Children typically prefer to attend to social stimuli (e.g. faces, smiles) over non-social stimuli (e.g. natural scene, household objects). This preference for social stimuli is believed to be an essential building block for later social skills and healthy social development. Preference for social stimuli are typically measured using either passive viewing or instrumental choice paradigms, but not both. Since these paradigms likely tap into different mechanisms, the current study addresses this gap by administering both of these paradigms on an overlapping sample. In this study, we use a preferential looking task and an instrumental choice task to measure preference for social stimuli in 3–9 year old typically developing children. Children spent longer looking at social stimuli in the preferential looking task but did not show a similar preference for social rewards on the instrumental choice task. Task performance in these two paradigms were not correlated. Social skills were found to be positively related to the preference for social rewards on the choice task. This study points to putatively different mechanisms underlying the preference for social stimuli, and highlights the importance of choice of paradigms in measuring this construct.

Authors: Li Mingjun , Pan Jiangyang , Liu Yaolai , Wang Yazhou , Zhang Wenchuan , Wang Junxing
Published: June 2022

A hybrid model integrating chaos theory, support vector machine (SVM) and the difference evolution grey wolf optimization (DEGWO) algorithm is developed to analyze and predict dam deformation. Firstly, the chaotic characteristics of the dam deformation time series will be identified, mainly using the Lyapunov exponent method, the correlation dimension method and the kolmogorov entropy method. Secondly, the hybrid model is established for dam deformation forecasting. Taking SVM as the core, the deformation time series is reconstructed in phase space to determine the input variables of SVM, and the GWO algorithm is improved to realize the optimization of SVM parameters. Prior to this, the effectiveness of DEGWO algorithm based on the fusion of the difference evolution (DE) and GWO algorithm has been verified by 15 sets of test functions in CEC 2005. Finally, take the actual monitoring displacement of Jinping I super-high arch dam as examples. The engineering application examples show that the PSR-SVM-DEGWO model established performs better in terms of fitting and prediction accuracy compared with existing models.
The Answer Bot Effect (ABE): A powerful new form of influence made possible by intelligent personal assistants and search engines
Authors: Epstein Robert , Lee Vivian , Mohr Roger , Zankich Vanessa R.
Published: June 2022

We introduce and quantify a relatively new form of influence: the Answer Bot Effect (ABE). In a 2015 report in PNAS, researchers demonstrated the power that biased search results have to shift opinions and voting preferences without people’s knowledge–by up to 80% in some demographic groups. They labeled this phenomenon the Search Engine Manipulation Effect (SEME), speculating that its power derives from the high level of trust people have in algorithmically-generated content. We now describe three experiments with a total of 1,736 US participants conducted to determine to what extent giving users “the answer”–either via an answer box at the top of a page of search results or via a vocal reply to a question posed to an intelligent personal assistant (IPA)–might also impact opinions and votes. Participants were first given basic information about two candidates running for prime minister of Australia (this, in order to assure that participants were “undecided”), then asked questions about their voting preferences, then given answers to questions they posed about the candidates–either with answer boxes or with vocal answers on an Alexa simulator–and then asked again about their voting preferences. The experiments were controlled, randomized, double-blind, and counterbalanced. Experiments 1 and 2 demonstrated that answer boxes can shift voting preferences by as much as 38.6% and that the appearance of an answer box can reduce search times and clicks on search results. Experiment 3 demonstrated that even a single question-and-answer interaction on an IPA can shift voting preferences by more than 40%. Multiple questions posed to an IPA leading to answers that all have the same bias can shift voting preferences by more than 65%. Simple masking procedures still produced large opinion shifts while reducing awareness of bias to close to zero. ABE poses a serious threat to both democracy and human autonomy because (a) it produces large shifts in opinions and voting preferences with little or no user awareness, (b) it is an ephemeral form of influence that leaves no paper trail, and (c) worldwide, it is controlled almost exclusively by just four American tech companies. ABE will become a greater threat as people increasingly rely on IPAs for answers.

