“Roses that Grew from Concrete”: Racialized Biopolitics in Angie Thomas’ Fictions
No full textAngie Thomas (1988-) is a contemporary African American woman writer noted for her activist identity and her examination of Black experience (particularly young adults experience) within the Black community. She has won the Boston Globe-Horn Book Award, the Waterstones Children’s Book Prize, and the ALA’s William C. Morris Debut Award. Thomas is the author of 3 novels, including The Hate U Give (2017), On the Come Up (2019) and Concrete Rose (2021). The three novels all involve the literary descriptions of physical discipline, power repression, and institutional manipulation experienced by African American young adults in the process of growing up, and profoundly touch upon social problems such as police brutality, systematic poverty and discourse penetration in the United States. The writing about black experience reveals that racial violence is still rampant in American society.Based on Foucault, Agamben, and Mbembe’s theories of biopolitics, this paper takes Angie Thomas’s three fictions as research object, explores how biopower continues to govern and manipulate blacks in the economic, political and ideological levels via more varied means, which, to different degrees, leads to the mechanism of inclusive exclusion that reduces blacks into the killable homo sacer. The paper further points out that the three novels demonstrate that when the black population is included in the macro governance of biopower, blacks could be utilized as the target of a society of enmity, suppressed or eliminated by the authorities as a threat to the security mechanism, and their bodies can also be commoditized as a resource for exploitation in America’s racial economy. Meanwhile, the sovereign also uses ideological discourse to erase the humanity of African Americans in the media, education and other fields, making it more reasonable to oppress and manipulate blacks
Assessment and international students - black African social work students
No full textThis evaluative study focuses on the perceptions of black African (international and home) students on an undergraduate social work programme. In particular this article will consider the more traditional assessment of examinations, where the students perceived that their grades were higher due to a familiarity with the assessment strategy. In contrast, they referred to the bewildering 'other world‘ of less familiar assessment processes which demanded a deeper level of critical thinking skills for example in assignments. This evaluation aims to consider whether the African students‘ perceptions that their academic grades fared better dependent on the assessment process is in fact a reality compared to other less familiar ones
A Multisensory Approach to Enhance Autistic Learners' Reading Skills
No full textEsta investigación-acción pretendía averiguar la utilidad de las lecciones basadas en la multisensorialidad para reforzar las destrezas lectoras de los autistas. Cuatro estudiantes autistas de un grupo de veintiséis alumnos de un colegio privado participaron en la puesta en práctica y evaluación de varias lecciones. Se llevó a cabo un ciclo de investigación-acción de cinco semanas en el que se enseñó a los alumnos vocabulario, se identificaron las ideas principales y las palabras clave de un texto para ayudarles a leer mejor. Los resultados mostraron que los estudiantes autistas tienden a tener un mejor rendimiento cuando los profesores se centran en actividades multisensoriales para ayudarles en su proceso de aprendizaje del inglés. Utilizar varios sentidos durante el aprendizaje ayuda a los alumnos autistas a comprender y recordar la información con mayor eficacia. Este enfoque es especialmente beneficioso en los ejercicios de lectura, ya que los hace más fáciles y accesibles.This action research aimed to find out the usefulness of multisensory-based lessons to strengthen autistic reading skills. Four Autistic students from a group of twenty-six students from a private school participated in the implementation, and assessment of several lessons. An action research cycle of five weeks was implemented while students were taught vocabulary and identified the main ideas, and keywords of a text to help them do better while reading. Outcomes showed that autistic students tend to have better performance when teachers target multisensory activities to assist their English language learning process. Engaging multiple senses during learning helps students with autism understand and recall information more effectively. This approach is particularly beneficial in reading exercises, making them easier and more accessible.AbstractIntroductionTheoretical frameworkMultisensory methodologyAutismReadingLiterature reviewMethodologyResearch designContext and ParticipantsResearcher’s roleData collectionEthical considerationsData analysisUnit Intervention stageFindingsDiscussion of findingsConclusionsReferencesAppendix 1.

