description: Ce travail traite de la manière dont l’environnement scolaire touche directement ou indirectement un élève dans son apprentissage. L’environnement est composé d’objets, de mobilier, de couleurs, de la gestion de l’espace, et ce dans les salles de classes, mais aussi ailleurs dans le bâtiment dans ce que j’appelle les espaces informels d’apprentissage. Ce travail comporte un historique de la fonction des bâtiments scolaires et un essai de prospective sur l’évolution de l’école. Nous identifions les freins à l’apprentissage, ainsi que les opportunités, souvent à portée de main, mais inexploitées à cause d’une négligence ou d’un manque de connaissance sur le potentiel bénéfice des espaces dans lequel l’apprentissage s’effectue. Des études ont démontré qu’aménager convenablement l’espace de la classe pouvait augmenter les résultats scolaires à hauteur de 16%. D’autres études ont démontré comment certains lieux peuvent impacter positivement comme négativement les élèves et qu’il est possible de réduire, entre autres, la violence et les tensions dans un établissement par une meilleure prise en compte de l’environnement scolaire. Ce travail développe tout un certain nombre de solutions pour des problèmes précis, ainsi que pour des problèmes généraux et explique comment et pourquoi il est nécessaire que les différents acteurs de l’école collaborent entre eux.

description: In this paper, the dynamic modeling of a seven linked humanoid robot, is accurately developed, in the three dimensional space using the Newton-Euler formalism. The aim of this study is to provide a clear and a systematic approach so that starting from generalized motion equations of all rigid bodies of the humanoid robot one can establish a reduced dynamical model. The resulting model can be expended either for simulation propositions or implemented for any given control law. In addition, transformations and developments, proposed here, can be exploited for modeling any other three-dimensional humanoid robot with a different morphology and variable number of rigid bodies and degrees of freedom.

description: Our previously proposed OFDM with sufficient cyclic prefix (CP) synthetic aperture radar (SAR) imaging algorithm is inter-range-cell interference (IRCI) free and achieves ideally zero range sidelobes for range reconstruction. In this OFDM SAR imaging algorithm, the minimum required CP length is almost equal to the number of range cells in a swath, while the number of subcarriers of an OFDM signal needs to be more than the CP length. This makes the length of a transmitted OFDM sequence at least almost twice of the number of range cells in a swath and for a wide swath imaging, the transmitted OFDM pulse length becomes long, which may cause problems in some radar applications. In this paper, we propose a CP based OFDM SAR imaging with arbitrary pulse length, which has IRCI free range reconstruction and its pulse length is independent of a swath width. We then present a novel design method for our proposed arbitrary length OFDM pulses. Simulation results are presented to illustrate the performances of the OFDM pulse design and the arbitrary pulse length CP based OFDM SAR imaging.

Tracing Scientific Trends: Scientometrics Methods and Metrics, and the Change in Librarians’ Roles
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: Along with the growth of science domains, scientific publications are also rapidly developing and as a result of this growth, tracing research trends in various domains of science becomes more difficult. The main use of tracing research trends by scientometrics methods and metrics is in assessment and evaluation of information resources. This paper reviews various methods of tracing the due trends (including peer review, bibliometric methods, web-based methods, and social networks, altmetrics) and studies the role of librarians in using and developing different criteria for monitoring and evaluating the process of science production. The results show that metrics for measuring the scientific impact should be created and developed in consistance with the development of scientific environment. As a result, librarians should develop new methods to carry out their role as scholarly communication specialists.
Adaptive Learning Systems Personalization Optimization Gravitational Search Algorithm
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: One of the main research areas is providing adaptive learning systems with new style for content delivery to users. Content delivery subsystem manages and selects the appropriate contents based on the user model. In order to realize the adaption and personalization, selecting approach should consider the learning capabilities and background knowledge of the learners. Therefore an optimization problem is defined and the system must optimize the difference between the learning capabilities and the learning style of the learner with the difficulty level and the presentation style of the delivered contents. This paper has focused on two aspects. In the problem modeling section, the previous defined model has been extended. The presented model has also considered the adaption between the learning style of the learner and the presentation style of the delivered contents. In problem solving section, this paper has applied two newer optimization algorithms, NBPSO and GSA, thus resulting in producing better answers (more appropriate and more adaptive selection of content). Also, according to the previous approaches, the problem has implemented and solved using PSO. The provided results of three algorithms have been evaluated using two well-known criteria: accuracy (aiming to measure optimality of the delivered answer) and stability (to ensure of getting answer in different performances). The results showed considerable progress (more personalized and adaptive contents).

