Background and objectives: Waste paper recycling utilization has been increasing in Iran and world paper industries which offers many benefits to the environment and humans. Municipal waste is also reused after recycling processes. Cardboard recycling industry has great environmental and economic importance and helps overcone the lack of wood resources and high demand for paper products. It plays an important role in the development of paper-related industries. However, recycling can be associated with the reduction in the optical properties of the paper. The use of nanoparticles in the paper industry is also expanding gradually. Nanosilica is one of the most important nanoparticles which is used as a retention aid in the paper industry. In order to reduce the consumption of long fibers and obtain the desired optical properties, the use of nanosilica alone or in combination with other materials such as cationic starch and cationic polyacrylamide is investigated. The purpose of this research is to compare the effect of individual and combined use of nanosilica additives, cationic polyacrylamide, cationic starch and long fibers on the optical properties of white liner paper pulp. Methodology: In this study, white paper pulp with the brightness of at least 78% and the gloss of at least 45% was used to prepare handmade paper sheets. Long fiber kraft chemical pulp from coniferous wood imported from Russia with the brightness of 89% was used in the laboratory paper sheet making. Nanosilica powder (NanoSiO2) (Degussa), Germany, cationic polyacrylamide (Farinret K325 brand, Degussa, Germany), and cationic starch (LyckebyAmylex, Slovakia) were used. Independent treatments included the addition of 10% refined long fibers pulp, 6% nanosilica, 1.5% cationic starch and 0.15% cationic polyacrylamide and combined treatments included 6% nanosilica and 1.5% cationic starch and 6% nanosilica and 0.15% cationic polyacrylamide. Then 127 g.m-2 handmade papers were prepared and the optical and microscopic properties were evaluated. Results: The results showed that by adding 10% long fibers, the brightness decreased and by using 6% nanosilica, the maximum brightness was reached. Meanwhile, the whiteness of papers with 6% nanosilica was minimum and with the dosage of only 0.15% cationic polyacrylamide, the whiteness reached at the maximum value. Opacity showed its highest value with the combination of 6% nanosilica and 0.15% cationic polyacrylamide. Also, by increasing the amount of polyacrylamide and cationic starch, individually or in combination with nanosilica, the opacity increased. The light absorption coefficient was the lowest in papers with 6% nanosilica and the light scattering coefficient was the highest in papers containing 6% nanosilica and 0.15% cationic polyacrylamide. A colorimeter was used to measure the color components and the results showed that the additives had an effect on the brightness and whiteness of the papers. Also, changes in the color spectrum and the value of color change were also observed. Additives increased the darkness and changes in different colors. Conclusion: The use of nanosilica individually and in combination with starch and cationic polyacrylamide increases the brightness of papers. Also, the use of cationic polyacrylamide individually and in combination with nanosilica leads to an increase in the whiteness and opacity of papers. The brightness factor of the papers, which is representative of the L* component, decreased with the exception of the addition of 10% long fibers and 6% nanosilica. The amount of overall color change with ΔE* was the lowest in samples containing 1.5% cationic starch and the highest in samples containing 0.15% cationic polyacrylamide. The use of some treatments can lead to a decrease in the optical properties and a decrease in the printability quality of the white liner. To solve this problem, mechanical pulp that has been decolorized or coated on the surface of the paper can be used. The presence of nano-silica particles in the structure of the paper improves the surface structure and reduces the prosity, which results in the reduction of surface roughness and less light refraction, and increases the light reflection and brightness of the paper.

