Abstract
Purpose
This paper aims to examine tensions around play, performance and artmaking as becoming in the mix of expected and taken-for-granted discourses implicit in an after-school ceramics makerspace (Perry and Medina, 2011). The authors look closely at one adolescent girl’s embodied performance to see how it ruptures the scripts for compliant bodies in the after-school program. While these performances take place out-of-school and in an arts studio, the tensions and explorations also resonate with broader issues around student embodied, performative and becomings that run counter to normalized school expectations.
Design/methodology/approach
A contemporary approach to nexus analysis (Medina and Wohlwend, 2014; Wohlwend, 2021) unpacked two critical performative encounters (Medina and Perry, 2011) using concepts of historical bodies (Scollon and Scollon, 2004) informed by sociomaterial thing-power (Bennett, 2010).
Findings
Playing while painting pottery collides and converges with the tacitly desired and expected ways of embodying student in this after-school artspace. Emily’s outer-space alien persona ruptured expected discourses when her historical body and embodied performances threatened other children. While her embodied performances facilitated her becoming a fully present participant in the studio, she fractured the line between play and reality in violent ways.
Originality/value
As literacy researchers, the authors are in a moment of reckoning where student embodied performances and historical bodies can collide with all-too-real violent threats in daily lives and community locations. Situating these performances in the nexus of embodied literacies, unsanctioned play and thing-power can help educators respond to these moments as ruptures of tacit expectations for girlhoods in school-like spaces.

Abstract
Many jurisdictions fine illegal cartels using penalty guidelines that presume an arbitrary 10% overcharge. This article surveys more than 700 published economic studies and judicial decisions that contain 2,041 quantitative estimates of overcharges of hard-core cartels. The primary findings are: (1) the median average long-run overcharge for all types of cartels over all time periods is 23.0%; (2) the mean average is at least 49%; (3) overcharges reached their zenith in 1891–1945 and have trended downward ever since; (4) 6% of the cartel episodes are zero; (5) median overcharges of international-membership cartels are 38% higher than those of domestic cartels; (6) convicted cartels are on average 19% more effective at raising prices as unpunished cartels; (7) bid-rigging conduct displays 25% lower markups than price-fixing cartels; (8) contemporary cartels targeted by class actions have higher overcharges; and (9) when cartels operate at peak effectiveness, price changes are 60–80% higher than the whole episode. Historical penalty guidelines aimed at optimally deterring cartels are likely to be too low.

Abstract
The body of literature in the field now commonly known as the “quality of working life” (QWL) has grown steadily over a period in which the industrialised nations have increasingly come to question the role and status of human beings in the modern technological environment. In recent years concern with the nature of work, its impact upon people, and their attitudes towards it, seem to have sharpened. Investigation of, and experimentation with, the qualitative aspects of working life—its ability to confer self‐fulfilment directly, for example, as opposed to being a means of acquiring goods—has gained momentum under the influence of a unique set of economic, social, political and technological factors. The outpouring of books, reports and articles from a wide variety of sources has, not surprisingly, grown apace.

