Eight years ago, architects Matias Echanove and Rahul Srivastava set up their offices in Dharavi, a homegrown neighborhood in Mumbai. Instead of denigrating Dharavi as a "slum," Echanove and Srivastava celebrate its vitality and adaptability. They point to the lessons that other cities can learn from Dharavi and demonstrate how "family and community networks can be the foundations" of an urban area.

PurposeNatural hazards such as floods, wildfires and droughts disrupt communities, their economies and environments, and cost millions every year. The existing literature on hazard mitigation shows that community resilience is best achieved when mitigation strategies are integrated with land use and comprehensive planning. The purpose of this paper is to evaluate the strengths and weaknesses of hazard mitigation in local comprehensive plans.Design/methodology/approachThe analysis uses a new plan evaluation protocol that integrates flood, wildfire and drought mitigation to evaluate the plans of the six largest and fastest growing counties in Arizona.FindingsThe study finds that counties do not plan equally well for all hazards, that they tend to plan better for droughts than wildfires and floods, and indicates the need to improve hazard information in plans to support the adoption of mitigation goals, objectives and strategies.Research limitations/implicationsThe research is based on a small sample of comprehensive plans. It focuses on the content of plans rather than the causes that may explain this content or the implementation of the strategies included in the plans. Future research will thus need to analyze larger numbers of plans to identify the determinants of the degree to which comprehensive plans integrate hazard mitigation; and evaluate whether strategies advanced in plans are integrated with other planning documents and implemented.Practical implicationsThe paper makes recommendations to improve the plans evaluated and to guide planners as they develop or revise comprehensive plans in other jurisdictions subject to natural hazards.Originality/valueThe key methodological contribution of the paper is the new plan evaluation protocol designed to assess the wildfire, drought and flood mitigation provisions in comprehensive plans.

We show that a very simple solution to the strong CP problem naturally leads to Dirac neutrinos. Small effective neutrino masses emerge from a type-I Dirac seesaw mechanism. Neutrino mass limits probe the axion parameters in regions currently inaccessible to conventional searches. ; Work supported by the Spanish grants SEV-2014-0398 and FPA2017-85216-P (AEI/FEDER, UE), PROMETEO/2018/165 (Generalitat Valenciana) and the Spanish Red Consolider MultiDark FPA2017-90566-REDC.

BACKGROUND: The Swachh Bharat Abhiyan (SBA) is the most significant cleanliness campaign by the Government of India. Youth are the strong pillars of the development of any country. There is a need to bring a big change to the youth about the cleanliness drive. This study aims to assess the perception of SBA and attitude towards cleanliness among dental students of Kanpur city. MATERIALS AND METHODS: This study is a descriptive, cross-sectional survey, which comprised of 390 undergraduate and postgraduate students. A pretested, self-administered, close-ended questionnaire consisting of 11 questions were included to evaluate the perceptions and attitudes regarding SBA among the dental students. Data were analyzed using IBM Statistical Package for the Social Sciences (SPSS) version 21 (IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp.). Categorical data were compared using the Chi-square test. All values were considered statistically significant for a value of P ≤ 0.05. RESULTS: The results of the study revealed that there is a positive attitude among study participants towards cleanliness, but efforts are still required to emphasize the importance of cleanliness among the many inhabitants. To implement SBA effectively, it is important to highlight the urgent need for public awareness. CONCLUSION: This study found that the majority of the participants was having positive attitude and perception towards SBA, yet initiatives and approaches are still needed to help bring positive actions among those who are reluctant to follow proper cleanliness, sanitation, and hygiene practices.
