Multi-objective reverse logistics model for integrated computer waste management.

PubMed

Ahluwalia, Poonam Khanijo; Nema, Arvind K

2006-12-01

This study aimed to address the issues involved in the planning and design of a computer waste management system in an integrated manner. A decision-support tool is presented for selecting an optimum configuration of computer waste management facilities (segregation, storage, treatment/processing, reuse/recycle and disposal) and allocation of waste to these facilities. The model is based on an integer linear programming method with the objectives of minimizing environmental risk as well as cost. The issue of uncertainty in the estimated waste quantities from multiple sources is addressed using the Monte Carlo simulation technique. An illustrated example of computer waste management in Delhi, India is presented to demonstrate the usefulness of the proposed model and to study tradeoffs between cost and risk. The results of the example problem show that it is possible to reduce the environmental risk significantly by a marginal increase in the available cost. The proposed model can serve as a powerful tool to address the environmental problems associated with exponentially growing quantities of computer waste which are presently being managed using rudimentary methods of reuse, recovery and disposal by various small-scale vendors.

Wearing, Jessica R; Nollen, Nikki; Befort, Christie; Davis, Ann M; Agemy, Carolina K

2014-04-01

Pediatric obesity is a serious and prevalent problem. Smartphone technology, which is becoming increasingly available to children of diverse backgrounds, presents a unique opportunity to instill healthy behaviors before the onset of obesity. Past studies have examined the use of smartphone applications as tools of health behavior modification for adults. The present study examines the content of children's exercise and nutrition smartphone apps. Sixty-two iPhone apps were identified and coded by two independent raters for adherence to expert-recommended behaviors (e.g., five fruits/vegetables per day) and strategies (e.g., self-monitoring diet/physical activity) for the prevention of pediatric obesity. App behavioral and strategy index scores were uniformly low. Apps were more likely to address expert-recommended behaviors for the prevention of pediatric obesity (93.5%), whereas few apps addressed recommended strategies (20.9%). The most common behaviors addressed included physical activity (53.2%) and fruit/vegetable consumption (48.3%). Other important behaviors (e.g., screen time [1.6%] and family meals together [1.6%]) were rarely addressed. Current children's diet and exercise apps could be improved with increased adherence to expert-recommended guidelines, especially expert-recommended strategies.

Vu, Cecilia; Rothman, Emily; Kistin, Caroline J; Barton, Kelly; Bulman, Barb; Budzak-Garza, Ann; Olson-Dorff, Denyse; Bair-Merritt, Megan H

The patient-centered medical home (PCMH) seeks to improve population health. However, PCMH models often focus on improving treatment of chronic diseases rather than on addressing psychosocial adversity. We sought to gather key stakeholder input about how PCMHs might feasibly and sustainably address psychosocial adversity within their patient populations. We conducted 25 semistructured interviews with key stakeholders, such as physicians, nurses, medical assistants, and patients. The audiorecorded interviews focused on participants' perceptions of the best ways to modify the PCMH to address patients' psychosocial adversity. To facilitate information gathering, a fictional patient case was presented. Analyses were conducted using a 3-stage content-analysis process. Participants identified provider-related and systems-level changes necessary for addressing these psychosocial adversities effectively. On the provider level, participants thought that practitioners should foster trusting relationships with patients and should be emotionally present as patients describe their life experiences. Participants also emphasized that providers need to have sensitive conversations about adversity and resilience. On a systems level, participants discussed that documentation must balance privacy and include relevant information in the medical record. In addition, care should be delivered not by a single provider but by a team that has a longitudinal relationship with the patient; this care team should include behavioral health support. Participants provided practical strategies and highlighted provider and systems level changes to adequately address patients' prior psychosocial adversity. Future studies need to assess the degree to which such a trauma-informed approach improves patient access, outcomes, and care quality, and reduces cost.

Introduction Lifestyle is a set of goals, plans, values, attitudes, behaviors, and beliefs manifested in the personal and family life of the individual and in her or his social interactions. It is an interdisciplinary concept that involves a health-oriented view of the physical, psychological, social, and spiritual domains of life. Despite their great importance, there is not much knowledge in Iran about healthy lifestyles. The present study is an attempt to address the knowledge of healthy lifestyle in Iran through a review of the literature on the subject. Methods The present systematic review searched Elsevier, SID, Pub Med, Magiran, IranMedex, and Google Scholar databases for relevant articles published between 2000 and 2014. We used various keywords for the searches, including knowledge, lifestyle, health, and Iran. As a result, 62 articles were included in the study. Results There has been a dramatic increase in the publication of articles on lifestyle in Iran over the past 10 years. The results obtained showed that 64% of the articles addressed physical health, 14% addressed psychological health, 10% addressed social health, and 12% addressed spiritual health. Most lifestyle studies conducted in Iran have focused on physical health, and a few have examined the psychological, social, and spiritual aspects of lifestyle. None of the studies has examined the knowledge map of healthy lifestyles in Iran. Conclusion Given the changes in the causes of mortality from infectious and chronic diseases that impose greater medication and treatment costs on the society, and since diseases caused by unhealthy lifestyles have become the leading cause of death, it is essential for health researchers to focus on the root cause of these diseases, i.e., lifestyle and human behaviors.

Which potential harms and benefits of using ginger in the management of nausea and vomiting of pregnancy should be addressed? a consensual study among pregnant women and gynecologists.

PubMed

Shawahna, Ramzi; Taha, Assim

2017-04-08

Nausea and vomiting of pregnancy (NVP) affect approximately 80-90% of the pregnant women. Ginger (Zingiber officinale Roscoe) is the most widely used herbal therapy in the management of NVP. Like conventional therapies, herbal therapies have potential harms and benefits that patients need to be informed about in order to develop their therapy preferences. The aim of this study was to achieve consensus among women who suffered NVP and physicians often consulted by pregnant women on a core list of potential harms and benefits of using ginger to manage NVP to be addressed during clinical consultations. In this study, the Delphi technique was used to achieve consensus on a core list of important harms and benefits of using ginger in the management of NVP to be addressed during the clinical consultation. A Delphi process was followed in two panels in parallel sessions. One panel was composed of 50 gynecologists and other physicians who are often consulted by pregnant women suffering NVP and the other panel was composed of 50 women who suffered NVP. Consensus was achieved on 21 (75%) of the 28 potential harms presented to the panelists. Panelists agreed that potential harms of the anticoagulant effects of ginger, risk with other co-morbidities, and risk of potential allergic reactions are important to address during the clinical consultation. Of the 14 potential benefits presented to the panelists in both panels, consensus was achieved on 13 (92.9%). Partial consensus on 7 potential harms and 1 potential benefit was achieved in both panels. Addressing important potential harms and benefits of using ginger for the management of NVP during the clinical consultations is important in promoting congruence and reducing patient dissatisfaction in clinical practice. Consensus was achieved on a core list of important harms and benefits of using ginger for the management of NVP to be addressed during the clinical consultations by a panel of women and a panel of physicians. Further studies are still needed to investigate what is being addressed during clinical consultations.

An overview of confounding. Part 1: the concept and how to address it.

PubMed

Howards, Penelope P

2018-04-01

Confounding is an important source of bias, but it is often misunderstood. We consider how confounding occurs and how to address confounding using examples. Study results are confounded when the effect of the exposure on the outcome, mixes with the effects of other risk and protective factors for the outcome. This problem arises when these factors are present to different degrees among the exposed and unexposed study participants, but not all differences between the groups result in confounding. Thinking about an ideal study where all of the population of interest is exposed in one universe and is unexposed in a parallel universe helps to distinguish confounders from other differences. In an actual study, an observed unexposed population is chosen to stand in for the unobserved parallel universe. Differences between this substitute population and the parallel universe result in confounding. Confounding by identified factors can be addressed analytically and through study design, but only randomization has the potential to address confounding by unmeasured factors. Nevertheless, a given randomized study may still be confounded. Confounded study results can lead to incorrect conclusions about the effect of the exposure of interest on the outcome. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

Investigation of Consensually Nonmonogamous Relationships.

PubMed

Conley, Terri; Matsick, Jessica; Moors, Amy Catherine; Ziegler, Ali

2017-03-01

We proposed that the premise that monogamy is the exemplary form of romantic partnership underlies much theory and research on relationship quality, and we addressed how this bias has prompted methodological issues that make it difficult to effectively address the quality of nonmonogamous relationships. Because the idea that consensually nonmonogamous (CNM) relationships are functional (i.e., satisfying and of high quality) is controversial, we included a basic study to assess, in a variety of ways, the quality of these relationships. In that study, we found few differences in relationship functioning between individuals engaged in monogamy and those in CNM relationships. We then considered how existing theories could help researchers to understand CNM relationships and how CNM relationships could shed light on relationship processes, and we proposed a model of how CNM and monogamous relationships differ. Finally, in a second study, we determined that even researchers who present data about CNM are affected by the stigma surrounding such relationships. That is, researchers presenting findings favoring polyamory were perceived as more biased than researchers presenting findings favoring monogamy.

Toward a Robust Security Paradigm for Bluetooth Low Energy-Based Smart Objects in the Internet-of-Things

2017-01-01

Bluetooth Low Energy (BLE) has emerged as one of the most promising technologies to enable the Internet-of-Things (IoT) paradigm. In BLE-based IoT applications, e.g., wearables-oriented service applications, the Bluetooth MAC addresses of devices will be swapped for device pairings. The random address technique is adopted to prevent malicious users from tracking the victim’s devices with stationary Bluetooth MAC addresses and accordingly the device privacy can be preserved. However, there exists a tradeoff between privacy and security in the random address technique. That is, when device pairing is launched and one device cannot actually identify another one with addresses, it provides an opportunity for malicious users to break the system security via impersonation attacks. Hence, using random addresses may lead to higher security risks. In this study, we point out the potential risk of using random address technique and then present critical security requirements for BLE-based IoT applications. To fulfill the claimed requirements, we present a privacy-aware mechanism, which is based on elliptic curve cryptography, for secure communication and access-control among BLE-based IoT objects. Moreover, to ensure the security of smartphone application associated with BLE-based IoT objects, we construct a Smart Contract-based Investigation Report Management framework (SCIRM) which enables smartphone application users to obtain security inspection reports of BLE-based applications of interest with smart contracts.

Holocaust cancer patients: a comparative study.

PubMed

Baider, L; Peretz, T; De-Nour, A K

1993-11-01

There is as yet no consensus on the long-term effects of severe life-threatening stresses. In an earlier study (Baider et al. 1992), we gained some understanding of this issue by addressing a specific question: How do individuals who have undergone severe stress in the past cope with a current stress? We investigated whether severe stress occurring in the past had a long-term effect on present coping capabilities. We addressed the question by studying a group of Holocaust survivors (severe past stress) who were diagnosed as having cancer (current stress) and compared them to a matched group of cancer patients with no past history of trauma. The matching was done on most demographic variables (gender, age, marital status, and education), as well as on disease variables (site and stage of cancer, time since cancer diagnosis, previous and present treatments). The results were unequivocal.

Potential effects of the introduction of the discrete address beacon system data link on air/ground information transfer problems

NASA Technical Reports Server (NTRS)

Grayson, R. L.

1981-01-01

This study of Aviation Safety Reporting System reports suggests that benefits should accure from implementation of discrete address beacon system data link. The phase enhanced terminal information system service is expected to provide better terminal information than present systems by improving currency and accuracy. In the exchange of air traffic control messages, discrete address insures that only the intended recipient receives and acts on a specific message. Visual displays and printer copy of messages should mitigate many of the reported problems associated with voice communications. The problems that remain unaffected include error in addressing the intended recipient and messages whose content is wrong but are otherwise correct as to format and reasonableness.

Résumés are screened rapidly, with some reports stating that recruiters form their impressions within 10 seconds. Certain résumé characteristics can have a significant impact on the snap judgments these recruiters make. The main goal of the present study was to examine the effect of the e-mail address (formal vs. informal) used in a résumé on the hirability perceptions formed by professional recruiters (N=73). In addition, the effect of the e-mail address on hirability perceptions was compared to the effects of spelling errors and typeface. Participants assessed the cognitive ability, personality, and the hirability of six fictitious applicants for the job of an HR specialist. The hirability ratings for the résumés with informal e-mail addresses were significantly lower than the hirability ratings for résumés that featured a formal e-mail address. The effect of e-mail address was as strong as the effect of spelling errors and stronger than that of typeface. The effect of e-mail address on hirability was mediated by perceptions of conscientiousness and honesty-humility. This study among actual recruiters shows for the first time that the choice of the e-mail address used on a résumé might make a real difference.

Lossos, Izidore S.; Gascoyne, Randy D.

