Environmental education technologies in a social void: the case of ‘Greendrive’     

Ana Delicado 《Environmental Education Research》2012,18(6):831-843

This article is based on a case study that follows the trajectory of a technological device aimed at environmental education from the engineering laboratory in which it was designed into the contexts in which it is used. ‘Greendrive’ is a driving simulator that accurately reproduces the performance of a vehicle in terms of fuel consumption and greenhouse gases emissions, in order to instill the principles of safe and environmentally friendly driving. The text is divided into three parts. The first part introduces the issue of transport behavior as one of the causes of climate change and the role of eco-driving in reducing emissions. The second part describes how a team of Portuguese engineering researchers developed the driving simulator and how a local authority and a consulting and training company are using it. Finally, the discussion part aims to show that despite the intentions of its creators and their clients, the driving simulator is unlikely, by itself, to generate changes in behavior. An information-deficit approach to environmental education that fails to consider the social embeddedness of human action and disregards the engagement of citizens has a very limited chance of success.  相似文献   

Solving arithmetic word problems: an analysis of classification as a function of difficulty in children with and without arithmetic LD     

García AI  Jiménez JE  Hess S 《Journal of learning disabilities》2006,39(3):270-281

This study was designed to determine a word problem difficulty classification in children with arithmetic learning disabilities (ALD; n = 104) in comparison with typically achieving students (n = 44). We tested variables such as (a) semantic structure (Change, Combine, Compare, and Equalize), (b) operation (subtraction and addition), and (c) position of the unknown quantity in the problem. Facet theory with multidimensional scaling techniques (MINISSA) was used to analyze the underlying dimensions in the responses of each group of participants. Our results indicate that although the word problem difficulty classifications for the 2 groups of children were different, the position of the unknown quantity had a greater influence on the level of difficulty of story problems than other variables. The noncanonical problems--specifically, those with the unknown term in the first place--although difficult for both groups of children, were the most difficult problems for children with ALD.  相似文献

IntroductionThe aims of study were to assess: 1) performance specifications of Atellica 1500, 2) comparability of Atellica 1500 and Iris, 3) the accuracy of both analysers in their ability to detect bacteria.Materials and methodsCarryover, linearity, precision, reproducibility, and limit of blank (LoB) verification were evaluated for erythrocyte and leukocyte counts. ICSH 2014 protocol was used for estimation of carryover, CLSI EP15-A3 for precision, and CLSI EP17 for LoB verification. Comparison for quantitative parameters was evaluated by Bland-Altman plot and Passing-Bablok regression. Qualitative parameters were evaluated by Weighted kappa analysis. Sixty-five urine samples were randomly selected and sent for urine culture which was used as reference method to determine the accuracy of bacteria detection by analysers.ResultsAnalytical specifications of Atellica 1500 were successfully verified. Total of 393 samples were used for qualitative comparison, while 269 for sediment urinalysis. Bland-Altman analysis showed statistically significant proportional bias for erythrocytes and leukocytes. Passing-Bablok analysis for leukocytes pointed to significant constant and minor proportional difference, while it was not performed for erythrocytes due to significant data deviation from linearity. Kappa analysis resulted in the strongest agreements for pH, ketones, glucose concentrations and leukocytes, while the poorest agreement for bacteria. The sensitivity and specificity of bacteria detection were: 91 (59-100)% and 76 (66-87)% for Atellica 1500 and 46 (17-77)% and 96 (87-100)% for Iris.ConclusionThere are large differences between Atellica 1500 and Iris analysers, due to which they are not comparable and can not be used interchangeably. While there was no difference in specificity of bacteria detection, Iris analyser had greater sensitivity.  相似文献   

Assessing the Impact of a Ceremony in Honor of the Body Donors in the Development of Ethical and Humanistic Attitudes among Medical Students     

Andrea Oxley da Rocha  Joao Lins Maués  Gabriel Antônio Flores Chies  Ana Paula da Silva 《Anatomical sciences education》2020,13(4):467-474

Activities related to body donation programs, such as donor memorial ceremonies, provide the opportunity to complement student training, especially with regard to the ethical and humanistic elements involved in medical training. This study sought to assess the impact of a ceremony in honor of the body donors has on ethical and humanistic attitudes in medical students. Medical students were surveyed about their perceptions of changes in themselves, respect for donors and donor families, and their relationship with patients. The effect of the students' contact with the family of the donor was analyzed in students who had contact with the cadaver in the dissection room and had either participated or not participated in the donor memorial ceremony. A total of 370 questionnaires were answered by first-, second-, and third-year medical students at the Federal University of Health Sciences of Porto Alegre in 2017. The students who participated in the ceremony presented more positive responses in relation to commitment to their studies, reflection on death, and positive development of empathy when compared to those who did not attend the ceremony. Most of the students that attended the ceremony suggested the event led to an improvement in the doctor–patient relationship. These results suggest that cadaver dissection with accompanied memorial ceremony involving contact with donor families is an effective means of fostering ethical and humanistic attitudes among medical students from the beginning of the course.  相似文献

