Book Description
The long-term productivity of forest ecosystems depends on the cycling of nutrients. The effect of carbon dioxide fertilization on forest productivity may ultimately be limited by the rate of nutrient cycling. Contemporary and future disturbances such as climatic warming, N-deposition, deforestation, short rotation sylviculture, fire (both wild and controlled), and the invasion of exotic species all place strains on the integrity of ecosystem nutrient cycling. Global differences in climate, soils, and species make it difficult to extrapolate even a single important study worldwide. Despite advances in the understanding of nutrient cycling and carbon production in forests, many questions remain. The chapters in this volume reflect many contemporary research priorities. The thirteen studies in this volume are arranged in the following subject groups: • N and P resorption from foliage worldwide, along chronosequences and along elevation gradients; • Litter production and decomposition; • N and P stoichiometry as affected by N deposition, geographic gradients, species changes, and ecosystem restoration; • Effects of N and P addition on understory biomass, litter, and soil; • Effects of burning on soil nutrients; • Effects of N addition on soil fauna.

Book Description
The focus of the first half of the book is largely on the current engagement with cycling, challenges faced by existing and would-be cyclists and the issues cycling might address. The second half of the book is concerned with strategies and processes of change. Contributors working from different ontological positions reflect on changing socio-spatial relations to enable the broadest possible participation in cycling.

Book Description
Chronic Prostatitis is a common and debilitating condition affecting 5-12% of men worldwide. The most common form is category III, or Chronic Pelvic Pain Syndrome. Cutting-edge clinical research has led to advancements in the diagnosis and treatment of prostatitis, a group of conditions that is at once extremely common, poorly understood, inadequately treated and under-researched. In Chronic Prostatitis/Chronic Pelvic Pain Syndrome, the author provides today’s most current information covering the four categories of prostatitis (acute, chronic bacterial, CPPS and asymptomatic inflammation). A diverse international group of contributors that includes urologists (academic, primary care and front line private practice), scientists, psychologists, and pain specialists from the National Institutes of Health provide the reader with novel approaches to helping their patients. The chapters in this important new work cover general evaluation of the prostatitis patient, the approach to acute prostatitis, chronic bacterial prostatitis and chronic pelvic pain syndrome, evidence behind individual therapies and ancillary topics such as erectile dysfunction, infertility, the link between chronic prostatitis and prostate cancer, male interstitial cystitis and the potential etiologic role of calcifying nanoparticles. Chronic Prostatitis/Chronic Pelvic Pain Syndrome offers novel approaches to diagnosing this condition as well as providing ways in which to ease the suffering of the patient with prostatitis.

Social justice is a matter of life and death. It affects the way people live, their consequent chance of illness, and their risk of premature death. We watch in wonder as life expectancy and good health continue to increase in parts of the world and in alarm as they fail to improve in others.

