Bridging the digital divide for hard-to-reach groups

Boeltzig and Pilling identified specific groups of people who typically are not connected to the Internet and examined the circumstances of each - rural, poor, disabled, seniors, and ethnic minorities. They focused on how these groups of people, such as homebound individuals, could benefit most from using online government services. They also identified technical as well as social barriers that limit access. Their recommendations are aimed at both increasing access for these targeted groups and increasing use by individuals in the targeted groups. They also provide valuable recommendations aimed at service or application providers who have a major role in increasing both access and accessibility. The case studies resulted in insights and lessons that are broadly applicable. Based on the case studies, the authors offer recommendations that are practical and serve as useful guides to practitioners and policy makers at all levels of government

Does science need computer science?

IBM Hursley Talks Series 3An afternoon of talks, to be held on Wednesday March 10 from 2:30pm in Bldg 35 Lecture Room A, arranged by the School of Chemistry in conjunction with IBM Hursley and the Combechem e-Science Project.The talks are aimed at science students (undergraduate and post-graduate) from across the faculty. This is the third series of talks we have organized, but the first time we have put them together in an afternoon. The talks are general in nature and knowledge of computer science is certainly not necessary. After the talks there will be an opportunity for a discussion with the lecturers from IBM.Does Science Need Computer Science?Chair and Moderator - Jeremy Frey, School of Chemistry.- 14:00 "Computer games for fun and profit" (*) - Andrew Reynolds - 14:45 "Anyone for tennis?

Discipline, profession and industry: how our choices shape our future

At the time of writing the practice of coaching is definitely an industry, could be underpinned by a discipline but is yet to be a profession. The current situation is fluid and dynamic. It is evolving as choices are made by practitioners, researchers, Universities and nascent professional bodies. Whether coaching ends up as a chartered profession in its own right, a sub-discipline of psychology, education, or a professional practice of Human Resource Management will have a significant impact on the conduct of the work itself and how it is understood. The status of coaches will to a large extent be determined by their autonomy, influence and perceived value to clients. This chapter examines the implication of an increasingly professionalised practice of coaching and what this means for coaches either as sole practitioners or employees and the expectations that clients can have of the increasingly professional coach. Our analysis draws first upon the sociology of professional work particularly that of Evetts (2013) on the analysis of professional work and the concepts of profession, professionalization and professionalism. We compare coaching with the experience of other areas of practice such as nursing, consulting and social care as they too seek to differentiate their work. Having considered the professional perspective we then turn to the concept of coaching as an academic discipline in part drawing on the constructs developed by Foucault (1975) and others. This analysis highlights how the trends in an increasingly professional coaching practice will have impact upon the work and specifically the issue of alleviation of risk. This brings into focus the ethical aspects of the intervention requiring both scrutiny of standards and regulation with an inherent requirement for qualification. There is also the highly political question of who determines what epistemology is appropriate for the body of knowledge. This question has been robustly debated by amongst others Fillery-Travis & Passmore (2011) and Corrie (2014). The divergent opinion in the literature exists, in part, due to the varying backgrounds of the coaches who seek to apply to coaching research the same criteria for rigor they used in their original discipline. The ‘ownership’ of the body of knowledge is thus critical in determining what research strategy is followed and what evidence is produced and by whom. The answer to these issues determines what questions are or are not asked and therefore how coaching evolves. The list above contains a number of the essential elements that identify a practice to be a profession or a discipline. They have been previously considered by Hawkins (2008), Cavanagh and Grant (2004), Lane (2014) as well as within a recent history by Stec (2012) but this chapter extends the analysis to first consider the place of professions within the organizational context and then within the wider context of the professions in general and the emergent ones specifically. This will allow the coaching practitioner and our associations a framework to consider and plan for the potential challenges of the future and hence design both their individual and collective development

Antibiotic activity of two Anabaena species against four fish pathogenic Aeromonas species

Three organic extracts (chloroform, ethyl acetate and n-butanol) of ten cyanobacterial species (Anabaena solitaria, Anabaena variabilis, Anabaena cylindrical, Anabaena spiroides, Anabaenacircinalis, Oscillatoria ornate, Oscillatoria salins, Oscillatoria tenuis, Oscillatoria rubescens and Oscillatoria prolifica) were investigated for their antibacterial activities against 4 fish pathogenicbacterial species belonging to genus Aeromonas, namely, Aer. salmonicida, Aer. hydrophila, Aer. formicans and Aer. liquefaciens using oxytetracycline as reference antibiotic. Of all cyanobacterialsamples, only ethyl acetate extracts of A. variabilis and A. circinalis were proved to be the most effective against all tested Aeromonas species. Bioautographic investigation for 13 organic solventsystems indicate that the spot with Rf = 0.79 for A. variabilis and that of Rf = 0.84 for A. circinalis were the most effective. The median lethal doses (LD50) for the purified antibacterial compounds against micewere 246.67 and 231.67 mg/kg for that extracted from A. variabilis and A. circinalis, respectivel

Relationship Between the Cortisol-Estradiol Phase Difference and Affect in Women

Affective disorders impact women’s health, with a lifetime prevalence of over twelve per cent. They have been correlated with reproductive cycle factors, under the regulation of hormonal circadian rhythms. In affective disorders, circadian rhythms may become desynchronized. The circadian rhythms of cortisol and estradiol may play a role in affective disorders. The purpose of this study was to explore the temporal relationship between the rhythms of cortisol and estradiol and its relationship to affect. It was hypothesized that a cortisol-estradiol phase difference (PD) exists that correlates with optimal affect. A small scale, comparative, correlational design was used to test the hypothesis. Twenty-three women were recruited from an urban university. Salivary samples were collected over a twenty-four-hour period and fitted to a cosinor model. Subjective measures of affect were collected. Relationships between the cortisol-estradiol PD and affect were evaluated using a second-degree polynomial equation. Results demonstrated a significant correlation in affect measures (p \u3c 0.05). An optimal PD was identified for affect to be 3.6 hours. The phase relationship between cortisol and estradiol may play a role in the development of alterations in affective disorders
