From appfest to entrepreneurs: using a hackathon event to seed a university student-led enterprise
Hackathons were once industry-specific programming sprints to get overdue features and applications completed; today they are a worldwide phenomenon, with businesses, educators, and entrepreneurs taking an interest in the benefits they can provide. Hackathons can be a breeding ground for brainstorming, innovation, networking, and product development, and as such they can have multiple outcomes including the sparking of new businesses and entrepreneurial activity. This paper investigates the effectiveness of utilising a hackathon as the genesis for the creation of sustainable student entrepreneurial activity. In particular, it seeks to evaluate the effectiveness of using hackathon-type events to initiate a successful University student enterprise project. The paper outlines the findings from this project, and concludes with a series of recommendations from the authors, on how one should market and structure a hackathon, and whether this vehicle should be chosen as a means to initiate a student enterprise project.
The key factors that led to the success of this project were: the degree of formal structure that was introduced into the timings of the principle activities, not normally a feature of this kind of event, including scheduled “diversions” to break up the weekend; keeping the goals achievable; the duration of the event, in this case 48 hours spread over three days; the involvement of representatives from local businesses in the judging process; and crucially the adoption of an over-riding ethos for the event that focussed not on providing completed problem solutions but on potential innovative solutions that may not have been fully-functional.
Areas for improvement included: inviting more students from earlier study years of degree programmes, not always the target audience for University hackathon activity; inviting students from a wide range of disciplines to ensure a broad set of participant skills and to encourage the formation of multi-disciplinary groupings by enforcing a balance of skills across teams, which as a corollary means not always allowing friendship groups to remain together; employing a team sufficiently large enough to support the duration of a long event; and careful consideration of the extent of competitiveness adopted in the event ethos.
The project was part of the institution’s “Student as Producer” initiative where students and staff work side-by-side on research projects. Undergraduate students were fully involved in all aspects of the project, including an independent team who contributed to the authoring of this paper
From hackathon to student enterprise: an evaluation of creating successful and sustainable student entrepreneurial activity initiated by a university hackathon
Hackathons are a worldwide phenomenon, with both industry and educators considering the opportunities and benefits that they generate. They can provide a forum for innovation, networking, and product design and development, thereby offering multiple outcomes. This paper develops the authors’ previous work on the effectiveness of utilising a hackathon as the spark for initiating student entrepreneurial activity by considering the success of the student enterprise that was created as a result and the extent to which that success was attributable to the hackathon event. Using a case study approach, the paper seeks to evaluate the effectiveness of using hackathon-type events to initiate a successful University student enterprise project and to identify the key elements in the future organisation of such a hackathon event that might lead to a sustainable and effective student enterprise. The paper outlines the findings from this project, which focus on the team building and bonding that take place in such an event, and concludes with a series of recommendations from the authors on how one should market and structure a hackathon to best ensure the success of a subsequently formed student enterprise, based on the evaluation of the project one year after it was founded.
The evaluation of the project was undertaken as part of the institution’s “Student as Producer” initiative where students and staff work side-by-side on research projects. An independent team of undergraduate students was fully involved in all aspects of the project evaluation, including the authoring of this paper
87th Annual Georgia Public Health Association Meeting & Conference Report
The 87th Annual Meeting of the Georgia Public Health Association (GPHA) was held in Atlanta, Georgia, on March 22-23, 2016, with pre-conference (March 21st) and post-conference (March 23rd) Executive Board meetings. As Georgia’s leading forum for public health researchers, practitioners, and students, the annual meeting of the GPHA brings together participants from across the state to explore recent developments in the field and to exchange techniques, tools, and experiences. In recent years the venue for the GPHA annual conference has been Atlanta, with the 2017 GPHA Annual Meeting and Conference also scheduled to be held in Atlanta. Several new initiatives were highlighted as part of this year’s conference. These included three pre-conference workshops, expansion of academic sponsorships, an enhanced exhibit hall integrated with the poster sessions, silent auction, breaks and President’s Reception, an information booth, and an inaugural administration section track. The 2016 Annual Meeting & Conference added the Certified in Public Health (CPH) Continuing Education (CE) designation.
