Moffat, A.S.

1998-02-13

This article discusses a global problem due to man`s intervention in the biosphere resulting from an increased production and usage of products producing nitrogen compounds which can be fixed in ecosystems. This problem was recognized on small scales even in the 1960`s, but recent studies on a more global scale show that the amount of nitrogen compounds in river runoff is strongly related to the use of synthetic fertilizers, fossil-fuel power plants, and automobile emissions. The increased fixed nitrogen load is exceeding the ability of some ecosystems to use or break the compounds down, resulting in a change in themore » types of flora and fauna which are found to inhabit the ecosystems, and leading to decreased biodiversity.« less

Qualitative methods: beyond the cookbook.

PubMed

Harding, G; Gantley, M

1998-02-01

Qualitative methods appear increasingly in vogue in health services research (HSR). Such research, however, has utilized, often uncritically, a 'cookbook' of methods for data collection, and common-sense principles for data analysis. This paper argues that qualitative HSR benefits from recognizing and drawing upon theoretical principles underlying qualitative data collection and analysis. A distinction is drawn between problem-orientated and theory-orientated research, in order to illustrate how problem-orientated research would benefit from the introduction of theoretical perspectives in order to develop the knowledge base of health services research.

Co-occurring problems of early onset persistent, childhood limited, and adolescent onset conduct problem youth.

PubMed

Barker, Edward D; Oliver, Bonamy R; Maughan, Barbara

2010-11-01

It is increasingly recognized that youth who follow early onset persistent (EOP), childhood limited (CL) and adolescent onset (AO) trajectories of conduct problems show somewhat varying patterns of risk (in childhood) and adjustment problems (in adolescence and adulthood). Little, however, is known about how other adjustment problems differentially co-develop with the EOP, CL and AO trajectories across the childhood and adolescent years. Using data from the Avon Longitudinal Study of Parents and Children, an epidemiological, longitudinal cohort of boys and girls, we estimated growth curves for parent-reported hyperactivity, emotional difficulties, peer relational problems, and prosocial behaviors conditional on trajectories of conduct problems (i.e., EOP, CL and AO) from ages 4 to 13 years. At ages 7-8 years, DSM-IV-based diagnoses of conduct disorder, oppositional-defiant disorder, attention deficit/hyperactivity disorder (ADHD), anxiety, depression were examined by conduct problems trajectory. Overall, the development of hyperactivity, emotional difficulties, peer relational problems, and prosocial behaviors mirrored the development of conduct problems, showing similar trajectories. Results indicated that the problems of EOP youth were persistent across domains, CL youth showed decreased behavior problems while increasing in prosocial behaviors, and AO youth increased in adjustment problems after 10 years of age. © 2010 The Authors.

Recognizing problem video game use.

PubMed

Porter, Guy; Starcevic, Vladan; Berle, David; Fenech, Pauline

2010-02-01

It has been increasingly recognized that some people develop problem video game use, defined here as excessive use of video games resulting in various negative psychosocial and/or physical consequences. The main objectives of the present study were to identify individuals with problem video game use and compare them with those without problem video game use on several variables. An international, anonymous online survey was conducted, using a questionnaire with provisional criteria for problem video game use, which the authors have developed. These criteria reflect the crucial features of problem video game use: preoccupation with and loss of control over playing video games and multiple adverse consequences of this activity. A total of 1945 survey participants completed the survey. Respondents who were identified as problem video game users (n = 156, 8.0%) differed significantly from others (n = 1789) on variables that provided independent, preliminary validation of the provisional criteria for problem video game use. They played longer than planned and with greater frequency, and more often played even though they did not want to and despite believing that they should not do it. Problem video game users were more likely to play certain online role-playing games, found it easier to meet people online, had fewer friends in real life, and more often reported excessive caffeine consumption. People with problem video game use can be identified by means of a questionnaire and on the basis of the present provisional criteria, which require further validation. These findings have implications for recognition of problem video game users among individuals, especially adolescents, who present to mental health services. Mental health professionals need to acknowledge the public health significance of the multiple negative consequences of problem video game use.

Height has long been recognized as being associated with better outcomes: the question is whether this association is causal. We use children's genetic variants as instrumental variables to deal with possible unobserved confounders and examine the effect of child/adolescent height on a wide range of outcomes: academic performance, IQ, self-esteem, depression symptoms and behavioral problems. OLS findings show that taller children have higher IQ, perform better in school, and are less likely to have behavioral problems. The IV results differ: taller girls (but not boys) have better cognitive performance and, in contrast to the OLS, greater height appears to increase behavioral problems. PMID:25673883

2015-01-01

Working with multiple contractors in a shared workplace can introduce and increase safety risks due to complexity. The aim of this study was to explore how safety issues are recognized in a specific case and to identify whether clients and contractors perceive problems similarly. The safety issues are explored through a brief survey and a workshop in the maintenance department of a logistics company. The results indicate that culture and behavior are recognized differently by clients and by contractors. The contractors and client had different perceptions of involvement of contractors by the client. The contractors complained on lack of involvement, which was not fully recognized by the client. The case study used a practical approach to show differences in perception of safety within a project. The study illustrates the need for more applied studies and interventions on contractor safety.

Workload and awkward posture problems among small-scale strawberry farmers in Japan.

Kumudini, Ganga; Hasegawa, Tetsuya

2009-12-01

Farmers handle heavy workloads, often in awkward postures and experiencing some work related problems. Farmers perceive them as no more than inevitable consequences of farming activities. Although many problems can be prevented or reduced by simple and inexpensive modifications to work, these problems are increasing among farmers. The main focus of the paper was to investigate workload and awkward postures among strawberry farmers and suggest possible solutions to overcome the identified problems. Questionnaires, direct observations and intertwining methods were used to collect the data. Low-level strawberry beds and long working hours were recognized as critical factors that led to farmers' health problems including suffering from low back pain, heavy fatigue, unsteady feeling after work, etc. There was a substantial increase in fatigue in busy seasons compared with slack seasons. When compared with the other workers such as office, technical, sales and blue-collar workers, female farmers' general fatigue level was considerably high. Findings indicated that strawberry farming was a stressful occupation and farmers were strained under heavy workload, monotonous and repetitive work and poor working conditions with frequent fatigue symptoms and severe influence on health.

Adults living with congenital heart disease (CHD) now outnumber children with the disease. Thanks to medical advances over the past 75 years, many of these fatal childhood heart problems have changed to chronic medical conditions. As the population of adults with CHD increases, they will require increasingly complex medical, surgical and catheter-based therapies. In addition, social burdens including education, employment and insurability, which increase the societal costs of adult CHD, are now being recognized for adults living with CHD. This review summarizes the available literature on the economics of adult CHD.

Hippocampal-neocortical functional reorganization underlies children's cognitive development

PubMed Central

Qin, Shaozheng; Cho, Soohyun; Chen, Tianwen; Rosenberg-Lee, Miriam; Geary, David C.; Menon, Vinod

2014-01-01

The importance of the hippocampal system for rapid learning and memory is well recognized, but its contributions to a cardinal feature of children's cognitive development – the transition from procedure-based to memory-based problem solving strategies – are unknown. Here we show that the hippocampal system is pivotal to this strategic transition. Longitudinal fMRI in children, ages 7 to 9, revealed that the transition from use of counting to memory-based retrieval parallels increased hippocampal and decreased prefrontal-parietal engagement during arithmetic problem solving. Critically, longitudinal improvements in retrieval strategy use were predicted by increased hippocampal-neocortical functional connectivity. Beyond childhood, retrieval strategy use continued to improve through adolescence into adulthood, and was associated with decreased activation but more stable inter-problem representations in the hippocampus. Our findings provide novel insights into the dynamic role of the hippocampus in the maturation of memory-based problem solving, and establish a critical link between hippocampal-neocortical reorganization and children's cognitive development.

Before twentieth centuries and during early twentieth centuries, communicable diseases were the major cause of morbidity and mortality in Korea. But reliable data are not available. After 1975, the overall morbidity and mortality from communicable diseases, rapidly declined. Recently many new pathogenic microbes were recognized: L. monocytogenes, Hantaan virus, Y. pseudotuberculosis, P. multocida, L. pneumophilia, Human immunodeficiency virus (HIV), G. seoi, H. capsulatum, C. burnetii, V. cholerae 0139, C. parvum, F. tularensis, E. coli 0157:H7, B. burgdorferi, S. Typhimurium DT104, Rotavirus, hepatitis C virus and so on. Since the first HIV infection recognized in 1985, the reported cases of infection and deaths from HIV/AIDS have been steady increased each year. Legionnaire's disease, E. coli 0157:H7 colitis, listeriosis and crytosporidiasis have been occurring just sporadically among immunocompromized cases. Many re-emerging communicable diseases were occurred in Korea: leptospirosis, malaria, endemic typhus, cholera, tsutsugamushi disease, salmonellosis, hepatitis A, shigellosis, mumps, measles, acute hemorrhagic conjunctivitis, brucellosis and so on. Leptospirosis and tsutsugamushi diseases have been noticed as major public health problems since 1980s. The malaria that had been virtually disappeared for a decade has reappeared from 1993 with striking increase of patients in recent 3-4 years. The distributions of salmonella and shigella serotypes have been changed a lot in recent few decades. Furthermore rapid emergence of antibiotic-resistant bacterial strains induces more difficult and complex problems in control of communicable diseases. We must recognize on the importance of environment and ecosystem conservation and careful prescription of anti-microbial agent in order to prevent communicable diseases.

Increased frequencies of aberrant sperm as indicators of mutagenic damage in mice.

Soares, E R; Sheridan, W; Haseman, J K; Segall, M

1979-02-01

We have tested the effects of TEM in 3 strains of mice using the sperm morphology assay. In addition, we have made an attempt to evaluate this test system with respect to experimental design, statistical problems and possible interlaboratory differences. Treatment with TEM results in significant increases in the percent of abnormally shaped sperm. These increases are readily detectable in sperm treated as spermatocytes and spermatogonial stages. Our data indicate possible problems associated with inter-laboratory variation in slide analysis. We have found that despite the introduction of such sources of variation, our data were consistent with respect to the effects of TEM. Another area of concern in the sperm morphology test is the presence of "outlier" animals. In our study, such animals comprised 4% of the total number of animals considered. Statistical analysis of the slides from these animals have shown that this problem can be dealt with and that when recognized as such, "outliers" do not effect the outcome of the sperm morphology assay.

Natural Products: An Alternative to Conventional Therapy for Dermatophytosis?

PubMed

Lopes, Graciliana; Pinto, Eugénia; Salgueiro, Lígia

2017-02-01

The increased incidence of fungal infections, associated with the widespread use of antifungal drugs, has resulted in the development of resistance, making it necessary to discover new therapeutic alternatives. Among fungal infections, dermatophytoses constitute a serious public health problem, affecting 20-25 % of the world population. Medicinal plants represent an endless source of bioactive molecules, and their volatile and non-volatile extracts are clearly recognized for being the historical basis of therapeutic health care. Because of this, the research on natural products with antifungal activity against dermatophytes has considerably increased in recent years. However, despite the recognized anti-dermatophytic potential of natural products, often advantageous face to commercial drugs, there is still a long way to go until their use in therapeutics. This review attempts to summarize the current status of anti-dermatophytic natural products, focusing on their mechanism of action, the developed pharmaceutical formulations and their effectiveness in human and animal models of infection.

Committee opinion no. 507: human trafficking.

PubMed

2011-09-01

Human trafficking is a widespread problem with estimates ranging from 14,000 to 50,000 individuals trafficked into the United States annually. This hidden population involves the commercial sex industry, agriculture, factories, hotel and restaurant businesses, domestic workers, marriage brokers, and some adoption firms. Because 80% of trafficked individuals are women and girls, women’s health care providers may better serve their diverse patient population by increasing their awareness of this problem. The exploitation of people of any race, gender, sexual orientation, or ethnicity is unacceptable at any time, in any place. The members of the American College of Obstetricians and Gynecologists should be aware of this problem and strive to recognize and assist their patients who are victims or who have been victims of human trafficking.

2000-01-01

A wide range of sources have pointed out the magnitude and depth of the social problems that trouble Latin America and the Caribbean and the risks that these problems pose for democracy. Although there are other issues that merit consideration, this article briefly outlines nine key social problems: 1) the increase in poverty, 2) the impact of poverty, 3) unemployment and informal employment, 4) deficiencies in public health, 5) problems in education, 6) the newly poor, 7) the erosion of the family, 8) increasing crime, and 9) the perverse cycle of socioeconomic exclusion. Solving these problems must not be delayed. It is urgent to move to a comprehensive view of development that achieves a different balance between economic and social policies, and that recognizes the indispensable role of these policies in achieving truly sustainable development. At stake are problems that not only concern resources, but also priorities, levels of equity, and the organization of society. Facing up to this poverty and inequity requires an in-depth assessment of these economic policies' social consequences, of the crucial subject of Latin American inequity--the greatest in the world--and of the role of social and public policies.

While effective and efficient solving of everyday problems is important in business domains, little is known about the effects of workplace monitoring on problem-solving performance. In a laboratory experiment, we explored the monitoring environment's effects on an individual's propensity to (1) establish pattern solutions to problems, (2) recognize when pattern solutions are no longer efficient, and (3) solve complex problems. Under three work monitoring regimes-no monitoring, human monitoring, and electronic monitoring-114 participants solved puzzles for monetary rewards. Based on research related to worker autonomy and theory of social facilitation, we hypothesized that monitored (versus non-monitored) participants would (1) have more difficulty finding a pattern solution, (2) more often fail to recognize when the pattern solution is no longer efficient, and (3) solve fewer complex problems. Our results support the first two hypotheses, but in complex problem solving, an interaction was found between self-assessed ability and the monitoring environment.

Actuator Placement Via Genetic Algorithm for Aircraft Morphing

NASA Technical Reports Server (NTRS)

Crossley, William A.; Cook, Andrea M.

2001-01-01

This research continued work that began under the support of NASA Grant NAG1-2119. The focus of this effort was to continue investigations of Genetic Algorithm (GA) approaches that could be used to solve an actuator placement problem by treating this as a discrete optimization problem. In these efforts, the actuators are assumed to be "smart" devices that change the aerodynamic shape of an aircraft wing to alter the flow past the wing, and, as a result, provide aerodynamic moments that could provide flight control. The earlier work investigated issued for the problem statement, developed the appropriate actuator modeling, recognized the importance of symmetry for this problem, modified the aerodynamic analysis routine for more efficient use with the genetic algorithm, and began a problem size study to measure the impact of increasing problem complexity. The research discussed in this final summary further investigated the problem statement to provide a "combined moment" problem statement to simultaneously address roll, pitch and yaw. Investigations of problem size using this new problem statement provided insight into performance of the GA as the number of possible actuator locations increased. Where previous investigations utilized a simple wing model to develop the GA approach for actuator placement, this research culminated with application of the GA approach to a high-altitude unmanned aerial vehicle concept to demonstrate that the approach is valid for an aircraft configuration.

The purposes of this 36-month study of children with first recognized seizures were: (1) to describe baseline differences in behavior problems between children with and without prior unrecognized seizures; (2) to identify differences over time in behavior problems between children with seizures and their healthy siblings; (3) to identify the proportions of children with seizures and healthy siblings who were consistently at risk for behavior problems for 36 months; and (4) to identify risk factors for behavior problems 36 months following the first recognized seizure. Risk factors explored included demographic (child age and gender, caregiver education), neuropsychological (IQ, processing speed), seizure (epileptic syndrome, use of antiepileptic drug, seizure recurrence), and family (family mastery, satisfaction with family relationships, parent response) variables. Participants were 300 children aged 6 through 14 years with a first recognized seizure and 196 healthy siblings. Data were collected from medical records, structured interviews, self-report questionnaires, and neuropsychological testing. Behavior problems were measured using the Child Behavior Checklist and the Teacher's Report Form. Data analyses included descriptive statistics and linear mixed models. Children with prior unrecognized seizures were at higher risk for behavior problems at baseline. As a group, children with seizures showed a steady reduction in behavior problems over time. Children with seizures were found to have significantly more behavior problems than their siblings over time, and significantly more children with seizures (11.3%) than siblings (4.6%) had consistent behavior problems over time. Key risk factors for child behavior problems based on both caregivers and teachers were: less caregiver education, slower initial processing speed, slowing of processing speed over the first 36 months, and a number of family variables including lower levels of family mastery or child satisfaction with family relationships, lower parent support of the child's autonomy, and lower parent confidence in their ability to discipline their child. Children with new-onset seizures who are otherwise developing normally have higher rates of behavior problems than their healthy siblings; however, behavior problems are not consistently in the at-risk range in most children during the first 3 years after seizure onset. When children show behavior problems, family variables that might be targeted include family mastery, parent support of child autonomy, and parents' confidence in their ability to handle their children's behavior.

Pesce, Renata

2009-01-01

This article presents a review of the world literature about two important subjects: family violence and problems of aggressive behavior and oppositional defiant disorder in childhood. We opted for publications that had used the CBCL- Child Behavior Checklist for investigating behavior problems in children. This instrument is internationally recognized for its reliability and validity, considered an efficient tool for identifying behavior problems in children. Our findings showed that marital violence predominated in the studies as kind of familiar violence able to cause problems of aggressiveness and transgression in children. Another point discussed was the lack of consensus on the terms used in the articles to refer to such behavior problems. The review showed the need for in-depth studies into this subject, mainly in the sense of thinking about prevention and health promotion in childhood and adolescence. Aggressive behavior in children tends to remain and increase over time, a fact that points to the need for strategies for preventing these problems in the school, familiar and health environments.

The problem of child sexual abuse is of increasing relevance to family physicians. Apart from the need to recognize and manage child victims and their families, it is important to be aware of the incidence and nature of the many sequelae of childhood sexual exploitation. Common signals include physical, psychosomatic, and psychiatric disorders. Some physicians must deal with their own childhood victimization if the best interests of their patients are to be served.

Increasingly recognized as a potential public health problem since the outbreak of Legionnaire's disease in Philadelphia in 1976, polluted indoor air has been associated with health problems that include asthma, sick building syndrome, multiple chemical sensitivity, and hypersensitivity pneumonitis. Symptoms are often nonspecific and include headache, eye and throat irritation, chest tightness and shortness of breath, and fatigue. Air-borne contaminants include commonly used chemicals, vehicular exhaust, microbial organisms, fibrous glass particles, and dust. Identified causes include defective building design and construction, aging of buildings and their ventilation systems, poor climate control, inattention to building maintenance. A major contributory factor is the explosion in the use of chemicals in building construction and furnishing materials over the past four decades. Organizational issues and psychological variables often contribute to the problem and hinder its resolution. This article describes the health problems related to poor indoor air quality and offers solutions. Images p398-a p399-a PMID:9769764

An environmental approach for used oil management in Asian cities: a Bangkok' s experience.

PubMed

Leong, Shing Tet; Laortanakul, Preecha

2003-11-01

This paper addresses increasing concern about the pollution threat of used oil being illegally dumped and the impact of oil on air pollution and freshwater ecosystems in Asian countries. Used oil is a very serious waste management problem. These results call for management action such as maximising the collection and recovery of used oil. The Thai government recognizes the need to recycle used oil and has been active in encouraging programs to accomplish this goal. Thus unless new approaches and incentives are developed, used oil generation may become an increasing serious problem to our environment. The purpose of this study is to examine the technical and economic feasibility, of recycling used oils. In addition, this paper briefly discusses the problems to be overcome and outlines potential mechanisms for providing the necessary disposal controls in order to maximize the protection to public health and environmental quality from potential hazards posed by used lube oil disposal.

Hippocampal-neocortical functional reorganization underlies children's cognitive development.

2014-09-01

The importance of the hippocampal system for rapid learning and memory is well recognized, but its contributions to a cardinal feature of children's cognitive development-the transition from procedure-based to memory-based problem-solving strategies-are unknown. Here we show that the hippocampal system is pivotal to this strategic transition. Longitudinal functional magnetic resonance imaging (fMRI) in 7-9-year-old children revealed that the transition from use of counting to memory-based retrieval parallels increased hippocampal and decreased prefrontal-parietal engagement during arithmetic problem solving. Longitudinal improvements in retrieval-strategy use were predicted by increased hippocampal-neocortical functional connectivity. Beyond childhood, retrieval-strategy use continued to improve through adolescence into adulthood and was associated with decreased activation but more stable interproblem representations in the hippocampus. Our findings provide insights into the dynamic role of the hippocampus in the maturation of memory-based problem solving and establish a critical link between hippocampal-neocortical reorganization and children's cognitive development.

2015-01-01

Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease state characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory process. It is increasingly recognized as a major public health problem, affecting more than 20 million adults in the US. It is also recognized as a leading cause of hospitalizations and is the fourth leading cause of death in the US. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) operates to promote evidence-based management of COPD, increase awareness and encourage research. In 2011, GOLD published a consensus report detailing evidence-based management strategies for COPD, which were last updated in 2015. In recent years, newer strategies and a growing number of new pharmacologic agents to treat symptoms of COPD have also been introduced and show promise in improving the management of COPD. We aim to provide an evidence-based review of the available and upcoming pharmacologic and non-pharmacologic treatment options for stable COPD, with continued emphasis on evidence-based management.

Building emotional intelligence: a strategy for emerging nurse leaders to reduce workplace bullying.

PubMed

Bennett, Karen; Sawatzky, Jo-Ann V

2013-01-01

Bullying is one of the most concerning forms of aggression in health care organizations. Conceptualized as an emotion-based response, bullying is often triggered by today's workplace challenges. Unfortunately, workplace bullying is an escalating problem in nursing. Bullying contributes to unhealthy and toxic environments, which in turn contribute to ineffective patient care, increased stress, and decreased job satisfaction among health care providers. These equate to a poor workforce environment, which in turn increases hospital costs when nurses choose to leave. Nurse managers are in positions of power to recognize and address negative workplace behaviors, such as bullying. However, emerging leaders in particular may not be equipped with the tools to deal with bullying and consequently may choose to overlook it. Substantive evidence from other disciplines supports the contention that individuals with greater emotional intelligence are better equipped to recognize early signs of negative behavior, such as bullying. Therefore, fostering emotional intelligence in emerging nurse leaders may lead to less bullying and more positive workplace environments for nurses in the future.

To determine the effect of computer-based medical teaching (CBMT) as a supplementary method to teach clinical problem-solving during the clerkship in neurology. Randomized controlled blinded study. Academic Medical Centre, Amsterdam, the Netherlands. 103 Students were assigned at random to a group with access to CBMT and a control group. CBMT consisted of 20 computer-simulated patients with neurological diseases, and was permanently available during five weeks to students in the CBMT group. The ability to recognize and solve neurological problems was assessed with two free-response tests, scored by two blinded observers. The CBMT students scored significantly better on the test related to the CBMT cases (mean score 7.5 on a zero to 10 point scale; control group 6.2; p < 0.001). There was no significant difference on the control test not related to the problems practised with CBMT. CBMT can be an effective method for teaching clinical problem-solving, when used as a supplementary teaching facility during a clinical clerkship. The increased ability to solve problems learned by CBMT had no demonstrable effect on the performance with other neurological problems.

The Focus Group Discussion (FGD) activity in Mathematical Physics learning has helped students perform the stages of problem solving reflectively. The FGD implementation was conducted to explore the problems and find the right strategy to improve the students' ability to solve the problem accurately which is one of reflective thinking component that has been difficult to improve. The research method used is descriptive qualitative by using single subject response in Physics student. During the FGD process, one student was observed of her reflective thinking development in solving the physics problem. The strategy chosen in the discussion activity was the Cognitive Apprenticeship-Instruction (CA-I) syntax. Based on the results of this study, it is obtained the information that after going through a series of stages of discussion, the students' reflective thinking skills is increased significantly. The scaffolding stage in the CA-I model plays an important role in the process of solving physics problems accurately. Students are able to recognize and formulate problems by describing problem sketches, identifying the variables involved, applying mathematical equations that accord to physics concepts, executing accurately, and applying evaluation by explaining the solution to various contexts.

Legislative and educational alternatives to a judicial remedy for the transfer trauma dilemma.

PubMed

Cohen, E S

1986-01-01

Transfer trauma is alleged to be an increase in morbidity and mortality in institutionally relocated chronically ill elderly. Efforts by the legal profession to persuade courts that transfer trauma should be a legally recognized phenomenon invoking judicial protections against transfer (the "transfer trauma argument") have been unproductive. In O'Bannon v. Town Court Nursing Center, Inc., the United States Supreme Court denied standing to elderly persons claiming a property interest in remaining in alleged substandard facilities. The Court rejected the argument that the possibility of transfer trauma constituted a deprivation of life or liberty that would have required due process protections of notice and hearing. Despite the Court's preclusion of transfer trauma litigation in a constitutional context and the general unwillingness of lower courts to recognize the phenomenon, attorneys continue to burden the judicial system with frivolous transfer trauma arguments. The unfruitful pursuit of a judicial remedy for the ethical and social problems that arise with relocation of the elderly continues, in part, because of a misguided belief that this distressing social phenomenon is best remedied by the courts. Judicial unwillingness to recognize the transfer trauma argument, however, does not preclude legislative consideration of the humanitarian issues concerning the institutional relocation of elderly persons. This Article examines gerontological research in order to understand the judicial rejection of the transfer trauma argument and argues in support of legislative and educational solutions for the ethical and social problems attending transfer.

Crew Communication as a Factor in Aviation Accidents

The crew communication process is analyzed. Planning and explanation are shown to be well-structured discourse types, described by formal rules. These formal rules are integrated with those describing the other most important discourse type within the cockpit: the command-and-control speech act chain. The latter is described as a sequence of speech acts for making requests (including orders and suggestions), for making reports, for supporting or challenging statements, and for acknowledging previous speech acts. Mitigation level, a linguistic indication of indirectness and tentativeness in speech, was an important variable in several hypotheses, i.e., the speech of subordinates is more mitigated than the speech of superiors, the speech of all crewmembers is less mitigated when they know that they are in either a problem or emergency situation, and mitigation is a factor in failures of crewmembers to initiate discussion of new topics or have suggestions ratified by the captain. Test results also show that planning and explanation are more frequently performed by captains, are done more during crew- recognized problems, and are done less during crew-recognized emergencies. The test results also indicated that planning and explanation are more frequently performed by captains than by other crewmembers, are done more during crew-recognized problems, and are done less during-recognized emergencies.

Lack of fast and strong microactuators is a well-recognized problem in MEMS community. Electrochemical actuators can develop high pressure but they are notoriously slow. Water electrolysis produced by short voltage pulses of alternating polarity can overcome the problem of slow gas termination. Here we demonstrate an actuation regime, for which the gas pressure is relaxed just for 10 μs or so. The actuator consists of a microchamber filled with the electrolyte and covered with a flexible membrane. The membrane bends outward when the pressure in the chamber increases. Fast termination of gas and high pressure developed in the chamber are related to a high density of nanobubbles in the chamber. The physical processes happening in the chamber are discussed so as problems that have to be resolved for practical applications of this actuation regime. The actuator can be used as a driving engine for microfluidics.

Expertise finding in bibliographic network: topic dominance learning approach.

Neshati, Mahmood; Hashemi, Seyyed Hadi; Beigy, Hamid

2014-12-01

Expert finding problem in bibliographic networks has received increased interest in recent years. This problem concerns finding relevant researchers for a given topic. Motivated by the observation that rarely do all coauthors contribute to a paper equally, in this paper, we propose two discriminative methods for realizing leading authors contributing in a scientific publication. Specifically, we cast the problem of expert finding in a bibliographic network to find leading experts in a research group, which is easier to solve. We recognize three feature groups that can discriminate relevant experts from other authors of a document. Experimental results on a real dataset, and a synthetic one that is gathered from a Microsoft academic search engine, show that the proposed model significantly improves the performance of expert finding in terms of all common information retrieval evaluation metrics.

Foodborne illness: new developments concerning an old problem.

PubMed

Kasowski, Eric J; Gackstetter, Gary D; Sharp, Trueman W

2002-08-01

Foodborne illnesses continue to cause substantial morbidity and mortality in the United States, primarily as gastroenteritis but occasionally as other syndromes as well. Most of these illnesses are caused by a variety of widely known infectious agents, principally viruses, and are probably the result of common mistakes in food handling in the home or in restaurants. The epidemiology of foodborne illness is evolving. Major changes in food production, distribution, and consumption have created opportunities for new pathogens to emerge and for old ones to reemerge, and the potential for widespread outbreaks is increasing. Antibiotic resistance in bacterial pathogens resulting from the widespread use of antimicrobial agents in animal husbandry is also an important concern. Clinicians must be aware of the changing epidemiology of foodborne illness to recognize and manage these conditions in the clinical setting. In addition, clinicians are critical in the reporting of recognized or suspected foodborne illness, so that public health authorities are able to investigate, understand, and ultimately better control them. A number of new techniques have been employed, and others under development will improve our ability to recognize and cope with foodborne diseases.

The co-occurrence of mental health and substance use disorders is becoming increasingly recognized as a single problem, and professionals recognize that both should be addressed at the same time. Medical best practices recommend integrated treatment. However, criticisms have arisen, particularly concerning the difficulty of implementing integrated teams in specific health-care contexts and the appropriateness of the proposed model for certain populations. Using logic analysis, we identify the key clinical and organizational factors that contribute to successful implementation. Building on both the professional and organizational literatures on integrated services, we propose a conceptual model that makes it possible to analyze integration processes and places integrated treatment within an interpretative framework. Using this model, it becomes possible to identify key factors necessary to support service integration, and suggest new models of practice adapted to particular contexts.

