Déficit, dívida e ajustamento: uma nota sobre o caso brasileiro
Authors: FRAGA NETO ARMÍNIO , RESENDE ANDRÉ LARA
Published: September 2024

RESUMO A partir da restrição orçamentária consolidada do governo é possível iluminar uma série de questões relativas à atual situação econômica do Brasil. As principais conclusões que emergem da análise são que o desequilíbrio fiscal exigirá um aumento substancial da dívida do governo em termos reais e que o impacto desse aumento nas taxas de juros pode ter consequências intertemporais explosivas e perversas. Em seguida, discutimos e descartamos a solução do “dinheiro novo (externo)” para o problema, argumentando que o Brasil não enfrenta um problema cambial, mas um problema orçamentário interno. A transferência do serviço da dívida está sendo feita, mas não pelo devedor principal, o governo. O setor privado paga a conta externa do governo e se torna o credor do governo internamente. No longo prazo, para obter equilíbrio externo e interno simultâneo, o Brasil terá de resolver o problema orçamentário interno.

ABSTRACT A study was conducted in Brazil from June to November 1999, to evaluate the efficacy of RespiSure (Pfizer Animal Health) in the control of enzootic pneumonia in a commercial swine herd. Twenty-four (24) pregnant sows were randomly allocated into two groups (T1 and T2) of 12 sows each based on expected parturition dates. Piglets from sows in T1 (131) received two IM injections of 2 mL saline solution, and piglets of T2 (133) received two doses (2 mL IM) of RespiSure on day 0 of study (between 6 to 12 days of age) and 20 days later. Piglets were weaned on day 20, and moved to grower/finisher unit on day 55 randomly assigned to 6 pens/treatment. Individual pig weights were taken on days 20, 55 and 144. Feed was weighed by pen from day 55 to 144. All pigs were slaughtered on day 145 (115 pigs in T1 and 118 in T2) and lung lesions were blindly scored during inspection at slaughter. Vaccination with RespiSure, resulted in a significant (P<0.05) lower lung lesion score (0.20% versus 2.5%), lower frequency of pigs with lung lesions (23.7% versus 57.4%), higher mean weight at slaughter (92.28 kg versus 83.96 kg), higher daily weight gain per pig (0.70 kg/day/pig versus 0.63 kg/day/pig) and better feed conversion ratio (2.527 versus 2.905) compared to control.

Resumo Este artigo analisa movimentos envolvendo processos de raciocínio matemático mobilizados por estudantes ingressantes no Ensino Superior, cursando a disciplina de Cálculo Diferencial e Integral (CDI), em discussões a partir de uma tarefa de natureza exploratória. A pesquisa é qualitativa, de cunho interpretativo e os dados recolhidos para análise são compostos por (i) protocolos contendo registros escritos das discussões e (ii) áudios das discussões nos pequenos grupos realizados em uma turma regular de um curso de Engenharia. Foram analisadas as discussões de quatro grupos, compostos por 3 estudantes em cada grupo. Os resultados obtidos evidenciaram, ao longo dos trechos de discussão dos grupos, um movimento cíclico, com avanços e recuos, de raciocinar sobre relações matemáticas e desenvolver afirmações. Os estudantes levantaram conjecturas e, ao conjecturar, foram identificados três movimentos distintos, que são: (i) abandonar conjecturas definitivamente ou provisoriamente; (ii) refutar tais conjecturas com justificativas, ou sem justificativas; ou ainda (ii) aceitar as conjecturas buscando reconhecer e explicar a validade (ou não) dessas afirmações justificando. Em alguns momentos, esse movimento culminou com o estender, para situações mais gerais, as regularidades observadas em casos particulares, que conduziu ao processo de generalizar.

