- Background: Population estimates underpin demographic and epidemiological research and are used to track progress on numerous international indicators of health and development. To date, internationally available estimates of population and fertility, although useful, have not been produced with transparent and replicable methods and do not use standardised estimates of mortality. We present single-calendar year and single-year of age estimates of fertility and population by sex with standardised and replicable methods. Methods: We estimated population in 195 locations by single year of age and single calendar year from 1950 to 2017 with standardised and replicable methods. We based the estimates on the demographic balancing equation, with inputs of fertility, mortality, population, and migration data. Fertility data came from 7817 location-years of vital registration data, 429 surveys reporting complete birth histories, and 977 surveys and censuses reporting summary birth histories. We estimated age-specific fertility rates (ASFRs; the annual number of livebirths to women of a specified age group per 1000 women in that age group) by use of spatiotemporal Gaussian process regression and used the ASFRs to estimate total fertility rates (TFRs; the average number of children a woman would bear if she survived through the end of the reproductive age span [age 10–54 years] and experienced at each age a particular set of ASFRs observed in the year of interest). Because of sparse data, fertility at ages 10–14 years and 50–54 years was estimated from data on fertility in women aged 15–19 years and 45–49 years, through use of linear regression. Age-specific mortality data came from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 estimates. Data on population came from 1257 censuses and 761 population registry location-years and were adjusted for underenumeration and age misreporting with standard demographic methods. Migration was estimated with the GBD Bayesian demographic balancing model, after incorporating information about refugee migration into the model prior. Final population estimates used the cohort-component method of population projection, with inputs of fertility, mortality, and migration data. Population uncertainty was estimated by use of out-of-sample predictive validity testing. With these data, we estimated the trends in population by age and sex and in fertility by age between 1950 and 2017 in 195 countries and territories. Findings: From 1950 to 2017, TFRs decreased by 49·4% (95% uncertainty interval [UI] 46·4–52·0). The TFR decreased from 4·7 livebirths (4·5–4·9) to 2·4 livebirths (2·2–2·5), and the ASFR of mothers aged 10–19 years decreased from 37 livebirths (34–40) to 22 livebirths (19–24) per 1000 women. Despite reductions in the TFR, the global population has been increasing by an average of 83·8 million people per year since 1985. The global population increased by 197·2% (193·3–200·8) since 1950, from 2·6 billion (2·5–2·6) to 7·6 billion (7·4–7·9) people in 2017; much of this increase was in the proportion of the global population in south Asia and sub-Saharan Africa. The global annual rate of population growth increased between 1950 and 1964, when it peaked at 2·0%; this rate then remained nearly constant until 1970 and then decreased to 1·1% in 2017. Population growth rates in the southeast Asia, east Asia, and Oceania GBD super-region decreased from 2·5% in 1963 to 0·7% in 2017, whereas in sub-Saharan Africa, population growth rates were almost at the highest reported levels ever in 2017, when they were at 2·7%. The global average age increased from 26·6 years in 1950 to 32·1 years in 2017, and the proportion of the population that is of working age (age 15–64 years) increased from 59·9% to 65·3%. At the national level, the TFR decreased in all countries and territories between 1950 and 2017; in 2017, TFRs ranged from a low of 1·0 livebirths (95% UI 0·9–1·2) in Cyprus to a high of 7·1 livebirths (6·8–7·4) in Niger. The TFR under age 25 years (TFU25; number of livebirths expected by age 25 years for a hypothetical woman who survived the age group and was exposed to current ASFRs) in 2017 ranged from 0·08 livebirths (0·07–0·09) in South Korea to 2·4 livebirths (2·2–2·6) in Niger, and the TFR over age 30 years (TFO30; number of livebirths expected for a hypothetical woman ageing from 30 to 54 years who survived the age group and was exposed to current ASFRs) ranged from a low of 0·3 livebirths (0·3–0·4) in Puerto Rico to a high of 3·1 livebirths (3·0–3·2) in Niger. TFO30 was higher than TFU25 in 145 countries and territories in 2017. 33 countries had a negative population growth rate from 2010 to 2017, most of which were located in central, eastern, and western Europe, whereas population growth rates of more than 2·0% were seen in 33 of 46 countries in sub-Saharan Africa. In 2017, less than 65% of the national population was of working age in 12 of 34 high-income countries, and less than 50% of the national population was of working age in Mali, Chad, and Niger. Interpretation: Population trends create demographic dividends and headwinds (ie, economic benefits and detriments) that affect national economies and determine national planning needs. Although TFRs are decreasing, the global population continues to grow as mortality declines, with diverse patterns at the national level and across age groups. To our knowledge, this is the first study to provide transparent and replicable estimates of population and fertility, which can be used to inform decision making and to monitor progress.

