A New Scenario Framework for Equitable and Climate-Compatible Futures
Authors: Ranjan Ankita , Kanitkar Tejal , Jayaraman T
Published: September 2023

This paper proposes and demonstrates a new modelling approach and scenario framework for global burden-sharing, which foregrounds questions of climate and energy justice. We classify 134 countries into four development categories - high development, medium development, low development, and least development based on thirteen development and energy indicators. Using the quadratic plateau model, we estimate that an energy threshold of 94 GJ (±15) and an income threshold of $28,679 (±4179) is necessary for meeting sustained levels of development defined by indicators for health, education, and infrastructure. We construct baseline scenarios for convergence to, or divergence from, these and other threshold values drawn from the literature, for each development category. Emissions constraints are then imposed in the form of the remaining carbon budget corresponding to the temperature targets of the Paris Agreement to assess the degree of energy-emissions and energy-GDP decoupling that would be required to meet these targets without reliance on carbon-dioxide removal. Our results show that limiting warming to well below 2 deg. C and o 1.5 deg. C requires significantly higher effort across all regions, with the global effort differing only marginally across scenarios, irrespective of whether energy and climate equity are considered or not. However, the distribution of the global effort across development categories varies significantly, depending on whether energy and climate equity are considered or not. The mitigation burden for the highest development category is almost six times higher if climate equity is considered compared to scenarios in which climate equity is compromised. In contrast, the effort required by the least developed category is doubled if climate equity is not considered.

Published: September 2023

The social isolation resulting from governments’ responses to the COVID-19 pandemic likely limited support available to mothers. Evidence suggests tasks like childcare and domestic work fell disproportionately on mothers during the pandemic, with consequences for their wellbeing. We explore how the pandemic affected emotional and practical support available to mothers between March and August 2020 and whether changes in support are associated with changes in their paid work and mental health. Data were collected in August 2020 from 1528 UK and US mothers with at least one child under 5-years using a cross-sectional survey and are analysed using regression models. Women’s in-person contact with support networks decreased, while virtual interactions increased. Most mothers experienced a ‘nuclearization’ of in-person support: childcare from fathers and siblings increased or remained constant but decreased from the grandparental generation. Women receiving less support during the pandemic had higher odds of reducing participation in paid work. Associations between support and mental health are limited. We also identify women who concurrently experienced reduced support and increased need for help, representing a particularly vulnerable group. The nuclearization of maternal social networks likely increased physical and emotional pressures on the immediate family, risking parental burnout and affecting reductions in female participation in paid labour. There is a need for reliable and affordable childcare options that help reduce women’s burden of unpaid care labour, allowing them to re-enter (or remain in) paid labour.
Title: Effective Perishable Products Management: Strategies, Challenges, and Sustainable Practices
Authors: Egon Kaledio , ROSINSKI JULIA
Published: September 2023

Perishable products are products that expire or lose value over time, such as food, flowers, pharmaceuticals, event tickets, and hotel rooms. Managing perishable inventory is a challenge for businesses that deal with these products, as they have to balance supply and demand, avoid waste and spoilage, and maximize revenue and customer satisfaction. It provides insights into inventory management, quality control, supply chain considerations, and the growing importance of sustainability in the context of perishable goods.

TRANSLATING A LADDER FROM AI/ML, NOVEL BIOMARKERS AND EV’S FOR PERSONALIZED MEDICINE IN NEURODEGENERATIVE DISEASE AND THERAPEUTICS
Authors: HARSHA JHA
Published: September 2023

