Sustainable water management requires an understanding of the effects of flow regulation on riparian ecomorphological processes. We investigated the transient response of Salix viminalis by examining the effect of water-level regimes on its above-ground and below-ground biomass. Four sets of Salix cuttings, three juveniles (in the first growing season) and one mature (1 year old), were planted and initially grown under the same water-level regime for 1 month. We imposed three different water-level regime treatments representing natural variability, a seasonal trend with no peaks, and minimal flow (characteristic of hydropower) consisting of a constant water level and natural flood peaks. We measured sap flux, stem water potential, photosynthesis, growth parameters, and final root architecture. The mature cuttings were not affected by water table dynamics, but the juveniles displayed causal relationships between the changing water regime, plant growth, and root distribution during a 2 month transient period. For example, a 50% drop in mean sap flux corresponded with a −1.5 Mpa decrease in leaf water potential during the first day after the water regime was changed. In agreement with published field observations, the cuttings concentrated their roots close to the mean water table of the corresponding treatment, allowing survival under altered conditions and resilience to successive stress events. Juvenile development was strongly impacted by the minimum flow regime, leading to more than 60% reduction of both above-ground and below-ground biomass, with respect to the other treatments. Hence, we suggest avoiding minimum flow regimes where Salix restoration is prioritized. [ABSTRACT FROM AUTHOR]

This study investigated how individualism, collectivism and conformity are associated with parenting and child adjustment in 1297 families with 10-year-old children from 13 cultural groups in nine countries. With multilevel models disaggregating between- and within-culture effects, we examined between- and within-culture associations between maternal and paternal cultural values, parenting dimensions and children's adjustment. Mothers from cultures endorsing higher collectivism and fathers from cultures endorsing lower individualism engage more frequently in warm parenting behaviours. Mothers and fathers with higher-than-average collectivism in their culture reported higher parent warmth and expectations for children's family obligations. Mothers with higher-than-average collectivism in their cultures more frequently reported warm parenting and fewer externalising problems in children, whereas mothers with higher-than-average individualism in their culture reported more child adjustment problems. Mothers with higher-than-average conformity values in their culture reported more father-displays of warmth and greater mother-reported expectations for children's family obligations. Fathers with higher-than-average individualism in their culture reported setting more rules and soliciting more knowledge about their children's whereabouts. Fathers who endorsed higher-than-average conformity in their culture displayed more warmth and expectations for children's family obligations and granted them more autonomy. Being connected to an interdependent, cohesive group appears to relate to parenting and children's adjustment., (© 2024 International Union of Psychological Science.)

Introduction: Creating romantic relationships characterized by high-quality, satisfaction, few conflicts, and reasoning strategies to handle conflicts is an important developmental task for adolescents connected to the relational models they receive from their parents. This study examines how parent-adolescent conflicts, attachment, positive parenting, and communication are related to adolescents' romantic relationship quality, satisfaction, conflicts, and management., Method: We interviewed 311 adolescents at two time points (females = 52%, ages 15 and 17) in eight countries (China, Colombia, Italy, Kenya, the Philippines, Sweden, Thailand, and the United States). Generalized and linear mixed models were run considering the participants' nesting within countries., Results: Adolescents with negative conflicts with their parents reported low romantic relationship quality and satisfaction and high conflicts with their romantic partners. Adolescents experiencing an anxious attachment to their parents reported low romantic relationship quality, while adolescents with positive parenting showed high romantic relationship satisfaction. However, no association between parent-adolescent relationships and conflict management skills involving reasoning with the partner was found. No associations of parent-adolescent communication with romantic relationship dimensions emerged, nor was there any effect of the country on romantic relationship quality or satisfaction., Conclusion: These results stress the relevance of parent-adolescent conflicts and attachment as factors connected to how adolescents experience romantic relationships., (© 2024 Foundation for Professionals in Services to Adolescents.)