The theme for the conference was Understanding Public Health: Research, Evidence and Practice, which reflects the science of public health
Advances in establishment and analysis of three-dimensional tumor spheroid-based functional assays for target validation and drug evaluation
There is overwhelming evidence that in vitro three-dimensional tumor cell cultures more accurately
reflect the complex in vivo microenvironment than simple two-dimensional cell monolayers, not least with respect
to gene expression profiles, signaling pathway activity and drug sensitivity. However, most currently available threedimensional
techniques are time consuming and/or lack reproducibility; thus standardized and rapid protocols are
urgently needed. To address this requirement, we have developed a versatile toolkit of reproducible three-dimensional
tumor spheroid models for dynamic, automated, quantitative imaging and analysis that are compatible with
routine high-throughput preclinical studies. Not only do these microplate methods measure three-dimensional
tumor growth, but they have also been significantly enhanced to facilitate a range of functional assays
exemplifying additional key hallmarks of cancer, namely cell motility and matrix invasion. Moreover, mutual tissue
invasion and angiogenesis is accommodated by coculturing tumor spheroids with murine embryoid bodies within
which angiogenic differentiation occurs. Highly malignant human tumor cells were selected to exemplify
therapeutic effects of three specific molecularly-targeted agents: PI-103 (phosphatidylinositol-3-kinase (PI3K)-
mammalian target of rapamycin (mTOR) inhibitor), 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) (heat
shock protein 90 (HSP90) inhibitor) and CCT130234 (in-house phospholipase C (PLC)g inhibitor). Fully automated
analysis using a Celigo cytometer was validated for tumor spheroid growth and invasion against standard image
analysis techniques, with excellent reproducibility and significantly increased throughput. In addition, we
discovered key differential sensitivities to targeted agents between two-dimensional and three-dimensional
cultures, and also demonstrated enhanced potency of some agents against cell migration/invasion compared with
proliferation, suggesting their preferential utility in metastatic disease.: We have established and validated a suite of highly reproducible tumor microplate threedimensional
functional assays to enhance the biological relevance of early preclinical cancer studies. We believe
these assays will increase the translational predictive value of in vitro drug evaluation studies and reduce the need
for in vivo studies by more effective triaging of compounds.This work was

What next for unions in Central and Eastern Europe? Invisibility, departure and the transformation of industrial relations
This article examines union revitalization in Central and Eastern Europe, focusing on two countries: Hungary and Latvia. Trade unions have not only had to cope with a declining membership base, but have also had to respond to austerity programmes and government cuts in public sector employment. We argue that the inability of unions to provide a strong voice for alternative policies to the current neoliberal orthodoxy has been driven by a declining membership base, but also by weakened social dialogue mechanisms, limited industrial representation and an ageing membership profile, exacerbated by net outward migration in recent years. However, we find that unions in Latvia and Hungary have responded differently to these issues
Variant of TYR and Autoimmunity Susceptibility Loci in Generalized Vitiligo.
BACKGROUND
Generalized vitiligo is an autoimmune disease characterized by melanocyte loss, which results in patchy depigmentation of skin and hair, and is associated with an elevated risk of other autoimmune diseases.
METHODS
To identify generalized vitiligo susceptibility loci, we conducted a genomewide association study. We genotyped 579,146 single-nucleotide polymorphisms (SNPs) in 1514 patients with generalized vitiligo who were of European-derived white (CEU) ancestry and compared the genotypes with publicly available control genotypes from 2813 CEU persons. We then tested 50 SNPs in two replication sets, one comprising 677 independent CEU patients and 1106 CEU controls and the other comprising 183 CEU simplex trios with generalized vitiligo and 332 CEU multiplex families.
