    A new political economy of conflict has emerged in the aftermath of colonialism and the Cold War. Complex political emergencies have been simmering in the post-colonial world for more than three decades. Intra-country armed conflict, often combined with natural disasters, at present contributes to the displacement of over 20 million people world-wide. The international community remains profoundly uncomfortable with the complex political emergencies of the new era, torn between the respect for national sovereignty upon which the international political system of the United Nations and other agencies is built, and the growth of concern with human rights and a burgeoning International Humanitarian Law. Globalisation may have brought many benefits to some but there are also many losers. The Word Bank and the International Monetary Fund imposed structural adjustment policies to ensure debt repayment and economic restructuring that have resulted in a net reduction in expenditure on health, education and development. A downward spiral has been created of debt, disease, malnutrition, missed education, economic entrapment, poverty, powerlessness, marginalization, migration and instability. Africa's complex political emergencies are particularly virulent and tenacious. Three examples that are among the most serious humanitarian emergencies to have faced the world in recent times--those in Angola, the Democratic Republic of Congo and Sudan--are reviewed here in detail. The political evolution of these emergencies and their impact on the health of the affected populations are also explored.

    Complex humanitarian emergencies include the relatively acute, severe, and overwhelming health consequences of armed conflict, food scarcity, mass displacement, and political strife. Neurological manifestations of complex humanitarian emergencies are important and underappreciated consequences of emergencies in populations worldwide. This review critically assesses the existing knowledge of the range of neurological disorders that accompany complex humanitarian emergencies and natural disasters in both the acute phase of crisis and the "long shadow" that follows.

    Women and children bear the greatest burden in the midst of war and long-term disasters. Complex humanitarian emergencies are characterized by social disruption, armed conflict, population displacement, collapse of public health infrastructure, and food shortages. Humanitarian assistance for refugees and internally displaced populations requires particular attention to the common issues affecting morbidity and mortality in women and infants. Gender-based violence and reproductive health concerns are discussed within the context of populations affected by conflict and forced migration. Recommendations for midwives and women's health care providers engaging in care for women and children in complex humanitarian emergencies are discussed.

  4. Neonatal survival in complex humanitarian emergencies: setting an evidence-based research agenda

    PubMed Central

    2014-01-01

    Background Over 40% of all deaths among children under 5 are neonatal deaths (0–28 days), and this proportion is increasing. In 2012, 2.9 million newborns died, with 99% occurring in low- and middle-income countries. Many of the countries with the highest neonatal mortality rates globally are currently or have recently been affected by complex humanitarian emergencies. Despite the global burden of neonatal morbidity and mortality and risks inherent in complex emergency situations, research investments are not commensurate to burden and little is known about the epidemiology or best practices for neonatal survival in these settings. Methods We used the Child Health and Nutrition Research Initiative (CHNRI) methodology to prioritize research questions on neonatal health in complex humanitarian emergencies. Experts evaluated 35 questions using four criteria (answerability, feasibility, relevance, equity) with three subcomponents per criterion. Using SAS 9.2, a research prioritization score (RPS) and average expert agreement score (AEA) were calculated for each question. Results Twenty-eight experts evaluated all 35 questions. RPS ranged from 0.846 to 0.679 and the AEA ranged from 0.667 to 0.411. The top ten research priorities covered a range of issues but generally fell into two categories– epidemiologic and programmatic components of neonatal health. The highest ranked question in this survey was “What strategies are effective in increasing demand for, and use of skilled attendance?” Conclusions In this study, a diverse group of experts used the CHRNI methodology to systematically identify and determine research priorities for neonatal health and survival in complex humanitarian emergencies. The priorities included the need to better understand the magnitude of the disease burden and interventions to improve neonatal health in complex humanitarian emergencies. The findings from this study will provide guidance to researchers and program implementers in

    Introduction: Volunteers and members of relief organizations increasingly seek formal training prior to international field deployment. This paper identifies training programs for personnel responding to international disasters and complex humanitarian emergencies, and provides concise information – if available- regarding the founding organization, year established, location, cost, duration of training, participants targeted, and the content of each program. Methods: An environmental scan was conducted through a combination of a peer-reviewed literature search and an open Internet search for the training programs. Literature search engines included EMBASE, Cochrane, Scopus, PubMed, Web of Science databases using the search terms “international,” “disaster,” “complex humanitarian emergencies,” “training,” and “humanitarian response”. Both searches were conducted between January 2, 2013 and September 12, 2013. Results: 14 peer-reviewed articles mentioned or described eight training programs, while open Internet search revealed 13 additional programs. In total, twenty-one training programs were identified as currently available for responders to international disasters and CHE. Each of the programs identified has different goals and objectives, duration, expenses, targeted trainees and modules. Each of the programs identified has different goals and objectives, duration, expenses, targeted trainees and modules. Seven programs (33%) are free of charge and four programs (19%) focus on the mental aspects of disasters. The mean duration for each training program is 5 to 7 days. Fourteen of the trainings are conducted in multiple locations (66%), two in Cuba (9%) and two in Australia (9%). The cost-reported in US dollars- ranges from $100 to $2,400 with a mean cost of $480 and a median cost of $135. Most of the programs are open to the public, but some are only available by invitation only, such as the International Mobilization Preparation for

    In a complex humanitarian emergency, a catastrophic breakdown of political, economic, and social systems, often accompanied by violence, contributes to a long-lasting dependency of the affected communities on external service. Relief systems, such as the Emergency Response Units of the International Federation of Red Cross and Red Crescent Societies, have served as a sound foundation for fieldwork in humanitarian emergencies. The experience in emergencies gained in Rwanda in 1994 and Kosovo in 1999 clearly points to the need for individual adjustments of therapeutic standards to preexisting morbidity and health care levels within the affected population. In complex emergencies, public health activities have been shown to promote peace, prevent violence, and reconcile enemies. A truly democratic and multi-professional approach in all public health training for domestic or foreign service serves as good pattern for fieldwork. Beyond the technical and scientific skills required in the profession, political, ethical, and communicative competencies are critical in humanitarian assistance. Because of the manifold imperatives of further public health education for emergency assistance, a humanitarian assistance competence training center should be established. Competence training centers focus on the core competencies required to meet future needs, are client-oriented, connect regional and international networks, rely on their own system of quality control, and maintain a cooperative management of knowledge. Public health focusing on complex humanitarian emergencies will have to act in prevention not only of diseases and impairments but also of political tension and hatred.

    On January 12, 2010, a 7.0-magnitude earthquake struck Haiti. The event disrupted infrastructure and was marked by extreme morbidity and mortality. The global response to the disaster was rapid and immense, comprising multiple actors-including academic health centers (AHCs)-that provided assistance in the field and from home. The authors retrospectively examine the multidisciplinary approach that the University of Chicago Medicine (UCM) applied to postearthquake Haiti, which included the application of institutional structure and strategy, systematic deployment of teams tailored to evolving needs, and the actual response and recovery. The university mobilized significant human and material resources for deployment within 48 hours and sustained the effort for over four months. In partnership with international and local nongovernmental organizations as well as other AHCs, the UCM operated one of the largest and more efficient acute field hospitals in the country. The UCM's efforts in postearthquake Haiti provide insight into the role AHCs can play, including their strengths and limitations, in complex disasters. AHCs can provide necessary intellectual and material resources as well as technical expertise, but the cost and speed required for responding to an emergency, and ongoing domestic responsibilities, may limit the response of a large university and hospital system. The authors describe the strong institutional backing, the detailed predeployment planning and logistical support UCM provided, the engagement of faculty and staff who had previous experience in complex humanitarian emergencies, and the help of volunteers fluent in the local language which, together, made UCM's mission in postearthquake Haiti successful.

    Importance: Refugees and internally displaced persons are highly vulnerable to sexual violence during conflict and subsequent displacement. However, accurate estimates of the prevalence of sexual violence among in these populations remain uncertain. Objective: Our objective was to estimate the prevalence of sexual violence among refugees and displaced persons in complex humanitarian emergencies. Data Source: We conducted systematic review of relevant literature in multiple databases (EMBASE, CINAHL, and MEDLINE) through February 2013 to identify studies. We also reviewed reference lists of included articles to identify any missing sources. Study Selection: Inclusion criteria required identification of sexual violence among refugees and internally displaced persons or those displaced by conflict in complex humanitarian settings. Studies were excluded if they did not provide female sexual violence prevalence, or that included only single case reports, anecdotes, and those that focused on displacement associated with natural disasters. After a review of 1175 citations 19 unique studies were selected. Data Extraction: Two reviewers worked independently to identify final selection and a third reviewer adjudicated any differences. Descriptive and quantitative information was extracted; prevalence estimates were synthesized. Heterogeneity was assessed using I2. Main Outcomes: The main outcome of interest was sexual violence among female refugees and internally displaced persons in complex humanitarian settings. Results: The prevalence of sexual violence was estimated at 21.4% (95% CI, 14.9-28.7; I2=98.3%), using a random effects model. Statistical heterogeneity was noted with studies using probability sampling designs reporting lower prevalence of sexual violence (21.0%, 95% CI, 13.2-30.1; I2=98.6%), compared to lower quality studies (21.7%, 95% CI, 11.5-34.2; I2=97.4%). We could not rule out the presence of publication bias. Conclusions: The findings suggest that

    Background: Complex Humanitarian Emergencies (CHE) result in rapid degradation of population health and quickly overwhelm indigenous health resources. Numerous governmental, non-governmental, national and international organizations and agencies are involved in the assessment of post-CHE affected populations. To date, there is no entirely quantitative assessment tool conceptualized to measure the public health impact of CHE. Methods: Essential public health parameters in CHE were identified based on the Sphere Project "Minimum Standards", and scoring rubrics were proposed based on the prevailing evidence when applicable. Results: 12 quantitative parameters were identified, representing the four categories of “Minimum Standards for Disaster Response” according to the Sphere Project; health, shelter, food and nutrition, in addition to water and sanitation. The cumulative tool constitutes a quantitative scale, referred to as the Public Health Impact Severity Scale (PHISS), and the score on this scale ranges from a minimum of 0 to a maximum of 100. Conclusion: Quantitative measurement of the public health impact of CHE is germane to accurate assessment, in order to identify the scale and scope of the critical response required for the relief efforts of the affected populations. PHISS is a new conceptual metric tool, proposed to add an objective quantitative dimension to the post-CHE assessment arsenal. PHISS has not yet been validated, and studies are needed with prospective data collection to test its validity, feasibility and reliability. Citation: Bayram JD, Kysia R, Kirsch TD.

    Health information systems (HIS) in emergencies face a double dilemma: the information necessary to understand and respond to humanitarian crises must be timely and detailed, whereas the circumstances of these crises makes it challenging to collect it. Building on the technical work of the Health Metrics Network on HIS and starting with a systemic definition of HIS in emergencies, this paper reviews the various data-collection platforms in these contexts, looking at their respective contributions to providing what humanitarian actors need to know to target their intervention to where the needs really are. Although reporting or sampling errors are unavoidable, it is important to identify them and acknowledge the limitations inherent in generalizing data that were collected in highly heterogeneous environments. To perform well in emergencies, HIS require integration and participation. In spite of notable efforts to coordinate data collection and dissemination practices among humanitarian agencies, it is noted that coordination on the ground depends on the strengths and presence of a lead agency, often WHO, and on the commitment of humanitarian agencies to investing resources in data production. Poorly integrated HIS generate fragmented, incomplete and often contradictory statistics, a situation that leads to a misuse of numbers with negative consequences on humanitarian interventions.

    The objective of this report was to show how the Center for Humanitarian Emergencies (the Center) at Emory University (Atlanta, Georgia USA) has trained graduate students to respond to complex humanitarian emergencies (CHEs) through innovative educational programs, with the goal of increasing the number of trained humanitarian workers. Natural disasters are on the rise with more than twice as many occurring from 2000-2009 as there were from 1980-1989. In 2012 alone, 144 million people were affected by a natural disaster or displaced by conflict worldwide. This has created an immense need for trained humanitarian workers to respond effectively to such disasters. The Center has developed a model for educational programming that targets learners along an educational continuum ranging from the undergraduate level through continuing professional education. These programs, based in the Rollins School of Public Health (RSPH) of Emory University, include: a competency-based graduate certificate program (the Certificate) in humanitarian emergencies; a fellowship program for mid-career professionals; and funded field practica. The competency-based Certificate program began in 2010 with a cohort of 14 students. Since then, 101 students have received the Certificate with 50 more due for completion in 2016 and 2017 combined. The fellowship program for mid-career professionals has hosted four fellows from conflict-affected or resource-poor countries, who have then gone on to assume leadership positions with humanitarian organizations. From 2009-2015, the field practicum program supported 34 students in international summer practicum experiences related to emergency response or preparedness. Students have participated in summer field experiences on every continent but Australia. Together the Certificate, funded field practicum opportunities, and the fellowship comprise current efforts in providing innovative education and training for graduate and post-graduate students of public

    Surveys are conducted frequently in humanitarian emergencies to assess the health status of the population. Most often, they employ complex sample designs, such as cluster sampling. Mortality is an indicator commonly estimated in such surveys. Confidence limits provide information on the precision of the estimate and it is important to ensure that confidence limits for a mortality rate account for the survey design and utilise an acceptable methodology. This paper describes the calculation of confidence limits for mortality rates from surveys using complex sampling designs and a variety of software programmes and methods. It contains an example that makes use of the SAS, SPSS, and Epi Info software programmes. Of the three confidence interval methods examined--the ratio command approach, the modified rate approach, and the modified proportion approach--the paper recommends the ratio command approach to estimate mortality rates with confidence limits.

  17. Health equity in humanitarian emergencies: a role for evidence aid.

    PubMed

    Pottie, Kevin

    2015-02-01

    Humanitarian emergencies require a range of planned and coordinated actions: security, healthcare, and, as this article highlights, health equity responses. Health equity is an evidence-based science that aims to address unfair and unjust health inequality outcomes. New approaches are using health equity to guide the development of community programs, equity methods are being used to identify disadvantaged groups that may face health inequities in a humanitarian emergency, and equity is being used to prevent unintended harms and consequences in interventions. Limitations to health equity approaches include acquiring sufficient data to make equity interpretations, integrating disadvantage populations in to the equity approach, and ensuring buy-in from decision-makers. This article uses examples from World Health Organization, Refugee Health Guidelines and Health Impact Assessment to demonstrate the emerging role for health equity in humanitarian emergencies. It is based on a presentation at the Evidence Aid Symposium, on 20 September 2014, at Hyderabad, India.

    The provision of surgery within humanitarian crises is complex, requiring coordination and cooperation among all stakeholders. During the 2011 Humanitarian Action Summit best practice guidelines were proposed to provide greater accountability and standardization in surgical humanitarian relief efforts. Surgical humanitarian relief planning should occur early and include team selection and preparation, appropriate disaster-specific anticipatory planning, needs assessment, and an awareness of local resources and limitations of cross-cultural project management. Accurate medical record keeping and timely follow-up is important for a transient surgical population. Integration with local health systems is essential and will help facilitate longer term surgical health system strengthening.

    Humanitarian emergencies result in a breakdown of critical health-care services and often make vulnerable communities dependent on external agencies for care. In resource-constrained settings, this may occur against a backdrop of extreme poverty, malnutrition, insecurity, low literacy and poor infrastructure. Under these circumstances, providing food, water and shelter and limiting communicable disease outbreaks become primary concerns. Where effective and safe vaccines are available to mitigate the risk of disease outbreaks, their potential deployment is a key consideration in meeting emergency health needs. Ethical considerations are crucial when deciding on vaccine deployment. Allocation of vaccines in short supply, target groups, delivery strategies, surveillance and research during acute humanitarian emergencies all involve ethical considerations that often arise from the tension between individual and common good. The authors lay out the ethical issues that policy-makers need to bear in mind when considering the deployment of mass vaccination during humanitarian emergencies, including beneficence (duty of care and the rule of rescue), non-maleficence, autonomy and consent, and distributive and procedural justice.

    2003-03-01

    Natural and man-made emergencies are regular occurrences in the Greater Horn of Africa region. The underlying impoverishment of whole populations is increasing, making it more difficult to distinguish between humanitarian crises triggered by shocks and those resulting from chronic poverty. Shocks and hazards can no longer be seen as one-off events that trigger a one-time response. In countries that are both poor and exposed to frequent episodes of debilitating drought or chronic conflict, information needs tend to be different from the straightforward early warning/commodity accounting models of information systems that have proven reliable in past emergencies. This paper describes the interdependent components of a humanitarian information system appropriate for this kind of complex environment, noting the analytical links between the components and operational links to programme and policy. By examining a series of case studies from the Greater Horn region, the paper demonstrates that systems lacking one or more of these components will fail to provide adequate information--and thus incur humanitarian costs. While information always comes with a cost, the price of poor information--or none--is higher. And in situations of chronic vulnerability, in which development interventions are likely to be interspersed with both safety nets and emergency interventions on a recurrent basis, investment in improved information is a good investment from both a humanitarian and a financial viewpoint.

    Humanitarian emergencies may result in breakdown of regular health services including routine vaccination programs. Displaced populations including refugees and internally displaced persons are particularly susceptible to outbreaks of communicable diseases such as vaccine-preventable diseases (VPDs). Common VPDs encountered in humanitarian emergencies include measles, polio, and depending on geographical location, meningococcal meningitis, yellow fever, hepatitis A, and cholera. We conducted a review of 50 published articles from 2000 to 2015 concerning VPDs in humanitarian emergencies. This article provides an update on the available literature regarding vaccinations among this highly vulnerable population and describes the unique challenges of VPDs during humanitarian emergencies. Humanitarian emergencies place affected populations at risk for elevated morbidity and mortality from VPDs due to creation or exacerbation of factors associated with disease transmission such as mass population movements, overcrowding, malnutrition, and poor water and sanitation conditions. Vaccination is one of the most basic and critical health interventions for protecting vulnerable populations during emergencies. Growing insecurity, as seen in the increasing number of targeted attacks on health workers in recent years, as well as destruction of cold chain and infrastructure for transportation of supplies, are creating new challenges in provision of life saving vaccines in conflict settings. Population displacement can also threaten global VPD eradication and elimination efforts. While highly effective vaccines and guidelines to combat VPDs are available, the trend of increasing number of humanitarian emergencies globally poses new and emerging challenges in providing vaccination among displaced populations.

    Research is needed to make responses to disasters and humanitarian emergencies more evidence-based. Such research must also adhere to the generally accepted principles of research ethics. While research into health interventions used in disasters raises distinctive ethical concerns, seven ethical principles developed for clinical research are applied here to disaster research. Practical examples from disaster settings are used to demonstrate how these ethical principles can be applied. This reveals that research ethics needs to be seen as much more than a mechanism to obtain ethical approval for research. Research ethics involves ethical principles and governance frameworks, but must also consider the role of ethical virtues in research. Virtues are essential to ensure that researchers do what they believe is ethically right and resist what is unethical. Research ethics that truly protects participants and promotes respect needs to include training in ethical virtues to ensure disaster research is carried out to the highest ethical standards. This article is based on a presentation at the Evidence Aid Symposium on 20 September 2014, in Hyderabad, India.

    Abstract Objective To describe tools used for the assessment of maternal and child health issues in humanitarian emergency settings. Methods We systematically searched MEDLINE, Web of Knowledge and POPLINE databases for studies published between January 2000 and June 2014. We also searched the websites of organizations active in humanitarian emergencies. We included studies reporting the development or use of data collection tools concerning the health of women and children in humanitarian emergencies. We used narrative synthesis to summarize the studies. Findings We identified 100 studies: 80 reported on conflict situations and 20 followed natural disasters. Most studies (76/100) focused on the health status of the affected population while 24 focused on the availability and coverage of health services. Of 17 different data collection tools identified, 14 focused on sexual and reproductive health, nine concerned maternal, newborn and child health and four were used to collect information on sexual or gender-based violence. Sixty-nine studies were done for monitoring and evaluation purposes, 18 for advocacy, seven for operational research and six for needs assessment. Conclusion Practical and effective means of data collection are needed to inform life-saving actions in humanitarian emergencies. There are a wide variety of tools available, not all of which have been used in the field. A simplified, standardized tool should be developed for assessment of health issues in the early stages of humanitarian emergencies. A cluster approach is recommended, in partnership with operational researchers and humanitarian agencies, coordinated by the World Health Organization. PMID:26478629

  4. Neonatal survival interventions in humanitarian emergencies: a survey of current practices and programs

    PubMed Central

    2012-01-01

    Background Neonatal deaths account for over 40% of all deaths in children younger than five years of age and neonatal mortality rates are highest in areas affected by humanitarian emergencies. Of the ten countries with the highest neonatal mortality rates globally, six are currently or recently affected by a humanitarian emergency. Yet, little is known about newborn care in crisis settings. Understanding current policies and practices for the care of newborns used by humanitarian aid organizations will inform efforts to improve care in these challenging settings. Methods Between August 18 and September 25, 2009, 56 respondents that work in humanitarian emergencies completed a web-based survey either in English or French. A snow ball sampling technique was used to identify organizations that provide health services during humanitarian emergencies to gather information on current practices for maternal and newborn care in these settings. Information was collected about continuum-of-care services for maternal, newborn and child health, referral services, training and capacity development, health information systems, policies and guidelines, and organizational priorities. Data were entered into MS Excel and frequencies and percentages were calculated. Results The majority of responding organizations reported implementing components of neonatal and maternal health interventions. However, multiple barriers exist in providing comprehensive care, including: funding shortages (63.3%), gaps in training (51.0%) and staff shortages and turnover (44.9%). Conclusions Neonatal care is provided by most of the responding humanitarian organizations; however, the quality, breadth and consistency of this care are limited. PMID:22824461

    Objectives. We developed the Humanitarian Emergency Settings Perceived Needs (HESPER) Scale, a valid and reliable scale to rapidly assess perceived needs of populations in humanitarian settings in low- and middle-income countries. Methods. We generated items through a literature review; reduced the number of items on the basis of a survey with humanitarian experts; pilot-tested the scale in Gaza, Jordan, Sudan, and the United Kingdom; and field-tested it in Haiti, Jordan, and Nepal. Results. During field-testing, intraclass correlation coefficients (absolute agreement) for the total number of unmet needs were 0.998 in Jordan, 0.986 in Haiti, and 0.995 in Nepal (interrater reliability), and 0.961 in Jordan and 0.773 in Nepal (test–retest reliability). Cohen’s κ for the 26 individual HESPER items ranged between 0.66 and 1.0 (interrater reliability) and between 0.07 and 1.0 (test–retest reliability) across sites. Most HESPER items correlated as predicted with related questions of the World Health Organization Quality of Life-100 (WHOQOL-100), and participants found items comprehensive and relevant, suggesting criterion (concurrent) validity and content validity. Conclusions. The HESPER Scale rapidly provides valid and reliable population-based data on perceived needs in humanitarian settings. PMID:22897533

    Armed conflicts and natural disasters impact negatively on the mental health and well-being of affected populations in the short- and long-term and affect the care of people with pre-existing mental health conditions. This paper outlines specific actions for mental health and psychosocial support by the health sector in the preparedness, response and recovery phases of emergencies. Broad recommendations for ministries of health are to: (1) embed mental health and psychosocial support in national health and emergency preparedness plans; (2) put in place national guidelines, standards and supporting tools for the provision of mental health and psychosocial support during emergencies; (3) strengthen the capacity of health professionals to identify and manage priority mental disorders during emergencies; and (4) utilize opportunities generated by the emergency response to contribute to development of sustainable mental health-care services.

    Background The global burden of cardiovascular mortality is increasing, as is the number of large-scale humanitarian emergencies. The interaction between these phenomena is not well understood. This review aims to clarify the relationship between humanitarian emergencies and cardiovascular morbidity and mortality. Methods With assistance from a research librarian, electronic databases (PubMed, Scopus, CINAHL, Global Health) were searched in January 2014. Findings were supplemented by reviewing citations of included trials. Observational studies reporting the effect of natural disasters and conflict events on cardiovascular morbidity and mortality in adults since 1997 were included. Studies without a comparison group were not included. Double-data extraction was utilized to abstract information on acute coronary syndrome (ACS), acute decompensated heart failure (ADHF), and cardiac death (SCD). Review Manager 5.0 was used to create figures for qualitative synthesis (Version 5.2, Copenhagen Denmark, The Nordic Cochrane Centre). Results The search retrieved 1697 unique records; 24 studies were included (17 studies of natural disasters, 7 studies of conflict). These studies involved 14,583 cardiac events. All studies utilized retrospective designs: 4 were population-based, 15 were single-center, and 5 were multicenter studies. 23 studies utilized historical controls in the primary analysis, and 1 utilized primarily geographical controls. Conflicts are associated with an increase in long-term morbidity from ACS; the short-term effects of conflict vary by study. Natural disasters exhibit heterogeneous effects including increased occurrence of ACS, ADHF, and SCD. Conclusions In certain settings, humanitarian emergencies are associated with increased cardiac morbidity and mortality that may persist for years following the event. Humanitarian aid organizations should consider morbidity from non-communicable disease when planning relief and recuperation projects. PMID

  10. The impact of humanitarian emergencies on the prevalence of violence against children: an evidence-based ecological framework.

    PubMed

    2017-03-01

    Little is known about the patterns and mechanisms by which humanitarian emergencies may exacerbate violence against children. In this article, we propose using the ecological framework to examine the impact of humanitarian emergencies on interpersonal violence against children. We consider the literature that supports this framework and suggest future directions for research to fill identified gaps in the framework. The relationship between humanitarian emergencies and violence against children depends on risk factors at multiple levels, including a breakdown of child protection systems, displacement, threats to livelihoods, changing gender roles, changing household composition, overcrowded living conditions, early marriage, exposure to conflict or other emergency events, and alcohol abuse. The empirical evidence supporting the proposed emergency/violence framework is limited by cross-sectional study designs and a propensity to predominantly examine individual-level determinants of violence, especially exposure to conflict or emergency events. Thus, there is a pressing need to contextualize the relationship between conflict or emergency events and violence against children within the wider ecological and household dynamics that occur during humanitarian emergencies. Ultimately, this will require longitudinal observations of children, families and communities from before the emergency through recovery and improvements to ongoing global surveillance systems. More complete data will enable the humanitarian community to design effective, appropriate and well-targeted interventions.

    Burn scars still represent a challenge to the reconstructive surgeon. Their management requires a specific expertise and set up involving the possibility of long term rehabilitation and follow up. Cases encountered in humanitarian missions present additional issues. Often the local environment is not suitable for an appropriate treatment plan, requiring the case to be transferred to a foreign country for surgical care as part of an integrated international and multidisciplinary management. We present the case of a three year-old patient injured in a bomb explosion during the Arab Spring and suffering from severe scar contracture limiting thoracic and upper limb movement. After initial consultation at distance, transfer to our country was organized and an intensive surgical and rehabilitative program was carried out over three months. After five months, the patient returned to his home country where a supportive network had been set up for continued rehabilitation, ensuring follow up for over a year and ultimate success.

    This special issue of Third World Quarterly makes a case for redirecting attention and resources away from the 'war on terror' and focussing as a matter of urgency on the causes and consequences of global climate change. Global climate change must be recognised as an issue of national and international security. Increased competition for scarce resources and migration are key factors in the propagation of many of today's chronic complex humanitarian emergencies. The relentless growth of megacities in natural disaster hotspots places unprecedented numbers of vulnerable people at risk of disease and death. The Earth's fragile ecosystem has reached a critical tipping point. Today's most urgent need is for a collective endeavour on the part of the international community to redirect resources, enterprise and creativity away from the war on terror and to earnestly redeploy these in seeking solutions to the far greater and increasingly imminent threats that confront us as a consequence of global climate change.

    New applications of information and communication technology (ICT) are shaping the way we understand and provide humanitarian medical assistance in situations of disaster, disease outbreak or conflict. Each new crisis appears to be accompanied by advancements in humanitarian technology, leading to significant improvements in the humanitarian aid sector. However, ICTs raise ethical questions that warrant attention. Focusing on the context of humanitarian medical assistance, we review key domains of ICT innovation. We then discuss ethical challenges and uncertainties associated with the development and application of new ICTs in humanitarian medical assistance, including avoiding harm, ensuring privacy and security, responding to inequalities, demonstrating respect, protecting relationships, and addressing expectations. In doing so, we emphasize the centrality of ethics in humanitarian ICT design, application and evaluation.

    Introduction Understanding what enhances the motivation and performance of community health workers (CHWs) in humanitarian emergencies represents a key research gap within the field of human resources for health. This paper presents the research protocol for the Performance ImprovEment of CHWs in Emergency Settings (PIECES) research programme. Enhancing Learning and Research in Humanitarian Action (ELRHA) funded the development of this protocol as part of their Health in Humanitarian Crises (R2HC) call (No.19839). PIECES aims to understand what factors improve the performance of CHWs in level III humanitarian emergencies. Methods and analysis The suggested protocol uses a realist evaluation with multiple cases across the 3 country sites: Turkey, Iraq and Lebanon. Working with International Medical Corps (IMC), an initial programme theory was elicited through literature and document reviews, semistructured interviews and focus groups with IMC programme managers and CHWs. Based on this initial theory, this protocol proposes a combination of semistructured interviews, life histories and critical incident narratives, surveys and latent variable modelling of key constructs to explain how contextual factors work to trigger mechanisms for specific outcomes relating to IMC's 300+ CHWs' performance. Participants will also include programme staff, CHWs and programme beneficiaries. Realist approaches will be used to better understand ‘what works, for whom and under what conditions’ for improving CHW performance within humanitarian contexts. Ethics and dissemination Trinity College Dublin's Health Policy and Management/Centre for Global Health Research Ethics Committee gave ethical approval for the protocol development phase. For the full research project, additional ethical approval will be sought from: Université St. Joseph (Lebanon), the Ethics Committee of the Ministry of Health in Baghdad (Iraq) and the Middle East Technical University (Turkey).

    2004-06-01

    Changes in the nature of humanitarian crises and in the ways that the international community responds to such crises demand a radically overhauled role for the United Nations system. At a time when the UN and its member states are pursuing reform of some of that institution's most fundamental peace and security functions, this paper suggests that reform, too, is required to meet humanitarian crises of the future. This paper proposes a new type of operational role for the UN, while at the same time arguing that the UN has to place itself in the vanguard of humanitarian assistance as "the standard-bearer". The article draws many of its conclusions and recommendations from a recently completed study, requested by the Inter-Agency Standing Committee, concerning the effect for the UN system of changes in humanitarian financing.

    2011-04-01

    Complex biological systems operate under non-equilibrium conditions and exhibit emergent properties associated with correlated spatial and temporal structures. These properties may be individually unpredictable, but tend to be governed by power-law probability distributions and/or correlation. This article reviews the concepts that are invoked in the treatment of complex systems through a wide range of respiratory-related examples. Following a brief historical overview, some of the tools to characterize structural variabilities and temporal fluctuations associated with complex systems are introduced. By invoking the concept of percolation, the notion of multiscale behavior and related modeling issues are discussed. Spatial complexity is then examined in the airway and parenchymal structures with implications for gas exchange followed by a short glimpse of complexity at the cellular and subcellular network levels. Variability and complexity in the time domain are then reviewed in relation to temporal fluctuations in airway function. Next, an attempt is given to link spatial and temporal complexities through examples of airway opening and lung tissue viscoelasticity. Specific examples of possible and more direct clinical implications are also offered through examples of optimal future treatment of fibrosis, exacerbation risk prediction in asthma, and a novel method in mechanical ventilation. Finally, the potential role of the science of complexity in the future of physiology, biology, and medicine is discussed.

    Networks are mathematical structures that are universally used to describe a large variety of complex systems such as the brain or the Internet. Characterizing the geometrical properties of these networks has become increasingly relevant for routing problems, inference and data mining. In real growing networks, topological, structural and geometrical properties emerge spontaneously from their dynamical rules. Nevertheless we still miss a model in which networks develop an emergent complex geometry. Here we show that a single two parameter network model, the growing geometrical network, can generate complex network geometries with non-trivial distribution of curvatures, combining exponential growth and small-world properties with finite spectral dimensionality. In one limit, the non-equilibrium dynamical rules of these networks can generate scale-free networks with clustering and communities, in another limit planar random geometries with non-trivial modularity. Finally we find that these properties of the geometrical growing networks are present in a large set of real networks describing biological, social and technological systems. PMID:25985280

    This paper reviews advances in the development and use of two evidence-based assessment toolkits: the Seed System Security Assessment (SSSA) and the Emergency Market Mapping and Analysis (EMMA). Both were created in the past five years and have been employed in a range of acute and chronic stress contexts across Africa, Asia, and parts of the Americas, in periods of civil strife, displacement, and drought, as well as following earthquakes, flooding, and political instability. The aims of this paper are threefold: to review advances with regard to each tool; to compare how each toolkit gathers and uses evidence, while considering possibilities for greater complementarity; and to reflect on the nature of 'evidence' used to guide humanitarian response in sudden-onset and chronic crisis situations. A comparison highlights the importance of triangulation and informed analysis for drawing conclusions from imperfect evidence, understanding the limitations of each assessment methodology, and confronting tacit assumptions.

    Following large-scale disasters and major complex emergencies, especially in resource-poor settings, emergency surgery is practiced by Foreign Medical Teams (FMTs) sent by governmental and non-governmental organizations (NGOs). These surgical experiences have not yielded an appropriate standardized collection of data and reporting to meet standards required by national authorities, the World Health Organization, and the Inter-Agency Standing Committee's Global Health Cluster. Utilizing the 2011 International Data Collection guidelines for surgery initiated by Médecins Sans Frontières, the authors of this paper developed an individual patient-centric form and an International Standard Reporting Template for Surgical Care to record data for victims of a disaster as well as the co-existing burden of surgical disease within the affected community. The data includes surgical patient outcomes and perioperative mortality, along with referrals for rehabilitation, mental health and psychosocial care. The purpose of the standard data format is fourfold: (1) to ensure that all surgical providers, especially from indigenous first responder teams and others performing emergency surgery, from national and international (Foreign) medical teams, contribute relevant and purposeful reporting; (2) to provide universally acceptable forms that meet the minimal needs of both national authorities and the Health Cluster; (3) to increase transparency and accountability, contributing to improved humanitarian coordination; and (4) to facilitate a comprehensive review of services provided to those affected by the crisis.

    By November 2015, the West Africa Ebola epidemic had caused 28598 infections and 11299 deaths in the three countries most affected. The outbreak required rapid innovation and adaptation. Médecins sans Frontières (MSF) scaled up its usual 20-30 bed Ebola management centres (EMCs) to 100-300 beds with over 300 workers in some settings. This brought challenges in patient and clinical data management resulting from the difficulties of working safely with high numbers of Ebola patients. We describe a project MSF established with software developers and the Google Social Impact Team to develop context-adapted tools to address the challenges of recording Ebola clinical information. We share the outcomes and key lessons learned in innovating rapidly under pressure in difficult environmental conditions. Information on adoption, maintenance, and data quality was gathered through review of project documentation, discussions with field staff and key project stakeholders, and analysis of tablet data. In March 2015, a full prototype was deployed in Magburaka EMC, Sierra Leone. Inpatient data were captured on 204 clinical interactions with 34 patients from 5 March until 10 April 2015. Data continued to also be recorded on paper charts, creating theoretically identical record “pairs” on paper and tablet. 83 record pairs for 33 patients with 22 data items (temperature and symptoms) per pair were analysed. The overall Kappa coefficient for agreement between sources was 0.62, but reduced to 0.59 when rare bleeding symptoms were excluded, indicating moderate to good agreement. The time taken to deliver the product was more than that anticipated by MSF (7 months versus 6 weeks). Deployment of the tablet coincided with a dramatic drop in patient numbers and thus had little impact on patient care. We have identified lessons specific to humanitarian-technology collaborative projects and propose a framework for emergency humanitarian innovation. Time and effort is required to bridge

    The number of disasters, both natural as well as man-made, has been increasing in frequency in the recent years. This leads to short as well as long-term effects on food security and shelter, requiring humanitarian assistance. This article aims to identify the principles and standards that are applicable to food and shelter related aid that needs to be provided by the co-operation of the local government as well as the relevant supporting organizations. Also, food and shelter security during a disaster response is achieved through better preparedness. The level of preparedness must include risk assessment, contingency planning, stockpiling of equipment and supplies, emergency services and stand-by arrangements, communications, information management and coordination arrangements between various agencies involved. Discussing these issues would contribute to a better understanding of the implications of the right to adequate food and shelter, which in complex humanitarian emergencies, is one of the key necessities of the affected population.

    Many educators are looking for new ways to engage students and each other in order to enrich curriculum and the teaching-learning process. We describe an example of how we enacted teaching-learning approaches through the insights of complexity thinking, an approach that supports the emergence of new possibilities for teaching-learning in the classroom and online. Our story begins with an occasion to meet with 10 nursing colleagues in a three-hour workshop using four activities that engaged learning about complexity thinking and pedagogy. Guiding concepts for the collaborative workshop were nonlinearity, distributed decision-making, divergent thinking, self-organization, emergence, and creative exploration. The workshop approach considered critical questions to spark our collective inquiry. We asked, "What is emergent learning?" and "How do we, as educators and learners, engage a community so that new learning surfaces?" We integrated the arts, creative play, and perturbations within a complexity approach.

    Concern Worldwide and the University of Ulster Geophysics Research Group are engaged in a project to co-produce a suite of software and mapping tools to assess aftershock hazard in near real-time during the emergency response phase of earthquake disaster, and inform humanitarian emergency planning and response activities. This paper uses a social learning approach to evaluate this co-production process. Following Wenger (1999) we differentiate between the earthquake science and humanitarian communities of practice (CoP) along three dimensions: enterprise (the purpose of CoPs and the problems participants are working to address), repertoire (knowledge, skills, language), and identity (values and boundaries). We examine the effectiveness of learning between CoP, focusing on boundary work and objects, and various organisational structures and aspects of the wider political economy of learning that enable and hinder the co-production process. We conclude by identifying a number of ways to more effectively integrate earthquake science into humanitarian decision-making, policy development and programme design.

We review the World Health Organization's guidelines on pharmaceutical supply chain management and highlight their relevance for military humanitarian assistance missions. Given the important role of pharmaceuticals in addressing population health needs during humanitarian emergencies, a good understanding of how pharmaceuticals are supplied at the local level in different countries can help military health personnel identify the most appropriate supply options. Familiarity with international guidelines involved in cross-border movement of pharmaceuticals can improve the ability of military personnel to communicate more effectively with other actors involved in humanitarian and development spheres. Enhancing the knowledge base available to military personnel in terms of existing supply models and funding procedures can improve the effectiveness of humanitarian military operations and invite policy changes necessary to establish more flexible acquisition and funding regulations.

    Coordinated and effective interventions are critical for relief efforts to be successful in addressing the health needs of children in situations of armed conflict, population displacement, and/or food insecurity. We reviewed published literature and surveyed international relief organizations engaged in child health activities in complex emergencies. Our aim was to identify research needs and improve guidelines for the care of children. Much of the literature details the burden of disease and the causes of morbidity and mortality; few interventional studies have been published. Surveys of international relief organizations showed that most use World Health Organization (WHO), United Nations Children's Fund (UNICEF), and ministry of health guidelines designed for use in stable situations. Organizations were least likely to have formal guidelines on the management of asphyxia, prematurity, and infection in neonates; diagnosis and management of children with human immunodeficiency virus (HIV) infection; active case-finding and treatment of tuberculosis; paediatric trauma; and the diagnosis and management of mental-health problems in children. Guidelines often are not adapted to the different types of health-care workers who provide care in complex emergencies. Evidence-based, locally adapted guidelines for the care of children in complex emergencies should be adopted by ministries of health, supported by WHO and UNICEF, and disseminated to international relief organizations to ensure appropriate, effective, and uniform care.

    2001-04-01

    Many studies have shown a positive association between both migration and temporary expatriation and HIV risk. This association is likely to be similar or even more pronounced for forced migrants. In general, HIV transmission in host-migrant or host-forced-migrant interactions depends on the maturity of the HIV epidemic in both the host and the migrant population, the relative seroprevalence of HIV in the host and the migrant population, the prevalence of other sexually transmitted infections (STIs) that may facilitate transmission, and the level of sexual interaction between the two communities. Complex emergencies are the major cause of mass population movement today. In complex emergencies, additional factors such as sexual interaction between forced-migrant populations and the military; sexual violence; increasing commercial sex work; psychological trauma; and disruption of preventive and curative health services may increase the risk for HIV transmission. Despite recent success in preventing HIV infection in stable populations in selected developing countries, internally displaced persons and refugees (or forced migrants) have not been systematically included in HIV surveillance systems, nor consequently in prevention activities. Standard surveillance systems that rely on functioning health services may not provide useful data in many complex emergency settings. Secondary sources can provide some information in these settings. Little attempt has been made, however, to develop innovative HIV surveillance systems in countries affected by complex emergencies. Consequently, data on the HIV epidemic in these countries are scarce and HIV prevention programs are either not implemented or interventions are not effectively targeted. Second generation surveillance methods such as cross-sectional, population-based surveys can provide rapid information on HIV, STIs, and sexual behavior. The risks for stigmatization and breaches of confidentiality must be recognized

    BACKGROUND: In response to the Kosovo crisis, Canada received 5,500 Albanian Kosovar refugees in 1999 as part of the emergency humanitarian evacuation and settlement effort. This study attempts to describe the experiences of service providers at the international, national, and local levels, involved in the organization and delivery of health and settlement services in Canada for the Kosovar refugees. METHODS: A qualitative case study design using key informant interviews was used. Nominated sampling was used to identify 17 individuals involved in the organization and delivery of health and settlement. Key themes were identified and recommendations made to provide a framework for the development of policy to guide response to future humanitarian emergencies. RESULTS: Six themes emerged: (1) A sense of being overwhelmed, (2) A multitude of health issues, (3) critical challenges in providing health care, (4) access to health and settlement services, (5) overall successes and (6) need for a coordinated approach to migration health. CONCLUSIONS: For those involved, the experience was overwhelming but rewarding. Interviewees' major concerns were the need for a more comprehensive and coordinated approach to the flow of medical information and handling of specific health problems.

  11. Pattern Formation and Complexity Emergence

    NASA Astrophysics Data System (ADS)

    Berezin, Alexander A.

