Authors: Sukuvaara Timo , Mäenpää Kari , Honkanen Hannu , Pikkarainen Ari , Hippi Marjo , Karsisto Virve
Published: November 2024

Accidents involving heavy road vehicles are often destructive, causing operational losses, human casualties, infrastructure losses, and negative environmental impacts. The risk is especially high in wintertime traffic. The Eureka Xecs SafeTrucks project (Heavy traffic safety improvements by advanced dynamics and road weather services) develops real-time vehicle-specific weather and safety services tailored to each vehicle, based on the vehicle’s own sensor-based observations combined with data from weather service systems and an analysis of the vehicle’s own dynamics. The services will also be analyzed by Digital Twin modeling in Hardware-in-the-Loop (HIL) and Driver-In-the-Loop (DIL) scenarios, in order to evaluate and refine them in a controlled environment. This paper focuses on operative fleet piloting, while the Digital Twin approach will be presented in future work. The pilot services are ultimately tested in a pilot system within operative heavy traffic. This paper presents the concept and architecture of the platform, with preliminary results of pilot services operation, alternative communication analysis, and system evaluation.
Mutation in Wzz(fepE) Linked to Altered O-Antigen Biosynthesis and Attenuated Virulence in Rough Salmonella Infantis Variant
Authors: Iduu Nneka Vivian , Kitchens Steven , Price Stuart B. , Wang Chengming
Published: November 2024

Salmonella enterica serovar Infantis has emerged as a prevalent foodborne pathogen in poultry with significant global health implications. This study investigates the molecular characteristics influencing virulence in a S. Infantis rough variant collected from a poultry farm in the USA. In this study, whole genome sequencing and comparative genomics were performed on smooth and rough poultry S. Infantis isolates, while chicken embryo lethality assay was conducted to assess their virulence. Comparative genomics between isolates was analyzed using Mauve pairwise Locally Collinear Blocks to measure the genetic conservation. Embryo survival rates between the isolates were compared using the Kaplan–Meier curves. High genomic conservation was observed between the two isolates, but a frameshift mutation was detected in the Wzz(fepE) gene of the rough variant, resulting in early protein truncation. The chicken embryo lethality assay showed that the lethality rate of the smooth strain was higher than that of the rough strain (p < 0.05). This study identifies a frameshift mutation in the Wzz(fepE) gene, leading to protein truncation, which may reduce bacterial virulence by impacting O-antigen biosynthesis in the rough Salmonella Infantis variant. These findings deepen our understanding of S. Infantis pathogenesis and suggest that targeting the Wzz(fepE) gene or related pathways could be a promising strategy for developing effective vaccines and therapeutic interventions.
Digital Applications for Videoterminal-Associated Dry Eye Disease
Authors: Romeo Maria Angela , Coco Giulia , Taloni Andrea , Carnovale-Scalzo Giovanna , Scorcia Vincenzo , Giannaccare Giuseppe
Published: November 2024

Dry eye disease (DED) has become increasingly prevalent in the digital era, largely due to prolonged screen exposure. The excessive use of digital devices contributes to inappropriate blink frequency and dynamics, leading to ocular surface dryness and discomfort. Additionally, digital screen use has broader implications for systemic health, including visual strain, headaches, and disrupted circadian rhythms caused by blue light exposure. Previous studies have shown that prolonged screen time correlates with altered blink frequency and increased symptom severity in DED patients, exacerbating the imbalance in tear film production and evaporation. Blinking dynamics, particularly blink rate and completeness, are crucial in maintaining ocular surface moisture. Incomplete blinking impairs meibomian gland function, reducing lipid secretion, which is essential for preventing tear evaporation. Raising patient awareness through educational material, ergonomic adjustments, and blinking exercises has been shown to mitigate these effects. Digital tools that provide targeted educational interventions can be particularly effective in improving blink dynamics and overall ocular comfort. This study evaluates the efficacy of digital applications in optimizing blinking dynamics and enhancing tear film stability. The findings suggest that these innovations improve patient outcomes by encouraging healthier eye care practices. However, further research is needed to assess their long-term impact across diverse populations.