Diseases which are characterized by the progressive loss of neurons' structure or function, leading to deterioration in cognitive and motor function. A disease's presence or severity can be determined objectively by biomarkers, which are then used to monitor, diagnose, and track the development of a disease. There are several different categories of biomarkers that have been identified for neurodegenerative diseases, including genetic, epigenetic, protein, imaging, and behavioral biomarkers. These biomarkers can be utilised separately or in combination to assist the development of targeted therapeutics by providing a better knowledge of the underlying illness process. In this review, we discuss the various categories of biomarkers that have been identified for neurodegenerative diseases and their potential uses in the clinical setting. It is significantly being used in the area of neurodegenerative diseases and therapeutics. A kind of extracellular vesicles implicated in brain damage in a variety of ways; they spread inflammation throughout the brain. A barrier called the blood-brain barrier (BBB) mediates neuronal signal mediation, propagation, and neuroprotection.. This paper focuses on the evidence which is mounting that the functions of EV are linked to the neurological pathogenic illnesses of machinery aiding in the growth and spread of the diseaseIn this paper, we discuss the current state of AI applications in this area. We begin by providing an overview of neurodegenerative diseases and the challenges they present. We then describe the various ways in which AI is being used in the field, including drug discovery and development, diagnosis and prognosis, patient care, clinical trials, and basic research. Finally, we outline some of the key directions for future research in this area. We have also designed a sample program with the help of HTML, CSS and JAVA to design personalised medicine. . Overall, our analysis indicates that AI has the potential xi affect on NDD’s and therapeutics, and could be a step towards the development of new and improved treatments for these conditions.
Is something rotten in the state of Denmark? Cross-national evidence for widespread involvement but not systematic use of questionable research practices across all fields of research.

Published: September 2023

Questionable research practices (QRP) are believed to be widespread, but empirical assessments are generally restricted to a few types of practices. Furthermore, conceptual confusion is rife with use and prevalence of QRPs often being confused as the same quantity. We present the hitherto most comprehensive study examining QRPs across scholarly fields and knowledge production modes. We survey perception, use, prevalence and predictors of QRPs among 3,402 researchers in Denmark and 1,307 in the UK, USA, Croatia and Austria.Results reveal remarkably similar response patterns among Danish and international respondents (τ = 0.85). Self-reported use indicates whether respondents have used a QRP in recent publications. 9 out of 10 respondents admitted using at least one QRP. Median use is three out of nine QRP items. Self-reported prevalence reflects the frequency of use. On average, prevalence rates were roughly three times lower compared to self-reported use. Findings indicated that the perceived social acceptability of QRPs influenced self-report patterns. Results suggest that most researchers use different types of QRPs within a restricted time period. The prevalence estimates, however, do not suggest outright systematic use of specific QRPs. Perceived pressure was the strongest systemic predictor for prevalence. Conversely, more local attention to research cultures and academic age was negatively related to prevalence. Finally, the personality traits conscientiousness and, to a lesser degree, agreeableness were also inversely associated with self-reported prevalence. Findings suggest that explanations for engagement with QRPs are not only attributable to systemic factors, as hitherto suggested, but a complicated mixture of experience, systemic and individual factors, and motivated reasoning.
Impact of genetic predisposition to late-onset neurodegenerative diseases on early life outcomes and brain structure

Published: September 2023

Most patients with late-onset neurodegenerative diseases such as Alzheimer's and Parkinson's have a complex aetiology resulting from numerous genetic risk variants of small effects located across the genome, environmental factors, and the interaction between genes and environment. Over the last decade, genome-wide association studies (GWAS) and post-GWAS analyses have shed light on the polygenic architecture of these diseases, enabling the use of polygenic risk scores (PRS) for estimating an individual's relative genetic liability for presenting with the disease. PRS can screen and stratify individuals based on their genetic risk, potentially years or even decades before the onset of clinical symptoms. An emerging body of evidence from various research studies suggests that genetic susceptibility to late-onset neurodegenerative diseases might impact early life outcomes, including cognitive function, brain structure and function, and behaviour. This article summarises recent findings exploring the potential impact of genetic susceptibility to neurodegenerative diseases on early life outcomes. A better understanding of the impact of genetic susceptibility to neurodegenerative diseases early in life could be valuable in disease screening, detection, and prevention and inform treatment strategies before significant neural damage has occurred. However, ongoing studies have limitations. Overall, our review found several studies focused on APOE haplotypes and Alzheimer's risk, but a limited number of studies leveraging polygenic risk scores or focused on genetic susceptibility to other late-onset conditions.
AI-generated visuals of car-free US cities help improve support for sustainable policies

Published: September 2023

Americans are often reluctant to support policies that aim to meaningfully change transportation. Here we show how new techniques from artificial intelligence can be harnessed to increase public support for green policies. We use text-to-image generative AI models to create re-imagined, car-free versions of various streets in America and find that across two large-scale survey studies (N = 3,129), viewing these re-imaginations significantly increases support for a hypothetical sustainable transport bill.
Direct perception of affective valence from vision
Authors: Sadeghi Saeedeh , Gu Zijin , Kuceyeski Amy , De Rosa Eve , Anderson Adam K.
Published: September 2023

