Housing in the nation’s micropolitan areas: A first look

Micropolitan area is a newly defined unit of analysis for examining housing affordability. Before the creation of micropolitan areas in 2003, U.S. counties were categorized as either metropolitan or nonmetropolitan. The category of micropolitan area allows for a more detailed analysis of housing affordability conditions in areas with populations less than metropolitan areas but more than nonmetropolitan areas. Variables examined in this analysis of micropolitan areas include demographic and housing characteristics. A policy section highlights how the findings from this analysis may be applied to micropolitan geography

What does smart growth mean for housing?

Barely noticed amid the returns from the 1998 midterm elections was a quiet revolution that goes to the heart of how and where Americans live. While most news accounts focused on the high-profile candidate elections, voters across the nation-in Democratic and Republican areas alike-approved more than 160 state and local ballot measures intended to preserve open space and limit urban sprawl. The coalition forming around the idea of limiting sprawl includes environmentalists, farmers, big-city mayors, and some developers. But perhaps most important, the so-called smart growth movement also includes many suburban voters who are fed up with growth. For example, suburbanites in New Jersey-who swept Republican Governor Christine Todd Whitman into office a few years ago on her promise to cut taxes-overwhelmingly supported her proposal to devote about $1 billion a year in taxes and user fees to help preserve half of the state\u27s two million acres of open space over the next ten years. The idea of land preservation is so appealing to many suburbanites that they are willing to pay for it, in contrast with their typical distaste for more taxes

Community acceptance of affordable housing

Despite historically low interest rates, organizations across the nation have become increasingly concerned about the impacts of regulatory constraints and anti-growth sentiments on the availability and cost of housing. This concern is by no means limited to a few “high cost” areas like Boston and San Francisco. It can also be found in Iowa City, where new single-family houses were recently selling from $150,000 to$375,000 (prices readily considered affordable in many larger metropolitan areas) and even in rural areas where spill-over growth and “drive to qualify” solve the commuter’s affordability problem while creating unforeseen affordability problems for the rural native. Today the residents of communities where jobs and population are expanding do not automatically assume that growth is good. Quite the contrary, they raise a skeptical eyebrow and demand “positive” growth. Developers must justify their proposals to the public (particularly neighbors to their developments) throughout zoning applications and subdivision reviews. With inadequate supplies of land zoned at densities to support affordable housing, opponents of development can place substantial pressure on public officials to deny the required zoning or to significantly modify the development, making it more expensive and possibly unfeasible. Neighbors are rarely opposed to development in general, just the specific development near them, a sentiment dubbed “Not in My Back Yard” or NIMBY. Similarly, local public officials are rarely “anti-growth” but want to be sure that new development will have a positive fiscal impact on local government. Since the tax revenue streams associated with residential development are complex and only partially captured by the locality, the presumed (or even estimated) fiscal impact of residential development is often negative

Target marketing can help attract city residents

While suburban growth continues, city living is regaining popularity. It is common knowledge that urban neighborhoods often attract young, single professionals, but a more precise identification of potential city dwellers could help cities understand and develop their comparative advantages. Now, perhaps more than ever, cities need to know which people want to live in them and how their vision of urban life may be accommodated by public policy. A common concern expressed among urban mayors is that the quality of their city services, especially schools, stacks up poorly against that of most suburbs. Improving public education is often cited as the key to attracting suburbanites to cities. Enhancing school quality is indeed an important element in any urban revitalization effort, but it may be less critical than is commonly assumed. Consider that households made up of married couples with children under 18 now account for only a quarter of the nation\u27s total, down from 4 in 10 households in 1970

Evaluation of the HUD Elder Cottage Housing Opportunity (ECHO) program

ECHO housing was introduced in the United States in the 1980s based on a program started in Australia in 1975. An ECHO unit is a small house in which an elderly person resides and which is placed near the home of a host (either relatives or close friends of the elderly person). The purpose of this arrangement is to make it convenient and efficient for the occupants of the host family dwelling to provide assistance to the elderly person residing in the smaller ECHO house. Although ECHO housing provides a means for keeping an elderly resident close to family and friends and may delay or eliminate the necessity of institutional care, administering an ECHO housing program is difficult. Issues surrounding design, quality, maintenance, and oversight vary depending on location and the key groups involved. Problems arise when ECHO units are no longer needed due to death of the resident or other family problems. Relocating units is difficult in terms of where to move them and how to move them without damage. The costs of moving the units add considerably to the overall costs that vary depending on a variety of factors. In addition, zoning is often a barrier that limits ECHO housing to large lots and rural areas

Global assessment of marine plastic exposure risk for oceanic birds

Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, are highly threatened, and cover vast distances during foraging and migration. However, the spatial overlap between petrels and plastics is poorly understood. Here we combine marine plastic density estimates with individual movement data for 7137 birds of 77 petrel species to estimate relative exposure risk. We identify high exposure risk areas in the Mediterranean and Black seas, and the northeast Pacific, northwest Pacific, South Atlantic and southwest Indian oceans. Plastic exposure risk varies greatly among species and populations, and between breeding and non-breeding seasons. Exposure risk is disproportionately high for Threatened species. Outside the Mediterranean and Black seas, exposure risk is highest in the high seas and Exclusive Economic Zones (EEZs) of the USA, Japan, and the UK. Birds generally had higher plastic exposure risk outside the EEZ of the country where they breed. We identify conservation and research priorities, and highlight that international collaboration is key to addressing the impacts of marine plastic on wide-ranging species

Why Are Outcomes Different for Registry Patients Enrolled Prospectively and Retrospectively? Insights from the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF).

Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Heterogeneous catalysis for sustainable biodiesel production via esterification and transesterification

Concern over the economics of accessing fossil fuel reserves, and widespread acceptance of the anthropogenic origin of rising CO2 emissions and associated climate change from combusting such carbon sources, is driving academic and commercial research into new routes to sustainable fuels to meet the demands of a rapidly rising global population. Here we discuss catalytic esterification and transesterification solutions to the clean synthesis of biodiesel, the most readily implemented and low cost, alternative source of transportation fuels to meet future societal demands

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
