RESUMEN

This paper examines the influence of housing wealth on fertility outcomes through a regression discontinuity design based on a 2006 Chinese housing-market policy. Our analysis reveals that the positive impact of this policy on housing wealth significantly enhances the likelihood of fertility by 7.3 %. Our result implies that a 1 % increase in housing wealth can raise the fertility rate by 0.18 %. Furthermore, we observe that children born subsequent to the positive housing wealth shock exhibit improved health, not only at birth but also over the long term. Lastly, we present suggestive evidence suggesting that both parental pre-birth time allocation and parental health may help explain the documented positive effects of housing wealth on fertility rates.

RESUMEN

How to allocate study time is an important decision-making problem learners face. Research on this problem can help improve the learning performance of learners and provide guidance for teaching activities. This research aimed to explore the potential of anchors (prior information that may influence individual decision-making and judgment under uncertainty) as clues for study time allocation and examine the effectiveness of study time allocation under the influence of anchors. Sixty-two Chinese university students (Mage = 21.21, SD = 1.74; 44 females) studied 20 word pairs under self-paced learning instructions. These instructions either set a high anchor (i.e., the typical participant spent 15 s learning each pair) or a low anchor (i.e., the typical participant spent 5 s learning each pair) for study time. After a brief distraction phase, participants took a cued recall test. The results showed that the higher the anchor value, the longer the corresponding study time, and the longer the study time, the better the memory performance. These results reveal that there is both an anchoring effect and a labor-and-gain effect in self-paced study time allocation. This study extends the range of observable anchoring effects and provides important information on allocating study time effectively.

RESUMEN

This paper studies the association of pain with subjective well-being (SWB) and time use among older adults in five low- and middle-income countries using data from the first wave of the WHO Study on Global Ageing and Adult Health. We suggest a novel use of anchoring vignettes as direct control functions to account for potentially correlated reporting behaviors such as correlated response scales when analyzing the relationship between subjective variables such as self-reported pain and SWB. Exploiting detailed data on individual time use and several complementary measures of SWB, including fine-grained activity-specific affective experiences derived from an abbreviated version of the Day Reconstruction Method, we find that both evaluative and experienced well-being are markedly lower for people living with pain compared to those without pain. These disparities persist even after controlling for possible confounding from reporting behaviors through the use of anchoring vignettes. Differences in experienced utility by pain status appear to be exclusively due to worse affective experiences during daily activities for those with pain, which seem to be partially mediated through changes in their functional limitations. Pain-related differences in time use, in turn, seem to provide only small compensating effects, underscoring important challenges to the use of changed activity patterns as a viable coping strategy for individuals enduring pain.

RESUMEN

PURPOSE: We evaluated impact on length of stay and possible complications of replacing the Clinical Institute Withdrawal Assessment-Alcohol Revised (CIWA-Ar) scale with a slightly modified Richmond Agitation and Sedation Scale (mRASS-AW) to support managing patients admitted with alcohol withdrawal symptoms in a community hospital. Since mRASS-AW is viewed as easier and quicker to use than CIWA-Ar, provided use of mRASS-AW does not worsen outcomes, it could be a safe alternative in a busy ED environment and offer an opportunity to release nursing time to care. METHODS: Retrospective time-series analysis of mean quarterly length of stay. All analyses exclusively used our hospital's administrative discharge diagnoses database. During April 1st 2012 to December 14th 2014, the CIWA-Ar was used in the ED and in-patient units to guide benzodiazepine dosing decisions for alcohol withdrawal symptoms. After this point, CIWA-Ar was replaced with mRASS-AW. Data was evaluated until December 31st 2020. PRIMARY OUTCOME: mean quarterly length of stay. SECONDARY OUTCOMES: delirium, intensive care unit (ICU) admission, other post-admission complications, mortality. RESULTS: N = 1073 patients. No association between length of stay and scale switch (slope change 0.3 (95% CI - 0.03 to 0.6), intercept change, 0.06 (- 0.03 to 0.2). CIWA-Ar (n = 317) mean quarterly length of stay, 5.7 days (95% 4.2-7.1), mRASS-AW (n = 756) 5.0 days (95% CI 4.3-5.6). Incidence of delirium, ICU admission or mortality was not different. However, incidence of other post-admission complications was higher with CIWA-Ar (6.6%) than mRASS-AW (3.4%) (p = 0.020). CONCLUSIONS: This was the first study to compare patient outcomes associated with using mRASS-AW for alcohol withdrawal symptoms outside the ICU. Replacing CIWA-Ar with mRASS-AW did not worsen length of stay or complications. These findings provide some evidence that mRASS-AW could be considered an alternative to CIWA-Ar and potentially may provide an opportunity to release nursing time to care.

