    Full Text Available The purpose of this research is to bring out the fact that during the periods of economic crisis, the black market finds a warm place to develop and even to diversify the ways of expressing. Based on some data of the National Institute of Statistics and the Organization for Economic Co-operation and Development (OECD1 , I’m trying to prove the fact that during the last two years while the world economic crisis has occurred, the black market has been increasing and there have been new forms of expressing this phenomenon. Although there are some positive ways of this phenomenon, on the whole, the increasing of the black market percent of GDP represents a wound within a healthy economy, which if it cannot be stopped at least to be reduced. This work intends to make radiography of the present economic society, a period of economic crisis, during which the black market has found a warm place to express and extend, in most of the countries, including the developed ones, this phenomenon has reached alarming limits.

    Background . Recent research suggests that the health gain from economic resources and psychological assets may be systematically larger for Whites than Blacks. Aim . This study aimed to assess whether the life expectancy gain associated with social contacts over a long follow up differs for Blacks and Whites. Methods . Data came from the Americans' Changing Lives (ACL) Study, 1986-2011. The sample was a nationally representative sample of American adults 25 and older, who were followed for up to 25 years ( n = 3361). Outcome was all-cause mortality. The main predictor was social contacts defined as number of regular visits with friends, relatives, and neighbors. Baseline demographics (age and gender), socioeconomic status (education, income, and employment), health behaviors (smoking and drinking), and health (chronic medical conditions, obesity, and depressive symptoms) were controlled. Race was the focal moderator. Cox proportional hazard models were used in the pooled sample and based on race. Results . More social contacts predicted higher life expectancy in the pooled sample. A significant interaction was found between race and social contacts, suggesting that the protective effect of more social contacts is smaller for Blacks than Whites. In stratified models, more social contacts predicted an increased life expectancy for Whites but not Blacks. Conclusion . Social contacts increase life expectancy for White but not Black Americans. This study introduces social contacts as another social resource that differentially affects health of Whites and Blacks.

    Linich, Michael

    The molecular biology revolution has turned the classification of life on its head. Is Whittaker's five-kingdom scheme for the classification of living things no longer relevant to life science education? Coupled with this is the discovery that most microscopic life cannot yet be brought into culture. One of the key organisms making this knowledge possible is Methanococcus jannishi a microorganism found in black smokers. This workshop presents the development of the Universal Tree of Life in a historical context and then links together major concepts in the New South Wales senior science programs of Earth and Environmental Science and Biology by examining the biological and geological aspects of changes to black smokers over geological time.

  6. Economic antecedents of prone infant sleep placement among black mothers.

    Bruckner, Tim A

    2008-09-01

    Black infants die from sudden infant death syndrome at twice the incidence observed among non-Hispanic white infants. Explanations for this disparity include a two-fold greater prevalence of prone (i.e., stomach) infant sleep placement among black caregivers. I test the hypothesis that the contraction of state economies may contribute to this disparity by increasing the risk of prone infant sleep placement among black mothers. I retrieved data from the Bureau of Labor Statistics employment series and 33,518 black mothers in 26 states participating in the 1996-2002 Pregnancy Risk Assessment Monitoring System. I use weighted multivariable analyses to control for individual characteristics and state and time trends. Black mothers exhibit an elevated risk of reporting prone placement one month following statewide declines in employment (adjusted odds ratio for a one percent decline = 1.11, 95% CI 1.01 to 1.22). This risk remains elevated after control for individual variables. In contrast, I find no association between the economy and prone placement among white mothers. Statewide economic decline may reduce adherence to the recommended non-prone infant sleep position among black, but not white, mothers. Additional research among black caregivers should determine which mechanisms connect economic downturns to prone infant sleep placement.

  10. Economic modeling for life extension decision making

    Farber, M.A.; Harrison, D.L.; Carlson, D.D.

    1986-01-01

    This paper presents a methodology for the economic and financial analysis of nuclear plant life extension under uncertainty and demonstrates its use in a case analysis. While the economic and financial evaluation of life extension does not require new analytical tools, such studies should be based on the following three premises. First, the methodology should examine effects at the level of the company or utility system, because the most important economic implications of life extension relate to the altered generation system expansion plan. Second, it should focus on the implications of uncertainty in order to understand the factors that most affect life extension benefits and identify risk management efforts. Third, the methodology should address multiple objectives, at a minimum, both economic and financial objectives

    1975-01-01

    This is an investigation into the assumption that uncontrolled economic growth puts a burden on the natural environment and lowers the quality of life. This analysis of the natural, technical, economic, and social environment answers the following questions: 1) which development will production and consumption take up to the year 2000; 2) extent of environmental burden to be expected as a result thereof; 3) influence of needs and valid standard of values thus prevailing; 4) administrative measures for environmental policies; 5) influence of environmental policies on the quality of life; 6) possibility of economic growth while the natural environment is sufficiently protected at the same time. The man-environment model presented elucidates the interrelations between economic development and the natural and social environment; it checks the effectiveness of alternate environmental protection measures.

    2017-11-01

    Full Text Available In the first part of the article I have dealt with the role and place of behavioral economics in the economic sciences. Classical economic theories are criticized by the behavioral economy. We think we are rational beings and that we make logical decisions based on the information we have at our disposal. In fact, we have our own cognitive limitations that can lead to hasty decisions or confusing judgments; the real individual is a complex person, with actions that result in failures and incomprehensible behaviors for the economics Behavioral economics is trying to explain why individuals often make irrational choices, and why decisions they take do not follow exactly the patterns predicted by classical and neoclassical economic models. This paper is trying to assess the individual behavior involved in the decision making process in the university space. This article describes aloso a series of experiments on behavioral economics. The experiments are from university life and contest the hypothesis of the perfectly rational person's existence in making decisions and the neoclassical economic theories and models that are based only on the premise of the existence of homo oeconomicus rationalis. Observations and experiments conducted with students at Constantin Brancusi University in Târgu-Jiu are relevant in challenging the hypothesis of perfect rationality, preference stability, perfect information and market efficiency. The research method used in this article is the experiment. Study results are useful for academic management.

  14. Judaism and Economics: The Link between Judaism and Economic Life

    Directory of Open Access Journals (Sweden)

    Stanisław Fel

    2014-09-01

    Full Text Available This article deals with the relationship of Judaism to economic activity. The subject is the typical approach of Jewish ethical thought, concerning the understanding of money, wealth, jobs and economic initiatives. Issues related to fundamental economic life are shown to be covered in the books that the Jewish community considers sacred. Particularly important are the Old Testament and the Talmud. Also important are references to the cultural interpretation of Judaism, including the classical works on the subject – Jacques Attali and Werner Sombart. The key concept is the subject of “wealth,” the meaning of which is derived from the Bible’s Book of Exodus and the Talmud. Finally, the foundations for Jewish economic thought can be expressed as the product of an embedded culture, which is founded on religion, in which property acquires ethical legitimacy. The argument is crowned with historical examples of the noble economic activity of the Jewish people, which also give evidence of the interrelatedness of religion and the proper use of wealth.

  16. From Life Cycle Costing to Economic Life Cycle Assessment—Introducing an Economic Impact Pathway

    Directory of Open Access Journals (Sweden)

    Sabrina Neugebauer

    2016-04-01

    Full Text Available Economic activities play a key role in human societies by providing goods and services through production, distribution, and exchange. At the same time, economic activities through common focus on short-term profitability may cause global crisis at all levels. The inclusion of three dimensions—environment, economy, and society—when measuring progress towards sustainable development has accordingly reached consensus. In this context, the Life cycle sustainability assessment (LCSA framework has been developed for assessing the sustainability performance of products through Life cycle assessment (LCA, Life cycle costing (LCC, and Social life cycle assessment (SLCA. Yet, the focus of common economic assessments, by means of LCC, is still on financial costs. However, as economic activities may have a wide range of positive and negative consequences, it seems particularly important to extend the scope of economic assessments. Foremost, as the limitation to monetary values triggers inconsistent implementation practice. Further aspects like missing assessment targets, uncertainty, common goods, or even missing ownership remain unconsidered. Therefore, we propose economic life cycle assessment (EcLCA for representing the economic pillar within the LCSA framework, following the requirements of ISO 14044, and introducing an economic impact pathway including midpoint and endpoint categories towards defined areas of protection (AoPs. We identify important target ratios by means of economic AoPs, which drive economic activities on the macro- and microeconomic level. Furthermore, we provide suggestions for midpoint and endpoint indicators representing the defined categories. With the presented EcLCA framework, a first step towards the inclusion of economic impacts within LCSA has been made. Relations between economic activities and resulting consequences are displayed, going beyond the cost-driven view of classical LCC. Further research and fine-tuning of

    South Africa has experienced great change and progress in the ten years since the end of apartheid and the inauguration of its first democratic government. Back in 1994, many were concerned about whether such a young and fragile democracy could survive. The new government needed to unify the country, while bringing about the significant change necessary to address the massive racial inequality at the heart of the apartheid system. The article explains actions and initiatives taken under the Black Economic Empowerment (BEE) programme, one of which is the establishment of Eyesizwe Coal. 2 figs., 1 photo.

  18. FOREIGN DIRECT INVESTEMENTS FLOWS IN BLACK SEA ECONOMIC COOPERATION

    2011-04-01

    Full Text Available We live in a time when the world’s economy is in a constantly change. Foreign direct investments flows are in actual economy one of the most dynamic and prospective part of the world’s economy being in a continuous globalization. These international financial flows determine the traders who take part at the world’s economy to know to adopt a specific management in the international affairs field. We are viewers of an unprecedented expansion of foreign direct investments. The main objective of the paper is to analyze the foreign direct investments flows in Black Sea Economic Cooperation. This study is based on UNCTAD reports and on an econometrical model which gives us the possibility to create different analysis concerning FDI flow in this cooperation. So we defined a simple regression model, in which the dependent variable is represented by Nominal and real GDP, total and per capita, variable explicated by FDI flows, using as method the Least Squared, including 19 observations. Through this paper, we tried to illustrate the relation between the FDI flows and the economic growth rate in the past years inRomania, member of Black Sea Economic region. In line with a general upward trend in FDI to Central and Eastern Europe, inward FDI to the Russian Federation held steady between 1998 and 2001, at an annual average of $2.8 billion. In Black Sea Economic region, Russian average is the biggest one, Russia being a leader country in warding FDI. The Russian Federation is by far the leading investor country in the region, accounting for more than 75% of its annual outflows. Inward and outward direct investments flows in Russia have reached in 2009 an amount of $38,722 billion. In Romania, following years of stagnation at very low levels, 1991 to 1997, FDI flows reached $1.1 billion in 2002. Inflows to Bulgaria peaked at $1 billion in 2000; the surge is largely due to flows from developed countries. Inward and outward direct investments flows in

  19. Life Events and Black-White Differences in Adult Children's Financial Assistance to Mothers.

    Parents who experience life events with negative economic consequences may rely on adult children for financial assistance. This study provided national estimates of Black and White mothers' financial help from adult children. It also examined whether the Black-White difference in the likelihood of a mother's receipt of financial assistance persisted after accounting for life events reflecting parental need and children's ability to provide help. The Health and Retirement Study was used to examine late middle aged (51-70) Black and White mothers' financial help from adult children. Cross-sectional point estimates of financial help from noncoresident and coresident children were based on pooling these data. Random effects logistic regression at the mother-wave level was used to estimate the likelihood of receipt of financial assistance from noncoresident children. On average, 9% (8%) of Blacks and 3% (4%) of Whites reported help from noncoresident (coresident) children in a given interview wave, but Blacks received lower amounts. Changes signifying greater parental financial need and noncoresident children's greater resources were positively associated with receiving financial help from noncoresident children. After accounting for these factors, race differences remained. Black mothers are more likely to rely on children for financial help than Whites. Since this help hinges on the ability of their children to provide, the strength of Blacks' economic safety net as they age also depends on the socioeconomic well-being of the younger generation. © The Author 2017.

    This paper discusses the need for changing priorities in plant life management. Following a brief review of the major world-wide trends which are affecting plant life management, the fundamental nature of the plant life management process itself is considered. It is suggested that a consistent approach to the management of economic and safety risk can provide a mechanism for continuous improvement of the process. One such approach, Techno-Economic Ageing and Maintenance Management - TEAMM, is described. The tool required for this process are discussed and examples given of its application to ageing plant and evaluation of life extension. 2 figs

    This article examines how differences in longevity over time and across groups add to the typical measures of economic progress and intergroup differentials. We focus on gains for and differences between groups defined both by race (black and white) and by gender, relying on willingness to pay as our measure of the economic value of gains in longevity. Measured at birth, the gains for white males between 1968 and 1998 were about 245,000 dollars per person, while the gains for black males were far larger, about 390,000 dollars per person. The gains for women were somewhat smaller, with white females gaining about 150,000 dollars per person and black females gaining about 305,000 dollars per person. Our estimates suggest that differences in income explain about 1/3 to 1/2 of the current black-white gap in longevity.

    The hemicelluloses fraction of black liquor is an underutilized resource in many chemical pulp mills. It is possible to extract and separate the lignin and hemicelluloses from the black liquor and use the hemicelluloses for biochemical conversion into biofuels and chemicals. Precipitation of the lignin from the black liquor would consequently decrease the thermal load on the recovery boiler, which is often referred to as a bottleneck for increased pulp production. The objective of this work is to techno-economically evaluate the production of sodium-free lignin as a solid fuel and butanol to be used as fossil gasoline replacement by fractionating black liquor. The hydrolysis and fermentation processes are modeled in Aspen Plus to analyze energy and material balances as well as to evaluate the plant economics. A mathematical model of an existing pulp and paper mill is used to analyze the effects on the energy performance of the mill subprocesses. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The aim of this study is to explore the relationship between renewable energy consumption and economic growth within the framework of traditional production function for the period of 1990–2012 in 9 Black Sea and Balkan countries. For this purpose, we use panel cointegration, co-integration estimate methods and heterogeneous panel causality estimation techniques. The study has concluded that there is a long term balance relationship between renewable energy consumption and economic growth and renewable energy consumption has a positive impact on economic growth. Heterogeneous panel causality analysis results support growth hypothesis in Bulgaria, Greece, Macedonia, Russia and Ukraine; feedback hypothesis in Albania, Georgia and Romania; neutrality hypothesis in Turkey and according to the panel data set including all nine countries the results support feedback hypothesis. With the findings, it was concluded that there is a significant impact of renewable energy consumption on economic growth in Balkan and Black Sea Countries. - Highlights: • Explores the impact of renewable energy on economic growth in Black Sea and Balkan countries. • Employs panel cointegration and heterogeneous causality analyses. • Finds significant effect of renewable energy consumption on economic growth. • Finds bidirectional causality between renewable energy consumption and economic growth for the whole panel.

    In USA where the development of nuclear power was started early, the life of nuclear power plants expires successively around the turn of century, and the serious hindrance to electric power supply is feared. Therefore, the research for extending 40 year approved period of operation is in progress. By the extension of life of nuclear power plants, huge cost reduction is estimated as compared with the construction of new plants. However, due to the rise of the cost for the life extension, there were the cases of forced decommissioning. In this book, the present state of the life extension of nuclear power stations, the economical assessment and analysis of the life extension by DOE, the economical assessment by MIDAS method of Electric Power Research Institute, the economical assessment by cost-benefit method of Northern States Power Co., the assessment of the long term operation possibility of nuclear power stations, the economical assessment system for the life extension in Japan, the present state of the decommissioning of nuclear power stations and that in USA, Canada and Europe, the assessment of the decommissioning cost by OECD/NEA, and the decommissioning cost for thermal power stations are described.

    Census data from 1940-90 show that skill demands due to technological change accelerated inequality for less skilled workers, partly accounting for the slowed economic progress of black men. It is not female and immigrant labor market entrants, but increased competition from middle-skilled white men that appears to have adverse influence on black…

    1998-01-01

    NEA provides an opportunity for international exchange of information on the economics and policies of nuclear plant life management for governments and plant owners. The NEA Secretariat is finalising the 'state-of-the-art report' on the economics and policies of nuclear plant life management, including the model approach and national summaries. In order to meet power supply obligations in the early 2000, taking into account energy security, environmental impact, and the economics of nuclear power plants whose lives have been extended, initiatives at national level must be taken to monitor, co-ordinate, and support the various industry programmes of nuclear plant life management by integrated and consistent policies, public acceptance, R and D, and international co-operation. Nuclear power owners should establish an organisation and objectives to carry nuclear plant life management in the most economic and smoothest way taking into consideration internal and external influences. The organisation must identify the critical item and the ageing processes, and optimise equipment reliability and maintenance workload. (author)

    This article examines the individual economic returns to volunteering during different stages of working life. The article uses a unique panel dataset created by combining rich survey data from Denmark with information on wages from administrative registers covering the period from 2004 to 2012....... Applying a two-way fixed effects regression model that controls for both period-specific and individual-specific effects, the article finds that for labour market entrants and for people in the early stages of their working life, an additional year of volunteer work experience yields a significant positive...... return. However, the economic returns to volunteer work experience decrease as a function of professional labour market experience. For people with more than six years of professional labour market experience, the economic returns to volunteer work experience are insignificant. On these grounds...

    Full Text Available Topicality. The Black Sea region is very dynamic in terms of economic development, security problems and interstate relations. All of the countries in this region are heterogeneous but energy issue plays a pivotal role in their foreign policy priorities. It is the only one common denominator that can both foster cooperation and catalyze conflict in the Black Sea basin. The problem of transporting energy has an impact not only on the Black Sea countries, but also on the Southeastern Europe, Russia, the Caspian Sea, Middle East, and ultimately the European consuming markets. Thus, the issue of energy transition needs the experts’ and scientists’ attention fixed on the Black Sea region in order to come together facing the latter-day challenges. The energy challenge has a multi-dimensional nature. Aim. Thus, this paper aims to provide an overview of the energy transaction issues focusing on the economic effects of the most important gas pipelines within the Black Sea region. Particular attention is going to be paid to the problem of the energy routes’ diversification and pipelines which connect the carbon-rich countries of the Middle East and Caspian region and Europe. Also, it is aimed to give a comprehensive analysis of the energy challenge within the Black sea region, focusing on energy efficiency of the gas pipelines which go through this extremely important energy hub. Methods - scientific methods of data analysis, historical and statistical overview, predictive analysis qualitative indicators, comparative method, method of description, case study. Results. The creation of a stable markets, interconnected and transparent natural gas supply would largely counteract the risks. The flexibility transport infrastructure, numerous and capable pipelines, underground storage capacities and their management may play an important role in the sector’s ability to manage supply shocks.

    2015-01-01

    This study aimed to investigate the additive effects of socio-economic factors, number of psychiatric disorders, and religiosity on suicidal ideation among Blacks, based on the intersection of ethnicity and gender. With a cross-sectional design, data came from the National Survey of American Life, 2001-2003, which included 3570 African-American and 1621 Caribbean Black adults. Socio-demographics, perceived religiosity, number of lifetime psychiatric disorders and lifetime suicidal ideation were measured. Logistic regressions were fitted specific to groups based on the intersection of gender and ethnicity, while socioeconomics, number of life time psychiatric disorders, and subjective religiosity were independent variables, and lifetime serious suicidal ideation was the dependent variable. Irrespective of ethnicity and gender, number of lifetime psychiatric disorders was a risk factor for lifetime suicidal ideation (odds ratio [OR] ranging from 2.4 for Caribbean Black women to 6.0 for Caribbean Black men). Only among African-American men (OR = 0.8, 95% confidence interval = 0.7-0.9), perceived religiosity had a residual protective effect against suicidal ideation above and beyond number of lifetime psychiatric disorders. The direction of the effect of education on suicidal ideating also varied based on the group. Residual protective effect of subjective religiosity in the presence of psychiatric disorders on suicidal ideation among Blacks depends on ethnicity and gender. African-American men with multiple psychiatric disorders and low religiosity are at very high risk for suicidal ideation.

    2012-01-01

    Background A relationship between current socio-economic position and subjective quality of life has been demonstrated, using wellbeing, life and needs satisfaction approaches. Less is known regarding the influence of different life course socio-economic trajectories on later quality of life. Several conceptual models have been proposed to help explain potential life course effects on health, including accumulation, latent, pathway and social mobility models. This systematic review aimed to assess whether evidence supported an overall relationship between life course socio-economic position and quality of life during adulthood and if so, whether there was support for one or more life course models. Methods A review protocol was developed detailing explicit inclusion and exclusion criteria, search terms, data extraction items and quality appraisal procedures. Literature searches were performed in 12 electronic databases during January 2012 and the references and citations of included articles were checked for additional relevant articles. Narrative synthesis was used to analyze extracted data and studies were categorized based on the life course model analyzed. Results Twelve studies met the eligibility criteria and used data from 10 datasets and five countries. Study quality varied and heterogeneity between studies was high. Seven studies assessed social mobility models, five assessed the latent model, two assessed the pathway model and three tested the accumulation model. Evidence indicated an overall relationship, but mixed results were found for each life course model. Some evidence was found to support the latent model among women, but not men. Social mobility models were supported in some studies, but overall evidence suggested little to no effect. Few studies addressed accumulation and pathway effects and study heterogeneity limited synthesis. Conclusions To improve potential for synthesis in this area, future research should aim to increase study

  14. Science identity possibilities: a look into Blackness, masculinities, and economic power relations

    Rosa, Katemari

    2018-02-01

    This forum paper dialogues with Sheron Mark's A bit of both science and economics: a non-traditional STEM identity narrative. In her paper, she discusses the development of a Science, Technology, Engineering, and Mathematics (STEM) identity by a young African American male during an informal STEM for Social Justice Program. Here, the discussion focuses on Black masculinities, identity formation, and the role of science educators in making STEM fields a welcoming place for young Black men. Drawing from Mark's data and discussion, this paper is a dialogue between science identity possibilities in the United States and in Brazil when we look at the intersections of race, gender, and socioeconomic status. Using the shared colonial past of both countries a connection is established to address race relations within science education. The main argument in this paper is that racism can no longer be denied and dismissed by the science education community worldwide and that intersectional approaches are needed to face this issue.

    2018-04-01

    New data reveal significant variation in economic mobility outcomes across U.S. localities. This suggests that social structures, institutions, and public policies-particularly those that influence critical early-life environments-play an important role in shaping mobility processes. Using new county-level estimates of intergenerational economic mobility for children born between 1980 and 1986, we exploit the uneven expansions of Medicaid eligibility across states to isolate the causal effect of this specific policy change on mobility outcomes. Instrumental-variable regression models reveal that increasing the proportion of low-income pregnant women eligible for Medicaid improved the mobility outcomes of their children in adulthood. We find no evidence that Medicaid coverage in later childhood years influences mobility outcomes. This study has implications for the normative evaluation of this policy intervention as well as our understanding of mobility processes in an era of rising inequality.

    Dying patients and their families often face an added burden of economic hardship, especially if they have become ill in the years before expected retirement. In Australia, patients can fall through the cracks of the national system of social protection because there are gaps in the access to and provision of healthcare and social assistance at the end of life. A mixed-method, prospective case study of individuals and their family carers, recruited from a specialist palliative care service in Melbourne, Australia, is presented. Participants were interviewed and followed up over 6 months and completed a 2-week diary of all services used and out-of-pocket costs. Mean out-of-pocket spending was $A369 per month (median: $A176, IQR: 356) ($A1=US$1=€0.73=£0.62; January 2011). Households with economic hardship were more likely to have a patient who was male, had ceased paid employment earlier than expected due to illness, reported a reduction in income due to illness, had less access to financial resources and used significantly fewer health-related community services. Three factors shaped the participants' experience of hardship: (1) the premature loss of employment capacity and income; (2) the affordability of care and; (3) a welfare system that could not accommodate their complex needs. These results demonstrate the multidimensional nature of the economic burden experienced at the end of life and imply the need for nuanced solutions to better support patients and their families. If terminally ill people wish to die at home and are to be supported to do so, policies must take account of the shift in economic burden from the health system onto families.

Corruption, fraud and other criminal phenomena blossom in Russia, since there is no struggle against them. State machinery bureaucrats consume 40% of the GIP. Modernization of the country’s political and economic life is possible only through fundamental break of current public relations and taking new orientation on the basis of a combination of capitalist and socialist features.

    2018-02-01

    Full Text Available Different economic development strategies may result in varied socioeconomic and environmental synergies or tradeoffs, suggesting an opportunity for environmentally conscious planning. To understand such synergies or tradeoffs, a dynamic environmental life cycle assessment was conducted for eleven groups of New Hampshire industries. Historical state level Gross Domestic Product (GDP-by-industry data was combined with economic input-output analysis to calculate the direct and life cycle energy use, freshwater use, greenhouse gas emissions, and eutrophication potential of each industry on a yearly basis for the period of 1997–2012. The future development of agriculture, traditional manufacturing, high tech, and tourism industries were investigated based on government projections. Total life cycle impacts of the 11 industries were found to represent around three to seven times those of direct impacts, indicating the significance of the supply chain impacts. Traditional manufacturing has the highest life cycle impacts even though it contributes to less than 10% of the state GDP. Future development of high tech was found to be the best strategy to increase GDP while imposing the least additional environmental impacts. Tourism presents relatively high impacts in terms of freshwater use and eutrophication potential, and a change in recreational style might be able to reduce its impacts.

    Background The annual cost of providing care for patients in their last year of life is estimated to account for approximately 9% of the Ontario health care budget. Access to integrated, comprehensive support and pain/symptom management appears to be inadequate and inequitable. Objective To evaluate the cost-effectiveness of end-of-life (EoL) care interventions included in the EoL care mega-analysis. Data Sources Multiple sources were used, including systematic reviews, linked health administration databases, survey data, planning documents, expert input, and additional literature searches. Review Methods We conducted a literature review of cost-effectiveness studies to inform the primary economic analysis. We conducted the primary economic analysis and budget impact analysis for an Ontario cohort of decedents and their families and included interventions pertaining to team-based models of care, patient care planning discussions, educational interventions for patients and caregivers, and supportive interventions for informal caregivers. The time horizon was the last year of life. Costs were in 2013 Canadian dollars. Effectiveness measures included days at home, percentage dying at home, and quality-adjusted life-days. We developed a Markov model; model inputs were obtained from a cohort of Ontario decedents assembled from Institute for Clinical Evaluative Sciences databases and published literature. Results In-home palliative team care was cost-effective; it increased the chance of dying at home by 10%, increased the average number of days at home (6 days) and quality-adjusted life-days (0.5 days), and it reduced costs by approximately $4,400 per patient. Expanding in-home palliative team care to those currently not receiving such services (approximately 45,000 per year, at an annual cost of $76–108 million) is likely to improve quality of life, reduce the use of acute care resources, and save $191–$385 million in health care costs.

    Full Text Available Aquaculture industry, like most other industries, has a very powerfull correlation with the economical domain. Being an economic activity that generates profit, practicing fish farming aims profit maximization. The present study gives information regarding the economical indicators and also makes a cost structure analysis of five groups of fish farms from Southeastern Coast of the Black Sea: homestead fish farms, small scale fish farms, middle scale fish farms, big scale fish farms and floating cages. The fish farms were classified in this way by their production capacity. In order to collect data, the most representative fish farms for each group were selected and face to face interviews were made for every one of them. Data related to their source of financing, initial investment, labour costs, selling prices, feed costs and other operational costs were collected, arranged, structured and analyzed and a series of economic indicators as gross production value, gross margin, breakeven quantity, specific investment, profit, profitability ratio, rate of return or labour productivity were calculated. As a result, it was observed that fish production capacity has a big influence over the rate of return, middle scale fish farms being the most profitable, followed closely by small scale fish farms.

    Solidification (making concrete) and vitrification (making glass) are frequently the treatment methods recommended for treating inorganic or radioactive wastes. Solidification is generally perceived as the most economical treatment method, whereas vitrification is considered (by many) as the most effective of all treatment methods. Unfortunately, vitrification has acquired the stigma that it is too expensive to receive further consideration as an alternative to solidification in high volume treatment applications. Ex situ solidification and vitrification are the competing methods for treating in excess of 450,000 m 3 of low-level radioactive and mixed waste at the Fernald Environmental Management Project (FEMP or simply, Fernald) located near Cincinnati, Ohio. This paper s a detailed study done to: compare the economics of the solidification and vitrification processes; determine if the stigma assigned to vitrification is warranted; determine if investing millions of dollars into vitrification development, along with solidification development, at Fernald is warranted. Common parameters were determined and detailed life-cycle cost estimates were made. Incorporating the unit costs into a computer spreadsheet allowed 'what if' scenarios to be performed. Some scenarios investigated included variation of: remediation times, amount of wastes treated, treatment efficiencies, electrical and material costs and escalation

    Socio-economic status (SES) has been associated with measures of diet quality; however, such measures have not directly captured overall eating practices in individuals. Based on the factor analysis of fifty-six food groups from FFQ, associations between patterns of food consumption and SES were examined in a nationwide sample of 17,062 black (34·6%) and white participants (age >45 years) from the REasons for Geographic And Racial Differences in Stroke (REGARDS) study. Logistic regression models adjusted for age, sex, racial group and geographic region were used to examine adherence to five emergent dietary patterns (convenience, plant-based, sweets/fats, southern and alcohol/salads) according to four levels each of individual education, household income and community-level SES. Further models assessed adherence to these dietary patterns by racial group, and an overall model including both racial groups examined whether the relationships between SES and adherence to these dietary patterns differed among black and white participants. For all the three measures of SES, higher SES had been associated with greater adherence to plant-based and alcohol/salads patterns, but lower adherence to sweets/fats and southern patterns. Statistically significant differences between black and white participants were observed in the associations between household income and adherence to alcohol/salads, individual education and adherence to plant-based and sweets/fats, and community SES and adherence to convenience patterns. As adherence to dietary patterns has been shown to be associated with health outcomes in this population (e.g. stroke), the present study offers valuable insight into behavioural and environmental factors that may contribute to health disparities in the diverse US population.

    Disparate birth outcomes among Black women continue to be a major public health problem. Whereas prior research has investigated the influence of stress on Black women's birth outcomes, few studies have explored how stress is experienced among Black women across the life course. The objectives of this study were to describe the experience of stress across the life course among Black women who reported a history of fetal or infant death and to identify stressful life events (SLE) that may not be represented in the widely used SLE inventory. Using phenomenological, qualitative research design, in-depth interviews were conducted with six Black women in Kansas who experienced a fetal or infant death. Analyses revealed that participants experienced multiple, co-occurring stressors over the course of their lives and experienced a proliferation of stress emerging in early life and persisting into adulthood. Among the types of stressors cited by participants, history of sexual assault (trauma-related stressor) was a key stressful life event that is not currently reflected in the SLE inventory. Our findings highlight the importance of using a life-course perspective to gain a contextual understanding of the experiences of stress among Black women, particularly those with a history of adverse birth outcomes. Further research investigating Black women's experiences of stress and the mechanisms by which stress impacts their health could inform efforts to reduce disparities in birth outcomes. An additional focus on the experience and impact of trauma-related stress on Black women's birth outcomes may also be warranted.

    Full Text Available Corporate social responsibility (CSR has recently received considerable attention in literature. One of the vehicles by which companies can conform to CSR in South Africa is Black Economic Empowerment (BEE. In this regard, BEE has been employed to assist previously disadvantaged groups of investors obtain a larger share of the equity of South African listed companies. The question has often been asked whether the announcement of BEE transactions by listed companies increases shareholder wealth. This article tries to answer this question by examining the share performance of 125 BEE transactions involving 95 companies during the period January 2002 to July 2006. The results indicate a positive relation between BEE transaction announcements and shareholder wealth creation, but only during the last part of the period covered by the study.

    As part of a longitudinal project on Quality of Life, a study was undertaken to extend the applicability of the 5-item Satisfaction With Life Scale, developed in the USA, in South Africa. Data on basic sociodemographic characteristics, the scale, and the 10-item Rosenberg Self-esteem scale were available for 360 Black South Africans (151 men and 209 women), ages 21 to 83 years (M = 38.6 yr., SD = 10.3). Factor analysis applied to scale scores gave two factors, accounting for 71% of the variance. Factor I was loaded by 10 Self-esteem items and Factor II by four of the five Life Satisfaction items. Coefficient alpha was .77 for the Satisfaction With Life Scale and .97 for the Rosenberg Self-esteem Scale. Life Satisfaction was related to Self-esteem (r = .17, p Life Satisfaction and Self-esteem appear to be distinct, unitary constructs, but responses to Item 5 on the Satisfaction With Life Scale require cautious interpretation and may contribute to the weak r, although so may the collectivist culture of Black South Africans.

    Full Text Available A study was conducted with 487 black adult residents of a South African informal settlement (151 men and 336 women to ascertain satisfaction with personal and environmental quality of life. It was hypothesised that: (1 health status and life satisfaction were the underlying dimensions of personal quality of life (PQOL; (2 health status and life satisfaction were more strongly associated with PQOL than environmental quality of life (EQOL; and (3 life satisfaction and satisfaction with EQOL were positively related. Seventy per cent of respondents rated their health as good or better. Age, schooling and employment status were significantly related to health, life satisfaction and PQOL. Reliability (internal consistency coefficients were 0.77 for the 5-item life satisfaction scale and 0.82 for the 12-item EQOL measure. Factor analysis showed that safety and security was the major unmet service need. Health status and life satisfaction explained 38% of the variance in PQOL; health status explained only 4% of the variance in EQOL. Life satisfaction was significantly related to EQOL (r = 0.16, p = 0.01. The results provided support for all three hypotheses. It was concluded that the life satisfaction and EQOL measures had good reliability; there was a definite need for a safety and security programme; and good health was a more important predictor of PQOL than EQOL.

    Full Text Available Intimate partner violence (IPV against women slowly moved out of the private sphere and into the public realm in the United States in the early 1970’s. While progress has been made regarding psychological, physical, and sexual trauma related to IPV, it has been only in the last decade that attention about IPV has included an examination of the impact of economic abuse (EA. This is disturbing given that EA is one of the eight spokes on the Power and Control wheel (PCW and many women state that they are not able to leave or get away from the abusive relationship due to financial reasons. Using a multi-systems life course (MSLC perspective, this paper considers the importance of elevating EA as a form of IPV-related trauma. We examine EA’s differential impact among women, review current practices and policies, and conclude with implications for micro, mezzo, and macro levels of trauma-informed practice with survivors of EA.

  12. Integrating black liquor gasification with pulping - Process simulation, economics and potential benefits

    Science.gov (United States)

    Lindstrom, Erik Vilhelm Mathias

    Gasification of black liquor could drastically increase the flexibility and improve the profit potential of a mature industry. The completed work was focused on research around the economics and benefits of its implementation, utilizing laboratory pulping experiments and process simulation. The separation of sodium and sulfur achieved through gasification of recovered black liquor, can be utilized in processes like modified continuous cooking, split sulfidity and green liquor pretreatment pulping, and polysulfide-anthraquinone pulping, to improve pulp yield and properties. Laboratory pulping protocols have been developed for these modified pulping technologies and different process options evaluated. The process simulation work around BLG has led to the development of a WinGEMS module for the low temperature MTCI steam reforming process, and case studies comparing a simulated conventional kraft process to different process options built around the implementation of a BLG unit operation into the kraft recovery cycle. Pulp yield increases of 1-3% points with improved product quality, and the potential for capital and operating cost savings relative to the conventional kraft process have been demonstrated. Process simulation work has shown that the net variable operating cost for a pulping process using BLGCC is highly dependent on the cost of lime kiln fuel and the selling price of green power to the grid. Under the assumptions taken in the performed case study, the BLGCC process combined with split sulfidity or PSAQ pulping operations had net variable operating cost 2-4% greater than the kraft reference. The influence of the sales price of power to the grid is the most significant cost factor. If a sales price increase to 6 ¢/KWh for green power could be achieved, cost savings of about $40/ODtP could be realized in all investigated BLG processes. Other alternatives to improve the process economics around BLG would be to modify or eliminate the lime kiln unit

    Since black carbon concentrations are useful to reveal changes in anthropogenic activities, measurements taken from 2007 to 2015 in a Portuguese city are used to assess to which extent the ambient air was impacted by the economic crisis. The average black carbon concentrations are representative of an urban area of small size (1.3 ± 1.3 μg m -3 ). The highest concentrations are observed in the heating season, being biomass combustion one of the causes for the high values. The daily cycle of black carbon concentrations presents both morning and evening peaks, mainly due to road traffic and, in the heating season, to domestic heating as well. The yearly averaged black carbon mass concentrations decreased 33 % from 2007 to 2015, possibly due to a combination of the economic recession and environmental legislation. The reduction in road traffic led to a decrease in the daily morning peak from 2007 to 2015. This reduction was not followed by a decrease in the evening peak, explained by an increase in biomass burning. Biomass is the cheapest heating fuel in Portugal, and its consumption increased in the aftermath of the economic crisis. The use of bioenergy is an alternative to fossil fuels and presents many advantages. However, energy policies should discourage inefficient biomass burning and promote better ways of exploiting the available energy resources and emission air pollution mitigation strategies.

    Full Text Available The black economic empowerment (BEE score consists of seven elements, namely ownership,management control, employment equity, skills development, preferential procurement, enterprisedevelopment and socio-economic development. The purpose of this study is to establish whether anassociation exists between an entity’s BEE elements and its share returns in the short term.Based on prior literature, it appears that the market reacts positively to an announcement of a BEE deal,although the literature also indicates that an entity’s BEE score, which includes all seven elements of theBEE score, bears a negative relationship to its share returns. Therefore the association between the variousBEE elements and share returns needs to be investigated. The study uses a multivariate regressionanalysis that controls for factors influencing share returns. The study includes the BEE element data asobtained from the survey of the top empowerment companies carried out by Empowerdex/Financial Mail forthe period 2005 to 2011.The results of this study indicate that a significant positive association exists between the managementcontrol element of the BEE score and the entity’s share returns. Furthermore, a significant negativeassociation exists between the ownership and preferential procurement elements of an entity and its sharereturns. This study contributes to the literature on BEE in the accounting and finance field in South Africa aswell as enhances the understanding and effect of BEE compliance through implementation of the genericscorecard as required by the 2007 codes of good practice. The results of this study would be of interest togovernment policy analysts, investors and managers.

    Full Text Available Orientation: The key obstacle hindering optimal profitability levels and competitiveness in firms in South Africa is the application of labour legislation policies and tools aimed at narrowing the income gap between different racial groups and resolving inequality amongst a diverse workforce. Research purpose: This article determined whether the implementation of a Black Economic Empowerment (BEE policy by companies has a positive effect on their growth in terms of profits and competitiveness. Motivation for the study: This study determined whether the implementation of BEE could be profitable for companies. Research design, approach and method: A quantitative study was undertaken in order to find empirical evidence supporting the relation between high BEE Scores, profitability and competitiveness. The empirical investigation utilised regression analysis, correlations and other methods, based on data between January 2009 and December 2011. The BEE Scorecard was used to obtain BEE scores of the top 50 BEE companies. Thereafter, the top 50 companies’ financial information was gathered from the Johannesburg Securities Exchange. Main findings: The implementation of BEE within companies has a positive effect on profitability, turnover and investment. Numerous factors have, however, been hindering,while other factors enhanced the success of BEE. Practical/managerial implications: The findings encourage mangers to engage in BEE as it may facilitate higher profits and indicates where labour legislation could be improved. Contribution/value-add: Value was added through new research determining the effects of BEE and labour legislation on profitability and competitiveness of firms on a micro-level.

