Published: March 2023

Information regarding the effects of the novel coronavirus on human reproduction is currently limited. The objective of our work was to assess whether, in women who have passed the disease, there was a variation in the ovarian reserve through the determination of AMH levels. During May-June 2020, women performing an Assisted Reproductive treatment and who had a positive IgG for SARS-CoV-2 were included in the study; this group of women had a previous AMH determination of no more than 6 months. Women were stratified into two groups, according to their previous AMH levels: low responders (AMH<1 ng/ml) or normal-high responders (AMH ≥ 1 ng/ml) Statistical analyses were performed using the Statistical Package for Social Sciences 19.0 (IBM Corporation, Armonk, NY, USA). A total of 46 patients were included in the study; 16 women were diagnosed as having low ovarian reserve (AMH < 1 ng/ml), with an average age of 38.6 years, whereas 30 were classified as having normal ovarian reserve (AMH ≥ 1 ng/ml), with an average age of 34.7 years. Generally, the data show no variation in AMH levels before and after SARS-CoV-2 infection (1.73 ng/ml vs. 1.61 ng/ml, respectively). However, when we analyzed these differences according to the study groups, the results were consistent with the patient's ovarian status. It is possible to conclude that the fact of having passed the disease does not affect the ovarian reserve status but the degree of the variation of AMH levels depending on the patient was a low or high responder.

Influenza B myositis is a self-limited process that is typically accompanied by myalgia and muscle weakness, which can be caused by an acute respiratory infection. It occurs in the convalescence phase of the disease. It can usually affect preschool and school children, who present bilateral pain and tenderness in the muscle groups of the lower limbs without alterations in the neurological examination. Being able to generate an alteration in the brand or bipedestation. Its main complication is rhabdomyolysis. In Guatemala is difficult to test for viral respiratory infection and the incidence of viral myositis is unknown, for which we consider the report important because it presents a benign course and is easy to manage with the use of non-steroidal anti-inflammatory drugs, to avoid unnecessary hospitalizations. We present to case report to an 8-year-old male patient, previously healthy, with diagnostic de Influenza B myositis.

Published: March 2023

The cases of antibiotic resistance in Enterobacteriaceae are of great global concern. This study aimed at contributing towards the fight against antibiotic resistance and ameliorate the management/treatment of Enterobacteriaceae-linked diseases. Ten (10) rectal swab samples were collected from five (5) male and five (5) females and two isolates were identified from the samples collected. The isolates were identified through colonial, morphological and biochemical tests carried out following standard procedures. Isolates were investigated for their antibiotic resistance profile, Multiple Antibiotic Resistance indices (MARi), pathogenicity and their resistance genes were identified through molecular means using plasmid amplification and primers. Primers used include. ermB, BlaTem, qnrB genes Result obtained showed the isolates to be Escherichia coli and Klebsiella oxytoca. E. coli showed Alpha (α) heamolysis, while Klebsiella oxytoca showed gamma (γ) heamolysis . E. coli was resistant to 75% of the antibiotics used, Klebsiella oxytoca was sensitive to 42% of all the antibiotics. All the test organisms were resistant to all classes of Cephalosporins. The plasmid profiling revealed that all isolates have low molecular weight plasmids. The molecular fingerprinting of the isolates using gene primers viz -a viz ermB, BlaTem, qnrB genes showed E. coli to have resistance genes for macrolides (ermB gene) while none of the isolates had resistance factor against quinolones (qnrB gene). This study showed a high carriage of Enterobacteriaceae having phenotypic resistance with corresponding plasmid-borne resistance genes. The need to understand how bacteria adapt to the antibiotic environment will lead to new therapeutic strategies for antibiotic-resistant infections. Interventions measures to minimize the abundance of antibiotic-resistant commensals and opportunistic pathogens may include faecal microbiota transplantation and the use of live biotherapeutics.
Increasing plant resistance with silicon applications
Authors: Domenico Prisa
Published: March 2023

