Probabilistic models for live loads in buildings: critical review, comparison to Brazilian design standards and calibration of partial safety factors
Authors: Costa Luis Gustavo Lopes , Santiago Wagner Carvalho , Beck André Teófilo
Published: September 2022

abstract: Nowadays, structural “limit state” design is made using characteristic or nominal values of actions, partial safety factors and load combination factors. The actual loading that a structure will be subjected to throughout its life is not known at the design phase. Yet, probabilistic models of such loadings are useful for the rational determination of partial safety factors and load combination factors. The probabilistic model leading to nominal live loads of NBR 6120:2019 (Design Loads for Structures) has never been openly discussed. Herein a simple probabilistic model describing spatial and temporal variabilities of live loads in buildings is presented and discussed. The model is built as a sum of two stochastic processes representing the sustained and intermittent parts of the live load. Model parameters are the ones recommended by the Joint Committee on Structural Safety (JCSS), based on extensive surveys done in several countries. By way of Monte Carlo simulations, sample values of live load actions are obtained for buildings of different occupancy types. These values are compared with those recommended by international standards, and those recommended in NBR 6120:2019 and NBR 8681:2003 (Actions and Safety of Structures). The corresponding statistics for the fifty-year extreme and arbitrary point-in-time distributions of live loads are presented; these statistics are very relevant for reliability analyses and for reliability-based code calibration. The stochastic live load model is also employed in a reliability-based calibration to obtain partial safety factors and load combination factors to be used in Brazilian design codes, for ultimate and serviceability limit state verifications.

Authors: Ribeiro Igor José Santos , Pessoa José Renato de Castro , Bittencourt Túlio Nogueira
Published: September 2022

abstract: The study of shear failure in concrete beams is one of the subjects growing in importance due to both the recent reformulations, and increasingly higher cross-section depths used. For instance, the recent updates in the ACI 318 (2019) shows the need to incorporate the size effect in the design of reinforced concrete elements. In this study, the same database adopted by the ACI-ASCE Committee DAfStb 445-D has been used to calculate shear strength, with and without the consideration of size effect, i.e., the design prescribed by ACI 318 (2014), ACI 318 (2019), Frosch et al. (2017), and the ABNT NBR 6118 (2014). Later these predictions are compared with test results. A dispersion analysis has outlined the trends regarding compressive strength, span to depth ratio, longitudinal reinforcement ratio and beam depth. Every variable was discussed per interval, delineating the causes related to the observable trends. Regarding the most prominent influences (effective depth and longitudinal reinforcement ratio), the approaches considering them directly through factors had provided results with no appreciable trends, with lower coefficients of variation (COV) and substantially more conservative for higher cross-section depths. As the Brazilian code does not consider both, a correction factors, determined by a two-step regression analysis on these parameters to adjust this design, are briefly introduced.
Seismic analysis of a concrete gravity dam considering dam–water–sediment–foundation interaction
Authors: Srivastava Ranjit Kumar , Sahoo Dipti Ranjan
Published: September 2022

The dynamic behaviour of a concrete gravity dam–reservoir water–sediment–foundation system is very complex under seismic loading conditions. This study focuses on the investigation of the effects of variations in the material properties of a dam monolith and foundation bed, the consideration of with- and without-slip conditions at the dam–foundation interface and the variation in slope of settled bed-load sediment on the seismic behaviour of a concrete gravity dam. A finite-element model of the Koyna dam in India has been developed in the Abaqus software program to investigate the behaviour of the dam–reservoir–sediment–foundation interaction. The Koyna earthquake excitations in both horizontal and vertical directions of the dam have been used as the input data for the dynamic analysis. The main parameters investigated are contact pressure, friction shear stress at dam heel, heel stresses, crest displacement and accelerations, and tension damage. The findings of this numerical study are also compared with the results predicted from the analytical models proposed by Westergaard and Darbre using the added-mass concept for the reservoir effect.

