Optimizing the SICStus Prolog virtual machine instruction set

The Swedish Institute of Computer Science (SICS) is the vendor of SICStus Prolog. To decrease execution time and reduce space requirements, variants of SICStus Prolog's virtual instruction set were investigated. Semi-automatic ways of finding candidate sets of instructions to combine or specialize were developed and used. Several virtual machines were implemented and the relationship between improvements by combinations and by specializations were investigated. The benefits of specializations and combinations of instructions to the performance of the emulator is on the average of the order of 10%. The code size reduction is 15%

Older Adults Experiences of Reflective STRENGTH-Giving Dialogues: An Interview Study

Background: A major health problem that frequently accompanies old age is long-term pain, but pain must be acknowledged by older adults and health care providers. Interventions are needed to alleviate pain and suffering while holistically providing health care that promotes wellbeing. The intervention project, Reflective STRENGTHGiving Dialogues© (STRENGTH) was implemented to increase health and wellbeing among community dwelling older adults living with long-term musculoskeletal pain at home. Aim: The aim of this study was to describe the older adults\u27 experiences of the intervention Reflective STRENGTH-Giving Dialogue. Method: A life world hermeneutic approach was used in collection and analysis of data. Twenty community dwelling older adults participated were interviewed in their homes after the intervention. Findings: The findings consisted of five themes and showed that the older adults experienced the Reflective STRENGTH-Giving Dialogues as a continuous and trusting relationship that alleviates the pain and breaks the loneliness. They expressed it as a new way to talk about life with pain. The dialogues supported reflection and memory and resulted in a transition in orientation in life. Conclusion: The Reflective STRENGTH-Giving Dialogues helped the older adults to increase their intellectual, emotional, and physical engagement in daily living. The dialogues facilitated a transition in orientation from past to present, to the future, and from obstacles to opportunities. The dialogues were oriented towards enjoyments, meaning, courage and strength in life as a whole which promoted the older adults’ sense of well-being and vitality. The dialogues also facilitated carrying out small and large life projects. The Reflective STRENGTH-Giving Dialogues created a deepened caring relationship that contributed to an increased sense of security, strength and courage, all of which enhanced the potential for better health and wellbeing

From ethical approval to an ethics of care: Considerations for the inclusion of older adults in ethnographic research from the perspective of a ‘humanisation of care framework’

A deeper understanding of care demands the methodological finesse of qualitative research: we must observe, listen, and witness to expose what matters to care recipients. In this paper, we – a team of three: one early-career researcher and two supervisors – reflect on our experiences of designing and then seeking ethics approval for ethnographic research on care for older adults, many of whom demonstrate a lack of capacity to consent to research. Viewing experiences of well-being and dignity as embedded within interpersonal negotiations, this study privileges care home residents' daily life, looking to stories and observations of daily life to reveal the complexities of well-being in the care home setting. This paper emphasizes the importance of using qualitative research methods to gain a deeper understanding of care practices, particularly in the context of care for older adults with varying cognitive capacities. By privileging the daily life experiences of care home residents and employing the logic of process consent, we aim to include the voices of all participants, not just those who can provide written informed consent. However, obtaining ethics approval for this type of research presents several challenges, requiring careful negotiation and the inclusion of consultee advice. This paper highlights the tensions between procedural ethics and the need for better inclusion of vulnerable populations in ethnographic research on care. By addressing these challenges, we can move towards a more context-sensitive and humanised approach to research ethics that values the lived experiences of care recipients

Cell Migration in the Immune System: the Evolving Inter-Related Roles of Adhesion Molecules and Proteinases

Leukocyte extravasation into perivascular tissue during inflammation and lymphocyte homing to lymphoid organs involve transient adhesion to the vessel endothelium, followed by transmigration through the endothelial cell (EC) layer and establishment of residency at the tissue site for a period of time. In these processes, leukocytes undergo multiple attachments to, and detachments from, the vessel-lining endothelial cells, prior to transendothelial cell migration. Transmigrating leukocytes must traverse a subendothelial basement membrane en route to perivascular tissues and utilize enzymes known as matrix metalloproteinases to make selective clips in the extracellular matrix components of the basement membrane. This review will focus on the evidence for a link between adhesion of leukocytes to endothelial cells, the induction of matrix metalloproteinases mediated by engagement of adhesion receptors on leukocytes, and the ability to utilize these matrix metalloproteinases to facilitate leukocyte invasion of tissues. Leukocytes with invasive phenotypes express high levels of MMPs, and expression of MMPs enhances the migratory and invasive properties of these cells. Furthermore, MMPs may be used by lymphocytes to proteolytically cleave molecules such as adhesion receptors and membrane bound cytokines, increasing their efficiency in the immune response. Engagement of leukocyte adhesion receptors may modulate adhesive (modulation of integrin affinities and expression), synthetic (proteinase induction and activation), and surface organization (clustering of proteolyric complexes) behaviors of invasive leukocytes. Elucidation of these pathways will lead to better understanding of controlling mechanisms in order to develop rational therapeutic approaches in the areas of inflammation and autoimmunity

Low-Carbon Sustainable Precincts: An Australian Perspective

Australia’s urban built environment contributes significantly to the nation’s greenhouse gas emissions; therefore, encouraging urban development to pursue low-carbon outcomes will aid in reducing carbon in the overall economy. Cities and urban areas are configured in precincts, which have been identified as an ideal scale for low-carbon technologies that address energy, water and waste. Even though new governance models and systems are being created to enable low-carbon precincts to operate with a degree of independence within a broader centralised utility structure, greater effort is required to refocus governance on this smaller scale of delivery. Furthermore, at this time, no consistent carbon accounting framework is in place to measure emissions or emission reductions at this scale, thereby limiting the ability to acknowledge or reward progressive, sustainable low-carbon developments. To respond to this situation, a framework is proposed that could form both the basis of a carbon certification scheme for the built environment and provide a platform for generating carbon credits from urban development

Metrics for optimising the multi-dimensional value of resources recovered from waste in a circular economy: A critical review

© 2017 The Authors - Established assessment methods focusing on resource recovery from waste within a circular economy context consider few or even a single domain/s of value, i.e. environmental, economic, social and technical domains. This partial approach often delivers misleading messages for policy- and decision-makers. It fails to accurately represent systems complexity, and obscures impacts, trade-offs and problem shifting that resource recovery processes or systems intended to promote circular economy may cause. Here, we challenge such partial approaches by critically reviewing the existing suite of environmental, economic, social and technical metrics that have been regularly observed and used in waste management and resource recovery systems' assessment studies, upstream and downstream of the point where waste is generated. We assess the potential of those metrics to evaluate ‘complex value’ of materials, components and products, i.e., the holistic sum of their environmental, economic, social and technical benefits and impacts across the system. Findings suggest that the way resource recovery systems are assessed and evaluated require simplicity, yet must retain a suitable minimum level of detail across all domains of value, which is pivotal for enabling sound decision-making processes. Criteria for defining a suitable set of metrics for assessing resource recovery from waste require them to be simple, transparent and easy to measure, and be both system- and stakeholder-specific. Future developments must focus on providing a framework for the selection of metrics that accurately describe (or at least reliably proxy for) benefits and impacts across all domains of value, enabling effective and transparent analysis of resource recovery form waste in circular economy systems.We gratefully acknowledge support of the UK Natural Environ-ment Research Council (NERC) and the UK Economic and SocialResearch Council (ESRC) who funded this work in the context of‘Complex Value Optimisation for Resource Recovery’(CVORR)project (Grant No. NE/L014149/1)
