The Frade field, located in Campos Basin, offshore Brazil, is currently being developed using the latest advancements in reservoir mapping-while-drilling (RMWD) systems to aid horizontal well placement and enhance reservoir characterization. The technologies implemented include the high-definition (HD-RMWD), and the three-dimensional (3D-RMWD) systems, which convert ultra-deep electromagnetic measurements into a map of the resistivity profile around the borehole.

The HD-RMWD provides multilayer detection using a 1D deterministic parametric inversion engine that provides a detailed 2D resistivity map along the well trajectory, resulting in enhanced capabilities for geosteering and reservoir characterization. This system was implemented in the horizontal wells drilled in Frade since 2022. For landing, an actual vertical detection of around 20 m TVD has helped to set casing in the desired target, identifying the presence of shallower layers—that could result in a poor landing—when present. Within the reservoir, the radial depth of detection achieved with a two-receiver configuration was on the order of 30 m TVD, enough to map top and base of sandstone geobodies while identifying the occurrence and dipping of multiple thin beds.

The 3D-RMWD extends the application of this type of technology to the most complex reservoir settings and enables azimuthal geosteering. A set of new measurements—the full 360° electromagnetic tensor—is acquired and transmitted in real time using a new data compression algorithm, and then converted into 3D resistivity volumes derived from a cloud-based 2D transverse inversion technique. Results from the use of the 3D-RMWD technology in Frade—first case in Brazil's offshore operation—showed the 3D mapping capability of different geobodies in a complex geological environment. It also showed how reservoir properties were changing transversally along the well trajectory.

A previous-generation RMWD system was used in offshore Brazil for 13 years, and this paper presents the experience gained from using the latest developments. The HD-RMWD system represents a significant advance by providing a finer resistivity map around the borehole, while the 3D-RMWD technology opens a whole new area of application, especially for complex reservoir characterization and provides means for azimuthal geosteering, which is currently an avoided practice.

Published: April 2023

In 2009, the Vito field was discovered in more than 4,000 ft of water approximately 150 miles offshore from New Orleans, Louisiana. The project produces from reservoirs nearly 30,000 feet below sea level. This paper outlines the approach taken to develop the Vito facilities operating model (Operating Model) and prepare for start-up and ramp-up. This paper is part of a Vito Project series at OTC 2023, and the other papers are listed in the references.

In 2015 the project faced significant financial hurdles and went through a refresh of the concept design to reduce cost and simplify while maintaining safety as a top priority. This re-design resulted in reduced redundancy and operational flexibility including reducing host personnel on board (POB) capacity to 60 personnel. To prepare to start-up and operate the facility with this simplified design, a proactive approach was adopted across four key areas: Operating Model, maintenance strategy, digital building blocks, and start-up ramp-up (SURU) planning.

An Operating Model was developed to enable efficient execution of maintenance and operations activities with the reduced POB. This model leverages multiskilling of onsite personnel and enabling digital technologies. The limited POB necessitated development of a maintenance strategy that is both lean and comprehensive with high utilization of the base crew. With local performance standards as the foundation of the strategy, a Reliability Centered Maintenance (RCM) study was performed to validate and further optimize the defined strategy, which relies heavily on asst specific maintenance tasks and onshore sparing due to minimal redundancy and space on host for spares.

Digital Twin technology has been leveraged to create a virtual mirror image of the Vito facility that is a central repository of equipment data and documentation. This enables virtual planning of work which reduces POB needs by providing the ability to perform walkdowns, take measurements and identify access issues without being on site. Augmented reality technology supplements this by streaming the viewpoint of offshore staff directly to onshore teams to perform troubleshooting, diagnose issues, and inspect without requiring physical presence.

To manage well start-up and to optimize long term recovery, a start-up ramp-up model was implemented with a focus on proactive actions to optimize start-up. This led to long term lease of onshore caverns to eliminate requirements for temporary unloading equipment during start-up. A phased commissioning and start-up plan was developed with gas buyback brought on ahead of well start-up to pressure up vessels and commission compressors. Additionally, a real time simulator was built to test procedures, train personnel and walkthrough the start-up plan.
Vito Project: Hull / Mooring Design & Platform Installation

Published: April 2023

In 2009, the Vito field was discovered in more than 4,000 ft of water approximately 150 miles offshore from New Orleans, Louisiana. The project produces from reservoirs nearly 30,000 feet below sea level. This paper provides an overview of the Hull & Mooring system, executing a minimum technical scope to produce a simplistic design. This paper is part of a Vito Project series at OTC 2023, and the other papers are listed in the references.

