La Tecnología y la Lengua Ancestral Kichwa en la Educación del Sistema de Educación Bilingüe en la Amazonía Ecuatoriana
Authors: Grefa Aguinda. Juan Lenin , Jara García. Geoconda Mercedes
Published: October 2023

El presente estudio explora la intersección de la tecnología y el uso del Kichwa en la educación bilingüe de la Amazonía ecuatoriana. El objetivo principal fue determinar cómo la integración tecnológica afecta la instrucción en Kichwa y la preservación cultural. Utilizando un enfoque metodológico mixto, se revisaron investigaciones recientes publicadas en bases de datos reconocidas y se llevaron a cabo entrevistas con docentes y estudiantes (López & Quishpe, 2018; Ramos, 2019; Gómez & Molina, 2020). Los hallazgos indicaron que, aunque la tecnología ofrece oportunidades para reforzar el aprendizaje en Kichwa, la falta de formación docente y de contenidos adecuados puede comprometer la eficacia de la instrucción bilingüe (Salazar & Guzmán, 2020; Terán & Narváez, 2021). Además, se resaltó la necesidad de equilibrar la enseñanza digital con las prácticas pedagógicas tradicionales (Pérez & Cárdenas, 2019). En conjunto, estos resultados subrayan la importancia de un enfoque holístico que combine innovaciones tecnológicas con respeto y valoración de la herencia cultural Kichwa.

La Enseñanza por Competencia y el Enfoque Semántico Comunicativo de la Enseñanza del Lenguaje
Authors: Ortega Cuello José Luis
Published: October 2023

La formación centrada en competencias se relaciona con cómo los docentes comprenden, internalizan y modulan el proceso educativo con el objetivo de promover habilidades, destrezas y valores definidos, mientras potencian sus propias habilidades como educadores. Este enfoque se basa en principios como la formación holística, la transversalidad, la adaptabilidad y la atención a las demandas sociales, culturales, éticas y económicas, buscando equilibrar el conocimiento teórico con la práctica. Por tanto, se definió como objetivo analizar los fundamentos teóricos que sustentan la enseñanza por competencia y el enfoque semántico comunicativo de la enseñanza del lenguaje. Metodológicamente se fundamentó en un análisis documental cualitativo, el cual hace referencia a un proceso de recuperación, que responde a los requerimientos informativos de los interesados relacionados con conocer primero, lo que otros investigadores han realizado sobre un tema específico y segundo las consideraciones sobre dichas investigaciones. Se concluyó que la enseñanza basada en competencias tiene un fuerte enfoque en la relevancia y pertinencia de lo que se enseña. Reconoce que cada estudiante proviene de un entorno particular y tiene necesidades únicas. Por lo tanto, el proceso educativo debe estructurarse de tal manera que responda a estas realidades, preparando a los estudiantes no sólo para superar exámenes académicos, sino para enfrentar los desafíos que encontrarán en sus comunidades y en el mundo laboral. A diferencia de modelos educativos más tradicionales, donde el estudiante es visto principalmente como receptor pasivo de información, en la enseñanza por competencias, el estudiante se convierte en un actor central en su propio proceso de aprendizaje.

Information Geometry, Jordan Algebras, and a Coadjoint Orbit-Like Construction
Authors:   Universidad Carlos III de Madrid, Spain, Ciaglia Florio M. , Jost Jürgen ,   Max Planck Institute for Mathematics in the Sciences, Germany, Schwachhöfer Lorenz J. ,   TU Dortmund University, Germany
Published: October 2023

