Choral music and public singing was once regarded as an acceptable and popular socio-cultural activity for males. Through centuries of gradual socio-cultural change male choral participation and public singing became marginalized in the United States. During the past century (1914-2014), adolescent female singers have typically outnumbered male singers at the secondary level. The numerical imbalance between adolescent males and females in secondary choral classrooms is a symptom of a more complicated problem that involves a complex web of perceived physiological, psycho-socio, and schooling barriers. If no single perceived barrier accounted for the lack of male choral participation our collaborative group surmised that no one-dimensional approach would likely succeed in increasing male choral participation. Collaborative inquiry provided a more holistic approach to dealing with the lack of male choral singers at the middle and high school levels and answers questions not adequately addressed by other forms of research. The purpose of this collaborative inquiry was to cooperate with five vocal music practitioners, at two different district sites in the Midwest region of the United States. Our collaborative inquiry group set two broad goals for this study: (1) to implement specific action-oriented strategies in our choral classrooms with the intention of encouraging male choral participation at the middle and high school levels; and (2) to learn more about collaborative inquiry as a research approach and adult learning strategy. My collaborators and I realized a very delicate ecosystem is required for adolescent males and females to engage in singing activities at school. The findings of this inquiry suggest that action-oriented strategies (e.g., single-sex choirs, recruitment and retention activities, same-sex peer role modeling and mentoring) can be implemented in the choral classroom to mitigate the perceived physiological, psycho-socio, and schooling barriers and encourage male choral participation at the secondary level. Our inquiry group found that external issues beyond the control of the choral practitioners (e.g., changes in administration, school schedules, class requirements, and elective choices) were difficult to address. While the goal of encouraging male choral participation continues to be an important issue for everyone that was involved in this inquiry, we came to realize the most important outcome was recognizing the power of collaboration.

According to Sundstrom (1999), performing teams conduct “complex, time-limited engagements with audiences in performance events for which teams maintain specialized, collective skill” (p. 20). Musical ensembles have been included in team research on orchestral leadership, yet as a performing team, the internal connections between musicians have not been studied. The handbell ensemble operates as a performing team while sustaining a prominent degree of interdependence. It is generally unknown how musical performing teams such as the handbell ensemble function and learn interdependently. Using Salas et al.’s (2005) Big Five theory of teamwork as a theoretical lens, I conducted a case study of a community handbell ensemble to understand: (a) how interdependent team interactions of team leadership, mutual performance monitoring, backup behavior, adaptability, and/or team orientation contribute to the function of and learning within this handbell ensemble and (b) how interdependent team interactions of shared mental models, closed-loop communication, and/or mutual trust contribute to the function of and learning within this handbell ensemble. The case was limited to one handbell ensemble known as the Campana Ringers, a group who performed for a community church. Members included their director and 13 ringers, one of whom was myself. In individual and group sessions, I interviewed the ensemble director and all team members. Observational and rehearsal notes were coded and primary themes were presented through the core components and coordinating mechanisms of the Big Five theory of teamwork (Salas et al., 2005). Secondary themes emerged connected to the uniqueness of handbell playing and co-mentoring occurring in the ensemble. In data from my findings, I recognized all elements of the Big Five theory were present in interactions between handbell ensemble members. Implications from this case study are connected to co-mentoring, a type of collaborative learning utilizing reciprocal teaching and learning (Mullen, 2005). Findings from this study may inform music educators in community and school settings who wish to develop or incorporate components of teamwork and co-mentoring practices into their ensembles.

Thesis advisor: Ana M. Martínez Alemán / This qualitative research study examined the design of collaborative learning experiences in an online graduate course in educational leadership. Based on principles of design-based research, this single case study analyzed the design process among the faculty member and learning design team who created the course. Data were also gathered from the first time the course was completed by students. Content analysis was the primary method to analyze data sources that included design documentation, interviews with faculty and the learning design team, images of course modules in the university Learning Management System, transcripts of synchronous learning exchanges among students and the faculty, team-based assignment submissions, and a survey of students. Findings revealed that the design of collaborative learning experiences was dependent on the nature of the learning goals. The instructor oriented students toward the collaborative culture of the online course and employed numerous learning supports and facilitation strategies to aid them. Collaborative learning design was rooted in the learning sciences, social interdependence theory, and the conceptualization of the virtual classroom as a space for play and creativity. Student collaboration involved synthesis of readings, team-based design exercises, and supporting each other in making progress towards program-level goals. Students regularly engaged in metacognitive activity to reflect on their learning individually and as a collective. Students found the learning supports valuable and collaborative learning experiences challenging but affirming of their identities as graduate students. This study contributes to theory about designing and facilitating online collaborative learning in graduate programs and offers design considerations to guide future efforts in learning design. / Thesis (PhD) — Boston College, 2023. / Submitted to: Boston College.

