Published: August 2023

Abstract. Warm boundary layer clouds in the Eastern North Atlantic region exhibit significant diurnal variations in cloud properties. However, the diurnal cycle of the aerosol indirect effect (AIE) for these clouds remains poorly understood. This study takes advantage of recent advancements in the spatial resolution of geostationary satellites to explore the diurnal cycle of AIE by estimating the cloud susceptibilities to changes in cloud droplet number concentration (Nd). Cloud retrievals for four months of July (2018–2021) from SEVIRI on Meteosat-11 over this region are analyzed. Our results reveal a significant "U-shaped" daytime cycle in susceptibilities of cloud liquid water path (LWP), cloud albedo, and cloud fraction. Clouds are found to be more susceptible to Nd perturbations at noon and less susceptible in the morning and evening. The magnitude and sign of cloud susceptibilities depend heavily on the cloud state defined by cloud LWP and precipitation conditions. Non-precipitating thin clouds account for 44 % of all warm boundary layer clouds in July and they contribute the most to the observed diurnal variation. Non-precipitating thick clouds are the least frequent cloud state (10 %), they exhibit more negative LWP and albedo susceptibilities compared to thin clouds. Precipitating clouds are the dominant cloud state (46 %), but their cloud susceptibilities show minimal variation throughout the day. We find evidence that the diurnal cycle of LWP and albedo susceptibilities for non-precipitating clouds are influenced by a combination of the diurnal transition between non-precipitating thick and thin clouds and the "lagged" cloud responses to Nd perturbations. The diurnal cycle in cloud fraction susceptibility for non-precipitating thick clouds can be attributed to the diurnal variation in cloud morphology (e.g., overcast or broken). The dissipation and development of clouds do not adequately explain the observed variation in cloud susceptibilities. Additionally, diurnal variation of cloud susceptibility is primarily driven by variation in the intensity of cloud response rather than the frequency of occurrence of cloud states. Our results imply that polar-orbiting satellites with overpass time at 13:30 local time underestimate daytime mean value of cloud susceptibility, as they observe susceptibility daily minima in the study region.

Abstract. Arctic warming is causing permafrost thaw and release of organic carbon (OC) to fluvial systems. Permafrost-derived OC can be transported downstream and degraded into greenhouse gases that may enhance climate warming. Susceptibility of OC to decomposition depends largely upon its source and composition which varies throughout the seasonally distinct hydrograph. Most studies to date have focused on larger Arctic rivers, yet little is known about carbon dynamics in lower order rivers/streams. Here, we characterize composition and sources of OC, focusing on less studied particulate OC (POC), in smaller waterways within the Kolyma River watershed. Additionally, we examine how watershed characteristics control carbon concentrations. In lower order systems, we find rapid initiation of primary production in response to warm weather, shown by decreasing δ13C-POC, in contrast to larger rivers. As Arctic warming and hydrologic changes may increase OC transfer from smaller waterways through river networks this may intensify inland water carbon outgassing.

Abstract. Wildfire behaviour depends on complex interactions between fuels,
topography, and weather over a wide range of scales, being important for
fire research and management applications. To allow for significant
progress towards better fire management, the operational and research
communities require detailed open data on observed wildfire behaviour. Here,
we present the Portuguese Large Wildfire Spread database (PT-FireSprd) that
includes the reconstruction of the spread of 80 large wildfires that
occurred in Portugal between 2015 and 2021. It includes a detailed set of
fire behaviour descriptors, such as rate of spread (ROS), fire growth rate
(FGR), and fire radiative energy (FRE). The wildfires were reconstructed by
converging evidence from complementary data sources, such as satellite
imagery and products, airborne and ground data collected by fire personnel, and
official fire data and information in external reports. We then implemented
a digraph-based algorithm to estimate the fire behaviour descriptors and
combined it with the Meteosat Second Generation (MSG) Spinning Enhanced Visible and Infrared Imager (SEVIRI) fire radiative power estimates. A total of 1197
ROS and FGR estimates were calculated along with 609 FRE estimates. The
extreme fires of 2017 were responsible for the maximum observed values of
ROS (8900 m h−1) and FGR (4400 ha h−1). Combining both descriptors, we describe
the fire behaviour distribution using six percentile intervals that can be
easily communicated to both research and management communities. Analysis of
the database showed that burned extent is mostly determined by FGR rather
than by ROS. Finally, we explored a practical example to show how the
PT-FireSprd database can be used to study the dynamics of individual
wildfires and to build robust case studies for training and capacity
building. The PT-FireSprd is the first open-access fire progression and behaviour
database in Mediterranean Europe, dramatically expanding the extant
information. Updating the PT-FireSprd database will require a continuous
joint effort by researchers and fire personnel. PT-FireSprd data are
publicly available through https://doi.org/10.5281/zenodo.7495506 (Benali
et al., 2022) and have large potential to improve current
knowledge on wildfire behaviour and to support better decision making.
Climate model Selection by Independence, Performance, and Spread (ClimSIPS v1.0.1) for regional applications

