Reviews on circulating biomarkers in breast cancer usually focus on one single biomarker or a selective group of biomarkers. An overview summarizing the discovery and evaluation of all blood-based biomarkers in metastatic breast cancer is lacking. This systematic review aims to identify the available evidence of known blood-based biomarkers in metastatic breast cancer, regarding their clinical utility and state-of-the-art position in the validation process. The initial search yielded 1078 original studies, of which 420 were assessed for eligibility. A total of 320 studies were included in the final synthesis. A Development, Evaluation and Application Chart (DEAC) of all biomarkers was developed. Most studies focus on identifying new biomarkers and search for relations between these biomarkers and traditional molecular characteristics. Biomarkers are usually investigated in only one study (68.8%). Only 9.8% of all biomarkers was investigated in more than five studies. Circulating tumor cells, gene expression within tumor cells and the concentration of secreted proteins are the most frequently investigated biomarkers in liquid biopsies. However, there is a lack of studies focusing on identifying the clinical utility of these biomarkers, by which the additional value still seems to be limited according to the investigated evidence.

Evidence shows ethnic-inequality is a very effective variable in the Community and individual health associated outcomes. This study focused on gaining a deeper understanding of people's perception on inequality of health in Iranian-Kurds and its determinants. The study was conducted in the three cities of Marivan, Sanandaj (capital of Kurdistan province in Iran) and Tehran (capital of the country). The study was conducted through 34 in-depth interviews and ten focus group discussions with health services users, academic graduates and health delivery service personnel. Consensus on social, mental and physical health inequality did not exist within the study participants. However, there were concerns about differences in healthcare access and utilization. Several participants believed that access to health services and socio-cultural differences of Kurds affected the healthcare utilization. Since, people perceived ethnic-inequality in healthcare access and utilization, ethnicity must be considered as a mandatory stratifier in monitoring health status and a concern during planning health interventions. People's awareness, resources management and allocation are factors requiring more consideration when choosing policy options.

Zhou, Y.; Santini, D.; Rood, M.

Using 2014 U.S. light duty PEV registrations by make and model, this paper assesses the causes of Plug-in Electric Vehicle (PEV) success across U.S. states focusing on areas that had incentive and utility programs supporting PEV adoption. Market segments investigated were (1) luxury/performance (>$60,000 list price), (2) mid-market ($40-50,000), (3) mass market (<$40.000), and (4) total. States with either exclusive or preferential BEV incentives are a focus. BEV-biased incentives proved to be very effective in promoting mass market BEVs. After controlling for these attributes, case studies for several utility service areas were conducted to gauge whether PEVs were more ormore » less successfully implemented via outreach by those utilities. These investigations suggest ways that utilities can successfully increase PEV registrations, after taking local climate and state incentives into consideration.« less

Comparing hospital staff and patient perceptions of customer service: a pilot study utilizing survey and focus group data.

Fottler, Myron D; Dickson, Duncan; Ford, Robert C; Bradley, Kenneth; Johnson, Lee

2006-02-01

The measurement of patient satisfaction is crucial to enhancing customer service and competitive advantage in the health-care industry. While there are numerous approaches to such measurement, this paper provides a case study which compares and contrasts patient and staff perceptions of customer service using both survey and focus group data. Results indicate that there is a high degree of correlation between staff and patient perceptions of customer service based on both survey and focus group data. However, the staff and patient subgroups also provided complementary information regarding patient perceptions of their service experience. Staff members tended to have more negative perceptions of service attributes than did the patients themselves. The focus group results provide complementary information to survey results in terms of greater detail and more managerially relevant information. While these results are derived from a pilot study, they suggest that diversification of data sources beyond patient surveys may enhance the utility of customer service information. If further research can affirm these findings, they create exciting possibilities for gathering valid, reliable and cost-effective customer service information.

Medical pluralism of the Chinese in London: an exploratory study.

PubMed

Rochelle, Tina L; Marks, David F

2010-11-01

This study was designed to examine the extent of medical pluralism among the Chinese in London. Members of the London Chinese community were recruited through Chinese organizations in London and participated in six focus groups. A total of 48 Chinese men and women aged 24-74 years were asked to talk about their health behaviour and health utilization patterns. Transcripts of the focus group discussions underwent thematic analysis to explore and describe the utilization of traditional Chinese medicine (TCM) and Western medicine (WM) of informants and factors that impacted on utilization. Findings focus on participants' evaluation of TCM and WM as two systems of health provision, how informants used these two health systems, and the reasons associated with use of these two systems. Utilization of TCM and WM varied. Concurrent use of TCM and WM was common. The National Health Service was generally perceived as difficult to use, with concerns over the language barrier, and communicating with and being able to trust health providers. The UK TCM trade was perceived as being aimed at the non-Chinese market and there were issues of trust related to the regulation of UK TCM. Although none of these issues are unique to the Chinese in the UK, previous experience with different approaches to health care, particularly TCM, may make the experience of such barriers more extreme.

Mixed Methods in Prostate Cancer Prevention and Service Utilization Planning: Combining Focus Groups, Survey Research, and Community Engagement.

PubMed

Tataw, David Besong; Ekúndayò, Olúgbémiga T

2017-01-01

This article reports on the use of sequential and integrated mixed-methods approach in a focused population and small-area analysis. The study framework integrates focus groups, survey research, and community engagement strategies in a search for evidence related to prostate cancer screening services utilization as a component of cancer prevention planning in a marginalized African American community in the United States. Research and data analysis methods are synthesized by aggregation, configuration, and interpretive analysis. The results of synthesis show that qualitative and quantitative data validate and complement each other in advancing our knowledge of population characteristics, variable associations, the complex context in which variables exist, and the best options for prevention and service planning. Synthesis of findings and interpretive analysis provided two important explanations which seemed inexplicable in regression outputs: (a) Focus group data on the limitations of the church as an educational source explain the negative association between preferred educational channels and screening behavior found in quantitative analysis. (b) Focus group data on unwelcoming provider environments explain the inconsistent relationship between knowledge of local sites and screening services utilization found in quantitative analysis. The findings suggest that planners, evaluators, and scientists should grow their planning and evaluation evidence from the community they serve.

The construction of standard gamble utilities.

PubMed

van Osch, Sylvie M C; Stiggelbout, Anne M

2008-01-01

Health effects for cost-effectiveness analysis are best measured in life years, with quality of life in each life year expressed in terms of utilities. The standard gamble (SG) has been the gold standard for utility measurement. However, the biases of probability weighting, loss aversion, and scale compatibility have an inconclusive effect on SG utilities. We determined their effect on SG utilities using qualitative data to assess the reference point and the focus of attention. While thinking aloud, 45 healthy respondents provided SG utilities for six rheumatoid arthritis health states. Reference points, goals, and focuses of attention were coded. To assess the effect of scale compatibility, correlations were assessed between focus of attention and mean utility. The certain outcome served most frequently as reference point, the SG was perceived as a mixed gamble. Goals were mostly mentioned with respect to this outcome. Scale compatibility led to a significant upward bias in utilities; attention lay relatively more on the low outcome and this was positively correlated with mean utility. SG utilities should be corrected for loss aversion and probability weighting with the mixed correction formula proposed by prospect theory. Scale compatibility will likely still bias SG utilities, calling for research on a correction. Copyright (c) 2007 John Wiley & Sons, Ltd.

In the end stages of life, drug treatment goals shift to symptom control and quality of life and as such changes in drug utilization are expected. The aim of this paper is to review the extent to which costs are considered in drug utilization research at the end of life, with a particular focus on the outcome measures being used. This systematic review identified seven studies across varied settings studies reporting both drug utilization and medication cost outcome measures. The main factors identified that impacted medication use and cost were the time period considered and the provision of specialist palliative care services. Combining drug utilization and medication cost outcomes is critical for the allocation of healthcare resources and the development of a sound health policy.

Buss, I C; Halfens, R J; Abu-Saad, H H; Kok, G

1999-01-01

The importance of research-based practice in nursing has been frequently stressed, and a number of nursing studies have been conducted whose results enable nursing to improve knowledge and practice. This study reports a literature review in which the current status of knowledge and research utilization with regard to pressure sores is described. This review first gives an overview of studies on knowledge utilization in general and shows that the spontaneous diffusion of knowledge is inappropriate. Furthermore, an overview of planned research utilization activities focusing on pressure sore prevention and treatment in nursing is presented. The results of these studies show that planned research utilization activities performed in individual organizations lead to positive outcomes in almost all cases. Therefore, it could be concluded that implementing planned research utilization activities in individual health care institutions seems to be an effective strategy to decrease pressure sore incidence and prevalence rates.

Cost-Utility Analysis of Cancer Prevention, Treatment, and Control: A Systematic Review.

2016-02-01

Substantial innovation related to cancer prevention and treatment has occurred in recent decades. However, these innovations have often come at a significant cost. Cost-utility analysis provides a useful framework to assess if the benefits from innovation are worth the additional cost. This systematic review on published cost-utility analyses related to cancer care is from 1988 through 2013. Analyses were conducted in 2013-2015. This review analyzed data from the Tufts Medical Center Cost-Effectiveness Analysis Registry (www.cearegistry.org), a comprehensive registry with detailed information on 4,339 original cost-utility analyses published in the peer-reviewed medical and economic literature through 2013. There were 721 cancer-related cost-utility analyses published from 1998 through 2013, with roughly 12% of studies focused on primary prevention and 17% focused on secondary prevention. The most often studied cancers were breast cancer (29%); colorectal cancer (11%); and prostate cancer (8%). The median reported incremental cost-effectiveness ratios (in 2014 U.S. dollars) were $25,000 for breast cancer, $24,000 for colorectal cancer, and $34,000 for prostate cancer. The current evidence indicates that there are many interventions that are cost effective across cancer sites and levels of prevention. However, the results highlight the relatively small number of cancer cost-utility analyses devoted to primary prevention compared with secondary or tertiary prevention.

Bringing radical behaviorism to revolutionary Brazil and back: Fred Keller's Personalized System of Instruction and Cold War engineering education.

PubMed

Akera, Atsushi

2017-09-01

This article traces the shifting epistemic commitments of Fred S. Keller and his behaviorist colleagues during their application of Skinnerian radical behaviorism to higher education pedagogy. Building on prior work by Alexandra Rutherford and her focus on the successive adaptation of Skinnerian behaviorism during its successive applications, this study utilizes sociologist of science Karin Knorr Cetina's concept of epistemic cultures to more precisely trace the changes in the epistemic commitments of a group of radical behaviorists as they shifted their focus to applied behavioral analysis. The story revolves around a self-paced system of instruction known as the Personalized System of Instruction, or PSI, which utilized behaviorist principles to accelerate learning within the classroom. Unlike Skinner's entry into education, and his focus on educational technologies, Keller developed a mastery-based approach to instruction that utilized generalized reinforcers to cultivate higher-order learning behaviors. As it happens, the story also unfolds across a rather fantastic political terrain: PSI originated in the context of Brazilian revolutionary history, but circulated widely in the U.S. amidst Cold War concerns about an engineering manpower(sic) crisis. This study also presents us with an opportunity to test Knorr Cetina's conjecture about the possible use of a focus on epistemic cultures in addressing a classic problem in the sociology of science, namely unpacking the relationship between knowledge and its social context. Ultimately, however, this study complements another historical case study in applied behavioral analysis, where a difference in outcome helps to lay out the range of possible shifts in the epistemic commitments of radical behaviorists who entered different domains of application. The case study also has some practical implications for those creating distance learning environments today, which are briefly explored in the conclusion. © 2017 Wiley Periodicals, Inc.

No current guidance is available in the UK on the choice of preference-based measure (PBM) that should be used in obtaining health-related quality of life from children. The aim of this study is to review the current usage of PBMs for obtaining health state utility values in child and adolescent populations, and to obtain information on patient and parent-proxy respondent preferences in completing PBMs in the UK. A literature review was conducted to determine which instrument is most frequently used for child-based economic evaluations and whether child or proxy responses are used. Instruments were compared on dimensions, severity levels, elicitation and valuation methods, availability of value sets and validation studies, and the range of utility values generated. Additionally, a series of focus groups of parents and young people (11-20 years) were convened to determine patient and proxy preferences. Five PBMs suitable for child populations were identified, although only the Health Utilities Index 2 (HUI2) and Child Heath Utility 9D (CHU-9D) have UK value sets. 45 papers used PBMs in this population, but many used non-child-specific PBMs. Most respondents were parent proxies, even in adolescent populations. Reported missing data ranged from 0.5 to 49.3%. The focus groups reported their experiences with the EQ-5D-Y and CHU-9D. Both the young persons' group and parent/proxy groups felt that the CHU-9D was more comprehensive but may be harder for a proxy to complete. Some younger children had difficulty understanding the CHU-9D questions, but the young persons' group nonetheless preferred responding directly. The use of PBMs in child populations is increasing, but many studies use PBMs that do not have appropriate value sets. Parent proxies are the most common respondents, but the focus group responses suggest it would be preferred, and may be more informative, for older children to self-report or for child-parent dyads to respond.

Essential tremor remains a very common yet medically refractory condition. A recent phase 3 study demonstrated that magnetic resonance-guided focused ultrasound thalamotomy significantly improved upper limb tremor. The objectives of this study were to assess this novel therapy's cost-effectiveness compared with existing procedural options. Literature searches of magnetic resonance-guided focused ultrasound thalamotomy, DBS, and stereotactic radiosurgery for essential tremor were performed. Pre- and postoperative tremor-related disability scores were collected from 32 studies involving 83 magnetic resonance-guided focused ultrasound thalamotomies, 615 DBSs, and 260 stereotactic radiosurgery cases. Utility, defined as quality of life and derived from percent change in functional disability, was calculated; Medicare reimbursement was employed as a proxy for societal cost. Medicare reimbursement rates are not established for magnetic resonance-guided focused ultrasound thalamotomy for essential tremor; therefore, reimbursements were estimated to be approximately equivalent to stereotactic radiosurgery to assess a cost threshold. A decision analysis model was constructed to examine the most cost-effective option for essential tremor, implementing meta-analytic techniques. Magnetic resonance-guided focused ultrasound thalamotomy resulted in significantly higher utility scores compared with DBS (P < 0.001) or stereotactic radiosurgery (P < 0.001). Projected costs of magnetic resonance-guided focused ultrasound thalamotomy were significantly less than DBS (P < 0.001), but not significantly different from radiosurgery. Magnetic resonance-guided focused ultrasound thalamotomy is cost-effective for tremor compared with DBS and stereotactic radiosurgery and more effective than both. Even if longer follow-up finds changes in effectiveness or costs, focused ultrasound thalamotomy will likely remain competitive with both alternatives. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

Previous studies on school-based mindfulness and yoga programs have focused primarily on quantitative measurement of program outcomes. This study used qualitative data to investigate program content and skills that students remembered and applied in their daily lives. Data were gathered following a 16-week mindfulness and yoga intervention delivered at three urban schools by a community non-profit organization. We conducted focus groups and interviews with nine classroom teachers who did not participate in the program and held six focus groups with 22 fifth and sixth grade program participants. This study addresses two primary research questions: (1) What skills did students learn, retain, and utilize outside the program? and (2) What changes did classroom teachers expect and observe among program recipients? Four major themes related to skill learning and application emerged as follows: (1) youths retained and utilized program skills involving breath work and poses; (2) knowledge about health benefits of these techniques promoted self-utilization and sharing of skills; (3) youths developed keener emotional appraisal that, coupled with new and improved emotional regulation skills, helped de-escalate negative emotions, promote calm, and reduce stress; and (4) youths and teachers reported realistic and optimistic expectations for future impact of acquired program skills. We discuss implications of these findings for guiding future research and practice. PMID:26918064

Van Puymbroeck, Marieke; Miller, Kristine K.; Dickes, Lori A.; Schmid, Arlene A.