Authors: Wong Angel YS , Warren-Gash Charlotte , Bhaskaran Krishnan , Leyrat Clemence , Banerjee Amitava , Smeeth Liam , Douglas Ian
Published: November 2024

Background:Direct oral anticoagulants (DOACs) are commonly co-prescribed with statins. Although biologically plausible, whether there is a drug interaction between DOACs and atorvastatin/simvastatin is unclear. Aim:To investigate the association between co-prescribed DOACs and atorvastatin/simvastatin and bleeding, cardiovascular disease and mortality. Design and Setting:Clinical Practice Research Datalink Aurum(1/1/2011-31/12/2019). Method: We used a cohort design to estimate hazard ratios for clinically relevant pharmacological interaction safety outcomes (intracranial bleeding, gastrointestinal bleeding, other bleeding) comparing DOACs+atorvastatin/simvastatin with DOACs+other statins (fluvastatin, pravastatin and rosuvastatin which are not anticipated to interact with DOACs). Effectiveness outcomes (ischaemic stroke, myocardial infarction, venous thromboembolism, cardiovascular mortality, and all-cause mortality) were also included. A case-crossover design comparing odds of exposure to different drug initiation patterns in hazard window versus referent window within an individual was also conducted. Results:Of 397,459 DOAC users, we selected 70,318 people co-prescribed atorvastatin, and 38,724 co-prescribed simvastatin. The cohort analysis showed no difference in risk of all outcomes comparing DOACs+atorvastatin/simvastatin versus DOACs+other statins. In case-crossover analysis, ORs for other bleeding (OR:4.04; 99%CI:3.07–5.31) amongst those initiating DOACs while taking atorvastatin, and the ORs for gastrointestinal bleeding (OR:5.16; 99%CI:3.66–7.28) and other bleeding (OR:5.12; 99%CI:3.61–7.26) amongst those initiating DOACs while taking simvastatin were greater than those initiating DOAC monotherapy. Similar patterns were also observed for cardiovascular mortality and all-cause mortality. Conclusion:This study shows no evidence of interaction between DOACs and atorvastatin/simvastatin. However, people starting a DOAC whilst taking atorvastatin/simvastatin, were at high risk of bleeding and mortality, likely due to temporal clinical vulnerability.

Published: November 2024

Background: Identifying effective factors in the success rate of assisted reproductive technologies can be a promising step. This study examined the effects of changes in endometrial thickness and vascularity following administration of progesterone on pregnancy rates in women who underwent frozen-thawed euploid blastocyst transfer cycles. Methods: Overall, 200 infertile women underwent in vitro fertilization (IVF) to treat infertility. All patients received estrogen, and 10 days after the start of estrogen, if the thickness of the endometrium was more than 7 mm, progesterone was started for the patient. A transvaginal ultrasound was performed on the day of starting progesterone, and the thickness of the endometrium and endometrial view, presence of blood flow in zone III of the endometrium, and uterine artery pulsed Doppler indices were evaluated. The second time of ultrasound was performed 3 days after the initiation of progesterone, and the same parameters were checked on the day of transfer of the cleavage embryo. Eight weeks after the transfer of the embryo, a beta-human chorionic gonadotropin test and ultrasound were conducted to check the pregnancy and the presence of a fetal heartbeat. Results: Endometrial thickness significantly decreased after progesterone administration, but it was considerably thicker in the pregnant group than in the non-pregnant. After receiving progesterone therapy, noticeable differences were observed in the appearance of the endometrium and the distribution of vascularity in zone III across the groups. Conclusion: Endometrial thickness, view, and zone III vascularity were associated with IVF success rate, but there were no significant changes regarding Doppler indices. Whatever change in Doppler indices that occurs after progesterone administration has no significant effect on embryo transfer success rate.

The paper gives a brief review of publications on the application of mathematical modeling
methods in pension provision. Regarding the application of the Heston-Hull-White model in pension fund manage ment, specifi cally, we examine: the description of pension fund returns in Spain and Great Britain using an autoregressive model and neural network; the model of pension plan participants in the Slovak Republic; the problem of optimal management of defi ned contribution pension funds; the problem of optimal investment of a pension scheme participant facing stochastic infl ation; the nonlinear optimization model for the Italian defi ned contribution pension system. The paper develops two versions of the Leontief piecewise linear function for the total annual funding of the Russian Social Fund’s Irkutsk Oblast branch: the ordinary version and the version with optimal transformations of the independent variables. Both versions are characterized by
acceptable accuracy. Their triggering vectors indicate that the factor determining the dynamics of the output variable is the number of self-employed (payers of contributions for themselves).

