Summary The paper shows that the informaton matrix test presented by White (1982) decomposes into the sum of quadratic forms in the
case of a linear model with ARMA errors. By extending previous results, which analysed the information matrix test in the
presence of serial correlation, the test allows detection of additional sources of misspecification. 相似文献

In the present paper we start the study of arcs with weighted points in a finite projective plane, and we get some particular results about the existence or non-existence of these arcs. 相似文献

ABSTRACT‘The Internet is the fabric or our lives’ [Castells, M. (2001). The Internet Galaxy: Reflections on the Internet, Business, and Society. Oxford: Oxford University Press, p. 1] – but which are the weaves that nowadays connect Italian social workers into such a fabric? Herein we aim at answering this question through a survey of on-line resources, nodes and practices of e-Social Work in Italy. We shall be discussing ICT impact on the Italian context, and the utilization of ICT by Italian social workers, in order to build up the internal and external factors that determine the current utilization levels of these emerging tools within the professional community. A review of the major on-line social work portals will identify their key features and peculiarities and aim to provide an overview of the substance and current on-line functions of Italian social work, with a summing-up of criticalities and opportunities that might prompt reflection on possible future developments. 相似文献

In spite of relatively generous public subsidies and a reputation for high quality, only a very limited proportion of Italian
families use public child-care and a large proportion use informal care. In this paper, we attempt to explore the determinants
of the use of child-care among dual workers families. Given the limitations of data available we match two different data
sets: the Bank of Italy (SHIW) and ISTAT Multiscopo. We find evidence that the availability of public child-care affects in
an important way its demand. We also find that increases in costs of public child-care reduce the use of public as well as
private indicating a shift to informal child-care. The presence of a grandmother who lives near and is in good health is an
important explanation of the choice especially in presence of very small children. An understanding of the importance of these
factors is relevant in the evaluation of child-care policies. This is particularly important in Italy, where the majority
of families with children have only one child and children would benefit also from the socialization aspects of the child-care
system.

Various waves of asylum seekers and resettled refugees arriving in Canada since the 1980s reflect the eruption of war and ethnic conflicts in parts of Africa, Central America, and South East Asia. Contrary to long‐established immigrant communities such as the Greeks, Italians, and Portuguese, these newcomers have had to fend for themselves and develop their own support networks, leading to new forms of organizing and to the formation of refugee community organizations (RCOs). This article discusses the findings of a 2008–2011 study on RCOs in Canada, specifically in Montréal and Winnipeg. The objective of the study was to understand the context in which RCOs have developed, the populations they serve, and the role they play in their ethnic communities. Working within the RCO paradigm, we analyze the creation of these organizations, contrast findings with research done in the UK, and raise issues for social work practice. Key Practitioner Message: ● Innovative research in Canada documenting refugee community organizations gives fresh insight regarding community organizing practice; ● Documents the situation of asylum seekers and refugees on an individual and a collective basis in terms of needs; ● Focuses on the necessity of building bridges with refugee organizations to bring them into the mainstream. 相似文献

The paper compares the existing tests for parameter instability in quantile regression. One is based on the estimated objective function and the other on the gradient. Their definition determines their characteristics and helpfulness. The former allows to check if the impact of a break on the entire equation changes across quantiles while a modified version of the latter verifies if the break affects only some coefficients or all of them and helps locating the break point. In addition the paper presents a Lagrange multiplier test for structural break. The advantage of the LM test is in the ease of implementation, since it simply requires the estimation of an auxiliary regression. An example shows the characteristics of each test. A Monte Carlo study concludes the analysis. 相似文献

Aggregate evidence has revealed a significant increase in women’s labour market participation (especially among married women) and a decline in male participation, both in Italy and in all the other OECD countries. This paper empirically tests the relationship between the education and employment status of husbands and wives using the Bank of Italy Survey (1995). The results of our analysis show that employed women are likely to be married to employed men with a higher level of education and higher income. The estimates of the labour supply decisions of wives show that the effect of the unemployment status of husbands is mediated by other factors associated with the family’s view of wives working outside home. The response to a husband’s unemployment depends significantly on the employment decisions of parents (mothers and mothers‐in‐law), a proxy for the couple’s attitude towards women’s work. 相似文献