The original Vito project execution strategy was to replicate the Shell mega-project of Appomattox. As the industry and market began to change in 2015, the project faced significant financial hurdles, and the project team decided to refresh the design concept to reduce cost and simplify. The team regrouped to propose a smaller semi-submersible Floating Production System (FPS) with a simplistic mooring design. The Topsides was designed to be lifted as a single module, with a payload of less than 10,000 st to enable competitive tendering process.

The redesigned FPS concept was moored with 12 taut, chain – polyester – chain mooring line system utilizing an in-line mooring tensioner, removing the traditional mechanically complicated and space demanding "on-vessel" winch systems. Vito employed a passive hull system, with all ballasting occurring over the top without hull penetrations. There were no pump rooms within the hull as equipment is accessed from top of column, removing the need for regular hull access to maintain equipment. The hull compartmentation also followed a simple approach, containing only 12 ballast tanks to reduce fabrication cost. The hull design also included simplified ring stiffening for columns which eliminated the traditional orthogonally stiffened systems. Additionally, the structure utilized an upper column frame structure to support the topsides deck and served as a bracing for supporting columns at the top for squeeze-pry loads and bracing for supporting columns during dry tow. The simplification of the stiffening system and topsides deck support design reduced interfaces between hull and topsides and also opened up options for fabrication of topsides and hull.

Key challenges included developing installation methods without traditional FPS mooring chain jacks and increasing installation options by not requiring a large installation derrick barge and enabling use of common anchor handler vessels. The project experienced fabrication delays due to COVID-19, which required creative solutions transporting the FPS from Singapore to the Gulf of Mexico. The design team enabled the use of various heavy transportation vessels (HTV), ultimately settling on a smaller HTV modified with four 25 ft outriggers.
Casing Exit to Casing Entry - A Novel Concept for the Abandonment Process in Intersect Applications
Authors: Emelander Tom , Willis Matthew
Published: April 2023

The number of mature wells worldwide requiring abandonment intervention is rapidly gaining exposure again as the industry recovers. Current access to the completion, using straightforward methods of barriers to satisfy regulatory standards, is the primary means of completing the life cycle of a well. Other methods require an intersect process into the existing wellbore for the abandonment to be considered compliant. Using whipstocks to assist with the intersect can reduce time vs. conventional methods.

Traditional methods of intersecting wells involve drilling or milling into the existing wellbore using directional assemblies, usually after a sidetrack operation up hole. This process of trying to breach into the existing well can be problematic and result in multiple unsuccessful attempts, driving up operational spend. Rather than leaving an intersect to chance, a whipstock can be used as a diverter to increase the likelihood of success while also controlling depth and direction more accurately. Once run into the well and anchored, the whipstock also acts as a re-entry guide for intervention and abandonment operations.

An in-depth analysis of a recent abandonment operation, where both directional assemblies and eventually a whipstock was used to intersect existing casing for abandonment and to highlight the advantages and pain points associated with both methods. Through detailed preplanning, intensive logging, wellbore preparation, and prior experience, the whipstock operation was successful relative to prior attempts with conventional methods. The intersect and following abandonment process were not completed without lessons learned. Hole conditions, an up-hole casing exit junction, and custom cement blends were a few of the areas of focus for future improvement on efficiency. Even with operational challenges, the whipstock operation reduced time spent intersecting the well.