2011-01-01

Histological transformation of follicular lymphoma (FL) to a more aggressive non-Hodgkin's lymphomas is a pivotal event in the natural history of FL and is associated with poor outcome. While commonly observed in clinical practice and despite multiple studies designed to address its pathogenesis, the biology of this process represents an enigma. In this chapter we present a state of the art review summarizing the definition of histologic transformation, its incidence, pathogenesis, clinical manifestations, treatment and outcome. Furthermore, we specifically emphasize gaps in our knowledge that should be addressed in future studies. PMID:21658615

Application of network methods for understanding evolutionary dynamics in discrete habitats.

PubMed

Greenbaum, Gili; Fefferman, Nina H

2017-06-01

In populations occupying discrete habitat patches, gene flow between habitat patches may form an intricate population structure. In such structures, the evolutionary dynamics resulting from interaction of gene-flow patterns with other evolutionary forces may be exceedingly complex. Several models describing gene flow between discrete habitat patches have been presented in the population-genetics literature; however, these models have usually addressed relatively simple settings of habitable patches and have stopped short of providing general methodologies for addressing nontrivial gene-flow patterns. In the last decades, network theory - a branch of discrete mathematics concerned with complex interactions between discrete elements - has been applied to address several problems in population genetics by modelling gene flow between habitat patches using networks. Here, we present the idea and concepts of modelling complex gene flows in discrete habitats using networks. Our goal is to raise awareness to existing network theory applications in molecular ecology studies, as well as to outline the current and potential contribution of network methods to the understanding of evolutionary dynamics in discrete habitats. We review the main branches of network theory that have been, or that we believe potentially could be, applied to population genetics and molecular ecology research. We address applications to theoretical modelling and to empirical population-genetic studies, and we highlight future directions for extending the integration of network science with molecular ecology. © 2017 John Wiley & Sons Ltd.

[Who Hits the Mark? A Comparative Study of the Free Geocoding Services of Google and OpenStreetMap].

Lemke, D; Mattauch, V; Heidinger, O; Hense, H W

2015-09-01

Geocoding, the process of converting textual information (addresses) into geographic coordinates is increasingly used in public health/epidemiological research and practice. To date, little attention has been paid to geocoding quality and its impact on different types of spatially-related health studies. The primary aim of this study was to compare 2 freely available geocoding services (Google and OpenStreetMap) with regard to matching rate (percentage of address records capable of being geocoded) and positional accuracy (distance between geocodes and the ground truth locations). Residential addresses were geocoded by the NRW state office for information and technology and were considered as reference data (gold standard). The gold standard included the coordinates, the quality of the addresses (4 categories), and a binary urbanity indicator based on the CORINE land cover data. 2 500 addresses were randomly sampled after stratification for address quality and urbanity indicator (approximately 20 000 addresses). These address samples were geocoded using the geocoding services from Google and OSM. In general, both geocoding services showed a decrease in the matching rate with decreasing address quality and urbanity. Google showed consistently a higher completeness than OSM (>93 vs. >82%). Also, the cartographic confounding between urban and rural regions was less distinct with Google's geocoding API. Regarding the positional accuracy of the geo-coordinates, Google also showed the smallest deviations from the reference coordinates, with a median of <9 vs. <175.8 m. The cumulative density function derived from the positional accuracy showed for Google that nearly 95% and for OSM 50% of the addresses were geocoded within <50 m of their reference coordinates. The geocoding API from Google is superior to OSM regarding completeness and positional accuracy of the geocoded addresses. On the other hand, Google has several restrictions, such as the limitation of the requests to 2 500 addresses per 24 h and the presentation of the results exclusively on Google Maps, which may complicate the use for scientific purposes. © Georg Thieme Verlag KG Stuttgart · New York.

Car indoor air pollution - analysis of potential sources

PubMed Central

2011-01-01

The population of industrialized countries such as the United States or of countries from the European Union spends approximately more than one hour each day in vehicles. In this respect, numerous studies have so far addressed outdoor air pollution that arises from traffic. By contrast, only little is known about indoor air quality in vehicles and influences by non-vehicle sources. Therefore the present article aims to summarize recent studies that address i.e. particulate matter exposure. It can be stated that although there is a large amount of data present for outdoor air pollution, research in the area of indoor air quality in vehicles is still limited. Especially, knowledge on non-vehicular sources is missing. In this respect, an understanding of the effects and interactions of i.e. tobacco smoke under realistic automobile conditions should be achieved in future. PMID:22177291

New perspectives on evolutionary medicine: the relevance of microevolution for human health and disease.

PubMed

Rühli, Frank Jakobus; Henneberg, Maciej

2013-04-29

Evolutionary medicine (EM) is a growing field focusing on the evolutionary basis of human diseases and their changes through time. To date, the majority of EM studies have used pure theories of hominin macroevolution to explain the present-day state of human health. Here, we propose a different approach by addressing more empirical and health-oriented research concerning past, current and future microevolutionary changes of human structure, functions and pathologies. Studying generation-to-generation changes of human morphology that occurred in historical times, and still occur in present-day populations under the forces of evolution, helps to explain medical conditions and warns clinicians that their current practices may influence future humans. Also, analyzing historic tissue specimens such as mummies is crucial in order to address the molecular evolution of pathogens, of the human genome, and their coadaptations.

Steady-state configurations and dynamics of the MreB helix within bacteria

NASA Astrophysics Data System (ADS)

Rutenberg, Andrew; Allard, Jun

2007-03-01

We present a quantitative model of the actin-like MreB cytoskeleton that is present in many prokaryotes. Individual MreB polymers are bundled into a supra-molecular array to make up helical cables. The cell wall imposes constraint forces through a global elasticity model. With variational techniques and stochastic simulations we obtain relationships between observable quantities such as the pitch of the helix, the total abundance of MreB molecules, and the thickness of the MreB cables. We address changes expected with slow cell growth, as well as turnover dynamics that are relevant to FRAP studies. We also address polarized macromolecular trafficking along the MreB cables without motor proteins.

Methods used to address fidelity of receipt in health intervention research: a citation analysis and systematic review.

PubMed

Rixon, Lorna; Baron, Justine; McGale, Nadine; Lorencatto, Fabiana; Francis, Jill; Davies, Anna

2016-11-18

The American Behaviour Change Consortium (BCC) framework acknowledges patients as active participants and supports the need to investigate the fidelity with which they receive interventions, i.e. receipt. According to this framework, addressing receipt consists in using strategies to assess or enhance participants' understanding and/or performance of intervention skills. This systematic review aims to establish the frequency with which receipt is addressed as defined in the BCC framework in health research, and to describe the methods used in papers informed by the BCC framework and in the wider literature. A forward citation search on papers presenting the BCC framework was performed to determine the frequency with which receipt as defined in this framework was addressed. A second electronic database search, including search terms pertaining to fidelity, receipt, health and process evaluations was performed to identify papers reporting on receipt in the wider literature and irrespective of the framework used. These results were combined with forward citation search results to review methods to assess receipt. Eligibility criteria and data extraction forms were developed and applied to papers. Results are described in a narrative synthesis. 19.6% of 33 studies identified from the forward citation search to report on fidelity were found to address receipt. In 60.6% of these, receipt was assessed in relation to understanding and in 42.4% in relation to performance of skill. Strategies to enhance these were present in 12.1% and 21.1% of studies, respectively. Fifty-five studies were included in the review of the wider literature. Several frameworks and operationalisations of receipt were reported, but the latter were not always consistent with the guiding framework. Receipt was most frequently operationalised in relation to intervention content (16.4%), satisfaction (14.5%), engagement (14.5%), and attendance (14.5%). The majority of studies (90.0%) included subjective assessments of receipt. These relied on quantitative (76.0%) rather than qualitative (42.0%) methods and studies collected data on intervention recipients (50.0%), intervention deliverers (28.0%), or both (22.0%). Few studies (26.0%) reported on the reliability or validity of methods used. Receipt is infrequently addressed in health research and improvements to methods of assessment and reporting are required.

2016-01-01

A study of disability among the indigenous Sami people in Norway presented a number of ethical and methodological challenges rarely addressed in the literature. The main study was designed to examine and understand the everyday life, transitions between life stages and democratic participation of Norwegian Sami people experiencing disability. Hence, the purpose of this article is to increase the understanding of possible ethical and methodological issues in research within this field. The article describes and discusses ethical and methodological issues that arose when conducting our study and identifies some strategies for addressing issues like these. The ethical and methodological issues addressed in the article are based on a qualitative study among indigenous Norwegian Sami people experiencing disability. The data in this study were collected through 31 semi-structured in-depth interviews with altogether 24 Sami people experiencing disability and 13 next of kin of Sami people experiencing disability (8 mothers, 2 fathers, 2 sister and 1 guardian). The researchers identified 4 main areas of ethical and methodological issues. We present these issues chronologically as they emerged in the research process: 1) concept of knowledge when designing the study, 2) gaining access, 3) data collection and 4) analysis and accountability. The knowledge generated from this study has the potential to benefit future health research, specifically of Norwegian Sami people experiencing disability, as well as health research concerning indigenous people in general, providing scientific-based insight into important ethical and methodological issues in research with indigenous people experiencing disability.

A phenomenographic study of the ability to address complex socio-technical systems via variation theory

NASA Astrophysics Data System (ADS)

Mendoza Garcia, John A.

Sometimes engineers fail when addressing the inherent complexity of socio-technical systems because they lack the ability to address the complexity of socio-technical systems. Teaching undergraduate engineering students how to address complex socio-technical systems, has been an educational endeavor at different levels ranging from kindergarten to post-graduate education. The literature presents different pedagogical strategies and content to reach this goal. However, there are no existing empirically-based assessments guided by a learning theory. This may be because at the same time explanations of how the skill is developed are scarce. My study bridges this gap, and I propose a developmental path for the ability to address the complex socio-technical systems via Variation Theory, and according to the conceptual framework provided by Variation Theory, my research question was "What are the various ways in which engineers address complex socio-technical systems?" I chose the research approach of phenomenography to answer my research question. I also chose to use a blended approach, Marton's approach for finding the dimensions of variation, and the developmental approach (Australian) for finding a hierarchical relationship between the dimensions. Accordingly, I recruited 25 participants with different levels of experience with addressing complex socio-technical systems and asked them all to address the same two tasks: A design of a system for a county, and a case study in a manufacturing firm. My outcome space is a nona-dimensional (nine) developmental path for the ability to address the complexity in socio-technical systems, and I propose 9 different ways of experiencing the complexity of a socio-technical system. The findings of this study suggest that the critical aspects that are needed to address the complexity of socio-technical systems are: being aware of the use of models, the ecosystem around, start recognizing different boundaries, being aware of time as a factor, recognizing the part-whole relationships, make effort in tailoring a solution that responds to stakeholders' needs, find the right problem, giving voice to others, and finally be aware of the need to iterate.

Health-risk behaviors among high school athletes and preventive services provided during sports physicals.

PubMed

Johnson, Karen E; McRee, Annie-Laurie

2015-01-01

Preparticipation examinations (PPEs), or sports physicals, present opportunities for health care providers to identify and discuss common adolescent health-risk behaviors. We sought to examine the prevalence of health-risk behaviors among high school athletes and the proportion of providers who address these behaviors during PPEs. For this descriptive study we used data from two statewide surveys: a survey of adolescents (n = 46,492) and a survey of nurse practitioners and physicians (n = 561). The most prevalent risk behaviors reported by student athletes were low levels of physical activity (70%), bullying perpetration (41%), and alcohol use (41%). Most providers (≥75%) addressed many common risk behaviors during PPEs but fewer addressed bullying, violence, and prescription drug use. Topics discussed differed by provider type and patient population. Many providers addressed critical threats to adolescent health during PPEs, but findings suggest potential disconnects between topics addressed during PPEs and behaviors of athletes.

A review on remote monitoring technology applied to implantable electronic cardiovascular devices.

PubMed

Costa, Paulo Dias; Rodrigues, Pedro Pereira; Reis, António Hipólito; Costa-Pereira, Altamiro

2010-12-01

Implantable electronic cardiovascular devices (IECD) include a broad spectrum of devices that have the ability to maintain rhythm, provide cardiac resynchronization therapy, and/or prevent sudden cardiac death. The incidence of bradyarrhythmias and other cardiac problems led to a broader use of IECD, which turned traditional follow-up into an extremely heavy burden for healthcare systems to support. Our aim was to assess the impact of remote monitoring on the follow-up of patients with IECD. We performed a review through PubMed using a specific query. The paper selection process included a three-step approach in which title, abstract, and cross-references were analyzed. Studies were then selected using previously defined inclusion criteria and analyzed according to the country of origin of the study, year, and journal of publication; type of study; and main issues covered. Twenty articles were included in this review. Eighty percent of the selected papers addressed clinical issues, from which 94% referred clinical events identification, clinical stability, time savings, or physician satisfaction as advantages, whereas 38% referred disadvantages that included both legal and technical issues. Forty-five percent of the papers referred patient issues, from which 89% presented advantages, focusing on patient acceptance/satisfaction, and patient time-savings. The main downsides were technical issues but patient privacy was also addressed. All the papers dealing with economic issues (20%) referred both advantages and disadvantages equally. Remote monitoring is presently a safe technology, widely accepted by patients and physicians, for its convenience, reassurance, and diagnostic potential. This review summarizes the principles of remote IECD monitoring presenting the current state-of-the-art. Patient safety and device interaction, applicability of current technology, and limitations of remote IECD monitoring are also addressed. The use of remote monitor should consider the selection of patients, the type of disease, and centers' availability to receive, interpret and respond to device alerts. Before remote IECD monitoring can be routinely used, technical, procedure, and ethical/legal issues should be addressed.

