重大体育赛事对城市经济发展的影响--基于中国70个大中城市面板数据分析     

毛丰付  郑芳  朱书琦 《上海体育学院学报》2020,(5):24-36

重大体育赛事的举办在一定程度上能推动承办城市转型发展,但也可能对当地经济产生某种不良影响,这主要源于对重大体育赛事与城市经济发展的内在规律和作用机制认识不够清晰。以2000-2017年22项具有全国影响力的重大体育赛事为基础,利用中国70个大中城市面板数据,采用双重差分法,分析重大体育赛事对城市经济发展的影响。发现:全样本数据下重大体育赛事的举办会促进城市第一产业向第二、第三产业发展;对比国内和国际赛事,重大体育赛事对第三产业的促进作用均显著高于第二产业;以1 085家上市公司数据为样本,采用事件研究法进行分析,发现不同行业利用重大体育赛事的窗口期存在显著差异。  相似文献   

Genetic Polymorphism of Angiotensin II Type 1 Receptors and Their Effect on the Clinical Outcome of Captopril Treatment in Arab Iraqi Patients with Acute Coronary Syndrome (Mid Euphrates)     

Fadhaa A. Ghafil  Bassim I. Mohammad  Hussain S. Al-Janabi  Najah R. Hadi  Hayder A. Al-Aubaidy 《Indian journal of clinical biochemistry : IJCB》2021,36(1):81

Genetic variation in the angiotensin II type 1 receptor (AT1R) has an important effect on the outcome of acute coronary syndrome (ACS) initiated treatment with captopril. This study aims to investigate the impact of genetic polymorphism of AT1R (rs5186 and rs275651) on the ACS outcome in Iraqi patients treated with captopril. A total of 250 Iraqi individuals with ACS were included in this case—control study and they were divided into two study groups; Study group 1 included 125 participants who were prescribed captopril, 25 mg twice daily and study group 2 included 125 participants who received no captopril as part of their ACS treatment (control study). The AT1R gene (rs5186) CC genotype was found to be associated with ST-elevation myocardial infarction (STEMI) (Odd’s ratio (O.R) = 1.2, P = 0.7), while AC was associated with Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) (O.R = 1.2, P = 0.8). AC genotype is more prone to have Percutaneous coronary intervention (PCI) after ACS attack (O.R = 1.2, P = 0.6). CC genotype had a risk to get less improvement (O.R = 1.6, P = 0.5), so might require higher doses of captopril during acute coronary insult. The AT1R gene (rs275651) AA genotype was associated with UA (O.R = 1.3, P = 0.9). AA and AT genotypes were more prone to have PCI after ACS attack (O.R = 3.9 P = 0.2, O.R = 3.5, P = 0.3 respectively) and thus requiring higher doses of captopril. We conclude that the AT1R rs5186, rs275651 genetic polymorphisms might partially affect the clinical outcome of ACS patients treated with captopril and might have captopril resistance which requires higher doses.  相似文献   

Exploring the Fluctuations of Foreign Language Enjoyment in Conversation: An Idiodynamic Perspective     

Majid Elahi Shirvan  Nahid Talebzadeh 《Journal of Intercultural Communication Research》2018,47(1):21-37

The main focus of this study was to discern the effect of different topics on the dynamics of one of the main variables of positive psychology, foreign language enjoyment (FLE). To do this, we used an idiodynamic method to explore the rapid moment-to-moment changes of FLE. Seven female university students engaged in a conversation involving both simple and difficult topics, and self-rated their moments of experiencing enjoyment during the conversation process. The results indicate that the dynamicity of enjoyment emerges not only within individuals, but also across individuals intra-personally under the influence of conversational topics. Furthermore, the idiodynamic method provided us with the opportunity to examine the underlying factors of the dynamic fluctuations of FLE and gain a deeper insight into FLE as a dynamic system.  相似文献   

