Comparative study between different methods for the efficiency of the production activity in the wood industry
2017
Generally speaking, the quality and cost of goods and in particular of the wood products is a decisive condition in their sales on the market, attracting buyers to satisfy their wishes and requirements. Starting from the general idea, by which it is considered that the manufacturing activity is effective if production is obtained at maximum quality with a low (minimum) cost, or when the revenue from the sale of products exceeds the market expenditure which is necessary to achieve it, this research article aims to study ways to make production more efficient by methods which could also be applied in the wood industry, by presenting a comparative study on production optimization methods in th…
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.

Understanding risky behaviours in nuclear facilities: The impact of role stressors
2018
Abstract Risky behaviours have received little attention in the safety literature in recent years, compared to safety behaviours such as safety compliance or safety participation. However, it is important to focus on risky behaviours and their predictors in order to prevent accidents. The aim of this study is to explore the impact of role stressors (role ambiguity and role overload) on risky behaviours, and the mediating role of dissatisfaction (both job and safety dissatisfaction). The sample consists of 566 employees from two nuclear power plants in Spain. Structural equation modelling is used to determine the effects of role ambiguity and role overload on risky behaviours. Role stressors…
Summary versus argument tasks when working with multiple documents: Which is better for whom?
2010
Abstract This article reports on two experiments where undergraduates read five documents on a scientific topic and afterwards answered comprehension questions and wrote either summaries or argument essays on the topic. In the first experiment, students who were instructed to work with the documents for the purpose of summarizing their contents displayed better comprehension and integration of document contents than did students instructed to construct arguments from the documents. In the second experiment, focusing on whether the effects of task instructions on multiple-documents comprehension and integration could be moderated by students’ prior knowledge, it was found that only students …
PISA y TALIS ¿congruencia o discrepancia?

Critiquing and Joining Intersections of Disaster, Conflict, and Peace Research
2020
AbstractDisaster research, conflict research, and peace research have rich and deep histories, yet they do not always fully intersect or learn from each other, even when they investigate if and how disasters lead to conflict or peace. Scholarship has tended to focus on investigating causal linkages between disaster (including those associated with climate change) and conflict, and disaster diplomacy emerged as a thread of explanatory research that investigates how and why disaster-related activities do and do not influence peace and conflict. However, definitive conclusions on the disaster-conflict-peace nexus have evaded scientific consensus, in part due to conceptual, methodological, and …
Consumer Satisfaction towards Green Products: Empirical Insights from Romania
2021
The current model of linear economy is causing accelerated consumption and an extensive use of natural resources that accentuates the effects of the current global environmental crisis. In this context, green products are becoming a key element in the transition to a sustainable consumption and production model. The main goal of this paper is to identify the factors predicting youth consumer satisfaction towards green products and to analyze the public perception of green brand products in Romania. Considering these goals, a questionnaire was developed and applied to 268 participants. The results show that a positive attitude towards green products and the level of information held by the c…