Thor, Der; Xiao, Nan; Zheng, Meixun; Ma, Ruidan; Yu, Xiao Xi

2017-12-01

Student presentations had been widely implemented across content areas, including health sciences education. However, due to various limitations, small-group student presentations in the classroom may not reach their full potential for student learning. To address challenges with presentations in the classroom, we redesigned the assignment by having students present and discuss online using VoiceThread, a cloud-based presentation and discussion tool. First-year students pursuing a Doctor of Dental Surgery degree were assigned into small groups to present physiology content and to discuss that content online. This assignment was similar to traditional student classroom presentations, with the exception that the entire assignment was conducted online. The primary purpose of this exploratory study was to investigate the impact of the online format on the discussion quality. Another purpose of the study was to examine students' perceptions of using VoiceThread for presenting and learning, as well as the online interactions between the presenter and audience. Students posted a higher number of questions and comments than required by the assignment. The questions from students were also higher level questions, and the answers to these questions were more thorough compared with what we had previously observed in classroom presentations. The survey results showed that students preferred using VoiceThread for presenting, learning from other presentations, and discussing presentation content over performing this process in the classroom. Preliminary findings suggested that having dental students make presentations and hold discussions online might help address the challenges of student presentations in the classroom.

New perspectives on evolutionary medicine: the relevance of microevolution for human health and disease

PubMed Central

2013-01-01

Evolutionary medicine (EM) is a growing field focusing on the evolutionary basis of human diseases and their changes through time. To date, the majority of EM studies have used pure theories of hominin macroevolution to explain the present-day state of human health. Here, we propose a different approach by addressing more empirical and health-oriented research concerning past, current and future microevolutionary changes of human structure, functions and pathologies. Studying generation-to-generation changes of human morphology that occurred in historical times, and still occur in present-day populations under the forces of evolution, helps to explain medical conditions and warns clinicians that their current practices may influence future humans. Also, analyzing historic tissue specimens such as mummies is crucial in order to address the molecular evolution of pathogens, of the human genome, and their coadaptations. PMID:23627943

"Slow food" post-qualitative research in psychology: old craft skills in new disguise?

PubMed

Demuth, Carolin

2015-06-01

The present paper addresses several aspects discussed in the special issue on the future of qualitative research in psychology. Particularly, it asks whether in light of the overhomogenization of the term "qualitative methods" researchers actually can still assume that they talk about the same thing when using this terminology. In addressing the topic of what constitutes the object of psychological research and what accordingly could be a genuinely psychological qualitative research it acknowledges the need to return to the study of persons' unique experience. In light of the risk of "McDonaldization" in present qualitative research, it argues that we need to return to learning research methods as craft skills. It will then give an outlook on how recent developments in discursive and narrative psychology offer a fruitful avenue for studying unique psychological experience as people manage to 'move on' in a material world and in irreversible time.

Parent perspectives and reasons for lower urgency paediatric presentations to emergency departments.

PubMed

Freed, Gary L; Allen, Amy R; Turbitt, Erin; Nicolas, Caroline; Oakley, Ed

2016-04-01

The age band with, by far, the greatest number of ED presentations is children 0-4 years, with other paediatric age bands also among the highest. As the majority of these presentations are for lower urgency conditions, we sought to determine why parents seek ED care for their child for lower urgency conditions. A survey study of 1150 parents or guardians of children with lower urgency conditions (triage category 4 or 5) presenting to the EDs of three public general and one paediatric specialty hospital in metropolitan Melbourne. Fewer than half of parents (43%) attempted to make an appointment with a general practitioner (GP) for their child prior to presenting to the ED. Two-thirds of those who did contact a GP were instructed by their GP to go to the ED for their lower urgency condition. Few attempted to contact a nurse telephone triage service or after-hours GP service. The current magnitude and the growth of lower urgency paediatric ED presentations is a strain on the health care system. Efforts to educate parents regarding the suitability and availability of GP appointments can be the cornerstone of an initial strategy to address this issue. However, efforts to address the high rates of GP referral to EDs for low urgency presentations will be more vexing to develop, yet no less important. They will require addressing fundamental issues in both current GP care for children and the training of GP registrars. © 2016 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

“Extra Oomph:” Addressing Housing Disparities through Medical Legal Partnership Interventions

PubMed Central

Hernández, Diana

2016-01-01

Low-income households face common and chronic housing problems that have known health risks and legal remedies. The Medical Legal Partnership (MLP) program presents a unique opportunity to address housing problems and improve patient health through legal assistance offered in clinical settings. Drawn from in-depth interviews with 72 patients, this study investigated the outcomes of MLP interventions and compares results to similarly disadvantaged participants with no access to MLP services. Results indicate that participants in the MLP group were more likely to achieve adequate, affordable and stable housing than those in the comparison group. Study findings suggest that providing access to legal services in the healthcare setting can effectively address widespread health disparities rooted in problematic housing. Implications for policy and scalability are discussed with the conclusion that MLPs can shift professionals’ consciousness as they work to improve housing and health trajectories for indigent groups using legal approaches.

Teacher knowledge, instructional expertise, and the development of reading proficiency.

PubMed

Reid Lyon, G; Weiser, Beverly

2009-01-01

Teacher knowledge and instructional expertise have been found in correlational and pre- and posttest studies to be related to student reading achievement. This article summarizes data presented in this special issue and additional research to address four questions: (a) What do expert reading teachers know? (b) Why do teachers need to acquire this knowledge? (c) Do teachers believe they have this knowledge? and (d) Are teachers being adequately prepared to teach reading? Well-designed studies relevant to this topic have been sparse with a noticeable lack of attention given to identifying specific causal links between teacher knowledge, teaching expertise, and student reading achievement. Until the appropriate research designs and methodologies are applied to address the question of causal effects, conclusions about the specific content that teachers must know and the instructional practices that are most beneficial in presenting this content are preliminary at best. Future studies of the effect of essential reading content knowledge must be extended beyond word-level skills to vocabulary, reading comprehension, and writing.

2013-01-01

In the genomic age, the challenges presented by various inherited conditions present a compelling argument for an interdisciplinary model of care. Cardiac arrhythmias with a genetic basis, such as long QT syndrome, require clinicians with expertise in many specialties to address the complex genetic, psychological, ethical and medical issues involved in treatment. The Montefiore-Einstein Center for CardioGenetics has been established to provide personalized, interdisciplinary care for families with a history of sudden cardiac death or an acute cardiac event. Four vignettes of patient care are presented to illustrate the unique capacity of an interdisciplinary model to address genetic, psychological, ethical and medical issues. Because interdisciplinary clinics facilitate collaboration among multiple specialties, they allow for individualized, comprehensive care to be delivered to families who experience complex inherited medical conditions. As the genetic basis of many complex conditions is discovered, the advantages of an interdisciplinary approach for delivering personalized medicine will become more evident.

2013-01-08

A stream prefetch engine performs data retrieval in a parallel computing system. The engine receives a load request from at least one processor. The engine evaluates whether a first memory address requested in the load request is present and valid in a table. The engine checks whether there exists valid data corresponding to the first memory address in an array if the first memory address is present and valid in the table. The engine increments a prefetching depth of a first stream that the first memory address belongs to and fetching a cache line associated with the first memory address from the at least one cache memory device if there is not yet valid data corresponding to the first memory address in the array. The engine determines whether prefetching of additional data is needed for the first stream within its prefetching depth. The engine prefetches the additional data if the prefetching is needed.

1988-01-01

The next generation of computer systems are studied by examining the processes and methodologies. The present generation is ok for small projects, but not so good for large projects. They are not good for addressing the iterative nature of requirements, resolution, and implementation. They do not address complexity issues of requirements stabilization. They do not explicitly address reuse opportunities, and they do not help with people shortages. Therefore, there is a need to define and automate improved software engineering processes. Some help may be gained by reuse and prototyping, which are two sides of the same coin. Reuse library parts are used to generate good approximations to desired solutions, i.e., prototypes. And rapid prototype composition implies use of preexistent parts, i.e., reusable parts.

Evaluation of iconic versus F-map microburst displays

NASA Technical Reports Server (NTRS)

Salzberger, Mark; Hansman, R. John; Wanke, Craig

1994-01-01

Previous studies have shown graphical presentation methods of hazardous wind shear to be superior to textual or audible warnings alone. Positional information and the strength of the hazard were observed to be and were cited by pilots as the most important factors in a display. In this experiment the use of the three different graphical presentations of hazardous wind shear are examined. Airborne predictive detectors of wind shear enable the dissemination of varying levels of information. The effectiveness of iconic and mapping display modes of different complexities are addressed through simulation and analysis. Different positional and time-varying situations are presented in a 'part-task' Boeing 767 simulator using data from actual microburst events. Experienced airline pilots fly approach profiles using both iconic and F-map wind shear alerting displays. Microburst accompanied each event is also shown to the pilot. Mapping display types are expected to be found exceptionally efficient at conveying location comparison information while iconic displays simplify the threat recognition process. Preliminary results from the simulator study are presented. Recommendations concerning the suitability of multilevel iconic and mapping displays are made. Situational problems with current display prototypes are also addressed.

Best Practices for Unstructured Grid Shock-Fitting

NASA Technical Reports Server (NTRS)

McCoud, Peter L.

2017-01-01

Unstructured grid solvers have well-known issues predicting surface heat fluxes when strong shocks are present. Various efforts have been made to address the underlying numerical issues that cause the erroneous predictions. The present work addresses some of the shortcomings of unstructured grid solvers, not by addressing the numerics, but by applying structured grid best practices to unstructured grids. A methodology for robust shock detection and shock-fitting is outlined and applied to production-relevant cases. Results

In systematic reviews of studies of patients' values and preferences, the objective of the study was to summarize items and domains authors have identified when considering the risk of bias (RoB) associated with primary studies. We conducted a systematic survey of systematic reviews of patients' values and preference studies. Our search included three databases (MEDLINE, EMBASE, and PsycINFO) from their inception to August 2015. We conducted duplicate data extraction, focusing on items that authors used to address RoB in the primary studies included in their reviews and the associated underlying domains, and summarized criteria in descriptive tables. We identified 42 eligible systematic reviews that addressed 23 items relevant to RoB and grouped the items into 7 domains: appropriate administration of instrument; instrument choice; instrument-described health state presentation; choice of participants group; description, analysis, and presentation of methods and results; patient understanding; and subgroup analysis. The items and domains identified provide insight into issues of RoB in patients' values and preference studies and establish the basis for an instrument to assess RoB in such studies.

Diazonium-protein adducts for graphite electrode microarrays modification: direct and addressed electrochemical immobilization.

PubMed

Corgier, Benjamin P; Marquette, Christophe A; Blum, Loïc J

2005-12-28

Diazonium cation electrodeposition was investigated for the direct and electro-addressed immobilization of proteins. For the first time, this reaction was triggered directly onto diazonium-modified proteins. Screen-printed (SP) graphite electrode microarrays were studied as active support for this immobilization. A 10-microelectrode (eight working electrodes, 0.2 mm2 each; one reference; and one auxiliary) setup was used to study the addressing possibilities of the method. These electrode microarrays were shown to be able to covalently graft diazonium cations through electrochemical reduction. Cyclic voltammetry and X-ray photoelectron spectroscopy were used to characterize the electrochemical grafting onto our SP graphite surface and suggested that a diazonium monolayer was deposited. Rabbit and human immunoglobulins (IgGs) were then chemically coupled to an aniline derivative (4-carboxymethylaniline), followed by diazotation to form an aryl diazonium function available for the electrodeposition. These modified proteins were both successfully electro-addressed at the surface of the graphite electrodes without cross-talk or interference. The immuno-biochip obtained using this novel approach enabled the specific detection of anti-rabbit IgG antibodies with a detection limit of 50 fmol of protein. A promising strategy to immobilize markedly different biological entities was then presented, providing an excellent spatial specificity of the electro-addressing.

Enriching the Research Experiences for Undergraduates in Geoscience Through Student Feedback

NASA Astrophysics Data System (ADS)

Sears, R. F.; Bank, C. G.

2014-12-01

Research Experiences for Undergraduates (REU) allow students to work alongside professionals while they conduct scientific research and offer excellent opportunities to expose students to the practical components of their university education. Indeed, anecdotal evidence shows that a well-planned REU builds teamwork skills, provides a deeper understanding of the science learned in the classroom, and allows students to experience the various stages of science and thus consider wider career options. However, such evidence is difficult to measure. In this presentation we will present preliminary results from a survey of 2nd and 3rd year students who have been engaged in separate interdisciplinary projects (a geophysical survey in South Africa to assist archaeologists, and a forensic study in collaboration with the provincial police). Our before and after surveys address criteria such as students' understanding of scientific methodology, familiarity with the topic and tools for the research, expectations of the study and of themselves, and logistics of doing science. It is our hope that the student voices we present will help REU program coordinators to address limitations and establish best practices to provide the richest possible learning experience.