The mineral element silicon, accumulated in the leaves and roots of various plants, plays a crucial role in increasing resistance to various biotic and abiotic stresses. Although considered a mineral element that is not essential for plant life, silicon provides significant benefits. This mineral accumulated in tissues provides increased resistance of cells to mechanical stresses, reduced water loss through transpiration, increased resistance to sunlight, and reduced metal toxicity and salt stresses. Plants accumulate silicon differently, depending on their root type and functionality. Molecular studies have made it possible to identify the genes responsible for silicon accumulation. In the future, advances in this field could improve techniques for studying the mechanisms involved in silicon uptake, not only by increasing its availability within tissues but also by improving its storage capacity. Unfortunately, many plants cannot absorb silicon and, therefore, cannot benefit from the mechanisms that lead to increased resistance to various biotic and abiotic stresses. This review aims to highlight the benefits obtainable with the use of silicon in those plants capable of absorbing it, particularly in the control of biotic and abiotic stresses.

Desmoid tumors are extremely rare. They represent 3% of all soft tissue tumors. Giant desmoid tumors are rarely reported in the literature and are a challenge in their therapeutic management. The radiological evaluation of extension allowed to delimit its extension in depth and its limits of exeresis. In our case, the tumor was surgically resected with simple postoperative care. This case illustrates the difficulties of managing this entity given its large size.
De Lula a Bolsonaro: rupturas e continuidades discursivas na política externa brasileira para os BRICS (2003 - 2020)
Authors: Silva André Luiz Reis da , Holleben Raquel de
Published: March 2023

Diante das transformações matriciais da política externa brasileira nos últimos anos, o objetivo do presente trabalho é analisar as rupturas e continuidades discursivas na política externa brasileira para o BRICS (Brasil, Rússia, China, Índia, África do Sul). A metodologia empregada consiste na análise dos pronunciamentos do governo Brasileiro na Assembléia Geral da Organização das Nações Unidas (AGNU) e nas Cúpulas dos BRICS, bem como análise das declarações finais das referidas cúpulas. Concluiu-se que houve um afastamento brasileiro da defesa do multilateralismo, da cooperação sul-sul e da multipolaridade, distanciando sua agenda externa dos demais países emergentes do BRICS e evidenciando que a matriz de inserção internacional do Brasil nos governos de Michel Temer (2016 - 2018) e Jair Bolsonaro (desde 2019) é diferente daquela vigente nos governos de Lula da Silva (2003-2010) e Dilma Rousseff (2011-2016).

Historical Gardens in Cinema: Location, Transformation, Image
Authors:   Russian State University for the Humanities, SOKOLOV BORIS M.
Published: March 2023

The article explores the roles of historical gardens in Western cinema. A garden can make a historical location (Versailles), mimic another historical garden (Vaux-le-Vicomte as Chantilly in Vatel), embody a national way of life (gardens of the National Trust in the 1995 TV series Pride and Prejudice), or be an abstract, to a greater or lesser extent, setting. In Atonement, the historical garden becomes a symbol, and in films about space (Silent Running) and the inner world metaphysics (The Fountain), the garden is reduced to a cultural archetype—a patch of turf, a spring, an old tree. One of the ways of utilizing the garden theme is its ironic presentation: the historical garden is shown as a ridiculous formal extravagance (The Draughtsman’s Contract) or as a costly project destroying the natural environment and the very life of the customer (The Serpent’s Kiss). The most intricate work with the theme of historical gardens was performed by Alain Resnais in Last Year at Marienbad. The nature for it was filmed in two Munich parks, and the formal interiors of Schleissheim Palace, with its countless mirrors, and the Rococo floral decor of the Amalienburg pavilion are continued in the views of the formal garden, which the director called “carved in stone.” A sculptural group, which the characters encounter in different parts of the park, represents their emotional states and existence on the border between reality and sleep. The conclusion is drawn that means. Among them are different levels of mediating documentary reality, utilization of cultural archetypes, and using the garden as a symbolic space.