Communicative openness (CO) defines the willingness of parents and children to explore the significance of adoption. Especially in the first year of adoption, CO could be challenging for adoptive parents, who are influenced by personal characteristics. Using a retrospective assessment, we investigated parents' communicative experiences in the first year of adoption and whether these are affected by romantic attachment and empathy. In the study, 290 adoptive parents (females = 73%, mean age 50 years) filled (a) an ad hoc questionnaire for CO, (b) Experiences in Close Relationships-Revised (ECR-R) for attachment, and the (c) Interpersonal Reactivity Index (IRI) for empathy. During the first year, most parents reported difficulties in controlling their emotions and understanding their children's emotions. Parents with an avoidant attachment and personal distress in empathy were more likely to feel fatigued in sharing and controlling personal feelings and understanding their children's feelings. Open adoption-related communication is a complex and challenging process for adoptive parents, which can be facilitated or not by individual characteristics such as avoidant attachment and personal distress in emotional situations. These results could help develop psychological interventions targeting adoptive parents during the first year after the child enters the family system.

Hikikomori is a severe form of social withdrawal increasing among the young Italian population. Hikikomori has been connected to psychological problems and high environmental sensitivity. Nevertheless, only a few studies have been carried out in the Italian context, and they did not analyze several aspects strictly related to the hikikomori phenomenon, such as the role of attachment and sensitivity. We aimed to investigate the relationship between attachment, sensitivity, and psychological problems in a sample of Italian hikikomori. Our sample comprised 72 Italian adolescents and young adults (49 males and 23 females), meanly aged 22.5 years, recruited through online forums and clinical centers for the hikikomori phenomenon. Our participants fulfilled the Highly Sensitive Person Scale (HSPS), the Attachment Style Questionnaire (ASQ), and the Hopkins Symptom Checklist (SCL-90-R). The results showed high psychological issues (i.e., depression and anxiety), environmental sensitivity, and insecure attachment orientations. Moreover, we discovered a significant relationship between attachment dimensions, environmental sensitivity, and psychopathology. Our study sheds light on a novel research path and could help both the researchers and the clinicians who work with people suffering from social withdrawal.

Catalytic oxidations of tricyclic endo -norbornene-fused tetrahydrofuran with bimetallic nanoclusters Cu/Au-PVP and H 2 O 2 or t -BuOOH as an oxidant provided C-H bond oxidation adjacent to the ether function and 4-oxa-tricyclo[5.2.1.0]-8,9- exo -epoxydecane ( 4 ), however, oxidation with Pd/Au-PVP took place at the C=C function giving epoxide 4 and oxidative three-bond forming dimeric product, dodecahydro-1,4:6,9-dimethanodibenzofurano[2,3-b:7,8-b']bisoxolane ( 5 ). Formation of the latter suggests the involvement of a reactive Pd-C intermediate. Similarly, oxidative C-C bond forming reactions were found in cycloaddition reactions of N 2-Boc-1,2,3,4-tetrahydro-γ-carbolines and 2,3-dihydroxybenzoic acid with 2 - 5 mol% Cu/Au-PVP and H 2 O 2 at 25 °C, providing two-bond-forming [4+2] cycloadducts. Under similar reaction conditions, Pd/Au-PVP did not produce the cycloadduct, indicating a need of complexation between Cu with the carboxylic acid group of 2,3-dihydroxybenzoic acid and allylic amine function of γ-carbolines in the cyclization reaction. The reported intermolecular coupling reactions using Pd/Au-PVP or Cu/Au-PVP nanocluster catalysts under oxidative conditions at 25 °C are unprecedented.

Infertility impacts several life dimensions. Among them, sexuality is particularly affected; yet studies have mainly focused on infertile women. We aimed to explore infertile men's and women's experiences in sexual satisfaction, internal control, and anxiety, and the relationship between attachment, dyadic adjustment, and sexuality. The sample consisted of 129 infertile people (47.3% females, 52.7% males, M age = 39 years) who fulfilled an ad hoc questionnaire, the Multidimensional Sexuality Questionnaire (MSQ), the Experiences in Close Relationship-Revised (ECR-R), and the Dyadic Adjustment Scale (DAS). We found a significant effect of type of infertility and infertility factors on sexual anxiety only in infertile men. As regards infertile women, dyadic adjustment predicted sexual satisfaction, anxious attachment decreased sexual internal control, and avoidant attachment reduced sexual anxiety. As regards infertile men, high dyadic adjustment increased sexual satisfaction and a high avoidant attachment predicted high levels of sexual internal control. There was no relationship between attachment, dyadic adjustment, and sexual anxiety for infertile men. From the results, it emerges how important is to consider both dyadic adjustment and attachment in studying how infertility impacts women's and men's lives.

