Perspectives of minority ethnic caregivers of people with dementia interviewed as part of the IDEAL programme

YesPostwar migrants from the Caribbean and Indian subcontinent (Bangladesh, India, and Pakistan) to the UK are now experiencing the onset of age-related diseases such as dementia. Our evidence base, both quantitative and qualitative, documenting the experiences of family caregivers of people with dementia is largely drawn from studies undertaken with white European, North American, and Australasian populations. Consequently, there is a need for research in the field of dementia caregiving to reflect the increasing diversity in ethnic identities of the older adult population of the UK. Using semistructured interviews, we investigated the experiences of 18 caregivers of people with dementia in Black Caribbean, Black African, and South Asian (Indian, Pakistani, and Bangladeshi) communities in England. Participants were recruited from the Join Dementia Research platform and were predominantly female intergenerational carers. We identified the following three themes: motivation to care (spending time with the care recipient and reciprocity), positive and negative consequences of caregiving (rewards and consequences), and the cultural context of caregiving (cultural norms and values supporting caregiving and negative attitudes towards dementia). Our findings develop existing literature by identifying (a) the importance of spending time with the person they care for, (b) the absence of faith as a caregiving driver, and (c) the challenge of watching the declining health of a parent. We highlight how the different motivations to care are intertwined and dynamic. This is illustrated by the linking of obligation and reciprocity in our dataset and positive and negative experiences of caregiving.Alzheimer's Society. Grant Numbers: 348, AS-PR2-16-001.

Reminiscence respecified: A conversation analytic examination of practice in a specialist dementia care home

YesAlthough discussion of reminiscence is prevalent in dementia care research, few studies have examined what actually occurs in these interactions, and how they are structured. This study examined how reminiscence activities are structured and negotiated in a care home environment. Informal one-to-one reminiscence interactions between people living with dementia and professional carers were transcribed from a larger video dataset. We used Conversation Analysis to examine reminiscence sequences in a novel relational approach that explored the interactional practices used by carers and people living with dementia. We identified divergences between manualised practice recommendations and observed interactional practices, such as the rarity of open questions, and frequent use of closed questions. This was contrary to current practice recommendations. These and other divergences demonstrate the value of interactional research in informing reminiscence practice and training manuals. By examining how reminiscence operates in practice, our approaches to conducting such activities can be more empirically informed. Our findings can be used to advise and guide those doing reminiscence work in care home settings, and improve the inclusiveness of reminiscence interactions. Through incorporating empirically informed techniques that both carers and people with dementia use in practice, we can facilitate interactions around memories which are supportive of people with dementia's identity.This research was supported by an ESRC doctoral studentship funded through the Midlands Graduate School DTP [ES/P099711/1] and Loughborough University.

Enhancing design and performance analysis of satellite EB/CV-QKD/FSO systems

YesSatellite QKD/FSO systems, which facilitate quantum key distribution (QKD) over free-space optical (FSO) links between satellites and ground stations, present a promising pathway toward achieving global security in upcoming sixth-generation (6G) wireless communications. Our study focuses on a superior type of these systems, the satellite EB/CV-QKD/FSO, which utilizes the continuous-variable (CV) method for quantum state representation and the entanglement-based (EB) scheme for QKD implementation. We propose the use of optical phase-shift keying (QPSK) signaling and dual-threshold/heterodyne detection (DT/HD) receivers to bolster the reliability and feasibility of satellite EB/CV-QKD/FSO systems. Closed-form expressions for key system performance metrics are derived using improved channel modeling. Numerical results are presented to showcase the effects of channel impairments on the system performance. We also provide recommendations for optimal system setup parameters, aiming to enhance performance.Ministry of Information and Communications (Vietnam) (Grant Number: DT.26/23).

