Genetic admixture propels invasions of Callosobruchus maculatus across experimental landscapes. In Focus: Wagner, N.K., Ochocki, B.M., Crawford, K.M., Compagnoni, A. & Miller, T.E.X. (2017) Genetic mixture of multiple source populations accelerates invasive range expansion. Journal of Animal Ecology, 86, 21-34. In this issue of Journal of Animal Ecology, Wagner et al. (2017) demonstrate that ge...

We perform a sentiment analysis of all tweets published on the microblogging platform Twitter in the second half of 2008. We use a psychometric instrument to extract six mood states (tension, depression, anger, vigor, fatigue, confusion) from the aggregated Twitter content and compute a six-dimensional mood vector for each day in the timeline. We compare our results to a record of popular event...

US Presidential Election 2012 has been a very tight race between the two key candidates. There were intense battle between the two key candidates. The election reflects the sentiment of the electorate towards the achievements of the incumbent President Obama. The campaign lasted several months and the effects can be felt in the internet and twitter. The presidential debates injected new vigor i...

BACKGROUND Evidence suggests that poor health outcomes and poor work-related health outcomes such as sickness presenteeism are associated with excessive sitting at work. Studies have yet to investigate the relationship between work engagement and occupational sitting. Work engagement is considered to be an important predictor of work-related well-being. We investigated the relationship between ...

Abstract: Seed quality is extremely important for agribusiness, as it can affect the stand establishment, well competitive ability of plant, affecting its yield potential. The aim present work was to evaluate initial development and production performance maize crop a function vigor seed lots. experiment consisted 10 treatments, involving two factors: stands (ideal number plants ideal seeds cor...

With a growing body of genomic information and ever-increasing demands on agriculture, the study of plant genetics is perhaps more urgent than ever. This issue’s Plant Biology Select discusses a technique for site-specific modification of crop plant genomes and describes surprising new evidence that plant tissue grafts may serve as a conduit for the spread of genetic information. Recent work al...

Background Employee engagement is the emotional commitment of the employee towards the organisation. We aimed to analyse baseline work engagement using Utrecht Work Engagement Scale (UWES) at a teaching hospital.   Methods We have conducted a cross-sectional study within the National Health Service (NHS) Teaching Hospital in the UK. All participants were working age population from both genders...

Seeds with high vigor have strong resistance to various adverse environmental conditions. However, little is known about how seed affects the of seeds biotic stress. In this study, newly harvested that had and low vigor, achieved via an artificially accelerated aging treatment, were used in germination test after inoculation Fusariumgraminearum for 24 h. The results showed high-vigor seed-relat...

Abstract: The use of computational tools has become notable in seed quality control to assist confirming lots higher potential. Thus, the aim this study was a approach investigate analysis morphological parameters that characterize primary root emergence evaluation tomato vigor. For purpose, five were analyzed for germination and vigor (seedling seedling images). A parallel made using computer-...
