1Effect of follicle-stimulating hormone on sperm quality and pregnancy rate显示文摘Aim: To evaluate the possible links between ultrastructural sperm quality and the clinical pregnancy rate in infertile males treated with FSH before intracytoplasmic sperm injection (ICSI). Methods: Forty-four infertile males with idiopathic oligo-asthenozoospermia were randomly allocated to the treated (n=24) and non-treated (control,n=20) groups. Semen analysis was carried out by light and transmission electron microscopy (TEM) before and 12 weeks after FSH therapy. ICSI was performed in all couples. Results: TEM revealed a significant improvement in sperm quality after FSH treatment, particularly in men with their partners achieving clinical pregnancy. The pregnancy rate was 33% in the treated group and 20% in the control. Conclusion: Results highlight a positive role of FSH therapy in infertile males before ICSI, which was correlated with an increased pregnancy rate in treated couples.We believe that improved sperm ultrastructure after FSH therapy could positively influence the quality and early stage of embryo development, thereby increasing the probability of embryo implantation.B.

2Active suspension in railway vehicles:a literature survey显示文摘Since the concept of active suspensions appeared,its large possible benefits has attracted continuous exploration in the field of railway engineering.With new demands of higher speed,better ride comfort and lower maintenance cost for railway vehicles,active suspensions are very promising technologies.Being the starting point of commercial application of active suspensions in rail vehicles,tilting trains have become a great success in some countries.With increased technical maturity of sensors and actuators,active suspension has unprecedented development opportunities.In this work,the basic concepts are summarized with new theories and solutions that have appeared over the last decade.Experimental studies and the implementation status of different active suspension technologies are described as well.Firstly,tilting trains are briefly described.Thereafter,an indepth study for active secondary and primary suspensions is performed.For both topics,after an introductory section an explanation of possible solutions existing in the literature is given.The implementation status is reported.Active secondary suspensions are categorized into active and semi-active suspensions.Primary suspensions are instead divided between acting on solid-axle wheelsets and independently rotating wheels.Lastly,a brief summary and outlook is presented in terms of benefits,research status and challenges.The potential for active suspensions in railway applications is outlined.Bin Fu Rocco Libero Giossi Rickard Persson Sebastian Stichel Stefano Bruni Roger Goodall 2020Railway Engineering Science2020,28,1:8

8Exploring the Potentialities of Automatic Extraction of University Webometric Information显示文摘Purpose:The main objective of this work is to show the potentialities of recently developed approaches for automatic knowledge extraction directly from the universities’websites.The information automatically extracted can be potentially updated with a frequency higher than once per year,and be safe from manipulations or misinterpretations.Moreover,this approach allows us flexibility in collecting indicators about the efficiency of universities’websites and their effectiveness in disseminating key contents.These new indicators can complement traditional indicators of scientific research(e.g.number of articles and number of citations)and teaching(e.g.number of students and graduates)by introducing further dimensions to allow new insights for“profiling”the analyzed universities.Design/methodology/approach:Webometrics relies on web mining methods and techniques to perform quantitative analyses of the web.This study implements an advanced application of the webometric approach,exploiting all the three categories of web mining:web content mining;web structure mining;web usage mining.The information to compute our indicators has been extracted from the universities’websites by using web scraping and text mining techniques.The scraped information has been stored in a NoSQL DB according to a semistructured form to allow for retrieving information efficiently by text mining techniques.This provides increased flexibility in the design of new indicators,opening the door to new types of analyses.Some data have also been collected by means of batch interrogations of search engines(Bing,www.bing.com)or from a leading provider of Web analytics(SimilarWeb,http://gffzz7594f747c9634dbeh6fknqqkqouvc6op9.ffgz.tsg.suse.edu.cn).The information extracted from the Web has been combined with the University structural information taken from the European Tertiary Education Register(http://gffzzbd18f4732c3f4d63s6fknqqkqouvc6op9.ffgz.tsg.suse.edu.cn/#/home),a database collecting information on Higher Education Institutions(HEIs)at European level.All the above was used to perform a clusterization of 79 Italian universities based on structural and digital indicators.Findings:The main findings of this study concern the evaluation of the potential in digitalization of universities,in particular by presenting techniques for the automatic extraction of information from the web to build indicators of quality and impact of universities’websites.These indicators can complement traditional indicators and can be used to identify groups of universities with common features using clustering techniques working with the above indicators.Research limitations:The results reported in this study refers to Italian universities only,but the approach could be extended to other university systems abroad.Practical implications:The approach proposed in this study and its illustration on Italian universities show the usefulness of recently introduced automatic data extraction and web scraping approaches and its practical relevance for characterizing and profiling the activities of universities on the basis of their websites.The approach could be applied to other university systems.Originality/value:This work applies for the first time to university websites some recently introduced techniques for automatic knowledge extraction based on web scraping,optical character recognition and nontrivial text mining operations(Bruni&Bianchi,2020).Gianpiero Bianchi Renato Bruni Cinzia Daraio Antonio Laureti Palma Giulio Perani Francesco Scalfati 2020Journal of Data and Information Science2020,5,4:2

11A Tailor-made Data Quality Approach for Higher Educational Data显示文摘Purpose: This paper relates the definition of data quality procedures for knowledge organizations such as Higher Education Institutions. The main purpose is to present the flexible approach developed for monitoring the data quality of the European Tertiary Education Register(ETER) database, illustrating its functioning and highlighting the main challenges that still have to be faced in this domain.Design/methodology/approach: The proposed data quality methodology is based on two kinds of checks, one to assess the consistency of cross-sectional data and the other to evaluate the stability of multiannual data. This methodology has an operational and empirical orientation. This means that the proposed checks do not assume any theoretical distribution for the determination of the threshold parameters that identify potential outliers, inconsistencies, and errors in the data. Findings: We show that the proposed cross-sectional checks and multiannual checks are helpful to identify outliers, extreme observations and to detect ontological inconsistencies not described in the available meta-data. For this reason, they may be a useful complement to integrate the processing of the available information.Research limitations: The coverage of the study is limited to European Higher Education Institutions. The cross-sectional and multiannual checks are not yet completely integrated.Practical implications: The consideration of the quality of the available data and information is important to enhance data quality-aware empirical investigations, highlighting problems, and areas where to invest for improving the coverage and interoperability of data in future data collection initiatives.Originality/value: The data-driven quality checks proposed in this paper may be useful as a reference for building and monitoring the data quality of new databases or of existing databases available for other countries or systems characterized by high heterogeneity and complexity of the units of analysis without relying on pre-specified theoretical distributions.Cinzia Daraio Renato Bruni Giuseppe Catalano Alessandro Daraio Giorgio Matteucci Monica Scannapieco Daniel Wagner-Schuster Benedetto Lepori 2020Journal of Data and Information Science2020,5,3:2