    2014-05-01

    Full Text Available Original Equipment Manufacturers (OEMs in South Africa are under pressure to meet the Black Economic Empowerment (BEE policies and charters of the South African government by giving BEE suppliers additional opportunities to tender. However, many BEE suppliers, due to being historically disadvantaged, experience various problems which make it difficult for them to win tenders, including lack of finances, opportunities to tender and management and business skills, and problems with quality and capacity. This paper outlines these practical problems experienced by BEE suppliers, the effects of these problems on risk and complexity in the South African automotive industry and policies that address these problems and assist BEE suppliers to become A-rated suppliers. Data for the paper was obtained from interviews with: senior employees of the AIDC involved with supplier development training; middle managers of supplier quality and development departments at the three OEMs in the Eastern Cape Province; and BEE and small suppliers identified to undergo AIDC training. The findings of the study are that unless sufficient training is given to BEE and potential BEE suppliers, supply to OEMs will remain in the hands of existing established suppliers and very little transformation will occur within the automobile industry in South Africa.

    This paper presents an economic model to explain the behavior of life expectancy of both sexes. It explicitly examines the relationship between the gender gap in life expectancy and the gender gap in pay. It shows that as the latter narrows over the course of economic development, the former may initially expand but will eventually shrink. Simulation results from our model accord with the behavior of life expectancy for both sexes since the 1940s in the United States.

  5. Life stage influences the resistance and resilience of black mangrove forests to winter climate extremes

    Osland, Michael J.; Day, Richard H.; From, Andrew S.; McCoy, Megan L.; McLeod, Jennie L.; Kelleway, Jeffrey

    2015-01-01

    In subtropical coastal wetlands on multiple continents, climate change-induced reductions in the frequency and intensity of freezing temperatures are expected to lead to the expansion of woody plants (i.e., mangrove forests) at the expense of tidal grasslands (i.e., salt marshes). Since some ecosystem goods and services would be affected by mangrove range expansion, there is a need to better understand mangrove sensitivity to freezing temperatures as well as the implications of changing winter climate extremes for mangrove-salt marsh interactions. In this study, we investigated the following questions: (1) how does plant life stage (i.e., ontogeny) influence the resistance and resilience of black mangrove (Avicennia germinans) forests to freezing temperatures; and (2) how might differential life stage responses to freeze events affect the rate of mangrove expansion and salt marsh displacement due to climate change? To address these questions, we quantified freeze damage and recovery for different life stages (seedling, short tree, and tall tree) following extreme winter air temperature events that occurred near the northern range limit of A. germinans in North America. We found that life stage affects black mangrove forest resistance and resilience to winter climate extremes in a nonlinear fashion. Resistance to winter climate extremes was high for tall A. germinans trees and seedlings, but lowest for short trees. Resilience was highest for tall A. germinans trees. These results suggest the presence of positive feedbacks and indicate that climate-change induced decreases in the frequency and intensity of extreme minimum air temperatures could lead to a nonlinear increase in mangrove forest resistance and resilience. This feedback could accelerate future mangrove expansion and salt marsh loss at rates beyond what would be predicted from climate change alone. In general terms, our study highlights the importance of accounting for differential life stage responses and

  6. Life cycle greenhouse gases and non-renewable energy benefits of kraft black liquor recovery

    2012-01-01

    The life cycle greenhouse gas (GHG) and fossil fuel benefits of black liquor recovery are analyzed. These benefits are due to the production of energy that can be used in the pulping process or sold, and the recovery of the pulping chemicals that would otherwise need to be produced from other resources. The fossil GHG emissions and non-renewable energy consumption of using black liquor in the kraft recovery system are approximately 90% lower than those for a comparable fossil fuel-based system. Across all scenarios, the systems relying on black liquor solids achieve a median reduction of approximately 140 kg CO 2 eq./GJ of energy produced, compared to the systems relying on fossil fuels to provide the same energy and pulping chemical production functions. The benefits attributable to the recovery of pulping chemicals vary from 44% to 75% of the total benefit. Applied to the total production of kraft pulp in the U.S., the avoided emissions are equivalent to the total Scopes 1 and 2 emissions from the entire U.S. forest products industry. These results do not depend on the accounting method for biogenic carbon (because biogenic CO 2 emissions are the same for the systems compared) and the results are valid across a range of assumptions about the displaced fossil fuel, the GHG-intensity of the electricity grid, the fossil fuels used in the lime kiln, and the level of cogeneration at pulp and paper mills. The benefits occur without affecting the amount of wood harvested or the amount of chemical pulp produced. -- Highlights: ► Black liquor, a by-product of kraft pulping, represents about half of the energy used in the paper industry. ► The greenhouse gases (GHG) benefits of black liquor recovery compared to an equivalent fossil fuel system were analyzed. ► The GHG emissions of the black liquor system are approximately 90% lower than those for the fossil fuel system. ► The benefits from the recovery of the chemicals vary from 44% to 75% of the total benefit.

  7. Chips in black boxes? Convenience life span, parafood, brandwidth, families, and co-creation.

    Jacobs, Marc

    2015-11-01

    Any consumer who opens a bag of potato or corn chips (or crisps in the UK) knows there is no time to waste to enjoy or share them. The convenience life span of chips is limited: it is the shelf or storage life and a very limited time once outside the bag. Many technologies converge to generate the desired effect as a black box, not only of the packaging but also of the chips themselves. The concept of paratext can be applied to printed messages on the package, including the brand name and other texts like advertising (epitexts), which can be expanded into the concept of parafood. These concepts help to discuss technological developments and interpret why this has recently become a negotiation zone for co-creation (see the Do us a flavor campaigns). They are symptoms of changing relations between production, research and development, marketing, and consumption. This paper pays special attention to back stories, underdog brand biographies and narratives about origin. The concept of brandwidth is introduced to sensitize about the limits of combining different stories about chips. A recent brand biography, a family history and a cookery book are used to discuss the phenomenon of cooking with Fritos. Together with the concepts of parafood, brandwidth and black boxes, more reflection and dialogue about the role of history and heritage in marketing put new challenging perspectives on the agenda.

    Full Text Available This paper explains the concepts of Affirmative Action (AA and Black Economic Empowerment (BEE and the policies developed in post-Apartheid South Africa. It compares it to similar policies adopted in different contexts in Malaysia, India and the U.S.A. It explains and critiques the South African policies on AA and BEE, its history since 1994 and how class has replaced race as the determinant of who succeeds in education and the workplace. It analyses why these policies were essential to address the massive racial divide in education and the workplace at the arrival of democracy in 1994, but also why it has been controversial and racially divisive. The strengths and limitations of these policies are juxtaposed, the way it has benefitted the black and white elites, bolstered the black middle-class but has had little success in addressing the education and job futures of poor, working class black citizens in South Africa. The views of a number of key social analysts in the field are stated to explain the moral, racial, divisive aspects of AA in relation to the international experience and how South Africa is grappling with limited success to bridge the divide between the rich and poor.

The public health survey in Scania in the southernmost part of Sweden in 2012 is a cross-sectional study based on a stratified random sample with 28,029 respondents aged 18–80 (51.7% response rate. Associations between childhood and adult economic stress, and low LTPA were analyzed with logistic regressions. A 14.8% prevalence of men and 13.5% of women had low LTPA (sedentary lifestyle. Low LTPA was associated with higher age, being born abroad, low socioeconomic status, low trust, smoking, poor self-rated health, and economic stress in childhood and adulthood. The odds ratios of low LTPA increased with more accumulated economic stress across the life course in a dose-response relationship. There was no specific critical period (childhood or adulthood, because economic stress in childhood and adulthood were both associated with low LTPA but the associations were attenuated after the introduction of smoking and self-rated health. The accumulation hypothesis was supported because the odds ratios of low LTPA indicated a graded response to life course economic stress. The critical period hypothesis was thus not supported. Economic stress across the life course seems to be associated with low LTPA in adulthood.

    2000-01-01

    The impracticability of Utopian schemes can be recognized by their failure to observe both the laws of thermodynamics, the second law in particular, and Gossen's laws. They are based on the assumption that there is such a thing as a free lunch or, in energy supply, a law on feeding electricity produced from wind energy and solar energy whose economic inefficiency must be paid for by others, i.e., on which energy is spent, and the entropy of the Earth systems is increased, at the expense of others. By their very economic inefficiency they provoke squandering of energy and resources and damage to the environment. This article explains the consequences resulting from the laws of thermodynamics with respect to global economic development. The availability of sufficient energy plays a key role in this respect. Compared to all possibilities of energy production known to date, nuclear power is able to supply energy, i.e. directed energy, as a production factor in unlimited quantities and without any detriment to the environment and, thanks to the creativity boost supplied by information technology, also to provide the large energy contributions required to solve worldwide problems.

    Manufacturers have been increasingly considering the implication of materials used in commercial products and the management of such products at the end of their useful lives (as waste or as post-consumer secondary materials). The present work describes the application of the life cycle thinking approach to a plastic product, specifically an anti-glare lamellae (used for road safety applications) made with high-density polyethylene (HDPE). This study shows that optimal environmental and economic outcomes associated with this product can be realized by recovering the material at the end of its useful life (end of life, EoL) and by using the recycled HDPE as a raw material in the production of new similar products. The study confirmed the applicability of the life cycle thinking approach by industry in sustainable products development, supporting the development of robust environmental and economic guidelines.

Much progress has been made in formally evaluating the degree of quality-of-life (QoL) impairment suffered by patients with urticaria. This review focuses on QoL in chronic urticaria (>6 weeks duration) and examines QoL measures, including the chronic urticaria-quality of life questionnaire (CU-Q2oL). Patients with urticaria have difficulty identifying and coping with their emotions. The psychiatric comorbidity and the financial burden on the patient and society because of chronic urticaria, is also examined.

    2018-02-13

    We articulate the lifespan theory of change by which an attachment-focused integrative reminiscence intervention, "Life Writing", is expected to interrupt the continuing problem of insecure attachment in adults and reverse associated reduced health and well-being outcomes. Based on preliminary studies and previous research, Life Writing is expected to foster earned-secure attachment in adults who work through subjective memories of unresolved attachment trauma. Roughly two decades of research on integrative reminiscence interventions like Life Writing show their consistent and wide-ranging positive impact. However, the bulk of this research demonstrates that such programs work, without also clarifying how they work, leaving unanswered questions as to how change occurs and how benefits might continue to accrue to participants through the lifespan. This represents what are known as "black box" effects. A program and evaluation planning tool, The Netway, was used to 1) identify hypothesized links between program inputs, activities, outputs, outcomes, and long-term impacts; 2) to clarify the underlying assumptions related to the program's success; and 3) to consider the appropriate contexts for the program. The logic model presented here articulates the hypothesized causal pathway from insecure to earned-secure attachment, in preparation for rigorous empirical tests of the program's lifespan theory of change.

    Attainment of 70 years life expectancy by 2020 is one of the millennium development goals in Nigeria. This study examined the socio-economic determinants of life expectancy in Nigeria using data from 1980-2011. Judging from the endogeneity feature of the variables, A VAR and VECM frameworks were employed. Socio-economic features were proxy by secondary school enrolment, government expenditure on health, per capita income, unemployment rate and the Naira foreign exchange rate. It was found that, the conventional socio-economic variables such as per capita income, education and government expenditure on health considered to be highly effective in determining life expectancy of developing countries are not significant in the case of Nigeria. The study however suggests that, life expectancy in Nigeria could be improved if attention is given to quality of government health expenditure, unemployment and measures to halt the depreciation of the Nigerian Naira against major foreign currency.

    2006-01-01

    In November 2003, the South African wine industry held its first consultative conference on ‘Black Empowerment’. The press reported to the world that the industry was at last entering ‘the new South Africa’. For years, it had been a byword for white power and black exploitation – famous for the grim working conditions, poor wages, degrading institutions, and authoritarian, racist white farmers. In contrast to the past, when talk of change was the prerogative of white and male industry insider...

  8. The trials, tribulations, and triumphs of black faculty in the math and science pipeline: A life history approach

    Science.gov (United States)

    Williams, Lisa D.

    2000-12-01

    This study explores the career progression and life history of black mathematicians and scientists who teach on university faculties in the United States. It investigates the following questions: Why are there so few black mathematicians and scientists in colleges and universities in the United States? What is the experience of black students who express an interest in science and math? What barriers do black scientists and mathematicians face as they move through school towards their career in higher education? What factors facilitate their success? The current literature shows that there are few women and minorities teaching or working in math and science compared to white men, although reasons for this underrepresentation are still not well understood. I explored this phenomenon by conducting two sets of in-depth interviews with twelve black faculty, six women, six men, from both historically black and predominantly white higher educational institutions in the United States. My interviews were based upon a life history approach that identified the participants' perceptions of the barriers and obstacles, as well as the supports and facilitators encountered in their schooling and career progression. The findings from the study show the importance of a strong family, community, and teacher support for the participants throughout their schooling. Support systems continued to be important in their faculty positions. These support systems include extended family members, teachers, community members, supervisors, and classmates, who serve as role models and mentors. The life study interviews provide striking evidence of the discrimination, isolation, and harassment due to race and gender experienced by black male and female mathematicians and scientists. The racial discrimination and the compounding effect of racism and sexism play out differently for the male and female participants in this study. This study suggests directions for future research on the experiences

    Atua, K.

    1999-01-01

    The reliability-based life approach is utilized. Selective failure modes of marine power plants are used for illustration. A case study of the Egyptian Commercial Fleet owned by the Public Sector Company was analyzed and used to establish a demonstration of the expected economic life based on local operating and maintenance conditions. The data acquired is analyzed and failure trend is derived for each failure mode. Probabilistic techniques are used to randomly generate numbers and times of occurrence of different failure modes. The reliability analysis is performed on the life span expected by the manufacture to predict the total number of failures, dependent failures, and cost of failures. Total expenditure due to random failure and cost of scheduled maintenance together with the annual income are utilized (using the time value of money) to determine the economic life of the plant. Conclusions are derived and recommendations for the enhancement of this work in the future are made

    2017-08-01

    Full Text Available In China, the oil and natural gas resources of Bohai Bay are mainly marginal oil fields. It is necessary to build both iceresistant and economical offshore platforms. However, there are many risks during the life cycle of offshore platforms due to the imperfect preliminary design for the Bohai Sea economical ice-resistant structures. As a result, the whole life-cycle design should be considered, including plan, design, construction, management and maintenance design. Based on the demand of existing codes and research of the basic design, structural ice-resistant performance and the reasonable management and maintenance, the life-cycle design theory is discussed. It was concluded that the life-cycle cost-effective optimum design proposed will lead to a minimum risk.

  12. A life cycle cost economics model for projects with uniformly varying operating costs. [management planning

    Remer, D. S.

    1977-01-01

    A mathematical model is developed for calculating the life cycle costs for a project where the operating costs increase or decrease in a linear manner with time. The life cycle cost is shown to be a function of the investment costs, initial operating costs, operating cost gradient, project life time, interest rate for capital and salvage value. The results show that the life cycle cost for a project can be grossly underestimated (or overestimated) if the operating costs increase (or decrease) uniformly over time rather than being constant as is often assumed in project economic evaluations. The following range of variables is examined: (1) project life from 2 to 30 years; (2) interest rate from 0 to 15 percent per year; and (3) operating cost gradient from 5 to 90 percent of the initial operating costs. A numerical example plus tables and graphs is given to help calculate project life cycle costs over a wide range of variables.

  13. Economic and quality-of-life outcomes in head and neck cancer

    International Nuclear Information System (INIS)

    Harrison, Louis B.

    1996-01-01

    Head and neck cancer offers a special and unique challenge to physicians and patients. Treatment of cancers in this part of the body, especially surgical resection, can cause profound changes in quality-of-life. The patient's ability to work, earn a living, articulate speech, communicate, have social interaction, and live a normal life, can be affected in a major way. Therefore, physicians and patients must look beyond the obvious oncologic outcomes of locoregional control, distant metastasis free survival, and overall survival. These outcomes must be assessed along with detailed, quality-of-life and economic outcomes, in order to properly manage patients. It is also mandatory that patients have a clear understanding of all their treatment options, and the implications of these options on cancer control and quality-of-life. This panel will focus on the available methods to assess quality-of-life and economic outcomes in head and neck cancer management. It will also highlight areas where new oncologic strategies are utilized which emphasize organ and function preservation. This latter area is an important aspect of modern clinical research and practice. In particular, management of cancers of the tongue, larynx, and hypopharynx offer special opportunities. Resection of these organs can produce debilitating functional outcomes. New multidisciplinary approaches to treat patients while avoiding primary resection have been developed. The oncologic and quality-of-life/economic outcomes will be assessed for these organ preserving strategies

    To estimate the association between socio-economic life course and body mass index (BMI), waist circumference (WC) and general and abdominal obesity in adults. A cross-sectional analysis of a population-based cohort study of 1,222 adults (aged 22-63) from Florianopolis, southern Brazil. The socio-economic life course was analysed using the educational level of participants and their parents. Height, weight and WC were measured by specially trained staff. Linear and logistic regressions were used with adjustment for confounding factors, and data were stratified according to sex. Mean BMI and WC were about 2kg/m 2 (95% CI: -3.3 to -0.7) and 6cm (95% CI: -9.7 to -2.9) lower in women with a high socio-economic position, while the association was reversed in men with a high socio-economic position, with WC being about 4cm higher (95% CI: 0.1 to 7.5). In addition, women who had always been in a high socio-economic position were less likely to have abdominal obesity (OR: 0.38; 95% CI: 0.20 to 0.76) while no such association was found in men. Socio-economic life course influences BMI, WC and obesity, with differences between males and females, thereby indicating that public policies that contemplate a socio-economic life course approach can be effective for controlling obesity.

    2010-08-01

    Research purpose: The objective of the study was to explore Black employees’ construction of work–life balance in a customer care environment. Motivation for the study: The conceptual debate regarding the construct of work–life balance in general as well as limited qualitative research with regard to Black employees’ experience of work–life balance in a South African context motivated the study. Research design, approach and method: This qualitative study was designed from an interpretivist perspective. Ten employees, selected through purposeful sampling, participated in the study. Data was gathered through in-depth interviews and grounded theory was applied during data analysis. Main findings: The grounded theory analysis of the data yielded six themes central to participants’ construction of work–life balance. The findings suggest that work–life balance is conceptualised as a continuous, subjective and holistic valuation of satisfaction derived from multiple roles in relation to the importance to the individual at a given point in time. Practical/managerial implications: Findings provide valuable managerial information to guide suitable strategies enhancing the work–life balance experience and by implication employees’ general wellbeing, job satisfaction and commitment. Contributions/value-add: This study contributes to the evolving body of knowledge with regard to work–life balance and provides a unique context-specific perspective to the conceptual understanding of the construct.

    2011-01-01

    The black water and grey water source-separation sanitation system aims at efficient use of energy (biogas), water and nutrients but currently lacks evidence of economic viability to be considered a credible alternative to the conventional system. This study intends to demonstrate economic viability, identify main cost contributors and assess critical influencing factors. A technico-economic model was built based on a new neighbourhood in a Canadian context. Three implementation scales of source-separation system are defined: 500, 5,000 and 50,000 inhabitants. The results show that the source-separation system is 33% to 118% more costly than the conventional system, with the larger cost differential obtained by lower source-separation system implementation scales. A sensitivity analysis demonstrates that vacuum toilet flow reduction from 1.0 to 0.25 L/flush decreases source-separation system cost between 23 and 27%. It also shows that high resource costs can be beneficial or unfavourable to the source-separation system depending on whether the vacuum toilet flow is low or normal. Therefore, the future of this configuration of the source-separation system lies mainly in vacuum toilet flow reduction or the introduction of new efficient effluent volume reduction processes (e.g. reverse osmosis).

    Full Text Available In our paper “Feraios Revised: Inter-Regional Trans-National Socioeconomic Cooperation in South and Eastern Europe”, published in International Relations and Diplomacy Journal (December 2014, we analyzed the prospects of an inter-regional cross-national cooperation (in economic, social and political patterns in South and Eastern Europe through the structural reorganization of the existing institutions (local, national or cross-national in the area and we expressed the need for the reintroduction of Rigas Feraios’ perspective of socioeconomic and ultimately of political integration in this region. The present paper is an attempt to explain the reasons why working on the regional socioeconomic cooperation and integration constitutes a necessary condition before going into a wider amalgamation. Contemporary systemic, global crisis brought out internal and transnational aberrations and the fact of the asymmetrical financial integration of the EU countries. The Union consists of a multilevel system were social conflicts, different rates of economic development and various demographic dynamics dominate. The increasing territorial inequalities in the enlarged Europe and the “suspended step” of a monetary unification might establish the need to revert to regional socioeconomic cooperation, on the basis of the existing cultural, economic and historical bonds, like those of South-East Europe and the Black Sea, for restarting European integration and succeed inter-union stability and prosperity.

    Sedinger, James S.; Flint, Paul L.; Lindberg, Mark S.

    1995-01-01

    We studied relationships between body size of female Black Brant goslings (Branta bernicla nigricans) late in their growth period and first year survival, eventual adult body size, breeding propensity, and size and volume of clutches they eventually produced to examine the relationship between growth and fitness in this population. We indexed body size by calculating PC1 scores based on either culmen and tarsus, or culmen, tarsus, and mass. Gosling (PC scores based on culmen and tarsus) size was positively correlated with resighting rate (P = 0.005), indicating that larger goslings survived at a higher rate than did smaller goslings. Gosling size was correlated with adult size of the same individuals (P = 0.0004). Larger goslings were more likely to breed as 2- or 3-yr-olds than were medium or small goslings (P = 0.008). Larger adult brant laid more eggs (P = 0.03) and produced clutches with greater total volume (P = 0.03) than did smaller brant. Given the important role of foraging environment in growth of goslings, these data suggest an important role of early environment in determining life-history traits.

  5. PLEXFIN a computer model for the economic assessment of nuclear power plant life extension. User's manual

    International Nuclear Information System (INIS)

    2007-01-01

    The IAEA developed PLEXFIN, a computer model analysis tool aimed to assist decision makers in the assessment of the economic viability of a nuclear power plant life/licence extension. This user's manual was produced to facilitate the application of the PLEXFIN computer model. It is widely accepted in the industry that the operational life of a nuclear power plant is not limited to a pre-determined number of years, sometimes established on non-technical grounds, but by the capability of the plant to comply with the nuclear safety and technical requirements in a cost effective manner. The decision to extend the license/life of a nuclear power plant involves a number of political, technical and economic issues. The economic viability is a cornerstone of the decision-making process. In a liberalized electricity market, the economics to justify a nuclear power plant life/license extension decision requires a more complex evaluation. This user's manual was elaborated in the framework of the IAEA's programmes on Continuous process improvement of NPP operating performance, and on Models for analysis and capacity building for sustainable energy development, with the support of four consultants meetings

    Full Text Available The wine sector is going through a significant evolution dealing with the challenges of competition issues in international markets and with necessary commitments to sustainability improvement. In the wine supply chain, the agricultural phase represents a potential source of pollution and costs. From the farmers’ point of view, these contexts require them to be more attentive and find a compromise among environmental benefits, economic benefits, and costs linked to farming practices. This paper aims to make a sustainability assessment of different wine-growing scenarios located in Calabria (Southern Italy that combines conflicting insights, i.e., environmental and economic ones, by applying Life Cycle Assessment (LCA and Life Cycle Costing (LCC to identify the main hotspots and select the alternative scenarios closest to the ideal solution through the VIKOR multicriteria method. In particular, the latter allowed us to obtain synthetic indices for a two-dimensional sustainability assessment. Conventional practices associated to the espalier training system represent the best compromise from both environmental and economic points of view, due to the higher yield per hectare. The choices regarding Functional Unit (FU and indicators were shown to have a high influence on results.

  8. Effects of sex control and twinning on economic optimization of culling cows in Japanese Black cow-calf production systems.

    2012-01-15

    The effects of sex control and twinning techniques on determination of optimal culling parity of cows in beef cow-calf production systems were deterministically analyzed using a herd model simulation. The model simulated the annualized net revenue as an economic indicator during the whole life cycle of a cow. Biological factors (survivability, growth, reproduction, and feed requirements) and economic factors (returns from sales of live calves and cows' carcasses and production costs) were included in the model. Some biological and economic parameters relating to these factors were altered from a base condition in order to adapt the production systems with sex control and twinning techniques. Based on the model, early culling was optimal for all production systems when biological efficiency was used as an indicator of production; however, later culling was optimal for single production, but slightly earlier culling was optimal for twin production, when annualized net revenue was evaluated. The introduction of sex control did not greatly affect the determination of the optimal culling parity of cows. When production included the sex control, female sexing increased biological efficiency, whereas male sexing increased annualized net revenue. In the present beef cow-calf production circumstances in Japan, introduction of sex control did not have economically appreciable effects, but twinning was economically beneficial. For production involving sex control, improvement in the conception rate per mating and/or reduction of technical cost were required for this technology to be profitable.

    To investigate associations between economic stress in childhood and adulthood, and lack of internal health locus of control (HLC), testing the accumulation and critical period life course hypotheses. A cross-sectional public health (postal) survey was conducted in Skåne in 2008, based on a random sample with 28,198 participants in the age interval 18-80 years, with 55% participation. Logistic regressions analyzed associations between childhood and current economic stress, and lack of internal HLC. A 33.7% prevalence of men and 31.8% of women lack internal HLC, which was significantly associated with the covariates included. The accumulation hypothesis was partly supported because combined childhood and adulthood economic stress exposures were significantly associated with lack of internal HLC in a graded manner. The critical period hypothesis was not supported since the association between economic stress in childhood and lack of internal HLC was partly significant in the final model, and the association with adult (current) economic stress was also significant. The accumulation hypothesis was partly supported. The critical period hypothesis was not supported since both childhood and current economic stress experience were significantly associated with lack of internal HLC. Economic conditions in childhood as well as adulthood are plausibly of relevance for HLC.

    Full Text Available It is of importance to include the appropriate costs and outcomes when evaluating a health intervention. Sweden is the only country where the national guidelines of decisions on reimbursement explicitly state that costs of added life years should be accounted for when presenting health economic evaluations. The aim of this article is to, from a theoretical and empirical point of view, critically analyze the Swedish recommendations used by the Dental and Pharmaceutical Benefits Agency (TLV, when it comes to the use of costs of added life years in economic evaluations of health care. The aim is furthermore to analyze the numbers used in Sweden and discuss their impact on the incremental cost‑effectiveness ratios of assessed technologies. If following a societal perspective, based on welfare economics, there is strong support for the inclusion of costs of added life years in health economic evaluations. These costs have a large impact on the results. However this fact may be in conflict with ethical concerns of allocation of health care resources, such as favoring the younger part of the population over the older. It is important that the estimates of production and consumption reflect the true societal values, which is not the case with the values used in Sweden.http://dx.doi.org/10.7175/fe.v15i2.925

    Full Text Available Black soldier fly (BSF larvae, Hermetia illucens L., develops on organic wastes, reducing ecological pollution and converting waste biomass into protein and fat rich insect biomass. BSF can replace increasingly expensive protein sources used in poultry, aquaculture and livestock compound diet formulation, such as fish meal and soybean meal, which holds the potential to alleviate future food and feed insecurity. The fate of nutritional spectra in BSF during its life cycle phases is still poorly understood. This study assessed metabolic changes in nutrition composition of BSF from egg to adult. A rapid increase of crude fat content was observed since the development of 4-14 days of larvae with its maximum level reaching 28.4% in dry mass, whereas the crude protein displayed a continuous decreasing trend in the same development phases with minimum level of 38% at larval phase (12 days and peak level of 46.2% at early pupa stage. A sharp drop in crude fat was noticed from early prepupae to late pupae (24.2%, 8.2% respectively. However crude protein shows its maximum value being 57.6% at postmortem adult stage with 21.6% fat level. In addition, fatty acids, amino acids, minerals and vitamins composition in different development stages of BSF were presented and compared. Findings from this study could provide podium to food and feed industry for framing a strategy for specific molecular nutritional component intake into the diets of humans, aquaculture and animals. It is also indicated that BSF is a possible insect which can be applied to combating the food scarcity of countries where micronutrient deficiency is prevalent. Moreover it contributes to advance exploring for developmental and metabolic biology of this edible insect.

    Measuring health-related quality of life is an important aspect in economic evaluation of health programmes. The development of utility-based (preference-based) measures is advanced by the discipline of health economics. Different preference measures are applied for valuing health states to produce a weighted health state index. Those preference weights should be derived from a general population sample in case of resource allocation on a collective level (as in current valuation studies of the EuroQol group).

    Full Text Available Orientation: Work–life balance, as a crucial aspect of employee and organisational wellness, remains an interesting field of research, especially due to the changing demographic employee profile.Research purpose: The objective of the study was to explore Black employees’ construction of work–life balance in a customer care environment.Motivation for the study: The conceptual debate regarding the construct of work–life balance in general as well as limited qualitative research with regard to Black employees’ experience of work–life balance in a South African context motivated the study.Research design, approach and method: This qualitative study was designed from an interpretivist perspective. Ten employees, selected through purposeful sampling, participated in the study. Data was gathered through in-depth interviews and grounded theory was applied during data analysis.Main findings: The grounded theory analysis of the data yielded six themes central to participants’ construction of work–life balance. The findings suggest that work–life balance is conceptualised as a continuous, subjective and holistic valuation of satisfaction derived from multiple roles in relation to the importance to the individual at a given point in time.Practical/managerial implications: Findings provide valuable managerial information to guide suitable strategies enhancing the work–life balance experience and by implication employees’ general wellbeing, job satisfaction and commitment.Contributions/value-add: This study contributes to the evolving body of knowledge with regard to work–life balance and provides a unique context-specific perspective to the conceptual understanding of the construct.

    Full Text Available Wheelchairs for children with impaired mobility provide health, developmental and psychosocial benefits, however there is limited understanding of how mobility aids affect the health-related quality of life of children with impaired mobility. Preference-based health-related quality of life outcome measures are used to calculate quality-adjusted life years; an important concept in health economics. The aim of this research was to understand how young wheelchair users and their parents define health-related quality of life in relation to mobility impairment and wheelchair use.The sampling frame was children with impaired mobility (≤18 years who use a wheelchair and their parents. Data were collected through semi-structured face-to-face interviews conducted in participants' homes. Qualitative framework analysis was used to analyse the interview transcripts. An a priori thematic coding framework was developed. Emerging codes were grouped into categories, and refined into analytical themes. The data were used to build an understanding of how children with impaired mobility define health-related quality of life in relation to mobility impairment, and to assess the applicability of two standard measures of health-related quality of life.Eleven children with impaired mobility and 24 parents were interviewed across 27 interviews. Participants defined mobility-related quality of life through three distinct but interrelated concepts: 1 participation and positive experiences; 2 self-worth and feeling fulfilled; 3 health and functioning. A good degree of consensus was found between child and parent responses, although there was some evidence to suggest a shift in perception of mobility-related quality of life with child age.Young wheelchair users define health-related quality of life in a distinct way as a result of their mobility impairment and adaptation use. Generic, preference-based measures of health-related quality of life lack sensitivity in this

    van den Berg, Gerard J; Gupta, Sumedha

    2015-03-01

    This paper analyzes the interplay between early-life conditions and marital status, as determinants of adult mortality. We use individual data from Dutch registers (years 1815-2000), combined with business cycle conditions in childhood as indicators of early-life conditions. The empirical analysis estimates bivariate duration models of marriage and mortality, allowing for unobserved heterogeneity. Results show that conditions around birth and school going ages are important for marriage and mortality. Men typically enjoy a protective effect of marriage, whereas women suffer during childbearing ages. However, having been born under favorable economic conditions reduces female mortality during childbearing ages. Copyright © 2014 Elsevier B.V. All rights reserved.

  19. Union formation in later life: economic determinants of cohabitation and remarriage among older adults.

    Vespa, Jonathan

    2012-08-01

    This study builds on Becker's and Oppenheimer's theories of union formation to examine the economic determinants of marriage and cohabitation during older adulthood. Based on the 1998-2006 Health and Retirement Study and a sample of previously married Americans who are at least 50 years old, results show that wealthier older adults, regardless of gender, are more likely to repartner than stay single. Wealth has no discernable effect on the likelihood of remarrying versus cohabiting. Among the oldest men, the positive associations between wealth and repartnering are entirely due to housing assets. Results suggest that Oppenheimer's theory of marriage timing may be more applicable to later-life union formation than Becker's independence hypothesis. Further, economic disadvantage does not appear to characterize later-life cohabitation, unlike cohabitation during young adulthood. These findings help illuminate the union formation process during older adulthood and are timely considering demographic changes reshaping the American population.

    Full Text Available In this study, the relationship between life expectancy of men and women in Turkey and socio-economic variables are examined. The effect of demographic and economic factors such as the ratio of health expenditures to GDP, the ratio of elderly to employable population, the number of hospital beds per thousand people, the number of doctors per thousand patients are analyzed for a period of 1975-2009. In this study, the unit root test is initialy applied to each data set and then the cointegration test results is interpreted to determine whether a meaningful relationship exists between indicators in the long-term. Finally, the effects of the underlying factors on men and women were examined by vector error correction model. These results support that each factor has a significant effect on the life expectancy of men and women in Turkey.

    2014-09-01

    Full Text Available Farm machinery managers often need to make complex economic decisions on machinery replacement. Repair and maintenance costs can have significant impacts on this economic decision. The farm manager must be able to predict farm machinery repair and maintenance costs. This study aimed to identify a regression model that can adequately represent the repair and maintenance costs in terms of machine age in cumulative hours of use. The regression model has the ability to predict the repair and maintenance costs for longer time periods. Therefore, it can be used for the estimation of the economic life. The study was conducted using field data collected from 11 John-Deer 955 combine harvesters used in several western provinces of Iran. It was found that power model has a better performance for the prediction of combine repair and maintenance costs. The results showed that the optimum replacement age of John-Deer 955 combine was 54300 cumulative hours.

  3. Leading Causes of Death Contributing to Decrease in Life Expectancy Gap Between Black and White Populations: United States, 1999-2013.

    Life expectancy at birth has increased steadily since 1900 to a record 78.8 years in 2013. But differences in life expectancy between the white and black populations still exist, despite a decrease in the life expectancy gap from 5.9 years in 1999 to 3.6 years in 2013. Differences in the change over time in the leading causes of death for the black and white populations have contributed to this decrease in the gap in life expectancy. Between 1999 and 2013, the decrease in the life expectancy gap between the black and white populations was mostly due to greater decreases in mortality from heart disease, cancer, HIV disease, unintentional injuries, and perinatal conditions among the black population. Similarly, the decrease in the gap between black and white male life expectancy was due to greater decreases in death rates for HIV disease, cancer, unintentional injuries, heart disease, and perinatal conditions in black males. For black females, greater decreases in diabetes death rates, combined with decreased rates for heart disease and HIV disease, were the major causes contributing to the decrease in the life expectancy gap with white females. The decrease in the gap in life expectancy between the white and black populations would have been larger than 3.6 years if not for increases in death rates for the black population for aortic aneurysm, Alzheimer’s disease, and maternal conditions. For black males, the causes that showed increases in death rates over white males were hypertension, aortic aneurysm, diabetes, Alzheimer’s disease, and kidney disease, while the causes that showed increases in death rates for black females were Alzheimer’s disease, maternal conditions, and atherosclerosis. This NCHS Data Brief is the second in a series of data briefs that explore the causes of death contributing to differences in life expectancy between detailed ethnic and racial populations in the United States. The first data brief focused on the racial differences in life

    Investigations of mental health in a life course perspective are scarce. The aim is to investigate associations between economic stress in childhood and adulthood, and poor psychological health in adulthood with reference to the accumulation, critical period and social mobility hypotheses in life course epidemiology. The 2008 public health survey in Skåne is a cross-sectional postal questionnaire study. A random sample was invited which yielded 28,198 respondents aged 18-80 (55% participation). Psychological health was assessed with the GHQ12 instrument. Logistic regression models were used to investigate the associations adjusting for age, country of birth, socioeconomic status, emotional support, instrumental support and trust, and stratifying by sex. The accumulation hypothesis was confirmed because combined childhood and adulthood exposures to economic stress were associated with poor psychological health in a graded manner. The social mobility hypothesis was also confirmed. The critical period hypothesis was not confirmed because both childhood and adulthood economic stress remained significantly associated with poor psychological health in adulthood. Economic stress in childhood is associated with mental health in adulthood. © 2013 Published by Elsevier Ireland Ltd.

    Due to limited end-of-life discussions and the absence of palliative care, hospitalisations are frequent at the end of life among nursing home residents in Singapore, resulting in high health-care costs. Our objective was to evaluate the economic impact of Project Care at the End-of-Life for Residents in homes for the Elderly (CARE) programme on nursing home residents compared to usual end-of-life care. DESIGN AND SETTINGS/PARTICIPANTS: Project CARE was introduced in seven nursing homes to provide advance care planning and palliative care for residents identified to be at risk of dying within 1 year. The cases consisted of nursing home residents enrolled in the Project CARE programme for at least 3 months. A historical group of nursing home residents not in any end-of-life care programme was chosen as the matched controls. Cost differences between the two groups were analysed over the last 3 months and final month of life. The final sample comprised 48 Project CARE cases and 197 controls. Compared to the controls, the cases were older with more comorbidities and higher nursing needs. After risk adjustment, Project CARE cases demonstrated per-resident cost savings of SGD$7129 (confidence interval: SGD$4544-SGD$9714) over the last 3 months of life and SGD$3703 (confidence interval: SGD$1848-SGD$5557) over the last month of life (US$1 = SGD$1.3). This study demonstrated substantial savings associated with an end-of-life programme. With a significant proportion of the population in Singapore requiring nursing home care in the near future, these results could assist policymakers and health-care providers in decision-making on allocation of health-care resources.

    This paper presents a second part reporting on Community Disability Entrepreneurship Project (CoDEP) which was initiated in order to contribute to the development of entrepreneurial skills of disabled people living in informal settlements around Cape Town, South Africa. The aim of CoDEP has been the upliftment and economic empowerment of disabled people. This paper describes the point of departure, the theoretical framework of participatory action research (PAR), the development of research parameters, and continued focus. A participatory action research (PAR) approach was initiated in order to monitor and inform the effective development of CoDEP. This cyclic methodology allowed all participants to engage in decision-making and development of the programme. While negotiating partnerships with disabled entrepreneurs, the six spheres within which optimal interaction could take place emerged as: (i) the choice of occupation; (ii) changing a culture of receiving; (iii) nurturing teamwork by negotiating roles and responsibilities; (iv) a focus on ability; (v) understanding the research process; and (vi) organizational development dynamics. Committed interaction emerged as the quintessence of these partnerships.

