Multicriteria evaluation of sustainability in last-mile logistics: a review
Authors: Corti Franco , D’Alpaos Chiara , Greco Luciano
Published: January 2025

As cities continue to grow, there is a pressing need to enhance the quality of life for citizens while also tackling challenges such as the rising demand for urban freight deliveries and environmental sustainability goals. However, the competition between people and goods for limited space in urban areas creates pressure on local authorities and piques the interest of consultants and researchers. This study examines how sustainability is tackled when decisionmakers and stakeholders assess alternative solutions with multi-criteria methods in different urban logistics contexts. A multi-step systematic review has been performed to examine the use of multi-criteria analysis in the specific multidisciplinary sector of urban freight logistics and how sustainability is defined and pursued by identifying 56 papers published between 2011 and 2023addressing problems related to sustainable urban logistics solutions. Despite the growing number of applications and scientific publications, a standard methodological framework is lacking in selecting methods and criteria to evaluate sustainable logistics solutions. To fill this gap, this paper aims to map the problems addressed and the methods applied, the stakeholders involved as actors, their objectives, and the criteria chosen to support their choices. This paper investigates the decision-making process, actors and sources, and which criteria are chosen when the intent is to pursue sustainable solutions. Future research could delve deeper into the weighting process among criteria to elucidate the coherence between stated goals and actual decisions. Such research could offer valuable insights into how decisions are made and help identify areas for improvement.

Authors: Satea H. Alnajjar
Published: January 2025

Abstract: Optical wireless communications are an alternative approach to address the challenges in completing the deployment of terrestrial networks to underwater optical wireless communication (UWOC) environments. This study aims to investigate the effectiveness of a free-space optical (FSO) channel system to feed light-fidelity Li-Fi-closed underwater platforms that, in turn, supply the non-line-of-sight (NLOS) link with the proper communications. The FSO link faces the challenge of attenuation due to the surrounding environment, which in turn negatively affects the communication link reaching the end user underwater via Li-Fi underwater platforms according to the proposed scenario. measurements show a strong signal at the receiver, it indicates that the reflection is effective and that the system can successfully transmit information using NLOS methods. Multipath with apt transmit power and NLOS transmission surface incident angle selection achieved ambitious results and sustainable connectivity even in rainy situations surrounding the FSO system.

O artigo tem por objetivo discorrer experiencias de professoras em um projeto 24 horas intitulado “Paisagismo no ambiente escolar” realizado em uma escola estadual no município de Cáceres/MT com crianças do ensino fundamental. O intuito da escrita do presente artigo é de instigar um repensar nas políticas públicas da educação no que se refere ao contato das crianças com a natureza. Sabemos que o termo “meio ambiente” é considerado pelo pensamento geral de estudiosos, como sinônimo de natureza, local a ser apreciado, respeitado e preservado, sendo assim, é de extrema relevância estabelecer a noção no ser humano de pertencimento ao meio ambiente, no qual possui vínculos naturais para a sua sobrevivência, desde pequeno. O termo paisagismo de acordo com Rebouças (2004) é a resultante relação entre o clima e o solo, que são os processos evolutivos do homem sobre a natureza frente as suas vontades impostas pela sociedade. O projeto 24 horas foi pensado com propósito de possibilitar um ambiente onde as crianças pudessem estar em contato com plantio e organização como forma de preservar a natureza.

Approche probabiliste de la dégradation des réseaux polymères
Authors: GILORMINI Pierre
Published: January 2025

Pour les réseaux subissant une dégradation par coupure de chaines, la densité de réticulation va progressivement chuter alors que la fraction soluble va augmenter. Le point de « dégel » est atteint quand la densité de chaine élastiquement atteint est nulle. Ce chapitre présente une approche probabiliste qui permet de prédire l’évolution de la densité de réticulation (c’est-à-dire du module élastique), et de la fraction soluble, en fonction du taux d’avancement du processus de dégradation. Cette approche est appliquée à différentes configurations de réseaux différant par la fonctionnalité des nœuds de réticulation et le nombre de groupements réactifs porté par chaque chaine élastiquement active.

