Constructive alignment in the built environment: enhancing teaching in line with graduate outcomes

The paper examines the manner in which to review an undergraduate degree in construction management using a top-down approach known as “Constructive Alignment”. The research addresses not only the perceived teaching problems, but it also discusses the methods used to rejuvenate the course in a manner that aligns with the graduate outcomes. However, it was also clear that teaching staff were not especially aware of the need to address the course learning outcomes. This highlighted the need for teaching staff to be involved in a process of constructive alignment to embed the course learning outcomes within their subjects, while also addressing the teaching issues involved with assessment. This process provided an opportunity to determine the incremental skill and knowledge development, both within the subjects, as well as between subjects across the course. The paper concludes with the production of a conceptual framework, which can be used to assist with the alignment of professional standards, course outcomes and graduate attributes into a discipline-specific degree program

Tertiary architecture and construction management students\u27 academic performance: role of demographic variables

This study presents an account of how different demographic variables affect students’ academic performance. The studied sample comprises a cohort of 133 Architecture and Construction Management (ACM) students in a third-year unit allocated to construction methodology and structural knowledge required for high-rise construction. Data is collected for these students studying at the School of Architecture and Built Environment at Deakin University (A+B). Outcomes of group and individual task (exam) are analysed deploying statistical methods. The findings show no significant difference between students coming to university from Year-12-to-and those that come from the vocational education sector. Furthermore, the findings indicate significant discrepancy in terms of performance amongst the students enrolled in construction management course with double-degree and architecture students. Additionally, the study reveals that female students outperform male students in individual tasks. The findings could be applicable to redesigning assessments as well as planning of prerequisite units in the studied curricula

Characterizing the pathotype of neonatal meningitis causing <i>Escherichia coli</i> (NMEC)

Background Neonatal meningitis-causing Escherichia coli (NMEC) is the predominant Gram-negative bacterial pathogen associated with meningitis in newborn infants. High levels of heterogeneity and diversity have been observed in the repertoire of virulence traits and other characteristics among strains of NMEC making it difficult to define the NMEC pathotype. The objective of the present study was to identify genotypic and phenotypic characteristics of NMEC that can be used to distinguish them from commensal E. coli. Methods A total of 53 isolates of NMEC obtained from neonates with meningitis and 48 isolates of fecal E. coli obtained from healthy individuals (HFEC) were comparatively evaluated using five phenotypic (serotyping, serum bactericidal assay, biofilm assay, antimicorbial susceptibility testing, and in vitro cell invasion assay) and three genotypic (phylogrouping, virulence genotyping, and pulsed-field gel electrophoresis) methods. Results A majority (67.92 %) of NMEC belonged to B2 phylogenetic group whereas 59 % of HFEC belonged to groups A and D. Serotyping revealed that the most common O and H types present in NMEC tested were O1 (15 %), O8 (11.3 %), O18 (13.2 %), and H7 (25.3 %). In contrast, none of the HFEC tested belonged to O1 or O18 serogroups. The most common serogroup identified in HFEC was O8 (6.25 %). The virulence genotyping reflected that more than 70 % of NMEC carried kpsII, K1, neuC, iucC, sitA, and vat genes with only less than 27 % of HFEC possessing these genes. All NMEC and 79 % of HFEC tested were able to invade human cerebral microvascular endothelial cells. No statistically significant difference was observed in the serum resistance phenotype between NMEC and HFEC. The NMEC strains demonstrated a greater ability to form biofilms in Luria Bertani broth medium than did HFEC (79.2 % vs 39.9 %). Conclusion The results of our study demonstrated that virulence genotyping and phylogrouping may assist in defining the potential NMEC pathotype

Full Sequence and Comparative Analysis of the Plasmid pAPEC-1 of Avian Pathogenic E. coli χ7122 (O78∶K80∶H9)

(APEC), are very diverse. They cause a complex of diseases in Human, animals, and birds. Even though large plasmids are often associated with the virulence of ExPEC, their characterization is still in its infancy., are also present in the sequence of pAPEC-1. The comparison of the pAPEC-1 sequence with the two available plasmid sequences reveals more gene loss and reorganization than previously appreciated. The presence of pAPEC-1-associated genes is assessed in human ExPEC by PCR. Many patterns of association between genes are found.The pathotype typical of pAPEC-1 was present in some human strains, which indicates a horizontal transfer between strains and the zoonotic risk of APEC strains. ColV plasmids could have common virulence genes that could be acquired by transposition, without sharing genes of plasmid function

The bHLH transcription factor SPATULA enables cytokinin signaling, and both activate auxin biosynthesis and transport genes at the medial domain of the gynoecium

