德国的旅游教育体系概述

德国旅游专业的高等教育包括职业教育和学术教育两种,其中旅游职业教育已经相当完善,而旅游学术教育尽管50年前已经开设了第一门课程,但相当而言仍然较新.旅游学术教育目前主要由应用性课程组成,并力图理论与实践相结合.尽管德国的许多综合性大学都优先发展旅游专业,但综合性大学的旅游专业目前还没有独立的学科和学位.随着"波隆那宣言"的影响、以及本科和硕士课程在德国的引入,情况会随之变化.     

One year ahead! Investigating the time lag between patent publication and market launch: insights from a longitudinal study in the automotive industry

Technology‐oriented companies find themselves confronted with the challenge of having to react quickly to technology‐based innovations by competitors. Especially the market launches of innovative products have the ability to change the competitive environment dramatically. This calls for the ability to discern product technologies in due time. Even though several methods of technology monitoring are based on patent information, the important time lag between patent disclosure and market launch is still unclear and volatile for reasons unknown. Therefore, we have analyzed this time lag of a respective product by way of a longitudinal case study in the field of automotive engineering. The results show that in our case, patents form a valuable information source in short‐term product technology monitoring. Hence, analyzing patents in the context of product technologies and reacting to emerging products is a race against time.     

Organizational control as antidote to politics in the pursuit of strategic initiatives

In contrast to the contingency approach advanced by most prior work, we suggest a complementary perspective on organizational control and its relationship with performance. We argue that the simultaneous use of behavior and outcome control capitalizes on their respective advantages, and is therefore more effective than a sole reliance on either control type. Moreover, with organizational control seeking alignment between individual and organizational goals, the benefits of such a complementary approach may be more pronounced in a context characterized by high levels of organizational politics, or the pursuit of individual at the expense of organizational goals. Our analysis of strategic initiatives pursued by 184 European corporations provides support for both a complementary approach to organizational control and a contingency effect of organizational politics.

Natural Rights,Human Rights,and Libertarianism

The present article is devoted to developing a libertarian understanding of whether natural rights may or may not underpin human rights and, if so, how. Libertarianism is first defined in terms of the nonaggression principle (NAP), in answer to the question “What is the proper use of force?” This provides a basis for the libertarian positions on property rights, taxation, and many other issues, including human rights. Various philosophical rationales for the NAP are explored, including utilitarianism, religion, and natural rights. The basis of human rights is then examined. Every ethical tradition supports the nonaggression principle, which makes it an ideal candidate for the fundamental basis of human rights. Unfortunately, other traditions expand upon human rights by adding “positive” rights that ultimately violate the NAP. The conclusion takes up the application of libertarian principles to three issues, which could be viewed as human rights questions: discrimination, abortion, and the “trolley problem.” The last one involves taking one life to save many others.     

The Effect of Business and Financial Market Cycles on Credit Ratings: Evidence from the Last Two Decades

We analyze the effect of business and financial market cycles on credit ratings using a sample of firms from the Russell 3000 index that are rated by Standard and Poor's over the period 1986–2012. We also examine investor reaction to credit rating actions in different stages of business and financial market cycles. We document that credit rating agencies are influenced by business and financial market cycles; they assign lower credit ratings during downturns of business and financial market cycles and higher ratings during upturns. Our study is the first to find strong evidence of pro‐cyclicality in credit ratings using a long window. We also document stronger investor reaction to negative credit rating actions during downturns. Our results confirm theoretical predictions and inform regulators.     

THE MEASUREMENT OF TERMS OF TRADE EFFECTS

The change in goods and services available in a national economy brought about by the shifting of external price relationships is referred to as the terms of trade effects. This paper reviews the various methods which have been devised since the war to define and quantify such effects on the Gross National Product. The statistical annex shows that, as far as OECD countries are concerned, the differences between the various measures are not significant. Whereas the effects from terms of trade represented, on average, less than one half of one percent of the GNP of OECD countries during the 1960's the percentage has increased substantially since 1973, due most importantly to the increase in the oil price; by 1977 (on a 1970 price basis), it had reached 5 percent of GNP in Japan and up to 6 percent in Italy. On the other hand, the extreme case of Saudi Arabia where various formulas generate effects amounting to between one half and the whole of GNP, indicates that the measurement of terms of trade effects by various methods may give different results.     

AN ASSESSMENT OF THE RISK AND RETURN OF FRENCH COMMON STOCKS

In this paper the relationship is examined between the average return and the risk of a sample of 144 French common stocks which traded continuously over the decade 1969–1979. Although it was found that a negative relationship existed between average return and systematic risk, sufficient evidence could not be gathered to reject the hypothesis that the pricing of French common stocks conforms to the Capital Asset Pricing Model. The nature and implications of the observed negative risk-return trade-off are discussed.     

Rational Pricing of Adjustable Rate Mortgages

In this paper we develop a general method for valuing adjustable rate mortgages and by producing a set of simulation results, we show that our approach can be implemented. While the simulations are of interest in their own right, we view the approach itself as the major contribution of the paper.     

Public intermediate goods and distortionary taxation

In the Pigovian tradition, when public intermediate goods are financed by distortionary taxation, expenditure should not be carried so far as to equate the sum of the marginal productivities with the marginal cost. This paper shows how this rule may break down when commodity taxes are used to finance public intermediate goods.