The research analyzes the working architecture for a neural network decoding algorithm based
on belief propagation. It is found that the weight distribution and an effi cient computational graph determine the number of trainable parameters and computations in the neural network. The weight distribution involves calculating the weighted sum of the output signals of the neurons of a layer, multiplied by the corresponding weights, and adding the biases. The data region extraction method involves applying a nonlinear activation function to the output signals of neurons. After several iterations of local decoding, the algorithm calculates the loss value using the mean square error loss function. The simulation results indicated that using an approach similar to the neural network Belief Propagation (BP) algorithm improved the performance compared to the standard decoder built using the standard BP algorithm. A robust neural network-based decoding scheme for wireless communication systems is proposed. This recurrent neural network architecture, based on gating and weight distribution algorithms, is designed to perform belief propagation decoding without prior knowledge of the coding scheme.
Tiempo libre, cuerpo y educación en Zumba®
Authors:   , Scarlato García Inés
Published: November 2024

Esta tesis investiga las características centrales del tiempo libre en las sociedades capitalistas contemporáneas, como vía para contribuir a una crítica del presente. Este objetivo se establece desde las preocupaciones del campo de la educación, en particular de la Educación Física, proponiendo para ello el estudio de la gimnasia patentada Zumba®. El abordaje de esta práctica corporal se establece, por un lado, desde una perspectiva crítica para el estudio del tiempo libre, que será elaborada a través del diálogo con las principales teorías que en la actualidad hacen de éste su objeto de estudio. Y, por el otro, inscribiendo a Zumba® en el contexto de las transformaciones culturales del capitalismo contemporáneo, a fin de dar cuenta cómo dichas transformaciones sociales y culturales se sedimentan en este objeto. Se trabaja a partir de la articulación de metodologías diversas que incluyen la discusión bibliográfica, así como un trabajo de campo desarrollado con observaciones y entrevistas (a practicantes e instructoras) en torno a dos ámbitos con clases regulares de Zumba® y tres eventos masterclass desarrollados en Montevideo, a lo cual se agrega el análisis de publicaciones realizadas por la empresa. Entre los principales resultados se destacan: a) la emergencia disruptiva de Zumba® en el campo de la gimnasia y, particularmente del fitness, al punto de generar una ruptura/quiebre para con el dominio racional del cuerpo (afín a la gimnasia decimonónica), a la vez que atenta contra las posibilidades de una formación; b) la expansión de este producto para el consumo universal, a través de la integración de manifestaciones culturales diversas que suponen, al mismo tiempo, su homogeneización a través del estilo Zumba®; c) la organización de cápsulas de repetición dispersa, capaces de asegurar una diversión que posibilita acceder a la felicidad subjetiva, desenvolviendo un mecanismo que permite realizar lo postergado y sobrellevar la existencia en una temporalidad marcada por el presentismo; d) la puesta en funcionamiento de una pedagogía para la formación de formadores centrada en la figura del emprendedor, la cual establece una rígida oposición respecto del “mediocre”, estableciendo una “educación” que se sirve, paradójicamente, del olvido como posibilidad de apropiación de la novedad; e) la organización de formas de trabajo voluntario y autogestionado, que combinan fines individuales y altruistas, al mismo tiempo que se sostienen situaciones de informalidad, incertidumbre y precariedad laboral.

Authors: Macpepple Eunice D. , Egwuonwu Celestine C , Tom Cyprian N
Published: November 2024

In this research, a solid waste
management performance model was developed for
Owerri municipality. This was necessitated by the
existing poor waste management and service
provision in the area. The present system
performance and ideal real time model expectations
were investigated. The model was developed in line
with the established balance score card (BSC)
concept using MATLAB 2021a software. 30
performance indicators were identified from 4
component objectives enshrined in globally
accepted solid waste management systems and
processes, namely, customer perspective (CP),
internal process perspective (IPP), learning and
growth perspective (LGP) and financial perspective
(FP). These indicators were used as building blocks
for developing the model. Indicators for physical
parameters included leachate temperature, total
dissolved solids (TDS) and total suspended solids
(TSS). Leachate analysis confirmed the presence of
high concentrations of TDS (6723kg/m), TSS
(5731kg/m), total ammonia (186kg/m), and high
BOD (137kg/m) and COD (614kg/m) levels,
respectively at the active official dumpsite in the
study area. The corresponding model results showed
an overall SWM performance of 37.5%. The FP
scored 0%. Outcome showed that specific areas that
needed improvement were in the areas of waste
collection coverage, final disposal, environmental
endurance, inclusivity, financial sustainability and
recycling and treatment facilities. The study also
disclosed a systematic method for assessment of
performance of the integrated solid waste
management system (ISWMS) in the municipalities.
Investigation on Hygroscopic Properties of Laminated Composite Bamboo
Authors: Sujita Sujita , Sutanto Rudy
Published: November 2024

