description: The thirteenth meeting in a long-standing series of "Time-Resolved Vibrational Spectroscopy" (TRVS) conferences was held May 19th to 25th at the Kardinal Döpfner Haus in Freising, Germany, organized by the two Munich Universities  -  Ludwig-Maximilians-Universität and Technische Universität München. This international conference continues the illustrious tradition of the original in 1982, which took place in Lake Placid, NY.  The series of meetings was initiated by leading, world-renowned experts in the field of ultrafast laser spectroscopy, and is still guided by its founder, Prof. George Atkinson (University of Arizona and Science and Technology Advisor to the Secretary of State). In its current format, the conference contributes to traditional areas of time resolved vibrational spectroscopies including infrared, Raman and related laser methods. It combines them with the most recent developments to gain new information for research and novel technical applications. The scientific program addressed basic science, applied research and advancing novel commercial applications. The thirteenth conference on Time Resolved Vibrational Spectroscopy promoted science in the areas of physics, chemistry and biology with a strong focus on biochemistry and material science. Vibrational spectra are molecule- and bond-specific. Thus, time-resolved vibrational studies provide detailed structural and kinetic information about primary dynamical processes on the picometer length scale. From this perspective, the goal of achieving a complete understanding of complex chemical and physical processes on the molecular level is well pursued by the recent progress in experimental and theoretical vibrational studies.These proceedings collect research papers presented at the TRVS XIII in Freising, Germany
title: Social Norms and Conditional Cooperative Taxpayers

description: This paper incorporates tax morale into the Allingham Sandmo (1972) model of income tax evasion. Tax morale is interpreted as a social norm for tax compliance. The norm strength, depending on the share of evaders in the society, is endogenously derived. Taxpayers act conditionally cooperative, as their evasion decision depends on the other agents' compliance. We characterize an equilibrium which accounts for this interdependence and study the impact of tax and deterrence policies on compliance. Our analysis is then extended to the case of a society which consists of heterogenous communities where individual evasion decisions are embedded in a complex social structure. In this scenario, behavior is crucially influenced by the norm compliance among morale reference groups. Within this framework, we discuss the role of belief management and belief leadership as alternative policy tools.

description: Quadratic penalties can be used to incorporate external knowledge about the association structure among regressors. Unfortunately, they do not enforce single estimated regression coefficients to equal zero. In this paper we propose a new approach to combine quadratic penalization and variable selection within the framework of generalized linear models. The new method is called Forward Boosting and is related to componentwise boosting techniques. We demonstrate in simulation studies and a real-world data example that the new approach competes well with existing alternatives especially when the focus is on interpretable structuring of predictors.

description: This research evaluates the maturity of information technology governance based on the COBIT 5 framework in the National Library and Archives of Iran. The research methodology is based on the COBIT 5 maturity model that measures the capability of IT processes using the ISO / IEC 15504 standard. According to this standard, the capability of each process is evaluated on a scale of 0 to 5 to determine its maturity level. The data were gathered using the COBIT 5 check lists in 5 process areas for 37 IT processes with the help of NLAI managers responsible for each field (based on the COBIT 5 RACI chart). After analyzing the general and specialized indicators of each process, the maturity ranking, maturity level mean and maturity gap were determined in each domain. The results showed that the maturity level achieved in five process areas (1-IT governance processes: Ecaluate, Direct and Monitor; 2-Align, Plan and organize, 3-Build, Acquire and Implement; 4-Deliver, Service and Support; and 5-Monitor, Evaluate and Assess) are not in line with the strategies of the National Library and Archives of Iran, the overall average of maturity level of 37 evaluated processess is 0.81 out of 5, and this organization has a gap of 4.9 to the optimal level.
A search on the scope of IoT definitions to provide a comprehensive definition
Publisher: name: ranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: As a growing issue, there is no formal, universally accepted definition of the Internet of Things. Browsing the literature  in this area, one finds that  that every single researcher and organization has interpreted this technology as they understand it. As a result, 116 various definitions of this emerging technology have been proposed so far. This research  is an attempt to better understand and master the definition of the Internet of Things; the research is carried out through the method of browsing the literature and reviewing the relevant texts. All relevant but varied definitions and descriptions have been exhaustively to provide a definition that could be used as a reference for the stakeholders who want to understand the concept of the Internet of Things. An examination of the definitions provided in this area showed that many of them have  common similarities. In this article, a comprehensive definition of the Internet of Things derived from the scientific definitions available in articles, books, and websites of various global organizations is provided. Finally, the authors provide a fairly comprehensive definition of the Internet of Things that is not an absolute definition of the true meaning of the term in question, but is expected as part of its research and development for a clearer meaning of the term. This study provides a comprehensive overview of the definitions offered in the scope of the Internet of Things and can be useful for those who are new to the Internet of Things or researchers who want to delve deeper into the field.

