There has been increasing interest on the role of private foundations in education finance and delivery. We argue that this is due to a macro-policy context of stagnating levels of official development assistance for education and an uncritical acceptance of a logic of neutrality and the efficiency and effectiveness of of partnerships and…

Group-Wise Herding Behavior in Financial Markets: An Agent-Based Modeling Approach

PubMed Central

Kim, Minsung; Kim, Minki

2014-01-01

In this paper, we shed light on the dynamic characteristics of rational group behaviors and the relationship between monetary policy and economic units in the financial market by using an agent-based model (ABM), the Hurst exponent, and the Shannon entropy. First, an agent-based model is used to analyze the characteristics of the group behaviors at different levels of irrationality. Second, the Hurst exponent is applied to analyze the characteristics of the trend-following irrationality group. Third, the Shannon entropy is used to analyze the randomness and unpredictability of group behavior. We show that in a system that focuses on macro-monetary policy, steep fluctuations occur, meaning that the medium-level irrationality group has the highest Hurst exponent and Shannon entropy among all of the groups. However, in a system that focuses on micro-monetary policy, all group behaviors follow a stable trend, and the medium irrationality group thus remains stable, too. Likewise, in a system that focuses on both micro- and macro-monetary policies, all groups tend to be stable. Consequently, we find that group behavior varies across economic units at each irrationality level for micro- and macro-monetary policy in the financial market. Together, these findings offer key insights into monetary policy. PMID:24714635

The effects of macro-level interventions on addictive behavior.

PubMed

Pacula, R L; Chaloupka, F J

2001-12-01

Drug addictions are often viewed as compulsive behaviors, not sensitive to the typical rules of self-discipline or market forces. Nonetheless, many governments try to discourage consumption of addictive substances through macro policy tools, such as taxation, regulation and prohibition, in an effort to reduce the harmful consequences that result from their consumption. The government's ability to discourage this type of behavior through these macro policies depends critically on the responsiveness of addictive consumption to market interventions. This paper reviews the growing literature that applies economic principles to the analysis of "substance abuse." Specifically, we review the impact of prices and public policies on the demands for tobacco, alcohol, and illicit drugs. The findings from these studies clearly demonstrate that even addictive behaviors are sensitive to changes in the price of substances being abused. When the full price of the addictive good rises, consumption of that good falls, even among abusers. Therefore, public policies that raise the full price of a drug to a consumer, particularly youth, are likely to result in long run reductions in rates of addiction.

Getting the big picture: the macro-politics of information system development (and failure) in a Canadian hospital.

PubMed

Balka, E

2003-01-01

While recognized that global actors influence health information system design, studies of health informatics have largely focused on micro politics of technology design and implementation. Here a problematic patient care information system (PCIS) is discussed in relation to federal and provincial policies and corporate strategies to demonstrate that our understanding of health informatics can be enhanced by linking micro studies of health informatics to larger macro contexts. Interviews and document study. Although the extent to which federal initiatives influenced (or failed to influence) provincial and hospital initiatives remains debateable, events initiated at one level (the hospital's decision to implement software, initiated at the organizational level) are influenced (perhaps indirectly) by developments in other contexts (federal/macro changes gave an initiative more weight; provincial initiatives such as the Labour Accord altered the industrial relations environment in which system development occurred). Micro-studies of work practice, invaluable in addressing interactions between technologies, users and work practices, often fail to account for the historic reach of global actors, although it is often these historic circumstances that contribute to present-day interactions between user, information system and organization, and that find expression - often indirectly - in daily work practices.

Macro Trends and the Future of Public Health Practice.

PubMed

Erwin, Paul Campbell; Brownson, Ross C

2017-03-20

Public health practice in the twenty-first century is in a state of significant flux. Several macro trends are impacting the current practice of governmental public health and will likely have effects for many years to come. These macro trends are described as forces of change, which are changes that affect the context in which the community and its public health system operate. This article focuses on seven such forces of change: the Patient Protection and Affordable Care Act, public health agency accreditation, climate change, health in all policies, social media and informatics, demographic transitions, and globalized travel. Following the description of each of these, this article then turns to possible approaches to measuring, tracking, and understanding the impact of these forces of change on public health practice, including the use of evidence-based public health, practice-based research, and policy surveillance.

Macro-environmental factors associated with leisure-time physical activity: a cross-national analysis of EU countries.

PubMed

Van Tuyckom, Charlotte

2011-06-01

Although there is a growing agreement among researchers that the modern environment contributes to the current trend of decreasing leisure-time physical activity (LTPA), there are very few studies addressing environmental and policy correlates of LTPA within a cross-national European context. This study describes LTPA patterns across the European Union and identifies some macro-environmental factors associated with LTPA rates at a national level. Data on LTPA and indicators of the economic, physical, and policy environment were assembled from international databases for the 27 European member states. To examine the association of each of the independent macro-environmental variables and LTPA as a continuous dependent variable, bivariate linear regression models were employed. Separate analyses were done for the overall, male, and female groups. With respect to LTPA, striking differences between European member states and genders were found, with higher rates in Western and Northern European countries, and among males. Statistical significant associations were observed between overall LTPA and variables from the economic (GDP, real GDP, and public expenditures on health), food (available fat, available fruit, and vegetables), urbanisation (urban population, total and new passenger cars), and policy (all governance indicators) domains. Associations for male and female LTPA were similar, except that for males available fruit and vegetables, and for females available fat and urban population were not significant. This exploratory study seeks to plead for the need for cross-nationally comparable LTPA data and more sophisticated research in order to understand the role of macro-economic environments, with a special focus on policy-related variables and gender-specific differences.

[Heath and political regimes: presidential or parliamentary government for Colombia?].

PubMed

Idrovo, Alvaro J

2007-01-01

Changing the presidential regime for a parliamentarian one is currently be-ing discussed in Colombia. This preliminary study explores the potential effects on health of both presidential and parliamentary regimes by using world-wide data. An ecological study was undertaken using countries from which comparable information concerning life-expectancy at birth, political regime, economic development, inequality in income, social capital (as measured by general-ised trust or Corruption Perceptions Index), political rights, civil freedom and cultural diversity could be obtained. Life-expectancy at birth and macro-determinants were compared between both political regimes. The co-relationship between these macro-determinants was estimated and the relationship between political regimen and life-expectancy at birth was estimated using robust regression. Crude analysis revealed that parliamentary countries have greater life-expectancy at birth than countries having a presidential regime. Significant co-relationships between all macro-determinants were observed. No differential effects were observed between both political regimes regarding life-expectancy at birth in multiple robust regressions. There is no evidence that presidential or parliamentary regimes provide greater levels of health for the population. It is suggested that public health policies be focused on other macro-determinants having more known effects on health, such as income inequality.

'Time is costly': modelling the macroeconomic impact of scaling-up antiretroviral treatment in sub-Saharan Africa.

Ventelou, Bruno; Moatti, Jean-Paul; Videau, Yann; Kazatchkine, Michel

2008-01-02

Macroeconomic policy requirements may limit the capacity of national and international policy-makers to allocate sufficient resources for scaling-up access to HIV care and treatment in developing countries. An endogenous growth model, which takes into account the evolution of society's human capital, was used to assess the macroeconomic impact of policies aimed at scaling-up access to HIV/AIDS treatment in six African countries (Angola, Benin, Cameroon, Central African Republic, Ivory Coast and Zimbabwe). The model results showed that scaling-up access to treatment in the affected population would limit gross domestic product losses due to AIDS although differently from country to country. In our simulated scenarios of access to antiretroviral therapy, only 10.3% of the AIDS shock is counterbalanced in Zimbabwe, against 85.2% in Angola and even 100.0% in Benin (a total recovery). For four out of the six countries (Angola, Benin, Cameroon, Ivory Coast), the macro-economic gains of scaling-up would become potentially superior to its associated costs in 2010. Despite the variability of HIV prevalence rates between countries, macro-economic estimates strongly suggest that a massive investment in scaling-up access to HIV treatment may efficiently counteract the detrimental long-term impact of the HIV pandemic on economic growth, to the extent that the AIDS shock has not already driven the economy beyond an irreversible 'no-development epidemiological trap'.

Adapting to social and political transitions - the influence of history on health policy formation in the Republic of the Union of Myanmar (Burma).

2014-04-01

The Republic of the Union of Myanmar (Burma) has a long and complex history characterized by internal conflict and tense international relations. Post-independence, the health sector has gradually evolved, but with health service development and indicators lagging well behind regional expectations. In recent years, the country has initiated political reforms and a reorientation of development policy towards social sector investment. In this study, from a systems and historical perspective, we used publicly available data sources and grey literature to describe and analyze links between health policy and history from the post-independence period up until 2012. Three major periods are discernable in post war health system development and political history in Myanmar. The first post-independence period was associated with the development of the primary health care system extending up to the 1988 political events. The second period is from 1988 to 2005, when the country launched a free market economic model and was arguably experiencing its highest levels of international isolation as well as very low levels of national health investment. The third period (2005-2012) represents the first attempts at health reform and recovery, linked to emerging trends in national political reform and international politics. Based on the most recent period of macro-political reform, the central state is set to transition from a direct implementer of a command and control management system, towards stewardship of a significantly more complex and decentralized administrative order. Historical analysis demonstrates the extent to which these periodic shifts in the macro-political and economic order acts to reset the parameters for health policy making. This case demonstrates important lessons for other countries in transition by highlighting the extent to which analysis of political history can be instructive for determination of more feasible boundaries for future health policy action.

Fertility transitions and schooling: from micro- to macro-level associations.

PubMed

Eloundou-Enyegue, Parfait M; Giroux, Sarah C

2012-11-01

Research on the schooling implications of fertility transitions often faces an aggregation problem: despite policy interest in macro-level outcomes, empirical studies usually focus on the micro-level effects of sibsize on schooling. This article proposes an aggregation framework for moving from micro- to macro-level associations between fertility and schooling. The proposed framework is an improvement over previous aggregation methods in that it considers concurrent changes in the effects of sibsize, socioeconomic context, and family structure. The framework is illustrated with data from six sub-Saharan countries. Possible extensions are discussed.

2015-07-21

Current literature systematically reports that interventions to attract and retain health workers in underserved areas need to be context specific but rarely defines what that means. In this systematic review, we try to summarize and analyse context factors influencing the implementation of interventions to attract and retain rural health workers. We searched online databases, relevant websites and reference lists of selected literature to identify studies on compulsory rural service programmes and financial incentives. Forty studies were selected. Information regarding context factors at macro, meso and micro levels was extracted and synthesized. Macro-level context factors include political, economic and social factors. Meso-level factors include health system factors such as maldistribution of health workers, growing private sector, decentralization and health financing. Micro-level factors refer to the policy implementation process including funding sources, administrative agency, legislation process, monitoring and evaluation. Macro-, meso- and micro-level context factors can play different roles in agenda setting, policy formulation and implementation of health interventions to attract and retain rural health workers. These factors should be systematically considered in the different stages of policy process and evaluation.

Prevention of mental and behavioural disorders: implications for policy and practice.

Saxena, Shekhar; Jané-Llopis, Eva; Hosman, Clemens

2006-02-01

There is sufficient evidence indicating the efficacy of interventions in reducing risk factors, increasing protective factors, preventing psychiatric symptoms and new cases of mental disorders. Macro-policy interventions to improve nutrition, housing and education or to reduce economic insecurity have proven to reduce mental health problems. Specific interventions to increase resilience in children and adolescents through parenting and early interventions, and programmes for children at risk for mental disorders such as those who have a mentally ill parent or have suffered parental loss or family disruption, have also shown to increase mental well-being and decrease depressive symptoms and the onset of depressive disorders. Interventions for the adult population, from macro-policy strategies, such as taxation of alcohol products or workplace legislation, to individual support for those with signs of a mental disorder, can reduce mental health problems and associated social and economic burdens. Exercise, social support or community participation have also shown to improve mental health of older populations. Public mental health will benefit from continuing building the evidence base through combining different evaluation methods across low, middle and high income countries. The translation of evidence into policy and practice calls for action at the international, national and local level, including building capacity, advocacy, mainstreaming mental health into public health and other policies and securing infrastructures and sustainability. Mental health professionals have an important role to play in improving the evidence on prevention and promotion in mental health, in engaging relevant stakeholders for developing programmes, and as professional care providers in their practice.

2016-09-01

This study explored pre-service secondary science teachers' perceptions of classroom emotional climate in the context of the Bhutanese macro-social policy of Gross National Happiness. Drawing upon sociological perspectives of human emotions and using Interaction Ritual Theory this study investigated how pre-service science teachers may be supported in their professional development. It was a multi-method study involving video and audio recordings of teaching episodes supported by interviews and the researcher's diary. Students also registered their perceptions of the emotional climate of their classroom at 3-minute intervals using audience response technology. In this way, emotional events were identified for video analysis. The findings of this study highlighted that the activities pre-service teachers engaged in matter to them. Positive emotional climate was identified in activities involving students' presentations using video clips and models, coteaching, and interactive whole class discussions. Decreases in emotional climate were identified during formal lectures and when unprepared presenters led presentations. Emotions such as frustration and disappointment characterized classes with negative emotional climate. The enabling conditions to sustain a positive emotional climate are identified. Implications for sustaining macro-social policy about Gross National Happiness are considered in light of the climate that develops in science teacher education classes.

State planning plays a central role in Malaysia's social and economic development. The government's rural development policies are designed to promote agricultural incomes and help counterbalance ethnic inequalities. The Federal Land Development Authority (FELDA) implements one of the internationally most successful land development and resettlement programs. In this article, we quantify the impact of FELDA settlements on local out-migration rates, linking macro and micro approaches and using data from the Malaysian Family Life Survey, national censuses, and other sources. A model of instantaneous migration rates specifies an individual's migration rate as a function of individual-level sociodemographic characteristics, the level of urbanization of the origin and destination, and the extent of rural development at the district of current residence. Our results show that in the late 1960s and early 1970s, the existence of rural development centers in a district reduced the levels of out-migration to pre-1965 levels.

As one of the basic means of national macro-control, the tax policy is the major countermeasure that cannot be ignored in the prevention and control of air pollution. Studying the tax policy of prevention and control of air pollution will help to effectively control air pollution, develop a green economy and recycle economy and achieve the goal of improving environmental quality.

Being regarded as a problem of global dimensions, marine litter has been a growing concern that affects human beings, wildlife and the economic health of coastal communities to varying degrees. Due to its involvement with human behavior, marine littering has been regarded as a cultural matter encompassing macro and micro level aspects. At the micro or individual level, behavior and behavioral motivation of an individual are driven by perception of that person while at the macro or societal level, aspects including policies and legislations influence behavior. This paper investigates marine littering through the macro-micro level lenses in order to analyze and recommend how anti-littering behavior can be improved and sustained. Using Coleman's model of micro-macro relations, research questions are formulated and investigated through a social survey. Results showed important differences in perceptions among participating groups and to address key issues, potential actions are proposed along with a framework to sustain anti-littering behavior.

2013-04-01

The effect on public policy of macro to nano aspects of the deadliest Illness known to mankind is given. The focus is on the important role of physics which has been ignored so far to solve its problems. It is now acknowledged that the deadliest illness is actually a group of illnesses which are lumped together as mental illnesses. They are the most widespread and damaging illnesses in the world. Their impact on the entire society globally is huge because they afflict majority of the people irrespective of race, religion, sex, age, education and economic status. In USA alone, the number afflicted according to the official count is about 80 million (out of a total population of 315 million), and it is projected to increase to about 25 to 30% of the population within two decades. A model is given in this paper to address some of the key issues from macro to nano aspects of the deadliest illness. The information given in this paper is scientific though easy to understand. It will help the elected policy makers, public, physicists, neuroscientists, doctors, and care giving personnel world wide. The model explains the missing links in the diagnosis and treatment of mental illnesses. Additional evidence from other recent studies shall also be given.

The provision of institutional long-term care for older people varies across Europe reflecting different models of health care delivery. Care for dying residents requires integration of palliative care into current care work, but little is known internationally of the different ways in which palliative care is being implemented in the care home setting. To identify and classify, using a new typology, the variety of different strategic, operational, and organizational activities related to palliative care implementation in care homes across Europe. We undertook a mapping exercise in 29 European countries, using 2 methods of data collection: (1) a survey of country informants, and (2) a review of data from publically available secondary data sources and published research. Through a descriptive and thematic analysis of the survey data, we identified factors that contribute to the development and implementation of palliative care into care homes at different structural levels. From these data, a typology of palliative care implementation for the care home sector was developed and applied to the countries surveyed. We identified 3 levels of palliative care implementation in care homes: macro (national/regional policy, legislation, financial and regulatory drivers), meso (implementation activities, such as education, tools/frameworks, service models, and research), and micro (palliative care service delivery). This typology was applied to data collected from 29 European countries and demonstrates the diversity of palliative care implementation activity across Europe with respect to the scope, type of development, and means of provision. We found that macro and meso factors at 2 levels shape palliative care implementation and provision in care homes at the micro organizational level. Implementation at the meso and micro levels is supported by macro-level engagement, but can happen with limited macro strategic drivers. Ensuring the delivery of consistent and high-quality palliative care in care homes is supported by implementation activity at these 3 levels. Understanding where each country is in terms of activity at these 3 levels (macro, meso, and micro) will allow strategic focus on future implementation work in each country.

The development of Tobacco Harm Prevention Law in Vietnam: stakeholder tensions over tobacco control legislation in a state owned industry

PubMed Central

2011-01-01

Background Building on its National Tobacco Control Policy initiated in 2000, Vietnam is currently considering introducing a comprehensive law to strengthen the implementation of tobacco control policy. This study analyses the positions of key stakeholders in the development of tobacco control legislation in the context of a largely state-owned industry, and discusses their implications for the policy process. Methods Several qualitative methods were employed for the study including: literature review and documentary analysis; key informant interview; focus groups discussion; and key stakeholders survey. Findings The Ministry of Health, Ministry of Trade and Industry, and Ministry of Finance are key players in the tobacco control policy and legislation, representing competing bureaucratic interests over health, macro-economy and revenue. High-ranking officials, including the Communist Party and National Assembly members, take a rather relaxed position reflecting the low political stakes placed on tobacco issues. The state-owned tobacco industry is regarded as an important contributor to the government revenue and gross domestic product, and the relative weight on health and socioeconomic issues placed by stakeholders determine their positions on tobacco control. Overall, short-term economic interests have more immediate influence in setting policy directions, with the consequences of health gains perceived as relegated to a distant future. This was reflected in the position of tobacco control advocates, including MOH, that presented with reluctance in insisting on some tobacco control strategies revealing a mixture attitude of concessions to the socioeconomic uncertainties and a sense of bargaining to win the strategies that are more likely to be accepted. Conclusion The state-ownership of tobacco industry poses a major paradox within the government that benefits from manufacturing of tobacco products and is also responsible for controlling tobacco consumption. The perceptions of negative implications on government revenue and the macro-economy, coupled with the reluctance to challenge these issues from health perspective too directly, means that tobacco control has yet to secure itself a place on the priority policy agenda. The overall policy environment will shift in favour of tobacco control only if the economic framing can be challenged. PMID:21923945

Understanding the flows of people moving through the built environment is a vital source of information for the planners and policy makers who shape our cities. Smart phone applications enable people to trace themselves through the city and these data can potentially be then aggregated and visualised to show hot spots and trajectories of macro urban movement. In this paper our aim is to develop procedures for cleaning, aggregating and visualising human movement data and translating this into policy relevant information. In conducting this research we explore using bicycle data collected from a smart phone application known as RiderLog. We focus on the RiderLog application initially in the context of Sydney, Australia and discuss the procedures and challenges in processing and cleaning this data before any analysis can be made. We then present some preliminary map results using the CartoDB online mapping platform where data are aggregated and visualised to show hot spots and trajectories of macro urban movement. We conclude the paper by highlighting some of the key challenges in working with such data and outline some next steps in processing the data and conducting higher volume and more extensive analysis.

Social Action among Social Work Practitioners: Examining the Micro-Macro Divide.

PubMed

Mattocks, Nicole Olivia

2018-01-01

Social work is a profession that seeks to enhance the well-being of all people and promote social justice and social change through a range of activities, such as direct practice, community organizing, social and political action, and policy development. However, the current literature suggests that the profession's focus on social justice and social action are weakening, replaced by individualism and therapeutic interventions. This article examines data derived from a survey of 188 National Association of Social Workers members from Maryland; Virginia; and Washington, DC, to explore levels of social action participation among social workers and determine whether identifying as a macro-level practitioner would predict higher levels of social action activity compared with being a micro-level practitioner. Findings indicate that social workers in this sample engage in only a moderate level of social action behavior. In addition, identifying oneself as a mezzo- or macro-level practitioner predicts increased frequency of social action behavior. Implications include emphasizing the importance of social action in schools of social work and practice settings and adequately preparing social work professionals to engage in social action. © 2017 National Association of Social Workers.

Changing household responses to drought in Tharaka, Kenya: vulnerability, persistence and challenge.

PubMed

Smucker, Thomas A; Wisner, Ben

2008-06-01

Drought is a recurring challenge to the livelihoods of those living in Tharaka District, Kenya, situated in the semi-arid zone to the east of Mount Kenya, from the lowest slopes of the mountain to the banks of the Tana River. This part of Kenya has been marginal to the economic and political life of Kenya from the colonial period until the present day. A study of more than 30 years of change in how people in Tharaka cope with drought reveals resilience in the face of major macro-level transformations, which include privatisation of landownership, population growth, political decentralisation, increased conflict over natural resources, different market conditions, and environmental shifts. However, the study also shows troubling signs of increased use of drought responses that are incompatible with long-term agrarian livelihoods. Government policy needs to address the challenge of drought under these new macro conditions if sustainable human development is to be achieved.

Comparative analysis of zonal systems for macro-level crash modeling.

Cai, Qing; Abdel-Aty, Mohamed; Lee, Jaeyoung; Eluru, Naveen

2017-06-01

Macro-level traffic safety analysis has been undertaken at different spatial configurations. However, clear guidelines for the appropriate zonal system selection for safety analysis are unavailable. In this study, a comparative analysis was conducted to determine the optimal zonal system for macroscopic crash modeling considering census tracts (CTs), state-wide traffic analysis zones (STAZs), and a newly developed traffic-related zone system labeled traffic analysis districts (TADs). Poisson lognormal models for three crash types (i.e., total, severe, and non-motorized mode crashes) are developed based on the three zonal systems without and with consideration of spatial autocorrelation. The study proposes a method to compare the modeling performance of the three types of geographic units at different spatial configurations through a grid based framework. Specifically, the study region is partitioned to grids of various sizes and the model prediction accuracy of the various macro models is considered within these grids of various sizes. These model comparison results for all crash types indicated that the models based on TADs consistently offer a better performance compared to the others. Besides, the models considering spatial autocorrelation outperform the ones that do not consider it. Based on the modeling results and motivation for developing the different zonal systems, it is recommended using CTs for socio-demographic data collection, employing TAZs for transportation demand forecasting, and adopting TADs for transportation safety planning. The findings from this study can help practitioners select appropriate zonal systems for traffic crash modeling, which leads to develop more efficient policies to enhance transportation safety.

Practices influenced by policy? An exploration of newly hired science teachers at sites in South Africa and the United States

Navy, S. L.; Luft, J. A.; Toerien, R.; Hewson, P. W.

2018-05-01

In many parts of the world, newly hired science teachers' practices are developing in a complex policy environment. However, little is known about how newly hired science teachers' practices are enacted throughout a cycle of instruction and how these practices can be influenced by macro-, meso-, and micro-policies. Knowing how policies impact practice can result in better policies or better support for certain policies in order to enhance the instruction of newly hired teachers. This comparative study investigated how 12 newly hired science teachers at sites in South Africa (SA) and the United States (US) progressed through an instructional cycle of planning, teaching, and reflection. The qualitative data were analysed through beginning teacher competency frameworks, the cycle of instruction, and institutional theory. Data analysis revealed prevailing areas of practice and connections to levels of policy within the instructional cycle phases. There were some differences between the SA and US teachers and among first-, second-, and third-year teachers. More importantly, this study indicates that newly hired teachers are susceptible to micro-policies and are progressively developing their practice. It also shows the importance of meso-level connectors. It suggests that teacher educators and policy makers must consider how to prepare and support newly hired science teachers to achieve the shared global visions of science teaching.

The institutional logic of integrated care: an ethnography of patient transitions.

Shaw, James A; Kontos, Pia; Martin, Wendy; Victor, Christina

2017-03-20

Purpose The purpose of this paper is to use theories of institutional logics and institutional entrepreneurship to examine how and why macro-, meso-, and micro-level influences inter-relate in the implementation of integrated transitional care out of hospital in the English National Health Service. Design/methodology/approach The authors conducted an ethnographic case study of a hospital and surrounding services within a large urban centre in England. Specific methods included qualitative interviews with patients/caregivers, health/social care providers, and organizational leaders; observations of hospital transition planning meetings, community "hub" meetings, and other instances of transition planning; reviews of patient records; and analysis of key policy documents. Analysis was iterative and informed by theory on institutional logics and institutional entrepreneurship. Findings Organizational leaders at the meso-level of health and social care promoted a partnership logic of integrated care in response to conflicting institutional ideas found within a key macro-level policy enacted in 2003 (The Community Care (Delayed Discharges) Act). Through institutional entrepreneurship at the micro-level, the partnership logic became manifest in the form of relationship work among health and social care providers; they sought to build strong interpersonal relationships to enact more integrated transitional care. Originality/value This study has three key implications. First, efforts to promote integrated care should strategically include institutional entrepreneurs at the organizational and clinical levels. Second, integrated care initiatives should emphasize relationship-building among health and social care providers. Finally, theoretical development on institutional logics should further examine the role of interpersonal relationships in facilitating the "spread" of logics between macro-, meso-, and micro-level influences on inter-organizational change.

Development of the Macro Command Editing Executive System for Factory Workers-Oriented Programless Visual Inspection System

Anezaki, Takashi; Wakitani, Kouichi; Nakamura, Masatoshi; Kubo, Hiroyasu

Because visual inspection systems are difficult to tune, they create many problems for the kaizen process. This results in increased development costs and time to assure that the inspection systems function properly. In order to improve inspection system development, we designed an easy-tuning system called a “Program-less” visual inspection system. The ROI macro command which consisted of eight kinds of shape recognition macro commands and decision, operation, control commands was built. Furthermore, the macro command editing executive system was developed by the operation of only the GUI without editing source program. The validity of the ROI macro command was proved by the application of 488 places.

Development of a report card on healthy food environments and nutrition for children in Canada.

2014-12-01

The purpose of the Report Card on Healthy Food Environments and Nutrition for Children is to assess how current environments and policies in Canada support or create barriers to improving children's dietary behaviours and body weights. In 2014 we reviewed the literature to identify indicators of the quality of children's food environments and related policies. Scoring systems used to monitor and report on progress on a variety of public health activities were consulted during development of a grading scheme. The Report Card was revised following reviews by an Expert Advisory Committee. The Report Card assigns a grade to policies and actions (42 indicators and benchmarks) within 4 micro-environments (physical, communication, economic, social) and within the political macro-environment. Grade-level scores of A through F are assigned that reflect achievement of, supports for, and monitoring of indicator-specific benchmarks. A Canadian Report Card will be released annually starting in 2015. The Report Card is a novel tool to monitor the state of children's food environments and supportive policies, inform stakeholders of the state of these environments and policies, engage society in a national discussion, and outline a policy-relevant research agenda for further study.

2011-01-01

The authors investigate three hypotheses on the influence of labor market deregulation, decommodification, and investment in active labor market policies on the employment of chronically ill and disabled people. The study explores the interaction between employment, chronic illness, and educational level for men and women in Canada, Denmark, Norway, Sweden, and the United Kingdom, countries with advanced social welfare systems and universal health care but with varying types of active and passive labor market policies. People with chronic illness were found to fare better in employment terms in the Nordic countries than in Canada or the United Kingdom. Their employment chances also varied by educational level and country. The employment impact of having both chronic illness and low education was not just additive but synergistic. This amplification was strongest for British men and women, Norwegian men, and Danish women. Hypotheses on the disincentive effects of tighter employment regulation or more generous welfare benefits were not supported. The hypothesis that greater investments in active labor market policies may improve the employment of chronically ill people was partially supported. Attention must be paid to the differential impact of macro-level policies on the labor market participation of chronically ill and disabled people with low education, a group facing multiple barriers to gaining employment.

The financial crisis and global health: the International Monetary Fund's (IMF) policy response.

Ruckert, Arne; Labonté, Ronald

2013-09-01

In this article, we interrogate the policy response of the International Monetary Fund (IMF) to the global financial crisis, and discuss the likely global health implications, especially in low-income countries. In doing so, we ask if the IMF has meaningfully loosened its fiscal deficit targets in light of the economic challenges posed by the financial crisis and adjusted its macro-economic policy advice to this new reality; or has the rhetoric of counter-cyclical spending failed to translate into additional fiscal space for IMF loan-recipient countries, with negative health consequences? To answer these questions, we assess several post-crisis IMF lending agreements with countries requiring financial assistance, and draw upon recent academic studies and civil society reports examining policy conditionalities still being prescribed by the IMF. We also reference recent studies examining the health impacts of these conditionalities. We demonstrate that while the IMF has been somewhat more flexible in its crisis response than in previous episodes of financial upheaval, there has been no meaningful rethinking in the application of dominant neoliberal macro-economic policies. After showing some flexibility in the initial crisis response, the IMF is pushing for excessive contraction in most low and middle-income countries. We conclude that there remains a wide gap between the rhetoric and the reality of the IMF's policy and programming advice, with negative implications for global health.

Ricci, Donald R.; de Vries, Joost; Blanc, Raphael

2017-01-01

ABSTRACT Establishing a national health policy at a macro level involves the integration of a series of health initiatives across a spectrum of activities, including clinical care. Evaluation of the safety and efficacy of a new medical device ultimately evolves to testing in humans. The pathway to a formal prospective clinical trial includes a stepwise appreciation of pre-clinical data and detailed analysis of data obtained from preliminary registries, where information about appropriate patient selection and use of the device is obtained. Evaluation of procedural and follow-up efficacy and safety data in a preliminary series of cases, chosen to simulate published data, allows the design and conduct of clinical trials that are required to verify preliminary observations, closing the loop on one aspect of modifying health policy decisions.

An ethnographic exploration of influences on prescribing in general practice: why is there variation in prescribing practices?

Prescribing is a core activity for general practitioners, yet significant variation in the quality of prescribing has been reported. This suggests there may be room for improvement in the application of the current best research evidence. There has been substantial investment in technologies and interventions to address this issue, but effect sizes so far have been small to moderate. This suggests that prescribing is a decision-making process that is not sufficiently understood. By understanding more about prescribing processes and the implementation of research evidence, variation may more easily be understood and more effective interventions proposed. An ethnographic study in three Scottish general practices with diverse organizational characteristics. Practices were ranked by their performance against Audit Scotland prescribing quality indicators, incorporating established best research evidence. Two practices of high prescribing quality and one practice of low prescribing quality were recruited. Participant observation, formal and informal interviews, and a review of practice documentation were employed. Practices ranked as high prescribing quality consistently made and applied macro and micro prescribing decisions, whereas the low-ranking practice only made micro prescribing decisions. Macro prescribing decisions were collective, policy decisions made considering research evidence in light of the average patient, one disease, condition, or drug. Micro prescribing decisions were made in consultation with the patient considering their views, preferences, circumstances and other conditions (if necessary).Although micro prescribing can operate independently, the implementation of evidence-based, quality prescribing was attributable to an interdependent relationship. Macro prescribing policy enabled prescribing decisions to be based on scientific evidence and applied consistently where possible. Ultimately, this influenced prescribing decisions that occur at the micro level in consultation with patients. General practitioners in the higher prescribing quality practices made two different 'types' of prescribing decision; macro and micro. Macro prescribing informs micro prescribing and without a macro basis to draw upon the low-ranked practice had no effective mechanism to engage with, reflect on and implement relevant evidence. Practices that recognize these two levels of decision making about prescribing are more likely to be able to implement higher quality evidence.

The ubuntu paradigm in curriculum work, language of instruction and assessment

Brock-Utne, Birgit

2016-02-01

This article discusses the concept " ubuntu", an African worldview rooted in the communal character of African life. Some of the same thinking can, however, be found in various Eurasian and Latin-American philosophies. The concept " ubuntu" is also used in language planning: here, the question of language of instruction is discussed through an ubuntu paradigm. The article focuses on policies regarding language in education, both at the micro-level, where translanguaging and code-switching are central, and at the macro-level, where Prestige Planning is discussed. The assessment practices taking place in schools are also looked at through an ubuntu lens. How far is it possible for developing countries to adhere to an education policy based on their own values when they have to participate in tests like Trends in International Mathematics and Science Study (TIMSS) and the Programme for International Student Assessment (PISA) for Development?

2016-05-31

Richard Saltman and Antonio Duran take up the challenging issue of governance in their article "Governance, Government and the Search for New Provider Models," and use two case studies of health policy changes in Sweden and Spain to shed light on the subject. In this commentary, I seek to link their conceptualization of governance, especially its interrelated roles at the macro, meso, and micro levels of health systems, with the case studies on which they report. While the case studies focus on the shifts in governance between the macro and meso levels and their impacts on achievement of desired policy outcomes, they also highlight the need to better integrate the dynamics of day to day operations within micro organizations into the overall governance picture. © 2016 by Kerman University of Medical Sciences.

Modeling the Impact of Alternative Immunization Strategies: Using Matrices as Memory Lanes

PubMed Central

Alonso, Wladimir J.; Rabaa, Maia A.; Giglio, Ricardo; Miller, Mark A.; Schuck-Paim, Cynthia

Existing modeling approaches are divided between a focus on the constitutive (micro) elements of systems or on higher (macro) organization levels. Micro-level models enable consideration of individual histories and interactions, but can be unstable and subject to cumulative errors. Macro-level models focus on average population properties, but may hide relevant heterogeneity at the micro-scale. We present a framework that integrates both approaches through the use of temporally structured matrices that can take large numbers of variables into account. Matrices are composed of several bidimensional (time×age) grids, each representing a state (e.g. physiological, immunological, socio-demographic). Time and age are primary indices linking grids. These matrices preserve the entire history of all population strata and enable the use of historical events, parameters and states dynamically in the modeling process. This framework is applicable across fields, but particularly suitable to simulate the impact of alternative immunization policies. We demonstrate the framework by examining alternative strategies to accelerate measles elimination in 15 developing countries. The model recaptured long-endorsed policies in measles control, showing that where a single routine measles-containing vaccine is employed with low coverage, any improvement in coverage is more effective than a second dose. It also identified an opportunity to save thousands of lives in India at attractively low costs through the implementation of supplementary immunization campaigns. The flexibility of the approach presented enables estimating the effectiveness of different immunization policies in highly complex contexts involving multiple and historical influences from different hierarchical levels.

The techno-economic characteristics of macro-algae utilisation from European temperate zones was evaluated in a selected Anaerobic Digester (AD) using the chemical process modelling software ECLIPSE. The assessment covered the mass and energy balance of the entire process followed by the economic feasibility study, which included the total cost estimation, net present value calculation, and sensitivity analysis. The selected plant size corresponded to a community based AD of 1.6 MWth with a macro-algae feed rate of 8.64 tonnes per day (dry basis). The produced biogas was utilised in a combined heat and power plant generating 237 kWenet electricity and 367 kWth heat. The breakeven electricity-selling price in this study was estimated at around €120/MWh. On the ground of different national and regional policies, this study did not account for any government incentives. However, different support mechanisms such as Feed-in-Tariffs or Renewable Obligation Certificates can significantly improve the project viability. Copyright © 2013 Elsevier Ltd.

We use a variety of different datasets from Thailand to study not only the extremes of micro and macro variables but also within-country flow of funds and labor migration. We develop a general equilibrium model that encompasses regional variation in the type of financial friction and calibrate it to measured variation in regional aggregates. The model predicts substantial capital and labor flows from rural to urban areas even though these differ only in the underlying financial regime. Predictions for micro variables not used directly provide a model validation. Finally, we estimate the impact of a policy of counterfactual, regional isolationism.

Hermansyah, Andi; Sainsbury, Erica; Krass, Ines

The nature of Australian community pharmacy is continually evolving, raising the need to explore the current situation in order to understand the potential impact of any changes. Although community pharmacy has the potential to play a greater role in health care, it is currently not meeting this potential. To investigate the nature of the contemporary practice of community pharmacy in Australia and examine the potential missed opportunities for role expansion in health care. In-depth semi-structured interviews with a wide-range of key stakeholders within and beyond community pharmacy circles were conducted. Interviews were audio-recorded, transcribed verbatim and analyzed for emerging themes. Twenty-seven key informants across Eastern half of Australia were interviewed between December 2014 and August 2015. Several key elements of the current situation representing the social, economic and policy context of community pharmacy have been identified. These elements operate interdependently, influence micro, meso and macro levels of community pharmacy operation and are changing in the current climate. Community pharmacy has untapped potential in primary health care, but it has been slow to change to meet opportunities available in the current situation. As the current situation is complex, interrelated and dynamic with often unintended and unpredictable consequences, this paper suggests that policy makers to consider the micro, meso and macro levels of community pharmacy operation when making significant policy changes. The framework proposed in this study can be a helpful tool to analyze the processes operating at these three levels and their influences on practice. Copyright © 2016 Elsevier Inc.

2017-04-01

New approaches to universal eating disorders prevention and interventions targeting macro-environmental change are greatly needed, and research-to-policy translation efforts hold promise for advancing both of these goals. This paper describes as a policy-translation case example an academic-community-government partnership of the Strategic Training Initiative for the Prevention of Eating Disorders, Multi-Service Eating Disorders Association, and the office of Massachusetts Representative Kay Khan, all based in Massachusetts, USA. The partnership's research-to-policy translation project focused on dietary supplements sold for weight loss and muscle building, which have been linked with serious injury and death in consumers. Youth and people of all ages with eating disorders and body dysmorphic disorder may be especially vulnerable to use these products due to deceptive promises of fast and safe weight loss and muscle gain. The research-to-policy translation project was informed by a triggers-to-action framework to establish the evidentiary base of harm to consumers, operationalize policy solutions to mitigate harm through legislation, and generate political will to support action through legislation introduced in the Massachusetts legislature to restrict sales of weight-loss and muscle-building dietary supplements. The paper concludes with lessons learned from this unique policy translation effort for the prevention of disordered weight and shape control behaviors and offers recommendations for next steps for the field to advance research and practice for universal, macro-environmentally targeted prevention.

2017-03-01

In order to promote the large-scale development of the green building in our country, DEMATEL method was used to classify influence factors of green building development into three parts, including green building market, green technology and macro economy. Through the DEMATEL model, the interaction mechanism of each part was analyzed. The mutual influence degree of each barrier factor that affects the green building promotion was quantitatively analysed and key factors for the development of green building in China were also finally determined. In addition, some implementation strategies of promoting green building scale development in our country were put forward. This research will show important reference value and practical value for making policies of the green building promotion.

Background Over the past years concerns are rising about the use of Evidence-Based Medicine (EBM) in health care. The calls for an increase in the practice of EBM, seem to be obstructed by many barriers preventing the implementation of evidence-based thinking and acting in general practice. This study aims to explore the barriers of Flemish GPs (General Practitioners) to the implementation of EBM in routine clinical work and to identify possible strategies for integrating EBM in daily work. Methods We used a qualitative research strategy to gather and analyse data. We organised focus groups between September 2002 and April 2003. The focus group data were analysed using a combined strategy of 'between-case' analysis and 'grounded theory approach'. Thirty-one general practitioners participated in four focus groups. Purposeful sampling was used to recruit participants. Results A basic classification model documents the influencing factors and actors on a micro-, meso- as well as macro-level. Patients, colleagues, competences, logistics and time were identified on the micro-level (the GPs' individual practice), commercial and consumer organisations on the meso-level (institutions, organisations) and health care policy, media and specific characteristics of evidence on the macro-level (policy level and international scientific community). Existing barriers and possible strategies to overcome these barriers were described. Conclusion In order to implement EBM in routine general practice, an integrated approach on different levels needs to be developed. PMID:16153300

Services for people with communication disability in Fiji: barriers and drivers of change.

PubMed

Hopf, Suzanne C; McLeod, Sharynne

2015-01-01

The World Health Organization's World report on disability calls upon all nations to 'remove the barriers which prevent [people with disabilities] from participating in their communities; getting a quality education, finding decent work, and having their voices heard' (p. 5). People with communication disability (PWCD), as a consequence of their atypical communication, may be more likely to be excluded from society, and denied their basic human rights, than other people with disability. Fiji, a multicultural and multilingual nation in the south-western Pacific Ocean, has limited services for PWCD. Service providers in Fiji include disability care workers, special education teachers, traditional healers, and a small number of visiting volunteer speech-language pathologists. This paper outlines the historical and current barriers to, and drivers of change for, service development for PWCD in Fiji. Five barriers to service development for PWCD in Fiji were identified. (1) A major structural barrier is the small population size to develop appropriate infrastructure including professional education programs. (2) Geographical barriers include the dispersed geography across 300 islands, low population density, the rural-urban divide, and risk of disaster from cyclones and flooding. (3) Linguistic diversity, while culturally important, can present a barrier to the provision of quality services that are available in the languages spoken by PWCD. (4) Cultural barriers include historical political instability, although Fiji has become more stable due to the recent democratic elections. The social climate affects development of services that are appropriate for different dominant cultural groups. (5) Financial barriers include low gross domestic product, low financial security and low human development index; however, the financial outlook for Fiji is steadily improving due to the change in political stability. Three levels of drivers of change were identified. Macro-level drivers included Fiji's endorsement of international policy and increased globalisation (eg tourism). Meso-level drivers of change included receipt of foreign aid and support from international non-government organisations, development of disability-inclusive legislation and policy within Fiji, and strengthening of government policies that support disabled people's organisations. Micro-level drivers of change included establishment of disabled people's organisations by consumers, adoption of disability-inclusive policy and procedures by service providers, and changes in the perceptions of disability within the general community. Fijian prevalence data confirms that there is an underserved population of PWCD in need of specialist services. Significant advocacy work in the disability field by Fijian and international disabled people's organisations has led to the Fiji government signing international policy (eg Convention on the Rights of Peoples with Disabilities), inclusion of disability rights in national legislation (eg 2013 Constitution of Fiji Islands) and localised policy and practice documentation (eg inclusive education policy by the Fiji Islands Ministry of Education). Continued service development is required if Fijians with communication disability are to have their needs met. The drivers of change at all levels are positioned well to overcome current barriers to change; however, a coordinated approach including macro-, meso-, and micro-level drivers is required to ensure the future development of adequate services for PWCD in Fiji.

Proximal and distal determinants of stressful work: framework and analysis of retrospective European data.

Wahrendorf, Morten; Siegrist, Johannes

2014-08-15

While robust evidence on associations of stressful work with health exists, less research is available on determinants of stressful work in terms of respondents' characteristics (proximal factors) and in terms of national labour market policies (distal factors). In this article we analyse proximal (childhood circumstances and labour market disadvantage) and distal determinants (national compensation and integration policies) of stressful work in a comprehensive framework. We use data from the third wave of the Survey of Health, Ageing and Retirement in Europe (SHARE), with retrospective information on individual life courses collected among 11181 retired men and women in 13 European countries (2008-2009). To test our hypotheses we estimate multilevel regression models. Results show that stressful work is related to disadvantaged circumstances during childhood. To some extent this association is explained by labour market disadvantage during adulthood. Additionally, well developed labour market integration policies are related to lower overall levels of stressful work at national level. This analysis provides first evidence of important determinants of stressful work, both in terms of pre-employment conditions (childhood circumstances) and in terms of contextual macro-social policies.

Overweight and obesity in India: policy issues from an exploratory multi-level analysis.