    2001-03-01

    Success of nonlinear modelling of pattern formation and self-organization encourages speculations on informational and number theoretical foundations of complexity emergence. Pythagorean "unreasonable effectiveness of integers" in natural processes is perhaps extrapolatable even to universal emergence "out-of-nothing" (Leibniz, Wheeler). Because rational numbers (R = M/N) are everywhere dense on real axis, any digital string (hence any "book" from "Library of Babel" of J.L.Borges) is "recorded" infinitely many times in arbitrary many rationals. Furthermore, within any arbitrary small interval there are infinitely many Rs for which (either or both) integers (Ms and Ns) "carry" any given string of any given length. Because any iterational process (such as generation of fractal features of Mandelbrot Set) is arbitrary closely approximatable with rational numbers, the infinite pattern of integers expresses itself in generation of complexity of the world, as well as in emergence of the world itself. This "tunnelling" from Platonic World ("Platonia" of J.Barbour) to a real (physical) world is modern recast of Leibniz's motto ("for deriving all from nothing there suffices a single principle").

    Background: Surgical capacity assessments in low-income countries have demonstrated critical deficiencies. Though vital for planning capacity improvements, these assessments are resource intensive and impractical during the planning phase of a humanitarian crisis. This study aimed to determine cesarean sections to total operations performed (CSR) and emergency herniorrhaphies to all herniorrhaphies performed (EHR) ratios from Médecins Sans Frontières Operations Centre Brussels (MSF-OCB) projects and examine if these established metrics are useful proxies for surgical capacity in low-income countries affected by crisis. Methods: All procedures performed in MSF-OCB operating theatres from July 2008 through June 2014 were reviewed. Projects providing only specialty care, not fully operational or not offering elective surgeries were excluded. Annual CSRs and EHRs were calculated for each project. Their relationship was assessed with linear regression. Results: After applying the exclusion criteria, there were 47,472 cases performed at 13 sites in 8 countries. There were 13,939 CS performed (29% of total cases). Of the 4,632 herniorrhaphies performed (10% of total cases), 30% were emergency procedures. CSRs ranged from 0.06 to 0.65 and EHRs ranged from 0.03 to 1.0. Linear regression of annual ratios at each project did not demonstrate statistical evidence for the CSR to predict EHR [F(2,30)=2.34, p=0.11, R2=0.11]. The regression equation was: EHR = 0.25 + 0.52(CSR) + 0.10(reason for MSF-OCB assistance). Conclusion: Surgical humanitarian assistance projects operate in areas with critical surgical capacity deficiencies that are further disrupted by crisis. Rapid, accurate assessments of surgical capacity are necessary to plan cost- and clinically-effective humanitarian responses to baseline and acute unmet surgical needs in LICs affected by crisis. Though CSR and EHR may meet these criteria in ‘steady-state’ healthcare systems, they may not be useful during

    The accurate interpretation of mortality surveys in humanitarian crises is useful for both public health responses and security responses. Recent examples suggest that few medical personnel and researchers can accurately interpret the validity of a mortality survey in these settings. Using an example of a mortality survey from the Democratic Republic of Congo (DRC), we demonstrate important methodological considerations that readers should keep in mind when reading a mortality survey to determine the validity of the study and the applicability of the findings to their settings.

  15. Earth Science Data and Models for Improved Targeting of Humanitarian Aid

    2011-01-01

    Humanitarian assistance to developing countries has long focused on countries that have political, economic and strategic interest to the United States. Recent changes in global security concerns have heightened the perception that humanitarian action is becoming increasingly politicized. This is seen to be largely driven by the 'global war on terror' along with a push by donors and the United Nations for closer integration between humanitarian action and diplomatic, military and other spheres of engagement in conflict and crisis-affected states (HPG 2010). As we enter an era of rising commodity prices and increasing uncertainty in global food production due to a changing climate, scientific data and analysis will be increasingly important to improve the targeting of humanitarian assistance. Earth science data enables appropriate humanitarian response to complex food emergencies that arise in regions outside the areas of current strategic and security focus. As the climate changes, new places will become vulnerable to food insecurity and will need emergency assistance. Earth science data and multidisciplinary models will enable an information-based comparison of need that goes beyond strategic and political considerations to identify new hotspots of food insecurity as they emerge. These analyses will improve aid targeting and timeliness while reducing strategic risk by highlighting new regions at risk of crisis in a rapidly changing world. Improved targeting with respect to timing and location could reduce cost while increasing the likelihood that those who need aid get it.

    2009-07-01

    This paper seeks to contribute to an improved information management and exchange between humanitarian organisations and military agents in complex emergencies. To do so, a theoretical information management process model was developed and applied to the case of information management between International Security Assistance Force troops and humanitarian organisations such as Cordaid, DACAAR and the International Office for Migration in Kabul, Afghanistan. Based on this analysis the main shortcomings and problems in each stage of the information management process were identified. These include a lack of structured information databases, the absence of identification of information needs, and an over-classification of documents by the military. Using a logical framework analysis, six major improvement tactics were developed, including the creation of more overlap in rotations of personnel, the specification of aims and tasks regarding information management, the improvement of skills and competences of personnel involved, and the introduction of regular joint civil-military evaluations.

    2014-01-01

    Humanitarian catastrophes,” conflicts and calamities generating both widespread human suffering and destructive events, require a wide range of emergency resources. This paper answers a number of questions that humanitarian catastrophes generate: Why and how do the most-developed countries—those with the resources, capabilities, and willingness to help—intervene in specific types of disasters? What ethical and legal guidelines shape our interventions? How well do we achieve our goals? It then suggests a number of changes to improve humanitarian responses, including better NGO-government cooperation, increased research on the best disaster response methods, clarification of the criteria and roles for humanitarian (military) interventions, and development of post-2015 Millennium Development Goals with more accurate progress measures.

    Recent years have seen significant growth in both the size and profile of the humanitarian sector. However, little research has focused upon the constructions of humanitarian practice negotiated by agencies and their workers that serve to sustain engagement in the face personal challenges and critique of the humanitarian enterprise. This study used the public narrative of 129 website postings by humanitarian workers deployed with the health-focused international humanitarian organization Médecins Sans Frontières (MSF) to identify recurrent themes in personal, organizationally-condoned, public discourse regarding humanitarian practice. Data represented all eligible postings from a feature on the agency's UK website from May 2002 to April 2012. The text of postings was analysed with respect to emergent themes on an iterative basis. Comprehensive coding of material was achieved through a thematic structure that reflected the core domains of project details, the working environment, characteristics of beneficiaries and recurrent motivational sub-texts. Features of the co-construction of narratives include language serving to neutralize complex political contexts; the specification of barriers as substantive but surmountable; the dominance of the construct of national-international in understanding the operation of teams; intense personal identification with organization values; and the use of resilience as a framing of beneficiary adaptation and perseverance in conditions that--from an external perspective--warrant despair and withdrawal. Recurrent motivational sub-texts include 'making a difference' and contrasts with 'past professional constraints' and 'ordinary life back home.' The prominence of these sub-texts not only highlights key personal agendas but also suggests--notwithstanding policy initiatives regarding stronger contextual rooting and professionalism--continuing organizational emphasis on externality and volunteerism. Overall, postings illustrate a

    2016-04-01

    The challenges of achieving successful inter-agency logistic coordination in preparing for and responding to natural disasters and complex emergencies are both well understood and well documented. However, although many of these challenges remain unresolved, the literature reveals that the organisations that form the urban search and rescue (USAR) community have attained a high level of coherence and interoperability that results in a highly efficient and effective response. Therefore, this paper uses the idea of 'borrowing' from other fields as it explores how the processes and procedures used by the USAR community might be applied to improve humanitarian logistic operations. The paper analyses the USAR model and explores how the resultant challenges might be addressed in a humanitarian logistic context. The paper recommends that further research be undertaken in order to develop a modified USAR model that could be operationalised by the international community of humanitarian logisticians.

    2009-01-01

    The ornate and diverse patterns of seashells testify to the complexity of living systems. Provocative computational explorations have shown that similarly complex patterns may arise from the collective interaction of a small number of rules. This suggests that, although a system may appear complex, it may still be understood in terms of simple principles. It is still debatable whether shell patterns emerge from some undiscovered simple principles, or are the consequence of an irreducibly complex interaction of many effects. Recent work by Boettiger, Ermentrout and Oster on the biological mechanisms of shell patterning has provided compelling evidence that, at least for this system, simplicity produces diversity and complexity.

  2. Virtues and humanitarian ethics.

    PubMed

    Löfquist, Lars

    2017-01-01

    This paper analyses the contribution of virtue ethics, the study of good character traits, to the humanitarian context. It argues that a virtue ethics perspective paints a realistic picture of the use of ethical standards in morally complex circumstances. Virtuous relief workers can employ standards in their thinking, but they are also committed to professional excellence that goes beyond any formal code. The concept of virtue ethics places a stress on moral development, which can be facilitated by role models that impart modest and feasible ideals. However, virtue ethics cannot provide simple guidelines on how to resolve difficult situations. It is possible that two virtuous persons can disagree on what should be done in a particular instance. In addition, a virtue ethics perspective emphasises the need for both individuals and organisations to discuss the actual purpose of relief work in order to pinpoint the virtues of a good relief professional.

    Corruption is a threat to the purpose of humanitarian assistance. Until fairly recently, humanitarian assistance has not been considered an important arena in broader efforts aimed at curbing corruption, and corruption has not always been considered a particularly important concern for humanitarian assistance despite the obviously challenging nature of the context of humanitarian emergencies. Corruption, though, is a threat to humanitarian action because it can prevent assistance from getting to the people who most need it, and because it can potentially undermine public support for such assistance. This paper examines perceptions of corruption and its affects, documents best practices, and outlines gaps in understanding. It suggests recommendations for improving the capacity of humanitarian agencies to prevent and manage the risk of corruption. Agencies have taken steps to combat corruption and improve accountability--downwards and upwards--but scope remains for improvement and for greater sharing of learning and good practice.

    2010-04-01

    This paper explores the meta functions of humanitarianism--that is, the functions that, as an ideology, a movement and a profession, it performs, wittingly or unwittingly, in the early twenty-first century. The term humanitarianism is used as shorthand to encompass a complex set of currents of thought, actions and institutions of which the boundaries are unclear. The focus is on mainstream humanitarianism, the dominant Northern/Western enterprise. The paper first discusses the relationship between humanitarianism and globalised power. It goes on to examine three types of functions that humanitarianism and humanitarian action perform: 'macro' functions--the deep undercurrents, power relations and values that humanitarianism articulates and transmits; 'meso' functions--those that relate to the political economy of humanitarian action and to the mechanics (rather than to the ideology) of globalisation; and 'micro' functions that relate to the motivations of the individuals who devote their energies to humanitarianism.

    2008-01-01

    Each year, millions of people worldwide are affected by disasters, underscoring the importance of effective relief efforts. Many highly visible disaster responses have been inefficient and ineffective. Humanitarian agencies typically play a key role in disaster response (eg, procuring and distributing relief items to an affected population, assisting with evacuation, providing healthcare, assisting in the development of long-term shelter), and thus their efficiency is critical for a successful disaster response. The field of disaster and emergency response modeling is well established, but the application of such techniques to humanitarian logistics is relatively recent. This article surveys models of humanitarian response logistics and identifies promising opportunities for future work. Existing models analyze a variety of preparation and response decisions (eg, warehouse location and the distribution of relief supplies), consider both natural and manmade disasters, and typically seek to minimize cost or unmet demand. Opportunities to enhance the logistics of humanitarian response include the adaptation of models developed for general disaster response; the use of existing models, techniques, and insights from the literature on commercial supply chain management; the development of working partnerships between humanitarian aid organizations and private companies with expertise in logistics; and the consideration of behavioral factors relevant to a response. Implementable, realistic models that support the logistics of humanitarian relief can improve the preparation for and the response to disasters, which in turn can save lives.

    Non-military government agencies and non-governmental organizations (NGOs) have made great strides in the evaluation of humanitarian medical work, and have learned valuable lessons regarding monitoring and evaluation (M&E) that may be equally as valuable to military medical personnel. We reviewed the recent literature by the worldwide humanitarian community regarding the art and science of M&E, with focus toward military applications. The successes and failures of past humanitarian efforts have resulted in prolific analyses. Alliances of NGOs set the standard for humanitarian quality and M&E standards. Military medical personnel can apply some of these standards to military humanitarian M&E in complex and stability operations. The authors believe that the NGO community?s M&E standards should be applied to improve evaluation of U.S. military medical humanitarian operations.

    Treatment of non-communicable diseases such as cancer in refugees is neglected in low-income and middle-income countries, but is of increasing importance because the number of refugees is growing. The UNHCR, through exceptional care committees (ECCs), has developed standard operating procedures to address expensive medical treatment for refugees in host countries, to decide on eligibility and amount of payment. We present data from funding applications for cancer treatments for refugees in Jordan between 2010 and 2012, and in Syria between 2009 and 2011. Cancer in refugees causes a substantial burden on the health systems of the host countries. Recommendations to improve prevention and treatment include improvement of health systems through standard operating procedures and innovative financing schemes, balance of primary and emergency care with expensive referral care, development of electronic cancer registries, and securement of sustainable funding sources. Analysis of cancer care in low-income refugee settings, particularly in sub-Saharan Africa, is needed to inform future responses.

    The humanitarian crisis which followed in the wake of the genocidal regime in Rwanda in 1994 generated massive media attention and an unprecedented outpouring of international public and private assistance. In late 1997, the Rwanda refugee population in Zaire was subjected to a disaster of similarly epic proportions as a result of military action. Yet this crisis went relatively under-reported and failed to attract substantial aid funds, particularly from official donors. This paper seeks to document and account for the demise of the humanitarian imperative. It confronts a number of the criticisms of humanitarian action, concluding that, rather than being flawed, traditional humanitarian values remain valid and should be defended wherever there are situations of conflict.

    Cities are fast becoming new territories of violence. The humanitarian consequences of many criminally violent urban settings are comparable to those of more traditional wars, yet despite the intensity of the needs, humanitarian aid to such settings is limited. The way in which humanitarian needs are typically defined, fails to address the problems of these contexts, the suffering they produce and the populations affected. Distinctions between formal armed conflicts, regulated by international humanitarian law, and other violent settings, as well as those between emergency and developmental assistance, can lead to the neglect of populations in distress. It can take a lot of time and effort to access vulnerable communities and implement programmes in urban settings, but experience shows that it is possible to provide humanitarian assistance with a significant focus on the direct and indirect health consequences of violence outside a traditional conflict setting. This paper considers the situation of Port-au-Prince (Haiti), Rio de Janeiro (Brazil) and Guatemala City (Guatemala).

    Introduction: Syrian refugees displaced into Turkey have attempted high-risk sea migrations to reach safer destinations in Europe, most often initially arriving on the Greek island of Lesvos. These refugees were often in need of basic humanitarian assistance that has been provided in part by a new category of ad hoc grassroots organizations (AHGOs). The aim of this study was to understand the internal and external operations of these AHGOs and their role on Lesvos. Methods: The experiences of AHGOs were investigated through a qualitative research design utilizing semi-structured interviews with organization leaders and spokespersons. AHGOs identified through media and social media sources as new Lesvos-specific organizations were purposively invited to complete an interview over phone, Skype or email. Data analysis of the transcribed interviews was performed by Systematic Text Condensation. Results: Forty-one organizations were contacted and 13 interviews were conducted. Most organizations were formed in autumn 2015 responding to the greater influx of refugees and migrants at that time and reported an absence of professional humanitarian agencies providing aid on Lesvos. Three categories emerged from the material. Features of organizations; Features of volunteers and; Evolution of AHGOs. The organizations perceived themselves capable of evaluating needs, mobilizing resources, funding and providing quick response. The volunteers came with limited humanitarian experience and from a wide variety of nationalities and professional backgrounds, and the organizations developed while on Lesvos. Discussion: Knowledge from our findings of AHGOs response to this complex disaster on Lesvos could be utilized in future catastrophes. We conclude that AHGOs may prove effective at providing humanitarian aid in a surge response when international non-governmental organizations are unable to respond quickly. In future complex disasters AHGOs should be recognized as new humanitarian

    Conflict almost completely destroyed Rwanda's infrastructure in 1994. Natural disasters, as well as disasters caused by humans, have severely challenged humanitarian aid available within the country. In this study, we have analysed the experiences of nongovernmental organizations since the summer of 1994 to evaluate how these difficulties may be overcome. One of the problems identified has been restrictions on the ability to introduce effective health planning due to the poor quality of available local information. The implementation of effective plans that show due consideration to the environment and society is clearly necessary. Effective monitoring and detailed observation are identified as being essential to the continuity of existing humanitarian assistance. PMID:10444885

    The creation of new technologies that serve humanity holds the potential to help end global poverty. Unfortunately, relatively little is done in engineering education to support engineers' humanitarian efforts. Here, various strategies are introduced to augment the teaching of engineering ethics with the goal of encouraging engineers to serve as effective volunteers for community service. First, codes of ethics, moral frameworks, and comparative analysis of professional service standards lay the foundation for expectations for voluntary service in the engineering profession. Second, standard coverage of global issues in engineering ethics educates humanitarian engineers about aspects of the community that influence technical design constraints encountered in practice. Sample assignments on volunteerism are provided, including a prototypical design problem that integrates community constraints into a technical design problem in a novel way. Third, it is shown how extracurricular engineering organizations can provide a theory-practice approach to education in volunteerism. Sample completed projects are described for both undergraduates and graduate students. The student organization approach is contrasted with the service-learning approach. Finally, long-term goals for establishing better infrastructure are identified for educating the humanitarian engineer in the university, and supporting life-long activities of humanitarian engineers.

    Opposing positions on mental disorder in current psychiatry, their origins and therapy are presented through a few extreme viewpoints. Considering the foundations of the 'medical model' of psychiatric disorder (Griesinger), it is evident that this model is not a closed system, but rather an open approach which still has validity today. The humanitarian roots of psychiatry prevented Griesinger from treating various positions in an absolute or ideological manner. Finally, the concept of 'illness' is discussed in relation to psychophysiological activation research. Pathology changes in each different situation and is therefore not a static phenomenon. Mental disturbance is not determined by absolute measures, but rather by a reduction in variability of reactions to the particular situation. This concept of illness can determine somato-, psycho-, and sociotherapeutic measures. Psychiatry can only remain based on humanitarian concepts as long as the sciences upon which it is founded are kept in appropriate relation to one another.

Recommendations for improving the effectiveness of DoD HA under Overseas Humanitarian Disaster and Civic Aid programs include: ensuring adequate staffing to meet the complex, dynamic nature of humanitarian missions and measuring the effectiveness of each project in mandatory, standardized AARs. For medical HA projects, application of public health strategies would compliment the patient care approach of the majority of medical projects to date. This offers possibilities for enhancing host nation infrastructure, allowing improvements beyond the short period of most military humanitarian projects.

    Some real-world networks are shown to be fractal or self-similar. It is widespread that such a phenomenon originates from the repulsion between hubs or disassortativity. Here we show that this common belief fails to capture the causality. Our key insight to address it is to pinpoint links critical to fractality. Those links with small edge betweenness centrality (BC) constitute a special architecture called fractal reference system, which gives birth to the fractal structure of those reported networks. In contrast, a small amount of links with high BC enable small-world effects, hiding the intrinsic fractality. With enough of such links removed, fractal scaling spontaneously arises from nonfractal networks. Our results provide a multiple-scale view on the structure and dynamics and place fractality as a generic organizing principle of complex networks on a firmer ground.

Development of this research agenda was initiated at the Humanitarian Health Ethics Forum (HHE Forum) convened in Hamilton, Canada in November 2012. The HHE Forum identified priority avenues for advancing policy and practice for ethics in humanitarian health action. The main topic areas examined were: experiences and perceptions of humanitarian health ethics; training and professional development initiatives for humanitarian health ethics; ethics support for humanitarian health workers; impact of policies and project structures on humanitarian health ethics; and theoretical frameworks and ethics lenses. Key research questions for each topic area are presented, as well as proposed strategies for advancing this research agenda. Pursuing the research agenda will help strengthen the ethical foundations of humanitarian health action. PMID:25687273

    Real complex systems are not rigidly structured; no clear rules or blueprints exist for their construction. Yet, amidst their apparent randomness, complex structural properties universally emerge. We propose that an important class of complex systems can be modeled as an organization of many embedded levels (potentially infinite in number), all of them following the same universal growth principle known as preferential attachment. We give examples of such hierarchy in real systems, for instance, in the pyramid of production entities of the film industry. More importantly, we show how real complex networks can be interpreted as a projection of our model, from which their scale independence, their clustering, their hierarchy, their fractality, and their navigability naturally emerge. Our results suggest that complex networks, viewed as growing systems, can be quite simple, and that the apparent complexity of their structure is largely a reflection of their unobserved hierarchical nature.

    PubMed

    2006-12-01

    The tendency today to privatise many activities hitherto considered the exclusive preserve of the state has given rise to sharp debate. The specific nature of humanitarian emergencies elucidates in particularly stark contrast some of the main challenges connected to the privatisation and outsourcing of essential public services, such as the provision of drinking water and health care. Privatising the realms of defence and security, which are at the very core of state prerogative, raises several legal and humanitarian concerns. This article focuses on the roles and responsibilities of the various parties involved in armed conflicts, especially those of private companies engaged in security, intelligence and interrogation work, and in the provision of water supply and health services. It highlights the need for humanitarian and development actors to grasp better the potential risks and opportunities related to privatisation and outsourcing with a view to supplying effective protection and assistance to communities affected by war.

    PubMed

    Connolly, Máire A; Gayer, Michelle; Ryan, Michael J; Salama, Peter; Spiegel, Paul; Heymann, David L

    Communicable diseases, alone or in combination with malnutrition, account for most deaths in complex emergencies. Factors promoting disease transmission interact synergistically leading to high incidence rates of diarrhoea, respiratory infection, malaria, and measles. This excess morbidity and mortality is avoidable as effective interventions are available. Adequate shelter, water, food, and sanitation linked to effective case management, immunisation, health education, and disease surveillance are crucial. However, delivery mechanisms are often compromised by loss of health staff, damage to infrastructure, insecurity, and poor co-ordination. Although progress has been made in the control of specific communicable diseases in camp settings, complex emergencies affecting large geographical areas or entire countries pose a greater challenge. Available interventions need to be implemented more systematically in complex emergencies with higher levels of coordination between governments, UN agencies, and non-governmental organisations. In addition, further research is needed to adapt and simplify interventions, and to explore novel diagnostics, vaccines, and therapies.

    Women and children are vulnerable to sexual violence in times of conflict, and the risk persists even after they have escaped the conflict area. The impact of rape goes far beyond the immediate effects of the physical attack and has long-lasting consequences. We describe the humanitarian community's response to sexual violence and rape in times of war and civil unrest by drawing on the experiences of Médecins Sans Frontières/Doctors Without Borders and other humanitarian agencies. Health care workers must have a keen awareness of the problem and be prepared to respond appropriately. This requires a comprehensive intervention protocol, including antibiotic prophylaxis, emergency contraception, referral for psychological support, and proper documentation and reporting procedures. Preventing widespread sexual violence requires increasing the security in refugee camps. It also requires speaking out and holding states accountable when violations of international law occur. The challenge is to remain alert to these often hidden, but extremely destructive, crimes in the midst of a chaotic emergency relief setting.

    2010-02-01

    There is growing acknowledgment that research in the postconflict field needs to include a focus on social conditions. The authors applied structural equation modeling to epidemiologic data obtained from postconflict Timor-Leste, to examine for links involving potentially traumatic events and sociodemographic factors (age, gender, educational levels, and unemployment) with psychological symptoms and functioning. Exposure to trauma and lack of education emerged as most relevant with psychological distress impacting on education in the urban area. Age and gender exerted influences at different points in the model consistent with the known history of Timor. Although based on cross-sectional data, the model supports the relevance of past trauma, posttraumatic distress, and postconflict social conditions to functioning in societies such as Timor-Leste.

  13. The humanitarian common logistic operating picture: a solution to the inter-agency coordination challenge.

    2017-01-01

    Although significant progress has been made in developing the practice of humanitarian logistics, further improvements in efficiency and effectiveness have the potential to save lives and reduce suffering. This paper explores how the military/emergency services' concept of a common operating picture (COP) can be adapted to the humanitarian logistics context, and analyses a practical and proven approach to addressing the key challenge of inter-agency coordination and decision-making. Successful adaptation could provide the mechanism through which predicted and actual demands, together with the location and status of material in transit, are captured, evaluated, and presented in real time as the basis for enhanced decision-making between actors in the humanitarian supply network. Through the introduction of a humanitarian logistics COP and its linkages to national disaster management systems, local communities and countries affected by disasters and emergencies will be better placed to oversee and manage their response activities.

  14. 'The Ethiopian famine' revisited: band aid and the antipolitics of celebrity humanitarian action.

    PubMed

    Müller, Tanja R

    2013-01-01

    In many ways the Ethiopian famine of 1983-85 has served as a watershed with respect to humanitarian action. One of its lasting legacies has been the emergence of Band Aid and the subsequent increase in celebrity humanitarianism. A revisiting of the events of 1983-85 occurred in 2010 during a dispute in which it was alleged that a portion of the donations of Band Aid were spent on arms purchases. This paper takes this controversy as its starting point. It goes on to use the theoretical reflections of Giorgio Agamben to consider the dynamics that unfolded during the Ethiopian famine of 1983-85 and to analyse the underlying conceptualisation behind the emergence of Band Aid-type celebrity humanitarianism. The paper concludes with some wider thoughts on how the in essence antipolitical agenda of celebrity humanitarian action is transported into the everyday understanding of 'African disaster', resulting ultimately in the perpetuation of hegemonic control by the global North.

  15. Malaria control in complex emergencies: the example of East Timor.

    PubMed

    Kolaczinski, Jan; Webster, Jayne

    2003-01-01

    Malaria control in complex emergencies forms part of the World Health Organization's Roll Back Malaria (RBM) initiative. The underlying principle is a partnership with other UN agencies and non-governmental organizations, with the RBM programme providing support to its implementing partners through a Technical Support Network. This innovative approach was applied for the first time in 1999-2000, following the return of stability and security to East Timor. The RBM programme assessed the malaria situation during the acute emergency phase and identified programme priorities. Two non-governmental organizations were subsequently invited to operate as implementing partners. Individual proposals were developed and funding obtained, but no overall organizational and planning framework was established. Implementation commenced quickly, addressing aspects of prevention, diagnosis and treatment. As East Timor progressed into the transitional phase towards independence, the programme was not realigned to the changing context. Absence of monitoring and evaluation was a significant factor contributing to the resulting continuation of emergency malaria control activities well into the transitional phase. East Timor's example of malaria control in complex emergencies provides important lessons: (i). partnership roles and responsibilities should be clearly defined from the beginning of the programme, (ii). planning, monitoring and evaluation should be instigated from the start with the aim to develop long-term strategies and policies, (iii). expert support is necessary to guide implementation at all stages, (iv). the flexibility to react to changing priorities should be ensured as the context of the emergency and the available health structure changes, and (v). the implementation process, and alternatives for continuation of activities once the RBM complex emergency partnership has terminated, should be clarified to all partners involved.

    Quantifying the capacity of a given node or a bunch of nodes in maintaining a system's controllability is a crucial problem in complex networks and control theory. We give a systematic analysis of the ability of a single node or a pairs of nodes to control an undirected unweighted chain and ring. By combining algebraic theory and graph spectrum analysis, we derive analytic expressions for the control range of some given control inputs and find that complex phenomena emerge even from these simplest graph structures. Specifically, the control range is sensitive to the location of driver nodes and shows complex periodic behaviors. Our findings have implications for evaluating the control range and practically controlling complex networks.

    Experimental econophysics is concerned with statistical physics of humans in the laboratory, and it is based on controlled human experiments developed by physicists to study some problems related to economics or finance. It relies on controlled human experiments in the laboratory together with agent-based modeling (for computer simulations and/or analytical theory), with an attempt to reveal the general cause-effect relationship between specific conditions and emergent properties of real economic/financial markets (a kind of complex adaptive systems). Here I review the latest progress in the field, namely, stylized facts, herd behavior, contrarian behavior, spontaneous cooperation, partial information, and risk management. Also, I highlight the connections between such progress and other topics of traditional statistical physics. The main theme of the review is to show diverse emergent properties of the laboratory markets, originating from self-organization due to the nonlinear interactions among heterogeneous humans or agents (complexity).

    The zebrafish (Danio rerio) is rapidly becoming a popular model organism in pharmacogenetics and neuropharmacology. Both larval and adult zebrafish are currently used to increase our understanding of brain function, dysfunction, and their genetic and pharmacological modulation. Here we review the developing utility of zebrafish in the analysis of complex brain disorders (including, for example, depression, autism, psychoses, drug abuse and cognitive disorders), also covering zebrafish applications towards the goal of modeling major human neuropsychiatric and drug-induced syndromes. We argue that zebrafish models of complex brain disorders and drug-induced conditions have become a rapidly emerging critical field in translational neuropharmacology research. PMID:24412421

    Vargas, David L.

    Emerging quantum simulator technologies provide a new challenge to quantum many body theory. Quantifying the emergent order in and predicting the dynamics of such complex quantum systems requires a new approach. We develop such an approach based on complex network analysis of quantum mutual information. First, we establish the usefulness of quantum mutual information complex networks by reproducing the phase diagrams of transverse Ising and Bose-Hubbard models. By quantifying the complexity of quantum cellular automata we then demonstrate the applicability of complex network theory to non-equilibrium quantum dynamics. We conclude with a study of student collaboration networks, correlating a student's role in a collaboration network with their grades. This work thus initiates a quantitative theory of quantum complexity and provides a new tool for physics education research. (Abstract shortened by ProQuest.).

  20. Emergent complexity of the cytoskeleton: from single filaments to tissue

    Despite their overwhelming complexity, living cells display a high degree of internal mechanical and functional organization which can largely be attributed to the intracellular biopolymer scaffold, the cytoskeleton. Being a very complex system far from thermodynamic equilibrium, the cytoskeleton's ability to organize is at the same time challenging and fascinating. The extensive amounts of frequently interacting cellular building blocks and their inherent multifunctionality permits highly adaptive behavior and obstructs a purely reductionist approach. Nevertheless (and despite the field's relative novelty), the physics approach has already proved to be extremely successful in revealing very fundamental concepts of cytoskeleton organization and behavior. This review aims at introducing the physics of the cytoskeleton ranging from single biopolymer filaments to multicellular organisms. Throughout this wide range of phenomena, the focus is set on the intertwined nature of the different physical scales (levels of complexity) that give rise to numerous emergent properties by means of self-organization or self-assembly.

  1. Understanding complexity in neurodegenerative diseases: in silico reconstruction of emergence

    Healthy functioning is an emergent property of the network of interacting biomolecules that comprise an organism. It follows that disease (a network shift that causes malfunction) is also an emergent property, emerging from a perturbation of the network. On the one hand, the biomolecular network of every individual is unique and this is evident when similar disease-producing agents cause different individual pathologies. Consequently, a personalized model and approach for every patient may be required for therapies to become effective across mankind. On the other hand, diverse combinations of internal and external perturbation factors may cause a similar shift in network functioning. We offer this as an explanation for the multi-factorial nature of most diseases: they are “systems biology diseases,” or “network diseases.” Here we use neurodegenerative diseases, like Parkinson's disease (PD), as an example to show that due to the inherent complexity of these networks, it is difficult to understand multi-factorial diseases with simply our “naked brain.” When describing interactions between biomolecules through mathematical equations and integrating those equations into a mathematical model, we try to reconstruct the emergent properties of the system in silico. The reconstruction of emergence from interactions between huge numbers of macromolecules is one of the aims of systems biology. Systems biology approaches enable us to break through the limitation of the human brain to perceive the extraordinarily large number of interactions, but this also means that we delegate the understanding of reality to the computer. We no longer recognize all those essences in the system's design crucial for important physiological behavior (the so-called “design principles” of the system). In this paper we review evidence that by using more abstract approaches and by experimenting in silico, one may still be able to discover and understand the design principles that

    Human beings develop the land and transform land use patterns, constructing artificial structures. Among them, the city is a representative system and its morphology has attracted much attention. While most existing studies have been devoted to individual dynamics and focused on the proximity of specific areas of a city, we here pay attention to the city as a complex system, where interactions between individuals give rise to emergent properties. Specifically, analyzing the big data on every building in Seoul City, we specify the relevant interactions among constituents and probe the emergence of complex land use patterns. In particular, based on the empirical observations, we illustrate that interactions between land uses are frustrated, which serves as a basic postulate of the theory of urban morphology. We examine this conjecture with the help of a layered Ising-type model and disclose that the actual land use pattern emerges at the criticality of the system in the presence of heterogeneously distributed fields. It is also remarked that our model, allowing quantitative predictions, can easily be applied to other cities around the world.

  4. Rapid response: email, immediacy, and medical humanitarianism in Aceh, Indonesia.

    PubMed

    2014-11-01

    After more than 20 years of sporadic separatist insurgency, the Free Aceh Movement and the Indonesian government signed an internationally brokered peace agreement in August 2005, just eight months after the Indian Ocean tsunami devastated Aceh's coastal communities. This article presents a medical humanitarian case study based on ethnographic data I collected while working for a large aid agency in post-conflict Aceh from 2005 to 2007. In December 2005, the agency faced the first test of its medical and negotiation capacities to provide psychiatric care to a recently amnestied political prisoner whose erratic behavior upon returning home led to his re-arrest and detention at a district police station. I juxtapose two methodological approaches-an ethnographic content analysis of the agency's email archive and field-based participant-observation-to recount contrasting narrative versions of the event. I use this contrast to illustrate and critique the immediacy of the humanitarian imperative that characterizes the industry. Immediacy is explored as both an urgent moral impulse to assist in a crisis and a form of mediation that seemingly projects neutral and transparent transmission of content. I argue that the sense of immediacy afforded by email enacts and amplifies the humanitarian imperative at the cost of abstracting elite humanitarian actors out of local and moral context. As a result, the management and mediation of this psychiatric case by email produced a bureaucratic model of care that failed to account for complex conditions of chronic political and medical instability on the ground.

    The capacity for groups to exhibit collective intelligence is an often-cited advantage of group living. Previous studies have shown that social organisms frequently benefit from pooling imperfect individual estimates. However, in principle, collective intelligence may also emerge from interactions between individuals, rather than from the enhancement of personal estimates. Here, we reveal that this emergent problem solving is the predominant mechanism by which a mobile animal group responds to complex environmental gradients. Robust collective sensing arises at the group level from individuals modulating their speed in response to local, scalar, measurements of light and through social interaction with others. This distributed sensing requires only rudimentary cognition and thus could be widespread across biological taxa, in addition to being appropriate and cost-effective for robotic agents.

    Background: Humanitarian crises are associated with an increase in mental disorders and psychological distress. Despite the emerging consensus on intervention strategies in humanitarian settings, the field of mental health and psychosocial support (MHPSS) in humanitarian settings lacks a consensus-based research agenda. Methods: From August 2009 to February 2010, we contacted policymakers, academic researchers, and humanitarian aid workers, and conducted nine semistructured focus group discussions with 114 participants in three locations (Peru, Uganda, and Nepal), in both the capitals and remote humanitarian settings. Local stakeholders representing a range of academic expertise (psychiatry, psychology, social work, child protection, and medical anthropology) and organizations (governments, universities, nongovernmental organizations, and UN agencies) were asked to identify priority questions for MHPSS research in humanitarian settings, and to discuss factors that hamper and facilitate research. Results: Thematic analyses of transcripts show that participants broadly agreed on prioritized research themes in the following order: (1) the prevalence and burden of mental health and psychosocial difficulties in humanitarian settings, (2) how MHPSS implementation can be improved, (3) evaluation of specific MHPSS interventions, (4) the determinants of mental health and psychological distress, and (5) improved research methods and processes. Rather than differences in research themes across countries, what emerged was a disconnect between different groups of stakeholders regarding research processes: the perceived lack of translation of research findings into actual policy and programs; misunderstanding of research methods by aid workers; different appreciation of the time needed to conduct research; and disputed universality of research constructs. Conclusions: To advance a collaborative research agenda, actors in this field need to bridge the perceived disconnect between

  8. Metacommunity theory explains the emergence of food web complexity.

    2011-11-29

    Food webs are highly complex ecological networks, dynamic in both space and time. Metacommunity models are now at the core of unified theories of biodiversity, but to date they have not addressed food web complexity. Here we show that metacommunity theory can explain the emergence of species-rich food webs with complex network topologies. Our analysis shows that network branching in the food web is maximized at intermediate colonization rates and limited dispersal scales, which also leads to concomitant peaks in species diversity. Increased food web complexity and species diversity are made possible by the structural role played by network branches that are supported by omnivore and generalist feeding links. Thus, in contrast to traditional food web theory, which emphasizes the destabilizing effect of omnivory feeding in closed systems, metacommunity theory predicts that these feeding links, which are commonly observed in empirical food webs, play a critical structural role as food webs assemble in space. As this mechanism functions at the metacommunity level, evidence for its operation in nature will be obtained through multiscale surveys of food web structure. Finally, we apply our theory to reveal the effects of habitat destruction on network complexity and metacommunity diversity.

    2016-11-01

    In a recent edition of Biochemical Journal, Mistry and colleagues described the discovery of a novel protein complex, formed from the epithelial sodium channel (ENaC) and the sodium chloride cotransporter (NCC) [Biochem. J. (2016) Hoover, S.R]. The importance of these two proteins in the regulation of salt balance and blood pressure has long been known, as has their overlapping expression in the distal convoluted tubule of the kidney. The new study by Mistry et al. now demonstrates their physical interaction in the kidney and when heterologously co-expressed. Furthermore, the authors demonstrate some degree of functional co-dependence between ENaC and NCC, with pharmacological inhibition of the latter diminishing activity of the former when the two are co-assembled. This novel and potentially important interaction adds to a growing number of recently identified channel-transporter ('chansporter') complexes, which together constitute an emerging theme in cell signaling.

    We demonstrate that nanoparticle self-assembly can reach the same level of hierarchy, complexity, and accuracy as biomolecules. The precise assembly structures of gold nanoparticles (246 gold core atoms with 80 p-methylbenzenethiolate surface ligands) at the atomic, molecular, and nanoscale levels were determined from x-ray diffraction studies. We identified the driving forces and rules that guide the multiscale assembly behavior. The protecting ligands self-organize into rotational and parallel patterns on the nanoparticle surface via C-Hṡṡṡπ interaction, and the symmetry and density of surface patterns dictate directional packing of nanoparticles into crystals with orientational, rotational, and translational orders. Through hierarchical interactions and symmetry matching, the simple building blocks evolve into complex structures, representing an emergent phenomenon in the nanoparticle system.

    Afghanistan is in the midst of a profound humanitarian crisis resulting primarily from long-standing armed conflict, a devastating drought, and massive population migration. The economy, government, and health care system are in shambles. Currently, as many as 5 million Afghans are in camps either as refugees in neighboring countries or as internally displaced persons within Afghanistan. Much of the rest of the population is in dire need of basic essentials such as food, water, shelter, and basic medical care. Those attempting to carry out humanitarian relief face many daunting challenges, such as reaching remote locations, coping with a dangerous security situation, and working with limited resources. However, there are opportunities in the short run to save many lives and substantially improve the plight of Afghans by carrying out appropriate and effective emergency relief programs. Over the long term, effective medical and public health relief efforts will be an essential part of rehabilitating and rebuilding this devastated country.

    2015-01-01

    Background: Disasters affect close to 400 million people each year. Complex Emergencies (CE) are a category of disaster that affects nearly half of the 400 million and often last for several years. To support the people affected by CE, humanitarian assistance is provided with the aim of saving lives and alleviating suffering. It is widely agreed that funding for this assistance should be needs-based. However, to date, there is no model or set of indicators that quantify and compare needs from one CE to another. In an effort to support needs-based and transparent funding of humanitarian assistance, the aim of this study is to develop a model that distinguishes between levels of severity among countries affected by CE. Methods: In this study, severity serves as a predictor for level of need. The study focuses on two components of severity: vulnerability and exposure. In a literature and Internet search we identified indicators that characterize vulnerability and exposure to CE. Among the more than 100 indicators identified, a core set of six was selected in an expert ratings exercise. Selection was made based on indicator availability and their ability to characterize preexisting or underlying vulnerabilities (four indicators) or to quantify exposure to a CE (two indicators). CE from 50 countries were then scored using a 3-tiered score (Low-Moderate, High, Critical).  Results: The developed model builds on the logic of the Utstein template. It scores severity based on the readily available value of four vulnerability and four exposure indicators. These are 1) GNI per capita, PPP, 2) Under-five mortality rate, per 1 000 live births, 3) Adult literacy rate, % of people ages 15 and above, 4) Underweight, % of population under 5 years, and 5) number of persons and proportion of population affected, and 6) number of uprooted persons and proportion of population uprooted. Conclusion: The model can be used to derive support for transparent, needs-based funding of

    2016-01-01

    Hematopoietic stem cells are formed during embryonic development, and serve as the foundation of the definitive blood program for life. Notch signaling has been well established as an essential direct contributor to HSC specification. However, several recent studies have indicated that the contribution of Notch signaling is complex. HSC specification requires multiple Notch signaling inputs, some received directly by hematopoietic precursors, and others that occur indirectly within neighboring somites. Of note, proinflammatory signals provided by primitive myeloid cells are needed for HSC specification via upregulation of the Notch pathway in hemogenic endothelium. In addition to multiple requirements for Notch activation, recent studies indicate that Notch signaling must subsequently be repressed to permit HSC emergence. Finally, Notch must then be reactivated to maintain HSC fate. In this review, we discuss the growing understanding of the dynamic contributions of Notch signaling to the establishment of hematopoiesis during development. PMID:26586199

  15. Local probe investigation of emergent phenomena in complex oxide heterointerfaces

    NASA Astrophysics Data System (ADS)

    Huang, Mengchen

    Complex oxide heterointerfaces exhibit rich physics as well as many veiled puzzles. LaAlO3/SrTiO3 (LAO/STO) is one of the prototype of such heterointerfaces. In 2004, Ohtomo and Hwang first reported a conducing interface emerged between perovskite oxide insulators LaAlO3 and SrTiO3. Following this seminal discovery, many emergent phenomena like metal-insulator transition, piezoresponse, superconductivity, magnetism, strong spin-orbit coupling and coexistence of superconductivity and magnetism were reported in the fascinating LAO/STO system. However, the origin of the conducting interface is still the subject of intense debate, and the physics behind these emergent phenomena remains a wild space to be explored. My Ph.D. study focused on the emergent phenomena in LAO/STO by using "local probes" -- nanostructures created by conductive atomic force microscope (c-AFM) lithography and the AFM itself. I used piezoresponse force microscope (PFM) to study the electromechanical response in LAO/STO and developed a high-resolution, non-destructive PFM imaging technique to visualize nanostructures at LAO/STO interface. The results indicate that the PFM signal is related to a carrier density mediated interfacial lattice distortion, and surface adsorbates can affect the PFM signal via coupling to the electrons at the interface. I integrated graphene on LAO/STO, created field-effect devices in graphene/LAO/STO and collaborated with Dr. Giriraj Jnawali to investigate the transport properties. The high quality single layer graphene on LAO/STO exhibited the half-integer quantum Hall effect and room temperature weak antilocalization behavior. I performed transport measurements in (110)-oriented LAO/STO to investigate anisotropic quasi one-dimensional superconductivity in nanowires. Based on the results I proposed a plausible explanation related to the Lifshitz transition and anisotropic band structures of nanowires in (110)-oriented LAO/STO. Co-worked with Dr. Keith Brown, I studied

    Sporothrix schenckii, now named the S. schenckii species complex, has largely been known as the etiological agent of sporotrichosis, which is an acute or chronic subcutaneous mycosis of humans and other mammals. Gene sequencing has revealed the following species in the S. schenckii complex: Sporothrix albicans, Sporothrix brasiliensis, Sporothrix globosa, Sporothrix luriei, Sporothrix mexicana and S. schenckii. The increasing number of reports of Sporothrix infection in immunocompromised patients, mainly the HIV-infected population, suggests sporotrichosis as an emerging global health problem concomitant with the AIDS pandemic. Molecular studies have demonstrated a high level of intraspecific variability. Components of the S. schenckii cell wall that act as adhesins and immunogenic inducers, such as a 70-kDa glycoprotein, are apparently specific to this fungus. The main glycan peptidorhamnomannan cell wall component is the only O-linked glycan structure known in S. schenckii. It contains an α-mannobiose core followed by one α-glucuronic acid unit, which may be mono- or di-rhamnosylated. The oligomeric structure of glucosamine-6-P synthase has led to a significant advance in the development of antifungals targeted to the enzyme's catalytic domain in S. schenckii.