Affect has been posited as the basic subjective feeling component underlying all experience, arising directly from internal states of the body and the closely related proximal senses. By contrast, in the distal senses such as vision, affect is thought to be indirect, largely mediated by higher level processes. Evidence from machine learning suggests affective features may be embedded in the ecological statistics of the external environment but their causal role, if any, remains unclear. Here we provide evidence from machine and human observers that affective valence can be decoded directly from visual features. A visual valence (VV) model of low-level image statistics trained to predict Normative Valence (NV) in 8000 emotionally charged images transferred even more robustly to predicting valence of abstract paintings without conceptual content. Manipulating VV and availability of conceptual analysis, enhanced the contribution of VV to valence experience. In the brain, in contrast with NV, VV resided exclusively in early and mid-level visual areas. Employing a deep generative network, brain activity in these regions synthesized new images containing predicted positive versus negative VV. There are distinct competing modes determining valence experience, one indirectly from meaning, and the other derived from ecological visual statistics, affording direct perception of valence as an apparent objective property of the external world.
Choice with Ethical Outcomes: Sign Effect, Commodity Effect, & Ethical Theory Preference
Authors: Cox David J. , Javed Asim
Published: September 2023

Researchers have found significant utility in approaching choice from a behavioral economics lens. Recently, this framework has begun to be extended to the description and prediction of clinical-ethical choice. Here, researchers have found that common behavioral economics effects occur with clinical-ethical choice at the group level (e.g., framing effects, effort discounting, delay and probability discounting) and at the individual level (probability discounting). The current study sought to examine: the sign effect in ethical probability discounting, the commodity effect between monetary and ethical outcomes, and correlations among rates of monetary and ethical discounting, probability matching with money, and ethical theory preference. We observed: a sign effect with ethical outcomes consistent with past probability discounting research; a commodity effect with monetary outcomes discounted more steeply than ethical outcomes; no significant correlations among discounting tasks; and one of 12 statistically significant correlations between ethical theory preference and ethical discounting. In total, the present work further demonstrates the presence of behavioral economics effects with ethical decision-making. However, choice with ethical outcomes may not easily be predicted by choice with other commodities, measures in behavioral economics, or ethical theory preference.
Using the Mobile Toolbox in Child and Adolescent Samples: Initial Evidence of Reliability, Validity, and Acceptability
Authors: Young Stephanie , Novack Miriam , Dworak Elizabeth , Kaat Aaron J , Gershon Richard
Published: September 2023

The Mobile Toolbox (MTB) is a novel remote assessment system originally designed for adults. This paper presents preliminary evidence of the MTB cognitive measures’ psychometric properties in a sample of 99 children (M age = 11.79 years; 36% female; 53% White, 33% Black/African American, 9% Asian; 15% Hispanic). Strong performance on practice items and completion rates provides evidence of feasibility in this sample. Reliability was good across five of the six measures, and marginal on one. The MTB measures demonstrated moderate to large correlations with age and with measures of similar constructs on the NIH Toolbox. Results suggest that the MTB has potential for use in pediatric samples and further validation studies are encouraged.
Recruitment and retention of adolescents for an ecological momentary assessment measurement burst mental study: the MHIM engagement strategy
Authors: Murray Aja Louise , Xie Tong , Power Luke , Condon Lucy
Published: September 2023

Introduction: Recruitment and long-term retention of adolescent participants in longitudinal research is challenging, and may be especially so in studies involving remote measurement and biosampling components. Recruitment and retention can benefit from the use of specific evidence-based engagement strategies that are built in from the earliest stages. Methods and analysis: The current protocol describes the planned participant engagement strategy for the Mental Health in the Moment Study: a multi-modal measurement burst study of adolescent mental health across ages 11-19. Informed by a review of the evidence on effective engagement strategies as well as consultations with adolescents via two young person advisory groups (YPAGs), the protocol incorporates strategies in four key areas: consultations/co-design with the target population, incentives, relationship-building, and burden/barrier reduction. We also discuss limitations, and future directions in engaging adolescents in longitudinal research. Ethics and dissemination: Ethics approval is not required for the present study, which is based on a literature review and co-production approach. The study protocol for MHIM will be separate and MHIM will undergo ethical review prior to data collection. Findings will be disseminated through professional networks, presentations at conferences and manuscripts published in scientific journals.
Does Talker Variability Help Adults Learn Novel Words?
Authors: Abu El Adas Sandy , Yen Ivy , Levi Susannah V.
Published: September 2023

