Representativity error for temperature and humidity using the Met Office high-resolution model

The observation-error covariance matrix used in data assimilation contains contributions from instrument errors, representativity errors and errors introduced by the approximated observation operator. Forward model errors arise when the observation operator does not correctly model the observations or when observations can resolve spatial scales that the model cannot. Previous work to estimate the observation-error covariance matrix for particular observing instruments has shown that it contains signifcant correlations. In particular, correlations for humidity data are more significant than those for temperature. However it is not known what proportion of these correlations can be attributed to the representativity errors. In this article we apply an existing method for calculating representativity error, previously applied to an idealised system, to NWP data. We calculate horizontal errors of representativity for temperature and humidity using data from the Met Office high-resolution UK variable resolution model. Our results show that errors of representativity are correlated and more significant for specific humidity than temperature. We also find that representativity error varies with height. This suggests that the assimilation scheme may be improved if these errors are explicitly included in a data assimilation scheme.

Biology and reproductive behavior of Murgantia histrionica (Heteroptera: Pentatomidae)

Life history parameters and reproductive behaviors of the harlequin bug, Murgantia histrionica Hahn (Heteroptera: Pentatomidae), were determined. Total developmental time from egg to adult was ≈48 d. After a sexual maturation period of ≈7 d, both sexes mated repeatedly, with females laying multiple egg masses of 12 eggs at intervals of 3 d. Adult females lived an average of 41 d, whereas adult males lived an average of 25 d. Courtship and copulation activities peaked in the middle of the photophase. In mating experiments in which mixed sex pairs of virgin and previously mated bugs were combined in all possible combinations, the durations of courtship and copulation by virgin males were significantly longer with both virgin and previously mated females than the same behaviors for previously mated males. When given a choice between a virgin or previously mated female, previously mated males preferred to mate with virgin females, whereas virgin males showed no preference for virgin over previously mated females. Analyses of mating behaviors with ethograms and behavioral transition matrices suggested that a primary reason for failure to copulate by virgin males was the incorrect rotation of their pygophores to the copulation position, so that successful alignment of the genitalia could not occur.

Those Essex girls: the lives and letters of Lettice Knollys, Penelope Rich, Dorothy Perrott Percy, and Frances Walsingham

This essay examines the lives and letters of four of the most influential women at the court of Queen Elizabeth I: Lettice Knollys her daughters Penelope Rich and Dorothy Perrott Percy and her daughter-in-law Frances Walsingham, all of whom lived scandalous but powerful lives.

Copyright exceptions and contract in the UK: the impact of recent amendments

In June and October 2014 a number of amendments to the Copyright, Designs and Patents Act 1988 came into effect, introducing new copyright exceptions and amending several existing exceptions. Whilst following recent judicial review the private copying exception has been quashed, many of the remaining new exceptions significantly alter the relationship between copyright exceptions and contract, making contractual terms unenforceable where those terms restrict users from taking advantage of an exception. This paper explores the rationale for the UK amendments and considers whether the changes, as implemented, prevent rightsholders from contracting out of exceptions and whether they increase the clarity of the copyright system.

Taste components of Sherry wines

Sherry wine has characteristic taste and aroma, different from other wine-based alcoholic beverages. This paper reports a study of the non-volatile, low-molecular weight compounds found in sherry and related alcoholic beverages that may contribute to taste. Compounds analysed included free amino acids, organic acids, sugars and small peptides (linear and cyclic). A series of seven diketopiperazines (cyclic dipeptides) namely, cyclo(Leu-Leu), cyclo(Pro-Leu), cyclo(Pro-Ile), cyclo(Pro-Met), cyclo( Pro-Val), cyclo(Pro-Pro) and cyclo(Val-Ala) were identified for the first time in sherry. Although traces were found in some other alcoholic beverages, levels were low compared with sherry. The base wine used in the sherry production had only traces of diketopiperazines, indicating that the casking stage of sherry production might be responsible for their formation.

Effect of asparaginase on flavour formation in roasted coffee

The use of asparaginase, an enzyme that hydrolyses the acrylamide precursor asparagine into aspartic acid and ammonia, is seen as a promising procedure to mitigate the formation of the potential human carcinogen acrylamide in food products, without compromising desirable sensory qualities. This study examines the effect of asparaginase treatment on the asparagine and aspartic acid content of green coffee beans prior to roasting as well as the impact on the formation of acrylamide and thermally generated aroma compounds in roasted coffee

Josephine: desire, ambition, Napoleon

Biography of Josephine Bonaparte. The incredible rise and unbelievable fall of Josephine, a mistress, courtesan and Revolutionary heroine whose energy and ambition has often been overshadowed by Napoleon’s military might. Historian Kate Williams, author of Becoming Queen, tells Josephine’s searing story of sexual obsession, politics and surviving as a woman in a man’s world. Abandoned in Paris by her aristocratic husband, Josephine's future did not look promising. But while her friends and contemporaries were sent to the guillotine during the Terror that followed the Revolution, she survived prison and emerged as the doyenne of a wildly debauched party scene, surprising everybody when she encouraged the advances of a short, marginalised Corsican soldier, six years her junior. Josephine, the fabulous hostess and skilled diplomat, was the perfect consort to the ambitious but obnoxious Napoleon. With her by his side, he became the greatest man in Europe, the Supreme Emperor; and she amassed a jewellery box with more diamonds than Marie Antoinette’s. But as his fame grew, Napoleon became increasingly obsessed with his need for an heir and irritated with Josephine’s extravagant spending. The woman who had enchanted France became desperate and jealous. Until, a divorcee aged forty-seven, she was forced to watch from the sidelines as Napoleon and his young bride produced a child.