This paper shows that whipstocks are a viable option to reduce time spent intersecting wells for abandonment purposes. This case history provides the industry an opportunity to replicate this success in similar applications.
Case Study: Use of Vessel Motion Based Criteria to Establish Operational Window in Critical Operations

Published: April 2023

In this paper, a methodology is proposed to use FPSO Fluminense motion-based criteria to establish the operational window for the disconnection and safe removal of a flexible riser with structural damages in parts of the tensile armour wires. A global model was established in Orcaflex to describe the FPSO and flexible riser responses considering two sea states (Hs = 2.0 and 2.5 m / Tp = 12.5s) and different headings from 0° to 45°. The results are then post-processed to calculate the statistics of top tension for 20-minutes time intervals and assess its correlation with FPSO motion (Heave, Pitch, Roll and Heave Rate). Finally, limit values for FPSO motion could be calculated using a high-level confidence interval in the regression analysis and comparing with top tension allowable limit considering the broken wires. A strong correlation was found between FPSO movements and top tension on the riser to be removed for all variables except for roll amplitude. Therefore, it was decided not to establish a roll limit in this case, but to use the roll measurements as an indication of the actual heading relative to incoming waves. A linear regression model and a confidence interval were calculated considering 99.9% of confidence to calculate the upper motion limit that would provide top tensions greater than the allowable limit. The calculated limit was then compared to the data measured by onboard MRU to support risk assessment in real-time. Based on historical data, the operational window could be improved by 7% using motion limit criteria and only 2% of historical data provided a rigid no-go (all limits reached).
Effective Power Transmission from Offshore Wind Farms
Authors: Iversen Øyvind , Doedens Espen
Published: April 2023

To cover future requirements for the offshore wind industry, which demands new innovative technology, a system approach to the transmission / export system has been investigated. Testing, modelling and manufacturing have been carried out to scale cable technology to higher voltage levels. This includes material testing, sample testing, and ultimately the manufacturing of full-scale cable system prototypes. Such prototypes comprise a multitude of different cable accessories, which together have been subjected to rigorous type-and pre-qualification tests per the present industry standards.

Subsea HVAC transmission systems are well known, but exhibit different types of transmission losses, especially pronounced for high voltage and longer lengths. Such losses can to some extent be minimized through cable design and a tailored phase compensation system. A recently qualified 145 kV AC system is currently undergoing testing in order to scale this for higher voltages. Subsea HVDC cable systems exhibit far fewer transmission loss types but do require converter stations compromising complex electronics at both ends. Such converters are both costly, large, and add a link length independent loss penalty. A recently qualified 525 kV extruded HVDC system, now capable of operating at higher rated temperature, is a new enabler for large bulk power flow at 1.2 GW per single pole and beyond.

Thereby, the technology has been scaled from dry 145 kV cable system to 245 kV AC or, from static 320 kV DC systems to a robust 525 kV DC offshore wind system. Based on successful test results, further prototypes are also to be manufactured in 2023.

Floating offshore wind parks currently only exist at lower power levels and voltages. This paper presents how the required high power systems can be enabled using novel technology combined with technology proven for other use.
Serial Production of Floating Wind Concrete Foundations

Published: April 2023

Floating foundations in concrete for wind turbines offshore is a concept which up till now have limited use in full scale applications. Currently, the Hywind Tampen project is the only executed project with concrete substructures and multiple structures in a commercial setting. Serial producing such foundations require new ways of thinking, modified methods and re-thinking of conventional design and construction processes. Results presented highlights the differences compared to conventional construction and points towards future developments and improvements using the Hywind Tampen project as a basis.

Construction of spar type substructures requires a combination of partly construction onshore/in dry dock and partly construction in a deepwater site and the concept, design and methods must accommodate the method of construction. For serial production material flow, progress and logistics becomes vital.

The serial production developed and used for the fabrication of Hywind Tampen concrete substructures proved to be a success, but we need to take into consideration that is a small-scale production compared with large offshore wind developments. The use of slipforming technique is an efficient and robust method for constructing watertight hulls and planning and adoption of this technique for serial production has been done successfully. Concrete substructures have been used for the offshore oil & gas fields since late 1960's and the knowledge and experience from design and execution methods has been implemented in offshore wind in parallel with developments required for a new industry and serial production.