What is the evidence for retrieval problems in the elderly?

PubMed

White, N; Cunningham, W R

1982-01-01

To determine whether older adults experience particular problems with retrieval, groups of young and elderly adults were given free recall and recognition tests of supraspan lists of unrelated words. Analysis of number of words correctly recalled and recognized yielded a significant age by retention test interaction: greater age differences were observed for recall than for recognition. In a second analysis of words recalled and recognized, corrected for guessing, the interaction disappeared. It was concluded that previous interpretations that age by retention test interactions are indicative of retrieval problems of the elderly may have been confounded by methodological problems. Furthermore, it was suggested that researchers in aging and memory need to be explicit in identifying their underlying models of error processes when analyzing recognition scores: different error models may lead to different results and interpretations.

Environmental implications of plastic debris in marine settings—entanglement, ingestion, smothering, hangers-on, hitch-hiking and alien invasions

Over the past five or six decades, contamination and pollution of the world’s enclosed seas, coastal waters and the wider open oceans by plastics and other synthetic, non-biodegradable materials (generally known as ‘marine debris’) has been an ever-increasing phenomenon. The sources of these polluting materials are both land- and marine-based, their origins may be local or distant, and the environmental consequences are many and varied. The more widely recognized problems are typically associated with entanglement, ingestion, suffocation and general debilitation, and are often related to stranding events and public perception. Among the less frequently recognized and recorded problems are global hazards to shipping, fisheries and other maritime activities. Today, there are rapidly developing research interests in the biota attracted to freely floating (i.e. pelagic) marine debris, commonly known as ‘hangers-on and hitch-hikers’ as well as material sinking to the sea floor despite being buoyant. Dispersal of aggressive alien and invasive species by these mechanisms leads one to reflect on the possibilities that ensuing invasions could endanger sensitive, or at-risk coastal environments (both marine and terrestrial) far from their native habitats.

Can False Memories Prime Problem Solutions for Healthy Older Adults and those with Alzheimer 's Disease?

PubMed

Akhtar, Shazia; Howe, Mark L; Hoepstine, Kedron

2018-06-05

Recent research has shown that false memories can have a positive consequence on human cognition in both children and young adults. The present experiment investigated whether false memories could have similar positive effects by priming solutions to insight-based problems in healthy older adults and people with Alzheimer's disease. Participants were asked to solve compound remote associate task (CRAT) problems, half of which had been preceded by the presentation of Deese/Roediger-McDermott (DRM) lists whose critical lures were also the solutions to those problems. The results showed that regardless of cognitive ability, when the critical lure was falsely recognized, CRAT problems were solved more often and reliably faster than problems that were not primed by a DRM list. When the critical lure was not falsely recognized, CRAT problem solution rates and times were no different from when there was no DRM priming. These findings are consistent with predictions from theories of associative activation and demonstrate the importance of automatic spreading activation processes in memory across the lifespan.

Psychiatric Aspects of Dementia

Purpose of Review: The psychiatric aspects of dementia are increasingly recognized as significant contributors to distress, disability, and care burden, and, thus, are of increasing interest to practicing neurologists. This article examines how psychiatric disorders are entwined with dementia and describes the predictive, diagnostic, and therapeutic implications of the psychiatric symptoms of dementia. Recent Findings: Psychiatric disorders, particularly depression and schizophrenia, are associated with higher risk for late-life dementia. Psychiatric phenomena also define phenotypes such as frontotemporal dementia and dementia with Lewy bodies, cause distress, and amplify dementia-related disabilities. Management requires a multidisciplinary team, a problem-solving stance, programs of care, and pharmacologic management. Recent innovations include model programs that provide structured problem-solving interventions and tailored in-home care. Summary: There is new appreciation of the complexity of the relationship between psychiatric disorders and dementia as well as the significance of this relationship for treatment, community services, and research.

Recently, recognizing a user's daily activity using a smartphone and wearable sensors has become a popular issue. However, in contrast with the ideal definition of an experiment, there could be numerous complex activities in real life with respect to its various background and contexts: time, space, age, culture, and so on. Recognizing these complex activities with limited low-power sensors, considering the power and memory constraints of the wearable environment and the user's obtrusiveness at once is not an easy problem, although it is very crucial for the activity recognizer to be practically useful. In this paper, we recognize activity of eating, which is one of the most typical examples of a complex activity, using only daily low-power mobile and wearable sensors. To organize the related contexts systemically, we have constructed the context model based on activity theory and the "Five W's", and propose a Bayesian network with 88 nodes to predict uncertain contexts probabilistically. The structure of the proposed Bayesian network is designed by a modular and tree-structured approach to reduce the time complexity and increase the scalability. To evaluate the proposed method, we collected the data with 10 different activities from 25 volunteers of various ages, occupations, and jobs, and have obtained 79.71% accuracy, which outperforms other conventional classifiers by 7.54-14.4%. Analyses of the results showed that our probabilistic approach could also give approximate results even when one of contexts or sensor values has a very heterogeneous pattern or is missing.

What Is Evidence-Based Behavior Analysis?

PubMed Central

Smith, Tristram

2013-01-01

Although applied behavior analysts often say they engage in evidence-based practice, they express differing views on what constitutes “evidence” and “practice.” This article describes a practice as a service offered by a provider to help solve a problem presented by a consumer. Solving most problems (e.g., increasing or decreasing a behavior and maintaining this change) requires multiple intervention procedures (i.e., a package). Single-subject studies are invaluable in investigating individual procedures, but researchers still need to integrate the procedures into a package. The package must be standardized enough for independent providers to replicate yet flexible enough to allow individualization; intervention manuals are the primary technology for achieving this balance. To test whether the package is effective in solving consumers' problems, researchers must evaluate outcomes of the package as a whole, usually in group studies such as randomized controlled trials. From this perspective, establishing an evidence-based practice involves more than analyzing the effects of discrete intervention procedures on behavior; it requires synthesizing information so as to offer thorough solutions to problems. Recognizing the need for synthesis offers behavior analysts many promising opportunities to build on their existing research to increase the quality and quantity of evidence-based practices.

It is widely recognized that early onset of disruptive behavior is linked to a variety of detrimental outcomes in males, later in life. In contrast, little is known about the association between girls' childhood trajectories of disruptive behavior and adjustment problems in early adolescence. This study used nine waves of data from the ongoing Pittsburgh Girls Study. A semiparametric group-based model was used to identify trajectories of disruptive behavior in 1,513 girls from age 6 to 12 years. Adjustment problems were characterized by depression, self-harm, Post Traumatic Stress Disorder (PTSD), substance use, interpersonal aggression, sexual behavior, affiliation with delinquent peers, and academic achievement at ages 13 and 14. Three trajectories of childhood disruptive behavior were identified: low, medium, and high. Girls in the high group were at increased risk for depression, self-harm, PTSD, illegal substance use, interpersonal aggression, early and risky sexual behavior, and lower academic achievement. The likelihood of multiple adjustment problems increased with trajectories reflecting higher levels of disruptive behavior. Girls following the high childhood trajectory of disruptive behavior require early intervention programs to prevent multiple, adverse outcomes in adolescence and further escalation in adulthood. © 2014 Association for Child and Adolescent Mental Health.

Effects of health and safety problem recognition on small business facility investment

PubMed Central

2013-01-01

Objectives This study involved a survey of the facility investment experiences, which was designed to recognize the importance of health and safety problems, and industrial accident prevention. Ultimately, we hope that small scale industries will create effective industrial accident prevention programs and facility investments. Methods An individual survey of businesses’ present physical conditions, recognition of the importance of the health and safety problems, and facility investment experiences for preventing industrial accidents was conducted. The survey involved 1,145 business operators or management workers in small business places with fewer than 50 workers in six industrial complexes. Results Regarding the importance of occupational health and safety problems (OHS), 54.1% said it was “very important”. Received technical and financial support, and industrial accidents that occurred during the past three years were recognized as highly important for OHS. In an investigation regarding facility investment experiences for industrial accident prevention, the largest factors were business size, greater numbers of industrial accidents, greater technical and financial support received, and greater recognition of the importance of the OHS. The related variables that decided facility investment for industry accident prevention in a logistic regression analysis were the experiences of business facilities where industrial accidents occurred during the past three years, received technical and financial support, and recognition of the OHS. Those considered very important were shown to be highly significant. Conclusions Recognition of health and safety issues was higher when small businesses had experienced industrial accidents or received financial support. The investment in industrial accidents was greater when health and safety issues were recognized as important. Therefore, the goal of small business health and safety projects is to prioritize health and safety issues in terms of business management and recognition of importance. Therefore, currently various support projects are being conducted. However, there are issues regarding the limitations of the target businesses and inadequacies in maintenance and follow-up. Overall, it is necessary to provide various incentives for onsite participation that can lead to increased recognition of health and safety issues and practical investments, while perfecting maintenance and follow up measures by thoroughly revising existing operating systems.

Sullivan, C; Yuan, C

1995-01-01

Workplace violence is becoming increasingly recognized as a serious problem in health care settings. All 628 workers' compensation assaults claimed by minority Los Angeles County health care workers from 1986 through 1990 were abstracted. Population-at-risk data from county personnel computer tapes provided denominators by age, sex, race, job classification, and type of facility. Rates varied by type of facility (rate ratio = 38 for psychiatric hospitals vs public health facilities) and varied by job, with inpatient nursing attendants having the highest rate for caregivers. Most assaults were committed by patients (86%), followed by coworkers (8%). The average cost of an assault ($4879) was relatively low but related to the costlier problem of work-related emotional illness. PMID:7604900

Polysaccharide-Based Membranes in Food Packaging Applications.

Plastic packaging is essential nowadays. However, the huge environmental problem caused by landfill disposal of non-biodegradable polymers in the end of life has to be minimized and preferentially eliminated. The solution may rely on the use of biopolymers, in particular polysaccharides. These macromolecules with film-forming properties are able to produce attracting biodegradable materials, possibly applicable in food packaging. Despite all advantages of using polysaccharides obtained from different sources, some drawbacks, mostly related to their low resistance to water, mechanical performance and price, have hindered their wider use and commercialization. Nevertheless, with increasing attention and research on this field, it has been possible to trace some strategies to overcome the problems and recognize solutions. This review summarizes some of the most used polysaccharides in food packaging applications.

Louisiana's statewide beach cleanup

USGS Publications Warehouse

Lindstedt, Dianne M.; Holmes, Joseph C.

1989-01-01

Litter along Lousiana's beaches has become a well-recognized problem. In September 1987, Louisiana's first statewide beach cleanup attracted about 3300 volunteers who filled 16,000 bags with trash collected along 15 beaches. An estimated 800,173 items were gathered. Forty percent of the items were made of plastic and 11% were of polystyrene. Of all the litter collected, 37% was beverage-related. Litter from the oil and gas, commercial fishing, and maritime shipping industries was found, as well as that left by recreational users. Although beach cleanups temporarily rid Louisiana beaches of litter, the real value of the effort is in public participation and education. Civic groups, school children, and individuals have benefited by increasing their awareness of the problems of trash disposal.

A systemic approach to occupational and environmental health.

2005-01-01

As the corporate role in occupational and public health receives increased scrutiny, it is essential to recognize that it is not sufficient to identify specific acts of malfeasance or influence, or even to campaign to address them. A more comprehensive and systemic framework for understanding the role of corporations requires consideration of corporate power and its effects as endemic features of national socioeconomic systems and the rapidly integrating global order. The underlying social structures that produce social and environmental problems, and undermine reform, make systemic change necessary. Identifying this "structure of harm" provides important implications for researchers, policymakers, activists, and others trying to address environmental and social problems, particularly with regard to integrating efforts to address immediate impacts with those for longer-term, systemic change.

Ergonomic risk factors associated with clinical dentistry.

Rucker, Lance M; Sunell, Susanne

2002-02-01

Ergonomics has formed an integral aspect of dental education at the University of British Columbia since the early 1980s. However, studies continued to indicate that dentists are at risk for developing musculoskeletal problems. This provided the impetus for a study of the risk factors associated with these problems. The data analyzed from 421 survey respondents in British Columbia indicate that indeed dentists are experiencing musculoskeletal pain and discomfort. However, the data also suggest that dentists can recognize and identify their own postures, practicing positions, and the equipment usage patterns that are associated with increased risks of experiencing musculoskeletal pain and discomfort. Such recognition is the first critical step to avoiding or neutralizing ergonomic habits and work environment layouts that might otherwise unnecessarily shorten professional clinical careers.

The systemic fungal invasions are recognized with increasing frequency and constitute a primary cause of morbidity and mortality, especially in immunocompromised patients. Early diagnosis improves prognosis, but remains a problem because there is lack of sensitive tests to aid in the diagnosis of systemic mycoses on the one hand, and on the other the patients only present unspecific signs and symptoms, thus delaying early diagnosis. The diagnosis depends upon a combination of clinical observation and laboratory investigation. The successful laboratory diagnosis of fungal infection depends in major part on the collection of appropriate clinical specimens for investigations and on the selection of appropriate microbiological test procedures. So these problems (collection of specimens, direct techniques, staining methods, cultures on different media and non-culture-based methods) are presented in article.

Multimedia article. The keys to the new laparoscopic world Thumbs up! knot and Tornado knot.

Uchida, K; Haruta, N; Okajima, M; Matsuda, M; Yamamoto, M

2005-06-01

Most laparoscopic surgeons feel some anxiety when performing intracorporeal knotting with conventional techniques [1, 2]. Two factors contribute to this anxiety. The first is the necessity of recognizing three dimensions on a two-dimensional monitor. The conventional intracorporeal knotting techniques make loops by twisting the thread with a second pair of forceps. This necessitates cooperative movement of both hands, with the added difficulties of depth perception. Regular touch confirmations reduce problems with depth perception. However, touch confirmation is more complicated in laparoscopic surgery than in laparotomy. The second problem is that tied loops can come loose and escape the instruments, especially with hard thread. This is not only stressful but also increases operation time.

Lean Perspectives: A Case for Implementing Parent-Child Relational Problem Screening.

PubMed

Okeoma, Bryson C

2018-04-17

The purpose of the current study was to make a case for instituting parent-child relational problem (PCRP) screening as a standard of care in pediatric inpatient psychiatric units due to increasing evidence that PCRP may be an underreported problem that affects more adolescents than currently realized. Adolescents who are admitted to the hospital for mood exacerbation, suicidal ideation, self-harm behavior, or behavioral escalation may improve and be discharged. However, these adolescents often are readmitted, which may be associated with parent-child relational factors. By identifying adolescents with PCRP and initiating holistic therapy/intervention that addresses the underlying cause of their PCRP, it may be possible to improve the parent-adolescent relationship and break the cycle of admission, discharge, and readmission. PCRP is increasingly recognized as a risk factor for development and progression of childhood mental illnesses. Investment in screening and treatment for PCRP may result in significant cost savings from prevention or reduction of rehospitalization and/or amelioration of disability.

Hypnosis in nursing practice--emphasis on the "problem patient' who has pain--Part II.

PubMed

Zahourek, R P

1982-04-01

The program of treating burned patients with hypnosis was expanded to treating multi-problem and chronic pain patients on the same surgical unit at Denver General Hospital. The majority of patients received some benefit. Many gained control over intense pain and many increased their sense of self-esteem and mastery. The behavioral problems diminished and the staff became reinterested and reinvolved with these very needy people. Whether or not nurses elect to practice hypnosis, the principles are familiar and can be added to the repertory of nursing practice. Physical and psychological relaxation relieves distress and potentiates patients' comfort with or without pain medication. Communicate to the patient that what you are doing builds confidence and increases the probability that treatment wil be effective. Furthermore, recognizing imaginary capacities as powerful in promoting comfort adds an option for intervention not always considered or used by nurses. Whether or not nurses describe what they do as "hypnosis," the use of these techniques can be useful to their practice and to the patients in whom they attempt to alleviate suffering and promote comfort and growth.

Teaching doctors to treat doctors: medical student peer counselling.

Physicians' emotional problems need to be recognized and treated. Intervention and prevention in this problem area have been attempted at the Medical College of Wisconsin through a programme of peer counselling designed to teach student physicians how to recognize and treat emotional difficulties faced by their peers. During the 18 months that the programme has been in operation, 20 peer counsellors reported a total 1,185 hours spent in counselling their peers, lending credence to the speculation that doctors will turn to their peers for help if, in medical school, there is acceptance of fallibility and responsiveness on the part of peers.

Mexico City Metropolitan Zone (MCMZ) represents an example of a megacity where the air pollution problem has reached an important evolution in a very short time, causing a risk in the health of a population of more than 20 million inhabitants. The atmospheric pollution problem in the MCMZ, began several decades ago, but it increased drastically in the middle of the 80`s. It is important to recognize that in the 60`s, 70`s and the first half of the 80`s the main pollutants were sulfur dioxide and total suspended particles. However since the second half of the 80`s until now, ozonemore » is the most important air pollutant besides of the suspended particles (PM{sub 10}) and other toxic pollutants (1--8). The purpose of this paper is to discuss the evolution of the ozone atmospheric pollution problem in the MCMZ, as well as to analyze the results of several implemented air pollution control strategies.« less

Concerns about deficiencies in the quality of care delivered in US hospitals grew during a time period when an increasing number of hospitals were experiencing financial problems. Our study examines a six-year longitudinal database of general acute care hospitals in 11 states to assess the relationship between hospital financial condition and quality of care. We evaluate two measures of financial performance: operating margin and a broader profitability measure that encompasses both operating and non-operating sources of income. Our model specification allows for gradual adjustments in quality-enhancing activities and recognizes that current realizations of patient quality may affect future financial performance. Empirical results suggest that there is a relationship between financial performance and quality of care, but not as strong as suggested in earlier research. Overall, our results suggest that deep financial problems that go beyond the patient care side of business may be important to prompting quality problems. Copyright (c) 2007 John Wiley & Sons, Ltd.

Children's competence or adults' incompetence: different developmental trajectories in different tasks.

2013-08-01

Dual-process theories have been proposed to explain normative and heuristic responses to reasoning and decision-making problems. Standard unitary and dual-process theories predict that normative responses should increase with age. However, research has focused recently on exceptions to this standard pattern, including developmental increases in heuristic or intuitive responses. Developmental trends for normative and heuristic responses were investigated for 2 kinds of causal reasoning (if-only and covariation) problems in 2 experiments. To investigate the role of superstitious thinking in these developmental trends, in both experiments a superstitious element was added to the problem solved by half the participants. In the first experiment, 90 fifth graders, 99 seventh graders, and 153 adults responded to an if-only problem. Children performed better than adults, with normative responses decreasing and heuristic responses increasing with age. A superstitious jinx intended to reduce heuristic responses had little effect for all age groups. In the second experiment, 276 fifth graders, 344 seventh graders, and 90 adults responded to a covariation-detection problem. When win-loss ratios were equal, adults performed better than children, with normative responses increasing and heuristic responses decreasing with age. When win-loss ratios were strikingly different, however, even the youngest children were able to solve the problems correctly; participants of all ages responded about equally well. When the normative response required recognizing that a good-luck ritual led to better team performance, participants in all age groups responded skeptically that the ritual had no effect, illustrating belief bias. These results are discussed in terms of dual-process theories and the development of heuristic (or intuitive) and analytical processes. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

Recognition and Prevention of Nosocomial Malnutrition: A Review and A Call to Action!

PubMed

Kirkland, Lisa L; Shaughnessy, Erin

2017-12-01

Nosocomial malnutrition in hospitalized adults is a morbid, costly, and potentially preventable and treatable problem. Although recognized as contributing to many serious complications of hospitalization, malnutrition is often missed when present on admission and rarely diagnosed if it occurs during hospital stay. Many routine clinical practices such as holding nutrition for testing or failing to address poor intake, when added to acute inflammatory disease states, cause rapid deterioration in nutritional status in up to 70% of inpatients. Malnutrition during hospitalization is associated with increased mortality for years after discharge. In addition, unrecognized (and under-coded) malnutrition is associated with potential lost revenues for hospital systems. Low-cost interventions of recognizing at-risk patients and providing adequate nutrition have the potential to improve patient outcomes and reduce health care costs. Physicians must champion implementation of these interventions, using guidance from national organizations. Copyright © 2017 Elsevier Inc. All rights reserved.

Beyond the limitations of best practices: How logic analysis helped reinterpret dual diagnosis guidelines

Brousselle, Astrid; Lamothe, Lise; Mercier, Céline; Perreault, Michel

2012-01-01

The co-occurrence of mental health and substance use disorders is becoming increasingly recognized as a single problem, and professionals recognize that both should be addressed at the same time. Medical best practices recommend integrated treatment. However, criticisms have arisen, particularly concerning the difficulty of implementing integrated teams in specific health-care contexts and the appropriateness of the proposed model for certain populations. Using logic analysis, we identify the key clinical and organizational factors that contribute to successful implementation. Building on both the professional and organizational literatures on integrated services, we propose a conceptual model that makes it possible to analyze integration processes and places integrated treatment within an interpretative framework. Using this model, it becomes possible to identify key factors necessary to support service integration, and suggest new models of practice adapted to particular contexts. PMID:17689316

Stroke survivors' views and experiences on impact of visual impairment.

PubMed

Rowe, Fiona J

2017-09-01

We sought to determine stroke survivors' views on impact of stroke-related visual impairment to quality of life. Stroke survivors with visual impairment, more than 1 year post stroke onset, were recruited. Semistructured biographical narrative interviews were audio-recorded and transcribed verbatim. A thematic approach to analysis of the qualitative data was adopted. Transcripts were systematically coded using NVivo10 software. Thirty-five stroke survivors were interviewed across the UK: 16 females, 19 males; aged 20-75 years at stroke onset. Five qualitative themes emerged: "Formal care," "Symptoms and self," "Adaptations," "Daily life," and "Information." Where visual problems existed, they were often not immediately recognized as part of the stroke syndrome and attributed to other causes such as migraine. Many participants did not receive early vision assessment or treatment for their visual problems. Visual problems included visual field loss, double vision, and perceptual problems. Impact of visual problems included loss in confidence, being a burden to others, increased collisions/accidents, and fear of falling. They made many self-identified adaptations to compensate for visual problems: magnifiers, large print, increased lighting, use of white sticks. There was a consistent lack of support and provision of information about visual problems. Poststroke visual impairment causes considerable impact to daily life which could be substantially improved by simple measures including early formal visual assessment, management and advice on adaptive strategies and self-management options. Improved education about poststroke visual impairment for the public and clinicians could aid earlier diagnosis of visual impairments.

Treating Sleep Problems in Patients with Schizophrenia.

Sleep disturbance is increasingly recognized as a major problem for patients with schizophrenia but it is rarely the direct focus of treatment. The main recommended treatment for insomnia is cognitive behavioural therapy, which we have been evaluating for patients with current delusions and hallucinations in the context of non-affective psychosis. In this article we describe the lessons we have learned about clinical presentations of sleep problems in schizophrenia and the adaptations to intervention that we recommend for patients with current delusions and hallucinations. Twelve factors that may particularly contribute to sleep problems in schizophrenia are identified. These include delusions and hallucinations interfering with sleep, attempts to use sleep as an escape from voices, circadian rhythm disruption, insufficient daytime activity, and fear of the bed, based upon past adverse experiences. Specific adaptations for psychological treatment related to each factor are described. Our experience is that patients want help to improve their sleep; sleep problems in schizophrenia should be treated with evidence-based interventions, and that the interventions may have the added benefit of lessening the psychotic experiences. A treatment technique hierarchy is proposed for ease of translation to clinical practice.

Dental Erosion and Medical Conditions: An Overview of Aetiology, Diagnosis and Management.

PubMed

Paryag, A; Rafeek, R

2014-09-01

Tooth wear or tooth surface loss is a normal physiological process and occurs throughout life but is considered pathological when the degree of destruction is excessive or the rate of loss is rapid, causing functional, aesthetic or sensitivity problems. The importance of tooth wear as a dental problem has been increasingly recognized. The findings of a study in Trinidad indicate that the prevalence of tooth wear in a Trinidadian population is comparable to the United Kingdom (UK) and, indeed, that the level of moderate and severe wear is in fact nearly twice as high. The aetiology of tooth wear is attributed to four causes: erosion, attrition, abrasion and abfraction. Erosion is generally considered to be the most prevalent cause of tooth wear in the UK and Europe. Acids that cause dental erosion originate mainly from the diet or the stomach and to a lesser extent, the environment. Underlying medical problems can contribute to the progress of tooth wear due to erosion and the patient may not be aware of these conditions. Moderate to severe tooth wear poses a significant clinical challenge to dental practitioners and may result in treatment that is more complex and costly to the patient both in terms of finances and time spent in the dental chair. This paper provides an overview of aetiology and diagnosis of tooth wear, in particular tooth wear due to erosion, so that medical and dental practitioners may recognize tooth wear early, institute preventive measures and manage patients appropriately.

Recognizing simple polyhedron from a perspective drawing

NASA Astrophysics Data System (ADS)

Zhang, Guimei; Chu, Jun; Miao, Jun

2009-10-01

Existed methods can't be used for recognizing simple polyhedron. In this paper, three problems are researched. First, a method for recognizing triangle and quadrilateral is introduced based on geometry and angle constraint. Then Attribute Relation Graph (ARG) is employed to describe simple polyhedron and line drawing. Last, a new method is presented to recognize simple polyhedron from a line drawing. The method filters the candidate database before matching line drawing and model, thus the recognition efficiency is improved greatly. We introduced the geometrical characteristics and topological characteristics to describe each node of ARG, so the algorithm can not only recognize polyhedrons with different shape but also distinguish between polyhedrons with the same shape but with different sizes and proportions. Computer simulations demonstrate the effectiveness of the method preliminarily.

Complex Human Activity Recognition Using Smartphone and Wrist-Worn Motion Sensors.

Shoaib, Muhammad; Bosch, Stephan; Incel, Ozlem Durmaz; Scholten, Hans; Havinga, Paul J M

2016-03-24

The position of on-body motion sensors plays an important role in human activity recognition. Most often, mobile phone sensors at the trouser pocket or an equivalent position are used for this purpose. However, this position is not suitable for recognizing activities that involve hand gestures, such as smoking, eating, drinking coffee and giving a talk. To recognize such activities, wrist-worn motion sensors are used. However, these two positions are mainly used in isolation. To use richer context information, we evaluate three motion sensors (accelerometer, gyroscope and linear acceleration sensor) at both wrist and pocket positions. Using three classifiers, we show that the combination of these two positions outperforms the wrist position alone, mainly at smaller segmentation windows. Another problem is that less-repetitive activities, such as smoking, eating, giving a talk and drinking coffee, cannot be recognized easily at smaller segmentation windows unlike repetitive activities, like walking, jogging and biking. For this purpose, we evaluate the effect of seven window sizes (2-30 s) on thirteen activities and show how increasing window size affects these various activities in different ways. We also propose various optimizations to further improve the recognition of these activities. For reproducibility, we make our dataset publicly available.

Recognition of skin cancer and sun protective behaviors in skin of color.

Sun protective behaviors are not as frequently practiced in skin of color as they are amongst Caucasians.1 Thus providing a reasonable assumption this behavior, or lack thereof, increases the risk of skin cancer in this skin of color populations. The aim of this study was two-fold-- the first was to understand whether patients with skin of color, when categorized by ethnicity or skin type, are able to recognize skin cancer lesions. The second was to examine the correlation between ethnicity and/or skin type and practice of sun protective behaviors. We surveyed 105 respondents presenting for various skin problems in a dermatology office in Chicago, IL. Topics covered in the survey included recognition of skin cancer appearance and choice of sun protective behaviors. We show that there is a tendency for patients to potentially recognize atypical pigmented lesions when they are "dark moles with irregular borders" or "new moles". In contrast, there is a reduced ability among darkly pigmented skin types IV to VI, to recognize non-melanoma skin cancers. We also show that in addition to ethnicity, skin type within ethnic groups may also play an influential role on the decision to protect or not protect oneself from the sun.

Modular Bayesian Networks with Low-Power Wearable Sensors for Recognizing Eating Activities

PubMed Central

Kim, Kee-Hoon

2017-01-01

Recently, recognizing a user’s daily activity using a smartphone and wearable sensors has become a popular issue. However, in contrast with the ideal definition of an experiment, there could be numerous complex activities in real life with respect to its various background and contexts: time, space, age, culture, and so on. Recognizing these complex activities with limited low-power sensors, considering the power and memory constraints of the wearable environment and the user’s obtrusiveness at once is not an easy problem, although it is very crucial for the activity recognizer to be practically useful. In this paper, we recognize activity of eating, which is one of the most typical examples of a complex activity, using only daily low-power mobile and wearable sensors. To organize the related contexts systemically, we have constructed the context model based on activity theory and the “Five W’s”, and propose a Bayesian network with 88 nodes to predict uncertain contexts probabilistically. The structure of the proposed Bayesian network is designed by a modular and tree-structured approach to reduce the time complexity and increase the scalability. To evaluate the proposed method, we collected the data with 10 different activities from 25 volunteers of various ages, occupations, and jobs, and have obtained 79.71% accuracy, which outperforms other conventional classifiers by 7.54–14.4%. Analyses of the results showed that our probabilistic approach could also give approximate results even when one of contexts or sensor values has a very heterogeneous pattern or is missing.

Renewable energy resources are widely recognized as an alternative to environmentally harmful fossil fuels. More renewable energy technologies will need to penetrate into fossil fuel dominated energy systems to mitigate the globally witnessed climate changes and environmental pollutions. It is necessary to prepare for the potential problems with increased proportions of renewable energy in the energy system, to prevent higher costs and decreased reliability. Motivated by this need, this paper addresses the operation of an energy system with an energy storage system in the context of developing a decision-supporting framework.

