The Impact of Natural Playscapes on Toddler Play

A distinct lack of data related to the impact of natural environments on children birth to age 3 was identified by a thematic review of the existing literature. With this in mind, the researcher designed a limited scope quantitative study to explore the potential for extending the existing body of research to include this younger age. The study used a time sampling method to code behaviors that occurred in videos collected of children from 12 to 35 month who were playing on the playground at their childcare facility. The playscapes were classified as naturalistic or manufactured. The data was then analyzed using independent t-tests to look for statistically significant variations to the frequent that children engaged in various social and play based behaviors. The results of the study were minimal but were significant enough to support the value of further research involving children birth to three

Across the Great Wall: The Politics and Economics of Transmission in Disney's Mulan

Film adaptations of folktales have been examined from many angles, but not as a form of folktale transmission. In the era of globalization, these films play a large role, especially in transmitting folklore between cultures. As an example of this, I examine Disney's Mulan, which brought a folktale well-known in China to an American and global audience unfamiliar with the source material. In order to understand the process and implications of Mulan's transmission, I employ World Systems Theory and the work of Arjun Appadurai. This illuminates how the folktale was appropriated, the exchanges the film inspired, and the impact the film has had.Master of Art

Children’s true and false memories of valenced material

There has been a rise in anxiety amongst typically developing children in recent years. Existing research has suggested a link between the increase of television viewing, and the increase in childhood anxiety. This thesis confirms the plausibility of this hypothesis; a meta-analysis found a small but consistent effect of viewing “scary” television on children’s internalizing responses. Existing cognitive models of emotional processing in anxious individuals identify attention, interpretation, and memory preferences towards emotionally negative materials as potential mediators. Whilst attention and interpretation preferences have been well evidenced, the link between anxiety and negativity preferences in memory is more tenuous, particularly in typically developing children. A positive-negative asymmetry in memory is well established in adults; however, the extent to which children process and remember positive, negative and neutral stimuli differentially is relatively unexplored. The Deese–Roediger–McDermott (DRM) paradigm has been utilised to allow analysis of memory accuracy and response bias. There were several key findings within this thesis. In line with previous research, a preference away from negatively valenced material was found when simple word list stimuli was used. When narratives were used as a richer source of material, memory performance was greater for negatively, than positively valenced stimuli. However, when two sources differing on richness of information (visual vs narrative stimuli), and valence (positive vs negative) were presented simultaneously, the modality effect became dominant; the richer source of material was discriminated with higher accuracy, regardless of valence. When this effect was followed up, no evidence of a mood interaction within emotional memory was found. Semantic elaboration was explored as a potential mechanism behind valence effects in memory. However, no positive findings were identified. Age, gender and trait anxiety did not reliably moderate valence effects on memory. This thesis adds to the small body of knowledge focusing on children’s emotional memory, particularly by including response bias analyses. It highlights the complex nature of emotional processing in children and some of the factors contributing to accuracy. Further research should explore in greater depth how valence effects differ for various types of stimuli, and under which circumstances these effects can be overridden. Mechanisms behind these valence effects are also yet to be unpicked

Basic income experiments in OECD countries:A rapid evidence review

Since 2015, the idea of a universal basic income (UBI) has inspired an increasing number ofexperiments in OECD countries. In this report, we provide a rapid evidence review of thecharacteristics, indicators and outcomes of these basic income experiments in order to informpolicymakers about gaps in knowledge and to make suggestions for future experimental design.We found 38 experiments across Europe, North America and Asia that met inclusion criteria.Most experiments involve cash benefits targeted at a relatively small number of low-incomehouseholds for a period of roughly two years dispersed across a relatively large area. We consider thatthis makes a sound case for the development of more heterogenous target groups, a longer time periodand a greater examination of community effects. We also provide some suggestions for more policy-and political-oriented goals, which we argue are an oft-ignored elements of these experiments inpolicymaking and research

Intra-dance variation among waggle runs and the design of efficient protocols for honey bee dance decoding