2015-01-01

Inpatient medical rehabilitation has maintained a typical medical-model focus and structure for many years. However, as integrative therapies, such as yoga therapy, emerge as treatments which can enhance the physical and mental health of its participants, it is important to determine if they can be easily implemented into the traditional rehabilitation structure and milieu. Therefore, the purpose of this study was to examine the perceptions of key agency personnel on the feasibility and utility of yoga therapy implemented in inpatient rehabilitation. This study reports the results of focus groups and an individual interview with key stakeholders (administrators and rehabilitation therapists) from two rehabilitation hospitals following the implementation of yoga therapy. Results focused on several key themes: feasibility from the therapist and administrator perspectives, challenges to implementation, and utility and benefit. Overall, the implementation and integration of yoga therapy were positive; however, some programmatic and policy and organizational considerations remain. Implications for practice and future research are provided. PMID:26491457

Quality-of-Life Assessment of Fibroid Treatment Options and Outcomes

PubMed Central

Kong, Chung Yin; Tempany, Clare M.; Swan, J. Shannon

2011-01-01

Purpose: To obtain utilities (a unit of measure of a person’s relative preferences for different health states compared with death or worst possible outcome) for uterine fibroids before and after treatment and to measure short-term utilities for the following uterine fibroid treatments: abdominal hysterectomy, magnetic resonance (MR) imaging–guided focused ultrasound surgery, and uterine artery embolization (UAE). Materials and Methods: This retrospective study was approved by the institutional review board and was HIPAA compliant. The waiting trade-off (WTO) method, a variation on the time trade-off (TTO) method, is used to obtain utilities for diagnostic procedures on the basis of the fact that people wait longer to avoid noxious tests and/or procedures. The WTO method provides short-term quality of life tolls in terms of quality-adjusted life-weeks by scaling wait times with pre- and posttreatment utilities. Utilities for uterine fibroids before and after treatment were obtained with the TTO method and a visual analog scale (VAS) by using a questionnaire administered by means of a phone interview. WTO wait times were adjusted for quality of life with VAS and TTO utilities and a transformation of VAS. Wait times were compared by using nonparametric tests. The study participants included 62 patients who had undergone abdominal hysterectomy, 74 who had undergone UAE, and 61 who had undergone MR imaging–guided focused ultrasound surgery. Results: Quality of life increased with all treatments. The median WTO wait time was higher for hysterectomy (21.6 weeks) than for UAE or MR imaging–guided focused ultrasound surgery (14.1 weeks for both) (P < .05). Quality-adjusted life-week tolls were smaller when scaled according to TTO than when scaled according to VAS or transformation of VAS. Conclusion: Quality of life increased after all fibroid treatments. WTO is feasible for assessing the quality-adjusted morbidity of treatment procedures. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11100704/-/DC1 PMID:21364084

An Assessment Model for Energy Efficiency Program Planning in Electric Utilities: Case of the Pacific of Northwest U.S.A

NASA Astrophysics Data System (ADS)

Iskin, Ibrahim

Energy efficiency stands out with its potential to address a number of challenges that today's electric utilities face, including increasing and changing electricity demand, shrinking operating capacity, and decreasing system reliability and flexibility. Being the least cost and least risky alternative, the share of energy efficiency programs in utilities' energy portfolios has been on the rise since the 1980s, and their increasing importance is expected to continue in the future. Despite holding great promise, the ability to determine and invest in only the most promising program alternatives plays a key role in the successful use of energy efficiency as a utility-wide resource. This issue becomes even more significant considering the availability of a vast number of potential energy efficiency programs, the rapidly changing business environment, and the existence of multiple stakeholders. This dissertation introduces hierarchical decision modeling as the framework for energy efficiency program planning in electric utilities. The model focuses on the assessment of emerging energy efficiency programs and proposes to bridge the gap between technology screening and cost/benefit evaluation practices. This approach is expected to identify emerging technology alternatives which have the highest potential to pass cost/benefit ratio testing procedures and contribute to the effectiveness of decision practices in energy efficiency program planning. The model also incorporates rank order analysis and sensitivity analysis for testing the robustness of results from different stakeholder perspectives and future uncertainties in an attempt to enable more informed decision-making practices. The model was applied to the case of 13 high priority emerging energy efficiency program alternatives identified in the Pacific Northwest, U.S.A. The results of this study reveal that energy savings potential is the most important program management consideration in selecting emerging energy efficiency programs. Market dissemination potential and program development and implementation potential are the second and third most important, whereas ancillary benefits potential is the least important program management consideration. The results imply that program value considerations, comprised of energy savings potential and ancillary benefits potential; and program feasibility considerations, comprised of program development and implementation potential and market dissemination potential, have almost equal impacts on assessment of emerging energy efficiency programs. Considering the overwhelming number of value-focused studies and the few feasibility-focused studies in the literature, this finding clearly shows that feasibility-focused studies are greatly understudied. The hierarchical decision model developed in this dissertation is generalizable. Thus, other utilities or power systems can adopt the research steps employed in this study as guidelines and conduct similar assessment studies on emerging energy efficiency programs of their interest.

Health State Utility Values for Age-Related Macular Degeneration: Review and Advice.

PubMed

Butt, Thomas; Tufail, Adnan; Rubin, Gary

2017-02-01

Health state utility values are a major source of uncertainty in economic evaluations of interventions for age-related macular degeneration (AMD). This review identifies and critiques published utility values and methods for eliciting de novo utility values in AMD. We describe how utility values have been used in healthcare decision making and provide guidance on the choice of utility values for future economic evaluations for AMD. Literature was searched using PubMed, and health technology assessments (HTA) were searched using HTA agency websites to identify articles reporting utility values or approaches to derive utility values in AMD and articles applying utilities for use in healthcare decision making relating to treatments for AMD. A total of 70 studies qualified for data extraction, 22 of which were classified as containing utility values and/or elicitation methods, and 48 were classified as using utility values in decision making. A large number of studies have elicited utility values for AMD, although those applied to decision making have focused on a few of these. There is an appreciation of the challenges in the measurement and valuation of health states, with recent studies addressing challenges such as the insensitivity of generic health-related quality of life (HRQoL) questionnaires and utility in the worse-seeing eye. We would encourage careful consideration when choosing utility values in decision making and an explicit critique of their applicability to the decision problem.

The utilization and impact of the studies published using the National Cancer Database (NCDB) is currently unclear. In this study, we aim to characterize the published studies, and identify relatively unexplored areas for future investigations. A literature search was performed using PubMed in January 2017 to identify all papers published using NCDB data. Characteristics of the publications were extracted. Citation frequencies were obtained through the Web of Science. Three hundred 2 articles written by 230 first authors met the inclusion criteria. The number of publications grew exponentially since 2013, with 108 articles published in 2016. Articles were published in 86 journals. The majority of the published papers focused on digestive system cancer, while bone and joints, eye and orbit, myeloma, mesothelioma, and Kaposi Sarcoma were never studied. Thirteen institutions in the United States were associated with more than 5 publications. The papers have been cited for a total of 9858 times since the publication of the first paper in 1992. Frequently appearing keywords congregated into 3 clusters: "demographics," "treatments and survival," and "statistical analysis method." Even though the main focuses of the articles captured a extremely wide range, they can be classified into 2 main categories: survival analysis and characterization. Other focuses include database(s) analysis and/or comparison, and hospital reporting. The surging interest in the use of NCDB is accompanied by unequal utilization of resources by individuals and institutions. Certain areas were relatively understudied and should be further explored.

This study examined relationships between workplace stress, organizational factors and use of EAP counseling services delivered by network providers in a large, privately-insured population. Claims data were linked to measures of workplace stress, focus on wellness/prevention, EAP promotion, and EAP activities for health care plan enrollees from 26 employers. The association of external environment and work organization variables with use of EAP counseling services was examined. Higher levels of EAP promotion and worksite activities were associated with greater likelihood of service use. Greater focus on wellness/prevention and unusual and significant stress were associated with lower likelihood of service use. Results provide stakeholders with insights on approaches to increasing utilization of EAP services.

Utilization-focused evaluation of a STEM enrichment program

NASA Astrophysics Data System (ADS)

Carter, Sally

The purpose of this study was to determine the impact and utilization of a STEM enrichment program (hereafter referred to as The Program). The Program consisted of two parts. First an educator resource center provided free educational materials throughout The Program’s home state. The second part of The Program was a network of education specialists who provided professional development for teachers, modeled lessons with students, and provided presentations for the general public. The problem addressed by this study was a lack of knowledge regarding the impact of The Program. The Program’s director requested a utilization-focused program evaluation to answer thirteen questions. Questions covered Program impact for five areas: overall impact on teachers, overall impact on students, overall impact of materials, overall impact of Program personnel, and overall impact on STEM education. A mixed-methods case study was designed to gather data. Quantitative data included Program archival data regarding the number of contacts and a survey distributed to teachers who had used The Program’s services on at least one occasion. Qualitative data included written comments gathered from the teacher surveys, seven teacher focus groups, and four Program personnel interviews. Data found an overall positive Program impact in all five areas. Both quantitative and qualitative data showed favorable perceptions by teachers and Program personnel. It is not known if data from this case study can be generalized to other STEM enrichment programs. Future research might include a study to determine if The Program’s model could be used to generate new STEM enrichment programs.

Urban Underground Pipelines Mapping Using Ground Penetrating Radar

NASA Astrophysics Data System (ADS)

Jaw, S. W.; M, Hashim

2014-02-01

Underground spaces are now being given attention to exploit for transportation, utilities, and public usage. The underground has become a spider's web of utility networks. Mapping of underground utility pipelines has become a challenging and difficult task. As such, mapping of underground utility pipelines is a "hit-and-miss" affair, and results in many catastrophic damages, particularly in urban areas. Therefore, this study was conducted to extract locational information of the urban underground utility pipeline using trenchless measuring tool, namely ground penetrating radar (GPR). The focus of this study was to conduct underground utility pipeline mapping for retrieval of geometry properties of the pipelines, using GPR. In doing this, a series of tests were first conducted at the preferred test site and real-life experiment, followed by modeling of field-based model using Finite-Difference Time-Domain (FDTD). Results provide the locational information of underground utility pipelines associated with its mapping accuracy. Eventually, this locational information of the underground utility pipelines is beneficial to civil infrastructure management and maintenance which in the long term is time-saving and critically important for the development of metropolitan areas.

Can focused trauma education initiatives reduce mortality or improve resource utilization in a low-resource setting?

Over 90% of injury deaths occur in low-income countries. Evaluating the impact of focused trauma courses in these settings is challenging. We hypothesized that implementation of a focused trauma education initiative in a low-income country would result in measurable differences in injury-related outcomes and resource utilization. Two 3-day trauma education courses were conducted in the Rwandan capital over a one-month period (October-November, 2011). An ATLS provider demonstration course was delivered to 24 faculty surgeons and 15 Rwandan trauma nurse auditors, and a Canadian Network for International Surgery Trauma Team Training (TTT) course was delivered to 25 faculty, residents, and nurses. Trauma registry data over the 6 months prior to the courses were compared to the 6 months afterward with emergency department (ED) mortality as the primary endpoint. Secondary endpoints included radiology utilization and early procedural interventions. Univariate analyses were conducted using χ(2) and Fisher's exact test. A total of 798 and 575 patients were prospectively studied during the pre-intervention and post-intervention periods, respectively. Overall mortality of injured patients decreased after education implementation from 8.8 to 6.3%, but was not statistically significant (p = 0.09). Patients with an initial Glasgow Coma Score (GCS) of 3-8 had the highest injury-related mortality, which significantly decreased from 58.5% (n = 55) to 37.1% (n = 23), (p = 0.009, OR 0.42, 95% CI 0.22-0.81). There was no statistical difference in the rates of early intubation, cervical collar use, imaging studies, or transfusion in the overall cohort or the head injury subset. When further stratified by GCS, patients with an initial GCS of 3-5 in the post-intervention period had higher utilization of head CT scans and chest X-rays. The mortality of severely injured patients decreased after initiation of focused trauma education courses, but no significant increase in resource utilization was observed. The explanation may be complex and multi-factorial. Long-term multidisciplinary efforts that pair training with changes in resources and mentorship may be needed to produce broad and lasting changes in the overall care system.

Time reversal focusing of high amplitude sound in a reverberation chamber.

Time reversal (TR) is a signal processing technique that can be used for intentional sound focusing. While it has been studied in room acoustics, the application of TR to produce a high amplitude focus of sound in a room has not yet been explored. The purpose of this study is to create a virtual source of spherical waves with TR that are of sufficient intensity to study nonlinear acoustic propagation. A parameterization study of deconvolution, one-bit, clipping, and decay compensation TR methods is performed to optimize high amplitude focusing and temporal signal focus quality. Of all TR methods studied, clipping is shown to produce the highest amplitude focal signal. An experiment utilizing eight horn loudspeakers in a reverberation chamber is done with the clipping TR method. A peak focal amplitude of 9.05 kPa (173.1 dB peak re 20 μPa) is achieved. Results from this experiment indicate that this high amplitude focusing is a nonlinear process.

Health seeking behaviour and health service utilization in Pakistan: challenging the policy makers.

