Veri Madenciliği ve Hemşirelik
Authors: Özel Filiz
Published: October 2023

Günümüzde dijital ortamda verilerin artmasıyla birlikte veri madenciliği ortaya çıkmıştır. Veri madenciliği yönteminde toplanan veriler temizlenip, işlenerek analiz edilir. Veri madenciliği algoritmaları tanımlayıcı ve tahmine dayalı olmak üzere ikiye ayrılmaktadır. Veri madenciliği yöntemlerini gerçekleştirmek için ticari ya da açık kaynak kodlu yazılımlar şeklinde birçok yazılım kullanılmaktadır. Veri madenciliği birçok verinin toplandığı çoğu alanda olduğu gibi sağlık alanında da kullanılabilmektedir. Literatür incelendiğinde yeni bir disiplin olan veri madenciliğine ilişkin hemşirelik alanında araştırmalarının ülkemizde yetersiz olduğu görülmüştür. Özellikle hemşirelik bakım planlarına yönelik çevrimiçi veri toplanması, saklanması ve işlenmesinde sorunlar yaşandığı görülmüştür. Tüm bunlardan yola çıkılarak, bu derlemede veri madenciliği, sağlık ve hemşireliğe yönelik araştırmalar üzerinde durulmuştur.
Convergent Synthesis of a Hexadecavalent Heterobifunctional ABO Blood Group Glycoconjugate
Authors: Daskhan Gour Chand , Tran Hanh-Thuc Ton , Cairo Christopher W
Published: October 2023

Naturally occurring glycans are often found in a multivalent presentation. Cell surface receptors that recognize these displays may form clusters, which can lead to signalling or endocytosis. One of the challenges in generating synthetic displays of multivalent carbohydrates is providing high valency as well as access to heterofunctional conjugates to allow attachment of multiple antigens or payloads. We designed a strategy based on a set of bifunctional linkers to generate a heterobifunctional multivalent display of two carbohydrate antigens to bind BCR and CD22 with four and twelve antigen copies, respectively. We confirmed that the conjugates were able to engage both CD22 and BCR on cells by observing receptor clustering. The strategy is modular and would allow for alternative carbohydrate antigens to be attached bearing amine and alkyne groups and should be of interest for the development of immunomodulators and vaccines.
A Simple Electron-Density Based Force Field Model for High-Energy Interactions between Atoms and Molecules
Authors: Romero José , Limão-Vieira Paulo , Hermansson Kersti , Probst Michael
Published: October 2023

In high-energy molecular dynamics or Monte-Carlo simulations, standard force fields that are optimised for simulations at ambient temperature are inadequate. This is largely because their repulsive part has been regarded as not very significant even well below zero interaction energy. It is therefore not obvious which force fields to resort to for simulating hot gases or plasmas. A Force Field model which uses the electronic densities of non-interacting atoms or molecules within the pair approximation is introduced. We start by deriving a naïve model that neglects any exchange and correlation effects between the electronic clouds and then correct this model by adding a term calibrated from ab initio calculations using CCSD(T)/cc-pVTZ level of theory. The resulting expression can be regarded as a simple exchange-correlation functional. We compare the results for the repulsive part of the potential energy hyper-surfaces with force fields commonly used on some dimers of small molecules.
Nuclear Quantum Effects in Gas-Phase 2-Fluoroethanol
Authors: Arandhara Mrinal , Ramesh Sai G.
Published: October 2023