  17. Fractal variability: An emergent property of complex dissipative systems

    The patterns of variation of physiologic parameters, such as heart and respiratory rate, and their alteration with age and illness have long been under investigation; however, the origin and significance of scale-invariant fractal temporal structures that characterize healthy biologic variability remain unknown. Quite independently, atmospheric and planetary scientists have led breakthroughs in the science of non-equilibrium thermodynamics. In this paper, we aim to provide two novel hypotheses regarding the origin and etiology of both the degree of variability and its fractal properties. In a complex dissipative system, we hypothesize that the degree of variability reflects the adaptability of the system and is proportional to maximum work output possible divided by resting work output. Reductions in maximal work output (and oxygen consumption) or elevation in resting work output (or oxygen consumption) will thus reduce overall degree of variability. Second, we hypothesize that the fractal nature of variability is a self-organizing emergent property of complex dissipative systems, precisely because it enables the system's ability to optimally dissipate energy gradients and maximize entropy production. In physiologic terms, fractal patterns in space (e.g., fractal vasculature) or time (e.g., cardiopulmonary variability) optimize the ability to deliver oxygen and clear carbon dioxide and waste. Examples of falsifiability are discussed, along with the need to further define necessary boundary conditions. Last, as our focus is bedside utility, potential clinical applications of this understanding are briefly discussed. The hypotheses are clinically relevant and have potential widespread scientific relevance.

    Humanitarian surgical missions can provide much needed care for those who are otherwise unable to receive such care because of limited local health care resources and cost. These missions also offer excellent training opportunities and can be life-changing experiences for those who participate in them. A successful humanitarian surgical mission requires careful planning and coordination and can be challenging for those tasked with the responsibilities to organize and lead these missions. This article addresses many of the issues and challenges encountered when planning and leading humanitarian surgical missions and offers a template to be used by those who take on these challenges.

  19. Complex auditory behaviour emerges from simple reactive steering

    2004-08-01

    The recognition and localization of sound signals is fundamental to acoustic communication. Complex neural mechanisms are thought to underlie the processing of species-specific sound patterns even in animals with simple auditory pathways. In female crickets, which orient towards the male's calling song, current models propose pattern recognition mechanisms based on the temporal structure of the song. Furthermore, it is thought that localization is achieved by comparing the output of the left and right recognition networks, which then directs the female to the pattern that most closely resembles the species-specific song. Here we show, using a highly sensitive method for measuring the movements of female crickets, that when walking and flying each sound pulse of the communication signal releases a rapid steering response. Thus auditory orientation emerges from reactive motor responses to individual sound pulses. Although the reactive motor responses are not based on the song structure, a pattern recognition process may modulate the gain of the responses on a longer timescale. These findings are relevant to concepts of insect auditory behaviour and to the development of biologically inspired robots performing cricket-like auditory orientation.

    2013-01-01

    The Earth, with its core-driven magnetic field, convective mantle, mobile lid tectonics, oceans of liquid water, dynamic climate and abundant life is arguably the most complex system in the known universe. This system has exhibited stability in the sense of, bar a number of notable exceptions, surface temperature remaining within the bounds required for liquid water and so a significant biosphere. Explanations for this range from anthropic principles in which the Earth was essentially lucky, to homeostatic Gaia in which the abiotic and biotic components of the Earth system self-organise into homeostatic states that are robust to a wide range of external perturbations. Here we present results from a conceptual model that demonstrates the emergence of homeostasis as a consequence of the feedback loop operating between life and its environment. Formulating the model in terms of Gaussian processes allows the development of novel computational methods in order to provide solutions. We find that the stability of this system will typically increase then remain constant with an increase in biological diversity and that the number of attractors within the phase space exponentially increases with the number of environmental variables while the probability of the system being in an attractor that lies within prescribed boundaries decreases approximately linearly. We argue that the cybernetic concept of rein control provides insights into how this model system, and potentially any system that is comprised of biological to environmental feedback loops, self-organises into homeostatic states.

    2015-01-01

    Around one century ago, a rice disease characterized mainly by rotting of sheaths was reported in Taiwan. The causal agent was identified as Acrocylindrium oryzae, later known as Sarocladium oryzae. Since then it has become clear that various other organisms can cause similar disease symptoms, including Fusarium sp. and fluorescent pseudomonads. These organisms have in common that they produce a range of phytotoxins that induce necrosis in plants. The same agents also cause grain discoloration, chaffiness, and sterility and are all seed-transmitted. Rice sheath rot disease symptoms are found in all rice-growing areas of the world. The disease is now getting momentum and is considered as an important emerging rice production threat. The disease can lead to variable yield losses, which can be as high as 85%. This review aims at improving our understanding of the disease etiology of rice sheath rot and mainly deals with the three most reported rice sheath rot pathogens: S. oryzae, the Fusarium fujikuroi complex, and Pseudomonas fuscovaginae. Causal agents, pathogenicity determinants, interactions among the various pathogens, epidemiology, geographical distribution, and control options will be discussed. PMID:26697031

    2017-01-01

    ABSTRACT Environmental cues can stimulate a variety of single-cell responses, as well as collective behaviors that emerge within a bacterial community. These responses require signal integration and transduction, which can occur on a variety of time scales and often involve feedback between processes, for example, between growth and motility. Here, we investigate the dynamics of responses of the phototactic, unicellular cyanobacterium Synechocystis sp. PCC6803 to complex light inputs that simulate the natural environments that cells typically encounter. We quantified single-cell motility characteristics in response to light of different wavelengths and intensities. We found that red and green light primarily affected motility bias rather than speed, while blue light inhibited motility altogether. When light signals were simultaneously presented from different directions, cells exhibited phototaxis along the vector sum of the light directions, indicating that cells can sense and combine multiple signals into an integrated motility response. Under a combination of antagonistic light signal regimes (phototaxis-promoting green light and phototaxis-inhibiting blue light), the ensuing bias was continuously tuned by competition between the wavelengths, and the community response was dependent on both bias and cell growth. The phototactic dynamics upon a rapid light shift revealed a wavelength dependence on the time scales of photoreceptor activation/deactivation. Thus, Synechocystis cells achieve exquisite integration of light inputs at the cellular scale through continuous tuning of motility, and the pattern of collective behavior depends on single-cell motility and population growth.

    2009-01-01

    In modern organisms proteins perform a majority of cellular functions, such as chemical catalysis, energy transduction and transport of material across cell walls. Although great strides have been made towards understanding protein evolution, a meaningful extrapolation from contemporary proteins to their earliest ancestors is virtually impossible. In an alternative approach, the origin of water-soluble proteins was probed through the synthesis of very large libraries of random amino acid sequences and subsequently subjecting them to in vitro evolution. In combination with computer modeling and simulations, these experiments allow us to address a number of fundamental questions about the origins of proteins. Can functionality emerge from random sequences of proteins? How did the initial repertoire of functional proteins diversify to facilitate new functions? Did this diversification proceed primarily through drawing novel functionalities from random sequences or through evolution of already existing proto-enzymes? Did protein evolution start from a pool of proteins defined by a frozen accident and other collections of proteins could start a different evolutionary pathway? Although we do not have definitive answers to these questions, important clues have been uncovered. Considerable progress has been also achieved in understanding the origins of membrane proteins. We will address this issue in the example of ion channels - proteins that mediate transport of ions across cell walls. Remarkably, despite overall complexity of these proteins in contemporary cells, their structural motifs are quite simple, with -helices being most common. By combining results of experimental and computer simulation studies on synthetic models and simple, natural channels, I will show that, even though architectures of membrane proteins are not nearly as diverse as those of water-soluble proteins, they are sufficiently flexible to adapt readily to the functional demands arising during

    The need to provide a professionalization process for the humanitarian workforce is well established. Current competency-based curricula provided by existing academically affiliated training centers in North America, the United Kingdom, and the European Union provide a route toward certification. Simulation exercises followed by timely evaluation is one way to mimic the field deployment process, test knowledge of core competences, and ensure that a competent workforce can manage the inevitable emergencies and crises they will face. Through a 2011 field-based exercise that simulated a humanitarian crisis, delivered under the auspices of the World Health Organization (WHO), a competency-based framework and evaluation tool is demonstrated as a model for future training and evaluation of humanitarian providers.

    When British attention was drawn to the issue of leprosy in the Empire, humanitarian organisations rose to take on responsibility for the ‘fight against leprosy’. In an effort to fundraise for a distant cause at a time when hundreds of charities competed for the financial support of British citizens, fundraisers developed propaganda to set leprosy apart from all other humanitarian causes. They drew on leprosy’s relationship with Christianity, its debilitating symptoms, and the supposed vulnerability of leprosy sufferers in order to mobilise Britain’s sense of humanitarian, Christian, and patriotic duty. This article traces the emergence of leprosy as a popular imperial humanitarian cause in modern Britain and analyses the narratives of religion, suffering, and disease that they created and employed in order to fuel their growth and sell leprosy as a British humanitarian cause.

    The Iraq conflict resulted in the largest displacement in the Middle East in recent history, and provision of health services to the displaced population presents a critical challenge. With an increase in the number of people affected by complex emergencies and the number of people displaced in urban settings, the international community must adapt intervention strategies to meet the specific demands and contexts of this population. The study aimed to provide information on food security and livelihoods for Iraqi refugees in Syria and Jordan to inform humanitarian assistance planning. National cross-sectional cluster sample surveys of displaced Iraqi populations displaced were conducted in Jordan (October 2008) and Syria (March 2009). Clusters of ten households were randomly selected using probability-based sampling; a total of 1200 and 813 Iraqi households in Jordan and Syria, respectively, were interviewed about food security and receipt of humanitarian assistance. In Syria, 60% of households reported the household food situation had declined since the arrival period as compared to 46% in Jordan. Food aid receipt was reported by 18.0% of households in Jordan and 90.3% of households in Syria. In Jordan, 10.2% of households received cash assistance and in Syria 25.3% of households received cash assistance. In Jordan, cash assistance was associated with low socioeconomic status, large household size, and UNHCR registration. In Syria, female headed households, Damascus residents, families with children, and those registered with UNHCR were more likely to receive cash assistance. Food insecurity remains a concern among displaced Iraqi households in both Jordan and Syria. Improved targeting of both food and cash assistance and the expansion of cash-based programs could lead to a more effective use of funds and facilitate the implementation of assistance programs that are sustainable in the context of declining funding availability.

  18. Three legacies of humanitarianism in China.

    PubMed

    Hirono, Miwa

    2013-10-01

    The rise of China has altered the context of the international humanitarian community of donors and aid agencies. China is becoming one of the key actors in this grouping, undertaking infrastructure projects in areas in which paramount humanitarian challenges exist. The literature discusses how the Chinese approach differs from that of Western donors, but it does not pay much attention to why China concentrates on its state-centric and infrastructure-based approach. This paper seeks to shed some light on this subject by examining the historical evolution of the concept of humanitarianism in China. This evolution has produced three legacies: (i) the ideal of a well-ordered state; (ii) anti-Western sentiment; and (iii) the notion of comprehensive development based on a human-oriented approach. China's policies and discourses on assistance in humanitarian crises today rest on these three legacies. Traditional donors would be well advised to consider carefully the implications of the Chinese understanding of humanitarianism when engaging with the country.

  19. Violence against children in humanitarian settings: A literature review of population-based approaches.

    2016-03-01

    Children in humanitarian settings are thought to experience increased exposure to violence, which can impair their physical, emotional, and social development. Violence against children has important economic and social consequences for nations as a whole. The purpose of this review is to examine population-based approaches measuring violence against children in humanitarian settings. The authors reviewed prevalence studies of violence against children in humanitarian contexts appearing in peer-reviewed journals within the past twenty years. A Boolean search procedure was conducted in October 2014 of the electronic databases PubMed/Medline and PsychInfo. If abstracts contained evidence of the study's four primary themes--violence, children, humanitarian contexts and population-based measurement--a full document review was undertaken to confirm relevance. Out of 2634 identified articles, 22 met the final inclusion criteria. Across studies, there was varying quality and no standardization in measurement approach. Nine out of 22 studies demonstrated a relationship between conflict exposure and adverse health or mental health outcomes. Among studies that compared rates of violence between boys and girls, boys reported higher rates of physical violence, while girls reported higher rates of sexual violence. Children in infancy and early childhood were found to be among the most under-researched. Ultimately, the body of evidence in this review offers an incomplete picture regarding the prevalence, nature and impact of violence against children in emergencies, demonstrating a weak evidence base for some of the basic assumptions underpinning humanitarian practice. The development of standardized approaches to more rigorously measure violence against children is urgently needed in order to understand trends of violence against children in humanitarian contexts, and to promote children's healthy development and well-being.

  20. Coevolution Drives the Emergence of Complex Traits and Promotes Evolvability

    The evolution of complex organismal traits is obvious as a historical fact, but the underlying causes—including the role of natural selection—are contested. Gould argued that a random walk from a necessarily simple beginning would produce the appearance of increasing complexity over time. Others contend that selection, including coevolutionary arms races, can systematically push organisms toward more complex traits. Methodological challenges have largely precluded experimental tests of these hypotheses. Using the Avida platform for digital evolution, we show that coevolution of hosts and parasites greatly increases organismal complexity relative to that otherwise achieved. As parasites evolve to counter the rise of resistant hosts, parasite populations retain a genetic record of past coevolutionary states. As a consequence, hosts differentially escape by performing progressively more complex functions. We show that coevolution's unique feedback between host and parasite frequencies is a key process in the evolution of complexity. Strikingly, the hosts evolve genomes that are also more phenotypically evolvable, similar to the phenomenon of contingency loci observed in bacterial pathogens. Because coevolution is ubiquitous in nature, our results support a general model whereby antagonistic interactions and natural selection together favor both increased complexity and evolvability.

    From 1900 there have been more than 9800 natural disasters affecting more than 67 million children worldwide. Because of unique physical, developmental, and psychosocial characteristics of children, caring for them during complex emergencies is different to caring for adults. However, planning for these unique physical, developmental, and psychosocial needs has not been well addressed when planning for complex emergencies. Therefore, the purpose of this article is to review those characteristics of children that place them at higher disaster risk, and discuss the preparations necessary to meet their needs before, during, and in the aftermath of complex emergencies.

  2. 'Mind the gap!' rethinking the role of health in the emergency and development divide.

    PubMed

    O'Dempsey, Tim; Munslow, Barry

    2009-10-01

    The 'Emergency Relief-Rehabilitation-Development' model is highly problematic, especially in fragile states which fluctuate in and out of crisis. Lack of definition as to what constitutes a humanitarian emergency and the absence of rules of engagement of NGOs and donors further complicates the problem. Restricted mandates and budgets of institutions and funding bodies lead to gaps in the provision of health services for affected populations. Reducing the gap between emergency and developmental healthcare requires approaching the issue from both sides, recognizing that the emergency-development gap is not a single uniform entity but a complex dynamic of heterogeneous gaps.

  3. Humanitarian aid is never a crime”: humanitarianism and illegality in migrant advocacy.

    2011-01-01

    I analyze the case of humanitarian pro-migrant activists in southern Arizona between 2000 and 2010 to explore how contending groups wield law and legality claims in a dynamic policy environment. Humanitarian activists both evade and engage the law. They appeal to a higher law to elude charges that they are acting illegally, while seeking assurances that their actions are within the law. Law enforcement agents rely on the authority and technical neutrality of the law in redefining humanitarian aid as illegal, while expanding their own claims to carry out humanitarian work. This case study of advocacy on behalf of “illegal” migrants highlights how both activists and those who enforce the law redefine legality in strategic ways.

We provide empirical and theoretical evidence that artificial mummification appeared during a period of increased coastal freshwater availability and marine productivity, which caused an increase in human population size and accelerated the emergence of cultural innovations, as predicted by recent models of cultural and technological evolution. Under a scenario of increasing population size and extreme aridity (with little or no decomposition of corpses) a simple demographic model shows that dead individuals may have become a significant part of the landscape, creating the conditions for the manipulation of the dead that led to the emergence of complex mortuary practices.

  10. Emergence of complex chemistry on an organic monolayer.

    PubMed

    Prins, Leonard J

    2015-07-21

    In many origin-of-life scenarios, inorganic materials, such as FeS or mineral clays, play an important role owing to their ability to concentrate and select small organic molecules on their surface and facilitate their chemical transformations into new molecules. However, considering that life is made up of organic matter, at a certain stage during the evolution the role of the inorganic material must have been taken over by organic molecules. How this exactly happened is unclear, and, indeed, a big gap separates the rudimentary level of organization involving inorganic materials and the complex organization of cells, which are the building blocks of life. Over the past years, we have extensively studied the interaction of small molecules with monolayer-protected gold nanoparticles (Au NPs) for the purpose of developing innovative sensing and catalytic systems. During the course of these studies, we realized that the functional role of this system is very similar to that typically attributed to inorganic surfaces in the early stages of life, with the important being difference that the functional properties (molecular recognition, catalysis, signaling, adaptation) originate entirely from the organic monolayer rather than the inorganic support. This led us to the proposition that this system may serve as a model that illustrates how the important role of inorganic surfaces in dictating chemical processes in the early stages of life may have been taken over by organic matter. Here, we reframe our previously obtained results in the context of the origin-of-life question. The following functional roles of Au NPs will be discussed: the ability to concentrate small molecules and create different local populations, the ability to catalyze the chemical transformation of bound molecules, and, finally, the ability to install rudimentary signaling pathways and display primitive adaptive behavior. In particular, we will show that many of the functional properties of the system

    Martin-Simpson, S; Parkinson, J; Katsou, E

    2017-03-16

    The use of cash transfers and market based programming (CT/MBP) to increase the efficiency and effectiveness of emergency responses is gaining prominence in the humanitarian sector. However, there is a lack of existing indicators and methodologies to monitor activities designed to strengthen water and sanitation (WaSH) markets. Gender and vulnerability markers to measure the impact of such activities on different stakeholders is also missing. This study identifies parameters to monitor, evaluate and determine the added value of utilising CT/MBP to achieve WaSH objectives in humanitarian response. The results of the work revealed that CT/MBP can be used to support household, community and market level interventions to effectively reduce transmission of faeco-oral diseases. Efficiency, effectiveness, sustainability, appropriateness and equity were identified as useful parameters which correlated to widely accepted frameworks against which to evaluate humanitarian action. The parameters were found to be directly applicable to the case of increasing demand and supply of point of use water treatment technology for a) disaster resilience activities, and b) post-crisis response. The need for peer review of the parameters and indicators and pilot measurement in humanitarian contexts was recognised.

  12. Emergence of complex behaviour from simple circuit structures.

    PubMed

    Kaufman, Marcelle; Thomas, René

    2003-02-01

    The set of (feedback) circuits of a complex system is the machinery that allows the system to be aware of the levels of its crucial constituents. Circuits can be identified without ambiguity from the elements of the Jacobian matrix of the system. There are two types of circuits: positive if they comprise an even number of negative interactions, negative if this number is odd. The two types of circuits play deeply different roles: negative circuits are required for homeostasis, with or without oscillations, positive circuits are required for multistationarity, and hence, in biology, for differentiation and memory. In non-linear systems, a circuit can positive or negative (an 'ambiguous circuit', depending on the location in phase space. Full circuits are those circuits (or unions of disjoint circuits) that imply all the variables of the system. There is a tight relation between circuits and steady states. Each full circuit, if isolated, generates steady state(s) whose nature (eigenvalues) is determined by the structure of the circuit. Multistationarity requires the presence of at least two full circuits of opposite Eisenfeld signs, or else, an ambiguous circuit. We show how a significant part of the dynamical behaviour of a system can be predicted by a mere examination of its Jacobian matrix. We also show how extremely complex dynamics can be generated by such simple logical structures as a single (full and ambiguous) circuit.

  13. The TOR Complex: An Emergency Switch for Root Behavior.

    PubMed

    Yokawa, Ken; Baluška, František

    2016-01-01

    Target of rapamycin (TOR) kinase is known to be a controller of cell growth and aging, which determines the fine balance between growth rates and energy availabilities. It has been reported that many eukaryotes express TOR genes. In plants, TOR signaling modifies growth and development in response to a plant's energy status. An example of TOR action can be found in the root apices, which are active organs that explore the soil environment via vigorous growth and numerous tropisms. The exploratory nature of root apices requires a large energy supply for signaling, as well as for cell division and elongation. In the case of negative tropisms, roots must respond quickly to avoid patches of unfavorable soil conditions, again by consuming precious energy reserves. Here we review the current findings on TOR signaling in plants and animals, and propose possible roles for this important complex in driving plant root negative tropisms, particularly during light escape and salt avoidance behavior.

    2005-01-01

    The world is experiencing unprecedented violence and threats of violence, taking the form of complex internal nation-state conflicts, unconventional or guerrilla warfare against established governments, and stateless threats of terrorism by potential biologic, chemical, and nuclear weapons. What happens locally has immediate ramifications internationally. Real and potential health consequences of these events have evoked global concerns and realization that capacities and capabilities to respond to such events require unparalleled integration, coordination, and cooperation of the international community. However, politics and the institutions singular governments form are inherently limited in their objectives and capability to effectively respond. Public health, broadly defined, must be recognized as a security and strategic requirement, one that serves to build a foundation for an international integrated response capacity.

    2016-09-01

    Too often, credible scientific early warning information of increased disaster risk does not result in humanitarian action. With financial resources tilted heavily towards response after a disaster, disaster managers have limited incentive and ability to process complex scientific data, including uncertainties. These incentives are beginning to change, with the advent of several new forecast-based financing systems that provide funding based on a forecast of an extreme event. Given the changing landscape, here we demonstrate a method to select and use appropriate forecasts for specific humanitarian disaster prevention actions, even in a data-scarce location. This action-based forecasting methodology takes into account the parameters of each action, such as action lifetime, when verifying a forecast. Forecasts are linked with action based on an understanding of (1) the magnitude of previous flooding events and (2) the willingness to act "in vain" for specific actions. This is applied in the context of the Uganda Red Cross Society forecast-based financing pilot project, with forecasts from the Global Flood Awareness System (GloFAS). Using this method, we define the "danger level" of flooding, and we select the probabilistic forecast triggers that are appropriate for specific actions. Results from this methodology can be applied globally across hazards and fed into a financing system that ensures that automatic, pre-funded early action will be triggered by forecasts.

    This multidisciplinary review links three areas of legitimate inquiry for practitioners of medicine and public health. The first is occurrences of mass violence or genocide perpetrated against vulnerable populations, with a focus on the failure of national and international mechanisms to prevent or predict such violence. The second is evolving concepts of national sovereignty and an emerging framework in which the imperative to assist vulnerable populations supersedes a state's right to self determination. The last is how medical, public health, and other systems of surveillance and rapid assessment of mass violence can accelerate public awareness and facilitate structured, consistent political decision making to prevent mass violence and to provide international humanitarian assistance.

    PubMed

    Wick, Livia

    2011-01-01

    Discourses and practices surrounding humanitarian organisations have changed over time. This is certainly the case for Palestinian non-governmental organisations, which have followed the structural and ideological transformations observed in local, regional and international contexts. There have been three successive but interlocking generations of groups active in health in Palestine: charitable societies, popular committees, and donor-based entities. Against this background, a village clinic in the West Bank is seen to have gone through various incarnations in the context of an emerging neo-liberal economic, administrative and political environment. Despite the critiques justifiably addressed towards them, non-governmental organisations may in some cases be functionally fluid. Communities and people continue to use them strategically in their relations with states, political groups, individuals and receivers of aid, making them potential networking sites in the context of an ongoing occupation.

    Strohmeier, Hannah; Scholte, Willem F.

    2015-01-01

    Background Working in humanitarian crisis situations is dangerous. National humanitarian staff in particular face the risk of primary and secondary trauma exposure which can lead to mental health problems. Despite this, research on the mental health of national staff is scarce, and a systematic analysis of up-to-date findings has not been undertaken yet. Objective This article reviews the available literature on trauma-related mental health problems among national humanitarian staff. It focuses on the prevalence of selected mental health problems in relation to reference groups; sex and/or gender as predictive factors of mental health problems; and the influence of organization types on mental health problems. Method Three databases were systematically searched for relevant studies published in the English language in peer-reviewed journals. Results Fourteen articles matched the inclusion criteria. Findings suggest that national staff experience mental health problems and the prevalence of posttraumatic stress disorder, depression, and anxiety among this occupation group is mostly similar to or higher than among reference groups. Research on both substance use disorder and suicidal behavior among national staff is particularly scarce. The relation between sex and/or gender and mental health problems among national staff appears to be complex, and organizational staff support seems to be an important determinant for mental health. Conclusion All findings call for increased attention from the humanitarian community and further research on the topic. PMID:26589256

    There is an increasing interest in the humanitarian engineering curriculum, and a service-learning placement could be an important component of such a curriculum. International placements offer some important pedagogical advantages, but also have some practical and ethical limitations. Local community-based placements have the potential to be transformative for both the student and the community, although this potential is not always seen. In order to investigate the role of local placements, qualitative research interviews were conducted. Thirty-two semi-structured research interviews were conducted and analysed, resulting in a distinct outcome space. It is concluded that local humanitarian engineering placements greatly complement international placements and are strongly recommended if international placements are conducted. More importantly it is seen that we are better suited to address the marginalised in our own community, although it is often easier to see the needs of an outside populace.

  2. Horizon scanning for emergence of new viruses: from constructing complex scenarios to online games.

    PubMed

    Gale, P; Breed, A C

    2013-10-01

    Horizon scanning techniques can be developed to identify novel routes and sources for the emergence of viruses in the medium to long term. Central to horizon scanning is prediction of the complex scenarios through which viruses could emerge before they occur. One approach involves 'spidergrams' in which complex scenarios are generated by combining factors randomly selected from different categories of events. Spidergrams provide a framework for how different factors could interact, irrespective of the virus, and also enable testing of combinations not previously considered but which would be 'tested' in nature by a virus. The emergence of viruses through new routes is often related to changes, for example, in environmental and social factors, and the Internet will undoubtedly be used to identify long-term trends for consideration. In addition, online games may provide horizon scanners with suggestions for new routes and strategies that could be used by emerging viruses.

    The current humanitarian crisis in Yemen is unprecedented in many ways. The Yemeni War tragedy is symptomatic of gross failures to recognize, by combatants, existing humanitarian law and the Geneva Convention that have become the new norm in unconventional armed conflicts and are increasingly replicated in Africa, Afghanistan, and other areas of the Middle East with dire consequences on aid workers and the noncombatant population. The health and humanitarian professions must take collective responsibility in calling for all belligerent parties to cease the massacre and commit to guaranteed medical assistance, humanitarian aid, and the free flow of information and respect for the humanitarian principles that protect the neutrality and impartiality of the humanitarian workforce.

    A thermal neutron sensor prototype for Humanitarian Demining has been developed, trying to minimize cost and complexity of the system as required in such application. A (252)Cf source or a sealed-tube neutron generator is employed to produce primary fast neutrons that are thermalized in a moderator designed to optimize the neutron capture reaction yield in buried samples. A description of the sensor, including the performances of the acquisition system based on a Flash ADC card and final tests with explosive simulants are reported. A comparison of the sensor performance when using a radioactive source to that when employing a sealed-tube neutron generator is presented. Limitations and possible applications of this technique are discussed.

    Wide-complex tachycardia is a rare disease entity among patients presenting to the emergency department. However, due to its potential life-threatening nature, emergency clinicians must know how to assess and manage this condition. Wide-complex tachycardia encompasses a range of cardiac dysrhythmias, some of which can be difficult to distinguish and may require specific treatment approaches. This review summarizes the etiology and pathophysiology of wide-complex tachycardia, describes the differential diagnosis, and presents an evidence-based approach to identification of the different types of tachycardias through the use of a thorough history and physical examination, vagal maneuvers, electrocardiography, and adenosine. The treatment options and disposition for patients with various wide-complex tachycardias are also discussed, with attention to special circumstances and select controversial/contemporary topics.

    We investigate the properties of the returns of the main emerging stock markets from Europe by means of complex networks. We transform the series of daily returns into complex networks, and analyze the local properties of these networks with respect to degree distributions, clustering, or average line length. We further use the clustering coefficients as quantities describing the local structure of the network, and approach them by using multifractal analysis. We find evidence of scale-free networks and multifractality of clustering coefficients.

    2010-01-01

    This article examines the role of humanitarian discourse and development in reconfiguring the contemporary culture of empire and its war on terror. It takes as its point of entry the immensely popular biographical tale, Three Cups of Tea, which details how the American mountaineer Greg Mortenson has struggled to counter terrorism in Northern Pakistan through the creation of schools. Even as this text appears to provide a self-critical and humane perspective on terrorism, the article argues that it constructs a misleading narrative of terror in which the realities of Northern Pakistan and Muslim life-worlds are distorted through simplistic tropes of ignorance, backwardness and extremism, while histories of US geopolitics and violence are erased. The text has further facilitated the emergence of a participatory militarism, whereby humanitarian work helps to reinvent the military as a culturally sensitive and caring institution in order to justify and service the project of empire.

    Although most networks in nature exhibit complex topologies, the origins of such complexity remain unclear. We propose a general evolutionary mechanism based on global stability. This mechanism is incorporated into a model of a growing network of interacting agents in which each new agent's membership in the network is determined by the agent's effect on the network's global stability. It is shown that out of this stability constraint complex topological properties emerge in a self-organized manner, offering an explanation for their observed ubiquity in biological networks.

    Outcomes of the World Humanitarian Summit were mixed with some refreshing new directions being endorsed and a lack of systemic reform. The selective agenda and OCHAs lack of success in engaging pre-meeting political participation not only hampered the Summit’s ability to deal with global issues and institutional reform, but also alienated it from leading aid agencies and governments. The UN’s failure to commit to humanitarian principles and global disarray of the humanitarian system indicates the need for extensive reform or a new global humanitarian body. This agency needs to employ a decentralized model to manage aid funds, assume coordination of international responses, resolve civil-military coordination, cater for people affected by both conflict and disasters, and professionalize the humanitarian career.  PMID:27679738

    The robust plant cell wall polysaccharide-degrading properties of anaerobic bacteria are harnessed within elegant, marcomolecular assemblages called cellulosomes, in which proteins of complementary activities amass on scaffold protein networks. Research efforts have focused and continue to focus on providing detailed mechanistic insights into cellulosomal complex assembly, topology, and function. The accumulated information is expanding our fundamental understanding of the lignocellulosic biomass decomposition process and enhancing the potential of engineered cellulosomal systems for biotechnological purposes. Ongoing biochemical studies continue to reveal unexpected functional diversity within traditional cellulase families. Genomic, proteomic, and functional analyses have uncovered unanticipated cellulosomal proteins that augment the function of the native and designer cellulosomes. In addition, complementary structural and computational methods are continuing to provide much needed insights on the influence of cellulosomal interdomain linker regions on cellulosomal assembly and activity.

    2015-01-01

    Natural and man-made catastrophes have caused significant destruction and loss of lives throughout human history. Disasters accompany a wide variety of events with multiple causes and consequences often leading to a cascade of related events. African continent has not been spared of these events. A new phenomenon in the continent is terrorism that is fuelled by globalization of arms trade and has contributed significantly to escalation of conflicts in sub-Saharan Africa (SSA) resulting in complex emergencies and destruction of socioeconomic structures. The aim of this paper is to review relevant papers on management of disasters and complex emergencies in Africa and the challenges and constraints against the background of a weakened health system. Systematic search of published literature was conducted between 1990 and 2013. Grey literature (technical reports, government documents), published peer review journals, abstracts, relevant books and internet articles were reviewed. The review revealed that the frequency of both natural and man-made disasters in Africa is escalating. Complex emergencies are also on the increase since the Rwandan crisis in 1994. The impact of these events has overstretched and overwhelmed the health care system that is least prepared to handle and cope with the surge capacity and also render normal services. In conclusion, there is an urgent need for national emergency agencies/departments across Africa to develop a robust emergency preparedness and response plan. Every hospital most have a disaster management committee with flexible disaster management plan to respond to these catastrophes. There is a need for curriculum review in tertiary institutions across SSA to introduce and or expand training in disaster management.

    Griffith, Elizabeth C; Tuck, Adrian F; Vaida, Veronica

    2012-12-18

    The prebiotic conversion of simple organic molecules into complex biopolymers necessary for life can only have emerged on a stage set by geophysics. The transition between "prebiotic soup," the diverse mixture of small molecules, and complex, self-replicating organisms requires passing through the bottleneck of fundamental chemistry. In this Account, we examine how water-air interfaces, namely, the surfaces of lakes, oceans, and atmospheric aerosols on ancient Earth, facilitated the emergence of complex structures necessary for life. Aerosols are liquid or solid suspensions in air with a broad, power law size distribution. Collectively, these globally distributed atmospheric particles have an enormous surface area. Organic films at the interface between water and air offer advantages for biomolecular synthesis compared with the bulk and can simultaneously participate in the folding of biopolymers into primitive enclosed structures. We survey the advantages of the water-air interface for prebiotic chemistry in a geophysical context from three points of view. We examine the formation of biopolymers from simple organic precursors and describe the necessity and availability of enclosures. In addition, we provide a statistical mechanical approach to natural selection and emergence of complexity that proposes a link between these molecular mechanisms and macroscopic scales. Very large aerosol populations were ubiquitous on ancient Earth, and the surfaces of lakes, oceans, and atmospheric aerosols would have provided an auspicious environment for the emergence of complex structures necessary for life. These prebiotic reactors would inevitably have incorporated the products of chemistry into their anhydrous, two-dimensional organic films in the three-dimensional fluids of the gaseous atmosphere and the liquid ocean. The untrammeled operation of natural selection on these aerosols provided the likely location where condensation reactions could form biopolymers by

Analyzing the evolution of the photospheric magnetic flux and the coronal structure, we find that the flux emergence triggered the eruption by interaction with overlying flux in a non-standard way. The new flux neither had the opposite orientation nor a location near the polarity inversion line, which are favorable for strong reconnection with the arcade flux under which it emerged. Moreover, its flux content remained significantly smaller than that of the arcade ({≈} 40 %). However, a loop system rooted in the trailing active region ran in part under the arcade between the active regions, passing over the site of flux emergence. The reconnection with the emerging flux, leading to a series of jet emissions into the loop system, caused a strong but confined rise of the loop system. This lifted the arcade between the two active regions, weakening its downward tension force and thus destabilizing the considerably sheared flux under the arcade. The complex event was also associated with supporting precursor activity in an enhanced network near the active regions, acting on the large-scale overlying flux, and with two simultaneous confined flares within the active regions.

  2. Humanitarian engineering in the engineering curriculum

    Vandersteen, Jonathan Daniel James

    There are many opportunities to use engineering skills to improve the conditions for marginalized communities, but our current engineering education praxis does not instruct on how engineering can be a force for human development. In a time of great inequality and exploitation, the desire to work with the impoverished is prevalent, and it has been proposed to adjust the engineering curriculum to include a larger focus on human needs. This proposed curriculum philosophy is called humanitarian engineering. Professional engineers have played an important role in the modern history of power, wealth, economic development, war, and industrialization; they have also contributed to infrastructure, sanitation, and energy sources necessary to meet human need. Engineers are currently at an important point in time when they must look back on their history in order to be more clear about how to move forward. The changing role of the engineer in history puts into context the call for a more balanced, community-centred engineering curriculum. Qualitative, phenomenographic research was conducted in order to understand the need, opportunity, benefits, and limitations of a proposed humanitarian engineering curriculum. The potential role of the engineer in marginalized communities and details regarding what a humanitarian engineering program could look like were also investigated. Thirty-two semi-structured research interviews were conducted in Canada and Ghana in order to collect a pool of understanding before a phenomenographic analysis resulted in five distinct outcome spaces. The data suggests that an effective curriculum design will include teaching technical skills in conjunction with instructing about issues of social justice, social location, cultural awareness, root causes of marginalization, a broader understanding of technology, and unlearning many elements about the role of the engineer and the dominant economic/political ideology.

    Mass spectrometry (MS) is a powerful tool for determining the mass of biomolecules with high accuracy and sensitivity. MS performed under so-called “native conditions” (native MS) can be used to determine the mass of biomolecules that associate noncovalently. Here we review the application of native MS to the study of protein−ligand interactions and its emerging role in elucidating the structure of macromolecular assemblies, including soluble and membrane protein complexes. Moreover, we discuss strategies aimed at determining the stoichiometry and topology of subunits by inducing partial dissociation of the holo-complex. We also survey recent developments in "native top-down MS", an approach based on Fourier Transform MS, whereby covalent bonds are broken without disrupting non-covalent interactions. Given recent progress, native MS is anticipated to play an increasingly important role for researchers interested in the structure of macromolecular complexes. PMID:25676284

    Networks with complex topology describe systems as diverse as the cell or the World Wide Web. The analysis of the metabolic and protein network of various organisms show that cells and complex man-made networks, such as the Internet or the world wide web, share the same large-scale topology. In the past few years we have learned that the emergence of these networks is driven by self-organizing processes that are governed by simple but generic laws, that can be captured using the tools of statistical mechanics. The goal of the talk is to briefly review these advances, aiming to uncover the organizing principles that govern the topology of complex networks.

    Our practice in a humanitarian (or crisis) context differs from what we experience in daily practice. There are several reasons for this. First, the diseases encountered are sometimes unfamiliar, such as sequelae of noma, or the presentation of familiar diseases may be unusual, such as facial malformations seen at a late stage. Secondly, these missions take place in developing countries, and consequently, evaluation and anticipation of possible malnutrition should be considered, especially because facial diseases themselves may be responsible for nutritional problems. Lastly, conditions are often difficult, occurring in an unusual environment, and we sometimes have to face communication and equipment problems. The goal of our work, based on a 15-year experience (in Bamako and Mopti with the Association "Santé et Développement", and in Ouagadougou with the organization "Les enfants du noma") and the analysis of literature, is to point out these features and maybe to be helpful to others.

    Training and planning for stability, security, transition, and reconstruction, to include humanitarian and civic assistance activities, has taken on new importance for today's military forces. Deployed medical forces providing medical care to local populations are presented with the challenge of limited resources, complex public health needs, and complex cultural and linguistic barriers to care. In this article, we review some of the clinical situations commonly encountered during these operations and provide an evidence-based rationale for proposed courses of action. This report is timely given expanding operations in Afghanistan and the stand-up of the U.S. African Command (AFRICOM).

  7. Humanitarian mine detection by acoustic resonance

    Kercel, S.W.

    1998-03-01

    The JASON Committee at MITRE Corp. was tasked by DARPA to inquire into suitable technologies for humanitarian mine detection. Acoustic resonance was one of the very few technologies that the JASONs determined might be promising for the task, but was as yet unexplored at the time that they conducted their inquiry. The objective of this Seed Money investigation into acoustic resonance was to determine if it would be feasible to use acoustic resonance to provide an improvement to present methods for humanitarian mine detection. As detailed in this report, acoustic resonance methods do not appear to be feasible for this task. Although acoustic resonant responses are relatively easy to detect when they exist, they are very difficult to excite by the non-contact means that must be used for buried objects. Despite many different attempts, this research did not discover any practical means of using sound to excite resonant responses in objects known to have strong resonances. The shaker table experiments did see an effect that might be attributable to the resonance of the object under test, but the effect was weak, and exploited the a priori knowledge of the resonant frequency of the object under test to distinguish it from the background. If experiments that used objects known to have strong acoustic resonances produced such marginal results, this does not seem to be a practical method to detect objects with weak resonances or non-existent resonances. The results of this work contribute to the ORNL countermine initiative. ORNL is exploring several unconventional mine detection technologies, and is proposed to explore others. Since this research has discovered some major pitfalls in non-metallic mine detection, this experience will add realism to other strategies proposed for mine detection technologies. The experiment provided hands-on experience with inert plastic mines under field conditions, and gives ORNL additional insight into the problems of developing practical

    This study investigates the strategic antecedents of operational agility in humanitarian logistics. It began by identifying the particular actions to be taken at the strategic level of a humanitarian organisation to support field-level agility. Next, quantitative data (n=59) were collected on four strategic-level capabilities (being purposeful, action-focused, collaborative, and learning-oriented) and on operational agility (field responsiveness and flexibility). Using a quantitative analysis, the study tested the relationship between organisational capacity building and operational agility and found that the four strategic-level capabilities are fundamental building blocks of agility. Collectively they account for 52 per cent of the ability of humanitarian logisticians to deal with ongoing changes and disruptions in the field. This study emphasises the need for researchers and practitioners to embrace a broader perspective of agility in humanitarian logistics. In addition, it highlights the inherently strategic nature of agility, the development of which involves focusing simultaneously on multiple drivers.

