The Diamond Ratio: A Visual Indicator of the Extent of Heterogeneity in Meta-Analysis
Authors: Cairns Maxwell , Cumming Geoff , Calin-Jageman Robert , Prendergast Luke A.
Published: August 2020

The result of a meta-analysis is conventionally pictured in the forest plot as a diamond, whose length is the 95% confidence interval (CI) for the summary measure of interest. The Diamond Ratio (DR) is the ratio of the length of the diamond given by a random effects meta-analysis to that given by a fixed effect meta-analysis. The DR is a simple visual indicator of the extent of heterogeneity in the meta-analysis, where increasing values of DR greater than 1.0 indicate increasing heterogeneity. We investigate the properties of the DR, and its relationship to four conventional but more complex measures of heterogeneity. We propose for the first time a CI on the DR, and show that it performs well in terms of coverage. We provide example code to calculate the DR and its CI, and to show these in a forest plot. We conclude that the DR is a useful indicator that can assist students and researchers to understand heterogeneity, and to appreciate its extent in particular cases.
The significance of anxiety symptoms in predicting psychosocial functioning across borderline personality traits
Authors: Howard Jacqueline , De Jesús-Romero Robinson , Peipert Allison , Riley Tennisha N. , Rutter Lauren A. , Lorenzo-Luaces Lorenzo
Published: August 2020

Emotion regulation is a central task of daily life. Difficulty regulating emotions is a core feature of borderline personality disorder (BPD), one of the most common and impairing personality disorder diagnoses. While anger and symptoms of depression are instantiated in the criteria for BPD, anxiety is not, despite being among the mostcommon psychiatric symptoms. We explored the interactions between anxiety symptoms and BPD traits in predicting well-being (WHO-5) as well as poorer work and social adjustment (WSAS), in a sample of online respondents (N = 471) while controlling for anger and depression. We hypothesized that anxiety would lead to more impairment (i.e., lower well-being and poorer work and social adjustment) as BPD traits increased. BPD traits and symptoms of anxiety both contributed to overall lower levels well-being and higher levels of psychosocial dysfunction. However, contrary to our expectations, at higher (vs. lower) levels of BPD traits, symptoms of anxiety did not contribute to lower well-being on the WHO-5. For the WSAS, there was no consistent evidence for an interaction between BPD traits and anxiety in predicting functioning. By and large, our results do not support the idea that anxiety contributes to more impairment at higher levels of BPD traits.
Out of bounds? The boundary specification problem for centrality in psychological networks
Authors: Neal Zachary P. , Neal Jennifer Watling
Published: August 2020

The analysis of psychological networks has become common in multiple subfields including clinical, social, and personality psychology, where the focus is often on identifying highly central nodes that represent symptoms, beliefs, or traits. However, the boundaries of these networks are often ambiguous and relevant nodes are often missing from the network. In this paper, we use a series of simulations to show that even under typical conditions of missingness, the centrality of nodes in an empirical psychological network are poorly correlated or uncorrelated with their centrality in a hypothetical `true' psychological network, and thus are invalid. We illustrate the implications of this lack of validity using an empirical example drawn from a recent study of political belief system networks, demonstrating that the original study would have drawn incorrect conclusions about American's most central political beliefs. We conclude by recommending that centrality measures should be computed and interpreted only in psychological networks that include (nearly) all the nodes inside a theoretically meaningful boundary.
A new perspective from time use research on the effects of lockdown on COVID-19 behavioral infection risk
Authors: Gershuny Jonathan , Sullivan Oriel , Sevilla Almudena , Vega-Rapun Marga , Foliano Francesca , de Grignon Juana Lamote , Harms Teresa , Walthery Pierre
Published: August 2020

We present findings from the first two waves of an innovative, population-representative, UK time-use diary survey conducted both pre- and mid-lockdown, using an online diary instrument that proved both reliable and quick-to-field. Combining diary information on activity, location, and co-presence to estimate infection risks associated with daily behavior, we show clear changes in such behavior related to infection risk between the pre and mid-lockdown periods: a substantial reduction of time spent in those behaviors with the highest levels of risk, accompanied by an equivalent increase in low-risk behavior. Because, in general, a populations’ time use changes relatively slowly, the behavioral changes revealed may be interpreted directly as a consequence of the UK COVID-19 ‘lockdown’ regulations. Subsequent waves will reveal the behavioral consequences of future changes in regulation

