Abstract

Purpose

The purpose of this study is to investigate the transport phenomena of smoke flow in a semi-open vertical shaft.

Design/methodology/approach

The large eddy simulation (LES) method was used to model the movement of fire-induced thermal flow in a full-scale vertical shaft. With this model, different fire locations and heat release rates (HRRs) were considered simultaneously.

Findings

It was determined that the burning intensity of the fire is enhanced when the fire attaches to the sidewall, resulting in a larger continuous flame region in the compartment and higher temperatures of the spill plume in the shaft compared to a center fire. In the initial stage of the fire with a small HRR, the buoyancy-driven spill plumes incline toward the side of the shaft opposite the window. Meanwhile, the thermal plumes are also directed away from the center of the shaft by the entrained airflow, but the inclination diminishes as HRR increases. This is because a greater HRR produces higher temperatures, resulting in a stronger buoyancy to drive smoke movement evenly in the shaft. In addition, a dimensionless equation was proposed to predict the rise-time of the smoke plume front in the shaft.

Research limitations/implications

The results need to be verified with experiments.

Practical implications

The results could be applied for design and assessment of semi-open shafts.

Originality/value

This study shows the transport phenomena of smoke flow in a vertical shaft with one open side.

Abstract

Technology-facilitated violence and abuse is a truly global problem. As the diverse perspectives and experiences featured in this book have shown, the deep entanglement between technologies, inequality, marginalization, abuse, and violence require multi-faceted and collaborative responses that exist within and beyond the law. When this chapter was written, society was (and continues to be) facing an unprecedented challenge in COVID-19 – a global pandemic. At the same time, a renewed focus on racist police and civilian violence has occurred following the killings of George Floyd, Ahmaud Arbery, and Breonna Taylor in the United States. As we describe in this chapter, these two major moments are ongoing reminders of the profound social inequalities within our global communities, which are grounded in systemically discriminatory oppressions and their intersections. This chapter draws together some thoughts on technology-facilitated violence and abuse in an era of COVID-19 and antiracist protest. It explores these within the context of the book as a whole, highlighting the importance for improved understanding of, and responses to, technology-facilitated violence and abuse as part of a broader push for social justice.

Abstract

Purpose

The purpose of this paper is to examine whether the impact of persistent racial bias, discrimination and racial violence is facilitated by otherwise well-intentioned individuals who fail to act or intercede. Utilizing the aversive racism framework, the need to move beyond awareness raising to facilitate behavioral changes is discussed. Examining the unique lens provided by the aversive racism framework and existing research, the bystander effect provides important insights on recent acts of racial violence such as the murder of Mr. George Floyd. Some promise is shown by the work on effective bystander behavior training and highlights the need for shared responsibility in preventing the outcomes of racial violence and discrimination to create meaningful and long-lasting social change.

Design/methodology/approach

This paper uses literature based on the aversive racism framework together with the literature on the bystander effect to understand the factors, conditions and consequences for lack of intervention when the victim is African American. This paper also provides evidence and theory-based recommendations for strategies to change passive bystanders into active allies.

Findings

The use of the aversive racism framework provides a powerful lens to help explain the inconsistencies in the bystander effect based on the race of the victim. The implications for intervention models point to the need for behavioral and competency-based approaches that have been shown to provide meaningful change.

Practical implications

Several different approaches to address incidents of racial aggression and violence have been developed in the past. However, given the principles of aversive racism, a unique approach that considers the inconsistencies between self-perceptions and actions is needed. This sets a new agenda for future research and meaningful behavioral intervention programs that seek to equip bystanders to intercede in the future.

Social implications

The need to address and provide effective strategies to reduce the incidence of racial aggression and violence have wide-ranging benefits for individuals, communities and society.

Originality/value

By connecting the aversive racism framework to the bystander effect, the need for different models for developing responsive and active bystanders can be more effectively outlined.

Abstract

Although service-learning increases several important development and learning outcomes in college students (Yorio & Ye, 2012), it is not clear whether service-learning is better preparing these students for their future careers (Gray, Ondaatje, Fricker, & Geschwind, 2000). To better understand the influence of service-learning on student development, an exploration of a leadership service-learning course and an important workplace attribute, Positive Psychological Capital, are theoretically explored.

Abstract

Digital technologies, and the affordances they provide, can shape institutional processes in significant ways. In the last decade, social media and other digital platforms have redefined civic engagement by enabling new ways of connecting, collaborating, and mobilizing. In this article, we examine how technological affordances can both enable and hinder institutional processes through visibilization – which we define as the enactment of technological features to foreground and give voice to particular perspectives and discourses while silencing others. We study such dynamics by examining #SchauHin, an activist campaign initiated in Germany to shine a spotlight on experiences of daily racism. Our findings show how actors and counter-actors differentially leveraged the technological features of two digital platforms to shape the campaign. Our study has implications for understanding the role of digital technologies in institutional processes as well as the interplay between affordances and visibility in efforts to deinstitutionalize discriminatory practices and institutions.

Abstract

Community leaders working in Black communities are faced with countless challenges yet require unique skills for which evidence-based training is often limited or difficult to find. The current study employed a mixed- methods approach using archival data to evaluate a promising and much needed neighborhood leadership program for Black community leaders, the Bunting Neighborhood Leadership Program. The three primary foci of the program were to examine who were selected as fellows, the goals fellows presented with upon entering the program, and the primary outcomes following immediate program completion and follow-up. Nineteen fellows have matriculated through the program, and all completed pre- and post-surveys, and were each contacted about current awards and other leadership successes. Additionally, seven fellows were interviewed about their experiences with and outcomes following the program. Surveys demonstrated important gains in knowledge and skill development for fellows. Following participation, many fellows developed their own organizations, and some secured funding and received awards for their community leadership work. Three key themes emerged from coded interviews, namely (1) characteristics of those who seek a community leadership training, (2) successes in community impact and activities observed among fellows following program completion, and (3) skills-based outcomes for fellows following program completion. The COVID-19 pandemic and killings of Black civilians by police also impacted participants’ responses. The role of blackness in Black community leadership was observed across themes that emerged. Overall, this is a promising community leadership program with important implications for leaders who serve Black communities.

Abstract

In the US, a growing number of organizations and industries are seeking to affirm their commitment to and efforts around diversity, equity, and inclusion (DEI) as recent events have increased attention to social inequities. As health care organizations are considering new ways to incorporate DEI initiatives within their workforce, the anticipated result of these efforts is a reduction in health inequities that have plagued our country for centuries. Unfortunately, there are few frameworks to guide these efforts because few successfully link organizational DEI initiatives with health equity outcomes. The purpose of this chapter is to review existing scholarship and evidence using an organizational lens to examine how health care organizations can advance DEI initiatives in the pursuit of reducing or eliminating health inequities. First, this chapter defines important terms of DEI and health equity in health care. Next, we describe the methods for our narrative review. We propose a model for understanding health care organizational activity and its impact on health inequities based in organizational learning that includes four interrelated parts: intention, action, outcomes, and learning. We summarize the existing scholarship in each of these areas and provide recommendations for enhancing future research. Across the body of knowledge in these areas, disciplinary and other silos may be the biggest barrier to knowledge creation and knowledge transfer. Moving forward, scholars and practitioners should seek to collaborate further in their respective efforts to achieve health equity by creating formalized initiatives with linkages between practice and research communities.