Jordan algebras arise naturally in (quantum) information geometry, and we want to understand their role and their structure within that framework. Inspired by Kirillov's discussion of the symplectic structure on coadjoint orbits, we provide a similar construction in the case of real Jordan algebras. Given a real, finite-dimensional, formally real Jordan algebra ${\mathcal J}$, we exploit the generalized distribution determined by the Jordan product on the dual ${\mathcal J}^{\star}$ to induce a pseudo-Riemannian metric tensor on the leaves of the distribution. In particular, these leaves are the orbits of a Lie group, which is the structure group of ${\mathcal J}$, in clear analogy with what happens for coadjoint orbits. However, this time in contrast with the Lie-algebraic case, we prove that not all points in ${\mathcal J}^{*}$ lie on a leaf of the canonical Jordan distribution. When the leaves are contained in the cone of positive linear functionals on ${\mathcal J}$, the pseudo-Riemannian structure becomes Riemannian and, for appropriate choices of ${\mathcal J}$, it coincides with the Fisher-Rao metric on non-normalized probability distributions on a finite sample space, or with the Bures-Helstrom metric for non-normalized, faithful quantum states of a finite-level quantum system, thus showing a direct link between the mathematics of Jordan algebras and both classical and quantum information geometry.
MATHEMATICAL MODEL FOR THE STUDY OF OBESITY IN A POPULATION AND ITS IMPACT ON THE GROWTH OF DIABETES
Authors: Moya Erick Delgado , Pietrus Alain , Bernard Séverine
Published: October 2023

In this paper, we present a deterministic mathematical model for the study of overweight, and obesity in a population and its impact on the growth of the number of diabetics. For the construction of the model, we take into account social factors and the interactions between the elements of society. We find the basic reproduction number and prove the global stability of the disease-free equilibrium point. We present theoretical results and find the sensitivity indices to characterize the impact of parameters associated with overweight, obesity and diagnosed diabetes on the basic reproduction number. To validate the model, we perform computational simulations and study the basic reproduction number and compartments. We present the behavior of the compartments for a scenario and study the impact of the variation of parameters associated with overweight by social pressure and diabetes due to causes other than obesity.

Authors: Kozulinas Nikolajus , Panasenko Grigory , Pileckas Konstantinas , Šumskas Vytenis
Published: October 2023

The dimension reduction for the viscous flows in thin tube structures leads to equations on the graph for the macroscopic pressure with Kirchhoff type junction conditions in the vertices. Non-Newtonian rheology of the flow generates nonlinear equations on the graph. A new numerical method for second order nonlinear differential equations on the graph is introduced and numerically tested.

The presence of aerosols is intimately linked to the global energy budget and the composition of a planet’s atmosphere. Their ability to reflect incoming light prevents energy from being deposited into the atmosphere, and they shape the spectra of exoplanets. We observed five near-infrared secondary eclipses of WASP-80b with the Wide Field Camera 3 (WFC3) aboard the Hubble Space Telescope to provide constraints on the presence and properties of atmospheric aerosols. We detect a broadband eclipse depth of 34 ± 10 ppm for WASP-80b. We detect a higher planetary flux than expected from thermal emission alone at 1.6σ, which hints toward the presence of reflecting aerosols on this planet’s dayside, indicating a geometric albedo of A

g
< 0.33 at 3σ. We paired the WFC3 data with Spitzer data and explored multiple atmospheric models with and without aerosols to interpret this spectrum. Albeit consistent with a clear dayside atmosphere, we found a slight preference for near-solar metallicities and for dayside clouds over hazes. We exclude soot haze formation rates higher than 10−10.7 g cm−2s−1 and tholin formation rates higher than 10−12.0 g cm−2s−1 at 3σ. We applied the same atmospheric models to a previously published WFC3/Spitzer transmission spectrum for this planet and found weak haze formation. A single soot haze formation rate best fits both the dayside and the transmission spectra simultaneously. However, we emphasize that no models provide satisfactory fits in terms of the chi-square of both spectra simultaneously, indicating longitudinal dissimilarity in the atmosphere’s aerosol composition.
The Distribution of High-excitation OCS Emission Around the Cep A-East Protostellar Cluster
Authors: Codella C. , Bachiller R. , Viti S.
Published: October 2023

