Global urban humanity – the “embodiment” of embodying peripheries
Authors: Hwa Kuan
Published: February 2023

Human "embodiment" is a polysemous term that has rich multi-, inter-, and transdisciplinary dimensions from various histories of consciousness. As a paradigm for various methodologies, it emphasizes the lived experience and the immanence of the human condition, especially regarding sensory habitus, bodily ways of knowing, and the material-social dimension of humanity within a historically/geographically situated context; it validates all people as bearers of their own insight and knowledge, and emphasizes that experience itself serves as a phenomenological basis for understanding. Embodiment is thus not reducible to an abstract philosophical project, but rather holds possibilities for a practical and applied ethics. In the context of peripheries, embodiment can be understood as the commitment to marginalized communities and teaches us both the scientific and humanistic value of compassion.
Durumi Camp, Abuja: conflict and the spatial praxes of a furtive-periphery
Authors: Àjàdí Stephen
Published: February 2023

The current situation of conflict in Northern Nigeria in the past decade has been responsible for more displacement than in the region’s previous recorded history. According to the Global Terrorism Index, Nigeria is the most terrorised country in Africa and the third most terrorised on the planet. The UNHCR and IDMC estimate over 3.2 million people displaced in the region with 2.58 millions of them scattered internally. The consistency of these conflicts has given rise to a perpetual process of internal displacement and rare forms of peripherality. IDP/Refugee camps are most often treated as periphery—appendices to the script of the city. As peripheries, IDP camps and informal settlements in various cities in the north are constantly faced with a pressing need to develop resilience for just surviving. There are currently no significant research attempts to study these resilience characters. The research focuses on the socio-spatial praxes of Durumi (Area 1) camp towards resilience. Durumi Camp is a rather surreptitious periphery sandwiched in a middle-class area in the city of Abuja in Nigeria. Using a mixed approach of ethnography, digital spatial analyses, and architecture, the new lives of the campers are studied in their simple but sophisticated adaptations to the dynamics of their new social and physical environment. The findings of the spatial study engage and further raise new questions and notions of the periphery in terms of socio-spatial compatibility, movement, re-enactment and re-invention of socio-spatial practices and cultures in African urbanity. The study also displaces the current theories of the periphery that describe it as fully dependent on the city center in terms of innovation. The study is a product of three years of ethnographic field work and spatial study in the area. It helps expand the discourse of the center and periphery in the context of conflict, displacement, and vulnerability.
Fikirtepe in limbo: urban transformation, cross-border migration, and re-peripheralization in Istanbul
Authors: Pasta Francesco
Published: February 2023

The historical development of Istanbul’s gecekondu areas (informally-originated neighborhoods) can be broadly interpreted as a progression toward the center and subsequent re-peripheralization, both in sociopolitical terms and in actual urban geography. While Istanbul emerged in recent decades as a magnet for transnational migrants and for capitals pouring into the debt-fueled real estate sector, many such neighborhoods have been targeted by speculative socio-spatial restructuring projects, while also absorbing much of the migratory influx. The recent economic crisis plunged these urban redevelopment sites into a deadlock, generating a fragmented urbanscape in which multiple layers of uncertainty, suspension, and informalization overlap and interact. This chapter explores the unfolding transformation in Fikirtepe, the largest ongoing redevelopment project in the city, which has seen its social and urban fabric torn apart by the redevelopment and is currently stuck in an unstable but protracted limbo. As Fikirtepe becomes “unlivable” for many of its long-time dwellers, a number of migrants are moving in, etching out a living: a collateral effect of redevelopment failure, creating a space of opportunity for new disenfranchised populations with varied backgrounds, legal statuses, and life trajectories. Within this setting, this chapter analyzes the periphery as a condition that is articulated, reproduced, and transformed through embodied practices. With their practices, narratives, and trajectories, those who inhabit such botched urban transformation embody different layers of the periphery, contributing to shape an understanding of it as a perspectival condition with a polyvalent spatiality and temporality.