Published: June 2022

Introduction

Operative vaginal delivery is the use of forceps or vacuum devices to assist the eligible laboring mother to avoid poor birth outcomes. It is associated with increased maternal, neonatal morbidity and perinatal complications if it is not used appropriately. Instrumental delivery use needs health care providers’ skills, knowledge, and decision-making ability for good maternal outcomes.

Objective

This study aimed to assess immediate unfavorable birth outcomes and associated factors of operative vaginal delivery among women delivered in East Gojjam Zone Public Hospitals, North West Ethiopia.

Method

The study design was institution based cross-sectional and consecutive sampling procedure was used to select 313 mothers in the study, from March 1, 2019, to April 30, 2019. We used Epi data version 3.1 for data entry and SPSS version 25 software for cleaning and analysis. A Bivariable logistic regression analysis was used to identify the association between each outcome variable and each factor. Again, a multivariable logistic regression analysis was employed to identify factors associated with each outcome variable, and variables with a p-value less than 0.05 were taken as significant variables.

Results

The overall unfavorable maternal outcomes of operative vaginal delivery were found to be 32.9% [95% CI: 27.8, 38.3]. No formal education (AOR = 8.36; 95% CI: 1.01, 69.2), rural residence (AOR: 11.77; 95% CI: 2.02, 68.41), male sex of the neonate (AOR: 2.87; 95% CI: 1.08, 7.61) and zero station during instrumental application (AOR: 6.93; 95% CI: 1.75, 27.5) were factors associated with unfavorable maternal outcomes. The study also showed that the magnitude of unfavorable neonatal outcomes was 34.8% (95% CI: 29.7, 40.3). Vaginal first-degree tear (AOR = 0.03, 95% CI: 0.001, 0.951) and blood transfusion (AOR = 7.38, 95% CI: 1.18–46.15) was statistically significant factors associated with unfavorable neonatal outcomes.

Conclusion

The overall unfavorable maternal and neonatal outcomes of operative vaginal delivery were high compared with some other studies done in Ethiopia.

Published: June 2022

In My Shoes is a peer supported, teacher-led, school-based intervention that aims to improve the school participation and connectedness of students on the autism spectrum. The aim of this study was to explore the feasibility, fidelity, and preliminary effectiveness of In My Shoes in mainstream elementary schools. Ten Grade 3 and 4 students on the autism spectrum and 200 of their typically developing peers across eight classrooms and six schools participated. The following aspects of feasibility were explored: recruitment capability and sample characteristics, data collection procedures and outcome measures, appropriateness, implementation, and practicality of the intervention. Fidelity was explored by evaluating the delivery of intervention components against set criteria. Preliminary effectiveness was investigated by evaluating changes in intervention outcomes pre-post intervention using a range of outcome measures. Study findings are encouraging, suggesting In My Shoes is a feasible and appropriate intervention, and shows promise in improving the self-report school engagement of all student participants, as well the classroom participation and subjective school experiences of students on the autism spectrum. Useful insights into ways the intervention and the design of future research can be improved are discussed.
Deadly serious: Pandemic humour, media and critical perspectives
Authors: Bernal Victoria
Published: June 2022

COVID-19 is the most mediated pandemic in history thus far. COVID-19 humour, much of it circulated online, is a global phenomenon, but it takes different forms in different settings. This Special Issue brings together articles that add to our understanding of how Africans have experienced corona pandemic conditions, as well as contributing to the scholarship on media in African contexts, while focusing on humour. I suggest that we understand humorous responses to the COVID-19 crisis as discourses on contemporary conditions, and a means of highlighting the ongoing crises that precede the pandemic and contribute to the impact of the virus. In that sense, humour can be quite serious.
The why of humour during a crisis: An exploration of COVID-19 memes in South Africa and Zimbabwe
Authors: Msimanga Mbongeni Jonny , Tshuma Lungile Augustine , Matsilele Trust
Published: June 2022

