PURPOSE: Mechanisms of early stone retention within the kidney are understudied and poorly understood. To date, attachment via Randall's plaque is the only widely accepted theory in this regard, best described in idiopathic calcium oxalate stone formers. Brushite stone formers are known to have distinct papillary morphology relative to calcium oxalate stone formers. As such, we sought to determine whether stone attachment mechanisms in such patients may be similarly unique. MATERIALS AND METHODS: Patients undergoing percutaneous and or ureteroscopic procedures for stone removal were consented for endoscopic renal papillary examination and individual stone collection...

It has been previously indicated that BN nanostructures may be nontoxic and biocompatible. Here the potential application of a B24N24 is explored as a drug delivery system for anti-cancer 5-fluorouracil based on the density functional theory. This drug prefers to attach via its oxygen atoms to the B atoms of the cluster with adsorption energy about -11.90kcalmol(-1) based on the dispersion corrected B3LYP level of theory. To make the cluster more appropriate for drug delivery, we replaced a B atom by Si or Al atom to improve the interaction strength...

A very large literature links the experiences of marital separation and divorce to risk for a range of poor distal health outcomes, including early death. What is far less clear, however, is the mechanistic pathways that convey this risk. Several plausible mechanisms are identified in the literature, and the central thesis of this paper is that the empirical study of divorce and health will benefit enormously from a renewed reliance on theory to dictate how these mechanisms of action may unfold over time. This review emphasizes the roles of attachment and social baseline theories in making specific mechanistic predictions and highlights the ways in which these perspectives can contribute new empirical knowledge on risk and resilience following marital dissolution...

Chronic illness and the death of a romantic partner are two of the most significant stressors reported by older adults, resulting in various physical and mental health consequences. Evidence suggests that social support is a key factor in understanding the association between chronic illness and widowhood and the wellbeing of older adults. Nevertheless, research into social support is often approached in an atheoretical manner when investigating these stressors in older adulthood. We attempt to address this theoretical chasm by proposing an integrative model to explain social support processes in older couples which draws on models of social support and attachment theory...

Emotionally Focused Therapy for Couples (EFT) is an evidence-based couple therapy based in attachment theory. Research has amassed over the past three decades pointing to the role of relationships in health and and well-being. Affective neuroscience suggests that secure relationships appear to foster adaptive stress co-regulation. The effectiveness of EFT has been demonstrated in couples facing high levels of stress, and has been shown to reduce depressive and post-traumatic stress symptoms. Furthermore, EFT has been shown to help couples regulate their neurophysiological stress response...

REVIEW
Judith A Feeney, Gery C Karantzas
The experience of conflict is often cited as a highly stressful relational phenomenon by romantic couples, and can have negative implications for relationship satisfaction and for the longevity of romantic relationships. In this paper, we review extant research on couple conflict in romantic relationships from an attachment theory perspective. The research we review is underpinned by two central tenets: firstly, severe or persistent conflict activates the attachment system; secondly, responses to couple conflict involve complex attachment dynamics, shaped by partners' attachment anxiety and avoidance...

Jeffry A Simpson, W Steven Rholes
In this article, we discuss theory and research on how individuals who have insecure adult romantic attachment orientations typically think, feel, and behave when they or their romantic partners encounter certain types of chronic or acute stress. We first review basic principles of attachment theory and then discuss how two forms of attachment insecurity-anxiety and avoidance-are associated with unique patterns of emotion regulation in response to certain types of threatening/distressing situations. We then discuss a Diathesis-Stress Process Model that has guided our research, highlighting studies that provide support for certain pathways of the model...

Adult attachment theory provides guidance for providing optimal social support in intimate relationships. According to attachment theory, facilitating autonomy (secure base support) sometimes is more important than providing nurturance (safe haven support). In addition, it is important that couples celebrate one another's triumphs and successes (another form of secure base support). A key construct that explains the development of attachment is responsiveness to the individual's needs. Support that is delivered in a responsive manner (i...

Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD) is a social-learning and attachment-based intervention using video feedback to support sensitive parenting and at the same time setting firm limits. Empirical studies and meta-analyses have shown that sensitive parenting is the key determinant to promote secure child-parent attachment relationships and that adequate parental discipline contributes to fewer behavior problems in children. Building on this evidence, VIPP-SD has been tested in various populations of at-risk parents and vulnerable children (in the age range of zero to six years), as well as in the context of child care...

Attachment is a key subfield in the area of parenting and parent-child relationships research. In this brief overview, we summarise what we consider to be the state-of-the-art of attachment research, focusing primarily on the nature and significance of attachment in infancy and early childhood. We review 4 major topics that are central issues in the scientific literature on attachment: (1) the role of the environment in the development of attachment, (2) the intergenerational transmission of patterns of attachment, (3) the stability of attachment patterns through early adulthood, and (4) the role of attachment in adjustment and maladjustment...