Further development of floating substructures for offshore wind relies on contractors being able to fabricate fast, cost-competive and reliable foundations in a safe manner and within quality requirements for offshore structures. The Hywind Tampen project represent an international milestone in this respect, being first of its kind project within floating wind. There are multiple floating wind concepts on the marked but there is only one completed project worldwide where learnings and experience can be utilized for future developments, Hywind Tampen.
Eemshaven LNG - Repurposing an FSRU Built for Tropical Conditions to Operate in the North Sea

Published: April 2023

In 2017, Exmar has taken delivery of an FSRU which was intended to operate in Bangladesh to provide the country up to 600 MMSCFD of natural gas. The FSRU was purpose-built with a shallow draft to allow it to be moored in a river estuary. The project in Bangladesh never materialized and the FSRU ended up in lay-up in Singapore.

With the energy crisis unfolding early 2022 several countries in Europe urgently started investigating the possibilities to bring FSRUs to Europe to ensure the security of natural gas supplies and in order to have a back-up for the decreasing natural gas flow from Russia. It was proposed to mobilize our FSRU from Singapore and eventually a 5-year contract with Gasunie was signed. This deal made it possible to operate the FSRU at the EemsEnergy Terminal in The Netherlands.

For the FSRU to operate safely and efficiently at the new terminal, several modifications needed to be applied in order to adapt the FSRU to the new, colder environment. First and foremost, the regasification system needed to be provided with warm heating water. As per the original design, the FSRU regasification system needs seawater of at least 15 °C in order to avoid freezing in the LNG vaporizers. A closed loop heating water system was not foreseen for heating the water which is used to vaporize the LNG. Several options have been investigated and together with the Client, it was decided to use heat from shore as input for vaporizing the LNG.

The FSRU layout was also found incompatible with terminal layout and changes were required on the main piping system and on the mooring system. Within a couple of months time the mooring design was revisited, the main piping layout was modified to ensure the FSRU could fit the terminal and could stay safely moored in the new metocean environment. After the FSRU was mobilized from Singapore it went straight into the conversion yard in the Netherlands. Within a period of 2 months all changes were implemented and the FSRU could be deployed on time to supply LNG to The Netherlands.

This project demonstrates that our FSRU concept is flexible and can be redeployed quickly to other sites when market conditions change. Thanks to our in-house engineering and operational capabilities, we could upgrade the FSRU design in a short time, matching the very demanding project timeline.

Onboard Safety Solutions for VTOL UAS Operations
Authors:   Elektroniksystem-und Logistik GmbH (ESG), Banas Jacquelyn , Cords Andreas , Mehling Tim , Paul Tobias , Vyshnevskyy Matthias
Published: April 2023

In terms of safety, particularly challenging aspects of UAS operations include collision avoidance, managing operator workload and situational awareness, and ensuring the safety of personnel nearby. New European air safety rules introduced three UAS categories based on vehicle size and defined the SORA process as an initial framework for guiding designers and operators through risk assessment, in order to ensure an equivalent level of safety to manned systems. Risk mitigation systems reduce certification and operational requirements determined within the SORA process; therefore, the addition of onboard safety systems could enable the inclusion of larger uncertified UAVs into increasingly-sensitive missions. This paper evaluates three onboard safety solutions currently under development at ESG: a parachute-based UAV rescue system, a geofencing/geocaging system, and an airborne sense-and-avoid system. The three systems were first evaluated analytically in terms of their impact on the resulting SORA, given each system's reliability and type of risk mitigation. The SRDS was further evaluated via ground and flight tests, while future tests are planned for the other systems as their designs develop. Estimates for system-level safety factors and resulting operational considerations were derived for each design, offering perspective regarding the outlook for such onboard safety systems in mitigating failures up to the "major" level.
Optimal Trajectory Generation for Transitioning Quadrotor Biplane Tailsitter using Differential Flatness
Authors:   Rensselaer Polytechnic Institute, McIntosh Kristoff ,   DEVCOM Army Research Lab, Reddinger Jean , Mishra Sandipan , Zhao Di
Published: April 2023

This paper presents the development of an optimization-based trajectory planner for the autonomous transition of a quadrotor biplane tailsitter (QRBP) between the flight modes of hover to forward flight and forward flight to hover. The trajectory planner is formulated as an optimization problem with an embedded dynamic model of the QRBP, vehicle design constraints (e.g. power), physical constraints (e.g. stall) and initial/terminal states for the transition. A differentially flat reformulation is employed to reduce the computational cost of the trajectory planner for on-board mission planning. The solution of this problem yields time-optimal state and input trajectories for transition. Using this trajectory planner, we generate trajectories for various transition flight missions (from hover to forward flight and vice versa) under various constraints. Further, we demonstrate how the proposed algorithm can also be used to assess the agility of a vehicle in terms of minimum space required to perform a specific maneuver or transition, given physical design constraints (such as maximum power). Finally, we demonstrate trajectory tracking on a high fidelity simulation of a QRBP with a cascaded dynamic-inversion based controller with a control blending strategy between the quadcopter and forward-flight control modes, for hover to forward flight.