In this interview, Dr. Ozen Guven talks to Dr. Mary Mendenhall, Sonia Gomez, and Emily Varni about their research on teachers and teaching practices in contexts of forced displacement. Mendenhall, Gomez, and Varni recently authored "Teaching Amidst Conflict and Displacement: Persistent Challenges and Promising Practices for Refugee, Internally Displaced, and National Teachers," a background paper for the 2019 Global Education Monitoring Report on the challenges and opportunities available to teachers working in forced displacement settings. Drawing from their paper, which includes case studies from countries as diverse as Germany, Kenya, Chad, and Iraq, the authors discuss such topics as education planning, teacher professional development, teacher well-being and motivation, and teacher agency. Throughout the discussion, they highlight practices and policies that could be leveraged to strengthen support for teachers working in displacement contexts. Mendenhall, Gomez, and Varni are scholar-practitioners whose work focuses on the challenges faced by teachers in crisis contexts, and on the policies and practices that provide these teachers with comprehensive support. Guven's work examines teaching practices among Syrian refugees in Turkey.

The importance of psychological factors is manifested in the ability of students to acquire knowledge, gaining skills, perception of educational information, attitude to others, mutual understanding with people around. Taking this into consideration, the purpose of the academic paper is to study the basic aspects of the development of teachers' professional competence in the context of transformational processes in education. Such methods as: theoretical analysis, description, comparison, synthesis, grouping, measurement, observation and experiment, have been used in order to achieve the purpose and objectives outlined in the academic paper. It has been established that the motivation of students to carry out educational and professional activities is a set of psychological factors, through the influence of which the interconnection between the motivation and desire of the student to study is conducted. In the course of the investigation, it has been found that the influence of psychological factors is quite effective in the case of motivating students to study. It has been proven that increasing the motivation of students to study is possible through: a common learning environment in the students' collective; students' participation in discussions, conferences, competitions; work in groups; application of innovative technological methods of studying educational material.

Involving the global issues as listed in Sustainable Development Goals (SDGs) in education is necessarily done in the education process, especially in English as a Foreign Language (EFL) learning. Exposure to global issues is known to improve students' understanding, awareness, and ability to solve urgent issues faced by global society. This paper aims to find out the trend of research on the coverage of SDGs in students' learning process. This systematic literature analysis was done by applying Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Method. A total of 25 studies were recognized through a systematic search by using Sustainability, SDGs, and EFL as keywords. The result shows that the trend of associating SDGs with EFL settings was done mostly in Indonesia. In the recent year 2022, it reached the highest number of studies in the particular matter with 7 total of research. It was also found that the study involving SDGs on EFL learning was mostly done in the tertiary setting, compared with K-12, junior high school, secondary, high school, and other educational institutions. It was also discovered that the specific area of study enhances EFL students' learning achievement, environmental awareness, global citizen values, as well as students' levels of self-norms, beliefs, and self-value.

Water governance systems have evolved around the exploitation of provisioning ecosystem services. The overexploitation of provisioning and the degradation of regulating services have led to a decline in the capacity of ecosystems to provide any services at all. Decisions affecting water-related ecosystem services are often not made in the water sector. Governance that does not take into account ecological interdependencies lead to unsustainable use of resources. In such situations, one can speak of a misfit between interdependencies of ecosystem services and coordination processes that would allow addressing them. The article introduces an approach to identify such misfits and potential solutions to overcome them and applies the approach to case studies in Germany, South Africa and Iran. The context-sensitive analyses highlight factors that contribute to or even determine prevailing practices in water management. The fit with the pattern of ecosystem service uses was found to be higher for governance processes in practice (formal and informal) than for formal coordination instruments on paper. Actors may not lack opportunities to exchange but these are not translated into tangible coordination outcomes. To reduce trade-offs between the uses of ecosystem service, improved synergies are needed between formal and informal institutional settings. Instruments need to be tailored to local circumstances. Scope and effectiveness of local action may be limited by higher governance levels. The analyses have demonstrated that the path from improving social-ecological fit to achieving sustainability is long. Addressing institutional deficits requires transformational change rather than short-term measures for addressing isolated problems or crisis situations. • New approach to identify misfits between ecosystem services uses and coordination and potential solutions to overcome them. • Results from case studies in Germany, South Africa and Iran. • Synergies needed between formal and informal institutional at local level to reduce trade-offs between ecosystem services.