ABSTRAIT: BUT: Nous avons évalué l'impact sur la durée du séjour et les complications possibles du remplacement de l'échelle Clinical Institute Withdrawal Assessment- Alcohol Revised (CIWA-Ar) par une échelle d'agitation et de sédation de Richmond légèrement modifiée (mRASS-AW) soutenir la prise en charge des patients admis avec des symptômes de sevrage d'alcool dans un hôpital communautaire. Étant donné que le mRASS-AW est considéré comme plus facile et plus rapide à utiliser que le CIWA-Ar, à condition que l'utilisation du mRASS-AW n'aggrave pas les résultats, il pourrait s'agir d'une solution de rechange sécuritaire dans un environnement de SU occupé et offrir une occasion de libérer du temps pour les soins infirmiers. MéTHODES: Analyse rétrospective de séries chronologiques de la durée moyenne trimestrielle du séjour. Toutes les analyses utilisaient exclusivement la base de données des diagnostics de sortie administrative de notre hôpital. Entre le 1er avril 2012 et le 14 décembre 2014, le CIWA-Ar a été utilisé dans les unités de soins intensifs et de soins aux patients hospitalisés pour guider les décisions de dosage des benzodiazépines pour les symptômes de sevrage de l'alcool. Après ce point, CIWA-Ar a été remplacé par mRASS-AW. Les données ont été évaluées jusqu'au 31 décembre 2020. Résultat principal : durée moyenne trimestrielle du séjour. Résultats secondaires : délire, admission en unité de soins intensifs (USI), autres complications post-admission, mortalité. RéSULTATS: N = 1073 patients. Aucune association entre la durée de séjour et le changement d'échelle (changement de pente 0,3 (IC à 95 % -0,03 à 0,6), changement d'interception, 0,06 (-0,03 à 0,2). CIWA-Ar (n = 317) durée moyenne trimestrielle du séjour, 5,7 jours (95 % 4,2 à 7,1), mRASS-AW (n = 756) 5,0 jours (95 % IC 4,3 à 5,6). L'incidence du délire, de l'admission aux soins intensifs ou de la mortalité n'était pas différente. Cependant, l'incidence d'autres complications post-admission était plus élevée avec CIWA-Ar (6,6%) que mRASS-AW (3,4%) (p = 0,020). CONCLUSIONS: Il s'agissait de la première étude à comparer les résultats des patients associés à l'utilisation du mRASS-AW pour les symptômes de sevrage alcoolique en dehors des soins intensifs. Le remplacement de CIWA-Ar par mRASS-AW n'a pas aggravé la durée du séjour ou les complications. Ces résultats fournissent certaines preuves que le mRASS-AW pourrait être considéré comme une alternative au CIWA-Ar et pourrait potentiellement fournir une occasion de libérer du temps de soins infirmiers.

RESUMEN

Simultaneous allocation of service times and buffer capacities in manufacturing systems in a random environment is a NP-hard combinatorial optimisation problem. This paper presents a sophisticated simulation-based optimisation approach for the design of unreliable production lines to maximise the production rate. The proposed method allows for a global search using a Genetic Algorithm (GA), which is coupled with Finite Perturbation Analysis (FPA) as a local search technique. Traditional techniques based on perturbation analysis optimise decision variables of the same nature (e.g. service time only, buffer capacity only), whereas the proposed technique simultaneously provides an allocation of service times and buffer capacities. One of the main focuses of this paper is the investigation of the persistence or absence of the buffer and service rate allocation patterns which are among the most essential insights that come from designing production lines. The results show the superiority of the combined GA-FPA approach regarding GA and FPA in terms of solution quality and convergence behaviour. Moreover, considering instances ranging from 3 to 100 machines, our numerical experiments are in line with the literature for small instances (as similar allocation patterns are identified in our work), but important differences are highlighted for medium/large instances.