Exposure to multiple talkers has been shown to be beneficial for adults learning speech sounds in a second language and for children learning novel words in a lab-based word learning task. The current study examines the extent to which variability is beneficial for adults in a word learning task and how individual differences in reading and language skills affect performance. Seventy-six participants were randomly assigned to either the multiple-talker (four talkers) or single-talker condition and learned novel object-nonword pairings. To assess word learning, listeners completed three naming tasks throughout the study (after 4 exposures, after 8 exposures, and after a brief delay) in which they had to generate the name of the object. Overall, listeners with higher language skills showed better word learning than those with poorer language skills. No effects of reading ability or talker variability were found. These results suggest that variability may only be beneficial in some tasks.
Comparing the Performance of Google Translate and SYSTRAN on Arabic Lexical Ambiguity
Authors: Aldawsari Hamad Abdullah H
Published: September 2023

Machine translation systems face many challenges when dealing with Arabic lexical ambiguity, which affects the quality and accuracy of their translations. This study investigates how two popular MT systems, Google Translate and SYSTRAN, handle three problematic linguistic features of the Arabic language: homonyms, heteronyms, and polysemes. A test suite was designed to include sentences that contain these features in different contexts and domains. The translations produced by the two MT systems were evaluated by four independent evaluators for intelligibility and accuracy using a four-point scale. Results showed that both MT systems struggled with the three chosen linguistic features, with average scores below 40%. Google Translate outperformed SYSTRAN in almost every sentence in the test suite. Both systems scored better in intelligibility than in accuracy. Heteronyms proved to be the most challenging for both MT systems due to the unique design of Arabic discretization, which is not yet recognized by translation systems. This study contributes to the field of machine translation by providing a comprehensive analysis of Arabic lexical ambiguity and its impact on MT quality, as well as suggesting possible ways to improve MT systems for Arabic-English translation.
Secrets and Ties: The Invisible Power of Hidden Relationships in Underground Social Movements
Authors: Sheng Jeff T.
Published: September 2023

Abstract: This article develops a framework and set of theories for understanding the formation, maintenance, and emergence of underground social movements—namely, those in which participants must remain hidden during a part of movement activity due to stigma, sanction, or laws, but depending on circumstances may exist partially hidden or fully “above ground” at various stages. It extends previous research on hidden and clandestine movements beyond a focus on those defined by extremist political ideologies, violence, revolutions, and wartime resistance, to include others based on stigmatized social identities and beliefs. Specifically, I draw on a ten-year qualitative case study from 2009 to 2019, consisting of sixty in-depth interviews and ethnographic observations of over 150 LGBT U.S. military service members who were secretly involved in some form of hidden mobilization in the repeal of various policies meant to exclude LGBT persons from openly serving in the military. I identify four different phases of movement formation—individual grievances, dyad creation, hidden networks, and movement emergence—and introduce the concept of “hidden distinctiveness” to capture how secrecy can become a strength for such movements.
Exploring the impact of mobility and selection on stone tool recycling behaviors through agent-based simulation
Authors: Coco Emily
Published: September 2023

Recycling behaviors are becoming increasingly recognized as important parts of the production and use of stone tools in the Paleolithic. Yet, there are still no well-defined expectations for how recycling affects the appearance of the archaeological record across landscapes. Using an agent-based model of recycling in surface contexts, this study looks how the archaeological record changes under different conditions of recycling frequency, occupational intensity, mobility, and artifact selection. The simulations also show that while an increased number of recycled artifacts across a landscape does indicate the occurrence of more scavenging and recycling behaviors generally, the location of large numbers of recycled artifacts is not necessarily where the scavenging itself happened. This is particularly true when mobility patterns mean each foraging group spend more time moving around the landscape. The results of the simulations also demonstrate that recycled artifacts are typically those that have been exposed longer in surface contexts, confirming hypothesized relationships between recycling and exposure. In addition to these findings, the recycling simulation shows how archaeological record formation due to recycling behaviors is affected by mobility strategies and selection preferences. While only a simplified model of recycling behaviors, the results of this simulations give us insight into how to better interpret recycling behaviors from the archaeological record, specifically demonstrating the importance of contextualizing the occurrence of recycled artifacts on a wider landscape-level scale.
Research collaboration and knowledge development in Africa: the case of neonatal conditions
Authors: de Sousa Vieira Elizabeth
Published: September 2023

