Abstract
Purpose
This study aims to investigate the material extrusion additive manufacturing (MEAM) deposition parameters for creating viable 3-D printed polyvinylidene fluoride (PVDF) structures with a balanced mix of mechanical and electrical properties.
Design/methodology/approach
Different combinations of deposition conditions are tested, and the influence of these parameters on the final dimensional accuracy, semi-crystalline phase microstructure and effective mechanical strength of MEAM homopolymer PVDF printed parts is experimentally assessed. Considering printed part integrity, appearance, print time and dimensional accuracy, MEAM parameters for PVDF are suggested.
Findings
A range of viable printing parameters for MEAM fabricated PVDF Kynar 740 objects of different heights and in-plane length dimensions was determined. For PVDF structures printed under the suggested conditions, the mechanical response and the microstructure development related to Piezoelectric response are reported.
Originality/value
This research first reports on a range of parameters that have been confirmed to facilitate effective MEAM printing of 3-D PVDF objects, presents effects of the individual parameters and gives the mechanical and microstructure properties of PVDF structures fabricated under the suggested deposition conditions.

Abstract
Little has been written about the use of skill sheets in leadership education and this paper demonstrates how they have been implemented in one specific context. Used in a number of domains (e.g., karate, cardiopulmonary resuscitation) skill sheets are checklists or rubrics that record skill performance. The use of skill sheets in leadership learning and education is a critical step in our efforts to grow as a discipline. Founded in 2015, the Collegiate Leadership Competition has incorporated the use of skill sheets in skill development, assessment of learning, and curriculum design.

Abstract
We conducted a national study of the Collegiate Leadership Competition (CLC), which since inception in 2015, has included over 75 higher education institutions. The CLC brings students together in collaborative institution-based teams to compete with other teams in competitions to achieve goals and practice effective leadership skills. Our goal was to assess leadership capacity growth over the course of a four-month team practice period through the daylong inter-team competition and evaluate participant leadership assessed several months later. Results suggested students made significant and sustainable gains in leader-self-efficacy and short-term gains in leadership skill and motivation to lead. Our results also indicated the team’s coach played a significant role in student leadership development.
Leadership development programs for students in educational settings are proliferating in number and design. Curricular programs range from academic minors and certificates to doctoral programs in a variety of academic homes (e.g., education, business, healthcare). Co-curricular programs often take the form of drop-in workshops, day-long experiences, alternative spring breaks, service-learning trips, and other programs housed in student affairs and administrative offices (Guthrie & Jenkins, 2018). Moreover, the number of programs has steadily increased over the last 15 years from just under 1,000 in 2006 (Brungardt, et al., 2006) to more than 2,000 (ILA Program Directory, 2021). And while there is some commonality among the approach of these leadership programs in terms of content and delivery (see Harvey & Jenkins, 2014), vast differences exist in the structure and learning goals of student leadership programs compared to other social science disciplines. A potentially fruitful area in which to explore its effectiveness in supporting leadership development is the environment of competitive teams, where individuals work together as a group to compete against other teams. The purpose of our research was to investigate the degree to which such a competitive environment might support or detract from student leadership group, employing a potentially effective example of a formal program that utilizes the innovative approach of team competitions to motivate learning (the CLC).

