RESUMO

Aiming at real-time detection of UAVs, small UAV targets are easily missed and difficult to detect in complex backgrounds. To maintain high detection performance while reducing memory and computational costs, this paper proposes the SEB-YOLOv8s detection method. Firstly, the YOLOv8 network structure is reconstructed using SPD-Conv to reduce the computational burden and accelerate the processing speed while retaining more shallow features of small targets. Secondly, we design the AttC2f module and replace the C2f module in the backbone of YOLOv8s with it, enhancing the model's ability to obtain accurate information and enriching the extracted relevant information. Finally, Bi-Level Routing Attention is introduced to optimize the Neck part of the network, reducing the model's attention to interfering information and filtering it out. The experimental results show that the mAP50 of the proposed method reaches 90.5% and the accuracy reaches 95.9%, which are improvements of 2.2% and 1.9%, respectively, compared with the original model. The mAP50-95 is improved by 2.7%, and the model's occupied memory size only increases by 2.5 MB, effectively achieving high-accuracy real-time detection with low memory consumption.

RESUMO

PURPOSE: High costs of applying to genetic counseling graduate programs (GCGPs) are likely a barrier to workforce diversification. We sought to determine application costs and assess differences between individuals of historically underrepresented racial and ethnic backgrounds in medicine (hURM) and non-hURM applicants. METHODS: Applicants to GCGPs between 2005-2020 were surveyed about application history, related expenses, volunteer hours, and financial resources; 383 responses were analyzed. RESULTS: Median total application costs (MTAC) were $2,634, $4,762, and $5,607 (one, two, and three or more application cycles, respectively). Interview-related items (which includes travel) had the highest median cost (one application cycle: $879). Among those who applied to multiple cycles, hURM respondents had higher MTAC than those of non-hURM ($6,713 versus $4,762, p=0.03) and lower median total volunteer hours (246 versus 381, p=0.03). Parental education level differed by hURM status (p=0.04). Median financial contribution from parents with and without advanced degrees varied significantly (60% vs 2%, p=0.0009). CONCLUSION: Significant costs are incurred during the GCGP application process, but notable differences in costs and resources were observed between hURM and non-hURM applicants. Stakeholders within the profession should implement strategies to reduce financial barriers and the resulting inequities in the application process.

RESUMO

Background: The question of what brings someone to homelessness and keeps them there has many varied and complex answers. The authors believe the answers lie within the persons experiencing homelessness (PEH). Methods: This is an interpretive approach study based on convenience sampling of the San Antonio, TX, unsheltered population, utilizing semi-structured interviews from January 2022 through November 2022. Results: The six most common themes that emerged from the subjects' backgrounds were 1) jail or prison time or other personally significant legal issues; 2) personal substance abuse or addiction struggles; 3) physical and mental health challenges as an adult; 4) disdain of shelters and preference for rough sleeping; 5) a problematic childhood; 6) did not enjoy school as a child or young adult. Conclusion: To gain more insight into a situation as complex as the state of homelessness, researchers should meet with those on the frontline of this epidemic and hear first-hand their personal histories, challenges, successes, and suggestions. Though not a novel approach, the researchers found limited previous literature in regard to approach, scope and in relation of causation related to homelessness, especially about the U.S. unsheltered population. The ultimate goal is for such research to help guide outreach services and legislation related to PEH.

RESUMO

We developed a novel quadratic resampling method for summing up γ-ray spectra with different calibration parameters. We investigated a long-term environmental background γ-ray spectrum by summing up 114 spectra measured using a 30% HPGe detector between 2017 and 2021. Gain variations in different measurement periods shift γ-ray peak positions by a fractional pulse-height bin size up to around 2 keV. The resampling method was applied to measure low-level background γ-ray peaks in the γ-ray spectrum in a wide energy range from 50 keV to 3 MeV. We additionally document temporal variations in the activities of major γ-ray peaks, such as 40K (1461 keV), 208Tl (2615 keV), and other typical nuclides, along with contributions from cosmic rays. The normal distribution of γ-ray background count rates, as evidenced by quantile-quantile plots, indicates consistent data collection throughout the measurement period. Consequently, we assert that the quadratic resampling method for accumulating γ-ray spectra surpasses the linear method (Bossew, 2005) in various aspects.