Adolescents' suicidal thinking and reluctance to consult general medical practitioners.

Wilson, Coralie J; Deane, Frank P; Marshall, Kellie L; Dalley, Andrew

2010-04-01

Appropriate help-seeking is widely recognized as a protective factor, and vital for early treatment and prevention of mental health problems during adolescence. General medical practitioners (GPs), that is, family doctors, provide a vital role in the identification of adolescents with mental health problems and the provision of treatment as well as access to other specialists in mental health care services. The current study examined the association between suicidal ideation and intentions to seek help from a GP for suicidal thoughts, emotional problems and physical health problems, using a sample of 590 Australian high school students that was 56.7% female and aged 13-18 years (M = 15.56 years, SD = .66 years). Higher levels of suicidal ideation and general psychological distress were related to lower intentions to seek help from a GP for suicidal and physical problems. The results suggest that even at subclinical levels, increases in suicidal ideation or psychological distress may lead to help avoidance. School personnel and other gatekeepers need to be aware of this trend in order to be more assertive in encouraging and supporting appropriate help-seeking for mental health problems. School health promotion programs should consider including information to explicitly address the help-negation process.

Are you treating youngsters who are or should be receiving mental health services?

PubMed

Waldman, H B

1996-01-01

Psychiatrists now recognize that the disorders of children are serious, treatable conditions and as precursors of adult psychopathology. These conditions can seriously influence the patient's behavior when undergoing dental treatment. The dentist will probably assume that the behavior problems are directly related to the nature of the dental service, rather than particular underlying personality characteristics of preschool and school-age children. It is important that practitioners recognize and understand these conditions as they attempt to provide adequate treatment. No national epidemiological studies have been conducted in this country that would provide valid indicators of either the prevalence or incidence of mental disorders among children. Local studies, however, have been done that diagnosable disorders in children range from 17.6 percent to 22 percent, including 3 percent to 5 percent who have severe emotional or behavioral problems. The prevalence of many mental disorders is greater in males than in females, ranging from a ratio of 2:1 to 9:1. Lifetime prevalence of mental disorders, first diagnosed in infancy, childhood, and adolescence range as high as 15,000 cases per 100,000 persons. It is important for the dentist to recognize that (1) even the youngest of children seen in a dental practice may be in need of mental health services, (2) management problems may stem from mental health problems, and (3) families are unaware or unwilling to admit that a child may need help.

2017-05-01

This article reviews the biology, prevalence and risks for obesity in people and companion dogs and cats, and explores the links between obesity and diabetes mellitus and cancer across these species. Obesity is a major healthcare problem in both human and veterinary medicine and there is an increasing prevalence of obesity in people and pets. In people and animals, obesity is a complex disorder involving diet, level of physical activity, behavioural factors, socioeconomic factors, environment exposures, genetics, metabolism and the microbiome. Pets and people share a number of obesity-related comorbidities. Obesity is a major risk factor for type 2 diabetes mellitus in people and in cats, but this association is not recognized in dogs. Obesity is a recognized risk factor for a number of human cancers, but there are fewer data available describing this association with canine neoplastic disease. One approach to addressing the problem of obesity is by taking a 'One Health' perspective. Comparative clinical research examining shared lifestyle and environmental risk factors and the reasons underlying species differences should provide new perspectives on the fundamental biology of obesity. One Health programmes involving human healthcare professionals and veterinarians could help address obesity with simple interventions at the community level. Copyright © 2017 The Author(s).

Violence against women.

In India, violence against women is increasing and takes many forms while laws to protect women are ignored. Despite this fact, the new reproductive and child health program ignores sexual violence. Health personnel can respond by: 1) accepting the magnitude of the problem; 2) investigating the deaths of young women; 3) documenting findings; 4) ensuring that sexual abuse is recognized as a public health problem; 5) disseminating findings; 6) ensuring the protection of female field workers; 7) recognizing violence as an occupational health hazard; 8) facilitating the empowerment of women; 9) training women in self-defense; 10) ensuring that colleges and training institutes address violence as a women's health concern; 11) studying the psychological effects of violence; 12) collaborating with the National Commission for Women and the National Human Rights Commission; and 13) advocating for incorporation of sexual violence as a reproductive health issue in the national reproductive health program. In particular, domestic violence is a pervasive violation of women's human rights and has been resistant to social advances because of its "hidden" nature. Domestic violence exists because husbands believe they have an absolute right over the sexuality of their wives. Abusive husbands also abuse their daughters while sons learn violent behavior from their fathers. Crimes must be considered irrespective of whether they are committed outside or inside the home.

2008-01-01

The purpose of this study was to examine the prevalence of potentially inappropriate medication use (PIMs) among community-dwelling older adults and the association between PIMs and health care outcomes. Participants were 17,971 individuals age 65 years and older. PIM use was defined by the Beers criteria. Drug-related problems (DRPs) were defined using ICD-9 codes. Forty percent of the 17,971 individuals filled at least 1 PIM prescription, and 13% filled 2 or more PIM prescriptions. Overall DRP prevalence among those with at least 1 PIM prescription was 14.3% compared to 4.7% in the non-PIM group (p < .001). In conclusion, preventing PIM use may be important for decreasing medication-related problems, which are increasingly being recognized as requiring an integrated interdisciplinary approach.

Sleep problems in children with autism spectrum disorders (ASD) are under-recognized and under-treated. Identifying treatment value accounting for health effects on family members (spillovers) could improve the perceived cost-effectiveness of interventions to improve child sleep habits. A prospective cohort study (N = 224) was conducted with registry and postal survey data completed by the primary caregiver. We calculated quality of life outcomes for the child and the primary caregiver associated with treatments to improve sleep in the child based on prior clinical trials. Predicted treatment effects for melatonin and behavioral interventions were similar in magnitude for the child and for the caregiver. Accounting for caregiver spillover effects associated with treatments for the child with ASD increases treatment benefits and improves cost-effectiveness profiles.

Plastic packaging is essential nowadays. However, the huge environmental problem caused by landfill disposal of non-biodegradable polymers in the end of life has to be minimized and preferentially eliminated. The solution may rely on the use of biopolymers, in particular polysaccharides. These macromolecules with film-forming properties are able to produce attracting biodegradable materials, possibly applicable in food packaging. Despite all advantages of using polysaccharides obtained from different sources, some drawbacks, mostly related to their low resistance to water, mechanical performance and price, have hindered their wider use and commercialization. Nevertheless, with increasing attention and research on this field, it has been possible to trace some strategies to overcome the problems and recognize solutions. This review summarizes some of the most used polysaccharides in food packaging applications. PMID:27089372

The increasing problem of obesity in childhood is recognized as both a short-term and long-term serious public-health concern. Excess body weight may contribute to psychological morbidity; cancers; metabolic, cardiovascular and musculoskeletal disorders; and dermatological conditions. There is increasing recognition of the role of genetic factors in the aetiology of obesity. Although in the vast majority of cases these influences are polygenic, some obese children suffer from monogenic disorders, which may present with obesity alone. However, more often than not, they generally display other syndromic features. Some of these syndromes have a clear cutaneous phenotype, and these conditions will be the focus of this review. © The Author(s) CED © 2012 British Association of Dermatologists.

[Hans Jonas: Nature Conservation, Conservation of Life].

PubMed

Burgui Burgui, Mario

2015-01-01

This article discusses three of the problems that the German philosopher Hans Jonas studied. The first one addresses the need for a specific ethic dedicated to the moral dimension of environmental problems, from a different perspective to the traditional. The second problem is crucial in the discussion on environmental ethics: the value of the nature. Does the nature have an intrinsic value or an instrumental value only (to satisfy the interests of the human being)? The thesis of Jonas, which claimed that nature is a good in itself, were further elaborated here. And the third problem is the derivation of moral norms and the role of man in this ethic that recognizes a good in itself in nature. According to Jonas, the human being is not diminished by recognizing the intrinsic value of nature, since the man's uniqueness and value are unquestionable. From these three central issues, the paper highlights the importance of seeking the links between bioethics and environmental ethics to address the current environmental, social and economic crisis.

Assertiveness.

PubMed

Chambers, David W

2009-01-01

Assertiveness means speaking up for one's interpersonal freedoms or as required by one's role responsibilities to engage others in finding viable, stable solutions. Assertiveness is a learnable skill rather than a personality characteristic. The first step in assertiveness is recognizing the nature of one's problem in order to avoid the objectionable and usually ineffective practice of trying to solve other people's problems. A simple assertive approach is to suggest a solution. A more structured technique involves identifying the behavior that is causing a problem and expressing one's feelings about the problem (I-messages). The most powerful technique combines portions of suggested solutions and I-messages with a clear statement of consequences (DESC scripts). Although there may be a small number of circumstances where they are appropriate, acquiescence (temporarily forgoing one's interpersonal freedoms or role responsibilities) or aggression (insisting on one's own solution to the detriment of others) have several disadvantages. An example of justifiable criticism in the case of recognized gross or continuous faulty work by another dentist is presented.

However, the extreme stressors employed during torture force the brain away from the relatively narrow, adaptive range of function it operates within. Torture degrades signal-to-noise ratios of information yield and increases false positive discovery rates. As a discovery methodology, torture fails basic tests of veridical, reliable and replicable information discovery. Torture fails during interrogation because it is an assault on our core integrated, social, psychological and neural functioning. There is a need for a profound cultural shift regarding torture, recognizing that torture impairs, rather than facilitates, investigations and truth-finding. Rising to this challenge will increase operational effectiveness, eliminate prisoner abuse and torment, and aid veridical and actionable information gathering. Policy regarding prisoner and detainee interrogation need to be refocused as a behavioural and brain sciences problem, and not simply treated as a legal, ethical or philosophical problem. Getting the science, ethics and practice in line is a challenge, but it can and should be done.

[Malignant hyperthermia - problem in dental surgery. An introductory report].

PubMed

Kamińska, Ewa; Janas, Anna; Osica, Piotr

2014-01-01

Malignant hyperthermia is a genetic defect of uncontrolled hypermetabolic skeletal muscle response to anesthetic triggering drugs. Some congenital myopathies are regarded as risk increasing factors. The use of volatile anaesthetics or suxamethonium (succinylcholine) in patients who are predisposed to malignant hyperthermia leads to an increase in Ca2+ release from sarcoplasmic reticulum, which in turn causes a set of biochemical and clinical symptoms, which can be a cause of death, if dantrolene is not administered adequately. The aim of the study was to draw attention to the problem of malignant hyperthermia, which is hardly ever described in Polish literature, and requires the necessity of intensifying the cooperation between the dentist and specialists from other medical fields. The origin of the article was a case of congenital myopathy with recognized malignant hyperthermia in an 18-year-old patient, in whom surgical extraction of teeth was indicated. The course of diagnostics and treatment showed once more that contemporary medicine is in need of holistic approach, and in consequence, promising and effective cooperation of many specialists.

[Internalizing symptoms in depressive adolescents - manifestations and methods of identification in schools].

In order to improve teacher-training programs it is important to analyze the different manifestations of depressive symptoms in adolescent students. This study examined the severity and frequency of internalizing symptoms in adolescents with depressive symptoms and the relationship thereof to an increased risk of suicide. 403 students (212 girls and 191 boys) at Austrian secondary schools aged between 16 and 18 years completed the Reynolds Adolescent Depression Scale-2, the Youth Self-Report, and the Suicide Probability Scale. 35 %, and thus more than one third, of the students with depressive symptoms showed high scores on the internalizing scale while being in the normal range on the externalizing scale. Using regression analysis we found that adolescents with internalizing problems show higher levels of physical complaints, anxiety, and depression. Furthermore, attention problems and thought problems are predictors of depression. In addition to depression, anxiety and thought problems, social problems, and aggressive behavior are predictive of a higher suicide risk. These results are discussed with respect to existing studies concerning how to recognize behavioral problems in school. The integration of these results into teachers' education and training serves to raise their awareness of depressive students with internalizing problems and thus helps them when taking appropriate steps to facilitate treatment.

Using a creativity-focused science program to foster general creativity in young children: A teacher action research study

NASA Astrophysics Data System (ADS)

Gomes, Joan Julieanne Mariani

The importance of thinking and problem-solving skills, and the ability to integrate and analyze information has been recognized and yet may be lacking in schools. Creativity is inherently linked to problem finding, problem solving, and divergent thinking (Arieti, 1976; Csikszentmihalyi, 1990; Milgram, 1990). The importance of early childhood education and its role in the formation of young minds has been recognized (Caine & Caine, 1991; Montessori, 1967a, 1967b; Piaget, 1970). Early childhood education also impacts creativity (Gardner, 1999). The features of brain-based learning (Caine & Caine, 1991; Jensen, 1998; Sousa, 2001; Wolfe, 2001) have a clear connection to nurturing the creative potential in students. Intrinsic motivation and emotions affect student learning and creativity as well (Hennessey & Amabile, 1987). The purpose of this study was to discern if a creativity-focused science curriculum for the kindergarteners at a Montessori early learning center could increase creativity in students. This action research study included observations of the students in two classrooms, one using the creativity-focused science curriculum, and the other using the existing curriculum. The data collected for this interpretive study included interviews with the students, surveys and interviews with their parents and teachers, teacher observations, and the administration of Torrance's (1981) Thinking Creatively in Action and Movement (TCAM) test. The interpretation of the data indicated that the enhanced science curriculum played a role in enhancing the creativity of the children in the creativity-focused group. The results of the TCAM (Torrance, 1981) showed a significant increase in scores for the children in the creativity-focused group. The qualitative data revealed a heightened interest in science and the observation of creative traits, processes, and products in the creativity-focused group children. The implications of this study included the need for meaningful learning experiences, experiential learning opportunities, critical thinking and problem solving activities, and an emphasis on freedom, independence, and autonomy on the part of the learner. These elements, when combined with an integrated science curriculum, can foster creativity in young children.

The Object Oriented Modeling and Design seminar is intended for software professionals and students, it covers the concepts and a language-independent graphical notation that can be used to analyze problem requirements, and design a solution to the problem. The seminar discusses the three kinds of object-oriented models class, state, and interaction. The class model represents the static structure of a system, the state model describes the aspects of a system that change over time as well as control behavior and the interaction model describes how objects collaborate to achieve overall results. Existing knowledge of object oriented programming may benefit the learning of modeling and good design. Specific expectations are: Create a class model, Read, recognize, and describe a class model, Describe association and link, Show abstract classes used with multiple inheritance, Explain metadata, reification and constraints, Group classes into a package, Read, recognize, and describe a state model, Explain states and transitions, Read, recognize, and describe interaction model, Explain Use cases and use case relationships, Show concurrency in activity diagram, Object interactions in sequence diagram.

CONTEMPORARY SITUATIONS AND PROBLEMS OF ROAD/BRIDGE MAINTENANCE TECHNICAL COOPERATION PROJECTS

Nishimiya, Noriaki; Sanui, Kazumasa; Mizota, Yuzo

It is widely acknowledged that roads are the most important transport infrastructure in developing countries. Unlike railroads requiring organizations and systems to operate, individuals can drive on roads. Almost all donors have assisted developing countr ies for new road constructions and rehabilitations. Report of insufficient maintenance in the developing countries, however, has been notable. As a result of the maintenance problems, deterioration of roads is pr ogressing with speed more than expected. It causes the traffic safety problems and an obstacle of economic development. JICA and other donors recognize that this situation can not be overlooked and reci pient countries are increasing their expectation of obtaining assistance on road/bridge maintenance. JICA has implemented over 10 technical cooper ation projects for road/b ridge maintenance in developing countries. JICA conducted a study to review those projects comprehensively. That study aims at obtaining problems, lessons learned and discussion material for policy making and method improvement for future similar pr ojects. This report introduces the outline of the study including additional analysis and recommendations by the authors.

Multicomponent DNA carrier with a vesicular stomatitis virus G-peptide greatly enhances liver-targeted gene expression in mice.

PubMed

Schuster, M J; Wu, G Y; Walton, C M; Wu, C H

1999-01-01

Genes can be targeted to hepatocytes in vitro and in vivo by the use of asialoorosomucoid-polylysine conjugates. After systemic application, this nonviral vector is recognized by highly selective asialoglycoprotein (AsGP) receptors on the sinusoidal liver cell membrane and is taken up via receptor-mediated endocytosis. As most of the DNA is rapidly transferred to lysosomes where it is degraded, transfection efficiency is low and gene expression transient. To address this problem, we incorporated a pH-dependent synthetic hemolytic peptide derived of the G-protein of Vesicular Stomatitis Virus (VSV) into the gene transfer system, to increase endosomal escape of internalized DNA. The multicomponent carrier binds DNA in a nondamaging way, is still recognized by the AsGP receptor, and is targeted to the liver in vivo. Injection of DNA complexes containing a luciferase marker gene resulted in luciferase expression of 29 000 pg/g liver which corresponded to an increase of a factor of 10(3) overexpression after injection of DNA complexes without endosomolytic peptide. Furthermore, the amount of intact transgene within isolated liver cell nuclei was increased by a factor of 10(1)-10(2) by the use of the multicomponent carriers. These results demonstrate that incorporation of a hemolytic peptide into a nonviral vector can greatly increase gene expression while retaining cell type targetability in vivo.

Older adults' recognition of a behavioral health need is one of the strongest predictors of their use of behavioral health services. Thus, study aims were to examine behavioral health problems in a sample of older adults receiving home-based aging services, their recognition of behavioral health problems, and covariates of problem recognition. The study design was cross-sectional. Older adults (n = 141) receiving home-based aging services completed interviews that included: Structured Clinical Interview for DSM-IV; Brief Symptom Inventory-18; attitudinal scales of stigma, expectations regarding aging, and thought suppression; behavioral health treatment experience; and questions about recognition of behavioral health problems. Thirty (21.9%) participants received an Axis I diagnosis (depressive, anxiety, or substance); another 17 (12.1%) were diagnosed with an adjustment disorder. Participants were more likely to recognize having a problem if they had an Axis I diagnosis, more distress on the BSI-18, family member or friend with a behavioral health problem, and greater thought suppression. In logistic regression, participants who identified a family member or friend with a behavioral health problem were more likely to identify having a behavioral health problem themselves. Findings suggest that older adults receiving home-based aging services who recognize behavioral health problems are more likely to have a psychiatric diagnosis or be experiencing significant distress, and they are more familiar with behavioral health problems in others. This familiarity may facilitate treatment planning; thus, older adults with behavioral health problems who do not report familiarity of problems in others likely require additional education.

Trieger, N; Goldblatt, L

The art of history taking involves the ability to recognize the interrelationship between the details of the medical history and the patient's personal history. For the oral surgeon, this provides important insights into how the patient has reacted to illness in the past as well as how he is most likely to react to current treatment. Specific problems have been reviewed as well as suggested interview techniques to guide the oral surgeon in his management of his patient's reactions. No one expects the doctor to be an iconoclast. He cannot be all things to all patients. He should recognize a problem, acknowledge it as a problem, and be flexible enough to deal with it or refer the patient to someone who can. This kind of understanding will enable the oral surgeon to fulfill his role with appreciation from his patients and an inner sense of professional and personal achievement.

Feature extraction and classification algorithms for high dimensional data

NASA Technical Reports Server (NTRS)

Lee, Chulhee; Landgrebe, David

1993-01-01

Feature extraction and classification algorithms for high dimensional data are investigated. Developments with regard to sensors for Earth observation are moving in the direction of providing much higher dimensional multispectral imagery than is now possible. In analyzing such high dimensional data, processing time becomes an important factor. With large increases in dimensionality and the number of classes, processing time will increase significantly. To address this problem, a multistage classification scheme is proposed which reduces the processing time substantially by eliminating unlikely classes from further consideration at each stage. Several truncation criteria are developed and the relationship between thresholds and the error caused by the truncation is investigated. Next an approach to feature extraction for classification is proposed based directly on the decision boundaries. It is shown that all the features needed for classification can be extracted from decision boundaries. A characteristic of the proposed method arises by noting that only a portion of the decision boundary is effective in discriminating between classes, and the concept of the effective decision boundary is introduced. The proposed feature extraction algorithm has several desirable properties: it predicts the minimum number of features necessary to achieve the same classification accuracy as in the original space for a given pattern recognition problem; and it finds the necessary feature vectors. The proposed algorithm does not deteriorate under the circumstances of equal means or equal covariances as some previous algorithms do. In addition, the decision boundary feature extraction algorithm can be used both for parametric and non-parametric classifiers. Finally, some problems encountered in analyzing high dimensional data are studied and possible solutions are proposed. First, the increased importance of the second order statistics in analyzing high dimensional data is recognized. By investigating the characteristics of high dimensional data, the reason why the second order statistics must be taken into account in high dimensional data is suggested. Recognizing the importance of the second order statistics, there is a need to represent the second order statistics. A method to visualize statistics using a color code is proposed. By representing statistics using color coding, one can easily extract and compare the first and the second statistics.

The lung in liver disease: old problem, new concepts.

PubMed

Fallon, Michael B; Zhang, Junlan

2013-01-01

Liver dysfunction has been recognized to influence the lung in many different clinical situations, although the mechanisms for these effects are not well understood. One increasingly recognized interaction, the hepatopulmonary syndrome (HPS) occurs in the context of cirrhosis and results when alveolar microvascular dilation causes arterial gas exchange abnormalities and hypoxemia. HPS occurs in up to 30% of patients with cirrhosis and significantly increases mortality in affected patients. Currently, liver transplantation is the only curative therapy. Experimental biliary cirrhosis induced by common bile duct ligation (CBDL) in the rat reproduces the pulmonary vascular and gas exchange abnormalities of human HPS and has been contrasted with other experimental models of cirrhosis in which HPS does not develop. Microvascular dilation, intravascular monocyte infiltration, and angiogenesis in the lung have been identified as pathologic features that drive gas exchange abnormalities in experimental HPS. Our recent studies have identified biliary epithelium and activation and interaction between the endothelin-1 (ET-1)/endothelial endothelin B (ETB) receptor and CX3CL1/CX3CR1 pathways as important mechanisms for the observed pathologic events. These studies define novel interactions between the lung and liver in cirrhosis and may lead to effective medical therapies.

The use of relaxation-mental imagery (self-hypnosis) in the management of 505 pediatric behavioral encounters.

1984-02-01

This report assessed outcomes of hypnotherapeutic interventions for 505 children and adolescents seen by four pediatricians over a period of one year and followed from four months to two years. Presenting problems included enuresis, acute pain, chronic pain, asthma, habit disorders, obesity, encopresis, and anxiety. Using strict criteria for determination of problem resolution (e.g., all beds dry) and recognizing that some conditions were intrinsically chronic, the authors found that 51% of these children and adolescents achieved complete resolution of the presenting problem; an additional 32% achieved significant improvement, 9% showed initial or some improvement; and 7% demonstrated no apparent change or improvement. Children as young as three years of age effectively applied self-hypnosis techniques. In general, facility in self-hypnosis increased with age. There was an inverse correlation (p less than 0.001) between clinical success and number of visits, suggesting that prediction of responsivity is possible after four visits or less.

Pupillary response to complex interdependent tasks: A cognitive-load theory perspective.

PubMed

Mitra, Ritayan; McNeal, Karen S; Bondell, Howard D

2017-10-01

Pupil dilation is known to indicate cognitive load. In this study, we looked at the average pupillary responses of a cohort of 29 undergraduate students during graphical problem solving. Three questions were asked, based on the same graphical input. The questions were interdependent and comprised multiple steps. We propose a novel way of analyzing pupillometry data for such tasks on the basis of eye fixations, a commonly used eyetracking parameter. We found that pupil diameter increased during the solution process. However, pupil diameter did not always reflect the expected cognitive load. This result was studied within a cognitive-load theory model. Higher-performing students showed evidence of germane load and schema creation, indicating use of the interdependent nature of the tasks to inform their problem-solving process. However, lower-performing students did not recognize the interdependent nature of the tasks and solved each problem independently, which was expressed in a markedly different pupillary response pattern. We discuss the import of our findings for instructional design.

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.

Cybersecurity vulnerabilities in medical devices: a complex environment and multifaceted problem

The increased connectivity to existing computer networks has exposed medical devices to cybersecurity vulnerabilities from which they were previously shielded. For the prevention of cybersecurity incidents, it is important to recognize the complexity of the operational environment as well as to catalog the technical vulnerabilities. Cybersecurity protection is not just a technical issue; it is a richer and more intricate problem to solve. A review of the factors that contribute to such a potentially insecure environment, together with the identification of the vulnerabilities, is important for understanding why these vulnerabilities persist and what the solution space should look like. This multifaceted problem must be viewed from a systemic perspective if adequate protection is to be put in place and patient safety concerns addressed. This requires technical controls, governance, resilience measures, consolidated reporting, context expertise, regulation, and standards. It is evident that a coordinated, proactive approach to address this complex challenge is essential. In the interim, patient safety is under threat. PMID:26229513

Can callous-unemotional traits enhance the understanding, diagnosis, and treatment of serious conduct problems in children and adolescents? A comprehensive review.

PubMed

Frick, Paul J; Ray, James V; Thornton, Laura C; Kahn, Rachel E

2014-01-01

This article provides a comprehensive review of the research on the use of callous and unemotional (CU) traits for designating an important subgroup of children and adolescents with severe conduct problems. It focuses on the etiological significance of recognizing this subgroup of youths with severe conduct problems, its implications for diagnostic classification, and the treatment implications of this research. The review highlights limitations in existing research and provides directions for future research. The available research suggests that children and adolescents with severe conduct problems and elevated CU traits show distinct genetic, cognitive, emotional, biological, environmental, and personality characteristics that seem to implicate different etiological factors underlying their behavior problems relative to other youths with severe conduct problems. Recognizing these subgroups could be critical for guiding future research on the causes of severe conduct problems in children and adolescents. Further, children and adolescents with both severe conduct problems and elevated CU traits appear to be at risk for more severe and persistent antisocial outcomes, even controlling for the severity of their conduct problems, the age of onset of their conduct problems, and common comorbid problems, which supports the clinical importance of designating this group in diagnostic classification systems. Finally, although children and adolescents with both severe conduct problems and elevated CU traits tend to respond less positively to typical interventions provided in mental health and juvenile justice settings, they show positive responses to certain intensive interventions tailored to their unique emotional and cognitive characteristics.

The Science Council of Japan (SCJ) is an academic body that represents Japanese 700,000 scientists. The activity of SCJ is changing rapidly, in which the science associated with society is increasingly important. In this context, the engineering education for ethics is treated at SCJ. The importance of engineering ethics was first recognized at the 5th division of 17th term (1999-2001) of SCJ, in which education for engineering ethics based on the analysis of ethical problems occurred in Japan is recommended and it asked the engineering societies to establish the code of ethics. Following this proposal, SCJ founded a committee to treat the problem at 18th and 19th terms. The committee proposed a procedure to prevent misconduct associated with scientific activities and the importance of education of science and engineering ethics especially for young students at tertiary education.

The counterfeiting of products and financial instruments is a major problem throughout the world today. The dimensions of the problem are growing, accelerated by the expanding availability of production technologies to sophisticated counterfeiters and the increasing capabilities of these technologies. Various optical techniques, including holography, are beingused in efforts to mark authentic products and to distinguish them from copies. Industry is recognizing that the effectiveness of these techniques depends on such factors as the economics of the counterfeiting process and the distribution channels for the products involved, in addition to the performance of the particular optical security technologies used. This paper surveys the nature of the growing counterfeit market place and reviews the utility of holographic optical security systems. In particular, we review the use of holograms on credit cards and other products; and outline certain steps the holography industry should take to promote these application.

Robust wafer identification recognition based on asterisk-shape filter and high-low score comparison method.

PubMed

Hsu, Wei-Chih; Yu, Tsan-Ying; Chen, Kuan-Liang

2009-12-10

Wafer identifications (wafer ID) can be used to identify wafers from each other so that wafer processing can be traced easily. Wafer ID recognition is one of the problems of optical character recognition. The process to recognize wafer IDs is similar to that used in recognizing car license-plate characters. However, due to some unique characteristics, such as the irregular space between two characters and the unsuccessive strokes of wafer ID, it will not get a good result to recognize wafer ID by directly utilizing the approaches used in car license-plate character recognition. Wafer ID scratches are engraved by a laser scribe almost along the following four fixed directions: horizontal, vertical, plus 45 degrees , and minus 45 degrees orientations. The closer to the center line of a wafer ID scratch, the higher the gray level will be. These and other characteristics increase the difficulty to recognize the wafer ID. In this paper a wafer ID recognition scheme based on an asterisk-shape filter and a high-low score comparison method is proposed to cope with the serious influence of uneven luminance and make recognition more efficiently. Our proposed approach consists of some processing stages. Especially in the final recognition stage, a template-matching method combined with stroke analysis is used as a recognizing scheme. This is because wafer IDs are composed of Semiconductor Equipment and Materials International (SEMI) standard Arabic numbers and English alphabets, and thus the template ID images are easy to obtain. Furthermore, compared with the approach that requires prior training, such as a support vector machine, which often needs a large amount of training image samples, no prior training is required for our approach. The testing results show that our proposed scheme can efficiently and correctly segment out and recognize the wafer ID with high performance.

As the authors of the lead paper recognize, networks have become an increasingly popular form of organizing, both in the delivery of public services and within political arenas. A network is an arrangement of individuals and/or organizations that are linked through connections that range from informal relationships to formally agreed protocols. Networks have proved useful in addressing complex and intractable problems that require a holistic approach to identifying and implementing long-term solutions. They succeed in situations where hierarchies and "silo-based" systems have failed, and are particularly valuable in facilitating the transfer of resources and knowledge across sectoral and organizational boundaries.

