The psychological arrow of time drives temporal asymmetries in inferring unobserved past and future events
Authors: Xu Xinming , Zhu Ziyan , Zheng Xueyao , Manning Jeremy R.
Published: May 2022

How much can we infer about the past and future, given our knowledge of the present? Unlike temporally symmetric inferences about simple sequences, inferences about our own lives are asymmetric: we are better able to infer the past than the future, since we remember our past but not our future (i.e., the psychological arrow of time). What happens when both the past and future are unobserved, as when we make inferences about other people’s lives? We had participants in two experiments view segments of two character-driven television dramas. They wrote out what would happen just before or after each just-watched segment. Participants were better at inferring past (versus future) events. This asymmetry was driven by participants’ reliance on characters’ conversational references in the narrative, which tended to favor the past. We also carried out a meta analysis to estimate the prevalence of temporal asymmetries in past versus future conversational references in hundreds of millions of dialogues from television shows, popular movies, novels, and written and spoken natural conversations. We found that, on average, references to the past are 1.45 times more prevalent in human conversations than references to the future. Our work reveals a temporal asymmetry in how observations of other people’s behaviors can inform us about the past and future.

In times of crisis, real-time data mapping population displacements are invaluable for targeted humanitarian response. The Russian invasion of Ukraine on February 24, 2022 forcibly displaced millions of people from their homes including nearly 6m refugees flowing across the border in just a few weeks, but information was scarce regarding displaced and vulnerable populations who remained inside Ukraine. We leveraged near real-time social media marketing data to estimate sub-national population sizes every day disaggregated by age and sex. Our metric of internal displacement estimated that 5.3m people had been internally displaced away from their baseline administrative region by March 14. Results revealed four distinct displacement patterns: large scale evacuations, refugee staging areas, internal areas of refuge, and irregular dynamics. While this innovative approach provided one of the only quantitative estimates of internal displacement in virtual real-time, we conclude by acknowledging risks and challenges for the future.
Suomalaisten lapsiperheiden ylivelkaantuneisuus maksuhäiriömerkintöjen valossa

Published: May 2022

Tämä artikkeli kuvaa lapsiperheiden ylivelkaantuneisuutta Suomessa. Vanhempien velkaongelmilla on sekä välittömiä että ylisukupolvisia vaikutuksia lapsiin ja nuoriin. Käytämme maksuhäiriömerkintöjä ylivelkaantuneisuuden mittarina. Tutkimme maksuhäiriömerkintöjen kohdentumista lapsiperheväestössä hyödyntämällä Tilastokeskuksen FOLK-aineistoa, johon on yhdistetty tiedot luottotietorekisteristä. Suomessa on yli 113 000 alle 18-vuotiasta lasta perheissä, joissa perheen vanhemmalla on vähintään yksi maksuhäiriömerkintä. Vanhempien maksuhäiriömerkintä yhdistyy työttömyyteen, pieniin tuloihin ja matalaan koulututukseen. Maksuhäiriömerkinnät ovat yleisiä yhden vanhemman perheissä, joissa yli viidenneksellä on maksuhäiriömerkintä. Näissä perheissä elää noin 47 000 lasta. Luvut ovat merkittäviä sillä vanhemman maksuhäiriömerkintä voi estää lasta saamasta terveysvakuutusta, laskutuspohjaista sopimusta tai vuokra-asuntoa. Lapsiperheiden velkaongelmia ehkäiseville interventioille on tarvetta.
Explaining population booms and busts in Mid-Holocene Europe
Authors: Kondor Daniel , Bennett James S , Gronenborn Detlef , Antunes Nicolas , Hoyer Daniel , Turchin Peter
Published: May 2022

Archaeological evidence suggests that the population dynamics of Mid-Holocene (Late Mesolithic to Initial Bronze Age, ca. 7000-3000 BCE) Europe are characterized by recurrent booms and busts of regional settlement and occupation density. These boom-bust patterns are documented in the temporal distribution of 14C dates and in archaeological settlement data from regional studies. We test two competing hypotheses attempting to explain these dynamics: climate forcing and social dynamics leading to inter-group conflict. Using the framework of spatially-explicit agent-based models, we translated these hypotheses into a suite of explicit computational models, derived quantitative predictions for population fluctuations, and compared these predictions to data. We demonstrate that climate variation during the European Mid-Holocene is unable to explain the quantitative features (average periodicities and amplitudes) of observed boom-bust dynamics. In contrast, scenarios with social dynamics encompassing density-dependent conflict produce population patterns with time scales and amplitudes similar to those observed in the data. These results suggest that social processes, including violent conflict, played a crucial role in the shaping of population dynamics of European Mid-Holocene societies.
The Role of Adults in Protecting Children (A Theory of Change for the Primary Prevention of Child Sexual Abuse)
Authors: Nguyen Amy Thao , Bouchie Gwendolyn S. , Brewer Katelyn N. , Sherard Donna , Longfield Kim
Published: May 2022