description: Silicene, a hexagonal buckled 2-D allotrope of silicon, shows potential as a platform for numerous new applications, and may allow for easier integration with existing silicon-based microelectronics than graphene. Here, we show that silicene could function as an ultrafast electrical DNA sequencing device. We investigated the stability of this novel nano-bio system, its electronic properties and the pronounced effects on the transverse electronic transport, i.e., changes in the transmission and the conductance caused by adsorption of each nucleobase, explored by us through the non-equilibrium Green's function method. Intriguingly, despite the relatively weak interaction between nucleobases and silicene, significant changes in the transmittance at zero bias are predicted by us, in particular for the two nucleobases cytosine and guanine. Our findings suggest that silicene could be utilized as an integrated-circuit biosensor as part of a lab-on-a-chip device for DNA sequencing.
Surveying The Value of Knowledge Resources based on the Importance Factor (Backward-looking Factor, Forward-looking Factor): Case Study of Patents
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: This study aimed at analyzing the impact and importance of power and electronics patents in technology development. Citation analysis was used as the research method, using the especial formulas of the forward-looking and backwardlooking measures. The research population includes all patents in the field of power and electronics recorded from 1987 to 2006 in the USPTO. Analyzing the importance of patents in knowledge flow and their past and future effect on technology development indicated that at least 10 years should be passed from their release in order to their real effect on technology be seen. The mean of generality grade to determine the effect and application of patents in different subject areas showed that in addition to patents’ effect in electronics field, they have a high tendency to have relations with other subject areas. It was also found that there existed a significant relation between forward and backward looking measures, showing the dependence of future effect of a patent to its backward citations.

description: We report the first results from a spectroscopic survey of the [CII] 158um line from a sample of intermediate redshift (0.210^11.5 Lsun), using the SPIRE-Fourier Transform Spectrometer (FTS) on board the Herschel Space Observatory. This is the first survey of [CII] emission, an important tracer of star-formation, at a redshift range where the star-formation rate density of the Universe increases rapidly. We detect strong [CII] 158um line emission from over 80% of the sample. We find that the [CII] line is luminous, in the range (0.8-4)x10^(-3) of the far-infrared continuum luminosity of our sources, and appears to arise from photodissociation regions on the surface of molecular clouds. The L[CII]/LIR ratio in our intermediate redshift (U)LIRGs is on average ~10 times larger than that of local ULIRGs. Furthermore, we find that the L[CII]/LIR and L[CII]/LCO(1-0) ratios in our sample are similar to those of local normal galaxies and high-z star-forming galaxies. ULIRGs at z~0.5 show many similarities to the properties of local normal and high-z star forming galaxies. Our findings strongly suggest that rapid evolution in the properties of the star forming regions of luminous infrared galaxies is likely to have occurred in the last 5 billion years.

description: We studied SNS- and S-N-S-N-...-S contacts (where S - superconductor, N - normal metal) formed by "break-junction" technique in polycrystalline Sm$_{1-x}$Th$_x$OFeAs superconductor samples with critical temperatures $T_C = (34 ÷45)$ K. In such contacts (intrinsic) multiple Andreev reflections effects were observed. Using spectroscopies based on these effects, we detected two independent bulk order parameters and determined their magnitudes. Theoretical analysis of the large and the small gap temperature dependences revealed superconducting properties of Sm$_{1-x}$Th$_x$OFeAs to be driven by intraband coupling, and $\sqrt{V_{11}V_{22}}/V_{12} \approx 14$ (where $V_{ij}$ - electron-boson interaction matrix elements), whereas the ratio between density of states for the bands with the small and the large gap, $N_2/N_1$, correspondingly, was roughly of an order. We estimated "solo" BCS-ratio values in a hypothetic case of zero interband coupling ($V_{i \ne j} = 0$) for each condensate as $2Δ_{L,S}/k_BT_C^{L,S} \le 4.5$. The values are constant within the range of critical temperatures studied, and correspond to a case of strong intraband electron-phonon coupling.

