Stop yelling: interparental conflict and adolescents’ self-representations as mediated by their perceived relationships with parents

Adolescents’ perceptions of their relationship with both parents were examined as mediators linking interparental conflict to their self-representations (SR). Portuguese adolescents (N = 214; 58.4% girls), aged 10-16 years old (M = 13.39), attending public elementary and secondary schools, filled out self-report measures. Multi-mediator path analysis models revealed that interparental conflict predicted less favorable SR in most evaluated domains. This association was mediated by adolescents’ perceptions of (a) support in the mother–adolescent relationship, related to instrumental, social, emotional, physical appearance, and intelligence SR; (b) negative interactions in the mother–adolescent relationship, related to instrumental and physical appearance SR; (c) support in the father–adolescent relationship, related to social and physical appearance SR; and (d) negative interactions in the father–adolescent relationship, related to instrumental SR. This study emphasizes the relevance of interparental conflict and adolescents’ perceptions of their relationship with both parents in their SR construction. Practical implications point to promoting constructive conflict and improving parent–adolescent relationships.info:eu-repo/semantics/acceptedVersio

Maltreatment experiences and psychopathology in children and adolescents: the intervening role of domain-specific self-representations moderated by age

Background: Associations between maltreatment experiences and psychopathology symptoms in children and adolescents are well established. However, the role of domain-specific self-representations (SR) in those associations remains unexplored. Objective: This multi-informant study aimed to explore the indirect associations between maltreatment experiences and children's and adolescents’ psychopathology symptoms (i.e., internalizing and externalizing problems), through domain-specific self-representations, and the moderating role of age in those indirect associations. Participants and setting: Participants were 203 children/adolescents (52.7 % boys), aged 8–16 years old (M = 12.64; SD = 2.47), referred to child/youth protection commissions, their parents, and case workers. Method: Case workers reported on child/adolescent maltreatment, children/adolescents reported on SR, and parents reported on psychopathology symptoms. Results: Controlling for chronicity of maltreatment and child/adolescent sex effects, multiple mediation path analysis revealed that: 1) higher levels of physical and psychological abuse were associated with less externalizing problems through more negative social SR; 2) higher levels of physical neglect were associated with more externalizing problems through more positive opposition SR; 3) higher levels of psychological neglect were associated with less externalizing problems through more negative physical appearance SR, and 4) associated with more externalizing problems through more negative opposition SR. Moreover, the indirect effects of physical and psychological abuse on internalizing and externalizing problems through instrumental SR were conditional on child/adolescent age. Conclusion: Findings signal the relevance of preventing child/adolescent maltreatment and promoting the construction of positive and, foremost, realistic and adaptive self-representations as protection against maladjustment.info:eu-repo/semantics/publishedVersio

Sentiment classification of consumer generated online reviews using topic modeling

The development of the Internet and mobile devices enabled the emergence of travel and hospitality review sites, leading to a large number of customer opinion posts. While such comments may influence future demand of the targeted hotels, they can also be used by hotel managers to improve customer experience. In this article, sentiment classification of an eco-hotel is assessed through a text mining approach using several different sources of customer reviews. The latent Dirichlet allocation modeling algorithm is applied to gather relevant topics that characterize a given hospitality issue by a sentiment. Several findings were unveiled including that hotel food generates ordinary positive sentiments, while hospitality generates both ordinary and strong positive feelings. Such results are valuable for hospitality management, validating the proposed approach.info:eu-repo/semantics/acceptedVersio

Resilience of green roofs to climate change

The successful management of cities growth rely in part on the maximization of the benefits delivered by the built environment while minimizing the environmental degradation. Circular and resourceful cites are the mainstream for climate change resilience. Green roofs, as a nature-based solution, contribute to climate change adaptation and mitigation through the provision of several ecosystem services. Value of green roofs can be achieved at the level of environmental (e.g., air quality enhancement, carbon sequestration, biodiversity promotion stormwater management, acoustic insulation, and noise reduction), social (e.g., esthetic integration, well-being and life quality, rooftop gardens), and economic (e.g., life span extension, energetic efficiency, energy production, real-state valorization, business development) spheres. Buildup green roof resilience maybe underpinned by the selection of efficient and sustainable components for its installation. This chapter aims at giving an overview on the role of green roofs resilience to climate change, highlighting the provision of services and the mitigation and adaption capacity.info:eu-repo/semantics/acceptedVersio

Child Maltreatment Severity Questionnaire (MSQ) for professionals: development, validity, and reliability evidence

This article presents the development and validation of the child Maltreatment Severity Questionnaire (MSQ), aiming to contribute to increase the quality and efficiency of evaluation processes in the Child Protection System (CPS). To obtain a valid and reliable instrument, a set of studies was developed: Study 1—Based on two previous studies, the questionnaire was developed and the severity level of the items within maltreatment subtypes was assigned by 93 professionals from the welfare and CPS system. Consensus about the severity levels was assessed and described in terms of within-item reliability rankings; Study 2—The MSQ was filled out for 253 children and adolescents referred to the CPS. To ensure that the items within different subtypes of maltreatment were homogenous and had internal consistency, a reliability analysis was performed; Study 3—The MSQ was filled out for 1,000 children and adolescents referred to the CPS. This study involved testing validity evidence through an exploratory and a confirmatory factor analysis. We also analyzed the internal consistency, sensibility (i.e., sex and age differences) and concurrent validity of the MSQ. Findings support the adequacy and reliability of the MSQ to be used by CPS professionals in evaluating child maltreatment.info:eu-repo/semantics/acceptedVersio

