Over the past two decades the link – perceived and actual – between political extremism and football fans has been the subject of academic, political, and policing debate. It is not rare to witness manifestations of intolerance and ideological statements referring to regional, national and international issues at football stadia. In Italian football stadia, political representation has been evident for decades; politics has been integral to all realms of Italian society and culture since the origin of the nation. As one of the most significant Italian cultural practices, football has not been an exception. This combination of theory and action inspires thousands of young male football supporters. The football stadium might thus be interpreted as a twenty-first century social Agorá, where political opinions – otherwise ghettoized in society – can be freely expressed in pursuit of a wider consensus. This paper explores the under-researched milieu of neo-fascist ideology as displayed in contemporary Italian football stadia. Contributing original material and employing as conceptual frameworks the New Consensus Theory on fascism and the works of Julius Evola and Georges Sorel, this analysis hypothesizes that the neo-fascist tenets manifested by the ideologically-oriented ‘ultras’ fan groups, may be understood as both a consequence of, and a resistance against the dominant socio-cultural and political values of contemporary Italy. The research conducted between 2003–2007 sought to evaluate two internationally renowned ultras groups located in the Italian capital of Rome: the Boys of AS Roma and the Irriducibili of SS Lazio who enact their performances on their respective ‘curve’ [football terraces] of the city's Olympic stadium. Utilizing the ethnographic method, unique access was achieved in a notoriously difficult research milieu bringing the researcher into the social-cultural world of the participants and to the echelons of the extra-parliamentary Italian far right. Research sought to uncover the groups’ social interactions, values, and political beliefs, as a way of contributing to an understanding of both the Italian ultras of the twenty-first century and indeed the wider political milieu of the modern nation-state of Italy.  相似文献

Most marital and family therapists, both medically and nonmedically trained, regularly interact with physicians on a professional basis. Though some physicians receive specific training in marital and family therapy in their postgraduate residency programs, (notably those in psychiatry and family medicine), for many, the only academic exposure they receive to this field comes during a 6- to 10-week clinical clerkship in psychiatry during their third or fourth year of medical school. No study could be located which examined marital and family therapy training in undergraduate medical education. The purpose of this study was to gain a better understanding of the level of marital and family therapy training in medical school and to provide information concerning physicians who are not family therapists, and how much knowledge about the field they can be expected to have.  相似文献

In the normal regresion model, a relation between the notion of estimability of a distribution and the existence of a linear function of the observations with some desired property is studied. Several definitions of estimability are shown to be equivalent.  相似文献

39% of the Philippines youth are not in school and these youths receive no training for responsible parenthood and community life. A number of agencies try to reach these members of society, including the Bureau of Youth Welfare (BYW), the Family Planning Organization of the Philippines (FPOP), the Foundation for Youth Development in the Philippines (FYDP), the Rizal Youth Development Foundation (RYDF), the Philippine Rural Reconstruction Movement (PRRM), and the Philippine Youth Welfare Coordinating Committee. BYW conducts informal group sessions including discussions among 13-24 year old members who have started self-employment projects. FPOP's youth program, SIGLA, aims at developing out-of-school youths social y and having them disseminate information to other out of school youths. This information includes family development, family planning, and population-related information, and is disseminated through activities and workshops. FYDP aims at functional literacy but also disseminates family planning information to out-of-school youths. RYDF conducts week-long seminars in topics such as birth processes, family relations, and care of babies. PRRM integrates population and family planning into its nonformal education program for out-of-school youth and adults in Nueva Ecija Province. Problems encountered in these programs are 1) suspicion of parents, and 2) feelings of inadequacy on the part of teachers. While emphasis has been on unemployed youth, efforts should be made to reach those youth who are employed.  相似文献