description: Libraries operate in a competitive environment, and this is essentially needed to prove its benefits for stockholders, and continuously evaluate and compare advantages for printed and electronic resources. In these cases, economic evaluation methods such as cost- effectiveness analysis, is one of the best methods, because of a comprehensive study of the use and cost of library sources. The purpose of this study is to discovery of use and cost- effectiveness analysis of English printed and ebooks at University of Tehran on 2011. Populations of this study are English printed books which have been bought in 23th international Tehran book fair, and Elsevier and Springer ebooks collection. The result showed that the use of English printed books has different in four subject areas of Engineering, Sciences, Social and Behavioral Sciences, and Humanities, unlike English ebooks. The average of use of the printed books in Social and behavioral sciences Was 1.09, and it shows the most among all, and for Sciences, was only 0.14, this is the minimum among. 20 percent of English printed books have been used and the mean for total printed books was 0.77. 52 percent of ebooks have been used, and the average of use of ebooks was 5.16, respectively. So the use and cost- effectiveness analysis of English ebooks are more than English print books. The uses statistics and cost analysis showed that cost per use for English printed books is 787168 Rial and for ebooks is 80,388.

description: Au cours de sa carrière, il arrive que l’enseignant de français se trouve confronté à un dilemme cornélien : est-ce que le respect de la règle est plus important que la créativité littéraire ? En effet, la littérature se permet régulièrement de détourner et de se jouer des règles du français dans un but créatif, ludique, humoristique ou surprenant, alors que des détournements similaires dans une production écrite d’élève seront considérés (certainement plus à raison qu’à tort) comme des maladresses au mieux et sanctionnés d’une perte de points. Cette tension entre la nécessité scolaire et le plaisir de la littérature est difficile à résoudre, mais l’hypothèse présentée est qu’en travaillant avec les élèves le détournement des règles, il est possible de discuter cette tension et peut-être l’atténuer, en revalorisant certaines erreurs par exemple, mais également d’aborder la question de la créativité en jouant avec les règles et, par la modification du statut de la règle passant de but de l’enseignement à moyen de création, d’influer sur la motivation des élèves. Le présent travail, sur la base d’entretiens avec quatre enseignants de français, propose donc une réflexion sur les pratiques de l’enseignement du détournement des règles et sur la créativité : quelle place est-elle accordée à l’enseignement du détournement de la règle ? Quel impact un tel enseignement peut-il avoir sur les élèves et leur motivation ? Comment enseigner la créativité ? Sur la base des réponses apportées, ce mémoire présente quelques suggestions didactiques sur la manière d’intégrer le détournement de la règle dans l’enseignement du français.

description: We discuss the exit probability of the one dimensional $q$-voter model and present tools to obtain estimates about this probability both through simulations in large networks (around $10^7$ sites) and analyticaly in the limit where the network is infinetely large. We argue that the result $E(ρ) = \frac{ρ^q}{ρ^q + (1-ρ)^q}$, that was found in 3 previous works (2008 EPL 82 18006 and 2008 EPL 82 18007, for the case $q=2$ and 2011 PRE 84 031117, for $q>2$) using small networks (around $10^3$ sites), is a good approximation, but there are noticeable deviations for larger system sizes. We also show that, under some simple and intuitive hypothesis, the exit probability must obey the inequality, $\frac{ρ^q}{ρ^q + (1-ρ)} \leq E(ρ) \leq \fracρ{ρ+ (1-ρ)^q}$, in the infinite size limit. We believe this settles in the negative the suggestion made (2011 EPL 95 48005) that this result would be a finite size effect, with the exit probability actualy being a step function. We also show how the result, that the exit probability cannot be a step function, can be reconciled with the Galam unified frame, which was also a source of controversy.