Siddiqui, Md Zakaria; Donato, Ronald

2016-06-01

This article analyses a nationally representative household dataset-the National Family Health Survey (NFHS-3) conducted in 2005 to 2006-to examine factors influencing the prevalence of overweight/obesity in India. The dataset was disaggregated into four sub-population groups-urban and rural females and males-and multi-level logit regression models were used to estimate the impact of particular covariates on the likelihood of overweight/obesity. The multi-level modelling approach aimed to identify individual and macro-level contextual factors influencing this health outcome. In contrast to most studies on low-income developing countries, the findings reveal that education for females beyond a particular level of educational attainment exhibits a negative relationship with the likelihood of overweight/obesity. This relationship was not observed for males. Muslim females and all Sikh sub-populations have a higher likelihood of overweight/obesity suggesting the importance of socio-cultural influences. The results also show that the relationship between wealth and the probability of overweight/obesity is stronger for males than females highlighting the differential impact of increasing socio-economic status on gender. Multi-level analysis reveals that states exerted an independent influence on the likelihood of overweight/obesity beyond individual-level covariates, reflecting the importance of spatially related contextual factors on overweight/obesity. While this study does not disentangle macro-level 'obesogenic' environmental factors from socio-cultural network influences, the results highlight the need to refrain from adopting a 'one size fits all' policy approach in addressing the overweight/obesity epidemic facing India. Instead, policy implementation requires a more nuanced and targeted approach to incorporate the growing recognition of socio-cultural and spatial contextual factors impacting on healthy behaviours. © The Author 2015.

The ethical aspects of the distribution of resources for health care at the macro level deserve more study than they hitherto received. The socio-medical and economic policy implications of four distribution principles are reviewed: the utilitarian, the egalitarian, the equal access and the libertarian. Policy in welfare states is primarily based on the equal access principle. Economic factors have led to policy proposals in libertarian and utilitarian directions; competition, cost-sharing, cost-effectiveness and individual responsibility are central to the discussion. The authors conclude that it remains to be seen whether these alternatives produce the results expected. They recommend more comprehensive examination of the practical and political feasibilities of a more egalitarian policy.

How do macro-level contexts and policies affect the employment chances of chronically ill and disabled people? Part I: The impact of recession and deindustrialization.

Low employment rates of chronically ill and disabled people are of serious concern. Being out of work increases the risk of poverty and social exclusion, which may further damage the health of these groups, exacerbating health inequalities. Macro-level policies have a potentially tremendous impact on their employment chances, and these influences urgently need to be understood as the current economic crisis intensifies. In Part I of this two-part study, the authors examine employment trends for people who report a chronic illness or disability, by gender and educational level, in Canada, Denmark, Norway, Sweden, and the United Kingdom in the context of economic booms and busts and deindustrialization. People with the double burden of chronic illness and low education have become increasingly marginalized from the labor market. Deindustrialization may have played a part in this process. In addition, periods of high unemployment have sparked a downward trend in employment for already marginalized groups who did not feel the benefits when the economy improved. Norway and Sweden have been better able to protect the employment of these groups than the United Kingdom and Canada. These contextual differences suggest that other macro-level factors, such as active and passive labor market polices, may be important, as examined in part II.

Towards developing a backing layer for proton exchange membrane electrolyzers

Current energy policies require the urgent replacement of fossil energy carriers by carbon neutral ones, such as hydrogen. The backing or micro-porous layer plays an important role in the performance of hydrogen proton exchange membrane (PEM) fuel cells, reducing contact resistance and improving reactant/product management. Such carbon-based coating cannot be used in PEM electrolysis since it oxidizes to CO2 at high voltages. A functional titanium macro-porous layer (MPL) on the current collectors of a PEM electrolyzer is developed by thermal spraying. It improves the contact with the catalyst layers by ca. 20 mΩ cm2, increasing significantly the efficiency of the device when operating at high current densities.

Policy and organizational implications of gender imbalance in the NHS.

PubMed

Miller, Karen

2007-01-01

The purpose of the paper is to examine the policy and organizational implications of gender imbalance in management, which research suggests exists in the NHS. The research in this paper involved a qualitative approach with an analysis of elite interviews conducted with a non-random sample of officials involved in health policy and interviews with a random sample of senior managers in NHS Scotland. The research formed part of a larger study, which explored the enablers and inhibitors to female career progression in various Scottish sectors. The paper finds that gender imbalance in management exists in the NHS. This is manifested in a masculine organizational context, leadership and policy decision-making process, which have implications for female career advancement opportunities and subsequently access to macro policy decisions. The paper involved a sample (30 percent) of senior managers and examined policy processes in NHS Scotland. To improve the external validity of the findings further research should be conducted in NHS organizations in England and Wales. The findings in the paper suggest that gender imbalance in management and a masculine organizational context and leadership style within the NHS create a less than conducive environment for female employees. This has practical implications in terms of levels of part-time employment, career progression and attrition rates. The paper adds to the debate of gender and organizational studies by examining the health sector, which has high levels of female employment but low levels of female representation at senior management levels. The paper therefore adds to an often-neglected area of study, women in leadership and senior managerial positions. The paper is original in its approach by examining the micro and meso organizational dimensions which impact on women's ability to influence macro health policy.

Policy initiatives, culture and the prevention and control of chronic non-communicable diseases (NCDs) in the Caribbean.

To explore interactions between disease burden, culture and the policy response to non-communicable diseases (NCDs) within the Caribbean, a region with some of the highest prevalence rates, morbidity and mortality from NCDs in the Americas. We undertook a wide ranging narrative review, drawing on a variety of peer reviewed, government and intergovernmental literature. Although the Caribbean is highly diverse, linguistically and ethnically, it is possible to show how 'culture' at the macro-level has been shaped by shared historic, economic and political experiences and ties. We suggest four broad groupings of countries: the English-speaking Caribbean Community (CARICOM); the small island states that are still colonies or departments of colonial powers; three large-Spanish speaking countries; and Haiti, which although part of CARICOM is culturally distinct. We explore how NCD health policies in the region stem from and are influenced by the broad characteristics of these groupings, albeit played out in varied ways in individual countries. For example, the Port of Spain declaration (2007) on NCDs can be understood as the product of the co-operative and collaborative relationships with CARICOM, which are based on a shared broad culture. We note, however, that studies investigating the relationships between the formation of NCD policy and culture (at any level) are scarce. Within the Caribbean region it is possible to discern relationships between culture at the macro-level and the formation of NCD policy. However, there is little work that directly assesses the interactions between culture and NCD policy formation. The Caribbean with its cultural diversity and high burden of NCDs provides an ideal environment within which to undertake further studies to better understand the interactions between culture and health policy formation.

People who inject drugs (PWID) are underserved by health providers but pharmacies may be their most accessible care settings. Studies in the U.S., Russia, Vietnam, China, Canada and Mexico employed a three-level (macro-, meso-, and micro-) model to assess feasibility of expanded pharmacy services for PWID. Studies employed qualitative and quantitative interviews, review of legal and policy documents, and information on the knowledge, attitudes, and practices of key stakeholders. Studies produced a mixed assessment of feasibility. Provision of information and referrals by pharmacies is permissible in all study sites and sale and safe disposal of needles/syringes by pharmacies is legal in almost all sites, although needle/syringe sales face challenges related to attitudes and practices of pharmacists, police, and other actors. Pharmacy provision of HIV testing, hepatitis vaccination, opioid substitution treatment, provision of naloxone for drug overdose, and abscess treatment, face more serious legal and policy barriers. Challenges to expanded services for drug users in pharmacies exist at all three levels, especially the macro-level characterized by legal barriers and persistent stigmatization of PWID. Where deficiencies in laws, policies, and community attitudes block implementation, stakeholders should advocate for needed legal and policy changes and work to address community stigma and resistance. Laws and policies are only as good as their implementation, so attention is also needed to meso- and micro- levels. Policies, attitudes, and practices of police departments and pharmacy chains as well as knowledge, attitudes, and practices of individual PWID, individual pharmacies, and police officers should support rather than undermine positive laws and expanded services. Despite the challenges, pharmacies remain potentially important venues for delivering health services to PWID.

How do organizations and social policies 'acculturate' to immigrants? Accommodating skilled immigrants in Canada.

PubMed

Sakamoto, Izumi; Wei, Yi; Truong, Lele

2008-12-01

While the idea of acculturation (Berry 1997) was originally proposed as the mutual change of both parties (e.g., immigrants and the host society), the change processes of host societies are neglected in research. A grounded theory study explored the efforts of human service organizations to 'acculturate' to an increasingly diverse immigrant population, through interviews conducted with service providers serving Mainland Chinese immigrants. Acculturation efforts of human service organizations (mezzo-level acculturation) were often needs-driven and affected by the political will and resultant funding programs (macro-level forces). Even with limitations, human service organizations commonly focused on hiring Mainland Chinese immigrants to reflect the changing demographics of their clientele and creating new programs to meet the language and cultural backgrounds of the clients. To contextualize these organizational efforts, an analysis of how policy changes (macro-level acculturation) interact with organizational practice is presented. Finally, the meaning of acculturation for the host society is discussed.

Conceptualization of quality of care - in terms of what individuals, groups and organizations include in their meaning of quality, is an unexplored research area. It is important to understand how quality is conceptualised as a means to successfully implement improvement efforts and bridge potential disconnect in language about quality between system levels, professions, and clinical services. The aim is therefore to explore and compare conceptualization of quality among national bodies (macro level), senior hospital managers (meso level), and professional groups within clinical micro systems (micro level) in a cross-national study. This cross-national multi-level case study combines analysis of national policy documents and regulations at the macro level with semi-structured interviews (383) and non-participant observation (803 hours) of key meetings and shadowing of staff at the meso and micro levels in ten purposively sampled European hospitals (England, the Netherlands, Portugal, Sweden, and Norway). Fieldwork at the meso and micro levels was undertaken over a 12-month period (2011-2012) and different types of micro systems were included (maternity, oncology, orthopaedics, elderly care, intensive care, and geriatrics). The three quality dimensions clinical effectiveness, patient safety, and patient experience were incorporated in macro level policies in all countries. Senior hospital managers adopted a similar conceptualization, but also included efficiency and costs in their conceptualization of quality. 'Quality' in the forms of measuring indicators and performance management were dominant among senior hospital managers (with clinical and non-clinical background). The differential emphasis on the three quality dimensions was strongly linked to professional roles, personal ideas, and beliefs at the micro level. Clinical effectiveness was dominant among physicians (evidence-based approach), while patient experience was dominant among nurses (patient-centered care, enough time to talk with patients). Conceptualization varied between micro systems depending on the type of services provided. The quality conceptualization differed across system levels (macro-meso-micro), among professional groups (nurses, doctors, managers), and between the studied micro systems in our ten sampled European hospitals. This entails a managerial alignment challenge translating macro level quality definitions into different local contexts.

To explore the contextual influences on childhood obesity in Tehran, Iran to inform future development of an obesity prevention intervention for Iranian primary school children. Qualitative study. Focus groups and interviews with parents and school staff were convened to explore their perceptions of the causes of childhood obesity. Eleven focus groups and three interviews were held with parents and school staff (88 participants in total) from three different socio-economic areas in Iran's capital city, Tehran. All the discussions were transcribed verbatim in Persian. An iterative thematic approach was used for data analysis. Overall, the causes of childhood obesity were perceived to relate to macro-level policy influences, the school environment, sociocultural factors, and family and individual behavioural factors, acting in combination. A key emergent theme was the pervasive influence of Government policies on children's food intake and physical activity. Another key theme was the political and sociocultural context that does not support girls and women in Iran in having active lifestyles. The findings suggest that parents and school staff have sophisticated views on the possible causes of childhood overweight and obesity which encompassed behavioural, structural and social causes. A prominent emerging theme was the need for state level intervention and support for a healthy environment. Any local initiatives in Iran are unlikely to be successful without such support. Childhood obesity is growing in Iran and it is seen as one of the features of the nutrition transition in developing countries. Findings from cross-sectional studies suggest a range of lifestyle factors contribute to obesity in the Iranian population. This qualitative study explores the socioenvironmental changes contributing to childhood obesity in primary school-aged children in Iran. Findings have provided important contextual data on the perceived contributors to childhood obesity in Iran, such as macro-level policy influences on accessibility to healthy food and physical activity, competing priorities at school level, sociocultural influences on diet and physical activity and limited knowledge and skills of parents. This has laid the foundation for the development of appropriate childhood obesity prevention interventions. Copyright © 2013 The Royal Society for Public Health. Published by Elsevier Ltd.

There have been great efforts to develop traffic crash prediction models for various types of facilities. The crash models have played a key role to identify crash hotspots and evaluate safety countermeasures. In recent, many macro-level crash prediction models have been developed to incorporate highway safety considerations in the long-term transportation planning process. Although the numerous macro-level studies have found that a variety of demographic and socioeconomic zonal characteristics have substantial effects on traffic safety, few studies have attempted to coalesce micro-level with macro-level data from existing geographic units for estimating crash models. In this study, the authors have developed a series of intersection crash models for total, severe, pedestrian, and bicycle crashes with macro-level data for seven spatial units. The study revealed that the total, severe, and bicycle crash models with ZIP-code tabulation area data performs the best, and the pedestrian crash models with census tract-based data outperforms the competing models. Furthermore, it was uncovered that intersection crash models can be drastically improved by only including random-effects for macro-level entities. Besides, the intersection crash models are even further enhanced by including other macro-level variables. Lastly, the pedestrian and bicycle crash modeling results imply that several macro-level variables (e.g., population density, proportions of specific age group, commuters who walk, or commuters using bicycle, etc.) can be a good surrogate exposure for those crashes.

Abstract How abortion is dealt with in law and policy is shaped through the multiple political and societal discourses on the issue within a particular society. Debate on abortion is constantly in flux, with progressive and regressive movements witnessed globally. This paper examines the translation of human rights norms into discourses on abortion in Northern Ireland, a region where abortion is highly restricted, with extensive contemporary public debate into potential liberalization of abortion law. This paper emanates from research examining political debates on abortion in Northern Ireland and contrasts findings with recent civil society developments, identifying competing narratives of human rights with regard to abortion at the macro- and micro-political level. The paper identifies the complexities of using human rights as a lobbying tool, and questions the utility of rights-based arguments in furthering abortion law reform. The paper concludes that a legalistic rights-based approach may have limited efficacy in creating a more nuanced debate and perspective on abortion in Northern Ireland but that it has particular resonance in arguing for limited reform in extreme cases.

Informing policy makers about future health spending: a comparative analysis of forecasting methods in OECD countries.

PubMed

Astolfi, Roberto; Lorenzoni, Luca; Oderkirk, Jillian

2012-09-01

Concerns about health care expenditure growth and its long-term sustainability have risen to the top of the policy agenda in many OECD countries. As continued growth in spending places pressure on government budgets, health services provision and patients' personal finances, policy makers have launched forecasting projects to support policy planning. This comparative analysis reviewed 25 models that were developed for policy analysis in OECD countries by governments, research agencies, academics and international organisations. We observed that the policy questions that need to be addressed drive the choice of forecasting model and the model's specification. By considering both the level of aggregation of the units analysed and the level of detail of health expenditure to be projected, we identified three classes of models: micro, component-based, and macro. Virtually all models account for demographic shifts in the population, while two important influences on health expenditure growth that are the least understood include technological innovation and health-seeking behaviour. The landscape for health forecasting models is dynamic and evolving. Advances in computing technology and increases in data granularity are opening up new possibilities for the generation of system of models which become an on-going decision support tool capable of adapting to new questions as they arise.

Master standard data quantity food production code. Macro elements for synthesizing production labor time.

PubMed

Matthews, M E; Waldvogel, C F; Mahaffey, M J; Zemel, P C

1978-06-01

Preparation procedures of standardized quantity formulas were analyzed for similarities and differences in production activities, and three entrée classifications were developed, based on these activities. Two formulas from each classification were selected, preparation procedures were divided into elements of production, and the MSD Quantity Food Production Code was applied. Macro elements not included in the existing Code were simulated, coded, assigned associated Time Measurement Units, and added to the MSD Quantity Food Production Code. Repeated occurrence of similar elements within production methods indicated that macro elements could be synthesized for use within one or more entrée classifications. Basic elements were grouped, simulated, and macro elements were derived. Macro elements were applied in the simulated production of 100 portions of each entrée formula. Total production time for each formula and average production time for each entrée classification were calculated. Application of macro elements indicated that this method of predetermining production time was feasible and could be adapted by quantity foodservice managers as a decision technique used to evaluate menu mix, production personnel schedules, and allocation of equipment usage. These macro elements could serve as a basis for further development and refinement of other macro elements which could be applied to a variety of menu item formulas.

Managing partnerships and impact on decision-making: the example of health technology assessment in genetics.

PubMed

Blancquaert, Ingeborg

2006-01-01

For an emerging field such as Public Health Genetics, the partnerships that will be developed with stakeholders are of strategic importance, since they may affect long-term impact on policy-making. A concrete example in the field of health technology assessment in genetics was chosen to illustrate how the context in which scientific advisory bodies operate and the nature of partnerships developed over time influence the impact on decision-making at different levels, from the micro (professional) level through the meso (institutional) level to the macro (policy) level. As pointed out in the knowledge transfer literature, impact is not only reflected by instrumental use of knowledge, but also by problem-framing and strategic use of knowledge. Solid partnerships at the micro level, with researchers and health care professionals, are essential to build credibility and trust, and they lay the groundwork for contextualized and relevant advice and potential impact at the policy level. Even though maintaining the necessary critical distance with respect to all stakeholders is easier for institutions that are at arm's length from government, achieving the right balance between an institution's independence and service relationship is a real challenge.

The essential transcriptional repressor REST (repressor element 1-silencing transcription factor) plays central roles in development and human disease by regulating a large cohort of neural genes. These have conventionally fallen into the class of known, protein-coding genes; recently, however, several noncoding microRNA genes were identified as REST targets. Given the widespread transcription of messenger RNA-like, noncoding RNAs (“macroRNAs”), some of which are functional and implicated in disease in mammalian genomes, we sought to determine whether this class of noncoding RNAs can also be regulated by REST. By applying a new, unbiased target gene annotation pipeline to computationally discovered REST binding sites, we find that 23% of mammalian REST genomic binding sites are within 10 kb of a macroRNA gene. These putative target genes were overlooked by previous studies. Focusing on a set of 18 candidate macroRNA targets from mouse, we experimentally demonstrate that two are regulated by REST in neural stem cells. Flanking protein-coding genes are, at most, weakly repressed, suggesting specific targeting of the macroRNAs by REST. Similar to the majority of known REST target genes, both of these macroRNAs are induced during nervous system development and have neurally restricted expression profiles in adult mouse. We observe a similar phenomenon in human: the DiGeorge syndrome-associated noncoding RNA, DGCR5, is repressed by REST through a proximal upstream binding site. Therefore neural macroRNAs represent an additional component of the REST regulatory network. These macroRNAs are new candidates for understanding the role of REST in neuronal development, neurodegeneration, and cancer. PMID:19050060

2008-01-01

Background While Arab countries showed an impressive decline in child mortality rates during the past few decades, gaps in mortality by gender and socioeconomic status persisted. However, large socioeconomic disparities in child health were evident in almost every country in the region. Methods Using available tabulations and reliable micro data from national household surveys, data for 18 Arab countries were available for analysis. In addition to infant and child mortality, child health was measured by nutritional status, vaccination, and Acute Respiratory Infection (ARI). Within-country disparities in child health by gender, residence (urban/rural) and maternal educational level were described. Child health was also analyzed by macro measures of development, including per capita GDP (PPP), female literacy rates, urban population and doctors per 100,000 people. Results Gender disparities in child health using the above indicators were less evident, with most showing clear female advantage. With the exception of infant and child survival, gender disparities demonstrated a female advantage, as well as a large urban advantage and an overall advantage for mothers with secondary education. Surprisingly, the countries' rankings with respect to disparities were not associated with various macro measures of development. Conclusion The tenacity of pervasive intra-country socioeconomic disparities in child health calls for attention by policy makers and health practitioners. PMID:19021903

This study examined correlates of unprotected vaginal and anal sex (UVA) with male clients among female sex workers (FSWs). Baseline data were gathered from 1089 FSWs recruited from 13 cities across Mexico enrolled in an evidence-based sexual risk reduction intervention. We used generalised estimating equations (GEE) to predict total UVA while controlling for the nested structure of the data. Total UVA with clients in the past month was examined in relation to selected sociodemographic, substance-use, and micro- and macro-environmental factors. A greater number of UVA acts was associated with three micro-level environmental factors (i.e. never getting condoms for free, unaffordability of condoms, greater number of clients per month), and three macro-level environmental factors (i.e. lower health and higher education indices, greater population size of city). These findings suggest the development of social and structural approaches to HIV prevention for FSWs in Mexico, including modification of venue-based policies that pressure FSWs to maximise client volume, changes to the work environment that promote availability and affordability of condoms, and improved population health. Moreover, our findings call for the development of context-specific HIV interventions that take into account variations in the sexual risk behaviours and HIV risk environments of FSWs throughout Mexico.

Brussig, M

2009-08-01

For many years, Germany has been regarded in international comparisons as an example of a generous early retirement culture, resulting in a low labor market participation of older employees. Recently, however, employment rates of older employees have increased remarkably. Reasons are the demographic structure of older persons in Germany, a long-term trend of increasing female labor market participation, and reforms in labor-market policies and pension policies during the last 10 years. Despite an increasing labor market participation of older employees, traditional labor market risks for older persons partly remained, but some new risks evolved as well. Therefore, social differentiation among older employees increased.Although detailed macro descriptions exist, the causes of labor market developments cannot be fully understood with cross-sectional data alone. An important stimulus is to be expected from individual longitudinal data which reflect employment histories and labor market transitions such as employment exit and retirement.

Worldwide pharmaceutical leaders have the goals to become leader on the pharmaceutical market of Azerbaijan and maximize their market share. Non-leaders pharmaceutical companies use different strategies of price formation: prime cost plus markup, or price formation on the base of current prices. It was revealed that domestic pharmaceutical market has high demand elasticity. Future market development is related to stimulation of product development, and hard penetration to the market through realization of price formation strategy. Non-state pharmaceutical organizations to achieve the purpose of survive in conditions of high competition should take in to account the factor perceptions of assortment by customers.

Scarcity discourses and their impacts on renal care policy, practices, and everyday experiences in rural British Columbia

PubMed Central

Brassolotto, Julia; Daly, Tamara

2017-01-01

Drawing from a qualitative case study in rural British Columbia, Canada, this paper examines the discourse of kidney scarcity and its impact on renal care policies and practices. Our findings suggest that at different levels of care, there are different discourses and treatment foci. We have identified three distinct scarcity discourses at work. At the macro policy level, the scarcity of transplantable kidneys is the dominant discourse. At the meso health care institution level, we witnessed a discourse regarding the scarcity of health care and human resources. At the micro community level, there was a discourse of the scarcity of health and life-sustaining resources. For each form of scarcity, particular responses are encouraged. At the macro level, renal care and transplant organizations emphasize the benefits of kidney transplantation and procuring more donors. At the meso level, participants from the regional health care system increasingly encourage home hemodialysis and patient-led care. At the micro level, community health care professionals push for rural renal patients to attend dialysis and maintain their care plans. This work contributes to critical, interdisciplinary organ transfer discourse by contextualizing kidney scarcity. It reveals the tension between these discourses and the implications of pursuing kidney donations without addressing the conditions in which individuals experience kidney failure. PMID:26854624

"Engendering" Agenda 21: gender equality and water resource management: five years after Rio.

Hannan-andersson, C

1997-01-01

Agenda 21 acknowledges women's role in natural resources management at the local level and emphasizes the need for more women in senior positions to contribute positively to the implementation of environmental policy. This article assesses Agenda 21's approach to gender equality and its achievements. A few explicit references to women and water resource management (WRM) without consideration on the gender implications of the WRM policies and strategies were noted. The macro-oriented, technology-focused and supply-oriented approach of Agenda 21 on WRM hinders the inclusion of a gender perspective. There are two levels of implications of gender-blind intervention in relation to WRM: the issue of social justice and rights, and the negative impact of the neglect of gender inequality on overall planning and success of interventions. The inclusion of a gender perspective at policy and planning levels to facilitate the resolution of inconsistencies, as well as the importance of water sources and patterns of use knowledge for adequate policy development and planning was suggested. It is important that the WRM principle application utilize a sociocultural and gender perspective at both community and household levels before decisions are made on WRM interventions.

The application of thermal energy storage with phase change materials (PCMs) for energy efficiency of buildings grew rapidly in the last few years. In this research, octadecane paraffin was served as a PCM, and a structural concrete with the function of indoor temperature control was developed by using a macro-encapsulated PCM hollow steel ball (HSB). The macro-encapsulated PCM-HSB was prepared by incorporation of octadecane into HSBs through vacuum impregnation. Test results showed that the maximum percentage of octadecane carried by HSBs was 80.3% by mass. The macro-encapsulated PCM-HSB has a latent heat storage capacity as high as 200.5 J/g. The compressive strength of concrete with macro-encapsulated PCM-HSB at 28 days ranged from 22 to 40 MPa. The indoor thermal performance test revealed that concrete with macro-encapsulated octadecane-HSB was capable of reducing the peak indoor air temperature and the fluctuation of indoor temperature. It can be very effective in transferring the heating and cooling loads away from the peak demand times. PMID:28787859

The double burden of neoliberalism? Noncommunicable disease policies and the global political economy of risk.

Glasgow, Sara; Schrecker, Ted

2016-05-01

The growing prevalence of NCDs in low- and middle-income countries (LMICs) is now recognized as one of the major global health policy issues of the early 21st century. Current official approaches reflect ambivalence about how health policy should approach the social determinants of health identified by the WHO Commission on the topic that released its report in 2008, and in particular the role of macro-scale economic and social processes. Authoritative framing of options for NCD prevention in advance of the September, 2011 UN high-level meeting on NCDs arguably relied on a selective reading of the scientific (including social scientific) evidence, and foregrounded a limited number of risk factors defined in terms of individual behavior: tobacco use, unhealthy diet, alcohol (ab)use and physical inactivity. The effect was to reproduce at a transnational level the individualization of responsibility for health that characterizes most health promotion initiatives in high-income countries, ignoring both the limited control that many people have over their exposure to these risk factors and the contribution of macro-scale processes like trade liberalization and the marketing activities of transnational corporations to the global burden of NCDs. An alternative perspective focuses on "the inequitable distribution of power, money, and resources" described by the WHO Commission, and the ways in which policies that address those inequities can avoid unintentional incorporation of neoliberal constructions of risk and responsibility.

Macro-economic assessment of flood risk in Italy under current and future climate

Carrera, Lorenzo; Koks, Elco; Mysiak, Jaroslav; Aerts, Jeroen; Standardi, Gabriele

2014-05-01

This paper explores an integrated methodology for assessing direct and indirect costs of fluvial flooding to estimate current and future fluvial flood risk in Italy. Our methodology combines a Geographic Information System spatial approach, with a general economic equilibrium approach using a downscaled modified version of a Computable General Equilibrium model at NUTS2 scale. Given the level of uncertainty in the behavior of disaster-affected economies, the simulation considers a wide range of business recovery periods. We calculate expected annual losses for each NUTS2 region, and exceedence probability curves to determine probable maximum losses. Given a certain acceptable level of risk, we describe the conditions of flood protection and business recovery periods under which losses are contained within this limit. Because of the difference between direct costs, which are an overestimation of stock losses, and indirect costs, which represent the macro-economic effects, our results have different policy meanings. While the former is relevant for post-disaster recovery, the latter is more relevant for public policy issues, particularly for cost-benefit analysis and resilience assessment.

SAS macro programs for geographically weighted generalized linear modeling with spatial point data: applications to health research.

PubMed

Chen, Vivian Yi-Ju; Yang, Tse-Chuan

2012-08-01

An increasing interest in exploring spatial non-stationarity has generated several specialized analytic software programs; however, few of these programs can be integrated natively into a well-developed statistical environment such as SAS. We not only developed a set of SAS macro programs to fill this gap, but also expanded the geographically weighted generalized linear modeling (GWGLM) by integrating the strengths of SAS into the GWGLM framework. Three features distinguish our work. First, the macro programs of this study provide more kernel weighting functions than the existing programs. Second, with our codes the users are able to better specify the bandwidth selection process compared to the capabilities of existing programs. Third, the development of the macro programs is fully embedded in the SAS environment, providing great potential for future exploration of complicated spatially varying coefficient models in other disciplines. We provided three empirical examples to illustrate the use of the SAS macro programs and demonstrated the advantages explained above. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Analysis of the interrelationship of energy, economy, and environment: A model of a sustainable energy future for Korea

NASA Astrophysics Data System (ADS)

Boo, Kyung-Jin

The primary purpose of this dissertation is to provide the groundwork for a sustainable energy future in Korea. For this purpose, a conceptual framework of sustainable energy development was developed to provide a deeper understanding of interrelationships between energy, the economy, and the environment (E 3). Based on this theoretical work, an empirical simulation model was developed to investigate the ways in which E3 interact. This dissertation attempts to develop a unified concept of sustainable energy development by surveying multiple efforts to integrate various definitions of sustainability. Sustainable energy development should be built on the basis of three principles: ecological carrying capacity, economic efficiency, and socio-political equity. Ecological carrying capacity delineates the earth's resource constraints as well as its ability to assimilate wastes. Socio-political equity implies an equitable distribution of the benefits and costs of energy consumption and an equitable distribution of environmental burdens. Economic efficiency dictates efficient allocation of scarce resources. The simulation model is composed of three modules: an energy module, an environmental module and an economic module. Because the model is grounded on economic structural behaviorism, the dynamic nature of the current economy is effectively depicted and simulated through manipulating exogenous policy variables. This macro-economic model is used to simulate six major policy intervention scenarios. Major findings from these policy simulations were: (1) carbon taxes are the most effective means of reducing air-pollutant emissions; (2) sustainable energy development can be achieved through reinvestment of carbon taxes into energy efficiency and renewable energy programs; and (3) carbon taxes would increase a nation's welfare if reinvested in relevant areas. The policy simulation model, because it is based on neoclassical economics, has limitations such that it cannot fully account for socio-political realities (inter- and intra-generational equity) which are core feature of sustainability. Thus, alternative approaches based on qualitative analysis, such as the multi-criteria approach, will be required to complement the current policy simulation model.

The main objective of this study was to analyse the ANIS of Livestock industry in West Sumatera according to its main determinants. This research aims to know and understand the maturity level of the regional innovationsystem of West Sumatra livestock industries, including recommendation for improvements. The maturity level of the regional innovation system was analyzed with the ANIS method by using an opinion survey to some experts from businessmen, government and universities. This expert opinion survey was conducted to measure expert perceptions on the implementations of determinants of west Sumatera regional innovations systems on livestock industries on macro level (innovations policy), mezzo level (innovation institutions and programs) and micro level (innovation capacity). By using Likert method, the result showed maturity level for the West Sumatra livestock industries innovation system was still develop. This is caused by low maturity in the macro and meso determinants which are at the central and regional government side. This research result may be useful as recommendations for the government for improving the maturity level and may be a basic for incoming researches to identify regional innovation system determinants with low maturity to improve.

Sex, gender, and secondhand smoke policies: implications for disadvantaged women.

Greaves, Lorraine J; Hemsing, Natalie J

2009-08-01

Although implementation of secondhand smoke policies is increasing, little research has examined the unintended consequences of these policies for disadvantaged women. Macro-, meso-, and micro-level issues connected to secondhand smoke and women are considered to illustrate the range of ways in which sex, gender, and disadvantage affect women's exposure to secondhand smoke. A review of current literature, primarily published between 2000 and 2008, on sex- and gender-based issues related to secondhand smoke exposure and the effects of secondhand smoke policies for various subpopulations of women, including low-income girls and women, nonwhite minority women, and pregnant women, was conducted in 2008. These materials were critically analyzed using a sex and gender analysis, allowing for the drawing of inferences and reflections on the unintended effects of secondhand smoke policies on disadvantaged women. Smoke-free policies do not always have equal or even desired effects on low-income girls and women. Low-income women are more likely to be exposed to secondhand smoke, may have limited capacity to manage their exposure to secondhand smoke both at home and in the workplace, and may experience heightened stigmatization as a result of secondhand smoke policies. Various sex- and gender-related factors, such as gendered roles, unequal power differences between men and women, child-caring roles, and unequal earning power, affect exposure and responses to secondhand smoke, women's capacity to control exposure, and their responses to protective policies. In sum, a much more nuanced gender- and diversity-sensitive framework is needed to develop research and tobacco control policies that address these issues.

The Los Alamos National Laboratory's Weapon Systems Engineering division's Advanced Engineering Analysis group employs material constitutive models of composites for use in simulations of components and assemblies of interest. Experimental characterization, modeling and prediction of the macro-scale (i.e. continuum) behaviors of these composite materials is generally difficult because they exhibit nonlinear behaviors on the meso- (e.g. micro-) and macro-scales. Furthermore, it can be difficult to measure and model the mechanical responses of the individual constituents and constituent interactions in the composites of interest. Current efforts to model such composite materials rely on semi-empirical models in which meso-scale properties are inferredmore » from continuum level testing and modeling. The proposed approach involves removing the difficulties of interrogating and characterizing micro-scale behaviors by scaling-up the problem to work with macro-scale composites, with the intention of developing testing and modeling capabilities that will be applicable to the mesoscale. This approach assumes that the physical mechanisms governing the responses of the composites on the meso-scale are reproducible on the macro-scale. Working on the macro-scale simplifies the quantification of composite constituents and constituent interactions so that efforts can be focused on developing material models and the testing techniques needed for calibration and validation. Other benefits to working with macro-scale composites include the ability to engineer and manufacture—potentially using additive manufacturing techniques—composites that will support the application of advanced measurement techniques such as digital volume correlation and three-dimensional computed tomography imaging, which would aid in observing and quantifying complex behaviors that are exhibited in the macro-scale composites of interest. Ultimately, the goal of this new approach is to develop a meso-scale composite modeling framework, applicable to many composite materials, and the corresponding macroscale testing and test data interrogation techniques to support model calibration.« less

Health workforce development planning in the Sultanate of Oman: a case study.

PubMed

Ghosh, Basu

2009-06-11

Oman's recent experience in health workforce development may be viewed against the backdrop of the situation just three or four decades ago, when it had just a few physicians and nurses (mostly expatriate). All workforce categories in Oman have grown substantially over the last two decades. Increased self-reliance was achieved despite substantial growth in workforce stocks. Stocks of physicians and nurses grew significantly during 1985-2007. This development was the outcome of well-considered national policies and plans. This case outlines how Oman is continuing to turn around its excessive dependence on expatriate workforce through strategic workforce development planning. The Sultanate's early development initiatives focused on building a strong health care infrastructure by importing workforce. However, the policy-makers stressed national workforce development for a sustainable future. Beginning with the formulation of a strategic health workforce development plan in 1991, the stage was set for adopting workforce planning as an essential strategy for sustainable health development and workforce self-reliance. Oman continued to develop its educational infrastructure, and began to produce as much workforce as possible, in order to meet health care demands and achieve workforce self-reliance. Other policy initiatives with a beneficial impact on Oman's workforce development scenario were: regionalization of nursing institutes, active collaboration with universities and overseas specialty boards, qualitative improvement of the education system, development of a strong continuing professional development system, efforts to improve workforce management, planned change management and needs-based micro/macro-level studies. Strong political will and bold policy initiatives, dedicated workforce planning and educational endeavours have all contributed to help Oman to develop its health workforce stocks and gain self-reliance. Oman has successfully innovated workforce planning within a favorable policy environment. Its intensive and extensive workforce planning efforts, with the close involvement of policy-makers, educators and workforce managers, have ensured adequacy of suitable workforce in health institutions and its increased self-reliance in the health workforce. Oman's experience in workforce planning and development presents an illustration of a country benefiting from successful application of workforce planning concepts and tools. Instead of being complacent about its achievements so far, every country needs to improve or sustain its planning efforts in this way, in order to circumvent the current workforce deficiencies and to further increase self-reliance and improve workforce efficiency and effectiveness.

Design and application of a technologically explicit hybrid energy-economy policy model with micro and macro economic dynamics

NASA Astrophysics Data System (ADS)

Bataille, Christopher G. F.

2005-11-01

Are further energy efficiency gains, or more recently greenhouse gas reductions, expensive or cheap? Analysts provide conflicting advice to policy makers based on divergent modelling perspectives, a 'top-down/bottom-up debate' in which economists use equation based models that equilibrate markets by maximizing consumer welfare, and technologists use technology simulation models that minimize the financial cost of providing energy services. This thesis summarizes a long term research project to find a middle ground between these two positions that is more useful to policy makers. Starting with the individual components of a behaviourally realistic and technologically explicit simulation model (ISTUM---Inter Sectoral Technology Use Model), or "hybrid", the individual sectors of the economy are linked using a framework of micro and macro economic feedbacks. These feedbacks are taken from the economic theory that informs the computable general equilibrium (CGE) family of models. Speaking in the languages of both economists and engineers, the resulting "physical" equilibrium model of Canada (CIMS---Canadian Integrated Modeling System), equilibrates energy and end-product markets, including imports and exports, for seven regions and 15 economic sectors, including primary industry, manufacturing, transportation, commerce, residences, governmental infrastructure and the energy supply sectors. Several different policy experiments demonstrate the value-added of the model and how its results compare to top-down and bottom-up practice. In general, the results show that technical adjustments make up about half the response to simulated energy policy, and macroeconomic demand adjustments the other half. Induced technical adjustments predominate with minor policies, while the importance of macroeconomic demand adjustment increases with the strength of the policy. Results are also shown for an experiment to derive estimates of future elasticity of substitution (ESUB) and autonomous energy efficiency indices (AEEI) from the model, parameters that could be used in long-run computable general equilibrium (CGE) analysis. The thesis concludes with a summary of the strengths and weakness of the new model as a policy tool, a work plan for its further improvement, and a discussion of the general potential for technologically explicit general equilibrium modelling.

Effecting Organizational Change at the Macro Level of Professions

NASA Astrophysics Data System (ADS)

Green, Robert Anthony

Much has been written in academic and popular publications about organizational change. Topics have ranged from case studies to anecdotal stories of how leaders can change an organization. There is little written on changing the culture and vision of a profession at the macro level. This dissertation shows that one key to effecting change within a profession is to educate those at the entrant level and thereby effect change with the profession. Over time, these new entrants to the profession will rise to senior positions and be able to effect greater change through the hiring, training, and mentoring processes inherent in the professions and the organizations for which they work. One way to effect change in these entrants is through education in college and professional schools. This study is specifically focused on effecting change in the interdisciplinary field of engineering and public policy. Public policy involves countless infrastructure issues at all levels of government. Engineers are well-versed in dealing with the technical issues of infrastructure but their voice is often lacking at the policy level. Similarly, political scientists are well-versed in policy but are often lacking in a thorough understanding of the technical aspects of the policy. Through an introductory course in engineering and public policy, undergraduate students from the seemingly disparate fields of engineering and political science were placed in a common classroom and through lectures, writings, presentations, and guided discussions their attitudes on key areas were changed. Areas studied were professional interest, legitimacy, deference, the public policy process, and education outside of a specific field. Through the process of education, changes in each of these areas was possible. Further, the movement was towards making students in each discipline more open to the input, opinions, and attitudes of others, and specifically in shifting engineers toward a more positive view of the public policy process. Being exposed to these topics and to each other's thought processes, changes in professional attitudes were made. While there is not a specific profession for which any research has been done, the military is used, in places, as an analog to the profession of engineering.

E-inclusion: Beyond individual socio-demographic characteristics.

The changing demographic structure of the population, resulting in unparalleled growth of the elderly population, means that e-inclusion of this population group is considered to be a social and political priority in the context of the Information Society. Most research studies have only considered individual variables -such as age, gender, education, income and health- in the explanatory models of e-inclusion of senior citizens, while ignoring macro variables, such as the welfare systems and public policies in each country. Simultaneously, most studies focus on small-scale samples, lack international comparisons and do not consider the combined effect of several variables that influence Internet use. This study aims to analyse possible differences between two countries that have different welfare systems and public policies, after controlling for the effects of the individual variables that have been identified in the literature as relevant for Internet use. The study focuses on a sample of 8639 individuals, aged 50 years and over, residing in Portugal and Estonia, who participated in the SHARE project (Survey of Health, Ageing and Retirement in Europe). The results of the logistic regression analysis demonstrate that welfare systems and public policies have an impact on the likelihood of Internet use, thus reinforcing the importance of developing public policies to foster e-inclusion of senior citizens.

The mineral sector and economic development in Ghana: A computable general equilibrium analysis

NASA Astrophysics Data System (ADS)

Addy, Samuel N.

A computable general equilibrium model (CGE) model is formulated for conducting mineral policy analysis in the context of national economic development for Ghana. The model, called GHANAMIN, places strong emphasis on production, trade, and investment. It can be used to examine both micro and macro economic impacts of policies associated with mineral investment, taxation, and terms of trade changes, as well as mineral sector performance impacts due to technological change or the discovery of new deposits. Its economywide structure enables the study of broader development policy with a focus on individual or multiple sectors, simultaneously. After going through a period of contraction for about two decades, mining in Ghana has rebounded significantly and is currently the main foreign exchange earner. Gold alone contributed 44.7 percent of 1994 total export earnings. GHANAMIN is used to investigate the economywide impacts of mineral tax policies, world market mineral prices changes, mining investment, and increased mineral exports. It is also used for identifying key sectors for economic development. Various simulations were undertaken with the following results: Recently implemented mineral tax policies are welfare increasing, but have an accompanying decrease in the output of other export sectors. World mineral price rises stimulate an increase in real GDP; however, this increase is less than real GDP decreases associated with price declines. Investment in the non-gold mining sector increases real GDP more than investment in gold mining, because of the former's stronger linkages to the rest of the economy. Increased mineral exports are very beneficial to the overall economy. Foreign direct investment (FDI) in mining increases welfare more so than domestic capital, which is very limited. Mining investment and the increased mineral exports since 1986 have contributed significantly to the country's economic recovery, with gold mining accounting for 95 percent of the mineral sector's contribution. The mining sector in general is identified as a leading sector for economic development.

Abstract Background In the past decade, an international consensus on the value of well-functioning systems has driven considerable health systems research. This research falls into two broad categories. The first provides conceptual frameworks that take complex healthcare systems and create simplified constructs of interactions and functions. The second focuses on granular inputs and outputs. This paper presents a novel translational mapping tool – the University of California, San Francisco mapping tool (the Tool) - which bridges the gap between these two areas of research, creating a platform for multi-country comparative analysis. Methods Using the Murray-Frenk framework, we create a macro-level representation of a country's structure, focusing on how it finances and delivers healthcare. The map visually depicts the fundamental policy questions in healthcare system design: funding sources and amount spent through each source, purchasers, populations covered, provider categories; and the relationship between these entities. Results We use the Tool to provide a macro-level comparative analysis of the structure of India's and Thailand's healthcare systems. Conclusions As part of the systems strengthening arsenal, the Tool can stimulate debate about the merits and consequences of different healthcare systems structural designs, using a common framework that fosters multi-country comparative analyses.

Spending on pharmaceuticals in Italy: macro constraints with local autonomy.

PubMed

Mapelli, Vittorio; Lucioni, Carlo

2003-01-01

Italy has a national health service (SSN) that is moving toward decentralization and empowerment of local health enterprises (LHEs)-the arms of the regions for delivering health services. Drug policy and spending decisions are both influenced by central government and local authorities. At the "macro" level, the government holds the power to decide the amount of drug expenditure, currently at 13% of total SSN expenditure; the pricing policy, price negotiation, reference price, and price cuts; criteria for reimbursement, inclusion in the positive list, and restrictive notes; and the copayments and exemptions. So far, the government concern has been predominantly on cost containment, and its approach in selecting drugs for reimbursement has been cost minimization. Italy has no centralized office for health technology assessment and this hinders the search for an efficient use of drugs. At the "micro" level, however, the LHEs are showing a great vitality in fostering a better use of drugs by general practitioners. One of the tools employed is local voluntary agreements between LHEs and general practitioners (GPs) that may be supported by economic incentives, in cash or in kind. In 2000 there were 61 agreements in place, 31% of total LHEs, which concerned the respect of drug expenditure ceilings and the local development and implementation of clinical guidelines (47% of LHEs). A traditional and widespread tool for controlling drug expenditure is providing GPs with regular reports on their drug prescriptions (59% of LHEs). Monitoring, moral suasion, and clinical guidelines are the main incentives for efficiency at local level, but focus on health outcomes is limited. The cost-containment mentality still prevails and the use of drug budget for purchasing better health is at its very early stage.

