Research Management as a Sustainable Career Path: Perspectives of Practising Professionals from Around the World
Authors: Dutta Madhuri , Kanaka Yatirajula Sandhya , Iqbal Sarah , Ghosh Arpita
Published: December 2024

What is new?

Research management/adminstration is not recognized as a profession in many countries. In spite of this, many research managers and administrators (RMAs) choose this career and are willing to stay in it for a long term. This paper uses global survey data to highlight factors that RMAs use to make these long-term decisions.

What was the approach?

Three global surveys (Research Administrators As A Profession, RAAAP) were analysed for the question – Why have you stayed in the profession? Data for responses to various choices within this primary question such as if they enjoyed this career, if they liked spending time with researchers and academics, if it was due to job security or good salary and whether it was the work itself, were analysed. Additionally, a few India-based RMAs were interviewed regarding their perspectives of this career through a qualitative research approach.

What is the academic impact?

Findings from this paper will help research policy makers establish a professional path for this workforce at a national level. Additionally, institutional leaders can formulate ways to retain and strengthen this workforce in their research organizations.

What is the wider impact?

The survey results provide motivation and encouragement to new RMAs and may help those deciding to take research management/administration as a career.

Published: December 2024

La agricultura digital es la evolución de la agricultura de precisión. Dentro de los avances tecnológicos más importantes en la agricultura se pueden encontrar los tractores con piloto automático, que permiten utilizar de una manera más eficiente los recursos. Por tanto, el proyecto validó la eficiencia de aplicación con pulverizadora comparando dos guías del tractor, una con piloto automático Trimble y otra con la guía manual de un operador al aplicar un compuesto a base de boro y penetrante vegetal. Se realizaron tres pases para cada una de las guías y se recopilaron los datos para posteriormente procesarlos y determinar el porcentaje de traslape presente en cada una. Además, se realizaron tres vuelos con dron, con el fin de observar por medio de imágenes multiespectrales los cambios en la vegetación, antes y posterior a la aplicación del compuesto.  Con base a ello se logró concluir que, en los pases del tractor con la guía manual del operador, los porcentajes de traslape son mayores en comparación a los obtenidos mediante el uso de la guía del piloto automático. Además, se determinó que los costos del producto y el impacto ambiental aumentan de manera significativa cuando se usa la guía manual del operador en comparación a la guía automatizada. En los índices de vegetación únicamente SAVI mostró cambios significativos, mientras que los índices EVI y AVI no se deben de utilizar en estos casos, ya que presentan datos con una alta variación y una ausencia de estos.

Библијски симболи, слике и метафоре, као и поређење Стефана Немање састарозаветним и новозаветним личностима, суштински су део Житија СветогСимеона од Светог Саве. Циљ рада јесте да представи контекст и идеолошки оквир укојем се најзаступљеније библијске паралеле јављају. У првом реду то се односи накључне сцене око којих је организована радња Житија – опис Немањиногнапуштања престола, а нарочито опис напуштања тела, односно његове смрти, као ипреноса моштију. Закључак је да је посебно наглашена паралела Стефана Немање састарозаветним Јаковом, оцем изабраног народа. Алузивни слој библијског навода,као и разлози за одабирање управо ове старозаветне личности, неопходни су заразумевање текста Житија, али и за поимање поетике средњовековне књижевностиуопште.

Stimulation de la croissance initiale de Pinus caribaea Morelet dans une plantation du Congo par contrôle de la mycorhization
Authors: Delwaulle J.C. , Garbaye J. , Okombi G.
Published: December 2024

Les pins ne peuvent être plantés avec succès en Afrique intertropicale que par l'introduction simultanée de champignons ectomycorhiziens adaptés, qui font défaut dans les associations indigènes. Il était autrefois courant en Afrique d'inoculer régulièrement les pépinières avec de la terre provenant de plantations existantes afin de maintenir la mycorhization. Les résultats étaient souvent décevants, car la plupart des mycorhizes étaient dues à Rhizopogon luteolus, un champignon qui supporte mal la sécheresse et les hautes températures.Il a été récemment démontré que d'autres souches pures peuvent contribuer à améliorer la croissance des jeunes plants. C'est notamment le cas de Pisolithus tinctorius.Cet article résume les résultats des essais menés à ce sujet dans la région de Pointe Noire.