Torsional motions along the FCCO and HOCC dihedrals lead to the five unique conformations of 2-fluoroethanol, of which the gauche conformer along both dihedrals has the lowest energy. In this work, we explore how nuclear quantum effects (NQEs) are manifest in the structural parameters of the lowest energy conformer, in the intramolecular free energy landscape along the FCCO and HOCC dihedrals, and also in the infrared spectrum of the title molecule, through the use of path integral simulations. We have first developed a full dimensional potential energy surface using the reaction surface Hamiltonian framework. On this potential, we have carried out path integral molecular dynamics simulations at several temperatures starting from the minimum energy well to explore structural influences of NQEs including geometrical markers of the interaction between the OH and F groups. From the computed free energy landscapes, significant reduction of the torsional barrier is found at low temperature near the cis region of the dihedrals, which can be understood through the trends in the radii of gyration of the atomic ring polymers. We find that the inclusion of NQEs in the computation of infrared spectrum is important to obtain good agreement with the experimental band positions.
The effect of patients' e-health literacy on their preoperative anxiety levels and fears about anesthesia
Authors: SALTALI Ali Özgül
Published: October 2023

The aim of this study is to examine the effect of e-health literacy on preoperative anxiety levels and fears about anesthesia of individuals who will undergo surgery. The research was carried out with 219 patients waiting in the preoperative waiting unit. The Amsterdam Preoperative Anxiety Scale (APAIS) was used to evaluate the preoperative anesthesia anxiety, the E-Health Literacy Scale was used to determine the e-health literacy, and the questionnaire form was used to determine the fear of anesthesia, which was created by using the items in the literature in previous studies on anesthesia fear. According to the results of the research, the three items that patients fear the most about anesthesia are; “feeling pain during surgery”, “feeling pain after the effect of post-operative anesthesia” and “waking up in the middle of surgery”. There is no significant difference in anesthesia-related fears of patients with low, medium and high e-health literacy, only a significant difference in preoperative anxiety scores between patients with low and high e-health literacy. Study results were interpreted as the ability of individuals with high e-health literacy to evaluate the data obtained through digital channels in terms of reliability prevents them from experiencing unnecessary anxiety based on erroneous information.

Published: October 2023

La industria de la energía solar fotovoltaica (PV, por sus siglas en inglés) ha experimentado un rápido crecimiento en los últimos años. A pesar de los avances en su desarrollo, queda mucho trabajo por hacer en el área de acondicionamiento y conexión de sistemas PV a la red. Se debe estudiar el comportamiento de los sistemas PV bajo diferentes condiciones, así como el desarrollo de nuevas estrategias de control para mejorar la operación y protección. Hardware-in-the-loop (HIL) es una técnica de simulación en tiempo real que permite conectar dispositivos y modelos de hardware y software a través de una interfaz digital. Permite una imitación muy cercana de los sistemas del mundo real a través de la emulación de su funcionamiento. La técnica HIL ha cobrado protagonismo en los últimos años para el estudio y desarrollo de sistemas de control, monitorización y protección de infraestructuras, pues permite probar múltiples escenarios sin el costo de requerir implementaciones físicas de todo el sistema en evaluación. Para abordar los puntos anteriores, este trabajo presenta el diseño de un simulador de sistemas PV con conexión a la red empleando la técnica HIL. Este simulador permite implementar y estudiar escenarios operativos, evaluando esquemas de control con fines prácticos, experimentales e investigativos para apoyar la formación de estudiantes de pregrado y posgrado del área de ingeniería eléctrica e ingeniería electrónica de la Universidad Industrial de Santander (UIS). Este trabajo se realiza en el marco del proyecto de investigación titulado "Estrategia pedagógica para el fortalecimiento de competencias en STEM mediante sistemas modulares de laboratorio", código 2825, financiado por la Vicerrectoría de Investigación y Extensión de la UIS y el proyecto de investigación financiado por Minciencias titulado “Diseño de estrategias alternativas de operación y control para sistemas fotovoltaicos multifuncionales en redes de distribución con alta penetración de energías renovables” código 70416, desarrollado en el marco del “Programa de Investigación en Tecnologías Emergentes para Microrredes Eléctricas Inteligentes con Alta Penetración de Energías Renovables” contrato 80740-542-2020.