  10. Ethics and images of suffering bodies in humanitarian medicine.

    PubMed

    Calain, Philippe

    2013-12-01

    Media representations of suffering bodies from medical humanitarian organisations raise ethical questions, which deserve critical attention for at least three reasons. Firstly, there is a normative vacuum at the intersection of medical ethics, humanitarian ethics and the ethics of photojournalism. Secondly, the perpetuation of stereotypes of illness, famine or disasters, and their political derivations are a source of moral criticism, to which humanitarian medicine is not immune. Thirdly, accidental encounters between members of the health professions and members of the press in the humanitarian arena can result in misunderstandings and moral tension. From an ethics perspective the problem can be specified and better understood through two successive stages of reasoning. Firstly, by applying criteria of medical ethics to the concrete example of an advertising poster from a medical humanitarian organisation, I observe that media representations of suffering bodies would generally not meet ethical standards commonly applied in medical practice. Secondly, I try to identify what overriding humanitarian imperatives could outweigh such reservations. The possibility of action and the expression of moral outrage are two relevant humanitarian values which can further be spelt out through a semantic analysis of 'témoignage' (testimony). While the exact balance between the opposing sets of considerations (medical ethics and humanitarian perspectives) is difficult to appraise, awareness of all values at stake is an important initial standpoint for ethical deliberations of media representations of suffering bodies. Future pragmatic approaches to the issue should include: exploring ethical values endorsed by photojournalism, questioning current social norms about the display of suffering, collecting empirical data from past or potential victims of disasters in diverse cultural settings, and developing new canons with more creative or less problematic representations of

    2011-01-01

    It is now widely accepted that at an early stage in the evolution of life an RNA world arose, in which RNAs both served as the genetic material and catalyzed diverse biochemical reactions. Then, proteins have gradually replaced RNAs because of their superior catalytic properties in catalysis over time. Therefore, it is important to investigate how primitive functional proteins emerged from RNA world, which can shed light on the evolutionary pathway of life from RNA world to the modern world. In this work, we proposed that the emergence of most primitive functional proteins are assisted by the early primitive nucleotide cofactors, while only a minority are induced directly by RNAs based on the analysis of RNA-protein complexes. Furthermore, the present findings have significant implication for exploring the composition of primitive RNA, i.e., adenine base as principal building blocks. PMID:21789260

    The MACHWIND model (Meyers 1989) is one of a group of models used to compute regional wind fields from tower wind data and/or vertical wind profiles. The wind fields are in turn used to calculate atmospheric diffusion, to guide emergency responses. MACHWIND has performed acceptably in uniform terrain under steady, well mixed conditions. However, extension of the model to more complex situations is problematic. In coastal, hilly terrain like that near Vandenberg Air Force Base (VAFB) in southern California, calculations of the wind field can be enhanced significantly by several modifications to the original code. This report highlights the structure of MACHWIND and details the enhancements that were implemented.

While recognizing that technical expertise is important for effective provision of aid, the author stresses that humanitarianism requires more than technology. He also warns that collecting the funds necessary for relief operations must not lead to commercial-style marketing of humanitarian assistance. Similarly he cautions that the targets for humanitarian action should not be determined by television pictures. In conclusion the author advocates responsible administration of humanitarian programs.

    Handoffs are known to increase the risk of medical error and adverse events. Few electronic tools can support this process effectively, however. Our objective was to describe the relationship between clinical complexity, diagnostic uncertainty, fit with illness script and the content of case presentations by physicians. We observed the handoff of care for150 patients during eleven shift changes at a large urban emergency department (ED). Results indicate that as uncertainty about diagnosis and perceived illness script increased, more descriptive detail was conveyed to the incoming physicians. Physicians were concerned primarily with creating a shared mental model of a patient's clinical state and with describing the expected path to disposition rather than simply passing on data and findings. Electronic tools for ED handoffs should allow adjustment of structure and content to capture complexity and uncertainty appropriately without requiring extra effort for more routine cases that better fit to more standard narratives.

    Erwin Schrödinger defined life not only as a "self-reproducing" aperiodic crystal of DNA coding for proteins but within the context of living entities increasing their order by dissipating matter/energy gradients to maintain themselves away from equilibirium. Since then most definitions of life have focused on the former. But living cells do more than replicate their DNA. Cells also have membrane barriers across which metabolites must move, via which energy transduction as well as information processing occurs, and within which metabolic transformation occurs. An approach of complex systems dynamics, including nonequilibrium thermodynamics, may provide a more robust approach for defining life than a "naked replicator" at the origin of life. The crucial issue becomes the process of emergence of life from pre-biotic chemistry, concomitant with the emergence of function, information, and semiosis. Living entities can be viewed as bounded, informed autocatalytic cycles feeding off matter/energy gradients, exhibiting agency, capable of growth, reproduction, and evolution. Understanding how life might have emerged should sharpen our definition of what life is.

    The spontaneous emergence of coherent behavior through synchronization plays a key role in neural function, and its anomalies often lie at the basis of pathologies. Here we employ a parsimonious (mesoscopic) approach to study analytically and computationally the synchronization (Kuramoto) dynamics on the actual human-brain connectome network. We elucidate the existence of a so-far-uncovered intermediate phase, placed between the standard synchronous and asynchronous phases, i.e. between order and disorder. This novel phase stems from the hierarchical modular organization of the connectome. Where one would expect a hierarchical synchronization process, we show that the interplay between structural bottlenecks and quenched intrinsic frequency heterogeneities at many different scales, gives rise to frustrated synchronization, metastability, and chimera-like states, resulting in a very rich and complex phenomenology. We uncover the origin of the dynamic freezing behind these features by using spectral graph theory and discuss how the emerging complex synchronization patterns relate to the need for the brain to access –in a robust though flexible way– a large variety of functional attractors and dynamical repertoires without ad hoc fine-tuning to a critical point.

    2015-05-01

    Self-organization in a voltage-driven nonequilibrium system, consisting of conducting beads immersed in a viscous medium, gives rise to a dynamic tree structure that exhibits wormlike motion. The complex motion of the beads driven by the applied field, the dipole-dipole interaction between the beads and the hydrodynamic flow of the viscous medium, results in a time evolution of the tree structure towards states of lower resistance or higher dissipation and thus higher rates of entropy production. Thus emerges a remarkably organismlike energy-seeking behavior. The dynamic tree structure draws the energy needed to form and maintain its structure, moves to positions at which it receives more energy, and avoids conditions that lower available energy. It also is able to restore its structure when damaged, i.e., it is self-healing. The emergence of energy-seeking behavior in a nonliving complex system that is extremely simple in its construct is unexpected. Along with the property of self-healing, this system, in a rudimentary way, exhibits properties that are analogous to those we observe in living organisms. Thermodynamically, the observed diverse behavior can be characterized as end-directed evolution to states of higher rates of entropy production.

    The treatment of hunger strikers is always contentious, chaotic and complex. The management is particularly difficult for health professionals as it raises unprecedented clinical, ethical, moral, humanitarian, and legal questions. There are never any easy answers. The current situation of prisoners from the Iraq and Afghanistan Wars currently at the Guantanamo Bay Detention Center in Cuba demands unprecedented transparency, accountability and multilevel coordination to ensure that the rights of the strikers are properly met. There are scant references available in the scientific literature on the emergency management of these tragedies. This historical perspective documents the complex issues faced by emergency physicians in Hong Kong surrounding refugee camp asylum seekers from Vietnam in 1994 and is offered as a useful adjunct in understanding the complex issues faced by emergency health providers and managers.

This study aimed to document the current institutional experiences and capacities related to RHHS. Materials and Methods Descriptive study using an online questionnaire tool. Results Respondents represented 82 institutions from 48 countries, of which two-thirds originated from low-and middle-income countries. RHHS work was found not to be restricted to humanitarian agencies (25%), but was also embraced by development organizations (25%) and institutions with dual humanitarian and development mandates (50%). Agencies reported working with refugees (81%), internally-displaced (87%) and stateless persons (20%), in camp-based settings (78%), and in urban (83%) and rural settings (78%). Sixty-eight percent of represented institutions indicated having an RHHS-related policy, 79% an accountability mechanism including humanitarian work, and 90% formal partnerships with other institutions. Seventy-three percent reported routinely appointing RH focal points to ensure coordination of RHHS implementation. There was reported progress in RHHS-related disaster risk reduction (DRR), emergency management and coordination, delivery of the Minimum Initial Services Package (MISP) for RH, comprehensive RH services in post-crisis/recovery situations, gender mainstreaming, and community-based programming. Other reported institutional areas of work included capacity development, program delivery, advocacy/policy work, followed by research and donor activities. Except for abortion-related services, respondents cited improved efforts in advocacy, capacity development and technical support in their institutions for RHHS to address clinical services, including maternal and newborn health, sexual violence prevention and response, HIV prevention, management

    2007-11-01

    Humanitarian psychological support as an organized field is relatively young. Pioneers in the field were involved primarily in providing psychological support to refugees and internally displaced persons in conflict and nonconflict situations. This article describes basic principles for the design of psychological support programs and interventions. The International Federation of Red Cross and Red Crescent Societies (IFRC) began a psychological support program in 1991. The IFRC chose psychological first aid as its model for implementation in developing countries. Psychological first aid fits all the principles for psychological support program design and is adapted to individual communities. The first generation of psychological support programs differed dramatically depending on the countries in which they were developed. A second generation of psychological support programs evolved in response to the earthquake/tsunami of December 26, 2004. The Inter-Agency Standing Committee international guidelines consolidated the advances of second-generation programs and provided a clear indication of the wide acceptance of the importance of psychological support. A glimpse is provided of the third generation of psychological support programs, and an admonition is made for a more empirical evaluation of the effectiveness of interventions.

    Various physical, social, and biological systems generate complex fluctuations with correlations across multiple time scales. In physiologic systems, these long-range correlations are altered with disease and aging. Such correlated fluctuations in living systems have been attributed to the interaction of multiple control systems; however, the mechanisms underlying this behavior remain unknown. Here, we show that a number of distinct classes of dynamical behaviors, including correlated fluctuations characterized by 1/f scaling of their power spectra, can emerge in networks of simple signaling units. We found that, under general conditions, complex dynamics can be generated by systems fulfilling the following two requirements, (i) a “small-world” topology and (ii) the presence of noise. Our findings support two notable conclusions. First, complex physiologic-like signals can be modeled with a minimal set of components; and second, systems fulfilling conditions i and ii are robust to some degree of degradation (i.e., they will still be able to generate 1/f dynamics).

    Gallagher, D; Forbes, S; Fagan, P W

    1986-01-01

    The Refugee Act of 1980 is the 1st comprehensive legislation on the admission of refugees to the US; in the 5+ years since its enactment, over 500,000 refugees from more than 25 countries have been admitted to the US. This report assesses the effectiveness of the law in achieving its objectives in making and implementing decisions about the admission of refugees. The objectives of the Act include 1) a desire for a humanitarian response to refugee emergencies and a desire for control over that response, 2) a concern that ideological and geographic restrictions on refugee admissions be removed, and 3) a desire to balance international concerns and domestic impacts in making decisions on refugee admissions. The authors conclude that the refugee program does not serve the broad humanitarian purposes of previous parole programs, due to its stringent review requirements. The formal Congressional Consultations on refugee numbers should be rescheduled to allow regular Congressional input. The program needs a contingency budget for changing situations. The program needs more input from nongovernmental agencies and information sources. Recommendations on refugee admission numbers and allocations have not been well substantiated. Determinations as to which refugees are of "special humanitarian concern" are made solely on the basis of nationality; these decisions should also incorporate other factors. Admissions priorities are generally based on ties to this country, but this makes the refugee program a surrogate immigration program. Although the application of the refugee definition is difficult in practice, it forms the essence of the admission process. US staff must be trained to make these decisions; indecisiveness must not be allowed to jeopardize refugees.

    2016-12-01

    In the last twenty years, a conversation has emerged in the evaluation field about the potential of systems thinking and complexity science (STCS) to transform the practice of evaluating social interventions. Documenting and interpreting this conversation are necessary to advance our understanding of the significance of using STCS in planning, implementing, and evaluating social interventions. Guided by a generic framework for evaluation practice, this paper reports on an inter-disciplinary literature review and argues that STCS raises some new ways of thinking about and carrying out the following six activities: 1) supporting social problem solving; 2) framing interventions and contexts; 3) selecting and using methods; 4) engaging in valuing; 5) producing and justifying knowledge; and 6) facilitating use. Following a discussion of these issues, future directions for research and practice are suggested.

In the context of our research project, gathering, formalising and exploiting all the knowledge and information about a given crisis situation is a critical requirement. This paper presents some research results concerning this specific topic: from a theoretical point of view, the generic dimensions of crisis characterisation are defined, while from a technical point of view, we describe a software solution able to collect that knowledge (based on meta-models and ontologies). This is used to confront the characteristics of the situation (context) with characteristics of the resources (relief system) in order to design a suitable response. Finally, an illustrative example concerning a crash between a tanker truck and a train is described.

    Color patterns of bird plumage affect animal behavior and speciation. Diverse patterns are present in different species and within the individual. Here, we study the cellular and molecular basis of feather pigment pattern formation. Melanocyte progenitors are distributed as a horizontal ring in the proximal follicle, sending melanocytes vertically up into the epithelial cylinder, which gradually emerges as feathers grow. Different pigment patterns form by modulating the presence, arrangement, or differentiation of melanocytes. A layer of peripheral pulp further regulates pigmentation via patterned agouti expression. Lifetime feather cyclic regeneration resets pigment patterns for physiological needs. Thus, the evolution of stem cell niche topology allows complex pigment patterning through combinatorial co-option of simple regulatory mechanisms.

  12. Mechanisms and dynamics of cooperation and competition emergence in complex networked systems

    NASA Astrophysics Data System (ADS)

    Gianetto, David A.

    Cooperative behavior is a pervasive phenomenon in human interactions and yet how it can evolve and become established, through the selfish process of natural selection, is an enduring puzzle. These behaviors emerge when agents interact in a structured manner; even so, the key structural factors that affect cooperation are not well understood. Moreover, the literature often considers cooperation a single attribute of primitive agents who do not react to environmental changes but real-world actors are more perceptive. The present work moves beyond these assumptions by evolving more realistic game participants, with memories of the past, on complex networks. Agents play repeated games with a three-part Markovian strategy that allows us to separate the cooperation phenomenon into trust, reciprocity, and forgiveness characteristics. Our results show that networks matter most when agents gain the most by acting in a selfish manner, irrespective of how much they may lose by cooperating; since the context provided by neighborhoods inhibits greedy impulses that agents otherwise succumb to in isolation. Network modularity is the most important driver of cooperation emergence in these high-stakes games. However, modularity fails to tell the complete story. Modular scale-free graphs impede cooperation when close coordination is required, partially due to the acyclic nature of scale-free network models. To achieve the highest cooperation in diverse social conditions, both high modularity, low connectivity within modules, and a rich network of long cycles become important. With these findings in hand, we study the influence of networks on coordination and competition within the federal health care insurance exchange. In this applied study, we show that systemic health care coordination is encouraged by the emergent insurance network. The network helps underpin the viability of the exchange and provides an environment of stronger competition once a critical-mass of insurers have

  13. A systematic review of prevalence studies of gender-based violence in complex emergencies.

    Current methods to estimate the incidence of gender-based violence in complex emergencies tend to rely on nonprobability samples. Population-based monitoring is undertaken relatively infrequently. This article provides a systematic review of published literature that represents attempts to quantify the magnitude of gender-based violence in emergency settings. Searches adopted a Boolean procedure, which led to initial selection of material that was then reviewed against set criteria. Only 10 studies met the final criteria for inclusion. Intimate partner violence, physical violence, and rape were the three categories of violence most frequently measured. Rates of intimate partner violence tended to be quite high across all of the studies-much higher than most of the rates of wartime rape and sexual violence perpetrated by individuals outside of the home. Direct comparisons of rates of violence were hindered by different case definitions, recall periods, and other methodological features. Recommendations for future studies are offered based on lessons learned from the studies reviewed.

  14. Emerging Major Histocompatibility Complex Class I-Related Functions of NLRC5.

    Recent evidence demonstrates a key role for the nucleotide-binding oligomerization domain-like receptor (NLR) family member NLRC5 (NLR family, CARD domain containing protein 5) in the transcriptional regulation of major histocompatibility complex (MHC) class I and related genes. Detailed information on NLRC5 target genes in various cell types and conditions is emerging. Thanks to its analogy to CIITA (class II major MHC transactivator), a NLR family member known for over 20 years to be the master regulator of MHC class II gene transcription, also the molecular mechanisms underlying NLRC5 function are being rapidly unraveled. MHC class I molecules are crucial in regulating innate and adaptive cytotoxic responses. Whereas CD8(+) T cells detect antigens presented on MHC class I molecules by infected or transformed cells, natural killer (NK) lymphocytes eliminate target cells with downregulated MHC class I expression. Data uncovering the relevance of NLRC5 in homeostasis and activity of these two lymphocyte subsets have been recently reported. Given the importance of CD8(+) T and NK cells in controlling infection and cancer, it is not surprising that NLRC5 is also starting to emerge as a central player in these diseases. This chapter summarizes and discusses novel insights into the molecular mechanisms underlying NLRC5 activity and its relevance to pathological conditions. A thorough understanding of both aspects is essential to evaluate the clinical significance and therapeutic potential of NLRC5.

    We have developed a general scenario of prebiotic physicochemical evolution during the Earth's Hadean eon and reviewed the relevant literature. We suggest that prebiotic chemical evolution started in microspaces with membranous walls, where external temperature and osmotic gradients were coupled to free-energy gradients of potential chemical reactions. The key feature of this scenario is the onset of an emergent evolutionary transition within the microspaces that is described by the model of complex vectorial chemistry. This transition occurs at average macromolecular crowding of 20 to 30% of the cell volume, when the ranges of action of stabilizing colloidal forces (screened electrostatic forces, hydration, and excluded volume forces) become commensurate. Under these conditions, the macromolecules divide the interior of microspaces into dynamically crowded macromolecular regions and topologically complementary electrolyte pools. Small ions and ionic metabolites are transported vectorially between the electrolyte pools and through the (semiconducting) electrolyte pathways of the crowded macromolecular regions from their high electrochemical potential (where they are biochemically produced) to their lower electrochemical potential (where they are consumed). We suggest a sequence of tentative transitions between major evolutionary periods during the Hadean eon as follows: (i) the early water world, (ii) the appearance of land masses, (iii) the pre-RNA world, (iv) the onset of complex vectorial chemistry, and (v) the RNA world and evolution toward Darwinian thresholds. We stress the importance of high ionic strength of the Hadean ocean (short Debye's lengths) and screened electrostatic interactions that enabled the onset of the vectorial structure of the cytoplasm and the possibility of life's emergence.

    This paper presents the reflections of the authors on the differences between the language and the approach of practitioners and academics to humanitarian logistics problems. Based on a long-term project on fleet management in the humanitarian sector, involving both large international humanitarian organisations and academics, it discusses how differences in language and approach to such problems may create a lacuna that impedes trust. In addition, the paper provides insights into how academic research evidence adapted to practitioner language can be used to bridge the gap. When it is communicated appropriately, evidence strengthens trust between practitioners and academics, which is critical for long-term projects. Once practitioners understand the main trade-offs included in academic research, they can supply valuable feedback to motivate new academic research. Novel research problems promote innovation in the use of traditional academic methods, which should result in a win-win situation: relevant solutions for practice and advances in academic knowledge.

  18. Emergence, institutionalization and renewal: Rhythms of adaptive governance in complex social-ecological systems.

    2016-01-01

    Adaptive governance provides the capacity for environmental managers and decision makers to confront variable degrees of uncertainty inherent to complex social-ecological systems. Current theoretical conceptualizations of adaptive governance represent a series of structures and processes best suited for either adapting or transforming existing environmental governance regimes towards forms flexible enough to confront rapid ecological change. As the number of empirical examples of adaptive governance described in the literature grows, the conceptual basis of adaptive governance remains largely under theorized. We argue that reconnecting adaptive governance with foundational concepts of ecological resilience-specifically Panarchy and the adaptive cycle of complex systems-highlights the importance of episodic disturbances and cross-scale interactions in triggering reorganizations in governance. By envisioning the processes of adaptive governance through the lens of Panarchy, scholars and practitioners alike will be better able to identify the emergence of adaptive governance, as well as take advantage of opportunities to institutionalize this type of governance in pursuit of sustainability outcomes. The synergistic analysis of adaptive governance and Panarchy can provide critical insight for analyzing the role of social dynamics during oscillating periods of stability and instability in social-ecological systems. A deeper understanding of the potential for cross-scale interactions to shape adaptive governance regimes may be useful as society faces the challenge of mitigating the impacts of global environmental change.

    The linking of North and South America by the Isthmus of Panama had major impacts on global climate, oceanic and atmospheric currents, and biodiversity, yet the timing of this critical event remains contentious. The Isthmus is traditionally understood to have fully closed by ca. 3.5 million years ago (Ma), and this date has been used as a benchmark for oceanographic, climatic, and evolutionary research, but recent evidence suggests a more complex geological formation. Here, we analyze both molecular and fossil data to evaluate the tempo of biotic exchange across the Americas in light of geological evidence. We demonstrate significant waves of dispersal of terrestrial organisms at approximately ca. 20 and 6 Ma and corresponding events separating marine organisms in the Atlantic and Pacific oceans at ca. 23 and 7 Ma. The direction of dispersal and their rates were symmetrical until the last ca. 6 Ma, when northern migration of South American lineages increased significantly. Variability among taxa in their timing of dispersal or vicariance across the Isthmus is not explained by the ecological factors tested in these analyses, including biome type, dispersal ability, and elevation preference. Migration was therefore not generally regulated by intrinsic traits but more likely reflects the presence of emergent terrain several millions of years earlier than commonly assumed. These results indicate that the dramatic biotic turnover associated with the Great American Biotic Interchange was a long and complex process that began as early as the Oligocene–Miocene transition.

    Crown ethers provide a valuable benchmark for the comprehension of molecular recognition mediated by inclusion complexes. One of the most relevant crown ethers, 18-crown-6 (18c6), features a flexible six-oxygen cyclic backbone that is well-known for its selective cation binding. This study employs infrared spectroscopy and quantum mechanical calculations to elucidate the structure of the gas-phase complexes formed by the 18c6 ether with the alkali metal cations. It is shown that symmetric and chiral arrangements play a dominant role in the conformational landscape of the 18c6-alkali system. Most stable 18c6-M(+) conformers are found to have symmetries C(3v) and C(2) for Cs(+), D(3d) for K(+), C(1) and D(3d) for Na(+), and D(2) for Li(+). Remarkably, whereas the bare 18c6 ether is achiral, chirality emerges in the C(2) and D(2) 18c6-M(+) conformations, both of which involve pairs of stable atropoisomers capable of acting as enantiomeric selective substrates.

    The Spanish use of words like human, humane, humanitarian, humanist and humanistic (humano, humanista, humanístico y humanitario) as synonyms has created some confusion. Human (humano) is related with man's nature, its goodness and evil; humane and humanitarian (humanitario) with kindness and benevolence; humanistic (humanístico) with the cultural and artistic movement that began in renaissance and with anthropocentric philosophy, while humanist (humanista) is identified with the fields of learning (humanities) including the arts, history, literature, and philosophy, excluding the sciences. Medicine and physicians must have all these attributes.

  3. Progress and gaps in reproductive health services in three humanitarian settings: mixed-methods case studies

    PubMed Central

    2015-01-01

    Background Reproductive health (RH) care is an essential component of humanitarian response. Women and girls living in humanitarian settings often face high maternal mortality and are vulnerable to unwanted pregnancy, unsafe abortion, and sexual violence. This study explored the availability and quality of, and access barriers to RH services in three humanitarian settings in Burkina Faso, Democratic Republic of the Congo (DRC), and South Sudan. Methods Data collection was conducted between July and October 2013. In total, 63 purposively selected health facilities were assessed: 28 in Burkina Faso, 25 in DRC, and nine in South Sudan, and 42 providers completed a questionnaire to assess RH knowledge and attitudes. Thirty-four focus group discussions were conducted with 29 members of the host communities and 273 displaced married and unmarried women and men to understand access barriers. Results All facilities reported providing some RH services in the prior three months. Five health facilities in Burkina Faso, six in DRC, and none in South Sudan met the criteria as a family planning service delivery point. Two health facilities in Burkina Faso, one in DRC, and two in South Sudan met the criteria as an emergency obstetric and newborn care service delivery point. Across settings, three facilities in DRC adequately provided selected elements of clinical management of rape. Safe abortion was unavailable. Many providers lacked essential knowledge and skills. Focus groups revealed limited knowledge of available RH services and socio-cultural barriers to accessing them, although participants reported a remarkable increase in use of facility-based delivery services. Conclusion Although RH services are being provided, the availability of good quality RH services was inconsistent across settings. Commodity management and security must be prioritized to ensure consistent availability of essential supplies. It is critical to improve the attitudes, managerial and technical

    Although considerable achievements in the global reduction of hunger and poverty have been made, progress in Africa so far has been very limited. At present, a third of the African population faces widespread hunger and chronic malnutrition and is exposed to a constant threat of acute food crisis and famine. The most affected are rural households whose livelihood is heavily dependent on traditional rainfed agriculture. Rainfall plays a major role in determining agricultural production and hence the economic and social well being of rural communities. The rainfall pattern in sub-Saharan Africa is influenced by large-scale intra-seasonal and inter-annual climate variability including occasional El Niño events in the tropical Pacific resulting in frequent extreme weather event such as droughts and floods that reduce agricultural outputs resulting in severe food shortages. Households and communities facing acute food shortages are forced to adopt coping strategies to meet the immediate food requirements of their families. These extreme responses may have adverse long-term, impacts on households' ability to have sustainable access to food as well as the environment. The HIV/AIDS crisis has also had adverse impacts on food production activities on the continent. In the absence of safety nets and appropriate financial support mechanisms, humanitarian aid is required to enable households effectively cope with emergencies and manage their limited resources more efficiently. Timely and appropriate humanitarian aid will provide households with opportunities to engage in productive and sustainable livelihood strategies. Investments in poverty reduction efforts would have better impact if complemented with timely and predictable response mechanisms that would ensure the protection of livelihoods during crisis periods whether weather or conflict-related. With an improved understanding of climate variability including El Niño, the implications of weather patterns for the food

    2005-12-19

    This report provides an estimate of the leak rate from the emergency pump well in L-basin that is to be expected during an off-normal event. This estimate is based on expected shrinkage of the engineered grout (i.e., controlled low strength material) used to fill the emergency pump well and the header pipes that provide the dominant leak path from the basin to the lower levels of the L-Area Complex. The estimate will be used to provide input into the operating safety basis to ensure that the water level in the basin will remain above a certain minimum level. The minimum basin water level is specified to ensure adequate shielding for personnel and maintain the ''as low as reasonably achievable'' concept of radiological exposure. The need for the leak rate estimation is the existence of a gap between the fill material and the header pipes, which penetrate the basin wall and would be the primary leak path in the event of a breach in those pipes. The gap between the pipe and fill material was estimated based on a full scale demonstration pour that was performed and examined. Leak tests were performed on full scale pipes as a part of this examination. Leak rates were measured to be on the order of 0.01 gallons/minute for completely filled pipe (vertically positioned) and 0.25 gallons/minute for partially filled pipe (horizontally positioned). This measurement was for water at 16 feet head pressure and with minimal corrosion or biofilm present. The effect of the grout fill on the inside surface biofilm of the pipes is the subject of a previous memorandum.

    Emergency situations in road complex are road traffic accidents (RA) with severe consequences. These are incidents connected with the death and injury of large number of people. The most common reasons for this are the collision of three or more cars, the collision of buses with trains at railroad crossings, the fall of the buses in the mountain gorge, and other similar cases. Is it possible to predict such events? How to build a preventive protection against such emergencies? We have to understand that emergencies in a road complex are qualitative expression of the quantitative processes that characterize the general state of road safety in the region. In this regard, at the level of state monitoring of emergency situations it is important to understand in general - in which region the situation is more complicated and in which is more favorable. This knowledge helps to more efficiently reallocate resources intended to solve the problems of road safety provision. The consequence of this is improvement of the quality of preventive protection from the emergencies in the road complex. The article presents quantitative values of severity of accidents in the Russian Federation regions and the Pareto chart distribution of cumulates of the accident severity for the Russian Federation. On the basis of the complex assessment of the spatial non-uniformity of the accident severity results it offers two important recommendations, implementation of which will alleviate the issue of formation of emergency situations in the road of the Russian Federation on the basis of the complex assessment of the spatial nonuniformity of the accident severity results.

    In this article we shall focus on learning-teaching trajectories ='successful' as well as 'unsuccessful' ones - as emergent and dynamic phenomena resulting from the interactions in the entire educational context, in particular the interaction between students and teachers viewed as processes of intertwining self-, other- and co-regulation. The article provides a review of the educational research literature on action regulation in learning and teaching, and interprets this literature in light of the theory of complex dynamic systems. Based on this reinterpretation of the literature, two dynamic models are proposed, one focusing on the short-term dynamics of learning-teaching interactions as they take place in classrooms, the other focusing on the long-term dynamics of interactions in a network of variables encompassing concerns, evaluations, actions and action effects (such as learning) students and teachers. The aim of presenting these models is to demonstrate, first, the possibility of transforming existing educational theory into dynamic models and, second, to provide some suggestions as to how such models can be used to further educational theory and practice.

    CK2 is a Ser/Thr protein kinase that is highly conserved amongst all eukaryotes. It is a well-known oncogenic kinase that regulates vital cell autonomous functions and animal development. Genetic studies in the fruit fly Drosophila are providing unique insights into the roles of CK2 in cell signaling, embryogenesis, organogenesis, neurogenesis, and the circadian clock, and are revealing hitherto unknown complexities in CK2 functions and regulation. Here, we review Drosophila CK2 with respect to its structure, subunit diversity, potential mechanisms of regulation, developmental abnormalities linked to mutations in the gene encoding CK2 subunits, and emerging roles in multiple aspects of eye development. We examine the Drosophila CK2 “interaction map” and the eye-specific “transcriptome” databases, which raise the prospect that this protein kinase has many additional targets in the developing eye. We discuss the possibility that CK2 functions during early retinal neurogenesis in Drosophila and mammals bear greater similarity than has been recognized, and that this conservation may extend to other developmental programs. Together, these studies underscore the immense power of the Drosophila model organism to provide new insights and avenues to further investigate developmentally relevant targets of this protein kinase.

    Recent advances in the neuromorphic operation of atomic switches as individual synapse-like devices demonstrate the ability to process information with both short-term and long-term memorization in a single two terminal junction. Here it is shown that atomic switches can be self-assembled within a highly interconnected network of silver nanowires similar in structure to Turing’s “B-Type unorganized machine”, originally proposed as a randomly connected network of NAND logic gates. In these experimental embodiments,complex networks of coupled atomic switches exhibit emergent criticality similar in nature to previously reported electrical activity of biological brains and neuron assemblies. Rapid fluctuations in electrical conductance display metastability and power law scaling of temporal correlation lengths that are attributed to dynamic reorganization of the interconnected electro-ionic network resulting from induced non-equilibrium thermodynamic instabilities. These collective properties indicate a potential utility for realtime,multi-input processing of distributed sensory data through reservoir computation. We propose these highly coupled, nonlinear electronic networks as an implementable hardware-based platform toward the creation of physically intelligent machines.

  14. Holonic Rationale and Bio-inspiration on Design of Complex Emergent and Evolvable Systems

    NASA Astrophysics Data System (ADS)

    Leitao, Paulo

    Traditional centralized and rigid control structures are becoming inflexible to face the requirements of reconfigurability, responsiveness and robustness, imposed by customer demands in the current global economy. The Holonic Manufacturing Systems (HMS) paradigm, which was pointed out as a suitable solution to face these requirements, translates the concepts inherited from social organizations and biology to the manufacturing world. It offers an alternative way of designing adaptive systems where the traditional centralized control is replaced by decentralization over distributed and autonomous entities organized in hierarchical structures formed by intermediate stable forms. In spite of its enormous potential, methods regarding the self-adaptation and self-organization of complex systems are still missing. This paper discusses how the insights from biology in connection with new fields of computer science can be useful to enhance the holonic design aiming to achieve more self-adaptive and evolvable systems. Special attention is devoted to the discussion of emergent behavior and self-organization concepts, and the way they can be combined with the holonic rationale.

    Citrus leprosis complex is an emerging disease in the Americas, associated with two unrelated taxa of viruses distributed in South, Central, and North America. The cytoplasmic viruses are Citrus leprosis virus C (CiLV-C), Citrus leprosis virus C2 (CiLV-C2), and Hibiscus green spot virus 2, and the nuclear viruses are Citrus leprosis virus N (CiLV-N) and Citrus necrotic spot virus. These viruses cause local lesion infections in all known hosts, with no natural systemic host identified to date. All leprosis viruses were believed to be transmitted by one species of mite, Brevipalpus phoenicis. However, mites collected from CiLV-C and CiLV-N infected citrus groves in Mexico were identified as B. yothersi and B. californicus sensu lato, respectively, and only B. yothersi was detected from CiLV-C2 and CiLV-N mixed infections in the Orinoco regions of Colombia. Phylogenetic analysis of the helicase, RNA-dependent RNA polymerase 2 domains and p24 gene amino acid sequences of cytoplasmic leprosis viruses showed a close relationship with recently deposited mosquito-borne negevirus sequences. Here, we present evidence that both cytoplasmic and nuclear viruses seem to replicate in viruliferous Brevipalpus species. The possible replication in the mite vector and the close relationship with mosquito borne negeviruses are consistent with the concept that members of the genus Cilevirus and Higrevirus originated in mites and citrus may play the role of mite virus vector.

    These proceedings present the Invited Lectures and Contributed Papers of the Fourth International Workshop on Decoherence, Information, Complexity and Entropy - DICE 2008, held at Castello Pasquini, Castiglioncello (Tuscany), 22-26 September 2008. We deliver these proceedings as a means to document to the interested public, to the wider scientific community, and to the participants themselves the stimulating exchange of ideas at this conference. The steadily growing number of participants, among them acclaimed scientists in their respective fields, show its increasing attraction and a fruitful concept, based on bringing leading researchers together and in contact with a mix of advanced students and scholars. Thus, this series of meetings successfully continued from the beginning with DICE 2002, (Decoherence and Entropy in Complex Systems ed H-T Elze Lecture Notes in Physics 633 (Berlin: Springer, 2004)) followed by DICE 2004 (Proceedings of the Second International Workshop on Decoherence, Information, Complexity and Entropy - DICE 2004 ed H-T Elze Braz. Journ. Phys. 35, 2A & 2B (2005) pp 205-529 free access at: www.sbfisica.org.br/bjp) and by DICE 2006, (Proceedings of the Third International Workshop on Decoherence, Information, Complexity and Entropy - DICE 2006 eds H-T Elze, L Diósi and G Vitiello Journal of Physics: Conference Series 67 (2007); free access at: http://www.iop.org/EJ/toc/1742-6596/67/1) uniting about one hundred participants from more than twenty different countries worldwide this time. It has been a great honour and inspiration for all of us to have Professor Sir Roger Penrose from the Mathematical Institute at the University of Oxford with us, who presented the lecture ``Black holes, quantum theory and cosmology'' (included in this volume). Discussions under the wider theme ``From Quantum Mechanics through Complexity to Spacetime: the role of emergent dynamical structures'' took place in the very pleasant and inspiring atmosphere of Castello

    The earthquake that occurred in Haiti on 12 January 2010 resulted in massive infrastructure damage, and created one of the largest single-day loss of life events in modern history. Despite the tragic mortality rates, many people with catastrophic injuries including spinal cord injuries and amputations survived due to swift emergency responses by local and international non-governmental organisations (NGOs). The outcome however is that Haiti now has a considerable cohort of people who live with important disabilities. In this 'perspectives in rehabilitation' we share our experiences of working in post-earthquake Haiti, and highlight that this event has raised awareness of the critical importance of providing rehabilitation services during and after a humanitarian crisis of this magnitude.

  19. Legal issues of humanitarian assistance after the 2007 earthquake in Pisco, Peru.

    The earthquake that struck the central coast of Peru on 15 August 2007 was a disaster that mobilized international humanitarian assistance to address the needs of the affected people in the regions of Huancavelica, Ica, and Lima. It also was an opportunity to prove the effectiveness of regulations and procedures to facilitate the entry and distribution of donations and medical goods during a major emergency. In the first month after the earthquake, the national government approved new regulations that aimed to reduce waiting time while reducing the number of requisites required by customs. More than 5,500 tons of international donations arrived in Peru in a short period of time. Many donated medicines arrived unsorted, without an international non-proprietary (generic) name on the label, and some medicines did not have any relationship with the diseases that would appear in the aftermath of the event.

    Language serves as a primary tool for structuring identity and loss of language represents the loss of that identity. This study utilizes a social network analysis of Ktunaxa speech community activities for evidence of internally generated revitalization efforts. These behaviors include instances of self-organized emergence. Such emergent behavior…

  1. Stabilisation and humanitarian access in a collapsed state: the Somali case.

    PubMed

    Menkhaus, Ken

    2010-10-01

    Somalia today is the site of three major threats: the world's worst humanitarian crisis; the longest-running instance of complete state collapse; and a robust jihadist movement with links to Al-Qa'ida. External state-building, counter-terrorism and humanitarian policies responding to these threats have worked at cross-purposes. State-building efforts that insist humanitarian relief be channelled through the nascent state in order to build its legitimacy and capacity undermine humanitarian neutrality when the state is a party to a civil war. Counter-terrorism policies that seek to ensure that no aid benefits terrorist groups have the net effect of criminalising relief operations in countries where poor security precludes effective accountability. This paper argues that tensions between stabilisation and humanitarian goals in contemporary Somalia reflect a long history of politicisation of humanitarian operations in the country.

  2. Invitation withdrawn: humanitarian action, United Nations peacekeeping, and state sovereignty in Chad.

    PubMed

    Karlsrud, John; Felix da Costa, Diana

    2013-10-01

    This paper looks at the three-way relationship between the Government of Chad, humanitarians, and the United Nations Mission in the Central African Republic and Chad (MINURCAT) from 2004 until June 2011. Chad was never comfortable with the international presence of either humanitarians or peacekeepers and asserted its sovereignty increasingly during this period. MINURCAT was deployed in 2008 to protect humanitarian workers and to facilitate the provision of humanitarian assistance in eastern Chad. This association between the UN mission and humanitarian agencies contributed to making the latter the target of repressive practices by the government, such as the imposition of armed escorts. Facing a steep learning curve, Chad and its state officials gradually appropriated the discourse of the humanitarian and international community and ultimately, in 2010, requested the departure of MINURCAT, claiming that they could meet the protection needs of vulnerable populations in eastern Chad on their own.

  3. Shelter strategies, humanitarian praxis and critical urban theory in post-crisis reconstruction.

    PubMed

    Fan, Lilianne

    2012-07-01

    The paper seeks to link contemporary thinking on urban shelter in the humanitarian sector to debates in the field of 'critical urban theory'. It argues that current humanitarian thinking on urban shelter shares many common concerns with critical urban theory, but that these concerns are rarely translated effectively into humanitarian practice. It attributes this disconnect not only to weaknesses in implementation capacity, but also to the need to reorient humanitarian action to address more definitively questions of power and justice. Humanitarian actors need to step back from product-delivery approaches and find ways of integrating into their analytical, planning, implementation and monitoring tools questions about access, exclusion and the historically specific ways in which these aspects converge in particular urban spaces. By doing so, the humanitarian community would benefit from a more explicit, systematic and sustained engagement with the catalytic theoretical resources that critical urban theory has to offer.

    In April 1999, during the crisis in Kosovo, the Israeli government launched a medical, field hospital in order to provide humanitarian aid to the Albanian refugees that fled from their homes in Kosovo. This facility was set up by the Medical Corps of the Israeli Defense Forces, in a refugee camp located in Northern Macedonia. During the 16 days during which the hospital functioned, the medical staff treated 1,560 patients and hospitalized >100. The field hospital served as a referral center for all of the other primary clinics that were hastily erected in the camp and its surroundings. This communication elaborates on the various aspects of the humanitarian medical aid that were provided by this medical facility and the conclusions that learned from such a mission.

    PubMed Central

    Legros, Dominique; Formenty, Pierre; Connolly, Maire A.

    2007-01-01

    Detection and control of emerging infectious diseases in conflict situations are major challenges due to multiple risk factors known to enhance emergence and transmission of infectious diseases. These include inadequate surveillance and response systems, destroyed infrastructure, collapsed health systems and disruption of disease control programs, and infection control practices even more inadequate than those in resource-poor settings, as well as ongoing insecurity and poor coordination among humanitarian agencies. This article outlines factors that potentiate emergence and transmission of infectious diseases in conflict situations and highlights several priority actions for their containment and control.

    Northern ecosystems are currently experiencing unprecedented ecological change, largely driven by a rapidly changing climate. Pathogen range expansion, and emergence and altered patterns of infectious disease, are increasingly reported in wildlife at high latitudes. Understanding the causes and consequences of shifting pathogen diversity and host-pathogen interactions in these ecosystems is important for wildlife conservation, and for indigenous populations that depend on wildlife. Among the key questions are whether disease events are associated with endemic or recently introduced pathogens, and whether emerging strains are spreading throughout the region. In this study, we used a phylogenomic approach to address these questions of pathogen endemicity and spread for Erysipelothrix rhusiopathiae, an opportunistic multi-host bacterial pathogen associated with recent mortalities in arctic and boreal ungulate populations in North America. We isolated E. rhusiopathiae from carcasses associated with large-scale die-offs of muskoxen in the Canadian Arctic Archipelago, and from contemporaneous mortality events and/or population declines among muskoxen in northwestern Alaska and caribou and moose in western Canada. Bacterial genomic diversity differed markedly among these locations; minimal divergence was present among isolates from muskoxen in the Canadian Arctic, while in caribou and moose populations, strains from highly divergent clades were isolated from the same location, or even from within a single carcass. These results indicate that mortalities among northern ungulates are not associated with a single emerging strain of E. rhusiopathiae, and that alternate hypotheses need to be explored. Our study illustrates the value and limitations of bacterial genomic data for discriminating between ecological hypotheses of disease emergence, and highlights the importance of studying emerging pathogens within the broader context of environmental and host factors.

  17. Corruption in emergency procurement.

    PubMed

    Schultz, Jessica; Søreide, Tina

    2008-12-01

    Corruption in emergency procurement reduces the resources available for life-saving operations, lowers the quality of products and services provided, and diverts aid from those who need it most.(1) It also negatively influences public support for humanitarian relief, both in the affected country and abroad. This paper aims to unpack and analyse the following question in order to mitigate risk: how and where does corruption typically occur, and what can be done? Suggested strategies reflect a multi-layered approach that stresses internal agency control mechanisms, conflict-sensitive management, and the need for common systems among operators.

