A methodology to institutionalise user experience in a South African provincial government

The number of citizens, who access e-Government websites, is growing significantly and their expectations for additional services are increasing. The Internet has become an essential instrument to distribute information to citizens. Poorly designed websites, however, can divide governments and its citizens. Consensus amongst researchers is that user experience (UX) is an important factor in designing websites specifically e-Government websites. Problems, experienced with website usability, prevent people from accessing and eventually adopting technology, such as e-Government. Countries, such as the United States, United Kingdom and Canada, have shown increased support for UX in e-Government websites. At present, a number of guidelines and design principles exists for e-Government website UX design; however, the effectiveness of the implementation of these guidelines and principles depends on the profiles of the individuals on a website development team and on an organisation’s understanding of UX. Despite the highlighted importance of UX, guidelines and principles are rarely adopted in South African e-Government websites. Usability and UX guidelines cannot be implemented; if there is no executive support; an inadequately trained staff; no routine UX practice; insufficient budget; inefficient use of usability methodologies and user-centred design (UCD) processes. The challenge at present in the UX design field is the institutionalisation of UX, specifically at government level. The goal of this research was to propose and evaluate a methodology to institutionalise UX in South African Provincial Governments (PGs), named the “Institutionalise UX in Government (IUXG) methodology”. The research used the Western Cape Government (WCG) in South Africa as a case study to evaluate the proposed methodology to institutionalise UX in a South African PG. The IUXG methodology (1.0) was proposed from five UX methodologies, as well as from best practices found in literature. The IUXG methodology (1.1) was updated, based on results of a survey to South African PGs, a survey to WCG employees, as well as literature from the WCG. The IUXG methodology (2.0) was updated a final time, based on the case study results and on a confirmation survey with WCG employees after the implementation of the case study. The research study made use of three surveys during this research. The first survey, incorporating UX maturity models, confirmed that understanding and buy-in of UX are limited and that UX maturity levels are low at South African PG level. The second and third surveys were administered to WCG e-Government website officials before and after the implementation of the IUXG methodology. The surveys measured the UX maturity level of the WCG in the component, e-Government for Citizens (e-G4C), responsible for the WCG e-Government website. The final survey results demonstrated that, after the implementation of the IUXG methodology, the WCG improved its level of UX maturity on the identified UX maturity models. Implementation of the IUXG methodology institutionalised UX in the WCG. UX activities became standard practice in the e-Government website environment after the systems development lifecycle (SDLC) incorporated UCD. UX policy, strategy and guidelines were documented for the WCG e-Government website. The WCG constructed the first usability testing facility for a South African PG and improvements to the WCG e-Government website were implemented. The proposed IUXG methodology institutionalised UX in the WCG e-Government website environment. This research is a major contribution, to addressing the current lack of UX practices in South African PGs. South African PGs can use the proposed IUXG methodology to institutionalise UX and it will assist PG officials to develop increased UX maturity levels. The advantage of the IUXG methodology is that it provides PG officials with a step-by-step method how to institutionalise UX in a PG by following the six phases of the IUXG methodology: startup, setup, organisation, method, standards and long-term. The IUXG methodology will assist South African PGs to establish UX practice as a norm. The IUXG methodology will assist PGs with the resources, methods and tools to enable them to implement UX guidelines, which will result in an improved, more usable and more user-centric PG e-Government website

A Critique of Personas as representations of "the other" in Cross-Cultural Technology Design

A literature review on cross-cultural personas reveals both, a trend in projects lacking accomplishment and personas reinforcing previous biases. We first suggest why failures or incompleteness may have ensued, while then we entice a thoughtful alteration of the design process by creating and validating personas together with those that they embody. Personas created in people's own terms support the design of technologies by truly satisfying users' needs and drives. Examining the experiences of those working "out there", and our practises, we conclude persona is a vital designerly artefact to empowering people in representing themselves. A persona-based study on User-Created Persona in Namibia contrasts the current persona status-quo via an ongoing co-design effort with urban and rural non-designers. However we argue persona as a design device must ease its implicit colonial tendency to and impulses in depicting "the other". Instead we endorse serenity, mindfulness and local enabling in design at large and in the African context in particular

Academic group and forum on Facebook : social, serious studies or synergy?

An academic group and discussion forum were established on Facebook for a cohort of postgraduate students studying the concepts and principles of eLearning. The Forum had a constructivist, student-centric ethos, in which students initiated topics for discussion, while the course leader and administrator facilitated. Previous research has been conducted, involving content analysis of the topics and academic discourse, but the present study focuses on social aspects, investigating social- and study-related pursuits and determining whether synergy can exist between them. A literature review shows how social networking by students, initially social, began to overlap with academia, leading to the use of groups for academic purposes and forums for subject-related discussions. In the present study, data was triangulated and two methods of data analysis were used. Qualitative analysis was done on free-text data from students’ reflective essays to extract socially-related themes. Heuristic evaluation was conducted by expert evaluators, who investigated forum discourse in line with contemporary learning theory and who considered the social culture of participation. Findings of the qualitative analysis of students’ perceptions and results of the heuristic evaluation of forum participation confirmed each other, indicating a warm social climate and a conducive, well-facilitated environment that supported individual participation styles. It fostered inter-personal relationships between distance learners, as well as study-related relationships due to peer teaching and insights acquired from social negotiation. The environment supported student-initiative, but was moderated by facilitators. The mixed-methods research approach of evaluating students’ essays and conducting expert analysis of forum discussions showed the advent of a virtual community with a synergy between social aspects and academia. Most participants experienced a sound balance of social- and study-related benefits, but with a stronger focus on academic matters.Computin

