Beyond Labor Rights: Which Core Human Rights Must Regional Trade Agreements Protect?
As World Trade Organization (āWTOā) Members relentlessly pursue new regional trade agreements to achieve even faster economic growth than the extraordinary numbers posted by global trade rules, the smaller number of parties and their greater cultural affinity have led negotiators to address the intersection of trade and human rights to an extent unparalleled in the culturally disparate and near-unmanageable, 150-plus member WTO itself. These new provisions have used tradeās huge power to improve worker rights, secure environmental protections, and make initial inroads toward defending indigenous populations from tradeās adverse effects. Employing the perspectives both of trade negotiators and students of this halting progress toward the integration of trade and human rights, we have concluded that the single greatest barrier to engaging in regional trade agreements (āRTAsā) openly and unequivocally to reduce global poverty through human rights implementation is the near-impenetrable complexity of human rights norms

The Effects of Water Ice Sublimation on Slope Failures of Icy Regolith
The frost line in a planetary system represents the distance from the central star inside of which conditions are too warm for ice to form, while beyond this line it will be stable. When an icy object passes that line heading toward the Sun it will begin to sublimate and outgas, potentially causing mass loss and surface changes. One example is surface failures, which can lead to material being removed from the object. Evidence of this has been seen on cometary surfaces, where surfaces often show structures that appear to have suffered various mechanical failures like cracking and landslides. By mixing water ice with sand and using a vacuum chamber to simulate the vacuum conditions of space, we monitored what happened as sublimation caused an evolution of the ice-sand mixture. Failures in the sample were observed from the top and the side by watching time-lapse videos of over 24 hour period created during the experiment run. We observed that the samples with more total material tended to show more activity and that samples with higher water concentrations continued to show āErosionā features for a longer period of time. Additionally, these higher water concentration samples showed larger failure features later in the runs, when the sample strength was much lower. While these were proof-of-concept experiments, the dependencies and observational notes may be applied to the interpretation of observations of comets in the Solar System
Co-production in practice : how people with assisted living needs can help design and evolve technologies and services
Background
The low uptake of telecare and telehealth services by older people may be explained by the limited involvement of users in the design. If the ambition of ācare closer to homeā is to be realised, then industry, health and social care providers must evolve ways to work with older people to co-produce useful and useable solutions.
Method
We conducted 10 co-design workshops with users of telehealth and telecare, their carers, service providers and technology suppliers. Using vignettes developed from in-depth ethnographic case studies, we explored participantsā perspectives on the design features of technologies and services to enable and facilitate the co-production of new care solutions. Workshop discussions were audio recorded, transcribed and analysed thematically.
Results
Analysis revealed four main themes. First, there is a need to raise awareness and provide information to potential users of assisted living technologies (ALTs). Second, technologies must be highly customisable and adaptable to accommodate the multiple and changing needs of different users. Third, the service must align closely with the individualās wider social support network. Finally, the service must support a high degree of information sharing and coordination.
Conclusions
The case vignettes within inclusive and democratic co-design workshops provided a powerful means for ALT users and their carers to contribute, along with other stakeholders, to technology and service design. The workshops identified a need to focus attention on supporting the social processes that facilitate the collective efforts of formal and informal care networks in ALT delivery and use
Desperately seeking intersectionality in digital health disparity research: narrative review to inform a richer theorization of multiple disadvantage.
Background:
Digital consultations between patients and clinicians increased markedly during the COVID-19 pandemic, raising questions about equity.
Objective:
This study aimed to review the literature on how multiple disadvantageāspecifically, older age, lower socioeconomic status, and limited English proficiencyāhas been conceptualized, theorized, and studied empirically in relation to digital consultations. We focused mainly on video consultations as they have wider disparities than telephone consultations and relevant data on e-consultations are sparse.
