本研究选取宁波本土饭店K和外资饭店H作为研究对象,采用问卷方法构建饭店员工满意度指标,以员工满意度作为衡量饭店软实力的切入点,将本土饭店K与外资饭店H的软实力进行了定量化的比较研究。研究表明,尽管本土饭店K的员工满意度高于外资饭店H,但在员工素质和长期发展等方面仍存在较大差距。本文还对员工学历、工资、职位等与员工满意度的关系进行了讨论。  相似文献

20多年来,旅游管理课程体系建设取得很大成绩,但依然存在课程老化固化、缺乏对社会需求响应能力等问题。通过往届毕业生、网络、新业态和旅游组织机构等多端口的职业需求信息的监测与评估,在理论和技术上可以构建一个既能响应社会需求,又能满足学生个人兴趣,还能符合国家专业要求的“三位一体”的响应社会需求的旅游动态课程体系。通过该课程体系的建设可以加强现有专业对社会需求的响应能力,减少一些短周期新专业的应急性增设,从而节约教育资源、积累教育资本、避免学生同业竞争、缓解就业压力。基于以上理论和实证研究,云南民族大学旅游管理专业未来至少可以增设美食与营养、旅游技术与工程两门课程以响应社会需求,并形成其核心竞争能力.  相似文献

清末民初地方社会整合格局的变化   总被引:3,自引:0,他引:3  
晚清以降,在内忧外患交侵之下,乡族自治传统下的地方社会秩序陷入困境。随着国家扩张权力需要的增强和地方资产阶级化新兴士绅的倔起,一种以国家与新型地方精英的合作为基础的新的地方权力格局呼之欲出。当然,由于传统势力的牵制以及国家权力与地方精英权力之间的张力,清末民初的地方权力重建过程充满了复杂的纠葛与冲突。  相似文献

The formation of gas hydrates in marine sediments changes their physical properties and hence influences fluid flow. Here, we review seismic indicators of gas hydrates and relate these indicators to gas hydrate formation and fluid migration. Analyses of seismic data from sediments containing gas and gas hydrates in a variety of locations have shown that the characteristic bottom‐simulating reflector (BSR), which commonly marks the hydrate phase boundary is caused mainly by the presence of gas beneath the gas hydrate stability zone (GHSZ). The amplitude of the BSR is also dependent on the hydrate concentration and on the porosity of the sediment. The presence of gas hydrate alters the elastic properties of sediments, particularly if it cements sediment grains. However, multifrequency studies in various geological provinces show that any loss of reflectivity or blanking observed within the GHSZ is dependent on both the nature of the sediments and concentration of hydrate present. Gas beneath the BSR may cause amplitude anomalies and may result in bright spots and enhanced reflections. The presence of gas beneath the BSR is the primary cause of observed amplitude versus offset (AVO) anomalies, but the amplitude of these anomalies is also dependent on the amount of cementation brought by the gas hydrates within the GHSZ. Fluid migration appears to play an important role in the formation and dissociation of gas hydrates in both active and passive margin settings. Fluid migration in accretionary prisms influences hydrate accumulation and may therefore control the spatial distribution of BSRs. Fluid migration may influence also the type of hydrate formed by bringing thermogenic gas containing higher order hydrocarbons to the GHSZ from below. Fluid advection may cause local dissociation of gas hydrates by bringing heat from below, thus shifting the gas hydrate phase boundary. Fluid flow within the GHSZ is limited by the formation of hydrate in the pore space, which reduces the permeability of the sediment. Features such as pockmarks, acoustic masking and acoustic turbidity are indirect indicators of fluid flow and identification of these features in seismic sections within and beneath the GHSZ may also suggest the formation of gas hydrate.  相似文献

The diffusion literature is replete with examples of highly salient policies spreading across subnational governments. However, low-salience policies that do not benefit from a groundswell of public opinion also spread across jurisdictions in patterns that appear similar to those of other, more well-known policy ideas. This research is an investigation of the mechanisms that propagate low-salience policies. I analyze the adoption of the U.S. Green Building Council's (USGBC) Leadership in Energy Efficient Design standard across 119 U.S. cities from 2000 to 2008. The investigation indicates that a knowledge broker, in this case the USGBC, occupies critical roles in linking a low-salience policy to a broader set of widely held societal values, developing a common policy vocabulary, providing a base policy that jurisdictions may freely adapt, and creating a diffusion infrastructure by acting as a communication hub for existing and interested jurisdictions to discuss innovations and progress.  相似文献

岩画意义的解释经常会出现望图生义或者恣意猜度的现象,导致学术界对岩画的解释产生了偏见。为了避免这种情况,在解读岩画的时候应当充分考虑各种可能的因素,如岩画所处的环境,岩画自身之间的关联,岩画产生地所呈现出来的地方性知识,其他学科的支持等。  相似文献

<正>在20世纪60年代前期进行的经济调整过程中,中国共产党和政府采取了许多特殊而有效的措施,完成了国民经济调整的任务,度过了困难时期。在调整后期,中国试图在经济管理体制上找出一条新路,改变统得过多过死的局面。为了照顾特殊地区的发展,1965年先后设置了安达特区和攀枝花特区,成为这个时期计划工作中的亮点。一、开发大庆油田与设立安达特区  相似文献

晚清吏治腐败。1875至1884年的10年间,曾出现过一个言官清议的高潮。当时言官奏折中披露的吏治问题,主要涉及捐纳、保举、科举、冗员、书吏、讼案、属员、调员、弄权等。捐纳、保举、科举都关系到官的任用,冗员也是这三者带来的一个官场病。书吏、讼案反映出吏的违法行为。属员、调员、弄权反映出官的腐败劣迹。  相似文献

This paper explores the perceptions of drought by residents in outback South Australia and their associated responses to the drought. Behavioural Geography methodology is used with data drawn from interviews with pastoralists, business owners, and residents of small outback towns and Aboriginal communities. Although they were not resident in the region, the perceptions of tourists were also garnered. The results show that perceptions varied between the groups of people interviewed. Outback residents contrasted their own frugal water use with reports of wasteful behaviour by foreign tourists. Local inhabitants were largely ‘accepting’ of the drought, having survived worse droughts in the past and over many years. They were therefore of the sentiment that they would cope with future droughts. Despite the sentiments of acceptance, the dropping groundwater levels and continued lack of rainfall were leading to growing concerns for the future. The concerns point to a boundary to community resilience to drought in outback South Australia.  相似文献