An 8 week neuromuscular training programme reduces the risk of ACL injury and increases athletic performance variables in female court sport athletes
Creators: name: Morrow, Ryan
Publisher: name: University of Lincoln
Year: 2023

description: Court sport athletes repetitively perform movements which require physical attributes such asagility, acceleration, muscular power, muscular strength and balance. Unfortunately, some ofthe movements performed by court sport athletes such as changing direction quickly,decelerating and landing from a jump put athletes at an increased risk of injury their anteriorcruciate ligament. Females in particular are at an increased risk of injuring this ligament incomparison to their male counterparts. The purpose of this study was to investigate if aneuromuscular training protocol increased athletic performance variables and reduced the riskof ACL injuries in female court sport athletes. Twenty female court sport athletes took part inthis study (stature: 169 ± 7 cm, mass: 61.3 ± 8.3 kg, age: 22.3 ± 2.0 years, competitive playingexperience: 5.4 ± 1.6 years). Participants were split evenly through random allocation,comprising of ten in the control group and ten in the intervention group.Both the control and intervention groups pre-tests involved a 20 m sprint, counter-movementjump (CMJ), Illinois agility test and the Qualitative Analysis of a Single Leg Squat (QASLS),which is an assessment used to profile a participant’s risk of an ACL injury. After the pre-teststhe intervention group engaged in a modified version of the Fifa 11+ neuromuscular trainingprogramme twice a week over an eight week period. During this eight week period both groupswere instructed to continue with their habitual training regimes as delivered to them by theirsport coaches. After eight weeks both the control and intervention group participants wererecalled to repeat the pre-test protocols.A 2 (Control vs. Intervention) x 2 (Pre vs. Post – within subjects) mixed ANOVA demonstratedsignificant improvements for the intervention group’s CMJ (9.7% improvement) and QASLS(117% improvement on left leg and 65% on the right) in comparison to the control groupfollowing the training intervention. No significant differences between the two groups werefound for the Illinois agility test and 20 m sprint. However, there was a within-groupimprovement in 20 m sprint for the intervention group post training (2.2% decrease). Theresults demonstrate a modified Fifa 11+ protocol can be considered an effective neuromusculartraining programme for reducing the risk of ACL injuries and improving athletic performancevariables in female court sport athletes.

description: In classical superconductors an energy gap and phase coherence appear simultaneously with pairing at the transition to the superconducting state. In high-temperature superconductors, the possibility that pairing and phase coherence are distinct and independent processes has led to intense experimental search of their separate manifestations, but so far without success. Using femtosecond spectroscopy methods we now show that it is possible to clearly separate fluctuation dynamics of the superconducting pairing amplitude from the phase relaxation above the critical transition temperature. Empirically establishing a close correspondence between the superfluid density measured by THz spectroscopy and superconducting optical pump-probe response over a wide region of temperature, we find that in differently doped Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} crystals the pairing gap amplitude monotonically extends well beyond T_{c}, while the phase coherence shows a pronounced power-law divergence as T\rightarrow T_{c}, thus showing for the first time that phase coherence and gap formation are distinct processes which occur on different timescales.
Analysis and Comparison of the Use of Subscribed Electronic and Print Journals by Faculty Members and Postgraduate Students of Science School, University of Shiraz
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: The present study intended to analyze and compare electronic and printed journals usage by faculty members and postgraduate students of Shiraz School of Science. This research is of a descriptive and survey type. A questionnaire was used to collect data. The study population included 65 faculty members and 130 postgraduate students in Shiraz School of Science in the 2009-2010 academic year. The results of the study showed that both faculty members and postgraduate students make use of e-journals more than printed journals. Comparisons between the two cases reveal that faculty members make more use of e-journals than postgraduate students. Both groups confirm the importance of each of printed and electronic journals at “high” level but faculty members regard e-journals as more important and prefer use of e-journals. 79.9% of respondents believe that electronic form is a suitable substitute for printed form of journals. The findings also show that e-journals and printed journals meet the information needs of respondents respectively at “high” level and less than “average level”. Respondents introduce finding specific information, authoring and translating book and papers, and conducting research as their most important reasons in using both formats of journals. The most notable obstacles towards making optimum use of e-journals in view of respondents are not being informed of existence of required e-journals, lack of information about the resources available at e-journal databases and absence of the e-journals related to their fields of study. Although respondents totally declare their skill in making use of e-journals at “fairly high” level, faculty members are more skilled than postgraduate students. Generally, 64.4% of respondents are in need of learning use of e-journals while postgraduate students seem to be more in need of such a skill.

