Copula-based regression models: A survey

In this review paper we collect several results about copula-based models, especially concerning regression models, by focusing on some insurance applications.     

A case–control study relating railroad worker mortality to diesel exhaust exposure using a threshold regression model

A case–control study of lung cancer mortality in U.S. railroad workers in jobs with and without diesel exhaust exposure is reanalyzed using a new threshold regression methodology. The study included 1256 workers who died of lung cancer and 2385 controls who died primarily of circulatory system diseases. Diesel exhaust exposure was assessed using railroad job history from the US Railroad Retirement Board and an industrial hygiene survey. Smoking habits were available from next-of-kin and potential asbestos exposure was assessed by job history review. The new analysis reassesses lung cancer mortality and examines circulatory system disease mortality. Jobs with regular exposure to diesel exhaust had a survival pattern characterized by an initial delay in mortality, followed by a rapid deterioration of health prior to death. The pattern is seen in subjects dying of lung cancer, circulatory system diseases, and other causes. The unique pattern is illustrated using a new type of Kaplan–Meier survival plot in which the time scale represents a measure of disease progression rather than calendar time. The disease progression scale accounts for a healthy-worker effect when describing the effects of cumulative exposures on mortality.

Efficacy of Statistical Outlier Analysis for Monitoring Quality of Care

Researchers have proposed that hospitals with excessive statistically unexplained mortality rates are more likely to have quality-of-care problems. The U.S. Health Care Financing Administration currently uses this statistical “outlier” approach to screen for poor quality in hospitals. Little is known, however, about the validity of this technique, since direct measures of quality are difficult to obtain. We use Monte Carlo methods to evaluate the performance of the outlier technique as parameters of the true mortality process are varied. Results indicate that the screening ability of the technique may be very sensitive to how widespread quality-related mortality is among hospitals but insensitive to other factors generally thought to be important.     

Bootstrap test of hypothesis for the multi-state models in survival analysis

Abstract

In the present paper we develop bootstrap tests of hypothesis, based on simulation, for the transition probability matrix arising in the context of a multi-state model. The bootstrap test statistic is based on the paper of Tattar and Vaman (2008 Tattar, P. N., Vaman, H. J. (2008). Testing transition probability matrix of a multi-state model with censored data. Lifetime Data Anal. 14(2):216–230.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), which develops a statistic for the testing problems concerning the transition probability matrix of the non homogeneous Markov process.     

The multiethnic state-building dilemma: national and ethnic minorities' identities in the Crimea

This article examines the process of national identity formation among ethnic minorities in the Crimea – specifically, how a new common identity develops in the system of existing identities, what meaning group identities have for different minorities group and how this process influences attitudes and stereotypes toward the ingroup and outgroup. Based on surveys in the Crimea, results show that formation of a common national and regional identity leads to developing of positive stereotypes toward members of other groups, who now are involved in a new group identity, but also is connected with formation of negative attitudes and stereotypes toward other groups. The meaning of identity depends on its position in the system of identities and can be used as a criterion for early warning of conflicts.     

Rhetorical Theory and the Critique of National Identity Construction

A striking feature of scholarship on national identity is the relative absence of rhetorical theory, or theory related to the persuasive dimensions of discourse, especially given the fact that rhetorical theorists have been concerned with the manufacturing of public opinion and collective identity for over two millennia. To address this absence, this article discusses how rhetorical theories dealing with narrative theory, the social construction of publics, rhetorical constraints, ideology critique, public memory, political history and post-national identity help both to illuminate and critique emergent patterns of national identification.     

Violent civic nationalism versus civil ethnic nationalism: Contrasting Indonesia and Malay(si)a

In 1963 the Federation of Malaya, Singapore, Sarawak, and Sabah formed the Federation of Malaysia. In the same year Indonesia gained control over West Papua. In the first case the integration was accomplished participatory and peacefully, in the second violence reigned supreme. I argue that different visions of community, nation and state, developed during the decades of decolonisation and the early years of state- and nation-building, are responsible for the different outcomes. Contrary to the expectations of the predominant theories on nationalism the ethno-cultural variant of nation-building in Malaysia proved to be much more integrative than the civic variant espoused by the Indonesian nation-builders.

Overcoming the ‘tyranny of the urgent’: integrating gender into disease outbreak preparedness and response

ABSTRACT

This article contributes to discussions on the gender dimensions of disease outbreaks, and preparedness policies and responses, by providing a multi-level analysis of gender-related gaps, particularly illustrating how the failure to challenge gender assumptions and incorporate gender as a priority at the global level has national and local impacts. The implications of neglecting gender dynamics, as well as the potential of equity-based approaches to disease outbreak responses, is illustrated through a case study of the Social Enterprise Network for Development (SEND) Sierra Leone, a non-government organisation (NGO) based in Kailahun, during the Ebola outbreak.
