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…
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…
Integrating vehicle specific power methodology and microsimulation in estimating emissions on urban roundabouts
2021
In this study pollutant emissions were estimated from VSP modal emission rates and the distribution of time spent in each VSP mode obtained from the speed profiles both gathered in the field and simulated in AIMSUN at a sample of urban roundabouts. The versatility of the micro-simulation model for a calibration aimed at improving accuracy of emissions estimates was tested in order to ensure that second-by-second trajectories experienced in the field by a test vehicle through the sampled roundabouts properly reflected the simulated speed profiles. The first results which the thesis will refer, confirmed the feasibility of the smart approach that integrates the use of field-observed and simul…
A Research Agenda for Evaluating Strength of Internal Preferences and External Influences in Consumer Smartphone Switching
2015
This article proposes a research agenda to study what causes consumers to switch smartphone manufacturer and operating system brands. International consumer survey is planned for data collection and structural equation modeling method will be used to extrapolate whether internal preferences play a larger role than external influences in consumers’ switching behavior. The effects are expected to be moderated by behavioral control, subjective uncertainty and prior switching experience and controlled with a set of constraint variables. As a theoretical contribution, we propose a new theory to evaluate switching primarily through the latent construct of magnitude of switch. Potential practical …
The hyperspectral and smartphone technology in CBRNE countermeasures and defence
2016
Caused by industrial and military use as well as other sources of chemical, biological, radiological, nuclear and high-yield explosive (CBRNE) materials, the global threat of weapons of mass destruction (WMDs) remains in spite of such weapons being internationally prohibited. With these materials, industrial and transportation accidents are likely in all countries and can also be triggered by natural disasters, such as in Fukushima in 2011. In addition, governments cannot fully control the manufacturing and usage of WMDs, as extreme terrorists have access to as well as the knowledge and motivation to use such materials. Due to multiple large-scale risks, the countering of CBRNE threats requ…