description: This study aims to shed light on the status of Persian thesauri of Humanities and to evaluate them in terms of four dimensions of form construction, semantic relationships, displaying controlled vocabularies, and management systems, based on the latest version of the ANSI/NISO z39.19 2005 standard. The research method utilized in this study is the analytical survey method. Systematic sampling method was used to select samples of the terms contained in the latest edition of every thesaurus in the field of Humanities except Islamic sciences thesauri. So the number of thesauri in this study was 3, and they were ASFA, UNESCO and thesaurus of Sociology. The research instrument used in this study was a check list defined in Microsoft Excel. The samples for the four dimensions were entered in the checklist and were evaluated on the basis of the relevant standards. The results of the study shows that the level of observance of semantic relations standards in ASFA, UNESCO and thesaurus of Sociology were respectively 93%,99% and 99%.The level of observance of form construction standards in ASFA, UNESCO and thesaurus of Sociology were respectively 99%, 99.5% and 96%. The level of observance of the standards in ASFA, UNESCO and thesaurus of Sociology was respectively With regard to displaying controlled vocabularies dimension were respectively 84%, 43% and 54.5% and the level of observance of management system standards in ASFA was 82% while the rate of this dimension in the remaining two thesauri was 14%. Finally, it is concluded that possessing the required expertise, familiarity with the standards of thesauri construction, utilizing appropriate models, taking the needs of the end users into consideration, reviewing and revising information storage and retrieval policies, and activation of the indexing and the reference sections of the libraries for registering the users' documents are among the major factors that if observed can lead to the construction of more effective and efficient thesauri.

The investigations are based on Debrecen sunspot data and magnetic field data of Mount Wilson. The recently available data and distributions seem to support the idea that the torsional wave may be caused by flows around the toruses which result in Coriolis-deviations forward and backward, establishing the prograde and retrograde belts.

Analyzing IS User Requirements using Organizational Semiotics
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: In recent years, lack of appropriate understanding of IS user requirements, has been one of the most important causes of IS development failure. Therefore, many methods were introduced for better analyzing user requirements some of them were philosophically different. Organizational semiotics (OS) is one of these methods, which with phenomenological and action-oriented view, tries to get better system requirement analysis. In this research, first, organizational semiotics and SSADM was compared, with focus on their ability to elicit and analyze IS user requirements, and then, OS was applied in analyzing an IS requirement analysis case. Research findings show that OS in many dimensions is superior to SSADM although SSADM has superiority in few dimensions too. Therefore using OS can help analyzing IS user requirements more appropriately.
Designing of a Decision Support System (DSS) for resource allocation with genetic algorithm approach (Case Study: Central Library of Tarbiat Modares University)
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: The allocation of information is one of the main responsibilities of a manager. In case there is a limitation in the available resources, the issue of resources allocation is raised. Universities and post graduate centers have faced limitations in accessing resources such as budget, human resources, physical space, etc. This problem results in inappropriate use of the approved budget in buying and sharing the different types of information resources, lack of easy access to information resources by users, and users’ dissatisfaction. This paper is intended to see whether the model of genetic algorithm can be used in helping library heads of university to develop a support system for the proper allocation of resources. The data of the central library of a university as the main core of DSS through using genetic algorithm in MATLAB was used in order to come up with a better distribution of effective resources. Research methodology used in this paper was field study and survey. The findings indicated that genetic algorithm was successful in achieving this end.
Topic maps standard and its application in library and information science
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: Topic maps are an ISO standard (ISO 13250) that is used for presenting the information about information resources structures. The initial idea of this standard was raised in 1991 and due to its strength it turned into an ISO standard. This paper investigates concepts and model of topic maps and aims to mention applications of this standard in library and information science (LIS) realm. A topic map, as a type of document is defined as XML or SGML technically. Research show that this standard is compatible with some of LIS techniques and rules especially in knowledge organization, but it attempts to use these rules in the web. So it can be said that according to some challenges that LIS field faces in adapting traditional techniques for knowledge organization in the Web, topic maps standard can help in solving such problems and challenges and this is what some experts of LIS tried to do.