Authors: ÇALIŞKAN YILMAZ Filiz , ÖZGENEL Mustafa
Published: March 2023

Uncertainty, competition, and changes in needs arising from developments in the fields of globalization, science, and technology affect not only for-profit organizations but also schools providing education services. Since schools are expected to be effective in this challenging situation, agile leadership characteristics are searched on school managers. The purpose of the study was to see if school administrators' agile leadership attributes predicted school effectiveness, and it was conducted using the relational survey model. Data is collected by 605 public school teachers in Istanbul from 2020 to 2021 with School Effectiveness Index and Marmara Agile Leadership Scale. While the prominent findings do not create a significant difference in agile leadership perceptions according to teachers' gender, education level, seniority, and age, they create a significant difference according to school levels. While school effectiveness perceived by teachers does not show great differences based on their gender or amount of education. It has been determined that there are considerable differences according to the school levels, ages, and seniority of the teachers. Finally, it was found that school administrators' agile leadership characteristics predicted school effectiveness in a positive and significant way.

Authors:   Korean Association of Agricultural and Food Policy, Kim Se-Hyuk , Kim Hyun , Kim Tae-Kyun
Published: March 2023

The purpose of this study is to analyze the factors affecting the satisfaction of urban to rural migrants. The satisfaction of urban to rural migrants was divided into two factors, economic satisfaction and life satisfaction. A nationwide survey of 466 urban to rural migrants was conducted and a seemingly unrelated bivariate ordered probit model was estimated. The results show that the factors affecting economic satisfaction are economic motivation, migration with family, having debt, affinity with neighbors, time to participate in agricultural education, number of participation in local activities, and satisfaction with living expenses. The factors affecting life satisfaction are economic motivation, having debt, number of participation in local activities, satisfaction with living expenses, relationship with neighbors, and family support. The results also indicate that the increase in annual income improves economic and living satisfaction. The results of this study may contribute more implications and useful information to the government’s policy for urban to rural migration.
An Analysis of the Linder Effect on Food Trade
Authors:   Korean Association of Agricultural and Food Policy, Cho Gue Dae , Lee Seung Geun , Kim Yoon Hyung
Published: March 2023

Recently, consumers’ interest in food safety has increased rapidly, and it may affect consumer preference and the food production process. Considering that high-income countries have stricter regulations on food production and greater consumer preferences for safe food products, countries’income level might have an important role in determining the quality of food products. Therefore, higher-income countries have possibly been exporting their food products to similar-income-level countries because of the greater consumer preference for safer food products. In this paper, we examine how income similarity between countries affects the trade flow of food products using a large-panel data set covering 2000 to 2018. We found that income similarity has an important role in the trade of food products and the Linder effect is larger than in the other industries we consider in this study. These results support the Linder hypothesis and imply that we need to consider income similarity an important variable in future research in food trade and when establishing a food exporting strategy.

South Africa is a leading destination for ecotourism. The establishment of ecotourism projects in South Africa - as is the case with most of the world - has been associated with geographically remote rural spaces located in the peripheral regions of the tourism space economy. This paper directs attention to the progress of an urban ecotourism destination in South Africa, namely Dinokeng in the Tshwane metropolitan area which is centred around the city of Pretoria. Dinokeng is distinguished by the fact that it hosts a Big Five game reserve in a metropolitan area. The research is based on stakeholder interviews conducted with 27 accommodation providers. The present study is original for its subject focus on urban ecotourism and by offering stakeholder perspectives on the emergence, progress and challenges of this ecotourism destination as a vital dimension of tourism change occurring in the Global South.
Effect of Al5Ti1B Grain Refiner and Al10Sr Modifier on Mechanical Properties and Corrosion Behavior of A360 Alloy
Authors: KOCAMAN Engin , ŞİRİN Selçuk
Published: March 2023

