How Framing Climate Change Influences Citizen Scientists’ Intentions to Do Something About It

How we communicate the dangers of climate change may influence attitudes, intentions, and behaviors. Here we test two pairs of positive and negative framing statements with North American citizen scientists interested in gardening and birdwatching. Mentioning dangers for humans did not increase participants’ interest in taking personal action on climate change, but mentioning dangers for birds was highly effective. Highlighting the positive collective impacts of small behavioral changes also increased participants’ interest in taking personal action. These results suggest that while some dire messages are ineffective, those evoking concern for target species of significance to the learners may be as successful as positive messages.     

Microfluidic system for near-patient extraction and detection of miR-122 microRNA biomarker for drug-induced liver injury diagnostics

Drug-induced liver injury (DILI) results in over 100 000 hospital attendances per year in the UK alone and is a leading cause for the post-marketing withdrawal of new drugs, leading to significant financial losses. MicroRNA-122 (miR-122) has been proposed as a sensitive DILI marker although no commercial applications are available yet. Extracellular blood microRNAs (miRNAs) are promising clinical biomarkers but their measurement at point of care remains time-consuming, technically challenging, and expensive. For circulating miRNA to have an impact on healthcare, a key challenge to overcome is the development of rapid and reliable low-cost sample preparation. There is an acknowledged issue with miRNA stability in the presence of hemolysis and platelet activation, and no solution has been demonstrated for fast and robust extraction at the site of blood draw. Here, we report a novel microfluidic platform for the extraction of circulating miR-122 from blood enabled by a vertical approach and gravity-based bubble mixing. The performance of this disposable cartridge was verified by standard quantitative polymerase chain reaction analysis on extracted miR-122. The cartridge performed equivalently or better than standard bench extraction kits. The extraction cartridge was combined with electrochemical impedance spectroscopy to detect miR-122 as an initial proof-of-concept toward an application in point-of-care detection. This platform enables the standardization of sample preparation and the detection of miRNAs at the point of blood draw and in resource limited settings and could aid the introduction of miRNA-based assays into routine clinical practice.     

Sensitivity to Visual-Tactile Colocation on the Body Prior to Skilled Reaching in Early Infancy

Two experiments examined perceptual colocation of visual and tactile stimuli in young infants. Experiment 1 compared 4- (n = 15) and 6-month-old (n = 12) infants’ visual preferences for visual-tactile stimulus pairs presented across the same or different feet. The 4- and 6-month-olds showed, respectively, preferences for colocated and noncolocated conditions, demonstrating sensitivity to visual-tactile colocation on their feet. This extends previous findings of visual-tactile perceptual colocation on the hands in older infants. Control conditions excluded the possibility that both 6- (Experiment 1), and 4-month-olds (Experiment 2, n = 12) perceived colocation on the basis of an undifferentiated supramodal coding of spatial distance between stimuli. Bimodal perception of visual-tactile colocation is available by 4 months of age, that is, prior to the development of skilled reaching.     

Training mothers in elaborative reminiscing enhances children's autobiographical memory and narrative

This longitudinal intervention assessed children's memory at 2(1/2) years (short-term posttest; N=115) and their memory and narrative at 3(1/2) years (long-term posttest; N=100) as a function of maternal training in elaborative reminiscing when children were 1(1/2) to 2(1/2) years. At both posttests, trained mothers were more elaborative in their reminiscing than untrained mothers. At the long-term posttest, trained mothers were also more repetitive than untrained mothers. Children of trained mothers provided richer memories than children of untrained mothers at both posttests. Children of trained mothers also produced more accurate memories with researchers but only if they had high initial levels of self-awareness. Results are discussed with respect to theory and practice in autobiographical memory development.     

Cyberbullying victimisation and mental distress: testing the moderating role of attachment security,social support,and coping styles

Although it has been well established that cyberbullying leads to mental health problems, less is known about the factors that confer resilience to the adverse effects of cyberbullying among young people. To address this gap, adolescents aged 13–19 years (n = 476) completed a survey measuring cyberbullying victimisation, attachment styles, perceived social support, coping styles, and mental distress. Compared to non-victims, victims of cyberbullying experienced higher levels of depression and anxiety and endorsed more self-statements indicative of attachment anxiety. Peer support, security in attachment relationships, and the endorsement of positive coping strategies attenuated the positive relationship between cyberbullying victimisation and mental health difficulties. Family support did not appear to buffer adolescents from mental distress in this context. However, family support was the strongest bivariate predictor of reduced mental distress. Although peer relations should be the target of intervention programmes within school settings, the findings highlight the importance of including families in cyberbullying prevention programmes.     

Formative journeys of first-year college students: tensions and intersections with intercultural theory

Development of intercultural skills is recognized as an essential outcome of a college education, but in order to facilitate students' growth effectively, we must understand the points of the developmental journey at which students enter the college classroom. This study tests four hypotheses developed on the basis of leading models of intercultural development in relation to first-year students' levels of maturity, attitudes toward difference, capacity for productive interaction and emotions experienced in the face of difference. To test the hypotheses, we collected written narratives on a formative encounter with difference from 414 incoming students at the University of Minnesota. Each narrative was coded for an initial, intermediate or advanced stage of intercultural development, as well as for the outcomes of the interaction and emotions experienced in the course of the encounter. Findings indicate that: (1) only 21% of respondents display evidence of ethnorelative thinking; (2) the majority report very positive attitudes toward difference, but show evidence of veiled detachment and minimization; (3) there is no difference in reports of productive interaction between those who do and do not display mindfulness and (4) the emotions experienced at various stages of intercultural maturity do not yield a pattern of increasing comfort. We conclude that the points at which our students begin their intercultural journey may differ slightly from what is suggested by leading developmental models, and recommend adjusting the starting point of programming aimed at supporting intercultural competence development in college.     

How girls and boys expect disclosure about problems will make them feel: implications for friendships

Although girls disclose to friends about problems more than boys, little is known about processes underlying this sex difference. Four studies (Ns = 526, 567, 769, 154) tested whether middle childhood to mid-adolescent girls and boys (ranging from 8 to 17 years old) differ in how they expect that talking about problems would make them feel. Girls endorsed positive expectations (e.g., expecting to feel cared for, understood) more strongly than boys. Despite common perceptions, boys did not endorse negative expectations such as feeling embarrassed or worried about being made fun of more than girls. Instead, boys were more likely than girls to expect to feel "weird" and like they were wasting time. Sex differences in outcome expectations did help to account for girls' greater disclosure to friends.     

Maternal Judgments of Child Numeracy and Reading Ability Predict Gains in Academic Achievement and Interest

In a representative longitudinal sample of 2,602 Australian children (52% boys; 2% Indigenous; 13% language other than English background; 22% of Mothers born overseas; and 65% Urban) and their mothers (first surveyed in 2003), this article examined if maternal judgments of numeracy and reading ability varied by child demographics and influenced achievement and interest gains. We linked survey data to administrative data of national standardized tests in Year 3, 5, and 7 and found that maternal judgments followed gender stereotype patterns, favoring girls in reading and boys in numeracy. Maternal judgments were more positive for children from non-English speaking backgrounds. Maternal judgments predicted gains in children’s achievement (consistently) and academic interest (generally) including during the transition to high school.
