Steel to Concrete Connections

This project consists of the design, installation, and implications of steel beam to concrete wall connections. A new, modern single family home in Beverly Hills was the site of the connections. Calculations and details of gravity and drag beams were carried out, communication with the steel fabricator shop and the architect were performed, and a subsequent site visit to view construction methods was completed. Takeaways from the project were the economics of the connections designed, communication within separate disciplines on the site, and visualization of designed elements in the real-world

Towards Integrated Physical Activity Profiling

Recently, there has been some discussion of whether it is possible to score highly in one dimension of physical activity behaviour (e.g., moderate intensity exercise) whilst also scoring poorly in another (e.g., sedentary time). Interestingly, direct empirical observations to support these proposals are lacking. New technologies now enable the capture of physical activity thermogenesis on a minute-by-minute basis and over a sustained period. We used one of the best available technologies to explore whether individuals can score differently in various physiologically-important physical activity dimensions. We determined minute-by-minute physical activity energy expenditure over 7 days in 100 men aged 28 ± 9 years. We used combined accelerometry and heart rate with branched equation modelling to estimate energy expenditure and extracted data for key physical activity outcomes and descriptors. Although some physical activity outcomes were tightly correlated, the attainment of one threshold for a given physical activity dimension did not automatically predict how well an individual scored in another dimension (with bivariate correlations ranging from 0.05 to 0.96). In one illustrative example of this heterogeneity, although 41 men showed a relatively low Physical Activity Level (total energy expenditure/resting energy expenditure ≤ 1.75), only 17% (n=7) of these men showed consistently low physical activity across other dimensions (moderate intensity activity, vigorous intensity activity, and sedentary time). Thus, physical activity is highly heterogeneous and there is no single outcome measure that captures all the relevant information about a given individual. We propose that future studies need to capture (rather than ignore) the different physiologically-important dimensions of physical activity via generation of integrated, multidimensional physical activity 'profiles'

The understanding, acceptability, and relevance of personalised multidimensional physical activity feedback among urban adults: evidence from a qualitative feasibility study in Sri Lanka

BackgroundWearable technologies are being used to provide personalised feedback across multiple physical activity dimensions in countries such as the UK, but their feasibility has not been tested in South Asia, where physical inactivity is increasing. This study assessed the understanding, acceptability, and relevance of personalised multidimensional physical activity feedback in urban dwellers in Colombo, Sri Lanka.MethodsA qualitative feasibility study was conducted among 35 adults to assess a community-based approach to provide multidimensional physical activity feedback. Healthy adults, adults at risk of non-communicable diseases and community-based primary healthcare professionals wore a physical activity monitor for 7 days and were then guided through their personalised multidimensional physical activity feedback. One-to-one interviews were conducted, transcribed verbatim and analysed using framework analysis.ResultsFour themes were generated: understanding of personalised physical activity feedback, perceived novelty of the feedback, motivation, and consideration of the multidimensional nature of physical activity. A majority of participants required guidance initially to understand the feedback, following which most were quickly able to interpret the data shown, and were willing to use the feedback as a basis for identifying goals to improve physical activity. Participants perceived the feedback and its delivery as novel because it provided new knowledge about physical activity guidelines and awareness on their own behaviour through graphics. Comparisons of personal performance against recommended physical activity levels and information on sedentary time were the most commonly motivating aspects of the feedback, prompting talk about behaviour change. All three groups showed poor planning on goal achievement, with some noticeable differences between those with and without health risk of non-communicable diseases. Following the feedback, most participants understood that physical activity is composed of several dimensions, while around half could recognise more suitable options to change behaviour. Of the physical activity dimensions, calorie burn received more attention than others.ConclusionsMultidimensional physical activity feedback was considered understandable and acceptable and has the potential to support behaviour change among urban Sri Lankans with or without identified health risk. These findings highlight the feasibility of this technology-enabled approach as a personalised intervention to improve knowledge and motivation for physical activity behaviour

Carbohydrate availability as a regulator of energy balance with exercise:Carbohydrates and energy balance

We explore the novel hypothesis that carbohydrate availability is involved in the regulation of energy balance with exercise, via hormonal and neural signals. We propose that carbohydrate availability could play a direct mechanistic role and partially explain previously documented relations between a more active lifestyle and tighter control of energy balance.</p

Can evolutionary mismatch help generate interest in health promotion messages?

