Abstract

Purpose

Sexual violence has a profound impact on victim-survivors across the world, and these consequences extend beyond cultural boundaries. While the mental health consequences are well established across the Western world, less is known about the impact on victims in China. This is somewhat surprising given the size of the population. The purpose of this study is, therefore, to provide a rapid review of existing studies that have investigated mental health outcomes for victim-survivors of sexual violence in China.

Design/methodology/approach

In this brief review paper, the authors conduct and provide a thematic synthesis and scrutiny of evidence surrounding two rarely reported yet common types of sexual violence experienced by victim-survivors in China, intimate partner sexual violence and childhood sexual abuse, examining the impact on survivor mental health.

Findings

Taken together, studies show wide-ranging and severe psychological consequences, including depression, post-traumatic stress disorder, personality and identity difficulties and suicidal attempts and ideations.

Originality/value

The unique cultural traditions that appear to exacerbate victim-survivor abuse experiences, non-disclosure practices and mental health outcomes are also identified and considered with future interventions in mind.

Abstract

Purpose

The purpose of this paper is to reveal the influence of dimples on the tribological properties of the “washers-cage-rollers” system of rolling element bearing (REB) under starved lubrication.

Design/methodology/approach

A fiber laser marking system was used to prepare dimples patterns on the raceways of the shaft washers of cylindrical roller thrust bearings (CRTBs). The friction and wear properties of dimples textured CRTBs with different diameter of dimples (200 µm, 250 µm, 300 µm) and depth of dimples (4 µm, 8 µm, 12 µm) were researched through a vertical universal wear test rig using a customized tribo-pair under starved lubrication. The surface stresses and the influence mechanism of dimple units on the tribological behavior of REBs were also compared and discussed.

Findings

Although the surface stresses on the raceways of dimples textured bearings are significantly higher than that of the smooth group, the coefficients of friction and wear losses of them are all reduced under starved lubrication. When the effective volume of dimples is between 1.13 and 2.25 and the depth of dimples is smaller than 12 µm, the tribological properties of dimples textured CRTBs are significantly improved. In this work, when the diameter of dimples is 250 µm, and the depth of dimples is 8 µm, the textured bearings can provide the excellent friction-reduction ability and outstanding wear resistance.

Originality/value

This work is a valuable reference for the raceway design and optimization of REBs.
