Modelling Quoting in Newswriting: A Framework for Studies on the Production of News     

Lauri Haapanen 《Journalism Practice》2020,14(3):374-394

ABSTRACT

The Mediated Social Communication (MSC) approach considers mass media a venue for opposing and complementary societal groups to publicly negotiate socially relevant topics. This negotiation is conducted through representatives of these groups and mediated by journalists. Inspired by the MSC approach, this paper presents an empirically grounded model that structures the mediating process through the process of quoting. By identifying the key phases of newswriting as sub-processes of quoting, the paper argues that journalists (1) decide on a topical issue to be addressed (topicalisation), (2) identify groups of people who are linked to this issue (societal localisation), (3) pick some people as representatives of these societal groups (personalisation), and (4) verbalise these people's points of view, often by means of quoting, inter alia (verbalisation). The four-phase model is then operationalised into a data collection method that facilitates access to and fosters new insights into the subtle dynamics of newswriting. Hitherto, these dynamics have often remained obscure, because the craft ethos is adopted as tacit knowledge through implicit socialisation and is therefore difficult for journalists to verbalise. The paper concludes by calling for reconsideration of journalists’ role as gatekeepers who decide which issues and voices are heard in public discourse.  相似文献   

Bayesian reasoning in avalanche terrain: a theoretical investigation     

Philip A. Ebert 《Journal of Adventure Education & Outdoor Learning》2019,19(1):84-95

In this article, I explore a Bayesian approach to avalanche decision-making. I motivate this perspective by highlighting a version of the base-rate fallacy and show that a similar pattern applies to decision-making in avalanche-terrain. I then draw out three theoretical lessons from adopting a Bayesian approach and discuss these lessons critically. Lastly, I highlight a number of challenges for avalanche educators when incorporating the Bayesian perspective in their curriculum.  相似文献   

Pupil participation in planning provision for special educational needs: teacher perspectives     

Rosalind Merrick 《Support for Learning》2020,35(1):101-118

There are legal, moral and practical reasons to involve pupils in planning provision for their special educational needs. We do not yet know how principles are implemented in practice. This study explored the views and experiences of 64 teachers with an interest in special educational needs through an online survey. Participants reported greater pupil involvement in everyday matters, less in conceptual aspects of planning. Effective strategies were based on good teacher-pupil relationships and school-wide systems for sharing pupil views. Participants gave examples of the impact of pupil participation on teacher insight, pupil motivation and material provision. 84 per cent indicated that they would like pupils to be more involved in decisions about their provision than they currently are. Barriers included the nature of children’s difficulties and practitioner attitudes. Listening to children is intrinsic to good teaching, yet pupils also benefit from a more formal role in provision planning.  相似文献

The effect of athletic expertise and trait emotional intelligence on decision-making     

Robert Vaughan  Sylvain Laborde  Christopher McConville 《European Journal of Sport Science》2019,19(2):225-233

The quality of decision and assessment of risk are key determinants of successful sport performance. Athletes differ fundamentally in their decision-making ability according to their athletic expertise level. Moreover, given the influence of emotions on decision-making, it is likely that a trait reflecting emotional functioning, trait emotional intelligence, may also influence decision-making. Therefore, the aim of this research was to investigate the respective contribution of athletic expertise and trait emotional intelligence to non-athletic decision-making. In total, 269 participants aged between 18 and 26 years with a range of athletic experience i.e. none (n?=?71), novice (n?=?54), amateur (n?=?55), elite (n?=?45) and super-elite (n?=?44), completed the Emotional Intelligence Scale and the Cambridge Gambling Task. Regression modelling indicated a significant positive relationship of athletic expertise and trait emotional intelligence with the quality of decision-making, and a negative relationship with deliberation time and risk-taking. Cognitive skills transfer may explain the higher decision-making scores associated with higher athletic expertise, while individuals with higher trait emotional intelligence may anticipate better the emotional consequences linked with a gambling task, which may help individuals make better decisions and take less risks.  相似文献

Understanding the topic evolution of scientific literatures like an evolving city: Using Google Word2Vec model and spatial autocorrelation analysis     

Kai Hu  Qing Luo  Kunlun Qi  Siluo Yang  Jin Mao  Xiaokang Fu  Jie Zheng  Huayi Wu  Ya Guo  Qibing Zhu 《Information processing & management》2019,56(4):1185-1203