In this study, the variables having impact on the student motivation have been analyzed based on the articles, conference papers, master's theses and doctoral dissertations published in the years 2000-2017. A total of 165 research papers were selected for the research material and the data were collected through qualitative research techniques through document review and content analysis. According to the research results, the most important factors affecting student motivation are the fields of teacher, teachers' classroom management skills and their teaching methods. In this research, factors having less influence on the student motivation are parental communication, student characteristics and study fields. In addition, relational search type was used more than others, mostly students were selected as the study group and most researches were conducted in USA and Turkey.

This article maps the scientific production and the contents associated with the sustainable development goals and their integration with universities during the past 21 years. Although many of the topics related to sustainable development goals (SDGs) have been addressed in different studies for decades, it is since 2015 onwards that they gained greater prominence due to the inclusion of higher education as an important actor in the fulfillment of the 2030 agenda and the United Nations SDGs. For the purpose of this paper, a bibliometric analysis of 871 papers, 535 documents in Scopus, and 336 in Web of Science (WoS) from 1998 to 2019 was performed, and the Bibliometrix analysis tool was used. The objective of this mapping is to answer the following research question: Is the integration of the Sustainable Development Goals and Universities a field of study? An analysis of the network of collaborators and trend topics in Scopus and WoS allows us to identify the concurrence and relationships of some keywords, such as sustainable development, sustainability and planning, and some background words, such as humans and global health. In another analysis, the word "higher education" is related to change. This article suggests that the integration of the Sustainable Development Goals in Universities is becoming a field of study under exploration, with a peak of production in 2016 and that has remained stable in the last three years, but thanks to the leading role assigned to Universities, intellectual production should increase in the following years.

This paper reports preliminary findings on students enrolled in a massive open online course, who were also assigned to work in groups. Part of a larger study on the effect of groups on retention and completion in MOOCs, the paper provides students' demographics (i.e., location, gender, education level, and employment status), and motivation for taking the course. Findings show that women outnumbered men and that students mostly enrolled into the course because of a friend. Indeed, research on MOOCs demonstrates that men outnumber women and that educational pursuit and professional development are the main motivators for taking MOOCs. Yet, this paper shows that when group work is included in a MOOC, women participate more. Furthermore, for students assigned to groups in a MOOC, friends are the principal incentive for enrolling into the course. These results are discussed in light of previous research, and implications for teaching and learning in online environments addressed.

Background: Patient safety in primary care is an emerging field of research with a growing evidence base in western countries but little has been explored in the Gulf Cooperation Council Countries (GCC) including the Sultanate of Oman. This study aimed to review the literature on the safety culture and patient safety measures used globally to inform the development of safety culture among health care workers in primary care with a particular focus on the Middle East. Methods: A systematic review of the literature. Searches were undertaken using Medline, EMBASE, CINAHL and Scopus from the year 2000 to 2014. Terms defining safety culture were combined with terms identifying patient safety and primary care. Results: The database searches identified 3072 papers that were screened for inclusion in the review. After the screening and verification, data were extracted from 28 papers that described safety culture in primary care. The global distribution of the articles is as follows: the Netherlands (7), the United States (5), Germany (4), the United Kingdom (1), Australia, Canada and Brazil (two for each country), and with one each from Turkey, Iran, Saudi Arabia and Kuwait. The characteristics of the included studies were grouped under the following themes: safety culture in primary care, incident reporting, safety climate and adverse events. The most common theme from 2011 onwards was the assessment of safety culture in primary care (13 studies, 46%). The most commonly used safety culture assessment tool is the Hospital survey on patient safety culture (HSOPSC) which has been used in developing countries in the Middle East. Conclusions: This systematic review reveals that the most important first step is the assessment of safety culture in primary care which will provide a basic understanding to safety-related perceptions of health care providers. The HSOPSC has been commonly used in Kuwait, Turkey, and Iran. [ABSTRACT FROM AUTHOR]

