Exploration of family caregivers’ experiences on coping in dementia care in Ghana: a phenomenological study

BackgroundDementia is an important public health and geriatric concern for sub-Saharan African countries, including Ghana. Evidence shows that persons living with dementia are often supported and cared for by family caregivers in the community. In the execution of these services to the persons living with dementia, family caregivers are overwhelmed and experience heightened stress that results in serious repercussions. Therefore, the aim of this study was to explore family caregivers’ experiences on coping in dementia care in Ghana.MethodsAdopting a descriptive phenomenological design, individual face-to-face interviews were conducted among thirty unpaid family caregivers of persons living with dementia in Ghana. Semi-structured interview guides were used. The data analysis process followed Clarke and Braun’s framework analysis.ResultsSix themes were generated from the textual data. These themes were captioned as: (1) empathy and perspective-taking; (2) family support and cohesion; (3) coaxing and pampering of persons living with dementia; (4) humour and positive communication; (5) spiritual support; and (6) ethical/moral consideration in dementia caregiving.ConclusionWe conclude that unpaid family caregivers of persons living with dementia in Ghana adopt varied strategies to cope with the strains of caregiving. Healthcare facilities that provide services to persons living with dementia could incorporate caregiver preparatory training or education for family caregivers. This training should focus on briefing family caregivers about the potential strains that they are likely to encounter. Also, the training could focus on equipping family caregivers with the knowledge and skills to effectively communicate and care for the persons living with dementia using person-centered approaches. Key stakeholders such as the Ghana Health Service and Alzheimer’s Ghana must raise awareness about the dangers of caregivers’ violation of the autonomy and freedom of persons living with dementia as they navigate through the challenges of caregiving. Lastly, faith-based institutions need to be considered as key stakeholders in dementia interventions since they could play a critical role.

A GA based SVM-Bayesian technique and its application in process monitoring for mixed distributed data

Traditional data-driven fault diagnosis methods, such as principal component analysis (PCA) and independent component analysis (ICA), have significantly improved condition monitoring and fault diagnosis of industrial process by analyzing process data. However, their accuracy is limited due to the assumption that the data follows Gaussian or non-Gaussian distribution, respectively. In reality, process data is often a mixture of both Gaussian and non-Gaussian distributions, leading to reduced accuracy of the training model and fault diagnosis results. To address this issue, a genetic algorithm-based SVM-Bayesian (GSB) scheme is proposed in this paper for feature combination and model integration. The scheme first employs ICA and PCA to extract the independent/principal components of the original data, and then constructs the corresponding fault features for SVM training to obtain basic models. The extraction of fault features are optimized using genetic algorithms based on defined accuracy and diversity functions. During online monitoring, the final diagnosis result is obtained by combining the results of the basic models through Bayesian inference. The effectiveness of the proposed scheme is evaluated using a numerical example and a case study of the Tennessee Eastman process. The results show that the accuracy of fault classification is improved by about 5% compared with traditional methods.

Structural violence and necropolitics among Indigenous Peoples living with HIV who use substances in the Prairie provinces during COVID-19

BackgroundWithin Manitoba and Saskatchewan, pre-existing health inequities amongst Indigenous groups were intensified during the COVID-19 pandemic. Service disruptions in the health and social service sector—combined with the effects of intersectional stigma—disproportionately impacted Indigenous peoples living with HIV (IPLH). IPLH experience structural violence and necropolitical exclusion through systemic forms of stigma situated within Canada's expansive colonial history. Utilizing the theoretical foundations of structural violence and necropolitics, this qualitative study examines how the COVID-19 pandemic amplified preceding states of inequity for IPLH. MethodsSemi-structured interviews were conducted with 60 participants. The sample comprised of those with lived experience (n = 45) as well as those who provided services for IPLH (n = 15). Indigenous Storywork guided the data collection and analysis process. Topics explored within each interview included access to health and social services, harm reduction, substance use, and experiences in providing services during COVID-19 pandemic. Thematic analysis was used to identify common themes throughout each story. ResultsOur results indicate that the COVID-19 pandemic exposed and amplified pre-existing forms of structural violence and necropolitical logics for IPLH within Manitoba and Saskatchewan. Specifically, we describe how structural violence and necropolitics are manifested via three main avenues— (i) restrictions and removal of care, (ii) bureaucracy and institutional care politics, and (iii) discrimination and systemic racism within the Canadian healthcare system. ConclusionThe COVID-19 pandemic within Manitoba and Saskatchewan sparked massive changes in service provision within settler-colonial and neoliberal institutions of care. For those services that remained open to IPLH, masking requirements, questionnaire requirements, scheduling requirements, and a lack of in-person services acted as only some of the barriers described by community members as detrimental to care access. Increased experiences of discrimination in health care on the basis of substance use or HIV status further limited access to needed services.

Characterize direct protein interactions with enrichable, cleavable and latent bioreactive unnatural amino acids

Latent bioreactive unnatural amino acids (Uaas) have been widely used in the development of covalent drugs and identification of protein interactors, such as proteins, DNA, RNA and carbohydrates. However, it is challenging to perform high-throughput identification of Uaa cross-linking products due to the complexities of protein samples and the data analysis processes. Enrichable Uaas can effectively reduce the complexities of protein samples and simplify data analysis, but few cross-linked peptides were identified from mammalian cell samples with these Uaas. Here we develop an enrichable and multiple amino acids reactive Uaa, eFSY, and demonstrate that eFSY is MS cleavable when eFSY-Lys and eFSY-His are the cross-linking products. An identification software, AixUaa is developed to decipher eFSY mass cleavable data. We systematically identify direct interactomes of Thioredoxin 1 (Trx1) and Selenoprotein M (SELM) with eFSY and AixUaa.

Elaboration of Underpinning Methods and Data Analysis Process of Directed Qualitative Content Analysis for Communication Studies

Directed qualitative content analysis (QCA) is a qualitative analysis method that has been recently explained and employed practically by a few researchers at the international level. They employed it deductively in most cases, primarily within qualitative research guidelines. In contrast to the inductive method, which starts with a general hypothesis and builds upon it as it gathers data, the deductive method, also known as the directed approach, researchers develop the categories and subcategories that guide their research based on an already established theory or theories. The present paper also explained this conceptual method in the context of the deductive approach. The purpose of deductive or directed QCA is to test, verify, or broaden the scope of the study’s underlying theory(s) by applying them to data collected from sources other than those directly relevant to its creation. Researchers employed deductive QCA in sixteen and seven steps in previous studies, respectively. Hence, this article proposes a four-step conceptual model deduced from the present researchers’ previous works and others’ previous studies to address the gaps above in the qualitative research tradition and achieve the same goals with the research data. We provide conceptual sample data in tables as examples for scholars interested in political communication who might use DQCA in their future studies.
