    Opt-in consent is usually required for research, but is known to introduce selection bias. This is a particular problem for large scale epidemiological studies using only pre-collected health data. Most previous studies have shown that members of the public value opt-in consent and can perceive research without consent as an invasion of privacy. Past research has suggested that people are generally unaware of research processes and existing safeguards, and that education may increase the acceptability of research without prior informed consent, but this recommendation has not been formally evaluated. Our objectives were to determine the range of public opinion about the use of existing medical data for research and to explore views about consent to a secondary review of medical records for research. We also investigated the effect of the provision of detailed information about the potential effect of selection bias on public acceptability of the use of data for research. We carried out a systematic review of existing literature on public attitudes to secondary use of existing health records identified by searching PubMed (1966-present), Embase (1974-present) and reference lists of identified studies to provide a general overview, followed by a qualitative focus group study with 19 older men recruited from rural and suburban primary care practices in the UK to explore key issues in detail. The systematic review identified twenty-seven relevant papers and the findings suggested that males and older people were more likely to consent to a review of their medical data. Many studies noted participants' lack of knowledge about research processes and existing safeguards and this was reflected in the focus groups. Focus group participants became more accepting of the use of pre-collected medical data without consent after being given information about selection bias and research processes. All participants were keen to contribute to NHS-related research but some were concerned about data-sharing for commercial gain and the potential misuse of information. Increasing public education about research and specific targeted information provision could promote trust in research processes and safeguards, which in turn could increase the acceptability of research without specific consent where the need for consent would lead to biased findings and impede research necessary to improve public health.

    Importance Sex is a variable that is poorly controlled for in clinical research. Objective Determine if sex bias exists in human surgical clinical research, determine if data are reported and analyzed using sex as an independent variable, and identify specialties where the greatest and least sex biases exist. Design Review and data abstraction from published peer-reviewed manuscripts. Setting All original peer-reviewed manuscripts published in 2011 and 2012 in Annals of Surgery, American Journal of Surgery, JAMA Surgery, Journal of Surgical Research, and Surgery. Main Outcome Measures Study type, location, number and sex of subjects, sex matching, and inclusion of sex-based reporting, statistical analysis, and discussion of data. Results Of 2,347 articles reviewed, 1,668 included human subjects. After excluding 365 articles, 1,303 manuscripts remained: 17 (1%) included only males, 41 (3%) included only females, 1,020 (78%) included males and females, and 225 (17%) did not document the sex of the subjects. While females represent over 50% of the total number of subjects included, considerable variability existed with the number of male, female, and unspecified subjects included among the journals, between US domestic and international studies, and between single versus multi-center studies. For manuscripts included in the study, only 38% reported these data by sex, 33% analyzed these data by sex, and 23% included a discussion of sex-based results. Sex matching of the subjects included in the research was poor, with only 18% of the studies matching the inclusion of both sexes by 80%. Upon analysis of the different surgical specialties, a wide variation in sex-based inclusion, matching, and data reporting existed, with colorectal surgery having the best matching of males and females and cardiac surgery having the worst. Conclusion Our data show that sex bias exists in human surgical clinical research. Few studies included men and women equally, less than one-third performed data analysis by sex, and there was wide variation in inclusion and matching of the sexes among the specialties and the journals reviewed. Because clinical research serves as the foundation for evidence-based medicine, it is imperative that this disparity be addressed so that therapies benefit both sexes. PMID:27551816

    2017-07-03

    Studies investigating the risk factors for or causation of dementia must consider subjects prior to disease onset. To overcome the limitations of prospective studies and self-reported recall of information, the use of existing data is key. This review provides a narrative account of dementia ascertainment methods using sources of existing data. The literature search was performed using: MEDLINE, EMBASE, PsychInfo and Web of Science. Included articles reported a UK-based study of dementia in which cases were ascertained using existing data. Existing data included that which was routinely collected and that which was collected for previous research. After removing duplicates, abstracts were screened and the remaining articles were included for full-text review. A quality tool was used to evaluate the description of the ascertainment methodology. Of the 3545 abstracts screened, 360 articles were selected for full-text review. 47 articles were included for final consideration. Data sources for ascertainment included: death records, national datasets, research databases and hospital records among others. 36 articles used existing data alone for ascertainment, of which 27 used only a single data source. The most frequently used source was a research database. Quality scores ranged from 7/16 to 16/16. Quality scores were better for articles with dementia ascertainment as an outcome. Some papers performed validation studies of dementia ascertainment and most indicated that observed rates of dementia were lower than expected. We identified a lack of consistency in dementia ascertainment methodology using existing data. With no data source identified as a "gold-standard", we suggest the use of multiple sources. Where possible, studies should access records with evidence to confirm the diagnosis. Studies should also calculate the dementia ascertainment rate for the population being studied to enable a comparison with an expected rate.

    Traditional approaches to clinical research have, as yet, failed to provide effective treatments for vascular dementia (VaD). Novel approaches to collation and synthesis of data may allow for time and cost efficient hypothesis generating and testing. These approaches may have particular utility in helping us understand and treat a complex condition such as VaD. We present an overview of new uses for existing data to progress VaD research. The overview is the result of consultation with various stakeholders, focused literature review and learning from the group's experience of successful approaches to data repurposing. In particular, we benefitted from the expert discussion and input of delegates at the 9 th International Congress on Vascular Dementia (Ljubljana, 16-18 th October 2015). We agreed on key areas that could be of relevance to VaD research: systematic review of existing studies; individual patient level analyses of existing trials and cohorts and linking electronic health record data to other datasets. We illustrated each theme with a case-study of an existing project that has utilised this approach. There are many opportunities for the VaD research community to make better use of existing data. The volume of potentially available data is increasing and the opportunities for using these resources to progress the VaD research agenda are exciting. Of course, these approaches come with inherent limitations and biases, as bigger datasets are not necessarily better datasets and maintaining rigour and critical analysis will be key to optimising data use.

  17. Designing and implementing an authentic science research program

    NASA Astrophysics Data System (ADS)

    Rosvally, Harry Edward, Jr.

    Science research programs have become a popular elective course in high schools around the country. As the popularity of these programs grows, school districts need a guide by which to implement science research in their own schools. This study sought to provide this information by answering the following questions: (1) What are the most important features in existing research program models? (2) How do schools that have an existing research program define "success"? (3) How do different factors (i.e., budget, professional development, scheduling, recruitment effort, curriculum, and mentors) affect the scope and implementation of a research program? (4) Which features and factors support inclusiveness as a goal for a research program? (5) What kinds of indicators are appropriate for assessing the progress toward an inclusive science research program? After reviewing the literature, six sites with existing research programs were selected for participation in the study. Interviews with teachers and students were conducted during site visits. Interviews with mentors were conducted by telephone. Although the six models in this study were different from one another, there were common characteristics. Students conducted their own review of the literature. Upon completion of the actual research, students published or otherwise communicated their findings to the larger scientific community through regional and national competitions and non-competitive science symposia. This study was also able to identify significant elements that contribute to successful programs. These included: teacher selection; budget requirements; mentor qualities; recruitment and retention practices; and overall structure. As a result of the findings during the research, this study makes recommendations for the successful implementation of a research program.

    2015-06-01

    This article reports on the "Novel Strategies for Sedentary Behavior Research" session of the Sedentary Behavior: Identifying Research Priorities workshop. The purpose of this session of the workshop were to propose strategies for accomplishing a research agenda in dealing with sedentary behavior and to consider research priorities for people at high risk for excess sedentary behavior. The four major recommendations from this workshop were as follows: 1) To add repeated objective measures of physical activity and sedentary behavior to existing cohort studies and standardize approaches to measurement and analysis. Epidemiologic studies will be the most efficient design for addressing some research questions. 2) To increase research efficiency, consider the advantages of a network of connected research studies and health systems. Advantages include access to existing data in electronic health records. 3) To carefully select a variety of high-risk study populations and preplan collaboration among studies in intervention research. This strategy can efficiently address the breadth of issues in sedentary behavior research. 4) To include comparative effectiveness designs and pure environmental interventions in intervention research. This strategy facilitates and enhances translation of interventions into practice.

  19. Data standards for clinical research data collection forms: current status and challenges.

    PubMed

    Richesson, Rachel L; Nadkarni, Prakash

    2011-05-01

    Case report forms (CRFs) are used for structured-data collection in clinical research studies. Existing CRF-related standards encompass structural features of forms and data items, content standards, and specifications for using terminologies. This paper reviews existing standards and discusses their current limitations. Because clinical research is highly protocol-specific, forms-development processes are more easily standardized than is CRF content. Tools that support retrieval and reuse of existing items will enable standards adoption in clinical research applications. Such tools will depend upon formal relationships between items and terminological standards. Future standards adoption will depend upon standardized approaches for bridging generic structural standards and domain-specific content standards. Clinical research informatics can help define tools requirements in terms of workflow support for research activities, reconcile the perspectives of varied clinical research stakeholders, and coordinate standards efforts toward interoperability across healthcare and research data collection.

    2014-08-01

    Randomized controlled trials (RCTs) support the effectiveness of virtual reality exposure therapy (VRET) for anxiety disorders; however, the overall quality of the VRET RCT literature base has yet to be evaluated. This study reviewed 27 VRET RCTs and the degree of adherence to 8 RCT research design criteria derived from existing standards. Adherence to the study quality criteria was generally low as the articles met an average 2.85 criteria (SD=1.56). None of the studies met more than six quality criteria. Study quality did not predict effect size; however, a reduction in effect size magnitude was observed for studies with larger sample sizes when comparing VRET to non-active control groups. VRET may be an effective method of treatment but caution should be exercised in interpreting the existing body of literature supporting VRET relative to existing standards of care. The need for well-designed VRET research is discussed. Copyright © 2014. Published by Elsevier Ltd.

  4. Exploring the use of storytelling in quantitative research fields using a multiple case study method

    NASA Astrophysics Data System (ADS)

    Matthews, Lori N. Hamlet

    The purpose of this study was to explore the emerging use of storytelling in quantitative research fields. The focus was not on examining storytelling in research, but rather how stories are used in various ways within the social context of quantitative research environments. In-depth interviews were conducted with seven professionals who had experience using storytelling in their work and my personal experience with the subject matter was also used as a source of data according to the notion of researcher-as-instrument. This study is qualitative in nature and is guided by two supporting theoretical frameworks, the sociological perspective and narrative inquiry. A multiple case study methodology was used to gain insight about why participants decided to use stories or storytelling in a quantitative research environment that may not be traditionally open to such methods. This study also attempted to identify how storytelling can strengthen or supplement existing research, as well as what value stories can provide to the practice of research in general. Five thematic findings emerged from the data and were grouped under two headings, "Experiencing Research" and "Story Work." The themes were found to be consistent with four main theoretical functions of storytelling identified in existing scholarly literature: (a) sense-making; (b) meaning-making; (c) culture; and (d) communal function. The five thematic themes that emerged from this study and were consistent with the existing literature include: (a) social context; (b) quantitative versus qualitative; (c) we think and learn in terms of stories; (d) stories tie experiences together; and (e) making sense and meaning. Recommendations are offered in the form of implications for various social contexts and topics for further research are presented as well.

    Objective To summarize findings from a systematic exploration of existing literature and views regarding interdisciplinarity, to discuss themes and components of such work, and to propose a theoretically based definition of interdisciplinary research. Data Sources/Study Setting Two major data sources were used: interviews with researchers from various disciplines, and a systematic review of the education, business, and health care literature from January 1980 through January 2005. Study Design Systematic review of literature, one-on-one interviews, field test (survey). Data Collection/Extraction Methods We reviewed 14 definitions of interdisciplinarity, the characteristics of 42 interdisciplinary research publications from multiple fields of study, and 14 researcher interviews to arrive at a preliminary definition of interdisciplinary research. That definition was then field tested by 12 individuals with interdisciplinary research experience, and their responses incorporated into the definition of interdisciplinary research proposed in this paper. Principal Findings Three key definitional characteristics were identified: the qualitative mode of research (and its theoretical underpinnings), existence of a continuum of synthesis among disciplines, and the desired outcome of the interdisciplinary research. Conclusion Existing literature from several fields did not provide a definition for interdisciplinary research of sufficient specificity to facilitate activities such as identification of the competencies, structure, and resources needed for health care and health policy research. This analysis led to the proposed definition, which is designed to aid decision makers in funding agencies/program committees and researchers to identify and take full advantage the interdisciplinary approach, and to serve as a basis for competency-based formalized training to provide researchers with interdisciplinary skills.

    This pilot study explored the link between predatory lending and health care debt among Hispanics. Research shows that links exist between health care costs, debt, poverty, and race ( Draught & Silva, 2003 ; Zeldin & Rukavina, 2007 ). Prior to this study there was no research on the intersection between medical debt and predatory lending although there was reason to believe this link exists ( Seifert, 2004 ). Our results confirm this link and we propose means to break it.

  8. Measuring cognition in teams: a cross-domain review.

    PubMed

    Wildman, Jessica L; Salas, Eduardo; Scott, Charles P R

    2014-08-01

    The purpose of this article is twofold: to provide a critical cross-domain evaluation of team cognition measurement options and to provide novice researchers with practical guidance when selecting a measurement method. A vast selection of measurement approaches exist for measuring team cognition constructs including team mental models, transactive memory systems, team situation awareness, strategic consensus, and cognitive processes. Empirical studies and theoretical articles were reviewed to identify all of the existing approaches for measuring team cognition. These approaches were evaluated based on theoretical perspective assumed, constructs studied, resources required, level of obtrusiveness, internal consistency reliability, and predictive validity. The evaluations suggest that all existing methods are viable options from the point of view of reliability and validity, and that there are potential opportunities for cross-domain use. For example, methods traditionally used only to measure mental models may be useful for examining transactive memory and situation awareness. The selection of team cognition measures requires researchers to answer several key questions regarding the theoretical nature of team cognition and the practical feasibility of each method. We provide novice researchers with guidance regarding how to begin the search for a team cognition measure and suggest several new ideas regarding future measurement research. We provide (1) a broad overview and evaluation of existing team cognition measurement methods, (2) suggestions for new uses of those methods across research domains, and (3) critical guidance for novice researchers looking to measure team cognition.

    The practice of medical research with minors in Ireland consist of practices pertaining to therapeutic and non-therapeutic medical research. Clinical trials (a category of therapeutic research), is governed by legislation. However, any other therapeutic research (non-clinical trials research) and non-therapeutic research, e.g. observational medical research such as a longitudinal study of children or non-therapeutic research such as blood sample collection for analysis of cause of disease, are unregulated by legislation. This, article will outline and describe some of the medico-legal issues involved in both types of research and will comment on matters such as what national law exists, how the directive on good clinical practice has been implemented, what guidelines, if any, exist.

    Research, clinical care, and education are the three cornerstones of academic health centers in the United States. The research climate has always been riddled with ebbs and flows, depending on funding availability. During a time of reduced funding, the number and scope of research studies have been reduced, and in some instances, a field of study has been eliminated. Recent reductions in the research funding landscape have led institutions to explore new ways to continue supporting research. Mayo Clinic in Rochester, MN has developed a clinical trial unit within the Department of Medicine, which provides shared resources for many researchers and serves as a solution for training and mentoring new investigators and study teams. By building on existing infrastructure and providing supplemental resources to existing research, the Department of Medicine clinical trial unit has evolved into an effective mechanism for conducting research. This article discusses the creation of a central unit to provide research support in clinical trials and presents the advantages, disadvantages, and required building blocks for such a unit.

    Fowler, Dawnovise N; Faulkner, Monica

    2011-12-01

    In this article, meta-analytic techniques are used to examine existing intervention studies (n = 11) to determine their effects on substance abuse among female samples of intimate partner abuse (IPA) survivors. This research serves as a starting point for greater attention in research and practice to the implementation of evidence-based, integrated services to address co-occurring substance abuse and IPA victimization among women as major intersecting public health problems. The results show greater effects in three main areas. First, greater effect sizes exist in studies where larger numbers of women experienced current IPA. Second, studies with a lower mean age also showed greater effect sizes than studies with a higher mean age. Lastly, studies with smaller sample sizes have greater effects. This research helps to facilitate cohesion in the knowledge base on this topic, and the findings of this meta-analysis, in particular, contribute needed information to gaps in the literature on the level of promise of existing interventions to impact substance abuse in this underserved population.

    2009-06-01

    This paper is a report of an integrative review conducted to critically analyse the contemporary use of qualitative case study methodology in nursing research. Increasing complexity in health care and increasing use of case study in nursing research support the need for current examination of this methodology. In 2007, a search for case study research (published 2005-2007) indexed in the CINAHL, MEDLINE, EMBASE, PsychINFO, Sociological Abstracts and SCOPUS databases was conducted. A sample of 42 case study research papers met the inclusion criteria. Whittemore and Knafl's integrative review method guided the analysis. Confusion exists about the name, nature and use of case study. This methodology, including terminology and concepts, is often invisible in qualitative study titles and abstracts. Case study is an exclusive methodology and an adjunct to exploring particular aspects of phenomena under investigation in larger or mixed-methods studies. A high quality of case study exists in nursing research. Judicious selection and diligent application of literature review methods promote the development of nursing science. Case study is becoming entrenched in the nursing research lexicon as a well-accepted methodology for studying phenomena in health and social care, and its growing use warrants continued appraisal to promote nursing knowledge development. Attention to all case study elements, process and publication is important in promoting authenticity, methodological quality and visibility.

    Agricultural water may contact fresh produce during irrigation and/or when crop protection sprays (e.g., cooling to prevent sunburn, frost protection, and agrochemical mixtures) are applied. This document provides a framework for designing research studies that would add to our understanding of preharvest microbial food safety hazards and control measures pertaining to agricultural water. Researchers will be able to use this document to design studies, to anticipate the scope and detail of data required, and to evaluate previously published work. This document should also be useful for evaluating the strength of existing data and thus should aid in identifying future research needs. Use of this document by the research community may lead to greater consistency or comparability than currently exists among research studies, which may ultimately facilitate direct comparison of hazards and efficacy of controls among different commodities, conditions, and practices.

  11. Education for Sustainable Development and retention: unravelling a research agenda

    NASA Astrophysics Data System (ADS)

    Lotz-Sisitka, Heila

    2010-06-01

    This paper considers the question of what education for sustainable development (ESD) research might signify when linked to the concept of "retention", and how this relation (ESD and retention) might be researched. It considers two different perspectives on retention, as revealed through educational research trajectories, drawing on existing research and case studies. Firstly, it discusses an ESD research agenda that documents retention by focusing on the issue of keeping children in schools. This research agenda is typical of the existing discourses surrounding Education for All (EFA). It then discusses a related ESD research agenda that focuses more on the pedagogical and curricular aspects of retention, as this provides for a deeper understanding of how ESD can contribute to improving the quality of teaching and learning within a wider EFA retention agenda.

    2014-01-01

    Aims: Although Russia has one of the highest rates of alcohol consumption and alcohol-attributable burden of disease, little is known about the existing research on prenatal alcohol exposure (PAE) and Fetal Alcohol Spectrum Disorders (FASDs) in this country. The objective of this study was to locate and review published and unpublished studies related to any aspect of PAE and FASD conducted in or using study populations from Russia. Methods: A systematic literature search was conducted in multiple English and Russian electronic bibliographic databases. In addition, a manual search was conducted in several major libraries in Moscow. Results: The search revealed a small pool of existing research studies related to PAE and/or FASD in Russia (126: 22 in English and 104 in Russian). Existing epidemiological data indicate a high prevalence of PAE and FASD, which underlines the strong negative impact that alcohol has on mortality, morbidity and disability in Russia. High levels of alcohol consumption by women of childbearing age, low levels of contraception use, and low levels of knowledge by health and other professionals regarding the harmful effects of PAE put this country at great risk of further alcohol-affected pregnancies. Conclusions: Alcohol preventive measures in Russia warrant immediate attention. More research focused on alcohol prevention and policy is needed in order to reduce alcohol-related harm, especially in the field of FASD. PMID:24158024

    2012-10-01

    Neuroimaging studies in schizophrenia help clarify the neural substrates underlying the pathogenesis of this neuropsychiatric disorder. Contemporary brain imaging in schizophrenia is predominated by magnetic resonance imaging (MRI)-based research approaches. This review focuses on the various imaging studies from India and their relevance to the understanding of brain abnormalities in schizophrenia. The existing studies are predominantly comprised of structural MRI reports involving region-of-interest and voxel-based morphometry approaches, magnetic resonance spectroscopy and single-photon emission computed tomography/positron emission tomography (SPECT/PET) studies. Most of these studies are significant in that they have evaluated antipsychotic-naïve schizophrenia patients--a relatively difficult population to obtain in contemporary research. Findings of these studies offer robust support to the existence of significant brain abnormalities at very early stages of the disorder. In addition, theoretically relevant relationships between these brain abnormalities and developmental aberrations suggest possible neurodevelopmental basis for these brain deficits.

    PubMed

    Hardison, C D; Schnetzer, T

    1999-01-01

    In the area of clinical trial research, academic medical centers (AMCs) need to create additional capacity and improve performance on vital indicators to attract more studies, as they are currently losing their share to stand-alone research sites. Through the utilization of information technology, AMCs will be in a better position to fend off the competitive threats to their clinical research dollars. Most AMCs are in an enviable position to leverage the value of information technology because of the existing people, processes, and technologies that probably already exist throughout the AMC. The challenge, then, is to deploy these resources in a different manner to support clinical trial research.

  5. Implementation research design: integrating participatory action research into randomized controlled trials

    PubMed Central

    Leykum, Luci K; Pugh, Jacqueline A; Lanham, Holly J; Harmon, Joel; McDaniel, Reuben R

    2009-01-01

    Background A gap continues to exist between what is known to be effective and what is actually delivered in the usual course of medical care. The goal of implementation research is to reduce this gap. However, a tension exists between the need to obtain generalizeable knowledge through implementation trials, and the inherent differences between healthcare organizations that make standard interventional approaches less likely to succeed. The purpose of this paper is to explore the integration of participatory action research and randomized controlled trial (RCT) study designs to suggest a new approach for studying interventions in healthcare settings. Discussion We summarize key elements of participatory action research, with particular attention to its collaborative, reflective approach. Elements of participatory action research and RCT study designs are discussed and contrasted, with a complex adaptive systems approach used to frame their integration. Summary The integration of participatory action research and RCT design results in a new approach that reflects not only the complex nature of healthcare organizations, but also the need to obtain generalizeable knowledge regarding the implementation process.