Objective Because of the increasing number of people with disabilities and the lack of awareness of disability prevention methods in developing countries, creating a proper rehabilitation structure and providing appropriate services are among the important goals of every health system. Conducting comparative studies is one of the research methods for reviewing the structure of the rehabilitation system in the country's health system. This study aimed to compare the rehabilitation structure in Iran with 5 other countries. Materials & Methods This research is a comparative study conducted in 2022. In this study, sampling was purposeful. Five countries of Germany, Japan, Canada, Turkey, and South Africa were compared in terms of organizational and health management, financial and legal components, and social policy components with Iran. Reliable databases and related resources in the rehabilitation structure were used to collect data. In this study, the obtained data were analyzed using the Bereday model containing four stages: Description, interpretation, proximity, and comparison. The findings were evaluated in a comparative table. Results The findings indicated that in terms of organization and health management, the Ministry of Health should be responsible for health management and rehabilitation, but in Iran, in addition to the Ministry of Health, the Red Crescent, the Martyr Foundation, and Exceptional Education Organization are also involved in the management of rehabilitation. Financial issues and problems are significant barriers for people with disabilities to access rehabilitation services in these countries. In Iran, a large part of these costs is paid from the pockets of families. Regarding legal components in Iran, as in other countries, specific rules exist to provide services to people with disabilities. But sometimes, these rules are not properly implemented. From the sociodemographic perspective, Iran has an aging population, welcomes immigrants, and holds diverse cultures. The access of all people in need of rehabilitation in this diverse population to the services needed is limited. In terms of policy components, regulating national health policy requires review and, if necessary, changes in existing health system policies. Conclusion The existence of a specific position for rehabilitation in the Iranian health system, provision of services, and management of rehabilitation affairs by a single organization such as the Ministry of Health, as well as proper implementation of laws and policies, can lead to structural improvement and management of the health system and rehabilitation. Financial obstacles and problems to rehabilitation services should be reduced, and government and insurance must cover most of the costs of rehabilitation services. Also, a review of national health policies and legislation in the country should be done to improve the access of all people with disabilities to health and rehabilitation services. Therefore, it is necessary to fundamentally review and reform the structure, value, and process of providing rehabilitation services. [ABSTRACT FROM AUTHOR]

Social innovations for sustainable consumption have attracted policymakers' attention internationally as a possible means to reach sustainability and climate change goals. So far, most of the research on the emergence and potential of social innovations has been carried out in the Global North. Consequentially, some theoretical approaches and concepts have not been reviewed critically for their applicability in other contexts. This paper explores similarities and differences in the emergence and development process of social innovations for sustainable consumption in different cultural and geographical contexts to fill this gap. The objective is to enrich current concepts with more context-sensitive categories. On this account, the paper undertakes an explorative qualitative cross-country analysis of innovations for sustainable consumption in diverse sectors, using a sample of 87 cases collected by desk research in Brazil, Germany, and Iran. The analysis is based on a procedural perspective on innovation and refers to the three phases problematization, experimentation, and restabilization. The research shows that, in the problematization phase, the initiatives differ in taking up "globalized" challenges affecting most countries worldwide versus "locally emerged" ones, more connected to socio-economic, cultural, or political specifics. Experimentation with possible solutions differentiates between "imported" versus "locally" invented or appropriated context-specific approaches. Forms and degrees of restabilization depend mainly on framings for start-ups or non-governmental organizations and the local government's openness for innovative approaches. Based on the manifestation of these characteristics, the analyses result in four different qualitative types. The identified categories complement existing typologies, which so far neglect the geopolitical scope of the addressed problems and the tested solutions. Further empirical analyses in different countries will show whether the identified categories and types are helpful for a better understanding of the emergence and development of social innovations for sustainable consumption in different socio-economic, geopolitical, and cultural contexts. • The analytical framework combines the phenomena of sustainable consumption with the three phases of the innovation process. • Social innovations for sustainable consumption differ in their reaction to global or local challenges. • The solutions to global and local challenges can be imported, locally invented, or appropriated context-specific approaches.