Resumen Ante la necesidad de desarrollar investigaciones que informen sobre elementos clave para mejorar los programas de actualización en la enseñanza de las matemáticas a través de la modelación, se llevó a cabo una investigación cualitativa, longitudinal, basada en un estudio de caso. El trabajo se enfoca en el análisis de la evolución del sistema conceptual de un profesor de matemáticas, al estar inmerso en un programa de actualización docente enmarcada en la perspectiva de modelos y modelación. Para este estudio se diseñó un programa de actualización docente multiestratos, el cual involucró interacciones entre estudiantes, profesor e investigadores. El programa se enfocó en promover la evolución del sistema conceptual del profesor al diseñar, implementar y evaluar una secuencia de desarrollo de modelos orientada a apoyar el aprendizaje de la función exponencial en estudiantes universitarios de primer semestre. Los sistemas conceptuales generados por el profesor se caracterizaron con base en tres dimensiones: instruccional, de contenido matemático e histórica. El análisis multidimensional permitió identificar que al participar en el diseño e implementación de una secuencia de desarrollo de modelos el profesor se involucró en procesos de refinamiento iterativo entre el diseño de la secuencia, y las dimensiones de su sistema conceptual. Además, se concluyó que el enfoque multiestratos puede ser un medio para promover la evolución del sistema conceptual de un profesor.

Simbologia matemática para o conceito de limite dos séculos XVIII ao XX
Authors: Silva da Silva Circe Mary
Published: September 2024

Resumo O objetivo deste estudo é identificar e comparar os símbolos propostos para o conceito de limite, a partir da análise de livros e artigos científicos de matemáticos e autores de livros de matemática do século XVIII ao século XX. O ano de 1786 é o marco inicial com a identificação do primeiro símbolo de limite e depois o de 1905, marco final, quando este se estabilizou. A metodologia seguiu os seguintes passos: revisão da literatura com destaque aos trabalhos de Cajori; seleção dos textos originais dos autores citados por Cajori; ampliação das fontes com outros autores selecionados; e análise comparativa dos símbolos de limite. Concluiu-se que, durante esse período, houve interesse por parte de alguns matemáticos em justificar o uso de um símbolo para este conceito, que os símbolos sofreram modificações, alguns foram abandonados e, após o início do século XX, não surgiu nenhum símbolo adicional para este conceito.

Dynamics of Eustrongylidosis in Fishes in the Zaporizhzhia (Dnipro) Reservoir, Ukraine
Authors: Yesipova N. B. , Sharamok T. S. , Marenkov O. M. , Sydorenko V. S. , Shmyhol N. V.
Published: September 2024

The parasitic nematode Eustrongylides excisus, Jagerskiold, 1909 (Dioctophimida: Dioctophimidae) is widespread and zoonotic. 23 fish species were studied in view of infestation by this parasite. The maximal infestation with
E. excisus larvae were recorded in seven years after the first detection of the parasite in the reservoir in 2008. Maximal infestation rate was found in the monkey goby (90%, 8.5±0.93 spec/ind) and the common perch (79%, 17.2± 1.53 spec/ind). In pike and pikeperch, the infestation rates were half as low.

In other fishes (European catfish, Eurasian daces, Prussian carp, White bream), the parasite occurred sporadically with the maximum infestation extension from 3.2 to 13.6%. The dynamics of fish eustrongylidosis in the Zaporizhzhia (Dnipro) reservoir was characterized by the following stages: increase
(2008-2013), maximum development (2013-2018), and decline (2018-2023) of infestation rates. The spatial distribution of E. excisus was characterized by high
density of infested fishes in the lower section of the reservoir owing to accumulation of silt deposits and intensive development of oligochaetes in them, which are the first intermediate hosts of the parasite. We suppose, that the decline in the infestation rates decrease in the Zaporizhzhya (Dnipro) reservoir is temporary, as the reservoir provides favorable conditions for the parasite's development cycle:
progressive eutrophication and siltation; presence of intermediate and paratenic hosts; favorable conditions for the cormorants nesting - the ultimate hosts of eustrongylids.
Casein as a foaming agent in cement-treated soil for lightweight embankments
Authors: Nakayenga Joyce , Hata Toshiro
Published: September 2024

Construction of lightweight foamed cement banking embankments usually requires temporary sites for air-pressure machinery. This study proposes casein, a milk protein, as an additive in cement-treated soils for constructing lightweight embankments to reduce milk waste and the necessity for air pressure machinery. The effects of mixing time, casein content (0%–8%), and cement quantity (100 and 150 kg/m3) on the dry density, unconfined compressive strength, and coefficient of permeability of cement-treated soils were determined. Furthermore, the durability of the cement-treated soils mixed with casein to wet and dry cycles and its impact on the pH of water was determined. It was established that adding 5% of casein to cement-treated soils and mixing for 10 min produced lightweight embankment materials with complaint strength (>300 kPa), durability and permeability (10−3 cm/s), minimal environmental impact, and promoted sustainability.

