Johtajien työn eettinen kuormittavuus ja sen yhteydet työhyvinvointiin
2011
Tutkimuksessa selvitetiin suomalaisten johtajien työn eettistä kuormittavuutta kahden kuvaajan avulla. Ensinnäkin tutkittiin, kuinka usein johtajat kohtaavat työssään eettisesti haastavia tilanteita, joihin liittyy kokemus eettisestä dilemmasta (johtaja ei tiedä, mikä on oikea toimintatapa tai tietää, mutta joutuu syystä tai toisesta toimimaan sääntöjen, normien tai arvojen vastaisesti). Toiseksi selvitetiin, kuinka stressaaviksi johtajat nämä tilanteet kokevat. Tutkimuksessa selvitettiin lisäksi eettisen kuormittavuuden yhteyttä johtajien työhyvinvointiin (työuupumus ja työn imu) sekä eettisten dilemmojen yleisyyttä johtamistyön eri tilanteissa. Kaikkiaan 902 eri alojen johtajaa ympäri Suo…
Meaningful work, pleasure in working, and the moderating effects of deep acting and COVID-19 on nurses' work
2022
This study aims to verify the association between nurses' perception of the meaningfulness of their work and their pleasure in working, and whether this relationship may change based on the level of deep acting performed to cope with emotional regulation demands and the influence of the COVID-19 pandemic on the healthcare work.Nurses from both private and public Italian institutions (N = 239) completed an online questionnaire between June 2021 and January 2022. A moderated moderation model was tested through SPSS Process macro. The design is cross-sectional.The results show that the perception of meaningfulness of work is positively associated with pleasure in working, especially in conditi…
Hierarchical Analysis of Forms of Support for Employees in the Field of Health Protection and Quality of Work during the COVID-19 Pandemic and the De…
2022
Issues of employee support during the COVID-19 pandemic and the post-pandemic period are of an interdisciplinary nature. Moreover, these should be considered from both an epistemological and a practical perspective. The aim of this study was to determine what forms of support for employees in terms of health and quality of work were provided by employers during the pandemic and what forms of support will be expected by employees after it ceases. The research process was carried out in two stages: primary and secondary exploration and quantitative clarification. In the first stage, a systematic review of the literature and a critical analysis of the so-called grey literature was performed. I…
Efficient Power Allocation for Multi-Cell Uplink NOMA Network
2019
Digital technologies are rapidly shaping the modern concepts of urbanization. It is a key element of developing practical smart cities of the future. In fact, they are the catalyst for the increasing networking of all areas of life in a smart city. Recent development in the domain of communication technologies has opened new avenues to realize the concept of smart cities. One of such communication technology is non-orthogonal multiple access (NOMA) for future cellular communications. This article, therefore, focuses on the interference management of uplink cellular NOMA systems. Specifically, we propose a power optimization technique for NOMA to improve the sum-rate in a multi-cell environm…
Collaborative Mobile Clouds: An Energy Efficient Paradigm for Content Sharing
2018
On the way toward enabling efficient content distribution, reducing energy consumption and prolonging battery life of mobile equipment, an emerging paradigm, i.e., mobile cloud, which is based on content distribution, was proposed. As a mobile platform that is oriented toward content distribution, mobile cloud is also foreseen as an energy-efficient solution for future wireless networks. The benefits of using CMC for content distribution or distributed computing from social networking perspectives have been studied earlier. In this article, we first present the concepts of CMC and then discuss the energy-efficiency benefits from the system-level point-of-view as well as open challenges in d…
Coupled Electric and Hydraulic Control of a PRS Turbine in a Real Transport Water Network
2019
Although many devices have recently been proposed for pressure regulation and energy harvesting in water distribution and transport networks, very few applications are still documented in the scientific literature. A new in-line Banki turbine with positive outflow pressure and a mobile regulating flap, named Power Recovery System (PRS), was installed and tested in a real water transport network for the regulation of pressure and flow rate. The PRS turbine was directly connected to a 55 kW asynchronous generator with variable rotational velocity, and coupled to an inverter. The start-up tests showed how automatic adjustment of the flap position and the runner velocity variation are able to c…
Speed detection of battery-free nodes based on RF Wireless Power Transfer
2020
In the Internet of Things (IoT) era, Wireless Sensor Networks (WSNs) are rapidly increasing in terms of relevance and pervasiveness thanks to their notable real-time monitoring performance across several fields, including industrial, domestic, military, biomedical, commercial, environmental, and other sectors. A highly attractive implementation of WSNs is asset tracking with accurate data regarding the location and transportation conditions of goods, equipment, and the like. One highly promising application of WSNs along these lines is the remote speed monitoring of goods, ideally with battery-free sensor nodes that do not require any maintenance. This, however, represents a major challenge…
Classification of Solutions to the Minimum Energy Problem in One Dimensional Sensor Networks
2016
We classify of the minimum energy problem in one dimensional wireless sensor networks for the data transmission cost matrix which is a power function of the distance between transmitter and receiver with any real exponent. We show, how these solutions can be utilized to solve the minimum energy problem for the data transmission cost matrix which is a linear combination of two power functions. We define the minimum energy problem in terms of the sensors signal power, transmission time and capacities of transmission channels. We prove, that for the point-to-point data transmission method utilized by the sensors in the physical layer, when the transmitter adjust the power of its radio signal t…
Deliberate Play and Preparation Jointly Benefit Motor and Cognitive Development: Mediated and Moderated Effects
2016
In light of the interrelation between motor and cognitive development and the predictive value of the former for the latter, the secular decline observed in motor coordination ability as early as preschool urges identification of interventions that may jointly impact motor and cognitive efficiency. The aim of this study was twofold. It (1) explored the outcomes of enriched physical education, centered on deliberate play and cognitively challenging variability of practice, on motor coordination and cognitive processing; (2) examined whether motor coordination outcomes mediate intervention effects on children’s cognition, while controlling for moderation by lifestyle factors as outdoor play h…