Technical and conceptual considerations for using animated stimuli in studies of animal behavior.

Rapid technical advances in the field of computer animation (CA) and virtual reality (VR) have opened new avenues in animal behavior research. Animated stimuli are powerful tools as they offer standardization, repeatability, and complete control over the stimulus presented, thereby "reducing" and "replacing" the animals used, and "refining" the experimental design in line with the 3Rs. However, appropriate use of these technologies raises conceptual and technical questions. In this review, we offer guidelines for common technical and conceptual considerations related to the use of animated stimuli in animal behavior research. Following the steps required to create an animated stimulus, we discuss (I) the creation, (II) the presentation, and (III) the validation of CAs and VRs. Although our review is geared toward computer-graphically designed stimuli, considerations on presentation and validation also apply to video playbacks. CA and VR allow both new behavioral questions to be addressed and existing questions to be addressed in new ways, thus we expect a rich future for these methods in both ultimate and proximate studies of animal behavior.

Frame, M.T.; Cotter, G.; Zolly, L.; Little, J.

2002-01-01

Whether your vantage point is that of an office window or a national park, your view undoubtedly encompasses a rich diversity of life forms, all carefully studied or managed by some scientist, resource manager, or planner. A few simple calculations - the number of species, their interrelationships, and the many researchers studying them - and you can easily see the tremendous challenges that the resulting biological data presents to the information and computer science communities. Biological information varies in format and content: it may pertain to a particular species or an entire ecosystem; it can contain land use characteristics, and geospatially referenced information. The complexity and uniqueness of each individual species or ecosystem do not easily lend themselves to today's computer science tools and applications. To address the challenges that the biological enterprise presents, the National Biological Information Infrastructure (NBII) (http://www.nbii.gov) was established in 1993 on the recommendation of the National Research Council (National Research Council 1993). The NBII is designed to address these issues on a national scale, and through international partnerships. This paper discusses current information and computer science efforts within the National Biological Information Infrastructure Program, and future computer science research endeavors that are needed to address the ever-growing issues related to our nation's biological concerns. ?? 2003 by The Haworth Press, Inc.

Simultaneous Multiple MS Binding Assays Addressing D1 and D2 Dopamine Receptors.

PubMed

Schuller, Marion; Höfner, Georg; Wanner, Klaus T

2017-10-09

MS Binding Assays are a label-free alternative to radioligand binding assays. They provide basically the same capabilities as the latter, but use a non-labeled reporter ligand instead of a radioligand. In contrast to radioligand binding assays, MS Binding Assays offer-owing to the selectivity of mass spectrometric detection-the opportunity to monitor the binding of different reporter ligands at different targets simultaneously. The present study shows a proof of concept for this strategy as exemplified for MS Binding Assays selectively addressing D 1 and D 2 dopamine receptors in a single binding experiment. A highly sensitive, rapid and robust LC-ESI-MS/MS quantification method capable of quantifying both SCH23390 and raclopride, selectively addressing D 1 and D 2 receptors, respectively, was established and validated for this purpose. Based thereon, simultaneous saturation and competition experiments with SCH23390 and raclopride in the presence of both D 1 and D 2 receptors were performed and analyzed by LC-MS/MS within a single chromatographic cycle. The present study thus demonstrates the feasibility of this strategy and the high versatility of MS Binding Assays that appears to surpass that common for conventional radioligand binding assays. © 2017 Wiley-VCH Verlag GmbH & Co.

Nutritional issues for older adults: addressing degenerative ageing with long-term studies.

PubMed

de Groot, Lisette C P G M

2016-05-01

The ageing process is influenced by a variety of factors, including extrinsic, malleable lifestyle variables. The present paper deals with the epidemiological evidence for the role of dietary patterns and key nutritional concerns in relation to survival and ageing-related disorders that present themselves in later life. Healthful dietary patterns appear to be most relevant in old age. Specific nutritional concerns are related to vitamin D, vitamin B12 and protein malnutrition. An important challenge to further expand the knowledge base is currently addressed by the NuAge project, acknowledging the complexity of the ageing process and integrating different dimensions of research into human healthy ageing. In the meantime, reversing poor adherence to existing guidelines for a healthy diet remains a first challenge in public health nutritional practices.

A systematic review and checklist presenting the main challenges for health economic modeling in personalized medicine: towards implementing patient-level models.

PubMed

Degeling, Koen; Koffijberg, Hendrik; IJzerman, Maarten J

2017-02-01

The ongoing development of genomic medicine and the use of molecular and imaging markers in personalized medicine (PM) has arguably challenged the field of health economic modeling (HEM). This study aims to provide detailed insights into the current status of HEM in PM, in order to identify if and how modeling methods are used to address the challenges described in literature. Areas covered: A review was performed on studies that simulate health economic outcomes for personalized clinical pathways. Decision tree modeling and Markov modeling were the most observed methods. Not all identified challenges were frequently found, challenges regarding companion diagnostics, diagnostic performance, and evidence gaps were most often found. However, the extent to which challenges were addressed varied considerably between studies. Expert commentary: Challenges for HEM in PM are not yet routinely addressed which may indicate that either (1) their impact is less severe than expected, (2) they are hard to address and therefore not managed appropriately, or (3) HEM in PM is still in an early stage. As evidence on the impact of these challenges is still lacking, we believe that more concrete examples are needed to illustrate the identified challenges and to demonstrate methods to handle them.

Addressing the implementation gap in global road safety: exploring features of an effective response and introducing a 10-country program.

PubMed

Hyder, Adnan A; Allen, Katharine A; Di Pietro, Gayle; Adriazola, Claudia A; Sobel, Rochelle; Larson, Kelly; Peden, Margie

2012-06-01

Yearly, more than 1.2 million people are killed by road traffic injuries (RTIs) around the globe, and another 20 to 50 million are injured. The global burden of RTIs is predicted to rise. We explored the need for concerted action for global road safety and propose characteristics of an effective response to the gap in addressing RTIs. We propose that a successful response includes domains such as strong political will, capacity building, use of evidence-based interventions, rigorous evaluation, increased global funding, multisectoral action, and sustainability. We also present a case study of the global Road Safety in 10 Countries project, which is a new, 5-year, multipartner initiative to address the burden of RTIs in 10 low- and middle-income countries.

Human Research Program Human Health Countermeasures Element Sensorimotor Risk Standing Review Panel (SRP) Final Report

NASA Technical Reports Server (NTRS)

Peterson, Barry

2009-01-01

The Sensorimotor Risk Standing Review Panel (SRP) met at the NASA Johnson Space Center on October 4-6, 2009 to discuss the areas of future research targeted by the Human Health Countermeasures (HHC) Element of the Human Research Program (HRP). Using evidence-based knowledge as a background for risks, NASA had identified gaps in knowledge to address those risks. Ongoing and proposed tasks were presented to address the gaps. The charge to the Sensorimotor Risk SRP was to review the gaps, evaluate whether the tasks addressed these gaps and to make recommendations to NASA s HRP Science Management Office regarding the SRP's review. The SRP was requested to evaluate the practicality of the proposed efforts in light of the realistic demands placed on the HRP. In short, all tasks presented in the Integrated Research Plan (IRP) should address specific risks related to the challenges faced by the astronauts as a result of prolonged exposure to microgravity. All tasks proposed to fill the gaps in knowledge should provide applied, translational data necessary to address the specific risks. Several presentations were made to the SRP during the site visit and the SRP spent sufficient time to address the panel charge, either as a group or in separate sessions. The SRP made a final debriefing to the HRP Program Scientist. Taking the evidence and the risk as givens, the SRP reached the following conclusions: 1) the panel is very supportive of and endorses the present activities of the Sensorimotor Risk; and the panel is likewise supportive of the gaps and associated tasks in the IRP; 2) overall, the tasks addressed the gaps in the IRP; 3) there were some gaps and tasks that merit further enhancement and some new gaps/tasks that the SRP recommends.

A Mission Concept to Study Multigenerational Mammalian Reproduction in Partial Gravity

NASA Technical Reports Server (NTRS)

Rodgers, Erica M.; Simon, Matthew A.; Chai, Patrick R.; Neilan, James H.; Stillwagen, Fred H.; Williams, Phillip A.; Lewis, Weston

2016-01-01

A team at NASA Langley Research Center conducted a study during which a conceptual space mission was designed. In this study, rodents are used as human analogs to gather biological and systems data in a relevant environment applicable to future settlements on Mars. The mission concept uniquely addresses the combined effects of long-durations (one-year or greater), autonomous and robotic operations, and biological responses to partial gravity with an emphasis on reproduction. The objectives of this study were to 1) understand challenges associated with designing an artificial gravity habitat that supports the reproduction and maturation of a large animal colony, 2) identify mission architectures and operational concepts to transport and maintain such a facility, and 3) identify fundamental science considerations for mammalian reproduction studies to inform vehicle design. A model demonstration unit was developed to visualize and test certain design concepts that resulted from these considerations. Three versions of this demonstration unit were built over the course of the study, each taking into account lessons learned from the previous version. This paper presents the updated baseline mission and spacecraft design concepts to achieve these objectives, with a specific emphasis on updates since publication in previous works. Analyses of the integrated system trades among the elements which make up the conceptual vehicle are described to address overall feasibility and identify potential integrated design opportunities. The latest iteration of the habitat robotics design and a conceptual design example for autonomous care of crew and systems are also presented. Finally, the conclusion of this conceptual design study, necessary future analyses to enable such a facility, and comments upon other applications of a similar exploration-focused research facilities are addressed.

The Swedish study circle--possibilities for application to health education in the United States.

PubMed

Strombeck, R

1991-03-01

There has been a growing recognition over the past decade of the need to broaden the focus of health promotion by placing greater emphasis on the social context in which individual behavior change interventions occur. As a result, health educators are being required to look for innovative pedagogical methods to address this broader focus. A model of education that is used extensively in Sweden and that takes a broader approach to health matters is the study circle. Because of its simple, flexible structure and its capacity to address lifestyle as well as social and environmental factors, the study circle could serve as a model for health education efforts undertaken in the United States. The first part of this article presents an overview of the literature from the field of public health that calls for a broader concept of health promotion. The second part of the article looks at the principles and concepts of the study circle. The role of the study circle in health promotion is discussed and use of the method is illustrated in three different case examples. In addition, possibilities for application of the model to health education in the United States are also addressed.

Gain versus loss framing in adherence-promoting communication targeting patients with chronic diseases: the moderating effect of individual time perspective.

PubMed

Zhao, Xiaoquan; Villagran, Melinda M; Kreps, Gary L; McHorney, Colleen

2012-01-01

This study investigated the joint effect of message framing and time perspective in adherence-promoting communication targeting patients with chronic diseases. Based on previous framing and time perspective research, it was hypothesized that the gain frame would show an advantage over the loss frame among future-oriented patients; for present-oriented patients, it was hypothesized that the framing effect would be relatively indistinct. In total, 1,108 currently nonadherent patients with chronic disease participated in an experiment where they were randomly assigned to either gain- or loss-framed messages addressing key beliefs underlying their nonadherence or a no-message control condition. Intention and attitude regarding future adherence as well as message perceptions were measured after message presentation. Results of this study generally supported the hypotheses. Message topics-whether the messages addressed patients' perceived need for medications or concerns about side effects-did not moderate the effect of framing or the interaction between framing and time perspective. Theoretical and practical implications are discussed.

Transportation node space station conceptual design

NASA Technical Reports Server (NTRS)

1988-01-01

A number of recent studies have addressed the problem of a transportation node space station. How things would change or what addition facilities would be needed to support a major lunar or Mars initiative is a much often asked question. The support of a lunar base, requiring stacks on the order of 200 metric tons each to land 25 m tons on the lunar surface with reusable vehicles is addressed. The problem of maintaining and reusing large single stage Orbit Transfer Vehicles (OTVs) and single stage lander/launchers in space are examined. The required people and equipment needed, to maintain these vehicles are only vaguely known at present. The people and equipment needed depend on how well the OTV and lander/launcher can be designed for easy reuse. Since the OTV and lander/launcher are only conceptually defined at present, the real maintenance and refurbishment requirements are unobtainable. An estimate of what is needed, based on previous studies and obvious requirements was therefore made. An attempt was made to err on the conservative side.