Isolation and characterization of polymeric galloyl-ester- degrading bacteria from a tannery discharge place

The culturable bacteria colonizing the rhizosphere of plants growing in the area of discharge of a tannery effluent were characterized. Relative proportions of aerobic, denitrifying, and sulfate-reducing bacteria were determined in the rhizosphere of Typha latifolia, Canna indica, and Phragmites australis. Aerobic bacteria were observed to be the most abundant group in the rhizosphere, and plant type did not seem to influence the abundance of the bacterial types analyzed. To isolate bacteria able to degrade polyphenols used in the tannery industry, enrichments were conducted under different conditions. Bacterial cultures were enriched with individual polyphenols (tannins Tara, Quebracho, or Mimosa) or with an undefined mixture of tannins present in the tannery effluent as carbon source. Cultures enriched with the effluent or Tara tannin were able to degrade tannic acid. Six bacterial isolates purified from these mixed cultures were able to use tannic acid as a sole carbon source in axenic culture. On the basis of 16S ribosomal DNA sequence analysis, these isolates were closely related to organisms belonging to the taxa Serratia, Stenotrophomonas maltophilia, Klebsiella oxytoca, Herbaspirillum chlorophenolicum, and Pseudomonas putida

Youth-caregiver relationship quality in residential youth care: Professionals’ perceptions and experiences

This study aimed to explore the perceptions and experiences of professionals working in residential care (RC) settings (i.e., caregivers and directors) about youth-caregiver relationship quality (YCRQ). Method: A qualitative study was developed in Portugal including 15 caregivers (73.3% women, 23–50 years) and 15 directors (73.3% women, 34–45 years) working in 18 generalist RC units. Data were collected through six focus groups using a semi-structured interview script. Data were analyzed following a content analysis approach using NVIVO 12 software. Results: Our findings revealed that the concept of YCRQ in RC was mainly described in terms of good qualities, and the organizational determinants of YCRQ relationships were most mentioned both by caregivers and directors (i.e., organizational social context, intervention models and strategies). Individual characteristics of youth and staff were less described as determinants of YCRQ. These findings provide important insights for practice. Conclusions: efforts should be made to design interventions in RC that aim to improve its organizational social climate so as to provide caregivers with the necessary support and resources that enable them to enhance positive YCRQ.info:eu-repo/semantics/publishedVersio

Organizational social context and psychopathology of youth in residential care: the intervening role of youth‐caregiver relationship quality

Drawing on an ecological approach with multiple informants, this study investigated the mediating role of youth–caregiver relationship quality in associations between different features of residential care settings' organizational social context and youth's psychopathology. Participants were 378 youth aged between 12 and 25 years old, and 54 caregivers aged between 24 and 57 years old, from 29 generalist residential youth care settings in Portugal. Given the hierarchical structure of data, analyses were performed using multilevel modeling. Results revealed that organizational social contexts characterized by higher levels of engagement, stress, and centralization, as perceived by the caregivers, were associated with lower levels of youth's externalizing problems (e.g., aggressive behavior and delinquency), reported by the caregivers, via better youth–caregiver relationship quality, perceived by the youth in care. These findings highlight the relevance of creating an organizational social context in residential care settings that supports caregivers in establishing high-quality relationships with the youth in care, thereby promoting their mental health. This study contributes to the clarification of conflicting findings in previous studies of this field, by offering further empirical investigation of these issues.info:eu-repo/semantics/acceptedVersio

Treatment of tannery wastewater in a constructed wetlands operating in series with different plant species

The treatment of tannery wastewater has been a very important issue for pollution control in leather producing countries due to its high pollutant content. Biological processes offer a natural way of treating wastewaters, when compared to more aggressive types of treatment. Constructed wetlands can be an alternative to more conventional biological treatment systems. The species Phragmites australis, Typha spp, Scirpus spp. and Phalaris arundinacea are some of the plants frequently used in subsurface flow constructed wetlands. The present study aimed at assessing the performance of constructed wetland systems operating in series for the treatment of wastewater derived from a tannery plant. Pilot units were operated with horizontal subsurface flow and planted with Typha latifolia and Phragmites australis in an expanded clay matrix. They were subject to two different hydraulic loadings: 180mm/d and 60 mm/d. For an hydraulic loading of 180 mm/d, maximum removal efficiencies of 2100 KgCOD/had (48%) were achieved for unit 1 and 1500 KgCOD/had (33%) for unit 2. For an hydraulic loading of 60 mm/d, maximum removal efficiencies of 360 KgCOD/had (66%) were achieved for unit 1 and of 250 KgCOD/had (60%) for unit 2. No significant differences in performance were found between units with different plant species
