Reading and Attention in Wharton’s Modernity and Our Own
Authors: Coit Emily
Published: October 2024

How might Edith Wharton’s thoughts about readers and reading speak to anxieties about the fate of reading in our own moment? This short article places Wharton in conversation with the contemporary thinker Maryanne Wolf, identifying some overlap and also some disagreement in their views about technology’s effects on attention, imagination, and reading. Wharton’s critical representations of readers, the essay suggests, offer a salutary reminder that fears about bad reading have long attended advances in technology; and Wolf’s hortatory account of the virtues and benefits of reading finds a proleptic critique in Wharton’s unabashed celebration of irony and pleasure.

O mapeamento do uso e cobertura territorial favorece a compreensão paisagística e as suas alterações, especialmente as decorrentes das ações antrópicas no meio físico. O presente estudo objetivou analisar o uso e cobertura da terra na bacia hidrográfica do Rio Saco (Codó, Maranhão). A área compreende a “Mata dos Cocais”, região que abrange características de biomas distintos em uma mesma escala temporal e espacial. A metodologia aplicada baseou-se em técnicas de sensoriamento remoto desenvolvidas em ambiente de Sistema de Informação Geográfica (SIG) com processamento de dados a partir do Landsat 8 e da classificação supervisionada. Os resultados mostraram uma predominância da vegetação densa na bacia em estudo, além de uma reduzida ocupação pelas classes de área urbana e corpos hídricos. A acurácia geral foi de 79%, sendo que a vegetação densa apresentou uma precisão do usuário e do produtor maior que a geral, com 91 e 87%, respectivamente. Em contrapartida, os erros de comissão e omissão mais elevados foram relativos à área urbana e corpos hídricos, o que coincidiu com as classes menos ocupadas na bacia do Rio Saco. Esses resultados são pioneiros para a mata dos cocais e fomentam dados para o planejamento estratégico de ações ambientais.
Validity theory applied to entrustment as an approach to assessment
Authors: Touchie Claire , ten Cate Olle , Park Yoon Soo , Kinnear Benjamin , Taylor David R.
Published: October 2024

In adopting entrustment-based assessments, the construct has shifted from assessing learners’ capability to provide competent care to their readiness for the responsibility for the welfare of patients and permission to perform clinical care with appropriate autonomy. Competence committees charged with making entrustment-based decisions must make decisions that are valid, fit for purpose, and interpreted appropriately. However, entrustment as a construct is complex and warrants a discussion regarding its relation to validity. While many different validity questions may be asked in the context of entrustable professional activities (EPAs), this chapter focuses on what we believe is the most salient and novel feature of EPA-based programs, which is the introduction of entrustment decision-making as an approach to assessment of health professionals in training. Validity theory, with reference to the models of Messick and Kane, is discussed in the context of entrustment. This leads to reflections on how some assumptions regarding validity may need to be reconceptualized, how sources of evidence and validity arguments can support defensible decisions, and how threats to validity must be considered and minimized.

Published: October 2024

Entrustable professional activities (EPAs) form the cornerstone of competency-based health professions education, focusing on the critical tasks trainees must master for their future unsupervised clinical practice. Recognizing the challenges in assessing EPAs, especially those caused by the rarity of some clinical events and the dynamic nature of health care settings, there is an increasing interest in utilizing simulation as a complementary approach. Using simulation modalities, educators can design controlled and relevant settings for learning and assessment, allowing students to apply theoretical knowledge, practical skills, and professional attitudes in a risk-free environment. This chapter delves into whether and how simulation can be integrated into EPA-based curricula to enhance training and preparation for performing EPAs, as well as to provide a controlled setting for assessing trainees’ entrustment levels. We explore the theoretical underpinnings for applying simulation in an EPA-based curriculum, highlighting its potential dual roles in bridging educational experiences with assessment activities, and relating both to real-world clinical practice. While we propose a model for the promising integration of simulation into EPA-based curriculum, we also note that the evidence supporting its efficacy remains preliminary. Further research must substantiate the role and value of simulation in an EPA-based training and assessment modality. Our model describes the possible application of EPAs that progresses from an individual’s basic skill acquisition to their becoming capable of acting in complex, broader team-based clinical challenges. Incorporating simulation meaningfully into EPA-based curricula represents a transformative approach in preparing health care professionals for the challenges of clinical practice.