Trawl has the size a mesh size  a small size pockets of the cod end. This allows the trawl fishing gear to potentially be a fishing gear that is not selective about the size of the fish and the species that are targeted for its catch. If this fishing gear is left, its existence will eventually have a negative impact on the sustainability of fish resources, especially in coastal waters. The purpose of this study is to calculate the composition and proportion of main catches, bycatch and discarded catches. It is expected that knowing the composition and proportion of the main, by-product and discarded catches can provide an overview of the pressure on stocks and sustainability of fisheries resources in the waters where trawl is operated. The method used in this study is a survey method. A series of survey activities were carried out directly in the field to identify and count the types of species caught by trawlers. Based on the percentage of main catch, by-catch and discard per type, it Matuta planipes are the dominant species caught by trawlers (23.65%). The main catch Parapenaeus longirostris 15.92%. In addition, the main catch caught were Parapenaeopsis sculptilis (9.787%), Penaeus merguiensis (0.646%), Metapenaeus brevicornis (10.118%), Penaeus indicus (0.029%) and Squilla mantis (0.153%). Percentage of bycatch reaches 2.245% of 10 species caught and discarded catches reach 61.103% of 25 species caught.
Transjugular intrahepatic portosystemic shunt for the treatment of refractory ascites: A population-based cohort study
Authors: Mah Jeffrey M , Djerboua Maya , Groome Patti A , Booth Christopher M , Flemming Jennifer A
Published: August 2020

BACKGROUND: Randomized trials have shown that transjugular intrahepatic portosystemic shunt (TIPS) improves control of ascites compared with serial large volume paracentesis (LVP) in patients with refractory ascites. However, the effect of TIPS on liver transplant-free (LTF) survival is controversial. Our objective was to compare TIPS versus serial LVP on LTF survival in the general population of patients with refractory ascites. METHODS: This is a retrospective, population-based cohort study using linked administrative health data from Ontario, Canada. Adult patients identified with refractory ascites from January 1, 2008 to December 31, 2016 were included and followed until December 31, 2017. A propensity score was used to match patients treated with serial LVP to those who received TIPS in a 2:1 ratio. LTF survival was evaluated using Kaplan–Meier analysis and Cox proportional hazards regression with TIPS treated as a time-varying exposure. RESULTS: Overall, 4,935 patients with refractory ascites were identified and 488 patients were matched (325 serial LVP, 163 TIPS). The mean age was 58 years, 70% were male, 50% had viral hepatitis, the median model for end-stage liver disease (MELD) score was 12, 13% received liver transplant and the 1-year LTF survival was 72%. After TIPS, 80 patients (49%) had no further requirement for LVP by 6 months and 61 patients (37%) never required a repeat paracentesis. In survival analysis, there was marginally worse LTF survival in patients receiving TIPS (TIPS HR 1.29, 95% CI 1.00–1.67; p = .052). CONCLUSION: In this population-based study of patients with refractory ascites, TIPS was associated with improved control of ascites but not improved LTF survival.

Postoperative cognitive dysfunction develops in the early and persists in the late postoperative period. Clinically, this condition manifests itself in the form of memory impairment, violation of concentration and violation of other higher functions of the cerebral cortex. The aim of this study is to study cognitive function in patients who underwent surgery with the use of general anesthesia in a remote period in a month.According to the results of the MMSE test, in the middle-aged patients the dynamics of the deterioration of the cognitive function was observed to a lesser degree than in the young patients, which is probably related to the age-related features of the plasticity of the cognitive function. In patients of middle age, according to the results of the FAB scale, at this period of the study was at the same level as those in young patients, which is associated with the age specificity of the plasticity of the cognitive function. According to the test drawing hours, there was no significant difference in the recovery rate, it was gradual, but no complete restoration was observed. For the 10-word memory test and the Schulte trial, the recovery was gradual, with a full recovery of the indicator to the level before the operation.

Published: August 2020

Two different gas-liquid flow behavior downstream a double helical swirl element inside a vertical pipe was observed in our preliminary experiment. The present Computational Fluid Dynamics (CFD) study confirms that the dynamics of gas-liquid flows inside the swirl separator is highly influenced by the liquid superficial velocity. The separation behavior in this work at a liquid superficial velocity of 0.1 m/s was the worst both axially and radially since the gas core cannot be sustained up to the outlet. The separation condition was improved by the increase of the liquid superficial velocity. The best separation condition in this study was achieved at the liquid superficial velocity of 1.0 m/s where the dense gas core can be maintained up to the outlet.

