    The Frost Multidimensional Perfectionism Scale revisited: More perfect with four (instead of six) dimensions

    The Frost Multidimensional Perfectionism Scale (FMPS; Frost, Marten, Lahart & Rosenblate, 1990) provides six subscales for a multidimensional assessment of perfectionism: Concern over Mistakes (CM), Personal Standards (PS), Parental Expectations (PE), Parental Criticism (PC), Doubts about actions (D), and Organization (O). Despite its increasing popularity in personality and clinical research, the FMPS has also drawn some criticism for its factorial instability across samples. The present article argues that this instability may be due to an overextraction of components. Whereas all previous analyses presented six-factor solutions for the FMPS items, a reanalysis with Horn's parallel analysis suggested only four or five underlying factors. To investigate the nature of these factors, item responses from N = 243 participants were subjected to principal component analysis. Again, parallel analysis retained only four components. Varimax rotation replicated PS and O as separate factors, whereas combining CM with D as well as PE with PC. Consequently, the present article suggests a reduction to four (instead of six) FMPS subscales. Differential correlations with anxiety, depression, parental representations and action tendencies underscore the advantage of this solution

    Integrated disease management using environmental control in tea fields

    No full text
    The occurrence of plant disease depends on interactions between the host plant, a pathogen, and the environment in a dynamic called "the disease triangle". Bacterial shoot blight (BSB) disease, caused by _Pseudomonas syringae_ pv. _theae_ (_Pst_), is a major bacterial disease of tea plants in Japan and substantially reduces tea productivity. BSB mainly occurs in the low-temperature season, and lesion formation by _Pst_ is enhanced by both low temperature and the presence of ice nucleation-active _Xanthomonas campestris_ (INAX), which catalyses ice formation at -2 to -4^o^C and is frequently co-isolated with _Pst_ from tea plants^5^. Low temperature is thus the most important environmental factor to influence the incident; however, the effects of environmental controls in fields on the occurrence of the disease are poorly understood. Here we show that the natural incidence of BSB in the field is closely related to low temperatures in late autumn. Frost protection in late autumn, which protected tea plants against extremely low temperatures, significantly decreased the incidence of BSB, and frost protection combined with bactericide application held the incident under the economic threshold level. Our data indicate that environmental control in the field based on microbial interactions in the host offers a new strategy for plant disease control using integrated plant disease management based on the disease triangle concept

    Transcription of reference genes used for quantitative RT-PCR in Atlantic salmon is affected by viral infection

    No full text
    Abstract Relative quantification using RT-qPCR is a widely used method for transcription profiling. Transcript levels of target genes in fish after experimental infection is often reported without documentation of stably transcribed reference genes. We present results demonstrating that transcription of typically used reference genes in Atlantic salmon is not stable during experimental infection with salmon pancreas disease virus (SPDV). Transcript levels 0 to 6 weeks after challenge revealed statistically significant changes between time-points that corresponded with a peak in viral load 3 weeks after challenge. The results emphasize the need for thorough method validation prior to transcriptional studies during viral infections.</p

    Process Migration in FROST

    No full text
    FROST is a distributed heterogeneous calculation platform first described in ``FROST - A Distributed Heterogeneous Calculation Platform''''. It provides an API that allows a user to create assignments which are distributed and calculated on a number of computers. In this project we have chosen to improve the dynamic load balancing scheme of the FROST system by implementing process migration. We do this in order to improve the performance of the system as processes can be moved from nodes that are heavily loaded onto nodes that are less loaded during execution. We have analyzed the problem of process migration and have decided on a solution using checkpoints as a means of performing process migration. The chosen solution has been designed and parts of the design has been implemented. During the design phase we have been very aware that the performance aspects of FROST should not become worse after the introduction of process migration as it would remove the reason for using the feature. We have tested the system with regard to overhead, performance and the behavior of the migration policies. The tests show that the overhead with regard to the process migration features is fairly small compared to what they offer. In addition the performance tests and the policy tests showed that the system performs well after the introduction of process migration. We do conclude, however, that in order to obtain even better performance it should be considered to introduce migration points as a tool as well
