Multivariate growth trajectories of parenting practices in adolescence predicting young adult relationships with parents.

Guided by the life course perspective, this study investigated the developmental antecedents of contact, closeness/warmth, and negativity in young adults' relationships with their parents. Taking the developmental systems approach, we considered interindividual differences in not only initial levels of parenting quality in early adolescence (Grade 6) but also developmental changes in parenting quality across adolescence (Grades 6-12) as predictors of young adult-parent relationship quality. Data were from a large sample of young adults (N = 1,631; Mage = 22.84; 57% female; 90% White; 25% received free/reduced-price school lunch in Grade 6) followed from the fall of Grades 6 to 12 at eight time points, plus a young adult assessment. Using multivariate latent growth curve modeling, we identified a nuanced pattern of predictors of the three relationship dimensions. Higher initial levels of and lower rates of decline in parental involvement across adolescence predicted more young adult contact with mothers and fathers. Higher initial levels of parental warmth and parental involvement, as well as lower rates of decline in parental warmth, predicted greater closeness/warmth with mothers and fathers in young adulthood. Higher initial levels of and lower rates of decline in effective discipline predicted less young adult negativity toward mothers and fathers. These results held even when accounting for important adolescent and young adult covariates (adolescent sex and race, adolescent family income and structure, adolescent aggressive behavior tendencies, young adult living arrangement). The study offers new insights into how parenting practices in adolescence contribute to parent-child relationship in young adulthood. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The effect of the PROSPER partnership model on cultivating local stakeholder knowledge of evidence-based programs: a five-year longitudinal study of 28 communities.

A substantial challenge in improving public health is how to facilitate the local adoption of evidence-based interventions (EBIs). To do so, an important step is to build local stakeholders' knowledge and decision-making skills regarding the adoption and implementation of EBIs. One EBI delivery system, called PROSPER (PROmoting School-community-university Partnerships to Enhance Resilience), has effectively mobilized community prevention efforts, implemented prevention programming with quality, and consequently decreased youth substance abuse. While these results are encouraging, another objective is to increase local stakeholder knowledge of best practices for adoption, implementation and evaluation of EBIs. Using a mixed methods approach, we assessed local stakeholder knowledge of these best practices over 5 years, in 28 intervention and control communities. Results indicated that the PROSPER partnership model led to significant increases in expert knowledge regarding the selection, implementation, and evaluation of evidence-based interventions. Findings illustrate the limited programming knowledge possessed by members of local prevention efforts, the difficulty of complete knowledge transfer, and highlight one method for cultivating that knowledge.

Quantum fingerprinting.

Classical fingerprinting associates with each string a shorter string (its fingerprint), such that any two distinct strings can be distinguished with small error by comparing their fingerprints alone. The fingerprints cannot be made exponentially smaller than the original strings unless the parties preparing the fingerprints have access to correlated random sources. We show that fingerprints consisting of quantum information can be made exponentially smaller than the original strings without any correlations or entanglement between the parties. This implies an exponential quantum/classical gap for the equality problem in the simultaneous message passing model of communication complexity.

Experimental realization of an order-finding algorithm with an NMR quantum computer.

We report the realization of a nuclear magnetic resonance quantum computer which combines the quantum Fourier transform with exponentiated permutations, demonstrating a quantum algorithm for order finding. This algorithm has the same structure as Shor's algorithm and its speed-up over classical algorithms scales exponentially. The implementation uses a particularly well-suited five quantum bit molecule and was made possible by a new state initialization procedure and several quantum control techniques.

Notes on ventricular tachycardia occurring during magnet waving and on the function of the Omni-Ectocor pacemaker.

Magnet waving was performed in a patient with a normally functioning, program-mable, QRS-inhibited (VVI) pacemaker (Omni-Stanicor, Cordis Corporation), which was implanted for sick sinus syndrome. This procedure resulted in reversion to an asynchronous, nonsensing (irregular VOO) mode of operation with uneven stimulus-to-stimulus intervals. A short run of ventricular tachycardia occurred when a stimulus fell on the T wave of the preceding ectopic ventricular beat. This tachycardia was short-lived and was probably terminated by a single pacemaker stimulus. It is also suggested that magnet waving and external chest wall stimulation in patients with Omni-Ectocor and Starr--Edwards pacemakers require further study and that electrocardiograms recorded from patients in whom they have been implanted have to be analyzed taking into consideration that these pacemakers have features common to both, QRS-triggered (VVT), and QRS-inhibited (VVI) pacemakers.
