Based on a longitudinal case study of China's high-speed rail embedded in the emerging economy context, we focus on what role the government plays and how that matters to open innovation (OI) for competitive advantage. By linking the OI literature with the national political institutions literature to motivate our research question, we propose a statist-based OI view to differentiate diverse government roles, investigating how government adopts roles in a combined way to push OI in stages. Our findings suggest that government is an important strategic decision-maker for OI. Specifically, the government plays various roles as commander, protector, cultivator, and intermediator, reflecting state activism derived from national political institutions, to construct institutional-level OI for domestic OI activities, and inbound and outbound OI across national borders. We find government can deliberately and strategically use its diverse roles in a combined way to push OI for competitive advantage through the industrial evolutionary process over time. Our study contributes to the OI literature and integrates the strategic management literature with the study of OI to provide new insights to explain the origins of competitive advantage from the state perspective.  相似文献

The goal of this study is to provide a cross-lagged examination of the relationships between engaging leadership, job resources and employee work engagement. We propose a mediation model and we postulate that engaging leadership can increase perceptions of three specific job resources (i.e. autonomy, support from colleagues and opportunities for learning and development) which theoretically correspond to the three facets of engaging leadership (i.e., inspiring, connecting and strengthening, respectively). Subsequently, in keeping with the extant body of Job Demands-Resources (JD-R) research, we link job resources to employee work engagement. Our hypotheses were tested on data collected at two time-points – T1 (N = 759) and T2 (N = 273) –from employees working for a hotel chain in the Netherlands. In line with our expectations, engaging leadership showed a significant cross-lagged relationship with autonomy and support from colleagues, but did not predict learning opportunities and work engagement across time. While we formulated specific hypotheses, we also tested reversed causation relationships. We found no direct effect from engaging leadership on employee work engagement, however, the reversed effect was significant; employee perceptions of engaging leadership were shaped by their own engagement experiences. Importantly, engaged employees at T1 reported more job resources at T2. By providing a cross-lagged examination of our model, we showed that engaging leaders as well as employees’ positive affective state of being engaged, are essential to shaping a resourceful work context. A comprehensive view on the triggers and outcomes of work engagement and engaging leadership is needed, as the traditional unidirectional cause-effect rationale fails to explain how these concepts relate to one another and to employee experiences of job resources.  相似文献

普里什文哲理散文中所具有的预言式生态思想与环保理念备受当代“生态文学”理论家的青睐。但他热衷描写狩猎场景的猎人情结却又遭到新世纪中“生态伦理”理论的诟病。其实从文本的本体性观念来理解,普里什文的诗性自然情怀、生态观念与他的猎人情结并非只有冲突的一面,他所表达出的是人对大自然万物之本能与道义之间的尺度衡量,而这种衡量也可反观当代人与自然万物之间的关系的现状,实际上表达出一种更为深刻的天人关系的批判性。  相似文献

通过对5位国家级教学名师的自述报告进行三级编码和主题凝练,研究发现国家级教学名师作为教师队伍的杰出代表,在其专业发展过程中养成了许多优秀品质。例如:教学方面注重实践、考虑周全,师德方面以德施教、追求卓越,科研方面以教带研、实现创新。国家级教学名师优秀品质的养成通常经历了漫长而曲折的过程,不仅需要精神与物质力量的共同推动,还需要家庭、学校和社会各环境要素的相互促进,以及社会取向养成方式和个人取向养成方式的互相配合。深入探究国家级教学名师的优秀品质及其养成之道,可以为教师专业发展提供借鉴与启示。  相似文献

四川盆地卤水分布广泛,资源丰富, 早为世人所瞩目,中三叠统雷口坡组是四川盆地最早开采天然气和盐卤的层系之一。根据盆地雷口坡组大量钻井资料研究表明,盆地雷口坡组主要成盐期分别为雷三2 期和雷四2 期,在盆地东部和南部由于受到古隆起的影响,盐岩地层已被剥蚀难以保存,现今盐岩主要分布在开江古隆起和泸州古隆起的西部以及天井山古隆起的南部(华蓥山以西—龙门山以东的川西—川中地区)。印支运动对盆地雷口坡组盐岩在平面的迁移起着十分重要的作用,根据不同时期盐岩统计数据看,两期盐盆在平面上具有向西迁移、叠加的特征,其中川中的GS1 井就钻遇了这两期的盐岩。  相似文献