In this study, the effect of Al5Ti1B grain refiners and Al10Sr modifiers on the mechanical and corrosion properties of the A360 aluminum alloy was investigated. For this purpose, varying amounts of Al5Ti1B grain refiner and Al10Sr modifier were added to the molten A360 alloy and the molten metal was poured into a per-manent mold. Subsequently, microstructural investigations, hardness test, tensile strength and corrosion resistance of the samples were examined. The results showed that, the Al5Ti1B grain refiner promotes finer-grained and coaxial solidifi-cation. The Al10Sr modifier, broke down the eutectic particles in the microstruc-ture and caused a more homogeneous distribution in the structure. While the tensile strength and corrosion resistance of the alloy increased both the grain refiner and the modifier added to the A360 alloy, a slight decrease in hardness was observed in the alloys to which only the modifier was added.
Materials for the flora of Uzhgorod city based on herbarium analysis Uzhhorod National University
Authors:   State Higher Educational Institution «Uzhhorod National University», Soyma M.
Published: March 2023

The herbarium collection of the Uzhhorod National University (Herbarium UU), both the main collection of the flora of Transcarpathia, and the doublet collections of A. Margittai and L. Wagner are very interesting in the regional sense and have both scientific and historical and cultural significance. The herbarium of the Department of Botany of the Uzhhorod National University (UU) was established in 1947. Today, it is stored in the Botanical Garden and has about 107,000 herbarium specimens [4]. The personal collections of L. Wagner and A. Margittai are stored separately. The herbarium collection of the Uzhgorod National University covers mainly the territory of the Ukrainian Carpathians and the Prytisyan lowland and is currently the most complete herbarium collection of the flora of Transcarpathia. In particular, specimens of many species of aboriginal flora are kept in the herbarium, and the collection of regional exotics is particularly interesting. As a result of the analysis of the herbarium materials of the Department of Botany of the Uzhhorod National University, it was established that 469 species were recorded from the territory of the city of Uzhhorod. By the number of species, the families Brassicaceae, Asteraceae, Rosaceae, Fabaceae and Lamiaceae are the most numerous, Caryophyllaceae, Poaceae and Boraginaceae are much smaller. During the audit of the major part of the scientific herbarium of the Botany Department of UzhNU (flora of Transcarpathia), from all the herbarium specimens, those that were collected in the territory of the city of Uzhhorod or its surroundings, which are now included in the administrative boundaries of the city (for example, the villages of Domanyntsi, Dravtsi, Horyany, Radvanka, Radvansky forest, etc.) were selected. Among the found herbarium specimens are species that are now considered highly invasive within Ukraine. It is likely that for some of them the data refer to the first or one of the early findings of wildness (Amorpha fruticosa L., Robinia pseudoacacia L., Acer negundo L., etc.)

Authors: Mejía Rodríguez Gilberto
Published: March 2023

El objetivo de esta investigación es mejorar la comprensión del algoritmo de fidelidad variable y de diversos métodos de escalamiento a través de tres problemas. Los primeros dos problemas son analíticos, y el tercero es un problema de optimización structural. Los problemas han sido construidos especificamente para comprender el funcionamiento del algoritmo con modelos (alta y baja fidelidad) de diferente grado de no-linealidad y diferente número de variables de diseño. El rendimiento del algorimo al usar diversos métodos de escalamiento de primero y segundo orden (aditivo y multiplicativo), es comparado con el rendimiento de usar programación cuadrática secuencial solamente sobre el modelo de alta fidelidad. La principal contribución de esta investigación es la comprensión ganada con los problemas propuestos, lo cual puede extenderse a otros problemas, sobre el alcance y limitandes del algoritmo, y la elección del método de escalamiento más apropiado dependiendo del caso de studio que se tenga. Además, los resultados muestran como una reducción del tiempo de diseño puede obtenerse, mientras se reduce el número de evaluaciones al modelo de alta fidelidad y se alcanza convergencia.

