Morality justifies motivated reasoning in the folk ethics of belief
Authors: Cusimano Corey , Lombrozo Tania
Published: July 2020

When faced with a dilemma between believing what is supported by an impartial assessment of the evidence (e.g., that one’s friend is guilty of a crime) and believing what would better fulfill a moral obligation (e.g., that the friend is innocent), people often believe in line with the latter. But is this how people think beliefs ought to be formed? We addressed this question across three studies and found that, across a diverse set of everyday situations, people treat moral considerations as legitimate grounds for believing propositions that are unsupported by objective, evidence-based reasoning. We further document two ways in which moral evaluations affect how people prescribe beliefs to others. First, the moral value of a belief affects the evidential threshold required to believe, such that morally good beliefs demand less evidence than morally bad beliefs. Second, people sometimes treat the moral value of a belief as an independent justification for belief, and so sometimes prescribe evidentially poor beliefs to others. Together these results show that, in the folk ethics of belief, morality can justify and demand motivated reasoning.

Authors: Southward Matthew W. , Wilson Anne C , Cheavens Jennifer S.
Published: July 2020

Objective: To develop more unified, process-based, and disseminable psychotherapy treatments, it is important to determine if there is consensus among therapists regarding intervention strategies. Design: Because emotion regulation is a cornerstone of modern treatments and a thriving area of clinical research, we assessed therapists’ ratings of the effectiveness of commonly studied emotion regulation strategies. Methods: Therapists (n = 582) read eleven vignettes describing stressful scenarios and rated the effectiveness of ten emotion regulation strategies in each scenario. Results: Across therapists, we found general consensus regarding the most (i.e., problem-solving) and least (i.e., concealing emotions) effective strategies. Cognitive/behavioral/third-wave therapists rated acceptance and distraction as more effective, and emotional expression and gathering information as less effective, than other therapists, Fs > 4.20, ps < .05, whereas hours of clinical experience were generally unrelated to strategy effectiveness ratings. Conclusions: We discuss what these points of agreement and relative disagreement among therapists reveal about a more unified, process-based treatment approach and how these results can guide emotion regulation research.
Multiple activities change intervention, a developing psychosocial tool for severe depression: initial report of cases
Authors: Agarwal Atul
Published: July 2020

Many depressed individuals are labelled as treatment resistant, refractory, or difficult to treat depression. Such depression is highly disruptive and leads to multiple adverse outcomes in a person’s life including marital turmoil, unstable employment, and early mortality. The so-called newer techniques, involving electricity or magnetism—are unproven, costly, not easily available, may lead to harm, and may require surgery and anaesthesia. With no effective treatment modality available, these cases of severe depression become significant, as they reported remarkable recovery with a novel psycho-social intervention called multiple activities change intervention or MACI. A 36-year man Kumar presented with severe depression of 15-years duration. At the time of presentation, he was faced with multiple physical and psychological symptoms, workplace difficulties, and domestic disharmony and violence. He had been taking selective-serotonin-reuptake-inhibitors and lorazepam, and his BDI-II score was 36. MACI was administered that led to sharp reduction in symptoms and other all-round improvements. BDI-II score fell to three, and all psycho-pharmaceuticals were gradually stopped. He stopped considering himself mentally ill. All this and more happened within a space of 100 days. Two other similar cases are being reported.

Published: July 2020

Spelling words accurately is not an easy process. Instead, it is a complex developmental skill. Due to this fact, several studies have recently investigated learners’ spelling ability and how this skill develops in different stages. The main purpose of this study is to examine the developmental nature of Saudi intermediate school students' acquisition of spelling knowledge as measured by the Schlagal's Qualitative Spelling Inventory (designed to assess spelling error patterns). Further, it aims at determining whether Saudi intermediate school students' spelling performance improves as their grade level increases or decreases based on word-level complexity or difficulty. In fact, this study is significant since it reflects the progress of Saudi intermediate school students not only in spelling, but in other literacy areas such as reading, and listening. A strong parallel has been found between spelling, reading and listening. The sample of the study was 300 participants, all of whom were 7th and 9th male graders who study at intermediate public schools in Riyadh, Saudi Arabia. Spelling features and word spelling scoring scales were used to score the given data. The findings showed that the 7th-grade students were listed at the phonetic stage, while the 9th-grade students were listed at the patterns within words stage and syllable juncture stage. Besides, the findings revealed that students' spelling performances improved as their grade level increased. Moreover, students' spelling performances were decreased with the increase of word-level difficulty or complexity.