RESUMO

Background: While cultural backgrounds are well-documented to be relevant to intentional self-harm, little is known about how cultural and linguistically diverse (CALD) backgrounds affect mortality outcomes following self-harm. Aim: This study aimed to compare the risk of all-cause mortality and suicide after intentional hospital admissions for self-harm among people from CALD (vs. non-CALD) backgrounds. Method: Linked hospital and mortality data in Victoria, Australia, was used to assess suicide and all-cause death after hospital admissions for self-harm among patients aged 15+ years. All-cause death was identified by following up on 42,122 self-harm patients (hospitalized between 01 July 2007 and 30 June 2019) until death or 15 February 2021. Suicide death was evaluated in 16,928 self-harm inpatients (01 January 2013 and 31 December 2017) until death or 28 March 2018. Cox regression models were fitted to compare mortality outcomes in self-harm patients from CALD vs. non-CALD backgrounds. Outcomes: During the follow-up periods, 3,716 of 42,122 (8.8%) participants died by any cause (by 15 February 2021), and 304 of 16,928 (1.8%) people died by suicide (by 28 March 2018). Compared to the non-CALD group, CALD intentional self-harm inpatients had a 20% lower risk of all-cause mortality (HR: 0.8, 95% CI: 0.7-0.9) and a 30% lower risk of suicide (HR: 0.7, 95% CI: 049-0.97). Specifically, being from North Africa/Middle East and Asian backgrounds lowered the all-cause mortality risk; however, the suicide risk in Asians was as high as in non-CALD people. Conclusion: Overall, people from CALD backgrounds exhibited lower risks of all-cause mortality and suicide following hospital admission for self-harm compared to the non-CALD group. However, when comparing risks based on regions of birth, significant variations were observed. These findings underscore the importance of implementing culturally tailored background-specific suicide preventive actions. The study focussed on outcomes following hospital admission for self-harm and did not capture outcomes for cases of self-harm that did not result in hospital admission. This limits generalisability, as some CALD people might avoid accessing healthcare after self-harm due to cultural factors. Future research that not limited to hospital data is suggested to build on the results.

RESUMO

OBJECTIVES: Drawing on findings from a qualitative study that aimed to explore the knowledge and attitudes of nurses from culturally and linguistically diverse (CALD) backgrounds about voluntary assisted dying (VAD). The study also aimed to identify the strategies that assist nurses in their readiness and preparation for exposure to VAD. This paper reports on the educational content and strategies that could assist nurses from CALD backgrounds to be better prepared when they encounter VAD requests. BACKGROUND: Around the world, healthcare professionals have roles to play in caring for patients requesting voluntary assisted dying. Nurses, particularly those from diverse geographic and clinical settings, have voiced inadequate knowledge and understanding about voluntary assisted dying. DESIGN: A qualitative descriptive approach was undertaken. METHODS: Data collection involved one focus group and 16 in-depth interviews. A total of 21 nurses from CALD backgrounds were recruited from one Australian state. Thematic analysis was conducted to interpret the data. FINDINGS: Nurses identified their knowledge gaps and specified the need for education and workplace training on VAD, its legal and ethical aspects, clarity on their role, communication techniques and how VAD intersects with their practice. They suggested various teaching strategies that could prepare nurses to work safely and confidently in a clinical environment where voluntary assisted dying is an option for patients. CONCLUSION: Given the high number of nurses from diverse backgrounds working in the Australian health sector, these nurses need to be fully prepared to care for patients requesting VAD.

RESUMO

Our study aimed to establish the prevalence of adolescent young carers (AYCs) among 11-15-year-old French adolescents and explore the impacts of caring on these youths through a comprehensive evaluation of their quality of life. A total of 1983 middle school pupils (mean age = 12.89; 56.23% females) completed self-reported questionnaires evaluating their sociodemographic characteristics, illness/disability in their family, caring activities (MACA-YC18), quality of life (KIDSCREEN-52), perceived health, and academic performance. Descriptive analyses, Chi-square tests of independence, Student's t-tests, and analysis of variance and of covariance were conducted. The results showed that 12.25% of middle school pupils were AYCs. They were mostly females, coming from disadvantaged economic backgrounds. The ill/disabled relative was typically a parent, and 23.87% of respondents reported having more than one ill/disabled relative. The AYCs more often declared an illness or a disability and reported lower quality of life scores than their peers in several dimensions: Physical Well-Being, Psychological Well-Being, Moods and Emotions, Self-Perception, Autonomy, Relations with Parents and Home Life, Financial Resources, School Environment, Social Acceptance. No differences were identified in the Social Support and Peers dimension. Given the high prevalence of AYCs in middle schools and the impact of the situation on their lives, special support should be provided for AYCs, and professionals at school should be trained to better identify and assist AYCs.