Within the theoretical framework of attachment theory, the author examined associations between adolescents' procrastination and their attachment relationships with both mothers and fathers, and explored the potential mediation role of self-worth in these associations. Participants were 384 Chinese adolescents (49.6% boys, average age 15.13 years) from public schools in Shanghai, China. They completed self-report measures of 3 dimensions of parental attachment (i.e., trust, communication, and alienation), general self-worth, and procrastination...

We tested the association between the palliative patient's attachment style and the patient-doctor relationship, by means of Revised Adult Attachment Scale and a self-designed, patient-doctor relationship questionnaire. The study included 110 (52 M, 58 F) cancer, hospice patients, aged 36-80 years. We observed 54 percent of secure, 18 percent of dismissive, 9 percent of preoccupied, and 19 percent of fearful styles. Securely attached patients developed significantly ( p < .05) better relationships with doctors than insecure patients...

We report the generation of deoxyriboadenosine dinucleotide cation radicals by gas-phase electron transfer to dinucleotide dications and their non-covalent complexes with crown ether ligands. Stable dinucleotide cation radicals of a novel hydrogen-rich type were generated and characterized by tandem mass spectrometry and UV-vis photodissociation (UVPD) action spectroscopy. Electron structure theory analysis indicated that upon electron attachment the dinucleotide dications underwent a conformational collapse followed by intramolecular proton migrations between the nucleobases to give species whose calculated UV-VIS absorption spectra matched the UVPD action spectra...

To discern the catalytic activity of different active sites, a self-assembly strategy is applied to confine the involved species that are "attached" to specific surface sites. The employed probe reaction system is the Ullmann coupling of 4-bromobiphenyl, C6H5C6H4Br, on an atomically flat Ag(111) surface, which is explored by combined scanning tunneling microscopy, synchrotron X-ray photoelectron spectroscopy, and density functional theory calculations. The catalytic cycle involves the detachment of the Br atom from the initial reactant to form an organometallic intermediate, C6H5C6H4AgC6H4C6H5, which subsequently self-assembles with its central Ag atom residing either on 2-fold bridge or 3-fold hollow sites at full coverage...

BACKGROUND: Previous research has documented increased incidence of insecure attachment and theory of mind (ToM) deficits in individuals experiencing psychotic disorders. ToM has been theorized as a possible mediator of the relation between attachment and psychosis (Korver-Nieberg et al., 2014). The current study sought to extend this area of research to adolescents for the first time by examining adolescent-parent attachment and ToM in inpatient adolescents. METHODS: Participants were 362 inpatient adolescents and their parents; participants completed the Child Attachment Interview, Movie for the Assessment of Social Cognition, Youth Self Report, and Child Behavior Checklist...

OBJECTIVES: Developing compassion towards oneself has been linked to improvement in many areas of psychological well-being, including psychosis. Furthermore, developing a non-judgemental, accepting way of relating to voices is associated with lower levels of distress for people who hear voices. These factors have also been associated with secure attachment. This study explores associations between the constructs of mindfulness of voices, self-compassion, and distress from hearing voices and how secure attachment style related to each of these variables...

This study aims to determine relationships between intrapartum factors, neonatal characteristics, skin-to-skin contact (SSC), and early breastfeeding initiation after spontaneous vaginal and Caesarean section or operative vaginal birth. A total of 915 mother-newborn dyads were considered in a hypothetical model based on integrated concepts of breastfeeding initiation model, infant learning framework, and attachment theory. Multiple-group path analysis was used to determine whether differences exist between effects of immediate SSC (≤30 min) on early breastfeeding initiation in different modes of birth...

Research examining the development of online addictions has grown greatly over the last decade with many studies suggesting both risk factors and protective factors. In an attempt to integrate the theories of attachment and identity formation, the present study investigated the extent to which identity styles and attachment orientations account for three types of online addiction (i.e., internet addiction, online gaming addiction, and social media addiction). The sample comprised 712 Italian students (381 males and 331 females) recruited from schools and universities who completed an offline self-report questionnaire...

A polymeric ionic liquid (PIL), with quaternary ammonium ions attached to the polymer matrix, displays CO2 affinity controlled by moisture. This finding led to the development of moisture swing absorption (MSA) for direct air capture (DAC) of CO2. This work aims to elucidate the role of water in MSA. For some humidity range, CO2 absorption is an endothermic process associated with concurrent dehydration of the sorbent. The thermodynamic behavior of water indicates a decreased hydrophilicity of the PIL as the mobile anion transforms from CO32- to HCO3- during CO2 absorption...

This article examines the construct of disorganized attachment originally proposed by Main and Solomon, developing some new conjectures based on inspiration from a largely unknown source: John Bowlby's unpublished texts, housed at the Wellcome Trust Library Archive in London (with permission from the Bowlby family). We explore Bowlby's discussions of disorganized attachment, which he understood from the perspective of ethological theories of conflict behavior. Bowlby's reflections regarding differences among the behaviors used to code disorganized attachment will be used to explore distinctions that may underlie the structure of the current coding system...