Published: September 2022

The mass production of antibiotics in the 1940s enabled their travel beyond Europe and America, but to date the significance of the ways in which these medicines co-constituted colonial regimes at the time has not been systematically described. Through a case study of yaws and syphilis, this research article traces arrivals of antibiotics in three countries of Eastern Africa—Malawi, Zimbabwe, and Uganda. We draw attention to the emergent roles of antibiotics at the intersection of colonial governance and humanitarianism in these different settings. Through this analysis of archival and ethnographic materials, we explore how antibiotics became ‘infrastructural’ in material, affective, and political ways. Achieving a better understanding of the entanglement of antibiotics with human systems and lives is crucial to address the pressing issue of antimicrobial resistance (AMR). With this article we join in the global multidisciplinary efforts to tackle AMR, pointing out the often-overlooked role of colonial history in the circulation of antibiotic drugs, and opening a line of research that will provide valuable insights for the development of effective measures to prevent and reduce the spread of antibiotic resistance.
Reconsidering the Declaration of ‘Crisis’ While Living through One
Authors: Trnka Susanna
Published: September 2022

What counts as a ‘crisis’? How do we determine an ‘emergency’? Who gets to do so, and what exactly is at stake? Scholarly examinations of ‘crises’, including, most notably, seminal work by Janet Roitman (2013), frequently underscores how the ‘crisis imaginary’ is employed to rapidly and unjustifiably expand State power. Certainly, State responses to the COVID-19 pandemic have amply demonstrated this critique, as was noted early on by both Agamben (2020) and Chomsky (2020). Nonetheless, regardless of its political manipulations, crisis can also be understood as a phenomenological state, as there exist moments during which we collectively experience being plunged into a radically different time-space that is perhaps best conceptualised as a ‘collective critical event’. Such ‘extraordinary’ times have been denoted as events beyond the scope of narration (Briggs 2003); ‘failure[s] of the grammar of the ordinary’ (Das 2007); or moments of incredulity that surpass our capacities of narration. By focusing on the languaging of the COVID-19 pandemic in Aotearoa/New Zealand, this Position Piece grapples with how to reconcile the insights offered by critiques of the political deployment of claims of ‘crises’ with anthropological and other phenomenological accounts of experiences of moments of profound upheaval.

Published: September 2022

The study purpose was to investigate the correlation between the objective results of measurements of somatometric and physiometric indicators of physical development and the subjective indicators of its self-description for students of 5th and 9th grades.
Materials and methods. The study was conducted in Lutsk secondary school 17 involving 120 secondary school students (aged 10 and 15) as participants. Research methods: analysis of data of scientific and methodical literature, normative-legal documents, programs on physical culture, pedagogical testing of physical fitness, methods of mathematical statistics, E.V. Bochenkova test-questionnaire “Self-description of physical development”.
Results. The correlation analysis between the results in mobility tests for strength, endurance, coordination and flexibility and self-assessment of these indicators by students of 5th and 9th grades shows that they differ. The 9th graders evaluate their physical abilities more objectively. This is due to gaining practical experience in physical education classes. The inadequacy of self-assessment of physical abilities shows that insufficient attention is paid to substantiating the importance of pedagogical control of physical fitness of students during the physical education classes.
Conclusions. The study demonstrates the inadequacy of self-assessment of physical fitness by students, which indicates the importance of theoretical presentation and practical implementation in physical education classes of pedagogical control and self-control of physical fitness, which should be an incentive for boys and girls’ self-improvement in physical education.

Authors: Salafi Muhammad Irvan Eva , Suherman Wawan Sundawan , Suhartini Bernadeta , Antoni Muhammad Sigit , Pratama Kukuh Wahyudin
Published: September 2022

Study purpose. Agility plays an essential role in basketball so increased agility needs to be a concern in the physical conditioning exercises of basketball players. To achieve the best results possible with an exercise, the type and manner of the exercise must be considered. The more varied is the training model offered to athletes, the more will it further encourage athletes not to feel exhausted while training. However, the training model used is still limited to hard textured courts. Though the use of textured fields such as water and sand has an impact other than power load, it lowers the rate of injury.

Materials and methods. The method used in this study was a 2 x 2 factorial design experiment. This study involved 36 men's basketball athletes ages 16–18. The leg power instrument used a vertical jump, agility assessment used an agility test, and analysis of this study data used the ANOVA test.

Results. (1) the sand exercise method shows higher results than the water exercise method; (2) athletes who have high limb power are better in agility testing than athletes who have low limb power; and (3) there is an interaction of water exercise and sand exercise methods and power of the limbs against agility.

Conclusions. The results of this study could prove that sand exercise methods are more effectively used in increasing agility to be an alternative for coaches.

Authors: Yunak Iryna , Ivashchenko Olha , Nosko Mykola , Nosko Yulia
Published: September 2022

The purpose of the study was to determine the age-specific features of fundamental movement skills formation in elementary school students.