Published: October 2023

Uno de los requerimientos operativos que los códigos de red imponen a los generadores distribuidos conectados a las redes de distribución es la capacidad de operar ante hundimientos de tensión (LVRT, por sus siglas en inglés). Esta capacidad, en conjunto con otras funcionalidades como las acciones de regulación de tensión y frecuencia, y la compensación de carga, son fundamentales para garantizar la estabilidad, confiabilidad y calidad de la energía en las redes eléctricas. Para la incorporación de este tipo de capacidades y funcionalidades en la operación de generadores distribuidos interconectados a la red mediante inversores de potencia, se requieren algoritmos que permitan controlar las potencias activa y reactiva que se inyectan a la red según los objetivos a cumplir. Para abordar lo anterior y dado el alto interés en el uso de topologías de convertidores modulares multinivel (MMC, por sus siglas en inglés) en estas aplicaciones, este trabajo aborda el análisis del desempeño de tres topologías de inversores de conexión a la red: dos de ellas correspondientes a inversores modulares multinivel (topologías MMC con salida de punto medio y MMC con punto neutro), y la otra al inversor tradicional trifásico en puente completo. El trabajo presenta un análisis comparativo del desempeño de las tres topologías ante diferentes escenarios de inyección de potencia activa y reactiva a la red. Asimismo, se presenta una descripción de las estrategias de: control de potencia, seguimiento de la señal de referencia y modulación por ancho de pulso. Se utiliza como herramienta de simulación el software PLECS, donde se implementa cada topología y se obtienen los resultados para analizar algunos parámetros comparativos preestablecidos. Este documento presenta los resultados del trabajo final de pregrado en Ingeniería Eléctrica de la Universidad Industrial de Santander (UIS) titulado “Control de potencia activa y reactiva en inversores modulares multinivel de conexión a la red” vinculado al proyecto de investigación financiado por Minciencias titulado “Diseño de estrategias alternativas de operación y control para sistemas fotovoltaicos multifuncionales en redes de distribución con alta penetración de energías renovables” código 70416, desarrollado en el marco del “Programa de Investigación en Tecnologías Emergentes para Microrredes Eléctricas Inteligentes con Alta Penetración de Energías Renovables” contrato 80740-542-2020.

Published: October 2023

The Muara Laboh geothermal field lies in a South Solok basin zone, West Sumatra, Indonesia. Production and reinjection of geothermal fluids into the underground reservoir commonly induce crustal deformation. The study area is covered by 63.8% plantation, primary, and secondary forests, which limit the ability of conventional InSAR techniques. Therefore, an Intermittent Small BASeline Subset (ISBAS) analysis has been performed to estimate line-of sight (LOS) displacement time series due to geothermal production using the Sentinel-1 dataset between 8 March 2021 and 15 March 2022. The localized subsidence with ∼30 mm/yr rate over this tropical geothermal field has been revealed by using the ISBAS. The subsidence coincides with an area of the Muara Laboh geothermal reservoir. We suggest that geothermal production induced subsidence. In addition, the deformation in this geothermal field was controlled by faults and seasonally influenced by rainfall. Therefore, deformation variation was correlated with fluctuations in rainfall patterns. The geothermal reservoir system exhibited elastic expansion in response to seasonal recharge events during the rainy season.

Published: October 2023

In a weighted connected graph, the shortest total path length spanning tree problem is a problem when we need to discover the spanning tree with the lowest total cost of all pairwise distances between its vertices. This problem is also known as the minimum routing cost spanning tree (MRCST). In this study, we will discuss the Modified Sollin and Modified Dijkstra Algorithms to solve that problem which implemented on 300 problems are complete graphs of orders 10 to 100 in increments of 10, where every order consists of 30 problems. The results show that the performance of the Modified Dijkstra and the Modified Sollin Algorithms are slightly similar. On orders 10, 20, 30, 60, and 80, the Modified Dijkstra Algorithm performs better than the Modified Sollin, however on orders 40, 50, 70, 90, and 100, the Modified Sollin performs better.

