El impacto de la regulación en el comportamiento medioambiental: un análisis sobre los países europeos
Get PDFThis study provides new evidence on factors driving firms’ eco-innovation in
the European Union based on data from the Community Innovation Survey for
the years 2008 and 2014 for eleven European countries. Firstly, our findings
reveal that the propensity to eco-innovate changes over time. Secondly, the
propensity to eco-innovate is unequally distributed across sectors, given that
it is concentrated in a few sectors. Thirdly, we find that sectoral behavior
is strongly influenced by the taxonomy of green sectors introduced by the
European Union, since the propensity to innovate is higher in the carbon
leakage taxonomy than in the mitigation and adaptation taxonomy. These
results provide further insights into the sectoral factors driving eco-innovation
diffusion. Moreover, these findings are relevant to increase environmental
stringency, as they contribute to the diffusion of eco-innovation across sectors,
especially in those that do not innovate.En este estudio se han obtenido nuevas evidencias acerca de las empresas ecoinnovadoras en la Unión Europea, a partir de los datos de la encuesta de innovación comunitaria para los años 2008 y 2014 en once países europeos. En primer lugar, se ha observado que la propensión a ecoinnovar cambia con el tiempo. En segundo lugar, se ha verificado que la dicha propensión no se distribuye de forma simétrica en todos los sectores, de forma que se concentra en unos pocos. En tercer lugar, se ha constatado que el comportamiento sectorial depende en gran medida de la taxonomía de sectores verdes introducida por la Unión Europea, ya que la propensión media a innovar aumenta en la taxonomía de fuga de carbono con respecto a la de mitigación y adaptación. Estos resultados permiten profundizar en las características sectoriales que presenta la difusión de las ecoinnovaciones. Además, son relevantes para regulación medioambiental, ya que ayudan a difundir las ecoinnovaciones en todos los sectores, con especial atención en aquellos que no realizan actividades de innovadoras
Psychological distress among unemployed migrants settling in southwestern Spain A cross-sectional study
Get PDFMigrants living in the informal settlements of Southern Spain tend to have precarious employment and poor living
conditions, making then vulnerable to mental health issues. This study aimed to assess psychological distress in a
sample of unemployed migrants residing in informal settlements in the province of Huelva (southern Spain), during the
fourth wave of the COVID-19 pandemic. A descriptive cross-sectional study was conducted during the months of April
to June 2021, through a heteroadministered questionnaire, in informal settlements. The measurement instrument was the
General Health Questionnaire (GHQ-12), used to analyze psychological distress, and other sociodemographic and healthrelated
variables. Univariate and bivariate descriptive data analysis were performed, using the nonparametric statistics
Mann–Whitney U test, Kruskal–Wallis H test, and Tau β correlation. A categorical regression analysis was performed to
study the relationship between psychological distress and the rest of the variables. The sample consisted of 317 subjects,
83.9% of whom were males, and the mean age was 33.4 years (SD = 10.7 years). The mean score obtained in the
GHQ-12 questionnaire was 13.69 points (SD = 3.86). Significant differences were found between levels of psychological
distress and substance abuse (H = 14.085; P = .049), people who wished to stay in Spain (t = 6987; P = .049), people
who experienced isolation due to COVID-19 contact (t = 1379.5; P = .001), people who needed medical assistance due
to COVID-19 (t = 7.990; P = .018), and those who reported having chronic illnesses (t = 2686.5, P = .02). The mean
score of psychological distress indicates general high levels of psychological distress. Participants who had experienced
isolation due to COVID-19 contact, who consumed substances, and who had chronic illnesses reported the highest levels
of psychological distress.Departamento de Biología Ambiental y Salud Públic

Acerca de la tan célebre y criticada ley española del “Solo sí es sí”. Principales aspectos procesales
Get PDFEn nuestro trabajo, nos centraremos en examinar lo relativo a las modificaciones que, desde una óptica procesal y sobre distintos textos normativos, ha implicado la tan célebre y criticada Ley Orgánica 10/2022 (apodada como Ley del “Solo sí es sí”). En particular, aludiremos a los cambios, implementados en la Ley de Enjuiciamiento Criminal, aprobada por Real Decreto de 14 de septiembre de 1882;1 la Ley Orgánica 5/2000, de 12 de enero, reguladora de la responsabilidad penal de menores; la Ley 4/2015, de 27 de abril, del Estatuto de la Víctima del Delito o la Ley 1/2004, de 28 de diciembre, de medidas de Protección Integral contra la Violencia de Género. Y en lo que respecta a las modificaciones operadas por el citado texto legal sobre la Ley Orgánica 10/1995, de 23 de noviembre, del Código Penal, trataremos lo atinente a los requisitos de perseguibilidad de los delitos de violencia sexual. Asimismo, concentraremos nuestra atención en las actuaciones (con singularidad, las exploraciones de las víctimas y obtención de muestras biológicas) para acreditar el delito, habida cuenta de la relevancia y virtualidad de la prueba en el marco del proceso penal, lo que pone de relieve la necesidad de promover la efectiva especialización en violencia sexual de las unidades de valoración forense integral que asisten a los juzgados de Violencia sobre la mujer, así como la especialización del personal médico forense.