Yunus Nefesli Bir Şair: Kaygusuz Abdâl
Authors: Öksüz Yılmaz
Published: December 2024

Anadolu’nun 13. Yüzyılı, fetih hareketlerinin büyük ölçüde tamamlandığı; Abdâllık, Babaîlik, Bektâşîlik, Kalenderîlik, Mevlevîlik gibi muhtelif tarikatların teşekkül ettiği; imar faaliyetleri yanında çeşitli kollarıyla edebiyatın filizlendiği bir dönemdir. Bu zaman diliminde, birçok şair yetişmekle birlikte yüzyıla rengini veren simalardan birisi Yunus Emre’dir. O, ilmî eserlerde Arapçanın, sanat ürünlerinde Farsçanın egemen olduğu bu dönemde, tasavvufî düşüncenin hakikatlarını sade bir Türkçe ile sunmayı başarmış ve Anadolu sahasında kendisinden sonra gelen birçok şaire öncülük etmiştir. Aşık Yunus’tan Edib Harâbî’ye uzanan bu şairler silsilesinin önemli bir halkası, Bektâşî edebiyatında mühim bir mevkii bulunan Kaygusuz Abdâl’dır. Yunus’un muhtelif şairler üzerindeki tesiri, akademik camianın dikkatini çekmiş ve buna yönelik birtakım çalışmalar yapılmıştır. Ancak, onun kadim takipçisi olan Kaygusuz’un bu yönüne dair kapsamlı bir çalışma yapılmamıştır. Bu makalede, şairlerin divanları ve Cemal Kurnaz ile Mustafa Tatcı’nın hazırladığı şathiyye mecmuası ekseninde Kaygusuz’un şiirlerinde Yunus’un tesiri incelenmiştir. Kafiye, redif ve ifade yönünden Yunus’u hatırlatan şair, selefi gibi alegorik üslûba rağbet göstermiş; aşkın kıymeti, âşığın kimliği, gönlün kararsızlığı ve kendini bilmek gibi konuları Yunusça söylemiştir. Yunus tarzını kendi özgünlüğü içerisinde sürdüren şair, aynı zamanda bu tarzın Bektâşî edebiyatına intikalinde önemli bir rol üstlenmiştir.
An Immense Portugal: The Fate of Being a Colonial Empire
Authors: Fornari Jose
Published: December 2024

In 1973, Brazilian musician Chico Buarque, in collaboration with Mozambican poet Ruy Guerra, composed Fado Tropical for the play Calabar. Set in the 16th century during the Dutch invasion of northeastern Brazil, the play tells the story of Calabar, a mixed-race entrepreneur who switches allegiances, shifting his support from the Portuguese Empire to aiding the Dutch Republic in its invasion. Fado Tropical satirizes the aspirations of the colonial elite, who dreamed of transforming Brazil into an "immense Portugal," awkwardly culminating in a “colonial empire.” Written during Brazil's repressive military dictatorship and shortly before Portugal's Carnation Revolution, both the song and the play were initially censored. Fado Tropical skillfully employs the musical tradition of fado (Portugal’s most renowned musical genre) to deliver a biting critique of colonialism. The article aims to analyze the song in relation to its historical period. The method used is a discussion of its poetic and musical construction, and how both elements interact with various socio-cultural movements—from modernism to the cultural and artistic critiques of oppression that followed the period of dictatorship. The conclusion is that the satire in this song also conveys a strong sense of nihilism, suggesting a future where Brazil, despite its vastness and immense potential, is doomed to always remain a colony—even if one day it becomes an empire, it will be colonial empire.

