Wicke, Daniel
The DØ experiment faces many challenges in terms of enabling access to large datasets for physicists on four continents. The strategy for solving these problems on worldwide distributed computing clusters is presented. Since the beginning of Run II of the Tevatron (March 2001) all Monte-Carlo simulations for the experiment have been produced at remote systems. For data analysis, a system of regional analysis centers (RACs) was established which supply the associated institutes with the data. This structure, which is similar to the tiered structure foreseen for the LHC was used in Fall 2003 to reprocess all DØ data with a much improved version of the reconstruction software. This makes DØ the first running experiment that has implemented and operated all important computing tasks of a high energy physics experiment on systems distributed worldwide.

The current environmental pollution and destruction have developed into a world-wide major social problem that threatens human survival and development. Environmental monitoring is the prerequisite and basis of environmental governance, but overall, the current environmental monitoring system is facing a series of problems. Based on the electrochemical sensor, this paper designs a small, low-cost, easy to layout urban environmental quality monitoring terminal, and multi-terminal constitutes a distributed network. The system has been small-scale demonstration applications and has confirmed that the system is suitable for large-scale promotion

Hepatitis C virus (HCV) infection is a major health problem worldwide. Chronic HCV infection may in the long run cause cirrhosis, hepatic decompensation and hepatocellular carcinoma, with an ultimate disease burden of at least 350,000 deaths per year worldwide. The new generation of highly effective direct acting antivirals (DAA) to treat HCV infection brings major promises to infected patients in terms of exceedingly high rates of sustained virological response (SVR) but also of tolerability, allowing even the sickest patients to be treated. Even in the face of the excellent safety and efficacy and wide theoretical applicability of these regimens, their introduction is currently facing cost and access issues denying their use to many patients in need. Health systems in all countries are facing a huge problem of distributive justice, since while they should guarantee individual rights, among which the right to health in its broader sense, therefore not limited to healing, but extended to quality of life, they must also grant equal access to the healthcare resources and keep the distribution system sustainable. In the face of a disease with a relatively unpredictable course, where many but not of all chronically infected will eventually die of liver disease, selective allocation of this costly resource is debatable. In most countries the favorite solution has been a stratification of patients for prioritization of treatment, which means allowing Interferon-free DAA treatment only in patients with advanced fibrosis or cirrhosis, while keeping on hold persons with lesser stages of liver disease. In this report, we will perform an ethical assessment addressing the issues linked to access to new therapies, prioritization and eligibility criteria, analyzing the meaning of the term "distributive justice" and the different approaches that can guide us (individualistic libertarianism, social utilitarianism and egalitarianism) on this specific matter. Even if over time the price of new DAA will be reduced through competition and eventual patent expiration, the phenomenon of high drug costs will go on in the next decades and we need adequate tools to face the problems of distributive justice that come with it.

ESPA, the Secondary Payload Adapter for Evolved Expendable Launch Vehicles, addresses two of the major problems currently facing the launch industry: the vibration environment of launch vehicles, and the high cost of putting satellites into orbit. (1) During the 1990s, billions of dollars have been lost due to satellite malfunctions, resulting in total or partial mission failure, which can be directly attributed to vibration loads experienced by payloads during launch. Flight data from several recent launches have shown that whole- spacecraft launch isolation is an excellent solution to this problem. (2) Despite growing worldwide interest in small satellites, launch costs continue to hinder the full exploitation of small satellite technology. Many small satellite users are faced with shrinking budgets, limiting the scope of what can be considered an 'affordable' launch opportunity.

Wong, Gabriel H Z; Pang, Weng Sun; Yap, Philip
2014-06-01
Singapore faces a rapidly aging population. By 2030, 19% of her population will be aged 65 years and above. Other Asian countries face similar problems, with South Korea having the fastest aging population worldwide, followed by China and Thailand. With Singapore possessing an advanced aging population, its policy provides a useful case study of eldercare to cater to evolving population demographics. This article will focus specifically on nursing homes and analyze current policies toward them, synthesize recommendations to improve long-term care, and justify a paradigm shift toward more holistic, humanistic, and multidimensional care.

Clostridium difficile-associated disease (CDAD) is caused by a spore-forming bacterium and can result in highly variable disease, ranging from mild diarrhoea to severe clinical manifestations. Infections are most commonly seen in hospital settings and are often associated with on-going antibiotic therapy. Incidences of CDAD have shown a sustained increase worldwide over the last ten years and a hypervirulent C. difficile strain, PCR ribotype 027/REA type BI/North American pulsed-field (NAP) type 1 (027/BI/NAP-1), has caused outbreaks in North America and Europe. In contrast, only a few reports of cases in Latin America have been published and the hypervirulent strain 027/BI/NAP-1 has, so far, only been reported in Costa Rica. The potential worldwide spread of this infection calls for epidemiological studies to characterize currently circulating strains and also highlights the need for increased awareness and vigilance among healthcare professionals in currently unaffected areas, such as Latin America. This review attempts to summarize reports of C. difficile infection worldwide, especially in Latin America, and aims to provide an introduction to the problems associated with this pathogen for those countries that might face outbreaks of epidemic strains of C. difficile for the first time in the near future.

Cost overrun is an increase of cost of project from approved budget which was signed by parties at the time of tender. Cost overrun in construction of highway projects is a common problem worldwide and construction industry of Pakistan is also facing this crucial problem of cost overrun in highway projects of Pakistan. The main objective of this research is to identify the causative factors of cost overrun in highway projects of Sindh province of Pakistan. A well designed questionnaire was developed based on 64 common factors of cost overrun from literature review. Developed questionnaire was distributed among selected 30 experts from owner/client, designer/consultant and contractor who have experience more than 20 years’ experience in highway projects. The collected data was statistical analyzed. After analysis results showed that delay process in payment by client, inadequate planning, client interference, poor contract management, delay of decision making, change of scope of project and financial problems faced by client were most causative factors of cost overrun in highway projects. This research will provide alertness to stakeholders of highway projects of Sindh province to avoid cost overrun in projects.

Patient safety and the problem of many hands
Dixon-Woods, Mary; Pronovost, Peter
2016-01-01
Summary Healthcare worldwide is faced with a crisis of patient safety: every day, everywhere, patients are injured during the course of their care. Notwithstanding occasional successes in relation to specific harms, safety as a system characteristic has remained elusive. We propose that one neglected reason why the safety problem has proved so stubborn is that healthcare suffers from a pathology known in the public administration literature as the problem of many hands. It is a problem that arises in contexts where multiple actors – organizations, individuals, groups – each contribute to effects seen at system level, but it remains difficult to hold any single actor responsible for these effects. Efforts by individual actors, including local quality improvement projects, may have the paradoxical effect of undermining system safety. Many challenges cannot be resolved by individual organisations, since they require whole-sector coordination and action. We call for recognition of the problem of many hands and for attention to be given to how it might most optimally be addressed in a healthcare context. PMID:26912578

Early marriage is a worldwide problem associated with a range of health and social consequences for teenage girls. Designing effective health interventions for managing early marriage needs to apply the community-based approaches. However, it has received less attention from policymakers and health researchers in Iran. Therefore, the current study aimed to explore determinants of early marriage from married girls' perspectives. The study was conducted from May 2013 to January 2015 in Ahvaz, Iran. A purposeful sampling method was used to select fifteen eligible participants. Data were collected through face-to-face, semistructured interviews and were analyzed using the conventional content analysis approach. Three categories emerged from the qualitative data including “family structure,” “Low autonomy in decision-making,” and “response to needs.” According to the results, although the participants were not ready to get married and intended to postpone their marriage, multiple factors such as individual and contextual factors propelled them to early marriage. Given that early marriage is a multifactorial problem, health care providers should consider a multidimensional approach to support and empower these vulnerable girls. PMID:27123012

The drag and heat reduction problem of hypersonic vehicles has always attracted the attention worldwide, and the experimental test approach is the basis of theoretical analysis and numerical simulation. In the current study, research progress of experimental investigations on drag and heat reduction are summarized by several kinds of mechanism, namely the forward-facing cavity, the opposing jet, the aerospike, the energy deposition and their combinational configurations, and the combinational configurations include the combinational opposing jet and forward-facing cavity concept and the combinational opposing jet and aerospike concept. The geometric models and flow conditions are emphasized, especially for the basic principle for the drag and heat flux reduction of each device. The measurement results of aerodynamic and aerothermodynamic are compared and analyzed as well, which can be a reference for assessing the accuracy of numerical results.

Manila street children face many sexual risks.
Connolly, M; Franchet, C N
1993-10-01
Estimates of as many of 100 million 5-18 year old children have been generated on the number of street children in urban areas worldwide. About 70% are on the streets, during the day and return home at night and 20-25% know where their families are, but prefer to live on the streets. 5-10% are without family and live on the streets. About 25-33% are young girls. Poverty is one of the driving forces for street children from rural areas. These children face illnesses such as respiratory infections, skin diseases, gastrointestinal problems, trauma, sexual abuse, exploitation, unwanted pregnancy, and sexually transmitted diseases, such as syphilis and gonorrhea. In Kenya, 4 out of 5 street children know that AIDS, while in India few are aware, and those who are have a fatalist attitude, since violence and death are faced by many of these children daily. As the numbers of street children have grown, so have health services to meet their needs. In the Philippines, Metro Manila has established a model program in providing health, nutrition, counseling, referral.

2015-01-01
Esophageal squamous cell carcinoma continues to heavily burden clinicians worldwide. Researchers have discovered the genomic landscape of esophageal squamous cell carcinoma, which holds promise for an era of personalized oncology care. One of the most pressing problems facing this issue is to improve the understanding of the newly available genomic data, and identify the driver-gene mutations, pathways, and networks. The emergence of a legion of novel targeted agents has generated much hope and hype regarding more potent treatment regimens, but the accuracy of drug selection is still arguable. Other problems, such as cancer heterogeneity, drug resistance, exceptional responders, and side effects, have to be surmounted. Evolving topics in personalized oncology, such as interpretation of genomics data, issues in targeted therapy, research approaches for targeted therapy, and future perspectives, will be discussed in this editorial.

Formation of paraffin (wax) in cold deepwater flowlines is a major problem for offshore operators of such facilities. Petrobras faces this problem continuously in its deepwater operations in the Campos basin, offshore Brazil. Since 1990, through its Petrobras Research Center (CENPES), the company has developed, extensively field tested, and recently commercialized, a novel technique for chemically removing such wax depositions. The process involves mixing and introducing to the line, two inorganic salts and organic solvents. The ensuing chemical reaction--which both generates nitrogen and heats the inside of the blocked flowline--allows the solvent to dissolve and dislodge the buildup, which ismore » then flushed from the line. The process is called the Nitrogen Generation System (SGN). Petrobras/CENPES has recently formed a joint venture with the Brazilian service company Maritima Navegacao e Engenharia Ltda. to offer SGN services worldwide.« less
Surveillance systems for intermodal transportation

Intermodal container monitoring is considered a major security issue in many major logistic companies and countries worldwide. Current representation of the problem, we face today, originated in 2002, right after the 9/11 attacks. Then, a new worldwide Container Security Initiative (CSI, 2002) was considered that shaped the perception of the transportation operations. Now more than 80 larger ports all over the world contribute to its further development and integration into everyday transportation operations and improve the regulations for the developing regions. Although, these new improvements allow us to feel safer and secure, constant management of transportation operations has become a very difficult problem for conventional data analysis methods and information systems. The paper deals with a proposal of a whole new concept for the improvement of the Containers Security Initiative (CSI) by virtually connecting safety, security processes and systems. A conceptual middleware approach with deployable intelligent agent modules is proposed to be used with possible scenarios and a testbed is used to test the solution. Middleware examples are visually programmed using National Instruments LabView software packages and Wireless sensor network hardware modules. An experimental software is used to evaluate he solution. This research is a contribution to the intermodal transportation and is intended to be used as a means or the development of intelligent transport systems.

Early childbearing is increasing worldwide, in both the developed and the developing countries. In 1975, 13 million young women became mothers before their 18th birthday. Such early childbearing causes major health, economic, social, and demographic problems. The disadvantages are felt by the young women, their sexual partners, the babies born to these women, and society in general. Reasons why adolescents are engaging in earlier sexual activity and experiencing more early pregnancies are enumerated. The 1st Interhemispheric Conference on Adolescent Fertility, sponsored by the Agency for International Development and other involved organizations, was held in 1976. The Conference participants made recommendations concerned with the legal, educational, and social aspects of early childbearing. Many youth education programs have been established since the Conference. Research projects have been launched to study the social consequences of adolescent pregnancy. Many more family life education and family planning services must be offered. A significant hindrance to such developments is the reluctance of adults around the world to recognize and deal with the problem.
The contribution of a gender perspective to the understanding of migrants' health
Llácer, Alicia; Zunzunegui, María Victoria; del Amo, Julia; Mazarrasa, Lucía; Bolůmar, Francisco
2007-01-01
In 2005 women represented approximately half of all 190 million international migrants worldwide. This paper addresses the need to integrate a gender perspective into epidemiological studies on migration and health, outlines conceptual gaps and discusses some methodological problems. We mainly consider the international voluntary migrant. Women may emigrate as wives or as workers in a labour market in which they face double segregation, both as migrants and as women. We highlight migrant women's heightened vulnerability to situations of violence, as well as important gaps in our knowledge of the possible differential health effects of factors such as poverty, unemployment, social networks and support, discrimination, health behaviours and use of services. We provide an overview of the problems of characterising migrant populations in the health information systems, and of possible biases in the health effects caused by failure to take the triple dimension of gender, social class and ethnicity into account.

Winter research and monitoring of icebound rivers, lakes, and coastal seas to date has usually involved seagoing civilian scientists leading survey efforts. However, because of poor weather conditions and a lack of safe research platforms, scientists collecting data during winter face some difficult and often insurmountable problems. To solve these problems and to further research and environmental monitoring goals, new partnerships can be formed through integrating efforts of the U.S. Coast Guard (USCG) with citizen science initiatives. USCG and a research group at Ohio's Bowling Green State University are entering the third year of such a partnership, in which icebreaking operations in Lake Erie using USCG Cutter Neah Bay support volunteer data collection. With two additional USCG vessels joining the program this winter season, the partnership serves as a timely and useful model for worldwide environmental research and monitoring through citizen science and government collaboration.
Nanotechnology for treating osteoporotic vertebral fractures
Gao, Chunxia; Wei, Donglei; Yang, Huilin; Chen, Tao; Yang, Lei
2015-01-01
Osteoporosis is a serious public health problem affecting hundreds of millions of aged people worldwide, with severe consequences including vertebral fractures that are associated with significant morbidity and mortality. To augment or treat osteoporotic vertebral fractures, a number of surgical approaches including minimally invasive vertebroplasty and kyphoplasty have been developed. However, these approaches face problems and difficulties with efficacy and long-term stability. Recent advances and progress in nanotechnology are opening up new opportunities to improve the surgical procedures for treating osteoporotic vertebral fractures. This article reviews the improvements enabled by new nanomaterials and focuses on new injectable biomaterials like bone cements and surgical instruments for treating vertebral fractures. This article also provides an introduction to osteoporotic vertebral fractures and current clinical treatments, along with the rationale and efficacy of utilizing nanomaterials to modify and improve biomaterials or instruments. In addition, perspectives on future trends with injectable bone cements and surgical instruments enhanced by nanotechnology are provided. PMID:26316746
About ATMPs, SOPs and GMP: The Hurdles to Produce Novel Skin Grafts for Clinical Use

2016-01-01
Background The treatment of severe full-thickness skin defects represents a significant and common clinical problem worldwide. A bio-engineered autologous skin substitute would significantly reduce the problems observed with today's gold standard. Methods Within 15 years of research, the Tissue Biology Research Unit of the University Children's Hospital Zurich has developed autologous tissue-engineered skin grafts based on collagen type I hydrogels. Those products are considered as advanced therapy medicinal products (ATMPs) and are routinely produced for clinical trials in a clean room facility following the guidelines for good manufacturing practice (GMP). This article focuses on hurdles observed for the translation of ATMPs from research into the GMP environment and clinical application. Results and Conclusion Personalized medicine in the field of rare diseases has great potential. However, ATMPs are mainly developed and promoted by academia, hospitals, and small companies, which face many obstacles such as high financial burdens. PMID:27781022

Marine debris is one of the most significant issues facing oceans worldwide. The sources of this debris vary depending on proximity to urban centres and the nature of activities within an area. This paper examines the influence of tourism in the southern Great Barrier Reef (GBR), and its contribution to litter levels in the region. By conducting beach debris surveys on occupied and unoccupied islands, this study found that debris was prevalent throughout the region with significant differences in material types between locations. The greatest source of debris from publically accessible islands was tourist-related, with this source also influencing debris loads on nearby uninhabited islands. A focus on debris at Heron Island, showed that sites close to amenities had greater levels of tourist-sourced items like cigarette butts. These findings indicate the contribution of tourists to this problem and that working with operators and managers is needed to minimise visitor impacts. Copyright © 2017 Elsevier Ltd.

To examine barriers to initiation and continuation of mental health treatment among individuals with common mental disorders. Data were from the World Health Organization (WHO) World Mental Health (WMH) surveys. Representative household samples were interviewed face to face in 24 countries. Reasons to initiate and continue treatment were examined in a subsample (n = 63,678) and analyzed at different levels of clinical severity. Among those with a DSM-IV disorder in the past 12 months, low perceived need was the most common reason for not initiating treatment and more common among moderate and mild than severe cases. Women and younger people with disorders were more likely to recognize a need for treatment. A desire to handle the problem on one's own was the most common barrier among respondents with a disorder who perceived a need for treatment (63.8%). Attitudinal barriers were much more important than structural barriers to both initiating and continuing treatment. However, attitudinal barriers dominated for mild-moderate cases and structural barriers for severe cases. Perceived ineffectiveness of treatment was the most commonly reported reason for treatment drop-out (39.3%), followed by negative experiences with treatment providers (26.9% of respondents with severe disorders). Low perceived need and attitudinal barriers are the major barriers to seeking and staying in treatment among individuals with common mental disorders worldwide. Apart from targeting structural barriers, mainly in countries with poor resources, increasing population mental health literacy is an important endeavor worldwide.

Data on the migration of health-care workers: sources, uses, and challenges.
Diallo, Khassoum
2004-01-01
The migration of health workers within and between countries is a growing concern worldwide because of its impact on health systems in developing and developed countries alike. Policy decisions need to be made at the national, regional and international levels to manage more effectively this phenomenon, but those decisions will be effective and correctly implemented and evaluated only if they are based on adequate statistical data. Most statistics on the migration of health-care workers are neither complete nor fully comparable, and they are often underused, limited (because they often give only a broad description of the phenomena) and not as timely as required. There is also a conflict between the wide range of potential sources of data and the poor statistical evidence on the migration of health personnel. There are two major problems facing researchers who wish to provide evidence on this migration: the problems commonly faced when studying migration in general, such as definitional and comparability problems of "worker migrations" and those related to the specific movements of the health workforce. This paper presents information on the uses of statistics and those who use them, the strengths and limitations of the main data sources, and other challenges that need to be met to obtain good evidence on the migration of health workers. This paper also proposes methods to improve the collection, analysis, sharing, and use of statistics on the migration of health workers. PMID:15375450

The face-grafting techniques are innovative and highly complex, requiring well-defined organization of all the teams involved. Subsequent to the first report in France in 2005, there have been 17 facial allograft transplantations performed worldwide. We describe anaesthesia and postoperative management, and the problems encountered, during the course of seven facial composite tissue grafts performed between 2007 and 2011 in our hospital. The reasons for transplantation were ballistic trauma in four patients, extensive neurofibromatosis in two patients, and severe burns in one patient. Anaesthesia for this long procedure involves advanced planning for airway management, vascular access, technique of anaesthesia, and fluid management. Preparation and grafting phases were highly haemorrhagic (>one blood volume), requiring massive transfusion. Median (range) volumes given for packed red cell (PRC) and fresh-frozen plasma (FFP) were 64.2 ml kg(-1) (35.5-227.5) and 46.2 ml kg(-1) (6.3-173.7), respectively. Blood loss quantification was difficult because of diffuse bleeding to the drapes. The management of patients with neurofibromatosis or burns involving the whole face was more difficult and haemorrhagic than the patients with lower face transplantation. Average surgical duration was 19.1 h (15-28 h). Postoperative severe graft oedema was present in most patients. Most patients encountered complications in ICU, such as renal insufficiency, acute respiratory distress syndrome, and jugular thrombosis. Opportunistic bacterial infections were a feature during the postoperative period in these highly immunosuppressed patients.

In efforts to overcome an foreseeable energy crisis predicated on limited oil and gas supplies, reserves; economic variations facing the world, and of course the environmental side effects of fossil fuels, an urgent need for energy sources that provide sustainable, safe and economic supplies for the world is imperative. The current fossil fuel energy system must be improved to ensure a better and cleaner transportation future for the world. Despite the fact that the marine transportation sector consumes only 5% of global petroleum production; it is responsible for 15% of the world NO x and SO x emissions. These figures must be the engine that powers the scientific research worldwide to develop new solutions for a very old energy problem. In this paper, the most effective types of marine power plants were discussed. The history of the development of each type was presented first and the technical aspects were discussed second. Also, the fuel cells as a new type of power plants used in marine sector were briefed to give a complete overview of the past, present and future of the marine power plants development. Based on the increased worldwide concerns regarding harmful emissions, many researchers have introduced solutions to this problem, including the adoption of new cleaner fuels. This paper was guided using the same trend and by implementing the hydrogen as fuel for marine internal combustion engine, gas turbines, and fuel cells.

The health transition, global modernity and the crisis of traditional medicine: the Tibetan case.
Janes, C R
1999-06-01
The epidemiologic and demographic consequences of the health transition, coupled with worldwide pressures for health care reform according to neoliberal tenets, will create new opportunities, and well as new problems, for organized systems of indigenous medicine. Spiraling costs of biomedically-based health care, coupled with an increasing global burden of chronic, degenerative diseases and mental disorder, will produce significant incentives for the expansion of indigenous alternatives. Yet this expansion will be accompanied by pressures to rationalize and modernize health care services according to the structurally dominant scientific paradigm. Without concerted effort to maintain native epistemologies, indigenous medical systems face an inevitable slide into narrow herbal traditions and a loss of those elements of diagnosis and therapy which may be the most valuable and effective. Analyzing the case of Tibetan medicine and other Asian medical systems, I show how this process occurs and how it is resisted. I conclude by discussing the policy dimensions of this problem.
The problem of IVF cost in developing countries: has natural cycle IVF a place?
Shahin, Ahmed Y
2007-07-01
Infertility represents a national health problem in some African countries. Limited financial health resources in developing countries are a major obstacle facing infertility management. IVF is the definitive line of treatment for many couples. Stimulation cycles are associated with risks of ovarian hyperstimulation syndrome and multiple pregnancy. This study evaluates the client acceptability of stimulated versus natural cycle IVF among couples attending one infertility clinic, with respect to cost and pregnancy outcome. Of the patients who were indicated for IVF, 15% (16/107) cancelled, due mostly (12/16, 75%) to financial reasons. The majority of patients who completed their IVF treatment (82/91, 90.1%) felt the price of the medical service offered was high, and 68.1% (62/91) accepted the idea of having cheaper drugs with fewer side effects but with possibly lower chances of pregnancy. Natural cycle IVF has emerged as a potential option that might be suitable for patients worldwide, especially in developing countries.

Illicit drug abuse has crossed social, economic, and geographical borders, and remains one of the major health problems that modern society is facing worldwide. The role of multiple drug abuse as a basic for chromosome damage has been overlooked and it is important to determine its possible adverse health effects. This study aimed to compare the frequency of chromosomal damages between drug addicts and free drug controls. Cytogenetic study was obtained from 146 illicit drug-users and 200 free drug controls. Subjects were grouped into three categories depending on main drug of dependence. Cytogenetic studies on cultured lymphocytes showed an increase the frequency of chromosomal damages among addicts including opiate (5.89%), heroin (7.65%), and crystal (4.9%) when compared with drug free controls (1.45%). The frequency of chromosomal abnormalities was breaks, gaps, marker, and acentric, respectively. Our findings are also important as they are among the first to suggest here, illicit drug addiction continue to be significant public health problems in Iran.

Objectives There is a growing consensus worldwide that palliative care needs to be both more inclusive of conditions other than cancer and to improve. This paper explores some common challenges currently faced by professionals providing palliative care for patients with either cancer or dementia across five countries. Method One focus group (n = 7) and 67 interviews were conducted in 2012 across five countries: England, Germany, Italy, the Netherlands and Norway, with professionals from dementia, cancer and palliative care settings. Results The interviews revealed five common challenges faced across the five countries: communication difficulties (between services; and between professionals, and patients and their families); the variable extent of structural/functional integration of services; the difficulties in funding of palliative care services; problematic processes of care (boundaries, definitions, knowledge, skills and inclusiveness) and, finally, time constraints. Conclusion These are not problems distinct to palliative care, but they may have different origins and explanations compared to other areas of health care. This paper explored deeper themes hidden behind a discourse about barriers and facilitators to improving care. PMID:24131061
Patient support groups in the management of Wilson disease.
Graper, Mary L; Schilsky, Michael L
2017-01-01
Patient support groups serve an important function for those affected by a disease but especially for people with a rare disease. Because of the complexity of Wilson disease there are some unique and difficult problems faced by groups that advocate for these patients. We give a comparative overview of the differences between groups that support people with more common diseases and groups that serve the rare disease population. The history and current status of the Wilson Disease Association and other worldwide Wilson disease groups are described and information about other organizations that support Wilson disease in additional ways is explained. The specific challenges faced in the support of Wilson disease patients are outlined and possible solutions proposed. Drawing from experience in speaking with many patients, we discuss some of the most common questions that are asked by patients who are seeking a possible diagnosis or are already on treatment. There are many options for improving patient advocacy efforts in the future that we hope will be accomplished. © 2017 Elsevier B.V. All rights reserved.
[Ethical problems in organ transplantation].
Bosshard, Georg
2009-08-01
Since the early 1960s transplantation surgery has rapidly developed into a flagship technique of modern high-tech medicine with convincing therapeutic success. However, transplantation surgery also raises a number of serious ethical issues. The majority of solid organ transplants are procured from so-called brain-dead donors, i.e., from individuals with irreversible loss of all brain functions. This imposes the question whether and how the well-defined irreversible brain death can be equated with the death of an individual. The distribution of organs from brain-dead donors raises additional ethical questions and concerns. In the face of an increasing shortage of donor organs, what are the best criteria for setting priorities among the recipients? Is it urgency, need, or cost-effectiveness of the transplantation? And how can these parameters be appropriately defined? Moreover, as living organ donation (kidney, liver) becomes rife we are faced with the question of what voluntariness means in such exceptional conditions and how voluntariness can be adequately assessed. Finally, serious ethical concerns evolve from the so-called 'transplant tourism' and 'organ trafficking', accounting for approximately 5 to 10 % of all kidney transplantations world-wide.

Evidence of interdependencies of face and word processing mechanisms suggest possible links between reading problems and abnormal face processing. In two experiments we assessed such high-level visual deficits in people with a history of reading problems. Experiment 1 showed that people who were worse at face matching had greater reading problems. In experiment 2, matched dyslexic and typical readers were tested, and difficulties with face matching were consistently found to predict dyslexia over and above both novel-object matching as well as matching noise patterns that shared low-level visual properties with faces. Furthermore, ADHD measures could not account for face matching problems. We speculate that reading difficulties in dyslexia are partially caused by specific deficits in high-level visual processing, in particular for visual object categories such as faces and words with which people have extensive experience.

Botulinum neurotoxins are diverse proteins. They are currently represented by at least seven serotypes and more than 40 subtypes. New clostridial strains that produce novel neurotoxin variants are being identified with increasing frequency, which presents challenges when organizing the nomenclature surrounding these neurotoxins. Worldwide, researchers are faced with the possibility that toxins having identical sequences may be given different designations or novel toxins having unique sequences may be given the same designations on publication. In order to minimize these problems, an ad hoc committee consisting of over 20 researchers in the field of botulinum neurotoxin research was convened to discuss the clarification of the issues involved in botulinum neurotoxin nomenclature. This publication presents a historical overview of the issues and provides guidelines for botulinum neurotoxin subtype nomenclature in the future. PMID:28106761

Corrosion of metals is a serious and challenging problem faced worldwide by industry. Purified Leuconostoc mesenteroides exopolysaccharide (EPS) coatings, cast from aqueous solution, inhibited the corrosion of low-carbon steel as determined by electrochemical impedance spectroscopy (EIS). There were two different corrosion behaviors exhibited when EPS films from different strains were cast onto the steel. One EPS coating reacted immediately with the steel substrate to form an iron (III) oxide layer ("rust") during the drying process while another did not. The samples that did not flash corrode had higher corrosion inhibition and formed an iron (II) passivation layer during EIS testing that persisted after the cells were disassembled. Corrosion inhibition was strain-specific as polysaccharides with similar structure did not have the same corrosion potential.

Two of the most prevalent problems children facing worldwide are injuries and obesity. We conducted a systematic review of published studies that evaluated the effects of obesity on children with traumatic injuries. Six studies published between 2006 and 2014 were identified, comprising a total of 4594 children: 867 were obese and 3727 were not. Obese children were 25% more likely to have extremity fractures than nonobese children (p = 0.003), and their mortality rate was significantly higher at 4.7% versus 2.8% (p = 0.026). Our review showed that obese children were more likely to have extremity fractures and die of traumatic injuries than nonobese children. ©2016 Foundation Acta Paediatrica.

Child prostitution: global health burden, research needs, and interventions.
Willis, Brian M; Levy, Barry S
2002-04-20
Child prostitution is a significant global problem that has yet to receive appropriate medical and public health attention. Worldwide, an estimated 1 million children are forced into prostitution every year and the total number of prostituted children could be as high as 10 million. Inadequate data exist on the health problems faced by prostituted children, who are at high risk of infectious disease, pregnancy, mental illness, substance abuse, and violence. Child prostitution, like other forms of child sexual abuse, is not only a cause of death and high morbidity in millions of children, but also a gross violation of their rights and dignity. In this article we estimate morbidity and mortality among prostituted children, and propose research strategies and interventions to mitigate such health consequences. Our estimates underscore the need for health professionals to collaborate with individuals and organisations that provide direct services to prostituted children. Health professionals can help efforts to prevent child prostitution through identifying contributing factors, recording the magnitude and health effects of the problem, and assisting children who have escaped prostitution. They can also help governments, UN agencies, and non-governmental organisations (NGOs) to implement policies, laws, and programmes to prevent child prostitution and mitigate its effects on children's health.