This study focuses on how English General Practitioners and practice nurses make sense of a complex intervention for the management of osteoarthritis, using the macro-meso-micro contextual approach and Normalisation Process Theory (NPT), specifically the construct of coherence. It is embedded in a cluster RCT comprising four control practices and four intervention practices. In order to study sense-making by professionals introduction and planning meetings (N = 14) between researchers and the practices were observed. Three group interviews were carried out with 10 GPs and 5 practice nurses after they had received training in the intervention. Transcripts were thematically analysed before comparison with NPT constructs. We found that: first, most GPs and all nurses distinguished the intervention from current ways of working. Second, from the introduction meeting to the completion of the training the purpose of the intervention increased in clarity. Third, GPs varied in their understanding of their remit, while the practice nurses felt that the intervention builds on their holistic care approach. Fourth, the intervention was valued by practice nurses as it strengthened their expert status. GPs saw its value as work substitution, but felt that a positive conceptualisation of OA enhanced the consultation. When introducing new interventions in healthcare settings the interaction between macro, meso and micro factors, as well as the means of engaging new clinical practices and their sense-making by clinicians needs to be considered.

The problem is education not ``special education''

NASA Astrophysics Data System (ADS)

Fellner, Gene

2015-12-01

In his article, Urban special education policy and the lived experience of stigma in a high school science classroom, Chris Hale persuasively argues that the Individuals with Disabilities Education Act and subsequent special education policies have largely failed to serve special education students who are stigmatized by their deficit classification. Though classified students may be doubly stigmatized, research suggests that students of color who live in economically stressed communities are also subject to systemic educational policies that produce stigma; special education should be understood within the larger context of educational policy in the inner city. Though we cannot immediately dismantle the macro level structures that nurture stigma, I suggest pedagogies based on facilitating phenomenological awareness enacted through individual-collectively based methodologies to challenge the stigma that classified as well as non-classified students in the inner city often carry with them.

Some methodological issues in the longitudinal analysis of demographic data.

Krishinan, P

1982-12-01

Most demographic data are macro (or aggregate) in nature. Some relevant methodological issues are presented here in a time series study using aggregate data. The micro-macro distinction is relative. Time enters into the micro and macro variables in different ways. A simple micro model of rural-urban migration is given. Method 1 is to assume homogeneity in behavior. Method 2 is a Bayesian estimation. A discusssion of the results follows. Time series models of aggregate data are given. The nature of the model--predictive or explanatory--must be decided on. Explanatory models in longitudinal studies have been developed. Ways to go to the micro level from the macro are discussed. The aggregation-disaggregation problem in demography is not similar to that in econometrics. To understand small populations, separate micro level data have to be collected and analyzed and appropriate models developed. Both types of models have their uses.

Exploring the links between macro-level contextual factors and their influence on nursing workforce composition.

Research that links macro-level socioeconomic development variables to health care human resources workforce composition is scarce at best. The purpose of this study was to explore the links between nonnursing factors and nursing workforce composition through a secondary, descriptive analysis of year 2000, publicly available national nursing human resources data from Mexico. Building on previous research, the authors conducted multiple robust regression analysis by federal typing of nursing human resources from 31 Mexican states against macro-level socioeconomic development variables. Average education in a state was significantly associated in predicting all types of formally educated nurses in Mexico. Other results suggest that macro-level indicators have a different association with each type of nurse. Context may play a greater role in determining nursing workforce composition than previously thought. Further studies may help to explain differences both within and between countries.

The reactions to macro-economic crises in Nordic health system policies: Denmark, Finland and Sweden, 1980-2013.

Denmark, Finland and Sweden have experienced two major recessions during the last 25 years. The adjustments to the earlier crisis in the late 1980s (Denmark) and early 1990s (Finland and Sweden) resembled the policies in many other European countries during the present crisis. The analysis of relationship of deep economic crises and growth period between them to the health system policies and institutions in the three countries from the 1980s to 2013 is based on a categorisation of reactions to external shocks as path conforming or path breaking. The results of the empirical long-term trends show that the reactions to deep recessions have been mainly temporary adjustments and acceleration of changes already prepared before economic crisis. The economic crisis in the three countries has not been 'good enough' to enable paradigmatic changes in the Nordic public, decentralised and equity-oriented health systems. Changes such as the slow privatisation in care funding and production and the adoption of new management practices indicate an ongoing paradigmatic change related to longer-term societal, ideological and political developments rather than directly to economic crises or growth.

Health equity impact assessment.

PubMed

Povall, Susan L; Haigh, Fiona A; Abrahams, Debbie; Scott-Samuel, Alex

2014-12-01

The World Health Organization's Commission on Social Determinants of Health has called for 'health equity impact assessments' of all economic agreements, market regulation and public policies. We carried out an international study to clarify if existing health impact assessment (HIA) methods are adequate for the task of global health equity assessments. We triangulated data from a scoping review of the international literature, in-depth interviews with health equity and HIA experts and an international stakeholder workshop. We found that equity is not addressed adequately in HIAs for a variety of reasons, including inadequate guidance, absence of definitions, poor data and evidence, perceived lack of methods and tools and practitioner unwillingness or inability to address values like fairness and social justice. Current methods can address immediate, 'downstream' factors, but not the root causes of inequity. Extending HIAs to cover macro policy and global equity issues will require new tools to address macroeconomic policies, historical roots of inequities and upstream causes like power imbalances. More sensitive, participatory methods are also required. There is, however, no need for the development of a completely new methodology. © The Author (2013). Published by Oxford University Press.

The Hashemite Kingdom of Jordan is an example of a country that suffers from high water scarcity. Additionally, due to the economic drivers in the country, such as phosphate and potash extraction and pharmaceutical production, the little fresh water that remains is generally polluted. The infrastructure, often antiquated in urban areas and non-existent in rural areas, also contributes to poor water conditions and to the spread of waterborne diseases. This paper examines the socioeconomic factors that contribute to diarrhea and hepatitis A on a macro level in Jordan and discusses the public-policies that government officials could use to abate those problems. Ordinary least squares time series models are used to understand the macro-level variables that impact the incidence of these diseases in Jordan. Public health expenditure has a significant impact on reducing their incidence. Furthermore, investment in sanitation facilities in rural regions is likely to reduce the number of cases of hepatitis A. Perhaps the most surprising outcome is that importation of goods and services likely results in a decrease in cases of hepatitis A. However, income has little impact on the incidence of diarrhea and hepatitis A.

Exploring regional differences in the reading competencies of Italian students.

PubMed

Matteucci, Mariagiulia; Mignani, Stefania

2014-06-01

Recently, the study of territorial differences in educational outcomes has assumed a particular importance for the policy strategies related to the socioeconomic conditions of different geographical areas. In Italy, international surveys for student assessments have introduced a regional stratification only recently, and regular national student assessments started only in 2008. In this article, the reading performances of Italian students based on OECD-PISA 2009 are investigated, taking into account regional and macro-area partition. Student outcomes are explored by using a multilevel analysis, where school membership, socioeconomic and cultural background of students, and regional gross domestic product are introduced. The results show that, despite the existence of a unified educational system in Italy, regional and macro-area differences in student reading achievements are consolidated and variability in performances among schools is especially noticeable. Comparisons based on national assessments by INVALSI at the end of compulsory school confirm these findings. Italian policy makers are advised to take into account these results to improve learning opportunities and to reduce educational gaps. In particular, targeted regional policies are needed to improve the mean performance especially in the Southern regions of Calabria, Campania, and Sicilia, and to strengthen the system equity in several regions, such as Emilia-Romagna. To decrease the school differences, possible suggestions are to postpone the choice of the school type (currently, at age 14) and to motivate good teachers to work in schools located in the worst socioeconomic and cultural environments. © The Author(s) 2014.

Improvement of aquaponic performance through micro- and macro-nutrient addition.

Aquaponics is one of the "zero waste" industry in the twenty-first century, and is considered to be one of the major trends for the future development of agriculture. However, the low nitrogen utilization efficiency (NUE) restricted its widely application. To date, many attempts have been conducted to improve its NUE. In the present study, effect of micro- and macro-nutrient addition on performance of tilapia-pak choi aquaponics was investigated. Results showed that the addition of micro- and macro-nutrients improved the growth of plant directly and facilitated fish physiology indirectly, which subsequently increased NUE of aquaponics from 40.42 to 50.64%. In addition, remarkable lower total phosphorus concentration was obtained in aquaponics with micro- and macro-nutrient addition, which was attributed to the formation of struvite. Most of the added micro-nutrients were enriched in plant root, while macro-nutrients mainly existed in water. Moreover, no enrichment of micro- and macro-nutrients in aquaponic products (i.e., fish and plant leaves) was observed, indicating that it had no influence on food safety. The findings here reported manifest that appropriate addition of micro- and macro-nutrients to aquaponics is necessary, and would improve its economic feasibility.

Micro and macro benefits of random investments in financial markets

Biondo, A. E.; Pluchino, A.; Rapisarda, A.

2014-10-01

In this paper, making use of recent statistical physics techniques and models, we address the specific role of randomness in financial markets, both at the micro and the macro level. In particular, we review some recent results obtained about the effectiveness of random strategies of investment, compared with some of the most used trading strategies for forecasting the behaviour of real financial indexes. We also push forward our analysis by means of a self-organised criticality model, able to simulate financial avalanches in trading communities with different network topologies, where a Pareto-like power law behaviour of wealth spontaneously emerges. In this context, we present new findings and suggestions for policies based on the effects that random strategies can have in terms of reduction of dangerous financial extreme events, i.e. bubbles and crashes.

Patient involvement in healthcare decisions has grown in Brazil at three different levels: 1) the macro level, which includes the patient actively influencing legislation and regulation of medical care as well as political changes in the process of care itself; 2) the meso level, which includes institutions that aim to improve information, empowerment and counseling to patients, and 3) the micro level, which focuses on the actual decision-making process that takes place within patient-physician encounter. In Brazil, the macro and meso levels are stronger than the micro one. In this paper, the practical efforts to engage patients in the center of their own care are presented. In order to do that, an overview on the National Humanization Policy and the Brazilian patient's movement is provided. Copyright © 2017. Published by Elsevier GmbH.

Educational decentralization, public spending, and social justice in Nigeria

NASA Astrophysics Data System (ADS)

Geo-Jaja, Macleans A.

2007-01-01

This study situates the process of educational decentralization in the narrower context of social justice. Its main object, however, is to analyze the implications of decentralization for strategies of equity and social justice in Nigeria. It starts from the premise that the early optimism that supported decentralization as an efficient and effective educational reform tool has been disappointed. The author maintains that decentralization — on its own — cannot improve education service delivery, the capacities of subordinate governments, or the integration of social policy in broader development goals. If the desired goals are to be met, public spending must be increased, greater tax revenues must be secured, and macro-economic stabilization must be achieved without re-instituting the welfare state.

Functioning information in the learning health system.

Stucki, Gerold; Bickenbach, Jerome

2017-02-01

In this methodological note on applying the ICF in rehabilitation, we introduce functioning information as fundamental for the "learning health system" and the continuous improvement of the health system's response to people's functioning needs by means of the provision of rehabilitation. A learning health system for rehabilitation operates at the micro-level of the individual patient, meso-level of operational management, and the macro-level of policy that guides rehabilitation programming. All three levels rely on the capacity of the informational system of the health system for standardized documentation and coding of functioning information, and the development of national rehabilitation quality management systems. This methodological note describes how functioning information is used for the continuous improvement of functioning outcomes in a learning health system across these three levels.

Health Sector Reform and Social Determinants of Health: building up theoretical and methodological interconnections to approach complex global challenges.

PubMed

Junior, Garibaldi Dantas Gurgel

2014-01-01

Health Sector Reform and Social Determinants of Health are central issues for the current international policy debate, considering the turbulent scenario and the threat of economic recession in a global scale. Although these themes have been discussed for a long time, three major issues still calls the attention of the scientific community and health policymakers. The first one is the matter of how to approach scientifically the intricate connections between them in order to understand the consequences of policies for healthcare services, once this debate will become much more tensioned in the coming years. The second one is the lack of explanatory frameworks to investigate the policies of reform strategies, simultaneously observed in a variety of countries within distinct health services, which aim to achieve multiple and contradictory goals vis-à-vis the so-called social determinants of health. The third one is the challenge that governments face in developing and sustaining equitable health services, bearing in mind the intense political dispute behind the health sector reform processes. This article discusses an all-embracing theoretical and methodological scheme to address these questions. The aim is to connect macro- and middle-range theories to examine Social Determinants and Health Sector Reform interdependent issues, with view to developing new knowledge and attaining scientific understanding upon the role of universal and equitable healthcare systems, in order to avoid deepening economic crises.

The third population boom and corresponding macro-policies.

Tian, X

China's birth peak between 1962-1973, and the expected 3rd peak beginning in 1986 has and will create a need for better, stable family planning measures; economic planning between 1990 and 2020 needs to accommodate the working population which in 2010 is expected to be 71.4% of the population (956 million); and a macro-strategic policy needs to be developed of the elderly who may constitute 17.44% of the population. The aging trend in China's working age population is expected to rise so rapidly that in 48 years, between 1982 and 2040, the over 65 population will quadruple ( a process in developed countries usually taking 80 years), thus creating a significant impact on a society with a low level of economic development. It is suggested that along with the growth in the national economy should come a state-provided welfare and retirement system, with reforms necessary to generate the additional income for elderly support; it is important that the cultural pattern of family care of the elderly remain intact. Assisting the able elderly in earning income in the service sector is encouraged. China's population has historically undergone 2 peak growth periods, between 1685 and 1830 with a 1% growth rate and between 1949-89 with an annual growth rate of 1.8%. The 2nd period is marked by 2 smaller peaks, one between 1953- 1957 with a growth rate of 2.38% and 1962-73 with a growth rate of 2.56%. A decline after 1974 changed to another upward cycle in 1986 with an increase to a 1.43 % growth rate expected to continue to 1996. The 1st peak between 1953-57 has already affected population control and the job market, and the fecund population is of concern because of the absolute size of the population, and because the planned limit for population growth of 1.2 billion by the year 2000 may be exceeded; and the projected rates, which have been increasing as expected, mean a population of 1.5 billion by 2050.

Agilent GC-MS MSD Chemstation offers automated library search report for toxicological screening using total ion chromatogram (TIC) and mass spectroscopy in normal mode. Numerous peaks appear in the chromatogram of biological specimen such as blood or urine and often large migrating peaks obscure small target peaks, in addition, any target peaks of low abundance regularly give wrong library search result or low matching score. As a result, retention time and mass spectrum of all the peaks in the chromatogram have to be checked to see if they are relevant. These repeated actions are very tedious and time-consuming to toxicologists. MSD Chemstation software operates using a number of macro files which give commands and instructions on how to work on and extract data from the chromatogram and spectroscopy. These macro files are developed by the own compiler of the software. All the original macro files can be modified and new macro files can be added to the original software by users. To get more accurate results with more convenient method and to save time for data analysis, we developed new macro files for reports generation and inserted new menus in the Enhanced Data Analysis program. Toxicological screening reports generated by these new macro files are in text mode or graphic mode and these reports can be generated with three different automated subtraction options. Text reports have Brief mode and Full mode and graphic reports have the option with or without mass spectrum mode. Matched mass spectrum and matching score for detected compounds are printed in reports by modified library searching modules. We have also developed an independent application program named DrugMan. This program manages drug groups, lists and parameters that are in use in MSD Chemstation. The incorporation of DrugMan with modified macro modules provides a powerful tool for toxicological screening and save a lot of valuable time on toxicological work. (c) 2010 Elsevier Ireland Ltd.

Iranian Nurses’ Status in Policymaking for Nursing in Health System: A Qualitative Content Analysis

2015-01-01

Presence of nurses in policy making will result improvement of nursing practice, and increase qualification of patients’ care, but still few nurses are involved in policy debates and health reforms and their status in policy making for nursing is not clear. The aim of this study was to elucidate Iranian nurses’ status in policy making for nursing in health system. This is a qualitative study. Using purposive sampling 22 participants were interviewed to gain deep understanding from the phenomenon of status of nurses in policy making. Of these 2 were not nurses but the members of Iran’s council for health policy making. Data were analyzed by employing conventional content analysis. Nurses’ status in policy making declared base on the implications of three main themes including “the policy making framework”, “perceived status of nurses in policy making”, and “the manner of nurses’ participation in policy making”. The conclusion of the present study is that Policy making for nursing is a subcategory of Iran’s macro health policies. What made the status of nurses more efficient in policy making for nursing was their practice and rate of participation in the appointed positions and the society. Results of this study represented major points of weakness in nursing policies and some recommendations for modifications. PMID:26089996

In 2013, Hafner and Shiffman applied Kingdon's public policy process model to explain the emergence of global attention to health system strengthening (HSS). They questioned, however, HSS's sustainability on the global health policy agenda, citing various concerns. Guided by the Grindle and Thomas interactive model of policy implementation, we advance and elaborate a proposition: a confluence of developments will contribute to maintaining HSS's prominent place on the agenda until at least 2030. Those developments include (1) technical, managerial, financial, and political responses to unpredictable public health crises that imperil the routine functioning of health systems, such as the 2014-2015 Ebola virus disease (Ebola) epidemic in West Africa; (2) similar responses to non-crisis situations requiring fully engaged, robust health systems, such as the pursuit of the new Sustainable Development Goal for health (SDG3); and (3) increased availability of new knowledge about system change at macro, meso, and micro levels and its effects on people's health and well-being. To gauge the accuracy of our proposition, we carried out a speculative assessment of credible threats to our premise by discussing all of the Hafner-Shiffman concerns. We conclude that (1) the components of our proposition and other forces that have the potential to promote continuing attention to HSS are of sufficient strength to counteract these concerns, and (2) prospective monitoring of HSS agenda status and further research on agenda sustainability can increase confidence in our threat assessment. © The Author 2017.

Parenthood and Happiness: Effects of Work-Family Reconciliation Policies in 22 OECD Countries.

PubMed

Glass, Jennifer; Simon, Robin W; Andersson, Matthew A

2016-11-01

The recent proliferation of studies examining cross-national variation in the association between parenthood and happiness reveal accumulating evidence of lower levels of happiness among parents than nonparents in most advanced industrialized societies. Conceptualizing parenting as a stressor buffered by institutional support, we hypothesize that parental status differences in happiness are smaller in countries providing more resources and support to families. Our analyses of the European Social Surveys (ESS) and International Social Survey Programme (ISSP) reveal considerable variation in the parenthood gap in happiness across countries, with the U.S. showing the largest disadvantage of parenthood. We also find that more generous family policies, particularly paid time off and childcare subsidies, are associated with smaller disparities in happiness between parents and non-parents. Moreover, the policies that augment parental happiness do not reduce the happiness of nonparents. Our results shed light on macro-level causes of emotional processes, with important implications for public policy.

A structuration framework for bridging the macro-micro divide in health-care governance.

PubMed

Bodolica, Virginia; Spraggon, Martin; Tofan, Gabriela

2016-08-01

Extant studies demonstrate that macro (hierarchical) and micro (relational) governance initiatives in health-care settings continue to be developed in isolation rather than interactively. Government-driven hierarchical governance endeavours that guide health-care reforms and medical practice are disconnected from micro-level physician-patient interactions being unable to account for patient preferences in the macro-level policymaking. We undertake a review of the recent literature to couch our argument for a unified governance framework for bridging the macro-micro divide in medical contexts. Adopting an interdisciplinary approach to health-care delivery, we maintain that the (strong) structuration theory provides a fruitful opportunity for narrowing the gap between hierarchical and relational governance. Emphasizing the coexistence of institutional structures and human agency, the (strong) structuration theory elucidates how macro and micro governance devices shape each other's structure via mutually reinforcing cycles of influence. Micro-level encounters between patients and physicians give rise to social structures that constitute the constraining and enabling forces through which macro-level health-care infrastructures are altered and reproduced over time. Permitting to illustrate how patients' agency can effectively emerge from complex networks of clinical trajectories, the advanced structuration framework for macro-micro governance integration avoids the extremes of paternalism and autonomy through a balanced consideration of professional judgement and patient preferences. The macro-micro integration of governance efforts is a critical issue in both high-income states, where medical institutions attempt to deploy substantial realignment efforts, and developing nations, which are lagging behind due to leadership weaknesses and lower levels of governmental investment. A key priority for regulators is the identification of relevant systems to support this holistic governance by providing clinicians with needed resources for focusing on patient advocacy and installing enabling mechanisms for incorporating patients' inputs in health-care reforms and policymaking. © 2015 John Wiley & Sons Ltd.

Globalization as a driver or bottleneck for sustainable development: some empirical, cross-national reflections on basic issues of international health policy and management.

PubMed

Tausch, Arno

2013-08-01

This article looks at the long-term, structural determinants of environmental and public health performance in the world system. In multiple standard ordinary least squares (OLS) regression models, we tested the effects of 26 standard predictor variables, including the 'four freedoms' of goods, capital, labour and services, on the following indicators of sustainable development and public health: avoiding net trade of ecological footprint global hectare (gha) per person; avoiding high carbon emissions per million US dollars GDP; avoiding high CO2 per capita (gha/cap); avoiding high ecological footprint per capita; avoiding becoming victim of natural disasters; a good performance on the Environmental Performance Index (EPI); a good performance on the Happy Life Years (HLYs) scale; and a good performance on the Happy Planet Index (HPI). Our research showed that the apprehensions of quantitative research, critical of neo-liberal globalization, are fully vindicated by the significant negative environmental and public health effects of the foreign savings rate. High foreign savings are indeed a driver of global footprint, and are a blockade against a satisfactory HPI performance. The new international division of labour is one of the prime drivers of high CO2 per capita emissions. Multinational Corporation (MNC) penetration, the master variable of most quantitative dependency theories, blocks EPI and several other socially important processes. Worker remittances have a significant positive effect on the HPI, and HLYs. We re-analysed the solid macro-political and macro-sociological evidence on a global scale, published in the world's leading peer-reviewed social science, ecological and public health journals, which seem to indicate that there are contradictions between unfettered globalization and unconstrained world economic openness and sustainable development and public health development. We suggest that there seems to be a strong interaction between 'transnational capitalist penetration' and 'environmental and public health degradation'. Global policy-making finally should dare to take the globalization-critical organizations of 'civil society' seriously. This conclusion not only holds for the countries of the developed "West", but also, increasingly, for the growing democracy and civil society movements around the globe, in countries as diverse as Brazil, Russia, China, or ever larger parts of the Muslim world.

Methods: In multiple standard ordinary least squares (OLS) regression models, we tested the effects of 26 standard predictor variables, including the ‘four freedoms’ of goods, capital, labour and services, on the following indicators of sustainable development and public health: avoiding net trade of ecological footprint global hectare (gha) per person; avoiding high carbon emissions per million US dollars GDP; avoiding high CO2 per capita (gha/cap); avoiding high ecological footprint per capita; avoiding becoming victim of natural disasters; a good performance on the Environmental Performance Index (EPI); a good performance on the Happy Life Years (HLYs) scale; and a good performance on the Happy Planet Index (HPI). Results: Our research showed that the apprehensions of quantitative research, critical of neo-liberal globalization, are fully vindicated by the significant negative environmental and public health effects of the foreign savings rate. High foreign savings are indeed a driver of global footprint, and are a blockade against a satisfactory HPI performance. The new international division of labour is one of the prime drivers of high CO2 per capita emissions. Multinational Corporation (MNC) penetration, the master variable of most quantitative dependency theories, blocks EPI and several other socially important processes. Worker remittances have a significant positive effect on the HPI, and HLYs. Conclusion: We re-analysed the solid macro-political and macro-sociological evidence on a global scale, published in the world’s leading peer-reviewed social science, ecological and public health journals, which seem to indicate that there are contradictions between unfettered globalization and unconstrained world economic openness and sustainable development and public health development. We suggest that there seems to be a strong interaction between ‘transnational capitalist penetration’ and ‘environmental and public health degradation’. Global policy-making finally should dare to take the globalization-critical organizations of ‘civil society’ seriously. This conclusion not only holds for the countries of the developed “West”, but also, increasingly, for the growing democracy and civil society movements around the globe, in countries as diverse as Brazil, Russia, China, or ever larger parts of the Muslim world.

Agricultural Model for the Nile Basin Decision Support System

NASA Astrophysics Data System (ADS)

van der Bolt, Frank; Seid, Abdulkarim

2014-05-01

To analyze options for increasing food supply in the Nile basin the Nile Agricultural Model (AM) was developed. The AM includes state-of-the-art descriptions of biophysical, hydrological and economic processes and realizes a coherent and consistent integration of hydrology, agronomy and economics. The AM covers both the agro-ecological domain (water, crop productivity) and the economic domain (food supply, demand, and trade) and allows to evaluate the macro-economic and hydrological impacts of scenarios for agricultural development. Starting with the hydrological information from the NileBasin-DSS the AM calculates the available water for agriculture, the crop production and irrigation requirements with the FAO-model AquaCrop. With the global commodity trade model MAGNET scenarios for land development and conversion are evaluated. The AM predicts consequences for trade, food security and development based on soil and water availability, crop allocation, food demand and food policy. The model will be used as a decision support tool to contribute to more productive and sustainable agriculture in individual Nile countries and the whole region.

Use of national clinical databases for informing and for evaluating health care policies.

PubMed

Black, Nick; Tan, Stefanie

2013-02-01

Policy-makers and analysts could make use of national clinical databases either to inform or to evaluate meso-level (organisation and delivery of health care) and macro-level (national) policies. Reviewing the use of 15 of the best established databases in England, we identify and describe four published examples of each use. These show that policy-makers can either make use of the data itself or of research based on the database. For evaluating policies, the major advantages are the huge sample sizes available, the generalisability of the data, its immediate availability and historic information. The principal methodological challenges involve the need for risk adjustment and time-series analysis. Given their usefulness in the policy arena, there are several reasons why national clinical databases have not been used more, some due to a lack of 'push' by their custodians and some to the lack of 'pull' by policy-makers. Greater exploitation of these valuable resources would be facilitated by policy-makers' and custodians' increased awareness, minimisation of legal restrictions on data use, improvements in the quality of databases and a library of examples of applications to policy.

Macropsychology, policy, and global health.

PubMed

MacLachlan, Malcolm

2014-11-01

In this article I argue for the development of a macro perspective within psychology, akin to that found in macroeconomics. Macropsychology is the application of psychology to factors that influence the settings and conditions of our lives. As policy concerns the strategic allocation of resources—who gets what and why?—it should be an area of particular interest for macropsychology. I review ways in which psychology may make a contribution to policy within the field of global health. Global health emphasizes human rights, equity, social inclusion, and empowerment; psychology has much to contribute to these areas, both at the level of policy and practice. I review the sorts of evidence and other factors that influence policymakers, along with the content, process, and context of policymaking, with a particular focus on the rights of people with disabilities in the low- and middle-income countries of Africa and Asia. These insights are drawn from collaborations with a broad range of practitioners, governments, United Nations agencies, civil society organizations, the private sector and researchers. Humanitarian work psychology is highlighted as an example of a new area of psychology that embraces some of the concerns of macropsychology. The advent of "big data" presents psychology with an opportunity to ask new types of questions, and these should include "understanding up," or how psychological factors can contribute to human well-being, nationally and globally.

Analysis of Macro-micro Simulation Models for Service-Oriented Public Platform: Coordination of Networked Services and Measurement of Public Values

NASA Astrophysics Data System (ADS)

Kinoshita, Yumiko

When service sectors are a major driver for the growth of the world economy, we are challenged to implement service-oriented infrastructure as e-Gov platform to achieve further growth and innovation for both developed and developing countries. According to recent trends in service industry, it is clarified that main factors for the growth of service sectors are investment into knowledge, trade, and the enhanced capacity of micro, small, and medium-sized enterprises (MSMEs). In addition, the design and deployment of public service platform require appropriate evaluation methodology. Reflecting these observations, this paper proposes macro-micro simulation approach to assess public values (PV) focusing on MSMEs. Linkage aggregate variables (LAVs) are defined to show connection between macro and micro impacts of public services. As a result, the relationship of demography, business environment, macro economy, and socio-economic impact are clarified and their values are quantified from the behavioral perspectives of citizens and firms.

Development of Healthy Cities networks in Europe.

PubMed

Goepel, Eberhard

2007-01-01

The Healthy Cities network in Europe was inspired by the Ottawa Charter for Health Promotion when it was launched in 1987. The networking process was initiated by the WHO Regional Office for Europe, but developed its own dynamics in different European countries during a time marked by fundamental political transformations in many of the countries of Eastern Europe. The networks then connected with the 'Local Agenda 21' and the 'Sustainable Cities and Towns Campaign' to create a new and broader programmatic agenda at the local level. In particular, the ''Aalborg plus 10 - commitments"--of local governments in 2004 have the potential to inspire a new phase of participatory and sustainable policies at the level of local communities in Europe. However, the extent to which these initiatives will influence the macro-politics of the European Union towards a proclaimed "Europe of Citizens" remains to be watched carefully during the coming years.

As part of analysis support for FCTO, Sandia assesses the factors that influence the future of FCEVs and Hydrogen in the US vehicle fleet. Using ParaChoice, we model competition between FCEVs, conventional vehicles, and other alternative vehicle technologies in order to understand the drivers and sensitivities of adoption of FCEVs. ParaChoice leverages existing tools such as Autonomie (Moawad et al., 2016), AEO (U.S. Energy Information Administration, 2016), and the Macro System Model (Ruth et al., 2009) in order to synthesize a complete picture of the co-evolution of vehicle technology development, energy price evolution, and hydrogen production and pricing, with consumermore » demand for vehicles and fuel. We then assess impacts of FCEV market penetration and hydrogen use on green- house gas (GHG) emissions and petroleum consumption, providing context for the role of policy, technology development, infrastructure, and consumer behavior on the vehicle and fuel mix through parametric and sensitivity analyses.« less

In the past decade, an international consensus on the value of well-functioning systems has driven considerable health systems research. This research falls into two broad categories. The first provides conceptual frameworks that take complex healthcare systems and create simplified constructs of interactions and functions. The second focuses on granular inputs and outputs. This paper presents a novel translational mapping tool - the University of California, San Francisco mapping tool (the Tool) - which bridges the gap between these two areas of research, creating a platform for multi-country comparative analysis. Using the Murray-Frenk framework, we create a macro-level representation of a country's structure, focusing on how it finances and delivers healthcare. The map visually depicts the fundamental policy questions in healthcare system design: funding sources and amount spent through each source, purchasers, populations covered, provider categories; and the relationship between these entities. We use the Tool to provide a macro-level comparative analysis of the structure of India's and Thailand's healthcare systems. As part of the systems strengthening arsenal, the Tool can stimulate debate about the merits and consequences of different healthcare systems structural designs, using a common framework that fosters multi-country comparative analyses. © The Author 2017.

Macro influencers of electronic health records adoption.

PubMed

Raghavan, Vijay V; Chinta, Ravi; Zhirkin, Nikita

2015-01-01

While adoption rates for electronic health records (EHRs) have improved, the reasons for significant geographical differences in EHR adoption within the USA have remained unclear. To understand the reasons for these variations across states, we have compiled from secondary sources a profile of different states within the USA, based on macroeconomic and macro health-environment factors. Regression analyses were performed using these indicator factors on EHR adoption. The results showed that internet usage and literacy are significantly associated with certain measures of EHR adoption. Income level was not significantly associated with EHR adoption. Per capita patient days (a proxy for healthcare need intensity within a state) is negatively correlated with EHR adoption rate. Health insurance coverage is positively correlated with EHR adoption rate. Older physicians (>60 years) tend to adopt EHR systems less than their younger counterparts. These findings have policy implications on formulating regionally focused incentive programs.

Towards a higher priority for health on the development agenda.

PubMed

Yach, D; von Schirnding, Y E

1994-01-01

Over the last few years major international agencies (particularly the World Health Organisation and the World Bank) have increasingly recognised that investing in health is crucial for development. Development policies have the potential to enhance or impede progress in achieving Health for All. At the macro-economic level it is broadly recognised that the state of the economy of a country has a strong influence on its health level. The growing number of the population below the poverty line in sub-Saharan Africa is expected to have a substantial impact on health in the future. Further, structural adjustment programmes' impact on health has yet to be adequately evaluated. Rapid population growth in sub-Saharan Africa needs to be innovatively addressed as a matter of extreme urgency. The education of women is strongly related to child survival. Over the next few years the prospects for global disarmament are increasing. Options for using both the technology, financial savings, and personnel for improving health need to be investigated. A broader range of policy options for health needs to be considered by governments. A greater focus on information, education, and communication for health is needed that draws upon both the private and the public sector; greater use of regulation and legislation as solid policy instruments, for example, for pollution control, and banning tobacco and alcohol advertising, is required. Financial strategies using a combination of taxes and subsidies have not been adequately used in developing countries. The previous emphasis on urban-based expensive hospitals has proved to be inappropriate, resulting in severe inefficiency and inequity in the health systems of developing countries. Greater attention must be given to funding those areas with a high potential for positive externalities and that yield public goods. The final policy instrument involves using research to extend the options for intervention choice.

A macro perspective for client-centred practice in curricula: Critique and teaching methods.

PubMed

Fleming-Castaldy, Rita P

2015-07-01

Client-centred practice is often eclipsed by social, economic, and political inequities. Ignoring these realities obstructs clients' goal attainment. The author advocates for the integration of a macro perspective inclusive of participation barriers and supports in occupational therapy curricula and seeks to motivate educators to adopt teaching approaches that develop students' abilities to address the complexities of client-centred practice. This article integrates a critical analysis of the literature on client-centred practice with reflexivity on disability studies and autoethnography. Educational standards require students to learn about the social, economic, and political contexts that impact on client-centred practice and the need for advocacy to enable participation. Theoretical support of a macro perspective for client-centred practice is strongly evident in the literature. Information on methods for teaching students how to actualize these concepts in practice is scant. Thus, strategies to inform the integration of a macro perspective into curricula and concrete activities to develop students' competencies for empowered client-centred practice are required. Educators have an ethical responsibility to critique their pedagogy to determine whether they are adequately preparing students for client-centred practice. The focus must move from teaching a micro perspective of client-centred practice to a macro perspective that enables occupational justice and empowerment.

The main objective of this study is to analyse and design an optimum cooling system for macro compartment. Current product of the refrigerator is not specified for single function and not compact in size. Hence, a refrigeration system using refrigerant R134a is aimed to provide instant cooling in a macro compartment with sizing about 150 × 150 × 250 mm. The macro compartment is purposely designed to fit a bottle or drink can, which is then cooled to a desired drinking temperature of about 8°C within a period of 1 minute. The study is not only concerned with analysing of heat load of the macro compartment containing drink can, but also focused on determining suitable heat exchanger volume for both evaporator and condenser, calculating compressor displacement value and computing suitable resistance value of the expansion valve. Method of optimization is used to obtain the best solution of the problem. Mollier diagram is necessary in the process of developing the refrigeration system. Selection of blower is made properly to allow air circulation and to increase the flow rate for higher heat transfer rate. Property data are taken precisely from thermodynamic property tables. As the main four components, namely condenser, compressor, evaporator and expansion valve are fully developed, the refrigeration system is complete.

Navigating catastrophes: Local but not global optimisation allows for macro-economic navigation of crises

NASA Astrophysics Data System (ADS)

Harré, Michael S.

2013-02-01

Two aspects of modern economic theory have dominated the recent discussion on the state of the global economy: Crashes in financial markets and whether or not traditional notions of economic equilibrium have any validity. We have all seen the consequences of market crashes: plummeting share prices, businesses collapsing and considerable uncertainty throughout the global economy. This seems contrary to what might be expected of a system in equilibrium where growth dominates the relatively minor fluctuations in prices. Recent work from within economics as well as by physicists, psychologists and computational scientists has significantly improved our understanding of the more complex aspects of these systems. With this interdisciplinary approach in mind, a behavioural economics model of local optimisation is introduced and three general properties are proven. The first is that under very specific conditions local optimisation leads to a conventional macro-economic notion of a global equilibrium. The second is that if both global optimisation and economic growth are required then under very mild assumptions market catastrophes are an unavoidable consequence. Third, if only local optimisation and economic growth are required then there is sufficient parametric freedom for macro-economic policy makers to steer an economy around catastrophes without overtly disrupting local optimisation.

Universal health coverage at the macro level: Synthetic control evidence from Thailand.

2017-01-01

As more and more countries are moving towards Universal Health Coverage (UHC), it is important to understand the macro level or aggregate impacts of such a policy. We use synthetic control methods to study the impact of UHC, introduced in Thailand in 2001, on various macroeconomic and health outcomes. Thailand is compared to a weighted average of control countries in terms of aggregate health financing indicators, aggregate health outcomes and economic performance, over the period 1995 to 2012. Our results suggest that UHC helps alleviate the financial consequences of illnesses. The estimated treatment effect of UHC on out-of-pocket payments as a percentage of overall health expenditures is negative 13 percentage points and its effect on annual government per capita health spending is US$ 79. We detect a smaller effect of US$ 60.8 on total health spending per capita which appears with a lag. We document positive health effects as captured by reductions in infant and child mortality. We do not find any effect on GDP and the share of the government budget devoted to health. Overall, our results complement micro evidence based on within country variation. The counterfactual design implemented here may be used to inform other countries on the macro level repercussions of UHC. Copyright © 2016. Published by Elsevier Ltd.

Model-based system analysis is an important tool for evaluating the potential and impacts of biofuels, and for drafting biofuels technology roadmaps and targets. The broad reach of the biofuels supply chain requires that biofuels system analyses span a range of disciplines, including agriculture/forestry, energy, economics, and the environment. Here we reviewed various models developed for or applied to modeling biofuels, and presented a critical analysis of Agriculture/Forestry System Models, Energy System Models, Integrated Assessment Models, Micro-level Cost, Energy and Emission Calculation Models, and Specific Macro-level Biofuel Models. We focused on the models' strengths, weaknesses, and applicability, facilitating the selection of a suitable type of model for specific issues. Such an analysis was a prerequisite for future biofuels system modeling, and represented a valuable resource for researchers and policy makers.

Finite Macro-Element Mesh Deformation in a Structured Multi-Block Navier-Stokes Code

NASA Technical Reports Server (NTRS)

Bartels, Robert E.

2005-01-01

A mesh deformation scheme is developed for a structured multi-block Navier-Stokes code consisting of two steps. The first step is a finite element solution of either user defined or automatically generated macro-elements. Macro-elements are hexagonal finite elements created from a subset of points from the full mesh. When assembled, the finite element system spans the complete flow domain. Macro-element moduli vary according to the distance to the nearest surface, resulting in extremely stiff elements near a moving surface and very pliable elements away from boundaries. Solution of the finite element system for the imposed boundary deflections generally produces smoothly varying nodal deflections. The manner in which distance to the nearest surface has been found to critically influence the quality of the element deformation. The second step is a transfinite interpolation which distributes the macro-element nodal deflections to the remaining fluid mesh points. The scheme is demonstrated for several two-dimensional applications.

Multi-site health sciences research is becoming more common, as it enables investigation of rare outcomes and diseases and new healthcare innovations. Multi-site research usually involves the transfer of large amounts of research data between collaborators, which increases the potential for accidental disclosures of protected health information (PHI). Standard protocols for preventing release of PHI are extremely vulnerable to human error, particularly when the shared data sets are large. To address this problem, we developed an automated program (SAS macro) to identify possible PHI in research data before it is transferred between research sites. The macro reviews all data in a designated directory to identify suspicious variable names and data patterns. The macro looks for variables that may contain personal identifiers such as medical record numbers and social security numbers. In addition, the macro identifies dates and numbers that may identify people who belong to small groups, who may be identifiable even in the absences of traditional identifiers. Evaluation of the macro on 100 sample research data sets indicated a recall of 0.98 and precision of 0.81. When implemented consistently, the macro has the potential to streamline the PHI review process and significantly reduce accidental PHI disclosures.

This paper represents the Department of Energy Office of Nonproliferation Research and Development (NA-22) Simulations, Algorithms and Modeling (SAM) Program's first effort to identify and frame analytical methods and tools to aid export control professionals in effectively predicting proliferation intent; a complex, multi-step and multi-agency process. The report focuses on analytical modeling methodologies that alone, or combined, may improve the proliferation export control license approval process. It is a follow-up to an earlier paper describing information sources and environments related to international nuclear technology transfer. This report describes the decision criteria used to evaluate modeling techniques and tools to determinemore » which approaches will be investigated during the final 2 years of the project. The report also details the motivation for why new modeling techniques and tools are needed. The analytical modeling methodologies will enable analysts to evaluate the information environment for relevance to detecting proliferation intent, with specific focus on assessing risks associated with transferring dual-use technologies. Dual-use technologies can be used in both weapons and commercial enterprises. A decision-framework was developed to evaluate which of the different analytical modeling methodologies would be most appropriate conditional on the uniqueness of the approach, data availability, laboratory capabilities, relevance to NA-22 and Office of Arms Control and Nonproliferation (NA-24) research needs and the impact if successful. Modeling methodologies were divided into whether they could help micro-level assessments (e.g., help improve individual license assessments) or macro-level assessment. Macro-level assessment focuses on suppliers, technology, consumers, economies, and proliferation context. Macro-level assessment technologies scored higher in the area of uniqueness because less work has been done at the macro level. An approach to developing testable hypotheses for the macro-level assessment methodologies is provided. The outcome of this works suggests that we should develop a Bayes Net for micro-level analysis and continue to focus on Bayes Net, System Dynamics and Economic Input/Output models for assessing macro-level problems. Simultaneously, we need to develop metrics for assessing intent in export control, including the risks and consequences associated with all aspects of export control.« less

Interactions between macro-algal mats and invertebrates in the Ythan estuary, Aberdeenshire, Scotland

NASA Astrophysics Data System (ADS)

Raffaelli, D.

2000-07-01

Blooms of opportunistic green macro-algae are a common feature of coastal areas and their effects on mudflat invertebrates can be dramatic. On the Ythan estuary, Aberdeenshire, Scotland, we have carried out a number of manipulative field experiments designed to evaluate the effects on invertebrates of different species of macro-algae with contrasting ecologies, and the effects of invertebrates on the development of the blooms. Macro-algal mats were found to have dramatic nega- tive effects on the density of the amphipod Corophium volutator, with higher algal biomasses having greater impact. The mechanism for this interaction seems to be interference by the algal filaments with the feeding behaviour of the amphipod. In contrast, the polychaete Capitella spp. increases in abundance under macro-algal mats due to enrichment of the sediment with organic material. These two interactions are seen at all scales, in areas of less than 1 m2 to the scale of the entire estuary, irrespective of the species composition of the macro- algal mats. Bioturbation by Corophium and grazing by the snail Hydrobia ulvae had little effect on macro-algal biomass, but there were less algae when the polychaete Nereis diversicolor was present. The most significant interaction in this system is the pronounced negative impact of algal mats on the abundance of Corophium, probably the most important invertebrate species in the diets of the estuary's shorebirds, fish and epibenthic crustaceans.

Purpose TUNEL assay is widely used to evaluate cell death. Quantification of TUNEL-positive (TUNEL+) cells in tissue sections is usually performed manually, ideally by two masked observers. This process is time consuming, prone to measurement errors, and not entirely reproducible. In this paper, we describe an automated quantification approach to address these difficulties. Methods We developed an ImageJ macro to quantitate cell death by TUNEL assay in retinal cross-section images. The script was coded using IJ1 programming language. To validate this tool, we selected a dataset of TUNEL assay digital images, calculated layer area and cell count manually (done by two observers), and compared measurements between observers and macro results. Results The automated macro segmented outer nuclear layer (ONL) and inner nuclear layer (INL) successfully. Automated TUNEL+ cell counts were in-between counts of inexperienced and experienced observers. The intraobserver coefficient of variation (COV) ranged from 13.09% to 25.20%. The COV between both observers was 51.11 ± 25.83% for the ONL and 56.07 ± 24.03% for the INL. Comparing observers' results with macro results, COV was 23.37 ± 15.97% for the ONL and 23.44 ± 18.56% for the INL. Conclusions We developed and validated an ImageJ macro that can be used as an accurate and precise quantitative tool for retina researchers to achieve repeatable, unbiased, fast, and accurate cell death quantitation. We believe that this standardized measurement tool could be advantageous to compare results across different research groups, as it is freely available as open source. PMID:26469755

Forms of benefit sharing in global health research undertaken in resource poor settings: a qualitative study of stakeholders' views in Kenya.

