Creating research-based design principles for interdisciplinary learning
Abstract
Over the last decade, the focus of K-12 and higher education has shifted significantly from disciplinary curricula to diverse interdisciplinary learning options. This has raised new questions about how people learn across disciplines. One of the biggest concerns is that interdisciplinary courses lack robust theoretical and pedagogical grounding, and research that informs design is particularly needed. However, such research requires bringing a range of different conceptual, pedagogical, and methodological ideas together. The main aim of this workshop is to articulate foundational ideas and methods for creating research-based design principles for interdisciplinary learning. It brings two main audiences: 1) those who are interested in the substantial questions of interdisciplinary learning, and 2) those who are interested in the methodological questions of creating research-based actionable knowledge for design. Workshop participants will work together on producing recommendations on creating research-based design principles for interdisciplinary learning
Association of Distal Deletion of the Short arm of Chromosome 9 with 46,XY Disorder of Sex Development and Gonadoblastoma
Deletion of the short arm of chromosome 9 is associated with two distinct clinical prototypes. Small telomeric distal 9p deletions have been reported in patients 46,XY with gonadal dysgenesis, this region contains genes required in two copies for normal testis development. Recent studies have narrowed the interval 9p24.3-pter containing the putative autosomal testis-determining gene(s) known as domain DMRT. On the other hand, and depending on the extent of deletion of the short arm, the clinical characteristics of monosomy 9p syndrome may emerge. We present an infant female with complete 46,XY gonadal dysgenesis, who was examined for motor developmental retardation. In the karyotype a chromosomal deletion 9p24.1 was identified by cytogenetic and fluorescence in situ hybridization studies. No SRY deletion or mutation was detected. Ultrasonographic studies showed a normal uterus. Basal luteinizing hormone and follicle stimulating hormone values were high. The patient underwent gonadectomy at 3.2 years of age, and histologic analysis disclosed dysgenetic gonads with gonadoblastoma.Fil: del Rey, Graciela Monica.

Next-generation cellulosic ethanol technologies and their contribution to a sustainable Africa
The world is currently heavily dependent on oil, especially in the transport sector. However, rising oil prices, concern about environmental impact and supply instability are among the factors that have led to greater interest in renewable fuel and green chemistry alternatives. Lignocellulose is the only foreseeable renewable feedstock for sustainable production of transport fuels. The main technological impediment to more widespread utilization of lignocellulose for production of fuels and chemicals in the past has been the lack of low-cost technologies to overcome the recalcitrance of its structure. Both biological and thermochemical second-generation conversion technologies are currently coming online for the commercial production of cellulosic ethanol concomitantly with heat and electricity production. The latest advances in biological conversion of lignocellulosics to ethanol with a focus on consolidated bioprocessing are highlighted. Furthermore, integration of cellulosic ethanol production into existing bio-based industries also using thermochemical processes to optimize energy balances is discussed. Biofuels have played a pivotal yet suboptimal role in supplementing Africa's energy requirements in the past. Capitalizing on sub-Saharan Africa's total biomass potential and using second-generation technologies merit a fresh look at the potential role of bioethanol production towards developing a sustainable Africa while addressing food security, human needs and local wealth creation