  7. Economic Value Added as a Dependence on the Corporate- and Market-life Cycle

    Full Text Available Economic value added (EVA is an indicator which is widely used as the main tool for financial analysis. There are two methods of calculating it. The original method which was made by Stern & Stewart is defined as the net operating profit after taxes minus the cost of capital. The second method which was developed and used by the “Czech Ministry of Industry and Trade” indicates that, the economic value added is the difference between return on equity and the alternate cost of equity that is composed of separate risk rewards, and this “spread” is consequently multiplied by the equity. Economic value added depends on many factors. Whereas some of them are controllable by the company, others are not. This article is focused on the relationship between economic value added and the corporate- vs. market life cycle. This is because, there is an assumption that conditions for developing EVA changes depending on the actual phase of corporate- and market life cycle. In this research, the model by Reiners (2004 is used to identify the phases of corporate- and market life cycle and the method provided by the “Czech Ministry of Industry and Trade” is used to calculate EVA. However, there is a consideration of the relativity of EVA in the form of “spread” because of the intercompany comparison. The study found that, the highest spread is achieved by companies that are in the phase of expansion and phase of market expansion. On the contrary, companies in the phase of declension during market declension achieved the lowest and negative spread.

    This is an empirical study on the underrepresentation of people of color in scientific careers. Grounded in critical race theory, the paper examines the lived experiences of six Black women physicists and addresses obstacles faced in their career paths and strategies used to overcome these obstacles. Data for this study were collected through semi-structured interviews and coded for emergent themes. The findings reveal that college recruitment and funding were fundamental for these women to choose physics over other STEM fields. In addition, Black women experience unique challenges of socialization in STEM, particularly by exclusion of study groups. We suggest physics departments provide a more inclusive environment to support Black women in science.

    Economic analysis of life-saving investments in both the public and private sectors has the potential to dramatically improve longevity and the quality of life, but only if the analyses on which decisions are based are done well. In this article, we analyze a data set that provides information on the content and quality of journal articles that measure the cost-effectiveness of life-saving investments. Our study is the first to provide a detailed multivariate analysis of factors affecting objective measures of quality. We also explore whether a series of recommendations by an expert panel convened by the U.S. Public Health Service affect the way analyses of specific life-saving investments are done. Our results suggest that four factors are positively correlated with an index we construct to measure analytical quality: (1) having at least one author affiliated with a university, (2) publication in a journal that has experience in publishing these analyses, (3) if the life-saving investment is located in the United States, and (4) if the analysis considers a measure of social costs or benefits. Somewhat surprisingly, a study's funding source and whether it is affiliated with industry are not significantly correlated with the quality index. Finally, neither time nor the panel guidelines had an impact on the index.

    Reduced quality of life (QoL) is a known consequence of chronic disease in children, and this association may be more evident in those who are socio-economically disadvantaged. The aims of this systematic review were to assess the association between socio-economic disadvantage and QoL among children with chronic disease, and to identify the specific socio-economic factors that are most influential. MEDLINE, Embase and PsycINFO were searched to March 2015. Observational studies that reported the association between at least one measure of social disadvantage in caregivers and at least one QoL measure in children and young people (age 2-21 years) with a debilitating non-communicable childhood disease (asthma, chronic kidney disease, type 1 diabetes mellitus and epilepsy) were eligible. A total of 30 studies involving 6957 patients were included (asthma (six studies, n = 576), chronic kidney disease (four studies, n = 796), epilepsy (14 studies, n = 2121), type 1 diabetes mellitus (six studies, n = 3464)). A total of 22 (73%) studies reported a statistically significant association between at least one socio-economic determinant and QoL. Parental education, occupation, marital status, income and health insurance coverage were associated with reduced QoL in children with chronic disease. The quality of the included studies varied widely and there was a high risk of reporting bias. Children with chronic disease from lower socio-economic backgrounds experience reduced QoL compared with their wealthier counterparts. Initiatives to improve access to and usage of medical and psychological services by children and their families who are socio-economically disadvantaged may help to mitigate the disparities and improve outcomes in children with chronic illnesses. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    The environmental outcomes of urban form changes should couple life-cycle and behavioral assessment methods to better understand urban sustainability policy outcomes. Using Phoenix, Arizona light rail as a case study, an integrated transportation and land use life-cycle assessment (ITLU-LCA) framework is developed to assess the changes to energy consumption and air emissions from transit-oriented neighborhood designs. Residential travel, commercial travel, and building energy use are included and the framework integrates household behavior change assessment to explore the environmental and economic outcomes of policies that affect infrastructure. The results show that upfront environmental and economic investments are needed (through more energy-intense building materials for high-density structures) to produce long run benefits in reduced building energy use and automobile travel. The annualized life-cycle benefits of transit-oriented developments in Phoenix can range from 1.7 to 230 Gg CO2e depending on the aggressiveness of residential density. Midpoint impact stressors for respiratory effects and photochemical smog formation are also assessed and can be reduced by 1.2-170 Mg PM10e and 41-5200 Mg O3e annually. These benefits will come at an additional construction cost of up to $410 million resulting in a cost of avoided CO2e at $16-29 and household cost savings.

    Late-life depression encompasses both patients with late-life onset of depression (>60 years) and older adults with a prior and current history of depression. The aim of the study was to analyze the impact of the economic condition and family relations in childhood as risk factors for late-life depression. This was an analytical cross-sectional study comprising 120 subjects, 60 patients with unipolar depression and 60 subjects without depressive disorders, diagnosed in accordance with the 10-th International Classification of Mental and Behavioural Disorders. All participants in the study were above the age of 60 and there was no significant statistical difference in the sex proportion in both groups (p>0.05). Data for the examination were taken from a self-reported questionnaire designed for our aim. The Geriatric Depression Scale was used to measure depressive symptoms. Our results have shown that severe financial difficulties are important events in childhood and are risk factors for depression in the elderly (Chi-square=12.68, df=2, p=0.0018). Our investigation has found the association of family relations with late-life depression. In fact, conflictual relations in the family were more common in the experimental group than in the control group (Chi-square=14.32, df=3, p=0.0025). Furthermore, father's addiction to alcohol in childhood was associated with depression in later life (p=0.013). The difference in childhood emotional neglect and unequal treatment between siblings in both groups was insufficient to be confirmed statistically, but the examinees with this trauma had a threefold higher chance of having depression later in life (Odds ratio=3.04, 95% CL0.92 family conflicts during childhood are associated with late-life depression. Father's addiction to alcohol and parents' negative personal character traits are associated with depression in the elderly.

    To describe the profile of a sample of octogenarians (n=80) attended at the municipal health network of a city in the interior of São Paulo, Brazil; evaluate their perception regarding quality of life dimensions (QoL); identify correlations between socio economic status, education level and QoL. It is an exploratory descriptive study with a quantitative analysis of data. The results revealed that this population is predominantly female, widowed, illiterate, sedentary and poor, who need health services and leisure opportunities, and whose main support is religion. The socio economic status did not interfere in the QoL perception, though, higher education and participation in physical activities result in higher satisfaction.

    2016-12-01

    Cities throughout the U.S. are seeking efficient ways to manage stormwater for many reasons, including flood control, pollution management, water supply augmentation and to prepare for a changing climate. Traditionally, cities have relied primarily on gray infrastructure, namely sewers, storage and treatment facilities. In these systems, urban runoff, its volume increasing as impervious surfaces expand, is channeled to a wastewater plant where it is mixed with raw sewage prior to treatment or it is discharged, generally untreated, to local water bodies. These facilities are inflexible and expensive to build and maintain. Many systems are deteriorating and/or approaching, if not exceeding, their design capacity. Increasingly, more innovative approaches that integrate stormwater management into the natural environment and that make sense at both local and regional scales are sought. Identifying the best stormwater solution will require evaluating the life-cycle economic costs associated with these alternatives, including costs associated with construction, operation, and maintenance including regulatory and permitting costs, financing, as well as other indirect costs (e.g., avoided wastewater processing or system capacity expansion, increased property value) and non-economic co-benefits (i.e, aesthetics, habitat provision). Beyond conventional life-cycle costing, applying life-cycle assessment (LCA) will contribute to more holistic and sustainable decision-making. LCA can be used to quantitatively track energy use, greenhouse gas emissions, and other environmental effects associated with constructing, operating, and maintaining green and gray infrastructure, including supply chain contributions. We will present the current state of knowledge for implementing life-cycle costing and LCA into stormwater management decisions for green, gray and hybrid infrastructure.

    Full Text Available In recent years, there has been an increasing interest in Life Cycle Assessment (LCA applied to estimate the cradle-to-grave environmental impact of agricultural products or processes. Furthermore, including in the analysis an economic evaluation, from the perspective of an integrated life cycle approach, appears nowadays as a fundamental improvement. In particular, Life Cycle Costing (LCC, is a method that could integrate financial data and cost information with metrics of life cycle approaches. In this study, LCA in conjunction with LCC methods were used, with the aim to evaluate the main cost drivers—environmental and economic—of five widely diffused and market-valued agricultural productions (organic tomato and pear, integrated wheat, apple and chicory and to combine the results in order to understand the long-term externalities impacts of agricultural productions. Data obtained in local assessment show a wide margin of improvement of resources management at farms level in the short-term, but also allow for the investigation of future effects of environmental impacts not expressed in product price on the market. Reaching a real sustainable model for agriculture could be a value added approach firstly for farmers, but also for all the people who live in rural areas or use agricultural products.

    This talk presents an empirical study on the underrepresentation of people of color in scientific careers. Grounded in Critical Race Theory, the presentation examines the lived experiences of six Black women physicists in the United States, addresses obstacles faced in their career paths, and strategies used to overcome these obstacles. Data for this study were collected through semi-structured interviews and coded for emergent themes, which are invitation to engage in science, communities of science practices, and isolation in the academy. The findings reveal that college recruitment and funding were fundamental for these women to choose Physics over other STEM fields. The analysis shows Physics can be a hostile environment for these women. In addition, Black women experience unique challenges of socialization in Physics, particularly by exclusion of study groups. In this talk, suggestions will be presented to make Physics departments a more inclusive space to support Black women in science. This presentation is based on work supported by the Brazilian government through CAPES (BEX1907-07-7), the Fulbright Program, Comissño Fulbright Brasil, and the Office of Diversity at Teachers College, Columbia University.

    This study uses a life cycle costing (LCC) methodology to identify when hydrogen can become economically feasible compared to the conventional fuels and which energy policy is the most effective at fostering the penetration of hydrogen in the competitive fuel market. The target hydrogen pathways in this study are H 2 via natural gas steam reforming (NG SR), H 2 via naphtha steam reforming (Naphtha SR), H 2 via liquefied petroleum gas steam reforming (LPG SR), and H 2 via water electrolysis (WE). In addition, the conventional fuels (gasoline, diesel) are also included for the comparison with the H 2 pathways. The life cycle costs of the target fuels are computed and several key factors are examined to identify the economical feasibilities of the target systems: fuel cell vehicle (FCV) price, social cost of greenhouse gases (GHGs) and regulated air emissions (CO, VOC, SO x , NO x , PM), fuel efficiency of FCV, capital costs of H 2 equipments at a H 2 fueling station. The life cycle costs of a H 2 pathway also depend on the production capacity. Although, at present, all H 2 pathways are more cost efficient than the conventional fuels in the fuel utilization stage, the H 2 pathways have lack competitiveness against the conventional fuels in the life cycle (well to wheel) costs due to the high price of FCV. From future scenario analyses in 2015, all H 2 pathways are expected to have lower life cycle costs than the conventional fuels as a transportation fuel. It is evident that the FCV price is the most important factor for encouraging the hydrogen economy and FCVs. Unless the FCV price is below US $62,320, it is necessary for the institution to subsidize the FCV price by any amount over US $62,320 in order to inject H 2 into the market of transportation fuel. The incentive or taxes on GHGs and regulated air emissions are also expected to effectively encourage the diffusion of H 2 and FCV, especially for the H 2 pathway of WE with wind power (WE[Wind]). The uncertainties

    Life cycle assessment for sewage sludge treatment was carried out by estimating the environmental and economic impacts of the six alternative scenarios most often used in Japan: dewatering, composting, drying, incineration, incinerated ash melting and dewatered sludge melting, each with or without digestion. Three end-of-life treatments were also studied: landfilling, agricultural application and building material application. The results demonstrate that sewage sludge digestion can reduce the environmental load and cost through reduced dry matter volume. The global warming potential (GWP) generated from incineration and melting processes can be significantly reduced through the reuse of waste heat for electricity and/or heat generation. Equipment production in scenarios except dewatering has an important effect on GWP, whereas the contribution of construction is negligible. In addition, the results show that the dewatering scenario has the highest impact on land use and cost, the drying scenario has the highest impact on GWP and acidification, and the incinerated ash melting scenario has the highest impact on human toxicity due to re-emissions of heavy metals from incinerated ash in the melting unit process. On the contrary, the dewatering, composting and incineration scenarios generate the lowest impact on human toxicity, land use and acidification, respectively, and the incinerated ash melting scenario has the lowest impact on GWP and cost. Heavy metals released from atmospheric effluents generated the highest human toxicity impact, with the effect of dioxin emissions being significantly lower. This study proved that the dewatered sludge melting scenario is an environmentally optimal and economically affordable method.

    Search engine query data deliver insight into the behaviour of individuals who are the smallest possible scale of our economic life. Individuals are submitting several hundred million search engine queries around the world each day. We study weekly search volume data for various search terms from 2004 to 2010 that are offered by the search engine Google for scientific use, providing information about our economic life on an aggregated collective level. We ask the question whether there is a link between search volume data and financial market fluctuations on a weekly time scale. Both collective 'swarm intelligence' of Internet users and the group of financial market participants can be regarded as a complex system of many interacting subunits that react quickly to external changes. We find clear evidence that weekly transaction volumes of S&P 500 companies are correlated with weekly search volume of corresponding company names. Furthermore, we apply a recently introduced method for quantifying complex correlations in time series with which we find a clear tendency that search volume time series and transaction volume time series show recurring patterns.

    Highlights: • Integrated assessment of solar thermal enhanced oil recovery (TEOR). • Analyses of reservoir performance, economics, and life cycle factors. • High solar fraction scenarios show economic viability for TEOR. • Continuous variable-rate steam injection meets the benchmarks set by conventional steam flood. - Abstract: The viability of solar thermal steam generation for thermal enhanced oil recovery (TEOR) in heavy-oil sands was evaluated using San Joaquin Valley, CA data. The effectiveness of solar TEOR was quantified through reservoir simulation, economic analysis, and life-cycle assessment. Reservoir simulations with continuous but variable rate steam injection were compared with a base-case Tulare Sand steamflood project. For equivalent average injection rates, comparable breakthrough times and recovery factors of 65% of the original oil in place were predicted, in agreement with simulations in the literature. Daily cyclic fluctuations in steam injection rate do not greatly impact recovery. Oil production rates do, however, show seasonal variation. Economic viability was established using historical prices and injection/production volumes from the Kern River oil field. For comparison, this model assumes that present day steam generation technologies were implemented at TEOR startup in 1980. All natural gas cogeneration and 100% solar fraction scenarios had the largest and nearly equal net present values (NPV) of $12.54 B and $12.55 B, respectively. Solar fraction refers to the steam provided by solar steam generation. Given its large capital cost, the 100% solar case shows the greatest sensitivity to discount rate and no sensitivity to natural gas price. Because there are very little emissions associated with day-to-day operations from the solar thermal system, life-cycle emissions are significantly lower than conventional systems even when the embodied energy of the structure is considered. We estimate that less than 1 g of CO 2 /MJ of refined

    We assessed whether economic, legal, and social hardships were associated with human immunodeficiency virus (HIV) risk among a sample of Black men who have sex with men (MSM) and whether associations were moderated by city of residence. The study analyzed baseline and follow-up data from HIV Prevention Trials Network 061 (N = 1553). Binary logistic regression assessed associations between hardships and HIV risk indicators. Multivariate regressions were used to test if city of residence had a moderating effect for hardships and HIV risks. Adjusted analyses showed that Black MSM with recent job loss were more likely to engage in condomless insertive anal intercourse (adjusted odds ratios (AOR) = 1.37, 95% CI 1.01-1.87) and that those with recent financial crisis were more likely to have had two or more male sexual partners in the past 6 months (AOR = 1.65; 95% CI 1.18-2.29). Black MSM with recent convictions were more likely to have a sexually transmitted infection at 6 months (AOR = 3.97; 95% CI 1.58-9.94), while those who were unstably housed were more likely to have a sexually transmitted infection at 12 months (AOR = 1.71; 95%CI 1.02 = 2.86). There were no city of residence and hardship interaction effects on HIV risks. Hardships are important factors that influence HIV risk for Black MSM. Integrating strategies that address structural factors that influence HIV risk may enhance HIV prevention interventions implementation efforts.

    Full Text Available This paper emphasizes that for a nation to revitalize in terms of development, not only does it need to evaluate in terms of GDP growth rate, but also has to consider the Quality of Life of its citizen and their human happiness. There is strong correlation between macro-economic development parameters like health, education, GDP growth rate and Quality of Life Index, expressed through HDI. It also has correlation with subjective quality of life based on the perception of urban socio economic classes, as measured in this study. The subjective quality of life is studied through five parameters like Quality of house, education, health care, transportation and recreation facilities. Human happiness is evaluated through the perception of respondents towards change in their financial conditions and consumption expenditure influencing their quality of life. This empirical research through spearman’s rank correlation tried to establish the relationship between macro-economic indicators with the quality of life parameters as perceived by people. The study was conducted in Mumbai, and its suburban areas .with a sample of 850 respondents taken through structured questionnaire, during 2012-13. It was observed from A. T. Kearney’s GRDI report that India was ranking between first five positions, consistently in terms of Modern Trade Retail Business since 2000. The managerial implication of the study highlights the association of quantitative economic development with larger aspect of human development, for the policy makers to understand the various areas which needs to be taken care to cater towards revitalizing the development of the nation

    We assessed associations between discrimination and health-related quality of life among black and white men and women in the United States. We examined data from the National Health Measurement Study, a nationally representative sample of 3,648 adults aged 35-89 in the non-institutionalized US population. These data include self-reported lifetime and everyday discrimination as well as several health utility indexes (EQ-5D, HUI3, and SF-6D). Multiple regression was used to compute mean health utility scores adjusted for age, income, education, and chronic diseases for each race-by-gender subgroup. Black men and women reported more discrimination compared to white men and women. Health utility tended to be worse as reported discrimination increased. With a few exceptions, differences between mean health utility scores in the lowest and highest discrimination groups exceeded the 0.03 difference generally considered to be a clinically significant difference. Persons who experienced discrimination tended to score lower on health utility measures. The study also revealed a complex relationship between experiences of discrimination and race and gender. Because of these differential social and demographic relationships caution is urged when interpreting self-rated health measures in research, clinical, and policy settings.

    Prior research indicates an association between exposure to trauma (e.g., being victimized) and perpetration of crime, especially in the context of chronic victimization. This study examines the relationship between trauma exposure, posttraumatic stress disorder (PTSD), and history of arrest and incarceration among a representative sample of black Americans from the National Survey of American Life (N = 5,189). One-third had a history of arrest, and 18 percent had a history of incarceration. Frequency of trauma exposure was associated with involvement with the criminal justice system. Relative to never experiencing trauma, experiencing ≥4 traumas was associated with elevated odds of arrest (odds ratio [OR] = 4.03), being jailed (OR = 5.15), and being imprisoned (OR = 4.41), all p history of trauma (OR = 2.18, p Americans.

    The diagnosis and treatment of femoroacetabular impingement (FAI) have increased steadily within the past decade, and research indicates clinically significant improvements after treatment of FAI with hip arthroscopy. This study examined the societal and economic impact of hip arthroscopy by high-volume surgeons for patients with FAI syndrome aged Economic and decision analysis; Level of evidence, 2. The cost-effectiveness of hip arthroscopy versus nonoperative treatment was evaluated by calculating direct and indirect treatment costs. Direct cost was calculated with Current Procedural Terminology medical codes associated with FAI treatment. Indirect cost was measured with the patient-reported data of 102 patients who underwent arthroscopy and from the reimbursement records of 32,143 individuals between the ages of 16 and 79 years who had information in a private insurance claims data set contained within the PearlDiver Patient Records Database. The indirect economic benefits of hip arthroscopy were inferred through regression analysis to estimate the statistical relationship between functional status and productivity. A simulation-based approach was then used to estimate the change in productivity associated with the change in functional status observed in the treatment cohort between baseline and follow-up. To analyze cost-effectiveness, 1-, 2-, and 3-way sensitivity analyses were performed on all variables in the model, and Monte Carlo analysis evaluated the impact of uncertainty in the model assumptions. Analysis of indirect costs identified a statistically significant increase of mean aggregate productivity of $8968 after surgery. Cost-effectiveness analysis showed a mean cumulative total 10-year societal savings of $67,418 per patient from hip arthroscopy versus nonoperative treatment. Hip arthroscopy also conferred a gain of 2.03 quality-adjusted life years over this period. The mean cost for hip arthroscopy was estimated at $23,120 ± $10,279, and the mean

    Full Text Available In Italy, the economic crisis of the last years has been characterized by recession, deflation, and unemployment. In addition to its broader effect on society, the crisis has deeply affected Italians’!everyday practices, their views, and their future goals. This is particularly true for young people, who can no longer rely on rising expectations. The paper presents the preliminary results of a qualitative study aimed at understanding how young people perceive and handle their everyday life in a social and working context so heavily influenced by income uncertainty, job insecurity, and a general lack of confidence in the future. Face-to-face in-depth interviews have been conducted in the metropolitan area of Milan (Italy.

    The economic recession produced a rapid rise of unemployment rates that was more visible in Southern European countries. There is evidence that unemployment correlates highly with individuals' poor life satisfaction. To analyse the relationship between life satisfaction, household composition and socioeconomic deprivation in people facing unemployment during the economic recession. A sample of 748 unemployed people from Lisbon (Portugal) completed a socio-demographic questionnaire, the Cantril's ladder of life scale, and the latent and manifest benefits of work scale (LAMB). Multiple regression analyses were used to test the associations between life satisfaction and all other variables. Partnered people report higher life satisfaction compared to singles. Financial deprivation and lack of structured time were the strongest factors negatively related to life satisfaction in both partnered and single people. Having children had a particular negative effect on the life satisfaction of partnered men; and living with an unemployed partner together with lack of social contact and high enforced activity had a negative effect on life satisfaction in partnered women. The heterogeneity of socioeconomic needs found by household composition bring practical policy implications for support actions targeting unemployed individuals in the unique context of economic recession.

    This study examined the sustainability of generating renewable diesel via hydrothermal liquefaction (HTL) of biomass from a rotating algal biofilm reactor. Pilot-scale growth studies and laboratory-scale HTL experiments were used to validate an engineering system model. The engineering system model served as the foundation to evaluate the economic feasibility and environmental impact of the system at full scale. Techno-economic results indicate that biomass feedstock costs dominated the minimum fuel selling price (MFSP), with a base case of $104.31per gallon. Life-cycle assessment results show a base-case global warming potential (GWP) of 80gCO2-eMJ(-1) and net energy ratio (NER) of 1.65 based on a well-to-product system boundary. Optimization of the system reduces MFSP, GWP and NER to $11.90Gal(-1), -44gCO2-eMJ(-1), and 0.33, respectively. The systems-level impacts of integrating algae cultivation with wastewater treatment were found to significantly reduce environmental impact. Sensitivity analysis showed that algal productivity most significantly affected fuel selling price, emphasizing the importance of optimizing biomass productivity. Copyright © 2016 Elsevier Ltd.

    There is a strong association between financial hardship and the experience of depression. Previous longitudinal research differs in whether this association is viewed as a contemporaneous relationship between depression and hardship or whether hardship has a role in the maintenance of existing depression. In this study we investigate the association between depression and hardship over time and seek to resolve these contradictory perspectives. We also investigate the consistency of the association across the lifecourse. This study reports analysis of two waves of data from a large community survey conducted in the city of Canberra and the surrounding region in south-east Australia. The PATH Through Life Study used a narrow-cohort design, with 6715 respondents representing three birth cohorts (1975-1979; 1956-1960; and 1937-1941) assessed on the two measurement occasions (4 years apart). Depression was measured using the Goldberg Depression Scale and hardship assessed by items measuring aspects of deprivation due to lack of resources. A range of measures of socio-economic circumstance and demographic characteristics were included in logistic regression models to predict wave 2 depression. The results showed that current financial hardship was strongly and independently associated with depression, above the effects of other measures of socio-economic position and demographic characteristics. In contrast, the effect of prior financial difficulty was explained by baseline depression symptoms. There were no reliable cohort differences in the association between hardship and depression having controlled for socio-demographic characteristics. There was some evidence that current hardship was more strongly associated with depression for those who were not classified as depressed at baseline than for those identified with depression at baseline. The evidence of the contemporaneous association between hardship and depression suggests that addressing deprivation may be an

    according to UNU-EHS methodology: 'exposure' and 'vulnerability', consisting of 'susceptibility', 'coping capacity' and 'adaptive capacity'. Relevant indicators for each block were selected and verified by statistical methods. The authors estimated the share of people potentially exposed to flooding with the help of geographic information system. The authors, using the technique of World Risk Index (2011), calculated sub-indices for each block, and made the maps. Areas with the highest socio-economic risks were identified on the Azov and the Black sea coast: Slavyansky, Krymsky, Krasnoarmeysky, Temryuksky and Primorsko-Akhtarsky municipal districts. On the third stage, the main purpose was to integrate and use both approaches in evaluation of socio-economic risks on micro-geographical level for different categories of the population and different industries (agriculture, utilities, etc.), using 'field' data. Field study was conducted in Slavyansky municipal district of Krasnodar region and included opinion polls, special interviews with businessmen and authorities, collection of municipal statistics and data from companies, etc. Vulnerability maps, speed evacuation maps, maps of possible locations of warning systems and maps of high insurance risks were developed. Proposals for improvement of legislation for coastal zones were prepared. The conducted research has shown the importance of both social ('vulnerability'), and economic ('damage') components of risk assessment. Using the previously discussed methods individually does not bring desired results because of deficiencies of Russian statistics. It is essential for accurate risk assessment to use an 'ensemble' of methods (statistical, field observations, etc.) on micro geographic level. The work has a practical importance for improving safety of local communities.

    To examine the economic burden (direct and indirect costs) of Alzheimer disease (AD) and to analyze the impact on health-related quality of life (HRQOL) for patients with AD and caregivers in 2001 in the Canary Islands, Spain. Two hundred thirty-seven patients (61% of those contacted) were recruited from the Alzheimer's Disease Association in the Canary Islands. Demographic, health resources utilization, informal care, indirect costs, and quality of life data were collected from primary caregivers of patients as proxy respondents. HRQOL was measured for patients and caregivers with the generic questionnaire EQ-5D. The average annual cost per patient with AD was 28,198 (36,144 US dollars). The most important categories of costs were for informal care and drugs. Costs increased with cognitive impairment with an average annual cost of 14,956 (19,171 US dollars) for mild, 25,562 (32,765 US dollars) for moderate, and 41,669 (53,411 US dollars) for severe patients. The total cost of patients with AD in Canary Islands was 259 (332 US dollars) million. The HRQOL with the EQ-5D social tariff was 0.29 for patients and 0.67 for caregivers. The EQ-5D VAS (thermometer) score was 42 for patients and 62 for caregivers. Direct health care costs of AD represented 2.4% of the total public health care expenditure in the Canary Islands. Across all severity levels, we estimated a total annual cost of 10 (13 US dollars) billion for AD patients older than 65 years in Spain. The degree of severity of the patients with AD substantially influenced the quality of life of the patients but not that of the caregivers.

    Full Text Available This paper presents some preliminaries results of a research that investigates the representations about race, color, Difference, Prejudgment and Racial Discrimination of the school’s agents teachers, employees and students on the quotidian of the History’s, Portuguese’s and Art’s classes of the first two year of the secondary education of a Belém-PA’s private school, in order to understand the place of the black people in the school pedagogic practices, regarding the obligation of touching racial subjects as established by the low 10.639/2003. Using the methodological and theoretic approach of Pierre Bourdieu and Roger Chartier, we analyzed the representations obtained by the non-participative observation in those classes. We realized that teachers almost didn’t know anything about the low 10.639/2003 and about the ethnic and racial question on Brazil, what brings as result the reproduction of racial prejudgment and discrimination by the students. Our analysis aims, from understanding the problems with teacher development, to understand the problems related to the ethnic and racial question at school and propose solutions.

    To provide data on the economic burden and health-related quality of life (HRQoL) associated with systemic sclerosis (SSc) in France and to raise awareness of the repercussions of this disease for patients and caregivers and on the health and social care system. A cross-sectional study was carried out on 147 patients recruited through the Association des Sclérodermiques de France (ASF), the French association for SSc patients. Data on the patients' use of resources were obtained retrospectively from an online questionnaire and costs were estimated by a bottom-up approach. The HRQoL patients and caregivers was assessed with the five-level EURQol-5 Dimension (EQ-5D-5L) health questionnaire. The average annual cost of SSc was estimated at EUR 22,459 per patient. Direct healthcare costs amounted to EUR 8452, direct non-healthcare formal costs to EUR 1606, direct non-healthcare informal costs to EUR 1875, and indirect costs resulting from patients' absence from the labour market to EUR 10,526. The main contributors to SSc costs were hospitalizations and early retirement. Mean EQ-5D utility scores were 0.49 for patients and 0.66 for caregivers. Although SSc is a rare disease, its economic burden from a societal perspective is substantial and the consequences for HRQoL are significant for both patients and caregivers in France, underscoring the need to develop tailored policies targeted at improving patients' care and reducing the long-term impact of SSc.

  5. Opportunities for biomaterials. Economic, environmental and policy aspects along their life cycle

    Little was known at the start of these studies regarding the environmental impacts of bulk chemicals production from biomass and whether they could be produced economically. We have therefore analysed the entire life cycle of bio materials: the production of bio-based chemicals, the application of bio-based polymers in packaging and finally the waste treatment of biodegradable materials. Numerous bio-based chemicals offer economic opportunities, the extent of which depends on the prices of the petrochemical and bio-based feed-stocks and can be further improved by technological progress in the future. Almost all bio-based chemicals have lower carbon and energy footprints than their petrochemical counterparts, and savings can be substantially increased in the future. Bio-based materials also offer savings when used for a specific food packaging application, but these savings can become smaller when the comparison is made not per kg of material but considering the functionality and material properties. Biodegradable materials are advantageous in that they are suitable for biological waste treatment options whose carbon and energy footprints are currently at least equally good as incineration, but have the additional benefit of producing a soil conditioner which can improve soil carbon content. Finally, consistent policy measures supporting bio-based and/or biodegradable materials are necessary to ensure this market's success. The progress made in terms of quantifying the benefits, the start of major research and development programmes and the start-up of production facilities have increased the likelihood for many bio-based chemicals and plastics to enter the market. So there are clear opportunities for bio materials, but policy measures are needed to ensure that they can start competing on a larger scale.

  6. Life history, code of honor, and emotional responses to inequality in an economic game.

    The code of honor, which is characterized by a preoccupation with reputation and willingness to take retaliatory action, has been used extensively to explain individual and cultural differences in peoples' tendencies to behave aggressively. However, research on the relationship between the code of honor and emotional responses to social interactions has been limited in scope, focusing primarily on anger in response to insults and reputational threats. Here we broaden this scope by examining the relationship between code of honor and emotional reactions in response to an unfair economic exchange that resulted in unequal monetary earnings among 3 laboratory participants. We found that endorsement of the code of honor was related to anger and envy in response to unfair monetary distributions. Interestingly, code of honor predicted envy above and beyond what could be accounted for by anger, but the converse was not the case. This suggests that the code of honor influenced perceptions of how subjects viewed their own earnings relative to those of others, which consequently was responsible for their apparent anger as a result of the economic transaction. Furthermore, the unique relationship between code of honor and envy was present only for subjects who received unfair treatment and not for subjects who merely witnessed unfair treatment. Additionally, we replicated previous findings that harsh childhood environmental conditions are associated with endorsement of the code of honor, highlighting the potential value of incorporating a life history theoretical approach to investigating individual differences in endorsement of the code of honor.

    The UK Water Industry currently generates approximately 800GWh pa of electrical energy from sewage sludge. Traditionally energy recovery from sewage sludge features Anaerobic Digestion (AD) with biogas utilisation in combined heat and power (CHP) systems. However, the industry is evolving and a number of developments that extract more energy from sludge are either being implemented or are nearing full scale demonstration. This study compared five technology configurations: 1 - conventional AD with CHP, 2 - Thermal Hydrolysis Process (THP) AD with CHP, 3 - THP AD with bio-methane grid injection, 4 - THP AD with CHP followed by drying of digested sludge for solid fuel production, 5 - THP AD followed by drying, pyrolysis of the digested sludge and use of the both the biogas and the pyrolysis gas in a CHP. The economic and environmental Life Cycle Assessment (LCA) found that both the post AD drying options performed well but the option used to create a solid fuel to displace coal (configuration 4) was the most sustainable solution economically and environmentally, closely followed by the pyrolysis configuration (5). Application of THP improves the financial and environmental performance compared with conventional AD. Producing bio-methane for grid injection (configuration 3) is attractive financially but has the worst environmental impact of all the scenarios, suggesting that the current UK financial incentive policy for bio-methane is not driving best environmental practice. It is clear that new and improving processes and technologies are enabling significant opportunities for further energy recovery from sludge; LCA provides tools for determining the best overall options for particular situations and allows innovation resources and investment to be focused accordingly.

    Full Text Available The aim of this paper is to propose a methodology for supporting decision making in design activities; in case of new projects or retrofitting of existing buildings. A multidisciplinary approach is adopted; involving Real Estate Appraisal and Economic Evaluation of Project and Building Environmental Design. It is proposed a methodology for selecting the preferable solutions among technological options; considering both economic and environmental aspects; in terms of global performance. Assuming the principles of Life Cycle Thinking and Circular Economy focus is posed at the end-of-life stage. Attention is paid on disposal costs and residual value as relevant items enable to orient investment decisions. This is done through an approach for quantifying environmental indicators related to Life Cycle Assessment (Standard ISO 14040:2006; and economic indicators adopting the Life Cycle Costing (Standard ISO 15686:2008. The paper proposes a conjoint “economic-environmental indicator”. An application of Global Cost calculation is illustrated; including monetized environmental impacts (Embodied energy and Embodied carbon; disposal/dismantling costs and residual value. The result of the Global Cost calculation is expressed through a “synthetic economic-environmental indicator” in order to select; between two different technologies; the most viable solution for a multifunctional building glass façade project; in Northern Italy. The study demonstrates that the initial investment decisions depend on the design solutions; since the early stages; related to the whole building life cycle considering conjointly the construction-management phases and the end-of-life stage.

    Total knee replacement (TKR) is an effective treatment for end-stage knee osteoarthritis (OA). American racial minorities undergo fewer TKRs than Whites. We estimated quality-adjusted life years (QALYs) lost for Black knee OA patients due to differences in TKR offer, acceptance, and complication rates. We used the Osteoarthritis Policy Model, a computer simulation of knee OA, to predict QALY outcomes for Black and White knee OA patients with and without TKR. We estimated per-person QALYs gained from TKR as the difference between QALYs with current TKR use and QALYs when no TKR was performed. We estimated average, per-person QALY losses in Blacks as the difference between QALYs gained with White rates of TKR and QALYs gained with Black rates of TKR. We calculated population-level QALY losses by multiplying per-person QALY losses by the number of persons with advanced knee OA. Finally, we estimated QALYs lost specifically due to lower TKR offer and acceptance and higher complications among Black knee OA patients. Black men and women gain 64,100 QALYs from current TKR use. With white offer and complications rates, they would gain an additional 72,000 QALYs. Because these additional gains are unrealized, we call this a loss of 72,000 QALYs. Black Americans lose 67,500 QALYs because of lower offer, 15,800 QALYs because of lower acceptance, and 2,600 QALYs because of higher complications. Black Americans lose 72,000 QALYs due to disparities in TKR offer and complication rates. Programs to decrease disparities in TKR use are urgently needed. This article is protected by copyright.

    What does a science writer do all day? In a tough job market and the pressures of the publish-or-perish life, careers outside academia are enticing. But it's not just a matter of swapping research papers for news stories, or adapting course lectures to magazine articles. I am a former academic scientist (with a PhD in physics and astronomy, as well as six years of university teaching) who now works as a freelance science journalist. In this talk, I'll share my experiences, along with a brief guide to the science-writing life. Along the way, we'll touch on misconceptions ("I love teaching, so science writing should be easy!"), bad attitudes ("dumbing down" is a concept that should be nuked from orbit), and the joys of sharing science with others. There are some hard truths: don't choose science writing because you think it's an easy option compared with academic research. Nevertheless, it's a rewarding profession, and one that allows you to remember the love of science — and share that love with large numbers of other people.

  11. Life insurance, financial development and economic growth in South Africa: An application of the autoregressive distributed lag model

    Full Text Available The life insurance sector may contribute to economic growth by its very mechanism of savings mobilisation and thereby performing an intermediation role in the economy. This ensures that capital is provided to deficient units who are in need of capital to finance their working capital requirements and invest in technology thereby resulting in an increase in output. In this way, it could be argued that life insurance development spurs financial development. In this article we investigate the causal relationship between the life insurance sector, financial development and economic growth in South Africa for the period 1990 to 2012 by applying the ARDL bounds testing procedure. We make use of life insurance density as the proxy for life insurance development, real per capita growth domestic product as the proxy for economic growth and real broad money per capita as the proxy for financial development. We test for cointegration amongst the variables by applying the bounds test and then proceed to test for Granger causality based on the error correction model. Our results confirm that the variables are cointegrated and move in tandem to each other in the long-run. The results also indicate that the direction of causality runs from the economy to the life insurance sector in the short-run which is consistent with the “demand-following” insurance-growth hypothesis. There is also evidence of bidirectional Granger causality running from the economy to financial development and vice versa, both in the long-run and short-run. The results also reveal that life insurance complements financial development in bringing about economic growth further lending credence to the “complementarity” hypothesis

  12. Development of a support system to make economic and technical assessments for the issues relating to plant life extension

    1994-01-01

    To realize the life extension of nuclear power plants, overall evaluation for the plant is required, which covers technology, economy such as cost of repair or/and replacement of components, and regal regulations for licensing. A prototype of integrated assessment support system for life extension ''INPLEX'' have developed in order to evaluate the technical and economic issues relating to the plant life extension and to make a life extension scenario. Analysis procedure of INPLEX is as follows. A comparison of the cost between the life extension and the reconstruction is made to see whether the life extension is cost effective or not. Next, components required detailed assessments are selected, and the residual life assessment of these components are made. After those procedures life extension measures are selected and the implementation time schedule is set on the basis of the formulas for predicting the degradation of the components and the component reliability data. Finally the implementation time schedule is optimized from the viewpoint of economy, and the life extension scenario is proposed. INPLEX also has the data base ''PRINS'', in which information and data related to life extension are registered, such as component degradation experiences, degradation management methodologies, degradation mitigation measures, and so on. PRINS can be referred at any time during the operation of INPLEX

    This study examined the occurrence of low/high burnout among women and the demographic/socio-economic, work, life-style, and health "correlates" of high burnout. The sample consisted of 6.000 randomly selected women from the general population, of which 3.591 participated. The design was cross-sectional. The univariate analyses showed that about 21% of the women had high burnout, and compared to those with low burnout, they were more often younger, divorced, blue-collar workers, lower educated, foreigners, on unemployment/retirement/sick-leave, financially strained, used more medication and cigarettes, reported higher work demands and lower control/social support at work, more somatic problems (e.g. pain) and depression. The regression analysis showed that only age, sick-leave, financial strain, medication, work demands, depression and somatic ailments were independently associated with high burnout. Thus, women with high burnout were apparently faring poorly financially, emotionally and physically. Considering our findings, interventions to alleviate their problems may be necessary. We may have provided new insights into women's burnout experiences, but longitudinal studies are warranted to firmly identify "determinants" of burnout.