Published: July 2020

The physics learning process at school does not involve students directly which causes the low cognitive learning outcomes of students. For this reason, it is necessary to apply an effective learning model for improving student learning outcomes. One suitable learning model is the treffinger learning model. The treffinger model provides learning activities with three stages namely basic tools, practice with the process, and working with real problems. These three stages can make students actively and creatively involved in the learning process. The purpose of this research is to find out the effectiveness of increasing cognitive learning outcomes of students on optical material by applying the Treffinger learning model. This type of research is a quasi-experimental design with a non-equivalent control group design. The research sample was taken two classes randomly as the experimental class and the control class from the student population in class XI IPA of SMA Negeri 9 Pekanbaru. The data collection instrument used students' cognitive learning achievement test consisting of pretest and posttest given to the experimental class and the control class. Data were analyzed using descriptive and inferential analysis. Descriptive analysis results obtained an average absorption capacity of 72.64% experimental class with a good learning category and 63.47% control class with quite a good category. With the results of the inferential analysis with an independent-sample t-test, there are significant differences in learning outcomes between the experimental class and the control class, where the experimental class has a higher increase in learning outcomes. Thus the use of the treffinger model is effective in improving student learning outcomes in class XI IPA of SMA Negeri 9 Pekanbaru on optical material.

The study aims to identify the role of the selected gastronomic trends in the Czech gastronomic establishments. The study highlights the key findings of quantitative and qualitative research provided with the focus on both the demand and the supply side. It is focusing on the dispute between guests’ opinions and entrepreneurs’ views based on few variables for gastronomic trends. Entrepreneurs’ and guests’ views in three Czech Regions were studied in one set with notes incorporated on possible mutual differences between them. The partial least squares variant of linear discriminant analysis (plsLDA) and partial least squares (PLS) was applied as they give a clear superiority due to both, interpretational and stability property. It was proven that the partial least squares variants lead to direct answers to questions in the studied field. Participation/organization of food festivals and slow food are positively related. The significant tasks emerge to a great extent covering differences between guests´ and entrepreneurs´ opinions. On the other hand, the connection of economic interest to gastronomic trends is relatively weak.

In Fortune Fair and Foul

This article focuses on the idiosyncratic conception of happiness Sir Kenelm Digby develops in the letters he wrote after the death of his wife in 1633. It contextualises Digby’s vision of happiness through an examination of the different traditions he revisits and appropriates to develop his personal and subjective ethics of self-care, mainly Renaissance Neoplatonism, the idealisation of conjugal love, the idealism of Italian poetry, and an ascetic model of widowhood linked to the tradition of spiritual mourning. It analyses how Digby’s conception of happiness, through its vindication of subjectivity and excess, challenges the early modern ethos of consolation and speculates on the reasons that may have led Digby to present his readers with such an extraordinary self-portrait.
La construcción social de la mujer en el cristianismo e islam
Authors: Vizcarra Tacca Alexis Francisco , Serruto Castillo Alison
Published: July 2020

El estudio analiza la posición de la mujer en la religión cristiana e islámica presentado elementos importantes de ambas doctrinas religiosas que se caracterizan por etiquetar y guiar la vida de las mujeres dentro de sus sociedades bajo el yugo patriarcal, lo cual conlleva el establecimiento de normas que tienden a determinar la construcción social de los hombres y mujeres en base a doctrinas eminentemente patriarcales. Así mediante el estudio realizado en base al método del análisis de contenido de los discursos escritos, se logró dilucidar las diferencias de ambos géneros en la dinámica social de ambas religiones, que fueron representadas por personajes que consideraban a la mujer como un ser inferior al hombre. Esta “inferioridad” se sustentaba en la aceptación de relatos expuestos en los libros sagrados de ambas doctrinas religiosas, que confluyen en la historia del “pecado original” al determinar que fue Eva la transgresora de la prohibición dada por Dios y su posterior incitación a Adán a caer en pecado. A partir de este relato bíblico que es considerado como un hecho real más allá de la imposibilidad de verificación, se somete a la mujer durante siglos al hombre siendo deshumanizada, hecho que en la actualidad aun presenta vestigios que se resisten a desaparecer a pesar de los movimientos sociales en pro de la igualdad de género en nuestras sociedades.