Authors: Arundale Amelia J.H. , McNulty Roisin , Snyder Cory , O'Brien James , Stöggl Thomas
Published: October 2023

Background

Breakdancing or breaking will enter the Olympics in 2024, however, there is a paucity of literature exploring the epidemiology, demands, and performance.

Purpose

The purpose of this study was to describe injury and training profiles, along with the results of a short performance test battery, in a group of elite breakers.

Study Design

Cross-sectional study (retrospective).

Methods

Fourteen breakdancers (breakers) (4 Bgirls, 10 Bboys) participated in an interview regarding their injury and training history, endurance test (cycle VO2max testing), counter movement jump, squat jump, drop jump, isometric hip abduction, adduction, shoulder external and internal rotation strength testing on a fixed-frame dynamometer. Breakers were divided into elite (n=10) and developing (n=4) based on their qualification for a world finals competition; Wilcoxen rank sums were used to compare the two groups, or in the case of strength testing between those with and without an injury history.

Results

The breakers had a median 11.0 [10.0 - 14.0] years breaking experience and trained 24.4 [20.5 - 30.0] hours per week. The knee was the most commonly injured body part and most frequently injured joint, with the thigh being the most common site for muscle injuries. There were no differences in endurance testing or jump height testing results between elite and developing breakers. There was no difference in shoulder external or internal rotation strength between athletes with a history of shoulder injury and those without. Similarly, there was no difference in hip abduction or adduction strength in those with a history of hip injury and those without.

Conclusion

The results of this study should be viewed with caution due to the small sample size. However, this study is the first to publish functional and physiological descriptives on breakers. The authors hope these results support clinicians treating breakers as well as encourages future research related to breaking.

Perceptions of Physical Therapy and The Role of Physical Therapists  In Injury Prevention Among Professional Basketball Players: A Qualitative Study
Authors: Marks Alison , Courtney Carol A. , Healey William E.
Published: October 2023

Background

Injury prevention is critical in competitive professional sports, however, the role of physical therapists in this aspect of healthcare is not fully understood.

Purpose

The purpose of this study was to describe professional basketball players’ perceptions of physical therapy (PT) and physical therapists’ role in injury prevention.

Study Design

Qualitative, semi-structured interview

Methods

Thirty-five professional basketball players (mean age 23.1 years ± 3.9; 42% female; 72% African American; 90% college graduates) from over 20 teams participated. Athletes participated in semi-structured interviews that focused on injury prevention and utilization of PT services. Two researchers coded the transcripts, organized the findings into general categories, and created major themes. Data saturation was reached when no new information emerged.

Results

Over half (62.9%) stated that PT mainly addressed post-injury and return-to-sport rehabilitation. An overwhelming majority of players highlighted the use of an athletic trainer (AT) over physical therapists in injury prevention due to perceived expertise and trust.

Conclusion

While PTs are educated in preventive care and acute injury management, professional basketball players viewed their role primarily for return-to-sport rehabilitation. The organizational structure of healthcare in professional basketball may promote closer professional relationships with ATs while limiting those with physical therapists. The result is that elite athletes may miss out on treatment specific to the PT profession.

Ligament Healing After Anterior Cruciate Ligament Rupture: An Important New Patient Pathway?
Authors: Forelli Florian , Riera Jérôme , Mazeas Jean , Coulondre Claire , Putnis Sven , Neri Thomas , Rambaud Alexandre
Published: October 2023

Recent studies have shown satisfactory functional results after spontaneous healing of a ruptured anterior cruciate ligament (ACL). However, current literature on this topic may exclude important parting selection, outcome measures, and long-term results. Rehabilitation protocols applied in those studies, as well as objective assessments appear far from the usual gold standard after ACL reconstruction. Ideally, outcomes measures should be based on the same testing procedures that are recommended to clear an athlete to return to sport following ACL reconstruction. There is still a lot to understand in how an injured ACL may heal, and therefore ACL injury management should be individualized to each patient and carefully discussed.
Ibogaine as a Treatment For Alcohol Use Disorder: a Preclinical Investigation
Authors:   , Falkenhaug Sarah
Published: October 2023

