Making sense of carbon footprints: how carbon literacy and quantitative literacy affects information gathering and decision-making

Abstract

Popular media often reports on the carbon footprint of certain activities, items or people. We were curious to explore how people make sense of these news pieces, and specifically, whether and how carbon literacy (CL) and quantitative literacy (QL) influences their reasoning. We interviewed and surveyed students of various backgrounds using simulated news pieces of three carbon footprints: that of Facebook, that of the US dairy industry, and that of the US chocolate industry. We found that being highly carbon or quantitatively literate influenced participants’ reaction – but only while they were gathering information about the prompts. The effect of literacies disappeared when they were asked to decide whether the carbon footprint was worrisome or which they would tackle first as a policy-maker. We describe and categorize the strategies students used to make sense of carbon footprints, and link the frequency of using particular strategies to their carbon and quantitative literacy. Implications for future research and environmental education are discussed.     

Effects of Alternated Basketball Competition on Perceived Competence in Adolescents with Intellectual Disabilities Over a Period of 13 Months: A research note

The purpose of this study was to examine the effects of alternated (segregated and integrated) basketball competition on two domains of perceived competence and on general self-worth. Participants were 24 adolescent males with intellectual disabilities divided equally into three groups: (a) those involved in basketball in an alternated sport competition, (b) those involved in adapted physical activity, and (c) those who were sedentary. The experimental treatment lasted for 13 months. For the sport competition group this involved 2 hr of training each week and 12 competitive meets. We administered Harter's (1985) Self-Perception Profile for Children 13 times to determine changes in perceived competence and general self-worth. The results indicate no significant changes for the different groups in the two domains of perceived competence and in general self-worth over 13 months.     

Do Consonant Sonority and Status Influence Syllable-Based Segmentation Strategies in a Visual Letter Detection Task? Developmental Evidence in French Children

This article queries whether consonant sonority (sonorant vs. obstruent) and status (coda vs. onset) within intervocalic clusters influence syllable-based segmentation strategies. We used a modified version of the illusory conjunction paradigm to test whether French beginning, intermediate, and advanced readers were sensitive to an optimal “sonorant coda–obstruent onset” sonority profile within the syllable boundaries as a cue for a syllable-based segmentation. Data showed that children used a syllable-based segmentation that improved with reading skills and age. The results are discussed to support that the visual letter detection within pseudowords primarily and early relies on acoustic-phonetic cues within the syllable boundaries, whereas the syllable effect seems to be developmentally constrained by reading skills and age.     

Effects of physical activities that induce moderate external loading on bone metabolism in male athletes

Sports characterized by little or moderate weight bearing or impact have a low osteogenic effect. However, the action of such sports on bone turnover remains unclear. The objective of this study was to determine the effect on bone remodelling of physical activities that induce moderate external loading on the skeleton. Thirty-eight male athletes aged 18–39 years (cyclists, n?=?11; swimmers, n?=?13; triathletes, n?=?14) and 10 age-matched sedentary controls aged 22–35 years participated in the study. The study combined measurement of bone mineral density by dual-energy X-ray absorptiometry and bone turnover assessment from specific biochemical markers: serum bone-specific alkaline phosphatase, osteocalcin, urinary type I collagen C-telopeptide and calcium. Compared with the controls and swimmers, adjusted bone mineral density was higher (P?<?0.05) in triathletes at the total proximal femur and lower limbs. No differences in bone mineral density were found between cyclists, swimmers and controls. Compared with controls, osteocalcin was higher (P?<?0.05) in triathletes and swimmers and urinary type I collagen C-telopeptide was higher in swimmers only. Serum bone-specific alkaline phosphatase was lower (P?<?0.05) in cyclists than in all other groups. In conclusion, an osteogenic effect was found only in triathletes, mainly at bone sites under high mechanical stress. Bone turnover differed in athletes compared with controls, suggesting that bone turnover may be sport-practice dependent. Despite some encouraging observations, it was not possible to show that changes in the bone remodelling process were sport-discipline dependent.     

Intermanual transfer of shapes in preterm human infants from 33 to 34 + 6 weeks postconceptional age

This study investigated the ability of preterm infants to learn an object shape with one hand and discriminate a new shape in the opposite hand (without visual control). Twenty-four preterm infants between 33 and 34 + 6 gestational weeks received a tactile habituation task with either their right or left hand followed by a tactile discrimination task in the opposite hand. The results confirmed that habituation occurred for both shapes and both hands. Infants subsequently held the novel shape longer in the opposite hand. The results reveal that preterm infants are capable of intermanual transfer of shape information. In spite of the immaturity of the corpus callosum in preterm infants, its development seems to be sufficient to allow some transfer of information between both hands.     

