Abstract

Purpose

This paper aims to investigate the deposited structure and mechanical performance of printed materials obtained during initial development of the Big Area Additive Manufacturing (BAAM) system at Oak Ridge National Laboratory. Issues unique to large-scale polymer deposition are identified and presented to reduce the learning curve for the development of similar systems.

Design/methodology/approach

Although the BAAM’s individual extruded bead is 10-20× larger (∼9 mm) than the typical small-scale systems, the overall characteristics of the deposited material are very similar. This study relates the structure of BAAM materials to the material composition, deposition parameters and resulting mechanical performance.

Findings

Materials investigated during initial trials are suitable for stiffness-limited applications. The strength of printed materials can be significantly reduced by voids and imperfect fusion between layers. Deposited material was found to have voids between adjacent beads and micro-porosity within a given bead. Failure generally occurs at interfaces between adjacent beads and successive layers, indicating imperfect contact area and polymer fusion.

Practical implications

The incorporation of second-phase reinforcement in printed materials can significantly improve stiffness but can result in notable anisotropy that needs to be accounted for in the design of BAAM-printed structures.

Originality/value

This initial evaluation of BAAM-deposited structures and mechanical performance will guide the current research effort for improving interlaminar strength and process control.

Abstract

Purpose

The study of women business founders provides an opportunity to determine their unique leadership characteristics. Starting a business may be a way for women business owners to be authentic and create more people-centered businesses. Servant leadership’s gender integrative attributes where both agentic and communal behaviors are valued may be more congruent and reflective of the leadership behaviors of women entrepreneurs. Recently, the motivation of compassionate love was theorized to be an antecedent to servant leadership and, it is argued, exists in conjunction with authenticity. Thus, the purpose of this study is to investigate compassionate love, authenticity and servant leadership and determine whether they exist in the behaviors of founding female business owners.

Design/methodology/approach

This qualitative research study used summative content analysis of telephone interviews conducted with 12 women business owners of professional service firms in four US states to determine whether these women’s motivations, traits and behaviors were consistent with the compassionate love servant leadership model and whether authenticity was the cornerstone of servant leadership.

Findings

The analyses found that these women revealed a strong authenticity orientation as they enacted a compassionate love servant leadership style within their businesses. Themes that emerged from the study were agency, calling, humility, trust and respect, self-development, stewardship, authenticity and providing direction. The study revealed support for some of the characteristics associated with compassionate love servant leadership and two characteristics which were unique to this study.

Research limitations/implications

As a qualitative study of 12 individuals, these findings may not be generalizable beyond the four US states of professional service enterprises of women business founders. Future research should test the full servant leadership model of women business owners on a larger group of business founders and the sub-themes where little support exists.

Practical implications

The more gender integrative style of compassionate love servant leadership may be beneficial for women owners to employ as business leaders.

Originality/value

This research revealed support for a variation of compassionate love servant leadership model. The resulting servant leadership model herein was a mixture of agentic and communal leadership motivations, traits and behaviors useful to women business founders. Behaviors of authenticity were found to complement compassionate love. These women were able to extend the boundaries of what it means to be a leader and incorporate behaviors associated with both their gender and leadership roles, thus expanding their ability to successfully empower and equip themselves to navigate barriers unique to women leaders.

Abstract

Purpose

The purpose of this paper is to present a novel methodology to produce a large boat hull with a foam additive manufacturing (FAM) process. To respond to shipping market needs, this new process is being developed. FAM technology is a conventional three-dimensional (3D) printing process whereby layers are deposited onto a high-pressure head mounted on a six-axis robotic arm. Traditionally, molds and masters are made with computer numerical control (CNC) machining or finished by hand. Handcrafting the molds is obviously time-consuming and labor-intensive, but even CNC machining can be challenging for parts with complex geometries and tight deadlines.

Design/methodology/approach

The proposed FAM technology focuses on the masters and molds, that are directly produced by 3D printing. This paper describes an additive manufacturing technology through which the operator can create a large part and its tools using the capacities of this new FAM technology.

Findings

The study shows a comparison carried out between the traditional manufacturing process and the additive manufacturing process, which is illustrated through an industrial case of application in the manufacturing industry. This work details the application of FAM technology to fabricate a 2.5 m boat hull mold and the results show the time and cost savings of FAM in the fabrication of large molds.