A mother's responses to her newborn and her confidence in the child's caretaking depend on her attachment security, general parental stress, and perceived self-efficacy. However, few studies have analyzed maternal confidence in caretaking and how it is influenced by some mothers' characteristics. We aimed to examine the association between maternal adult attachment and confidence in a child's caretaking and to understand whether this relationship was mediated by parenting stress and maternal self-efficacy. The sample consisted of 96 mothers with a mean age of 33 years with newborn children aged between 3 and 30 days. The instruments used were the Experiences in Close Relationships-Revised (ECR-R), the Mother and Baby Scale (MABS), the Parenting Stress Index Short Form (PSI-SF), and the Maternal Self-Efficacy Questionnaire (MEQ). The results showed a positive association between attachment avoidance and lack of confidence in caretaking, and this association was mediated by parenting stress. Conversely, attachment anxiety appeared not to influence confidence in caretaking, and maternal self-efficacy did not appear to mediate the relationship between attachment and confidence in the caretaking of infants. Our results could guide new research in studying confidence in caretaking and enable healthcare professionals to recognize at-risk situations early from the first month after childbirth.

Second-generation chiral-substituted poly- N -vinylpyrrolidinones (CSPVPs) (-)- 1R and (+)- 1S were synthesized by free-radical polymerization of (3a R ,6a R )- and (3a S ,6a S )-5-ethenyl-tetrahydro-2,2-dimethyl-4 H -1,3-dioxolo[4,5- c ]pyrrol-4-one, respectively, using thermal and photochemical reactions. They were produced from respective d -isoascorbic acid and d-ribose. In addition, chiral polymer (-)- 2 was also synthesized from the polymerization of ( S )-3-(methoxymethoxy)-1-vinylpyrrolidin-2-one. Molecular weights of these chiral polymers were measured using HRMS, and the polymer chain tacticity was studied using 13 C NMR spectroscopy. Chiral polymers (-)- 1R , (+)- 1S , and (-)- 2 along with poly- N -vinylpyrrolidinone (PVP, MW 40K) were separately used in the stabilization of Cu/Au or Pd/Au nanoclusters. CD spectra of the bimetallic nanoclusters stabilized by (-)- 1R and (+)- 1S showed close to mirror-imaged CD absorption bands at wavelengths 200-300 nm, revealing that bimetallic nanoclusters' chiroptical responses are derived from chiral polymer-encapsulated nanomaterials. Chemo-, regio-, and stereo-selectivity was found in the catalytic C-H group oxidation reactions of complex bioactive natural products, such as ambroxide, menthofuran, boldine, estrone, dehydroabietylamine, 9-allogibberic acid, and sclareolide, and substituted adamantane molecules, when catalyst Cu/Au (3:1) or Pd/Au (3:1) stabilized by CSPVPs or PVP and oxidant H 2 O 2 or t -BuOOH were applied. Oxidation of (+)-boldine N -oxide 23 using NMO as an oxidant yielded 4,5-dehydroboldine 27 , and oxidation of (-)-9-allogibberic acid yielded C6,15 lactone 47 and C6-ketone 48 .

Same-Sex Intimate Partner Violence (SSIPV) among lesbian women has been underestimated until few decades ago. While the association between romantic attachment and SSIPV has been widely demonstrated, mechanisms that mediate this association and the complex relationships between romantic attachment, SSIPV, and SSIPV-specific risk factors have not been adequately investigated to date. The current study assessed the influence of romantic attachment on SSIPV perpetration among lesbian women, exploring the mediating role of internalized homonegativity within this association. Three hundred and twenty-five Italian lesbian women with a mean age of 30 years were recruited and completed the following self-report measures: the Experiences in Close Relationships-Revised (ECR-R), the Measure of Internalized Sexual Stigma, and the Revised Conflict Tactics Scale Short Form. The results showed a positive association between attachment anxiety, and general and psychological SSIPV perpetration. Similarly, attachment avoidance was positively related with general, psychological, and physical SSIPV perpetration. The association between romantic attachment, and general and psychological SSIPV was partially mediated by internalized homonegativity. These findings have theoretical implications and provide valuable information to implement services and interventions tailored for SSIPV, to date scarce and not effective., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Tognasso, Trombetta, Gorla, Ramon, Santona and Rollè.)