During the outbreak of a disease caused by a pathogen with unknown characteristics, the uncertainty of its progression parameters can be reduced by devising methods that, based on rational assumptions, exploit available information to provide actionable insights. In this study, performed a few (~6) weeks into the outbreak of COVID-19 (caused by SARS-CoV-2), one of the most important disease parameters, the average time-to-recovery, was calculated using data publicly available on the internet (daily reported cases of confirmed infections, deaths, and recoveries), and fed into an algorithm that matches confirmed cases with deaths and recoveries. Unmatched cases were adjusted based on the matched cases calculation. The mean time-to-recovery, calculated from all globally reported cases, was found to be 18.01 days (SD 3.31 days) for the matched cases and 18.29 days (SD 2.73 days) taking into consideration the adjusted unmatched cases as well. The proposed method used limited data and provided experimental results in the same region as clinical studies published several months later. This indicates that the proposed method, combined with expert knowledge and informed calculated assumptions, could provide a meaningful calculated average time-to-recovery figure, which can be used as an evidence-based estimation to support containment and mitigation policy decisions, even at the very early stages of an outbreak.

Cultural and biographical influences on the expression of emotions manifest themselves in so-called "display rules." These rules determine the time, intensity, and situations in which an emotion is expressed. To date, only a small number of empirical studies deal with this transformation of how migrants, who are faced with a new culture, may change their emotional expression. The present, cross-sectional study focuses on changes in anger expression as part of a complex acculturation process among Iranian migrants. To this end, Iranian citizens in Iran (n = 61), German citizens (n = 61), and Iranian migrants in Germany (n = 60) were compared in terms of anger expression behavior and acculturation strategy (assimilation, separation, integration, marginalization) was assessed among the migrants, using the Frankfurt Acculturation Scale (FRACC). A questionnaire developed in a preliminary study was used to measure anger expression via subjective anger experience and anger expression within 16 hypothetical situations. Multivariate Analyses of Variance (MANOVA) revealed that Iranians and Iranian migrants reported higher anger experience ratings than Germans and directed their anger more often inward (anger-in). Further findings suggest that transformation processes may have affected Iranian migrants in terms of suppressed anger (anger-in): Iranian migrants with a higher orientation toward German culture reported lower average anger-in scores. These results suggest that there was different emotional expression among Iranian migrants, depending on their acculturation. The results provide new insight into socio-cultural and individual adjustment processes. [ABSTRACT FROM AUTHOR]

The idea that the past holds lessons for the present, under the guise of historical analogies, is prevalent in political and public discourse. Those analogies are often accompanied by dire warnings befalling those who "forget" or otherwise neglect the powerful lessons of History--and would then be "doomed to repeat it", as the saying goes. So, Would remembering history make it seem more or less likely to repeat itself in the future? In other words, does exposure to specific lessons about past events, especially ones involving causal claims, affect how people expect real-life events to turn out? Four studies (three preregistered) tested this experimentally. In Studies 1 and 2, participants expected the same behavior (the US adopting a harsh stance against Iran in the Nuclear Treaty) to result in a more negative outcome when this current stance seemed to match a "lesson" they had read about the break-out of World War II (European leaders adopting a harsh approach against Germany in the 1919 Versailles Treaty vs. a conciliatory approach in the 1938 Munich Agreement). Studies 3 and 4 attempted to eliminate some confounds present in the first two studies and to generalize the effect to different events. While results varied across studies, an internal meta-analysis indicated that the analogical effect on predictions (d = -.08) tended to become stronger as participants' knowledge about the target situation decreased (d-1SD = -.24). These findings support the possibility of analogical-based predictive effects for real-life political events, and are discussed in light of their research and political implications.