PubMed

Shaikh, Babar T; Hatcher, Juanita

2005-03-01

There is a growing literature on health seeking behaviours and the determinants of health services utilization especially in the context of developing countries. However, very few focused studies have been seen in Pakistan in this regard. This paper presents an extensive literature review of the situation in developing countries and relates the similar factors responsible for shaping up of a health seeking behaviour and health service utilization in Pakistan. The factors determining the health behaviours may be seen in various contexts: physical, socio-economic, cultural and political. Therefore, the utilization of a health care system, public or private, formal or non-formal, may depend on socio-demographic factors, social structures, level of education, cultural beliefs and practices, gender discrimination, status of women, economic and political systems environmental conditions, and the disease pattern and health care system itself. Policy makers need to understand the drivers of health seeking behaviour of the population in an increasingly pluralistic health care system. Also a more concerted effort is required for designing behavioural health promotion campaigns through inter-sectoral collaboration focusing more on disadvantaged segments of the population.

Three-dimensional patterning in polymer optical waveguides using focused ion beam milling

NASA Astrophysics Data System (ADS)

Kruse, Kevin; Burrell, Derek; Middlebrook, Christopher

2016-07-01

Waveguide (WG) photonic-bridge taper modules are designed for symmetric planar coupling between silicon WGs and single-mode fibers (SMFs) to minimize photonic chip and packaging footprint requirements with improving broadband functionality. Micromachined fabrication and evaluation of polymer WG tapers utilizing high-resolution focused ion beam (FIB) milling is performed and presented. Polymer etch rates utilizing the FIB and optimal methods for milling polymer tapers are identified for three-dimensional patterning. Polymer WG tapers with low sidewall roughness are manufactured utilizing FIB milling and optically tested for fabrication loss. FIB platforms utilize a focused beam of ions (Ga+) to etch submicron patterns into substrates. Fabricating low-loss polymer WG taper prototypes with the FIB before moving on to mass-production techniques provides theoretical understanding of the polymer taper and its feasibility for connectorization devices between silicon WGs and SMFs.

Teach It, Don't Preach It: The Differential Effects of Directly-communicated and Self-generated Utility Value Information.

PubMed

Canning, Elizabeth A; Harackiewicz, Judith M

2015-03-01

Social-psychological interventions in education have used a variety of "self-persuasion" or "saying-is-believing" techniques to encourage students to articulate key intervention messages. These techniques are used in combination with more overt strategies, such as the direct communication of messages in order to promote attitude change. However, these different strategies have rarely been systematically compared, particularly in controlled laboratory settings. We focus on one intervention based in expectancy-value theory designed to promote perceptions of utility value in the classroom and test different intervention techniques to promote interest and performance. Across three laboratory studies, we used a mental math learning paradigm in which we varied whether students wrote about utility value for themselves or received different forms of directly-communicated information about the utility value of a novel mental math technique. In Study 1, we examined the difference between directly-communicated and self-generated utility-value information and found that directly-communicated utility-value information undermined performance and interest for individuals who lacked confidence, but that self-generated utility had positive effects. However, Study 2 suggests that these negative effects of directly-communicated utility value can be ameliorated when participants are also given the chance to generate their own examples of utility value, revealing a synergistic effect of directly-communicated and self-generated utility value. In Study 3, we found that individuals who lacked confidence benefited more when everyday examples of utility value were communicated, rather than career and school examples.

Appraising longitudinal trends in the strategic risks cited by risk managers in the international water utility sector, 2005-2015.

We report dynamic changes in the priorities for strategic risks faced by international water utilities over a 10year period, as cited by managers responsible for managing them. A content analysis of interviews with three cohorts of risk managers in the water sector was undertaken. Interviews probed the focus risk managers' were giving to strategic risks within utilities, as well as specific questions on risk analysis tools (2005); risk management cultures (2011) and the integration of risk management with corporate decision-making (2015). The coding frequency of strategic (business, enterprise, corporate) risk terms from 18 structured interviews (2005) and 28 semi-structured interviews (12 in 2011; 16 in 2015) was used to appraise changes in the perceived importance of strategic risks within the sector. The aggregated coding frequency across the study period, and changes in the frequency of strategic risks cited at three interview periods identified infrastructure assets as the most significant risk over the period and suggests an emergence of extrinsic risk over time. Extended interviews with three utility risk managers (2016) from the UK, Canada and the US were then used to contextualise the findings. This research supports the ongoing focus on infrastructure resilience and the increasing prevalence of extrinsic risk within the water sector, as reported by the insurance sector and by water research organisations. The extended interviews provided insight into how strategic risks are now driving the implementation agenda within utilities, and into how utilities can secure tangible business value from proactive risk governance. Strategic external risks affecting the sector are on the rise, involve more players and are less controllable from within a utility's own organisational boundaries. Proportionate risk management processes and structures provide oversight and assurance, whilst allowing a focus on the tangible business value that comes from managing strategic risks well.

With an eye toward future primary prevention efforts, this study explores perceptions of inhalant utility among young adolescents in the United States. The study makes use of data gathered via nine focus groups conducted in Tucson, Arizona in 2004 (N = 47, mean age = 13.2 years). Three main themes emerged concerning the perceived utility of inhalant use: (1) Inhalant use as a means of mental escape, (2) Inhalant use as a social tool, and (3) Inhalant use as a parental relations tool. Additionally, participants discussed an interaction hypothesis regarding inhalant use and popularity. Implications for future research are suggested and limitations described.

Adoption of innovations, whether new ideas, technologies, or products, is crucially important to knowledge societies. The landmark studies of adoption dealt with innovations having great societal impact (such as antibiotics or hybrid crops) but where determining the utility of the innovation was straightforward (such as fewer side effects or greater yield). Recent large-scale studies of adoption were conducted within heterogeneous populations and focused on products with little societal impact. Here, we focus on a case with great practical significance: adoption by small groups of highly trained individuals of innovations with large societal impact but for which it is impractical to determine the true utility of the innovation. Specifically, we study experimentally the adoption by critical care physicians of a diagnostic assay that complements current protocols for the diagnosis of life-threatening bacterial infections and for which a physician cannot estimate the true accuracy of the assay based on personal experience. We show through computational modeling of the experiment that infection-spreading models—which have been formalized as generalized contagion processes—are not consistent with the experimental data, while a model inspired by opinion models is able to reproduce the empirical data. Our modeling approach enables us to investigate the efficacy of different intervention schemes on the rate and robustness of innovation adoption in the real world. While our study is focused on critical care physicians, our findings have implications for other settings in education, research, and business, where small groups of highly qualified peers make decisions about the adoption of innovations whose utility is difficult if not impossible to gauge.

Here, we focus on a case with great practical significance: adoption by small groups of highly trained individuals of innovations with large societal impact but for which it is impractical to determine the true utility of the innovation. Specifically, we study experimentally the adoption by critical care physicians of a diagnostic assay that complements current protocols for the diagnosis of life-threatening bacterial infections and for which a physician cannot estimate the true accuracy of the assay based on personal experience. We show through computational modeling of the experiment that infection-spreading models-which have been formalized as generalized contagion processes-are not consistent with the experimental data, while a model inspired by opinion models is able to reproduce the empirical data. Our modeling approach enables us to investigate the efficacy of different intervention schemes on the rate and robustness of innovation adoption in the real world. While our study is focused on critical care physicians, our findings have implications for other settings in education, research, and business, where small groups of highly qualified peers make decisions about the adoption of innovations whose utility is difficult if not impossible to gauge.

Development of an evidence-based decision pathway for vestibular schwannoma treatment options.

Linkov, Faina; Valappil, Benita; McAfee, Jacob; Goughnour, Sharon L; Hildrew, Douglas M; McCall, Andrew A; Linkov, Igor; Hirsch, Barry; Snyderman, Carl

To integrate multiple sources of clinical information with patient feedback to build evidence-based decision support model to facilitate treatment selection for patients suffering from vestibular schwannomas (VS). This was a mixed methods study utilizing focus group and survey methodology to solicit feedback on factors important for making treatment decisions among patients. Two 90-minute focus groups were conducted by an experienced facilitator. Previously diagnosed VS patients were recruited by clinical investigators at the University of Pittsburgh Medical Center (UPMC). Classical content analysis was used for focus group data analysis. Providers were recruited from practices within the UPMC system and were surveyed using Delphi methods. This information can provide a basis for multi-criteria decision analysis (MCDA) framework to develop a treatment decision support system for patients with VS. Eight themes were derived from these data (focus group + surveys): doctor/health care system, side effects, effectiveness of treatment, anxiety, mortality, family/other people, quality of life, and post-operative symptoms. These data, as well as feedback from physicians were utilized in building a multi-criteria decision model. The study illustrated steps involved in the development of a decision support model that integrates evidence-based data and patient values to select treatment alternatives. Studies focusing on the actual development of the decision support technology for this group of patients are needed, as decisions are highly multifactorial. Such tools have the potential to improve decision making for complex medical problems with alternate treatment pathways. Copyright © 2016 Elsevier Inc. All rights reserved.

Skill Acquisition and Utilization During Evidence-Based Psychosocial Treatments for Childhood Disruptive Behavior Problems: A Review and Meta-analysis

PubMed Central

Higa, Janelle; Trentacosta, Christopher J.; Herschell, Amy D.; Kolko, David J.

2013-01-01

We review 85 empirical articles published since 2000 that measured the acquisition and/or utilization of parent management skills and/or child cognitive-behavioral skills in the context of an evidence-based treatment (EBT) for childhood behavior problems. Results showed that: (1) there are no standardized measures of skill acquisition or skill utilization that are used across treatments, (2) little is known about predictors, correlates, or outcomes associated with skill acquisition and utilization, and (3) few studies systematically examined techniques to enhance the acquisition and utilization of specific skills. Meta-analytic results from a subset of 68 articles (59 studies) showed an overall treatment–control ES =.31, p < .01 for skill acquisition and ES =.20, p = ns for skill utilization. We recommend that future research focus on the following three areas: (1) development of standardized measures of skill acquisition and utilization from a “common elements” perspective that can used across EBTs; (2) assessment of the predictors, correlates, and outcomes associated with skill acquisition and utilization; and (3) development of innovative interventions to enhance the acquisition and utilization of cognitive-behavioral and parent management skills.

Imazawa, Ryota; Kawano, Yasunori; Itami, Kiyoshi

2015-07-01

This study solves the Grad-Shafranov equation with a fixed plasma boundary by utilizing a meshless method for the first time. Previous studies have utilized a finite element method (FEM) to solve an equilibrium inside the fixed separatrix. In order to avoid difficulties of FEM (such as mesh problem, difficulty of coding, expensive calculation cost), this study focuses on the meshless methods, especially RBF-MFS and KANSA's method to solve the fixed boundary problem. The results showed that CPU time of the meshless methods was ten to one hundred times shorter than that of FEM to obtain the same accuracy.

Budget planning enables an organization to set priorities towards achieving certain goals and to identify the highest priorities to be accomplished with the available funds, thus allowing allocation of resources according to the set priorities and constraints. On the other hand, budget execution and monitoring enables allocated funds or resources to be utilized as planned. Our study concerns with investigating the relationship between budget allocation and budget utilization of faculties in a public university in Malaysia. The focus is on the university's operations management financial allocation and utilization based on five categories which are emolument expenditure, academic or services and supplies expenditure, maintenance expenditure, student expenditure and others expenditure. The analysis on financial allocation and utilization is performed based on yearly quarters. Data collected include three years faculties' budget allocation and budget utilization performance involving a sample of ten selected faculties of a public university in Malaysia. Results show that there are positive correlation and significant relationship between quarterly budget allocation and quarterly budget utilization. This study found that emolument give the highest contribution to the total allocation and total utilization for all quarters. This paper presents some findings based on statistical analysis conducted which include descriptive statistics and correlation analysis.

The moderation effect of personality on healthcare utilization in Chinese people living with HIV.

PubMed

Yu, Nancy Xiaonan; Mols, Floortje; Stewart, Sunita M; Zhang, Jianxin

2017-06-01

There is evidence that Type D personality can predict impaired quality of life and health status in various chronic conditions. The evidence is conflicting as to whether Type D is associated with increased healthcare services, and no study has reported on the healthcare utilization of people living with HIV (PLWH) who have a Type D personality. This study investigated the impact of Type D personality on healthcare utilization in a sample of Chinese PLWH and examined physical and emotional symptoms as possible mechanisms of healthcare utilization. This was a cross-sectional study of 199 PLWH in rural China. Participants completed a survey on physical symptoms, emotional symptoms, healthcare utilization, and Type D personality. Those PLWH with a Type D personality reported more physical and emotional symptoms and healthcare utilization than patients without this personality. Among PLWH who had a Type D personality, physical symptoms had a direct effect on healthcare utilization, and emotional symptoms did not significantly mediate this association. However, among PLWH without a Type D personality, emotional symptoms significantly mediated the effects of physical symptoms on healthcare utilization. PLWH with a Type D personality reported more healthcare utilization, which was attributed to their high physical symptoms rather than their emotional symptoms. These findings suggest that PLWH with a Type D personality might be bothered by intensified emotional symptoms, which might be too severe to be associated with physical symptoms and healthcare utilization. New prospective studies should focus on the pattern of healthcare utilization among patients with a Type D personality and their intensified physical and emotional symptoms.

Teach It, Don’t Preach It: The Differential Effects of Directly-communicated and Self-generated Utility Value Information

PubMed Central

Canning, Elizabeth A.; Harackiewicz, Judith M.

2015-01-01

Social-psychological interventions in education have used a variety of “self-persuasion” or “saying-is-believing” techniques to encourage students to articulate key intervention messages. These techniques are used in combination with more overt strategies, such as the direct communication of messages in order to promote attitude change. However, these different strategies have rarely been systematically compared, particularly in controlled laboratory settings. We focus on one intervention based in expectancy-value theory designed to promote perceptions of utility value in the classroom and test different intervention techniques to promote interest and performance. Across three laboratory studies, we used a mental math learning paradigm in which we varied whether students wrote about utility value for themselves or received different forms of directly-communicated information about the utility value of a novel mental math technique. In Study 1, we examined the difference between directly-communicated and self-generated utility-value information and found that directly-communicated utility-value information undermined performance and interest for individuals who lacked confidence, but that self-generated utility had positive effects. However, Study 2 suggests that these negative effects of directly-communicated utility value can be ameliorated when participants are also given the chance to generate their own examples of utility value, revealing a synergistic effect of directly-communicated and self-generated utility value. In Study 3, we found that individuals who lacked confidence benefited more when everyday examples of utility value were communicated, rather than career and school examples. PMID:26495326

Latino suicidal adolescent psychosocial service utilization: The role of mood fluctuations and inattention.