  18. Emergence of complex and spinor wave functions in scale relativity. II. Lorentz invariance and bi-spinors

    Owing to the non-differentiable nature of the theory of Scale Relativity, the emergence of complex wave functions, then of spinors and bi-spinors occurs naturally in its framework. The wave function is here a manifestation of the velocity field of geodesics of a continuous and non-differentiable (therefore fractal) space-time. In a first paper (Paper I), we have presented the general argument which leads to this result using an elaborate and more detailed derivation than previously displayed. We have therefore been able to show how the complex wave function emerges naturally from the doubling of the velocity field and to revisit the derivation of the non-relativistic Schrödinger equation of motion. In the present paper (Paper II), we deal with relativistic motion and detail the natural emergence of the bi-spinors from such first principles of the theory. Moreover, while Lorentz invariance has been up to now inferred from mathematical results obtained in stochastic mechanics, we display here a new and detailed derivation of the way one can obtain a Lorentz invariant expression for the expectation value of the product of two independent fractal fluctuation fields in the sole framework of the theory of Scale Relativity. These new results allow us to enhance the robustness of our derivation of the two main equations of motion of relativistic quantum mechanics (the Klein-Gordon and Dirac equations) which we revisit here at length.

  20. Structural Vulnerability Among Migrating Women and Children Fleeing Central America and Mexico: The Public Health Impact of "Humanitarian Parole".

    PubMed

    Valdez, Elizabeth Salerno; Valdez, Luis A; Sabo, Samantha

    2015-01-01

    Since October 2013, US Customs and Border Patrol has apprehended 15,979 families on the Southwest Border of the US. Daily, migrating women and children from Mexico and Central America that qualify for humanitarian parole are released from immigration detention to a humanitarian aid organization in Southern Arizona. After several days in detention facilities, these families arrive tired, hungry, dehydrated, and with minimal direction regarding their final destination, and adherence to the parameters of their parole. Project helping hands (PHHs) utilizes a network of volunteers to provide the women and children with food, water, clothing, hygiene products, hospitality, and legal orientation. The aim of this assessment was to document the experiences of families granted humanitarian parole through the lens of structural vulnerability. Here, we apply qualitative methods to elicit PHH lead volunteer perspectives regarding the migration experience of migrating families. Using inductive analysis, we found six major themes emerged from the qualitative data: reasons for leaving, experience on the journey, dehumanization in detention, family separation, vulnerability, and resiliency. These findings elucidate the different physical and psychological distresses that migrating families from Mexico and Central America experience before, during and after their arrival at the US-Mexico border. We posit that these distresses are a result of, or exacerbated by, structural vulnerability. Structural vulnerability has life-long health implications for a sub-population of young mothers and their children. The number of migrating families who have experienced traumatic events before and during their migration experience continues to expand and thus warrants consideration of mental health surveillance and intervention efforts for these families. More public health research is needed to better understand and combat the health challenges of this growing population.

  9. Emergency ground-water supplies in the Seattle-Tacoma urban complex and adjacent areas, Washington

    USGS Publications Warehouse

    Foxworthy, B.L.

    1972-01-01

    Urban areas that are supplied from surface-water sources are especially vulnerable to major disruption of their water supplies. Such disruption could result from natural disasters such as earthquakes, floods, or landslides or from such other causes as dam failures fallout of radioactive material or other toxic substance from the atmosphere or other toxic substances from the atmosphere or direct introduction (either accidental or deliberate) of any substance that would render the water unfit for use. Prolonged disruption of public water supplies not only causes personal hardships but also endangers health and safety unless suitable alternative emergency supplies can be provided. The degree of hardship and danger generally increases in direct relation to the population density. Ground water because it occurs beneath protective soil and rock materials is less subject to sudden major contamination than are surface-water bodies. For this reason and also because of its widespread availability in the Puget Sound region ground water is especially desireable as a sources of emergency supplies for drinking or other uses requiring water of good quality. In much of the area existing wells would be suitable as safe sources of emergency supplies.

  10. Social dimensions of science-humanitarian collaboration: lessons from Padang, Sumatra, Indonesia.

    Shannon, Rachel; Hope, Max; McCloskey, John; Crowley, Dominic; Crichton, Peter

    2014-07-01

    This paper contains a critical exploration of the social dimensions of the science-humanitarian relationship. Drawing on literature on the social role of science and on the social dimensions of humanitarian practice, it analyses a science-humanitarian partnership for disaster risk reduction (DRR) in Padang, Sumatra, Indonesia, an area threatened by tsunamigenic earthquakes. The paper draws on findings from case study research that was conducted between 2010 and 2011. The case study illustrates the social processes that enabled and hindered collaboration between the two spheres, including the informal partnership of local people and scientists that led to the co-production of earthquake and tsunami DRR and limited organisational capacity and support in relation to knowledge exchange. The paper reflects on the implications of these findings for science-humanitarian partnering in general, and it assesses the value of using a social dimensions approach to understand scientific and humanitarian dialogue.

  11. Internally displaced women as knowledge producers and users in humanitarian action: the view from Colombia.

    PubMed

    Sandvik, Kristin Bergtora; Lemaitre, Julieta

    2013-07-01

    The literature on evidence-based action in humanitarian crises commonly focuses on how inter-and non-governmental organisations can produce better knowledge and how this can be translated into improved programming. Yet, there is little recorded experience of, or concern about, how the beneficiaries of humanitarian relief can produce and use knowledge of their predicament. This paper is based on a case study of how the Liga de Mujeres Desplazadas, an internally displaced women's organisation in northern Colombia, employs proactively research-generated data to advance its own agenda in its interactions with donor bodies and the government. The paper finds that beneficiaries of humanitarian aid can, and do, use participatory research to advance their own ends in the legal and political spaces created around humanitarian crisis. However, their agency is limited by poverty, violence, and local balances of power. The paper concludes that beneficiaries' priorities in the production of data about humanitarian crises warrant further study.

  12. Humanitarian presence and urban development: new opportunities and contrasts in Goma, DRC.

    This paper examines the impact of the presence of international humanitarian organisations on local urban transformation processes in the city of Goma, Democratic Republic of the Congo (DRC). Rather than evaluating the direct effects of humanitarian interventions and strategies, it focuses on the indirect but profound effects of the presence of this 'humanitarian sector'. It argues that the international humanitarian presence became a significant factor in the recent shaping and reshaping of the city's profile and has reinforced competition over the urban political and socioeconomic space. The paper evaluates the direct and indirect impact of the international humanitarian presence on the local urban economy and the larger political economy of war in eastern DRC. It analyses how this presence has reinforced processes of spatial reconfiguration, how it has influenced urban planning, and how it has affected dynamics of gentrification and marginalisation on the urban spatial level.

  13. Save the Children, the humanitarian project, and the politics of solidarity: reviving Dorothy Buxton's vision.

    This paper reflects on the foundational years of Save the Children, one of the oldest and largest Western humanitarian agencies and a mainstay of the humanitarian project. In doing so, it considers how and why, at an early stage, the organisation depoliticised its activities, centring its narrative on the innocent, pre-political child-the image of unsullied humanity. In addition, it seeks to recover the internationalist vision of Save the Children's 'forgotten founder', Dorothy Buxton. Save the Children's turn to non-politics is indicative of the broader depoliticisation of Western humanitarian action. Given the intensely contested spaces in which Western humanitarian non-governmental organisations (NGOs) operate, these entities cannot escape politics. This paper argues that Buxton's efforts to build an international solidarity network through humanitarian action after the end of the First World War in 1918 provide an instructive basis on which these NGOs can pursue a politics of solidarity in the present day.

  14. Emergent complexity matching in interpersonal coordination: Local dynamics and global variability.

    Rhythmic coordination with stimuli and other people's movements containing variable or unpredictable fluctuations might involve distinct processes: detecting the fluctuation structure and tuning to or matching the structure's temporal complexity. This framework predicts that global tuning and local parameter adjustments (e.g., position, velocity or phase) can operate independently during coordination (Marmelat & Delignières, 2012). Alternatively, we propose that complexity matching is a result of local phase adjustments during coordination (Delignières & Marmelat, 2014; Torre, Varlet, & Marmelat, 2013). The current study examined this relationship in a rhythmic interpersonal coordination task. Dyads coordinated swinging pendulums that differed in their uncoupled frequencies (detuning). We predicted that frequency detuning would require increased local corrections to maintain the intended phase pattern (in phase). This was expected to yield a relative phase shift accompanied by a change in period complexity and matching. Experimental data and numerical modeling of the pendulum dynamics confirmed our predictions. Increased relative phase shifts occurred simultaneously with increased dissociation between individuals' movement period complexity. This provided evidence that global complexity matching is intricately linked to local movement adjustments and is not a distinct coordination mechanism. These findings are considered with respect to dynamical and computational approaches to interpersonal coordination.

  15. Ruthenium Complexes: An Emerging Ground to the Development of Metallopharmaceuticals for Cancer Therapy.

    2016-01-01

    GLOBOCAN 2012 estimates 14.1 million new cancer cases and 8.2 million cancer-related deaths worldwide. Cancer is rapidly becoming a major public health concern in India as well, with the number of new cancer cases anticipated to double within the next 20 years. The percentage of currently approved metallodrugs is very low, in contrast to the majority of drugs available as organic compounds. The search for alternative drugs to cisplatin, carboplatin and other derivatives is highly needed due to their severe side effects including nephrotoxicity and neurotoxicity. Ruthenium, among other transition metal complexes appears to be a possible candidate for cancer therapy in the near future. The most significant rationale is ruthenium's octahedral chemistry and greater propensity to undergo redox reactions. The hypoxic environment of tumors favors the reduction of inert ruthenium (III) to active ruthenium (II) which opens new prospects for the development of novel prodrugs. Although studies suggest that ruthenium complexes penetrate well within the tumor cells and bind effectively to DNA, its binding to proteins is not very well explained. Ruthenium complexes are presently receiving great attention in the fields of biological, pharmaceutical and medicinal chemistry as anticancer agents. This review poses a comprehensive overview of the studies on competent anticancer ruthenium complexes and the role of these metal complexes in relation to their anticancer properties as well as those under clinical trials.

  16. A Stroop effect emerges in the processing of complex Chinese characters that contain a color-related radical.

    2015-03-01

    Three experiments examined whether a Stroop effect emerges in the processing of complex Chinese characters that contain a color-related radical. In Experiment 1, a Stroop effect occurred when participants responded to the black or white color of the simple characters [Chinese character: see text] (black) and [Chinese character: see text] (white) by making a left or right keypress. For Experiment 2, in which the stimuli were complex characters whose meanings were unrelated to color but that contained [Chinese character: see text] or [Chinese character: see text] as a radical, a Stroop effect also occurred, although it was smaller than in Experiment 1. Furthermore, this Stroop effect as a function of radical meaning was shown again in Experiment 3 for low-frequency complex characters but not high-frequency ones. These results suggest that the semantic representations of the complex characters’ color-related radicals are accessed in the context of a Stroop color word task, especially for low-frequency characters. Reduction of the Stroop effect in complex characters composed of one radical with color meaning and one without is similar to dilution of the Stroop effect that occurs when a color word is accompanied by a neutral word. Possible implications of the results for accounts of Stroop dilution are discussed.

    We examine how the catalytic domain of a glycoside hydrolase family 7 endoglucanase catalytic domain (Cel7B CD) facilitates complexation of cellulose chains from a crystal surface. With direct relevance to the science of biofuel production, this problem also represents a model system of biopolymer processing by proteins in Nature. Interactions of Cel7B CD with a cellulose microfibril along different paths of complexation are characterized by mapping the atomistic fluctuations recorded in free-energy simulations onto the parameters of a coarse-grain model. The resulting patterns of protein-biopolymer couplings also uncover the sequence signatures of the enzyme in peeling off glucan chains from the microfibril substrate. We show that the semiopen active site of Cel7B CD exhibits similar barriers and free energies of complexation over two distinct routes; namely, scooping of a chain into the active-site cleft and threading from the chain end into the channel. On the other hand, the complexation energetics strongly depends on the surface packing of the targeted chain and the resulting interaction sites with the enzyme. A revealed principle is that Cel7B CD facilitates cellulose deconstruction via adaptive coupling to the emergent substrate. The flexible, peripheral segments of the protein outside of the active-site cleft are able to accommodate the varying features of cellulose along the simulated paths of complexation. The general strategy of linking physics-based molecular interactions to protein sequence could also be helpful in elucidating how other protein machines process biopolymers.

    2014-09-01

    The definition of complexity through Statistical Complexity Measures (SCM) has recently seen major improvements. Mostly, the effort is concentrated in measures on time series. We propose a SCM definition for spatial dynamical systems. Our definition is in line with the trend to combine entropy with measures of structure (such as disequilibrium). We study the behaviour of our definition against the vectorial noise model of Collective Motion. From a global perspective, we show how our SCM is minimal at both the microscale and macroscale, while it reaches a maximum at the ranges that define the mesoscale in this model. From a local perspective, the SCM is minimum both in highly ordered and disordered areas, while it reaches a maximum at the edges between such areas. These characteristics suggest this is a good candidate for detecting the mesoscale of arbitrary dynamical systems as well as regions where the complexity is maximal in such systems.

  19. Computational and Experimental Evidence of Emergent Equilibrium Isotope Effects in Anion Receptor Complexes

    PubMed Central

    2017-01-01

    The measurement of a deuterium equilibrium isotope effect (EIE) for the aryl CH···Cl– interaction of anion receptor 1H/1D is reported. Computations corroborate the results of solution measurements for a small, normal EIE in the full complex (KaH/KaD = 1.019 ± 0.010). Interestingly, isotope effects involving fragments of the anion receptor (urea, aryl ring, etc.) are predicted to produce an inverse effect. This points to an unusual and subtle structural organization effect of the anion receptor complex that changes the nature of the combined interactions to a normal isotope effect. The reversal of EIE values suggests that overall architecture of the anion receptor can dramatically impact the nature of bonding in these complexes. PMID:28282134

    Mental health in low- and middle income countries has received increasing attention. This attention has shifted focus, roughly moving from demonstrating the burden of mental health problems, to establishing an evidence base for interventions, to thinking about care delivery frameworks. This paper reviews these trends specifically for humanitarian settings and discusses lessons learned. Notably, that mental health assessments need to go beyond measuring the impact of traumatic events on circumscribed psychiatric disorders; that evidence for effectiveness of interventions is still too weak and its focus too limited; and that development of service delivery in the context of instable community and health systems should be an area of key priority.

    A new approach to the assemblage of complex networks displaying the scale-free architecture is proposed. While the growth and the preferential attachment of incoming nodes assure an emergence of such networks according to the Barabási-Albert model, it is argued here that the preferential linking condition needs not to be a principal rule. To assert this statement a simple computer model based on random walks on fractal lattices is introduced. It is shown that the model successfully reproduces the degree distributions, the ultra-small-worldness and the high clustering arising from the topology of scale-free networks.

  2. Tracking humanitarian funding for reproductive health: a systematic analysis of health and protection proposals from 2002-2013

    2015-01-01

    Background The Inter-agency Working Group on Reproductive Health in Crises conducted a ten-year global evaluation of reproductive health in humanitarian settings. This paper examines proposals for reproductive health activities under humanitarian health and protection funding mechanisms for 2002-2013, and the level at which these reproductive health proposals were funded. Methods The study used English and French health and protection proposal data for 2002-2013, extracted from the Financial Tracking Service (FTS) database managed by the United Nations Office for the Coordination of Humanitarian Affairs. Every project was reviewed for relevance against pre-determined reproductive health definitions for 2002-2008. An in-depth analysis was additionally conducted for 2009-2013 through systematically reviewing proposals via a key word search and subsequently classifying them under designated reproductive health categories. Among the relevant reproductive health proposals, counts and proportions were calculated in Excel based on their reproductive health components, primarily by year. Contributions, requests, and unfunded requests were calculated based on the data provided by FTS. Results Among the 11,347 health and protection proposals issued from 345 emergencies between 2002 and 2013, 3,912 were relevant to reproductive health (34.5%). The number of proposals containing reproductive health activities increased by an average of 21.9% per year, while the proportion of health and protection sector appeals containing reproductive health activities increased by an average of 10.1% per year. The total funding request over the 12 years amounted to $4.720 billion USD, of which $2.031 billion USD was received. Among reproductive health components for 2009-2013 proposals, maternal newborn health comprised the largest proportion (56.4%), followed by reproductive health-related gender-based violence (45.9%), HIV/sexually transmitted infections (37.5%), general reproductive health

    The importance of 'small-worlds', fractals and complex networks to medicine are discussed. The interrelationship between the concepts is highlighted. 'Small-worlds'--where large populations are linked at the level of the individual have considerable importance for understanding disease transmission. Complex networks where linkages are based on the concept 'the rich get richer' are fundamental in the medical sciences--from enzymatic interactions at the subcellular level to social interactions such as sexual liaisons. Mathematically 'the rich get richer' can be modeled as a power law. Fractal architecture and time sequences can also be modeled by power laws and are ubiquitous in nature with many important examples in medicine. The potential of fractal life support--the return of physiological time sequences to devices such as mechanical ventilators and cardiopulmonary bypass pumps--is presented in the context of a failing complex network. Experimental work suggests that using fractal time sequences improves support of failing organs. Medicine, as a science has much to gain by embracing the interrelated concepts of 'small-worlds', fractals and complex networks. By so doing, medicine will move from the historical reductionist approach toward a more holistic one.

    Health-care waste management requires technical, financial and human resources, and it is a challenge for low- and middle income countries, while it is often neglected in protracted crisis or emergency situations. Indeed, when health, safety, security or wellbeing of a community is threatened, solid waste management usually receives limited attention. Using the Gaza Strip as the case study region, this manuscript reports on health-care waste management within the context of a humanitarian crisis. The study employed a range of methods including content analyses of policies and legislation, audits of waste arisings, field visits, stakeholder interviews and evaluation of treatment systems. The study estimated a production from clinics and hospitals of 683kg/day of hazardous waste in the Gaza Strip, while the total health-care waste production was 3357 kg/day. A number of challenges was identified including lack of clear definitions and regulations, limited accurate data on which to base decisions and strategies and poor coordination amongst key stakeholders. Hazardous and non-hazardous waste was partially segregated and treatment facilities hardly used, and 75% of the hazardous waste was left untreated. Recommendations for mitigating these challenges posed to patients, staff and the community in general are suggested. The outputs are particularly useful to support decision makers, and re-organize the system according to reliable data and sound assumptions. The methodology can be replicated in other humanitarian settings, also to other waste flows, and other sectors of environmental sanitation.

    2013-11-01

    One of the main results of scale relativity as regards the foundation of quantum mechanics is its explanation of the origin of the complex nature of the wave function. The scale relativity theory introduces an explicit dependence of physical quantities on scale variables, founding itself on the theorem according to which a continuous and non-differentiable space-time is fractal (i.e., scale-divergent). In the present paper, the nature of the scale variables and their relations to resolutions and differential elements are specified in the non-relativistic case (fractal space). We show that, owing to the scale-dependence which it induces, non-differentiability involves a fundamental two-valuedness of the mean derivatives. Since, in the scale relativity framework, the wave function is a manifestation of the velocity field of fractal space-time geodesics, the two-valuedness of velocities leads to write them in terms of complex numbers, and yields therefore the complex nature of the wave function, from which the usual expression of the Schrödinger equation can be derived.

    2016-01-01

    Autocatalytic chemical reactions are widely studied as models of biological processes and to better understand the origins of life on Earth. Minimal self-reproducing amphiphiles have been developed in this context and as an approach to de novo “bottom–up” synthetic protocells. How chemicals come together to produce living systems, however, remains poorly understood, despite much experimentation and speculation. Here, we use ultrasensitive label-free optical microscopy to visualize the spontaneous emergence of an autocatalytic system from an aqueous mixture of two chemicals. Quantitative, in situ nanoscale imaging reveals heterogeneous self-reproducing aggregates and enables the real-time visualization of the synthesis of new aggregates at the reactive interface. The aggregates and reactivity patterns observed vary together with differences in the respective environment. This work demonstrates how imaging of chemistry at the nanoscale can provide direct insight into the dynamic evolution of nonequilibrium systems across molecular to microscopic length scales.

    The large-scale structural ingredients of the brain and neural connectomes have been identified in recent years. These are, similar to the features found in many other real networks: the arrangement of brain regions into modules and the presence of highly connected regions (hubs) forming rich-clubs. Here, we examine how modules and hubs shape the collective dynamics on networks and we find that both ingredients lead to the emergence of complex dynamics. Comparing the connectomes of C. elegans, cats, macaques and humans to surrogate networks in which either modules or hubs are destroyed, we find that functional complexity always decreases in the perturbed networks. A comparison between simulated and empirically obtained resting-state functional connectivity indicates that the human brain, at rest, lies in a dynamical state that reflects the largest complexity its anatomical connectome can host. Last, we generalise the topology of neural connectomes into a new hierarchical network model that successfully combines modular organisation with rich-club forming hubs. This is achieved by centralising the cross-modular connections through a preferential attachment rule. Our network model hosts more complex dynamics than other hierarchical models widely used as benchmarks. PMID:27917958

  14. Emergence of a New Population of Rathayibacter toxicus: An Ecologically Complex, Geographically Isolated Bacterium

    2016-01-01

    Rathayibacter toxicus is a gram-positive bacterium that infects the floral parts of several Poaceae species in Australia. Bacterial ooze is often produced on the surface of infected plants and bacterial galls are produced in place of seed. R. toxicus is a regulated plant pathogen in the U.S. yet reliable detection and diagnostic tools are lacking. To better understand this geographically-isolated plant pathogen, genetic variation as a function of geographic location, host species, and date of isolation was determined for isolates collected over a forty-year period. Discriminant analyses of recently collected and archived isolates using Multi-Locus Sequence Typing (MLST) and Inter-Simple Sequence Repeats (ISSR) identified three populations of R. toxicus; RT-I and RT-II from South Australia and RT-III from Western Australia. Population RT-I, detected in 2013 and 2014 from the Yorke Peninsula in South Australia, is a newly emerged population of R. toxicus not previously reported. Commonly used housekeeping genes failed to discriminate among the R. toxicus isolates. However, strategically selected and genome-dispersed MLST genes representing an array of cellular functions from chromosome replication, antibiotic resistance and biosynthetic pathways to bacterial acquired immunity were discriminative. Genetic variation among isolates within the RT-I population was less than the within-population variation for the previously reported RT-II and RT-III populations. The lower relative genetic variation within the RT-I population and its absence from sampling over the past 40 years suggest its recent emergence. RT-I was the dominant population on the Yorke Peninsula during the 2013–2014 sampling period perhaps indicating a competitive advantage over the previously detected RT-II population. The potential for introduction of this bacterial plant pathogen into new geographic areas provide a rationale for understanding the ecological and evolutionary trajectories of R. toxicus

    Aid agencies (AAs) provide a range of humanitarian and health related assistance globally. However, the trust placed on them is eroding. Evidence for this includes accusations of a decline in their humanitarianism, and the increasing number of conflicts with host states. An analysis of the concerns expressed yields two possible reasons: a relative lack of transparency of their work and weak accountability mechanisms. This is further supported by the existing milieu: an absence of internationally accepted instrument or mechanism to check the credentials of INGOs and an opaque system of close links between some of the INGOs and their donors. The article suggests two global strategies to tackle these issues: (a) Increase transparency by establishing a global register of aid agencies. This should have basic information: their main goals and activities, countries they are active in, number of employees, annual turnover of funds (updated regularly), principal financing sources and nature of links with donors. This could also be available as printed manual that should be freely available to client countries. (b) Ensure accountability by developing templates of fair legal instruments (to facilitate and regulate work), and a set of generic rules and procedures of engagement for the interactions between agencies and client states. These should be institutionalized within the regulatory frameworks of countries and included in the Codes of Conduct of NGOs. PMID:22110413

  17. Predator attack rate evolution in space: the role of ecology mediated by complex emergent spatial structure and self-shading.

    2013-11-01

    Predation interactions are an important element of ecological communities. Population spatial structure has been shown to influence predator evolution, resulting in the evolution of a reduced predator attack rate; however, the evolutionary role of traits governing predator and prey ecology is unknown. The evolutionary effect of spatial structure on a predator's attack rate has primarily been explored assuming a fixed metapopulation spatial structure, and understood in terms of group selection. But endogenously generated, emergent spatial structure is common in nature. Furthermore, the evolutionary influence of ecological traits may be mediated through the spatial self-structuring process. Drawing from theory on pathogens, the evolutionary effect of emergent spatial structure can be understood in terms of self-shading, where a voracious predator limits its long-term invasion potential by reducing local prey availability. Here we formalize the effects of self-shading for predators using spatial moment equations. Then, through simulations, we show that in a spatial context self-shading leads to relationships between predator-prey ecology and the predator's attack rate that are not expected in a non-spatial context. Some relationships are analogous to relationships already shown for host-pathogen interactions, but others represent new trait dimensions. Finally, since understanding the effects of ecology using existing self-shading theory requires simplifications of the emergent spatial structure that do not apply well here, we also develop metrics describing the complex spatial structure of the predator and prey populations to help us explain the evolutionary effect of predator and prey ecology in the context of self-shading. The identification of these metrics may provide a step towards expansion of the predictive domain of self-shading theory to more complex spatial dynamics.

    This research program explored the efficacy of using molecular-level manipulation, imaging and scanning tunneling spectroscopy in conjunction with supersonic molecular beam gas-surface scattering to significantly enhance our understanding of chemical processes occurring on well-characterized interfaces. One program focus was on the spatially-resolved emergent behavior of complex reaction systems as a function of the local geometry and density of adsorbate-substrate systems under reaction conditions. Another focus was on elucidating the emergent electronic and related reactivity characteristics of intentionally constructed single and multicomponent atom- and nanoparticle-based materials. We also examined emergent chirality and self-organization in adsorbed molecular systems where collective interactions between adsorbates and the supporting interface lead to spatial symmetry breaking. In many of these studies we combined the advantages of scanning tunneling (STM) and atomic force (AFM) imaging, scanning tunneling local electronic spectroscopy (STS), and reactive supersonic molecular beams to elucidate precise details of interfacial reactivity that had not been observed by more traditional surface science methods. Using these methods, it was possible to examine, for example, the differential reactivity of molecules adsorbed at different bonding sites in conjunction with how reactivity is modified by the local configuration of nearby adsorbates. At the core of this effort was the goal of significantly extending our understanding of interfacial atomic-scale interactions to create, with intent, molecular assemblies and materials with advanced chemical and physical properties. This ambitious program addressed several key topics in DOE Grand Challenge Science, including emergent chemical and physical properties in condensed phase systems, novel uses of chemical imaging, and the development of advanced reactivity concepts in combustion and catalysis including carbon

  19. Emergency Management of High-Energy Shell Fragment Midface Complex Injuries.

    Distinctive mechanisms of heavy artillery and improvised explosive device detonation result in a blast and "spray" of high-energy fragments of diverse shapes, sizes, and characteristics. Associated midface complex injuries differ in both severity and complexity of the anatomical structures involved. Management challenges begin with lifesaving, which is complicated by airway compromise, severe hemorrhage, and unique injuries of the maxillae, nose, and naso-orbitoethmoid.The patients presented fragment impact on the face lateral side directed to other side leads to tissues blown away at the point of high-energy exits, while no survival seen of enface shrapnel hit directed antroposterior toward "cervical spine, intracranial, internal and external carotid arteries and internal jugular vein."Twenty-two patients were selected from unquantified patients who had sustained massive midface shell fragment injuries. To preserve midface architecture, healing, and function, iodoform paste on ribbon gauze packs were utilized successfully. An iodoform paste on ribbon gauze pack serves the dual purpose of preserving the shape and scaffolding of the crushed maxillary sinus wall and buttresses fragments in position for healing. It also acts as a wet pack dressing for denuded bone fragments, stopping bleeding and having antimicrobial properties for severely lacerated wounds. For total or partial nasal tissue loss, a successful procedure consists of definitive early scaffolding stabilization using an intranasal, modified portex tracheostomy tube stent to preserve the internal shape of the nasal pyramid.

    We study the ground-state phase diagram of the quantum spin-1 /2 Heisenberg model on the kagome lattice with first- (J1<0 ) , second- (J2<0 ) , and third-neighbor interactions (Jd>0 ) by means of analytical low-energy field theory and numerical density-matrix renormalization group (DMRG) studies. The results offer a consistent picture of the Jd-dominant regime in terms of three sets of spin chains weakly coupled by the ferromagnetic interchain interactions J1 ,2. When either J1 or J2 is much stronger than the other one, the model is found to support one of two cuboctohedral phases, cuboc1, and cuboc2. These cuboc states host noncoplanar long-ranged magnetic order and possess finite scalar spin chirality. However, in the compensated regime J1≃J2 , a valence bond crystal phase emerges between the two cuboc phases. We find excellent agreement between an analytical theory based on coupled spin chains and unbiased DMRG calculations, including at a very detailed level of comparison of the structure of the valence bond crystal state. To our knowledge, this is the first such comprehensive understanding of a highly frustrated two-dimensional quantum antiferromagnet. We find no evidence of either the one-dimensional gapless spin liquid or the chiral spin liquids, which were previously suggested by parton mean-field theories.

  1. T-box factors: insights into the evolutionary emergence of the complex heart.

    PubMed

    Hariri, Fadi; Nemer, Mona; Nemer, Georges

    2012-11-01

    The heart as a functional organ first appeared in bilaterians as a single peristaltic pump and evolved through arthropods, fish, amphibians, and finally mammals into a four-chambered engine controlling blood-flow within the body. The acquisition of cardiac complexity in the evolving heart was a product of gene duplication events and the co-option of novel signaling pathways to an ancestral cardiac-specific gene network. T-box factors belong to an evolutionary conserved family of transcriptional regulators with diverse roles in development. Their regulatory functions are integral in the initiation and potentiation of heart development, and mutations in these genes are associated with congenital heart defects. In this review we will discuss the evolutionary conserved cardiac regulatory functions of this family as well as their implication in disease in an aim to facilitate future gene-targeted and regenerative therapeutic remedies.

  2. Emergence of hydrogen bonds from molecular dynamics simulation of substituted N-phenylthiourea-catechol oxidase complex.

    A series of N-phenylthiourea derivatives was built starting from the X-ray structure in the molecular mechanics framework and the interaction profile in the complex with the catechol oxidase was traced using molecular dynamics simulation. The results showed that the geometry and interactions between ligand and receptor were highly related to the position of the substituted side chains of phenyl moiety. At the end of molecular dynamics run, a concentrated multicenter hydrogen bond was created between the substituted ligand and receptor. The conformation of the ligand itself were also restricted in the receptor pocket. Furthermore, the simulation time of 50 ns were found to be long enough to explore the relevant conformational space and the stationary behavior of the molecular dynamic could be observed.

    2011-01-01

    This article provides an overview of US humanitarian relief efforts in Haiti following the earthquake on January 12, 2010. Humanitarian aid arrived rapidly from many sources and was largely provided by organized and skilled humanitarian volunteers. There are however multiple impacts on the existing health care systems, as well as the pharmaceutical and medical supply chain created by massive relief efforts involving personnel, medicines, supplies and equipment that should be considered even in the immediate post-disaster period. Additionally the consequences of short-term medical missions by secular and non-secular NGOs should be considered carefully both in the post-disaster period and as ongoing support to underserved populations.

    High-precision accelerator mass spectrometer (AMS) (14)C dates of scarlet macaw (Ara macao) skeletal remains provide the first direct evidence from Chaco Canyon in northwestern New Mexico that these Neotropical birds were procured from Mesoamerica by Pueblo people as early as ∼ A.D. 900-975. Chaco was a prominent prehistoric Pueblo center with a dense concentration of multistoried great houses constructed from the 9th through early 12th centuries. At the best known great house of Pueblo Bonito, unusual burial crypts and significant quantities of exotic and symbolically important materials, including scarlet macaws, turquoise, marine shell, and cacao, suggest societal complexity unprecedented elsewhere in the Puebloan world. Scarlet macaws are known markers of social and political status among the Pueblos. New AMS (14)C-dated scarlet macaw remains from Pueblo Bonito demonstrate that these birds were acquired persistently from Mesoamerica between A.D. 900 and 1150. Most of the macaws date before the hypothesized apogeal Chacoan period (A.D. 1040-1110) to which they are commonly attributed. The 10th century acquisition of these birds is consistent with the hypothesis that more formalized status hierarchies developed with significant connections to Mesoamerica before the post-A.D. 1040 architectural florescence in Chaco Canyon.

    Summary Recent experimental evidences support the existence of an increasingly complex and multifaceted interaction between viruses and the microRNA-guided RNA silencing machinery of human cells. The discovery of small interfering RNAs (siRNAs), which are designed to mediate cleavage of specific messenger RNAs (mRNAs), prompted virologists to establish therapeutic strategies based on siRNAs with the aim to suppress replication of several viruses, including human immunodeficiency virus type 1 (HIV-1). It has been appreciated only recently that viral RNAs can also be processed endogenously by the microRNA-generating enzyme Dicer or recognized by cellular miRNAs, in processes that could be viewed as an adapted antiviral defense mechanism. Known to repress mRNA translation through recognition of specific binding sites usually located in their 3′ untranslated region, miRNAs of host or viral origin may exert regulatory effects towards host and/or viral genes and influence viral replication and/or the host response to viral infection. This article summarizes our current state of knowledge on the relationship between HIV-1 and miRNA-guided RNA silencing, and discusses the different aspects of their interaction. PMID:19301659

    A continental-scale model of Holocene Australian hunter-gatherer demography and mobility is generated using radiocarbon data and geospatial techniques. Results show a delayed expansion and settlement of much of Australia following the termination of the late Pleistocene until after 9,000 years ago (or 9ka). The onset of the Holocene climatic optimum (9-6ka) coincides with rapid expansion, growth and establishment of regional populations across ~75% of Australia, including much of the arid zone. This diffusion from isolated Pleistocene refugia provides a mechanism for the synchronous spread of pan-continental archaeological and linguistic attributes at this time (e.g. Pama-Nyungan language, Panaramitee art style, backed artefacts). We argue longer patch residence times were possible at the end of the optimum, resulting in a shift to more sedentary lifestyles and establishment of low-level food production in some parts of the continent. The onset of El Niño - Southern Oscillation (ENSO; 4.5-2ka) restricted low-level food production, and resulted in population fragmentation, abandonment of marginal areas, and reduction in ranging territory of ~26%. Importantly, climate amelioration brought about by more pervasive La Niña conditions (post-2ka), resulted in an intensification of the mobility strategies and technological innovations that were developed in the early- to mid-Holocene. These changes resulted in population expansion and utilization of the entire continent. We propose that it was under these demographically packed conditions that the complex social and religious societies observed at colonial contact were formed. PMID:26083101

    Distinct clones of methicillin-resistant Staphylococcus aureus (MRSA) have emerged as important causes of infection in individuals who have exposure to livestock (livestock-associated MRSA; LA-MRSA). Clonal complex 398 (CC398) is the most prevalent LA-MRSA clone, and has been reported from several geographical settings, including Europe, the Americas and Asia. To understand the factors contributing to the global dissemination of this clone, we analysed CC398 MRSA isolates from New Zealand (NZ), a geographically isolated country with an economy strongly dependent on livestock farming. We supplemented the NZ CC398 MRSA collection with global datasets of CC398 MRSA and CC398 methicillin-susceptible S. aureus. Here, we demonstrate multiple sporadic incursions of CC398 MRSA into NZ, as well as recent importation and spread of a swine-associated clade related to the European LA-MRSA lineage. Within a larger global phylogenomic framework, Bayesian modelling suggested that this NZ clade emerged in the late 2000s, with a probable origin in swine from Western Europe. Elucidating the factors responsible for the incursion and spread of LA-MRSA in geographically distant regions, such as NZ, provides important insights into global pathways of S. aureus transmission, and will inform strategies to control importation and spread.

    Humanitarian relief work is a growing field characterized by ongoing exposure to primary and secondary trauma, which has implications for workers' occupational mental health. This paper reviews and summarizes research to date on mental health effects of relief work. Twelve studies on relief workers and 5 studies on organizations that employ relief workers are examined to determine whether relief work is a risk factor for trauma-related mental illness. Although studies are inconsistent regarding methods and outcomes documenting trauma-related mental illness among relief workers, it appears that relief workers, compared with the general population, experience elevated trauma rates and suffer from more posttraumatic stress disorder, depression, and anxiety. Organizations that employ relief workers have varying approaches to train for these risks, and more support in the field is needed.

    Manual prodding is still one of the most utilized procedures for identifying buried landmines during humanitarian demining activities. However, due to the high number of accidents reported during its practice, it is considered an outmoded and risky procedure and there is a general consensus about the need of introducing upgrades for enhancing the safety of human operators. With the aim of contributing to reduce the number of demining accidents, this paper presents an intelligent multisensory system for training operators in the use of prodders. The proposed tool is able to provide to deminers useful information in two critical issues: (a) the amount of force exerted on the target and if it is greater than the safe limit and, (b) to alert them when the angle of insertion of the prodder is approaching or exceeding a certain dangerous limit. Results of preliminary tests show the feasibility and reliability of the proposed design and highlight the potential benefits of the tool. PMID:27347963

    Introduction: The objective of this study is to identify the effectiveness characteristics, review the definition of them, and develop a conceptual mapping of existing domains in the field of International Humanitarian Assistance (IHA). Methods: We conducted a systematic review and searched the major databases (Science Direct, Scopus, Springer and Pubmed) and grey literature, including references of potentially eligible articles and conference proceedings through March 2015. Articles were included if they focused on IHA effectiveness. Reviewers independently identified the eligible studies and extracted data. Results: 10 studies were included and 48 characteristics were identified. There is a lack of scientific studies and agreement on the characteristics of IHA effectiveness.  Conclusion: This study could be the step toward an understanding of IHA effectiveness characteristics and its definitions with the findings making a base line for more research in this area.  PMID:26981325

    ALIS is a hand-held dual sensor developed by Tohoku University, Japan since 2002. Dual sensor is a general name of sensor for humanitarian demining, which are equipped with metal detector and GPR. ALIS is only one hand-held dual sensor, which can record the sensor position with sensor signals. Therefore, the data can be processed after data acquisition, and can increase the imaging capability. ALIS has been tested in some mine affected courtiers including Afghanistan (2004), Egypt(2005), Croatia(2006-) and Cambodia(2007-). Mine fields at each country has different conditions and soil types. Therefore testes at the real mine fields are very important. ALIS has detected more than 30 AP-Mines in evaluation test in Cambodia held in 2009.

    Objective To explore the characteristics, motivations, ideologies, experience and perspectives of experienced medical humanitarian workers. Design We applied a qualitative descriptive approach and conducted in-depth semistructured interviews, containing open-ended questions with directing probes, with 44 experienced international medical aid workers from a wide range of humanitarian organisations. Interviews were coded and analysed, and themes were developed. Setting International non-governmental organisations (INGOs) and United Nations (UN). Results 61% of participants were female; mean age was 41.8 years with an average of 11.8 years of humanitarian work experience with diverse major INGOs. Significant core themes included: population's rights to assistance, altruism and solidarity as motives; self-identification with the mission and directives of INGOs; shared personal and professional morals fostering collegiality; accountability towards beneficiaries in areas of programme planning and funding; burnout and emotional burdens; uncertainties in job safety and security; and uneasiness over changing humanitarian principles with increasing professionalisation of aid and shrinking humanitarian access. While dissatisfied with overall aid operations, participants were generally satisfied with their work and believed that they were well-received by, and had strong relationships with, intended beneficiaries. Conclusions Despite regular use of language and ideology of rights, solidarity and concepts of accountability, tension exists between the philosophy and practical incorporation of accountability into operations. To maintain a humanitarian corps and improve aid worker retention, strategies are needed regarding management of psychosocial stresses, proactively addressing militarisation and neo-humanitarianism, and nurturing individuals’ and organisations’ growth with emphasis on humanitarian principles and ethical practices, and a culture of internal debate

  2. Failing to protect humanitarian workers: lessons from Britain and Voluntary Aid Detachments in the Second World War.

    2017-03-19

    This paper draws on official records of international and British organizations, newspaper reports, and volunteer memoirs to study the failure to protect humanitarian workers in the Second World War. The Second World War saw a significant expansion in the use of air warfare and flying missiles and these technological advances posed a grave threat to civilians and humanitarian workers. In this context, the International Committee of the Red Cross advocated unsuccessfully to restrict air warfare and create safe hospital zones. The British Government grappled with the tension between military and humanitarian objectives in setting its bombardment policy. Ultimately, humanitarian principles were neglected in pursuit of strategic aims, which endangered civilians and left humanitarian workers particularly vulnerable. British Voluntary Aid Detachment nurses experienced more than six-fold greater fatality rates than civil defence workers and the general population. The lessons from failures to protect humanitarian workers in the face of evolutions in warfare remain profoundly relevant.

  3. Complex Controls on Groundwater Quality in Growing Mid-sized Cities: A Case Study Focused on Nitrate and Emerging Contaminants

    Many regions rely on quality groundwater to support urban growth. Groundwater quality often responds in a complex manner to stressors such as land use change, climate change, or policy decisions. Urban growth patterns in mid-sized cities, especially ones that are growing urban centers in water-limited regions in the western US, control and are controlled by water availability and its quality. We present a case study from southeastern Idaho where urban growth over the past 20 years has included significant ex-urban expansion of houses that rely on septic systems rather than city sewer lines for their wastewater treatment. Septic systems are designed to mitigate some contaminants, but not others. In particular, nitrates and emerging contaminants, such as pharmaceuticals, are not removed by most septic systems. Thus, even well-maintained septic systems at sufficiently high densities can impact down gradient water quality. Here we present patterns of nitrate concentrations over the period from 1985-2015 from the Lower Portneuf River Valley in southeastern Idaho. Concentrations vary from 0.03 to 27.09 nitrate-nitrogen mg/L, with average values increasing significantly over the 30 year time period from 3.15 +/- 0.065 to 3.57 +/- 0.43 mg/L. We examine temporal changes in locations of nitrate hotspots, and present pilot data on emerging contaminants of concern. Initial results suggest that high nitrate levels are generally associated with higher septic densities, but that this pattern is influenced by legacy agricultural uses and strongly controlled by underlying aquifer properties. Future work will include more detailed hydrological modeling to predict changes in hotspot locations under potential climate change scenarios.

