The increased incidences of academic misconduct in universities are compromising the reputation of higher education in Australia and increasing the work of academics responsible for the delivery of quality learning outcomes to students. Confronted with increasing instances of academic dishonesty in university classrooms, universities play a pivotal role in ensuring their academic staff are well-equipped with academic integrity knowledge. It is therefore important to understand academic staff perspectives about the training their workplaces could provide them on academic integrity. Specifically, this (...) qualitative case study explores the opinions and perceptions of sessional or casual university academic staff on what content they would like to know about academic integrity, and how this knowledge could best be delivered to them. The study found that participants were genuinely interested in furthering their understanding of academic integrity issues, particularly in the areas of contract cheating, effective use of plagiarism detection tools, and developing a toolkit of skills that they could use to detect and deter plagiarism. In terms of the delivery of academic integrity training programs, webinars and orientation sessions were suggested as effective delivery mechanisms. Imparting knowledge about the content areas through the identified delivery mechanisms could enhance teaching faculty’s understanding of student academic dishonesty and how to curb this behaviour proactively.

The construction of theoretical models in biology, situated at the cross-roads of biology, mathematics and computer science, often leads to a tool as final product. Its genesis can be named Infogenesis. The procedure of the resolution of theoretical problems is analyzed on examples of practical purposes taken from plant biology.The first example deals with mineral plant nutrition, explaining a way to go from theoretical ionic balances to the experimental realization of nutritional solutions with macro-element components.

Topological developmental models with local (position of internodes) and global (branch lengths) characteristics are proposed to investigate the relationships between fundamental branching patterns of plants such as acrotony, mesotony, and basitony, including the coincidence of different patterns on the same plant. Modification of the basic acrotony during the development by means of, (1) the final expected main axis length results in either basitony or an extension of acrotony over a shortened main axis, (2) the final expected lateral branch length yields (...) either lateral unlimited sympodial branching or the absence of proximal branches. Combinations of these schemes can have variable quantitative expressions on main and lateral axes.As applications, progressive morphological changes introduced by monotonic variations of parameter values give an insight into the relationships between determinate and indeterminate growth, using Lycopersicon as an example. - A theoretical framework is proposed as a possible aid for formalizing plant typology.

A determined division wall positioning in each plant cell with respect to the last formed division wall leads to autoreproductive configurations which can simulate plant-like meristems as such with 2/5 phyllotactic patterns. L-map systems are used to generate the corresponding topological wall nets. But in these patterns cells are not six-sided as mostly found in layers. It is shown that wall staggering cannot be a determinate device of the cell itself, nor a randomized dissociation of the cross walls, but results (...) from a physical control with interaction between adjacent cells. It is independent of the cellular program responsible for the appearance of patterns like 2/5 phyllotaxis which is of a pentameric nature. (shrink)

The development of the typical cladomothallus of the red algae Antithaminion plumula (Ellis) Le Jolis [= Pterothamnion plumula (Ellis) Nägcli], (Rhodophyceae, Ceramiales) is simulated with the help of a formal language called L-systems. Two types of uniseriate filaments are distinguished: axial filaments of cladomes with indefinite growth and branching and pleuridia with definite growth and branching. The rythmical acropetal formation of secondary axes with basitonic arrangement contrasts with the intercalary basitonic formation of pleuridia, resulting in an acrotonic arrangement within an (...) axial segment. Five types of cells and two types of cell divisions intervene in the system. In addition, for the graphical representations, some morphological particularities of A. plumula are taken into account: the curvature of axial filaments, the extension of growth zones, variable cell generation times, and segment length variability along an axis. The incidence of these variables on the generated thallus form is emphasized, pointing to the singularities of A. plumula. (shrink)

Data from experiments on Erica × darleyensis and from related observations (Viémont and Beaujard, 1983) are taken for a critical analysis of the proposed model of morphogenetic phenomena. The criteria for judging the coherence of the constructions proposed in plant morphology are based on mathematical constructions deduced from Petri nets, especially elementary nets.