Published: September 2024

Industrial solid waste is used as a supplementary cementitious material (SCM) to replace cement, promoting the recycling and improving resource and economic sustainability. In this study, an organic combination of SCMs was prepared, along with the preparation of composite cementitious materials (CCM) that can be tailored to the aluminum sulfate alkali-free liquid accelerators. The findings revealed that a combination of 30% SCMs, including 10% slag, 15% silica fume, and 5% treated hardened cement powder (T-HCP), was blended with cement to form a CCM. Under the influence of the accelerator, the initial setting time of CCM is 1 min 20 s and the final setting time of CCM is 3 min. The compressive strength at 1, 3, and 28 days reaches 17.2, 29.9, and 51.6 MPa, respectively. CCM can utilize SiO2 from silica fume and CaCO3 in T-HCP as the nucleus to facilitate the substantial generation of AFt and Ca(OH)2 in the initial stage. It can be seen that the use of SCM together with alkali-free liquid accelerators in shotcrete not only enables the utilization of solid waste but also greatly improves the performance of shotcrete.
Centrifuge tests on the consolidation behaviour of foundations under alternating loads
Authors: Ganal Aljoscha , Reul Oliver , Jacobsz S. W.
Published: September 2024

This paper presents the results from centrifuge tests on raft foundations and piled rafts in overconsolidated kaolin clay carried out in a beam centrifuge at the University of Pretoria. The foundations were subjected to unloading and reloading phases as well as to multiple consecutive groundwater drawdowns, simulating typical loading scenarios of structures in an urban environment. In order to investigate the time-dependent load-deformation behaviour of foundations, the settlement of the foundations, the pore water pressures at different depths and the axial strains in the piles, from which pile resistances were then derived, were measured continuously. In the tests, repeated groundwater drawdowns resulted in a settlement accumulation, with the increase in settlements decreasing with each repetition. The pile position within the pile group was found to have a major impact on the mobilised pile resistance. The position, however, became less significant as the load level increased. Furthermore, insights were gained concerning the load distribution within piled rafts during consolidation.

Published: September 2024

Road congestion pricing (RCP) is an important way of controlling traffic congestion from the perspective of traffic demand management. This paper introduces the concept and four main types of applications of RCP, summarises the development of RCP theory, reveals the first- and second-order effects of RCP on transportation systems and land use, and analyses the long-term impact of RCP on the spatial location structure of land use. Relevant research progress considering land use effects is systematically and comprehensively reviewed from three research perspectives: demand modelling (pre-RCP), monitoring and analysis (post-RCP) and modelling methods (integration models and other models). The results showed that RCP will affect residents’ travel behaviour in the short term and will lead to changes in spatial location decisions in the long run, thus creating new travel demands and travel modes, affecting the transportation system and urban spatial patterns again. Implementing cordon charges has an agglomeration effect on the population in city centres. Cordon charges also have a significant negative impact on businesses in the toll area and a dispersive effect on jobs. Combined with appropriate strategies for shared autonomous vehicles, RCP can simultaneously improve transportation efficiency and regional accessibility.
Moralism as a Dualism in Ethics and Politics
Authors: Queloz Matthieu
Published: September 2024

What is it that one fundamentally rejects when one criticizes a way of thinking as moralistic? Taking my cue from the principal leveller of this charge in philosophy, I argue that the root problem of moralism is the dualism that underlies it. I begin by distinguishing the rejection of moralism from the rejection of the moral/nonmoral distinction: far from being something one should jettison along with moralism, that distinction is something that any human society is bound to develop. But this valuable distinction is transformed into a problematic dualism when it casts the two sides of the distinction as contrasting sharply in nature, value, and structure. In ethics, the resulting dichotomy takes the form of a dualism of morality and prudence. In politics, it takes the form of a dualism of principle and interest. I explain the enduring appeal of such dualisms before laying out the costs of moralism thus conceived: moralism erodes our sensibility to the moral and political costs of value conflicts; it projects an unrealistic conception of agency that sets up scepticism about responsibility; and it limits our ability to appreciate and realize the wider variety of nonmoral values that sustain us, our achievements, and morality itself.