Originality/value

Finally, the advantages and drawbacks of the FAM technology are then discussed and novel features such as monitoring system and control to improve the accuracy of partly printed are highlighted.

Abstract

Purpose

The purpose of this study is to examine how the search for transitional services has been characterized as a challenging experience for autistic youth and their families. Transitional services are reported to be inconsistent and do not address the range of needs that autistic individuals have.

Design/methodology/approach

In this study, qualitative interviews were conducted with autistic individuals (n = 31), their parents/caregivers (n = 23) and transition-based service providers (n = 10).

Findings

Findings invite capacity building across sectors, including working with both the autistic individual and their caregiver, and ensuring targeted services commensurate with individual needs related to autism and ancillary challenges. Implications and recommendations for service and system advancement are offered.

Practical implications

Current services were reportedly insufficient in meeting the needs of autistic individuals as they transitioned into adulthood. Service areas needing to be bolstered include daily life, community engagement and employment. Capacity building and enhanced training are required. Information and communication strategies require advancement.

Social implications

A more responsive system is required, which involves support from many societal sectors (e.g. health, mental health, advanced education, social services, industry, housing and justice) over the lifespan. Policy adjustments and organizational mandates need to be reviewed to better consider the needs of transitioning autistic youth and allocate resources accordingly. Partnerships across stakeholder groups are needed.

Originality/value

This study provides details on a known but not well understood issue of transition to adulthood for autistic adults. This study is unique in providing first-hand data from transitioning autistic adults, with corroborating data from families and service providers.

Abstract

A number of international relations' mid-level theories about violence are inadequate to the task of explaining societal and group violence. Many of these theories, for example, confuse causality with correlation, or breakdown and then cannot explain why they fail. Building upon the theories of criminologist Lonnie Athens, both in their particulars and in their spirit of practical solution rather than entrenched debate, this article considers whether those theories of individual violence are suitable for extrapolation to the societal level. It explores some problems with the current theories in international relations, and reviews the theoretical foundations offered by Athens and some others, who have also laid strong groundwork for scaling Athens' theories to the societal level by considering their applications to communities. A number of those theories, although based upon analyses of individual dangerous violent criminals, lend themselves particularly well to groups and communities, suggesting strong suitability of scaling to these levels, and to the societal one as well. Also considering critiques of Athens' and Rhodes' work, this article ultimately argues that Athens' theories of violence, and those building upon them, constitute a strong foundation for theories of violence in international relations that relate to the societal scale.

Abstract

I have been asked by Professor Lonnie Athens to shed light upon those parts of my academic career that may be of interest to sociologists working within the tradition of symbolic interactionism. With this in mind, the present essay offers an account of how I became a scholar whose main focus has for many years been the philosophy and social psychology of George Herbert Mead (1863–1931).

Abstract

Celeste West: As publisher of Down There Press, your nine titles are famous, even notorious, for being the most “out there” sex titles this side of pornography. Yet you are an ardent feminist—in fact, one of the most successful and respected women in feminist publishing. A lot of people would feel that combining pleasure and politics makes for strange bedfellows, so to speak. How did this come about?

Abstract

Million Dollar Baby displays a contrived, provocative, and dramatic sequence of events that culminates in the death of a paralyzed woman, Maggie (played by Hilary Swank), a boxer by trade, who became a quadriplegic after her opponent “cold-cocked” her during a championship fight. The cheap shot caused her to fall on her wooden stool and break her neck. She calls upon her trainer, Frankie (played by Clint Eastwood), to kill her through an injection of adrenaline. Maggie claims that she has already died in that she can never be a boxer, which represents the only self she knows and loves. Ignoring Frankie's efforts to dissuade her, Maggie evokes a story from their shared past. The story, first told in a diner in which Maggie and Frankie had stopped to eat, described her own father's decision to kill the family dog. She iterates the story from her hospital bed and begs Frankie to do what her dad (to whom Maggie refers as “daddy”) did to the dog. In effect, she asks Frankie to assist her suicide, as she defines herself as useless beyond any reason to live.