To achieve the study objective, two major tasks are accomplished, knowledge synthesis and algorithmic computational methodology. The knowledge synthesis task is designed to capture "what is known" and to outline the gaps in knowledge from ENMs risk perspective. The algorithmic computational methodology is geared toward the provision of decisions and an understanding of the risks of ENMs along different endpoints for the constituents of the SEE complex adaptive system. The approach presented herein allows for addressing the formidable task of assessing the implications and risks of exposure to ENMs, with the long term goal to build a decision-support system to guide key stakeholders in the SEE system towards building sustainable ENMs and nano-enabled products.

Many organizations face high consequence safety situations where unwanted stimuli due to accidents, catastrophes, or inadvertent human actions can cause disasters. In order to improve interaction among such organizations and to build on each others` experience, preventive approaches, and assessment techniques, the High Consequence Operations Safety Symposium was held July 12--14, 1994 at Sandia National Laboratories, Albuquerque, New Mexico. The symposium was conceived by Dick Schwoebel, Director of the SNL Surety Assessment Center. Stan Spray, Manager of the SNL System Studies Department, planned strategy and made many of the decisions necessary to bring the concept to fruition on a shortmore » time scale. Angela Campos and about 60 people worked on the nearly limitless implementation and administrative details. The initial symposium (future symposia are planned) was structured around 21 plenary presentations in five methodology-oriented sessions, along with a welcome address, a keynote address, and a banquet address. Poster papers addressing the individual session themes were available before and after the plenary sessions and during breaks.« less

Best Practices for Unstructured Grid Shock Fitting

NASA Technical Reports Server (NTRS)

McCloud, Peter L.

2017-01-01

Unstructured grid solvers have well-known issues predicting surface heat fluxes when strong shocks are present. Various efforts have been made to address the underlying numerical issues that cause the erroneous predictions. The present work addresses some of the shortcomings of unstructured grid solvers, not by addressing the numerics, but by applying structured grid best practices to unstructured grids. A methodology for robust shock detection and shock fitting is outlined and applied to production relevant cases. Results achieved by using the Loci-CHEM Computational Fluid Dynamics solver are provided.

Health in All Policies in South Australia—Did It Promote and Enact an Equity Perspective?

PubMed Central

Harris, Elizabeth; Baum, Fran; Delany-Crowe, Toni; MacDougall, Colin

2017-01-01

Mobilising cross-sectoral action is helpful in addressing the range of social determinants that contribute to health inequities. The South Australian Health in All Policies (SA HiAP) approach was implemented from 2007 to stimulate cross-sector policy activity to address the social determinants of health to improve population wellbeing and reduce health inequities. This paper presents selected findings from a five year multi-methods research study of the SA HiAP approach and draws on data collected during interviews, observation, case studies, and document analysis. The analysis shows that SA HiAP had dual goals of facilitating joined-up government for co-benefits (process focus); and addressing social determinants of health and inequities through cross-sectoral policy activity (outcomes focus). Government agencies readily understood HiAP as providing tools for improving the process of intersectoral policy development, while the more distal outcome-focused intent of improving equity was not well understood and gained less traction. While some early rhetorical support existed for progressing an equity agenda through SA HiAP, subsequent economic pressures resulted in the government narrowing its priorities to economic goals. The paper concludes that SA HiAP’s initial intentions to address equity were only partially enacted and little was done to reduce inequities. Emerging opportunities in SA, and internationally, including the UN Sustainable Development Goals, may revive interest in addressing equity. PMID:29068400

The parent-child-therapist alliance: A case study using a strategic approach.

PubMed

Naidu, Thirusha; Behari, Sheethal

2010-06-01

In this paper we present a single case study of a clinical approach that addresses the needs of parents and their children in psychotherapy. The approach begins by addressing the child's and parent's concerns separately at first by establishing strong therapeutic alliances with each, and then proceeds to address the concerns of the parent-child dyad. The basic premise is that the therapeutic alliance is the central element to successful outcomes in psychotherapy. The nature of alliance-building and its associated methods and techniques have been extensively considered for adult therapy. However, there is considerably less written on the therapeutic alliance with children and adolescents in the context of family interventions. We briefly examine some theoretical dimensions and applications of the therapeutic alliance in psychotherapy with children/adolescents and their parents. A three-phase alliance-building psychotherapy strategy, founded on the idea that each therapeutic relationship warrants an effective working alliance, is proposed. The case of a single mother and her adolescent daughter is employed to illustrate the strategy.

Negative workplace behaviours: an ethical dilemma for nurse managers.

PubMed

Lindy, Cheryl; Schaefer, Florence

2010-04-01

To discover nurse managers' perception of negative workplace behaviours (bullying) encountered by staff on their unit. Background Negative workplace behaviour is a worldwide phenomenon happening in all types of work settings. Absent from the literature were studies specific to the nurse managers' perception on this topic. A phenomenological qualitative research methodology was used to gain insight into the perceptions of nurse managers about negative workplace behaviours that they have observed or addressed. Nurse Managers described their perceptions of, and experiences pertaining to, instances of negative workplace behaviour. Six themes emerged from the data analysis: 'that's just how she is', 'they just take it', 'a lot of things going on', 'old baggage', 'three sides to a story' and 'a management perspective'. Nurse Managers had observed, experienced and/or had received reports of negative workplace behaviours. While some felt comfortable addressing the behaviour, others experienced ethical dilemmas when trying to treat all fairly. The results of the present study provide guidance for nurse managers to address negative workplace behaviours occurring on their units.

Barriers to disseminating brief CBT for voices from a lived experience and clinician perspective

2017-01-01

Access to psychological therapies continues to be poor for people experiencing psychosis. To address this problem, researchers are developing brief interventions that address the specific symptoms associated with psychosis, i.e., hearing voices. As part of the development work for a brief Cognitive Behaviour Therapy (CBT) intervention for voices we collected qualitative data from people who hear voices (study 1) and clinicians (study 2) on the potential barriers and facilitators to implementation and engagement. Thematic analysis of the responses from both groups revealed a number of anticipated barriers to implementation and engagement. Both groups believed the presenting problem (voices and psychosis symptoms) may impede engagement. Furthermore clinicians identified a lack of resources to be a barrier to implementation. The only facilitator to engagement was reported by people who hear voices who believed a compassionate, experienced and trustworthy therapist would promote engagement. The results are discussed in relation to how these barriers could be addressed in the context of a brief intervention using CBT techniques. PMID:28575094

Don't forget the siblings: School-aged siblings of children presenting to mental health services show at-risk patterns of attachment.

PubMed

Kozlowska, Kasia; Elliott, Bronwen

2017-04-01

Family therapists understand that children presenting for treatment are often bearers of symptoms signalling relational problems within the family system. Rather than addressing the children's symptoms in isolation, family therapists typically take those relational problems as their starting point in therapy. This study used the School-aged Assessment of Attachment (SAA) to assess the self-protective (attachment) strategies of the siblings of children presenting for psychiatric evaluation and also of the siblings of control children drawn from the normative population. Siblings of children in the clinical group were much more likely than siblings of control children to use at-risk self-protective strategies and to have markers suggestive of unresolved loss or trauma. School-aged siblings were found to use a broad range of strategies, and the pattern of change from first born to later born involved either a reversal of strategy or a shift to a more complex strategy. The study highlights that siblings of children presenting to mental health services are significantly affected by family relational stress. A family systems approach to assessment, one that enquires about the wellbeing of all family members, will ensure that the emotional needs of siblings are also addressed during the therapy process.

Neutrinos remain among the least understood fundamental particles even after decades of study. As we enter the precision era o f neutrino measurements bigger and more sophisticated detectors have emerged. The leading candidate among them is a Liquid Argon Time Projection Chamber (LArTPC ) detector technology due to its bubble-like chamber imaging, superb background rejection and scalability. I t is a perfect candidate that w ill aim to answer the remaining questions of the nature o f neutrino and perhaps our existence. Studying neutrinos with a detector that employs detection via beautiful images o f neutrino interactions can be bothmore » illuminating and surprising. The analysis presented here takes the full advantage of the LArTPC power by exploiting the first topological analysis of charged current muon neutrino p + N p , muon and any number of protons, interactions with the ArgoNeuT LArTPC experiment on an argon target. The results presented here are the first that address the proton multiplicity at the vertex and the proton kinematics. This study also addresses the importance o f nuclear effects in neutrino interactions. Furthermore, the developed here reconstruction techniques present a significant step forward for this technology and can be employed in the future LArTPC detectors.« less

The European Space Agency and other space agencies such as NASA recognize that the question with regard to life beyond Earth in general, and the associated issue of the existence and study of exoplanets in particular, is of paramount importance for the 21(st) century. The new Cosmic Vision science plan, Cosmic Vision 2015-2025, which is built around four major themes, has as its first theme: "What are the conditions for planet formation and the emergence of life?" This main theme is addressed through further questions: 1) How do gas and dust give rise to stars and planets? 2) How will the search for and study of exoplanets eventually lead to the detection of life outside Earth (biomarkers)? 3) How did life in the Solar System arise and evolve? Although ESA has busied itself with these issues since the beginning of the Darwin study in 1996, it has become abundantly clear that, as these topics have evolved, only a very large effort, addressed from the ground and from space with the utilization of different instruments and space missions, can provide the empirical results required for a complete understanding. The good news is that the problems can be addressed and solved within a not-too-distant future. In this short essay, we present the present status of a roadmap related to projects that are related to the key long-term goal of understanding and characterizing exoplanets, in particular Earth-like planets.

2016-01-01

A number of concepts exist regarding how urbanization can be described as a process. Understanding this process that affects billions of people and its future development in a spatial manner is imperative to address related issues such as human quality of life. In the focus of spatially explicit studies on urbanization is typically a city, a particular urban region, an agglomeration. However, gaps remain in spatially explicit global models. This paper addresses that issue by examining the spatial dynamics of urban areas over time, for a full coverage of the world. The presented model identifies past, present and potential future hotspots of urbanization as a function of an urban area's spatial variation and age, whose relation could be depicted both as a proxy and as a path of urban development.

Progress on automated data analysis algorithms for ultrasonic inspection of composites

NASA Astrophysics Data System (ADS)

Aldrin, John C.; Forsyth, David S.; Welter, John T.

2015-03-01

Progress is presented on the development and demonstration of automated data analysis (ADA) software to address the burden in interpreting ultrasonic inspection data for large composite structures. The automated data analysis algorithm is presented in detail, which follows standard procedures for analyzing signals for time-of-flight indications and backwall amplitude dropout. New algorithms have been implemented to reliably identify indications in time-of-flight images near the front and back walls of composite panels. Adaptive call criteria have also been applied to address sensitivity to variation in backwall signal level, panel thickness variation, and internal signal noise. ADA processing results are presented for a variety of test specimens that include inserted materials and discontinuities produced under poor manufacturing conditions. Software tools have been developed to support both ADA algorithm design and certification, producing a statistical evaluation of indication results and false calls using a matching process with predefined truth tables. Parametric studies were performed to evaluate detection and false call results with respect to varying algorithm settings.

Timraz, Shahrazad M; Alhasanat, Dalia I; Albdour, Maha M; Lewin, Linda; Giurgescu, Carmen; Kavanaugh, Karen

2017-02-01

Recruiting minority groups such as Arab Americans (Ar-Am) for research studies has been challenging. To date no studies were found that explicitly addressed challenges to recruit Ar-Am for sensitive research. The purpose of this article is to present the challenges across three pilot studies that involved Ar-Am samples and the strategies that were implemented to overcome these challenges. The challenges faced with conducting studies with Ar-Am included difficulty for participants to express emotions, influence of male/female authority to consent for the study, lack of trust to disclose sensitive information, language barrier, and slow recruitment. Having bilingual female recruiters of Arabic descent, engaging the women's family members in the consent process, and addressing the sensitive topics in culturally appropriate language were effective strategies to overcome these challenges. These strategies might be helpful for other researchers who recruit Ar-Am for sensitive research. Copyright © 2016 Elsevier Inc. All rights reserved.

Verification and Validation of Flight-Critical Systems

NASA Technical Reports Server (NTRS)

Brat, Guillaume

2010-01-01

For the first time in many years, the NASA budget presented to congress calls for a focused effort on the verification and validation (V&V) of complex systems. This is mostly motivated by the results of the VVFCS (V&V of Flight-Critical Systems) study, which should materialize as a a concrete effort under the Aviation Safety program. This talk will present the results of the study, from requirements coming out of discussions with the FAA and the Joint Planning and Development Office (JPDO) to technical plan addressing the issue, and its proposed current and future V&V research agenda, which will be addressed by NASA Ames, Langley, and Dryden as well as external partners through NASA Research Announcements (NRA) calls. This agenda calls for pushing V&V earlier in the life cycle and take advantage of formal methods to increase safety and reduce cost of V&V. I will present the on-going research work (especially the four main technical areas: Safety Assurance, Distributed Systems, Authority and Autonomy, and Software-Intensive Systems), possible extensions, and how VVFCS plans on grounding the research in realistic examples, including an intended V&V test-bench based on an Integrated Modular Avionics (IMA) architecture and hosted by Dryden.

Planning strategies for the avoidance of pitfalls in intervention research.