RESUMO

BACKGROUND: In the context of China's innovation-driven economy, the competitive advantage for pharmaceutical companies increasingly depends on their level of innovation. The executives, as the highest decision-makers in the company, directly influence corporate research and development (R&D) investment and innovation performance. Additionally, government subsidies, as an external factor alleviating corporate financial constraints, also impact a company's R&D investment. According to a survey by the Journal of China Securities, at the end of 2020, among 119 pharmaceutical companies listed on the A-share market, only 53.3% had Chief Executive Officer (CEOs) with pharmaceutical backgrounds. This study constructs a theoretical model of executive pharmaceutical backgrounds, R&D investment, government subsidies, and corporate innovation performance in pharmaceutical companies, aiming to reveal the mechanism and boundary condition between executive pharmaceutical backgrounds and corporate innovation performance in the pharmaceutical industry. METHODS: This study uses Chinese pharmaceutical companies listed from 2015 to 2022 as the research sample. The selected sample was processed as follows: companies with significant issues and risks of Special Treatment (ST) or *ST were excluded, companies with missing data were excluded, and companies for which executive background data could not be obtained were excluded. After these exclusions, the study obtained data for 223 listed pharmaceutical companies over 8 years. Then we constructed a three-stage regression model to test the impact of executive pharmaceutical background on R&D investment, the impact of R&D investment on corporate innovation performance, and the mediating effect of R&D investment. Considering that some scholars raised questions about it, this study simultaneously uses the Bootstrap analysis method in the SPSS PROCESS to test the mediating effect of R&D and the moderated mediating effect of government subsidies. RESULTS: The empirical research results reveal that executive pharmaceutical backgrounds have a significant positive impact on corporate R&D investment. R&D investment contributes to the innovation performance of pharmaceutical companies and plays an intermediary role between executive pharmaceutical backgrounds and corporate innovation performance. Government subsidies act as a moderator in the relationship between executive pharmaceutical backgrounds and R&D investment, and they also moderate the mediating effect of executive pharmaceutical backgrounds, R&D investment, and corporate innovation performance. CONCLUSIONS: This study provides insight from a dual perspective of internal and external factors, revealing the internal mechanism and boundary conditions influencing the innovation performance of pharmaceutical companies. In conclusion, pharmaceutical companies should employ executives with pharmaceutical backgrounds to manage the company. This will help increase the company's R&D investment, subsequently improving R&D performance and enhancing the pharmaceutical company's innovation competitiveness. This study not only expands the theories in the fields of executive characteristics, R&D investment, and corporate innovation performance but also has important policy implications for the appointment and selection of executives in pharmaceutical companies.

RESUMO

A total of four populations of reciprocal backcross recombinant inbred lines were produced from a cross between a wild accession of Oryza rufipogon W630 and two major cultivars, O. sativa Japonica Nipponbare and Indica IR36. Using these populations, quantitative trait locus (QTL) analysis for eight morphological traits (culm length, panicle length, days to heading, panicle shape, pericarp color, hull color, seed shattering and seed awning) was carried out, and the putative QTL regions were compared among the populations. The QTLs with strong allele effects were commonly detected for culm length, panicle shape, pericarp color and hull color in all four populations, and their peak locations were close to the major genes of sd1, Spr3, Rc and Bh4, respectively. For panicle length and days to heading, some QTL regions overlapped between two or three populations. In the case of seed shattering and seed awning, strong wild allele effects at major loci were observed only in the populations with cultivated backgrounds. Since the wild and cultivated alleles have never been evaluated in the reciprocal genetic backgrounds, the present results provide new information on gene effects in breeding and domestication studies.