Child sexual abuse (CSA) is a pervasive public health issue impacting physical, mental, and behavioral health outcomes across the lifespan; however, many programs focus heavily on response rather than prevention strategies. They also lack grounding in a common theoretical model for CSA prevention. This manuscript introduces a Theory of Change (ToC) for Adult Prevention of CSA that utilizes a Social Behavior Change approach. This theory identifies individual and contextual factors that address the complexity of CSA prevention, depicted in a social-ecological model. The ToC was developed using a scoping literature review, semi-structured interviews with stakeholders (N=27), and a community engagement survey (N=183). The ToC maps a series of causal pathways for prevention among four adult groups and is an important tool for stakeholders working in child protection since it supports program design, advocacy initiatives, and training programs. It is expected that the ToC will contribute to broader discourse on best practices for CSA prevention.
Understanding the Trajectories of Population Decline Across Rural and Urban Europe: A Sequence Analysis
Authors: Newsham Niall , Rowe Francisco
Published: May 2022

Population decline is projected to become widespread in Europe, with the continental population set to reverse its longstanding trajectory of growth within the next five years. This represents unfamiliar demographic territory. Despite this, literature on decline remains sparse and our understanding porous. Particular epistemological deficiencies stem from a lack of both cross-national and temporal analyses of population decline. This study seeks to address these gaps through the novel application of sequence and cluster analysis techniques to examine variations in population decline trajectories since 2000 in 696 sub-national areas across 33 European territories. The methodology allows for a holistic understanding of decline trajectories capturing differences in the ordering, timing, magnitude and spatial structure of population decline. We identify a typology of population decline distinguishing seven distinct pathways to depopulation and chart their geographies. Results revealed differentiated pathways of depopulation in continental sub-regions, with consistent and rapid declines in the east, persistent but moderate declines in central Europe, accelerating declines in the south and decelerating population declines in the west. Results also revealed differentiated patterns of depopulation across the rural-urban continuum, with urban and populous areas experiencing deceleration in population decline, while population decline accelerates or stabilises in rural areas. Small and mid-sized areas displayed heterogeneous depopulation trajectories, highlighting the importance of local contextual factors in influencing trajectories of population decline.
Dismissed and newly planned babies during the COVID-19 pandemic. A study of the motivations behind changes in fertility plans and behaviors in Italy
Authors: LUPPI FRANCESCA , Arpino Bruno , Rosina Alessandro
Published: May 2022

While early evidence of the impact of the COVID-19 crisis on births has suggested a depressive effect on fertility intentions and behaviours, not all individuals have equally suffered the indirect consequences of the pandemic, and especially those related with the increased uncertainty brought by the economic recession. This study accounts for the heterogeneous consequences of the pandemic on fertility plans and behaviours, by focusing on the motivations for suspended pre-Covid fertility plans and on those for new fertility plans and conceptions that arose during the pandemic. The reasons for the latter are almost unexplored. To do that, we rely on unique data collected with a repeated cross-sectional survey conducted in April/May 2021 and October/November 2021 (2000 respondents each) on a quota sample of young Italians (aged 18 to 34). After exploring the main motivations for changing pre-COVID fertility plans or for intending to conceive a previously unplanned child during the pandemic, we estimate a set of multinomial and logit models to examine some correlates of fertility plans and behaviours. Finally, by interpreting these results in light of the reported motivations, we provide a more qualitative analysis that allows for a deeper interpretation of the reasons behind the patterns of associations. Potentially complex and non-unidirectional mechanisms, only partially related with reducing financial and occupational vulnerability, emerge as relevant for supporting fertility during the pandemic.