A Robust and Rapid Grid-Based Machine Learning Approach for Inside and Off-Network Earthquakes Classification in Dynamically Changing Seismic Networks
Authors: Annunziata Daniela , Savoia Martina , Martino Claudio , Giampaolo Fabio , Convertito Vincenzo , Piccialli Francesco , Beroza Gregory C.
Published: September 2024

Earthquake location and magnitude estimation are critical for seismic monitoring and emergency response. However, accurately determining the location and the magnitude of off-network earthquakes remains challenging. Seismic stations receive signals from various sources, and it is crucial to quickly discern whether events originated within the area of interest. Location determination relies on obtaining ample P- and S-wave readings to ensure accurate and dependable results. Seismic networks vary due to station changes or outages, and their variable geometry represents a constraint for traditional machine learning models, which rely on fixed data structures. This study presents a novel approach for real-time classification of local and off-network earthquakes using the first three associated P picks within an early warning scenario, and also identifying the event’s direction. To handle variable network geometry, we employ a grid structure over the seismic area. The effectiveness of our method was initially validated with data from the Italian National Seismic Network, selecting Central Italy and Messina Strait subnetworks, and from a subnetwork of the Southern California Seismic Network; it achieves an inside–outside accuracy of 95%, 93%, and 96%, and a location region accuracy of 93%, 82%, and 97%, respectively. Its robustness was further demonstrated using picks from an earthquake early warning (EEW) system, the PRobabilistic and Evolutionary early warning SysTem (PRESTo) software, to simulate real and noncataloged input data. Our method outperforms PRESTo’s first localization, showing an inside versus outside classification improvement of 9.1% for Central Italy and 20.7% for the Messina Strait. This approach provides advanced seismic monitoring that can be implemented in systems devoted to reduce the impact of damaging events as the EEW system, but also shows promise for enhancing emergency response. Indeed, being able to quickly classify earthquakes is crucial for responding promptly and effectively during emergencies, minimizing risks, and for limiting false alarms.
Statistical Analysis of Characteristic Parameters and Probability Distribution of Near-Fault Velocity Pulses—A Case Study on the 1999 Mw 7.6 Chi-Chi Earthquake
Authors: Ji Zhiwei , Li Zongchao , Zhang Yan , Quanbo Luo , Sun Jize , Ju Changhui , Zhang Yongxian
Published: September 2024

The 1999 Mw 7.6 Chi-Chi earthquake in the Taiwan region generated valuable ground motions, providing an opportunity for studying the characteristic parameters and distribution of near-fault velocity pulses. Using the finite-difference method, we built a source model, simulated the 1999 Mw 7.6 Chi-Chi earthquake ground motions, and obtained synthetic velocity waveforms consistent with the observed waveforms. On this basis, we analyzed the distribution of velocity pulses in the near-fault region and compared it with the pulse probability distribution (PPD) curve of the near-fault velocity pulse. We found that the complex rupture process of the Mw 7.6 Chi-Chi earthquake resulted in velocity pulses still being recorded in Miaoli and Xinzhu. In addition, we analyzed the relationship between pulse period, pulse peak, and fault distance. The pulse peak indicates a clear attenuation trend with increasing fault distance (Rrup) and no statistical relationship between the pulse period and Rrup. More velocity pulses in normal-fault components reveal the reverse fault of the Chi-Chi earthquake. Finally, structures with natural periods within the 1–7 s are more susceptible to resonance from near-fault velocity pulses, and it is necessary to take appropriate seismic measures. This study lays the foundation for a deeper understanding of the ground motion and pulse characteristics caused by earthquakes and contributes to sustained efforts in seismic hazard assessment.
Waveguide or Not? Revised Ground-Motion Simulations for Greater Los Angeles from the M 7.8 ShakeOut Earthquake Scenario
Authors: Yeh Te-Yang , Olsen Kim B.
Published: September 2024

The ShakeOut scenario of an M 7.8 northwestward rupture on the southern San Andreas fault (SSAF) (Jones et al., 2008) predicted significant long-period ground-motion amplification in the greater Los Angeles, California, area, caused by a waveguide from interconnected sedimentary basins. However, the early ShakeOut ground-motion simulations omitted important model features with immature versions of the velocity structure and fault geometry. Here, we present 0–1 Hz 3D numerical wave propagation simulations for the ShakeOut scenario including surface topography, as well as updated high-resolution velocity structures and SSAF geometry. Spectral accelerations at 3 s are increased by the local high-resolution basin models (25%–45%) but decreased from complexity in velocity and density updates outside the basins (65%–100%) and inclusion of surface topography (∼30%). The updated model reduces the simulated long-period ground motions in the waveguide by 60%–70%, bringing the predictions significantly closer to the values by a leading Next Generation Attenuation-West2 ground-motion model.