Published: August 2023

Abstract. As the number of models in Coupled Model Intercomparison Project (CMIP) archives increase from generation to generation, there is a pressing need for guidance on how to interpret and best use the abundance of newly available climate information. Users of the latest CMIP6 seeking to draw conclusions about model agreement must contend with an “ensemble of opportunity” containing similar models that appear under different names. Those who used the previous CMIP5 as a basis for downstream applications must filter through hundreds of new CMIP6 simulations to find several best suited to their region, season, and climate horizon of interest. Here we present methods to address both issues, model dependence and model subselection, to help users previously anchored in CMIP5 to navigate CMIP6 and multi-model ensembles in general. In Part I, we refine a definition of model dependence based on climate output, initially employed in Climate model Weighting by Independence and Performance (ClimWIP), to designate discrete model families within CMIP5 and CMIP6. We show that the increased presence of model families in CMIP6 bolsters the upper mode of the ensemble's bimodal effective equilibrium climate sensitivity (ECS) distribution. Accounting for the mismatch in representation between model families and individual model runs shifts the CMIP6 ECS median and 75th percentile down by 0.43 ∘C, achieving better alignment with CMIP5's ECS distribution. In Part II, we present a new approach to model subselection based on cost function minimization, Climate model Selection by Independence, Performance, and Spread (ClimSIPS). ClimSIPS selects sets of CMIP models based on the relative importance a user ascribes to model independence (as defined in Part I), model performance, and ensemble spread in projected climate outcome. We demonstrate ClimSIPS by selecting sets of three to five models from CMIP6 for European applications, evaluating the performance from the agreement with the observed mean climate and the spread in outcome from the projected mid-century change in surface air temperature and precipitation. To accommodate different use cases, we explore two ways to represent models with multiple members in ClimSIPS, first, by ensemble mean and, second, by an individual ensemble member that maximizes mid-century change diversity within the CMIP overall. Because different combinations of models are selected by the cost function for different balances of independence, performance, and spread priority, we present all selected subsets in ternary contour “subselection triangles” and guide users with recommendations based on further qualitative selection standards. ClimSIPS represents a novel framework to select models in an informed, efficient, and transparent manner and addresses the growing need for guidance and simple tools, so those seeking climate services can navigate the increasingly complex CMIP landscape.
Brief communication: Comparison of in situ ephemeral snow depth measurements over a mixed-use temperate forest landscape

Published: August 2023

Abstract. The accuracy and precision of snow depth measurements
depend on the measuring device and the conditions of the site and snowpack
in which it is being used. This study compares collocated snow depth
measurements from a magnaprobe snow depth probe and a Federal snow tube in
an ephemeral snow environment. We conducted three snow depth sampling
campaigns from December 2020 to February 2021 that included 39 open-field and
coniferous-, mixed-, and deciduous-forest sampling sites in Durham, New
Hampshire, United States. For all sampling campaigns and land cover types,
with a total of 936 paired observations, the magnaprobe snow depth
measurements were consistently deeper than those of the snow tube. There was a 12 %
average difference between the magnaprobe (14.9 cm) and snow tube (13.2 cm)
average snow depths with a greater difference in the forest (1.9 cm) than
the field (1.3 cm). This study suggests that snow depth measurements using a
Federal snow tube can avoid overprobing with an ephemeral snowpack in
forested environments.
Segmented Gurney Flaps for Enhanced Wind Turbine Wake Recovery