PubMed

Alonzo, Dana; Conway, Anne; Modrek, Anahid S

2016-01-15

Little is known about the specific factors related to whether or not Latino adolescents with suicide ideation (SI) will seek services. Utilizing Andersen's Behavior Model of Health Services Use (2008) the goal of this study is to identify the factors related to utilization of mental health services by Latino adolescents with SI to inform and improve suicide prevention efforts. Data from Wave 1 of the National Longitudinal Study of Adolescent Health was examined. Predispositional (gender, age), enabling/disabling (income, lack of insurance, difficulty obtaining medical care), and need (depressed mood, suicide attempt, perceived health, impulsivity, mood fluctuations, difficulties with attention, etc.) variables were examined via logistic regression as potential correlates of mental health service utilization. Twenty-eight percent of the Latino adolescents with suicidal ideation (SI) in our sample received mental health services. Need factors such as daily mood fluctuations within the past 12 months (OR=4.78) and frequent difficulty focusing attention within the past week (OR=4.96), but not impulsivity, were associated with an increased likelihood of receiving mental health services. No additional associations were observed. The current study is based on cross-sectional data. Therefore, statements about causality cannot be made. These findings suggest that emotion regulation (e.g., daily mood fluctuations) and neurocognitive factors (e.g., difficulty with focusing attention) may be important factors to consider in the clinical assessment of Latino adolescents with SI.

Kim, Han-Sung; Kim, Young-Hoon; Woo, Jung-Sik; Hyun, Sook-Jung

2015-01-01

Introduction Hospitals are studying the focused factory concept and attempting to increase their power in a competitive industry by becoming more specialized. Methodology This study uses the information theory index (ITI) and the Herfindahl-Hirschman index (HHI) to analyze the extent of specialization by Korean hospitals that receive national health insurance reimbursements. Hierarchical regression analysis is used to assess the impact of hospital specialization on the following four aspects of operational performance: productivity, profitability, efficiency and quality of care. Study Results The results show that a focused strategy (high HHI) improves the income and adjusted number of patients per specialist through the efficient utilization of human resources. However, a diversified strategy (high ITI) improves the hospital utilization ratio, income per bed and adjusted number of patients per bed (controlling for material resources such as beds). In addition, as the concentration index increases, case-mix mortality rates and referral rates decrease, indicating that specialization has a positive relationship with quality of care.

Labrague, L J; McEnroe-Petitte, D M; Al Amri, M; Fronda, D C; Obeidat, A A

2018-06-01

This study critically appraised both quantitative and qualitative studies describing coping strategies utilized by nursing students when faced with stress. Stress in nursing students during clinical training is well documented in the nursing literature. The need to utilize positive-coping strategies is necessary to effectively deal with stress and its accompanying stressors. An integrative review method was used in this review. PsycINFO, PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), MEDLINE and Scopus were the databases used in searching for relevant literature using the following search terms; 'coping', 'nursing students', clinical training', 'ways of coping' and 'clinical practice'. A total of 27 studies published from 2001 to 2016 were included in this review. Findings demonstrated that nursing students utilized problem-focused coping strategies rather than emotion-focused coping strategies. Specific coping behaviours utilized included problem-solving behaviours, self-confident approaches and seeking of support from family and friends. The review contributes to the growing literature on coping strategies in nursing students and may have implications on nursing education and nursing policy. This review also demonstrated a scarcity of studies that links specific coping strategies to nursing school stressors and examines predictors of coping skills in nursing students. Institutionalization of structured student orientation programme, implementation of well-planned mentoring programmes and establishment of support unit/centres may be helpful in supporting nursing students during their clinical placement. By developing empirically based interventions, nursing faculty can assist nursing students in strengthening their positive-coping skills to effectively deal with various stressors encountered. © 2017 International Council of Nurses.

Active surveillance (AS) is the most rapidly expanding management option for favorable-risk prostate cancer (PCa). Early studies suggested substantial decrements in utility (quality of life weights) from disease-related anxiety. Our objective was to determine utilities for contemporary AS patients using different instruments. We performed a systematic review of PubMed, PMC and OVID for utility measurements in modern AS patients. We then examined utilities among 37 men on AS participating in focus groups between 2015-2016 using the generic EurQol five dimensions questionnaire (EQ-5D-3L) and Patient Oriented Prostate Utility Scale (PORPUS), a PCa-specific instrument. The systematic review found previous studies with utilities for PCa treatment and historical watchful waiting populations, but none specifically in contemporary AS. In our AS population, the mean EQ-5D-3L score was 0.90±0.16 (median, 1.00; range, 0.21-1.00) and PORPUS was 0.98±0.03 (median, 0.99; range, 0.84-1.00). The Spearman correlation between the EQ-5D-3L and PORPUS was 0.87 (P<0.0001), and 38% of patients had a difference >0.1 between instruments. Most contemporary AS patients had high utility scores suggesting that they perceive themselves in good health without a major decrement in quality of life from the disease. However, some patients had substantial differences in utility measured with generic versus disease-specific instruments. Further study is warranted into the optimal instrument for utility assessment in contemporary AS patients.

The paper describes the efforts at NASA Langley to apply active and passive flow control techniques for improved high-lift systems, and advanced vehicle concepts utilizing powered high-lift techniques. The development of simplified high-lift systems utilizing active flow control is shown to provide significant weight and drag reduction benefits based on system studies. Active flow control that focuses on separation, and the development of advanced circulation control wings (CCW) utilizing unsteady excitation techniques will be discussed. The advanced CCW airfoils can provide multifunctional controls throughout the flight envelope. Computational and experimental data are shown to illustrate the benefits and issues with implementation of the technology.

This paper reviews youth outcomes following exposure to natural disaster, with a focus on three relatively understudied outcomes: externalizing behavior problems, physical health, and posttraumatic growth. Recent, high-impact studies focusing on each outcome are summarized. Studies highlighted in this review utilize innovative and comprehensive approaches to improve our current understanding of youth broad-based physical and mental health outcomes beyond PTSD. The review concludes with recommendations to advance the field of youth disaster research by exploring how disasters may impact children across multiple domains, as well as using cutting edge ecobiological approaches and advanced modeling strategies to better understand how youth adjust and thrive following natural disaster.

Poverty, wealth, and health care utilization: a geographic assessment.

Geographic variation has been of interest to both health planners and social epidemiologists. However, while the major focus of interest of planners has been on variation in health care spending, social epidemiologists have focused on health; and while social epidemiologists have observed strong associations between poor health and poverty, planners have concluded that income is not an important determinant of variation in spending. These different conclusions stem, at least in part, from differences in approach. Health planners have generally studied variation among large regions, such as states, counties, or hospital referral regions (HRRs), while epidemiologists have tended to study local areas, such as ZIP codes and census tracts. To better understand the basis for geographic variation in hospital utilization, we drew upon both approaches. Counties and HRRs were disaggregated into their constituent ZIP codes and census tracts and examined the interrelationships between income, disability, and hospital utilization that were examined at both the regional and local levels, using statistical and geomapping tools. Our studies centered on the Milwaukee and Los Angeles HRRs, where per capita health care utilization has been greater than elsewhere in their states. We compared Milwaukee to other HRRs in Wisconsin and Los Angeles to the other populous counties of California and to a region in California of comparable size and diversity, stretching from San Francisco to Sacramento (termed "San-Framento"). When studied at the ZIP code level, we found steep, curvilinear relationships between lower income and both increased hospital utilization and increasing percentages of individuals reporting disabilities. These associations were also evident on geomaps. They were strongest among populations of working-age adults but weaker among seniors, for whom income proved to be a poor proxy for poverty and whose residential locations deviated from the major underlying income patterns. Among working-age adults, virtually all of the excess utilization in Milwaukee was attributable to very high utilization in Milwaukee's segregated "poverty corridor." Similarly, the greater rate of hospital use in Los Angeles than in San-Framento could be explained by proportionately more low-income ZIP codes in Los Angeles and fewer in San-Framento. Indeed, when only high-income ZIP codes were assessed, there was little variation in hospital utilization among California's 18 most populous counties. We estimated that had utilization within each region been at the rate of its high-income ZIP codes, overall utilization would have been 35 % less among working-age adults and 20 % less among seniors. These studies reveal the importance of disaggregating large geographic units into their constituent ZIP codes in order to understand variation in health care utilization among them. They demonstrate the strong association between low ZIP code income and both higher percentages of disability and greater hospital utilization. And they suggest that, given the large contribution of the poorest neighborhoods to aggregate utilization, it will be difficult to curb the growth of health care spending without addressing the underlying social determinants of health.

Knowledge regarding compliance patterns and service utilization in e-health is important for the development of effective services. To develop proper e-health, the characteristics of compliance patterns and utilization of e-health should be studied. We studied these for glucose monitoring of diabetic patients from primary clinics. Data were collected from 160 outpatients who participated in e-health for glucose monitoring funded by the Korean government. Specifically, this study focused on two device types: a standalone Internet gateway and a tablet device. The SPSS 18.0 software was used for statistical analyses of demographic characteristics, survival data, and Cox proportional hazards regression model. Standalone Internet gateway users demonstrated a more stable compliance pattern than did tablet device users. The compliance rate differed according to the device type. Typically, compliance decreases considerably around 8 months. In these results, standalone Internet gateway users utilized the service for longer periods than tablet device users. Gateway type and location also influenced utilization (p < 0.05). The service should be designed according to the device type to develop appropriate service models. Thus, service designers should understand the different characteristics of service devices. This study provides insight into compliance patterns and utilization to develop appropriate service models and service interventions depending on the device.

Student use of Web 2.0 tools to support argumentation in a high school science classroom

NASA Astrophysics Data System (ADS)

Weible, Jennifer L.

This ethnographic study is an investigation into how two classes of chemistry students (n=35) from a low-income high school with a one-to-one laptop initiative used Web 2.0 tools to support participation in the science practice of argumentation (i.e., sensemaking, articulating understandings, and persuading an audience) during a unit on alternative energy. The science curriculum utilized the Technology-Enhanced Inquiry Tools for Science Education as a pedagogical framework (Kim, Hannafin, & Bryan, 2007). Video recordings of the classroom work, small group discussions, and focus group interviews, documents, screen shots, wiki evidence, and student produced multi-media artifacts were the data analyzed for this study. Open and focused coding techniques, counts of social tags and wiki moves, and interpretive analyses were used to find patterns in the data. The study found that the tools of social bookmarking, wiki, and persuasive multimedia artifacts supported participation in argumentation. In addition, students utilized the affordances of the technologies in multiple ways to communicate, collaborate, manage the work of others, and efficiently complete their science project. This study also found that technologically enhanced science curriculum can bridge students' everyday and scientific understandings of making meaning, articulating understandings, and persuading others of their point of view. As a result, implications from this work include a set of design principles for science inquiry learning that utilize technology. This study suggests new consideration of analytical methodology that blends wiki data analytics and video data. It also suggests that utilizing technology as a bridging strategy serves two roles within classrooms: (a) deepening students' understanding of alternative energy science content and (b) supporting students as they learn to participate in the practices of argumentation.

The Potential (F)utility of a Passive Organ Donor Registration Opportunity: A Conceptual Replication.

Approximately 22 people die each day in the United States as a result of the shortage of transplantable organs. This is particularly problematic among Spanish-dominant Hispanics. Increasing the number of registered organ donors can reduce this deficit. The goal of the current set of studies was to conceptually replicate a prior study indicating the lack of utility of a lone, immediate and complete registration opportunity (ICRO). The study, a quasi-experimental design involving a total of 4 waves of data collection, was conducted in 2 different Mexican consulates in the United States. Guided by the IIFF Model (ie, an ICRO, information, focused engagement, and favorable activation), each wave compared a lone ICRO to a condition that likewise included an ICRO but also included the 3 additional intervention components recommended by the model (ie, information, focused engagement, and favorable activation). Visitors to the Mexican consulates in Tucson, Arizona, and Albuquerque, New Mexico, constituted the participant pool. New organ donor registrations represented the dependent variable. When all 4 components of the IIFF Model were present, approximately 4 registrations per day were recorded; the lone ICRO resulted in approximately 1 registration every 15 days. An ICRO, without the other components of the IIFF Model, is of minimal use in regard to garnering organ donor registrations. Future studies should use the IIFF Model to consider how the utility of ICROs can be maximized. © 2016, NATCO.

To evaluate the utility of a teacher-rating instrument (Teacher Observation of Classroom Adaptation-Revised [TOCA-R]) of aggressive behavior during elementary school years in identifying girls at risk of later criminal court violence. A community epidemiological sample of 845 urban public school girls was rated at six time points during elementary school regarding their level of aggressive/disruptive behavior (75% of whom were African American). Criminal violence was measured using juvenile court records. Logistic regression was used to study the strength of the association between early indicators of aggressive behavior and adolescent females' violent outcomes. An extension of the traditional receiver operating characteristics analysis was used to study the accuracy of identifying girls at risk of violence under three different screening and intervention scenarios. For girls, teacher ratings of aggression were a strong and consistent predictor of later violence across grades 1-5 and were strongest in fifth grade. Three screening scenarios were compared to determine the optimal identification threshold. The screening scenario with a focus on minimizing false negatives yielded the highest value (kappa = 0.803). This study supports other studies indicating that early levels of aggressive behavior are strong and robust predictors of later violence among girls but are of limited utility in the early identification of girls at risk, especially when the focus is on reducing both false positives and negatives.

The objective of this research was to determine the effects of wellness programs on quality of life and utilization in an academic family medicine practice in two small controlled studies. One offered stress management and problem solving; the second offered a broader wellness intervention. Outcome measures consisted of scores on the Beck Anxiety Inventory, Hamilton Depression Inventory, CES-D (depression), Health Related Quality of Life, SF-12, and the number of office visits in 6 months. Subjects were randomly assigned to intervention or control groups. Statistical analysis compared pre-test and post-test values of the dependent variables between groups. In study one, where the focus was on relaxation, significant differences between groups were observed in anxiety at post-test (p < .03); the intervention group had lower anxiety levels. In study two which had a more general focus, significant group differences were found in days of poor mental health and number of days of depressed mood; the intervention group had fewer days of poor mental health (p < .05) and depression (p < .05) at post-test. No differences were found in utilization in either study. Based on the results of this research, short term wellness programs can be implemented in family practice and are effective in improving quality of life, but not in deceasing utilization in family practice patients. Matching the design of the program to specific patient needs may increase retention and effectiveness.