New Product Development is a key strategy for company performance. Competencies involved in those projects are numerous and varied. Companies increasingly involve their suppliers in codevelopment projects to gather the most relevant knowledge, improve product quality and reduce time to market. Different levels of supplier involvement are defined in literature: white, gray and black box according to their responsibilities. This master thesis focuses on  he collaboration between supplier and customer in the case of New Product Development.  eflecting on existing literature, this master thesis first proposes a new taxonomy of boundary spanning, based on four main areas: knowledge transfer, knowledge translation, knowledge transformation and coordination. Secondly, each area is broken down into collaborative activities, which in turn are linked to the proper Information Technologies (IT). Finally, this typology is successfully confronted to two case studies.

As collaborative robotics become more prevalent, it is desirable to improve the inherent robot safety, on a mechanical level, while maintaining good position tracking. One method is to replace the electric motor+gearing currently used with an alternate actuator which introduces less inertia, friction, and stiffness. A promising approach is the use of hybrid pneumatic-electric actuators (HPEAs). A first generation (GEN1), proof-of-concept, HPEA with low payload capacity and poor mechanical reliability was improved upon to produce the next generation of HPEA. The 2nd generation (GEN2) actuator developed in this work was designed to increase payload capacity and improve mechanical reliability while maintaining low inertia, low friction and low stiffness. The torque capacity was improved by 511% while increasing inertia by only 292%. The majority of the system was modeled via relevant physical laws. The solenoid valves’ inverse model was provided by a black box artificial neural network (ANN), and the electric motor’s was empirical. The models were used to develop a position controller with an inner loop pressure controller based upon the ANN. An alternate (non-model-based) pressure controller was also developed to compare to the ANN based controllers. The system could operate as a purely pneumatic actuator, or as a HPEA. Experimentally it was found that the position control based upon the two pressure controllers led to similar performance, but the ANN based were superior more often. The hybrid mode reduced the purely pneumatic mode position error for vertical cycloidal position tracking by approximately 55%. The GEN2 achieved lower position tracking errors as compared to prior works of other HPEAs as well as purely pneumatic actuator control publications. Compared to the GEN1, the GEN2 achieved better position tracking errors in both pneumatic and hybrid operation. The GEN2 will serve as a superior testbed for future HPEA control and collaborative robotics research. / Thesis / Master of Applied Science (MASc) / Robots which work directly with people are becoming increasingly numerous in industry as their costs decrease. As robots and humans work more and more closely there is a desire for the robot to be more inherently safe, by merit of the underlying mechanical design. Previous research resulted in a prototype hybrid pneumatic-electric actuator (HPEA) designed to improve inherent safety by merit of its low inertia, low friction, and low stiffness. This prototype proved successful, but was of low payload capacity and unreliable mechanical design. The goal of the research was to design, build, model, control, and validate a second generation HPEA, with a larger payload capacity and of more reliable mechanical design while maintaining low friction, inertia and stiffness. Furthermore the improved actuator should maintain or improve upon the good position trajectory tracking of the prior actuator. These goals were successfully achieved with the improved prototype developed in this work.

Objectives: We investigated pediatric rare disease researchers’ experiences and perspectives with research collaborations involving industry partners. Methods: This mixed methods study included a cross-sectional survey of academic/hospital-based Canadian pediatric rare disease researchers which informed semi-structured interviews with a subsample of survey participants. We analyzed survey data descriptively and interview data thematically, integrating findings narratively. Results: Of 126 survey respondents, 59 (47%) reported research collaborations with industry; we interviewed 10 of these researchers. Important benefits to collaborations with industry reported by survey participants and interviewees included access to funding and resources, while disadvantages stemmed from perceptions that partners had different motivations. Interviewees provided advice for future researchers including careful selection of an industry partner, relationship building, clear expectations, and utilizing supportive institutional structures. Conclusion: Our findings provide insights into the experiences of pediatric rare disease researchers and offer suggestions on how to conduct successful collaborative research with industry.