    PubMed

    Montano, Samantha; Savitt, Amanda

    2016-01-01

    To explore how the existing literature has discussed the vulnerability and needs of women in a disaster context. It will consider the literature's suggestions of how to minimize vulnerability and address the needs of women, including who involved in emergency management should be responsible for such efforts. Empirical journal articles and book chapters from disaster literature were collected that focused on "women" or "gender," and their results and recommendations were analyzed. This review found existing empirical research on women during disasters focuses on their vulnerabilities more than their needs. Second, when researchers do suggest solutions, they tend not to be comprehensive or supported by empirical evidence. Finally, it is not clear from existing research who is responsible for addressing these needs and implementing solutions. Future research should study the intersection of gender and disasters in terms of needs and solutions including who is responsible for implementing solutions.

    To develop a new adverse event (AE) classification for the interventional radiology (IR) procedures and evaluate its clinical, research, and educational value compared with the existing Society of Interventional Radiology (SIR) classification via an SIR member survey. A new AE classification was developed by members of the Standards of Practice Committee of the SIR. Subsequently, a survey was created by a group of 18 members from the SIR Standards of Practice Committee and Service Lines. Twelve clinical AE case scenarios were generated that encompassed a broad spectrum of IR procedures and potential AEs. Survey questions were designed to evaluate the following domains: educational and research values, accountability for intraprocedural challenges, consistency of AE reporting, unambiguity, and potential for incorporation into existing quality-assurance framework. For each AE scenario, the survey participants were instructed to answer questions about the proposed and existing SIR classifications. SIR members were invited via online survey links, and 68 members participated among 140 surveyed. Answers on new and existing classifications were evaluated and compared statistically. Overall comparison between the two surveys was performed by generalized linear modeling. The proposed AE classification received superior evaluations in terms of consistency of reporting (P < .05) and potential for incorporation into existing quality-assurance framework (P < .05). Respondents gave a higher overall rating to the educational and research value of the new compared with the existing classification (P < .05). This study proposed an AE classification system that outperformed the existing SIR classification in the studied domains. Copyright © 2017 SIR. Published by Elsevier Inc. All rights reserved.

  10. The emerging marijuana retail environment: Key lessons learned from tobacco and alcohol retail research.

    PubMed

    Berg, Carla J; Henriksen, Lisa; Cavazos-Rehg, Patricia A; Haardoerfer, Regine; Freisthler, Bridget

    2018-06-01

    The emerging retail market for recreational marijuana use warrants research and surveillance as such markets are established in more US states. This research can be informed by the existing literature regarding tobacco and alcohol, which highlights the impact of spatial access to tobacco and alcohol retailers and exposure to tobacco and alcohol marketing on smoking and drinking among youth and young adults. Prior research indicates that tobacco and alcohol retailers, as well as medical marijuana dispensaries, are disproportionately located in neighborhoods characterized by socioeconomic disadvantage and by higher proportions of racial/ethnic minorities and young adults. Moreover, retail marketing or point-of-sale practices may differentially target subpopulations and differ by neighborhood demography and local policy. This literature and the methods employed for studying the tobacco and alcohol market could inform research on the retail environment for marijuana, as current gaps exist. In particular, much of the existing literature involves cross-sectional research designs; longitudinal studies are needed. Moreover, standardized measures are needed for systematic monitoring of industry marketing practices and to conduct research examining neighborhood differences in exposure to retail marketing for marijuana and its contribution to use modality and frequency, alone and in combination with nicotine and alcohol. The use of standardized measures for tobacco and alcohol marketing have been critical to develop an evidence base from cross-sectional and longitudinal studies that document the impact of retail marketing on substance use by adolescents and adults. Similar research is needed to establish an evidence base to inform federal, state, and local regulations of marijuana. Copyright © 2018 Elsevier Ltd. All rights reserved.

    2018-03-01

    Current literature indicates that intimate partner violence is a complex phenomenon that exists worldwide. However, little is known about why some men of Mexican origin abuse women. This descriptive study was conducted to understand the experiences of men of Mexican origin who abuse their intimate partners. A qualitative research design was used to conduct this study in a south Texas border community adjacent to the United States-Mexico border. This study builds on existing research and furthers the knowledge related to the factors contributing to intimate partner violence, including cultural factors. The results also reinforce the negative impacts of intimate partner violence on children and the family structure. Further research is needed to support the development of a culturally appropriate prevention and intervention program for men of Mexican origin who abuse women and their families.

  12. Citation of prior research has increased in introduction and discussion sections with time: A survey of clinical trials in physiotherapy.

    PubMed

    Hoderlein, Xenia; Moseley, Anne M; Elkins, Mark R

    2017-08-01

    Many clinical trials are reported without reference to the existing relevant high-quality research. This study aimed to investigate the extent to which authors of reports of clinical trials of physiotherapy interventions try to use high-quality clinical research to (1) help justify the need for the trial in the introduction and (2) help interpret the trial's results in the discussion. Data were extracted from 221 clinical trials that were randomly selected from the Physiotherapy Evidence Database: 70 published in 2001 (10% sample) and 151 published in 2015 (10% sample). The Physiotherapy Evidence Database score (which rates methodological quality and completeness of reporting) for each trial was also downloaded. Overall 41% of trial reports cited a systematic review or the results of a search for other evidence in the introduction section: 20% for 2001 and 50% for 2015 (relative risk = 2.3, 95% confidence interval = 1.5-3.8). For the discussion section, only 1 of 221 trials integrated the results of the trial into an existing meta-analysis, but citation of a relevant systematic review did increase from 17% in 2001 to 34% in 2015. There was no relationship between citation of existing research and the total Physiotherapy Evidence Database score. Published reports of clinical trials of physiotherapy interventions increasingly cite a systematic review or the results of a search for other evidence in the introduction, but integration with existing research in the discussion section is very rare. To encourage the use of existing research, stronger recommendations to refer to existing systematic reviews (where available) could be incorporated into reporting checklists and journal editorial guidelines.

  13. Ancillary study management systems: a review of needs

    PubMed Central

    2013-01-01

    Background The valuable clinical data, specimens, and assay results collected during a primary clinical trial or observational study can enable researchers to answer additional, pressing questions with relatively small investments in new measurements. However, management of such follow-on, “ancillary” studies is complex. It requires coordinating across institutions, sites, repositories, and approval boards, as well as distributing, integrating, and analyzing diverse data types. General-purpose software systems that simplify the management of ancillary studies have not yet been explored in the research literature. Methods We have identified requirements for ancillary study management primarily as part of our ongoing work with a number of large research consortia. These organizations include the Center for HIV/AIDS Vaccine Immunology (CHAVI), the Immune Tolerance Network (ITN), the HIV Vaccine Trials Network (HVTN), the U.S. Military HIV Research Program (MHRP), and the Network for Pancreatic Organ Donors with Diabetes (nPOD). We also consulted with researchers at a range of other disease research organizations regarding their workflows and data management strategies. Lastly, to enhance breadth, we reviewed process documents for ancillary study management from other organizations. Results By exploring characteristics of ancillary studies, we identify differentiating requirements and scenarios for ancillary study management systems (ASMSs). Distinguishing characteristics of ancillary studies may include the collection of additional measurements (particularly new analyses of existing specimens); the initiation of studies by investigators unaffiliated with the original study; cross-protocol data pooling and analysis; pre-existing participant consent; and pre-existing data context and provenance. For an ASMS to address these characteristics, it would need to address both operational requirements (e.g., allocating existing specimens) and data management requirements (e.g., securely distributing and integrating primary and ancillary data). Conclusions The scenarios and requirements we describe can help guide the development of systems that make conducting ancillary studies easier, less expensive, and less error-prone. Given the relatively consistent characteristics and challenges of ancillary study management, general-purpose ASMSs are likely to be useful to a wide range of organizations. Using the requirements identified in this paper, we are currently developing an open-source, general-purpose ASMS based on LabKey Server (http://www.labkey.org) in collaboration with CHAVI, the ITN and nPOD.

  15. Assessing the uptake of persistent identifiers by research infrastructure users

    PubMed Central

    Maull, Keith E.

    2017-01-01

    Significant progress has been made in the past few years in the development of recommendations, policies, and procedures for creating and promoting citations to data sets, software, and other research infrastructures like computing facilities. Open questions remain, however, about the extent to which referencing practices of authors of scholarly publications are changing in ways desired by these initiatives. This paper uses four focused case studies to evaluate whether research infrastructures are being increasingly identified and referenced in the research literature via persistent citable identifiers. The findings of the case studies show that references to such resources are increasing, but that the patterns of these increases are variable. In addition, the study suggests that citation practices for data sets may change more slowly than citation practices for software and research facilities, due to the inertia of existing practices for referencing the use of data. Similarly, existing practices for acknowledging computing support may slow the adoption of formal citations for computing resources. PMID:28394907

    Tohari, A.

    2018-02-01

    Rainfall-induced landslides pose a substantial risk to people and infrastructure. For this reason, there have been numerous studies to understand the landslide mechanism. Most of them were performed on the numerical analysis and laboratory experiment. This paper presents a review of existing research on field hydrological condition of soil slopes leading to the initiation of rainfall-induced landslide. Existing methods to study field hydrological response of slopes are first reviewed, emphasizing their limitations and suitability of application. The typical hydrological response profiles in the slope are then discussed. Subsequently, some significant findings on hydrological condition leading to rainfall-induced landslides are summarized and discussed. Finally, several research topics are recommended for future study.

  8. Learning from Recruitment Challenges: Barriers to Diagnosis, Treatment, and Research Participation for Latinos with Symptoms of Alzheimer's Disease

    PubMed Central

    Gelman, Caroline Rosenthal

    2014-01-01

    This paper discusses barriers to diagnosis and treatment of Alzheimer's disease (AD) and concomitantly to participation in AD research as elicited from 29 potential Latino participants who ultimately did not enroll in a study evaluating a caregiver intervention. Nearly half of all individuals contacting the researcher about the intervention study failed to meet criteria stipulating an existing AD diagnosis. Barriers to obtaining a diagnosis include lack of knowledge about AD, perceptions of memory loss as normal aging, and structural barriers to accessing care. A quarter of caregivers contacting the researcher felt too overwhelmed to participate. Many of these barriers have been previously identified as challenges to treatment, suggesting this is not just a methodological research problem but inextricably tied to larger issues of AD knowledge and service accessibility. Engaging Latino communities equitably in the assessment of needs and the process of addressing them, thus ensuring the validity and applicability of the research and findings, is important both for increasing this group's participation in relevant studies and for addressing existing health disparities.

  9. Future directions for positive body image research.

    PubMed

    Halliwell, Emma

    2015-06-01

    The emergence of positive body image research during the last 10 years represents an important shift in the body image literature. The existing evidence provides a strong empirical basis for the study of positive body image and research has begun to address issues of age, gender, ethnicity, culture, development, and intervention in relation to positive body image. This article briefly reviews the existing evidence before outlining directions for future research. Specifically, six areas for future positive body image research are outlined: (a) conceptualization, (b) models, (c) developmental factors, (d) social interactions, (e) cognitive processing style, and (f) interventions. Finally, the potential role of positive body image as a protective factor within the broader body image literature is discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    PubMed

    Links, Paul S; Bender, Ash; Eynan, Rahel; O'Grady, John; Shah, Ravi

    2016-03-10

    The Acute Psychological Trauma (APT) Study was a collaboration between an acute care hospital, a specialized multidisciplinary program designed to meet the mental health needs of injured workers, and a large urban public transit system. The overall purpose was to evaluate a Best Practices Intervention (BPI) for employees affected by acute psychological trauma compared to a Treatment as Usual (TAU) group. The specific purpose is to discuss facilitators and barriers that were recognized in implementing and carrying out mental health research in a workplace setting. Over the course of the APT study, a joint implementation committee was responsible for day-to-day study operations and made regular observations on the facilitators and barriers that arose throughout the study. The facilitators to this study included the longstanding relationships among the partners, increased recognition for the need of mental health research in the workplace, and the existence of a community advisory committee. The significant barriers to doing this study of mental health research in the workplace included differences in organizational culture, inconsistent union support, co-interventions, and stigma. Researchers and funding agencies need to be flexible and provide additional resources in order to overcome the barriers that can exist doing workplace mental health research.

  14. From translational research to open technology innovation systems.

    PubMed

    Savory, Clive; Fortune, Joyce

    2015-01-01

    The purpose of this paper is to question whether the emphasis placed within translational research on a linear model of innovation provides the most effective model for managing health technology innovation. Several alternative perspectives are presented that have potential to enhance the existing model of translational research. A case study is presented of innovation of a clinical decision support system. The paper concludes from the case study that an extending the triple helix model of technology transfer, to one based on a quadruple helix, present a basis for improving the performance translational research. A case study approach is used to help understand development of an innovative technology within a teaching hospital. The case is then used to develop and refine a model of the health technology innovation system. The paper concludes from the case study that existing models of translational research could be refined further through the development of a quadruple helix model of heath technology innovation that encompasses greater emphasis on user-led and open innovation perspectives. The paper presents several implications for future research based on the need to enhance the model of health technology innovation used to guide policy and practice. The quadruple helix model of innovation that is proposed can potentially guide alterations to the existing model of translational research in the healthcare sector. Several suggestions are made for how innovation activity can be better supported at both a policy and operational level. This paper presents a synthesis of the innovation literature applied to a theoretically important case of open innovation in the UK National Health Service. It draws in perspectives from other industrial sectors and applies them specifically to the management and organisation of innovation activities around health technology and the services in which they are embedded.

  8. Enhancing the reporting and transparency of rheumatology research: a guide to reporting guidelines

    PubMed Central

    2013-01-01

    Manuscripts and abstracts from biomedical journals frequently do not contain proper information for meeting required standards and serving the multiple needs of their end users. Reporting guidelines and checklists help researchers to meet those standards by providing rules or principles for specific research areas. Rheumatology research includes a broad range of heterogeneous research areas, each with its own requirements, producing several distinct categories of articles. Our objectives with this article are to raise awareness of the existence and importance of reporting guidelines, to present a structured overview of reporting guidelines that rheumatology journals could apply, and to encourage their use by journal authors, editors, and reviewers, including those of Arthritis Research & Therapy. Internationally recognized reporting guidelines exist for a diversity of research areas. We encourage colleagues to consult the 'Enhancing the QUAlity and Transparency Of health Research' (EQUATOR) network when writing scientific papers. EQUATOR is an international initiative that seeks to improve the reliability and value of biomedical research literature by promoting transparent and accurate reporting of studies. We propose specific reporting guidelines for a number of study designs: animal research, randomized trials, reliability and agreement studies, systematic reviews with and without meta-analyses, diagnostic test accuracy studies, and also observational research including cross-sectional, cohort, and case-control studies. We encourage authors, editors, and reviewers to adhere to and enforce the use of the appropriate guidelines when writing, reading, and reviewing scientific papers. PMID:23448311

  18. Using beta coefficients to impute missing correlations in meta-analysis research: Reasons for caution.

    PubMed

    Roth, Philip L; Le, Huy; Oh, In-Sue; Van Iddekinge, Chad H; Bobko, Philip

    2018-06-01

    Meta-analysis has become a well-accepted method for synthesizing empirical research about a given phenomenon. Many meta-analyses focus on synthesizing correlations across primary studies, but some primary studies do not report correlations. Peterson and Brown (2005) suggested that researchers could use standardized regression weights (i.e., beta coefficients) to impute missing correlations. Indeed, their beta estimation procedures (BEPs) have been used in meta-analyses in a wide variety of fields. In this study, the authors evaluated the accuracy of BEPs in meta-analysis. We first examined how use of BEPs might affect results from a published meta-analysis. We then developed a series of Monte Carlo simulations that systematically compared the use of existing correlations (that were not missing) to data sets that incorporated BEPs (that impute missing correlations from corresponding beta coefficients). These simulations estimated ρ̄ (mean population correlation) and SDρ (true standard deviation) across a variety of meta-analytic conditions. Results from both the existing meta-analysis and the Monte Carlo simulations revealed that BEPs were associated with potentially large biases when estimating ρ̄ and even larger biases when estimating SDρ. Using only existing correlations often substantially outperformed use of BEPs and virtually never performed worse than BEPs. Overall, the authors urge a return to the standard practice of using only existing correlations in meta-analysis. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

  19. The ethics of HIV "cure" research: what can we learn from consent forms?

    PubMed

    Henderson, Gail E

    2015-01-01

    The advent of HIV "cure" research has generated enormous attention, but also concern about its potential to engender false hope, leading to overestimation of benefits and underestimation of risks, and about recruiting relatively healthy participants to studies with uncertain or serious risks. Currently, little is known about potential ethical problems in the ways that informed consent for HIV cure research is described to potential participants. As a first step to address this question, early phase, HIV "cure" research consent forms were analyzed to assess how study aims and potential risks and benefits are presented. Thirteen consent forms from a diverse group of clinical studies were selected to represent the major categories of cure research, including 11 interventional (gene transfer, vaccine intensification, treatment interruption, and latency reversing) and two observational. Consent forms were coded using seven categories, abstracting data on study purpose and design, participant selection criteria, presentation of risks and benefits of participation, and potential return of research results. Findings demonstrate variation and deficiencies that merit attention, but that can largely be addressed by turning to existing guidance about early phase research and specific study designs from other research contexts. The most challenging of these is ensuring that clear, specific, and consistent language is used to describe study aims, risks, benefits, and possible return of results. Informed consent for HIV "cure" research represents an opportunity to apply relevant existing guidance, measure the effectiveness of its application, and develop standardized best-practice policies for consent forms and processes.

    2016-01-01

    Purpose of Review To describe methodological challenges, gaps, and opportunities in U.S. transgender health research. Recent Findings Lack of large prospective observational studies and intervention trials, limited data on risks and benefits of gender affirmation (e.g., hormones and surgical interventions), and inconsistent use of definitions across studies hinder evidence-based care for transgender people. Systematic high-quality observational and intervention-testing studies may be carried out using several approaches, including general population-based, health systems-based, clinic-based, venue-based, and hybrid designs. Each of these approaches has its strength and limitations; however, harmonization of research efforts is needed. Ongoing development of evidence-based clinical recommendations will benefit from a series of observational and intervention studies aimed at identification, recruitment, and follow-up of transgender people of different ages, from different racial, ethnic, and socioeconomic backgrounds and with diverse gender identities. Summary Transgender health research faces challenges that include standardization of lexicon, agreed-upon population definitions, study design, sampling, measurement, outcome ascertainment, and sample size. Application of existing and new methods is needed to fill existing gaps, increase the scientific rigor and reach of transgender health research, and inform evidence-based prevention and care for this underserved population.

  4. Translating research and into everyday clinical practice: Lessons learned from a USA national dental practice-based research network

    PubMed Central

    Gordan, Valeria V.

    2012-01-01

    Clinical studies are of paramount importance for testing and translation of the research findings to the community. Despite the existence of clinical studies, a significant delay exists between the generation of new knowledge and its application into the medical/dental community and their patients. One example is the repair of defective dental restorations. About 75% of practitioners in general dental practices do not consider the repair of dental restorations as a viable alternative to the replacement of defective restorations. Engaging and partnering with health practitioners in the field on studies addressing everyday clinical research questions may offer a solution to speed up the translation of the research findings. Practice-based research (PBR) offers a unique opportunity for practitioners to be involved in the research process, formulating clinical research questions. Additionally, PBR generates evidence-based knowledge with a broader spectrum that can be more readily generalized to the public. With PBR, clinicians are involved in the entire research process from its inception to its dissemination. Early practitioner interaction in the research process may result in ideas being more readily incorporated into practice. This paper discusses PBR as a mean to speed up the translation of research findings to clinical practice. It also reviews repair versus replacement of defective restorations as one example of the delay in the application of research findings to clinical practice. PMID:22889478

    Both the Gravity Recovery and Climate Experiment (GRACE) and Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellites are returning rich data for the study of the solid earth, the oceans, and the climate. Current software analysis tools do not provide researchers with the ease and flexibility required to make full use of this data. We evaluate the capabilities and shortcomings of existing software tools including Mathematica, the GOCE User Toolbox, the ICGEM's (International Center for Global Earth Models) web server, and Tesseroids. Using existing tools as necessary, we design and implement software with the capability to produce gridded data and publication quality renderings from raw gravity data. The straight forward software interface marks an improvement over previously existing tools and makes new space gravity data more useful to researchers. Using the software we calculate Bouguer anomalies of the gravity tensor's vertical component in the Gulf of Mexico, Antarctica, and the 2010 Maule earthquake region. These maps identify promising areas of future research.

    Publicly funded biomedical and health research is expected to achieve the best return possible for taxpayers and for society generally. It is therefore important to know whether such research is more productive if concentrated into a small number of 'research groups' or dispersed across many. We undertook a systematic rapid evidence assessment focused on the research question: do economies of scale and scope exist in biomedical and health research? In other words, is that research more productive per unit of cost if more of it, or a wider variety of it, is done in one location? We reviewed English language literature without date restriction to the end of 2014. To help us to classify and understand that literature, we first undertook a review of econometric literature discussing models for analysing economies of scale and/or scope in research generally (not limited to biomedical and health research). We found a large and disparate literature. We reviewed 60 empirical studies of (dis-)economies of scale and/or scope in biomedical and health research, or in categories of research including or overlapping with biomedical and health research. This literature is varied in methods and findings. At the level of universities or research institutes, studies more often point to positive economies of scale than to diseconomies of scale or constant returns to scale in biomedical and health research. However, all three findings exist in the literature, along with inverse U-shaped relationships. At the level of individual research units, laboratories or projects, the numbers of studies are smaller and evidence is mixed. Concerning economies of scope, the literature more often suggests positive economies of scope than diseconomies, but the picture is again mixed. The effect of varying the scope of activities by a research group was less often reported than the effect of scale and the results were more mixed. The absence of predominant findings for or against the existence of economies of scale or scope implies a continuing need for case by case decisions when distributing research funding, rather than a general policy either to concentrate funding in a few centres or to disperse it across many.

    PubMed

    Nahar, Jesmin; Imam, Tasadduq; Tickle, Kevin S; Garcia-Alonso, Debora

    2013-01-01

    This chapter is a review of data mining techniques used in medical research. It will cover the existing applications of these techniques in the identification of diseases, and also present the authors' research experiences in medical disease diagnosis and analysis. A computational diagnosis approach can have a significant impact on accurate diagnosis and result in time and cost effective solutions. The chapter will begin with an overview of computational intelligence concepts, followed by details on different classification algorithms. Use of association learning, a well recognised data mining procedure, will also be discussed. Many of the datasets considered in existing medical data mining research are imbalanced, and the chapter focuses on this issue as well. Lastly, the chapter outlines the need of data governance in this research domain.

