This study concerns the market for research collaboration between industry and universities. It presents an analysis of the
population of all Italian university–industry collaborations that resulted in at least one international scientific publication
between 2001 and 2003. Using spatial and bibliometric analysis relating to scientific output of university researchers, the
study shows the importance of geographic proximity in companies’ choices of university partner. The analysis also reveals
inefficiency in the market: in a large proportion of cases private companies could have chosen more qualified research partners
in universities located closer to the place of business. 相似文献

This article uses economic categories to show how the reorganisation of civil procedure in the case of class action is not
merely aimed at providing a more efficient litigation technology, as hierarchies (and company law) might do for other productive
activities, but that it also serves to create a well defined economic organization ultimately aimed at producing a set of
goods, first and foremost among which are justice and efficiency. Class action has the potential to recreate, in the judicial
domain, the same effects that individual interests and motivations, governed by the perfect competition paradigm, bring to
the market. Moreover, through economic analysis it is possible to rediscover not only the productive function of this legal
machinery, but also that partial compensation of victims and large profits for the class counsel, far from being a side-effect,
are actually a necessary condition for reallocation of the costs and risks associated with the legal action. 相似文献

New Public Management (NPM) recently has been compared and contrasted with public governance (PG) to illustrate shifts in conceptions of public administrations and in reform agendas. The authors develop measures to capture the relevance of NPM and PG in textual discourse and investigate the extent to which they have entered the political debate. Content analysis of electoral programs for the 2005 Italian regional elections reveals that even in this legalistic country, considerable attention was paid to both NPM and PG issues. An important explanatory variable in preference for NPM or PG is party ideology, highlighting often‐ignored within‐country dynamics. Furthermore, the authors show how a methodological approach adapted from mainly political science and business research can be exploited in the field of public administration. 相似文献

New Italian legislation on driving under the influence of drugs considers oral fluid (OF) as a possible alternative drug testing matrix. On this basis, the present research was carried out to evaluate the applicability of four commercial on-site OF drug screening devices, namely DDS(?), Drugtest 5000(?), Drugwipe 5+(?) and RapidSTAT(?), in a real operative context. Preliminarily trained police officers tested randomly stopped drivers with two different kits side-by-side during roadside patrols. A central laboratory confirmed on-site kits' results by UHPLC-MS/MS analysis of the saliva specimen remaining after the screening analysis. 1025 drivers were submitted to the OF tests: 11.6% were positive for cocaine and metabolites, 11.1% for THC, 6% for amphetamines and amphetamine-type designer drugs and 2.3% for ketamine. The sensitivities of the kits were 81% (RapidSTAT(?)), 82% (DDS(?)), 90% (Drugwipe 5+(?)) and 97% (Drugtest 5000(?)) for cocaine and 38% (DDS(?)), 47% (Drugwipe 5+(?)), 72% (RapidSTAT(?)) and 92% (Drugtest 5000(?)) for THC. Drugtest 5000 was the only kit showing an acceptable sensitivity for on-site application. Only Drugtest 5000(?) and RapidSTAT(?) could be evaluated for amphetamines and methamphetamines: Drugtest 5000(?) showed a sensitivity of 100% in the case of amphetamines and 86% for methamphetamines, while RapidSTAT(?) 90% and 76% respectively. Nowadays, ketamine is not included in the target analytes of any on-site devices, but it was systematically included in the UHPLC-MS/MS confirmatory analysis. To ensure adequate reliability, MS confirmation of on-site OF screening tests is anyway always necessary, due to the presence of a significant number of false positive results even when using the commercial kit with the best performance. 相似文献

