Evaluation of the Possibilities of Processing High-Alloy Corrosion-Resistant Steels during Grinding Operations

The issues of processing high-alloy corrosion-resistant steels by the method of centerless cylindrical grinding are considered in the article. Experimental data on changes in the parameters of roughness and hardness of a workpiece depending on the depth of cut, the speed and the design features of a control wheel are presented. The change in the microhardness of a part depending on the depth of cut is analyzed. Much attention is paid to the study of thermal stress of the grinding process. Images of temperature changes in the cutting zone depending on the grinding wheel characteristics are shown. Conclusions in the form of practical recommendations for improving high-alloy steel processing by the method of centerless grinding are formulated on the basis of the results obtained.

Understanding the economics of abuse: an assessment of the economic abuse definition within the Domestic Abuse Bill

The term ‘economic abuse’ was first introduced into discourse when it was identified as a tactic used by perpetrators within the Duluth Power and Control Wheel. Yet it is only recently that researchers have turned their attention to defining and understanding it. This article draws on a review of the global and UK specific academic research literature to assess the suitability of the definition of economic abuse put forward within the Westminster government’s Domestic Abuse Bill. It recommends that a) the term ‘any behaviour’ within the definition is understood to include controlling tactics which sit under the constructs of economic restriction, exploitation and/or sabotage, b) the definition recognises perpetrators will also prevent a partner from using/maintaining goods or services and, c) attention is given to the suggestion that single incidents of economic abuse would not fall under this definition. While the focus of this article is on Westminster policy in the UK, the case for ‘naming’ and defining economic abuse in statute has wider resonance, not least because it provides a framework within which to report on prevalence, hold perpetrators accountable and for services (statutory and voluntary) to respond.<br /><br />Key messages<br /><ul><li>This article critically assesses the definition of economic abuse within the Westminster government’s Domestic Abuse Bill and argues that there is ‘room for improvement’.</li><br /><li>The term ‘any behaviour’ within the definition of economic abuse should be understood to include controlling tactics which sit under the constructs of economic restriction, exploitation and/or sabotage.</li><br /><li>A clear understanding of the constructs of economic abuse is vital if the Westminster government is to report on prevalence (as required by the Istanbul Convention) and frontline practitioners are to understand and meet the complex needs of victim-survivors.</li></ul>

“When Her Visa Expired, the Family Refused to Renew It,” Intersections of Human Trafficking and Domestic Violence: Qualitative Document Analysis of Case Examples from a Major Midwest City

This study aimed to further understand typologies of trafficking that occur in the home, by an individual’s intimate partner (IP) or family members and this overlap with extant knowledge on perpetrator manipulation via the Power and Control Wheel. Inductive and deductive techniques were used to analyze secondary data from a federally funded anti-trafficking program in a Midwest metropolitan area recorded between 2008 and 2017. Cases were included if there was indication of sex or labor exploitation initiated by an IP, family member, or other in the domestic setting via elements of abuse; 59 cases of 213 met this criteria. Most cases included the IP as the trafficker, followed by family members, then others in the domestic setting. Abuse was more commonly used than the threat of abuse. From the Power and Control Wheel, the most frequent types of abuse were using privilege, physical abuse, economic abuse, isolation, and sexual abuse. Case typologies included: those with elements of sex trafficking, specifically forced commercial sex by an IP or family member; those with elements of labor trafficking such as domestic servitude (with or without childcare provision abuse), exploitation in a family business by an IP or family member, or work environments by family and non-family; those with elements of sex and labor trafficking included servile partnerships and forced marriage. Trafficking exploitation by an IP, family member, or in the domestic setting is not uncommon. Intimate relationships with a trafficker, psychological coercion, and threats may reduce reporting of abuse, subsequent provision of services, and result in misclassification as victims of IP violence. This study sheds light on various typologies of trafficking and exploitation in the domestic setting, further expanding the anti-trafficking movement’s evidence base for intervention and prevention and adding complexity and nuance to the pathways to trafficking exploitation.