    Background The fields of expertise of natural disasters and complex emergencies (CEs) are quite distinct, with different tools for mitigation and response as well as different types of competent organizations and qualified professionals who respond. However, natural disasters and CEs can occur concurrently in the same geographic location, and epidemics can occur during or following either event. The occurrence and overlap of these three types of events have not been well studied. Methods All natural disasters, CEs and epidemics occurring within the past decade (1995–2004) that met the inclusion criteria were included. The largest 30 events in each category were based on the total number of deaths recorded. The main databases used were the Emergency Events Database for natural disasters, the Uppsala Conflict Database Program for CEs and the World Health Organization outbreaks archive for epidemics. Analysis During the past decade, 63% of the largest CEs had ≥1 epidemic compared with 23% of the largest natural disasters. Twenty-seven percent of the largest natural disasters occurred in areas with ≥1 ongoing CE while 87% of the largest CEs had ≥1 natural disaster. Conclusion Epidemics commonly occur during CEs. The data presented in this article do not support the often-repeated assertion that epidemics, especially large-scale epidemics, commonly occur following large-scale natural disasters. This observation has important policy and programmatic implications when preparing and responding to epidemics. There is an important and previously unrecognized overlap between natural disasters and CEs. Training and tools are needed to help bridge the gap between the different type of organizations and professionals who respond to natural disasters and CEs to ensure an integrated and coordinated response.

    Insecticide-treated mosquito nets (ITN) provide excellent protection against malaria; however, they have a number of shortcomings that are particularly evident in politically unstable countries or countries at war: not everyone at risk can necessarily afford a net, nets may be difficult to obtain or import, nets may not be suitable for migrants or refugees sleeping under tents or plastic shelter. There is a need to develop cheaper, locally appropriate alternatives for the most impoverished and for victims of complex emergencies. Afghan women, in common with many Muslim peoples of Asia, wear a veil or wrap known as a chaddar to cover the head and upper body. This cloth doubles as a sheet at night, when they are used by both sexes. A randomized controlled trial was undertaken in which 10% of the families of an Afghan refugee camp (population 3950) in north-western Pakistan had their chaddars and top-sheets treated with permethrin insecticide at a dosage of 1 g/m2 while a further 10% had their chaddars treated with placebo formulation. Malaria episodes were recorded by passive case detection at the camp's health centre. From August to November the odds of having a falciparum or vivax malaria episode were reduced by 64% in children aged 0-10 years and by 38% in refugees aged < 20 years in the group using permethrin-treated chaddars and top-sheets. Incidence in refugees over 20 years of age was not significantly reduced. The cost of the permethrin treatment per person protected (US$0.17) was similar to that for treating bednets (and cost only 10-20% of the price of a new bednet). An entomological study simulating real-life conditions indicated that host-seeking mosquitoes were up to 70% less successful at feeding on men sleeping under treated chaddars and some were killed by the insecticide. Permethrin-treated top-sheets and blankets should provide appropriate and effective protection from malaria in complex emergencies. In Islamic and non-Islamic countries in Asia

While coordination and control of the humanitarian sector has plagued the response to every major crisis, concerns highlighted by the 2010 Haitian earthquake response further catalyzed and accelerated the need to ensure competency-based professionalization of the humanitarian health care work force. The Harvard Humanitarian Initiative sponsored an independent survey of established academically affiliated training centers in North America that train humanitarian health care workers to determine their individual training center characteristics and preferences in the potential professionalization process. The survey revealed that a common thread of profession-specific skills and core humanitarian competencies were being offered in both residential and online programs with additional programs offering opportunities for field simulation experiences and more advanced degree programs. This study supports the potential for the development of like-minded academic affiliated and competency-based humanitarian health programs to organize themselves under ELRHA's regional "consultation hubs" worldwide that can assist and advocate for improved education and training opportunities in less served developing countries.

    SUMMARY Demographic trends globally point in the direction of increasing numbers of older people with serious and chronic mental disorders, such as bipolar disorder (BD). While there has been growing sophistication and understanding in treatments for BD generally, data specific to older people with BD are limited. Recent reviews, secondary analyses and some new research confirm complexity and aging-related issues relevant to later-life BD. Confounding variables that must be considered when studying older BD individuals include clinical heterogeneity, medical comorbidity, cognitive impairment and concomitant psychotropic medication. This article will review current and emerging data on aging- and disease-related issues that complicate assessment and treatment of older individuals with BD. We will discuss common comorbid medical conditions that affect BD elders, how aging may affect cognition and treatment, including the effects of lithium and other psychotropic drugs on the aging brain, and recent research using neuroimaging techniques that may shed light on understanding the mechanisms of illness progression and on treatment response. Finally, we will discuss implications for future work in geriatric BD. PMID:24999372

    Bni4 is a scaffold protein in the yeast Saccharomyces cerevisiae that tethers chitin synthase III to the bud neck by interacting with septin neck filaments and with Chs4, a regulatory subunit of chitin synthase III. We show herein that Bni4 is also a limiting determinant for the targeting of the type 1 serine/threonine phosphatase (Glc7) to the bud neck. Yeast cells containing a Bni4 variant that fails to associate with Glc7 fail to tether Chs4 to the neck, due in part to the failure of Bni4V831A/F833A to localize properly. Conversely, the Glc7-129 mutant protein fails to bind Bni4 properly and glc7-129 mutants exhibit reduced levels of Bni4 at the bud neck. Bni4 is phosphorylated in a cell cycle-dependent manner and Bni4V831A/F833A is both hyperphosphorylated and mislocalized in vivo. Yeast cells lacking the protein kinase Hsl1 exhibit increased levels of Bni4-GFP at the bud neck. GFP-Chs4 does not accumulate at the incipient bud site in either a bni4::TRP1 or a bni4V831A/F833A mutant but does mobilize to the neck at cytokinesis. Together, these results indicate that the formation of the Bni4-Glc7 complex is required for localization to the site of bud emergence and for subsequent targeting of chitin synthase. PMID:12529424

    Humanitarian health programs frequently focus on immediate relief and are supply side oriented or donor driven. More emphasis should be placed on long-term development projects that engage local community leaders to ensure sustainable change in health care systems. With the Emergency Medicine Educational Exchange (EMEDEX) International Rescue, Recover, Rebuild initiative in Northeast Haiti as a model, this paper discusses the opportunities and challenges in using community-based development to establish emergency medical systems in resource-limited settings.

    Introduction: As a result of the gaps in humanitarian response highlighted by several reports, the international community called for an increased professionalization of humanitarian aid workers. This paper describes a pilot project by an Italian university and a non-profit, non-governmental organization to implement a medical apprenticeship in low-income countries during Anesthesia and Intensive Care Medicine residencies. Methods: Before deployment, participants were required to complete a dedicated online training course about safety and security in the field, principles of anesthesia at the district hospital level, emergency and essential surgical care, essentials of medical treatment in resource-constrained environments and psychological support in emergencies. Results: At the end of the program, a qualitative self-evaluation questionnaire administered to participants highlighted how the project allowed the participants to advance their professional skills when working in a low-resource environment, while also mastering their adapting skills and the ability to interact and cooperate with local healthcare personnel. The project also proved to be a means for personal growth, making these experiences a recommendation for all residents as a necessary step for the professionalization of healthcare personnel involved in humanitarian aid.

  12. Humanitarian agencies and authoritarian states: a symbiotic relationship?

    PubMed

    del Valle, Hernan; Healy, Sean

    2013-10-01

    The relationship between humanitarian agencies and authoritarian states is of growing concern to Médecins Sans Frontières (MSF), given the recurring difficulties experienced in negotiating access and implementing operations in such contexts. The effort to negotiate and gain approval from states to operate on their territory prompts reflection on the sources of legitimacy for action. Drawing on direct field examples in two countries only very rarely examined--Turkmenistan and Uzbekistan--this paper explores MSF's attempts to offer live-saving medical care there. It shows that successful access negotiations hinged heavily on demonstrating added value (medical relevance) while simultaneously building relationships with authorities, identifying possible allies within health ministries, and hoping that such measures could promote a level of acceptance or trust needed to operate. It is clear that the operational space achieved is bound to remain limited and fragile, and that many compromises have to be considered and judged against ethical principles and the overall impact of the intervention.

  13. Geoengineering: re-making climate for profit or humanitarian intervention?

    PubMed

    Buck, Holly Jean

    2012-01-01

    Climate engineering, or geoengineering, refers to large-scale climate interventions to lower the earth's temperature, either by blocking incoming sunlight or removing carbon dioxide from the biosphere. Regarded as ‘technofixes’ by critics, these strategies have evoked concern that they would extend the shelf life of fossil-fuel driven socio-ecological systems for far longer than they otherwise would, or should, endure. A critical reading views geoengineering as a class project that is designed to keep the climate system stable enough for existing production systems to continue operating. This article first examines these concerns, and then goes on to envision a regime driven by humanitarian agendas and concern for vulnerable populations, implemented through international development and aid institutions. The motivations of those who fund research and implement geoengineering techniques are important, as the rationale for developing geoengineering strategies will determine which techniques are pursued, and hence which ecologies are produced. The logic that shapes the geoengineering research process could potentially influence social ecologies centuries from now.

  14. Magnetic sensing techniques for humanitarian ordnance detection and discrimination

    2011-06-01

    Detection and discrimination of unexploded ordnance (UXO) in areas of prior conflict is of high importance to the international community and the United States government. For humanitarian applications, sensors and processing methods need to be robust, reliable, and easy to train and implement using indigenous UXO removal personnel. This paper focuses on magnetometer sensing techniques, processing, and operation for UXO detection and discrimination applications. Specifically, we discuss the collection, processing, and discrimination of data collected using the PACMAG man-portable system consisting of arrays of sensitive total-field magnetometers, global positioning (GPS) combined with digital odometers, and a data acquisition system. We outline preliminary standard operating procedures for optimal collection of UXO-induced magnetic fields and associated position data using either a GPS, or odometer when surveying in GPS-denied areas. Processing techniques such as gridding and filtering, target picking, and discrimination lead to estimates of target size and location. Emphasis is placed on simplifying the production of magnetometer hardware and software for use by minimally-trained personnel with no advanced knowledge of magnetic sensing and geophysics.

    Existing tools for evaluating psychosocial interventions (un-validated self-reporting questionnaires) are not ideal for use in non-Western conflict settings. We implement a generic method of treatment evaluation, using client and counsellor feedback, in 18 projects in non-Western humanitarian settings. We discuss our findings from the perspective of validity and suggestions for future research. A retrospective analysis is executed using data gathered from psychosocial projects. Clients (n = 7,058) complete two (complaints and functioning) rating scales each session and counsellors rate the client’s status at exit. The client-completed pre- and post-intervention rating scales show substantial changes. Counsellor evaluation of the clients’ status shows a similar trend in improvement. All three multivariable models for each separate scale have similar associations between the scales and the investigated variables despite different cultural settings. The validity is good. Limitations are: ratings give only a general impression and clinical risk factors are not measured. Potential ceiling effects may influence change of scales. The intra and inter-rater reliability of the counsellors’ rating is not assessed. The focus on client and counsellor perspectives to evaluate treatment outcome seems a strong alternative for evaluation instruments frequently used in psychosocial programming. The session client rated scales helps client and counsellor to set mutual treatment objectives and reduce drop-out risk. Further research should test the scales against a cross-cultural valid gold standard to obtain insight into their clinical relevance. PMID:27315263

  16. Enforcement costs: some humanitarian alternatives to stronger patent rights.

    PubMed

    Trotter, Andrew

    2012-01-01

    Diseases that cause comparatively few problems in developed countries kill millions of people in the Third World each year. In many cases, people die because they cannot afford the medication needed to save their lives. In others, there are simply no drugs available because there are no wealthy western patients to justify pharmaceutical companies investing in a cure. This reveals a deep-seated problem within the patent system and the pharmaceutical industry that emphasises markets and profits at the expense of health and global welfare. Global efforts have seen substantial improvements in access to medicines in isolated areas, but with international agreements driving towards stronger patent protection and the expiry date for the TRIPS grace period fast approaching, it is time to consider alternatives which will allow the patent system to work for the humanitarian cause rather than against it. This paper considers two such problems in the patent system and pharmaceutical industry - prohibitive pricing and misdirected incentives - to offer a mode of regulation and enforcement that will support both a viable pharmaceutical industry and the human right to health and medication.

  17. 'The deserving': Moral reasoning and ideological dilemmas in public responses to humanitarian communications.

    PubMed

    Seu, Irene Bruna

    2016-12-01

    This study investigates everyday moral reasoning in relation to donations and prosocial behaviour in a humanitarian context. The discursive analysis focuses on the principles of deservingness which members of the public use to decide who to help and under what conditions. The study discusses three repertoires of deservingness - 'seeing a difference', 'waiting in queues', and 'something for nothing' - to illustrate participants' dilemmatic reasoning and to examine how the position of 'being deserving' is negotiated in humanitarian crises. Discursive analyses of these dilemmatic repertoires of deservingness identify the cultural and ideological resources behind these constructions and show how humanitarianism intersects and clashes with other ideologies and value systems. The data suggest that a neoliberal ideology, which endorses self-gratification, materialistic and individualistic ethics, and cultural assimilation of helper and receiver play important roles in decisions about humanitarian helping. The study argues for the need for psychological research to engage more actively with the dilemmas involved in the moral reasoning related to humanitarianism and to contextualize decisions about giving and helping within the sociocultural and ideological landscape in which the helper operates.

  18. Dividing disasters in Aceh, Indonesia: separatist conflict and tsunami, human rights and humanitarianism.

    PubMed

    Zeccola, Paul

    2011-04-01

    This paper examines the interface between human rights and humanitarian action in the context of the conflict and tsunami in Aceh, Indonesia, between 1998 and 2007. It looks at the challenges international humanitarian non-governmental organisations (NGOs) faced as they engaged in human rights work in the conflict period and in conflict-related activities in the post-tsunami period. The paper argues that many large NGOs may have compromised what some would hold to be essential principles for humanitarian action because of domestic political concerns, donor restrictions and resistance among certain NGO chiefs. In contrast with the pre-tsunami period, in which NGOs worked for years amid military operations, in the post-tsunami period NGOs were decidedly apolitical, neglecting the conflict in their tsunami response--despite significant developments that permitted greater political engagement in Aceh's post-conflict transformation. The evidence suggests that NGOs are challenged in contextualising humanitarian responses and that there is a need to underscore donor flexibility and independence in humanitarian action.

    "Molecular flasks" are well-defined supramolecular cages that can encapsulate one or more molecular guests within their cavities and, in so doing, change the physical properties and reactivities of the guests. Although molecular flasks are powerful tools for manipulating matter on the nanoscale, most of them are limited in their scope because of size restrictions. Recently, however, increasingly large and diverse supramolecular cages have become available with enough space in their cavities for larger chemical systems such as polymers, nanoparticles, and biomolecules. Here we report how a class of metallosupramolecular cages known as M12L24 polyhedra have been adapted to serve as nanometer-scale containers for solutions of a pseudorotaxane host-guest complex based on a tetracationic cyclophane host, cyclobis(paraquat-p-phenylene) (CBPQT(4+)), and a 1,5-dioxynaphthalene (DNP) guest. Remarkably, the hierarchical integration of pseudorotaxanes and M12L24 superhosts causes the system to express stimulus-responsive behavior, a property which can be described as emergent because neither the DNP⊂CBPQT(4+) nor the M12L24 assemblies exhibit this behavior independently. The DNP-containing M12L24 molecular flasks are effectively "sealed off" to CBPQT(4+) until ions are added as a stimulus to "open" them. The electrolyte stimulus reduces the electrostatic screening distance in solution, allowing favorable DNP⊂CBPQT(4+) host-guest interactions to overcome repulsive Coulombic interactions between the cationic M12L24 cages and CBPQT(4+) rings. This unusual example of ion-gated transport into chemical nanocontainers is reminiscent of transmembrane ion channels which act as gates to the cell, with the important difference that this system is reversible and operates at equilibrium.

  20. Structural Vulnerability Among Migrating Women and Children Fleeing Central America and Mexico: The Public Health Impact of “Humanitarian Parole”

    Valdez, Elizabeth Salerno; Valdez, Luis A.; Sabo, Samantha

    2015-01-01

    Since October 2013, US Customs and Border Patrol has apprehended 15,979 families on the Southwest Border of the US. Daily, migrating women and children from Mexico and Central America that qualify for humanitarian parole are released from immigration detention to a humanitarian aid organization in Southern Arizona. After several days in detention facilities, these families arrive tired, hungry, dehydrated, and with minimal direction regarding their final destination, and adherence to the parameters of their parole. Project helping hands (PHHs) utilizes a network of volunteers to provide the women and children with food, water, clothing, hygiene products, hospitality, and legal orientation. The aim of this assessment was to document the experiences of families granted humanitarian parole through the lens of structural vulnerability. Here, we apply qualitative methods to elicit PHH lead volunteer perspectives regarding the migration experience of migrating families. Using inductive analysis, we found six major themes emerged from the qualitative data: reasons for leaving, experience on the journey, dehumanization in detention, family separation, vulnerability, and resiliency. These findings elucidate the different physical and psychological distresses that migrating families from Mexico and Central America experience before, during and after their arrival at the US–Mexico border. We posit that these distresses are a result of, or exacerbated by, structural vulnerability. Structural vulnerability has life-long health implications for a sub-population of young mothers and their children. The number of migrating families who have experienced traumatic events before and during their migration experience continues to expand and thus warrants consideration of mental health surveillance and intervention efforts for these families. More public health research is needed to better understand and combat the health challenges of this growing population. PMID:26157791

  5. Humanitarian accountability, bureaucracy, and self-regulation: the view from the archive.

    PubMed

    Roddy, Sarah; Strange, Julie-Marie; Taithe, Bertrand

    2015-10-01

    This paper contains a systematic exploration of local and national archives and sources relevant to charities and humanitarian fund appeals of the late Victorian and Edwardian eras (1870-1912) in Great Britain. It shows that the charitable world and humanitarian work share the same matrix and originate from the same roots, with considerable overlap between fundraising for domestic charity and overseas relief. These campaigns engaged in crucial self-regulatory processes very early on that involved concepts such as formal accountability and the close monitoring of delivery. Far from lagging behind in terms of formal practices of auditing and accounts, charities and humanitarian funds often were in the pioneering group as compared with mainstream businesses of the period. The charitable sector, notably through the Charity Organisation Society in cooperation with the press, developed and delivered accountability and monitoring, while the state and the Charity Commission played a negligible role in this process.

  6. THE LOSS OF MALAYSIA AIRLINES FLIGHT MH17: A FORENSIC AND HUMANITARIAN TASK.

    PubMed

    Ranson, David

    2015-06-01

    While forensic medical tasks are usually associated with supporting the criminal justice system, there are a range of forensic medical skills that can be brought to bear on addressing humanitarian activities. Disaster victim identification is a procedure that has achieved international standardisation through the work of a multinational Interpol Standing Committee. While part of a police organisation, it includes forensic pathologists, anthropologists, odontologists and molecular biologists who provide most of the specialist scientific input regarding identification that is integrated with police processes such as document examination and fingerprinting. The loss of Malaysian Airlines Flight MH17 represented a major activation of these procedures in an environment that had both humanitarian and forensic criminal investigation components. The information that is derived from the processes involved in disaster victim identification has a value that goes far beyond the determination of identity. It has an important humanitarian role in supporting the family and friends of the victims in their bereavement journey.

    Humanitarian medical programmes in the tropics have the opportunity to provide beacons of good practice. The use of modern drugs and diagnostics, a lack of bureaucracy, adequate budgets, motivated staff and well-functioning supply lines all contribute to the success of this approach. At a joint meeting of the Royal Society of Tropical Medicine, the London School of Hygiene and Tropical Medicine, Médecins Sans Frontières and Merlin, new data were presented on the outcomes of recent humanitarian programmes to control malaria (Ethiopia), human African trypanosomiasis (south Sudan), Lassa fever (Sierra Leone) and tuberculosis (Tomsk, former USSR).

    PubMed

    Gómez-Hernández, J Jaime

    2006-01-01

    It is difficult to define complexity in modeling. Complexity is often associated with uncertainty since modeling uncertainty is an intrinsically difficult task. However, modeling uncertainty does not require, necessarily, complex models, in the sense of a model requiring an unmanageable number of degrees of freedom to characterize the aquifer. The relationship between complexity, uncertainty, heterogeneity, and stochastic modeling is not simple. Aquifer models should be able to quantify the uncertainty of their predictions, which can be done using stochastic models that produce heterogeneous realizations of aquifer parameters. This is the type of complexity addressed in this article.

    Background Severe mental disorders are often neglected following a disaster. Based on Médecins Sans Frontières’ (MSF) experience of providing mental health (MH) care after the 2013 typhoon in the Philippines, we describe the monthly volume of MH activities and beneficiaries; characteristics of people seeking MH care; profile and outcomes of people with severe mental disorders; prescription of psychotropic medication; and factors facilitating the identification and management of individuals with severe mental disorders. Methods A retrospective review of programme data was carried out. Results In total, 172 persons sought MH care. Numbers peaked three months into MSF's intervention and decreased thereafter. Of 134 (78%) people with complete data, 37 (28%) had a severe mental disorder, often characterised by psychotic symptoms (n=24, 64%) and usually unrelated to the typhoon (n=32, 86%). Four people (11%) were discharged after successful treatment, two (5%) moved out of the area, 20 (54%) were referred for follow-up on cessation of MSF activities and 10 (27%) were lost-to-follow-up. Psychotropic treatment was prescribed for 33 (75%) people with mental disorders and for 11 with non-severe mental disorders. Conclusions This study illustrates how actors can play an important role in providing MH care for people with severe mental disorders in the aftermath of a disaster. PMID:27620925

    Barakat, Sultan; Deely, Seán; Zyck, Steven A

    2010-10-01

    While subject to increasing articulation and institutionalisation, stabilisation is a long-standing concept and practice that has consistently engaged with and, at times, conflicted with varied understandings of humanitarianism and humanitarian action. Reviewing selected historical experiences, including the Philippines (1898-1902), Algeria (1956-62), Vietnam (1967-75) and El Salvador (1980-92), this paper argues that contemporary models of stabilisation build on and repeat mistakes of the past, particularly the overt securitisation of aid and the perception that humanitarian and development actors are able to purchase security effectively. Where current stabilisation differs from its earlier incarnations, as in the introduction of the private sector and incorporation of humanitarian action into war-fighting strategies, the implications are shown to be troubling if not outright disastrous. T his examination of historical experience, which includes many failures and few, if any, successes, raises the likelihood that it is not solely the design or implementation of individual stability operations that require modification but perhaps the entire concept of stabilisation itself.

    Purpose. Congenital anomalies and injuries of the hand are often undertreated in low-middle income countries (LMICs). Humanitarian missions to LMICs are commonplace, but few exclusively hand surgery missions have been reported and none have attempted to demonstrate their cost-effectiveness. We present the first study evaluating the cost-effectiveness of a humanitarian hand surgery mission to Honduras as a method of reducing the global burden of surgically treatable disease. Methods. Data were collected from a hand surgery mission to San Pedro Sula, Honduras. Costs were estimated for local and volunteer services. The total burden of disease averted from patients receiving surgical reconstruction was derived using the previously described disability-adjusted life years (DALYs) system. Results. After adjusting for likelihood of disability associated with the diagnosis and likelihood of the surgery's success, DALYs averted totaled 104.6. The total cost for the mission was $45,779 (USD). The cost per DALY averted was calculated to be $437.80 (USD), which is significantly below the accepted threshold of two times the per capita gross national income of Honduras. Conclusions. This hand surgery humanitarian mission trip to Honduras was found to be cost-effective. This model and analysis should help in guiding healthcare professionals to organize future plastic surgery humanitarian missions.

    International nongovernmental organizations (NGOs) involved in humanitarian assistance employ millions of volunteers. One of the major challenges for the organizations is the high turnover rate among their personnel. Another is recruiting the right persons. As part of a series of studies investigating factors that affect the recruitment process and the success of assignment, this qualitative study examined health professionals' motivations for volunteering, their various concerns, and their expectations about themselves and the organizations for which they would work. The findings from focus group interviews with potential humanitarian volunteers were considered within the framework of Hertzberg's theory of motivations and Maslow's hierarchy of needs. The study has significant implications for personnel policy and practice in the humanitarian sector. Recruitment officers should have the self-actualized person, as described by Maslow, in mind when interviewing candidates. This perspective would make it easier for them to understand the candidates' thoughts and concerns and would lead to more effective interventions. Program officers should have satisfiers and dissatisfiers, as identified by Herzberg, in mind when planning programs. The probability that personnel will leave humanitarian work is lower if they perceive working conditions as good.

    Purpose. Congenital anomalies and injuries of the hand are often undertreated in low-middle income countries (LMICs). Humanitarian missions to LMICs are commonplace, but few exclusively hand surgery missions have been reported and none have attempted to demonstrate their cost-effectiveness. We present the first study evaluating the cost-effectiveness of a humanitarian hand surgery mission to Honduras as a method of reducing the global burden of surgically treatable disease. Methods. Data were collected from a hand surgery mission to San Pedro Sula, Honduras. Costs were estimated for local and volunteer services. The total burden of disease averted from patients receiving surgical reconstruction was derived using the previously described disability-adjusted life years (DALYs) system. Results. After adjusting for likelihood of disability associated with the diagnosis and likelihood of the surgery's success, DALYs averted totaled 104.6. The total cost for the mission was $45,779 (USD). The cost per DALY averted was calculated to be $437.80 (USD), which is significantly below the accepted threshold of two times the per capita gross national income of Honduras. Conclusions. This hand surgery humanitarian mission trip to Honduras was found to be cost-effective.

  6. Medical humanitarianism, human rights and political advocacy: the case of the Israeli Open Clinic.

    PubMed

    Gottlieb, Nora; Filc, Dani; Davidovitch, Nadav

    2012-03-01

    In the context of neo-liberal retrenchments humanitarian NGOs have become alternative healthcare providers that partially fill the vacuum left by the welfare state's withdrawal from the provision of services to migrants and other marginalized populations. In many cases they thus help to build legitimacy for the state's retreat from social responsibilities. Human rights organizations play an important role in advocating for migrants' rights, but in many cases they represent a legalistic and individualized conceptualization of the right to health that limits their claims for social justice. This paper analyzes the interactions and tensions between the discourses of medical humanitarianism, human rights and political advocacy using the example of an "Open Clinic" run by an Israeli human rights organization as a case-study: In 2007 dramatically increasing patient numbers provoked an intense internal debate concerning the proposal to temporarily close the "Open Clinic" in order to press the government to take action. Based on protocols from internal meetings and parliamentary hearings and in-depth interviews, we have analyzed divergent contextualizations of the Clinic's closure. These reflect conflicting notions regarding the Clinic's variegated spectrum of roles--humanitarian, political, legitimizing, symbolic, empowering and organizational--and underlying conceptualizations of migrants' "deservingness". Our case-study thus helps to illuminate NGOs' role in the realm of migrant healthcare and points out options for a possible fruitful relationship between the divergent paradigms of medical humanitarianism, human rights and political advocacy.

  8. A solution from hell: the United States and the rise of humanitarian interventionism, 1991-2003.

    PubMed

    Wertheim, Stephen

    2010-01-01

    This article traces the rise of humanitarian interventionist ideas in the US from 1991 to 2003. Until 1997, humanitarian intervention was a relatively limited affair, conceived ad hoc more than systematically, prioritized below multilateralism, aiming to relieve suffering without transforming foreign polities. For this reason, US leaders and citizens scarcely contemplated armed intervention in the Rwandan genocide of 1994: the US 'duty to stop genocide' was a norm still under development. It flourished only in the late 1990s, when humanitarian interventionism, like neoconservatism, became popular in the US establishment and enthusiastic in urging military invasion to remake societies. Now inaction in Rwanda looked outrageous. Stopping the genocide seemed, in retrospect, easily achieved by 5,000 troops, a projection that ignored serious obstacles. On the whole, humanitarian interventionists tended to understate difficulties of halting ethnic conflict, ignore challenges of postconflict reconstruction, discount constraints imposed by public opinion, and override multilateral procedures. These assumptions primed politicians and the public to regard the Iraq war of 2003 as virtuous at best and unworthy of strenuous dissent at worst. The normative commitment to stop mass killing outstripped US or international capabilities—a formula for dashed hopes and dangerous deployments that lives on in the 'responsibility to protect'.

    We have carried out research to determine the dynamics of failure in complex geomaterials, specifically focusing on the role of defects, damage and asperities in the catastrophic failure processes (now popularly termed “Black Swan events”). We have examined fracture branching and flow processes using models for invasion percolation, focusing particularly on the dynamics of bursts in the branching process. We have achieved a fundamental understanding of the dynamics of nucleation in complex geomaterials, specifically in the presence of inhomogeneous structures.

  10. Emerging patterns in the reconstruction of conflict-affected countries.

    PubMed

    Jacoby, Tim; James, Eric

    2010-01-01

    This paper introduces the five other contributions that make up this special edition of Disasters. It presents some background on the general issues that surround the reconstruction of conflict-affected countries, before going on to comment on some of the more prominent concerns that have emerged within the sphere of humanitarianism over the past decade or so. To contextualise the overall theme of this special edition, it then points to three areas of commonality among the five substantive papers-namely, issues of 'marketisation', 'politicisation', and 'securitisation'. These, this paper proposes, represent emerging patterns in the reconstruction of conflict-affected countries generally. The focus of this special edition thus has a broader resonance and, as such, it might be considered to be representative of wider geopolitical trends. It is, in sum, argued that these three patterns have combined to narrow the space in which humanitarian and reconstructive interventions into conflict-affected countries are organised and undertaken.

    2013-10-01

    Pediatricians regularly see emergencies in the office, or children that require transfer to an emergency department, or hospitalization. An office self-assessment is the first step in determining how to prepare for an emergency. The use of mock codes and skill drills make office personnel feel less anxious about medical emergencies. Emergency information forms provide valuable, quick information about complex patients for emergency medical services and other physicians caring for patients. Furthermore, disaster planning should be part of an office preparedness plan.

    Beginning October 2015, the Center for Medicare and Medicaid Services (CMS) will require medical providers to utilize the vastly expanded ICD-10-CM system. Despite wide availability of information and mapping tools for the next generation of the ICD classification system, some of the challenges associated with transition from ICD-9-CM to ICD-10-CM are not well understood. To quantify the challenges faced by emergency physicians, we analyzed a subset of a 2010 Illinois Medicaid database of emergency department ICD-9-CM codes, seeking to determine the accuracy of existing mapping tools in order to better prepare emergency physicians for the change to the expanded ICD-10-CM system. We found that 27% of 1,830 codes represented convoluted multidirectional mappings. We then analyzed the convoluted transitions and found 8% of total visit encounters (23% of the convoluted transitions) were clinically incorrect. The ambiguity and inaccuracy of these mappings may impact the work flow associated with the translation process and affect the potential mapping between ICD codes and CPT (Current Procedural Codes) codes, which determine physician reimbursement.

    Background International humanitarian aid workers providing care in emergencies are subjected to numerous chronic and traumatic stressors. Objectives To examine consequences of such experiences on aid workers' mental health and how the impact is influenced by moderating variables. Methodology We conducted a longitudinal study in a sample of international non-governmental organizations. Study outcomes included anxiety, depression, burnout, and life and job satisfaction. We performed bivariate regression analyses at three time points. We fitted generalized estimating equation multivariable regression models for the longitudinal analyses. Results Study participants from 19 NGOs were assessed at three time points: 212 participated at pre-deployment; 169 (80%) post-deployment; and 154 (73%) within 3–6 months after deployment. Prior to deployment, 12 (3.8%) participants reported anxiety symptoms, compared to 20 (11.8%) at post-deployment (p = 0·0027); 22 (10.4%) reported depression symptoms, compared to 33 (19.5%) at post-deployment (p = 0·0117) and 31 (20.1%) at follow-up (p = .00083). History of mental illness (adjusted odds ratio [AOR] 4.2; 95% confidence interval [CI] 1·45–12·50) contributed to an increased risk for anxiety. The experience of extraordinary stress was a contributor to increased risk for burnout depersonalization (AOR 1.5; 95% CI 1.17–1.83). Higher levels of chronic stress exposure during deployment were contributors to an increased risk for depression (AOR 1·1; 95% CI 1·02–1.20) comparing post- versus pre-deployment, and increased risk for burnout emotional exhaustion (AOR 1.1; 95% CI 1.04–1.19). Social support was associated with lower levels of depression (AOR 0·9; 95% CI 0·84–0·95), psychological distress (AOR = 0.9; [CI] 0.85–0.97), burnout lack of personal accomplishment (AOR 0·95; 95% CI 0·91–0·98), and greater life satisfaction (p = 0.0213).

    Enhancing situational awareness in real-time (RT) civil protection and emergency response scenarios requires the development of comprehensive monitoring concepts combining classical remote sensing disciplines with geospatial information science. In the VABENE++ project of the German Aerospace Center (DLR) monitoring tools are being developed by which innovative data acquisition approaches are combined with information extraction as well as the generation and dissemination of information products to a specific user. DLR's 3K and 4k camera system which allow for a RT acquisition and pre-processing of high resolution aerial imagery are applied in two application examples conducted with end users: a civil protection exercise with humanitarian relief organisations and a large open-air music festival in cooperation with a festival organising company. This study discusses how airborne remote sensing can significantly contribute to both, situational assessment and awareness, focussing on the downstream processes required for extracting information from imagery and for visualising and disseminating imagery in combination with other geospatial information. Valuable user feedback and impetus for further developments has been obtained from both applications, referring to innovations in thematic image analysis (supporting festival site management) and product dissemination (editable web services). Thus, this study emphasises the important role of user involvement in application-related research, i.e. by aligning it closer to user's requirements.

    PubMed

    De Cordier, Bruno

    2009-10-01

    This paper focuses on the emergence and modus operandi of Muslim faith-based aid organisations from the West, particularly those from the United Kingdom. Through case studies of Islamic Relief Worldwide and Muslim Hands, it examines the actual and potential added value generated by these humanitarian players in Muslim-majority contexts at times when aid actors from or associated with the West are being perceived by some as instrumental to the political agendas of Western powers, or are being confronted with the consequences thereof. The study analyses Muslim faith-based aid organisations' transnational networks, their implementing partnerships with local faith-based non-governmental organisations (NGOs), and their security position within and their access to insecure contexts, drawing on field examples and opinion from Central Asia, Iraq and Pakistan. It thereby argues that there is ground for an expansion of the role of Muslim aid actors, because of the existence of social and political realities in the field that cannot be always effectively tackled by the dominant international development approaches.

  17. Refugee flow or brain-drain? The humanitarian policy and post-Tiananmen mainland Chinese immigration to Canada.

    1997-03-01

    "The humanitarian policy that the Canadian government implemented in response to the 1989 Tiananmen Square crackdown changed a migration system primarily based on personal networks into a brain drain. Post-Tiananmen mainland Chinese immigrants (MCIs) were better educated than those arriving in Canada previously. Among the post-Tiananmen MCIs, those who landed under the policy were better educated than those landing in other categories. The analysis suggests that post-Tiananmen MCIs represented a brain-drain rather than a refugee flow, that the humanitarian policy implicitly contained ideological and human capital concerns in addition to humanitarian concerns, and that Canada benefited from the policy by obtaining human capital as well as satisfying its humanitarian obligations and ideological aspirations."

    2013-01-01

    Summary Debates on the subject of cultural complexity and its material manifestations are situated at the centre of research on prehistoric pastoralism in North Africa. Employing already published databases, this article integrates raw data from archaeological sites across the Sahara with ethnography to generate a framework of analysis in which changes in material culture can be interpreted. It attempts to establish a relationship between the analysis of human and cattle remains in order to study (a) the relations between modes of interment of animals and of humans, and social changes, and (b) the processes responsible for the appearance of a symbolism of power in the mid- and late Holocene funerary rituals. Their integration with landscape systems results in a conclusion of complex patterns of cultural diversity which question previous dismissals of early Saharan pastoral-is is as the progenitors of social complexity.

    2013-03-01

    Short-term predictions of potential impacts from accidental release of various radionuclides at nuclear power plants are acutely needed, especially after the Fukushima accident in Japan. An integrated modeling system that provides expert services to assess the consequences of accidental or intentional releases of radioactive materials to the atmosphere has received wide attention. These scenarios can be initiated either by accident due to human, software, or mechanical failures, or from intentional acts such as sabotage and radiological dispersal devices. Stringent action might be required just minutes after the occurrence of accidental or intentional release. To fulfill the basic functions of emergency preparedness and response systems, previous studies seldom consider the suitability of air pollutant dispersion models or the connectivity between source term, dispersion, and exposure assessment models in a holistic context for decision support. Therefore, the Gaussian plume and puff models, which are only suitable for illustrating neutral air pollutants in flat terrain conditional to limited meteorological situations, are frequently used to predict the impact from accidental release of industrial sources. In situations with complex terrain or special meteorological conditions, the proposing emergency response actions might be questionable and even intractable to decisionmakers responsible for maintaining public health and environmental quality. This study is a preliminary effort to integrate the source term, dispersion, and exposure assessment models into a Spatial Decision Support System (SDSS) to tackle the complex issues for short-term emergency response planning and risk assessment at nuclear power plants. Through a series model screening procedures, we found that the diagnostic (objective) wind field model with the aid of sufficient on-site meteorological monitoring data was the most applicable model to promptly address the trend of local wind field patterns

    Digital technology is increasingly used in humanitarian action and promises to improve the health and social well-being of populations affected by both acute and protracted crises. We set out to (1) review the current landscape of digital technologies used by humanitarian actors and affected populations, (2) examine their impact on health and well-being of affected populations, and (3) consider the opportunities for and challenges faced by users of these technologies. Through a systematic search of academic databases and reports, we identified 50 digital technologies used by humanitarian actors, and/or populations affected by crises. We organized them according to the stage of the humanitarian cycle that they were used in, and the health outcomes or determinants of health they affected. Digital technologies were found to facilitate communication, coordination, and collection and analysis of data, enabling timely responses in humanitarian contexts. A lack of evaluation of these technologies, a paternalistic approach to their development, and issues of privacy and equity constituted major challenges. We highlight the need to create a space for dialogue between technology designers and populations affected by humanitarian crises.

  2. Can we better use existing and emerging computing hardware to embed activity coefficient predictions in complex atmospheric aerosol models?

    2016-04-01

    To predict the evolving concentration, chemical composition and ability of aerosol particles to act as cloud droplets, we rely on numerical modeling. Mechanistic models attempt to account for the movement of compounds between the gaseous and condensed phases at a molecular level. This 'bottom up' approach is designed to increase our fundamental understanding. However, such models rely on predicting the properties of molecules and subsequent mixtures. For partitioning between the gaseous and condensed phases this includes: saturation vapour pressures; Henrys law coefficients; activity coefficients; diffusion coefficients and reaction rates. Current gas phase chemical mechanisms predict the existence of potentially millions of individual species. Within a dynamic ensemble model, this can often be used as justification for neglecting computationally expensive process descriptions. Indeed, on whether we can quantify the true sensitivity to uncertainties in molecular properties, even at the single aerosol particle level it has been impossible to embed fully coupled representations of process level knowledge with all possible compounds, typically relying on heavily parameterised descriptions. Relying on emerging numerical frameworks, and designed for the changing landscape of high-performance computing (HPC), in this study we show that comprehensive microphysical models from single particle to larger scales can be developed to encompass a complete state-of-the-art knowledge of aerosol chemical and process diversity. We focus specifically on the ability to capture activity coefficients in liquid solutions using the UNIFAC method, profiling traditional coding strategies and those that exploit emerging hardware.

  3. "Hypothesis for the Modern RNA World": A pervasive Non-coding RNA-Based Genetic Regulation is a Prerequisite for the Emergence of Multicellular Complexity

    NASA Astrophysics Data System (ADS)

    2011-12-01

    The transitions to multicellularity mark the most pivotal and distinctive events in life's history on Earth. Although several transitions to "simple" multicellularity (SM) have been recorded in both bacterial and eukaryotic clades, transitions to complex multicellularity (CM) have only happened a few times in eukaryotes. A large number of cell types (associated with large body size), increased energy consumption per gene expressed, and an increment of non-protein-coding DNA positively correlate with CM. These three factors can indeed be understood as the causes and consequences of the regulation of gene expression. Here, we discuss how a vast expansion of non-protein-coding RNA (ncRNAs) regulators rather than large numbers of novel protein regulators can easily contribute to the emergence of CM. We also propose that the evolutionary advantage of RNA-based gene regulation derives from the robustness of the RNA structure that makes it easy to combine genetic drift with functional exploration. We describe a model which aims to explain how the evolutionary dynamic of ncRNAs becomes dominated by the accessibility of advantageous mutations to innovate regulation in complex multicellular organisms. The information and models discussed here outline the hypothesis that pervasive ncRNA-based regulatory systems, only capable of being expanded and explored in higher eukaryotes, are prerequisite to complex multicellularity. Thereby, regulatory RNA molecules in Eukarya have allowed intensification of morphological complexity by stabilizing critical phenotypes and controlling developmental precision. Although the origin of RNA on early Earth is still controversial, it is becoming clear that once RNA emerged into a protocellular system, its relevance within the evolution of biological systems has been greater than we previously thought.

  4. Human Rights, Humanitarianism, and State Violence: Medical Documentation of Torture in Turkey.

    PubMed

    Can, Başak

    2016-09-01

    State authorities invested in developing official expert discourses and practices to deny torture in post-1980 coup d'état Turkey. Documentation of torture was therefore crucial for the incipient human rights movement there in the 1980s. Human rights physicians used their expertise not only to treat torture victims but also to document torture and eventually found the Human Rights Foundation of Turkey (HRFT) in 1990. Drawing on an ethnographic and archival research at the HRFT, this article examines the genealogy of anti-torture struggles in Turkey and argues that locally mediated intimacies and/or hostilities between victims of state violence, human rights physicians, and official forensics reveal the limitations of certain universal humanitarian and human rights principles. It also shows that locally mediated long-term humanitarian encounters around the question of political violence challenge forensic denial of violence and remake the legitimate levels of state violence.

    Between April and June 2014, International Orthodox Christian Charities (IOCC), an International NGO, and the Greek Orthodox Patriarchate of Antioch and All the East (GOPA) conducted a needs assessment of Syrians affected by the crisis with the objective of gaining a better understanding of humanitarian needs and assistance priorities. Findings suggest that interventions that increase access to non-food items, food, medication and education should be prioritized where cost was the primary barrier to accessing goods and services. Cash transfer programs and direct provision of material assistance should be considered, though the most appropriate assistance modality is likely to vary by sector, location and the preferences and prior experience of donors and implementing organizations. Renewed international commitment to funding humanitarian assistance efforts in Syria and neighboring countries where the burden of refugees is greatest is essential from both a human rights perspective and in terms of maintaining stability in the region.