    2007-02-01

    To summarize findings from a systematic exploration of existing literature and views regarding interdisciplinarity, to discuss themes and components of such work, and to propose a theoretically based definition of interdisciplinary research. Two major data sources were used: interviews with researchers from various disciplines, and a systematic review of the education, business, and health care literature from January 1980 through January 2005. Systematic review of literature, one-on-one interviews, field test (survey). We reviewed 14 definitions of interdisciplinarity, the characteristics of 42 interdisciplinary research publications from multiple fields of study, and 14 researcher interviews to arrive at a preliminary definition of interdisciplinary research. That definition was then field tested by 12 individuals with interdisciplinary research experience, and their responses incorporated into the definition of interdisciplinary research proposed in this paper. Three key definitional characteristics were identified: the qualitative mode of research (and its theoretical underpinnings), existence of a continuum of synthesis among disciplines, and the desired outcome of the interdisciplinary research. Existing literature from several fields did not provide a definition for interdisciplinary research of sufficient specificity to facilitate activities such as identification of the competencies, structure, and resources needed for health care and health policy research. This analysis led to the proposed definition, which is designed to aid decision makers in funding agencies/program committees and researchers to identify and take full advantage the interdisciplinary approach, and to serve as a basis for competency-based formalized training to provide researchers with interdisciplinary skills.

    Strohacker, Kelley; Galarraga, Omar; Williams, David M.

    2015-01-01

    Background The effectiveness of reinforcing exercise behavior with material incentives is unclear. Purpose Conduct a systematic review of existing research on material incentives for exercise, organized by incentive strategy. Methods Ten studies conducted between January 1965 and June 2013 assessed the impact of incentivizing exercise compared to a non-incentivized control. Results There was significant heterogeneity between studies regarding reinforcement procedures and outcomes. Incentives tended to improve behavior during the intervention while findings were mixed regarding sustained behavior after incentives were removed. Conclusions The most effective incentive procedure is unclear given the limitations of existing research. The effectiveness of various incentive procedures in promoting initial behavior change and habit formation, as well as the use of sustainable incentive procedures should be explored in future research.

    2015-10-01

    Robustness of an existing meta-analysis can justify decisions on whether to conduct an additional study addressing the same research question. We illustrate the graphical assessment of the potential impact of an additional study on an existing meta-analysis using published data on statin use and the risk of acute kidney injury. A previously proposed graphical augmentation approach is used to assess the sensitivity of the current test and heterogeneity statistics extracted from existing meta-analysis data. In addition, we extended the graphical augmentation approach to assess potential changes in the pooled effect estimate after updating a current meta-analysis and applied the three graphical contour definitions to data from meta-analyses on statin use and acute kidney injury risk. In the considered example data, the pooled effect estimates and heterogeneity indices demonstrated to be considerably robust to the addition of a future study. Supportingly, for some previously inconclusive meta-analyses, a study update might yield statistically significant kidney injury risk increase associated with higher statin exposure. The illustrated contour approach should become a standard tool for the assessment of the robustness of meta-analyses. It can guide decisions on whether to conduct additional studies addressing a relevant research question. Copyright © 2015 Elsevier Inc. All rights reserved.

  7. Getting the 'blues': the existence, diffusion and influence of pornography on young peoples' sexual health in Sierra Leone.

    PubMed

    Day, Andrea

    2014-01-01

    While substantial research has examined the effects of pornography on young people in developed societies, existing studies fall short in addressing how sexually-explicit material affects young people in developing countries. The importance of such knowledge increases as the globalising effects of technology expand young peoples' access and exposure to pornography. During the summer of 2012, a study was undertaken in Sierra Leone examining factors affecting young peoples' sexual and reproductive health. The research assessed the influence of HIV knowledge, communication about sex, civil war and contraception myths on sexual behaviours, while remaining open to unanticipated factors. During data collection, respondents identified pornography, also called blues, as an influential factor, detailing its newfound accessibility driven by improved access to information and communication technologies in the country. Respondents also addressed several presumed ways in which pornography impacts young peoples' decisions about sexual health. The following study examines perceived effects of young peoples' exposure to pornography based on existing literature. It then outlines the findings of research conducted in Sierra Leone, drawing on primary data from the respondents and relevant published literature and concludes with proposals for addressing its negative effects.

    2009-12-01

    Geocognition and geoscience education research have experienced a dramatic increase in research productivity and graduate student training in the past decade. At this writing, over twelve U.S. graduate programs dedicated to geocognition and geoscience education research exist within geoscience departments, with numerous other programs housed within education. International research programs are experiencing similar increases in these research domains. This insurgence of graduate training opportunities is due in large part to several factors, including: An increased awareness of the importance of Earth Systems Science to public understanding of science, particularly in light of global concern about climate change; new funding opportunities for science education, cognitive science, and geoscience education research; and, engagement of a significant part of the geosciences and education communities in writing new standards for Earth Systems literacy. Existing research programs blend geoscience content knowledge with research expertise in education, cognitive science, psychology, sociology and related disciplines. Research projects reflect the diversity of interests in geoscience teaching and learning, from investigations of pedagogical impact and professional development to studies of fundamental geocognitive processes.

    2015-10-01

    Few studies have empirically investigated the specific factors in mentoring relationships between undergraduate researchers (mentees) and their mentors in the biological and life sciences that account for mentees' positive academic and career outcomes. Using archival evaluation data from more than 400 mentees gathered over a multi-year period (2005-2011) from several undergraduate biology research programs at a large, Midwestern research university, we validated existing evaluation measures of the mentored research experience and the mentor-mentee relationship. We used a subset of data from mentees (77% underrepresented racial/ethnic minorities) to test a hypothesized social cognitive career theory model of associations between mentees' academic outcomes and perceptions of their research mentoring relationships. Results from path analysis indicate that perceived mentor effectiveness indirectly predicted post-baccalaureate outcomes via research self-efficacy beliefs. Findings are discussed with implications for developing new and refining existing tools to measure this impact, programmatic interventions to increase the success of culturally diverse research mentees and future directions for research.

    2009-06-01

    Building on the disablement process model and the concept of person-environment fit (p-e fit), this review article examines 2 critical questions concerning the role of home environments: (a) What is the recent evidence supporting a relationship between home environments and disability-related outcomes? and (b) What is the recent evidence regarding the effects of home modifications on disability-related outcomes? Using computerized and manual search, we identified relevant peer-reviewed original publications and review articles published between January 1, 1997, and August 31, 2006. For Research Question 1, 25 original investigations and for Research Question 2, 29 original investigations and 10 review articles were identified. For Research Question 1, evidence for a relationship between home environments and disability-related outcomes for older adults exists but is limited by cross-sectional designs and poor research quality. For Research Question 2, evidence based on randomized controlled trials shows that improving home environments enhances functional ability outcomes but not so much falls-related outcomes. Some evidence also exists that studies using a p-e fit perspective result in more supportive findings than studies that do not use this framework. Considerable evidence exists that supports the role of home environments in the disablement process, but there are also inconsistencies in findings across studies. Future research should optimize psychometric properties of home environment assessment tools and explore the role of both objective characteristics and perceived attributions of home environments to understand person-environment dynamics and their impact on disability-related outcomes in old age.

    2018-05-15

    Recent research on family income indicates that a lack of economic stability can affect healthy housing. Those with limited resources experience higher rates of inadequate and unstable housing many times forcing them to live in undesirable communities in which there can be several community-level health-related issues. One community-level health-related factor of concern has been the reemergence of Zika virus. Some research has indicated that a higher risk of catching Zika virus may exist in neighborhoods and areas with unhealthy housing. Therefore, this study sought to explore the existence of a relationship between rental housing and the Zika virus. Our findings indicated a significant correlation existed between renter occupied household units and the presence of Zika virus. This finding is notable as it indicates that renters have a higher chance of contracting Zika virus than non-renters. Future research should further examine the demographic and housing situation in other communities reporting cases of the Zika virus.

    This research study demonstrates a numerical model intended for comprehension the spread of the year 2015 Zika virus disease utilizing the standard SIR framework. In modeling virulent disease dynamics, it is important to explore whether the illness spread could accomplish a pandemic level or it could be eradicated. Information from the year 2015 Zika virus disease event is utilized and Brazil where the event began is considered in this research study. A three dimensional nonlinear differential equation is formulated and solved numerically utilizing the Euler's method in MS excel. It is appeared from the research study that, with health intercessions of public, the viable regenerative number can be decreased making it feasible for the event to cease to exist. It is additionally indicated numerically that the pandemic can just cease to exist when there are no new infected people in the populace.

  14. Aging in Romania: research and public policy.

    PubMed

    Bodogai, Simona I; Cutler, Stephen J

    2014-04-01

    Romania has entered a period of rapid and dramatic population aging. Older Romanians are expected to make up more than 30% of the total population by 2050. Yet, gerontological research is sparse and the few studies of older Romanians that exist are not well used by policy makers. Much of the research is descriptive and focused on needs assessments. Most databases created from studies of older adults are not available for secondary analysis, nor is Romania among the countries included in the Survey of Health and Retirement in Europe. The pension and health insurance systems and the system of social welfare services address the specific needs of older Romanians, but comparing the social protection systems in the European Union with those in Romania suggests the existence of a development lag. The relevant legislation exists but there are still issues regarding the implementation of specially developed social services for older persons. As a result, there are major inadequacies in the organization of the social service system: too few public services, insufficient budget funds, insufficient collaboration between public and private services, and frequently overlapping services.

  15. Reporting Qualitative Research: Standards, Challenges, and Implications for Health Design.

    PubMed

    Peditto, Kathryn

    2018-04-01

    This Methods column describes the existing reporting standards for qualitative research, their application to health design research, and the challenges to implementation. Intended for both researchers and practitioners, this article provides multiple perspectives on both reporting and evaluating high-quality qualitative research. Two popular reporting standards exist for reporting qualitative research-the Consolidated Criteria for Reporting Qualitative Research (COREQ) and the Standards for Reporting Qualitative Research (SRQR). Though compiled using similar procedures, they differ in their criteria and the methods to which they apply. Creating and applying reporting criteria is inherently difficult due to the undefined and fluctuating nature of qualitative research when compared to quantitative studies. Qualitative research is expansive and occasionally controversial, spanning many different methods of inquiry and epistemological approaches. A "one-size-fits-all" standard for reporting qualitative research can be restrictive, but COREQ and SRQR both serve as valuable tools for developing responsible qualitative research proposals, effectively communicating research decisions, and evaluating submissions. Ultimately, tailoring a set of standards specific to health design research and its frequently used methods would ensure quality research and aid reviewers in their evaluations.

    2015-06-26

    The current Ebola Virus Disease (EVD) outbreak in West Africa is the largest in history. As of February 18(th) 2015, 23,258 cases of EVD have been cumulatively reported from Nigeria, Senegal, Guinea, Liberia, Mali, Sierra Leone, Spain, the United Kingdom and the United States of America resulting in more than 9,000 deaths. It is therefore exigent to develop prevention and treatment therapies for EVD. Several new EVD treatments are in clinical development at this time. Based on lessons learned, four critical processes need to be implemented before clinical trials begin. First, all global EVD research need to be coordinated to promote data sharing and synergistic overlap, while reducing unnecessary duplication of efforts. The World Health Organization is well-placed to undertake such an endeavor. Second, governments of affected nations where trials are being proposed need to lead discussions regarding immediate access to any proven medications for epidemics. Also, governments need to leverage international resources to support and expand existing national expertise to jointly conduct high-caliber clinical research; and resources must be used to enhance local technical skills and expand existing personnel. Third, ethics committees must review protocols, monitor the research process, and work closely with research scientists to insure the ethical integrity of research throughout the trials. Fourth, community advisory boards (CAB) need to be formed, linked with existing community leadership structures and organized in conjunction with trial implementation. These community structures should work together with ethics committees to facilitate the study design, informed consent process, and study implementation. We must facilitate communication and mutual understanding between trial communities and research teams, and promote positive collaborations between all stakeholders engaged in EVD research. The community engagement process for EVD research is crucial to address myths and misconceptions, and to promote study volunteers' understanding of the research details. The collaboration between all stakeholders is crucial for continued long term partnership to address EVD outbreak and none of the stakeholders should be left behind in ongoing efforts to develop EVD therapies.

  17. Use of existing systematic reviews for evidence assessments in infectious disease prevention: a comparative case study.

    Given limited resources and time constraints, the use of existing systematic reviews (SR) for the development of evidence-based public health recommendations has become increasingly important. Recently, a five-step approach for identifying, analyzing, appraising and using existing SRs based on recent guidance by the US Agency for Healthcare Research and Quality (AHRQ) was proposed within the Project on a Framework for Rating Evidence in Public Health (PRECEPT). However, case studies are needed to test whether this approach is useful, what challenges arise and how problems can be solved. In two case studies, the five-step approach was applied to integrate existing SRs in the development of evidence-based public health recommendations. Case study A focused on the role of neonatal sepsis as a risk factor for adverse neurodevelopmental outcome. Case study B examined the efficacy, effectiveness and safety of influenza vaccination during pregnancy. For each step, we report the approach of the review team, discuss challenges and describe solutions. For case study A, one existing SR was identified, while in case study B four SRs were eligible for analysis. We found that comparison of inclusion criteria alone was sufficient to judge on relevance of SRs in case study A, but not B. Although methodological quality of all identified SRs was acceptable, risk of bias assessments of individual studies included in the SRs had to be repeated in both case studies. Particular challenges appeared in case study B where multiple SRs addressed the same research question. With the help of spreadsheets comparing the characteristics of the existing SR we decided to use the most comprehensive one for our evidence synthesis and supplemented the results with those from the other SRs. In both case studies using the complete SR was not possible. The five-step approach provided useful and structured guidance and should be routinely applied when using existing SRs as a basis for evidence-based recommendations in public health. In situations where more than one SR has to be considered, the development of spreadsheets comparing characteristics, inclusion criteria, risk of bias, included studies and outcomes seems useful.

    Capacity development for clinical research is held back by a lack of recognition for the skills acquired through involvement in clinical trials and in other varied types of global health research studies. Although some competency frameworks and associated recognised career pathways exist for different clinical research roles, they mostly apply to a single role or study setting. Our experience supports the need for an integrated approach, looking at the many roles in parallel and at all types of clinical research beyond trials. Here, we propose a single, flexible framework which is applicable to the full global health research team, and can be used for recognising staff by highlighting acquired skills and possible progression between various roles. It can also illuminate where capacity needs strengthening and contribute to raising research engagement. Through systematic analysis of existing competency frameworks and current job descriptions covering 11 distinct, broad clinical research roles, we identified and defined 50 key competencies required by the team as a whole and throughout the study life cycle. The competencies are relevant and adaptable to studies that differ in design, geographical location or disease, and fall in five main areas-(1) Ethics, Quality and Risk Management; (2) Study and Site Management; (3) Research Operations; (4) Scientific Thinking; and (5) Professional Skills. A pilot framework and implementation tools are now available online and in paper format. They have the potential to be a new mechanism for enabling research skills development and career progression for all staff engaged in clinical research globally.

    Capacity development for clinical research is held back by a lack of recognition for the skills acquired through involvement in clinical trials and in other varied types of global health research studies. Although some competency frameworks and associated recognised career pathways exist for different clinical research roles, they mostly apply to a single role or study setting. Our experience supports the need for an integrated approach, looking at the many roles in parallel and at all types of clinical research beyond trials.

    A range of organizations are engaged in the production of evidence on the effects of health, social, and economic development programs on human welfare outcomes. However, evidence is often scattered around different databases, web sites, and the gray literature and is often presented in inaccessible formats. Lack of overview of the evidence in a specific field can be a barrier to the use of existing research and prevent efficient use of limited resources for new research. Evidence & Gap Maps (EGMs) aim to address these issues and complement existing synthesis and mapping approaches. EGMs are a new addition to the tools available to support evidence-informed policymaking. To provide an accessible resource for researchers, commissioners, and decision makers, EGMs provide thematic collections of evidence structured around a framework which schematically represents the types of interventions and outcomes of relevance to a particular sector. By mapping the existing evidence using this framework, EGMs provide a visual overview of what we know and do not know about the effects of different programs. They make existing evidence available, and by providing links to user-friendly summaries of relevant studies, EGMs can facilitate the use of existing evidence for decision making. They identify key "gaps" where little or no evidence from impact evaluations and systematic reviews is available and can be a valuable resource to inform a strategic approach to building the evidence base in a particular sector. The article will introduce readers to the concept and methods of EGMs and present a demonstration of the EGM tool using existing examples. Copyright © 2016 Elsevier Inc. All rights reserved.

    2012-01-01

    The Presidential Commission for the Study of Bioethical Issues suggested in its report "Research Across Borders: Proceedings of the International Research Panel of the Presidential Commission for the Study of Bioethical Issues" that the United States should implement a system to compensate research subjects for research-related injuries. This article not only analyzes the Commission's recommendation critically, but also discusses if an ethical obligation exists to compensate study subjects for research-related injuries. In addition, the article compares the status quo of the United States to the one in Germany. Germany is one of the countries, which has an established insurance system for research-related injuries based on a non-fault system.

    Ricks, Wendell R.

    1991-01-01

    A study was conducted to determine the feasibility of using knowledge-based systems architectures for inflight research of primary flight display information management issues. The feasibility relied on the ability to integrate knowledge-based systems with existing onboard aircraft systems. And, given the hardware and software platforms available, the feasibility also depended on the ability to use interpreted LISP software with the real time operation of the primary flight display. In addition to evaluating these feasibility issues, the study determined whether the software engineering advantages of knowledge-based systems found for this application in the earlier workstation study extended to the inflight research environment. To study these issues, two integrated knowledge-based systems were designed to control the primary flight display according to pre-existing specifications of an ongoing primary flight display information management research effort. These two systems were implemented to assess the feasibility and software engineering issues listed. Flight test results were successful in showing the feasibility of using knowledge-based systems inflight with actual aircraft data.

    2014-07-24

    Asthma is a frequent chronic inflammatory disease of the airways, and the assessment of health-related quality of life (HrQoL) is important in both research and routine care. Various asthma-specific measures of HrQoL exist but there is uncertainty which measures are best suited for use in research and routine care. Therefore, the aim of the proposed research is a comprehensive systematic assessment of the measurement properties of the existing measures that were developed to measure asthma-specific quality of life. This study is a systematic review of the measurement properties of asthma-specific measures of health-related quality of life. PubMed and Embase will be searched using a selection of relevant search terms. Eligible studies will be primary empirical studies evaluating, describing or comparing measurement properties of asthma-specific HRQL tools. Eligibility assessment and data abstraction will be performed independently by two reviewers. Evidence tables will be generated for study characteristics, instrument characteristics, measurement properties and interpretability. The quality of the measurement properties will be assessed using predefined criteria. Methodological quality of studies will be assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. A best evidence synthesis will be undertaken if more than one study have investigated a particular measurement property. The proposed systematic review will produce a comprehensive assessment of measurement properties of existing measures of asthma-specific health-related quality of life. We also aim to derive recommendations in order to help researchers and practitioners alike in the choice of instrument. PROSPERO registration number: CRD42014010491.

    2016-08-01

    Despite the quantity of research on child and adolescent mental health being done in schools, little output has focused on the practical aspects of recruiting schools and students into a study. Furthermore, there is limited knowledge on how to develop and sustain productive and mutually beneficial partnerships with schools after the project finishes. A large study examining prevalence of mental health problems in young people involving nine schools is used as an example for the procedure of recruitment and carrying out a research project, while developing and sustaining partnerships with schools. While recruiting the schools, a three-stage model was developed that corresponded closely to the school's needs and existing demands. The suggested procedure for the study, thus, closely reflected the varying existing cultures of participating schools. Partnerships, developed as a result of the project, were used in developing further projects and interventions for promoting good mental health in schools. Rather than a blanket research recruitment and procedural approach with an end to school involvement at the end of the project, the paper advocates for a deeper understanding of the schools' internal culture for improved recruitment and study outcomes. Developed partnerships, when sustained past the completion of research, prove to be a useful tool in applying the findings in promoting good mental health in schools and continuing research further.

  10. Taxonomy of Challenges for Digital Forensics.

    PubMed

    Karie, Nickson M; Venter, Hein S

    2015-07-01

    Since its inception, over a decade ago, the field of digital forensics has faced numerous challenges. Despite different researchers and digital forensic practitioners having studied and analysed various known digital forensic challenges, as of 2013, there still exists a need for a formal classification of these challenges. This article therefore reviews existing research literature and highlights the various challenges that digital forensics has faced for the last 10 years. In conducting this research study, however, it was difficult for the authors to review all the existing research literature in the digital forensic domain; hence, sampling and randomization techniques were employed to facilitate the review of the gathered literature. Taxonomy of the various challenges is subsequently proposed in this paper based on our review of the literature. The taxonomy classifies the large number of digital forensic challenges into four well-defined and easily understood categories. The proposed taxonomy can be useful, for example, in future developments of automated digital forensic tools by explicitly describing processes and procedures that focus on addressing specific challenges identified in this paper. However, it should also be noted that the purpose of this paper was not to propose any solutions to the individual challenges that digital forensics face, but to serve as a survey of the state of the art of the research area. © 2015 American Academy of Forensic Sciences.

  13. The Ethics of HIV “Cure” Research: What Can We Learn from Consent Forms?

    PubMed Central

    2015-01-01

    Abstract The advent of HIV “cure” research has generated enormous attention, but also concern about its potential to engender false hope, leading to overestimation of benefits and underestimation of risks, and about recruiting relatively healthy participants to studies with uncertain or serious risks. Currently, little is known about potential ethical problems in the ways that informed consent for HIV cure research is described to potential participants. As a first step to address this question, early phase, HIV “cure” research consent forms were analyzed to assess how study aims and potential risks and benefits are presented. Thirteen consent forms from a diverse group of clinical studies were selected to represent the major categories of cure research, including 11 interventional (gene transfer, vaccine intensification, treatment interruption, and latency reversing) and two observational. Consent forms were coded using seven categories, abstracting data on study purpose and design, participant selection criteria, presentation of risks and benefits of participation, and potential return of research results. Findings demonstrate variation and deficiencies that merit attention, but that can largely be addressed by turning to existing guidance about early phase research and specific study designs from other research contexts. The most challenging of these is ensuring that clear, specific, and consistent language is used to describe study aims, risks, benefits, and possible return of results. Informed consent for HIV “cure” research represents an opportunity to apply relevant existing guidance, measure the effectiveness of its application, and develop standardized best-practice policies for consent forms and processes.