Generación de certificados de registro basados en firmas agregadas
Authors: Quintanilla Machado Kyrna , López García María de Lourdes
Published: March 2023

La propiedad intelectual es un derecho de los autores para registrar sus creaciones artísticas. Tal derecho se obtiene con la generación de un certificado de registro que es avalado por tres entidades: Registrador, Secretario y Registrador Jefe. El procedimiento se realiza de forma manual, por lo cual es un proceso poco eficiente y presenta diversos problemas de seguridad como falsificaciones o firmas no autorizadas. En este trabajo es propuesto un protocolo seguro basado en firmas agregadas para la generación de un certificado de registro de una propiedad intelectual. El objetivo es producir un certificado que asegure que la firma de cada autoridad sea generada de acuerdo a una jerarquía. De tal manera que la autoridad de más alto rango pueda comprobar la validez de las firmas de las autoridades subordinadas, permitiendo un valor agregado a la certeza jurídica de los servicios ofrecidos por las oficinas de Propiedad Intelectual, así como, para los autores de las obras registradas.

Los dispositivos y computadoras embebidas con bajo consumo de energía se han vuelto una alternativa de bajo costo para aplicaciones de monitoreo de riesgos naturales, donde los datos son recolectados en tiempo real y son guardados, o transmitidos para procesamiento, como en el caso de volcán Popocatepetl. La precisión en colores sigue siendo un problema porla velocidad de procesamiento limitada en equipo embebido, tal como esta ilustrado en los experimentos de este trabajo, donde los espacios de color clásicos y precisos en forma perceptual, típicamente usados en equipos de escritorio, no son aptos para tales tareas. Sin embargo, las alternativas recientemente introducidas muestran potencial, proveyendo balance entre desempeño en tiempo real y precisión. Resultados experimentales con pruebas de desempeño corriendo en aparatos embebidos están descritos en este trabajo, proveyendo fundamentos fuertes para las alternativas propuestas.

The multimodal emotion perception in codependent individuals
Authors: Portnova Galina V , Stebakova Daria A
Published: March 2023

The emotional disturbances of individuals with codependency are often ignored. This study aimed to investigate the emotional perception of codependent individuals in four modalities – visual, auditory, tactile and olfactory. An EEG study was performed and presented pleasant and unpleasant stimuli selected by a panel of experts for each modality. Participants (fifteen codependent individuals and fifteen healthy volunteers) were instructed to assess the emotional impact and pleasantness of stimuli. The method of EEG spaces was used to visualize how close perceived stimuli were according to EEG data. The results showed ambivalence of emotional response to emotional stimuli with social component and lack of recognition of emotional tone detected in EEG and behavioral levels. The empathy feeling in codependent individuals was detected for fewer emotional stimuli. The group differences were associated with evolutionary newer modalities (auditory and visual). The lack of emotional perception in codependent subjects was determined by social factors and was detected in visual and auditory modalities, which were more involved in social interactions than olfactory and tactile modalities.
Diary null subjects in L2 English: A study on grammatical acceptability
Authors:   Universitatea din București, Sevcenco Anca
Published: March 2023

The current paper investigates the grammatical acceptability of null subjects in the diary register of L2 English by intermediate and advanced students, L1 speakers of Romanian. Overall results indicate performance that does not surpass chance level, and therefore, a strong conservative preference for overtly realized subjects in diary contexts. However, individual analysis has identified a small group of L2 learners who consistenly scored well above chance in the four experimental conditions (overt subject, null subject in root clause, null subject in embedded clause and null subject in yes-no questions). I discuss several factors that relate to the difficulty L2 learners have with accepting on-target null subjects in the diary register. Quite likely, they never had enough exposure to the relevant input. L2 acquisition slows down when multiple grammars (core and non-core) are identified. Also, subject omission is optional, so the study tested a preference, not a mandatory phenomenon.
Taboo ritual in Spanish: A study of pragmatic strategies
Authors:   University of Lodz, Urbaniak Ewa
Published: March 2023