The Effect of Stress Ratio on Fatigue Cracks Growth Rate in Aluminum Alloy
Authors: Karash Emad Toma
Published: February 2023

The financial and societal consequences of the sudden failure of various mechanical structures and components can occasionally be severe. As a result, there has been extensive research done on fatigue failure in both the scientific and industrial fields. The impact of stress ratio adjustments on the rates of fatigue fracture propagation for an aluminum alloy has been investigated in the current study. This aluminum alloy was extracted from a Russian MI25 helicopter's primary blade. The stress intensity factor was calculated and employed by creating an initial crack in the test specimens after a specimen of MI25 blade was cut into testing specimens with standard dimensions. A special program was written specifically for this purpose to draw a graph of the stress intensity factor range (k) with value of the propagation of fatigue cracks (da / dN) at each stress ratio (R); Propagation of fatigue cracks has been studied. Finally, the relationship between the two different stress ratios has been discovered. Between the two, a comparison has been established. The findings indicated that when the stress ratio rises, so too does the rate at which fatigue cracks form. Conversely, with a negative stress ratio, the negative increase leads to a reduction in the rate at which fatigue cracks grow. The data have been examined, and during the second stage of crack propagation, where (R = 0.0), pertinent equations that are compatible with the Paris equation have been discovered.

Published: February 2023

This articles discusses the researches in Uzbekistan on the study of our heritage stored in large museums and libraries of Turkey. The history of Uzbekistan contributes a special role and specific feature in the pages of the history of world civilization. The spiritual and material heritage of Central Asia has become one of the brightest parts of world culture. Science, architecture, fine and applied arts, literature, poetry, and music have formed themselves a remarkable and breathtaking condition around the world, which in turn indisputably testifies not in vain to name particular eras as “Renaissance” in various countries. However, it can be regrettably stated that many cultural monuments, material objects and cultural works of the Uzbek people have been taken away from our country for various reasons. On the one hand, this fact is piteous in terms of forfeiture and deprivation, and on the other hand, their storage and finding in other countries in undamaged form is awesome. Under this pretext, the great culture of the Uzbek people has been widely known outside Uzbekistan.

Insight into oral amphiphilic cyclodextrin nanoparticles for colorectal cancer: comprehensive mathematical model of drug release kinetic studies and antitumoral efficacy in 3D spheroid colon tumors
Authors: Ünal Sedat , Varan Gamze , Benito Juan M , Aktaş Yeşim , Bilensoy Erem
Published: February 2023

Colorectal cancer (CRC) is the third most diagnosed cancer type globally and ranks second in cancer-related deaths. With the current treatment possibilities, a definitive, safe, and effective treatment approach for CRC has not been presented yet. However, new drug delivery systems show promise in this field. Amphiphilic cyclodextrin-based nanocarriers are innovative and interesting formulation approaches for targeting the colon through oral administration. In our previous studies, oral chemotherapy for colon tumors was aimed and promising results were obtained with formulation development studies, mucin interaction, mucus penetration, cytotoxicity, and permeability in 2D cell culture, and furthermore in vivo antitumoral and antimetastatic efficacy in early and late-stage colon cancer models and biodistribution after single dose oral administration. This study was carried out to further elucidate oral camptothecin (CPT)-loaded amphiphilic cyclodextrin nanoparticles for the local treatment of colorectal tumors in terms of their drug release behavior and efficacy in 3-dimensional tumor models to predict the in vivo efficacy of different nanocarriers. The main objective was to build a bridge between formulation development and in vitro phase and animal studies. In this context, CPT-loaded polycationic-β-cyclodextrin nanoparticles caused reduced cell viability in CT26 and HT29 colon carcinoma spheroid tumors of mice and human origin, respectively. In addition, the release profile, which is one of the critical quality parameters in new drug delivery systems, was investigated mathematically by release kinetic modeling for the first time. The overall findings indicated that the strategy of orally targeting anticancer drugs such as CPT with positively charged poly-β-CD-C6 nanoparticles to colon tumors for local and/or systemic efficacy is a promising approach.
Soviet Politics of Memory in Southern Bessarabia and Northern Bukovyna: Representation of the Past and Mythmaking during World War II
Authors: Drozdov Viktor
Published: February 2023