Por uma educação não transfóbica: reconhecimento e produção de verdades trans na educação
Authors: Torres Marco Antonio , Gonzaga Modesto Rubens , Martins da Costa de Menezes Thaynara
Published: August 2020

Os relatos de pessoas trans sobre educação têm exposto insuficiências da formação docente que precisam ser problematizadas. No presente artigo analisamos como o discurso transfóbico impede ou dificulta extremamente a produção de inteligibilidade de formas de existência para além da cisheteronormatividade. Nossos diálogos teóricos foram realizados a partir de Judith Butler e Michel Foucault, bem como autoras trans que analisam o contexto escolar. Estas, com suas experiências, mobilizam e desenham transformações de regimes de verdade bem como podem contribuir no combate do discurso transfóbico. Por fim, destacamos um desafio posto à formação docente: aprender a deixar em aberto nossas definições sobre as sexualidades, abrindo-se às autodefinições de pessoas trans. Desse modo, nos propomos ao exercício de aprender com autoras trans sobre uma educação não transfóbica, de aprender como suas experiências podem produzir posições críticas no contexto da formação docente.

O presente ensaio se propõe a pensar as relações de gênero e aspectos da diversidade sexual a partir das contribuições de um episódio televisivo, um texto de Eve Sedgwick e outro de Giancarlo Cornejo: enunciações em torno dos meninos efeminados. Postulamos que nos debruçarmos sobre as “crianças viadas” pode nos ajudar a compreender as hierarquias de gênero que provocam e sustentam as assimetrias entre distintas posições. Assim, a partir desse analisador, interroga-se a escola e a formação de professores e professoras para pensarmos como nos posicionarmos frente a essas crianças como expressões da diferença.
Docência nas fronteiras: quilombo, raça e gênero
Authors: Miranda Shirley Aparecida
Published: August 2020

Os quilombos no Brasil consistem no mais evidente mecanismo de enfrentamento ao sistema escravista, emblema da resistência coletiva que constitui a diáspora africana. Em 2012 foram publicadas as diretrizes curriculares nacionais para a educação escolar quilombola. As recomendações e desafios dessa modalidade de educação dirigem-se às professoras. Poderíamos falar então em uma docência quilombola? Esse artigo discute essa indagação a partir das narrativas de quatro professoras que se reconhecem quilombolas, se autodeclaram negras e atuam em escolas situadas nos territórios onde vivem. Seguimos nas trilhas das narrativas para evidenciar quem são e como se formaram docentes quilombolas e que deslocamentos produzem para a relação entre gênero e docência. O artigo está organizado em cinco tópicos. Após a introdução, discutimos os percalços da formação docente das professoras entrevistadas. No terceiro tópico refletimos sobre a relação gênero e raça e as desestabilizações que propõem a uma análise da profissão docente. No tópico seguinte, situamos as fronteiras em que constroem a docência quilombola e palavras finais
Teachers’ primary concerns in a case of educational innovation introduction in primary schools in Greece
Authors: Psaras Dr. Charalabos
Published: August 2020

By converting all-day primary schools of suburban and urban areas in Greece into schools that implement the Comprehensive Reformed Educational Programme (CREP), a set of innovations were implemented, significantly altering the Greek school. The purpose of this study was to investigate the effect of selected variables over concerns of teachers who work at such schools. Additionally, this research asked the teachers to identify the professional development support and interventions required to enable them to make better use of the Book-reading Advancement (Philanagnosia) Activities innovation. Teachers’ administrative and pedagogical guidance executives, based on the above, will design the necessary interventions to positively address teachers’ concerns and implement the specific innovation in the most effective manner. Overall, the study found that higher teacher concerns were task related, with a significant record of information and self-concerns, which may indicate that the introduction of the innovation was not properly designed to address teachers’ primary concerns.

The essential oil of basil (Ocimum basilicum L.) has high economic value and is produced in the plant by secondary metabolism. Its quantity and composition tend to vary as a response of the plant to stress situations due to changes in the environment and phenological phase. This work aimed to evaluate the development, the chemical composition, content, and the yield of essential oil of basil rich in Linalool, as a function of the soil water tensions and the harvest stages, in a loam texture soil. The experiment was carried out in a greenhouse and consisted of three harvest times (BF - beginning of flowering,  FF - full flowering,  and EF - end of flowering) and five values of soil water tension to define when to irrigate (20, 30, 40, 50, and 60 kPa), totalizing 15 treatments. The irrigation in the soil water tension of 60 kPa generated a reduction in the content and the yield of essential oils compared with 20 kPa, only in the FF harvest stage. However, it did not modify the composition of the essential oil. Regardless of the soil water tension to define irrigation, the highest levels and yields of essential oil were found in the EF harvest stage. Harvest stages did not change the composition of the essential oil or the content of Linalool. In turn, the contents of the components Cineol, Camphor, ∝-Terpeneol, and Isobornyl acetate increased with the harvesting period from BF to EF. Eugenol had the opposite trend, reducing the content from BF to EF. Linalool, a component in greater proportion in essential oil, showed a higher content in soil water tensions up to 50 kPa, decreasing only by 60 kPa. In loam textured soils, it is recommended that basil producers, who aim to extract Linalool, irrigate when the soil water tension reaches up to 50 kPa, with the harvest at any stage of flowering.