RESULTS
We detected significant associations between generalized vitiligo and SNPs at several loci previously associated with other autoimmune diseases. These included genes encoding major-histocompatibility-complex class I molecules (P=9.05×10−23) and class II molecules (P=4.50×10−34), PTPN22 (P=1.31×10−7), LPP (P=1.01×10−11), IL2RA (P=2.78×10−9), UBASH3A (P=1.26×10−9), and C1QTNF6 (P=2.21×10−16). We also detected associations between generalized vitiligo and SNPs in two additional immune-related loci, RERE (P=7.07×10−15) and GZMB (P=3.44×10−8), and in a locus containing TYR (P=1.60×10−18), encoding tyrosinase.
CONCLUSIONS
We observed associations between generalized vitiligo and markers implicating multiple genes, some associated with other autoimmune diseases and one (TYR) that may mediate target-cell specificity and indicate a mutually exclusive relationship between susceptibility to vitiligo and susceptibility to melanoma
Common variants in FOXP1 are associated with generalized vitiligo
In a recent genome-wide association study of generalized vitiligo, we identified ten confirmed susceptibility loci. By testing additional loci that showed suggestive association in the genome-wide study, using two replication cohorts of European descent, we observed replicated association of generalized vitiligo with variants at 3p13 encompassing FOXP1 (rs17008723, combined P = 1.04 × 10−8) and with variants at 6q27 encompassing CCR6 (rs6902119, combined P = 3.94 × 10−7)
Does a SLAP lesion affect shoulder muscle recruitment as measured by EMG activity during a rugby tackle?
Background: The study objective was to assess the influence of a SLAP lesion on onset of EMG activity in shoulder muscles during a front on rugby football tackle within professional rugby players.
Methods: Mixed cross-sectional study evaluating between and within group differences in EMG onset times. Testing was carried out within the physiotherapy department of a university sports medicine clinic. The test group consisted of 7 players with clinically diagnosed SLAP lesions, later verified on arthroscopy. The reference group consisted of 15 uninjured and full time professional rugby players from within the same playing squad. Controlled tackles were performed against a tackle dummy. Onset of EMG activity was assessed from surface EMG of Pectorialis Major, Biceps Brachii, Latissimus Dorsi, Serratus Anterior and Infraspinatus muscles relative to time of impact. Analysis of differences in activation timing between muscles and limbs (injured versus non-injured side and non injured side versus matched reference group).
Results: Serratus Anterior was activated prior to all other muscles in all (P = 0.001-0.03) subjects. In the SLAP
injured shoulder Biceps was activated later than in the non-injured side. Onset times of all muscles of the noninjured shoulder in the injured player were consistently earlier compared with the reference group. Whereas, within
the injured shoulder, all muscle activation timings were later than in the reference group.
Conclusions: This study shows that in shoulders with a SLAP lesion there is a trend towards delay in activation time of Biceps and other muscles with the exception of an associated earlier onset of activation of Serratus anterior, possibly due to a coping strategy to protect glenohumeral stability and thoraco-scapular stability. This
trend was not statistically significant in all cases
Globalization, democratization, and the Arab uprising : the international factor in MENA's failed democratization
What explains the almost negative impact of international factors on post-Uprising democratization prospects? This article compares the utility of rival “diffusionist” and neo-Gramscian political economy frames to explain this. Three international factors deter democratization. The failure of Western democracy promotion is rooted in the contradiction between the dominance of global finance capital and the norm of democratic equality; in the periphery, neo-liberalism is most compatible with hybrid regimes and, at best, “low intensity democracy.” In MENA, neo-liberalism generated a crony capitalism incompatible with democratization; while this also sparked the uprisings, these have failed to address class inequalities. Moreover at the normative level, MENA hosts the most credible counter-hegemonic ideologies; the brief peaking of democratic ideology in the region during the early uprisings soon declined amidst regional discourse wars. Non-democrats—coercive regime remnants and radical charismatic movements--were empowered by the competitive interference of rival powers in Uprising states. The collapse of many Uprising states amidst a struggle for power over the region left an environment uncongenial to democratization.PostprintPeer reviewe