The pattern and global burden of disease has evolved considerably over the last two decades, from primarily communicable, maternal, and perinatal causes to non-communicable disease (NCD). Cardiovascular disease (CVD) has become the single most important and largest cause of NCD deaths worldwide at over 50%. The World Health Organisation (WHO) estimates that 17.6 million people died of CVD worldwide in 2012. Proportionally, this accounts for an estimated 31.43% of global mortality, with ischaemic heart disease (IHD) accounting for approximately 7.4 million deaths, 13.2% of the total. IHD was also the greatest single cause of death in 2000, accounting for an estimated 6.0 million deaths. The global burden of CVD falls, principally, on the low and middle-income (LMI) countries, accounting for over 80% of CVD deaths. Individual populations face differing challenges and each population has unique health burdens, however, CVD remains one of the greatest health challenges both nationally and worldwide.

Craniofacial defects (CFD) are a significant healthcare problem worldwide. Understanding both the morphogenetic movements which underpin normal facial development, as well as the molecular factors which regulate these processes, forms the cornerstone of future diagnostic, and ultimately, preventative therapies. The soluble morphogen Sonic hedgehog (Shh), a vertebrate orthologue of Drosophila hedgehog, is a key signalling factor in the regulation of craniofacial skeleton development in vertebrates, operating within numerous tissue types in the craniofacial primordia to spatiotemporally regulate the formation of the face and jaws. This review will provide an overview of normal craniofacial skeleton development, and focus specifically on the known roles of Shh in regulating the development and progression of the first pharyngeal arch, which in turn gives rise to both the upper jaw (maxilla) and lower jaw (mandible).

Throughout 2005 and beyond, NASA will be faced with great challenges and even greater opportunities. Following a period of reevaluation, reinvention, and transformation, we will move rapidly forward to leverage new partnerships, approaches, and technologies that will enhance the way we do business. NASA's Scientific and Technical Information (STI) Program, which functions under the auspices of the Agency's Chief Information Officer (CIO), is an integral part of NASA's future. The program supports the Agency's missions to communicate scientific knowledge and understanding and to help transfer NASA's research and development (R&D) information to the aerospace and academic communities and to the public. The STI Program helps ensure that the Agency will remain at the leading edge of R&D by quickly and efficiently capturing and sharing NASA and worldwide STI to use for problem solving, awareness, and knowledge management and transfer.
The Janus Face of Stress on Reproduction: From Health to Disease
Zelena, Dóra
2015-01-01
Parenthood is a fundamental feature of all known life. However, infertility has been recognized as a public health issue worldwide. But even when the offspring are conceived, in utero problems can lead to immediate (abortion), early (birth), and late (adulthood) consequences. One of the most studied factors is stress. However, stress response is, per se, of adaptive nature allowing the organism to cope with challenges. Stressors lead to deterioration if one is faced with too long lasting, too many, and seemingly unsolvable situations. In stress adaptation the hypothalamus-pituitary-adrenocortical axis and the resulting glucocorticoid elevation are one of the most important mechanisms. At cellular level stress can be defined as an unbalance between production of free radicals and antioxidant defenses. Oxidative stress is widely accepted as an important pathogenic mechanism in different diseases including infertility. On the other hand, the goal of free radical production is to protect the cells from infectious entities. This review aims to summarize the negative and positive influence of stress on reproduction as a process leading to healthy progeny. Special emphasis was given to the balance at the level of the organism and cells. PMID:25945091

Natural disasters affected millions of people worldwide every year. Evaluation of disaster health and health response interventions is faced with several methodological challenges. This study aimed (1) to describe survivors' and health professionals' health, 30 months after a natural disaster using a web-based self-selected Internet sample survey designed and (2) to evaluate the health effects of disaster response interventions, in the present study with a focus on disaster radio. A web-based survey was used to conduct a cross-sectional study approximately 30 months after typhoon Haiyan. The GHQ-12, EQ-5D-3L, and EQ-VAS instruments were used in addition to study-specific questions. A self-selected Internet sample was recruited via Facebook. In total, 443 survivors, from what 73 were health professionals, participated in the study. The Haiyan typhoon caused both physical and mental health problems as well as social consequences for the survivors. Mental health problems were more frequently reported than physical injuries. Health professionals reported worse overall health and a higher frequency of mental health problems compared to other survivors. There were short-term and long-term physical, psychological, and social consequences for the survivors as a result of the Haiyan typhoon. Mental health problems were more frequently reported and lasted longer than physical problems. Health professionals deployed during the disaster reported worse health, especially concerning mental health problems. The survey used was found useful to describe health after disasters.

This study addresses the greatest concern facing the large-scale integration of wind, water, and solar (WWS) into a power grid: the high cost of avoiding load loss caused by WWS variability and uncertainty. It uses a new grid integration model and finds low-cost, no-load-loss, nonunique solutions to this problem on electrification of all US energy sectors (electricity, transportation, heating/cooling, and industry) while accounting for wind and solar time series data from a 3D global weather model that simulates extreme events and competition among wind turbines for available kinetic energy. Solutions are obtained by prioritizing storage for heat (in soil and water); cold (in ice and water); and electricity (in phase-change materials, pumped hydro, hydropower, and hydrogen), and using demand response. No natural gas, biofuels, nuclear power, or stationary batteries are needed. The resulting 2050-2055 US electricity social cost for a full system is much less than for fossil fuels. These results hold for many conditions, suggesting that low-cost, reliable 100% WWS systems should work many places worldwide.

Worldwide resources of arable land, water, groundwater, forest and expanding human habitat are under increasing pressure almost anywhere. Especially the non- industrialised countries with their rapidly increasing population are facing severe problems from natural catastrophes such as landslides, volcanic and seismic hazards, soil degradation and shortage of water or flooding. Geo-environmental research can help to identify the causes for these events, define the rehabilitation and can lead to early warning systems. Remote sensing adds considerable knowledge by providing a wide variety of sensors applied form airborne and space platforms, the data of which, once analysed, can provide completely new observations on natural risk areas. The UNESCO/IUGS sponsored GARS Program since 1984 is conducting- joint research with institutions in industrialised and developing countries. As of today, more than 40 institutes and individuals worldwide have joined the GARS- Program. Results of their research are among others contributions toLandslide assessment qVolcanic risk qCoastal hazards qDesertification processes q Space organisations and financing institutions serving developing nations are requested to help to deploy new sensors to monitor geo-dynamic processes, providing free and direct data reception in all parts of the world in order to allow national institutes to develop their own early warning capabilities.

Vascularized composite allotransplantation (VCA) to reconstruct complex centrally located facial defects and to restore vital functions in a 1-staged procedure has worldwide gained acceptance. Continuous long-term multidisciplinary follow-up of face transplant patients is mandatory for surveillance of the complications associated with the immunosuppressive regime and for functional assessment of the graft. In December 2011, our multidisciplinary team performed a digitally planned face transplant at the Ghent University Hospital, Belgium on a 55-year-old man with a large central facial defect after a high-energy ballistic injury. The patient was closely followed to assess functional recovery, immunosuppressive complications, overall well-being, and quality of life. Three years postoperatively, the patient and his family are very satisfied with the overall outcome, and social reintegration in the community is successful. Motor and sensory functions have recovered near normal. Infectious and medical complications have been serious but successfully managed. Immunosuppressive maintenance therapy consists of corticoids, tacrolimus, and mycophenolate mofetil in minimal doses. Epithetic reconstruction of both eyes gave a tremendous improvement on the overall aesthetic outcome. Despite serious complications during the first 12 months, multifunctional outcome in the first face transplant in Belgium (#19 worldwide) is successful. This should be attributed to the continuous and long-term multidisciplinary team approach. As only few reports of other face transplant patients on long-term follow-up are available, more data need to be collected and reported to further outweigh the risk benefit ratio of this life changing surgery.

Background In the UK, telephone triage in out-of-hours primary care is mostly managed by nurses, whereas GPs perform triage in Denmark. Aim To describe telephone contacts triaged to face-to-face contacts, GP-assessed relevance, and factors associated with triage to face-to-face contact. Design and setting A prospective observational study in Danish out-of-hours primary care, conducted from June 2010 to May 2011. Method Information on patients was collected from the electronic patient administration system and GPs completed electronic questionnaires about the contacts. The GPs conducting the face-to-face contacts assessed relevance of the triage to face-to-face contacts. The authors performed binomial regression analyses, calculating relative risk (RR) and 95% confidence intervals. Results In total, 59.2% of calls ended with a telephone consultation. Factors associated with triage to a face-to-face contact were: patient age >40 years (40–64: RR = 1.13; >64: RR = 1.34), persisting problem for 12–24 hours (RR = 1.15), severe problem (RR = 2.60), potentially severe problem (RR = 5.81), and non-severe problem (RR = 2.23). Face-to-face contacts were assessed as irrelevant for 12.7% of clinic consultations and 11.7% of home visits. A statistically significantly higher risk of irrelevant face-to-face contact was found for a persisting problem of >24 hours (RR = 1.25), contact on weekday nights (RR = 1.25), and contact <2 hours before the patient’s own GP’s opening time (RR = 1.80). Conclusion Around 12% of all face-to-face consultations in the study are assessed as irrelevant by GP colleagues, suggesting that GP triage is efficient. Knowledge of the factors influencing triage can provide better education for GPs, but future studies are needed to investigate other quality aspects of GP telephone triage. PMID:27432608

RTS2, or Remote Telescope System, 2nd Version, is an integrated package for remote telescope control under the Linux operating system. It is designed to run in fully autonomous mode, picking targets from a database table, storing image meta data to the database, processing images and storing their WCS coordinates in the database and offering Virtual-Observatory enabled access to them. It is currently running on various telescope setups world-wide. For control of devices from various manufacturers we developed an abstract device layer, enabling control of all possible combinations of mounts, CCDs, photometers, roof and cupola controllers. We describe the evolution of RTS2 from Python-based RTS to C and later C++ based RTS2, focusing on the problems we faced during development. The internal structure of RTS2, focusing on object layering, which is used to uniformly control various devices and provides uniform reporting layer, is also discussed.
Internal marketing and the antecedents of nurse satisfaction and loyalty.
Peltier, James W; Pointer, Lucille; Schibrowsky, John A
2008-01-01
Employee satisfaction and retention are critical issues that influence the success of any organization. Yet, one of the most critical problems facing the worldwide health care industry is the shortage of qualified nurses. Recent calls have been made within the traditional nursing literature for research that utilizes marketing and business models to better understand nurse satisfaction and retention. The purpose of this study is to develop scales that can be used to empirically test a model of the proposed antecedents of nurse job satisfaction and loyalty which have been used widely in the internal marketing and the relationship-marketing literature. Specifically, the study will investigate the degree to which structural bonding, social bonding, financial bonding activities, and quality of care impact how well nurses are satisfied with their job and their commitment to the organization. The results show that quality of care most impacted nurse satisfaction and loyalty, followed by structural, social, and financial bonds.
Ophthalmic public health; the way ahead.

Visual sciences have been progressing quickly in recent decades through globalization phenomenon. An enormous change has taken place in ocular health issues, however, there are various problems facing ophthalmic public health worldwide. In the previous years, the World Health Organization and the International Agency for the Prevention of Blindness in partnership launched the global initiative to eradicate avoidable blindness by the year 2020, VISION 2020 the Right to Sight. It has concentrated on the prevention of blindness disability and recognized a health issue-sight as a human right. In view of challenges ahead of visual sciences, close collaboration between international agencies at the global level to implement new strategies and monitor the progress will be mandatory. In these circumstances non-governmental organizations should not be neglected. World Sight Day 2012 would be a great opportunity to be a focus on importance of visual impairment as an important public health issue and discovering new challenges ahead.
Hajj stampede disaster, 2015: Reflections from the frontlines.
Khan, Anas A; Noji, Eric K
2016-01-01
The Hajj is an annual religious mass gathering that takes place in Makkah, Saudi Arabia. The complexity of its system is multidimensional, with religious, political, cultural, security, economic, communication, operational, and logistic unique challenges. This year, yet another stampede tragedy that caused around a 1,000 deaths and severe injuries, capturing worldwide media attention and exacerbating existing political tensions across the Gulf coasts was faced. Planning is important but the planning process is more important, requiring systematic analysis based on accurate collected and targeting root cause factors. Every year, the Hajj provides us with important knowledge and experience that will help preventing such events. This will only be possible if the initiative to extract all possible lessons learned are taken. The medical and public health community in Saudi Arabia must learn from other scientific fields where much more quantitative data-driven approach to identify problems and recommending solutions.
Women's health is a community issue.
Irvin, A
1997-01-01
When a member of the Community Life Project in Nigeria led a group of women in a discussion about HIV/AIDS, the women reported that they understood that condom use is the best means of protection but that they were unable to negotiate condom use with their husbands. Even if the women were economically independent, they would rather face the risk of HIV/AIDS than divorce. Thus, efforts to improve women's health have not generated much change on the local level. This can also be seen by the facts that current programs have failed to reduce the numbers of women dying from pregnancy-related causes each year, nearly 3000 women die from tuberculosis each day, women suffer occupational health risks, and domestic violence is an important determinant of health problems for women. Because women lack power in many societies, efforts to effect individual change may be blocked by a woman's particular circumstances. Thus, the involvement of entire communities is necessary to improve the conditions affecting women's health. Community-level discussions may open the door for couples to discuss sexuality and gender-based issues as well as safer sex behavior. Despite the important role they can play, women's community health groups face stiff challenges because of a lack of knowledge or training and because of the difficulty in overcoming gender-based discrimination. The Hesperian Foundation's publication, "Where Women Have No Doctor," is an excellent resource for understanding how poverty and gender issues affect women's health. The book contains practical information, promotes a model of community-based responses to problems with social origins, and shares experiences of grassroots groups world-wide.

The population problem: conceptions and misconceptions.
Berelson, B
1971-01-01
Only 1 in about 110 sex acts results in a conception and 1 in 270 in a live birth. Of all conceptions, 40% result in live births, 5% in stillbirths, and 55% never develop. 1/3 of all known conceptions ends in abortion, spontaneous or induced. It appears that the population problem depends on a small fraction of the potential. Misconceptions of the problem are corrected, and it is emphasized that while no social problem facing the U.S. would be easier with a larger population, demographic factors do not cause all of the other problems. Increasing numbers are not as important as the rate of increase (2% annually worldwide). Today's population problem has been caused by a decreased death rate, not an increased birthrate. There are 2 kinds of countries in the world today: those with a high standard of living and low fertility and those with a low standard of living and high fertility. Most of the uninformed women of the world would not choose to have large numbers of children if they had a choice. Population density is not a problem in itself. Experts disagree, but it is improbable that large numbers of people will die of starvation in the next few decades. Environmental deterioration is more the result of modern economic and technological practices than of demographic factors. Efforts at fertility control are not aimed at minorities in this country and elsewhere. The poor are discriminated against in access to family planning services and abortion. Moslems of developing countries have higher fertility rates than Roman Catholics in developed countries. There would be many social costs if the U.S. were to achieve zero population growth in the near future. The population problem has implications for the future quality of life.
A Survey on Sentiment Classification in Face Recognition

Qian, Jingyu
2018-01-01
Face recognition has been an important topic for both industry and academia for a long time. K-means clustering, autoencoder, and convolutional neural network, each representing a design idea for face recognition method, are three popular algorithms to deal with face recognition problems. It is worthwhile to summarize and compare these three different algorithms. This paper will focus on one specific face recognition problem-sentiment classification from images. Three different algorithms for sentiment classification problems will be summarized, including k-means clustering, autoencoder, and convolutional neural network. An experiment with the application of these algorithms on a specific dataset of human faces will be conducted to illustrate how these algorithms are applied and their accuracy. Finally, the three algorithms are compared based on the accuracy result.

The ornamental trade is a worldwide industry worth >15 billion USD with a problem of rampant product misidentification. Minimizing misidentification is critical in the face of overexploitation of species in the trade. We surveyed the peppermint shrimp ornamental marketplace in the southeastern USA, the most intense market for peppermint shrimps worldwide, to characterize the composition of species in the trade, reveal the extent of misidentification, and describe the population genetics of the true target species. Shrimps were bought from aquarium shops in FL, GA, SC, and NC. We demonstrated, contrary to popular belief (information from dealers), that the most heavily traded species in the market was Lysmata boggessi, an endemic species to the eastern Gulf of Mexico, and not Lysmata wurdemanni. Importantly, only when color pattern or genetic markers in conjunction with morphological traits were employed, was it was possible to unequivocally identify L. boggessi as the only species in the trade. The intensity of the market for peppermint shrimps in the USA has led to L. boggessi being the most traded species worldwide. Misidentification in the shrimp aquarium trade is accidental and involuntary, and is explained by remarkable similarity among congeneric species. Using sequences of the 16S-mt-DNA marker, we found no indication of population genetic structure in the endemic L. boggessi across 550 km of linear coast. Therefore, this species can be considered genetically homogeneous and a single fished stock. Still, we argue in favor of additional studies using more powerful markers (e.g., SNPs) capable of revealing genetic structure at a finer spatial-scale. Our results will help advance management and conservation policies in this lucrative yet understudied fishery. Future studies of other ornamental fisheries will benefit from using an integrative taxonomic approach, as we demonstrate here. PMID:28948100

Smoking is the main preventable public health problem particularly for youth worldwide. The aim of the present study was to determine the prevalence of smoking habits among students at secondary and high schools, and to compare the findings with those of a study conducted 15 years ago in the same area. In this cross-sectional study 6212 students (51.2% female; 48.8% male) were selected randomly from rural and urban areas in Samsun. All students completed a face-to-face questionnaire. The overall prevalence of smoking was 13.0% (male students, 18.1%; female students, 8.2%). The mean starting age of smoking was 14.1 ± 1.5 years. Prevalence of smoking was 15.7% in urban areas and 8.1% in rural areas. The most important factors for starting smoking were social group and families. Compared with a study conducted 15 years previously in the same area for male students, smoking prevalence was increased in rural, but decreased in urban areas. Smoking prevalence in students in Samsun was similar to that in a study conducted 15 years previously. It is important to use anti-smoking campaigns directly targeted at teenager and they should be fully informed of the harmful effects of smoking. © 2015 Japan Pediatric Society.
Amygdala hypoactivity to fearful faces in boys with conduct problems and callous-unemotional traits.
Jones, Alice P; Laurens, Kristin R; Herba, Catherine M; Barker, Gareth J; Viding, Essi

Although early-onset conduct problems predict both psychiatric and health problems in adult life, little research has been done to index neural correlates of conduct problems. Emerging research suggests that a subgroup of children with conduct problems and elevated levels of callous-unemotional traits may be genetically vulnerable to manifesting disturbances in neural reactivity to emotional stimuli indexing distress. Using functional MRI, the authors evaluated differences in neural response to emotional stimuli between boys with conduct problems and elevated levels of callous-unemotional traits and comparison boys. Seventeen boys with conduct problems and elevated levels of callous-unemotional traits and 13 comparison boys of equivalent age (mean=11 years) and IQ (mean=100) viewed blocked presentations of fearful and neutral faces. For each face, participants distinguished the sex of the face via manual response. Relative to the comparison group, boys with conduct problems and elevated levels of callous-unemotional traits manifested lesser right amygdala activity to fearful faces. This finding is in line with data from studies of adults with antisocial behavior and callous-unemotional traits (i.e., psychopaths), as well as from a recent study of adolescents with callous-unemotional traits, and suggests that the neural substrates of emotional impairment associated with callous-unemotional antisocial behavior are already present in childhood.

From time to time, the maintenance works become more challenging due to construction of new building and also aging of the existing buildings. University buildings without any exception require proper maintenance services to support their function requirements and this can be considered as major responsibilities to be fulfilled by the maintenance department in the universities. Maintenance department specifically will face various kinds of problems in their operation works and thus this might influence the maintenance work operations itself. This study purposely to identify the common problem facing by the maintenance department and also to examine the current status of the maintenance department. In addition, this study would also propose any suitable approach that could be implemented to overcome the problem facing by the maintenance department. To achieve the objectives of this study, a combination of deep literature study and carrying out a survey is necessary. Literature study aimed to obtain deeper information about this study, meanwhile a survey aimed at identifying the common problem facing by the maintenance department and also to provide the information of the maintenance department’s organization. Several methods will be used in analyzing the data obtained through the survey, including Microsoft Office Excel and also using mean index formula. This study has identified three categories of problem in the maintenance department, which are management problems, human resource problem, and technical problems. Following the findings, several solutions being proposed which can be implemented as the solution to the problem facing. These suggestions have the potential to improve the maintenance department work efficiency, thus could help to increase the department productivity.

Compared with male surgeons, women have less success advancing their careers and are underrepresented in leadership positions in surgery. The purpose of this study is to identify the qualifications necessary to become leaders in surgery and the career barriers faced by women surgeons in various cultural environments. A survey was performed with women surgeons in Japan, USA, Finland, and Hong Kong, China, to assess various barriers faced by women surgeons in the respective countries. To develop appropriate survey tool, a preliminary questionnaire was distributed to leaders in surgery and also in various organizations worldwide. The response rate was 23 % with 225 of 964 survey returned. Japanese women surgeons identify lacked family support as impeding a successful surgical career. US women surgeons feel more latent gender discrimination. Finnish women surgeons are less likely to need to sacrifice work-life balance, when holding leadership positions. Women surgeons worldwide are highly motivated to develop their career and agree the percentage of women surgeons in leadership positions should be increased. Women surgeons in different countries perceive different challenges. We must develop strategies and should not hesitate to negotiate to overcome these issues to reach leadership positions in surgery. This may be accomplished through networking worldwide to improve current conditions and obstacles.
Preparing for a face transplant: development of a comprehensive nursing educational program.

To date, more than 30 face transplants have been performed worldwide. This innovative procedure has restored the functional and aesthetic aspects of the face in patients with cancer, congenital, and trauma-related deformities where the results of traditional reconstructive surgery have been deficient. The importance of nursing involvement in the care of these patients is undeniable; however, little has been published about how to properly prepare a nursing department to undertake such an important role. Although the care of patients undergoing face transplants has many similarities to the care of patients undergoing traditional head and neck flap procedures, patients undergoing face transplant provide unique challenges, including immunosuppression, allograft rejection, communication impairment, and psychosocial needs. Staff at New York University's Langone Medical Center have devised a specific plan of action to properly inform, educate, and prepare the nursing staff for this exciting endeavor.
Semisupervised kernel marginal Fisher analysis for face recognition.
Wang, Ziqiang; Sun, Xia; Sun, Lijun; Huang, Yuchun
2013-01-01
Dimensionality reduction is a key problem in face recognition due to the high-dimensionality of face image. To effectively cope with this problem, a novel dimensionality reduction algorithm called semisupervised kernel marginal Fisher analysis (SKMFA) for face recognition is proposed in this paper. SKMFA can make use of both labelled and unlabeled samples to learn the projection matrix for nonlinear dimensionality reduction. Meanwhile, it can successfully avoid the singularity problem by not calculating the matrix inverse. In addition, in order to make the nonlinear structure captured by the data-dependent kernel consistent with the intrinsic manifold structure, a manifold adaptive nonparameter kernel is incorporated into the learning process of SKMFA. Experimental results on three face image databases demonstrate the effectiveness of our proposed algorithm.

Managing comorbidities in COPD
Hillas, Georgios; Perlikos, Fotis; Tsiligianni, Ioanna; Tzanakis, Nikolaos
2015-01-01
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Age and smoking are common risk factors for COPD and other illnesses, often leading COPD patients to demonstrate multiple coexisting comorbidities. COPD exacerbations and comorbidities contribute to the overall severity in individual patients. Clinical trials investigating the treatment of COPD routinely exclude patients with multiple comorbidities or advanced age. Clinical practice guidelines for a specific disease do not usually address comorbidities in their recommendations. However, the management and the medical intervention in COPD patients with comorbidities need a holistic approach that is not clearly established worldwide. This holistic approach should include the specific burden of each comorbidity in the COPD severity classification scale. Further, the pharmacological and nonpharmacological management should also include optimal interventions and risk factor modifications simultaneously for all diseases. All health care specialists in COPD management need to work together with professionals specialized in the management of the other major chronic diseases in order to provide a multidisciplinary approach to COPD patients with multiple diseases. In this review, we focus on the major comorbidities that affect COPD patients. We present an overview of the problems faced, the reasons and risk factors for the most commonly encountered comorbidities, and the burden on health care costs. We also provide a rationale for approaching the therapeutic options of the COPD patient afflicted by comorbidity. PMID:25609943
Multi-Dimensional, Non-Pyrolyzing Ablation Test Problems
NASA Technical Reports Server (NTRS)
Risch, Tim; Kostyk, Chris
2016-01-01
Non-pyrolyzingcarbonaceous materials represent a class of candidate material for hypersonic vehicle components providing both structural and thermal protection system capabilities. Two problems relevant to this technology are presented. The first considers the one-dimensional ablation of a carbon material subject to convective heating. The second considers two-dimensional conduction in a rectangular block subject to radiative heating. Surface thermochemistry for both problems includes finite-rate surface kinetics at low temperatures, diffusion limited ablation at intermediate temperatures, and vaporization at high temperatures. The first problem requires the solution of both the steady-state thermal profile with respect to the ablating surface and the transient thermal history for a one-dimensional ablating planar slab with temperature-dependent material properties. The slab front face is convectively heated and also reradiates to a room temperature environment. The back face is adiabatic. The steady-state temperature profile and steady-state mass loss rate should be predicted. Time-dependent front and back face temperature, surface recession and recession rate along with the final temperature profile should be predicted for the time-dependent solution. The second problem requires the solution for the transient temperature history for an ablating, two-dimensional rectangular solid with anisotropic, temperature-dependent thermal properties. The front face is radiatively heated, convectively cooled, and also reradiates to a room temperature environment. The back face and sidewalls are adiabatic. The solution should include the following 9 items: final surface recession profile, time-dependent temperature history of both the front face and back face at both the centerline and sidewall, as well as the time-dependent surface recession and recession rate on the front face at both the centerline and sidewall. The results of the problems from all submitters will be collected, summarized, and presented at a later conference.
Surviving ICU: Stories of recovery.
Ewens, Beverley A; Hendricks, Joyce M; Sundin, Deborah
2018-02-28
The aim of this study was to investigate stories of recovery through the lens of intensive care unit (ICU) survivors. Survival from ICUs is increasing, as are associated physical and psychological complications. Despite the significant impact on survivors, there is inadequate support provision in Australia and world-wide for this population. An interpretive biographical approach of intensive care survivors' experiences of recovery. Data were collected during 2014-2015 from diaries, face to face interviews, memos and field notes. Six participants diarized for 3 months commencing 2 months after hospital discharge. At 5 months, participants were interviewed about the content of their diaries and symbols and signifiers in them to create a shared meaning. Analysis of diaries and interviews were undertaken using two frameworks to identify themes throughout participants' stories and provides a unique portrait of recovery through their individual lens. Participants considered their lives had irreparably changed and yet felt unsupported by a healthcare system that had "saved" them. This view through their lens identified turmoil, which existed between their surface and inner worlds as they struggled to conform to what recovery "should be". The novel biographical methods provided a safe and creative way to reveal survivors' inner thoughts and feelings. Participants' considered creating their stories supported their recovery process and in particular enabled them to reflect on their progress. Findings from this study may lead to increased awareness among health care providers about problems survivors face and improved support services more broadly, based on frameworks appropriate for this population. © 2018 John Wiley & Sons Ltd.

In law enforcement and security applications, the acquisition of face images is critical in producing key trace evidence for the successful identification of potential threats. However, face recognition (FR) for face images captured using different camera sensors, and under variable illumination conditions, and expressions is very challenging. In this paper, we investigate the advantages and limitations of the heterogeneous problem of matching ultra violet (from 100 nm to 400 nm in wavelength) or UV, face images against their visible (VIS) counterparts, when all face images are captured under controlled conditions. The contributions of our work are three-fold; (i) We used a camera sensor designed with the capability to acquire UV images at short-ranges, and generated a dual-band (VIS and UV) database that is composed of multiple, full frontal, face images of 50 subjects. Two sessions were collected that span over the period of 2 months. (ii) For each dataset, we determined which set of face image pre-processing algorithms are more suitable for face matching, and, finally, (iii) we determined which FR algorithm better matches cross-band face images, resulting in high rank-1 identification rates. Experimental results show that our cross spectral matching (the heterogeneous problem, where gallery and probe sets consist of face images acquired in different spectral bands) algorithms achieve sufficient identification performance. However, we also conclude that the problem under study, is very challenging, and it requires further investigation to address real-world law enforcement or military applications. To the best of our knowledge, this is first time in the open literature the problem of cross-spectral matching of UV against VIS band face images is being investigated.
Memory for angry faces, impulsivity, and problematic behavior in adolescence.
d'Acremont, Mathieu; Van der Linden, Martial
2007-04-01
Research has shown that cognitive processes like the attribution of hostile intention or angry emotion to others contribute to the development and maintenance of conduct problems. However, the role of memory has been understudied in comparison with attribution biases. The aim of this study was thus to test if a memory bias for angry faces was related to conduct problems in youth. Adolescents from a junior secondary school were presented with angry and happy faces and were later asked to recognize the same faces with a neutral expression. They also completed an impulsivity questionnaire. A teacher assessed their behavior. The results showed that a better recognition of angry faces than happy faces predicted conduct problems and hyperactivity/inattention as reported by the teacher. The memory bias effect was more pronounced for impulsive adolescents. It is suggested that a memory bias for angry faces favors disruptive behavior but that a good ability to control impulses may moderate the negative impact of this bias.

Large distributed computing collaborations, such as the Worldwide LHC Computing Grid (WLCG), face many issues when it comes to providing a working grid environment for their users. One of these is exchanging tickets between various ticketing systems in use by grid collaborations. Ticket systems such as Footprints, RT, Remedy, and ServiceNow all have different schema that must be addressed in order to provide a reliable exchange of information between support entities and users in different grid environments. To combat this problem, OSG Operations has created a ticket synchronization interface called GOC-TX that relies on web services instead of error-prone email parsing methods of the past. Synchronizing tickets between different ticketing systems allows any user or support entity to work on a ticket in their home environment, thus providing a familiar and comfortable place to provide updates without having to learn another ticketing system. The interface is built in a way that it is generic enough that it can be customized for nearly any ticketing system with a web-service interface with only minor changes. This allows us to be flexible and rapidly bring new ticket synchronization online. Synchronization can be triggered by different methods including mail, web services interface, and active messaging. GOC-TX currently interfaces with Global Grid User Support (GGUS) for WLCG, Remedy at Brookhaven National Lab (BNL), and Request Tracker (RT) at the Virtual Data Toolkit (VDT).