The quality and adequacy of care received at home in the last 3 months of life by people who died following a stroke: a retrospective survey of surviving family and friends using the Views of Informal Carers Evaluation of Services questionnaire
No full textStroke is the third leading cause of death in the UK. Despite this, little is known about the care needs of people who die from or following a stroke. In early 2003, a total of 183 questionnaires were returned from a survey of 493 people who had registered a stroke-related death in four Primary Care Trusts, giving a response rate of 37%. This paper reports on 53 deceased from the survey who had lived at home during their last 3 months and who had been ill for more than 1 month. The data were analysed to explore the role of informal carers and the provision of community-based care in the last 3 months of life. Family and friends helped 82% of deceased with household tasks, 68% with personal care, 66% with taking medication and 54% with night-time care. By contrast, health and social services helped 30% with household tasks, 54% with personal care, 20% with taking medication and 6% with night-time care. Two-fifths (43%) of informants had to give up work or make major life changes to care for the deceased, and 26% of informants found looking after them ‘rewarding’. Half (51%) reported that help and support from health services were excellent or good compared to 38% for social services. Results from the Regional Study of Care for the Dying indicated that people who died from a stroke in 1990 and their informal carers would have benefited from increased levels of community-based care and enhanced communication with care professionals. Our data suggest that informal carers continue to provide the majority of care for those who die from stroke, despite government initiatives to improve care for stroke patients and frail elderly people. Further research is required to explore best practice and service provision in caring for this group.<br/

No full textAntecedentes: La reconstrucción de defectos críticos en el complejo craneofacial presenta desafíos importantes debido a la ausencia de métodos efectivos para optimizar la regeneración ósea. Actualmente, existe una brecha en el uso de células madre dentales humanas (hDPSCs) combinadas con andamios biocompatibles y señales bioquímicas. Este estudio aborda estas limitaciones mediante un análisis in silico, ofreciendo soluciones innovadoras en odontología regenerativa. Objetivo: Determinar el diseño óptimo de un implante mandibular personalizado para la reconstrucción de un defecto óseo de tamaño crítico mediante análisis in silico. Metodología: Este estudio se centró en la identificación de proteínas osteogénicas mediante análisis in silico utilizando la plataforma STRING, explorando redes funcionales y asociaciones entre factores de crecimiento osteogénicos y el secretoma de las células madre dentales (hDPSCs). Se aplicaron criterios de inclusión y exclusión para seleccionar las proteínas más relevantes, identificando aquellas sobreexpresadas o subexpresadas en hDPSCs. Con base en los resultados, se diseñó un implante mandibular personalizado utilizando los softwares Nemofab y Geomagic, partiendo de imágenes obtenidas de una tomografía computarizada (TC) del paciente. Estas imágenes fueron importadas al software CAD para modelar el implante con precisión, seguido por manufactura asistida por computadora (CAM) para su producción. Finalmente, se empleó realidad aumentada para simular la colocación del implante en un entorno virtual que replicó la anatomía específica del paciente, permitiendo una evaluación prequirúrgica detallada y ajustes precisos. Este enfoque busca optimizar la regeneración ósea y proporcionar soluciones innovadoras en odontología regenerativa. Resultados: El análisis in silico demostró que las hDPSCs tienen un potencial osteogénico superior, consolidándose como una opción prometedora para la regeneración ósea en defectos críticos. Además, la incorporación de proteínas morfogenéticas óseas (BMP-2) aceleró significativamente los procesos de osificación, promoviendo la formación de nuevo tejido. La integración de estas herramientas avanzadas mejoró la visualización y planificación quirúrgica, incrementando la precisión y seguridad del procedimiento. La exitosa aplicación en un caso clínico real valida la aplicabilidad práctica del proyecto, con impacto directo en la salud del paciente. Conclusiones: Este análisis in sílico confirma que las hDPSCs representan una alternativa efectiva para la regeneración ósea en defectos críticos.

Currently, a gap exists in the use of human dental stem cells (hDPSCs) combined with biocompatible scaffolds and biochemical signals. This study addresses these limitations through in silico analysis, offering innovative solutions in regenerative dentistry. Aim: To determine the optimal design of a customized mandibular implant for the reconstruction of a critical-size bone defect by in silico analysis. Methods: This study focused on the identification of osteogenic proteins by in silico analysis using the STRING platform, exploring functional networks and associations between osteogenic growth factors and the secretome of dental stem cells (hDPSCs). Inclusion and exclusion criteria were applied to select the most relevant proteins, identifying those over- or underexpressed in hDPSCs. Based on the results, a customized mandibular implant was designed using Nemofab and Geomagic software, starting from images obtained from a computed tomography (CT) scan of the patient. These images were imported into CAD software to accurately model the implant, followed by computer-aided manufacturing (CAM) for its production. Finally, augmented reality was used to simulate implant placement in a virtual environment that replicated the patient's specific anatomy, allowing for detailed pre-surgical evaluation and fine- tuning. This approach aims to optimize bone regeneration and provide innovative solutions in regenerative dentistry. Results: In silico analysis demonstrated that hDPSCs have superior osteogenic potential, consolidating them as a promising option for bone regeneration in critical defects. In addition, incorporating bone morphogenetic proteins (BMP-2) significantly accelerated the ossification processes, promoting the formation of new tissue. The integration of these advanced tools improved surgical visualization and planning, increasing the procedure's accuracy and safety. The successful application in a real clinical case validates the project's practical applicability, with a direct impact on patient health. Conclusions: This in silico analysis confirms that hDPSCs represent an effective alternative for bone regeneration in critical defects. The interaction between hDPSCs and BMP-2 enhances ossification processes, establishing itself as an innovative strategy in tissue engineering. Emerging technologies such as artificial intelligence and virtual reality improve surgical precision, demonstrating practical relevance in planning and executing customized implants. In addition, this research underscores the importance of multidisciplinary collaboration and advances personalized regenerative medicine, providing a pedagogical model for future research. Overall, it offers novel solutions in maxillofacial surgery with a significant impact on clinical practice
School social representations: senses and meanings for early childhood of the IED Antonio Nariño

Female Genital Mutilation/Cutting and the Communicative Interface Between Non-Government Organizations and the State/Policy in Egypt
No full textThis item is available only to currently enrolled UTSA students, faculty or staff. To download, navigate to Log In in the top right-hand corner of this screen, then select Log in with my UTSA ID.Global efforts to end female genital mutilation/ cutting (FGM/C) have intensified in recent decades because of the rising awareness that such a practice is an act of violence against women and girls. Numerous research articles on FGM/C have been published; however, they mostly focus on the prevalence, the medical consequences and its management. On the other hand, the field of communication which is vital in understanding and combating FGM/C has been largely overlooked or ignored. Egypt being one of the three countries, hosting more than 100 million women and girls who have been subjected to FGM/C, is also significantly understudied (as per the systematic literature review conducted by the author).