Published: August 2023

Abstract. The wind turbine wake is a downstream region of velocity deficit, featuring higher turbulence and a complex helical vortex structure. In low ambient turbulence and low tip speed ratio conditions, the wind turbine wake is extremely stable. The impact of the velocity deficit is a power loss for the downstream wind turbine, which scales with the velocity cube. This study uses field tests and simulations to evaluate segmented Gurney flaps for enhanced wind turbine wake recovery and power output in a wind farm setting; where the power and loads of the retrofitted wind turbine were assessed. Four Gurney flaps were attached to each blade tip of a 3.8 MW research wind turbine. This configuration is hypothesised (in line with an ECN (now TNO Wind Energy) patent) to cause a spatial variation to the stable tip vortex and induce turbulence in the wake for faster wake mixing. Field tests using a scanning LiDAR were conducted to quantify the wind turbine wake recovery between the baseline and the retrofitted configuration in various atmospheric conditions. The results show a consistent increase in wake recovery for the Gurney flap configuration, generally at all downstream distances (span wise averaged deficits reduced by roughly 10 % at hub height, at a downstream distance of 5D), pronounced at low tip speed ratio conditions. Using crude assumptions, this implies a 4 % relative increase in wind farm efficiency for a typical wind farm with outer rows of wind turbines with segmented Gurney flaps. The impact of retrofitting on turbine power and loads remained within the measurement uncertainty band, and this limited effect is confirmed by design load simulations. In this work, a very successful field test campaign was executed which demonstrated the use of segmented Gurney Flaps as a promising add-on to promote enhanced wind turbine wake recovery for improved overall wind farm farm performance.

These poems are trying to tell the life stories of two generations of immigrants. Grand-parents immigrated from Crimea to Ottoman Empire, a superpower at the time, but imploding shortly after to a small modern republic, still in trouble, and the grand-children immigrated to the States, a superpower, and experiencing the fear that she might also become soon a third-world country.I prefer not to explicate my poems, they should speak independently. This time, I felt the urge to tell the background story. Forgive my intrusion.

Kerberoasting: Case Studies of an Attack on a Cryptographic Authentication Technology
Authors:   Bridgewater State University, Demers D ,   Bridgewater State University, Lee Hannarae
Published: August 2023

Kerberoasting, an attack vector aimed at the Kerberos authentication protocol, can be used as part of an adversary’s attack arsenal. Kerberos is a type of network authentication protocol that allows a client and server to conduct a mutual verification before providing the requested resource to the client. A successful Kerberoasting attack allows an adversary to leverage the architectural limitations of Kerberos, providing access to user password hashes that can be subject to offline cracking. A cracked user password could give a bad actor the ability to maintain persistence, move laterally, or escalate privileges in a system. Persistence or movement within a system is indispensable to a bad actor. Adversaries may use Kerberoasting to achieve this persistence or movement as part of a more effective attack. These attacks can include ransomware, stealthy removal of data from a system, or building a back door for future access. It is, therefore, vital to understand how Kerberoasting works to detect attacks and mitigate future attempts. We examine cases in which Kerberoasting has played a role in an attack or was used as a tool in an adversary’s arsenal and review the outcomes. We then discuss known ways to detect and mitigate Kerberoasting attacks and analyze how this information can inform enterprise policy.

This research aims to explore the influence of news media on the fear of cyberterrorism and how cyberterrorism is framed in the media. Using a mixed-method approach as a research strategy, this paper reports on two studies that explore the influence of news reading on the fear of cyberterrorism. The first study analyzed survey responses from 1,190 participants and found that increased exposure to reading news media was associated with increased fear of cyberterrorism. The second study, built on the first, sought to investigate how cyberterrorism is framed and constructed as a threat by the US local and national newspapers. The framing and portrayal of cyberterrorism in US newspapers are discussed.
The Relationship between Parenting Practices and Cyberbullying Perpetration: The Mediating Role of Moral Beliefs
Authors: Choi Jaeyong ,   University of Texas at Arlington, Lee Seungmug (Zech) ,   Angelo State University, Dittmann Layne
Published: August 2023

Criminologists and psychologists have long recognized that parenting practices can affect childhood outcomes and the development of moral beliefs in children. Another body of literature provides evidence that morality is a key cause of antisocial behavior. Yet, a noticeable gap in this line of work has been testing the mediation effects of parenting practices on cyberbullying via moral beliefs. Using a sample of South Korean adolescents, we tested whether moral beliefs mediate the relationships between parenting practices and cyberbullying perpetration. Results show that parental supervision and excessive parenting can influence cyberbullying perpetration and that the impact of parenting practices is partially indirect through moral beliefs.