Substance use disorders are a debilitating psychiatric condition which contribute to significant personal, legal and economic problems worldwide. Current treatment options, such as pharmaceutical interventions or behavioural therapy, are not always utilised or effective at reducing symptoms. Ibogaine, a psychedelic compound deriving from root bark of the Tabernanthe iboga plant, has shown potential efficacy in treating symptoms associated with a range of substance use disorders. Ibogaine has also been associated with a range of cardiotoxic side effects and fatalities. Further investigation is necessary to understand both the therapeutic efficacy and side effects associated with ibogaine at different doses. The aim of this thesis is to determine whether a single administration of ibogaine reduces ethanol drinking behaviours, and whether it is associated with any significant cardiovascular side effects, in Sprague Dawley rats.

The Intermittent Two Bottle Access Paradigm (I2BAC) was used to induce ethanol drinking behaviour in the animals over an eight week period. Animals were then administered one of two active doses of ibogaine (20 or 40mg/kg), or saline. Ethanol drinking continued for another five days to investigate any long-term changes. Ibogaine’s side effects were investigated in a separate experiment whereby the rats were surgically implanted with Telemetry devices designed to record the ECG. Recordings occurred at baseline, during saline administration, during ibogaine administration (20 or 40mg/kg), 24 hours post- treatment, 48 hours post-treatment, and 1 week post-treatment. Particular parameters of interest were heart rate and QT interval.

Results of the ethanol drinking experiment provide some evidence of a weak dose- dependent effect of ibogaine on ethanol drinking during its’ acute effects, but do not indicate any significant reductions in ethanol drinking long-term. Results of the side effect experiment indicate a significant effect of ibogaine on both QT interval and heart rate during its acute effects. In light of these results, this thesis also discusses new directions and critical methodological factors for future investigations to consider.

Students’ Argumentation through Mathematical Literacy Problems Based on Mathematical Abilities
Authors: Trymelynda Yaffi Tiara , Ekawati Rooselyna
Published: October 2023

Argumentation is an essential mathematical skill employed in mathematical literacy. Argumentation is an individual's ability to think critically to provide reasons based on facts to make conclusions that solve problems. A qualitative approach is used in this study to describe students' argumentation in solving mathematical literacy problems based on mathematics ability level. The research subjects were three twelfth-grade students: one with high mathematics ability, one with moderate mathematics ability, and one with low mathematics ability, which was selected purposively. Data are collected through mathematical literacy problem tests and interviews. The data are analyzed using McNeill and Krajcik's argumentation components: claim, evidence, reasoning, and rebuttal in solving mathematical literacy problems. The results showed that students with high mathematical abilities could formulate and perform the procedures at the evidence indicator; connect information for reasoning indicators; provide general solutions, represent and assess the mathematical solutions at the rebuttal indicators; and make a correct claim. Students with moderate mathematical ability could apply mathematical concepts although made a miscalculation at the evidence indicator; connect information for reasoning indicators; provide partially correct solutions; represent and evaluate the sufficiency of the mathematics solutions at the rebuttal indicator; and make a correct claim. Meanwhile, students with low mathematical ability miss a crucial concept and make miscalculations at the evidence indicator; connect information for reasoning indicators; provide and represent partially correct solutions but cannot evaluate the sufficiency of the mathematics solutions at the rebuttal indicator; provide a correct claim.

Keywords: Argumentation, McNeill Argumentation, Mathematical Literacy Problems, Mathematical Abilities.