Learning Within and Beyond the Classroom: Compulsory School Students Voicing Their Positive Experiences of School

The aim of this study was to describe, reflect upon, and create a deeper understanding of aspects relevant for promoting a positive school environment from a student perspective. The data was analyzed by using an inductive phenomenological method and based on written responses from 200 Swedish students from grades 5–9. The results indicated that the students found aspects within, as well as beyond, the classroom relevant for a positive school environment. For instance, outings were considered relevant for building and maintaining friendships and for learning processes. Moreover, the students discussed formal and informal conditions and considered social as well as structural circumstances important for having a good time in school. The relation between learning and well-being was also emphasized by the students.     

Learning styles and approaches to learning in excellent and average first-year university students

We assessed the learning approaches and learning styles of a sample of 148 excellent students selected from 11 degrees from nine centers of the Polytechnic University of Valencia (Spain), and we compared the results with those of a sample of 133 average students from the same centers. We found that excellent students took deeper approach than average students and that they preferred reflective and theoretical learning styles. Average students adopted a more surface approach, and they preferred active and pragmatic learning styles. Greater academic achievement was related to the deep approach and to the reflective and theoretical learning styles. Poorer academic achievement was related to the surface approach and an active style. University professors may reinforce the deep approach by placing high aims for students which go well beyond reproducing knowledge but use other complementary methods other than expository teaching: problem solving, case studies, designing projects, raising questions, discussion and negotiation in the classroom, etc. To accomplish this, teachers must encourage students to be committed, and these methods help do that. It also helps to introduce more demanding evaluation procedures which do not merely involve repeating what has been learnt, but include training guidance that offers students feedback.     

Supervising mentors’ lived experience on supervision in teaching, nursing and social care education. A participation-oriented phenomenological study

Research concerning the supervisor role in separate educational programmes has been undertaken, but cross-professional studies are few. The aim of this study was to explore the lived experience of supervising mentors in Sweden during the practice-based, off-campus sections of the education in teaching, nursing, and social care. The study used a participatory phenomenological approach in which four researchers and nineteen supervising mentors worked together in the research process which was accomplished in four different phases. The data collecting method used was interview. The results constituted a main essence entitled “Struggle of power and control of professional quality enhancement” built upon four themes: “Constitutes a motivating force”, “Feelings of responsibility”, “Feelings of frustration” and “Wishes for alteration”. Conclusions from the study are that communication, information and contact between the professionals in the fields and university teachers need to be strengthen to keep up supervising mentors’ motivating force and to give them support.     

Glenohumeral internal rotation deficit in table tennis players

ABSTRACT

Table tennis requires rapid and extreme movements that may result in shoulder adaptations, such as glenohumeral internal rotation deficit, which is a risk factor for several injuries. This study compared range of motion of internal and external rotation and total rotation motion of glenohumeral joint between dominant and non-dominant shoulders of table tennis players. This is a cross-sectional observational study. Twenty healthy male table tennis players that were enrolled in an official table tennis league took part in this study (mean age: 22.9 ± 12.9 years, time of sports practice: 6.2 ± 7.12 years). Measurements of passive glenohumeral external rotation and internal rotation were taken with the individuals in the supine and sidelying positions. Total rotation motion was calculated by summing external and internal rotations. The dominant side showed decreased internal rotation when compared to non-dominant side in both supine (mean difference: 14.9°, p = 0.02) and sidelying positions (mean difference: 16.3°, p = 0.01). No significant difference (p > 0.05) was found for external rotation and total rotation motion between dominant and non-dominant shoulders. The findings indicate that table tennis players exhibit glenohumeral internal rotation deficit of dominant shoulder.     

Navigating between an emic and an etic approach in ethnographic research. Crucial aspects and strategies when communicating critical results to participants

There is a fundamental tension in ethnographic research between trying to understand participants from within their own perspective and viewing them with greater distance. With this in mind, the aim of this article is to describe how a reflexive communication model was developed during the study of El Sistema Gothenburg, and to discuss aspects and strategies that are crucial when navigating between an emic and an etic approach. It is argued that by reflexive communication, researchers can make their results useful for participants and that reflecting upon the relationship is even more important when communicating critique. With the help of this model, communication of critical results was facilitated by the establishment of an integrative approach that combined the insiders’ and outsiders’ perspectives and was based on the formation of a strong relationship between the researchers and the participants, as well as by the participants’ own cultivation of theoretical understanding.