Year: 2022

description: Given that television is one of the most influential media that uses written language in various TV programs, like advertisements and subtitles, it can be considered as one of the best tools for expanding and teaching the orthography approved by Persian Academy of Language and Literature. In this regard, the present study addresses the representation of Persian orthography in the national media and its compliance with the guidelines approved by the Academy. In this research, an extension of TOPSIS method has been used in the framework of Multiple Attribute Decision Making. To this aim, orthographic content of seven IRIB TV channels namely, One, Two, Three, Four, iFilm, Tamasha and News were analyzed. Then, the compliance rate of each was verified by the “Guidelines on Persian Orthography” approved by the Academy and the channels were ranked by linear assessment method. Findings indicate that none of the seven channels are fully compliant with the guidelines.

description: Der vorliegende Beitrag untersucht die Determinanten der Performance europäischer Arbitrage Collateralized Loan Obligations für das Jahr 2009. Der Fokus liegt dabei auf der Bedeutung der performanceabhängigen Vergütung des CLO-Managers, den Eigenschaften des CLO-Managers und der Transaktionscharakteristika als mögliche Einflussfaktoren der Rating Performance. Es wird gezeigt, dass Transaktionen, bei denen dem CLO-Manager eine Incentive Management Fee gewährt wird, mit einer höheren Wahrscheinlichkeit herabgestuft werden als Transaktionen ohne Incentive Fee. Dieser Befund bestätigt die Hypothese, dass durch die Incentive Fee Risikoanreize für CLO-Manager geschaffen werden. Des Weiteren wird ein positiver Zusammenhang zwischen der Erfahrung bzw. der Größe eines CLO-Managers und der Rating Performance festgestellt. Der Einfluss des Managers auf die Performance einer CLO-Transaktion wird auch an den weiteren in der Studie herangezogenen managerspezifischen Charakteristika wie Typ und Unternehmenssitz bestätigt. Für die Transaktionscharakteristika wird hingegen im betrachteten Untersuchungszeitraum kein signifikanter Einfluss auf die Rating Performance nachgewiesen.

Identifying the Capabilities of Expert Systems and Chatbots in Libraries: A Systematic Review
Publisher: name: ranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: Aim: The number of libraries utilizing smart computers and software to provide different services is unprecedentedly increasing worldwide. Librarians and informants have also attempted to use AI technologies such as expert systems, chatbots, and other smart services to improve and upgrade the quality and quantity of services. Therefore, the present study focused on identifying and introducing the capabilities and applications of expert systems and chatbots for library services.\nMethodology: This study has been conducted in a systematic review method with a seven-step process by Wright et al. These steps in the systematic method are: determining the research question and then the protocol or contract for performing the task, searching for texts, extracting data, evaluating quality, analyzing data and presenting the results, and finally, interpreting the results. Then keywords in this field were searched in international (i.e., Web of Science, Scopus, and Google Scholar) and domestic (i.e., Magiran, Scientific Information Database/SID, and CIVILICA) databases regardless of the time interval. Finally, 34 articles were selected.\nResults: The review of 34 related studies revealed that expert systems are used as technical, general, and managerial services in libraries. However, due to the nature of chatbots that are used for smart conversations and communications as human interactions, various studies have so far identified and introduced the applications of these chatbots only in the general services section of libraries while in reference services and interviews in particular.\nConclusions: Eventually, librarians are expected to become familiar with the capabilities and applications of expert systems and chatbots, as well as participating in the design and application phase of expert systems for libraries. It is further suggested that further studies investigate the role and application of chatbots in the technical and managerial services of libraries to provide a basis for designing these intelligent systems for all library services.

