Structure and Implementation of Novel Task Rules: A Cross-Sectional Developmental Study.

ABSTRACT: Rule-based performance improves remarkably throughout childhood. The present study examined how children and adolescents structured tasks and implemented rules when novel task instructions were presented in a child-friendly version of a novel instruction-learning paradigm. Each miniblock started with the presentation of new stimulus-response mappings for a go task. Before this mapping could be implemented, subjects had to make responses in order to advance through screens during a preparatory (" next") phase. Children (4-11 years old) and late adolescents (17-19 years old) responded more slowly during the next phase when the next response was incompatible with the instructed stimulus-response mapping. This instruction-based interference effect was more pronounced in young children than in older children. We argue that these findings are most consistent with age-related differences in rule structuring. We discuss the implications of our findings for theories of rule-based performance, instruction-based learning, and development.

Project description:BACKGROUND:There has been an increase in children growing up in non-traditional families, such as single-parent and blended families. Children from such families have a higher prevalence of obesity and poorer health outcomes, but research on the relationship with obesogenic behaviours is limited. OBJECTIVES:Therefore, the aim of this study was to investigate whether there are associations between family structures and obesogenic behaviours and related family rules in European children and adolescents. METHODS:The sample included 7664 children (mean age?±?SD: 10.9?±?2.9) from 4923 families who were participants of the multi-centre I.Family study (2013/2014) conducted in 8 European countries. Family structure was assessed by a detailed interview on kinship and household. Obesogenic behaviours (screen time, sleep duration, consumption of sugar-sweetened beverages (SSBs)) and family rules (rules for computer and television, bedtime routine, availability of SSBs during meals) were determined by standardized questionnaires. Multilevel mixed-effects linear and logistic regression models were used to model the associations of family structure with obesogenic behaviours and family rules. Sex, age, parental education level, number of children and adults in the household and BMI z-score were covariates in the models. Two-parent biological families were set as the reference category. RESULTS:Children from single-parent families were less likely to have family rules regarding screen time (OR: 0.62, 95% CI: 0.40-0.94, p?=?0.026) with higher reported hours of screen time per week (??=?2.70?h/week, 95% CI: 1.39-4.00, p?<?0.001). The frequency of weekly SSB consumption differed by family structure in a sex-specific manner: girls from single-parent (??=?3.19 frequency/week, 95% CI: 0.91-5.47, p?=?0.006) and boys from blended/adoptive families (??=?3.01 frequency/week, 95% CI: 0.99-5.03, p?=?0.004) consumed more SSBs. Sleep duration, bedtime routines and availability of SSBs during meals did not differ between children from these family structures. Parental education did not modify any of these associations. CONCLUSIONS:Parents in non-traditional family structures appear to experience more difficulties in restricting screen time and the intake of SSBs in their children than parents in traditional two-parent family structures. Our findings therefore suggest that additional support and effective strategies for parents in non-traditional families may help to reduce obesogenic behaviours in children from such family types.

Project description:BackgroundTelemedicine has been used widely in China and has benefited a large number of patients, but little is known about the overall development of telemedicine.ObjectiveThe aim of this study was to perform a national survey to identify the overall implementation and application of telemedicine in Chinese tertiary hospitals and provide a scientific basis for the successful expansion of telemedicine in the future.MethodsThe method of probability proportionate to size sampling was adopted to collect data from 161 tertiary hospitals in 29 provinces, autonomous regions, and municipalities. Charts and statistical tests were applied to compare the development of telemedicine, including management, network, data storage, software and hardware equipment, and application of telemedicine. Ordinal logistic regression was used to analyze the relationship between these factors and telemedicine service effect.ResultsApproximately 93.8% (151/161) of the tertiary hospitals carried out telemedicine services in business-to-business mode. The most widely used type of telemedicine network was the virtual private network with a usage rate of 55.3% (89/161). Only a few tertiary hospitals did not establish data security and cybersecurity measures. Of the 161 hospitals that took part in the survey, 100 (62.1%) conducted remote videoconferencing supported by hardware instead of software. The top 5 telemedicine services implemented in the hospitals were teleconsultation, remote education, telediagnosis of medical images, tele-electrocardiography, and telepathology, with coverage rates of 86.3% (139/161), 57.1% (92/161), 49.7% (80/161), 37.9% (61/161), and 33.5% (54/161), respectively. The average annual service volume of teleconsultation reached 714 cases per hospital. Teleconsultation and telediagnosis were the core charging services. Multivariate analysis indicated that the adoption of direct-to-consumer mode (P=.003), support from scientific research funds (P=.01), charging for services (P<.001), number of medical professionals (P=.04), network type (P=.02), sharing data with other hospitals (P=.04), and expertise level (P=.03) were related to the effect of teleconsultation. Direct-to-consumer mode (P=.01), research funding (P=.01), charging for services (P=.01), establishment of professional management departments (P=.04), and 15 or more instances of remote education every month (P=.01) were found to significantly influence the effect of remote education.ConclusionsA variety of telemedicine services have been implemented in tertiary hospitals in China with a promising prospect, but the sustainability and further standardization of telemedicine in China are still far from accomplished.

Project description:BackgroundThe literature on perceptual differences between managers and staff regarding social dynamic factors (e.g., leadership, climate) in nursing settings is sparse. Addressing this gap in knowledge is critical for informing implementation efforts and improving patient and organizational outcomes. The purpose of this study was to test the perceptual differences regarding implementation leadership and implementation climate between nursing staff and their managers.MethodsThis study was a secondary analysis of cross-sectional survey data collected in 2016-2017. The setting included 22 adult medical-surgical units nested in 7 acute care hospitals in the Eastern and Midwestern United States. Participants were registered nurses (N = 261) and nurse managers (N = 22) who completed an electronic survey consisting of the Implementation Leadership Scale (ILS), the Implementation Climate Scale (ICS), and demographic items. Differences in perception were analyzed at the unit level using structural equation modeling to develop latent difference score models (LDS). We assessed associations of the LDSs with manager ILS and ICS scores, years of nursing experience, and years of experience working on the current unit. The association of ILS LDS with the observed nursing staff ICS scores was also analyzed.ResultsHigher manager scores on the ILS and ICS were associated with greater perceptual differences in implementation leadership and implementation climate. Greater years of experience as a nurse were associated with greater perceptual differences in ILS and ICS scores. Greater tenure on the unit was associated with smaller differences on the ILS knowledge domain. Greater perceptual differences regarding implementation leadership were associated with worse staff ratings of implementation climate.ConclusionsAlthough this study observed significant relationships among manager ILS and ICS scores, staff-manager perceptual differences, and staff ratings of implementation climate in nursing settings, it is still unclear why perceptual differences in implementation leadership and climate exist and how to address them. Future studies are warranted to test the effect of perceptual differences on implementation and patient outcomes.
