Emociju regulācijas saistība ar uztverto sociālo atbalstu un sasniegumu motivāciju notiesātām personām ieslodzījumā
2019
Šī bakalaura darba mērķis bija noskaidrot, vai pastāv saistība starp emociju regulāciju, uztverto sociālo atbalstu un sasniegumu motivāciju notiesātām personām ieslodzījumā, analizējot teorētisko literatūru, jaunāko zinātnisko pētījumu rezultātus un veicot praktisku pētījumu. Tika izvirzīts pētījuma jautājums: Kādas ir sakarības starp emociju regulācijas, uztverto sociālā atbalsta un sasniegumu motivācijas rādītājiem notiesātām personām ieslodzījumā? Tāpat tika izvirzīti arī sekojoši papildjautājumi: 1) Kādas ir sakarības starp notiesātu personu ieslodzījumā uztvertā sociālā atbalsta rādītājiem, vecumu un attiecību statusu? 2) Kādas ir sakarības starp notiesātu personu ieslodzījumā sasniegu…
Total Pain and Illness Acceptance in Pelvic Cancer Patients: Exploring Self-Efficacy and Stress in a Moderated Mediation Model.
2022
Cancer patients experience pain not only in its physical dimension, but also in a broader context that includes psychological, social, and spiritual aspects due to a higher level of anxiety and stress. The present prospective, longitudinal study examined the relationship between total pain and illness acceptance among pelvic cancer patients, taking into consideration the moderated mediation effects of self-efficacy and stress. The study involved a sample of pelvic cancer patients receiving radiotherapy treatment. Assessments were completed at T1 (before radiotherapy), T2 (after 3–4 weeks), and T3 (after radiotherapy) to assess the psychosocial dynamics of illness acceptance (N = 267). The m…
Estrés percibido y felicidad auténtica a través del nivel de actividad física en jóvenes universitarios
2020
Se ha demostrado en la literatura que el estrés y la felicidad se han relacionado de diversas maneras, y estas a su vez, también se relacionan con la práctica de actividad física (AF). El objetivo de este trabajo fue poner a prueba el papel de la AF en la reducción del estrés y el aumento de la felicidad, así como su rol mediador en la relación entre ambas variables. Concretamente, se pusieron a prueba las siguientes hipótesis: 1) la percepción del estrés (con o sin control de la situación estresante) y la felicidad auténtica difieren en función del nivel de AF; 2) a mayor práctica de AF, mayor percepción de control en la situación estresante y menor percepción de sentirse sobrepasado por l…
Adoption of social media marketing for sustainable business growth of SMEs in emerging economies: The moderating role of leadership support
2021
Social media marketing (SMM) plays an important role in business communication, marketing, operations, and other activities. There is a growing interest among researchers, academicians, and practitioners to understand the role of SMM in business sustainability in small and medium enterprises (SMEs) in an emerging economy, like India. Few studies have attempted to understand this role. Thus, the aim of this study is to examine the impact of adopting social media marketing for sustainable business growth of SMEs in an emerging economy. The study also investigates the moderating role of SME leadership support on the relationship between SMM usage and sustainable business growth of SMEs. After …
Usage activity, perceived usefulness, and satisfaction in a web-based acceptance and commitment therapy program among Finnish ninth-grade adolescents.
2020
Understanding adolescent usage activity and experiences in web-based psychological intervention programs helps in developing universal programs that can be adopted for promotion of adolescent well-being and prevention of mental health problems. This study examined the usage activity, perceived usefulness (i.e., learning of mindfulness, acceptance and value-related skills), and program satisfaction of 157 Finnish ninth-grade adolescents, who participated in a school-based five-week universal acceptance and commitment therapy web intervention called Youth Compass. Individual and growth environment-related antecedents were measured before the five-week intervention, adolescents' usage activity…
The acute effects of massage on muscle tone and perceived recovery
2008
Haakana, Piia 2008. The acute effects of massage on muscle tone and perceived recovery. Department of biology of physical activity, University of Jyväskylä. Bachelor’s thesis. 47 pp. The physiological effects of massage have been controversial in previous studies. There is one previous study on effects of massage on muscle tone but there were no effects during one month intervention. The purpose of this study was to determine the correlations between subcutaneous tissue and rectus femoris muscle thickness and muscle tone. The differences on muscle tone between groups that received massage immediately or one day after the resistance training were examined. The effects of massage on perceived…
A software receiver adaptive phase lock loop method
2009
The aim of this paper is to introduce a new and relatively simple algorithm which is capable to tune the parameters of the loop filter in a phase lock loop, like the one that can be found in a global navigation satellite system receiver. The parameters are chosen while the system is running, in order to make the bandwidth of the filter adaptive with respect to the signal dynamic and strength. A wider bandwidth is obtained to make the filter more reactive when searching the carrier, while the bandwidth gets narrower when the system is in the tracking state, in order to cut off as much noise as possible. The algorithm is based on the observation of the estimated variance of the phase lock loo…
Subjective stress, objective heart rate variability-based stress, and recovery on workdays among overweight and psychologically distressed individual…
2015
Background: The present study aimed to investigate how subjective self-reported stress is associated with objective heart rate variability (HRV)-based stress and recovery on workdays. Another aim was to investigate how physical activity (PA), body composition, and age are associated with subjective stress, objective stress, and recovery. Methods: Working-age participants (n = 221; 185 women, 36 men) in this cross-sectional study were overweight (body mass index, 25.3-40.1 kg/m(2)) and psychologically distressed (>= 3/12 points on the General Health Questionnaire). Objective stress and recovery were based on HRV recordings over 1-3 workdays. Subjective stress was assessed by the Perceived St…
“Coupling interfaces for communication transceivers over power lines”
2010
Model of line to shield power line communication system on a Medium Voltage network
2010
In this paper a complete model of a power line communication (PLC) system on a Medium Voltage (MV) network is presented in the case of a line-ground configuration. A simple and friendly Simulink (R) software is used to develop the model. A distributed parameter MV cable model in line-ground configuration is considered together with the power transformers, the signal coupling networks and the receiving and transmitting line coupling interface of a ST7540 FSK powerline transceiver. The performances of the complete PLC communication system are evaluated for different line lengths by means of the attenuation computed as ratio between the received and transmitted voltage signals.