Developmental Trends in Sexual Attraction Among Puerto Rican Early Adolescents in Two Contexts     

Katherine S. Elkington  Milton L. Wainberg  Maria Ramos-Olazagasti  Chen Chen  Ana Ortin  Glorisa J. Canino  Hector R. Bird  Cristiane S. Duarte 《Child development》2020,91(3):1044-1055

Sexual attraction (SA), the earliest stage of sexual orientation, is scarcely studied. This prospective study examined, over 3 years, prevalence, changes in SA, and the role of context, among 946 Puerto Rican youth, aged 11–13 years at initial assessment in the South Bronx (SBx), New York City, and Puerto Rico (PR). Overall, 98.1% of boys and 95.3% of girls reported opposite-sex only SA at some point, whereas 13.8% of girls and 12.0% of boys reported any-same SA. Opposite-sex only SA increased over time, whereas other SAs decreased except for any same-sex SA among SBx girls. Girls in the SBx and younger youth in PR reported more any same-sex SA. Context and culture may play a role in the developmental trajectories of adolescents’ SA.  相似文献

Efficacy of Cognitive‐Behavioral therapy in the treatment of children with adhd,with and without aggressiveness     

Ana Miranda  María Jesús Presentacin 《Psychology in the schools》2000,37(2):169-182

The objectives of this study were twofold: to show the efficacy of a cognitive‐behavioral self‐control therapy on children with ADHD and to determine whether the combination of training in self‐control with training in anger management has better outcomes on two subgroups of hyperactive children, aggressive and nonaggressive. Thirty‐two children with ADHD, 16 aggressive and 16 nonaggressive, participated in the research. We applied a cognitive‐behavioral self‐control training, which included self‐instructional training via modeling and behavioral contingencies, to 16 of the 32 hyperactive children. The other 16 hyperactive children were taught the same program, but combined with anger management training. The interventions were carried out by two therapists each taking care of four groups, one of each in the following conditions: hyperactive with the cognitive‐behavioral self‐control therapy, hyperactive with the combined treatment, hyperactive‐aggressive with the cognitive‐behavioral self‐control therapy, and hyperactive‐aggressive with the combined treatment. The results indicated important improvements on several measures in all treated groups. Furthermore the improvements of children with aggressiveness were slightly better, according to the parents, with the combined treatment than without it. The data provide support for including anger management training in the cognitive‐behavioral interventions for hyperactive‐aggressive students. © 2000 John Wiley & Sons, Inc.  相似文献   

Menstrual cycle alters training strain,monotony, and technical training length in young     

Gislaine Cristina-Souza  Ana C. Santos-Mariano  Carla C. Souza-Rodrigues  Raul Osiecki  Sandro F. Silva  Adriano E. Lima-Silva 《Journal of sports sciences》2019,37(16):1824-1830

The menstrual cycle (MC) phases carry to several psychophysiological alterations; however, no study has investigated the impact of MC phases on training load or technical training. In the present study, we investigated the effect of the follicular phase (FP), ovulatory phase (OP), and luteal phase (LP) on training load and technical training in young athletes. Twelve female athletes performed regular daily training sessions with the rating of perceived exertion (RPE) and duration being registered every session. Training impulse (TRIMP), monotony and strain were calculated. MC symptoms, RPE, and duration were also measured during technical training, which was carried out on a specific day during each phase. The TRIMP was not affected by MC phases during regular training (p > .05), but training monotony and strain were higher in FP compared to OP (p < .05). During the technical training, MC phases did not affect RPE (p > .05), but the session was longer in both FP and LP, compared to OP (p < .05). MC symptoms were exacerbated in FP compared to both OP and LP (p < .05). These findings suggest that MC disorders were elevated during FP, which indicate that monitoring MC phases might provide important feedbacks for programming training and expected results during competitions.  相似文献   

‘Bloomers’ and the British World: Dress Reform in Transatlantic and Antipodean Print Culture, 1851–1950     

Ana Stevenson 《Cultural and Social History》2017,14(5):621-646

The ‘bloomers’ are rarely considered beyond their 1851 origins in the United States and subsequent appearance in Britain. This article expands dress reform scholarship by analysing print culture elsewhere in the British world, specifically Australia and New Zealand. The colonial press manufactured controversy over this fashion – a perceived transgression of gender norms – even though antipodean women rarely sported the outfit. This article focuses on the dress reform lectures and writings of Amelia Bloomer, Caroline Dexter and Dr Mary Walker. While certain continuities resurfaced alongside the bloomer-like rational dress popularised in the bicycling culture of the 1890s, dress reform was largely deemed far less controversial by the turn of the twentieth century.  相似文献