PubMed

Pruitt, R H; Privette, A B

2001-08-01

With the exception of large clinical trials, few studies in nursing and other social sciences test interventions. The discipline of nursing needs to maintain a full range of research designs for continued knowledge development. Intervention research presents unique opportunities and challenges for the novice as well as the seasoned researcher. Some of these methodological challenges include the complex nature of human subjects and interventions, including many factors that interfere with the study variables. Preliminary studies often reveal challenges that may not always be predicted or reflected in research texts. These challenges may be as important as the study results for success in future research efforts. Difficulties encountered in intervention research and suggested strategies for maintaining the integrity of the study are addressed. These challenges include maintaining an adequate sample size, intervention demands, measuring variables, timing issues, and experiencing unexpected events. Strategies presented include the importance of extensive planning, minimizing subject expectations and rewarding efforts, attention to control group members, incorporating retention strategies, expanding knowledge of variables and the study population, preliminary studies as well as anticipating unexpected events. The need for enhanced communication among nurse researchers, educators and clinicians is addressed. In the current health care arena, nurse researchers must understand organizational dynamics and marketing strategies. Collaborative research efforts can increase the visibility of nursing research as well as funding opportunities.

2016-01-01

Background and aim Adherence to treatment is a critical component of epilepsy management. This study examines whether addressing antiepileptic drug (AED) side effects at every visit is associated with increased patient-reported medication adherence. Patients and methods This study identified 243 adults with epilepsy who were seen at two academic outpatient neurology settings and had at least two visits over a 3-year period. Demographic and clinical characteristics were abstracted. Evidence that AED side effects were addressed was measured through 1) phone interview (patient-reported) and 2) medical records abstraction (physician-documented). Medication adherence was assessed using the validated Morisky Medication Adherence Scale-4. Complete adherence was determined as answering “no” to all questions. Results Sixty-two (25%) patients completed the interviews. Participants and nonparticipants were comparable with respect to demographic and clinical characteristics; however, a smaller proportion of participants had a history of drug-resistant epilepsy than nonparticipants (17.7% vs 30.9%, P=0.04). Among the participants, evidence that AED side effects were addressed was present in 48 (77%) medical records and reported by 51 (82%) patients. Twenty-eight (45%) patients reported complete medication adherence. The most common reason for incomplete adherence was missed medication due to forgetfulness (n=31, 91%). There was no association between addressing AED side effects (neither physician-documented nor patient-reported) and complete medication adherence (P=0.22 and 0.20). Discussion and conclusion Among patients with epilepsy, addressing medication side effects at every visit does not appear to increase patient-reported medication adherence. PMID:27826186

Visual Semiotics & Uncertainty Visualization: An Empirical Study.

PubMed

MacEachren, A M; Roth, R E; O'Brien, J; Li, B; Swingley, D; Gahegan, M

2012-12-01

This paper presents two linked empirical studies focused on uncertainty visualization. The experiments are framed from two conceptual perspectives. First, a typology of uncertainty is used to delineate kinds of uncertainty matched with space, time, and attribute components of data. Second, concepts from visual semiotics are applied to characterize the kind of visual signification that is appropriate for representing those different categories of uncertainty. This framework guided the two experiments reported here. The first addresses representation intuitiveness, considering both visual variables and iconicity of representation. The second addresses relative performance of the most intuitive abstract and iconic representations of uncertainty on a map reading task. Combined results suggest initial guidelines for representing uncertainty and discussion focuses on practical applicability of results.

Research Collaboration in a Communication Rights Campaign: Lessons Learned.

PubMed

Ryan, Charlotte

2018-01-01

In building public support for social change, activists in communities of color routinely approach broader audiences via news media. Communities of color, however, routinely face disparities that limit their access to media including local news media outlets. This lack of access mirrors inequalities in political, social, and economic arenas and can slow public awareness campaigns to address disparities in health, environmental, and other quality-of-life issues. I describe two community-based collaborative action research studies that documented and challenged how local television newscasts underrepresented and misrepresented three communities of color in Boston. The linkage between communication rights and campaigns to address quality-of-life issues is presented, as well as unresolved challenges in the collaborative research process. The study has implications for environmental health campaigns.

Addressing domestic violence in primary care: what the physician needs to know

PubMed Central

Usta, Jinan; Taleb, Rim

2014-01-01

Domestic violence (DV) is quite prevalent and negatively impacts the health and mental wellbeing of those affected. Victims of DV are frequent users of health service, yet they are infrequently recognized. Physicians tend to treat the presenting complaints without addressing the root cause of the problem. Lack of knowledge on adequately managing cases of DV and on appropriate ways to help survivors is commonly presented as a barrier. This article presents the magnitude of the problem of DV in the Arab world, highlights the role of the primary care physician in addressing this problem, and provides practical steps that can guide the clinician in the Arab world in giving a comprehensive and culturally sensitive service to the survivors of DV.

2012-01-01

Yearly, more than 1.2 million people are killed by road traffic injuries (RTIs) around the globe, and another 20 to 50 million are injured. The global burden of RTIs is predicted to rise. We explored the need for concerted action for global road safety and propose characteristics of an effective response to the gap in addressing RTIs. We propose that a successful response includes domains such as strong political will, capacity building, use of evidence-based interventions, rigorous evaluation, increased global funding, multisectoral action, and sustainability. We also present a case study of the global Road Safety in 10 Countries project, which is a new, 5-year, multipartner initiative to address the burden of RTIs in 10 low- and middle-income countries.

Damage and strength of composite materials: Trends, predictions, and challenges

NASA Technical Reports Server (NTRS)

Obrien, T. Kevin

1994-01-01

Research on damage mechanisms and ultimate strength of composite materials relevant to scaling issues will be addressed in this viewgraph presentation. The use of fracture mechanics and Weibull statistics to predict scaling effects for the onset of isolated damage mechanisms will be highlighted. The ability of simple fracture mechanics models to predict trends that are useful in parametric or preliminary designs studies will be reviewed. The limitations of these simple models for complex loading conditions will also be noted. The difficulty in developing generic criteria for the growth of these mechanisms needed in progressive damage models to predict strength will be addressed. A specific example for a problem where failure is a direct consequence of progressive delamination will be explored. A damage threshold/fail-safety concept for addressing composite damage tolerance will be discussed.

2015-09-01

The aim of the present study was to provide descriptive planning data for a hospital-based Aboriginal Health Liaison Officer (AHLO) program, specifically quantifying episodes of care and outcomes within 28 days after discharge. A follow-up study of Aboriginal in-patient hospital episodes was undertaken using person-based linked administrative data from four South Metropolitan hospitals in Perth, Western Australia (2006-11). Outcomes included 28-day deaths, emergency department (ED) presentations and in-patient re-admissions. There were 8041 eligible index admissions among 5113 individuals, with episode volumes increasing by 31% over the study period. Among patients 25 years and older, the highest ranking comorbidities included injury (47%), drug and alcohol disorders (41%), heart disease (40%), infection (40%), mental illness (31%) and diabetes (31%). Most events (96%) ended in a regular discharge. Within 28 days, 24% of events resulted in ED presentations and 20% resulted in hospital readmissions. Emergency readmissions (13%) were twice as likely as booked re-admissions (7%). Stratified analyses showed poorer outcomes for older people, and for emergency and tertiary hospital admissions. Future planning must address the greater service volumes anticipated. The high prevalence of comorbidities requires intensive case management to address case complexity. These data will inform the refinement of the AHLO program to improve in-patient experiences and outcomes.

Epidemiologic study of residential proximity to transmission lines and childhood cancer in California: description of design, epidemiologic methods and study population

PubMed Central

Kheifets, Leeka; Crespi, Catherine M; Hooper, Chris; Oksuzyan, Sona; Cockburn, Myles; Ly, Thomas; Mezei, Gabor

2015-01-01

We conducted a large epidemiologic case-control study in California to examine the association between childhood cancer risk and distance from the home address at birth to the nearest high-voltage overhead transmission line as a replication of the study of Draper et al. in the United Kingdom. We present a detailed description of the study design, methods of case ascertainment, control selection, exposure assessment and data analysis plan. A total of 5788 childhood leukemia cases and 3308 childhood central nervous system cancer cases (included for comparison) and matched controls were available for analysis. Birth and diagnosis addresses of cases and birth addresses of controls were geocoded. Distance from the home to nearby overhead transmission lines was ascertained on the basis of the electric power companies’ geographic information system (GIS) databases, additional Google Earth aerial evaluation and site visits to selected residences. We evaluated distances to power lines up to 2000 m and included consideration of lower voltages (60–69 kV). Distance measures based on GIS and Google Earth evaluation showed close agreement (Pearson correlation >0.99). Our three-tiered approach to exposure assessment allowed us to achieve high specificity, which is crucial for studies of rare diseases with low exposure prevalence. PMID:24045429

Quantum random access memory.

PubMed

Giovannetti, Vittorio; Lloyd, Seth; Maccone, Lorenzo

2008-04-25

A random access memory (RAM) uses n bits to randomly address N=2(n) distinct memory cells. A quantum random access memory (QRAM) uses n qubits to address any quantum superposition of N memory cells. We present an architecture that exponentially reduces the requirements for a memory call: O(logN) switches need be thrown instead of the N used in conventional (classical or quantum) RAM designs. This yields a more robust QRAM algorithm, as it in general requires entanglement among exponentially less gates, and leads to an exponential decrease in the power needed for addressing. A quantum optical implementation is presented.

Analysis of the Digital Evidence Presented in the Yahoo! Case

NASA Astrophysics Data System (ADS)

Kwan, Michael; Chow, Kam-Pui; Lai, Pierre; Law, Frank; Tse, Hayson

The “Yahoo! Case” led to considerable debate about whether or not an IP address is personal data as defined by the Personal Data (Privacy) Ordinance (Chapter 486) of the Laws of Hong Kong. This paper discusses the digital evidence presented in the Yahoo! Case and evaluates the impact of the IP address on the verdict in the case. A Bayesian network is used to quantify the evidentiary strengths of hypotheses in the case and to reason about the evidence. The results demonstrate that the evidence about the IP address was significant to obtaining a conviction in the case.

The possibility that the 'missing mass' in the solar neighborhood may be accounted for by the existence in sufficiently great numbers of such very low mass stars as brown dwarfs, as well as very old dead stars now observable as cold, low-luminosity degenerates, is presently addressed observationally with a search through ESO R Survey plates using a stereocomparator. Attention is given to ESO area 439, where four low-luminosity degenerates have been discovered by the present study.

Address substrates as promising targets for laser histochemical surgery as a nontraditional line in medicine

NASA Astrophysics Data System (ADS)

Piruzyan, L. A.; Mikhailovskiy, Ye. M.; Piruzyan, A. L.

1999-12-01

The priority concept of the laser histochemical surgery as a potentially novel line in medicine is presented. The histochemical stains, selectively coloring some targets (address substrates), that are cells or their biochemical ingredients, sensitize them to the laser irradiation. Such sensitization to laser irradiation by staining turns the colored targets into targets for the laser beam. The action of the irradiation onto its specific targets beats out of the cell its ingredients which participate in a pathology process. In particular, the beating of a stained ferment out of the general stage of biochemical processes characteristic for the pathology interrupts their currence. The laser beam, when beating out its stained targets without any damage of the unstained tissues, acts like a scalpel that cuts off affected tissues not brushing healthy ones. A scheme for testing stains as sensitizers of the `address substrates' to the laser irradiation is presented. As the criterion of the stain sensitization the fact was chosen of absence or weakness of pathomorphologic and biochemical signs of the disease in an experimental model of the pathology irradiated with laser after a stain use, while the pathology signs are present in a control sample. The basis is done for study of the histochemical stains as potential means for the laser histochemical surgery of disseminated sclerosis, mucopolysaccharidosis, hypercholesterolemia, myocardial infarction, cardiosclerosis, caries and parodontosis.

A symposium held at the 50th annual meeting of the Behavioral Pharmacology Society in May 2007 reviewed progress in the human behavioral pharmacology of drug abuse. Studies on drug self-administration in humans are reviewed that assessed reinforcing and subjective effects of drugs of abuse. The close parallels observed between studies in humans and laboratory animals using similar behavioral techniques have broadened our understanding of the complex nature of the pharmacological and behavioral factors controlling drug self-administration. The symposium also addressed the role that individual differences, such as gender, personality, and genotype play in determining the extent of self-administration of illicit drugs in human populations. Knowledge of how these factors influence human drug self-administration has helped validate similar differences observed in laboratory animals. In recognition that drug self-administration is but one of many choices available in the lives of humans, the symposium addressed the ways in which choice behavior can be studied in humans. These choice studies in human drug abusers have opened up new and exciting avenues of research in laboratory animals. Finally, the symposium reviewed behavioral pharmacology studies conducted in drug abuse treatment settings and the therapeutic benefits that have emerged from these studies. PMID:20664330

Neurophysiology Summary

Paloski, William H.

