Preparatory studies of zero-g cloud drop coalescence experiment

Experiments to be performed in a weightless environment in order to study collision and coalescence processes of cloud droplets are described. Rain formation in warm clouds, formation of larger cloud drops, ice and water collision processes, and precipitation in supercooled clouds are among the topics covered

Evaluation of data obtained from atmospheric laser Doppler velocimeter

The Doppler lidar velocimeter produces a variety of kinds of data. Besides the line of sight velocity components, there are the reflected amplitudes and the Doppler widths. Computer graphics software for displaying these data was produced. Different methods of presentation are needed for the various items. A picture was produced as pictures are often the best way to gain understanding. The individual lidar scans form a crosshatch pattern. Thus one-dimensional measurements fit together to form a two-dimensional whole. A pair of velocity measurements at a point combine to form a wind measurement with direction and magnitude. This gives a forest of wind vectors. The goal is to find a recognizable pattern to these trees. Often it is necessary to show only part of the information. That is, show only the wind direction not its magnitude or reduce the wind to streamlines of air flow. In other cases data are reduced to contour plots. Just enough contour lines are included to show the picture described

Animal Evolution: Once upon a Time

SummaryThe evolutionary relationships between the earliest branches of the animal kingdom – bilaterians, cnidarians, ctenophores, sponges and placozoans – are contentious. A new phylogenomic analysis suggests a return to old ideas

Evidence for the derivation of the Drosophila fushi tarazu gene from a Hox gene orthologous to lophotrochozoan Lox5

AbstractThe DNA-binding homeobox motif was first identified in several Drosophila homeotic genes but also in fushi tarazu, a gene found in the Hox cluster yet involved in segmentation, not anteroposterior patterning [1]. Homeotic transformations are not seen in insect ftz mutants, and insect ftz genes do not have Hox-like expression except within the nervous system [2,3]. Insect ftz homeobox sequences link them to the Antp-class genes and Tribolium and Schistocerca orthologs have Antp-class YPWM motifs amino-terminal to the homeobox [2,3]. Orthologs of ftz cloned from a centipede and an onychophoran [4] show that it predates the emergence of the arthropods, but the inability to pinpoint non-arthropodan orthologs suggested that ftz is the product of a Hox gene duplication in the arthropod ancestor [4,5]. I have cloned ftz orthologs from a mite and a tardigrade, arthropod outgroups of the insects [6]. Mite ftz is expressed in a Hox-like pattern, confirming its ancestral role in anteroposterior patterning. Phylogenetic analyses indicate that arthropod ftz genes are orthologous to the Lox5 genes of lophotrochozoans (a group that includes molluscs) [7] and, possibly, with the Mab-5 genes of nematodes and Hox6 genes of deuterostomes and would therefore have been present in the triploblast ancestor

Making Stories: An Investigation of Personal Brand Narratives in the Scottish Craft Microenterprise Sector