RESUMEN

Time is often an important ingredient of a healthy lifestyle. Starting from this observation, this paper studies optimal public policy concerned with promoting healthy choices taking into account both monetary and time investments in health. Individuals tend to underestimate the importance of their health while making decisions, which makes their investments too low compared to the first-best. While the decentralization of the first-best requires personalized subsidies on both time and monetary investments, this may be problematic due to informational issues. In a second-best world where individual productivities and time investments are publicly unobservable, whereas monetary investments are observable in an anonymous way, the paper considers a policy with a non-linear income tax and a linear subsidy on monetary health investments. If there are no incentive concerns, all other things equal, monetary investments complementary (substitutable) to time investments should be subsidized more (less) than those independent of time use. The addition of incentive concerns demonstrates that optimal subsidization of monetary health investments is less straightforward than one might think. Overall, the time ingredient in the production of health does play a role in the optimal policy design, affecting not only the subsidy on monetary health investments but also the income taxation.

RESUMEN

OBJECTIVE To calculate the cost of centralized dispensing of four categories of drugs （ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions） in pharmacy intravenous admixture service （PIVAS）， and provide reference for setting charging standards for relevant departments. METHODS The operating costs of PIVAS in 12 medical institutions from Shaanxi province were collected through questionnaire survey， including labor costs， medical and health material costs， fixed asset depreciation and repair costs， water and electricity costs， and management costs. The operation time allocation coefficient method and workload allocation coefficient method were comprehensively used to allocate the above costs， and the unit preparation costs of four categories of drugs were calculated. RESULTS The average annual total costs of dispensing ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions in Shaanxi province were （2 195 900.25±1 680 893.73） yuan， （746 341.59±725 839.39） yuan， （331 420.15±183 258.83） yuan， and （330 322.68±277 281.70） yuan， respectively， with labor costs accounting for the highest proportion， averaging 85.49%. The costs of dispensing a set of ordinary drugs， antibacterial drugs， and hazardous drugs were 5.89， 7.60， and 14.37 yuan， respectively； the cost of dispensing one bag of parenteral nutrition solution was 32.15 yuan （excluding the cost of disposable intravenous nutrition bags）. CONCLUSIONS The cost calculation method and data of different types of intravenous drugs obtained in this study can provide reference for relevant departments to formulate and adjust PIVAS fee standards.

RESUMEN

Background. Serious mental illness affects daily functioning, including occupational balance. Purpose. This study aims to compare occupational balance and emotional regulation between people with serious mental illness and the healthy population and to examine the relationship between occupational balance and emotional regulation. Method. A cross-sectional study was performed. Occupational balance and emotional regulation were measured using the Occupational Balance Questionnaire and the Emotional Regulation Questionnaire, respectively. A multivariate analysis (analysis of covariance) was conducted. Findings. The sample consisted of 112 individuals, divided into two groups: the serious mental illness group (n = 55); and the healthy group (n = 57). People with serious mental illness reported lower occupational balance and lower cognitive reappraisal than the healthy population. Furthermore, the higher cognitive reappraisal, the higher the occupational balance, and the higher the expressive suppression, the lower the occupational balance. Conclusion. The results provide preliminary evidence of the relationship between occupational balance and emotional regulation.

RESUMEN

This paper investigates how poor households in low-income countries trade off time investment in their children's preventive healthcare vis-à-vis labour force participation during household-level health shocks. By using the reported illness or death of any household member as the indicator for an adverse health shock, I examine its effect on the intake of Vitamin A Supplementation (VAS) by children. Using four waves of the Uganda National Panel Survey, I find that children between 12-24 months are significantly more likely to get VAS when the household is under a health shock. I argue that this effect works through an economies of scale mechanism, by which the household adult(s) utilise the released time from the labour force during the shock to access remedial care from the healthcare facility and simultaneously obtain VAS for their children during the same visit. This arguably results from the high opportunity cost of time-constrained households, which is exacerbated by a mediocre service delivery side. To distinguish the unique mechanism of the health shock in this context, the effect and channels of an income shock are also explored. By proxying a negative income shock with the household-reported incidence of flood or drought, the study cautiously hints that VAS adoption may increase among the relatively wealthy who experience a dominating substitution effect of the income shock.