Published: January 2025

Le BIM, malgré ses avantages pour la gestion collaborative des données de construction, rencontre des problèmes d’interopérabilité et de résistance au changement. Les normes et protocoles sont insuffisamment partagés, et les informations sont souvent incohérentes et mal consolidées. La transition vers une collaboration augmentée par le BIM nécessite une stratégie numérique structurée, une adaptation des pratiques et des modèles économiques, ainsi qu'une meilleure gestion de l'information, notamment à travers des normes comme l'ISO 19650. La réussite des projets de construction 4.0 dépendra de la capacité à combiner ces concepts pour améliorer la collaboration et la prise de décision.
Dynamical imprints on precipitation cluster statistics across a hierarchy of high-resolution simulations
Authors: Stephan Claudia Christine , Stevens Bjorn
Published: January 2025

Abstract. Tropical precipitation cluster area and intensity distributions follow power laws, but the physical processes responsible for this macroscopic behavior remain unknown. We analyze global simulations at 10 km horizontal resolution that are configured to have drastically varying degrees of realism, ranging from global radiative–convective equilibrium to fully realistic atmospheric simulations, to investigate how dynamics influence precipitation statistics. We find the presence of stirring and large-scale vertical overturning, as associated with substantial planetary- and synoptic-scale variability, to be key to having cluster statistics approach power laws. The presence of such large-scale dynamics is reflected in steep vertical velocity spectra. Large-scale rising and sinking modulate the column water vapor and temperature field, leading to a heterogeneous distribution of moist and dry patches and regions of strong mass flux, in which large precipitation clusters form. Our findings suggest that power laws in Earth's precipitation cluster statistics stem from the robust power laws of atmospheric motions.

Abstract. Grasslands make up the majority of agricultural land and provide fodder for livestock. Information on grassland yield is very limited as the fodder is directly used at the farms. Data on grassland yields would be needed, however, to inform politics and stakeholders on grassland ecosystem services and inter-annual variations. Grassland yield patterns are often varying on small scales in Germany and estimations are further complicated by missing information on grassland management. Here, we present three different approaches to estimate annual grassland yield for a study region in southern Germany. We apply (i) a model derived from field samples, satellite data and mowing information (RS), (ii) the biogeochemical process-based model LandscapeDNDC (LDNDC) and (iii) a rule-set approach based on field measurements and spatial information on grassland productivity (RVA) to derive grassland yields per parcel for the Ammer catchment area in 2019. All three approaches reach plausible results of annual yields of around 4–9 t/ha and show overlapping as well as diverging spatial patterns. For example, direct comparisons show that higher yields were derived with LDNDC compared to RS and RVA, in particular related to the first cut and for grasslands mown only one or two times per year. The mowing frequency was found to be the most important influencing factor for grassland yields of all three approaches. There were no significant differences found in the effect of abiotic influencing factors, such as climate or elevation, on grassland yields derived from the different approaches. The potentials and limitations of the three approaches are analysed and discussed in depth, such as the level of detail of required input data, or the capability of regional and inter-annual yield estimations. For the first time, three different approaches to estimate grassland yields were compared in depth resulting in new insights in their potentials and limitations. Grassland productivity maps provide the basis for long-term analyses of climate and management impacts and comprehensive studies of the functions of grassland ecosystems.
Do land models miss key soil hydrological processes controlling soil moisture memory?

Published: January 2025

Abstract. Soil moisture memory (SMM), which refers to how long a perturbation in soil moisture (SM) can last, is critical for understanding climatic, hydrological, and ecosystem interactions. Most land surface models (LSMs) tend to overestimate surface soil moisture and its persistency (or SMM), sustaining spuriously large soil surface evaporation during dry-down periods. We attempt to answer a question: do LSMs miss or misrepresent key hydrological processes controlling SMM? We use a version of Noah-MP with advanced hydrology that explicitly represents preferential flow and surface ponding and provides optional schemes of soil hydraulics. We test the effects of these processes, which are generally missed by most LSMs in SMM. We compare SMMs computed from various Noah-MP configurations against that derived from the Soil Moisture Active Passive (SMAP) L3 soil moisture and in situ measurements from the International Soil Moisture Network (ISMN) from the years 2015 to 2019 over the contiguous United States (CONUS). The results suggest that (1) soil hydraulics plays a dominant role and the Van Genuchten hydraulic scheme reduces the overestimation of the long-term surface SMM produced by the Brooks–Corey scheme, which is commonly used in LSMs; (2) explicitly representing surface ponding enhances SMM for both the surface layer and the root zone; and (3) representing preferential flow improves the overall representation of soil moisture dynamics. The combination of these missing schemes can significantly improve the long-term memory overestimation and short-term memory underestimation issues in LSMs. We suggest that LSMs for use in seasonal-to-subseasonal climate prediction should, at least, adopt the Van Genuchten hydraulic scheme.
Separating snow and ice melt using water stable isotopes and glacio-hydrological modelling: towards improving the application of isotope analyses in highly glacierized catchments
Authors: Müller Tom , Fischer Mauro , Lane Stuart N. , Schaefli Bettina
Published: January 2025