Topic evolution has been described by many approaches from a macro level to a detail level, by extracting topic dynamics from text in literature and other media types. However, why the evolution happens is less studied. In this paper, we focus on whether and how the keyword semantics can invoke or affect the topic evolution. We assume that the semantic relatedness among the keywords can affect topic popularity during literature surveying and citing process, thus invoking evolution. However, the assumption is needed to be confirmed in an approach that fully considers the semantic interactions among topics. Traditional topic evolution analyses in scientometric domains cannot provide such support because of using limited semantic meanings. To address this problem, we apply the Google Word2Vec, a deep learning language model, to enhance the keywords with more complete semantic information. We further develop the semantic space as an urban geographic space. We analyze the topic evolution geographically using the measures of spatial autocorrelation, as if keywords are the changing lands in an evolving city. The keyword citations (keyword citation counts one when the paper containing this keyword obtains a citation) are used as an indicator of keyword popularity. Using the bibliographical datasets of the geographical natural hazard field, experimental results demonstrate that in some local areas, the popularity of keywords is affecting that of the surrounding keywords. However, there are no significant impacts on the evolution of all keywords. The spatial autocorrelation analysis identifies the interaction patterns (including High-High leading, High-Low suppressing) among the keywords in local areas. This approach can be regarded as an analyzing framework borrowed from geospatial modeling. Moreover, the prediction results in local areas are demonstrated to be more accurate if considering the spatial autocorrelations.  相似文献

史兵  丁建岚  钱钧  杨小帆  万丙智 《北京体育大学学报》2019,42(2):36-45

摘要：群众体育是我国体育事业的重要组成部分，经多年发展，逐步形成了“政府主导、部门协同、全社会共同参与”的发展模式。随着市场经济改革进一步深化，我国社会主要矛盾转化为人民日益增长的美好生活需要和不平衡不充分的发展之间的矛盾，现有群众体育发展模式已无法满足人民对健康生活的追求，迫切需要在国家治理体系层面上对其进行改革完善。通过文献资料分析法，对群众体育发展模式的结构进行剖析，对未能明确的主要问题进行梳理，发现现有模式存在主体不明、承担者模糊、发展方式单一，体育社会组织参与不够等问题。由此，提出群众体育发展模式的新思路及结构模型，明确政府、社会组织、市场在群众体育发展模式当中各自的作用、发展主体及性质。群众体育“政府引导、社会参与、公民主体、市场推动”的发展新模式将成为新时代体育事业发展的源动力。暨人民中心和公民主体地位充分体现，政府引导方式和责权范围明晰，体育社会组织参与主办承办者身份明确，社会自我组织有效管理，市场参与度高，体育服务供给丰富。以期对我国群众体育的长效发展提供建议及切实有效的发展路径，深入落实全民健身战略，提高人民健康水平。  相似文献   

Boosting question answering over knowledge graph with reward integration and policy evaluation under weak supervision     

《Information processing & management》2023,60(2):103242

Among existing knowledge graph based question answering (KGQA) methods, relation supervision methods require labeled intermediate relations for stepwise reasoning. To avoid this enormous cost of labeling on large-scale knowledge graphs, weak supervision methods, which use only the answer entity to evaluate rewards as supervision, have been introduced. However, lacking intermediate supervision raises the issue of sparse rewards, which may result in two types of incorrect reasoning path: (1) incorrectly reasoned relations, even when the final answer entity may be correct; (2) correctly reasoned relations in a wrong order, which leads to an incorrect answer entity. To address these issues, this paper considers the multi-hop KGQA task as a Markov decision process, and proposes a model based on Reward Integration and Policy Evaluation (RIPE). In this model, an integrated reward function is designed to evaluate the reasoning process by leveraging both terminal and instant rewards. The intermediate supervision for each single reasoning hop is constructed with regard to both the fitness of the taken action and the evaluation of the unreasoned information remained in the updated question embeddings. In addition, to lead the agent to the answer entity along the correct reasoning path, an evaluation network is designed to evaluate the taken action in each hop. Extensive ablation studies and comparative experiments are conducted on four KGQA benchmark datasets. The results demonstrate that the proposed model outperforms the state-of-the-art approaches in terms of answering accuracy.  相似文献
