Characterizations of bivariate conic, extreme value, and Archimax copulas [PDF]
, 2017 Based on a general construction method by means of bivariate ultramodular copulas we construct, for particular settings, special bivariate conic, extreme value, and Archimax copulas. We also show that the sets of copulas obtained in this way are dense in

Defects and transformations of quasi-copulas [PDF]
Kybernetika, 2017 Six different functions measuring the defect of a quasi-copula, i. e., how far away it is from a copula, are discussed. This is done by means of extremal non-positive volumes of specific rectangles (in a way that a zero defect characterizes copulas). Based on these defect functions, six transformations of quasi-copulas are investigated which give rise ...

Biconic semi-copulas with a given section [PDF]
, 2013 Inspired by the notion of biconic semi-copulas, we introduce biconic semi-copulas with a given section. Such semi-copulas are constructed by linear interpolation on segments connecting the graph of a continuous and decreasing function to the points (0, 0)

Too Hot, Too Wet: Bayesian Spatial Modeling of Climate-Driven Salmonella Risk in New South Wales, Australia, 1991-2022. [PDF]
GeohealthAbstract Salmonella infections contribute significantly to gastrointestinal‐related hospitalisations in Australia and remain a major global public health concern. Although seasonal patterns in Salmonella incidence have been documented globally, there is limited evidence on the influence of climatic factors, particularly rainfall, humidity, flooding ...

Sklar's theorem in an imprecise setting [PDF]
, 2015 Sklar's theorem is an important tool that connects bidimensional distribution functions with their marginals by means of a copula. When there is imprecision about the marginals, we can model the available information by means of p-boxes, that are pairs ...

Dependence Modeling, 2013 Nelsen et al. [20] find bounds for bivariate distribution functions when there are constraints on the values of its quartiles. Tankov [25] generalizes this work by giving explicit expressions for the best upper and lower bounds for a bivariate copula ...

Final solution to the problem of relating a true copula to an imprecise copula
, 2019 In this paper we solve in the negative the problem proposed in this journal (I. Montes et al., Sklar's theorem in an imprecise setting, Fuzzy Sets and Systems, 278 (2015), 48-66) whether an order interval defined by an imprecise copula contains a copula.

The Study of Turn-taking Processes through Focus on Form and Focus on Forms Instructions: Incidental Grammar Acquisition [PDF]
Journal of Modern Research in English Language Studies, 2016 The present study aimed at examining whether the turn-taking processes in focus on form and focus on forms teaching contexts were similar or different. Turn-taking refers to ‘how each of the interlocutors in an interaction contributes to the conversation’

The Syntactic Status of Subject Clitics: A Problem from Venetan SE‐Constructions
Transactions of the Philological Society, EarlyView.Abstract This article reopens the discussion on the syntax of subject clitics (SCLs) in Venetan dialects by providing a problematic piece of data and outlining its theoretical consequences. New evidence from se‐constructions in Alto Polesine Venetan (APV) shows that SCLs resist a unitary categorisation even within the same dialect group: in varieties ...

Acquirer Strategic Orientations, Integration Decisions, and Performance
Journal of Management Studies, EarlyView.Abstract Integration decisions are not isolated, as they are embedded in an organizational context. Using a multi‐country sample (Nordics, German speaking Europe, and China) of small‐ and medium‐sized acquirers, we explore the influence of firm strategic orientations on how managers conceptualize acquisitions, make integration decisions, and impact ...