The literature has discussed the positive/negative effects of research collaboration (RC). However, there is no study that looks at the effect of RC especially international research collaboration (IRC) on key developments in a research area.Using Main Path Analysis (MPA), I examined the literature on neonatal conditions (NC) produced by African scientists between 2000 and 2019. I found the (1) estimates of deaths of children under five years and their causes, with a focus on neonates and stillbirths, (2) usefulness of tools to collect data on NC-related variables, (3) identification of interventions to reduce deaths, and (4) treatment of hyperbilirubinemia in African neonates as the most important developments in NC in Africa.The high presence of articles with RC, in the MPA, especially those involving IRC between one or more scientists from a single African country and scientists from several non-African countries (60% of the studies) highlights the positive effect of RC on key developments of an area. About 40% of the articles make a reference to the Saving Newborns Lives programme, the Child Health Epidemiology Reference Group (CHERG) or the departments of the World Health Organization (WHO).
Testing the Purchasing Power Parity Hypothesis with Tourism Price Indices for OECD Countries
Authors: Bekő ​​Jani , Boršič Darja
Published: September 2023

This chapter investigates the empirical validity of PPP for the group of 26 OECD economies. Four improvements are derived from the re- search. First, the testing strategy relies on two price indicators: the consumer price index for all items and the consumer price index for hotels and restaurants including catering and accommodation services. Second, the PPP theory is scrutinized by employing two base currencies; the US dollar and the euro. Third, the mean reversion hypothesis of OECD countries’ real exchange rates is evaluated by a variety of first-generation panel unit root tests plus by the Pesaran CIPS unit root test integrating potential correlations across residuals of panel units. Fourth, the PPP model is inspected on a new data set covering the period from February 2002 to October 2022. The results re- veal robust evidence of mean reversion of real exchange rates in the panel of OECD countries.
Iodine-containing preparations in grain growing technologies

Published: September 2023

The urgency of researching and solving the problem of open and masked iodine deficiency, which manifests itself through several diseases, is now global. Many studies and programmes have been initiated on alternative methods of introducing iodine into human nutrition, and one of them is biofortification of crops. Biofortification of crops through fertilisers and foliar iodine fertilisation provides the best bioavailability of water-soluble forms of iodine for plants. At the same time, the functional role of iodine as a plant nutrient is understudied. The purpose of this study was to establish and substantiate the effectiveness of iodine-containing preparations in grain crops cultivation technologies. To fulfil this purpose, field and laboratory studies were carried out. The field multifactorial experiment was conducted on podzolic chernozems in a stationary experiment of the Department of Plant Science of the National University of Life and Environmental Sciences of Ukraine. Mathematical processing of the results was carried out using SAS 9.4 and Agrostat 6 software. The anti-stress effect of preparations with biologically active iodine under combined pre-sowing seed treatment and plant treatment during the growing season was identified – significant yield increments were obtained, even under conditions of severe air and soil drought during the growing season of grain crops. The application of background doses of fertiliser and the use of biologically active iodine products ensured a significant increase in yields. The average yield of winter wheat ranged from 2.96 to 6.46 t/ha; oats – from 2.79 to 5.41 t/ha, depending on the background of nutrition, disinfectant and preparations with biologically active iodine. Iodine-containing preparations are effective in the system of preventive protection during the treatment of seeds and plants during the growing season, which can substantially reduce the damage to wheat and oat plants by diseases. Treatment of crops during the growing season with iodine-containing preparations, especially in the late microstages, reduces the level of secondary disease infection and prevents infection of seeds that form on the mother plant and are subsequently the main source of pathogenic infection that develops after sowing seeds into the soil. The developed regulations will promote the use of iodine-containing preparations in crop cultivation technologies, which are particularly effective in regions with iodine deficiency in the environment

