Prey preference of the wolf spider,Pardosa pseudoannulata (Boesenberg et Strand)

Summary Functional responses of the wolf spider,Pardosa pseudoannulata (Boesenberg et Strand) attacking the rice brown planthopper,Nilaparvata lugens (St?l.), and the mirid predatorCyrtorhinus lividipennis Reuter were both those of Holling Type II. The attack rate was higher and handling time lower forC. lividipennis. However, when caged with the two prey, the wolf spider showed a significant preference forN. lugens at a lower prey proportion. Proportions of prey attacked were significantly different from the expected ratios of prey available as well as from the predicted preferences derived from the functional response parameters. As proportions ofN. lugens attacked changed from greater to less than expected as the proportions ofN. lugens available increased, a “reverse switch” behaviour seems to be evident.     

Local Influence Analysis for Skew-Normal Linear Mixed Models

In this article, we consider local influence analysis for the skew-normal linear mixed model (SN-LMM). As the observed data log-likelihood associated with the SN-LMM is intractable, Cook's well-known approach cannot be applied to obtain measures of local influence. Instead, we develop local influence measures following the approach of Zhu and Lee (2001 Zhu , H. , Lee , S. ( 2001 ). Local influence for incomplete-data models . J. Roy. Statist. Soc. Ser. B 63 : 111 – 126 .[Crossref] , [Google Scholar]). This approach is based on the use of an EM-type algorithm and is measurement invariant under reparametrizations. Four specific perturbation schemes are discussed. Results obtained for a simulated data set and a real data set are reported, illustrating the usefulness of the proposed methodology.     

Promoting workplace‐based training to fight youth unemployment in three EU countries: Different strategies,different results?

During the economic crisis, youth unemployment grew exponentially in many European countries. It was argued that countries with a high level of firm involvement in the provision of initial vocational training were better equipped to address this problem. Boosting workplace‐based training was therefore seen as the right strategy to tackle unemployment. Using Denmark, Spain and the UK as case studies, this article analyses how countries with different skill formation systems have improved this type of training. While the UK reinforced the voluntaristic character of its training regime, Denmark improved the quality of its vocational education, and Spain made reforms to the training and apprenticeship contract. Interestingly, the countries achieved different results. To explain this divergence, it is argued that while the reforms made in the UK and Denmark were compatible with the national institutions and coordination mechanisms, this was not the case in Spain, where reforms were implemented in a non‐complementary way. Key Practitioner Message:

• After the economic crisis it was argued that countries with a high level of firm involvement in the provision of initial VET were better equipped to fight youth unemployment.
• The study analysed how countries with different skill formation systems improved this type of training and assessed their relative success.
• The article shows that when implementing reforms policy makers must take into account the institutions and mechanisms of coordination that prevail in each country. Otherwise, reforms may be unsuccessful.

     

Freud s Sisters A Fantasia on a Photograph

This psychoanalytically based imaginative inquiry into the role of Freud's sisters in shaping the meanings of Femaleness and gender difference for Freud starts from the author's study of a photograph in the Library of Congress Freud exhibit, “Portrait of the Jakob Freud Family ca. 1876,” which shows Sigmund Freud, age 20, with his live then adolescent sisters. Freud's Dream of the Botanical monograph, especially as reconsidered by Didier Anzieu, is used as a window into Freud's early childhood relations with his sisters and the registration of gender difference in his psychic reality. A peculiarity in the photograph in the presentation of Freud's half-brother, Emmanuel, leads the author's reverie to another dream of Freud's, the “nonvixit dream.” especially as reconsidered by Didier Anzieu and by Max Schur. The non-vixit dream is thought to bear traces of Freud's experience of the death of his infant brother Julius. New suggestions are made with regard to Freud's difficulties with depressive-position anxieties in relation to his mother; it is suggested that these difficulties led to his concept of girls' genitals as “castrated” becoming dominant over another stratum of psychic experience in which girls' genitals, and femininity, were viewed with erotic wonder as intact in their own right. This idea is linked with Freud's difficulties in construing woman as subject.     

The visual construction of “the people” and “proximity to the people” on the online platforms of the National Front and Swiss People’s Party

The article explores and compares how the online communication of the National Front (FN) and Swiss People’s Party (SVP) visualise and define “the people” and “proximity to the people” in the wake of the Swiss federal elections and the French regional elections in 2015. Considerations based on netnography, discourse analysis and visual culture studies inform the corpus-based approach of the study. The results of the analysis show significant differences in the way each party represents itself: the FN visually frames itself as a party for the people whereas the SVP portrays itself as a party of the people. This is due to distinct ways of depicting the relation between party representatives and citizens as well as the “in-group”.     

Bayesian generalizations of the integer-valued autoregressive model

We develop two Bayesian generalizations of the Poisson integer-valued autoregressive model. The AdINAR(1) model accounts for overdispersed data by means of an innovation process whose marginal distributions are finite mixtures, while the DP-INAR(1) model is a hierarchical extension involving a Dirichlet process, which is capable of modeling a latent pattern of heterogeneity in the distribution of the innovations rates. The probabilistic forecasting capabilities of both models are put to test in the analysis of crime data in Pittsburgh, with favorable results.     

Physical consequences of falls in the elderly: a literature review from 1995 to 2010

In the last decade, population ageing has been registered as a global phenomenon. A relation exists between falling and ageing, since falling frequency increases significantly with age. In fact, one in three older adult falls annually. Although ageing is generically associated with decrease and degeneration of psychological and physical functions, it is still not common for the correct identification of risk factors to lead to a clinical prognosis of the elder being in risk of falling. Therefore, the goal of this review article is to identify, categorise and analyse typical ageing and fall factors mentioned in the literature as well as to quantify the number of times they were referenced. The research considered hundreds of publications, but analysis was then restricted to the 87 most pertinent articles written in English and published in journals or scientific magazines between 1995 and 2010. We concluded that falls among older adults can be characterised by the following: anatomic characteristics and physiological consequences of ageing; the pathologies that induce falls, which can be neurological, musculoskeletal, cardiovascular and other diseases; causes and risk factors of falls that can be behavioural, biological, environmental or socio-economic; type of physical consequences of falls, including fractures, bruises, injuries or other physical consequences; and strategies to prevent, mitigate or rehabilitate, which can be of a physical, environmental or behavioural nature.     

Ariadne’s thread: Cape Verdean women in transnational webs

This article is about Cape Verdean women who make a living through engaging in regular transnational petty trade. They buy consumer goods in West African countries, in Portugal and elsewhere in Europe, in Brazil and in the USA, to sell back in Cape Verde, either in open‐air markets or in their own shops. Women perform most of this kind of trade and they operate on the border between the formal and informal economies. Drawing on interview material, the article shows how their self‐presentation as autonomous self‐reliant economic agents relates to gender and family roles and to a strategic balance between personal freedom and embeddedness in multi‐territorialized networks.