Objetivo: Evaluar el manejo y éxito del tratamiento de las litiasis ureterales inferiores en el Hospital de Clínicas. Materiales y métodos: Estudio retrospectivo, descriptivo y observacional no probabilístico de casos consecutivos que incluyó a 31 pacientes diagnosticados con litiasis ureteral inferior. Se utilizaron técnicas como ureteroscopía, meatotomía y ureterolitotomía por incisión de Gibson. Se evaluó la tasa de éxito y complicaciones de cada procedimiento. Resultados: La tasa de éxito fue del 93% para ureteroscopía, 83% para ureterolitotomía y 100% para meatotomía/enfoque combinado. El uso de catéter tipo doble J fue mayor en los abordajes abiertos. El tiempo de recuperación postoperatoria fue menor para las técnicas endourológicas. Conclusiones: Todas las técnicas demostraron ser efectivas en el manejo de las litiasis ureterales inferiores. Las técnicas endourológicas ofrecen ventajas en términos de menor tiempo de recuperación y menor necesidad de catéteres. La elección del procedimiento debe considerar factores individuales del paciente y la disponibilidad de recursos.
Responsabilidad social universitaria: Retos para un entorno desafiante
Authors: Cardona-Arbeláez Diego
Published: September 2024

El tema de la Responsabilidad Social Universitaria ha estimulado un debate tanto al interior como al exterior de las instituciones de educación superior, toda vez que las universidades son las llamadas a un jugar un importante rol en la transformación social, económica y ambiental.
En Latinoamérica, las primeras aproximaciones sobre el significado de Responsabilidad Social Universitaria (RSU) la ofrecieron el filósofo y académico François Vallaeys, que plantea que la responsabilidad social de las Universidades demanda una coherencia institucional permanente en todos sus procesos organizacionales, una congruencia entre el decir y el hacer sea un su plan curricular, desarrollo profesoral, las líneas de investigación, sus programas de extensión enmarcadas en las tres funciones sustantivas de la educación que son docencia, investigación y extensión y sus impactos sobre la sociedad (Vallaeys, 2014).
Así mismo, otros académicos como Ricardo Gaete Quesada y Carmen De la Calle plantean la necesidad en primera instancia para definir un concepto más claro y homogéneo sobre el significado de la RSU y su contribución a la transformación social a partir de un mayor compromiso de las universidades con su entorno, que involucre un cambio de paradigma desde las funciones sustantivas de la Universidad (Gaete, 2015; De la Calle, 2011)...
Combination bleaching technique for an aesthetic upgrade in vital teeth- A case report of two cases
Authors: Choudhary Ekta , Banati Mallika
Published: September 2024

Teeth stains can broadly be classified into two types; Extrinsic and Intrinsic stains, the latter being harder to remove. The etiology of discolouration is vast which could be due to diet, medication, fluorosis or any systemic illness. Extrinsic stains are mainly on the outer surface of the tooth (Ex: Tea stains, Tobacco stains) and Intrinsic stains are present mainly within the tooth structure (Ex: systemic stains, fluorosis). Tooth bleaching is a cosmetic dental procedure aimed at improving the aesthetics of the smile and thereby increasing the patient satisfaction. This case report documents the successful application of a combination therapy for vital tooth bleaching by using walk in bleach as well as laser bleaching for the patients aesthetic considerations

Published: September 2024

The idea of opening military classes refers to the tradition of national defense education, training the young generation to defend the homeland and strengthening the country's ties with the army. The creation of military classes became a precedent for the Ministry of National Defense and the Ministry of National Education to build a common defense education system for high school students. The task of military classes in Polish high schools is to prepare young people for future service in various services, such as police, fire brigades and other special services. The aim of this work is to capture the relationship between body composition components and physical fitness of selected uniformed groups. The body composition components were analyzed with the help of the Tanita Body Composition Analyzer DC-240MA. The study used tests from the Polish Army physical fitness test, the Beep test and barbell bench press while lying on a straight bench. One of the conclusions obtained was that the correlation between body composition and fitness tests showed that higher levels of body fat, lean body mass, BMI and body weight negatively affect the results obtained in pull-ups, trunk bends, shuttle runs and Beep tests.

