This study investigates how prime-time television news portrayed attributions of responsibility for climate change policy issues in the United States, China, and Canada. In analyzing news coverage of the 2009 climate change summit in Copenhagen, we distinguish between causal and treatment responsibility. Additionally, we develop frames to test Cerutti's conceptualization of responsibility attribution (2010). The results suggest that television news in the 3 countries portrayed treatment responsibility differently. The prominence of morality, global justice, and national efficacy frames varied across countries, and these conditions were associated with the treatment responsibility frame, partially lending support to the validity of Cerutti's conceptualization.  相似文献   

The Writing on the Wall: A Content Analysis of College Students' Facebook Groups for the 2008 Presidential Election     

Juliana Fernandes  Magda Giurcanu  Kevin W. Bowers  Jeffrey C. Neely 《Mass Communication and Society》2013,16(5):653-675

This study looks at student Facebook groups supporting the 2008 presidential candidates, John McCain and Barack Obama, from largest land-grant universities in seven battleground states. The findings of a content analysis of wall posts show that students are using Facebook to facilitate dialog and civic political involvement. In opposition to pro-McCain groups, pro-Obama groups have wider time frame coverage and demonstrate substantively higher site activity. Political discussions related to the political civic process, policy issues, campaign information, candidate issues, and acquisition of campaign products dominate across groups and election seasons. An examination of the content of wall posts based on the four categories of the Michigan Model of voting behavior (partisanship, group affiliation, candidate image, and political/campaign issues) reveals that in the primary season, pro-Obama groups focus mostly on short-term topics (candidate image and campaign issues), whereas pro-McCain groups focus mostly on long-term topics (partisanship and group affiliation). The overall findings of this study suggest that youth online communities actively follow campaigns and post comments that foster the political dialog and civic engagement.  相似文献   

Unique Correlation Between Mutated Citrullinated Vimentine IgG Autoantibodies and Markers of Systemic Inflammation in Rheumatoid Arthritis Patients     

Walid E. Zahran  Magda I. Mahmoud  Kamal A. Shalaby  Manal H. Abbas 《Indian journal of clinical biochemistry : IJCB》2013,28(3):272-276

Rheumatoid arthritis (RA) is the most common inflammatory systemic autoimmune disease, primarily affecting the peripheral joints. Anti-mutated citrullinated vimentin autoantibodies (anti-MCV) of IgG isotype were shown to be a useful diagnostic marker of RA especially in RA patients who were anti-cyclic citrullinated protein autoantibodies (anti-CCP) negative. Nevertheless, published data correlates rheumatoid factor (RF), anti-CCP or anti-MCV antibodies with either erythrocyte sedimentation rate (ESR) or serum C-reactive protein (CRP) as markers of disease activity, not investigated the possible correlations of RA autoantibodies towards ESR and CRP in comparison. Herein, we aim to evaluate the usefulness of anti-MCV as a dependable marker in established RA compared with anti-CCP and RF antibodies and to examine correlations between RF, anti-CCP and anti-MCV antibodies towards ESR and serum CRP. Serum RF-IgA, RF-IgM, anti-CCP and anti-MCV levels were measured in 30 patients with RA and 40 patients with other autoimmune diseases (non-RA) compared with 20 normal subjects. Specificity, sensitivity and AUC for RF antibodies, anti-CCP and anti-MCV were calculated towards RA diagnosis. Our results showed that ESR and CRP had significantly higher values in both RA and non-RA patients compared with our healthy controls with observed significant increment in RA patients compared with non-RA patients. An important finding from our study is that 33.3 % of RA patients were anti-CCP negative but being positive towards anti-MCV. Also, in-between 36.7 up to 40 % of RA patients were RF-IgA and RF-IgM negative while being anti-MCV positive. Anti-MCV antibodies showed the highest specificity and sensitivity (97.5 and 86.6 %, respectively) towards RA diagnosis with the highest AUC value (0.920) compared with anti-CCP and RF antibodies. Correlation analyses revealed that there was no significant correlation between ESR along with CRP towards RF-IgA, RF-IgM and anti-CCP while profound highly significant correlation exhibited between ESR and CRP towards anti-MCV data (r = 0.879 and 0.994, respectively). Thus, our data suggest that the assessment of serum anti-MCV autoantibodies along with ESR and CRP considered as a simple laboratory regime for monitoring RA patients to assess and follow-up disease activity. The addition of anti-MCV autoantibodies to serologic markers in the ACR/EULAR classification criteria for RA will add points for patients with negative anti-CCP and RF antibodies.  相似文献