How not to criticize the precautionary principle.

PubMed

Hughes, Jonathan

2006-10-01

The precautionary principle has its origins in debates about environmental policy, but is increasingly invoked in bioethical contexts. John Harris and Søren Holm argue that the principle should be rejected as incoherent, irrational, and representing a fundamental threat to scientific advance and technological progress. This article argues that while there are problems with standard formulations of the principle, Harris and Holm's rejection of all its forms is mistaken. In particular, they focus on strong versions of the principle and fail to recognize that weaker forms, which may escape their criticisms, are both possible and advocated in the literature.

Process Control in Production-Worthy Plasma Doping Technology

2006-11-13

As the semiconductor industry continues to scale devices of smaller dimensions and improved performance, many ion implantation processes require lower energy and higher doses. Achieving these high doses (in some cases {approx}1x1016 ions/cm2) at low energies (<3 keV) while maintaining throughput is increasingly challenging for traditional beamline implant tools because of space-charge effects that limit achievable beam density at low energies. Plasma doping is recognized as a technology which can overcome this problem. In this paper, we highlight the technology available to achieve process control for all implant parameters associated with modem semiconductor manufacturing.

New Challenges in Information Integration

NASA Astrophysics Data System (ADS)

Haas, Laura M.; Soffer, Aya

Information integration is the cornerstone of modern business informatics. It is a pervasive problem; rarely is a new application built without an initial phase of gathering and integrating information. Information integration comes in a wide variety of forms. Historically, two major approaches were recognized: data federation and data warehousing. Today, we need new approaches, as information integration becomes more dynamic, while coping with growing volumes of increasingly dirty and diverse data. At the same time, information integration must be coupled more tightly with the applications and the analytics that will leverage the integrated results, to make the integration process more tractable and the results more consumable.

Observations on the State of Indigenous Human Rights in Light of the UN Declaration on the Rights of Indigenous Peoples: Morocco

Since the ascent of King Mohammed VI in 1999, Morocco has made strides to recognize the rights of its Amazigh (Berber) population. But the pace of progress is far too slow. One significant problem is the government's unwillingness to recognize the Amazigh as an indigenous people, which in turn undermines the Amazigh's ability to participate in…

Complex Human Activity Recognition Using Smartphone and Wrist-Worn Motion Sensors

Shoaib, Muhammad; Bosch, Stephan; Incel, Ozlem Durmaz; Scholten, Hans; Havinga, Paul J. M.

The position of on-body motion sensors plays an important role in human activity recognition. Most often, mobile phone sensors at the trouser pocket or an equivalent position are used for this purpose. However, this position is not suitable for recognizing activities that involve hand gestures, such as smoking, eating, drinking coffee and giving a talk. To recognize such activities, wrist-worn motion sensors are used. However, these two positions are mainly used in isolation. To use richer context information, we evaluate three motion sensors (accelerometer, gyroscope and linear acceleration sensor) at both wrist and pocket positions. Using three classifiers, we show that the combination of these two positions outperforms the wrist position alone, mainly at smaller segmentation windows. Another problem is that less-repetitive activities, such as smoking, eating, giving a talk and drinking coffee, cannot be recognized easily at smaller segmentation windows unlike repetitive activities, like walking, jogging and biking. For this purpose, we evaluate the effect of seven window sizes (2–30 s) on thirteen activities and show how increasing window size affects these various activities in different ways. We also propose various optimizations to further improve the recognition of these activities. For reproducibility, we make our dataset publicly available. PMID:27023543

A Sharp methodology for VLSI layout

NASA Astrophysics Data System (ADS)

Bapat, Shekhar

1993-01-01

The layout problem for VLSI circuits is recognized as a very difficult problem and has been traditionally decomposed into the several seemingly independent sub-problems of placement, global routing, and detailed routing. Although this structure achieves a reduction in programming complexity, it is also typically accompanied by a reduction in solution quality. Most current placement research recognizes that the separation is artificial, and that the placement and routing problems should be solved ideally in tandem. We propose a new interconnection model, Sharp and an associated partitioning algorithm. The Sharp interconnection model uses a partitioning shape that roughly resembles the musical sharp 'number sign' and makes extensive use of pre-computed rectilinear Steiner trees. The model is designed to generate strategic routing information along with the partitioning results. Additionally, the Sharp model also generates estimates of the routing congestion. We also propose the Sharp layout heuristic that solves the layout problem in its entirety. The Sharp layout heuristic makes extensive use of the Sharp partitioning model. The use of precomputed Steiner tree forms enables the method to model accurately net characteristics. For example, the Steiner tree forms can model both the length of the net and more importantly its route. In fact, the tree forms are also appropriate for modeling the timing delays of nets. The Sharp heuristic works to minimize both the total layout area by minimizing total net length (thus reducing the total wiring area), and the congestion imbalances in the various channels (thus reducing the unused or wasted channel area). Our heuristic uses circuit element movements amongst the different partitioning blocks and selection of alternate minimal Steiner tree forms to achieve this goal. The objective function for the algorithm can be modified readily to include other important circuit constraints like propagation delays. The layout technique first computes a very high-level approximation of the layout solution (i.e., the positions of the circuit elements and the associated net routes). The approximate solution is alternately refined, objective function. The technique creates well defined sub-problems and offers intermediary steps that can be solved in parallel, as well as a parallel mechanism to merge the sub-problem solutions.

To understand treatment preferences and help-seeking behaviors among psychiatric patients for their sleep problems, and to examine determinants of problem recognition and help-seeking among patients with sleep difficulties. A cross-sectional survey was conducted among psychiatric outpatients in Singapore (n=400). Participants completed questionnaires that assessed their sleep quality, daytime fatigue, help-seeking behavior, treatment preferences for sleep problems, and sociodemographic information. Multiple logistic regressions were used to identify correlates of patients who recognized their sleep difficulties and of those who had sought help. Mental health professionals were the most preferred choice (60.8%) for consultation on sleep problems. Among patients with poor sleep quality (n=275), 28.4% denied having any problems and 38.9% had not sought help. Patients with chronic physical comorbidity were less likely to recognize their sleep problems (OR=0.432, p-value=0.009), while those with psychiatric comorbidity were twice as likely to perceive the problems (OR=2.094, p-value=0.021) and to seek help (OR=1.957, p-value=0.022). Daytime fatigue was associated with higher odds of problem recognition (OR=1.106, p-value=0.001) and help-seeking (OR=1.064, p-value=0.016). A considerable number of patients did not perceive their poor sleep as an issue and had not sought help for it. General sleep hygiene education is needed for psychiatric patients.

Song, Tianyan; Duperthuy, Marylise; Wai, Sun Nyunt

2016-01-01

Bacterial biofilm is an emerging clinical problem recognized in the treatment of infectious diseases within the last two decades. The appearance of microbial biofilm in clinical settings is steadily increasing due to several reasons including the increased use of quality of life-improving artificial devices. In contrast to infections caused by planktonic bacteria that respond relatively well to standard antibiotic therapy, biofilm-forming bacteria tend to cause chronic infections whereby infections persist despite seemingly adequate antibiotic therapy. This review briefly describes the responses of biofilm matrix components and biofilm-associated bacteria towards sub-lethal concentrations of antimicrobial agents, which may include the generation of genetic and phenotypic variabilities. Clinical implications of bacterial biofilms in relation to antibiotic treatments are also discussed. PMID:27338489

Nelson, Karl G; Oehlert, Mary E

2008-06-01

Rates of pathological gambling have increased with the availability of legalized gambling. Substance-abuse units increasingly recognize the need to assess for gambling problems. The South Oaks Gambling Screen (SOGS; H. R. Lesieur & S. B. Blume, 1987) has filled this need. Previous research (M. Oehlert & K. Nelson, 2004) has considered the feasibility of reducing the length of the SOGS while maintaining its ability to identify people at risk for problematic gambling. In this study, the authors examined the utility of a shortened SOGS (SSOGS) in a 2nd sample of veterans with addictions. The authors used data analysis to explore SSOGS psychometric properties and to provide additional support for use of the shorter instrument. 2008 APA

Global health priorities – priorities of the wealthy?

2005-01-01

Health has gained importance on the global agenda. It has become recognized in forums where it was once not addressed. In this article three issues are considered: global health policy actors, global health priorities and the means of addressing the identified health priorities. I argue that the arenas for global health policy-making have shifted from the public spheres towards arenas that include the transnational for-profit sector. Global health policy has become increasingly fragmented and verticalized. Infectious diseases have gained ground as global health priorities, while non-communicable diseases and the broader issues of health systems development have been neglected. Approaches to tackling the health problems are increasingly influenced by trade and industrial interests with the emphasis on technological solutions. PMID:15847685

Chloride Permeability of Damaged High-Performance Fiber-Reinforced Cement Composite by Repeated Compressive Loads.

PubMed

Lee, Byung Jae; Hyun, Jung Hwan; Kim, Yun Yong; Shin, Kyung Joon

2014-08-11

The development of cracking in concrete structures leads to significant permeability and to durability problems as a result. Approaches to controlling crack development and crack width in concrete structures have been widely debated. Recently, it was recognized that a high-performance fiber-reinforced cement composite (HPFRCC) provides a possible solution to this inherent problem of cracking by smearing one or several dominant cracks into many distributed microcracks under tensile loading conditions. However, the chloride permeability of HPFRCC under compressive loading conditions is not yet fully understood. Therefore, the goal of the present study is to explore the chloride diffusion characteristics of HPFRCC damaged by compressive loads. The chloride diffusivity of HPFRCC is measured after being subjected to various repeated loads. The results show that the residual axial strain, lateral strain and specific crack area of HPFRCC specimens increase with an increase in the damage induced by repeated loads. However, the chloride diffusion coefficient increases only up to 1.5-times, whereas the specific crack area increases up to 3-times with an increase in damage. Although HPFRCC shows smeared distributed cracks in tensile loads, a significant reduction in the diffusion coefficient of HPFRCC is not obtained compared to plain concrete when the cyclic compressive load is applied below 85% of the strength.

Rural Latino caregivers' beliefs and behaviors around their children's salt consumption.

Hoeft, Kristin S; Guerra, Claudia; Gonzalez-Vargas, M Judy; Barker, Judith C

2015-04-01

Prevalence of high blood pressure has been increasing in U.S. children, with implications for long term health consequences. Sodium consumption, a modifiable risk factor for high blood pressure, is above recommended limits and increasing. Very little is known about Latino caregiver beliefs and behaviors around their children's salt consumption. In California's Central Valley, qualitative interviews in Spanish investigated low-income caregivers' views and understandings of their children's dietary salt consumption. Thirty individual interviews and 5 focus groups were conducted (N=61). Interview transcripts were translated and transcribed, coded and thematically analyzed. Seven primary topic areas around children's salt intake and its impact on health were identified: children's favorite foods, children's dietary salt sources, superiority of home-cooked foods, salty and sweet foods, managing salt for health, developing children's tastes, and adding salt added at the table. Parents recognize common sources of sodium such as "junk food" and processed food and made efforts to limit their children's consumption of these foods, but may overlook other significant sodium sources, particularly bread, cheese, prepared soups and sports drinks. Caregivers recognize excess salt as unhealthy for children, but don't believe health problems (like high blood pressure) can occur in young children. Nevertheless, they made efforts to limit how much salt their children consumed through a variety of strategies; school meals were a source of high sodium that they felt were outside of their control. Latino caregivers are concerned about their children's salt intake and attempt to limit consumption, but some common sources of sodium are under-recognized. Copyright © 2014 Elsevier Ltd.

This paper describes a study addressing the issue of developing an appropriate mapping of knowledge acquisition methods to problem types for intelligent tutoring system development. Recent research has recognized that knowledge acquisition methodologies are not general across problem domains; the effectiveness of a method for obtaining knowledge depends on the characteristics of the domain and problem solving task. Southwest Research Institute developed a taxonomy of problem types by evaluating the characteristics that discriminate between problems and grouping problems that share critical characteristics. Along with the problem taxonomy, heuristics that guide the knowledge acquisition process based on the characteristics of the class are provided.

Chronic obstructive pulmonary disease (COPD) is a very prevalent and invalidating disease. The aim of this study was to analyze the burden borne by informal caregivers of patients with COPD. We used the Survey on Disabilities, Personal Autonomy, and Dependency Situations (Encuesta sobre Discapacidad, Autonomía personal y Situaciones de Dependencia [EDAD]-2008) to obtain information on the characteristics of disabled individuals with COPD and their caregivers in Spain. Additionally, statistical multivariate analyses were performed to analyze the impact that an increase in dependence would have on the problems for which caregivers provide support, in terms of health, professional, and leisure/social dimensions. A total of 461,884 individuals with one or more disabilities and with COPD were identified, and 220,892 informal caregivers were estimated. Results showed that 35% of informal caregivers had health-related problems due to the caregiving provided; 83% had leisure/social-related problems; and among caregivers of working age, 38% recognized having profession-related problems. The probability of a problem arising was significantly associated with the degree of dependence of the patient receiving care. Caregivers of patients with great dependence showed a 39% higher probability of presenting health-related problems, 27% more professional problems, and 23% more leisure problems compared with those with nondependent patients. The results show the large impact on society in terms of the welfare of informal caregivers of patients with COPD. A higher level of dependence was associated with more severe problems in caregivers, in all dimensions.

Thus, it was concluded that the activities and result in studying mathematic increased after applying learning technic the TAPPS.

The medical folder as an active tool in defining the clinical decision-making process.

PubMed

Ferri, F

1995-01-01

Whenever the user of a consultation system needs to know a large amount of information items that are possibly inter-related, a system that is able to cooperate with the user can simplify the interaction and increase its speed. In fact, these systems can recognize the goals of the user, individuate the information related to his goals, and finally focus their attention on this information [1]. This paper describes research work on the design and creation of a medical folder management system capable of establishing cooperative dialogue with users who have access to the information contained therein. Particular attention has thus been paid to the problems of man-computer dialogue and user models. The research work has addressed the problem of integrating into the system knowledge about the medical domain and users (physicians are only used for the time being), which are both necessary to activate a cooperative dialogue. After analysing the literature on the problems of user models, this paper presents and formalizes a study performed at the IVth Surgical Clinic of the Rome University Umberto I General Hospital to identify and represent how, when, and with what goals the physician consults the medical folder, as well as the dialogue procedures he normally adopts. The paper also illustrates important characteristics of the CADMIO prototype, which has been developed since the study was made. CADMIO stores information about users for use in recognizing and interpreting their behaviour, providing help, and in acquiring and returning further information. Whilst always bearing in mind the physician's pre-established goals, it structures information to facilitate his consultation activity, offering him options for the retrieval of further information semantically linked to that already obtained.

Why do DVT and PE remain such a serious problem, particularly given the availability of effective strategies for preventing and treating them? The answer lays primarily in the failure to consistently use evidence-based interventions in high-risk individuals and in the lack of adherence to the different prophylactic interventions. In order to impact the incidence and burden of DVT/PE and increase public awareness, implementation of electronic alerts and evidence-based approaches, and scientific translational research are required. The commitment of all levels of governments as well as public and private institutions will be crucial to reduce the incidence of DVT, a leading cause of death.

Load management is being recognized as an important option for active user participation in the energy market. Traditional load management methods usually require a centralized powerful control center and a two-way communication network between the system operators and energy end-users. The increasing user participation in smart grids may limit their applications. In this paper, a distributed solution for load management in emerging smart grids is proposed. The load management problem is formulated as a constrained optimization problem aiming at maximizing the overall utility of users while meeting the requirement for load reduction requested by the system operator, and is solved by using a distributed dynamic programming algorithm. The algorithm is implemented via a distributed framework and thus can deliver a highly desired distributed solution. It avoids the required use of a centralized coordinator or control center, and can achieve satisfactory outcomes for load management. Simulation results with various test systems demonstrate its effectiveness.

Does Affective Theory of Mind Contribute to Proactive Aggression in Boys with Conduct Problems and Psychopathic Tendencies?

Gillespie, Steven M; Kongerslev, Mickey T; Sharp, Carla; Bo, Sune; Abu-Akel, Ahmad M

2018-04-27

Adolescent psychopathic tendencies are associated with phenotypic increases in proactive aggression. However, the extent to which an understanding of others' affective mental states, or affective theory of mind (ToM), contributes to proactive aggression remains unknown. We examined how performance on a well-known test of affective ToM, based on cropped images of the eye region, contributes to reactive and proactive types of aggression in a mixed ethnicity sample of 80 incarcerated adolescent boys. A hierarchical regression model showed that affective ToM predicted proactive aggression over and above the influence of clinically rated psychopathic tendencies. Importantly, affective ToM was unrelated to reactive aggression. Our results suggest that being able to recognize others' affective mental states may be an important factor in aggressing against others for personal gain. These findings have implications for interventions designed to enhance ToM in youth with conduct problems.

Neighborhood characteristics and mental health among African Americans and whites living in a racially integrated urban community.

Aspects of the environment in which one lives are increasingly being recognized as major contributors to health, yet few empirical studies have focused on mental health. Therefore, we sought to determine if neighborhood characteristics were associated with mental health outcomes among 1408 African-American (59.3%) and white (40.7%) adults living in a socio-economically homogeneous, racially integrated, urban community in Baltimore, MD. Among African Americans and whites, the perception of severe problems in the community was associated with higher levels of stress (approximately 1.8 units higher), anxiety (approximately 1.8 units higher), and depression (OR= approximately 2.0) compared to those who perceived no or few problems (all p<0.05). Community cohesion, the perception that people generally work together, was associated with better mental health among whites only. These findings give further insight into the complex environment of inner-city communities.

Reflections on curative health care in Nicaragua.

PubMed Central

Slater, R G

1989-01-01

Improved health care in Nicaragua is a major priority of the Sandinista revolution; it has been pursued by major reforms of the national health care system, something few developing countries have attempted. In addition to its internationally recognized advances in public health, considerable progress has been made in health care delivery by expanding curative medical services through training more personnel and building more facilities to fulfill a commitment to free universal health coverage. The very uneven quality of medical care is the leading problem facing curative medicine now. Underlying factors include the difficulty of adequately training the greatly increased number of new physicians. Misdiagnosis and mismanagement continue to be major problems. The curative medical system is not well coordinated with the preventive sector. Recent innovations include initiation of a "medicina integral" residency, similar to family practice. Despite its inadequacies and the handicaps of war and poverty, the Nicaraguan curative medical system has made important progress. PMID:2705603

When dogs look back: inhibition of independent problem-solving behaviour in domestic dogs (Canis lupus familiaris) compared with wolves (Canis lupus).

PubMed

Udell, Monique A R

2015-09-01

Domestic dogs have been recognized for their social sensitivity and aptitude in human-guided tasks. For example, prior studies have demonstrated that dogs look to humans when confronted with an unsolvable task; an action often interpreted as soliciting necessary help. Conversely, wolves persist on such tasks. While dogs' 'looking back' behaviour has been used as an example of socio-cognitive advancement, an alternative explanation is that pet dogs show less persistence on independent tasks more generally. In this study, pet dogs, shelter dogs and wolves were given up to three opportunities to open a solvable puzzle box: when subjects were with a neutral human caretaker, alone and when encouraged by the human. Wolves were more persistent and more successful on this task than dogs, with 80% average success rate for wolves versus a 5% average success rate for dogs in both the human-in and alone conditions. Dogs showed increased contact with the puzzle box during the encouragement condition, but only a moderate increase in problem-solving success. Social sensitivity appears to play an important role in pet and shelter dogs' willingness to engage in problem-solving behaviour, which could suggest generalized dependence on, or deference to, human action. © 2015 The Author(s).

Subcutaneous drug infusions: a review of problems and solutions.

Mitten, T

2001-02-01

Subcutaneous drug infusion using a portable syringe driver has had a significant impact on patient comfort in palliative care. It permits the continuous delivery of a range of drug therapies, so bypassing problems of dysphagia, weakness and the inability of many patients in the terminal phase to take oral medication. The devices are not problem-free, however. Mechanical problems, reactions at the infusion site and difficulties with the mixing of drugs in the syringe are all widely recognized. This article reviews some general issues with the operation of portable syringe drivers, and discusses a range of potential problems and their solutions.

Nurses are suffering from increasing stress, and nursing is recognized as one of the most stressful job. Their mental health problems are serious and worthy of attention. The purpose of this study was to explore the relationship between resilience and mental health and general well-being among nurses. A cross-sectional survey was conducted in 2014, using a self-reported questionnaire. Participants were asked to complete the measure of resilience, mental health, and general well-being. The method of randomly cluster sampling was used to select nurses as participants. A survey of 365 nurses was conducted to test the hypothesized model. This study showed that resilience, mental health, and general well-being correlated with each other. General well-being was an effective predictor of resilience and mental health, whereas it both can moderate and mediate the relationship. Strategies to increase nurses' general well-being could enhance their resilience and reduce mental health problems. It is important to improve the mental health of nurses and maintain the professional values that ensure career sustainability. © 2017 John Wiley & Sons Australia, Ltd.

Stress and type 2 diabetes: a review of how stress contributes to the development of type 2 diabetes.

PubMed

Kelly, Shona J; Ismail, Mubarak

2015-03-18

Current policy and research around type 2 diabetes (T2D) interventions largely invoke a behavioral model. We suggest that activation of the physiologic stress response (PSR) from chronic exposure to stressors, low socioeconomic status (SES), severe mental health problems, or aggressive behavior increases the risk of T2D. This article is a comprehensive review of the literature on the link between T2D and psychosocial factors focusing on prospective studies of the risk for developing diabetes. The review found an increased risk for T2D in people: exposed to stressful working conditions or traumatic events; with depression; with personality traits or mental health problems that put them in conflict with others; of low SES, either currently or in childhood; and in racial/ethnic minority populations, independent of current SES. This review suggests that T2D prevention research would be more effective if (a) the PSR to psychosocial factors (especially social disparities) was recognized and (b) intervention programs evaluated reduction in social disparities as part of a comprehensive approach.

Interdisciplinarity, Climate, and Change

2016-12-01

Interdisciplinarity has become synonymous with all things progressive about research and education. This is so not simply because of a philosophical belief in the heterogeneity of knowledge but because of the scientific and social complexities of problems of major concern. The increased demand for improved climate knowledge and information has increased pressure to support planning under changing rates of extremes event occurrence, is well-documented. The application of useful climate data, information and knowledge requires multiple networks and information services infrastructure that support planning and implementation. As widely quoted, Pasteur's quadrant is a label given to a class of scientific research methodologies that seeks fundamental understanding of scientific problems and, simultaneously, to benefit society-what Stokes called "use-inspired research". Innovation, in this context, has been defined as "the process by which individuals and organizations generate new ideas and put them into practice". A growing number of research institutes and programs have begun developing a cadre of professionals focused on integrating basic and applied research in areas such as climate risk assessment and adaptation. There are now several examples of where researchers and teams have crafted examples that include affected communities. In this presentation we will outline the lessons from several efforts including the PACE program, the RISAs, NIDIS, the Climate Services Information System and other interdisciplinary service-oriented efforts in which the author has been involved. Some early lessons include the need to: Recognize that key concerns of social innovation go beyond the projections of climate and other global changes to embrace multiple methods Continue to train scientists of all stripes of disciplinary norms, but higher education should also prepare students who plan to seek careers outside of academia by increasing flexibility in graduate training programs Develop and support boundary institutions that span research, monitoring, prototype development and practice but recognize both the benefits and the limits of co-production Design more comprehensive metrics for evaluation to combat perceptions that interdisciplinary work is only a sideline to a traditional academic career.

Teaching medical professionals and trainees about adolescent suicide prevention: five key problems.

PubMed

Sher, Leo

2012-01-01

Predicting and preventing suicide represent very difficult challenges for clinicians. The awareness of adolescent suicide as a major social and medical problem has increased over the past years. However, many health care professionals who have frequent contact with adolescents are not sufficiently trained in suicide evaluation techniques and approaches to adolescents with suicidal behavior. Suicide prevention efforts among adolescents are restricted by the fact that there are five key problems related to the evaluation and management of suicidality in adolescents: 1. Many clinicians underestimate the importance of the problem of adolescent suicidal behavior and underestimate its prevalence. 2. There is a misconception that direct questioning of adolescents about suicidality is sufficient to evaluate suicide risk. 3. Another misconception is that adolescents with non-psychiatric illnesses do not need to be evaluated for suicidality. 4. Many clinicians do not know about or underestimate the role of contagion in adolescent suicidal behavior. 5. There is a mistaken belief that adolescent males are at lower suicide risk than adolescent females. Educating medical professionals and trainees about the warning signs and symptoms of adolescent suicide and providing them with tools to recognize, evaluate, and manage suicidal patients represent a promising approach to adolescent suicide prevention.

Appreciation of the nature of light demands enhancement over the prevailing scientific epistemology

NASA Astrophysics Data System (ADS)

Roychoudhuri, Chandrasekhar

2011-09-01

Based on attempts to resolve the problem of various self contradictory assumptions behind the prevailing belief on single photon interference, we have analyzed the process steps behind our experimental measurements and named the process as the Interaction Process Mapping Epistemology (IPM-E). This has helped us recognize that the quantum mechanical Measurement Problem has a much universal and deeper root in nature. Our scientific theorization process suffers from a Perpetual Information Challenge (PIC), which cannot be overcome by elegant and/or sophisticated mathematical theories alone. Iterative imaginative application of IPM-E needs to be used as a metaphorical analytical continuation to fill up the missing information gaps. IPM-E has also guided us to recognize the generic NIW-principle (Non-Interaction of Waves) in the linear domain, not explicitly recognized in current books and literature. Superposition effects become manifest through light-matter interactions. Detecting dipoles gets stimulated by multiple superposed beams; it sums the simultaneous multiple stimulations into a single resultant undulation, which then guides the resultant energy exchange. The consequent transformation in the detector corresponds to observed fringes. They neither represent interference of light; nor represent selective arrival or non-arrival of photons on the detector. Photons do not possess any force of mutual interaction to generate their redistribution. Implementation of IPM-E requires us to recognize our subjective interpretation propensity with which we are burdened due to our evolutionary successes.

2013-05-01

Sporeforming bacteria are a significant problem in the food industry as they are ubiquitous in nature and capable of resisting inactivation by heat and chemical treatments designed to inactivate them. Beyond spoilage issues, psychrotolerant sporeformers are becoming increasingly recognized as a potential hazard given the ever-expanding demand for refrigerated processed foods with extended shelf-life. In these products, the sporeforming pathogens of concern are Bacillus cereus, Bacillus weihenstephanensis, and Clostridium botulinum type E. This review article examines the foods, conditions, and organisms responsible for the food safety issue caused by the germination and outgrowth of psychrotolerant sporeforming pathogens in minimally processed refrigerated foods.

Pituitary dysfunction following traumatic brain injury: clinical perspectives

PubMed Central

Tanriverdi, Fatih; Kelestimur, Fahrettin

2015-01-01

Traumatic brain injury (TBI) is a well recognized public health problem worldwide. TBI has previously been considered as a rare cause of hypopituitarism, but an increased prevalence of neuroendocrine dysfunction in patients with TBI has been reported during the last 15 years in most of the retrospective and prospective studies. Based on data in the current literature, approximately 15%–20% of TBI patients develop chronic hypopituitarism, which clearly suggests that TBI-induced hypopituitarism is frequent in contrast with previous assumptions. This review summarizes the current data on TBI-induced hypopituitarism and briefly discusses some clinical perspectives on post-traumatic anterior pituitary hormone deficiency. PMID:26251600

The article presents global data on access to pharmaceuticals and discusses underlying barriers. Two are highly visible: pricing policies and intellectual property rights; two are less recognized: the regulatory environment and scientific and technological capacities. Two ongoing transitions influence and even distort the problem of universal access to medications: the epidemiologic transition to an increasing burden of chronic non-communicable diseases; and the growing role of biotechnology products (especially immunobiologicals) in the pharmacopeia. Examples from Cuba and Brazil are used to explore what can and should be done to address commercial, regulatory, and technological aspects of assuring universal access to medications.

Obesity, defined as a body mass index (BMI) of 30 or higher in adults and BMI in the 95th percentile or higher for children, is epidemic in the United States. The predominant culture of caloric excess and sedentary behaviors contributes to this problem. Obesity increases the risk of many chronic diseases and premature death. The broad response to this costly disease includes efforts from medical providers, local and federal governments, and nongovernmental agencies. Although obesity can be addressed on an individual basis, it is largely recognized as a public health issue. Copyright © 2016 Elsevier Inc. All rights reserved.

Rainwater harvesting, a "soft path" approach toward water management, is increasingly recognized as a key strategy toward ensuring food security and alleviating problems of water scarcity. Interestingly this "modern" approach has been in use for millennia in numerous older civilizations. This article uses India as a case study to explore the social, economic, and environmental dimensions of agricultural rainwater harvesting ponds, and evaluates the viability of these centuries-old systems under current climate and population pressures. A holistic watershed-scale approach that accounts for trade-offs in water availability and socioeconomic wellbeing is recommended for assessing the sustainability of these systems.

Experimenters from the beginning recognized the advantages computers might offer in medical education. Several medical schools have gained experience in such programs in automated instruction. Television images and graphic display combined with computer control and user interaction are effective for teaching problem solving. The National Board of Medical Examiners has developed patient-case simulation for examining clinical skills, and the National Library of Medicine has experimented with combining media. Advances from the field of artificial intelligence and the availability of increasingly powerful microcomputers at lower cost will aid further development. Computers will likely affect existing educational methods, adding new capabilities to laboratory exercises, to self-assessment and to continuing education. PMID:3544511

Violence in the Emergency Department: A Global Problem.