PubMed

Lairumbi, Geoffrey M; Parker, Michael; Fitzpatrick, Raymond; English, Michael C

2012-01-17

Increase in global health research undertaken in resource poor settings in the last decade though a positive development has raised ethical concerns relating to potential for exploitation. Some of the suggested strategies to address these concerns include calls for providing universal standards of care, reasonable availability of proven interventions and more recently, promoting the overall social value of research especially in clinical research. Promoting the social value of research has been closely associated with providing fair benefits to various stakeholders involved in research. The debate over what constitutes fair benefits; whether those that addresses micro level issues of justice or those focusing on the key determinants of health at the macro level has continued. This debate has however not benefited from empirical work on what stakeholders consider fair benefits. This study explores practical experiences of stakeholders involved in global health research in Kenya, over what benefits are fair within a developing world context. We conducted in-depth interviews with key informants drawn from within the broader health research system in Kenya including researchers from the mainstream health research institutions, networks and universities, teaching hospitals, policy makers, institutional review boards, civil society organisations and community representative groups.The range of benefits articulated by stakeholders addresses both micro and macro level concerns for justice by for instance, seeking to engage with interests of those facilitating research, and the broader systemic issues that make resource poor settings vulnerable to exploitation. We interpret these views to suggest a need for global health research to engage with current crises that face people in these settings as well as the broader systemic issues that produce them. Global health research should provide benefits that address both the micro and macro level issues of justice in order to forestall exploitation. Embracing the two is however challenging in terms of how the various competing interests/needs should be balanced ethically, especially in the absence of structures to guide the process. This challenge should point to the need for greater dialogue to facilitate value clarification among stakeholders.

Genetic variation for environmental sensitivity indicates that animals are genetically different in their response to environmental factors. Environmental factors are either identifiable (e.g. temperature) and called macro-environmental or unknown and called micro-environmental. The objectives of this study were to develop a statistical method to estimate genetic parameters for macro- and micro-environmental sensitivities simultaneously, to investigate bias and precision of resulting estimates of genetic parameters and to develop and evaluate use of Akaike's information criterion using h-likelihood to select the best fitting model. We assumed that genetic variation in macro- and micro-environmental sensitivities is expressed as genetic variance in the slope of a linear reaction norm and environmental variance, respectively. A reaction norm model to estimate genetic variance for macro-environmental sensitivity was combined with a structural model for residual variance to estimate genetic variance for micro-environmental sensitivity using a double hierarchical generalized linear model in ASReml. Akaike's information criterion was constructed as model selection criterion using approximated h-likelihood. Populations of sires with large half-sib offspring groups were simulated to investigate bias and precision of estimated genetic parameters. Designs with 100 sires, each with at least 100 offspring, are required to have standard deviations of estimated variances lower than 50% of the true value. When the number of offspring increased, standard deviations of estimates across replicates decreased substantially, especially for genetic variances of macro- and micro-environmental sensitivities. Standard deviations of estimated genetic correlations across replicates were quite large (between 0.1 and 0.4), especially when sires had few offspring. Practically, no bias was observed for estimates of any of the parameters. Using Akaike's information criterion the true genetic model was selected as the best statistical model in at least 90% of 100 replicates when the number of offspring per sire was 100. Application of the model to lactation milk yield in dairy cattle showed that genetic variance for micro- and macro-environmental sensitivities existed. The algorithm and model selection criterion presented here can contribute to better understand genetic control of macro- and micro-environmental sensitivities. Designs or datasets should have at least 100 sires each with 100 offspring.

Agricultural policy and sustainable livestock development.

PubMed

Schillhorn van Veen, T W

Future agricultural and rural development is, to a large extent, influenced by the projected food needs of 2.5 billion people expected to swell the world population by 2020. This increase will require more food in general and, in view of recent experience in East Asia, more animal products. To achieve this increase will require judicious use of resources, and trade, especially in those countries where natural resources are insufficient to support food production. Achieving food sufficiency in a sustainable manner is a major challenge for farmers, agro-industries, researchers and governments. The latter play an important role as many of the farmers' choices are, to a large extent, directed by government or supra-government, often through macro- and micro-economic policy. In many countries the economic, environmental, trade and agricultural policies have not been conducive to an agricultural development that is risk-free with respect to the environment, animal welfare or public health. The recent decline of government support in agriculture forced farmers in Western countries to think about more risk adverse agricultural practices and more efficient production systems. On the other hand, many countries in Eastern Europe and the former Soviet Union, as well as other developing countries, are still going through a painful process of adjustment to new market conditions. International banks and development agencies have a mandate to help developing countries, but are somewhat restricted both by needing to work directly with governments and by their perceived dogmatic approach to development. Changing policies do, now and in the future, also affect the development of animal disease control programmes, including the control of parasitic diseases. On the one hand there is an increasing interest in risk-free control practices, and on the other hand a demand for greater regulatory control over the production process. As parasitic diseases of animals are closely linked to the environment (i.e. grazing and waste management) and public health (i.e. parasitic zoonoses), the new interest in sustainable agriculture provides a challenge for those concerned with the control and prevention of animal parasitism.

A force-controllable macro-micro manipulator and its application to medical robots

NASA Technical Reports Server (NTRS)

Marzwell, Neville I.; Uecker, Darrin R.; Wang, Yulun

1994-01-01

This paper describes an 8-degrees-of-freedom macro-micro robot. This robot is capable of performing tasks that require accurate force control, such as polishing, finishing, grinding, deburring, and cleaning. The design of the macro-micro mechanism, the control algorithms, and the hardware/software implementation of the algorithms are described in this paper. Initial experimental results are reported. In addition, this paper includes a discussion of medical surgery and the role that force control may play. We introduce a new class of robotic systems collectively called Robotic Enhancement Technology (RET). RET systems introduce the combination of robotic manipulation with human control to perform manipulation tasks beyond the individual capability of either human or machine. The RET class of robotic systems offers new challenges in mechanism design, control-law development, and man/machine interface design. We believe force-controllable mechanisms such as the macro-micro structure we have developed are a necessary part of RET. Work in progress in the area of RET systems and their application to minimally invasive surgery is presented, along with future research directions.

This work presents method for performing precision macro-structure defects "tapers" and "up-tapers" written in conventional silica telecommunication multimode optical fibers by commercially available field fusion splicer with modified software settings and following writing fiber Bragg gratings over or near them. We developed technique for macrodefect geometry parameters estimation via analysis of photo-image performed after defect writing and displayed on fusion splicer screen. Some research results of defect geometry dependence on fusion current and fusion time values re-set in splicer program are represented that provided ability to choose their "the best" combination. Also experimental statistical researches concerned with "taper" and "up-taper" diameter stability as well as their insertion loss values during their writing under fixed corrected splicer program parameters were performed. We developed technique for FBG writing over or near macro-structure defect. Some results of spectral response measurements produced for short-length samples of multimode optical fiber with fiber Bragg gratings written over and near macro-defects prepared by using proposed technique are presented.

Inter-regional comparison of health-reform outcomes in south-eastern Europe (SEE). Macro-indicators were obtained from the WHO Health for All Database. Inter-regional comparison among post-Semashko, former Yugoslavia, and prior-1989-free-market SEE economies was conducted. United Nations Development Program Human Development Index growth was strongest among prior-free-market SEE, followed by former Yugoslavia and post-Semashko. Policy cuts to hospital beds and nursing-staff capacities were highest in post-Semashko. Physician density increased the most in prior-free-market SEE. Length of hospital stay was reduced in most countries; frequency of outpatient visits and inpatient discharges doubled in prior-free-market SEE. Fertility rates fell for one third in Post-Semashko and prior-free-market SEE. Crude death rates slightly decreased in prior-free-market-SEE and post-Semashko, while growing in the former Yugoslavia region. Life expectancy increased by 4 years on average in all regions; prior-free-market SEE achieving the highest longevity. Childhood and maternal mortality rates decreased throughout SEE, while post-Semashko countries recorded the most progress. Significant differences in healthcare resources and outcomes were observed among three historical health-policy legacies in south-eastern Europe. These different routes towards common goals created a golden opportunity for these economies to learn from each other.

This paper revisits three reports on ergonomic aspects of development initiatives taking place in Industrially Developing Countries (IDCs). These include a macro-ergonomics intervention in a habitation community in Cape Verde (aimed at designing solutions contributing to sustainable development), the evolution of poultry growers' control strategies as an integrative broiler operation is introduced in Mozambique, and a set of macro-ergonomic considerations related to the Agro Forestry Village Project in Mozambique. The paper seeks to set the reviewed development endeavors against the backdrop of the goals of ergonomics interventions. This reflection may inform development agents in future processes of design and implementation of integrated community and work systems transformation.

The purpose of this study was to examine key processes and supportive and inhibiting factors involved in the development, evolution, and sustainability of a child health network in rural Canada. This study contributes to a relatively new research agenda aimed at understanding inter-organizational and cross-sectoral health networks. These networks encourage collaboration focusing on complex issues impacting health - issues that individual agencies cannot effectively address alone. This paper presents an overview of the study findings. An explanatory qualitative case study approach examined the Network's 13-year lifespan. Data sources were documents and Network members, including regional and 71 provincial senior managers from 11 child and youth service sectors. Data were collected through 34 individual interviews and a review of 127 documents. Interview data were analyzed using framework analysis methods; Prior's approach guided document analysis. Three themes related to network development, evolution and sustainability were identified: (a) Network relationships as system triggers, (b) Network-mediated system responsiveness, and (c) Network practice as political. Study findings have important implications for network organizational development, collaborative practice, interprofessional education, public policy, and public system responsiveness research. Findings suggest it is important to explicitly focus on relationships and multi-level socio-political contexts, such as supportive policy environments, in understanding health networks. The dynamic interplay among the Network members; central supportive and inhibiting factors; and micro-, meso-, and macro-organizational contexts was identified.

Although the conditions and power relations of employment are known to be crucial health determinants for workers and their families, the nature of these relations and their effects on health have yet to be fully researched. Several types of employment--precarious employment in developed countries; informal sectors, child labor, slavery, and bonded labor in developing countries--expose workers to risky working conditions. Hazardous work and occupation-related diseases kill approximately 1,500 workers, globally, every day. Growing scientific evidence suggests that particular employment conditions, such as job insecurity and precarious employment, create adverse health effects; yet the limited number of studies and the poor quality of their methods prevent our understanding, globally, the complexity of employer-employee power relations, working conditions, levels of social protections, and the reality of employment-related health inequalities. This article introduces a special section on employment-related health inequalities, derived from the EMCONET approach, which focuses on (1) describing major methods and sources of information; (2) presenting theoretical models at the micro and macro levels; (3) presenting a typology of labor markets and welfare states worldwide; (4) describing the main findings in employment policies, including four key points for implementing strategies; and (5) suggesting new research developments, a policy agenda, and recommendations. This introduction includes a glossary of terms in the emerging area of employment conditions and health inequalities.

Managing protected health information in distributed research network environments: automated review to facilitate collaboration

PubMed Central

2013-01-01

Background Multi-site health sciences research is becoming more common, as it enables investigation of rare outcomes and diseases and new healthcare innovations. Multi-site research usually involves the transfer of large amounts of research data between collaborators, which increases the potential for accidental disclosures of protected health information (PHI). Standard protocols for preventing release of PHI are extremely vulnerable to human error, particularly when the shared data sets are large. Methods To address this problem, we developed an automated program (SAS macro) to identify possible PHI in research data before it is transferred between research sites. The macro reviews all data in a designated directory to identify suspicious variable names and data patterns. The macro looks for variables that may contain personal identifiers such as medical record numbers and social security numbers. In addition, the macro identifies dates and numbers that may identify people who belong to small groups, who may be identifiable even in the absences of traditional identifiers. Results Evaluation of the macro on 100 sample research data sets indicated a recall of 0.98 and precision of 0.81. Conclusions When implemented consistently, the macro has the potential to streamline the PHI review process and significantly reduce accidental PHI disclosures. PMID:23521861

Parenthood and Happiness: Effects of Work-Family Reconciliation Policies in 22 OECD Countries

PubMed Central

Glass, Jennifer; Simon, Robin W.; Andersson, Matthew A

2016-01-01

The recent proliferation of studies examining cross-national variation in the association between parenthood and happiness reveal accumulating evidence of lower levels of happiness among parents than nonparents in most advanced industrialized societies. Conceptualizing parenting as a stressor buffered by institutional support, we hypothesize that parental status differences in happiness are smaller in countries providing more resources and support to families. Our analyses of the European Social Surveys (ESS) and International Social Survey Programme (ISSP) reveal considerable variation in the parenthood gap in happiness across countries, with the U.S. showing the largest disadvantage of parenthood. We also find that more generous family policies, particularly paid time off and childcare subsidies, are associated with smaller disparities in happiness between parents and non-parents. Moreover, the policies that augment parental happiness do not reduce the happiness of nonparents. Our results shed light on macro-level causes of emotional processes, with important implications for public policy. PMID:28082749

Clinical research will increasingly play a core role in the evolution and growth of acute care surgery program development across the country. What constitutes an efficient and effective clinical research infrastructure in the current fiscal and academic environment remains obscure. We sought to characterize the effects of implementation of a multidisciplinary acute care research organization (MACRO) at a busy tertiary referral university setting. In 2008, to minimize redundancy and cost as well as to maximize existing resources promoting acute care research, MACRO was created, unifying clinical research infrastructure among the Departments of Critical Care Medicine, Emergency Medicine, and Surgery. During the periods 2008 to 2012, we performed a retrospective analysis and determined volume of clinical studies, patient enrollment for both observational and interventional trials, and staff growth since MACRO's origination and characterized changes over time. From 2008 to 2011, the volume of patients enrolled in clinical studies, which MACRO facilitates has significantly increased more than 300%. The percentage of interventional/observational trials has remained stable during the same period (50-60%). Staff has increased from 6 coordinators to 10, with an additional 15 research associates allowing 24/7 service. With this significant growth, MACRO has become financially self-sufficient, and additional outside departments now seek MACRO's services. Appropriate organization of acute care clinical research infrastructure minimizes redundancy and can promote sustainable, efficient growth in the current academic environment. Further studies are required to determine if similar models can be successful at other acute care surgery programs.

2016-01-01

Introduction: Since the European population is ageing, a growing number of elderly will need home care. Consequently, high quality home care for the elderly remains an important challenge. Job satisfaction among care professionals is regarded as an important aspect of the quality of home care. Aim: This paper describes a research protocol to identify elements that have an impact on job satisfaction among care professionals and on quality of care for older people in the home care setting of six European countries. Methods: Data on elements at the macro-level (policy), meso-level (care organisations) and micro-level (clients) are of importance in determining job satisfaction and quality of care. Macro-level indicators will be identified in a previously published literature review. At meso- and micro-level, data will be collected by means of two questionnaires utilsed with both care organisations and care professionals, and by means of interRAI Home Care assessments of clients. The client assessments will be used to calculate quality of care indicators. Subsequently, data will be analysed by means of linear and stepwise multiple regression analyses, correlations and multilevel techniques. Conclusions and Discussion: These results can guide health care policy makers in their decision making process in order to increase the quality of home care in their organisation, in their country or in Europe.

An new MHD/kinetic model for exploring energetic particle production in macro-scale systems

2017-12-01

A novel MHD/kinetic model is being developed to explore magneticreconnection and particle energization in macro-scale systems such asthe solar corona and the outer heliosphere. The model blends the MHDdescription with a macro-particle description. The rationale for thismodel is based on the recent discovery that energetic particleproduction during magnetic reconnection is controlled by Fermireflection and Betatron acceleration and not parallel electricfields. Since the former mechanisms are not dependent on kineticscales such as the Debye length and the electron and ion inertialscales, a model that sheds these scales is sufficient for describingparticle acceleration in macro-systems. Our MHD/kinetic model includesmacroparticles laid out on an MHD grid that are evolved with the MHDfields. Crucially, the feedback of the energetic component on the MHDfluid is included in the dynamics. Thus, energy of the total system,the MHD fluid plus the energetic component, is conserved. The systemhas no kinetic scales and therefore can be implemented to modelenergetic particle production in macro-systems with none of theconstraints associated with a PIC model. Tests of the new model insimple geometries will be presented and potential applications will bediscussed.

To identify contextual factors at different organisational levels to guide the implementation of an assistive living technology intervention in Norwegian primary home care. A single embedded case study design was carried out in an urban municipality in Western Norway to get an overview of key contextual factors from the municipality's perspective. The data collection was based on a triangulation of methods involving document analysis, semi-structured individual interviews and focus group interviews to get a broad insight when preparing for an intervention. Data were collected on three levels of the healthcare system: (1) national policy documents and regulations (macro), (2) five individual interviews with senior managers and municipal strategy documents (meso) and (3) two focus group interviews with nurses and nurse managers in direct patient care (micro). The Model for Understanding Success in Quality framework was used as a guide in the data analysis. The main contextual factors identified were external motivators and project sponsorship (macro level); leadership, workforce focus and maturity (meso level);and motivation to change and maturity (micro level). Strategies developed in policy documents affected upper management in the municipality, but healthcare personnel at the micro level were not so familiar with strategies and emphasis on assistive living technologies. Healthcare personnel in our study were motivated to use technological solutions, but lack of data infrastructure and resource availability hindered this. Aligning interests across multiple stakeholders remain a challenge when planning for an assistive living technology intervention in primary care. In the studied municipality, integration of technological solutions into healthcare services was more a vision than a reality because of a low level of organisational readiness. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Exploring domestic partnership benefits policies in corporate America.

Davidson, Elizabeth L; Rouse, Joy

2004-01-01

This article examines the domestic partner benefits (DP benefits) movement in corporate America, among Fortune 500 companies. An unprecedented number of Fortune 500 corporations started to extend equal benefits to their employees in the late 1990s. One-third of Fortune 500 companies now extend DP benefits to their gay employees despite national refusal to legally recognize same-sex unions. We provide a macro analysis of the 2002 Fortune 500 companies to explore the characteristics of the corporations that offer the benefits and the impetus for adopting these new gay friendly policies. Findings are that top ranked Fortune 500 and industry leaders act as benchmarkers for the corporate community. Region of the corporate headquarters and commitment to diversity issues also inform these organizational changes. Isomorphisic processes offer viable explanations for the transformation of the corporate climate that touts DP benefit policies as "the right thing to do" and considers these policies as good business sense in order to compete for employees. The DP benefits movement reflects corporate America trying to enhance their reputational capital by including gay issues as part of their diversity programs and policies.

Welfare regimes, labour policies and unhealthy psychosocial working conditions: a comparative study with 9917 older employees from 12 European countries.

Dragano, Nico; Siegrist, Johannes; Wahrendorf, Morten

2011-09-01

Recent analyses explored associations of welfare state regimes with population health, with particular interest in differences between social protection-oriented versus more liberal regimes. Little is known about such associations with work-related health. The aims of this contribution are (1) to study variations of quality of work according to type of welfare regime and (2) to analyse differences in the size of effects of quality of work on workers' health according to type of welfare regime. The authors use cross-sectional and longitudinal data from two studies ('Survey of Health, Ageing and Retirement in Europe' and the 'English Longitudinal Study on Ageing') with 9917 employed men and women (aged 50 to 64) in 12 European countries. Psychosocial quality of work is measured by low control and effort-reward imbalance at work. Depressive symptoms are introduced as a health indicator. Linear multilevel models and logistic regression analyses are performed to test the hypotheses. In addition to the welfare regime typology, the authors introduce labour policy and economy-related macro indicators. Between-country variations in quality of work are largely explained by macro indicators and welfare regimes, with poorer quality of work in countries with less emphasis on older workers' protection. Moreover, in the Liberal and Southern welfare regime, effects of quality of work on depressive symptoms are relatively strongest (adjusted ORs varying from 1.45 to 2.64). Active labour policies and reliable social protection measures (eg, Scandinavian welfare regime) exert beneficial effects on the health and well-being of older workers. More emphasis on improving quality of work among this group is warranted.

Ontario's Poverty Reduction Strategy: A Critical Discourse Analysis.

2016-01-01

This article overviews the second phase of a two-phase study which examined experiences of health and social exclusion among mothers experiencing homelessness in Ontario, Canada. A critical discourse analysis was employed to analyze the policy document, Realizing Our Potential: Ontario's Poverty Reduction Strategy, 2014-2019. In nursing, analysis of policy is an emerging form of scholarship, one that draws attention to the macro levels influencing health and health promotion, such as the social determinants of health, and the policies that impact them. The clear neo-liberal underpinnings, within the strategy, with a focus on productivity and labor market participation leave little room for an understanding of poverty reduction from a human rights perspective. Further, gender-neutrality rendered the poverty experienced by women, and mothers, invisible. Notably, there were a lack of deadlines, target dates, and thorough action and evaluation plans. Such absence troubles whether poverty reduction is truly a priority for the government, and society as a whole.

Political democracy, economic liberalization, and macro-sociological models of intergenerational mobility.

PubMed

Gugushvili, Alexi

2017-08-01

Building on the previously investigated macro-sociological models which analyze the consequences of economic development, income inequality, and international migration on social mobility, this article studies the specific contextual covariates of intergenerational reproduction of occupational status in post-communist societies. It is theorized that social mobility is higher in societies with democratic political regimes and less liberalized economies. The outlined hypotheses are tested by using micro- and macro-level datasets for 21 post-communist societies which are fitted into multilevel mixed-effects linear regressions. The derived findings suggest that factors specific to transition societies, conventional macro-level variables, and the legacy of the Soviet Union explain variation in intergenerational social mobility, but the results vary depending which birth cohorts survey participants belong to and whether or not they stem from advantaged or disadvantaged social origins. These findings are robust to various alternative data, sample, and method specifications. Copyright © 2017 Elsevier Inc. All rights reserved.

Macro-/Micro-Controlled 3D Lithium-Ion Batteries via Additive Manufacturing and Electric Field Processing.

Li, Jie; Liang, Xinhua; Liou, Frank; Park, Jonghyun

2018-01-30

This paper presents a new concept for making battery electrodes that can simultaneously control macro-/micro-structures and help address current energy storage technology gaps and future energy storage requirements. Modern batteries are fabricated in the form of laminated structures that are composed of randomly mixed constituent materials. This randomness in conventional methods can provide a possibility of developing new breakthrough processing techniques to build well-organized structures that can improve battery performance. In the proposed processing, an electric field (EF) controls the microstructures of manganese-based electrodes, while additive manufacturing controls macro-3D structures and the integration of both scales. The synergistic control of micro-/macro-structures is a novel concept in energy material processing that has considerable potential for providing unprecedented control of electrode structures, thereby enhancing performance. Electrochemical tests have shown that these new electrodes exhibit superior performance in their specific capacity, areal capacity, and life cycle.

Critique of Macro Flow/Damage Surface Representations for Metal Matrix Composites Using Micromechanics

NASA Technical Reports Server (NTRS)

Lissenden, Cliff J.; Arnold, Steven M.

1996-01-01

Guidance for the formulation of robust, multiaxial, constitutive models for advanced materials is provided by addressing theoretical and experimental issues using micromechanics. The multiaxial response of metal matrix composites, depicted in terms of macro flow/damage surfaces, is predicted at room and elevated temperatures using an analytical micromechanical model that includes viscoplastic matrix response as well as fiber-matrix debonding. Macro flow/damage surfaces (i.e., debonding envelopes, matrix threshold surfaces, macro 'yield' surfaces, surfaces of constant inelastic strain rate, and surfaces of constant dissipation rate) are determined for silicon carbide/titanium in three stress spaces. Residual stresses are shown to offset the centers of the flow/damage surfaces from the origin and their shape is significantly altered by debonding. The results indicate which type of flow/damage surfaces should be characterized and what loadings applied to provide the most meaningful experimental data for guiding theoretical model development and verification.

SNMG: a social-level norm-based methodology for macro-governing service collaboration processes

Gao, Ji; Lv, Hexin; Jin, Zhiyong; Xu, Ping

2017-08-01

In order to adapt to the accelerative open tendency of collaborations between enterprises, this paper proposes a Social-level Norm-based methodology for Macro-Governing service collaboration processes, called SNMG, to regulate and control the social-level visible macro-behaviors of the social individuals participating in collaborations. SNMG not only can remove effectively the uncontrollability hindrance confronted with by open social activities, but also enables across-management-domain collaborations to be implemented by uniting the centralized controls of social individuals for respective social activities. Therefore, this paper provides a brand-new system construction mode to promote the development and large-scale deployment of service collaborations.

Coping with seismic vulnerability: small manufacturing firms in western Athens.

PubMed

Sapountzaki, Kalliopi

2005-06-01

This paper attempts to contribute to international discourse on the responsibility of macro structures (economic and political) and private agencies for the production and distribution of vulnerability. It does so by focusing on an individual economic entity, small manufacturing firms (SMFs), in a specific location, western Athens, Greece. By evaluating the losses that SMFs sustained in the earthquake of 7 September 1999, the paper points to variations in vulnerability levels among such firms and highlights the 'sources' of vulnerability they confront. Furthermore, the SMF recovery cycle is systematically monitored in parallel with relevant public policies and state reactions to private recovery methods. The analysis illustrates processes that externalise recovery costs, alter the relationship between physical and socio-economic vulnerability and shift the vulnerability load from macro structures to individual agencies or vice versa. It is based on two methodological approaches: the division of vulnerability into three constituent components (exposure, resistance and resilience); and the conceptual split between producers and carriers of vulnerability.

2010-12-01

Model-based analyses built on burden-of-disease and cost-effectiveness theory predict that pharmaceutical interventions may efficiently mitigate both the epidemiologic and economic impact of an influenza pandemic. Pharmaceutical interventions typically encompass the application of (pre)pandemic influenza vaccines, other vaccines (notably pneumococcal), antiviral treatments and other drug treatment (e.g., antibiotics to target potential complications of influenza). However, these models may be too limited to capture the full macro-economic impact of pandemic influenza. The aim of this article is to summarize current health-economic modeling approaches to recognize the strengths and weaknesses of these approaches, and to compare these with more recently proposed alternative methods. We conclude that it is useful, particularly for policy and planning purposes, to extend modeling concepts through the application of alternative approaches, including insurers' risk theories, human capital approaches and sectoral and full macro-economic modeling. This article builds on a roundtable meeting of the Pandemic Influenza Economic Impact Group that was held in Boston, MA, USA, in December 2008.

Symbolic interactionism and critical perspective: divergent or synergistic?

PubMed

Burbank, Patricia M; Martins, Diane C

2010-01-01

Throughout their history, symbolic interactionism and critical perspective have been viewed as divergent theoretical perspectives with different philosophical underpinnings. A review of their historical and philosophical origins reveals both points of divergence and areas of convergence. Their underlying philosophies of science and views of human freedom are different as is their level of focus with symbolic interactionism having a micro perspective and critical perspective using a macro perspective. This micro/macro difference is reflected in the divergence of their major concepts, goals and basic tenets. While their underlying philosophies are different, however, they are not necessarily contradictory and areas of convergence may include the concepts of reference groups and looking glass self within symbolic interactionism and ideological hegemony within critical perspective. By using a pragmatic approach and combining symbolic interactionism and critical perspectives, both micro and macro levels come into focus and strategies for change across individual and societal levels can be developed and applied. Application of both symbolic interactionism and critical perspective to nursing research and scholarship offers exciting new opportunities for theory development and research methodologies. In nursing education, these two perspectives can give students added insight into patients' and families' problems at the micro level while, at the same time, giving them a lens to see and tools to apply to problems at the macro level in health care. In nursing practice, a combined symbolic interactionism/critical perspective approach assists nurses to give high-quality care at the individual level while also working at the macro level to address the manufacturers of illness. New research questions emerge from this combination of perspectives with new possibilities for theory development, a transformation in nursing education, and the potential for new practice strategies that can address individual client and larger system problems through empowerment of clients and nurses.

Coronary artery disease remains a major cause of mortality in developed countries, and is most often due to a localized flow-limiting stenosis, or narrowing, of coronary arteries. Patients often undergo invasive procedures such as X-ray angiography and fractional flow reserve to diagnose flow-limiting lesions. Even though such diagnostic techniques are well-developed, the effects of diseased coronary segments on local flow are still poorly understood. Therefore, this study investigated the effect of irregular geometries of diseased coronary segments on the macro-recirculation and local pressure minimum regions. We employed an idealized coronary artery model with a diameter of stenosis of 75%. By systematically adjusting the eccentricity and the asymmetry of the coronary stenosis, we uncovered an increase in macro-recirculation size. Most importantly, the presence of this macro-recirculation signifies a local pressure minimum (identified by λ2 vortex identification method). This local pressure minimum has a profound effect on the pressure drops in both longitudinal and planar directions, which has implications for diagnosis and treatment of coronary artery disease.

Estimation of genetic variance for macro- and micro-environmental sensitivity using double hierarchical generalized linear models

PubMed Central

2013-01-01

Background Genetic variation for environmental sensitivity indicates that animals are genetically different in their response to environmental factors. Environmental factors are either identifiable (e.g. temperature) and called macro-environmental or unknown and called micro-environmental. The objectives of this study were to develop a statistical method to estimate genetic parameters for macro- and micro-environmental sensitivities simultaneously, to investigate bias and precision of resulting estimates of genetic parameters and to develop and evaluate use of Akaike’s information criterion using h-likelihood to select the best fitting model. Methods We assumed that genetic variation in macro- and micro-environmental sensitivities is expressed as genetic variance in the slope of a linear reaction norm and environmental variance, respectively. A reaction norm model to estimate genetic variance for macro-environmental sensitivity was combined with a structural model for residual variance to estimate genetic variance for micro-environmental sensitivity using a double hierarchical generalized linear model in ASReml. Akaike’s information criterion was constructed as model selection criterion using approximated h-likelihood. Populations of sires with large half-sib offspring groups were simulated to investigate bias and precision of estimated genetic parameters. Results Designs with 100 sires, each with at least 100 offspring, are required to have standard deviations of estimated variances lower than 50% of the true value. When the number of offspring increased, standard deviations of estimates across replicates decreased substantially, especially for genetic variances of macro- and micro-environmental sensitivities. Standard deviations of estimated genetic correlations across replicates were quite large (between 0.1 and 0.4), especially when sires had few offspring. Practically, no bias was observed for estimates of any of the parameters. Using Akaike’s information criterion the true genetic model was selected as the best statistical model in at least 90% of 100 replicates when the number of offspring per sire was 100. Application of the model to lactation milk yield in dairy cattle showed that genetic variance for micro- and macro-environmental sensitivities existed. Conclusion The algorithm and model selection criterion presented here can contribute to better understand genetic control of macro- and micro-environmental sensitivities. Designs or datasets should have at least 100 sires each with 100 offspring. PMID:23827014

There were some think tank businesses in Japan before the war. South Manchuria Railway Company established its Research Department for the purpose of getting power to control Manchuria as a colony, and got the good results. Think tank business was flourishing three times after the war. This business attracts much attention when the social and economic paradigm is going to change. Among the key large-scale think tanks in Japan, Nomura Research Institute, Ltd. (NRI) was the first to enhance the system functions by the merger, and posted think tank function up in the SI business. Mitsubishi Research Institute, Inc. (MRI) intends to be an orthodox think tank, and established an advanced research institute and the laboratory for R&D. Daiwa Institute of Research, Ltd. (DIR) focuses on economic forecast by using system. Fuji Research Institute. Corp. (FUJI RIC) focuses on survey and policy proposing in macro-economics, and analyzing technology. The Japan Research Institute, Ltd. (JRI) focuses on regional development, and R&D in advanced technology.

The monitoring of genetically modified organisms (GMOs) is a primary step of GMO regulation. However, there is presently a lack of effective and high-throughput methodologies for specifically and sensitively monitoring most of the commercialized GMOs. Herein, we developed a multiplex amplification on a chip with readout on an oligo microarray (MACRO) system specifically for convenient GMO monitoring. This system is composed of a microchip for multiplex amplification and an oligo microarray for the readout of multiple amplicons, containing a total of 91 targets (18 universal elements, 20 exogenous genes, 45 events, and 8 endogenous reference genes) that covers 97.1% of all GM events that have been commercialized up to 2012. We demonstrate that the specificity of MACRO is ~100%, with a limit of detection (LOD) that is suitable for real-world applications. Moreover, the results obtained of simulated complex samples and blind samples with MACRO were 100% consistent with expectations and the results of independently performed real-time PCRs, respectively. Thus, we believe MACRO is the first system that can be applied for effectively monitoring the majority of the commercialized GMOs in a single test.

We use newly developed methods of measuring spatial segregation across a range of spatial scales to assess changes in racial residential segregation patterns in the 100 largest U.S. metropolitan areas from 1990 to 2000. Our results point to three notable trends in segregation from 1990 to 2000: 1) Hispanic-white and Asian-white segregation levels increased at both micro- and macro-scales; 2) black-white segregation declined at a micro-scale, but was unchanged at a macro-scale; and 3) for all three racial groups and for almost all metropolitan areas, macro-scale segregation accounted for more of the total metropolitan area segregation in 2000 than in 1990. Our examination of the variation in these trends among the metropolitan areas suggests that Hispanic-white and Asian-white segregation changes have been driven largely by increases in macro-scale segregation resulting from the rapid growth of the Hispanic and Asian populations in central cities. The changes in black-white segregation, in contrast, appear to be driven by the continuation of a 30-year trend in declining micro-segregation, coupled with persistent and largely stable patterns of macro-segregation.

Causality in cancer research: a journey through models in molecular epidemiology and their philosophical interpretation.

PubMed

Vineis, Paolo; Illari, Phyllis; Russo, Federica

2017-01-01

In the last decades, Systems Biology (including cancer research) has been driven by technology, statistical modelling and bioinformatics. In this paper we try to bring biological and philosophical thinking back. We thus aim at making different traditions of thought compatible: (a) causality in epidemiology and in philosophical theorizing-notably, the "sufficient-component-cause framework" and the "mark transmission" approach; (b) new acquisitions about disease pathogenesis, e.g. the "branched model" in cancer, and the role of biomarkers in this process; (c) the burgeoning of omics research, with a large number of "signals" and of associations that need to be interpreted. In the paper we summarize first the current views on carcinogenesis, and then explore the relevance of current philosophical interpretations of "cancer causes". We try to offer a unifying framework to incorporate biomarkers and omic data into causal models, referring to a position called "evidential pluralism". According to this view, causal reasoning is based on both "evidence of difference-making" (e.g. associations) and on "evidence of underlying biological mechanisms". We conceptualize the way scientists detect and trace signals in terms of information transmission , which is a generalization of the mark transmission theory developed by philosopher Wesley Salmon. Our approach is capable of helping us conceptualize how heterogeneous factors such as micro and macro-biological and psycho-social-are causally linked. This is important not only to understand cancer etiology, but also to design public health policies that target the right causal factors at the macro-level.

The Indonesian economic indicators shown a positive progress in the last three years, Foreign exchange reserves position of the end of March 2017 stood at US 121.8 billion higher than the position of the end of 2015 amounted to US 105.9 billion of the end of 2015. This reserve would ensure the resilience and maintaining sustainable Indonesian economic growth in the future. Although Indonesia’s foreign exchange is better, the structure of expenditure in the country is still less than ideal due the proportion of spending of consumer goods is far greater than the capital goods and tend to be unproductive spending. This needs to be regulated so that in the long term does not cause balance of payments deficit. Therefore, Indonesian Central Bank took a policy to raise interest rates for retail banks from 6% to 7.25% per annum gradually up to present. Policies relating to the interest rates on loans are intended to reduce the proportion of debt financing of consumer goods, however, these policies have implications to various economic sectors and one of those is property sector. A lot of research has been conducted related the impact of loan interest to the property sector but most of it is still in partial related to the ability the people to buy. However, this research has tried to see the implication of the macro Economic Policy of Indonesian Central Bank to the property sector as a systemic problem. This paper is going to present the study on the effects of these policies on the property sector, especially residence house. To obtain a comprehensive analysis and capture the relationship between interest rate policies and their impacts to the property sector, in this study the model developed and simulated using system dynamic methodology as an approach. Various scenarios are applied to the model to get an accurate information about how and when the effectiveness of the policy related to the property sector can be enforced. The result of this study can be delivered to the policy maker as feed-back to improving the policies related the interest rate.

Virtual reality as a human factors design analysis tool: Macro-ergonomic application validation and assessment of the Space Station Freedom payload control area

NASA Technical Reports Server (NTRS)

Hale, Joseph P.

1994-01-01

A virtual reality (VR) Applications Program has been under development at MSFC since 1989. Its objectives are to develop, assess, validate, and utilize VR in hardware development, operations development and support, missions operations training, and science training. A variety of activities are under way within many of these areas. One ongoing macro-ergonomic application of VR relates to the design of the Space Station Freedom Payload Control Area (PCA), the control room from which onboard payload operations are managed. Several preliminary conceptual PCA layouts have been developed and modeled in VR. Various managers and potential end users have virtually 'entered' these rooms and provided valuable feedback. Before VR can be used with confidence in a particular application, it must be validated, or calibrated, for that class of applications. Two associated validation studies for macro-ergonomic applications are under way to help characterize possible distortions of filtering of relevant perceptions in a virtual world. In both studies, existing control rooms and their 'virtual counterparts will be empirically compared using distance and heading estimations to objects and subjective assessments. Approaches and findings of the PCA activities and details of the studies are presented.

Thermo-Oxidative Induced Damage in Polymer Composites: Microstructure Image-Based Multi-Scale Modeling and Experimental Validation

Hussein, Rafid M.; Chandrashekhara, K.

2017-11-01

A multi-scale modeling approach is presented to simulate and validate thermo-oxidation shrinkage and cracking damage of a high temperature polymer composite. The multi-scale approach investigates coupled transient diffusion-reaction and static structural at macro- to micro-scale. The micro-scale shrinkage deformation and cracking damage are simulated and validated using 2D and 3D simulations. Localized shrinkage displacement boundary conditions for the micro-scale simulations are determined from the respective meso- and macro-scale simulations, conducted for a cross-ply laminate. The meso-scale geometrical domain and the micro-scale geometry and mesh are developed using the object oriented finite element (OOF). The macro-scale shrinkage and weight loss are measured using unidirectional coupons and used to build the macro-shrinkage model. The cross-ply coupons are used to validate the macro-shrinkage model by the shrinkage profiles acquired using scanning electron images at the cracked surface. The macro-shrinkage model deformation shows a discrepancy when the micro-scale image-based cracking is computed. The local maximum shrinkage strain is assumed to be 13 times the maximum macro-shrinkage strain of 2.5 × 10-5, upon which the discrepancy is minimized. The microcrack damage of the composite is modeled using a static elastic analysis with extended finite element and cohesive surfaces by considering the modulus spatial evolution. The 3D shrinkage displacements are fed to the model using node-wise boundary/domain conditions of the respective oxidized region. Microcrack simulation results: length, meander, and opening are closely matched to the crack in the area of interest for the scanning electron images.

Perception of recovery of households affected by 2008 Wenchuan earthquake: A structural equation model

Lin, Le; Wang, Ying; Liu, Tianxue

2017-01-01

Much of the literature on recovery focuses on the economy, the physical environment and infrastructure at a macro level, which may ignore the personal experiences of affected individuals during recovery. This paper combines internal factors at a micro level and external factors at a macro level to model for understanding perception of recovery (PoR). This study focuses on areas devastated by the 2008 Wenchuan earthquake in China. With respect to three recovery-related aspects (house recovery condition (HRC), family recovery power (FRP) and reconstruction investment (RI)), structural equation modeling (SEM) was applied. It was found that the three aspects (FRP, HRC and RI) effectively explain how earthquake affected households perceive recovery. Internal factors associated with FRP contributed the most to favourable PoR, followed by external factors associated with HRC. Findings identified that for PoR the importance of active recovery within households outweighed an advantageous house recovery condition. At the same time, households trapped in unfavourable external conditions would invest more in housing recovery, which result in wealth accumulation and improved quality of life leading to a high level of PoR. In addition, schooling in households showed a negative effect on improving PoR. This research contributes to current debates around post-disaster permanent housing policy. It is implied that a one-size-fits-all policy in disaster recovery may not be effective and more specific assistance should be provided to those people in need. PMID:28854217

California aims to reduce greenhouse gas (GHG) emissions to 40% below 1990 levels by 2030. We compare six energy models that have played various roles in informing the state policymakers in setting climate policy goals and targets. These models adopt a range of modeling structures, including stock-turnover back-casting models, a least-cost optimization model, macroeconomic/macro-econometric models, and an electricity dispatch model. Results from these models provide useful insights in terms of the transformations in the energy system required, including efficiency improvements in cars, trucks, and buildings, electrification of end-uses, low- or zero-carbon electricity and fuels, aggressive adoptions of zero-emission vehicles (ZEVs),more » demand reduction, and large reductions of non-energy GHG emissions. Some of these studies also suggest that the direct economic costs can be fairly modest or even generate net savings, while the indirect macroeconomic benefits are large, as shifts in employment and capital investments could have higher economic returns than conventional energy expenditures. These models, however, often assume perfect markets, perfect competition, and zero transaction costs. They also do not provide specific policy guidance on how these transformative changes can be achieved. Greater emphasis on modeling uncertainty, consumer behaviors, heterogeneity of impacts, and spatial modeling would further enhance policymakers' ability to design more effective and targeted policies. Here, this paper presents an example of how policymakers, energy system modelers and stakeholders interact and work together to develop and evaluate long-term state climate policy targets. Lastly, even though this paper focuses on California, the process of dialogue and interactions, modeling results, and lessons learned can be generally adopted across different regions and scales.« less

Globalisation and women in India.

PubMed

Krishnaraj, M

1999-11-01

Globalization arrived in India through an external and internal alignment of political and economic forces that led to the opening of the country to the outside world. The five processes under globalization are: 1) commercialism wherein more services become monetized and incomes are received in money rather than in kind; 2) more capitalization; 3) foreign trade becomes important for the production and distribution process; 4) greater financialization develops; and 5) international capital moves freely. These changes affect women more than men in different ways. Capitalization results in more self-employed marginal farmers becoming wage workers, making it less possible for women to manage domestic duties alongside their productive work. In general, macro-economic policies affect women through the household, market, and gender relations. In countries like India where women suffer from serious discrimination, whatever affects the household will worsen women's position. Thus, the process of liberalization, privatization, and globalization will put the clock back for women and for the poor in general.

Macro-SICM: A Scanning Ion Conductance Microscope for Large-Range Imaging.

2018-04-17

The scanning ion conductance microscope (SICM) is a versatile, high-resolution imaging technique that uses an electrolyte-filled nanopipet as a probe. Its noncontact imaging principle makes the SICM uniquely suited for the investigation of soft and delicate surface structures in a liquid environment. The SICM has found an ever-increasing number of applications in chemistry, physics, and biology. However, a drawback of conventional SICMs is their relatively small scan range (typically 100 μm × 100 μm in the lateral and 10 μm in the vertical direction). We have developed a Macro-SICM with an exceedingly large scan range of 25 mm × 25 mm in the lateral and 0.25 mm in the vertical direction. We demonstrate the high versatility of the Macro-SICM by imaging at different length scales: from centimeters (fingerprint, coin) to millimeters (bovine tongue tissue, insect wing) to micrometers (cellular extensions). We applied the Macro-SICM to the study of collective cell migration in epithelial wound healing.

Obesity and climate change mitigation in Australia: overview and analysis of policies with co-benefits.

2014-02-01

To provide an overview of the shared structural causes of obesity and climate change, and analyse policies that could be implemented in Australia to both equitably reduce obesity rates and contribute to mitigating climate change. Informed by the political economy of health theoretical framework, a review was conducted of the literature on the shared causes of, and solutions to, obesity and climate change. Policies with potential co-benefits for climate change and obesity were then analysed based upon their feasibility and capacity to reduce greenhouse gas emissions and equitably reduce obesity rates in Australia. Policies with potential co-benefits fit within three broad categories: those to replace car use with low-emissions, active modes of transport; those to improve diets and reduce emissions from the food system; and macro-level economic policies to reduce the over-consumption of food and fossil fuel energy. Given the complex causes of both problems, it is argued that a full spectrum of complementary strategies across different sectors should be utilised. Such an approach would have significant public health, social and environmental benefits. © 2014 The Authors. ANZJPH © 2014 Public Health Association of Australia.

The rapid reproducers paradox: population control and individual procreative rights.

