Tunnetyön kuormittavuus terveydenhuoltoalalla : palvelumotivaatio ja transformationaalinen johtajuus puskuroivina voimavaroina

2015

Tämän pro gradu -tutkielman tavoitteena oli kartoittaa tunnetyön kuormittavuutta suomalaisella terveydenhuoltoalalla. Työn vaatimusten ja voimavarojen mallia (JD-R) hyödyntäen tutkimme, kuinka tunnetyön kuormittavuus työn vaatimustekijänä ja transformationaalinen johtajuus sekä palvelumotivaatio työn voimavaratekijöinä ovat yhteydessä työuupumukseen. Tutkimusaineistoon valikoitui 1450 hoitotyöntekijää, joiden tunnetyön kuormittavuutta (mitattuna emotionaalisella dissonanssilla), palvelumotivaatioita, koettua transformationaalista johtajuutta ja työuupumusta (mitattuna uupumusasteisena väsymyksenä) kartoitettiin kyselylomakkeen avulla. Tutkimushypoteeseina oli, että tunnetyön kuormittavuus o…

Safety Evaluation of Turbo-Roundabouts with and without Internal Traffic Separations Considering Autonomous Vehicles Operation

2021

The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been introduced into the traffic mix alongside conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs, compared to roundabouts without such curbs. The paper will then describe the methodological path followed to build VISSIM models of turbo-roundabouts with and without raised curbs in …

Staying connected and feeling less exhausted : The autonomy benefits of after‐hour connectivity

2023

This study investigates the longitudinal relationship between after-hour connectivity, autonomy and exhaustion. In doing so, we seek to illuminate the role of individuals' connectivity to work in relation to their autonomy and well-being. We juxtapose different effective directions of the relationship between connectivity and autonomy to shed light on whether and how connectivity and autonomy are related to employees' well-being. This is important because research has both often problematized after-hour connectivity and suggested that connectivity is an inherent feature of contemporary workplaces that may benefit employees. In this study, we hypothesize that after-hour connectivity increase…

Electrooxidation of diesel fuel in alkaline electrolyte

2016

In recent decades the demand of energy has increased significantly.Providing more and more energy is an essential task of today’s energetic industry. In the last few years, addition to traditional methods of energy production, alternative energy sources have been developing fast.One of these sources is fuel cell, mainly due to their high efficiency. Generally fuel cells are powered by hydrogen. However, problems with the storage of hydrogen are the reason for the search of new fuels for fuel cells. Moreover, fuel cells can provide an additional/emergency electricity source in energy systems using combustion engines. So, it is important using the main fuel for powering the fuel cell. One of …

Evaluation of biogas production and usage potential

2016

The aim of the research is the development of theoretical and methodical bases for determining the feasibility of plant raw materials growing for its further bioconversion into energy resources and tec hnological materials to maximize profit from business activities. Monograph, statistics, modelling and abstract logical methods have been used during the research. Directions of biogas usage have been examined. Biogas yields from different crops have been analyzed. It has been determined that high methane yields can be provided from root crops, grain crops, and several green forage plants. So, forage beet and maize can provide more than 5,500 m3 of biogas per hectare. Attention is paid to the…

Pathways for the amplification of agroecology in African sustainable urban agriculture

2020

A growing awareness that highly intensified agricultural systems have made a substantial worldwide contribution to the worsening of the resilience capacity of natural ecosystems has, over the last twenty years, brought general attention to agroecological management models. This aspect is even more evident in industrial agriculture, which is based on the use of multiple chemical products derived from non-natural synthesis. In more developed countries, a new idea of ecology linked to agricultural production has been increasingly developed and, for this reason, there has been a greater diffusion of differentiated agricultural models taking into consideration the environmental impact of product…

Contrasts in fitness, motor competence and physical activity among children involved in single or multiple sports

2021

Abstract Study aim: While there is wide debate around specialization in one sport, there is a lack of information about fitness levels and motor competence of children participating in single or multiple sports. Material and methods: The study involved 358 fifth-grade children who participated in a set of health-related fitness and motor competence tests over two consecutive years. A subsample of children (n = 109) wore an accelerometer for seven consecutive days. The independent samples t-test and ANCOVA were used to compare differences between single and multi-sport participants in study variables and changes between baseline and follow-up. Results: Multi-sport participants performed bett…
