СТРАТЕГІЯ МАЙБУТНЬОЇ УКРАЇНИ: ТРАЄКТОРІЯ ЕКОНОМІЧНОГО ВІДРОДЖЕННЯ
Authors: Тарасенко А. Б.
Published: April 2024

Жорстокий військовий конфлікт в Україні продовжує залишати по собі безпрецедентну у сучасній Україні кількість зруйнованої інфраструктури, понівечених підприємств та скалічених людських доль, що спричиняє спустошення та втрати, однак дух стійкості є незмінним, що підживлюється рішучістю не просто відновити, а заново уявити, винайти власне майбутнє, яке натхненне економічним зростанням та розвитком на всіх рівнях країни. Цей важкий шлях до національного відродження розгорнеться в мережі викликів, що вимагають багатогранного підходу. Розуміння та розпізнавання ризиків і того, як із ними боротися, - тільки так можна увійти в успішне майбутнє, що й визначає суттєву актуальність дослідження. В аналізі відображено кількісну оцінку вже наявних втрат країни. Зниження ВВП, збільшення інфляції та реального безробіття - не просто показники; це вже установлені передумови важкого шляху до відбудови, який попереду. Розуміння складного переплетення таких явищ матиме вирішальне значення для формування ефективної економічної політики. Запланований обсяг фінансування плану відновлення України у розмірі 750 млрд доларів є дійсно амбітним, але він є необхідним для того, щоб країна могла повноцінно відновитися після війни. План передбачає залучення коштів із різних джерел, включаючи гранти, кредити та приватні інвестиції, репарації. Найбільші суми фінансування будуть спрямовані на відновлення інфраструктури, модернізацію енергетичного сектору та підтримку фінансової системи. Саме вони є пріоритетними напрямами для відновлення України, оскільки складають основу країни. Цей підхід є ефективним, однак його повна реалізація в умовах невизначеності може виявитися далекою від гарантованої. Важливо, аби для відновлення України був складений добре скоординований план «Б», що дозволить забезпечити мінімальні та найбільш важливі потреби країни та населення. Не менш важливою є і пріоритезація інвестицій у людський капітал, що дасть можливість посилити довіру населення та ефективніше боротися з безробіттям. Дотримуючись прозорості, підзвітності та орієнтуючись у складнощах глобального економічного ландшафту, Україна здатна прокласти шлях до стійкішого та дійсно справедливого майбутнього. Підбиваючи підсумок, варто зазначити, що запланований обсяг фінансування плану відновлення України є важливим першим кроком у бік вирішення поставленого питання. Однак існує ряд ризиків, через які значна кількість необхідних ресурсів, імовірно, не зможе бути залучена. Вирішення цих викликів стане найбільш суттєвою задачею. Аналіз інших викликів при більш індивідуальному підході до сфер інвестицій являє собою головний простір для дослідників, які мають продовжувати невтомно працювати над їх вирішенням для забезпечення м’якого входу у майбутнє для України.

Thin film based on gold nanoparticles or AuNPs is typically used as catalyst in the industrial processes due to their high stability and good reusability. In this work, a thin AuNPs-silica composite film was fabricated firstly from sol-gel method by mixing gold pyrazolate complex to a medium comprised of ethanol, deionized water, and hydrochloric acid followed by addition of tetrabutyl orthosilicate as silica source. Next, 70 microliters of the sol-gel solution were spin-coated on several type of substrates such as glass, anodized aluminium oxide or AAO, and combination of both to yield gold complex-silica composite film. It was found that gold complex-silica composite film fabricated on combination of both AAO-glass substrate gave the best quality based on its surface thickness, layer uniformity and film brittleness. Later, the film was selected and subjected to thermal hydrogen reduction at 210 degrees Celsius for 2 hours to facilitate the formation of gold nanoparticles to give AuNPs-silica in AAO-glass film. Before the heat treatment, the light-brownish colour of the original gold complex-silica in AAO-glass film in daylight will appear as a pinkish red film under UV light, suggesting the interaction between gold atoms and supported by its luminescence spectrum at 692 nm. Upon heat treatment, the resulting AuNPs-silica in AAO-glass film gave a deep-red colour indicating the successful formation of AuNPs. The presence of AuNPs in the film was further confirmed based on the absorption peak at 545 nm, X-ray diffraction pattern at 38.20 degrees for d111 plane in wide-angle region, transmission electron microscopy images showing a small and sphere shape particles as well as its elemental composition in energy dispersive X-ray analysis. Moreover, scanning electron microscope images also suggested that the AAO pores is fully filled with the composite and is in accordance with its surface roughness study via atomic force microscopy analysis.