The incorporation of new territories into the Ukrainian SSR during World War II required reconstructing the local community’s identity and shaping its historical memory through Stalinist ideology. This article examines the features of Soviet memory politics in Ukrainian territories through the examples of Southern Bessarabia and Northern Bukovyna, which were annexed in 1940 due to the military campaign against Romania. The study’s objectives were to determine the influence of Soviet ideology on the representation of the past, characterize the ways that the official memory was shaped during World War II, and analyze historical myths that spread throughout the official and historical discourse. The main historical images, which Soviet ideologists formulated in
official statements, historical works, and propaganda in periodicals, have been extracted using historical discourse analysis. Comparative historical analysis has identified similarities and differences in interpreting the above-mentioned regions’ pasts. It is pointed out that the historical arguments and concepts used by the Soviet power to justify the annexations became the foundation for the historical discourse. The article analyzes the introduction of the myth of “longsuffering lands” into historical narratives, which interpreted the Soviet territorial conquests as the liberation of oppressed peoples. It has been established that the representation of Southern Bessarabia and Northern Bukovyna’s pasts corresponded to the Soviet concept of “Ukrainian people’s reunification.” However, the distinction between these regions’ ethnic composition and historical development influenced the politics of shaping historical memory.
The role of the national biosafety advisory council in the system of countering the challenges of the biological nature of France
Authors: Velichko Mykola
Published: February 2023

The article examines the role of the National Advisory Council (hereinafter — the Council on Biosafety of France) and the legal support of its activities in order to use the positive experience of this country for Ukraine. The necessity of this study was the fact of updating and approval according to the Decree of the President of Ukraine № 560/2020 of 10.12.2020 of the personnel of the Commission on Biosafety and Biological Protection under the National Security and Defense Council of Ukraine. In addition to updating and approving the specified personnel of the Commission on Biosafety and Biological Protection, the regulatory framework for its activities has not been developed and adopted.

Given the European integration direction of Ukraine, it is important to study and use the experience of such consultative organizations in the EU. Among the progressive EU countries in this regard is France. The motivation for choosing to study the legal basis for ensuring the activities of the National Advisory Council on Biosafety in the biosafety and biosecurity system of France was the following:

— France is one of the economically developed countries of the EU; — in France, one of the highest world levels of development of medical and biological science and technology, especially in epidemiology; — The National Biosafety Advisory Board in the French biosafety and biosecurity system is effective. In addition, France is the depositary of the Geneva Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Similar Gases and Bacteriological Agents (Geneva, 17 June 1925), kept in the diplomatic archives of the Ministry of Europe and Foreign Affairs.

Based on the study of regulatory support (Decree signed by the Prime Minister of France № 2015—1095 of 31 August 2015) of the National Advisory Council on Biosafety in the biosafety and biosecurity system of France, the following conclusions were made: — France has established an effective advisory board, provided the legal basis for its activities, which defined the representative organizations, the status and term of office, rights and responsibilities of members of the organization and the ministries responsible for its functioning; — The experience of France on this issue can be useful for our country to improve the efficiency of the Commission on Biosafety and Biological Protection under the National Security and Defense Council of Ukraine.

Employing this approach, the author has determined the imperfection of the implementation of the constitutional provisions of this system to identify the causes and nature of the imbalance in the structure of the state mechanism and the functions of its particular elements.

The reason for the separation of the judiciary from the system of checks and balances is underlined in this article. Besides, the author has examined the special place of the judiciary, alongside it’s rise above other state bodies and the factors that have caused the constitutional crisis in Ukraine and the confrontation between the Constitutional Court and other state bodies and civil society.

The peculiarity of the appointment mechanism of judges of the Constitutional Court of Ukraine, the reasons for possible political dependence of judges is examined as well. The European and American constitutional control systems are compared, attention is focused on different legal concepts of understanding the constitutional control, the practice of constitutional justice.

A legal mechanism for overcoming the constitutional crisis and reforming the Constitutional Court of Ukraine is offered in the article.

Proposals are made for the legal improvement of the legal structure of the system of checks and balances based on the transition to the American system of constitutional control.