RESUMO

BACKGROUND: Primary health care [PHC] services with general practitioners (GPs) as the first point of access to health care services for people from refugee backgrounds in Australia can play a crucial role in building health literacy and promoting access to culturally appropriate services. To achieve equitable access and engagement, services and systems must be responsive to diverse health literacy and cultural needs. This study aims to explore how primary health services respond as a system and organisation to the health literacy and cultural needs of people from refugee backgrounds in Australia. METHODS: This exploratory qualitative study involved 52 semi-structured interviews among 19 Africans from refugee backgrounds, 14 service providers, including GPs and nurses, and 19 other stakeholders, such as service managers/directors. Participants resided in New South Wales, Victoria, and Queensland. Interviews were audio-recorded, transcribed, and coded into QSR NVivo 12. Data analysis was guided by reflexive thematic analysis. FINDINGS: Three interrelated themes were identified from the data relating to the health literacy and cultural responsiveness of PHC systems and services. The first theme, 'variable and ad hoc organisational response to health literacy and culturally responsive care,' demonstrated that some organisations did not systematically address the inherent complexity of navigating the health system nor the capacity of services and providers to respond to the cultural needs of people from refugee backgrounds. The second theme, 'individual provider responsibility,' captured the individual providers' interpersonal and relational efforts in supporting the health literacy and cultural needs of people from refugee backgrounds based on their motivation and adaptation. The third theme, 'refugee patient responsibility,' encapsulated people from refugee backgrounds' adaptations to and learning of the health system to navigate and access services. CONCLUSION: Health literacy and culturally responsive practices need to be systematised by PHC organisations to be implemented and sustained over time. There is a need for diversity in the organisational leadership and health care workforce, organisational commitment, health literacy and culturally responsive care policies, provider training, and auditing practice as essential components of the change process. Engaging with refugee communities would allow services to focus on people from refugee backgrounds' needs by design.

RESUMO

PURPOSE: Adjuvant chemotherapy is recommended following colorectal cancer resection based on risk of recurrence. In older patients, treatment decisions should consider recurrence rates and tolerability, as well as functional prognosis, residual disease, and social factors. This study aims to investigate factors, including social background, influencing implementation of postoperative adjuvant chemotherapy in older patients undergoing curative resection for colorectal cancer. METHODS: This multi-institutional prospective cohort study included 15 institutions belonging to the Hiroshima Surgical study group for Clinical Oncology. We analyzed 159 older patients aged ≥ 80 years, who underwent curative resection for stage III colorectal cancer between December 2013 and June 2018, as sub-analysis of the HiSCO-04 study. RESULTS: In total, 62 (39.0%) patients underwent postoperative adjuvant chemotherapy. Four factors were significantly associated with its implementation: performance status < 2, Charlson Comorbidity Index < 2, prognostic nutritional index ≥ 40, and presence of a spouse or siblings as lifestyle supporters. No significant difference was found in the backgrounds between complete and incomplete postoperative adjuvant chemotherapy patients. CONCLUSION: Performance status, Charlson Comorbidity Index, nutritional status, and presence of a spouse or siblings as lifestyle supporters are possible factors influencing the implementation of postoperative adjuvant chemotherapy in older patients. To select appropriate treatment options, including postoperative adjuvant chemotherapy, it is essential to consider physical condition and comorbidities of older patients, thoroughly explain the situation to their families, and establish a support system to enhance understanding of the available treatment options.

RESUMO

Porcine reproductive and respiratory syndrome virus (PRRSV) is a highly infectious and economically significant virus that causes respiratory and reproductive diseases in pigs. It results in reduced productivity and increased mortality in pigs, causing substantial economic losses in the industry. Understanding the factors affecting pig responses to PRRSV is crucial to develop effective control strategies. Genetic background has emerged as a significant determinant of susceptibility and resistance to PRRSV in pigs. This review provides an overview of the basic infection process of PRRSV in pigs, associated symptoms, underlying immune mechanisms, and roles of noncoding RNA and alternative splicing in PRRSV infection. Moreover, it emphasized breed-specific variations in these aspects that may have implications for individual treatment options.

RESUMO

In the context of carbon peaking and carbon-neutral target, enterprises need to adjust their resource allocation and practice environmental, social, and governance (ESG) activities. Previous literature ignores the resources and costs that enterprises may consume to improve ESG ratings, leading to an unclear relationship between ESG ratings and trade credit. We investigate how ESG ratings affect trade credit using the inverted U-shaped (U-shaped) moderating effect regression model. The result shows that ESG ratings have an inverted U-shaped relationship with trade credit. Information transparency moderates the curvilinear relationship between ESG ratings and trade credit, with higher information transparency flattening the shape of the inverted U-shaped curve and moving the inflection point to the left. Executives with overseas backgrounds significantly moderate the inverted U-shaped relationship between ESG ratings and trade credit. Executives with overseas backgrounds flatten the inverted U-shaped relationship, and the inflection point shifts to the right. Overall, our findings show that higher ESG ratings do not help enterprises to expand trade credit in emerging market countries. Higher ESG ratings consume more corporate resources and are more likely to become a tool for management self-interest.

