Embedding Employability Survey: Insights from Student, Graduate, Staff and Employer Voice Profiles

The Embedding Employability Survey was conducted by the Careers and Employability Centre, Dundalk Institute of Technology May to June 2021. Engaging relevant stakeholders, namely; students, graduates, DkIT staff and employers, the survey aimed to uncover attitudes, experiences, insights, and future-oriented thinking about employability for graduates of the institute. The results informed the development of a national award-winning graduate attribute programme, and proposes the PCs Graduate Attributes and Mindsets Framework (AHECS 2022, Guidance Counsellors for HEIs in Ireland, Winner). The survey was funded by the National Forum for the Enhancement of Teaching and Learning (Ireland), as part of their Strategic Alignment for Teaching and Learning Enhancement Fund 2019. Participants answered a wide range of questions addressing four key themes: (i) our graduate attributes, (ii) employability factors affecting our graduates’ perceived employability, (iii) the utility and effectiveness of Careers & Employability Services, and (iv) forward-looking employability plans for DkIT. All completed online by email call-to-action due to the ongoing Covid-19 context. Building on focus group consultations, the survey set about: testing consensus regarding a headline for our graduate attribute framework, highlighting key employability best practices, reaching consensus on Career and Employability Services, and pointing to future directions for employability at DkIT. This report presents the main findings, draws out key points of guidance and demonstrates how to conduct a multi-stakeholder survey to inform a higher education institute (HEI) Employability Plan

Challenges of biobanking in South Africa to facilitate indigenous research in an environment burdened with human immunodeficiency virus, tuberculosis, and emerging non-communicable diseases

The high burden of infectious diseases and the growing problem of noncommunicable and metabolic disease syndromes in South Africa (SA) forces a more focused research approach to facilitate cutting-edge scientific growth and public health development. Increased SA research on these diseases and syndromes and the collection of associated biospecimens has ensured a plethora of biobanks created by individuals, albeit without the foresight of prospective and collective use by other local and international researchers. As the need for access to high-quality specimens in statistically relevant numbers has increased, so has the necessity for the development of national human biobanks in SA and across the Continent. The prospects of achieving sustainable centralized biobanks are still an emerging and evolving concept, primarily and recently driven by the launch of the H3Africa consortium, which includes the development of harmonized and standardized biobanking operating procedures. This process is hindered by a myriad of complex societal considerations and ethico-legal challenges. Efforts to consolidate and standardize biological sample collections are further compromised by the lack of full appreciation by national stakeholders of the biological value inherent in these collections, and the availability of high quality human samples with well-annotated data for future scientific research and development. Inadequate or nonexistent legislative structures that specifically regulate the storage, use, dispersal, and disposal of human biological samples are common phenomena and pose further challenges. Furthermore, concerns relating to consent for unspecific future uses, as well as access to information and data protection, are all new paradigms that require further consideration and public engagement. This article reviews important fundamental issues such as governance, ethics, infrastructure, and bioinformatics that are important foundational prerequisites for the establishment and evolution of successful human biobanking in South Africa.Web of Scienc

The bacterial gut microbiome of probiotic-treated very-preterm infants: changes from admission to discharge

Background: Preterm birth is associated with the development of acute and chronic disease, potentially, through the disruption of normal gut microbiome development. Probiotics may correct for microbial imbalances and mitigate disease risk. Here, we used amplicon sequencing to characterise the gut microbiome of probiotic-treated premature infants. We aimed to identify and understand variation in bacterial gut flora from admission to discharge and in association with clinical variables. Methods: Infants born <32 weeks gestation and <1500 g, and who received probiotic treatment, were recruited in North Queensland Australia. Meconium and faecal samples were collected at admission and discharge. All samples underwent 16S rRNA short amplicon sequencing, and subsequently, a combination of univariate and multivariate analyses. Results: 71 admission and 63 discharge samples were collected. Univariate analyses showed significant changes in the gut flora from admission to discharge. Mixed-effects modelling showed significantly lower alpha diversity in infants diagnosed with either sepsis or retinopathy of prematurity (ROP) and those fed formula. In addition, chorioamnionitis, preeclampsia, sepsis, necrotising enterocolitis and ROP were also all associated with the differential abundance of several taxa. Conclusions: The lower microbial diversity seen in infants with diagnosed disorders or formula-fed, as well as differing abundances of several taxa across multiple variables, highlights the role of the microbiome in the development of health and disease. This study supports the need for promoting healthy microbiome development in preterm neonates

Releasing incompatible males drives strong suppression across populations of wild and Wolbachia-carrying Aedes aegypti in Australia

Releasing sterile or incompatible male insects is a proven method of population management in agricultural systems with the potential to revolutionize mosquito control. Through a collaborative venture with the “Debug” Verily Life Sciences team, we assessed the incompatible insect technique (IIT) with the mosquito vector Aedes aegypti in northern Australia in a replicated treatment control field trial. Backcrossing a US strain of Ae. aegypti carrying Wolbachia wAlbB from Aedes albopictus with a local strain, we generated a wAlbB2-F4 strain incompatible with both the wild-type (no Wolbachia) and wMel-Wolbachia Ae. aegypti now extant in North Queensland. The wAlbB2-F4 strain was manually mass reared with males separated from females using Verily sex-sorting technologies to obtain no detectable female contamination in the field. With community consent, we delivered a total of three million IIT males into three isolated landscapes of over 200 houses each, releasing ∼50 males per house three times a week over 20 wk. Detecting initial overflooding ratios of between 5:1 and 10:1, strong population declines well beyond 80% were detected across all treatment landscapes when compared to controls. Monitoring through the following season to observe the ongoing effect saw one treatment landscape devoid of adult Ae. aegypti early in the season. A second landscape showed reduced adults, and the third recovered fully. These encouraging results in suppressing both wild-type and wMel-Ae. aegypti confirms the utility of bidirectional incompatibility in the field setting, show the IIT to be robust, and indicate that the removal of this arbovirus vector from human-occupied landscapes may be achievable

A Multilaboratory Comparison of Calibration Accuracy and the Performance of External References in Analytical Ultracentrifugation

Analytical ultracentrifugation (AUC) is a first principles based method to determine absolute sedimentation coefficients and buoyant molar masses of macromolecules and their complexes, reporting on their size and shape in free solution. The purpose of this multi-laboratory study was to establish the precision and accuracy of basic data dimensions in AUC and validate previously proposed calibration techniques. Three kits of AUC cell assemblies containing radial and temperature calibration tools and a bovine serum albumin (BSA) reference sample were shared among 67 laboratories, generating 129 comprehensive data sets. These allowed for an assessment of many parameters of instrument performance, including accuracy of the reported scan time after the start of centrifugation, the accuracy of the temperature calibration, and the accuracy of the radial magnification. The range of sedimentation coefficients obtained for BSA monomer in different instruments and using different optical systems was from 3.655 S to 4.949 S, with a mean and standard deviation of (4.304 ± 0.188) S (4.4%). After the combined application of correction factors derived from the external calibration references for elapsed time, scan velocity, temperature, and radial magnification, the range of s-values was reduced 7-fold with a mean of 4.325 S and a 6-fold reduced standard deviation of ± 0.030 S (0.7%). In addition, the large data set provided an opportunity to determine the instrument-to-instrument variation of the absolute radial positions reported in the scan files, the precision of photometric or refractometric signal magnitudes, and the precision of the calculated apparent molar mass of BSA monomer and the fraction of BSA dimers. These results highlight the necessity and effectiveness of independent calibration of basic AUC data dimensions for reliable quantitative studies
