Vertical Industries Requirements Analysis & Targeted KPIs for Advanced 5G Trials

Just before the commercial roll out of European 5G networks, 5G trials in realistic environments have been recently initiated all around Europe, as pat of the Phase 3 projects of 5GPPP H2020 program [1]. The goal is to showcase 5G's capabilities and to convince stakeholders about its value adding business potential. The approach is to offer advanced 5G connectivity to real vertical industries and showcase how it enables them to overcome existing 4G network limitations and other long standing issues. The 5G EVE H2020 5GPPP project [2] offers cutting edge 5G end to end facilities (in 4 countries) to diversified vertical industry experimenters. The objective is to understand the needs of prominent industries across Europe and to offer tailor made 5G experience to each and every one of them. This paper contributes to the understanding of vertical services' needs, by offering a thorough and concise vertical requirements analysis methodology, including an examination of the 4G limitations. It also provides real life values for the targeted KPIs of three vertical sectors namely, Smart Industry (4.0), Smart Cities / Health and Smart Energy, while assisting market roll out by prioritizing their connectivity needs.Comment: EuCNC 201

Secure Distributed Cloud Storage based on the Blockchain Technology and Smart Contracts

Objectives: This paper addresses the problem of secure data storage and sharing over cloud storage infrastructures. A secure, distributed cloud storage structure incorporating the blockchain structure is proposed that supports confidentiality, integrity, and availability. Methods/Analysis: The proposed structure combines two well-known technologies: one of them is the Ethereum Blockchain and its Smart Contracts and the other is the RSA encryption and authentication scheme. The Ethereum Blockchain is used as a data structure, which ensures data availability and integrity while RSA provides sensitive data confidentiality and source authentication. Findings: As a result, users of the proposed structure can trust it and be certain that they can securely exchange information through a publicly accessible and shared cloud storage. The application can be used either through a user interface (UI) or a command-line interface (CLI). Novelty /Improvement:The novelty of this work is that the system that is proposed could be used for secure data storage on the cloud as well as for file sharing and authentication verification. Also, secure data storage and file sharing are already offered by the proposed system. Doi: 10.28991/ESJ-2023-07-02-012 Full Text: PD

Ambidexterity and Unit Performance: Intellectual Capital Antecedents and Cross-Level Moderating Effects of Human Resource Practices

International audienceThis study develops a cross-level model examining the effects of intellectual capital facets (i.e., human, social, and organizational capital) on unit ambidexterity. Further, it proposes that organizational-level high-performance human resource (HPHR) practices significantly shape these effects as well as the unit ambidexterity–unit performance relationship. Hierarchical linear modeling on multisource and lagged data from a sample of 148 business units from 58 US Fortune 500 firms shows that unit human and social capital positively contributes to unit ambidexterity, unit organizational capital has a negative relationship with unit ambidexterity, and organizational HPHR practices amplify the former and mitigate the latter of these unit-level effects. The findings also reveal that the relationship between ambidexterity and unit performance becomes stronger in organizational contexts of heightened HPHR practices. This multilevel approach increases understanding of how units achieve ambidexterity and attain related performance gains

Iterative Robust Semi-Supervised Missing Data Imputation

© 2020 The Author(s). This work is licensed under a Creative Commons Attribution 4.0 License. For more information, see https://creativecommons.org/licenses/by/4.0/.In many real-world applications scientists are often confronted with the problem of incomplete datasets due to several reasons. The direct analysis of datasets with missing values in attributes inevitably results in inaccurate learning models and erroneous results. Facing effectively the challenge of missing values is an essential step of the data mining process. Imputation is often employed to overcome the shortcomings incurred by missing data during the pre-process stage of data analysis. Therefore, a plethora of statistical and machine learning methods have been proposed and employed with a view to imputing the missing values in incomplete data with their potential or actual values. In this context, the main objective of this paper is to put forward an iterative stepwise imputation method based on the semi-supervised learning approach, called IRSSI. Semi-supervised methods have proved to be particularly effective for exploiting incomplete or partially labeled data with regard to the values of the target attribute. The proposed algorithm was experimentally evaluated on real-world benchmark datasets and artificially generated datasets using different high ratios of missing data. The experimental results demonstrate the efficiency of IRSSI algorithm compared to typical imputation methods.Peer reviewedFinal Published versio