"The aim of the present paper is to analyse the pragmatic structures that constitute the taboo ritual in Spanish colloquial conversations. The analysis is based on the assumption that, in the modern Spanish society, some of the topics are considered taboo and while speaking about them, a special ritual is required. I claim that this ritual is based on some pragmatic strategies that present important meanings and interactive functions. In order to confirm my hypothesis, a number of Spanish colloquial conversations are examined. By identifying the taboo topics and observing how they are introduced to the conversation, I present the pragmatic mechanisms that create the taboo ritual in modern Spanish."
Romanian aspectual verbs and the causative alternation
Authors:   Universitatea din București, Lăcătuș Elena
Published: March 2023

The aim of the present paper is to investigate the control/raising behaviour of Romanian aspectual verbs. Following Mourounas & Williamson’s (2019) proposal for English aspectuals, I show that in Romanian these verbs enter the causative alternation, a property which distinguishes them from both raising and control verbs and which can explain their hybrid behaviour. The aspectual verbs which merge with an infinitive and a subjunctive complement evince raising-like behaviour in their anticausative variant and control-like behaviour in their causative variant. Their anticausative variant is not marked and the verb does not project any Voice Phrase. In their causative variant, they project a thematic Voice Phrase which hosts an external argument, assigned an Agent-Initiator theta-role. Some of the verbs in the termina ‘finish’ class have a marked anticausative variant which projects an expletive Voice Phrase (Schäfer 2008) which hosts the voice marker se whose presence signals the existence of a volitional, external argument in the structure. When these verbs occur with a supine complement they can only have an unmarked form, indicative of causative status, and they behave exclusively like verbs of control.

However, North Korean still maintains the basic or core values within the change of leadership eras. The core values are defined below:a.Ethnocentrism (Leader Descendants and Societies) b.Classless Societyc.Feudalismd.Capitalisme.Society levels grant the services and treatments (Family Classes)f.Family history and revolutionary or unrevolutionary origing.Strict and Territorial; not all citizens can have the nation facilitiesh.The highest ranking people in North Korea are Kim Il Sung's family and relativesi.Mythical leaders; North Korea's ruling dynasty has always cast itself as somewhat supernaturalj.Difficult adjustments; such limited access to the world, North Koreans who do make it out often struggle to adjust. Some are paranoid, a skill that served them well at home where anyone could turn anyone else in to the police for saying the wrong thingk.Music is a diplomatic tool
Photochemistry of RNA, RNA Monomers, and Plausible Prebiotic Precursors

Sunlight is the primary source of energy to promote change on Earth. In this context, ultraviolet radiation can be thought as a catalyst of chemical change to refine chemical feedstocks and facilitate their transformations into the building blocks of life. To establish reasonable environmental constraints for the chemical origins of life, it is central to understand how thephotochemical reactivity or photochemical resistance of prebiotic molecules might have supported the formation of the RNA monomers on the Earth’s surface and particularly in aqueous solution. In this chapter, the photochemistry of the RNA monomers and several conceivably importantprebiotic precursors are reviewed. The emphasis is on delineating the primary electronic relaxation or photochemical reaction pathways that may have enabled the accumulation and the selection of the RNA monomers as the building blocks of life during prebiotic times. Finally, the moderatelyinvestigated photochemistry of RNA is summarized and contrasted to that of DNA. It is surmised that the enhanced structural rigidity and the increased excitation delocalization length in RNA may have conspired during prebiotic times for RNA oligomers to prosper under the otherwise harsh ultraviolet radiation conditions of early Earth.
ENTREPRENEURSHIP BUSINESS FEASIBILITY STUDY (STUDI KELAYAKAN USAHA)
Authors: Sardi Ahmed
Published: March 2023