    2010-01-01

    Human factors (HF) studies are increasingly important as technology infuses into clinical settings. No nursing research reviews exist in this area. The authors conducted a systematic review on designs of clinical technology, 34 articles with 50 studies met inclusion criteria. Findings were classified into three categories based on HF research goals. The majority of studies evaluated effectiveness of clinical design; efficiency was fewest. Current research ranges across many interface types examined with no apparent pattern or obvious rationale. Future research should expand types, settings, participants; integrate displays; and expand outcome variables. PMID:19707093

    2016-01-01

    In late 2015, The National Cancer Institute (NCI) Division of Cancer Prevention convened cancer prevention research experts and stakeholders to discuss the current state of cancer prevention research, identify key prevention research priorities for the NCI, and identify studies that could be conducted within the NCI Community Oncology Research Program (NCORP). Goals included identifying cancer prevention research opportunities offering the highest return on investment, exploring the concept of precision prevention and what is needed to advance this area of research, and identifying possible targets for prevention. Four study populations were considered for cancer prevention research: healthy people; those at increased risk for a specific cancer; people with preneoplastic lesions; and children, adolescents, and young adults. Priorities that emerged include screening (e.g., surveillance intervals, tomosynthesis vs. digital mammography), a pre-cancer genome atlas (PreTCGA), HPV vaccines, immunoprevention of non-infectious origins, and overdiagnosis. Challenges exist, as the priority list is ambitious and potentially expensive. Clinical trials need to be carefully designed to include and maximize prospective tissue collection. Exploring existing co-funding mechanisms will likely be necessary. Finally, relationships with a new generation of physician specialists will need to be cultivated in order to reach the target populations. PMID:27965286

    Corpman, David W

    2013-01-01

    There are nearly 1 billion mobile phone subscribers in China. Health care providers, telecommunications companies, technology firms, and Chinese governmental organizations use existing mobile technology and social networks to improve patient-provider communication, promote health education and awareness, add efficiency to administrative practices, and enhance public health campaigns. This review of mobile health in China summarizes existing clinical research and public health text messaging campaigns while highlighting potential future areas of research and program implementation. Databases and search engines served as the primary means of gathering relevant resources. Included material largely consists of scientific articles and official reports that met predefined inclusion criteria. This review includes 10 reports of controlled studies that assessed the use of mobile technology in health care settings and 17 official reports of public health awareness campaigns that used text messaging. All source material was published between 2006 and 2011. The controlled studies suggested that mobile technology interventions significantly improved an array of health care outcomes. However, additional efforts are needed to refine mobile health research and better understand the applicability of mobile technology in China's health care settings. A vast potential exists for the expansion of mobile health in China, especially as costs decrease and increasingly sophisticated technology becomes more widespread.

  18. Research and knowledge in Ontario tobacco control networks.

    PubMed

    Bickford, Julia J; Kothari, Anita R

    2008-01-01

    This study sought to better understand the role of research knowledge in Ontario tobacco control networks by asking: 1) How is research managed; 2) How is research evaluated; and 3) How is research utilized? This is a secondary analysis of a qualitative study based on individual semistructured interviews with 29 participants between January and May 2006. These participants were purposefully sampled from across four Ministries in the provincial government (n = 7), non-government (n = 15), and public health organizations (n = 7). Interviews were transcribed verbatim and coded and analyzed using QSR N7 qualitative software. This study received ethics approval from The University of Western Ontario Health Research Ethics Board. There exists a dissonance between the preference for peer-reviewed, unbiased, non-partisan knowledge to support claims and the need for fast, "real-time" information on which to base tobacco-related policy decisions. Second, there is a great deal of tacit knowledge held by experts within the Ontario tobacco control community. The networks among government, non-government, and public health organizations are the structures through which tacit knowledge is exchanged. These networks are dynamic, fluid and shifting. There exists a gap in the production and utilization of research knowledge for tobacco control policy. Tacit knowledge held by experts in Ontario tobacco control networks is an integral means of managing and evaluating research knowledge. Finally, this study builds on Weiss's concept of tactical model of evidence use by highlighting the utilization of research to enhance one's credibility.

    User involvement has become a growing importance in healthcare. The United Nations state that adolescents have a right to be heard, and user involvement in healthcare is a legal right in many countries. Some research provides an insight into the field of user involvement in somatic and mental healthcare for adults, but little is known about user involvement in adolescents' mental healthcare, and no overview of the existing research evidence exists. The aim of this systematic review is to provide an overview of existing research reporting on experiences with and the effectiveness and safety issues associated with user involvement for adolescents' mental healthcare at the individual and organisational level. A systematic literature search and assessment of published research in the field of user involvement in adolescents' mental healthcare will be carried out. Established guidelines will be used for data extraction (Cochrane Collaboration guidelines, Strengthening the Reporting of Observational studies in Epidemiology and Critical Appraisal Skills Programme (CASP)), critical appraisal (Cochrane Collaboration guidelines and Pragmatic-Explanatory Continuum Indicator Summary) and reporting of results (Preferred Reporting Items for Systematic reviews and Meta-Analyses, Consolidated Standards of Reporting Trials and CASP). Confidence in the research evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.

    Ntuen, Celestine A.; Park, Eui H.; Deeb, Joseph M.; Kim, Jung H.

    1992-01-01

    The research goal of the Human-Machine Systems Engineering Group was to study the existing handling quality studies in aircraft with sonic to supersonic speeds and power in order to understand information requirements needed for a hypersonic vehicle flight simulator. This goal falls within the NASA task statements: (1) develop flight simulator for hypersonic vehicle; (2) study NASP handling qualities; and (3) study effects of flexibility on handling qualities and on control system performance. Following the above statement of work, the group has developed three research strategies. These are: (1) to study existing handling quality studies and the associated aircraft and develop flight simulation data characterization; (2) to develop a profile for flight simulation data acquisition based on objective statement no. 1 above; and (3) to develop a simulator and an embedded expert system platform which can be used in handling quality experiments for hypersonic aircraft/flight simulation training.

    Prevention and treatment standards are based on evidence obtained in behavioral and clinical research. However, racial and ethnic minorities remain relatively absent from the science that develops these standards. While investigators have successfully recruited participants for individual studies using tailored recruitment methods, these strategies require considerable time and resources. Research registries, typically developed around a disease or condition, serve as a promising model for a targeted recruitment method to increase minority participation in health research. This study assessed the tailored recruitment methods used to populate a health research registry targeting African-American community members. We describe six recruitment methods applied between September 2004 and October 2008 to recruit members into a health research registry. Recruitment included direct (existing studies, public databases, community outreach) and indirect methods (radio, internet, and email) targeting the general population, local universities, and African American communities. We conducted retrospective analysis of the recruitment by method using descriptive statistics, frequencies, and chi-square statistics. During the recruitment period, 608 individuals enrolled in the research registry. The majority of enrollees were African American, female, and in good health. Direct and indirect methods were identified as successful strategies for subgroups. Findings suggest significant associations between recruitment methods and age, presence of existing health condition, prior research participation, and motivation to join the registry. A health research registry can be a successful tool to increase minority awareness of research opportunities. Multi-pronged recruitment approaches are needed to reach diverse subpopulations.

  2. Use and misuse of research in books on sex trafficking: implications for interdisciplinary researchers, practitioners, and advocates.

    PubMed

    Fedina, Lisa

    2015-04-01

    Recent articles have raised important questions about the validity of prevalence data on human trafficking, exposing flawed methodologies behind frequently cited statistics. While considerable evidence points to the fact that human trafficking does exist in the United States and abroad, many sources of literature continue to cite flawed data and some misuse research in ways that seemingly inflate the problem, which can have serious implications for anti-trafficking efforts, including victim services and anti-trafficking legislation and policy. This systematic review reports on the prevalence data used in 42 recently published books on sex trafficking to determine the extent to which published books rely on data estimates and just how they use or misuse existing data. The findings from this review reveal that the vast majority of published books do rely on existing data that were not rigorously produced and therefore may be misleading or at minimum, inaccurate. Implications for practice, research, and policy are discussed, as well as recommendations for future prevalence studies on human trafficking. © The Author(s) 2014.

  3. Toward unification of taxonomy databases in a distributed computer environment

    1994-12-31

    All the taxonomy databases constructed with the DNA databases of the international DNA data banks are powerful electronic dictionaries which aid in biological research by computer. The taxonomy databases are, however not consistently unified with a relational format. If we can achieve consistent unification of the taxonomy databases, it will be useful in comparing many research results, and investigating future research directions from existent research results. In particular, it will be useful in comparing relationships between phylogenetic trees inferred from molecular data and those constructed from morphological data. The goal of the present study is to unify the existent taxonomymore » databases and eliminate inconsistencies (errors) that are present in them. Inconsistencies occur particularly in the restructuring of the existent taxonomy databases, since classification rules for constructing the taxonomy have rapidly changed with biological advancements. A repair system is needed to remove inconsistencies in each data bank and mismatches among data banks. This paper describes a new methodology for removing both inconsistencies and mismatches from the databases on a distributed computer environment. The methodology is implemented in a relational database management system, SYBASE.« less

  19. A scoping review of research on the prescribing practice of Canadian pharmacists

    PubMed Central

    Faruquee, Chowdhury Farhana; Guirguis, Lisa M.

    2015-01-01

    Background: Pharmacists in Canada have been prescribing since 2007. This review aims to explore the volume, array and nature of research activity on Canadian pharmacist prescribing and to identify gaps in the existing literature. Methods: We conducted a scoping review to examine the literature on prescribing by pharmacists in Canada according to methodological trends, research areas and key findings. We searched for peer-reviewed research articles and abstracts in the Ovid MEDLINE, Ovid EMBASE and International Pharmaceutical Abstracts databases without any date limitations. A standardized form was used to extract information. Results: We identified 156 articles; of these, 26 articles and 12 abstracts met inclusion criteria. One-half of the research studies (20) used quantitative methods, including surveys, trials and experimental designs; 11 studies used qualitative methods and 7 used other methods. Research on pharmacist prescribing demonstrated an improvement in patient outcomes (13 studies), varied stakeholder perceptions (10 studies) and factors that influence this practice change (11 studies). Pharmacist prescribing was adopted when pharmacists practised patient-centred care. Stakeholders held contrasting perceptions of pharmacist prescribing. Discussion: Canadian research has demonstrated the benefit of pharmacist prescribing on patient outcomes, which is not present in the international literature. Future research may consider a meta-analysis addressing the impact on patient health. Gaps in research include comparisons between provinces, effects on physicians’ services, overall patient safety and access to health care systems and economic implications for society. Conclusion: A growing body of research on pharmacist prescribing has captured the early impact of prescribing on patient outcomes, perceptions of practice and practice change. Opportunities exist for pan-Canadian research that examines the system impact. PMID:26600824

  1. Technology-Facilitated Sexual Violence: A Literature Review of Empirical Research.

    PubMed

    Henry, Nicola; Powell, Anastasia

    2018-04-01

    Technology-facilitated sexual violence (TFSV) refers to a range of behaviors where digital technologies are used to facilitate both virtual and face-to-face sexually based harms. Such behaviors include online sexual harassment, gender- and sexuality-based harassment, cyberstalking, image-based sexual exploitation, and the use of a carriage service to coerce a victim into an unwanted sexual act. This article reviews the current state of knowledge on these different dimensions, drawing on existing empirical studies. While there is a growing body of research into technology-facilitated harms perpetrated against children and adolescents, there is a dearth of qualitative and quantitative research on TFSV against adults. Moreover, few of the existing studies provide reliable data on the nature, scope, and impacts of TFSV. Preliminary studies, however, indicate that some harms, much like sexual violence more broadly, may be predominantly gender-, sexuality-, and age-based, with young women being overrepresented as victims in some categories. This review collects the empirical evidence to date regarding the prevalence and gender-based nature of TFSV against adults and discusses the implications for policy and programs, as well as suggestions for future research.

  2. Michael Young, the Institute of Community Studies, and the Politics of Kinship.

    PubMed

    Butler, Lise

    2015-01-01

    This article examines the East London-based Institute of Community Studies, and its founder, Michael Young, to show that sociology and social research offered avenues for left-wing political expression in the 1950s. Young, who had previously been Head of the Labour Party Research Department during the Attlee government, drew upon existing currents of psychological and sociological research to emphasize the continuing relevance of the extended family in industrial society and to offer a model of socialist citizenship, solidarity and mutual support not tied to productive work. Young and his colleagues at the Institute of Community Studies promoted the supportive kinship networks of the urban working class, and an idealized conception of the relationships between women, to suggest that family had been overlooked by the left and should be reclaimed as a progressive force. The article shows that the Institute's sociological work was informed by a pre-existing concern with family as a model for cooperative socialism, and suggests that sociology and social research should be seen as important sources of political commentary for scholars of post-war politics.

    Objective To identify unmet research needs of state and community tobacco control practitioners pertaining to electronic nicotine delivery systems (ENDS or e-cigarettes) that would inform policy and practice efforts at the state and community levels, and to describe ENDS-related research and dissemination activities of the National Cancer Institute-funded State and Community Tobacco Control Research Initiative. Methods To determine specific research gaps relevant to state and community tobacco control practice, we analysed survey data collected from tobacco control programmes (TCPs) in all 50 US states and the District of Columbia (N=51). Survey items covered a range of ENDS issues: direct harm to users, harm of secondhand vapour, cessation, flavours, constituents and youth access. Results There is no ENDS topic on which a majority of state TCP managers feel very informed. They feel least informed about harms of secondhand vapour while also reporting that this information is among the most important for their programme. A majority (N=31) of respondents indicated needs for research on the implications of ENDS products for existing policies. Conclusions TCP managers report that ENDS research is highly important for practice and need research-based information to inform decision making around the inclusion of ENDS in existing tobacco control policies. For optimal relevance to state and community TCPs, research on ENDS should prioritise study of the health effects of ENDS use and secondhand exposure to ENDS vapour in the context of existing tobacco control policies.

    This paper suggests that a methodology exists for selecting optimum organizations for future space communities of various sizes and purposes. Results of an exploratory study to identify an optimum hypothetical organizational structure for a large earth-orbiting multidisciplinary research and applications (R&A) Space Base manned by a mixed crew of technologists are presented. Since such a facility does not presently exist, in situ empirical testing was not possible. Study activity was, therefore, concerned with the identification of a desired organizational structural model rather than the empirical testing of it. The principal finding of this research was that a four-level project type 'total matrix' model will optimize the effectiveness of Space Base technologists. An overall conclusion which can be reached from the research is that application of this methodology, or portions of it, may provide planning insights for the formal organizations which will be needed during the Space Industrialization Age.

  8. Assessing the Expected Value of Research Studies in Reducing Uncertainty and Improving Implementation Dynamics.

    With low implementation of cost-effective health technologies being a problem in many health systems, it is worth considering the potential effects of research on implementation at the time of health technology assessment. Meaningful and realistic implementation estimates must be of dynamic nature. To extend existing methods for assessing the value of research studies in terms of both reduction of uncertainty and improvement in implementation by considering diffusion based on expert beliefs with and without further research conditional on the strength of evidence. We use expected value of sample information and expected value of specific implementation measure concepts accounting for the effects of specific research studies on implementation and the reduction of uncertainty. Diffusion theory and elicitation of expert beliefs about the shape of diffusion curves inform implementation dynamics. We illustrate use of the resulting dynamic expected value of research in a preterm birth screening technology and results are compared with those from a static analysis. Allowing for diffusion based on expert beliefs had a significant impact on the expected value of research in the case study, suggesting that mistakes are made where static implementation levels are assumed. Incorporating the effects of research on implementation resulted in an increase in the expected value of research compared to the expected value of sample information alone. Assessing the expected value of research in reducing uncertainty and improving implementation dynamics has the potential to complement currently used analyses in health technology assessments, especially in recommendations for further research. The combination of expected value of research, diffusion theory, and elicitation described in this article is an important addition to the existing methods of health technology assessment.

  14. Formative research on the primo vascular system and acceptance by the korean scientific community: the gap between creative basic science and practical convergence technology.

    PubMed

    Kim, Hoon Gi

    2013-12-01

    The purpose of this study was to trace the formative process of primo vascular system (PVS) research over the past decade and to describe the characteristics of the Korean scientific community. By publishing approximately 30 papers in journals ranking in the Science Citation Index (Expanded), the PVS research team actively convinced domestic and international scientists of the anatomical existence of the PVS and its possible application to Korean and Western medicine. In addition, by sharing the PVS observation technique, the team promoted the dissemination and further pursuit of the research. In 2012, however, PVS researchers performed smaller scale research without advancing to a higher level as compared to the early days. The main reasons were found to be the Korean Research and Development policy of supporting creative, small-scale basic research and applied research of Western scientific fields that promised potentially greater success on an extensive scale; the indifference concerning, and the disbelief in, the existence of a new circulatory system were shown by the Western medical community. In addition, the Oriental medical community was apathetic about working with the PVS team. Professors Kwang-Sup Soh and Byung-Cheon Lee were the prime movers of PVS research under difficult conditions. Spurred by their belief in the existence and significance of the PVS, they continued with their research despite insufficient experimental data. The Korean scientific community is not ready to promote the Korea-oriented creative field of the PVS team. Copyright © 2013. Published by Elsevier B.V.

    2013-01-01

    PARTICLE_RISK was one of the first multidisciplinary projects funded by the European Commission's Framework Programme that was responsible for evaluating the implications of nanomaterial (NM) exposure on human health. This project was the basis for this review which identifies the challenges that exist within the assessment of NM risk. We have retrospectively reflected on the findings of completed nanotoxicology studies to consider what progress and advances have been made within the risk assessment of NMs, as well as discussing the direction that nanotoxicology research is taking and identifying the limitations and failings of existing research. We have reflected on what commonly encountered challenges exist and explored how these issues may be resolved. In particular, the following is discussed (i) NM selection (ii) NM physico-chemical characterisation; (iii) NM dispersion; (iv) selection of relevant doses and concentrations; (v) identification of relevant models, target sites and endpoints; (vi) development of alternatives to animal testing; and (vii) NM risk assessment. These knowledge gaps are relatively well recognised by the scientific community and recommendations as to how they may be overcome in the future are provided. It is hoped that this will help develop better defined hypothesis driven research in the future that will enable comprehensive risk assessments to be conducted for NMs. Importantly, the nanotoxicology community has responded and adapted to advances in knowledge over recent years to improve the approaches used to assess NM hazard, exposure and risk. It is vital to learn from existing information provided by ongoing or completed studies to avoid unnecessary duplication of effort, and to offer guidance on aspects of the experimental design that should be carefully considered prior to the start of a new study.

  4. A critical methodological review of discourse and conversation analysis studies of family therapy.

    PubMed

    Tseliou, Eleftheria

    2013-12-01

    Discourse (DA) and conversation (CA) analysis, two qualitative research methods, have been recently suggested as potentially promising for the study of family therapy due to common epistemological adherences and their potential for an in situ study of therapeutic dialog. However, to date, there is no systematic methodological review of the few existing DA and CA studies of family therapy. This study aims at addressing this lack by critically reviewing published DA and CA studies of family therapy on methodological grounds. Twenty-eight articles in total are reviewed in relation to certain methodological axes identified in the relevant literature. These include choice of method, framing of research question(s), data/sampling, type of analysis, epistemological perspective, content/type of knowledge claims, and attendance to criteria for good quality practice. It is argued that the reviewed studies show "glimpses" of the methods' potential for family therapy research despite the identification of certain "shortcomings" regarding their methodological rigor. These include unclearly framed research questions and the predominance of case study designs. They also include inconsistencies between choice of method, stated or unstated epistemological orientations and knowledge claims, and limited attendance to criteria for good quality practice. In conclusion, it is argued that DA and CA can add to the existing quantitative and qualitative methods for family therapy research. They can both offer unique ways for a detailed study of the actual therapeutic dialog, provided that future attempts strive for a methodologically rigorous practice and against their uncritical deployment. © FPI, Inc.

  5. Theoretical models of parental HIV disclosure: a critical review.

    PubMed

    Qiao, Shan; Li, Xiaoming; Stanton, Bonita

    2013-01-01

    This study critically examined three major theoretical models related to parental HIV disclosure (i.e., the Four-Phase Model [FPM], the Disclosure Decision Making Model [DDMM], and the Disclosure Process Model [DPM]), and the existing studies that could provide empirical support to these models or their components. For each model, we briefly reviewed its theoretical background, described its components and/or mechanisms, and discussed its strengths and limitations. The existing empirical studies supported most theoretical components in these models. However, hypotheses related to the mechanisms proposed in the models have not yet tested due to a lack of empirical evidence. This study also synthesized alternative theoretical perspectives and new issues in disclosure research and clinical practice that may challenge the existing models. The current study underscores the importance of including components related to social and cultural contexts in theoretical frameworks, and calls for more adequately designed empirical studies in order to test and refine existing theories and to develop new ones.

    2018-04-01

    The proliferation of robotic technologies in recent years brings robots closer to humanities. There are many researches on going at various stages of development to bring robots into our homes, schools, nurseries, elderly care centres, offices, hospitals and factories. With recently developed robots having tendency to have appearance which increasingly displaying similarities to household animals and humans, there is a need to study the existence of uncanny valley phenomenon. Generally, the acceptance of people toward robots increases as the robots acquire increasing similarities to human features until a stage where people feel very uncomfortable, eerie, fear and disgust when the robot appearance become almost human like but not yet human. This phenomenon called uncanny valley was first reported by Masahiro Mori. There are numerous researches conducted to measure the existence of uncanny valley in Japan and European countries. However, there is limited research reported on uncanny valley phenomenon in Malaysia so far. In view of the different cultural background and exposure of Malaysian population to robotics technology compared to European or East Asian populations, it is worth to study this phenomenon in Malaysian context. The main aim of this work is to conduct a preliminary study to determine the existence of uncanny valley phenomenon in Malaysian urban and rural populations. It is interesting to find if there are any differences in the acceptance of the two set of populations despite of their differences. Among others the urban and rural populations differ in term of the rate of urbanization and exposure to latest technologies. A set of four interactive robotic faces and an ideal human model representing the fifth robot are used in this study. The robots have features resembling a cute animal, cartoon character, typical robot and human-like. Questionnaire surveys are conducted on respondents from urban and rural populations. Survey data collected are analysed to determine the preferred features in a humanoid robot, the acceptance of respondents toward the robotic faces and the existence of uncanny valley phenomenon. Based on the limited study, it is found that the uncanny valley phenomenon existed in both the Malaysian urban and rural population.