Le changement climatique constitue une menace pour l’élevage en raison de ses conséquences sur les performances des animaux et sur la disponibilité des ressources pastorales. Les systèmes sylvopastoraux et agrosylvopastoraux sont des solutions pour concilier production animale durable et changement climatique. Ce document synthétise la littérature existante sur la diversité de ces systèmes d’élevage dans les zones de savanes et les régions côtières d’Afrique de l’Ouest, sur leurs contributions à l’adaptation et à l’atténuation du changement climatique, ainsi qu’à l’amélioration de la productivité des animaux et à la sécurité alimentaire des ménages. Les résultats de cette synthèse montrent que les arbres constituent des ressources alimentaires pour les animaux durant la période de soudure (absence de fourrages s’étendant généralement de mars à mai), ce qui améliore leur production. Ils constituent également de véritables sources d’atténuation au changement climatique.

Genetic Contributions to Autism Spectrum Disorder: A Review of Recent Advances
Authors: Silva Mariana Oliveira , Rodrigues Flávia Melo , Silva Maria Beatriz Garcia , Gigonzac Marc Alexandre Duarte , Gigonzac Thaís Cidália Vieira
Published: December 2024

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition with a multifactorial origin and significant genetic contribution. It is characterized by difficulties in social interaction, communication, and the presence of repetitive behaviors, often associated with comorbidities such as intellectual disability and Attention Deficit Hyperactivity Disorder (ADHD). This integrative review analyzed articles published in the last five years to explore relevant genes related to ASD and neurodevelopment. Genes such as MYT1L, ZNF292, AUTS2, and regulatory genes involved in the production of microRNAs were highlighted, demonstrating their relationship with critical processes such as neurogenesis and synaptogenesis. Genes such as FGFR2 and KMT5B have been strongly associated with neurodevelopmental disorders, including autism and ADHD, underscoring their importance in understanding the genetic basis of these conditions. Additionally, the identification of specific variants, such as PTEN p.Ile135Leu, and their relationship with changes in neurogenesis, neural maturation, and synaptic function highlights the need for more in-depth studies on the molecular pathways regulating these genes expression. The findings reinforce the genetic heterogeneity of ASD and suggest potential targets for personalized therapies within the context of precision medicine. However, the importance of incorporating epigenetic and environmental factors into analyses is emphasized to achieve a more comprehensive understanding of gene-environment interactions and their clinical implications.
Optimizing Cassava Growth with Localized Struvite Application: Root Proliferation and Fertilization Efficiency

Cassava is a root storage crop that is important to the starch industry and food security. We studied sustainable fertilization of cassava using local placement of struvite, a fertilizer recovered from wastewater, rich in nitrogen, phosphorus, and magnesium. We asked if struvite is a suitable fertilizer for cassava, if it is likely to spread through the substrate (leach), and if roots can proliferate and utilize a concentrated placement of struvite. Cassava was grown in rhizoboxes under different fertilizer placement strategies: unfertilized control, homogenous fertilizer distribution in the top 20 cm (‘homogenized’), a strip placement (‘layer’) at 20 cm depth, and a localized ‘depot’ at the same depth. Shoot and root growth responses were monitored over 8 weeks. Cassava growth was significantly improved with struvite fertilization. The fertilizer remained localized, with minimal spread during the 8 weeks of experimentation. Both the ‘layer’ and ‘homogenized’ struvite placements resulted in comparable biomass production, significantly greater than the unfertilized treatment. Plants in the ‘depot’ placement initially grew similar to the unfertilized treatment as roots took time to locate and proliferate into the fertilizer depot. Afterwards, plants in the ‘depot’ treatment grew quickly resulting in an intermediate biomass at harvest. Notably, cassava exhibited strong root proliferation in response to concentrated struvite, which did not compromise deep rooting but instead appeared to enhance it, increasing specific root length. These findings suggest that strip fertilization with struvite may offer a sustainable fertilization strategy for cassava, warranting further investigation in field trials.

