Simultaneous production of furfural and levulinic acid from pine sawdust via acid-catalysed mechanical depolymerization and microwave irradiation
2019
Abstract In this work pine sawdust was converted into levulinic acid (LA) and furfural. Sawdust was first pre-treated with sulfuric acid-catalysed mechanical depolymerization. The conversion reactions were then performed with microwave heating at 180 °C. To enhance the furfural yield and the efficient separation of furfural and LA, a biphasic water-toluene reaction system was used. The effect of an additional catalyst, AlCl3, on the yield of LA and furfural was also studied. According to the results the pre-treatment method enhanced the yields of LA. In addition, due to the microwave heating the reaction times were short. Additional AlCl3 catalyst enhanced the LA yield, however excellent fu…
Spanish versión of the Short Depression-Happiness Scale (SDHS): A Reliability and Validity study in a simple of Spanish elderly people
2018
The psychometric properties of the Short Depression-Happiness Scale (SDHS) were analyzed in a sample of 216 Spanish elderly people with an average age of 73.89 (SD = 6.49). An exploratory factor analysis and confirmatory factor analysis were developed in order to identify the factorial solution and the best model fit. Just on factor was identified. Regarding reliability and validity, internal consistency index was .757 and the correlation between the Short Depression-Happiness Scale (SDHS) and measures of others construct, General Health Questionnaire (GHQ) and Center for Epidemiological Studies Depression Scale (CESD) (CESD), were significance. The practical implications of the scale and…

Demanda de autonomía en la relación entre los adolescentes y sus padres: normalización del conflicto
2017
In a family setting, disagreements between parents and their teenage children are commonplace. This study seeks to measure a teenager’s degree of independence alongside their level of communication with their parents in order to identify the most relevant factors in this relationship and to understand its signifi cance. The study shows that teenagers exhibit a marked tendency to seek increased independence as they develop, although their parents may measure the speed at which their children mature differently. The variables of age, self-esteem, and sex (of both the children and their parents) reveal that confl ict between teenagers and their parents is a natural step in the maturation proce…
Relationships Between Health Promoting Activities, Life Satisfaction, and Depressive Symptoms in Unemployed Individuals
2021
Abstract. Background: Previous research has documented that unemployed individuals who engage in recreational activities, either alone or with others, experience higher levels of mental health and psychological well-being relative to those who do not engage in recreational activities. Aims: In this study, we examined whether engagement in health promoting activities, alone or with other family members, is associated with reduced levels of depression and enhanced levels of life satisfaction in unemployed individuals. Method: We employed a cross-sectional design in which we measured life satisfaction, depressive symptoms, consumption of healthy meals and engagement in physical activities in …
Parenting Dimensions and Internalizing Difficulties in Italian and U.S. Emerging Adults: The Intervening Role of Autonomy and Relatedness
2015
The present study examined the associations between emerging adults’ perceived parental psychological control and autonomy support, and their autonomy, relatedness and internalizing difficulties in Italy and the U.S. The participants included 494 Italian and 414 U.S. college students, between 18 and 28 years of age (Mean = 21.58, SD = 2.18). Our findings showed that dependency-oriented psychological control had no significant direct associations with autonomy, relatedness or internalizing difficulties. Moreover, the association between parental autonomy support and internalizing problems was fully intervened by autonomy and relatedness, whereas the association between achievement-oriented p…
A virtual reality system for the treatment of stress-related disorders: A preliminary analysis of efficacy compared to a standard cognitive behaviora…
2011
This paper presents preliminary efficacy data in a controlled study of the use of a virtual reality (VR) system for treating stress-related disorders (Post-Traumatic Stress Disorder, or PTSD; Pathological Grief, or PG; and Adjustment Disorders, or AD). ''EMMA's World'' is a VR application in which patients can explore negative experiences to the degree required for their specific therapeutic needs. To accomplish therapeutic goals, a series of virtual elements is customized to be meaningful to the user; the elements contain the fundamental emotional components that the person must confront. Thirty-nine participants diagnosed with PTSD (N=10), PG (N=16), and AD (N=13) were randomly assigned t…
Relations Between Suicidal Ideation, Depression, and Emotional Autonomy from Parents in Adolescence
2010
We examined the relations between depression, emotional autonomy quality-related constructs of separation and detachment, and suicidal ideation, focusing on the unique and common contribution that depression, separation and detachment made to suicidal ideation. We also examined gender differences. 403 adolescents, 196 boys and 207 girls, completed self-report measures of depression, separation and detachment, and suicidal ideation. The data showed a significant relation between depression and suicidal ideation both for boys and girls, and between detachment and suicidal ideation only for boys. Results for boys supported an additive model such that depression and detachment each contributed …
Emotion Eliciting Events in the Workplace: An Intercultural Comparison
2007
Different emotional experiences at the work place are evaluated in respect to their influence on job satisfaction. A sample of 75 Japanese employees and 169 German employees rated their emotional level following daily hassles in the work place that were attributed on the two dimensions: locus of causality and controllability. It was predicted that the same attribution pattern of daily hassles leads to different emotional responses and different levels of job satisfaction between employees with an interdependent and independent cultural background. Results indicate that equal attribution patterns of job related daily hassles lead to different emotional experiences between the two cultural gr…