    Bouck, Emily C; Flanagan, Sara M

    2016-11-01

    This study sought to understand the extent to which students with severe disabilities receive assistive technology in school and out-of-school, and the relationship between receipt of assistive technology in school and post-school outcomes for these students. This study was a secondary analysis of the National Longitudinal Transition Study-2 (NLTS2) from the USA. To analyze the data in this correlational study, researchers conducted frequency distributions, Chi Square Tests of Associations, significance tests and logistic regressions. The main results suggest (a) receipt of assistive technology in school varied greatly by disability identification; (b) receipt of assistive technology post-school also varied by disability identification, but receipt was generally lower; and (c) few statistically significant post-school outcome differences existed between students who received assistive technology and those who did not. An under-utilization of assistive technology exists in practice in the USA for students with severe disabilities. Implications for Rehabilitation An under-utilization of assistive technology for secondary students and adults with severe disabilities likely exists. A need exists for improved collaboration between professionals in rehabilitation and professionals in schools to ensure continuation of needed services or aids, such as assistive technology. Additional research is needed to better understand the adult life (or post-school) outcomes of individuals with severe disabilities, factors from PK-12 schooling or post-school services that positively and negative impact those outcomes.

    2008-01-01

    No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed.

    2016-07-01

    A gap in information about pediatric clinical trials exists, and parents remain uncertain about what is involved in research studies involving children. We aimed to understand parent perspectives about pediatric clinical research after viewing the online Children and Clinical Studies (CaCS) program. Using a qualitative descriptive study design, we conducted focus groups with parents and phone interviews with physicians. Three themes emerged providing approaches to improve parent's understanding of clinical research by including strategies where parents (a) hear from parents like themselves to learn about pediatric research, (b) receive general clinical research information to complement study-specific details, and (c) are provided more information about the role of healthy child volunteers. Parents found the website a valuable tool that would help them make a decision about what it means to participate in research. This tool can assist parents, providers, and researchers by connecting general information with study-specific information. © The Author(s) 2015.

    2015-12-01

    Biological network alignment aims to find regions of topological and functional (dis)similarities between molecular networks of different species. Then, network alignment can guide the transfer of biological knowledge from well-studied model species to less well-studied species between conserved (aligned) network regions, thus complementing valuable insights that have already been provided by genomic sequence alignment. Here, we review computational challenges behind the network alignment problem, existing approaches for solving the problem, ways of evaluating their alignment quality, and the approaches' biomedical applications. We discuss recent innovative efforts of improving the existing view of network alignment. We conclude with open research questions in comparative biological network research that could further our understanding of principles of life, evolution, disease, and therapeutics.

  3. Cultivating cohort studies for observational translational research.

    PubMed

    Ransohoff, David F

    2013-04-01

    "Discovery" research about molecular markers for diagnosis, prognosis, or prediction of response to therapy has frequently produced results that were not reproducible in subsequent studies. What are the reasons, and can observational cohorts be cultivated to provide strong and reliable answers to those questions? Experimental Selected examples are used to illustrate: (i) what features of research design provide strength and reliability in observational studies about markers of diagnosis, prognosis, and response to therapy? (ii) How can those design features be cultivated in existing observational cohorts, for example, within randomized controlled clinical trial (RCT), other existing observational research studies, or practice settings like health maintenance organization (HMOs)? Examples include a study of RNA expression profiles of tumor tissue to predict prognosis of breast cancer, a study of serum proteomics profiles to diagnose ovarian cancer, and a study of stool-based DNA assays to screen for colon cancer. Strengths and weaknesses of observational study design features are discussed, along with lessons about how features that help assure strength might be "cultivated" in the future. By considering these examples and others, it may be possible to develop a process of "cultivating cohorts" in ongoing RCTs, observational cohort studies, and practice settings like HMOs that have strong features of study design. Such an effort could produce sources of data and specimens to reliably answer questions about the use of molecular markers in diagnosis, prognosis, and response to therapy.

In human ethics, researchers need to justify why the use of humans is necessary should suitable models exist. Conversely, in animal ethics, a researcher must justify why research cannot be carried out on suitable alternatives. In the case of medical procedures or therapeutics testing, the use of animal models is often justified. However, in forensic research, the justification may be less evident, particularly when research involves the infliction of trauma on living animals. To determine how the forensic science community is dealing with this dilemma, a review of literature within major forensic science journals was conducted. The frequency and trends of the use of animals in forensic science research was investigated for the period 1 January 2012-31 December 2016. The review revealed 204 original articles utilizing 5050 animals in various forms as analogues for human tissue. The most common specimens utilized were various species of rats (35.3%), pigs (29.3%), mice (17.7%), and rabbits (8.2%) although different specimens were favored in different study themes. The majority of studies (58%) were conducted on post-mortem specimens. It is, however, evident that more needs to be done to uphold the basic ethical principles of reduction, refinement and replacement in the use of animals for research purposes.

  5. Nursing students' attitudes toward science in the nursing curricula

    NASA Astrophysics Data System (ADS)

    Maroo, Jill Deanne

    The nursing profession combines the art of caregiving with scientific concepts. Nursing students need to learn science in order to start in a nursing program. However, previous research showed that students left the nursing program, stating it included too much science (Andrew et al., 2008). Research has shown a correlation between students' attitudes and their performance in a subject (Osborne, Simon, & Collins, 2003). However, little research exists on the overall attitude of nursing students toward science. At the time of my study there existed no large scale quantitative study on my topic. The purpose of my study was to identify potential obstacles nursing students face, specifically, attitude and motivation toward learning science. According to research the nation will soon face a nursing shortage and students cite the science content as a reason for not completing the nursing program. My study explored nursing students' attitudes toward science and reasons these students are motivated to learn science. I ran a nationwide mixed methods approach with 1,402 participants for the quantitative portion and 4 participants for the qualitative portion. I validated a questionnaire in order to explore nursing students' attitudes toward science, discovered five different attitude scales in that questionnaire and determined what demographic factors provided a statistically significant prediction of a student's score. In addition, I discovered no statistical difference in attitude exists between students who have the option of taking nursing specific courses and those who do not have that option. I discovered in the qualitative interviews that students feel science is necessary in nursing but do not feel nurses are scientists. My study gives a baseline of the current attitude of nursing students toward science and why these students feel the need to learn the science.

    Objective We compare 5 health informatics research projects that applied community-based participatory research (CBPR) approaches with the goal of extending existing CBPR principles to address issues specific to health informatics research. Materials and methods We conducted a cross-case analysis of 5 diverse case studies with 1 common element: integration of CBPR approaches into health informatics research. After reviewing publications and other case-related materials, all coauthors engaged in collaborative discussions focused on CBPR. Researchers mapped each case to an existing CBPR framework, examined each case individually for success factors and barriers, and identified common patterns across cases. Results Benefits of applying CBPR approaches to health informatics research across the cases included the following: developing more relevant research with wider impact, greater engagement with diverse populations, improved internal validity, more rapid translation of research into action, and the development of people. Challenges of applying CBPR to health informatics research included requirements to develop strong, sustainable academic-community partnerships and mismatches related to cultural and temporal factors. Several technology-related challenges, including needs to define ownership of technology outputs and to build technical capacity with community partners, also emerged from our analysis. Finally, we created several principles that extended an existing CBPR framework to specifically address health informatics research requirements. Conclusions Our cross-case analysis yielded valuable insights regarding CBPR implementation in health informatics research and identified valuable lessons useful for future CBPR-based research. The benefits of applying CBPR approaches can be significant, particularly in engaging populations that are typically underserved by health care and in designing patient-facing technology.

    The ability to record and stream neurosurgery is an unprecedented opportunity to further research, medical education, and quality improvement. Here, we appraise the ease of implementation of existing point-of-view devices when capturing and sharing procedures from the neurosurgical operating room and detail their potential utility in this context. Our neurosurgical team tested and critically evaluated features of the Google Glass and Panasonic HX-A500 cameras, including ergonomics, media quality, and media sharing in both the operating theater and the angiography suite. Existing devices boast several features that facilitate live recording and streaming of neurosurgical procedures. Given that their primary application is not intended for the surgical environment, we identified a number of concrete, yet improvable, limitations. The present study suggests that neurosurgical video capture and live streaming represents an opportunity to contribute to research, education, and quality improvement. Despite this promise, shortcomings render existing devices impractical for serious consideration. We describe the features that future recording platforms should possess to improve upon existing technology.

    Participatory approaches to qualitative research practice constantly change in response to evolving research environments. Researchers are increasingly encouraged to undertake secondary analysis of qualitative data, despite epistemological and ethical challenges. Interpretive focus groups can be described as a more participative method for groups to analyse qualitative data. To facilitate interpretive focus groups with women in Papua New Guinea to extend analysis of existing qualitative data and co-create new primary data. The purpose of this was to inform a transformational grounded theory and subsequent health promoting action. A two-step approach was used in a grounded theory study about how women experience male circumcision in Papua New Guinea. Participants analysed portions or 'chunks' of existing qualitative data in story circles and built upon this analysis by using the visual research method of storyboarding. New understandings of the data were evoked when women in interpretive focus groups analysed the data 'chunks'. Interpretive focus groups encouraged women to share their personal experiences about male circumcision. The visual method of storyboarding enabled women to draw pictures to represent their experiences. This provided an additional focus for whole-of-group discussions about the research topic. Interpretive focus groups offer opportunity to enhance trustworthiness of findings when researchers undertake secondary analysis of qualitative data. The co-analysis of existing data and co-generation of new data between research participants and researchers informed an emergent transformational grounded theory and subsequent health promoting action.

    1997-08-01

    Although the complexity of undertaking qualitative research with non-English speaking informants has become increasingly recognized, few empirical studies exist which explore the influence of translation on the findings of the study. The aim of this exploratory study was therefore to examine the influence of translation on the reliability and validity of the findings of a qualitative research study. In-depth interviews were undertaken in Cantonese with a convenience sample of six women to explore their perceptions of factors influencing their uptake of Pap smears. Data analysis involved three stages. The first stage involved the translation and transcription of all the interviews into English independently by two translators as well as transcription into Chinese by a third researcher. The second stage involved content analysis of the three data sets to develop categories and themes and the third stage involved a comparison of the categories and themes generated from the Chinese and English data sets. Despite no significant differences in the major categories generated from the Chinese and English data, some minor differences were identified in the themes generated from the data. More significantly the results of the study demonstrated some important issues to consider when using translation in qualitative research, in particular the complexity of managing data when no equivalent word exists in the target language and the influence of the grammatical style on the analysis. In addition the findings raise questions about the significance of the conceptual framework of the research design and sampling to the validity of the study. The importance of using only one translator to maximize the reliability of the study was also demonstrated. In addition the author suggests the findings demonstrate particular problems in using translation in phenomenological research designs.

    Here, this work presents a new approach for analysing the ability of existing research metrics to identify research which has strongly influenced future developments. More specifically, we focus on the ability of citation counts and Mendeley reader counts to distinguish between publications regarded as seminal and publications regarded as literature reviews by field experts. The main motivation behind our research is to gain a better understanding of whether and how well the existing research metrics relate to research quality. For this experiment we have created a new dataset which we call TrueImpactDataset and which contains two types of publications, seminalmore » papers and literature reviews. Using the dataset, we conduct a set of experiments to study how citation and reader counts perform in distinguishing these publication types, following the intuition that causing a change in a field signifies research quality. Finally, our research shows that citation counts work better than a random baseline (by a margin of 10%) in distinguishing important seminal research papers from literature reviews while Mendeley reader counts do not work better than the baseline.« less

    To describe a new conceptual framework and the research protocol of a study designed to examine the quality of life in stroke survivor-caregiver dyads. Stroke has a significant impact on the patient-caregiver dyad. Few studies have been guided by a specific conceptual framework which considers the interactions among pre-existing situations prior to stroke, the new situation caused by the stroke and the moderating effects of environmental and caregiver-related variables. Longitudinal study. A sample of stroke survivor-caregiver dyads will be enrolled at patient discharge from rehabilitation hospitals and will be surveyed every 3 months for 1-year. Hypotheses generated from the conceptual framework will test predictors, mediators and moderators of stroke survivor and caregiver quality of life from the pre-existing situation prior to the stroke, the new situation mediation poststroke and situation moderators. The study is supported by a grant from the Centre of Excellence for Nursing Scholarship, Rome, December 2013. This study seeks to identify variables in the pre-existing situation prior to the stroke (e.g. living condition), the new situation mediation poststroke (e.g. type of stroke and caregiver burden) as well as situation moderators (e.g. social support) that influence stroke survivor-caregiver dyad's quality of life across the stroke trajectory. Also, the study will inform clinical practice and research by identifying variables that are potentially modifiable and therefore amenable to intervention. The proposed framework will also be helpful for future research focused on stroke survivor-caregiver dyads. © 2014 John Wiley & Sons Ltd.

    2017-06-15

    Evidence highlights a high prevalence of common mental health disorders in armed forces veterans and their families, with depression, anxiety, alcohol misuse and anger being more common than PTSD. This paper presents a protocol for a systematic review and meta-analysis to identify existing randomised controlled trial (RCT) research testing the effectiveness of psychological interventions for these difficulties in armed forces veterans and their family members. Electronic databases (CENTRAL, PsycInfo, MEDLINE, CINAHL, The Cochrane Register of Clinical Trials, EMBASE and ASSIA) will be searched to identify suitable studies for inclusion in the review supplemented by forward and backward reference checking, grey literature searches and contact with subject authors. Research including armed forces veterans and their family members will be included in the review with research including serving personnel or individuals under the age of 18 being excluded. Few RCTs examining the treatment of depression, anxiety, alcohol misuse or anger exist in armed forces veterans to date. The primary outcome will be symptomatic change following intervention for these difficulties. The secondary outcomes will include methodological aspects of interest such as discharge type and recruitment setting if data permits. In the event that the number of studies identified is too low to undertake a meta-analysis, a narrative review will be conducted. Quality assessment will be undertaken using the Cochrane Collaboration Tool and Cochran's Q statistic calculated to test for heterogeneity as suggested by the Cochrane handbook. The review will examine the findings of existing intervention research for depression, anxiety, alcohol misuse or anger in armed forces veterans and their families, along with any effect sizes that may exist.

    In Bolivia, there is increasing interest in incorporating research ethics into study procedures, but there have been inconsistent application of research ethics practices. Minimal data exist regarding the experiences of researchers concerning the ethical conduct of research. A cross-sectional study was administered to Bolivian health leaders with research experience (n = 82) to document their knowledge, perceptions, and experiences of research ethics committees and infrastructure support for research ethics. Results showed that 16% of respondents reported not using ethical guidelines to conduct their research and 66% indicated their institutions did not consistently require ethics approval for research. Barriers and facilitators to incorporate research ethics into practice were outlined. These findings will help inform a comprehensive rights-based research ethics education program in Bolivia. © The Author(s) 2015.

    A number of projects exist that are investigating the ability to restore visual percepts for individuals who are blind through a visual prosthesis. While many projects have reported the results from a technical basis, very little exists in the professional literature on the human experience of visual implant technology. The current study uses an ethnographic methodological approach to document the experiences of the research participants and study personnel of a optic nerve vision prosthesis project in Brussels, Belgium. The findings have implications for motivation for participating in clinical trials, ethical safeguards of participants and the role of the participant in a research study. Implications for Rehabilitation Rehabilitation practitioners are often solicited by prospective participants to assist in evaluating a clinical trial before making a decision about participation. Rehabilitation professionals should be aware that: The decision to participate in a clinical trial is ultimately up to the individual participant. However, participants should be aware that family members might experience stress from of a lack of knowledge about the research study. The more opportunities a participant has to share thoughts and feelings about the research study with investigators will likely result in a positive overall experience. Ethical safeguards put in place to protect the interests of an individual participant may have the opposite effect and create stress. Rehabilitation professionals can play an important role as participant advocates from recruitment through termination of the research study. Participant hope is an important component of participation in a research study. Information provided to participants by investigators during the consent process should be balanced carefully with potential benefits, so it does not destroy a participant's hope.

    Brogt, Erik; Foster, Tom; Dokter, Erin; Buxner, Sanlyn; Antonellis, Jessie

    We present an argument for, and suggested implementation of, a code of ethics for the astronomy education research community. This code of ethics is based on legal and ethical considerations set forth by U.S. federal regulations and the existing code of conduct of the American Educational Research Association. We also provide a fictitious research study as an example for working through the suggested code of ethics.

    Although social support is a frequently cited enabler of physical activity, few studies have examined how to harness social support in interventions. This paper describes community-based formative research to design a walking program for mobilizing naturally occurring social networks to support increases in walking behavior. Focus group methods were used to engage community members in discussions about desired walking program features. The research was conducted with underserved communities in Sumter County, South Carolina. The majority of focus group participants were women (76%) and African American (92%). Several important themes emerged from the focus group results regarding attitudes toward walking, facilitators of and barriers to walking, ideal walking program characteristics, and strategies for encouraging community members to walk. Most noteably, the role of existing social networks as a supportive influence on physical activity was a recurring theme in our formative research and a gap in the existing evidence base. The resulting walking program focused on strategies for mobilizing, supporting and reinforcing existing social networks as mechanisms for increasing walking. Our approach to linking theory, empirical evidence and community-based formative research for the development of a walking intervention offers an example for practitioners developing intervention strategies for a wide range of behaviors.

  14. [How can the impact of Health Technology Assessment (HTA) in the Austrian healthcare system be assessed? Design of a conceptual framework].

    PubMed

    Schumacher, I; Zechmeister, I

    2012-04-01

    In Austria research in Health Technology Assessment (HTA) has been conducted since the 1990s. Research in HTA aims at supporting an adequate and efficient use of health care resources in order to sustain a publicly financed and solidary health care system. Ultimately, HTA research should result in better health of the population. Research results should provide independent information for decision makers. For legitimizing further research resources and for prioritizing future HTA research and guaranteeing the value of future research, HTA research needs itself to undergo evaluation. Aim of the study is to design a conceptual framework for evaluating the impact of HTA research in Austria on the basis of the existing literature. An already existing review which presents methods and concepts how to evaluate HTA-impact was updated by a systematic research including literature of the years 2004-January 2010. Results were analysed in regard to 4 categories: definition of the term impact, target groups and system levels, operationalisation of indicators and evaluation methods. Overall, 19 publications were included. Referring to the 4 categories, an explanation of impact has to take into account HTAs multidisciplinary setting and needs a context related definition. Target groups, system levels, indicators and methods depend on the impact defined. Studies investigated direct and indirect impact and were focused on different target groups like physicians, nurses and decision makers on the micro-, and meso level, as well as politicians and reimbursement institutions on the macro level. Except for one reference all studies applied already known and mostly qualitative methods for measuring the impact of HTA research. Thus, an appropriate pool of instruments seems to be available. There is a lack of information about validity of applied methods and indicators. By adapting adequate methods and concepts a conceptual framework for the Austrian HTA-Impact evaluation has been designed. The paper presents an overview of existing methods for the evaluation of the HTA research. This has been used to identify useful approaches for measuring the HTA-impact in Austria. By providing a context sensitive framework for impact evaluation in Austria the Austrian HTA-research contributes to the international trend of impact-evaluation. © Georg Thieme Verlag KG Stuttgart · New York.

    Recent studies have reported gender differences in research grant applications and funding outcomes for medical school faculty. Our goal was to determine whether similar patterns exist at the resident level and, if so, to explore possible explanations. We conducted a retrospective review of all applications to an internal, mentored research grant fund at a large academic pediatric residency program from 2003 to 2008. We determined whether gender differences existed for application characteristics and outcomes and defined significant predictors of success. During the 5-year period, the fund supported 42 (66%) of 64 applications. Among all applicants, men were more likely than women to hold an advanced research degree. Men requested more money than women and obtained more favorable application scores. Funding success rates were not statistically different between male and female applicants. Among funded applicants, men received higher awards than women, although the percentage of requests funded was the same. In a multiple regression analysis, advanced degree was the significant independent predictor of successful funding outcome. Controlling for advanced degree attenuated the association between gender and timing of application, type of project, dollars requested, and dollars awarded; however, even after controlling for advanced degree, women had inferior grant scores compared with men. Gender differences existed in research grant applications and funding among pediatric residents that mirrored faculty patterns. Among residents, these differences were explained in part by the correlation of male gender with holding an advanced research degree.

  16. The Impact of the Birth of a Child with Intellectual Disabilities on Pre-Existing Parental Christian Faith from the Perspective of Parents Who Have Parented Their Child to Adulthood.

    2015-11-01

    Faith in the lives of UK families with an adult with intellectual disabilities is an under-researched area with little existing literature. Research in the United States with Christian parents suggests that they draw on their faith for coping (Rogers-Dulan 1998) and for understanding (Skinner et al. 1999). In this study, grounded theory methodology has been used to examine the impact on pre-existing parental faith of the birth of a child with intellectual disabilities from the perspective of parents who have parented their children to adulthood. Seventeen parents or couples took part in semistructured qualitative interviews about their faith. The majority of parents after their child were diagnosed with intellectual disabilities went through a period of flux when they questioned the role of God in the disability. The positive or negative connotations of the attempts at meaning-making did not impact on the eventual outcome for the parents. They eventually put such existential questions aside, accepted their child, and continued in their faith. The implications of the research for health professionals, church organizations and researchers are considered. © 2015 John Wiley & Sons Ltd.

    In a cloud computing paradigm, energy efficient allocation of different virtualized ICT resources (servers, storage disks, and networks, and the like) is a complex problem due to the presence of heterogeneous application (e.g., content delivery networks, MapReduce, web applications, and the like) workloads having contentious allocation requirements in terms of ICT resource capacities (e.g., network bandwidth, processing speed, response time, etc.). Several recent papers have tried to address the issue of improving energy efficiency in allocating cloud resources to applications with varying degree of success. However, to the best of our knowledge there is no published literature on this subjectmore » that clearly articulates the research problem and provides research taxonomy for succinct classification of existing techniques. Hence, the main aim of this paper is to identify open challenges associated with energy efficient resource allocation. In this regard, the study, first, outlines the problem and existing hardware and software-based techniques available for this purpose. Furthermore, available techniques already presented in the literature are summarized based on the energy-efficient research dimension taxonomy. The advantages and disadvantages of the existing techniques are comprehensively analyzed against the proposed research dimension taxonomy namely: resource adaption policy, objective function, allocation method, allocation operation, and interoperability.« less

  18. An assessment of survey measures used across key epidemiologic studies of United States Gulf War I Era Veterans

    PubMed Central

    2013-01-01

    Over the past two decades, 12 large epidemiologic studies and 2 registries have focused on U.S. veterans of the 1990–1991 Gulf War Era. We conducted a review of these studies’ research tools to identify existing gaps and overlaps of efforts to date, and to advance development of the next generation of Gulf War Era survey tools. Overall, we found that many of the studies used similar instruments. Questions regarding exposures were more similar across studies than other domains, while neurocognitive and psychological tools were the most variable. Many studies focused on self-reported survey results, with a range of validation practices. However, physical exams, biomedical assessments, and specimen storage were not common. This review suggests that while research may be able to pool data from past surveys, future surveys need to consider how their design can yield data comparable with previous surveys. Additionally, data that incorporate recent technologies in specimen and genetic analyses would greatly enhance such survey data. When combined with existing data on deployment-related exposures and post-deployment health conditions, longitudinal follow-up of existing studies within this collaborative framework could represent an important step toward improving the health of veterans.

