Self Perceptions

As drowning is a leading cause of unintentional injury/death in children worldwide, perceptions of their actual aquatic skills are of critical importance. Children’s self-perceptions may influence the risks they take, and parental perceptions may influence the degree of supervision deemed to be necessary for children in and around water. Accordingly, we examined the differences between young children’s actual, self-perceived and parent-perceived aquatic skills. Using a three-way repeated measures ANCOVA, we analyzed data from 134 child-parent dyads (56.0% boys; M age = 7.1, SD = 1.1 years; and 71.6% mothers). We measured self and parental perceptions of the child’s aquatic skills with the ‘Pictorial Scale of Perceived Water Competence’ (PSPWC), and we applied the exact same 17 test items of the PSPWC to assess the child’s actual aquatic skill level in the water. Controlling for years of swimming school experience, within-subject differences between the total scores on the ‘Actual Aquatic Skills Test’ (AAST) and both the child- and parent-completed PSPWC indicated lower than actual estimates of the children’s aquatic skill level. The degree of disagreement against the AAST was more pronounced in parents than in 6-7 year-old children but was similar between parents and 8-9 year-old children, with these patterns being evident regardless of the children’s sex. Our study contributes to an ongoing validation of the PSPWC and represents a key advance in assessing and comparing children’s actual and perceived aquatic skill competence, using perfectly aligned instruments. Future research and practice might explore children’s actual aquatic skills in different contexts (e.g., open water), include perspectives of non-parent caregivers and assess perceived and actual water competence across development.

Abstract. Low precision of the inferences of data analyzed with univariate or multivariate models of the Analysis of Variance (ANOVA) in repeated-measures design is associated to the absence of normality distribution of data, nonspherical covariance structures and free variation of the variance and covariance, the lack of knowledge of the error structure underlying the data, and the wrong choice of covariance structure from different selectors. In this study, levels of statistical power presented the Modified Brown Forsythe (MBF) and two procedures with the Mixed-Model Approaches (the Akaike’s Criterion, the Correctly Identified Model [CIM]) are compared. The data were analyzed using Monte Carlo simulation method with the statistical package SAS 9.2, a split-plot design, and considering six manipulated variables. The results show that the procedures exhibit high statistical power levels for within and interactional effects, and moderate and low levels for the between-groups effects under the different conditions analyzed. For the latter, only the Modified Brown Forsythe shows high level of power mainly for groups with 30 cases and Unstructured (UN) and Autoregressive Heterogeneity (ARH) matrices. For this reason, we recommend using this procedure since it exhibits higher levels of power for all effects and does not require a matrix type that underlies the structure of the data. Future research needs to be done in order to compare the power with corrected selectors using single-level and multilevel designs for fixed and random effects.

The Relationship

Contracts are a formal mode of governing interorganizational relationships. They specify the terms and conditions of the agreement between two parties, interpret and adapt the relevant legal and industrial norms, serve as framing devices, and establish the rules and norms underpinning the relationship. The objective of this chapter is to synthesize the extant literature on interorganizational contracting to guide future research and practice. This chapter focuses on the three phases of contracting: (1) designing the contracting portfolio; (2) negotiating initial contracts; and (3) managing the relationship using contracts. The chapter explores the key decisions in each phase and the criteria involved in making these decisions. In doing so, it draws on existing research and theoretical frameworks that have contributed to the development of the contracting literature. The chapter also identifies some important and interesting directions for future contracting research and offers suggestions regarding how selected theoretical lenses might guide these endeavors. The principal conclusion is that while the existing research has primarily focused on the structural issues guiding contracting design, a more processual, social, and behavioral focus is required in future developments of the contracting literature.

Professional development (PD) provides an opportunity to promote the psychological, social, and physical health tools teachers require to maintain teacher wellbeing. Despite their potential, little is known about PD programs targeting the health and wellbeing of Australian teachers. This study aimed to summarize the characteristics of Australian PD programs targeted at teacher wellbeing, identify gaps in existing PD and make recommendations for future research and practice. Three search strategies, (1) search engine results, (2) a manual search of known Australian education websites, and (3) requests for information from Australian education organizations, were combined to ensure a comprehensive inventory of PD programs was compiled. This study found 63 PD programs promoting health and wellbeing that currently exist for Australian teachers. Of these, only three provided evidence of their evaluation indicating programs are advertised and implemented without evidence of their effectiveness. Future PD should be evaluated with findings of the evaluations reported publicly so evidence-based programs promoting teacher’s health and wellbeing can be recommended and implemented.