The difference in depression between non-cyberbullied and cyberbullied youth is not well understood. To describe the prevalence and trends in depression among cyberbullied adolescents. Using cross-sectional, nationally-representative data from the YRBS 2011 - 2019, we estimated the prevalence and trends of depression across the total years and within cyberbullied groups that include biological sex and race and ethnicity among adolescents. The results indicated the prevalence of depression was higher among those that were cyberbullied. Within the cyberbullied groups the total trend was higher than the non-cyberbullied, females had a higher prevalence of depression than males, and Hispanics had a higher prevalence of depression than blacks. Further, the results showed the trends for cyberbullied, males, females, whites, and blacks had significant linear increases, but Hispanics remained stable. Further, the non-cyberbullied trend was quadratic where there was no change from 2011-2015, but an increase occurred between 2015-2019. Depression is high among adolescents. It appears to be increasing among individuals that are cyberbullied, with the exception of Hispanics. These results are discussed with programming recommendations.

Media religiosity as a strategy for resilience and overcoming crisis
Authors: Kostruba Natalia
Published: August 2023

The modern world is rapidly changing due to digitalisation and informatisation. Such transformations were forced through the COVID-19 pandemic and affected all spheres of life, including religion. Religion has increased its online presence, and the phenomenon of media religiosity has spread, which determines the relevance of this study. Considering the originality of the concept, the purpose of the study is to provide an empirical analysis of the relationship between media religiosity and personal coping strategies in the context of a crisis associated with pandemic restrictions. To achieve this purpose, the BASIC Ph psychological flexibility test and the questionnaire by N.S. Kostruba on the media religiosity of the individual were used. A theoretical overview and empirical study (online survey) of the possibilities of using media religiosity as a coping strategy for overcoming crisis states in personality are conducted. Empirical evidence revealed that media religious activity is associated with the psychological overcoming of difficult life circumstances and consists in relying on faith and values. The behaviour of people prone to media religiosity in stressful situations is determined by the ability to believe (in oneself, in their own strength, in God, in higher forces, in other people, etc.), to be guided by social support (or appeals for support to the family, relatives, professional circle, or providing assistance to others). It is proved that media religiosity retains a positive psychotherapeutic effect on the life of the individual in conditions of uncertainty and stress. It is also confirmed that even with the mediation of media technologies, religious practices perform the functions of social and emotional support, and provide psychological stability through the search for new meanings in events. The results obtained can become the basis for developing a model of psychological support for the population based on media religious practices and in psychotherapy (as homework or in online counselling).
Paranoid personality type: Relationships with the surroundings
Authors: Spytska Liana
Published: August 2023

The relevance of the study lies in the fact that the transience of changes in the social surrounding requires dynamism and competitiveness from a person, which forces the individual to actively transform the emotional regulation of behaviour, in particular in communication and relationships. However, the adaptive capabilities of a person who is characterised by increased sensitivity to frustration and persistent distrust of others can be considerably limited, and therefore maintaining the mental health of people at risk has become an urgent issue. The purpose of the study is to determine the basis on which character anomalies are formed, to uncover the cause-and-effect relationships in the issue of the development of mental disorders, and to identify possible ways to overcome complications in relationships with the surroundings caused by disturbances in mental activity. At the core of the theoretical and methodological approach lies the combination of methods involving structural-functional analysis of the issue of forming a paranoid personality type and an analytical investigation of the psychological support methods for neuro-mental disorders that affect individual behavioural self-regulation. The empirical basis of the study is questionnaires and diagnostics of the mental states of people prone to personality disorders. The paper clarifies the causes and features of the development of paranoid mental anomalies and the possibilities of prevention and correction of such mental disorders. The presented results reflect the problem of the adaptive capabilities of people with congenital or acquired pathological conditions of the psyche. The paper covers the issues of interaction with the paranoid personality type socially. The most popular concepts of providing psychological assistance are considered. The correctness of the assumption that it is much more difficult for people with a paranoid personality type to cope with frustration and adapt to society is analysed. The results obtained are of practical value for social workers who are engaged in identifying mental health disorders of people at risk and predicting deviant behavioural responses, for practical psychologists who support people with a paranoid personality type, in particular through psychotherapy.

The global population in developed countries is increasing, especially in the age group of 80 years or older, leading to an increase in demand for health services. With aging, there is a decrease in brain activity, which can lead to a reduction in reflexes and sensitivity, changes in attention, and the development of Mild Cognitive Impairment (MCI). Physiotherapy plays a crucial role in maintaining and recovering a healthy and active lifestyle, seeking aging with greater functional independence, and delaying the progression of cognitive decline. Therefore, the present study aimed to develop a physiotherapy protocol for cognitive rehabilitation in the elderly based on a literature review. The protocol can optimize occupational performance and delay the conversion of dementia in elderly people with MCI. In the multidisciplinary team, the physiotherapist can conduct individual or group strategies and interventions with elderly individuals with normal cognitive function, aiming to improve performance in mnemonic tasks and daily activities that require greater cognitive attention. Protocols serve as guides for professionals, leading them to the desired path, and focus on observation and evaluation, aiming at significant contributions to institutions, elderly people, and their families.