Noise is universal in information transfer. In animal communication, this presents a challenge not only for intended signal receivers, but also to biologists studying the system. In honey bees, a forager communicates to nestmates the location of an important resource via the waggle dance. This vibrational signal is composed of repeating units (waggle runs) that are then averaged by nestmates to derive a single vector. Manual dance decoding is a powerful tool for studying bee foraging ecology, although the process is time-consuming: a forager may repeat the waggle run 1- >100 times within a dance. It is impractical to decode all of these to obtain the vector; however, intra-dance waggle runs vary, so it is important to decode enough to obtain a good average. Here we examine the variation among waggle runs made by foraging bees to devise a method of dance decoding. The first and last waggle runs within a dance are significantly more variable than the middle run. There was no trend in variation for the middle waggle runs. We recommend that any four consecutive waggle runs, not including the first and last runs, may be decoded, and we show that this methodology is suitable by demonstrating the goodness-of-fit between the decoded vectors from our subsamples with the vectors from the entire dances

Does the choice of neighbourhood supermarket access measure influence associations with individual-level fruit and vegetable consumption? A case study from Glasgow

BackgroundPrevious studies have provided mixed evidence with regards to associations between food store access and dietary outcomes. This study examines the most commonly applied measures of locational access to assess whether associations between supermarket access and fruit and vegetable consumption are affected by the choice of access measure and scale.MethodSupermarket location data from Glasgow, UK (n = 119), and fruit and vegetable intake data from the \u27Health and Well-Being\u27 Survey (n = 1041) were used to compare various measures of locational access. These exposure variables included proximity estimates (with different points-of-origin used to vary levels of aggregation) and density measures using three approaches (Euclidean and road network buffers and Kernel density estimation) at distances ranging from 0.4 km to 5 km. Further analysis was conducted to assess the impact of using smaller buffer sizes for individuals who did not own a car. Associations between these multiple access measures and fruit and vegetable consumption were estimated using linear regression models.ResultsLevels of spatial aggregation did not impact on the proximity estimates. Counts of supermarkets within Euclidean buffers were associated with fruit and vegetable consumption at 1 km, 2 km and 3 km, and for our road network buffers at 2 km, 3 km, and 4 km. Kernel density estimates provided the strongest associations and were significant at a distance of 2 km, 3 km, 4 km and 5 km. Presence of a supermarket within 0.4 km of road network distance from where people lived was positively associated with fruit consumption amongst those without a car (coef. 0.657; s.e. 0.247; p0.008).ConclusionsThe associations between locational access to supermarkets and individual-level dietary behaviour are sensitive to the method by which the food environment variable is captured. Care needs to be taken to ensure robust and conceptually appropriate measures of access are used and these should be grounded in a clear a priori reasoning

Adverse effects of pegaspargase in pediatric patients receiving doses greater than 3,750 IU

BackgroundIncreased toxicities have been identified with higher doses of pegaspargase (PEG‐ASP) in adults. This has led to routine use of a dose cap of 3,750 IU for adult acute lymphoblastic leukemia (ALL) patients in most institutions. In pediatric ALL patients, PEG‐ASP is not capped. There is concern at our institution that larger doses may result in increased rates of adverse effects and that increased monitoring may be warranted in pediatric patients receiving doses greater than 3,750 IU. The objective of this study is to quantify the difference in the rates of PEG‐ASP‐associated adverse events between pediatric patients who received doses greater than 3,750 IU and less than or equal to 3,750 IU.MethodsRetrospective chart review of patients 1–21 years old with pre‐B‐cell ALL who received PEG‐ASP between 2007 and 2014 at an academic medical center.ResultsOf 183 patients included in the analysis, 24 received PEG‐ASP doses higher than 3,750 IU and 159 received doses less than or equal to 3,750 IU. The incidence of venous thromboembolism (VTE) was significantly higher for patients in the group that received more than 3,750 IU compared with those who received 3,750 IU or less (20.8 vs. 1.89%, respectively; P = 0.0011). The incidence of pancreatitis (P = 0.0306) and hyperglycemia (P = 0.0089) were also higher in the group that received more than 3,750 IU.ConclusionsPEG‐ASP doses higher than 3,750 IU are associated with higher rates of VTE, pancreatitis, and hyperglycemia in pediatric patients with pre‐B‐cell ALL. Patients receiving more than 3,750 IU should have increased monitoring, and larger, multicenter trials are needed to determine if monitoring, VTE prophylaxis, and potential dose capping recommendations should be added to clinical trial protocols.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/138220/1/pbc26555_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/138220/2/pbc26555.pd