Приближенно решена задача об осесимметричном деформировании тонкой цилиндрической оболочки под действием локального температурного поля, действующего по кольцевой части ее боковой поверхности. Решение базируется на использовании классической теории оболочек и применении аппарата обобщенных функций. В связи с последним точное решение задачи невозможно и используется решение методом Бубнова в высоких приближениях. Рассмотрен также и вариант исследования обратной задачи, когда по известным перемещениям оболочки можно установить допускаемые температурные режимы ее термообработки. Приведены примеры. Результаты работы могут быть использованы при прогнозировании напряженно-деформированного состояния тонкостенных конструкций в условиях нестационарного аэродинамического нагрева их отдельных участков, вызванного как конвективным теплопереносом, так и теплотой химических реакций (окисление, катализ).

Приведены результаты расчетно-экспериментальных исследований по влиянию энергии удара на остаточную прочность силовых панелей крыла. Объектом исследований являлись двухстрингерные панели силового кессона крыла из ПКМ с повреждениями обшивки, полученными при различных энергиях удара. В процессе испытаний оценивалась остаточная прочность панелей при осевом сжатии и напряженно-деформированное состояние зоны ударного повреждения с помощью тензометрии. Полученные результаты позволили определить зависимость остаточной прочности панели от энергии нанесенного удара. Показано, что существует пороговое значение энергии удара, после которого имеет место резкое снижение остаточной прочности панели в относительно узком диапазоне изменения энергии удара. Дальнейшее увеличение энергии не оказывает значительного влияния на остаточную прочность панели. Результаты экспериментальных исследований дали возможность сопоставить критические напряжения локальной потери устойчивости зоны повреждения со степенью повреждения матрицы композиционного пакета при разных уровнях энергии удара. Полученные данные дают потенциальную возможность моделировать ударные повреждения композита в крупных силовых агрегатах конструкции планера летательного аппарата, не прибегая к сложным и трудоемким математическим моделям. В целом, результаты выполненных экспериментальных работ подтвердили предположение, что механизм разрушения композита при наличии ударного повреждения связан с его локальной потерей устойчивости вследствие снижения характеристик жесткости поперечного сдвига пакета.
Leonard Cohen, la formación en ciencias de la salud y la dicotomía básica – clínica, un problema perpetuo a resolver en los nuevos currículos universitarios basados en evidencia

En 2016 la asignación del premio Nobel de literatura a un cantautor norteamericano, Bob Dylan, generó gran consternación en el medio literario. Muchos lo vieron como una falta de respeto a la tradición literaria, una herejía. Sin embargo, una decisión similar, pionera y revolucionaria la había tomado cinco años antes la Fundación Príncipe de Asturias cuando concedió el premio Príncipe de Asturias de las letras 2011 a un músico y poeta de habla no hispana: el canadiense Leonard Cohen. Tanto Cohen como Dylan más que artistas fueron pensadores con visión reflexiva uno y crítica el otro, que expusieron y denunciaron los grandes problemas sociales del siglo XX: violencia, desigualdad, discriminación, pobreza, inequidad, falta de oportunidades, desconfianza en las instituciones, soledad, angustia, desesperanza. Tal vez el premio a Cohen fue más relevante, pero menos mediático y lo tomamos de referencia para el editorial de este número.
El ciclo progresivo: un giro a la izquierda en la política latinoamericana
Authors: Veltmeyer Henry
Published: April 2024