Materials and methods. The study participants were boys aged 7 to 10 (24 boys aged 7; 28 boys aged 8; 35 boys aged 9; 36 boys aged 10). The children and their parents or legal guardians were fully informed about all the special aspects of the study and all the parents or legal guardians gave their consent thereto. The study protocol was approved by the Ethics Committee of the University. 

The features of teaching 7–10-year-old boys to throw a ball at a vertical target were investigated. The proficiency level in throwing exercises in class was assessed using an alternative method (“performed”, “failed”), the probability of the exercise performance was calculated (p = n/m, where n is the number of successful attempts, m is the total number of attempts). A method of algorithmic instructions was used in teaching boys aged 7 to 10. The study materials were processed by IBM SPSS 20 statistical analysis software. A discriminant analysis was conducted. 

Results. It was established that the first canonical function explains 64.5% of the variation in results, while the second one does 34.4%, which indicates their high informativity (r1 = 0.762; r2 = 0.652). The materials of the canonical function analysis show the statistical significance of the first and second canonical functions (λ1 = 0.236; р1 = 0.001; λ2 = 0.5633; р2 = 0.001). The first and second functions have a high discriminative ability and value in interpretation with respect to the general population. 

Conclusions. The discriminant analysis made it possible to determine the age-specific features of throwing skills formation in boys aged 7 to 10; answer the questions to which extent the differences in the effectiveness of skills formation in boys aged 7 to 10 are significant; which motor tasks are the most specific to boys aged 7, 8, 9, 10; which class an object belongs to based on the values of discriminant variables. 

It was established that the level of proficiency in exercise 4 “Throwing a ball forward-upward standing with the left side to the throwing direction” has the greatest effect on the process of throwing movement skills formation in boys aged 7 to 10. For boys aged 8 to 10, such an exercise is “Throwing a ball forward-upward standing feet apart”, and for boys aged 9 to 10, such an exercise is “Throwing a ball at a target 3 m away”.

Published: September 2022

Air pollution is a significant health risk factor. Long-term exposure to ambient air pollution has a significant impact on chronic respiratory illnesses and diseases related to health problems. The aim of this study was to investigate the association between air pollution, respiratory diseases and diseases related to health in Northern Thailand. The daily mean concentrations of PM10 and PM2.5, including meteorological condition data from 2015 to 2020, were measured and recorded by Pollution Control Department (PCD), Ministry of Natural Resources and Environment, Thailand. The daily cumulative number of respiratory diseases and related health problems data from 2015 to 2020 was measured and recorded by Information and Communication Technology Centre, Ministry of Public Health, Thailand. The daily mean concentrations of PM10 and PM2.5 were positively associated with CO, NO2, SO2, O3, circulatory system (I00-I99), respiratory system (J00-J99.8), eye (H10-H19.8), rash and other nonspecific skin eruption (R21), and neoplasms (C00-D48). After adjusting for confounding factors, the multiple linear regression analysis revealed that the escalating daily mean PM10 concentrations were connected to the increasing daily mean PM2.5 concentrations. This indicates that providing health education programmes and pollution protection, as well as policymakers and legislation, is required for better health.
Performance of a Novel Hybrid Model Through Simulation and Historical Financial Data
Authors: Hossain Md. Jamal , Ismail Mohd Tahir
Published: September 2022

It is thoroughly acknowledged that the historical financial time series is not linear, exhibits structural changes, and is volatile. It has been noticed in the current literature that because of the existence of structural breaks in the historical time series, the GARCH family models provide misleading results and poor forecasts. Thus, it is unavoidable to incorporate models with nonlinearity in the conditional mean and conditional variance to capture volatility dynamics more precisely than the existing models. Therefore, inspiring in this matter, this study proposes a novel hybrid model of exponential autoregressive (ExpAR) with a Markov-switching GARCH (MSGARCH) model. This study also examines volatility dynamics and performances through simulation and real-world financial data. Moreover, this study investigates downside risk management performances using 5% VaR (Value-at-Risk) back-testing. The empirical findings showed that the proposed model outperforms the benchmark model for both simulation and real-world time series data. The VaR results also showed that the proposed model captures downside risk more meticulously than the benchmark model.