This article is devoted to the analysis of the current state of level teaching of the English language in schools of Kazakhstan. The transition to level education in the Republic of Kazakhstan required significant changes in the entire educational process for teaching foreign languages: the introduction of new, more effective teaching technologies that simulate linguistic conditions of the country of the target language, the creation of new documentation, the training of teachers, the development of a new system for assessing student results. The main change was the transition from traditional teaching, focused on teaching grammar and vocabulary, knowledge of the rules of using the language, to teaching based on teaching communication skills, competencies. This article is a study on the impact of the practical application of the CEFR principles, as a recommended document, on the level teaching of the English language in Kazakhstani schools. Our study attempted to examine the impact that CEFR postulates have on teaching and lesson planning practice, and the extent of this change, by examining the practice of English teachers who have participated in CEFR-related advanced training, and professional training related with updated educational content and a communicative approach in teaching foreign languages. The results showed that training, as one of the scientific and methodological conditions for the transition to level education, has a positive impact on the area of planning and teaching. The obtained data show that the transition took place not only formally on paper, but also in classrooms.

Published: May 2022

The main aim of this study was to identify the external monitors' problems and their influence on their performance in monitoring the elementary schools. The research was a sequential explanatory mixed method. All Monitoring and Evaluation Assistants (MEAs) (male and female) working as external monitors in Punjab were the study population. Firstly, districts were randomly selected, and then 4 MEAs from each sampled section were purposively selected. A self-developed questionnaire on the five-point Likert scale and a semi-structured interview were used as study instruments. The qualitative data were coded, themes were developed, and descriptive interpretation was carried out. It is found that external monitors have a burden of work, a lack of conveyance and inspection allowance, and a budget for stationery. They faced political interference and were not satisfied with the training. Consequently, the lack of facilities influences their performance. To improve their performance, these problems may be solved.

Introduction: Chronic kidney disease is defined as structural or functional damage of the kidney persisting for three or more months. Studies have shown hypertension and diabetes as the leading causes of chronic kidney disease. The aim of this study is to find out the prevalence of end-stage renal disease patients undergoing haemodialysis in a tertiary care hospital.
Methods: This was a descriptive cross-sectional study conducted among 96 patients undergoing haemodialysis from February 13, 2021 to April 4, 2021 in the hemodialysis unit of a tertiary care centre after receiving ethical clearance from the Institutional Review Committee (Reference number: 354). Convenience sampling was done and all patients older than 18 years who were on maintenance haemodialysis on an outpatient basis were included in the study. Data were collected using a self-administered questionnaire. Data were analysed using the Statistical Package for the Social Science version 22.0. Point estimate at 95% Confidence Interval was calculated along with frequency and percentages for binary data and mean with standard deviation for continuous data.
Results: Among 96 patients undergoing haemodialysis, the prevalence of end-stage renal disease was 83 (86.45%) (79.60-93.30 at 95% Confidence Interval). The most common underlying condition was hypertensive nephropathy in 34 (40.96%) patients, followed by both hypertensive and diabetic nephropathy in 26 (31.33%) patients.
Conclusions: The prevalence of end-stage renal disease in our study was higher when compared to similar studies conducted in similar settings. Early diagnosis and adequate treatment of hypertension and diabetes could be crucial to reducing the prevalence of the end-stage renal disease.

The article proposes to define competitiveness in the labor market as the ability to be attractive to the able-bodied person at the macro and micro levels and in the short and long term. The aim of the article is to study the competitiveness of the labor market from the standpoint of material incentives and the ability to compete in economic activities. A wide range of criteria characterizing competitiveness in the labor market has been established. It is proposed to outline the level of material incentives by the criterion of competitiveness. The latter should be understood as the correspondence of the growth rate of the average monthly wage to a similar indicator calculated on the basis of the minimum wage. It is proposed to determine the growth rate based on the calculation of earnings indices. Given the characteristics of competitiveness in the labor market in the short term, the calculation of indices should be carried out by the chain method. When considering the long-term perspective, indices are calculated by the basic method. When considering the long-term perspective, indices are calculated by the basic method. The indicator of the level of material incentives is determined by calculating the absolute deviation between the indices of average monthly and minimum wages. It is proposed to determine the study period within three years. The negative trend is considered to be a negative absolute deviation between the indices. In order to characterize the level of competitiveness in the labor market, a scale is proposed, the latter contains the levels: "sufficient", "satisfactory", "unsatisfactory" and "critical". Each level corresponds to a separate condition for the presence of positive and negative values of the absolute deviation between the indices.