This study assessed the communicative interface between the civil society organizations and the state in Egypt in the context of FGM/C. In particular, drawing on critical theoretical perspectives, it examined the effectiveness (or lack thereof) of community based organizations vis-à-vis the prevention of FGM/C amidst the repeated changes in policy and explored the nature of the relationship between the local organizations and the Egyptian state and whether and how this relationship had been improving or hindering the process of bringing about behavioral and social change at the grassroots level. This thesis attempts to bring a fresh perspective in communication, believing that the tensions, negotiations, and conflict experienced by people and organizations in everyday life are all part of a larger concept of communication.
A total of six in-depth interviews were held with key informants working in government and local non-profit organizations. Primary and secondary sources were used for critical analysis to ensure triangulation. The emerging themes revealed tension in the relationship between the government and local organizations as apparent in the government’s recent attempt to tighten control over the operations of NGOs through a new legislation. The marriage between the state and religion is one of the key factors perpetuating an ambiguous and ambivalent stance in regards to FGM/C in Egypt. Other examples of hegemony, power and control is evident in the findings, which shed light on issues of patriarchy and the state’s submission to global governance and norms.Communicatio
Implementation of virtual reality for training workers in productive scenarios
No full textLos accidentes laborales son evidenciados como uno de los mayores problemas de la industria, ya que producen consecuencias tanto en la integridad física, mental y social de los trabajadores, así como en la productividad de las empresas. La evidencia demuestra que actuar sobre los factores de riesgo tiene una influencia significativa en la probabilidad de que ocurra un accidente; es por ello que las diferentes estrategias y herramientas para prevenir la accidentalidad laboral son un tema de interés global. Asimismo, se ha demostrado que el entrenamiento puede aplicarse bien sea para el momento de contratación de nuevos trabajadores como para la formación continua de los mismos, con el objetivo de que los conocimientos adquiridos en los entrenamientos se trasladen a la actividad laboral y permitan al trabajador un desempeño seguro y asertivo en sus labores. Las nuevas tecnologías emergen como una herramienta innovadora y poderosa para transformar el entrenamiento laboral; la realidad virtual (RV) ofrece oportunidades en la generación de espacios de entrenamiento que requieran menos tiempo, sean más efectivos y menos costosos. Sobre la base de las consideraciones anteriores, resulta beneficioso realizar una revisión de literatura que consolide el conocimiento actual sobre el uso de realidad virtual en el entrenamiento laboral, permitiendo ampliar las estrategias actuales usadas por los diferentes sectores económicos para preparar a sus trabajadores.Especialista en Seguridad y Salud en el TrabajoEspecializaciónWorkplace accidents are seen as one of the biggest problems in the industry, as they produce consequences for the physical, mental and social integrity of workers, as well as for the productivity of companies. Evidence shows that acting on risk factors has a significant influence on the probability of an accident occurring; that is why the different strategies and tools to prevent workplace accidents are a topic of global interest. Likewise, it has been shown that training can be applied either at the time of hiring new workers or for their ongoing training, with the aim that the knowledge acquired in training is transferred to the work activity and allows the worker to perform safely and assertively in their work. New technologies emerge as an innovative and powerful tool to transform job training; virtual reality (VR) offers opportunities in the generation of training spaces that require less time, are more effective and less expensive. Based on the above considerations, it is beneficial to conduct a literature review that consolidates current knowledge on the use of virtual reality in job training, allowing for the expansion of current strategies used by different economic sectors to prepare their workers