2001-01-01

The terrestrial gravitational field serves as an important orientation reference for human perception and movement, being continually monitored by sensory receptors in the skin, muscles, joints, and vestibular otolith organs. Cues from these graviceptors are used by the brain to estimate spatial orientation and to control balance and movement. Changes in these cues associated with the tonic changes in gravity (gravito-inertial force),during the launch and entry phases of space flight missions result in altered perceptions, degraded motor control performance, and in some cases, "motion" sickness during, and for a period of time after, the g-transitions. In response to these transitions, however, physiological and behavioral response mechanisms are triggered to compensate for altered graviceptor cues and/or to adapt to the new sensory environment. Basic research in the neurophysiology discipline is focused on understanding the characteristic features of and the underlying mechanisms for the normal human response to tonic changes in the gravito-inertial force environment. These studies address fundamental questions regarding the role of graviceptors in orientation and movement in the terrestrial environment, as well as the capacity, specificity, and modes for neural plasticity in the sensory-motor and perceptual systems of the brain. At the 2001 workshop basic research studies were presented addressing: neuroanatomical responses to altered gravity environments, the neural mechanisms for resolving the ambiguity between tilting and translational stimuli in otolith organ sensory input, interactions between the vestibular system and the autonomic nervous system , the roles of haptic and visual cues in spatial orientation, mechanisms for training environment-appropriate sensorimotor responses triggered by environment-specific context cues, and studies of sensori-motor control of posture and locomotion in the terrestrial environment with and without recent exposure to space flight. Building on these basic research studies are more applied studies focused on the development of countermeasures to the untoward neurophysiological responses to space flight. At the 2001 workshop, applied research studies were presented addressing issues related to the use of rotational artificial gravity (centripetal acceleration) as a multisystem (bone, muscle, cardiovascular, and, perhaps, neurovestibular) countermeasure. Also presented was a clinical study reporting on a new rating system for clinical evaluation of postflight functional neurological status.

Selection of optimum locations for locating new facilities and decision regarding capacities at the proposed facilities is a major concern for municipal authorities/managers. The decision as to whether a single facility is preferred over multiple facilities of smaller capacities would vary with varying priorities to cost and associated risks such as environmental or health risk or risk perceived by the society. Currently management of waste streams such as that of computer waste is being done using rudimentary practices and is flourishing as an unorganized sector, mainly as backyard workshops in many cities of developing nations such as India. Uncertainty in the quantification of computer waste generation is another major concern due to the informal setup of present computer waste management scenario. Hence, there is a need to simultaneously address uncertainty in waste generation quantities while analyzing the tradeoffs between cost and associated risks. The present study aimed to address the above-mentioned issues in a multi-time-step, multi-objective decision-support model, which can address multiple objectives of cost, environmental risk, socially perceived risk and health risk, while selecting the optimum configuration of existing and proposed facilities (location and capacities).

Language barriers and qualitative nursing research: methodological considerations.

Squires, A

2008-09-01

This review of the literature synthesizes methodological recommendations for the use of translators and interpreters in cross-language qualitative research. Cross-language qualitative research involves the use of interpreters and translators to mediate a language barrier between researchers and participants. Qualitative nurse researchers successfully address language barriers between themselves and their participants when they systematically plan for how they will use interpreters and translators throughout the research process. Experienced qualitative researchers recognize that translators can generate qualitative data through translation processes and by participating in data analysis. Failure to address language barriers and the methodological challenges they present threatens the credibility, transferability, dependability and confirmability of cross-language qualitative nursing research. Through a synthesis of the cross-language qualitative methods literature, this article reviews the basics of language competence, translator and interpreter qualifications, and roles for each kind of qualitative research approach. Methodological and ethical considerations are also provided. By systematically addressing the methodological challenges cross-language research presents, nurse researchers can produce better evidence for nursing practice and policy making when working across different language groups. Findings from qualitative studies will also accurately represent the experiences of the participants without concern that the meaning was lost in translation.

Background Residency program directors are challenged to effectively teach and assess the Accreditation Council for Graduate Medical Education's (ACGME) 6 competencies. The purpose of this study was to characterize the morbidity and mortality (M&M) conference as a cost-effective and efficient approach for addressing the ACGME competencies through evaluation of resident participation and case diversity. Methods In our modified M&M conference, senior residents submit a weekly list of cases to the conference proctors. The resident presents the case, including a critique of management, using the medical literature. The resident submits a case summary evaluating patient care practices, integrating scientific evidence, and evaluating systemic barriers to care. Completed case summaries are distributed and archived for reference. Results During a 3-year period, 30 residents presented 196 cases. Of these, 37 (19%) directly related to systems-based practice, 20 (10%) involved problems with inadequate communication, and 11 (6%) included issues of professionalism or ethics. All cases involved practice-based learning and medical knowledge. Conclusions The M&M conference addresses the core competencies through resident participation as well as directed analysis of diverse cases. PMID:22379530

2016-06-01

Consumer Medicine Information (CMI) is a brand-specific and standardized source of written medicine information available in Australia for all prescription medicines. Side-effect information is poorly presented in CMI and may not adequately address consumer information needs. To explore consumer opinions on (i) the presentation of side-effect information in existing Australian CMI leaflets and alternative study-designed CMIs and (ii) side-effect risk information and its impact on treatment decision making. Fuzzy trace, affect heuristic, frequency hypothesis and cognitive-experiential theories were applied when revising existing CMI side-effects sections. Together with good information design, functional linguistics and medicine information expertise, alternative ramipril and clopidogrel CMI versions were proposed. Focus groups were then conducted to address the study objectives. Three focus groups (n = 18) were conducted in Sydney, Australia. Mean consumer age was 58 years (range 50-65 years), with equal number of males and females. All consumers preferred the alternative CMIs developed as part of the study, with unequivocal preference for the side-effects presented in a simple tabular format, as it allowed quick and easy access to information. Consumer misunderstandings reflected literacy and numeracy issues inherent in consumer risk appraisal. Many preferred no numerical information and a large proportion preferred natural frequencies. One single method of risk presentation in CMI is unable to cater for all consumers. Consumer misunderstandings are indicative of possible health literacy and numeracy factors that influence consumer risk appraisal, which should be explored further. © 2014 The Authors Health Expectations Published by John Wiley & Sons Ltd.

The State of Research on Communication and Literacy in Deafblindness.

Bruce, Susan M; Nelson, Catherine; Perez, Angel; Stutzman, Brent; Barnhill, Brooke A

2016-01-01

In a synthesis of the research, the authors present findings from communication and literacy studies conducted with children and youth with deafblindness, ages 0-22 years, and published in peer-reviewed journals, 1990-2015. Findings are organized within the structure of the four aspects of communication: form, function, content, context. The studies implemented child-guided and systematic instructional approaches. Studies on form addressed tangible representations, gestures, pictures, and technologies to increase expressive communication rates, and included research focusing on specific functions. Most of the research on context addressed the coaching of adult communication partners to improve responsiveness. Research on communication by children who are deafblind has focused almost exclusively on improving expressive communication. Therefore, there is a need for research on receptive communication and comprehension. In the area of literacy, studies are needed on emergent literacy and reading and writing interventions for children who are deafblind.

Coast, Ernestina; Jones, Eleri; Portela, Anayda; Lattof, Samantha R.

2014-01-01

Background A vast body of global research shows that cultural factors affect the use of skilled maternity care services in diverse contexts. While interventions have sought to address this issue, the literature on these efforts has not been synthesised. This paper presents a systematic mapping of interventions that have been implemented to address cultural factors that affect women's use of skilled maternity care. It identifies and develops a map of the literature; describes the range of interventions, types of literature and study designs; and identifies knowledge gaps. Methods and Findings Searches conducted systematically in ten electronic databases and two websites for literature published between 01/01/1990 and 28/02/2013 were combined with expert-recommended references. Potentially eligible literature included journal articles and grey literature published in English, French or Spanish. Items were screened against inclusion and exclusion criteria, yielding 96 items in the final map. Data extracted from the full text documents are presented in tables and a narrative synthesis. The results show that a diverse range of interventions has been implemented in 35 countries to address cultural factors that affect the use of skilled maternity care. Items are classified as follows: (1) service delivery models; (2) service provider interventions; (3) health education interventions; (4) participatory approaches; and (5) mental health interventions. Conclusions The map provides a rich source of information on interventions attempted in diverse settings that might have relevance elsewhere. A range of literature was identified, from narrative descriptions of interventions to studies using randomised controlled trials to evaluate impact. Only 23 items describe studies that aim to measure intervention impact through the use of experimental or observational-analytic designs. Based on the findings, we identify avenues for further research in order to better document and measure the impact of interventions to address cultural factors that affect use of skilled maternity care.

The rising prevalence of metabolic syndrome among adolescents has not been effectively addressed by current campus-based health promotions. Using the Internet in these promotions may help health professionals achieve better healthcare management. The purpose of the present study was to explore the design requirements of an e-health management platform from the subjective perspective of adolescent girls who were at a high risk of metabolic syndrome. The findings may provide a reference for designing nursing interventions that more effectively promote healthly lifestyle habits to adolescents. This qualitative study employed a snowball approach and used a semi-structured interview guide to collect data. A total of 20 Taiwanese adolescent females who were at a high risk of metabolic syndrome, aged 16-20 years, able to speak Mandarin or Taiwanese, and willing to participate and to have their sessions tape-recorded were enrolled as participants and engaged individually in in-depth interviews. The constant comparative method was used to inductively analyze the interview data. Five main themes related to the e-health management platform emerged from the data. These themes included: an attractive and user-friendly website interface, access to reliable information and resources, provision of tailored health information, access to peer support, and self-monitoring and learning tools. The findings highlight the key design needs of an e-Health management platform from the perspective of adolescent girls who are at a high risk of metabolic syndrome. The identified themes may be addressed in future revisions / developments of these platforms in order to better address the needs of this vulnerable population and to effectively reduce the incidence of metabolic syndrome. The authors hope that the results of the present study may be used to provide better healthcare and support for adolescent girls with metabolic syndrome.

2012-01-01

In this paper, an integrated approach for gear health prognostics using particle filters is presented. The presented method effectively addresses the issues in applying particle filters to gear health prognostics by integrating several new components into a particle filter: (1) data mining based techniques to effectively define the degradation state transition and measurement functions using a one-dimensional health index obtained by whitening transform; (2) an unbiased l-step ahead RUL estimator updated with measurement errors. The feasibility of the presented prognostics method is validated using data from a spiral bevel gear case study.

Accuracy of commercial geocoding: assessment and implications.

Published studies of geocoding accuracy often focus on a single geographic area, address source or vendor, do not adjust accuracy measures for address characteristics, and do not examine effects of inaccuracy on exposure measures. We addressed these issues in a Women's Health Initiative ancillary study, the Environmental Epidemiology of Arrhythmogenesis in WHI. Addresses in 49 U.S. states (n = 3,615) with established coordinates were geocoded by four vendors (A-D). There were important differences among vendors in address match rate (98%; 82%; 81%; 30%), concordance between established and vendor-assigned census tracts (85%; 88%; 87%; 98%) and distance between established and vendor-assigned coordinates (mean rho [meters]: 1809; 748; 704; 228). Mean rho was lowest among street-matched, complete, zip-coded, unedited and urban addresses, and addresses with North American Datum of 1983 or World Geodetic System of 1984 coordinates. In mixed models restricted to vendors with minimally acceptable match rates (A-C) and adjusted for address characteristics, within-address correlation, and among-vendor heteroscedasticity of rho, differences in mean rho were small for street-type matches (280; 268; 275), i.e. likely to bias results relying on them about equally for most applications. In contrast, differences between centroid-type matches were substantial in some vendor contrasts, but not others (5497; 4303; 4210) p(interaction) < 10(-4), i.e. more likely to bias results differently in many applications. The adjusted odds of an address match was higher for vendor A versus C (odds ratio = 66, 95% confidence interval: 47, 93), but not B versus C (OR = 1.1, 95% CI: 0.9, 1.3). That of census tract concordance was no higher for vendor A versus C (OR = 1.0, 95% CI: 0.9, 1.2) or B versus C (OR = 1.1, 95% CI: 0.9, 1.3). Misclassification of a related exposure measure--distance to the nearest highway--increased with mean rho and in the absence of confounding, non-differential misclassification of this distance biased its hypothetical association with coronary heart disease mortality toward the null. Geocoding error depends on measures used to evaluate it, address characteristics and vendor. Vendor selection presents a trade-off between potential for missing data and error in estimating spatially defined attributes. Informed selection is needed to control the trade-off and adjust analyses for its effects.

This study investigated the role of present and future time perspectives, and their relationships with subjective norms and beliefs regarding violence, in predicting violent behaviors among urban middle school students in the Midwestern United States. Although present time perspective covaried with subjective norms and beliefs, each made a unique prediction of self-reported violent behaviors. Future time perspective was not a significant predictor when accounting for these relationships. In addition, present orientation moderated the relationship between subjective norms and beliefs and rates of violent behaviors; those with higher present orientations exhibited stronger associations. We replicated this pattern of results in data from new participants in a subsequent wave of the study. Interventions that explicitly address issues related to time perspective may be effective in reducing early adolescent violence.

