Protection or Participation?     

Anna Grøndahl Larsen 《Journalism Practice》2017,11(7):893-908

Children’s status as a particularly vulnerable group in society implies a journalistic obligation to shed light on children’s stories and listen to their perspectives, but their vulnerable position also means they deserve protection from potentially harmful news coverage. Based on a close-reading of two extensively covered news serials concerning irregular migrant children facing deportation, and on in-depth interviews with journalists, editors, and key actors working on behalf of irregular migrant children, the present article sheds light on how journalists balance competing, ethical, professional, and organizational concerns when reporting on issues concerning children. The article shows that while journalists say they are aware of the ethical aspects concerning extensive media exposure of young children, they justify the reporting by foregrounding children as innocent victims of the immigration system and by highlighting the journalistic obligation of shedding light on the wrongdoings of this system. The potential burden of media exposure is relativized as less harmful than the alternative—deportation. Theoretically, the article contributes to the literature on children in the news media, human-interest stories and journalism, and the role of journalism reporting vulnerable groups.  相似文献   

Degradation of collagen in parchment under the influence of heat-induced oxidation: Preliminary study of changes at macroscopic,microscopic, and molecular levels     

Kathleen Mühlen Axelsson  René Larsen  Dorte V.P. Sommer  Rikke Melin 《文物保护研究》2016,61(1):46-57

This paper examines the impact of heat-induced oxidation for new and historical parchment with the purpose of improving diagnostic tools for use in practical parchment conservation. Oxidation was generated by heat aging at 120°C in a dry oven for 24, 48, and 96 hours, respectively. The degradation was assessed on all samples at macrolevel by measuring color changes, at microlevel by measuring the shrinkage temperature as well as by performing a visual assessment of the fibers’ morphology and determining the amount of damaged fibers, and finally, at molecular level where amino acid analysis was used to reveal changes in the oxidized collagen. The study shows that the heat-induced oxidation leads to significant color changes, decrease in hydrothermal stability, as well as changes in the amino acid composition. Surprisingly, the results show that the historical parchment is more sensitive towards dry heat oxidation on a molecular level than is the new parchment. Furthermore, for the first time, we can show that physical damage reflected in the morphological characteristics of fibers can be attributed to oxidation by dry heat.  相似文献

A Study of Cluster Grouping     

Suzanne W. Larsen  James R. Montgomery 《Journal of Experimental Education》2013,81(4):30-36

The increasing size of most universities in the United States at times has led to efforts to counteract largeness by creating many small units within the larger one. The following study reports on a pilot study to evaluate the effectiveness of a grouping pattern in which freshman students had their class schedules arranged in such a way as to have at least three sections (courses) in common with others in their respective group.  相似文献   

The Case for a Middle School College Readiness Index: Rejoinder to Lazowski,Barron, Kosovich,and Hulleman and Mattern,Allen, and Camara     

Matthew N. Gaertner  Katie Larsen McClarty 《Educational Measurement》2016,35(3):35-37

This rejoinder provides a reply to comments on a middle school college readiness index, which was devised to generate earlier and more nuanced readiness diagnoses to K‐12 students. Issues of reliability and validity (including construct underrepresentation and construct‐irrelevant variance) are discussed in detail. In addition, comments from Lazowski et al. and Mattern et al. provide a useful summary of areas where more college readiness research is needed. This rejoinder elaborates on those essential next steps, including deploying readiness indicators in school settings. Advances in the measurement of noncognitive skills will require more validity research using more contemporary data from authentic school settings. Still, the middle school college readiness index is a promising proof of concept, demonstrating the utility of diverse, early measures to support targeted, timely interventions.  相似文献

Fostering Self‐Regulation of Students with Learning Disabilities: Insights from 30 Years of Reading Comprehension Intervention Research          下载免费PDF全文

Sheri Berkeley  Anna Larsen 《Learning disabilities research & practice》2018,33(2):75-86

Thirty years of intervention research on the effects of reading comprehension strategies for students with learning disabilities was reviewed in this quantitative synthesis. Specifically, researchers targeted studies that contained self‐regulated learning components. A systematic search yielded 18 studies from nine research journals that met specified inclusion criteria. Studies were evaluated for methodological quality and to identify types of instructional and self‐regulation components within interventions. Large effect sizes were found immediately after instruction and after a time delay, suggesting that instruction in reading comprehension strategies that contain self‐regulation components may have a long lasting impact on student performance. Implications for research and practice are discussed.  相似文献   

Immune disorders and dyslexia     

Finn Egil Tønnessen  Torleiv Høien  Ingvar Lundberg  Jan Petter Larsen 《Reading and writing》1994,6(2):151-160

The Geschwind-Behan-Galaburda hypothesis of cerebral lateralization postulates an association between immune disorders and learning disabilities. So far, the empirical evidence for such a relationship has been ambiguous. The present study is an attempt to investigate the hypothesis in a population where all the individuals were affected by immune disorders. Thus, 29 students in a special school for asthmatic children (total number of students in the school: 32) were investigated. A number of reading tests with special focus on word decoding were administered. The parents filled in a detailed questionnaire on the prevalence of reading difficulties and immune disorders among the other family members. The proportion of students with reading problems — especially phonological problems — was much higher than would be expected in a normal population. Among the family members we also found an elevated incidence of both reading problems and immune disorders. A cautious interpreptation of these findings leads to tentative and partial support of the Geschwind-Behan-Galaburda hypothesis.  相似文献   

The Role of Alternative Theories and Anomalous Evidence in Children’s Scientific Belief Revision     

Patricia A. Ganea  Nicole E. Larsen  Vaunam P. Venkadasalam 《Child development》2021,92(3):1137-1153

Children’s naive theories include misconceptions which can interfere with science learning. This research examined the effect of pairing anomalies with alternative theories, and their order of presentation, on children’s belief revision. Children believe that heavy objects sink and light ones float. In a pre-, mid-, and post-test design, 5-year-olds (N = 96) were assigned to one of two conditions, where they were either exposed to an alternative theory about buoyancy and then observed anomalies (Explanation-First), or the reverse (Anomalies-First). At mid-test, children were more likely to revise their beliefs after exposure to an alternative theory than anomalies alone. At post-test, children revised their naïve belief when they had access to an alternative theory before the anomalous evidence than in the opposite order.  相似文献   

Exploring the Associations Between Delayed School Entry and Achievement in Primary and Secondary School     

Sally A. Larsen  Callie W. Little  William L. Coventry 《Child development》2021,92(2):774-792

This research investigated whether delayed school entry was associated with higher achievement in national tests of reading and numeracy in Grades 3, 5, 7, and 9 (n = 2,823). Delayed entry was related to advantages in reading (0.14 SD) and numeracy (0.08 SD) at Grade 3, although little variance was explained (1%–2%). This slight advantage persisted for both domains in Grades 5 and 7, albeit with smaller effects. In Grade 9 there was no association between delayed entry and either reading or numeracy. Exploratory analyses with subsamples in each grade (n = 424–667) revealed no associations between delayed entry and achievement after controlling for inattention and hyperactivity, and negative associations between inattention and achievement in all grades in both domains (−0.33, −0.49 SD).  相似文献