Fungicides and the grapevine wood mycobiome: a case study on Tracheomycotic Ascomycete Phaemoniella chlamydospora reveals potential for two novel control strategies

Original ResearchPhaeomoniella chlamydospora is a tracheomycotic fungus that colonizes the xylem of grapevines (Vitis vinifera L.), causing wood discoloration, brown wood streaking, gummosis, and wood necrosis, which negatively affect the overall health, productivity, and life span of vines. Current control strategies to prevent or cope with P. chlamydospora infections are frequently ineffective. Moreover, it is unclear how fungicides commonly applied in vineyards against downy and powdery mildew agents affect the wood mycobiome, including wood pathogens such as P. chlamydospora. In this study, we used next-generation sequencing to assess the effects of foliar spray of grapevines with inorganic (copper oxychloride and sulfur), synthetic (penconazole and fosetyl-aluminum), and natural (Blad) fungicides currently used against the downy and powdery mildews. The subjects of our investigation were (i) the resident wood mycobiome, (ii) the early colonization by a consortium of fungal wood endophytes (ACEA1), (iii) the wood colonization success of P. chlamydospora, and (iv) the in planta interaction between P. chlamydospora and ACEA1, under greenhouse conditions, in rooted grapevine cuttings of cv. Cabernet Sauvignon. The data obtained suggest that the resident mycobiome is affected by different fungicide treatments. In addition, the early colonization success of the endophytes composing ACEA1 varied in response to fungicides, with relative abundances of some taxa being overrepresented or underrepresented when compared with the control. The wood colonization by P. chlamydospora comported significant changes in the mycobiome composition, and in addition, it was greatly affected by the foliar spray with Blad, which decreased the relative abundance of this pathogen 12-fold (4.9%) when compared with the control (60.7%) and other treatments. The presence of the pathogen also decreased considerably when co-inoculated into the plant with ACEA1, reaching relative abundances between 13.9% and 2.0%, depending on the fungicide treatment applied. This study shows that fungicides sprayed to prevent infections of powdery and downy mildews have an control strategies to fight P. chlamydospora, namely, the foliar spray with Blad and the use of ACEA1. Further studies to confirm these results are requiredinfo:eu-repo/semantics/publishedVersio

Annual research review: Digital health interventions for children and young people with mental health problems: a systematic and meta-review

Digital health interventions (DHIs), including computer-assisted therapy, smartphone apps and wearable technologies, are heralded as having enormous potential to improve uptake and accessibility, efficiency, clinical effectiveness and personalisation of mental health interventions. It is generally assumed that DHIs will be preferred by children and young people (CYP) given their ubiquitous digital activity. However, it remains uncertain whether: DHIs for CYP are clinically and cost-effective, CYP prefer DHIs to traditional services, DHIs widen access and how they should be evaluated and adopted by mental health services. This review evaluates the evidence-base for DHIs and considers the key research questions and approaches to evaluation and implementation. We conducted a meta-review of scoping, narrative, systematic or meta-analytical reviews investigating the effectiveness of DHIs for mental health problems in CYP. We also updated a systematic review of randomised controlled trials (RCTs) of DHIs for CYP published in the last 3 years. Twenty-one reviews were included in the meta-review. The findings provide some support for the clinical benefit of DHIs, particularly computerised cognitive behavioural therapy (cCBT), for depression and anxiety in adolescents and young adults. The systematic review identified 30 new RCTs evaluating DHIs for attention deficit/hyperactivity disorder (ADHD), autism, anxiety, depression, psychosis, eating disorders and PTSD. The benefits of DHIs in managing ADHD, autism, psychosis and eating disorders are uncertain, and evidence is lacking regarding the cost-effectiveness of DHIs. Key methodological limitations make it difficult to draw definitive conclusions from existing clinical trials of DHIs. Issues include variable uptake and engagement with DHIs, lack of an agreed typology/taxonomy for DHIs, small sample sizes, lack of blinded outcome assessment, combining different comparators, short-term follow-up and poor specification of the level of human support. Research and practice recommendations are presented that address the key research questions and methodological issues for the evaluation and clinical implementation of DHIs for CYP

