The emergent roles of a designer in the development of an e learning service

This paper presents reflections from a service design case study and uses it to investigate the emerging roles of a designer. Skills, methodologies and values are drawn through the case study and used to communicate how this contributes to the continuing expansion of the profession today. Seven roles are discussed in this paper: designer as a facilitator, communicator, capability builder, strategist, researcher, entrepreneur and co-creator. The analysis of the activities of the designer in this particular case study has indicated a presence of all of these roles in various degrees. This brings up three key questions for discussion: 1. How can the design profession communicate the value of this role shift to external audiences? 2. How will design education address the requirements of these emerging roles? and more relevant to this workshop, 3. How will businesses utilise these additional skills of a designer

The Effect of Intrafamilial Racism on Biracial Identity Conflict

This study aimed to describe the relation between experiences of intrafamilial racism (i.e., racism perpetrated by family members against other family members), caregiver support, and identity conflict in biracial individuals. Identity conflict is defined as perceived incompatibility with two or more aspects of one’s identity (Sarno et. al., 2015) and is an experience likely to be common among biracial individuals. Regression analyses were conducted to determine the relation between intrafamilial racism, caregiver support, and identity conflict. Moderation analyses were performed to determine the impact of intrafamilial racism on identity conflict at different levels of caregiver support. We hypothesized that intrafamilial racism will have a main effect on identity conflict, such that higher levels of intrafamilial racism will lead to higher levels of identity conflict – this hypothesis was supported by the data. Furthermore, we posited that caregiver support would moderate the relation between intrafamilial racism and identity conflict such that caregiver support would buffer effects of intrafamilial racism on identity conflict. This hypothesis was also supported, suggesting that caregiver support does indeed provide a buffer against identity conflict at low levels of intrafamilial racism, especially for participants with more support from their caregivers. Future studies should include qualitative instruments to deepen understanding of the findings detected here

The Double Duty of the Sakha "Passive"

This paper argues that the Sakha passive morpheme -IlIn- is the fossilised outcome of a bimorphemic 'passive of passive' construction still found in Modern Turkish. While this reanalyzed form is surface homophonous between passive and impersonal functions, we show that the two uses can be differentiated via several syntactic diagnostics and that the Sakha impersonal construction supports the existence of a syntactically-projected impersonal prounoun that may serve as Case Competitor and control/be controlled PRO. At the same time, the diachronic account presented in this paper has important implications for the reconstruction of the Common Turkic voice system and the status of ImpersP and VoiceP as distinct functional projections, instead suggesting that impersonal passive constructions involve iteration of VoiceP

Co-Designing for Dementia

This paper will profile the Alzheimer 100 project and illustrate design practice utilised in a health context. More specifically the paper will discuss: ·         Co-design: The approach used by design consultancy thinkpublic to involve a dementia community throughout the project;·         Key design-led methods used: Including the establishment of a dedicated project website, film-making and a Co-design Day;·         The project’s results: Including a film, signposting service concept and range of product and service prototypes;·         The project’s legacy: Spanning multiple levels including a legacy at a policy level; and ·         The project’s key learnings: Which provide important insights into how design can work effectively in a health context.  Designers and design-led methods can bring innovative solutions to healthcare, but just as importantly, its approach places key healthcare stakeholders at the heart of developing these solutions. Projects such as Alzheimer 100 provide us with practical case studies to deepen our understanding of how designers, design-led methods and approaches can be applied to meet challenges facing healthcare today.

Nitrogen uptake strategies of edaphically specialized Bornean tree species

The association of tree species with particular soil types contributes to high b diversity in forests, but the mechanisms producing such distributions are still debated. Soil nitrogen (N) often limits growth and occurs in differentially available chemical forms. In a Bornean forest where tree species composition changes dramatically along a soil gradient varying in supplies of different N-forms, we investigated whether tree species’ N-uptake and soil specialization strategies covaried. We analyzed foliar 15N natural abundance for a total of 216 tree species on clay or sandy loam (the soils at the gradient’s extremes) and conducted a 15N-tracer experiment with nine specialist and generalist species to test whether species displayed flexible or differential uptake of ammonium and nitrate. Despite variation in ammonium and nitrate supplies and nearly 4 % difference in foliar δ15N between most soil specialists and populations of generalists on these soils, our 15N tracer experiment showed little support for the hypothesis that soil specialists vary in N-form use or the ratios in which they use these forms. Instead, our results indicate that these species possess flexible capacities to take up different inorganic N forms. Variation between soil specialists in uptake of different N forms is thus unlikely to cause the soil associations of tree species and high b diversity characteristic of this Bornean rain forest. Flexible uptake strategies would facilitate N-acquisition when supply rates of N-forms exhibit spatiotemporal variation and suggest that these species may be functionally redundant in their responses to N gradients and influences on ecosystem N-cycles

Security Verification of Low-Trust Architectures

Low-trust architectures work on, from the viewpoint of software, always-encrypted data, and significantly reduce the amount of hardware trust to a small software-free enclave component. In this paper, we perform a complete formal verification of a specific low-trust architecture, the Sequestered Encryption (SE) architecture, to show that the design is secure against direct data disclosures and digital side channels for all possible programs. We first define the security requirements of the ISA of SE low-trust architecture. Looking upwards, this ISA serves as an abstraction of the hardware for the software, and is used to show how any program comprising these instructions cannot leak information, including through digital side channels. Looking downwards this ISA is a specification for the hardware, and is used to define the proof obligations for any RTL implementation arising from the ISA-level security requirements. These cover both functional and digital side-channel leakage. Next, we show how these proof obligations can be successfully discharged using commercial formal verification tools. We demonstrate the efficacy of our RTL security verification technique for seven different correct and buggy implementations of the SE architecture.Comment: 19 pages with appendi

The Public\u27s Perception of an Earthquake Early Warning System: A Study on Factors Influencing Continuance Intention

This paper investigates the perceptions of the New Zealand public towards the Android Earthquake Alert (AEA) system, a public-facing earthquake early warning system. Specifically, it examines the public’s continuance intention towards the AEA system and the influencing factors of satisfaction, confirmation, perceived usefulness, and perceived trust. To gather insights into the public’s perceptions regarding the AEA system, this study distributed online surveys following two separate earthquake alert events on 12 October and 22 October 2021. A total of 524 and 671 participants responded to the two events’ surveys, providing valuable data for analysis and exploration. Structural Equation Modelling of the two datasets revealed that the continuance model fit the data to some extent, especially on the significance of perceived usefulness and perceived trust to continuance intention. However, the results also showed varying results for satisfaction’s relationship with perceived trust and continuance intention. These findings underscore the need for further investigation into the role of satisfaction and perceived trust, considering the evolving nature of EEW technologies and users’ familiarity over time. The descriptive and inferential analysis results raised concerns about potential confusion around the alerts’ source and highlighted the question of responsibility and liability for EEW. Overall, this study contributes to understanding continuance intention in the EEW context and provides insights into the public’s perception of the AEA system in New Zealand. The findings have implications more broadly for EEW systems’ design, implementation, and communication strategies