Adolescence is characterized by several transformations, such as identity construction, progressive estrangement from parents, relational interest in peers, and body changes that also involve sexuality issues. In this process, attachment patterns play a fundamental role in relationships, and when these are dysfunctional, they can result in internalizing and externalizing problems. Often, females show their relational difficulties through internalizing expressions and males through externalizing expressions. Additionally, given the sexual progress involved in this life moment, psychological symptomatology may influence adolescents' perception of sex and performance. Our purpose is to study the mediating role of internalizing and externalizing symptomatology in the relationship between attachment patterns and sexual and psychological dimensions. In addition, we investigated the moderating effect of the sex assigned at birth on this mediation model. n = 493 adolescents (38.3% males; Mage = 16.51; SD = 1.17) participated in the study. The results show a significant mediation effect of internalizing symptomatology on the relationship between attachment and sexual anxiety. Additionally, this effect is moderated significantly by assigned-at-birth sex. These results confirm that in adolescence, attachment patterns can influence adolescents' perception of sex. The connection between these two psychological dimensions is influenced by symptomatologic expression. Further investigations are needed.

Communicative openness within the adoptive family changes over time and helps the child explore his/her history. We aimed to evaluate whether adoptive families communicate about specific adoption-related themes from the beginning of their lives as a family. We created an instrument to track the communication process during the first year of adoption, involving a sample of 537 internationally adopted children (313 males, 224 females, mean age of adoption: 4.9 years) at two time points: six (T1) and twelve (T2) months after adoption. Our results suggest that in the first year of placement, children express memories about the past but tend to not speak about their birth families. We discovered a significant difference (Wald test = 4.889; p = 0.027) in communication about the biological family between the two points. The presence of adoptive parents who speak about it impacts the child's questions about the past (exp (B) = 2.452, p = 0.006) and whether the child speaks about his/her biological family (exp (B) = 2.373; p = 0.017). Then, in the first year of adoption, the presence of an adoptive parent who communicates openly helps the child to ask questions and share his/her thoughts.

The aim of this study was to compare the use of beta-tricalcium phosphate (β-TCP) (chronOS) with autogenous bone grafts alone in maxillary sinus elevation surgery. The test samples were β-TCP alone, β-TCP mixed with autogenous bone grafts (1:1), and autogenous bone grafts alone. Twelve maxillary sinuses were grafted with β-TCP (group 1), nine with β-TCP+autogenous bone graft (group 2), and 12 with autogenous bone graft (group 3). After 6 months, biopsies were obtained concurrent to the placement of dental implants; these were subjected to histomorphometric analysis and immunohistochemical analysis for runt-related transcription factor 2 (RUNX2) and vascular endothelial growth factor (VEGF). The average bone formation in group 1 was 46.3±11.6% in the pristine bone region, 47.6±9.9% in the intermediate region, and 44.8±22.1% in the apical region; in group 2, values were 35.0±15.8%, 32.5±13.7%, and 32.8±16.0%, respectively; in group 3, values were 43.1±16.0%, 31.0±13.0%, and 46.1±16.3%, respectively. Immunostaining of samples in group 2 showed high cellular activity and immature bone; this differed from groups 1 and 3, in which mature bone was demonstrated. Thus, this study showed that β-TCP presents the same behaviour as autogenous bone graft, which makes it a good bone substitute., (Copyright © 2017 International Association of Oral and Maxillofacial Surgeons.