    This research has appraised the quality of life (QL) of diabetics type 1 member of Associação dos Diabéticos de Itabuna (ASDITA) and has verified their correlation between clinic variable and social-demographic situation of this group. Thirty-four patients (gamma = 88%, epsilon = 5%; 53% female, age 20.4 +/- 8.4 years, diagnostic time 5.7 +/- 4.9 year) have participated in this research, data showed weight and height after the interview and measuring. The social-demographic profiles of this group revealed family income of 0.7 +/- 0.56 of minimal salary, 53% had elementary school level and 64.7% were students. In avarage, the QL was regular (58.8%). QL has not been influenced by the level of education, ethnology, occupation, BMI, daily shot of insulin, or glicemic monitorization profile but woman, adult, diagnostic time more than ten years, little family income have had the worst QL. The QL of the searched patients has been less than what several publications have showed, but additional researches are necessary to have better comparisons between diabetics with socio-economical and cultural conditions similar to the ones observed in this research.

  15. Market disruption, cascading effects, and economic recovery:a life-cycle hypothesis model.

    Sprigg, James A.

    2004-11-01

    This paper builds upon previous work [Sprigg and Ehlen, 2004] by introducing a bond market into a model of production and employment. The previous paper described an economy in which households choose whether to enter the labor and product markets based on wages and prices. Firms experiment with prices and employment levels to maximize their profits. We developed agent-based simulations using Aspen, a powerful economic modeling tool developed at Sandia, to demonstrate that multiple-firm economies converge toward the competitive equilibria typified by lower prices and higher output and employment, but also suffer from market noise stemming from consumer churn. In this paper we introduce a bond market as a mechanism for household savings. We simulate an economy of continuous overlapping generations in which each household grows older in the course of the simulation and continually revises its target level of savings according to a life-cycle hypothesis. Households can seek employment, earn income, purchase goods, and contribute to savings until they reach the mandatory retirement age; upon retirement households must draw from savings in order to purchase goods. This paper demonstrates the simultaneous convergence of product, labor, and savings markets to their calculated equilibria, and simulates how a disruption to a productive sector will create cascading effects in all markets. Subsequent work will use similar models to simulate how disruptions, such as terrorist attacks, would interplay with consumer confidence to affect financial markets and the broader economy.

    Full Text Available Design of ACM life cycle is defined with respect to traffic load acting on the pavement and road class for a period of about 20 years. In practice, reconstruction is usually pending until the end of the life cycle after which the reconstruction takes place and the original materials are replaced by new materials. Life cycle of the pavement construction in road structure is significantly longer than that of the ACM; it is therefore necessary to consider ACM from a long term viewpoint, that is, exceeding their life expectancy. This paper describes a methodology which consists of analytical calculations, experimental measurements, and optimization of the ACM life cycle with the use of a rehabilitation action to provide new physical properties of pavement surfacing in different periods of the original life cycle. The aim is to attain maximal economic effectiveness, by minimizing financial costs for rehabilitation and maintenance and economic costs of road user. Presented method allows deriving optimal life cycle from various rehabilitation alternatives for particular ACM with the fact that all the necessary parameters are derived from specific experimental measurements and calculations. The method is applicable to all types of ACM materials; however, for each material, it is necessary to carry out the necessary measurements and tests. The article describes the methodology and case study results for a particular type of ACM material.

    Early growth is associated with blood pressure measured on one occasion, but whether early life growth patterns are associated with longitudinal blood pressure trajectories is under-researched. Therefore, we sought to examine the association between early growth and blood pressure trajectories from childhood to adulthood. Blood pressure was measured on 7 occasions between ages 5 and 18 years in the Birth to Twenty cohort study, and conditional variables for growth in infancy and mid-childhood were computed from anthropometric measures (n=1937, 52% girls). We used a group-based trajectory modeling approach to identify distinct height-adjusted blood pressure trajectories and then tested their association with growth between birth and mid-childhood adjusting for several covariates. Three trajectory groups were identified for systolic and diastolic blood pressure: lower, middle, and upper in boys and girls, separately. In boys, predictors of the middle or upper systolic blood pressure trajectories versus the lower trajectory were in birth weight (odds ratio 0.75 [95% confidence interval 0.58-0.96] per SD) and relative weight gain in infancy (4.11 [1.25-13.51] per SD). In girls, greater relative weight gain and linear growth in both infancy and mid-childhood were consistently associated with an almost 2-fold higher likelihood of being in the upper versus lower systolic blood pressure trajectory. The associations for the diastolic blood pressure trajectories were inconsistent. These findings emphasize the importance of identifying children at risk of progression to high blood pressure. Accelerated growth in infancy and mid-childhood may be a key target for early life intervention in prevention of elevated blood pressure progression. © 2016 American Heart Association, Inc.

    The Aday-Andersen model was used as a framework for investigating the contribution of immigration status (i.e., nativity and acculturation), socioeconomic factors, health care access, health status, and health insurance to usual source of health care (USOC) in a nationally representative sample of African American (n=551) and Caribbean Black men (n=1,217). We used the 2001-2003 National Survey of American Life, a nationally representative household survey of non-institutionalized U.S. Blacks to conduct descriptive and logistic regression analyses. Older age, more health conditions, neighborhood medical clinic access, and health insurance were associated with higher odds of reporting a USOC. Odds were lower for men with lower-middle incomes and poorer mental health status. Having health insurance was associated with higher odds of reporting a USOC for African American men but lower odds among Caribbean Black men. Odds were higher in the presence of more health conditions for African American men than for Caribbean Black men. Health care reform policies aimed solely at increasing health insurance may not uniformly eliminate USOC disparities disfavoring U.S. and foreign-born non-Hispanic Black men.

    Studies on the environmental analysis of biofuels by fast pyrolysis and hydroprocessing (BFPH) have so far focused only on the environmental impacts from direct emissions and have included few indirect emissions. The influence of ignoring some indirect emissions on the environmental performance of BFPH has not been well investigated and hence is not really understood. In addition, in order to avoid shifting environmental problems from one medium to another, a comprehensive assessment of environmental impacts caused by the processes must quantify the environmental emissions to all media (air, water, and land) in relation to each life cycle stage. A well-to-wheels assessment of the total environmental impacts resulting from direct emissions and indirect emissions of a BFPH system with corn stover is conducted using a hybrid life cycle assessment (LCA) model combining the economic input-output LCA and the process LCA. The Tool for the Reduction and Assessment of Chemical and other environmental Impacts (TRACI) has been used to estimate the environmental impacts in terms of acidification, eutrophication, global climate change, ozone depletion, human health criteria, photochemical smog formation, ecotoxicity, human health cancer, and human health noncancer caused by 1 MJ biofuel production. Taking account of all the indirect greenhouse gas (GHG) emissions, the net GHG emissions (81.8 g CO 2 eq/MJ) of the biofuels are still less than those of petroleum-based fuels (94 g CO 2 eq/MJ). Maize production and pyrolysis and hydroprocessing make major contributions to all impact categories except the human health criteria. All impact categories resulting from indirect emissions except eutrophication and smog air make more than 24% contribution to the total environmental impacts. Therefore, the indirect emissions are important and cannot be ignored. Sensitivity analysis has shown that corn stover yield and bio-oil yield affect the total environmental impacts of the biofuels

    I examined the frequency and developmental timing of traumatic loss resulting from the health disparity of homicide among young Black men in Baltimore, Maryland. Using a modified grounded theory approach, I conducted in-depth semistructured interviews with 40 Black men (aged 18-24 years) from January 2012 to June 2013. I also constructed adapted life history calendar tools using chronologies of loss, and (1) provided a comprehensive history of loss, (2) determined a specific frequency of homicide deaths, (3) indicated participants' relationship to the decedents, and (4) identified the developmental timing of deaths. On average, participants knew 3 homicide victims who were overwhelmingly peers. Participant experiences of homicide death started in early childhood, peaked in adolescence, and persisted into emerging adulthood. The traumatic loss of peer homicide was a significant developmental turning point and disrupted participants' social networks. The traumatic loss of peer homicide was a prevalent life course experience for young Black men and identified the need for trauma- and grief-informed interventions. Future research is needed to examine the physical and psychosocial consequences, coping resources and strategies, and developmental implications of traumatic loss for young Black men in urban contexts.

    2015-01-01

    Highlights: • A lifecycle optimization model for distributed energy systems is developed. • Model estimates costs and environmental impacts of meeting the building energy demand. • Design and operating strategies to reduce costs and environmental impacts are discussed. • Pareto frontiers of costs vis-à-vis environmental impacts are presented. • Distributed generation can reduce the environmental impacts of the building sector. - Abstract: Distributed generation, namely cogeneration and solar technologies, is expected to play an important role in the future energy supply mix in buildings. This calls for a methodological framework to assess the economic and environmental performance of the building sector when such technologies are employed. A life-cycle model has been developed, combining distributed generation and conventional sources to calculate the cost and environmental impacts of meeting the building energy demand over a defined planning period. Three type of cogeneration technologies, solar photovoltaic and thermal, as well as conventional boilers along with the Portuguese electricity generation mix comprise the energy systems modeled. Pareto optimal frontiers are derived, showing the trade-offs between different types of impacts (non-renewable cumulative energy demand, greenhouse gas emissions, acidification, eutrophication) and cost to meet the energy demand of a commercial building. Our analysis shows that according to the objective to employ distributed generation (reducing cost or environmental impacts), a specific design and operational strategy for the energy systems shall be adopted. The strategies to minimize each type of impact and the associated cost trade-offs by exploring the solutions located on the Pareto optimal frontiers are discussed

  5. Environmental life cycle assessment and techno-economic analysis of triboelectric nanogenerators

    As the world economy grows and industrialization of the developing countries increases, the demand for energy continues to rise. Triboelectric nanogenerators (TENGs) have been touted as having great potential for low-carbon, non-fossil fuel energy generation. Mechanical energies from, amongst others, body motion, vibration, wind and waves are captured and converted by TENGs to harvest electricity, thereby minimizing global fossil fuel consumption. However, only by ascertaining performance efficiency along with low material and manufacturing costs as well as a favorable environmental profile in comparison with other energy harvesting technologies, can the true potential of TENGs be established. This paper presents a detailed techno-economic lifecycle assessment of two representative examples of TENG modules, one with a high performance efficiency (Module A) and the other with a lower efficiency (Module B) both fabricated using low-cost materials. The results are discussed across a number of sustainability metrics in the context of other energy harvesting technologies, notably photovoltaics. Module A possesses a better environmental profile, lower cost of production, lower CO2 emissions and shorter energy payback period (EPBP) compared to Module B. However, the environmental profile of Module B is slightly degraded due to the higher content of acrylic in its architecture and higher electrical energy consumption during fabrication. The end of life scenario of acrylic is environmentally viable given its recyclability and reuse potential and it does not generate toxic gases that are harmful to humans and the environment during combustion processes due to its stability during exposure to ultraviolet radiation.

    The importance of economic well-being is recognised in the recent UK Government policy. Older people may be particularly vulnerable to economic fluctuations as they are reliant on fixed incomes and assets, which are reducing in value. Within the literature, little is understood about the impact of the current economic downturn on people's general quality of life and well-being and, in particular, there is little research on the financial experiences and capability of the older age group, a concern in light of the ageing UK population. This article reports a qualitative research study into the nature of older peoples' vulnerability by exploring their perceptions of the impact of the economic recession on their well-being and quality of life. It explores specifically a group of older people who are not the poorest within the ageing population, but who may be described as the 'asset rich-income poor' group. Key themes relate to the impact of the recession on the costs of essential and non-essential items and dimensions of mental, physical and social well-being. Implications for health and social care practice in meeting the needs of older people during times of economic recession are then explored. The paper adds to the debate by demonstrating that the recession is having adverse consequences for older people's quality of life in terms of economic, mental and social well-being, although there is also evidence that some of them are equipped with certain resilience factors due to their money management and budgeting skills. © 2012 Blackwell Publishing Ltd.

    Full Text Available Black pepper is one of the most popular spice traded around the globe, either in dried grain form or in bulky powder. However, for retailing purpose both are usually packaged in plastic film. This research was conducted to predict the shelf life of packaged black pepper (both dried grain and powder by applying isotherm sorption and Labuza models. Initial moisture content of dried grain was 12.17 % d.b and for the powder was 10.27 % d.b. The shelf life of black pepper calculated for the dried grain was longer than the powder. When stored at 90 % RH, the dried grain black pepper packaged in HDPE demonstrated the longest shelf life which was equal to 2187 days and for the powder equal to 2037 days. The volatile oil loss for dried grain black pepper after 30 days of preservation was 1.36 % and for the powder was 40.82%.

    National trends show dramatic increases in the incidence of HPV-related head and neck squamous cell carcinomas (HNSCCs) among black and white males. Using cases identified through the National Cancer Data Base, we assessed factors associated with HPV 16- or 16/18 positive HNSCCs among non-Hispanic black and white males diagnosed in the U.S. between 2009 and 2013. This sample included 21,524 HNSCCs with known HPV status. Adjusted relative risks (RRs) and 95% confidence intervals (CIs) were estimated using log-binomial regression. Compared to those with HPV-negative tumors, male patients diagnosed with HPV-positive HNSCCs were non-Hispanic white, younger at diagnosis, lived in zip-code areas with higher median household income and higher educational attainment, had private health insurance and no reported comorbidities at diagnosis. Although the risk of HPV-positive HNSCCs increased with measures of higher area-level socioeconomic status, the effect was stronger for non-Hispanic black males (RR Adjusted =1.76, 95% CI 1.49-2.09) than for whites (RR Adjusted =1.12, 95% CI 1.08-1.16). The peak age for diagnosis of HPV-positive HNSCCs occurred in those diagnosed at 45-49 years (RR Adjusted =1.57, 95% CI 1.42-1.73). Oropharyngeal tumors were strongly associated with HPV-positivity (RR Adjusted =4.32, 95% CI 4.03-4.63). In the analysis restricted to oropharyngeal anatomic sites, similar patterns persisted. In our analysis, measures of economic advantage were associated with an increased risk of HPV-positive HNSCCs. In order to develop effective interventions, greater understanding of the risk factors for HPV-positive HNSCCs is needed among both high-risk males and their healthcare providers.

    Full Text Available Background Replacement of fossil fuel based energy with biochar-based bioenergy production can help reduce greenhouse gas emissions while mitigating the adverse impacts of climate change and global warming. However, the production of biochar-based bioenergy depends on a sustainable supply of biomass. Although, Northwestern Ontario has a rich and sustainable supply of woody biomass, a comprehensive life cycle cost and economic assessment of biochar-based bioenergy production technology has not been done so far in the region. Methods In this paper, we conducted a thorough life cycle cost assessment (LCCA of biochar-based bioenergy production and its land application under four different scenarios: 1 biochar production with low feedstock availability; 2 biochar production with high feedstock availability; 3 biochar production with low feedstock availability and its land application; and 4 biochar production with high feedstock availability and its land application- using SimaPro®, EIOLCA® software and spreadsheet modeling. Based on the LCCA results, we further conducted an economic assessment for the break-even and viability of this technology over the project period. Results It was found that the economic viability of biochar-based bioenergy production system within the life cycle analysis system boundary based on study assumptions is directly dependent on costs of pyrolysis, feedstock processing (drying, grinding and pelletization and collection on site and the value of total carbon offset provided by the system. Sensitivity analysis of transportation distance and different values of C offset showed that the system is profitable in case of high biomass availability within 200 km and when the cost of carbon sequestration exceeds CAD $60 per tonne of equivalent carbon (CO2e. Conclusions Biochar-based bioenergy system is economically viable when life cycle costs and environmental assumptions are accounted for. This study provides a medium scale

    2009-07-01

    Full Text Available Abstract Background Depressive and anxiety symptoms in older adults could develop into significant health problems with detrimental effects on quality of life and a possibly poor prognosis. Therefore, there is a need for preventive interventions which are at once effective, acceptable and economic affordable. Methods and design This paper describes the design of a study evaluating "The stories we live by", a preventive life-review group intervention, which was recently developed for adults of 55 years and over with depressive and anxiety symptoms. Both clinical and economic effectiveness will be evaluated in a pragmatic randomized controlled trial. The participants in the intervention condition will receive the 8-session preventive intervention. The participants in the control condition will have access to usual care. Clinical end-terms are depressive and anxiety symptoms, current major depressive episode, quality of life and positive mental health post-treatment (3 months after baseline and at follow-ups (6 and 12 months after baseline. Additional goals of this study are to identify groups for whom the intervention is particularly effective and to identify the therapeutic pathways that are vital in inducing clinical change. This will be done by analyzing if treatment response is moderated by demographics, personality, past major depressive episodes, important life events and chronically disease, and mediated by reminiscence functions, perceived control, automatic positive thoughts and meaning in life. Finally the cost-effectiveness of the intervention relative to care as usual will be assessed by computing incremental costs per case of depression and anxiety avoided (cost-effectiveness and per quality adjusted life year (QALY (cost utility. Discussion It is expected that both the life-review intervention and its evaluation will contribute to the existing body of knowledge in several ways. First, the intervention is unique in linking life

    Hessel, Philipp; Avendano, Mauricio

    2013-11-01

    To examine whether economic conditions at the time of leaving school or college are associated with physical functioning in later life among cohorts in 11 European countries. Data came from 10,338 participants in the Survey of Health, Ageing and Retirement in Europe (SHARE) aged 50-74 who left school or college between 1956 and 1986. Data on functional limitations, as well as employment, marriage, and fertility retrospective histories were linked to national unemployment rates during the year individuals left school. Models included country-fixed effects and controls for early-life circumstances. Greater unemployment rates during the school-leaving year were associated with fewer functional limitations at ages 50-74 among men (rate ratio 0.63, 95% confidence interval 0.47-0.83), but more physical functioning limitations among women (rate ratio 1.30, 95% confidence interval 1.13-1.50), particularly among those with (post-)secondary education. Economic conditions at the age of leaving school were associated with several labor market, marriage, fertility, and health behavior outcomes, but controlling for these factors did not attenuate associations. Results were similar in models that controlled for selection into higher education due to measured covariates. Worse economic conditions during the school-leaving year predicted better health at later life among men but worse health among women. Both selection and causation mechanisms may explain this association. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Du Bois and Frazier studied the Black family from a perspective that integrated sociological and historical analysis. Du Bois and Frazier analyzed the progression of the Black family from slavery to emancipation to the Jim Crow era. In the late 1890's Du Bois looked at the social structure of the Black community and painted a picture of a group of people who were uneducated and poverty stricken. Frazier provided a more positive spin. He documented a change in the 1920's -1930's that showed upward mobility, more educational attainment, property ownership, better jobs, better living conditions, and a less segregated environment in the North.

    Quality of life (QOL) is an important outcome following the treatment of disease. It is influenced by physical, psychological, social and economic factors. We proposed to determine the effect of some socioeconomic factors on QOL of patients on CAPD. A cross sectional study in which all patients on CAPD attending three clinics attached to the University of the Witwatersrand, Johannesburg were recruited excluding those with intercurrent illness. The WHO quality of life instrument, WHOQOL-Bref, was used to measure QOL. The patients were grouped according to marital status, highest level of education attained, income, employment, and QOL domain scores were compared using ANOVA and Student t test. A total of 140 patients comprising 80 males and 40 females were assessed. The mean age of patients was 41.9 ± 11.5 years, 95%of patients were black, 44.3% married, 69.3% had secondary education, 22% were employed and 51.4% had a monthly income of less than five thousand Rand (500 US dollars). Single patients scored better in the social relationships domain compared to separated patients (p=0.02, CI: 5.6-32.9). The group with secondary education scored low in the psychological domain compared with those with primary education (p=0.02, CI: 1.35-15.8) and those with tertiary education (p=0.02, CI: 1.72-18.07).The highest income group had best scores in all domains except the physical domain. Those in employment had better scores in the physical domain (p=0.04, CI: 0.356-12.549). Income had the most impact on QOL in study participants.

    The poor health status of black Americans was a widely recognized fact during the first third of the twentieth century. Excess mortality in black communities was frequently linked to the infectious disease tuberculosis, which was particularly menacing in densely populated urban settings. As health authorities in large cities struggled to keep pace with the needs of citizens, private charities worked to launch community-oriented attacks against the deadly disease. In 1914 a novel experiment to address excess mortality among blacks was launched in Philadelphia. The success of the health promotion campaign initiated by the Henry Phipps Institute and the Whittier Centre, two private charitable associations, has been attributed primarily to the presence of black clinicians, in particular public health nurse Elizabeth Tyler. This study suggests that community health efforts also rest on partnerships between like-minded organizations and coalition building.

    By some accounts, global economic inequality is at its highest point on record. The pernicious effects of this broad societal trend are striking: Rising inequality is linked to poorer health and well-being across countries, continents, and cultures. The economic and psychological forces that perpetuate inequality continue to be studied, and in this theoretical review, we examine the role of daily experiences of economic inequality-the communication of social class signals between interaction partners-in this process. We theorize that social class signals activate social comparison processes that strengthen group boundaries between the haves and have nots in society. In particular, we argue that class signals are a frequent, rapid, and accurate component of person perception, and we provide new data and analyses demonstrating the accuracy of class signaling in 60-s interactions, Facebook photographs, and isolated recordings of brief speech. We suggest that barriers to the reduction of economic inequality in society arise directly from this class signaling process through the augmentation of class boundaries and the elicitation of beliefs and behaviors that favor the economic status quo.

    Full Text Available The article is aimed at studying the theoretical aspects of changes in the dynamics of economic effect in the processes of management of life cycle of the industrial innovations at the stage of their commercialization. On the basis of an analysis of the scientific papers by the domestic and the foreign authors on methods of commercialization of the innovative products, the current status and essence of the definitions of «innovation», «commercialization», and «economic effect» was researched. Possibilities of managing the duration of the stage of commercialization of innovations were researched. It has been proposed to implement extension of the maturity stage of the life cycle of innovation by reducing the phase of designing and creating the innovative product and, as a consequence, change of value of the cumulative economic effect. Further researches should focus on the interdependence of development costs, creating an innovation and time period for the implementing, as well as determine the mechanism for calculating the quantitative indicators of commercialization of innovations.

    2012-01-01

    Backgrounds This study examines social inequalities in life expectancy and mortality during the transition period of the Korean economic crisis (1993–2010) among Korean adults aged 40 and over. Methods Data from the census and the national death file from the Statistics Korea are employed to calculate life expectancy and age-specific-death-rates (ASDR) by age, gender, and educational attainment for five years: 1993, 1995, 2000, 2005, and 2010. Absolute and relative differences in life expectancy and Age-Specific Death Rates by educational attainment were utilized as proxy measures of social inequality. Results Clear educational gradient of life expectancy was observed at age 40 by both sexes and across five time periods (1993, 1995, 2000, 2005, and 2010). The gradient became notably worse in females between 1993 and 2010 compared to the trend in males. The educational gradient was also found for ASDR in all five years, but it was more pronounced in working age groups (40s and 50s) than in elderly groups. The relative disadvantage of ASDR among working age Korean adults, both males and females, became substantially worse over time. Conclusions Social inequalities in life expectancy and ASDR of the working age group across socioeconomic status over time were closely related to the widening of the social difference created by the macroeconomic crisis and the expansion of neo-liberalism in Korea.

    Refrigeration alone or in combination with other technologies represents the main tool used in the last decades to preserve the freshness of black truffles. This is principally due to the delicateness and vulnerability of this edible hypogeous fungus, so that other invasive preservation practices cannot be adopted. However, the proliferation of some microbial species during the cold storage still represents an unsolved problem. Pseudomonads are among the main spoiler bacteria responsible for the deterioration of refrigerated black truffles. Their growth ability at low temperatures requires the use of additional hurdles to prolong the shelf-life of truffles without altering their major features. The use of natural compounds may represent an alternative system for the biocontrol of this kind of product. Specifically, gallic acid (GA) is a phenolic acid naturally present in different foods, whose effectiveness was in vitro demonstrated against Pseudomonas spp. In our study, we reported the antimicrobial activity expressed by GA not only in vitro, using as target bacteria Pseudomonas putida DSMZ 291 T , P. fluorescens DSMZ 50090 T , P. fragi DSMZ 3456 T and Pseudomonas spp. P30-4, previously isolated from black truffles, but also in situ on fresh black truffles stored at 4°C for 28days. Our results showed Minimum Inhibitory Concentrations (MIC) of 2.5mg/mL GA for all tested strains, except for P. fluorescens DSMZ 50090 T , having a MIC corresponding to 5mg/mL GA. The Minimum Bactericidal Concentration (MBC) was 10mg/mL for all strains. The analysis of kinetic parameters showed that the survival declined passing from 2.5 to 10mg/mL GA concentrations, with P. fluorescens confirmed to be the most resistant strain. Moreover, images obtained from Scanning Electron Microscopy revealed that Pseudomonas cells were strongly injured by the treatment with GA at 2.5mg/mL concentration, displaying visible pores on the cellular surfaces, absence of flagella and lysis with loss of

    Full Text Available Objective: To find out the relationship of collective social, economic, and cultural properties of a population on the perceived quality of life (QOL among old age people. Materials and Methods: In a community-based cross-sectional study, we analyzed information on a representative sample of 900 old age (aged > 60 years from 28 villages in Kollam district of Kerala. " WHO-Quality of Life - BREF questionnaire" was used. Ethical clearance from Institutional Ethics Committee was obtained. The mean scores for "perceived" QOL for domains such as physical health, psychological health, social relations, and control of environments were calculated. The three scales (social capital, cultural capital, and economic capital were standardized using z-score transformation to make them comparable. Using multiple linear regression, we calculated the independent effect of economic capital, social capital, and cultural capital on perceived QOL among old people adjusted for age, sex, and the presence of chronic disease. Results: For overall QOL, only cultural capital contributed significantly. An increase of one unit z-score cultural capital led to three units increase in overall QOL score (β = 3.362; 95% CI: 2.645-4.078. Social capital and cultural capital contributed significantly to the physical health domain of QOL. With one z-score increase in social capital and cultural capital, QOL score of physical health domain increased by 0.2 units (β = 0. 227; 95% CI: 0.020-0.434, and 0.5 (β = 0. 596; 95% CI: 0.384-0.808 units, respectively. Psychological health domain and environmental domain were affected by all three capitals significantly. But, the social relations domain was significantly affected only by cultural capital (β = 0. 576; 95% CI: 0.373-0.779. Conclusion: Hence, the policies for old people should envision retaining our cultural and social norms along with the economic interventions for a better palliative care.

    We report on life cycle assessment (LCA) of the economics, global warming potential and water (both for desalination and water use in operation) for a distributed concentrating solar combined heat and power (DCS-CHP) system. Detailed simulation of system performance across 1020 sites in the US combined with a sensible cost allocation scheme informs this LCA. We forecast a levelized cost of 0.25 kWh-1 electricity and 0.03 kWh-1 thermal, for a system with a life cycle global warming potential of ˜80 gCO2eq kWh-1 of electricity and ˜10 gCO2eq kWh-1 thermal, sited in Oakland, California. On the basis of the economics shown for air cooling, and the fact that any combined heat and power system reduces the need for cooling while at the same time boosting the overall solar efficiency of the system, DCS-CHP compares favorably to other electric power generation systems in terms of minimization of water use in the maintenance and operation of the plant. The outlook for water desalination coupled with distributed concentrating solar combined heat and power is less favorable. At a projected cost of 1.40 m-3, water desalination with DCS-CHP would be economical and practical only in areas where water is very scarce or moderately expensive, primarily available through the informal sector, and where contaminated or salt water is easily available as feed-water. It is also interesting to note that 0.40-1.90 m-3 is the range of water prices in the developed world, so DCS-CHP desalination systems could also be an economical solution there under some conditions.

    In "Global health 2035: a world converging within a generation," The Lancet Commission on Investing in Health (CIH) adds the value of increased life expectancy to the value of growth in gross domestic product (GDP) when assessing national well-being. To value changes in life expectancy, the CIH relies on several strong assumptions to bridge gaps in the empirical research. It finds that the value of a life year (VLY) averages 2.3 times GDP per capita for low- and middle-income countries (LMICs) assuming the changes in life expectancy they experienced from 2000 to 2011 are permanent. The CIH VLY estimate is based on a specific shift in population life expectancy and includes a 50 percent reduction for children ages 0 through 4. We investigate the sensitivity of this estimate to the underlying assumptions, including the effects of income, age, and life expectancy, and the sequencing of the calculations. We find that reasonable alternative assumptions regarding the effects of income, age, and life expectancy may reduce the VLY estimates to 0.2 to 2.1 times GDP per capita for LMICs. Removing the reduction for young children increases the VLY, while reversing the sequencing of the calculations reduces the VLY. Because the VLY is sensitive to the underlying assumptions, analysts interested in applying this approach elsewhere must tailor the estimates to the impacts of the intervention and the characteristics of the affected population. Analysts should test the sensitivity of their conclusions to reasonable alternative assumptions. More work is needed to investigate options for improving the approach.

    Full Text Available Sustainable Forest Management (SFM should be able to produce an optimal level of bundle of Ecosystem Services (ES, thus ensuring more resilient forest ecosystems also creating benefits for local population and human well-being. Yet, choosing between alternative forest management practices is not straightforward as it necessarily involves ES trade-offs. Forest management decisions have to reconcile the socio-economic and ecological contributions of forest ecosystems by fostering a synergistic relation between multiple ES while lowering ES trade-offs. The aim of the study is to analyze different forest management practices (selective and traditional thinning in black pine peri-urban forest in Central Italy, by investigating their contribution in terms of provisioning (wood production, cultural (recreational benefits, regulating (climate change mitigation ES. For each management option was performed: (1 the biophysical assessment of selected ES by using primary data and calculating indicators for wood production with special regard to biomass for energy use (living trees and deadwood volume harvested, recreational benefits (tourists’ preferences for each forest management practice, climate change mitigation (carbon sequestration in above-ground and below-ground biomass, and (2 the economic valuation of wood production, recreational benefits and climate change mitigation ES using direct and indirect methods (environmental evaluation techniques. The results show that the effects of the selective thinning on ES is higher that the effects of the traditional thinning. The economic value of the three ES provided by traditional and selective thinning are respectively: bioenergy production 154.2 € ha-1 yr-1 and 223.3 € ha-1 yr-1; recreational benefits 193.2 € ha-1 yr-1 and 231.9 € ha-1 yr-1; carbon sequestration 29.0 € ha-1 yr-1and 36.2 € ha-1 yr-1.

Mean (SE) utility scores for quality-of-life assessments among patients with GAD (15D, 0.783 [0.019]; EuroQoL EQ-5D, 0.589 [0.038]) were similar to those for patients who were 20 years older and reported somatic conditions such as Parkinson's disease or heart failure. Current evidence suggests that GAD is associated with substantial economic and humanistic impact on patients and health care systems. Future research should address economic evaluations from the private-payer perspective, studies related to the cost of underdiagnosed or untreated GAD, and full economic evaluations that incorporate longer clinical courses of the disorder.

    Full Text Available For economic evaluation of a highway development project, multiple criteria must be considered on a timeframe longer than the project implementation interval and a geographical area larger than the project zone. In this study, a framework is proposed based on the Network-Level Life Cycle Cost Analysis (NL-LCCA to assess the effect of highway development projects on mobility, safety, economy, environment and other monetizable criteria. In this approach, project impacts are estimated within physical boundaries of highway network over the network life cycle. This framework can be used as a decision-making support for evaluation and ranking of pre-defined development projects, proposing new cost-effective development projects, assessment of cost efficiency of existing highway network and budget allocation optimization.

    This paper summarizes the research of Monte Carlo simulation-based Economic, Energy and Environmental (3E) Life Cycle Assessment (LCA) of the three Biomass-based Fuel Ethanol (BFE) projects in China. Our research includes both theoretical study and case study. In the theoretical study part, 3E LCA models are structured, 3E Index Functions are defined and the Monte Carlo simulation is introduced to address uncertainties in BFE life cycle analysis. In the case study part, projects of Wheat-based Fuel Ethanol (WFE) in Central China, Corn-based Fuel Ethanol (CFE) in Northeast China, and Cassava-based Fuel Ethanol (CFE) in Southwest China are evaluated from the aspects of economic viability and investment risks, energy efficiency and airborne emissions. The life cycle economy assessment shows that KFE project in Guangxi is viable, while CFE and WFE projects are not without government's subsidies. Energy efficiency assessment results show that WFE, CFE and KFE projects all have positive Net Energy Values. Emissions results show that the corn-based E10 (a blend of 10% gasoline and 90% ethanol by volume), wheat-based E10 and cassava-base E10 have less CO 2 and VOC life cycle emissions than conventional gasoline, but wheat-based E10 and cassava-based E10 can generate more emissions of CO, CH 4 , N 2 O, NO x , SO 2 , PM 10 and corn-based E10 can has more emissions of CH 4 , N 2 O, NO x , SO, PM 10 .

    The medicinal plant Actaea racemosa L. (Ranunculaceae, aka black cohosh) is widely used to treat climacteric complaints as an alternative to hormone substitution. Recent trials prove efficacy and safety of the approved herbal medicinal products from extracts of pharmaceutical quality. This led to worldwide increasing sales. A higher demand for the plant material results in problems with economically motivated adulteration. Thus, reliable tools for herbal drug authentication are necessary. To develop an economical, plain, and rapid method to distinguish between closely related American and Asian Actaea species, using securely established and resilient analytical methods coupled to a chemometric evaluation of the resulting data. We developed and validated a RP-PDA-HPLC method including an extraction by ultra-sonication to determine the genuine contents of partly hydrolysis-sensitive polyphenols in Actaea racemosa roots and rhizomes, and applied it to a large number of 203 Actaea samples consisting of seven species. We were able to generate reliable data with regards to the polyphenolic esters in the samples. The evaluation of this data by principle component analysis (PCA) made a discrimination between Asian Actaea species (sheng ma), one American Actaea species (Appalachian bugbane), and A. racemosa possible. The developed RP-PDA-HPLC method coupled to PCA is an excellent tool for authentication of the Actaea racemosa herbal drug, and can be a powerful addition to the TLC methods used in the dedicated pharmacopoeias, and is a promising alternative to expensive and lots of expertise requiring methods.

    We connect the recent medical and economic literatures on the long-run effects of early-life conditions by analyzing the effects of economic conditions on the individual cardiovascular (CV) mortality rate later in life, using individual data records from the Danish Twin Registry covering births since the 1870s and including the cause of death. To capture exogenous variation of conditions early in life, we use the state of the business cycle around birth. We find significant negative effects of economic conditions around birth on the individual CV mortality rate at higher ages. There is no effect on the cancer-specific mortality rate. From variation within and between monozygotic and dizygotic twin pairs born under different conditions, we conclude that the fate of an individual is more strongly determined by genetic and household-environmental factors if early-life conditions are poor. Individual-specific qualities come more to fruition if the starting position in life is better.

    The effects of contextual risk on young children's behavior are not appropriately modeled. To model the effects of area and family contextual risk on young children's psychopathology. The final study sample consisted of 4,618 Millennium Cohort Study (MCS) children, who were 3 years old, clustered in lower layer super output areas in nine strata in the UK. Contextual risk was measured by socio-economic disadvantage (SED) at both area and family level, and by distal and proximal adverse life events at family level. Multivariate response multilevel models that allowed for correlated residuals at both individual and area level, and univariate multilevel models estimated the effect of contextual risk on specific and broad psychopathology measured by the Strengths and Difficulties Questionnaire. The area SED/broad psychopathology association remained significant after family SED was controlled, but not after maternal qualifications and family adverse life events were added to the model. Adverse life events predicted psychopathology in all models. Family SED did not predict emotional symptoms or hyperactivity after child characteristics were added to the model with the family-level controls. Area-level SED predicts child psychopathology via family characteristics; family-level SED predicts psychopathology largely by its impact on development; and adverse life events predict psychopathology independently of earlier adversity, SED and child characteristics, as well as maternal psychopathology, parenting and education.

    Summary Abstract South Africa (SA) is undergoing a rapid epidemiological transition and has the highest prevalence of obesity in sub-Saharan Africa (SSA), with black women being the most affected (obesity prevalence 31.8%). Although genetic factors are important, socio-cultural, environmental and behavioural factors, as well as the influence of socio-economic status, more likely explain the high prevalence of obesity in black SA women. This review examines these determinants in black SA women, and compares them to their white counterparts, black SA men, and where appropriate, to women from SSA. Specifically this review focuses on environmental factors influencing obesity, the influence of urbanisation, as well as the interaction with socio-cultural and socio-economic factors. In addition, the role of maternal and early life factors and cultural aspects relating to body image are discussed. This information can be used to guide public health interventions aimed at reducing obesity in black SA women. PMID:24051701

    2017-05-01

    Men's health has been generalized as prostate cancer (PCa) with a supporting cast of other health issues, such as testicular cancer (TCa). As a result, research and scholarship in these supporting topical areas may not receive appropriate attention.This may possibly lead to disease burden indicators failing to comprehensively assess overall affect from a specific outcome within the population. The following commentary provides an example of years of potential life lost (YPLL) and economic productivity as it relates to TCa to encourage diversity in male health research and scholarship topical areas. Overall incidence and mortality rates overwhelmingly support a disparate burden from PCa as compared to other male-specific outcomes, specifically, TCa. When factoring in YPLL and lost economic activity as a result of early death, that disparity essentially dissipates. This discussion will provide an alternative disposition on how males are affected by PCa and TCa. Although PCa has much larger mortality and incidence rates compared to TCa, the amount of life a man potentially lo ses (nearly quadrupled) if he would die of TCa as compared to PCa assists in balancing out the disparate aforementioned burden. Suggestions are offered to encourage scholarship attention equity as well as implications for future research in the field.

    The climate impact assessment of vehicle/fuel systems may be incomplete without considering short-lived climate forcers of black carbon (BC) and primary organic carbon (POC). We quantified life-cycle BC and POC emissions of a large variety of vehicle/fuel systems with an expanded Greenhouse gases, Regulated Emissions, and Energy use in Transportation model developed at Argonne National Laboratory. Life-cycle BC and POC emissions have small impacts on life-cycle greenhouse gas (GHG) emissions of gasoline, diesel, and other fuel vehicles, but would add 34, 16, and 16 g CO2 equivalent (CO2e)/mile, or 125, 56, and 56 g CO2e/mile with the 100 or 20 year Global Warming Potentials of BC and POC emissions, respectively, for vehicles fueled with corn stover-, willow tree-, and Brazilian sugarcane-derived ethanol, mostly due to BC- and POC-intensive biomass-fired boilers in cellulosic and sugarcane ethanol plants for steam and electricity production, biomass open burning in sugarcane fields, and diesel-powered agricultural equipment for biomass feedstock production/harvest. As a result, life-cycle GHG emission reduction potentials of these ethanol types, though still significant, are reduced from those without considering BC and POC emissions. These findings, together with a newly expanded GREET version, help quantify the previously unknown impacts of BC and POC emissions on life-cycle GHG emissions of U.S. vehicle/fuel systems.

