A goodness-of-fit test for the random-effects distribution in mixed models
No full text© The Author(s) 2014. In this paper, we develop a simple diagnostic test for the random-effects distribution in mixed models. The test is based on the gradient function, a graphical tool proposed by Verbeke and Molenberghs to check the impact of assumptions about the random-effects distribution in mixed models on inferences. Inference is conducted through the bootstrap. The proposed test is easy to implement and applicable in a general class of mixed models. The operating characteristics of the test are evaluated in a simulation study, and the method is further illustrated using two real data analyses
Sepedon (Parasepedon) hispanica subsp. ruhengeriensis Verbeke 1950
No full textSepedon (Parasepedon) hispanica Loew ssp. ruhengeriensis Verbeke, 1950 Synonym by Verbeke (1964). (Figs 15, 17, 18, plate 9) References to figures: Verbeke 1950 (aedeagus, surstylus); Verbeke 1961 (surstylus). Knutson et al. 1967 (S. h. hispanica: egg; I, II, III instar cephalopharyngeal skeleton and posterior spiracular disc; II, III instar anterior spiracle, puparium). Holotype: ♂, RWANDA: Ruhengeri (sources Kiri), 1800–1825m, 31.viii.1934, (Mission G.F. de Witte) (MRAC). Seen by Knutson in 1978 in IRSNB, Cabinet 41, “Parc National Albert”, Box. 1. Verbeke, 1950 placed his S. ruhengeriensis and four other new species (S. lippensi, S. saegeri, S. simulans and S. uelensis) along with S. trichroocelis Speiser, 1910 in his “Groupe G (Groupe trichrooscelis)” of the subgenus Parasepedon. Verbeke (1963) placed S. parvipennis Steyskal, 1956 in this group, but that species was synonymized under S. saegeri in Verbeke (1963) and confirmed by Verbeke in litt. 1968 in his review of his MS of Knutson (1980). Knutson et al. (1967) noted “ Sepedon h. hispanica was described from one female collected in Andalusia (Loew, 1862). The species was apparently not seen by most European dipterists and its validity was in doubt until it was rediscovered by the senior author in Andalusia in 1964. Specimens were sent to Dr. J. Verbeke, who identified them as conspecific with the type specimen of Loew. Verbeke (1964) placed S. ruhengeriensis Verbeke, 1950 (described from tropical Africa) as a junior synonym of S. hispanica Loew 1862. The populations from Spain and Africa were considered subspecifically distinct and were given the trivial names of S. h. hispanica Loew and S. h. ruhengeriensis Verbeke, respectively. Keys to the six species were presented by Verbeke (1950, 1961). Verbeke (1961) placed the species in 3 “categories” (trichrooscelis + lippensi, saegeri + uelensis, and hispanica + simulans). Recent study of extensive material indicates that there are several additional species in this Group. In West Africa S. hispanica ruhengeriensis is most similar to S. trichrooscelis. In general, specimens of S. h. ruhengeriensis are larger than those of S. trichrooscelis and the femora are more distinctly reddened. The prosternum is usually more densely setose in S. hispanica ruhengeriensis than in S. trichrooscelis. The frons of S. hispanica ruhengeriensis is generally in part yellowish brown, but in S. trichrooscelis it is usually shiny black. NIGERIA: Zaria, Samaru, 1♂, 24.vii.1968 (USNM).