The Penn State Autonomous Robotics Competition Club has developed a platform tailored for use in Search and Rescue missions to support first responders. The key design drivers included the capacity to carry a 10 lb LTE system to extend coverage for first responders on the ground, capability for long endurance flights, cost effectiveness, and ease of setup and operation for a solo operator. A coaxial octocopter with a hybrid power configuration was designed, verified in simulation, and flight tested. With an estimated operational endurance of over 3 hours and high levels of autonomy including obstacle avoidance and object detection, the proposed solution provides a versatile configuration capable of numerous applications including emergency operations.
An Assume-Guarantee Framework for Multiple-Obstacle Collision Avoidanc
Authors:   Rensselaer Polytechnic Institute, Nallan Kaushik , Julius A. , Mishra Sandipan
Published: April 2023

In this paper, an assume-guarantee reasoning approach is developed for obstacle avoidance in unmanned aerial vehicles (UAVs) in the presence of multiple obstacles in an obstacle field. This construct assumes certain properties of the environment and the vehicle to guarantee the safety and performance of the UAV (in this case, executing safe collision avoidance trajectories). In the presence of a single obstacle, the assumptions on the environment and the vehicle parameters are constructed such that the UAV can plan a safe trajectory once the obstacle is detected. The approach to guaranteeing safety in the presence of multiple obstacles requires enforcing additional assumptions which is done by constructing a region of influence (RoI) around each obstacle, whose size depends on the environment and the vehicle parameters. The safe combinations of these parameters (codified as contracts) are developed such that the RoIs in the obstacle field do not intersect. The aforementioned approach is then used to decompose the general multiple obstacle avoidance problem into a sequential single-obstacle avoidance problem by constructing an induction-based algorithm framework. The proposed methodology is validated by an illustrative example with minimum obstacle detection range, maximum allowed cruise velocity, maximum allowable agility as vehicle properties; and maximum obstacle size and minimum obstacle separation as environmental properties. Contract generation for specific scenarios and implementation of sequential avoidance on a 6-DoF quadcopter simulation are demonstrated. Finally, the effect of tracking error on the contract-based framework is discussed, along with a mechanism to incorporate this source of uncertainty into the contract.
The Use of Face Clues in Teaching a Second Language
Authors: Metcalf P.
Published: April 2023

The Face Clues programme arose when struggling to teach a severely hard-of-hearing child how to speak. It was then developed further to complement the conventional methods used by therapists in teaching speech production to clients who are hard-of-hearing and deaf When the Face Clues are used in combination with auditory, tactile and kinesthetic stimulation provided by the teacher, the result is clearer speech production, which preserves individual variations in pronunciation and dialect without compromising comprehension. The basic template for the Face Clues is kept constant throughout the entire series of face phonemes. The shape of the mouth and essential element symbols depicting what cannot be seen in the production of each phoneme, are included in each face diagram. The Face Clues are not language bound and have already been adapted into English, Afrikaans, French, Zulu, and Kikonza. They are used locally and overseas in therapy with clients who present with different speech communication difficulties. The Face Clues have also been used in several schools to teach auditory discrimination, pronunciation and phonics in the mother tongue.The Face Clues effectively illustrate the differences between the sounds of the mother tongue and the new/unique sounds found in the second language.
The Translated Echolalia of a Bilingual Child with Autism
Authors: Shaw-Ridley Gill , Jordaan Heila , Jenga Nosisi
Published: April 2023