Abstract. Glacio-hydrological models are widely used for estimating current and future streamflow across spatial scales, utilizing various data sources, notably observed streamflow and snow and/or ice accumulation, as well as ablation observations. However, modelling highly glacierized catchments poses challenges due to data scarcity and complex spatio-temporal meteorological conditions, leading to input data uncertainty and potential misestimation of the contribution of snow and ice melt to streamflow. Some studies propose using water stable isotopes to estimate shares of rain, snow and ice in streamflow, yet the choice of the isotopic composition of these water sources significantly impacts results. This study presents a combined isotopic and glacio-hydrological model which provides catchment-integrated snow and ice melt isotopic compositions during an entire melting season. These isotopic compositions are then used to estimate the seasonal shares of snow and ice melt in streamflow for the Otemma catchment in the Swiss Alps. The model leverages available meteorological station data (air temperature, precipitation and radiation), ice mass balance data and snow cover maps to model and automatically calibrate the catchment-scale snow and ice mass balances. The isotopic module, building on prior work by Ala-Aho et al. (2017a), estimates seasonal isotopic compositions of precipitation, snow and ice. The runoff generation and transfer module relies on a combined routing and reservoir approach and is calibrated based on measured streamflow and isotopic data. Results reveal challenges in distinguishing snow and ice melt isotopic values in summer, rendering a reliable separation between the two sources difficult. The modelling of catchment-wide snowmelt isotopic composition proves challenging due to uncertainties in precipitation lapse rate, mass exchanges during rain-on-snow events and snow fractionation. The study delves into these processes and their impact on model results and suggests guidelines for future models. It concludes that water stable isotopes alone cannot reliably separate snow and ice melt shares for temperate alpine glaciers. However, combining isotopes with glacio-hydrological modelling enhances hydrologic parameter identifiability, in particular those related to runoff transfer to the stream, and improves mass balance estimations.
Pressurised water flow in fractured permafrost rocks revealed by borehole temperature, electrical resistivity tomography, and piezometric pressure
Authors: Offer Maike , Weber Samuel , Krautblatter Michael , Hartmeyer Ingo , Keuschnig Markus
Published: January 2025

Abstract. Rock slope instabilities and failures from permafrost rocks are among the most significant alpine hazards in a changing climate and represent considerable threats to high-alpine infrastructure. While permafrost degradation is commonly attributed to rising air temperature and slow thermal heat propagation in rocks, the profound impact of water flow in bedrock permafrost on warming processes is increasingly recognised. However, quantifying the role of water flow remains challenging, primarily due to the complexities associated with direct observation and the transient nature of water dynamics in rock slope systems. To overcome the lack of a quantitative assessment, we combine datasets of rock temperature measured in two deep boreholes (2016–2023), with electrical resistivity tomography measurements repeated monthly in 2013 and 2023; the site-specific temperature–resistivity relation determined in the laboratory with samples from the study area; and borehole piezometer data. Field measurements were carried out at the permafrost-affected north flank of the Kitzsteinhorn (Hohe Tauern range, Austria), which is characterised by significant water outflow from open fractures during the melt season. Borehole temperature data demonstrate a seasonal maximum of the permafrost active layer of 4–5 m. They further show abrupt temperature changes (∼ 0.2–0.7 °C) at 2, 3, and 5 m depth during periods with enhanced water flow and temperature regime changes between 2016–2019 and 2020–2022 at 10 and 15 m depth, which cannot be explained solely by conductive heat transfer. Electrical resistivity measurements repeated monthly reveal a massive decrease in resistivity from June to July and the initiation of a low-resistivity (< 4 kΩ m) zone in the lower part of the rock slope in June, gradually expanding to higher rock slope sections until September. We hypothesise that the reduction in electrical resistivity of more than an order of magnitude, which coincides with abrupt changes in borehole temperature and periods of high water heads up to 11.8 m, provides certain evidence of snowmelt water infiltration into the rockwall becoming pressurised within a widespread fracture network during the thawing season. This study shows that, in addition to slow thermal heat conduction, permafrost rocks are subjected to sudden push-like warming events and long-lasting rock temperature regime changes, favouring accelerated bottom-up permafrost degradation and contributing to the build-up of hydrostatic pressure, potentially leading to slope instability.

