We investigated insecure attachment in relation to how actively romantic partners expect to participate in couple therapy (role expectations for self and partner) and, consequently, how much they expect to benefit from doing so (outcome expectations). Specifically, we used the mediated actor-partner interdependence model (Ledermann et al., 2011) with archived data from 297 heterosexual couples in a research-practice network (L.

Article Synopsis
  • HyperArc (HA) auto-planning simplifies the creation of high-quality Stereotactic Radiosurgery (SRS) plans, while the "Ask For It" (AFI) manual planning method also aims for low intermediate dose spill and high target dose conformity.
  • A comparison using 54 created target volumes (PTVs) showed both AFI and HA methods were used across a variety of case complexities to evaluate treatment plan quality.
  • Results revealed that AFI outperformed HA in several quality metrics, although HA provided better dose coverage, suggesting both methods can yield effective planning outcomes.

The very high theoretical specific energy of the lithium-air (Li-O) battery (3500 Wh kg) compared with other batteries makes it potentially attractive, especially for the electrification of flight. While progress has been made in realizing the Li-air battery, several challenges remain. One such challenge is achieving a high capacity to store charge at the positive electrode at practical current densities, without which Li-air batteries will not outperform lithium-ion.

The global impact of the SARS-COV-2 pandemic necessitated a rapid shift to online/teletherapy psychotherapy services. While research suggests the feasibility and efficacy of teletherapy, there is limited investigation into couple teletherapy's impact on satisfaction and therapeutic alliance. This study aimed to address this gap by examining changes in couple satisfaction during tele- and in-person therapy sessions over 12 sessions and exploring whether therapeutic alliance development mediates these changes.

The lithium-air (Li-air) battery offers one of the highest practical specific energy densities of any battery system at >400 W h kg. The practical cell is expected to operate in air, which is flowed into the positive porous electrode where it forms LiO on discharge and is released as O on charge. The presence of CO and HO in the gas stream leads to the formation of oxidatively robust side products, LiCO and LiOH, respectively.

Introduction: Non-carious cervical lesions (NCCLs) are considered to have a multi-factorial aetiology and their management is affected by a range of variables perhaps most importantly clinical judgement. The aim of this study was to elicit information from practicing dentists, using interviews, to explore their understanding of NCCL aetiology, the decision-making criteria of when to restore, and the restorative techniques used to restore NCCLs. This may help identify gaps or anomalies in our understanding to inform future research and clinical practice for the management of NCCLs.

Although Li-air rechargeable batteries offer higher energy densities than lithium-ion batteries, the insulating LiO formed during discharge hinders rapid, efficient re-charging. Redox mediators are used to facilitate LiO oxidation; however, fast kinetics at a low charging voltage are necessary for practical applications and are yet to be achieved. We investigate the mechanism of LiO oxidation by redox mediators.

Since 2021, some state legislators have passed laws that limit what public institutions can teach about discrimination. The number of these laws, also called gag orders, is increasing despite a national outcry against racism, homophobia and transphobia, and other forms of discrimination. Many nursing and other professional healthcare organizations have recognized and published statements decrying racism in healthcare and calling for an increased focus on health disparities and advancing health equity.

During the past 50 years, medical and behavioral scientists have made great progress in understanding the variables which influence the development of sexual orientation, identity, and consequent behavior. In most instances, homosexuality is influenced by hormonal, genetic, and immunologic variables during fetal development, and the effects cannot usually be altered without consequence. The recent struggle within The United Methodist Church in the USA reflects the difficulty that society in general has with accepting homosexuality as part of the spectrum of sexuality.

Understanding ion transport in solid materials is crucial in the design of electrochemical devices. Of particular interest in recent years is the study of ion transport across 2-dimensional, atomically thin crystals. In this contribution, we describe the use of a host-guest hybrid redox material based on polyoxometalates (POMs) encapsulated within the internal cavities of single-walled carbon nanotubes (SWNTs) as a model system for exploring ion transport across atomically thin structures.

The mixing of [V O ] decavanadate anions with a dicationic gemini surfactant (gem) leads to the spontaneous self-assembly of surfactant-templated nanostructured arrays of decavanadate clusters. Calcination of the material under air yields highly crystalline, sponge-like V O (gem-V O ). In contrast, calcination of the amorphous tetrabutylammonium decavanadate allows isolation of a more agglomerated V O consisting of very small crystallites (TBA-V O ).