Recent literature shows that facial attributes, i.e., contextual facial information, can be beneficial for improving the performance of real-world applications, such as face verification, face recognition, and image search. Examples of face attributes include gender, skin color, facial hair, etc. How to robustly obtain these facial attributes (traits) is still an open problem, especially in the presence of the challenges of real-world environments: non-uniform illumination conditions, arbitrary occlusions, motion blur and background clutter. What makes this problem even more difficult is the enormous variability presented by the same subject, due to arbitrary face scales, head poses, and facial expressions. In this paper, we focus on the problem of facial trait classification in real-world face videos. We have developed a fully automatic hierarchical and probabilistic framework that models the collective set of frame class distributions and feature spatial information over a video sequence. The experiments are conducted on a large real-world face video database that we have collected, labelled and made publicly available. The proposed method is flexible enough to be applied to any facial classification problem. Experiments on a large, real-world video database McGillFaces [1] of 18,000 video frames reveal that the proposed framework outperforms alternative approaches, by up to 16.96 and 10.13%, for the facial attributes of gender and facial hair, respectively.

Commentary: Science scandal or ethics scandal? Olivieri redux.
Schafer, Arthur
2007-02-01
Dr. Nancy Olivieri has become an icon of research integrity for her insistence on publishing adverse data about a drug she was investigating. She has been celebrated world-wide as a hero of biomedical ethics for her bravery in disclosing potential dangers to research subjects, in the face of both drug company threats and coercive pressures from her hospital and university. Like so many other 'whistle-blowers' however, she now faces both personal vilification and disturbing accusations of scientific error. The case against Olivieri is assessed and found to be baseless.

Worldwide, there are enormous inequities in cancer control that cause poor outcomes among patients with cancer who live in low- and middle-income countries (LMICs). One of the biggest challenges that oncology faces today is how to increase patient access to expensive, but life-saving, therapies in LMICs. Access to cancer medications in LMICs is a major problem, especially in recent years, as the costs of these therapies continue to rise exponentially. One mechanism available to LMICs to improve access to cancer medications allows a country to pursue a compulsory license for a given drug. Here, we will review how the legal framework in the World Trade Organization's Trade-Related Aspects of Intellectual Property Rights Agreement and the Doha Declaration supports countries to circumvent patent laws and acquire compulsory licenses for essential medicines. We will also discuss the current and future role of compulsory licenses in oncology and how compulsory licenses may improve access to cancer drugs in LMICs. PMID:28717715

Well-being of cancer patients and survivors is a challenge worldwide, considering the often chronic nature of the disease. Today, a large number of initiatives, products and services are available that aim to provide strategies to face the challenge of well-being in cancer patients; nevertheless the proposed solutions are often non-sustainable, costly, unavailable to those in need, and less well-received by patients. These challenges were considered in designing FORECAST, a cloud-based personalized intelligent virtual coaching platform for improving the well-being of cancer patients. Personalized coaching for cancer patients focuses on physical, mental, and emotional concerns, which FORECAST is able to identify. Cancer patients can benefit from coaching that addresses their emotional problems, helps them focus on their goals, and supports them in coping with their disease-related stressors. Personalized coaching in FORECAST offers support, encouragement, motivation, confidence, and hope and is a valuable tool for the wellbeing of a patient.
U.N.: AIDS likely to kill half of teens in worst-hit nations.
In the report of the Joint UN Programme on HIV/AIDS (UNAIDS) released on June 27, 2000, it is projected that AIDS is expected to kill half of the teenagers in some African nations, devastating economies and societies. Moreover, the UNAIDS estimated that the virus has killed 19 million people worldwide; that more than 13 million children have been orphaned; that in 16 sub-Saharan countries more than one-tenth of the population aged 15-49 is infected with HIV; and that in 7 of these countries at least one-fifth of the population is infected. Peter Piot, head of UNAIDS believes that legacy apartheid and governmental disregard of the problem are reasons for the AIDS epidemic in southern Africa. In view of this, the report urgently underscores the need for government leaders to face the crisis head on, engaging all sectors of society in the battle against the epidemic. A number of prevention initiatives are discussed and studies are cited regarding success of such AIDS-preventive strategies.

While medical ethics place a high value on providing truthful information to patients, disclosure practices are far from being the norm in many countries. Transmitting bad news still remains a big problem that health care professionals face in their every day clinical practice. Through the review of relevant literature, an attempt to examine the trends in this issue worldwide will be made. Various electronic databases were searched by the authors and through systematic selection 51 scientific articles were identified that this literature review is based on. There are many parameters that lead to the concealment of truth. Factors related to doctors, patients and their close environment, still maintain a strong resistance against disclosure of diagnosis and prognosis in terminally ill patients, while cultural influences lead to different approaches in various countries. Withholding the truth is mainly based in the fear of causing despair to patients. However, fostering a spurious hope, hides the danger of its' total loss, while it can disturb patient-doctor relationship.
A review of cyberbullying legislation in Qatar: Considerations for policy makers and educators.
Foody, Mairéad; Samara, Muthanna; El Asam, Aiman; Morsi, Hisham; Khattab, Azhar
Cyberbullying is a worldwide problem affecting mental health, education, safety and general well-being for individuals across the globe. Despite the widespread availability of the Internet, research into prevalence rates of cyberbullying in Qatar is lacking and legislating for the crime has been slow to develop. Recently there have been some positive initiatives in the country such as a Cybercrime Prevention Law, the development of a National ICT Strategy, and a website detailing safe practice guidelines for Internet usage. However, the implementation and usage of these initiatives are still limited and there is a lack of awareness of cyberbullying in Qatar. As a result, the risk factors and consequences among school-aged children are unknown. The current paper presents an evaluation of the legislative and public policy solutions to cyberbullying available in Qatar, and outlines the critical challenges that could potentially face educators in shaping best practice guidelines for the future.

Scombroid poisoning: mini-review with case histories.
Russell, F E; Maretić, Z
1986-01-01
Scombroid poisoning has become an almost world-wide medical problem. It is probably the most common cause of fish poisoning, although frequently misdiagnosed as "Salmonella infection'. While there remains some question as to the definitive etiology, there is little doubt that the poisoning is caused by the ingestion of certain mackerel-like fishes whose tissues have undergone a number of changes provoked by bacteria, and involving the conversion of histidine to histamine, potentiated by diamines. Improper storage of the fishes, usually at temperatures above 20 degrees C, appears to be the most important predisposing factor. The organisms most commonly involved are Proteus sp., Clostridium sp., Escherichia sp., Salmonella sp. and Shigella sp. Twenty-five cases of scombroid poisoning are presented. The clinical manifestations were very similar in most cases, consisting of: alterations in taste; anxiety; hyperemia, particularly of the face and neck; nausea; pruritus; headache; certain other symptoms and signs. Most patients responded to antihistamitics, and all cases were self-limiting.
Translation and validation of the Self-care of Heart Failure Index into Persian.
Siabani, Soraya; Leeder, Stephen R; Davidson, Patricia M; Najafi, Farid; Hamzeh, Behrooz; Solimani, Akram; Siahbani, Sara; Driscoll, Tim
2014-01-01
Chronic heart failure (CHF) is a common burdensome health problem worldwide. Self-care improves outcomes in patients with CHF. The Self-care of Heart Failure Index (SCHFI) is a well-known scale for assessing self-care. A reliable, valid, and culturally acceptable instrument is needed to develop and test self-care interventions in Iran. We sought to translate and validate the Persian version of SCHFI v 6.2 (pSCHFI). We translated the SCHFI into Persian (pSCHFI) using standardized methods. The reliability was evaluated by assessing Cronbach's α coefficient. Expert opinion, discussion with patients, and confirmatory factor analysis were used to assess face validity, content validity, and construct validity, respectively. The analysis, using 184 participants, showed acceptable internal consistency and construct validity for the 3 subscales of pSCHFI-self-care maintenance, self-care management, and self-care self-confidence. The pSCHFI is a valid instrument with an acceptable reliability for evaluating self-care in Persian patients with heart failure.
Teamwork and communication: an effective approach to patient safety.
Mujumdar, Sandhya; Santos, Diana
2014-01-01
Teamwork and communication failures are leading causes of patient safety incidents in health care. Though health care providers must work in teams, they are not well-trained in teamwork and communication skills. Health care faces the problems of differences in communication styles, communication failures and poor teamwork. There is enough evidence in the literature to show that communication failure is detrimental to patient safety. It is estimated that 80% of serious medical errors worldwide take place because of miscommunication between medical providers. NUH recognizes that effective communication and teamwork are essential in the delivery of high quality safe patient care, especially in a complex organization. NUH is a good example, where there is a rich mix of nationalities and races, in staff and in patients, and there is a rapidly expanding care environment. NUH had to overcome these challenges by adopting a multi-pronged approach. The trials and tribulations of NUH in this journey were worthwhile as the patient safety climate survey scores improved over the years.
Broadening Participation in the Sciences within and from Africa: Purpose, Challenges, and Prospects

Many of Africa’s challenges have scientific solutions, but there are fewer individuals engaged in scientific activity per capita on this continent than on any other. Only a handful of African scientists use their skills to capacity or are leaders in their disciplines. Underrepresentation of Africans in scientific practice, discourse, and decision making reduces the richness of intellectual contributions toward hard problems worldwide. This essay outlines challenges faced by teacher-scholars from sub-Saharan Africa as we build scientific expertise. Access to tertiary-level science is difficult and uneven across Africa, and the quality of training available varies from top-range to inadequate. Access to science higher education needs to increase, particularly for female students, first-generation literates, and rural populations. We make suggestions for collaborative initiatives involving stakeholders outside Africa and/or outside academia that could extend educational opportunities available to African students and increase the chance that Africa-based expertise is globally available.

Strategies and Methodologies for Developing Microbial Detoxification Systems to Mitigate Mycotoxins
Zhu, Yan; Hassan, Yousef I.; Lepp, Dion; Shao, Suqin; Zhou, Ting
2017-01-01
Mycotoxins, the secondary metabolites of mycotoxigenic fungi, have been found in almost all agricultural commodities worldwide, causing enormous economic losses in livestock production and severe human health problems. Compared to traditional physical adsorption and chemical reactions, interest in biological detoxification methods that are environmentally sound, safe and highly efficient has seen a significant increase in recent years. However, researchers in this field have been facing tremendous unexpected challenges and are eager to find solutions. This review summarizes and assesses the research strategies and methodologies in each phase of the development of microbiological solutions for mycotoxin mitigation. These include screening of functional microbial consortia from natural samples, isolation and identification of single colonies with biotransformation activity, investigation of the physiological characteristics of isolated strains, identification and assessment of the toxicities of biotransformation products, purification of functional enzymes and the application of mycotoxin decontamination to feed/food production. A full understanding and appropriate application of this tool box should be helpful towards the development of novel microbiological solutions on mycotoxin detoxification. PMID:28387743

This study presents evidence that cyberbullying victimization relates to internalizing, externalizing, and substance use problems in adolescents and that the frequency of family dinners attenuate these associations. To examine the unique association between cyberbullying victimization and adolescent mental health (after controlling differences in involvement in traditional, face-to-face bullying) and to explore the potential moderating role of family contact in this association. This cross-sectional, observational study used survey data on 18,834 students (aged 12-18 years) from 49 schools in a Midwestern US state. Logistic regression analysis tested associations between cyberbullying victimization and the likelihood of mental health and substance use problems. Negative binomial regression analysis tested direct and synergistic contributions of cyberbullying victimization and family dinners on the rates of mental health and substance use problems. Frequency of cyberbullying victimization during the previous 12 months; victimization by traditional (face-to-face) bullying; and perpetration of traditional bullying. Five internalizing mental health problems (anxiety, depression, self-harm, suicide ideation, and suicide attempt), 2 externalizing problems (fighting and vandalism), and 4 substance use problems (frequent alcohol use, frequent binge drinking, prescription drug misuse, and over-the-counter drug misuse). About one-fifth (18.6%) of the sample experienced cyberbullying during the previous 12 months. The frequency of cyberbullying positively related to all 11 internalizing, externalizing, and substance use problems (odds ratios from 2.6 [95% CI, 1.7-3.8] to 4.5 [95% CI, 3.0-6.6]). However, victimization related more closely to rates of problems in adolescents that had fewer family dinners. Cyberbullying relates to mental health and substance use problems in adolescents, even after their involvement in face-to-face bullying is taken into account. Although correlational, these results suggest that family dinners (ie, family contact and communication) are beneficial to adolescent mental health and may help protect adolescents from the harmful consequences of cyberbullying.

This study examines the association of the reporting of pain during intercourse in the postpartum period with mode of delivery, and describes women's reports of pain during intercourse and their health care seeking behavior over a period of 40 days-6 months postpartum. A cross-sectional study recruited women in their 2nd and 3rd trimester of pregnancy from private obstetric clinics affiliated with 18 hospitals in two regions of Lebanon. Face-to-face interviews using a structured questionnaire were conducted at the women's homes from 40 days to 6 months postpartum. Verbal, informed consent was obtained from all women participating in the study before the interview. In a sample of 238 women, 67% reported experiencing pain during intercourse postpartum and 72.3% did not seek care. Women having a cesarean delivery (1.96; CI (1.29-2.63)), who were primiparous (OR=2.44; CI (2.05-2.83)) and residing in the Mount Lebanon region (OR=1.25; CI (1.09-1.40)) were significantly more likely to report pain during intercourse postpartum. Cesarean births may increase the chances of reporting of pain during intercourse postpartum among primiparous women. Given that the increasing cesarean section rates worldwide are perceived to be protective of women's sexual health, prenatal and postpartum care need to address women's sexual health problems.

Young adult couples' decision making regarding emergency contraceptive pills.
Beaulieu, Richard; Kools, Susan M; Kennedy, Holly Powell; Humphreys, Janice
2011-03-01
Unintended pregnancy is a significant public health problem among young people worldwide. The purpose of this study was to explore and better understand the reasons for the apparent underuse of emergency contraceptive pills (ECP) in young people in coupled relationships. THEORETICAL RATIONAL: In postmodern explications of grounded theory, social construction of realities and the influence of subjectivities on the meanings of experiences lead to the development of partial truths that may change with time, context, and situation. Grounded theory methods guided semi-structured face-to-face interviews and data analysis. Twenty-two couples aged 18 to 25 years old were recruited through public notices. Four salient and interrelated conditions were constructed to help explain the complexities involved in young couples decision making regarding ECP use: (a) the shifting locus of responsibility for contraceptive decision making: in a perfect world versus biological reality; (b) relationship power: control-vulnerability continuum; (c) a woman's autonomy over her own body; and (d) conflicting views on ECP. Healthcare professionals whose practice includes young people need to be aware of possible couple dynamics when discussing contraception. Clients in supportive relationships should be encouraged to engage in open communication with their partners about their contraception needs, including possible ECP use. The results of this study contribute to the body of knowledge with regard to decision making related to ECP use in young adults. © 2011 Sigma Theta Tau International.

Biological invasions occur worldwide, and have been the object of ecological and socio-economic research for decades. However, the manner in which different stakeholder groups identify the problems associated with invasive species and confront invasive species management under different policies remains poorly understood. In this study, we conducted an econometric analysis of the social factors influencing willingness to pay for invasive alien species management under two different regimes: eradication and prevention in the Doñana Natural Protected Area (SW Spain). Controlling for the participation of local residents, tourists and conservationists, email and face-to-face questionnaires were conducted. Results indicated that respondents were more willing to pay for eradication than prevention; and public support for invasive alien species management was influenced by an individual's knowledge and perception of invasive alien species, active interest in nature, and socio-demographic attributes. We concluded that invasive alien species management research should confront the challenges to engage stakeholders and accept any tradeoffs necessary to modify different conservation policies to ensure effective management is implemented. Finally, our willingness to pay estimates suggest the Department of Environment of Andalusian Government has suitable social support to meet the budgetary expenditures required for invasive alien species plans and adequate resources to justify an increase in the invasive alien species management budget.

Because of the growth of the older population and the prevalence of chronic diseases, home care services (HCS) have become an important aspect of healthcare worldwide. However, various difficulties and deficiencies are present in the provision of these recently implemented services in Turkey. Modifications to home healthcare services are in progress. Physicians have an active role in home healthcare services. The present study was performed to examine physicians' attitudes toward this service in detail. Twenty-six physicians who provide home healthcare services in the city of Ankara were included in the study. We conducted in-depth, semi-structured, face-to-face interviews. The interviews were audio-recorded, transcribed, and qualitatively analysed. Most physicians thought that home care could be provided to patients who are bedridden, are very old, have a chronic disease, have problems leaving the house, or do not have family support. They also expressed displeasure about the abuse of services and discordance of organization between hospitals and primary care centres. They noted that real circumstances in practice were not compatible with regulations and that cooperation and coordination between departments are necessary and important. The current study underlines physicians' interest in and support of the home care system, which has various drawbacks and limitations. Legislation needs to be further changed to improve the quality of service and eliminate deficiencies in home healthcare.

Biological invasions occur worldwide, and have been the object of ecological and socio-economic research for decades. However, the manner in which different stakeholder groups identify the problems associated with invasive species and confront invasive species management under different policies remains poorly understood. In this study, we conducted an econometric analysis of the social factors influencing willingness to pay for invasive alien species management under two different regimes: eradication and prevention in the Doñana Natural Protected Area (SW Spain). Controlling for the participation of local residents, tourists and conservationists, email and face-to-face questionnaires were conducted. Results indicated that respondents were more willing to pay for eradication than prevention; and public support for invasive alien species management was influenced by an individual's knowledge and perception of invasive alien species, active interest in nature, and socio-demographic attributes. We concluded that invasive alien species management research should confront the challenges to engage stakeholders and accept any tradeoffs necessary to modify different conservation policies to ensure effective management is implemented. Finally, our willingness to pay estimates suggest the Department of Environment of Andalusian Government has suitable social support to meet the budgetary expenditures required for invasive alien species plans and adequate resources to justify an increase in the invasive alien species management budget.

Pose-Invariant Face Recognition via RGB-D Images.
Sang, Gaoli; Li, Jing; Zhao, Qijun
2016-01-01
Three-dimensional (3D) face models can intrinsically handle large pose face recognition problem. In this paper, we propose a novel pose-invariant face recognition method via RGB-D images. By employing depth, our method is able to handle self-occlusion and deformation, both of which are challenging problems in two-dimensional (2D) face recognition. Texture images in the gallery can be rendered to the same view as the probe via depth. Meanwhile, depth is also used for similarity measure via frontalization and symmetric filling. Finally, both texture and depth contribute to the final identity estimation. Experiments on Bosphorus, CurtinFaces, Eurecom, and Kiwi databases demonstrate that the additional depth information has improved the performance of face recognition with large pose variations and under even more challenging conditions.

An improved classifier based on the nearest feature plane (NFP), called the centre-based restricted nearest feature plane with the angle (RNFPA) classifier, is proposed for the face recognition problems here. The famous NFP uses the geometrical information of samples to increase the number of training samples, but it increases the computation complexity and it also has an inaccuracy problem coursed by the extended feature plane. To solve the above problems, RNFPA exploits a centre-based feature plane and utilizes a threshold of angle to restrict extended feature space. By choosing the appropriate angle threshold, RNFPA can improve the performance and decrease computation complexity. Experiments in the AT&T face database, AR face database and FERET face database are used to evaluate the proposed classifier. Compared with the original NFP classifier, the nearest feature line (NFL) classifier, the nearest neighbour (NN) classifier and some other improved NFP classifiers, the proposed one achieves competitive performance.

Active appearance model (AAM) is one of the most popular model-based approaches that have been extensively used to extract features by highly accurate modeling of human faces under various physical and environmental circumstances. However, in such active appearance model, fitting the model with original image is a challenging task. State of the art shows that optimization method is applicable to resolve this problem. However, another common problem is applying optimization. Hence, in this paper we propose an AAM based face recognition technique, which is capable of resolving the fitting problem of AAM by introducing a new adaptive ABC algorithm. The adaptation increases the efficiency of fitting as against the conventional ABC algorithm. We have used three datasets: CASIA dataset, property 2.5D face dataset, and UBIRIS v1 images dataset in our experiments. The results have revealed that the proposed face recognition technique has performed effectively, in terms of accuracy of face recognition.

Alcohol, tobacco, and illegal drug use are pervasive throughout the world. Substance use problems are among the major contributors to the global disease burden, which includes disability and mortality. The benefits of treatment far outweigh the economic costs. Despite the availability of treatment services, however, the vast majority of people with substance use disorders do not seek or use treatment. Barriers to and unmet need for evidence-based treatment are widespread even in the United States. Women, adolescents, and young adults are especially vulnerable to adverse effects from substance abuse, but they face additional barriers to getting evidence-based treatment or other social/medical services. Substance use behaviors and the diseases attributable to substance use problems are preventable and modifiable. Yet the ever-changing patterns of substance use and associated problems require combined research and policy-making efforts from all parts of the world to establish a viable knowledge base to inform for prevention, risk-reduction intervention, effective use of evidence-based treatment, and rehabilitation for long-term recovery. The new international, open-access, peer-reviewed Substance Abuse and Rehabilitation (SAR) journal strives to provide an effective platform for sharing ideas for solutions and disseminating research findings globally. Substance use behaviors and problems have no boundaries. The journal welcomes papers from all regions of the world that address any aspect of substance use, abuse/dependence, intervention, treatment, and policy. The "open-access" journal makes cutting edge knowledge freely available to practitioners and researchers worldwide, and this is particularly important for addressing the global disease burden attributable to substance abuse.
Face Allotransplantation and Burns: a Review
A, Arno; JP, Barret; RA, Harrison; MG, Jeschke
2012-01-01
Burns may represent one of the main indications for face allotransplantation. Severely disfigured faces featuring a devastating appearance and great functional impairments are not only seen as burn sequelae, but also occur as a result of other traumatic injuries, oncological surgical resections, benign tumors (e.g., neurofibromatosis), and major congenital malformations. To date, sixteen human face composite tissue allotransplantations have been performed with success. Despite the initial scepticism about its applicability, due mainly to ethical and technical reasons, the previous worldwide cases and their associated positive outcomes –including acceptable immunosuppressive regimens, excellent aesthetic and functional results, and good psychological acceptance by the recipient- , enable the conclusion that face composite tissue allotransplantation has become another therapeutic strategy in the reconstructive surgical armamentarium, which bears special consideration when dealing with severely disfigured burned patients. The aim of this review is to describe the basics of face composite tissue allotransplantation and give an overview of some of the cases performed until now, with special attention paid to debating the pros and cons of its applicability in burn patients.

The chronic kidney disease (CKD) is a worldwide critical problem, especially in developing countries. CKD patients usually begin their treatment in advanced stages, which requires dialysis and kidney transplantation, and consequently, affects mortality rates. This issue is faced by a mobile health (mHealth) application (app) that aims to assist the early diagnosis and self-monitoring of the disease progression. A user-centered design (UCD) approach involving health professionals (nurse and nephrologists) and target users guided the development process of the app between 2012 and 2016. In-depth interviews and prototyping were conducted along with healthcare professionals throughout the requirements elicitation process. Elicited requirements were translated into a native mHealth app targeting the Android platform. Afterward, the Cohen's Kappa coefficient statistics was applied to evaluate the agreement between the app and three nephrologists who analyzed test results collected from 60 medical records. Finally, eight users tested the app and were interviewed about usability and user perceptions. A mHealth app was designed to assist the CKD early diagnosis and self-monitoring considering quality attributes such as safety, effectiveness, and usability. A global Kappa value of 0.7119 showed a substantial degree of agreement between the app and three nephrologists. Results of face-to-face interviews with target users indicated a good user satisfaction. However, the task of CKD self-monitoring proved difficult because most of the users did not fully understand the meaning of specific biomarkers (e.g., creatinine). The UCD approach provided mechanisms to develop the app based on the real needs of users. Even with no perfect Kappa degree of agreement, results are satisfactory because it aims to refer patients to nephrologists in early stages, where they may confirm the CKD diagnosis.

Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, energy and goods are compromising fish populations through a variety of mechanisms, including overfishing, habitat degradation and declines in water quality. The important challenges raised by these issues have been recognized and have led to considerable advances over past decades in managing and mitigating threats to fishes worldwide. In this review, we identify the major threats faced by fish populations alongside recent advances that are helping to address these issues. There are very significant efforts worldwide directed towards ensuring a sustainable future for the world's fishes and fisheries and those who rely on them. Although considerable challenges remain, by drawing attention to successful mitigation of threats to fish and fisheries we hope to provide the encouragement and direction that will allow these challenges to be overcome in the future. © 2018 The Authors.

Post-Fukushima Energy and Nuclear Policy Evolution
NASA Astrophysics Data System (ADS)
Masuda, Tatsuo
2014-07-01
The Fukushima nuclear disaster should be marked as a point of departure towards energy policy evolution needed in the 21st century. Japan had cast off the skin after the oil shocks of the 1970s, where energy efficiency and saving played a critical role. Japan might have looked very different without these innovative policies. The post-Fukushima Japan faces multiple challenges, each of which constitutes a daunting task for policymakers such as surging LNG import costs and nuclear restarting. However, overcoming these problems one by one is not enough. Intensifying climate impact alerts us to the arrival of a historical inflection point requiring a radical shift in energy model worldwide, where Japan will be best suited to take the lead in view of its energy history and technology. The on-going effort after Fukushima to renew her energy and nuclear policy is suggestive of her potential to develop an innovative energy model by casting off the skin again. Asia will become the "problem centre" of the world if it may fail to address global environmental problems deriving from the heavy use of energy (about 46% of world's energy used by Asia alone in 2035). If successful, on the contrary, Asia will become the "solution centre" benefiting the global community. Asia is too big to fail as the whole world will be badly affected. The new energy model of Japan will serve as "public goods" for Asian countries in developing their new energy model towards sustainable future.

Catastrophic expenditure to pay for surgery worldwide: a modelling study.
Shrime, Mark G; Dare, Anna J; Alkire, Blake C; O'Neill, Kathleen; Meara, John G
2015-04-27
Approximately 150 million individuals worldwide face catastrophic expenditure each year from medical costs alone, and the non-medical costs of accessing care increase that number. The proportion of this expenditure related to surgery is unknown. Because the World Bank has proposed elimination of medical impoverishment by 2030, the effect of surgical conditions on financial catastrophe should be quantified so that any financial risk protection mechanisms can appropriately incorporate surgery. To estimate the global incidence of catastrophic expenditure due to surgery, we built a stochastic model. The income distribution of each country, the probability of requiring surgery, and the medical and non-medical costs faced for surgery were incorporated. Sensitivity analyses were run to test the robustness of the model. 3·7 billion people (posterior credible interval 3·2-4·2 billion) risk catastrophic expenditure if they need surgery. Each year, 81·3 million people (80·8-81·7 million) worldwide are driven to financial catastrophe-32·8 million (32·4-33·1 million) from the costs of surgery alone and 48·5 million (47·7-49·3) from associated non-medical costs. The burden of catastrophic expenditure is highest in countries of low and middle income; within any country, it falls on the poor. Estimates were sensitive to the definition of catastrophic expenditure and the costs of care. The inequitable burden distribution was robust to model assumptions. Half the global population is at risk of financial catastrophe from surgery. Each year, surgical conditions cause 81 million individuals to face catastrophic expenditure, of which less than half is attributable to medical costs. These findings highlight the need for financial risk protection for surgery in health-system design. MGS received partial funding from NIH/NCI R25CA92203. Copyright © 2015 Shrime et al.

Worldwide application of prevention science in adolescent health
Catalano, Richard F; Fagan, Abigail A; Gavin, Loretta E; Greenberg, Mark T; Irwin, Charles E; Ross, David A; Shek, Daniel T L
2015-01-01
The burden of morbidity and mortality from non-communicable disease has risen worldwide and is accelerating in low-income and middle-income countries, whereas the burden from infectious diseases has declined. Since this transition, the prevention of non-communicable disease as well as communicable disease causes of adolescent mortality has risen in importance. Problem behaviours that increase the short-term or long-term likelihood of morbidity and mortality, including alcohol, tobacco, and other drug misuse, mental health problems, unsafe sex, risky and unsafe driving, and violence are largely preventable. In the past 30 years new discoveries have led to prevention science being established as a discipline designed to mitigate these problem behaviours. Longitudinal studies have provided an understanding of risk and protective factors across the life course for many of these problem behaviours. Risks cluster across development to produce early accumulation of risk in childhood and more pervasive risk in adolescence. This understanding has led to the construction of developmentally appropriate prevention policies and programmes that have shown short-term and long-term reductions in these adolescent problem behaviours. We describe the principles of prevention science, provide examples of efficacious preventive interventions, describe challenges and potential solutions to take efficacious prevention policies and programmes to scale, and conclude with recommendations to reduce the burden of adolescent mortality and morbidity worldwide through preventive intervention.

Optimization and performance of bifacial solar modules: A global perspective

With the rapidly growing interest in bifacial photovoltaics (PV), a worldwide map of their potential performance can help assess and accelerate the global deployment of this emerging technology. However, the existing literature only highlights optimized bifacial PV for a few geographic locations or develops worldwide performance maps for very specific configurations, such as the vertical installation. It is still difficult to translate these location- and configuration-specific conclusions to a general optimized performance of this technology. In this paper, we present a global study and optimization of bifacial solar modules using a rigorous and comprehensive modeling framework. Our results demonstrate thatmore » with a low albedo of 0.25, the bifacial gain of ground-mounted bifacial modules is less than 10% worldwide. However, increasing the albedo to 0.5 and elevating modules 1 m above the ground can boost the bifacial gain to 30%. Moreover, we derive a set of empirical design rules, which optimize bifacial solar modules across the world and provide the groundwork for rapid assessment of the location-specific performance. We find that ground-mounted, vertical, east-west-facing bifacial modules will outperform their south-north-facing, optimally tilted counterparts by up to 15% below the latitude of 30 degrees, for an albedo of 0.5. The relative energy output is reversed in latitudes above 30 degrees.