This article inquires why humour flourishes in face of tragedy. Memes, as we argue, give people a sense of power as they offer commentary that critiques and mocks the government policies and ineptness, simultaneously offering a sense of hope and relief in face of the pandemic. With a focus on the COVID-19 pandemic, this study probed the nature, character and the why of humour in two southern African countries: South Africa and Zimbabwe. Findings show that memes were used to comment on lockdown regulations and speak against public authorities, to raise awareness of COVID-19 and expose poor health delivery systems. Our findings show that memes in South and Zimbabwe were used to bring dialogue about the COVID-19 pandemic and communicate health-related issues.
Satirical realities in COVID-19 humour: A Critical Discourse Analysis of Nigerian Facebook posts
Authors: Onwubiko Chioma Deborah
Published: June 2022

Coronavirus popularly known as COVID-19 is a pandemic that stormed the globe and rendered strong nations helpless and even the world powers, powerless. Initially, the Nigerian government was reluctant to put measures in place or lock its borders until a returnee was diagnosed after he had infected some people. This necessitated several measures including total lockdown, social distancing and improved personal hygiene to forestall its spread. Moreover, Nigerians believe that the state of the nation is even worse than this pandemic and, thus, have developed mastery, especially via satire in weathering any kind of storm. It is therefore, not surprising that the Facebook has become a veritable platform where Nigerians evoke humour while exposing human foibles in their linguistic disposition, with the intention to improve the society. This study, therefore, examined the satirical devices in the Facebook posts of Nigerians with the aim of teasing out the ideologies portrayed in relation to the existing social, economic and political attitude of the people towards the pandemic. Consequently, 22 Facebook posts were purposively selected for analysis, drawing input from Horatian’s approach to satire and sociocultural approach to Critical Discourse Analysis. The analysis reveals various satirical elements deployed as a subtle and effective alternative to contest power abuse, social injustice and propagate change. The study also reveals the wittiness and absurdity of satire that makes it a ready tool to unbridle people’s feelings; laden with different ideologies with the aim of relaxing tension and catalysing transformation in the society. Moreover, the import of weathering the storm becomes bare as an essential make-up of Nigerians; the tinge of humour intended in the posts relieves perceived tension and reminds the readers to take life easy, thus, making the study quite engaging.
Observação dos Ventos. Sociedade - Direito (2010-2022)
Authors: Cunha Paulo Ferreira da
Published: June 2022

Observação dos Ventos fala por si. É uma reunião de reflexões cuidadosamente maturadas e apresentadas ao leitor como exercício a um tempo o pedagógico e ordenador do pensamento. (...) Paulo Ferreira da Cunha é um autor sobremaneira conhecido, com uma obra multifacetada e profunda. Em boa hora decidiu reunir estas oportunas prosas. No livro que tenho o gosto de prefaciar, apresenta-nos, ao ritmo da relação com o grande público, uma observação atenta dos tempos e dos seus sinais, ilustrando para os dias de hoje o que os gregos designaram por “paideia” e os latinos como “humanitas”. A aprendizagem é o cerne da vida, o que nos obriga a olhar o mundo sob múltiplos ângulos e perspetivas. E, como diz o nosso autor, o discurso “não é tanto sobre o desconcerto do mundo, que parece transparecer de alguns diagnósticos mais sombrios. É sobre a imensa vontade e energia para poder tornar a terra habitável; no caso, não falando de habitabilidade ecológica (que é fundamental e pressuposto, porque implicando a própria Vida) mas da salubridade do espírito, nas suas dimensões mais diversas”. Do Prefácio, de Guilherme D’Oliveira Martins.

