An innovative approach to the intellectual property in haute cuisine

The paper investigates the relationship between the culinary innovation process (divided in two stages: idea generation and idea transformation) and the role of creativity protection. The aim is to understand how chefs protect their creativity and their innovation outcomes. The analysis is based on a sample of 132 Italian Michelin-starred chefs. The study sheds light on creativity and innovation domains in the hospitality environment where organizations have to continuously innovate in order to maintain a defensible competitive position. It identifies five “barriers against imitation” by competitors: “listening to clients’ needs”; “chef’s own creativity”, “systematic approach to creativity”; “knowledge based feasibility”; “accumulated professional skills”. The paper represents an initial effort to examine creativity protection concepts in the gastronomy sector, which are still unexplored. It contributes to a better understanding of how to protect the intellectual property in a sector where the applicability of law-based intellectual property systems is very low.     

The organizational evolution,systematic construction and empowerment of Langde Miao's community tourism

Tourism in the village of Langde Miao is an example of ethnic village tourism in China. Its mode of operation and organization – characterized by community guidance, public participation, and its work point system is known as the “Langde Mode”. Its success, both social and financial, provides an ideal model by which to investigate community empowerment and its role in promoting tourism. To this end, using literature reviews and empirical research, this paper evaluates the Langde Miao people's community participation in its tourism. It is suggested that the evolution of the Lande Miao community's organizational and systematic skills to develop tourism have fostered the local community's economic, social, and political success. This success can then further support community empowerment, requiring limited subsequent intervention by the government. It is suggested that the model can then be expanded to other localities throughout China.     

Is dabigatran considered a cost-effective alternative to warfarin treatment: a review of current economic evaluations worldwide

Abstract

Objective:

Dabigatran was the first of a new generation of anticoagulation drugs for the indication of non-valvular atrial fibrillation (AF) to be approved. Evidence show that dabigatran 150?mg twice daily significantly reduces the risk of stroke and systemic embolism (RR?=?0.65; p?<?0.001) and shows a comparable rate of major bleedings (RR?=?0.93; p?=?0.32), whereas dabigatran 110?mg twice daily was associated with a comparable rate of stroke and systemic embolism (RR?=?0.90; p?=?0.30) and a significantly lower rate of major bleedings compared to warfarin treatment (RR?=?0.80; p?=?0.003). The purpose is to review current economic evaluations of these alternatives for healthcare professionals to include these findings in their decision-making.

Methods:

A systematic literature search identified 43 economic evaluations, of which 10 were included and evaluated according to the Consensus Health Economic Criteria list (CHEC-list) and the Oxford model.

Results:

Six economic evaluations concluded that dabigatran was a cost-effective alternative to warfarin. One evaluation concluded the same except when quality in warfarin treatment was excellent, with a mean time in therapeutic range (TTR)?>?73%. Three evaluations concluded that dabigatran was a cost-effective alternative to warfarin in patient sub-groups; TTR?≤?64%, congestive heart failure, hypertension, age?≥?75, diabetes mellitus, prior stroke or transient ischemic attack (CHADS2 score) ≥3, or a CHADS2 score?=?2 unless international normalized ratio (INR) control was excellent, and with high risk of stroke or in a low-quality warfarin treatment. Dabigatran 110?mg twice daily was in general dominated by dabigatran 150?mg twice daily.

Limitations:

The evaluations were not fully homogeneous, as some did not include loss of productivity, costs of dyspepsia, and annual costs of dabigatran patient management.

Conclusions:

In the majority of the economic evaluations, dabigatran is a cost-effective alternative to warfarin treatment. In some evaluations dabigatran is only cost-effective in sub-groups, such as patients with a low TTR-value in warfarin treatment and a CHADS2 score ≥2.

Intra-industry transfer effects of credit risk news: Rated versus unrated rivals

We examine the information transfer effect of bond-rating adjustments on industry rivals. Our research is based on the premise that the transfer effect is influenced by the rated status of rivals, i.e., whether the rival’s debt is rated by any credit rating agency. The results reveal that credit rating adjustments induce different/stronger effects. First, the intra-industry transfer effects (on returns and risk) are stronger on rated rivals than on unrated rivals. Second, the credit risk news produces lower co-movements between the returns of the two types of rivals. Third, the differential effect is stronger in the manufacturing industry, in the riskiest industries and in the industries with the lowest competition levels. Interestingly, our results suggest that credit rating news is more relevant for rivals with access to the public debt market (such as re-rated firms) than for rivals that focus on other sources of funding.     

ASIT—a problem solving strategy for education and eco-friendly sustainable design

There is growing recognition of the role teaching and learning experiences in technology education can contribute to Education for Sustainable Development. It appears, however, that in the Technology Education classroom little or no change has been achieved to the practice of designing and problem solving strategies oriented towards sustainable design. Brainstorming, Brainwriting, SCAMPER, Metaphoric Thinking, Outrageous Thinking, Mind Mapping and other problem-solving strategies used in the classroom could be suitable for eco-design, however, there appears to be little research data on their use. This paper examines and presents the ‘Advanced Systematic Inventive Thinking’ (ASIT) system as an eco-design strategy. ASIT is derived from a more complex engineering-based problem solving strategy known as TRIZ (the Russian acronym for The Theory of the Solution of Inventive Problems). Drawing on Stable’s (in press) call for new approaches to address sustainable design and achieve solutions through Technology Education, this article traces the history of TRIZ and the development of ASIT. It then argues that the ASIT strategy can be an effective methodology to be taught and used in the Technology Education classroom to solve problems in the ‘eco’ or sustainable design context. Several design scenarios have been included to illustrate how ASIT can deliver eco-design solutions to problems. These examples demonstrate the flexibility of the methodology and the diverse range of applications in which ASIT can be applied.     

Estimating Beta-Coefficients of German Stock Data: A Non-Parametric Approach

Abstract

Although the consumption based asset pricing theory appears to be theoretically superior and more elegant than the beta pricing model, in practice the beta pricing model is more widely applied. Indeed, beta pricing models are one of the most widely adopted tools in financial analysis. They readily allow handling systematic risk as priced in financial assets. However, accurately estimating beta-coefficients is not as straightforward as implicitly suggested by Sharpe's standard market model, i.e. simply using the ordinary least-squares (OLS) regression. This is primarily because beta-coefficients cannot generally be assumed to be stable over time. In order to overcome this deficiency, we present and apply a non-parametric estimation technique that allows capturing this time effect and promises both more reliable estimates than obtained with an OLS regression as well as better manageability compared with the existing time-series approaches dealing with time-varying beta-coefficients. Estimation results for constant and time-varying betas are presented for portfolios of German industries.     

农民收入持续增长的制度性障碍及其对策研究

2005年中央一号文件的出台,极大地调动了农民的积极性,给农民增收提供了政策保障。但是,由于制约农民收入增长的根本性因素没有发生变化,农民收入增长的基础不牢靠。而制度性障碍是造成农民收入增长缓慢最重要最根本的原因。要实现农民收入的持续增长,必须以制度创新为核心,全面推进农村的政治、经济体制改革。     

Consumer innovativeness and its correlates: A propositional inventory for future research

This article summarizes the results of a systematic review of the literature on consumer innovativeness and its correlates and provides a propositional inventory for future research. The authors identified seventy-nine relevant empirical articles from international journals through a search of multiple databases using specific search terms, a manual search of marketing and consumer behavior journals and a cross-reference search. The results show that innovativeness consists of different levels of conceptualization and operational processes. Based on these different conceptualizations, the authors offer propositions for further empirical exploration on consumer innovativeness.
