On Decomposing Net Final Values: Eva,Sva and Shadow Project 总被引:1,自引:0,他引:1
A decomposition model of Net Final Values (NFV), named Systemic Value Added (SVA), is proposed for decision-making purposes, based on a systemic approach introduced in Magni [Magni, C. A. (2003), Bulletin of Economic Research 55(2), 149–176; Magni, C. A. (2004) Economic Modelling 21, 595–617]. The model translates the notion of excess profit giving formal expression to a counterfactual alternative available
to the decision maker. Relations with other decomposition models are studied, among which Stewart’s [Stewart, G.B. (1991),
The Quest for Value: The EVA™ Management Guide, Harper Collins, Publishers Inc]. The index here introduced differs from Stewart’s Economic Value Added (EVA) in that it
rests on a different interpretation of the notion of excess profit and is formally connected with the EVA model by means of
a shadow project. The SVA is formally and conceptually threefold, in that it is economic, financial, accounting-flavoured. Some results
are offered, providing sufficient and necessary conditions for decomposing NFV. Relations between a project’s SVA and its
shadow project’s EVA are shown, all results of Pressacco and Stucchi [Pressacco, F. and Stucchi, P. (1997), Rivista di Matematica per le Scienze Economiche e Sociali 20, 165–185] are proved by making use of the systemic approach and the shadow counterparts of those results are also shown. 相似文献

Public transit is now a major power exercised by regions in France. The regionalization of public transportation, which started in the early 1980s, is analyzed in relation to a new pattern of major players, namely: the central government, local authorities and the French national railway system (SNCF). This pattern has emerged as a compromise, has gradually been worked out between two rationales: the one advocating a revival of local rail services; and the other, the preservation of funding by the state and the SNCF. Arising out of a work of mediation and out of strategies for enlisting reformers (mainly among politicians and from the SNCF) into a coalition, this compromise has bought about an ambiguous consensus among elected officials from left- and right-wing parties, executives from the SNCF, elected regional officials and representatives of railway workers who do not all share a priori either the same interests or the same conception of the general interest. 相似文献

Abstract The effects of a primary prevention social norm intervention on binge drinking among 1st-year residential college students were examined. Six hundred thirty-four students attending a medium-sized public university in the South were randomly assigned to receive a two-phase social norm intervention or the standard campus psychoeducational prevention program. At posttest, no differences were found between intervention and control group students on any of the alcohol use and alcohol-use risk factor measures. Significant subgroup differences were found by stage of initiating binge drinking behaviors, for frequency of alcohol use, F(3, 507) = 3.69, p = .01; quantity of alcohol use, F(3, 507) = 2.51, p = .05; and social norms, F(3, 505) = 2.53, p = .05. These findings suggest the need for tailoring social norm binge drinking interventions to students' stage of initiating heavy drinking and carefully monitoring for potential negative, as well as positive, effects of norm-based prevention messages. 相似文献

Intensity functions—which describe the spatial distribution of the occurrences of point processes—are useful for risk assessment.
This paper deals with the robust nonparametric estimation of the intensity function of space–time data from events such as
earthquakes. The basic approach consists of smoothing the frequency histograms with the local polynomial regression (LPR)
estimator. This method allows for automatic boundary corrections, and its jump-preserving ability can be improved with robustness.
We derive a robust local smoother from the weighted-average approach to M-estimation and we select its bandwidths with robust
cross-validation (RCV). Further, we develop a robust recursive algorithm for sequential processing of the data binned in time.
An extensive application to the Northern California earthquake catalog in the San Francisco, CA, area illustrates the method
and proves its validity. 相似文献

This article reports findings from a collaborative study of UK student learning in Malaysia. We analyze the concept of liminality as a means of understanding the transitional process between states and statuses that social work students experience in practice learning. Here, in specific reference to immersion in new cultural contexts represented by international placements, the development and learning of students are explored in relation to the overlapping domains of familiar and unfamiliar ‘cultures’ and disciplinary practice. These findings carry implications in terms of the increasing popularity of international placements and the potential imposition of hegemonies of values and knowledge. 相似文献

Abstract Objective: To examine whether young adult cigarette smokers who were in the precontemplation and contemplation stages of change for smoking cessation would differ in their evaluations of vignettes depicting 2 types of physician advice. Participants: Fifty-seven young adult cigarette smokers who were undergraduate students (49.1% female, mean age = 20.4 years) attending an urban university. Methods: Participants evaluated 2 written vignettes. Both vignettes depicted physicians using patient-centered communication styles. One vignette depicted a physician giving a patient direct advice to quit smoking and the other a physician using a motivational style of advice. Data were collected from September 2004 through May 2005. Results: Participants rated the motivational advice vignette as significantly more favorable compared to the direct advice vignette on all assessed dimensions (global satisfaction, general satisfaction, physician affective style, physician technical style, and physician communication style). Conclusion: Smokers preferred the motivational advice style to simple patent-centered advice. 相似文献

This article's core idea is that body modification can be seen as a nonstandard symbolic expression of a long-standing project of the enlightenment: to control human destiny, with the dream of conquering death. This idea is based on experimentally validated tenet of existential psychology that the denial of death is one of humanity's deepest motivations. The first highlights a common denominator in the articles by Pitts-Taylor, Sullivan, and Knafo: they courageously oppose the knee-jerk reaction that body modification necessarily entails giving in to social or gender pressure. Instead each proposes refined psychodynamic hypotheses. Knafo's analysis of body artist Orlan is taken as the starting point for an elaboration of this cultural phenomenon as a reflection of the denial of death. 相似文献

Bullying and Victimization Among School-age Children: Stability and Links to Proactive and Reactive Aggression 总被引:4,自引:1,他引:3

The main aim of the study relates to the links between bullying and victimization on the one hand and reactive and proactive aggression on the other. In addition, we also investigated stability and incidence of bullying and victimization. At age 7, 236 children were rated on bullying and victimization using peer reports. At age 8, 242 children were rated again. Two hundred and fifteen children (114 girls and 101 boys) were present at both time points. Reactive and proactive aggression was assessed by teachers. The results showed that bullies and bully/victims were both reactively and proactively aggressive, while victims were only reactively aggressive. A moderate degree of stability of bullying and victimization was found, with bullying being more stable than victimization. Boys were more often bullies than girls and more stable than girls in victimization. Stable victims and stable bully/victims were more reactively aggressive than their unstable counterparts. The relevance of the outcomes to preventing future maladjustment and suggestions for further research are discussed. 相似文献
