民族旅游开发与民族文化保护理念

我国民族文化旅游的兴起，既满足了当代旅游者的需求，又促进了当地经济发展，但同时不可避免地给当地民族文化带来一定影响。民族旅游可以促进文化交流，为民族文化的传承提供动力。民族旅游的开发要走生态之路，树立文化认同观念。     

试论长江文化生态的主要特征

大自然孕育了万物,人类又在自然的基础上创造了文化。久远深厚、异彩纷呈的长江文化,正是得益于广阔的发展舞台、优越的生态环境条件。因此探讨长江文化系统与生态环境系统的耦合关系－文化生态,就具有十分重要的意义。着重论述了长江文化生态的主要特征：（1）整体性－－长江文化生态系统的各组成部分是彼此联系、相互作用的统一,它能反映整体的特征和活动方式,它孕育了长江多元文化。（2）开放性－－长江流域是一个庞大的、开放的外流水网系统,该系统不从外部输入物质、能量和信息,吸收并累积负熵流,维持其有序性。长江文化具有悠久的开放传统和宽广的心态。（3）动态性－长江文化生态系统的动态特征,既有周期性变化也有非周期性变化。（4）人地相关性－长江文化生态民是人地关系相互作用的统一体,回顾长江文化的发展史,人与自然关系经历了“强烈依赖－－被动顺序－－主动征服－－相互和谐”几个阶段。     

The relationship between employees' perceptions of safety and organizational culture

PROBLEM: With limited resources to help reduce occupational injuries, companies struggle with how to best focus these resources to achieve the greatest reduction in injuries for the optimal cost. Safety culture has been identified as a critical factor that sets the tone for importance of safety within an organization. METHOD: An employee safety perception survey was conducted, and injury data were collected over a 45-month period from a large ready-mix concrete producer located in the southwest region of the United States. RESULTS: The results of this preliminary study suggest that the reductions in injuries experienced at the company locations was strongly impacted by the positive employee perceptions on several key factors. Management's commitment to safety was the factor with the greatest positive perception by employees taking the survey. DISCUSSION: This study was set up as a pilot project and did not unitize an experimental design. That weakness reduces the strength of these findings but adds to the importance of expanding the pilot project with an appropriate experimental design. SUMMARY: Management leadership has been identified, along with several other factors, to influence employee perceptions of the safety management system. Those perceptions, in turn, appear to influence employee decisions that relate to at-risk behaviors and decisions on the job. IMPACT ON INDUSTRY: The results suggest that employee perceptions of the safety system are related to management's commitment to safety, which, in turn, appear to be related to injury rates. Management should focus on how to best leverage these key factors to more positively impact injury rates within their companies.

多效唑在重瓣丝石竹组织培养中的作用

多效唑能增加重瓣丝石竹组织培养苗的节数,缩短节间距,使试管苗健壮,其最适浓度为1．0mg/L。经多效唑（0．05ml/L-0.2ml/L)壮苗培养,显著地促进了组织培养苗生根。较高浓度的多效唑（0．20mg/L-1.0mg/L)对茎尖外植体不定芽分化有明显的增殖作用,同时抑制了试管苗玻璃化。     

The strategic gap in air-quality management

The successful management of atmospheric pollution is best achieved when the benefits of controls can be clearly demonstrated to those who the controls affect. There is a need to demonstrate to a population that change will benefit the social and biophysical aspects of that population’s environment as a whole. This paper suggests that policy-makers need to demonstrate clearly the advantages of a change in behaviour for the local environment while concurrently minimising the life-style costs of the people whose co-operation is needed to bring that change about. This requires an improved understanding of the activities affected and the message and media by which environmental benefits can be communicated in the light of that understanding.Using the example of tropospheric ozone, this paper argues that air-quality management requires close regional co-ordination which can facilitate the establishment and implementation of local policy options. The ability of the UK National Air Quality Strategy to achieve this in its present form is discussed and the existence of a strategic gap between the current approach to air-quality management and the major issues surrounding air quality considered.

MEETING PUBLIC EXPECTATIONS WITH ECOLOGICAL INNOVATION IN RIPARIAN LANDSCAPES1

ABSTRACT: Appearances matter for managing riparian landscapes because the appearance of landscapes affects public willingness to accept plans and designs that improve ecological quality. Riparian landscape design and planning should respect and strategically incorporate characteristics that the public values and expects to see. Such design can be quite novel in its ecological effects, but it also should be sufficiently familiar in appearance to correspond with cultural values. This paper describes some influential cultural values for riparian landscapes and demonstrates how attention to such values supports public acceptance of ecologically innovative design in rural and urban watersheds.
