Digital Asset Marketing: Traceability as a competitive advantage in a low carbon economy
The digital world and big data technologies have seen exponential growth in recent years (Ashwin Kumar, 2017). According to International Data Corporation (IDC) corporate spending on Blockchain solutions expected to reach $19 Billion in 2024. Blockchain eliminates the need for a trusted third party where suppliers could transact and trade directly with customers, ensure the data integrity and trace and track assets efficiently (Lacity 2018). Iansiti and Lakhani (2017) demonstrate other characteristics of block chain technology that could stimulate new business models or opportunities. Maroun and Daniel (2019) and Daniel (2021) confirm that there are significant opportunities to adopt blockchain technology in the supply chain. Nascent marketing research, such as Dwivedi et al (2021), suggest a plethora of opportunities for marketing researchers to explore. This research however focuses on the potential of blockchain tokens to trace products through the supply chain and deliver a competitive advantage to companies that seek to promote their carbon and environmental credentials
Crystal Distortion and the Two-Channel Kondo Effect
We study a simple model of the two-channel Kondo effect in a distorted
crystal. This model is then used to investigate the interplay of the Kondo and
Jahn-Teller effects, and also the Kondo effect in an impure crystal. We find
that the Jahn-Teller interaction modifies the characteristic energy scale of
the system below which non-Fermi-liquid properties of the model become
apparent. The modified energy scale tends to zero as the limit of a purely
static Jahn-Teller effect is approached. We find also that the non-Fermi-liquid
properties of the quadrupolar Kondo effect are not stable against crystal
distortion caused by impurities.Comment: 11 page
'Selling it as a holistic health provision and not just about condoms ?' Sexual health services in school settings: current models and their relationship with sex and relationships education policy and provision
In this article we discuss the findings from a recent study of UK policy and practice in relation to sexual health services for young people, based in - or closely linked with - schools. This study formed part of a larger project, completed in 2009, which also included a systematic review of international research. The findings discussed in this paper are based on analyses of interviews with 51 service managers and questionnaire returns from 205 school nurses. Four themes are discussed. First, we found three main service permutations, in a context of very diverse and uneven implementation. Second, we identified factors within the school context that shaped and often constrained service provision; some of these also have implications for sex and relationships education (SRE). Third, we found contrasting approaches to the relationship between SRE input and sexual health provision. Fourth, we identified some specific barriers that need to be addressed in order to develop 'young people friendly' services in the school context. The relative autonomy available to school head teachers and governors can represent an obstacle to service provision - and inter-professional collaboration - in a climate where, in many schools, there is still considerable ambivalence about discussing 'sex' openly. In conclusion, we identify areas worthy of further research and development, in order to address some obstacles to sexual health service and SRE provision in schools
Comparison of computed tomography pulmonary angiography and point-of-care tests for pulmonary thromboembolism diagnosis in dogs
Offering disinclined people the choice between different screening appointments: a randomised online survey
Objectives:
An invitation to cancer screening with a single (fixed) appointment time has been shown to be a more effective way at increasing uptake compared with an invitation with an open (unscheduled) appointment. The present study tested whether offering more than one fixed appointment could further enhance this effect or be detrimental to people’s intention. /
Design:
Experimental online hypothetical vignette survey. /
Methods:
1,908 respondents who stated that they did not intend to participate in Bowel Scope Screening (BSS) were offered either one, two, four or six hypothetical fixed BSS appointments (all of which covered the same time of day to control for individual preferences). /
Results:
Participants who were given more than one appointment to choose from were less likely to intend to book an appointment despite multiple appointments being perceived as more convenient. /
Conclusions:
These results suggest that when it comes to offering people appointments for cancer screening, less (choice) is more, at least if alternatives fail to serve an inherent preference
Cross-modal interference-control is reduced in childhood but maintained in aging: a cohort study of stimulus-and response-interference in cross-modal and unimodal Stroop tasks
Interference-control is the ability to exclude distractions and focus on a specific task or stimulus. However, it is currently unclear whether the same interference-control mechanisms underlie the ability to ignore unimodal and cross-modal distractions. In two experiments we assessed whether unimodal and cross-modal interference follow similar trajectories in development and aging and occur at similar processing levels. In Experiment 1, 42 children(6-11 years), 31 younger adults (18-25 years) and 32 older adults (60-84 years) identified colour rectangles with either written (unimodal) or spoken (cross-modal) distractor-words. Stimuli could be congruent, incongruent but mapped to the same response (stimulus-incongruent), or incongruent and mapped to different responses (response-incongruent), thus separating interference occurring at early (sensory) and late (response) processing levels. Unimodal interference was worst in childhood and old age; however, older adults maintained the ability to ignore cross-modal distraction. Unimodal but not cross-modal response interference also reduced accuracy. In Experiment 2 we compared the effect of audition on vision and vice versa in 52 children (6-11 years), 30 young adults (22-33 years) and 30 older adults (60-84 years). As in Experiment 1, older adults maintained the ability to ignore cross-modal distraction arising from either modality and neither type of cross-modal distraction limited accuracy in adults. However cross-modal distraction still reduced accuracy in children and children were more slowed by stimulus-interference compared with adults. We conclude that; unimodal and cross-modal interference follow different lifespan trajectories and differences in stimulus- and response-interference may increase cross-modal distractibility in childhood
Number counts and clustering properties of bright Distant Red Galaxies in the UKIDSS Ultra Deep Survey Early Data Release
We describe the number counts and spatial distribution of 239 Distant Red
Galaxies (DRGs), selected from the Early Data Release of the UKIDSS Ultra Deep
Survey. The DRGs are identified by their very red infrared colours with
(J-K)AB>1.3, selected over 0.62 sq degree to a 90% completeness limit of
KAB~20.7. This is the first time a large sample of bright DRGs has been studied
within a contiguous area, and we provide the first measurements of their number
counts and clustering. The population shows strong angular clustering,
intermediate between those of K-selected field galaxies and
optical/infrared-selected Extremely Red Galaxies. Adopting the redshift
distributions determined from other recent studies, we infer a high correlation
length of r0~11 h-1 Mpc. Such strong clustering could imply that our galaxies
are hosted by very massive dark matter halos, consistent with the progenitors
of present-day L>L* elliptical galaxies.Comment: 5 pages, 4 figures, revised version accepted to MNRAS.