Abstract Background The migration patterns of land birds can generally be divided into those species that migrate principally during the day and those that migrate during the night. Some species may show individual plasticity in the use of day or night flight, particularly when crossing large, open-water or desert barriers. However, individual plasticity in circadian patterns of migratory flights in diurnally migrating songbirds has never been investigated. Methods We used high precision GPS tracking of a diurnal, migratory swallow, the purple martin (Progne subis), to determine whether individuals were flexible in their spring migration strategies to include some night flight, particularly at barrier crossing. Results Most (91%) of individuals made large (sometimes > 1000 km), open-water crossings of the Caribbean Sea and the Gulf of Mexico that included the use of night flight. 32% of all water crossings were initiated at night, demonstrating that night flight is not only used to complete large crossings but may confer other advantages for diurnal birds. Birds were not more likely to initiate crossings with supportive winds, however crossings were more likely when they reduced travel distances. Our results are consistent with diurnal birds using night flight to help achieve time- and energy-savings through ‘short cuts’ at barrier crossings, at times and locations when foraging opportunities are not available. Conclusions Overall, our results demonstrate the use of nocturnal flight and a high degree of individual plasticity in migration strategies on a circadian scale in a species generally considered to be a diurnal migrant. Nocturnal flights at barrier crossing may provide time and energy savings where foraging opportunities are low in an otherwise diurnal strategy. Future research should target how diel foraging and refueling strategies support nocturnal flights and barrier crossing in this and other diurnal species.

Research on the relationship between automation services and tourism has been rapidly growing in recent years and has led to a new service landscape where the role of robots is gaining both practical and research attention. This paper builds on previous reviews and undertakes a comprehensive analysis of the research literature to discuss opportunities and challenges presented by the use of service robots in hospitality and tourism. Management and ethical issues are identified and it is noted that practical and ethical issues (roboethics) continue to lack attention. Going forward, new directions are urgently needed to inform future research and practice. Legal and ethical issues must be proactively addressed, and new research paradigms developed to explore the posthumanist and transhumanist transitions that await. In addition, closer attention to the potential of “co-creation” for addressing innovations in enhanced service experiences in hospitality and tourism is merited. Among others, responsibility, inclusiveness and collaborative human-robot design and implementation emerge as important principles to guide future research and practice in this area.

It is a common assumption that children with disabilities are more likely to experience victimization than their peers without disabilities. However, there is a paucity of robust research supporting this assumption in the current literature. In response to this need, we conducted a logistic regression analysis using a national dataset of responses from 26,572 parents/caregivers to children with and without disabilities across all 50 states, plus the District of Columbia. The purpose of our study was to acquire a greater understanding of the odds of victimization among children with and without intellectual disability (ID), while controlling for several child and parent/adult demographic correlates. Most notably, our study revealed that children with ID have 2.84 times greater odds of experiencing victimization than children without disabilities, after adjusting for the other predictors in the model. Implications for future research and practice are discussed.

The purpose of this study was to examine the effects of a tactical games model instructional plan on game-play volleyball performances of elementary school students, taking into account their skill level. In total, 39 fourth-grade students (average age: 8.9 years) participated in a 13-week unit, in which each lesson exaggerated the use of small-sided games. In-game performances were assessed via the Team Sport Assessment Procedure, while students played a 10-minute modified game (four versus four). Data were collected pre- and post-intervention, and after the summer vacation (retention test). A 2 (skill level) × 3 (time) analysis of variance with repeated measures was used to compare students’ performance, and the relevant effects were interpreted mainly by means of confidence intervals and effect size measures. At the end of the instructional period, all participants had an overall moderate to large improvement, and this global improvement seems to have remained at least until the end of the summer vacation. Lower-skilled students attained a larger and more established improvement than high-skilled students did. However, some detrimental effects on in-game students’ performance existed at the end of the instructional period. Therefore, teachers have to take into account students’ skill levels when designing their lessons because, if small-sided games are adequately considered and managed, students’ learning processes can be enhanced. Furthermore, the students should be assigned appropriate learning activities to avoid summer learning loss in physical education.

Acute care practice settings are stressful. Nurse leaders face stressful demands of numerous competing priorities. Some nurse leaders experience unmanageable stress, but success requires self-care. This article presents a repeated measures intervention design study using mixed methods to investigate a self-care simple meditation practice for nurse leaders. Themes and subthemes emerged in association with the three data collection points: at baseline (pretest), after 6 weeks, and after 12 weeks (posttest) from introduction of the self-care simple meditation practice. An analysis of variance yielded a statistically significant drop in perceived stress at 6 weeks and again at 12 weeks. Conducting future research is merited.

Digital technologies are increasingly used in health-care delivery and are being introduced into work to prevent unintentional injury, violence, and suicide to reduce mortality. To understand the potential of digital health interventions (DHIs) to prevent and reduce these problems, we conduct a meta-analysis and provide an overview of their effectiveness and characteristics related to the effects. We searched electronic databases and reference lists of relevant reviews to identify randomized controlled trials (RCTs) published in or before March 2020 evaluating DHIs on injury, violence, or suicide reduction. Based on the 34 RCT studies included in the meta-analysis, the overall random effect size was 0.21, and the effect sizes for reducing suicidal ideation, interpersonal violence, and unintentional injury were 0.17, 0.24, and 0.31, respectively, which can be regarded as comparable to the effect sizes of traditional face-to-face interventions. However, there was considerable heterogeneity between the studies. In conclusion, DHIs have great potential to reduce unintentional injury, violence, and suicide. Future research should explore DHIs’ successful components to facilitate future implementation and wider access.
