BILATERAL SOCIAL DIALOGUE IN THE EDUCATION SECTOR IN LATVIA DURING THE COVID-19 PANDEMIC

2021

In 2020, the world was unprepared for the spread of the coronavirus pandemic. , . In Latvia, respective decisions and restrictions were made at the national, municipal and educational institution’s level, as it was important to respond promptly, flexibly and in accordance with the individual’s health security to ensure safe educational process. During the Covid-19 pandemic, distance learning was provided at most educational institutions, which was not a common practice until now. It facilitated the digitalisation of education, led to rapid adaptation to change and learning to work in times of crisis and limited resources. In the paper, theoretical findings of human capital and the agent net…

Flexural properties of the epoxy resin filled with single and hybrid carbon nanofillers

2020

Abstract The aim of this paper was to estimate the effect of moisture and temperature on the flexural properties of the epoxy filled with single and hybrid carbon nanofillers (CNTs and CNFs) and to reveal the most environmentally stable NC. Water absorption at 70 °C until equilibrium moisture content and heating at 70 °C for 4 weeks were followed by freezing at -20 °C for 8 weeks. Microstructural characterization of optical images revealed homogeneous dispersion of all carbon nanofillers in the epoxy resin at microscale. Positive nanofiller effects were found for sorption, flexural and thermophysical characteristics of the epoxy resin. The most environmentally stable NC was epoxy filled wit…

In search of a theoretical framework of factors influencing work and life balance

2021

Work and life balance (WLB) has gained noticeable attention amid the pandemic. Even before the outbreak of COVID-19, the increasing pace of life encouraged the investigation of individual and organisational aspects of WLB. Physically and mentally healthy people help society develop and grow. Health issues caused by work and life imbalance lead to dissatisfaction with both work and life, which, in turn, leads to higher stress and stress-related illnesses, for instance, burnout. From the organisational point of view, WLB is a factor in analysing the efficiency of an enterprise. The consequences of a work-life imbalance are intentional or unintentional absence, high employee turnover, low prod…

Diversity of human capital attributes and diversity of remunerations

2007

07053 - 16 pages; The purpose is to provide some empirical evidence for promoting new insights into the economics of education. Particular attention is paid to the concept of competence and its influence on employee reward. The paper aims at comparing the impact on fixed earnings and flexible pay of the traditional human capital theory variables (education and experience) on the one hand and of specifically identified and assessed competences, on the other hand. The objective is to test if the HCV (years of schooling, years of labour market experience) and competences substitute or complement each other in the definition of earnings.

Auditory Phenomena and Human Life: Phenomenological Experience

2018

The present study analyzes auditory phenomena from the point of view of hermeneutical phenomenology and shows their interconnectedness with the understanding of man, hearing and listening within the context of human life as the horizon of meaningful sonority and silence. The central questions to be answered in this study are these: What is experienced as sound and sonority? How does a human see himself in inclusion of his being from where he listens, understands, and speaks? The study explores the classical standpoints of Husserl’s phenomenology and other philosophical apprehensions which confirm that auditory phenomena is not to be apprehended solely as an isolated horizon but as being per…

Force/Torque-Sensorless Joint Stiffness Estimation in Articulated Soft Robots

2022

Currently, the access to the knowledge of stiffness values is typically constrained to a-priori identified models or datasheet information, which either do not usually take into ac- count the full range of possible stiffness values or need extensive experiments. This work tackles the challenge of stiffness estimation in articulated soft manipulators, and it proposes an innovative solution adding value to the previous research by removing the necessity for force/torque sensors and generalizing to multi-degree- of-freedom robots. Built upon the theory of unknown input-state observers and recursive least-square algorithms, the solution is independent of the actuator model parameters and its in…

Robust and Decoupled Position and Stiffness Control for Electrically-Driven Articulated Soft Robots

2022

The control of articulated soft robots, i.e. robots with flexible joints and rigid links, presents a challenge due to their in- trinsic elastic elements and nonlinear force-deflection dependency. This letter first proposes a discrete-time delayed unknown input- state observer based on a nominal robot model that reconstructs the total torque disturbance vector, resulting from the imperfect knowledge of the elastic torque characteristic, external torques, and other model uncertainties. Then, it introduces a robust controller, that actively compensates for the estimated uncertainty and allows bounded stability for the tracking of independent link position and joint stiffness reference signals.…

Managing in-country transportation risks in humanitarian supply chains by logistics service providers: Insights from the 2015 Nepal earthquake

2017

International audience; Humanitarian supply chains (HSCs) play a central role in effective and efficient disaster relief operations. Transportation has a critical share in HSCs and managing its risks helps to avoid further disruptions in relief operations. However, there is no common approach to or culture of risk management that its applicability has been studied through recent cases. This paper incorporates an empirical research design and makes a threefold contribution: first, it identifies in-country transportation risks during Nepal response. Second, we evaluate afore identified risks through an expert driven risk assessment grid. Third, we use our field data to study how some humanita…

Mechanical characterization of bio-based composite/metal laminates for an application in street furniture

2019

In this work, it is proposed to study the influence of three manufacturing parameters in the development of bio-basedcomposite/steel hybrids. These parameters arethe methodof assembly between composite and metal, the distribution of composite and steellayers throughthe thicknessof the hybrid,and the stacking sequence of the composite part of the hybrid. The study was conducted through impact tests at different energies and quasi-static three-point bending tests. For each of these parameters, the influenceon the mechanical properties of the hybrid is evaluated.The results show that these properties depend essentially on the relative distribution of steel and composite through the thickness.