Resultados: gestantes negras apresentaram taxa média de prevalência de 65,18% das internações e 70,85% dos óbitos por COVID-19 no ano de 2020. Por outro lado, a taxa média de prevalência de internações e óbitos entre gestantes brancas foi de 32,32% e 27,23%, respectivamente. Conclusão: A maior dificuldade no acesso ao pré-natal, a alta taxa de prevalência de comorbidades, as precárias condições de trabalho e dificuldade de afastamento durante a pandemia, o racismo institucional e a necropolítica adotada pelo Estado Brasileiro são possíveis explicações para essa expressiva situação de vulnerabilidade.
Legal Foundation of Contractual Relations Regulation in Cross-Border Supply Chains
Authors: Fonotova O. V.
Published: September 2022

Global value chains (supply chains) have attracted close attention of representatives of the scientific, business and political circles. Foreign scholars and researchers have convincingly proved that the global value chain is an independent object for study in international commercial law.In recent years, the leading European legal systems have strengthened the protection of the most vulnerable participants in cross-border relations: workers, other individuals affected by the negative impact of global supply flows. In France, the UK, the Netherlands, Germany, Switzerland, as well as at the supranational level in the EU, legislation regulating supply chains is developing. By assigning responsibility to large corporations for cross border violations committed in chains coordinated by them, foreign law is focused on solving socially significant tasks.From a legal point of view, the supply chain is a complex, multi-level system of contracts subordinated to a uniform economic goal. The dominant legal regulation of private relations within supply chains has a non-state origin and is formed by private entities, mainly large multinational corporations. To explain the legal effect of such global regulatory systems, the paper introduces the concept of a «transnational legal order» based on the mechanisms of private law. The transnational legal order, along with the formation of binding (contractual) ties between entities, plays a unifying — organizing and coordinating — role in supply chains. In addition, it creates a platform for the international dissemination of national norms of law, as well as «voluntary» standards and rules formulated in private, social and ethical practices that are not initially endowed with legal force. The contractual form of consolidation contributes to their legitimization. The paper justifies the emergence of a new direction of research in the framework of international commercial law — transnational supply chain law.The trends in the development of international commercial law include digitalization, environmentalization, socialization, industry fragmentation and extraterritoriality of regulation.
Goals Manipulation Technologies in Legal Regulation: Topical Issues of Theory and Practice
Authors: Kulikov M. A.
Published: September 2022

Manipulative technologies have become widespread in various fields and are used in the process of legal regulation of public relations. The fact that representatives the theory of law and branch legal sciences ignore this form of legal influence on social processes can lead not only to a biased understanding of certain stages of the mechanism of legal regulation, but also to an obvious leveling of the social conditionality of the legal technique used in law-making, law-realization and law interpretation processes. The paper gives the main focus to the concept and signs of manipulation as a generic concept that manifests itself in a specific way in the process of legal influence on public relations. The author proposes his definition of manipulation and technologies of manipulation of legal goals in legal regulation. The concept of technologies for manipulating legal goals is being formed. It includes six groups of key techniques and methods by which the subject of manipulative influence: a) formulates and objectifies legal goals; b) uses already existing legal goals, coordinating the behavior of participants in legal relations in their own interests; c) stimulates the management object to achieve the set goal through the use of appropriate legal means; d) restricts the activity of the management object that runs counter to the plans of the subject of manipulation. The paper argues the according to which manipulation of legal goals is legitimate behavior, a common way of exercising public power, socially conditioned practice of legal regulation and the legal reality, which is a natural stage in the development of public relations. It is proved that all technologies of manipulation of legal goals are based on legitimate aspirations of participants in legal relations, nevertheless leading to the realization of the interests of the subject of manipulative influence at the expense and to the detriment of the interests of the object of manipulation. Despite the legality of technologies for manipulating legal goals, they can significantly reduce the effectiveness of the mechanism of legal regulation by creating an imbalance in the coexistence of the interests of the individual, society and the state.

Published: September 2022

Based on the analysis of materials of law enforcement practice on the issue of imposing additional insurance services on the borrower at the conclusion of a loan agreement, the most typical cases of violation of the borrower’s rights regarding compliance with their right to refuse additional insurance services, including life and/or health insurance of the borrower, have been identified; providing the borrower with a consumer loan on the same terms if the borrower has independently insured his life, health/ other insurance interest in favor of the lender from the insurer that meets the criteria established by the lender in accordance with the requirements of the legislation; refund to the policyholder of the insurance premium paid in case of refusal of the policyholder from the voluntary insurance contract, etc.

The article proposes at the legislative level to fix the bank’s obligation to reflect in lending documents information about the full cost of the loan with the presence of risk insurance, as well as information about the full cost of the loan without the purchase of insurance services, and, accordingly, the consolidation of this right in the insurance policy, which will give the relationship between the bank and the borrower more transparency.