Identifying and Analyzing Help Facilities and Capabilities in Iranian Digital Libraries Software
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: Purpose: The purpose of this research lies in identifying and analyzing help facilities and capabilities in Iranian digital libraries software based on representation, content, format, style and access criteria. Method: The method of this research is based on descriptive survey. 13 Iranian digital libraries were selected as a sample. The tool for collecting the data was a checklist made by a researcher. Results: The mean of the overall state of the help facilities and capabilities scores (33 from 100) is an indication of the suboptimal state of these facilities and capabilities. This implies that the designers and programmers of these digital libraries have been rather negligent when it comes to effectively designing help facilities and capabilities. This lack of attention can lead to inefficiencies and lack of user interest towards digital libraries. Findings show that from a representational aspect, only National Library and Archive digital library have a score higher than 50%. Furthermore, from a content-based point of view, only four digital libraries (Tebyan, Islamic Document and Information Center, Human Sciences and National Library and Archive) have a score higher than 50%.

Analysis of Azari Language based on Parsing using Link Gram
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)

description: There are different classes of theories for the natural lanuguage syntactic parsing problem and for creating the related grammars .This paper presents a syntactic grammar developed in the link grammar formalism for Turkish which is an agglutinative language. In the link grammar formalism, the words of a sentence are linked with each other depending on their syntactic roles. Turkish has complex derivational and inflectional morphology, and derivational and inflection morphemes play important syntactic roles in the sentences. In order to develop a link grammar for Turkish, the lexical parts in the morphological representations of Turkish words are removed, and the links are created depending on the part of speech tags and inflectional morphemes in words. Furthermore, a derived word is separated at the derivational boundaries in order to treat each derivation morpheme as a special distinct word, and allow it to be linked with the rest of the sentence. The derivational morphemes of a word are also linked with each other with special links to indicate that they are parts of the same word. Finally the adapted unique link grammar formalism for Turkish provides flexibility for the linkage construction, and similar methods can be used for other languages with complex morphology. Finally, using the Delphi programming language, the link grammar related to the Azeri language was developed and implemented and then by selecting 250 random sentences, this grammar is evaluated and then tested. For 84.31% of the sentences, the result set of the parser contains the correct parse.

description: Asteroseismology may in principle be used to detect unresolved stellar binary systems comprised of solar-type stars and/or red giants. This novel method relies on the detection of the presence of two solar-like oscillation spectra in the frequency spectrum of a single lightcurve. Here, we make predictions of the numbers of systems that may be detectable in data already collected by the NASA Kepler Mission. Our predictions, which are based upon TRILEGAL and BiSEPS simulations of the Kepler field of view, indicate that as many as 200 or more ``asteroseismic binaries'' may be detectable in this manner. Most of these binaries should be comprised of two He-core-burning red giants. Owing largely to the limited numbers of targets with the requisite short-cadence Kepler data, we expect only a small number of detected binaries containing solar-type stars. The predicted yield of detections is sensitive to the assumed initial mass ratio distribution of the binary components and therefore represents a sensitive calibration of the much debated initial mass ratio distribution near mass ratio unity.