Published: October 2024

Faculty development, trainee orientation and stakeholder engagement are essential elements of change management in the implementation of EPAs. An effective strategy addresses stakeholder needs over the various stages of planning, piloting, and implementation of EPAs. It encompasses faculty and all other stakeholders, i.e., clinical supervisors and assessors, non-workplace-based teaching faculty, coaches or advisers for trainees’ portfolios, members of clinical competence committees, administrators, program directors and other leaders. Best practices involve engaging with stakeholders as essential partners working toward a shared vision, building a sense of a community of practice, planning a range of activities in a continuous, dynamic, and enabling process, and including trainee development alongside faculty development. This chapter introduces evolving conceptions of faculty development and identifies key principles and strategies to guide the design of an effective plan. A range of approaches is outlined from passive to active, with various modes of delivery including face-to-face and hybrid and self-directed learning. Factors to consider are discussed and the significance of context is acknowledged. The importance of resourcing faculty and other stakeholders and the need to make a business case supported by ongoing evaluation are highlighted. Three examples of strategies in practice illustrate some key ideas. An analysis of the specific needs of different stakeholder groups, with potential approaches and a directory of accessible digital resources to support faculty development, trainee orientation, and engagement with other stakeholders, is also provided.
Una primera aproximación a la relación entre margen e inversión a nivel de empresa en la economía española
Authors: Puente Díaz Sergio , Mulino Ríos Maristela
Published: October 2024

Motivación

Tanto la inversión como los márgenes empresariales experimentaron una caída en 2020, pero se han ido recuperando desde entonces. La explotación estadística de microdatos empresariales permite estimar qué relación ha existido entre ambas variables en la economía española en los últimos años.

Ideas principales

•Tras la caída de 2020, los márgenes empresariales han venido aumentando en nuestro país. Este incremento se ha concentrado en las empresas que presentaban unos menores márgenes en 2019. En cambio, para las empresas con mayores márgenes antes del estallido de la pandemia, estos han mostrado, en conjunto, una evolución descendente.

•La relación entre margen e inversión, calculada a partir de datos granulares de empresa, tiene forma de U invertida: es positiva para márgenes por debajo de cierto umbral, pero se torna negativa para márgenes por encima de dicho umbral.

•En la economía española, la mayoría de las empresas se sitúan en el tramo en el que la relación entre margen e inversión es positiva. Aquellas ubicadas en el tramo en el que la relación es negativa tienden a ser, en comparación con el resto, más pequeñas, más jóvenes y más productivas.

Background: Several behavioral factors are considered to be obstacles to adopting a healthy life for those over 60 years of age; such factors have strong associations with mortality related chronic illnesses, physical inactivity, bad eating habits, and sleeping disorders. Objective:This study aimed to identify the population specific factors that affect adopting a healthy lifestyle for the elderly in Makkah, Saudi Arabia. Furthermore, this study aimed to identify possible ways to encourage the elderly into adopting a healthy life. Methods: This is a cross-sectional community-based study. Elderly Saudi citizens aging 60 years old and above were targeted. A non-random (quota sampling) sampling technique was used to recruit 330 participants. Data were collected via a structured questionnaire. Results: The Majority of participant (70 %) were in the age group of 60-66 years. Many of which (40 %) reported hypertension as the most common chronic disorder affecting them. Moreover, near half of the participants did not participate in any form of physical exercise. Additionally, fatigue was reported as the major obstacle (29%) that prevented participants from regular exercise. Conclusion:Two probable factors preventing the elderlies from adopting a healthy lifestyle were identified namely fatigue which kept older people from engaging in regular exercise and sleeping disorders which probably had an impact on overall physical health which eventually could affect their ability to participate in physical exercise.

