- Addressing the complex links between psychopathy and childhood maltreatment, emotion regulation, and aggression-a network analysis in adultsPublication . Moreira, Diana; Silva, Candy; Moreira, Patrícia; Pinto, Tiago Miguel; Costa, Raquel; Lamela, Diogo; Jongenelen, Inês; Pasion, RitaChildhood maltreatment is the strongest predictor of psychopathology and personality disorders across the lifespan and is strongly associated with a variety of psychological problems, namely, mood and anxiety disorders, behavioral and personality disorders, substance abuse, aggression, and self-harm. In this study, we aim to provide a comprehensive picture of the interplay between different traits of psychopathy and distinct dimensions of childhood maltreatment, emotion regulation, and aggression. Using a cross-sectional design, we employed correlational network analysis to explore the nomological network of psychopathy and provide a sample-based estimate of the population parameters reflecting the direction, strength, and patterns of relationships between variables. The sample consisted of 846 adults (71% females) who completed questionnaires measuring psychopathy, childhood maltreatment, emotion regulation, and aggression. The results highlight that disinhibition traits of psychopathy are the closest attributes of early experiences of abuse (but not neglect) in childhood and correlate with all dimensions of emotion regulation difficulties, being specifically associated with reactive aggression. Neglect was a unique attribute in the nomological network of meanness, with widespread correlations with emotion regulation difficulties but also an increased ability to engage in goal-directed behavior. Physical abuse was the only dimension of childhood adversity that was found to be intercorrelated with boldness and increased emotional regulation was found in this psychopathic trait. No significant associations were found between boldness, meanness, and aggression once shared variance with disinhibition was controlled. These results are discussed in terms of their implication for research and clinical practice.
- Arabinogalactan proteins: decoding the multifaceted roles in plant reproductionPublication . Silva, Jessy; Moreira, Diana; Ferreira, Maria João; Pereira, Ana Marta; Pereira, Luís Gustavo; Coimbra, SílviaArabinogalactan proteins (AGPs) are highly glycosylated cell wall proteins essential for plant growth and reproduction. AGPs are extensively decorated with arabinogalactan polysaccharides, composed primarily of arabinose and galactose, along with minor sugars such as glucuronic acid, fucose, and rhamnose. Their glycosylation patterns and glycosylphosphatidylinositol anchor enable interactions with receptors, modulating signal transduction pathways critical for reproduction. AGPs also associate with cell wall components like pectin and hemicellulose, impacting cellulose deposition and cell wall integrity. Recent research highlights AGPs’ role as calcium (Ca2+) capacitors, regulating Ca2+ storage and release during crucial reproductive stages. Despite significant progress, their precise molecular mechanisms remain elusive. In this review, we explore the multifaceted roles of AGPs in plant reproduction, shedding light on the recent progress in their involvement in signalling pathways, cell wall interactions, and Ca2+ homeostasis, while highlighting the ongoing research needed to fully understand their mechanisms in reproductive success.
- Atmospheric CO2 capture by algae: Negative carbon dioxide emission pathPublication . Moreira, Diana; Pires, José C. M.Carbon dioxide is one of the most important greenhouse gas, which concentration increase in the atmosphere is associated to climate change and global warming. Besides CO2 capture in large emission point sources, the capture of this pollutant from atmosphere may be required due to significant contribution of diffuse sources. The technologies that remove CO2 from atmosphere (creating a negative balance of CO2) are called negative emission technologies. Bioenergy with Carbon Capture and Storage may play an important role for CO2 mitigation. It represents the combination of bioenergy production and carbon capture and storage, keeping carbon dioxide in geological reservoirs. Algae have a high potential as the source of biomass, as they present high photosynthetic efficiencies and high biomass yields. Their biomass has a wide range of applications, which can improve the economic viability of the process. Thus, this paper aims to assess the atmospheric CO2 capture by algal cultures.
- Beliefs and violent behavior in interpersonal relationships of young adults: a systematic reviewPublication . Araújo, Eduardo; Santos, Anita; Oliveira, Claúdia; Cruz, Olga Souza; Moreira, DianaBeliefs are information-processing structures formed along an individual’s developmental pathway. Beliefs can legitimize involvement in inappropriate or violent behaviors, particularly when they crystallize into cognitive schemas. While beliefs aid individuals in interpreting the surrounding world, overly rigid and inflexible beliefs can constrain the individual’s ability to process available information. This Systematic Review, carried out according to the PRISMA norms and guidelines, aims to understand the most prevalent beliefs regarding relationships among young adults and to examine their associations with violent or deviant behaviors. Articles included in this review were retrieved from the EBSCO, PubMed, and Web of Science databases in July 2022, resulting in a total of 594 studies, which were subsequently screened by two independent reviewers. A total of 51 studies were then selected for full reading, but 36 were excluded based on pre-defined eligibility criteria, leaving a final sample of 18 studies published between 2014 and 2022. The main objectives, country of origin, instruments used, sample composition and age, main results and conclusions were extracted from each study. Findings point toward the presence of related and legitimate beliefs about violence in intimate relationships, domestic violence, sexual violence, acceptance of the rape myth, or consent to engage in sexual activities.