Abstract
Purpose
The purpose of this paper is to present a hybrid manufacturing system that integrates stereolithography (SL) and direct print (DP) technologies to fabricate three‐dimensional (3D) structures with embedded electronic circuits. A detailed process was developed that enables fabrication of monolithic 3D packages with electronics without removal from the hybrid SL/DP machine during the process. Successful devices are demonstrated consisting of simple 555 timer circuits designed and fabricated in 2D (single layer of routing) and 3D (multiple layers of routing and component placement).
Design/methodology/approach
A hybrid SL/DP system was designed and developed using a 3D Systems SL 250/50 machine and an nScrypt micro‐dispensing pump integrated within the SL machine through orthogonally‐aligned linear translation stages. A corresponding manufacturing process was also developed using this system to fabricate 2D and 3D monolithic structures with embedded electronic circuits. The process involved part design, process planning, integrated manufacturing (including multiple starts and stops of both SL and DP and multiple intermediate processes), and post‐processing. SL provided substrate/mechanical structure manufacturing while interconnections were achieved using DP of conductive inks. Simple functional demonstrations involving 2D and 3D circuit designs were accomplished.
Findings
The 3D micro‐dispensing DP system provided control over conductive trace deposition and combined with the manufacturing flexibility of the SL machine enabled the fabrication of monolithic 3D electronic structures. To fabricate a 3D electronic device within the hybrid SL/DP machine, a process was developed that required multiple starts and stops of the SL process, removal of uncured resin from the SL substrate, insertion of active and passive electronic components, and DP and laser curing of the conductive traces. Using this process, the hybrid SL/DP technology was capable of successfully fabricating, without removal from the machine during fabrication, functional 2D and 3D 555 timer circuits packaged within SL substrates.
Research limitations/implications
Results indicated that fabrication of 3D embedded electronic systems is possible using the hybrid SL/DP machine. A complete manufacturing process was developed to fabricate complex, monolithic 3D structures with electronics in a single set‐up, advancing the capabilities of additive manufacturing (AM) technologies. Although the process does not require removal of the structure from the machine during fabrication, many of the current sub‐processes are manual. As a result, further research and development on automation and optimization of many of the sub‐processes are required to enhance the overall manufacturing process.
Practical implications
A new methodology is presented for manufacturing non‐traditional electronic systems in arbitrary form, while achieving miniaturization and enabling rugged structure. Advanced applications are demonstrated using a semi‐automated approach to SL/DP integration. Opportunities exist to fully automate the hybrid SL/DP machine and optimize the manufacturing process for enhancing the commercial appeal for fabricating complex systems.
Originality/value
This work broadly demonstrates what can be achieved by integrating multiple AM technologies together for fabricating unique devices and more specifically demonstrates a hybrid SL/DP machine that can produce 3D monolithic structures with embedded electronics and printed interconnects.

Abstract
Life studies are a rich source for further research on the role of the Afro‐American woman in society. They are especially useful to gain a better understanding of the Afro‐American experience and to show the joys, sorrows, needs, and ideals of the Afro‐American woman as she struggles from day to day.

Abstract
Incoming first-year college students (N = 4,292) were surveyed regarding attitudes and beliefs about leadership. Students’ opinions about their leadership ability were high and were related to having an outgoing personality, as well as the number of high school activities in which they had been involved. In addition, students’ understanding of leadership was largely hierarchical and unsophisticated. Gender was strongly related to beliefs about leadership, with males indicating a stronger belief in hierarchical leadership, and females indicating a stronger belief in systemic leadership. The results indicated men and women are most likely to be anchored in Komives et al.’s (2009) Stages 2 and 3 whereas women also show some characteristics of Stage 4. It was argued these results support a modular approach to leadership development in which students acquire credits toward a certificate in leadership and where some components of the training activities involve separating the genders.

Abstract
Bridge programs constitute institutionalized interventions to provide equitable educational opportunities for low-income, first-generation, and disadvantaged traditional undergraduate students (Gullatt & Jan, 2003). These are typically pre-college transition programs that serve to facilitate college access and readiness. This chapter discusses the role of bridge programs at American colleges and universities and the recommends integration of the Dynamic Student Development Metatheodel (DSDM) student success model (Frederick, Sasso, & Barratt, 2015). This chapter outlines the typology of bridge programs at the federal, state, and campus levels and highlights the target populations of these programs. Evaluation and outcomes regarding the efficacy of these programs are also highlighted. Implications and considerations for practice are provided integrating specific constructs from the DSDM to inform the further development of bridge programs to increase student development.

Abstract
The Bureau of Economics in the Federal Trade Commission has a three-part role in the Agency and the strength of its functions changed over time depending on the preferences and ideology of the FTC’s leaders, developments in the field of economics, and the tenor of the times. The over-riding current role is to provide well considered, unbiased economic advice regarding antitrust and consumer protection law enforcement cases to the legal staff and the Commission. The second role, which long ago was primary, is to provide reports on investigations of various industries to the public and public officials. This role was more recently called research or “policy R&D”. A third role is to advocate for competition and markets both domestically and internationally. As a practical matter, the provision of economic advice to the FTC and to the legal staff has required that the economists wear “two hats,” helping the legal staff investigate cases and provide evidence to support law enforcement cases while also providing advice to the legal bureaus and to the Commission on which cases to pursue (thus providing “a second set of eyes” to evaluate cases). There is sometimes a tension in those functions because building a case is not the same as evaluating a case. Economists and the Bureau of Economics have provided such services to the FTC for over 100 years proving that a sub-organization can survive while playing roles that sometimes conflict. Such a life is not, however, always easy or fun.