Published: October 2024

Chromium contamination can alter genetic materials and cause hazardous health effect in life. Bio absorption method relies on the ability of biological materials to remove the heavy metals by binding metal in various ways. The bio-adsorbents consist of dead and metabolically inactive cells. The residues of banana peels can be processed and converted to be adsorbents because they have large surface areas, high swelling capacities, excellent mechanical strengths, and are convenient to use and have great potential to adsorb harmful contaminants such as heavy metals. In the present study, contaminated water was treated using the powdered peels of Musa parasidiaca, then the physico-chemical factors and the amount of chromium before and after treatment were compared in relation to winter and summer. The amount of heavy metal chromium concentration was reduced drastically. Based on the results obtained the peels of Musa parasidiaca is proved to be a low cost and effective bio-adsorbent in bioremediation of chromium.

The improper disposal of unused or expired tablets which may reach to the landfills along with the household wastes. During the present research, a pilot study has been conducted in order to know the impacts of expired and non-expired ranglim tablets on the soil quality. Organoleptic characterization and physical tests of both expired and non-expired ranglim tablets were conducted in order to know the various properties and its characteristics. During the present study, the powdered expired and non-expired ranglim tablets were added at the concentrations of 1g, 5g, and 10g to the landfill soil sample and kept for observations for 30 days. From both the treatments, the soil samples were collected and subjected to extraction and used for the analysis of various physico-chemical parameters. From the physical tests of both the tablets. It was found that, the hardness of expired ranglim tablet was 19.33g and non-expired was 6.9g. The percentage of friability of an expired ranglim was less (0.0008%) in comparison with the non-expired ranglim tablet (0.0117%). The disintegration of the expired ranglim was more than 15 hours and the nonexpired tablet got disintegrated after 10 hours. The rate of dissolution of expired ranglim was 1.05% at 4 hours. Whereas, the dissolution of non-expired drug was 98.53% at 4 hours. From the experimental results, it was observed that, in majority of the parameters, the values were found to be higher than the normal range and control values in both the treatments. Similarly, among the obtained results, the values of the expired ranglim treatments were found to have greater effect than the non-expired ones. From the study, it can be concluded that, the dissolution of expired Antidiabetic tablets can alter the soil physico-chemical properties and reduce the overall soil quality. Proper management of pharmaceuticals has to be taken care while disposing along with domestic wastes.

In India, tribal women actively participate in livelihood activities in addition to managing their homes and families. Despite putting considerably more effort than their male counterparts and significantly increasing their families’ wealth, Indian tribal women have few options to make a living. Not only when compared to the status of tribal males, but also when compared to the status of women in the general population, tribal women have terrible conditions in terms of education, employment, and health. Tribal women are still far behind despite several economic, political, and social advancements. This paper explores the situation of tribal women nationwide and discusses significant government initiatives aimed at advancing tribal women. This article highlights the traditional knowledge, sustainable methods, and obstacles faced by tribal women in India as it examines their crucial role in preventing pollution. Through initiatives like organic farming, water conservation, and forest management, tribal women have played a crucial role in environmental conservation. They face several challenges despite their enormous contributions, such as social marginalization, economic hardship, and a lack of education. The government’s efforts to empower Indigenous people and include them in environmental governance are also examined in this article. India can strengthen its efforts in sustainable development and environmental protection by fusing traditional methods with contemporary pollution control techniques and empowering tribal women via engagement in policy and education.

Reputations, relationships and refusing sex: The difficulty of saying ‘No’ and of being heard
Authors: Frith Hannah
Published: October 2024

Encouraging young women to ‘just say no’ to sex has become central to education programmes designed to delay sexual initiation and/or to prevent date rape, but little is known about the ways in which young women currently understand and experience sexual refusals. This paper draws on data fromfocus groups with 58, white, heterosexual, school and university student volunteers to explore issues around refusing sex. The transcripts of the groups were reviewed for recurrent themes (illustrated by verbatim data extracts) and a number of barriers to refusing sex were identified, including: concerns about reputation, concerns about relationships, and concerns about the effectiveness of sexual refusals. The implications for programmes designed to prevent premature sexual activity and/or date rape are discussed.
Contradicting motherhood: HIV-positive South African mothers constructing subjectivity
Authors: Long Carol
Published: October 2024