Authors: JIN Qian , Zheng Yu-xuan , Pan Ming-quan , Zhang Xiao-man , Zhang Ai-bing , Lai Shang-kun
Published: December 2024

Sorghum is a key global crop with substantial economic importance. Implementing green pest management for sorghum is crucial for promoting ecological balance and reducing reliance on chemical pesticides. This study assesses the impact of green pest management on arthropod biodiversity and sorghum yield and quality. Over two years, using Malaise trapping and DNA metabarcoding, we found that green pest management significantly enhanced arthropod diversity and shifted species composition, notably increasing Hymenoptera abundance. Although sorghum yield metrics were higher in the green group compared to chemical control group, these differences were not statistically significant. However, the green group exhibited improved quality with lower crude fat and higher levels of crude protein, starch, and amylopectin. These findings underscore the benefits of green pest management in fostering biodiversity and enhancing sorghum quality.
Single-Step GWAS Multi-Trait Threshold-Linear Model for Growth Rate and Heteroblasty in Eucalyptus globulus
Authors: Gonzalez Milena , Aguilar Ignacio , Quezada Marianella , Balmelli Gustavo
Published: December 2024

Genome-wide association studies (GWAS) have provided significant insights into identifying variants associated with complex traits, but they have contributed little to the study of categorical data. The aim of this study was to identify genomic regions associated with quantitative traits (growth) and categorical traits (heteroblasty) in a tree breeding population of Eucalyptus globulus. Tree growth was measured as total height (TH) and diameter at breast height (DBH). Heterobasty was assed as the precocity of change from juvenile to adult foliage (ADFO). All traits were evaluated at 14 and 21 months. A multi-trait threshold-linear model was developed following the single-step genomic selection methodology. Variance components were estimated using Gibbs sampling process. Genetic correlations (rg) and the narrow sense heritability (h2) for all traits were estimated. Windows of 0.2 Mb were used and their variances were calculated. Only the windows with estimated variance higher than 1% were considered. The rg ranging from 0.51 to 0.97. The h2 were high for ADFO (0.83-0.84), and lower for HT (0.37) and DBH (0.53). In growth traits, no QTL were found that explained more than 1% of the variance. However, two genomic regions were found related with ADFO, in the chromosome 3 and 11.

This study presents the results of an experimental investigation conducted on a 2:3 scale model of a two-storey stone masonry building. We tested the model on the UniKORE L.E.D.A. lab shake table, simulating the Mw 6.3 earthquake ground motion that struck L’Aquila, Italy, on April 06, 2009, with progressively increasing peak acceleration levels. We installed a network of accelerometric sensors on the model to capture its structural behaviour under seismic excitation. Medium- to lower-cost MEMS accelerometers (Classes A and B) were compared with traditional piezoelectric sensors commonly used in Structural Health Monitoring (SHM). The experiment assessed the structural performance and damage progression of masonry buildings subjected to realistic earthquake inputs. Additionally, the collected data provided valuable insights into the effectiveness of different sensor types and configurations in detecting key vibrational and failure patterns. All the sensors were able to accurately measure the dynamic response during seismic excitation. However, not all of them were suitable for Operational Modal Analysis (OMA) in noisy environments, where their self-noise represents a crucial factor. This suggests that the self-noise of the MEMS accelerometers must be less than 1 µg/√Hz, or preferably below 0.5 µg/√Hz, to obtain good results from the OMA analysis. Therefore, we recommend ultra-low-noise sensors for detecting differences in structural behaviour before and after seismic events. Our findings provide valuable insights into the seismic vulnerability of masonry structures and effectiveness of sensors in detecting damage. The management of buildings in earthquake-prone areas can benefit from these specifications.