This study aimed to investigate the bilateral kinematic differences in temporal variables between the Dominant and Non-dominant legs in the roundhouse kick of college-level women practicing Taekwondo. Four male athletes with black belts volunteered to participate in the study. Participants were instructed to perform five kicks with each leg after visual stimuli at maximal velocity allowing 30-s passive recovery time between each kick. Reaction time, movement time, and attack time in the roundhouse kick were assessed using video cameras and force platforms for both the dominant and non-dominant legs. The analysis revealed no significant differences in reaction times (0.15 ±0.03 and 0.15 ±0.04 s, n=20), movement times (0.62 ±0.06 and 0.64 ±0.04 s, n=20), or attack times (0.77 ±0.09 and 0.79 ±0.06 s, n=20) for the dominant and non-dominant legs (p>0.05). However, a bilateral dominance was observed, consistent with the sporting level of the participants. These results support the training regimen both-guards oriented equally to improve overall performance in Taekwondo.

Published: September 2024

Background: The etiology of autism spectrum disorders is not well known but oxidative stress has been suggested to play a pathological role.
Purpose: The present study aimed to investigate the effects of supervised physical exercise on oxidative stress in children with autism.
Methods: Thirty boys with autism (7 to 9 years old) voluntarily participated in this study. They were randomly divided into experimental and control groups. The experimental group performed a physical curriculum known as sports, play and active recreation for kids (SPARK) for 12 weeks (3 sessions of 45 minutes per week), while the control group was exempted to participate in the program. As the clinical parameters, the level of brain-derived neurotrophic factor (BDNF) and malondialdehyde (MDA) were measured before and after the intervention.
Results: The results indicated that BDNF levels significantly increased (85.7 %) and MDA concentration significantly decreased (29.2%) in the experimental group (p < 0.05).
Conclusions: In conclusion, the supervised physical exercise may result in less oxidative stress in children with autism.

Published: September 2024

Rugby is a popular sport and requires participants to have commensurate physical attributes for effective participation. One physical fitness test battery which enjoys extensive use contextually is the European Test of Physical Fitness (Eurofit). However, the psychometric properties of the test battery have not been explored and documented in the local context. Therefore, this study was conducted to examine the test-retest reliability of the Eurofit test battery items among elite schoolboy rugby players in Harare, Zimbabwe. Thirty-two (32) players with the mean age of 17.2 (SD=1.03) years completed all the tests during the in- season period. Anthropometric and Eurofit test measurements were obtained twice with seven days separating the assessments. The Intraclass Correlation Coefficient (ICC) estimated the reliability test items. The global ICCs for the Eurofit test items ranged from 0.59 to 0.98. The Sit-and-Reach test yielded the highest temporal reliability (ICC=0.98). The Plate Tapping test, Flamingo Balance test and 10×5m Shuttle Run test showed ICCs < 0.7. Cognisant of the study limitations, some component test items of Eurofit test battery can be recommended for reliably evaluating aspects of physical fitness in junior rugby players in Zimbabwe whilst others still need consideration and test modification.
Assessing Jamaica's Logistics Hub Initiative and Its Implications for Sustainable Development
Authors: Reid Shemar , Johnson Corey
Published: September 2024