  12. Perspectives from Ethiopia regarding U.S. military humanitarian assistance: how to build a better medical civil action project (MEDCAP).

    Assuming that budgetary constraints continue over the next several years, the U.S. military's overseas medical activities including medical civic action projects (MEDCAPs) and humanitarian assistance projects could comprise an increasing proportion of the contributions of U.S. government (USG) to improving global health. We have identified several issues with MEDCAPs in Ethiopia since 2009 that resulted in delays or project cancellations. These were mostly related to lack of a plan to develop sustainable capacities. Although there are many obvious medical needs for civilian populations in Ethiopia, the provision of sustainable development assistance involving these Ethiopian populations on behalf of the USG is a complex undertaking involving coordination with many partners and coordination with several other USG agencies. Military medical professionals planning MEDCAPs and other cooperative global health projects would benefit from consultation and close coordination with U.S. Centers for Disease Control and Prevention (CDC) and U.S. Agency of International Development (USAID) experts who are involved in supporting medium- and long-term health projects in Ethiopia. The establishment of durable military medical academic relationships and involvement of overseas military medical research units could also help promote sustainable projects and build robust professional relationships in global health.

  13. Trauma and humanitarian translation in Liberia: the tale of open mole.

    Abramowitz, Sharon Alane

    2010-06-01

    The focus of this paper is the intercultural process through which Open Mole and trauma-related mental illnesses are brought together in the postconflict mental health encounter. In this paper, I explore the historical dimension of this process by reviewing the history of Open Mole, and the ways in which it has been interpreted, acted on, and objectified by external observers over the last half-century. Moving into Liberia's recent war and postconflict period, I examine the process by which Open Mole is transformed from a culture-bound disorder into a local idiom of trauma, and how it has become a gateway diagnosis of PTSD-related mental illnesses, and consider how it is produced as an objectified experience of psychiatric disorder in clinical humanitarian contexts. By studying how Open Mole is transformed in the humanitarian encounter, I address the structure and teleology of the humanitarian encounter and challenge some of the foundational assumptions about cultural sensitivity and community-based mental health care in postconflict settings that are prevalent in scholarship and practice today.

    Disaster response demands a large workforce covering diverse professional sectors. Throughout this article, we illustrate the results of a systematic review of peer-reviewed studies to identify existing competency sets for disaster management and humanitarian assistance that would serve as guidance for the development of a common disaster curriculum. A systematic review of English-language articles was performed on PubMed, Google Scholar, Scopus, ERIC, and Cochrane Library. Studies were included if reporting competency domains, abilities, knowledge, skills, or attitudes for professionals involved disaster relief or humanitarian assistance. Exclusion criteria included abstracts, citations, case studies, and studies not dealing with disasters or humanitarian assistance. Thirty-eight papers were analyzed. Target audience was defined in all articles. Five references (13%) reported cross-sectorial competencies. Most of the articles (81.6%) were specific to health care. Eighteen (47%) papers included competencies for at least 2 different disciplines and 18 (47%) for different professional groups. Nursing was the most widely represented cadre. Eighteen papers (47%) defined competency domains and 36 (94%) reported list of competencies. Nineteen articles (50%) adopted consensus-building to define competencies, and 12 (31%) included competencies adapted to different professional responsibility levels. This systematic review revealed that the largest number of papers were mainly focused on the health care sector and presented a lack of agreement on the terminology used for competency-based definition.

    Pseudomonas aeruginosa move across surfaces by using multiple Type IV Pili (TFP), motorized appendages capable of force generation via linear extension/retraction cycles, to generate surface motions collectively known as twitching motility. Pseudomonas cells arrive at a surface with low levels of piliation and TFP activity, which both progressively increase as the cells sense the presence of a surface. At present, it is not clear how twitching motility emerges from these initial minimal conditions. Here, we build a simple model for TFP-driven surface motility without complications from viscous and solid friction on surfaces. We discover the unanticipated structural requirement that TFP motors need to have a minimal amount of effective angular rigidity in order for cells to perform the various classes of experimentally-observed motions. Moreover, a surprisingly small number of TFP are needed to recapitulate movement signatures associated with twitching: Two TFP can already produce movements reminiscent of recently observed slingshot type motion. Interestingly, jerky slingshot motions characteristic of twitching motility comprise the transition region between different types of observed crawling behavior in the dynamical phase diagram, such as self-trapped localized motion, 2-D diffusive exploration, and super-diffusive persistent motion.

    Multidisciplinary investigations at the Los Ajos archaeological mound complex in the wetlands of southeastern Uruguay challenge the traditional view that the La Plata basin was inhabited by simple groups of hunters and gatherers for much of the pre-Hispanic era. Here we report new archaeological, palaeoecological and botanical data indicating that during an increasingly drier mid-Holocene, at around 4,190 radiocarbon (14C) years before present (bp), Los Ajos became a permanent circular plaza village, and its inhabitants adopted the earliest cultivars known in southern South America. The architectural plan of Los Ajos during the following Ceramic Mound Period (around 3,000-500 14C yr bp) is similar to, but earlier than, settlement patterns demonstrated in Amazonia, revealing a new and independent architectural tradition for South America.

    The class of iron pnictides has been the focus of much attention for the discovery of superconductivity in the layered compounds LaOFeAs, CaFe2As2, and related ones; the phase diagrams of these pnictides remain still largely unexplored. Here, we report on the electronic and magnetic structure of the recently synthesized CaFe4As3 compound. This material, as opposed to the layered CaFe2As2, shows FeAs slabs parallel to the b-direction and approximately perpendicular to each other, defining tunnels filled by the Ca atoms. No sign of superconductivity was found in this compound. Instead, the system shows a complex ferromagnetic state at low temperature. DFT calculations performed on the refined crystal structure using the highly precise FLAPW methodootnotetextWimmer, Krakauer, Weinert, and Freeman, PRB, 24, 864 (1981) show a pronounced stabilization for the ferromagnetic state which is characterized by four distinct Fe sites with magnetic moments of between 1 μB and 2 μB. The influence of the local topology of the crystal structure on the the electronic and magnetic state is analyzed.

    Accurate prediction of complex traits based on whole-genome data is a computational problem of paramount importance, particularly to plant and animal breeders. However, the number of genetic markers is typically orders of magnitude larger than the number of samples (p > n), amongst other challenges. We assessed the effectiveness of a diverse set of state-of-the-art methods on publicly accessible real data. The most surprising finding was that approaches with feature selection performed better than others on average, in contrast to the expectation in the community that variable selection is mostly ineffective, i.e. that it does not improve accuracy of prediction, in spite of p > n. We observed superior performance despite a somewhat simplistic approach to variable selection, possibly suggesting an inherent robustness. This bodes well in general since the variable selection methods usually improve interpretability without loss of prediction power. Apart from identifying a set of benchmark data sets (including one simulated data), we also discuss the performance analysis for each data set in terms of the input characteristics.

  2. Agent-based spin model for financial markets on complex networks: Emergence of two-phase phenomena

    2008-09-01

    We study a microscopic model for financial markets on complex networks, motivated by the dynamics of agents and their structure of interaction. The model consists of interacting agents (spins) with local ferromagnetic coupling and global antiferromagnetic coupling. In order to incorporate more realistic situations, we also introduce an external field which changes in time. From numerical simulations, we find that the model shows two-phase phenomena. When the local ferromagnetic interaction is balanced with the global antiferromagnetic interaction, the resulting return distribution satisfies a power law having a single peak at zero values of return, which corresponds to the market equilibrium phase. On the other hand, if local ferromagnetic interaction is dominant, then the return distribution becomes double peaked at nonzero values of return, which characterizes the out-of-equilibrium phase. On random networks, the crossover between two phases comes from the competition between two different interactions. However, on scale-free networks, not only the competition between the different interactions but also the heterogeneity of underlying topology causes the two-phase phenomena. Possible relationships between the critical phenomena of spin system and the two-phase phenomena are discussed.

  3. The complex distribution of arterial system mechanical properties, pulsatile hemodynamics, and vascular stresses emerges from three simple adaptive rules.

    Arterial mechanical properties, pulsatile hemodynamic variables, and mechanical vascular stresses vary significantly throughout the systemic arterial system. Although the fundamental principles governing pulsatile hemodynamics in elastic arteries are widely accepted, a set of rules governing stress-induced adaptation of mechanical properties can only be indirectly inferred from experimental studies. Previously reported mathematical models have assumed mechanical properties adapt to achieve an assumed target stress "set point." Simultaneous prediction of the mechanical properties, hemodynamics, and stresses, however, requires that equilibrium stresses are not assumed a priori. Therefore, the purpose of this work was to use a "balance point" approach to identify the simplest set of universal adaptation rules that simultaneously predict observed mechanical properties, hemodynamics, and stresses throughout the human systemic arterial system. First, we employed a classical systemic arterial system model with 121 arterial segments and removed all parameter values except vessel lengths and peripheral resistances. We then assumed vessel radii increase with endothelial shear stress, wall thicknesses increase with circumferential wall stress, and material stiffnesses decrease with circumferential wall stress. Parameters characterizing adaptive responses were assumed to be identical in all arterial segments. Iteratively predicting local mechanical properties, hemodynamics, and stresses reproduced five trends observed when traversing away from the aortic root towards the periphery: decrease in lumen radii, wall thicknesses, and pulsatile flows and increase in wall stiffnesses and pulsatile pressures. The extraordinary complexity of the systemic arterial system can thus arise from independent adaptation of vessels to local stresses characterized by three simple adaptive rules.

    2010-01-01

    The essay centers of the efforts by the League of Nations to rescue women and children survivors of the 1915 Armenian Genocide. This rescue -- a seemingly unambiguous good -- was at once a constitutive act in drawing the boundaries of the international community, a key moment in the definition of humanitarianism, and a site of resistance to the colonial presence in the post-Ottoman Eastern Mediterranean. Drawing from a wide range of source materials in a number of languages, including Turkish, Armenian, and Arabic, the essay brings the intellectual and social context of humanitarianism in initiating societies together with the lived experience of humanitarianism in the places where the act took form. In so doing, it draws our attention to the proper place of the Eastern mediterranean, and its women and children, in the global history of humanitarianism. The prevailing narrative of the history of human rights places much of its emphasis on the post-World War II era, the international reaction to the Holocaust, and the founding of the United Nations. yet contemporary human rights thinking also took place within practices of humanitarianism in the interwar period, and is necessarily inseparable from the histories of refugees, colonialism, and the non-West.

  5. Use of low orbital satellite communications systems for humanitarian programs

    Communication and information exchange play a decisive role in progress and social development. However, in many parts of the world the communication infrastructure is inadequate and the capacity for on-line exchange of information may not exist. This is true of underdeveloped countries, remote and relatively inaccessible regions, sites of natural disasters, and of all cases where the resources needed to create complex communication systems are limited. The creation of an inexpensive space communications system to service such areas is therefore a high priority task. In addition to a relatively low-cost space segment, an inexpensive space communications systems requires a large number of ground terminals, which must be relatively inexpensive, energy efficient (using power generated by storage batteries, or solar arrays, etc.), small in size, and must not require highly expert maintenance. The ground terminals must be portable, and readily deployable. Communications satellites in geostationary orbit at altitudes of about 36,000 km are very expensive and require complex and expensive ground stations and launch vehicles. Given current technology, it is categorically impossible to develop inexpensive satellite systems with portable ground terminals using such satellites. To solve the problem of developing an inexpensive satellite communications system that can operate with relatively small ground stations, including portable terminals, we propose to use a system with satellites in low Earth orbit, at an altitude of 900-1500 km. Because low orbital satellites are much closer to the Earth than geostationary ones and require vastly less energy expenditure by the satellite and ground terminals for transmission of messages, a system using them is relatively inexpensive. Such a system could use portable ground terminals no more complex than ordinary mobile police radios.

    The 21st century has borne witness to catastrophic natural and human-induced tragedies. These disasters necessitate humanitarian responses; however, the individual and collective bases of support are not well understood. Drawing on Duncan's motivational model of collective action, we focus on how individual differences position a person to adopt group memberships and develop a "group consciousness" that provides the basis for humanitarian action. Longitudinal mediation analyses involving supporters of international humanitarian action (N = 384) sampled annually for 3 years provided support for the hypothesized model, with some twists. The results revealed that within time point, a set of individual differences (together, the "pro-social orientation") promoted a humanitarian group consciousness that, in turn, facilitated collective action. However, longitudinally, there was evidence that a more general pro-social orientation undermined subsequent identification with, and engagement in, the humanitarian cause. Results are discussed in terms of understanding the interplay between individual and group in collective actions.

  8. Employing moderate resolution sensors in human rights and international humanitarian law monitoring

    NASA Astrophysics Data System (ADS)

    Marx, Andrew J.

    Organizations concerned with human rights are increasingly using remote sensing as a tool to improve their detection of human rights and international humanitarian law violations. However, as these organizations have transitioned to human rights monitoring campaigns conducted over large regions and extended periods of time, current methods of using fine- resolution sensors and manpower-intensive analyses have become cost- prohibitive. To support the continued growth of remote sensing in human rights and international humanitarian law monitoring campaigns, this study researches how moderate resolution land observatories can provide complementary data to operational human rights monitoring efforts. This study demonstrates the capacity of moderate resolutions to provide data to monitoring efforts by developing an approach that uses Landsat Enhanced Thematic Mapper Plus (ETM+) as part of a system for the detection of village destruction in Darfur, Sudan. Village destruction is an indicator of a human rights or international humanitarian law violations in Darfur during the 2004 study period. This analysis approach capitalizes on Landsat's historical archive and systematic observations by constructing a historic spectral baseline for each village in the study area that supports automated detection of a potentially destroyed village with each new overpass of the sensor. Using Landsat's near-infrared band, the approach demonstrates high levels of accuracy when compared with a U.S. government database documenting destroyed villages. This approach is then applied to the Darfur conflict from 2002 to 2008, providing new data on when and where villages were destroyed in this widespread and long-lasting conflict. This application to the duration of a real-world conflict illustrates the abilities and shortcomings of moderate resolution sensors in human rights monitoring efforts. This study demonstrates that moderate resolution satellites have the capacity to contribute

    The French contribution to global public health over the past two centuries has been marked by a fundamental tension between two approaches: State-provided universal free health care and what we propose to call State humanitarian verticalism. Both approaches have historical roots in French colonialism and have led to successes and failures that continue until the present day. In this paper, the second in The Lancet's Series on France, we look at how this tension has evolved. During the French colonial period (1890s to 1950s), the Indigenous Medical Assistance structure was supposed to bring metropolitan France's model of universal and free public health care to the colonies, and French State imperial humanitarianism crystallised in vertical programmes inspired by Louis Pasteur, while vying with early private humanitarian activism in health represented by Albert Schweitzer. From decolonisation to the end of the Cold War (1960-99), French assistance to newly independent states was affected by sans frontièrisme, Health for All, and the AIDS pandemic. Since 2000, France has had an active role in development of global health initiatives and favoured multilateral action for health assistance. Today, with adoption of the 2030 Sustainable Development Goals and the challenges of non-communicable diseases, economic inequality, and climate change, French international health assistance needs new direction. In the context of current debate over global health as a universal goal, understanding and acknowledging France's history could help strengthen advocacy in favour of universal health coverage and contribute to advancing global equity through income redistribution, from healthy populations to people who are sick and from wealthy individuals to those who are poor.

  10. Evidence on the Effectiveness of Water, Sanitation, and Hygiene (WASH) Interventions on Health Outcomes in Humanitarian Crises: A Systematic Review

    2015-01-01

    Background Water, sanitation, and hygiene (WASH) interventions are amongst the most crucial in humanitarian crises, although the impact of the different WASH interventions on health outcomes remains unclear. Aim To examine the quantity and quality of evidence on WASH interventions on health outcomes in humanitarian crises, as well as evaluate current evidence on their effectiveness against health outcomes in these contexts. Methods A systematic literature review was conducted of primary and grey quantitative literature on WASH interventions measured against health outcomes in humanitarian crises occurring from 1980–2014. Populations of interest were those in resident in humanitarian settings, with a focus on acute crisis and early recovery stages of humanitarian crises in low and middle-income countries. Interventions of interest were WASH-related, while outcomes of interest were health-related. Study quality was assessed via STROBE/CONSORT criteria. Results were analyzed descriptively, and PRISMA reporting was followed. Results Of 3963 studies initially retrieved, only 6 published studies measured a statistically significant change in health outcome as a result of a WASH intervention. All 6 studies employed point-of-use (POU) water quality interventions, with 50% using safe water storage (SWS) and 35% using household water treatment (HWT). All 6 studies used self-reported diarrhea outcomes, 2 studies also reported laboratory confirmed outcomes, and 2 studies reported health treatment outcomes (e.g. clinical admissions). 1 study measured WASH intervention success in relation to both health and water quality outcomes; 1 study recorded uptake (use of soap) as well as health outcomes. 2 studies were unblinded randomized-controlled trials, while 4 were uncontrolled longitudinal studies. 2 studies were graded as providing high quality evidence; 3 studies provided moderate and 1 study low quality evidence. Conclusion The current evidence base on the impact of WASH

  11. Evaluations of reproductive health programs in humanitarian settings: a systematic review

    PubMed Central

    2015-01-01

    Provision of reproductive health (RH) services is a minimum standard of health care in humanitarian settings; however access to these services is often limited. This systematic review, one component of a global evaluation of RH in humanitarian settings, sought to explore the evidence regarding RH services provided in humanitarian settings and to determine if programs are being evaluated. In addition, the review explored which RH services receive more attention based on program evaluations and descriptive data. Peer-reviewed papers published between 2004 and 2013 were identified via the Ovid MEDLINE database, followed by a PubMed search. Papers on quantitative evaluations of RH programs, including experimental and non-experimental designs that reported outcome data, implemented in conflict and natural disaster settings, were included. Of 5,669 papers identified in the initial search, 36 papers describing 30 programs met inclusion criteria. Twenty-five papers described programs in sub-Saharan Africa, six in Asia, two in Haiti and three reported data from multiple countries. Some RH technical areas were better represented than others: seven papers reported on maternal and newborn health (including two that also covered family planning), six on family planning, three on sexual violence, 20 on HIV and other sexually transmitted infections and two on general RH topics. In comparison to the program evaluation papers identified, three times as many papers were found that reported RH descriptive or prevalence data in humanitarian settings. While data demonstrating the magnitude of the problem are crucial and were previously lacking, the need for RH services and for evaluations to measure their effectiveness is clear. Program evaluation and implementation science should be incorporated into more programs to determine the best ways to serve the RH needs of people affected by conflict or natural disaster. Standard program design should include rigorous program evaluation, and

    Post-burn contractures account for up to 50% of the workload of a plastic surgery team volunteering in developing nations. Best possible outcome most likely requires extensive surgery. However, extensive approaches such as microsurgery are generally discouraged in these settings. We report two successful cases of severe hand contractures reconstructed with free flaps on a surgical mission in Kenya. Microsurgery can be safely performed in the humanitarian setting by an integration of: personal skills; technical means; education of local personnel; follow-up services; and an effective network for communication.

  13. Militarized humanitarianism meets carceral feminism: the politics of sex, rights, and freedom in contemporary antitrafficking campaigns.

    PubMed

    Bernstein, Elizabeth

    2010-01-01

    Over the past decade, abolitionist feminist and evangelical Christian activists have directed increasing attention toward the “traffic in women” as a dangerous manifestation of global gender inequalities. Despite renowned disagreements around the politics of sex and gender, these groups have come together to advocate for harsher penalties against traffickers, prostitutes’ customers, and nations deemed to be taking insufficient steps to stem the flow of trafficked women. In this essay, I argue that what has served to unite this coalition of "strange bedfellows" is not simply an underlying commitment to conservative ideals of sexuality, as previous commentators have offered, but an equally significant commitment to carceral paradigms of justice and to militarized humanitarianism as the preeminent mode of engagement by the state. I draw upon my ongoing ethnographic research with feminist and evangelical antitrafficking movement leaders to argue that the alliance that has been so efficacious in framing contemporary antitrafficking politics is the product of two historically unique and intersecting trends: a rightward shift on the part of many mainstream feminists and other secular liberals away from a redistributive model of justice and toward a politics of incarceration, coincident with a leftward sweep on the part of many younger evangelicals toward a globally oriented social justice theology. In the final section of this essay, I consider the resilience of these trends given a newly installed and more progressive Obama administration, positing that they are likely to continue even as the terrain of militarized humanitarian action shifts in accordance with new sets of geopolitical interests.

  14. Fluid technologies: The Bush Pump, the LifeStraw and microworlds of humanitarian design.

    PubMed

    Redfield, Peter

    2016-04-01

    Over the past decade, many ingenious, small-scale gadgets have appeared in response to problems of disaster and extreme poverty. Focusing on the LifeStraw, a water filtration device invented by the company Vestergaard Frandsen, I situate this wave of humanitarian design relative to Marianne de Laet and Annemarie Mol's classic article on the Zimbabwe Bush Pump. The LifeStraw shares the Bush Pump's principle of technical minimalism, as well as its ethical desire to improve the lives of communities. Unlike the pump, however, the straw defines itself through rather than against market logic, accepting the premise that one can 'do well while doing good'. Moreover, it does not share the assumed framework of de Laet and Mol's Zimbabwean socio-technical landscape: a postcolonial state happily en route to national self-definition. Nonetheless, it clearly embodies moral affect, if in the idiom of humanitarian concern rather than development. My aim is to open up three interrelated lines of inquiry for discussion. First, I consider aspects of a postcolonial condition at the micro-level of immediate needs, including assumptions about nation-state politics and markets. Second, I emphasize science and technology in the form of infrastructure, the material frontline of norms. Third, I return reflexively to love, and the complicated allure of engagement in academic work.

    OBJECTIVE: To establish the context in which maternal psychosocial well-being is understood in war-affected settings in Eritrea. METHOD: Pretested and validated participatory methods and tools of investigation and analysis were employed to allow participants to engage in processes of qualitative data collection, on-site analysis, and interpretation. FINDINGS: Maternal psychosocial well-being in Eritrea is maintained primarily by traditional systems of social support that are mostly outside the domain of statutory primary care. Traditional birth attendants provide a vital link between the two. Formal training and regular supplies of sterile delivery kits appear to be worthwhile options for health policy and practice in the face of the post-conflict challenges of ruined infrastructure and an overstretched and/or ill-mannered workforce in the maternity health service. CONCLUSION: Methodological advances in health research and the dearth of data on maternal psychosocial well-being in complex emergency settings call for scholars and practitioners to collaborate in creative searches for sound evidence on which to base maternity, mental health and social care policy and practice. Participatory methods facilitate the meaningful engagement of key stakeholders and enhance data quality, reliability and usability. PMID:12856054

    Introduction Operational stress describes individual behavior in response to the occupational demands and tempo of a mission. The stress response of military personnel involved in combat and peace-keeping missions has been well-described. The spectrum of effect on medical professionals and support staff providing humanitarian assistance, however, is less well delineated. Research to date concentrates mainly on shore-based humanitarian missions. Problem The goal of the current study was to document the pattern of operational stress, describe factors responsible for it, and the extent to which these factors impact job performance in military and civilian participants of Continuing Promise 2011 (CP11), a ship-based humanitarian medical mission.

  1. Brachypodium as an emerging model for cereal–pathogen interactions

    Background Cereal diseases cause tens of billions of dollars of losses annually and have devastating humanitarian consequences in the developing world. Increased understanding of the molecular basis of cereal host–pathogen interactions should facilitate development of novel resistance strategies. However, achieving this in most cereals can be challenging due to large and complex genomes, long generation times and large plant size, as well as quarantine and intellectual property issues that may constrain the development and use of community resources. Brachypodium distachyon (brachypodium) with its small, diploid and sequenced genome, short generation time, high transformability and rapidly expanding community resources is emerging as a tractable cereal model. Scope Recent research reviewed here has demonstrated that brachypodium is either susceptible or partially susceptible to many of the major cereal pathogens. Thus, the study of brachypodium–pathogen interactions appears to hold great potential to improve understanding of cereal disease resistance, and to guide approaches to enhance this resistance. This paper reviews brachypodium experimental pathosystems for the study of fungal, bacterial and viral cereal pathogens; the current status of the use of brachypodium for functional analysis of cereal disease resistance; and comparative genomic approaches undertaken using brachypodium to assist characterization of cereal resistance genes. Additionally, it explores future prospects for brachypodium as a model to study cereal–pathogen interactions. Conclusions The study of brachypodium–pathogen interactions appears to be a productive strategy for understanding mechanisms of disease resistance in cereal species. Knowledge obtained from this model interaction has strong potential to be exploited for crop improvement. PMID:25808446

  2. How do emergency managers use social media platforms?

    PubMed

    Bennett, DeeDee M

    2014-01-01

    Social media platforms are increasingly becoming a useful tool for victims, humanitarians, volunteers, and the general public to communicate during disasters. Research has shown that there are multiple advantages to using social media and the applicability of these platforms crosses several different types of disasters (human-caused, natural, and terrorist) here in the United States and abroad. However, some emergency management agencies have been reluctant to use social media as one of their many communications tools. In this study, the usefulness of social media for emergency management was examined over a 30-day period following a series of tornadoes. Using an observational approach, the public posts disseminated from an emergency management agency were analyzed to determine how two social media platforms were used. The findings show how emergency management agencies could leverage the connectedness of social media to reach victims and make unlikely partnerships.

  3. El Niño-Flood Predictability for Early Humanitarian Action

    2016-04-01

    El Niño Southern Oscillation (ENSO), a mode of variability which sees anomalously high or low sea surface temperatures in the Pacific, is known to have a significant impact on both hydrology and meteorology across the globe. One significant influence is that of El Niño, the warm phase of ENSO, on flooding in the Piura region of Peru. The anticipation and forecasting of floods is crucial for flood preparedness, and the link between El Niño and flooding in Peru, alongside the predictive skill of El Niño up to seasons ahead, may provide an early indication of upcoming severe flood events. The Global Flood Awareness System (GloFAS) has been used to create the first 110-year global reanalysis dataset of river discharge, using the ECMWF ERA-20C atmospheric reanalysis. These datasets are being used to analyse the predictability of flood events in Peru in relation to ENSO, using both hydrological and meteorological approaches; with the aim of providing early indicators of potential flood events and thresholds for early humanitarian action in the region. In particular, this research also aims to determine the causes of the most extreme flood events, such as those observed in 1982/83 and 1997/98, through investigation of the changes in atmospheric circulation during these events. Forecast-based Financing (FbF) is an initiative of the German Red Cross, for disbursing humanitarian funding as soon as a forecast threshold is crossed, prior to a severe event. Collaboration with the Peruvian Red Cross and SENAHMI during 2015 led to the use of such research to define thresholds for action in Piura during an El Niño, as part of an FbF pilot study. We will present here the link between El Niño and flooding, with a focus on the Piura region of Peru, and how this El Niño-flood predictability may be used for flood preparedness and early humanitarian action in regions across the globe.

  7. Success in Kashmir: a positive trend in civil-military integration during humanitarian assistance operations.

    PubMed

    Thompson, Wiley C

    2010-01-01

    The modern cast of disaster relief actors includes host nations, non-governmental organisations, private volunteer organisations, military organisations and others. Each group, civilian or military, has valuable skills and experiences critical to disaster relief work. The goal of this paper is to supplement the study of civil-military relief efforts with contemporary anecdotal experience. The paper examines the interaction between US military forces and other disaster relief actors during the 2005 Kashmir earthquake relief effort. The author uses direct observations made while working in Pakistan to contrast the relationships and activities from that effort with other accounts in prevailing scholarly disaster literature and military doctrine. Finally, this paper suggests that the Kashmir model of integration, coordination and transparency of intent creates a framework in which future humanitarian assistance operations could be successfully executed. Recommendations to improve civil-military interaction in future relief efforts will also be addressed.

    Short-term humanitarian medical volunteerism has grown significantly among both clinicians and trainees over the past several years. Increasingly, both volunteers and their respective institutions have faced important challenges in regard to medical ethics and professional codes that should not be overlooked. We explore these potential concerns and their risk factors in three categories: ethical responsibilities in patient care, professional responsibility to communities and populations, and institutional responsibilities towards trainees. We discuss factors increasing the risk of harm to patients and communities, including inadequate preparation, the use of advanced technology and the translation of Western medicine, issues with clinical epidemiology and test utility, difficulties with the principles of justice and clinical justice, the lack of population-based medicine, sociopolitical effects of foreign aid, volunteer stress management, and need for sufficient trainee supervision. We review existing resources and offer suggestions for future skill-based training, organisational responsibilities, and ethical preparation.

    2016-08-01

    We present a common framework for Bayesian emulation methodologies for multivariate output simulators, or computer models, that employ either parametric linear models or non-parametric Gaussian processes. Novel diagnostics suitable for multivariate covariance separable emulators are developed and techniques to improve the adequacy of an emulator are discussed and implemented. A variety of emulators are compared for a humanitarian relief simulator, modelling aid missions to Sicily after a volcanic eruption and earthquake, and a sensitivity analysis is conducted to determine the sensitivity of the simulator output to changes in the input variables. The results from parametric and non-parametric emulators are compared in terms of prediction accuracy, uncertainty quantification and scientific interpretability.

  10. One health and force health protection during foreign humanitarian assistance operations: 2010 Pakistan flood relief.

    PubMed

    Burke, Ronald L

    2013-01-01

    Restrictions on the number of troops that could enter Pakistan in support of the 2010 flood relief efforts limited the type and number of deployed medical personnel. Although this created the potential for mission gaps, the assigned personnel were able to perform additional functions beyond those normally associated with their particular health specialty to help close these gaps, which was largely made possible due to prior cross-training and predeployment refresher training. Given the rapid and unpredictable nature of disaster response, future foreign humanitarian assistance operations may face similar issues with assigned personnel. Promotion of the One Health concept through instruction and training will help to increase awareness among US Army Medical Department personnel about the roles and functions of health specialties, facilitate the identification of critical gaps during deployments, and provide personnel with the knowledge and skills needed to address them.

  11. When "humanitarianism" becomes "development": the politics of international aid in Syria's Palestinian refugee camps.

    PubMed

    Gabiam, Nell

    2012-01-01

    In recent years, the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) has attempted to go beyond its role as a provider of relief and basic services in Palestinian refugee camps and emphasize its role as a development agency. In this article, I focus on the Neirab Rehabilitation Project, an UNRWA-sponsored development project taking place in the Palestinian refugee camps of Ein el Tal and Neirab in northern Syria. I argue that UNRWA's role as a relief-centered humanitarian organization highlights the everyday suffering of Palestinian refugees, suffering that has become embedded in refugees’ political claims. I show that UNRWA's emphasis on “development” in the refugee camps is forcing Palestinian refugees in Ein el Tal and Neirab to reassess the political narrative through which they have understood their relationship with UNRWA.

    Background: Our objective was to identify published models of coordination between entities funding or delivering health services in humanitarian crises, whether the coordination took place during or after the crises. Methods: We included reports describing models of coordination in sufficient detail to allow reproducibility. We also included reports describing implementation of identified models, as case studies. We searched Medline, PubMed, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, PsycINFO, and the WHO Global Health Library. We also searched websites of relevant organizations. We followed standard systematic review methodology. Results: Our search captured 14,309 citations. The screening process identified 34 eligible papers describing five models of coordination of delivering health services: the “Cluster Approach” (with 16 case studies), the 4Ws “Who is Where, When, doing What” mapping tool (with four case studies), the “Sphere Project” (with two case studies), the “5x5” model (with one case study), and the “model of information coordination” (with one case study). The 4Ws and the 5x5 focus on coordination of services for mental health, the remaining models do not focus on a specific health topic. The Cluster approach appears to be the most widely used. One case study was a mixed implementation of the Cluster approach and the Sphere model. We identified no model of coordination for funding of health service. Conclusion: This systematic review identified five proposed coordination models that have been implemented by entities funding or delivering health service in humanitarian crises. There is a need to compare the effect of these different models on outcomes such as availability of and access to health services. PMID:27617167

    Olin, Emma; von Schreeb, Johan

    2014-01-01

    Background: International humanitarian assistance is essential for disaster-affected populations, particularly in resource scarce settings. To target such assistance, needs assessments are required. According to internationally endorsed principles, donor governments should provide funding for humanitarian assistance based on need. Aim: The aim of this study is to explore a major donor’s use of needs assessment data in decision-making for allocations of funds for health-related humanitarian assistance contributions. Setting: This is a case study of the Swedish International Development Cooperation Agency (Sida), a major and respected international donor of humanitarian assistance. Methods: To explore Sida’s use of needs assessment data in practice for needs-based allocations, we reviewed all decision documents and assessment memoranda for humanitarian assistance contributions for 2012 using content analysis; this was followed by interviews with key personnel at Sida. Results: Our document analysis found that needs assessment data was not systematically included in Sida’s assessment memoranda and decision documents. In the interviews, we observed various descriptions of the concept of needs assessments, the importance of contextual influences as well as previous collaborations with implementing humanitarian assistance organizations. Our findings indicate that policies guiding funding decisions on humanitarian assistance need to be matched with available needs assessment data and that terminologies and concepts have to be clearly defined. Conclusion: Based on the document analysis and the interviews, it is unclear how well Sida used needs assessment data for decisions to allocate funds. However, although our observations show that needs assessments are seldom used in decision making, Sida’s use of needs assessments has improved compared to a previous study. To improve project funds allocations based on needs assessment data, it will be critical to develop

  16. Achievements and bottlenecks in humanitarian demining EU-funded research: final results from the EC DELVE project

    2008-04-01

    The EC DELVE Support Action project has analyzed the bottlenecks in the transfer of Humanitarian Demining (HD) technology from technology development to the use in the field, and drawn some lessons learned, basing itself on the assessment of the European Humanitarian Demining Research and Technology Development (RTD) situation from early 1990 until 2006. The situation at the European level was analyzed with emphasis on activities sponsored by the European Commission (EC). This was also done for four European countries and Japan, with emphasis on national activities. The developments in HD during the last 10 years underline the fact that in a number of cases demining related developments have been terminated or at least put on hold. The study also showed that the funding provided by the EC under the Framework Program for RTD has led directly to the creation of an extensive portfolio of Humanitarian Demining technology development projects. The latter provided a range of research and supporting measures addressing the critical issues identified as a result of the regulatory policies developed in the field of Humanitarian Demining over the last ten years. However, the range of instruments available to the EC to finance the necessary research and development were limited, to pre-competitive research. The EC had no tools or programs to directly fund actual product development. As a first consequence, the EC funding program for development of technology for Humanitarian Demining unfortunately proved to be largely unsuitable for the small-scale development needed in a field where there is only a very limited market. As a second consequence, most of the research has been demonstrator-oriented. Moreover, the timeframe for RTD in Humanitarian Demining has not been sufficiently synchronized with the timeframe of the EC policies and regulations. The separation of the Mine Action and RTD funding streams in the EC did also negatively affect the take-up of new technologies. As a

    This article describes the dissemination and knowledge transfer activities of Evidence Aid, which was established after the Indian Ocean tsunami of December 2004 to provide a single source of evidence that would help people make well-informed decisions when preparing for and responding to disasters. Evidence Aid has a dedicated website (www.EvidenceAid.org) to provide access to more than 160 systematic reviews and several other documents relevant to people working on disaster risk reduction, planning, response, recovery, rehabilitation, and resilience. It combines this with a social media presence and Special Collections that bundle together related Cochrane Reviews (www.TheCochraneLibrary.com). The aim is to make it easier for users who need this evidence and don't have time to browse through multiple documents and distill them before making their decisions. Evidence Aid will continue to identify and share resources and knowledge with those who most need it at the time that they need it most. It is working with several partners to identify relevant Cochrane and non-Cochrane systematic reviews and is engaging with users who, by sharing their information and their knowledge needs, will allow Evidence Aid to target its efforts to these priority areas.

  19. Minimum Initial Service Package (MISP) for reproductive health during emergencies: time for a new paradigm?

    PubMed

    Onyango, Monica Adhiambo; Hixson, Bretta Lynne; McNally, Siobhan

    2013-01-01

    Reproductive health (RH) has historically received low priority in the hierarchy of humanitarian response. Awareness of RH needs in emergencies began in the mid-1990s and led to the formation of the Inter-Agency Working Group (IAWG) for RH. Subsequently, the Minimum Initial Service Package (MISP), a set of guidelines for RH service delivery in crisis settings, was created. The objectives of the MISP are to facilitate the coordination of RH services, prevent and manage the consequences of sexual violence, reduce HIV transmission, minimize maternal and neonatal morbidity and mortality, and plan for comprehensive RH services in the post-crisis phase. Available documentation on MISP implementation is minimal, and reveals mixed success. Challenges include low MISP awareness, inadequate RH training among humanitarian actors, logistical difficulties and poor coordination. Continued emphasis on advocacy and capacity building, a stronger focus on logistics and coordination and a greater commitment to monitoring and evaluation are essential for improving the MISP's effectiveness in the field.

  20. Incidence, risk factors and clinical epidemiology of melioidosis: a complex socio-ecological emerging infectious disease in the Alor Setar region of Kedah, Malaysia

    PubMed Central

    2010-01-01

    Background Melioidosis, a severe and fatal infectious disease caused by Burkholderia pseudomallei, is believed to an emerging global threat. However, data on the natural history, risk factors, and geographic epidemiology of the disease are still limited. Methods We undertook a retrospective analysis of 145 confirmed cases extracted from a hospital-based Melioidosis Registry set up from 2005 in Hospital Sultanah Bahiyah, Alor Setar, Kedah state, Malaysia, in order to provide a first description of the contemporary incidence, risk factors, and clinical epidemiology of the disease in this putatively high risk region of the country. Results The incidence of melioidosis in Alor Setar is remarkably high at 16.35 per 100,000 population per year. The mean age of patients was 50.40 years, with infection varying nonlinearly with age. Males (75.2%; P < 0.0001) predominated and the majority of cases were Malays (88.9%). The overall, crude mortality rate among the study patients was 33.8%. The proportions of cases and deaths were significantly greater among patients involved in farming, forestry and fishing and the unemployed (χ2 = 30.57, P < 0.0001). A majority of cases (62.75%) were culture positive, with mortality in these patients being 45.05%. A large proportion (83.0%) of culture positives was also bacteremic. Pneumonia accounted for 42.06% of primary diagnoses followed in importance by soft tissue abscess. In patients with pneumonia and who were culture positive, the mortality rate was as high as 65.00%. Diabetes mellitus constituted the major underlying risk factor for developing and dying from melioidosis, occurring in 57% of all diagnosed cases. The age distribution of diabetes paralleled that of melioidosis cases. There were linear associations between cases and deaths with monthly rainfall. Conclusions Melioidosis represents a complex socio-ecological public health problem in Kedah, being strongly related with age, occupation, rainfall and predisposing chronic

    Changes in the molecular epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) continue to be reported. This study was carried out to characterize MRSA isolates in Saudi Arabia. MRSA isolates causing nosocomial infections (n = 117) obtained from 2009-2015 at a tertiary-care facility in Riyadh, Saudi Arabia, were studied. Molecular characterization of isolates was carried out using the StaphyType DNA microarray (Alere Technologies, Jena, Germany). Fourteen clonal complexes (CC) were identified, with the most common being CC80 (n = 35), CC6 (n = 15), CC5 (n = 13) and CC22 (n = 12). With the exception of nine ST239 MRSA-III isolates, all others were of community-associated MRSA lineages. The following strains are identified for the first time in Saudi Arabia: ST8-MRSA-IV [PVL(+)/ACME(+)], USA300 (n = 1); ST72-MRSA-IV USA700 (n = 1); CC5-MRSA-IV, [PVL(+)/edinA(+)], WA MRSA-121 (n = 1); CC5-MRSA-V+SCCfus, WA MRSA-14/109 (n = 2), CC97-MRSA-IV, WA MRSA-54/63; CC2250/2277-MRSA-IV and WA MRSA-114. CC15-MRSA (n = 3) was identified for the first time in clinical infection in Saudi Arabia. None of the isolates harboured vancomycin resistance genes, while genes for resistance to mupirocin and quaternary ammonium compounds were found in one and nine isolates respectively. Fifty-seven isolates (48.7%) were positive for Panton-Valentine leukocidin genes. While the staphylokinase (sak) and staphylococcal complement inhibitor (scn) genes were present in over 95% of the isolates, only 37.6% had the chemotaxis-inhibiting protein (chp) gene. Increasing occurrence of community-acquired MRSA lineages plus emergence of pandemic and rare MRSA strains is occurring in our setting. Strict infection control practices are important to limit the dissemination of these MRSA strains.

    In 2007, the United States Navy Ship (USNS) COMFORT (T-AH 20), a full-capability medical treatment facility, departed for Partnership for the Americas, her first large-scale humanitarian civic assistance (HCA) mission. Analysis of operational data describes surgical resource utilization. Lessons from previous military humanitarian assistance operations were helpful when placed in the cultural context of Latin America. Premission planning decisions that included time in each port and funding determined the services that were offered to host nations. Surgical, dental, immunizations, preventive medicine, and biomedical repair services had lasting impacts. COMFORT and similar hospital ships are a superior platform to combatant vessels in providing comprehensive surgical care. Medical planning is heavily dependent upon statistics. Collection of additional clinical data on subsequent HCA missions could aid future planning decisions regarding manning, equipment, supplies, and objectives.

    Following Typhoon Haiyan, the World Health Organization (WHO) has been supporting the Government of the Philippines in coordinating the incoming relief supplies from more than 30 international humanitarian health organizations. During the 10 days in Abuyong, Philippines, the Chinese medical rescue team consisting of 50 experts specialized in clinical medicine and disease prevention and control action was taken including, medical treatment, environmental disinfection and health education. A total of 1,831 cases and 2,144 outpatients were treated, blood tests, B-ultrasound, electrocardiogram (ECG) and other laboratory examinations were carried out for more than 615 patients; a cumulative 90,000 square meters in external environment were disinfected, and more than 500 health education materials were handed out. Besides, measures of purifying drinking water, and rebuilding the local hospital have also been carried out. The international emergency response to the Haiyan typhoon in Philippines contributed to reconstruct the local disaster health system by the activities from international medical emergency rescue. To improve the capacity of international medical emergency rescue in disaster, the special project of foreign medical emergency rescue should be set in countries' medical emergency rescue, and disaster emergency medical rescue should be reserved as a conventional capacity.