The objective of this study was to measure internal medicine resident engagement with an electronic medical record-based dashboard providing feedback on their use of routine laboratory tests relative to service averages. From January 2016 to June 2016, residents were e-mailed a snapshot of their personalized dashboard, a link to the online dashboard, and text summarizing the resident and service utilization averages. We measured resident engagement using e-mail read-receipts and web-based tracking. We also conducted 3 hour-long focus groups with residents. Using grounded theory approach, the transcripts were analyzed for common themes focusing on barriers and facilitators of dashboard use. Among 80 residents, 74% opened the e-mail containing a link to the dashboard and 21% accessed the dashboard itself. We did not observe a statistically significant difference in routine laboratory ordering by dashboard use, although residents who opened the link to the dashboard ordered 0.26 fewer labs per doctor-patient-day than those who did not (95% confidence interval, -0.77 to 0.25; = 0 .31). While they raised several concerns, focus group participants had positive attitudes toward receiving individualized feedback delivered in real time. © 2017 Society of Hospital Medicine.

A novel algorithm for fast and efficient multifocus wavefront shaping

NASA Astrophysics Data System (ADS)

Fayyaz, Zahra; Nasiriavanaki, Mohammadreza

2018-02-01

Wavefront shaping using spatial light modulator (SLM) is a popular method for focusing light through a turbid media, such as biological tissues. Usually, in iterative optimization methods, due to the very large number of pixels in SLM, larger pixels are formed, bins, and the phase value of the bins are changed to obtain an optimum phase map, hence a focus. In this study an efficient optimization algorithm is proposed to obtain an arbitrary map of focus utilizing all the SLM pixels or small bin sizes. The application of such methodology in dermatology, hair removal in particular, is explored and discussed

Does performance evaluation help public managers? A Balanced Scorecard approach in urban waste services.

PubMed

Guimarães, Bernardo; Simões, Pedro; Marques, Rui Cunha

2010-12-01

The urban waste market has evolved significantly in the past decades, which among other changes, has led to the creation of new utilities and new business models. However, very few things have changed for the users. Urban waste collection remains mainly under the responsibility of local authorities and the charges paid by the users in most countries are very low compared to the provision costs. This situation forces the injection of public money into the system, encouraging the 'quiet-life' within the utilities and, therefore, inefficiency. The present study intends to analyze the potential for the application of the Balanced Scorecard (BSc) methodology into the waste utilities. After a comprehensive revision of the urban waste sector in Portugal, the methodology of BSc and its application in local public services is described and discussed. Focusing on implementation rather than on strategy, a set of performance indicators is proposed to be utilized in the different management models of waste utilities in Portugal: the municipalities, semi-autonomous utilities, municipal companies and mixed companies. This implementation is then exemplified through four case studies, one for each type of utility. This paper provides a flexible framework proposal to be applied to waste utilities operating both in Portugal and abroad. Copyright © 2010 Elsevier Ltd. All rights reserved.

Mental Health Services for Children and Youth in the Child Welfare System: A Focus on Caregivers as Gatekeepers.

Villagrana, Margarita

2010-05-01

Caregivers serve as gatekeepers for children while in the child welfare system, but few studies have focused on the caregiver and the factors that influence the use of mental health services for the children under their care. The purpose of this study was to examine the child's mental health need, the caregiver's level of stress, depression, and social support, and the utilization of mental health services by children using the three most common types of caregivers in the child welfare system (i.e., birth parent, relative caregiver, and foster parent). Data comes from the Patterns of Care (POC) study of five public sectors of care. The present study examined parents/caregivers and youth from the child welfare sector. Findings suggest that while birth parents were more likely to endorse more risk factors for themselves, and the children under their care had a higher level of mental health need, they were the least likely to utilize mental health services for the children under their care. Implications for the child welfare and mental health systems are discussed.

Application of Regulatory Focus Theory to Search Advertising.

PubMed

Mowle, Elyse N; Georgia, Emily J; Doss, Brian D; Updegraff, John A

The purpose of this paper is to test the utility of regulatory focus theory principles in a real-world setting; specifically, Internet hosted text advertisements. Effect of compatibility of the ad text with the regulatory focus of the consumer was examined. Advertisements were created using Google AdWords. Data were collected for the number of views and clicks each ad received. Effect of regulatory fit was measured using logistic regression. Logistic regression analyses demonstrated that there was a strong main effect for keyword, such that users were almost six times as likely to click on a promotion advertisement as a prevention advertisement, as well as a main effect for compatibility, such that users were twice as likely to click on an advertisement with content that was consistent with their keyword. Finally, there was a strong interaction of these two variables, such that the effect of consistent advertisements was stronger for promotion searches than for prevention searches. The effect of ad compatibility had medium to large effect sizes, suggesting that individuals' state may have more influence on advertising response than do individuals' traits (e.g. personality traits). Measurement of regulatory fit was limited by the constraints of Google AdWords. The results of this study provide a possible framework for ad creation for Internet advertisers. This paper is the first study to demonstrate the utility of regulatory focus theory in online advertising.

Conceptualizing race in economic models of medical utilization: a case study of community-based elders and the emergency room.

PubMed Central

White-Means, S I

1995-01-01

There is no consensus on the appropriate conceptualization of race in economic models of health care. This is because race is rarely the primary focus for analysis of the market. This article presents an alternative framework for conceptualizing race in health economic models. A case study is analyzed to illustrate the value of the alternative conceptualization. The case study findings clearly document the importance of model stratification according to race. Moreover, the findings indicate that empirical results are improved when medical utilization models are refined in a way that reflects the unique experiences of the population that is studied.

Characteristics of utility cyclists in Queensland, Australia: an examination of the associations between individual, social, and environmental factors and utility cycling.

PubMed

Sahlqvist, Shannon L; Heesch, Kristiann C

2012-08-01

Initiatives to promote utility cycling in countries like Australia and the US, which have low rates of utility cycling, may be more effective if they first target recreational cyclists. This study aimed to describe patterns of utility cycling and examine its correlates, among cyclists in Queensland, Australia. An online survey was administered to adult members of a state-based cycling community and advocacy group (n=1813). The survey asked about demographic characteristics and cycling behavior, motivators and constraints. Utility cycling patterns were described, and logistic regression modeling was used to examine associations between utility cycling and other variables. Forty-seven percent of respondents reported utility cycling: most did so to commute (86%). Most journeys (83%) were >5 km. Being male, younger, employed full-time, or university-educated increased the likelihood of utility cycling (P<.05). Perceiving cycling to be a cheap or a convenient form of transport was associated with utility cycling (P<.05). The moderate rate of utility cycling among recreational cyclists highlights a potential to promote utility cycling among this group. To increase utility cycling, strategies should target female and older recreational cyclists and focus on making cycling a cheap and convenient mode of transport.

Mohan, Sumitra; Chemi, Francesca

2017-01-01

Since blood borne circulating tumour cells (CTCs) initially shed from the primary tumour can seed and initiate metastasis at distant sites a better understanding of the biology of CTCs and their dissemination could provide valuable information that could guide therapeutic intervention and real time monitoring of disease progression. Although CTC enumeration has provided a reliable prognostic readout for a number of cancers, including lung cancer, the precise clinical utility of CTCs remains to be established. The rarity of CTCs together with the vanishingly small amounts of nucleic acids present in a single cell as well as cell to cell heterogeneity has stimulated the development of a wide range of powerful cellular and molecular methodologies applied to CTCs. These technical developments are now enabling researchers to focus on understanding the biology of CTCs and their clinical utility as a predictive and pharmacodynamics markers. This review summarises recent advances in the field of CTC research with focus on technical and biological challenges as well the progress made towards clinical utility of characterisation of CTCs with emphasis on studies in lung cancer.

We theoretically study the dynamics of ferrimagnetic skyrmions in inhomogeneous metallic films close to the angular momentum compensation point. In particular, it is shown that the line of the vanishing angular momentum can be utilized as a self-focusing racetrack for skyrmions. To that end, we begin by deriving the equations of motion for the dynamics of collinear ferrimagnets in the presence of a charge current. The obtained equations of motion reduce to those of ferromagnets and antiferromagnets at two special limits. In the collective coordinate approach, a skyrmion behaves as a massive charged particle moving in a viscous medium subjected to a magnetic field. Analogous to the snake orbits of electrons in a nonuniform magnetic field, we show that a ferrimagnet with nonuniform angular momentum density can exhibit the snake trajectories of skyrmions, which can be utilized as racetracks for skyrmions.

Examining the Personal Nature of the K-14 Engineering Pipeline for Young Women

NASA Astrophysics Data System (ADS)

Gurski, Jennifer Sue

This mixed-methods study examined young women's perceptions of their K-14 STEM pipeline experiences and their resulting choice to enter and persist in an engineering major. Despite the increase of women in the STEM workforce, women remain underrepresented among engineering majors (Beasley & Fischer, 2012; Heilbronner, 2012; Neihart & Teo, 2013). Few studies exist that utilize a retrospective approach to understand how the culmination of young women's K-14 experiences have influenced their formation of individually held perceptions that lead to engineering persistence. It is this study's aim to utilize a mixed-methods approach to answer the following research question: How do young women's perceptions of their K-14 STEM experiences influence their decision to enroll and persist in an engineering major? These perceptions are explored through an ethnographic approach focusing on young women enrolled in engineering programs during their junior and senior years of study at a small private liberal arts university with eight engineering majors. The mixed-methods approach follows a sequential design method (Creswell, 2013) and utilizes questions in a quantitative Likert-type survey from the Academic Pathways for People Learning Engineering (APPLES) survey (Eris, Chachra, Chen, Sheppard, & Ludlow, 2010) and the Motivated Strategy Learning Questionnaire (MSLQ) (Pintrich, Smith, Garcia, & McKeachie, 1991). The quantitative study results will lead to the development of open-ended, structured questions for conducting a qualitative focus group. Anonymity of all participants is maintained. Keywords: STEM, young women, perceptions, pipeline, intervention, underrepresentation, engineering, persistence, retrospective, self-efficacy.

Commercial and Multifamily Building Tenant Energy Usage Aggregation and Privacy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Livingston, Olga V.; Pulsipher, Trenton C.; Wang, Na

2014-11-17

In a number of cities and states, building owners are required to disclose and/or benchmark their building energy use. This requires the building owner to possess monthly whole-building energy usage information, which can be challenging for buildings in which individual tenants have their own utility meters and accounts with the utility. Some utilities and utility regulators have turned to aggregation of customer data as a way to give building owners the whole-building energy usage data while protecting customer privacy. However, no utilities or regulators appear to have conducted a concerted statistical, cybersecurity, and privacy analysis to justify the level ofmore » aggregation selected. Therefore, the Tennant Data Aggregation Task was established to help utilities address these issues and provide recommendations as well as a theoretical justification of the aggregation threshold. This study is focused on the use case of submitting data for ENERGY STAR Portfolio Manager (ESPM), but it also looks at other potential use cases for monthly energy consumption data.« less

Can Faith and Hospice Coexist: Is the African American Church the Key to Increased Hospice Utilization for African Americans?

PubMed

Townsend, Apollo; March, Alice L; Kimball, Jan

2017-01-01

African Americans are twice as likely as Caucasian Americans to choose aggressive hospital treatment when death is imminent. Repeat hospitalizations are traumatic for patients and drain patient and health system resources. Hospice care is a specialized alternative that vastly improves patient quality of life at end-of-life. This study was conducted to determine if hospices partnering with African American churches to disseminate hospice education materials could increase utilization of hospice services by African Americans. Members of two African American churches (N = 34) participated in focus group discussions to elicit beliefs about hospice care. Focus group transcripts were coded and comments were grouped according to theme. Six themes were identified. Lack of knowledge about hospice services and spiritual beliefs emerged as the top two contributing factors for underutilization of hospice services. Study findings support partnerships between hospices and African American churches to provide hospice education to the African American community. © The Author(s) 2015.

Hospitals are studying the focused factory concept and attempting to increase their power in a competitive industry by becoming more specialized. This study uses the information theory index (ITI) and the Herfindahl-Hirschman index (HHI) to analyze the extent of specialization by Korean hospitals that receive national health insurance reimbursements. Hierarchical regression analysis is used to assess the impact of hospital specialization on the following four aspects of operational performance: productivity, profitability, efficiency and quality of care. The results show that a focused strategy (high HHI) improves the income and adjusted number of patients per specialist through the efficient utilization of human resources. However, a diversified strategy (high ITI) improves the hospital utilization ratio, income per bed and adjusted number of patients per bed (controlling for material resources such as beds). In addition, as the concentration index increases, case-mix mortality rates and referral rates decrease, indicating that specialization has a positive relationship with quality of care.

School psychology recruitment research characteristics and implications for increasing racial and ethnic diversity.

Proctor, Sherrie L; Romano, Maria

2016-09-01

Shortages of school psychologists and the underrepresentation of minorities in school psychology represent longstanding concerns. Scholars recommend that one way to address both issues is to recruit individuals from racially and ethnically diverse backgrounds into school psychology. The purpose of this study was to explore the characteristics and minority focused findings of school psychology recruitment studies conducted from 1994 to 2014. Using an electronic search that included specified databases, subject terms and study inclusion criteria along with a manual search of 10 school psychology focused journals, the review yielded 10 published, peer-reviewed recruitment studies focused primarily on school psychology over the 20-year span. Two researchers coded these 10 studies using a rigorous coding process that included a high level of inter rater reliability. Results suggest that the studies utilized varied methodologies, primarily sampled undergraduate populations, and mostly included White participants. Five studies focused on minority populations specifically. These studies indicate that programs should actively recruit minority undergraduates and offer financial support to attract minority candidates. Implications suggest a need for more recruitment research focused on minority populations and the implementation and evaluation of minority recruitment models.

Ecologically-focused Calibration of Hydrological Models for Environmental Flow Applications

NASA Astrophysics Data System (ADS)

Adams, S. K.; Bledsoe, B. P.

2015-12-01

Hydrologic alteration resulting from watershed urbanization is a common cause of aquatic ecosystem degradation. Developing environmental flow criteria for urbanizing watersheds requires quantitative flow-ecology relationships that describe biological responses to streamflow alteration. Ideally, gaged flow data are used to develop flow-ecology relationships; however, biological monitoring sites are frequently ungaged. For these ungaged locations, hydrologic models must be used to predict streamflow characteristics through calibration and testing at gaged sites, followed by extrapolation to ungaged sites. Physically-based modeling of rainfall-runoff response has frequently utilized "best overall fit" calibration criteria, such as the Nash-Sutcliffe Efficiency (NSE), that do not necessarily focus on specific aspects of the flow regime relevant to biota of interest. This study investigates the utility of employing flow characteristics known a priori to influence regional biological endpoints as "ecologically-focused" calibration criteria compared to traditional, "best overall fit" criteria. For this study, 19 continuous HEC-HMS 4.0 models were created in coastal southern California and calibrated to hourly USGS streamflow gages with nearby biological monitoring sites using one "best overall fit" and three "ecologically-focused" criteria: NSE, Richards-Baker Flashiness Index (RBI), percent of time when the flow is < 1 cfs (%<1), and a Combined Calibration (RBI and %<1). Calibrated models were compared using calibration accuracy, environmental flow metric reproducibility, and the strength of flow-ecology relationships. Results indicate that "ecologically-focused" criteria can be calibrated with high accuracy and may provide stronger flow-ecology relationships than "best overall fit" criteria, especially when multiple "ecologically-focused" criteria are used in concert, despite inabilities to accurately reproduce additional types of ecological flow metrics to which the models are not explicitly calibrated.