The pandemic has highlighted that humanization and care must be inseparable. The abrupt change in the global health landscape underscored the fundamental importance of empathetic human action, extending beyond healthcare equipment. Machines cannot replace the nurse-patient relationship in the pandemic context; thus, the theme of humanization in healthcare becomes crucial for care practices. From this perspective, the aim was to emphasize the importance of nursing care in providing humanized support to patients and their families in the face of COVID-19. This research is of a bibliographic nature. Cross-references were made using the following keywords: "Humanization of Care"; "Nursing"; "Communication"; "Pandemic"; "Covid-19"; and "Patients," in the LILACS, BVS, SciELO, and SANARE databases. Six articles were selected. The results revealed that the humanization of care was essential for establishing a bond of trust and empathy between the healthcare professional and the patient, making the care effective and transcending beyond the biological dimension. It addressed the patient's physical, mental, and emotional needs.

Çevresel konularda yaşanan son dönemdeki gelişmeler devletlerin dikkatinin çevresel problemlere ve çeşitli çözümlere yönelmesine neden olmuştur. Bunun sonucunda birçok devlet ve uluslararası kuruluş çevresel sorunların yol açtığı olumsuzluklar karşısında çeşitli önlemler almıştır. Çevresel koruma önlemleri konusunda giderek artan ihtiyaç, daha fazla finansman kaynağını gerektirmiştir. Bu durumun sonucunda yenilikçi çözümler ortaya atılmaya başlanmış ve bu yenilikçi çözümlerden biri olan çevresel etkili tahvil ile özel yatırımcıların çevresel konuların çözümüne yönelik yatırım yapması sağlanmıştır. Çevresel etkili tahvil, “performansa dayalı ödeme” yapısı ve tüm taraflarına sağladığı faydalar ile öne çıkmasına karşın henüz sadece ABD’de uygulanmıştır. Yarattığı birçok avantaj yanında birtakım dezavantajlara sahip olan çevresel etkili tahviller hala dar bir uygulama alanına sahip olup atık su ve kanalizasyon problemlerinin aşılması ve ormanların dayanıklılığının arttırılması amacıyla uygulanmıştır. Bu çalışmada çevresel etkili tahviller hakkında bilgi verilmiş, özellikleri ve ihraç süreci açıklanmış, tahvilin bileşenleri, örnekleri ve avantajları konuları incelenmiş ve potansiyeline ulaşmasının önündeki engeller belirlenmiştir. Son olarak çevresel etkili tahvilin Türkiye için uygulanabilirliğine değinilmiş ve dünyada uygulanma potansiyeline ulaşması yönünde çeşitli çözüm önerileri sunulmuştur.

Kadınlar kariyer gelişimleri bakımından genel olarak iş yaşamında erkeklere göre daha geri planda kalmaktadırlar. Bazı meslek alanları dışında kadınların iş yaşamında yeterli düzeyde temsil edilmediği söylenebilir. Bunun bir sonucu olarak yöneticilik pozisyonları kadınlar açısından ulaşılması daha zor kariyer basamaklarıdır. Kadınlara fizyolojik özellikleri nedeniyle yüklenen sorumluluklar ya da sosyal olarak belirlenen toplumsal roller onların kariyer ilerleme sürecinde karşılaştığı en önemli zorluklar arasındadır. Dolayısıyla fizyolojik ya da sosyal olarak belirlenmiş olan roller kadın yöneticilere yönelik algıyı etkilemektedir. Bu algı kadın yöneticilerin yarattığı iş atmosferi ve yöneticilik başarısı açısından önemli bir faktördür.

Bu çalışma kadın yönetici özelliklerinin iş atmosferi üzerindeki etkisini ele almaktadır. Nicel bir yöntemle gerçekleştirilen araştırmaya çalışan kadınlar katılmıştır. Araştırmaya Antalya’da kamu ve özel sektörde çalışan 221 kadın katılmıştır. Araştırmanın katılımcıları kolayda örneklem yöntemiyle belirlenmiştir. Araştırma verileri ise anket tekniği ile toplanmıştır. Araştırmada kadın yöneticilerin “ilişki yönetme davranışları” ve “iş etiği” özelliklerinin olumlu iş atmosferi üzerinde anlamlı ve pozitif bir etkiye sahip olduğu; “görev yürütme davranışlarının” ise olumsuz iş atmosferi üzerinde anlamlı ve pozitif bir etkiye sahip olduğu sonucuna varılmıştır.

