Exploring the Relationship between Attention-Deficit/Hyperactivity Disorder and Creativity

Attention-Deficit/Hyperactivity Disorder (ADHD) is an important topic to study because of its prevalence, impact, and a multitude of unknown interactions of the disorder with creativity. Creativity is a cognitive process defined by lessened cognitive control and lower inhibitions in the prefrontal cortex (Chrysikou, 2018), which are characteristics of ADHD (APA, 2017; Brunkhorst-Kanaan et al., 2021; Kirov & Brand, 2014; Laugesen et al., 2017; Moen et al., 2014; Staikova et al., 2013) This study explored how ADHD is connected with three sub-variables of creativity: divergent thinking, uniqueness of generated ideas, and flow of ideas. Connections were explored via a survey of ADHD symptoms and both subjective and objective measures of creativity in a sample of 252 college students. I hypothesized that ADHD would be associated with higher divergent thinking, higher uniqueness of ideas, and lower flow of ideas. Based on the results, ADHD was associated with higher divergent thinking and higher flow of ideas, and there was no relationship between ADHD and uniqueness of ideas. The direction and intensity of the relationships found may be impacted by factors within this study, and some findings are consistent with the field of ADHD research while other findings are not. In the future, creativity as a variable stands to need an operationalized, valid, agreed-upon measure created to accurately assess levels of creativity. Synopsized, while there are conflicting findings on the direction and intensity of the relationship between creativity and ADHD, this study found evidence that a relationship is present for at least some aspects of creativity

The potential health benefits of seaweed and seaweed extract

Edible seaweeds have historically been consumed by coastal populations across the globe. Today, seaweed is still part of the habitual diet in many Asian countries. Seaweed consumption also appears to be growing in popularity in Western cultures, due both to the influx of Asian cuisine as well as notional health benefits associated with consumption. Isolates of seaweeds (particularly viscous polysaccharides) are used in an increasing number of food applications in order to improve product acceptability and extend shelf-life. Epidemiological evidence suggests regular seaweed consumption may protect against a range of diseases of modernity. The addition of seaweed and seaweed isolates to foods has already shown potential to enhance satiety and reduce the postprandial absorption rates of glucose and lipids in acute human feeding studies, highlighting their potential use in the development of anti-obesity foods. As seaweeds and seaweed isolates have the potential to both benefit health and improve food acceptability, seaweeds and seaweed isolates offer exciting potential as ingredients in the development of new food products. This review will outline the evidence from human and experimental studies that suggests consumption of seaweeds and seaweed isolates may impact on health (both positively and negatively). Finally, this review will highlight current gaps in knowledge in this area and what future strategies should be adopted for maximising seaweed's potential food uses

Ascophyllum nodosum enriched bread reduces subsequent energy intake with no effect on post-prandial glucose and cholesterol in healthy, overweight males. A pilot study.

The consumption of seaweed isolates (such as alginate) has been shown to successfully reduce energy intake and modulate glycaemic and cholesterolaemic responses. To date, the effect of adding whole seaweed to bread has not been widely investigated. This study aims to investigate the acceptability of Ascophyllum nodosum enriched bread, and measure its effect on energy intake and nutrient absorption in overweight, healthy males. Results from the acceptability study, (79 untrained sensory panellists) indicated that it is acceptable to incorporate seaweed (Ascophyllum nodosum) into a staple food such as bread when up to 20g are added to a 400g wholemeal loaf. A single blind cross over trial (n=12 males, aged 40.1±12.5 years; BMI 30.8±4.4 kg/m2) was used to compare energy intake and nutrient uptake after a breakfast meal using the enriched bread against the control bread. Consumption of the enriched bread led to a significant reduction (16.4%) in energy intake at a test meal 4 hours after breakfast. Differences between treatment arms for area under the curve, peak values, and time of peak for blood glucose and cholesterol were not significant. Further investigation of potential mechanisms of action is warranted

Dietary seaweed and human health

Seaweed as an ingredient is growing in popularity largely due to its perceived health-giving properties supported by findings from epidemiological studies. Increased seaweed consumption has been linked to reduced risk of various diseases however there is a paucity of evidence for health benefits derived from robust randomised controlled trials (RCT). Emerging data from short-term RCT involving seaweed isolates are promising. Further investigation of seaweed as a wholefood ingredient is warranted. This review aims to highlight the food uses and potential health benefits of seaweeds

Investigating the Effects of Climatic Change and Fire Dynamics on Peatland Carbon Accumulation in Coastal Labrador, Canada