The effects of the energy crisis and the rising energy demand have sparked development to improve efficiency in using fuel oil. According to Indonesia's oil resources, increasing refinery capacity and building mini refineries is essential to secure local refinery production. It is more effective and cost-effective to construct a small refinery with a configuration starting with a flash unit or pre-fractionator, to an atmospheric distillation unit, and a vacuum distillation unit as the last process in each oil-producing region than construct a large-scale refinery. The optimization concerned a variety of preflash furnace temperatures simulated by Aspen Plus software. The increasing temperature will change the production rate and the utility needed, which could change sales and operating costs. The result describes that the optimum profit for the mini-refinery plant is performed preflash furnace at 533 K with 108.20 US$/m3 crude oil profit.

Authors: Fang Zhong , Lv Siqi , Chiu Yung-ho , Lin Tai-Yu , Lin Yi-Nuo
Published: February 2023

China’s total R&D funding has increased from CNY 89.6 billion in 2000 to CNY 2,442.6 billion in 2020 or by 27 times in 20 years. Although a large amount of literature has analyzed China’s R&D efficiency, scant studies have targeted second-stage economic and environmental efficiencies and rarely considered both university and industrial R&D. This research thus uses the Parallel Two-stage Undesirable Dynamic Model to evaluate the R&D efficiencies of universities and industry and examines their impact on the economy and the environment. The empirical results are as follows. 1) There are differences in the R&D and environmental efficiency of various regions in China with the eastern part being the highest, the western part second, and the central part the lowest. 2) The input index efficiency of universities is generally higher than that of industry. 3) The linkage effect between universities and the local economy and the environment is higher than that of industry.
Independência da massa e modelagem newtoniana para a translação de objetos acelerados em cenários de investigação aberta
Authors: Silva Erick Dos Santos , Araujo Alexandre Alberto Visentin Ramos de
Published: February 2023

A análise de objetos que descem rampas apoiados sobre rodas frequentemente é realizada por meio de uma associação com modelos que descrevem objetos deslizantes, o que pode causar confusões para estudantes que iniciam suas investigações em física. A mesma dificuldade costuma ocorrer quando se tenta justificar que a aceleração de um objeto deslizante ao longo de uma rampa, sem atrito, não é influenciada por sua massa. Esses problemas podem ser minimizados quando consideramos um cenário de modelagem aberta, onde hipóteses estruturantes podem ser consideradas e avaliadas por meio de um processo de validação experimental. O que seria deslizar sem atrito? Em que medida podemos aproximar o movimento de translação de um objeto que desliza em contato macroscópico com uma rampa de outro que tem contato realizado por meio de rodas? No presente trabalho, apresentamos um experimento que utiliza as técnicas de videoanálise para investigar precisamente essas questões, podendo ser implementado nos espaços escolares usuais, sem necessidade de grandes intervenções. A proposta pode ser utilizada para aproximar estudantes de investigações técnicas e modelagens em perspectiva aberta, em diálogo com as demandas científicas e tecnológicas atuais.
Development of a Model Rocket Trajectory Simulation Tool with Python
Authors: Júnior Domingos Sávio Pinheiro do Nascimento , Gurgel Jasson Fernandez , Reis Marcello , Wehmann Claus Franz
Published: February 2023

Within any space mission, the design of the trajectory that the spacecraft will travel across is one of the essential and most important steps. For the launch of smaller rockets, this is also a key analysis to be done during the development of the project, ensuring that the rocket achieves its flight objectives and enabling the definition of a safety radius based on its landing site. Therefore, the present work proposes the development of a tool to simulate the trajectory of small rockets that is satisfactory for use in academic projects, acting as a free alternative to similar software available on the market. For this task, the Python programming language is used, due to its open-source characteristic and shorter execution times compared to similar languages during the execution of numerical computation methods, which are necessary for modeling the rocket's flight dynamics. The results found with the use of the tool for simulating the trajectory of a model rocket are sufficient for the purpose of this work, reaching similar findings to those of simulations carried out in OpenRocket (a JAVA rocket trajectory simulation software, widely used in academic space). Moreover, a Monte Carlo simulation is performed, in which an impact point dispersion radius is estimated.