PubMed

Wissenburg, M

1998-01-01

This article argues that population policies need to be evaluated from macro and micro perspectives and to consider individual rights. Ecological arguments that are stringent conditions of liberal democracy are assessed against a moral standard. The moral standard is applied to a series of reasons for limiting procreative rights in the cause of sustainability. The focus is directly on legally enforced antinatalist measures and not on indirect policies with incentives and disincentives. The explicit assumption is that population policy violates the fairness to individuals for societal gain and that population policies are incompatible with stringent conditions of liberal democracy. The author identifies the individual-societal tradeoff as the "rapid reproducers paradox." The perfect sustainable population level is either not possible or is a repugnant alternative. 12 ecological arguments are presented, and none are found compatible with notions of a liberal democracy. Three alternative antinatalist options are the acceptance of less rigid and still coercive policies, amendments to the conception of liberal democracy, or loss of hope and choice of noncoercive solutions to sustainability, none of which is found viable. If voluntary abstinence and distributive solutions fail, then frugal demand options and technological supply options both will be necessary.

The relevance and importance of research for understanding policy processes and influencing policies has been much debated, but studies on the effectiveness of policy theories for predicting and informing opportunities for policy change (i.e. prospective policy analysis) are rare. The case study presented in this paper is drawn from a policy analysis of a contemporary process of policy debate on legalization of abortion in Indonesia, which was in flux at the time of the research and provided a unique opportunity for prospective analysis. Applying a combination of policy analysis theories, this case study provides an analysis of processes, power and relationships between actors involved in the amendment of the Health Law in Indonesia. It uses a series of practical stakeholder mapping tools to identify power relations between key actors and what strategic approaches should be employed to manage these to enhance the possibility of policy change. The findings show how the moves to legalize abortion have been supported or constrained according to the balance of political and religious powers operating in a macro-political context defined increasingly by a polarized Islamic-authoritarian—Western-liberal agenda. The issue of reproductive health constituted a battlefield where these two ideologies met and the debate on the current health law amendment became a contest, which still continues, for the larger future of Indonesia. The findings confirm the utility of policy analysis theories and stakeholder mapping tools for predicting the likelihood of policy change and informing the strategic approaches for achieving such change. They also highlight opportunities and dilemmas in prospective policy analysis and raise questions about whether research on policy processes and actors can or should be used to inform, or even influence, policies in ‘real-time’.

Development, health, and international policy: the research and innovation dimension.

Buss, Paulo Marchiori; Chamas, Claudia; Faid, Miriam; Morel, Carlos

2016-11-03

This text main objective is to discuss development and health from the perspective of the influence of global health governance, using as the tracer the dimension of research, development, and innovation policies in health, which relate to both important inputs for the health system, like drugs and medicines, vaccines, diagnostic reagents, and equipment, and innovative concepts and practices for the improvement of health systems and public health. The authors examine the two main macro-processes that influence development and health: the post-2015 Development Agenda and the process under way in the World Health Organization concerning research and development, intellectual property, and access to health inputs. The article concludes, first, that much remains to be done for the Agenda to truly represent a coherent and viable international political pact, and that the two macro-processes related to innovation in health need to be streamlined. But this requires democratization of participation by the main stakeholders - patients and the general population of the poorest countries - since this is the only way to overcome a "zero sum" result in the clash in the current debates among member State representatives. Resumo: O objetivo central deste texto é discutir desenvolvimento e saúde sob a ótica da influência da governança da saúde global, utilizando como traçador a dimensão das políticas de pesquisa, desenvolvimento e inovação em saúde, que se referem, de um lado, a insumos importantes para o sistema de saúde - como fármacos e medicamentos, vacinas, reativos para diagnóstico e equipamentos e, de outro, a conceitos e práticas inovadoras para o aperfeiçoamento dos sistemas de saúde e da saúde pública. Examina os dois principais macroprocessos que influenciam o desenvolvimento e a saúde: a Agenda do Desenvolvimento para o pós-2015 e o processo sobre pesquisa e desenvolvimento, propriedade intelectual e acesso a insumos em saúde em curso na Organização Mundial da Saúde. Conclui que muito há que ser feito para que a referida Agenda possa representar um pacto político internacional coerente e viável, e que os dois macroprocessos relacionados com a inovação em saúde precisam ser agilizados, mas para isto torna-se necessária a democratização da participação dos maiores interessados - os pacientes e, de modo geral, a população dos países mais pobres - pois só desta maneira será superada a "soma zero" em que se encontra o embate entre os representantes de Estados-membros nos debates atuais.

Managing Nitrogen in the anthropocene: integrating social and ecological science

Human alteration of the global nitrogen cycle by agricultural activities has provided nutritious food to society, but also poses increasing threats to human and ecosystem health through unintended pollution. Managing nitrogen more efficiently in crop production is critical for addressing both food security and environmental challenges. Technologies and management practices have been developed to increase the uptake of applied nitrogen by crops. However, nitrogen use efficiency (NUE, yield per unit nitrogen input) is also affected by social and economic factors. For example, to maximize profit, farmers may change crop choice or their nitrogen application rate, both of which lead to a change in NUE. To evaluate such impacts, we use both theoretical and empirical approaches on micro (farm) and macro (national) scales: 1) We developed a bio-economic model (NUE3) on a farm scale to investigate how market signals (e.g. fertilizer and crop prices), government policies, and nitrogen-efficient technologies affect NUE. We demonstrate that if factors that influence nitrogen inputs (e.g. fertilizer-to-crop price ratios) are not considered, NUE projections will be poorly constrained. The impact of nitrogen-efficient technologies on NUE not only depends on how technology changes the production function, but also relies on the prices of the technologies, fertilizers, and crops. 2) We constructed a database of the nitrogen budget in crop production for major crops and major crop producing countries from 1961 to 2010. Using this database, we investigate historical trends of NUE and its relationship to agronomic, economic, social, and policy factors. We find that NUE in most developed countries follows a "U-shape" relationship with income level, consistent with the Environmental Kuznets Curve theory. According to the dynamics revealed in the NUE3 model, we propose three major pathways by which economic development affects NUE, namely consumption, technology, and public policy. Overall, our research suggests that it is critical to include social and economic processes when studying perturbations of the global nitrogen cycle and crafting environmental and food security policy. Better collaboration across disciplines is essential to improve nitrogen management in the anthropocene.

The macro-micro combined approach, as an effective way to realize trans-scale nano-precision positioning with multi-dimensions and high velocity, plays a significant role in integrated circuit manufacturing field. A 3-degree-of-freedoms (3-DOFs) macro-micro manipulator is designed and analyzed to compromise the conflictions among the large stroke, high precision and multi-DOFs. The macro manipulator is a 3-Prismatic-Revolute-Revolute (3-PRR) structure parallel manipulator which is driven by three linear ultrasonic motors. The dynamic model and the cross-coupling error based synchronized motion controller of the 3-PRR parallel manipulator are theoretical analyzed and experimental tested. To further improve the positioning accuracy, a 3-DOFs monolithic compliant manipulator actuated by three piezoelectric stack actuators is designed. Then a multilayer BP neural network based inverse kinematic model identifier is developed to perform the positioning control. Finally, by forming the macro-micro structure, the dual stage manipulator successfully achieved the positioning task from the point (2 mm, 2 mm, 0 rad) back to the original point (0 mm, 0 mm, 0 rad) with the translation errors in X and Y directions less than ±50 nm and the rotation error around Z axis less than ±1 μrad, respectively.

Towards balanced development in Pakistan.

Pyatt, G

1992-01-01

Pakistan is a country whose economic growth is surprising in light of its social indicators. The aim of this article is to examine why conditions are such and to develop a framework for understanding the issues as an aid to redesigning policies. 5 sections are devoted to a summary of the main findings, the diagnosis of development and the impact on social sectors, a proposal for balanced development, and implications for policy changes. A sound macro economic context is needed with reforms economically in price and incentive systems, institutionally, and in the law and order sector. Public administration needs to be improved and individual opportunities need to be expanded. Internal security needs to be secured, so that law and order are restored. Economic growth has been high between 1960 and 1988, due to exploitation of natural resources and cheap unskilled labor, expansion of irrigated land, and growth of the unregulated informal sector. The major constraints on economic growth will come from a lack of fiscal discipline. 40% of government revenues are consumed by the military and 20% for servicing debt. Other constraints are the population growth rate in excess of 3%/year, an urban bias in allocation of resources, neglected primary education, and gender bias in education. There has been little incentive for provincial governments to balance budgets, and civil service has become disorganized. Balanced development entails recognizing human capital, natural resources, and infrastructure; accepting the status quo; and creating and maintaining an institutional framework to correct market failures and promote individual opportunities. The environmental polluter must pay. Income must be increased through higher wages, increasing the demand for labor, and transfers to households in the form of food rations, schooling, and medical care. Investment in women will increase household earnings, and improve living conditions and the health of themselves and their children. Balanced development must alleviate poverty. Policies can be evaluated in terms of access, delivery, training, and financing; discussion follows on the failings of and needs for family planning, health, and education, and the implications for institutional policy. Balanced development as optimum use of existing resources and investment in areas with the highest return is movement in the right direction, assumes equality of opportunity, but does not provide social security.

Moving beyond normative philosophies and policy concerns: a sociological account of place-based solidarities in diversity.

PubMed

Oosterlynck, Stijn

2018-01-01

In this commentary, I think with and beyond the normative philosophies and policy-oriented frameworks on how to deal with diversity in contemporary societies formulated by Zapata-Barrero and Modood. I propose to integrate elements of both perspectives in a empirically grounded sociological account of how place-based solidarities in diversity are nurtured in everyday life. Although there is much to be recommended about the arguments of Modood and Zapata-Barrero, I argue that what is needed is an analytical framework that does not a priori privilege specific sources of solidarity on normative-philosophical or policy grounds. We need to focus instead on how people mobilise different sources of solidarity in their attempts to take shared responsibility for the concrete places where they live, work, learn and play together in superdiversity. This micro-level focus does not mean that one ignores macro-level processes. Also, more attention should be paid to the transformative nature of solidarities in diversity.

At their 2009 consensus conference, the International CBME Collaborators proposed a number of central tenets of CBME in order to advance the field of medical education. Although the proposed conceptualization of CBME offers several advantages and opportunities, including a greater emphasis on outcomes, a mechanism for the promotion of learner-centred curricula, and the potential to move away from time-based training and credentialing in medicine, it is also associated with several significant barriers to adoption. This paper examines the concepts of CBME through a broad educational policy lens, identifying considerations for medical education leaders, health care institutions, and policy-makers at both the meso (program, institutional) and macro (health care system, inter-jurisdictional, and international) levels. Through this analysis, it is clear that CBME is associated with a number of complex challenges and questions, and cannot be considered in isolation from the complex systems in which it functions. Much more work is needed to engage stakeholders in dialogue, to debate the issues, and to identify possible solutions.

This study aims to compare Primary Health Care (PHC) in Brazil and Venezuela, considering its characteristics as to integrality. It has a qualitative approach, using documental analysis, semi-structured interviews with key informants and field diary notes. We observed the three realms of integrality inherent to the health work process: comprehensive and holistic care, the individual viewed as a complex being with multiple needs, requiring the connection of various health knowledge; continuity of care in institutional micro-policy with interprofessional articulation, in order to consider individual care; continuity of care in macro-policy, when a shift to other levels of care is needed; intersectoriality was also included, when the needs of an individual and community require a cross-sectoral coordination, with action on determinants and conditionants of the health-disease process. It is worth highlighting the natural tendency to include a comprehensive community medical training. We conclude that those countries strengthened by democracy draw their integrality practices closer, as well as the construction of social and health policies for underprivileged populations to achieve equity.

Background: Communicable Disease Surveillance and reporting is one of the key elements to combat against diseases and their control. Fast and timely recognition of communicable diseases can be helpful in controlling of epidemics. One of the main sources of management of communicable diseases reporting is hospitals that collect communicable diseases’ reports and send them to health authorities. One of the focal problems and challenges in this regard is incomplete and imprecise reports from hospitals. In this study, while examining the implementation processes of the communicable diseases surveillance in hospitals, non-medical people who were related to the program have been studied by a qualitative approach. Methods: This study was conducted using qualitative content analysis method. Participants in the study included 36 informants, managers, experts associated with health and surveillance of communicable diseases that were selected using targeted sampling and with diverse backgrounds and work experience (different experiences in primary health surveillance and treatment, Ministry levels, university staff and operations (hospitals and health centers) and sampling was continued until arrive to data saturation. Results: Interviews were analyzed after the elimination of duplicate codes and integration of them. Finally, 73 codes were acquired and categorized in 6 major themes and 21 levels. The main themes included: policy making and planning, development of resources, organizing, collaboration and participation, surveillance process, and monitoring and evaluation of the surveillance system. In point of interviewees, attention to these themes is necessary to develop effective and efficient surveillance system for communicable diseases. Conclusion: Surveillance system in hospitals is important in developing proper macro - policies in health sector, adoption of health related decisions and preventive plans appropriate to the existing situation. Compilation, changing, improving, monitoring and continuous updating of surveillance systems can play a significant role in its efficiency and effectiveness. In the meantime, policy makers’ and senior managers’ support in development and implementation of communicable disease surveillance’ plans and their reporting plays a key and core role.

To avoid the limitation of common route planning method to blindly pursue higher Machine Intelligence and autoimmunization, this paper presents a human-machine cooperation route planning method. The proposed method includes a new A* path searing strategy based on dynamic heuristic searching and a human cooperated decision strategy to prune searching area. It can overcome the shortage of A* algorithm to fall into a local long term searching. Experiments showed that this method can quickly plan a feasible route to meet the macro-policy thinking.

Single room occupancy (SRO) hotels as mental health risk environments among impoverished women: the intersection of policy, drug use, trauma, and urban space.

Due to the significantly high levels of comorbid substance use and mental health diagnosis among urban poor populations, examining the intersection of drug policy and place requires a consideration of the role of housing in drug user mental health. In San Francisco, geographic boundedness and progressive health and housing polices have coalesced to make single room occupancy hotels (SROs) a key urban built environment used to house poor populations with co-occurring drug use and mental health issues. Unstably housed women who use illicit drugs have high rates of lifetime and current trauma, which manifests in disproportionately high rates of post-traumatic stress disorder (PTSD), anxiety, and depression when compared to stably housed women. We report data from a qualitative interview study (n=30) and four years of ethnography conducted with housing policy makers and unstably housed women who use drugs and live in SROs. Women in the study lived in a range of SRO built environments, from publicly funded, newly built SROs to privately owned, dilapidated buildings, which presented a rich opportunity for ethnographic comparison. Applying Rhodes et al.'s framework of socio-structural vulnerability, we explore how SROs can operate as "mental health risk environments" in which macro-structural factors (housing policies shaping the built environment) interact with meso-level factors (social relations within SROs) and micro-level, behavioral coping strategies to impact women's mental health. The degree to which SRO built environments were "trauma-sensitive" at the macro level significantly influenced women's mental health at meso- and micro-levels. Women who were living in SROs which exacerbated fear and anxiety attempted, with limited success, to deploy strategies on the meso- and micro-level to manage their mental health symptoms. Study findings underscore the importance of housing polices which consider substance use in the context of current and cumulative trauma experiences in order to improve quality of life and mental health for unstably housed women.

In this paper, a step-by-step analysis-through-separation method under the navigation of multi-step IR macro-fingerprint (FT-IR integrated with second derivative IR (SD-IR) and 2DCOS-IR) was developed for comprehensively characterizing the hierarchical chemical fingerprints of licorice from entirety to single active components. Subsequently, the chemical profile variation rules of three parts (flavonoids, saponins and saccharides) in the separation process were holistically revealed and the number of matching peaks and correlation coefficients with standards of pure compounds was increasing along the extracting directions. The findings were supported by UPLC results and a verification experiment of aqueous separation process. It has been demonstrated that the developed multi-step IR macro-fingerprint analysis-through-separation approach could be a rapid, effective and integrated method not only for objectively providing comprehensive chemical characterization of licorice and all its separated parts, but also for rapidly revealing the global enrichment trend of the active components in licorice separation process.

Knowledge translation at the macro level: legal and ethical considerations.

2007-11-01

Macro-level legal and ethical issues play a significant role in the successful translation of knowledge into practice. The medicolegal milieu, in particular, can promote clinical inertia and stifle innovation. Embracing new clinical practice guidelines and best practice models has not protected physicians from superfluous torts; in some cases, emerging evidence has been used as the dagger of trial lawyers rather than the scalpel of physicians. Beyond the legal challenges are overarching justice issues that frame the broad goals of knowledge translation (KT) and technology diffusion. Optimal implementation of the latest evidence requires attention to be paid to the context of the candidate community and the key opinion leaders therein, characterized by the "8Ps" (public, patients, press, physicians, policy makers, private sector, payers, and public health). Ethical and equitable KT also accounts for the global burdens and benefits of implementing innovation such that disparities and gaps in health experienced by the least advantaged are prioritized. Researchers and thought leaders must attend to questions of fairness, economics, and legal risk when investigating ways to promote equity-oriented KT.

Negotiating jurisdiction in the workplace: a multiple-case study of nurse prescribing in hospital settings.

This paper reports on a multiple-case study of prescribing by nurse specialists in Dutch hospital settings. Most analyses of interprofessional negotiations over professional boundaries take a macro sociological approach and ignore workplace jurisdictions. Yet boundary blurring takes place and healthcare professionals renegotiate formal policies in the workplace. This paper studies the division of jurisdictional control over prescribing between nurse specialists and medical specialists in the workplace, and examines the relationship between workplace jurisdiction and legal jurisdiction over prescribing. Data collection took place in the Netherlands during the first half of 2013. The study used in-depth interviews with fifteen nurse specialists and fourteen medical specialists, non-participant observation of nurse specialists' prescribing consultations and document analysis. Great variety was found in the extent to which and way in which nurse specialists' legal prescriptive authority had been implemented. These findings suggest that there is considerable discrepancy between the division of jurisdictional control over prescribing at the macro (legal) level and the division at the micro (workplace) level.

Spatial access disparities to primary health care in rural and remote Australia.

McGrail, Matthew Richard; Humphreys, John Stirling

2015-11-04

Poor spatial access to health care remains a key issue for rural populations worldwide. Whilst geographic information systems (GIS) have enabled the development of more sophisticated access measures, they are yet to be adopted into health policy and workforce planning. This paper provides and tests a new national-level approach to measuring primary health care (PHC) access for rural Australia, suitable for use in macro-level health policy. The new index was constructed using a modified two-step floating catchment area method framework and the smallest available geographic unit. Primary health care spatial access was operationalised using three broad components: availability of PHC (general practitioner) services; proximity of populations to PHC services; and PHC needs of the population. Data used in its measurement were specifically chosen for accuracy, reliability and ongoing availability for small areas. The resultant index reveals spatial disparities of access to PHC across rural Australia. While generally more remote areas experienced poorer access than more populated rural areas, there were numerous exceptions to this generalisation, with some rural areas close to metropolitan areas having very poor access and some increasingly remote areas having relatively good access. This new index provides a geographically-sensitive measure of access, which is readily updateable and enables a fine granulation of access disparities. Such an index can underpin national rural health programmes and policies designed to improve rural workforce recruitment and retention, and, importantly, health service planning and resource allocation decisions designed to improve equity of PHC access.

Accelerating Progress in Eating Disorders Prevention: A Call for Policy Translation Research and Training.

PubMed

Austin, S Bryn

2016-01-01

The public health burden of eating disorders is well documented, and over the past several decades, researchers have made important advances in the prevention of eating disorders and related problems with body image. Despite these advances, however, several critical limitations to the approaches developed to date leave the field far from achieving the large-scale impact that is needed. This commentary provides a brief review of what achievements in prevention have been made and identifies the gaps that limit the potential for greater impact on population health. A plan is then offered with specific action steps to accelerate progress in high-impact prevention, most compellingly by promoting a shift in priorities to policy translation research and training for scholars through the adoption of a triggers-to-action framework. Finally, the commentary provides an example of the application of the triggers-to-action framework as practiced at the Strategic Training Initiative for the Prevention of Eating Disorders, a program based at the Harvard T. H. Chan School of Public Health and Boston Children's Hospital. Much has been achieved in the nearly 30 years of research carried out for the prevention of eating disorders and body image problems, but several critical limitations undermine the field's potential for meaningful impact. Through a shift in the field's priorities to policy translation research and training with an emphasis on macro-environmental influences, the pace of progress in prevention can be accelerated and the potential for large-scale impact substantially improved.

Potential macro-detritivore range expansion into the subarctic stimulates litter decomposition: a new positive feedback mechanism to climate change?

As a result of low decomposition rates, high-latitude ecosystems store large amounts of carbon. Litter decomposition in these ecosystems is constrained by harsh abiotic conditions, but also by the absence of macro-detritivores. We have studied the potential effects of their climate change-driven northward range expansion on the decomposition of two contrasting subarctic litter types. Litter of Alnus incana and Betula pubescens was incubated in microcosms together with monocultures and all possible combinations of three functionally different macro-detritivores (the earthworm Lumbricus rubellus, isopod Oniscus asellus, and millipede Julus scandinavius). Our results show that these macro-detritivores stimulated decomposition, especially of the high-quality A. incana litter and that the macro-detritivores tested differed in their decomposition-stimulating effects, with earthworms having the largest influence. Decomposition processes increased with increasing number of macro-detritivore species, and positive net diveristy effects occurred in several macro-detritivore treatments. However, after correction for macro-detritivore biomass, all interspecific differences in macro-detritivore effects, as well as the positive effects of species number on subarctic litter decomposition disappeared. The net diversity effects also appeared to be driven by variation in biomass, with a possible exception of net diversity effects in mass loss. Based on these results, we conclude that the expected climate change-induced range expansion of macro-detritivores into subarctic regions is likely to result in accelerated decomposition rates. Our results also indicate that the magnitude of macro-detritivore effects on subarctic decomposition will mainly depend on macro-detritivore biomass, rather than on macro-detritivore species number or identity.

A qualitative case study in the social capital of co-professional collaborative co-practice for children with speech, language and communication needs.

Effective co-practice is essential to deliver services for children with speech, language and communication needs (SLCN). The necessary skills, knowledge and resources are distributed amongst professionals and agencies. Co-practice is complex and a number of barriers, such as 'border disputes' and poor awareness of respective priorities, have been identified. However social-relational aspects of co-practice have not been explored in sufficient depth to make recommendations for improvements in policy and practice. Here we apply social capital theory to data from practitioners: an analytical framework with the potential to move beyond descriptions of socio-cultural phenomena to inform change. Co-practice in a local authority site was examined to understand: (1) the range of social capital relations extant in the site's co-practice; (2) how these relations affected the abilities of the network to collaborate; (3) whether previously identified barriers to co-practice remain; (4) the nature of any new complexities that may have emerged; and (5) how inter-professional social capital might be fostered. A qualitative case study of SLCN provision within one local authority in England and its linked NHS partner was completed through face-to-face semi-structured interviews with professionals working with children with SLCN across the authority. Interviews, exploring barriers and facilitators to interagency working and social capital themes, were transcribed, subjected to thematic analysis using iterative methods and a thematic framework derived. We identified a number of characteristics important for the effective development of trust, reciprocity and negotiated co-practice at different levels of social capital networks: macro-service governance and policy; meso-school sites; and micro-intra-practitioner knowledge and skills. Barriers to co-practice differed from those found in earlier studies. Some negative aspects of complexity were evident, but only where networked professionalism and trust was absent between professions. Where practitioners embraced and services and systems enabled more fluid forms of collaboration, then trust and reciprocity developed. Highly collaborative forms of co-practice, inherently more complex at the service governance, macro-level, bring benefits. At the meso-level of the school and support team network there was greater capacity to individualize co-practice to the needs of the child. Capacity was increased at the micro-level of knowledge and skills to harness the overall resource distributed amongst members of the inter-professional team. The development of social capital, networks of trust across SLCN support teams, should be a priority at all levels-for practitioners, services, commissioners and schools. © 2016 Royal College of Speech and Language Therapists.

Worker health is good for the economy: union density and psychosocial safety climate as determinants of country differences in worker health and productivity in 31 European countries.

Dollard, Maureen F; Neser, Daniel Y

Work stress is recognized globally as a social determinant of worker health. Therefore we explored whether work stress related factors explained national differences in health and productivity (gross domestic product (GDP)). We proposed a national worker health productivity model whereby macro market power factors (i.e. union density), influence national worker health and GDP via work psychosocial factors and income inequality. We combined five different data sets canvasing 31 wealthy European countries. Aggregated worker self-reported health accounted for 13 per cent of the variance in national life expectancy and in national gross domestic product (GDP). The most important factors explaining worker self-reported health and GDP between nations were two levels of labor protection, macro-level (union density), and organizational-level (psychosocial safety climate, PSC, i.e. the extent of management concern for worker psychological health). The majority of countries with the highest levels of union density and PSC (i.e., workplace protections) were Social Democratic in nature (i.e., Sweden, Finland, Denmark, Norway). Results support a type of society explanation that social and economic factors (e.g., welfare regimes, work related policies) in concert with political power agents at a national level explain in part national differences in workplace protection (PSC) that are important for worker health and productivity. Attention should be given across all countries, to national policies to improve worker health, by bolstering national and local democratic processes and representation to address and implement policies for psychosocial risk factors for work stress, bullying and violence. Results suggest worker health is good for the economy, and should be considered in national health and productivity accounting. Eroding unionism may not be good for worker health or the economy either. Copyright © 2013 Elsevier Ltd. All rights reserved.

Unexplained high thyroid stimulating hormone: a "BIG" problem.

PubMed

Mendoza, Heidi; Connacher, Alan; Srivastava, Rajeev

2009-01-01

Macro-hormones and macro-enzymes are high molecular weight conjugates of hormones or enzymes, respectively, often with immunoglobulins. These are referred to as macromolecular complexes, and may cause artefactually elevated biochemical tests results. Macro enzymes of the most commonly measured serum enzymes have been identified and are recognised as a source of elevated measurements that may cause diagnostic confusion; macro-creatine kinase and macro-amylase are the two better known macro-enzymes in clinical practice. Literature on macro-hormones is largely restricted to macro-prolactin. We present a case of a clinically euthyroid patient, who had persistently elevated thyroid stimulating hormone (TSH) but free thyroxine within the reference limits. She underwent repeated thyroid investigations and thyroid hormone interference studies, until macro-TSH was identified as the most likely cause of unexplained elevated TSH. Following the identification and characterisation of this biochemical abnormality, she is no longer subject to repeated blood tests for assessment of thyroid function; the patient currently remains clinically euthyroid.

Assessment of macro-uniformity is a capability that is important for the development and manufacture of printer products. Our goal is to develop a metric that will predict macro-uniformity, as judged by human subjects, by scanning and analyzing printed pages. We consider two different machine learning frameworks for the metric: linear regression and the support vector machine. We have implemented the image quality ruler, based on the recommendations of the INCITS W1.1 macro-uniformity team. Using 12 subjects at Purdue University and 20 subjects at Lexmark, evenly balanced with respect to gender, we conducted subjective evaluations with a set of 35 uniform b/w prints from seven different printers with five levels of tint coverage. Our results suggest that the image quality ruler method provides a reliable means to assess macro-uniformity. We then defined and implemented separate features to measure graininess, mottle, large area variation, jitter, and large-scale non-uniformity. The algorithms that we used are largely based on ISO image quality standards. Finally, we used these features computed for a set of test pages and the subjects' image quality ruler assessments of these pages to train the two different predictors - one based on linear regression and the other based on the support vector machine (SVM). Using five-fold cross-validation, we confirmed the efficacy of our predictor.

A molecular signaling approach to linking intraspecific variation and macro-evolutionary patterns.

Macro-evolutionary comparisons are a valued tool in evolutionary biology. Nevertheless, our understanding of how systems involved in molecular signaling change in concert with phenotypic diversification has lagged. We argue that integrating our understanding of the evolution of molecular signaling systems with phylogenetic comparative methods is an important step toward understanding the processes linking variation among individuals with variation among species. Focusing mostly on the endocrine system, we discuss how the complexity and mechanistic nature of molecular signaling systems may influence the application and interpretation of macro-evolutionary comparisons. We also detail five hypotheses concerning the role that physiological mechanisms can play in shaping macro-evolutionary patterns, and discuss ways in which these hypotheses could influence phenotypic diversification. Finally, we review a series of tools able to analyze the complexity of physiological systems and the way they change in concert with the phenotypes for which they coordinate development. © The Author 2014.

This article is one of three synthesis reports resulting from an integrated assessment (IA) of artisanal and small-scale gold mining (ASGM) in Ghana. Given the complexities that involve multiple drivers and diverse disciplines influencing ASGM, an IA framework was used to analyze economic, social, health, and environmental data and to co-develop evidence-based responses in collaboration with pertinent stakeholders. We look at both micro- and macro-economic processes surrounding ASGM, including causes, challenges, and consequences. At the micro-level, social and economic evidence suggests that the principal reasons whereby most people engage in ASGM involve "push" factors aimed at meeting livelihood goals. ASGM provides an important source of income for both proximate and distant communities, representing a means of survival for impoverished farmers as well as an engine for small business growth. However, miners and their families often end up in a "poverty trap" of low productivity and indebtedness, which reduce even further their economic options. At a macro level, Ghana's ASGM activities contribute significantly to the national economy even though they are sometimes operating illegally and at a disadvantage compared to large-scale industrial mining companies. Nevertheless, complex issues of land tenure, social stability, mining regulation and taxation, and environmental degradation undermine the viability and sustainability of ASGM as a livelihood strategy. Although more research is needed to understand these complex relationships, we point to key findings and insights from social science and economics research that can guide policies and actions aimed to address the unique challenges of ASGM in Ghana and elsewhere.

Dimensionality can have a profound impact on stiffness-mediated differentiation of mesenchymal stem cells (MSCs). However, while we have begun to understand cellular response when encapsulated within 3D substrates, the behavior of cells within macro-porous substrates is relatively underexplored. The goal of this study was to determine the influence of macro-porous topographies on stiffness-mediated differentiation of MSCs. We developed macro-porous recombinant elastin-like protein (ELP) substrates that allow independent control of mechanical properties and ligand chemistry. We then used computational modeling to probe the impact of pore topography on the mechanical stimulus that cells are exposed to within these substrates, and finally we investigated stiffness induced biases towards adipogenic and osteogenic differentiation of MSCs within macro-porous substrates. Computational modeling revealed that there is significant heterogeneity in the mechanical stimuli that cells are exposed to within porous substrates and that this heterogeneity is predominantly due to the wide range of possible cellular orientations within the pores. Surprisingly, MSCs grown within 3D porous substrates respond to increasing substrate stiffness by up-regulating both osteogenesis and adipogenesis. These results demonstrate that within porous substrates the behavior of MSCs diverges from previously observed responses to substrate stiffness, emphasizing the importance of topography as a determinant of cellular behavior.

Critical water resources face the effects of historic drought, increased demand, and potential contamination, the need has never been greater to develop resources to effectively communicate conservation and protection across a broad audience and geographical area. The Watermark application and macro-analysis methodology merges topical analysis of context rich corpus from policy texts with multi-attributed solution sets from integrated models of water resource and other subsystems, such as mineral, food, energy, or environmental systems to construct a scalable, robust, and reproducible approach for identifying links between policy and science knowledge bases. The Watermark application is an open-source, interactive workspace to support science-based visualization and decision making. Designed with generalization in mind, Watermark is a flexible platform that allows for data analysis and inclusion of large datasets with an interactive front-end capable of connecting with other applications as well as advanced computing resources. In addition, the Watermark analysis methodology offers functionality that streamlines communication with non-technical users for policy, education, or engagement with groups around scientific topics of societal relevance. The technology stack for Watermark was selected with the goal of creating a robust and dynamic modular codebase that can be adjusted to fit many use cases and scale to support usage loads that range between simple data display to complex scientific simulation-based modelling and analytics. The methodology uses to topical analysis and simulation-optimization to systematically analyze the policy and management realities of resource systems and explicitly connect the social and problem contexts with science-based and engineering knowledge from models. A case example demonstrates use in a complex groundwater resources management study highlighting multi-criteria spatial decision making and uncertainty comparisons.

A modeling comparison of deep greenhouse gas emissions reduction scenarios by 2030 in California

DOE PAGES

Yeh, Sonia; Yang, Christopher; Gibbs, Michael; ...

2016-10-21

California aims to reduce greenhouse gas (GHG) emissions to 40% below 1990 levels by 2030. We compare six energy models that have played various roles in informing the state policymakers in setting climate policy goals and targets. These models adopt a range of modeling structures, including stock-turnover back-casting models, a least-cost optimization model, macroeconomic/macro-econometric models, and an electricity dispatch model. Results from these models provide useful insights in terms of the transformations in the energy system required, including efficiency improvements in cars, trucks, and buildings, electrification of end-uses, low- or zero-carbon electricity and fuels, aggressive adoptions of zero-emission vehicles (ZEVs),more » demand reduction, and large reductions of non-energy GHG emissions. Some of these studies also suggest that the direct economic costs can be fairly modest or even generate net savings, while the indirect macroeconomic benefits are large, as shifts in employment and capital investments could have higher economic returns than conventional energy expenditures. These models, however, often assume perfect markets, perfect competition, and zero transaction costs. They also do not provide specific policy guidance on how these transformative changes can be achieved. Greater emphasis on modeling uncertainty, consumer behaviors, heterogeneity of impacts, and spatial modeling would further enhance policymakers' ability to design more effective and targeted policies. Here, this paper presents an example of how policymakers, energy system modelers and stakeholders interact and work together to develop and evaluate long-term state climate policy targets. Lastly, even though this paper focuses on California, the process of dialogue and interactions, modeling results, and lessons learned can be generally adopted across different regions and scales.« less

The ?new? economics of education: Towards a ?unified? macro/micro-educational planning policy

NASA Astrophysics Data System (ADS)

Kraft, Richard H.; Nakib, Yasser

1991-09-01

What has become the "classical" theory of the economics of education, first systematically laid down in the 1960s, is based on analysis of measurable variables. The concept of investment in human capital supposes that higher funding for education will increase productivity and income. Estimates of cost-effectiveness and returns to investment based on notional income foregone, have been features of this approach. Now, with a growing realization of the failure of the classical theory to deal with "realities" in the education market and to offer effective policy recommendations, other ideologies have again become more visible. The lack of attention given to the labor demand side of the education-earnings equation, and the inability of theoretical models to capture all complex variables in all sectors of the labor market, have been criticized. Also, it has again been recognized that education has a socialization role. The phenomena of undereducation and over-education have been investigated, and attention has been given to the implications of social conflicts and structural changes in the labor market. If human competences are to be developed, it is necessary to look beyond the classical model of the economics of education to microeconomic analysis and to economic and social conditions which will act as incentives.

Physicians’ Ethical Dilemmas in the Context of Anti-Doping Practices

2016-01-01

The World Anti-Doping Code states that, there is an intrinsic value about sports that is the celebration of the human spirit, body and mind, and is reflected in values other than winning or being the first in any sports game. The spirit of sports includes ethics, fair play and honesty. Anti-doping practices are based on this ethical ground and supported all through the world. However, recently with the arguments that there is no substantial definition of the term “spirit of sports”, and that the fights against doping is based on questionable ethical grounds consisting of dubious claims about fairness in sports and terms such as “level playing field”. Medical ethics is involved in this discussion because of the crucial role of physicians in anti-doping policies and practices as well as developing and administering ergogenic substances or methods for athletes. This role of physicians raises ethical questions regarding physician-patient relationship, principle of non-male ficence, privacy and confidentiality of patient, and fairness and justice in the macro allocation of resources. The aim of this paper is to discuss ethical arguments on anti-doping practices and policies and, to further evaluate current anti-doping practices in the context of medical ethics. PMID:28070567

The formal-informal patient payment mix in European countries. Governance, economics, culture or all of these?

2013-12-01

Cost-sharing for health care is high on the policy agenda in many European countries that struggle with deficits in their public budget. However, such policy often meets with public opposition, which might delay or even prevent its implementation. Increased reliance on patient payments may also have adverse equity effects, especially in countries where informal patient payments are widespread. The factors which might influence the presence of both, formal and informal payments can be found in economic, governance and cultural differences between countries. The aim of this paper is to review the formal-informal payment mix in Europe and to outline factors associated with this mix. We use quantitative analyses of macro-data for 35 European countries and a qualitative description of selected country experiences. The results suggest that the presence of obligatory cost-sharing for health care services is associated with governance factors, while informal patient payments are a multi-cause phenomenon. A consensus-based policy, supported by evidence and stakeholders' engagement, might contribute to a more sustainable patient payment policy. In some European countries, the implementation of cost-sharing requires policy actions to reduce other patient payment obligations, including measures to eliminate informal payments.

There is growing recognition that implementation of low-carbon policies in urban passenger transport has near-term health co-benefits through increased physical activity and improved air quality. Nevertheless, co-benefits and related cost reductions are often not taken into account in decision processes, likely because they are not easy to capture. In an interdisciplinary multi-model approach we address this gap, investigating the co-benefits resulting from increased physical activity and improved air quality due to climate mitigation policies for three urban areas. Additionally we take a (macro-)economic perspective, since that is the ultimate interest of policy-makers. Methodologically, we link a transport modelling tool, a transport emission model, an emission dispersion model, a health model and a macroeconomic Computable General Equilibrium (CGE) model to analyze three climate change mitigation scenarios. We show that higher levels of physical exercise and reduced exposure to pollutants due to mitigation measures substantially decrease morbidity and mortality. Expenditures are mainly born by the public sector but are mostly offset by the emerging co-benefits. Our macroeconomic results indicate a strong positive welfare effect, yet with slightly negative GDP and employment effects. We conclude that considering economic co-benefits of climate change mitigation policies in urban mobility can be put forward as a forceful argument for policy makers to take action. PMID:29710784

2017-06-01

Macro-sieve electrodes were implanted in the sciatic nerve of five adult male Lewis rats following spinal cord injury to assess the ability of the macro-sieve electrode to interface regenerated peripheral nerve fibers post-spinal cord injury. Each spinal cord injury was performed via right lateral hemisection of the cord at the T 9-10 site. Five months post-implantation, the ability of the macro-sieve electrode to interface the regenerated nerve was assessed by stimulating through the macro-sieve electrode and recording both electromyography signals and evoked muscle force from distal musculature. Electromyography measurements were recorded from the tibialis anterior and gastrocnemius muscles, while evoked muscle force measurements were recorded from the tibialis anterior, extensor digitorum longus, and gastrocnemius muscles. The macro-sieve electrode and regenerated sciatic nerve were then explanted for histological evaluation. Successful sciatic nerve regeneration across the macro-sieve electrode interface following spinal cord injury was seen in all five animals. Recorded electromyography signals and muscle force recordings obtained through macro-sieve electrode stimulation confirm the ability of the macro-sieve electrode to successfully recruit distal musculature in this injury model. Taken together, these results demonstrate the macro-sieve electrode as a viable interface for peripheral nerve stimulation in the context of spinal cord injury.

Clinimetrics and clinical psychometrics: macro- and micro-analysis.

PubMed

Tomba, Elena; Bech, Per

2012-01-01

Clinimetrics was introduced three decades ago to specify the domain of clinical markers in clinical medicine (indexes or rating scales). In this perspective, clinical validity is the platform for selecting the various indexes or rating scales (macro-analysis). Psychometric validation of these indexes or rating scales is the measuring aspect (micro-analysis). Clinical judgment analysis by experienced psychiatrists is included in the macro-analysis and the item response theory models are especially preferred in the micro-analysis when using the total score as a sufficient statistic. Clinical assessment tools covering severity of illness scales, prognostic measures, issues of co-morbidity, longitudinal assessments, recovery, stressors, lifestyle, psychological well-being, and illness behavior have been identified. The constructive dialogue in clinimetrics between clinical judgment and psychometric validation procedures is outlined for generating developments of clinical practice in psychiatry.

The macro-pore sizes of porous scaffold play a key role for regulating ectopic osteogenesis and angiogenesis but many researches ignored the influence of interconnection between macro-pores with different sizes. In order to accurately reveal the relationship between ectopic osteogenesis and macro-pore sizes in dorsal muscle and abdominal cavities of dogs, hydroxyapatite (HA) scaffolds with three different macro-pore sizes of 500–650, 750–900 and 1100–1250 µm were prepared via sugar spheres-leaching process, which also had similar interconnecting structure determined by keeping the d/s ratio of interconnecting window diameter to macro-pore size constant. The permeability test showed that the seepage flow of fluid through the porous scaffolds increased with the increase of macro-pore sizes. The cell growth in three scaffolds was not affected by the macro-pore sizes. The in vivo ectopic implantation results indicated that the macro-pore sizes of HA scaffolds with the similar interconnecting structure have impact not only the speed of osteogenesis and angiogenesis but also the space distribution of newly formed bone. The scaffold with macro-pore sizes of 750–900 µm exhibited much faster angiogenesis and osteogenesis, and much more uniformly distribution of new bone than those with other macro-pore sizes. This work illustrates the importance of a suitable macro-pore sizes in HA scaffolds with the similar interconnecting structure which provides the environment for ectopic osteogenesis and angiogenesis.

TSH is a sensitive indicator of thyroid function. In subclinical hypothyroidism, however, serum TSH concentrations are elevated despite normal thyroid hormone levels, and macro TSH is one of the causes. This study aimed to clarify the prevalence and nature of macro TSH in patients with subclinical hypothyroidism. We conducted a 2-year cross-sectional observational study. We included 681 patients with subclinical hypothyroidism and 38 patients with overt hypothyroidism (controls). Macro TSH was screened by polyethylene glycol (PEG) method and analysed by gel filtration chromatography and bioassays. Among 681 serum samples, 117 exhibited PEG-precipitable TSH ratios greater than 75% (mean + 1·5 SD in controls) and were subjected to gel filtration chromatography. TSH was eluted at a position greater than 100 kDa in 11 patients with subclinical hypothyroidism (1·62%); these patients were diagnosed with macro TSH. The nature of macro TSH included eight anti-TSH autoantibodies of IgG class, two non-IgG-associated and one human anti-mouse antibody (HAMA). Macro TSH showed low bioactivity. Macro TSH was heterogeneous, but it is mostly comprised of TSH and anti-TSH autoantibodies. When PEG-precipitable TSH exceeds 90% in serum samples with TSH above 10 mU/l, clinicians should strongly suspect the presence of macro TSH and confirm it by gel chromatography. Because macro TSH exhibited low bioactivity, thyroid hormone replacement therapy may not be required in patients with subclinical hypothyroidism due to macro TSH except for those with high serum free TSH levels. © 2014 John Wiley & Sons Ltd.

Recent developments in spectroscopic imaging techniques for historical paintings - A review

2017-10-01

This paper provides an overview over the application of scanning macro-XRF with mobile instruments for the investigation of historical paintings. The method is compared to synchrotron based macro-XRF imaging and Neutron Activation Auto-Radiography. Full-Field XRF imaging instruments, a potential future alternative to scanning macro-XRF, and confocal XRF, providing complementary depth profiles and developing into a 3D imaging technique itself, are described with the focus on investigations of historical paintings. Recent developments of X-ray radiography are presented and the investigation of cultural heritage objects other than paintings by MA-XRF is summarized. In parallel to XRF, hyperspectral imaging in the visible and range has developed into a technique with comparable capabilities, providing insight in chemical compounds, where XRF imaging identifies the distribution of elements. Due to the complementary nature of these techniques the latter is summarized. Further, progress and state of the art in data evaluation for spectroscopic imaging is discussed. In general it could be observed that technical capabilities in MA-XRF and hyperspectral imaging have reached a plateau and that with the availability of commercial instruments the focus of recent studies has shifted from the development of methods to applications of the instruments. Further, that while simple instruments are easily available with medium budgets only few groups have high-end instrumentation available, bought or in-house built.

The application of epidemiology in national veterinary services: Challenges and threats in Brazil.

