This paper builds on an agreement coefficient proposed by Krippendorff (Content analysis: an introduction to its methodology, 2013) for measuring the reliability of unitizing and coding continuous phenomena, for example, of texts, videos, or sound recordings. It serves three purposes: It modifies Krippendorff’s definition which turned out to behave not as expected when applied to more than two observers, coders, or annotators. It extends this reliability measure to a family of four coefficients able to assess the reliabilities of diverse properties of unitized continua. It adds a way to obtain the confidence intervals of these coefficients as well as the probability of failing to reach targeted reliability levels. And it describes and provides access to free software that calculates all values of this family of reliability coefficients. 相似文献
While prior research has indicated the importance of conflicts between investors and entrepreneurs, little is known about their causes. We use theory on entrepreneurial decision-making to examine the impact of a founding team’s causal versus effectual decision style on the level of perceived task conflict that founders experience with their venture capitalists. Based on a sample of 141 German ventures, we find that a founding team perceives fewer conflicts when following the causal principle of overcoming the unexpected and the effectual principle of affordable loss. 相似文献
The purpose of this article is to investigate the socio-economic as well as the political, institutional, and ideological causes of the Chinese famine of 1959–1961. The main hypothesis of this paper is that the radical policies implemented as part of the Great Leap Forward resulted in agricultural output decline (i.e., availability issues), and in the implementation of an ineffective food distribution policy affecting rural populations (i.e., accessibility issues). An econometric analysis, based on provincial panel data from the 1954–1966 period, stresses the effect of ill-advised economic policies in handling the famine. This analysis also confirms that the increase in mortality rates during the famine was caused by the simultaneous collapse in food availability and food accessibility in rural areas. 相似文献
In spite of its use to explain market processes, neoclassical economics still has not integrated entrepreneurship into its analyses. This explanatory gap is the consequence of the analytical closed-endedness of the “market” processes described by the neoclassical framework, where social interactions do not result in new unpredictable information. However, entrepreneurship as profit-seeking under uncertainty is an open-ended process characterized by a creatively reflexive and emergent interactive behavior in society. This open-endedness involves the generation of novel, complex, and extensive future information that is not what anyone intended it to be. Neoclassical economics, with its predetermined assumptions on economic behavior, cannot really account for the fundamental uncertainty of open-ended processes because it cannot explain reflexivity or emergence. Therefore, it cannot explain entrepreneurship as either an innovatively cohesive or disruptive behavior that converges toward future market situations. 相似文献
Aims: To estimate the cost-effectiveness of a new strategy that uses an amino acid formula in the elimination diet of infants with suspected cow’s milk allergy (CMA).
Materials and methods: This pharmacoeconomic study was developed from the perspective of the Brazilian Public Healthcare System. The new strategy proposes using an amino acid formula in the diagnostic elimination diet of infants (≤24 months) with suspected CMA. The rationale is that infants who do not respond to the amino acid formula do not suffer from CMA. Patients with a positive oral challenge test receive a therapeutic elimination diet based on Brazilian Food Allergy Guidelines. This approach was compared to the current recommendations of the Brazilian Food Allergy Guidelines. A decision model was constructed using TreeAge Pro 2012 software. Model inputs were based on a literature review and the opinions of a panel of experts. A univariate sensitivity analysis of incremental cost-effectiveness ratios was performed.
Results: The mean cost per patient of the new amino acid formula strategy was R$3,341.57, while the cost of the current Brazilian guidelines strategy was R$3,641.08. The mean number of symptom-free days per patient, which was used as an indicator of effectiveness, was 900.6 and 875.7 days, respectively. The new strategy is, therefore, dominant. In the sensitivity analysis, the dominance was maintained with parameter variation.
Limitations: In the absence of information in the literature, some premises were defined by a panel of specialists.
Conclusions: The new strategy, which uses an amino acid formula in the elimination diagnostic diet followed by an oral food challenge, is a dominant pharmacoeconomic approach that has a lower cost and results in an increased number of symptom-free days. 相似文献
This paper discusses the role of the Clean Development Mechanism (CDM) in the market for carbon quotas and countries' commitments to reduce their carbon emission levels. We show that the CDM contributes to an efficient funding of clean technology investments in least developed countries. However, the CDM is not neutral on the global level of carbon emissions as it entices countries to raise their emission caps. The CDM may also make inappropriate the inclusion of any country that takes no emission abatement commitment. It can even make inefficient a country's decision to commit to an emission target. The implications of the presence of non‐additional projects are also analyzed. 相似文献
Microfinance institutions (MFIs) lend to the poor. However, microfinance clients suffer from high interest rates, a type of poverty penalty. This article analyses the margin determinants in MFIs. A banking model has been adapted to microfinance. This model has been tested using 9-year panel data. Some factors explaining bank margin also explain MFI margin, with operating costs being the most important factor. Specific microfinance factors are donations and legal status, as regulated MFIs can collect deposits. It has also been found that MFIs operating in countries with a high level of financial inclusion have low margins. 相似文献
In this article, we revisit medium- to long-run real exchange rate determination within the euro area, focusing on the role of external debt. Accordingly, we rely on the NATural Real EXchange rate (NATREX) approach which provides an explicit framework of the external debt–real exchange rates nexus. In particular, given the indebtedness levels reached by the euro area economies, we investigate potential nonlinearity in real exchange rates dynamics, according to the level of the external debt. Our results evidence that during the monetary union, gross and net external debt positions of the euro area countries have exerted pressures on real exchange rate dynamics within the area. Moreover, we find that, beyond a threshold reached by the external debt, euro area countries are found to be in a vulnerable position, leading to an unavoidable adjustment process. Nevertheless, the adjustment process, while effective, is found to be low and occurs slowly. 相似文献
Based on an original data set of more than 500,000 non-alcoholic beverage price records, we evaluate the impact on consumer prices of the ‘soda tax’, an excise on drinks with added sugar or sweetener, introduced in France in January 2012. We adopt a difference in differences approach and find that the tax was gradually passed through to the prices of the taxed beverages. After 6 months of its introduction, it was fully shifted to soda prices and almost fully shifted to the prices of fruit drinks, while the pass-through for flavoured waters was incomplete. We also find that the pass-through was heterogeneous across brands and retail groups. 相似文献