Mating system and exclusive postzygotic paternal care in a Neotropical harvestman (Arachnida: Opiliones)

This study tests predictions of the hypothesis of evolution of paternal care via sexual selection by using the Neotropical harvestman Pseudopucrolia sp. as the model organism. Females use natural cavities in roadside banks as nesting sites, which are defended by males against other males. Females leave the nests after oviposition, and all postzygotic parental care is accomplished by males, which protect the eggs and nymphs from predators. We provided artificial mud nests to individuals in the laboratory and conducted observations on the reproduction of the species. Male reproductive success was directly related to nest ownership time: the longer a male held a nest, the higher his chances of obtaining copulations. All males that succeeded in mating and obtaining one clutch eventually mated with additional females that added eggs to the clutch. Thus, desirable males were not limited to monogamy by paternal care. Experimental manipulations demonstrated that guarding males were more attractive to females than were nonguarding males and also that males guarded unrelated eggs. Finally, we found that females and nonguarding males spent more time foraging than guarding males. We use our data to contrast hypotheses on the origin and maintenance of paternal care and to provide a critical assessment of the hypothesis of the evolution of paternal care via sexual selection.

”He looked at me ... My God. His eyes were eyes to die for.” : A Feminist Theological Reading of Carol Ann Duffy’s The World’s Wife

Most approaches to Duffy’s work have been a feminist reading of poetry, focusing on the portrayal of women within the theoretical framework of feminism. However, little attention has been paid to the religious elements in Duffy’s work, something that Duffy herself has recognized. This essay will therefore focus on the centrality of religion in Duffy’s work, and will argue that her poems constitute an arena where religion is redefined and female experience and theology are reconciled. The poems under focus, “Delilah”, “Salome”, “Pilate’s wife”, “Pope Joan”, “Mrs Lazarous” and “Queen Herod” are examined in two separate sections: their portrayal of love and sexuality, and their portrayal of motherhood respectively, within the theoretical framework of feminist theology.

Kung slår dam : våldsforskningsmetodologi i ett våldsamt jämställt Sverige

King captures queen. Methodology in research on violence in violently equal Sweden Research and debate on violence against women in a Swedish context is here discussed from a perspective that focuses on the different understandings and epistemological claims behind existing positions. I crystallize a dominant perspective on violence, centred around fragmentation/deviance, and a challenging feminist understanding, centred around coherence/normality. I relate these understandings to a wider set of methodological choices and epistemological claims within research on violence against women, captured in what I call a discourse on partner violence (fragmentation) and a feminist discourse on men’s violence against women (coherence). The article also examines the reactions, in media and academic life, that a quantitative study on men’s violence against women in Sweden provoked, Captured queen, men’s violence against women in equal Sweden. A prevalence study (Lundgren et al 2001). By applying a coherent methodological approach, stemming from the feminist discourse on violence against women, the study seems to have placed itself outside what was comprehensible for many voices in the debate (from media and the academic field). I discuss the hostile reactions the study aroused, in relation to its methodology and the above presented conflicting understandings that occupy the research field “violence against women”.

Gli studi italiani sulla regina Cristina di Svezia negli ultimi cinquant'anni

Queen Christina of Sweden (1626-1689)) is probably the most important individual to directly link the cultures of Sweden and Italy, and thus fascinate scholars over the last four centuries. In the last fifty years, research on and interest in this monarch has been particularly intense. This has led to current international scientific debate concerning all the different cultural expressions in which Queen Cristina was particularly involved. However, until now there has been lacking a comprehensive work to illustrate the development of scientific research in Italian on Queen Christina. This article, therefore, without claiming to be exhaustive, aims to fill this gap by identifying the main direction of current research. The article, after briefly introducing previous works (both Italian and Swedish), demonstrates how the first major renaissance of international studies on Queen Cristina took place in Sweden in the early 1960s. Even more important was the subsequent turning point in 1989, when the tercentenary of the death of Queen Christina was celebrated and the Azzolino Collection at the Biblioteca Comunale in Jesi was opened. The article focuses on the studies in Italian during this latter period. To make the exposition more organic and, importantly, more accessible to those readers interested in only one particular aspect of the scientific studies about Queen Christina, the studies in Italian since 1689 are divided into different subject areas.