A procedure to derive optimal discrimination rules is formulated for binary functional classification problems in which the instances available for induction are characterized by random trajectories sampled from different Gaussian processes, depending on the class label. Specifically, these optimal rules are derived as the asymptotic form of the quadratic discriminant for the discretely monitored trajectories in the limit that the set of monitoring points becomes dense in the interval on which the processes are defined. The main goal of this work is to provide a detailed analysis of such optimal rules in the dense monitoring limit, with a particular focus on elucidating the mechanisms by which near-perfect classification arises. In the general case, the quadratic discriminant includes terms that are singular in this limit. If such singularities do not cancel out, one obtains near-perfect classification, which means that the error approaches zero asymptotically, for infinite sample sizes. This singular limit is a consequence of the orthogonality of the probability measures associated with the stochastic processes from which the trajectories are sampled. As a further novel result of this analysis, we formulate rules to determine whether two Gaussian processes are equivalent or mutually singular (orthogonal).

We give a theoretical answer to a natural question arising from a few years of computational experiments on the problem of sorting a permutation by the minimum number of reversals, which has relevant applications in computational molecular biology. The experiments carried out on the problem showed that the so-called alternating-cycle lower bound is equal to the optimal solution value in almost all cases, and this is the main reason why the state-of-the-art algorithms for the problem are quite effective in practice. Since worst-case analysis cannot give an adequate justification for this observation, we focus our attention on estimating the probability that, for a random permutation of n elements, the above lower bound is not tight. We show that this probability is low even for small n, and asymptotically (1/n5), i.e., O(1/n5) and (1/n5). This gives a satisfactory explanation to empirical observations and shows that the problem of sorting by reversals and its alternating-cycle relaxation are essentially the same problem, with the exception of a small fraction of pathological instances, justifying the use of algorithms which are heavily based on this relaxation. From our analysis we obtain convenient sufficient conditions to test if the alternating-cycle lower bound is tight for a given instance. We also consider the case of signed permutations, for which the analysis is much simpler, and show that the probability that the alternating-cycle lower bound is not tight for a random signed permutation of m elements is asymptotically (1/m2).  相似文献

This study examines the individual effects of product diversification on performance and the moderating effects of international diversification on the product diversification–performance link in the context of a boom and bust cycle. Most prior research on firm strategies largely neglect the business cycle. We use data on a large sample of Spanish manufacturing firms from 1994 to 2014. In this period, the Spanish economy experienced a boom period (1994–2008) and a bust period involving a severe economic crisis (2009–2014). Our study highlights the important role of each stage of the economic cycle. Specifically, with respect to product diversification, our findings show that in a boom, moderate diversifiers obtain better profitability levels than their highly diverse or limited diversification counterparts do. In contrast, during an economic downturn, moderate and high diversifiers can be equally effective up to some point of optimization. Our findings also reveal a negative and significant effect of internationalization on profitability, independent of the stage of the economic cycle. Product and international diversification are complementary strategies during a period of economic growth when firms opt for moderate levels of product diversification. Meanwhile, when firms choose high levels of product diversification, both types of strategies are complementary during the boom cycle, but substitutive during the bust cycle.  相似文献

We develop a discrete variant of a general model for adult mortality influenced by the delayed impact of early conditions on adult health and mortality. The discrete variant of the model builds on an intuitively appealing interpretation of conditions that induce delayed effects and is an extension of the discrete form of the standard frailty model with distinct implications. We show that introducing delayed effects is equivalent to perturbing adult mortality patterns with a particular class of time-/age-varying frailty. We emphasize two main results. First, populations with delayed effects could experience unchanging or increasing adult mortality even when background mortality has been declining for long periods of time. Although this phenomenon also occurs in a regime with standard frailty, the distortions can be more severe under a regime with Barker frailty. As a consequence, conventional interpretations of the observed rates of adult mortality decline in societies that experience Barker frailty may be inappropriate. Second, the observed rate of senescence (slope of adult mortality rates) in populations with delayed effects could increase, decrease, or remain steady over time and across adult ages even though the rate of senescence of the background age pattern of mortality is time- and age-invariant. This second result implies that standard interpretations of empirical estimates of the slope of adult mortality rates in populations with delayed effects may be misleading because they can reflect mechanisms other than those inducing senescence as conventionally understood in the literature.  相似文献