Quelle gestion de la performance en matière de développement économique local ? Le cas d’une métropole française
Authors: Brakrim Hamza , Huron David
Published: February 2023

Les études sur la Gestion de la Performance (GP) publique concernent majoritairement des pays anglo-saxons ou nordiques. Plus précisément, la recherche sur la GP dans les collectivités locales s’est concentrée sur des compétences où les mesures de performance sont plus faciles à élaborer, tandis que peu d’attention a été accordée à la GP en matière de développement économique local. Les quelques études qui se concentrent sur la GP dans les collectivités françaises n’ont pas abordé le contexte de la métropole. Dès lors, cette recherche a pour ambition de réduire le décalage de mise en œuvre de la GP existant entre la France et les pays anglo-saxons, et de combler ces manquements par une recherche exploratoire fondée sur une étude qualitative d’un cas unique dans l’une des plus grandes métropoles françaises. Nous ambitionnons, d’une part, d’examiner le processus de conception et de mise en œuvre d’un Système de Gestion de la Performance (SGP) en matière de développement économique, d’autre part d’identifier les différents types d’utilisation de ce système. L’exploration de la littérature sur les SGP, nous a permis d’aboutir à l’élaboration un cadre d’analyse fondé sur les modèles de Otley (1999) de Botton et al. (2012) et de Padovani et Scorsone (2009). Les résultats montrent, en premier lieu, que les pratiques de mesure de la performance et l’évaluation ponctuelle représentent deux approches complémentaires pour la gestion de la performance de l’action économique. En second lieu, ces résultats soulignent que le SGP est utilisé à des fins internes, pour le suivi et l’analyse des résultats, l’apprentissage, la prise de décision stratégique, la gestion des contrats et des partenariats, le pilotage global lors des dialogues de gestion unifiés, et pour la reddition des comptes aux élus.
The Use of Nursing Theory to Support Sexual and Reproductive Health Care Education in Nursing Curricula
Authors: Martin Walker Crystal , Anderson Janeane N. , Clark Ricketta , Reed Laura
Published: February 2023

Background:

Inclusive sexual and reproductive health care (SRH) content is limited in nursing curricula, resulting in nurses who lack education to provide complex SRH services to marginalized patients, especially sexual and gender minorities (SGM).

Method:

The 10 Caritas Processes, the framework of Watson's Theory of Caring, were evaluated for being integral components of SRH. This theory is used to advocate for SGM-inclusive SRH content in nursing curricula.

Results:

The interpretation of Caritas Processes 2, 4, and 7 provide theoretical support for SGM-inclusive SRH content. Specific strategies to modify and improve nursing curricula are described.

Conclusion:

There is a need to incorporate inclusive SRH education into nursing curricula to normalize evidence-based SRH for diverse, marginalized patient populations. By emphasizing the caring intentions necessary for nursing professionals, Watson's Theory of Caring is an appropriate framework to guide the development of SGM-relevant SRH content in nursing education.

Differential Grading of Reflective Writing Between Clinical Instructors and Faculty Type
Authors: Novotny Nancy L.
Published: February 2023

Background:

It is important for instructors to give equivalent grades for comparable student performances on an assignment. Students complain of differential grading, especially when multiple instructors grade a course assignment.

Method:

This descriptive comparative study examined clinical instructor-assigned grades for reflective thinking and writing components. Grades for 480 critical reflective papers by 80 undergraduate nursing students were assessed for differences between clinical group instructors and part-time versus full-time instructors.

Results:

Despite evidence of comparable student performance on the assignment across both groups, grades differed among the 10 instructors on both components. Grades differed between part-time and full-time faculty on reflective thinking but not writing, with part-time faculty grading reflective thinking higher than full-time faculty.

Conclusion:

Differential grading was identified between clinical instructors and type of faculty. The merit of multiple instructors grading a single course assignment warrants reconsideration. Enhanced grading training is recommended for part-time instructors who are expected to grade written assignments.