Published: June 2022

Molares severamente inclinados em posição mesial causam problemas periodontais e desarmonias na oclusão. Em algumas situações, é indicado que sejam verticalizados, ainda que em posição desfavorável, para restauração da saúde periodontal e balanceio da oclusão sem a necessidade de reabilitação protética. O objetivo do presente trabalho é descrever a verticalização, por meio de ancoragem esquelética, de um terceiro molar inferior mesioinclinado na região posterior do lado direito da mandíbula. Previamente, o paciente havia sido submetido à extração do primeiro molar inferior e apresentava reabsorções apicais externas generalizadas. A ancoragem máxima foi realizada em dois locais diferentes e em duas etapas. A primeira etapa consistiu na instalação de dispositivo de ancoragem no ramo mandibular, em posição distal ao dente impactado. A segunda etapa consistiu na instalação de mini-implante no espaço intra-alveolar entre o segundo molar e o segundo pré-molar do mesmo lado e utilização de cantiléver de TMA. O planejamento adequado do recurso de ancoragem possibilitou a verticalização do dente #48 sob controle biomecânico dos efeitos colaterais, de maneira simples e de fácil ativação. Ao fim do tratamento, foi devolvida a harmonia à oclusão e preservadas as estruturas dentoalveolares.

Optimization of light intensity and color temperature in the cultivation of Chlorella vulgaris culture using the Surface Response Method
Authors: Christwardana Marcelinus , Hadiyanto H. , Pratiwi Wahyu Zuli
Published: June 2022

Microalgae have an important role as a source of biomass in producing energy. One type of microalgae that has the potential to be developed is Chlorella vulgaris. Several factors that affect the growth and biomass production of Chlorella vulgaris microalgae are color temperature and light intensity because they play an important role in the photosynthesis process. This study aims to influence the effect of light and color temperature and optimize these parameters using Response Surface Methodology (RSM). Two independent variables were varied: light intensity 200, 400, 600, 800, 1000 lux and color temperature 3000, 4000, 5000, and 6000 K. The results showed that the average value of Chlorella vulgaris growth was higher along with higher light intensity. At a color temperature of 4000 K, the highest biomass yield and the most negligible biomass production were found at 6000 K. At a color temperature of 4000 K, it is feasible to apply it as an alternative lighting source in the production of Chlorella vulgaris. The combination of light intensity and color temperature shows that the specific growth rate and doubling time have opposite trends where high values produce low values and vice versa. Growth in dark conditions, the specific growth rate was 0.0026 day-1, and the optimal light intensity at 600 lux treatment. ANOVA evaluation showed that color temperature greatly affected growth. Based on the optimization, the optimal specific growth rate of 00751day-1 with the conditions of light intensity and color temperature of 556 lux and 4152 K, respectively.
Depreciation deduction mechanism being in use in the fishing industry and intended for sustainable development of the region
Authors: Vasilenko Marina E.
Published: June 2022

In recent years, there has been a stabilization of the country's economy, which in the future is a major prerequisite for increasing demand for measures to limit the catch and import of raw fish abroad. They should lead to a reorientation of enterprises towards deep processing of raw fish, which will require the inflow of significant investment resources into the industry. In fact, the problem of fixed assets depreciation accounting is not new; there are several methods of their regulation in the modern world, but it is not enough when solving different managerial tasks. The relevance of the problem is due to the discrepancy between tax and accounting, between international financial reporting and Russian standards, as well as between the need to obtain an adequate and accurate assessment of the safety, and usefulness of fixed assets in the production process. As a result, the purpose of this study is to investigate modern methods of accounting depreciation of fixed assets and to identify ways to eliminate overdue areas of this problem. At the correct picked up system harmoniously working at the enterprise, and timely replacement of obsolete non-current assets, the enterprise can achieve the best productivity results and increase its liquidity.
Monetary policy and banking intermediation in CBDC economy
Authors: Leonov Mikhail Vitalyevich
Published: June 2022

Increased dissemination of information and communication technologies in the economy has led many central bankers around the world to consider the introduction of money in the digital form. In academic literature, various central bank digital currency (CBDC) issues from technical design to political influence are discussed, although until now it has not been fully implemented in any country except the Bahamas. The central bank digital currency (CBDC) is an additional form of national currency that combines the properties of cash and bank accounts. This study mainly aims to provide a comprehensive analysis of monetary policy in the CBDC economy. to meet the aim of the study, the study applies an agent-based model that has six types of economic agents and complicated interaction algorithms. The various design parameters are employed to study the dynamics of endogenous variables. Model simulations suggest that CBDC introduction leads to reduced macroeconomic volatility and price stability. Furthermore, the study provides evidence of the increased efficiency of the interest rate channel of the monetary policy transmission mechanism and the negative consequences of possible banking disintermediation. Based on the results obtained, the study concludes that the CBDC impact the economy through changes in the monetary base, strengthening the structural liquidity deficit, banking disintermediation, and increasing the fiscal policy capabilities. The proposed agent-based model provides a theoretical foundation for the further study of monetary policy and banking intermediation in the CBDC economy.