RESUMEN

A fundamental question of any new relationship is, will it last? Transient relationships, recently defined by the authors, are an ideal type of social tie to explore this question: these relationships are characterized by distinguishable starting and ending temporal points, linking the question of tie longevity to relationship finite lifetime. In this study, we use mobile phone data sets from the UK and Italy to analyse the weekly allocation of time invested in maintaining transient relationships. We find that more relationships are created during weekdays, with a greater proportion of them receiving more contact during these days of the week in the long term. The smaller group of relationships that receive more phone calls during the weekend tend to remain active for more time. We uncover a sorting process by which some ties are moved from weekdays to weekends and vice versa, mostly in the first half of the relationship. This process also carries more information about the ultimate lifetime of a tie than the part of the week when the relationship started, which suggests an early evaluation period that leads to a decision on how to allocate time to different types of transient ties.

RESUMEN

Introduction: Intervention strategies that seek to improve early childhood development outcomes are often targeted at the primary caregivers of children, usually mothers. The interventions require mothers to assimilate new information and then act upon it by allocating sufficient physical resources and time to adopt and perform development promoting behaviours. However, women face many competing demands on their resources and time, returning to familiar habits and behaviours. In this study, we explore mothers' allocation of time for caregiving activities for children under the age of 2, nested within a cluster randomised controlled trial of a nutrition and care for development intervention in rural Haryana, India. Methods: We collected quantitative maternal time use data at two time points in rural Haryana, India, using a bespoke survey instrument. Data were collected from 704 mothers when their child was 12 months old, and 603 mothers when their child was 18 months old. We tested for significant differences in time spent by mothers on different activities when children are 12 months of age vs. 18 months of age between arms as well as over time, using linear regression. As these data were collected within a randomised controlled trial, we adjusted for clusters using random effects when testing for significant differences between the two time points. Results: At both time points, no statistically significant difference in maternal time use was found between arms. On average, mothers spent most of their waking time on household chores (over 6 h and 30 min) at both time points. When children were aged 12 months, approximately three and a half hours were spent on childcare activities for children under the age of 2 years. When children were 18 months old, mothers spent more time on income generating activities (30 min) than when the children were 12 years old, and on leisure (approximately 4 h and 30 min). When children were 18 months old, less time was spent on feeding/breastfeeding children (30 min less) and playing with children (15 min). However, mothers spent more time talking or reading to children at 18 months than at 12 months. Conclusion: We find that within a relatively short period of time in early childhood, maternal (or caregiver) time use can change, with time allocation being diverted away from childcare activities to others. This suggests that changing maternal time allocation in resource poor households may be quite challenging, and not allow the uptake of new and/or optimal behaviours.

RESUMEN

Faculty members are continually confronted with a multitude of activities among which they must divide their time. Prior research suggests that while men and women academics spend the same number of weekly hours working, women tend to expend more time on teaching and service relative to men while men expend more time on research relative to women. Based on cross-sectional survey data from a sample of 783 tenured or tenure-track faculty members from multiple universities, we examine gender differences in time spent in research, teaching, and university service. Regression analyses show that gender differences in time allocation continue to persist after controlling for work and family factors. More specifically, women report more time on teaching and university service than do men, while men report more time spent on research than do women. Results provide evidence that gendered differences in faculty time allocation are robust across time. Potential implications for policy are discussed.

RESUMEN

This paper analyzes the impact of widowhood on the health of mid-aged and older individuals in China using data from the China Health and Retirement Longitudinal Study (CHARLS) data. Our results show that widowhood significantly increases the risk of depression, chronic diseases, and body pain while reducing cognitive function, sleeping time, and daily activity functions. The effects on depression and daily functions are immediate, that on chronic diseases is lagged, and the effects on cognitive function and sleeping hours persist over time. We find that rural widows are particularly vulnerable to negative health outcomes due to their weaker economic positions, for whom widowhood leads to more grandchild care responsibility and corresponding workforce and social withdrawals. Moreover, rural widows' income loss is not compensated by children, either by co-residence or financial transfers, leading to reduced living standards. Overall, our findings suggest that China needs to strengthen economic security for older people, especially among rural women, in order to avoid significant negative consequences of widowhood.