- Bioactive packaging using antioxidant extracts for the prevention of microbial food-spoilagePublication . Moreira, Diana; Gullon, Beatriz; Gullon, Patricia; Gomes, Ana M.; Tavaria, FreniBioactive food packaging is an innovative approach for the prevention of the growth of food-spoilage microorganisms. Four active extracts from agroindustrial subproducts (Eucalyptus wood, almond shells, corn cobs and grape pomace) with demonstrated antioxidant activity have been investigated for bestowing antimicrobial activity to bioactive packaging. To carry out this evaluation, the antioxidant extracts were tested against five food pathogenic bacteria, namely, Escherichia coli, Pseudomonas aeruginosa, Listeria monocytogenes, Staphylococcus aureus and Salmonella spp. The results obtained showed that all the tested extracts inhibited the growth of all five pathogenic bacteria. From the analysis of the minimal bactericidal concentrations (MBCs), the Eucalyptus wood extract was the most active, being necessary only 2% (v/v) to inhibit Pseudomonas aeruginosa, Listeria monocytogenes, and Staphylococcus aureus, whereas almond shells extract were less active requiring 4% (w/v) to inhibit the growth of Escherichia coli and Pseudomonas aeruginosa and the extract from corn cobs was bactericidal against Escherichia coli and Staphylococcus aureus at a concentration of 4% (w/v). After checking their antimicrobial activity, the antioxidant extracts have been incorporated into sodium alginate films and the maintenance of their antimicrobial properties was confirmed. This work showed that the antioxidant extracts from agroindustrial byproducts exhibited antimicrobial activity and were suitable for incorporation into edible films that could be used in bioactive packaging systems.
- Callous and unemotional traits as precursors to the development of female psychopathyPublication . Cardoso, Ana Raquel; Costa, Maria João; Sani, Ana Isabel; Moreira, DianaObjective: Conduct a systematic review concerning the literature that reflects whether the callous and unemotional traits present in childhood and/or adolescence are precursors in the development of female psychopathy in adulthood. Materials and Methods: A systematic review involved consulting three databases—EBSCO, the Web of Science, and PubMed—for peer-reviewed and quantitative studies within the period 2000–2023. Nine articles with quality of three and above were included. Results: The presence of callous and unemotional traits designates a group of youth that show characteristics associated with psychopathy, specifically when predicting a more severe and chronic pattern of antisocial behaviour. Children with high rates of callous and unemotional traits, who show symptoms of attention deficit hyperactivity disorder in combination with severe conduct problems, are most likely to show features associated with psychopathy. The multidimensional psychopathy construct is considered a better predictor of future and stable antisocial behaviour than the callous and unemotional traits alone model. Conclusions: According to the studies selected, the callous and unemotional traits in childhood seem to be precursors of female psychopathy in adulthood, but only because of the way they seem to enhance conduct problems, disruptive behaviour disorders, and, as a possible outcome, delinquency and antisocial traits, which may be precursors of future psychopathy.
- Community intervention programs for sex offenders: a systematic reviewPublication . Barros, Sofia; Oliveira, Cláudia; Araujo, Eduardo; Moreira, Diana; Almeida, Fernando; Santos, AnitaSexual violence is a phenomenon that negatively impacts the victims' physical and psychological health and well-being. Sex offenders tend not to take responsibility for their actions, have difficulties in emotion regulation and impulse control, paraphilias or other disorders, so they are a difficult group to treat. In addition, the available psychological treatment programs tend to have inconsistent and, sometimes, undesirable results. This systematic review aimed to analyse the recidivism rates of sex offenders treated in community settings. According to the PRISMA guidelines, a systematic search in three databases, EBSCOhost, PubMed, and Web of Science, and a manual search was performed. A total of 319 empirical studies using quantitative methodologies were identified, 27 of which were selected for full-text analysis. In the end, 15 studies were included, published between 1996 and 2020. The objectives, intervention approach, instruments used, and the main results and conclusions were extracted from each study. The studies explored different types of sex offenders, such as: violent sex offenders (e.g., rapists), child abusers, and child abusers with pedophilia (and/or other paraphilias). Results showed that most of the programs had a cognitive-behavioral approach (n = 13). Overall, the interventions appear to be effective in reducing recidivism rates, and some of them led to improvements in other outcomes, such as cognitive distortions, accepting responsibility, victim awareness and empathy, emotional regulation, and offense supportive attitudes. Limitations and implications for future studies were discussed.