This study investigated the phenomenon of translated echolalia in a bilingual child with autism, who was between the ages of 7, 11 and 8,2 years at the time of the study. She presented with instances of echolalia that were direct translations from her first language (Sotho) to her second language (English). In order to explore this phenomenon the subject's use of and proficiency in each language is described. The language assessment included an analysis of her receptive language, pragmatic ability, the language of her responses and an analysis of he': echolalic responses (including her translated echolalia). Furthermore, a cognitive processing profile was obtained in order to determine how this related to her first and second language abilities. Moreover, her theory of mind / perspective-taking ability was assessed as her language selection and translated echolalia suggested poor communicative sensitivity. A model is presented to explain the phenomenon of translated echolalia in this child and the extent to which translation involves the conceptual/semantic system is discussed. It is suggested that under certain conditions translation may occur at a lexical rather than a semantic/conceptual level.

Published: April 2023

Background:

Vitamin D deficiency is one of the most common vitamin deficiencies in the world, afflicting over 1-billion children. Currently, there is a shortage of studies evaluating Vitamin D levels in pediatric limb lengthening or deformity correction (LLDC) patients. The purpose of this study is to determine the prevalence of Vitamin D deficiency in pediatric patients undergoing lower extremity osteotomies for LLDC.

Materials and Methods:

We retrospectively analyzed pediatric patients undergoing a lower extremity long bone osteotomy for lengthening/deformity correction at a single center from 2014 to 2018. Of 214 subjects, 80% had perioperative 25-hydroxyvitamin D (25[OH]D) levels available. Variables included age, sex, race, diagnosis, long bone treated, and perioperative 25(OH) D levels. Most patients were female, Caucasian, had a congenital diagnosis, and averaged 12.7 years old.

Results:

A single long bone was treated in 138 subjects (80%), while 19 patients (11%) underwent ipsilateral femur and tibial surgery and 15 patients (9%) underwent a bilateral surgery. The mean 25(OH)D level was 28.7 ng/mL. Deficient levels were found in 32% of subjects, and insufficient levels were found in an additional 41%. All patients healed appropriately.

Conclusions:

LLDC requires optimal bone metabolism for the generation of new bone. This study revealed a high proportion of Vitamin D insufficiency in pediatric limb-lengthening patients. Identifying these patients preoperatively may allow for Vitamin D “prehabilitation” to optimize bone health before limb-lengthening procedures in order to obtain satisfactory outcomes.

Osservazioni sul ritorno al potere dei media.gli effetti alungo termine
Authors: González Gaitano Norberto
Published: April 2023

La teoría de la agenda-setting y la de la espiral del silencio, que han subrayado los efectos cognitivos de los medios de comunicación social, han impulsado simultáneamente de nuevo la exploración de otros efectos a largo plazo, poniendo de moda otra vez el paradigma del "powerful media". La manualística académica pasó por alto las advertencias críticas de los investigadores que acuñaron la teoría de los efectos limitados sobre el alcance limitado de su investigación, y se ha descuidado la investigación acerca de los efectos sociales duraderos de los medios. En este artículo se exploran provisionalmente dos de esos efectos posibles a largo plazo: la pérdida de la experiencia de la realidad y el consiguiente desorientación en el ámbito valorativo, y la desinformación por "sobredosis" de información. A la vez se subrayan las limitaciones históricas y naturales de la investigación sobre los efectos sociales de los medios, mostrando así el largo camino que queda por recorrer en un campo de la "mass communication research" que es, paradójicamente, el de mayor tradición y, sin duda, uno de los que mayor literatura académica ha generado.

The clinical features and outcomes of tuberculosis (TB) and COVID-19 coinfection are not well established. This short report describes 11 people with TB/COVID-19 coinfection in Uganda. The mean age was 46.9 ± 14.5 years; eight (72.7%) were male and two (18.2%) were coinfected with HIV. All patients presented with cough whose median duration was 71.1 (interquartile range, 33.1, 109) days. Eight (72.7%) had mild COVID-19 whereas two (18.2%) died, including one with advanced HIV disease. All patients were treated with first-line anti-TB drugs and adjunct therapy for COVID-19 using national treatment guidelines. This report presents the possibility of the coexistence of the two diseases and calls for more vigilance, screening, and collective prevention measures for both COVID-19 and TB.