Gonçalves, Vitor Salvador Picão; de Moraes, Geraldo Marcos

2017-02-01

The application of epidemiology in national veterinary services must take place at the interface between science and politics. Animal health policy development and implementation require attention to macro-epidemiology, the study of economic, social and policy inputs that affect the distribution and impact of animal or human disease at the national level. The world has changed fast over the last three decades including the delivery of veterinary services, their remit and the challenges addressed by public and animal health policies. Rethinking the role of public services and how to make public programs more efficient has been at the heart of the political discussion. The WTO through its SPS Agreement has changed the way in which national veterinary services operate and how trade decisions are made. Most low and middle income countries are still struggling to keep up with the new international scene. Some of these countries, such as Brazil, have very important livestock industries and are key to the global food systems. Over the last two decades, Brazil became a leading player in exports of livestock products, including poultry, and this created a strong pressure on the national veterinary services to respond to trade demands, leading to focus animal health policies on the export-driven sector. During the same period, Brazil has gone a long way in the direction of integrating epidemiology with veterinary services. Epidemiology groups grew at main universities and have been working with government to provide support to animal health policy. The scope and quality of the applied epidemiological work improved and focused on complex data analysis and development of technologies and tools to solve specific disease problems. Many public veterinary officers were trained in modern epidemiological methods. However, there are important institutional bottlenecks that limit the impact of epidemiology in evidence-based decision making. More complex challenges require high levels of expertise in veterinary epidemiology, as well as institutional models that provide an appropriate environment for building and sustaining capacity in national veterinary services. Integrating epidemiology with animal health policy is a great opportunity if epidemiologists can understand the real issues, including the socio-economic dimensions of disease management, and focus on innovation and production of knowledge. It may be a trap if epidemiologists are restricted to answering specific decision-making questions and policy makers perceive their role exclusively as data analysts or providers of technological solutions. Fostering solutions for complex issues is key to successful integration with policy making. Copyright © 2016 Elsevier B.V. All rights reserved.

Women's dreaming: women, sexuality and development.

PubMed

Reid, E

1996-01-01

This essay opens by invoking the dreams of women that arise from their life experiences and lead women, despite their powerlessness, to desire to create a different kind of society. The essay continues by exploring the relationship between analysis and practice and the contention that analysis of a problem shapes development practice, social policy, research priorities, and activism. Poverty provides an example of a complex, chaotic phenomenon that is often reduced to simplistic, measurable variables such as income or consumption deprivation. Attention is then paid to the population debate where linkages between the analytical framework and program development are clear. These simplified linkages led to macro analysis of events played out on the micro level and to the choice of women rather than men as the most effective change agents. The 1994 International Conference on Population and Development, however, gave rise to a new analytical framework emphasizing women's empowerment, women's health, women's rights, and men's participation and responsibility. This approach embraces the complexity of the situation and, thus, provides a road map for effective programs and policies. The next section of the essay considers gender analysis and how this concept leads to a demand on the part of women for access to men's privileges and a climate of confrontation arising from this demand. The inadequacies of using a woman-centered gender analysis as a framework for understanding male behavior are also discussed. Alternative concepts from the feminist movement are explored for their usefulness in generating social change, and the efforts of the Bangladesh Rural Achievement Committee to improve female literacy are used as an example of the value of cooperative, consciousness-raising groups. It is concluded that radical changes will be required to realize women's dreams of social changes.

Macro creatine kinase: determination and differentiation of two types by their activation energies

Determination of the MB isoenzyme of creatine kinase in patients with acute myocardial infarction may be disturbed by the presence of macro creatine kinase. The relative molecular mass of this form of creatine kinase in human serum is at least threefold that of the ordinary enzyme, and it is more thermostable. Here we describe our method for determination of macro creatine kinases and an easy-to-perform test for differentiating two forms of macro creatine kinase, based on their distinct activation energies. The activation energies of serum enzymes are mostly in the range of 40-65 kJ/mol of substrate. Unlike normal cytoplasmatic creatinemore » kinases and IgG-linked CK-BB (macro creatine kinase type 1) a second form of macro creatine kinase (macro creatine kinase type 2) shows activation energies greater than 80 kJ/mol of substrate. The exact composition of macro creatine kinase type 2 is still unknown, but there is good reason to believe that it is of mitochondrial origin.« less

An empirical tool to evaluate the safety of cyclists: Community based, macro-level collision prediction models using negative binomial regression.

PubMed

Wei, Feng; Lovegrove, Gordon

2013-12-01

Today, North American governments are more willing to consider compact neighborhoods with increased use of sustainable transportation modes. Bicycling, one of the most effective modes for short trips with distances less than 5km is being encouraged. However, as vulnerable road users (VRUs), cyclists are more likely to be injured when involved in collisions. In order to create a safe road environment for them, evaluating cyclists' road safety at a macro level in a proactive way is necessary. In this paper, different generalized linear regression methods for collision prediction model (CPM) development are reviewed and previous studies on micro-level and macro-level bicycle-related CPMs are summarized. On the basis of insights gained in the exploration stage, this paper also reports on efforts to develop negative binomial models for bicycle-auto collisions at a community-based, macro-level. Data came from the Central Okanagan Regional District (CORD), of British Columbia, Canada. The model results revealed two types of statistical associations between collisions and each explanatory variable: (1) An increase in bicycle-auto collisions is associated with an increase in total lane kilometers (TLKM), bicycle lane kilometers (BLKM), bus stops (BS), traffic signals (SIG), intersection density (INTD), and arterial-local intersection percentage (IALP). (2) A decrease in bicycle collisions was found to be associated with an increase in the number of drive commuters (DRIVE), and in the percentage of drive commuters (DRP). These results support our hypothesis that in North America, with its current low levels of bicycle use (<4%), we can initially expect to see an increase in bicycle collisions as cycle mode share increases. However, as bicycle mode share increases beyond some unknown 'critical' level, our hypothesis also predicts a net safety improvement. To test this hypothesis and to further explore the statistical relationships between bicycle mode split and overall road safety, future research needs to pursue further development and application of community-based, macro-level CPMs. Copyright © 2012.

The present work endeavors to explore the asymmetric effect of coal price on the China's macro economy by applying nonlinear autoregressive distributed lag (NARDL) model for the period of January 2005 to June 2015. The obtained results indicate that the coal price has a strong asymmetric effect on China's macro economy in the long-run. Namely one percent increase in coal price leads to 0.6194 percent of the China's macro economy increase; and while the coal price is reduces by 1 percent, the China's macro economy will decrease by 0.008 percent. These data indicate that when coal price rises, the effect on China's macro economy is far greater than the price decline. In the short-run, coal price fluctuation has a positive effect on the China's macro economy.

On the other hand, the incidence of TB worldwide decreases at a lower rate than the intended targets, and it is seen that the targets set for 2015 will not be achieved at the global level. According to the WHO, failure to achieve the targets in TB control results from “resource constraints”, “conflict and instability” and “generalized human immunodeficiency virus epidemics”. This article is aimed to maintain an ethical debate in TB control and to investigate the WHO’s TB control policy and question the reasons for failure of this policy. Within the scope of this article; the TB of TB control was problematized at macro political level within the context of philosophy, while the approach of health care staff to TB patients was analysed at micro level within the context of professional ethics.

[Economic sustainability of therapies: considerations following the introduction of new drugs for hepatitis C virus].

PubMed

Spandonaro, Federico

2014-06-01

The availability of new drugs potentially able to drastically reduce the burden of very common infectious diseases like hepatitis C requires the national health services to take a different decision-making process. On the one hand, there is an evident financial issue; on the other hand, low budgets may undermine a system that provides universal access to healthcare. It is unrealistic to expect retrieving the financial resources needed from negotiating prices with pharmaceutical companies, resource reallocation or a reduction in economic waste. The national health systems need a new priority setting and a National fund for healthcare innovation should be built. Novel drugs should be evaluated balancing availability and opportunity, forcing to rethink the decision-making processes. Macro- (re-prioritization of interventions) and micro-policies (the introduction of financial aspects in the process of pricing) are needed, trying to combine welfare and industrial policies.

The New Homelessness Revisited

Lee, Barrett A.; Tyler, Kimberly A.; Wright, James D.

2014-01-01

The ‘new homelessness’ has drawn sustained attention from scholars over the past three decades. Definitional inconsistencies and data limitations rendered early work during this period largely speculative in nature. Thanks to conceptual, theoretical, and methodological progress, however, the research literature now provides a fuller understanding of homelessness. Contributions by sociologists and other social scientists since the mid-1990s differentiate among types of homelessness, provide credible demographic estimates, and show how being homeless affects a person's life chances and coping strategies. Agreement also exists about the main macro- and micro-level causes of homelessness. Active lines of inquiry examine public, media, and governmental responses to the problem as well as homeless people's efforts to mobilize on their own behalf. Despite the obstacles faced when studying a stigmatized population marked by high turnover and weak anchors to place, recent investigations have significantly influenced homelessness policy. A greater emphasis on prevention should further strengthen the research-policy nexus. PMID:24910495

The Complex Relationship Between Diet And Health.

The relationship between food and health is complex. Everyone needs food to live, but too little food, too much food, or the wrong type of food has negative consequences for health. To increase understanding of this relationship, we describe trends and patterns in food-related diseases among both adults and children. Using an ecological framework, we then describe why food intake is complex with a discussion of three broad levels--macro (including policy and social-cultural norms), local community, and individual environments--and their relationship to food consumption. Given the strong relationship between an individual's food choice and his or her surrounding environment, we end with examples of policy responses that aim to help people overcome environmental disincentives toward healthy eating. Finding ways to make eating healthfully easier and affordable for all populations is essential to shifting the average American diet toward one that promotes health.

The Delicate Analysis of Short-Term Load Forecasting

NASA Astrophysics Data System (ADS)

Song, Changwei; Zheng, Yuan

2017-05-01

This paper proposes a new method for short-term load forecasting based on the similar day method, correlation coefficient and Fast Fourier Transform (FFT) to achieve the precision analysis of load variation from three aspects (typical day, correlation coefficient, spectral analysis) and three dimensions (time dimension, industry dimensions, the main factors influencing the load characteristic such as national policies, regional economic, holidays, electricity and so on). First, the branch algorithm one-class-SVM is adopted to selection the typical day. Second, correlation coefficient method is used to obtain the direction and strength of the linear relationship between two random variables, which can reflect the influence caused by the customer macro policy and the scale of production to the electricity price. Third, Fourier transform residual error correction model is proposed to reflect the nature of load extracting from the residual error. Finally, simulation result indicates the validity and engineering practicability of the proposed method.

Right and access to healthcare for undocumented children: addressing the gap between international conventions and disparate implementations in North America and Europe.

Limited access to healthcare for vulnerable immigrant children in Europe and North America is increasingly worrisome as immigration policies harden. This paper analyzes the gap between States' obligations under international human rights law and the disparate local implementations in diverse countries. Studies that are both multidisciplinary and incorporate micro and macro level indicators are needed to reveal discrepancies between entitlements and access. It is argued that the lack of available data on the magnitude of the problem and on its individual and public health consequences stems from the conflicting situation faced by health institutions required to simultaneously protect the best interest of each child and allocate limited resources. Collaboration in research is urgently needed to assist policy-makers and institutions make informed decisions. Copyright 2009 Elsevier Ltd. All rights reserved.

Long-working-distance fluorescence microscope with high-numerical-aperture objectives for variable-magnification imaging in live mice from macro- to subcellular

We demonstrate the development of a long-working-distance fluorescence microscope with high-numerical-aperture objectives for variable-magnification imaging in live mice from macro- to subcellular. To observe cytoplasmic and nuclear dynamics of cancer cells in the living mouse, 143B human osteosarcoma cells are labeled with green fluorescent protein in the nucleus and red fluorescent protein in the cytoplasm. These dual-color cells are injected by a vascular route in an abdominal skin flap in nude mice. The mice are then imaged with the Olympus MVX10 macroview fluorescence microscope. With the MVX10, the nuclear and cytoplasmic behavior of cancer cells trafficking in blood vessels of live mice is observed. We also image lung metastases in live mice from the macro- to the subcellular level by opening the chest wall and imaging the exposed lung in live mice. Injected splenocytes, expressing cyan fluorescent protein, could also be imaged on the lung of live mice. We demonstrate that the MVX10 microscope offers the possibility of full-range in vivo fluorescence imaging from macro- to subcellular and should enable widespread use of powerful imaging technologies enabled by genetic reporters and other fluorophores.

The effect of family policies and public health initiatives on breastfeeding initiation among 18 high-income countries: a qualitative comparative analysis research design.

PubMed

Lubold, Amanda Marie

2017-01-01

The objective of this study is to examine the effects of macro-level factors - welfare state policies and public health initiatives - on breastfeeding initiation among eighteen high-income countries. This study utilizes fuzzy-set Qualitative Comparative Analysis methods to examine the combinations of conditions leading to both high and low national breastfeeding initiation rates among eighteen high-income countries. The most common pathway leading to high breastfeeding initiation is the combination of conditions including a high percentage of women in parliament, a low national cesarean section rate, and either low family spending, high rates of maternity leave, or high rates of women working part-time. The most common pathway leading to low breastfeeding initiation includes the necessary condition of low national adherence to the Baby-Friendly Hospital Initiative. This research suggests that there is a connection between broad level welfare state polices, public health initiatives, and breastfeeding initiation. Compliance with the WHO/UNICEF initiatives depends on welfare regime policies and overall support for women in both productive and reproductive labor.

Rethinking health research capacity strengthening

Health research capacity strengthening (HRCS) is a strategy implemented worldwide to improve the ability of developing countries to tackle the persistent and disproportionate burdens of disease they face. Drawing on a review of existing HRCS literature and our experiences over the course of an NIH-funded HRCS project in Vietnam, we summarise major challenges to the HRCS enterprise at the interpersonal, institutional and macro levels. While over the course of several decades of HRCS initiatives many of these challenges have been well documented, we highlight several considerations that remain under-articulated. We advance critical considerations of the HRCS enterprise by discussing 1) how the organisation of US public health funding shapes the ecology of knowledge production in low- and middle-income country contexts, 2) the barriers US researchers face to effectively collaborating in capacity strengthening for research-to-policy translation, and 3) the potential for unintentional negative consequences if HRCS efforts are not sufficiently reflexive about the limitations of dominant paradigms in public health research and intervention.

Tracing health system challenges in post-conflict Côte d'Ivoire from 1893 to 2013.

Gaber, Sabrina; Patel, Preeti

While scholarship on health in conflict-affected countries is growing, there has been relatively little analysis of how armed conflict affects health systems in specific African countries, especially former French colonies. There is even less literature on the role of history in shaping health systems and how historical factors such as inequity may influence health impacts of armed conflict. Based on Côte d'Ivoire, this article argues that historical multidisciplinary analysis can provide valuable insight into the macro-level political, economic and social determinants of the health system over time. It explores how armed conflict has affected health services and exacerbates historically inherited challenges to the health system including unequal distribution of health services, bias towards curative care in urban areas, inadequate human resources and weak health governance. In the post-conflict period, this understanding may assist governments and other stakeholders to develop more appropriate health policies that address both urgent and long-term health needs.

Three ion-exchange materials and one hydrophobic-interaction chromatography packing, based on a rigid macroporous polymer with large, relatively uniform pores, have been evaluated for low-pressure liquid chromatography of antibodies. These sorbents have high capacities for both small and large proteins and are mechanically, chemically, and thermally stable. Macro-Prep 50 S. CM and Q ion-exchange materials are strongly acidic, weakly acidic, and strongly basic, respectively. Protein binding and recovery, pressure-flow properties, and chemical and thermal stability were determined for each sorbent. A rapid, two-step method for the purification of anti-Klenow antibodies from goat serum was developed, based on the Macro-Prep 50 S strong-acid cation-exchange material and the Econo-Pac HIC prepacked hydrophobic-interaction cartridge.

Mediation analysis is a useful and widely employed approach to studies in the field of psychology and in the social and biomedical sciences. The contributions of this paper are several-fold. First we seek to bring the developments in mediation analysis for non linear models within the counterfactual framework to the psychology audience in an accessible format and compare the sorts of inferences about mediation that are possible in the presence of exposure-mediator interaction when using a counterfactual versus the standard statistical approach. Second, the work by VanderWeele and Vansteelandt (2009, 2010) is extended here to allow for dichotomous mediators and count outcomes. Third, we provide SAS and SPSS macros to implement all of these mediation analysis techniques automatically and we compare the types of inferences about mediation that are allowed by a variety of software macros.

2014-01-01

This study developed a macro-sized polyamide (PA) fiber for concrete reinforcement and investigated the influence of the PA fiber on flexural responses in accordance with ASTM standards. PA fibers are advantageous compared to steel fibers that are corrosive and gravitated. The macro-sized PA fiber significantly improved concrete ductility and toughness. Unlike steel fibers, the PA fibers produced two peak bending strengths. The first-peaks occurred near 0.005 mm of deflection and decreased up to 0.5 mm of deflection. Then the bending strength increased up to second-peaks until the deflections reached between 1.0 and 1.5 mm. The averaged flexural responses revealed that PA fiber content did not significantly influence flexural responses before L/600, but had significant influence thereafter. Toughness performance levels were also determined, and the results indicated more than Level II at L/600 and Level IV at others. PMID:28788265

The processing of textile to achieve a particular handle is one of the most important aspects of finishing technology. Fabrics softeners are liquid composition added to washing machines during the rinse cycle to make clothes feel better to the touch. The first fabric softeners were developed by the textile industry during the early twentieth century. In this research polyester fabrics were treated with nano, micro and macro emulsion silicone softeners. Some of the physical properties of the treated fabric samples are discussed. The drapeability of treated samples was improved after treatment with nano silicone softeners. The colorimetric measurement of softener-treated fabrics is evaluated with a reflectance spectrophotometer. Moisture regain of treated samples is increased due to coating of silicone softeners. There is some increase in the weight of softener-treated samples. Samples treated with nano emulsion silicones gave better results compared to micro- and macro-emulsion treated ones.

Over the last few years the application of thermal energy storage system incorporating phase change materials (PCMs) to foster productivity and efficiency of buildings energy has grown rapidly. In this study, a structural-functional integrated concrete was developed using macro-encapsulated PCM-lightweight aggregate (LWA) as partial replacement (25 and 50% by volume) of coarse aggregate in control concrete. The PCM-LWA was prepared by incorporation of an inorganic PCM into porous LWAs through vacuum impregnation. The mechanical and thermal performance of PCM-LWA concrete were studied. The test results revealed that though the compressive strength of concrete with PCM-LWA was lower than the control concrete, but ranged from 22.02 MPa to 42.88 MPa which above the minimum strength requirement for structural application. The thermal performance test indicated that macro-encapsulated PCM-LWA has underwent the phase change transition reducing the indoor temperature.

Quantifying the impact of legal culture and institution on carbon emissions

Anthropogenic carbon emissions has been believed to trigger more than half of the global warming over the past half a century. Climate change analysis based on human activities should not neglect the driving force of human society. Different countries or regions have different legal culture traditions and legal systems that can greatly influence regional carbon emissions. This will lead to differences in implementation way and implementation intensity of the law and policies. Without understanding the social and legal background, it is not enough to understand how the climate change rules work and what the effects enforce. Using the panel data of 71 countries from 1996-2010, this study analyzes the effects of macro channels influencing mitigation policies, which contains rules and regulations including value, religion, genealogy of law, public participation, regulatory, government effectiveness, corruption, rule of law, etc. The results show that the interaction between legal variables and economic variables is very important for carbon emissions reduction. The law affects the carbon emissions by adjusting the economic and other related variables, and vice verse, economic and other variables will also impact the level of the rule of law. The study also reveals that developing national economy is most countries' urgent current task, and there are not sound strategies or strong enforcement to guarantee the achievement of the emissions reduction commitment. It is not enough to make justice dominant by cultivating a fair attitude. Practical measures and institutional means for social justice must be promoted. These results will give insight to policy makers in creating feasible and practical climate polices.

Macro- and micro-designed chitosan-alginate scaffold architecture by three-dimensional printing and directional freezing.

While many tissue-engineered constructs aim to treat cartilage defects, most involve chondrocyte or stem cell seeding on scaffolds. The clinical application of cell-based techniques is limited due to the cost of maintaining cellular constructs on the shelf, potential immune response to allogeneic cell lines, and autologous chondrocyte sources requiring biopsy from already diseased or injured, scarce tissue. An acellular scaffold that can induce endogenous influx and homogeneous distribution of native stem cells from bone marrow holds great promise for cartilage regeneration. This study aims to develop such an acellular scaffold using designed, channeled architecture that simultaneously models the native zones of articular cartilage and subchondral bone. Highly porous, hydrophilic chitosan-alginate (Ch-Al) scaffolds were fabricated in three-dimensionally printed (3DP) molds designed to create millimeter scale macro-channels. Different polymer preform casting techniques were employed to produce scaffolds from both negative and positive 3DP molds. Macro-channeled scaffolds improved cell suspension distribution and uptake overly randomly porous scaffolds, with a wicking volumetric flow rate of 445.6 ± 30.3 mm(3) s(-1) for aqueous solutions and 177 ± 16 mm(3) s(-1) for blood. Additionally, directional freezing was applied to Ch-Al scaffolds, resulting in lamellar pores measuring 300 μm and 50 μm on the long and short axes, thus creating micrometer scale micro-channels. After directionally freezing Ch-Al solution cast in 3DP molds, the combined macro- and micro-channeled scaffold architecture enhanced cell suspension uptake beyond either macro- or micro-channels alone, reaching a volumetric flow rate of 1782.1 ± 48 mm(3) s(-1) for aqueous solutions and 440.9 ± 0.5 mm(3) s(-1) for blood. By combining 3DP and directional freezing, we can control the micro- and macro-architecture of Ch-Al to drastically improve cell influx into and distribution within the scaffold, while achieving porous zones that mimic articular cartilage zonal architecture. In future applications, precisely controlled micro- and macro-channels have the potential to assist immediate endogenous bone marrow uptake, stimulate chondrogenesis, and encourage vascularization of bone in an osteochondral scaffold.

Application of noninvasive optical coherent-domain methods and advanced data processing tools such as the wavelet-based multifractal formalism allows revealing effective markers of early stages of functional distortions in the dynamics of cerebral vessels. Based on experiments performed in rats we discuss a possibility to diagnose a hidden stage of the development of intracranial hemorrhage (ICH). We also consider responses of the cerebrovascular dynamics to a pharmacologically induced increase in the peripheral blood pressure. We report distinctions occurring at the levels of macro- and microcerebral circulation.

Evolution is a cornerstone theory in biology, yet many undergraduate students have difficulty understanding it. One reason for this is that evolution is often taught in a macro-scale context without explicit links to micro-scale processes. To address this, we developed a series of integrative evolution cases that present the evolution of various traits from their origin in genetic mutation, to the synthesis of modified proteins, to how these proteins produce novel phenotypes, to the related macro-scale impacts that the novel phenotypes have on populations in ecological communities. We postulated that students would develop a fuller understanding of evolution when learning biology in a context where these integrative evolution cases are used. We used a previously developed assessment tool, the ATEEK (Assessment Tool for Evaluating Evolution Knowledge), within a pre-course/post-course assessment framework. Students who learned biology in courses using the integrative cases performed significantly better on the evolution assessment than did students in courses that did not use the cases. We also found that student understanding of evolution increased with increased exposure to the integrative evolution cases. These findings support the general hypothesis that students acquire a more complete understanding of evolution when they learn about its genetic and molecular mechanisms along with macro-scale explanations.

Under-nutrition in older adults is widespread. Oral nutritional supplement beverages (ONS) are prescribed, yet consumption by older people is often insufficient. A variety of supplement formats may improve nutrient intake. This study developed protein and micro-nutrient fortified biscuits and evaluated their sensory attributes and liking by older people. Two micro-nutrient strategies were taken, to match typical ONS and to customise to the needs of older people. Oat biscuits and gluten-free biscuits developed contained over 12% protein and over 460 kcal 100 g(-1). Two small (40 g) biscuits developed to match ONS provided approximately 40% of an ONS portion of micro-nutrients and 60% of macro-nutrients; however, the portion size was considered realistic whereas the average ONS portion (200 mL) is excessive. Biscuits developed to the needs of older adults provided, on average, 18% of the reference nutrient intake of targeted micro-nutrients. Sensory characteristics were similar between biscuits with and without micro-nutrient fortification, leading to no differences in liking. Fortified oat biscuits were less liked than commercial oat biscuits, partly attributed to flavour imparted by whey protein fortification. Macro- and micro-nutrient fortification of biscuits could provide an alternative fortified snack to help alleviate malnutrition in older adults. © 2013 Society of Chemical Industry.

Informing Ex Ante Event Studies with Macro-Econometric Evidence on the Structural and Policy Impacts of Terrorism.

PubMed

Nassios, Jason; Giesecke, James A

2018-04-01

Economic consequence analysis is one of many inputs to terrorism contingency planning. Computable general equilibrium (CGE) models are being used more frequently in these analyses, in part because of their capacity to accommodate high levels of event-specific detail. In modeling the potential economic effects of a hypothetical terrorist event, two broad sets of shocks are required: (1) physical impacts on observable variables (e.g., asset damage); (2) behavioral impacts on unobservable variables (e.g., investor uncertainty). Assembling shocks describing the physical impacts of a terrorist incident is relatively straightforward, since estimates are either readily available or plausibly inferred. However, assembling shocks describing behavioral impacts is more difficult. Values for behavioral variables (e.g., required rates of return) are typically inferred or estimated by indirect means. Generally, this has been achieved via reference to extraneous literature or ex ante surveys. This article explores a new method. We elucidate the magnitude of CGE-relevant structural shifts implicit in econometric evidence on terrorist incidents, with a view to informing future ex ante event assessments. Ex post econometric studies of terrorism by Blomberg et al. yield macro econometric equations that describe the response of observable economic variables (e.g., GDP growth) to terrorist incidents. We use these equations to determine estimates for relevant (unobservable) structural and policy variables impacted by terrorist incidents, using a CGE model of the United States. This allows us to: (i) compare values for these shifts with input assumptions in earlier ex ante CGE studies; and (ii) discuss how future ex ante studies can be informed by our analysis. © 2017 Society for Risk Analysis.

When Corporate Social Responsibility (CSR) Meets Organizational Psychology: New Frontiers in Micro-CSR Research, and Fulfilling a Quid Pro Quo through Multilevel Insights

Researchers, corporate leaders, and other stakeholders have shown increasing interest in Corporate Social Responsibility (CSR)—a company’s discretionary actions and policies that appear to advance societal well-being beyond its immediate financial interests and legal requirements. Spanning decades of research activity, the scholarly literature on CSR has been dominated by meso- and macro-level perspectives, such as studies within corporate strategy that examine relationships between firm-level indicators of social/environmental performance and corporate financial performance. In recent years, however, there has been an explosion of micro-oriented CSR research conducted at the individual level of analysis, especially with respect to studies on how and why job seekers and employees perceive and react to CSR practices. This micro-level focus is reflected in 12 articles published as a Research Topic collection in Frontiers in Psychology (Organizational Psychology Specialty Section) titled “CSR and organizational psychology: Quid pro quo.” In the present article, the authors summarize and integrate findings from these Research Topic articles. After describing some of the “new frontiers” these articles explore and create, the authors strive to fulfill a “quid pro quo” with some of the meso- and macro-oriented CSR literatures that paved the way for micro-CSR research. Specifically, the authors draw on insights from the Research Topic articles to inform a multilevel model that offers multiple illustrations of how micro-level processes among individual stakeholders can explain variability in meso (firm)-level relationships between CSR practices and corporate performance. The authors also explore an important implication of these multilevel processes for macro-level societal impact. PMID:28439247

In recent years, however, there has been an explosion of micro-oriented CSR research conducted at the individual level of analysis, especially with respect to studies on how and why job seekers and employees perceive and react to CSR practices. This micro-level focus is reflected in 12 articles published as a Research Topic collection in Frontiers in Psychology (Organizational Psychology Specialty Section) titled "CSR and organizational psychology: Quid pro quo." In the present article, the authors summarize and integrate findings from these Research Topic articles. After describing some of the "new frontiers" these articles explore and create, the authors strive to fulfill a "quid pro quo" with some of the meso- and macro-oriented CSR literatures that paved the way for micro-CSR research. Specifically, the authors draw on insights from the Research Topic articles to inform a multilevel model that offers multiple illustrations of how micro-level processes among individual stakeholders can explain variability in meso (firm)-level relationships between CSR practices and corporate performance. The authors also explore an important implication of these multilevel processes for macro-level societal impact.

The macros were designed for use with Macintosh computers but will also run with the DOS version of Excel.

The Commercial Energy Consumer: About Whom Are We Speaking?

DOE Office of Scientific and Technical Information (OSTI.GOV)

Payne, Christopher

2006-05-12

Who are commercial sector customers, and how do they make decisions about energy consumption and energy efficiency investment? The energy policy field has not done a thorough job of describing energy consumption in the commercial sector. First, the discussion of the commercial sector itself is dominated by discussion of large businesses/buildings. Second, discussion of this portion of the commercial sectors consumption behavior is driven primarily by theory, with very little field data collected on the way commercial sector decision-makers describe their own options, choices, and reasons for taking action. These limitations artificially constrain energy policy options. This paper reviews themore » extant literature on commercial sector energy consumption behavior and identifies gaps in our knowledge. In particular, it argues that the primary energy policy model of commercial sector energy consumption is a top-down model that uses macro-level investment data to make conclusions about commercial behavior. Missing from the discussion is a model of consumption behavior that builds up to a theoretical framework informed by the micro-level data provided by commercial decision-makers themselves. Such a bottom-up model could enhance the effectiveness of commercial sector energy policy. In particular, translation of some behavioral models from the residential sector to the commercial sector may offer new opportunities for policies to change commercial energy consumption behavior. Utility bill consumption feedback is considered as one example of a policy option that may be applicable to both the residential and small commercial sector.« less

Studying neighborhood crime across different macro spatial scales: The case of robbery in 4 cities.

PubMed

Hipp, John R; Wo, James C; Kim, Young-An

2017-11-01

Whereas there is a burgeoning literature focusing on the spatial distribution of crime events across neighborhoods or micro-geographic units in a specific city, the present study expands this line of research by selecting four cities that vary across two macro-spatial dimensions: population in the micro-environment, and population in the broader macro-environment. We assess the relationship between measures constructed at different spatial scales and robbery rates in blocks in four cities: 1) San Francisco (high in micro- and macro-environment population); 2) Honolulu (high in micro- but low in macro-environment population); 3) Los Angeles (low in micro- but high in macro-environment population); 4) Sacramento (low in micro- and macro-environment population). Whereas the socio-demographic characteristics of residents further than ½ mile away do not impact robbery rates, the number of people up to 2.5 miles away are related to robbery rates, especially in the two cities with smaller micro-environment population, implying a larger spatial scale than is often considered. The results show that coefficient estimates differ somewhat more between cities differing in micro-environment population compared to those differing based on macro-environment population. It is therefore necessary to consider the broader macro-environment even when focusing on the level of crime across neighborhoods or micro-geographic units within an area.

Adaptive macro finite elements for the numerical solution of monodomain equations in cardiac electrophysiology.

PubMed

Heidenreich, Elvio A; Ferrero, José M; Doblaré, Manuel; Rodríguez, José F

2010-07-01

Many problems in biology and engineering are governed by anisotropic reaction-diffusion equations with a very rapidly varying reaction term. This usually implies the use of very fine meshes and small time steps in order to accurately capture the propagating wave while avoiding the appearance of spurious oscillations in the wave front. This work develops a family of macro finite elements amenable for solving anisotropic reaction-diffusion equations with stiff reactive terms. The developed elements are incorporated on a semi-implicit algorithm based on operator splitting that includes adaptive time stepping for handling the stiff reactive term. A linear system is solved on each time step to update the transmembrane potential, whereas the remaining ordinary differential equations are solved uncoupled. The method allows solving the linear system on a coarser mesh thanks to the static condensation of the internal degrees of freedom (DOF) of the macroelements while maintaining the accuracy of the finer mesh. The method and algorithm have been implemented in parallel. The accuracy of the method has been tested on two- and three-dimensional examples demonstrating excellent behavior when compared to standard linear elements. The better performance and scalability of different macro finite elements against standard finite elements have been demonstrated in the simulation of a human heart and a heterogeneous two-dimensional problem with reentrant activity. Results have shown a reduction of up to four times in computational cost for the macro finite elements with respect to equivalent (same number of DOF) standard linear finite elements as well as good scalability properties.

The use of a macromolecular RAFT (macro-RAFT) agent to encapsulate anisotropic nano-objects via emulsion polymerization is an emerging route to prepare polymer/inorganic colloidal nanocomposites. However, a number of requirements have to be fulfilled. This work aims at highlighting the effects of the preparative procedure and dispersion method on the amount of macro-RAFT agent adsorbed onto SiO2-coated Gd2O3:Eu3+ nanorods. The adsorption of macro-RAFT agent was studied using the depletion method with UV-vis spectrophotometry. Measurements were performed at a fixed concentration of nanorods and varying concentrations of the macro-RAFT agent in aqueous dispersion at room temperature. The adsorption isotherms showed that for the same initial macro-RAFT agent concentration, the highest adsorption capacity of the macro-RAFT agent on nanorods was usually achieved for non-calcined thin SiO2-coated nanorods under mild bath sonication.

Constraints and changes in the development of science and technology policies in Argentina's University of Buenos Aires and the National Autonomous University of Mexico

1999-06-01

This dissertation is a comparison of the effects of structural adjustment on scientific and technological policies in two of the largest and most important universities of Latin America, UBA and UNAM. In its broadest sense, scientific and technological policies encompass a set of interventions, decisions, and activities of different institutions within a given society aimed to hinder or stimulate the progress of scientific research, and the application of its products to socioeconomic, political, cultural or military objectives. The methodological approach for this dissertation aimed to combine data collected at both the macro and micro levels. First, a profound examination of different bibliographical sources such as books, articles, and documents of different kinds (policy papers, national plans, and working papers), was carried out. Secondly, a series of interviews were conducted with scientists in some of the natural sciences' research centers and institutes, academic administrators and top officials of the S&T government agencies, in Argentina and Mexico, The main goal of these interviews was to understand the institutional dynamics as it was shaped by actors and processes, outside and within the two universities. This study found that the structural adjustment process in Argentina and Mexico has negatively affected the S&T policies in both UBA and UNAM. Local S&T played a original role in the two universities under scrutiny. Investments in science and technology have remained significantly low in Argentina and Mexico. In addition to this, the small amount of scientific personnel, the predominantly public characteristic of S&T funds, and the reduced number of doctoral graduates resulted in low levels of scientific output as compared with the number of publications in international scientific literature. A predominant academic orientation with few contributions to societal needs, either related to the productive sectors or to social problems such as pollution, energy, food, and health, among others, was also seen. A coherent and articulated S&T policy linking the university, the state, and the productive sectors, could only be achieved if it is included in a different economic strategy that would go beyond the limitations of the neoliberal model.

Filtered cathodic arc deposition apparatus and method

DOEpatents

Krauss, Alan R.

1999-01-01

A filtered cathodic arc deposition method and apparatus for the production of highly dense, wear resistant coatings which are free from macro particles. The filtered cathodic arc deposition apparatus includes a cross shaped vacuum chamber which houses a cathode target having an evaporable surface comprised of the coating material, means for generating a stream of plasma, means for generating a transverse magnetic field, and a macro particle deflector. The transverse magnetic field bends the generated stream of plasma in the direction of a substrate. Macro particles are effectively filtered from the stream of plasma by traveling, unaffected by the transverse magnetic field, along the initial path of the plasma stream to a macro particle deflector. The macro particle deflector has a preformed surface which deflects macro particles away from the substrate.

A New Dual-Pore Formation Factor Model: A Percolation Network Study and Comparison to Experimental Data

NASA Astrophysics Data System (ADS)

Tang, Y. B.; Li, M.; Bernabe, Y.

2014-12-01

We modeled the electrical transport behavior of dual-pore carbonate rocks in this paper. Based on experimental data of a carbonate reservoir in China, we simply considered the low porosity samples equivalent to the matrix (micro-pore system) of the high porosity samples. For modeling the bimodal porous media, we considered that the matrix is homogeneous and interconnected. The connectivity and the pore size distribution of macro-pore system are varied randomly. Both pore systems are supposed to act electrically in parallel, connected at the nodes, where the fluid exchange takes place, an approach previously used by Bauer et al. (2012). Then, the effect of the properties of matrix, the pore size distribution and connectivity of macro-pore system on petrophysical properties of carbonates can be investigated. We simulated electrical current through networks in three-dimensional simple cubic (SC) and body-center cubic (BCC) with different coordination numbers and different pipe radius distributions of macro-pore system. Based on the simulation results, we found that the formation factor obeys a "universal" scaling relationship (i.e. independent of lattice type), 1/F∝eγz, where γ is a function of the normalized standard deviation of the pore radius distribution of macro-pore system and z is the coordination number of macro-pore system. This relationship is different from the classic "universal power law" in percolation theory. A formation factor model was inferred on the basis of the scaling relationship mentioned above and several scale-invariant quantities (such as hydraulic radius rH and throat length l of macro-pore). Several methods were developed to estimate corresponding parameters of the new model with conventional core analyses. It was satisfactorily tested against experimental data, including some published experimental data. Furthermore, the relationship between water saturation and resistivity in dual-pore carbonates was discussed based on the new model.

A multiscale framework based on the physiome markup languages for exploring the initiation of osteoarthritis at the bone-cartilage interface.

PubMed

Shim, Vickie B; Hunter, Peter J; Pivonka, Peter; Fernandez, Justin W

2011-12-01

The initiation of osteoarthritis (OA) has been linked to the onset and progression of pathologic mechanisms at the cartilage-bone interface. Most importantly, this degenerative disease involves cross-talk between the cartilage and subchondral bone environments, so an informative model should contain the complete complex. In order to evaluate this process, we have developed a multiscale model using the open-source ontologies developed for the Physiome Project with cartilage and bone descriptions at the cellular, micro, and macro levels. In this way, we can effectively model the influence of whole body loadings at the macro level and the influence of bone organization and architecture at the micro level, and have cell level processes that determine bone and cartilage remodeling. Cell information is then passed up the spatial scales to modify micro architecture and provide a macro spatial characterization of cartilage inflammation. We evaluate the framework by linking a common knee injury (anterior cruciate ligament deficiency) to proinflammatory mediators as a possible pathway to initiate OA. This framework provides a "virtual bone-cartilage" tool for evaluating hypotheses, treatment effects, and disease onset to inform and strengthen clinical studies.

Superconducting Transition-Edge Sensors (TESs) are generating a great deal of interest in the areas of x-ray astrophysics and space science, particularly to develop them as large-array, imaging x-ray spectrometers. We are developing a novel concept that is based on position-sensitive macro-pixels placing TESs on the backside of a silicon or germanium absorber. Each x-ray absorbed will be position (X/δX and Y/δY ~ 100) and energy (E/δE ~ 1000) resolved via four distributed TES readouts. In the future, combining such macropixels with advances in multiplexing could lead to 30 by 30 arrays of close-packed macro-pixels equivalent to imaging instruments of 10 megapixels or more. We report on our progress to date and discuss its application to a plausible solar satellite mission and plans for future development.

Modeling and deadlock avoidance of automated manufacturing systems with multiple automated guided vehicles.

PubMed

Wu, Naiqi; Zhou, MengChu

2005-12-01

An automated manufacturing system (AMS) contains a number of versatile machines (or workstations), buffers, an automated material handling system (MHS), and is computer-controlled. An effective and flexible alternative for implementing MHS is to use automated guided vehicle (AGV) system. The deadlock issue in AMS is very important in its operation and has extensively been studied. The deadlock problems were separately treated for parts in production and transportation and many techniques were developed for each problem. However, such treatment does not take the advantage of the flexibility offered by multiple AGVs. In general, it is intractable to obtain maximally permissive control policy for either problem. Instead, this paper investigates these two problems in an integrated way. First we model an AGV system and part processing processes by resource-oriented Petri nets, respectively. Then the two models are integrated by using macro transitions. Based on the combined model, a novel control policy for deadlock avoidance is proposed. It is shown to be maximally permissive with computational complexity of O (n2) where n is the number of machines in AMS if the complexity for controlling the part transportation by AGVs is not considered. Thus, the complexity of deadlock avoidance for the whole system is bounded by the complexity in controlling the AGV system. An illustrative example shows its application and power.

Learning from health system reforms: lessons from Burkina Faso.

Burkina Faso has implemented a macroeconomic adjustment programme (MAP) along with an ambitious reform of the health care system. Our aim was (1) to verify whether MAPs led to a reduction in health resources, and (2) to analyze the consequences of health policies implemented. Cross-sectional and retrospective study, spanning the years 1983-2003. The macro aspect is based upon documents from national and international sources, a database of secondary socioeconomic data, and interviews of key informants working in upper management. Household and health facility surveys were conducted in three regions covering 53 communities. Within the reforms, the health sector benefited from an important flow of resources. There were significant increases in public expenditures, health care staff, the number of primary care facilities and the availability of generic drugs. However, health facilities in the public sector remain underused and major inequities subsist. Access to health care is constrained by the population's ability to pay. Health expenditures impoverish households, creating new poor and impoverishing the already poor. The success of reforms depends largely on the extent to which they remove financial barriers to access to services. The experience of Burkina Faso also reveals the need for fundamental changes that will motivate staff, improve productivity, and ensure good quality services. Integrating health development policies with strategic plans for poverty reduction can provide new opportunities for African countries to redesign their health systems within this type of perspective.

We evaluated the nosocomial outbreak of Middle East Respiratory Syndrome (MERS) Coronavirus (CoV) in the Republic of Korea, 2015, from a healthcare operations management perspective. Establishment of healthcare policy in South Korea provides patients' freedom to select and visit multiple hospitals. Current policy enforces hospitals preference for multi-patient rooms to single-patient rooms, to lower financial burden. Existing healthcare systems tragically contributed to 186 MERS outbreak cases, starting from single "index patient" into three generations of secondary infections. By developing a macro-level health system dynamics model, we provide empirical knowledge to examining the case from both operational and financial perspectives. In our simulation, under base infectivity scenario, high emergency room occupancy circumstance contributed to an estimated average of 101 (917%) more infected patients, compared to when in low occupancy circumstance. Economic patient room design showed an estimated 702% increase in the number of infected patients, despite the overall 98% savings in total expected costs compared to optimal room design. This study provides first time, system dynamics model, performance measurements from an operational perspective. Importantly, the intent of this study was to provide evidence to motivate public, private, and government healthcare administrators' recognition of current shortcomings, to optimize performance as a whole system, rather than mere individual aspects.

Many changes have been initiated in the Dutch hospital sector to optimize health-care delivery: national agenda-setting, increased competition and transparency, a new system of hospital reimbursement based on diagnosis-treatment combinations, intensified monitoring of quality and a multi-layered organizational development programme based on quality improvement collaboratives. The objective is to answer the question as to whether these changes were accompanied by a further development of hospital quality management systems and to what extent did the development within the multi-layered programme hospitals differ from that in other hospitals. Longitudinal data were collected in 1995, 2000, 2005 and 2007 using a validated questionnaire. Descriptive analyses and multi-level modelling were applied to test whether: (1) quality management system development stages in hospitals differ over time, (2) development stages and trends differ between hospitals participating or not participating in the multi-layered programme and (3) hospital size has an effect on development stage. Dutch hospital sector between 1995 and 2007. Hospital organizations. Changes through time. Quality management system development stage. Since 1995, hospital quality management systems have reached higher development levels. Programme participants have developed their quality management system more rapidly than have non-participants. However, this effect is confounded by hospital size. Study results suggest that the combination of policy measures at macro level was accompanied by an increase in hospital size and the further development of quality management systems. Hospitals are entering the stage of systematic quality improvement.

Impacts of climate change in the sugarcane production in the center-south macro-region of Brazil

This paper describes the most important results of a Project developed over four years by a research network having 19 researchers and 45 students. The main objective of this Project was to generate alcohol production scenarios as support for the formulation of public policy applied to the adaptation of the Brazilian sugar and alcohol industry to the possible climate changes. The study area was the center-south macro-region of Brazil, with the states of São Paulo, Paraná, Minas Gerais, Mato Grosso do Sul and Goiás, that is the main producer area of sugarcane in the world. The scenarios were developed using the HadGEM2-ES and Miroc5 models of CMIP5/IPCC and did not show significant differences between them and were very close to those obtained with the HadCM3 and Miroc3 models of the AR4/IPCC. The results considering the sugarcane varieties grown nowadays indicate that in a scenario with changes in precipitation and temperatures, the main producing region will not have a decrease in municipalities with low climatic risk. Also the expansion region (South of Goiás and North-West of São Paulo) may become of high climatic risk, becoming an area where the artificial irrigation will be demanded. The challenge related to the water use and availability that already exists nowadays will be yet more important in the future. The expansion of Brazilian sugarcane production is being much more based on the territorial extension, i.e. by increasing the production area, than by increasing the productivity. The increased mechanization of cane harvesting improves the air quality and reduces the incidence of respiratory diseases. It is extremely important that incentives to mechanization be extended to other regions of the country since the end of burning benefits the health of people living close to the sugarcane fields. This confirms the need for planning this sector, with the development of new varieties and new production technologies considering the possible future climate conditions.