Violence against health care workers is an unfortunately common event. Because of several inherent factors, emergency departments are particularly vulnerable. Once an incident occurs, it often goes unreported and leads to both physical and mental trauma. Health care workers should learn to recognize the cues that patients are escalating toward violence and be familiar with various options for sedating agitated patients. If sedation is not successful, physical restraint may become necessary. There are measures that can be taken that may help minimize the likelihood of violence toward health care workers. These measures include legislation, physical design, and increased security. Copyright © 2017 Elsevier Inc. All rights reserved.

Widespread media publicity has resulted in increased case findings of eating disorders such as anorexia nervosa and bulimia. The etiology of these conditions is complex and multifactorial, and they may have devastating effects on physical and psychological health. Family physicians have an important role to play in recognizing, evaluating and managing eating disorders. Severe anorexics—those who have lost 25% or more of the average weight for their age and height—require specialist management, but milder forms respond to treatment which can be undertaken by an interested family physician. Most cases of uncomplicated bulimia can be treated successfully in a family practice setting. PMID:21278973

What is common among electronic structure calculation, design of MEMS devices, vibrational analysis of high speed railways, and simulation of the electromagnetic field of a particle accelerator? The answer: they all require solving large scale nonlinear eigenvalue problems. In fact, these are just a handful of examples in which solving nonlinear eigenvalue problems accurately and efficiently is becoming increasingly important. Recognizing the importance of this class of problems, an invited minisymposium dedicated to nonlinear eigenvalue problems was held at the 2005 SIAM Annual Meeting. The purpose of the minisymposium was to bring together numerical analysts and application scientists to showcasemore » some of the cutting edge results from both communities and to discuss the challenges they are still facing. The minisymposium consisted of eight talks divided into two sessions. The first three talks focused on a type of nonlinear eigenvalue problem arising from electronic structure calculations. In this type of problem, the matrix Hamiltonian H depends, in a non-trivial way, on the set of eigenvectors X to be computed. The invariant subspace spanned by these eigenvectors also minimizes a total energy function that is highly nonlinear with respect to X on a manifold defined by a set of orthonormality constraints. In other applications, the nonlinearity of the matrix eigenvalue problem is restricted to the dependency of the matrix on the eigenvalues to be computed. These problems are often called polynomial or rational eigenvalue problems In the second session, Christian Mehl from Technical University of Berlin described numerical techniques for solving a special type of polynomial eigenvalue problem arising from vibration analysis of rail tracks excited by high-speed trains.« less

An Overview of Links Between Obesity and Mental Health.

2015-09-01

The American Medical Association recently recognized obesity as both an illness and a leading cause of preventable death and chronic disease. This association is not only linked to physical health outcomes, however, as obesity has also been extensively associated with mental illness as well. Both obesity and severe mental illness decrease quality of life and are associated with an increase in disability, morbidity, and mortality, and when they occur together, these adverse health outcomes are magnified. Despite educational campaigns, increased awareness, and improved treatment options, the high prevalence of mental illness and comorbid obesity remains a serious problem. This review examines this overlap, highlighting clinical and biological factors that have been linked to this association in order to improve our understanding and help elucidate potential therapeutic avenues.

Land drainage is recognized as an integral part of agricultural activity throughout the world. However, the increase in agricultural production has resulted in the loss of wetland functions and values. Therefore, wetland management and agricultural drainage illustrate the conflict between economic development and natural values. This research assesses the approval process for agricultural land drainage in Ontario, Canada, to determine how the benefits of increased agricultural production are balanced against the loss of wetland values. A permit review of drainage applications was conducted from 1978 to 1997 in Zorra Township, Ontario, Canada. Data collection also included the document reviews, interviews with government agencies and wetland evaluation files. The selected criteria include efficiency, equity, consistency and adequacy. The results indicate that while the process is efficient, fundamental problems remain with the bargaining process.

2007-01-01

The authors assessed the risk for psychosocial maladjustment in a population-based sample of dependent children of parents with serious physical illness. In the context of The Hamburg Health Survey, a wide range of data on current life situation and health status was collected from a representative sample of families with children and adolescents between 4 and 18 years old (N=1,950). For 4- to 18-year-old children and adolescents in Germany, the prevalence of a serious physical illness in a parent was 4.1%. The adjusted risk of psychosocial maladjustment in this target group, depending on the case definition, is elevated, with internalizing problems being more prevalent than externalizing problems. Although problems for affected boys decline with puberty, they increase for girls. In this age-group, girls and boys appear to be under particular strain when the respective same-sex parent has a serious physical illness. Exposure to serious parental physical illness is an epidemiologically relevant risk factor for psychosocial maladjustment in children and adolescents that needs to be better recognized by medical professionals.

Child sex trafficking and commercial sexual exploitation of children (CSEC) are major public health problems in the United States and throughout the world. Despite large numbers of American and foreign youth affected and a plethora of serious physical and mental health problems associated with CSEC, there is limited information available to pediatricians regarding the nature and scope of human trafficking and how pediatricians and other health care providers may help protect children. Knowledge of risk factors, recruitment practices, possible indicators of CSEC, and common medical and behavioral health problems experienced by victims will help pediatricians recognize potential victims and respond appropriately. As health care providers, educators, and leaders in child advocacy, pediatricians play an essential role in addressing the public health issues faced by child victims of CSEC. Their roles can include working to increase recognition of CSEC, providing direct care and anticipatory guidance related to CSEC, engaging in collaborative efforts with medical and nonmedical colleagues to provide for the complex needs of youth, and educating child-serving professionals and the public.

2012-02-01

Integration is widely used in physics in electricity and magnetism (E&M), as well as in mechanics, to calculate physical quantities from other non-constant quantities. We designed a survey to assess students' ability to apply integration to physics problems in introductory physics. Each student was given a set of eight problems, and each set of problems had two different versions; one consisted of symbolic problems and the other graphical problems. The purpose of this study was to investigate students' strategies for solving physics problems that use integrals in first and second-semester calculus-based physics. Our results indicate that most students had difficulty even recognizing that an integral is needed to solve the problem.

Orangutans (Pongo spp.) may prefer tools with rigid properties to flimsy tools.

PubMed

Walkup, Kristina R; Shumaker, Robert W; Pruetz, Jill D

2010-11-01

Preference for tools with either rigid or flexible properties was explored in orangutans (Pongo spp.) through an extension of D. J. Povinelli, J. E. Reaux, and L. A. Theall's (2000) flimsy-tool problem. Three captive orangutans were presented with three unfamiliar pairs of tools to solve a novel problem. Although each orangutan has spontaneously used tools in the past, the tools presented in this study were novel to the apes. Each pair of tools contained one tool with rigid properties (functional) and one tool with flimsy properties (nonfunctional). Solving the problem required selection of a rigid tool to retrieve a food reward. The functional tool was selected in nearly all trials. Moreover, two of the orangutans demonstrated this within the first test trials with each of the three tool types. Although further research is required to test this statistically, it suggests either a preexisting preference for rigid tools or comprehension of the relevant features required in a tool to solve the task. The results of this study demonstrate that orangutans can recognize, or learn to recognize, relevant tool properties and can choose an appropriate tool to solve a problem.

Critical materialism: science, technology, and environmental sustainability.

PubMed

York, Richard; Clark, Brett

2010-01-01

There are widely divergent views on how science and technology are connected to environmental problems. A view commonly held among natural scientists and policy makers is that environmental problems are primarily technical problems that can be solved via the development and implementation of technological innovations. This technologically optimistic view tends to ignore power relationships in society and the political-economic order that drives environmental degradation. An opposed view, common among postmodernist and poststructuralist scholars, is that the emergence of the scientific worldview is one of the fundamental causes of human oppression. This postmodernist view rejects scientific epistemology and often is associated with an anti-realist stance, which ultimately serves to deny the reality of environmental problems, thus (unintentionally) abetting right-wing efforts to scuttle environmental protection. We argue that both the technologically optimistic and the postmodernist views are misguided, and both undermine our ability to address environmental crises. We advocate the adoption of a critical materialist stance, which recognizes the importance of natural science for helping us to understand the world while also recognizing the social embeddedness of the scientific establishment and the need to challenge the manipulation of science by the elite.

ROLE OF SYMPATHETIC NERVOUS SYSTEM IN OBESITY RELATED HYPERTENSION

PubMed Central

da Silva, Alexandre; doCarmo, Jussara; Dubinion, John; Hall, John E.

2010-01-01

Obesity is recognized as a major, worldwide, health problem. Excess weight is a major cause of increased blood pressure in most patients with essential hypertension, and greatly increases the risk for diabetes, cardiovascular diseases, and end stage renal disease. Although the mechanisms by which obesity raises blood pressure are not completely understood, increased renal sodium reabsorption, impaired pressure natriuresis, and volume expansion appear to play important roles. Several potential mechanisms have been suggested to contribute to altered kidney function and hypertension in obesity, including activation of the sympathetic nervous system (SNS) and the renin-angiotensin-aldosterone system (RAAS), and physical compression of the kidneys, especially when visceral obesity is present. Activation of the SNS in obesity may be due, in part, to hyperleptinemia and other factors secreted by adipocytes and the gastrointestinal tract, activation of the central nervous melanocortin pathway, and baroreceptor dysfunction.

Rural Latino caregivers’ beliefs and behaviors around their children’s salt consumption

PubMed Central

Hoeft, Kristin S.; Guerra, Claudia; Gonzalez-Vargas, M. Judy; Barker, Judith C.

2015-01-01

Background Prevalence of high blood pressure has been increasing in U.S. children, with implications for long term health consequences. Sodium consumption, a modifiable risk factor for high blood pressure, is above recommended limits and increasing. Very little is known about Latino caregiver beliefs and behaviors around their children’s salt consumption. Methods In California’s Central Valley, qualitative interviews in Spanish investigated low-income caregivers’ views and understandings of their children’s dietary salt consumption. Thirty individual interviews and 5 focus groups were conducted (N=61). Interview transcripts were translated and transcribed, coded and thematically analyzed. Results Seven primary topic areas around children’s salt intake and its impact on health were identified: children’s favorite foods, children’s dietary salt sources, superiority of home-cooked foods, salty and sweet foods, managing salt for health, developing children’s tastes, and adding salt added at the table. Parents recognize common sources of sodium such as “junk food” and processed food and made efforts to limit their children’s consumption of these foods, but may overlook other significant sodium sources, particularly bread, cheese, prepared soups and sports drinks. Caregivers recognize excess salt as unhealthy for children, but don’t believe health problems (like high blood pressure) can occur in young children. Nevertheless, they made efforts to limit how much salt their children consumed through a variety of strategies; school meals were a source of high sodium that they felt were outside of their control. Conclusion Latino caregivers are concerned about their children’s salt intake and attempt to limit consumption, but some common sources of sodium are under-recognized. PMID:25481770

Pediatric Residency Education and the Behavioral and Mental Health Crisis: A Call to Action.

PubMed

McMillan, Julia A; Land, Marshall; Leslie, Laurel K

2017-01-01

For at least 4 decades, the need for improved pediatric residency training in behavioral and mental health has been recognized. The prevalence of behavioral and mental health conditions in children, adolescents, and young adults has increased during that period. However, as recently as 2013, 65% of pediatricians surveyed by the American Academy of Pediatrics indicated that they lacked training in recognizing and treating mental health problems. Current pediatric residency training requirements do not stipulate curricular elements or assessment requirements in behavioral and mental health, and fewer than half of pediatric residents surveyed felt that their competence in dealing with mental health problems was good to excellent. It is time that pediatric residency programs develop the capacity to prepare their residents to meet the behavioral and mental health needs of their patients. Meeting this challenge will require a robust curriculum and effective assessment tools. Ideal training environments will include primary care ambulatory sites that encourage residents to work longitudinally in partnership with general pediatricians and behavioral and mental health trainees and providers; behavioral and mental health training must be integrated into both ambulatory and inpatient experiences. Faculty development will be needed, and in most programs it will be necessary to include nonpediatrician mental health providers to enhance pediatrician faculty expertise. The American Board of Pediatrics intends to partner with other organizations to ensure that pediatric trainees develop the competence needed to meet the behavioral and mental health needs of their patients.

de-Sola, José; Talledo, Hernán; Rodríguez de Fonseca, Fernando; Rubio, Gabriel

2017-01-01

Problematic cell phone use has alarmingly increased in industrialized countries in the past 10 years. For many perpetrators, it can turn into a behavioural addiction, although this is not a recognized medical condition. Although there are many tools for evaluating this use, one of the most widely used tools is the Mobile Phone Problematic Use Scale (MPPUS), which we test on a representative sample of the population in Spain to obtain an estimate of the prevalence of problematic cell phone use in our midst. The age range consists of 16-65 years, with 1,126 surveys conducted. In this population, we verify that the reliability and internal consistency of the MPPUS (α = 0.939) are maintained. Additionally, the construct validity, considering the derived factors (Abuse and Dependence, Craving and Loss of Control, and Dependence on the Social Environment) are aligned with other research and with diverse external criteria of addiction. We establish four categories of users (Casual, Regular, At Risk, and Problematic) and obtain a prevalence of 15.4% among At Risk Users and 5.1% among Problematic Users. This finding implies a total of 20.5% of Users with Problems. A binary logistic regression analysis shows that age, gender, level of education, and daily cell phone use predict problematic cell phone use. The results, based on multiple criteria, show that such problematic use shares features of recognized addictions, affecting large segments of the population and not only adolescents.

2017-06-01

Foot disease is highly prevalent in people with inflammatory arthritis and is often under-recognized. Podiatry intervention can significantly reduce foot pain and disability, with timely access being the key factor. The aim of this study was to plan and implement a quality improvement project to identify the barriers to, and improve, uptake of podiatry services among patients with inflammatory arthritis-related foot problems seen at a tertiary hospital in Singapore. A 6-month quality improvement program was conducted by a team of key stakeholders using quality improvement tools to identify, implement and test several interventions designed to improve uptake of podiatry services. The number of patients referred for podiatry assessment was recorded on a weekly basis by an experienced podiatrist. The criterion for appropriate referral to podiatry was those patients with current or previous foot problems such as foot pain, swelling and deformity. Interventions included education initiatives, revised workflow, development of national guidelines for inflammatory arthritis, local podiatry guidelines for the management of foot and ankle problems, routine use of outcome measures, and introduction of a fully integrated rheumatology-podiatry service with reduced cost package. Referral rates increased from 8% to 11%, and were sustained beyond the study period. Complete incorporation of podiatry into the rheumatology consultation as part of the multidisciplinary team package further increased referrals to achieve the target of full uptake of the podiatry service. Through a structured quality improvement program, referrals to podiatry increased and improved the uptake and acceptance of rheumatology-podiatry services. Copyright © 2016 Elsevier Ltd.

New insights into insight: Neurophysiological correlates of the difference between the intrinsic "aha" and the extrinsic "oh yes" moment.

PubMed

Rothmaler, Katrin; Nigbur, Roland; Ivanova, Galina

2017-01-27

Insight refers to a situation in which a problem solver immediately changes his understanding of a problem situation. This representational change can either be triggered by external stimuli, like a hint or the solution itself, or by internal solution attempts. In the present paper, the differences and similarities between these two phenomena, namely "extrinsic" and "intrinsic" insight, are examined. To this end, electroencephalogram (EEG) is recorded while subjects either recognize or generate solutions to German verbal compound remote associate problems (CRA). Based on previous studies, we compare the alpha power prior to insightful solution recognition with the alpha power prior to insightful solution generation. Results show that intrinsic insights are preceded by an increase in alpha power at right parietal electrodes, while extrinsic insights are preceded by a respective decrease. These results can be interpreted in two ways. In consistency with other studies, the increase in alpha power before intrinsic insights can be interpreted as an increased internal focus of attention. Accordingly, the decrease in alpha power before extrinsic insights may be associated with a more externally oriented focus of attention. Alternatively, the increase in alpha power prior to intrinsic insights can be interpreted as an active inhibition of solution-related information, while the alpha power decrease prior to extrinsic insights may reflect its activation. Regardless of the interpretation, the results provide strong evidence that extrinsic and intrinsic insight differ on the behavioral as well as the neurophysiological level.

Epidemiology and clinical impact of major comorbidities in patients with COPD

PubMed Central

Smith, Miranda Caroline; Wrobel, Jeremy P

2014-01-01

Comorbidities are frequent in chronic obstructive pulmonary disease (COPD) and significantly impact on patients’ quality of life, exacerbation frequency, and survival. There is increasing evidence that certain diseases occur in greater frequency amongst patients with COPD than in the general population, and that these comorbidities significantly impact on patient outcomes. Although the mechanisms are yet to be defined, many comorbidities likely result from the chronic inflammatory state that is present in COPD. Common problems in the clinical management of COPD include recognizing new comorbidities, determining the impact of comorbidities on patient symptoms, the concurrent treatment of COPD and comorbidities, and accurate prognostication. The majority of comorbidities in COPD should be treated according to usual practice, and specific COPD management is infrequently altered by the presence of comorbidities. Unfortunately, comorbidities are often under-recognized and under-treated. This review focuses on the epidemiology of ten major comorbidities in patients with COPD. Further, we emphasize the clinical impact upon prognosis and management considerations. This review will highlight the importance of comorbidity identification and management in the practice of caring for patients with COPD. PMID:25210449

The composite classification problem in optical information processing

NASA Technical Reports Server (NTRS)

Hall, Eric B.

1995-01-01

Optical pattern recognition allows objects to be recognized from their images and permits their positional parameters to be estimated accurately in real time. The guiding principle behind optical pattern recognition is that a lens focusing a beam of coherent light modulated with an image produces the two-dimensinal Fourier transform of that image. When the resulting output is further transformed by the matched filter corresponding to the original image, one obtains the autocorrelation function of the original image, which has a peak at the origin. Such a device is called an optical correlator and may be used to recognize the locate the image for which it is designed. (From a practical perspective, an approximation to the matched filter must be used since the spatial light modulator (SLM) on which the filter is implemented usually does not allow one to independently control both the magnitude and phase of the filter.) Generally, one is not just concerned with recognizing a single image but is interested in recognizing a variety of rotated and scaled views of a particular image. In order to recognize these different views using an optical correlator, one may select a subset of these views (whose elements are called training images) and then use a composite filter that is designed to produce a correlation peak for each training image. Presumably, these peaks should be sharp and easily distinguishable from the surrounding correlation plane values. In this report we consider two areas of research regarding composite optical correlators. First, we consider the question of how best to choose the training images that are used to design the composite filter. With regard to quantity, the number of training images should be large enough to adequately represent all possible views of the targeted object yet small enough to ensure that the resolution of the filter is not exhausted. As for the images themselves, they should be distinct enough to avoid numerical difficulties yet similar enough to avoid gaps in which certain views of the target will be unrecognized. One method that we introduce to study this problem is called probing and involves the creation of the artificial imagery. The second problem we consider involves the clasification of the composite filter's correlation plane data. In particular, we would like to determine not only whether or not we are viewing a training image, but, in the former case, we would like to determine which training image is being viewed. This second problem is investigated using traditional M-ary hypothesis testing techniques.

Sleep problems are known to be risk factors for subsequent emotional and behavioral difficulties in childhood and adolescence. To date, there has been no study investigating the relationships between sleep habits and behavioral problems in a large nonclinical sample of preschool age children. The aim of this study was to examine these relationships and factors associated with the sleep habits of preschool age (2 to 5 year old) children. Their mothers (n = 1,746) completed a multiple-choice questionnaire about the sleep habits and behavior problems of their children, as well as their own sleep habits and working hours at Tokyo metropolitan public nursery schools. The short sleep duration group showed significantly higher aggressive scores than the long sleep duration group among 2- to 3-year-old children, and the irregular bedtime group showed significantly higher aggressive and attention problem scores than the regular bedtime group among 4- to 5-year-old children. Univariate and multivariate logistic regression analyses revealed that children's late bedtime was associated with their mother's late waking-up time, and late schedule of both the mother's leaving and returning home. This study recognized an association between behavioral problems and poor sleep habits among preschool-age children. It is important for children to sleep regularly and adequately in order to decrease their behavior problems. In conclusion, appropriate management of children's sleep by their mothers is necessary for promoting sleep-related health of children.

Human-activity recognition is one of the most challenging problems in computer vision. Researchers from around the world have tried to solve this problem and have come a long way in recognizing simple motions and atomic activities. As the computer vision community heads toward fully recognizing human activities, a challenging and labeled dataset is needed. To respond to that need, we collected a dataset of realistic scenarios in a multi-camera network environment (VideoWeb) involving multiple persons performing dozens of different repetitive and non-repetitive activities. This chapter describes the details of the dataset. We believe that this VideoWeb Activities dataset is unique and it is one of the most challenging datasets available today. The dataset is publicly available online at http://vwdata.ee.ucr.edu/ along with the data annotation.

A guide to wound managment in palliative care.

PubMed

Naylor, Wayne A

2005-11-01

Wound management in palliative patients is often a very challenging area of care. There are many unique issues that can combine to produce complicated wound management scenarios, including the types of wounds and wound symptoms most commonly affecting palliative care patients, as well as the presence of concurrent disease and associated treatment. Problems exist with the availability of suitable dressings and balancing life expectancy with the goals of wound care. A significant, and possibly under-recognized, issue is the emotional and social distress experienced by these patients, which can be directly attributed to their wound. These problems must all be recognized and addressed in order to manage wounds effectively in this patient population. This article aims to explore these issues and offer advice on the management of wound-related symptoms, with the ultimate goal of improving patients' quality of life.

ADHD problem recognition serves as the first step of help seeking for ethnic minority families, such as Latinos, who underutilize ADHD services. The current mixed-method study explores underlying factors influencing recognition of ADHD problems in a sample of 159 school-aged youth. Parent-teacher informant discrepancy results suggest that parent ethnicity, problem domain, and child age influence ADHD problem recognition. Emerging themes from semi-structured qualitative interviews/focus groups conducted with eighteen Spanish-speaking Latino parents receiving school-based services for attention and behavior concerns support a range of recognized ADHD problems, beliefs about causes, and reactions to ADHD identification. Findings provide recommendations for reducing disparities in ADHD problem recognition and subsequent help seeking.

Rapid economic development in China has produced serious ecological, environmental, and health problems. Neurotoxicity has been recognized as a major public health problem. The Chinese government, research institutes, and scientists conducted extensive studies concerning the source, characteristics, and mechanisms of neurotoxicants. This paper presents, for the first time, a comprehensive history and review of major sources of neurotoxicants, national bodies/legislation engaged, and major neurotoxicology research in China. Peer-reviewed research and pollution studies by Chinese scientists from 1991 to 2015 were examined. PubMed, Web of Science and Chinese National Knowledge Infrastructure (CNKI) were the major search tools. The central problem is an increased exposure to neurotoxicants from air and water, food contamination, e-waste recycling, and manufacturing of household products. China formulated an institutional framework and standards system for management of major neurotoxicants. Basic and applied research was initiated, and international cooperation was achieved. The annual number of peer-reviewed neurotoxicology papers from Chinese authors increased almost 30-fold since 2001. Despite extensive efforts, neurotoxicity remains a significant public health problem. This provides great challenges and opportunities. We identified 10 significant areas that require major educational, environmental, governmental, and research efforts, as well as attention to public awareness. For example, there is a need to increase efforts to utilize new in vivo and in vitro models, determine the potential neurotoxicity and mechanisms involved in newly emerging pollutants, and examine the effects and mechanisms of mixtures. In the future, we anticipate working with scientists worldwide to accomplish these goals and eliminate, prevent and treat neurotoxicity. Cai T, Luo W, Ruan D, Wu YJ, Fox DA, Chen J. 2016.

American Indians and Alaska Natives have the nation's highest morbidity and mortality owing to alcohol but also have opportunities to employ policies that could reduce the harmful effects of drinking. As sovereign nations, federally recognized tribes can adopt policies that are highly likely to have a beneficial impact on alcohol problems. The most recently published nationwide research on American Indian alcohol policies (conducted some 30 years ago) suggested that tribal policies may help minimize adverse consequences related to drinking. However, much has changed in Indian country during the last few decades, including redefinitions of relationships among tribes, states, and the federal government; recognition of tribes not previously acknowledged by federal authorities; and the advent of gaming and casinos. These developments raise numerous questions regarding the adoption and implementation of policies pertaining to alcohol. This project used the Federal Register to catalog alcohol statutes adopted by the 334 federally recognized tribes in the lower 48 states between 1975 and 2006. Tribes that do not have an alcohol policy have, by default, retained federal prohibition. During the 30-year study period, the percentage of tribes with statutes that permit alcohol increased from 29.2% to 63.5%. Later policies showed increases in complexity, such as tribal licensing requirements and facility restrictions to accompany increases in gaming and tourism. These data are highly relevant to Native decision makers as they attempt to develop and implement policies that will minimize the harmful effects of alcohol among indigenous peoples.

Effects of subliminal hints on insight problem solving.

Two experiments tested a total of 509 participants on insight problems (the radiation problem and the nine-dot problem). Half of the participants were first exposed to a 1-min movie that included a subliminal hint. The hint raised the solution rate of people who did not recognize it. In addition, the way they solved the problem was affected by the hint. In Experiment 3, a novel technique was introduced to address some methodological concerns raised by Experiments 1 and 2. A total of 80 participants solved the 10-coin problem, and half of them were exposed to a subliminal hint. The hint facilitated solving the problem, and it shortened the solution time. Some implications of subliminal priming for research on and theorizing about insight problem solving are discussed.

Combating desertification in Iran over the last 50 years: an overview of changing approaches.

PubMed

Amiraslani, Farshad; Dragovich, Deirdre

2011-01-01

Desertification in Iran was recognized between the 1930s and 1960s. This paper traces Iran's attempts to reclaim desertified areas, evaluates the anti-desertification approaches adopted, and identifies continuing challenges. Iran has areas vulnerable to desertification due to extensive areas of drylands and increasing population pressure on land and water resources. Over-grazing of rangelands is a particular problem. Initially desertification was combated mainly at the local level and involved dune stabilization measures, especially the use of oil mulch, re-vegetation and windbreaks. Insufficient technical planning in the early years has led to changed approaches to plant densities and species diversity in plantations, and increased on-going management of existing plantations. Since the late 1980s forage and crop production has increased in areas where runoff control techniques are practiced. The social and economic aspects of anti-desertification programs have assisted in poverty reduction by providing off-season employment in rural areas. In 2004 a national plan to combat desertification was ratified and this placed an emphasis on community participation. Continuing challenges include managing existing desertified areas as well as taking into account potential future problems associated with rapidly depleting groundwater supplies and a predicted reduction in the plant growth period accompanying climate change.

Public health readiness has increased at all jurisdictional levels because of increased sensitivity to threats. Since 2001, with billions of dollars invested to bolster the public health system’s capacity, the public expects that public health will identify the etiology of and respond to events more rapidly. However, when etiologies are unknown at the onset of the investigation but interventions must be implemented, public health practitioners must benefit from past investigations’ lessons to strengthen preparedness for emerging threats. We have identified such potentially actionable lessons learned from historically important public health events that occurred primarily as syndromes for which the etiological agent initially was unknown. Ongoing analysis of investigations can advance our capability to recognize and investigate syndromes and other problems and implement the most appropriate interventions. PMID:22571706

Organs donated from persons born outside Spain are becoming increasingly numerous. These persons now account for 26.1% of all donors in the "Malaga sector," an area of tourism with a high percentage of immigrants. Acceptance to donation among persons from Europe and South America is similar to that of Spanish persons but lower among those born in Africa. We must recognize the great help that cultural mediators provided not only by assistance with the language barrier but also by generating confidence among families and understanding their emotions, feelings, and traditions, mainly during interviews with families from different social and cultural miliere. To be efficient, the interpreters or cultural mediators need to have received specific training in the organ donation process and to be involved and convinced that organ donation and transplantation is the best solution for severe health problems.

Coeliac disease: to biopsy or not?

Reilly, Norelle R; Husby, Steffen; Sanders, David S; Green, Peter H R

2018-01-01

Coeliac disease is increasingly recognized as a global problem in both children and adults. Traditionally, the findings of characteristic changes of villous atrophy and increased intraepithelial lymphocytosis identified in duodenal biopsy samples taken during upper gastrointestinal endoscopy have been required for diagnosis. Although biopsies remain advised as necessary for the diagnosis of coeliac disease in adults, European guidelines for children provide a biopsy-sparing diagnostic pathway. This approach has been enabled by the high specificity and sensitivity of serological testing. However, these guidelines are not universally accepted. In this Perspective, we discuss the pros and cons of a biopsy-avoiding pathway for the diagnosis of coeliac disease, especially in this current era of the call for more biopsies, even from the duodenal bulb, in the diagnosis of coeliac disease. In addition, a contrast between paediatric and adult guidelines is presented.

Gastrointestinal and nutritional problems in neurologically impaired children.