    2018-01-03

    Recent advances in biomedical research have generated a large volume of drug-related data. To effectively handle this flood of data, many initiatives have been taken to help researchers make good use of them. As the results of these initiatives, many drug knowledge bases have been constructed. They range from simple ones with specific focuses to comprehensive ones that contain information on almost every aspect of a drug. These curated drug knowledge bases have made significant contributions to the development of efficient and effective health information technologies for better health-care service delivery. Understanding and comparing existing drug knowledge bases and how they are applied in various biomedical studies will help us recognize the state of the art and design better knowledge bases in the future. In addition, researchers can get insights on novel applications of the drug knowledge bases through a review of successful use cases. In this study, we provide a review of existing popular drug knowledge bases and their applications in drug-related studies. We discuss challenges in constructing and using drug knowledge bases as well as future research directions toward a better ecosystem of drug knowledge bases. © The Author(s) 2018.

    Seven studies have been conducted on research in the existence and nature of solutions of the restricted problems of three and four bodies. The details and results of five of these research investigations have already been published, and the latest two studies will be published shortly. A complete bibliography of publications is included in this report. This research has been primarily qualitative and has yielded new information on the behavior of trajectories near the libration points in the Earth-Moon-Sun and Sun-Jupiter-Saturn systems, and on the existence of periodic trajectories about the libration points of the circular and elliptical restricted four-body models. We have also implemented Birkhoff's normalization process for conservative and nonconservative Hamiltonian systems with equilibrium points. This makes available a technique for analyzing stability properties of certain nonlinear dynamical systems, and we have applied this technique to the circular and elliptical restricted three-body models. A related study was also conducted to determine the feasibility of using cislunar periodic trajectories for various space missions. Preliminary results suggest that this concept is attractive for space flight safety operations in cislunar space. Results of this research will be of interest to mathematicians, particularly those working in ordinary differential equations, dynamical systems and celestial mechanics; to astronomers; and to space guidance and mission analysts.

    The widespread use of web searches in daily life has allowed researchers to study people's online social and psychological behavior. Using web search data has advantages in terms of data objectivity, ecological validity, temporal resolution, and unique application value. This review integrates existing studies on web search data that have explored topics including sexual behavior, suicidal behavior, mental health, social prejudice, social inequality, public responses to policies, and other psychosocial issues. These studies are categorized as descriptive, correlational, inferential, predictive, and policy evaluation research. The integration of theory-based hypothesis testing in future web search research will result in even stronger contributions to social psychology.

    There is limited information about how transgender, gender diverse, and Two-Spirit (trans) people have been represented and studied by researchers. The objectives of this study are to (1) map and describe trans research in the social sciences, sciences, humanities, health, education, and business, (2) identify evidence gaps and opportunities for more responsible research with trans people, (3) assess the use of text mining for study identification, and (4) increase access to trans research for key stakeholders through the creation of a web-based evidence map. Study design was informed by community consultations and pilot searches. Eligibility criteria were established to include all original research of any design, including trans people or their health information, and published in English in peer-reviewed journals. A complex electronic search strategy based on relevant concepts in 15 databases was developed to obtain a broad range of results linked to transgender, gender diverse, and Two-Spirit individuals and communities. Searches conducted in early 2015 resulted in 25,242 references after removal of duplicates. Based on the number of references, resources, and an objective to capture upwards of 90% of the existing literature, this study is a good candidate for text mining using Latent Dirichlet Allocation to improve efficiency of the screening process. The following information will be collected for evidence mapping: study topic, study design, methods and data sources, recruitment strategies, sample size, sample demographics, researcher name and affiliation, country where research was conducted, funding source, and year of publication. The proposed research incorporates an extensive search strategy, text mining, and evidence map; it therefore has the potential to build on knowledge in several fields. Review results will increase awareness of existing trans research, identify evidence gaps, and inform strategic research prioritization. Publishing the map online will improve access to research for key stakeholders including community members, policy makers, and healthcare providers. This study will also contribute to knowledge in the area of text mining for study identification by providing an example of how semi-automation performs for screening on title and abstract and on full text.

    Falls and fall-related injuries are major incidents, especially for elderly people, which often mark the onset of major deterioration of health. More than one-third of home-dwelling people aged 65 or above and two-thirds of those in residential care fall once or more each year. Reliable fall detection, as well as prevention, is an important research topic for monitoring elderly living alone in residential or hospital units. The aim of this study is to review the existing fall detection systems and some of the key research challenges faced by the research community in this field. We categorize the existing platforms into two groups: wearable and ambient devices; the classification methods are divided into rule-based and machine learning techniques. The relative merit and potential drawbacks are discussed, and we also outline some of the outstanding research challenges that emerging new platforms need to address.

    2010-07-01

    Many studies of sexual messages in media utilize content analysis methods. At times, this research assumes that researchers and trained coders using content analysis methods and the intended audience view and interpret media content similarly. This article compares adolescents' perceptions of the presence or absence of sexual content on television to those of researchers using three different coding schemes. Results from this formative research study suggest that participants and researchers are most likely to agree with content categories assessing manifest content, and that differences exist among adolescents who view sexual messages on television. Researchers using content analysis methods to examine sexual content in media and media effects on sexual behavior should consider identifying how audience characteristics may affect interpretation of content and account for audience perspectives in content analysis study protocols when appropriate for study goals.

    Perhaps more than any other science discipline-based education research field, the scholarly literature base describing and documenting astronomy education research is highly fragmented and widely dispersed across numerous journals. The resulting wide diversity of journals that publish astronomy education research presents an arduous challenge for scholars trying to best understand what work has been done and what work still needs to be done. Moreover, a vast amount of education research on the teaching and learning of astronomy exists in dissertations that were never published and even more exists in the realm of un-disseminated grey literature hosted in conference proceedings and society newsletters going back decades. With a few notable exceptions far less extensive than the current project, there has been no comprehensive repository for cataloging astronomy education research methods and results to date. In response, an international cadre of scholars coordinated by the CAPER Center for Astronomy & Physics Education Research are creating the underlying structure for an online database in order to conduct an international Study of Astronomy Reasoning, iSTAR, project. The online iSTAR database serves as an online host to bring together in one place digital copies of hard to locate journal articles, isolated dissertations and theses, and professional meeting contributions to extend the world's scholars abilities to more easily find and utilize a far broader collection of astronomy education research literature than has been previously available. Works are categorized by research method, nature of study-participants, educational learning venue studied, country and language of the study, and other fruitfully useful categories. Scholars wishing to add their own literature resources are encouraged to contribute to the online database located at istardatabase.org

    2012-09-01

    Dual-use research of concern (DURC) is scientific research with significant potential for generating information that could be used to harm national security, the public health, or the environment. Editors responsible for journal policies and publication decisions play a vital role in ensuring that effective safeguards exist to cope with the risks of publishing scientific research with dual-use implications. We conducted an online survey of 127 chief editors of life science journals in 27 countries to examine their attitudes toward and experience with the review and publication of dual-use research of concern. Very few editors (11) had experience with biosecurity review, and no editor in our study reported having ever refused a submission on biosecurity grounds. Most respondents (74.8%) agreed that editors have a responsibility to consider biosecurity risks during the review process, but little consensus existed among editors on how to handle specific issues in the review and publication of research with potential dual-use implications. More work is needed to establish consensus on standards for the review and publication of dual-use research of concern in life science journals.

    2015-12-01

    Despite widespread recognition of a research-practice gap in multiple service sectors, less is known about how pre-existing communication channels facilitate the flow of information between researchers and practitioners. In the current study, we applied an existing typology of brokerage developed by Gould and Fernandez (Sociol Methodol 19:89-126, 1989) to examine what types of brokerage facilitate information spread between researchers and educational practitioners. Specifically, we conducted semi-structured interviews with 19 school administrators and staff in two public school districts regarding their experiences searching for information about instructional, health, and social skills programs. Using deductive content analysis, we found evidence of all five types of brokerage identified by Gould and Fernandez (1989). However, only three types of brokerage-gatekeepers, representatives, and liaisons-were involved in the flow of information between school administrators and researchers. Moreover, information transfer often occurred in longer chains that involved multiple, distinct types of brokerage. We conclude with the broad implications of our findings for narrowing the research-practice gap by improving researchers' dissemination efforts and practitioners' search for information.

    2016-01-01

    The ability to reproducibly identify clinically equivalent patient populations is critical to the vision of learning health care systems that implement and evaluate evidence-based treatments.

    Introduction: The ability to reproducibly identify clinically equivalent patient populations is critical to the vision of learning health care systems that implement and evaluate evidence-based treatments. The use of common or semantically equivalent phenotype definitions across research and health care use cases will support this aim. Currently, there is no single consolidated repository for computable phenotype definitions, making it difficult to find all definitions that already exist, and also hindering the sharing of definitions between user groups. Method: Drawing from our experience in an academic medical center that supports a number of multisite research projects and quality improvement studies, we articulate a framework that will support the sharing of phenotype definitions across research and health care use cases, and highlight gaps and areas that need attention and collaborative solutions. Framework: An infrastructure for re-using computable phenotype definitions and sharing experience across health care delivery and clinical research applications includes: access to a collection of existing phenotype definitions, information to evaluate their appropriateness for particular applications, a knowledge base of implementation guidance, supporting tools that are user-friendly and intuitive, and a willingness to use them. Next Steps: We encourage prospective researchers and health administrators to re-use existing EHR-based condition definitions where appropriate and share their results with others to support a national culture of learning health care. There are a number of federally funded resources to support these activities, and research sponsors should encourage their use. PMID:27563686

    Over the past two decades, researchers have increasingly used human biospecimens to evaluate hypotheses related to disease risk, outcomes and treatment. We conducted an analysis of population-science cancer research grants funded by the National Cancer Institute (NCI) to gain a more comprehensive understanding of biospecimens and common derivatives involved in those studies and identify opportunities for advancing the field. Data available for 1,018 extramural, peer-reviewed grants (active as of July 2012) supported by the Division of Cancer Control and Population Sciences (DCCPS), the NCI Division that supports cancer control and population-science extramural research grants, were analyzed. 455 of the grants were determined to involve biospecimens or derivatives. The most common specimen types included were whole blood (51% of grants), serum or plasma (40%), tissue (39%), and the biospecimen derivative, DNA (66%). While use of biospecimens in molecular epidemiology has become common, biospecimens for behavioral and social research is emerging, as observed in our analysis. Additionally, we found the majority of grants were using already existing biospecimens (63%). Grants that involved use of existing biospecimens resulted in lower costs (studies that used existing serum/plasma biospecimens were 4.2 times less expensive) and more publications per year (1.4 times) than grants collecting new biospecimens. This analysis serves as a first step at understanding the types of biospecimen collections supported by NCI DCCPS. There is room to encourage increased use of archived biospecimens and new collections of rarer specimen and cancer types, as well as for behavioral and social research. To facilitate these efforts, we are working to better catalogue our funded resources and make that data available to the extramural community.

  1. The professional clothing bank as evidence-based practice.

    PubMed

    Bishop, SueZanne Monique

    2015-01-01

    Little research exists linking interview-appropriate attire to improved employment outcomes for women. Thus, it appears that the professional clothing bank has not been investigated as evidence-based practice. To provide preliminary evidence for clothing banks, in this article the author synthesizes findings from existing research on the provision of a professional clothing bank as a means for offering interview-appropriate attire to poor women in job readiness programming. For context, job readiness programs are explored and a case study of one program operating a professional clothing bank is presented. Finally, preliminary considerations for planning and implementing clothing banks based on this literature review are given.

  2. The practice gap in the care of women following successful infertility treatments: unasked research questions in midwifery and nursing.

    PubMed

    Allan, Helen; Finnerty, Gina

    2007-06-01

    The aim of this paper is to highlight the gap between existing research evidence and nursing and midwifery practices in caring for women following successful in vitro fertilization (IVF) and gamete intrafallopian transfer (GIFT), and to suggest directions for research within these disciplines. We argue that although the number of couples in the UK experiencing fertility problems has risen, 1.4% of all births in the UK are as the result of infertility treatments (HFEA, 2005/2006); yet there is little research into the experiences of motherhood for women who successfully achieve pregnancy following IVF or GIFT. Consequently, there is negligible research evidence for nurses and midwives practicing in this area, and British healthcare staff appear to be unaware of the specific needs of infertile women during pregnancy, birth and early motherhood. In this paper we review the existing literature on this group of women, which falls into three areas: studies into the psychosocial development of the child conceived via IVF/GIFT/donor insemination; comparative studies into experiences of women following successful infertility treatment and women who conceive naturally; and studies into the experiences of women following successful IVF treatment. We review this literature to argue for research into the needs of infertile women following successful IVF/GIFT, to inform evidence for practice.

    2017-05-01

    Inquiry-based learning (IBL) is one of the teaching approaches that has been suggested by the Kementerian Pelajaran Malaysia (KPM). Although IBL has been in existence for many years, the effect of this approach in terms of teacher's verbal interaction during teaching has not been considered to any great extent. For this reason, a systematic review was conducted to observe the pattern of the existing IBL research. This systematic review of quantitative and qualitative studies published between 2006 and 2016 was undertaken by using the following databases: Taylor & Francis Online (2012-2015), Wiley Online Library (2012-2015), ScienceDirect, SpringerLink, SAGE Journals, and EBSCOHOST. Research articles from trustworthy websites were also used. The main keywords used were teacher verbal interaction, inquiry-based learning (IBL), secondary school science and classroom interaction. Eleven studies were included in this review but only two out of the eleven selected papers discussed teacher verbal interaction. Hence, more research needs to be conducted in order to observe the effect of IBL towards teacher's verbal interaction during learning sessions.

    2016-05-01

    Men's sexual overperception bias-where men tend to perceive greater sexual interest in women's behavior than actually exists-is a well-documented finding in previous research. All of the existing research, however, has tested this effect in the context of initial encounters or for fictitious or unknown targets. No research currently exists on how people perceive their romantic partner's sexual desire in the context of ongoing, intimate relationships. In 3 dyadic studies, we provide evidence that men in established romantic relationships err in the direction of the opposite bias and underperceive their romantic partner's sexual desire. We also demonstrate that this underperception bias is functional (particularly for men) in that it is associated with their partner feeling more satisfied and committed to the relationship. In addition, people are particularly likely to underperceive their partner's desire on days when they are motivated to avoid sexual rejection, and men's underperception bias is, in part, accounted for by men's higher general levels of sexual desire than women. The current studies extend previous findings on sexual perceptual biases and demonstrate the important role of context in men's judgments of a partner's sexual interest.

    PubMed

    Paige, Jane B; Morin, Karen H

    2016-01-01

    Q-sample construction is a critical step in Q-methodological studies. Prior to conducting Q-studies, researchers start with a population of opinion statements (concourse) on a particular topic of interest from which a sample is drawn. These sampled statements are known as the Q-sample. Although literature exists on methodological processes to conduct Q-methodological studies, limited guidance exists on the practical steps to reduce the population of statements to a Q-sample. A case exemplar illustrates the steps to construct a Q-sample in preparation for a study that explored perspectives nurse educators and nursing students hold about simulation design. Experts in simulation and Q-methodology evaluated the Q-sample for readability, clarity, and for representativeness of opinions contained within the concourse. The Q-sample was piloted and feedback resulted in statement refinement. Researchers especially those undertaking Q-method studies for the first time may benefit from the practical considerations to construct a Q-sample offered in this article. © The Author(s) 2014.

  15. Interventions aimed at increasing research use in nursing: a systematic review

    PubMed Central

    Thompson, David S; Estabrooks, Carole A; Scott-Findlay, Shannon; Moore, Katherine; Wallin, Lars

    2007-01-01

    Background There has been considerable interest recently in developing and evaluating interventions to increase research use by clinicians. However, most work has focused on medical practices; and nursing is not well represented in existing systematic reviews. The purpose of this article is to report findings from a systematic review of interventions aimed at increasing research use in nursing. Objective To assess the evidence on interventions aimed at increasing research use in nursing. Methods A systematic review of research use in nursing was conducted using databases (Medline, CINAHL, Healthstar, ERIC, Cochrane Central Register of Controlled Trials, and Psychinfo), grey literature, ancestry searching (Cochrane Database of Systematic Reviews), key informants, and manual searching of journals. Randomized controlled trials and controlled before- and after-studies were included if they included nurses, if the intervention was explicitly aimed at increasing research use or evidence-based practice, and if there was an explicit outcome to research use. Methodological quality was assessed using pre-existing tools. Data on interventions and outcomes were extracted and categorized using a pre-established taxonomy. Results Over 8,000 titles were screened. Three randomized controlled trials and one controlled before- and after-study met the inclusion criteria. The methodological quality of included studies was generally low. Three investigators evaluated single interventions. The most common intervention was education. Investigators measured research use using a combination of surveys (three studies) and compliance with guidelines (one study). Researcher-led educational meetings were ineffective in two studies. Educational meetings led by a local opinion leader (one study) and the formation of multidisciplinary committees (one study) were both effective at increasing research use. Conclusion Little is known about how to increase research use in nursing, and the evidence to support or refute specific interventions is inconclusive. To advance the field, we recommend that investigators: (1) use theoretically informed interventions to increase research use, (2) measure research use longitudinally using theoretically informed and psychometrically sound measures of research use, as well as, measuring patient outcomes relevant to the intervention, and (3) use more robust and methodologically sound study designs to evaluate interventions. If investigators aim to establish a link between using research and improved patient outcomes they must first identify those interventions that are effective at increasing research use.

    2006-11-01

    As a complementary medical system to Western medicine, traditional Chinese medicine (TCM) provides a unique theoretical and practical approach to the treatment of diseases over thousands of years. Confronted with the increasing popularity of TCM and the huge volume of TCM data, historically accumulated and recently obtained, there is an urgent need to explore these resources effectively by the techniques of knowledge discovery in database (KDD). This paper aims at providing an overview of recent KDD studies in TCM field. A literature search was conducted in both English and Chinese publications, and major studies of knowledge discovery in TCM (KDTCM) reported in these materials were identified. Based on an introduction to the state of the art of TCM data resources, a review of four subfields of KDTCM research was presented, including KDD for the research of Chinese medical formula, KDD for the research of Chinese herbal medicine, KDD for TCM syndrome research, and KDD for TCM clinical diagnosis. Furthermore, the current state and main problems in each subfield were summarized based on a discussion of existing studies, and future directions for each subfield were also proposed accordingly. A series of KDD methods are used in existing KDTCM researches, ranging from conventional frequent itemset mining to state of the art latent structure model. Considerable interesting discoveries are obtained by these methods, such as novel TCM paired drugs discovered by frequent itemset analysis, functional community of related genes discovered under syndrome perspective by text mining, the high proportion of toxic plants in the botanical family Ranunculaceae disclosed by statistical analysis, the association between M-cholinoceptor blocking drug and Solanaceae revealed by association rule mining, etc. It is particularly inspiring to see some studies connecting TCM with biomedicine, which provide a novel top-down view for functional genomics research. However, further developments of KDD methods are still expected to better adapt to the features of TCM. Existing studies demonstrate that KDTCM is effective in obtaining medical discoveries. However, much more work needs to be done in order to discover real diamonds from TCM domain. The usage and development of KDTCM in the future will substantially contribute to the TCM community, as well as modern life science.

  17. The effect of learning style on academic student success

    NASA Astrophysics Data System (ADS)

    Stackhouse, Omega N.

    The problem addressed in this study was that little was known about the impact on student academic achievement, when grouped by learning style, in a multiple intelligence based science curriculum. The larger problem was that many students were frequently unengaged and, consequently, low achieving in their science courses. This quantitative study used an ex post facto research design to better understand the impact of student learning style on the academic success of students in a Multiple Intelligence Theory based course room. Gardner's work on Multiple Intelligence served as the conceptual framework for this study. The research question for this study asked if academic instruction that employs multiple intelligence theories has a relationship with students' academic achievement differently according to their learning style group (auditory, visual, and kinesthetic). Existing data from 85 students were placed into 1 of 3 groups: (a) Auditory, (b) Visual, or (c) Kinesthetic Learning Style) using existing data from a student inventory instrument. The independent variable was existing data from student inventories of learning style and the dependent variable was existing student scores from the Physical Science End of Course Test. Existing data were taken from students that were all taught with the same strategies in similar classroom environments. The Physical Science End of Course Test was developed with stringent measures to protect validity by the developer, McGraw-Hill. Cronbach's Alpha was conducted to determine the internal reliability coefficient of the student inventory. The impact for social change is that adding to the body of knowledge regarding student learning style and science curriculum provides valuable information for teachers, administrators, and school policy makers. This will allow teachers to better prepare to engage their students' and to prepare them for their place in society.

    In this module, we have discussed study designs that have not been covered in the previous modules – ecologic studies and natural experiments. In an ecologic study, the unit of analysis is a group or aggregate rather than the individual. It may be the characteristics of districts, states, or countries. For example, per capita income across countries, income quintiles across districts, and proportion of college graduates in states. If the data already exist (such as global measures and prevalence of diseases, data sets such as the National Family Health Survey, census data), then ecologic studies are cheap and data are easy to collect. However, one needs to be aware of the “ecologic fallacy.” The researcher should not interpret ecologic level results at the individual level. In “natural experiments,” the researcher does not assign the exposure (as is the case in interventional studies) to the groups in the study. The exposure is assigned by a natural process. This may be due to existing policies or services (example, one city has laws against specific vehicles and the other city does not); changes in services or policies; or introduction of new laws (such helmet for bikers and seat-belts for cars). We would like to encourage researchers to explore the possibility of using these study designs to conduct studies. PMID:28216721

    In order to understand the current state of data sharing in observational research studies, we reviewed data sharing statements of observational studies published in a general medical journal, the British Medical Journal. We found that the majority (63%) of observational studies published between 2015 and 2017 included a statement that implied that data used in the study could not be shared. If the findings of our exploratory study are confirmed, room for improvement in the sharing of real-world or observational research data exists. PMID:29167735

  1. The Upper Rio Grande Basin as a Long-Term Hydrologic Observatory - Challenges and Opportunities

    NASA Astrophysics Data System (ADS)

    Springer, E.; Duffy, C.; Phillips, F.; Hogan, J.; Winter, C. L.