The purpose of this study was to
investigate the water absorption of laminated
compositebamboo. Bamboo fibers as
reinforcements for laminate composites came from
apus bamboo ((Gigantochloaapus/GA) and wulung
bamboo (Gigantochloaatroviolacea/GV). The
hygroscopic properties of bamboo in the base,
middle, and edge sections were compared and
analyzed using the dynamic vapor absorption
(DVS) method. The results were analyzed using the
parallel exponential kinetics (PEK) model. The
results showed that the hygroscopic properties of
the fibers between the base, middle, and edge. The
percentage of water absorption of apus bamboo
laminate composites is higher than that of wulung
bamboo laminate composites.The percentage of
water absorption of the apus bamboo laminate
composite (GA) is the largest at 3.64%, the wulung
bamboo laminate composite (GV) is the largest at
3.01, each under the condition of square root of
time 700 sec. Bamboo fibre belongs to cellulose
fibre. Its water absorption properties are higher
than fibreglass. High water absorption is a major
drawback of cellulose fibres, as the main cause of
degradation in the mechanical performance of the
composite. Cellulose fibres absorb moisture due to
their hydrophilic nature caused by the presence of
multiple H-bonds (-OH groups) between the cell
wall macromolecules in the fibre

A study entitled ‘Assessment on farmers’ perception and adoption of kiwi fruit in Sandakpur Rural Municipality
of Ilam was conducted to explore the perceptions and adoption of kiwi cultivation among farmers .The study
comprised 80 participants, evenly divided between 40 kiwi growers and 40 non-kiwi growers, and incorporated
two FGDs and two KIIs. The simple random sampling technique was used for sampling, and MS Excel and IBM
SPSS 26 for data analysis. Farmers in Sandakpur generally had a positive view of kiwi cultivation,
acknowledging its economic potential. Key factors influencing kiwi adoption included access to information,
training, financial resources, land availability, agricultural extension services, and technical support (p-value <
0.05). However, age and gender did not significantly contribute (p-value > 0.05). Problem ranking identified
challenges for kiwi growers. The most significant problem reported was inadequacy of storage, with an index
value of 0.89, making it the top-ranked issue for kiwi growers. The challenge of insufficient kiwi product and
processing factories ranked second with an index value of 0.75. Additionally, the unavailability of good quality
of seedlings was identified as the third-ranked problem, with an index value of 0.565 followed by inadequate
market intelligence. Finally, insect pest and disease infestation was ranked fifth, with an index value of 0.33.In
conclusion, this thesis underscores the importance of providing farmers with the necessary knowledge,
resources, and support to fully embrace kiwi cultivation as a sustainable and profitable agricultural endeavor.

The Escola Universitària Formatic Barcelona (EUFB) is a prestigious university institution located in the center of Barcelona in a listed historical building at Passeig de Gràcia avenue nº 66. This article investigates the origins and characteristics of the Casa Vidua Marfà, the current headquarters of the EUFB, retracing its history and that of the families who made it a reality. A period that goes from the 18th century to the beginning of the 20th century at a time when Catalan traders known as ‘Indians’ left their mark on the architecture, gastronomy and traditions of Catalonia. The analysis of Casa Vidua Marfà constitutes an exponent of that period when Catalan merchants tended to set sail when they were young and poor and go to the Americas, especially to Cuba and Puerto Rico, in search of new job opportunities. Back from their journey abroad, if successful, ‘Indians’ continued to invest in businesses and industries throughout Catalonia and, in this particular case, contributing to the urbanization process in the center of Barcelona.
Enhancing the Assessment and Optimization of Critical Elements through Fuzzy Aggregation: A Methodological Framework for Evaluating E-Services

This paper addresses the challenge of accurately measuring the E-Service Quality (ESQ) of app-based travel portals by using a structured framework of linguistic and mathematical variables. The approach allows for the evaluation and improvement of key performance indicators through fuzzy aggregation, providing a quantitative understanding of service quality in dynamic environments. The proposed method evaluates the system's state by analysing the parametric values of its sub components, which define the system at any given time. We identify three primary factors crucial for assessing ESQ: the state change required relative to the current system state and the relative significance of tasks. The paper elaborates on three critical variables: the significance of a factor (Si), its observed level (Li), and the contribution of the factor (Delta i) towards ESQ. These variables are assessed using fuzzy aggregation, converting linguistic inputs into crisp numeric outputs, thereby quantifying the impact of each factor. The methodology provides a structured and flexible approach to gauge and improve the performance of travel portals by focusing on key performance indicators and their respective weights.

