ABSTRACT: In this paper the author analyses different types of insolvency proceedings in the context of the Italian legal system, focusing on the possible effects of bankruptcy law on employment relationships. The concept of‘privileged workers’claims is discussed, taking into account their rank of preference as stated by statutory law and according to the interpretations offered by jurisprudence. One section is expressly devoted to the recent legislation providing a Guarantee Fund for severance allowance claims in case of insolvency, but also in the event of mere nonpayment by the employer. After having covered the concept of 'super-privileged claims', the paper discusses more widely possible forms of protecting workers in a situation of company crisis and links between social legislation on the one hand, and bankruptcy law on the other. Finally, the author emphasizes the more effective protection now offered by the Italian legal system to workers’claims, although the trade unions have considerable difficulty in keeping the workforce united when insolvency proceedings are opened. 相似文献

The determinants of transnational entrepreneurship and transnational ties’ dynamics among immigrant entrepreneurs in ICT sector in Italy 下载免费PDF全文

This article contributes to the rapidly growing literature on transnational immigrant entrepreneurship by analyzing the determinants of transnational entrepreneurial engagement among immigrants in the ICT sector in Italy. We investigate which factors influence the rise or decline of transnational entrepreneurial involvement with a home country. Our results indicate that longer residence in Italy is associated with smaller propensity to become a transnational entrepreneur. Moreover, we find that the type of transnational ties and the network size have a substantial impact on the dynamics of transnational entrepreneurial engagement. 相似文献

The purpose of this paper is to present a selection of the most significant ANN (artificial neural network) applications used to solve PPC (production planning and control) problems. Therefore, the paper itself is a reasoned classification rather than a simple survey. The PPC domain is divided into various areas, and for each area one or more examples of ANNs are discussed, together with the benefits and drawbacks of their application to that particular area. Finally, two case studies developed by the authors are reported and discussed to analyse the main implementation problems to be considered when using ANNs. 相似文献

This paper contributes to the problem of estimation of state space model parameters by proposing estimators for the mean, the autoregressive parameters and the noise variances which, contrarily to maximum likelihood, may be calculated without assuming any specific distribution for the errors. The estimators suggested widen the scope of the application of the generalized method of moments to some heteroscedastic models, as in the case of state-space models with varying coefficients, and give sufficient conditions for their consistency. The paper includes a simulation study comparing the proposed estimators with maximum likelihood estimators. Finally, these methods are applied to the calibration of the meteorological radar and estimation of area rainfall. 相似文献

Thrushes (Turdus spp., Turdidae) are among the most common frugivorous birds in urban areas around the world, where they disperse the seeds
of a variety of plant species. We studied the abundance, habitat use, foraging behavior and diet of four thrush species (Turdus rufiventris, T. amaurochalinus, T. leucomelas, and T. albicollis) in a suburban area in south Brazil. Abundance, habitat use and foraging behavior were based on birds surveyed along a 3,240 m
transect crossing open (formed by lawns, streets, and buildings) and forested areas. Diet was based on fecal samples collected
from mist-netted birds. Turdus rufiventris was the most abundant species, followed by T. amaurochalinus, T. leucomelas, and T. albicollis. All species used forest fragments more frequently than expected by chance. A total of 91.8% (n = 147) of the fecal samples contained fruit remains, while 42.2% contained only animal matter. Most of the foraging records
were on the ground, where birds got mainly invertebrates. Fruits and invertebrates were eaten more frequently in open than
in forested areas. A total of 25 seed morfospecies were found in the droppings, including five exotic plant species. Thrushes
overlapped widely in the fruit composition of their diets. The high abundance and degree of frugivory, coupled with the frequent
use of forest patches, indicate that thrushes are among the great bird contributors to the seed dispersal occurring in urban
forest patches, potentially influencing the vegetation dynamics of such habitats so important for the maintenance of the biodiversity
in urban areas. 相似文献

Marco Catarci 《Intercultural Education》2013,24(5):456-475
The present article focuses on quantitative research carried out on a statistically representative sample of Italian primary schools with a high concentration of immigrant students. Research data show that schools with a higher number of immigrant students offer a greater number and a wider variety of intercultural initiatives. The presence of immigrant students serves as an effective stimulus in enhancing intercultural approaches. Furthermore, the opinions of head teachers about the proposal of ‘separate classes’ for immigrant students and the proposed ‘limit of 30% on the presence’ of immigrant students are negative. These judgements do not change in a statistically significant manner in relation to concentration of immigrant students: in particular, higher rates of immigrant students are not related to more positive opinions. Continuing education on intercultural issues is widely adopted, mainly on behalf of teachers and less often on behalf of head teachers and other school personnel. Finally, activities by ‘linguistic facilitators’ and ‘linguistic and cultural mediators’ are not significantly related to a decrease in perceived concern regarding problematic situations. 相似文献

We formulate and investigate experimentally a model of how individuals choose between time sequences of monetary outcomes.
The model assumes that a decision maker uses, sequentially, two criteria to screen options. Each criterion only permits a
decision between some pairs of options, while the other options are incomparable according to that criterion. When the first
criterion is not decisive, the decision maker resorts to the second criterion to select an alternative. We find that: (1)
traditional economic models based on discounting alone cannot explain a significant (almost 30%) proportion of the data no
matter how much variability in the discount functions is allowed; (2) our model, despite considering only a specific (exponential)
form of discounting, can explain the data much better solely thanks to the use of the secondary criterion; (3) our model explains
certain specific patterns in the choices of the “irrational” people. We reject the hypothesis that anomalous behavior is due
simply to random “mistakes” around the basic predictions of discounting theories: deviations are not random and there are
clear systematic patterns of association between “irrational” choices. 相似文献
