Forest management poses particular challenges as the pressure on forests is huge due to deforestation. In this context, the establishment of protected areas is a common conservation measure where institutions are put in place and sanctions regarding forest use are enforced. This paper focuses on the practice of sustainable forest management and the associated perspectives of local institutions at the rainforest margins of Lore Lindu National Park (LLNP) in Central Sulawesi, Indonesia.  相似文献

This study explores the properties and development of the matching technology in the Czech Republic during the transition to a market economy. Nonparametric additive modelling allows us to assess flexible functional forms, which comprise for instance CES and trans-log specifications. This enables us to evaluate the matching process locally for each combination of unemployment and vacancies rather than being restricted to global coefficients. Special interest is devoted to analysis and economic determinants of regional variation in the returns to scale of the matching function. Non-linearities are found in the partial adjustment process of unemployment outflows, and a negative coefficient on vacancies in some years. Moreover, increasing returns to scale in job-matching are found locally. Returns to scale are found to be negatively correlated to the share in employment in services and to outmigration, positively correlated to the employment share in industry, the unemployment rate and various measures of active labour market policies.  相似文献

E-mobility technology is commonly expected to fully meet future mobility demands. However, during the next two or three decades, the number of vehicles powered by an internal combustion engine (ICE) will not only remain high but will probably increase in absolute numbers. Oil as the dominant energy source for transportation purposes is limited, and it is expected that e-mobility will not be able to substitute the demand for ICE vehicles. Renewable liquid energy sources will be needed to ensure future mobility.  相似文献

This article addresses the problem of human error within a technical environment. A model of a human-machine interface is presented to illustrate the work situation in an open perspective. The term human error is defined and briefly discussed. A general framework for controlling human error is presented with proactive and reactive approaches. Some well-known methods of human reliability assessment are discussed and the general limitations of the methods are elaborated. The reactive approaches are compared with proactive approaches, and the term 'safety culture' is elucidated. The importance of high reliability organizations to serve as model companies for other organizations is briefly discussed.  相似文献

The article examines the network dynamics from franchising to licensing due to the increase of contractibility of the franchiser's system-specific assets as determinant of the allocation of decision rights between the network partners. Based on the property rights approach, residual decision rights must be allocated according to the distribution of intangible knowledge assets between the franchiser and franchisee. Our analysis derives the following hypothesis: The more contractible the franchiser's system-specific assets, the higher is the tendency from franchising toward licensing. In addition, we investigate the impact of strategy change on the standardization (contractibility) of system-specific assets and the network governance. We argue that a change of strategy may increase the contractibility of system-specific know-how and consequently the tendency toward licensing. This study presents empirical evidence from company Getifix on the network dynamics from franchising to licensing.  相似文献

The European Central Bank (ECB) recently announced its willingness to do whatever is needed to save the euro. This has raised the question whether such a role of the ECB must lead to higher rates of infl ation. Under current recessive macroeconomic conditions in the eurozone, the ECB’s expansionary monetary policy will not lead to higher infl ation. On the contrary, there is a serious danger of defl ation. Higher infl ation would likely occur only if a permanent stabilisation function were assigned to the ECB. Yet historical examples show that mistakes can be made. During the stagnation in Japan, US economists heavily criticised the Bank of Japan’s timid monetary policy response. But in some sense, current Fed policy seems to be a direct copy of that strategy, caused by uncertainty about the proper communication channel. An infl ation tax could help to bring down the mounting public debt in the wake of the fi nancial crisis, but higher wealth taxes have more transparent distributional effects.  相似文献

Using American panel data from the National Education Longitudinal Study of 1988, this article investigates the effect of working during grade 12 on attainment. We employ, for the first time in the related literature, a semiparametric propensity score matching approach combined with difference‐in‐differences. We address selection on both observables and unobservables associated with part‐time work decisions, without the need for instrumental variable. Once such factors are controlled for, little to no effects on reading and math scores are found. Overall, our results therefore suggest a negligible academic cost from part‐time working by the end of high school.  相似文献