This thesis examines the marketing and branding behaviours of a sample of microbusinesses that operate in Scotland’s diverse craft sector by examining brand narratives they create. Context of the sector is first given and demonstrates that this particular topic has received little specific attention in academic literature even though it has been recommended (Fillis 2003a; Fillis 2003b). Such an investigation also offers implications for SME marketing/ entrepreneurship in general, the creative industries in particular and craft brands’ contribution to the overall place branding of Scotland. An empirical methodology is proposed which takes a narrative phenomenological approach, generating narrative texts from depth interviews with creative producers which is subjected to a Grounded Theory approach and narrative analysis in view of craft producer typologies (Fillis 1999; Fillis 2010). The stories of makers are used to generate meaning and outputs to contribute to theory, practice and recommendations for policy. Care is taken to ensure that the testimony of participants is co-created and not entirely the result of the researcher’s interpretation even though this study is interpretive in nature (Rae & Carswell 2000; McAdams 2008; MacLean et al. 2011). Similar to other entrepreneurs or producers in the creative industries, the craft worker in the current era is typified as an individual sole trader who operates in a wider culture, society and economy of increasing complexity and competition (Fraser 2013). This thesis selects those owner/ managers whose businesses rely upon craft practice and are operating in Scotland as its focus, but aims its findings at a wider reach to establish themes for future research to understand how its participants build value into their market offerings by creating personal narratives within larger narratives of craft sector and creative industries discourse. A range of participants from new starts to well-established craft practitioners is featured in the text in order to give depth and breadth to the understanding of current practice in a diverse sector which increasingly interacts with other creative industry sectors (Yair & Schwarz 2011). This thesis posits that creative producers build value through their unique ‘auratic’ persona through their personal brand narrative. This is what differentiates their work and outputs from large corporatized mass-manufacturing systems. The products of individuals’ hand skill may be categorised and classified in many ways – from fine contemporary craft to the vernacular, the utile and that which pays homage to others’ designs. What remains constant, however, is that it emanates from personal identity and the identity of the maker mixing self with story (Leslie 1998). The thesis contributes to the gap in academic marketing literature on microenterprise brand development using the topics of personal narrative, business development, product development, marketing competency/ orientation, and technology use in production and marketing. Additional emergent themes of Microenterprise Social Responsibility, the role of life-work balance of makers parenthood which further ideas of career management in the creative industries are also revealed in the course of this research (see also Summerton 1990; Burroughs 2002; Neilson & Rossiter 2008; McDowell & Christopherson 2009; Banks & Hesmondhalgh 2009). Methodologically, this thesis is hybrid but crucially uses the equipment of story and narrative analysis to offer both insights into practice for the academy and a method that practitioners can use to further marketing development and their brand identity. Through the careful gathering and presentation of various stories – of biography, making and marketing, this thesis presents a current view of craft as created, communicated and exchanged by those working in the field in Scotland today. These case stories act as both informative examples that demonstrate how individual producers create value in their work. The findings are consistent with - but also develop - a maker typology offered by Fillis (1999; 2010) and Burns et al. (2012) thus contributing a methodological and conceptual approach and framework to understand the marketing and branding behaviours of Scottish craft microenterprises (McAuley 1999; Creative and Cultural Skills 2009) but which may also be applied to other types of microenterprise

Sustainability in Nutrition & Dietetics: Where are we now?

With the topic of sustainability becoming a regular feature in all aspects of our lives, this year, the CN Team launched a new CN Award category focusing on sustainability initiatives. In turn, this got us thinking further about the nutrition and dietetic arena as a whole – not just about those of you on the frontline, but also organisations, groups, associations and industry – what action is taking place, and what roles are being developed to actively make nutrition and dietetics more sustainable? So, with this in mind, CN Team members Faye and Jodie sought to do a bit of investigating, in order to discover how the world of nutrition and dietetics is becoming more sustainable! As a result, within this article, we provide a snapshot of initiatives and developments that have, or are, taking place (this is by no means exhaustive), which we hope will further encourage and inspire us all to think more sustainably, and positively acknowledge and recognise what is being done to make an all important difference to the world we live in

Morphological data indicate the subspecies of Leionema elatius (Rutaceae) are not conspecific

Morphological data show that the two subspecies currently assigned to Leionema elatius (Benth.) Paul G.Wilson (Rutaceae), namely L. elatius subsp. elatius and L. elatius subsp. beckleri (F.Muell.) Paul G.Wilson, are not conspecific. Leionema elatius subsp. beckleri is reinstated to the rank of species as L. beckleri (F.Muell.) I.Telford & J.J.Bruhl. The distributions of both species are mapped and their conservation status discussed. Images comparing the morphological attributes of the two species and a table comparing selected attributes of the species and the newly described L. praetermissum P.R.Alvarez & Duretto are presented. A key to species of Leionema found in New South Wales and south-eastern Queensland is provided
