Music technologies: ppportunities for social connection

Strategies to support psychosocial well-being in older adults are desperately needed. A developing body of research points to the relationship between continued engagement with the arts and maintaining mental health and quality of life (Wang, et al., 2020). Music is an effective, non-pharmacological tool with many social and emotional benefits particularly for older adults (Creech, et al., 2014),and technology is posited to play a role in making music interventions more accessible and cost-effective (Garrido, et al., 2018). In addition to a brief overview of how musical engagement can support older Australians' psychosocial well-being, this presentation will discuss technologies for both consuming and making music. This will focus on recent empirical research findings comparing the impact and benefit of technology-driven music opportunities designed to promote social connection. Because technologies continue to develop, it is important to consider the underpinning principles corresponding to use and engagement. These principles can guide the purchase and implementation of these technologies in aged care. We will focus on fostering musical engagement through technologies for social connection and well-being. Through this lens, we will explore: 1. Technology Types – what equipment is needed, considering price, availability, and levels of user interaction? 2. Skills & Education – how to make use of existing staff and resident knowledge, and sourcing relevant education & training. 3. Flexibility & Accessibility – how easy is it to mould or modify music technology activities to residents’ personal choices as well as their physical/ cognitive abilities? 4. Sustainability – what is reproducible and sustainable in the face of staff/resident changes? I.e. how to make sure the newly purchased technology doesn’t end up in the cupboard?! Addressing aspects of implementation relevant to practitioners creates the link between increasing awareness of the benefits of music consumption and creation and being able to translate these empirical research findings into everyday use

Assessing Student Learning Outcomes in Physical Education K-12 Teaching: A Whole-Program Revision to Meet New Standards and Institutional Learning Outcomes

The purpose of this project was to evaluate, revise, and align program-level assessments for the Physical Education K-12 Teaching program. Major goals for the project included (a) construction of a program-wide course matrix with SLOs, state and national educator standards, UNC Institutional Learning Outcomes, and course assessments; (b) construction/revision of assessment methods and criteria; and (c) integration of a tagging system within Canvas/LiveText to monitor outcome achievements. This presentation will describe an overview of the process, major updates and changes to the program, and future steps for implementation

Examining the Impact of Mental Health Education on Bias and Stigma in CIT Trained Officers

The purpose of this quantitative, correlational nonexperimental research was to examine the relationship between the mental health education received through Crisis Intervention Team (CIT) training and the perceptions of public mental health stigma, self-stigma, and attitudes toward seeking mental health services among law enforcement officers. The study’s theoretical framework integrated gender-role conflict theory and Goffman’s stigma theory in explaining the influence of the police culture on officers’ adoption of more traditional masculine roles. This research used three instruments: the Attitudes to Mental Illness questionnaire to measure perceptions of public stigma, the Self-Stigma of Seeking Help Scale to measure self-stigma, and the Inventory of Attitudes Toward Seeking Mental Health Services to measure attitudes toward seeking mental health services. The sample consisted of 48 law enforcement officers from across the United States who completed an online 60-question survey. A multivariate analysis of variance revealed no mean differences in perceptions of public stigma, self-stigma, and attitudes toward seeking mental health between CIT-trained and non-CIT-trained officers. This finding indicated that mental health education received through CIT training did not predict perceptions of stigma or attitudes toward seeking mental health services. Future research could compare law enforcement departments and employ longitudinal designs. Research findings have the potential to effect positive social change by bringing awareness of the need for improving mental health training for law enforcement. Such efforts are likely to enrich the mental health quality of officers and the communities they serve

Technology in University Physical Activity Courses: A Mini-Ethnographic Case Study

As younger generations become increasingly reliant on technology, higher educational institutions must continually attempt to stay with or ahead of the curve to foster 21st century teaching and learning. College and university physical activity courses (PACs) are encouraged to incorporate technology for effective pedagogical practices. No qualitative research has specifically examined the culture of PACs instructors’ attitudes and experiences with technology as a pedagogical tool. A mini-ethnographic case study explored the use of technology among seven graduate teaching assistants who shared their pedagogical experiences, teaching practices, and perceptions of technology within PACs. Using an interpretive phenomenological analysis, composite narrative accounts were presented to highlight unique characteristics of PAC instructors and develop meaning from their lived experiences. The findings revealed that PAC instructors use varying forms of technology, but all instructors rely on learning management systems as a pedagogical tool, which can be influenced by campus environment, pedagogical experiences, and social support. This pilot study contributes to the current gap in research related to technology in PACs and addresses the need to properly prepare instructors to teach in the digital age

Association patterns and foraging behaviour in natural and artificial guppy shoals