Operation of interconnected power system network involves connection of many generators. It is required that all the generators must remain synchronized at all times when operating within their rated capacity. Unabated continuous grow in system loading may lead to machine running out of synchronism. This paper assessed steady state stability of power system employing synchronous power coefficient (SPC) using the Nigerian 28-bus, system. Variation in system loading will result in variation of output power for each generator. SPC is the criterion that determines whether generators remain in synchronism whenever there is a variation in load using the kinetic energy stored in its rotating masses. It is a measure of safety of operation of power system steady state stability (SSS). To determine the SPC, power flow was carried out using Newton-Ralphson method with varying loads. The reduced admittance matrix (RAM) for 𝑌􀯀􀯀 was formulated from the bus admittance matrix. The voltages behind steady state reactance of the generators were determined and used in conjunction with RAM to determine power transfer between generator-generator. Power flow was repeated with variation of loads in step of 30%. SPC was simulated with consideration of 130%, 160% and 190% of active load. Utilizing MATLAB programming language, the results revealed that the system is stable for 130% and 160% load variation and unstable when 190% of rated load is suddenly applied to the network. This work is a pointer to the percentage of sudden load that can be connected without the system running out of synchronism
Proportional, Integral and Derivative Control Strategy of Triethylene Glycol Recovery Regenerator for Optimum Natural Gas Dehydration Process
Authors: Wosu C. O.
Published: November 2024

The research considered the application of the conservation principle of mass and energy balance in the development of the dynamic model of a triethylene glycol (TEG) recovery regenerator. The mass and energy balance was performed at the feed point (inlet) and the bottom (outlet) of the regenerator. The natural gas TEG dehydration plant was designed using HYSYS while the control analysis was performed at the feed point and bottom (reboiler) of the regenerator. The behaviour of the process was analyzed in terms of an open loop with disturbance and a closed loop for both manual and automated proportional, integral and derivative (PID) control configurations using Simulink. The effect of the process variable (temperature) was measured using a thermocouple configured in the closed-loop system. The result of process behaviour for an open loop system with a disturbance at the feed point, and reboiler section as a function of temperature with time indicates a high level of process instability. While the use of manual tuning of various PID controllers. Parameters or gains in the closed loop system for temperature control at the feed point and reboiler section of the regenerator also showed a high degree of system or process instability as indicated in the temperature and time profile behaviour, where the system failed to attain its stability even at 10seconds. However, the use of automated controller gains of (1.438,- 2.733, and 0.1864) and (0.1773, 0.1665, and 0.04408) for 𝐾􀯉 , 𝐾􀯂 𝑎𝑛𝑑 𝐾􀮽 at the feed point and reboiler section of the regenerator showed that the system attained its stability at 10seconds and 2.5seconds after a tuning of 402.5 times and 205.3 times respectively and at a set point temperature of 80°c for the regenerator feed point and 2040C for the regenerator reboiler section. The above analysis clearly shows that for optimum TEG recovery during the dehydration process, the use of an automated PID controller gives a better performance characteristic compared to manual tuning and ensures the system or process attains its stability within the shortest possible time.

In this study, an attempt was made in designing and fabricating a portable milling machine from locally sourced raw materials which can be utilized by low income rural dwellers not connected to the electricity grid to achieve size reduction of grains such as maize, sorghum and other agricultural materials. The machine seeks to improve on some the shortfalls observed in previous designs of existing hammer mills currently in use. The size reduction was achieved with the aid of freely rotating hammers attached to a shaft. The prime mover employed for the machine was petrol engine. Detachable screens with various screen sizes were provided to achieve various particle sizes of milled samples. From the result of the preliminary investigation performed on the machine, it was seen that the machine performed satisfactorily with a maximum efficiency of 92 % and optimum throughput of 18.2 kg/hr.