2008-07-01

We study the evolution of resource utilization in a structured discrete-time metapopulation model with an infinite number of patches, prone to local catastrophes. The consumer faces a trade-off in the abilities to consume two resources available in different amounts in each patch. We analyse how the evolution of specialization in the utilization of the resources is affected by different ecological factors: migration, local growth, local catastrophes, forms of the trade-off and distribution of the resources in the patches. Our modelling approach offers a natural way to include more than two patch types into the models. This has not been usually possible in the previous spatially heterogeneous models focusing on the evolution of specialization.

Many countries are developing health financing mechanisms to pursue the goal of universal coverage. In China, a rural health insurance system entitled New Cooperative Medical Scheme (NCMS) is being developed since 2003. Although there is concern about whether the NCMS will influence the serious situation of inequity in health service utilization in rural China, there is only limited evidence available. This paper aims to assess the utilisation of outpatient and inpatient services among different income groups and provinces under NCMS in rural China. Using multistage sampling processes, a cross-sectional household survey including 6,147 rural households and 22,636 individuals, was conducted in six counties in Shandong and Ningxia Provinces, China. Chi-square test, Poisson regression and log-linear regression were applied to analyze the association between NCMS and the utilization of outpatient and inpatient services and the length of stay for inpatients. Qualitative methods including individual interview and focus group discussion were applied to explain and complement the findings from the household survey. NCMS coverage was 95.9% in Shandong and 88.0% in Ningxia in 2006. NCMS membership had no significant association with outpatient service utilization regardless of income level and location.Inpatient service utilization has increased for the high income group under NCMS, but for the middle and low income, the change was not significant. Compared with non-members, NCMS members from Ningxia used inpatient services more frequently, while members from Shandong had a longer stay in hospital.High medical expenditure, low reimbursement rate and difference in NCMS policy design between regions were identified as the main reasons for the differences in health service utilization. Outpatient service utilization has not significantly changed under NCMS. Although utilization of inpatient service in general has increased under NCMS, people with high income tend to benefit more than the low income group. While providing financial protection against catastrophic medical expenditure is the principal focus of NCMS, this study recommends that outpatient services should be incorporated in future NCMS policy development. NCMS policy should also be more equity oriented to achieve its policy goal.

OSSA Space Station Freedom science utilization plans

Cressy, Philip J.

Long duration exposure to an essentially zero-gravity environment is a phenomenon exclusive to the Space Station Freedom that cannot be duplicated on Earth. The Freedom Station will offer periods of time on orbit extending to weeks and months rather than hours or days, allowing for in-depth space based research and analysis to a degree never before achieved. OSSA remains committed to exploiting the unique capabilities provided by the Space Station as well as other space-based facilities to study the nature of physical, chemical, and biological processes in a low-gravity environment and to apply these studies to advance science and applications in such fields as biomedical research, plant and animal physiology, exobiology, biotechnology, materials science, fluid physics, and combustion science. The OSSA focus is on progressive science investigations, many requiring hands-on scientist involvement using sophisticated experiment hardware. OSSA science utilization planning for the Freedom Station is firmly established. For this presentation, this planning is discussed in three general areas: OSSA goals and overall approach, the current and on-going program, and plans for space station utilization. In the first area, OSSA addresses its overall approach to space science research, its commitment to transition to Space Station Freedom, and its top-level strategy for the utilization of Freedom. The current and on-going program is next discussed, focusing on the various Spacelab series of missions which are providing the stepping-stones to Space Station Freedom. Selected science results from SLS-1 and USML-1 are cited which underline the value of properly outfitted laboratories in space in which crew-intensive experiment interactions are possible. The presentation is concluded with a discussion of top-level goals and strategies for utilizing the Freedom Station by OSSA's Life Sciences Division and its Microgravity Science and Applications Division.

States of Cybersecurity: Electricity Distribution System Discussions

Pena, Ivonne; Ingram, Michael; Martin, Maurice

State and local entities that oversee the reliable, affordable provision of electricity are faced with growing and evolving threats from cybersecurity risks to our nation's electricity distribution system. All-hazards system resilience is a shared responsibility among electric utilities and their regulators or policy-setting boards of directors. Cybersecurity presents new challenges and should be a focus for states, local governments, and Native American tribes that are developing energy-assurance plans to protect critical infrastructure. This research sought to investigate the implementation of governance and policy at the distribution utility level that facilitates cybersecurity preparedness to inform the U.S. Department of Energy (DOE),more » Office of Energy Policy and Systems Analysis; states; local governments; and other stakeholders on the challenges, gaps, and opportunities that may exist for future analysis. The need is urgent to identify the challenges and inconsistencies in how cybersecurity practices are being applied across the United States to inform the development of best practices, mitigations, and future research and development investments in securing the electricity infrastructure. By examining the current practices and applications of cybersecurity preparedness, this report seeks to identify the challenges and persistent gaps between policy and execution and reflect the underlying motivations of distinct utility structures as they play out at the local level. This study aims to create an initial baseline of cybersecurity preparedness within the distribution electricity sector. The focus of this study is on distribution utilities not bound by the cybersecurity guidelines of the North American Electric Reliability Corporation (NERC) to examine the range of mechanisms taken by state regulators, city councils that own municipal utilities, and boards of directors of rural cooperatives.« less

2016-10-01

Evidence supports validity of the Personal Care Participation Assessment and Resource Tool (PC-PART), but clinical utility remains unverified. This study aimed to investigate occupational therapists' perceptions about the PC-PART's clinical utility for inpatient rehabilitation. Using mixed methods, occupational therapists who had used the PC-PART as part of a research study in an inpatient rehabilitation setting completed a questionnaire ( n = 9) and participated in a focus group ( n = 6) to explore their perspectives about its clinical utility. Quantitative data were summarized and qualitative data analyzed using inductive thematic analysis. Quantitative data highlighted both positive and negative aspects of the PC-PART's clinical utility. Five themes emerged from the qualitative data: nature of information gathered; familiarity with the instrument; perceived time and effort; item phrasing, interpretation, and presentation; and external influences on clinical use. The PC-PART was perceived to support gathering of clinically useful information, helpful to intervention and discharge planning. Recommendations for improving some item phrasing, operational definitions, and instructions were identified. Although standardized assessments were valued, use in routine practice was challenging, requiring a knowledge translation strategy.

The objective was to explore progress of equity in the utilization of maternal health care services in developing countries since maternal care is a crucial factor in reducing maternal mortality, which is targeted by the Millennium Development Goal 5. A systematic review of quantitative studies was done. PubMed Central, Web of Science, and Science Direct databases were searched for peer-reviewed and English-language articles published between 2005 and 2015. Thirty-six articles were included in the review. The results reveal the lack of equity in the utilization of maternal health care in developing countries. Thirty-three out of 36 studies found evidence supporting severe inequities while three studies found evidence of equity or at least improvement in terms of equity. Most of the literature devoted to utilization of maternal health care generally provides information on the level of maternal care used and ignore the equity problem. Research in this area should focus not only on the level of maternal care used but also on the most disadvantaged segments of the population in terms of utilization of maternal care in order to reach the set targets.

Placental tissues are frequently utilized by scientists studying pregnancy and reproduction and in diverse fields including immunology, stem cell research, genetics, cancer research, and tissue engineering, as well as by clinicians in many therapies. Though the utilization of the human placenta in science and medicine has benefitted many people, little is known about public perspectives of this phenomenon. This review addresses placental donation, collection, and utilization in science and medicine, focusing on public perspectives. Cultural values and traditions, ethical paradigms and concerns, public understandings of science and medicine, and political considerations may impact perceptions of the utilization of the placenta in science and medicine, but systematic study is lacking. It is argued that knowledge of public views gained from empirical investigation may underpin the development of collection protocols and research projects that are more responsive to public will, spur more extensive utilization in science and medicine of this unique organ, and/or aid in the realization of the mobilization of knowledge about the placenta for clinical and educational ends. New avenues for research on public perspectives of the placenta are proposed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Exploring Geographic Variation of Mental Health Risk and Service Utilization of Doctors and Hospitals in Toronto: A Shared Component Spatial Modeling Approach

PubMed Central

Perlman, Christopher

2018-01-01

Mental Health has been known to vary geographically. Different rates of utilization of mental health services in local areas reflect geographic variation of mental health and complexity of health care. Variations and inequalities in how the health care system addresses risks are two critical issues for addressing population mental health. This study examines these issues by analyzing the utilization of mental health services in Toronto at the neighbourhood level. We adopted a shared component spatial modeling approach that allows simultaneous analysis of two main health service utilizations: doctor visits and hospitalizations related to mental health conditions. Our results reflect a geographic variation of both types of mental health service utilization across neighbourhoods in Toronto. We identified hot and cold spots of mental health risks that are common to both or specific to only one type of health service utilization. Based on the evidence found, we discuss intervention strategies, focusing on the hotspots and provision of health services about doctors and hospitals, to improve mental health for the neighbourhoods. Limitations of the study and further research directions are also discussed. PMID:29587426

2017-04-01

This study utilizes Terror Management Theory (TMT) to examine differences between eliciting social death and physical death anxiety related to smoking, smoking attitudes, and quitting intent among college students. Moreover, an important TMT variable-self-esteem-was used as a moderator. A 2 × 3 between-subjects factorial design crossed smoking-based self-esteem (low, high) with mortality salience manipulation (health-focused, social-focused, control). Results suggest while both making health-focused salient and making social-focused mortality salient were effective at getting smokers to quit, there was less effect for health-focused mortality salience on those whose self-esteem is strongly tied to smoking. Effect of social-focused mortality salience was more pronounced among participants who highly linked self-esteem with smoking. For smokers with low smoking-based self-esteem, both health-focused and social-focused mortality salience were effective at motivating attitude change toward smoking and quitting intentions. Implications for smoking cessation ad design and TMT are discussed.

Utilization of timber and bamboo as building materials was very promising for now and future. As renewable resources they have high mechanical properties, lightweight, environmentally friendly and economic. Utilization of bamboo as connector was rarely published. Therefore, this study focused on utilization of non-metal material as connector in timber structure especially for beam and column. This research was conducted in the laboratory to examine the strength of double shear timber connection by using glued in rods (bamboo dowel) as connector with variation of adhesive thickness. As control specimen was used bamboo dowel Ø14 mm without adhesive in double shear connection. The results showed that the strength of double shear timber connection by using glued in rods (bamboo dowel) as connector could increased by 41% to resist axial force higher than the control one.

1984-01-01

The urban growth of Brasilia within the last ten years is analyzed with special emphasis on the utilization of remote sensing orbital data and automatic image processing. The urban spatial structure and the monitoring of its temporal changes were focused in a whole and dynamic way by the utilization of MSS-LANDSAT images for June 1973, 1978 and 1983. In order to aid data interpretation, a registration algorithm implemented at the Interactive Multispectral Image Analysis System (IMAGE-100) was utilized aiming at the overlap of multitemporal images. The utilization of suitable digital filters, combined with the images overlap, allowed a rapid identification of areas of possible urban growth and oriented the field work. The results obtained permitted an evaluation of the urban growth of Brasilia, taking as reference the proposed stated for the construction of the city.

Real-time optimized biofeedback utilizing sport techniques (ROBUST): a study protocol for a randomized controlled trial.

2017-02-07

Anterior cruciate ligament (ACL) injuries in female athletes lead to a variety of short- and long-term physical, financial, and psychosocial ramifications. While dedicated injury prevention training programs have shown promise, ACL injury rates remain high as implementation has not become widespread. Conventional prevention programs use a combination of resistance, plyometric, balance and agility training to improve high-risk biomechanics and reduce the risk of injury. While many of these programs focus on reducing knee abduction load and posture during dynamic activity, targeting hip extensor strength and utilization may be more efficacious, as it is theorized to be an underlying mechanism of injury in adolescent female athletes. Biofeedback training may complement traditional preventive training, but has not been widely studied in connection with ACL injuries. We hypothesize that biofeedback may be needed to maximize the effectiveness of neuromuscular prophylactic interventions, and that hip-focused biofeedback will improve lower extremity biomechanics to a larger extent than knee-focused biofeedback during dynamic sport-specific tasks and long-term movement strategies. This is an assessor-blind, randomized control trial of 150 adolescent competitive female (9-19 years) soccer players. Each participant receives 3x/week neuromuscular preventive training and 1x/week biofeedback, the mode depending on their randomization to one of 3 biofeedback groups (hip-focused, knee-focused, sham). The primary aim is to assess the impact of biofeedback training on knee abduction moments (the primary biomechanical predictor of future ACL injury) during double-leg landings, single-leg landings, and unplanned cutting. Testing will occur immediately before the training intervention, immediately after the training intervention, and 6 months after the training intervention to assess the long-term retention of modified biomechanics. Secondary aims will assess performance changes, including hip and core strength, power, and agility, and the extent to which maturation effects biofeedback efficacy. The results of the Real-time Optimized Biofeedback Utilizing Sport Techniques (ROBUST) trial will help complement current preventive training and may lead to clinician-friendly methods of biofeedback to incorporate into widespread training practices.

Meteoritics research is a major beneficiary of recent developments in analytical instrumentation [1,2]. Integrated studies in which multiple analytical techniques are applied to the same specimen are providing new insight about the nature of IDPs [1]. Such studies are dependent on the ability to prepare specimens that can be analyzed in multiple instruments. Focused ion beam (FIB) microscopy has revolutionized specimen preparation in materials science [3]. Although FIB has successfully been used for a few IDP and meteorite studies [1,4-6], it has yet to be widely utilized in meteoritics. We are using FIB for integrated TEM/NanoSIMS/synchrotron infrared (IR) studies [1].

Development of a Portfolio Management Approach with Case Study of the NASA Airspace Systems Program

NASA Technical Reports Server (NTRS)

Neitzke, Kurt W.; Hartman, Christopher L.