The Family Adaptability and Cohesion Evaluation Scale (FACES) III using the circumplex model has been widely used in investigating family function. However, the criticism of the curvilinear hypothesis of the circumplex model has always been from an empirical point of view. This study examined the relationship between adolescent adaptability, cohesion, and adolescent problem behaviors, and especially testing the consistency of the curvilinear hypotheses with FACES III. We used the data from 398 adolescent participants who were in middle school. A self-reported questionnaire was used to evaluate the FACES III and Youth Self Report. According to the level of family adaptability, significant differences were evident in internalizing problems (P = 0.014). But, in externalizing problems, the results were not significant (P = 0.305). Also, according to the level of family cohesion, significant differences were in internalizing problems (P = 0.002) and externalizing problems (P = 0.004). The relationship between the dimensions of adaptability, cohesion and adolescent problem behaviors was not curvilinear. In other words, adolescents with high adaptability and high cohesion showed low problem behaviors.

However, very few studies described prevalence, similarities and differences among face-to-face victims, cybervictims and students who are victimised through both bullying and cyberbullying. This study was conducted to describe these different patterns of victimisation and severity of victimisation, emotional intelligence and technology use in different types of victims. A total number of 2,139 secondary school students from 22 schools, randomly selected from all provinces of Andalusia, Spain, participated in this study. Information about bullying, cyberbullying, social networking sites use and perceived emotional intelligence was collected. Face-to-face victimisation only is the most common type of victimisation followed by mixed victimisation. Cybervictimisation only is rare. Mixed victims score higher in severity of bullying and present higher emotional attention than face-to-face victims. Most victims of cyberbullying are also face-to-face victims. Holistic approach that focuses on different problems at the same time seems to be needed to tackle these behaviours.
3D face recognition based on multiple keypoint descriptors and sparse representation.

Recent years have witnessed a growing interest in developing methods for 3D face recognition. However, 3D scans often suffer from the problems of missing parts, large facial expressions, and occlusions. To be useful in real-world applications, a 3D face recognition approach should be able to handle these challenges. In this paper, we propose a novel general approach to deal with the 3D face recognition problem by making use of multiple keypoint descriptors (MKD) and the sparse representation-based classification (SRC). We call the proposed method 3DMKDSRC for short. Specifically, with 3DMKDSRC, each 3D face scan is represented as a set of descriptor vectors extracted from keypoints by meshSIFT. Descriptor vectors of gallery samples form the gallery dictionary. Given a probe 3D face scan, its descriptors are extracted at first and then its identity can be determined by using a multitask SRC. The proposed 3DMKDSRC approach does not require the pre-alignment between two face scans and is quite robust to the problems of missing data, occlusions and expressions. Its superiority over the other leading 3D face recognition schemes has been corroborated by extensive experiments conducted on three benchmark databases, Bosphorus, GavabDB, and FRGC2.0. The Matlab source code for 3DMKDSRC and the related evaluation results are publicly available at http://sse.tongji.edu.cn/linzhang/3dmkdsrcface/3dmkdsrc.htm.

2012-01-01
The present study was conducted to assess the problems faced by adolescents whose parents suffer from major mental illness at selected mental health institutes of Delhi. The objectives also included assessment of the coping strategies of the adolescents in dealing with these problems. The Stuart Stress Adaptation Model of Psychiatric Nursing Care was used as the conceptual framework. A descriptive survey approach with cross-sectional design was used in the study. A structured interview schedule was prepared. Purposive non-probability sampling technique was employed to interview 50 adolescents whose parents suffer from major mental illness. Data gathered was analysed and interpreted using both descriptive and inferential statistics. The study showed that majority of the adolescents had moderate problems as a result of their parent's mental illness. Area-wise analysis of the problems revealed that the highest problems faced were in family relationship and support and majority of the adolescents used maladaptive coping strategies. A set of guidelines on effective coping strategies was disseminated to these adolescents.

Recently, in Tarzia (Thermal Sci 21A:1-11, 2017) for the classical two-phase Lamé-Clapeyron-Stefan problem an equivalence between the temperature and convective boundary conditions at the fixed face under a certain restriction was obtained. Motivated by this article we study the two-phase Stefan problem for a semi-infinite material with a latent heat defined as a power function of the position and a convective boundary condition at the fixed face. An exact solution is constructed using Kummer functions in case that an inequality for the convective transfer coefficient is satisfied generalizing recent works for the corresponding one-phase free boundary problem. We also consider the limit to our problem when that coefficient goes to infinity obtaining a new free boundary problem, which has been recently studied in Zhou et al. (J Eng Math 2017. https://doi.org/10.1007/s10665-017-9921-y).

An investigation of the effects of interventions on problem-solving strategies and abilities
NASA Astrophysics Data System (ADS)
Cox, Charles Terrence, Jr.
Problem-solving has been described as being the "heart" of the chemistry classroom, and students' development of problem-solving skills is essential for their success in chemistry. Despite the importance of problem-solving, there has been little research within the chemistry domain, largely because of the lack of tools to collect data for large populations. Problem-solving was assessed using a software package known as IMMEX (for Interactive Multimedia Exercises) which has an HTML tracking feature that allows for collection of problem-solving data in the background as students work the problems. The primary goal of this research was to develop methods (known as interventions) that could promote improvements in students' problem-solving and most notably aid in their transition from the novice to competent level. Three intervention techniques that were incorporated within the chemistry curricula: collaborative grouping (face-to-face and distance), concept mapping, and peer-led team learning. The face-to-face collaborative grouping intervention was designed to probe the factors affecting the quality of the group interaction. Students' logical reasoning abilities were measured using the Group Assessment of Logical Thinking (GALT) test which classifies students as formal, transitional, or concrete. These classifications essentially provide a basis for identifying scientific aptitude. These designations were used as the basis for forming collaborative groups of two students. The six possibilities (formal-formal, formal-transitional, etc.) were formed to determine how the group composition influences the gains in student abilities observed from collaborative grouping interventions. Students were given three assignments (an individual pre-collaborative, an individual post collaborative, and a collaborative assignment) each requiring them to work an IMMEX problem set. Similar gains in performance of 10% gains were observed for each group with two exceptions. The transitional students who were paired with concrete students had a 15% gain, and the concrete students paired with other concrete students had only a marginal gain. In fact, there was no statistical difference in the pre-collaborative and post-collaborative student abilities for concrete-concrete groups. The distance collaborative intervention was completed using a new interface for the IMMEX software designed to mimic face-to-face collaboration. A stereochemistry problem set which had a solved rate of 28% prior to collaboration was chosen for incorporation into this distance collaboration study. (Abstract shortened by UMI.)

Guided Internet- and mobile-based interventions (IMIs) are an effective and scientifically sound treatment option for depression. Meta-analyses revealed effect sizes comparable to those found for face-to-face treatment as well as pharmacotherapy. Today, most IMIs are based on cognitive behavioral therapy (CBT). While IMIs are well established in healthcare systems of many countries worldwide, Germany is still lagging behind. However, there are an increasing number of model projects trying to implement IMIs into routine healthcare for depression in Germany. Both, service providers and recipients would benefit from transparent quality assurance and data safety guidelines. © Georg Thieme Verlag KG Stuttgart · New York.

Alcohol abuse and alcohol-related use problems among adolescents are highly prevalent and are a major concern worldwide. This study estimated the prevalence of drug abuse, knowledge about drug abuse and its effect on psychosocial well-being and induced behavioral problems among students of a public rural secondary school that admitted both girls and boys which offered both boarding and day school facilities. The students filled out a self-reporting substance use tool which measures the prevalence, frequency, and general patterns of substance use. Alcohol, tobacco, khat (catha edulis) and bhang (cannabis) were the most commonly reported substance of use, with user prevalence rates of 5.2%, 3.8%, 3.2%, and 1.7%, respectively. Tobacco use was initiated at 10 years, while cannabis, hard drugs, khat, and alcohol were initiated at 11, 12, 13, and 15 years of age, respectively. Among the students 71% were aware that their schoolmates were on drugs and it was known by 49.8%, 41.7%, 37.6%, 44.3%, and 32.4% of these students that using alcohol, tobacco, khat, cannabis, and hard drugs, respectively was a behavioral problem in the school. Three quarters of the students were aware that use of drugs was harmful to their health, with majority (78.6%) indicating that drug users need help to stop the drug use behavior. However most (73.6%) of the students suggested drug users in school should be punished. The drug use behavioral problems included school dropout, poor scholastic attainment, drunken driving, delinquency, and adolescence pregnancy which threaten the stability of the education system, family as an institution (family difficulties) and society at large. Therefore, teachers have an added burden of playing an active role in guidance and counselling the survivors of drug abuse, a pandemic facing teaching institutions apart from instilling knowledge.

Pesticide poisoning from agricultural labor has been recognized as a major public health problem among farmers worldwide. The objective of this study was to examine the incidence of acute occupational pesticide poisoning among male farmers in South Korea. A nationwide sampling survey of male farmers was conducted in South Korea. This survey used a stratified multistage probability sampling design and adopted the face-to-face interview method. A total of 1,958 male farmers were interviewed in order to estimate the incidence of acute occupational pesticide poisoning in rural areas in 2010. Based on a self-reported definition, the incidence rate in 2010 and the lifetime hospitalization rate due to acute occupational pesticide poisoning among male farmers were estimated. The incidence rate of acute occupational pesticide poisoning was 24.7 (95% CI 22.1-27.2) per 100 male farmers, which corresponds to 209,512 cases across South Korea in 2010. About 12% of the pesticide poisoning cases included either visiting a medical doctor or hospitalization. The lifetime rate of hospitalization due to occupational pesticide poisoning was 6.1 (95% CI 4.9-7.3) among male farmers. Poisoning occurred mainly when farmers were applying pesticides during summer. Our nationwide sampling survey demonstrated that acute occupational pesticide poisonings are highly prevalent among male South Korean farmers. Intensive intervention efforts to reduce occupational pesticide poisoning are urgently needed in South Korea. Copyright © 2012 Wiley Periodicals, Inc.

Worldwide, cattle production is struggling to face the negative impacts caused by ticks and Rhipicephalus (Boophilus) microplus is one of the most harmful ticks for livestock. Most of the people in West Africa depend on cattle farming and subsistence agriculture. The presence of ticks on cattle is a major problem faced by smallholder farmers who fight for their livelihood. National and regional tick control programs could assist these rural communities in protecting their livelihoods against ticks and tick-borne diseases, but only if they take into account the targeted herders and their perception on cattle management and tick control. This paper aims to provide a better insight in the socio-economic characteristics of Beninese cattle farmers, and their perception on tick burden, as well as to document common tick control strategies. Different tick species and their seasonality are well understood by cattle herders. For tick control, many still use manual tick removal, especially in the north of the country. The high cost of acaricides, the lack of financial means of African farmers, and of the local stockbreeders in particular, limits the use of acaricides in livestock breeding in Benin. While aiming to increase the meat or milk production of their animals, stockbreeders who can afford it sometimes turn to an abusive use of acaricides, which might in time lead to an increase in tick resistance. This study remains one of the rare studies to report extensively on the perceptions of West African cattle herders.
Universal Skills and Competencies for Geoscientists
NASA Astrophysics Data System (ADS)
Mosher, S.
2015-12-01
Geoscience students worldwide face a changing future workforce, but all geoscience work has universal cross-cutting skills and competencies that are critical for success. A recent Geoscience Employers Workshop, and employers' input on the "Future of Undergraduate Geoscience Education" survey, identified three major areas. Geoscience work requires spatial and temporal (3D & 4D) thinking, understanding that the Earth is a system of interacting parts and processes, and geoscience reasoning and synthesis. Thus, students need to be able to solve problems in the context of an open and dynamic system, recognizing that most geoscience problems have no clear, unambiguous answers. Students must learn to manage uncertainty, work by analogy and inference, and make predations with limited data. Being able to visualize and solve problems in 3D, incorporate the element of time, and understand scale is critical. Additionally students must learn how to tackle problems using real data, including understand the problems' context, identify appropriate questions to ask, and determine how to proceed. Geoscience work requires integration of quantitative, technical, and computational skills and the ability to be intellectually flexible in applying skills to new situations. Students need experience using high-level math and computational methods to solve geoscience problems, including probability and statistics to understand risk. Increasingly important is the ability to use "Big Data", GIS, visualization and modeling tools. Employers also agree a strong field component in geoscience education is important. Success as a geoscientist also requires non-technical skills. Because most work environments involve working on projects with a diverse team, students need experience with project management in team settings, including goal setting, conflict resolution, time management and being both leader and follower. Written and verbal scientific communication, as well as public speaking and listening skills, are important. Success also depends on interpersonal skills and professionalism, including business acumen, risk management, ethical conduct, and leadership. A global perspective is increasingly important, including cultural literacy and understanding societal relevance.

A survey of the dummy face and human face stimuli used in BCI paradigm.
Chen, Long; Jin, Jing; Zhang, Yu; Wang, Xingyu; Cichocki, Andrzej
2015-01-15
It was proved that the human face stimulus were superior to the flash only stimulus in BCI system. However, human face stimulus may lead to copyright infringement problems and was hard to be edited according to the requirement of the BCI study. Recently, it was reported that facial expression changes could be done by changing a curve in a dummy face which could obtain good performance when it was applied to visual-based P300 BCI systems. In this paper, four different paradigms were presented, which were called dummy face pattern, human face pattern, inverted dummy face pattern and inverted human face pattern, to evaluate the performance of the dummy faces stimuli compared with the human faces stimuli. The key point that determined the value of dummy faces in BCI systems were whether dummy faces stimuli could obtain as good performance as human faces stimuli. Online and offline results of four different paradigms would have been obtained and comparatively analyzed. Online and offline results showed that there was no significant difference among dummy faces and human faces in ERPs, classification accuracy and information transfer rate when they were applied in BCI systems. Dummy faces stimuli could evoke large ERPs and obtain as high classification accuracy and information transfer rate as the human faces stimuli. Since dummy faces were easy to be edited and had no copyright infringement problems, it would be a good choice for optimizing the stimuli of BCI systems. Copyright © 2014 Elsevier B.V.

The role and demands of studying nursing and medicine involve specific stressors that may contribute to an increased risk for mental health problems. Stigma is a barrier to help-seeking for mental health problems in nursing and medical students, making these students vulnerable to negative outcomes including higher failure rates and discontinuation of study. Mental Health First Aid (MHFA) is a potential intervention to increase the likelihood that medical and nursing students will support their peers to seek help for mental health problems. This study aimed to evaluate the effectiveness of a tailored MHFA course for nursing and medical students. Nursing and medical students self-selected into either a face-to-face or online tailored MHFA course. Four hundred and thirty-four nursing and medical students completed pre- and post-course surveys measuring mental health first aid intentions, mental health literacy, confidence in providing help, stigmatising attitudes and satisfaction with the course. The results of the study showed that both the online and face-to-face courses improved the quality of first aid intentions towards a person experiencing depression, and increased mental health literacy and confidence in providing help. The training also decreased stigmatizing attitudes and desire for social distance from a person with depression. Both online and face-to-face tailored MHFA courses have the potential to improve outcomes for students with mental health problems, and may benefit the students in their future professional careers.

End-stage renal disease is a worldwide problem that requires highly skilled nursing care. Hemodialysis (HD) is a corner-stone procedure in the management of most patients who require renal replacement therapy. Adequate vascular access is essential for the successful use of HD. Appropriate knowledge in taking care of vascular access is essential for minimizing complications and accurately recognizing vascular access-related problems. This study was to evaluate the effect of an educational program for vascular access care on nurses' knowledge at nine dialysis centers in Khartoum State. This was a Quasi experimental study (pre-and post-test for the same group). Sixty-one nurses working in these HD centers were chosen by simple random sampling method. A structured face-to-face interview questionnaire based on the Kidney Dialysis Outcome Quality Initiative (K/DOQI) clinical practice guidelines for vascular access care was used. Instrument validity was determined through content validity by a panel of experts. Reliability of the instrument was tested by a pilot study to test the knowledge scores for 15 nurses. The Pearson correlation coefficient obtained was (r = 0.82). Data collection was taken before and after the educational intervention. A follow-up test was performed three month later, using the same data collection tools. Twenty-two individual variables assessing the knowledge levels in aspects related to the six K/DOQI guidelines showed improvement in all scores of the nurses' knowledge after the educational intervention; and the differences from the preeducational scores were statistically significant (P < 0.001). The study showed that a structured educational program based on the K/DOQI clinical practice guidelines had a significant impact on the dialysis nurses knowledge in caring for vascular access in HD patients. The knowledge level attained was maintained for at least three months after the educational intervention.
Robust Face Recognition via Multi-Scale Patch-Based Matrix Regression.
Gao, Guangwei; Yang, Jian; Jing, Xiaoyuan; Huang, Pu; Hua, Juliang; Yue, Dong
2016-01-01
In many real-world applications such as smart card solutions, law enforcement, surveillance and access control, the limited training sample size is the most fundamental problem. By making use of the low-rank structural information of the reconstructed error image, the so-called nuclear norm-based matrix regression has been demonstrated to be effective for robust face recognition with continuous occlusions. However, the recognition performance of nuclear norm-based matrix regression degrades greatly in the face of the small sample size problem. An alternative solution to tackle this problem is performing matrix regression on each patch and then integrating the outputs from all patches. However, it is difficult to set an optimal patch size across different databases. To fully utilize the complementary information from different patch scales for the final decision, we propose a multi-scale patch-based matrix regression scheme based on which the ensemble of multi-scale outputs can be achieved optimally. Extensive experiments on benchmark face databases validate the effectiveness and robustness of our method, which outperforms several state-of-the-art patch-based face recognition algorithms.
3D Face Recognition Based on Multiple Keypoint Descriptors and Sparse Representation
Zhang, Lin; Ding, Zhixuan; Li, Hongyu; Shen, Ying; Lu, Jianwei
2014-01-01
Recent years have witnessed a growing interest in developing methods for 3D face recognition. However, 3D scans often suffer from the problems of missing parts, large facial expressions, and occlusions. To be useful in real-world applications, a 3D face recognition approach should be able to handle these challenges. In this paper, we propose a novel general approach to deal with the 3D face recognition problem by making use of multiple keypoint descriptors (MKD) and the sparse representation-based classification (SRC). We call the proposed method 3DMKDSRC for short. Specifically, with 3DMKDSRC, each 3D face scan is represented as a set of descriptor vectors extracted from keypoints by meshSIFT. Descriptor vectors of gallery samples form the gallery dictionary. Given a probe 3D face scan, its descriptors are extracted at first and then its identity can be determined by using a multitask SRC. The proposed 3DMKDSRC approach does not require the pre-alignment between two face scans and is quite robust to the problems of missing data, occlusions and expressions. Its superiority over the other leading 3D face recognition schemes has been corroborated by extensive experiments conducted on three benchmark databases, Bosphorus, GavabDB, and FRGC2.0. The Matlab source code for 3DMKDSRC and the related evaluation results are publicly available at http://sse.tongji.edu.cn/linzhang/3dmkdsrcface/3dmkdsrc.htm. PMID:24940876

Plastic surgery procedures on the face introduce skin texture variations between images of the same person (intra-subject), thereby making the task of face recognition more difficult than in normal scenario. Usually, in contemporary face recognition systems, the original gray-level face image is used as input to the Gabor descriptor, which translates to encoding some texture properties of the face image. The texture-encoding process significantly degrades the performance of such systems in the case of plastic surgery due to the presence of surgically induced intra-subject variations. Based on the proposition that the shape of significant facial components such as eyes, nose, eyebrow, and mouth remains unchanged after plastic surgery, this paper employs an edge-based Gabor feature representation approach for the recognition of surgically altered face images. We use the edge information, which is dependent on the shapes of the significant facial components, to address the plastic surgery-induced texture variation problems. To ensure that the significant facial components represent useful edge information with little or no false edges, a simple illumination normalization technique is proposed for preprocessing. Gabor wavelet is applied to the edge image to accentuate on the uniqueness of the significant facial components for discriminating among different subjects. The performance of the proposed method is evaluated on the Georgia Tech (GT) and the Labeled Faces in the Wild (LFW) databases with illumination and expression problems, and the plastic surgery database with texture changes. Results show that the proposed edge-based Gabor feature representation approach is robust against plastic surgery-induced face variations amidst expression and illumination problems and outperforms the existing plastic surgery face recognition methods reported in the literature.
Reflections on the maternal mortality millennium goal.
Lawson, Gerald W; Keirse, Marc J N C
2013-06-01
Nearly every 2 minutes, somewhere in the world, a woman dies because of complications of pregnancy and childbirth. Every such death is an overwhelming catastrophe for everyone confronted with it. Most deaths occur in developing countries, especially in Africa and southern Asia, but a significant number also occur in the developed world. We examined the available data on the progress and the challenges to the United Nations' fifth Millennium Development Goal of achieving a 75 percent worldwide reduction in the maternal mortality by 2015 from what it was in 1990. Some countries, such as Belarus, Egypt, Estonia, Honduras, Iran, Lithuania, Malaysia, Romania, Sri Lanka and Thailand, are likely to meet the target by 2015. Many poor countries with weak health infrastructures and high fertility rates are unlikely to meet the goal. Some, such as Botswana, Cameroon, Chad, Congo, Guyana, Lesotho, Namibia, Somalia, South Africa, Swaziland and Zimbabwe, had worse maternal mortality ratios in 2010 than in 1990, partially because of wars and civil strife. Worldwide, the leading causes of maternal death are still hemorrhage, hypertension, sepsis, obstructed labor, and unsafe abortions, while indirect causes are gaining in importance in developed countries. Maternal death is especially distressing if it was potentially preventable. However, as there is no single cause, there is no silver bullet to correct the problem. Many countries also face new challenges as their childbearing population is growing in age and in weight. Much remains to be done to make safe motherhood a reality. © 2013, Copyright the Authors, Journal compilation © 2013, Wiley Periodicals, Inc.

Since Oxford dictionary has described 'Selfie', selfie deaths have received a fair amount of coverage but the extent of the problem and the data behind it have not been appropriately explored. The aim of our study is to obtain epidemiological characteristics of selfie-related mortality worldwide with the objective of providing an insight to 'Why selfie', 'Why risky', 'Psychological basis' and 'measures of control.' Despite thousands of web pages, very few scientific articles are available in medical journals. So, we went online via Google search engine compiling every reported instance after confirming it and verifying the information in Wikipedia. Non-fatal injuries and non-selfie type of photography-related deaths were excluded from the study. From 2014 to mid-2016, 75 people have died while attempting selfie in 52 incidents worldwide. Mean age of the victims was 23.3 and 82% were male. India is the most affected country and Russia and US being second. Fall from height, drowning and rail accidents are the top three modes of death. Large-scale use of cell phone worldwide and underlying risk in selfie behaviour seems the culprit. Inability to compare selfie with non-selfie photography due to lack of data is definitely a limitation. Worldwide initiatives are being taken like 'NO SELFIE ZONES' but still a multifactorial approach is required before it gets too late.

Naïve Human Antibody Libraries for Infectious Diseases.
Chan, Soo Khim; Rahumatullah, Anizah; Lai, Jing Yi; Lim, Theam Soon
2017-01-01
Many countries are facing an uphill battle in combating the spread of infectious diseases. The constant evolution of microorganisms magnifies the problem as it facilitates the re-emergence of old infectious diseases as well as promote the introduction of new and more deadly variants. Evidently, infectious diseases have contributed to an alarming rate of mortality worldwide making it a growing concern. Historically, antibodies have been used successfully to prevent and treat infectious diseases since the nineteenth century using antisera collected from immunized animals. The inherent ability of antibodies to trigger effector mechanisms aids the immune system to fight off pathogens that invades the host. Immune libraries have always been an important source of antibodies for infectious diseases due to the skewed repertoire generated post infection. Even so, the role and ability of naïve antibody libraries should not be underestimated. The naïve repertoire has its own unique advantages in generating antibodies against target antigens. This chapter will highlight the concept, advantages and application of human naïve libraries as a source to isolate antibodies against infectious disease target antigens.

The bioaccumulation of polycyclic aromatic compounds originating from textile processing industries is nowadays a major environmental problem worldwide. In order to tackle this situation, several inorganic semiconductors have been tested as photocatalysts for the degradation of these harmful pollutants in the search of sustainable and cost-effective solutions. Nevertheless, these semiconductor materials often involve important limitations, such as poor efficiency and selectivity, which, in the end, substantially restrict their implementation at the industrial scale. As an alternative, we herein report the fabrication and application of Au-decorated titanate nanotubes (TNTs) as high-performance architectures for the selective degradation of organic contaminants. This synthetic strategy is intended to establish a synergetic integration of the physicochemical and photocatalytic features of these hybrid nanostructures, by combining the remarkable adsorption capabilities of TNTs with the enhanced light-harvesting efficiency provided by the incorporation of a noble metal component. The obtained results evidence the great potential that rationally designed plasmonic composites may have for the development of selective environmental remediation technologies and in particular on the current challenges faced by the wastewater treatment sector.

The abnormal or excessive fat accumulation that impairs health is one of the criteria that fulfills obesity. According to epidemiological data, obesity has become a worldwide public health problem that in turn would trigger additional pathologies such as cardiorespiratory dysfunctions, cancer, gastrointestinal disturbances, depression, sleep disorders, just to mention a few. Then, the search for a therapeutical intervention aimed to prevent and manage obesity has been the focus of study during the last years. As one can assume, the increased prevalence of obesity has translated to search of efficient pharmaceuticals designed to manage this health issue. However, to further complicate the scenario, scientific literature has described that obesity is the result of interaction between multiple events. Therefore, pharmacological approaches have faced a serious challenge for develop the adequate treatment. Here, we argue that a wide range of non-pharmacological/invasive techniques can be used to manage obesity, such as diets, cognitive behavioral interventions, exercise and transcranial direct current stimulation. Combining these techniques may allow improving quality of life of obese patients. Copyright © 2018 European Society for Clinical Nutrition and Metabolism. Published by Elsevier Ltd.

The epidemic of HIV/AIDS in developing countries; the current scenario in Pakistan.
Yousaf, Muhammad Z; Zia, Sadia; Babar, Masroor E; Ashfaq, Usman A
2011-08-12
HIV (Human Immunodeficiency virus) causes (acquired immunodeficiency syndrome) AIDS, in which the immune system of body totally fails to develop any defense against the foreign invaders. Infection with HIV occurs by transfer of blood, semen, and breast milk. HIV/AIDS is a global problem and it results nearly 25 million deaths worldwide. Developing countries like Pakistan have issues regarding Public Health. Currently, epidemic of HIV/AIDS is established in Pakistan and there is a threat of an expanded HIV/AIDS outbreak in the country. The major reason is that population is engaging in high-risk practices, low awareness about HIV/AIDS, and treacherous blood transfusion practices. A supplementary threat to Pakistan is India because both sharing a border and India is facing a rapidly growing HIV/AIDS epidemic. Local NGOs, National and International organizations are warning that in near future Pakistan may experiences bad situation regarding HIV/AIDS.In the present article we focused current situation of surveillance of HIV/AIDS, its virology, genotype, diagnostics, high-risk groups, reasons of vulnerability in Pakistani population, and the role of different national and international organizations in this situation.
Racial and Gender Issues with Physics in the Pacific Region

This paper examines the state of physics teaching and learning in the Pacific Island nations. How have things changed in teaching physics? We believe that some of the goals and many of the challenges faced today have changed very little over the years. This paper is purely based upon the authors' experiences in teaching physics at the first-year level at the University of the South Pacific (USP). USP is a typical medium-sized teaching and research university as compared to universities internationally. In the Pacific, it is the biggest university and is effectively serving the 12 Pacific Island nations. Consequently, the findings described here should represent the overall situation for the Pacific region. Perhaps some of our results will resonate with readers in other locations as well. Worldwide, university students often find studying physics to be very challenging, and only a small fraction of them choose physics as a major for their degree or as a career. Students at USP are not an exception, and here we describe the severity of the problem.
Managing flowback and produced water from hydraulic fracturing under stochastic environment

Zhang, X.; Sun, A. Y.; Duncan, I. J.; Vesselinov, V. V.
2017-12-01
A large volume of wastewater is being generated from hydraulic fracturing in shale gas plays, including flowback and produced water. The produced wastewater in terms of its quantity and quality has become one of the main environmental problems facing shale gas industries worldwide. Cost-effective planning and management of flowback and produced water is highly desirable. Careful choice of treatment, disposal, and reuse options can lower costs and reduce potential environmental impacts. To handle the recourse issue in decision-making, a two-stage stochastic management model is developed to provide optimal alternatives for fracturing wastewater management. The proposed model is capable of prompting corrective actions to allow decision makers to adjust the pre-defined management strategies. By using this two-stage model, potential penalties arising from decision infeasibility can be minimized. The applicability of the proposed model is demonstrated using a representative synthetic example, in which tradeoffs between economic and environmental goals are quantified. This approach can generate informed defensible decisions for shale gas wastewater management. In addition, probabilistic and non-probabilistic uncertainties are effectively addressed.
How To Create A Spacefaring Civilization (And Why Spacelaw Must Go Ahead!)

The human settlement of Mars is not so far away, and it is necessary to transform our current situation into a spacefaring civilization. But, how can we do it? First of all, we have to batter down the political, financial and engineer obstacles that have thus far obstructed humanity from entering the real space age. Then, we have to discuss the possibilities inherent in human activity for peering out into the universe and to explore the resources that will guarantee humankind's future existence. Finally, we have to solve technological and scientific problems associated with interstellar travels and the detection of other intelligent species in space. That's why spacelaw must go ahead. Space is the new face of industry and commerce, because it is plenty of resources for doing business. Matters such as space property and insurance; urban planning; space-business opportunities (space tourism, establishment of worldwide communication satellite networks, export of satellites for launch, exploitation of natural resources...); military uses of outer space; or national licensing for satellite services must be solve by spacelaw before they crop up.

Elevated CO(2) levels and the increase in heavy metals in soils through pollution are serious problems worldwide. Whether elevated CO(2) levels will affect plants grown in heavy-metal-polluted soil and thereby influence food quality and safety is not clear. Using a free-air CO(2) enrichment (FACE) system, we investigated the impacts of elevated atmospheric CO(2) on the concentrations of copper (Cu) or cadmium (Cd) in rice and wheat grown in soil with different concentrations of the metals in the soil. In the two-year study, elevated CO(2) levels led to lower Cu concentrations and higher Cd concentrations in shoots and grain of both rice and wheat grown in the respective contaminated soil. Elevated CO(2) levels slightly but significantly lowered the pH of the soil and led to changes in Cu and Cd fractionation in the soil. Our study indicates that elevated CO(2) alters the distribution of contaminant elements in soil and plants, thereby probably affecting food quality and safety.