The impact of personal educational experiences and communication practices on the construction of deaf identity in Cyprus     

Hadjikakou K  Nikolaraizi M 《American annals of the deaf》2007,152(4):398-414

The aim of the study was to investigate for the first time the impact of educational experiences on the development of Cypriot deaf people's identity. To obtain relevant information in depth, semistructured interviews were conducted with 24 Cypriot deaf individuals ages 19-54 years who had graduated from a variety of school settings. The findings indicated that the type of school, and the academic and social experiences shared within the school between the participants and their classmates and teachers, played a crucial role in these deaf individuals' identity development. The findings have implications for curriculum development for deaf pupils, and for parents' counseling about their deaf children's development of "healthy" identities.  相似文献   

Physical activity, nutrition, screen time and sleep associated with body weight and physical condition in young children     

Monique L’Hoir PhD  Susanne Tetteroo BSc  Magda Boere-Boonekamp MD  PhD  Elly Kloeze MSc  Ingrid Bakker PhD  Francisca Galindo Garre PhD  Prof. Dr. Roland Naul 《Sportwissenschaft》2013,43(2):116-123

The aim of this cross-sectional study was to explore the possible relationship between (un)healthy behaviour and (over)weight and physical condition in families with young children (4–7 years), in a village (30,000 inhabitants) in the eastern part of the Netherlands, close to Germany. It is one of two pilot studies as a precursor of a cross-border project including six Dutch and six German villages, to counteract physical inactivity and possible future metabolic problems. In total, 459 children of five elementary schools and their parents were included. Parents were requested to fill in a questionnaire on the nutritional, physical, sedentary, and sleeping behaviour of their child. Relevant background characteristics were obtained and lifestyle classifications were made. At school, the children's height and weight (body mass index (BMI)) were measured, as well as their physical condition (two tests) and basic motor abilities (four physical exercise tests). The relationship between the standardized BMI z-scores and physical condition test scores, and nutritional, physical, sedentary and sleeping habits was analysed using independent sample t-test, bivariate correlation analysis and multiple regression analysis. Latent class analysis was used to identify clusters of people based on their nutritional, physical and sleep habits. Of the parents, 376 (82?%) were willing to fill out the questionnaire. High birth weight and a high BMI of the mother and/or father correlated with a higher BMI of the child (ρ?=?0.28, p?<?0.001; ρ?=?0.13, p?=?0.016; and ρ?=?0.23, p?<?0.001, respectively). Daily playing outside, eating small cookies (compared with large cookies) and no sleeping problems (no waking up during the night) were related to low BMI levels (no overweight) [ρ?=???0.14, p?=?0.005; ρ?=???0.12, p?=?.020; t(364)?=?1.81, p?=?0.072 (trend), respectively]. Daily playing outside (frequency and duration) and being a member of a sports club were related to positive scores on the physical condition tests [ρ?=?0.20, p?<?0.001; t(365)?=???2.99, p?=?0.003, respectively]. High levels of television (TV) watching and general sleeping problems were related to a less optimal physical condition [ρ?=???0.09, p?=?0.076 (trend); and ρ?=???0.10, p?=?0.059 (trend), respectively]. A latent class analysis revealed three clusters: 46?% of the sample belonged to the ‘healthy group’ concerning nutrition, sedentary lifestyle and TV/personal computer (PC) use; 17?% to the ‘less healthy’ group and 37?% to a group with nutrition and physical activity habits close to the healthy group, but with low conditional probabilities for the sleeping items. Conducting a pilot study before the start of a binational intervention study gives a blueprint for the final questionnaire, and clues for tailored interventions in the schools, as proposed in the approach of ‘Gesunde Kinder in gesunden Kommunen’ (GKGK). The results of a latent class analysis underscore that interventions should exist of a multi-component strategy, focusing on promoting physical activity, healthy nutrition habits and appropriate sleep.  相似文献   

Institutional transformation at South African universities: Implications for academic staff     