Mental Health Characteristics of Traditional and Accelerated Baccalaureate Prelicensure Nursing Students
Authors: Owen Melissa I. , Pfeiffer Katherine M.
Published: February 2023

Background:

Mental health issues in college students are increasing, and nursing students may experience higher stress and anxiety levels than other college students. Limited data differentiate mental health characteristics of traditional Bachelor of Science in Nursing (BSN) and accelerated Bachelor of Science in Nursing (ABSN) students.

Method:

This descriptive mixed-methods study compared mental health characteristics between BSN (
n
= 21) and ABSN (
n
= 51) students.

Results:

Mild to moderate distress was identified with the Psychological Distress Profile, and moderate levels of stress were identified on the Perceived Stress Scale. No significant differences in scores were found between groups. More ABSN students reported mental health diagnoses than BSN students. Common reasons for stress included academic obligations, relationship challenges, and financial concerns.

Conclusion:

Nursing students report experiencing psychological stress, although reasons may vary by cohorts. Further investigation and development of support programs for student mental health is warranted.

Remember to Leverage Effect Size Estimates
Authors: Taylor John M.
Published: February 2023

In 2023, the Methodology Corner column has opted to promote the efficacious use of effect sizes among our community of researchers. In this first entry of the year, we call attention to broad improvement in effect size reporting germane to our community, including more consistent reporting of effect sizes and their interpretations.

Spherical Aberration of Cataractous Eyes and Its Relationship With Age, Ocular Biometry, and Various IOL Platforms
Authors: Hirabayashi Matthew T. , Gharabagi Areiss P. , Hesemann Nathan P. , Johnson Sandra M. , Webel Aaron D. , Petroski Gregory F. , Davis Geetha R.
Published: February 2023

Purpose:

To determine the median spherical aberration (SA) of the cataractous population, how it relates to biometry, and the theoretical effect of different intraocular lens (IOL) platforms.

Methods:

A retrospective chart review of patients undergoing cataract surgery evaluation with a high quality Pentacam (Oculus Optikgeräte GmbH) were included. Age, gender, Q-value, mean total SA, higher order aberration root mean square wavefront error, and equivalent keratometry were collected from the Holladay report and axial length and anterior chamber depth (ACD) from the IOLMaster 700 (Carl Zeiss Meditec AG).

Results:

Data from 1,725 eyes of 999 patients were collected. SA had a median of 0.37 µm (95% confidence interval: 0.36 to 0.38. Age (
r
= .136,
P
< .001), Q-factor (
r
= .743,
P
< .001), and higher order aberration root mean square wavefront error (
r
= .307,
P
< .001) were positively correlated with SA. Average equivalent keratometry (
r
= −.310,
P
< .001) was negatively correlated with SA. Axial length (
r
= −0.037,
P
= .120) and ACD (
r
= .004,
P
= .856) had no association with SA. Up to 1,499 (86.9%) theoretically had SA moved closer to zero with IOLs that had negative SA. Up to 102 (5.9%) had SA theoretically worsened.

Conclusions:

SA is not normally distributed, suggesting that there may be no “average” SA that IOLs should aim to correct. Patients might benefit from tailoring IOL choice to individual SA. Without access to SA data, eyes with steeper average keratometry or younger patients may have less SA, which could influence IOL choice.

Metabolic Consequences of Pediatric Obesity: A Review of Pathophysiology, Screening, and Treatment
Authors: Gunaratne Naiomi , Deplewski Dianne
Published: February 2023

The prevalence of pediatric obesity has been increasing during the last 30 years, and the subsequent metabolic consequences of obesity, which were mainly seen in adults, are now presenting in childhood. Type 2 diabetes, prediabetes, metabolic syndrome, and nonalcoholic fatty liver disease are serious metabolic ramifications of pediatric obesity; pediatricians need to be familiar in screening and treatment of these metabolic issues. This review will discuss the inflammation and insulin resistance involved in obesity that can lead to these conditions. We will explore the pathophysiology of type 2 diabetes and prediabetes, metabolic syndrome, and nonalcoholic fatty liver disease and review screening and treatment modalities. Finally, we will highlight other important endocrine related comorbidities in pediatric obesity, including polycystic ovary syndrome, precocious puberty, and early accelerated growth.