Published: January 2025

Cesarean section is a surgical procedure to terminate pregnancy through an abdominal incision, which often causes hemodynamic changes, such as hypotension and increased heart rate due to spinal anesthesia. The Enhanced Recovery After Cesarean Section (ERACS) protocol was developed to reduce these complications through a perioperative care approach, including better pain control, early mobilization, and fluid management compared to non ERACS methods. This study aims to analyze the differences in hemodynamic parameters between ERACS and non ERACS methods in cesarean section patients with spinal anesthesia at Siti Hawa Mother and Child Hospital Padang.
This is an observational analytic study using a cross-sectional approach. The sample consisted of 72 cesarean section patients, with 36 samples for each group. Data collection was conducted prospectively from September to November 2024. The instrument used was primary data obtained through observation and recording of hemodynamic parameters on the patient’s vital sign monitor.
The results of this study showed significant differences in the average systolic pressure, diastolic pressure, and mean arterial pressure between the preoperative and intraoperative stages at 5, 10, and 15 minutes after sub arachnoid block (SAB) in both ERACS and non ERACS methods (p-value > 0.05). Meanwhile, heart rate showed a significant difference only at 15 minutes intraoperatively after spinal anesthesia (p-value < 0.05). The conclusion is that there is a difference in hemodynamics in patients undergoing cesarean section, with the ERACS method showing better hemodynamic stability compared to the non-ERACS method.

Background: Intracranial atherosclerotic stenosis (ICAS) is a major cause of ischemic stroke, posing challenges due to its progressive nature and high recurrence risk. Endovascular interventions like balloon angioplasty show promise in improving blood flow and stabilizing stenotic arteries, particularly in symptomatic ICAS (sICAS) patients unresponsive to medical therapy. This study evaluates outcomes of balloon angioplasty for sICAS at Pelni Hospital over 3.5 years.
Methods: A retrospective cohort study of 31 sICAS patients undergoing balloon angioplasty (January 2021–July 2024) assessed demographics, lesion locations, procedural success, and outcomes. Standard endovascular techniques under fluoroscopic guidance were used, focusing on procedural success, complications, and patient stability.
Results: Balloon angioplasty was successful in all patients (100%). Most lesions were in the posterior circulation, particularly the vertebrobasilar artery (54.8%), with anterior circulation lesions in the internal carotid (25.8%) and middle cerebral arteries (19.4%). Complications occurred in 2 patients (6.5%), both resulting in adverse outcomes, including death. The remaining 29 patients (93.5%) experienced no significant complications and remained stable during follow-up.
Conclusions: Balloon angioplasty demonstrates high success with low complication rates for sICAS, offering a viable therapeutic option for severe stenosis unresponsive to medical therapy. Further research is needed to confirm long-term efficacy, refine patient selection, and enhance clinical outcomes.

“Neste livro, Daniele Araújo faz uma importante discussão sobre como se estrutura a formação de professores para a Educação Especial brasileira. Do contexto inicial, de uma formação dividida entre movimentos generalistas e/ou especialistas, a autora nos convida a conhecer uma experiência bem-sucedida na Pós-Graduação Lato Sensu em Educação Especial e Inovação Tecnológica, desenvolvida a partir de parceria público-público entre a Universidade Federal Rural do Rio de Janeiro e a Fundação Cecierj. A proposta ambiciosa contou com 1484 inscritos e, a partir de uma metodologia que combinava elementos da educação a distância com fundamentos da perspectiva histórico-cultural, especialmente a ênfase no dialogismo presente nas interações síncronas, contou com baixíssimo índice de evasão, mostrando o sucesso da iniciativa. Leitura fundamental para quem atua na área da Educação Especial, da formação professores e da educação online, é um texto ao mesmo tempo denso e agradável que nos leva a boas práticas no universo educacional brasileiro.”
Relationship Between Attitude Towards Mathematics and Academic Achievement of Eleventh-Class Students
Authors: Neha Khaiwal, Satyendra Gupta
Published: January 2025

This study explores gender-based differences and the relationship between attitudes toward mathematics and academic achievement among eleventh-grade students. Mathematics plays a pivotal role in intellectual development and societal progress, yet students' attitudes toward the subject often influence their academic outcomes. This research examines the correlation between attitudes and performance, alongside potential gender-based impacts. The study involved 100 eleventh-grade students from D.A.V. Inter College in Unn Shamli, Uttar Pradesh, selected using a mixed random sampling method. Data were collected using the Attitude Towards Mathematics Scale (ATMS) and academic performance records. The ATMS assessed dimensions such as confidence, enjoyment, fear, and perceived utility, while academic achievement was measured through standardized test scores and cumulative performance. Results showed a significant positive correlation (r = 0.273, p = 0.006) between attitudes toward mathematics and academic achievement. Students with extremely favorable attitudes (67% of participants) achieved higher academic performance, with 46% scoring between 71–80 marks and 21% achieving 81–90 marks. Conversely, students with less favorable attitudes demonstrated lower academic success. Gender differences, however, were not statistically significant in either attitudes (p = 0.230) or achievement (p = 0.445). Boys, comprising 64% of the sample, exhibited slightly higher confidence levels, but overall attitudes and academic outcomes were comparable across genders. The study highlights the centrality of positive attitudes in academic success, with the mean academic achievement score at 3.13 (SD = 0.747) on a 4-point scale and the mean attitude score at 1.59 (SD = 1.006), reflecting generally favorable perceptions. Most academic achievements were in the mid-range (61–80 marks), suggesting that while attitudes significantly influence performance, external factors such as teaching quality and resources also play crucial roles. This research underscores the importance of fostering positive attitudes toward mathematics to enhance achievement. Interventions aimed at building confidence and enjoyment, alongside addressing systemic barriers like inadequate resources and rigid curricula, are recommended. Future studies should adopt longitudinal designs and explore external influences such as parental support and societal standards to deepen understanding.