Este artículo explora la dinámica política asociada con lo que se ha descrito como una ‘marea color de rosa’ de cambios de régimen en América del Sur y un ‘ciclo progresista’ en la política latinoamericana: regímenes preocupados por profundizar el neoliberalismo en la búsqueda de un desarrollo más inclusivo. Este ciclo progresista, que no coincidió por casualidad con el auge de las materias primas en los mercados capitalistas, se desarrolló en América del Sur: en Venezuela, Brasil y países cercanos a los Andes (Argentina, Bolivia, Ecuador). El ensayo también destaca las limitaciones del nuevo desarrollismo, que consiste en el modelo económico neoextractivista utilizado por los gobiernos del Marea Rosada para avanzar en su agenda política. Este modelo atrapa a la economía política en las contradicciones del sistema capitalista.
Ecuador: el proceso histórico hacia una economía social en confrontación con el modelo empresarial-neoliberal
Authors: Paz y Miño Cepeda Juan
Published: April 2024

En este artículo realizo una propuesta de interpretación y análisis histórico sobre la trayectoria del Ecuador en el siglo XX, enmarcándola en las condiciones latinoamericanas que sean correspondientes para fundamentar la explicación. Resalto varios momentos históricos de ese proceso, desde la perspectiva de las políticas económicas que se siguieron y, además, destaco sus características esenciales. Enfoco el tema para arribar a la historia inmediata, a fin de comprender al progresismo ecuatoriano de nuestros días y su abierta confrontación con el modelo de economía empresarial-neoliberal. Expongo el tema como una síntesis y guía, que permita orientar las investigaciones sobre América Latina y Ecuador. No debe considerarse como un esquema cronológico y necesariamente igual en todos los países, pero sí como una forma de abordar la interpretación del presente a partir de una serie de procesos de tipo histórico desde el pasado.

Field study was carried out at Umuowa Ibu1 via National Horticultural Research Mbato Okigwe Imo state, Nigeria, to evaluate the effect of cropping systems on growth and yield of castor southeastern Nigeria. The experiment was laid in a randomized complete block design. The treatments were nine castor based cropping systems. Data collected were subjected to analysis of variance. Significant means were compared with LSD at 5% probability level. Result showed that castor seed yield was influenced by cropping systems. Significant castor yield was recorded in the treatment of sole castor with 1289.34 and 1286.77 kg/ha in both cropping seasons, followed by 1288.43 and 1280.44 kg/ha recorded in castor + cowpea intercrop. The yield obtain from sole castor was not significant difference when compared to yield obtained from castor + cowpea and also in the treatment of castor + groundnut intercrop. The least castor seed yield; 1002.23 and 1007.23 kg/ha was recorded in castor + groundnut + garden egg intercrop. The yield of component crops decreases as number of crops in the systems progressed from two to three.  Castor + cowpea + pepper cropping system had the highest land equivalent ratio (LER); 5.62 and 5.63 in both cropping seasons. The least LER: 2.23 and 2.24 was recorded in castor + groundnut treatment. Castor based cropping system with cowpea and pepper was recommended for higher land use efficiency.