Wölfer, Ralf; Scheithauer, Herbert

2014-01-01

Bullying is a social phenomenon and although preventive interventions consequently address social mechanisms, evaluations hardly consider the complexity of peer processes. Therefore, the present study analyzes the efficacy of the fairplayer.manual bullying prevention program from a social network perspective. Within a pretest-posttest control group design, longitudinal data were available from 328 middle-school students (MAge  = 13.7 years; 51% girls), who provided information on bullying behavior and interaction patterns. The revealed network parameters were utilized to examine the network change (MANCOVA) and the network dynamics (SIENA). Across both forms of analyses, findings revealed the hypothesized intervention-based decrease of bullies' social influence. Hence the present bullying prevention program, as one example of programs that successfully addresses both individual skills and social mechanisms, demonstrates the desired effect of reducing contextual opportunities for the exhibition of bullying behavior. © 2014 Wiley Periodicals, Inc.

This chapter introduces the characterizing aspects of embedded systems, and discusses the specific features that a designer should address to an embedded system “rugged”, i.e., able to operate reliably in harsh environments. The chapter addresses both the hardware and the less obvious software aspect. After presenting a current list of certifications for ruggedization, the chapters present a case study that focuses on the interaction of the hardware and software layers in reactive real-time system. In particular, it shows how the use of fast FPGA prototyping could provide insights on unexpected factors that influence the performance and thus responsiveness to eventsmore » of a scheduling algorithm for multiprocessor systems that manages both periodic, hard real-time task, and aperiodic tasks. The main lesson is that to make the system “rugged”, a designer should consider these issues by, for example, overprovisioning resources and/or computation capabilities.« less

This study presents a survey of State Mental Health Authorities' (SMHA) programs and policies addressing the needs of adult clients in their role as parent. Six program and policy areas (parent status identification, parent-focused residential programs, parent functioning assessment, outpatient services for parents, policies for hospitalized parents, and policies for hospitalized pregnant women) are examined. Results of the most recent 1999 survey are compared with results from a similar 1990 survey. This comparison reveals that the majority of SMHAs continue to overlook adult clients in their parenting role, and few SMHA programs and policies address issues of parenting.

With the advent of personalized and evidence-based medicine, the need for a framework to analyze/interpret quantitative measurements (blood work, toxicology, etc.) with qualitative descriptions (specialist reports after reading images, bio-medical knowledge-bases) to predict diagnostic risks is fast emerging. Addressing this need, we pose and address the following questions (i) How can we jointly analyze both qualitative and quantitative data ? (ii) Is the fusion of multi-structure data expected to provide better insights than either of them individually ? We present experiments on two bio-medical data sets - mammography and traumatic brain studies to demonstrate architectures and tools for evidence-pattern search.

2003-01-01

This paper describes active tip clearance control research being conducted by NASA to improve turbine engine systems. The target application for this effort is commercial aircraft engines. However, technologies developed for clearance control can benefit a broad spectrum of current and future turbomachinery. The first portion of the paper addresses the research from a programmatic viewpoint. Recent studies that provide motivation for the work, identification of key technologies, and NASA's plan for addressing deficiencies in the technologies are discussed. The later portion of the paper drills down into one of the key technologies by presenting equations and results for a preliminary dynamic model of the tip clearance phenomena.

Exercise effects on bone mineral density in older men: a systematic review with special emphasis on study interventions.

This systematic review detected only limited positive effects of exercise on bone mineral density in older men. Further, based on the present literature, we were unable to suggest dedicated exercise prescriptions for this male cohort that might differ from recommendations based on studies with postmenopausal women. The primary aim of this systematic review was to determine the effect of exercise on bone mineral density (BMD) in healthy older men. A systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement included only randomized or non-randomized controlled trials of exercise training ≥ 6 months with study groups of ≥ eight healthy men aged 50 years or older, not using bone-relevant pharmacological therapy, that determined BMD by dual-energy X-ray absorptiometry. We searched PubMed, Scopus, Web of Science, Cochrane, Science Direct, and Eric up to November 2016. Risk of bias was assessed using the PEDro scale. We identified eight trials with 789 participants (PEDro-score, mean value 6 of 10) which satisfied our eligibility criteria. Studies vary considerably with respect to type and composition of exercise. Study interventions of six trials were considered to be appropriate for successfully addressing BMD in this cohort. Between-group differences were not or not consistently reported by three studies. Three studies reported significant exercise effects on BMD for proximal femur; one of them determined significant differences between the exercise groups. None of the exercise trials determined significant BMD effects at the lumbar spine. Based on the present studies, there is only limited evidence for a favorable effect of exercise on BMD in men. More well-designed and sophisticated studies on BMD in healthy older men have to address this topic. Further, there is a need to define intervention quality standards and implement a universal scoring system that allows this pivotal determinant to be addressed much more intensively.

The persistence of many saproxylic (wood-living) species depends on a readily available supply of coarse woody debris (CWD). Most studies of CWD inputs address stand-level patterns, despite the fact that many saproxylic species depend on landscape-level supplies of CWD. In the present study we used dated CWD inputs (tree mortality events) at each of 14 Norway spruce (...

Packet flow monitoring tool and method

DOEpatents

Thiede, David R [Richland, WA

2009-07-14

A system and method for converting packet streams into session summaries. Session summaries are a group of packets each having a common source and destination internet protocol (IP) address, and, if present in the packets, common ports. The system first captures packets from a transport layer of a network of computer systems, then decodes the packets captured to determine the destination IP address and the source IP address. The system then identifies packets having common destination IP addresses and source IP addresses, then writes the decoded packets to an allocated memory structure as session summaries in a queue.

Toward Information Infrastructure Studies: Ways of Knowing in a Networked Environment

NASA Astrophysics Data System (ADS)

Bowker, Geoffrey C.; Baker, Karen; Millerand, Florence; Ribes, David

This article presents Information Infrastructure Studies, a research area that takes up some core issues in digital information and organization research. Infrastructure Studies simultaneously addresses the technical, social, and organizational aspects of the development, usage, and maintenance of infrastructures in local communities as well as global arenas. While infrastructure is understood as a broad category referring to a variety of pervasive, enabling network resources such as railroad lines, plumbing and pipes, electrical power plants and wires, this article focuses on information infrastructure, such as computational services and help desks, or federating activities such as scientific data repositories and archives spanning the multiple disciplines needed to address such issues as climate warming and the biodiversity crisis. These are elements associated with the internet and, frequently today, associated with cyberinfrastructure or e-science endeavors. We argue that a theoretical understanding of infrastructure provides the context for needed dialogue between design, use, and sustainability of internet-based infrastructure services. This article outlines a research area and outlines overarching themes of Infrastructure Studies. Part one of the paper presents definitions for infrastructure and cyberinfrastructure, reviewing salient previous work. Part two portrays key ideas from infrastructure studies (knowledge work, social and political values, new forms of sociality, etc.). In closing, the character of the field today is considered.

Addressing trend-related changes within cumulative effects studies in water resources planning

Canter, L.W., E-mail: envimptr@aol.com; Chawla, M.K.; Swor, C.T.

Summarized herein are 28 case studies wherein trend-related causative physical, social, or institutional changes were connected to consequential changes in runoff, water quality, and riparian and aquatic ecological features. The reviewed cases were systematically evaluated relative to their identified environmental effects; usage of analytical frameworks, and appropriate models, methods, and technologies; and the attention given to mitigation and/or management of the resultant causative and consequential changes. These changes also represent important considerations in project design and operation, and in cumulative effects studies associated therewith. The cases were grouped into five categories: institutional changes associated with legislation and policies (seven cases);more » physical changes from land use changes in urbanizing watersheds (eight cases); physical changes from land use changes and development projects in watersheds (four cases); physical, institutional, and social changes from land use and related policy changes in river basins (three cases); and multiple changes within a comprehensive study of land use and policy changes in the Willamette River Basin in Oregon (six cases). A tabulation of 110 models, methods and technologies used in the studies is also presented. General observations from this review were that the features were unique for each case; the consequential changes were logically based on the causative changes; the analytical frameworks provided relevant structures for the studies, and the identified methods and technologies were pertinent for addressing both the causative and consequential changes. One key lesson was that the cases provide useful, “real-world” illustrations of the importance of addressing trend-related changes in cumulative effects studies within water resources planning. Accordingly, they could be used as an “initial tool kit” for addressing trend-related changes.« less

Effectively addressing wicked health problems, that is, those arising from complex multifactorial biological and socio-economic causes, requires transdisciplinary action. However, a significant body of research points toward substantial difficulties in cultivating transdisciplinary collaboration. Accordingly, this article presents the results of a study that adapts Systems Ethnography and Qualitative Modeling (SEQM) in response to wicked health problems. SEQM protocols were designed to catalyze transdisciplinary responses to national defense concerns. We adapted these protocols to address cancer-obesity comorbidity and risk coincidence. In so doing, we conducted participant-observations and interviews with a diverse range of health care providers, community health educators, and health advocacy professionals who target either cancer or obesity. We then convened a transdisciplinary conference designed to catalyze a coordinated response. The findings offer productive insights into effective ways of catalyzing transdisciplinarity in addressing wicked health problems action and demonstrate the promise of SEQM for continued use in health care contexts.

Implementing portfolio in postgraduate general practice training. Benefits and recommendations.

PubMed

Alotaibi, Fawaz S

2012-10-01

This paper presents a review to explore the literature focusing on portfolio in postgraduate general practice (GP) training, and to examine the impact of implementation of portfolio on learning process, as well as proposing recommendations for its implementation in postgraduate GP training. An electronic search was carried out on several databases for studies addressing portfolio in postgraduate GP training. Six articles were included to address specifically the effectiveness of portfolio in postgraduate GP training. Five of them described successful experiences of portfolio-based learning implementation. Only one article addressed portfolio-based assessment in postgraduate GP training. The existing evidence provides various benefits of professional portfolio-based learning. It does appear to have advantages of stimulating reflective learning, promoting proactive learning, and bridging the hospital experiences of the learners to GP. Moreover, the challenges to implementation of portfolio-based learning are often based on orientation and training of stakeholders.

Objective The diagnosis and treatment of gynecologic cancer can cause short- and long-term negative effects on sexual health and quality of life (QoL). The aim of this article is to present a comprehensive overview of the sexual health concerns of gynecologic cancer survivors and discuss evidence-based treatment options for commonly encountered sexual health issues. Methods A comprehensive literature search of English language studies on sexual health in gynecologic cancer survivors and the treatment of sexual dysfunction was conducted in MEDLINE databases. Relevant data are presented in this review. Additionally, personal and institutional practices are incorporated where relevant. Results Sexual dysfunction is prevalent among gynecologic cancer survivors as a result of surgery, radiation, and chemotherapy--negatively impacting QoL. Many patients expect their healthcare providers to address sexual health concerns, but most have never discussed sex-related issues with their physician. Lubricants, moisturizers, and dilators are effective, simple, non-hormonal interventions that can alleviate the morbidity of vaginal atrophy, stenosis, and pain. Pelvic floor physical therapy can be an additional tool to address dyspareunia. Cognitive behavioral therapy has been shown to be beneficial to patients reporting problems with sexual interest, arousal, and orgasm. Conclusion Oncology providers can make a significant impact on the QoL of gynecologic cancer survivors by addressing sexual health concerns. Simple strategies can be implemented into clinical practice to discuss and treat many sexual issues. Referral to specialized sexual health providers may be needed to address more complex problems.

Fox, Donald A.; Grandjean, Philippe; de Groot, Didima; Paule, Merle

2013-01-01

To date, only a small number of commercial chemicals have been tested and documented as developmental neurotoxicants. Moreover, an increasing number of epidemiological, clinical and experimental studies suggest an association between toxicant or drug exposure during the perinatal period and the development of metabolic-related diseases and neurotoxicity later in life. The four speakers in this symposium presented their research results on different neurotoxic chemicals as they relate to the developmental origins of health and adult disease (DOHaD). Philippe Grandjean presented epidemiological data on children exposed to methylmercury and discussed the behavioral outcome measures as they relate to age and stage of brain development. Donald A. Fox presented data that low-to-moderate dose human equivalent gestational lead exposure produced late-onset obesity, and motor and coordination dysfunction only in male mice. Didima de Groot discussed the role of caloric restriction and/or high fat diets during gestation and/or postnatal development in mediating the metabolic and neurotoxic effects of developmental methylmercury exposure in rats. Merle G. Paule addressed the long-term changes in learning, motivation and short-term memory in aged Rhesus monkeys following 24 hour exposure to ketamine during early development. Overall, these presentations addressed fundamental issues in the emerging areas of lifetime neurotoxicity testing, differential vulnerable periods of exposure, nonmonotonic dose-response effects and neurotoxic risk assessment.