Animal groups are often nonrandom assemblages of individuals that tend to be assorted by factors such as sex, body size, relatedness and familiarity. Laboratory studies using fish have shown that familiarity among shoal members confers a number of benefits to individuals, such as increased foraging success. However, it is unclear whether fish in natural shoals obtain these benefits through association with familiars. We investigated whether naturally occurring shoals of guppies, Poecilia reticulata, are more adept at learning a novel foraging task than artificial (in which we selected shoal members randomly) shoals. We used social network analysis to compare the structures of natural and artificial shoals and examined whether shoal organization predicts patterns of foraging behaviour. Fish in natural shoals benefited from increased success in the novel foraging task compared with fish in artificial shoals. Individuals in natural shoals showed a reduced latency to approach the novel feeder, followed more and formed smaller subgroups compared to artificial shoals. Our findings show that fish in natural shoals do gain foraging benefits and that this may be facilitated by a reduced perception of risk among familiarized individuals and/or enhanced social learning mediated by following other individuals and small group sizes. Although the structure of shoals was stable over time, we found no direct relationship between shoal social structure and patterns of foraging behaviour

MAPping the Chiral Inversion and Structural Transformation of a Metal-Tripeptide Complex having Ni-SOD Activity

To access the final edited and published work see http://doi.org/10.1021/ic102295s.The metal abstraction peptide (MAP) tag is a tripeptide sequence capable of abstracting a metal ion from a chelator and binding it with extremely high affinity at neutral pH. Initial studies on the nickel-bound form of the complex demonstrate that the tripeptide asparagine-cysteine-cysteine (NCC) binds metal with 2N:2S, square planar geometry and behaves as both a structural and functional mimic of Ni superoxide dismutase (Ni-SOD). Electronic absorption, circular dichroism (CD), and magnetic CD (MCD) data collected for Ni-NCC are consistent with a diamagnetic NiII center. It is apparent from the CD signal of Ni-NCC that the optical activity of the complex changes over time. Mass spectrometry data show that the mass of the complex is unchanged. Combined with the CD data, this suggests that chiral rearrangement of the complex occurs. Following incubation of the nickel-containing peptide in D2O and back-exchange into H2O, incorporation of deuterium into non-exchangeable positions is observed, indicating chiral inversion occurs at two of the alpha carbon atoms in the peptide. Control peptides were used to further characterize the chirality of the final nickel-peptide complex, and DFT calculations were performed to validate the hypothesized position of the chiral inversions. In total, these data indicate Ni-SOD activity is increased proportionally to the degree of structural change in the complex over time, as cross-correlation between the change in CD signal and change in SOD activity reveals a linear relationship

Controlling the Chiral Inversion Reaction of the Metallopeptide Ni-Asparagine-Cysteine-Cysteine with Dioxygen

This document is the Accepted Manuscript version of a Published Work that appeared in final form in the Inorganic Chemistry, copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see http://doi.org/10.1021/ic301717q.Synthetically generated metallopeptides have the potential to serve a variety of roles in biotechnology applications, but the use of such systems is often hampered by the inability to control secondary reactions. We have previously reported that the NiII complex of the tripeptide LLL-asparagine-cysteine-cysteine, LLL-NiII-NCC, undergoes metal-facilitated chiral inversion to DLD-NiII-NCC, which increases the observed superoxide scavenging activity. However, the mechanism for this process remained unexplored. Electronic absorption and circular dichroism studies of the chiral inversion reaction of NiII-NCC reveal a unique dependence on dioxygen. Specifically, in the absence of dioxygen, the chiral inversion is not observed, even at elevated pH, whereas the addition of O2 initiates this reactivity and concomitantly generates superoxide. Scavenging experiments using acetaldehyde are indicative of the formation of carbanion intermediates, demonstrating that inversion takes place by deprotonation of the alpha carbons of Asn1 and Cys3. Together, these data are consistent with the chiral inversion being dependent on the formation of a NiIII-NCC intermediate from NiII-NCC and O2. The data further suggest that the anionic thiolate and amide ligands in NiII-NCC inhibit Cα–H deprotonation for the NiII oxidation state, leading to a stable complex in the absence of O2. Together, these results offer insights into the factors controlling reactivity in synthetic metallopeptides

A novel tripeptide model of nickel superoxide dismutase

This document is the Accepted Manuscript version of a Published Work that appeared in final form in the Inorganic Chemistry, copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see http://doi.org/10.1021/ic901828m.Nickel superoxide dismutase (Ni-SOD) catalyzes the disproportionation of superoxide to molecular oxygen and hydrogen peroxide, but the overall reaction mechanism has yet to be determined. Peptide-based models of the 2N:2S nickel coordination sphere of Ni-SOD have provided some insight into the mechanism of this enzyme. Here we show that the coordination sphere of Ni-SOD can be mimicked using the tripeptide asparagine-cysteine-cysteine (NCC). NCC binds nickel with extremely high affinity at physiological pH with 2N:2S geometry, as demonstrated by electronic absorption and circular dichroism (CD) data. Like Ni-SOD, Ni-NCC has mixed amine/amide ligation that favors metal-based oxidation over ligand-based oxidation. Electronic absorption, CD, and magnetic CD data (MCD) collected for Ni-NCC are consistent with a diamagnetic Ni(II) center bound in square planar geometry. Ni-NCC is quasi-reversibly oxidized with a midpoint potential of 0.72(2) V (versus Ag/AgCl) and breaks down superoxide in an enzyme-based assay, supporting its potential use as a model for Ni-SOD chemistry