    Background The United States Department of Defense participates in more than 500 missions every year, including humanitarian assistance and disaster relief, as part of medical stability operations. This study assessed perceptions of active-duty physicians regarding these activities and related these findings to the retention and overall satisfaction of healthcare professionals. Methods and Findings An Internet-based survey was developed and validated. Of the 667 physicians who responded to the survey, 47% had participated in at least one mission. On a 7-point, Likert-type response scale, physicians reported favorable overall satisfaction with their participation in these missions (mean  = 5.74). Perceived benefit was greatest for the United States (mean  = 5.56) and self (mean  = 5.39) compared to the target population (mean  = 4.82). These perceptions were related to participants' intentions to extend their military medical service (total model R2  = .37), with the strongest predictors being perceived benefit to self (β = .21, p<.01), the U.S. (β = .19, p<.01), and satisfaction (β = .18, p<.05). In addition, Air Force physicians reported higher levels of satisfaction (mean  = 6.10) than either Army (mean  = 5.27, Cohen's d = 0.75, p<.001) or Navy (mean  = 5.60, Cohen's d  = 0.46, p<.01) physicians. Conclusions Military physicians are largely satisfied with humanitarian missions, reporting the greatest benefit of such activities for themselves and the United States. Elucidation of factors that may increase the perceived benefit to the target populations is warranted. Satisfaction and perceived benefits of humanitarian missions were positively correlated with intentions to extend time in service. These findings could inform the larger humanitarian community as well as military medical practices for both recruiting and retaining medical professionals. PMID:23555564

    Objectives This systematic review aims to evaluate evidence on the effectiveness of sexual and reproductive health (SRH) interventions delivered in humanitarian crises. Setting Crisis affected low-income or middle-income countries. Participants Crisis-affected populations in low-income or middle-income countries. Method Peer-reviewed and grey literature sources were systematically searched for relevant papers detailing interventions from 1 January 1980 until the search date on 30 April 2013. Data from included studies were then extracted, and the papers’ quality evaluated using criteria based on modified STROBE and CONSORT checklists. Primary and secondary outcome measures Primary outcomes include, but are not limited to, changes in morbidity, mortality, sexually transmitted infection (STI) diagnosis or gender-based violence. Secondary outcomes include, but are not limited to, reported condom use or skilled attendance at birth. Primary outputs include, but are not limited to, condoms distributed or education courses taught. Results Of 7149 returned citations, 15 studies met the inclusion criteria. Only one randomised controlled trial was identified. The remaining observational studies were of moderate quality, demonstrating limited use of controls and inadequate attempts to address bias. Evidence of effectiveness was available for the following interventions: impregnated bed nets for pregnant women, subsidised refugee healthcare, female community health workers, and tiered community reproductive health services. Conclusions The limited evidence base for SRH interventions highlights the need for improved research on the effectiveness of public health interventions in humanitarian crises. While interventions proven efficacious in stable settings are being used in humanitarian efforts, more evidence is required to demonstrate the effectiveness of delivering and scaling-up such interventions in humanitarian crises.

    The current Ebola outbreak is the worst global public health emergency of our generation, and our global health care community must and will rise to serve those affected. Aid organizations participating in the Ebola response must carefully plan to carry out their responsibility to ensure the health, safety, and security of their responders. At the same time, individual health care workers and their employers must evaluate the ability of an aid organization to protect its workers in the complex environment of this unheralded Ebola outbreak. We present a minimum set of operational standards developed by a consortium of Boston-based hospitals that a professional organization should have in place to ensure the health, safety, and security of its staff in response to the Ebola virus disease outbreak.

  10. Camel milk, amoxicillin, and a prayer: medical pluralism and medical humanitarian aid in the Somali Region of Ethiopia.

    PubMed

    Carruth, Lauren

    2014-11-01

    This paper details how exposure to new clinics, diagnostic technologies, and pharmaceuticals during humanitarian relief operations in the Somali Region of Ethiopia shaped local pluralistic health systems and altered the ways in which residents subsequently conceived of and treated illness and disease. Despite rising demand for pharmaceuticals and diagnostic technologies among Somalis in Ethiopia, local ethnophysiologies continued to draw upon popular ideas about humoral flows, divine action, and spirit possession. Demands for therapeutic camel milk, Qur'anic spiritual healing, herbal remedies, and other historically popular therapies persisted, but were shaped by concurrent demands for and understandings of diagnostic biotechnologies and pharmaceutical medications. The reverse was also true: contemporary understandings and uses of non-biomedical healing modalities among Somalis shaped evaluations of clinical care, including healthcare during humanitarian responses. To illustrate these phenomena, based on ethnographic research in eastern Ethiopia between 2007 and 2009, this paper explores three topics vital to Somalis' pluralistic healthcare systems: camel milk and the management of digestive bile; women's experiences and clinical presentations with pain and disorder in their reproductive systems; and the rising popularity of high-tech diagnostic tests. I conclude that medical humanitarian aid never happens in a vacuum or among truly treatment-naïve populations. Instead, aid unfolds within ever-changing and pluralistic health cultures, and it permanently alters and is altered by the frames within which people evaluate and make future decisions about healthcare.

  11. The International Space Station: New Capabilities for Disaster Response and Humanitarian Aid

    The International Space Station (ISS) has been acquiring Earth imagery since 2000, primarily in the form of astronaut photography using hand-held film and digital cameras. Recent additions of more sophisticated multispectral and hyperspectral sensor systems have expanded both the capabilities and relevance of the ISS to basic research, applied Earth science, and development of new sensor technologies. Funding opportunities established within NASA, the US National Laboratories and the international partner organizations have generated instrument proposals that will further enhance these capabilities. With both internal and external sensor location options, and the availability of both automated and human-tended operational environments, the ISS is a unique platform within the constellation of Earth-observing satellites currently in orbit. Current progress and challenges associated with development of ISS terrestrial remote sensing capabilities in the area of disaster response and support of relief efforts will be presented. The ISS orbit allows for imaging of the Earth's surface at varying times of day and night, providing opportunities for data collection over approximately 95% of the populated regions. These opportunities are distinct from--yet augment--the data collection windows for the majority of sensors on polar-orbiting satellites. In addition to this potential for "being in the right place at the right time" to collect critical information on an evolving disaster, the presence of a human crew also allows for immediate recognition of an event from orbit, notification of relevant organizations on the ground, and re-tasking of available remote sensing resources to support humanitarian response and relief efforts. Challenges to establishing an integrated response capability are both technical (coordination of sensor targeting and data collection, rapid downlink and posting of data to a central accessible hub, timely generation and distribution of relevant data

    Exclusionary practices in dominant market-based systems are recognized as contributing to global health inequities. Undocumented immigrants are particularly vulnerable to unequal access to healthcare. Humanitarian NGOs strive to respond meaningfully to these health inequities among migrants and undocumented immigrants. Few studies describe the work of humanitarian NGOs that advocate for the right to health of undocumented immigrants in high-income countries. This paper discusses immigration, health, and human rights while examining solidarity, spirituality, and advocacy using a U.S.-based example of medical humanitarianism: the 'Our Lady of Guadalupe Free Clinic.' In 2011, the Free Clinic began in the basement of a Catholic parish in Minnesota in response to the lack of access to medical services for undocumented immigrants. Run by a local grassroots organization, it is held every six weeks and offers free primary healthcare to Latino immigrants and the uninsured. In this article, we examine the tricky relationship between humanitarianism and human rights in the U.S. Using ethnography, we draw on participant observation and interviews with 30 clinic volunteers, including health professionals, administrators, language interpreters, and spiritual leaders. The study was conducted September 2012-December 2013 in southern Minnesota. We examine how notions of solidarity, spirituality, and advocacy structure faith-based medical humanitarianism in the U.S. and explore the underlying tensions between the humanitarian mandate, spiritual teachings (social justice, solidarity), and political advocacy. Examining a moment of "crisis" in the Clinic, our study shows that volunteers experience the alliance between spirituality and advocacy with uneasiness. While a spiritual calling may initially motivate volunteers to serve, an embrace of human rights advocacy is important in a sustained effort to provide humanitarian medical care to individuals who fall outside of the political

    A Social-Learning Approach to Hazard-Related Knowledge Exchange: Boundary Workers at the Geoscience-Humanitarian Interface Keira Quinn (1), Dr Max Hope (1), Professor John McCloskey (1). (1)University of Ulster Peer-reviewed science has the potential to guide policy-makers and practitioners in developing robust responses to social problems and issues. Despite advances in hazard-related science, it can often be a challenge to translate findings into useful social applications. With natural hazards affecting 2.9 billion people between 2000 and 2012 the need for hazard science to be effectively communicated is undeniable. This is particularly so in humanitarian contexts as non-governmental organisations (NGOs) play a key role in the poorer nations most affected by natural disasters. Past methods of 'knowledge transfer' have tended to lead to misinterpretations and misrepresentations of science to the extent that it is often used incorrectly or not at all. 'Knowledge exchange' is currently heralded as a more effective means of bringing about successful communication and understanding, and is characterised by the presence of shared learning. Central to a knowledge exchange approach is an understanding of the social and organisational contexts within which learning takes place. Here we use Etienne Wenger's social-learning approach to analyse selected aspects of the social context influencing knowledge exchange across the geoscience-humanitarian interface. For Wenger (2000) Communities of Practice (CoP) are bounded organisational and social groups united by their own distinct values, goals and ways of working. The boundaries surrounding CoPs can act as barriers to knowledge exchange but can also create opportunities for new shared learning by challenging existing perspectives and practice. Drawing on the findings of ongoing qualitative research into communication and learning between earthquake scientists and humanitarian NGOs in UK/Ireland, this paper outlines a number

    A large variety of interacting complex systems are characterized by interactions occurring between more than two nodes. These systems are described by simplicial complexes. Simplicial complexes are formed by simplices (nodes, links, triangles, tetrahedra etc.) that have a natural geometric interpretation. As such simplicial complexes are widely used in quantum gravity approaches that involve a discretization of spacetime. Here, by extending our knowledge of growing complex networks to growing simplicial complexes we investigate the nature of the emergent geometry of complex networks and explore whether this geometry is hyperbolic. Specifically we show that an hyperbolic network geometry emerges spontaneously from models of growing simplicial complexes that are purely combinatorial. The statistical and geometrical properties of the growing simplicial complexes strongly depend on their dimensionality and display the major universal properties of real complex networks (scale-free degree distribution, small-world and communities) at the same time. Interestingly, when the network dynamics includes an heterogeneous fitness of the faces, the growing simplicial complex can undergo phase transitions that are reflected by relevant changes in the network geometry.

    2012-03-01

    Telemedicine networks for humanitarian purposes have evolved over the last decade or so in a largely autonomous way. Communication between them has been informal and relatively limited in scope. This situation could be improved by developing a comprehensive approach to the collection and dissemination of information. We propose the formation of a central 'clearing house' which would allow networks to exchange information and cases where appropriate. In order for a network to belong to the clearing house, it would need to conform to certain guidelines, which would ensure that safe and satisfactory standards would be maintained. We propose that a coordinators' conference should be held to discuss who would operate the clearing house and how it would be resourced. The creation of a central clearing house would facilitate the operation of the networks, particularly during periods of heavy workload, and lead to improved sustainability, thereby benefiting individual patients. We believe that more can be achieved by the networks acting together than by them acting independently.

    Seven long-running telemedicine networks were surveyed. The networks provided humanitarian services (clinical and educational) in developing countries, and had been in operation for periods of 5-15 years. The number of experts serving each network ranged from 15 to 513. The smallest network had a total of 10 requesters and the largest one had more than 500 requesters. The networks operated in nearly 60 countries. The seven networks managed a total of 1857 cases in 2011, i.e. an average of 265 cases per year per network. There was a significant growth in total activity, amounting to 100.3 cases per year during the 15 year study period. In 2011, network activity was 50-700 teleconsultations per network. There were clear differences in the patterns of activity, with some networks managing an increasing caseload, and others managing a slowly reducing caseload. The seven networks had published a total of 44 papers listed in Medline which summarized the evidence resulting from the delivery of services by telemedicine. There was a dearth of information about clinical and cost-effectiveness. Nevertheless, the services were widely appreciated by referring doctors, considered to be clinically useful, and there were indications that clinical outcomes for telemedicine patients were often improved. Despite a lack of formal evidence, the present study suggests that telemedicine can provide clinically useful services in developing countries.

    Background The prevalence of cardiovascular disease and its associated mortality continue to increase in developing countries despite unparalleled improvements in cardiovascular medicine over the last century. Cardiovascular care in developing nations is often constrained by limited resources, poor access, lack of specialty training and inadequate financial support. Medical volunteerism by experienced health care teams can provide mentorship, medical expertise and health policy advice to local teams and improve cardiovascular patient outcomes. Methods We report our experience from annual successive humanitarian medical missions to Arequipa, Peru, and describe the challenges faced when performing cardiovascular interventions with limited resources. Results Over a 2-year period, we performed a total of 15 cardiac repairs in patients with rheumatic, congenital and ischemic heart disease. We assessed and managed 150 patients in an outpatient clinic, including 7 patients at 1-year postoperative follow-up. Conclusion Despite multiple challenges, we were able to help the local team deliver advanced cardiovascular care to many patients with few alternatives and achieve good early and 1-year outcomes. Interdisciplinary education at all levels of cardiac care, including preoperative assessment, intraoperative surgical and anesthetic details, and postoperative critical care management, were major goals for our medical missions.

    Traditional smoky cooking fires are one of today's greatest environmental threats to human life. These fires, used by 40% of the global population, cause 3.9 million annual premature deaths. "Clean cookstoves" have potential to improve this situation; however, most cookstove programs do not employ objective measurement of adoption to inform design, marketing, subsidies, finance, or dissemination practices. Lack of data prevents insights and may contribute to consistently low adoption rates. In this study, we used sensors and surveys to measure objective versus self-reported adoption of freely-distributed cookstoves in an internally displaced persons camp in Darfur, Sudan. Our data insights demonstrate how to effectively measure and promote adoption, especially in a humanitarian crisis. With sensors, we measured that 71% of participants were cookstove "users" compared to 95% of respondents reporting the improved cookstove was their "primary cookstove." No line of survey questioning, whether direct or indirect, predicted sensor-measured usage. For participants who rarely or never used their cookstoves after initial dissemination ("non-users"), we found significant increases in adoption after a simple followup survey (p = 0.001). The followup converted 83% of prior "non-users" to "users" with average daily adoption of 1.7 cooking hours over 2.2 meals. This increased adoption, which we posit resulted from cookstove familiarization and social conformity, was sustained for a 2-week observation period post intervention.

    2017-02-04

    Ongoing failure by the international community to resolve the Syrian conflict has led to destruction of critical infrastructure. This includes the collapse of the Syrian health system, leaving millions of internally displaced persons (IDPs) in urgent need of healthcare services. As the conflict intensifies, IDP populations are suffering from infectious and non-communicable disease risks, poor maternal and child health outcomes, trauma, and mental health issues, while healthcare workers continually exit the country. Healthcare workers who remain face significant challenges, including systematic attacks on healthcare facilities and conditions that severely inhibit healthcare delivery and assistance. Within this conflict-driven public health crisis, the most susceptible population is arguably the IDP. Though the fundamental 'right to health' is a recognised international legal principle, its application is inadequate due to limited recognition by the UN Security Council and stymied global governance by the broader international community. These factors have also negatively impacted other vulnerable groups other than IDPs, such as refugees and ethnic minorities, who may or may not be displaced. Hence, this article reviews the current Syrian conflict, assesses challenges with local and global governance for IDPs, and explores potential governance solutions needed to address this health and humanitarian crisis.

    Humanitarian cleft surgery has long been provided by teams from resource-rich countries traveling for short-term missions to resource-poor countries. After identifying an area of durable unmet need through surgical missions, Operation Smile constructed a permanent center for cleft care in Northeast India. The Operation Smile Guwahati Comprehensive Cleft Care Center (GCCCC) uses a high-volume subspecialized institution to provide safe, quality, comprehensive, and cost-effective cleft care to a highly vulnerable patient population in Assam, India. The purpose of this study was to profile the expenses of several cleft missions carried out in Assam and to compare these to the expenditures of the permanent comprehensive cleft care center. We reviewed financial data from 4 Operation Smile missions in Assam between December 2009 and February 2011 and from the GCCCC for the 2012-2013 fiscal year. Expenses from the 2 models were categorized and compared. In the studied period, 33% of the mission expenses were spent locally compared to 94% of those of the center. The largest expenses in the mission model were air travel (48.8%) and hotel expenses (21.6%) for the team, whereas salaries (46.3%) and infrastructure costs (19.8%) made up the largest fractions of expenses in the center model. The evolution from mission-based care to a specialty hospital model in Guwahati incorporated a transition from vertical inputs to investments in infrastructure and human capital to create a sustainable local care delivery system.

    The vesico-vaginal fistula from prolonged obstructed labor has become a rarity in the industrialized West but still continues to afflict millions of women in impoverished Third World countries. As awareness of this problem has grown more widespread, increasing numbers of American and European surgeons are volunteering to go on short-term medical mission trips to perform fistula repair operations in African and Asian countries. Although motivated by genuine humanitarian concerns, such projects may serve to promote 'fistula tourism' rather than significant improvements in the medical infrastructure of the countries where these problems exist. This article raises practical and ethical questions that ought to be asked about 'fistula trips' of this kind, and suggests strategies to help insure that unintended harm does not result from such projects. The importance of accurate data collection, thoughtful study design, critical ethical oversight, logistical and financial support systems, and the importance of nurturing local capacity are stressed. The most critical elements in the development of successful programs for treating obstetric vesico-vaginal fistulas are a commitment to developing holistic approaches that meet the multifaceted needs of the fistula victim and identifying and supporting a 'fistula champion' who can provide passionate advocacy for these women at the local level to sustain the momentum necessary to make long-term success a reality for such programs.

    Sato, Motoyuki

    Ground Penetrating Radar (GPR) has been widely used applications which include detection of subsurface facilities, concrete inspection and archaeology. Among these applications, humanitarian demining is still difficult task. Since 2002, we have developed a new hand-held land mine detection dual-sensor ALIS. ALIS is equipped with a metal detector and a GPR, and it has a sensor tracking system, which can record the GPR and Metal detector signal with its location. ALIS can process the data and is used for image re-construction by migration processing. ALIS is the only one mine detection system in the world which can visualize the GPR image by hand scanning. We found that the migration processing can reduce the clutter and gives us clear images of buried mines. After several tests of ALIS in mine affected courtiers, operation of ALIS in mine fields in Cambodia started in summer 2009. Two sets of ALIS have been operated in Cambodia and more than 77 antipersonnel mines have been detected and 137,000m2 farmland was cleaned.

    Much debate exists regarding the need, acceptability, and value of humanitarian medical assistance. We conducted a cross-sectional study on 457 children under 5 years from four remote riverine communities in the Peruvian Amazon and collected anthropometric measures, blood samples (1–4 years), and stool samples. Focus groups and key informant interviews assessed perspectives regarding medical aid delivered by foreigners. The prevalence of stunting, anemia, and intestinal parasites was 20%, 37%, and 62%, respectively. Infection with multiple parasites, usually geohelminths, was detected in 41% of children. The prevalence of intestinal parasites both individual and polyparasitism increased with age. Participants from smaller communities less exposed to foreigners expressed lack of trust and fear of them. However, participants from all communities were positive about foreigners visiting to provide health support. Prevalent health needs such as parasitic infections and anemia may be addressed by short-term medical interventions. There is a perceived openness to and acceptability of medical assistance delivered by foreign personnel. PMID:25846293

    2008-05-01

    Reproductive health care for internally displaced persons (IDPs) is recognised by the Inter-Agency Working Group on Reproductive Health in Refugee Situations and the Reproductive Health Response in Conflict Consortium as a neglected area in humanitarian relief operations. To identify barriers to agencies providing reproductive health care to IDPs, and their strategies for overcoming these barriers, we interviewed representatives of 12 relief and development agencies providing health care to conflict-affected populations. Although material and human resources are significant constraints on agencies, the main challenge is to tackle ideological, managerial and policy barriers, and those related to donor influence. The absence of a legal instrument that recognises IDPs internationally has contributed to the difficulties agencies face in systematically reaching IDPs. Our findings suggest that considerable efforts are needed to close the gap between international commitments and the provision of services at field level. We recommend that agencies carry out awareness-raising activities internally and among partner organisations and donors, strengthen internal organisation and inter-agency collaboration and share expertise in order to maximise benefits and save resources at the local level. We also recommend exploring the possibility of an international convention to protect the rights of internally displaced persons.

    Military dietitians have long been valued members of the health care team, called on for their expertise as early as World War I. However, in the more recent conflicts over the past two decades, their role in health care delivery as a component of medical stability operations has been largely undefined. The purpose of this study was to explore the types of missions supported by U.S. military dietitians and characterize any unique competencies critical to their success during these missions using an online questionnaire. Sixty-five military dietitians responded to an online questionnaire and 49 (75%) shared their deployment experiences, lessons learned, and recommendations for future training based on 57 deployments from 1975 to 2014. Results indicated that during these deployments nutrition- and dietetics-related competencies were capitalized along with staff positions in support of combat and humanitarian operations. The majority (n = 24; 51%) valued mentorship as a useful resource before deployments followed by field experience (45%) and Web-based training (43%). The authors propose standardized formal training for military dietitians aimed at increasing strategic level awareness of partnerships and collaborations between U.S. Government and interagency organizations; these associations are vital for sustained synchronization of global health efforts.

    The U.S. military provides humanitarian assistance in many areas around the globe. With recent changes in the force structure of the U.S. Army, internal medicine physicians are now at the forefront of providing this care, but the extent of their involvement is not known. This study measured the frequency with which recently trained Army internists provided humanitarian assistance, and it assessed their perceived preparedness for such missions. All graduates from Army internal medicine programs for 4 consecutive years were invited by e-mail to participate in an Internet-based survey. Eighty-nine personnel (49% of those contacted) completed the survey. Of those in a deployable position for >6 months, 72% provided medical humanitarian assistance. Most thought that additional training was needed, especially in tropical disease management, sanitation, and the practices of civilian humanitarian workers. This study demonstrates that military-trained internists are frequently involved in humanitarian assistance medicine, and it suggests that they might benefit from additional training.

    Pakistan is highly disaster-prone, with three major flood disasters occurred in the past three years, yet major losses are not inevitable. Farming-based families still struggling to recover from 2010 and 2011 floods have again faced another bad monsoon season in 2012. Meanwhile, the likelihood of yet more natural disasters in the future is high as the phenomenon of climate change is increasing the prevalence of extreme weather conditions. Even with less rainfall, the risk of flooding this year remains high, while many villages have not fully recovered from the 2011-2012 floods. It is of utmost importance to support the most vulnerable rural communities to recover their flood-affected livelihoods. In the meantime, prioritizing disaster preparedness through flood hazard and population mapping is crucial to ensure that realistic contingency plans are in place to deliver an effective and timely response and reduce the impact of floods before they strike. To increase preparedness in future floods, an integrated approach that builds the resilience of flood affected community and enhances emergency preparedness based on reliable data is critical. We present here the innovative methodology developed for estimating population and livelihood that could potentially be affected by a future flood scenario, as well as a methodology for knowing where these people are located, along with an overview of their livelihood pattern. This project has used only freely available dataset, due to the urgency of providing a toolbox to the humanitarian community and the absence of readily available detailed information on natural hazards and exposure in Pakistan. The estimated figures resulting from this project, would provide the Food Security stakeholders with adequate information and data for programming a tailored response in case of floods during future monsoon season. For the purpose of preparedness, understanding the risks, and its potential magnitude, is crucial to provide decision

  15. Breastfeeding promotion: a vital emergency intervention disregarded?

    PubMed

    Patten, T

    1997-09-01

    This article explains the need for promotion of breast feeding among donors and humanitarian aid organizations in emergency situations. Breast feeding offers fewer health hazards than artificial feeding in war or emergency settings. Breast feeding normally also provides the advantage of immune protection for the infant, psychological well-being of the mother and child, fertility regulation, an hygienic food source, and an economic means of feeding infants. Many war casualties are women and children. War casualties are exposed to injury, the disruption of water and food supplies, epidemics, and other detrimental social and environmental conditions. Refugees tend to have a poorer psychological state of health than control populations. This is attributed to displacement, sexual violence, loss of emotion support, and loss of cultural traditions. Women lose traditional sources of independence and authority when their homes are destroyed. Prevailing conditions of conflict that contribute to a mother's anxiety and insecurity may interfere with a mother's "let down" reflex and lactation. Health professionals in emergency settings need to be aware of breast feeding difficulties. Mothers with the proper encouragement and support can overcome their breast feeding difficulties. The promotion of breast feeding is a practical means of helping women gain control over their lives. Breast feeding allows women to feed their infants safely and effectively, to feed their infants by a cheap and sustainable means, to contribute to the well-being of another, to rebuild feelings of confidence, and to reduce intervention costs. Promotion of breast feeding can be started without delay.

    By 2000, an estimated 80% of South America’s population lived in urban areas (Veblen et al., The Physical Geography of South America, Oxford University Press, 2007). A significant fraction of those urban dwellers resides in the capital cities which are major economic centers and act as magnets for rural poor and refugees. This population concentration includes many residents living in extreme poverty in substandard and informal housing, often on the margins of these capital cities and sometimes on steep slopes, greatly compounding the vulnerability to natural hazards. We are analyzing the humanitarian and economic risk for six of the seismically most-at-risk South American capitals along the northern and western plate boundaries of South America: Caracas, Venezuela; Bogotá, Colombia; Quito, Ecuador; Lima, Perú; La Paz, Bolivia; and Santiago, Chile. Impacts are provided in the form of expected losses for a specific “likely” scenario earthquake and in a probabilistic format using exceedance probability curves (probability of exceeding a given loss in different return periods). Impacts to be quantified include: total economic losses, potential fatalities, potential serious injuries, and the number of displaced households. Probabilistic seismic hazard was developed in collaboration with numerous South American experts and includes subduction interface, intraslab, background crustal and, where available, active fault sources. A significant challenge for this study is to accurately account for the exposure and vulnerability of populations living in the informal, shanty areas. Combining analysis of aerial imagery and on-the-ground reconnaissance, we define between 20-30 “inventory districts” of relatively uniform construction styles within each capital. Statistical distributions of the different construction types and their characteristics (height, occupancy, year built, average value) are estimated for each district. In addition, working with local graduate

    This review links practice, funding, and evidence for interventions for mental health and psychosocial wellbeing in humanitarian settings. We studied practice by reviewing reports of mental health and psychosocial support activities (2007-10); funding by analysis of the financial tracking service and the creditor reporting system (2007-09); and interventions by systematic review and meta-analysis. In 160 reports, the five most commonly reported activities were basic counselling for individuals (39%); facilitation of community support of vulnerable individuals (23%); provision of child-friendly spaces (21%); support of community-initiated social support (21%); and basic counselling for groups and families (20%). Most interventions took place and were funded outside national mental health and protection systems. 32 controlled studies of interventions were identified, 13 of which were randomised controlled trials (RCTs) that met the criteria for meta-analysis. Two studies showed promising effects for strengthening community and family supports. Psychosocial wellbeing was not included as an outcome in the meta-analysis, because its definition varied across studies. In adults with symptoms of post-traumatic stress disorder (PTSD), meta-analysis of seven RCTs showed beneficial effects for several interventions (psychotherapy and psychosocial supports) compared with usual care or waiting list (standardised mean difference [SMD] -0·38, 95% CI -0·55 to -0·20). In children, meta-analysis of four RCTs failed to show an effect for symptoms of PTSD (-0·36, -0·83 to 0·10), but showed a beneficial effect of interventions (group psychotherapy, school-based support, and other psychosocial support) for internalising symptoms (six RCTs; SMD -0·24, -0·40 to -0·09). Overall, research and evidence focuses on interventions that are infrequently implemented, whereas the most commonly used interventions have had little rigorous scrutiny.

    Background Although nurses play an important role in humanitarian aid and disaster relief (HA/DR), little is known about the nursing activities that are performed in HA/DR. We aimed to clarify the nursing activities performed by Japanese nurses in HA/DR and to examine the factors associated with the frequency of nursing activities. Methods A self-administered questionnaire survey was completed by 147 nurses with HA/DR experience. The survey extracted information on demographic characteristics, past experience (e.g., disaster medical training experience, HA/DR experience), circumstances surrounding their dispatched to HA/DR (e.g., team size, disaster type, post-disaster phase, mission term), and the frequency of nursing activities performed under HA/DR. The frequency of nursing activities was rated on a 5-point Likert scale. Evaluation of nursing activities was conducted based on the “nursing activity score”, which represents the frequency of each nursing activity. Factors related to the nursing activity score were evaluated by multiple logistic regression analysis. Results Nurses were involved in 27 nursing activities in HA/DR, 10 of which were performed frequently. On analysis, factors significantly associated with nursing activity score were nursing license as a registered nurse (OR 7.79, 95% CI 2.95–20.57), two or more experiences with disaster medical training (OR 2.90 95%, CI 1.12–7.49) and a post-disaster phase of three weeks or longer (OR 8.77, 95% CI 2.59–29.67). Conclusions These results will contribute to the design of evidence-based disaster medical training that improves the quality of nursing activities. PMID:26959351

    Dr. Bayrakal believes that the time has come for the family physician to deal with minor psychiatric disturbances in his office as well as psychiatric emergencies in the emergency department. The newly emerging medico-social philosophy of both the federal and provincial governments, he says, is giving greater responsibility and authority to the family physician in every area of medicine, including psychiatry. The author discusses major psychiatric emergencies (suicide, suicidal attempt, homicide, social scandal, as well as other psychiatric emergencies) on the ward including adolescent psychiatry. (The descriptions and treatment procedures are given on a concrete clinical level without theoretical overload.) In the family physician's work, psychological understanding is of profound importance. Giving him the added scope of psychiatric consideration to see the patient in bio-psycho-social totality will enable him to practice a more humanized form of medicine. PMID:20468779

    The term 'emergency contraception', as employed in this paper, refers to methods that are used as emergency procedures to prevent pregnancy following unprotected intercourse. Alternative, less appropriate, terms are postcoital and 'morning-after' contraception. References to postcoital preparations can be found as far back as 1500 BC in Egyptian papyri, but it was not until fairly recently that contraceptive research has been able to at least partially fulfill that need. The development of hormonal methods of emergency contraception goes back to the 1960s when the first human trials of postcoitally administered high-dose oestrogens were undertaken. Combined oestrogen- progestogen combination therapy (the so-called Yuzpe regimen) was introduced in the early 1970s, while the postcoital insertion of an intrauterine contraceptive device (IUD) for emergency contraception was first reported in 1976. Other compounds that have been tested more recently include levonorgestrel, the antiprogestogen mifepristone, and danazol. Although there is some debate about the magnitude of the protective effect, few people question the important role that emergency contraception can play in preventing unwanted pregnancy and hence maternal mortality and morbidity resulting from unsafe abortion. Given that the most often used methods of emergency contraception, namely the Yuzpe regimen and postcoital insertion of an IUD, rely on technology that has been available for some 30 years, family planning programmes that claim to be concerned with improving women's reproductive health, cannot really be excused if they do not provide emergency contraception as part of their routine services.

    Human exposure to high-linear energy transfer α-particles includes environmental (e.g. radon gas and its decay progeny), medical (e.g. radiopharmaceuticals) and occupational (nuclear industry) sources. The associated health risks of α-particle exposure for lung cancer are well documented however the risk estimates for leukaemia remain uncertain. To further our understanding of α-particle effects in target cells for leukaemogenesis and also to seek general markers of individual exposure to α-particles, this study assessed the transmission of chromosomal damage initially-induced in human haemopoietic stem and progenitor cells after exposure to high-LET α-particles. Cells surviving exposure were differentiated into mature T-cells by extra-thymic T-cell differentiation in vitro. Multiplex fluorescence in situ hybridisation (M-FISH) analysis of naïve T-cell populations showed the occurrence of stable (clonal) complex chromosome aberrations consistent with those that are characteristically induced in spherical cells by the traversal of a single α-particle track. Additionally, complex chromosome exchanges were observed in the progeny of irradiated mature T-cell populations. In addition to this, newly arising de novo chromosome aberrations were detected in cells which possessed clonal markers of α-particle exposure and also in cells which did not show any evidence of previous exposure, suggesting ongoing genomic instability in these populations. Our findings support the usefulness and reliability of employing complex chromosome exchanges as indicators of past or ongoing exposure to high-LET radiation and demonstrate the potential applicability to evaluate health risks associated with α-particle exposure.

    Spain was officially represented at the preliminary international conference the "International Committee for the Assistance to Sick and Wounded Soldiers" (better known as the "Geneva Committee") organised at Geneva in October 1863; and joined the Red Cross one year later on the occasion of the first Geneva Convention in August 1864. This article explores the ambivalence between the humanitarian ethos and the military efficiency in the early Spanish Red Cross through the works of Nicasio Landa (1830-1891). A medical major of the Spanish Military Health Service, the co-founder of the Spanish section of the Red Cross in 1864, and its general inspector in 1867, Landa was its most active promoter, and responsible for its connections with the Geneva Committee and other national sections of this international association during its early times. He was not only an active correspondent, but also a prolific author of monographs, leaflets and articles in specialized and daily newspapers on humanitarianism and war medicine, in addition to being the founder of the Spanish Red Cross journal La Caridad en la Guerra in 1870.

    Implementation of the Cluster Approach has been a major recent development in the humanitarian system. The aim of this study was to explore the strengths and weaknesses of the humanitarian Cluster Approach in relation to services for sexual and reproductive health (SRH) [including gender-based violence (GBV)] in northern Uganda, which is recovering from over 20 years of armed conflict. Face-to-face and telephone, semistructured, qualitative interviews were conducted in 2009 with purposively selected key informants from governmental, non-governmental, United Nations and donor agencies working in northern Uganda. Respondents noted a number of contributions of the Cluster Approach, including improved co-ordination of SRH services and stronger advocacy. However, concerns were raised about the low prioritisation, limited leadership and capacity, and standard setting for SRH services. Concerns were also raised about limited planning and capacity for dissolution of the Clusters in the transition to recovery and development in northern Uganda. Despite a number of contributions made by the Cluster Approach, particularly for responding to GBV, there were many concerns about its limited influence on SRH services. There were also concerns that the transition to recovery and development in northern Uganda may not result in reproductive health services being sufficiently strengthened.

    Currently there is no consensus on how to identify pregnant women as acutely malnourished and when to enroll them in nutritional programmes. Médecins Sans Frontières Switzerland undertook a literature review with the purpose of determining values of anthropometric indicators for acute malnutrition that are associated with adverse birth outcomes (such as low birth weight (LBW)), pre-term birth and intra-uterine growth retardation (IUGR). A literature search in PUBMED was done covering 1 January 1995 to 12 September 2012 with the key terms maternal anthropometry and pregnancy. The review focused on the humanitarian context. Mid-upper-arm circumference (MUAC) was identified as the preferential indicator of choice because of its relatively strong association with LBW, narrow range of cut-off values, simplicity of measurement (important in humanitarian settings) and it does not require prior knowledge of gestational age. The MUAC values below which most adverse effects were identified were <22 and <23 cm. A conservative cut-off of <23 cm is recommended to include most pregnant women at risk of LBW for their infants in the African and Asian contexts. PMID:23787989

    The primary mission of the US Navy (USN) is to maintain superior naval forces capable of winning wars, deterring aggression, and maintaining freedom of the seas. However, a major core capability of the present-day USN includes the ability to effectively and rapidly provide humanitarian assistance and disaster response whenever the need arises. Occurring annually since 2006, Pacific Partnership is an ongoing USN operation that aims to strengthen regional alliances and improve delivery of humanitarian assistance and disaster relief. A major focus of Pacific Partnership 2010 was the delivery of medical care to underserved communities in the region. A significant portion of the medical mission was specifically directed toward the treatment of patients with cleft lip and palate. As the main operational platform, the USN Ship Mercy provided an unparalleled environment in which to provide state-of-the-art multidisciplinary treatment to patients with cleft lip and palate. With the cooperation of host nations and locally active nongovernmental organizations, a sustainable model for providing treatment for cleft lip and palate can be developed.

    Mitochondrial malfunction appears to be intimately associated with age and age-related complex disorders but the precise pathological relevance of such malfunction remains unclear. Mitochondrial, and more specifically bioenergetic, malfunction is commonly encountered in cancer, degenerative disorders and aging. The identification of a mitochondrial-nuclear retrograde signaling pathway in yeast has facilitated the study of the corresponding retrograde signaling mechanisms induced in response to mitochondrial malfunction in mammals including human. Mitochondrial-nuclear crosstalk is critical for the maintenance of cellular homeostasis, and some mitochondrial DNA mutations may perturb crosstalk signaling. However, ascertaining whether mitochondrial malfunction is a cause or a consequence of disease development will be key to determining whether or not impaired crosstalk signaling is of direct pathological and hence therapeutic relevance. Here, we review what is known about the nuclear adaptive compensatory mechanisms induced in response to mitochondrial malfunction. We discuss the role of mitochondrial DNA variants in modulating the penetrance of human inherited disease caused by mutations in the nuclear genome and explore the underlying mechanisms by which they influence the retrograde response. We conclude that mitochondrial DNA variants have the potential to induce molecular signals through the mitochondrial-nuclear crosstalk mechanism, thereby promoting nuclear compensation in response to mitochondrial malfunction. The implications for the development of genetic or pharmaceutical interventions for the treatment of mitochondrial malfunction in complex disease are also explored.

    Emergency contraception is used to prevent pregnancy after a coital act not adequately protected by a regular method of contraception. In contrast to early medical abortion, emergency contraception prevents a pregnancy from starting and does not disrupt an established pregnancy. The most commonly used approaches consist of two oral doses of contraceptive steroids. The levonorgestrel-only regimen (levonorgestrel, 0.75 mg, repeated in 12 hours) appears to be more effective and better tolerated than the Yuzpe regimen (ethinyl estradiol, 100 microg, and levonorgestrel, 0.5 mg, repeated in 12 hours). In the largest randomized, controlled trial to date, levonorgestrel prevented about 85% of pregnancies that would have occurred without its use. Hormonal emergency contraception has no known medical contraindications, although it is not indicated for suspected or confirmed pregnancy. However, if hormonal emergency contraception is inadvertently taken in early pregnancy, neither the woman nor the fetus will be harmed. Nausea and vomiting associated with the Yuzpe regimen can be reduced by prophylactic use of meclizine. A strong medical and legal case exists for making hormonal emergency contraception available over the counter, as has happened in countries other than the United States. Easier access to and wider use of emergency contraception could dramatically lower the high rates of unintended pregnancy and induced abortion in the United States.

    Anorectal emergencies refer to anorectal disorders presenting with some alarming symptoms such as acute anal pain and bleeding which might require an immediate management. This article deals with the diagnosis and management of common anorectal emergencies such as acutely thrombosed external hemorrhoid, thrombosed or strangulated internal hemorrhoid, bleeding hemorrhoid, bleeding anorectal varices, anal fissure, irreducible or strangulated rectal prolapse, anorectal abscess, perineal necrotizing fasciitis (Fournier gangrene), retained anorectal foreign bodies and obstructing rectal cancer. Sexually transmitted diseases as anorectal non-surgical emergencies and some anorectal emergencies in neonates are also discussed. The last part of this review dedicates to the management of early complications following common anorectal procedures that may present as an emergency including acute urinary retention, bleeding, fecal impaction and anorectal sepsis. Although many of anorectal disorders presenting in an emergency setting are not life-threatening and may be successfully treated in an outpatient clinic, an accurate diagnosis and proper management remains a challenging problem for clinicians. A detailed history taking and a careful physical examination, including digital rectal examination and anoscopy, is essential for correct diagnosis and plan of treatment. In some cases, some imaging examinations, such as endoanal ultrasonography and computerized tomography scan of whole abdomen, are required. If in doubt, the attending physicians should not hesitate to consult an expert e.g., colorectal surgeon about the diagnosis, proper management and appropriate follow-up. PMID:27468181

    Two oral postcoital contraceptive agents are currently available. The first is a 2 x 2 pill; the second is a 5 x 5. Both release a higher dose of hormones than conventional contraceptive pills. Success rates range between 96% and 99%. They must be taken within 72 hours of intercourse. Side effects include nausea and vomiting. Contraindications are the same as for the common oral contraceptives. The contraceptive mode of action can be any of the following: 1) by making the lining of the uterus unreceptive; 2) by slowing the movement of the egg in the fallopian tube; or 3) by affecting the release of the egg. Emergency contraceptive pills have no effect once implantation takes place. The IUD can be used as an emergency postcoital contraceptive method if placed within 10 days of coitus. They are usually placed within 5-7 days because of laws regarding when birth control becomes abortion. One failure has been reported in Great Britain (December, 1993). Side effects are the same as with regular use. RU486/PG may be used in the future as an emergency contraceptive agent. Research is in progress on success rates and side effects. This agent could potentially be used at any time. Currently, emergency contraception can only be obtained by prescription. Limited hours and interrogating staff are obstacles in such emergencies. British women's groups are asking that emergency oral contraceptive pills be made available over the counter with advice from the pharmacist.

    Four truck drivers involved in a humanitarian mission across the Sahara towards Mali fell ill 15 days after their return. Plasmodium falciparum malaria (thankfully, non pernicious) was diagnosed with 3 to 4 days delay. The four drivers had been treated with chloroquine and proguanil but the dosage may have been insufficient with regard to their body weight (average weight = 110 kg). These 4 travelers had all slept outside (in Tintane, near Kiffa in Mauritania), without any anti-vectorial protection, whereas their other 8 companions (none of whom caught malaria) had slept in their vehicles. The evolution of the 4 cases was favourable despite the difficulties involved in urgently obtaining sufficient amounts of quinine for treatment. How can these cases be explained in relation to prophylactic treatment of associated chloroquine and proguanil? One explanation might be resistance of the P. falciparum strain. We were unable to study this possibility. The high incidence and similitude of cases points towards a hypothesis of resistance both to proguanil and chloroquine. Resistance to chloroquine, as has been formally ascertained in Mauritania, reinforces such a conviction. And yet prophylaxis does not prevent pernicious malaria. This clinical form of the disease, with P. falciparum primo-invasion occurring under rigorous chemoprophylaxis is characteristic of a partially resistant strain. The most reasonable explanation besides "chance" is that we are dealing here with a partially resistant strain of Plasmodium falciparum which is thus also partially sensitive to--in this case highly effective--therapeutic treatment. Indeed, chloroquino-resistant strains are more sensitive to mefloquine and halofantrine. Another explanation might be under-dosage of Savarine with relation to the body weight of these 4 patients. We should be aware of adapting more rigorously the posology of prescribed prophylaxis. But above all, this outbreak should remind us that we should recommend to