Finalmente, desde una perspectiva crítico-analítica, examinaremos la prohibición de acudir a mediación (y conciliación) en supuestos de violencia de género y violencia sexua
Relationship between Depressive Symptoms, Caregiver Strain, and Social Support with Dementia Grief in Family Caregivers
Get PDFBackground and Objectives: Dementia grief in family caregivers of people with dementia
refers to grieving prior to the death of the care recipient. It is related to psychosocial risk factors that
may have a negative impact on the health of these family caregivers. This study aimed to describe
the relationship between depressive symptoms, caregiver strain, and social support with dementia
grief in family caregivers of people with dementia. Materials and Methods: A descriptive correlational
cross-sectional study was conducted. A total of 250 family caregivers of people with dementia
participated. Dementia grief was the main variable, and depressive symptoms, caregiver strain, and
social support were assessed. Additionally, socio-demographic data were collected. Descriptive
statistics were calculated, and a bivariate correlation analysis and a multiple linear regression analysis
were performed for dementia grief. Results: Higher scores for dementia grief were found in women,
in family caregivers of patients at advanced stages of dementia, and in family caregivers with a low
level of education. High levels of depressive symptoms and caregiver strain and low levels of social
support indicated greater intensity of dementia grief. Depressive symptomatology was the variable
with the greatest influence on dementia grief. Caregiver strain and social support also related
to dementia grief, but to a lesser extent. Conclusions: In family caregivers, depressive symptoms,
caregiver strain, and social support are related to the intensity of dementia grief, with a greater
influence of depressive symptoms. Moreover, being female, having a low level of education, and
caring for a care recipient at an advanced stage of dementia are factors associated with increased
dementia grief. Concerning study limitations, the sample was restricted, belonging to a specific
region of Spain and to a Provincial Federation of associations. It is necessary to exercise caution in
generalizing results due to the sociodemographic and geographical characteristics of the sample.The Spanish Ministry of Universities supported the first author of this research through the University Teacher Training Programme, with reference number FPU19/04001.Enfermerí
Risk perception of healthcare workers in the first wave of the COVID-19 pandemic in Brazil
Get PDFObjectives: To validate the items of the Emotional Impact Questionnaire coronavirus disease-2019
(COVID-19) related to risk perception, estimating its degree, among healthcare workers in the
first wave of COVID-19 pandemic, identifying possible associated factors.
Methods: cross-sectional study in 1872 healthcare workers of Brazil. The population was characterized
by sociodemographic and occupational information, knowledge about COVID-19,
quality of information received, risk perception and preventive measures about the disease,
and sense of coherence.
Results: Being divorced, having a chronic disease, spending more than 1 h per day getting
informed about COVID-19, and always or almost always wearing a mask regardless of symptoms,
as well as self-perception of health were associated with high-risk perception. An inverse association
was found between risk perception, sense of coherence and not knowing if one has had
occasional contact with confirmed COVID-19 cases.
Conclusion: Risk perception is influenced by emotions, experiences, and knowledge. Sense of
coherence and resilience have a role in reducing risk perception. Understanding risk perception is
crucial for developing effective strategies to mitigate the impact of the COVID-19 pandemic and
other similar scenarios.Departamento de Biología Ambiental y Salud Públic
Induction of Oxidative Stress by Waterborne Copper and Arsenic in Larvae of European Seabass (Dicentrarchus labrax L.): A Comparison with Their Effects as Nanoparticles
Get PDFThe aim of this work was to compare the potential induction of oxidative stress and the antioxidant enzymatic response after a short-term waterborne exposure to copper (Cu) and arsenic (As) with that of the nanoparticles (NPs) of these elements (Cu-NPs and As-NPs) in fish larvae of the species Dicentrarchus labrax. Larvae were grouped in several tanks and exposed to different concentrations of contaminants (0 to 10 mg/L) for 24 or 96 h under laboratory conditions. Copper and arsenic concentrations were analysed in larval tissues using ICP-MS. A set of oxidative stress biomarkers, including the levels of hydroperoxides (HPs), and superoxide dismutase (SOD) and catalase (CAT) activities were assessed. The trace element concentrations (mg/kg d.w.) in larvae ranged as follows: 3.28–6.67 (Cu at 24 h) and 2.76–3.42 (Cu at 96 h); 3.03–8.31 (Cu-NPs at 24 h) and 2.50–4.86 (Cu-NPs at 96 h); 1.92–3.45 (As at 24 h) and 2.22–4.71 (As at 96 h); and 2.19–8.56 (As-NPs at 24 h) and 1.75–9.90 (As-NPs at 96 h). In Cu tests, the oxidative damage (ROOH levels) was induced from 0.1 mg/L at both exposure times, while for Cu-NPs, this damage was not observed until 1 mg/L, which was paralleled by concomitant increases in SOD activity. The CAT activity was also increased but at lower metal concentrations (0.01 mg/L and 0.1 mg/L for both chemical forms). No oxidative damage was observed for As or As-NPs after 24 h, but it was observed for As after 96 h of treatment with 0.01 mg/L. A decrease in SOD activity was observed for As after 24 h, but it turned out to be increased after 96 h. However, As-NPs did not alter SOD activity. The CAT activity was stimulated only at 96 h by As and at 24 h by As-NPs. Therefore, the two chemical forms of Cu exhibited a higher bioaccumulation and toxicity potential as compared to those of As. Importantly, the association of both Cu and As in NPs reduced the respective trace metal bioaccumulation, resulting also in a reduction in the toxic effects (mortality and biochemical). Furthermore, the assessment of oxidative stress-related biomarkers in seabass larvae appears to be a useful tool for biomonitoring environmental-occurring trace elements.This work was supported by the “Ministerio de Ciencia e Innovación” (Project CTM2010-17474) and the “Consejería de Economía, Innovación y Ciencia de la Junta de Andalucía” (Project RNM-6641).