Abstract: To improve the energy efficiency of buildings via compliance to regulation in Iran, Code No. 19 was devised in 1991. The code lacks high level aims and objectives, addressing the characteristics of Iranian buildings. As a consequence, the code has been revised and is not completely implemented in practice, and still remains inefficient. As with any energy coding system, this code has to identify the right balance between the different energy variables for the Iranian climate and way of life. In order to assist improvements to high level objectives of Code 19, this code is compared with ISO 9164, EN 832, German regulation, TS 825 of Turkey and China’s GB 50189 to understand how these have adapted international standards to national features. In order to test the appropriateness of Code 19, five case study buildings in Iran are assessed against Code 19 as well as Turkish standard TS 825 and the results are compared. The results demonstrate that Code 19 is efficient in calculations of building envelope, but it needs improvements in the areas of ventilation, gains from internal and solar sources. The paper concludes by offering suggestions for improving the code. [Copyright &y& Elsevier]

Introduction:Recurrent aphthous ulcers are the most common pathologic conditions of the oral cavity, which despite having clear clinical features, the etiology is unknown. This study aimed to determine the relationship between one of the histocompatibility antigens (HLA DRB1) and its sub-groups with the incidence of recurrent aphthous ulcers in an Iranian population (North East of Iran). Methods: In this case-control study, a total of 72 patients with recurrent aphthous ulcers and 70 healthy subjects in Northeast Iranian population were included. Genotyping was done by polymerase chain reaction-specific sequence primers (PCRSSP) for each sample, according to standard kit protocol (BAG- Germany). Results: In 72 patients with recurrent aphthous ulcers that were included in this study, 26 were male and 46 were female; of the 70 control patients, this difference not significant statistically (P>0.05). The frequency of HLA -DRB1 *16 was 0.7% in the healthy subjects, however frequency of HLA -DRB1 *16 in patients with recurrent aphthous stomatitis (RAS) was 42.36%, and this difference was statistically significant (P=0.03). But, this difference was not observed in other subgroups. Conclusion: The frequency of DRB1 * 16 in the patients with RAS were higher than the group. Therefore, DRB1 * 16 can be suggested as a Predisposing factor for aphthous ulcers patients. [ABSTRACT FROM AUTHOR]

Background: The year 2016 has marked the highest number of displaced people worldwide on record. A large number of these refugees are women, yet little is known about their specific situation and the hurdles they have to face during their journey. Herein, we investigated whether sociodemographic characteristics and traumatic experiences in the home country and during the flight affected the quality of life of refugee women arriving in Germany in 2015-2016.Methods: Six hundred sixty-three women from six countries (Afghanistan, Syria, Iran, Iraq, Somalia, and Eritrea) living in shared reception facilities in five distinct German regions were interviewed by native speakers using a structured questionnaire. Sociodemographic data and information about reasons for fleeing, traumatic experiences, symptoms, quality of life, and expectations towards their future were elicited. All information was stored in a central database in Berlin. Descriptive analyses, correlations, and multivariate analyses were performed.Results: The most frequent reasons cited for fleeing were war, terror, and threat to one's life or the life of a family member. Eighty-seven percent of women resorted to smugglers to make the journey to Europe, and this significantly correlated to residence in a war zone (odds ratio (OR) = 2.5, 95% confidence interval (CI) = 1.4-4.6, p = 0.003) and homelessness prior to fleeing (OR = 2.1, 95% CI = 1-4.3, p = 0.04). Overall the described quality of life by the women was moderate (overall mean = 3.23, range of 1-5) and slightly worse than that of European populations (overall mean = 3.68, p < 0.0001). The main reasons correlating with lower quality of life were older age, having had a near-death experience, having been attacked by a family member, and absence of health care in case of illness.Conclusions: Refugee women experience multiple traumatic experiences before and/or during their journey, some of which are gender-specific. These experiences affect the quality of life in their current country of residence and might impact their integration. We encourage the early investigation of these traumatic experiences to rapidly identify women at higher risk and to improve health care for somatic and mental illness. [ABSTRACT FROM AUTHOR]