Radioactive materials in recycled metals.
Lubenau, J O; Yusko, J G
1995-04-01
In recent years, the metal recycling industry has become increasingly aware of an unwanted component in metal scrap--radioactive material. Worldwide, there have been 35 instances where radioactive sources were unintentionally smelted in the course of recycling metal scrap. In some cases contaminated metal consumer products were distributed internationally. In at least one case, serious radiation exposures of workers and the public occurred. Radioactive material appearing in metal scrap includes sources subject to licensing under the Atomic Energy Act and also naturally occurring radioactive material. U.S. mills that have smelted a radioactive source face costs resulting from decontamination, waste disposal, and lost profits that range from 7 to 23 million U.S. dollars for each event. To solve the problem, industry and the government have jointly undertaken initiatives to increase awareness of the problem within the metal recycling industry. Radiation monitoring of recycled metal scrap is being performed increasingly by mills and, to a lesser extent, by scrap processors. The monitoring does not, however, provide 100% protection. Improvements in regulatory oversight by the government could stimulate improved accounting and control of licensed sources. However, additional government effort in this area must be reconciled with competing priorities in radiation safety and budgetary constraints. The threat of radioactive material in recycled metal scrap will continue for the foreseeable future and, thus, poses regulatory policy challenges for both developed and developing nations.
Are Australasian academic physicians an endangered species?
Wilson, A
2007-11-01
It has been stated that academic medicine is in a worldwide crisis. Is this decline in hospital academic practice a predictable consequence of modern clinical practice with its emphasis on community and outpatient-based services as well as a corporate health-care ethos or does it relate to innate problems in the training process and career structure for academic clinicians? A better understanding of the barriers to involvement in academic practice, including the effect of gender, the role and effect of overseas training, expectation of further research degrees and issues pertaining to the Australian academic workplace will facilitate recruitment and retention of the next generation of academic clinicians. Physician-scientists remain highly relevant as medical practice and education evolves in the 21st century. Hospital-based academics carry out a critical role in the ongoing mentoring of trainees and junior colleagues, whose training is still largely hospital based in most specialty programmes. Academic clinicians are uniquely placed to translate the rapid advances in medical biology into the clinical sphere, by guiding and carrying out translational research as well as leading clinical studies. Academic physicians also play key leadership in relations with government and industry, in professional groups and medical colleges. Thus, there is a strong case to assess the problems facing recruitment and retention of physician-scientists in academic practice and to develop workable solutions.

Preliminary outcomes from the previous nine face transplants performed since 2005 have been encouraging and have therefore led to a rise in the number of medical centers interested in establishing face transplant programs worldwide. However, until now, very little literature has been published providing surgeons the necessary insight on how to (1) prepare a protocol for institutional review board approval and (2) establish a face transplant program. The authors' face transplant team's experience with the institutional review board at the Cleveland Clinic, beginning in 2002, was critically reviewed in a detailed, retrospective manner. The purpose was to identify and define certain criteria necessary for both the institutional review board approval process and face transplant program establishment. In 2002, unprecedented efforts from within the authors' plastic surgery department led to the world's first institutional review board approval for face transplantation, in 2004. As a result, 4 years later, the authors' face transplant team performed the nation's first successful near-total face and maxilla transplant. Every surgical department hoping to establish a face transplant program must realize that this endeavor requires both tremendous financial and long-term commitments by its medical institution. These transplants should be performed only within university-based medical centers capable of orchestrating a specialized, talented, multidisciplinary team. More importantly, facial composite tissue allotransplantation possesses an unmatched level of complexity and therefore requires most centers to prepare a carefully detailed protocol using these institutional review board-based guidelines.

Although the number of female foreign domestic workers (FDWs) is increasing worldwide, little is known about their health issues. To systematically review the literature on health issues of female FDWs to ascertain the problems studied, identify limitations, and suggest future research and policy implications. A systematic database (PubMed, EBSCO Host, and Google Scholar) and bibliographic search identified the English-language scientific and gray literature published during 1990-2012 addressing health issues of female FDWs living with the family of the employer, using qualitative and/or quantitative research methods. Studies in which female FDWs constituted less than half of the participants were excluded. The health issues studied and identified were adverse work conditions and associated health problems (such as physical, verbal, and sexual abuse at the workplace, caregiving tasks associated with musculoskeletal strain, and chemical exposure associated with respiratory difficulty), mental health (psychotic, neurotic, and mood disorders), infectious diseases (most of the studies were on intestinal parasitic infections), and health knowledge/attitudes/practices (most of the studies were in context of sexual and reproductive health). Most of the studies were medical record reviews or questionnaire-based surveys utilizing convenience sampling or qualitative interviews/focus group discussions. Female FDWs face numerous health problems. Studies on representative, possibly longitudinal, samples of female FDWs focusing on specific health conditions are needed to better understand the epidemiology of such conditions. Concerted efforts through the governments of both labor-sending and host countries are required to improve the health, work conditions, and safety of this vulnerable group of women.

The author examines population issues facing countries in Oceania and Southeastern Asia. "Analysis is based on recently released population projections from the United Nations Population Division. There are great differences among the countries.... There are nonetheless important areas of commonality: all nations are facing the problem of raising levels of schooling in line with parents' aspirations and economic needs, all face problems of caring for a rising proportion of aged, and all have difficulties with the monitoring and control of international migration. Also, since minority groups in many countries are majority polities in neighbouring states, there is potential for establishing international dialogues aimed at relieving internal tensions." Consideration is given to the role of Australia in promoting international cooperation to deal with these issues. excerpt
What goes around, comes around: John Gregory, MD, and the profession of medicine
McCullough, Laurence B.
2007-01-01
Each generation of physicians believes the problems they face are unique. History shows that very few situations are new to medicine. Some appear to have been around for centuries (medical institutions' “cherry-picking” of patients, third-party interference in medical care), while others have been around for millennia (competition among physicians, competition between physicians and nonphysicians). This article describes problems of medicine faced by 18th-century medicine and the solutions to those problems proposed by Dr. John Gregory in the latter part of that century. Both the problems and his solutions seem surprisingly modern. PMID:17256037

3D Face Modeling Using the Multi-Deformable Method
Hwang, Jinkyu; Yu, Sunjin; Kim, Joongrock; Lee, Sangyoun
2012-01-01
In this paper, we focus on the problem of the accuracy performance of 3D face modeling techniques using corresponding features in multiple views, which is quite sensitive to feature extraction errors. To solve the problem, we adopt a statistical model-based 3D face modeling approach in a mirror system consisting of two mirrors and a camera. The overall procedure of our 3D facial modeling method has two primary steps: 3D facial shape estimation using a multiple 3D face deformable model and texture mapping using seamless cloning that is a type of gradient-domain blending. To evaluate our method's performance, we generate 3D faces of 30 individuals and then carry out two tests: accuracy test and robustness test. Our method shows not only highly accurate 3D face shape results when compared with the ground truth, but also robustness to feature extraction errors. Moreover, 3D face rendering results intuitively show that our method is more robust to feature extraction errors than other 3D face modeling methods. An additional contribution of our method is that a wide range of face textures can be acquired by the mirror system. By using this texture map, we generate realistic 3D face for individuals at the end of the paper. PMID:23201976

Face recognition is a widely used biometric technology due to its convenience but it is vulnerable to spoofing attacks made by nonreal faces such as photographs or videos of valid users. The antispoof problem must be well resolved before widely applying face recognition in our daily life. Face liveness detection is a core technology to make sure that the input face is a live person. However, this is still very challenging using conventional liveness detection approaches of texture analysis and motion detection. The aim of this paper is to propose a feature descriptor and an efficient framework that can be used to effectively deal with the face liveness detection problem. In this framework, new feature descriptors are defined using a multiscale directional transform (shearlet transform). Then, stacked autoencoders and a softmax classifier are concatenated to detect face liveness. We evaluated this approach using the CASIA Face antispoofing database and replay-attack database. The experimental results show that our approach performs better than the state-of-the-art techniques following the provided protocols of these databases, and it is possible to significantly enhance the security of the face recognition biometric system. In addition, the experimental results also demonstrate that this framework can be easily extended to classify different spoofing attacks.

Problem-solving strategies learned by physics undergraduates should prepare them for real-world contexts as they transition from students to professionals. Yet, graduate students in physics-intensive research face problems that go beyond problem sets they experienced as undergraduates and are solved by different strategies than are typically learned in undergraduate coursework. This paper expands the notion of problem solving by characterizing the breadth of problems and problem-solving processes carried out by graduate students in physics-intensive research. We conducted semi-structured interviews with ten graduate students to determine the routine, difficult, and important problems they engage in and problem-solving strategies they found useful in their research. A qualitative typological analysis resulted in the creation of a three-dimensional framework: context, activity, and feature (that made the problem challenging). Problem contexts extended beyond theory and mathematics to include interactions with lab equipment, data, software, and people. Important and difficult contexts blended social and technical skills. Routine problem activities were typically well defined (e.g., troubleshooting), while difficult and important ones were more open ended and had multiple solution paths (e.g., evaluating options). In addition to broadening our understanding of problems faced by graduate students, our findings explore problem-solving strategies (e.g., breaking down problems, evaluating options, using test cases or approximations) and characteristics of successful problem solvers (e.g., initiative, persistence, and motivation). Our research provides evidence of the influence that problems students are exposed to have on the strategies they use and learn. Using this evidence, we have developed a preliminary framework for exploring problems from the solver's perspective. This framework will be examined and refined in future work. Understanding problems graduate students face and the strategies they use has implications for improving how we approach problem solving in undergraduate physics and physics education research.

The total number of anatomy teaching hours has declined in medical courses worldwide. Conversely, face-to-face teaching in undergraduate neuroanatomy at Macquarie University increased by 50% in 2011. Our aim was to investigate whether this influenced student performance and overall satisfaction with the course. One hundred eighty-one students consented to participate in this study. A questionnaire was administered to rate the course, and final grades from the old and new unit cohorts were compared. The old and new unit cohorts did not differ in their final grades (P = 0.249). However, the new unit cohort rated their knowledge of the material higher compared to the old unit cohort (P = 0.013), and reported higher levels of satisfaction with the course (P < 0.001). In an era in which teaching time for anatomy has been reduced at tertiary institutions, and there is much lamenting of the effect this will have, there is a paucity of literature on whether the decrease really influences neuroanatomical knowledge. This is the first study, to the best of our knowledge, to show that an increase in total face-to-face teaching hours does not improve student grades, but does increase student satisfaction with the course. © 2012 American Association of Anatomists.

Restoration of the face function and cosmetic appearance after a traumatic complex wound is a challenge for the plastic surgeon. Worldwide, few cases have been reported about face replantation. To present the case of the first partial face replantation reported in the national bibliography, using the labial artery for revascularization. On June 19th 2011, a 7 years old male presented to the emergency room of the Mexican Institute of Social Security at Monterrey, Mexico, 4 hours after a partial face amputation secondary to a dog bite. The amputated segment was composed of 75% of the upper lip, 33% of the lower lip, oral commissure and 75% of the left cheek. The labial coronary artery and vein were anastomosed with 11-0 nylon sutures and the miorraphy of the orbicularis oris, the depressor anguli oris and the depressor labii inferioris with 4-0 vycril sutures. Six months after the surgery, the functional and aesthetic outcomes were excellent with reestablishment of total labial continence and total recovery of articulation of words. amputations of any facial component should be initially managed with replantation. The function and cosmetics are better than any other technique of reconstruction. The labial coronary artery is an excellent choice for revascularization up to 25% of the face (lips and cheek).

Objectives: Update on clinical results obtained by the first worldwide facial transplantation teams as well as review of the literature concerning the main surgical, immunological, ethical, and follow-up aspects described on facial transplanted patients. Study design: MEDLINE search of articles published on “face transplantation” until March 2012. Results: Eighteen clinical cases were studied. The mean patient age was 37.5 years, with a higher prevalence of men. Main surgical indication was gunshot injuries (6 patients). All patients had previously undergone multiple conventional surgical reconstructive procedures which had failed. Altogether 8 transplant teams belonging to 4 countries participated. Thirteen partial face transplantations and 5 full face transplantations have been performed. Allografts are varied according to face anatomical components and the amount of skin, muscle, bone, and other tissues included, though all were grafted successfully and remained viable without significant postoperative surgical complications. The patient with the longest follow-up was 5 years. Two patients died 2 and 27 months after transplantation. Conclusions: Clinical experience has demonstrated the feasibility of facial transplantation as a valuable reconstructive option, but it still remains considered as an experimental procedure with unresolved issues to settle down. Results show that from a clinical, technical, and immunological standpoint, facial transplantation has achieved functional, aesthetic, and social rehabilitation in severely facial disfigured patients. Key words:Face transplantation, composite tissue transplantation, face allograft, facial reconstruction, outcomes and complications of face transplantation. PMID:23229268

Liquid Metals as Plasma-facing Materials for Fusion Energy Systems: From Atoms to Tokamaks
DOE Office of Scientific and Technical Information (OSTI.GOV)
Stone, Howard A.; Koel, Bruce E.; Bernasek, Steven L.
The objective of our studies was to advance our fundamental understanding of liquid metals as plasma-facing materials for fusion energy systems, with a broad scope: from atoms to tokamaks. The flow of liquid metals offers solutions to significant problems of the plasma-facing materials for fusion energy systems. Candidate metals include lithium, tin, gallium, and their eutectic combinations. However, such liquid metal solutions can only be designed efficiently if a range of scientific and engineering issues are resolved that require advances in fundamental fluid dynamics, materials science and surface science. In our research we investigated a range of significant and timelymore » problems relevant to current and proposed engineering designs for fusion reactors, including high-heat flux configurations that are being considered by leading fusion energy groups world-wide. Using experimental and theoretical tools spanning atomistic to continuum descriptions of liquid metals, and bridging surface chemistry, wetting/dewetting and flow, our research has advanced the science and engineering of fusion energy materials and systems. Specifically, we developed a combined experimental and theoretical program to investigate flows of liquid metals in fusion-relevant geometries, including equilibrium and stability of thin-film flows, e.g. wetting and dewetting, effects of electromagnetic and thermocapillary fields on liquid metal thin-film flows, and how chemical interactions and the properties of the surface are influenced by impurities and in turn affect the surface wetting characteristics, the surface tension, and its gradients. Because high-heat flux configurations produce evaporation and sputtering, which forces rearrangement of the liquid, and any dewetting exposes the substrate to damage from the plasma, our studies addressed such evaporatively driven liquid flows and measured and simulated properties of the different bulk phases and material interfaces. The range of our studies included (i) quantum mechanical calculations that allow inclusion of many thousands of atoms for the characterization of the interface of liquid metals exposed to continuous bombardment by deuterium and tritium as expected in fusion, (ii) molecular dynamics studies of the phase behavior of liquid metals, which (a) utilize thermodynamic properties computed using our quantum mechanical calculations and (b) establish material and wetting properties of the liquid metals, including relevant eutectics, (iii) experimental investigations of the surface science of liquid metals, interacting both with the solid substrate as well as gaseous species, and (iv) fluid dynamical studies that incorporate the material and surface science results of (ii) and (iii) in order to characterize flow in capillary porous materials and the thin-film flow along curved boundaries, both of which are potentially major components of plasma-facing materials. The outcome of these integrated studies was new understanding that enables developing design rules useful for future developments of the plasma-facing components critical to the success of fusion energy systems.« less

2018-07-01
The present study aims to investigate the impact of help-seeking self-stigma on the preference and intention to seek psychological treatment delivered online compared to face-to-face. This study uses survey data from two Swedish samples. Sample 1 consists of 267 students (78.7% women) with a mean age of 24.5 (SD = 6.1). Sample 2 consists of 195 primary care patients (56.9% women) with a mean age of 45.3 (SD = 17.7). The number of participants who preferred online treatment was higher if seeking psychological help for a perceived stigmatized problem compared to mental health problems in general. The odds ratios for choosing treatment online over face-to-face were 6.41, 95% CI [4.05, 10.14] in Sample 1 and 11.19, 95% CI [5.29, 23.67] in Sample 2. In addition, findings suggest that higher levels of help-seeking self-stigma predicted higher intention to seek treatment online compared to face-to-face. Our results suggest that online interventions may facilitate help-seeking among individuals deterred by stigma. © 2018 Wiley Periodicals, Inc.

In this paper,we address the face sketch recognition problem. Firstly, we utilize the eigenface algorithm to convert a sketch image into a synthesized sketch face image. Subsequently, considering the low-level vision problem in synthesized face sketch image .Super resolution reconstruction algorithm based on CNN(convolutional neural network) is employed to improve the visual effect. To be specific, we uses a lightweight super-resolution structure to learn a residual mapping instead of directly mapping the feature maps from the low-level space to high-level patch representations, which making the networks are easier to optimize and have lower computational complexity. Finally, we adopt LDA(Linear Discriminant Analysis) algorithm to realize face sketch recognition on synthesized face image before super resolution and after respectively. Extensive experiments on the face sketch database(CUFS) from CUHK demonstrate that the recognition rate of SVM(Support Vector Machine) algorithm improves from 65% to 69% and the recognition rate of LDA(Linear Discriminant Analysis) algorithm improves from 69% to 75%.What'more,the synthesized face image after super resolution can not only better describer image details such as hair ,nose and mouth etc, but also improve the recognition accuracy effectively.
Finessing filter scarcity problem in face recognition via multi-fold filter convolution
NASA Astrophysics Data System (ADS)
Low, Cheng-Yaw; Teoh, Andrew Beng-Jin
2017-06-01
The deep convolutional neural networks for face recognition, from DeepFace to the recent FaceNet, demand a sufficiently large volume of filters for feature extraction, in addition to being deep. The shallow filter-bank approaches, e.g., principal component analysis network (PCANet), binarized statistical image features (BSIF), and other analogous variants, endure the filter scarcity problem that not all PCA and ICA filters available are discriminative to abstract noise-free features. This paper extends our previous work on multi-fold filter convolution (ℳ-FFC), where the pre-learned PCA and ICA filter sets are exponentially diversified by ℳ folds to instantiate PCA, ICA, and PCA-ICA offspring. The experimental results unveil that the 2-FFC operation solves the filter scarcity state. The 2-FFC descriptors are also evidenced to be superior to that of PCANet, BSIF, and other face descriptors, in terms of rank-1 identification rate (%).

The Fourier transform is used to reduce the linear plane problem of the tension of a body with an interfacial crack to a system of dual equations for the transformed stresses and, then, to a system of integro-differential equations for the difference of displacements of the crack faces. After discretization, this latter system transforms into a system of algebraic equations for displacements of the crack faces. The effect of the bielastic constant and the number of discretization points on the half-length of the crack faces and the distribution of stresses at the interface is studied
Clustering Millions of Faces by Identity.

Given a large collection of unlabeled face images, we address the problem of clustering faces into an unknown number of identities. This problem is of interest in social media, law enforcement, and other applications, where the number of faces can be of the order of hundreds of million, while the number of identities (clusters) can range from a few thousand to millions. To address the challenges of run-time complexity and cluster quality, we present an approximate Rank-Order clustering algorithm that performs better than popular clustering algorithms (k-Means and Spectral). Our experiments include clustering up to 123 million face images into over 10 million clusters. Clustering results are analyzed in terms of external (known face labels) and internal (unknown face labels) quality measures, and run-time. Our algorithm achieves an F-measure of 0.87 on the LFW benchmark (13 K faces of 5,749 individuals), which drops to 0.27 on the largest dataset considered (13 K faces in LFW + 123M distractor images). Additionally, we show that frames in the YouTube benchmark can be clustered with an F-measure of 0.71. An internal per-cluster quality measure is developed to rank individual clusters for manual exploration of high quality clusters that are compact and isolated.

This paper investigates a new control approach for longwall armored face conveyors (AFC`s) using variable-speed drives (VSD`s). Traditionally, AFC`s have used fixed-speed or two-speed motors, with various mechanical solutions employed to try to solve the problems that this causes. The VSD approach to the control problem promises to solve all the significant problems associated with the control of AFC`s. This paper will present the control algorithms developed for a VSD-based AFC drive system and demonstrate potential performance via computer simulation. A full discussion of the problems involved with the control of AFC`s can be found in the companion paper.

Integrating mathematics into science classrooms has been part of the conversation in science education for a long time. However, studies on student learning after incorporating mathematics in to the science classroom have shown mixed results. Understanding the mixed effects of including mathematics in science has been hindered by a historical focus on characteristics of integration tangential to student learning (e.g., shared elements, extent of integration). A new framework is presented emphasizing the epistemic role of mathematics in science. An epistemic role of mathematics missing from the current literature is identified: use of mathematics to represent scientific mechanisms, Mechanism Connected Mathematics (MCM). Building on prior theoretical work, it is proposed that having students develop mathematical equations that represent scientific mechanisms could elevate their conceptual understanding and quantitative problem solving. Following design and implementation of an MCM unit in inheritance, a large-scale quantitative analysis of pre and post implementation test results showed MCM students, compared to traditionally instructed students) had significantly greater gains in conceptual understanding of mathematically modeled scientific mechanisms, and their ability to solve complex quantitative problems. To gain insight into the mechanism behind the gain in quantitative problem solving, a small-scale qualitative study was conducted of two contrasting groups: 1) within-MCM instruction: competent versus struggling problem solvers, and 2) within-competent problem solvers: MCM instructed versus traditionally instructed. Competent MCM students tended to connect their mathematical inscriptions to the scientific phenomenon and to switch between mathematical and scientifically productive approaches during problem solving in potentially productive ways. The other two groups did not. To address concerns about teacher capacity presenting barriers to scalability of MCM approaches, the types and amount of teacher support needed to achieve these types of student learning gains were investigated. In the context of providing teachers with access to educative materials, students achieved learning gains in both areas in the absence of face-to-face teacher professional development. However, maximal student learning gains required the investment of face-to-face professional development. This finding can govern distribution of scarce resources, but does not preclude implementation of MCM instruction even where resource availability does not allow for face-to-face professional development.
Hybrid generative-discriminative approach to age-invariant face recognition

Sajid, Muhammad; Shafique, Tamoor
2018-03-01
Age-invariant face recognition is still a challenging research problem due to the complex aging process involving types of facial tissues, skin, fat, muscles, and bones. Most of the related studies that have addressed the aging problem are focused on generative representation (aging simulation) or discriminative representation (feature-based approaches). Designing an appropriate hybrid approach taking into account both the generative and discriminative representations for age-invariant face recognition remains an open problem. We perform a hybrid matching to achieve robustness to aging variations. This approach automatically segments the eyes, nose-bridge, and mouth regions, which are relatively less sensitive to aging variations compared with the rest of the facial regions that are age-sensitive. The aging variations of age-sensitive facial parts are compensated using a demographic-aware generative model based on a bridged denoising autoencoder. The age-insensitive facial parts are represented by pixel average vector-based local binary patterns. Deep convolutional neural networks are used to extract relative features of age-sensitive and age-insensitive facial parts. Finally, the feature vectors of age-sensitive and age-insensitive facial parts are fused to achieve the recognition results. Extensive experimental results on morphological face database II (MORPH II), face and gesture recognition network (FG-NET), and Verification Subset of cross-age celebrity dataset (CACD-VS) demonstrate the effectiveness of the proposed method for age-invariant face recognition well.

Maximal likelihood correspondence estimation for face recognition across pose.
Li, Shaoxin; Liu, Xin; Chai, Xiujuan; Zhang, Haihong; Lao, Shihong; Shan, Shiguang
2014-10-01
Due to the misalignment of image features, the performance of many conventional face recognition methods degrades considerably in across pose scenario. To address this problem, many image matching-based methods are proposed to estimate semantic correspondence between faces in different poses. In this paper, we aim to solve two critical problems in previous image matching-based correspondence learning methods: 1) fail to fully exploit face specific structure information in correspondence estimation and 2) fail to learn personalized correspondence for each probe image. To this end, we first build a model, termed as morphable displacement field (MDF), to encode face specific structure information of semantic correspondence from a set of real samples of correspondences calculated from 3D face models. Then, we propose a maximal likelihood correspondence estimation (MLCE) method to learn personalized correspondence based on maximal likelihood frontal face assumption. After obtaining the semantic correspondence encoded in the learned displacement, we can synthesize virtual frontal images of the profile faces for subsequent recognition. Using linear discriminant analysis method with pixel-intensity features, state-of-the-art performance is achieved on three multipose benchmarks, i.e., CMU-PIE, FERET, and MultiPIE databases. Owe to the rational MDF regularization and the usage of novel maximal likelihood objective, the proposed MLCE method can reliably learn correspondence between faces in different poses even in complex wild environment, i.e., labeled face in the wild database.

2015-01-01
Background/Objective: Osteoarthritis (OA) is a highly prevalent condition worldwide. Yoga is potentially a safe and feasible option for managing OA; however, the extent of long-term yoga adherence is unknown. The purpose of this study was to examine yoga adherence 6 months after participants completed an OA intervention program. Methods: This follow-up study employed a cross-sectional descriptive design using survey, interview, and video recordings to collect both quantitative and qualitative data. A total of 31 participants completed and returned the survey, and 10 videotaped their yoga practice for 1 week and participated in a face-to-face interview. Results: A majority of participants (n=19, 61%) reported that they were still practicing yoga 6 months after the intervention program. On average, participants reported practicing 21 to 30 minutes of yoga per day (32%) 3 to 4 days per week (47%). “Feeling good or feeling better after yoga practice” (50%) and “set aside a time” (31%) were the most common motivating factors for yoga adherence. Dealing with health problems (42%), having pain (25%), and being too busy (25%) were the major barriers. Qualitative data revealed that participants: (1) used mindful yoga movement, (2) incorporated other forms of exercise and resources during yoga practice, and (3) created personalized yoga programs. Additionally, the participants reported less OA pain, increased physical endurance, and more relaxation. Conclusion: Many participants adhered to yoga practice 6 months post-intervention although not at the frequency and sequence as prescribed. Feeling better after practice motivated participants, but other factors remained key barriers. PMID:25984414

The data were collected via a "Personal Information Form" which included 30 questions that were prepared by the researchers themselves in line with the literature. The data were collected by face to face interviews with the mothers. Analyses were performed using commercial software. The mean age of the mothers who participated in the study was 32.0 ± 6.52, and 88.1% reported no information about HPV, and 83.5% no information about HPV vaccination. Only 0.7% of the mothers had daughters who had HPV vaccination, and 44.3% of the mothers who had sons were found out to be indecisive about having HPV vaccination. There was a significant corelation between the educational status of the mothers and their knowledge about HPV vaccination (p<0.05). However, there was no significant correlation in terms of economic conditions (p>0.05). This study suggested that mothers had very little information on HPV and HPV vaccination. Knowledge of the disease and its vaccination is an essential factor for the success of the vaccination program. It is of great importance that mothers are trained in this subject by health professionals.
Characterizing the Last Latrine Nonowners in Rural Malawi.
Slekiene, Jurgita; Mosler, Hans-Joachim

Open defecation is a public health problem worldwide. Non-governmental organizations in developing countries use various approaches to increase latrine coverage, but for little-understood reasons, some of the population does not adopt latrine construction. The objective of our research was to uncover which of the factors predicting latrine construction are relevant to the last nonowners of latrines, termed laggards in the diffusion of innovations theory. In a cross-sectional study, quantitative face-to-face interviews were conducted in households in rural Malawi ( N = 824) to assess the behavioral determinants of latrine construction, mental health, and leadership. Around 14% of the households interviewed did not own a latrine. Study results suggest that nonowners have limited economic resources and perceive that latrine construction is expensive, that it is difficult to find money for latrine construction, and that it needs a lot of time and effort. The last nonowners of latrines live in smaller groups than latrine owners, communicate less with others about latrine construction, and are less influenced by the opinion of their leaders. They consist, in particular, of socially vulnerable households, are younger, are less educated, often have more impaired mental health, feel more vulnerable to contracting diseases, are less aware of the latrine construction of others in the village, feel less personally obliged to construct their own latrines, and are less confident in their ability to rebuild latrines damaged by flooding. The study confirmed that the assumptions of the diffusion of innovation theory are useful in combination with the risks, attitudes, norms, abilities, and self-regulation behavior change approach for developing evidence-based behavior change strategies in developing countries.

Abstract Purpose of the study Problem-solving therapy (PST) has been found effective when delivered to informal caregivers of patients with various conditions. In hospice, however, its translation to practice is impeded by the increased resources needed for its delivery. The study purpose was to compare the effectiveness of a PST intervention delivered face-to-face with one delivered via videophone to hospice primary caregivers. Design and methods The study design was a randomized noninferiority trial with two groups, Group 1 in which caregivers received PST face-to-face, and Group 2 in which caregivers received PST via videophone. Family hospice caregivers were recruited from two urban hospice agencies and received the PST intervention (in three visits for Group 1 or three video-calls in Group 2) in an approximate period of 20 days after hospice admission. Standard caregiver demographic data were collected. Psychometric instruments administered to caregivers at baseline and at study completion included the CQLI-R (Caregiver Quality of Life Index–Revised), the STAI (State-Trait Anxiety Inventory), and the PSI (Problem-Solving Inventory). Results One hundred twenty-six caregivers were recruited in the study; 77 were randomly assigned to Group 1 and 49 to Group 2. PST delivered via video was not inferior to face-to-face delivery. The observed changes in scores were similar for each group. Caregiver quality of life improved and state anxiety decreased under both conditions. Conclusions The delivery of PST via videophone was not inferior to face-to-face. Audiovisual feedback captured by technology may be sufficient, providing a solution to the geographic barriers that often inhibit the delivery of these types of interventions to older adults in hospice.