Published: October 2023

An instrument was validated through factorial structure to measure the advantages, levels of reflection, and communicative competencies of the podcast, as well as to establish the levels of reliability and consistency of the measuring instrument. Likewise, confirmatory analysis was carried out to validate the proposed structural model and establish the relationships of the factors using the PLS-SEM methodology, Partial Least Squares Structural Equation Modeling. It was validated with a sample of 142 teachers. It was demonstrated that there is a causality relationship of the variables, given by the coefficient of determination R2, the level of influence of the independent variables: levels of reflection and advantages; on the dependent variable, communicative competencies; the level of influence of the exogenous variable: advantages with the endogenous variable: levels of reflection in teachers. A high degree of construct validity was shown through the fit indices of the confirmatory factorial analysis.
The Impact of Self-Esteem on Teacher Leadership: An Experimental Design
Authors: Bolat Özgür
Published: October 2023

This study aims to examine the impact of self-esteem on teacher leadership beliefs in Türkiye through both correlational and experimental analyses since self-esteem is considered to be a crucial antecedent of leadership. The author conducts three separate studies with a sample size of 808. The first study (n = 237) uses correlational analyses (Spearman). The second study (n = 222) adopts a scenario-based, within-participants experimental design where the self-esteem level of teachers is manipulated. A paired t-test was used to analyze the data. The third study (n=349) employs a between-participants experimental design. ANOVA test was conducted to analyze the data. The correlational analysis of the first study found a positive relationship between self-esteem and teacher leadership (rho =.35, p < .001). The second study revealed that participants perceived teachers with high self-esteem to be more likely to exercise leadership, t(221) = 1.97, p < 0.01. The third study found that teachers who were primed to have high self-esteem were more likely to adopt leadership beliefs, F(2, 348) = 3.91, p = .02. The result experimentally demonstrated that self-esteem is an important antecedent of teacher leadership. This study contributes to the literature on teacher leadership by providing a causal link between self-esteem and teacher leadership.

Published: October 2023

In recent years, there has been a growing interest in spatial reasoning as a component of mathematics education, with many countries incorporating it into their mathematics curriculum. The study of spatial reasoning in the learning areas of geometry presents an essential opportunity for improvement of students within the realm of mathematics education. The purpose of this survey research is to examine middle school students spatial reasoning skills. A study was conducted to analyze the spatial reasoning skills of 947 middle school students. The Spatial Reasoning Test was utilized to assess the sub-components of spatial visualization, spatial orientation, and mental rotation. Based on the results, there was no significant difference between male and female students in relation to their overall test scores. However, a statistically significant difference was observed when analyzing the scores of the sub-components and grade levels. Anticipated outcomes of the investigation are expected to provide support and guidance for the preparation of educational tasks and instruction aimed at enhancing students’ spatial reasoning abilities.
Yapılandırmacı Yaklaşım ve Mobil Uygulamalarla Fransızca Öğretimi/Öğrenimi