While it is commonly understood by occupational therapy practitioners that collaborative goal setting leads to increased goal achievement (Sugavanam, Mead, Bulley, Donaghy, & van Wijck, 2013), the current literature shows that people with post stroke aphasia are not optimally involved in the collaborative goal setting process (Berg, Askim, Balandin, Armstrong, & By Rise, 2017; Berg, By Rise, Balandin, Armstrong, & Askim, 2016; Rohde, Townley-O’Neill, Trendall, Worrall, & Cornwell, 2012). This leads to reduced goal achievement (Sugavanam, Mead, Bulley, Donaghy, & van Wijck, 2013) and ultimately less leisure and social participation (Hilari, 2011; Eriksson, Aasnes, Tistad, Guidetti, & von Koch, 2012; Nätterlund, 2010). ClientCollab is a theory-based and evidence-driven online visual supplement to the Canadian Occupational Performance Measure (COPM), designed to reduce the cognitive and communication burdens of the COPM and assist the practitioner and client with aphasia in the goal setting process. ClientCollab is guided by research on reading and pictorial comprehension of people with aphasia as well as by the Universal Design of Learning (UDL) theory. The online program is available free of charge at www.clientcollab.net and is designed to be used in conjunction with the COPM to assist the occupational therapy practitioner and client in identifying occupational performance issues. The content of the program parallels the section and subsection breakdown of the COPM and is designed for use during step one of the COPM to assist in the identification of occupational performance issues. The objective of the program is to increase communication between client and practitioner during the goal setting process as well as to increase the number of goals developed with client input. ClientCollab is meant to act as a visual supplement to the goal setting section of the COPM, however it is not meant or able to fully replace the COPM, and must be used in conjunction with the paper or online version of the COPM. In conclusion, ClientCollab aims to decrease the cognitive and communication barriers limiting people with aphasia from completing the COPM in hopes of facilitating increased collaborative goal setting and ultimately increased goal achievement in this population.