The Cepheus A East high-mass star-forming region has been mapped at 1.4 mm using the OCS(17–16) and (18–17) lines observed with the IRAM 30 m antenna. Contour maps and high-resolution line profiles reveal the association of OCS with both (i) the hot-core region, and (ii) with the NE, SE, and S outflows driven by the young stellar objects. This confirms that OCS is among the main S-molecules observed in the gas-phase after thermal evaporation due to protostellar heating or shocks due to propagation of protostellar jets. Adopting Local Thermodynamic Equilibrium conditions, optically thin emission, and a temperature of 100 K, the total OCS column density (after correction for beam dilution) of the hot-core component is ∼1016 cm−2. For the outflow component, assuming a temperature range of 20–100 K, and extended emission, the OCS column density is ≤ 5 ×1014 cm−2 for a temperature ≥ 20 K.
Notes on the pattern of head size in the Philippine Spotted Flying Lizard, Draco spilopterus (Weigmann, 1834), within Luzon Biogeographic Region, Philippines
Authors: Tabug Michael A. , Necesito Levy V. , Diesmos Arvin C.
Published: October 2023

Sexual head dimorphism is a condition where head morphology of male and female of the same species differ, which provides an additional way to recognise sex for species identification. Fifty four adult Philippine Spotted Flying Lizards, Draco spilopterus, were examined from four populations in the Luzon Island, Philippines to assess whether head morphometry can drive sexual dimorphism. We identified the sex and measured five morphometric measurements of the head (jaw length, jaw width, head height, head length, head width) and snout-vent length. A univariate analysis of the five morphometric measurements showed clear sexual dimorphism. Considering all individuals, female heads are significantly larger than those of males (all p-values < 0.05). We also revealed major differences in head size amongst the four populations due to their geographical location and habitat differences.
Nuclear data uncertainty on generation IV fast reactors criticality calculations analysis comparison
Authors: Chereshkov Dimitar G. , Ternovykh Mikhail Yu. , Tikhomirov Georgiy V. , Ryzhkov Alexander A.
Published: October 2023

The new calculation code capabilities are applied in the current work as well as important fast reactor criticality parameters uncertainty assessment articles’ results based on different nuclear data libraries and covariance matrices. A comparative analysis of uncertainty estimations related to neutron reactions is presented for lead-cooled reactor models and sodium-cooled reactor models. For the models of advanced BN and BR fast reactors with three fuel types (UO2, MOX, MNUP), the multiplication factor uncertainty calculations are performed using 252-group covariance matrices based on ENDF/B-VII.1 library via the SCALE 6.2.4 code system. The main nuclear data uncertainty contributors in the multiplication factor are determined. Recommendations are formulated for improving the cross sections accuracy for several nuclides in order to provide more reliable results of fast reactor criticality calculations. Lead-cooled reactors have no operational history compared to light-water and sodium-cooled reactors. The experimental data insufficiency calls in the question about reliability of the simulation results and requires a comprehensive initial data uncertainty analysis for the neutron transport simulation. The obtained results support the idea that lead- and sodium-cooled reactors have close nuclear data sensitivity using one and the same computation tools, nuclear data libraries and fuel compositions. This makes it possible to use the accumulated data of benchmarks for sodium-cooled reactors in the safety determination of lead-cooled reactors.

Published: October 2023

Insects have highly variable reproductive systems, reflecting a diversity of reproductive strategies and adaptations. Such variation has been widely used to classify and estimate phylogenetic relationships. Here, the morphology and ultrastructure of the internal reproductive systems of two leafhopper species are described and illustrated, using both light and transmission electron microscopy, and representing two tribes of Deltocephalinae: in Chiasmini, Nephotettix cincticeps (Uhler, 1896), and in Deltocephalini, Deltocephalus vulgaris (Dash & Viraktamath, 1998). Tables comparing the morphology of male and female internal reproductive structures of these studied species are provided and indicate that the main differences are in the relative shapes, sizes, and colors of these structures. The overall structure and organization, including details of the ultrastructure, of these two leafhopper species’ male and female internal reproductive systems are very similar to those of previously studied leafhoppers. The main differences observed among species include the number of testicular follicles, the relative position of seminal vesicles and the degree of development of the accessory glands in the male, the number of ovaries, and the shape and color of the vagina and spermatheca in the female.
'Everything Changes in Nature': Kropotkin's Process Philosophy
Authors: Sandberg Ole Martin
Published: October 2023