Volarization of Banana Peel Waste into Advance Adsorbent Beads for the Removal of Emerging Pollutants from Wastewater
Authors: Boyle Olivia , Xiao Bo , Mangwandi Chirangano
Published: December 2024

This study addresses environmental concerns by utilizing banana peel waste to develop innovative adsorbent materials for wastewater treatment, aligning with circular economy principles. Spherical beads were synthesized from sodium alginate mixed with various banana peel-based materials, including pure powder (PBP), activated carbon (AC), and magnetic activated carbon (MAC). These beads were evaluated for their efficiency in removing tetracycline (TC) and hexavalent chromium (Cr(VI)) as model pollutants representing antibiotics and heavy metals, respectively. Characterization of the beads revealed functional groups and thermal stability conducive to effective adsorption. Adsorption trials demonstrated that MAC beads achieved the highest removal efficiencies, up to 92% for TC and 79% for Cr(VI). The adsorption process followed pseudo-second-order kinetics and Langmuir isotherms. Remarkably, the beads retained significant adsorption capacity across reuse cycles, indicating their regenerative potential. Comparisons with other adsorbents highlight the competitive performance of these banana peel-based materials. The results emphasize the potential of banana peel-derived adsorbents as cost-effective, sustainable solutions for mitigating emerging pollutants in water systems, promoting waste valorization and environmental protection.

Published: December 2024

Background: Total gastrectomy with D2 lymph node dissection is standard for resectable esophagogastric junctional and gastric cancer, but high morbidity challenges perioperative care. ERAS guidelines advise against routine drains, yet conflicting evidence leads to inconsistent practice. Methods: The DRAG (DRains After Gastrectomy) Trial is a prospective, non-randomized study conducted from February 2020 to March 2023 at the 1st Propaedeutic Surgery Department, Hippocration General Hospital, Athens. Patients undergoing open D2 total gastrectomy had perianastomotic drains placed based on newly established criteria, offering a more tailored approach. Immediate and short-term postoperative outcomes, including recovery milestones and complications, were assessed. Results: Sixty patients were included, with 40 receiving a drain. The non-drain group had significantly lower pain scores, earlier mobilization, less postoperative nausea and vomiting, and a shorter hospital stay. Among those with complications, significant differences in surgical site infections, delayed mobilization, extra-abdominal issues, length of stay, readmissions, and reoperations suggest that drain use may increase complications and hinder recovery. Conclusion: Our study suggests that routine prophylactic drain use can be avoided in gastrectomy for esophagogastric junctional and gastric cancer when experienced surgeons in high-volume centers follow predefined criteria. Implementing these criteria may improve patient outcomes and reduce complications.
Evaluation of Genetic Diversity in Wild Emmer Wheat (Triticum dicoccoides) and Durum Wheat (Triticum durum) Accessions Using Caat and SCoT Markers
Authors: Çakır Esra
Published: December 2024

Wild emmer is one of the progenitors of wheat, with a high genetic potential for breeding. Continuous evaluations of emmer and other progenitor species are necessary for long-term improvement in yield, agronomic, and stress-related traits. For this purpose, genetic diversity and relationships among 43 wild emmer (Triticum dicoccoides) and 5 durum wheat (Triticum durum) accessions were determined using two DNA marker systems, CAAT box-derived polymorphism (CBDP) and start codon targeted (SCoT) markers. CAAT and SCoT markers generated 63 and 76 polymorphic bands, averaging 9 and 7.6 bands per primer, respectively. The discriminating power, effective multiplex ratio, expected heterozygosity, mean heterozygosity, marker index, polymorphism information content, and resolving power parameters obtained for both marker systems showed the high efficiency of these markers in detecting genetic variation in wild emmer and durum wheat. The results showed that CAAT and SCoT markers with average polymorphism are suitable marker systems for detecting genetic variation between a pool of accessions or populations. These markers would be used for gene-targeted breeding and the results suggest that genetic analysis with these markers would be practical for crop improvement and development programs.

Authors: Chatterjee Priyadarshini , Siddiqui Shadab , R Srikanth
Published: December 2024