This study looks at the Jamaica Logistics Hub Initiative (JLHI), a deliberate initiative to convert Jamaica into a major participant in global commerce and logistics. Using a mixed-methods approach, the study examines economic indicators, environmental consequences, and alignment with sustainable development objectives from 2010 to 2022, including time periods prior to and following the initiative's 2013 first appearance. The findings show considerable economic benefits, such as faster GDP growth, higher foreign direct investment, and job creation in logistics-related industries. However, the report notes several problems, notably in terms of environmental sustainability and the need to improve export competitiveness. The JLHI's connection with the SDGs is reviewed, highlighting positive contributions to economic growth and global alliances, while recognizing opportunities for improvement in the management of the environment. The study concludes that the JLHI's long-term performance is dependent on combining economic goals with environmental sustainability and social equality. Recommendations include improving logistical performance, creating value-added services, introducing green technology, and prioritizing workforce development. This thorough research provides useful insights for policymakers and stakeholders, adding to the current discussion on sustainable logistics hub development in small island developing states.
Positivism and Qualitative Nursing Research
Authors: Paley John
Published: September 2024

Despite the hostility to positivism shown by qualitative methodologists in nursing, as in other disciplines, the epistemological and ontological instincts of qualitative researchers seem to coincide with those of the positivists, especially Bayesian positivists. This article suggests that positivists and qualitative researchers alike are pro-observation, pro-induction, pro-plausibility and pro-subjectivity. They are also anti-cause, anti-realist, anti-explanation, anti-correspondence, anti-truth. In only one respect is there a significant difference between positivist and qualitative methodologists: most positivists have believed that, methodologically, the natural sciences and the social sciences are the same; most qualitative researchers are adamant that they are not. However, if positivism fails as a philosophy of the natural sciences (which it probably does), it might well succeed as a philosophy of the social sciences, just because there is a methodological watershed between the two. Reflex antagonism to positivism might therefore be a major obstacle to understanding the real reasons why qualitative research and the natural sciences are methodologically divergent; and less hostility on the part of qualitative nurse researchers might bring certain advantages in its wake.

Relevance and Purpose: Previously, we proposed a method for assessing the osmotic resistance of erythrocytes (ORE), based on determining the number of hemolyzed erythrocytes during their strictly fixed exposure in distilled water containing 2.5 mM CaCl2. This method has shown that as the duration of exposure increases (30, 45, 60, 90 and 120 s), the percentage of hemolyzed erythrocytes increases.

Penelitian ini bertujuan untuk menginvestigasi bagaimana guru agama Islam di SMPN 08 Palembang mengembangkan sikap toleransi beragama di kalangan siswa, serta untuk mengeksplorasi faktor-faktor yang mempengaruhi perkembangan sikap tersebut. Penelitian ini menggunakan metode penelitian lapangan dengan pendekatan deskriptif kualitatif. Lokasi penelitian dilakukan langsung di SMPN 08 Palembang, dengan subjek penelitian terdiri dari guru agama Islam yang mengajar di sekolah tersebut dan siswa kelas VII. Teknik pengumpulan data yang digunakan meliputi observasi, wawancara dengan guru dan siswa, serta dokumentasi terkait kegiatan pembelajaran dan interaksi di sekolah. Hasil penelitian menunjukkan bahwa: (1) Peran guru agama Islam dalam membentuk sikap toleransi beragama siswa melibatkan berbagai strategi dan pendekatan. Guru tidak hanya menanamkan nilai-nilai seperti persaudaraan, penghargaan, dan rasa hormat terhadap sesama, tetapi juga memperkuat nilai-nilai kerjasama, solidaritas, tenggang rasa, tanggung jawab, serta kasih sayang pada siswa. Pendekatan yang digunakan guru agama Islam dalam mengembangkan sikap toleransi meliputi penggunaan metode keteladanan, nasehat, pendekatan, dan pembiasaan. Metode ini diterapkan baik di dalam maupun di luar kelas untuk memberikan contoh nyata dan memberikan pemahaman yang mendalam kepada siswa tentang pentingnya toleransi beragama. (2) Faktor pendukung dalam pengembangan sikap toleransi antara lain adanya kekompakan di sekolah dan kerjasama yang baik antara sekolah dengan orang tua siswa. Guru juga memiliki peran penting sebagai contoh dalam menunjukkan toleransi antar umat beragama kepada siswa. Namun, terdapat juga faktor penghambat seperti pengaruh lingkungan dan media yang kurang mendidik, serta perbedaan sudut pandang antara siswa. Oleh karena itu, diperlukan upaya kolaboratif antara sekolah, guru, dan orang tua untuk mengatasi tantangan ini demi menciptakan lingkungan belajar yang inklusif dan toleran.
