Integrating constructive feedback in personalised e-learning
When using e-learning material some students progress readily, others have difficulties. In a traditional classroom the teacher would identify those with difficulties and direct them to additional resources. This support is not easily available within e-learning. A new approach to providing constructive feedback is developed that will enable an e-learning system to identify areas of weakness and provide guidance on further study. The approach is based on the tagging of learning material with appropriate keywords that indicate the contents. Thus if a student performs poorly on an assessment on topic X, there is a need to suggest further study of X and participation in activities related to X such as forums. As well as supporting the learner this type of constructive feedback can also inform other stakeholders. For example a tutor can monitor the progress of a cohort; an instructional designer can monitor the quality of learning objects in facilitating the appropriate knowledge across many learners

Bezerromycetales and Wiesneriomycetales ord. nov. (class Dothideomycetes), with two novel genera to accommodate endophytic fungi from Brazilian cactus
During a survey of endophytic fungi from the cactus Tacinga inamoena in a Brazilian tropical
dry forest (Caatinga) some undescribed ascomycetous fungi were isolated. These fungi are
characterized by superficial and immersed, globose to subglobose, smooth or hairy
ascomata, bitunicate asci, and muriformly septate, ellipsoidal ascospores. Multigene
phylogenetic analyses using sequences from partial ITS, SSU and LSU nrDNA and the
translation elongation factor 1-alpha gene (tef1) demonstrated a monophyletic clade
accommodating these endophytic fungi in the class Dothideomycetes, closely related to the
order Tubeufiales. Based on morphological features and phylogenetic analyses, these fungi
could not be placed in the order Tubeufiales, in the new order Wiesneriomycetales, or any
other known genus in the class Dothideomycetes. Thus, two new genera (Bezerromyces,
with B. brasiliensis and B. pernambucoensis, and Xiliomyces with X. brasiliensis), a new
family (Bezerromycetaceae) and a new order (Bezerromycetales) are introduced to
accommodate these novel taxa. Our phylogenetic analyses also demonstrated that the clade
accommodating Wiesneriomycetaceae represents a new order, here introduced as