Authors: Zoriktuevna Aiusheeva Irina , Vladimirovna Soyfer Tatiana
Published: June 2022

In digitalization, trust is a necessary factor in economic and social development in general that determines the content of public relations and ensures their positive effect. In sharing economy, due to the specifics of the emerging relations, the issue of creating a digital environment of trust is especially relevant. The objective of the research is to determine the directions for improving the mechanism of civil law regulation of certain aspects of the collective use of goods and services, including studying the possibilities of the influence of the main provisions of civil law on the provision of the necessary trust between the turnover participants; research on the transformation of legal institutions, including the protection of reputation, in the context of digitalization processes; establishment of the specifics of regulating relations on the use of blockchain and other latest technologies aimed at creating and increasing the level of digital trust in collaborative consumption of various assets. The main research methods are deduction (the study of general legal provisions and their application to some regions of collaborative consumption), induction (the study of the rules for organizing the work of specific Internet platforms in the sharing economy and the subsequent allocation of general principles). Based on the results, the effective development of the sharing economy in digitalization presupposes a high level of trust, which has several interrelated manifestations that require differentiated approaches to their legal support. In addition to trust in digital technologies and services, the security of remotely performed transactions, and the preservation of the confidentiality of personal data, trust in society is essential for the sharing economy since only those who trust are trusted.
Emotional approach to fitness club brand design
Authors: Belokovalenko Oksana , Tkhorikov Boris
Published: June 2022

Public demand in recent decades for healthy lifestyles, improving its quality and preservation of active longevity has found an echo in the form of the dynamic development of the global fitness industry. Our country is no exception and since the 1990's, domestic fitness has made a rapid spurt from zero position: according to the national community of professional participants of sport and fitness industry, fitness in Russia engages regularly up to 7 million people. The paper presents the author's statement of possible scenarios for the development of the fitness industry highlighting the factors that can transform consumer demands in post-covid economy. The hypothesis is put forward that the competitiveness and economic stability of fitness clubs in the medium term will be determined by the level of customer retention rate and by increasing their loyalty, the effective formation of which is possible by stimulating through marketing communications a positive mental and emotional response in target audiences to the potential and actual satisfaction of certain primary biological needs through fitness services. To prove the hypothesis the corresponding methodology of fitness club brand design based on the emotional approach of M. Lindstrom and K. Roberts was developed. Its verification and testing was carried out. The results obtained testify to the correctness of the author's statements and actualize the continuation of research in the field of emotional branding.

Comparing motivational features between feedback givers and receivers in English speaking class
Authors: Su Wei
Published: June 2022

In peer feedback literature, the topic of motivation for feedback is not sufficiently explored, and attention to motivational differences between feedback givers and receivers unbalanced. To address this gap, the present study tracked motivational changes of Chinese students performing consecutively the roles of written-feedback givers and of receivers over eight weeks in their English-speaking class. It employed motivation questionnaires and students’ personal letters to collect their perceptions of each role. The results showed that students generally displayed stronger motivation at the giver role than at the receiver role. In particular, their motivation scores of the communicativeness dimension were significantly different between the two roles because this dimension could easily stimulate their sense of fulfilment and critical thinking when giving feedback. By comparison, for the dimensions of peer accountability and class enjoyment, the students reported similarly modest levels of motivation at both roles because they deemed peer accountability and class enjoyment as sources of extrinsic stimulation and less sustainable than the communicativeness dimension.
Magnetic tuning of liquid crystal dielectric metasurfaces
Authors: Izdebskaya Yana V. , Yang Ziwei , Liu Mingkai , Choi Duk-Yong , Komar Andrei , Neshev Dragomir N. , Shadrivov Ilya V.
Published: June 2022