- Criminal reactions to drug-using offenders: a systematic review of the effect of treatment and/or punishment on reduction of drug use and/or criminal recidivismPublication . Tomaz, Vera; Moreira, Diana; Cruz, Olga SouzaThe association between substance use and crime is very common, but complex. Several countries have found strategies to face drug abuse and criminality that may exist associated to it, seeking to reduce overcrowded prisons and to promote the reductions of criminal recidivism and/or substance use. Through the guidelines of PRISMA, a systematic review was conducted with the aim to explore the different criminal reactions to individuals who use substances and are involved in the criminal justice system, namely the role of treatment and/or punishment in the reduction of crime recidivism and/or drug (ab)use. After gathering the following criteria of inclusion (individuals who use substances and are involved in the criminal justice system, between 18 and 65 years old, regardless of gender; consumers of licit/illicit psychoactive substances; without psychopathology not related with use/abuse of drugs; treatment programs; judicial interventions) the database found 155 articles between 1971 and 2022 from which 110 were selected for analysis (57 are from Academic Search Complete, 28 from PsycInfo, 10 from Academic Search Ultimate, seven from Sociology Source Ultimate, four from Business Source Complete, two from Criminal Justice Abstracts, and two from PsycArticles); additional records were included trough manual search. From these studies, 23 articles were included, as they answered the research question, and therefore, constitute the final sample of this revision. The results indicate treatment as an effective response of the criminal justice system in the reduction of criminal recidivism and/or drug use, addressing the criminogenic effect of reclusion/imprisonment. Therefore, interventions that privilege treatment should be chosen, although there are still gaps in terms of evaluation, monitoring and scientific publications regarding the effectiveness of treatment in this population.
- Determinants of academic achievement from the middle to secondary school education: a systematic reviewPublication . Costa, Ana; Moreira, Diana; Casanova, Joana; Azevedo, Ângela; Gonçalves, Armanda; Oliveira, Íris; Azevedo, Raquel; Dias, Paulo C.Because it is crucial for psychosocial adjustment and lifelong learning, education is the most relevant tool for ensuring inclusion and reducing inequalities. Due to its relationship with positive outcomes, such as life satisfaction, mental health, job performance or SES, academic achievement is a significant phenomenon that impacts students, families, and educational institutions. The present study sought to contribute to the field by reviewing the literature on the determinants that influence the objective achievements of a typical population of middle- to high-school students. Based on the PRISMA statement, a search for related studies was performed in the WoS, EBSCO, and PubMed databases, and 771 studies published between 1930 and 2022 were identified. After screening based on the analysis of abstracts, 35 studies met the selection criteria. The Bronfenbrenner ecological model served as the theoretical rationale for organizing the studies’ findings. The results of this review highlight the following determinants of school achievement: (i) Personal factors—gender, personality traits, cognitive abilities and academic background, motivation and self-constructs, stress and problem-solving strategies, and substance use; (ii) Contextual microsystem factors—(a) Family—parental educational background; parenting practices and interactions; parental involvement and support; (b) School—school location; school conditions, responsiveness, and practices; (c) Peers—peer-group disagreement management. This systematic review updates the existing empirical evidence on this topic and highlights the complexity of the phenomenon of academic achievement.
- Effects of animal-asisted therapy for anxiety reduction in children and adolescents: a systematic reviewPublication . Brandão, Constança; Sampaio, Maria; Sousa-Gomes, Valéria; Fávero, Marisalva; Moreira, DianaBackground: Animal-Assisted Therapy (AAT) is a clinical approach aimed at building valuable human–animal relationships with both preventive and therapeutic goals. It is provided by a healthcare professional and involves animals (meeting certain criteria) as an integral part of the treatment process. This type of therapy has been shown to have multiple benefits in several areas, such as reducing anxiety in a variety of different groups of people. However, few studies have specifically investigated the benefits of AAT in reducing anxiety in children and adolescents. This systematic review aimed to comprehensively assess the evidence regarding the effectiveness of AAT in reducing anxiety among children and adolescents while also identifying research gaps in this field. Methods: Studies focusing on the relationship of these two variables were obtained from multiple databases (EBSCO, PubMed, and Web of Science). Results: AAT has grown and the literature demonstrates several benefits of this approach. However, few studies have demonstrated the benefits of AAT for reducing anxiety in children and adolescents. Conclusions: Most of these few studies show that this type of intervention can help reduce anxiety levels.
