Factors in the cycle of violence: Gender rigidity and emotional constriction.

Abstract: A sample of 595 men were administered self-report assessments of childhood sexual and physical abuse, perpetration history, gender rigidity and emotional constriction. Including noncontact forms of sexual abuse, 11% of the men reported sexual abuse alone, 17% reported physical abuse alone, and 17% reported both sexual and physical abuse. Of the 257 men in the sample who reported some form of childhood abuse, 38% reported some form of perpetration themselves, either sexual or physical; of the 126 perpetrators, 70% reported having been abused in childhood. Thus, most perpetrators were abused, but most abused men did not perpetrate. Both sexually and physically abused men who perpetrated manifested significantly more gender rigidity and emotional constriction than abused nonperpetrators. Men who reported abuse but not perpetration demonstrated significantly less gender rigidity, less homophobia and less emotional constriction than nonabused men.

The Relationship Between Food Security, Housing Stability, and School Performance Among College Students in an Urban University:

Abstract: Although younger populations, such as emerging adults, have been shown to be particularly susceptible to food insecurity and housing instability, the current research is predominantly devoid of lit...

The critical ingredient: Caring youth‐staff relationships in after‐school settings

Abstract: After-school settings are interpersonal in nature, and the quality of the relationships that are forged can directly influence youths' attendance decisions and the developmental benefits they derive. Programs should more effectively capitalize on this potential for caring adult-staff relationships.

An optimality proof of the LRU-K page replacement algorithm

Abstract: This paper analyzes a recently published algorithm for page replacement in hierarchical paged memory systems [O'Neil et al. 1993]. The algorithm is called the LRU-K method, and reduces to the well-known LRU (Least Recently Used) method for K = 1. Previous work [O'Neil et al. 1993; Weikum et al. 1994; Johnson and Shasha 1994] has shown the effectiveness for K > 1 by simulation, especially in the most common case of K = 2. The basic idea in LRU-K is to keep track of the times of the last K references to memory pages, and to use this statistical information to rank-order the pages as to their expected future behavior. Based on this the page replacement policy decision is made: which memory-resident page to replace when a newly accessed page must be read into memory. In the current paper, we prove, under the assumptions of the independent reference model, that LRU-K is optimal. Specifically we show: given the times of the (up to) K most recent references to each disk page, no other algorithm A making decisions to keep pages in a memory buffer holding n - 1 pages based on this infomation can improve on the expected number of I/Os to access pages over the LRU-K algorithm using a memory buffer holding n pages. The proof uses the Bayesian formula to relate the space of actual page probabilities of the model to the space of observable page numbers on which the replacement decision is acutally made.

Universal far-from-equilibrium Dynamics of a Holographic Superconductor

Abstract: In strongly coupled systems lacking long-lived quasiparticles, conventional methods are inadequate to study the dynamics of phase transitions. Here, the authors use holographic duality to investigate the superconducting transition and show that critical dynamics and formation of topological defects are universal.