RESUMEN

Allocation of attention, typically a limited capacity, is a mechanism used to filter large amounts of information and determine what stimuli are most relevant at a particular moment. In dynamic social environments as found in almost all species, including humans, multiple individuals may play a pivotal role in any given interaction where a male's attention may be divided between a rival, a current mate, and/or future potential mates. Although clearly important, the role of the social environment on attention in animals is not well understood. Here, we investigated impacts of the social environment on attention allocation using male sailfin mollies, Poecilia latipinna, which are a part of a sexual-unisexual mating system with the Amazon molly, Poecilia formosa. We asked: 1) Does the species of female influence the amount of attention a male allocates to her? And 2) Is a male's attention towards his mate influenced by different social partners? We show that males perceive a larger male as a more relevant stimulus to pay attention to compared to a smaller male, and a conspecific female (either a partner or audience) as a more relevant stimulus compared to a heterospecific female. Our results show that differential allocation of attention is dependent upon multiple components of the social environment in which an individual interacts. Understanding what qualities of rival males or potential mates provide enough meaning to males to cause a shift in attention away from a mating opportunity is essential to understanding the influence of the social environment in sexual selection.

RESUMEN

PURPOSE: Previous studies showed that unfavourable weather conditions discourage physical activity. However, it remains unclear whether unfavourable weather conditions have a differential impact on physical activity in children compared with adults. We aim to explore the differential impact of weather on time allocation to physical activity and sleep by children and their parents. METHOD: We use nationally representative data with time use indicators objectively measured on multiple occasions for >1100 Australian pairs of 12-13-year-old children and their middle-aged parents, coupled with daily meteorological data. We employ an individual fixed effects regression model to estimate the causal impact of weather. RESULTS: We find that unfavourable weather conditions, as measured by cold or hot temperatures or rain, cause children to reduce moderate- and vigorous-intensity physical activity time and increase sedentary time. However, such weather conditions have little impact on children's sleep time or the time allocation of their parents. We also find substantial differential weather impact, especially on children's time allocation, by weekdays/weekends and parental employment status, suggesting that these factors may contribute to explaining the differential weather impact that we observed. Our results additionally provide evidence of adaptation, as temperature appears to have a more pronounced impact on time allocation in colder months and colder regions. CONCLUSION: Our finding of a negative impact of unfavourable weather conditions on the time allocated to physical activity by children indicates a need to design policies to encourage them to be more physically active on days with unfavourable weather conditions and hence improve child health and wellbeing. Evidence of a more pronounced and negative impact on the time allocated to physical activity by children than their parents suggests that extreme weather conditions, including those associated with climate change, could make children vulnerable to reduced physical activity.

RESUMEN

Purpose: We examine how adolescent free time allocation-namely, screen time and outdoor time-is associated with mental health and academic performance in rural China. Methods: This paper used a large random sample of rural junior high school students in Ningxia (n = 20,375; age=13.22), with data collected from self-reported demographic questionnaires (to assess free time allocation), the Strengths and Difficulties Questionnaire (to assess mental health), and a standardized math test (to measure academic performance). We utilized a multivariate OLS regression model to examine associations between free time allocation and adolescent outcomes, controlling for individual and family characteristics. Results: Our sample's screen time and outdoor time both averaged around 1 hour. About 10% of the sample adolescents reported behavioral difficulties, while a similar percentage (11%) reported abnormal prosocial behaviors. Adolescents with higher levels of screen time (>2 hours) were 3 percentage points more likely to have higher levels of behavioral difficulties (p<0.001), indicating that excessive screen time was associated with worse mental health. Meanwhile, outdoor time was associated with better mental health, and positive correlations were observed at all levels of outdoor time (compared to no outdoor time, decreasing the likelihood of higher levels of behavioral difficulties by between 3 and 4 percentage points and of lower prosocial scores by between 6 and 8 percentage points; all p's<0.001). For academic performance, average daily screen times of up to 1 hour and 1-2 hours were both positively associated with standardized math scores (0.08 SD, p<0.001; 0.07 SD, p<0.01, respectively), whereas there were no significant associations between outdoor time and academic performance. Conclusion: Using a large sample size, this study was the first to examine the association between adolescent free time allocation with mental health and academic performance, providing initial insights into how rural Chinese adolescents can optimize their free time.

