Traditionally, the automatic recognition of human emotions has heavily relied on sensors placed on the body to collect physiological data. However, recent advancements have revealed an alternative approach that utilizes video footage of human faces to estimate heart rate by analyzing changes in RGB color during the cardiac cycle. This contactless method, known as photoplethysmography (PPG) signal extraction, eliminates the need for physical contact. This study introduces a groundbreaking technique for classifying human emotions by leveraging contactless PPG signals. Various methods for extracting PPG signals were examined using a widely used emotional database.

Facilitating real-life creative insight through psychedelic virtual reality
Authors: Siimon Timo , Tulver Kadi , Kaup Karl Kristjan , Vasser Madis , Aru Jaan
Published: May 2023

The goal of the present work was to study the potential of facilitating creative insight in a real-life setting. To that end, participants were recruited who were struggling with a creative problem and had reached an impasse. Based on previous research, we hypothesized that solutions might be facilitated through virtual reality that replicates visual content experienced under the influence of psychedelics. Psychedelic visual experiences might support creative insight by relaxing the priors and constraints the person has about their creative problem. To test this idea, we tested a psychedelic virtual reality (VR) and developed a novel VR control environment. We observed that qualitatively psychedelic VR was more useful for eliciting creative insights than the control. We provide a thematic analysis demonstrating that psychedelic VR supported several aspects of creative insight. Taken together, we tested a novel method of psychedelic virtual reality to enhance creativity in real-life settings and observed encouraging results, which need to be investigated in larger studies.
Diversity, Identity, and Data
Authors: Topaz Chad M. , Brooks Heather Z. , Kan Unchitta , Sandstede Björn , Smith Christian Michael
Published: May 2023

While quantitative approaches cannot replace disciplinary insights from the social sciences and humanities, they can sometimes provide new perspectives. Building upon research from psychology and organizational theory that demonstrates how interacting groups may benefit both from diversity and from shared identity, we present a mathematical framework to explore the interplay of these collective attributes. We define intersecting diversity to capture the distribution of multidimensional identity traits and shared identity to describe the extent to which traits are shared amongst individuals. Although these two quantities are theoretically independent, we find a strong negative correlation between them in two sample data sets: principal creative contributors to Hollywood box office movies and American Community Survey data on state populations. This apparent trade-off between group diversity and shared identity poses a dilemma as both attributes are beneficial for group functioning.
The COVID-19 Pandemic and a Resurgence of Motherhood Wage Penalties in the United States
Authors: Glauber Rebecca , Yavorsky Jill , Qian Yue
Published: May 2023

BackgroundThe total motherhood wage gap among U.S. college-educated women closed over the past two decades and was eliminated by the early 2010s. It is not clear, however, whether the COVID-19 pandemic reversed these trends.MethodsDrawing on nationally representative data from the 2000–2022 Current Population Surveys, this study uses linear regression models to estimate trends in the total motherhood wage gap among college-educated and non-college-educated women who work full-time.ResultsIn the decade leading up to the COVID-19 pandemic, college-educated women with children did not pay a substantial motherhood wage penalty, but their wages began to decline at the onset of the pandemic, and the decline accelerated over the following years. By the end of 2022, college-educated women paid a 6% wage penalty for motherhood. In contrast to college-educated women, women without a college degree did not experience a substantial change in the motherhood wage penalty during the pandemic.ContributionOur study provides new evidence indicating that by 2022, three years into the pandemic, college-educated mothers experienced the highest motherhood wage penalty since the turn of the 20th century, reversing two decades of progress for this group of women. This study reveals the longer-term career-related ramifications of the pandemic for college-educated mothers and highlights the precarity of mothers’ economic progress related to external shocks, especially those that disrupt childcare and educational systems.
Online Surveys in Non-Democratic Contexts: Evidence from Russia
Authors: Korsunava Viyaleta , Sokolov Boris
Published: May 2023

How do online surveys perform in non-democratic contexts? To address this question, we compared the data from two web surveys (WSs), conducted in Russia in 2018 and 2020, using opt-in panels, to the offline data from round 7 of the World Values Survey (fieldwork in Russia 2017), round 9 of the European Social Survey (fieldwork in Russia 2018-2019), and the 2010 Russian Census data. We found that (a) various problematic response styles were somewhat more prevalent in WSs but the average time spent per item of the data from WSs is comparable to that in the offline sample; (b) WSs under-covered older, less educated and rural respondents, compared to both the offline sample and the Census benchmarks; (c) online respondents expressed considerably more liberal views on such issues as homosexuality, abortion, and divorce, as well as gender equality, compared to offline respondents (by 10% of the total scale range for each domain); and (d) WSs produced slightly different nomological networks of attitudinal orientations.
A case report of tubal high grade serous carcinoma, which was diagnosed incidentally after appendectomy
Authors: HÖBEK Pelin , ONAN M.anıl
Published: May 2023

Primary tubal carcinoma is a uncommon tumor of female ganitale system. The clinical approach of primary tubal cancers is similar to primary ovarian cancers. Fallopian tube carcinoma is hard to diagnosed preoperatively because of its uncertain symptoms. Providing optimal cytoreductive surgery is the most important treatment step in ovarian, tubal and peritoneal carcinomas.

We report a case of serous tubal intraepithelial carcinoma and appendix metastasis. A 65 years old post-menopausal woman (gravida 4, para 3) submitted to an external hospital with lower abdominal pain and acute abdominal symptoms. Appendectomy was performed on the patient with preliminary diagnosis of appenditis. The pathology result was reported as high grade serous carcinoma infiltration. Staging surgery was performed with the diagnosis of carcinoma. Until the final pathology result, the diagnosis was considered as appendiceal metastasis of serous tubal cancer. Our clinical and surgical approach to the case, which was diagnosed incidentally with an appendectomy specimen and reported as high grade tubal serous carcinoma, is presented as a case study.

