Hostile Public Effect: Communication Diversity and the Projection of Personal Opinions Onto Others     

Magdalena Wojcieszak  Hernando Rojas 《广播与电子媒介杂志》2013,57(4):543-562

In the context of Colombia, a society with high levels of polarization, this study finds that the projection of individual ideological leanings onto others diminishes with ideological extremity. The findings also show that communication diversity, understood as heterogeneous discussion networks and exposure to ideologically dissimilar news media, is negatively related to projecting one's leanings on public opinion at large. This study further suggests that expressive Internet uses do not predict projection, and that informational uses are associated with reduced projection. Moreover, dissimilar media exposure moderates the relationship between extremism and projection by further reducing projection among ideologically extreme respondents. Discussion heterogeneity does not exert a similar moderating effect. Implications for future research are discussed.  相似文献   

Predicting LD on the basis of motivation, metacognition, and psychopathology: an ROC analysis     

Sideridis GD  Morgan PL  Botsas G  Padeliadu S  Fuchs D 《Journal of learning disabilities》2006,39(3):215-229

We examined how strongly motivation, metacognition, and psychopathology acted as predictors of learning disabilities (LD). The results from five studies suggested that level of motivation (as shown through self-efficacy, motivational force, task avoidance, goal commitment, or self-concept) was highly accurate in classifying students with or at risk for LD. Metacognition and psychopathology were also strong predictors. Classification accuracy using receiver operating characteristic (ROC) curves ranged between 77% and 96%. These rates were much higher than the chance-level (i.e., 50%-55%) rates sometimes yielded by cognitive indices. Linear discriminant function (LDF) analysis substantiated classification accuracy. These results suggest that motivation, metacognition, and psychopathology are strong predictors of LD. Understanding the influence of these characteristics may help researchers and practitioners more accurately screen and treat students with LD.  相似文献

The aim of this article was fourfold: first, to determine whether there are significant differences between students with (N= 173) and without learning disabilities (LD; N= 172) in the dimensions of self‐concept, causal attributions, and academic goals. Second, to determine whether students with LD present a uniform attributional profile or whether there are subgroups of attributional profiles among students with LD. Third, to explore differences between these profiles on the dimensions of self‐concept, academic goals, perception of competence‐incompetence, persistence when faced with failure, peer relationships, and academic achievement. Fourth, to determine whether there are significant differences in the dimensions of self‐concept and academic goals between NLD students and the different LD subgroups. The results indicate the existence of two very distinct attributional profiles in students with LD (Helplessness Profile and Adaptive Profile). The implications of these data with regard to theory and research, as well as educational practice, are discussed.  相似文献   

School head teachers’ views of the drive towards educational innovation in Catalonia / La visión de los directores de escuela sobre el impulso de la innovación educativa en Cataluña

Abstract

Today, educational change and innovation are a clear priority in educational centres across the world. This article analyses the strengths and opportunities presented by the process of educational innovation taking place in Catalonia from the perspective of school head teachers, employing a quanti-qualitative methodology using 227 surveys and 29 semi-structured interviews. The results locate the innovation process in a phase characterized by efforts aimed at updating existing practice, resistance to change generated by the system itself, and a lack of systematic reflection on current practice. Two strengths of the process reported relate to its scale and transversality across the whole territory on the one hand, and the importance that collaboration between teachers and schools is having in order to facilitate innovation. Other aspects highlighted are: the need to invest more planning in innovation processes; the need for the Deparment of Education to reflect on its own role within the process; and, finally, the need to develop the role of technologies as facilitators of innovation and communication.  相似文献   

Discrimination between Demodex folliculorum (Acari: Demodicidae) isolates from China and Spain based on mitochondrial cox1 sequences     

Ya-e Zhao  Jun-xian Ma  Li Hu  Li-ping Wu  Manuel De Rojas 《Journal of Zhejiang University. Science. B》2013,14(9):829-836