Published: October 2023

İnsanoğlu, 21. yüzyılda nüfusun çok hızlı arttığı, kıtalar arası göçlerin yaygınlaştığı, dünyanın küreselleştiği ve teknolojinin baş döndürücü bir biçimde ilerlediği bir dönemden geçmektedir. Küresel ölçekte yaşanmakta olan bu köklü değişimler ve gelişmeler bireyleri, toplumları ve eğitim sistemlerinin önemli ölçüde etkilemekte ve biçimlendirmektedir. Bu çalışmada, Genel Tarama Modeline başvurularak öncelikle yabancı dil öğretiminin/öğreniminin teknolojiyle olan ilişkisi (uzaktan eğitim, bilgisayar ve mobil destekli öğrenme), ardından yapılandırmacı yaklaşım ve mobil uygulamaların yabancı dil Fransızca öğretme/öğrenme süreçlerine yaptığı katkılar incelenmiştir. Bu bağlamda Fransızca mobil uygulamaların Avrupa Diller için Ortak Başvuru Metni ölçütlerine uygun olduğu ve en çok bilinenlerinden (Duolingo, Babbel, Mosalingua, vb.) daha az bilinenlerine kadar yapılandırmacı yaklaşımın ilkeleri ile örtüştüğü görülmüştür. Öte yandan alanyazında, insanoğlunun geçmişten günümüze yabancı dil öğretmek/öğrenmek için sayısız uğraş verdiği ve yabancı dilin en iyi doğal ortamında öğrenilebileceği görüşünü benimsediği gözlemlenmiştir. Fakat öğrencileri yabancı dilin doğal ortamına taşımanın zorluğu eğitim bilimcileri yeni arayışlara sevk etmiş, günümüzde sınıftaki öğrenimleri keyifli ve eğlenceli bir biçimde pekiştirmek, bunları kazanıma dönüştürmek ve sonraki bilgilerle ilişkilendirmek için en kolay ve en etkili yolun teknolojiye başvurmak olduğu sonucuna varılmıştır. Çalışmada Fransızca mobil uygulama içeriklerinin birçok yönüyle yapılandırmacı yaklaşım ile örtüştüğü de görülmektedir. Söz gelimi bir okuma etkinliğinde öğrenilen sözcük ya da ifadeyi dijital içerikli etkinliklerde ve bağlamlarda işitmek, görmek ve kullanmak fazlasıyla mümkün olmuştur. Sonuç olarak, teknoloji ve mobil uygulamalar sayesinde yabancı dil Fransızca öğretiminde/öğreniminde yeni perspektiflerin oluşmaya başladığı, sınıfta edinilen bilgilerin güncel yaşamda kolaylıkla kullanılabildiği ve hatırlamaktan çok bilginin yapılandırıldığı bir öğrenme/öğretme anlayışı başlamıştır.
Post-hümanizm ve posthümanizm söylemlerinin yersizyurtsuzlaşma kavramı üzerinden yeniden incelenmesi
Authors: YANAR Muhsin
Published: October 2023

Dört sanayi devrimi boyunca bilim ve teknoloji, insanlığı, kültürleri ve günlük pratikleri değiştirme, geliştirme ve dönüştürme arzusuyla hareket etmiştir. Bir toplum mühendisliği türü olarak nano-, biyo-, bilgi- ve bilişsel teknolojiler gibi modern teknolojiler, yaşam alanları ve bedeni kontrol ederek bu değişim ve dönüşüme katkıda bulunmuştur. Bu teknolojiler toplumu ve bedeni ele geçirme, kontrol ve disipline etme hususlarında gelecekteki olasılıkları keşfetmekle kalmamakla beraber bunların sömürülmesine de katkıda bulunmuştur. Yani, ‘tek boyutlu’ insanlar, teknolojinin egemen olduğu (ilkel) bir ortamda yaşamaya zorlanmış ve çevreleri ve bedenlerinden yersizyurtsuzlaştırılıp yeniden yurtlandırılmışlardır. Post-hümanizm ve post-hümanizmin kapsamı dikkate alındığında, bu diskurlar fiziksel ve kavramsal olarak insana ait yerleşik sınırlar, yapılar ve hiyerarşiler, akışkanlık ve melezlik geliştirmekte; yeni/alternatif sınırlar oluşturmakta; çeşitli kültürlerin, alternatiflerin bol olduğu yeni veya alternatif sistemler oluşturmaktadır. Bu bağlamda, bu makale post-hümanist ve posthümanist diyaloglarda yersizyurtsuzlaşma ve yeniden-yerliyurtlulaşma kavramlarını irdelemektedir. LaGrandeur’un post-hüman/izm ve posthüman/izm tanımlarına dayanan bu makale, post-hümanist ve posthümanist tartışmaların insan/insan olmayanlar kavramını hem yersiz yurtsuzlaştıran hem de yeniden yurtlandıran olarak nasıl görülebileceğini inceleyecektir.