JEZIK, KNJIŽEVNOST, MOĆ/LANGUAGE, LITERATURE, POWER
Authors: Autora Grupa
Published: April 2023

Tematski zbornik radova koji je pred vama, Jezik, književnost, moć, obeležava jubilej koji u životu jedne naučne konferencije i nije tako mali: petnaest godina održavanja multidisciplinarnog skupa sa međunarodnim učešćem na Filozofskom fakultetu Univerziteta u Nišu. Svake godine u približno isto vreme okupljali smo se na fakultetu u prostorijama Departmana za anglistiku ili zaposedali čitav sprat, zavisno od broja učesnika, i razgovarali o temama koje su nam se činile važnim za dati trenutak, a sve u kontekstu jezika i književnosti. Započeli smo 2007. godine sa temom politika, 2008. je to bila globalizacija, 2009. identitet, 2010. promene, 2011. komunikacija, 2012. vrednosti, 2013. marginalizacija, 2014. diskurs, 2015. značenje, 2016. vreme, 2017. prostor, 2018. teorija, 2019. kontekst, 2021. alterantive, a 2022. moć. Poslednja dva skupa su, u uslovima pandemije, održana u onlajn formatu. Iza ovih petnaest skupova ostaju 24 publikacije, jer su zbornici radova ponekad objavljivani u dva odvojena toma, jezička i književna istraživanja. Cilj nam je od samog početka bio, pre svega, da oživimo naučnu delatnost među mlađim i nadarenim istraživačima i univerzitetskim nastavnicima, što je jedan od ciljeva Strategije za naučni i tehnološki razvoj, uvodeći ih u akademski diskurs i izdavačku delatnost. Takođe, želeli smo da okupimo kolege sa što više različitih departmana iz što šireg okruženja i omogućimo interdisciplinarnost, kao i da podupremo razvoj naučnoistraživačkog kadra i ojačamo ljudske resurse uspostavljanjem trajne i plodne međuuniverzitetske saradnje. Praksa pokazuje da se naši ciljevi veoma uspešno realizuju, što nam daje volju da nastavimo, podmlađeni i ojačani kolegama nove generacije.
ХУМОР КАО НАЧИН ИСКАЗИВАЊА НАДМОЋИ ВОДИТЕЉА У КВИЗУ „НАЈСЛАБИЈА КАРИКА“
Authors: Тодоровић Милан , Спасић Наташа
Published: April 2023

In this paper we study the different ways in which humor is utilized in the TV quiz show “The Weakest Link” (the version broadcast in the USA during 2020). The aim of examining humor in this context was to show the way the host uses humor to exercise her position of power over the contestants. We used the theoretical frameworks of Dynel, Culpeper and Haugh to explain the different forms of humor, adding other authors where additional explanations were needed. We can observe the following schemas of humor that the show host uses: (1) the host uses wordplay to (subtly) mock the intelligence and knowledge of the contestants; (2) the host uses the contestants’ vocations and hobbies as a basis for her ironic and sarcastic comments; (3) the host, via metalanguage, jests about the quiz format, the television setting or pop culture in general; (4) the host comments on the interaction between the contestants in a humoristic way.
TITLES ASSOCIATED WITH POWER IN A CORPUS OF FICTIONAL PROSE IN ITALIAN (XIX-XXI CENTURY)
Authors: Carlotta Sciumbata Floriana
Published: April 2023

This study investigates whether and how titles related to military ranks, religious roles, and nobiliary titles, representing power and privileges, have changed and distributed throughout the last two centuries in literary works in Italian. Furthermore, the study focusses on possible differences between prose originally written in Italian and translations. The initial hypotheses are that, with social changes, the idea of power evolved as well, thus ‘traditional’ power titles diminished over time, and that historical events caused differences in the representation of power in Italian and foreign literature. The study is based on a corpus of fictional prose written by Italian authors and translated into Italian from other languages between 1800 and 2005 (~8,000,000 words). The extraction is conducted using automatic methods: a list of words related to figures of power is created using WikiData, then items are found and counted in the corpus using ad hoc scripts. Although limits imposed by genres and topics in such a specific lexical extraction, which makes data too scarce to be statistically significant, observing trends partially confirms the initial hypotheses, as a generally descending tendency and small differences between the two sections of the corpus can be detected.