Since somebody is planning to launch and operate a firm, they must do a business feasibility study. Researching in-depth is done at this point. A business feasibility study can be helpful to a firm since it determines whether or not a business strategy is feasible, as the name implies. Business feasibility studies are not randomly conducted. Business owners need to be aware of the objectives, stages, and aspects.Generally, a business or business feasibility study is research that concerns various aspects, be it from legal, socioeconomic and cultural aspects, market and marketing aspects, technical and technological aspects to management and financial aspects, where it is all used for the basis of feasibility study research and the results are used to make decisions whether a project or business can be done or postponed and even not carried out.In accordance with the future conditions are filled with uncertainty, certain considerations are needed in starting a business, where the basis of these considerations can be obtained through a study of various aspects of the feasibility of a business to be run, so that the results of the study are used to decide whether a project or business should be feasible to do or postpone or even cancel. The above is to show that the feasibility study will involve many teams of various experts according to their respective fields or aspects such as economists, law, psychologists, accountants, technology engineers and so on.

Experimental replication of stone tools is an important method for understanding the context and production of prehistoric technologies. In scientific undertakings, experimental control is a valuable and necessary means of ensuring that confounding variables are not influencing the outcomes of the study. One way that researchers can exert control in knapping experiments is to standardize the type, form, and size of raw materials that are provided to the knappers. Though measures to standardize materials are already part of archaeological practice, specific protocols, let alone comparisons between standardization techniques, are rarely openly reported. Consequently, independent laboratories often repeat the same trial-and-error process for selecting the ‘right’ material for testing. We investigate a variety of techniques and raw materials (e.g., hand-knapped flint, machine-cut basalt, manufactured glass, and porcelain). Each material was evaluated for their validity, reliability, and ease of standardization. Here, we have outlined the raw material tests we performed, providing information on the individual approaches, as well as comparisons between the techniques and materials according to both validity and reliability, along with their costs and our own recommendations. This text is intended as a serviceable guide on raw material standardization for knapping experiments, including previously pursued avenues and means that are as-of-yet undescribed in the experimental archaeology literature. We include additional considerations for techniques that were not included in this study or which are presently not widely available and/or affordable. Future potential in this field would benefit from advances in the relevant technologies and in methodological approaches.
Cancer Risk Factors: Genetic, Environmental, and Lifestyle

Genetic factors: Some people are born with certain genetic mutations thatincrease their risk of developing cancer. For example, women with mutations inthe BRCA1 or BRCA2 genes have a significantly higher risk of developing breastand ovarian cancer. Genetic testing can help identify these mutations, which canbe useful for identifying people who may benefit from increased cancer screeningor other preventative measures.
At What Age Can Children Initiate and Execute a Mutually Beneficial Exchange?

Using a novel exchange paradigm, we demonstrate that Australian pre-school children from middle to high socio-economic backgrounds may be capable of executing a mutually beneficial exchange. In Study 1, 3- to 5-year-old children completed a tower building task, in which they were given an opportunity to make trading choices via pre-set options that could allow both them and a puppet to succeed. A majority of children across age groups selected the efficient trade option over other alternatives. In Study 2, we modified the task to have less structure. With no pre-set options, 5-year-old children initiated an efficient exchange to a greater extent than younger children. A different task that relied on distributing desirable vs. less desirable rewards (stickers) revealed a complementary pattern. The two studies shed light on the onset and developmental trajectory of a pre-requisite skill for negotiation: children’s capacity to initiate and execute a mutually beneficial deal, varying across different task contexts.

The multitude of definitions, models, and measures of positive mental health has hindered definitional precision and therefore the ongoing scientific evolution of this important area. This review aimed to synthesize the theoretical and measurement landscape of positive mental health. We extracted measures capturing umbrella concepts of positive and adaptive states of mental health (i.e., well-being, quality of life, and resilience/coping), the underlying dimensions (e.g., vitality, autonomy) and design features (e.g., response scales). Our search identified 155 measures of positive mental health with a total of 410 constituent dimensions. Using thematic analysis, we consolidated these 410 original dimensions into a set of 21 themes. These themes were transformed into a concept map to illustrate their inter-relationship with the umbrella concepts of positive mental health. Our results demonstrate minimal consensus on the underlying dimensions and measurement approaches for investigating positive mental health, resulting in an unwieldy situation for ongoing scientific study.