How providing mentoring relates to career success and organizational commitment: A study in the general managerial population

Purpose – This study aims to investigate the relationship of mentoring provided with career success and organizational commitment in the general managerial population. Design/methodology/approach – Participants were 194 native British who were employed in a variety of jobs, professions and industries in the United Kingdom. Findings – Mentoring provided was positively associated with objective and subjective career success and with mentoring received. Furthermore, mentoring provided mediated the relationship between mentoring received and both aspects of career success. However, although career-related mentoring provided was positively associated with mentors' career success and affective organizational commitment, socio-emotional mentoring provided was unrelated to mentors' career success and was negatively related to their affective commitment. Research limitations/implications – The study adds to the literature by indicating that, at least in the Anglo-Saxon organizational environment, mentoring provided, and especially its career-related dimension, is associated with positive outcomes across occupational, professional and organizational boundaries, and that mentoring receipt increases the likelihood of mentoring provision later in the career. Practical implications – Encouraging organizational members to provide mentoring for junior colleagues establishes and perpetuates a mentoring cycle, which entails benefits for mentors, protégés and the organization. Originality/value – This is the first study to investigate the relationship of mentoring provision with career success and organizational commitment in the general working population; hence, to yield generalizable conclusions. In addition it informs on the relative contribution of career-related and socio-emotional mentoring provided to mentor's career outcomes

System Architecture For An Interactive Database To Structural Control OfTransport Network Infrastructure: A Case Study Of Railroad Bridge

The purpose of illustrating a system architecture for an interactive database to control the consequences of catastrophic events is pursued by a case study: the creation of an interactive database that allows one to monitor the environmental situation of a particular area of the Val Susa Valley (Province of Torino-Italy). It is designed to study the possibility of using a procedure that could help in risk assessment, by an estimate of the vulnerability of a particular node, of the transport network infrastructure, identified in the railroad bridge site located in Pont-Ventoux. For this purpose the phases of the project can be identified as follows: i) Use of high resolution satellite images; ii) Management of information through the use of the software package ArcMAP; iii) Implementation of a Data-Base Dynamic associated with a computer interfaced to the Web tab (GIS dynamic); iv) Structural analysis of the bridge after simulation of a catastrophic event. This study shows that GIS based real time monitoring system can be effectively used to detect and rapid bridge structural control for risk assessment, damage evaluation and crisis management

International Graduate Students’ Perceptions and Interest in International Careers

This research developed and tested a comprehensive model of the antecedents of international graduate students' interest in an international career. Based largely on Social Cognitive Career Theory (SCCT), the model included elements that pertain to perceptions of external constraints (perceptions of the labor market, family pressure to return), international student experience (adjustment in the foreign country during graduate studies, exposure and immersion to the international context) and individual factors (self-efficacy with respect to working abroad and outcome expectancy). Participants were 139 international graduate students in the UK. Individual factors and perceived constraints were directly related to interest in an international career. The factors that comprised current international student experience were indirectly related to interest via their relationship with self-efficacy, while adjustment moderated the relationship between self-efficacy and interest. Although the hypothesized moderating role of family pressure to return did not materialize, the findings suggest that perceptions of constraints play a more substantial role in the formation of interest than has been assumed by SCCT theory thus far. The findings are discussed with respect to their implications for the literature and for the policies of host country stakeholders

Willie, the baby of Hutchings family when we went to the Valley never was perfectly well. He is undersized & a cripple He learned to do fine carpernter work & carving, inlaying etc. He was keeping a store in Yosemite this summer that belonged to a dealer in fancy woodwork. I went into the store & asked him if he knew me. He answered no. I said I have know you for over 30 years Then said he you must have know me all my life for I\u27m not much over 30 yrs of age - I made him guess a while then had to tell himmy name. His father they say has never done much for him. Cosie I think I told you about in my first letter.