This study analyses the importance of the connection between the development of smart agriculture and sustainable digital transformation (DT) of the agri-food sector. The sustainability of DT depends on a number of complex components, especially information and communication technologies (ICT), and economic systems. The increase in the number of studies in this area indicates a complex nature as well as interdependencies. Over the last few decades of innovation, ICT, artificial intelligence (AI) and the Internet of Things (IoT) have significantly affected human activities in all aspects. This includes the rapidly changing and difficult-to-predict agricultural sector in the context of global development, indicating the need to address these challenges. The global trend of DT has included all sectors, opening space for the contribution of smart agriculture to sustainable DT, but also to find appropriate "tailor-made solutions" for every challenge we face.

Big data has unlocked the door to significant advances in a wide range of scientific fields, and it has emerged as a highly attractive subject both in the world of academia and in business as a result. It has also made significant contributions to innovation, productivity gains, and competitiveness enhancements. However, there are many difficulties associated with data collecting, storage, usage, analysis, privacy, and trust that must be addressed at this time. In addition, inaccurate or misleading big data may lead to an incorrect or invalid interpretation of findings, which can negatively impact the consumers' experiences. This article examines the challenges related to implementing big data security and some important solutions for addressing these problems. So, a total of 12 papers have been extracted and analyzed to add to the corpus of literature by concentrating on several critical issues in the big data analytics sector as well as shedding light on how these challenges influence many domains such as healthcare, education, and business intelligence, among others. While studies have proven that big data poses issues, their approaches to overcoming these obstacles vary. The most frequently mentioned challenges were data, process, privacy, and management. To address these issues, this paper included previously discovered solutions.
Exploring Sentiment Analysis on Arabic Tweets about the COIVD-19 Vaccines
Authors: Alsabban Wesam H.
Published: May 2022

The COVID-19 pandemic has imposed a public health crisis across the world. The global efforts lead to the development and deployment of multiple vaccines. The success of ending the COVID-19 pandemic relies on the willingness of people to get the vaccines. Social media platforms prove to be a valuable source to perform experiments on sentiment and emotion towards COVID-19 vaccination in many languages, mainly focusing on English. The people express their opinions and emotion on Twitter briefly, which can have tracked almost instantaneously. This helps the governments, public health officials, and decision-makers to understand public opinions towards vaccines. The goal of this research is to investigate public sentiment on COVID-19 vaccines. Twitter social media extracted all Arabic-language tweets mentioning seven vaccines in 7 months from 1 November 2020 to 31 May 2021. A set of Arabic sentiment lexicons were prepared to perform the sentiment analysis. The tweets' monthly average sentiment were calculated from the collected dataset and evaluated comparatively for each vaccine throughout the 11 months. Out of 5.5 million tweets that have been retrieved using the most frequent keywords and hashtags during the COVID-19 pandemic, 202,427 tweets were only considered and included in the monthly sentiment analysis. We considered tweets that mentioned only one vaccine name of the text. The distribution of tweets shows that 47.5% of the considered tweets mentioned the Pfizer vaccine. It is reported that 64% of the total tweets are non-negative while 35% are negative, with a significant difference in sentiment between the months. We observed an increase of non-negative tweets in parallel with increasing negative tweets on May 2021, reflecting the public's rising confidence towards vaccines. Lexicon-based sentiment analysis is valuable and easy to implement the technique. It can be used to track the sentiment regarding COVID-19 vaccines. The analysis of social media data benefits public health authorities by monitoring public opinions, addressing the people's concerns about vaccines, and building the confidence of individuals towards vaccines.

Published: May 2022

The paper presents a model for predicting the roll wear in the hot rolling process. It includes all indicators from the entire continuous rolling line that best predict the roll wear in the hot rolling process. Data for model development were obtained from annual production on the first rolling stand of the continuous roll mill. The main goal of the research was to determine significant parameters that affect the wear of the roll in the process of hot rolling. It has been found that the amount of rolled material before the re-machining of the roll surface has the greatest impact on the life of the roll contour. Therefore, the amount of material rolled before re-machining of the roll was used to estimate the wear of the roll. An artificial neural network was used to predict this amount of rolled material and was validated using data from one-year production.