Two new C 2 -symmetric N,N'-benzylated bis(amino amides) have been synthesised and their interaction with different transition metals studied using a variety of techniques including UV-Vis and CD spectroscopy or ESI-MS. The determination of the corresponding stability constants with Cu 2+ has been possible, in H 2 O/CH 3 CN 7/3 v/v, for one of these ligands (4) using potentiometric titrations. The results obtained reveal that N-benzylation affords significant changes to their properties and is accompanied by an appreciable decrease in the corresponding complexation stability constants. However, this, along with the low kinetics associated to Ni 2+ , facilitates the recognition of Cu 2+ by 4 that can be followed by the naked-eye up to the submillimolar range. Very interestingly, the chiral nature of this ligand provides an intense and well defined CD curve for the corresponding Cu 2+ complex, very sensitive to the coordination geometry, facilitating the analysis of this interaction even at the μM range. The formation by both ligands (3 and 4) of square planar complexes with Cu 2+ and Ni 2+ displaying a 1 : 1 stoichiometry was confirmed by their X-ray crystal structures.

Two new tetradentate C2-symmetric pseudopeptidic ligands derived from Val and Phe containing two amino and two amido groups and a central o-substituted aromatic spacer have been prepared. Their complexes with Cu(2+), Zn(2+), and Ni(2+) have been studied by potentiometry, UV-vis spectrophotometry, FT-IR, and ESI-MS. The presence of the aromatic spacer provides Cu(2+) complexes with stability constants several orders of magnitude higher than those observed for related ligands containing aliphatic central spacers. Besides, the formation of [MH-2L] complex species is favored. Crystal structures for the corresponding Cu(2+) and Ni(2+) have been obtained, revealing the metal atom in an essentially square-planar geometry, although, in several instances, the oxygen atom of an amide carbonyl of a second complex species can act as a fifth coordination site. In the case of Zn(2+), the only crystal structure obtained displays a square-pyramidal arrangement of the metal center. Finally, preliminary experiments show the catalytic activity of some of these complexes, in particular, Zn(2+) complexes, for epoxide ring-opening with using aniline as the nucleophile in a ligand accelerated process.

The correction of bone defects can be performed using autogenous or alloplastic materials, such as beta-tricalcium phosphate (β-TCP). This study compared the changes in bone volume (CBV) after maxillary sinus lifting using autogenous bone (n = 12), autogenous bone associated with β-TCP 1:1 (ChronOS; DePuy Synthes, Paoli, CA, USA) (n = 9), and β-TCP alone (n = 11) as grafting material, by means of cone beam computed tomography (CBCT). CBV was evaluated by comparing CBCT scans obtained in the immediate postoperative period (5-7 days) and at 6 months postoperative in each group using OsiriX software (OsiriX Foundation, Geneva, Switzerland). The results showed an average resorption of 45.7 ± 18.6% for the autogenous bone group, 43.8 ± 18.4% for the autogenous bone+β-TCP group, and 38.3 ± 16.6% for the β-TCP group. All bone substitute materials tested in this study presented satisfactory results for maxillary sinus lifting procedures regarding the maintenance of graft volume during the healing phase before the insertion of implants, as assessed by means of CBCT., (Copyright © 2015 International Association of Oral and Maxillofacial Surgeons.

Ferrous and non-ferrous metal scraps are increasingly recovered from municipal solid waste incineration bottom ash and used in the production of secondary steel and aluminium. However, during the incineration process, metal scraps contained in the waste undergo volatilisation and oxidation processes, which determine a loss of their recoverable mass. The present paper evaluates the behaviour of different types of aluminium packaging materials in a full-scale waste to energy plant during standard operation. Their partitioning and oxidation level in the residues of the incineration process are evaluated, together with the amount of potentially recoverable aluminium. About 80% of post-consumer cans, 51% of trays and 27% of foils can be recovered through an advanced treatment of bottom ash combined with a melting process in the saline furnace for the production of secondary aluminium. The residual amount of aluminium concentrates in the fly ash or in the fine fraction of the bottom ash and its recovery is virtually impossible using the current eddy current separation technology. The average oxidation levels of the aluminium in the residues of the incineration process is equal to 9.2% for cans, 17.4% for trays and 58.8% for foils. The differences between the tested packaging materials are related to their thickness, mechanical strength and to the alloy., (Copyright © 2012 Elsevier Ltd. All rights reserved.)