Methods:
Using keyword and snowball searching, we identified relevant papers published between 2012 and 2022 using Ovid MEDLINE, Web of Science, Google Scholar, and PubMed. The first search was completed in July 2022. Papers meeting the inclusion criteria were analyzed thematically and summarized, and their key findings were tabulated using the Grading of Recommendations Assessment, Development, and Evaluation Confidence in the Evidence from Reviews of Qualitative Research criteria. Explanations for digital disparities were critically examined, and a search was undertaken in October 2022 to identify theoretical lenses on multiple disadvantage.
Results:
Of 663 articles from the initial search, 27 (4.1%) met our inclusion criteria. In total, 37% (10/27) were commentaries, and 63% (17/27) were peer-reviewed empirical studies (11/27, 41% quantitative; 5/27, 19% qualitative; 1/27, 4% mixed methods; 1/27, 4% systematic reviews; and 1/27, 4% narrative reviews). Empirical studies were mostly small, rapidly conducted, and briefly reported. Most studies (25/27, 93%) identified marked digital disparities but lacked a strong theoretical lens. Proposed solutions focused on identifying and removing barriers, but the authors generally overlooked the pervasive impact of multiple layers of disadvantage. The data set included no theoretically informed studies that examined how different dimensions of disadvantage combined to affect digital health disparities. In our subsequent search, we identified 3 theoretical approaches that might help account for these digital disparities. Fundamental cause theory by Link and Phelan addresses why the association between socioeconomic status and health is pervasive and persists over time. Digital capital theory by Ragnedda and Ruiu explains how people mobilize resources to participate in digitally mediated activities and services. Intersectionality theory by Crenshaw states that systems of oppression are inherently bound together, creating singular social experiences for people who bear the force of multiple adverse social structures.
Conclusions:
A limitation of our initial sample was the sparse and undertheorized nature of the primary literature. The lack of attention to how digital health disparities emerge and play out both within and across categories of disadvantage means that solutions proposed to date may be oversimplistic and insufficient. Theories of multiple disadvantage have bearing on digital health, and there may be others of relevance besides those discussed in this paper. We call for greater interdisciplinary dialogue between theoretical research on multiple disadvantage and empirical studies on digital health disparities
Polyproline is a minimal antifreeze protein mimetic and enhances the cryopreservation of cell monolayers
Tissue engineering, gene therapy, drug screening and emerging regenerative medicine therapies are fundamentally reliant on high-quality adherent cell culture, but current methods to cryopreserve cells in this format can give low cell yields and requires large volumes of solvent 'antifreezes'. Herein we report polyproline is a minimum (bio)synthetic mimic of antifreeze proteins, which is accessible by solution, solid phase and recombinant methods. We demonstrate that polyproline has ice recrystallization inhibition activity linked to its amphipathic helix and that it enhances the DMSO- cryopreservation of adherent cell lines. Polyproline may be a versatile additive in the emerging field of macromolecular cryoprotectants
Comparative Analysis on Interpolation Methods for Bathymetric Data Gaps
Light Detection and Ranging (LIDAR) technology delivers high accuracy elevation values and ground features. However, the capability of this technology is inhibited in terms of its strength to penetrate certain surfaces. For instance, LIDAR is limited to the elevation values of the river water surface and not the elevation of its riverbed. Hence, topographic and bathymetric surveys are conducted to obtain an accurate set of elevation values for areas where the technology is unable to permeate. Bathymetric surveys are conducted using a scientific echo sounder equipment, which utilizes sonar technology to determine the river depth relative to the waterās surface by transmitting sound pulses and calculating the interval between the emanation and regress of a pulse per unit time. Like in all remote sensing measurements, errors are inevitable. Noise and external factors that cause faulty or bad readings result in data gaps. Gaps in the gathered elevation data sets can only be identified during filtering, which is done after the actual survey. In addition, covering the gaps back in the field would mean additional costs. This study aims to maximize data gathered by using different interpolation methods to generate points in the data gaps. Inverse Distance Weighting (IDW), Spline, and Kriging methods are used to extrapolate the values within the gaps. These values are then used together with the rest of the data for bathymetric data integration into the LIDAR data using IDW. Statistical calculations are shown to analyze the accuracy and efficiency of the results.