Background: Generating interest in health interventions is an important first step towards engagement with health promotion and effecting behaviour change. This study explored whether framing health information about physical activity and diet from an evolutionary mismatch perspective could help to generate interest in health promotion among overweight and inactive adults. Evolutionary mismatch theory proposes that human cultural evolution has occurred too rapidly for biological evolution to keep up, creating a mismatch between genes and lifestyles that gives rise to chronic diseases such as type 2 diabetes. Method: A total of 18 adults completed interviews in which they viewed and discussed a variety of mismatch-framed health information resources. Follow-up questions assessed if and what participants had thought about the information in the week after the interview. Transcripts were thematically analysed. Results: Participants found the evolutionary perspective to be novel and interesting. It also provided a meaningful rationale for behaviour change. However, there was some evidence of negative elaboration, which would need to be managed if implementing this approach. Conclusion: Adopting a mismatch perspective can help to engage audiences with important health information.</p

Shifting the EU Taxonomy from Theory to Practice: A Review of the Literature highlighting Potential Academic Contributions to its Adoption, Implementation, and Impact

The EU Taxonomy seeks to identify those sustainable economic activities, thereby supporting climate change mitigation and adaptation. Recent legislation underpinning the EU Taxonomy, such as the Non-Financial Reporting Directive (NFRD) and the Sustainable Finance Disclosure Regulation (SFDR), highlight the urgency for academic contributions that might shed light on its operationalisation. At this embryonic stage in the Taxonomy’s lifecycle, there is potential for the academic community to contribute to understanding its implications. Hence, we undertake a thematic analysis of predominantly, but not exclusively, professional literature to prioritise potential empirical research or conceptualisations that might offer insights for finance and accounting professionals, regulators, policymakers, investors and businesses. Our literature search is limited to literature that makes explicit reference to the Taxonomy between 2018 and 2021. We find that little is understood on how investors or businesses intend to disclose against the taxonomy or on the challenges associated with disclosure. With sustainable finance emerging in Ireland, we propose an exploratory study of this sector’s readiness to operationalise the taxonomy and offer a conceptual framework based on co-evolution theory (Foxon, 2011) bounded by three initial conditions: [1] skills and capability and [2] access to ESG data and [3] regulatory alignment

A review of instrumental variable estimators for Mendelian randomization.

Instrumental variable analysis is an approach for obtaining causal inferences on the effect of an exposure (risk factor) on an outcome from observational data. It has gained in popularity over the past decade with the use of genetic variants as instrumental variables, known as Mendelian randomization. An instrumental variable is associated with the exposure, but not associated with any confounder of the exposure-outcome association, nor is there any causal pathway from the instrumental variable to the outcome other than via the exposure. Under the assumption that a single instrumental variable or a set of instrumental variables for the exposure is available, the causal effect of the exposure on the outcome can be estimated. There are several methods available for instrumental variable estimation; we consider the ratio method, two-stage methods, likelihood-based methods, and semi-parametric methods. Techniques for obtaining statistical inferences and confidence intervals are presented. The statistical properties of estimates from these methods are compared, and practical advice is given about choosing a suitable analysis method. In particular, bias and coverage properties of estimators are considered, especially with weak instruments. Settings particularly relevant to Mendelian randomization are prioritized in the paper, notably the scenario of a continuous exposure and a continuous or binary outcome.Stephen Burgess is supported by the Wellcome Trust (grant number 100114).