Dermatologic problems of the face affect both function and aesthetics, which are based on complex anatomical features. Treating dermatologic problems while preserving the aesthetics and functions of the face requires knowledge of normal anatomy. When performing successfully invasive procedures of the face, it is essential to understand its underlying topographic anatomy. This chapter presents the anatomy of the facial musculature and neurovascular structures in a systematic way with some clinically important aspects. We describe the attachments of the mimetic and masticatory muscles and emphasize their functions and nerve supply. We highlight clinically relevant facial topographic anatomy by explaining the course and location of the sensory and motor nerves of the face and facial vasculature with their relations. Additionally, this chapter reviews the recent nomenclature of the branching pattern of the facial artery. © 2013 Elsevier Inc. All rights reserved.
Epidemiology of whooping cough & typing of Bordetella pertussis.
Hegerle, Nicolas; Guiso, Nicole
2013-11-01
Bordetella pertussis is a Gram-negative human-restricted bacterium that evolved from the broad-range mammalian pathogen, Bordetella bronchiseptica. It causes whooping cough or pertussis in humans, which is the most prevalent vaccine-preventable disease worldwide. The introduction of the pertussis whole-cell vaccination for young children, followed by the introduction of the pertussis acellular vaccination (along with booster vaccination) for older age groups, has affected the bacterial population and epidemiology of the disease. B. pertussis is relatively monomorphic worldwide, but nevertheless, different countries are facing different epidemiological evolutions of the disease. Although it is tempting to link vaccine-driven phenotypic and genotypic evolution of the bacterium to epidemiology, many other factors should be considered and surveillance needs to continue, in addition to studies investigating the impact of current clinical isolates on vaccine efficacy.

ESA space spin-offs benefits for the health sector
NASA Astrophysics Data System (ADS)
Szalai, Bianca; Detsis, Emmanouil; Peeters, Walter
2012-11-01
Humanity will be faced with an important number of future challenges, including an expansion of the lifespan, a considerable increase of the population (estimated 9 billion by 2050) and a depletion of resources. These factors could trigger an increase of chronic diseases and various other health concerns that would bear a heavy weight on finances worldwide. Scientific advances can play an important role in solving a number of these problems, space technology; in general, can propose a panoply of possible solutions and applications that can make life on Earth easier and better for everyone. Satellites, Earth Observation, the International Space Station (ISS) and the European Space Agency (ESA) may not be the first tools that come to mind when thinking of improving health, yet there are many ways in which ESA and its programmes contribute to the health care arena. The research focuses on quantifying two ESA spin-offs to provide an initial view on how space can contribute to worldwide health. This quantification is part of the present strategy not only to show macroeconomic return factors for space in general, but also to identify and describe samples of 'best practice' type of examples close to the general public's interest. For each of the 'best practices' the methodology takes into account the cost of the space hardware/software, a number of tangible and intangible benefits, as well as some logical assumptions in order to determine the potential overall returns. Some of the hindering factors for a precise quantification are also highlighted. In conclusion, the study recommends a way in which ESA's spin-offs can be taken into account early on in the development process of space programmes in order to generate higher awareness with the general public and also to provide measurable returns.

The primary purpose of this study is to evaluate the relative effectiveness of 2 of the best developed and most promising forms of therapy for problem gambling, namely face-to-face motivational interviewing (MI) combined with a self-instruction booklet (W) and follow-up telephone booster sessions (B; MI+W+B) and face-to-face cognitive-behavioural therapy (CBT). This project is a single-blind pragmatic randomised clinical trial of 2 interventions, with and without the addition of relapse-prevention text messages. Trial assessments take place pretreatment, at 3 and 12 months. A total of 300 participants will be recruited through a community treatment agency that provides services across New Zealand and randomised to up to 10 face-to-face sessions of CBT or 1 face-to-face session of MI+W+up to 5 B. Participants will also be randomised to 9 months of postcare text messaging. Eligibility criteria include a self-perception of having a current gambling problem and a willingness to participate in all components of the study (eg, read workbook). The statistical analysis will use an intent-to-treat approach. Primary outcome measures are days spent gambling and amount of money spent per day gambling in the prior month. Secondary outcome measures include problem gambling severity, gambling urges, gambling cognitions, mood, alcohol, drug use, tobacco, psychological distress, quality of life, health status and direct and indirect costs associated with treatment. The research methods to be used in this study have been approved by the Ministry of Health, Health and Disability Ethics Committees (HDEC) 15/CEN/99. The investigators will provide annual reports to the HDEC and report any adverse events to this committee. Amendments will also be submitted to this committee. The results of this trial will be submitted for publication in peer-reviewed journals and as a report to the funding body. Additionally, the results will be presented at national and international conferences. ACTRN12615000637549. Published by the BMJ Publishing Group Limited.

Two personalized substance abuse assessment and feedback interventions were tested for effectiveness in engaging female domestic violence shelter residents in substance abuse treatment. One hundred forty-seven residents were assessed for quantity andfrequency of substance use, negative consequences due to use, motivation to change substance use behavior, and psychopathological symptoms related to substance abuse. Assessment identified (33) 22% of participants as heavy substance users. Twenty of the 33 heavy-using residents received one of two personalized substance use feedback interventions:face-to-face feedback or writtenfeedbackplaced in shelter mailboxes. Treatment engagement was defined as attending at least one substance abuse treatment session within 30 days after the intervention. Results showed a significant difference in treatment engagement rates in favor of the face-to-face feedback group (60% vs. 0%). The results provide preliminary data suggesting that substance abuse assessment can be effectively accomplished in the shelter environment and that the face-to-face feedback procedure may be an effective intervention to bridge the service linkage problem between domestic violence services and substance abuse treatment.
Ethnicity identification from face images

Lu, Xiaoguang; Jain, Anil K.

Human facial images provide the demographic information, such as ethnicity and gender. Conversely, ethnicity and gender also play an important role in face-related applications. Image-based ethnicity identification problem is addressed in a machine learning framework. The Linear Discriminant Analysis (LDA) based scheme is presented for the two-class (Asian vs. non-Asian) ethnicity classification task. Multiscale analysis is applied to the input facial images. An ensemble framework, which integrates the LDA analysis for the input face images at different scales, is proposed to further improve the classification performance. The product rule is used as the combination strategy in the ensemble. Experimental results based on a face database containing 263 subjects (2,630 face images, with equal balance between the two classes) are promising, indicating that LDA and the proposed ensemble framework have sufficient discriminative power for the ethnicity classification problem. The normalized ethnicity classification scores can be helpful in the facial identity recognition. Useful as a "soft" biometric, face matching scores can be updated based on the output of ethnicity classification module. In other words, ethnicity classifier does not have to be perfect to be useful in practice.
Person Authentication Using Learned Parameters of Lifting Wavelet Filters
NASA Astrophysics Data System (ADS)
Niijima, Koichi
2006-10-01
This paper proposes a method for identifying persons by the use of the lifting wavelet parameters learned by kurtosis-minimization. Our learning method uses desirable properties of kurtosis and wavelet coefficients of a facial image. Exploiting these properties, the lifting parameters are trained so as to minimize the kurtosis of lifting wavelet coefficients computed for the facial image. Since this minimization problem is an ill-posed problem, it is solved by the aid of Tikhonov's regularization method. Our learning algorithm is applied to each of the faces to be identified to generate its feature vector whose components consist of the learned parameters. The constructed feature vectors are memorized together with the corresponding faces in a feature vectors database. Person authentication is performed by comparing the feature vector of a query face with those stored in the database. In numerical experiments, the lifting parameters are trained for each of the neutral faces of 132 persons (74 males and 58 females) in the AR face database. Person authentication is executed by using the smile and anger faces of the same persons in the database.
Tensor discriminant color space for face recognition.
Wang, Su-Jing; Yang, Jian; Zhang, Na; Zhou, Chun-Guang
2011-09-01
Recent research efforts reveal that color may provide useful information for face recognition. For different visual tasks, the choice of a color space is generally different. How can a color space be sought for the specific face recognition problem? To address this problem, this paper represents a color image as a third-order tensor and presents the tensor discriminant color space (TDCS) model. The model can keep the underlying spatial structure of color images. With the definition of n-mode between-class scatter matrices and within-class scatter matrices, TDCS constructs an iterative procedure to obtain one color space transformation matrix and two discriminant projection matrices by maximizing the ratio of these two scatter matrices. The experiments are conducted on two color face databases, AR and Georgia Tech face databases, and the results show that both the performance and the efficiency of the proposed method are better than those of the state-of-the-art color image discriminant model, which involve one color space transformation matrix and one discriminant projection matrix, specifically in a complicated face database with various pose variations.

Prevention of mental disorders worldwide requires a greater understanding of protective processes associated with lower levels of mental health problems in children who face pervasive life stressors. This study aimed to identify culturally appropriate indicators of individual-level protective factors in Rwandan adolescents where risk factors, namely poverty and a history of trauma, have dramatically shaped youth mental health. The sample included 367 youth aged 10-17 in rural Rwanda. An earlier qualitative study of the same population identified the constructs "kwihangana" (patience/perseverance) and "kwigirira ikizere" (self-esteem) as capturing local perceptions of individual-level characteristics that helped reduce risks of mental health problems in youth. Nine items from the locally derived constructs were combined with 25 items from an existing scale that aligned well with local constructs-the Connor-Davidson Resilience Scale (CD-RISC). We assessed the factor structure of the CD-RISC expanded scale using exploratory factor analysis and determined the correlation of the expanded CD-RISC with depression and functional impairment. The CD-RISC expanded scale displayed high internal consistency (α = 0.93). Six factors emerged, which we labeled: perseverance, adaptability, strength/sociability, active engagement, self-assuredness, and sense of self-worth. Protective factor scale scores were significantly and inversely correlated with depression and functional impairment (r = -0.49 and r = - 0.38, respectively). An adapted scale displayed solid psychometric properties for measuring protective factors in Rwandan youth. Identifying culturally appropriate protective factors is a key component of research associated with the prevention of mental health problems and critical to the development of cross-cultural strength-based interventions for children and families.
[Drinking water supply in the Russian Federation: problems and ways of their solution].
Onishchenko, G G
2007-01-01
Russia having a fifth of the worldwide drinking water resources is faced with considerable difficulties in solving the problems associated with the safe and rational attitude towards water resources, in improving the technologies of drinking water purification and conditioning, in introducing new universal forms of supplying the population with high-quality portable water. Particular emphasis has been recently placed on the setting-up of an effective legal and normative base for the sanitary protection of water sources and the upgrading of the quality of drinking water. Regional (republican, territorial) drinking water supply programs have been worked out up to the period 2010 in 47 subjects of the Russian Federation, with the participation of sanitary-and-epidemiological surveillance systems and approved in accordance with the established procedures. The majority of administrative areas have district and town programs to implement high-priority measures for improving the water supple system. Safe drinking water supply is one of the major components of Russia's national security. Under the established conditions, even in case of the favorable financial position, this cannot be achieved by only engineering decisions (construction and modernization of water-supply networks, use of new equipment and breakthrough technologies). Water service as a type of water consumption is based on the general principles of natural resource management. Its safety should be combined with the strategic objective of water resources utilization and conservation in the catchment basins in the country as a whole.
Micronutrient status and intervention programs in Malaysia.
Khor, Geok Lin
2005-06-01
Approximately 70% of the world's malnourished children live in Asia, giving that region the highest concentration of childhood malnutrition worldwide. Prevalence of stunting and underweight are high especially in south Asia where one in every two preschool children is stunted. Iron-deficiency anemia affects 40%-50% of preschool and primary schoolchildren. Nearly half of all vitamin A deficiency and xerophthalmia in the world occurs in south and southeast Asia. Iodine deficiency disorders have resulted in high goiter rates in India, Pakistan, and parts of Indonesia. Compared with other developing countries in Asia, the nutrition situation in Malaysia is considerably better, owing to rapid economic and socioeconomic development that has occurred since Malaysia gained its independence in 1957. Prevalence of undernutrition and micronutrient deficiency is markedly lower in Malaysian children. Nonetheless, undernutrition in the form of underweight, stunting, and anemia can be found in poor communities throughout the country. A prevalence of 25% underweight and 35% stunting is reported among young children from poor rural households. Anemia and subclinical forms of vitamin A deficiency were reported in children under 5 years old. Typical of a country in nutrition transition, Malaysia faces the dual burden of malnutrition in children, with the persistence of under-nutrition problems especially among the poor and the emerging overweight problem especially in urban areas. Since 1996, nutrition programs of the government sector are coordinated under the National Plan of Action for Nutrition. These activities and other nutrition intervention efforts by other agencies are discussed in this paper.
Arsenic Contaminated Groundwater and Its Treatment Options in Bangladesh

Arsenic (As) causes health concerns due to its significant toxicity and worldwide presence in drinking water and groundwater. The major sources of As pollution may be natural process such as dissolution of As-containing minerals and anthropogenic activities such as percolation of water from mines, etc. The maximum contaminant level for total As in potable water has been established as 10 µg/L. Among the countries facing As contamination problems, Bangladesh is the most affected. Up to 77 million people in Bangladesh have been exposed to toxic levels of arsenic from drinking water. Therefore, it has become an urgent need to provide As-free drinking water in rural households throughout Bangladesh. This paper provides a comprehensive overview on the recent data on arsenic contamination status, its sources and reasons of mobilization and the exposure pathways in Bangladesh. Very little literature has focused on the removal of As from groundwaters in developing countries and thus this paper aims to review the As removal technologies and be a useful resource for researchers or policy makers to help identify and investigate useful treatment options. While a number of technological developments in arsenic removal have taken place, we must consider variations in sources and quality characteristics of As polluted water and differences in the socio-economic and literacy conditions of people, and then aim at improving effectiveness in arsenic removal, reducing the cost of the system, making the technology user friendly, overcoming maintenance problems and resolving sludge management issues.

With the advance of internet and wireless communication technology, the fields of ecology and environment have entered a new digital era with the amount of data growing explosively and big data technologies attracting more and more attention. The eco-environmental big data is based airborne and space-/land-based observations of ecological and environmental factors and its ultimate goal is to integrate multi-source and multi-scale data for information mining by taking advantages of cloud computation, artificial intelligence, and modeling technologies. In comparison with other fields, the eco-environmental big data has its own characteristics, such as diverse data formats and sources, data collected with various protocols and standards, and serving different clients and organizations with special requirements. Big data technology has been applied worldwide in ecological and environmental fields including global climate prediction, ecological network observation and modeling, and regional air pollution control. The development of eco-environmental big data in China is facing many problems, such as data sharing issues, outdated monitoring facilities and techno-logies, and insufficient data mining capacity. Despite all this, big data technology is critical to solving eco-environmental problems, improving prediction and warning accuracy on eco-environmental catastrophes, and boosting scientific research in the field in China. We expected that the eco-environmental big data would contribute significantly to policy making and environmental services and management, and thus the sustainable development and eco-civilization construction in China in the coming decades.

To identify the problems faced by parents of children with developmental disabilities in availing rehabilitative services and to find their satisfaction level. This study was carried out at a Child Development Clinic (CDC) located in Northern India. Children with developmental disabilities, who were availing services at CDC for at least last 3 mo and had at least 3 follow-up visits, were enrolled. A questionnaire pertaining to the socio-demographic profile, problems faced in availing services and satisfaction level was filled by the parents of the enrolled children. During the study period, 161 parents filled the questionnaire. 77.6% had some problems in getting the services, the major being difficulty in commuting (50%) and financial constraint (21.7%). More than 80% parents use public transport to reach CDC with 19% travelling more than 50 Km. 29.8% had difficulty in bringing their child to the clinic, either due to severe behavioral problems or physical disability. However, majority of the families were well satisfied with the services as 95% of them graded their satisfaction level at 3 or more on the scale of 0-5. Parents of children with developmental disabilities face many problems in getting rehabilitative services. They travel long distances, face hardships in carrying their child, and lose their day's earnings, apart from spending time and money for their child's therapy. However, most of the parents are well satisfied with the services.

In real-world applications, the image of faces varies with illumination, facial expression, and poses. It seems that more training samples are able to reveal possible images of the faces. Though minimum squared error classification (MSEC) is a widely used method, its applications on face recognition usually suffer from the problem of a limited number of training samples. In this paper, we improve MSEC by using the mirror faces as virtual training samples. We obtained the mirror faces generated from original training samples and put these two kinds of samples into a new set. The face recognition experiments show that our method does obtain high accuracy performance in classification.

The purpose of the study is the evaluation of the numerical accuracy of FIDAP (Fluid Dynamics Analysis Package). Accordingly, four test problems in laminar and turbulent incompressible flows are selected and the computational results of these problems compared with other numerical solutions and/or experimental data. These problems include: (1) 2-D laminar flow inside a wall-driven cavity; (2) 2-D laminar flow over a backward-facing step; (3) 2-D turbulent flow over a backward-facing step; and (4) 2-D turbulent flow through a turn-around duct.
Pattern-process interactions at alpine treeline in southwest Yukon, Canada
NASA Astrophysics Data System (ADS)
Danby, R.
2011-12-01
Results from an ensemble of studies conduced in southwest Yukon have uncovered a distinct "top-down/bottom-up" interaction at alpine treeline whereby terrain-induced gradients of solar radiation result in fundamental differences in plant-scale biological processes which, in turn, structure vegetation pattern at the landscape scale. Varied insolation creates differences in snow depth and timing of melt, soil temperature, and permafrost on opposing slopes that result in distinct physiological differences in white spruce (Picea glauca), the dominant treeline conifer. Measurement of young individuals indicated that secondary growth and lateral growth was significantly greater on south-facing slopes. Photosynthetic efficiency was reduced in individuals on south-facing slopes, while over-winter damage and mortality was significantly greater. Population-level processes also differed. Dendroecology and repeat photography indicated that treeline advanced on south-facing slopes during the 20th century, but that range expansion was limited on north-facing slopes. These process-related differences appear to be the mechanism for differences in treeline pattern at the landscape scale, including a higher treeline elevation and greater clustering of individuals on south-facing slopes. These results can be used to inform theory on the functional causation of treeline, rationalize differential treeline dynamics observed worldwide, and better inform predictions of future treeline dynamics.

Microdermabrasion is a popular method for facial rejuvenation and is performed worldwide. Despite its extensive usage, there are few publications on skin barrier change after microdermabrasion and none concerning diamond microdermabrasion. Our object was to see changes in transepidermal water loss (TEWL), hydration and erythema of the face following diamond microdermabrasion. Twenty-eight patients were included in this spilt face study. TEWL, stratum corneum hydration and the degree of erythema were measured from the right and left sides of the face (forehead and cheek) at baseline. One side of the face was treated with diamond microdermabrasion and the other side was left untreated. Measurements were taken right after the procedure and repeated at set time intervals. Diamond microdermabrasion was associated with a statistically significant increase in TEWL immediately after the procedure and at 24 h. However, on day 2, levels of TEWL were back to baseline. An increase in hydration and erythema was observed right after microdermabrasion, but both returned to baseline on day 1. The results show that skin barrier function of the forehead and cheek recovers within 2 days of diamond microdermabrasion. Diamond microdermabrasion performed on a weekly basis, as presently done, is expected to allow sufficient time for the damaged skin to recover its barrier function in most parts of the face.

A number of interventions have been undertaken to develop and promote social networks among community-dwelling older adults. However, it has been difficult to examine the effects of these interventions, because of problems in assessing interactions. The present study was designed to quantitatively measure and visualize face-to-face interactions among elderly participants in an exercise program. We also examined relationships among interactional variables, personality and interest in community involvement, including interactions with the local community. Older adults living in the same community were recruited to participate in an exercise program that consisted of four sessions. We collected data on face-to-face interactions of the participants by using a wearable sensor technology device. Network analysis identified the communication networks of participants in the exercise program, as well as changes in these networks. Additionally, there were significant correlations between the number of people involved in face-to-face interactions and changes in both interest in community involvement and interactions with local community residents, as well as personality traits, including agreeableness. Social networks in the community are essential for solving problems caused by the aging society. We showed the possible applications of face-to-face interactional data for identifying core participants having many interactions, and isolated participants having only a few interactions within the community. Such data would be useful for carrying out efficient interventions for increasing participants' involvement with their community.

Recent advances in image and pattern recognition technology- -especially face recognition--are leading to the development of a new generation of information systems of great value to the law enforcement community. With these systems it is now possible to pool and manage vast amounts of biometric intelligence such as face and finger print records and conduct computerized searches on them. We review one of the enabling technologies underlying these systems: the FaceIt face recognition engine; and discuss three applications that illustrate its benefits as a problem-solving technology and an efficient and cost effective investigative tool.
HIV-related needs for safety among male-to-female transsexuals (mak nyah) in Malaysia.
Koon Teh, Yik
2008-12-01
This research, commissioned by the Malaysian AIDS Council in 2007, is qualitative and descriptive in nature. In depth face-to-face interviews were carried out with 15 mak nyah respondents from five major towns. The interviews were guided by an interview schedule that had seven main topics: brief background; hormone-taking behaviour; safe sex; health care; substance abuse; harassment from authorities; and HIV prevention. The HIV problem among the mak nyah, mak nyah sex workers and their clients is critical. Many do not have in-depth HIV/AIDS knowledge and do not practise safe sex. The problem gets worse when most mak nyah do not consider HIV/AIDS as a primary concern because of other pressing problems like employment and discrimination. There are also no HIV prevention activities in many parts of Malaysia. Mak nyah also face constant harassment from enforcement authorities for prostitution. This hampers HIV prevention work.

Determining paths by which farmers can adapt effectively to scarce freshwater resources

Stress on freshwater resources is a significant risk associated with climatic change. The risk is even greater given the expected changes in overall resource use as the developing world develops, as the world's population continues to grow, and as land use changes dramatically. Effective water management has implications for food security, health, and political stability worldwide. This is particularly true in developing regions heavily dependent on agriculture, and where agriculture depends on irrigation. Adaptation to water stress requires both managing water allocation among competing users and ensuring that each user is efficient in his or her use of a limited allotment: the problem is a quintessential common-pool resource (CPR) dilemma. In the future even more so than in the past, adaptation will be essential as the world evolves. The problem that we identify—determining paths by which farmers can adapt effectively to increasingly scarce freshwater resources—is one of great scientific and societal importance. The issue lies at the intersection of water-cycle processes and social-psychological processes that influence and are influenced by water availability and use. This intersection harbors intriguing unresolved scientific questions; advances in natural and social sciences will stem from attacks on the overall problem. The issue is societally compelling because the ability of the world to supply adequate food for a population expected to grow to over 9 billion by 2050 may well be determined by how farmers, consumers, and government institutions adapt to changing conditions of water availability. Major strides have been made in recent decades in understanding why Hardin's envisioned "tragedy of the commons" is avoided under certain circumstances, in some cases through self-organization rather than government intervention originally considered a necessity. Furthermore, we now know that the impacts of decisions about allocation and use of water can be amplified by human system-natural system feedbacks. Thus, although there are hard problems in many individual disciplines to be tackled, it is also clear that CPR problems cannot be understood, much less managed, without truly interdisciplinary approaches that recognize that human and natural systems are strongly coupled and that include this coupling in the research design and implementation. The problem of farmer adaptation is a specific instance of the challenge articulated by Ostrom in her Nobel Prize lecture: "We thus face the tough task of further developing our theories to help understand and predict when those involved in a common-pool resource dilemma will be able to self-organize and how various aspects of the broad context they face affect their strategies, the short-term success of their efforts, and the long-term robustness of their initial achievements." In this paper we discuss advances in recent understanding of irrigation water as a CPR and the linkages with individual behavior. Using our ongoing work in Sri Lanka to provide context, we also discuss gaps in this research as well as emerging problems warranting attention. We pay special attention to the role and necessity of integrated, interdisciplinary research and identify a framework for making further progress toward addressing the key problem of determining paths by which farmers can adapt effectively.

This was a cross-sectional study under taken to explore the socioeconomic perspective of the arsenicosis problem, carried out in arsenic contaminated Upazillas where at least 100 arsenicosis patients had been identified. Two of the Upazillas with significant arsenic mitigation intervention and three of the Upazillas with limited interventions were selected for the study. Seven hundred fifty respondents were included in the study from 25 villages of the 5 Upazillas. Arsenicosis became a serious problem for the affected communities. Majority (71.31%) of respondents obtained their drinking water from tubewells, almost one third (29%) of the respondents still knowingly using arsenic contaminated water. Primary reason identified for this practice was distance of safe water source. Majority (58.6%) of the respondents said to face economic and 17.9% said to face social problem of varied range. Patients of lower income group were particularly more likely to face economic problems (P< .001) as well as social problem (P< .01). About half (50.7%) of the arsenicosis patients faced difficulty whilst receiving treatment, particularly female patients were more likely to face problem than male (P< .05). Several concerns also were surfaced regarding the heath care service provider particularly to the women patients, some of which are: long waiting time for receiving treatment (15%), discrimination in service delivery (10.7%) and inadequate separate facility for female patients (14.3%). Moreover the issues of financial burden raised by the respondents seem to have emerged as significant in terms of health care access. Access to Health service was particularly difficult for poor patients, as they often had to face problems associated with accessing service like, non availability of medicines in the hospitals (50.7%), traveling long distance (26.7%), purchasing medicine in most cases (32.4%) etc. Their dissatisfaction was compounded by negligent behavior of health care staff and nature of treatment provided. Furthermore length of time needed for reversal of symptoms led to loosing faith on efficacy of treatment, which cascades to negligence of patient's part in seeking health care. Women are less likely to get treatment for arsenicosis than men (P< .01). As there appear to be specific difficulties for women particularly for poor women in accessing health care, social and cultural values make it difficult for them to attend to their own health needs and to travel to service providers. Study findings suggest that a significant proportion (79.9%) of arsenicosis patient was found to access alternative health care. This includes; Homeopath, village doctors, Kabiraj and local pharmacists. Respondents in high intervention Upazillas were significantly more likely to get treatment (P< .05), to face fewer problems and to be satisfied with the facility (P< .001). Provision of safe water options, periodic screening of water source for arsenic, availability of trained doctor, regular availability of medicine, doorstep treatment, follow up on severe patients were the suggestions came from community for improvement.

Pre-harvest aflatoxin contamination (PAC) is a major problem facing peanut production worldwide. Produced by the ubiquitous soil fungus, Aspergillus flavus, aflatoxin is the most naturally occurring known carcinogen. The interaction between fungus and host resulting in PAC is complex, and breeding for PAC resistance has been slow. It has been shown that aflatoxin production can be induced by applying drought stress as peanut seeds mature. We have implemented an automated rainout shelter that controls temperature and moisture in the root and peg zone to induce aflatoxin production. Using polymerase chain reaction (PCR) and high performance liquid chromatography (HPLC), seeds meeting the following conditions were selected: infected with Aspergillus flavus and contaminated with aflatoxin; and not contaminated with aflatoxin. RNA sequencing analysis revealed groups of genes that describe the transcriptional state of contaminated vs. uncontaminated seed. These data suggest that fatty acid biosynthesis and abscisic acid (ABA) signaling are altered in contaminated seeds and point to a potential susceptibility factor, ABR1, as a repressor of ABA signaling that may play a role in permitting PAC.

Due to explosive growth in technology and internet usage in the last few years, internet gaming disorder (IGD) has manifested as rapidly growing public health problem mainly affecting the teen and preteen population worldwide. It has a negative impact upon physical, psychological, social, and occupational functioning of the affected individual, often leading to severe consequences. It was only recently that it has been recognized as a separate diagnosable disorder in the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition. Not much data is available regarding the exact prevalence and the various sociodemographic, clinical, and other risk factors to identify the individuals vulnerable to develop this disorder, especially in the developing countries such as India. According to a recent report, India ranks 22 nd in the list of highest revenue-generating countries from gaming-related businesses, thus highlighting the magnitude of risk faced by Indian population. The aim of this review is to provide an insight about the disorder to identify the risk factors and clinical features, to understand the effect of IGD upon the psychological and physical health with a special focus on neural changes, and to provide information on the various upcoming preventive and treatment strategies.

Unconventional crude oil as heavy, extra heavy, bitumen, tight, and shale oils will meet 10% of worldwide needs for 2035, perhaps earlier. Petroleum companies will face problems concerning crude oil extraction, production, transport, and refining, and some of these are addressed by the use of surfactants and other chemicals. For example, water-in-crude oil emulsions are frequently found during the production of mature wells where enhanced recovery techniques have been deployed. Nevertheless, the selection of adequate surfactant, dosage, type of water (sea, tap or oilfield), kind of crude oil (light, heavy, extra heavy, tight, shale, bitumen) affect the effectivity of treatment and usual bottle tests give limited information. We developed a fluorescence technique to study the effect of surfactants on medium, heavy, and extra heavy crude oil employing the natural fluorophore molecules from petroleum. We first carried out the characterization of commercial and synthetic surfactants, then dispersions of petroleum in water were studied by steady-state fluorometry and the size of petroleum aggregates were measured. The aggregation of petroleum incremented from medium to extra heavy crude oil and we discussed the effect of different surfactants on such aggregation.

Every year, epidemics of viral bronchiolitis and gastroenteritis occur with a significant increase in the number of visits (by a factor 1.8) and hospitalisations that can over-exceed bed capacity leading to transfer sick children to other hospitals. This kind of hospital 'crisis' is not limited to paediatrics, big cities or western nations. It is a worldwide worrying problem. Because our hospital sits in the Northern districts of Paris where a large community of m.ncants lives in poverty, our number of visits is high (mean 250 per day), and winter epidemics further jeopardise the difficult equilibrium achieved between quality management and waiting times. Thus, we have taken various initiatives in terms of organisation of the paediatric emergency department and other wards, including a "fast track" clinic, the opening of beds dedicated to winter epidemics, the institution of a "bed manager" in order to more easily find a bed, and a larger use of home hospitalisations. Furthermore, we created a specific committee which may decide on various indicators of tension whether it is necessary to cancel programmed hospitalisations or surgery.in order to resolve the emergency crisis. This kind of organisation can serve as a model for other hospitals facing winter epidemics crises.
Nosema ceranae (Microsporidia), a controversial 21st century honey bee pathogen.

The worldwide beekeeping sector has been facing a grave threat, with losses up to 100-1000 times greater than those previously reported. Despite the scale of this honey bee mortality, the causes underlying this phenomenon remain unclear, yet they are thought to be multifactorial processes. Nosema ceranae, a microsporidium recently detected in the European bee all over the world, has been implicated in the global phenomenon of colony loss, although its role remains controversial. A review of the current knowledge about this pathogen is presented focussing on discussion related with divergent results, trying to analyse the differences specially based on different methodologies applied and divisive aspects on pathology while considering a biological or veterinarian point of view. For authors, the disease produced by N. ceranae infection cannot be considered a regional problem but rather a global one, as indicated by the wide prevalence of this parasite in multiple hosts. Not only does this type of nosemosis causes a clear pathology on honeybees at both the individual and colony levels, but it also has significant effects on the production of honeybee products. © 2012 Society for Applied Microbiology and Blackwell Publishing Ltd.