A frequent misunderstanding about Peter Kropotkin, and anarchism more generally, is that by emphasising mutual aid as a factor of evolution and history, he advocates a view of human nature as essentially benign. This essay aims to disprove that claim by showing that Kropotkin explicitly
rejects any notion of a fixed human essence and insists that we are composed of a multitude of autonomous but interacting faculties with no authentic or essential centre. This view of the human psyche reflects his view of the world in general: for Kropotkin, philosophy and science were not
about finding universal mechanisms and eternal substances. Instead, he advances a view of the world that can only be described as process-thinking: a philosophical tendency that prioritises difference over identity and change over stability. Kropotkin's process ontology also informs his view
of politics, which rejects the idea of a harmonious social end state free of conflict and embraces diversity as a factor that promotes progress and movement. Kropotkin's process philosophy has relevance to debates in such diverse fields as philosophy and metaphysics, political and social theory,
and biology and ecology.
Kropotkin and Revolution
Authors: Baker Zoe
Published: October 2023

Anarchists, and Kropotkin in particular, are often depicted as optimists who lack a realistic view of how to achieve fundamental social change. This article counters this narrative by reconstructing Kropotkin's views on revolution and the arguments he used to justify it. In particular,
I demonstrate that Kropotkin developed complex theories about how revolutions arise, what form a revolution must take in order to succeed, and how anarchists should act to achieve their goals. Kropotkin did not ignore or downplay the difficulties that any revolution would encounter.Instead,
he considered the potential obstacles and developed coherent arguments for why the methods of anarchism were best suited to overcome them.
The characteristic polynomials of semigeneric threshold arrangements
Authors: Gao Ruimei , Wang Yuyu
Published: October 2023

The semigeneric threshold arrangement is the hyperplane arrangement defined by $ x_i+x_j = a_{i} $, where $ 1 \leq i < j \leq n $ and $ a_i\text{'s} $ are generic elements. In this paper, we obtain a necessary and sufficient condition for subarrangements of the semigeneric threshold arrangement to be central from the perspective of simple graphs. Combining it with Whitney's theorem, we provide a formula for the characteristic polynomials of the semigeneric threshold arrangement and its subarrangements.
Rich and complex dynamics of a time-switched differential equation model for wild mosquito population suppression with Ricker-type density-dependent survival probability
Authors: Zhu Zhongcai , He Xue
Published: October 2023

Dengue presents over 390 million cases worldwide yearly. Releasing Wolbachia-infected male mosquitoes to suppress wild mosquitoes via cytoplasmic incompatibility has proven to be a promising method for combating the disease. As cytoplasmic incompatibility causes early developmental arrest of the embryo during the larval stage, we introduce the Ricker-type survival probability to assess the resulting effects. For periodic and impulsive release strategies, our model switches between two ordinary differential equations. Owing to a Poincaré map and rigorous dynamical analyses, we give thresholds $ T^*, c^* $ and $ c^{**} (>c^*) $ for the release period $ T $ and the release amount $ c $. Then, we assume $ c > c^* $ and prove that our model admits a globally asymptotically stable periodic solution, provided $ T > T^* $, and it admits at most two periodic solutions when $ T < T^* $. Moreover, for the latter case, we assert that the origin is globally asymptotically stable if $ c\ge c^{**} $, and there exist two positive numbers such that whenever there is a periodic solution, it must initiate in an interval composed of the aforementioned two numbers, once $ c^* < c < c^{**} $. We also offer numerical examples to support the results. Finally, a brief discussion is given to evoke deeper insights into the Ricker-type model and to present our next research directions.
A aceleração recente da produção de soja na Amazônia: uma história do desmonte ambiental “em prática” no estado de Roraima
Authors: Eloy Ludivine , Senra Estevão B. , da Silva Andréa Leme , Campos Ciro
Published: October 2023