RESUMO

PURPOSE: To examine the associations between Culturally and Linguistically Diverse backgrounds (vs non-Culturally and Linguistically Diverse) and in-hospital death due to self-harm, repeat self-harm and mental health service use after self-harm. METHOD: A retrospective study of 42,127 self-harm hospital inpatients aged 15+ years in Victoria, Australia, from July 2008 to June 2019. Linked hospital and mental health service data were used to assess in-hospital death, repeat self-harm and mental health service use in the 12 months following index self-harm hospital admission. Logistic regression and zero-inflated negative binomial regression models were used to estimate associations between cultural background and outcomes. RESULTS: Culturally and Linguistically Diverse people accounted for 13.3% of self-harm hospital inpatients. In-hospital death (0.8% of all patients) was negatively associated with Culturally and Linguistically Diverse background. Within 12 months, 12.9% of patients had self-harm readmission and 20.1% presented to emergency department with self-harm. Logistic regression components of zero-inflated negative binomial regression models showed no differences in the odds of (hospital-treated) self-harm reoccurrence between Culturally and Linguistically Diverse and non- Culturally and Linguistically Diverse self-harm inpatients. However, count components of models show that among those with repeat self-harm, Culturally and Linguistically Diverse people (e.g. born in Southern and Central Asia) made fewer additional hospital revisits than non-Culturally and Linguistically Diverse people. Clinical mental health service contacts following self-harm were made in 63.6% of patients, with Culturally and Linguistically Diverse people (Asian backgrounds 43.7%) less likely to make contact than the non-Culturally and Linguistically Diverse group (65.1%). CONCLUSIONS: Culturally and Linguistically Diverse and non-Culturally and Linguistically Diverse people did not differ in the likelihood of hospital-treated repeat self-harm, but among those with self-harm repetition Culturally and Linguistically Diverse people had fewer recurrences than non-Culturally and Linguistically Diverse people and utilised mental health services less following self-harm admissions.

RESUMO

Introduction: Social competence plays a fundamental role in children's development, and in their functioning at school and in life. Social skills, as learned behaviors that allow children to positively interact with others, are important for success in both academic and peer-group settings. Children's participation in collective music and other arts education has been associated with the development of social skills. However, different measures and diverse programs adopted in various studies make it difficult to contrast study findings. Additionally, research with children from low-income families remains scarce. The aim of this study was to examine the role of music and drama education programs in primary schools on the development of social skills of Portuguese children from disadvantaged communities. Both programs were carefully designed with performing, creating, and listening activities, and were delivered by specialist and experienced teachers/performers, who used active and participatory teaching strategies. Methods: In our longitudinal design with pre- and post-evaluations, we used the Social Skills Rating System or SSRS-Teacher Form, adapted for the Portuguese population. Classroom teachers rated their students' social skills on a 3-point scale in three domains: Social skills (Cooperation, Assertion, Self-control), Behavioral problems (Externalizing problems, Internalizing problems, Hyperactivity) and, on a 5-point scale, Academic competence. Results and Discussion: Our findings suggest that participation in music and drama programs during one school year improved children's assertion and self-control, and cooperation in the drama group. Participation in the music and drama programs also appeared to serve as a protective factor by reducing externalizing, internalizing and behavioral problems. These findings are discussed in light of previous studies along with limitations and directions for future research.

RESUMO

The growing literature on access, participation, and success of refugees entering higher education has illustrated the myriad challenges that this cohort faces. Much of this research has rightly focused on the student perspective, exploring the barriers and challenges that impede entry, engagement, and achievement. Relatedly, there is growing attention to the need for trauma-informed support, particularly following the impacts of COVID on learning. This article takes these challenges as a departure point to adjust the gaze on universities and ask what needs to be considered and implemented in order to develop better student supports. We use Tronto's (2013) notion of ethics of care-examining issues of attentiveness (caring about), responsibility (caring for), competence (caregiving), responsiveness (care receiving), and trust (caring with)-to carefully probe how universities can develop trauma-informed supports that are more caring and nuanced, not only for students from refugee backgrounds but for all students.