A Methodology to Institutionalise User Experience in Provincial Government

Problems experienced with website usability can prevent users from accessing and adopting technology, such as e-Government. At present, a number of guidelines exist for e-Government website user experience (UX) design; however, the effectiveness of the implementation of these guidelines depends on the expertise of the website development team and on an organisation’s understanding of UX. Despite the highlighted importance of UX, guidelines are rarely applied in South African e-Government website designs. UX guidelines cannot be implemented if there is a lack of executive support, trained staff, budget and user-centred design processes. The goal of this research is to propose and evaluate a methodology (called the “Institutionalise UX in Government (IUXG) methodology”) to institutionalise UX in South African Provincial Governments (SAPGs). The Western Cape Government in South Africa was used as a case study to evaluate the proposed IUXG methodology. The results show that the IUXG methodology can assist SAPGs to establish UX as standard practice and improve the UX maturity levels

Transcriptional control of glucoamylase synthesis in vegetatively growing and sporulating Saccharomyces species

Three unlinked, homologous genes, STA1, STA2, and STA3, encode the extracellular glycosylated glucoamylase isozymes I, II, and III, respectively, in Saccharomyces species. S. cerevisiae, which is sta0 (absence of functional STA genes in haploids), does carry a glucoamylase gene, delta sta, expressed only during sporulation (W. J. Colonna and P. T. Magee, J. Bacteriol. 134:844-853, 1978; I. Yamashita and S. Fukui, Mol. Cell. Biol. 5:3069-3073, 1985). In this study we examined some of the physiological and genetic factors that affect glucoamylase expression. It was found that STA2 strains grown in synthetic medium produce glucoamylase only in the presence of either Maltrin M365 (a mixture of maltooligosaccharides) or starch. Maximal levels of glucoamylase activity were found in cells grown in rich medium supplemented with glycerol plus ethanol, starch, or Maltrin. When various sugars served as carbon sources they all supported glucoamylase synthesis, although at reduced levels. In any given growth medium glucoamylase isozyme II synthesis was modulated by functionality of the mitochondria. Synthesis of glucoamylase is continuous throughout the growth phases, with maximal secretion taking place in the early stationary phase. In the various regimens, the differences in enzyme accumulation are accounted for by differences in the levels of glucoamylase mRNA. Both glucoamylase mRNA and enzyme activity were drastically and coordinately inhibited in MATa/MAT alpha diploids and by the presence of the regulatory gene STA10. Both effects were partially overcome when the STA2 gene was present on a multicopy plasmid. The STA2 mRNA and glucoamylase were coinduced in sporulating STA2/STA2 diploids. A smaller, coinduced RNA species was also detected by Northern blotting with a STA2 probe. The same mRNA species was detected in sporulating sta0 diploids and is likely to encode the sporulation-specific glucoamylase.8 page(s

Msn1p/Mss10p, Mss11p and Muc1p/Flo11p are part of a signal transduction pathway downstream of Mep2p regulating invasive growth and pseudohyphal differentiation in Saccharomyces cerevisiae

In Saccharomyces cerevisiae, a network of signal transduction pathways governs the switch from yeast-type growth to pseudohyphal and invasive growth that occurs in response to nutrient limitation. Important elements of this network have been identified, including nutrient signal receptors, GTP-binding proteins, components of the pheromone-dependent MAP kinase cascade and several transcription factors. However, the structural and functional mapping of these pathways is far from complete. Here, we present data regarding three genes, MSN1/MSS10, MSS11 and MUC1/FLO11, which form an essential part of the signal transduction network establishing invasive growth. Both MSN1 and MSS11 are involved in the co-regulation of starch degradation and invasive growth. Msn1p and Mss11p act downstream of Mep2p and Ras2p and regulate the transcription of both STA2 and MUC1. We show that MUC1 mediates the effect of Msn1p and Mss11p on invasive growth. In addition, our results suggest that the activity of Msn1p is independent of the invasive growth MAP kinase cascade, but that Mss11p is required for the activation of pseudohyphal and invasive growth by Ste12p. We also show that starch metabolism in S. cerevisiae is subject to regulation by components of the MAP kinase cascade.14 page(s

Divergent Regulation of the Evolutionarily Closely Related Promoters of the Saccharomyces cerevisiae STA2 and MUC1 Genes

The 5′ upstream regions of the Saccharomyces cerevisiae glucoamylase-encoding genes STA1 to -3 and of the MUC1 (or FLO11) gene, which is critical for pseudohyphal development, invasive growth, and flocculation, are almost identical, and the genes are coregulated to a large extent. Besides representing the largest yeast promoters identified to date, these regions are of particular interest from both a functional and an evolutionary point of view. Transcription of the genes indeed seems to be dependent on numerous transcription factors which integrate the information of a complex network of signaling pathways, while the very limited sequence differences between them should allow the study of promoter evolution on a molecular level. To investigate the transcriptional regulation, we compared the transcription levels conferred by the STA2 and MUC1 promoters under various growth conditions. Our data show that transcription of both genes responded similarly to most environmental signals but also indicated significant divergence in some aspects. We identified distinct areas within the promoters that show specific responses to the activating effect of Flo8p, Msn1p (or Mss10p, Fup1p, or Phd2p), and Mss11p as well as to carbon catabolite repression. We also identified the STA10 repressive effect as the absence of Flo8p, a transcriptional activator of flocculation genes in S. cerevisiae