ProblemIn countries where education programmes are assessed as meeting international standards there is limited knowledge about the challenges facing midwifery education.Background/aimThe positive impact of quality midwifery education on maternal and newborn health is acknowledged by the World Health Organisation. However, there is limited research identifying the issues faced in providing quality midwifery education. The aim of this study was to identify the challenges and determine priority projects to strengthen midwifery education across Australia and New Zealand.MethodsA two-round Delphi study with experts in midwifery education was undertaken.FindingsIn round one, 85 participants identified an initial 366 issues for midwifery education. Through thematic content analysis these were categorised into 89 statements reflecting five major themes: In round two, 105 midwifery experts from Australia n = 86 (79%) and New Zealand n = 23 (21%) rated the 89 statements in order of priority. Across the combined data (Australia and New Zealand) a total of 19 statements gained consensus of ≥80%.DiscussionFive priority themes were identified including; (1) enabling success of First Peoples/Māori midwifery students; (2) increasing the visibility and influence of midwifery within regulation, accreditation and university governance; (3) determining how best to deliver the clinical practicum component of programmes; (4) reviewing midwifery programmes to enhance design, content and delivery; and (5) ongoing education and support for the midwifery workforce.ConclusionIn Australia and New Zealand, it is imperative that collaborative work is undertaken to design and action identified projects addressing these priorities.  相似文献

运用传播学内容分析法,以中央媒体对获得"全国教书育人楷模"和"最美教师"荣誉称号的"国家教师"相关报道为研究对象,从外在和内在两个方面对大众传播的"国家教师"媒介形象进行分析。外在形象包括教师性别、年龄、教龄、外表、场景以及任教的学校类别、区域、学科专业等方面,内在形象包括职业精神、职业知识和职业能力等方面。研究发现,大众媒体对"国家教师"形象的刻画和宣传符合社会公众认知教师职业的基本逻辑,起到了传递教师精神、端正教师形象、唤起社会尊重教师的功效,但也存在城乡教师形象传播刻板化以及教师普通人形象展现不充分等问题,可在后续的传播中对"国家教师"形象的价值倾向进行适当调整。  相似文献

2018 marks the 50th anniversary of Enoch Powell’s infamous ‘Rivers of Blood’ speech, an intervention that is still viewed as one of the most incendiary statements of the perceived decay and violence likely to follow legislation intended to assure minoritised British citizens of equal rights regardless of their ethnic origin. In this essay, Sally Tomlinson (one of Britain’s foremost multicultural theorists) reflects on Powell’s legacy and the contemporary scene where in the US, UK and across Europe, White resentment and fear is increasingly shaping ‘mainstream’ debates about nationhood, migration and education.  相似文献

As important members of research teams, statisticians bear an ethical responsibility to analyze, interpret, and report data honestly and objectively. One way of reinforcing ethical responsibilities is through required courses covering a variety of ethics-related topics at the graduate level. We assessed ethics requirements for graduate-level statistics training programs in the United States for the 2013–2014 academic year using the websites of 88 universities, examining 103 biostatistics programs, and 136 statistics degree programs. We categorized programs’ ethics training requirements as required or not required. Thirty-one (35.1%) universities required an ethics course for at least some degree students. Sixty-two (25.5%) degree programs required an ethics course for at least some students. The majority (77.4%) of required courses were worth 0 or 1 credit. Of the 177 programs without an ethics requirement, 19 (10.7%) listed an ethics elective. Although a single ethics course is insufficient for instilling an ethical approach to science, degree programs that model expectations through coursework point to the value of ethics in science. More training programs should prepare statisticians to consider the ethical dimensions of their work through required coursework.