Como evoluíram as políticas ambientais e
fundiárias no norte da Amazônia brasileira para acomodar a expansão da
soja? Neste artigo, focamos no caso de Roraima, onde a superfície de
soja aumentou 257 % entre 2018 e 2021. Analisamos em que medida esta
aceleração pode ser atribuída à ascensão de J. Bolsonaro ao poder.
Utilizamos um método interdisciplinar para identificar os espaços,
atores e mecanismos econômicos e legais envolvidos neste processo. Os
dados são oriundos de pesquisa de campo (observações e entrevistas),
documentos oficiais, interpretação visual de imagens de satélite e
geoprocessamento.O cultivo da soja iniciou em 2000. Desde 2009,
um sistema estadual de licenciamento ambiental simplificado facilita a
instalação de empresas. A integração soja/pecuária promove a
concentração e a valorização fundiária nas zonas florestais, porém
limitadas pela exigência de 80 % de Reserva Legal e pela falta de
regularização fundiária, sobretudo na faixa de fronteira. Desde
2018, o governo Federal, em parceria com o governo do Estado,
simplificou a regularização fundiária e destravou a redução da Reserva
Legal nas zonas florestais em 2022 (de 80 % para 50 %). Essas reformas
representam um incremento de 1,6 milhão de hectares de floresta
passível de desmatamento legal no Estado. É o início de uma nova fase
de expansão agroextrativa no norte da Amazônia brasileira, no coração
da floresta, e não apenas nas suas bordas, como no passado.

d’analyser la pluralité des modes d’action entrepreneuriaux pour
accélérer l’exploitation de minerais, que ce soit par le lobbyisme, la
répression, la menace ou l’utilisation opportuniste d’un gouvernement
favorable à l’extraction de minerais et conciliant envers les intérêts

DNA Release from Polyaziridine Polyplexes Aided by Biomacromolecules: Effect of pH
Authors: Bibi Iram , Shah Syed Waqar Hussain
Published: October 2023

The pH dependence of heparin and dextran sulfate aided release of DNA from its polyplexes with polyaziridine (PA) has been investigated using Quartz crystal microbalance with dissipation monitoring (QCM-D). The acoustic behavior of ternary systems indicated that the DNA decondensation was favored at physiological pH. When pH < 7.4, PA was significantly positively charged and ternary complexation occurred. When pH exceeded 7.4, very small proportion of DNA was released upon heparin addition due to marked reduction in cationic nature of PA. An increase in thickness at the interface due to adsorbed material at pH 9.0 showed the retention of heparin on the surface despite of negligible release of DNA. In terms of PA binding, heparin proved to be a better competitor than dextran sulfate.
Numerical Integration of locally Peaked Bivariate Functions
Authors: Zaidi Abdelhamid Taieb
Published: October 2023

The aim of this paper is to compare the relative accuracies between deterministic and stochastic methods for solving bounded integrals numerically to observe which methods tend to function well and converge to a small amount of error based on computational resources. For the deterministic method, the Gauss-Legendre quadrature method has been selected and for the stochastic method, the Monte Carlo integration has been selected. For each case, the number of variables will be adjusted to observe the effect on error. For the Gauss-Legendre quadrature method the permutations increased with the inaccuracy of 9% when the number of nodes increased to 3 but was reduced by 90% and later on the error depicted a drop as the number of nodes raised further. For the stochastic method, that was chosen from large sample size, the inaccuracy was found to be inversely proportional to the sample size. This concluded that the monte-carlo approach was not affected by the impact of dimensionality moreover, deterministic method also seemed to overcome the dimensionality constraint.

