause any doubt among the progressive part of geophysicists. But, the fact that most of the leading scientists-seismologists continue to piously believe the conclusions of the Elastic Recoil theory puts seismology in a humiliating position, because Mr. Reid’s theory is the clearest example of a false theory based on scientific incompetence of scientists, a model of brazen violation of the fundamental laws of science and the foundation of false and ignorant conclusions. Based on the results achieved, or rather on their absence, we regret to draw a sad conclusion: modern seismology is in the deepest decline, the cause of which is the incompetence of researchers as a result of their catastrophically low level of academic training, who stuff the scientific community with scientific geophysical rubbish, breeding similar ignoramuses in seismology. We understand that by asserting this, we offend most seismologists, but it is impossible to continue to tolerate this state of affairs in geophysics, because: “Amicus plato, sed magis amica est veritas.” Obviously, the time has come for a new meteorologist, Alfred Wagener [3], who will come and teach seismologists not to guess on coffee grounds, but to investigate seismic processes using the fundamental laws of science. In this article, we not only investigate the reasons for the unsatisfactory state of affairs in seismology, but also give our answers to the questions, of why earthquakes occur and how seismic energy is formed. 展开更多

Ni-Ti-based shape memory alloys(SMAs)have found widespread use in the last 70 years,but improving their functional stability remains a key quest for more robust and advanced applications.Named for their ability to retain their processed shape as a result of a reversible martensitic transformation,SMAs are highly sensitive to compositional variations.Alloying with ternary and quaternary elements to finetune the lattice parameters and the thermal hysteresis of an SMA,therefore,becomes a challenge in materials exploration.Combinatorial materials science allows streamlining of the synthesis process and data management from multiple characterization techniques.In this study,a composition spread of Ni-Ti-Cu-V thin-film library was synthesized by magnetron co-sputtering on a thermally oxidized Si wafer.Composition-dependent phase transformation temperature and microstructure were investigated and determined using high-throughput wavelength dispersive spectroscopy,synchrotron X-ray diffraction,and temperature-dependent resistance measurements.Of the 177 compositions in the materials library,32 were observed to have shape memory effect,of which five had zero or near-zero thermal hysteresis.These compositions provide flexibility in the operating temperature regimes that they can be used in.A phase map for the quaternary system and correlations of functional properties are discussed w让h respect to the local microstructure and composition of the thin-film library. 展开更多

With the continuous development of science and technology, the academic communication of many scholars slowly shifts to the web, and people’s academic communication in social media gradually increases. Traditional metrics have a certain one-sidedness in the evaluation of disciplinary literature and cannot evaluate the impact of literature on the web;while Altmetrics can count how literature is followed and utilized on the web, which is a complement to the traditional measurement methods. Therefore, it is necessary to evaluate the impact of academic literature based on Altmetrics, and combining it with traditional citation indicators can strengthen the credibility and objectivity of academic evaluation and promote better dissemination and communication of academic results. Against this research background, this paper combed through the most influential articles in the field of library and information science in recent years, analysed the literature on library intelligence in the WOS database, identified current research hotspots in the field of library and information science, and predicted potential research hotspots in the future. This study may provide a reference for the research and development of the discipline. 展开更多

This paper deals with the educational role of library, especially university library, and in connection to this, information literacy, competence, and standards in information science. Microcomputers and their current application allow students to use them in laboratories, lecture halls, and libraries;software that are so developed that they allow to various types of computers (micros, picos, or hand-held computers) easy integration with larger systems. In this context libraries, as institutions become one of several available nodes in the information network, the new organization of teaching requires that teachers and students are computer literate requires libraries to provide methods and techniques for handling, through expert systems, their diverse searches, and similar (video disc, for example). Along with terms informatics and information science, there is also the term informatology which denotes theory and practice of emission, transmission, accumulation, selection, and absorption of information, the so-called ETAKSA complex. This paper, therefore, will be discussed communication and communication processes in university libraries that take place using new types of media, which we jointly referred to as information science and in the sea of definitions;we can say that we have added another. 展开更多

More than twenty years ago,Wuhan University and Nanjing University offered library science(LS)graduate programs.Since then,LS graduate education has been growing quickly in many aspects.At the same time,however,LS graduate education was also facing enormous challenges stemming from the dynamic development and wide applications of information technologies into the pedagogical arena of teaching and learning at all levels.Social evolution also made it necessary for LS educators to re-examine once again their graduate education model,curricular composition,educational philosophy and educational missions.In analyzing the present situation of LS graduate education in China,this paper focuses on the following issues:1)Growing size of LS graduate education(quantity and quality);2)educational objectives,including research direction and placement for graduates;3)structure of knowledge and curricular construction;4)conditions of administering a library school of high quality and 5)the management of teaching resources.The keystone of this paper is to pinpoint where current library science curricular deficiencies are lying.It is hoped that more serious scholarly discussions and perhaps also even concerted efforts among LS scholars and library practioners may be evoked in having the graduate education system of library and information science thoroughly realigned for the informational needs of the 21st century. 展开更多

The history of science and medicine has long been steeped in the notion that they are objective(untainted by the philosophical and ideological ebbs and flows of society)and utilitarian(doing what is best for the greater good).Because of this,scientific and medical epistemologies and praxis are often held to an esteem that is unquestioned,celebrated,and occasionally unchecked.A closer look at the history of science and medicine,however,readily reveal the extent to which the milieu of society has informed scientific and medical endeavors.As such,an understanding of how the subjectivities of scientific and medical endeavors situate within our contemporary disciplines and practices is significant to one’s ability to truly understand said disciplines.Likewise,such an evaluation will provide insight into our role in perpetuating the illusion of objectivity in these fields.With this in mind,this paper provides a philosophical and historical examination of the concept of objectivity(in contrast to subjectivity)in science and medicine. 展开更多