Meta-analysis: An Approach to Synthesizing and Evaluating Research on Knowledge and Information Science
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: Introduction and Objective: Enquiry through research for achieving more confirmed results, removing existing discrepancies among various studies, and discovering knowledge gap are of main concerns in scientific research. As a systematic approach, meta-analysis tends to orientate this goal by statistical synthesis of quantitative results obtained from independent studies relating to a research problem. This article aimed to set forth an introductory context for conducting meta-analysis in various research problems of knowledge and information science (KIS). Method: This paper used an analytical review to describe the history, methods, statistical approaches, and challenges and opportunities of meta-analysis in KIS. As a systematic review, meta-analysis has some ordered and written stages directed by a protocol. Findings: Statistical summarization of the findings of included studies is the main stage which has three approaches. Despite its importance in developing a scientific field, meta-analysis has not been widely known and conducted in the KIS field and there are some discrepancies in its conduct. The authors of original research articles and journal editors should consider some guidelines for authoringpapers in such a way that they can be easily included in meta- analysis. Originality/ value: This study is a step for introducing the principles and references of meta-analysis to KIS scientific communication as a new and necessary approach to synthesize and evaluate the increasing studies in the field, especially those conducted in Iran.
The Effect of User’s Personality Characteristics on Relevance Judgment
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: The aim of research is to investigate the influence of user’s characteristics on their relevance judgment. The research method was an analytical survey in which 40 masters students and graduates of Information and Knowledge Sciences formed the research population. NEO-personality inventory-revised was used to investigate the population in 5 factors (Extraversion/ Neuroticism/ Openness to experience/ agreeableness/ Conscientiousness). Relevance judgment was perfomed on 10 first retrieved records in Google for 5 keywords that had been searched by the research population and precision was measured. Findings showed that users’ relevance judgment is not the same despite the intervening control Extraversion and agreeableness have positive and significant relationship with relevance judgment and there is not any significant relationship between Neuroticism, Openness to experience and Conscientiousness with relevance judgment. In other words, users with characteristics such as Extraversion and agreeableness retrieved more related records. In general, some personal characteristics have influence on relevance judgment. Library and information managers can improve search process through providing suitable job conditions and suitable environment for users to search information in better situations.
An Investigation into Students' Perception of Electronic Services in Academic Libraries: Based on Azjen`s Theory of Planned Behavi
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: The effect of information technology on providing services in academic libraries is a metter of high significance. New technologies not only affect the forms and delivery of library services but also affect users' behavior and perception. This study is a descriptive research considering post-graduate students in Ferdowsi university of Mashhad. This paper examines the behavior and perception of E-service users in university libraries based on Adjen`s theory of planned behavior. By using stratified random sampling, 493 questionnaires were distributed and path analysis was used to analyze the collected data. The results of path analysis showed that intention and normative beliefs directly affect the behavior of library clients. In the final model compared with Adjen’s earlier model, attitude plays an important role through intention and thus indirectly influences behavior of electronic services users in libraries.
A Survey on Density and Size of Co-authorship Networks in Information Science Journals
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: Scientific collaboration has always been of interest to researchers. The analyses of data relating to scientific collaboration is one of the techniques by which we can evaluate research activities. Co-authorship network analysis can represent good information regarding the patterns and structures of co-authorship. Social network analysis was used as the research method. The research population included twenty journals of Information Science which had an impact factor of 0.635 as a minimum from the years 1996 to 2010. The research findings showed that Journal of the American Medical Informatics Association with 0/3 network density has a highest co-authorship network density. Low connection existed in coauthorship network of Information Science journals and co-authorship networks of these journals were loose and sparse. The Results showed that co-authorship networks of information science journals had a low density. Compactness of this journal is low and co-authorship networks had a low cohesion. Results of this research also showed that the density of co-authorship networks of Information Science is lower than Medical Sciences and higher than Management and Social Computations.

description: Considering the issue of estimating small probabilities p, ie. measuring a rare domain F = {x | g(x) > q} with respect to the distribution of a random vector X, Multilevel Splitting strategies (also called Subset Simulation) aim at writing F as an intersection of less rare events (nested subsets) such that their measures are conditionally easily computable. However the definition of an appropriate sequence of nested subsets remains an open issue. We introduce here a new approach to Multilevel Splitting methods in terms of a move of particles in the input space. This allows us to derive two main results: (1) the number of samples required to get a realisation of X in F is drastically reduced, following a Poisson law with parameter log 1/p (to be compared with 1/p for naive Monte-Carlo); and (2) we get a parallel optimal Multilevel Splitting algorithm where there is indeed no subset to define any more. We also apply result (1) in quantile estimation producing a new parallel algorithm and derive a new strategy for the construction of first Design Of Experiments in meta-model based algorithms.