Year: 2022

description: Organizations produce massive volumes of variant and valuable data on a daily basis. Identifying the risks of using and processing organizational big data and finding solutions to manage and reduce these risks, paves the way for organizations to succeed and gain a competitive advantage. On the other hand, in organizations, due to the dynamics of the business environment, the factors affecting the reduction of risks affect each other, and a change in the status of one factor will directly or indirectly affect other factors. For this purpose, by reviewing the thematic literature and the opinions of experts, a framework consisting of four influential areas and 44 effective factors was formed. According to the qualitative nature of the influencing factors, fuzzy concepts have been used for modeling and analysis. Furthermore, to model the relationships between factors and determine the most effective and influential factor in organizations, the FUZZY DEMATEL technique has been used. In this article, the modelling is based on the opinion of experts and subsequently, the results of modeling and calculations have been evaluated with the opinion of experts. By using the achievements and modelling methods mentioned in this research and according to the needs of the organization, they can model and plan to minimize the risks of using their organizational big data as much as possible.

Application of the Neural Network-based Machine Learning Method to Classify Scientific Articles
Publisher: name: ranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: Since 2001s (1380s according to the Iran’s solar calendar), the increasing rate of writing and publishing scientific articles in Iran has become very intense. This caused in addition to the governmental organizations, such as Irandoc & the National Library and Archives of the Islamic Republic of Iran, numerous other online systems, such as the General Portal of Humanities, Noormags, Magiran, Elmnet, Civilica, etc, to manage knowledge and to provide structured archives of the scientific documents. Each of these archives provides facilities to the user. One of these facilities is searching on the documents. An accurate search can greatly improve the usage of these online systems. To increase the accuracy of the search result, it is necessary to determine the scientific field of articles. Classifying large volumes of scientific resources in different fields is very time-consuming. Using machinery methods can be a solution to reduce the severity of the task.\nThe main contribution of this paper is to provide a classification model to classify Persian scientific articles. Although in previous studies, the classification task has been mainly used for simple texts, in this study, the neural network-based classification models, such as convolutional and perceptron neural networks, are used with the contextualized semantic representation, such as ParsBERT; and the results are compared with the other common method utilized for vectorization, namely Word2Vec. To this end, we use the data from the General Portal of Humanities, which includes various articles in the Humanities and each article contains the label of the field. One of the neural network characteristics is that a set of hidden features from the data in the vector space is created and used to train the model. According to the experimental results, the Perceptron classifier that utilized ParsBERT representation obtained the highest performance which is 74.71% based on the Micro F-score, and 72.55% based on the Macro F-score.
A Persian Citation Parsing Method Using Support Vector Machine
Publisher: name: ranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: Human users can easily divide a bibliographic reference to its constructing fields such as authors, title, journal, year, etc. However, due to the variations in formats and errors made by the authors in citing documents, it is difficult to automate this task. There exist many solutions for this problem, known as citation parsing problem in the literature, however, none of them is compatible with Persian language. This is mainly due to high language-sensitivity of these solutions. Considering the important role of citation parsing in tasks such as autonomous citation indexing and information retrieval, in this paper, we propose an intelligent method for citation parsing in Persian language. The proposed method uses the support vector machine (SVM) classification method as its core. The results of testing the proposed method using a dataset designed for this task show 95% in average for precision, recall and F1 measures for extracting different fields from a bibliographic reference, which is quite plausible.

Year: 2022

description: At present, most of the daily shopping of people is done through systems and online stores; therefore, providing a model for evaluating systems and online stores in order to boost the business market and the competitive environment between systems and online stores will be very important. The main purpose of this study is to provide a model for evaluating these systems. Initially, resources related to the evaluation of online store websites and the models used for them were collected and reviewed; then, using qualitative content analysis, the concepts available in online store websites were extracted and categorized into thematic items; finally, the obtained themes were adapted to the main dimensions of Delon and McLean model. Lavshi content validity method was used to confirm the validity of the evaluation model and Cronbach's alpha coefficient was used for reliability. According to the five main dimensions of Delon and McLean model, the evaluation model of systems and online stores was presented in 44 appropriate items. In terms of system quality, 7 items, information quality, 11 items, service quality, 18 items, user use and satisfaction, 6 items, and personal effects, 2 items were approved. Given that the creation and use of online stores in Iran is still young and online shopping through the website of online stores is constantly expanding, the items obtained in this study in the form of Delon and McLain model are among the key indicators. Are considered necessary to improve service delivery and business prosperity and need to be considered by designers and their stakeholders; Therefore, it is very important to use all the appropriate and accepted items in the model of this research. In general, by reviewing the obtained items, it seems that in addition to ensuring the credibility of the online store to buy from it, it is very important to pay attention to the user interface and customer relationship management system; In addition, many items such as the existence of search tools, proper categorization of goods in order to facilitate customer interaction with the system and the online store indirectly indicate the importance of the user interface.