    Full Text Available Abstract Background Patients with acquired brain damage (ABD have suffered a brain lesion that interrupts vital development in the physical, psychological and social spheres. Stroke and traumatic brain injury (TBI are the two main causes. The objectives of this study were to estimate the incidence and prevalence of ABD in the population of the Basque Country and Navarre in 2008, to calculate the associated cost of the care required and finally to assess the loss in health-related quality of life. Methods On the one hand, a cross-sectional survey was carried out, in order to estimate the incidence of ABD and its consequences in terms of costs and loss in quality of life from the evolution of a sample of patients diagnosed with stroke and TBI. On the other hand, a discrete event simulation model was built that enabled the prevalence of ABD to be estimated. Finally, a calculation was made of the formal and informal costs of ABD in the population of the Basque Country and Navarre (2,750,000 people. Results The cross-sectional study showed that the incidences of ABD caused by stroke and TBI were 61.8 and 12.5 cases per 100,000 per year respectively, while the overall prevalence was 657 cases per 100,000 people. The SF-36 physical and mental component scores were 28.9 and 44.5 respectively. The total economic burden was calculated to be 382.14 million euro per year, distributed between 215.27 and 166.87 of formal and informal burden respectively. The average cost per individual was 21,040 € per year. Conclusions The main conclusion of this study is that ABD has a high impact in both epidemiological and economic terms as well as loss in quality of life. The overall prevalence obtained is equivalent to 0.7% of the total population. The substantial economic burden is distributed nearly evenly between formal and informal costs. Specifically, it was found that the physical dimensions of quality of life are the most severely affected. The prevalence

    Full Text Available Algae, a renewable energy source, has an added advantage of consuming nutrients from wastewater and consequently aiding in wastewater treatment. The algae thus produced can be processed using alternative paths for conversion to fuels. However, due to high moisture content of algae, wet algae processing methods are being encouraged to avoid the dewatering cost and energy. Hydrothermal liquefaction is one such technology that converts the algae into high heating value bio-oil under high temperature and pressure. This bio-oil can be further upgraded to renewable diesel (RD which can be used in diesel powered vehicles without any modifications. The objective of this study is to evaluate the economic viability and to estimate the energy use and greenhouse gas (GHG emissions during life cycle of RD production from algae grown in wastewater using hydrothermal liquefaction. Economic analysis of RD production on commercial scale was performed using engineering process model of RD production plant with processing capacity of 60 Mgal wastewater/day, simulated in SuperPro designer. RD yields for algae were estimated as 10.18 MML/year with unit price of production as $1.75/RD. The GHG emissions during life cycle of RD production were found to be 6.2 times less than those produced for conventional diesel. Sensitivity analysis indicated a potential to reduce ethanol production cost either by using high lipid algae or increasing the plant size. The integrated economic and ecological assessment analyses are helpful in determining long-term sustainability of a product and can be used to drive energy policies in an environmentally sustainable direction.

    Hand, foot and mouth disease (HFMD) is a common illness in China that mainly affects infants and children. The objective of this study is to assess the economic cost and health-related quality of life associated with HFMD in China. A telephone survey of caregivers were conducted in 31 provinces across China. Caregivers of laboratory-confirmed HFMD patients who were registered in the national HFMD enhanced surveillance database during 2012-2013 were invited to participate in the survey. Total costs included direct medical costs (outpatient care, inpatient care and self-medication), direct non-medical costs (transportation, nutrition, accommodation and nursery), and indirect costs for lost income associated with caregiving. Health utility weights elicited using EuroQol EQ-5D-3L and EQ-Visual Analogue Scale (VAS) were used to calculate associated loss in quality adjusted life years (QALYs). The subjects comprised 1136 mild outpatients, 1124 mild inpatients, 1170 severe cases and 61 fatal cases. The mean total costs for mild outpatients, mild inpatients, severe cases and fatal cases were $201 (95%CI $187, $215), $1072 (95%CI $999, $1144), $3051 (95%CI $2905, $3197) and $2819 (95%CI $2068, $3571) respectively. The mean QALY losses per HFMD episode for mild outpatients, mild inpatients and severe cases were 3.6 (95%CI 3.4, 3,9), 6.9 (95%CI 6.4, 7.4) and 13.7 (95%CI 12.9, 14.5) per 1000 persons. Cases who were diagnosed with EV-A71 infection and had longer duration of illness were associated with higher total cost and QALY loss. HFMD poses a high economic and health burden in China. Our results provide economic and health utility data for cost-effectiveness analysis for HFMD vaccination in China.

    Full Text Available This study examined the impact of diet protein and carbohydrate percentages as well as moisture on the immature development, survivorship, and resulting adult longevity and egg production of the black soldier fly, Hermetia illucens (L. (Diptera: Stratiomyidae. Moisture impacted development and corresponding life-history traits more than protein:carbohydrate content; larvae were unable to develop on diets at 40% moisture. Larvae fed diets at 70% moisture developed faster, grew larger, and required less food than those reared on diets at 55% moisture. Larvae reared on the balanced diet (21% protein:21% carbohydrate at 70% moisture developed the fastest on the least amount of food and had the greatest survivorship to the prepupal stage. Adult emergence and longevity were similar across treatments, indicating immature life-history traits were impacted the most. The control (Gainesville house fly diet was superior to the artificial diets for all parameters tested. These differences could indicate that other constituents (e.g., associated microbes serve a role in black soldier fly development. These data are valuable for industrialization of this insect as a “green” technology for recycling organic waste, which can be highly variable, to produce protein for use as feed in the livestock, poultry, and aquaculture industries, as well as for bioenergy production.

    To date, there has been no published comprehensive estimation of costs related to Prader-Willi syndrome (PWS). Our objective was therefore to provide data on the economic burden and health-related quality of life associated with PWS in France in order to raise awareness of the repercussions on individuals suffering from this syndrome and on caregivers as well as on the health and social care systems. A retrospective cross-sectional study was carried out on 51 individuals recruited through the French PWS patient association. Data on their demographic characteristics and resource use were obtained from an online questionnaire, and costs were estimated by a bottom-up approach. The EQ-5D-5L health questionnaire was used to measure the health-related quality of life of individuals suffering from PWS and their caregivers. The average annual cost of PWS was estimated at €58 890 per individual, with direct healthcare accounting for €42 299, direct non-healthcare formal costs €13 865 and direct non-healthcare informal costs €8459. The main contributors to PWS costs were hospitalisations and social services. Indirect costs resulting from loss of productivity in the labour market was €32 542 for adults suffering from PWS. Mean EQ-5D utility scores were 0.4 for individuals with PWS and 0.7 for caregivers. Prader-Willi syndrome represents a major economic burden from a societal perspective and has a significant impact on health-related quality of life both for individuals suffering from PWS and for their caregivers in France. These results underscore the need to develop tailored policies targeted at improving care. Likewise, a larger study collecting a broader range of medical characteristics should be undertaken to achieve more precise estimations. © 2016 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    A consequential life cycle assessment (LCA) is conducted to evaluate the trade-offs between water quality improvements and the incremental climate, resource, and economic costs of implementing green (bioretention basin, green roof, and permeable pavement) versus gray (municipal separate stormwater sewer systems, MS4) alternatives of stormwater infrastructure expansions against a baseline combined sewer system with combined sewer overflows in a typical Northeast US watershed for typical, dry, and wet years. Results show that bioretention basins can achieve water quality improvement goals (e.g., mitigating freshwater eutrophication) for the least climate and economic costs of 61 kg CO2 eq. and $98 per kg P eq. reduction, respectively. MS4 demonstrates the minimum life cycle fossil energy use of 42 kg oil eq. per kg P eq. reduction. When integrated with the expansion in stormwater infrastructure, implementation of advanced wastewater treatment processes can further reduce the impact of stormwater runoff on aquatic environment at a minimal environmental cost (77 kg CO2 eq. per kg P eq. reduction), which provides support and valuable insights for the further development of integrated management of stormwater and wastewater. The consideration of critical model parameters (i.e., precipitation intensity, land imperviousness, and infrastructure life expectancy) highlighted the importance and implications of varying local conditions and infrastructure characteristics on the costs and benefits of stormwater management. Of particular note is that the impact of MS4 on the local aquatic environment is highly dependent on local runoff quality indicating that a combined system of green infrastructure prior to MS4 potentially provides a more cost-effective improvement to local water quality.

    Full Text Available Nitrogen (N fertilizer plays an important role in agricultural systems in terms of food yield. However, N application rates (NARs are often overestimated over the rice (Oryza sativa L. growing season in the Taihu Lake region of China. This is largely because negative externalities are not entirely included when evaluating economically-optimal nitrogen rate (EONR, such as only individual N losses are taken into account, or the inventory flows of reactive N have been limited solely to the farming process when evaluating environmental and economic effects of N fertilizer. This study integrates important material and energy flows resulting from N use into a rice agricultural inventory that constitutes the hub of the life-cycle assessment (LCA method. An economic evaluation is used to determine an environmental and economic NAR for the Taihu Lake region. The analysis reveals that production and exploitation processes consume the largest proportion of resources, accounting for 77.2 % and 22.3 % of total resources, respectively. Regarding environmental impact, global warming creates the highest cost with contributions stemming mostly from fertilizer production and farming processes. Farming process incurs the biggest environmental impact of the three environmental impact categories considered, whereas transportation has a much smaller effect. When taking account of resource consumption and environmental cost, the marginal benefit of 1 kg rice would decrease from 2.4 to only 1.05 yuan. Accordingly, our current EONR has been evaluated at 187 kg N ha−1 for a single rice-growing season. This could enhance profitability, as well as reduce the N losses associated with rice growing.

  6. Synthetic spider silk sustainability verification by techno-economic and life cycle analysis

    Science.gov (United States)

    Edlund, Alan

    Major ampullate spider silk represents a promising biomaterial with diverse commercial potential ranging from textiles to medical devices due to the excellent physical and thermal properties from the protein structure. Recent advancements in synthetic biology have facilitated the development of recombinant spider silk proteins from Escherichia coli (E. coli), alfalfa, and goats. This study specifically investigates the economic feasibility and environmental impact of synthetic spider silk manufacturing. Pilot scale data was used to validate an engineering process model that includes all of the required sub-processing steps for synthetic fiber manufacture: production, harvesting, purification, drying, and spinning. Modeling was constructed modularly to support assessment of alternative protein production methods (alfalfa and goats) as well as alternative down-stream processing technologies. The techno-economic analysis indicates a minimum sale price from pioneer and optimized E. coli plants at 761 kg-1 and 23 kg-1 with greenhouse gas emissions of 572 kg CO2-eq. kg-1 and 55 kg CO2-eq. kg-1, respectively. Spider silk sale price estimates from goat pioneer and optimized results are 730 kg-1 and 54 kg-1, respectively, with pioneer and optimized alfalfa plants are 207 kg-1 and 9.22 kg-1 respectively. Elevated costs and emissions from the pioneer plant can be directly tied to the high material consumption and low protein yield. Decreased production costs associated with the optimized plants include improved protein yield, process optimization, and an Nth plant assumption. Discussion focuses on the commercial potential of spider silk, the production performance requirements for commercialization, and impact of alternative technologies on the sustainability of the system.

  7. Towards real energy economics: Energy policy driven by life-cycle carbon emission

    2010-01-01

    Alternative energy technologies (AETs) have emerged as a solution to the challenge of simultaneously meeting rising electricity demand while reducing carbon emissions. However, as all AETs are responsible for some greenhouse gas (GHG) emissions during their construction, carbon emission 'Ponzi Schemes' are currently possible, wherein an AET industry expands so quickly that the GHG emissions prevented by a given technology are negated to fabricate the next wave of AET deployment. In an era where there are physical constraints to the GHG emissions the climate can sustain in the short term this may be unacceptable. To provide quantitative solutions to this problem, this paper introduces the concept of dynamic carbon life-cycle analyses, which generate carbon-neutral growth rates. These conceptual tools become increasingly important as the world transitions to a low-carbon economy by reducing fossil fuel combustion. In choosing this method of evaluation it was possible to focus uniquely on reducing carbon emissions to the recommended levels by outlining the most carbon-effective approach to climate change mitigation. The results of using dynamic life-cycle analysis provide policy makers with standardized information that will drive the optimization of electricity generation for effective climate change mitigation.

    End of life care may have elements of value that go beyond health. A generic measure of the benefits of end of life care could be helpful to decision makers. Such a measure, based on the capability approach, has recently been developed: the ICECAP Supportive Care Measure. This paper reports the first valuation exercise for that measure, with data from 6020 individuals collected from an on-line general population panel during June 2013. Individuals were asked to complete a stated choice experiment that combined best-worst scaling and a standard discrete choice experiment. Analysis of the best-worst data used limited dependent variable models within the random utility framework including the multinomial logit models and latent class choice model analysis. Exploratory steps were taken to determine the similarity of the best-worst and DCE data before formal testing and pooling of the two data sources. Combined data were analysed in a heteroscedastic conditional logit model adjusting for continuous scale. Two sets of tariffs were generated, one from the best-worst data capturing only main effects, and a second from the pooled data allowing for two-way interactions. Either tariff could be used in economic evaluation of interventions at the end of life, although there are advantages and disadvantages with each. This extensive valuation exercise for the ICECAP Supportive Care Measure, with a large number of members of the general public, could be complemented in the future with best-worst scaling studies amongst those experiencing the end of life.

    Petroleum fuels are predominantly transported domestically by pipelines, whereas biofuels are almost exclusively transported by rail, barge, and truck. As biofuel production increases, new pipelines may become economically attractive. Location-specific variables impacting pipeline viability include construction costs, availability and costs of alternative transportation modes, electricity prices and emissions (if priced), throughput, and subsurface temperature. When transporting alcohol or diesel-like fuels, pipelines have a lower direct energy intensity than rail, barge, and trucks if fluid velocity is under 1 m/s for 4-inch diameter pipelines and 2 m/s for 8-inch or larger pipelines. Across multiple hypothetical state-specific scenarios, profit-maximizing design velocities range from 1.2 to 1.9 m/s. In costs and GHG emissions, optimized pipelines outperform trucks in each state and rail and barge in most states, if projected throughput exceeds four billion liters/year. If emissions are priced, optimum design diameters typically increase to reduce pumping energy demands, increasing the cost-effectiveness of pipeline projects. Copyright © 2013 Elsevier Ltd.

    Addressing the multitude of challenges in marine policy requires an integrated approach that considers the multitude of drivers, pressures, and interests, from several disciplinary angles. Scenarios are needed to harmonise the analyses of different components of the marine system, and to deal with the uncertainty and complexity of the societal and biogeophysical dynamics in the system. This study considers a set of socio-economic scenarios to (1) explore possible futures in relation to marine invasive species, outbreak forming species, and gradual changes in species distribution and productivity; and (2) harmonise the projection modelling performed within associated studies. The exercise demonstrates that developing interdisciplinary scenarios as developed in this study is particularly complicated due to (1) the wide variety in endogeneity or exogeneity of variables in the different analyses involved; (2) the dual role of policy decisions as variables in a scenario or decisions to be evaluated and compared to other decisions; and (3) the substantial difference in time scale between societal and physical drivers.

    Human newborns are vulnerable to infectious diseases that account for majority of the morbidity and mortality, particularly in first year of life. Vaccines have become the most effective public health intervention strategy to curtail the prevalence of these infectious diseases. Although vaccines against a number of diseases exist, there are no vaccines against many other diseases that commonly affect children. The adequate assessment of immune responses to vaccines is an important step in the development of vaccines. However, a number of biological and "non-medical" socio-economic and ethical factors could influence either the administration and/or evaluation of vaccines in infants. Recognition and understanding of these determinants are crucial in planning interventions and for logical interpretations of results. Copyright © 2012 Elsevier Ltd. All rights reserved.

  16. Sustainability Efficiency Factor: Measuring Sustainability in Advanced Energy Systems through Exergy, Exergoeconomic, Life Cycle, and Economic Analyses

    Boldon, Lauren

    The Encyclopedia of Life Support Systems defines sustainability or industrial ecology as "the wise use of resources through critical attention to policy, social, economic, technological, and ecological management of natural and human engineered capital so as to promote innovations that assure a higher degree of human needs fulfilment, or life support, across all regions of the world, while at the same time ensuring intergenerational equity" (Encyclopedia of Life Support Systems 1998). Developing and integrating sustainable energy systems to meet growing energy demands is a daunting task. Although the technology to utilize renewable energies is well understood, there are limited locations which are ideally suited for renewable energy development. Even in areas with significant wind or solar availability, backup or redundant energy supplies are still required during periods of low renewable generation. This is precisely why it would be difficult to make the switch directly from fossil fuel to renewable energy generation. A transition period in which a base-load generation supports renewables is required, and nuclear energy suits this need well with its limited life cycle emissions and fuel price stability. Sustainability is achieved by balancing environmental, economic, and social considerations, such that energy is produced without detriment to future generations through loss of resources, harm to the environment, etcetera. In essence, the goal is to provide future generations with the same opportunities to produce energy that the current generation has. This research explores sustainability metrics as they apply to a small modular reactor (SMR)-hydrogen production plant coupled with wind energy and storage technologies to develop a new quantitative sustainability metric, the Sustainability Efficiency Factor (SEF), for comparison of energy systems. The SEF incorporates the three fundamental aspects of sustainability and provides SMR or nuclear hybrid energy system

    Full Text Available The present contribution - starting from the experience of the EATGA Workshop 2011 that took place in Palermo and that had as its theme “Intersubjective bonds in the globalized economy” - invites to reflect on the quality of the life of relationship and intersubjective connectedness in social contemporary world. One of the characterizing cultural phenomena influencing contemporary reality is made up by the dominant and pervasive presence of logic and language of financial markets in policies and activities that organize and articulate daily life. Theoretical hypothesis driving our research is that the structures of subjectivity, the meaning and the way of being in a relationship are characteristics (cultural themes that emerge within a defined cultural and historical system. In such a theoretical perspective, cultural themes are incorporated or interiorized by men belonging a shared cultural system and so became elements of the shared subjectivity and of the meanings given to intersubjective exchanges and bonds. From the workshop experience some meanings emerge concerning the role of economical-financial system in promoting codes and symbols that define the shape and the sense of relationship. The cultural codes of the market have gone out from the economic circle in which they were born and they are offered as organizers of affections and relationships. This is an evidence for the critical actual historical moment, in which the values and the cultural codes organized on the trust, on the reciprocity, on the common share and participation seems to be interdicted.Keywords: Transcultural Group-Analysis, Intersubjective Relationship, Cultural Models of the Exchange

    Insight into the occurrence of and the association between certain socio-economic variables and life-style characteristics is necessary for preventive nutrition and health policy. The prevalence of and the interdependencies among these variables were examined in 1930 men and 2204 women aged 19 to 85 who participated in the Dutch National Food Consumption Survey 1987-1988. Dietary data were based on a two-day record. The associations among discrete variables were analysed using log-linear models. Analysis of covariance was used to explore the effects of the aggregate socio-economic status (SES) on dietary intake and anthropometry, whereas differences in food intake and SES were assessed by the non-parametric test of Kruskal and Wallis. In comparison to subjects with a high SES in people with a low SES a higher proportion of smokers (48 vs 32 per cent) was observed, a higher prevalence of obesity (39 vs 28 per cent), a higher percentage of heavy coffee drinkers (greater than six cups per day, 23 vs 17 per cent), and more subjects who skipped breakfast (19 vs 11 per cent). In the highest SES class more subjects used nutritional supplements (18 vs 11 per cent), more subjects followed a dietary rule (five vs two per cent), such as a vegetarian diet, and a higher proportion used more than three alcoholic drinks per day (19 vs 15 per cent). A higher SES was associated with a lower fat intake, but the differences (expressed as per cent of energy intake) were rather small and even absent among women when the contribution of alcohol to energy was not taken into account. In general, dietary intake among subjects in higher SES groups tended to be closer to dietary recommendations. The results indicate that a lower SES is accompanied by a higher prevalence of several indicators of an unhealthy life-style.

    In this study the energy and economic flows and greenhouse gas (GHG) emissions of olive oil production in Iran were investigated in terms of a life cycle assessment with considering four main stages of agricultural olive production, olive transportation, olive oil extraction and its oil transportation to the customer centers. Data was collected from 150 olive growers in Guilan province of Iran. Results revealed that the total energy consumption through the olive oil life cycle was 20 344 MJ ha −1 while the mass-based allocation method results indicated that the total energy consumption was 8035 MJ ha −1 . The total energy output was estimated as 23 568 MJ ha −1 . The total GHG emissions was estimated to 1333 kg ha −1 (CO 2 eq) while the mass-based allocation method results indicated that the total GHG emissions was 525 kg ha −1 (CO 2 eq). The agricultural production stage ranked the first in GHG emissions among the four stages with the share of 93.81% of total GHG emissions. Results of econometric model estimation revealed that the impact of human labor, farmyard manure and electricity on olive oil yield and the impact of electricity and chemical fertilizers on GHG emissions were significantly positive. - Highlights: • Energy and economic flows and GHG emissions of olive oil production in Iran were investigated. • The total energy consumption of olive oil production was calculated as 20 344 MJ ha −1 . • The mass-based allocation showed the energy consumption of olive oil production was 8035 MJ ha −1 . • The total GHG emissions of olive oil production was 1333 kg ha −1 (CO 2 eq). • The mass-based allocation showed the total GHG emissions of olive oil production was 525 kg ha −1 (CO 2 eq)

    To evaluate work productivity and its economic burden in SSc patients. Consecutive SSc patients enrolled in the Australian Scleroderma Cohort Study were mailed questionnaires assessing employment (Workers' Productivity and Activity Impairment Questionnaire and a custom-made questionnaire) and health-related quality of life (HRQoL) (36-item Short Form Health Survey and Patient-Reported Outcomes Measurement Information System 29). Linear regression methods were used to determine factors associated with work productivity. Among 476 patients submitting responses, 55.2% productivity while at work (presenteeism) accounted for 22% of their working week. Annual costs per patient as a consequence of unemployment and reduced productivity equated to a total of AUD$67 595.40. Factors independently associated with reduced work productivity were presence of synovitis and sicca symptoms, while tertiary education protected against work impairment. Patients with low HRQoL scores also had low work productivity. SSc is associated with considerable unemployment and reduced productivity, which in turn is associated with a substantial economic burden and poor HRQoL. Raising awareness and identifying modifiable factors are possible ways of reducing this burden. © The Author 2017.

    2016-01-01

    Feed-in tariffs and Renewable Portfolio Standards (RPS) are among the most prominent policies to address anthropogenic influence on climate change. Implementation of RPS favorably affects renewable energy supply and rural development while reducing the land available for meeting demand for food and feed resulting from global population growth. Even in the vast Great Plains of the United States, land requirements are primary considerations between increasing renewable energy capacity and food and feed production. This study applied life cycle assessment (LCA) and project economics to estimate and compare the land intensity and profitability of anaerobic digestion and wind energy projects in the Great Plains. The results show that significantly more energy and revenue can be generated per hectare of land using wind versus anaerobic digestion. Economically, the benefit-to-cost ratios of wind farms were almost twice as favorable as anaerobic digester facilities. Wind farms have consistent benefit-to-cost ratios of 2.15 while the anaerobic digester facilities benefit to cost ratios range from 1.2 to 1.25. Legislature changes to RPS could incentivize increasing the number of anaerobic digesters while also assisting in reversing the current trend of diminishing dairy farms while reducing climate change risks and creating new economic opportunities for renewable energy. - Highlights: • Wind 1160 GW h to 28,706 GW h between 2 and 129 ha. • AD 29 GW h to 393 GW h between 14 and 105 ha. • More energy and revenue can be generated per hectare using wind energy AD. • An ideal solution for dairy farmers may be an integrated solution • State legislature changes to RPS could incentivize increasing AD facilities.

    The goal of this study was to integrate a crop model, DNDC (DeNitrification-DeComposition), with life cycle assessment (LCA) and economic analysis models using a GIS-based integrated platform, ENVISION. The integrated model enables LCA practitioners to conduct integrated economic analysis and LCA on a regional scale while capturing the variability of soil emissions due to variation in regional factors during production of crops and biofuel feedstocks. In order to evaluate the integrated model, the corn-soybean cropping system in Eagle Creek Watershed, Indiana was studied and the integrated model was used to first model the soil emissions and then conduct the LCA as well as economic analysis. The results showed that the variation in soil emissions due to variation in weather is high causing some locations to be carbon sink in some years and source of CO 2 in other years. In order to test the model under different scenarios, two tillage scenarios were defined: 1) conventional tillage (CT) and 2) no tillage (NT) and analyzed with the model. The overall GHG emissions for the corn-soybean cropping system was simulated and results showed that the NT scenario resulted in lower soil GHG emissions compared to CT scenario. Moreover, global warming potential (GWP) of corn ethanol from well to pump varied between 57 and 92gCO 2 -eq./MJ while GWP under the NT system was lower than that of the CT system. The cost break-even point was calculated as $3612.5/ha in a two year corn-soybean cropping system and the results showed that under low and medium prices for corn and soybean most of the farms did not meet the break-even point.

    We assessed associations between discrimination and health-related quality of life among black and white men and women in the United States. We examined data from the National Health Measurement Study, a nationally representative sample of 3,648 adults aged 35-89 in the non-institutionalized US population. These data include self-reported lifetime and everyday discrimination as well as several health utility indexes (EQ-5D, HUI3, and SF-6D). Multiple regression was used to compute mean health utility scores adjusted for age, income, education, and chronic diseases for each race-by-gender subgroup. Black men and women reported more discrimination than white men and women. Health utility tended to be worse as reported discrimination increased. With a few exceptions, differences between mean health utility scores in the lowest and highest discrimination groups exceeded the 0.03 difference generally considered to be a clinically significant difference. Persons who experienced discrimination tended to score lower on health utility measures. The study also revealed a complex relationship between experiences of discrimination and race and gender. Because of these differential social and demographic relationships caution is urged when interpreting self-rated health measures in research, clinical, and policy settings.

  5. The Influence of Major Life Events on Economic Attitudes in a World of Gene-Environment Interplay.

    Hatemi, Peter K

    2013-10-01

    The role of "genes" on political attitudes has gained attention across disciplines. However, person-specific experiences have yet to be incorporated into models that consider genetic influences. Relying on a gene-environment interplay approach, this study explicates how life-events, such as losing one's job or suffering a financial loss, influence economic policy attitudes. The results indicate genetic and environmental variance on support for unions, immigration, capitalism, socialism and property tax is moderated by financial risks. Changes in the magnitude of genetic influences, however, are temporary. After two years, the phenotypic effects of the life events remain on most attitudes, but changes in the sources of individual differences do not. Univariate twin models that estimate the independent contributions of genes and environment on the variation of attitudes appear to provide robust baseline indicators of sources of individual differences. These estimates, however, are not event or day specific. In this way, genetic influences add stability, while environment cues change, and this process is continually updated.

    A novel framework, integrating dynamic simulation (DS), life cycle assessment (LCA) and techno-economic assessment (TEA) of a bioelectrochemical system (BES), has been developed to study for the first time wastewater treatment by removal of chemical oxygen demand (COD) by oxidation in anode and thereby harvesting electron and proton for carbon dioxide reduction reaction or reuse to produce products in cathode. Increases in initial COD and applied potential increase COD removal and production (in this case formic acid) rates. DS correlations are used in LCA and TEA for holistic performance analyses. The cost of production of HCOOH is €0.015-0.005 g -1 for its production rate of 0.094-0.26 kg yr -1 and a COD removal rate of 0.038-0.106 kg yr -1 . The life cycle (LC) benefits by avoiding fossil-based formic acid production (93%) and electricity for wastewater treatment (12%) outweigh LC costs of operation and assemblage of BES (-5%), giving a net 61MJkg -1 HCOOH saving.

    Moving bed biofilm reactor (MBBR) is a highly effective biological treatment process applied to treat both urban and industrial wastewaters in developing countries. The present study investigated the technical performance of ten full-scale MBBR systems located across India. The biochemical oxygen demand, chemical oxygen demand, total suspended solid, pathogens, and nutrient removal efficiencies were low as compared to the values claimed in literature. Plant 1 was considered for evaluation of environmental impacts using life cycle assessment approach. CML 2 baseline 2000 methodology was adopted, in which 11 impact categories were considered. The life cycle impact assessment results revealed that the main environmental hot spot of this system was energy consumption. Additionally, two scenarios were compared: scenario 1 (direct discharge of treated effluent, i.e., no reuse) and scenario 2 (effluent reuse and tap water replacement). The results showed that scenario 2 significantly reduce the environmental impact in all the categories ultimately decreasing the environmental burden. Moreover, significant economic and environmental benefits can be obtained in scenario 2 by replacing the freshwater demand for non-potable uses. To enhance the performance of wastewater treatment plant (WWTP), there is a need to optimize energy consumption and increase wastewater collection efficiency to maximize the operating capacity of plant and minimize overall environmental footprint. It was concluded that MBBR can be a good alternative for upgrading and optimizing existing municipal wastewater treatment plants with appropriate tertiary treatment. Graphical abstract ᅟ.

  8. The role of underground construction for the mobility, quality of life and economic and social sustainability of urban regions

    Manuel Luís Tender

    Full Text Available Abstract Tunnelling has been used for several purposes for thousands of years. In the coming years the world's population will increase in the urban areas. So, the urban centres will have to adapt, in order to guarantee that their future population will have the necessary and sustainable growth. Due to the constraints for surface construction, also connected to environmental issues, this population growth will imply a greater use of the underground. With this optimal growth, the population of the cities will have better mobility, quality of life, and economic and social sustainability. In a first phase, this report will present a historic approach to tunnelling and its foreseeable future. Afterwards, we will present some considerations on the three factors which tunnelling impacts: mobility, quality of life and social sustainability. As a case study, we will analyse the 2nd phase of the construction of the Marão Tunnel (TDM - the longest ever built in the Iberian Peninsula- and describe the options made regarding each of those factors. In this case study, the options implemented made it possible to successfully execute the works. For the industry, this work is important because it describes a successful management of the aspects under analysis.

    EQOFIX is a medicoeconomic study that analyzed the health-related quality of life (HRQoL) and costs of care of the moderate and severe forms of hemophilia B, treated on demand or by prophylaxis with either plasma-derived Factor IX (pdFIX) or recombinant FIX (rFIX). The primary objectives were evaluations of the impact of hemophilia B on HRQoL and of the costs associated with its management. The secondary objectives were evaluations of the clinical efficacy and costs of care of pdFIX and rFIX. In this observational study we included and followed for 1 year severe and moderate hemophilia B patients without inhibitor. HRQoL was evaluated through generic and disease-specific questionnaires. Information on the health resources consumed was collected every 3 months. The EQOFIX cohort was composed of 155 patients, including 51 children and 104 adults, with 114 having severe disease and 41 having moderate disease. The regimens were prophylactic for 61 and on demand for 94. Altogether, 78 were treated with rFIX and 77 with pdFIX. There was no difference in the QoL between the pdFIX and rFIX treatments. The extra cost of prophylaxis was €22,605 per bleeding event prevented. The consumption of FIX was 1.4-fold higher for the patients treated with rFIX than for the patients treated with pdFIX. Our findings in a cohort composed of 25% of the French population of moderate and severe hemophilia B patients show, with similar clinical and HRQoL results, that treatment with rFIX is more expensive than treatment with pdFIX. © 2015 The Authors.

    Full Text Available This article examines the relative importance of race and socioeconomic status (SES in determining whether Black and White teenagers report having ever been pregnant. Data gathered from 1999 to 2006 by the National Center for Health Statistics of the Center for Disease Control and Prevention included 1,580 Black and White females aged 15 to 19 years. Results supported the effects of race and SES, with SES having the stronger effect. However, the effects of race and SES differ when controlling for the state of the economy. No difference between Blacks and Whites was found during better economic times. During 2003-2004, the period of greatest economic stress, race was determined to be the only predictor of teenage pregnancy. In particular, during 2005-2006, the reduction in pregnancy rates for Black minors (15-17 fell below those for White minors within their respective SES categories. Policy implications are discussed in light of these findings.

    Full Text Available To speak and understand a language means - among many other things - knowing the words of that language. The average speaker knows, hears, understands and uses thousands of words daily. But does he use them appropriately? That is why this paper is about words and meanings. More specifically, it deals with the internal structure of complex words, i.e. derivatives. The purpose of the paper is to enable students and potentially other individuals dealing with English language on business basis to engage in their own analyses of some aspects of the language, namely the family tree of the word economy. After having read the paper, the reader should be familiar with the necessary knowledge regarding differences between meanings, misuse and actual sense of words deriving from economy, be able to systematically analyze data and relate his own findings on theoretical language problems. English is used by hundreds of millions speakers and still there is always need for improving our knowledge continuously. Knowing and speaking approximate English may not be enough at an advanced level as in the case of students who prepare themselves for careers that involve proficient communication in a foreign language on specific business issues. This is where the idea of such a paper appeared: students of the Faculty of Economic Sciences talk about economy and all the other terms deriving from it, with approximate knowledge of their meaning, without even being aware that some ‘minor' suffixes like –ic, -ical, -ics etc. really matter and do make a difference. Consequently, we started our teaching of Business English lecture in September 2012 with a working sheet based on the terms economic/ economical/ economics/ economy to assess students' awareness of these terms. The result was not a surprise as more than 90% misused economical instead of economic. That seemed a perfect introduction for students in economics. From that moment on, the building of their specific

    Economic recession affects quality of life by increasing rates of mental disorders in particular. Social support can be an important protective factor. To estimate the impact of being personally affected by an economic crisis on health-related quality of life (HRQoL), taking into account the possible buffering effect of perceived social support. Data from the first wave (March 2012 to November 2012) of the 'Social Support and Quality of Life Study', a longitudinal study carried out in a primary health care centre in a deprived neighbourhood of Barcelona, Spain. A total of 143 participants were assessed using the 12-item Short-Form Health Survey, the List of Threatening Experiences and the Duke Social Support scales. The effect of economic crisis on mental and physical HRQoL was assessed using ordinary least squares regression models to test the interaction between social support and having experienced an economic crisis. There was no statistical association between having suffered an economic crisis and physical HRQoL. The interaction between social support and economic crisis was also tested without finding any statistical association. An interaction was detected between social support and economic crisis in relation to mental HRQoL; those who had low levels of social support and had also experienced an economic crisis had the lowest levels of mental HRQoL. Social support constitutes a safety net that offers protection against the adverse effect of economic recessions on mental health. Primary care professionals are in a key position to promote social activities and to strengthen social networks in the community. © British Journal of General Practice 2015.

    Feeling of meaning in life is extremely crucial factor of mental health. The lack of it can result in various disorders. Many authors, especially those connected with current of humanistic psychology underline the teenagers' life sense. The aim of the paper was to examine the level of satisfaction with life, the frequency of psychosomatic complaints by junior high school students as well as the estimation of economical status of family and the analysis of meaning in life with above mentioned factors. The research was carried out in 2015 at 70 schools from all over the country, in group of 3695 lower secondary school students of I-III classes at the age of 13-17 (M=14,9; SD=0,87). The analysis connected with meaning in life using the shorten version of Purpose in Life Test (PIL) as well as analysis of life satisfaction using Cantril scale were taken up. What is more, the subjective physical complaints using single-factor shorten scale and economic status of family with the usage of material resources FAS scale (Family Affluence Scale) were examined. The statistical analysis included a one-way analysis of variance (ANOVA), t-student test post-hoc test as well as multivariate logistic regression model. The average level of meaning in life among the examined students was 24,7 points (the summary scale 0-36 points), the boys achieved higher score than girls. The students satisfied with life (t=28,0; plife than students who were dissatisfied with their life, often or fairly suffer from health complaints and live in families of at most average level of affluence. The meaning in life is positively connected with satisfaction with life, lack of subjective complaints and family affluence. Because there is a lack of analysis linked with school teenagers' meaning in life in Polish literature, another research involved not only shorten but also full version of this tool should be conducted.

Irrigation was done using a line source sprinkler system. It was used a randomized complete block design for the irrigation variable, with the factor nitrogen, a split plot on irrigation and five replications. The eight irrigation levels applied were: 1.3, 107.1, 135.7, 295.9, 330.3, 469.7, 544.3 and 546.1mm. The six nitrogen doses were: 0.00, 0.02, 0.04, 0.08, 0.16, and 0.32Mg/ha. The rude protein content for the maximum economical dry matter yield was 17.6%. Considering input costs and output prices of black oat forage, it was calculated the maximum economical yield of 3.87Mg/ha of dry matter for 280mm of irrigation depth and for 0.094Mg/ha nitrogen level, which allowed a profit of R$147.32 per ha. The marginal rate of substitution was found to be 0.44mm water per 1x10-3Mg/ha of nitrogen. Maximum dry matter yield 4.22Mg/ha was verified for the 336mm irrigation depth and for 0.22Mg/ha nitrogen dose.

    Highlights: • CH 4 production from Power to Gas and upgrading technologies have been assessed. • Both environmental and economic assessments of have been done. • We perform sensitivity analyses to identify key parameters. - Abstract: To decrease the use of fossil fuels and face the energetic demand, the integration of renewable energy is a necessary step. Part of this renewable energy can be supplied by the production of electricity from photovoltaic panels and windfarms. The massive use of these intermittent energies will lead to overproduction periods, and there is consequently a need to convert this surplus of electricity into a storable form of energy. Power-to-gas (PtG) technology consists in using electricity to convert water into hydrogen by electrolysis, and then to synthetize methane from carbon dioxide and hydrogen. Techno-economic and Life Cycle Assessment of methane production via the combination of anaerobic digestion and PtG technology have been applied to sewage sludge valorization. Process studies and equipment design have been addressed considering already available technologies. Sensitivity analyses have been done on biogas upgrading technologies, electricity prices, annual operation time and composition of the electricity mix with also a comparison between PtG and direct injection. It appears that the more the electricity is expensive, the longer the operation time of the methanation process must be to be competitive with injection of methane from biogas. Reduction of electricity consumption of the electrolysis step decreases production costs. Even if the current context does not feature adapted conditions to ensure an economically viable chain, the evolution of the energetic context in the next few years as well as the expected technological improvements will contribute to overall cost reduction. From an environmental point of view, continuous PtG generates more greenhouse gases than direct injection, but intermittent operation with use of

    Black, green, and red abalones (Haliotis cracherodii, H. fulgens, and H. rufescens, respectivley) are of commercial and ecological importance and are distributed widely along the California coast. The abalones are morphologically similar; species are distinguished by particular shell sculpture, color, and body characteristics. Their latitudinal and bathymetric distribution is stratified and most closely related to temperature. Small juveniles eat mainly microflora; adults eat primarily drift macro-algae, preferring specific brown or red algae, when available. Spawning occurs during summer; gonad ripening depends on food quality and quantity and water temperature. Larvae are lecithotrophic and remain planktonic for periods of 5 to 14 days after hatching; settling is substrate specific. Postlarvae and adults require hard substrate for attachment. Juveniles are cryptic, adults usually more exposed. Growth rates are similar, although maximum size varies with species. Increases in shell length and body weight correlate positively with food abundance and temperature. Below depths of 6 m, sea urchins are major competitors for food and space. Predation by invertebrates is low. Decreased abalone production from central California is associated with range expansion and increased predation by sea otters, the major source of abalone mortality. General declines in California landings are due to mortality from improper picking and replacement, habitat degradation, and perhaps overfishing. Commercial and sport diving efforts have increased sharply, whereas annual landings of abalones declined from 1965 to 1982.