PubMed

Quitadamo, Paolo; Thapar, Nikhil; Staiano, Annamaria; Borrelli, Osvaldo

2016-11-01

The current increasing survival of children with severe central nervous system damage has created a major challenge for medical care. Gastrointestinal and nutritional problems in neurologically impaired children have been recently recognized as an integral part of their disease, often leading to growth failure and worsened quality of life for both children and caregivers. Nutritional support is essential for the optimal care of these children. Undernourished handicapped children might not respond properly to intercurrent diseases and suffer unnecessarily. On the other hand, restoring a normal nutritional status results in a better quality of life in many. The easiest and least invasive method to increase energy intake is to improve oral intake. However, oral intake can be maintained as long as there is no risk of aspiration, the child is growing well and the time required to feed the child remains within acceptable limits. When oral intake is unsafe, insufficient or too time consuming, enteral nutrition should be initiated. Damage to the developing central nervous system may result in significant dysfunction in the gastrointestinal tract and is reflected in impairment in oral-motor function, rumination, gastro-oesophageal reflux (GER), with or without aspiration, delayed gastric emptying and constipation. These problems can all potentially contribute to feeding difficulty in disabled children, carrying further challenging long-term management issues.

2017-01-01

Mental health issues have been increasingly recognized as public health problems globally. Their burden is projected to increase over the next several decades. Additional therapies for mental problems are in urgent need worldwide due to the limitations and costs of existing healthcare approaches. Essential oil aromatherapy can provide a cost‐effective and safe treatment for many mental problems. This pilot study observed the effects of bergamot essential oil inhalation on mental health and well‐being, as measured by the Positive and Negative Affect Scale, in a mental‐health treatment center located in Utah, USA. Fifty‐seven eligible participants (50 women, age range: 23–70 years) were included for analysis. Fifteen minutes of bergamot essential oil exposure improved participants' positive feelings compared with the control group (17% higher). Unexpectedly, more participants participated in experimental periods rather than control periods, suggesting even brief exposure to essential oil aroma may make people more willing to enroll in clinical trials. This study provides preliminary evidence of the efficacy and safety of bergamot essential oil inhalation on mental well‐being in a mental health treatment center, suggesting that bergamot essential oil aromatherapy can be an effective adjunct treatment to improve individuals' mental health and well‐being. © 2017 The Authors.

Objective: The purpose of this study was to examine the prevalence and correlates of alcohol-related problems across four Hispanic national groups: Mexican Americans, Puerto Ricans, Cuban Americans, and South/Central Americans. Method: Using a multistage cluster sample design, 5,224 individuals ages 18 years and older were selected from the household population of five U.S. metropolitan areas: Miami, New York, Philadelphia, Houston, and Los Angeles. Results: Cuban Americans had the lowest prevalence of alcohol-related problems. Significant differences across national group for zero versus two or more problems and for one versus two or more problems existed among men. Puerto Rican women were most likely to report two or more problems. The presence of zero versus two or more problems varied significantly across groups. There was variation in problem type across national groups among both men and women. Regression analyses showed that all groups were more likely than Cuban Americans to report two or more problems (vs zero) (Puerto Ricans: odds ratio [OR] = 2.02, p < .05; Mexican Americans: OR = 2.92, p ≤ .01; South/Central Americans: OR = 2.12, p ≤ .01). Being U.S. born (vs foreign born) increased the likelihood of experiencing one (OR = 1.57, p < .05) and two or more problems (OR = 1.95, p ≤ .01). The volume of consumption was associated with problems (one problem: OR = 1.16, p ≤ .01; two or more problems: OR = 1.31, p ≤ .01). Heavy episodic drinking less than once a month was associated with two or more problems (OR= 6.15, p ≤ .01). Heavy episodic drinking one or more times a month was associated with one problem (OR = 1.74, p ≤ .01) and two or more problems (OR = 3.18, p ≤ .01). Conclusions: It is important to recognize that Hispanics are not a homogenous group. PMID:19895778

The need to keep physicians healthy and in practice is critical as demand for doctors grows faster than the supply. Workplace wellness programmes can improve employee health and retain skilled workers. To broaden our understanding about ways to help doctors coping with mental health problems and to develop population-informed workplace wellness recommendations for physician populations. Researchers surveyed physicians to document potential warning signs and prevention strategies. A survey was issued to doctors who presented to a physician health programme with mental health complaints. The survey captured respondents' feedback about how to identify and prevent mental health problems. Data were analyzed using simple descriptive statistics. There were 185 participants. Half of respondents believed their problems could have been recognized sooner and 60% said they exhibited signs that could aid in earlier detection. Potential warnings included fluctuations in mood (67%), increased comments about stress/burnout (49%) and behavioural changes (32%). To improve detection, prevention and care-seeking for mental health problems, doctors endorsed multiple items related to the use of interpersonal supports, personal factors and organizational dynamics throughout the survey. The findings confirmed earlier work demonstrating the value of social and organizational support in maintaining physician health. It further indicated that earlier identification and/or prevention of mental health problems is not only possible, but that medical organizations are uniquely situated to carry out this work.

Neurologic manifestations of chronic methamphetamine abuse

Rusyniak, Daniel E.

2011-01-01

Summary Chronic methamphetamine abuse has devastating effects on the central nervous system. The degree to which addicts will tolerate the dysfunction in the way they think, feel, move, and even look, is a powerful testimony to the addictive properties of this drug. While the mechanisms behind these disorders are complex, at their heart they involve the recurring increase in the concentrations of central monoamines with subsequent dysfunction in dopaminergic neurotransmission. The mainstay of treatment for the problems associated with chronic methamphetamine abuse is abstinence. However, by recognizing the manifestations of chronic abuse, clinicians will be better able to help their patients get treatment for their addiction and to deal with the neurologic complications related to chronic abuse.

Travel, migration and HIV.

Hawkes, S J; Hart, G J

1993-01-01

This is a review of recent publications on the subject of travel (taken in its widest sense) and HIV/AIDS. As with all epidemics caused by transmissible pathogens, AIDS has been seen in many countries as an imported problem. What this perspective fails to recognize is that with the explosion of international travel in the past thirty years it is virtually impossible to prevent the spread of infectious disease across international frontiers. Here we highlight the relative paucity of studies that describe or investigate the context in which sexual risk behaviour of travellers takes place, and suggest areas of further research which could increase understanding of the nature of sexual risk taking, and help in the design of health education programmes.

Safe in the city.

Workplace danger and violence are complex problems that affect nurses more often than is recognized. The home healthcare work environment is challenging enough without the additional risks associated with working out in the open or within a client's home. Every clinician working in home health today understands the demands of visits or extended care in the home and often reluctantly accepts the involved risk. The clinician working in the rural setting may experience similar challenges, but in large metropolitan cities, it has become increasingly frightening as crime, drug use, gangs, violence, homelessness, and transportation issues have made the clinician's job much tougher. It is important to renew awareness and remind clinicians to maintain constant vigilance for personal safety.

Schimmel, P

To conceptualize the essence of the mind-body or mind-brain problem as one of metaphysics rather than science, and to propose a formulation of the problem in the context of current scientific knowledge and its limitations. The background and conceptual parameters of the mind-body problem are delineated, and the limitations of brain research in formulating a solution identified. The problem is reformulated and stated in terms of two propositions. These constitute a 'double aspect theory'. The problem appears to arise as a consequence of the conceptual limitations of the human mind, and hence remains essentially a metaphysical one. A 'double aspect theory' recognizes the essential unity of mind and brain, while remaining consistent with the dualism inherent in human experience.

Harjai, Prashant Kumar; Tiwari, Ruby

2009-01-01

Diagnostic reasoning refers to the analytical processes used to determine patient health problems. While the education curriculum and health care system focus on training nurse clinicians to accurately recognize and rescue clinical situations, assessments of non-expert nurses have yielded less than satisfactory data on diagnostic competency. The contrast between the expert and non-expert nurse clinician raises the important question of how differences in thinking may contribute to a large divergence in accurate diagnostic reasoning. This article recognizes superior organization of one's knowledge base, using prototypes, and quick retrieval of pertinent information, using similarity recognition as two reasons for the expert's superior diagnostic performance. A model of critical diagnostic reasoning, using prototypes and similarity recognition, is proposed and elucidated using case studies. This model serves as a starting point toward bridging the gap between clinical data and accurate problem identification, verification, and management while providing a structure for a knowledge exchange between expert and non-expert clinicians.

China has experienced dramatic industrialization, urbanization, and economic growth over the last 3 decades. The rapid transformation and dramatic prosperity of industries in rural areas have, in turn, created tremendous challenges for occupational health and safety (OHS). This article was prepared to address occupational health and safety issues in township- and village-owned enterprises (TVEs) from several aspects, including working conditions and workplace hazards, major recognized OHS problems, implications of TVE industries to environmental health, and migrant workers. Among the major recognized OHS problems, pneumoconiosis, chemical poisoning, and workplace accidents, especially in small-scale coal mines, are highlighted. It is suggested that the national polices and regulations that specifically target TVEs are indispensable and a more powerful administrative structure should be established to ensure that the pertinent polices, regulations, and OHS standards can be enforced widely and effectively in practice.

Insights on antimicrobial resistance, biofilms and the use of phytochemicals as new antimicrobial agents.

PubMed

Borges, Anabela; Saavedra, Maria J; Simões, Manuel

2015-01-01

Antimicrobial resistance is one of the most serious public health problems. This is of particular concern when bacteria become resistant to various antimicrobial agents simultaneously and when they form biofilms. Consequently, therapeutic options for the treatment of infections have become limited, leading frequently to recurrent infections, treatment failure and increase of morbidity and mortality. Both, persistence and spread of antibiotic resistance, in combination with decreased effectiveness and increased toxicity of current antibiotics have emphasized the urgent need to search alternative sources of antimicrobial substances. Plants are recognized as a source of unexplored chemical structures with high therapeutic potential, including antimicrobial activity against clinically important microorganisms. Additionally, phytochemicals (plant secondary metabolites) present several advantages over synthetic molecules, including green status and different mechanisms of action from antibiotics which could help to overcome the resistance problem. In this study, an overview of the main classes of phytochemicals with antimicrobial properties and their mode of action is presented. A revision about the application of phytochemicals for biofilm prevention and control is also done. Moreover, the use of phytochemicals as scaffolds of new functional molecules to expand the antibiotics pipeline is reviewed.

Organ transplantation is recognized worldwide as an effective treatment for organ failure. However, due to the increase in the number of patients requiring a transplant, a shortage of suitable organs for transplantation has become a global problem. Human organ trade is an illegal practice of buying or selling organs and is universally sentenced. The aim of this study was to search social network for organ trade and offerings in Saudi Arabia. The study was conducted from June 22, 2015 to February 19, 2016. The search was conducted on Twitter, Google answers, and Facebook using the following terms: kidney for sale, kidneys for sale, liver for sale, kidney wanted, liver wanted, kidney donor, and liver donor. We found a total of 557 adverts on organ trade, 165 (30%) from donors or sellers, and 392 (70%) from recipients or buyers. On Twitter, we found 472 (85%) adverts, on Google answers 61 (11%), and on Facebook 24 (4%). Organ trade is a global problem, and yet it is increasingly seen in many countries. Although the Saudi Center for Organ Transplantation by-laws specifically prohibits and monitors any form of commercial transplantation, it is still essential to enforce guidelines for medical professionals to detect and prevent such criminal acts.

Enhanced radioactivity due to natural oil and gas production and related radiological problems.

Kolb, W A; Wojcik, M

Increased gamma radiation detected incidentally a few years ago in a North German oil field was traceable to radioactive scale. At the request of the Federal Ministry of the Interior a survey program was then established for dose rate measurements at various production sites, assessment of the radionuclide content of brines and scale and the Rn-222 content of natural gas. Dose equivalent rates of up to 50 mu Sv/h have been measured at the external surface of storage tanks for brines, but 73% of the 160 sites investigated did not show an increase above the natural background. Brines from gas fields contained Ra-226 of up to 286 Bq/l and scale of up to 1 kBq/g. In brines and scale from oil fields Ra-228 was usually the predominant radionuclide. Some samples contained "unsupported" Pb-210 and even Ac-227, too, but practically no uranium or thorium. The Rn-222 concentrations in natural gas samples varied between 0.004 and 4 Bq/l with a mean value of 0.6 Bq/l. It is shown that the radiation exposure due to natural gas consumption is negligible but some other problems or radiological relevance are recognized.

Challenges in Developing XML-Based Learning Repositories

NASA Astrophysics Data System (ADS)

Auksztol, Jerzy; Przechlewski, Tomasz

There is no doubt that modular design has many advantages, including the most important ones: reusability and cost-effectiveness. In an e-leaming community parlance the modules are determined as Learning Objects (LOs) [11]. An increasing amount of learning objects have been created and published online, several standards has been established and multiple repositories developed for them. For example Cisco Systems, Inc., "recognizes a need to move from creating and delivering large inflexible training courses, to database-driven objects that can be reused, searched, and modified independent of their delivery media" [6]. The learning object paradigm of education resources authoring is promoted mainly to reduce the cost of the content development and to increase its quality. A frequently used metaphor of Learning Objects paradigm compares them to Lego Logs or objects in Object-Oriented program design [25]. However a metaphor is only an abstract idea, which should be turned to something more concrete to be usable. The problem is that many papers on LOs end up solely in metaphors. In our opinion Lego or OO metaphors are gross oversimplificatation of the problem as there is much easier to develop Lego set or design objects in OO program than develop truly interoperable, context-free learning content1.

Solving Word Problems using Schemas: A Review of the Literature

Powell, Sarah R.

2011-01-01

Solving word problems is a difficult task for students at-risk for or with learning disabilities (LD). One instructional approach that has emerged as a valid method for helping students at-risk for or with LD to become more proficient at word-problem solving is using schemas. A schema is a framework for solving a problem. With a schema, students are taught to recognize problems as falling within word-problem types and to apply a problem solution method that matches that problem type. This review highlights two schema approaches for 2nd- and 3rd-grade students at-risk for or with LD: schema-based instruction and schema-broadening instruction. A total of 12 schema studies were reviewed and synthesized. Both types of schema approaches enhanced the word-problem skill of students at-risk for or with LD. Based on the review, suggestions are provided for incorporating word-problem instruction using schemas. PMID:21643477

Children with autism spectrum disorders (ASD) often present with emotional and behavioral problems, which could change the clinical course, especially during childhood, and affect future quality of life. The aim of this study was to clarify the age- and sex-related differences of these problems in ASD. The study subjects were 173 patients with ASD (age: 4-16 years) and 173 age- and sex-matched community children (control group). The parent version of the Strengths and Difficulties Questionnaire was used for comparison of the emotional and behavioral problems between the two groups. The Strengths and Difficulties Questionnaire scores were significantly higher in children with ASD than controls at all ages. The score of total difficulties was significantly higher in girls with ASD than in boys, while the score in male controls was significantly higher than in female controls. Age-related differences in emotional and behavioral problems were observed both in children with ASD and controls, but the characteristics were different: in children with ASD, emotional symptoms and peer problems in both sexes and conduct problems in girls increased significantly with age, while none of the problems in the controls changed with age except for a decrease in the score of hyperactivity/inattention developmentally in both sexes. Prosocial behaviors of children with ASD and controls showed small changes with age. Emotional and behavioral problems are common in children with ASD and showed age- and sex-related differences. Our study emphasizes the importance of recognizing those differences among children with ASD for early intervention. © 2014 The Authors.

The purpose of this article is to review the current status of health care-related infections (HCRI) in low- and middle-income countries (LMIC). HCRI in LMIC are being recognized as an important health problem globally. Despite important efforts, complex medical and non-medical problems prevail. The HCRI burden in LMIC is bigger than in developed countries, with prevalence between 5.7 and 19.1%. The impact on patients, their families, and the hospital systems is high, but has been largely underestimated. During the last 30 years, some progress has been made, with an increased awareness from the medical community and some very successful programs; however, there is a huge gap for improvement and success. In many health care facilities, there is a need of functional surveillance programs, continuous supply of antiseptics, safe water supply, personal protective equipment, essential antibiotics to treat infections, appropriate number of health care personnel trained in infection control, and appropriate health care infrastructure and political commitment.

Over the last 30 years overweight and obesity among adults and children have been on the rise, and since 1997 WHO has designated obesity as a major public health problem. In Greece both adult and childhood obesity is now recognized as an epidemic problem, probably more important than in other European countries. The issue is more serious in male adolescents and adults. There is also a tendency for weight increase along the last 30 years. Metabolic syndrome and type 2 diabetes mellitus are also rising rapidly in the Greek population. The reasons for this epidemic in Greece are not clear. Possible explanations could emerge from the delayed but sharp economic evolution of the country, as well as the abandonment of the traditional Mediterranean diet. Other predisposing factors in Greek children are parental obesity, frequent television viewing, low rates of breastfeeding and, in adolescent girls, smoking and alcohol consumption. Emerging measures are needed to confront this epidemic.

Why "improved" water sources are not always safe.

2014-04-01

Existing and proposed metrics for household drinking-water services are intended to measure the availability, safety and accessibility of water sources. However, these attributes can be highly variable over time and space and this variation complicates the task of creating and implementing simple and scalable metrics. In this paper, we highlight those factors - especially those that relate to so-called improved water sources - that contribute to variability in water safety but may not be generally recognized as important by non-experts. Problems in the provision of water in adequate quantities and of adequate quality - interrelated problems that are often influenced by human behaviour - may contribute to an increased risk of poor health. Such risk may be masked by global water metrics that indicate that we are on the way to meeting the world's drinking-water needs. Given the complexity of the topic and current knowledge gaps, international metrics for access to drinking water should be interpreted with great caution. We need further targeted research on the health impacts associated with improvements in drinking-water supplies.

The Internet has turned during the past decade into a major information resource in various domains of life and a communication venue among adolescents who seek health information via the net. The increasing availability of computers in homes, as well as wireless Internet access, means that adolescents today can go online anywhere, at any time. The media are not the leading cause of any major health problem, but they do contribute significantly to a variety of adolescent health problems, including aggressive behavior, sexual activity, drug use, obesity, sleep disorders, eating disorders, depression, suicide and self harm. This paper focuses on 3 major health issues in adolescents' Internet use: Body image and eating behaviors; sexuality and reproductive health behaviors; and self harm and suicidal behavior. This paper also demonstrates Internet venues where reliable health information is provided to young people by health professionals. Health professionals need to recognize the hazards of adolescents Internet use, and to address potential Internet abuse when encountering adolescents in clinical settings.

A Lossy Compression Technique Enabling Duplication-Aware Sequence Alignment

PubMed Central

Freschi, Valerio; Bogliolo, Alessandro

2012-01-01

In spite of the recognized importance of tandem duplications in genome evolution, commonly adopted sequence comparison algorithms do not take into account complex mutation events involving more than one residue at the time, since they are not compliant with the underlying assumption of statistical independence of adjacent residues. As a consequence, the presence of tandem repeats in sequences under comparison may impair the biological significance of the resulting alignment. Although solutions have been proposed, repeat-aware sequence alignment is still considered to be an open problem and new efficient and effective methods have been advocated. The present paper describes an alternative lossy compression scheme for genomic sequences which iteratively collapses repeats of increasing length. The resulting approximate representations do not contain tandem duplications, while retaining enough information for making their comparison even more significant than the edit distance between the original sequences. This allows us to exploit traditional alignment algorithms directly on the compressed sequences. Results confirm the validity of the proposed approach for the problem of duplication-aware sequence alignment. PMID:22518086

The human and economic cost of hidden hunger.

Micronutrient malnutrition is a public health problem in many developing countries. Its negative impact on income growth is recognized in principle, but there are widely varying estimates of the related economic cost. To discuss available studies that quantify the cost of micronutrient malnutrition, and to develop an alternative framework and apply it to India. Detailed burden of disease calculations are used to estimate the economic cost of micronutrient malnutrition based on disability-adjusted life years (DALYs) lost. The short-term economic cost of micronutrient malnutrition in India amounts to 0.8% to 2.5% of the gross domestic product. Although the results confirm that micronutrient malnutrition is a huge economic problem, the estimates are lower than those of most previous studies. The differences may be due to differences in underlying assumptions, quality of data, and precision of calculation, but also to dynamic interactions between nutrition, health, and economic productivity, which are difficult to capture. Clear explanation of all calculation details would be desirable for future studies in order to increase credibility and transparency.

2016-01-01

Visual odometry (VO) estimation from blurred image is a challenging problem in practical robot applications, and the blurred images will severely reduce the estimation accuracy of the VO. In this paper, we address the problem of visual odometry estimation from blurred images, and present an adaptive visual odometry estimation framework robust to blurred images. Our approach employs an objective measure of images, named small image gradient distribution (SIGD), to evaluate the blurring degree of the image, then an adaptive blurred image classification algorithm is proposed to recognize the blurred images, finally we propose an anti-blurred key-frame selection algorithm to enable the VO robust to blurred images. We also carried out varied comparable experiments to evaluate the performance of the VO algorithms with our anti-blur framework under varied blurred images, and the experimental results show that our approach can achieve superior performance comparing to the state-of-the-art methods under the condition with blurred images while not increasing too much computation cost to the original VO algorithms.

Oral health problems have been increasingly recognized as important factors causing a negative impact on daily performance and quality of life. The purpose of this study was to assess the impact of tooth extraction with no replacement, untreated fractured anterior teeth, malocclusion, dental restorations, and orthodontic braces on the quality of life in Nigerian schoolchildren. A total of 197 9- to 17-year-old schoolchildren completed the Oral Health Impact Profile (OHIP) index/questionnaire. Students who had tooth extraction with no replacement and untreated fractured incisors had significantly higher mean OHIP scores for functional limitations, physical pain, psychological discomfort, physical, psychological, and social disabilities, and handicaps (P<.001) when compared to other groups and the control. The mean OHIP scores of students with features of malocclusion were significantly higher for functional limitations, psychological discomfort, and psychological disability compared to the control group (P<.001). Untreated dental problems had some negative impact on the quality of life on the 7 subscales of the OHIP.

Vocal cord paralysis in children.

PubMed

King, Ericka F; Blumin, Joel H

2009-12-01

Vocal fold paralysis (VFP) is an increasingly commonly identified problem in the pediatric patient. Diagnostic and management techniques honed in adult laryngologic practice have been successfully applied to children. Iatrogenic causes, including cardiothoracic procedures, remain a common cause of unilateral VFP. Neurologic disorders predominate in the cause of bilateral VFP. Diagnosis with electromyography is currently being evaluated in children. Treatment of VFP is centered around symptomology, which is commonly divided between voice and airway concerns. Speech therapy shows promise in older children. Surgical management for unilateral VFP with injection laryngoplasty is commonly performed and well tolerated. Laryngeal reinnervation is currently being applied to the pediatric population as a permanent treatment and offers several advantages over laryngeal framework procedures. For bilateral VFP, tracheotomy is still commonly performed. Glottic dilation procedures are performed both openly and endoscopically with a high degree of success. VFP is a well recognized problem in pediatric patients with disordered voice and breathing. Some patients will spontaneously recover their laryngeal function. For those who do not, a variety of reliable techniques are available for rehabilitative treatment.

Diverse knowledges and competing interests: an essay on socio-technical problem-solving.

PubMed

di Norcia, Vincent

2002-01-01

Solving complex socio-technical problems, this paper claims, involves diverse knowledges (cognitive diversity), competing interests (social diversity), and pragmatism. To explain this view, this paper first explores two different cases: Canadian pulp and paper mill pollution and siting nuclear reactors in systematically sensitive areas of California. Solving such socio-technically complex problems involves cognitive diversity as well as social diversity and pragmatism. Cognitive diversity requires one to not only recognize relevant knowledges but also to assess their validity. Finally, it is suggested, integrating the resultant set of diverse relevant and valid knowledges determines the parameters of the solution space for the problem.

Effect of visual media use on school performance: a prospective study.

To identify mechanisms for the impact of visual media use on adolescents' school performance. We conducted a 24-month, four-wave longitudinal telephone study of a national sample of 6,486 youth aged 10 to 14 years. Exposure measures: latent construct for screen exposure time (weekday time spent viewing television/playing videogames, presence of television in bedroom) and variables for movie content (proportion of PG-13 and R movies viewed). self- and parent reports of grades in school. Effects of media exposures on change in school performance between baseline and 24 months were assessed using structural equation modeling. Information about hypothesized mediators (substance use, sensation seeking, and school problem behavior) was obtained at baseline and at the 16-month follow-up. Adjusted for baseline school performance, baseline levels of mediators, and a range of covariates, both screen exposure time and media content had adverse effects on change in school performance. Screen exposure had an indirect effect on poor school performance through increased sensation seeking. Viewing more PG-13 and R-rated movies had indirect effects on poor school performance mediated through increases in substance use and sensation seeking. R-rated viewing also had an indirect effect on poor school performance through increased school behavior problems. The effect sizes of exposure time and content on the intermediate variables and ultimately on school performance were similar to those for previously recognized determinants of these mediators, including household income, parenting style, and adolescents' self-control. These aspects of visual media use adversely affect school performance by increasing sensation seeking, substance use, and school problem behavior. Copyright 2010 Society for Adolescent Medicine.

Prevalence of pre-school children for overweight/obesity in Turkey.

Santas, Fatih; Santas, Gulcan

Most of the studies and interventions are targeted to address undernutrition, but childhood obesity has become a silent killer among children. Developing countries, including Turkey, could recognize the importance of the issue now and have begun to discuss the necessity of studies on this subject. Therefore, this study aims to examine the prevalence of obesity among pre-school children in Turkey. The data source of this study is the Turkey Demographic and Health Survey (TDHS)-2013. The TDHS-2013 was a sample study to gather information about the fertility levels and changes in them, infant and child mortality, family planning, and maternal and infant health at the national level. Overweight/obesity for height was 8.6% and 6.6% for age. Overweight/obesity problems are mostly observed in the West and are higher in urban areas. Overweight/obesity decreases with increasing age. There is a positive correlation between overweight/obesity and maternal educational level. As the household welfare level increases, overweight/obesity increases in pre-school children. Female children are at higher risk of overweight/obesity than males. As birth order increases, overweight/obesity decreases. Children living in other regions have overweight/obesity problems more than the pre-school children living in the East. This study speculates that obesity appears to be a major problem among pre-school children in Turkey. Based on the findings, the current situation of overweight/obesity among pre-school children is so close to many developing and developed countries, whose obesity levels are a greater concern. This finding demonstrates that effective interventions of obesity should begin as early as infancy in Turkey, as it is a developing country.

Increasing numbers of bird species result from taxonomic progress, not taxonomic inflation

PubMed Central

Sangster, George

2009-01-01

The impact and significance of modern taxonomy on other fields in biology have been subjects of much debate. It has been proposed that increasing numbers of vertebrate species are largely owing to ‘taxonomic inflation’. According to this hypothesis, newly recognized species result from reinterpretations of species limits based on phylogenetic species concepts (PSCs) rather than from new discoveries. Here, I examine 747 proposals to change the taxonomic rank of birds in the period 1950–2007. The trend to recognize more species of birds started at least two decades before the introduction of PSCs. Most (84.6%) newly recognized species were supported by new taxonomic data. Proposals to recognize more species resulted from application of all six major taxonomic criteria. Many newly recognized species (63.4%) were not based exclusively on PSC-based criteria (diagnosability, monophyly and exclusive coalescence of gene trees). Therefore, this study finds no empirical support for the idea that the increase in species is primarily epistemological rather than data-driven. This study shows that previous claims about the causes and effects of taxonomic inflation lack empirical support. I argue that a more appropriate term for the increase in species is ‘taxonomic progress’. PMID:19520805

[Problem-solving approach in the training of healthcare professionals].

To discuss the problem-solving approach in the training of healthcare professionals who would be able to act both in academic life and in educational practices in services and communities. This is an analytical description of an experience of problem-based learning in specialization-level training that was developed within a university-level healthcare education institution. The analysis focuses on three perspectives: course design, student-centered learning and the teacher's role. The problem-solving approach provided impetus to the learning experience for these postgraduate students. There was increased motivation, leadership development and teamworking. This was translated through their written work, seminars and portfolio preparation. The evaluation process for these experiences presupposes well-founded practices that express the views of the subjects involved: self-assessment and observer assessment. The impact of this methodology on teaching practices is that there is a need for greater knowledge of the educational theories behind the principles of significant learning, teachers as intermediaries and research as an educational axiom. The problem-solving approach is an innovative response to the challenges of training healthcare professionals. Its potential is recognized, while it is noted that educational innovations are characterized by causing ruptures in consolidated methods and by establishing different ways of responding to demands presented at specific moments. The critical problems were identified, while highlighting the risk of considering this approach to be a technical tool that is unconnected with the design of the teaching policy. Experiences and analyses based on the problem-solving assumptions need to be shared, thus enabling the production of knowledge that strengthens the transformation of educational practices within healthcare.

Prevalence of problematic cell phone use in an adult population in Spain as assessed by the Mobile Phone Problem Use Scale (MPPUS)

PubMed Central

de-Sola, José; Talledo, Hernán; Rubio, Gabriel

2017-01-01

Problematic cell phone use has alarmingly increased in industrialized countries in the past 10 years. For many perpetrators, it can turn into a behavioural addiction, although this is not a recognized medical condition. Although there are many tools for evaluating this use, one of the most widely used tools is the Mobile Phone Problematic Use Scale (MPPUS), which we test on a representative sample of the population in Spain to obtain an estimate of the prevalence of problematic cell phone use in our midst. The age range consists of 16–65 years, with 1,126 surveys conducted. In this population, we verify that the reliability and internal consistency of the MPPUS (α = 0.939) are maintained. Additionally, the construct validity, considering the derived factors (Abuse and Dependence, Craving and Loss of Control, and Dependence on the Social Environment) are aligned with other research and with diverse external criteria of addiction. We establish four categories of users (Casual, Regular, At Risk, and Problematic) and obtain a prevalence of 15.4% among At Risk Users and 5.1% among Problematic Users. This finding implies a total of 20.5% of Users with Problems. A binary logistic regression analysis shows that age, gender, level of education, and daily cell phone use predict problematic cell phone use. The results, based on multiple criteria, show that such problematic use shares features of recognized addictions, affecting large segments of the population and not only adolescents. PMID:28771626

From climate change to hydraulic fracturing, and from drinking water safety to wildfires, environmental challenges are changing. The United States has made substantial environmental protection progress based on media-specific and single pollutant risk-based frameworks. However, today’s environmental problems are increasingly complex and new scientific approaches and tools are needed to achieve sustainable solutions to protect the environment and public health. In this article, we present examples of today’s environmental challenges and offer an integrated systems approach to address them. We provide a strategic framework and recommendations for advancing the application of science for protecting the environment and public health. We posit that addressing 21st century challenges requires transdisciplinary and systems approaches, new data sources, and stakeholder partnerships. To address these challenges, we outline a process driven by problem formulation with the following steps: a ) formulate the problem holistically, b ) gather and synthesize diverse information, c ) develop and assess options, and d ) implement sustainable solutions. This process will require new skills and education in systems science, with an emphasis on science translation. A systems-based approach can transcend media- and receptor-specific bounds, integrate diverse information, and recognize the inextricable link between ecology and human health.