    2001-12-01

    Long-term hydrologic observatories (LTHO) have been identified as a key element to advance hydrologic science. Issues to be addressed are the size and locations of LTHOs to meet research needs and address water resources management concerns. To date, considerable small watershed research has been performed, and these have provided valuable insights into processes governing hydrologic response on local scales. For hydrology to advance as a science, more complete and coherent data sets at larger scales are needed to tie together local studies and examine lower frequency long wavelength processes that may govern the water cycle at the scale of river basins and continents. The objective of this poster is to describe the potential opportunities and challenges for the upper Rio Grande as a LTHO. The presence of existing research programs and facilities can be leveraged by a LTHO to develop the required scientific measurements. Within the upper Rio Grande Basin, there are two Long-Term Ecological Research sites, Jornada and Sevilleta; Los Alamos National Laboratory, which monitors the atmosphere, surface water and groundwater; a groundwater study is being performed by the USGS in the Albuquerque Basin to examine recharge and water quality issues. Additionally, the upper Rio Grande basin served as an USGS-NAWQA study site starting in the early 1990's and is currently being studied by SAHRA (NSF-STC) to understand sources of salinity of the river system; such studies provide an existing framework on which to base long-term monitoring of water quality. The upper Rio Grande Basin has a wealth of existing long-term climate, hydrologic and geochemical records on which to base an LTHO. Within the basin there are currently 122 discharge gages operated by the USGS; and many of these gages have long-term records of discharge. Other organizations operate additional surface water gages in the lower part of the basin. Long-term records of river chemistry have been kept by the USGS, U. S. Bureau of Reclamation, IBWC and EBID. Significantly, these records extend through periods of climate extremes, notably the 1950's drought. One challenge that the Rio Grande faces as a LTHO is combining datasets maintained by different agencies in order to address research questions at this spatial and temporal scale. Challenges facing the development of a LTHO on the Rio Grande include instrumentation over steep topographic and biological gradients that exist. Political issues surrounding any basin can create problems for making long-term measurements. Current water resources management requires a greater scientific understanding of coupled processes, serious improvements in predictive capability and available computational resources, both of which require a comprehensive hydrologic monitoring system beyond any which exist today.

    2003-12-01

    Conflicts of interest in research have long been seen to pose serious threats to the integrity of research. Indeed, the past two decades have revealed increased attention to the possible influence of conflicts of interest as the number of research studies funded by private industry have increased. We review empirical findings directly pertinent to issues concerning financial conflicts of interest in biomedical research, and we provide an overview of the current issues and state of understanding concerning such conflicts in research. We searched Medline from January 1992 to January 2002 to locate current studies that have reported primary or secondary empirical data pertaining to conflicts of interest in research. The rate of potential conflicts of interest for researchers appears to be at least 30% in some situations although the accuracy of such a rate is untested, and the rate of disclosure of conflicts of interest is as low as 2%. Furthermore, some evidence exists to indicate that researchers with conflicting interests may indeed offer different professional opinions and judgments than those for whom such conflicts do not exist. The effectiveness of various disclosure and management methods for conflicts of interest is unknown. We summarize the current empirical literature, concluding that relatively little is known based on such data. We suggest a number of questions that need to be answered by future research, and we offer recommendations for policy makers to consider and evaluate in the future in identifying, revealing, and managing conflicts of interest.

    With wind energy expanding rapidly in the U.S. and abroad, and with an increasing number of communities considering nearby wind power developments, there is a need to empirically investigate community concerns about wind project development. One such concern is that property values may be adversely affected by wind energy facilities, and relatively little existing research exists on the subject. The present research is based on almost 7,500 sales of single-family homes situated within ten miles of 24 existing wind facilities in nine different U.S. states. The conclusions of the study are drawn from four different hedonic pricing models. The modelmore » results are consistent in that neither the view of the wind facilities nor the distance of the home to those facilities is found to have a statistically significant effect on home sales prices.« less

    Duke, Dana; TKE Team

    2014-09-01

    A Frisch-gridded ionization chamber and the double energy (2E) analysis method were used to study mass yield distributions and average total kinetic energy (TKE) release from neutron-induced fission of 235U, 238U, and 239Pu. Despite decades of fission research, little or no TKE data exist for high incident neutron energies. Additional average TKE information at incident neutron energies relevant to defense- and energy-related applications will provide a valuable observable for benchmarking simulations. The data can also be used as inputs in theoretical fission models. The Los Alamos Neutron Science Center-Weapons Neutron Research (LANSCE - WNR) provides a neutron beam from thermal to hundreds of MeV, well-suited for filling in the gaps in existing data and exploring fission behavior in the fast neutron region. The results of the studies on 238U, 235U, and 239Pu will be presented. LA-UR-14-24921.

    As more Spanish speaking immigrants participate in and become the focus of research studies, questions arise about the appropriateness of existing research tools. Questionnaires have often been adapted from English language instruments and tested among college- educated Hispanic-Americans. Little has been written regarding the testing and evaluation of research tools among less educated Latino immigrants. The purpose of this study was to revise and evaluate the appropriateness of a battery of existing Spanish-language questionnaires for a physical activity intervention for immigrant Hispanic women. A three-step process was utilized to evaluate, adapt and test Spanish versions of the Self-Efficacy and Exercise Habits Survey, an abbreviated version of the Hispanic Stress Inventory-Immigrant version and the Latina Values Scale. The revised tools demonstrated acceptable validity and reliability. The adaptations improved the readability of the tools, resulting in a greater response rate, less missing data and fewer extreme responses. Psychometric limitations to the adaptation of Likert scales are discussed. PMID:22030592

    An intrusion detection system (IDS) is hardware, software or a combination of two, for monitoring network or system activities to detect malicious signs. In computer security, designing a robust intrusion detection system is one of the most fundamental and important problems. The primary function of system is detecting intrusion and gives alerts when user tries to intrusion on timely manner. In these techniques when IDS find out intrusion it will send alert massage to the system administrator. Anomaly detection is an important problem that has been researched within diverse research areas and application domains. This survey tries to provide a structured and comprehensive overview of the research on anomaly detection. From the existing anomaly detection techniques, each technique has relative strengths and weaknesses. The current state of the experiment practice in the field of anomaly-based intrusion detection is reviewed and survey recent studies in this. This survey provides a study of existing anomaly detection techniques, and how the techniques used in one area can be applied in another application domain.

    An exploratory study was conducted that investigated the influence of technical uncertainty and project complexity on information use by U.S. industry-affiliated aerospace engineers and scientists. The study utilized survey research in the form of a self-administered mail questionnaire. U.S. aerospace engineers and scientists on the Society of Automotive Engineers (SAE) mailing list served as the study population. The adjusted response rate was 67 percent. The survey instrument is appendix C to this report. Statistically significant relationships were found to exist between technical uncertainty, project complexity, and information use. Statistically significant relationships were found to exist between technical uncertainty, project complexity, and the use of federally funded aerospace R&D. The results of this investigation are relevant to researchers investigating information-seeking behavior of aerospace engineers. They are also relevant to R&D managers and policy planners concerned with transferring the results of federally funded aerospace R&D to the U.S. aerospace industry.

  11. Comorbid forms of psychopathology: key patterns and future research directions.

    Cerdá, Magdalena; Sagdeo, Aditi; Galea, Sandro

    2008-01-01

    The purpose of this review is to systematically appraise the peer-reviewed literature about clustered forms of psychopathology and to present a framework that can be useful for studying comorbid psychiatric disorders. The review focuses on four of the most prevalent types of mental health problems: anxiety, depression, conduct disorder, and substance abuse. The authors summarize existing empirical research on the distribution of concurrent and sequential comorbidity in children and adolescents and in adults, and they review existing knowledge about exogenous risk factors that influence comorbidity. The authors include articles that used a longitudinal study design and used psychiatric definitions of the disorders. A total of 58 articles met the inclusion criteria and were assessed. Current evidence demonstrates a reciprocal, sequential relation between most comorbid pairs, although the mechanisms that mediate such links remain to be explained. Methodological concerns include the inconsistency of measurement of the disorders across studies, small sample sizes, and restricted follow-up times. Given the significant mental health burden placed by comorbid disorders, and their high prevalence across populations, research on the key risk factors for clustering of psychopathology is needed.

  12. Establishing the credibility of qualitative research findings: the plot thickens.

    1999-08-01

    Qualitative research is increasingly recognized and valued and its unique place in nursing research is highlighted by many. Despite this, some nurse researchers continue to raise epistemological issues about the problems of objectivity and the validity of qualitative research findings. This paper explores the issues relating to the representativeness or credibility of qualitative research findings. It therefore critiques the existing distinct philosophical and methodological positions concerning the trustworthiness of qualitative research findings, which are described as follows: quantitative studies should be judged using the same criteria and terminology as quantitative studies; it is impossible, in a meaningful way, for any criteria to be used to judge qualitative studies; qualitative studies should be judged using criteria that are developed for and fit the qualitative paradigm; and the credibility of qualitative research findings could be established by testing out the emerging theory by means of conducting a deductive quantitative study. The authors conclude by providing some guidelines for establishing the credibility of qualitative research findings.

    2010-10-01

    There exists currently a fair degree of introspection in the pain research community about the value of animal research. This review represents a defense of animal research in pain. We discuss the inherent advantage of animal models over human research as well as the crucial complementary roles animal studies play vis-à-vis human imaging and genetic studies. Finally, we discuss recent developments in animal models of pain that should improve the relevance and translatability of findings using laboratory animals. We believe that pain research using animal models is a continuing necessity-to understand fundamental mechanisms, identify new analgesic targets, and inform, guide and follow up human studies-if novel analgesics are to be developed for the treatment of chronic pain.

    There are a number of significant challenges encountered when studying development over an extended period of time including subject attrition, changing measurement structures across group and developmental period, and the need to invest substantial time and money. Integrative data analysis is an emerging set of methodologies that overcomes many of the challenges of single sample designs through the pooling of data drawn from multiple existing developmental studies. This approach is characterized by a host of advantages, but this also introduces several new complexities that must be addressed prior to broad adoption by developmental researchers. In this paper we focus on methods for fitting measurement models and creating scale scores using data drawn from multiple longitudinal studies. We present findings from the analysis of repeated measures of internalizing symptomatology that were pooled from three existing developmental studies. We describe and demonstrate each step in the analysis and we conclude with a discussion of potential limitations and directions for future research. PMID:18331129

    2010-01-01

    US transportation systems have been identified as a problem for public health, as they often encourage automobile transportation and discourage physical activity. This paper provides a case study examination of the Public Health Component of the Wasatch Front Regional Council's Regional Transportation Plan. This plan provides an example of what transportation planners at Utah's largest metropolitan planning organization (MPO) are doing to encourage physical activity through transportation. Existing active living research was used to guide recommendations using a process that included a comprehensive literature review and a review of existing state programs, advisory group and stakeholder meetings, and policy recommendations based on existing local conditions. Stakeholders from a diversity of background and interests came together with one common goal: to improve public health. Based on this collaborative process, nine policy approaches were specifically recommended for approval and integration in the Wasatch Front Regional Transportation Plan. By using current research as a guide and integrating a variety of interests, the Wasatch Front Regional Council is setting a new standard for a collaborative multi-modal focus in transportation planning, which can be replicated nationwide.

    2018-01-01

    Background Increasing evidence shows that health inequalities exist between and within countries, and emphasis has been placed on strengthening the production and use of the global health inequalities research, so as to improve capacities to act. Yet, a comprehensive overview of this evidence base is still needed, to determine what is known about the global and historical scientific production on health inequalities to date, how is it distributed in terms of country income groups and world regions, how has it changed over time, and what international collaboration dynamics exist. Methods A comprehensive bibliometric analysis of the global scientific production on health inequalities, from 1966 to 2015, was conducted using Scopus database. The historical and global evolution of the study of health inequalities was considered, and through joinpoint regression analysis and visualisation network maps, the preceding questions were examined. Findings 159 countries (via authorship affiliation) contributed to this scientific production, three times as many countries than previously found. Scientific output on health inequalities has exponentially grown over the last five decades, with several marked shift points, and a visible country-income group affiliation gradient in the initiation and consistent publication frequency. Higher income countries, especially Anglo-Saxon and European countries, disproportionately dominate first and co-authorship, and are at the core of the global collaborative research networks, with the Global South on the periphery. However, several country anomalies exist that suggest that the causes of these research inequalities, and potential underlying dependencies, run deeper than simply differences in country income and language. Conclusions Whilst the global evidence base has expanded, Global North-South research gaps exist, persist and, in some cases, are widening. Greater understanding of the structural determinants of these research inequalities and national research capacities is needed, to further strengthen the evidence base, and support the long term agenda for global health equity.

    Carolan, Clare M; Forbat, Liz; Smith, Annetta

    2016-04-01

    Case study is a long-established research tradition which predates the recent surge in mixed-methods research. Although a myriad of nuanced definitions of case study exist, seminal case study authors agree that the use of multiple data sources typify this research approach. The expansive case study literature demonstrates a lack of clarity and guidance in designing and reporting this approach to research. Informed by two reviews of the current health care literature, we posit that methodological description in case studies principally focuses on description of case study typology, which impedes the construction of methodologically clear and rigorous case studies. We draw from the case study and mixed-methods literature to develop the DESCARTE model as an innovative approach to the design, conduct, and reporting of case studies in health care. We examine how case study fits within the overall enterprise of qualitatively driven mixed-methods research, and the potential strengths of the model are considered. © The Author(s) 2015.

  18. Neuroscience-related research in Ghana: a systematic evaluation of direction and capacity.

    Quansah, Emmanuel; Karikari, Thomas K

    2016-02-01

    Neurological and neuropsychiatric diseases account for considerable healthcare, economic and social burdens in Ghana. In order to effectively address these burdens, appropriately-trained scientists who conduct high-impact neuroscience research will be needed. Additionally, research directions should be aligned with national research priorities. However, to provide information about current neuroscience research productivity and direction, the existing capacity and focus need to be identified. This would allow opportunities for collaborative research and training to be properly explored and developmental interventions to be better targeted. In this study, we sought to evaluate the existing capacity and direction of neuroscience-related research in Ghana. To do this, we examined publications reporting research investigations authored by scientists affiliated with Ghanaian institutions in specific areas of neuroscience over the last two decades (1995-2015). 127 articles that met our inclusion criteria were systematically evaluated in terms of research foci, annual publication trends and author affiliations. The most actively-researched areas identified include neurocognitive impairments in non-nervous system disorders, depression and suicide, epilepsy and seizures, neurological impact of substance misuse, and neurological disorders. These studies were mostly hospital and community-based surveys. About 60% of these articles were published in the last seven years, suggesting a recent increase in research productivity. However, data on experimental and clinical research outcomes were particularly lacking. We suggest that future investigations should focus on the following specific areas where information was lacking: large-scale disease epidemiology, effectiveness of diagnostic platforms and therapeutic treatments, and the genetic, genomic and molecular bases of diseases.

    2017-08-01

    Increasingly, researchers need to demonstrate the impact of their research to their sponsors, funders, and fellow academics. However, the most appropriate way of measuring the impact of healthcare research is subject to debate. We aimed to identify the existing methodological frameworks used to measure healthcare research impact and to summarise the common themes and metrics in an impact matrix. Two independent investigators systematically searched the Medical Literature Analysis and Retrieval System Online (MEDLINE), the Excerpta Medica Database (EMBASE), the Cumulative Index to Nursing and Allied Health Literature (CINAHL+), the Health Management Information Consortium, and the Journal of Research Evaluation from inception until May 2017 for publications that presented a methodological framework for research impact. We then summarised the common concepts and themes across methodological frameworks and identified the metrics used to evaluate differing forms of impact. Twenty-four unique methodological frameworks were identified, addressing 5 broad categories of impact: (1) 'primary research-related impact', (2) 'influence on policy making', (3) 'health and health systems impact', (4) 'health-related and societal impact', and (5) 'broader economic impact'. These categories were subdivided into 16 common impact subgroups. Authors of the included publications proposed 80 different metrics aimed at measuring impact in these areas. The main limitation of the study was the potential exclusion of relevant articles, as a consequence of the poor indexing of the databases searched. The measurement of research impact is an essential exercise to help direct the allocation of limited research resources, to maximise research benefit, and to help minimise research waste. This review provides a collective summary of existing methodological frameworks for research impact, which funders may use to inform the measurement of research impact and researchers may use to inform study design decisions aimed at maximising the short-, medium-, and long-term impact of their research.

    Advances in “omics”-based fields have produced an explosion of new information, fueling high expectations for improved public and individualized health. Unfortunately, there exists a widening gap between basic biochemistry and “omics”-based population research, with both disciplines failing to translate their full potential impact to human health applications. A paucity of comprehensive study systems is one of the many roadblocks faced by translational research today. This commentary will highlight the current status of such research, particularly emphasizing the role of nutrigenomics. PMID:25364700

    Frameworks or problem solving environments that support application development form an active area of research. The Multidisciplinary Optimization Branch at NASA Langley Research Center is investigating frameworks for supporting multidisciplinary analysis and optimization research. The Branch has generated a list of framework requirements, based on the experience gained from the Framework for Interdisciplinary Design Optimization project and the information acquired during a framework evaluation process. In this study, four existing frameworks are examined against these requirements. The results of this examination suggest several topics for further framework research.

    2014-09-01

    Standards for reporting exist for many types of quantitative research, but currently none exist for the broad spectrum of qualitative research. The purpose of the present study was to formulate and define standards for reporting qualitative research while preserving the requisite flexibility to accommodate various paradigms, approaches, and methods. The authors identified guidelines, reporting standards, and critical appraisal criteria for qualitative research by searching PubMed, Web of Science, and Google through July 2013; reviewing the reference lists of retrieved sources; and contacting experts. Specifically, two authors reviewed a sample of sources to generate an initial set of items that were potentially important in reporting qualitative research. Through an iterative process of reviewing sources, modifying the set of items, and coding all sources for items, the authors prepared a near-final list of items and descriptions and sent this list to five external reviewers for feedback. The final items and descriptions included in the reporting standards reflect this feedback. The Standards for Reporting Qualitative Research (SRQR) consists of 21 items. The authors define and explain key elements of each item and provide examples from recently published articles to illustrate ways in which the standards can be met. The SRQR aims to improve the transparency of all aspects of qualitative research by providing clear standards for reporting qualitative research. These standards will assist authors during manuscript preparation, editors and reviewers in evaluating a manuscript for potential publication, and readers when critically appraising, applying, and synthesizing study findings.

    2014-07-01

    To identify unmet research needs of state and community tobacco control practitioners pertaining to electronic nicotine delivery systems (ENDS or e-cigarettes) that would inform policy and practice efforts at the state and community levels, and to describe ENDS-related research and dissemination activities of the National Cancer Institute-funded State and Community Tobacco Control Research Initiative. To determine specific research gaps relevant to state and community tobacco control practice, we analysed survey data collected from tobacco control programmes (TCPs) in all 50 U.S. states and the District of Columbia (N=51). Survey items covered a range of ENDS issues: direct harm to users, harm of secondhand vapour, cessation, flavours, constituents and youth access. There is no ENDS topic on which a majority of state TCP managers feel very informed. They feel least informed about harms of secondhand vapour while also reporting that this information is among the most important for their programme. A majority (N=31) of respondents indicated needs for research on the implications of ENDS products for existing policies. TCP managers report that ENDS research is highly important for practice and need research-based information to inform decision making around the inclusion of ENDS in existing tobacco control policies. For optimal relevance to state and community TCPs, research on ENDS should prioritise study of the health effects of ENDS use and secondhand exposure to ENDS vapour in the context of existing tobacco control policies.

  16. Comparative effectiveness research in cancer with observational data.

    PubMed

    Giordano, Sharon H

    2015-01-01

    Observational studies are increasingly being used for comparative effectiveness research. These studies can have the greatest impact when randomized trials are not feasible or when randomized studies have not included the population or outcomes of interest. However, careful attention must be paid to study design to minimize the likelihood of selection biases. Analytic techniques, such as multivariable regression modeling, propensity score analysis, and instrumental variable analysis, also can also be used to help address confounding. Oncology has many existing large and clinically rich observational databases that can be used for comparative effectiveness research. With careful study design, observational studies can produce valid results to assess the benefits and harms of a treatment or intervention in representative real-world populations.

    2017-01-01

    Despite the crucial role of mentoring, little literature exists that addresses distance mentoring among health researchers. This article provides three case studies showcasing protégés at different stages of career development (one in graduate school, one as an early-stage researcher, and one as an established researcher). Each case study provides a brief history of the relationship, examines the benefits and challenges of working together at a distance, and discusses the lessons learned from both the mentor and the protégé over the course of these relationships. A mentoring model, examples of mentoring communications, and potential promising practices are also provided and discussed.

    2009-01-01

    The rising burden of cancer in the developing world calls for a re-evaluation of the treatment strategies employed to improve patient management, early detection and understanding of the disease. There is thus an increasing demand for interdisciplinary research that integrates two or more disciplines of what may seemed to be highly unrelated and yet very much needed as strategies for success in research. This paper presents the processes and barriers faced in building partnerships in oral cancer research in a developing country. A case study was undertaken in a developing country (Malaysia) to assess the strengths and weaknesses of the situation leading to the formation of a multidisciplinary research partnership in oral cancer. Following the formalization of the partnership, further evaluation was undertaken to identify measures that can assist in sustaining the partnership. The group identifies its strength as the existence of academia, research-intensive NGOs and good networking of clinicians via the existence of the government's network of healthcare provider system who are the policy makers. The major weaknesses identified are the competing interest between academia and NGOs to justify their existence due to the lack of funding sources and well trained human resources. With the growing partnership, the collaborative group recognizes the need to develop standard operating procedures (SOPs) and guidelines for the sharing and usage of resources in order to safeguard the interest of the original partners while also attending to the needs of the new partners.

  3. Using the CABLES model to assess and minimize risk in research: control group hazards.

    PubMed

    Koocher, G P

    2002-01-01

    CABLES is both an acronym and metaphor for conceptualizing research participation risk by considering 6 distinct domains in which risks of harm to research participants may exist: cognitive, affective, biological, legal, economic, and social/cultural. These domains are described and illustrated, along with suggestions for minimizing or eliminating the potential hazards to human participants in biomedical and behavioral science research. Adoption of a thoughtful ethical analysis addressing all 6 CABLES strands in designing research provides a strong protective step toward safeguarding and promoting the well-being of study participants.