Portfolio analysis is widely used by financial investors to find portfolios producing efficient results under various economic conditions. Markowitz started the portfolio optimization approach through mean-variance, whose objective is to minimize risk and maximize the return. This study is called Markowitz Mean-Variance Theory (MVP). An optimal portfolio has a good return and low risk, in addition to being well diversified. In this paper, we proposed a methodology for obtaining an optimal portfolio with the highest expected return and the lowest risk. This methodology uses Mixture Design of Experiments (MDE) as a strategy for building non-linear models of risk and return in portfolio optimization; computational replicas in MDE to capture dynamical evolution of series; Shannon entropy index to handle better portfolio diversification; and desirability function to optimize multiple variables, leading to the maximum expected return and lowest risk. To illustrate this proposal, some time series were simulated by ARMA-GARCH models. The result is compared to the efficient frontier generated by the traditional theory of Markowitz Mean-Variance (MVP). The results show that this methodology facilitates decision making, since the portfolio is obtained in the non-dominated region, in a unique combination. The advantage of using the proposed method is that the replicas improve the model precision.
Investigation of the use of hemp fibers in recycling spinning

In recycle yarn spinning, the original fibers are added to the blend as a carrier because of the recycled fibers obtained by opening from fabric scraps are very short and coarse. In the textile recycling industry, mostly petroleum-based synthetic fibers are used as carrier fibers. In an environmentally important activity such as recycling spinning, it is necessary to reduce the use of synthetics used as carrier fibers. When considered from this point of view, hemp fibers come to the fore with their important performance and environmental features. Based on this fact, in this study, in addition to the standard production conditions in the recycling yarn production facility, hemp fibers in different proportions were added to the blends to reduce the ratio of polyester as carrier fiber and the effects of this situation on yarn quality were examined. According to the results, it was observed that adding hemp fiber to the recycle yarn blend increased yarn tenacity, yarn unevenness and yarn hairiness while decreased yarn elongation properties.

Dehydrated cranberries (Vaccinium macrocarpon) are dried fruits known for their high antioxidant potential. Changes in their mechanical and rheological properties occur when cranberries are exposed to certain conditions, such as drying or immersion in a liquid medium (rehydration). To evaluate the rheological behavior of solid suspensions made from dehydrated cranberries, the effects of different temperatures and concentrations of dissolved solids were evaluated using a factorial experimental design (22) with three replications at the center point. Five models were used to investigate the suspensions' flow behavior: Ostwald de Waelle, Newton, Herschel-Bulkley, Casson, and Bingham. The rheometry of the suspensions showed that the fluids presented non-Newtonian behavior, with a satisfactory fit for the Casson model (R² > 0.94) in all evaluated temperature and concentration ranges. Furthermore, the effects of temperature and solid concentration of cranberry suspensions on the rheological parameters of the fitted model, Casson's initial shear stress (K0c), and Casson's plastic viscosity (Kc) were evaluated. From the response and the contour surfaces, it was found that increasing the concentration of the suspension above 20% resulted in higher initial shear stress, which was influenced by temperature, whose increase resulted in a significant reduction in the shear stress at a concentration of 30%. The plastic viscosity (Kc) was highly influenced by the solid’s concentration, and higher temperatures caused a decrease in the value of this parameter. So, the highest value of plastic viscosity was found for concentrations above 20% and at lower temperatures. Therefore, considering the results and for practical purposes, it can be concluded that the flow of the suspensions is facilitated if rehydration is conducted at high temperatures.

Clinical Practice Patterns of Interprofessional Collaboration: Considerations for Athletic Training Education
Authors: Hankemeier Dorice A. , Manspeaker Sarah A. , Feld Sharon D. , Kirby Jessica L.
Published: October 2023

Context

As required elements of accreditation, interprofessional education (IPE), and interprofessional collaborative practice (IPCP) are key considerations for athletic training educators, students, and practicing professionals.

Objective

Despite the emphasis on IPE and IPCP, little information exists regarding which health care professionals athletic trainers should collaborate with outside of physicians. In addition, no study has established which professionals athletic training students should be educated alongside in preparation for future interprofessional collaboration.

Design

Cross-sectional survey.

Setting

Clinical practice settings.

Patients or Other Participants

Stratified sample of 105 athletic trainers across various employment settings.

Data Collection and Analysis

Participants selected the top 5 health care professionals with whom they currently interact, desire to collaborate, and believe students should be learning to interact with during clinical practice. Participants indicated how much time they spent in collaborative practice and the frequency and method of their interactions. We analyzed data using descriptive statistics including means, standard deviations, and frequency counts.

