Staggered Heavy Baryon Chiral Perturbation Theory

Although taste violations significantly affect the results of staggered calculations of pseudoscalar and heavy-light mesonic quantities, those entering staggered calculations of baryonic quantities have not been quantified. Here I develop staggered chiral perturbation theory in the light-quark baryon sector by mapping the Symanzik action into heavy baryon chiral perturbation theory. For 2+1 dynamical quark flavors, the masses of flavor-symmetric nucleons are calculated to third order in partially quenched and fully dynamical staggered chiral perturbation theory. To this order the expansion includes the leading chiral logarithms, which come from loops with virtual decuplet-like states, as well as terms the order of the cubed pion mass, which come from loops with virtual octet-like states. Taste violations enter through the meson propagators in loops and tree-level terms the order of the squared lattice spacing. The pattern of taste symmetry breaking and the resulting degeneracies and mixings are discussed in detail. The resulting chiral forms are appropriate to lattice results obtained with operators already in use and could be used to study the restoration of taste symmetry in the continuum limit. I assume that the fourth root of the fermion determinant can be incorporated in staggered chiral perturbation theory using the replica method.Comment: 54 pages; v2: corrected discussion in Sec.

Di-photon + Jet Event Structure

New distributions are presented which allow di-photon + jet events to be clearly separated into three classes of events based on the $p_{T}$ of the final state particles and their separation $R$ = $\sqrt{(\Delta y)^{2} + (\Delta \phi)^{2}}$. The analysis used can easily be extended to the case of di-jet + photon.Comment: 6 pages Revtex, uuencoded postscript file containing 3 figure

Positive Points of Bernie\u27s Green New Deal

The Green New Deal will help will create jobs in the energy market. Many people fear that the workers in the coal mines or oil plants will be out of job but this is actually false. The Green New Deal will create jobs in the energy market, all while switching our infrastructure to 100% renewable energy. The Green New Deal is the best way for our country to become more sustainable, modernize our energy infrastructure, and do it without costing americans jobs. First off the Green New Deal will create 20 million new job openings according to Bernie Sanders campaign website. The Green New Deal plans to create enough jobs to not only cover all the fossil fuels workers but also have enough for new workers. Jobs in the renewable energy field also require more people than fossil fuels. According to the Energy Research Center, it takes twice as many humans to run renewable energy than it does for fossil fuels. On top of that, renewables offer a much safer environment than working in the fossil fuel industries. Coal miners that put their health on the line could be working in hydro power plants that require twice as many human positions and less health risks than the mines. The 2017 Energy and Employment report found that there was a sharp decrease in coal energy jobs since 2009, 57% decrease, while wind energy jobs increased by 37% in just two years from 2015 to 2017. This means is that in just a few years renewable energies are already on their way to being huge job creators. According to the 2017 US Energy and Jobs Report, there are approximately 86,000 coal extraction jobs, 12,000 oil extraction jobs, and 393,000 natural gas extraction jobs in the United States. Moving these workers to a safer renewable energy job will in total help almost half a million people live healthier lives. Historically, mass projects like this have been extremely successful. One obvious example would be the New Deal. The new deal introduced dozens of new social programs as well as work programs and reforms in our financial system. This was a massive project that to combat the effects of the Great Depression and it tested the resolve of every American. What the New Deal and Green New Deal have in common is the fact that it will take massive spending and investment. However, the costs tend to pay for themselves over time, usually at least a couple decades. But the New Deal is not the only point in history that took mass mobilization and cooperation. What many people tend to forget is that it created tons of new jobs. The Green New Deal creating 20 million jobs is no different, it creates plenty of new spots. On top of that, fossil fuel workers are guaranteed 5 years of their previous salary, assistance with housing, job training, health care, and retirement support according to Burnie Sanders campaign website. Moving to completely renewable energy is bold but it would finally modernize our system. For instance, France gets 76% of its energy from nuclear power according to the EIA. This is especially impressive because France is the second largest energy consumer per capita. Germany is already utilizing 31% of its total energy production from renewables and 15% from nuclear power in 2015. These two modern countries dwarf the United States. In 2018 the United States only 17% of our total energy came from renewable energy. It is blatantly obvious that it will take drastic measures of the Green New Deal to modernize our energy systems. While the Green New Deal is extremely drastic, it is necessary. History has shown that movements where incredible spending is necessary can work. On top of that, far more jobs will be created along with multiple benefits to fossil fuel workers. The Green New Deal will allow us to catch up to modern renewable energy producers like France and Germany. Most importantly, it will allow us to combat climate change

Safe Environments for Innovation: the development of a new multidisciplinary masters programme

In September 2007, three schools at Northumbria University came together in collaboration to create a Masters Programme in Multidisciplinary Design Innovation (MDI). The lead school was the School of Design working together with the School of Computing, Engineering and Information Sciences (CEIS) and the Newcastle Business School (NBS). This innovation was in response to an emerging understanding within the School of Design of the value of ‘Design-Thinking’ as a multi-disciplinary activity (developed and reinforced through a series of under-graduate pilot projects) and the Cox Review of Creativity in Business: building on the UK’s strengths, which was commissioned by the Chancellor of the Exchequer, Gordon Brown, at the time of the 2005 Budget (Cox, 2005). (Design-Thinking is an approach to viewing business and organisational situations from a more interpretative perspective than that of traditional business analysis (Lester et al,1998)) The programme was launched in September 2008

The relationships and supports that matter to children looked after (CLA) in long term voluntary accommodation (Children Act 1989, s 20)

The overall aim of this practitioner-led research project was to explore relationships and conceptualisations of ‘permanence in foster care’ from the young person’s perspective. A multidimensional conceptualisation of permanence, with a focus on supportive networks, was used to identify the relationships that a group of looked after young people viewed as significant to them and to explore which relationship groups they accessed for social support. Participants were a convenience sample of six (two male, four female) young people (aged 13 – 16) who were voluntarily accommodated (Children Act 1989, s.20) in the long term care of the local authority. Four participants were living with foster carers and two were in residential homes. Participants constructed a personal network map, placing themselves at the centre of a concentric circles diagram and the names of the people in their support network in the surrounding circles. To ascertain participants’ perceptions of who provides what type of support, they were asked how they would respond in three scenarios that were designed to elicit specific measures of social support (affective support, self-affirmation, and instrumental assistance). The results showed that the young people considered a wide variety of relationships as important to them and were able to utilise a range of relationships as sources of social support. Significantly, despite their physical absence, sibling relationships were unanimously viewed as important and appeared to hold the potential to provide much support. This research suggests the potential value in moving beyond physical conceptualisations of permanence and instead adopting a systemic relationships-based approach, which recognises a young person’s entire social network. Recommendations for practice include providing support to strengthen all significant relationships, regardless of their physical presence. This research project hopes to highlight the potentially unique needs of voluntarily accommodated young people. The discussion suggests the importance of reinforcing the implementation of voluntary accommodation as it was intended, as “support for children and families” (Children Act 1989, part 3)
