Is Eradication of the Pinewood Nematode (Bursaphelenchus xylophilus) Likely? An Evaluation of Current Contingency Plans

The pinewood nematode (PWN) is one of the worst tree‐killing exotic pests in East‐Asian countries. The first European record of establishment in Portugal in 1999 triggered extensive surveys and contingency plans for eradication in European countries, including immediate removal of large areas of conifer host trees. Using Norway as an example, we applied a simulation model to evaluate the chance of successful eradication of a hypothetical introduction by the current contingency plan in a northern area where wilting symptoms are not expected to occur. Despite a highly variable spread of nematode infestations in space and time, the probability of successful eradication in 20 years was consistently low (mean 0.035, SE 0.02). The low success did not change significantly by varying the biological parameters in sensitivity analyses (SA), probably due to the late detection of infestations by the survey (mean 14.3 years). SA revealed a strong influence of management parameters. However, a high probability of eradication required unrealistic measures: achieving an eradication probability of 0.99 in 20 years required 10,000 survey samples per year and a host tree removal radius of 8,000 m around each detection point.     

Statistical Corrections of Invalid Correlation Matrices

Suppose estimates are available for correlations between pairs of variables but that the matrix of correlation estimates is not positive definite. In various applications, having a valid correlation matrix is important in connection with follow‐up analyses that might, for example, involve sampling from a valid distribution. We present new methods for adjusting the initial estimates to form a proper, that is, nonnegative definite, correlation matrix. These are based on constructing certain pseudo‐likelihood functions, formed by multiplying together exact or approximate likelihood contributions associated with the individual correlations. Such pseudo‐likelihoods may then be maximized over the range of proper correlation matrices. They may also be utilized to form pseudo‐posterior distributions for the unknown correlation matrix, by factoring in relevant prior information for the separate correlations. We illustrate our methods on two examples from a financial time series and genomic pathway analysis.     

Conduct Problems in Adopted and Non-adopted Adolescents and Adoption Satisfaction as a Protective Factor

The present study compared the level of conduct problems at age 17 in a large, non-clinical sample of adopted participants placed in infancy and children in non-adoptive families matched to the adoptive families on demographic characteristics. Higher levels of adolescent and parent adoption satisfaction were associated with lower levels of conduct problems. Gender by adoption status interactions were not significant. However, female adopted participants had higher levels of conduct problems than female non-adopted participants, whereas male adopted and non-adopted participants had similar levels of conduct problems. In the overall sample, differences between adopted and matched control participants on all conduct problem measures were nonsignificant.     

Balls Enough: Manliness and Legitimated Violence in Hell's Kitchen

This article presents one example of how masculinity and hierarchy are exercised through violence in organizations. It draws on the empirical data of 15 episodes from the US reality television series Hell's Kitchen, in which 15 cooks compete for the job of Chef in one of celebrity chef Gordon Ramsay's restaurants. Ramsay's task is to lead the cooks towards a hegemonic masculinity valid in the restaurant context. An important feature is the contestant's ability to deal with Ramsay's fiery temper and fits of rage. The winner is the person who succeeds in approaching Ramsay's standards in terms of culinary art and leadership qualities, which in his terminology is referred to as manliness. Ramsay's aggressive style of management is possible to recognize, explain and to a certain extent justify as a way of running a restaurant. But what if his tongue‐lashings are to be understood, not as a possible way to train skilled chefs, but instead are called violence? Gender‐oriented organizational studies stress the importance of paying attention to acts of violence in organizations rather than disregarding it as organizational culture or tradition. Using concepts and perspectives from masculinity theory and feminist studies on men's violence against women, the purpose of this article is to analyse the micro practices of how masculinity and hierarchy are exercised through violence in the restaurant environment. As will be argued, reality television can be understood, not so much as a reflection but rather as an exaggeration of real life. It can be seen as a distorting mirror that enlarges and at the same time perverts the micro practices of reality. The aim is dual; to investigate the link between masculinity and legitimated violence in organizations and to give prominence to the potential of reality television visualizing the normalization of violence in organizations.     

翻译文学经典的建构——以张谷若译《德伯家的苔丝》为例

在翻译文学经典的建构中,除了社会文化等外在因素外,译本自身的品质起着至关重要的作用。就译本品质的形成而言,译者发挥着不可替代的作用,其中译者的语言文学修养、翻译态度、翻译策略等,既是制约译本品质也是制约翻译文学经典建构的重要因素。