ACADEMIC EMERGENCY MEDICINE 2011; 18:1358-1370 © 2011 by the Society for Academic Emergency Medicine Abstract The maturation of emergency medicine (EM) as a specialty has coincided with dramatic increases in emergency department (ED) visit rates, both in the United States and around the world. ED crowding has become a public health problem where periodic supply and demand mismatches in ED and hospital resources cause long waiting times and delays in critical treatments. ED crowding has been associated with several negative clinical outcomes, including higher complication rates and mortality. This article describes emergency care systems and the extent of crowding across 15 countries outside of the United States: Australia, Canada, Denmark, Finland, France, Germany, Hong Kong, India, Iran, Italy, The Netherlands, Saudi Arabia, Catalonia (Spain), Sweden, and the United Kingdom. The authors are local emergency care leaders with knowledge of emergency care in their particular countries. Where available, data are provided about visit patterns in each country; however, for many of these countries, no national data are available on ED visits rates or crowding. For most of the countries included, there is both objective evidence of increases in ED visit rates and ED crowding and also subjective assessments of trends toward higher crowding in the ED. ED crowding appears to be worsening in many countries despite the presence of universal health coverage. Scandinavian countries with robust systems to manage acute care outside the ED do not report crowding is a major problem. The main cause for crowding identified by many authors is the boarding of admitted patients, similar to the United States. Many hospitals in these countries have implemented operational interventions to mitigate crowding in the ED, and some countries have imposed strict limits on ED length of stay (LOS), while others have no clear plan to mitigate crowding. An understanding of the causes and potential solutions implemented in these countries can provide a lens into how to mitigate ED crowding in the United States through health policy interventions and hospital operational changes.

Since Kermack and McKendrick have introduced their famous epidemiological SIR model in 1927, mathematical epidemiology has grown as an interdisciplinary research discipline including knowledge from biology, computer science, or mathematics. Due to current threatening epidemics such as COVID-19, this interest is continuously rising. As our main goal, we establish an implicit time-discrete SIR (susceptible people–infectious people–recovered people) model. For this purpose, we first introduce its continuous variant with time-varying transmission and recovery rates and, as our first contribution, discuss thoroughly its properties. With respect to these results, we develop different possible time-discrete SIR models, we derive our implicit time-discrete SIR model in contrast to many other works which mainly investigate explicit time-discrete schemes and, as our main contribution, show unique solvability and further desirable properties compared to its continuous version. We thoroughly show that many of the desired properties of the time-continuous case are still valid in the time-discrete implicit case. Especially, we prove an upper error bound for our time-discrete implicit numerical scheme. Finally, we apply our proposed time-discrete SIR model to currently available data regarding the spread of COVID-19 in Germany and Iran. [ABSTRACT FROM AUTHOR]

Background : Parenting interventions based on emotion socialization (ES) theory offer an important theoretically driven approach to improve children's emotional competence and behavioral functioning. Whether such approaches are effective in different cultural contexts, and whether the methods of delivery used are appropriate and acceptable, is an important empirical question. This paper reports on the preliminary evaluation of an ES parenting intervention, Tuning in to Kids (TIK), in Germany, Turkey, Iran, and China. Pilot studies of TIK have been conducted in each country with mothers of 4-6-year-old children. Method: The current study used qualitative methods with thematic analysis to explore the cultural appropriateness of the program in each site. Results: Culture-specific challenges were found across all sites in changing parents' beliefs about the value of encouraging children's emotional expression and supportive emotion discussions. Emotion literacy of parents depended on their access to emotion terms in their language, but also to parents' experiences with emotions in their family of origin and culture-related beliefs about emotions. Adaptations were required to slow the speed of delivery, to address issues of trust with parents in seeking help, and to provide more opportunities to practice the skills and integrate different beliefs about parenting. Conclusion : While this ES parenting intervention has been developed in a Western cultural context, slight adaptations to the delivery methods (rather than change to the content) appeared to contribute to cultural appropriateness. The next step will be to quantitatively evaluate these adaptations of TIK in the different countries using randomized controlled studies.