Authors: Arslan Mustafa Sedat , Besoluk Kamil
Published: August 2023

The aim of this study was to determine the effects of alone and combined treatment of Tarantula cubensis alcoholic extract (TCAE) and Methenolone Enanthate (ME) on morphometric parameters of humerus and femur in young rats. In this study, 36 five–week–old Wistar Albino rats were used. The animals were divided into 4 groups; Control group (n:6, normal saline solution, 0.2 mL·rat-1, subcutaneously –SC–), TCAE group (Tarantula cubensis alcoholic extract, 0.2 mL·rat-1, SC), ME group (Methenolone Enanthate), 10 mg·kg-1, intramuscularly –IM–) and TCAE + ME group (Tarantula cubensis alcoholic extract, 0.2 mL·rat-1, SC + Methenolone Enanthate, 10 mg·kg-1, IM). Drug treatments were done once a week for 7 weeks. At the end of the experiment, all the animals were euthanized and their humerus and femur bones were resected and their morphometric parameters were determined. No statistical differences were determined (P>0.05) between the groups in terms of the anatomical reference points (length, corpus thickness, cavum medullare diameter, and cortex thickness) of humerus and femur bones. In conclusion, it was found that alone and combined treatments of Tarantula cubensis alcoholic extract and ME (at normal dose) had no effects on morphometric parameters of humerus and femur bones in rats in the growing period. However, these effects may not be observed at high–dose and long–term treatments in rats.

This study aimed to screen the phenolic profile, antimicrobial and antiradical activities of endophytic fungi residing in the tissues of Acacia nilotica grown in Sudan. Isolates of endophytic fungi were isolated from fruit, leaf and twig. Methanolic extracts were prepared by maceration. Antimicrobial activity was determined by the disc diffusion method. Antiradical activity was evaluated by the 1, 1-diphenyl-2-picryl hydrazyl (DPPH) assay. Ten endophytic fungi were recovered from the twig (6), leaf (2) and fruit (2) of A. nilotica. Extracts revealed better antifungal activity, with isolates T3, L1 and F1 exerting the highest inhibition zones (20.6, 20 and 18.3 mm, respectively) against Aspergillus niger. Isolates T4 and T5 revealed the highest antiradical effect with IC50 values of 302 and 478 µg/mL respectively. Chemical analysis revealed that gallic acid and naringenin were the dominant compounds. Their pattern divided the endophytic fungi into two categories; gallic acid- rich endophytes including isolates L1 and L2 (isolated from the leaf) as well as isolates T4 and T2 (isolated from the twig). The other category was naringenin- rich endophytes comprised isolates F1 and F2, which were isolated from the fruit, and isolates T1, T3, T5 and T6 isolated from the twig. Moreover, extracts accumulated gallic acid were devoid of naringenin and the opposite was true. This behavior was not detected in the host plant where these two compounds coexist and identified in all extracts.

Este estudo tem como objetivo apresentar os efeitos da Biodança como forma de reduzir os níveis de estresse e ansiedade em acadêmicos de Educação Física. Trata-se de um estudo quase-experimental, com desenho pré-teste/pós-teste. Participaram da pesquisa alunos do curso de Educação Física da Universidade Estadual do Maranhão. Os participantes responderam um questionário validado para avaliação dos níveis de ansiedade e estresse que foram aplicados antes e após as intervenções de Biodança. Participaram da intervenção 13 alunos com média de 20 ± 2 anos de idade, sendo 7 (53,8%) do sexo feminino. A ansiedade estado não apresentou diferença significativa mas obteve um médio efeito pós intervenções (valor=0,52). A ansiedade traço não mostrou diferença significativa e apresentou um pequeno efeito (valor=0,24). Com relação ao estresse, também não observou-se diferença significativa e o efeito foi pequeno (valor=0,03). Conclui-se que os níveis de ansiedade e estresse dos acadêmicos mantiveram-se em níveis semelhantes aos do início da intervenção com a Biodança. O curto prazo das intervenções pode ter contribuído para a pouca mudança nos níveis de estresse e ansiedade.