The implementation of reverse logistics systems (RLS) for post-consumer products provides environmental and economic benefits, since it increases recycling potential. However, RLS implantation and consolidation still face problems. The main shortcomings are the high costs and the low expectation of broad implementation worldwide. This paper presents two mathematical models to decide the number and the location of screening centers (SCs) and valorization centers (VCs) to implement reverse logistics of post-consumer packages, defining the optimum territorial arrangements (OTAs), allowing the inclusion of small and medium size municipalities. The paper aims to fill a gap in the literature on RLS location facilities that not only aim at revenue optimization, but also the participation of the population, the involvement of pickers and the service universalization. The results showed that implementation of VCs can lead to revenue/cost ratio higher than 100%. The results of this study can supply companies and government agencies with a global view on the parameters that influence RLS sustainability and help them make decisions about the location of these facilities and the best reverse flows with the social inclusion of pickers and serving the population of small and medium-sized municipalities.

Rusu, Lazar; Lin, Yifeng; Hodosi, Georg
Worldwide job market for database developers (DBDs) is continually increasing in last several years. In some companies, DBDs are organized as a special team (DBDs team) to support other projects and roles. As a new role, the DBDs team is facing a major problem that there are not any management guidelines for them. The team manager does not know which kinds of tasks should be assigned to this team and what practices should be used during DBDs work. Therefore in this paper we have developed a set of management guidelines, which includes 8 fundamental tasks and 17 practices from software development process, by using two methodologies Capability Maturity Model (CMM) and agile software development in particular Scrum in order to improve the DBDs team work. Moreover the management guidelines developed here has been complemented with practices from authors' experience in this area and has been evaluated in the case of a software company. The management guidelines for DBD teams presented in this paper could be very usefully for other companies too that are using a DBDs team and could contribute towards an increase of the efficiency of these teams in their work on software development projects.

Plants have developed diverse defence mechanisms to ward off herbivorous pests. However, agriculture still faces estimated crop yield losses ranging from 25% to 40% annually. These losses arise not only because of direct feeding damage, but also because many pests serve as vectors of plant viruses. Herbivorous thrips (Thysanoptera) are important pests of vegetable and ornamental crops worldwide, and encompass virtually all general problems of pests: they are highly polyphagous, hard to control because of their complex lifestyle, and they are vectors of destructive viruses. Currently, control management of thrips mainly relies on the use of chemical pesticides. However, thrips rapidly develop resistance to these pesticides. With the rising demand for more sustainable, safer, and healthier food production systems, we urgently need to pinpoint the gaps in knowledge of plant defences against thrips to enable the future development of novel control methods. In this review, we summarize the current, rather scarce, knowledge of thrips-induced plant responses and the role of phytohormonal signalling and chemical defences in these responses. We describe concrete opportunities for breeding resistance against pests such as thrips as a prototype approach for next-generation resistance breeding.

Asia and the Pacific represent a diverse group of nations facing HIV epidemic profiles of differing severity. Compared to other parts of the world, the burden of HIV disease is high in this region because of its large populations. At the end of 2011, 5million people were living with HIV in Asia and the Pacific. This accounted for 15% of people living with HIV worldwide. The prevalence of people living with HIV, as well as access to HIV treatment and care, varies widely between countries. Differences between high-income economies and the rest of the continent are remarkable. Many high-income countries provide antiretroviral therapy (ART) to their citizens. Middle- and low-income countries have rapid ART scale-up and are dependent on international funding. This may compromise the sustainability of ART availability. In addition, lack of access to second- and third-line therapy remains a problem in many countries. The global goal of achieving universal access to ART by 2015 requires mainly low- and middle-income countries to be targeted. Regional policy should be developed in order to identify new infections in key populations, to start earlier treatment, to retain patients in care and to maintain funding.
Analysis of the Pricing Process in Electricity Market using Multi-Agent Model
NASA Astrophysics Data System (ADS)
Shimomura, Takahiro; Saisho, Yuichi; Fujii, Yasumasa; Yamaji, Kenji
Many electric utilities world-wide have been forced to change their ways of doing business, from vertically integrated mechanisms to open market systems. We are facing urgent issues about how we design the structures of power market systems. In order to settle down these issues, many studies have been made with market models of various characteristics and regulations. The goal of modeling analysis is to enrich our understanding of fundamental process that may appear. However, there are many kinds of modeling methods. Each has drawback and advantage about validity and versatility. This paper presents two kinds of methods to construct multi-agent market models. One is based on game theory and another is based on reinforcement learning. By comparing the results of the two methods, they can advance in validity and help us figure out potential problems in electricity markets which have oligopolistic generators, demand fluctuation and inelastic demand. Moreover, this model based on reinforcement learning enables us to consider characteristics peculiar to electricity markets which have plant unit characteristics, seasonable and hourly demand fluctuation, real-time regulation market and operating reserve market. This model figures out importance of the share of peak-load-plants and the way of designing operating reserve market.
Evaluation of greenhouse gas emissions from waste management approaches in the islands.
Chen, Ying-Chu
2017-07-01
Concerns about waste generation and climate change have attracted worldwide attention. Small islands, which account for more than one-sixth of the global land area, are facing problems caused by global climate change. This study evaluated the greenhouse gas emissions from five small islands surrounding Taiwan. These islands - Penghu County, Liuqui Island, Kinmen County, Matsu Island and Green Island - have their own waste management approaches that can serve as a guideline for waste management with greenhouse gas mitigation. The findings indicate that the total annual greenhouse gas emissions of the islands ranged from 292.1 to 29,096.2 [metric] tonne CO 2 -equivalent. The loading waste volumes and shipping distances were positively related to greenhouse gas emissions from transportation. The greenhouse gas emissions from waste-to-energy plants, mainly carbon dioxide and nitrous oxide, can be offset by energy recovery (approximately 38.6% of greenhouse gas emissions from incineration). In addition, about 34% and 11% of waste generated on the islands was successfully recycled and composted, respectively. This study provides valuable insights into the applicability of a policy framework for waste management approaches for greenhouse gas mitigation.

Most accounts of the ethical problems facing researchers across a broad spectrum of research fields come from ethicists, ethics committees, and specialists committed to the study of ethics in human research. In contrast, this study reports on the ethical questions that researchers, themselves, report facing in their everyday practice. Fifty-five Swedish researchers contributed 109 examples of ethical dilemmas, conflicts, and problems in research. They were all researchers at the postdoctoral level in the fields of medicine, the humanities, education, and the social sciences, who devoted at least 50 percent of their working hours to research. They reported issues they face before, during, and after gathering data. Their range of issues is broader than generally discussed and points to the importance of researchers' ethical sensitivity.

Family caregivers of persons with advanced cancer often take on responsibilities that present daunting and complex problems. Serious problems that go unresolved may be burdensome and result in negative outcomes for caregivers' psychological and physical health and affect the quality of care delivered to the care recipients with cancer, especially at the end of life. Formal problem-solving training approaches have been developed over the past several decades to assist individuals with managing problems faced in daily life. Several of these problem-solving principles and techniques were incorporated into ENABLE (Educate, Nurture, Advise, Before Life End), an "early" palliative care telehealth intervention for individuals diagnosed with advanced cancer and their family caregivers. A hypothetical case resembling the situations of actual caregiver participants in ENABLE that exemplifies the complex problems that caregivers face is presented, followed by presentation of an overview of ENABLE's problem-solving key principles, techniques, and steps in problem-solving support. Though more research is needed to formally test the use of problem-solving support in social work practice, social workers can easily incorporate these techniques into everyday practice.

Resource managers often face significant information technology (IT) problems when integrating ecological or environmental information to make decisions. At a workshop sponsored by the NSF and USGS in December 2004, university researchers, natural resource managers, and information managers met to articulate IT problems facing ecology and environmental decision makers. Decision making IT problems were identified in five areas: 1) policy, 2) data presentation, 3) data gaps, 4) tools, and 5) indicators. To alleviate those problems, workshop participants recommended specific informatics research in modeling and simulation, data quality, information integration and ontologies, and social and human aspects. This paper reports the workshop findings, and briefly compares these with research that traditionally falls under the emerging eco-informatics rubric. ?? Springer-Verlag Berlin Heidelberg 2005.

Prevalence of atopic dermatitis (AD) is increasing worldwide. Up to date, there has been no face-to-face nation-wide study in China. We aim to explore the prevalence of clinical diagnosed AD in children aged 1–7 ys in China. Twelve metropolises were chosen from different areas of China. In each region, we selected 4–10 kindergartens and 2–5 vaccination clinics randomly. A complete history-taking and skin examination were performed by dermatologists. The definite diagnosis of AD and the severity were determined by two or three dermatologists. All criteria concerned in UK diagnosis criteria, characteristic presentation of AD and atypical manifestations were recorded in detail. A total of 13998 children from 84 kindergartens and 40 vaccination clinics were included. The prevalence of AD was 12.94% by clinical diagnosis of dermatologists overall, with 74.6% of mild AD. Comparatively, prevalence of AD based on UK diagnostic criteria was 4.76%. This is the first face-to-face nation-wide study in Chinese children aged 1–7 ys, revealing that the prevalence of AD in children is closer to that of wealthier nations. PMID:27432148
Pose Invariant Face Recognition Based on Hybrid Dominant Frequency Features
NASA Astrophysics Data System (ADS)
Wijaya, I. Gede Pasek Suta; Uchimura, Keiichi; Hu, Zhencheng
Face recognition is one of the most active research areas in pattern recognition, not only because the face is a human biometric characteristics of human being but also because there are many potential applications of the face recognition which range from human-computer interactions to authentication, security, and surveillance. This paper presents an approach to pose invariant human face image recognition. The proposed scheme is based on the analysis of discrete cosine transforms (DCT) and discrete wavelet transforms (DWT) of face images. From both the DCT and DWT domain coefficients, which describe the facial information, we build compact and meaningful features vector, using simple statistical measures and quantization. This feature vector is called as the hybrid dominant frequency features. Then, we apply a combination of the L2 and Lq metric to classify the hybrid dominant frequency features to a person's class. The aim of the proposed system is to overcome the high memory space requirement, the high computational load, and the retraining problems of previous methods. The proposed system is tested using several face databases and the experimental results are compared to a well-known Eigenface method. The proposed method shows good performance, robustness, stability, and accuracy without requiring geometrical normalization. Furthermore, the purposed method has low computational cost, requires little memory space, and can overcome retraining problem.

This study assessed the secondary effects of a parent training intervention program on maternal adjustment, with a focus on understanding ways in which program efficacy differed for participants as a function of whether or not their children had behavior problems. Mothers (N = 99) of toddlers (2-3 years of age) were randomly assigned to receive one of three levels of intervention: (1) informational booklet (2) booklet + face-to-face parent training sessions, or (3) booklet + web-based parent training sessions. Findings indicated that all levels of intervention were associated with increases in maternal well-being for participants with typically developing children. Mothers of toddlers with behavior problems, however, did not benefit from receiving only the booklet but significantly benefitted from receiving either the face-to-face or web-based interventions. Findings are discussed in terms of efficient and efficacious program dissemination and the resulting implications for public policy.
"Live Chat" Clients at Kids Help Phone: Individual Characteristics and Problem Topics.

Young people in Canada prefer to use the Internet over face-to-face contact when seeking help for problems of daily living and mental health problems. Kids Help Phone (KHP) provides on-demand, anonymous help to young people via telephone and Live Chat technologies. Two hundred thirty-two phone clients and 230 Live Chat clients responded to a questionnaire at this otherwise anonymous service, providing previously inaccessible data about their individual characteristics and characterizations of the problems for which they sought help. There was a larger proportion of weighty problems (mental health and suicide) among chatters than callers. There were also more non-heterosexual youth, and those who identified as Asian and Black African or Caribbean, using Live Chat than phone. Implications for training Live Chat counsellors to respond effectively to chatters are discussed.
Evaluation of Knowledge Development in a Healthcare Setting

Healthcare organizations worldwide have recently increased efforts to improve performance, quality, and knowledge transfer using information and communication technologies. Evaluation of the effectiveness and quality of such efforts is challenging. A macro and micro-level system evaluation conducted with a 14000 member US hospital administrative services organization examined the appropriateness of a blended face-to-face and technology-enabled performance improvement and knowledge development system. Furthermore, a successful team or microsystem in a high performing hospital was studied in-depth. Several types of data methods including interview, observation, and questionnaire were used to address evaluation questions within a knowledge development framework created for the study. Results of this preliminary study focus on how this organization attempted to organize clinical improvement efforts around quality and performance improvement processes supported by networked technologies.
Mechanics of gravitational spreading of steep-sided ridges («sackung»)
Savage, W.Z.; Varnes, D.J.
1987-01-01
Large-scale gravitational spreading of steep-sided ridges characterized by linear fissures, trenches, and uphill-facing scarps high on the sides and tops of ridges are known worldwide. Such spreading, termed sackung, is commonly attributed to pervasive plastic deformation of a rock mass, and is here analyzed as such. Beginning with a previously developed exact elastic solution for gravity-induced stresses in a symmetric ridge, stresses calculated from the exact solution are used in the Coulomb failure criterion to determine the extent of ridge failure under self-weight. Finally, when the regions of failure are established, a plastic flow solution is applied to predict the location of and sense of movement on upward-facing scarps near ridge crests and other features common in sackung. ?? 1987 International Assocaition of Engineering Geology.

Tools for Protecting the Privacy of Specific Individuals in Video
NASA Astrophysics Data System (ADS)
Chen, Datong; Chang, Yi; Yan, Rong; Yang, Jie
2007-12-01
This paper presents a system for protecting the privacy of specific individuals in video recordings. We address the following two problems: automatic people identification with limited labeled data, and human body obscuring with preserved structure and motion information. In order to address the first problem, we propose a new discriminative learning algorithm to improve people identification accuracy using limited training data labeled from the original video and imperfect pairwise constraints labeled from face obscured video data. We employ a robust face detection and tracking algorithm to obscure human faces in the video. Our experiments in a nursing home environment show that the system can obtain a high accuracy of people identification using limited labeled data and noisy pairwise constraints. The study result indicates that human subjects can perform reasonably well in labeling pairwise constraints with the face masked data. For the second problem, we propose a novel method of body obscuring, which removes the appearance information of the people while preserving rich structure and motion information. The proposed approach provides a way to minimize the risk of exposing the identities of the protected people while maximizing the use of the captured data for activity/behavior analysis.
Still-to-video face recognition in unconstrained environments

Wang, Haoyu; Liu, Changsong; Ding, Xiaoqing
2015-02-01
Face images from video sequences captured in unconstrained environments usually contain several kinds of variations, e.g. pose, facial expression, illumination, image resolution and occlusion. Motion blur and compression artifacts also deteriorate recognition performance. Besides, in various practical systems such as law enforcement, video surveillance and e-passport identification, only a single still image per person is enrolled as the gallery set. Many existing methods may fail to work due to variations in face appearances and the limit of available gallery samples. In this paper, we propose a novel approach for still-to-video face recognition in unconstrained environments. By assuming that faces from still images and video frames share the same identity space, a regularized least squares regression method is utilized to tackle the multi-modality problem. Regularization terms based on heuristic assumptions are enrolled to avoid overfitting. In order to deal with the single image per person problem, we exploit face variations learned from training sets to synthesize virtual samples for gallery samples. We adopt a learning algorithm combining both affine/convex hull-based approach and regularizations to match image sets. Experimental results on a real-world dataset consisting of unconstrained video sequences demonstrate that our method outperforms the state-of-the-art methods impressively.

Background Based on the self-efficacy theory, an online and a face-to-face self-management programs ‘Challenge your Arthritis’ for young adults with a rheumatic disease have recently been developed. These two courses are led by young peer leaders. The objective of this study was to test the feasibility of the online and face-to-face self-management program. Methods Feasibility was evaluated on items of perceived usefulness, perceived ease of use, user-acceptance, and adherence to both programs in young adults and peer leaders. Additional analyses of interactions on the e-Health applications, discussion board and chat board, were conducted. Results Twenty-two young adults with a diagnosed rheumatic disease participated in the study: 12 young adults followed the online program and 10 followed the face-to-face program. Both programs appeared to be feasible, especially in dealing with problems in daily life, and the participants indicated the time investment as ‘worthwhile’. In using the online program, no technical problems occurred. Participants found the program easy to use, user friendly, and liked the ‘look and feel’ of the program. Conclusions Both the online and the face-to-face versions of a self-management program. ‘Challenge your arthritis’ were found to be feasible and well appreciated by young adults with a rheumatic disease. Because these programs are likely to be a practical aid to health practices, a randomized controlled study to investigate the effects on patient outcomes is planned. PMID:24666817

Soil erosion represents a geomorphological and geological hazard that may cause environmental damage (land degradation), property damage, loss of livelihoods and services as well as social and economic disruption. Erosion not only lowers the quality of our soils on site, resulting in a drastic reduction of their ecosystem functions that play a vital role in daily life, but causes also significant sediment-related problems off site. To curb soil erosion problems, a range of soil conservation techniques and strategies have been designed and are being applied. Worldwide, ca. 62 000 research papers on soil erosion and 116 000 on soil conservation have been published (Web of Science, Dec. 2015). The number of such papers dealing with the Global South represents less than 20 % of all papers, despite the fact that many regions in this part of the world face significant soil erosion problems, aggravated by a rapidly growing population and major environmental changes. Given the large number of research papers on this topic, one might therefore conclude that we now know almost everything about the various soil erosion processes and rates, their factors and consequences as well as their control so that little new knowledge can still be added to the vast amount of available information. We refute this conclusion by pointing to some major research gaps that still need to be addressed if we want to use our soils in a more sustainable way. More specifically the following topics need more research attention: 1) improved understanding of both natural and anthropogenic soil erosion processes and their interactions, 2) scaling up soil erosion processes and rates in space and time, and 3) innovative techniques and strategies to prevent or reduce erosion rates. This will be illustrated with case studies from the Global South. If future research focuses on these research gaps, we will 1) better understand processes and their interactions operating at a range of spatial and temporal scales, their rates as well as their on-site and off-site impacts, which is crucial for better targeting erosion control measures and which is academically spoken rewarding, and 2) we will also be in a better position to select the most appropriate and effective soil erosion control techniques and strategies which are badly needed for a sustainable use of our soils in the Anthropocene and for the improvement of environmental conditions worldwide.

Grapevines are produced worldwide with important impact on local economies. Several biotic stresses induce serious diseases of grapevine, which severely affect the quantity and quality of production. One of the most important problems of vineyards worldwide is the high incidence of grapevine trunk diseases (GTD) induced by fungi belonging to several genera. Environmentally friendly methods for GTD control are being studied. This perspective offers an advanced overview on the fungal phytotoxins involved in GTD and their eventual role in the development of disease symptoms.
The end of the (forensic science) world as we know it? The example of trace evidence
Roux, Claude; Talbot-Wright, Benjamin; Robertson, James; Crispino, Frank; Ribaux, Olivier
2015-01-01
The dominant conception of forensic science as a patchwork of disciplines primarily assisting the criminal justice system (i.e. forensics) is in crisis or at least shows a series of anomalies and serious limitations. In recent years, symptoms of the crisis have been discussed in a number of reports by various commentators, without a doubt epitomized by the 2009 report by the US National Academies of Sciences (NAS 2009 Strengthening forensic science in the United States: a path forward). Although needed, but viewed as the solution to these drawbacks, the almost generalized adoption of stricter business models in forensic science casework compounded with ever-increasing normative and compliance processes not only place additional pressures on a discipline that already appears in difficulty, but also induce more fragmentation of the different forensic science tasks, a tenet many times denounced by the same NAS report and other similar reviews. One may ask whether these issues are not simply the result of an unfit paradigm. If this is the case, the current problems faced by forensic science may indicate future significant changes for the discipline. To facilitate broader discussion this presentation focuses on trace evidence, an area that is seminal to forensic science both for epistemological and historical reasons. There is, however, little doubt that this area is currently under siege worldwide. Current and future challenges faced by trace evidence are discussed along with some possible answers. The current situation ultimately presents some significant opportunities to re-invent not only trace evidence but also forensic science. Ultimately, a distinctive, more robust and more reliable science may emerge through rethinking the forensics paradigm built on specialisms, revisiting fundamental forensic science principles and adapting them to the twenty-first century.

This study sought to describe how women in Mexico who have suffered from gender-based violence experience their encounters with healthcare professionals. Gender-based violence is a worldwide problem. Previous studies have described that women feel they are not being cared for appropriately during their encounters with healthcare professionals. This study was conducted in Mexico, which has a high rate of gender inequality. A descriptive, qualitative study was conducted. Face-to-face interviews were conducted with seven women. An inductive content analysis was used to analyse the interviews. The analyses resulted in four categories: Feelings of guilt about being abused, Feelings of being unimportant, Feelings of taking time and Feelings of being insecure/secure. The women emphasised the importance of healthcare professionals taking time out of their busy schedules for them. When they treated the women with respect and genuine interest, the women felt secure. When the healthcare professionals did not meet these expectations, feelings of frustration and mistrust were elicited. Feelings of being listened to and safety were considered important aspects in a positive encounter, whereas feeling a lack of time or interest often led to negative experiences such as frustration with and distrust of the healthcare system. These results imply that healthcare professionals may have deficiencies with regard to how these women are treated because these women do not feel that they receive the proper support. Education regarding how to approach women who have suffered from gender-based violence is essential for healthcare professionals to establish respectful encounters. The findings of this study stress that relatively simple efforts such as listening to these women's stories and providing them with genuine attention might substantially improve care. © 2017 John Wiley & Sons Ltd.
Agricultural Impacts on Water Resources: Recommendations for Successful Applied Research

Harmel, D.
2014-12-01
We, as water resource professionals, are faced with a truly monumental challenge - that is feeding the world's growing population and ensuring it has an adequate supply of clean water. As researchers and educators it is good for us to regularly remember that our research and outreach efforts are critical to people around the world, many of whom are desperate for solutions to water quality and supply problems and their impacts on food supply, land management, and ecosystem protection. In this presentation, recommendations for successful applied research on agricultural impacts on water resources will be provided. The benefits of building multidisciplinary teams will be illustrated with examples related to the development and world-wide application of the ALMANAC, SWAT, and EPIC/APEX models. The value of non-traditional partnerships will be shown by the Soil Health Partnership, a coalition of agricultural producers, chemical and seed companies, and environmental advocacy groups. The results of empowering decision-makers with useful data will be illustrated with examples related to bacteria source and transport data and the MANAGE database, which contains runoff nitrogen and phosphorus data for cultivated, pasture, and forest land uses. The benefits of focusing on sustainable solutions will be shown through examples of soil testing, fertilizers application, on-farm profit analysis, and soil health assessment. And the value of welcoming criticism will be illustrated by the development of a framework to estimate and publish uncertainty in measured discharge and water quality data. The good news for researchers is that the agricultural industry is faced with profitability concerns and the need to wisely utilize soil and water resources, and simultaneously state and federal agencies crave sound-science to improve decision making, policy, and regulation. Thus, the audience for and beneficiaries of agricultural research are ready and hungry for applied research results.

The aim of this study is to revisit the concept of malnutrition in older people, trace the new development and test the use of refined framework with empirical data. Malnutrition in older people is a common and significant problem worldwide. Continuing Chen's earlier work in 2001, a refinement was conducted and a prospective study was designed to test the use of this refined framework. A cohort study of 114 hospitalized older patients in Northern Taiwan. The sample consists of 114 older patients aged 65 years and older, who were admitted for the cardiac and orthopaedic services at a tertiary 2300-bed hospital. From March to August 2004, assessed by one trained nurse, participants completed a structured face-to-face interview evaluating their age, visual/hearing impairments, oral health, cognitive status, comorbidities, medication use, social economic status, functional status, social support, depressive symptoms and nutritional status within 48 hours of admission. Participants who stayed >5 days were reassessed before discharge (n = 70). The data from admission were the main focus of this report. Regression analysis revealed that that more medication taken, female gender, lower functional status (beta = 0.34, P < 0.001) and higher depressive symptoms were independent predictors of poor nutritional status, with the full model accounting for 48.2% of the variance. The result is in-line with the original theoretical underpinnings and it suggests that this refined framework detailing sub-concepts and measurable indices appears to fit the empirical data and suitable for clinical use. The findings lend support to the use of this framework in managing malnutrition in older people. Nurses have an essential role in providing care for older people a framework like this would provide a road map guiding the intervention efforts.

Preventable diet-related diseases such as dental caries and obesity are a growing global problem, causing a significant burden on public health systems. Although there has been good evidence for the links between sugar consumption and dental caries for many decades, we are now seeing stronger links implicating sugar in obesity. There is a growing worldwide movement to tackle these problems by targeting the consumption of sugar-sweetened beverages through a range of public policy measures.

Our aim was to identify the barriers young men face to consult a health professional when they encounter sexual dysfunctions and where they turn to, if so, for answers. We conducted an exploratory qualitative research including 12 young men aged 16-20 years old seen in two focus groups. Discussions were triggered through vignettes about sexual dysfunction. Young men preferred not to talk about sexual dysfunction problems with anyone and to solve them alone as it is considered an intimate and embarrassing subject which can negatively impact their masculinity. Confidentiality appeared to be the most important criterion in disclosing an intimate subject to a health professional. Participants raised the problem of males' accessibility to services and lack of reason to consult. Two criteria to address the problem were if it was long-lasting or considered as physical. The Internet was unanimously considered as an initial solution to solve a problem, which could guide them to a face-to-face consultation if necessary. Results suggest that Internet-based tools should be developed to become an easy access door to sexual health services for young men. Wherever they consult and for whatever problem, sexual health must be on the agenda.

Experiments on the Yale face database show that (i) selective Neural Network exhibits promising classification capability for face detection, recognition problems; and (ii) the proposed biometric-based module achieves near real-time face detection, recognition speed and the competitive performance, as compared to some existing subspaces-based methods.
Visual cryptography for face privacy

We discuss the problem of preserving the privacy of a digital face image stored in a central database. In the proposed scheme, a private face image is dithered into two host face images such that it can be revealed only when both host images are simultaneously available; at the same time, the individual host images do not reveal the identity of the original image. In order to accomplish this, we appeal to the field of Visual Cryptography. Experimental results confirm the following: (a) the possibility of hiding a private face image in two unrelated host face images; (b) the successful matching of face images that are reconstructed by superimposing the host images; and (c) the inability of the host images, known as sheets, to reveal the identity of the secret face image.
Orthogonal-blendshape-based editing system for facial motion capture data.
Li, Qing; Deng, Zhigang
2008-01-01
The authors present a novel data-driven 3D facial motion capture data editing system using automated construction of an orthogonal blendshape face model and constrained weight propagation, aiming to bridge the popular facial motion capture technique and blendshape approach. In this work, a 3D facial-motion-capture-editing problem is transformed to a blendshape-animation-editing problem. Given a collected facial motion capture data set, we construct a truncated PCA space spanned by the greatest retained eigenvectors and a corresponding blendshape face model for each anatomical region of the human face. As such, modifying blendshape weights (PCA coefficients) is equivalent to editing their corresponding motion capture sequence. In addition, a constrained weight propagation technique allows animators to balance automation and flexible controls.

In this paper, we have developed an algorithm to track the pose of a human face robustly and efficiently. Face pose estimation is very useful in many applications such as building virtual reality systems and creating an alternative input method for the disabled. Firstly, we have modified a face detection toolbox called DLib for the detection of a face in front of a camera. The detected face features are passed to a pose estimation method, known as the four-point algorithm, for pose computation. The theory applied and the technical problems encountered during system development are discussed in the paper. It is demonstrated that the system is able to track the pose of a face in real time using a consumer grade laptop computer.

2017-02-01
Some problems are difficult to solve by using a single intelligent information technology (IIT). The ensemble of the various data mining (DM) techniques is a set of models which are able to solve the problem by itself, but the combination of which allows increasing the efficiency of the system as a whole. Using the IIT ensembles can improve the reliability and efficiency of the final decision, since it emphasizes on the diversity of its components. The new method of the intellectual informational technology ensemble design is considered in this paper. It is based on the fuzzy logic and is designed to solve the classification and regression problems. The ensemble consists of several data mining algorithms: artificial neural network, support vector machine and decision trees. These algorithms and their ensemble have been tested by solving the face recognition problems. Principal components analysis (PCA) is used for feature selection.
“Live Chat” Clients at Kids Help Phone: Individual Characteristics and Problem Topics

2016-01-01
Objective Young people in Canada prefer to use the Internet over face-to-face contact when seeking help for problems of daily living and mental health problems. Kids Help Phone (KHP) provides on-demand, anonymous help to young people via telephone and Live Chat technologies. Methods Two hundred thirty-two phone clients and 230 Live Chat clients responded to a questionnaire at this otherwise anonymous service, providing previously inaccessible data about their individual characteristics and characterizations of the problems for which they sought help. Results There was a larger proportion of weighty problems (mental health and suicide) among chatters than callers. There were also more non-heterosexual youth, and those who identified as Asian and Black African or Caribbean, using Live Chat than phone. Conclusions Implications for training Live Chat counsellors to respond effectively to chatters are discussed. PMID:27924143

Science educators' perceptions of problems facing science education: A report of five surveys
NASA Astrophysics Data System (ADS)
Gallagher, James Joseph; Yager, Robert E.
Five groups of science educators representing faculty at graduate institutions, graduate students, teachers, supervisors, and leadership conferees were surveyed concerning their perceptions of current problems facing science education. A total of 144 participants provided an average of 4.7 responses. The responses were tabulated using an emergent set of categories that resulted in six major groupings, i.e. conceptual, organizational, teacher; related, student-related, university, and societal. The category with the most problems identified was in the area of conceptual problems. University related problems and organizational problems were the next two most frequently mentioned categories for problems. Specific problems in all categories most often cited include the following:1confusion and uncertainty in goals and objectives;2lack of vision and leadership in schools and universities;3absence of a theoretical base for science education;4poor quality teacher education programs;5inappropriate avenues for continuing education of teachers; limited dialogue between researchers and practitioners; declining enrollments; poor quality teaching and counseling; insufficient programs in science for the wide spectrum of students; and public and parental apathy towards science.
A multi-view face recognition system based on cascade face detector and improved Dlib
NASA Astrophysics Data System (ADS)
Zhou, Hongjun; Chen, Pei; Shen, Wei
2018-03-01
In this research, we present a framework for multi-view face detect and recognition system based on cascade face detector and improved Dlib. This method is aimed to solve the problems of low efficiency and low accuracy in multi-view face recognition, to build a multi-view face recognition system, and to discover a suitable monitoring scheme. For face detection, the cascade face detector is used to extracted the Haar-like feature from the training samples, and Haar-like feature is used to train a cascade classifier by combining Adaboost algorithm. Next, for face recognition, we proposed an improved distance model based on Dlib to improve the accuracy of multiview face recognition. Furthermore, we applied this proposed method into recognizing face images taken from different viewing directions, including horizontal view, overlooks view, and looking-up view, and researched a suitable monitoring scheme. This method works well for multi-view face recognition, and it is also simulated and tested, showing satisfactory experimental results.

