In this paper, we consider a class of singular variable-order fractional Kirchhoff problem of the form: where is a bounded domain, is the variable-order fractional Laplacian operator, [u]s(·) is the Gagliardo seminorm and is a continuous and symmetric function. We assume that λ is a non-negative parameter, with and. We combine some variational techniques with a truncation argument in order to show the existence and the multiplicity of positive solutions to the above problem. [ABSTRACT FROM AUTHOR]

Interviews were conducted until data saturation was reached. A conventional content analysis approach was used.Results: Thirty-four participants were interviewed. Subjects perceived ageing as a factor leading to changes in their living environment. However, they did not spontaneously evoke their functional/structural impairments nor their activity limitations as if the change of living environment could reduce the perceived loss of autonomy by maintaining an acceptable participation. Participants mostly experienced change as both inevitable and as a relief as it took them out of isolation and domestic hardship. This reaction was somewhat facilitated by spiritual beliefs as the changes were interpreted as the will of spiritual forces. Family and social relationships appeared to be more important determinants of participants’ perception of changes in living environment than was health status. We found differences between the three groups regarding familial relationship, fear of death, acceptance of change, and unmet needs. Unmet needs were particularly expressed by those living in foster care. The concept of “feeling at home”, which emerged as essential for all participants, was lacking in foster care families.Conclusion: Perceived autonomy, including not only functional/structural impairments, but also, social interactions, should be carefully considered when developing support services for older individuals.Keywords: older people, nursing home, autonomy, quality of life, foster care family

In this paper, we consider a class of fractional Laplacian problems of the form: { (− Δ) p (x ,.) s u + μ | u | q (x) − 2 u = λ g (x) u − γ (x) + f (x , u) in Ω , u = 0 , on ∂ Ω , where Ω ⊂ R N , (N ≥ 2) , is a bounded domain and (− Δ) p (x ,.) s is the fractional p (x ,.) -Laplacian operator. We assume that λ and μ are positive parameters and γ : Ω ¯ → (0 , 1) is a continuous function. By opting for the Nehari manifold method combined with the theory of generalized Lebesgue Sobolev spaces, we will prove the existence of solutions to the above problem. [ABSTRACT FROM AUTHOR]

In this paper, we consider a class of p (x) -Laplacian problems of the form: (− Δ) p (x) u + a (x) | u | p (x) − 2 u = f (x , u) in Ω , | ∇ u | p (x) − 2 ∂ u ∂ v + b (x) | u | q (x) − 2 u = g (x , u) on ∂ Ω , where Ω ⊂ R N , N ≥ 2 is a bounded domain with Lipschitz boundary ∂ Ω , (∂ / ∂ v) is outer unit normal derivative. The functions a, b, p, q, g and f are assumed to satisfy suitable assymptions. The existence and the multiplicity of solutions is obtained by using variational methods, and mountain pass lemma combined with Ekeland variational principle. [ABSTRACT FROM AUTHOR]

In this paper, we consider a class of fractional Laplacian problems of the form: (− Δ) p 1 (x ,.) s u + (− Δ) p 2 (x ,.) s u + | u | q (x) − 2 u = g (x) u − γ (x) + λ f (x , u) in Ω , u = 0 , on ∂ Ω , where Ω ⊂ R N , (N ≥ 2) , is a bounded domain and (− Δ) p i (x ,.) s is the fractional p i (x ,.) -Laplacian. We assume that λ is a nonnegative parameter and γ : Ω ¯ → (0 , 1) is a continuous function. By using variational methods and monotonicity arguments combined with the theory of the generalized Lebesgue Sobolev spaces, we prove the existence of solutions to problem (P λ).

Today, the generalization of data processing in all the industry branches leads to the construction of large databases, The exploitation of these data in various fields calls upon analysis and knowledge extraction techniques. Clustering is one of the most used techniques. Several clustering platforms were proposed in order to allow an effective and fast data grouping, These platforms integrate various approaches. However, they present several limits. In this paper, we propose a new platform, called EvaICluster, which a) integrates several clustering approaches b) allows the data processing which coming from various data sources c) interprets graphically the clustering results and d) evaluates the clustering quality and e) calculates the performances of implemented approaches.

Aim: In the present study, we evaluated the triage process particularly for older patients after calls to Emergency Medical Call Centers (ECC), according to the geriatric assessment tool., Methods: In this observational population-based cross-sectional study in the Rhône (France), we analyzed the audiotapes of all calls received by ECC concerning patients aged ≥75 years, during seven randomly selected days, over a period of 1 year. We analyzed whether information about seven key items, predefined by a panel of experts as essential for quality telephone triage of seniors, was actually collected., Results: Among 4168 calls, 712 (17.1%) concerned patients >75 years (mean ± SD, age 84.6 ± 5.6 years). The mean duration of calls was 3 min 28 s. Information about living arrangements (alone or not), dependency, multiple pathologies, polymedication, ability to walk independently or with help, and hospitalization in the previous 3 months was not collected in 20%, 42%, 40%, 45%, 58% and 61% of calls, respectively. All seven geriatric items were collected for only 54 (7.8%) calls, and only three criteria collected for 277 (40%) calls. Nurse-managed calls were significantly associated with the collection of less geriatric items compared with physician-managed calls., Conclusion: Key information is particularly important to guide the orientation, and further management of older patients may be lacking during the telephone triage of patients in ECCs. This may represent an important level of improvement of the triage process, to address the needs of older patients better and avoid inappropriate emergency department visits.

Background: The rapid increase in the number of older people with loss of autonomy and requiring human support, medical services, and adapted accommodation is a challenge in many countries. Beside institutions for older people, foster care families may offer an interesting innovative and affordable alternative that should to be evaluated. As the place of living has a major impact on the quality of life, our objective was to compare the perceptions and experience of older adults depending on the type of accommodation in which they live in. Methods: This study was based on a mixed method approach, with a quantitative assessment and a qualitative study with semi-structured interviews conducted with older people living in two different types of institutions: medico-social institution and foster care families. We explored the perceptions and the quality of life of the participants. Results: Institutionalization, chosen or not, can represent a trauma for older people as it disrupts their personal habits. Participants described medico-social institutions as an institutional framework supported by a strict professional team and rules, as impersonal structures (i.e., somewhat neutral), and as offering a very present, prepared, and respected reception protocol on the first day of arrival, which remained marked in memories. On the other hand, foster care families were considered as more spontaneous and family-oriented structures relying on internal and negotiable rules, offering personalized and close support in the face of loss of autonomy, but in which the reception protocol on the first day of arrival was almost absent. Conclusions: Foster care families and medico-social institutions presented different advantages and disadvantages from the point of view of the participants. This can help health policy makers to rethink the way seniors are housed by taking into consideration their perception and quality of life., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Chammem, Domi and Schott.)