Salmonella Gallinarum causes fowl typhoid, a systemic disease with significant economic and welfare implications in poultry. This study aimed to determine the Infectious Dose 50 (ID50) of S. Gallinarum in Vanaraja layer chickens and evaluate histopathological changes and immune responses. Chickens were intraperitoneally inoculated with escalating doses of S. Gallinarum (2×10⁹, 4×10⁹, 8×10⁹, and 1.6×10¹⁰ CFU), and the ID50 was estimated to be approximately 8.0×10⁹ CFU. Higher doses induced clinical symptoms, including mortality and liver damage characterized by congestion and necrosis. Serum antibody responses, specifically IgG and IgA, were significantly elevated in a dose-dependent manner. Additionally, flow cytometry (FACS) analysis revealed a marked activation of CD3+, CD4+, and CD8+ T-cells, indicating robust cellular immunity. These findings underscore the pathogenicity of S. Gallinarum and highlight the need for enhanced biosecurity measures, improved management practices, and the development of vaccines to mitigate its impact on poultry health.
Pineapple Trade Projections

Published: January 2025

This study examines data from the Philippine Statistics Authority on pineapple export trade in the Philippines from 2000 to 2022, aiming to project exports from 2023 to 2032. Statistical measures, including Kendall's tau_b and Spearman's rho, validate trend strength and robustness. Pre-processing involved outlier detection using the Z-score method and calculating stationarity through first-order differencing. The Ljung-Box test ensured model robustness by checking for autocorrelation in residuals. Various ARIMA models (ARIMA(0,1,1), ARIMA(1,1,0), ARIMA(1,1,1)), Exponential Smoothing (Brown, Damped, Holt) and Moving Average were evaluated to verify on which model best fit for forecasting. Based from the three models, the results provide evidence that across multiple metrics, the 2-year Moving Average method is the best fit for forecasting. It achieved the highest Stationary R² (0.887) and R² (0.887), and the lowest RMSE (71.589) and MAPE (6%). Notably, the moving average forecast for 2023 was 992.22 metric tons, which closely approximates the actual export figure of 939.98 metric tons. In contrast, the forecasts generated by the ARIMA model and Exponential Smoothing were significantly lower, at 470.66 metric tons and 390.88 metric tons, respectively. This indicates the superior accuracy and reliability of the Moving Average method in capturing the trends in the data. These findings aid in understanding export trade and inform policy development for food security and sustainability, and improve the pineapple export strategy for the Philippines moving forward.
The Regulation of ASN Neutrality and Political Rights in Regional Head Elections: Legal Challenges and Solutions

Published: January 2025

The issue of violations of neutrality among State Civil Apparatus (ASN) has sparked public discourse about revoking ASN's political rights. A 2020 survey by the Election and Democracy Syndicate (SPD) revealed that 28% of respondents supported revoking ASN’s political rights, similar to the restrictions applied to the military and police (TNI/Polri). This proposal is seen as a solution to address persistent violations of ASN neutrality, as ASN are currently allowed to vote in regional head elections but prohibited from expressing political preferences publicly. This study aims to analyze the regulation of ASN voting rights in regional head elections, using normative legal research with a statute and case approach. It examines laws and regulations relevant to ASN neutrality and reviews cases of neutrality violations in regional elections. The findings reveal that ASN neutrality is regulated under Article 2 letter f of the Regional Election Law, emphasizing that ASN must remain impartial and avoid influence. Articles 119, 123, and 70 reinforce restrictions on political involvement by requiring resignation for those running for office. These regulations ensure legal certainty, efficiency, and justice by preventing power abuses stemming from personal interests. Strengthening these provisions is critical to uphold democratic integrity in regional elections.