    Full Text Available The article describes the results of an integral assessment of the regional social, environmental and economic systems (SEES and the quality of life (QOL in the regions of Russia’s Northwestern Federal District (NWFD. This work aims at giving an integrated assessment of SEES in the Arkhangelsk and Murmansk regions in comparison to the Moscow region. The authors examine the QOL in 10 NWFD regions, including the Baltic ones. The significance of the research work lies in an integrated and comprehensive assessment of the regional SEES and QOL in 2006, 2009, 2012, and 2013 in view of the effect of priorities within and between groups of assessment parameters. Another important result is the identification of ‘stability limits’, when regions retain their QOL whereas their regional environmental characteristics change. The proposed methodology is based on multi-criteria and integrated approaches, the aggregate index method, and the parameter analysis and synthesis. The assessment of SEES and QOL was performed for five classes (from ‘1 — high’ to ‘5 — poor’ based on calculating statistics for 3—6 groups of assessment criteria at two levels of convolution. The analysis of the data obtained shows an upward trend in QOL in the regions. The authors suggest assessing stability of SEES on the basis of critical values of aggregate indices, at which a given SEES maintain its characteristics and regime properties within a certain QOL class.

    Our goal was to provide data on the economic burden and health-related quality of life (HRQOL) of patients with cystic fibrosis (CF) and their caregivers in Europe. A cross-sectional study was carried out on adults and children with CF in eight European countries. Patients completed an anonymous questionnaire regarding their socio-demographic characteristics, use of healthcare services and presence of a caregiver. Costs were calculated with a bottom-up approach using unit costs from each participating country, and HRQOL was assessed using EQ-5D. The principal caregiver also answered a questionnaire on their characteristics, HRQOL and burden. A total of 905 patients with CF was included (399 adults and 506 children). The total average annual cost per patient varied from €21,144 in Bulgaria to €53,256 in Germany. Adults had higher direct healthcare costs than children, but children had much higher informal care costs (P costs increased with patients' level of dependence. In adults, mean utility fell between 0.640 and 0.870, and the visual analogue scale ranged from 46.0 to 69.7. There was no difference in caregiver HRQOL regardless of whether they cared for an adult or a child. However, caregivers who looked after a child had a significantly higher burden (P = 0.0013). Our study highlights the burden of CF in terms of costs and decreased HRQOL for both patients and their caregivers throughout Europe.

    Edible insects are part of the diets of a significant proportion of rural populations in the tropics especially Africa and Asia, and their use as source of key nutrients for better nutrition is re-emerging. Indigenously, elemental methods are used to process the insects before they are consumed or sold in retail outlets. In recent years, better knowledge of processing, packaging and storage has become necessary because of commercialisation needs. A common processing approach involves drying after a brief heat-treatment step, and then milling into a powdered product which is sold to manufacturers or consumers as ingredient for processing final products. The hydration properties of dried powders of edible house cricket and black soldier fly larvae (BSFL) were studied with the aim of predicting shelf-life stability under typical packaging and storage temperatures experienced in the tropics. Moisture adsorption isotherms were determined gravimetrically at 25, 30 and 35 °C, over 0.11-0.97 water activity (a W ) range, and the data fitted to various models. Sorption isotherms were of type II according to Brunauer classification indicating monolayer-multilayer sorption behaviour. Cricket powder exhibited higher hydration capacity, and a W of this product was less sensitive to temperature variation as compared to BSFL powder. In the two products, water exhibited transitions from bound- to free- state at ~5 g/100 g moisture content. Based on Heiss-Eichner model, a shelf-life of 7 months at 25 °C can be achieved if the cricket and BSFL powders are dried to ca. 5 g/100 g moisture content and packaged in 80 μm thick polyethylene films. At 35 °C the shelf-life of the cricket product is shortened three- to four-fold whereas the BSFL powder is unable to store. Copyright © 2018 Elsevier Ltd. All rights reserved.

    The aim of the study was to determine the effects of various petroleum-derived substances, namely petrol, diesel fuel and spent engine oil, on life history traits and population dynamics of the black bean aphid Aphis fabae Scop. and on growth and chemical composition of its host plant Vicia faba L. Each substance was tested separately, using two concentrations (9 g kg -1 and 18 g kg -1 ). The experiment was conducted in four replications (four pots with five plants in each pot per treatment). Plants were cultivated in both control and contaminated soils. After six weeks from soil contamination and five weeks from sowing the seeds, observations of the effect of petroleum-derived substances on traits of three successive generations of aphids were conducted. Aphids were inoculated separately on leaves using cylindrical cages hermetically closed on both sides. Contamination of aphid occurred through its host plant. Results showed that all tested substances adversely affected A. fabae life history traits and population dynamics: extension of the prereproductive period, reduction of fecundity and life span, reduction of the population intrinsic growth rate. In broad bean, leaf, roots, and shoot growth was also impaired in most conditions, whereas nutrient and heavy metal content varied according to substances, their concentration, as well as plant part analysed. Results indicate that soil contamination with petroleum-derived substances entails far-reaching changes not only in organisms directly exposed to these pollutants (plants), but also indirectly in herbivores (aphids) and consequently provides information about potential negative effects on further links of the food chain, i.e., for predators and parasitoids.

    Full Text Available Abstract Background Cost-of-illness analysis is the main method of providing an overall vision of the economic impact of a disease. Such studies have been used to set priorities for healthcare policies and inform resource allocation. The aim of this study was to determine the economic burden and health-related quality of life (HRQOL in the first, second and third years after surviving a stroke in the Canary Islands, Spain. Methods Cross-sectional, retrospective study of 448 patients with stroke based on ICD 9 discharge codes, who received outpatient care at five hospitals. The study was approved by the Research Ethics Committee of Nuestra Señora de la Candelaria University Hospital. Data on demographic characteristics, health resource utilization, informal care, labor productivity losses and HRQOL were collected from the hospital admissions databases and questionnaires completed by stroke patients or their caregivers. Labor productivity losses were calculated from physical units and converted into monetary units with a human capital-based method. HRQOL was measured with the EuroQol EQ-5D questionnaire. Healthcare costs, productivity losses and informal care costs were analyzed with log-normal, probit and ordered probit multivariate models. Results The average cost for each stroke survivor was €17 618 in the first, €14 453 in the second and €12 924 in the third year after the stroke; the reference year for unit prices was 2004. The largest expenditures in the first year were informal care and hospitalizations; in the second and third years the main costs were for informal care, productivity losses and medication. Mean EQ-5D index scores for stroke survivors were 0.50 for the first, 0.47 for the second and 0.46 for the third year, and mean EQ-5D visual analog scale scores were 56, 52 and 55, respectively. Conclusions The main strengths of this study lie in our bottom-up-approach to costing, and in the evaluation of stroke survivors from a

    Ecological and evolutionary model organisms have provided extensive insight into the ecological triggers, adaptive benefits, and evolution of life-history driven developmental plasticity. Despite this, we still have a poor understanding of the underlying genetic changes that occur during shifts towards different developmental trajectories. The goal of this study is to determine whether we can identify underlying gene expression patterns that can describe the different life-history trajectories individuals follow in response to social cues of competition. To do this, we use the Australian black field cricket (Teleogryllus commodus), a species with sex-specific developmental trajectories moderated by the density and quality of calls heard during immaturity. In this study, we manipulated the social information males and females could hear by rearing individuals in either calling or silent treatments. We next used RNA-Seq to develop a reference transcriptome to study changes in brain gene expression at two points prior to sexual maturation. We show accelerated development in both sexes when exposed to calling; changes were also seen in growth, lifespan, and reproductive effort. Functional relationships between genes and phenotypes were apparent from ontological enrichment analysis. We demonstrate that increased investment towards traits such as growth and reproductive effort were often associated with the expression of a greater number of genes with similar effect, thus providing a suite of candidate genes for future research in this and other invertebrate organisms. Our results provide interesting insight into the genomic underpinnings of developmental plasticity and highlight the potential of a genomic exploration of other evolutionary theories such as condition dependence and sex-specific developmental strategies.

    Full Text Available The aim of this study was to evaluate the effect of gelatin coating incorporated with Aloe vera gel (50,100% and green and black tea extracts (5,10% on physicochemical, microbial, and sensorial properties of fresh-cut oranges at 4°C for 17 days. Significant differences in terms of quality parameters were observed between the control and coated fresh-cut oranges. The highest variation of quality parameters was observed in control, while the least variations were observed in coated slices with 100% Aloe vera and 10% green tea extract. The weight loss was increased with time, but the coating treatment especially with 100% Aloe vera had significant effect on the prevention of weight loss. Also, Aloe vera coated samples obtained the highest score in sensory evaluation. Coating with gelatin incorporated with Aloe vera and green tea extracts successfully retarded the microbial growth and therefore extended the shelf life of fresh-cut oranges during cold storage.

  18. Ecological economics and economic growth.

    Victor, Peter A

    Boulding's 1966 paper on the economics of spaceship Earth established the framework for ecological economics and an understanding of economic growth. In ecological economics, economies are conceptualized as open subsystems of the closed biosphere and are subject to biophysical laws and constraints. Economic growth measured as an increase in real gross domestic product (GDP) has generally been associated with increases in the use of energy and materials and the generation of wastes. Scale, composition, and technology are the proximate determinants of environmental impacts. They are often reduced to two: scale (GDP) and intensity (impact per unit GDP). New work described in this paper defines "green" growth as intensity that declines faster than scale increases. Similarly, "brown" growth occurs when intensity declines more slowly than increases in scale, and "black" growth happens when both scale and intensity increase. These concepts are then related to the environmental Kuznets curve, which can be understood as a transition from brown to green growth. Ecological economics provides a macroperspective on economic growth. It offers broad policy principles, and it challenges the primacy of economic growth as a policy objective, but many important questions remain.

  19. Black and Korean: Racialized Development and the Korean American Subject in Korean/American Fiction

    Full Text Available This article examines the representation of the encounters and exchanges between Asian and black Americans in Sŏk-kyŏng Kang’s “Days and Dreams,” Heinz Insu Fenkl’s Memories of My Ghost Brother, and Chang-rae Lee’s A Gesture Life. While one popular mode of looking at Asian and black Americans relationally in the postwar era is to compare the success of Asian American assimilation to the failure of black Americans, Lim argues that such a mode of comparison cannot account for the ways in which Asian American racialization takes places within the global currents of militarism and migration. Against the popular view that attributes Asian American success to cultural difference, Lim relies on political scientist Claire Kim’s understanding of culture as something that is constructed in the process of racialization to explore how the above texts imagine the terms of comparative racialization between black and Asian Americans. The black-Korean encounters in these texts demand a heuristic of comparative racialization that goes beyond the discussion of the black-white binary as a national construct and seeks the reification and modification of this racial frame as it travels along the routes of US military and economic incursions in the Pacific. Lim suggests that the literary imagining of black-Korean encounters across the Pacific illustrates race and racialization as effects of a regime of economic development that is supported by military aggression.

  20. Assessing the economic benefits of vaccines based on the health investment life course framework: a review of a broader approach to evaluate malaria vaccination.

    Economic evaluations have routinely understated the net benefits of vaccination by not including the full range of economic benefits that accrue over the lifetime of a vaccinated person. Broader approaches for evaluating benefits of vaccination can be used to more accurately calculate the value of vaccination. This paper reflects on the methodology of one such approach - the health investment life course approach - that looks at the impact of vaccine investment on lifetime returns. The role of this approach on vaccine decision-making will be assessed using the malaria health investment life course model example. We describe a framework that measures the impact of a health policy decision on government accounts over many generations. The methodological issues emerging from this approach are illustrated with an example from a recently completed health investment life course analysis of malaria vaccination in Ghana. Beyond the results, various conceptual and practical challenges of applying this framework to Ghana are discussed in this paper. The current framework seeks to understand how disease and available technologies can impact a range of economic parameters such as labour force participation, education, healthcare consumption, productivity, wages or economic growth, and taxation following their introduction. The framework is unique amongst previous economic models in malaria because it considers future tax revenue for governments. The framework is complementary to cost-effectiveness and budget impact analysis. The intent of this paper is to stimulate discussion on how existing and new methodology can add to knowledge regarding the benefits from investing in new and underutilized vaccines.

  1. Health-related quality of life and economic impact of urinary incontinence due to detrusor overactivity associated with a neurologic condition: a systematic review

    Science.gov (United States)

    2013-01-01

    Background Patients with neurologic diseases often have neurogenic detrusor overactivity (NDO), which can result in a loss of voluntary bladder control and uncontrollable urinary incontinence (UI).The impact of UI due to NDO on patients’ lives has not been well studied. The objective of this review was to assess the health-related quality of life (HRQoL) and economic burden in patients with urgency UI due to NDO in select countries in North America, the European Union, Asia, and Australia. Methods Systematic literature searches and reviews of articles published in English (January 2000 to February 2011) were conducted using MEDLINE®, EMBASE®, and the Cochrane Library. Studies assessing the impact of UI on HRQoL of patients with an underlying neurologic condition of interest (i.e., multiple sclerosis, spinal cord injury, Parkinson’s disease, stroke, or spina bifida) were included. Economic studies in urgency UI also were included. Results Of 876 citations generated in the initial search, a total of 27 articles were deemed relevant: 16 articles presented HRQoL data and 11 articles presented information on the economic burden of UI. Humanistic studies used a range of HRQoL instruments to measure HRQoL burden, and the economic studies included different cost components to quantify the economic burden, making meaningful comparisons challenging. Despite this heterogeneity, the literature suggests that HRQoL in patients with UI due to NDO is worse than patients with UI in general or those with the same underlying neurologic condition without UI. In addition, urgency UI also results in substantial economic costs. Conclusions Incontinent patients with underlying neurologic conditions have impaired HRQoL as well as substantial economic burden attributable to UI due to NDO. There is a need for urgency UI treatments that improve HRQoL of these patients and alleviate the economic burden of this condition. PMID:23369111

    National surveys reveal notable individual differences in U.S. citizens’ attitudes toward freedom of expression, including freedom of the press and speech. Recent theoretical developments and empirical findings suggest that ecological factors impact censorship attitudes in addition to individual difference variables (e.g., education, conservatism), but no research has compared the explanatory power of prominent ecological theories. This study tested climato-economic, parasite stress, and life history theories using four measures of attitudes toward censoring the press and offensive speech obtained from two national surveys in the U.S.A. Neither climate demands nor its interaction with state wealth—two key variables for climato-economic theory—predicted any of the four outcome measures. Interstate parasite stress significantly predicted two, with a marginally significant effect on the third, but the effects became non-significant when the analyses were stratified for race (as a control for extrinsic risks). Teenage birth rates (a proxy of human life history) significantly predicted attitudes toward press freedom during wartime, but the effect was the opposite of what life history theory predicted. While none of the three theories provided a fully successful explanation of individual differences in attitudes toward freedom of expression, parasite stress and life history theories do show potentials. Future research should continue examining the impact of these ecological factors on human psychology by further specifying the mechanisms and developing better measures for those theories.

  7. From home to hospital and back again: economic restructuring, end of life, and the gendered problems of place-switching health services.

    Science.gov (United States)

    Cartier, Carolyn

    2003-06-01

    Economic restructuring in the health services industry in the USA exemplifies general patterns of economic change propelled by neoliberalism, especially industry privatization, diminished social services, and dependence on "flexible" labor and management regimes. Combined with the widespread entry of women into the labor force, an aging population, and minimal assistance for high quality long-term care at the end of life, these economic and social conditions raise a set of difficult policy questions for health services planning. Set in these broad contexts, this paper situates access to and experience of health services in the home, the hospital, and nursing facility, to demonstrate how economic changes have relocated and redefined health services in ways that distinctively impact how people experience the places where they receive care. This place switching of health services externalizes costs of subacute and "daily life care" (the so-called custodial care) to the sphere of the individual, their family, and communities. The theoretical analysis uses current geographical and philosophical approaches to place and space, and considers the tensions between institutionally managed health care space, and the patient's experience of receiving health services in place. The place/space dilemma of health services provision is examined through several interrelated subjects: long-term care at the end of life, gendered characteristics of care giving, the limitations of Medicare and Medicaid, historical changes in hospital length of stay, the restructuring of nursing practices, and the "no-care zone". The analysis is based on examples of stroke and incontinence care to demonstrate the importance of considering place and space issues in health care planning.

    2015-05-01

    Microalgae biofuel production has been extensively evaluated through resource, economic and life cycle assessments. Resource assessments consistently identify land as non-limiting and highlight the need to consider siting based on combined geographical constraints of land and other critical resources such as water and carbon dioxide. Economic assessments report a selling cost of fuel that ranges between $1.64 and over $30 gal(-1) consistent with large variability reported in the life cycle literature, -75 to 534 gCO2-eq MJ(-1). Large drivers behind such variability stem from differences in productivity assumptions, pathway technologies, and system boundaries. Productivity represents foundational units in these assessments with current assumed yields in various assessments varying by a factor of 60. A review of the literature in these areas highlights the need for harmonized assessments such that direct comparisons of alternative processing technologies can be made on the metrics of resource requirements, economic feasibility, and environmental impact.

  10. The number of life-history stages does not influence the androgen responsiveness to male-male interactions: sedentary and migratory black redstarts (Phoenicurus ochruros) do not elevate testosterone in response to simulated territorial intrusions.

    2014-09-01

    High plasma levels of testosterone at the beginning of the breeding season adjust male physiology for mating and promote territorial behavior in birds. Conversely intra-sexual competition may elicit a temporary increase in circulating testosterone. Male black redstarts (Phoenicurus ochruros) from migratory populations show the expected increase in baseline testosterone during early breeding, but circulating testosterone levels do not change in response to male-male interactions. Because sedentary populations express fewer life-history stages they may be more flexible in timing of life-history stages and more responsive to environmental modulation of hormone concentrations. Therefore, we tested whether the androgen responsiveness to male-male interactions differs between migratory (6 life-history stages) and sedentary black redstarts (3 life-history stages) during early breeding, predicting that in contrast to migratory birds, sedentary birds would modulate testosterone in response to simulated territorial intrusions (STI). In contrast to our prediction, sedentary males did not modulate post-capture testosterone levels in response to simulated territorial intrusions. Males of both populations increased testosterone after an injection of gonadotropin releasing hormone (GnRH), demonstrating that they were capable of increasing testosterone. Interestingly, in sedentary males the GnRH injection elicited a higher testosterone response in STI males than in control males. The two populations did not differ in their behavioral response to the STIs, except that sedentary males spent less time close to the decoy. In combination with previous data from black redstarts and other socially monogamous and biparental birds our current study adds to the growing evidence that current theory regarding hormone-behavior relationship needs to be refined.

    Landslide and flood events in Italy cause wide and severe damage to buildings and infrastructure, and are frequently involved in the loss of human life. The cost estimates of past natural disasters generally refer to the amount of public money used for the restoration of the direct damage, and most commonly do not account for all disaster impacts. Other cost components, including indirect losses, are difficult to quantify and, among these, the cost of human lives. The value of specific human life can be identified with the value of a statistical life (VLS), defined as the value that an individual places on a marginal change in their likelihood of death This is different from the value of an actual life. Based on information of fatal car accidents in Italy, we evaluate the cost that society suffers for the loss of life due to landslide and flood events. Using a catalogue of fatal landslide and flood events, for which information about gender and age of the fatalities is known, we determine the cost that society suffers for the loss of their life. For the purpose, we calculate the economic value in terms of the total income that the working-age population involved in the fatal events would have earned over the course of their life. For the computation, we use the pro-capita income calculated as the ratio between the GDP and the population value in Italy for each year, since 1980. Problems occur for children and retired people that we decided not to include in our estimates.

    This study was conducted to observe the effects of gas composition in modified atmosphere packaging (MAP) on the shelf-life of Longissimus dorsi of Korean Native Black Pigs-Duroc Crossbred (KNP×D) during refrigerated storage. Muscle sample was obtained from the left side of carcass of seven months old of KNP×D barrow. The sample was sliced into 1 cm in thickness, placed on trays (two slices/tray) and filled with different gas composition, i.e. 0:20:80/O2:CO2:N2 (MAP1), 30:20:50/O2:CO2:N2 (MAP2) and 70:20:10/O2:CO2:N2 (MAP3). Other slices of sample were vacuum packed (VP) as a control. All packs were stored at 5±1°C. At 12 d of storage, pH value of MAP2 and MAP3 were higher (p<0.05) than that of MAP1 and pH value of MAP1 was higher (p<0.05) than that of VP. At 6 d of storage, redness (a*) value of MAP2 and MAP3 were higher (p<0.05) than that of VP and MAP1 and, at 9 and 12 d of storage, redness value of MAP3 was higher (p<0.05) than that of VP, MAP1, and MAP2. At 3, 6, 9, and 12 d of storage, the 2-thiobarbituric acid reactive substances (TBARS) value of MAP3 was higher than that of MAP2 and TBARS value of MAP2 was higher than that of VP and MAP1. At 3, 6, 9, and 12 d of storage, volatile basic nitrogen values of MAP2 and MAP3 were higher (p<0.05) than those of VP and MAP1. At 3 d of storage, total aerobic plate counts of MAP2 and MAP3 were higher (p<0.05) than those of VP and MAP1 and, at 6 d of storage, total aerobic plate counts of MAP3 was higher (p<0.05) than that of MAP1 and MAP2. However, there was no significant different total aerobic plate count among MAP1, MAP2, and MAP3 at 9 and 12 d of storage. There was no significant different total anaerobic plate count among MAP1, MAP2, and MAP3 during storage. It is concluded that the MAP containing 30:20:50/O2:CO2:N2 gas composition (MAP2) might be ideal for better meat quality for KNP×D meat. PMID:25083110

  16. An Economic Model of Mortality Salience in Personal Financial Decision Making: Applications to Annuities, Life Insurance, Charitable Gifts, Estate Planning, Conspicuous Consumption, and Healthcare

    Directory of Open Access Journals (Sweden)

    Russell N James III

    2016-12-01

    Full Text Available The study of personal mortality salience and the denial of death have a long history in psychology leading to the modern field of Terror Management Theory. However, a simple consumer utility function predicts many of the outcomes identified in experimental research in this field. Further, this economic approach explains a range of otherwise unexpected financial decision-making behaviors in areas as diverse as annuities, life insurance, charitable gifts and bequests, intra-family gifts and bequests, conspicuous consumption, and healthcare. With its relevance to such a wide range of personal financial decisions, understanding the impact of mortality salience can be particularly useful to advisors in related fields.

  18. Atypical features of hyperthyroidism in Blacks

    Kalk, W.J.

    1980-01-01

    Hyperthyroidism is reportedly uncommon in the indigenous populations of Africa. The presenting symptoms volunteered, the symptoms elicited by direct questioning, and the results of physical examination were therefore prospectively compared in 60 Black and 56 White patients with thyrotoxicosis attending a single thyroid clinic. Fewer Blacks than Whites volunteered information about weight loss, while more Blacks complained only of the presence of a goitre. A 'chance' diagnosis of hyperthyroidism was made more frequently in Blacks. Symptomatology elicited by direct questioning and findings on physical examination were generally similar in each group, except that Blacks presented more frequently with complicated disease (cardiac failure and overt myopathy) and infiltrative ophthalmopathy. The frequency with which hyperthyroidism presents 'atypically' in Black compared with White patients may reflect educational, socio-economic and cultural differences in the Black and White populations, and may partly explain the infrequency with which this disease is diagnosed in Blacks

  1. Overview of the role of economics in plant life management license renewal in the U.S

    Young, G.G.; Nelson, A.P.

    2002-01-01

    Full text: In 1995, the U.S. Nuclear Regulatory Commission (NRC) published a revised rule in 10 CFR Part 54 that provides the requirements for an operating nuclear plant to seek license renewal. U.S. nuclear power plants obtain a 40-year initial operating license, but under 10 CFR Part 54, additional terms of 20-years each may be obtained through license renewal. Prior to 1995, the estimated cost just to prepare a license renewal application was about $40 million. Under the revised rule, the cost to prepare an application was reduced to about $10 million or less. Although the revised rule generated considerable interest, the decision to seek license renewal is fundamentally an economic decision. In 1995, many people believed that only a select few operating nuclear plants would pursue license renewal and that most would operate for no more than 40 years. The primary reason for this belief was that the cost of keeping U.S. nuclear plants running did not appear to be competitive with other forms of electricity generation. By 1998, the economic conditions in the U.S. were changing dramatically. Electricity deregulation was moving ahead, the need for electricity was growing, and the operating costs for nuclear power plants were declining. Also, in 1998, the first two applications for license renewal were submitted to the NRC by Baltimore Gas and Electric for the two-unit Calvert Cliffs nuclear power plant and by Duke Energy for the three-unit Oconee nuclear power plant. The U.S. nuclear industry was somewhat skeptical that the NRC could complete the license renewal process in a timely and predictable manner. This skepticism was due to the protracted and unpredictable process used by the NRC to approve the original operating licenses, especially in the 1980's and early 1990's. In March 2000, the NRC approved the renewal of the 40-year operating licenses for the two-unit Calvert Cliffs nuclear power plant for an additional 20 years. Two months later, the NRC approved the

    The relatively poor health of Black American people in the US and Black Caribbean people in England is a consistent finding in the health inequalities literature. Indeed, there are many similarities between the health, social, economic and demographic profiles of these two groups. However, there is evidence that Caribbean people in the US are faring considerably better. This paper explores differences in the social and economic position of Black American, Black Caribbean and white people in the US and Black Caribbean and white people in England, how these relate to ethnic inequalities in health, and may be underpinned by differences in patterns and contexts of migration. We use similar surveys from the US and England to explore these questions. The US data were drawn from the National Survey of American Life and the English data were drawn from the Health Survey for England and a follow up study. Findings show the advantaged health position of Caribbean American people in comparison with both Caribbean people in England and Black American people. Multivariate analyses indicate that these differences, and the differences in health between Black and white people in the two countries, are a consequence of social and economic inequalities.

    Hematopoietic stem cell transplantation is a demanding cancer treatment associated with enduring physical and psychological complications. Survivors' well-being may be further compromised by exposure to chronic stressors common to this population, including difficulties arising from costly medical care, changes in employment status, and health insurance coverage. Thus, we hypothesized that financial, employment, and insurance stressors (collectively referred to as economic survivorship stressors) would be associated with poorer health-related quality of life (HRQOL) among hematopoietic stem cell transplantation survivors. Survivors (n = 181; M = 640 days post-transplant) completed the measures of study variables through mailed questionnaires and telephone interviews. Hierarchical regression analyses were conducted to test the hypothesized associations between economic survivorship stressors and HRQOL, and to examine whether social and situational factors interact with survivors' stress perceptions to predict HRQOL. Greater financial and employment stress were associated with poorer functioning across multiple HRQOL domains, even after controlling for the effects of possible confounding sociodemographic and medical variables. Insurance stress was not associated with HRQOL. Some associations were moderated by situational factors including timing of the current financial crisis and portion of the transplant paid for by health insurance. Hematopoietic stem cell transplantation survivors can face serious economic challenges during recovery. Results suggest the value of viewing these challenges as chronic stressors capable of reducing survivors' mental and physical well-being. Identifying resources and skills that help survivors cope with these demands is an important goal for clinicians and researchers. Copyright © 2012 John Wiley & Sons, Ltd.

    Full Text Available Abstract Background Extreme obesity affects nearly 8% of Canadians, and is debilitating, costly and ultimately lethal. Bariatric surgery is currently the most effective treatment available; is associated with reductions in morbidity/mortality, improvements in quality of life; and appears cost-effective. However, current demand for surgery in Canada outstrips capacity by at least 1000-fold, causing exponential increases in already protracted, multi-year wait-times. The objectives and hypotheses of this study were as follows: 1. To serially assess the clinical, economic and humanistic outcomes in patients wait-listed for bariatric care over a 2-year period. We hypothesize deterioration in these outcomes over time; 2. To determine the clinical effectiveness and changes in quality of life associated with modern bariatric procedures compared with medically treated and wait-listed controls over 2 years. We hypothesize that surgery will markedly reduce weight, decrease the need for unplanned medical care, and increase quality of life; 3. To conduct a 3-year (1 year retrospective and 2 year prospective economic assessment of bariatric surgery compared to medical and wait-listed controls from the societal, public payor, and health-care payor perspectives. We hypothesize that lower indirect, out of pocket and productivity costs will offset increased direct health-care costs resulting in lower total costs for bariatric surgery. Methods/design Population-based prospective cohort study of 500 consecutive, consenting adults, including 150 surgically treated patients, 200 medically treated patients and 150 wait-listed patients. Subjects will be enrolled from the Edmonton Weight Wise Regional Obesity Program (Edmonton, Alberta, Canada, with prospective bi-annual follow-up for 2 years. Mixed methods data collection, linking primary data to provincial administrative databases will be employed. Major outcomes include generic, obesity-specific and preference

    The distribution and severity of dental caries among preschool children vary according to the socio-economic and ethnic differences within and between countries. Understanding socio-economic influences on child oral health could inform early interventions to reduce the oral health burden throughout the life-cycle. The aim of this study is to examine the socio-economic and ethnic influences on oral health among preschoolers in Kegalle, Sri Lanka. The study involved 784 children aged between 48-72 months recruited from 84 pre-schools in the Kegalle district in Sri Lanka. Cross-sectional data were collected by means of an oral examination of the children and a self-administered questionnaire to their parents/caregivers. The Early Childhood Oral Health Impact Scale (ECOHIS) was used to assess Oral Health related Quality of Life (OHQoL). Univariate and multivariate models of Poisson regression were used to investigate the associations between the variables. Compared to children whose fathers had tertiary education, those whose fathers did not study beyond grade 5, had more caries measured in terms of decayed, missing and filled surfaces (dmfs) (IRR = 2.30; 95% CI: 1.30, 4.06; p poor OHQoL at child (IRR = 2.52; 95% CI: 1.20, 5.31; p gingival bleeding (bleeding surfaces) (IRR = 3.04; 95% CI: 1.92, 4.81; p poor OHQoL at child level (IRR = 2.07; 95% CI: 1.19, 3.60; p poor OHQoL at family level (IRR = 1.42; 95% CI: 1.10, 1.84; p oral health outcomes exist among this population of preschoolers. Interventions targeting children of fathers with low educational levels and ethnic minority groups are required to reduce inequalities in oral health in Sri Lanka and other similar countries.

    The SMART trial is a UK-based, multicentre RCT comparing prophylactic radiotherapy and symptom-based (deferred) radiotherapy in 203 patients with Malignant Pleural Mesothelioma who had undergone large bore pleural interventions. Using costs and quality of life data collected alongside the clinical trial, we will estimate the cost-effectiveness of prophylactic radiotherapy compared to deferred radiotherapy over a 1-year period. Healthcare utilization and costs were captured during the trial. Utility weights produced by the EQ-5D questionnaire were used to determine quality-adjusted life-years (QALY) gained. The incremental cost-effectiveness ratio was calculated over the one-year trial period. Costs were similar in the immediate and deferred radiotherapy groups: £5480.40 (SD = £7040; n = 102) and £5461.40 (SD = £7770; n = 101) respectively. There was also no difference in QALY: 0.498 (95% CI: [0.45, 0.547]) in the prophylactic radiotherapy group versus 0.525 (95% CI: [0.471, 0.580]) in the deferred group. At a willingness to pay threshold of £30,000/QALY there was only a 24% chance that prophylactic radiotherapy was cost-effective compared to deferred radiotherapy. There was no significant effect of prophylactic radiotherapy on quality of life in the intervention group, nor was there any discernable decrease in healthcare costs. There is little evidence to suggest that prophylactic radiotherapy is a cost-effective intervention in this population. ISRCTN72767336 with ISRCTN.

    2017-10-01

    Full Text Available Potato liquor, a byproduct of potato starch production, is steam-treated to produce protein isolate. The heat treated potato liquor (HTPL, containing significant amounts of organic compounds, still needs to be further treated before it is discarded. Presently, the most common strategy for HTPL management is concentrating it via evaporation before using it as a fertilizer. In this study, this scenario was compared with two biotreatments: (1 fermentation using filamentous fungus R. oryzae to produce a protein-rich biomass, and (2 anaerobic digestion of the HTPL to produce biogas. Technical, economic and environmental analyses were performed via computational simulation to determine potential benefits of the proposed scenarios to a plant discarding 19.64 ton/h of HTPL. Fungal cultivation was found to be the preferred scenario with respect to the economic aspects. This scenario needed only 46% of the investment needed for the evaporation scenario. In terms of the environmental impacts, fungal cultivation yielded the lowest impacts in the acidification, terrestrial eutrophication, freshwater eutrophication, marine eutrophication and freshwater ecotoxicity impact categories. The lowest impact in the climate change category was obtained when using the HTPL for anaerobic digestion.

  12. Psychopathology and prosocial behavior in adolescents from socio-economically disadvantaged families: the role of proximal and distal adverse life events.

    The study investigated if proximal contextual risk (number of adverse life events experienced in the last year) or distal contextual risk (number of adverse life events experienced before the last year) is a better predictor of adolescent psychopathology and prosocial behavior. It also tested for the specificity, accumulation and gradient of contextual risk in psychopathology and prosocial behavior, and for the interaction between proximal and distal contextual risk in psychopathology and prosocial behavior. The sample was 199 11-18 year old children from a socio-economically disadvantaged area in North-East London. The Strengths and Difficulties Questionnaire (SDQ), which measures four difficulties (hyperactivity, emotional symptoms, conduct problems, and peer problems) and prosocial behavior, was used. Confounders were age, gender, and maternal educational qualifications. To model the relationship between the five SDQ scales and contextual risk multivariate response regression models and multivariate response logistic regression models that allow the error terms of the scale specific models to be correlated were fitted. This study highlighted the importance of proximal contextual risk in predicting both broad and externalizing psychopathology, and the importance of considering risk accumulation rather than specificity in predicting psychopathology. By showing that the number of proximal adverse life events experienced had a steady, additive effect on broad and externalizing psychopathology, it also highlighted the need to protect adolescents experiencing current risk from further risk exposure. By showing that the number of distal adverse life events experienced did not affect the proximal risk's impact on either broad or externalizing psychopathology, it highlighted the need to protect all adolescents, irrespective of experience of early life adversities, from risk.

    Over recent years, public involvement in health research has expanded considerably. However, public involvement in designing and conducting health economics research is seldom reported. Here we describe the development, delivery and assessment of an approach for involving people in a clearly defined piece of health economics research: selecting health states for valuation in estimating quality-adjusted life-years (QALYs). This involvement formed part of a study to develop a condition-specific preference-based measure of health-related quality of life, the Multiple Sclerosis Impact Scale (MSIS-8D), and the work reported here relates to the identification of plausible, or realistic, health states for valuation. An Expert Panel of three people with multiple sclerosis (MS) was recruited from a local involvement network, and two health economists designed an interactive task that enabled the Panel to identify health states that were implausible, or unlikely to be experienced. Following some initial confusion over terminology, which was resolved by discussion with the Panel, the task worked well and can be adapted to select health states for valuation in the development of any preference-based measure. As part of the involvement process, five themes were identified by the Panel members and the researchers which summarised our experiences of public involvement in this health economics research example: proportionality, task design, prior involvement, protectiveness and partnerships. These are described in the paper, along with their practical implications for involving members of the public in health economics research. Our experience demonstrates how members of the public and health economists can work together to improve the validity of health economics research. Plain Language Summary It has become commonplace to involve members of the public in health service research.

    2015-01-01

    Highlights: • Assessment of economics and sustainability of thermochemical ethanol production. • Exploitation of excess CO 2 saving by either importing fossil energy or CO 2 trading. • Significant increase in alcohol production by replacing biomass with natural gas. • CO 2 emission trading is not cost-competitive versus import of fossil energy. • Lowest ethanol production cost for partial oxidation as reforming technology. - Abstract: In this work, two options are investigated to enhance the economics of the catalytic production of bioethanol from biomass gasification by exploiting the excess of CO 2 emission saving: (i) to import fossil energy, in the form of natural gas and electricity or (ii) to trade CO 2 emissions. To this end, an integrated life cycle and economic assessment is carried out for four process configurations, each using a different light hydrocarbon reforming technology: partial oxidation, steam methane reforming, tar reforming and autothermal reforming. The results show that for all process configurations the production of bioethanol and other alcohols significantly increases when natural gas displaces biomass, maintaining the total energy content of the feedstock. The economic advantage of the partial substitution of biomass by natural gas depends on their prices and this is explored by carrying out a sensitivity analysis, taking historical prices into account. It is also concluded that the trade of CO 2 emissions is not cost-competitive compared to the import of natural gas if the CO 2 emission price remains within historical European prices. The CO 2 emission price would have to double or even quadruple the highest CO 2 historical price for CO 2 emission trading to be a cost-competitive option

  17. Species delimitation in asexual insects of economic importance: The case of black scale (Parasaissetia nigra, a cosmopolitan parthenogenetic pest scale insect.

    Directory of Open Access Journals (Sweden)

    Yen-Po Lin

    Full Text Available Asexual lineages provide a challenge to species delimitation because species concepts either have little biological meaning for them or are arbitrary, since every individual is monophyletic and reproductively isolated from all other individuals. However, recognition and naming of asexual species is important to conservation and economic applications. Some scale insects are widespread and polyphagous pests of plants, and several species have been found to comprise cryptic species complexes. Parasaissetia nigra (Nietner, 1861 (Hemiptera: Coccidae is a parthenogenetic, cosmopolitan and polyphagous pest that feeds on plant species from more than 80 families. Here, we implement multiple approaches to assess the species status of P. nigra, including coalescence-based analyses of mitochondrial and nuclear genes, and ecological niche modelling. Our results indicate that the sampled specimens of P. nigra should be considered to comprise at least two ecotypes (or "species" that are ecologically differentiated, particularly in relation to temperature and moisture. The presence of more than one ecotype under the current concept of P. nigra has implications for biosecurity because the geographic extent of each type is not fully known: some countries may currently have only one of the biotypes. Introduction of additional lineages could expand the geographic extent of damage by the pest in some countries.