Linking micro- and macro-evolution at the cell type level: a view from the lophotrochozoan Platynereis dumerilii.

Simakov, Oleg; Larsson, Tomas A; Arendt, Detlev

2013-09-01

Ever since the origin of the first metazoans over 600 million years ago, cell type diversification has been driven by micro-evolutionary processes at population level, leading to macro-evolution changes above species level. In this review, we introduce the marine annelid Platynereis dumerilii, a member of the lophotrochozoan clade (a key yet most understudied superphylum of bilaterians), as a suitable model system for the simultaneous study, at cellular resolution, of macro-evolutionary processes across phyla and of micro-evolutionary processes across highly polymorphic populations collected worldwide. Recent advances in molecular and experimental techniques, easy maintenance and breeding, and the fast, synchronous and stereotypical development have facilitated the establishment of Platynereis as one of the leading model species in the eco-evo-devo field. Most importantly, Platynereis allows the combination of expression profiling, morphological and physiological characterization at the single cell level. Here, we discuss recent advances in the collection of -omics data for the lab strain and for natural populations collected world-wide that can be integrated with population-specific cellular analyses to result in a cellular atlas integrating genetic, phenotypic and ecological variation. This makes Platynereis a tractable system to begin understanding the interplay between macro- and micro-evolutionary processes and cell type diversity.

Innovation evaluation model for macro-construction sector companies: A study in Spain.

2017-04-01

The innovativeness of the traditional construction sector, composed of construction companies or contractors, is not one of its strong points. Likewise, its poor productivity in comparison with other sectors, such as manufacturing, has historically been criticized. Similar features are found in the Spanish traditional construction sector, which it has been described as not very innovative. However, certain characteristics of the sector may explain this behavior; the companies invest in R+D less than in other sectors and release fewer patents, so traditional innovation evaluation indicators do not reflect the true extent of its innovative activity. While previous research has focused on general innovation evaluation models, limited research has been done regarding innovation evaluation in the macro-construction sector, which includes, apart from the traditional construction companies or contractors, all companies related to the infrastructure life-cycle. Therefore, in this research an innovation evaluation model has been developed for macro-construction sector companies and is applied in the Spanish case. The model may be applied to the macro-construction sector companies in other countries, requiring the adaption of the model to the specific characteristics of the sector in that country, in consultation with a panel of experts at a national level.

The Molecular Analyzer for Complex Refractory Organic-rich Surfaces, MACROS, is a novel instrument package being developed at NASA Goddard Space Flight Center. MACROS enables the in situ characterization of a sample's composition by coupling two powerful techniques into one compact instrument package: (1) laser desorption/ionization time-of-flight mass spectrometry (LDMS) for broad detection of inorganic mineral composition and non-volatile organics, and (2) liquid-phase extraction methods to gently isolate the soluble organic and inorganic fraction of a planetary powder for enrichment and detailed analysis by liquid chromatographic separation coupled to LDMS. The LDMS is capable of positive and negative ion detection, precision mass selection, and fragment analysis. Two modes are included for LDMS: single laser LDMS as the broad survey mode and two step laser mass spectrometry (L2MS). The liquid-phase extraction will be done in a newly designed extraction module (EM) prototype, providing selectivity in the analysis of a complex sample. For the sample collection, a diamond drill front end will be used to collect rock/icy powder. With all these components and capabilities together, MACROS offers a versatile analytical instrument for a mission targeting an icy moon, carbonaceous asteroid, or comet, to fully characterize the surface composition and advance our understanding of the chemical inventory present on that body.

The complete macro- and microequilibrium analyses of six fluoroquinolone drugs - ciprofloxacin, enrofloxacin, norfloxacin, pefloxacin, ofloxacin and moxifloxacin - are presented. Previous controversial literature data are straightened up, the protonation centers are unambiguously identified, and the protonation macro- and microconstant values are reported. The macroconstants were determined by (1)H NMR-pH titrations while the microconstants were determined by a multi-modal spectroscopic-deductive methodology, in which methyl ester derivatives were synthesized and their NMR-pH titration data contributed to the evaluation of all the microconstants. The full (1)H, (13)C and (15)N NMR assignments, NMR-pH profiles, macro- and microprotonation schemes and species-specific diagrams are included. Our studies show that the fluoroquinolones have three protonation centers: the carboxylate group, the N-1' and N-4' piperazine nitrogens and concentration of the uncharged microspecies is way below the values published earlier. The results could be well interpreted in terms of structural properties. The protonation macro- and microconstant values allow the pre-planned method development in techniques such as capillary zone electrophoresis and also, the interpretation of fluoroquinolone mechanism of biological action, including the pharmacokinetic properties, and antibacterial activities that are all heavily influenced by the states of protonation.

The role of economic evaluation in the decision-making process of family physicians: design and methods of a qualitative embedded multiple-case study

PubMed Central

Lessard, Chantale; Contandriopoulos, André-Pierre; Beaulieu, Marie-Dominique

2009-01-01

Background A considerable amount of resource allocation decisions take place daily at the point of the clinical encounter; especially in primary care, where 80 percent of health problems are managed. Ignoring economic evaluation evidence in individual clinical decision-making may have a broad impact on the efficiency of health services. To date, almost all studies on the use of economic evaluation in decision-making used a quantitative approach, and few investigated decision-making at the clinical level. An important question is whether economic evaluations affect clinical practice. The project is an intervention research study designed to understand the role of economic evaluation in the decision-making process of family physicians (FPs). The contributions of the project will be from the perspective of Pierre Bourdieu's sociological theory. Methods/design A qualitative research strategy is proposed. We will conduct an embedded multiple-case study design. Ten case studies will be performed. The FPs will be the unit of analysis. The sampling strategies will be directed towards theoretical generalization. The 10 selected cases will be intended to reflect a diversity of FPs. There will be two embedded units of analysis: FPs (micro-level of analysis) and field of family medicine (macro-level of analysis). The division of the determinants of practice/behaviour into two groups, corresponding to the macro-structural level and the micro-individual level, is the basis for Bourdieu's mode of analysis. The sources of data collection for the micro-level analysis will be 10 life history interviews with FPs, documents and observational evidence. The sources of data collection for the macro-level analysis will be documents and 9 open-ended, focused interviews with key informants from medical associations and academic institutions. The analytic induction approach to data analysis will be used. A list of codes will be generated based on both the original framework and new themes introduced by the participants. We will conduct within-case and cross-case analyses of the data. Discussion The question of the role of economic evaluation in FPs' decision-making is of great interest to scientists, health care practitioners, managers and policy-makers, as well as to consultants, industry, and society. It is believed that the proposed research approach will make an original contribution to the development of knowledge, both empirical and theoretical. PMID:19210787

Differences in stroke care and outcomes reported in Europe may reflect different degrees of implementation of evidence-based interventions. We evaluated strategies for implementing research evidence into stroke care in 10 European countries. A questionnaire was developed and administered through face-to-face interviews with key informants. Implementation strategies were investigated considering 3 levels (macro, meso, and micro, eg, policy, organization, patients/professionals) identified by the framing analysis, and different settings (primary, hospital, and specialist) of stroke care. Similarities and differences among countries were evaluated using the categorical principal components analysis. Implementation methods reported by ≥7 countries included nonmandatory policies, public financial incentives, continuing professional education, distribution of educational material, educational meetings and campaigns, guidelines, opinion leaders', and stroke patients associations' activities. Audits were present in 6 countries at national level; national and regional regulations in 4 countries. Private financial incentives, reminders, and educational outreach visits were reported only in 2 countries. At national level, the first principal component of categorical principal components analysis separated England, France, Scotland, and Sweden, all with positive object scores, from the other countries. Belgium and Lithuania obtained the lowest scores. At regional level, England, France, Germany, Italy, and Sweden had positive scores in the first principal component, whereas Belgium, Lithuania, Poland, and Scotland showed negative scores. Spain was in an intermediate position. We developed a novel method to assess different domains of implementation in stroke care. Clear variations were observed among European countries. The new tool may be used elsewhere for future contributions. © 2015 American Heart Association, Inc.

Causal interactions within complex systems can be analyzed at multiple spatial and temporal scales. For example, the brain can be analyzed at the level of neurons, neuronal groups, and areas, over tens, hundreds, or thousands of milliseconds. It is widely assumed that, once a micro level is fixed, macro levels are fixed too, a relation called supervenience. It is also assumed that, although macro descriptions may be convenient, only the micro level is causally complete, because it includes every detail, thus leaving no room for causation at the macro level. However, this assumption can only be evaluated under a proper measure of causation. Here, we use a measure [effective information (EI)] that depends on both the effectiveness of a system's mechanisms and the size of its state space: EI is higher the more the mechanisms constrain the system's possible past and future states. By measuring EI at micro and macro levels in simple systems whose micro mechanisms are fixed, we show that for certain causal architectures EI can peak at a macro level in space and/or time. This happens when coarse-grained macro mechanisms are more effective (more deterministic and/or less degenerate) than the underlying micro mechanisms, to an extent that overcomes the smaller state space. Thus, although the macro level supervenes upon the micro, it can supersede it causally, leading to genuine causal emergence--the gain in EI when moving from a micro to a macro level of analysis.

Inside the Mechanics of Network Development: How Competition and Strategy Reorganize European Air Traffic

Huber, Hans

2006-01-01

Air transport forms complex networks that can be measured in order to understand its structural characteristics and functional properties. Recent models for network growth (i.e., preferential attachment, etc.) remain stochastic and do not seek to understand other network-specific mechanisms that may account for their development in a more microscopic way. Air traffic is made up of many constituent airlines that are either privately or publicly owned and that operate their own networks. They follow more or less similar business policies each. The way these airline networks organize among themselves into distinct traffic distributions reveals complex interaction among them, which in turn can be aggregated into larger (macro-) traffic distributions. Our approach allows for a more deterministic methodology that will assess the impact of airline strategies on the distinct distributions for air traffic, particularly inside Europe. One key question this paper is seeking to answer is whether there are distinct patterns of preferential attachment for given classes of airline networks to distinct types of European airports. Conclusions about the advancing degree of concentration in this industry and the airline operators that accelerate this process can be drawn.

Ways of thinking about and teaching ethical problem solving: microethics and macroethics in engineering.

PubMed

Herkert, Joseph R

2005-07-01

Engineering ethics entails three frames of reference: individual, professional, and social. "Microethics" considers individuals and internal relations of the engineering profession; "macroethics" applies to the collective social responsibility of the profession and to societal decisions about technology. Most research and teaching in engineering ethics, including online resources, has had a "micro" focus. Mechanisms for incorporating macroethical perspectives include: integrating engineering ethics and science, technology and society (STS); closer integration of engineering ethics and computer ethics; and consideration of the influence of professional engineering societies and corporate social responsibility programs on ethical engineering practice. Integrating macroethical issues and concerns in engineering ethics involves broadening the context of ethical problem solving. This in turn implies: developing courses emphasizing both micro and macro perspectives, providing faculty development that includes training in both STS and practical ethics; and revision of curriculum materials, including online resources. Multidisciplinary collaboration is recommended 1) to create online case studies emphasizing ethical decision making in individual, professional, and societal contexts; 2) to leverage existing online computer ethics resources with relevance to engineering education and practice; and 3) to create transparent linkages between public policy positions advocated by professional societies and codes of ethics.

University community partnerships that promote evidence-based macro practice.

Mulroy, Elizabeth A

2008-01-01

This article articulates three dimensions of EBP grounded in theory for macro practice: intention toward social change, planning and decision-making, and civic participation. These dimensions are then applied to university community partnerships that are complex community interventions. The goals of these partnerships are to improve the social environment in low-income neighborhoods through community development and reform the university as a social institution from neighborhood bystander to responsible, engaged citizen. Finally, the article introduces the concept of a planning triangle, a framework linking evidence derived from community assessments and practice-relevant research to decisive and timely action in the field.

The design and development of a plastic optical fiber (POF) macrobend temperature sensor is presented. The sensor has a linear response versus temperature at a fixed bend radius, with a sensitivity of 1.92·10−3 (°C)−1. The sensor system used a dummy fiber-optic sensor for reference purposes having a resolution below 0.3 °C. A comprehensive experimental analysis was carried out to provide insight into the effect of different surrounding media on practical macro-bend POF sensor implementation. Experimental results are successfully compared with bend loss calculations. PMID:24077323

Strategy for an Extensible Microcomputer-Based Mumps System for Private Practice

A macro expander technique has been adopted to generate a machine independent single user version of ANSI Standard MUMPS running on an 8080 Microcomputer. This approach makes it possible to have the medically oriented MUMPS language available on inexpensive systems suitable for small group practice settings. Substitution of another macro expansion set allows the same interpreter to be implemented on another computer, thereby providing compatibility with comparable or larger scale systems. Furthermore, since the global file handler can be separated from the interpreter, this approach permits development of a distributed MUMPS system with no change in applications software.

Macroprolactin, big-prolactin and potential effects on the misdiagnosis of hyperprolactinemia using the Beckman Coulter Access Prolactin assay.

Ellis, M Jane; Livesey, John H; Soule, Steven G

2006-10-01

To examine whether use of the Beckman Coulter Access Prolactin (PRL) assay, which has low reactivity with macro-PRL, obviates the need for screening hyperprolactinemic samples. Samples from 1020 hyperprolactinemic individuals and 401 healthy volunteers were treated with polyethylene glycol (PEG). Macro-PRL was assessed from (1) percent PRL recovery, using cut-off values derived by gel filtration chromatography (GFC) and (2) significant (p<0.05) normalisation of PRL following PEG. PRL recovery was similar in volunteer and hyperprolactinemic samples (mean+/-SD 101+/-13% and 101+/-19%, respectively). In hyperprolactinemic samples, macro-PRL was identified from PRL recovery in 9.7%, although levels were moderate to high in only 3.9%. The total PRL normalised following PEG in 7.4%. Correlations of PRL recovery with the proportions of macro-, big- and monomeric PRL following GFC (n=30 samples, range of PRL and macro-PRL levels) were -0.89, -0.20 and 0.92, respectively. The big-PRL content was 0-28%. Regression analysis suggested that PEG precipitated both macro-PRL and big-PRL. Using the Access assay, macro-PRL can cause apparent hyperprolactinemia and big-PRL may cause misclassification of individuals. Screening using PEG is applicable to assays with low macro-PRL reactivity provided specific reference values are derived.

Laboratory measurements of electrical resistivity versus water content on small soil cores

The assessment of soil water content variations more and more leans on geophysical methods that are non invasive and that allow a high spatial sampling. Among the different methods, DC electrical imaging is moving forward. DC Electrical resistivity shows indeed strong seasonal variations that principally depend on soil water content variations. Nevertheless, the widely used Archie's empirical law [1], that links resistivity with voids saturation and water conductivity is not well suited to soil materials with high clay content. Furthermore, the shrinking and swelling properties of soil materials have to be considered. Hence, it is relevant to develop new laboratory experiments in order to establish a relation between electrical resistivity and water content taking into account the rheological and granulometrical specificities of soil materials. The experimental device developed in IRD laboratory allows to monitor simultaneously (i) the water content, (ii) the electrical resistivity and (iii) the volume of a small cylindrical soil core (100cm3) put in a temperature controlled incubator (30°C). It provides both the shrinkage curve of the soil core (voids volume versus water content) and the electrical resistivity versus water content curve The modelisation of the shrinkage curve gives for each moisture state the water respectively contained in macro and micro voids [2], and then allows to propose a generalized Archie's like law as following : 1/Rs = 1/Fma.Rma + 1/Fmi.Rmi and Fi = Ai/(Vi^Mi.Si^Ni) with Rs : the soil resistivity. Fma and Fmi : the so called "formation factor" for macro and micro voids, respectively. Rma and Rmi : the resistivity of the water contained in macro and micro voids, respectively. Vi : the volume of macro and micro voids, respectively. Si : the saturation of macro and micro voids, respectively. Ai, Mi and Ni : adjustment coefficients. The variations of Rmi are calculated, assuming that Rma is a constant. Indeed, the rise of ionic concentration in water may be neglected during the sewage of macro voids as it corresponds to a small quantity of water for the studied samples. Soil solid components are generally electrical insulators, the conduction of electrical current only lies on two phenomenon occurring in water : (i) volume conduction controlled by the electrolyte concentration in water and the geometrical characteristics of macro voids network ; (ii) surface conduction controlled by the double diffuse layer that depends on the solid-liquid interactions, the specific surface of clay minerals and the geometry of particles contacts. For the water contained in macro voids the preeminent phenomenon seems to be volume conduction while for the water contained in micro voids, it seems to be surface conduction. This hypothesis satisfyingly explains the shape of the electrical resistivity versus water content curves obtained for three different oxisols with clayey, clayey-sandy and sandy-clayey texture.

This computer note describes a method for creating trilinear plots in Microsoft Excel. Macros have been created in MS Excel's internal language: Visual Basic for Applications (VBA). A simple form has been set up to allow the user to input data from an Excel worksheet. The VBA macro is used to convert the triangular data (which consist of three columns of percentage data) into X-Y data. The macro then generates the axes, labels, and grid for the trilinear plot. The X-Y data are plotted as scatter data in Excel. By providing this macro in Excel, users can create trilinear plots in a quick, inexpensive manner.

Access to Power: Governance and Development in the Pakistani Electrical Power Sector

NASA Astrophysics Data System (ADS)

Naqvi, Ijlal

This dissertation explores governance in Pakistan through a study of the state-run electrical power sector. At both the micro and macro level, the Pakistani power sector provides a lens into the heart of the Pakistani state and its governance institutions. This ethnographic and historical study offers an in-depth look at state operations in a developing country, situates the current Pakistani power crisis in a larger context of continuity through periods of dictatorship and democracy, and suggests how efforts to make state service delivery more responsive to citizens might be reconceived. A historical review of the Pakistani power sector establishes first and foremost that the current crisis is the product of longer-term processes for which the policy solutions currently being proposed (with the support of international donors and multilateral lenders) are inadequate. Depoliticized attempts at power sector reform have little to offer in light of the pervasively informal and negotiated nature of the fragmented Pakistani state. The institutions of power sector governance are mutually constituted by the formal rules and the informal---personal relationships, language, violence, money, and power. These rules of the game are as relevant to relations within and between public sector organizations as they are to the engagement of citizens with their state. The same rules apply at the margins of the state---informal squatter settlements---as at the core, though the resources brought to bear and the resultant outcomes are different. The internal incoherence of this state underscores the limitations of formal rules in determining outcomes, and the poor prospects for reform efforts that focus exclusively on the formal aspects of governance. To proactively engage with the question of political will leads away from top-down policy perspectives and counter to the depoliticizing tendencies that currently shape policy reforms. Instead, an energized and informed local participation can be a counterweight to the inertial tendencies of a Pakistani state whose reforms tend to be co-opted by existing power centers rather than result in changed outcomes.

Evaluating the impact of bike network indicators on cyclist safety using macro-level collision prediction models.

Osama, Ahmed; Sayed, Tarek

2016-12-01

Many cities worldwide are recognizing the important role that cycling plays in creating green and livable communities. However, vulnerable road users such as cyclists are usually subjected to an elevated level of injury risk which discourages many road users to cycle. This paper studies cyclist-vehicle collisions at 134 traffic analysis zones in the city of Vancouver to assess the impact of bike network structure on cyclist safety. Several network indicators were developed using Graph theory and their effect on cyclist safety was investigated. The indicators included measures of connectivity, directness, and topography of the bike network. The study developed several macro-level (zonal) collision prediction models that explicitly incorporated bike network indicators as explanatory variables. As well, the models incorporated the actual cyclist exposure (bike kilometers travelled) as opposed to relying on proxies such as population or bike network length. The macro-level collision prediction models were developed using generalized linear regression and full Bayesian techniques, with and without spatial effects. The models showed that cyclist collisions were positively associated with bike and vehicle exposure. The exponents of the exposure variables were less than one which supports the "safety in numbers" hypothesis. Moreover, the models showed positive associations between cyclist collisions and the bike network connectivity and linearity indicators. In contrast, negative associations were found between cyclist collisions and the bike network continuity and topography indicators. The spatial effects were statistically significant in all of the developed models. Copyright © 2016 Elsevier Ltd. All rights reserved.

Diet, in addition to tobacco, alcohol and physical exercise, is a major factor contributing to chronic diseases in Europe. There is a pressing need for multidisciplinary research to promote healthier food choices and better diets. Food and Health Research in Europe (FAHRE) is a collaborative project commissioned by the European Union. Among its tasks is the description of national research systems for food and health and, in work reported here, the identification of strengths and gaps in the European research base. A typology of nine research themes was developed, spanning food, society, health and research structures. Experts were selected through the FAHRE partners, with balance for individual characteristics, and reported using a standardised template. Countries usually commission research on food, and on health, separately: few countries have combined research strategies or programmes. Food and health are also strongly independent fields within the European Commission's research programmes. Research programmes have supported food and bio-technology, food safety, epidemiological research, and nutritional surveillance; but there has been less research into personal behaviour and very little on environmental influences on food choices - in the retail and marketing industries, policy, and regulation. The research is mainly sited within universities and research institutes: there is relatively little published research contribution from industry. National food policies, based on epidemiological evidence and endorsed by the World Health Organisation, recommend major changes in food intake to meet the challenge of chronic diseases. Biomedical and biotechnology research, in areas such as 'nutrio-genomics', 'individualised' diets, 'functional' foods and 'nutri-pharmaceuticals' appear likely to yield less health benefit, and less return on public investment, than research on population-level interventions to influence dietary patterns: for example policies to reduce population consumption of trans fats, saturated fats, salt and energy density. Research should now address how macro-diets, rather than micro-nutritional content, can be improved for beneficial impacts on health, and should evaluate the impact of market changes and policy interventions, including regulation, to improve public health. European and national research on food and health should have social as well as commercial benefits. Strategies and policies should be developed between ministries of health and national research funding agencies. Collaboration between member states in the European Union can yield better innovation and greater competitive advantage.

(i) To explore dental, school and family perspectives of an oral health promotion (OHP) initiative to improve access for pre-school children in deprived communities; (ii) to develop a model of roles and responsibilities for OHP in community settings. Semi-structured focus groups (n = 6) with dental practice staff (n = 24), and semi-structured interviews with school staff (n = 9) and parents and children (n = 4) who were involved in an OHP initiative for pre-school children. Framework analysis was applied to identify themes. Themes were used to develop a model of roles and responsibilities for OHP, based on the WHO Planning and evaluating health promotion model. Respondents subscribed to a community-based approach to improving access to dental services for pre-school children in deprived areas, with an emphasis on shared responsibility and communication. In addition to macro-level actions in directing health policy and services, commissioners were held responsible for investing in micro-level actions, such as funding OHP training and involving parents, and meso-level actions such as reducing barriers to access. The model we have developed builds on WHO recommendations on health promotion to identify the key roles and responsibilities that should be incorporated into further initiatives in OHP.

2007-01-01

The HIV/AIDS epidemic has impacted all levels of society from the individual to the macro-economic. The continuing spread of infection around the world means that traditional methods of care and support are put under extreme pressure and many families lose their capacity to cope. Social workers are involved in providing care, counseling and support to those affected, and in developing programmes and other interventions to prevent the spread of the disease. Prevention and behaviour change are vital, but access to treatment is an ethical imperative, particularly in developing countries where the epidemic is most prevalent. Social work is a profession uniquely situated to demonstrate leadership in multi-sectoral collaboration in responding to this pandemic. Consequently this paper briefly reviews the scale and current nature of the epidemic and then considers how social workers can help build more compassionate policies at an international level. Social workers can help to create awareness of the negative effects of poverty, tackle gender inequity, help build more effective coalitions and partnerships, and work with other concerned groups and organisations to end stigma and discrimination. Using case examples the paper considers how social workers can help develop caring strategies that improve the lives of those living with HIV and AIDS.

This study examines the multi-level functionalities of social media in the aftermath of the Great East Japan Earthquake of 11 March 2011. Based on a conceptual model of multi-level story flows of social media (Jung and Moro, 2012), the study analyses the multiple functionalities that were ascribed to social media by individuals, organisations, and macro-level social systems (government and the mass media) after the earthquake. Based on survey data, a review of Twitter timelines and secondary sources, the authors derive five functionalities of social media: interpersonal communications with others (micro level); channels for local governments; organisations and local media (meso level); channels for mass media (macro level); information sharing and gathering (cross level); and direct channels between micro-/meso- and macro-level agents. The study sheds light on the future potential of social media in disaster situations and suggests how to design an effective communication network to prepare for emergency situations. © 2014 The Author(s).

The current trend of bio-electrochemical systems is to improve strategies related to their applicability and potential for scaling-up. To date, literature has suggested strategies, but the proposal of correlations between each research field remains insufficient. This review paper provides a correlation based on platform techniques, referred to as bio-electronics platforms (BEPs). These BEPs consist of three platforms divided by scope scale: nano-, micro-, and macro-BEPs. In the nano-BEP, several types of electron transfer mechanisms used by electrochemically active bacteria are discussed. In the micro-BEP, factors affecting the formation of conductive biofilms and transport of electrons in the conductive biofilm are investigated. In the macro-BEP, electrodes and separators in bio-anode are debated in terms of real applications, and a scale-up strategy is discussed. Overall, the challenges of each BEP are highlighted, and potential solutions are suggested. In addition, future research directions are provided and research ideas proposed to develop research interest. Copyright © 2015 Elsevier Ltd. All rights reserved.

A macro-/mesoporous Co-N-C-decorated separator is proposed to confine and reutilize migrating polysulfides. Endowed with a desirable structure and synchronous lithio- and sulfiphilic chemistry, the macro-/mesoporous Co-N-C interface manipulates large polysulfide adsorption uptake, enabling good polysulfide adsorption kinetics, reversible electrocatalysis toward redox of anchored polysulfides, and facile charge transport. It significantly boosts the performance of a simple 70 wt % S/MWCNTs (MWCNTs=multi-walled carbon nanotubes) cathode, achieving high initial capacities (e.g., 1406 mAh g -1 at 0.2C, 1203 mAh g -1 at 1C), nearly 100 % Coulombic efficiencies, and high reversible capacities after cycle tests (e.g., 828.4 mAh g -1 at 1C after 100 cycles) at both low and high current rates. These results demonstrate that decorating separator with macro-/mesoporous Co-N-C paves a feasible way for developing advanced Li-S batteries. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

The current challenge in sustainable agriculture is to introduce new cropping systems to reduce pesticides use in order to reduce ground and surface water contamination. However, it is difficult to carry out in situ experiments to assess the environmental impacts of pesticide use for all possible combinations of climate, crop, and soils; therefore, in silico tools are necessary. The objective of this work was to assess pesticides leaching in cropping systems coupling the performances of a crop model (STICS) and of a pesticide fate model (MACRO). STICS-MACRO has the advantage of being able to simulate pesticides fate in complex cropping systems and to consider some agricultural practices such as fertilization, mulch, or crop residues management, which cannot be accounted for with MACRO. The performance of STICS-MACRO was tested, without calibration, from measurements done in two French experimental sites with contrasted soil and climate properties. The prediction of water percolation and pesticides concentrations with STICS-MACRO was satisfactory, but it varied with the pedoclimatic context. The performance of STICS-MACRO was shown to be similar or better than that of MACRO. The improvement of the simulation of crop growth allowed better estimate of crop transpiration therefore of water balance. It also allowed better estimate of pesticide interception by the crop which was found to be crucial for the prediction of pesticides concentrations in water. STICS-MACRO is a new promising tool to improve the assessment of the environmental risks of pesticides used in cropping systems.

An optical analysis is developed to separate forward light scatter of the human eye from the conventional wavefront aberrations in a double pass optical system. To quantify the separate contributions made by these micro- and macro-aberrations, respectively, to the spot image blur in the Shark-Hartmann aberrometer, we develop a metric called radial variance for spot blur. We prove an additivity property for radial variance that allows us to distinguish between spot blurs from macro-aberrations and micro-aberrations. When the method is applied to tear break-up in the human eye, we find that micro-aberrations in the second pass accounts for about 87% of the double pass image blur in the Shack-Hartmann wavefront aberrometer under our experimental conditions. © 2011 Optical Society of America

The influence of the macro-environment on physical activity: a multilevel analysis of 38 countries worldwide

PubMed Central

2012-01-01

Background As indicated by the ANGELO framework and similar models, various environmental factors influence population levels of physical activity (PA). To date attention has focused on the micro-level environment, while evidence on the macro-level environment remains scarce and mostly limited to high-income countries. This study aims to investigate whether environmental factors at macro-level are associated with PA among a broader range of countries. Methods Data from the World Health Survey (WHS) was used to analyze 177,035 adults from 38 (mostly low and middle income) countries. The International Physical Activity Questionnaire-Short Form (IPAQ-S) was used to measure PA. Respondents were classified as active or inactive for vigorous PA, moderate PA and walking. Multilevel logistic regression was performed to assess associations between macro-level environmental factors and the prevalence of PA, with control for individual-level socioeconomic factors. Results The prevalence of PA varied widely between countries and types of PA (5.0%-93.8%). A negative association was found between gross domestic product and PA, odds ratios for men were 0.76 (95% CI: 0.65-0.89) for moderate PA and 0.79 (95% CI: 0.63-0.98) for walking. A higher temperature was associated with less PA (all types) and higher urbanization was associated with less vigorous and moderate PA. More gender equality was also associated with more walking for women. Governmental functioning and literacy rate were not found to be associated with any type of PA. Conclusions This exploratory study indicates that factors such as climate, economic development and cultural factors are determinants of the level of overall PA at national levels. This underlines the suggestion that the macro-environment should be regarded as an important influence on PA. PMID:22967164

This underlines the suggestion that the macro-environment should be regarded as an important influence on PA.

The exact etiology and pathogenesis of eczema are not yet fully understood, although different factors are considered as pathogenic mechanisms in the development of eczema. Our study was designed to determine extent of serum lipid peroxidation, antioxidants, macro minerals and trace elements in patients with eczema, and thereby, find any pathophysiological correlation. The study was conducted as a case-control study with 65 eczema patients as cases and 65 normal healthy individuals as controls. Lipid peroxidation was assessed by measuring the serum level of malondialdehyde (MDA). Antioxidants- vitamin A and E concentration was determined by RP-HPLC method whereas vitamin C was evaluated for serum ascorbic acid by UV spectrophotometric method. Serum macro minerals (Na, K, Ca) and trace elements (Zn, Fe) were determined by Atomic Absorption Spectroscopy (AAS). This study found significantly higher level of MDA (p < 0.001) and lower level of antioxidants (p < 0.05) in patients in comparison to the control subjects. Analysis of serum macro minerals (Na, K and Ca) and trace elements (Zn, Fe) found that the mean values of Na, K, Ca, Zn and Fe were 2771.60 ± 75.64, 66.33 ± 3.03, 48.41 ± 2.50, 0.30 ± 0.02 and 0.29 ± 0.009 mg/L for the patient group and 3284.81 ± 34.51, 162.18 ± 3.72, 87.66 ± 2.10, 0.75 ± 0.06 and 0.87 ± 0.06 mg/L for the control group, accordingly. There was a significant difference for all the minerals between the patients and controls (p < 0.001). This study suggests a strong association between the pathogenesis of eczema with the elevated level of MDA and depleted level of antioxidants, macro minerals, and trace elements.

Background: Priority setting in healthcare is a key determinant of health system performance. However, there is no widely accepted priority setting evaluation framework. We reviewed literature with the aim of developing and proposing a framework for the evaluation of macro and meso level healthcare priority setting practices. Methods: We systematically searched Econlit, PubMed, CINAHL, and EBSCOhost databases and supplemented this with searches in Google Scholar, relevant websites and reference lists of relevant papers. A total of 31 papers on evaluation of priority setting were identified. These were supplemented by broader theoretical literature related to evaluation of priority setting. A conceptual review of selected papers was undertaken. Results: Based on a synthesis of the selected literature, we propose an evaluative framework that requires that priority setting practices at the macro and meso levels of the health system meet the following conditions: (1) Priority setting decisions should incorporate both efficiency and equity considerations as well as the following outcomes; (a) Stakeholder satisfaction, (b) Stakeholder understanding, (c) Shifted priorities (reallocation of resources), and (d) Implementation of decisions. (2) Priority setting processes should also meet the procedural conditions of (a) Stakeholder engagement, (b) Stakeholder empowerment, (c) Transparency, (d) Use of evidence, (e) Revisions, (f) Enforcement, and (g) Being grounded on community values. Conclusion: Available frameworks for the evaluation of priority setting are mostly grounded on procedural requirements, while few have included outcome requirements. There is, however, increasing recognition of the need to incorporate both consequential and procedural considerations in priority setting practices. In this review, we adapt an integrative approach to develop and propose a framework for the evaluation of priority setting practices at the macro and meso levels that draws from these complementary schools of thought.

Lee, Young Han; Park, Eun Hae; Suh, Jin-Suck

2015-01-01

The objectives are: 1) to introduce a simple and efficient method for extracting region of interest (ROI) values from a Picture Archiving and Communication System (PACS) viewer using optical character recognition (OCR) software and a macro program, and 2) to evaluate the accuracy of this method with a PACS workstation. This module was designed to extract the ROI values on the images of the PACS, and created as a development tool by using open-source OCR software and an open-source macro program. The principal processes are as follows: (1) capture a region of the ROI values as a graphic file for OCR, (2) recognize the text from the captured image by OCR software, (3) perform error-correction, (4) extract the values including area, average, standard deviation, max, and min values from the text, (5) reformat the values into temporary strings with tabs, and (6) paste the temporary strings into the spreadsheet. This principal process was repeated for the number of ROIs. The accuracy of this module was evaluated on 1040 recognitions from 280 randomly selected ROIs of the magnetic resonance images. The input times of ROIs were compared between conventional manual method and this extraction module-assisted input method. The module for extracting ROI values operated successfully using the OCR and macro programs. The values of the area, average, standard deviation, maximum, and minimum could be recognized and error-corrected with AutoHotkey-coded module. The average input times using the conventional method and the proposed module-assisted method were 34.97 seconds and 7.87 seconds, respectively. A simple and efficient method for ROI value extraction was developed with open-source OCR and a macro program. Accurate inputs of various numbers from ROIs can be extracted with this module. The proposed module could be applied to the next generation of PACS or existing PACS that have not yet been upgraded. Copyright © 2015 AUR. Published by Elsevier Inc. All rights reserved.

An appraisal of policies and institutional frameworks impacting on smallholder agricultural water management in Zimbabwe

NASA Astrophysics Data System (ADS)

Nyagumbo, I.; Rurinda, J.

Policies and institutional frameworks associated with and / or impacting on agricultural water management (AWM) in smallholder farming systems in Zimbabwe were analyzed through literature reviews, feedback from stakeholder workshops, key informant interviews and evaluation of policy impacts on implemented case study projects/programmes. The study showed that Zimbabwe has gone a long way towards developing a water management policy addressing both equity and access, through the Water and ZINWA of 1998. However, lack of incentives for improving efficient management and utilization of water resources once water has reached the farm gate was apparent, apart from punitive economic instruments levied on usage of increased volumes of water. For example, the new water reforms of 1998 penalized water savers through loss of any unused water in their permits to other users. In addition, the ability of smallholder farmers to access water for irrigation or other purposes was influenced by macro and micro-economic policies such as Economic Structural and Adjustment Programme (ESAP), Zimbabwe Programme for Economic and Social Transformation (ZIMPREST), prevailing monetary and fiscal policies, as well as the Land and Agrarian Reform policies. For instance, the implementation of ESAP from 1991 to 95 resulted in a decline in government support to management of communal irrigation schemes, and as a result only gravity-fed schemes survived. Also AWM projects/programmes that were in progress were prematurely terminated. While considerable emphasis was placed on rehabilitation of irrigation infrastructure since the fast track land reform in 1998, the policies remained rather silent on strategies for water management in rainfed systems. The piecemeal nature and fragmentation of policies and institutional frameworks scattered across government ministries and sectors were complex and created difficulties for smallholder farmers to access water resources. Poor policy implementation strategies and lack of funding were some of the major weaknesses in Zimbabwe’s AWM policies. It was apparent that the prevailing institutional frameworks that underwent restructuring exercises since 2000, failed to effectively deliver services to smallholder farmers due to lack of human and financial capital. Nevertheless, the study showed that policies that can improve efficient utilization of agricultural water in rainfed systems need to target timely provision of the prime movers, i.e. credit, input markets and viable output markets, among other factors, so as to fully utilize good rainfall seasons. It was recommended that a forum led by ZINWA be set up to harmonize AWM issues across sectors and monitor their implementation. Such a forum would be mandated mainly to run periodic water management workshops in which relevant and interested stakeholders participate. ZINWA stands for Zimbabwe National Water Authority.

Primordial 4He constraints on inelastic macro dark matter revisited

NASA Astrophysics Data System (ADS)

Jacobs, David M.; Allwright, Gwyneth; Mafune, Mpho; Manikumar, Samyukta; Weltman, Amanda

2016-11-01

At present, the best model for the evolution of the cosmos requires that dark matter make up approximately 25% of the energy content of the Universe. Most approaches to explain the microscopic nature of dark matter, to date, have assumed its composition to be of intrinsically weakly interacting particles; however, this need not be the case to have consistency with all extant observations. Given decades of inconclusive evidence to support any dark matter candidate, there is strong motivation to consider alternatives to the standard particle scenario. One such example is macro dark matter, a class of candidates (macros) that could interact strongly with the particles of the Standard Model, have large masses and physical sizes, and yet behave as dark matter. Macros that scatter completely inelastically could have altered the primordial production of the elements, and macro charge-dependent constraints have been obtained previously. Here we reconsider the phenomenology of inelastically interacting macros on the abundance of primordially produced 4He and revise previous constraints by also taking into account improved measurements of the primordial 4He abundance. The constraints derived here are limited in applicability to only leptophobic macros that have a surface potential V (RX)≳0.5 MeV . However, an important conclusion from our analysis is that even neutral macros would likely affect the abundance of the light elements. Therefore, constraints on that scenario are possible and are currently an open question.

Should structural interventions be evaluated using RCTs? The case of HIV prevention.

PubMed

Bonell, Christopher; Hargreaves, James; Strange, Vicki; Pronyk, Paul; Porter, John

2006-09-01

Structural interventions addressing macro-social determinants of risk have been suggested as potentially important adjuncts to biomedical and behavioural interventions for the prevention of HIV and other diseases. A few interventions of this type have been evaluated using randomised controlled trials (RCTs), the most rigorous design to evaluate the effects of biomedical and behavioural interventions. The appropriateness of applying RCTs to structural interventions is however debated. This paper considers whether issues of ethics, feasibility and utility preclude the use of RCTs in evaluations of structural interventions for HIV prevention. We conclude there is nothing particular to this category of interventions prohibiting use of RCTs. However, we suggest that RCTs may prove unacceptable, unfeasible or not useful in certain circumstances, such as where an intervention brings important benefits other than HIV prevention (such as increased income); where leaders of clusters do not allow decisions about macro-social policies to be determined randomly; where the unit of social organization addressed by an intervention is so large that recruitment of adequate numbers of clusters is impossible; and where the period required to trial interventions extends beyond practical decision-making time-scales. In such cases, alternative evaluative designs must be assessed for their ability to provide evidence of intervention effectiveness.

Evaluating Water Demand Using Agent-Based Modeling

NASA Astrophysics Data System (ADS)

Lowry, T. S.

2004-12-01

The supply and demand of water resources are functions of complex, inter-related systems including hydrology, climate, demographics, economics, and policy. To assess the safety and sustainability of water resources, planners often rely on complex numerical models that relate some or all of these systems using mathematical abstractions. The accuracy of these models relies on how well the abstractions capture the true nature of the systems interactions. Typically, these abstractions are based on analyses of observations and/or experiments that account only for the statistical mean behavior of each system. This limits the approach in two important ways: 1) It cannot capture cross-system disruptive events, such as major drought, significant policy change, or terrorist attack, and 2) it cannot resolve sub-system level responses. To overcome these limitations, we are developing an agent-based water resources model that includes the systems of hydrology, climate, demographics, economics, and policy, to examine water demand during normal and extraordinary conditions. Agent-based modeling (ABM) develops functional relationships between systems by modeling the interaction between individuals (agents), who behave according to a probabilistic set of rules. ABM is a "bottom-up" modeling approach in that it defines macro-system behavior by modeling the micro-behavior of individual agents. While each agent's behavior is often simple and predictable, the aggregate behavior of all agents in each system can be complex, unpredictable, and different than behaviors observed in mean-behavior models. Furthermore, the ABM approach creates a virtual laboratory where the effects of policy changes and/or extraordinary events can be simulated. Our model, which is based on the demographics and hydrology of the Middle Rio Grande Basin in the state of New Mexico, includes agent groups of residential, agricultural, and industrial users. Each agent within each group determines its water usage based on its own condition and the condition of the world around it. For example, residential agents can make decisions to convert to or from xeriscaping and/or low-flow appliances based on policy implementation, economic status, weather, and climatic conditions. Agricultural agents may vary their usage by making decisions on crop distribution and irrigation design. Preliminary results show that water usage can be highly irrational under certain conditions. Results also identify sub-sectors within each group that have the highest influence on ensemble group behavior, providing a means for policy makers to target their efforts. Finally, the model is able to predict the impact of low-probability, high-impact events such as catastrophic denial of service due to natural and/or man-made events.

Understanding competition between healthcare providers: Introducing an intermediary inter-organizational perspective.

2017-02-01

Pro-competitive policy reforms have been introduced in several countries, attempting to contain increasing healthcare costs. Yet, research proves ambiguous when it comes to the effect of competition in healthcare, with a number of studies highlighting unintended and unwanted effects. We argue that current empirical work overlooks the role of inter-organizational relations as well as the interplay between policy at macro level, inter-organizational networks at meso level, and outcomes at micro level. To bridge this gap and stimulate a more detailed understanding of the effect of competition in health care, this article introduces a cross-level conceptual framework which emphasizes the intermediary role of cooperative inter-organizational relations at meso level. We discuss how patient transfers, specialist affiliations, and interlocking directorates constitute three forms of inter-organizational relations in health care which can be used within this framework. The paper concludes by deriving several propositions from the framework which can guide future research. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

[Effects of macro-jellyfish abundance dynamics on fishery resource structure in the Yangtze River estuary and its adjacent waters].

Based on the bottom trawl survey data in May 2007 and May and June 2008, this paper analyzed the effects of the abundance dynamics of macro-jellyfish on the species composition, distribution, and abundance of fishery resource in the Yangtze River estuary and its adjacent waters. From May 2007 to June 2008, the average catch per haul and the top catch per haul of macro-jellyfish increased, up to 222.2 kg x h(-1) and 1800 kg x h(-1) in June 2008, respectively. The macro-jellyfish were mainly distributed in the areas around 50 m isobath, and not beyond 100 m isobath where was the joint front of the coastal waters of East China Sea, Yangtze River runoff, and Taiwan Warm Current. The main distribution area of macro-jellyfish in June migrated northward, as compared with that in May, and the highest catches of macro-jellyfish in May 2007 and May 2008 were found in the same sampling station (122.5 degrees E, 28.5 degrees N). In the sampling stations with higher abundance of macro-jellyfish, the fishery abundance was low, and the fishery species also changed greatly, mainly composed by small-sized species (Trachurus japonicus, Harpadon nehereus, and Acropoma japonicum) and pelagic species (Psenopsis anomala, Octopus variabilis) and Trichiurus japonicus, and P. anomala accounted for 23.7% of the total catch in June 2008. Larimichthys polyactis also occupied higher proportion of the total catch in sampling stations with higher macro-jellyfish abundance, but the demersal species Lophius litulon was not found, and a few crustaceans were collected. This study showed that macro-jellyfish had definite negative effects on the fishery community structure and abundance in the Yangtze River estuary fishery ecosystem, and further, changed the energy flow patterns of the ecosystem through cascading trophic interactions. Therefore, macro-jellyfish was strongly suggested to be an independent ecological group when the corresponding fishery management measures were considered.

Food security in an era of economic volatility.