Data philanthropy and the design of the infraethics for information societies.

PubMed

Taddeo, Mariarosaria

2016-12-28

In mature information societies, sharing data is increasingly recognized as a crucial means to foster their development. However, competing tensions on data control and ownership, limited technical understanding, and the lack of an adequate governance framework pose serious challenges to attempts to share data among different actors. Data philanthropy, understood as the donation of data from both individuals and private companies, has been proposed as means to meet these challenges. While at first sight data philanthropy may seem an uncontroversial phenomenon, a closer analysis reveals a bewildering network of problems. In this article, I analyse the role of data philanthropy in contemporary societies and the moral problems that it yields. I argue that the solution to these problems rests on the understanding of the infraethical nature of data philanthropy and on the design of an ethical framework encompassing the right infraethics and the right ethics. This is a framework able to address the changes brought about by the information revolution and to harness the opportunities that these pose for the prosperity of current and future information societies.This article is part of the themed issue 'The ethical impact of data science'. © 2016 The Author(s).

2012-06-01

Previous studies have reported that students employed different problem solving approaches when presented with the same task structured with different representations. In this study, we explored and compared students’ strategies as they attempted tasks from two topical areas, kinematics and work. Our participants were 19 engineering students taking a calculus-based physics course. The tasks were presented in linguistic, graphical, and symbolic forms and requested either a qualitative solution or a value. The analysis was both qualitative and quantitative in nature focusing principally on the characteristics of the strategies employed as well as the underlying reasoning for their applications. A comparison was also made for the same student’s approach with the same kind of representation across the two topics. Additionally, the participants’ overall strategies across the different tasks, in each topic, were considered. On the whole, we found that the students prefer manipulating equations irrespective of the representational format of the task. They rarely recognized the applicability of a “qualitative” approach to solve the problem although they were aware of the concepts involved. Even when the students included visual representations in their solutions, they seldom used these representations in conjunction with the mathematical part of the problem. Additionally, the students were not consistent in their approach for interpreting and solving problems with the same kind of representation across the two topical areas. The representational format, level of prior knowledge, and familiarity with a topic appeared to influence their strategies, their written responses, and their ability to recognize qualitative ways to attempt a problem. The nature of the solution does not seem to impact the strategies employed to handle the problem.

2004-01-01

Marriage and family services have not been widely recognized as part of employee assistance programs (EAP), although family and relational problems are widely cited as sources of problems on the job. EAP clients (N = 800, 97% self-referred) indicated how much family, psychological/emotional, drug, alcohol, employment-related, legal, and medical problems troubled them and the need for services in each area. Psychological/emotional (66%) and family (65%) problem areas frequently were rated "considerable" or "extreme." Both areas were rated as "considerable" or "extreme" by 48.6% of participants. In view of the evidence that marriage and family services can be effective with both family and psychological/emotional problems, professionals who are competent to provide such services have much to offer EAP programs.

The prevalence of occupational health-related problems in dentistry: A review of the literature.

2018-03-27

The study was conducted to report on the scope and prevalence of occupational health related-problems experienced by dentists, dental therapists, and oral hygienists in their practice of dentistry. Professional practice and dental training have many risk factors, and the dental team should be able to recognize these factors to protect themselves. The prevalence of conditions related to the musculoskeletal system, stress, percutaneous injuries, ears, and eyes are of concern. The dental team should also not forget hepatitis B, hepatitis C, and HIV as risks in practice. Dental practitioners should protect themselves by self-recognizing risk factors and by maintaining proper working conditions. The study targeted all empirical research, case studies, and systematic literature reviews written in English. All articles selected were subjected to a data analysis process. Data were captured on an Excel spreadsheet and reported in a comprehensive table. The literature addressing occupational health among dental practitioners included mainly cross-sectional studies and review papers (2001-2016). Forty-nine studies were included in the review. Musculoskeletal disorders remain the most researched occupational health-related problems in dentistry. Eye protection compliance was low among practitioners. Percutaneous injuries especially among young dentists and students were still a concern. Occupational health-related problems are still prevalent in current dentistry practice, despite changes in equipment and surgery design. The reported prevalence of occupational related-health problems and other findings of investigative studies highlight the need for continuous professional education and a need to improve clinical practice aspects of dentistry curricula.

Peak Oil and Coal Fires: How Scientific Fact Becomes Debatable Political Questions

NASA Astrophysics Data System (ADS)

McCurdy, K. M.

2008-12-01

Political consensus in the United States cannot be more different from a scientific consensus. The latter situation allows for resolution of problems large and small based on recognized facts and procedures. Once a compelling problem is recognized the scientific community is able to marshal resources to examine that phenomenon. Political consensus however allows for the unending reconsideration of problems in the political arena depending on the outcome of elections and the intensity and sustained length of citizen interest. Serious problems can be trivialized by election campaign rhetoric, or can fail to rise to the level of aggregation necessary to be considered. Coal fires are an example of the latter while OCS exploration and production is an example of the former. Peak oil is a problem that will be avoided until there is a crisis. With current scientific evidence mounting that an important tipping point is approaching, and that societal collapse is a probable outcome of maintaining the status quo, it is vitally important to understand the structural limitations of government decisions. Long standing consensus in the legislature is transferred to the bureaucracy, which can maintain a policy position long after its electoral support has vanished. A legislature and executive experiencing thin electoral margins (51-54% of the vote or seats) produces a different sort of political environment than what is possible with safe margins (>60%). Supermajorities with veto proof margins (>65%) are rare, but not unknown (e.g. 1935-37; 1965-67) and allow for revolutionary policy innovation.

High Molecular Weight Proteins of Trypanosoma cruzi Reduce Cross-Reaction with Leishmania spp. in Serological Diagnosis Tests

PubMed Central

Cervantes-Landín, Alejandra Yunuen; Martínez, Ignacio; Schabib, Muslim; Espinoza, Bertha

2014-01-01

Chagas disease is caused by the parasite Trypanosoma cruzi. Because of its distribution throughout Latin America, sometimes it can overlap with other parasitic diseases, such as leishmaniasis, caused by Leishmania spp. This might represent a problem when performing serological diagnosis, because both parasites share antigens, resulting in cross-reactions. In the present work we evaluated Mexican sera samples: 83.8% of chagasic patients recognized at least one antigen of high molecular weight (>95 kDa) when evaluated by Western blot. Proteins of 130 kDa and 160 kDa are predominantly being recognized by asymptomatic chagasic patients. When the proteins were extracted using Triton X-100 detergent, a larger number of specific T. cruzi proteins were obtained. This protein fraction can be used to increase specificity to 100% in Western blot assays without losing sensitivity of the test. High molecular weight proteins of T. cruzi include glycoproteins with a great amount of αMan (α-mannose), αGlc (α-glucose), GlcNAc (N-acetylglucosamine), and αGal (α-galactose) content and these structures play an essential role in antigens recognition by antibodies present in patients' sera.

Reframing and addressing horizontal violence as a workplace quality improvement concern.

PubMed

Taylor, Rosemary A; Taylor, Steven S

2018-06-27

To reframe horizontal violence as a quality improvement concern. Although the number of studies exploring horizontal violence has increased, evidence supporting the effectiveness of current interventions is weak and the problem persists. Often framed as an individual or interpersonal issue, horizontal violence has been recognized as a complex phenomenon that can only be understood through an examination of social, individual and organizational factors. As such, interventions to address horizontal violence must be applied systemically and address contributions from all sources. This is a discussion paper. This discussion is based on results of a study of nurses' perceptions of horizontal violence and review of the literature. Context is recognized as a contributing factor in human behavior, yet often overlooked in interventions to address horizontal violence. Moving the focus away from the individual and investigating systems contributions to horizontal violence using existing quality improvement frameworks is suggested. To date, efforts to address horizontal violence have not been proven effective. There is a call for a wider application and investigation of interventions. This reframing provides the system level application suggested and would address a broader range of factors contributing to the perpetuation of the phenomenon. © 2018 Wiley Periodicals, Inc.

Adapting Word Embeddings from Multiple Domains to Symptom Recognition from Psychiatric Notes

Zhang, Yaoyun; Li, Hee-Jin; Wang, Jingqi; Cohen, Trevor; Roberts, Kirk; Xu, Hua

2018-01-01

Mental health is increasingly recognized an important topic in healthcare. Information concerning psychiatric symptoms is critical for the timely diagnosis of mental disorders, as well as for the personalization of interventions. However, the diversity and sparsity of psychiatric symptoms make it challenging for conventional natural language processing techniques to automatically extract such information from clinical text. To address this problem, this study takes the initiative to use and adapt word embeddings from four source domains – intensive care, biomedical literature, Wikipedia and Psychiatric Forum – to recognize symptoms in the target domain of psychiatry. We investigated four different approaches including 1) only using word embeddings of the source domain, 2) directly combining data of the source and target to generate word embeddings, 3) assigning different weights to word embeddings, and 4) retraining the word embedding model of the source domain using a corpus of the target domain. To the best of our knowledge, this is the first work of adapting multiple word embeddings of external domains to improve psychiatric symptom recognition in clinical text. Experimental results showed that the last two approaches outperformed the baseline methods, indicating the effectiveness of our new strategies to leverage embeddings from other domains.

Riahi, Sanaz

2011-09-01

The present study explicates the concept of role stress amongst nurses through an analysis adopted from Walker and Avant; Strategies for Theory Construction in Nursing, 4th edn, Prentice Hall, New Jersey, NY. Role stress has become a significant problem amongst nurses and has created much distress leading to burnout among many in the nursing profession. It is significant to analyse the concept of role stress and its relative attributes and consequences, in order to recognize the necessary antecedents needed to create better conditions for nurses at the workplace. A modified method developed by Walker and Avant was used for this concept analysis. A model representing the concept of role stress was developed through careful consideration of the attributes, consequences, antecedents and empirical referents of role stress. The concept analysis of role stress among nurses at the workplace recognized the vulnerability of the nursing discipline towards burnout and distress in general. It is critical to be aware of the current state of health care and note the increased workload created for nurses. Nurses are at a greater vulnerability for role stress, making it imperative for health care organizations to critically evaluate and establish preventative measures for the concept of role stress. 2011 Blackwell Publishing Ltd.

One of the most pressing problems faced by people recovering from psychiatric disabilities at Singapore Anglican Welfare Council (SAWC) continues to be difficulty in finding jobs. It is posited that recognized certification in various practical, marketable, vocational skills increases employment opportunities for people with psychiatric disabilities. In an effort to provide more effective training and to enhance integration, SAWC started two innovative in-house training programs: the On-tbe-Job Training (OJT) program and the Certificate in Office Skills (COS), both programs approved by the Singapore Institute of Technical Education (ITE). It has been found that people, after completion of the OJT; work with greater confidence and their work quality levels also increase. The COS started in September 1999 and will be completed in November 2000; however, people who participated in the course have responded with great enthusiasm because they were able to focus on a more definite goal in their future.

Radiotherapy-induced hypopituitarism: a review.

PubMed

Sathyapalan, Thozhukat; Dixit, Sanjay

2012-05-01

Hypopituitarism is a disorder caused by impaired hormonal secretions from the hypothalamic-pituitary axis. Radiotherapy is the most common cause of iatrogenic hypopituitarism. The hypothalamic-pituitary axis inadvertently gets irradiated in patients receiving prophylactic cranial radiotherapy for leukemia, total body irradiation and radiotherapy for intracranial, base skull, sinonasal and nasopharyngeal tumors. Radiation-induced hypopituitarism (RIH) is insidious, progressive and largely nonreversible. Mostly, RIH involves one hypothalamic-pituitary axis; however, multiple hormonal axes deficiency starts developing at higher doses. Although the clinical effects of the hypopituitarism are more profound in children and young adults, its implications in older adults are being increasingly recognized. The risk continues to persist or increase up to 10 years following radiation exposure. The clinical management of hypopituitarism is challenging both for the patients and healthcare providers. Here we have reviewed the scale of the problem, the risk factors and the management of RIH.

Automated recognition and extraction of tabular fields for the indexing of census records

Clawson, Robert; Bauer, Kevin; Chidester, Glen; Pohontsch, Milan; Kennard, Douglas; Ryu, Jongha; Barrett, William

2013-01-01

We describe a system for indexing of census records in tabular documents with the goal of recognizing the content of each cell, including both headers and handwritten entries. Each document is automatically rectified, registered and scaled to a known template following which lines and fields are detected and delimited as cells in a tabular form. Whole-word or whole-phrase recognition of noisy machine-printed text is performed using a glyph library, providing greatly increased efficiency and accuracy (approaching 100%), while avoiding the problems inherent with traditional OCR approaches. Constrained handwriting recognition results for a single author reach as high as 98% and 94.5% for the Gender field and Birthplace respectively. Multi-author accuracy (currently 82%) can be improved through an increased training set. Active integration of user feedback in the system will accelerate the indexing of records while providing a tightly coupled learning mechanism for system improvement.

Emerging Infections Program Efforts to Address Health Equity

The Emerging Infections Program (EIP), a collaboration between (currently) 10 state health departments, their academic center partners, and the Centers for Disease Control and Prevention, was established in 1995. The EIP performs active, population-based surveillance for important infectious diseases, addresses new problems as they arise, emphasizes projects that lead to prevention, and develops and evaluates public health practices. The EIP has increasingly addressed the health equity challenges posed by Healthy People 2020. These challenges include objectives to increase the proportion of Healthy People–specified conditions for which national data are available by race/ethnicity and socioeconomic status as a step toward first recognizing and subsequently eliminating health inequities. EIP has made substantial progress in moving from an initial focus on monitoring social determinants exclusively through collecting and analyzing data by race/ethnicity to identifying and piloting ways to conduct population-based surveillance by using area-based socioeconomic status measures.

Renal dysfunction in cholestatic liver disease is multifactorial. Acute kidney injury may develop secondary to renal vasoconstriction in the setting of peripheral vasodilation and relative hypovolemia, tubular obstruction by bile casts, and direct tubular toxicity from bile. Anabolic steroids are frequently used by athletes to boost endurance and increase muscle mass. These agents are a recently recognized cause of hepatotoxicity and jaundice and may lead to acute kidney injury. To increase awareness about this growing problem and to characterize the pathology of acute kidney injury in this setting, we report on a young male who developed acute kidney injury in the setting of severe cholestatic jaundice related to ingestion of anabolic steroids used for bodybuilding. Kidney biopsy showed bile casts within distal tubular lumina, filamentous bile inclusions within tubular cells, and signs of acute tubular injury. This report supports the recently re-emerged concept of bile nephropathy cholemic nephrosis.

Effect of infections and environmental factors on growth and nutritional status in developing countries.

PubMed

Bhutta, Zulfiqar Ahmed

2006-12-01

Despite numerous advances and improvements in child health globally, malnutrition remains a major problem and underlies a significant proportion of child deaths. A large proportion of the hidden burden of malnutrition is represented by widespread single and multiple micronutrient deficiencies. A number of factors may influence micronutrient deficiencies in developing countries, including poor body stores at birth, dietary deficiencies and high intake of inhibitors of absorption such as phytates and increased losses from the body. Although the effects of poor intake and increased micronutrient demands are well described, the potential effects of acute and chronic infections on the body's micronutrient status are less well appreciated. Even more obscure is the potential effect of immunostimulation and intercurrent infections on the micronutrient distribution and homeostasis. The association therefore of relatively higher rates of micronutrient deficiencies with infectious diseases may be reflective of both increased predisposition to infections in deficient populations as well as a direct effect of the infection itself on micronutrient status indicators. Recently the association of increased micronutrient losses such as those of zinc and copper with acute diarrhea has been recognized and a net negative balance of zinc has been shown in zinc metabolic studies in children with persistent diarrhea. It is also recognized that children with shigellosis can lose a significant amount of vitamin A in the urine, thus further aggravating preexisting subclinical vitamin A deficiency. Given the epidemiological association between micronutrient deficiencies and diarrhea, supplementation strategies in endemic areas are logical. The growing body of evidence on the key role of zinc supplementation in accelerating recovery from diarrheal illnesses in developing countries supports its use in public health strategies.

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.

Supporting the development of curricular knowledge among novice physics instructors

Robertson, Amy D.

2018-04-01

In this paper, my aim is to problematize the invisibility (to instructors) of the purposes of particular exercises within research-based instructional materials (RBIMs) and to provide one possible solution to this problem that other teacher educators may adapt for their institutional contexts. In particular, I show that many RBIMs anticipate and respond to particular (often incorrect) learner ideas, that teachers often do not recognize this, and that not recognizing this can cause teachers to miss opportunities to build on learner ideas and/or engage students in scientific practices. I share an instructional activity I designed that is meant to support teachers—including university physics Learning Assistants—in recognizing the purposes of particular questions or sequences of questions within RBIMs, and I illustrate that this activity can be a productive starting place for conversation about RBIMs.

Predicting 3D pose in partially overlapped X-ray images of knee prostheses using model-based Roentgen stereophotogrammetric analysis (RSA).

2014-12-01

After total knee replacement, the model-based Roentgen stereophotogrammetric analysis (RSA) technique has been used to monitor the status of prosthetic wear, misalignment, and even failure. However, the overlap of the prosthetic outlines inevitably increases errors in the estimation of prosthetic poses due to the limited amount of available outlines. In the literature, quite a few studies have investigated the problems induced by the overlapped outlines, and manual adjustment is still the mainstream. This study proposes two methods to automate the image processing of overlapped outlines prior to the pose registration of prosthetic models. The outline-separated method defines the intersected points and segments the overlapped outlines. The feature-recognized method uses the point and line features of the remaining outlines to initiate registration. Overlap percentage is defined as the ratio of overlapped to non-overlapped outlines. The simulated images with five overlapping percentages are used to evaluate the robustness and accuracy of the proposed methods. Compared with non-overlapped images, overlapped images reduce the number of outlines available for model-based RSA calculation. The maximum and root mean square errors for a prosthetic outline are 0.35 and 0.04 mm, respectively. The mean translation and rotation errors are 0.11 mm and 0.18°, respectively. The errors of the model-based RSA results are increased when the overlap percentage is beyond about 9%. In conclusion, both outline-separated and feature-recognized methods can be seamlessly integrated to automate the calculation of rough registration. This can significantly increase the clinical practicability of the model-based RSA technique.

Enlargement of lymph nodes of the neck, slightly elevated body temperature and discomfort are symptoms characteristic of many illnesses. One of these can be toxoplasmosis. Because the rarity of its occurrence, sometimes toxoplasmosis may be last to be recognized. In many cases absence of specific additional examination guidelines can contribute to several problems with correct diagnosis. At the present time, the most reliable sample analysis methods are the examination of levels of antibodies IgG and IgM, and the histopathological verification. The authors also indicate that varying therapeutic effects using prophilactic treatment and insufficient additional examination could lead to diagnostic problems.

A modified form of conjugate gradient method for unconstrained optimization problems

NASA Astrophysics Data System (ADS)

Ghani, Nur Hamizah Abdul; Rivaie, Mohd.; Mamat, Mustafa

2016-06-01

Conjugate gradient (CG) methods have been recognized as an interesting technique to solve optimization problems, due to the numerical efficiency, simplicity and low memory requirements. In this paper, we propose a new CG method based on the study of Rivaie et al. [7] (Comparative study of conjugate gradient coefficient for unconstrained Optimization, Aus. J. Bas. Appl. Sci. 5(2011) 947-951). Then, we show that our method satisfies sufficient descent condition and converges globally with exact line search. Numerical results show that our proposed method is efficient for given standard test problems, compare to other existing CG methods.

Nurturing reliable and robust open-source scientific software

NASA Astrophysics Data System (ADS)

Uieda, L.; Wessel, P.

2017-12-01

Scientific results are increasingly the product of software. The reproducibility and validity of published results cannot be ensured without access to the source code of the software used to produce them. Therefore, the code itself is a fundamental part of the methodology and must be published along with the results. With such a reliance on software, it is troubling that most scientists do not receive formal training in software development. Tools such as version control, continuous integration, and automated testing are routinely used in industry to ensure the correctness and robustness of software. However, many scientist do not even know of their existence (although efforts like Software Carpentry are having an impact on this issue; software-carpentry.org). Publishing the source code is only the first step in creating an open-source project. For a project to grow it must provide documentation, participation guidelines, and a welcoming environment for new contributors. Expanding the project community is often more challenging than the technical aspects of software development. Maintainers must invest time to enforce the rules of the project and to onboard new members, which can be difficult to justify in the context of the "publish or perish" mentality. This problem will continue as long as software contributions are not recognized as valid scholarship by hiring and tenure committees. Furthermore, there are still unsolved problems in providing attribution for software contributions. Many journals and metrics of academic productivity do not recognize citations to sources other than traditional publications. Thus, some authors choose to publish an article about the software and use it as a citation marker. One issue with this approach is that updating the reference to include new contributors involves writing and publishing a new article. A better approach would be to cite a permanent archive of individual versions of the source code in services such as Zenodo (zenodo.org). However, citations to these sources are not always recognized when computing citation metrics. In summary, the widespread development of reliable and robust open-source software relies on the creation of formal training programs in software development best practices and the recognition of software as a valid form of scholarship.

The structure of patients' presenting concerns: the completion relevance of current symptoms.

Robinson, Jeffrey D; Heritage, John

2005-07-01

This article uses conversation analysis to investigate the problem-presentation phase of 302 visits between primary-care physicians and patients with acute problems. It analyzes the social-interactional organization of problem presentation, focusing on how participants recognize and negotiate its completion. It argues that physicians and patients mutually orient to the presentation of current symptoms--that is, concrete symptoms presented as somehow being experienced in the here-and-now--as a locus of transition between the patient-controlled problem-presentation phase of the visit and the physician-controlled information-gathering phase. This is a resource for physicians to distinguish between complete and incomplete presentations, and for patients to manipulate this distinction.

Ubiquitously unhealthy eating and drinking habits and the development of multiple morbidities, including obesity, type-2 diabetes, dental caries and dental erosion have become a major challenge for physicians, dentists and parents. Modernization has provided heaps of option for outdoor eating and sugar-containing drinks. Even the “diet” labeled drinks are considered not free from sugars and enhances calorie input. With the increasing trends of eating unhealthy, sticky and readily available, refined carbohydrate-rich foods and drinks, problems pertaining to body’s metabolic activity and oral health have also been significantly recognized. Dentists and pediatricians can play a pivotal role and should emphasize on patients’ education and counseling on the proper nutritional diet and health. PMID:27672250

Healthcare acquired infections are among the biggest unsolved problems in healthcare, implying an increasing number of deaths, extra-days of hospital stay and hospital costs. Performing hand hygiene is a simple and inexpensive prevention measure, but healthcare workers compliance with it is still far from optimal. Recognized hurdles are lack of time, forgetfulness, wrong technique and lack of motivation. This study aims at exploring gamification to promote nurses' HH compliance self-awareness and action. Real-time data collected from an indoor location system will provide feedback information to a group of nurses working in an ICU ward. In this paper both the research's motivation and methods is presented, along with the first round of results and its discussion.

Cost effective manufacturing of devices at 0.5, 0.35 and 0.25μm geometries will be highly dependent on a companys' ability to obtain an economic return on investment. The high capital investment in equipment and facilities, not to mention the related chemical and wafer costs, for producing 200mm silicon wafers requires aspects of wafer processing to be tightly controlled. Reduction in errors and enhanced yield management requires early correction or avoidance of reticle problems. It is becoming increasingly important to recognize and track all pertinent factors impacting both the technical and financial viability of a wafer manufacturing fabrication area. Reticle related effects on wafer manufacturing can be costly and affect the total quality perceived by the device customer.

A Probabilistic Risk Mitigation Model for Cyber-Attacks to PMU Networks

The power grid is becoming more dependent on information and communication technologies. Complex networks of advanced sensors such as phasor measurement units (PMUs) are used to collect real time data to improve the observability of the power system. Recent studies have shown that the power grid has significant cyber vulnerabilities which could increase when PMUs are used extensively. Therefore, recognizing and responding to vulnerabilities are critical to the security of the power grid. This paper proposes a risk mitigation model for optimal response to cyber-attacks to PMU networks. We model the optimal response action as a mixed integer linear programmingmore » (MILP) problem to prevent propagation of the cyber-attacks and maintain the observability of the power system.« less

Space weather is increasingly recognized as an international problem affecting several different man-made technologies. The ability to understand, monitor and forecast Earth-directed space weather is of paramount importance for our highly technology-dependent society and for the current rapid developments in awareness and exploration within the heliosphere. It is well known that the strength of the Earth's magnetic field changes over long time scales. We use physics-based simulations with the University of Michigan Space Weather Modeling Framework (SWMF) to examine how the magnetosphere, ionosphere, and ground geomagnetic field perturbations respond as the geomagnetic dipole moment changes. We discuss the implication of these results for our community and the end-users of space weather information.

Vegetarian diets and children.

Sanders, T A; Reddy, S

1994-05-01

The diets and growth of children reared on vegetarian diets are reviewed. Excessive bulk combined with low energy density can be a problem for children aged < or = 5 y and can lead to imparied growth. Diets that have a high content of phytate and other modifiers of mineral absorption are associated with an increased prevalence of rickets and iron-deficiency anemia. Vitamin B-12 deficiency is a real hazard in unsupplemented or unfortified vegan and vegetarian diets. It is suggested that vegans and vegetarians should use oils with a low ratio of linoleic to linolenic acid in view of the recently recognized role of docosahexaenoic acid in visual functioning. If known pitfalls are avoided, the growth and development of children reared on both vegan and vegetarian diets appears normal.

2016-01-01

Contamination of waste effluent from hospitals and intensive food animal production with antimicrobial residues is an immense global problem. Antimicrobial residues exert selection pressures that influence the acquisition of antimicrobial resistance and virulence genes in diverse microbial populations. Despite these concerns there is only a limited understanding of how antimicrobial residues contribute to the global problem of antimicrobial resistance. Furthermore, rapid detection of emerging bacterial pathogens and strains with resistance to more than one antibiotic class remains a challenge. A comprehensive, sequence-based genomic epidemiological surveillance model that captures essential microbial metadata is needed, both to improve surveillance for antimicrobial resistance and to monitor pathogen evolution. Escherichia coli is an important pathogen causing both intestinal [intestinal pathogenic E. coli (IPEC)] and extraintestinal [extraintestinal pathogenic E. coli (ExPEC)] disease in humans and food animals. ExPEC are the most frequently isolated Gram negative pathogen affecting human health, linked to food production practices and are often resistant to multiple antibiotics. Cattle are a known reservoir of IPEC but they are not recognized as a source of ExPEC that impact human or animal health. In contrast, poultry are a recognized source of multiple antibiotic resistant ExPEC, while swine have received comparatively less attention in this regard. Here, we review what is known about ExPEC in swine and how pig production contributes to the problem of antibiotic resistance.

Mental health issues have been increasingly recognized as public health problems globally. Their burden is projected to increase over the next several decades. Additional therapies for mental problems are in urgent need worldwide due to the limitations and costs of existing healthcare approaches. Essential oil aromatherapy can provide a cost-effective and safe treatment for many mental problems. This pilot study observed the effects of bergamot essential oil inhalation on mental health and well-being, as measured by the Positive and Negative Affect Scale, in a mental-health treatment center located in Utah, USA. Fifty-seven eligible participants (50 women, age range: 23-70 years) were included for analysis. Fifteen minutes of bergamot essential oil exposure improved participants' positive feelings compared with the control group (17% higher). Unexpectedly, more participants participated in experimental periods rather than control periods, suggesting even brief exposure to essential oil aroma may make people more willing to enroll in clinical trials. This study provides preliminary evidence of the efficacy and safety of bergamot essential oil inhalation on mental well-being in a mental health treatment center, suggesting that bergamot essential oil aromatherapy can be an effective adjunct treatment to improve individuals' mental health and well-being. © 2017 The Authors.