Dielectric metasurfaces hold an exceptional potential for the next generation of tunable optical systems that find applications in sensing, ranging, and imaging. Here, we introduce and demonstrate magnetic field tuning of dielectric metasurfaces infiltrated with liquid crystals. To illustrate this concept, we show how the reorientation of liquid crystal induced by the magnetic field changes the spectrum of the resonant dielectric metasurface. This new magnetic-field tuning approach offers significant advantages over other liquid crystal tuning methods since it does not require pre-alignment or the fabrication of structured electrodes, which are both challenging when dealing with metasurfaces. Furthermore, there are no strict limitations on the thickness of liquid crystal cells. Importantly, our approach allows for gradual tuning of the resonances by changing the magnetic-field orientation and, thereby, shows good promise for highly tunable optical metadevices.

El objetivo de este estudio fue explorar la asociación entre perfil de personalidad, droga de impacto y estatus de egreso en pacientes con trastornos por uso de sustancias. El desistimiento del tratamiento de las adicciones es alto, por lo que es relevante dar seguimiento de las deserciones para conocer sus causas. Se revisaron 300 expedientes clínicos de pacientes internados en un centro de rehabilitación y, a partir del cuestionario de evaluación de variables sociodemográficas, psicológicas y de salud, se elaboró una base de datos con las variables de interés. Para el análisis se utilizó el procedimiento de análisis de correspondencias. Entre los principales hallazgos se encontró que el perfil esquizoide presentó mayor frecuencia de consumo de alcohol, mientras que el perfil antisocial y esquizotípico presentó mayor frecuencia de consumo de marihuana. A seis meses del egreso, los pacientes con perfil paranoide y narcisista tuvieron mayor frecuencia de abstinencia.
Fell points from Merín Lagoon, Uruguay: new data and their relevance to the peopling of south-eastern South America
Authors: Nami Hugo G.
Published: June 2022

The dating and routes by which humans colonised South America continue to be debated. Recent research in Uruguay has yielded new Palaeoindian lithic finds from the southern shores of the coastal Merín Lagoon. The author's analysis of a group of Fell points—comparable to other regional examples—shows that this widespread artefact was produced using locally available materials and that they were repeatedly resharpened and repaired until no longer functional. The finds from the Merín Lagoon permit consideration of changing sea levels and their influence on colonisation routes, resource exploitation and archaeological preservation. The Atlantic coastline may have been one possible route of entry for early colonisers of South America.
Destination-Specific and Home Environment Condom Norms Influence Sexual Behavior During Travel

Published: June 2022

Travelers may adapt HIV risk-reduction practices based on perceived destination-specific norms. We examined the association between perceived condom norms and condomless anal sex (CAS) during international and domestic travel and in the home environment among men who have sex with men. Men who traveled internationally in the past 12 months were recruited by respondent-driven sampling (N = 501). Not knowing destination-specific condom norms was significantly associated with less CAS during international travel and in the home environment but not during domestic travel. Perceiving home environment condom norms to expect use of condoms was significantly associated with less CAS during domestic but not international travel. Men were less likely to engage in CAS during international travel when destination-specific condom norms were unknown. Unfamiliarity with the environment and culture may influence some men to refrain from higher-risk behaviors. During domestic travel, some men appeared to apply home environment condom norms, which may be erroneous in some situations and pose an HIV risk.
Persistent suicidal ideation in a large intensive outpatient adolescent population sample: A preliminary report on the role of sleep disturbance
Authors: Gazor Afsoon , Brown William David , Naqvi S. Kamal , Kennard Beth , Stewart Sunita
Published: June 2022