Background: The individual's personality and social factors influence a person's desire or ability to use assistive technology devices. Therefore, these components contribute to a positive or negative influence on the use of assistive technology and on the degree of satisfaction with the use.Objective: The aim of the study was to evaluate levels of satisfaction of individuals with physical disabilities with their prescribed piece of assistive technology. Methods: A quantitative questionnaire survey using The Quebec User Evaluation of Satisfaction with Assistive Technology 2.0. Data collect took place from August 2018 to April 2019, in the Physiotherapy Clinic of a Community University, in the Specialized Center for Physical and Intellectual Rehabilitation II and in the support networks for individuals with disabilities, such as: Roda Solta, Association for Supporting Families of Impaired People, Association of Disabled People and athletes of the women's Paralympic Handball Championship. Results: Fifty-six individuals with physical disabilities between 20 and 80 years old participated in the research, 27 women (48.2%) and 29 men (51.8%).The results suggested  that individuals are quite satisfied with their piece of assistive technology M=3.56(SD=1.09) and more or less satisfied with the professional services provided M=3.28 (SD=1.34). Among the 12 items considered most important by the participants, durability of the resource (54%) prevailed, followed by comfort (28%) and safety (24%).Conclusions: The dissatisfaction of individuals with physical disabilities was evident both in issues related to the resource and in the area related to the professional services, in relation to the resources. It needs to be adapted to the user’s needs, always aiming to improve health condition and quality of life.

People with autism spectrum disorder (ASD) have multifactorial etiology, combined by different factors, both genetic, psychological and environmental; however, it´s necessary sharply discriminate those significant factors or components, regarding elaborate an early action protocol for diagnostic processes and subsequent intervention guidelines, which co A total of 192 participants with ASD of three intensity levels (American Psychiatric Association -APA-, 2013) have collaborated in this study. ASD diagnostic shape the discrimination´ aim to 18 independent variables, considered, a priori, potentially influential over diagnostic intrinsic process.

Results of discriminant analysis include two axes it delimits the two main functions, represented by two variables: "karyotype" (Wilks´ Lambda statistic= .88) and "diagnosis" (Wilks´ Lambda statistic= .83). Both variables are complemented along structure matrix of discriminant analysis with variable "gene" for first function ("karyotype") and variable "age" to second function ("diagnosis" + "karyotype").

These allow defining the general characteristics to establish an effective action protocol for the specific diagnosis, which constitutes the general aim of this empirical research.

The amount of available information in the media grows continuously and, frequently, it does not have a basis in the scientific literature. In the area of ​​food and nutrition, the contents are available on social media profiles, websites and blogs, which usually appoint some foods as “superfoods” – able of curing diseases or inhibiting their development –  or, on the other hand, classifying other foods as the cause of damage to health. Kefir-based products can be classified in the first category, being considered a “superfood” by the media. Thus, the aim of this study is to search for information about kefir in digital media and to evaluate such information based on scientific articles. The contents were collected from 50 websites or blogs, using Google as a search tool. The data obtained were divided into 25 positive categories and 5 negative categories. One made a comparison with the scientific literature. Analyzing the information about kefir, the majority has a scientific basis, however, digital media put the research data in a superficial way, without clear information to readers.

Published: August 2020

Virtual learning environments (VLE) have frequently been used in educational practices, and the evaluation of their effectiveness as instruments to support learning gains must consider several dimensions. This paper presents an evaluation model for VLE, called MA-AVA (Model for the Evaluation of VLE), built after a review of the literature and focused on verifying students' learning gains. The MA-AVA evaluation model was applied in a pilot study to an undergraduate engineering class, using a VLE, Educ-MAS-GA, in the discipline of Analytical Geometry. The results indicate that, although students' perception of learning in VLE is relevant, the knowledge acquired is more subtle and difficult to assess. Therefore, a VLE learning evaluation model should include different dimensions of learning, such as the students’ perceptions and their measures of learning gain.
