居民对生态旅游认知与态度之研究--以澎湖列岛为例

本文旨在了解澎湖列岛居民生态旅游的认知与发展生态旅游的态度，并探讨居民基本资料与其对生态旅游认知和发展生态旅游态度之间的关系。经统计分析后发现：居民基本资料的不同会造成生态旅游认知与发展生态旅游态度的差异。最后透过典型相关分析发现，居民生态旅游的5个认知因素与发展生态旅游的6个态度因素间都具有相关性；居民对生态旅游的认知程度愈低者，在发展生态旅游态度上则愈不积极。     

Strategies to increase agricultural productivity and reduce land degradation: evidence from Uganda

This paper estimates a structural econometric model of household decisions regarding income strategies, participation in programs and organisations, crop choices, land management, and labour use, and their implications for agricultural production and soil erosion; based upon a survey of over 450 households and their farm plots in Uganda. Many factors have context-specific impacts and involve trade-offs between increasing production and reducing land degradation. Government agricultural extension and training programs contribute to higher value of crop production in the lowlands, but to soil erosion in the highlands. By contrast, non-governmental organization (NGO) programs focusing on agriculture and environment help to reduce erosion, but have less favourable impacts on production in the lowlands. Education increases household incomes, but also reduces crop production in the lowlands. Poverty has mixed impacts on agricultural production, depending on the nature of poverty: smaller farms obtain higher crop production per hectare, while households with fewer livestock have lower crop production. Population pressure contributes to agricultural intensification, but also to erosion in the densely populated highlands. Several household income strategies contribute to increased value of crop production, without significant impacts on soil erosion. We find little evidence of impact of access to markets, roads and credit, land tenure or title on agricultural intensification and crop production and land degradation. In general, the results imply that the strategies to increase agricultural production and reduce land degradation must be location-specific, and that there are few 'win-win' opportunities to simultaneously increase production and reduce land degradation.     

Can Fraudulent Cues Be Transmitted by Innocent Participants?

The authors explore whether and how linguistic indicators of fraud make their way into the Management Discussion & Analysis (MD&A) section of financial reports. Although research has shown that word choice and tone can help identify fraudulent financial reports, it is as yet unclear how this occurs when these reports are written by many individuals, some of whom are unaware that financial misrepresentation is occurring. Through an examination of industry recommendations and interviews with individuals experienced in writing the MD&A section, the authors confirm that many hands are involved in drafting this portion of financial reports. The authors then structure an experiment, using a real fraud case, that asks participants to write an MD&A from truthful prior U.S. Securities and Exchange Commission filings and a memo from the CFO with suggestions of what to say in the current period MD&A. Unbeknownst to participants the CFO memo was created using phrases from financial statements subsequently identified to be fraudulent. The authors find that individuals do unwittingly write MD&A associated with fraudulent financial statements with relatively little suspicion and that linguistic cues contained in the CFO memo are transmitted to the ultimate MD&A through naive and innocent participants.     

Collective Action with Incomplete Commitment: Experimental Evidence

Face-to-face communication is investigated as an efficiency-enhancing mechanism in experimental common-pool resource environments in which the appropriation activities of outside appropriators create coordination and monitoring problems for the communicating group. We identify three distinct problems that can threaten successful collective action. Outsiders respond strategically to reductions in appropriation by cooperating group members. Members of the communicating group deviate from agreements more frequently when monitoring is imperfect and over appropriation can be blamed on outsiders. Groups that are allowed to communicate anticipate the potential problems and have difficulty reaching agreements or committing to a specific appropriation rule.     

Aggregate risk sharing and equivalent financial mechanisms in an endowment economy of incomplete participation

Summary. A pure endowment overlapping generations economy can be inefficient because of insufficient risk sharing. The introduction of an outside asset by a government or the existence of a clearing house can remedy the inefficiency by allowing some intergenerational risk sharing. While the typical outside asset is fiat money, many alternative financial mechanisms, such as social security, risk-free government bonds, mispriced deposit insurance, and income insurance can serve the same function as fiat money. Hence there are many equivalent financial mechanisms that provide intergenerational insurance. In the presence of uncertainty, there are several concepts of Pareto optimality that can be appropriately applied in an overlapping generations setting. I examine the risk-sharing arrangements associated with two different concepts of optimality, including how these arrangements are financed. The results are related to, and in some instances an extension of, the equivalence results obtained by Chamley and Polemarcharkis (1984), Weiss (1977), and Wallace (1981).Received: 4 March 2003, Revised: 30 January 2004JEL Classification Numbers: E40, E44, D51.P.

世界自然遗产地游客旅游解说需求之研究——以湖南武陵源风景名胜区为例

本文以湖南武陵源世界自然遗产地为研究对象,通过游客问卷调查,以便利抽样的方式探讨游客社会经济背景因素对游客旅游解说需求(解说媒体偏好与解说主题兴趣)的影响,以指导武陵源世界自然遗产地经营管理者对未来解说规划的制定与实施.研究发现,在解说媒体选择上.游客偏好于带队解说、定点解说与咨询服务等人员解说方式,游客性别、年龄、教育程度、职业、婚姻与居住地对解说媒体的偏好有显著差异;在解说主题选择上,游客对森林、植物、动物、地质等较有兴趣,游客性别、年龄、教育程度、职业、婚姻对解说主题的兴趣也有显著的差异.     

Revisiting the research–practice gap in HR: A longitudinal analysis

Over 6300 articles published in 4 HR-focused journals over a 30-year period of time (1976–2005) were content analyzed according to 14 topic areas. The purpose of the study was to examine changes that have taken place over a 30-year time frame. Specifically, what HR issues dominate the field during the past and the present? And to what extent has the HR research–practice gap narrowed or widened over time? The results indicate that HR Development and Staffing were dominant HR issues throughout the past 30 years. In addition, some HR topics demonstrated a stable research–practice gap (Motivation-related issues), and other topics were characterized by an increasing gap (Compensation & rewards), a decreasing gap (Employee/Labor relations), or no significant gap (HR Developments, Staffing). These findings are discussed in the context of key human capital trends.