Due to a lack of screening facilities, knowledgeable professionals, and public awareness, cervical cancer continues to rank among the most common malignancies among women, especially in developing nations. Expert review is frequently necessary for current screening methods such the Papanicolaou (Pap) test, histopathology, visual inspection with acetic acid (VIA), and the human papillomavirus (HPV) test. In this study, we address the challenge of colposcopy image classification by developing a deep convolutional neural network enhanced with squeeze-and-excitation (SE) blocks and residual connections to improve feature extraction and classification accuracy. The model leverages SE blocks to emphasize critical features and residual connections to ensure efficient gradient flow in a deep architecture. We conducted hyperparameter fine-tuning and applied Principal Component Analysis (PCA) to optimize performance. The model’s initial training and validation accuracy were 96.72% and 96.23%, respectively. Training accuracy increased to 98.12% with a validation accuracy of 98.01% after fine-tuning, proving the efficacy of our strategy. These results show that adding SE blocks and residual connections significantly improves the model’s competency to detect cervical lesions in colposcopy images. According to the results, this design may offer strong support for automated cervical cancer screening, which might help with early diagnosis and detection.

Background/Objectives: The number of children with special health care needs (CSHCN) has increased considerably owing to medical advances. However, the specifics of care that contribute to the well-being of CSHCN and their families and guarantee home nurturing have not been clarified. Methods: This exploratory single case study adhered to Yin's approach for case studies and used explanation-building methods for data analysis. Interviews were conducted with the staff in charge of CSHCN cases in a Japanese infant home, and information was collected from the records. Participant interview data and other data sources provided detailed case descriptions of care practices and outcomes. Results: Interviews on CSHCN with autoinflammatory diseases were conducted with three staff members and the child's mother. Data resources included childcare records, hospital visitation records, growth and development data, and case-related documents. The following factors were found to lead to a stronger system of care: accompanying growth through trial and error, supporting the family while sharing the child's growth and working with multiple agencies, and continuing to explore possibilities and support for family childcare. Conclusions: This case study describes the actual care provided to CSHCNs and their families in a single-infant home, revealing factors that lead to a stronger system of care. Here, the infant home provided a tried-and-true approach to CSHCNs and their families with multifaceted needs and attended to diverse child-development aspects while simultaneously supporting the family.
Research on the Catalytic Behavior of Ni-VC/SiO2 Catalyst for Methane Cracking
Authors: Li Shoufu , Ding Aizhong
Published: December 2024

With the growth of global energy demand and the reduction of fossil fuels, the search for clean energy has become particularly urgent. Hydrogen energy, due to its cleanliness and high efficiency, is regarded as an ideal alternative energy source. Methane catalytic cracking technology, as an effective way to produce hydrogen, has significant economic and environmental value.This study focuses on the application of vanadium-based catalysts in biogas cracking for hydrogen production. Vanadium-based catalysts have shown great potential in the dehydrogenation of hydrocarbons due to their cost-effectiveness, environmental compatibility, high catalytic activity, and stability. An innovative one-step method was used to prepare Ni-VC/TiO2 composite catalysts, and the impact of vanadium carbide (VC) content on the performance of the catalyst was studied. The addition of VC not only optimized the catalyst's active surface area but also enhanced its conductivity and electron transfer capability, thereby improving catalytic efficiency.Experimental results indicate that an increase in VC content leads to a decrease in the specific surface area and pore volume of the catalyst, but an increase in pore size, which is beneficial for the adsorption and diffusion of gas molecules. Moreover, the reaction temperature has a significant effect on the performance of the catalyst: at 500°C, the 10Ni-5VC/TiO2 catalyst exhibited the highest stability and hydrogen production rate. However, at higher temperatures, the methane conversion rate and hydrogen yield will drop sharply due to the increased graphitization of coke, which accelerates the deactivation of the catalyst.Through regeneration experiments, we found that using CO2 as an activator at 600°C can effectively restore the activity of the catalyst. However, as the number of regenerations increases, the performance of the catalyst gradually decreases, which is related to the increase in Ni grain size and the formation of surface amorphous coke. SEM and TEM analysis showed that coke mainly exists in the form of filamentous carbon, which affects the long-term stability of the catalyst.