Beyond the Power and Control Wheel: how abusive men manipulate mobile phone technologies to facilitate coercive control

Mobile phone ownership has become almost universal, with smartphones the most popular consumer electronics device. While the role of technologies and digital media in the domestic abuse of women is gaining international attention, specific information regarding how mobile phones, and their various ‘apps’, may assist perpetrators in the coercive control of their current or former partners is still a relatively unexplored area in the research literature. This study with women survivors was able to identify that perpetrators use mobile phones in ways that go beyond the traditional tactics of abuse identified through the globally used feminist theorisation of the Power and Control Wheel (developed by the Duluth Domestic Abuse Intervention Programme). The portability and diverse capabilities of mobile phones have been manipulated by abusive men to develop strategies of ‘agile technological surveillance’, which allow them to track and monitor their partners in various ways ‘on the go’ and irrespective of physical proximity. An adaptation of the Power and Control Wheel has been developed and licensed to account for these new opportunities for surveillance, manipulation and control. Proposals are made for integrating this revised framework into professional practice to inform the assessment and management of risk in abusive relationships.

Womanism and Domestic Violence

Domestic violence is a public health problem shown to inflict severe mental and physical injury on millions of individuals and has considerable social costs. Absent from the literature is an examination of womanism ideologies, which provide a greater understanding of the full praxis that black women who experience domestic violence engage. Drawing from initial conceptualizations of womanism and later contributions of Africana womanism, this article brings into focus pervasive acts of violence perpetrated against black women, their racial loyalty to protect black men, and the limitations of existing domestic violence models and interventions. This entry addresses how these three interconnected areas are treated within the conceptual framework of womanism. An overview of violence against black women reveals the historical and contemporary forms of knowledge and praxis that have sought to overcome the social problem of intimate partner abuse, including the social construction of controlling images and the Power and Control Wheel (The Duluth Model). This entry also examines the prevalence of violence perpetrated against black women and compounding factors. In addition, this author considers the Violence Against Women Act and its consequences on laws and policies that affect the race, gender, and class experiences of black women coping with domestic violence. Also analyzed is the quintessential role of demographics, the culture of domestic violence, and international debates about womanism, including how black women intellectuals are prioritizing race-empowerment perspectives and a reference point to articulate healthy black relationships are prioritized. The article also reviews social work practice with black women victims/survivors of domestic violence and their families.

A Study on Roughness of Workpiece Surface When Centreless Grinding of SAE1045 Steel

This paper presents a study of roughness of surface of centreless grinding workpiece with horizontal feed. The testing material used in this study is SAE1045 steel. This study was conducted with three main contents. The first one is an experimental study that determines the impact of dressing feed rate, depth of dressing, horizontal feed rate and the velocity of control wheel to roughness of workpiece surface. The second one is to build the roughness model of workpiece surface by the response surface method. The third one is to use the roughness model to predict the surface roughness, and compare with roughness value when testing. The issues that need to be carried out in subsequent studies have also been mentioned in this paper.

Nonconsensual Porn as a Form of Intimate Partner Violence: Using the Power and Control Wheel to Understand Nonconsensual Porn Perpetration in Intimate Relationships

Over the last decade, nonconsensual porn (NCP), or the sharing of sexually explicit material without a person’s consent, has become a growing problem with potentially far-reaching adverse consequences for victims. The purpose of this article is to propose and consider a framework for advancing the field’s understanding of NCP within the context of intimate relationships including situating NCP relative to other forms of relational abuse. Specifically, we examined the extent to which NCP in intimate partner relationships was perpetrated using tactics from the Power and Control Wheel through a summative content analysis of U.S. news stories on NCP from 2012 to 2017. This analysis established that NCP has been perpetrated using all eight of the abuse metatactics in the Power and Control Wheel, with the three most common being emotional abuse, coercion and threats, and denial/blame/minimization. Treating NCP in relationships as a potential form of partner violence provides a basis on which to understand the etiology, manifestation, motives, and impact of this form of abuse and informs practitioners’ ability to design prevention efforts and engage a trauma-informed response to survivors.