2012-01-01

A portfolio management approach was developed for the National Aeronautics and Space Administration s (NASA s) Airspace Systems Program (ASP). The purpose was to help inform ASP leadership regarding future investment decisions related to its existing portfolio of advanced technology concepts and capabilities (C/Cs) currently under development and to potentially identify new opportunities. The portfolio management approach is general in form and is extensible to other advanced technology development programs. It focuses on individual C/Cs and consists of three parts: 1) concept of operations (con-ops) development, 2) safety impact assessment, and 3) benefit-cost-risk (B-C-R) assessment. The first two parts are recommendations to ASP leaders and will be discussed only briefly, while the B-C-R part relates to the development of an assessment capability and will be discussed in greater detail. The B-C-R assessment capability enables estimation of the relative value of each C/C as compared with all other C/Cs in the ASP portfolio. Value is expressed in terms of a composite weighted utility function (WUF) rating, based on estimated benefits, costs, and risks. Benefit utility is estimated relative to achieving key NAS performance objectives, which are outlined in the ASP Strategic Plan.1 Risk utility focuses on C/C development and implementation risk, while cost utility focuses on the development and implementation portions of overall C/C life-cycle costs. Initial composite ratings of the ASP C/Cs were successfully generated; however, the limited availability of B-C-R information, which is used as inputs to the WUF model, reduced the meaningfulness of these initial investment ratings. Development of this approach, however, defined specific information-generation requirements for ASP C/C developers that will increase the meaningfulness of future B-C-R ratings.

2018-04-01

Human papillomavirus (HPV)-related morbidity and mortality remain a significant public health burden despite the availability of HPV vaccines for cancer prevention. We engaged clinicians and parents to identify barriers and opportunities related to adolescent HPV vaccination within a focused geographic region. This mixed-method study design used an interviewer-administered semi-structured interview with clinicians (n = 52) and a written self-administered survey with similar items completed by parents (n = 54). Items focused on experiences, opinions, and ideas about HPV vaccine utilization in the clinical setting, family, and patient perceptions about HPV vaccination and potential future efforts to increase vaccine utilization. Quantitative items were analyzed using descriptive statistics, while qualitative content was analyzed thematically. Suggested solutions for achieving higher rates of HPV vaccination noted by clinicians included public health education, the removal of stigma associated with vaccines, media endorsements, and targeting parents as the primary focus of educational messages. Parents expressed the need for more information about HPV-related disease, HPV vaccines, vaccine safety, sexual concerns, and countering misinformation on social media. Results from this mixed-method study affirm that educational campaigns targeting both health care professionals and parents represent a key facilitator for promoting HPV vaccination; disease burden and cancer prevention emerged as key themes for this messaging.

2016-10-01

Simulation models are widely used in risk analysis to study the effects of uncertainties on outcomes of interest in complex problems. Often, these models are computationally complex and time consuming to run. This latter point may be at odds with time-sensitive evaluations or may limit the number of parameters that are considered. In this article, we give an introductory tutorial focused on parallelizing simulation code to better leverage modern computing hardware, enabling risk analysts to better utilize simulation-based methods for quantifying uncertainty in practice. This article is aimed primarily at risk analysts who use simulation methods but do not yet utilize parallelization to decrease the computational burden of these models. The discussion is focused on conceptual aspects of embarrassingly parallel computer code and software considerations. Two complementary examples are shown using the languages MATLAB and R. A brief discussion of hardware considerations is located in the Appendix. © 2016 Society for Risk Analysis.

Area-Specific Marginal Costing for Electric Utilities: a Case Study of Transmission and Distribution Costs

NASA Astrophysics Data System (ADS)

Orans, Ren

1990-10-01

Existing procedures used to develop marginal costs for electric utilities were not designed for applications in an increasingly competitive market for electric power. The utility's value of receiving power, or the costs of selling power, however, depend on the exact location of the buyer or seller, the magnitude of the power and the period of time over which the power is used. Yet no electric utility in the United States has disaggregate marginal costs that reflect differences in costs due to the time, size or location of the load associated with their power or energy transactions. The existing marginal costing methods used by electric utilities were developed in response to the Public Utilities Regulatory Policy Act (PURPA) in 1978. The "ratemaking standards" (Title 1) established by PURPA were primarily concerned with the appropriate segmentation of total revenues to various classes-of-service, designing time-of-use rating periods, and the promotion of efficient long-term resource planning. By design, the methods were very simple and inexpensive to implement. Now, more than a decade later, the costing issues facing electric utilities are becoming increasingly complex, and the benefits of developing more specific marginal costs will outweigh the costs of developing this information in many cases. This research develops a framework for estimating total marginal costs that vary by the size, timing, and the location of changes in loads within an electric distribution system. To complement the existing work at the Electric Power Research Institute (EPRI) and Pacific Gas and Electric Company (PGandE) on estimating disaggregate generation and transmission capacity costs, this dissertation focuses on the estimation of distribution capacity costs. While the costing procedure is suitable for the estimation of total (generation, transmission and distribution) marginal costs, the empirical work focuses on the geographic disaggregation of marginal costs related to electric utility distribution investment. The study makes use of data from an actual distribution planning area, located within PGandE's service territory, to demonstrate the important characteristics of this new costing approach. The most significant result of this empirical work is that geographic differences in the cost of capacity in distribution systems can be as much as four times larger than the current system average utility estimates. Furthermore, lumpy capital investment patterns can lead to significant cost differences over time.

Fourteen initial focus group discussions on Sprinkles and a 25-family home study were conducted. For the home study, each child 6 to 59 months of age in the household received 30 sachets (1 per day). The initial 14 focus group discussions included mothers, grandmothers, vendors, women who purchased from vendors, and adults in the general population. Home study families were recruited from participants in the initial 14 focus group discussions who had at least one child 6 to 59 months of age. Sprinkles were highly acceptable to adults and most children; some children thought Sprinkles were sugar. Most home study families prepared and used Sprinkles correctly. All families reported positive effects, particularly increased appetite, and recommended Sprinkles; none experienced major problems. Potential barriers identified were lack of knowledge of and experience with Sprinkles, availability of Sprinkles, and cost. Promotional messages targeted to mothers, fathers, all child-care providers, and doctors focused on the positive health effects of Sprinkles. Issues related to Sprinkles preparation, use, and barriers required attention before implementation. Locally appropriate visual and written instructions were developed for dissemination. Intervention training sessions and promotions were tailored to answer frequently asked questions, increase knowledge of Sprinkles, and provide tangible evidence of health benefits. Information needs and perceptions changed quickly after use of Sprinkles. Existing levels of Sprinkles awareness and knowledge should be considered when designing interventions.

Purpose The purpose of this paper is to test the utility of regulatory focus theory principles in a real-world setting; specifically, Internet hosted text advertisements. Effect of compatibility of the ad text with the regulatory focus of the consumer was examined. Design/methodology/approach Advertisements were created using Google AdWords. Data were collected for the number of views and clicks each ad received. Effect of regulatory fit was measured using logistic regression. Findings Logistic regression analyses demonstrated that there was a strong main effect for keyword, such that users were almost six times as likely to click on a promotion advertisement as a prevention advertisement, as well as a main effect for compatibility, such that users were twice as likely to click on an advertisement with content that was consistent with their keyword. Finally, there was a strong interaction of these two variables, such that the effect of consistent advertisements was stronger for promotion searches than for prevention searches. Research limitations/implications The effect of ad compatibility had medium to large effect sizes, suggesting that individuals’ state may have more influence on advertising response than do individuals’ traits (e.g. personality traits). Measurement of regulatory fit was limited by the constraints of Google AdWords. Practical implications The results of this study provide a possible framework for ad creation for Internet advertisers. Originality/value This paper is the first study to demonstrate the utility of regulatory focus theory in online advertising. PMID:26430293

2014-01-01

The Internet presents a widely accessible, 24-h means to promote chronic disease management. The objective of this review is to identify studies that used Internet based interventions to promote lifestyle modification among adults with type 2 diabetes. We searched PubMed using the terms: [internet, computer, phone, smartphone, mhealth, mobile health, web based, telehealth, social media, text messages] combined with [diabetes management and diabetes control] through January 2013. Studies were included if they described an Internet intervention, targeted adults with type 2 diabetes, focused on lifestyle modification, and included an evaluation component with behavioral outcomes. Of the 2803 papers identified, nine met inclusion criteria. Two studies demonstrated improvements in diet and/or physical activity and two studies demonstrated improvements in glycemic control comparing web-based intervention with control. Successful studies were theory-based, included interactive components with tracking and personalized feedback, and provided opportunities for peer support. Website utilization declined over time in all studies that reported on it. Few studies focused on high risk, underserved populations. Web-based strategies provide a viable option for facilitating diabetes self-management. Future research is needed on the use of web-based interventions in underserved communities and studies examining website utilization patterns and engagement over time. © 2014 Elsevier Inc.

2013-01-19

The Medical Home model recommends that Children with Special Health Care Needs (CSHCN) receive a medical care plan, outlining the child's major medical issues and care needs to assist with care coordination. While care plans are a primary component of effective care coordination, the creation and maintenance of care plans is time, labor, and cost intensive, and the desired content of the care plan has not been studied. The purpose of this qualitative study was to understand the usefulness and desired content of comprehensive care plans by exploring the perceptions of parents and health care providers (HCPs) of children with medical complexity (CMC). This qualitative study utilized in-depth semi-structured interviews and focus groups. HCPs (n = 15) and parents (n = 15) of CMC who had all used a comprehensive care plan were recruited from a tertiary pediatric academic health sciences center. Themes were identified through grounded theory analysis of interview and focus group data. A multi-dimensional model of perceived care plan usefulness emerged. The model highlights three integral aspects of the care plan: care plan characteristics, activating factors and perceived outcomes of using a care plan. Care plans were perceived as a useful tool that centralized and focused the care of the child. Care plans were reported to flatten the hierarchical relationship between HCPs and parents, resulting in enhanced reciprocal information exchange and strengthened relationships. Participants expressed that a standardized template that is family-centered and includes content relevant to both the medical and social needs of the child is beneficial when integrated into overall care planning and delivery for CMC. Care plans are perceived to be a useful tool to both health care providers and parents of CMC. These findings inform the utility and development of a comprehensive care plan template as well as a model of how and when to best utilize care plans within family-centered models of care.

Studies have often ignored examining the role of community- and district-level factors in the utilization of maternity healthcare services, particularly in Indian contexts. The Social Determinants of Health framework emphasizes the role of governance and government policies, the measures for which are rarely incorporated in single-level individual analysis. This study examines factors associated with maternal healthcare utilization in nine high focus states in India, which shares more than half of the total maternal deaths in the country; accounting for individual-, household-, community- and district-level characteristics. The required data are extracted from the third round of the nationally representative District Level Household and Facility Survey conducted during 2007-08. Multilevel analyses were applied to three maternity outcomes, namely, four or more antenatal care visits, skilled birth attendance and post-natal care after birth. Results show that along with individual-/household-level factors, community and district-level factors influence the pattern of utilization of maternal healthcare services significantly. At the community level, the odds of maternal healthcare utilization were lower in rural areas and in communities with a high concentration of poor and illiterate women. Moreover, the average population coverage of primary health centres (PHCs), availability of labour room in PHC and percentage of registered pregnancies were significant factors at the district level that influenced the use of maternity care services. The study also found a strong association between the extent of previous use of maternal healthcare and its effect on subsequent usage patterns. This study highlights the role of strengthening public health infrastructure at district level in the study area, and promoting awareness about available healthcare services and subsidized schemes in the community. To reach out to rural and underprivileged communities and to apply a participatory approach from the programme officials are issues to delve into.

Why do multi-attribute utility instruments produce different utilities: the relative importance of the descriptive systems, scale and 'micro-utility' effects.

PubMed

Richardson, Jeff; Iezzi, Angelo; Khan, Munir A

2015-08-01

Health state utilities measured by the major multi-attribute utility instruments differ. Understanding the reasons for this is important for the choice of instrument and for research designed to reconcile these differences. This paper investigates these reasons by explaining pairwise differences between utilities derived from six multi-attribute utility instruments in terms of (1) their implicit measurement scales; (2) the structure of their descriptive systems; and (3) 'micro-utility effects', scale-adjusted differences attributable to their utility formula. The EQ-5D-5L, SF-6D, HUI 3, 15D and AQoL-8D were administered to 8,019 individuals. Utilities and unweighted values were calculated using each instrument. Scale effects were determined by the linear relationship between utilities, the effect of the descriptive system by comparison of scale-adjusted values and 'micro-utility effects' by the unexplained difference between utilities and values. Overall, 66 % of the differences between utilities was attributable to the descriptive systems, 30.3 % to scale effects and 3.7 % to micro-utility effects. Results imply that the revision of utility algorithms will not reconcile differences between instruments. The dominating importance of the descriptive system highlights the need for researchers to select the instrument most capable of describing the health states relevant for a study. Reconciliation of inconsistent utilities produced by different instruments must focus primarily upon the content of the descriptive system. Utility weights primarily determine the measurement scale. Other differences, attributable to utility formula, are comparatively unimportant.

The development of a methodology to assess the potential impacts of distributed photovoltaic (PV) systems on electric utility systems, including subtransmission and distribution networks, and to apply that methodology to several illustrative examples was developed. The investigations focused upon five specific utilities. Impacts upon utility system operations and generation mix were assessed using accepted utility planning methods in combination with models that simulate PV system performance and life cycle economics. Impacts on the utility subtransmission and distribution systems were also investigated. The economic potential of distributed PV systems was investigated for ownership by the utility as well as by the individual utility customer.

City-scale analysis of water-related energy identifies more cost-effective solutions.

PubMed

Lam, Ka Leung; Kenway, Steven J; Lant, Paul A

2017-02-01

Energy and greenhouse gas management in urban water systems typically focus on optimising within the direct system boundary of water utilities that covers the centralised water supply and wastewater treatment systems, despite a greater energy influence by the water end use. This work develops a cost curve of water-related energy management options from a city perspective for a hypothetical Australian city. It is compared with that from the water utility perspective. The curves are based on 18 water-related energy management options that have been implemented or evaluated in Australia. In the studied scenario, the cost-effective energy saving potential from a city perspective (292 GWh/year) is far more significant than that from a utility perspective (65 GWh/year). In some cases, for similar capital cost, if regional water planners invested in end use options instead of utility options, a greater energy saving potential at a greater cost-effectiveness could be achieved in urban water systems. For example, upgrading a wastewater treatment plant for biogas recovery at a capital cost of $27.2 million would save 31 GWh/year with a marginal cost saving of $63/MWh, while solar hot water system rebates at a cost of $28.6 million would save 67 GWh/year with a marginal cost saving of $111/MWh. Options related to hot water use such as water-efficient shower heads, water-efficient clothes washers and solar hot water system rebates are among the most cost-effective city-scale opportunities. This study demonstrates the use of cost curves to compare both utility and end use options in a consistent framework. It also illustrates that focusing solely on managing the energy use within the utility would miss substantial non-utility water-related energy saving opportunities. There is a need to broaden the conventional scope of cost curve analysis to include water-related energy and greenhouse gas at the water end use, and to value their management from a city perspective. This would create opportunities where the same capital investment could achieve far greater energy savings and greenhouse gas emissions abatement. Copyright © 2016 Elsevier Ltd. All rights reserved.