The Smart Farm of Bioeconomy Campus project (2021–2023) developed a unique hub of Smart Farming technology. The resulting Smart Farm aims to accelerate the adoption of smart technologies in farms according to the United Nations Sustainable Development Goals (SDGs). Therefore, at the Smart Farm, near-market technologies and services are tested, developed, and demonstrated. The aim is to remove barriers to their adoption and accelerate innovation in the sector, significantly increasing the benefits for farmers and the related agricultural industry. The foundation of the Smart Farm is based on processing various types of data. In the project, data was intensively collected from 16 hectares of test plots where barley was cultivated. Regular measurements were taken from the soil, crops, and from machinery and tractors equipped with ISOBUS technology. Measurements included the use of wireless soil sensors (20 units), drone imaging (RGB, multispectral, and thermal cameras), satellite images, and tractor telematics data. Additionally, the usability of the 5G signal in machine guidance was measured. Based on the collected data, precision farming was planned and implemented. Automated field navigation with headland automation was compared to traditional manual driving methods. Using GIS, maps such as profitability and energy consumption maps were generated from the data. The project developed a Farmer's Data Repository, through which a farmer can license their data to the desired destination via a data delivery service. The project also demonstrated the operation of such a system, compliant with EU data regulations, in collaboration with partner companies. A comprehensive project, the Finnish Future Farm (2023–2026), has begun based on the foundation of the Smart Farm, involving companies, educational and research organizations, farmers, and stakeholders. The project will build a digital twin of the physical Smart Farm, both of which will be utilized in R&D, experimentation, and education.
Dronella kuvattujen RGB- ja NDVI-karttatasojen vertailu viljakasvuston kehityksen seurannan kannalta
Authors: Appelgren Iita , Ludwig Gilbert , Haapala Hannu
Published: April 2024

Älymaatila-hankkeessa (2021–2023) kuvattiin kahden kasvukauden (2022 ja 2023) ajan dronella hankkeen koelohkoja. Havainnointikohteena oli kaksi peltolohkoa, molempina kasvukausina lohkoilla viljeltiin ohraa. Lohkot kuvattiin kasvukausien ajan kerran viikossa eBeex-dronella. Kuvantamiseen hyödynnettiin kahta hyötykuormaa, Duet T-kameraa RGB-karttatasoja varten ja MicaSense RedEdge MX- multispektrikameraa NDVI-karttatasoja varten. Multispektrikamera kuvaa viideltä aallonpituuskaistalta ja kuvan resoluutio on 1280 x 960 px, Duet T on RGB- ja Thermal-yhdistelmäkamera, jossa RGB-kuvien resoluutio on 5,472 x 3,648 px. Lennätykseen käytettiin eMotion-ohjelmaa, jossa dronelle määritellään lentosuunnitelma. Käytetyssä lentosuunnitelmassa lentokorkeus sekä kuvien päällekkäisyysprosentti on pidetty samana kasvukauden ajan, jotta kerätty data olisi mahdollisimman samantyyppistä ja keskenään vertailukelpoista. Datan vertailukelpoisuutta pyrittiin lisäämään myös lentoajankohdan vakioimisella. Karttatasojen luominen tehtiin lentojen jälkeen Pix4D Mapper- ja Pix4D Fields-ohjelmilla. Dronella kuvatut kuvat vietiin ohjelmistoon, joka loi karttatason kuviin liitettyjen sijaintitietojen avulla. RGB-karttatasojen luomiseen käytettiin Pix4D Mapper-ohjelmistoa ja NDVI-karttatasojen luomiseen Pix4D Fields-ohjelmistoa. Tutkimuksessa vertaillaan RGB- ja NDVI-karttatasojen vahvuuksia ja heikkouksia viljakasvuston kehityksen seurannan kannalta sekä pohditaan missä kasvukauden vaiheessa eri kuvausmenetelmillä saadaan paras hyöty. Kuvantamismenetelmät tuovat erilaisia näkökulmia kasvuston tarkkailuun, NDVI-kuvilla pystytään havainnoimaan kasvuston terveyttä sekä mahdollisia stressitiloja, RGB-kuvat tarjoavat visuaalisen käsityksen viljakasvustosta, joka on ihmisenkin tulkittavissa. RGB-karttatasoista voidaan havaita paremmin rikkakasvialueita, mahdollisia kylvövirheitä sekä lakoontumista. NDVI-karttatasoista ei pystytä erottelemaan mistä lehtivihreä tulee, tällöin esimerkiksi rikkakasvit voivat luoda virheellisen kuvan kasvuston tilanteesta, jolloin NDVI-karttatason tueksi voidaan tarvita RGB-kuvia tai havaintoja pellolta. Drone datan paikkansapitävyyttä varmistettiin manuaalisesti tehdyillä kasvustohavainnoilla. Havaintopisteitä lohkoilla oli yhteensä 12 kohdassa, jokaiselta pisteeltä laskettiin orastiheyttä sekä havainnoitiin kasvuston korkeutta, versojen määrää ja kasvuastetta. Kasvustohavaintoja tehtiin kahdesti viikossa kasvukauden loppupuolelle saakka, jonka jälkeen havainnointi kertoja tehtiin kerran viikossa. Viljan kypsymisvaiheessa muutokset kasvustossa eivät ole enää yhtä suuria kuin kasvukauden alussa, jolloin tiheään tehdyt kasvustohavainnot eivät ole tarpeellisia.
Kehittyvien kotieläinyritysten johtamisen haasteet ja mahdollisuudet