2018-03-09

Crowdsourcing contests (also called innovation challenges, innovation contests, and inducement prize contests) can be used to solicit multisectoral feedback on health programs and design public health campaigns. They consist of organizing a steering committee, soliciting contributions, engaging the community, judging contributions, recognizing a subset of contributors, and sharing with the community. This scoping review describes crowdsourcing contests by stage, examines ethical problems at each stage, and proposes potential ways of mitigating risk. Our analysis was anchored in the specific example of a crowdsourcing contest that our team organized to solicit videos promoting condom use in China. The purpose of this contest was to create compelling 1-min videos to promote condom use. We used a scoping review to examine the existing ethical literature on crowdsourcing to help identify and frame ethical concerns at each stage. Crowdsourcing has a group of individuals solve a problem and then share the solution with the public. Crowdsourcing contests provide an opportunity for community engagement at each stage: organizing, soliciting, promoting, judging, recognizing, and sharing. Crowdsourcing poses several ethical concerns: organizing-potential for excluding community voices; soliciting-potential for overly narrow participation; promoting-potential for divulging confidential information; judging-potential for biased evaluation; recognizing-potential for insufficient recognition of the finalist; and sharing-potential for the solution to not be implemented or widely disseminated. Crowdsourcing contests can be effective and engaging public health tools but also introduce potential ethical problems. We present methods for the responsible conduct of crowdsourcing contests. ©Joseph D Tucker, Stephen W Pan, Allison Mathews, Gabriella Stein, Barry Bayus, Stuart Rennie.

CT of inferior vena cava filters: normal presentations and potential complications.

Georgiou, Nicholas A; Katz, Douglas S; Ganson, George; Eng, Kaitlin; Hon, Man

2015-12-01

With massive pulmonary embolism (PE) being the first or second leading cause of unexpected death in adults, protection against PE is critical in appropriately selected patients. The use of inferior vena cava (IVC) filters has increased over the years, paralleling the increased detection of deep venous thrombosis (DVT) and PE by improved and more available imaging techniques. The use of IVC filters has become very common as an alternative and/or as a supplement to anticoagulation, and these filters are often seen on routine abdominal CT, including in the emergency setting; therefore, knowledge of the normal spectrum of findings of IVC filters by the radiologist on CT is critical. Additionally, CT can be used specifically to identify complications related to IVC filters, and CT may alternatively demonstrate IVC filter-related problems which are not specifically anticipated clinically. With multiple available IVC filters on the US market, and even more available outside of the USA, it is important for the emergency and the general radiologist to recognize the different models and various appearances and positioning on CT, as well as their potential complications. These complications may be related to venous access, but also include thrombosis related to the filter, filter migration and penetration, and problems associated with filter deployment. With the increasing number of inferior vena cava filters placed and their duration within patients increasing over time, it is critical for emergency and other radiologists to be aware of these findings on CT.

Revising explanatory models to accommodate anomalous genetic phenomena: Problem solving in the context of discovery

NASA Astrophysics Data System (ADS)

Hafner, Robert; Stewart, Jim

Past problem-solving research has provided a basis for helping students structure their knowledge and apply appropriate problem-solving strategies to solve problems for which their knowledge (or mental models) of scientific phenomena is adequate (model-using problem solving). This research examines how problem solving in the domain of Mendelian genetics proceeds in situations where solvers' mental models are insufficient to solve problems at hand (model-revising problem solving). Such situations require solvers to use existing models to recognize anomalous data and to revise those models to accommodate the data. The study was conducted in the context of 9-week high school genetics course and addressed: the heuristics charactenstic of successful model-revising problem solving: the nature of the model revisions, made by students as well as the nature of model development across problem types; and the basis upon which solvers decide that a revised model is sufficient (that t has both predictive and explanatory power).

2016-02-01

The aim of this study was to construct a grounded theory that explains the clinical reasoning processes that registered nurses use to recognize delirium in older adults in acute care hospitals. Delirium is under-recognized in acute hospital settings, this may stem from underdeveloped clinical reasoning processes. Little is known about registered nurses' (RNs) clinical reasoning processes in complex situations such as delirium recognition. A grounded theory approach was used to analyse interview data about the clinical reasoning processes of RNs in acute hospital settings. Seventeen RNs were recruited. Concurrent data collection and comparative analysis and theoretical sampling were conducted in 2013-2014. The core category to emerge from the data was 'chasing the mirage', which describes RNs' clinical reasoning processes to recognize delirium during their interaction with older adults. Understanding the reasoning that contributes to delirium under-recognition provides a strategy by which, this problem can be brought to the forefront of RNs' awareness and intervention. Delirium recognition will contribute to quality care for older adults. © 2015 John Wiley & Sons Ltd.

A successful HIV vaccine will likely induce both humoral and cell-mediated immunity, however, the enormous diversity of HIV has hampered the development of a vaccine that effectively elicits both arms of the adaptive immune response. To tackle the problem of viral diversity, T cell-based vaccine approaches have focused on two main strategies (i) increasing the breadth of vaccine-induced responses or (ii) increasing vaccine-induced responses targeting only conserved regions of the virus. The relative extent to which set-point viremia is impacted by epitope-conservation of CD8+ T cell responses elicited during early HIV-infection is unknown but has important implications for vaccine design. To address this question, we comprehensively mapped HIV-1 CD8+ T cell epitope-specificities in 23 ART-naïve individuals during early infection and computed their conservation score (CS) by three different methods (prevalence, entropy and conseq) on clade-B and group-M sequence alignments. The majority of CD8+ T cell responses were directed against variable epitopes (p<0.01). Interestingly, increasing breadth of CD8+ T cell responses specifically recognizing conserved epitopes was associated with lower set-point viremia (r = - 0.65, p = 0.009). Moreover, subjects possessing CD8+ T cells recognizing at least one conserved epitope had 1.4 log10 lower set-point viremia compared to those recognizing only variable epitopes (p = 0.021). The association between viral control and the breadth of conserved CD8+ T cell responses may be influenced by the method of CS definition and sequences used to determine conservation levels. Strikingly, targeting variable versus conserved epitopes was independent of HLA type (p = 0.215). The associations with viral control were independent of functional avidity of CD8+ T cell responses elicited during early infection. Taken together, these data suggest that the next-generation of T-cell based HIV-1 vaccines should focus on strategies that can elicit CD8+ T cell responses to multiple conserved epitopes of HIV-1.

Qualitative adaptation of child behaviour problem instruments in a developing-country setting.

PubMed

Khan, B; Avan, B I

2014-07-08

A key barrier to epidemiological research on child behaviour problems in developing countries is the lack of culturally relevant, internationally recognized psychometric instruments. This paper proposes a model for the qualitative adaptation of psychometric instruments in developing-country settings and presents a case study of the adaptation of 3 internationally recognized instruments in Pakistan: the Child Behavior Checklist, the Youth Self-Report and the Teacher's Report Form. This model encompassed a systematic procedure with 6 distinct phases to minimize bias and ensure equivalence with the original instruments: selection, deliberation, alteration, feasibility, testing and formal approval. The process was conducted in collaboration with the instruments' developer. A multidisciplinary working group of experts identified equivalence issues and suggested modifications. Focus group discussions with informants highlighted comprehension issues. Subsequently modified instruments were thoroughly tested. Finally, the instruments' developer approval further validated the qualitative adaptation. The study proposes a rigorous and systematic model to effectively achieve cultural adaptation of psychometric instruments.

Health care barriers and interventions for battered women.

PubMed Central

Loring, M T; Smith, R W

1994-01-01

Family violence is a major public health problem. Battered women present with multiple physical injuries in hospital emergency rooms, clinics, and personal physicians' offices. Yet, they are often not identified as battered and fail to receive appropriate treatment for the nonphysical effects of these events. Instead, only discrete physical injuries are identified. The authors explore the literature to identify barriers in recognizing and treating battered women. These barriers are viewed as a microcosm of the larger public health problem in which battered women fear identifying themselves and often are not recognized by public health professionals. Some barriers pertain to the victims themselves; others can be attributed to the attitudes of medical care providers in emergency rooms, clinics, and private physicians' offices. The many faceted needs of victims require a variety of interventions including medical models, criminal justice intervention systems, and social models for change. Some intervention strategies that are currently being employed in various programs in the United States are described. PMID:8190856

Emotion perception accuracy and bias in face-to-face versus cyberbullying.

PubMed

Ciucci, Enrica; Baroncelli, Andrea; Nowicki, Stephen

2014-01-01

The authors investigated the association of traditional and cyber forms of bullying and victimization with emotion perception accuracy and emotion perception bias. Four basic emotions were considered (i.e., happiness, sadness, anger, and fear); 526 middle school students (280 females; M age = 12.58 years, SD = 1.16 years) were recruited, and emotionality was controlled. Results indicated no significant findings for girls. Boys with higher levels of traditional bullying did not show any deficit in perception accuracy of emotions, but they were prone to identify happiness and fear in faces when a different emotion was expressed; in addition, male cyberbullying was related to greater accuracy in recognizing fear. In terms of the victims, cyber victims had a global problem in recognizing emotions and a specific problem in processing anger and fear. It was concluded that emotion perception accuracy and bias were associated with bullying and victimization for boys not only in traditional settings but also in the electronic ones. Implications of these findings for possible intervention are discussed.

A deep convolutional neural network for recognizing foods

Controlling the food intake is an efficient way that each person can undertake to tackle the obesity problem in countries worldwide. This is achievable by developing a smartphone application that is able to recognize foods and compute their calories. State-of-art methods are chiefly based on hand-crafted feature extraction methods such as HOG and Gabor. Recent advances in large-scale object recognition datasets such as ImageNet have revealed that deep Convolutional Neural Networks (CNN) possess more representation power than the hand-crafted features. The main challenge with CNNs is to find the appropriate architecture for each problem. In this paper, we propose a deep CNN which consists of 769; 988 parameters. Our experiments show that the proposed CNN outperforms the state-of-art methods and improves the best result of traditional methods 17%. Moreover, using an ensemble of two CNNs that have been trained two different times, we are able to improve the classification performance 21:5%.

The order of cigarette market is a key issue in the tobacco business system. The anti-counterfeiting code, as a kind of effective anti-counterfeiting technology, can identify counterfeit goods, and effectively maintain the normal order of market and consumers' rights and interests. There are complex backgrounds, light interference and other problems in the anti-counterfeiting code images obtained by the tobacco recognizer. To solve these problems, the paper proposes a locating method based on Susan operator, combined with sliding window and line scanning,. In order to reduce the interference of background and noise, we extract the red component of the image and convert the color image into gray image. For the confusing characters, recognition results correction based on the template matching method has been adopted to improve the recognition rate. In this method, the anti-counterfeiting code can be located and recognized correctly in the image with complex background. The experiment results show the effectiveness and feasibility of the approach.

This paper addresses the health problems and opportunities that society will face in 2030. We propose a proactive model to combat the trend towards declining levels of physical activity and increasing obesity. The model emphasizes the need to increase physical activity among individuals of all ages. We focus on the right to move and the benefits of physical activity. The paper introduces a seven-level model that includes cells, creature (individual), clan (family), community, corporation, country, and culture. At each level the model delineates how increased or decreased physical activity influences health and well-being across the life span. It emphasizes the importance of combining multiple disciplines and corporate partners to produce a multifaceted cost-effective program that increases physical activity at all levels. The goal of this paper is to recognize exercise as a powerful, low-cost solution with positive benefits to cognitive, emotional, and physical health. Further, the model proposes that people of all ages should incorporate the “right to move” into their life style, thereby maximizing the potential to maintain health and well-being in a cost-effective, optimally influential manner.

Yale-New Haven Hospital, in partnership with Voluntary Hospital Association (VHA Inc), launched the Women's Heart Advantage program in March 2001. Major program components implemented include (1) a comprehensive initial and ongoing internal communication program; (2) a health promotion initiative including a 24-hour, 7-days-a-week women's heart line staffed by nurses and an Internet health question-and-answer forum; (3) significant ongoing communication with nurses and physicians; (4) a community outreach effort to educate poor and minority women; and (5) an aggressive effort to secure financial partners to underwrite the cost of the program. Before launching the program, a telephone survey of 300 randomly selected New Haven County women ages 40 to 70 years was initiated in January 2001 and repeated in January 2002, 2003, and 2004. Findings include (1) the percentage of women who recognize heart disease as the number-one killer of women their age increased from 26% in 2001 to 59% in 2004, (2) the percentage of women who would call 9-1-1 or go directly to a hospital emergency department increased from 63% in 2002 to 83% in 2004, and (3) the percentage of women aware of recent Women's Heart Advantage program promotion grew from 33% in 2002 to 50% in 2004. Perhaps most importantly, the number of women with heart problems admitted through the hospital's emergency department increased from 1528 per year in 2001 to 1870 per year in 2004 (7.5% annual increase), whereas the number of men with heart problems admitted through the emergency department during the same time period has been relatively low (0.8% annual increase). By linking clinical, public health, and marketing expertise along with finding ways to partner with other organizations, the Women's Heart Advantage program has contributed to remarkable changes in women's awareness, knowledge, and behaviors, suggesting a model for approaching similar health-related problems.

The History, Status, Gaps, and Future Directions of Neurotoxicology in China

Background: Rapid economic development in China has produced serious ecological, environmental, and health problems. Neurotoxicity has been recognized as a major public health problem. The Chinese government, research institutes, and scientists conducted extensive studies concerning the source, characteristics, and mechanisms of neurotoxicants. Objectives: This paper presents, for the first time, a comprehensive history and review of major sources of neurotoxicants, national bodies/legislation engaged, and major neurotoxicology research in China. Methods: Peer-reviewed research and pollution studies by Chinese scientists from 1991 to 2015 were examined. PubMed, Web of Science and Chinese National Knowledge Infrastructure (CNKI) were the major search tools. Results: The central problem is an increased exposure to neurotoxicants from air and water, food contamination, e-waste recycling, and manufacturing of household products. China formulated an institutional framework and standards system for management of major neurotoxicants. Basic and applied research was initiated, and international cooperation was achieved. The annual number of peer-reviewed neurotoxicology papers from Chinese authors increased almost 30-fold since 2001. Conclusions: Despite extensive efforts, neurotoxicity remains a significant public health problem. This provides great challenges and opportunities. We identified 10 significant areas that require major educational, environmental, governmental, and research efforts, as well as attention to public awareness. For example, there is a need to increase efforts to utilize new in vivo and in vitro models, determine the potential neurotoxicity and mechanisms involved in newly emerging pollutants, and examine the effects and mechanisms of mixtures. In the future, we anticipate working with scientists worldwide to accomplish these goals and eliminate, prevent and treat neurotoxicity. Citation: Cai T, Luo W, Ruan D, Wu YJ, Fox DA, Chen J. 2016.

Clinical career ladders: the Moses H. Cone Memorial Hospital.

PubMed

Crouch, J B; Douglas, J B; Wheeler, D S

1989-11-01

A competence- and achievement-based advancement program developed for pharmacists at The Moses H. Cone Memorial Hospital, a 530-bed community teaching hospital, is described. In 1985 pharmacy management recognized the need to provide an incentive program to reward achievements by staff clinical pharmacists, recognize their increased responsibilities, and increase the department's ability to retain qualified practitioners. Adding another rung to the existing administrative career ladder was not desirable, so a new job category, pharmacist II, was created. Employees are evaluated for promotion to pharmacist II on the basis of tenure, performance, and elective professional and service activities. A point system is used to objectively score achievements; to be promoted, an employee must accumulate 50 points during a two-year period. The number of staff pharmacists who can advance is limited not arbitrarily but rather by the application of challenging criteria. Employees are responsible for submitting documentation of their achievements to a review committee, which meets quarterly to evaluate applications and award points. Of 13 applicants since 1985, 10 have been promoted. Because of problems in evaluating the performance of pharmacist II employees, providing them time to conduct research, and incorporating specialty practice areas into the program, plans are being made to institute a more structured career ladder system with separate managerial, clinical, and educational tracks. A competence- and achievement-based advancement program with a single step was an improvement over the former system but lacked the balance and comprehensiveness offered by more structured career ladder programs.

Reproductive Toxicity of T Cells in Early Life: Abnormal Immune Development and Postnatal Diseases.

2017-01-01

Immunity is a balanced status with adequate biological defenses to recognize and fight "non-self", as well as adequate tolerance to recognize "self". To maintain this immune homeostasis, a well-organized T cell immune network is required, which in part depends on the well-controlled development of alternative effector T cells, with different cytokine repertoires. Recent researches have pointed that developing fetal T cells network is a remarkably sensitive toxicological target for adverse factors in early life. Epidemiological and experimental studies showed an inseparable relationship between T cell developmental toxicity and immune diseases in adults. Considering that the inflammatory and immune disorders have become a growing health problem worldwide, increasing attention is now being paid to the T cell developmental toxicity. We propose that adverse factors may have programming effects on the crucial functions of immune system during early life which is critical for fetal T cell development and the establishment of the distinct T cell repertoires balance. The permanently disturbed intrathymic or peripheral T cell development may in turn lead to the immune disorders in later life. In this manuscript, we reviewed how adverse factors affected T cell development in early-life with the consequence of the immune dysfunction and immune diseases, and further elucidate the mechanisms. These mechanisms will be helpful in prevention and treatment of the increased prevalence of immune diseases by interfering those pathways.

FVID: Fishing Vessel Type Identification Based on VMS Trajectories

NASA Astrophysics Data System (ADS)

Huang, Haiguang; Hong, Feng; Liu, Jing; Liu, Chao; Feng, Yuan; Guo, Zhongwen

2018-05-01

Vessel Monitoring System (VMS) provides a new opportunity for quantified fishing research. Many approaches have been proposed to recognize fishing activities with VMS trajectories based on the types of fishing vessels. However, one research problem is still calling for solutions, how to identify the fishing vessel type based on only VMS trajectories. This problem is important because it requires the fishing vessel type as a preliminary to recognize fishing activities from VMS trajectories. This paper proposes fishing vessel type identification scheme (FVID) based only on VMS trajectories. FVID exploits feature engineering and machine learning schemes of XGBoost as its two key blocks and classifies fishing vessels into nine types. The dataset contains all the fishing vessel trajectories in the East China Sea in March 2017, including 10031 pre-registered fishing vessels and 1350 unregistered vessels of unknown types. In order to verify type identification accuracy, we first conduct a 4-fold cross-validation on the trajectories of registered fishing vessels. The classification accuracy is 95.42%. We then apply FVID to the unregistered fishing vessels to identify their types. After classifying the unregistered fishing vessel types, their fishing activities are further recognized based upon their types. At last, we calculate and compare the fishing density distribution in the East China Sea before and after applying the unregistered fishing vessels, confirming the importance of type identification of unregistered fishing vessels.

The findings from several authors confirm that undernutrition at an early age affects brain growth and intellectual quotient. Most part of students with the lowest scholastic achievement scores present suboptimal head circumference (anthropometric indicator of past nutrition and brain development) and brain size. On the other hand, intellectual quotient measured through intelligence tests (Weschler-R, or the Raven Progressives Matrices Test) has been described positively and significantly correlated with brain size measured by magnetic resonance imaging (MRI); in this respect, intellectual ability has been recognized as one of the best predictors of scholastic achievement. Considering that education is the change lever for the improvement of the quality of life and that the absolute numbers of undernourished children have been increasing in the world, is of major relevance to analyse the long-term effects of undernutrition at an early age. The investigations related to the interrelationships between nutritional status, brain development, intelligence and scholastic achievement are of greatest importance, since nutritional problems affect the lowest socioeconomic stratum with negative consequences manifested in school-age, in higher levels of school dropout, learning problems and a low percentage of students enrolling into higher education. This limits the development of people by which a clear economic benefit to increase adult productivity for government policies might be successful preventing childhood malnutrition.

Sex trafficking of adolescents and young adults in the United States: healthcare provider's role.

PubMed

Chaffee, Tonya; English, Abigail

2015-10-01

Sex trafficking of adolescents and young adults is both a human rights violation and a public health problem, globally and in the United States. Healthcare providers, including obstetricians and gynecologists, interact with victims, often while they remain under their traffickers' control, but because of providers' lack of training in identification and response many victims go unrecognized and unaided. This review provides an overview of the definitions of sex trafficking and commercial sexual exploitation, contributing factors, health consequences, recruitment of victims, and identification and response by healthcare providers. The literature on definitions and risk factors associated with sex trafficking is growing; however, literature on healthcare providers' role in addressing sex trafficking remains more limited. It is increasingly recognized that healthcare providers have an important role in victim identification and response and as advocates, collaborating with national, regional, and local agencies to increase awareness of sex trafficking as a public health problem and to address the needs of adolescent and young adult victims and survivors globally and in the United States. As professionals who interact with adolescent and young adult victims of sex trafficking, healthcare providers have an important role: in collaboration with other professionals and agencies they can help to identify, respond to, extricate, protect, and advocate for victims and survivors.

Environmentalism and elitism: a conceptual and empirical analysis

NASA Astrophysics Data System (ADS)

Morrison, Denton E.; Dunlap, Riley E.

1986-09-01

The frequent charge that environmentalism is “elitist” is examined conceptually and empirically. First, the concept of elitism is analyzed by distinguishing between three types of accusations made against the environmental movement: (a) compositional elitism suggests that environmentalists are drawn from privileged socioeconomic strata, (b) ideological elitism suggests that environmental reforms are a subterfuge for distributing benefits to environmentalists and/or costs to others, and (c) impact elitism suggests that environmental reforms, whether intentionally or not, do in fact have regressive social impacts. The evidence bearing on each of the three types of elitism is examined in some detail, and the following conclusions are drawn: Compositional elitism is an exaggeration, for although environmentalists are typically above average in socioeconomic status (as are most sociopolitical activists), few belong to the upper class. Ideological elitism may hold in some instances, but environmentalists have shown increasing sensitivity to equity concerns and there is little evidence of consistent pursuit of self-interest. Impact elitism is the most important issue, and also the most difficult to assess. It appears that there has been a general tendency for environmental reforms to have regressive impacts. However, it is increasingly recognized that problems such as workplace pollution and toxic waste contamination disproportionately affect the lower socioeconomic strata, and thus reforms aimed at such problems will likely have more progressive impacts.

MLA Certification: Its Present Problems and Future Development *

The certification program is reviewed and questions as to the validity of the existing three grades of certification are raised. Large institutions which employ many medical librarians do not officially recognize the certificates. The three types of certificates should be replaced with one certificate or diploma. Problems of meaningful examinations, lack of training facilities, and revision of the curriculum require attention. A program is proposed for the improvement of education for medical librarianship. Public identification of medical librarianship is presently difficult. PMID:6016375

NASA has taken the lead in implementing the concept of technology utilization, and the Technology Utilization Program is the first vital step in the goal of a technological society to insure maximum benefit from the costs of technology. Experience has shown that the active approach to technology transfer is unique and is well received in the medical profession when appropriate problems are tackled. The problem solving approach is a useful one at the precise time when medicine is recognizing the need for new technology.

Overlay and duplicate records pose a particularly insidious problem today for healthcare organizations--and pediatric hospitals in particular--that are introducing new information systems or upgrading their existing systems. Such erroneous records can be costly and time-consuming to identify and correct, and can lead to lost reimbursement and compromised quality of care. To address the problem, senior financial leaders need to recognize the critical importance of data integrity and take steps to ensure that the people and processes are in place to establish and maintain it.

English, R. A.; Benson, R. E.; Bailey, J. V.; Barnes, C. M.

1973-01-01

Radiation protection problems on earth and in space are discussed. Flight through the Van Allen belts and into space beyond the geomagnetic shielding was recognized as hazardous before the advent of manned space flight. Specialized dosimetry systems were developed for use on the Apollo spacecraft, and systems for solar-particle-event warning and dose projection were devised. Radiation sources of manmade origin on board the Apollo spacecraft present additional problems. Methods applied to evaluate and control or avoid the various Apollo radiation hazards are discussed.

Externalizing problems, which are the main reason for youth referrals to mental health agencies, are highly persistent and predict a range of negative outcomes. Youths with externalizing problems are also frequently comorbid with anxiety. Among the most widely recognized evidence-based treatments is cognitive behavioral therapy (CBT). Although CBT principles seem to be sound, effect sizes remain moderate, suggesting improvements could be made to this conventional treatment approach. The main premise of the current pilot study is to investigate the feasibility of implementing a videogame intervention ("Dojo" [Gamedesk, Los Angeles, CA]) that incorporates CBT principles and aims to address the limitations of conventional CBT delivery models, with the ultimate goal of improving outcomes for this difficult-to-treat population. "Dojo" is an emotion management game that helps youths to recognize and control their physiological and emotional arousal. We explored the implementation and user experience of "Dojo" in a sample of eight adolescents in residential treatment for both externalizing and anxiety problems. Participants attended all sessions without complaints. They evaluated "Dojo" very positively and exhibited high compliance during the training sessions. We encountered some problems with session scheduling and obtaining mentor reports. Quantitative data show the predicted decrease in three out of four measurements. The smooth implementation, high user satisfaction, high self-reported compliance during training sessions, and initial outcome results all indicate the high potential "Dojo" holds as an innovative intervention. If additional rigorously designed randomized controlled trials prove to be successful, "Dojo" can be a cost-effective way to engage high-risk youths in effective intervention.

Discrimination against people with mental illness is rife across the globe. Among different types of discrimination is the policy in many countries where persons with mental illness are forbidden to inherit property, and they are not able to enter into a contract in a large number of countries. Using various databases, legislations dealing with law of contract, law of succession/inheritance, and law relating to testamentary capacity (wills) of all UN Member states (193 countries) were studied. With respect to federal countries, the laws of the most populous state as a representative state in the respective country were studied. Only 40 Member States (21%) recognize/allow persons with mental health problems to enter into contracts. Of these, however, only 16 Member States (9%) recognize the right of persons with mental health problems to enter into a contract without any restrictions. The remaining 24 Member States (12%) allow a contract entered into by a person with mental health problems to be invalidated under certain conditions. These countries also make the validity of the contract subject to the capacity to consent or based on the level of understanding of the person with mental health problems. They may allow persons with mental health problems to enter into contracts only for transactions of an insignificant nature or of personal rights. Only 9% of the countries allow people with mental illness to enter into contracts in an unrestricted way. Furthermore, there remain variations between high income and low income states. In spite of international laws in many countries, laws remain discriminatory.

Science Fairs and Observational Science: A Case History from Earth Orbit

NASA Technical Reports Server (NTRS)

Lowman, Paul D., Jr.; Smith, David E. (Technical Monitor)

2002-01-01

Having judged dozens of science fairs over the years, I am repeatedly disturbed by the ground rules under which students must prepare their entries. They are almost invariably required to follow the "scientific method," involving formulating a hypothesis, a test of the hypothesis, and then a project in which this test is carried out. As a research scientist for over 40 years, I consider this approach to science fairs fundamentally unsound. It is not only too restrictive, but actually avoids the most important (and difficult) part of scientific research: recognizing a scientific problem in the first place. A well-known example is one of the problems that, by his own account, stimulated Einstein's theory of special relativity: the obvious fact that when an electric current is induced in a conductor by a magnetic field , it makes no difference whether the field or the conductor is actually (so to speak) moving. There is in other words no such thing as absolute motion. Physics was transformed by Einstein's recognition of a problem. Most competent scientists can solve problems after they have been recognized and a hypothesis properly formulated, but the ability to find problems in the first Place is much rarer. Getting down to specifics, the "scientific method" under which almost all students must operate is actually the experimental method, involving controlled variables, one of which, ideally, is changed at a time. However, there is another type of science that can be called observational science. As it happens, almost all the space research I have carried out since 1959 has been this type, not experimental science.

The prevalence of occupational health-related problems in dentistry: A review of the literature

2017-01-01

The study was conducted to report on the scope and prevalence of occupational health related-problems experienced by dentists, dental therapists, and oral hygienists in their practice of dentistry. Background: Professional practice and dental training have many risk factors, and the dental team should be able to recognize these factors to protect themselves. The prevalence of conditions related to the musculoskeletal system, stress, percutaneous injuries, ears, and eyes are of concern. The dental team should also not forget hepatitis B, hepatitis C, and HIV as risks in practice. Dental practitioners should protect themselves by self-recognizing risk factors and by maintaining proper working conditions. Methods: The study targeted all empirical research, case studies, and systematic literature reviews written in English. All articles selected were subjected to a data analysis process. Data were captured on an Excel spreadsheet and reported in a comprehensive table. Results: The literature addressing occupational health among dental practitioners included mainly cross-sectional studies and review papers (2001-2016). Forty-nine studies were included in the review. Musculoskeletal disorders remain the most researched occupational health-related problems in dentistry. Eye protection compliance was low among practitioners. Percutaneous injuries especially among young dentists and students were still a concern. Conclusion: Occupational health-related problems are still prevalent in current dentistry practice, despite changes in equipment and surgery design. The reported prevalence of occupational related-health problems and other findings of investigative studies highlight the need for continuous professional education and a need to improve clinical practice aspects of dentistry curricula.

Breathlessness in the primary care setting.

PubMed

Baxter, Noel

2017-09-01

Breathlessness is a high-volume problem with 10% of adults experiencing the symptom daily placing a heavy burden on the health and wider economy. As it worsens, they enter the specialist and hospital-based symptom services where costs quickly escalate and people may find themselves in a place not of their choosing. For many, their care will be delivered by a disease or organ specialist and can find themselves passing between physicians without coordination for symptom support. General practitioners (GPs) will be familiar with this scenario and can often feel out of their depth. Recent advances in our thinking about breathlessness symptom management can offer opportunities and a sense of hope when the GP is faced with this situation. Original research, reviews and other findings over the last 12-18 months that pertain to the value that general practice and the wider primary care system can add, include opportunities to help people recognize they have a problem that can be treated. We present systems that support decisions made by primary healthcare professionals and an increasingly strong case that a solution is required in primary care for an ageing and frail population where breathlessness will be common. Primary care practitioners and leaders must start to realize the importance of recognizing and acting early in the life course of the person with breathlessness because its impact is enormous. They will need to work closely with public health colleagues and learn from specialists who have been doing this work usually with people near to the end of life translating the skills and knowledge further upstream to allow people to live well and remain near home and in their communities.