South African women diagnosed HIV-positive when they are pregnant enter into two contradictory identities simultaneously: the feared and denigrated identity of being HIV-positive and the idealised identity of motherhood. Each holds complex discursive and personal meanings and conflicts. This interview-based research focuses on South African mothers, exploring negotiations of subjectivity within these seemingly irreconcilable events, both laden with social meaning and emotional resonance. This paper introduces four dominant subject positions to emerge from discursive and psychodynamic analysis of the interviews. The first, gendered, position of HIV-positive woman and the second, ungendered and medicalised position of HIV-positive person were kept relatively separate from motherhood. Positions of motherhood are explored through the socially dominant position of mother-of-baby, in which mother’s subjectivity is secondary to that of her baby, and in relation to the less visible but more active position of mother-herself. While this position is elusive in the literature, it is present in interview data and, it is suggested, central to identities of HIV-positive motherhood. The co-existence of these four positions suggests the complexity of subjectivities of HIV-positive motherhood and the interrelation between social and personal experience.

O tucumanzeiro (Astrocaryum aculeatum G. Mey.) é uma palmeira nativa da Amazônia, com ocorrência na Bolívia, Colômbia, Guiana, Venezuela, Suriname e no Brasil. O mesocarpo (polpa) é uma camada fina de 3 mm de cor amarelada/alaranjada e gordurosa com um sabor amadeirado levemente adocicado. A casca e sementes do fruto são descartados e uma forma de aproveitar essa casca é desenvolvendo subprodutos como a farinha. O objetivo, deste trabalho foi a elaboração de pães enriquecidos com a farinha da casca do tucumã. Os tucumãs foram colhidos no campus III do Instituto Nacional de Pesquisas da Amazônia (INPA), para serem lavados e descascados para a elaboração da farinha, após caracterização da farinha da casca do tucumã (FCT), foram elaboradas três formulações, com diferentes concentrações da FCT (15%, 10%, 5%), substituindo parcialmente do trigo. Os pães foram produzidos, separando-se e pesando-se as farinhas de trigo e FCT, de acordo com cada proporção. As análises de L*(luminosidade) apresentaram um valor médio de 46,08 ± 1,03, no parâmetro a*(componentes vermelho/verde) os valores médios foram de 18,05 ± 1,6 e b*(componentes amarelo/azul) os valores médios foram de 41,14 ± 2,11. Levando em conta os valores encontrados a coloração aparente da farinha da casca de tucumã encontra-se na faixa de um amarelo acinzentado. Em relação a coloração dos pães, na qual L (luminosidade), foi possível observar na concentração de 5%, um clareamento em comparação as concentrações de 10% e 15% de farinha da casca do tucumã. Portanto, a substituição de subprodutos do Tucumã como a casca na elaboração de pães é uma boa alternativa nutricional, pois é rico em fibras e proteínas. O uso do subproduto do Tucumã, na elaboração de produtos de panificação deve ser incentivada tanto para o âmbito nutricional, econômico e ambiental. Do mesmo modo, que mais estudos sejam realizados envolvendo outras preparações e concentrações.

Para garantir uma produção sustentável na cultura do trigo, bioinsumos têm sido utilizados para favorecer o desenvolvimento das plantas e o controle de pragas e doenças. O experimento teve como objetivo avaliar o desempenho de diferentes microrganismos benéficos no tratamento de sementes de trigo em dois ambientes: laboratório e campo. O delineamento experimental foi um esquema fatorial 2x4 com 4 repetições, onde o Fator A representou o tratamento químico de sementes (A1: com e A2: sem) e o Fator D consistiu em quatro níveis de bioinsumos: D1: sem bioinsumos, D2: P.A. (Trichoderma asperellum + Trichoderma harzianum + Bacillus amyloliquefaciens), D3: coinoculação P.A. + P.B., e D4: P.B. (Trichoderma harzianum). Os componentes avaliados incluíram a qualidade fisiológica das sementes, a produtividade dos grãos e a biomassa das plântulas. A análise de variância e o teste de Scott-Knott, a 5% de probabilidade, foram realizados utilizando o software Sisvar. Os resultados indicaram que, quando os bioinsumos foram aplicados em laboratório, não houve influência significativa na qualidade fisiológica do trigo. Em relação aos componentes de produtividade, os bioinsumos também não apresentaram interferência. Contudo, os bioinsumos contribuíram para a uniformidade das plântulas, melhorando o estande de plantas e aumentando a biomassa. Observou-se que o tratamento químico de sementes impactou a ação dos microrganismos.