High-latitude peatlands store a large stock of carbon in accumulated belowground biomass, estimated at 500 ± 100 Gt C (Yu 2012). For comparison, the atmospheric C pool is estimated at about 775 Gt (IPCC 2007) making the peatland carbon pool a potentially significant player in the global carbon cycle. Peatland carbon storage is controlled by a balance between plant productivity and decomposition, with plant matter produced during the summer months accumulating from year to year rather than fully decomposing. Peatlands are sensitive to changes in climatic regime and have the potential to shift from a net sink of atmospheric C to a net source of C with future disturbance by climate warming (Yu 2012).There are two major predictions as to how climate change could affect peatland C accumulation. Warmer temperatures could cause faster decomposition of plant biomass and lead to C release to the atmosphere and a positive feedback effect on climate change (Schuur et al. 2008). If this is the case, current warming trends suggest that peatlands could release up to 100 Gt C to the atmosphere by the year 2100 (Davidson and Janssens 2006). Alternatively, warmer summer temperatures and a longer growing season could lead to faster peat production and therefore CO2 drawdown from the atmosphere, somewhat mitigating the effects of climate change (Schuur et al. 2008). A detailed study of past C accumulation rates over a known historical warm period gives insight into how peatlands may respond to future climate warming. This project focuses on C accumulation in peatlands in Labrador, Canada, over the past 8,000 years. Because Canadian peatlands store approximately 150 Gt C, approximately 1/3 of the global peatland carbon pool, it is important to understand how the dynamics of these peatlands could be affected by present and future climate warming (Tarnocai 2006). However, the majority of research has focused on central Canada, leaving significant knowledge gaps surrounding coastal Eastern Canada (vanBellen et al. 2012). Particular emphasis in this study was given to the Holocene Thermal Maximum (HTM) which occurred from 4-6 thousand years ago in Labrador, when summer temperatures were 0.5 – 1°C warmer than at present (Kerwin et al. 2004). This study also attempts to determine the effect of fires on rates of C storage in these peatlands. Lightning-ignited peat fires have the potential to consume stored biomass and release significant CO2 to the atmosphere (Tarnocai 2006). Six peat cores (out of a total of 14 collected in Labrador in 2013) were used for this study. Throughout the following year, calibrated radiocarbon dates, bulk density, and percent carbon were used to calculate carbon accumulation rates. This summer, areal charcoal concentration (a measure of macroscopic charcoal used as a proxy for fire severity) was used to determine the influence of fires in this region. From 8,000 years ago to the present, rates of C accumulation averaged 23.1 ± 6.7 gC m-2 yr-1. Accumulation rates were highest during the HTM, averaging 29.6 ± 2.4 g C m-2 yr-1. Samples containing macroscopic charcoal had an average concentration of 0.62 mm2 cm-3 with a maximum concentration found of 3.51 mm2 cm-3. These consistently low charcoal concentrations indicate that fire was neither common nor severe in Labrador peatlands. While Kuhry (1994) and Payette et al. (2012) found that fires in Canada occurred twice as frequently during the HTM than at present, no trends in fire severity were found in these cores, and there was no evidence that fires had a significant influence on C accumulation. Therefore, the C accumulation trend we see in Labrador is not controlled by fire and is likely either a direct result of temperature variation or of vegetational and hydrological shifts caused by changes in climate. This work supports a growing body of evidence from high latitude peatlands suggesting that future warming conditions could lead to increased soil C sequestration

Weight loss is coupled with improvements to affective state in obese participants engaged in behavior change therapy based on incremental, self-selected “Small Changes”

The aim of this study was to investigate the effects of a group behavior change intervention involving self-selected, contextualized, and mediated goal setting on anthropometric, affective, and dietary markers of health. It was hypothesized that the intervention would elicit changes consistent with accepted health recommendations for obese individuals. A rolling program of 12-week “Small Changes” interventions during 24 months recruited 71 participants; each program accommodated 10 to 13 adults (body mass index [BMI] ≥30 kg/m2). Fifty-eight participants completed Small Changes. Repeated measures were made at baseline, 6 and 12 weeks. Anthropometric measures included height and weight (to calculate BMI), body composition, waist circumference, and blood pressure. Affective state was monitored using relevant validated questionnaires. Dietary assessment used 3-day household measures food diaries with Schofield equations to monitor underreporting. Relevant blood measures were recorded throughout. Across the measurement period, Small Changes elicited a significant reduction in body weight (baseline, 102.95 ± 15.47 vs 12 weeks 100.09 ± 16.01 kg, P < .0005), coupled with associated significant improvements in BMI, body fat percentage, and waist circumference measures. There were additional significant positive changes in measures of affective state including general well-being (baseline, 58.92 ± 21.22 vs 12 weeks 78.04 ± 14.60, P < .0005) and total mood disturbance (baseline, 31.19 ± 34.03 vs 12 weeks 2.67 ± 24.96, P < .0005). Dietary changes that occurred were largely consistent with evidenced-based recommendations for weight management and included significant reductions in total energy intake and in fat and saturated fat as a proportion of energy. The Small Changes approach can elicit a range of health-orientated benefits for obese participants, and although further work is needed to ascertain the longevity of such effects, the outcomes from Small Changes are likely to help inform health professionals when framing the future of weight management. Long-term follow-up of Small Changes is warranted

The Writing Attitude Scale for Teachers (WAST)

This study examines the psychometric properties of the Writing Attitude Scale for Teachers (WAST) using scores of preservice teachers to gather evidence of content, internal structure, response processes, reliability/precision, and correlations with external variables. Four contending models were compared using CFA, but the unidimensional model was championed. The WAST was further refined using IRT to 10-items and shown to have high precision across most of the latent continuum. The WAST was shown to have incremental evidence relative to the Writing Apprehension Test when predicting attitudes towards attending a professional development workshop on writing instruction and time devoted to writing instruction

Ethnography in Congregations

Ethnography is increasingly used in research conducted in congregations. Ethnography can provide rich description and is able to navigate between the stories of congregational members and the story observed by the researcher. Quality ethnography in congregations requires attention to ethics, navigating insider/outsider dynamics, and research aims