Designing assisted living technologies 'in the wild' : preliminary experiences with cultural probe methodology
Background
There is growing interest in assisted living technologies to support independence at home. Such technologies should ideally be designed āin the wildā i.e. taking account of how real people live in real homes and communities. The ATHENE (Assistive Technologies for Healthy Living in Elders: Needs Assessment by Ethnography) project seeks to illuminate the living needs of older people and facilitate the co-production with older people of technologies and services. This paper describes the development of a cultural probe tool produced as part of the ATHENE project and how it was used to support home visit interviews with elders with a range of ethnic and social backgrounds, family circumstances, health conditions and assisted living needs.
Method
Thirty one people aged 60 to 98 were visited in their homes on three occasions. Following an initial interview, participants were given a set of cultural probe materials, including a digital camera and the āHome and Life Scrapbookā to complete in their own time for one week. Activities within the Home and Life Scrapbook included maps (indicating their relationships to people, places and objects), lists (e.g. likes, dislikes, things they were concerned about, things they were comfortable with), wishes (things they wanted to change or improve), body outline (indicating symptoms or impairments), home plan (room layouts of their homes to indicate spaces and objects used) and a diary. After one week, the researcher and participant reviewed any digital photos taken and the content of the Home and Life Scrapbook as part of the home visit interview.
Findings
The cultural probe facilitated collection of visual, narrative and material data by older people, and appeared to generate high levels of engagement from some participants. However, others used the probe minimally or not at all for various reasons including limited literacy, physical problems (e.g. holding a pen), lack of time or energy, limited emotional or psychological resources, life events, and acute illness. Discussions between researchers and participants about the materials collected (and sometimes about what had prevented them completing the tasks) helped elicit further information relevant to assisted living technology design. The probe materials were particularly helpful when having conversations with non-English speaking participants through an interpreter.
Conclusions
Cultural probe methods can help build a rich picture of the lives and experiences of older people to facilitate the co-production of assisted living technologies. But their application may be constrained by the participantās physical, mental and emotional capacity. They are most effective when used as a tool to facilitate communication and development of a deeper understanding of older peopleās needs
Theorising the shift to video consulting in the UK during the COVID-19 pandemic: Analysis of a mixed methods study using practice theory
We studied video consulting in the National Health Service during 2020-2021 through video interviews, an online survey and online discussions with people who had provided and participated in such consultations. Video consulting had previously been used for selected groups in limited settings in the UK. The pandemic created a seismic shift in the context for remote consulting, in which video transformed from a niche technology typically introduced by individual clinicians committed to innovation and quality improvement to offering what many felt was the only safe way to deliver certain types of healthcare. A new practice emerged: a co-constitution of technology and healthcare made possible by new configurations of equipment, connectivity and physical spaces. Despite heterogeneous service settings and previous experiences of video consulting, we found certain kinds of common changes had made video consulting possible. We used practice theory to analyse these changes, interpreting the commonalities found in our data as changes in purpose, material arrangements and a relaxing of rules about security, confidentiality and location of consultations. The practice of video consulting was equivocal. Accounts of, and preferences for, video consulting varied as did the extent to which it was sustained after initial take-up. People made sense of video consulting in different ways, ranging from interpreting video as offering a new modality of healthcare for the future to a sub-optimal, temporary alternative to in-person care. Despite these variations, video consulting became a recognisable social phenomenon, albeit neither universally adopted nor consistently sustained. The nature of this social change offers new perspectives on processes of implementation and spread and scale-up. Our findings have important implications for the future of video consulting. We emphasise the necessity for viable material arrangements and a continued shared interpretation of the meaning of video consulting for the practice to continue