    Research purpose: The objective of the research was to investigate the relation between adultlearners’ cognitive learning strategies (measured by the examination preparation inventoryand their psychosocial employability attributes (measured by the employability attributesscale. Motivation for the study: Recent research has made important progress in understanding thenotions of cognitive learning styles in learning and psychosocial employability attributes insustaining individuals’ employability in the contemporary world of work. However, researchon how adult learners’ cognitive learning strategies influence the psychosocial attributes theyneed to manage and sustain their employability has been lacking. Research approach, design and method: A quantitative cross-sectional survey design wasused, involving a stratified proportional random sample of 1102 predominantly early careerblack female undergraduate level adult learners. The participants were enrolled for distancelearning studies in the economic and management sciences field at a South African highereducation institution. Main findings: Canonical correlation and multiple regression analysis indicated the abstracttheoretical and factual practical cognitive learning strategies as useful predictors of theparticipants’ overall level of psychosocial employability attributes and especially their levelsof career self-management and proactivity. Practical/managerial implications: Learning practitioners should strive to integrate cognitivelearning strategies in the design of learning and assessment activities in order to fosterthe psychosocial employability attributes adult learners need to manage their continuedemployability in the contemporary workplace. Contribution: The study contributes new insights to the employability and learning andeducation literature. The results may potentially inform formal learning and assessmentdesign in order to improve adult learners’ learning performance and employability.

    2014-05-01

    Given the increasing lack of medical doctors in Germany, this study aimed to investigate the professional situation and the push and pull factors of German medical specialists working in Austrian hospitals. This explorative study is based on semi-structured interviews with 14 specialists working in Austria, who completed their education partly or fully in Germany. The material has been interpreted using qualitative content analysis. Better work-life balance, higher quality of life and more favourable working conditions represent major reasons for German specialists to stay in Austria. Moreover, the higher density of medical doctors in Austrian hospitals can have an impact on the distribution of responsibilities among health-care personnel, and on hospital performance. In the light of recent reforms in the German health-care system, the study underlines the importance of qualitative factors for the satisfaction of German medical doctors. These factors should be further analysed in order to avoid a brain drain of high-qualified health care staff in the future. © Georg Thieme Verlag KG Stuttgart · New York.

A bottom-up cost-of-illness, cross-sectional, retrospective analysis of 74 patients was conducted aiming to estimate the economic impact of CF. Data on demographic characteristics, health resource utilisation, informal care, productivity losses and HRQOL were collected from questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D) instrument. Using unit costs for 2012 we found that the average annual cost for a CF patient was €48,603, with direct health care costs amounting to €20,854 (42.9 % of total costs), direct non-health care costs being €21,528 (44.3 %) and indirect costs attributable to productivity losses being €6,222 (12.8 %). On average, the largest expenditures by far were accounted for by informal care (44.1 %), followed by medications (14.5 %), acute hospitalisations (13.9 %), early retirement (9.1 %) and outpatient and primary health care visits (7.9 %). Sharp differences existed depending on whether CF patients were in need of caregiver help (€76,271 versus €26,335). In adult CF patients, mean EQ-5D index scores were 0.64 (0.93 in the general population) and mean EQ-5D visual analogue scale scores were 62.23 (86.84 in the general population); among caregivers, these scores were 0.836 and 80.85, respectively. Our analysis highlights the importance of the economic and quality of life consequences of CF from a societal perspective. The results highlight that beyond conventional costs such as acute hospitalisations, medication and outpatient and primary care visits, indirect costs related to informal care and early retirement, have significant societal implications. Similarly, our analysis showed that the average EQ-5D index score of adult CF patients was significantly lower than in the general population, an indication that a methodological bias

    Full Text Available A socio-economic study of Suplit Stone breaker women In Supporting Family life is a study of the Informal Sector Workers carried out in the form of a survey. This study aims to assess the socio-economic level of the workers, educational level, results achieved, income levels, health effects, and household's social condition. This research will specifically study and analyze income received, identify and examine the issues that arise in performing stone breaker as an occupation: deficiencies, expectations, and negative impacts. Ten urban villages/villages in Moramo North District was taken as research population. Area samples taken were five (5 urban/rural where workers are concentrated in Lalowaru Village, Puasana Village, Mata Mawatu Village, Sanggula Village, and Lamokula Village. Samples community were 5 percent of all household. Therefore total samples taken were 93 people scattered in villages. Research informants are Head of North Morano district, Stone Processing owner, and stone carrier driver. Data collection was conducted by observation, interview using a list of questions, as well as documentation of objective conditions. Data were analyzed using descriptive analysis techniques, which describe the objective conditions of the field in accordance with the purpose of research. Research result shows workers are housewives who help their husbands and families to supplement the household income to support family life. In general, socio-economic conditions of women suplit stone breaker is relatively low, their education level is generally elementary or none. The results achieved are still limited by an average of IDR 30,000, per day/worker is calculated based on the total stone yield. These women perform their work using simple tools such as hammer and gloves. The negative impact on eye health and breathing difficulty caused by inhaling stone dust every day. The problems faced by the workers is the lack of working capital to be trying to own

    Sense of control over life has been shown to have protective health effects in studies that have mostly enrolled White middle class individuals. It is unknown, however, whether populations differ in the protective health gain associated with sense of control over life. This study compared a nationally representative sample of Black and White older adults for protective effects of sense of control over life on short-term risk of all-cause mortality in the United States. This longitudinal prospective study followed 1,493 White ( n = 759) and Black ( n = 734) older adults (age 66 or more) from 2001 to 2004. Race, demographics, socio-economics, sense of control over life, health behaviors, and self-rated health were measured at baseline in 2001. Outcome was all-cause mortality occurring between 2001 and 2004. Logistic regression models were used for data analysis. In the pooled sample, sense of control over life was protective against 3-year mortality risk above and beyond demographics, socio-economics, health behaviors, and self-rated health. We found a race by sense of control over life interaction, suggesting a stronger protective effect of control over life on mortality risk for Whites compared to Blacks. In race-specific models, sense of control over life at baseline was predictive of mortality among Whites but not Blacks. In the United States, Black older adults do not gain a survival benefit associated with high levels of sense of control over life, as do their White counterparts. It is not clear why sense of control over life translates into survival for Whites but not for Blacks.

    Economic crime, often also referred to as white collar crime, is one of the most incidious and predatory of offenses. Unlike street crime, for which there may well be some protection, the average citizen is completely at the mercy of the perpetrators of economic crimes. The concept of white collar crime was first identified by Edwin H. Sutherland. He dealt with the problem as a violation of trust involving either or both misrepresentation and duplicity. He argued for the use of criminal sanctions rather than civil remedies as a means of dealing with white collar offenses. Sutherland's views were attacked by the legal profession, by sociologists and criminologists and by public opinion specialists. They contended that an act treated in civil court is not a crime; that criminals are those persons who are defined as such and white collar criminals are neither so defined nor do they define themselves as criminals and, finally, that economic crime is universal. Can anyone be criminal, then, ask the critics? A number of studies by Clinard, Quinney, Black, Ball, Cressey, Newman and others have translated the interest in white collar crime into empirical terms. The last thirty-five years have also witnessed the elaboration and alteration of the theory itself. Geis' work has been particularly important in this respect. His "street" versus "suite" crime is a useful dichotomy. Most important, however, have been the monograph and papers by Herbert Edelhertz who has conceptualized the issues on various levels - from consumer fraud to the illegal activities of the multinational corporation. This article is concerned with the exposition of the theory and research in the field. Most significant, the paper raises serious doubts whether the problem of economic crime can be researched and studied; it raises even more difficult issues concerning the legal and sociological implications of economic crime and of its prevention, management and control.

    Fragile X syndrome (FXS) is the main hereditary cause of intellectual disability. Although the associated burden appears to be considerable, to date no study has comprehensively assessed the cost incurred because of FXS, including its specific impact on health-related quality of life and the burden on caregivers using standardised quantitative tools. The aim of this article is to provide data in order to increase awareness of the repercussions of FXS on patients and caregivers as well as on the health and social care systems in France. A retrospective cross-sectional study was carried out on 145 patients recruited through Le Goëland X-Fragile and Mosaïques, the French FXS patient associations. Data on their demographic characteristics and resource use were obtained from an online questionnaire, and costs were estimated by a bottom-up approach. The EQ-5D health questionnaire was used to measure patients' and caregivers' health-related quality of life. Perceived burden of care was measured using the Zarit Caregiver Burden Interview. The Barthel index, a non-utility-based assessment, was used to measure patients' level of dependence. The annual total direct cost of FXS was estimated at €25 800 per patient. The main contributors were informal care provided by the main caregiver (€10 500) and social services (€8400). Healthcare costs, estimated at €2700, represented only a minor share. Mean EQ-5D utility scores were 0.49 for patients and 0.75 for caregivers. The mean burden for caregivers as measured by the Zarit Caregiver Burden Interview was 39.9. Fragile X syndrome requires significant resources that are mainly of a non-medical nature and are higher for children than for adults. Compared with related diseases, it constitutes a particularly high burden for caregivers. Using a bottom-up approach and a wide range of standardised measures, this study underscores the need for greater awareness of the burden of FXS as well as an assessment of new and existing

    Osteoporosis remains undertreated in Japan, and bone fractures are the most frequent complications imposing heavy burden on individuals and the community. This paper investigates the clinical and economic burden of fractures among osteoporosis patients in Japan. The Japan National Health and Wellness Survey 2012-2014 database was used for analysis. Respondents aged ≥ 50 years and indicated a physician diagnosis of osteoporosis (N = 1107) were categorized into three subgroups: no prior fracture (N = 693), single fracture (N = 242), and multiple (≥ 2) fractures (N = 172). Health-related quality of life (HRQoL), work productivity and activity impairment, healthcare resource utilization and associated direct and indirect costs were compared across three fracture subgroups adjusting for respondents' sociodemographic and clinical characteristics using generalized linear regression models. The estimated fracture prevalence among respondents with osteoporosis who were ≥ 50 years was 37.4%, of whom 41.5% had multiple fractures. Relative to osteoporosis respondents with no fracture and with single fracture, those with multiple fractures reported significant higher disability in HRQoL, more healthcare resource utilization, and were associated with higher direct costs. Improved treatment of fractures among osteoporosis patients is necessary and may help reduce the clinical and economic burden in this osteoporosis population.

    The productivity of countries around the globe is adversely affected by the health-related problems of their labour force. This study examined the effect of the prevalence of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and life expectancy on the economic growth of 33 Sub-Saharan African (SSA) countries over a period of 11 years (2002-2012). The study employed a dynamic panel approach as opposed to the static traditional approach utilised in the literature. The dynamic approach became eminent because of the fact that HIV/AIDS is a dynamic variable as its prevalence today depends on the previous years. The result revealed that HIV/AIDS is negatively correlated with economic growth in the region, with a coefficient of 0.014, and significant at the 1% level. That is, a 10% increase in HIV/AIDS prevalence leads to a 0.14% decrease in the GDP of the region. Tackling HIV/AIDS is therefore imperative to the developing Sub-Saharan African region and all hands must be on deck to end the menace globally.

  9. Life-cycle environmental and economic impacts of energy-crop fuel-chains: an integrated assessment of potential GHG avoidance in Ireland

    2008-01-01

    This paper combines life-cycle analyses and economic analyses for Miscanthus and willow heat and electricity fuel-chains in Ireland. Displaced agricultural land-uses and conventional fuels were considered in fuel-chain permutations. Avoided greenhouse gas (GHG) emissions ranged from 7.7 to 35.2 t CO 2 eq. ha -1 a -1 . Most fuel-chain permutations exhibited positive discounted financial returns, despite losses for particular entities at a farm-gate processed-biomass price of Euro 100 t -1 dry-matter. Attributing a value of Euro 10 t -1 CO 2 eq. to avoided GHG emissions, but subtracting financial returns associated with displaced fuel supplies, resulted in discounted annual national economic benefits (DANEBs) ranging from -457 to 1887 Euro ha -1 a -1 . Extrapolating a plausible combination of fuel-chains up to a national indicative scenario resulted in GHG emission avoidance of 3.56 Mt CO 2 eq. a -1 (5.2% of national emissions), a DANEB of 167 M Euro , and required 4.6% of national agricultural land area. As cost-effective national GHG avoidance options, Miscanthus and willow fuel-chains are robust to variation in yields and CO 2 price, and appear to represent an efficient land-use option (e.g. compared with liquid biofuel production). Policies promoting utilisation of these energy-crops could avoid unnecessary, and environmentally questionable, future purchase of carbon credits, as currently required for national Kyoto compliance

    This study investigates the use of "real options analysis" (ROA) to quantify the value of greater product flexibility at algal biofuel production facilities. A deterministic optimization framework is integrated with a combined life cycle assessment/techno-economic analysis model and subjected to an ensemble of 30-year commodity price trajectories. Profits are maximized for two competing plant configurations: 1) one that sells lipid-extracted algae as animal feed only; and 2) one that can sell lipid-extracted algae as feed or use it to recover nutrients and energy, due to an up-front investment in anaerobic digestion/combined heat and power. Results show that added investment in plant flexibility does not result in an improvement in net present value, because current feed meal prices discourage use of lipid-extracted algae for nutrient and energy recovery. However, this study demonstrates that ROA provides many useful insights regarding plant design that cannot be captured via traditional techno-economic modeling. Copyright © 2016 Elsevier Ltd.

    To perform an economic evaluation of a primary care-based physical activity counseling intervention that improved physical activity levels and rapid gait speed in older veterans. Secondary objective of randomized trial that assessed the effect of exercise counseling (relative to usual care) on physical performance, physical activity, function, disability, and medical resource use and cost. Veterans Affairs Medical Center, Durham, North Carolina. Male veterans aged ≥70 years (n = 398). An experienced health counselor provided baseline in-person exercise counseling, followed by telephone counseling at 2, 4, and 6 weeks, and monthly thereafter through one year. Each participant's primary care physician provided initial endorsement of the intervention, followed by monthly automated telephone messages tailored to the patient. Individualized progress reports were mailed quarterly. Intervention costs were assessed. Health care resource use and costs were estimated from enrollment through one year follow-up. The incremental cost of achieving clinically significant changes in major trial endpoints was calculated. The total direct cost of the intervention per participant was $459, 85% of which was counselor effort. With overhead, program cost totaled $696 per participant. Medical costs during follow-up reached $10,418 with the intervention, versus $12,052 with usual care (difference = -$1,634 (95% confidence interval = -$4,683 to $1,416; P = .29)). Expressed in terms of short-term clinical outcomes, the intervention cost $4,971 per additional patient reaching target exercise levels, or $4,640 per patient achieving a clinically significant change in rapid gait speed. Improvements in physical activity and rapid gait speed in the physical activity counseling group were obtained at a cost that represents a small fraction of patients' annual health care costs. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

  12. Field-to-Fuel Performance Testing of Lignocellulosic Feedstocks for Fast Pyrolysis and Upgrading: Techno-economic Analysis and Greenhouse Gas Life Cycle Analysis

    This work shows preliminary results from techno-economic analysis and life cycle greenhouse gas analysis of the conversion of seven (7) biomass feedstocks to produce liquid transportation fuels via fast pyrolysis and upgrading via hydrodeoxygenation. The biomass consists of five (5) pure feeds (pine, tulip poplar, hybrid poplar, switchgrass, corn stover) and two blends. Blend 1 consists of equal weights of pine, tulip poplar and switchgrass, and blend 2 is 67% pine and 33% hybrid poplar. Upgraded oil product yield is one of the most significant parameters affecting the process economics, and is a function of both fast pyrolysis oil yield and hydrotreating oil yield. Pure pine produced the highest overall yield, while switchgrass produced the lowest. Interestingly, herbaceous materials blended with woody biomass performed nearly as well as pure woody feedstock, suggesting a non-trivial relationship between feedstock attributes and production yield. Production costs are also highly dependent upon hydrotreating catalyst-related costs. The catalysts contribute an average of ~15% to the total fuel cost, which can be reduced through research and development focused on achieving performance at increased space velocity (e.g., reduced catalyst loading) and prolonging catalyst lifetime. Green-house-gas reduction does not necessarily align with favorable economics. From the greenhouse gas analysis, processing tulip poplar achieves the largest GHG emission reduction relative to petroleum (~70%) because of its lower hydrogen consumption in the upgrading stage that results in a lower natural gas requirement for hydrogen production. Conversely, processing blend 1 results in the smallest GHG emission reduction from petroleum (~58%) because of high natural gas demand for hydrogen production.

    This study explored the influence of satisfaction with economic and social rights (ESR) on the quality of life (QOL) of people in post-disaster zones in Sichuan, China. Data from a survey conducted in 2013 in the 5 hardest hit counties in the earthquake-prone area of Sichuan were used. QOL was measured by use of the brief version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF). Structural equation models were developed to determine the specific features of the influence of satisfaction with ESR on QOL. The mean values of both the WHOQOL-BREF scale and the ESR satisfaction scale were lower than the midpoint of the scales. Satisfaction with ESR had a significant effect on psychological health, social relationships, and environment, apart from physical health. Satisfaction with the right to food had the greatest effect on QOL, followed by the rights to education, work, health, social security, and housing. Satisfaction with ESR had a significant positive influence on the QOL of people in a post-disaster zone, particularly satisfaction with the right to food. Policies on food and education guarantees and mental health intervention are highlighted.

    The prevalence of obesity among Italian children has reached such alarming levels as to require detailed studies of the causes of the phenomenon. A cross-sectional study was carried out in order to assess the weight status of 1164 Italian children aged 6-8 years (the Monitoring Air Pollution Effects on Children for Supporting Public Health Policy (MAPEC_LIFE) cohort) and to identify any associations between selected socio-economic and environmental factors and overweight/obesity. The data were obtained by means of a questionnaire given to parents, and any associations were examined by binomial logistic regression analyses. Overweight was found to be positively associated with male gender, parents of non-Italian origin, and parents who smoke, and negatively associated with the parents' level of education and employment. In addition, the frequency of overweight varied in relation to the geographical area of residence, with a greater prevalence of overweight children in the cities of central-southern Italy. This study highlights the need to implement appropriate obesity prevention programs in Italy, which should include educational measures concerning lifestyle for parents from the earliest stages of their child's life.

    Full Text Available The research on work-life conflict (WLC is largely neglected in occupational medicine and public health and typically limited to white-collar workers and public servants. This study therefore aims to explore possible differences in the prevalence of WLC and its association with health outcomes between white- and blue-collar workers from different work environments in Switzerland. Cross-sectional survey data collected in 2007 in the service sector and in 2010 in the industrial sector were used for statistical analyses. A subsample of university graduates employed by large service companies (N=1,170 from the first survey’s population was taken and compared with a subsample of low or unskilled industrial and construction workers with no or only compulsory education (N=489 from the second survey’s population. The results show almost consistently, and particularly in women, a lower prevalence of time- and strain-based forms and both causal directions of WLC in blue-collar workers. However, associations between different WLC measures and general, physical and mental health outcomes were found to be equally strong or even stronger among blue-collar workers compared to white-collar workers. Low or unskilled industrial and construction workers are less frequently affected by higher degrees of WLC but are then at no lower risk of suffering poor self-rated health or severe backaches and sleep disorders than university graduates working in the service sector with comparable exposure to WLC. In conclusion it can be stated that WLC turned out to be much less prevalent but equally or even more detrimental to health in blue-collar workers, who therefore need to be considered in future studies.

    Wasko, Frank

    Traditionally, electric utilities have been slow to change and very bureaucratic in nature. This culture, in and of itself, has now contributed to a high percentage of United States electric utilities operating uneconomical nuclear plants (Crooks, 2014). The economic picture behind owning and operating United States nuclear plants is less than favorable for many reasons including rising fuel, capital and operating costs (EUCG, 2012). This doctoral dissertation is specifically focused on life without nuclear power. The purpose of this dissertation is to create a model and guide that will provide electric utilities who currently operate or will operate uneconomical nuclear plants the opportunity to economically assess whether or not their nuclear plant should be retired. This economic assessment and stakeholder analysis will provide local government, academia and communities the opportunity to understand how Southern California Edison (SCE) embraced system upgrade import and "voltage support" opportunities to replace "base load" generation from San Onofre Nuclear Generating Station (SONGS) versus building new replacement generation facilities. This model and guide will help eliminate the need to build large replacement generation units as demonstrated in the SONGS case analysis. The application of The Nuclear Power Retirement Model and Guide will provide electric utilities with economic assessment parameters and an evaluation assessment progression needed to better evaluate when an uneconomical nuclear plant should be retired. It will provide electric utilities the opportunity to utilize sound policy, planning and development skill sets when making this difficult decision. There are currently 62 nuclear power plants (with 100 nuclear reactors) operating in the United States (EIA, 2014). From this group, 38 are at risk of early retirement based on the work of Cooper (2013). As demonstrated in my model, 35 of the 38 nuclear power plants qualify to move to the economic

    Full Text Available This article aims to highlight the quality of life that depends on necessary, harmonious and simultaneous satisfying of all human needs, instead of „one at a time”, health and economic insecurity being at the very foundation of it. A society that is focused on quality of life will be a society centered on the individual, their needs and aspirations. It needs to offer alternatives and choices of the individual and not to impose models. Coercion of society over the individual is an objective and necessary phenomenon. Its deepening is not, however, as required. Social environment based on quality of life must be characterized by the maximum possible degree of permissiveness in which the individual is educated in its contribution to social awareness.

Marine sediment samples were collected in 2015 from the same fifteen sampling points, and the activity concentrations of 226Ra, 232Th, 40K and 137Cs were determined for the sediment samples. The activity concentrations ranged from 10.94-25.95, 12.14-33.05, 265.74-459.89 and 2.08-37.45 Bq kg- 1 for 226Ra, 232Th, 40K and 137Cs respectively. The results showed that there was a steep decline in 137Cs within the sediment at most of the sampling sites from the Eastern Black Sea region during the 22-year period, except for two sites at which the measured levels were much higher. This may be the result of the combined effects of radioactive contaminant entry into this area from rivers, environmental changes and nuclear testing between 1993 and 2015. Furthermore, the ecological half-life (EHL) of the 137Cs radionuclide was estimated for the sediment samples, and radiological hazard parameters such as the absorbed dose rate in air (D), the annual effective dose equivalent (AEDE) and the excess lifetime cancer risk (ELCR) were calculated and compared with the international recommended values. It was shown that these sediments do not present any significant health risk for humans in this area.

    2008-01-01

    In this month's European column, Jean-Francois Drevet examines the issues that arise for Europe from the Black Sea region. The Black Sea is increasingly becoming a crucial place of transit for hydrocarbon imports from the Caspian and Russia into the European Union. The considerable increase in this traffic raises both environmental problems (the risk of oil slicks) and issues of security of supply, on account of the economic and political fragility of some of the bordering or neighbouring states (Ukraine, Georgia, Armenia, Azerbaijan, Russia/Chechnya etc.). This is why, as Jean-Francois Drevet stresses, the European Union has been trying since the mid-1990's to claim a role in the management of the affairs of the region. With two bordering states (Rumania and Bulgaria) joining the EU in 2007, cooperation in the Black Sea has become a priority within the framework of the European Neighbourhood Policy, and this column delineates a number of the obstacles that still have to be surmounted.

    To perform a systematic review of the health-related quality of life (HRQoL) and economic burdens of anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). A systematic literature search of English-language studies was performed in Medline, Embase, PsycINFO, PsycARTICLES, Academic Search Complete, CINAHL Plus, Business Source Premier, and Cochrane Library. Cost data were converted to 2014 Euro. Sixty-nine studies were included. Data on HRQoL were reported in 41 studies (18 for AN, 17 for BN, and 18 for BED), on healthcare utilization in 20 studies (14 for AN, 12 for BN, and 8 for BED), and on healthcare costs in 17 studies (9 for AN, 11 for BN, and only 2 for BED). Patients' HRQoL was significantly worse with AN, BN, and BED compared with healthy populations. AN, BN, and BED were associated with a high rate of hospitalization, outpatient care, and emergency department visits. However, patients rarely received specific treatment for their eating disorder. The annual healthcare costs for AN, BN, and BED were €2993 to €55,270, €888 to €18,823, and €1762 to €2902, respectively. AN, BN, and BED have a serious impact on patient's HRQoL and are also associated with increased healthcare utilization and healthcare costs. The burden of BED should be examined separately from that of BN. The limited evidence suggests that further research is warranted to better understand the differences in long-term HRQoL and economic burdens of AN, BN, and BED.

    Full Text Available Abstract Background Differences in life expectancy (LE between social groups in a specific country are a fundamental measure of health inequalities within that country. Constant monitoring of these differences provides important information on the population's general health. The purpose of the present study is to explore and quantify the socio-economic differences in LE in Germany, focussing on a topic rarely assessed in other studies, the dependency of these LE differences on the presence of myocardial infarction or diabetes mellitus. Methods The dataset consists of 13,427 participants (6,725 men, 6,702 women aged 25-74 years, recruited in the region of Augsburg in Germany through three independent cross-sectional representative surveys conducted in 1984/85, 1989/90, 1994/95, with a mortality follow up in 1998 and 2002. We use a parametric model for the survival function based on the Weibull distribution, in which the hazard function is described in terms of two parameters. We estimate these parameters with a maximum likelihood method that takes into account censoring and data truncation. Results The difference in LE between the lowest and the highest socio-economic group is estimated to be 3.79 years for men and 4.10 years for women. Diabetes mellitus reduces LE of men from the upper three income quartiles by 4.88 years, and LE of men belonging to the lowest income quartile by 7.97 years. For women, the corresponding figures are 5.79 and 5.72 years. Myocardial infarction reduces LE of men and women from the upper three income quartiles by 3.65 and 3.75 years, respectively, and LE of men and women belonging to the lowest income quartile by 5.11 and 10.95 years, respectively. Conclusions This study shows that in Germany the differences in LE by socio-economic status are comparable to those found in other European countries, and that these differences seem to increase when diabetes mellitus or myocardial infarction is present.

    Full Text Available INTRODUCTION: Considerable evidence suggests that patients with more advantaged Socio-Economic Positions undergo Total Hip and Knee Replacement (THR/TKR more often, despite having a lower need. We questioned whether more disadvantaged Socio-Economic Position is associated with an lower improvement in Health-Related Quality of Life (HRQoL and a lower patient satisfaction after THR/TKR. METHODS: Patients who underwent primary THR/TKR in one academic and three community hospitals between 2005 and 2009, were eligible for inclusion. The highest completed levels of schooling were aggregated to index social class. We compared the improvement in HRQoL and postoperative satisfaction with surgery (measured using the Short-Form 36 (SF36 and an 11-point numeric rating scale of satisfaction between the aggregated groups of highest completed levels of schooling, using linear mixed model analysis, with center as a random effect and potential confounders (i.e. age, gender, Body Mass Index and Charnley's comorbidity classification as fixed effects. RESULTS: 586 THR patients and 400 TKR patients (40% of all eligible patients agreed to participate and completed all questionnaires sufficiently. We found no differences in HRQoL improvement in any dimension of the SF36 in THR patients. Patients with a higher completed level of schooling had a larger improvement in role-physical (9.38 points, 95%-CI:0.34-18.4, a larger improvement in general health (3.67 points, 95%-CI:0.56-6.79 and a smaller improvement in mental health (3.60 points, 95%-CI:0.82-6.38 after TKR. Postoperative patient satisfaction did not differ between different highest completed level of schooling groups. DISCUSSION: Completed level of schooling has no effect on the improvement in HRQoL and patient satisfaction in a Dutch THR population and a small effect in a similar TKR population. Undertreatment of patients with more disadvantaged Socio-Economic Position cannot be justified, given the similar

    The author shows how specific features of individual technologies have shaped a number of variables of concern to economists: the rate of productivity improvement, the nature of the learning process underlying technological change itself, the speed of technology transfer, and the effectiveness of government policies that are intended to influence technologies in particular ways. The separate chapters reflect a primary concern with some of the distinctive aspects of industrial technologies in the 20th Century, such as the increasing reliance upon science, but also the considerable subtlety and complexity of the dialectic between science and technology. Other concerns include the rapid growth in the development cost associated with new technologies as well as the difficulty of predicting the eventual performance characteristics of newly emerging technologies. 447 footnotes and references, 4 figures, 11 tables

    In China, the continuously increasing amount of municipal solid waste (MSW) has resulted in an urgent need for changing the current municipal solid waste management (MSWM) system based on mixed collection. A pilot program focusing on source-separated MSW collection was thus launched (2010) in Hangzhou, China, to lessen the related environmental loads. And greenhouse gas (GHG) emissions (Kyoto Protocol) are singled out in particular. This paper uses life cycle assessment modeling to evaluate the potential environmental improvement with regard to GHG emissions. The pre-existing MSWM system is assessed as baseline, while the source separation scenario is compared internally. Results show that 23 % GHG emissions can be decreased by source-separated collection compared with the base scenario. In addition, the use of composting and anaerobic digestion (AD) is suggested for further optimizing the management of food waste. 260.79, 82.21, and -86.21 thousand tonnes of GHG emissions are emitted from food waste landfill, composting, and AD, respectively, proving the emission reduction potential brought by advanced food waste treatment technologies. Realizing the fact, a modified MSWM system is proposed by taking AD as food waste substitution option, with additional 44 % GHG emissions saved than current source separation scenario. Moreover, a preliminary economic assessment is implemented. It is demonstrated that both source separation scenarios have a good cost reduction potential than mixed collection, with the proposed new system the most cost-effective one.

    [Purpose] The purpose of the present study was to investigate the relationship of health, sociodemographic, and economic factors and life satisfaction in young-old and old-old elderly groups. [Subjects and Methods] In the 2012 data from the Korean Longitudinal Study of Ageing, 4,134 of the final survey subjects aged 65 or older were analyzed. Multivaribale linear regression was performed to examine the degrees of explanatory power as factors (health, sociodemographic, and economic) in young-old (65 to 79 years) and old-old (80 years or older). [Results] Common variables that affected life satisfaction in both young-old and old-old subjects were health-related factors (depression, moderate to severe cognition, activities of daily living score), sociodemographic factors (level of education, familial communication, social activities), and economic factors (household assets, type of medical insurance). In the old-old group, age was an important associated factor. Mild cognitive impairment did not significantly affect life satisfaction in the old-old group, and only low-intensity social activities had an influence in the old-old group. [Conclusion] Difference in life satisfaction between the young-old and old-old elderly could be explained by gaps in the acceptance of the aging in health. Therefore, a personalized health consultation by life cycle could minimize these differences.

  3. Engendering economics.

    Science.gov (United States)

    1995-08-01

    Gender has become a major issue in discussions of economic development, with international organizations having generated studies which demonstrate that investments in women yield high returns in productivity, child health, and family welfare. Discussions of gender usually have been compartmentalized, with little impact upon broader studies of development. Examining the role that gender plays in economic life, however, could lead to a better understanding of the role which social institutions play in development. The author discusses reexamining gender bias and collective action by men and women with respect to property rights, family law, and the labor market. It is noted in closing that individual preferences are partially shaped by social norms which are strongly influenced by the coalitions which hold power in a society. As women gain collective power, they are likely to challenge the social norms which are costly to them.

    The catastrophic degradation of the Black Sea in a period of four decade has been the major concern of the Black Sea countries and international communities since Bucharest Convention signed in 1992. The Black Sea Region has became a challenging international arena for political scientific and socio-economic activities. Intensive international programmes and establishment of governmental and Non Governmental Organizational structures of the 1990s including Black Sea Economic Cooperation (BSEC), Black Sea Environmental Programme(BSEP), Environmental Programme for the Danube River Basin, Marine Environmental Assessment of the Black Sea Region Technical Cooperation Programme by the IAEA and establishment of the Black Sea Commission Permanent Secretariat are some of the major international efforts of the past decade that emphasizes the multi-nationality and large dimension of the Black Sea environmental management issues. The environmental degradation of the Black Sea is briefly reviewed based on the BSEP reports and data available for land based pollution sources. The environmental risk of marine vessel accidents are indicated and environmental safety concern is emphasized under the current conditions of intense energy transportation projects in the Black Sea and Caspian regions. The international policy actions, co-operation issues and scientific programmes of the past decade are overviewed with emphasis on the international achievements. Concluding remarks include the vital importance of continuation of the international commitments and sharing the political, scientific and socio-economic responsibility on the transboundary environmental pollution, rehabilitation and the safety issues of the Black Sea

    Full Text Available Background: The Center for Epidemiologic Studies Depression (CES-D scale is one of the most widely used tools to measure depressive symptoms in epidemiological studies. Given the importance of cross-racial measurement equivalence of CES-D scale for research, we performed confirmatory factor analysis of 12 - item CES-D in a nationally representative sample of Black and White adults in the United States.Methods: We used data from the National Survey of American Life (NSAL, 2001-2003. A total number of 3,570 Blacks (African Americans and 891 non-Hispanic Whites were included in the present study. Confirmatory factor analysis was carried out on the 12-item CES-D scale using multi-group structural equation modeling (SEM.Results: For both Blacks and Whites, best fitting model was found to be the 3-factor model, indicating invariance of factor structure between Blacks and Whites. Statistically different fit of the models with and without constraints indicated lack of invariance of factor loadings between Blacks and Whites. Some of the positive (i.e. as good, and hopeful and interpersonal (i.e. people were unfriendly items showed poor loadings, even in the 3- factor solution that allowed separate domains for positive affect, negative affect, and interpersonal problems. Despite the good fit of our final model, more items (i.e. as good, hopeful, keeping mind, and everything effort had poor loadings in Blacks than Whites (i.e. as good.Conclusion: There is invariance in factor structure but lack of invariance in factor/item loadings among Blacks and Whites. These findings have implications for cross-racial studies of depressive symptoms using CES-D among Blacks and Whites. Further research is warranted to scrutinize the role of socio-economics and culture in explaining lack of invariance of CES-D scale between Blacks and Whites.

    This study investigated the effect of socio-economic status (SES) on health-related quality of life (HRQoL) among persons with benign prostatic hyperplasia (BPH). The data were collected by way of surveying persons with BPH aged from 35 to 85 (937) and selected via random sample. The diagnosis was confirmed with the use of I-PSS questionnaires (8-19 points), OABq-AT (≥8 points) and daily urinations. A study on HRQoL was conducted using the SF-36 questionnaire. SES was evaluated using the patients' ambulance cards (F112U) and tax inspection documents with their written permission. Verification of the viability of the differences in the HRQoL level of patients with different SES was conducted in each age cohort using ANOVA. The goal of the multifactor regressive analysis using least weighted squares was identified as featuring the strongest relationships between SES and HRQoL. In comparing the average regression squares with average error squares, selection of the entry variables was conducted. Among persons with a BPH, the strongest relationship was discovered between profession, level of education, place of residence and HRQoL. A weaker relationship was identified between income and HRQoL, and there was no relationship between marital status and HRQoL. HRQoL among persons with a different level of SES figures aged 65+ proved homogeneous. We can expect HRQoL improvement among persons with BPH while increasing informedness on the possibilities for treating and improving help for workers of industrial and rural production residing in rural areas. © 2017 Blackwell Verlag GmbH.

    2014-04-01

    In the present study the relation between overweight/obesity and health-related quality of life (HRQoL) in adolescence is analysed. Of special interest is the question, to what extent this relation varies by socio-economic status (SES) and education. Data base is a subsample of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS, n = 6,813, 11-17 years). For the assessment of overweight and obesity, body mass index (BMI) was calculated based on standardised body height and weight measurements. The HRQoL was collected using the KINDL-R-questionnaire, which allows statements concerning a total rating as well as 6 dimensions: physical well-being, emotional well-being, self-worth, family well-being, well-being in relation to friends/peers and school well-being. SES and education are analysed as moderating factors. The results show that obese boys as well as overweight and obese girls have a diminished HRQoL compared to normal weight peers. The analyses according to SES and education suggest that in girls this finding applies for all considered subgroups. Thus, in girls neither SES nor education has a moderating impact on the relation between overweight/obesity and HRQoL. In boys, only SES has a moderating impact on the relation between overweight and HRQoL in favour of the low status group. In terms of the relation between obesity and HRQoL, in boys also only SES has a moderating impact on the analysed relation, but here in favour of the high status group. Altogether, the results show that overweight and especially obese adolescents are affected in their HRQoL, this being almost independent of SES and education. Interventions to improve the HRQoL of overweight and obese adolescents should be independent of SES and education.

    2017-09-01

    Full Text Available This study investigated whether Vincent van Gogh became increasingly self-focused—and thus vulnerable to depression—towards the end of his life, through a quantitative analysis of his written pronoun use over time. A change-point analysis was conducted on the time series formed by the pronoun use in Van Gogh’s letters. We used time as a predictor to see whether there was evidence for increased self-focus towards the end of Van Gogh’s life, and we compared this to the pattern in the letters written before his move to Arles. Specifically, we examined Van Gogh’s use of first person singular pronouns (FPSP and first person plural pronouns (FPPP in the 415 letters he wrote while working as an artist before his move to Arles, and in the next 248 letters he wrote after his move to Arles until his death in Auvers-sur-Oise. During the latter period, Van Gogh’s use of FPSP showed an annual increase of 0.68% (SE = 0.15, p < 0.001 and his use of FPPP showed an annual decrease of 0.23% (SE = 0.04, p < 0.001, indicating increasing self-focus and vulnerability to depression. This trend differed from Van Gogh’s pronoun use in the former period (which showed no significant trend in FPSP, and an annual increase of FPPP of 0.03%, SE = 0.02, p = 0.04. This study suggests that Van Gogh’s death was preceded by a gradually increasing self-focus and vulnerability to depression. It also illustrates how existing methods (i.e., quantitative linguistic analysis and change-point analysis can be combined to study specific research questions in innovative ways.

    This study investigated whether Vincent van Gogh became increasingly self-focused—and thus vulnerable to depression—towards the end of his life, through a quantitative analysis of his written pronoun use over time. A change-point analysis was conducted on the time series formed by the pronoun use in Van Gogh’s letters. We used time as a predictor to see whether there was evidence for increased self-focus towards the end of Van Gogh’s life, and we compared this to the pattern in the letters written before his move to Arles. Specifically, we examined Van Gogh’s use of first person singular pronouns (FPSP) and first person plural pronouns (FPPP) in the 415 letters he wrote while working as an artist before his move to Arles, and in the next 248 letters he wrote after his move to Arles until his death in Auvers-sur-Oise.

    Ecological Economics arise as a scientific discipline aimed to integrate concepts of economics, ecology, thermodynamics, ethic and other natural and social sciences in order to incorporate a biophysical and integrated perspective of the inter dependences between economies and environment, from a plural conception and a methodology beyond disciplines. Ecological Economics studies the black box of economic processes usually excluded of the traditional economics: thermodynamics and ecology. Although it is relatively a new field of study, it has been strengthening its theoretical framework with scientific basis and analytic principles that lead to its identification as a new discipline that show a whole new paradigm. The scope of this article is to show the conceptual and methodological bases, the main founders, approaches and central debates of this new discipline. This brief introduction is a preamble to the papers of the meeting Ecological Economics: a perspective for Colombia included in this number, that took place on September 22 - 27 of 2007, at the National University of Colombia at Bogota. During tree days national and international experts, professors, researchers, workers of environmental sector and people interested on environmental issues joined together to know the conceptual and methodological achievements reached of this discipline; as well as to analyse and evaluate the environmental problems of the country, from the systemic, interdisciplinary and general perspective that it promotes

    There is often large divergence in the effects of key nutrients on life span (LS) and reproduction in the sexes, yet nutrient intake is regulated in the same way in males and females given dietary choice. This suggests that the sexes are constrained from feeding to their sex-specific nutritional optima for these traits. Here, we examine the potential for intralocus sexual conflict (IASC) over optimal protein and carbohydrate intake for LS and reproduction to constrain the evolution of sex-specific nutrient regulation in the field cricket, Teleogryllus commodus. We show clear sex differences in the effects of protein and carbohydrate intake on LS and reproduction and strong positive genetic correlations between the sexes for the regulated intake of these nutrients. However, the between-sex additive genetic covariance matrix had very little effect on the predicted evolutionary response of nutrient regulation in the sexes. Thus, IASC appears unlikely to act as an evolutionary constraint on sex-specific nutrient regulation in T. commodus. This finding is supported by clear sexual dimorphism in the regulated intake of these nutrients under dietary choice. However, nutrient regulation did not coincide with the nutritional optima for LS or reproduction in either sex, suggesting that IASC is not completely resolved in T. commodus. © 2017 The Author(s).