Published: April 2024

Suomalaisen kotieläintuotannon rakenne ja toimintaympäristö muuttuvat nopeasti. Innovaatioiden ja hyvien käytäntöjen käyttöönotto sekä kotieläinyritysten ammattitaitoinen johtaminen voivat parantaa niiden suorituskykyä taloudellisen, sosiaalisen ja ympäristön kestävyyden näkökulmasta. Yrittäjän ja yrityksen tavoitteet määrittelevät sen, miten tilaa kehitetään ja suorituskykyä voidaan parantaa. Tavoitteiden saavuttamiseksi tarvitaan seurantaa ja tarvittaessa toimintatapojen muuttamista. Tämän tutkimuksen tavoitteena oli selvittää, mitkä ovat kehittyneiden kotieläinyritysten keskeiset tavoitteet ja haasteet.  Toisena tavoitteena oli kuvata, millaisia päätöksenteon, liikkeenjohdon ja riskinhallinnan välineitä ja työkaluja kotieläintiloilla hyödynnetään. Aineistona käytettiin syksyllä 2023 tehtyä kyselyä (N = 168). Kotieläinyrittäjien tavoitteissa korostuivat toimeentulon turvaaminen, eläinten ja ihmisten hyvinvointi. Useimmat kotieläinyrittäjät kokivat onnistuneensa eläinten hyvinvoinnin sekä työntekijöiden hyvinvoinnin turvaamisessa hyvin. Noin puolet koki saavuttaneensa hyvän taloudellisen tilanteen yrityksessään.  Alle kolmasosa yrittäjistä koki oman työhyvinvointinsa olevan hyvä. Talousjohtamisen ja riskienhallinnan työkalujen käytössä oli eroja vastaajien kesken. Yleisimmin käytettyjä talousjohtamisen työkaluja olivat hintatason sekä panos- ja tuotemarkkinoiden seuraaminen ja hankintojen kilpailutus. Myös maksuvalmiutta ja toteutuneita kustannuksia seurattiin monissa kotieläinyrityksissä. Riskienhallinnan työkaluista tärkeimmät olivat tuotannon keskeytysvakuutus ja eläintautien vahinkoja korvaava vakuutus. Tulosten perusteella taloushallinnan työkalujen käyttö korreloi riskienhallinnan työkalujen käytön ja tilakoon kanssa. Tämän tutkimuksen tulosten perusteella johtamisen ja riskienhallinnan työkalujen käytettävyyttä tulisi kehittää, jotta ne palvelisivat nykyistä paremmin kehittyvien kotieläinyritysten päätöksenteon tukena.