Abstract
Purpose
Using a unique sample of about 563,000 competitively bid municipal revenue bonds with financial advisors issued during the period 1998–2012, the purpose of this paper is to examine the role and influence of financial advisor quality in the municipal bond market.
Design/methodology/approach
The authors use a sample of about 563,000 competitively bid municipal revenue bonds with financial advisors issued during the period 1998–2012. The authors estimate a selection model where the authors identify the factors leading to the selection of a high-quality financial advisor. The authors then, using the inverse mills ratio from the first regression, estimate the association of high-quality advisor (and other factors) with the cost of borrowing.
Findings
The results suggest that high-quality financial advisors provide a credible signal to market participants about issue and issuer quality. This signal translates to a greater number of bids for issues that use high-quality financial advisors, resulting in improved liquidity and lower borrowing costs for these issues. The results also show that the beneficial effects obtained by using higher quality financial advisors are prevalent across all categories of issues such as for refunding and non-refunding issues, and for both insured and non-insured issues. The benefits are also generally observed for issues of most size categories. The results also suggest that the passage of the Dodd–Frank Act requiring mandatory registration of financial advisors and enhanced scrutiny has only increased the benefits to issuers from using higher quality financial advisors.
Originality/value
This paper differs from previous research in several important ways. First, the study is, to the authors’ knowledge, the first study that explores the relationship between financial advisor quality and liquidity in the municipal sector. The authors show using higher quality financial advisors enhances liquidity for the issues by attracting a significantly large number of bids. Second, the sample is exclusively comprised of competitively bid revenue issues all of which rely on financial advisors. This enables us to examine more unambiguously the influence of financial advisor quality, without the confounding effects of issues without financial advisors. Third, time coverage (1998–2012) and size of the sample (roughly 563,000 bond issues) enables us to conduct varied sub-sample analyses with greater power since the resulting sub-sample partitions themselves are of very large size. This provides better and additional insights into the role of financial advisor quality. The more current data when compared to prior research enables us to examine the impact of financial advisor quality inter-temporally with special attention devoted to the period after passage of the Dodd–Frank Act.

Abstract
Purpose
This paper aims to focus on The Pillars of Peer Support initiative, an ongoing project to examine and develop the principles of peer support services. These services are differentiated from peer support and define the parameters of a certified workforce that promotes recovery and fosters wellbeing. This process is based upon the lived experience of the peer support specialist.
Design/methodology/approach
A review of the literature indicates that a range of models and activities for peer support services have been developed, and established outcomes for these services are emerging. Since Medicaid has defined peer support services as reimbursable, the workforce has continued to expand. The Pillars of Peer Support initiative is designed to provide a standard set of principles to guide states in their work with Medicaid, and others in the development of this workforce.
Findings
The results of three Pillars of Peer Support summits are presented. This includes the 25 Pillars that have been developed and their role and use in state funded and other services. Additional findings support the process through which states and others can build these resources. A statement of how Peer Support Services fit within an essential health benefits package is also included.
Originality/value
The workforce of certified peer specialists is rapidly expanding. Their role in providing peer support services is identified, and principles to guide their professional roles are presented. This will help guide the field in the development and deployment of this important component of the healthcare delivery system.

Abstract
The purpose of this study was to examine the overall quality of care being delivered, and to determine if gender, race, age, and education level affected the quality of care being delivered in inpatient mental health programmes. To accomplish this objective, the study utilised patient survey data collected in 2006. Measures were selected from the survey that best matched the Institute of Medicine's (IOM) six dimensions of quality framework: safe, effective, timely, efficient, equitable and patient‐centred. This study may be a useful tool to guide the assessment of clinical programmes and the role of leadership in this process.

Abstract
Using the philosophical lenses of revisionist ontology and the politics of personhood, this paper explores the notion of Black Founders of the United States. I introduce the concept critical intellectual agency to argue that Black Founders brought unique contributions to the American experience. Their efforts were twofold. First, Black Founders established separate Black institutions that would become staples in Black communities after emancipation. Second, Black Founders challenged the supposed egalitarian beliefs of White Founders through media outlets. To illustrate, I focus on one Black Founder, Benjamin Banneker and his letter to Thomas Jefferson to illustrate how Black Founders philosophically responded and challenged White Founders prejudicial beliefs about Blackness. This paper seeks to challenge social studies teachers’ curricular and pedagogical approaches to Black Americans during the colonial period by providing a heuristics and language to explore the voices of Black Americans in U.S. history.

Abstract
Outlines some of the areas in machine vision system solution which have seen the most significant advances as a result of technology enhancement and particularly the rapid development in semiconductor technology. Looks at the background of machine vision development and improvements brought about by modern technology, covering advances in vision algorithms, “warp engines” used in combination with an application specific integrated circuit [ASIC], improvements in human interface; and optical character recognition. Concludes that the trend now is for general purpose vision processing systems to provide greater capability, at greater throughput speed, without significantly increasing the cost of the system which means that they are now part of the original process design to inspect critical stages of manufacture.
