Prevalence, Antecedents, and Consequences of Workplace Bullying among Nurses-A Summary of Reviews.

Despite over 25 years of extensive research about the workplace bullying phenomenon in various disciplines, there have been mixed conclusions about its prevalence, antecedents, and consequences among nurses reported by multiple systematic reviews. This summary review used the Cochrane's Overview of Reviews method to examine the prevalence, antecedents, coping behaviors, and consequences of workplace bullying among nurses to understand the interplay of these variables in healthcare workplace contexts. A total of 12 systematic reviews published between 2013 and 2020 were included based on the eligibility criteria.

Chromatin-modifying genetic interventions suppress age-associated transposable element activation and extend life span in Drosophila.

Transposable elements (TEs) are mobile genetic elements, highly enriched in heterochromatin, that constitute a large percentage of the DNA content of eukaryotic genomes. Aging in Drosophila melanogaster is characterized by loss of repressive heterochromatin structure and loss of silencing of reporter genes in constitutive heterochromatin regions. Using next-generation sequencing, we found that transcripts of many genes native to heterochromatic regions and TEs increased with age in fly heads and fat bodies.

Differential effects and temporal course of attentional and motivational training on excessive drinking.

Two cognitive-motivational variables that help to solidify drinkers' intentions to drink are their alcohol attentional bias and their maladaptive motivation. The Alcohol Attention Control Training Programme (AACTP) was designed to rectify the former, and the Life Enhancement and Advancement Programme (LEAP) was designed to rectify the latter. The present study used a factorial design to compare the individual and combined effects of the 2 interventions on mean weekly drinking and atypical weekly drinking of 148 harmful drinkers (49% males, mean age = 28.

Time-cost analysis of a quantum key distribution system clocked at 100 MHz.

We describe the realization of a quantum key distribution (QKD) system clocked at 100 MHz. The system includes classical postprocessing implemented via software, and is operated over a 12 km standard telecommunication dark fiber in a real-world environment. A time-cost analysis of the sifted, error-corrected, and secret key rates relative to the raw key rate is presented, and the scalability of our implementation with respect to higher secret key rates is discussed.

Comparative transcriptional pathway bioinformatic analysis of dietary restriction, Sir2, p53 and resveratrol life span extension in Drosophila.

A multiple comparison approach using whole genome transcriptional arrays was used to identify genes and pathways involved in calorie restriction/dietary restriction (DR) life span extension in Drosophila. Starting with a gene centric analysis comparing the changes in common between DR and two DR related molecular genetic life span extending manipulations, Sir2 and p53, lead to a molecular confirmation of Sir2 and p53's similarity with DR and the identification of a small set of commonly regulated genes. One of the identified upregulated genes, takeout, known to be involved in feeding and starvation behavior, and to have sequence homology with Juvenile Hormone (JH) binding protein, was shown to directly extend life span when specifically overexpressed.