RESUMEN

Mental health concerns are on the rise among youth, contributing to a growing need for school-based mental health services. However, challenges to service provision arise due, in part, to workforce shortages, service fragmentation, and inefficient allocation of staff time. The current study describes the professional competencies and time allocation of four school-based mental health professions (i.e., school counselors, school psychologists, school social workers, and school nurses) in order to demonstrate how schools can leverage the skills of their existing staff to coordinate a comprehensive approach to support student mental health. First, we identified the core clinical competencies needed to implement the key features of comprehensive school mental health systems. Then, we crosswalked these clinical competencies with the training standards of the four professions. Finally, we conducted a systematic review of the literature to understand how these professionals' time is allocated, as well as their responsibilities related to the provision of mental health services. Results demonstrated that, although all four professions receive training in most of the core competencies needed to implement comprehensive school mental health services, their skillsets are often underutilized in day-to-day practice. Thus, we concluded that there are at least two untapped opportunities for school leaders to support student mental health-first, maximize the use of school mental health professionals through task-shifting (i.e., reassigning tasks less central to mental health service delivery to other staff), and second, implement an integrated model of school mental health services to efficiently leverage the mental health training of professionals.

RESUMEN

Background: Nutrition-sensitive agriculture (NSA) interventions may increase farm-related work for mothers, with consequences for child nutrition. The Nutrition Links (NL) intervention provided mothers with poultry, gardening inputs, technical support, and education to improve livelihoods and child nutrition outcomes in rural Ghana. Objectives: Our objective was to compare time allocated to child care by a cross-section of mothers in the intervention group of the NL intervention with the control group (NCT01985243). Methods: A cross-section of NL mother-child pairs was included in a time allocation substudy [intervention (NL-I) n = 74 and control (NL-C) n = 69]. In-home observations of the mother-child pair were conducted for 1 min, every 5 min, for 6 h. Observations were categorized into 4 nonoverlapping binary variables as follows: 1) maternal direct care, 2) maternal supervisory care, 3) allocare, and 4) no direct supervision. Allocare was defined as care by another person in the presence or absence of the mother. Any care was defined as the observation of maternal direct care, maternal supervisory care, or allocare. Generalized linear mixed models with binomial data distribution were used to compare the child care categories by group, adjusting for known covariates. Results: Maternal direct care (OR = 1.07; 95% CI: 0.89, 1.28) and any care (OR = 1.56; 95% CI: 0.91, 2.67) did not differ by intervention group. However, there was a higher odds of allocare (OR = 1.36; 95% CI: 1.04, 1.79) in NL-I than in NL-C women. Conclusions: Maternal participation in an NSA intervention was not associated with a decrease in time spent directly on child care but was associated with an increase in care from other household and community members.The clinicaltrials.gov number provided is for the main NL intervention and not this current substudy.

RESUMEN

Understanding how coupled adults arrange food-related labor in relation to their daily time allocation is of great importance because different arrangements may have implications for diet-related health and gender equity. Studies from the time-use perspective argue that daily activities such as work, caregiving, and non-food-related housework can potentially compete for time with foodwork. However, studies in this regard are mostly centered on individual-level analyses. They fail to consider cohabiting partners' time spent on foodwork and non-food-related activities, a factor that could be helpful in explaining how coupled partners decide to allocate time to food activities. Using 108 daily time-use logs from seventeen opposite-gender couples living in Toronto, Canada, this paper examines how male and female partners' time spent on non-food-related activities impact the total amount of time spent on foodwork by coupled adults and the difference in time spent on foodwork between coupled women and men. Results show that both male and female partners took a higher portion of foodwork when their partner worked longer. When men worked for additional time, the couple-level duration of foodwork decreased. Without a significant impact on the gender difference in foodwork duration, women's increased caregiving duration was associated with a reduction of total time spent on foodwork by couples. An increase in caregiving and non-food-related chores by men was associated with an increased difference in duration of foodwork between women and men, which helped secure a constant total amount of foodwork at the couple level. These behavioral variations between men and women demonstrate the gender differences in one's responsiveness to the change of partners' non-food-related tasks. The associations found among non-food-related activities and foodwork are suggestive of a need to account for partners' time allocation when studying the time-use dynamics of foodwork and other daily activities.
