Mobilie līdzekļi skolēnu vārdu krājuma paplašināšanai pamatskolas angļu valodas stundās
2018
Viedtālruņu pastāvīgā klātbūtne pamatskolas skolēnu dzīvē un mobilo mācību līdzekļu strauja attīstība ir pamats idejai par to apvienošanu, lai iepazīstinātu skolēnus ar jauniem motivējošiem vārdu krājuma apguves veidiem. Atsevišķa gadījuma pētījums tika veikts Teteles pamatskolā. Kā datu iegūšanas metodes tika izmantotas skolotāju aptaujas, intervijas ar angļu valodas skolotājiem, 57 skolēnu aptaujas (vecumā no 10 līdz 14 gadiem) pirms pētījuma, mobilo līdzekļu praktiskā izmantošana, un pamatskolas vecuma skolēnu aptaujas pēc pētījuma. Izmantojot pētījumā iegūtos datus, Diplomdarba autors sasniedza mērķi izstrādāt vadlīnijas skolotājiem, kuri vēlās izvairīties no jebkādām iespējamām grūtībā…
Four essays on IT users' psychological states and behaviors
2016
This dissertation is intended to study information technology (IT) users’ psychological states and behaviors. It consists of four essays. The first essay examines how people react to social networking services (SNS). In this essay, we attempted to extend the existing model, which includes dedication- and constraint-based mechanisms, by additionally including the obligation-based mechanism underlying SNS-related behavior. The second essay is designed to investigate individuals’ smartphone use. In particular, we focused on the role of smartphone addiction in shaping individuals’ perceptions about their smartphone. The third essay is about online community behavior. Drawing on the model of eng…
Measurement Properties of Smartphone Approaches to Assess Physical Activity in Healthy Young People: Systematic Review
2022
Background Physical inactivity is a preventable risk factor for several chronic diseases and one of the driving forces behind the growing global burden of disease. Recent evidence has shown that interventions using mobile smartphone apps can promote a significant increase in physical activity (PA) levels. However, the accuracy and reliability of using apps is unknown. Objective The aim of our review was to determine the accuracy and reliability of using mobile apps to measure PA levels in young people. We conducted a systematic review guided by PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Methods Studies published from 2007 to 2020 were sourced from 8 databa…
The Effect of Smartphone-Based Cognitive Training on the Functional/Cognitive Markers of Schizophrenia: A One-Year Randomized Study
2020
Background: Cognitive impairment is associated with long-term disability that results in the deterioration of both the social and professional status of individuals with schizophrenia. The impact of antipsychotic therapy on cognitive function is insufficient. Cognitive training is therefore proposed as a tool for cognitive rehabilitation in schizophrenia. In this study we investigated the effect of self-administered cognitive training using a smartphone-based application on the cognitive function of paranoid schizophrenia patients focusing on response time, correct answer rate, incorrect answer rate, and fatigability to check, if these functions can be functional markers of successful cogni…
Estrategias verdes para el análisis de muestras alimentarias y medioambientales
2021
Los retos actuales de la Química Analítica Verde son el desarrollo, y su implementación en el análisis de rutina, de nuevas metodologías “verdes”, que sean más sostenibles con el medio ambiente. Por ello, el objetivo de esta tesis es desarrollar métodos de análisis directos mediante el empleo de la fluorescencia de rayos X en la determinación del perfil mineral y fomentar el uso del Smartphone como una herramienta de análisis complementaria a las técnicas convencionales en la determinación de compuestos de interés en muestras de alimentos y medioambientales. La presente tesis se estructura en 7 capítulos que de acuerdo con su temática pueden clasificarse en dos apartados: 1. Análisis de ali…
A smartphone application of “Family Connections” to increase the use of skills and improve psychological symptoms in relatives of people with borderl…
2022
The literature reveals that borderline personality disorder (BPD) is an important public mental health problem that affects both the patients and their families. Moreover, studies indicate a high prevalence of psychological symptoms and burden in relatives of people with BPD. Therefore, it is necessary to develop useful and accessible interventions specifically addressed to the caregivers. Smartphone interventions with Ecological Momentary Assessment (EMA) and Ecological Momentary Interventions (EMI) offer several potential advantages in this regard. The aims of our study are to test the effectiveness of a combined intervention supported by a smartphone app versus the same intervention supp…
Sfärisk geometri och kartprojektion
2012
Denna pro gradu-avhandling behandlar sfärisk geometri och kartprojektioner. Första kapitelet ger en introduktion till den icke-euklidiska geometrin sfärisk geometri. Avstånd och vinklar på en sfär definieras och det bevisas bl.a att den kortaste vägen mellan två punkter på en sfär alltid är en storcirkelbåge. Harriot-Girards sats som säger att man kan räkna ut en triangels area med hjälp av sfärens radie och triangelns vinklar bevisas med hjälp av månskäror. Med hjälp av denna sats fås också en regel med vars hjälp man kan räkna ut vinkelsumman i en triangel. Fyra trigonometriska formler för rätvinkliga sfäriska trianglar bevisas med hjälp av trigonometriska regler för trianglar i planet. E…
Evaluating Gender Differences in Problematic Smartphone Use
2022
Abstract. The Smartphone Addiction Inventory (SPAI) is widely used to measure problematic smartphone use (PSU). Although the SPAI has been translated and validated in different countries, its measurement invariance across gender has received little research attention. This study aimed to examine whether men and women interpreted the Italian version of the SPAI (SPAI-I) similarly and, consequently, whether the observed gender differences in SPAI scores, which have been shown in previous studies, could be due to true differences, rather than to differences in measurement. Six hundred nineteen Italian young adults ( Mage = 22.02 ± 2.63; 55.7% women) took part in the study and completed the SP…
Physical Weaponization of a Smartphone by a Third Party
2022
In the literature and media, the treatment of the dangers and exposures posed by smartphones has generally focused on information security or privacy concerns. There have also been reports of fires, explosions, electric shocks, or loss of phone functionality due to faulty design or manufacture. This article provides an overview of acute physical and physiological dangers of smartphones that could be induced or triggered by a third party. It proposes a categorical discussion framework to describe and define the dangers in terms of attack vectors, effects on the smartphone, harms, and potential culprits/instigators. Counterfeit smartphones are themselves a significant potential threat in this…
El papel de la autoestima y la soledad en el uso problemático del smartphone: diferencias de género
2021
RESUMEN El presente estudio investigó las relaciones entre la autoestima, la soledad y el uso problemático del smartphone y las diferencias de género. La muestra fue no probabilística y estuvo compuesta por 202 participantes (106 hombres y 96 mujeres), con edades comprendidas entre los 18 y los 58 años, que completaron las siguientes pruebas: Smartphone Addiction Scale, Social and Emotional Loneliness Scale for Adults y Escala de Autoestima de Rosenberg. Se calcularon los estadísticos descriptivos, la prueba U de Mann-Whitney, análisis de correlación bivariados y dos modelos de regresión múltiple jerárquica. Se hallaron diferencias significativas entre hombres y mujeres en el uso problemáti…