Evidence of exposure of a metal component to a small charge explosion can be detected by observing microstructural modifications; they may be present even if the piece does not show noticeable overall plastic deformations. Particularly, if an austenitic stainless steel (or another metal having a face-centered cubic structure and a low stacking fault energy) is exposed to an explosive shock wave, high-speed deformation induces primarily mechanical twinning, whereas, in nonexplosive events, a lower velocity plastic deformation first induces slip. The occurrence of mechanical twins can be detected even if the surface is damaged or oxidized in successive events. In the present research, optical metallography (OM) and scanning electron microscopy (SEM), and scanning tunneling microscopy (STM) were used to detect microstructural modifications caused on AISI 304Cu steel disks by small-charge explosions. Spherical charges of 54.5 or 109 g TNT equivalent mass were used at explosive-to-target distances from 6.5 to 81.5 cm, achieving peak pressures from 160 to 0.5 MPa. Explosions induced limited or no macro-deformation. Two alloy grain sizes were tested. Surface OM and SEM evidenced partial surface melting, zones with recrystallization phenomena, and intense mechanical twinning, which was also detected by STM and X-ray diffraction. In the samples' interior, only twins were seen, up to some distance from the explosion impinged surface and again, at the shortest charge-to-sample distances, in a thin layer around the reflecting surface. For forensic science locating purposes after explosions, the maximum charge-to-target distance at which the phenomena disappear was singled out for each charge or grain size and related to the critical resolved shear stress for twinning. 相似文献

The issue of instability in a simple policy game between the central bank and a representative union
In the recent economic literature the independence of the central bank is often considered to be one of the most effective guarantees to achieve price stability. A strong theoretical basis for this proposition is that the monetary policy delegation given to an independent central bank is an optimal instrument to avoid the time inconsistency problem of monetary policy. This paper investigates the stability properties of this solution in a simple game in which the private sector (i.e. the trade unions) and the public sector (i.e. the central bank) simultaneously interact. A representative monopoly union is considered, and – in line with the recent economic debate – two types of unions are investigated: (i) the standard micro-founded trade union; (ii) the inflation-averse trade union. In both cases, we find that the requirement for the Nash equilibrium to be stable imposes a limit to the conservativeness of the central bank. Instability of the Nash equilibrium reveals a strategic co-ordination failure between the public and the private sector. 相似文献

Accumulation by Dispossession and Its Limits: The Southern Africa Paradigm Revisited 总被引:1,自引:0,他引:1
Giovanni Arrighi Nicole Aschoff Ben Scully 《Studies in Comparative International Development (SCID)》2010,45(4):410-438
The dispossession of agricultural producers from the land has long been considered a condition of successful capitalist development.
The main contention of this paper is that such dispossession has in fact become the source of major developmental handicaps
for at least some and possibly many countries of the global South. We develop our argument by focusing on the South(ern) African
experience as a paradigmatic outlier case of accumulation by dispossession—that is, as one of its extreme instances capable
of highlighting in almost ideo-typical fashion its nature and limits. After reconstructing interpretations of capitalist development
in Southern Africa that in the early 1970s established the region as a paradigm of accumulation by dispossession, we discuss
how useful these interpretations are for understanding the more recent developmental trajectory of South Africa. We then suggest
ways in which these interpretations from the 1970s should be reformulated in light of subsequent developments. We conclude
by briefly examining the theoretical and policy implications of the analysis. 相似文献

The paper argues for viewing legal validityas a doxastic obligation, i.e. as the obligation toaccept a rule in legal reasoning. This notion of legalvalidity is shown to be both sufficient for thelaywers' needs and neutral in regard to varioustheories of the grounds of validity, i.e. theoriesintended to identify what rules are legally valid, byproposing different grounds for attributing validity.All of these theories, rather then being alternativedefinitions of validity, presuppose the notion hereprovided.This notion is purely normative, but it allows for theconstruction of theories of the grounds of validitywhich give due importance to social expectations andinstitutions. As an example of how this may happen,one such theory is also provided. This theory, whichis presented through a detailed example of a judicialdebate, is based upon the recognition of the(instrumental) value of co-ordination, as thenecessary way to achieve the most valuable purposes ofthe law. 相似文献

Our data on investment in Central and Eastern European economies reveal that, though investment rates were typically high in the 1970s, the marginal efficiency of investment was low. Investment shares begun to decline in the 1980s, before the collapse of the communist system, but there was some recovery in most countries after transition. We use the Kalman filter framework to test for convergence in investment rates. We find some evidence of convergence in Central European countries – former Czechoslovakia, Poland and the countries of the former Yugoslavia. For the remainder of the socialist bloc, however, we were unable to isolate convergence in investment shares. 相似文献