Published: April 2024

Bacterial bloodstream infections (BSI) are the leading cause of mortality and morbidity in pediatric solid organ transplant recipients. This systematic review aimed to pool global data from leading transplant institutions and identify the overall incidence, risk factors, and causative organisms of BSI in pediatric liver transplant recipients. A systematic review of the PubMed and OVID databases was conducted from 2000 to 2022. The initial search yielded 252 unique articles, which were independently reviewed by 2 authors. Articles that reported pediatric-specific data on BSI in isolated liver transplant patients were included, including the incidence of BSI, isolated organisms, and involved risk factors involved. This systematic review was registered with PROSPERO (ID: CRD42023403206). Fourteen articles from the United States, France, Iran, Japan, Korea, South Africa, Thailand, and Turkey were included. A total of 4,812 liver transplants were included in the final analysis. The mean patient age was 25 months (age range, 0–18 years), and 50.9% were male. The overall incidence of BSI was 23.5% (range, 14.7%–55%). The most commonly reported organisms were Staphylococcus epidermidis, Enterococcus, Klebsiella spp., and Escherichia coli. Among the risk factors studied, postope rative biliary complications, a medical history of biliary atresia, and younger age were the risk factors most commonly associated with BSI. Bacterial BSI after pediatric liver transplantation occur at a high incidence, with a unique organism profile notable for a higher percentage of gram-negative organisms.

Published: April 2024

English pre-service teachers find teaching English abroad to be a memorable experience. It influences the type of teacher they will become in the future. Through the perspective of teacher identity, this study aims to describe how two Indonesian pre-service teachers in the English education department, during a teaching practicum in the Philippines, developed their teacher identity and how they overcome the challenges. This research focused on two fourth-year students from the English Education department of a private university in Yogyakarta who completed a one-month international teaching practicum in the Philippines. The data were gathered through semi-structured interviews and subsequently investigated thematically from the perspective of the teachers' identities, and then presneted narratively. It was discovered that the biographies of the pre-service teachers served as the starting point for their teachers' identity development. Throughout the international teaching practicum, the development of their teacher identity was influenced by their emotional reactions, their teaching methods, and their symbolic representation. In the international teaching setting, the student teacher received psychological and technical assistance to overcome the challenges of their practice. This support played a crucial role in the successful completion of the program and contributed to the development of their professional identity as teachers. The findings demonstrate the importance of international teaching experience, prompting universities to prioritize the teaching practicum. Additionally, the university should expand its international exchange programs, focusing on teaching practicum programs.

Identifying Profit-Shifting to Tax Havens using statistics on Country-by-Country Reports
Authors: Castillo Murciego Ángela , López Laborda Julio
Published: April 2024

Profit-Shifting is an aggressive tax planning activity that erodes public revenues worldwide. Using statistics based on recent Country-by-Country Reports, this article identifies both descriptively and econometrically the existence of such activity by large Spanish multinationals in EU tax havens. Moreover, the paper shows that the application of the minimum Effective Tax Rate of 15% to profits generated in other EU countries by these large multinationals, within the Two-Pillar solution of the OECD/G20 Inclusive Framework, could increase Spanish tax revenue by around 2- 17% of annual corporate income tax.

Published: April 2024

This study provides new evidence on factors driving firms´ eco innovation in the European Union, based on the data of the Community Innovation Survey for the years 2008 and 2014 for eleven European countries. First, our findings reveal that the propensity to eco-innovate changes over time. Second, the propensity to eco-innovate is unequally distributed across sectors, given that it is concentrated in a few sectors. Third, we find that sectoral behavior is strongly influenced by the taxonomy of green sectors introduced by the European Union, since the propensity to innovate is higher in the carbon leakage taxonomy than in the mitigation and adaptation taxonomy. These results provide further insights into the sectoral factors driving eco-innovation diffusion. Moreover, these findings are relevant to increase environmental stringency, as they contribute to the diffusion of eco-innovation across sectors, especially in those that do not innovate.

Introduction: Recent advances have enabled organotypic culture of beating human myocardial slices that are stable for weeks. However, human myocardial samples are rare, exhibit high variability and frequently originate from diseased hearts. Thus, there is a need to adapt long-term slice culture for animal myocardium. When applied to animal cardiac slices, studies in healthy or genetically modified myocardium will be possible. We present the culture of slices from rabbit hearts, which resemble the human heart in microstructure, electrophysiology and excitation-contraction coupling.