The overarching purposes of this research were to (a) explore an under-acknowledged and under-emphasized aspect of the sport-related concussion experience: psychosocial factors of the injury experience and (b) identify possible intervention opportunities to support the associated psychological and social needs. A collaborative inquiry (Bray et al., 2000) was employed to generate data on the psychosocial experience of concussions in elite sport and to co-develop support strategies from a sport psychology lens. This qualitative research project involved three phases during which psychological and social needs, as well as psychosocial factors that facilitated and/or hindered the concussion recovery process, were discussed through two lenses. The first lens was an experiential one, whereby elite athletes who became concussed as a result of their sport engagement shared their experiences (Phase A). The second lens was that of professional expertise, whereby mental performance consultants who work in elite sport and deliver psychosocial support to concussed elite athletes shared their perspectives and clients’ experiences (Phase B). Following the sharing of these perspectives, a community of practice (Wenger et al., 2002) of mental performance consultants was formed to collaboratively discuss how mental performance consultants might be able to support the aforementioned psychological and social needs, and ultimately, concussion recovery (Phase C). Phase A. Ten elite athletes (as defined by Swann et al., 2015) participated in semi-structured focus groups (Smith & Sparkes, 2016). Athletes discussed their experiences of injury, challenges, facilitators and barriers to recovery, support mechanisms, support that was lacking but desired, and what they would do to help someone else with a concussion. The transcripts from these focus groups (n = 5, M = 58.1 min, Range: 46-88 min), follow-up questions, and informal conversations were analyzed using thematic narrative analysis (Smith, 2016), contributing to an understanding of the athletes’ lived experiences. Phase B. Nine mental performance consultants from the Canadian Sport Psychology Association and/or Association for Applied Sport Psychology who were working in high-performance sport participated in three focus groups (M = 79 min, Range = 66-98 min). Mental performance consultants were asked about their time in the field and other aspects of their consulting experience (e.g., sports, integrated within teams or not), the types of interventions they have done with concussed athletes, their perceptions of psychosocial support during the phases of concussion management, and challenges to effective service delivery. Verbatim transcripts of these focus groups were sent to the consultants and member reflections were requested (Smith & McGannon, 2018). The generated data were thematically analyzed using a six-phase cyclical and iterative approach (Braun et al., 2016). Phase C. Eight mental performance consultants from various sport contexts formed a community of practice (Wenger et al., 2002; E. Wenger-Trayner & Wenger-Trayner, 2021). The group met over a period of four months (n = 8 meetings, M = 80 min, Range = 60-90 min). These meetings were intended to address the identified interests of the members of the community regarding support for concussed elite athletes. Concussion symptomatology, management efforts, and research were discussed; and professional scope of practice and intervention opportunities were explored through best practice discussions, client case studies, and engagements with two external experts. Mental performance consultants completed individual reflections (i.e., weekly reflective questions, value creation stories, personal value narratives; Wenger et al., 2011; E. Wenger-Trayner & Wenger-Trayner, 2015) resulting in 34 single-spaced pages of generated data, which were analyzed using the Value Creation Framework (E. Wenger-Trayner & Wenger-Trayner, 2015; 2021). The results of this multi-phase collaborative inquiry are presented in four articles. The first article offers a multi-systems perspective (Bronfenbrenner, 1977; 1979; 1992) on athletes’ concussion experiences by exploring two collaboratively created narratives (Wertz, 2011; Willis, 2019) from the engagements with athletes in Phase A. Five themes (i.e., athletic identity, (dis)trust in relationships, concussion protocols, sport culture, and timing related to major events and recovery) are discussed. The second article combines the perspectives of athletes from Phase A and mental performance consultants in Phase B to identify psychological and social needs across the concussion recovery process. Four psychological needs (i.e., acceptance, normality, confidence, self-efficacy) and two social needs (i.e., trust in relationships, social support) were identified by both populations. The third article was collaboratively written to practically present how and where mental performance consultants can support concussed athletes across the phases of the injury based on the discussions in Phase C. Scope of practice, collaboration opportunities, and intervention strategies are discussed across four phases of injury (i.e., pre-injury, injury onset, rehabilitation, return to sport). The fourth article reflects the mental performance consultants’ participatory experiences in Phase C by exploring the value of the community of practice as a professional development and knowledge translation tool. Positive value was experienced across all eight cycles of the Value Creation Framework. Through the general discussion and practical implications sections of this dissertation, these results are situated within the landscapes of concussion research and practice to highlight opportunities for transforming concussion protocols and broadening the overall lens through which the concussion experience can be examined.

The purpose of this study was to measure the impact of caregiver-student collaborative learning classes on an urban community. The study examined whether the self-efficacy of the caregivers increased with helping their children with school work due to the caregiver-student classes. The study also examined whether providing access to a resource not normally provided within this particular community led to increased self-efficacy within caregivers. The research questions that guided the study were as follows: How do collaborative caregiver-student classes that focus on collaborative strategies impact the self-efficacy of the caregivers in helping their children with school work? How does increasing access to educational services impact the self-efficacy of the caregivers who participate in collaborative caregiver-student classes? The researcher collected data through classroom observations, reflections from participants, and an initial focus group and closing individual interview. Classes were taught by a co-teacher selected by the researcher with the input of the principal. Four total sessions were held, three of which included the teaching of collaborative learning strategies, and the last of which was an individual interview. Overall, data indicated increased self-efficacy within caregivers. The caregiver roles within the neighborhood proved not to always be between an adult and child, but rather cousins and siblings who may have been close in age. Families within the neighborhood exchanged care in different ways according to their culture, work demands, and family dynamic. This program led to strengthened relationships between home and school, as well as enhanced self-efficacy and stronger relationships between caregivers and students.

With the rapid development of the Internet, increasingly universities and colleges transfer some of their teaching assignments online. Online learning plays an important role in assisting or sometimes substituting for the traditional face-toace learning. An online message board is one of several online communication tools which are used to assist online learning. We have conducted a study on the role of the online message board in teaching one of these courses, an introductory course in calculus-based physics. The study analyzed students? use of the message board and investigated whether use is correlated with performance in the class. Results suggest that students have benefited from using the online message board. Both homework related message board activities and non-learning message boardn activities were found to be correlated significantly to the grades the students earned in the course.