description: Cap and trade mechanisms enjoy increasing importance in environmental legislation worldwide. The most prominent example is probably given by the European Union Emission Trading System (EU ETS) designed to limit emissions of greenhouse gases, several other countries already have or are planning the introduction of such systems. One of the important aspects of designing cap and trade mechanisms is the possibility of competition authorities to grant emission permits for free. Free allocation of permits which is based on past output or past emissions can lead to inefficient production decisions of firms’ (compare for example BÂ¨ohringer and Lange (2005), Rosendahl (2007), Mackenzie et al. (2008), Harstad and Eskeland (2010)).Current cap and trade systems grant free allocations based on installed production facilities, which lead to a distortion of firms’ investment incentives, however. It is the purpose of the present article to study the impact of a cap and trade mechanism on firms’ investment and production decisions and to analyze the optimal design of emission trading systems in such an environment.
The Impact of Data Lack and Data Sparsity on the Effectiveness of the Results of the RICeST Journal Finder Results: A Case Study in the Field of Engineering

Year: 2022

description: Several factors are involved in the production and presentation of recommender systems.The aim of this study was to investigate the effect of the two challenges lack and sparsity of data on the effectiveness of the proposed results of the RICeST Journal Finder. The corpus includes more than 15,000 articles from technical and engineering publications in the period 2013 to 2017, which have been collected from their website. Textual elements of these articles were extracted, normalized and processed, and a research body database was created. Based on the number of collected articles, by using Cochran's formula, 400 basic articles that previously published in related to the topic of each journal were selected in a random-proportional method. Title and abstract of these articles as a query, in order to receive the system Journals suggested, to print the article in two stages of before and after improving the two challenges of lack and sparsity of data in the test corpus. The suggested results in each step were saved in Excel. Finally, the effectiveness of the system results in each stage was determined by Leave-one-out Cross-Validation method and based on the accuracy criterion in k.The relative abundance of categories showed that, in the current situation, the target journal was suggested in only 26% of searches in the first 3 ranks. After enriching, normalizing and processing the data and thus improving the lack of data challenge, although 30% of the results were still rated above 10; But the accuracy of the results in the first 3 ranks increased by 15%. Also, after thematically categorizing the data with the aim of improving the sparsity challenge, 30% increase in the accuracy of the system results in the first 3 ranks compared to the previous step was achieved. The results of this study showed that enriching the database, improving the processing process and thematic classification of data in RICeST journal finder can reduce the two challengs lack and sparsity of data and increase the effectiveness of the proposed results of this systems.

description: In multi-category response models categories are often ordered. In case of ordinal response models, the usual likelihood approach becomes unstable with ill-conditioned predictor space or when the number of parameters to be estimated is large relative to the sample size. The likelihood estimates do not exist when the number of observations is less than the number of parameters. The same problem arises if constraints on the order of intercept values are not met during the iterative fitting procedure. Proportional odds models are most commonly used for ordinal responses. In this paper penalized likelihood with quadratic penalty is used to address these issues with a special focus on proportional odds models. To avoid large differences between two parameter values corresponding to the consecutive categories of an ordinal predictor, the differences between the parameters of two adjacent categories should be penalized. The considered penalized likelihood function penalizes the parameter estimates or differences between the parameters estimates according to the type of predictors. Mean squared error for parameter estimates, deviance of fitted probabilities and prediction error for ridge regression are compared with usual likelihood estimates in a simulation study and an application.

description: This paper provides the first large scale study that examines the impact of both individual- and group-specific factors on the benefits users obtain from their user communities. By empirically analysing 924 survey responses from individuals in 161 Computer Associates' user groups, this paper aims to identify the determinants of successful user communities. To measure success, the amount of time individual members save through having access to their user networks is used. As firms can significantly profit from successful user communities, this study proposes four key implications of the empirical results for the management of user communities.

description: This paper analyzes the causality between inventor productivity and inventor mobility. The results show that the level of education has no influence on inventor productivity. Making use of external sources of knowledge, on the contrary, has a significant effect on productivity.Finally, firm size has a positive impact on productivity. Firm size also influences inventor mobility, although negatively. Whereas existing research implicitly assumes causality to point in one direction, this study ex-ante allows for a simultaneous relationship. To deal with theexpected endogeneity problem, instrumental variables techniques will be employed. Results show that mobile inventors are more than four times as productive as non-movers. Whereas mobility increases productivity, an increase in productivity decreases the number of moves.