Magda Fourie 《Higher Education》1999,38(3):275-290

In South Africa the restructuring of the higher education system and the transformation of higher education institutions are located within the country's broad political and socio-economic transition to democracy. This paper focuses particularly on institutional transformation, and pays attention to the implications of the process of transformation for academic staff.The following five interlinked and interdependent issues characterizing institutional transformation in South African higher education are identified:democratising the governance structures of institutionsincreasing access for educationally and financially disadvantaged studentsrestructuring the curriculumfocusing on developmental needs in research and community serviceredressing inequalities in terms of race and gender.Although the overall effect of institutional transformation is experienced rather negatively by many academic staff members, the paper concludes that academics have to be empowered by means of staff development to remain active partners in the transformation process.  相似文献

The Experiences of Foundation Phase Teachers Regarding Reading Literacy Interventions at an Underperforming School in Gauteng Province     

J. Fourie  M. Sedibe  M. Muller 《Interchange》2018,49(1):85-109

South Africa’s education system has been characterized by various curriculum changes since 1997 given that basic education is a priority of this government and policies have specifically been aimed at improving the overall standard of education in the country. Despite these curriculum changes, the findings of tests such as the Progress in International Reading Literacy Study (PIRLS) of 2006 revealed that South African learners had obtained the lowest overall reading literacy average out of 45 participating educational systems and the South African Consortium for Measuring Educational Quality (SACMEQ) highlighted that the majority of children in South Africa’s primary schools are not even reading at the minimal required level. In view of the publicised results of PIRLS 2006 and SAQMEQ 2008, several reading literacy interventions, known as the Foundations for Learning (FFL), Annual National Assessments (ANA) and Gauteng Province Literacy and Mathematics Strategy (GPLMS) have been launched in the past few years to improve literacy and numeracy results in the country. Notwithstanding, the increasing prevalence of low reading literacy results in South Africa raised questions about the effectiveness of interventions intended to improve reading results (in: GDE, Gauteng Primary Literacy Strategy, 2010–2014, Government Printer, Pretoria, 2010). Given the background of this study, the primary aim was to establish the essence of the participant FP teachers’ lived experiences regarding the implementation of interventions for reading literacy such as FFL, ANA and GPLMS in order to theorise about the effectiveness of these interventions. The secondary purpose was to add to the body of knowledge concerning FFL, ANA and GPLMS implemented as interventions to improve reading literacy results in South Africa. To achieve these purposes, a phenomenological case study was conducted at one of the 832 identified underperforming schools in Gauteng with eleven Foundation Phase teachers. Three methods were used to collect data namely focus group interviews, non face to face interviews and artefacts. The focus group interviews were held in grade context whilst interview forms were given to each of the eleven participants and they were requested to complete it comprehensively in the absence of the researcher. Data from all interviews were corroborated through selected artefacts which were mentioned during the interviews or discovered by the researcher throughout the study. The key findings of this study show that the participants perceived FFL, ANA and GPLMS as mandatory interventions for reading literacy that are unwanted and repetitious. Most importantly the participants deemed ANA as unreliable and unfair whilst FFL and GPLMS were deemed unsuitable for the diverse needs of the learners at this school. In view of the findings, this study concluded that there is limited value in providing mandatory interventions to teachers with the intent of improving the reading literacy results of learners with diverse needs that are contextually bound.  相似文献   

Self-Directed Learning in Problem-Based Learning and its Relationships with Self-Regulated Learning   总被引：4，自引：3，他引：1  

Sofie M. M. Loyens  Joshua Magda  Remy M. J. P. Rikers 《Educational Psychology Review》2008,20(4):411-427

This study investigated the role of self-directed learning (SDL) in problem-based learning (PBL) and examined how SDL relates to self-regulated learning (SRL). First, it is explained how SDL is implemented in PBL environments. Similarities between SDL and SRL are highlighted. However, both concepts differ on important aspects. SDL includes an additional premise of giving students a broader role in the selection and evaluation of learning materials. SDL can encompass SRL, but the opposite does not hold. Further, a review of empirical studies on SDL and SRL in PBL was conducted. Results suggested that SDL and SRL are developmental processes, that the “self” aspect is crucial, and that PBL can foster SDL. It is concluded that conceptual clarity of what SDL entails and guidance for both teachers and students can help PBL to bring forth self-directed learners.  相似文献
