Taxonomy and phylogeny of the genus Mycosphaerella and its anamorphs
No full textHistorically plant pathogenic species of Mycosphaerella have been regarded as host-specific, though this hypothesys has proven difficult to test largely due to the inavailability of fungal cultures. During the course of the past 20 years a concerted effort has been made to collect these fungi, and devise methods to cultivate them. Based on subsequent DNA sequence analyses the majority of these species were revealed to be host-specific, though some were not, suggesting that no general rule can be applied. Furthermore, analysis of recent molecular data revealed Mycosphaerella to be poly- and paraphyletic. Teleomorph morphology was shown to be too narrowly defined in some cases, and again too widely in others. Mycosphaerella and Teratosphaeria as presently circumscribed represent numerous different genera, many of which can be recognised based on the morphology of their 30 odd associated anamorph genera. Although Mycosphaerella is generally accepted to represent one of the largest genera of ascomycetous fungi, these data suggest that this is incorrect, and that Mycosphaerella should be restricted to taxa linked to Ramularia anamorphs. Furthermore, other anamorph form genera with Mycosphaerella-like teleomorphs appear to represent genera in their own right
Advancing the roll-out of energy networks by embedding cost differentiation in modeling approaches which minimize assessed construction costs
No full textThis thesis aims to be a contribution to the roll-out of new energy networks by presenting and discussing ways to minimize assessed construction costs associated with these networks. It does this by providing an extension of already existing methods to estimate building costs.Energy and IndustryTechnology, Policy and Managemen
Assessing the Maturity of Public Construction Client Organisations
No full textThe construction sector is changing, and commissioning organisations have to rethink the way they approach the market. This is especially important for client organisations operating in the public domain, because of their role as change agent in the sector and their social responsibilities. The ‘Public Commissioning Maturity Model’ (PCMM), first presented in 2014, was created to raise awareness amount construction clients’ organisations to the range and width of their commissioning task. It provides a means to elicit discussion on the current and desired state of the organisation’s competences, thereby supporting these organisations in further professionalization. As a result of sixworkshop-based discussion sessions and five panel discussions, the value of the model was determined. In this paper, the validation path of the model in practice is described. The findings resulted in changes to improve the usability of the model for the construction sector, as well as alterations to increase the understanding of the model for workshop participants. Adjustments regarding stylistic issues and elements in the maturity model and supporting materials were also made. Applying the PCMM has proven to enableassessment of the current and desired organisational performance on different aspects of public commissioning by eliciting discussion and raising awareness. It is however not constituted for numerical ranking, sector-wide monitoring or benchmarking purposes, while these needs also exist among client organisations. Furthermore, it was found that the model is less suitable for organisations in the middle of a comprehensive change process.Public Commissionin
Safeguarding public values by project-based construction clients: Leads for future research
No full textIn an environment with large interdependencies like the construction industry, projectbased public construction organisations are challenged to seek for 'new' ways to safeguard public values and project outcomes. Public bodies increasingly depend on private parties to achieve public values. Hence, due to the character of their tasks, they remain socialpolitically responsible. In order to find leads for future research into safeguarding public values by construction clients, an explorative literature study was conducted. The fields of institutional logics, public organisation science and public value management were used to gain insights in relevant multi-level organisational concepts considering the meaning of public values in the daily practice of public clients. Hybridity was found as characteristic of public-private partnerships. Furthermore, the management of institutional complexity as a central task for public construction clients implies the importance of monitoring ambidexterity and accountability. Future research into the understanding of safeguarding public values at all levels of public construction clients must centralise these concepts in order to contribute to the professionalization of public construction clients.Public Commissionin

The Actors' Perceptions and Expectations of their Roles in BIM-based Collaboration
No full textThe inter-organisational collaboration with Building Information Modelling (BIM) is one of the hottest topics in construction sector nowadays. The implementation of BIM is a complex inter-organisational process, and the sharing of information among numerous actors from multi-disciplinary backgrounds may affect the actors’ role perception and performance. This study offers insights into the BIM roles of various actors by analysing a BIM-based project carried out by an integrated partnership across many tiers. The analysis identified inconsistencies between the actors' perceptions and their partners’ expectations of their BIM roles. Inconsistencies in BIM roles were more related to soft rather than hard (domain- or technical) skills. Mismatches were found in the architect's role, as it was deemed necessary to be more domain- and BIM-related, contrary to their perceptions. Likewise, the suppliers' role called for an enhanced BIM orientation. The paper concludes with set of suggestions for increasing the joint responsibility and supporting the multi-actor collaboration.Design & Construction ManagementSustainable Housing Transformatio
Inheritance of resistance traits to African stem borer in grain sorghum
No full textThe African stem borer ( Busseola fusca [Fuller]) is an important
insect pest of cereals, mainly maize, sorghum and millets. The pest
causes up to 80% reduction in grain yield, depending on the pest
population in the field, cultivar and the management practices
employed. This reduction in yield translates into food insecurity,
especially in semi-arid lands (ASALs) where sorghum is cultivated by
small holder farmers. This study investigated the inheritance of
resistance traits to the African stem borers in grain sorghum in Kenya.
The experimental material consisted of seventeen sorghum lines with
varying levels of resistance to the African stem borer. The mating
design employed was North Calorina Design 2, where 15 sorghum lines
were used as females on two males. The crosses were evaluated in two
seasons at University of Embu farm in 2011/2012 short and long seasons
replicated twice. Artificial infestation with African stem borer
neonates was done 30 days after planting using a camel brush. Data
collected included stem borer damage and agro-morphological traits.
Genetic analyses were performed using a line x tester method using
Genstat statistical software. It was found that both additive and
non-additive gene effects were important in conditioning resistance
traits to the African stem borer. This implies that expression of high
leaf glossiness, plant vigour and bloom waxiness in F1 hybrids is
conditioned by additive genes and these traits can be used as
morphological markers to select for resistance to the borer in sorghum.
ICSB 464 x ICSB 473 was the best combiner for stem borer resistance and
grain yield. Parents ICSA 464, ICSB 464 and ICSB 474, were among the
good combiners for resistance to the stem borer. These parents can be
utilised in developing superior sorghum hybrids resistant to the insect
pest.Le foreur africain de tiges ( Busseola fusca [Fuller]) est un insecte