APOE genotype, eicosapentaenoic acid (EPA) supplementation and n-3 highly unsaturated fatty acid (HUFA) levels in patients with multiple colorectal polyps: A secondary analysis of the seAFOod polyp prevention trial

YesIntroduction: We examined the relationship between Apolipoprotein E (APOE) genotype and n-3 highly unsaturated fatty acid (HUFA) levels in participants of the seAFOod trial, who were undergoing colonoscopy surveillance after removal of colorectal polyps. Methods: Baseline and on-treatment (eicosapentaenoic acid [EPA] 2 g daily or placebo for 6 months) levels of n-3 HUFAs, and plasma 18-hydroxyeicosapentaenoic acid (HEPE), were analysed according to APOE genotype (based on polymorphisms rs429358 and rs7412) in 584 participants. Results: Before treatment, APOE2/2 individuals had lower levels, and APOE4/4 participants had higher levels, of n-3 HUFAs, including EPA, than APOE3/3 counterparts (P < 0.01 for the APOE2/2 versus APOE4/4 comparison). After EPA supplementation, n-3 HUFA levels were not significantly different when stratified by APOE genotype, although APOE4 carriers displayed lower plasma 18-HEPE levels than individuals without an APOE4 allele (P = 0.002). Conclusions: APOE genotype is associated with differential n-3 HUFA and 18-HEPE levels in individuals with multiple colorectal polyps.This project (NIHR128210) was funded by the Efficacy and Mechanism Evaluation (EME) Programme, an MRC and NIHR partnership.

Acquisition time in laser inter-satellite link under satellite vibrations

YesPointing, acquisition, and tracking (PAT) is a major technical challenge of laser inter-satellite links (ISLs). For the fast establishment of laser link and the maximization of communication time, it is of importance to minimize the acquisition time. Satellite vibrations affect the PAT procedure adversely, and thus serve to increase the acquisition time. In this paper, we investigate through theoretical analysis the average acquisition time of laser ISLs in the presence of satellite vibrations. The analytic expression about the time taken from the beginning of spiral scan to the acquisition of the scan beam is provided in the presence of the pointing errors caused by vibrations. We also derive the optimum beam divergence angle for the acquisition time. The analyses are validated by Monte-Carlo computer simulations and a proof-of-concept experiment. The results show that the acquisition time can be minimized by adjusting the beam divergence angle adaptively to the link conditions.Grant-in-aid of Hanwha System

Food expenditure, income, and mental health: outcomes from the UK Household Longitudinal Survey

YesThe incidence of mental health problems is increasing in the United Kingdom and may be associated with lower dietary quality. Food expenditure is a marker of food insecurity with potential implications for mental health. This analysis considers data collected as part of the United Kingdom Household Longitudinal Survey (UKHLS), also known as ‘Understanding Society’ (2009-2021) (N=388,944) to determine the extent to which food expenditure within and outside the household, is associated with mental health, whilst controlling for demographic factors. Mental health was measured using the General Health Questionnaire (GHQ-12) for which responses were on a 4-point scale and reverse-scored so that a higher score represented more favourable mental health. Household food expenditure and food expenditure outside the home were the outcomes. Controlling for socioeconomic and demographic factors, fixed-effects models indicated that better mental health was associated with greater household food expenditure and with greater food expenditure outside the home and that this association persisted post-lockdown. Among those on lower incomes better mental health was associated with lower food expenditure. When people who identified as white and non-white were modelled separately, better mental health was associated with lower food expenditure within and beyond the household only in those who identified as white. These findings imply that the mental health of people residing in the UK, particularly those on lower incomes and those who identify as white, may benefit from spending less of the household budget on food. In achieving United Nations General Assembly (2012) Sustainable Development Goals related to poverty, hunger and in promoting mental health, policies are needed to render food more affordable and to reduce other aspects of expenditure that impact upon food budgeting

“We don’t know who be who”: post-party politics, forum shopping and Liberia’s 2017 elections

YesLiberia’s 2017 elections represented a watershed moment in the country’s political history. In addition to completing the first democratic transfer of power from one president to another since 1944, it resulted in wide representation across many different parties and independents as well as high levels of legislative turn-overs. Additionally, these polls brought forward unprecedented numbers of party reconfigurations, increased levels of defections, and politicians/parties losing abysmally in presumed ethno-regional bases. In this article, we argue that Liberia currently exists in a post-war arena of “post-party” politics where a profound disregard for parties is the norm, and in which the electorate and politicians alike forum shop for candidates and/or political configurations they presume will deliver the best results at national, sub-national and local levels. Although literature exploring electoral trends in Africa tends to over-emphasize ethno-regionalism as a driver and constraint in the choices of voters and politicians, we demonstrate instead that Liberians make relatively informed, strategic decisions about political alliances and ballot casting thereby subverting allegiances to ethnicity and region. By further eschewing party loyalties, Liberians have gradually become astute forum shoppers in a political marketplace that makes running for office and voting complex undertakings