[EN] Fruits and seeds are the major food source on earth. Both derive from the gynoecium and, therefore, it is crucial to understand the mechanisms that guide the development of this organ of angiosperm species. In Arabidopsis, the gynoecium is composed of two congenitally fused carpels, where two domains: medial and lateral, can be distinguished. The medial domain includes the carpel margin meristem (CMM) that is key for the production of the internal tissues involved in fertilization, such as septum, ovules, and transmitting tract. Interestingly, the medial domain shows a high cytokinin signaling output, in contrast to the lateral domain, where it is hardly detected. While it is known that cytokinin provides meristematic properties, understanding on the mechanisms that underlie the cytokinin signaling pattern in the young gynoecium is lacking. Moreover, in other tissues, the cytokinin pathway is often connected to the auxin pathway, but we also lack knowledge about these connections in the young gynoecium. Our results reveal that cytokinin signaling, that can provide meristematic properties required for CMM activity and growth, is enabled by the transcription factor SPATULA (SPT) in the medial domain. Meanwhile, cytokinin signaling is confined to the medial domain by the cytokinin response repressor ARABIDOPSIS HISTIDINE PHOSPHOTRANSFERASE 6 (AHP6), and perhaps by ARR16 (a type-A ARR) as well, both present in the lateral domains (presumptive valves) of the developing gynoecia. Moreover, SPT and cytokinin, probably together, promote the expression of the auxin biosynthetic gene TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS 1 (TAA1) and the gene encoding the auxin efflux transporter PIN-FORMED 3 (PIN3), likely creating auxin drainage important for gynoecium growth. This study provides novel insights in the spatiotemporal determination of the cytokinin signaling pattern and its connection to the auxin pathway in the young gynoecium.IRO, VMZM, HHU and PLS were supported by the Mexican National Council of Science and Technology (CONACyT) with a PhD fellowship (210085, 210100, 243380 and 219883, respectively).

Student participation in professional organisations: the need for innovation

Professional organisations in construction management and builtenvironment list many benefits of membership, including professionaldevelopment and engagement with fellow professionals. However,despite free membership for students, their membership and retention isgenerally low and it is important for the future of professionalorganisations to determine reasons for this disinterest. Do currentstudents understand the benefits of professional organisations and placeany value on membership? This paper presents the findings of a researchproject to better understand why recruitment of students and their activeparticipation in professional organisations is low. A questionnaire surveywas conducted across the students of the degrees of constructionmanagement in Deakin University to obtain the evaluations of themembership, while interviews were undertaken with representatives ofprofessional organisations to determine the alignment between theparties. Student expectations of membership were shown to be amismatch with the stated benefits offered by the professionalorganisations, or at least with how these benefits are communicated.Possible improvements are suggested to ensure that, in this era of instantcommunications and access to information, professional organisationsinnovate to remain relevant to the future leaders of their industry

Development of a framework for flood mitigation in Fiji

244 DEVELOPMENT OF A FRAMEWORK FOR FLOOD MITIGATION IN FIJI Mingyuan Guo1, Argaw Gurmu2 and Linda Tivendale3 ABSTRACT A large portion of infrastructure was flooded by water running off pavements or overflowing from the drainage systems in Fiji. The main objectives of this study are to identify the most suitable drainage management solution to reduce the overflow of the drainage system in Fiji, and to develop a framework of drainage management systems. The literature review was conducted to identify various drainage systems used to mitigate flooding around the world. After the review, the characteristics of Fiji such as climate pattern, location and soil type were analysed in the case study section. Secondary data which was obtained from Australia, Norway, the Netherlands, the U.S., Korea, and China were used in the research. The characteristics of Fiji were then mapped to other countries and a scoring system was created to analyse the suitability of different flood mitigation techniques in Fiji. Finally, multiple flood management strategies were proposed, and a drainage management framework for flood mitigation was developed

Teaching collaboration in tertiary BIM education: A review and analysis

Building Information Modelling (BIM) is inherently a team-based activity and possessing the Knowledge, Skills, and Abilities (KSAs) to collaborate across various disciplines and organisations are central for BIM-ready graduates. There is, nevertheless, no systematic attempt to analyse the current approaches to teaching collaboration KSAs across tertiary education institutions. This study is an attempt to provide an account of the current approaches taken by leading universities for training and educating collaboration, as a part of their BIM education programs. To this end, 63 articles on BIM education were identified, of which 18 were used to extract their practices to teaching collaboration. The content analysis of these studies revealed that the practices identified can be presented under 4 broad categories including Instructional approach, Prerequisites, Marking and evaluation, and Feedback, in which each category has various sub-categories. As the first in its kind, the present study provides an analysis and synthesis of the best practices for teaching educating collaboration, and therefore, assists educators and curriculum builders in integrating collaboration KSAs into BIM education in construction-related curricula