图书馆情报学主要研究方法:了解、选择及使用

Paternal support for child sexual abuse victims: A qualitative study     

《Child abuse & neglect》2019

BackgroundThe current state of knowledge regarding the role of non-offending fathers in supporting their sexually abused children is very scarce.ObjectiveThe objective of this study is to further our understanding of fathers’ roles following disclosure of their children’s sexual abuse (SA) by evaluating fathers’ perceptions of the impact of disclosure on their involvement and support of their children.Participants and methodThis qualitative study relies on individual semi-structured interviews conducted with 17 fathers of allegedly abused children.ResultsInductive thematic analysis first highlighted that some reported a period of disengagement from the child during which they put into question their role and attitudes, followed by a period of re-involvement. This period of difficulties experienced by some fathers in regard to their involvement towards their children was due to either their own important psychological distress, their ambivalence towards their child or even because of feelings of uneasiness experienced during physical contact with them. Despite this, findings indicate the presence of thoughts and attitudes that suggest children are a source of concern for fathers. The four forms of abuse-specific support previously observed among mothers (believing the child, seeking out professional services, protecting him/her from the offender, supporting him/her emotionally) were also observed among fathers. In accordance with the activation theory, a form of support specific to fathers, namely, encouraging the child to open up to and explore the world outside the family, thereby, fostering the child’s self-esteem development, was observed and constitutes a relevant finding.ConclusionClinical and empirical implications are discussed.  相似文献   

Negotiating the cultural and economic outcomes of sport heritage attractions: the case of the National Baseball Hall of Fame     

Gregory Ramshaw  Sean Gammon  Felipe Tobar 《Journal of Sport Tourism》2019,23(2-3):79-95

ABSTRACT

Contemporary museums must balance their roles as commercial entities and repositories of various, and often dissonant, heritages and histories. Sports museums in particular often have clear commercial and nostalgic aims, particularly through tourist visitation, though the extent to which they represent more challenging narratives remains unclear. This paper examines how one of the most famous sports museums in the world, the National Baseball Hall of Fame (NBHF) in Cooperstown, New York, balances its dual role as tourist attraction and repository of baseball's sometimes checkered past. It was found that different sections of the museum provide greater or lesser degrees of engagement with more controversial issues, although the commercial outputs and appeal of the museum remains clear throughout. Utlimately, the NBHF demonstrates that balancing veneration and critique in collections can be commercially prosperous, and can provide a template for other sport and popular culture museums who may be wary of incorporating more challenging narratives in their exhibits. Furthermore, the symbiotic relationship between the Hall of Fame and the village of Cooperstown, particularly in creating and maintaining cultural and economic outputs, requires further exploration.  相似文献

苏鹏  苏成  潘云涛 《图书情报工作》2019,63(20):129-138

[目的/意义]颠覆性技术能变革传统生产模式和消费结构，使产业格局巨变。识别潜在颠覆性技术有助于抢占科技制高点，在科技竞争中取得先发优势。[方法/过程]通过主题检索和引文回溯搜集文献，梳理颠覆性技术现阶段的主要识别方法。[结果/结论]发现方法的选择与研究人员学科背景密切相关，根据研究人员的主要研究领域，将其划分为图书情报、工程管理、经济研究和Christansen流派4类识别方法。在此基础上对识别方法进行7个维度的比较，指出现有方法存在3个问题：过度依赖专家评价、识别标准针对性不足和超前识别效果不佳，其中识别标准针对性不足是核心问题。鉴于此，在后续研究中应当从多种角度不断探究和完善技术颠覆潜力的评价方法。  相似文献   

Local word vectors guiding keyphrase extraction     

Eirini Papagiannopoulou  Grigorios Tsoumakas 《Information processing & management》2018,54(6):888-902

Automated keyphrase extraction is a fundamental textual information processing task concerned with the selection of representative phrases from a document that summarize its content. This work presents a novel unsupervised method for keyphrase extraction, whose main innovation is the use of local word embeddings (in particular GloVe vectors), i.e., embeddings trained from the single document under consideration. We argue that such local representation of words and keyphrases are able to accurately capture their semantics in the context of the document they are part of, and therefore can help in improving keyphrase extraction quality. Empirical results offer evidence that indeed local representations lead to better keyphrase extraction results compared to both embeddings trained on very large third corpora or larger corpora consisting of several documents of the same scientific field and to other state-of-the-art unsupervised keyphrase extraction methods.  相似文献