Mapping the Dynamics of European Culture - Pressure and Opportunities from the European Enlargement
No full textThis paper develops an analytic framework for the ESPON 1.3.3 project “The Role and Spatial Effects of Cultural Heritage and Identity”, started in December 2004 by a network of 12 European Universities under the leadership of Ca’ Foscari University of Venice. The conceptual framework of this project lies on the assumption that the cultural heritage of Europe is not just an ensemble of tangible assets to be defended through passive conservation, but rather an element of dynamism of the territory, affecting trajectories of regional development. Thus the proper identification and valorisation of the cultural heritage of Europe is to be considered an integral component of regional planning, with the potential to increase cohesion within an enlarged European Union. The establishment of an “European identity”, gaining from difference and variety, is also part of this vision. In this light, the ESPON 1.3.3 project sets out to highlight the spatial expressions and effects of heritage assets and identify the (existing or potential) elements of territorial coherence at the regional and local scale, mapping the geographical aspects that are actually strengthening regional identities and networks. This paper introduces a list of regional indicators of the European cultural heritage and identity, reflecting elements such as heritage availability, concentration and diversity, spatial patterns at the local and cross-regional level, local embeddedness of intangible heritage assets, pressures on- and potential for the development of heritage, and the governance structure of the heritage management institutions. Parameters are quantitative and qualitative observation allowing the “ordering” of the territory and thus the identification of regional typologies from the elaboration of different ordering criteria. Indicators will cover multiple dimensions regarding the supply, the demand and the spatial organisation of cultural heritage. Data cover the whole NUTS III regional delimitation. The issue of the territorial cohesion of cultural heritage assets is also addressed, considering the following multiple “dimensions” of the interconnection between different “objects” or carriers of meaning: hardware (the infrastructural system), software (images and actual uses), orgware (organizational networks) and shareware (partnerships that support the process of development). These elements are compiled in a framework or model used to analyse the territorial expressions of cultural heritage and identity.
Performance of classification models from a user perspective
No full textThis paper proposes a complete framework to assess the overall performance of classification models from a user perspective in terms of accuracy, comprehensibility, and justifiability. A review is provided of accuracy and comprehensibility measures, and a novel metric is introduced that allows one to measure the justifiability of classification models. Furthermore, taxonomy of domain constraints is introduced, and an overview of the existing approaches to impose constraints and include domain knowledge in data mining techniques is presented. Finally, justifiability metric is applied to a credit scoring and customer churn prediction case

Consumer Interest and Marketing Potential of Information on Fish Labels
No full textFood labels are an important source of information to consumers. However, little scientific evidence is available on the type of information consumers seek on product labels and how consumers use food labels. The objective of this study is to assess consumers’ use of mandatory information cues and interest in potential information cues placed on fish labels, packages or shelves in five European countries. A cross-sectional consumer survey was carried out in November-December 2004 in five European countries: Belgium, Denmark, the Netherlands, Poland and Spain and a sample representative for age and region within each country has been obtained. Total sample size is 4,786. The results show a high use of on-label information cues; hence, labels were found as good, and potentially market effective sources of information. Consumers were most familiar with expiry date, price, species name and weight and they felt able to derive clear quality expectations from the information these cues convey. Consumers displayed the strongest interest in an additional information cues, such as safety guarantee and a quality mark for seafood. Cross-country differences in both use and interest in fish information cues were observed.consumer, fish, label, Consumer/Household Economics, Marketing,

Alignment and Ergativity in New Indo-Aryan Languages /
No full textThe book provides an overview of the alignment patterns found in modern Indo-Aryan languages. The analysis of the patterns of case marking and agreement leads to a balanced view on the concept of ergativity and evaluates its value for typological linguistics. The book offers an extensive discussion of previous approaches to ergativity. It analyzes four Indo-Aryan languages– Asamiya, Nepali, Rajasthani and Kashmiri– on the basis of text corpora. Examples from other Indo-Aryan languages are also adduced. The book is a thorough synchronic study of alignment patterns in Indo-Aryan languages.The book provides an overview of the alignment patterns found in modern Indo-Aryan languages.

However, the former could not be located, neither at the CABI (former CIBC), nor at the IRSN. Graham (1969: 530) stated that he had seen`the types’ but he may actually have examined only the specimens at the IRSN (Graham, apparently, rarely had access to type material deposited at the CIBC or in Delucchi’s private collection). As was the case for any other type material quoted for the CIBC by Delucchi, it seemed likely that it had either remained in his private collection or at the BMNH.</p> <p> There is now strong evidence that the specimens labelled as` Habrocytus verbekei’ in fact represent the missing part of the type series of <i>milleri</i>. Delucchi (pers. comm.) never intended to describe any other <i>Habrocytus</i> than <i>milleri</i>. Most likely he just failed to replace the labels when by Verbeke’s appearance as co-author a change in naming the species became necessary. More importantly, some of the above slidemounted parts were used in the original description. Thus I was able to associate the following slides and ®gures without question: one slide`46; Habrocytus verbekei LABIUM (L) MAXILLAE ANTENNAE m’ with female antennae and mouth parts, the left antenna illustrated (p. 7, ®gure 8), one slide`50; Habrocytus verbekei ali’ with female fore wings, venation and stigma of right fore wing illustrated (p. 7, ®gures 4, 5), one slide`44; Habrocytus verbekei APPAR.