description: Germany is one of few countries in which the monetary compensation for inventors is not only determined by negotiations between employer and employee-inventor, but also byrelatively precise legal provisions. In this paper, we describe the characteristics of the German Employees’ Inventions Act (GEIA) and discuss which incentives it creates. We rely on responses from a recent survey of 3,350 German inventors to test hypotheses regarding this institution. We conclude from our data that the law creates substantial monetary rewards for productive inventors. The qualitative responses from our survey confirm this view, but also point to a number of dysfunctional effects.

description: There has been a wide-spread misconception based on the imprecise wording of Art. 52 of the European Patent Convention (EPC)that the protection of business methods by patents is prohibited in Europe. This paper investigates the legal framework set by patent laws with respect to the patentability of business methods, contrasting the situation in lege in Europe and the situation in the US. It is shown that in praxi business methods have never been excluded from patentability in Europe. In the empirical part of the paper, 1,901 European patent applications relating to business methods are identified and major patent indicators are computed. Further, a case study from the franking device industry which is characterized by strong competitionfor intellectual property rights is conducted. It contains evidence for the strategic use of business method patents leading to opposition rates against granted patents of 44%.

Development of a model for estimating and classifying the educational performance of undergraduate students using a combination of multilayer neural networks (Case study: Qom University)

description: Students’ growth and development have always been considered important by the education system as they are the future assets of their country. Although many students can flourish their talents and creativity, we are faced with a large number of students each year whose talents are squandered leading them to a position far from success. Today, with the more students entering in different academic levels and the variety of study disciplines, the necessity to properly guide students is felt more than ever. For this purpose, educational data mining has received special attention from the educational system’s officials in recent years. So far, various classification methods and techniques in data mining and machine learning have been used to predict student performance. However, these individual classifiers have limitations such as complexity and instability for predicting performance in the education process. To tackle this problem, ensemble classification has been proposed as a new and efficient method. Ensemble classification systems combine the results of several individual classifiers to provide a model with better performance. In this paper, a new Ensemble classification system is presented using multilayer neural networks and SOM clustering in order to estimate and classify the grade point average of undergraduate students. In addition, we used averaging and majority voting as combination methods for aggregating the results of individual classifiers. Evaluation results on real university data show that our proposed ensemble system provides better accuracy and performance compared to prevalent individual classification methods. Also, the proposed ensemble system obviously outperforms other popular ensemble methods in classifying students’ GPA.

description: The "Emotional Competence Inventory" (ECI 2.0) by Goleman and Boyatzis assesses emotional intelligence (EI) in organizational context by means of 72 items in 4 clusters (self-awareness, self- management, social awareness, social skills) which at large consist of 18 competencies. Our study examines the psychometric properties of the first German translation of this instrument in two different surveys (N = 236). If all items are included in reliability analysis the ECI is reliable (Cronbach’s Alpha = .90), whereas the reliability of the four sub dimensions is much smaller (Alpha = .62 - .81). For 43 items the corrected item-total correlation with its own scale is higher than correlations with the other three clusters. Convergent validity was examined by using another EI instrument (Wong & Law, 2002). We found a significant correlation between the two instruments (r = .41). The German version of the ECI seems to be quite useful, although the high reliability is achieved by a large number of items. Possibilities of improvement are discussed.

description: This thesis explores the integration of sequential art in Mobile Assisted Language Learning (MALL) environments to enhance second language acquisition. Utilizing participatory design methods, the study investigates user preferences and perceptions towards integrating sequential art into language learning applications. Through a comprehensive literature review and surveys with English-speaking learners of Korean, insights were gathered to inform the design phase. Low-fidelity wireframes were developed, balancing user expectations with design principles. Findings suggest the potential of sequential art to enhance language learning experiences, offering engaging and effective pedagogical tools within MALL environments. This research contributes to understanding the nuanced intersection of sequential art and language acquisition, offering insights for future educational applications.

description: The soil root zone of the land surface provides plants with water for transpiration andtherefore biomass production and its excess water percolates downwards and ultimatelyrecharges the groundwater aquifers. Within the project GLOWA-Danube regional scaleimpacts of climate change on the water cycle are investigated. Potential changes in the water cycle based on climate scenarios for 2011 to 2060 are simulated with the decision support system DANUBIA that integrates models of natural as well as social sciences. This article presents the results of DANUBIA driven by an ensemble of 12 climates scenarios generated with a stochastic climate simulator regarding the future state of soil moisture and groundwater recharge in the Upper Danube basin.