Sleep disturbance is a unique, yet understudied, risk factor for suicidal thoughts and behaviors (STBs). The present study sought to explore the relationship between suicidal ideation (SI) and self-reported sleep disturbance in a sample of adolescents in an intensive outpatient program targeting suicidality (N = 691). Analyses conducted include paired samples t tests, multiple linear regression, and analysis of variance to examine group differences in sleep disturbance over time. Sleep disturbance and SI were associated at each timepoint, and sleep disturbance at admission predicted SI at discharge. Those with the most severe SI at discharge indicated increased sleep disturbance relative to admission, whereas those reporting no SI at discharge nearly resolved all sleep difficulties. Future studies should utilize objective sleep measures, longitudinal assessments, and include a more diverse sample to better inform the relationship of sleep and SI. These findings suggest that directly managing sleep disturbance during treatment could decrease the risk of STBs.
“Call Me by Your Name”: The Wrong Action: From Ferenczi to Enactment as a Process
Authors: Riefolo Giuseppe
Published: June 2022

It is always hard for psychoanalysis to connect free associations and action. With Freud, action could be interpreted only when it referred to the transference; otherwise, action was a resistance to the possibility of free association. Unlike Freud, Ferenczi recognized the importance of the analyst's acting-out as the patient's unconscious request for experiences of trauma to be mobilized. By presenting a clinical case, the author offers the analyst's error as the mobilization of a traumatic block. The error activates a “Process of enactment,” whereas if the error is not considered positively, it is simply a mistake, or the loss of a creative opportunity.

Species can survive periods of unfavorable conditions in small areas that are protected from climate-related disturbances, such as increasing temperature and severe drought. These areas are known as “microrefugia” and are increasingly recognized by conservationists. Although some studies suggest that the in situ survival of invertebrate species may be mediated by topographically complex environments, there is little information about the main environmental factors that drive species distributions within such areas. Here, we investigate the spatial patterns and species trait composition (moisture preference, body size, dispersal capacity, and feeding habit) of five groups of ground-dwelling arthropods—spiders, woodlice, ants, ground beetles, and rove beetles—in topographic depressions (i.e., “solution dolines” or “solution sinkholes”) and on the surrounding plateau within a forested karst landscape and analyze the microhabitat conditions that affect these arthropod assemblages. We found that dolines have the capacity to maintain characteristic arthropod assemblages—including species that may be particularly vulnerable to climate change (e.g., species associated with moist habitats)—and thus, they may contribute to the landscape-scale biodiversity of karst landscapes. We also found that doline bottoms have the potential to maintain permanently moist conditions not only in spring and autumn but also during drier periods of the year. This ability of dolines may indicate the presence of potential hydrologic microrefugia. Furthermore, dolines displayed specific sets of species traits (e.g., more small-bodied spiders, more carnivorous ground beetles, and more rove beetles with high dispersal capacity occurred in dolines than on the plateau), highlighting that they may facilitate the persistence of some species and traits that are purged from the surrounding landscape. Future studies may reveal the long-term ecological consequences of different climatic and anthropogenic factors on the distribution and functional traits of arthropod taxa within microrefugia and on the refugial capacity of these safe havens under a warming climate.

Published: June 2022

A reevaluation of the late Miocene (early late Hemphillian) megalonychid fossils found at San Gerardo de Limoncito, Coto Brus Valley, Costa Rica is presented. These specimens which had previously been referred to Pliometanastes cf. P. protistus, based on a partial mandible and associated teeth material are now considered to belong to the genus Zacatzontli, previously only known from the late Miocene of Mexico and here reported for the first time from Costa Rica. The material is considered to be a new species of Zacatzontli based on a comparison with the type and other members of the Megalonychidae from the Hemphillian of North America as Zacatzontli tecolotlanensis, Pliometanastes protistus and Megalonyx spp.

Petrografía de la cerámica prehispanica fina (550/600-800 d.C.): Esfera Cerámica Canbalam, costa peninsular de Campeche y Yucatán, México
Authors: Obando Luis G. , Jiménez Socorro Del Pilar
Published: June 2022