To analyse preterm birth rates worldwide to assess the incidence of this public health problem, map the regional distribution of preterm births and gain insight into existing assessment strategies. Data on preterm birth rates worldwide were extracted during a previous systematic review of published and unpublished data on maternal mortality and morbidity reported between 1997 and 2002. Those data were supplemented through a complementary search covering the period 2003-2007. Region-specific multiple regression models were used to estimate the preterm birth rates for countries with no data. We estimated that in 2005, 12.9 million births, or 9.6% of all births worldwide, were preterm. Approximately 11 million (85%) of these preterm births were concentrated in Africa and Asia, while about 0.5 million occurred in each of Europe and North America (excluding Mexico) and 0.9 million in Latin America and the Caribbean. The highest rates of preterm birth were in Africa and North America (11.9% and 10.6% of all births, respectively), and the lowest were in Europe (6.2%). Preterm birth is an important perinatal health problem across the globe. Developing countries, especially those in Africa and southern Asia, incur the highest burden in terms of absolute numbers, although a high rate is also observed in North America. A better understanding of the causes of preterm birth and improved estimates of the incidence of preterm birth at the country level are needed to improve access to effective obstetric and neonatal care.

To evaluate the impact on the general public of England's Time to Change program to reduce mental health-related stigma and discrimination using newly developed measures of knowledge and intended behaviour regarding people with mental health problems, and an established attitudes scale, and to investigate whether social desirability affects responses to the new measures and test whether this varies according to data collection method. The Mental Health Knowledge Schedule (MAKS) and Reported and Intended Behaviour Scale (RIBS) were administered together with the 13-item version of the Marlowe-Crowne Social Desirability Scale to 2 samples (each n = 196) drawn from the Time to Change mass media campaign target group; one group was interviewed face to face, while the other completed the measures as an online survey. After controlling for other covariates, interaction terms between collection method and social desirability were positive for each instrument. The social desirability score was associated with the RIBS score in the face-to-face group only (β = 0.35, 95% CI 0.14 to 0.57), but not with the MAKS score in either group; however, MAKS scores were more likely to be positive when data were collected face to face (β = 1.53, 95% CI 0.74 to 2.32). Behavioural intentions toward people with mental health problems may be better assessed using online self-complete methods than in-person interviews. The effect of face-to-face interviewing on knowledge requires further investigation.

Workplace safety in Bangladesh ready-made garment sector: 3 years after the Rana Plaza collapse.
Barua, Uttama; Ansary, Mehedi Ahmed
2017-12-01
Workplace safety is one of the most important issues in industries worldwide, and is endangered by industrial accidents. Different industrial disasters have resulted in several initiatives worldwide to protect human life and reduce material damage, both nationally and internationally. In Bangladesh, the ready-made garment (RMG) industry is one of the most important export-oriented business sectors, which is facing challenges to ensure workplace safety. The Rana Plaza collapse in Bangladesh is the consequence of such non-compliance. The accident resulted in different local and global initiatives to address the challenges. This article reviews progress and achievement of the initiatives to reduce vulnerability in the Bangladesh RMG industry within 3 years after the deadly accident. In the long run, the challenge is to maintain momentum already created for achieving sustainability in the RMG sector in Bangladesh and maintaining compliance even after the end of support from external partners.

Family caregivers of persons with advanced cancer often take on responsibilities that present daunting and complex problems. Serious problems that go unresolved may be burdensome and result in negative outcomes for caregivers’ psychological and physical health and affect the quality of care delivered to the care recipients with cancer, especially at the end of life. Formal problem-solving training approaches have been developed over the past several decades to assist individuals with managing problems faced in daily life. Several of these problem-solving principles and techniques were incorporated into ENABLE (Educate, Nurture, Advise, Before Life End), an ‘early’ palliative care telehealth intervention for individuals diagnosed with advanced cancer and their family caregivers. A hypothetical case resembling the situations of actual caregiver participants in ENABLE that exemplifies the complex problems that caregivers face is presented followed by presentation of an overview of ENABLE’s problem-solving key principles, techniques and steps in problem-solving support. Though more research is needed to formally test the use of problem-solving support in social work practice, social workers can easily incorporate these techniques into everyday practice.

Blended therapy describes the use of computerised therapy combined with face-to-face therapy to extend the depth, range and nature of the face-to-face therapy. We wanted to develop a treatment manual for a randomised trial of blended therapy combining face-to-face problem solving and a smartphone app in men who present to hospital with self-harm. To develop a treatment manual and to describe the experience of receiving and delivering a blended therapy. After completion of the blended therapy, semistructured qualitative interviews were conducted with participants to describe their experience of the treatment. Two independent coders analysed the material using a thematic, grounded theory approach. Seven men were enrolled in the study, and six completed the qualitative interviews. The two main themes identified were of trust and connection. Participants attended 85% of their appointments. In the treatment manual, we emphasised the themes of trust and connection by allowing time to discuss the app in the face-to-face to sessions, ensuring that therapists are familiar with the app and know how to respond to technical queries. Identification of trust and connection generates novel questions about the importance of the therapeutic alliance with technology rather than with people. Clinicians and app developers need to pay attention to the therapeutic relationship with technology as trust and good communication can be easily damaged, resulting in disengagement with the app. Blended therapy may result in increased adherence to face-to-face sessions.

A hierarchy of stability exists among the types of surgical movements that are possible with orthognathic surgery. This report updates the hierarchy, focusing on comparison of the stability of procedures when rigid fixation is used. Two procedures not previously placed in the hierarchy now are included: correction of asymmetry is stable with rigid fixation and repositioning of the chin also is very stable. During the first post-surgical year, surgical movements in patients treated for Class II/long face problems tend to be more stable than those treated for Class III problems. Clinically relevant changes (more than 2 mm) occur in a surprisingly large percentage of orthognathic surgery patients from one to five years post-treatment, after surgical healing is complete. During the first post-surgical year, patients treated for Class II/long face problems are more stable than those treated for Class III problems; from one to five years post-treatment, some patients in both groups experience skeletal change, but the Class III patients then are more stable than the Class II/long face patients. Fewer patients exhibit long-term changes in the dental occlusion than skeletal changes, because the dentition usually adapts to the skeletal change.

Managing Problems Before Problems Manage You, presents 12 different concepts for managing problems, not "cookie cutter" solutions, but different ideas that you can apply as they fit your circumstances.
Empathy and face processing in adults with and without autism spectrum disorder.
Rigby, Sarah N; Stoesz, Brenda M; Jakobson, Lorna S
2018-06-01
Many factors contribute to social difficulties in individuals with autism spectrum disorder (ASD). The goal of the present work was to determine whether atypicalities in how individuals with ASD process static, socially engaging faces persist when nonrigid facial motion cues are present. We also sought to explore the relationships between various face processing abilities and individual differences in autism symptom severity and traits such as empathy. Participants included 16 adults with ASD without intellectual impairment and 16 sex- and age-matched controls. Mean Verbal IQ was comparable across groups [t(30) = 0.70, P = 0.49]. The two groups responded similarly to many of the experimental manipulations; however, relative to controls, participants with ASD responded more slowly to dynamic expressive faces, even when no judgment was required; were less accurate at identity matching with static and dynamic faces; and needed more time to make identity and expression judgments [F(1, 30) ≥ 6.37, P ≤ 0.017, η p 2 ≥ 0.175 in all cases], particularly when the faces were moving [F(1, 30) = 3.40, P = 0.072, η p 2 = 0.104]. In the full sample, as social autistic traits increased and empathic skills declined, participants needed more time to judge static identity, and static or dynamic expressions [0.43 < |r s | < 0.56]. The results suggest that adults with ASD show general impairments in face and motion processing and support the view that an examination of individual variation in particular personality traits and abilities is important for advancing our understanding of face perception. Autism Res 2018, 11: 942-955. © 2018 International Society for Autism Research, Wiley Periodicals, Inc. Our findings suggest that people with ASD have problems processing expressive faces, especially when seen in motion. It is important to learn who is most at risk for face processing problems, given that in the general population such problems appear to be linked to impaired social skills and empathy. By studying relationships between different abilities and traits, we may be able to find better ways to diagnose and support all people on the autism spectrum. © 2018 International Society for Autism Research, Wiley Periodicals, Inc.

In the post Cold War era, the East-West conflict may be succeeded by a new confrontation which pits an industrialized North against a developing South. In June 1992, world attention was fixed on the Earth Summit in Rio de Janeiro. This event marked a milestone in global environmental awareness; but just as the end of the Cold War has provided new opportunities for the US, the world is now faced with new sources of conflict which have advanced to the forefront of the national security debate. Among the new sources of conflict, environmental problems are rapidly becoming preeminent. Within nationalmore » security debates, those environmental problems which respect no international boundary are of particular concern. Worldwide deforestation, and the related issues of global warming and the loss of biodiversity, represent a clear threat to national security. Two percent of the Earth's rainforests are lost each year; one 'football field' is lost each second. Deforestation has already led to conflict and instability within several regions of the world including Southeast Asia. The United States must recognize the character and dynamics of these new sources of conflict in order to successfully realize its policy aims in national security. The US should preempt conflict through cooperation and develop a shared concern for the environment throughout the world. The US military may play a key role in this effort.

Humanity must face enormous environmental challenges including biodiversity decline, climate change, ocean acidification, sea level rise and overpopulation. The research infrastructures (RIs) created in the last decades worldwide cover a wide range of spatial and thematic scales and collect information about the functioning of Earth ecosystems. However, we need to go one step forward: understand and simulate the functioning of the Earth as a complex system in a global change scenario. Cooperation among international RIs as well as multidisciplinary work are mandatory to achieve this challenging objective. COOP+ (EU Horizon 2020 project) aims to strengthen the links and coordination of European environmental RIs with their international counterparts. COOP+ will create cooperation threads among international research infrastructures using environmental Global Challenges (GCs) as thematic guidelines. These GCs are polyhedral and sometimes wicked problems that threaten the sustainability of our modern societies from a social and environmental perspective. This contribution describes how COOP+ uses GCs as guidelines to foster cooperation among RIs. First we have created an open survey to collect ideas about GCs within the different scientific communities. We present the structure of this survey as well as the preliminary information that it contains. The survey will be accepting responses during the project life (September 2018). We also describe the structure of a template that will be used to collaboratively characterize some selected GCs under the point of view of RIs. The main idea is to assess how RIs can be useful to address global environmental problems. We encourage all scientists related to RIs communities to participate in this process.

Emotion recognition problems are frequently reported in individuals with an autism spectrum disorder (ASD). However, this research area is characterized by inconsistent findings, with atypical emotion processing strategies possibly contributing to existing contradictions. In addition, an attenuated saliency of the eyes region is often demonstrated in ASD during face identity processing. We wanted to compare reliance on mouth versus eyes information in children with and without ASD, using hybrid facial expressions. A group of six-to-eight-year-old boys with ASD and an age- and intelligence-matched typically developing (TD) group without intellectual disability performed an emotion labelling task with hybrid facial expressions. Five static expressions were used: one neutral expression and four emotional expressions, namely, anger, fear, happiness, and sadness. Hybrid faces were created, consisting of an emotional face half (upper or lower face region) with the other face half showing a neutral expression. Results showed no emotion recognition problem in ASD. Moreover, we provided evidence for the existence of top- and bottom-emotions in children: correct identification of expressions mainly depends on information in the eyes (so-called top-emotions: happiness) or in the mouth region (so-called bottom-emotions: sadness, anger, and fear). No stronger reliance on mouth information was found in children with ASD.

Objective To assess pharmacy students' attitudes towards a blended-learning pharmacokinetics course. Design Narrated visual presentations and animations that illustrated kinetic processes and guided students through the use of software programs used for calculations were created. Other learning techniques used included online self-assessment quizzes, practice problem sets, and weekly face-to-face problem-solving tutorials. Assessment A precourse questionnaire to assess students' level of enthusiasm towards the blended-learning course and to solicit any concerns they had was administered at the beginning of the course. A postcourse questionnaire that included the same 4 Likert-scale items from the precourse questionnaire and follow-up open-ended questions was administered. Individual changes in level of enthusiasm were compared for individuals who completed both the precourse and postcourse questionnaire. Students' concerns about the blended method of learning had decreased postcourse while their enthusiasm for the benefits of blended learning had increased. Conclusion Students' initial concerns about the blended learning experience were focused on their ability to communicate with the instructor about the online components, but shifted to their own time management skills at the end of the course. Face-to-face interactions with each other and with the instructor were more highly rated than online interactions in this course. PMID:20798797

Non-melanoma skin cancers (NMSCs) are the most common malignancy worldwide, of which 99% are basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) of skin. NMSCs are generally considered a curable diseases, yet they currently pose an increasing global healthcare problem due to rising incidence. This has led to a shift in emphasis on prevention of NMSCs with development of various skin cancer prevention programs worldwide. This article aims to summarize the most recent changes and advances made in NMSC management with a focus on prevention, screening, diagnosis, and staging. PMID:29104226

Blending online modules into face-to-face therapy offers perspectives to enhance patient self-management and to increase the (cost-)effectiveness of therapy, while still providing the support patients need. The aim of this study was to outline optimal usage of blended care for depression, according to patients and therapists. A Delphi method was used to find consensus on suitable blended protocols (content, sequence and ratio). Phase 1 was an explorative phase, conducted in two rounds of online questionnaires, in which patients' and therapists' preferences and opinions about online psychotherapy were surveyed. In phase 2, data from phase 1 was used in face-to-face interviews with therapists to investigate how blended therapy protocols could be set up and what essential preconditions would be. Twelve therapists and nine patients completed the surveys. Blended therapy was positively perceived among all respondents, especially to enhance the self-management of patients. According to most respondents, practical therapy components (assignments, diaries and psycho-education) may be provided via online modules, while process-related components (introduction, evaluation and discussing thoughts and feelings), should be supported face-to-face. The preferred blend of online and face-to-face sessions differs between therapists and patients; most therapists prefer 75% face-to-face sessions, most patients 50 to 60%. The interviews showed that tailoring treatment to individual patients is essential in secondary mental health care, due to the complexity of their problems. The amount and ratio of online modules needs to be adjusted according to the patient's problems, skills and characteristics. Therapists themselves should also develop skills to integrate online and face-to-face sessions. Blending online and face-to-face sessions in an integrated depression therapy is viewed as a positive innovation by patients and therapists. Following a standard blended protocol, however, would be difficult in secondary mental health care. A database of online modules could provide flexibility to tailor treatment to individual patients, which asks motivation and skills of both patients and therapists. Further research is necessary to determine the (cost-)effectiveness of blended care, but this study provides starting points and preconditions to blend online and face-to-face sessions and create a treatment combining the best of both worlds.

Major depressive disorder (MDD) is a leading cause of disability worldwide and occurs commonly first during adolescence. The insular cortex (IC) plays an important role in integrating emotion processing with interoception and has been implicated recently in the pathophysiology of adult and adolescent MDD. However, no studies have yet specifically examined the IC in adolescent MDD during processing of faces in the sad-happy continuum. Thus, the aim of the present study is to investigate the IC during sad and happy face processing in adolescents with MDD compared to healthy controls (HCL). Thirty-one adolescents (22 female) with MDD and 36 (23 female) HCL underwent a well-validated emotional processing fMRI paradigm that included sad and happy face stimuli. The MDD group showed significantly less differential activation of the anterior/middle insular cortex (AMIC) in response to sad versus happy faces compared to the HCL group. AMIC also showed greater functional connectivity with right fusiform gyrus, left middle frontal gyrus, and right amygdala/parahippocampal gyrus in the MDD compared to HCL group. Moreover, differential activation to sad and happy faces in AMIC correlated negatively with depression severity within the MDD group. Small age-range and cross-sectional nature precluded assessment of development of the AMIC in adolescent depression. Given the role of the IC in integrating bodily stimuli with conscious cognitive and emotional processes, our findings of aberrant AMIC function in adolescent MDD provide a neuroscientific rationale for targeting the AMIC in the development of new treatment modalities.

Background: Access to a quiet side in one’s dwelling is thought to compensate for higher noise levels at the most exposed façade. It has also been indicated that noise from combined traffic sources causes more noise annoyance than equal average levels from either road traffic or railway noise separately. Methods: 2612 persons in Malmö, Sweden, answered to a residential environment survey including questions on outdoor environment, noise sensitivity, noise annoyance, sleep quality and concentration problems. Road traffic and railway noise was modeled using Geographic Information System. Results: Access to a quiet side, i.e., at least one window facing yard, water or green space, was associated with reduced risk of annoyance OR (95%CI) 0.47 (0.38–0.59), and concentration problems 0.76 (0.61–0.95). Bedroom window facing the same environment was associated to reduced risk of reporting of poor sleep quality 0.78 (0.64–1.00). Railway noise was associated with reduced risk of annoyance below 55 dB(A) but not at higher levels of exposure. Conclusions: Having a window facing a yard, water or green space was associated to a substantially reduced risk of noise annoyance and concentration problems. If this window was the bedroom window, sleeping problems were less likely. PMID:25642690

BACKGROUND Medication-related problems occur at high rates during care transitions. Evidence suggests that pharmacists are well-suited to identify and resolve medication-related problems during hospital admission and at discharge. Additional evidence is needed to understand the impact of face-to-face pharmacist visits in primary care after discharge. The purpose of the study was to describe medication-related problems found during face-to-face pharmacist visits in a medical home after hospital discharge. METHODS A retrospective cohort study was conducted within an academic primary care center staffed by family medicine trained physicians that evaluated patients who attended a hospital follow-up visit with pharmacist-enhanced care (N = 86) versus usual care (N = 86). The primary objective was to describe medication-related problems identified by pharmacists using a modified individualized Medication Assessment and Planning tool for patients receiving pharmacist-enhanced care. Secondary analyses were also conducted to compare 30-day and 60-day hospital readmission and emergency department visit rates in those exposed to pharmacist-enhanced care versus those who were not. RESULTS At baseline, the mean hospitalizations in the prior year were 1.1 ± 1.7 (pharmacist-enhanced care) and 0.76 ± 1.2 (usual care), indicating a low initial readmission risk. Of patients receiving pharmacist-enhanced care, 97.7% were found to have at least 1 medication-related problem, with an average of 4.36 medication-related problems per patient. The 30-day readmission rate was lower, but not significantly different between groups (8.1% for pharmacist-enhanced care versus 12.8% for usual care; adjusted odds ratio (OR), 0.47; 95% confidence interval (CI), 0.16-1.36). LIMITATIONS Limitations include the retrospective cohort study design and small sample size. Medication-related problems were identified and collected prospectively during pharmacist visits. CONCLUSION Medication-related problems are ubiquitous after hospital discharge. Larger prospective studies will be needed to understand the potential value of pharmacist-enhanced care during hospital follow-up visits on readmission rates in low-risk patient populations receiving care within a primary care medical home. ©2018 by the North Carolina Institute of Medicine and The Duke Endowment.

Problem gambling worldwide: An update and systematic review of empirical research (2000–2015)
Calado, Filipa; Griffiths, Mark D.
2016-01-01
Background and aims Problem gambling has been identified as an emergent public health issue, and there is a need to identify gambling trends and to regularly update worldwide gambling prevalence rates. This paper aims to review recent research on adult gambling and problem gambling (since 2000) and then, in the context of a growing liberalization of the gambling market in the European Union, intends to provide a more detailed analysis of adult gambling behavior across European countries. Methods A systematic literature search was carried out using academic databases, Internet, and governmental websites. Results Following this search and utilizing exclusion criteria, 69 studies on adult gambling prevalence were identified. These studies demonstrated that there are wide variations in past-year problem gambling rates across different countries in the world (0.12–5.8%) and in Europe (0.12–3.4%). However, it is difficult to directly compare studies due to different methodological procedures, instruments, cut-offs, and time frames. Despite the variability among instruments, some consistent results with regard to demographics were found. Discussion and conclusion The findings highlight the need for continuous monitoring of problem gambling prevalence rates in order to examine the influence of cultural context on gambling patterns, assess the effectiveness of policies on gambling-related harms, and establish priorities for future research.

Tuberculosis--triumph and tragedy.
Singh, M M
2003-03-01
Tuberculosis has been making havoc worldwide with an 11.9 million cases to be involved by the year 2005. In India, about 2 million cases are infected every year. Regarding triumphs and tragedies in the control of tuberculosis some points as follows are discussed. (1) Tuberculosis Control Programmes from National Tuberculosis Programme (NTP) to Revised National Tuberculosis Control Programme (RNTCP) and Directly Observed Treatment, Short course (DOTS). (2) Problem of multidrug resistance (MDR) tuberculosis and (3) HIV and tuberculosis. DOTS being largely based on Indian research. It is now being applied worldwide. MDR is strictly a man made problem. Poor prescriptions, poor case management, lack of coordinated education and haphazard treatment research result in drug resistance. Treatment of MDR is difficult. The drug acceptability, tolerance and toxicity have to be considered. HIV and tuberculosis form a deadly duo. They mean more cases, more costs and more national losses.
New approaches in oral rotavirus vaccines.
Kuate Defo, Zenas; Lee, Byong
2016-05-01
Rotavirus is the leading cause of severe dehydrating diarrhea worldwide, and affects primarily developing nations, in large part because of the inaccessibility of vaccines and high rates of mortality present therein. At present, there exist two oral rotaviral vaccines, Rotarix™ and RotaTeq™. These vaccines are generally effective in their actions: however, associated costs often stymie their effectiveness, and they continue to be associated with a slight risk of intussusception. While different programs are being implemented worldwide to enhance vaccine distribution and monitor vaccine administration for possible intussusception in light of recent WHO recommendation, another major problem persists: that of the reduced efficacy of the existing rotaviral vaccines in developing countries over time. The development of new oral rotavirus vaccine classes - live-attenuated vaccines, virus-like particles, lactic acid bacteria-containing vaccines, combination therapy with immunoglobulins, and biodegradable polymer-encapsulated vaccines - could potentially circumvent these problems.

Public-private partnerships have become a common approach to health care problems worldwide. Many public-private partnerships were created during the late 1990s, but most were focused on specific diseases such as HIV/AIDS, tuberculosis, and malaria. Recently there has been enthusiasm for using public-private partnerships to improve the delivery of health and welfare services for a wider range of health problems, especially in developing countries. The success of public-private partnerships in this context appears to be mixed, and few data are available to evaluate their effectiveness. This analysis provides an overview of the history of health-related public-private partnerships during the past 20 years and describes a research protocol commissioned by the World Health Organization to evaluate the effectiveness of public-private partnerships in a research context.

Education is a fundamental component for patients with diabetes to achieve good glycemic control. In addition, selecting the appropriate method of education is one of the most effective factors in the quality of life. The present study aimed to evaluate the effect of face-to-face education, problem-based learning, and Goldstein systematic training model on the quality of life (QOL) and fatigue among caregivers of patients with diabetes. This randomized clinical trial was conducted in Hajar Hospital (Shahrekord, Iran) in 2012. The study subjects consisted of 105 family caregivers of patients with diabetes. The participants were randomly assigned to three intervention groups (35 caregivers in each group). For each group, 5-h training sessions were held separately. QOL and fatigue were evaluated immediately before and after the intervention, and after 1, 2, 3, and 4 months of intervention. There was a significant increase in QOL for all the three groups. Both the problem-based learning and the Goldstein method showed desirable QOL improvement over time. The desired educational intervention for fatigue reduction during the 4-month post-intervention period was the Goldstein method. A significant reduction was observed in fatigue in all three groups after the intervention ( P < 0.001). The results of the present study illustrated that the problem-based learning and Goldstein systematic training model improve the QOL of caregivers of patients with diabetes. In addition, the Goldstein systematic training model had the greatest effect on the reduction of fatigue within 4 months of the intervention.

Multi-camera networks have gained great interest in video-based surveillance systems for security monitoring, access control, etc. Person re-identification is an essential and challenging task in multi-camera networks, which aims to determine if a given individual has already appeared over the camera network. Individual recognition often uses faces as a trial and requires a large number of samples during the training phrase. This is difficult to fulfill due to the limitation of the camera hardware system and the unconstrained image capturing conditions. Conventional face recognition algorithms often encounter the "small sample size" (SSS) problem arising from the small number of training samples compared to the high dimensionality of the sample space. To overcome this problem, interest in the combination of multiple base classifiers has sparked research efforts in ensemble methods. However, existing ensemble methods still open two questions: (1) how to define diverse base classifiers from the small data; (2) how to avoid the diversity/accuracy dilemma occurring during ensemble. To address these problems, this paper proposes a novel generic learning-based ensemble framework, which augments the small data by generating new samples based on a generic distribution and introduces a tailored 0-1 knapsack algorithm to alleviate the diversity/accuracy dilemma. More diverse base classifiers can be generated from the expanded face space, and more appropriate base classifiers are selected for ensemble. Extensive experimental results on four benchmarks demonstrate the higher ability of our system to cope with the SSS problem compared to the state-of-the-art system.

Though the impact of social inequality on health conditions is widely known, its impact on the chronic and stigmatized disease, leprosy, has received little attention. Deformity sometimes leads to disabilities and to handicaps causing problems to the patient and his family. In this paper an attempt has been made to understand the impact of social inequality, prevalent in the form of the caste system in India on the deformed leprosy patients and on their families. This impact was examined in terms of the problems faced by the patients. A sample of 150 deformed patients and their families, drawn from two districts in Tamil Nadu, was selected for the study. About 57% of the deformed patients experienced their deformity as a handicap which caused social and economic problems while the rest did not. Of the three caste groups, the Lower Caste group experienced more severe economic problems while the Upper Caste group faced more social problems. The extent of acceptance of deformed patients in their family varied significantly among those facing and not facing problems due to their deformity. The deformed patients without any handicap were accepted in a large majority of their families (82%) regardless of their caste status. In contrast the deformed but handicapped patients were accepted differentially among the three caste groups with the Upper group accepting them in most of their families (80%) while in the Lower group much less number of families (54%) did. All the families of the deformed but not handicapped patients desired to keep their patients till their death irrespective of their caste status. On the contrary, while all the families in the Upper Caste group expressed their willingness to keep their handicapped patients in the family till their death, 10% in the Middle and 22% in the Lower Caste groups did not want to do so. This suggests the gradual marginalization, rejection and dehabilitation of the affected. Thus, one's caste status can be a broad indicator of the nature and the extent of handicaps and acceptance in the family. This factor needs to be appropriately taken care of for rehabilitation and disability management in leprosy control programmes.

A Method of Face Detection with Bayesian Probability
NASA Astrophysics Data System (ADS)
Sarker, Goutam
2010-10-01
The objective of face detection is to identify all images which contain a face, irrespective of its orientation, illumination conditions etc. This is a hard problem, because the faces are highly variable in size, shape lighting conditions etc. Many methods have been designed and developed to detect faces in a single image. The present paper is based on one `Appearance Based Method' which relies on learning the facial and non facial features from image examples. This in its turn is based on statistical analysis of examples and counter examples of facial images and employs Bayesian Conditional Classification Rule to detect the probability of belongingness of a face (or non-face) within an image frame. The detection rate of the present system is very high and thereby the number of false positive and false negative detection is substantially low.
How Alexander von Humboldt's life story can inspire innovative soil research in developing countries
NASA Astrophysics Data System (ADS)
Bouma, Johan
2017-09-01
The pioneering vision of Alexander von Humboldt of science and society of the early 1800s is still highly relevant today. His open mind and urge to make many measurements characterizing the interconnected web of life
are crucial ingredients as we now face the worldwide challenge of the UN Sustainable Development Goals. Case studies in the Philippines, Vietnam, Kenya, Niger, and Costa Rica demonstrate, in Alexander's spirit, interaction with stakeholders and attention to unique local conditions, applying modern measurement and modeling methods and allowing inter- and transdisciplinary research approaches. But relations between science and society are increasingly problematic, partly as a result of the information revolution and post-truth
, fact-free
thinking. Overly regulated and financially restricted scientific communities in so-called developed countries may stifle intellectual creativity. Researchers in developing countries are urged to leapfrog
these problems in the spirit of Alexander von Humboldt as they further develop their scientific communities. Six suggestions to the science community are made with particular attention to soil science. (The Humboldt lecture, presented by the 2017 recipient of the Alexander von Humboldt lecture, Johan Bouma, can be accessed at http://client.cntv.at/egu2017/ml1.)
Watershed Sediment Losses to Lakes Accelerating Despite Agricultural Soil Conservation Efforts
Heathcote, Adam J.; Filstrup, Christopher T.; Downing, John A.
2013-01-01
Agricultural soil loss and deposition in aquatic ecosystems is a problem that impairs water quality worldwide and is costly to agriculture and food supplies. In the US, for example, billions of dollars have subsidized soil and water conservation practices in agricultural landscapes over the past decades. We used paleolimnological methods to reconstruct trends in sedimentation related to human-induced landscape change in 32 lakes in the intensively agricultural region of the Midwestern United States. Despite erosion control efforts, we found accelerating increases in sediment deposition from erosion; median erosion loss since 1800 has been 15.4 tons ha−1. Sediment deposition from erosion increased >6-fold, from 149 g m−2 yr−1 in 1850 to 986 g m−2 yr−1 by 2010. Average time to accumulate one mm of sediment decreased from 631 days before European settlement (ca. 1850) to 59 days mm−1 at present. Most of this sediment was deposited in the last 50 years and is related to agricultural intensification rather than land clearance or predominance of agricultural lands. In the face of these intensive agricultural practices, traditional soil conservation programs have not decelerated downstream losses. Despite large erosion control subsidies, erosion and declining water quality continue, thus new approaches are needed to mitigate erosion and water degradation. PMID:23326454