Renforcer la gestion budgétaire pluriannuelle des communes et intercommunalités pour faire face aux enjeux du XXIe siècle
Authors: Poulin Anthony
Published: May 2023

Dans un monde en pleine mutation, les collectivités locales ont un rôle majeur à jouer pour amplifier la transition écologique et sociale. Pour cela, les communes et intercommunalités doivent consacrer des moyens budgétaires importants et ciblés dans un contexte tendu, marqué par la raréfaction des deniers publics. Pour façonner efficacement l’avenir, l’approche pluriannuelle s’impose. La construction de PPI « pro-climat » sécurise les moyens publics alloués à la transition écologique. Elle permet de changer en profondeur la construction de l’ensemble des politiques publiques et d’entraîner les habitants et le secteur économique dans cette voie. Le succès des plans pluriannuels dépend de la capacité à garantir des ressources durables aux collectivités et d’asseoir un partenariat pluriannuel de confiance entre l’État et les collectivités. Cela pourrait par exemple prendre la forme d’une loi de programmation spécifique pour le climat qui comprendrait un volet territorial, mais, pour aller plus loin, il est aussi nécessaire de repenser les critères de bonne gestion des budgets locaux.

Phosphorus Removal from Water and Waste Water by Chemical Precipitation Using Alum and Calcium Chloride
Authors: A. M. Mohammed Sawsan , Abbas Shanshool Haider
Published: May 2023

Phosphorus is usually the limiting nutrient for eutrophication in inland receiving waters; therefore, phosphorus concentrations must be controlled. In the present study, a series of jar test was conducted to evaluate the optimum pH, dosage and performance parameters for coagulants alum and calcium chloride. Phosphorus removal by alum was found to be highly pH dependent with an optimum pH of 5.7-6. At this pH an alum dosage of 80 mg/l removed 83 % of the total phosphorus. Better removal was achieved when the solution was buffered at pH = 6. Phosphorus removal was not affected by varying the slow mixing period; this is due to the fact that the reaction is relatively fast.The dosage of calcium chloride and pH of solution play an important role in phosphorus removal. The removal efficiency increases with increasing pH, and the optimum dosage of CaCl2 was 60 mg/l. Alum demonstrated much better results in phosphorus removal than CaCl2.

Multi step risk assessment process is used in this study in the assessment of risks caused bycontamination of indoor air by lead particles emitted from domestic electrical generators. Two portable electricalgenerators are tested under controlled indoor conditions (Radial LG (0.9 keV) fueled with benzene and oil and TigMax(3 keV), fueled with benzene only). Lead particles in air were sampled by using portable dust sampler (Sniffer, L-30).The atmospheric particulate sampling process is carried out in a flat located in the first floor of a three stories buildinglocated in Baghdad city, Al-Zafarania region. The lead concentration in the digested filter papers is measured by usingatomic absorption spectrophotometer (Buck, USA). Dose-to-risk conversion factor is applied in this study to estimate thepotential cancer risk to Baghdad’s population related to continuous inhalation of airborne lead at the mean observedconcentrations. The results of toxicity analysis indicate that public exposure to airborne lead at the mean observedconcentration of 4.991  g/m3 can increase the risk of cancer at a rate of 12 extra cancer cases in a group of millionexposed individuals. Males are found to be at greater risk than females because of higher inhalation rates. Children arefound to be the most sensitive group due to low body weight (about 101 expected additional cancer cases in a group ofmillion exposed child).

its primary task, administering an electoral contest. Building the EMB workforce’s capacities reinforces and inculcates electoral administration values and principles, those of integrity, impartiality, transparency, efficiency, sustainability and service-mindedness. By contrast, poor or inadequate training hampers service delivery and increases the risk of errors that negatively impact the reputation of the EMB or the election outcome itself. This Policy Paper addresses two different but interlinked issues: how to build and strengthen the capacities of EMB staff and workforce (both technical and lifelong learning); and how to build institutional capacities for delivering both types effectively. The paper is supplemented with findings from: a survey conducted in 2021; a 2021 case study series on the institutionalization of electoral training and education; and a 2020 workshop. This paper provides recommendations for practitioners seeking to strengthen their training and professional development programmes, as well as highlighting recommendations for the electoral assistance community.

It is inappropriate for people to be trapped in products containing elements of usury which result in imperfection of the pilgrimage because they depart in a way that contains elements of gharar. The practice opens the door to danger, and brings harm. The Ministry of Religion which has the authority to evaluate the existence of hajj bailout funds with the Regulation of the Minister of Religion (PMA) RI No. 24 of 2016. The Hajj bailout fund is intended to meet the customer's lack of funds in meeting the minimum requirements to get the Hajj portion. This program is enough to ease the people in preparing for the departure of the pilgrimage. For LKS, this program is also a benefit where LKS gets Ujrah from every customer who participates in the Hajj bailout program. On the other hand, the bailout program creates and contains disadvantages that are not in accordance with Islamic ethics. Hajj bailouts incur debts that can cause damage to the purity of the pilgrimage. The Hajj bailout financing contract at LKS attracts ujrah based on the time and amount of the bailout fund. This practice is not in accordance with the DSN-MUI Fatwa No. 29 of 2002. The hajj bailout has an effect on the length and length of the waiting list for hajj departures.