Methods: Left ventricular myocardium from New Zealand White rabbits was cut using a vibratome and cultured in biomimetic chambers for up to 7 days (d). Electro-mechanical uncoupling agents 2,3-butanedione monoxime (BDM) and cytochalasin D (CytoD) were added during initiation of culture and effects on myocyte survival were quantified. We investigated pacing rates (0.5 Hz, 1 Hz, and 2 Hz) and hormonal supplements (cortisol, T3, catecholamines) at physiological plasma concentrations. T3 was buffered using BSA. Contractile force was recorded continuously. Glucose consumption and lactate production were measured. Whole-slice Ca2+ transients and action potentials were recorded. Effects of culture on microstructure were investigated with confocal microscopy and image analysis.

Results: Protocols for human myocardial culture resulted in sustained contracture and myocyte death in rabbit slices within 24 h, which could be prevented by transient application of a combination of BDM and CytoD. Cortisol stabilized contraction amplitude and kinetics in culture. T3 and catecholaminergic stimulation did not further improve stability. T3 and higher pacing rates increased metabolic rate and lactate production. T3 stabilized the response to β-adrenergic stimulation over 7 d. Pacing rates above 1 Hz resulted in progredient decline in contraction force. Image analysis revealed no changes in volume fractions of cardiomyocytes or measures of fibrosis over 7 d. Ca2+ transient amplitudes and responsiveness to isoprenaline were comparable after 1 d and 7 d, while Ca2+ transient duration was prolonged after 7 d in culture.

Conclusions: A workflow for rabbit myocardial culture has been established, preserving function for up to 7 d. This research underscores the importance of glucocorticoid signaling in maintaining tissue function and extending culture duration. Furthermore, BDM and CytoD appear to protect from tissue damage during the initiation phase of tissue culture.

Published: April 2024

LINK-A, also recognized as LINC01139, has emerged as a key oncological lncRNA in cancer. LINK-A is upregulated in solid and liquid tumor samples, including breast cancer, ovarian cancer, glioma, non-small-cell lung cancer, and mantle cell lymphoma. Notably, LINK-A is involved in regulating critical cancer-related pathways, such as AKT and HIF1α signaling, and is implicated in a range of oncogenic activities, including cell proliferation, apoptosis, epithelial-mesenchymal transition (EMT), cell invasion and migration, and glycolysis reprogramming. LINK-A’s differential expression and its correlation with clinical features enable it to be a promising biomarker for cancer diagnosis, prognosis, and the stratification of tumor progression. Additionally, LINK-A’s contribution to the development of resistance to cancer therapies, including AKT inhibitors and immunotherapy, underscores its potential as a therapeutic target. This review provides a comprehensive overview of the available data on LINK-A, focusing on its molecular regulatory pathways and clinical significance. By exploring the multifaceted nature of LINK-A in cancer, the review aims to offer a valuable resource for future research directions, potentially guiding the development of novel therapeutic strategies targeting this lncRNA in cancer treatment.

Published: April 2024

This study examines the unique challenges and transformations in higher education instruction during the COVID-19 pandemic, focusing on a strategic response from one chemistry department. The COVID-19 pandemic created many obstacles to providing quality instruction. To support chemistry instructors during the challenging transition to remote teaching, the leadership within one chemistry department created an initiative to ease feelings of isolation and support instructors in undergraduate teaching. Within this manuscript, we triangulate recordings of instructors’ discussions about remote teaching, course syllabi, and open-ended surveys to understand the teaching experiences of the instructors within this department during the COVID-19 pandemic. Our findings expose various points of tension instructors faced and demonstrate how the pandemic and the departmental initiative changed instructors’ teaching values. Despite the unfortunate context of the pandemic, these data reveal how this department-wide initiative has impacted the instructors and the department’s climate around teaching, which underscores the importance of collaborative efforts in navigating unprecedented educational challenges.