PubMed

Naylor, Rosamond L; Falcon, Walter P

2010-01-01

This article analyzes international commodity price movements, assesses food policies in response to price fluctuations, and explores the food security implications of price volatility on low-income groups. It focuses specifically on measurements, causes, and consequences of recent food price trends, variability around those trends, and price spikes. Combining these three components of price dynamics shows that the variation in real prices post-2000 was substantially greater than that in the 1980s and 1990s, and was approximately equal to the extreme volatility in commodity prices that was experienced in the 1970s. Macro policy, exchange rates, and petroleum prices were important determinants of price variability over 2005–2010, highlighting the new linkages between the agriculture-energy and agriculture-finance markets that affect the world food economy today. These linkages contributed in large part to misguided expectations and uncertainty that drove prices to their peak in 2008. The article also argues that there is a long-lasting effect of price spikes on food policy around the world, often resulting in self-sufficiency policies that create even more volatility in international markets. The efforts by governments to stabilize prices frequently contribute to even greater food insecurity among poor households, most of which are in rural areas and survive on the margin of net consumption and net production. Events of 2008—and more recently in 2010—underscore the impact of price variability for food security and the need for refocused policy approaches to prevent and mitigate price spikes.

Crowd macro state detection using entropy model

2015-08-01

In the crowd security research area a primary concern is to identify the macro state of crowd behaviors to prevent disasters and to supervise the crowd behaviors. The entropy is used to describe the macro state of a self-organization system in physics. The entropy change indicates the system macro state change. This paper provides a method to construct crowd behavior microstates and the corresponded probability distribution using the individuals' velocity information (magnitude and direction). Then an entropy model was built up to describe the crowd behavior macro state. Simulation experiments and video detection experiments were conducted. It was verified that in the disordered state, the crowd behavior entropy is close to the theoretical maximum entropy; while in ordered state, the entropy is much lower than half of the theoretical maximum entropy. The crowd behavior macro state sudden change leads to the entropy change. The proposed entropy model is more applicable than the order parameter model in crowd behavior detection. By recognizing the entropy mutation, it is possible to detect the crowd behavior macro state automatically by utilizing cameras. Results will provide data support on crowd emergency prevention and on emergency manual intervention.

Challenges in getting workforce research in nursing used for decision-making in policy and practice: a Canadian perspective.

2008-12-01

This paper draws upon empirical research and other published sources to discuss nursing workforce issues, the challenges of using health human resource research in policy decisions and the importance of evidence-based policies and practices for nursing care and outcomes. Increasing evidence points to the critical relationship between registered nurse care and improved patient outcomes. The negative impact that insufficient nurse staffing has on patient, nursing and system outcomes has influenced health human resource researchers to further examine nurses' work environments to determine factors that are amenable to policy change. Survey of literature was conducted. Electronic databases were searched using keywords. Sustained health human resource planning efforts by policy makers are difficult given changing governments and political agendas. The health human resource conceptual framework provides researchers and planners with a guide to decision-making that considers current circumstances as well as those factors that need to be accounted for in predicting future requirements. However, effective use of research depends on communication of findings between researchers and policymakers. Health care managers and other decision-makers in health care organisations often lack an understanding of the research process and do not always have easy access to current evidence. Also, managerial decisions are often constrained by organisational requirements such as resource availability and policies and procedures. Unless nursing workplace issues are addressed, the physiological and psychological stress in the work environments of nurses will continue. Effective health human resource policy and planning (at the macro level) and management strategies (at the micro level) would stabilise the nursing workforce and reduce job stress. Furthermore, the efficiency and cost-effectiveness of the health system could be enhanced through improved health outcomes of care providers and health care clients.

The goal of this report is to inform investors about the potential of solar minigrid technologies to serve India's rural market. Under the US-India Energy Dialogue, the US Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) is supporting the Indian Ministry of New and Renewable Energy (MNRE)'s Jawaharlal Nehru National Solar Mission (JNNSM) in performing a business-case and policy-oriented analysis on the deployment of solar minigrids in India. The JNNSM scheme targets the development of 2GW of off-grid solar power by 2022 and provides large subsidies to meet this target. NREL worked with electricity capacity and demand data suppliedmore » by the Ladakh Renewable Energy Development Agency (LREDA) from Leh District, to develop a technical approach for solar minigrid development. Based on the NREL-developed, simulated solar insolation data for the city of Leh, a 250-kW solar photovoltaic (PV) system can produce 427,737 kWh over a 12-month period. The business case analysis, based on several different scenarios and JNNSM incentives shows the cost of power ranges from Rs. 6.3/kWh (US$0.126) to Rs. 9/kWh (US$0.18). At these rates, solar power is a cheaper alternative to diesel. An assessment of the macro-environment elements--including political, economic, environmental, social, and technological--was also performed to identify factors that may impact India?s energy development initiatives.« less

A cross-comparison of different techniques for modeling macro-level cyclist crashes.

2018-04-01

Despite the recognized benefits of cycling as a sustainable mode of transportation, cyclists are considered vulnerable road users and there are concerns about their safety. Therefore, it is essential to investigate the factors affecting cyclist safety. The goal of this study is to evaluate and compare different approaches of modeling macro-level cyclist safety as well as investigating factors that contribute to cyclist crashes using a comprehensive list of covariates. Data from 134 traffic analysis zones (TAZs) in the City of Vancouver were used to develop macro-level crash models (CM) incorporating variables related to actual traffic exposure, socio-economics, land use, built environment, and bike network. Four types of CMs were developed under a full Bayesian framework: Poisson lognormal model (PLN), random intercepts PLN model (RIPLN), random parameters PLN model (RPPLN), and spatial PLN model (SPLN). The SPLN model had the best goodness of fit, and the results highlighted the significant effects of spatial correlation. The models showed that the cyclist crashes were positively associated with bike and vehicle exposure measures, households, commercial area density, and signal density. On the other hand, negative associations were found between cyclist crashes and some bike network indicators such as average edge length, average zonal slope, and off-street bike links.

Jan, Kulsum; Riar, C S; Saxena, D C

2015-12-01

Different agro-industrial wastes were mixed with different plasticizers and extruded to form the pellets to be used further for development of biodegradable molded pots. Bulk density and macro-porosity are the important engineering properties used to determine the functional characteristics of the biodegradable pellets viz., expansion volume, water solubility, product colour, flowability and compactness. Significant differences in the functional properties of pellets with varying bulk densities (loose and tapped) and macro-porosities (loose, tapped) were observed. The observed mean bulk density of biodegradable pellets made from different formulations ranged between 0.213 and 0.560 g/ml for loose fill conditions and 0.248 to 0.604 g/ml for tapped fill conditions. Biodegradable pellets bear a good compaction for both loose and tapped fill methods. The mean macro-porosity of biodegradable pellets ranged between 1.19 and 54.48 % for loose fill condition and 0.29 to 53.35 % for tapped fill condition. Hausner ratio (HR) for biodegradable pellets varied from 1.026 to 1.328, indicating a good flowability of biodegradable pellets. Pearson's correlation between engineering properties and functional properties of biodegradable pellets revealed that from engineering properties functional properties can be predicted.

Priority setting in health care: on the relation between reasonable choices on the micro-level and the macro-level.

PubMed

Baerøe, Kristine

2008-01-01

There has been much discussion about how to obtain legitimacy at macro-level priority setting in health care by use of fair procedures, but how should we consider priority setting by individual clinicians or health workers at the micro-level? Despite the fact that just health care totally hinges upon their decisions, surprisingly little attention seems being paid to the legitimacy of these decisions. This paper addresses the following question: what are the conditions that have to be met in order to ensure that individual claims on health care are well aligned with an overall concept of just health care? Drawing upon a distinction between individual and aggregated needs, I argue that even though we assume the legitimacy of macro-level guidelines, this legitimacy is not directly transferable to decisions at micro-level simply by adherence to the guidelines' recommendation. Further, I argue that individual claims are subject to the formal principle of equality and the demands of vertical and horizontal equity in a way that gives context- and patient-related equity concerns precedence over equity concerns captured at the macro-level. I conclude that if we aim to achieve just health care, we need to develop a complementary framework for legitimising individual judgment of patients' claims on health care resources. Moreover, I suggest the basic structure of such a framework.

Cross-national and multilevel correlates of partner violence: an analysis of data from population-based surveys.

PubMed

Heise, Lori L; Kotsadam, Andreas

2015-06-01

On average, intimate partner violence affects nearly one in three women worldwide within their lifetime. But the distribution of partner violence is highly uneven, with a prevalence of less than 4% in the past 12 months in many high-income countries compared with at least 40% in some low-income settings. Little is known about the factors that drive the geographical distribution of partner violence or how macro-level factors might combine with individual-level factors to affect individual women's risk of intimate partner violence. We aimed to assess the role that women's status and other gender-related factors might have in defining levels of partner violence among settings. We compiled data for the 12 month prevalence of partner violence from 66 surveys (88 survey years) from 44 countries, representing 481 205 women between Jan 1, 2000, and Apr 17, 2013. Only surveys with comparable questions and state-of-the-art methods to ensure safety and encourage violence disclosure were used. With linear and quantile regression, we examined associations between macro-level measures of socioeconomic development, women's status, gender inequality, and gender-related norms and the prevalence of current partner violence at a population level. Multilevel modelling and tests for interaction were used to explore whether and how macro-level factors affect individual-level risk. The outcome for this analysis was the population prevalence of current partner violence, defined as the percentage of ever-partnered women (excluding widows without a current partner), aged from 15 years to 49 years who were victims of at least one act of physical or sexual violence within the past 12 months. Gender-related factors at the national and subnational level help to predict the population prevalence of physical and sexual partner violence within the past 12 months. Especially predictive of the geographical distribution of partner violence are norms related to male authority over female behaviour (0·102, p<0·0001), norms justifying wife beating (0·263, p<0·0001), and the extent to which law and practice disadvantage women compared with men in access to land, property, and other productive resources (0·271, p<0·0001). The strong negative association between current partner violence and gross domestic product (GDP) per person (-0·055, p=0·0009) becomes non-significant in the presence of norm-related measures (-0·015, p=0·472), suggesting that GDP per person is a marker for social transformations that accompany economic growth and is unlikely to be causally related to levels of partner violence. We document several cross-level effects, including that a girl's education is more strongly associated with reduced risk of partner violence in countries where wife abuse is normative than where it is not. Likewise, partner violence is less prevalent in countries with a high proportion of women in the formal work force, but working for cash increases a woman's risk in countries where few women work. Our findings suggest that policy makers could reduce violence by eliminating gender bias in ownership rights and addressing norms that justify wife beating and male control of female behaviour. Prevention planners should place greater emphasis on policy reforms at the macro-level and take cross-level effects into account when designing interventions.

We generalize the concept of charge regulation of ionic solutions, and apply it to complex fluids with mobile macro-ions having internal non-electrostatic degrees of freedom. The suggested framework provides a convenient tool for investigating systems where mobile macro-ions can self-regulate their charge (e.g., proteins). We show that even within a simplified charge-regulation model, the charge dissociation equilibrium results in different and notable properties. Consequences of the charge regulation include a positional dependence of the effective charge of the macro-ions, a non-monotonic dependence of the effective Debye screening length on the concentration of the monovalent salt, a modification of the electric double-layer structure, and buffering by the macro-ions of the background electrolyte.

The objective of this paper is to survey and determine the macroeconomic factors affecting the level of venture capital (VC) investments in a country. The literary depends on venture capitalists' quality and countries' venture capital investments. The aim of this paper is to give relationship between venture capital investment and macro economic variables via statistical computation method. We investigate the countries and macro economic variables. By using statistical computation method, we derive correlation between venture capital investments and macro economic variables. According to method of logistic regression model (logit regression or logit model), macro economic variables are correlated with each other in three group. Venture capitalists regard correlations as a indicator. Finally, we give correlation matrix of our results.

1974-01-01

Two techniques are discussed that have been most often referred to as structured programming. One is that of programming with high level control structures (such as the if and while) replacing the branch instruction (goto-less programming); the other is the process of developing a program by progressively refining descriptions of components in terms of more primitive components (called stepwise refinement or top-down programming). In addition to discussing what these techniques are, it is shown why their use is advised and how both can be implemented in OS assembly language by the use of a special macro instruction package.

The output power fluctuations caused by weights of macro particles used in particle-in-cell (PIC) simulations of a backward wave oscillator and a travelling wave tube are statistically analyzed. It is found that the velocities of electrons passed a specific slow-wave structure form a specific electron velocity distribution. The electron velocity distribution obtained in PIC simulation with a relative small weight of macro particles is considered as an initial distribution. By analyzing this initial distribution with a statistical method, the estimations of the output power fluctuations caused by different weights of macro particles are obtained. The statistical method is verified bymore » comparing the estimations with the simulation results. The fluctuations become stronger with increasing weight of macro particles, which can also be determined reversely from estimations of the output power fluctuations. With the weights of macro particles optimized by the statistical method, the output power fluctuations in PIC simulations are relatively small and acceptable.« less

A finite model updating method that combines dynamic-static long-gauge strain responses is proposed for highway bridge static loading tests. For this method, the objective function consisting of static long-gauge stains and the first order modal macro-strain parameter (frequency) is established, wherein the local bending stiffness, density and boundary conditions of the structures are selected as the design variables. The relationship between the macro-strain and local element stiffness was studied first. It is revealed that the macro-strain is inversely proportional to the local stiffness covered by the long-gauge strain sensor. This corresponding relation is important for the modification of the local stiffness based on the macro-strain. The local and global parameters can be simultaneously updated. Then, a series of numerical simulation and experiments were conducted to verify the effectiveness of the proposed method. The results show that the static deformation, macro-strain and macro-strain modal can be predicted well by using the proposed updating model. PMID:28753912

Histone variants are structural components of eukaryotic chromatin that can replace replication-coupled histones in the nucleosome. The histone variant macroH2A1.1 contains a macrodomain capable of binding NAD + -derived metabolites. Here we report that macroH2A1.1 is rapidly induced during myogenic differentiation through a switch in alternative splicing, and that myotubes that lack macroH2A1.1 have a defect in mitochondrial respiratory capacity. We found that the metabolite-binding macrodomain was essential for sustained optimal mitochondrial function but dispensable for gene regulation. Through direct binding, macroH2A1.1 inhibits basal poly-ADP ribose polymerase 1 (PARP-1) activity and thus reduces nuclear NAD + consumption. The resultant accumulation of the NAD + precursor NMN allows for maintenance of mitochondrial NAD + pools that are critical for respiration. Our data indicate that macroH2A1.1-containing chromatin regulates mitochondrial respiration by limiting nuclear NAD + consumption and establishing a buffer of NAD + precursors in differentiated cells.

The application of system dynamics modelling to environmental health decision-making and policy - a scoping review.

Currie, Danielle J; Smith, Carl; Jagals, Paul

2018-03-27

Policy and decision-making processes are routinely challenged by the complex and dynamic nature of environmental health problems. System dynamics modelling has demonstrated considerable value across a number of different fields to help decision-makers understand and predict the dynamic behaviour of complex systems in support the development of effective policy actions. In this scoping review we investigate if, and in what contexts, system dynamics modelling is being used to inform policy or decision-making processes related to environmental health. Four electronic databases and the grey literature were systematically searched to identify studies that intersect the areas environmental health, system dynamics modelling, and decision-making. Studies identified in the initial screening were further screened for their contextual, methodological and application-related relevancy. Studies deemed 'relevant' or 'highly relevant' according to all three criteria were included in this review. Key themes related to the rationale, impact and limitation of using system dynamics in the context of environmental health decision-making and policy were analysed. We identified a limited number of relevant studies (n = 15), two-thirds of which were conducted between 2011 and 2016. The majority of applications occurred in non-health related sectors (n = 9) including transportation, public utilities, water, housing, food, agriculture, and urban and regional planning. Applications were primarily targeted at micro-level (local, community or grassroots) decision-making processes (n = 9), with macro-level (national or international) decision-making to a lesser degree. There was significant heterogeneity in the stated rationales for using system dynamics and the intended impact of the system dynamics model on decision-making processes. A series of user-related, technical and application-related limitations and challenges were identified. None of the reported limitations or challenges appeared unique to the application of system dynamics within the context of environmental health problems, but rather to the use of system dynamics in general. This review reveals that while system dynamics modelling is increasingly being used to inform decision-making related to environmental health, applications are currently limited. Greater application of system dynamics within this context is needed before its benefits and limitations can be fully understood.

Nano/macro porous bioactive glass scaffold

NASA Astrophysics Data System (ADS)

Wang, Shaojie

Bioactive glass (BG) and ceramics have been widely studied and developed as implants to replace hard tissues of the musculo-skeletal system, such as bones and teeth. Recently, instead of using bulk materials, which usually do not degrade rapidly enough and may remain in the human body for a long time, the idea of bioscaffold for tissue regeneration has generated much interest. An ideal bioscaffold is a porous material that would not only provide a three-dimensional structure for the regeneration of natural tissue, but also degrade gradually and, eventually be replaced by the natural tissue completely. Among various material choices the nano-macro dual porous BG appears as the most promising candidate for bioscaffold applications. Here macropores facilitate tissue growth while nanopores control degradation and enhance cell response. The surface area, which controls the degradation of scaffold can also be tuned by changing the nanopore size. However, fabrication of such 3D structure with desirable nano and macro pores has remained challenging. In this dissertation, sol-gel process combined with spinodal decomposition or polymer sponge replication method has been developed to fabricate the nano-macro porous BG scaffolds. Macropores up to 100microm are created by freezing polymer induced spinodal structure through sol-gel transition, while larger macropores (>200um) of predetermined size are obtained by the polymer sponge replication technique. The size of nanopores, which are inherent to the sol-gel method of glass fabrication, has been tailored using several approaches: Before gel point, small nanopores are generated using acid catalyst that leads to weakly-branched polymer-like network. On the other hand, larger nanopores are created with the base-catalyzed gel with highly-branched cluster-like structure. After the gel point, the nanostructure can be further modified by manipulating the sintering temperature and/or the ammonia concentration used in the solvent exchange process. Although both techniques lower the surface area of BG scaffolds, the temperature-dependent sintering process closes nanopores through densification, while the concentration-dependent solvent exchange process enlarges nanopores through Ostwald-ripening type coarsening. Therefore, nanopore size and surface area of BG scaffold are independently controlled using these methods. In vitro cell and in vivo animal tissue responses have been investigated to evaluate the performance of the nano-macro porous BG scaffold. The cells are found to migrate and penetrate deep into the 3D nano-macro porous structure, while exhibiting excellent adhesion to the bioscaffold surface. Importantly, the new tissue with both blood vessels and collagen fibers is formed deep inside the implanted scaffolds without obvious inflammatory reaction. Furthermore, our observations show biological benefits of the nanopores in the BG scaffold. In comparison to BG scaffold without nanopores, cells migrate and penetrate into nano-macro dual-porous BG scaffold faster and deeper mainly because of the increase of surface area. To study the effect of nanopore topography, we fabricated BG scaffolds with the same surface area but different nanopore sizes. It is found that the initial cell attachment is significantly enhanced on the BG scaffold with the same surface area but smaller nanopores size, indicating that the nanopore topography strongly influences the performance of BG scaffold. In conclusion, the present results demonstrate most clearly the usefulness of our nano-macro dual-porous BG as a novel and superior 3D bioscaffold for regenerative medicine and hard tissue engineering.

Policymakers shape implementation and sustainment of evidence-based practices (EBPs), whether they are developing or responding to legislation and policies or negotiating public sector resource constraints. As part of a large mixed-method study, we conducted qualitative interviews with 24 policymakers involved in delivery of the same EBP in two U.S. states. We analyzed transcripts via open and focused coding techniques to identify the commonality, diversity, and complexity of implementation challenges; approaches to overcoming those challenges; and the importance of system-level contextual factors in ensuring successful implementation. Key findings centered on building support and leadership for EBPs; funding and contractual strategies; partnering with stakeholders; tackling challenges via proactive planning and problem solving; and the political, legal, and systemic pressures affecting EBP longevity. The policymaker perspectives offer guidance on nurturing system and organizational practice environments to achieve positive outcomes and for optimally addressing macro-level influences that bear upon the instantiation of EBPs in public sector child welfare systems. © The Author(s) 2014.

Prevention and control of sexually transmitted infections among adolescents: the importance of a socio-ecological perspective--a commentary.

PubMed

DiClemente, R J; Salazar, L F; Crosby, R A; Rosenthal, S L

2005-09-01

The sexually transmitted infection (STI) epidemic among adolescents in the USA is inextricably tied to individual, psychosocial and cultural phenomena. Reconceptualizing the epidemic within an expanded socio-ecological framework may provide an opportunity to better confront its challenges. In this article, we use a socio-ecological framework to identify determinants of adolescents' sexual risk and protective behaviours as well as antecedents of their STI acquisition. The goal is to provide a synthesis of several discrete categories of research. Subsequently, we propose an integrated strategy that addresses the STI epidemic among adolescents by promoting a socio-ecological perspective in both basic research and intervention design. This approach may expand the knowledge base and facilitate the development of a broader array of intervention strategies, such as community-level interventions, policy initiatives, institutionally based programmes, and macro-level societal changes. Although there are inherent challenges associated with such an approach, the end result may have reciprocal and reinforcing effects designed to enhance the adoption and maintenance of STI-preventive practices among adolescents, and further reduce the rate of STIs.

[Care of the chronically ill: strategic challenge, macro-management and health policies].

2014-01-01

The prevalence of chronic diseases is increasing, with the patients who suffer from them having greater need for healthcare. This fact forces a redirection in the health system, currently focused on the acute diseases, to achieve an efficient care. For this reason, it is necessary to work at all levels, starting with political decisions. These decisions should be based on the technical and scientific evidence available. Health planning is essential to establish care strategies, defining the actions to ensure the coordination and continuity of care, and also the redefinition of professional roles, where primary care nurses assume more competencies, becoming key professionals in the care of the chronic patient. The new model should include the professionalization of the management of health services. Information and communication technologies will play an important role in the development of strategies, but considering them as the tools that they are, allowing for the patient to be the focus of attention, and ensuring the privacy and the confidentiality.

From laboratories to chambers of parliament and beyond: producing bioethics in France and Romania.

2013-09-01

In a European context marked by heterogeneous Assisted Reproductive Technology (ART) practices, this article will elucidate and compare the norm elaboration processes pertaining to ART in France and Romania. Using an experimental five-phase model encompassing experimentation, excesses, social mobilization, legislation and contestation, I will examine the processes linking micro (everyday medical practices), meso (institutional regulation) and macro (legislation) levels of ART bioethics in the two countries since the 1980s. ART has developed in France and Romania on different time frames, and Romania's management of ART is decisively influenced by Ceauşescu's pro-natalist policy. However, I will show how the two countries share similar trajectories along the proposed model's first three phases of norm elaboration, and, in recent years, how both have witnessed the emergence of social actors' claims for a more liberal and state-sponsored access to ART, requiring a redefinition of bioethics in line with reproductive social justice at national levels. This is fed by contemporary medical practices and social values, and an increasing transnational interconnectedness between social actors. Copyright © 2013 Elsevier Ltd. All rights reserved.

Social Worker Identity: A Profession in Context.

PubMed

Forenza, Brad; Eckert, Caitlin

2018-01-01

Social work is a broad field encompassing micro, mezzo, and macro areas of practice. Consequently, the field lacks a unifying professional identity due to the expansiveness of the profession. Professional identity is conceptualized as an extension of social identity, vis-à-vis the embodiment of three qualities: connectedness, expansiveness, and effectiveness. This study used 12 in-depth, individual interviews with practicing social workers to explore these qualities. Findings from interviews reveal six primary themes and 21 subthemes pertaining to social worker identity. Themes and subthemes are organized according to three broad families (social work in context, professional trajectories, and external influences). Implications for policy, practice, and future research are presented. © 2017 National Association of Social Workers.

At the intersection of micro and macro: opportunities and challenges for physician-patient communication research.

PubMed

Cline, Rebecca J Welch

2003-05-01

The health care relationship model is undergoing dramatic change. Micro-level communication patterns yield health care relationship models (e.g. paternalism, mutual participation, consumerism). At the same time, macro-level systems appear increasingly likely to influence the nature of micro-level interaction. The intersections of health care communication micro-level and macro-level phenomena provide important venues for research and interventions. This essay identifies theoretical premises regarding the relationships between communication and health-related behavior; explores three prominent and growing macro-level phenomena that observers argue likely influence the physical-patient relationship and communication therein: complementary and alternative medicine, the Internet, and direct-to-consumer advertising of prescription drugs; and offers a research agenda for exploring macro-level influences on micro-level physician-patient communication.

2012-02-21

We report the fabrication of gold screen printed macro electrodes which are electrochemically characterised and contrasted to polycrystalline gold macroelectrodes with their potential analytical application towards the sensing of chromium(III) and (VI) critically explored. It is found that while these gold screen printed macro electrodes have electrode kinetics typically one order of magnitude lower than polycrystalline gold macroelectrodes as is measured via a standard redox probe, in terms of analytical sensing, these gold screen printed macro electrodes mimic polycrystalline gold in terms of their analytical performance towards the sensing of chromium(III) and (VI), whilst boasting additional advantages over the macro electrode due to their disposable one-shot nature and the ease of mass production. An additional advantage of these gold screen printed macro electrodes compared to polycrystalline gold is the alleviation of the requirement to potential cycle the latter to form the required gold oxide which aids in the simplification of the analytical protocol. We demonstrate that gold screen printed macro electrodes allow the low micro-molar sensing of chromium(VI) in aqueous solutions over the range 10 to 1600 μM with a limit of detection (3σ) of 4.4 μM. The feasibility of the analytical protocol is also tested through chromium(VI) detection in environmental samples.

Eugenics concept: from Plato to present.

PubMed

Güvercin, C H; Arda, B

2008-01-01

All prospective studies and purposes to improve cure and create a race that would be exempt of various diseases and disabilities are generally defined as eugenic procedures. They aim to create the "perfect" and "higher" human being by eliminating the "unhealthy" prospective persons. All of the supporting actions taken in order to enable the desired properties are called positive eugenic actions; the elimination of undesired properties are defined as negative eugenics. In addition, if such applications and approaches target the public as a whole, they are defined as macro-eugenics. On the other hand, if they only aim at individuals and/or families, they are called micro-eugenics. As generally acknowledged, Galton re-introduced eugenic proposals, but their roots stretch as far back as Plato. Eugenic thoughts and developments were widely accepted in many different countries beginning with the end of the 19th to the first half of the 20th centuries. Initially, the view of negative eugenics that included compulsory sterilizations of handicapped, diseased and "lower" classes, resulted in tens of thousands being exterminated especially in the period of Nazi Germany. In the 1930s, the type of micro positive eugenics movement found a place within the pro-natalist policies of a number of countries. However, it was unsuccessful since the policy was not able to become effective enough and totally disappeared in the 1960s. It was no longer a fashionable movement and left a deep impression on public opinion after the long years of war. However, developments in genetics and its related fields have now enabled eugenic thoughts to reappear under the spotlight and this is creating new moral dilemmas from an ethical perspective.

To advance understanding of practices that support inclusion of children with intellectual and developmental disabilities in inclusive education classrooms in Africa by conducting a review of the extant literature. Five academic databases were searched supplemented by a hand search of key journals and references of included studies. Two authors independently screened studies via a reference manager (Covidence) which allowed for blinding. A third author was consulted in cases of conflict. Thirty articles that provided empirical evidence of inclusive education implementation were included. Eight articles highlighted practices that support inclusion of children with intellectual and developmental disabilities. Using Bronfenbrenner's bioecological framework, findings revealed that inclusive education implementation is influenced by factors on the bio level, micro level, meso level, and macro level. Recommendations for promoting inclusive education implementation are provided. Inclusion goes beyond teachers and requires strong commitment of other stakeholders such as families and governments. To guarantee the smooth inclusion of children with special education needs and particularly with intellectual and developmental disabilities, a set of practices validated through rigorous research as supportive and unique and that can be universal to Africa is wise. Implications for rehabilitation A number of strategies were identified that can improve the classroom inclusion of children with intellectual and developmental disabilities. Development of policies that support such strategies could improve implementation. Inclusion goes beyond teachers. Rehabilitation professionals (i.e. occupational therapists) and educational professionals should partner to identify practical solutions to the challenges of creating inclusive environments for children with special education needs. Committing more resources and time towards the development and implementation of special education policies can advance the successful inclusion of children with special education needs.

Emigration dynamics from and within South Asia.

Shah, N M

1995-01-01

This review of current knowledge about emigration dynamics from and within South Asia (Bangladesh, India, Pakistan, and Sri Lanka) opens with a brief history of the three phases of emigration from the area since the 1830s (plantation labor; postindependence to the UK, US, Canada, and Australia; and labor migration to the oil-exporting countries). The influence of the creation of Pakistan and Bangladesh is also covered as are British colonial and commonwealth policies. It is noted that migration data are incomplete and that India exhibits an ambivalence about collecting such information. The discussion then turns to emigration since 1970 and considers permanent migration from South Asia to the traditional receivers; South Asian asylum seekers in Europe; South Asian refugees, illegal migrants, migrant workers (flows and destinations), the stock of contract migrant workers (and their characteristics); returnee migrant workers; and skill levels. Analysis is provided of macro level determinants of emigrations such as gross national product (level and growth), the general demographic and social situation, labor force growth and structure, poverty and inequality, and internal and international migration. Environmental factors causing displacement in Southern Asia include floods, cyclones, river bank erosion, drought, and desertification. Global warming could displace millions of people in the region, and development projects have contributed to displacement. The remainder of the report covers political and ethnic factors, micro-factors influencing migration decision-making, the policies of sending and receiving countries, the consequences of emigration, and the potential for migration in the future.

There are many challenges in developing effective and integrated catchment management solutions for hydrology and water quality issues. Such solutions should ideally build on current scientific evidence to inform policy makers and regulators and additionally allow stakeholders to take ownership of local and/or national issues, in effect bringing together ‘communities of practice’. A strategy being piloted in the UK as the Pilot Virtual Observatory (pVO), funded by NERC, is to demonstrate the use of cyber-infrastructure and cloud computing resources to investigate better methods of linking data and models and to demonstrate scenario analysis for research, policy and operational needs. The research will provide new ways the scientific and stakeholder communities come together to exploit current environmental information, knowledge and experience in an open framework. This poster presents the project scope and methodologies for the pVO work dealing with national modelling of hydrology and macro-nutrient biogeochemistry. We evaluate the strategies needed to robustly benchmark our current predictive capability of these resources through ensemble modelling. We explore the use of catchment similarity concepts to understand if national monitoring programs can inform us about the behaviour of catchments. We discuss the challenges to applying these strategies in an open access and integrated framework and finally we consider the future for such virtual observatory platforms for improving the way we iteratively improve our understanding of catchment science.

Service user involvement in health and social care is a key policy driver in the UK. In cancer care it is central to developing services which are effective, responsive and accessible to patients. Cancer network partnership groups are set up to enable joint working between service users and health care professionals and to drive service improvements. The aim of this study was to explore the influence of the cancer network partnership groups' service user involvement activities on cancer care. This was a qualitative study involving documentary analysis and in-depth case studies of a sample of partnership groups. Five partnership groups were purposively selected as case studies from Macmillan regions across the UK; documents were collated from a further five groups. Forty people, including core group members and key stakeholders in cancer services, were interviewed. The evidence from this study suggests that cancer network partnership groups are at their most influential at 'grass roots' level - contributing to patient information resources, enhancing access to services, and improving care environments. While such improvements are undoubtedly important to patients, the groups' aim is to influence strategic changes, for example in cancer care commissioning or macro-level policy decision-making. The evolution of open, participatory relationships between service users and professionals, and recognition of the value of experiential knowledge are seen as key factors in influencing cancer care. The provision of dedicated resources to strengthen service user involvement activities is also vital. © 2010 Blackwell Publishing Ltd.

Ocean litter has accumulated rapidly and is becoming a major environmental concern, yet quantitative and regular observations and exploration that track litter origins are limited. By implementing monthly sample collections over five years (2012–2016) at Dongsha Island, a remote island in the northern South China Sea (SCS), we assessed macro ocean litter dynamics, identified source countries of individual plastic bottles, and analyzed the origins of the litter by a backward-tracking model simulation considering both the effects of current velocity and windage. The results showed that large amounts of litter, which varied monthly and annually in weight and quantity, reached the island during the study years, and there were spatial differences in accumulation patterns between the north and south coasts. Styrofoam and plastic bottles were the two primary sources of macro ocean litter both annually and monthly, and most of the litter collected on the island originated from China and Vietnam, which were collectively responsible for approximately 47.5%–63.7% per month. The simulation indicated that current advection at the near-surface depths and low windage at the sea surface showed similar patterns, while medium to high windage exhibited comparable expression patterns in response to potential source regions and drifting time experiments. At either the surface with low windage or current advection at depths of 0.5 m and 1 m, macro ocean litter in the Western Philippine Sea, i.e. through the Luzon Strait between Taiwan and the Philippines, was an important contributor to the litter bulk from October to March, whereas the litter was predicted to mainly originate from the southwestern SCS from April to September. With an increasing windage effect, litter in the Taiwan Strait was predicted to be an additional major potential source. Surprisingly, a small proportion of the macro ocean litter was predicted to continuously travel in the northern SCS for a long duration (> 2 years) before drifting onto Dongsha Island. The estimated drifting time of macro ocean litter also showed monthly and directional variability. This study demonstrated that a tremendous quantity of macro ocean litter, which may cause great damage to the marine ecosystem, drifts in the ocean surface layer and is finally pushed onto beaches. Therefore, we proposed an action plan for effective ocean litter management development at regional and global spatial scales, which is vital for improving and restoring the health and sustainability of the oceanic environment.

The temperature size rule in arthropods: independent of macro-environmental variables but size dependent.

PubMed

Klok, C Jaco; Harrison, Jon F

2013-10-01

Temperature is a key factor that affects the rates of growth and development in animals, which ultimately determine body size. Although not universal, a widely documented and poorly understood pattern is the inverse relationship between the temperature at which an ectothermic animal is reared and its body size (temperature size rule [TSR]). The proximate and ultimate mechanisms for the TSR remain unclear. To explore possible explanations for the TSR, we tested for correlations between the magnitude/direction of the TSR and latitude, temperature, elevation, habitat, availability of oxygen, capacity for flight, and taxonomic grouping in 98 species/populations of arthropods. The magnitude and direction of the TSR was not correlated with any of the macro-environmental variables we examined, supporting the generality of the TSR. However, body size affected the magnitude and direction of the TSR, with smaller arthropods more likely to demonstrate a classic TSR. Considerable variation among species exists in the TSR, suggesting either strong interactions with nutrition, or selection based on microclimatic or seasonal variation not captured in classic macro-environmental variables.

Landsat-TM (Theme Mapper) and EOS (Earth Observing System)-MODIS (MODerate resolution Imaging Spectrora-diometer) Terra/Aqua images were used to monitor the macro-algae (Ulva prolifera) bloom since 2007 at the Yellow Sea and the East China Sea. At the turbid waters of Northern Jiangsu Shoal, there is strong spectral mixing behavior, and satellite images with finer spatical resolution are more effective in detection of macro-algae patches. Macro-algae patches were detected by the Landsat images for the first time at the Sheyang estuary where is dominated by very turbid waters. The MODIS images showed that the macro-algae from the turbid waters near the Northern Jiangsu Shoal drifted southwardly in the early of May and affected the East China Sea waters; with the strengthening east-asian Summer Monsoon, macro-algae patches mainly drifted in a northward path which was mostly observed at the Yellow Sea. Macro-algae patches were also found to drift eastwardly towards the Korea Peninsular, which are supposed to be driven by the sea surface wind.

Estimating drought risk across Europe from reported drought impacts, hazard indicators and vulnerability factors

Drought is one of the most costly natural hazards in Europe. Due to its complexity, drought risk, the combination of the natural hazard and societal vulnerability, is difficult to define and challenging to detect and predict, as the impacts of drought are very diverse, covering the breadth of socioeconomic and environmental systems. Pan-European maps of drought risk could inform the elaboration of guidelines and policies to address its documented severity and impact across borders. This work (1) tests the capability of commonly applied hazard indicators and vulnerability factors to predict annual drought impact occurrence for different sectors and macro regions in Europe and (2) combines information on past drought impacts, drought hazard indicators, and vulnerability factors into estimates of drought risk at the pan-European scale. This "hybrid approach" bridges the gap between traditional vulnerability assessment and probabilistic impact forecast in a statistical modelling framework. Multivariable logistic regression was applied to predict the likelihood of impact occurrence on an annual basis for particular impact categories and European macro regions. The results indicate sector- and macro region specific sensitivities of hazard indicators, with the Standardised Precipitation Evapotranspiration Index for a twelve month aggregation period (SPEI-12) as the overall best hazard predictor. Vulnerability factors have only limited ability to predict drought impacts as single predictor, with information about landuse and water resources as best vulnerability-based predictors. (3) The application of the "hybrid approach" revealed strong regional (NUTS combo level) and sector specific differences in drought risk across Europe. The majority of best predictor combinations rely on a combination of SPEI for shorter and longer aggregation periods, and a combination of information on landuse and water resources. The added value of integrating regional vulnerability information with drought risk prediction could be proven. Thus, the study contributes to the overall understanding of drivers of drought impacts, current practice of drought indicators selection for specific application, and drought risk assessment.

Background HIV infection rates are increasing among marginalized women in Ontario, Canada. HIV-related stigma, a principal factor contributing to the global HIV epidemic, interacts with structural inequities such as racism, sexism, and homophobia. The study objective was to explore experiences of stigma and coping strategies among HIV-positive women in Ontario, Canada. Methods and Findings We conducted a community-based qualitative investigation using focus groups to understand experiences of stigma and discrimination and coping methods among HIV-positive women from marginalized communities. We conducted 15 focus groups with HIV-positive women in five cities across Ontario, Canada. Data were analyzed using thematic analysis to enhance understanding of the lived experiences of diverse HIV-positive women. Focus group participants (n = 104; mean age = 38 years; 69% ethnic minority; 23% lesbian/bisexual; 22% transgender) described stigma/discrimination and coping across micro (intra/interpersonal), meso (social/community), and macro (organizational/political) realms. Participants across focus groups attributed experiences of stigma and discrimination to: HIV-related stigma, sexism and gender discrimination, racism, homophobia and transphobia, and involvement in sex work. Coping strategies included resilience (micro), social networks and support groups (meso), and challenging stigma (macro). Conclusions HIV-positive women described interdependent and mutually constitutive relationships between marginalized social identities and inequities such as HIV-related stigma, sexism, racism, and homo/transphobia. These overlapping, multilevel forms of stigma and discrimination are representative of an intersectional model of stigma and discrimination. The present findings also suggest that micro, meso, and macro level factors simultaneously present barriers to health and well being—as well as opportunities for coping—in HIV-positive women's lives. Understanding the deleterious effects of stigma and discrimination on HIV risk, mental health, and access to care among HIV-positive women can inform health care provision, stigma reduction interventions, and public health policy.

Objectives BRIGHTLIGHT is a national evaluation of cancer services for teenagers and young adults in England. Following challenges with recruitment, our aim was to understand more fully healthcare professionals’ perspectives of the challenges of recruiting young people to a low-risk observational study, and to provide guidance for future recruitment processes. Design Qualitative. Setting National Health Service (NHS) hospitals in England. Methods Semistructured telephone interviews with a convenience sample of 23 healthcare professionals. Participants included principal investigators/other staff recruiting into the BRIGHTLIGHT study. Data were analysed using framework analysis. Results The emergent themes were linked to levels of research organisational management, described using the levels of social network analysis: micro-level (the individual; in this case the target population to be recruited—young people with cancer); meso-level (the organisation; refers to place of recruitment and people responsible for recruitment); and macro-level (the large-scale or global structure; refers to the wider research function of the NHS and associated policies). Study-related issues occurred across all three levels, which were influenced by the context of the study. At the meso-level, professionals’ perceptions of young people and communication between professionals generated age/cancer type silos, resulting in recruitment of either children or adults, but not both by the same team, and only in the cancer type the recruiting professional was aligned to. At the macro-level the main barrier was discordant configuration of a research service with a clinical service. Conclusions This study has identified significant barriers to recruitment mainly at the meso-level and macro-level, which are more challenging for research teams to influence. We suggest that interconnected whole-system changes are required to facilitate the success of interventions designed to improve recruitment. Interventions targeted at study design/management and the micro-level only may be less successful. We offer solutions to be considered by those involved at all levels of research for this population.

macroH2A is an H2A variant with a highly unusual structural organization. It has a C-terminal domain connected to the N-terminal histone domain by a linker. Crystallographic and biochemical studies show that changes in the L1 loop in the histone fold region of macroH2A impact the structure and potentially the function of nucleosomes. The 1.6-Å X-ray structure of the nonhistone region reveals an α/β fold which has previously been found in a functionally diverse group of proteins. This region associates with histone deacetylases and affects the acetylation status of nucleosomes containing macroH2A. Thus, the unusual domain structure of macroH2A integrates independent functions that are instrumental in establishing a structurally and functionally unique chromatin domain. PMID:16107708

The health sector in Québec (Canada) is dealing with profound macro-economic and macro-organizational changes. This article is interested in the impact of these changes on the work of home health aides (HHAs) and home care nurses and their occupational health and safety (OHS). The study was carried out in the home care services (HCS) of four local community service centres (CLSC) with different organizational characteristics. It is based on an analysis by triangulation of 66 individual and group interviews, 22 observed workdays and 35 observed multidisciplinary or professional meetings, as well as on administrative documents. HHAs are experiencing an erosion of their job because the relational and affective aspects of their work are disappearing. This may be due to an increase in their physical workload, leading to an increase in musculoskeletal problems and, to a lesser extent, in psychological health problems. Nurses are seeing an increase in the volume of invisible work that they have to do, which also has the effect of decreasing the relational aspects of their activity. The increasingly numerous psychological health problems are the consequence of this change in their profession. This study also shows that managers' decisions at the local level can reduce or increase the work constraints of HHAs and nurses. Examples of good practices for HHAs are the stabilization of clienteles and the possibility of organizing their itinerary, while for nurses, it is in how clientele follow-up tools are implemented. This article discusses the effects of government policies and decisions on the work and OHS of home care personnel. To address this subject, we use a specific analysis of the workload of home health aides (HHAs) and nurses. We will show the relationships between managers' organizational choices to respond to governmental constraints and the resulting work changes. We will also look at their consequences on occupational health and safety (OHS) and on the work of different personnel.

Background: Inequality in households’ and individuals' consumption expenditures is one of the most important aspects of health status difference among households and individuals. Objectives: We investigated the impact of some macro-economic factors specially inequality factors on the Iranian rural health status since 1986 through 2012. Patients and Methods: We conducted a longitudinal ecological and analytical study. The average sample size was 14602 households whom Iranian Statistics Center selected by a multi-stages clustering sampling approach. All required data has been collected from Iranian Statistics Centre and Deputy for Curial Affaires of Iranian Ministry of Health. We calculated the Gini coefficients for the rural food and health expenditures, then conducted a transloge autoregressive order one (AR1) to investigate the association between the Iranian rural households' key mortality rates and the food and health expenditure Gini coefficients, time trend, GDP per capita (PPP), and GDP per capita Gini coefficients. Results: The mean of Gini coefficients were 0.137 and 0.21 for the rural food expenditures inequality based on current and constant price, respectively. In addition, the mean of Gini coefficients were 0.26 and 0.31 for the rural health expenditures inequality based on current and constant price, respectively. The time trend, transloged form of Gini coefficients for health expenditures and GDP per capita Gini coefficients presented a significant negative correlation with transloged form of neonatal mortality rate. With regard to the transloged form of under five mortality we observed a significant negative correlation with time trend and transloged form of Gini coefficients for health expenditure and GDP per capita. Finally, there was a significant negative correlation between transloged forms of maternal mortality rate. Conclusions: Iranian policy makers should consider the rural health and food expenditures inequality and try to adopt more effective policies and plans to decrease it. In addition, they should improve the macro-economic factors to improve the rural households' health status. PMID:24829771

Mentat, an object-oriented macro data flow system designed to facilitate parallelism in distributed systems, is presented. The macro data flow model is a model of computation similar to the data flow model with two principal differences: the computational complexity of the actors is much greater than in traditional data flow systems, and there are persistent actors that maintain state information between executions. Mentat is a system that combines the object-oriented programming paradigm and the macro data flow model of computation. Mentat programs use a dynamic structure called a future list to represent the future of computations.