    2016-09-01

    Purpose Misinformation and negative attitudes toward disability contribute to lower employment rates among people with disabilities. Diversity training is an intervention intended to improve intergroup relations and reduce prejudice. We conducted a systematic review to determine the use and effectiveness of disability diversity training aimed at improving employment outcomes for employees with disabilities. Methods Five databases were searched for peer-reviewed studies of disability diversity training interventions provided within the workplace. Studies identified for inclusion were assessed for quality of methodology. Results Of the total of 1322 articles identified by the search, three studies met the criteria for inclusion. Two of the three articles focused specifically on training to improve outcomes related to workplace injuries among existing employees. The other study provided an initial test of a more general disability diversity training program. Conclusions There is currently a lack of empirically validated diversity training programs that focus specifically on disability. A number of disability diversity trainings and resources exist, but none have been well researched. Related literature on diversity training and disability awareness suggests the possibility for enhancing diversity training practices through training design, content, participant, and outcomes considerations. By integrating best practices in workplace diversity training with existing disability training resources, practitioners and researchers may be able to design effective disability diversity training programs.

    Developing high-quality scientific research will be most effective if research communities with diverse skills and interests are able to share information and knowledge, are aware of the major challenges across disciplines, and can exploit economies of scale to provide robust answers and better inform policy. We evaluate opportunities and challenges facing the development of a more interactive research environment by developing an interdisciplinary synthesis of research on a single geographic region. We focus on the Amazon as it is of enormous regional and global environmental importance and faces a highly uncertain future. To take stock of existing knowledge and provide a framework for analysis we present a set of mini-reviews from fourteen different areas of research, encompassing taxonomy, biodiversity, biogeography, vegetation dynamics, landscape ecology, earth-atmosphere interactions, ecosystem processes, fire, deforestation dynamics, hydrology, hunting, conservation planning, livelihoods, and payments for ecosystem services. Each review highlights the current state of knowledge and identifies research priorities, including major challenges and opportunities. We show that while substantial progress is being made across many areas of scientific research, our understanding of specific issues is often dependent on knowledge from other disciplines. Accelerating the acquisition of reliable and contextualized knowledge about the fate of complex pristine and modified ecosystems is partly dependent on our ability to exploit economies of scale in shared resources and technical expertise, recognise and make explicit interconnections and feedbacks among sub-disciplines, increase the temporal and spatial scale of existing studies, and improve the dissemination of scientific findings to policy makers and society at large. Enhancing interaction among research efforts is vital if we are to make the most of limited funds and overcome the challenges posed by addressing large-scale interdisciplinary questions. Bringing together a diverse scientific community with a single geographic focus can help increase awareness of research questions both within and among disciplines, and reveal the opportunities that may exist for advancing acquisition of reliable knowledge. This approach could be useful for a variety of globally important scientific questions. © 2010 The Authors. Biological Reviews © 2010 Cambridge Philosophical Society.

    Handels, Ron L H; Wolfs, Claire A G; Aalten, Pauline; Joore, Manuela A; Verhey, Frans R J; Severens, Johan L

    2014-03-01

    The objective of this study is to systematically review the literature on economic evaluations of interventions for the early diagnosis of Alzheimer's disease (AD) and related disorders and to describe their general and methodological characteristics. We focused on the diagnostic aspects of the decision models to assess the applicability of existing decision models for the evaluation of the recently revised diagnostic research criteria for AD. PubMed and the National Institute for Health Research Economic Evaluation database were searched for English-language publications related to economic evaluations on diagnostic technologies. Trial-based economic evaluations were assessed using the Consensus on Health Economic Criteria list. Modeling studies were assessed using the framework for quality assessment of decision-analytic models. The search retrieved 2109 items, from which eight decision-analytic modeling studies and one trial-based economic evaluation met all eligibility criteria. Diversity among the study objective and characteristics was considerable and, despite considerable methodological quality, several flaws were indicated. Recommendations were focused on diagnostic aspects and the applicability of existing models for the evaluation of recently revised diagnostic research criteria for AD.

    Dismukes, R. Key

    2010-01-01

    In this review, oriented to the human factors community, I will summarize and provide a perspective on recent research and theory on prospective memory. This will not be an exhaustive review of literature, which is already available in two excellent recent books that provide a wealth of detail on the current state of experimental research (Kliegel, McCaniel, & Einstein, 2008; McDaniel & Einstein, 2007; also see Brandimonte, Einstein, & McDaniel, 1996, for a still relevant overview of the field as it was emerging). Rather, I will explore the limits of existing experimental paradigms and theory, Vvilich, in my opinion, fail to capture some critical aspects of performance outside the laboratory. I will also review the relatively few studies in workplace and everyday settings and will discuss several studies that attempt to bridge between the bulk of experimental studies and these few naturalistic studies. Finally, I will describe countermeasures that can reduce vulnerability to forgetting to perform intended tasks, and I will propose a research agenda that would extend existing experimental and theoretical approaches and would support human factors practitioners by generating information on a wide range of issues relevant to prospective memory performance in natural settings.

  11. Human resource information systems in health care: a systematic evidence review

    PubMed Central

    Tursunbayeva, Aizhan; Bunduchi, Raluca; Franco, Massimo

    2017-01-01

    Objective: This systematic review aimed to: (1) determine the prevalence and scope of existing research on human resource information systems (HRIS) in health organizations; (2) analyze, classify, and synthesize evidence on the processes and impacts of HRIS development, implementation, and adoption; and (3) generate recommendations for HRIS research, practice, and policy, with reference to the needs of different stakeholders. Methods: A structured search strategy was used to interrogate 10 electronic databases indexing research from the health, social, management, technology, and interdisciplinary sciences, alongside gray literature sources and reference lists of qualifying studies. There were no restrictions on language or publication year. Two reviewers screened publications, extracted data, and coded findings according to the innovation stages covered in the studies. The Critical Appraisal Skills Program checklist was adopted to assess study quality. The process of study selection was charted using a Preferred Items for Systematic Reviews and Meta-Analysis (PRISMA) diagram. Results: Of the 6824 publications identified by the search strategy, 68, covering 42 studies, were included for final analysis. Research on HRIS in health was interdisciplinary, often atheoretical, conducted primarily in the hospital sector of high-income economies, and largely focused uncritically on use and realized benefits. Discussion and Conclusions: While studies of HRIS in health exist, the overall lack of evaluative research raises unanswered questions about their capacity to improve quality and efficiency and enable learning health systems, as well as how sociotechnical complexity influences implementation and effectiveness. We offer this analysis to decision makers and managers considering or currently implementing an HRIS, and make recommendations for further research.

    Hameed, Abdul; Khoshkbarforoushha, Alireza; Ranjan, Rajiv

    In a cloud computing paradigm, energy efficient allocation of different virtualized ICT resources (servers, storage disks, and networks, and the like) is a complex problem due to the presence of heterogeneous application (e.g., content delivery networks, MapReduce, web applications, and the like) workloads having contentious allocation requirements in terms of ICT resource capacities (e.g., network bandwidth, processing speed, response time, etc.). Several recent papers have tried to address the issue of improving energy efficiency in allocating cloud resources to applications with varying degree of success. However, to the best of our knowledge there is no published literature on this subjectmore » that clearly articulates the research problem and provides research taxonomy for succinct classification of existing techniques. Hence, the main aim of this paper is to identify open challenges associated with energy efficient resource allocation. In this regard, the study, first, outlines the problem and existing hardware and software-based techniques available for this purpose. Furthermore, available techniques already presented in the literature are summarized based on the energy-efficient research dimension taxonomy. The advantages and disadvantages of the existing techniques are comprehensively analyzed against the proposed research dimension taxonomy namely: resource adaption policy, objective function, allocation method, allocation operation, and interoperability.« less

  18. Critical Speed of The Glass Glue Machine's Creep and Influence Factors Analysis

    NASA Astrophysics Data System (ADS)

    Yang, Jianxi; Huang, Jian; Wang, Liying; Shi, Jintai

    When automatic glass glue machine works, two questions of the machine starting vibrating and stick-slip motion are existing. These problems should be solved. According to these questions, a glue machine's model for studying stick-slip is established. Based on the dynamics system describing of the model, mathematical expression is presented. The creep critical speed expression is constructed referring to existing research achievement and a new conclusion is found. The influencing factors of stiffness, dampness, mass, velocity, difference of static and kinetic coefficient of friction are analyzed through Matlab simulation. Research shows that reasonable choice of influence parameters can improve the creep phenomenon. These all supply the theory evidence for improving the machine's motion stability.

  19. Heteroscedastic Latent Trait Models for Dichotomous Data.

    PubMed

    Molenaar, Dylan

    2015-09-01

    Effort has been devoted to account for heteroscedasticity with respect to observed or latent moderator variables in item or test scores. For instance, in the multi-group generalized linear latent trait model, it could be tested whether the observed (polychoric) covariance matrix differs across the levels of an observed moderator variable. In the case that heteroscedasticity arises across the latent trait itself, existing models commonly distinguish between heteroscedastic residuals and a skewed trait distribution. These models have valuable applications in intelligence, personality and psychopathology research. However, existing approaches are only limited to continuous and polytomous data, while dichotomous data are common in intelligence and psychopathology research. Therefore, in present paper, a heteroscedastic latent trait model is presented for dichotomous data. The model is studied in a simulation study, and applied to data pertaining alcohol use and cognitive ability.

    2013-08-01

    The aim of this study was to quantify the agreement among individual National Dental Practice-Based Research Network dentists' self-reported treatment decisions for primary occlusal caries, primary proximal caries, and existing restorations. Five hypothetical clinical scenarios were presented: primary occlusal caries; primary proximal caries; and whether three existing restorations should be repaired or replaced. We quantified the probability that dentists who recommended later restorative intervention for primary caries were the same ones who recommended that existing restorations be repaired instead of replaced. Dentists who recommended later restorative treatment of primary occlusal caries and proximal caries at a more-advanced stage were significantly more likely to recommend repair instead of replacement. Agreement among dentists on a threshold stage for the treatment of primary caries ranged from 40 to 68%, while that for repair or replacement of existing restorations was 36 to 43%. Dentists who recommended repair rather than replacement of existing restorations were significantly more likely to recommend later treatment of primary caries. Conversely, dentists who recommended treatment of primary caries at an earlier stage were significantly more likely to recommend replacement of the entire restoration. Between-dentist agreement for primary caries treatment was better than between-dentist agreement for repair or replacement of existing restorations. These findings suggest consistency in how individual dentists approach the treatment of primary caries and existing restorations. However, substantial variation was found between dentists in their treatment decisions about the same teeth. Copyright © 2013 Elsevier Ltd. All rights reserved.

  3. Is smartphone addiction really an addiction?

    2018-06-13

    Aims In light of the rise in research on technological addictions and smartphone addiction in particular, the aim of this paper was to review the relevant literature on the topic of smartphone addiction and determine whether this disorder exists or if it does not adequately satisfy the criteria for addiction. Methods We reviewed quantitative and qualitative studies on smartphone addiction and analyzed their methods and conclusions to make a determination on the suitability of the diagnosis "addiction" to excessive and problematic smartphone use. Results Although the majority of research in the field declares that smartphones are addictive or takes the existence of smartphone addiction as granted, we did not find sufficient support from the addiction perspective to confirm the existence of smartphone addiction at this time. The behaviors observed in the research could be better labeled as problematic or maladaptive smartphone use and their consequences do not meet the severity levels of those caused by addiction. Discussion and conclusions Addiction is a disorder with severe effects on physical and psychological health. A behavior may have a similar presentation as addiction in terms of excessive use, impulse control problems, and negative consequences, but that does not mean that it should be considered an addiction. We propose moving away from the addiction framework when studying technological behaviors and using other terms such as "problematic use" to describe them. We recommend that problematic technology use is to be studied in its sociocultural context with an increased focus on its compensatory functions, motivations, and gratifications.

  4. The relationship of weekend admission and mortality on the public medical wards at a Kenyan referral hospital.

    2015-11-01

    Research has demonstrated disparities in the outcomes of patients admitted to hospital on weekends in high-income countries. No published research has evaluated if any similar discrepancy exists in low-resource settings. To determine if any difference in mortality exists between weekend and weekday admissions on the public medical wards at a Kenyan referral hospital, we performed a retrospective observational study of inpatients over a 3-month study period. During the study period, 261 (27.3%) of the 956 patients were admitted over the weekend. The mortality rates for patients admitted on weekends and weekdays did not differ with 156 (22.4%) of the 695 patients admitted on weekdays dying compared to 55 (21.1%) of the 261 patients admitted on weekends. After adjusting for age, insurance status, co-morbid illness, HIV status, employment, referral status and gender, still no association existed between weekend admission and mortality. Among adult patients on the medical wards, patients admitted on weekends had similar mortality rates to those admitted on weekdays. This similarity may reflect a stable level of care or a generalized shortage of resources and staffing that subsumes any impact of weekly variations. Future research examining optimal staffing and resource levels is needed in such settings. © The Author 2015.

  5. Strengthening population health interventions: developing the CollaboraKTion Framework for Community-Based Knowledge Translation.

    PubMed

    Jenkins, Emily K; Kothari, Anita; Bungay, Vicky; Johnson, Joy L; Oliffe, John L

    2016-08-30

    Much of the research and theorising in the knowledge translation (KT) field has focused on clinical settings, providing little guidance to those working in community settings. In this study, we build on previous research in community-based KT by detailing the theory driven and empirically-informed CollaboraKTion framework. A case study design and ethnographic methods were utilised to gain an in-depth understanding of the processes for conducting a community-based KT study as a means to distilling the CollaboraKTion framework. Drawing on extensive field notes describing fieldwork observations and interactions as well as evidence from the participatory research and KT literature, we detail the processes and steps undertaken in this community-based KT study as well as their rationale and the challenges encountered. In an effort to build upon existing knowledge, Kitson and colleagues' co-KT framework, which provides guidance for conducting KT aimed at addressing population-level health, was applied as a coding structure to inform the current analysis. This approach was selected because it (1) supported the application of an existing community-based KT framework to empirical data and (2) provided an opportunity to contribute to the theory and practice gaps in the community-based KT literature through an inductively derived empirical example. Analysis revealed that community-based KT is an iterative process that can be viewed as comprising five overarching processes: (1) contacting and connecting; (2) deepening understandings; (3) adapting and applying the knowledge base; (4) supporting and evaluating continued action; and (5) transitioning and embedding as well as several key elements within each of these processes (e.g. building on existing knowledge, establishing partnerships). These empirically informed theory advancements in KT and participatory research traditions are summarised in the CollaboraKTion framework. We suggest that community-based KT researchers place less emphasis on enhancing uptake of specific interventions and focus on collaboratively identifying and creating changes to the contextual factors that influence health outcomes. The CollaboraKTion framework can be used to guide the development, implementation and evaluation of contextually relevant, evidence-informed initiatives aimed at improving population health, amid providing a foundation to leverage future research and practice in this emergent KT area.

  6. Disparate compensation policies for research related injury in an era of multinational trials: a case study of Brazil, Russia, India, China and South Africa.

    Compensation for research related injuries is a subject that is increasingly gaining traction in developing countries which are burgeoning destinations of multi center research. However, the existence of disparate compensation rules violates the ethical principle of fairness. The current paper presents a comparison of the policies of Brazil, Russia, India, China and South Africa (BRICS). A systematic search of good clinical practice guidelines was conducted employing search strategies modeled in line with the recommendations of ADPTE Collaboration (2007). The search focused on three main areas namely bibliographic data bases, clinical practice guidelines data bases and a restricted internet search. A manual search of references cited in relevant guideline documents was also conducted. The search terms, Medical Subject Headings (MeSH) and key words were developed for a PubMed platform and then adapted for all other data bases. The search terms were kept constant for each country with the only difference being the country name. The documents so obtained were subjected to systematic content analysis. The study revealed that there is vast panoply of regulations which exist on a continuum. On one extreme is India with comprehensive regulations that are codified into law, and on the other end there is China which does not have specific laws regulating research related injuries. There are a number of differences and similarities such as mandatory insurance requirements, existence of no fault compensation, compensable injuries and the role of research ethics committees. It is imperative to enact legislations that protect participants without stifling the research enterprise. There is need for consistency and ideally harmonization of such regulations at a global level. A model policy on compensation for research related injuries should borrow from the best aspects of the different country policies and should be informed by the cardinal ethics principles of autonomy, justice and beneficence.

    Dual language exposure and bilingualism are relatively common experiences for children. The present review set out to synthesize the existing research on cognitive development in bilingual children and to identify the gaps and the methodological concerns present in the existing research. A search of major data bases for research conducted with typically-developing, preschool-age dual language learners between 2000-2013 yielded 102 peer-reviewed articles. The existing evidence points to areas of cognitive development in bilingual children where findings are robust or inconclusive, and reveals variables that influence performance. The present review also identifies areas for future research and methodological limitations. PMID:25284958

    2013-09-01

    This study examined the prevalence and reporting of date rape among female college students (aged 18-24) in Cyprus and assessed the students' attitudes and awareness regarding date rape. In addition, the study examined how date rape is perceived among representatives of related private and governmental organizations in Cyprus. This is part of a larger multi-country study. This paper will focus only on the results pertaining to Cyprus. The study was coordinated by the Mediterranean Institute of Gender Studies. This study used quantitative and qualitative methods. In total, 476 female college students responded to an anonymous questionnaire, two focus group discussions were carried out, and five key-informant interviews with relevant institutional representatives were conducted. The results of the study indicated that unwanted sexual experiences and sexual violence, including date rape, do exist among young Cypriot women. Specifically, 1.3% of the research participants reported experiencing an attempted rape by their date, and 1.9 % of the study participants reported being raped on a date. Often this was caused by their boyfriend, friend or sexual partner (54.2%). The results of the qualitative study showed that young female Cypriots agreed that many women give in to psychological pressure because they feel guilty about letting the other person down or because they 'didn't satisfy him' or fear they might lose him. Despite the explorative nature of the study, it is significant as research on date rape in Cyprus is almost non-existent. The authors anticipate that the results of the study will be useful to other researchers and policy-makers involved in this area of research.

    The redback spider ( Latrodectus hasseltii ) is nonindigenous to Japan but has now spread throughout the country. Bites to humans are rare but can be fatal. We prepared freeze-dried redback spider antivenom for therapeutic use against bites in Japan by immunization of horse plasma. This study included two nonclinical tests of the antivenom: a local irritation study involving a single intramuscular administration to rabbits (with injections of physiological saline and an existing freeze-dried diphtheria antitoxin as control and comparison substances, respectively) and a 2-week repeated intermittent intravenous-dose toxicity study in rats. The irritation study showed the antivenom's irritancy to be comparable with that of the saline and the existing antitoxin preparations under the test conditions. In a repeated-dose toxicity study, no toxicity change was found in male or female rats, and the no-observed-adverse-effect level (NOAEL) was judged to be a dose volume of 20 mL/kg (1082 units/kg antivenom activity) in both male and female rats. In addition, there was no toxicological difference between proteinaceous diphtheria antitoxin and redback spider antivenom prepared to have the same protein content and the same additive composition. Based on these findings, we will further advance our research towards clinical application of the redback spider antivenom. This research was supported by the Research Program on Emerging and Re-emerging Infectious Disease of the Japan Agency for Medical Research and Development.

  12. Biogeography

    Quattrochi, Dale A.; Arnold, James E. (Technical Monitor)

    2002-01-01

    As a field of study, biogeography may be considered a bricolage - it has been constructed from many different facets from an array of research disciplines including biology, botany, zoology, geography, and geology. Biogeography focuses on the study of the constantly changing ranges of plants and animals, over multitude of space and time scales. It also includes the study of the structure and dynamics of biotic communities and ecosystems as they relate to both natural and anthropogenic processes. As it exists today, biogeography is an interdisciplinary research area founded in both the biological and Earth sciences. From a purely biological perspective, biogeography may be perceived as one of two types of studies: 1. biotic distributions and broad scales, and interpretations of the evolutionary and dispersal history of a single taxon or a few taxa; or 2. biotic distributions at local-to-regional scales, and interpretations of these distributions in relation to contemporary environments and rates of immigration or extinction. The first type of study is what is most usually associated with the term "biogeography" as disciplinary research field. It is conventionally termed "classical biogeography" because it reflects the continuity of research foci on which biogeography was founded in the nineteenth-century. The second type of biogeographical study has more modern day roots and is termed "geographical ecology" to reflect the theoretical predilections of ecologists and population biologists. Geographical ecology for all intents has become merged with ecology and exists as a sub discipline within this larger field of study.

    Most U.S. clinical trials are funded by industry. Opportunities exist for sponsors to influence research in ways that jeopardize research objectivity. The purpose of this study was to survey U.S. medical school faculty to assess financial arrangements between investigators and industry to learn about investigators’ first hand knowledge of the effects of industry sponsorship on research. Here we show first-hand knowledge that compromises occurred in: research participants’ well-being (9%), research initiatives (35%), publication of results (28%), interpretation of research data (25%), and scientific advancement (20%) because of industry support. Financial relationships with industry were prevalent and considered important to conducting respondents’ research. PMID:19353387

    2003-01-01

    The research performed under this grant has led to an number of new insights into two general categories of fluid flows in the presence of time-dependent acceleration, as outlined briefly below. These results have been widely communicated in the scientific community through seven presentations at international conferences (4 invited, 3 contributed), five published papers (4 journal articles and 1 conference proceeding), and images from the research featured on the cover of all 2003 editions of the research journal, Nonlinearity. The work performed under this proposal also contained a substantial educational component by contributed significantly to the scientific training of one postdoctoral associate, one Ph.D. student and five undergraduate researchers. One main area of focus in this research was convective flow with time-dependent acceleration. Convection is one class of behavior that can arise from g-jitter effects. Our research focused on studies of Rayleigh-Benard system, which is an important model for understanding thermal convection; studies of this problem in the presence of acceleration modulations provided insight into the nature of g-jitter induced flow and of the effects of modulation and noise on non-equilibrium pattern formation. Our experiments on vertically vibrated Rayleigh-Benard convection demonstrated the existence of two classes of pure flow patterns (synchronous & subharmonic) patterns) that had long been predicted by theory but never before observed experimentally. Detailed studies of ranges of parameters where both classes of patterns exist simultaneously led to the discovery of a new type of patterns (called superlattices) in systems driven out of thermodynamic equilibrium.

  20. Qualitative research with small connected communities: generating new knowledge while upholding research ethics.

    PubMed

    Damianakis, Thecla; Woodford, Michael R

    2012-05-01

    Qualitative researchers have a dual mission: to generate knowledge through rigorous research and to uphold ethical standards and principles. Qualitative researchers often conduct studies with small connected communities in which relationships exist among community members. When engaging such communities, researchers might face ethical issues in upholding confidentiality standards while they work to achieve their dual mandate. Qualitative scholars have paid little attention to the ethical challenges that might arise in this context. Drawing on our experiences conducting studies with such communities, we expand the dialogue concerning qualitative research ethics by making explicit conceptual and practical tensions that emerge at various stages of the research process; articulating our respective reflective processes; and exploring issues associated with strategies for upholding confidentiality. We conclude with lessons learned to guide researchers who might face similar challenges.