RESUMO

Geochemical background and baseline values are important parameters for understanding the geochemical characteristics of soil elements, but the research degree of these two parameters is lacking in Hebei Province. Therefore, data from the multi-purpose regional geochemical survey and land quality geochemical assessment in Hebei Province from 2004 to 2018 were collected, covering approximately 71% of the land area of the whole province. Based on the data of surface soil and deep soil, scientific and robust methods including median value and median absolute deviation were used to calculate the geochemical background values, geochemical baseline values, as well as variation ranges of 54 indexes (Ag, Al2O3, As, Au, B, Ba, Be, Bi, Br, CaO, Cd, Ce, Cl, Co, Cr, Cu, F, Fe2O3, Ga, Ge, Hg, I, K2O, La, Li, MgO, Mn, Mo, N, Na2O, Nb, Ni, P, Pb, pH, Rb, S, Sb, Sc, Se, SiO2, Sn, Sr, Th, Ti, Tl, U, V, W, Y, Zn, Zr, total carbon (TC), and organic carbon (Corg)) in Hebei Province and 11 prefecture-level cities. The change rate in geochemical background for each index was also calculated. The results showed that the geochemical background and baseline values of most soil chemical elements in Hebei Province were lower than those nationwide, but the values of Ba, Br, Cl, MgO, Na2O, P, pH, S, Sr, and TC were higher, with CaO being the highest. Compared with those in north China, there was no significant difference in the geochemical background and baseline values for the 54 indexes, with the ratios of 0.83-1.17 and 0.79-1.19, respectively. Significant changes in the geochemical background for Corg, Hg, N, P, S, and Se were observed in Hebei Province, indicating that these indexes were greatly influenced by human factors. Preliminary analysis suggests that coal burning emissions and agricultural chemical use were two very important inducing factors.

RESUMO

In a natural environment, factors such as weathering and sun exposure will degrade the characteristics of dog feces; disturbances such as decaying wood and dirt are likely to make false detections; the recognition distinctions between different kinds of feces are slight. To address these issues, this paper proposes a fine-grained image classification approach for dog feces using MC-SCMNet under complex backgrounds. First, a multi-scale attention down-sampling module (MADM) is proposed. It carefully retrieves tiny feces feature information. Second, a coordinate location attention mechanism (CLAM) is proposed. It inhibits the entry of disturbance information into the network's feature layer. Then, an SCM-Block containing MADM and CLAM is proposed. We utilized the block to construct a new backbone network to increase the efficiency of fecal feature fusion in dogs. Throughout the network, we decrease the number of parameters using depthwise separable convolution (DSC). In conclusion, MC-SCMNet outperforms all other models in terms of accuracy. On our self-built DFML dataset, it achieves an average identification accuracy of 88.27% and an F1 value of 88.91%. The results of the experiments demonstrate that it is more appropriate for dog fecal identification and maintains stable results even in complex backgrounds, which may be applied to dog gastrointestinal health checks.

RESUMO

Research education and training in Translational Science develops and sustains a workforce to efficiently advance studies designed to improve human health. We evaluated the effectiveness of a Translational Science Training (TST) TL1 Program. Participants had significantly better publications/year, citations/year, h-index, and m-quotient than nonparticipants. Female and male participants, and participants from underrepresented and well-represented backgrounds, performed similarly on all bibliometric assessments. Finally, TST/TL1 Program participants outperformed students from other PhD programs at our institution. This analysis suggests that the TST/TL1 Program has been effective for participants, including those who are female and from underrepresented backgrounds.

RESUMO

Western dementia care policies emphasise that family caregivers from minority ethnic backgrounds must become more engaged in healthcare services. However, research exploring experiences of receiving services such as home-based care, and thus adjustment to the service, among family caregivers from minority ethnic backgrounds who have relatives with dementia is still scarce. Therefore, inspired by Pierre Bourdieu's theoretical concepts of field, habitus and capital, we explored how family caregivers from different minority ethnic backgrounds justified decisions about whether to receive home-based care and their social adjustment to the service. Using empirical data from semi-structured interviews with nine family caregivers from different minority ethnic backgrounds, we demonstrated that different mindsets and available social resources gave rise to various actions. Although some family caregivers were optimistic about receiving home-based care, our findings point to tensions between the ideals of care practices and the organisational structures surrounding home-based care as a service. Among those who had experiences with home-based care, we found that organisational limitations, particularly in terms of efficiency demands and time constraints, influenced their behaviours and thus their social adjustments to the service. For some, these limitations eventually resulted in cancellation of the service. However, not all had the same opportunities to make these decisions, indicating that, although family caregivers from minority ethnic backgrounds receive home-based care, this does not necessarily entail a deficiency-free service. Furthermore, we argue that public discourses on this subject can be challenged by encouraging one to look beyond ethnic and cultural labels towards other factors, such as organisational structures, that might largely influence the use of home-based care among these family caregivers.