    Methods and results of searching for stellar mass black holes in binary systems and for supermassive black holes in galactic nuclei of different types are described. As of now (June 2002), a total of 100 black hole candidates are known. All the necessary conditions Einstein's General Relativity imposes on the observational properties of black holes are satisfied for candidate objects available, thus further assuring the existence of black holes in the Universe. Prospects for obtaining sufficient criteria for reliably distinguishing candidate black holes from real black holes are discussed. (reviews of topical problems)

    1994-06-01

    Although the first chiropractic adjustment was given by D.D. Palmer to a black man in 1895, within two decades attendance at the Palmer School of Chiropractic was forbidden to blacks. Not until mid-century were blacks allowed entrance into the oldest and largest chiropractic college in the United states. Denied entry at the Palmer School, most blacks who entered chirporactic studied in "Jim Crow" schools run by white practitioners in the North. This paper explores the social, historicl and economic factors influencing the exclusion of blacks from medical education, and concludes that chirpractic education is at the stage medical education was twenty-five years ago in its attempts to recruit black students. The author recommends that the Association of Chiropractic Colleges establish a task force on minoritiy recruitment to expand the educational opportunities in chiropractic for blacks and other minorities.

    2007-01-01

    Five dimensional neutral rotating black rings are described from a Randall-Sundrum brane world perspective in the bulk black string framework. To this end we consider a rotating black string extension of a five dimensional black ring into the bulk of a six dimensional Randall-Sundrum brane world with a single four brane. The bulk solution intercepts the four brane in a five dimensional black ring with the usual curvature singularity on the brane. The bulk geodesics restricted to the plane of rotation of the black ring are constructed and their projections on the four brane match with the usual black ring geodesics restricted to the same plane. The asymptotic nature of the bulk geodesics are elucidated with reference to a bulk singularity at the AdS horizon. We further discuss the description of a brane world black ring as a limit of a boosted bulk black 2 brane with periodic identification

    Some of the country's highest rates of morbidity and mortality from cardiovascular disease are found in lower-income black communities in the rural Southeast. Research suggests these disparities originate in the early decades of life, and partly reflect the influence of broader socioeconomic forces acting on behavioral and biological processes that accelerate cardiovascular disease progression. However, this hypothesis has not been tested explicitly. Here, we examine metabolic syndrome (MetS) in rural black young adults as a function of their family's economic conditions before and after the Great Recession. In an ongoing prospective study, we followed 328 black youth from rural Georgia, who were 16 to 17 years old when the Great Recession began. When youth were 25, we assessed MetS prevalence using the International Diabetes Federation's guidelines. The sample's overall MetS prevalence was 18.6%, but rates varied depending on family economic trajectory from before to after the Great Recession. MetS prevalence was lowest (10.4%) among youth whose families maintained stable low-income conditions across the Recession. It was intermediate (21.8%) among downwardly mobile youth (ie, those whose families were lower income before the Recession, but slipped into poverty). The highest MetS rates (27.5%) were among youth whose families began the Recession in poverty, and sank into more meager conditions afterwards. The same patterns were observed with 3 alternative MetS definitions. These patterns suggest that broader economic forces shape cardiometabolic risk in young blacks, and may exacerbate disparities already present in this community. © 2017 The Authors.

  14. The Black Death in England.

    Science.gov (United States)

    Sloan, A W

    1981-04-25

    From 1348 to 1350 Europe was devastated by an epidemic of plague, called at the time the Great Mortality and later the Black Death. The epidemic reached southern Europe from the Middle East and spread northward, reaching England in June 1348. Contemporary descriptions leave no doubt of the diagnosis, but estimates of the mortality differ widely owing to lack of contemporary statistics; in England it was probably between one-third and one-half of the population. The Black Death and subsequent plague epidemics in the 14th century had marked social and economic effects, reduced the prestige of the Church and off the medical profession, and were a factor in the social unrest which led to the Renaissance of the Reformation.

    By analyzing the key properties of black holes from the point of view of quantum information, we derive a model-independent picture of black hole quantum computing. It has been noticed that this picture exhibits striking similarities with quantum critical condensates, allowing the use of a common language to describe quantum computing in both systems. We analyze such quantum computing by allowing coupling to external modes, under the condition that the external influence must be soft-enough in order not to offset the basic properties of the system. We derive model-independent bounds on some crucial time-scales, such as the times of gate operation, decoherence, maximal entanglement and total scrambling. We show that for black hole type quantum computers all these time-scales are of the order of the black hole half-life time. Furthermore, we construct explicitly a set of Hamiltonians that generates a universal set of quantum gates for the black hole type computer. We find that the gates work at maximal energy efficiency. Furthermore, we establish a fundamental bound on the complexity of quantum circuits encoded on these systems, and characterize the unitary operations that are implementable. It becomes apparent that the computational power is very limited due to the fact that the black hole life-time is of the same order of the gate operation time. As a consequence, it is impossible to retrieve its information, within the life-time of a black hole, by externally coupling to the black hole qubits. However, we show that, in principle, coupling to some of the internal degrees of freedom allows acquiring knowledge about the micro-state. Still, due to the trivial complexity of operations that can be performed, there is no time advantage over the collection of Hawking radiation and subsequent decoding.

    The aim of this study was to explore ethnic differences in the separate and additive effects of anxiety and depression on self-rated mental health (SRMH) of Blacks in the USA. With a cross-sectional design, we used data from a national household probability sample of African Americans (n = 3570) and Caribbean Blacks (n = 1621) who participated in the National Survey of American Life, 2001-2003. Demographic factors, socio-economic factors, 12-month general anxiety disorder (GAD) and major depressive disorder (MDD), and current SRMH were measured. In each ethnic group, three logistic regressions were used to assess the effects of GAD, MDD, and their combinations on SRMH. Among African Americans, GAD and MDD had separate effects on SRMH. Among Caribbean Blacks, only MDD but not GAD had separate effect on SRMH. Among African Americans, when the combined effects of GAD and MDD were tested, GAD but not MDD was associated with SRMH. The separate and additive effects of GAD and MDD on SRMH among Blacks depend on ethnicity. Although single-item SRMH measures are easy methods for the screening of mental health need, community-based programs that aim to meet the need for mental health services among Blacks in the USA should consider within-race ethnic differences in the applicability of such instruments.

Global economic crisis puts emphasis on limited possibilities of national governments in solving economic problems and general problems of society. Does it also mean that globalization and global economic crisis points out the need to think about new economic theory and new understanding of economics? In this paper I will argue that globalization reveals the need to change dominant economic paradigm - from traditional economic theory (mainstream with macroeconomic stability as the goal of economic policy, to the “quantum economics“, which is based on “economic quantum” and immanent to the increase of wealth (material and non-material of every individual in society and promoting set of values immanent to the wealth increase as the goal of economic policy.

    2009-01-01

    Macroscopic entropy of an extremal black hole is expected to be determined completely by its near horizon geometry. Thus two black holes with identical near horizon geometries should have identical macroscopic entropy, and the expected equality between macroscopic and microscopic entropies will then imply that they have identical degeneracies of microstates. An apparent counterexample is provided by the 4D-5D lift relating BMPV black hole to a four dimensional black hole. The two black holes have identical near horizon geometries but different microscopic spectrum. We suggest that this discrepancy can be accounted for by black hole hair - degrees of freedom living outside the horizon and contributing to the degeneracies. We identify these degrees of freedom for both the four and the five dimensional black holes and show that after their contributions are removed from the microscopic degeneracies of the respective systems, the result for the four and five dimensional black holes match exactly.

    Full Text Available The figure of the Black Arab as a form of guilt and sin is a well-established memorial pattern throughout the Mediterranean world, having already existed for more than 3000 years. This text is focused on two different types of interpretation of the Black Stone and its semantic relation with the symbolized figure of Black Arab in the oral traditions of Mediterranean peoples - Jewish religion and Islamic eschatology. The transformation of the signification of the Black Stone was transferred to the Islamic religion in the act of pilgrimage. The Jewish practice of transferring sin and guilt is related with the Iranian-Manichean Ahura Mazda-Ahriman, and the ancient Greek goddess Hecate. All manifestations of the Black Arab left a deep trace on Slavic spiritual life through the Slavic gods Chernobog, Triglav and Toyan and consequently on the deeply rooted conception of all Slavic peoples that the Black Arab was a black demon of death and the underworld.

    The study, using data from 801 11-16-year-olds clustered in 68 schools across England and Wales, tested whether closeness to grandparents moderates the association between contextual stress and adolescent psychopathology and prosocial behavior, measured with the strengths and difficulties questionnaire (SDQ). Contextual stress was measured at both school area level (assessed with the index of multiple deprivation) and child level (assessed, as life stress, with the number of proximal and distal adverse life events experienced). At baseline, area stress (multiple deprivation) was unrelated to psychopathology (SDQ), and although both proximal (during the last 12 months) and distal (before the last 12 months) life stress was associated with broad and specific child psychopathology, the association with proximal life stress was stronger. Closeness to the most significant grandparent moderated both the effect of proximal life stress on hyperactivity and broad psychopathology, and the effect of the interaction between distal and proximal life stress on broad and externalizing psychopathology. These findings suggest that the role of grandparents deserves further attention in future investigations of the development of resilience in youth.

    Oral health-related quality of life (OHRQoL) is an important patient-reported outcome measure in dental research. This study was conducted to analyse the association between OHRQoL, as measured using the five-item version of the Oral Health Impact Profile (OHIP-5), and different socio-economic indices. A national survey of randomly selected adult individuals in Sweden (n = 3,500) was performed using telephone interviews. The questions asked for the purpose of this study were defined by the items of the OHIP-5, just as questions were asked regarding socio-economic variables, including education, income, and economic resources. Poor OHRQoL, as identified by an OHIP-5 score of 3 or higher on at least two of the five items, was statistically significantly associated in multivariate analysis with low income (OR = 1.84) and having no economic resources (OR = 2.19). The statistical models were adjusted for age, gender, ethnicity, marital status, dental-care utilization, dental anxiety, and smoking. The OHIP-5 may be used in larger epidemiological surveys because it demonstrates the ability to discriminate for a range of important areas of measurement in dental public health, including social determinants. © 2017 Eur J Oral Sci.

It is through language that he decodes similes, metaphores and apostrophes out of clarity that trace our roots to our dark past which is from the eye of the beholder. Quincy's words bounce back at us with words of wisdom from the voice that humms in our head. Quincy maps his experience into beautiful shcemes of imprisoned thought. Quincy has mirrored a managerie of space on a blank page using pain and agony to slowly develop an illusion for movement. Quincy's sentex is the blues in space that echoes in the air in spoken tongues. It is from dreams we pulsate life through shared idioms of time. When we can identify in how sorrow has touched our lives, we believe in fear itself will keep us alive. Fear is an invisible ploom we live through rituals from desire. It is from this madness we imagine love is far deeper than fear itself.

    Recent work, which has been investigating the use of the concept of entropy with respect to gravitating systems, black holes and the universe as a whole, is discussed. The resulting theory of black holes assigns a finite temperature to them -about 10 -7 K for ordinary black holes of stellar mass -which is in complete agreement with thermodynamical concepts. It is also shown that black holes must continuously emit particles just like ordinary bodies which have a certain temperature. (U.K.)

    In low or middle income countries chronic diseases are rapidly becoming the main cause of disease burden. However, the main focus of health policymakers has been on preventing death from cancer and heart disease, with very little attention to the growing problem of long-term needs for care (dependence). Numbers of dependent older people are set to quadruple by 2050. The economic impact of providing long-term care is likely to be substantial. The study uses mixed methods and draws on and extends the population-based surveys conducted by the 10/66 Dementia Research Group. We focus on two countries in Latin America (Peru and Mexico), China and Nigeria. The surveys comprised baseline surveys of health, socioeconomic circumstances and care arrangements, repeated three to four years later. We are going back to these households to make a detailed assessment of the overall economic status and the use of health services by all family members. We will compare households where: a) an older resident became dependent between baseline and follow-up (incident care), b) one or more older people were dependent at both time points (chronic care), b) c) no older residents had needs for care (control households) for household income, consumption, healthcare expenditure and economic strain. In each of the four countries we are carrying out six detailed household 'case studies' to explore in more depth the economic impacts of dependence, and the social relations between household members and others in their network. The INDEP study will provide a detailed examination of the economic and social effects of care dependence in low and middle income settings. As the proportion of older people with needs for care rises rapidly in these countries, this neglected policy area is likely to become increasingly salient for families, communities and policymakers alike. Our detailed multilevel plans for dissemination will ensure that the study helps to put this important issue on the agenda for the

    Lower rates of substance abuse are found among Black Americans compared to Whites, but little is known about differences in substance abuse across ethnic groups within the black population. We examined prevalence rates of substance abuse among Blacks across three geographic regions (US, Jamaica, Guyana). The study also sought to ascertain whether length of time, national context and major depressive episodes (MDE) were associated with substance abuse. We utilized three different data sources based upon probability samples collected in three different countries. The samples included 3,570 African Americans and 1,621 US Caribbean Black adults from the 2001-2003 National Survey of American Life (NSAL). An additional 1,142 Guyanese Blacks and 1,176 Jamaican Blacks living in the Caribbean region were included from the 2005 NSAL replication extension study, Family Connections Across Generations and Nations (FCGN). Mental disorders were based upon DSM-IV criteria. For the analysis, we used descriptive statistics, chi-square, and multivariate logistic regression analytic procedures. Prevalence of substance abuse varied by national context, with higher rates among Blacks within the United States compared to the Caribbean region. Rates of substance abuse were lower overall for women, but differ across cohorts by nativity and length of time in the United States, and in association with major depressive episode. The study highlights the need for further examination of how substance abuse disparities between US-based and Caribbean-based populations may become manifested.

    Over hundred years has elapsed since the publication of "Operative Dentistry" (1908), a book by the famous odontologist and scientist Greene Vardiman Black. Throughout all his life Black worked hard on education, research, lecturing, publishing and teaching others. The innovator in many fields of dental medicine, particularly conservative therapy, he patented numerous inventions, implemented the standardization of instruments and procedures, constructed stomatological drills, gnathodynamometer, material hardness testing moulds, micrometer and microtome. Black is the author of more than 500 articles and innovations, as well as several exceptional books that are considered as classic within the domain of the dental literature, and which many generations were educated on. One can certainly say that Black occupies the honorary position among the eminent personalities of dental scientist as one of the founders of contemporary stomatology. If we take into consideration Black as to his merits in operative dentistry and wider, it could be confirmed that the epoch of contemporary dentistry could be divided into the era before Black, when many dental procedures were performed without scientific foundation, the time during Black when many dilemmas were resolved in operative dentistry branches backed up by laboratory investigations, and finally the homage period of the 20th century when the application of his postulates, instruments and conclusions were gradually being abandoned giving way to modern doctrines and materials due to the rapid advancement of industry of dental materials and operative techniques in modern stomatology all of which should be credited to the development of basic sciences.

    We study the problem of spatially stabilizing four dimensional extremal black holes in background electric/magnetic fields. Whilst looking for stationary stable solutions describing black holes placed in external fields we find that taking a continuum limit of Denef et al.'s multicenter supersymmetric black hole solutions provides a supergravity description of such backgrounds within which a black hole can be trapped within a confined volume. This construction is realized by solving for a levitating black hole over a magnetic dipole base. We comment on how such a construction is akin to a mechanical levitron.

  8. The angry black woman: the impact of pejorative stereotypes on psychotherapy with black women.

    Science.gov (United States)

    Ashley, Wendy

    2014-01-01

    In the aftermath of slavery and the resulting social, economic, and political effects, Black women have become the victims of negative stereotyping in mainstream American culture. Such stereotypes include the myth of the angry Black woman that characterizes these women as aggressive, ill tempered, illogical, overbearing, hostile, and ignorant without provocation. Symptoms presented by Black women during mental health treatment may reinforce this myth. However, many of the negative characteristics of the angry Black woman developed in response to external stressors and historical factors. Black women also have a unique experience with and expressions of anger that shape the presenting symptoms interpreted by the mental health clinician. This myth and corresponding negative stereotypes significantly affect Black women intrapsychically, interpersonally, and are likely to influence the efficacy of mental health treatment. Understanding and treatment of Black women in a mental health context should be influenced by the cultural norms and sociopolitical dynamics affecting these clients. Successful mental health treatment requires cultural competence and clinicians who are well prepared to navigate the inherent complexities of culture with clients. Awareness of the angry Black woman mythology, including its genesis, manifestations, and the unique experiences of Black women, may raise the standards of cultural competence for clinicians and provide more successful treatment outcomes in working with this population. A case example illustrates the assiduity essential to practicing in a culturally competent manner. A client is presented from a traditional psychotherapeutic perspective and then viewed through a lens that integrates psychotherapeutic practice with conscious awareness of the mythology and stereotypes impacting Black women. Implications for culturally relevant practice are discussed.

    Despite an increasing number of studies on the factors mediating the impact of the economic recession on mental health, research beyond the individual employment status is scarce. Our objectives were to investigate in which ways the mental health of employed and unemployed populations is differently affected by the current economic recession along the educational scale and to examine whether financial strain and social support explain these effects of the crisis. A repeated cross-sectional study, using two waves of the Andalusian Health Survey in 2007 (pre-crisis) and 2011-2012 (crisis). A population aged between 19 and 64 years was selected. The dependent variable was the Mental Component Summary of the SF-12 questionnaire. We performed Poisson regression models stratified by working status, with period, educational level, financial strain and social support as independent variables. We examined interactions between period and educational level. Age, sex, main earner, cohabitation and partner's working status were considered as covariates. The study included 3210 individuals (1185 women) in 2007 and 3633 individuals (1486 women) in 2011-2012. In working individuals the prevalence of poor mental health increased for secondary and complete primary studies groups during crisis compared to the pre-crisis period, while it decreased significantly in the university study group (PR = 0.76, 95% CI: 0.58-0.99). However, in unemployed individuals prevalence ratios for poor mental health increased significantly only in the secondary studies group (PR = 1.73, 95% CI: 1.06-2.83). Financial strain and social support yielded consistent associations with mental health in all subgroups. Only financial strain could partly explain the crisis effect on mental health among the unemployed. Our study supports the finding that current economic recession is associated with poorer mental health differentially according to labour market status and educational level. Those with secondary

  12. Causticizing for Black Liquor Gasifiers

    2009-01-07

    The cost-benefit outlook of black liquor gasification (BLG) could be greatly improved if the smelt causticization step could be achieved in situ during the gasification step. Or, at a minimum, the increase in causticizing load associated with BLG could be mitigated. A number of chemistries have been proven successful during black liquor combustion. In this project, three in situ causticizing processes (titanate, manganate, and borate) were evaluated under conditions suitable for high temperature entrained flow BLG, and low temperature steam reforming of black liquor. The evaluation included both thermodynamic modeling and lab experimentation. Titanate and manganate were tested for complete direct causticizing (to thus eliminate the lime cycle), and borates were evaluated for partial causticizing (to mitigate the load increase associated with BLG). Criteria included high carbonate conversion, corresponding hydroxide recovery upon hydrolysis, non process element (NPE) removal, and economics. Of the six cases (three chemistries at two BLG conditions), only two were found to be industrially viable: titanates for complete causticizing during high temperature BLG, and borates for partial causticizing during high temperature BLG. These two cases were evaluated for integration into a gasification-based recovery island. The Larsen [28] BLG cost-benefit study was used as a reference case for economic forecasting (i.e. a 1500 tpd pulp mill using BLG and upgrading the lime cycle). By comparison, using the titanate direct causticizing process yielded a net present value (NPV) of $25M over the NPV of BLG with conventional lime cycle. Using the existing lime cycle plus borate autocausticizing for extra capacity yielded a NPV of $16M.

  13. Black Edens, country Eves: Listening, performance, and black queer longing in country music.

    Science.gov (United States)

    Royster, Francesca T

    2017-07-03

    This article explores Black queer country music listening, performance, and fandom as a source of pleasure, nostalgia, and longing for Black listeners. Country music can be a space for alliance and community, as well as a way of accessing sometimes repressed cultural and personal histories of violence: lynching and other forms of racial terror, gender surveillance and disciplining, and continued racial and economic segregation. For many Black country music listeners and performers, the experience of being a closeted fan also fosters an experience of ideological hailing, as well as queer world-making. Royster suggests that through Black queer country music fandom and performance, fans construct risky and soulful identities. The article uses Tina Turner's solo album, Tina Turns the Country On! (1974) as an example of country music's power as a tool for resistance to racial, sexual, and class disciplining.

    A trial-based comparison of the use of resources, costs and quality of life outcomes of arthroscopic and open surgical management for rotator cuff tears in the United Kingdom NHS was performed using data from the United Kingdom Rotator Cuff Study (UKUFF) randomised controlled trial. Using data from 273 patients, healthcare-related use of resources, costs and quality-adjusted life years (QALYs) were estimated at 12 months and 24 months after surgery on an intention-to-treat basis with adjustment for covariates. Uncertainty about the incremental cost-effectiveness ratio for arthroscopic versus open management at 24 months of follow-up was incorporated using bootstrapping. Multiple imputation methods were used to deal with missing data. There were no significant differences between the arthroscopic and open groups in terms of total mean use and cost of resources or QALYs at any time post-operatively. Open management dominated arthroscopic management in 59.8% of bootstrapped cost and effect differences. The probability that arthroscopic management was cost-effective compared with open management at a willingness-to-pay threshold of £20 000 per QALY gained was 20.9%. There was no significant overall difference in the use or cost of resources or quality of life between arthroscopic and open management in the trial. There was uncertainty about which strategy was most cost-effective. Cite this article: Bone Joint J 2016;98-B:1648-55. ©2016 Gray et al.

  15. Methodological Issues Surrounding the Use of Baseline Health-Related Quality of Life Data to Inform Trial-Based Economic Evaluations of Interventions Within Emergency and Critical Care Settings: A Systematic Literature Review.

    Trial-based cost-utility analyses require health-related quality of life data that generate utility values in order to express health outcomes in terms of quality-adjusted life years (QALYs). Assessments of baseline health-related quality of life are problematic where trial participants are incapacitated or critically ill at the time of randomisation. This review aims to identify and critique methods for handling non-availability of baseline health-related quality of life data in trial-based cost-utility analyses within emergency and critical illness settings. A systematic literature review was conducted, following PRISMA guidelines, to identify trial-based cost-utility analyses of interventions within emergency and critical care settings. Databases searched included the National Institute for Health Research (NIHR) Journals Library (1991-July 2016), Cochrane Library (all years); National Health Service (NHS) Economic Evaluation Database (all years) and Ovid MEDLINE/Embase (without time restriction). Strategies employed to handle non-availability of baseline health-related quality of life data in final QALY estimations were identified and critiqued. A total of 4224 published reports were screened, 19 of which met the study inclusion criteria (mean trial size 1670): 14 (74 %) from the UK, four (21%) from other European countries and one (5%) from India. Twelve studies (63%) were based in emergency departments and seven (37%) in intensive care units. Only one study was able to elicit patient-reported health-related quality of life at baseline. To overcome the lack of baseline data when estimating QALYs, eight studies (42%) assigned a fixed utility weight corresponding to either death, an unconscious health state or a country-specific norm to patients at baseline, four (21%) ignored baseline utilities, three (16%) applied values from another study, one (5%) generated utility values via retrospective recall and one (5%) elicited utilities from experts.

  16. Does Black Socioeconomic Mobility Explain Recent Progress Toward Black-White Residential Integration?

    Science.gov (United States)

    Wagmiller, Robert L; Gage-Bouchard, Elizabeth; Karraker, Amelia

    2017-08-01

    Studies of racial residential segregation have found that black-white segregation in U.S. metropolitan areas has declined slowly but steadily since the early 1970s. As of this writing, black-white residential segregation in the United States is approximately 25 % lower than it was in 1970. To identify the sources of this decline, we used individual-level, geocoded data from the Panel Study of Income Dynamics (PSID) to compare the residential attainment of different cohorts of blacks. We analyzed these data using Blinder-Oaxaca regression decomposition techniques that partition the decline in residential segregation among cohorts into the decline resulting from (1) changes in the social and economic characteristics of blacks and (2) changes in the association between blacks' social and economic characteristics and the level of residential segregation they experience. Our findings show that black cohorts entering adulthood prior to the civil rights movement of the 1960s experienced consistently high levels of residential segregation at middle age, but that cohorts transitioning to adulthood during and after this period of racial progress experienced significantly lower levels of residential segregation. We find that the decline in black-white residential segregation for these later cohorts reflects both their greater social and economic attainment and a strengthening of the association between socioeconomic characteristics and residential segregation. Educational gains for the post-civil rights era cohorts and improved access to integrated neighborhoods for high school graduates and college attendees in these later cohorts were the principal source of improved residential integration over this period.

  18. Future electricity generation: An economic and environmental life cycle perspective on near-, mid- and long-term technology options and policy implications

    Science.gov (United States)

    Bergerson, Joule Andrea

    This thesis evaluates the cost and environmental tradeoffs of current and future electricity generation options from a life cycle perspective. Policy and technology options are considered for each critical time horizon (near-, mid-, and long-term). The framework developed for this analysis is a hybrid life cycle analysis which integrates several models and frameworks including process and input-output life cycle analysis, an integrated environmental control model, social costing, forecasting and future energy scenario analysis. The near-term analysis shows that several recent LCA studies of electricity options have contributed to our understanding of the technologies available and their relative environmental impacts. Several promising options could satisfy our electricity demands. Other options remain unproven or too costly to encourage investment in the near term but show promise for future use (e.g. photovoltaic, fuel cells). Public concerns could impede the use of some desirable technologies (e.g. hydro, nuclear). Finally, less tangible issues such as intermittency of some renewable technologies, social equity and visual and land use impacts, while difficult to quantify, must be considered in the investment decision process. In the mid-term analysis, this thesis explores alternative methods for transport of coal energy. A hybrid life cycle analysis is critical for evaluating the cost, efficiency and environmental tradeoffs of the entire system. If a small amount of additional coal is to be shipped, current rail infrastructure should be used where possible. If entirely new infrastructure is required, the mine mouth generation options are cheaper but have increased environmental impact due to the increased generation required to compensate for transmission line losses. Gasifying the coal to produce methane also shows promise in terms of lowering environmental emissions. The long-term analysis focuses on the implications of a high coal use future. This scenario

    2000-01-01

    We revisit the geometry representing l collinear Schwarzschild black holes. It is seen that the black holes' horizons are deformed by their mutual gravitational attraction. The geometry has a string like conical singularity that connects the holes but has nevertheless a well defined action. Using standard gravitational thermodynamics techniques we determine the free energy for two black holes at fixed temperature and distance, their entropy and mutual force. When the black holes are far apart the results agree with Newtonian gravity expectations. This analyses is generalized to the case of charged black holes. Then we consider black holes embedded in string/M-theory as bound states of branes. Using the effective string description of these bound states and for large separation we reproduce exactly the semi-classical result for the entropy, including the correction associated with the interaction between the holes

    This paper describes the incorporation of nanotextured black silicon as an optical absorbing material into silicon-based micro-optoelectromechanical systems devices to reduce stray light and increase optical contrast during imaging. Black silicon is created through a maskless dry etch process and characterized for two different etch conditions, a cold etch performed at 0°C and a cryogenic etch performed at -110°C. We measure specular reflection at visible wavelengths to be black velvet paint used to coat optical baffles and compare favorably with other methods to produce black surfaces from nanotextured silicon or using carbon nanotubes. We illustrate the use of this material by integrating a black silicon aperture around the perimeter of a deformable focus-control mirror. Imaging results show a significant improvement in contrast and image fidelity due to the effective reduction in stray light achieved with the self-aligned black aperture.

They cover general theoretical aspects of black hole astrophysics, the theory of accretion and ejection of gas and jets, stellar-sized black holes observed in the Milky Way, the formation and evolution of supermassive black holes in galactic centers and quasars as well as their influence on the dynamics in galactic nuclei. The final chapter addresses analytical relativity of black holes supporting theoretical understanding of the coalescence of black holes as well as being of great relevance in identifying gravitational wave signals. With its introductory chapters the book is aimed at advanced graduate and post-graduate students, but it will also be useful for specialists.

    We find a realization of linear electroelasticity theory in gravitational physics by uncovering a new response coefficient of charged black branes, exhibiting their piezoelectric behavior. Taking charged dilatonic black strings as an example and using the blackfold approach we measure their elastic and piezolectric moduli. We also use our results to draw predictions about the equilibrium condition of charged dilatonic black rings in dimensions higher than six.

    It is shown that there are large static black holes for which all curvature invariants are small near the event horizon, yet any object which falls in experiences enormous tidal forces outside the horizon. These black holes are charged and near extremality, and exist in a wide class of theories including string theory. The implications for cosmic censorship and the black hole information puzzle are discussed. copyright 1997 The American Physical Society

    We construct a four-dimensional BPS saturated heterotic string solution from the Taub-NUT solution. It is a nonextremal black hole solution since its Euler number is nonzero. We evaluate its black hole entropy semiclassically. We discuss the relation between the black hole entropy and the degeneracy of string states. The entropy of our string solution can be understood as the microscopic entropy which counts the elementary string states without any complications. copyright 1997 The American Physical Society

    Full Text Available En este trabajo pretendemos analizar los determinantes de la satisfacción con la vida de las personas extranjeras en España y las diferencias con las autóctonas. Las preguntas clave son las siguientes: ¿Es más infeliz la población extranjera que la autóctona? ¿Existen diferencias entre los distintos factores relacionados con la felicidad de ambas poblaciones? Los resultados indican que, controlando por variables económicas y sociales, los/as extranjeros/as están más insatisfechos/as que los/as autóctonos/as. Sin embargo, los resultados sugieren que el impacto de la crisis y las diferencias de ingresos condicionan la relación entre ser extranjero/a y la satisfacción con la vida. | In this research we analyze the determinants on life satisfaction of foreign people in Spain. The key questions we pose are as follows: Are foreign people more dissatisfied than Spaniards? Are there differences in the factors related to the life satisfaction of foreigners and Spaniards? The results indicate that, controlling for economic and social variables, foreigners are more dissatisfied than the native ones. However, the results suggest that the impact of the crisis, and income differences, condition the relationship between being foreign and satisfaction with life.

    Research literature suggests that burnout, depression, and a low mental quality of life (QOL) are common among health care workers. Economic crisis might have increased the burden of burnout, depression and low QOL in health care workers. To identify depression risk, burnout levels, and quality of life in a sample of workers of an Italian university hospital. Cross sectional study with comparison with two community surveys database results (n = 2000 and 1500, respectively). Overall, 522 workers accepted to take part in the study, representing a 78% response rate (out of 669 individuals). The frequency of positivity at the screener for Major Depressive Disorder among health care workers was more than double than that in the standardized community sample (33.3% vs 14.1%, pmedical staff, the highest risk was found in the surgeon units, while the lowest one was in the laboratories. Surgeons also were those most exposed to high risk of burnout, as measured by the Maslach Burnout Inventory. Since burnout is linked to patient safety and quality of patient care, and contribute to medical errors, dedicated interventions aimed at reducing poor mental health and low quality of life in medical staff are indicated.

    With the dawn of the new sustainable development goals, we face not only a world that has seen great successes in alleviating poverty but also a world that has left some groups, such as persons with disabilities, behind. Middle-income countries (MICs) are home to a growing number of persons with disabilities. As these countries strive to achieve the new goals, we have ample opportunity to include persons with disabilities in the emerging poverty alleviation strategies. However, a lack of data and research on the linkages between economic vulnerability and disability in MICs hampers our understanding of the factors increasing economic vulnerability in people with disabilities. This article aims to present data related to elements of this vulnerability in one MIC, South Africa. Focusing on out-of-pocket costs, it uses focus group discussions with 73 persons with disabilities and conventional content analysis to describe these costs. A complex and nuanced picture of disability-driven costs evolved on three different areas: care and support for survival and safety, accessibility of services and participation in community. Costs varied depending on care and support needs, accessibility (physical and financial), availability, and knowledge of services and assistive devices. The development of poverty alleviation and social protection mechanisms in MICs like South Africa needs to better consider diverse disability-related care and support needs not only to improve access to services such as education and health (National Health Insurance schemes, accessible clinics) but also to increase the effect of disability-specific benefits and employment equity policies.

  10. Malcolm X’s the ballot or the bullet speech? Its implications for Black Liberation Theology in present-day South Africa

    2015-05-01

    Full Text Available This article attempts to bring one of the greatest speeches of Malcolm X back to life in the current South Africa – the year 2015. It is a year of growing frustration and extreme dissatisfaction with basic living conditions amongst the greater part of black people in the country. Recounting the influences that Malcolm X had on Black Liberation Theology in South Africa, the article proposes that Black Liberation Theology in South Africa moves away from being an inward-looking critical theology to one that identifies with the basic concerns of the most vulnerable in society. It criticises both the political and the economic hegemonies that are currently perceived to perpetuate much of apartheid’s grave social ills in democratic South Africa. It calls attention to party politics that floods society with propaganda but in reality seems to have little real interest in the social well-being of the masses. In the article, the question as to what Malcolm X would have said about the current South African socio-economic context is asked. It is clear that both structural apartheid residues as well as the pure selfish interests of the current political rulers gang up against the chances of black people ever experiencing social justice in the near future.

    Understanding how human environments affect our health by "getting under the skin" and penetrating the cells, organs and physiological systems of our bodies is a key tenet in public health research. Here, we examine the idea that early life socioeconomic position (SEP) can be biologically embodied, potentially leading to the production of health inequalities across population groups. Allostatic load (AL), a composite measure of overall physiological wear-and-tear, could allow for a better understanding of the potential biological pathways playing a role in the construction of the social gradient in adult health. We investigate the factors mediating the link between two components of parental SEP, maternal education (ME) and parental occupation (PO), and AL at 44 years. Data was used from 7573 members of the 1958 British birth cohort follow-up to age 44. AL was constructed using 14 biomarkers representing four physiological systems. We assessed the contribution of financial/materialist, psychological/psychosocial, educational, and health behaviors/BMI pathways over the life course, in mediating the associations between ME, PO and AL. ME and PO were mediated by three pathways: educational, material/financial, and health behaviors, for both men and women. A better understanding of embodiment processes leading to disease development may contribute to developing adapted public policies aiming to reduce health inequalities. Copyright © 2016.

  12. The literature of the California black rail

    Few birds have remained so little known as the California black rail (Laterallus jamaicensis coturniculus). Although first collected in 1859 or before and reported in 1874 (Ridgway 1874), its life history, distribution, and status have remained so obscure that even a sight record of the bird is deemed worthy of a report in some ornithological publications. Because degradation and loss of freshwater and saltwater marshlands in California may be detrimentally affecting the black rail, both the U.S. Bureau of Sport Fisheries and Wildlife (1973) and the California Department of Fish and Game (1972) have classified it as rare and worthy of further study. The 84 papers and notes both summarized in this report and included in its bibliography include essentially all that is currently known about the California black rail. Only 11 of these papers consider the life history of this rail in any detail. The rest are distribution notes and some of the more important papers on the closely related eastern black rail (L. j. jamaicensis). The latter are included for comparative purposes, or because they may lend clues to currently unknown facets of the life history of the western race.

    Full Text Available Background: Black spots are a major problem in commercial shrimp species and can have negative effects on shrimps' appearance, quality, shelf life, economic value, and product acceptance by consumers. This study was conducted to investigate the effect of orange peel extract on chemical and sensory qualities as well as black spots on Litopenaeus vannamei species of white farmed shrimp. Methods: Samples included treated shrimps at concentration of 150 g, orange peel extract for 30 minutes, and control shrimps. After storage for 10 days at 1 ± 4 °C, the samples’ chemical and sensory evaluations were performed with an interval of 5 days. Results: pH factors, peroxide value, and total volatile network (TVN of treated samples were significantly lower compared to those of the control samples (P < 0.05. There was no significant difference in the moisture content. Black spots did not appear in the treated sample until the end of refrigerated storage, but melanosis appeared in control shrimp 5 days after storage. Conclusion: The results showed that because of having antioxidant and antimicrobial activity, orange peel extract improved shrimps' chemical and sensory qualities and reduced their black spots in the refrigerator temperature.

    The University of Missouri-Rolla will identify materials that will permit the safe, reliable and economical operation of combined cycle gasifiers by the pulp and paper industry. The primary emphasis of this project will be to resolve the material problems encountered during the operation of low-pressure high-temperature (LPHT) and low-pressure low-temperature (LPLT) gasifiers while simultaneously understanding the materials barriers to the successful demonstration of high-pressure high-temperature (HPHT) black liquor gasifiers. This study will define the chemical, thermal and physical conditions in current and proposed gasifier designs and then modify existing materials and develop new materials to successfully meet the formidable material challenges. Resolving the material challenges of black liquor gasification combined cycle technology will provide energy, environmental, and economic benefits that include higher thermal efficiencies, up to three times greater electrical output per unit of fuel, and lower emissions. In the near term, adoption of this technology will allow the pulp and paper industry greater capital effectiveness and flexibility, as gasifiers are added to increase mill capacity. In the long term, combined-cycle gasification will lessen the industry's environmental impact while increasing its potential for energy production, allowing the production of all the mill's heat and power needs along with surplus electricity being returned to the grid. An added benefit will be the potential elimination of the possibility of smelt-water explosions, which constitute an important safety concern wherever conventional Tomlinson recovery boilers are operated. Developing cost-effective materials with improved performance in gasifier environments may be the best answer to the material challenges presented by black liquor gasification. Refractory materials may be selected/developed that either react with the gasifier environment to form protective

    Applying Einstein's theory of gravitation to black holes and their interactions with their surroundings leads to the conclusion that the sum of the surface areas of several black holes can never become less. This is shown to be analogous to entropy in thermodynamics, and the term entropy is also thus applied to black holes. Continuing, expressions are found for the temperature of a black hole and its luminosity. Thermal radiation is shown to lead to explosion of the black hole. Numerical examples are discussed involving the temperature, the mass, the luminosity and the lifetime of black mini-holes. It is pointed out that no explosions corresponding to the prediction have been observed. It is also shown that the principle of conservation of leptons and baryons is broken by hot black holes, but that this need not be a problem. The related concept of instantons is cited. It is thought that understanding of thermal radiation from black holes may be important for the development of a quantified gravitation theory. (JIW)