Power-informed practice in social work

YesSummary: This article reviews the existing literature on power within a social work context and extends the analysis to broader sociological understandings through which to rethink the ways in which social work professionals understand and work with power within everyday practice. Findings: The review argues that prevailing dichotomies, which feature so centrally in theoretical conceptualisations of power, offering binary positions of power as ‘good or bad’, ‘positive or negative’ and ‘productive or limiting’ are limiting in themselves. It is argued that power must also be recognised as a construct which operates in a synchronous way; whereby it can impact in limiting and productive ways at the same time. Applications: To support this position, the Power-informed Practice (PiP) framework, which recognises power at the individual, professional and structural levels is offered. The utility of the framework in providing a clearer understanding of power is then presented in relation to working with children who have experienced abuse. As a tool, the framework enables social workers to structure their analysis of power within all areas of contemporary social work practice, in order to promote and support processes of empowerment

Self-healing properties of mortar with crystalline admixture: experimental investigation and parameter optimization

YesThe inclusion of crystalline admixture (CA) is a highly effective method for enhancing the self-repairing capabilities of mortar. This study examined the complexing abilities of different complexing agents under varying temperatures, pH levels, and ion species in order to select effective complexing agents for diverse environments, as complexing agents play a crucial role in CAs. After determining the type of complexing agent, an orthogonal array design was used to optimize the components of CA, and the strengthening mechanism of CA for mortar was discussed through microstructure analysis. The results showed that the complexation behavior of triethanolamine (TEA) and glycine performed better than sodium citrate (SC) for different pH, temperatures, and ion species. Meanwhile, TEA and glycine showed complementarity at different stages, so TEA and glycine were used as complexing agents in this study. Based on the orthogonal experiment, the optimal contents of Na2SiO3, Na2CO3, TEA, glycine, Ca(COOH)2, and nano-SiO2 in CA were determined to be 1.0%, 1.0%, 0.04%, 1.0%, 0.5%, and 1.0%, respectively. Under the synergistic effect of TEA and glycine, the hydration of aluminate and ferrialuminate was accelerated, and the hydration degree of cement paste was increased. At 28 d, the contents of CaCO3, C-S-H gel, and ettringite of cement paste with CA were higher than these of plain paste, but its Ca(OH)2 content was lower. Although the Ca(OH)2 content in the cement paste with CA was lower, the Ca(OH)2 crystal structure filled in the pores was larger. Therefore, the mortar mixed with CA exhibited higher compressive strength, water impermeability, and self-healing ability.The full-text of this article will be released for public view at the end of the publisher embargo on 3 May 2025

Green missing spots: Information entropy on greenhouse gas emission disclosure by Brazilian companies

YesThis study aims to address a critical gap in the literature by examining the incorporation of uncertainty in measuring carbon emissions using the greenhouse gas (GHG) Protocol methodology across all three scopes. By comprehensively considering the various dimensions of CO2 emissions within the context of organizational activities, our research contributes significantly to the existing body of knowledge. We address challenges such as data quality issues and a high prevalence of missing values by using information entropy, techniques for order preference by similarity to ideal solution (TOPSIS), and an artificial neural network (ANN) to analyze the contextual variables. Our findings, derived from the data sample of 56 companies across 18 sectors and 13 Brazilian states between 2017 and 2019, reveal that Scope 3 emissions exhibit the highest levels of information entropy. Additionally, we highlight the pivotal role of public policies in enhancing the availability of GHG emissions data, which, in turn, positively impacts policy-making practices. By demonstrating the potential for a virtuous cycle between improved information availability and enhanced policy outcomes, our research underscores the importance of addressing uncertainty in carbon emissions measurement for advancing effective climate change mitigation strategies.The full-text of this article will be released for public view at the end of the publisher embargo on 3 Aug 2025