Background. Surgical treatment of malleoli injuries is performed according to the principles of articular fractures management. It is particularly true for ankle injuries involving fractures of posterior edge of the tibia. The posteromedial approach enables to improve the results of surgical treatment of patients due to the direct reduction of tibia fragments.
Aim of the study to evaluate the efficacy and advisability of the modified posteromedial approach in patients with unstable fractures of malleoli and posterior edge of the tibia.
Methods. Twenty two patients with unstable fractures of malleoli and posterior edge of the tibia underwent surgical treatment via the posteromedial approach. The X-ray control was performed the next day after the surgery as well as 6, 12, 24 and 48 weeks from the osteosynthesis. The functional results were evaluated in 12, 24 and 48 weeks after the surgery with the use of AOFAS and Neer scales.
Results. The average duration of postoperative period (9.33.8 days) was mainly determined by the state of the soft tissues. 91% of patients had anatomical reduction of posterior edge fragment of the tibia, 17 (77%) from 22 patients demonstrated fracture consolidation in X-rays 12 weeks after the surgery and all 22 patients (100%) 24 weeks after surgery. There were no cases of postoperative complications in patients 24 weeks after the surgery. While managing patients the range of motion in the ankle joint increased from 41.16.9 12 weeks after the surgery to 57.34.6 48 weeks after the surgery, that was statistically significant (p0.01). The functional results improved as well according to both AOFAS and Neer scales and this improvement was also statistically significant (p0.01).
Conclusion. The is rather effective in Patients with unstable fractures of malleoli and posterior edge of the tibia had a statistically significant improvement in function after posteromedial approach.

AIM: We endeavored to evaluate the efficacy of Lurasidone at doses of 40160 mg per day on symptoms of schizophrenia associated with symptoms of depression in real clinical practice in a Russian patient population.
METHODS: One hundred sixty eight patients aged 1865 years old, who at the time of the start of the observation were being treated in a hospital or day hospital due to an exacerbation of paranoid schizophrenia accompanied by symptoms of depression, were prescribed lurasidone. Treatment with lurasidone and other concomitant drugs, their prescription, withdrawal, selection, and dose modifications were determined based on the indications for the use of those drugs and the recommended doses in the instructions, clinical need, and patient interests, rather than by the goals of the study. During the observation period, the severity of depressive symptoms according to the Calgary Depression Scale (CDSS) and that of psychotic symptoms according to the Positive and Negative Syndrome Scale (PANSS) were assessed six times (before the start of treatment and then on the 4th, 7th, 14th, 28th, and 42nd days).
RESULTS: A statistically significant reduction in the severity of the symptoms was observed with the use of lurasidone in doses ranging from 40 mg to 160 mg per day. The fastest and most significant (p 0.001) reductions in the total PANSS and CDSS scores were observed with lurasidone 120 mg. A somewhat lower efficacy of lurasidone was observed at a dose of 160 mg. The largest reductions in the total PANSS and CDSS scores with lurasidone 120 mg were associated with the highest survival rate and the longest median time from treatment initiation to discontinuation or follow-up. The most commonly reported side effects with lurasidone in this study (nausea, akathisia, tremor and drowsiness) were consistent with the known safety profile of the drug. Adverse events in most cases were assessed as mild, or occasionally moderate.
CONCLUSION: A six-week prospective observational study of the real-world clinical effectiveness of lurasidone in doses ranging from 40 mg to 160 mg per day established statistically and clinically significant improvements in both psychotic and depressive symptoms in patients with acute exacerbation of schizophrenia and associated symptoms of depression.
The effect of content retelling on incidental vocabulary acquisition for Chinese EFL learners
Authors: Jin Jingyi , Li Shuguang
Published: September 2022

As the foundation of English learning, the acquisition of vocabulary has always been a hot topic in the fields of second language acquisition and foreign language teaching. Contrasted with intentional vocabulary acquisition, incidental vocabulary acquisition (IVA) relates to lexical gains as a by-product of main cognitive activities. In the field of teaching English as a foreign language (TEFL) in Chinese high schools, the incidental acquisition of English vocabulary has increasingly attracted the academic attention in recent years. However, few empirical studies have focused on the incidental acquisition of English vocabulary engendered by doing content retelling tasks. In light of the inadequacy, this study adopted the quality audio-visual material as input and content retelling as output (forming an input-output-input circle), aiming at exploring the effect of retelling on Chinese high school EFL learners’ IVA. Results indicated that learners who retold the content of the audio-visual material between two viewings can pick up more words. In this process, the attempted use of new words in oral reproduction plays a positive role in strengthening the immediate acquisition and long-term retention of the target words.