Chronic granulomatous invasive fungal sinusitis (CGIFS) is an uncommon type of invasive sinusitis which is characteristically seen in immunocompetent individuals. Common clinical manifestations of this condition include proptosis, cheek swelling, and headache. The pathogenic organism is Aspergillus in majority of reported cases. Diagnosis is made by histopathological and microbiological examination of tissue specimens. Due to its expansible nature bone erosion is also associated with this condition. Treatment is surgical clearance/debulking followed by long term antifungal therapy. Here we report a case of 31 year old male presented with right side cheek swelling. Patient underwent medial maxillectomy and diagnosed as CGIFS. Patient was put on oral voriconazole for 3 months. To conclude CGIFS is rare variant of invasive fungal sinusitis which may mimic malignancy or granulomatous diseases such as tuberculosis, rhinoscleroma and rhinoscleroma. Accurate diagnosis is of utmost importance in providing management for CGIFS.
Measuring Localness in E-Commerce Using the Expenses Localness Indicators Model
Authors: Parastatidou Georgia , Chatzis Vassilios
Published: December 2024

This paper presents a novel method for measuring the localness of a company in an innovative and reliable way, motivated by the growing consumer interest in purchasing local products and supporting local economies. The proposed Expenses Localness Indicators (ELI) model uses existing data from information systems to define Localness Indicators, and incorporates Localness Levels based on geographic and economic criteria. It can be applied to any type of financial entity and overcomes the difficulty of defining localness in e-commerce companies or digital businesses in general. Previous studies have examined the impact of localness and investigated its effectiveness as a branding strategy for managers, mainly through product traceability. The ELI model uses as data the expenses of a company paid to other financial entities. The Expenses Localness Indicators are determined based on the distribution of these payments combined with the localness of the paid financial entities. These Indicators represent the degree of localness as a percentage, ranging from 0% (non-local) to 100% (fully local), and may vary over time. The results of the presented examples indicate that a company’s localness increases as it spends more of its expenses on local financial entities and vice versa. Specific strategies have been tested using synthetic data that demonstrate the correct functioning of the model’s indicators. The ELI model could be used to provide reliable and certifiable information to consumers who want to know where their money goes when they buy products. It could also be established as a valid indicator of localness to provide information that researchers, government agencies and professionals can use to promote local entrepreneurship.

The increasing use of large glass surfaces in modern architecture requires robust adhesive solutions that balance aesthetic appeal with structural resilience, particularly in timber-glass applications. This study examines the influence of primer treatments on the shear performance of timber-glass adhesive joints, employing a combination of experimental testing and simulation techniques. Double-lap shear tests with epoxy adhesives assess the impact of various surface treatments on joint stiffness, shear stress distribution, and deformation. Additionally, a finite element model is developed to simulate joint behavior, evaluate failure modes, and analyze displacement patterns. Results indicate that primer applications notably enhance structural integrity by reducing displacement and increasing joint stability, thereby supporting more durable timber-glass assemblies. These findings offer valuable insights for advancing adhesive technologies in architectural components, enabling a closer alignment between structural performance and design innovation in timber-glass systems.

Parkinson’s disease (PD) is a neurodegenerative disorder with a high variability of age at onset, disease severity, and progression. This suggests that other factors, including genetic, environ-mental, or biological factors, are at play in PD. Loss of PINK1 causes a recessive form of PD and is typically fully penetrant; however, it features a wide range in disease onset, further supporting the existence of protective factors, endogenous or exogenous, to play a role. Loss of Pink1 in Drosophila melanogaster results in locomotion deficits, which are also observed in PINK1-related PD in humans. In flies, Pink1 deficiency induces defects in the ability to fly; none-theless, around ten percent of the mutant flies are still capable of flying, indicating that advanta-geous factors affecting penetrance also exist in flies. Here, we aimed to identify the mechanisms underlying this reduced penetrance in Pink1-deficient flies. We performed genetic screening in pink1-mutant flies to identify RNA expression alterations affecting the flying ability. The most important biological processes involved were transcription-al and translational activities, endoplasmic reticulum (ER) regulation, and flagellated movement and microtubule organization. We validated 2 ER-related proteins, zonda and windbeutel, to positively affect the flying ability of Pink1-deficient flies. Thus, our data suggest that these pro-cesses are involved in the reduced penetrance and that influencing them may be beneficial for Pink1 deficiency.