- Identifying driving maneuvers plays an essential role on-board vehicles to monitor driving and driver states, as well as off-board to train and evaluate machine learning algorithms for automated driving for example. Maneuvers can be characterized by vehicle kinematics or data from its surroundings including other traffic participants. Extracting relevant maneuvers therefore requires analyzing time-series of (i) structured, multi-dimensional kinematic data, and (ii) unstructured, large data samples for video, radar, or LiDAR sensors. However, such data analysis requires scalable and computationally efficient approaches, especially for non-annotated data. In this paper, we are presenting a maneuver detection approach based on two variants of space-filling curves (Z-order and Hilbert) to detect maneuvers when passing roundabouts that do not use GPS data. We systematically evaluate their respective performance by including permutations of selections of kinematic signals at varying frequencies and compare them with two alternative baselines: All manually identified roundabouts, and roundabouts that are marked by geofences. We find that encoding just longitudinal and lateral accelerations sampled at 10 Hz using a Hilbert space-filling curve is already successfully identifying roundabout maneuvers, which allows to avoid the use of potentially sensitive signals such as GPS locations to comply with data protection and privacy regulations like GDPR.

- Background: Older people abuse includes intentional or unintentional conduct or omission of a specific behavior by a trusted person that causes injury or distress to older people. This study described older peoples' perceptions of abuse in Iranian society.Methods: This qualitative study applied a conventional content analysis method to understand the perceptions of abuse among older Iranian people. Twenty older residents were selected by purposeful sampling. Data were collected through in-depth, semi-structured, and face-to-face interviews. The six-step Graneheim and Lundman content analysis method guided data analysis. MAXQDA software version 10 was used to manage the data.Results: The data analysis led to the identification of three main themes: broken toughness, hidden abuse, and exploitation. The first theme had two sub-themes: domination and disturbed peace and tranquility.Conclusion: Abuse resulted from a combination of causes and factors. Abuse was hidden in many cases and was not limited to physical abuse. The other examples of abuse included disrespect, deprivation of authority, disturbed tranquility, and financial exploitation of older adults.

- The study aimed to explore the conditions that accompany conflict of conscience experienced by nurses in intensive care units. A qualitative approach guided the study, which was undertaken between April 2020 and April 2021. A total of 15 registered nurses working in intensive care units were recruited through purposive sampling. Individual semistructured interviews were conducted. The data were analyzed using a qualitative content analysis. The analysis revealed two themes: "conflict of conscience in relation to the structure" and "conflict of conscience based on context." Conflict of conscience in relation to the structure consisted of two categories: conflict of interest and conflict of conscience and law. Conflict of conscience based on context consisted of two categories: care dilemmas and arbitrary behaviors with end-stage patients. A variety of factors were accompanied by a conflict of conscience for nurses in intensive care units. Given that conflict of conscience has negative consequences for the health and quality of nursing care, health care managers need to tailor strategies to reduce the negative consequences considering the findings of the study.

- Working as a nurse in the critical care unit may involve ethical challenges including conflict of conscience. Literature provides very limited knowledge about intensive care unit (ICU) nurses' perception of conscience. Considering the influence of culture on the perception of conscience, it is important to study it in diverse contexts. This study aims were to explore the meaning of conscience and the impact of conscience on nurses' practice in the ICU. A qualitative research approach was used to answer the research question, and qualitative content analysis guided the study. A total of 17 interviews were conducted with ICU nurses. Data were collected through semistructured tools by using videoconferencing and face-to-face interviews. Data analysis resulted in the formation of 2 main categories and 7 subcategories. The main categories included understanding the conscience and unlimited efforts in caretaking as the path to a clear conscience. The category of understanding the conscience includes 3 subcategories of conscience as an intrinsic asset and internal observer, dynamicity of conscience, and conscience as the cornerstone of morality. Also, the category of unlimited efforts in caretaking as the path to a clear conscience consists of 4 subcategories including giving full attention to the patient, putting oneself in another's shoes, taking responsibility, and working beyond the job description. Conscience plays an essential role in providing the ethical care among ICU nurses. The ICU nurses felt that they need to go above and beyond to keep their conscience clear. Nurses expressed the importance of following the call of conscience at their workplace, which demanded unlimited efforts to achieve a clear conscience.

- AIM: This study was conducted to explore the factors affecting nurses' intentions to leave or stay in their profession during the coronavirus pandemic in Iran.INTRODUCTION: Because the effectiveness of a healthcare response to a disaster depends on an available, skilled, and motivated healthcare workforce, it is essential to understand and address potential barriers to and reasons for the intentions of medical staff to leave or stay in their profession.METHODS: A qualitative study with a conventional content analysis approach was conducted. The participants included nurses working in hospitals during the COVID-19 pandemic, and nurses who had previously left their job or had been absent from work for a period of time. The participants were selected using a purposeful sampling strategy. Data were collected through 19 in-depth, individual semi-structured interviews with 16 nurses. The COnsolidated criteria for REporting Qualitative research checklist was used to report the study.FINDINGS: Three categories; commitment and work conscience (with a subcategory of risk-taking), fear (with two subcategories of fear of family infection and fear of protective equipment shortages), and organizational factors (with two subcategories of organizational atmosphere of the hospital and motivational factors), emerged from the analysis.CONCLUSION: The reasons for quitting a nursing job or to keep working as a nurse during the pandemic include both personal and organizational factors. Commitment and work conscience in pandemic conditions is one of the main factors for keeping nurses in their profession.IMPLICATION FOR NURSING PRACTICE AND POLICY: Gaining insight into nurses' understanding of the situation and perspectives is the key to being able to provide appropriate support and keep them in the workforce. Peer support can play an important role in supporting novice nurses in facing challenges posed by a pandemic and should be improved. Also, programs and strategies need to be planned to improve resilience among nurses and to help them to manage their stress and fear.