Book Description
Background: From the perspective of what is called "vision zero" in Sweden, fatalities and injuries among bicyclists are unacceptable. Despite that, bicyclists constitutes approximately one third of all road user inpatients in Swedish hospitals, which is about the same proportion seen for drivers and passengers of motor vehicles. There are too many bicycle-related head injuries, but the risk of such traumas could be reduced considerably by the use of helmets. Bicycle helmet wearing can be increased by voluntary means, for instance by long-term community-based helmet promotion programs. However, the best effect has been achieved by combining promotion with a compulsory helmet law for all bicyclists, as has been done in Australia, New Zealand, and North America Aim: The general aim of the research underlying this dissertation was to provide further information about the need for increased bicycle helmet use in Sweden, and to determine what measures can lead to more widespread helmet wearing. The four papers included addressed two main questions: (1) What is the need for increased helmet wearing among different categories of bicyclists in Sweden? (2) Is a non-compulsory local bicycle helmet law a realistic alternative to a mandatory helmet law for all bicyclists? Materials and methods: Observational studies of helmet use by bicyclists in Sweden were conducted once a year (average n = 37,031/year) during the period 1988-2002 (paper I). The general trend in observed helmet wearing in different categories of bicyclists was analyzed by linear regression, and the results were used to predict future trends in helmet wearing. Three studies (papers II-IV) were also performed to evaluate a non-compulsory local bicycle helmet "law" in Motala municipality during the study period 1995 to 1998 (papers II-IV). This law was introduced in 1996 and applies specifically to school children (ages 6-12 years), although the intention is to increase helmet use among all bicyclists. Adoption of the law was accompanied by helmet promotion activities. In one of the studies in the evaluation, written material and in-depth interviews (n=8) were analyzed qualitatively to describe the process and structure of development of the Motala helmet law. The other two studies used a quasi-experimental design to assess the impact of the helmet law: one comprised annual observations of helmet wearing among bicyclists in Motala (average n=2,458/year) and control areas (average n=17,818/year); and the other included questionnaire data on attitudes, beliefs, and self-reported behavior of school children in Motala (n=1,277) and control areas (n=2,198). The average response rate was 72.8%. Results and discussion: There was a significant upward trend in helmet use in all categories of bicyclists from 1988 to 2002. Helmet wearing increased from 20% to 35% among children(? 10 years) riding bikes in their leisure time, from 5% to 33% among school children, and from 2% to 14% in adults. Total average helmet use rose from 4% to 17%. However, during the last five years of the study period (1998-2002), there was no upward trend in helmet wearing for any of the categories of bicyclists. If the historic trend in helmet use continues, the average wearing rate will be about 30% by the year 2010. The Motala helmet law was dogged by several problems, mainly during the initiation phase, and some of them led to poor rooting of the law in the schools and indistinct roles and responsibilities of the municipal actors. Despite that, the law initially led to a significant increase in helmet wearing among the primary target group (school children), from a pre-law level of 65% to about 76% six months post-law, whereas thereafter the wearing rate gradually decreased and was at the pre-law level 2 ½ years after the law was adopted. Nonetheless, a weak but significant effect on adult bicyclists remained: the pre-law level of about 2% rose to about 8% at the end of the study period. Only about 10% of bicyclists on bike paths in Motala wore helmets 2 ½ years post-law. The questionnaire study showed one significant effect on school children in Motala two years post-law, namely, a stronger intention to ride bicycles if a national compulsory helmet law was introduced. There was, however, no significant long-term influence on children's attitudes or beliefs about helmet wearing, which agrees with the results of the observational study. General conclusions: It is indeed necessary to increase bicycle helmet wearing in Sweden. Both the current average rate of helmet use and the rate predicted for the near future are far from the goal of 80% that was officially proposed by several years ago. Previous research has shown that, to achieve substantial and sustained bicycle helmet use, it is necessary to use helmet promotion in combination with a national helmet law that is compulsory and applies to all bicyclists. The present evaluation of the non-compulsory local helmet law in Motala indicated that this type of initiative is not a powerful alternative to a mandatory national helmet law. Nevertheless, much has been learned from the initiation and implementation of this local action.

Book Description
The world is urbanizing at an unprecedented rate. It is estimated that in the near future urban landscapes for another ca. 2.7 billion people will be built on planet Earth, approximately converting land equivalent to the size of South Africa. Such land conversion, coupled with citizen densification, increasing in-equalities, shifting diets, and emerging technologies, challenge human well-being and pose ever-increasing demand for resources generated by the Biosphere. This Research Topic concentrates on the various ways urbanization can promote individual well-being (mental, physical, and social health) as well as ecological health (a healthy Biosphere). What kind of affordances for human health promotion can urbanization include? What kinds of affordances for a psychological connection with nature can urbanization include? What kinds of nudges for pro-environmental behavior and consumption (decreasing detrimental consumption behaviors) can be actively designed in urban settings? The Research Topic at hand uses a transactional approach, where an affordance can be understood as a non-deterministic in-situ precondition for a human activity, enabled by relations between abilities of an individual with features of an environment. We encourage a broad definition of the concept of affordances, where ‘the environment’ must not be restricted to the material biophysical environment alone, but also could be combined with social immaterial features. We see that the transactional approach of this Research Topic posits that meaning arises in relations between humans and their environment, that it will be equally applicable to natural and designed environments, and that it doesn’t regard dichotomies like city-contra-nature or social-contra-ecological. Hence, this Research Topic is interested in if the transactional approach can be used as a conceptual tool, not only for promotion of mental, physical, and social health in cities, but simultaneously for unraveling relations at the micro scale in cities which can be used for solutions that also promote a healthy Biosphere.