A young man presented with complaints of right upper quadrant pain for 6 months, past history revealed he is a known case of Haemophilia A, which is a challenge for surgeons and anaesthetist to manage intraoperative and postoperative bleeding, henceforth referred to Haematology, department of pathology. Soon after taking clinical history patient was subjected for haemostatic screening tests such as PT, APTT, mixing studies, inhibitors screening and factor VIII assay revealed patient is a case of several haemophilic with negative for inhibitors and elevated APTT values. Patient is prepared for surgery only after giving Anti haemophilic factor replacement and preoperatively achieving 100% haemostasis by raising Factor VIII assay to 100%. Intra and post operatively patient is constantly monitored for bleeding. Post operatively every 12hrs patient was infused with anti-haemophilic factor variable levels and tapering doses to maintain constant haemostasis as the factor VIII half-life is less than 12 hours. Patient was haemodynamically stable when discharged that is 7 day post-surgery. Thus, we presenting a case how to manage haemophiliacs in a simple way for any kind of surgery with availability of antihemophilic factors and expertise in maintaining the haemostasis as build up confidence among surgeons.

Image-based features of breast cancers have an important role in clinical prognostics, such as grading breast invasive carcinoma (BIC). Magnification is useful for investigating poorly defined abnormal tissue present in mammogram images. But, the disadvantage of viewing at a higher magnification is that less of the slide can be viewed. So, the question raised on which scale of magnification is better for grading BIC. In this study, the four scales of magnification such as 4x, 10x, 20x, and 40x are considered to evaluate their contribution towards BIC grading in deep learning, transfer learning, and the traditional machine learning approach. Here, 13 CNN models are considered for the transfer learning approach. In the deep learning approach, the deep feature of 13 CNN models with three classifiers is considered. Further, the handcrafted feature such as LBP, HOG, and GLCM with three classifiers like SVM, KNN, and Naïve Bayes are evaluated for grading of BIC. Finally, the 40x scale of magnification performed better in all classification models.

Published: September 2022

The Constrained Application Protocol (CoAP) is extensively used in several industrial Internet of Things (IoT) applications. Using heavy-weight algorithms is not feasible in resource-constrained IoT environments, and lightweight solutions are vulnerable to security attacks. The trade-off between computing cost and security strength plays a significant role in deciding the right solution. Therefore, developing a lightweight security mechanism with a higher security level is paramount. Therefore, a lightweight authentication with Two-way Encryption for Secure Transmission in CoAP Protocol (LATEST) was proposed to achieve secure data transfer with a lightweight security mechanism. The proposed LATEST ensures high confidentiality and integrity against modification, impersonation, and replay attacks. Security analysis and validation tests are performed with the help of validation tools to measure the strength of the proposed LATEST mechanism. Testing and validation proved that the performance and security level improved significantly.

Inovação lexical na rede social: as criações neológicas para nomes de festas universitárias no Facebook
Authors: Oliveira Silva Maiune De , Castorino Pauler , Xavier Vanessa Regina Duarte
Published: September 2022

As criações lexicais são recorrentes na língua geral e/ou especializada, porque essas inovações linguísticas, compreendidas como neologismos, denominam a quilo que é tido como novidade na realidade dos sujeitos. Neste viés, acreditamos que, na contemporaneidade, essa renovação lexical é disseminada sobretudo por intermédio das redes sociais (GONÇALVES, 2019). Por esse prisma, nesse estudo temos como objetivo investigar os processos neológicos mais frequentes em nomes de festas universitárias divulgados na rede social Facebook. Para isso, utilizaremos como pressupostos teóricos os estudos de Alves (2007), Correia e Almeida (2012), Guilbert (1975), entre outros que versam sobre a temática que ora abordamos. A metodologia tem cunho quanti-qualitativo, posto que coletamos os neologismos manualmente na rede social supramencionada e realizamos o cotejo deles em dicionários gerais de língua, com vistas a conferir seus status neológicos. Nossos resultados apontam que os neologismos formais, em sua maioria composições sintagmáticas e cruzamentos vocabulares, foram os mais recorrentes.