El concepto de pasta fina está incluido dentro de la “Esfera Cerámica Canbalam”, ha sido interpretada culturalmente, como una corriente pancostera del Golfo de México. Este estudio se realizó con el fin de contribuir al concepto de pasta fina desde el punto de vista petrológico, utilizando la herramienta de la petrografía cerámica. Se analizaron 15 láminas delgadas de cuatro sitios costeros en la península de Yucatán: Isla Piedras, Uaymil, Jaina y Xcambó. La clasificación se realizó con el criterio tipológico seguido de la petrografía microscópica, basado en eso, se define por primera vez “pasta fina” como aquella pasta, que al ser observada al microscopio petrográfico polarizante, está compuesta por una matriz arcillosa y cuyos componentes detríticos promedio son de arena muy fina, y la fracción más gruesa puede ser de hasta un 10 %, la cual oscila entre arena media hasta arena gruesa. Como tecnología de manufactura, se propone el uso de los carbonatos como fundentes.

Published: June 2022

La Red Sismológica Nacional (RSN) localizó 3745 sismos locales durante el año 2021, lo cual es equivalente a la energía sísmica liberada por un evento de magnitud (Mw) 6,9. La sismicidad se localizó principalmente en siete zonas con 50-350 temblores. Hubo 209 sismos (~6% del total) sentidos por la población, incluyendo 31 con Mw entre 5,0 y 6,7. La mayoría de estos sismos fueron superficiales (~88% < 30 km), de magnitud baja (~52% Mw < 3,9) y fueron originados en fallas de las placas Caribe y Panamá (~69%). El sismo mayor del año, de Mw 6,7, se originó en la Zona de Fractura de Panamá, sin generar daños ni víctimas. Todos los sismos de Mw ≥ 5,5 tuvieron sus epicentros mar adentro y alejados de centros de población por lo que no se reportaron intensidades altas.

Apples and oranges in the basket of a clinical model for exercise addiction: Rebuttal to Brevers et al. (2022)
Authors: Szabo Attila , Dinardi Jacob S , Egorov Alexei Y
Published: June 2022

This note is a reply to Brevers et al.’s (2022) the commentary. We first explain that the commentary's title is in discord with the theoretical implications of the Expanded Interactional Model of Exercise Addiction (EIMEA; Dinardi et al., 2021). Subsequently, we argue that in contrast to Brevers et al.’s arguments, exercise volume or intensive physical exercise is not even mentioned in the revised EIMEA. Most importantly, we point out that the commentary's reference to assessment scales of exercise addiction is irrelevant, because the EIMEA is intended for idiographic clinical cases rather than nomothetic research. Furthermore, we discuss how the ELMEA cannot account for secondary exercise addiction and motivational incentives due to its individual-specific orientation. Finally, we conclude our reply by highlighting that Brevers et al.’s commentary seems to revolve around nomothetic research assessing a certain level of ‘risk’ of exercise addiction, while the EIMEA accounts for specific clinically dysfunctional cases presented in the limited number of case studies published in the literature.
Chronic wounds in the elderly: Decubitus, leg ulcers, and ulcers of rare aetiology
Authors: Bánvölgyi A. , Görög A. , Gadó K. , Holló P.
Published: June 2022

The ageing processes, primarily after the age of 60, bring about a number of important changes that affect the skin’s protective function. These changes directly and indirectly increase its vulnerability and impair its ability to heal. Hence, the incidence of chronic wounds increases in the elderly population. Dry skin, often accompanied by itching and consequent scratching, can lead to the development of wounds. The skin’s ability to regenerate itself is also impaired by the atrophy that affects all the three layers of the skin, the epidermis, dermis, and subcutis. The deterioration of vascularisation and innervation increases the chance of ulcer formation and impaired healing of existing wounds. Together these lead to the development of chronic lower limb ulcers in elderly patients or decubitus in older bedridden patients. Bedsores are more likely to develop in older patients with reduced body weight due to their decreased amount of adipose tissue capable of pressure-relieving. This latter negative tendency may be exacerbated by the presence of reduced mobility, impaired muscle strength, and frequent incontinence. In all respects, the propensity to heal is worse than in younger age, thus in many cases a chronic process is expected, and in some cases halting the progression may be a significant outcome. Ulcers of rare aetiology can occur at any age, so pyoderma gangrenosum, vasculitis, and other ulcers with rare aetiology in the elderly population should also be considered.