For a long time, classification of Demodex mites has been based mainly on their hosts and phenotypic characteristics. A new subspecies of Demodex folliculorum has been proposed, but not confirmed. Here, cox1 partial sequences of nine isolates of three Demodex species from two geographical sources (China and Spain) were studied to conduct molecular identification of D. folliculorum. Sequencing showed that the mitochondrial cox1 fragments of five D. folliculorum isolates from the facial skin of Chinese individuals were 429 bp long and that their sequence identity was 97.4%. The average sequence divergence was 1.24% among the five Chinese isolates, 0.94% between the two geographical isolate groups (China (5) and Spain (1)), and 2.15% between the two facial tissue sources (facial skin (6) and eyelids (1)). The genetic distance and rate of third-position nucleotide transition/transversion were 0.0125, 2.7 (3/1) among the five Chinese isolates, 0.0094, 3.1 (3/1) between the two geographical isolate groups, and 0.0217, 4.4 (3/1) between the two facial tissue sources. Phylogenetic trees showed that D. folliculorum from the two geographical isolate groups did not form sister clades, while those from different facial tissue sources did. According to the molecular characteristics, it appears that subspecies differentiation might not have occurred and that D. folliculorum isolates from the two geographical sources are of the same population. However, population differentiation might be occurring between isolates from facial skin and eyelids.  相似文献   

Talent identification and selection process of outfield players and goalkeepers in a professional soccer club     

Susana María Gil  Jon Zabala-Lili  Iraia Bidaurrazaga-Letona  Badiola Aduna  Jose Antonio Lekue  Jordan Santos-Concejero 《Journal of sports sciences》2014,32(20):1931-1939

Abstract

The aim of this study was to analyse the talent identification process of a professional soccer club. A preselection of players (n = 64) aged 9–10 years and a final selection (n = 21) were performed by the technical staff through the observation during training sessions and matches. Also, 34 age-matched players of an open soccer camp (CampP) acted as controls. All participants underwent anthropometric, maturity and performance measurements.

Preselected outfield players (OFs) were older and leaner than CampP (P < 0.05). Besides, they performed better in velocity, agility, endurance and jump tests (P < 0.05). A discriminant analysis showed that velocity and agility were the most important parameters. Finally, selected OFs were older and displayed better agility and endurance compared to the nonselected OFs (P < 0.05). Goalkeepers (GKs) were taller and heavier and had more body fat than OFs; also, they performed worse in the physical tests (P < 0.05). Finally, selected GKs were older and taller, had a higher predicted height and advanced maturity and performed better in the handgrip (dynamometry) and jump tests (P < 0.05).

Thus, the technical staff selected OFs with a particular anthropometry and best performance, particularly agility and endurance, while GKs had a different profile. Moreover, chronological age had an important role in the whole selection process.  相似文献

Innovation and network multiplexity: R&D and the concurrent effects of two collaboration networks in an emerging economy     

Mariana Giovanna Andrade Rojas  Edgar Rogelio Ramirez Solis  John JianJun Zhu 《Research Policy》2018,47(6):1111-1124

This study focuses on the multiplexity of firm R&D networks, and it investigates two types of boundary-spanning networks: the bipartite network between firms and government-sponsored institutions (GSIs), and the traditional firm–firm network. We apply a social network perspective to examine the effects that these kinds of networks have on firm innovativeness, in relation to the effects of the firm’s internal R&D efforts. We define the firm-GSI network as bipartite, and we investigate how the structural characteristics of this network (cohesion and centrality) affect innovativeness. We then decompose the innovational effects of firm–firm networks into two categories (intra- and inter-sector) to distinguish the effects of these collaboration networks. Furthermore, we investigate how these various external collaborative networks interact with a firm’s internal R&D efforts for driving innovativeness. Our empirical study of 420 manufacturing firms in Mexico evaluates evidence from surveys and secondary data. The findings indicate that the structural properties of both firm–GSI and firm–firm networks have positive effects on innovativeness, but firm–GSI network cohesion has a stronger negative interaction with R&D in influencing firm innovativeness. Moreover, intra-sector centrality in a firm–firm network has a stronger negative interaction with R&D than inter-sector centrality does in driving firm innovativeness. We contribute to the literature by integrating insights from the perspectives of network multiplexity, social embeddedness, and resource complementarity in regard to inter-organizational behavior. Our study also provides meaningful guidelines for both managers and policy makers. The study’s findings are robust to concerns of common method bias and alternative model specifications.  相似文献