Results

In addition to physicians, participants identified physical therapists, physician assistants, nurses, and nurse practitioners as the primary professionals with whom they interacted in the past 12 months. Participants identified a desire to collaborate with sport and exercise psychologists, physical therapists, nutritionists, physician assistants, and certified or licensed professional counselors. In addition, participants indicated that athletic training students should learn with physical therapists, paramedics or emergency medical technicians (EMTs), physician assistants, nutritionists, and sport and exercise psychologists in preparation for future clinical practice. Regarding time, the majority (64.7%) of participants interact with other health care professionals multiple times a day or week.

Conclusions

These results are indicative of the need to prepare athletic training students to engage in collaboration with professionals beyond the naturally occurring partnerships with physicians. Educators could use these findings in the development or modification of IPE experiences, and the results may be considered in the development of continuing education opportunities to enhance practicing athletic trainers’ collaborations.

Background: Establishing a culture of patient safety in the healthcare system is essential to making improvements in the quality of care  and patient outcomes. Aim: To assess the perceptions of patient safety culture among healthcare professionals (HCPs) in selected public hospitals in Kaduna state, Nigeria.

Methods: A cross-sectional survey using the Hospital Survey  on Patient Safety Culture (HSOPSC) was  conducted. Data was collected from healthcare professionals (medical doctors, nurses, and pharmacists) from four (4) public hospitals  that met the inclusion criteria. Data were analysed using SPSS version 23 and summarized as percentages, means, and standard  deviations. The chi-square test was used to examine statistical associations between HCP characteristics and outcome variables.

Results:  Three hundred and fifty-eight (358)  questionnaires were completed and returned (response rate of 84.8%). The overall average of the  percent positive response of patient safety culture across the health  facilities was 55.6%. 'Teamwork within units' was the dimension with  the greatest strength (81.3%). The dimensions with the most potential for improvement with average positive responses below 50%  were 'Staffing' (34.4%), 'Frequency of events reported' (36.8%), and 'Non-punitive response to errors' (40.5%). A higher percentage of  pharmacists (n=25, 48.1%) compared to other HCPs had reported at least an error in the preceding 12 months, and this was statistically  significant (p < .001).

Conclusion: Overall perception of patient safety culture was  slightly above average (55.6%) with four out of twelve dimensions measured having an average score below 50%. Further assessment of patient safety culture, particularly in the areas with poor responses is  required to improve the quality of care and promote healthcare improvement.

Introduction: Breast cancer (BrCa) survivors have increased globally with the continued improvement in cancer management. Despite  this, there are significant issues experienced by these women during BrCa treatment. It is therefore important to explore the unique  experiences of women who are long-term BrCa survivors.

Objective: This study aimed to explore the lived experiences of 22 women who  are long-term BrCa survivors in Lagos State, Nigeria.

Methodology: A phenomenological approach was used to carry out one-on-one  unstructured interviews with the participants, who were selected purposively using a snowball sampling technique. The interviews were  analysed using Nvivo 14 to identify themes and subthemes.

Result: The participants were 5 years or more, post-treatment for BrCa, with  an average age of 43 years at the time of diagnosis. Four themes emerged: (i) In the very beginning, (ii) Going through difficult times, (iii)  Becoming a survivor, and (iv) Living as a survivor. Sixteen subthemes were also identified. The participants had a self-identification  pattern as survivors, and an interpretation of their experiences which were influenced by a cascade of factors including spirituality, family  support, financial burden, counselling and  emotional support which differs from one participant to the other.

Conclusion: The  study highlights the unique experiences of long-term BrCa survivors and the challenges they face on their journey to survivorship. Early  diagnosis, inner strength, family support, faith, and quality treatment were identified as important factors in fighting cancer and reaching  survivorship. The findings have implications for nurses and other healthcare providers, who should acknowledge the distinct   experiences of these women to provide appropriate support and care.