Frictional properties of cast aluminium based silicon-copper-zinc (Al-Si-Cu-Zn) alloy were studied in and without DOT4 brake fluid environment using a standard ball on disk tribometer. Substrates were prepared by grinding and polishing to 0.2 m mirror-like, smooth and uniform surface. The examinations of the polished and worn surface morphologies and microstructural analysis were carried out using high resolution metallurgical microscope. Standard size 6 mm diameter alumina ball was rubbed on the cast Al-Si-Cu-Zn alloy specimens surface using different loads (1~10 N) at room temperature (25.00 °C) and atmospheric humidity of 50%. Increased normal force Fn loading initially gave a considerable decline in coefficient of friction (CoF) values for the dry and wet sliding conditions but latter, the CoF stabilized over wide time range for both contact situations. The CoF values reduced from average of u = 0.415 to 0.174 at 1 N; u = 0.4997 to 0.1689 at 5 N; and u = 0.82 to 0.193 at 10 N respectively during the dry and wet sliding contacts. The results showed that the alloy was resistant to wear under the two experimental conditions.
Youth Geographies: giovani e spazio pubblico. Una scoping review della letteratura geografica
Authors: Boccaletti Silvy
Published: November 2024

La ricerca geografica sta prestando sempre più attenzione ai giovani, considerati attori nell’utilizzo degli spazi pubblici. All’interno di questo quadro, nonostante le trasformazioni, corrosioni e privatizzazioni che hanno profondamente trasformato le città europee, gli spazi pubblici rivestono ancora un ruolo centrale nelle loro geografie quotidiane: luoghi in cui i giovani possono ritagliarsi degli spazi di creatività, di crescita e sviluppo personale. Allo stesso tempo gli spazi pubblici sono anche ambiti urbani dominati dall’influenza degli adulti, che possono imporre le modalità di utilizzo in modo egemonico, limitando la capacità dei giovani di agire, appropriarsi e re-immaginare questi spazi della città complessi, caratterizzati, nella loro forma comunemente intesa, da una diversità in termini di legittimità d’uso dei suoi fruitori, funzioni, durata e modalità di accesso. L’obiettivo di questo contributo – che si presenta in forma di scoping review, esaminando gli articoli pubblicati dal 2000 a oggi nelle più qualificate riviste scientifiche che si occupano di studi spaziali – è contribuire a future agende di ricerca sui giovani e lo spazio pubblico, un campo di ricerca che oggi, in un quadro politico internazionale che aspira a includere sempre più le nuove generazioni nello sviluppo delle società del futuro, risulta cruciale iniziare a sistematizzare. In particolare, l’analisi si propone di mettere in risalto le fasce d’età dei partecipanti coinvolti dagli studiosi, i metodi di indagine e i temi più affrontati in questo campo di studi. Il quadro che emerge impone una riflessione critica nell’ambito della comunità scientifica sulla necessità di criteri e orientamenti più espliciti e critici che aiutino a decodificare con più forza la complessità che porta con sé l’indagine in questo campo.
Italo Calvino: il primo geografo del nuovo millennio
Authors: De Vecchis Gino
Published: November 2024

Il contributo intende cogliere nella vasta e multiforme produzione letteraria di Italo Calvino, del quale nel 2023 si è celebrato il centenario della nascita, gli aspetti che più di altri hanno suscitato interesse in ambito geografico. La natura enciclopedica della sua opera lo ha portato, infatti, a scrivere pregevoli testi dove saggistica – rivolta a tanti e diversificati saperi scientifici (geografici compresi) – e narrazione si contaminano felicemente. I criteri e i procedimenti di lettura, osservazione e racconto del mondo, posti in essere da Calvino, presentano una chiara originalità, che deriva da una suggestiva combinazione tra razionalità (scienza) e immaginazione (poesia), dalla ricchezza delle sue visioni di spazio, legate non soltanto a esperienze vissute, ma anche a elaborazioni di incomparabile fantasia. Il contributo si sofferma in particolare sul concetto di paesaggio, sulle relazioni tra società e natura e sul senso di abitare le città. Ancora oggi lo scrittore ligure è in grado di proporre alla comunità dei geografi suggestioni e mezzi per orientarsi nelle attuali coordinate spaziotemporali, offrendo occasioni preziose di approfondimento per descrivere e interpretare la complessità del mondo.
Colombo e Verrazzano. Strategie denominative a confronto
Authors: Cassi Laura
Published: November 2024

Le strategie denominative di Cristoforo Colombo e Giovanni da Verrazzano seguono canoni simili: nomi che esprimono deferenza religiosa, nomi in omaggio ai finanziatori e protettori delle loro imprese, nomi suggeriti dalle caratteristiche dei luoghi, nomi legati alla sfera personale, e così via. In particolare quelli di Colombo mirano a sottolineare il possesso per la Corona spagnola, in quelli del Verrazzano spiccano richiami al paesaggio fiorentino. Lo studio analizza analogie e differenze, mettendo in evidenza il potere simbolico del nominare come atto di scoperta e appropriazione.