Dogs participate in the maintenance of leishmaniasis as a reservoir in urban areas. The Visceral Leishmaniasis Surveillance and Control Program (PVCLV) of the Ministry of Health determines the euthanasia of seroactive dogs. The human-animal relationship has become closer to the point that zoonoses are gaining greater attention from health services, and the euthanasia of these animals has an impact on the multispecies family. The maintenance of euthanasia as an action to control the disease is questioned. With the approval of medication and the development of prevention methods, guardians question the action recommended by PVCLV. This review highlights the importance of health education, environmental management, responsible custody and public policies, highlighting current legislation and its controversies, in addition to the fact that the emotional impact of euthanasia is not limited to the animal's family, but also to the professional who performs it, and that as the only action to control leishmaniasis it is ineffective and may worsen the epidemiological situation of the disease.

Clear-cell renal cell carcinoma (ccRCC) is the most common subtype of kidney cancer, accounting for approximately 75-80% of all renal malignancies. Objectives: The main objective of the study is to find the efficacy of neoadjuvant targeted therapy in the treatment of patients with localised clear-cell renal cell carcinoma. Methods: This prospective study was conducted at Mardan Medical Complex from June 2023 to January 2024. Data were collected from 85 patients.  Patients aged>18 years and have a histologically confirmed diagnosis of localized ccRCC were included in the study. Tumor size was required to be 4 cm or larger, but confined to the kidney, corresponding to Stage I to III disease. Results: Data were collected from 85 patients with an average baseline tumour size for the entire cohort was 7.5 cm, and after 12 weeks of treatment, tumours shrank to an average of 5.6 cm, resulting in a mean tumour reduction of 25%. In the sunitinib group, the tumour size decreased from 7.5 cm to 5.55 cm, reflecting a 26% reduction. Similarly, in the pazopanib group, the tumour size was reduced from 7.5 cm to 5.65 cm, with an average reduction of 24%. Conclusion: It is concluded that neoadjuvant targeted therapy, using agents such as sunitinib and pazopanib, effectively reduces tumour size and improves surgical outcomes in patients with localized clear-cell renal cell carcinoma.

Thyroidectomy is a common surgical procedure with various techniques for wound closure, including dermal staples and intradermal suturing. Each method has potential advantages and disadvantages, particularly in terms of wound complications, cosmetic outcomes, and postoperative pain. Understanding which technique offers better outcomes in these areas can guide surgeons in selecting the most appropriate method for skin closure after thyroidectomy. Objective: To compare wound complications, cosmetic outcomes, and pain scores between skin closure with dermal staples and intradermal sutures in patients undergoing thyroidectomy. Methods: A prospective study was conducted in the Surgical Department of Sheikh Zayed Hospital, Lahore, from August 2023 to August 2024. The study included 100 adult patients undergoing thyroidectomy for thyroid disease. The patients were randomly divided into two groups: Group A (n=50) received wound closure with dermal staples, and Group B (n=50) received intradermal suturing. Postoperative assessments were conducted at 1, 4, 12, and 24 weeks to evaluate wound complications, cosmetic outcomes, and pain scores. Cosmetic outcomes were measured using the Stony Brook Scar Evaluation Scale and Manchester Scar Scale. Pain was assessed using the Visual Analog Scale (VAS). Results: No surgical site infections were reported in either group. At the 24-week follow-up, cosmetic outcomes measured by the Stony Brook Scar Evaluation Scale were significantly better in Group A (4.12 ± 1.0) compared to Group B (3.32 ± 1.17) (p=0.027). Similarly, the Manchester Scar Scale score was higher in Group A (7.83 ± 1.34) than in Group B (9.20 ± 2.26) (p=0.033), indicating better cosmesis with staples. However, pain scores were significantly higher in Group A than in Group B both immediately after surgery and at the 4- and 12-week follow-ups. Conclusion: The use of dermal staples in thyroidectomy demonstrated better cosmetic outcomes and wound healing compared to intradermal suturing. However, patients who received staples experienced significantly more postoperative pain. While dermal stapling is a safe and effective alternative for skin closure, further studies with larger populations are necessary to corroborate these findings and guide clinical practice.