Waterflood-induced fracture or "Two-Step-Rate-Test" to improve reservoir injectivity
Authors: Alekberov R. R. , Volf A. A.
Published: September 2023

Low permeability reservoirs (less than 1 mD) are developed by intensive waterflooding. The agent is injected at pressures higher than the fracturing pressure, so that in almost every well involved in this procedure, there is spontaneous growth (injection) of artificial fractures in different directions with different characteristics, and so on. The relevance of the topic is due to a new procedure called two-stage reservoir injectivity enhancement using multiple injection modes, this technique is used to determine the test fluid injection pressure at which fracture growth will occur. The problem of this study is to increase the injectivity of the injection well in order to increase fluid production. The aim and purpose of the work is the process of increasing the injectivity of injection wells by "steps" (Step-Rate-Test is SRT): a study of the Tevlinsko-Russkinskoye field. The moment of autofracturing is determined by SRT and not by injectivity. The method of interpretation is plotting. The difference between SRT and 2-SRT is considered, the 2-SRT well treatment is carried out, the efficiency of the applied method and the results of the work are presented.
A review of some methods and results of studies in the "well - reservoir" system
Authors: Akhmetzyanov R. R.
Published: September 2023

The physicochemical interactions between drilling mud, rock and in-situ fluids in the "well - reservoir" system are of increasing interest to oilfield drilling researchers. Usually, the main aim of research is development of an optimal drilling fluid that provides trouble-free drilling, reducing non-productive time to eliminate various problems, and effectively exposes of oil and gas reservoirs under certain geological conditions. The history of research in this area goes back more than a dozen years. However, given the difficulties of modeling real geological conditions in the laboratory, and the characteristic attachment of previous results to them, there is still plenty of untapped potential. The purpose of this article is a literature review of the applied research methods to assess the level of scientific and technical development, evaluate the achieved research results, a possibility of their distribution to the target objects and further development.
An estimation of gas volume in the water-saturated part of Cenomanian gas reservoirs: a case study of the Medvezhye oil and gas condensate field
Authors: Fominykh O. V. , Leontiev S. A. , Khalin A. N.
Published: September 2023

The amount of remaining recoverable natural gas reserves is affected by the pinching of gas reserves by infiltrating water and degassing of formation water in the Cenomanian water-pressure complex. It is necessary to reliably determine the volume of gas-saturated water in order to estimate the volume of gas dissolved in produced water. The area of the gas-oil contact is determined by known methods, but the height of the reservoir zone, represented by gas-saturated water (transition zone), must be specified.

The fluid distribution and the structure of the transition zone depend on gravitational and capillary forces. These forces depend on the physical and chemical properties of the gas and formation water, as well as the composition and filtration properties of the reservoir. To calculate the thickness of the reservoir in which the process of gas dissolution in water takes place, it is proposed to consider it from the point of view of molecular diffusion processes.

The authors of the article propose an adapted VNIIGAZ method for determining the transition zone and the volume of water in which gas from underground gas storages is dissolved (a case study of the Medvezhye oil and gas condensate field). The proposed method for calculating the volume of gas dissolved in formation waters of Cenomanian gas deposits, taking into account diffusion, showed an acceptable result. The proposed method for calculating the volume of gas dissolved in formation waters of Cenomanian gas deposits, taking into account diffusion, gave an acceptable result.

Student evaluation of teaching (SET) has more than forty years of history as a tool of feedback in North American, Australian and European universities. In Russian universities it is not widespread, although increasing its implementation could solve the problem of Russian students feeling that they are not involved in the management of the educational process and improve the quality of courses and teaching. The barriers to the implementation of SET in the Russian higher education system, among other things, are concerns and prejudices of teachers and students, who see SET more as a problem than an effective tool. In this article, authors analyze the most common faculty concerns about student evaluations of teaching, obtained from ten focus groups in five Russian universities. Authors put collected opinions in the context of the recent methodological discussions about the validity of Student Evaluations of Teaching. The main idea is that SET is an effective tool of getting feedback in higher education and involvement of students and teachers in a dialogue and cooperation in the educational process, but highly questionable as a data source for administrative decisions.