Abstract

Background: WHO reports that the prevalence of pregnant women with iron deficiency is around 35-75% and increases with increasing gestational age. This clearly raises the risk of maternal death, prematurity, low birth weight, and increased perinatal mortality.

Objective: To determine the effect of dates palm juice administration on the increase in hemoglobin levels in pregnant women.

Method: The experimental research design in this study was the One Group Pre-test and Post-test design. The population in this study were all TM III pregnant women in the Palangka Raya Midwife Independent Practice in January-March 2020. Samples were TM III pregnant women in January-March 2020 who met the inclusion and exclusion criteria of 27 respondents with consecutive sampling. The statistical test used is the Paired T-Test.

 Results: 21 people (70%) had high school education, aged 20-35 years (21%) (70%), and 30 people (> 23.5 cm) of lila size were 30 people (100%). There was a significant difference (p = 0.29). Conclusion: There is an effect of an increase in hemoglobin levels in TM III pregnant women after being given palm juice.

SYNCHRONIZATION OF EPILEPTIFORM ACTIVITY BETWEEN CA1 AND CA3 HIPPOCAMPAL FIELDS UNDER SYNAPTIC AND NON-SYNAPTIC CONDITIONS IN RAT BRAIN SLICES
Authors: Zapukhliak O.S. , Netsyk O.V. , Isaev D.S.
Published: July 2020

Relevance. Over-synchronization of neuronal activity results in epileptic-like discharges that can lead to seizures and status epilepticus. Understanding mechanisms of neural net synchronization could provide new insights into the treatment of epileptic disorders.

Objective: to compare the levels of synchronization between CA3 and CA1 hippocampal zones during epileptiform activity induced under synaptic and non-synaptic conditions.

Materials and Methods. Transverse brain slices were obtained from 12-14 days old rats. For induction of epileptiform activity common pro-epileptic agents were used: bicuculline and 4-aminopiridine. Nonsynaptic epileptiform activity was induced by perfusion brain slices with low-Ca2+ and Cd2+-containing artificial cerebrospinal fluid (aCSF). Simultaneous extracellular recordings of field potentials were obtained from the CA3 and CA1 pyramidal cell layer with extracellular glass microelectrodes (2–3 MΩ). Signals were then low-pass filtered (kHz), amplified using a 2-channel differential amplifier M1800, digitized at 10 kHz using analog-to-digital converter. The level of synchronization between CA3 and CA1 was evaluated using cross-correlation analysis. 

Results: Perfusion hippocampal slices with bicuculline and 4-aminopyridine induced epileptiform activity with high level of synchronization between CA3 and CA1 hippocampal zones. Removing Ca2+ from extracellular solution as well as adding CdCl2 to the perfusion aCSF induced epileptiform activity that was not synchronized between hippocampal CA3 and CA1 fields. 

Conclusions: Synaptic interaction account for high level of CA3-CA1 synchronization induced by pro-epileptic agents bicuculline and 4-aminopiridine. Under non-synaptic conditions, local cellular interactions induce epileptiform activity with no synchronization between CA3 and CA1 hippocampal zones.
­Limites legais a gratuidade da justiça ofertada na Justiça do Trabalho
Authors: Almeida Maira de Souza
Published: July 2020

A Reforma Trabalhista operacionalizada pelo Estado brasileiro no ano de 2017 alterou substancialmente diversos institutos jurídicos consagrados na seara trabalhista e, por essa razão, importa questionar sobre qual seria a interpretação juridicamente adequada a partir desse novo padrão normativo, a fim de que não se comprometa o direito fundamental de acesso à Justiça e a independência funcional dos juízes do trabalho. No que concerne ao direito de acesso à Justiça por parte dos trabalhadores, importa verificar as mudanças no instituto de gratuidade da Justiça e sua compatibilidade com a Carta Constitucional brasileira. A presente pesquisa sugere uma nova abordagem hermenêutica da nova legislação, tendente a afastar as interpretações inconstitucionais e/ou contrárias aos Direitos Humanos e aos princípios específicos da seara trabalhista.
