A fresh look at manufactured housing

Manufactured housing park cooperatives are becoming popular in New Hampshire, and for good reason. Cooperative ownership brings numerous benefits to residents who previously owned a home on rented land. Paul Bradley tells how these cooperatives have grown and explains what is yet to be done.Housing - New Hampshire

Lack of agreement between measured and self-reported distance from public green parks in Glasgow, Scotland

<p><b>Background:</b></p> <p>Reviews have reported mixed findings for associations between physical activity and proximity to a range of environmental resources. Initially most studies used self reported proximity, but more are now using GIS techniques to measure proximity objectively. We know little about the extent of agreement between self reported and directly measured proximity of the same resource.</p> <p><b>Methods:</b></p> <p>We used previously collected data in a community survey in Glasgow in which 658 respondents aged around 40 and 60 were asked whether they lived within half a mile of a public park. We compared their answers with GIS measures of whether there was a park within a half mile service area of their home (and whether their home was within a half mile crow fly buffer of a park).</p> <p><b>Results:</b></p> <p>Agreement was poor; percentage agreement between measured network distance and reported residence within 0.5 miles of a park was 62.0%, and the kappa value was 0.095. Agreement was no higher than poor in any socio-demographic subgroup, or when using crow fly buffers instead of service areas.</p> <p><b>Conclusion:</b></p> <p>One should be cautious about assuming that respondents' self reports of proximity to a resource are a valid proxy for actual distance, or vice versa. Further research is needed to establish whether actual or self-reported proximity predict physical activity or other behaviours, and if so which is the strongest predictor. Further, qualitative study, also needs to examine the basis of people's judgements about the location of resources, and the possibility that these are shaped by their social and personal significance.</p&gt

Duality in Complex sine-Gordon Theory

New aspects of the complex sine-Gordon theory are addressed through the reformulation of the theory in terms of the gauged Wess-Zumino-Witten action. A dual transformation between the theory for the coupling constant \b > 0 and the theory for \b < 0 is given which agrees with the Krammers-Wannier duality in the context of perturbed conformal field theory. The B\"{a}cklund transform and the nonlinear superposition rule for the complex sine-Gordon theory are presented and from which, exact solutions, solitons and breathers with U(1) charge, are derived. We clarify topological and nontopological nature of neutral and charged solitons respectively, and discuss about the duality between the vector and the axial U(1) charges.Comment: 10 pages, LaTe

b→sγb \rightarrow s \gamma and ϵb\epsilon_b Constraints on Two Higgs Doublet Model

We perform a combined analysis of two stringent constraints on the 2 Higgs doublet model, one coming from the recently announced CLEO II bound on $B(b \rightarrow s \gamma)$ and the other from the recent LEP data on $\epsilon_b$. We have included one-loop vertex corrections to $Z \rightarrow b \overline b$ through $\epsilon_b$ in the model. We find that the new $\epsilon_b$ constraint excludes most of the less appealing window \tan\beta\lsim 1 at $90\%$C.~L. for m_t=150\GeV. We also find that although $b \rightarrow s \gamma$ constraint is stronger for $\tan\beta>1$, $\epsilon_b$ constraint is stronger for \tan\beta\lsim 1, and therefore these two are the strongest and complimentary constraints present in the charged Higgs sector of the model.Comment: LATEX, 9 Pages+1 Figure, the Figure available upon request as a Postscript file, CTP-TAMU-69/9

Potential Improvements to National Park Service Visitor Surveys and Money Generation Modeling in Alaska

This study presents options for improving the use of the Money Generation Model in National Park Service (NPS) land units in Alaska. The Money Generation Model (MGM) is used nationwide to model economic impacts of visitation to public lands, including National Park Units. This analysis identifies potential improvements to the application of the MGM model and visitor survey processes for use in Alaska. Improvements include changes to visitor intercept methods to improve statistical reliability of the sampling process and a more representative sample, changes in the survey instrument to more accurately reflect Alaska visitor travel and expenditure patterns, and better identification of the economic sphere of influence of Alaska national park units.National Park Service, Alaska Director's Office.

Butterfly, Möbius, and Double Burnside algebras of noncyclic finite groups

The double Burnside ring B(G,G) of a finite group G is the Grothendieck ring of finite (G,G)-bisets with respect to the tensor product of bisets over G. Many invariants of the group G, such as the (single) Burnside ring B(G) and the character ring R_C(G), are modules over B(G,G). The double Burnside ring B(G,G) and its various subrings appear as crucial ingredients in functorial representation theory, homotopy theory, and the theory of fusion systems. It is known to be semisimple over rationals if and only if G is cyclic, and in this case an explicit isomorphism onto a direct product of full matrix algebras is given by Boltje and Danz (2013). But not much is know beyond that on the explicit algebra structure. We generalize some techniques of Boltje and Danz for cyclic groups to arbitrary finite groups and as a result obtain an explicit isomorphism of the rational double Burnside algebra of a finite group G into a block triangular matrix algebra when all Sylow subgroups (for all primes) of G are cyclic. Such groups can be characterized as groups G where the Zassenhaus Butterfly lemma gives the meet of two sections (H, K) of G with respect to the subsection relation. Key ingredients are a refinement of the inclusion relation among subgroups of G x G and Möbius inversion over various posets of subgroups.

Ground-water resources of the Oakland Park area of eastern Broward County, Florida

The Oakland Park area obtains its water from the Biscayne aquifer, S composed of very permeable and porous, sandy limestones. The per- 3 meability of the aquifer increases with depth, and wells in the area <\ generally obtain water at depths ranging from 60 to 80 feet, or between S 100 and 200 feet, depending on the quantity of water desired. The data presented in this paper can be used for further development of water and wise management of resources in the area. Large quantities S of ground water are still available at Oakland Park, if salt-water encroachment can be controlled. The data in this study provide the necessary information to begin an effective water management program. (PDF has 49 pages

Ecological consequences of the playgrounds' reconstruction of specialized "park-stadium Khimmash", in Yekaterinburg

In connection with the World Cup in 2018 in the Russian Federation, including the qualifying matches of the World Championship in Yekaterinburg, the Government of the Sverdlovsk Regiondecided to place a training ground on the territory of the "Park-stadium Khimmash". For this purpose, a sports field reconstruction project was created and implemented. The article is devoted to the assessment of negative consequences for plantings of the "Park-stadium Khimmash" in Yekaterinburg as a result of the construction, which led to the destruction of 388 trees, 95 of them are pine trees. The park historically originated on the site of a natural pine plantation. Cutting down so many trees led to further disintegration of the stand. According to the project, the replacement of felled large park trees of pine and birch by willow and apple trees is recommended, which led to the destruction of natural landscapes that have survived in the urban environment. At the same time, not only the aesthetic perception is worsened, but the ecological criteria of the industrial area of the city are also reduced. First of all, the oxygen-producing possibilities of the plantation decreased, which is reflected in the economic assessment of the consequences. © 2019 IOP Publishing Ltd. All rights reserved