Measuring the equity of inpatient utilization in Chinese rural areas

PubMed Central

2011-01-01

Background As an important outcome of the health system, equity in health service utilization has attracted an increasing amount of attention in the literature on health reform in China in recent years. The poor, who frequently require more services, are often the least able to pay, while the wealthy utilize disproportionately more services although they have less need. Whereas equity in health service utilization between richer and poorer populations has been studied in urban areas, the equity in health service utilization in rural areas has received little attention. With improving levels of economic development, the introduction of health insurance and increasing costs of health services, health service utilization patterns have changed dramatically in rural areas in recent years. However, previous studies have shown neither the extent of utilization inequity, nor which factors are associated with utilization inequity in rural China. Methods This paper uses previously unavailable country-wide data and focuses on income-related inequity of inpatient utilization and its determinants in Chinese rural areas. The data for this study come from the Chinese National Health Services Surveys (NHSS) conducted in 2003 and 2008. To measure the level of inequity in inpatient utilization over time, the concentration index, decomposition of the concentration index, and decomposition of change in the concentration index are employed. Results This study finds that even with the same need for inpatient services, richer individuals utilize more inpatient services than poorer individuals. Income is the principal determinant of this pro-rich inpatient utilization inequity- wealthier individuals are able to pay for more services and therefore use more services regardless of need. However, rising income and increased health insurance coverage have reduced the inequity in inpatient utilization in spite of increasing inpatient prices. Conclusions There remains a strong pro-rich inequity of inpatient utilization in rural China. However, a narrowing income gap between the rich and poor and greater access to health insurance has effectively reduced income inequality, equalizing access to care. This suggests that the most effective way to reduce the inequity is to narrow the gap of income between the rich and poor while adopting social risk protection. PMID:21854641

Biomass resources are attractive carbon sources for bioproduction because of their sustainability. Many studies have been performed using biomass resources to produce sugars as carbon sources for cell factories. Expression of biomass hydrolyzing enzymes in cell factories is an important approach for constructing biomass-utilizing bioprocesses because external addition of these enzymes is expensive. In particular, yeasts have been extensively engineered to be cell factories that directly utilize biomass because of their manageable responses to many genetic engineering tools, such as gene expression, deletion and editing. Biomass utilizing bioprocesses have also been developed using these genetic engineering tools to construct metabolic pathways. However, sugar input and product output from these cells are critical factors for improving bioproduction along with biomass utilization and metabolic pathways. Transporters are key components for efficient input and output activities. In this review, we focus on transporter engineering in yeast to enhance bioproduction from biomass resources. © FEMS 2017.

Eye diseases causing visual impairment increase with age. Thus, seeking eye care has a higher probability in older people. In this study, the rate of utilization of outpatient eye care services in Germany was analyzed. The analyses focused on older persons and persons in need of either home-based or facility-based long-term care. A descriptive secondary data analysis of health insurance data of the AOK Baden-Württemberg from 2016 was conducted. The study population comprised all insured persons on 1 January 2016. The cohort of older persons (60 years+) was further stratified by the type of care (home-based/facility-based) and the level of care (0-3). The utilization of outpatient eye care services was defined by the reimbursement for an ophthalmologist's provision of service. While 39.3% of the study population 60+ years old sought eye care, the utilization rate was lower among people in need of home-based (33.0%) and facility-based care (19.3%). The utilization rates showed comparable age-dependent patterns, except for persons in need of facility-based care where rates were similar for all age groups. Utilization rates were negatively associated with increasing care levels. Only people with care level 0 showed lower utilization rates than people with care level 1. Utilization rates of eye healthcare services among older persons are considerably influenced by the need of long-term care, by the form of care as well as by the level of care.

Rural, low-income pregnant women and their children are at high risk for poor oral health and have low utilization rates of dental care. The Baby Smiles study was designed to increase low-income pregnant women's utilization of dental care, increase young children's dental care utilization, and improve home oral health care practices. Baby Smiles was a five-year, four-site randomized intervention trial with a 2 × 2 factorial design. Four hundred participants were randomly assigned to one of four treatment arms in which they received either brief Motivational Interviewing (MI) or health education (HE) delivered during pregnancy and after the baby was born. In the prenatal study phase, the interventions were designed to encourage dental utilization during pregnancy. After childbirth, the focus was to utilize dental care for the infant by age one. The two primary outcome measures were dental utilization during pregnancy or up to two months postpartum for the mother, and preventive dental utilization by 18 months of age for the child. Medicaid claims data will be used to assess the primary outcomes. Questionnaires were administered at enrollment and 3, 9 and 18 months postpartum (study end) to assess mediating and moderating factors. This trial can help define the most effective way to provide one-on-one counseling to pregnant women and new mothers regarding visits to the dentist during pregnancy and after the child is born. It supports previous work demonstrating the potential of reducing mother-to-child transmission of Streptococcus mutans and the initiation of dental caries prevention in early childhood.

O'Dea, Bridianne; Campbell, Andrew

2011-01-01

The impact of Internet communication on adolescent social development is of considerable importance to health professionals, parents and teachers. Online social networking and instant messaging programs are popular utilities amongst a generation of techno-savvy youth. Although these utilities provide varied methods of communication, their social benefits are still in question. This study examined the relationship between online social interaction, perceived social support, self-esteem and psychological distress amongst teens. A total of 400 participants (M(age) = 14.31 years) completed an online survey consisting of parametric and non-parametric measures. No significant relationship was found between online interaction and social support. Time spent interacting online was negatively correlated with self-esteem and psychological distress. While previous research has focused on young adults, this study examines the impact of online social networking on emerging teens. It highlights the need for continued caution in the acceptance of these utilities.

Managing for resilience: an information theory-based ...

EPA Pesticide Factsheets

Ecosystems are complex and multivariate; hence, methods to assess the dynamics of ecosystems should have the capacity to evaluate multiple indicators simultaneously. Most research on identifying leading indicators of regime shifts has focused on univariate methods and simple models which have limited utility when evaluating real ecosystems, particularly because drivers are often unknown. We discuss some common univariate and multivariate approaches for detecting critical transitions in ecosystems and demonstrate their capabilities via case studies. Synthesis and applications. We illustrate the utility of an information theory-based index for assessing ecosystem dynamics. Trends in this index also provide a sentinel of both abrupt and gradual transitions in ecosystems. In response to the need to identify leading indicators of regime shifts in ecosystems, our research compares traditional indicators and Fisher information, an information theory based method, by examining four case study systems. Results demonstrate the utility of methods and offers great promise for quantifying and managing for resilience.

Health needs and health care utilization among rural, low-income women.

Simmons, Leigh Ann; Anderson, Elaine A; Braun, Bonnie

2008-01-01

This study examined the correlates of health service utilization in a sample of low-income, rural women. Self-reported data were from Rural Families Speak (N = 275), a multi-state study of low-income, rural families in the U.S. collected in 2002. Findings indicated that women with health insurance, a regular doctor, and poorer overall physical health had higher incident rates of physician visits. Women who were divorced, separated or widowed and had more chronic health problems had higher incidence rates of emergency department (ED) use, while women living in counties with higher primary care physician rates had lower incidence rates of ED use. Future research and policies should focus on improved access to health insurance, increasing physician availability in rural areas, and providing rural women with a usual source of care, so as to reduce emergency services utilization for non-emergent needs and improve health status for this population.

Circulating tumor cells (CTCs) are rare tumor cells and have been investigated as diagnostic, prognostic and predictive biomarkers in many types of cancer. Although CTCs are not currently used in clinical practice, CTC studies have accumulated a high level of clinical validity, especially in breast, lung, prostate and colorectal cancers. In this review, we present an overview of the current clinical validity of CTCs in metastatic and non-metastatic disease, and the main concepts and studies investigating the clinical utility of CTCs. In particular, this review will focus on breast, lung, colorectal and prostate cancer. Three major topics concerning the clinical utility of CTC are discussed-(1) treatment based on CTCs used as liquid biopsy, (2) treatment based on CTC count or CTC variations, and (3) treatment based on CTC biomarker expression. A summary of published or ongoing phase II and III trials is also presented.

Objective To describe mental health services utilization for adolescents after attempted suicide, explore factors related to treatment compliance, and determine the relationship between compliance and suicidality. Method Eighty-five adolescents (ages 13–18) who had attempted suicide and their families were recruited from four psychiatric hospitals and were evaluated for symptoms of psychopathology. Subsequent assessments were conducted every six months for two years to determine treatment utilization, treatment compliance (non-adherence to medication regimes or non-attendance of psychosocial treatments against provider advice), attitudes towards treatments utilized, and further suicide attempts and ideation. Results Adolescents with a disruptive behavior disorder diagnosis were less compliant with individual psychotherapy, as were those with a substance dependence other than alcohol or marijuana. Those with an affective/anxiety disorder diagnosis were less compliant with psychopharmacological interventions (6 months post attempt). Parental perception of treatment as helpful was predictive of greater compliance, while adolescents' attitudes towards treatment were not predictive of compliance. Finally, compliance with treatment was not generally predictive of future suicidality. Conclusion Interventions focused on increasing compliance with mental health treatment for adolescent suicide attempters should focus on specific child psychopathology, as well as parental attitudes towards treatment.

New discoveries in basic science are creating extraordinary opportunities to design novel biomedical preventions and therapeutics for human disease. But the clinical evaluation of these new interventions is, in many instances, being hindered by a variety of legal, regulatory, policy and operational factors, few of which enhance research quality, the safety of study participants or research ethics. With the goal of helping increase the efficiency and effectiveness of clinical research, we have examined how the integration of utilization-focused evaluation with elements of business process modeling can reveal opportunities for systematic improvements in clinical research. Using data from the NIH global HIV/AIDS clinical trials networks, we analyzed the absolute and relative times required to traverse defined phases associated with specific activities within the clinical protocol lifecycle. Using simple median duration and Kaplan-Meyer survival analysis, we show how such time-based analyses can provide a rationale for the prioritization of research process analysis and re-engineering, as well as a means for statistically assessing the impact of policy modifications, resource utilization, re-engineered processes and best practices. Successfully applied, this approach can help researchers be more efficient in capitalizing on new science to speed the development of improved interventions for human disease.

Although previous research has examined barriers and facilitators of HIV testing among men who have sex with men (MSM) in China, few studies have focused on social factors, including homophobia and internalized homophobia. This study utilized data from a global online survey to determine correlates of HIV testing as part of a subanalysis focused on Chinese MSM. Controlling for age, HIV knowledge, number of sexual partners, and other covariates, ever having tested for HIV was significantly correlated with lower internalized homophobia. This study suggests that stigma associated with sexual orientation may serve as a barrier to participation in HIV testing and other health-promoting behaviors.

Ketchen Lipson, Sarah; Gaddis, S Michael; Heinze, Justin; Beck, Kathryn; Eisenberg, Daniel

2015-01-01

On US college campuses, mental health problems are highly prevalent, appear to be increasing, and are often untreated. Concerns about student mental health are well documented, but little is known about potential variations across the diversity of institutions of higher education. Participants were 43,210 undergraduates at 72 campuses that participated in the Healthy Minds Study from 2007 to 2013. Multivariable logistic regressions focus on associations between institutional characteristics and student mental health and treatment utilization. The following institutional characteristics are associated with worse mental health: doctoral-granting, public, large enrollment, nonresidential, less competitive, and lower graduation rates. Among students with apparent mental health problems, treatment utilization is higher at doctorate-granting institutions, baccalaureate colleges, institutions with small enrollments, and schools with strong residential systems. Although high rates of mental health problems and low treatment utilization are major concerns at all types of institutions of higher education, substantial variation occurs across campuses.

Comparison between the Health Belief Model and Subjective Expected Utility Theory: predicting incontinence prevention behaviour in post-partum women.

PubMed

Dolman, M; Chase, J

1996-08-01

A small-scale study was undertaken to test the relative predictive power of the Health Belief Model and Subjective Expected Utility Theory for the uptake of a behaviour (pelvic floor exercises) to reduce post-partum urinary incontinence in primigravida females. A structured questionnaire was used to gather data relevant to both models from a sample antenatal and postnatal primigravida women. Questions examined the perceived probability of becoming incontinent, the perceived (dis)utility of incontinence, the perceived probability of pelvic floor exercises preventing future urinary incontinence, the costs and benefits of performing pelvic floor exercises and sources of information and knowledge about incontinence. Multiple regression analysis focused on whether or not respondents intended to perform pelvic floor exercises and the factors influencing their decisions. Aggregated data were analysed to compare the Health Belief Model and Subjective Expected Utility Theory directly.

2017-04-01

Health care organizations are under increasing pressure to deliver value by improving test utilization management. Many factors, including organizational factors, could affect utilization performance. Past research has focused on the impact of specific interventions in single organizations. The impact of organizational factors is unknown. The objective of this study is to determine whether testing patterns are subject to organizational effects, ie, are utilization patterns for individual tests correlated within organizations. Comparative analysis of ordering patterns (positivity rates for three genetic tests) across 659 organizations. Hierarchical regression was used to assess the impact of organizational factors after controlling for test-level factors (mutation prevalence) and hospital bed size. Test positivity rates were correlated within organizations. Organizations have a statistically significant impact on the positivity rate of three genetic tests. © American Society for Clinical Pathology, 2017. All rights reserved.

Assimilation and health service utilization of Korean immigrant women.

PubMed

Son, Juyeon

2013-11-01

In this case study, I present descriptive findings with regard to immigrant incorporation and health service utilization. Using focus groups and survey of Korean immigrant women in Wisconsin, I examine whether the ways in which they adapt to the U.S. society is relevant to their health services utilization and the alternatives they seek when available health services are less than satisfactory. The findings suggest that adherence to Korean identity appears to be associated with health service utilization. This is evident in the immigrants' evaluation of the U.S. health services as compared to those of Korea, and the consideration given by these immigrants to seeking health services in Korea instead of the United States. Such concerns on the part of these immigrants have important implications for health researchers, as they highlight the significance of immigrants' transnational experiences and their sense of personal agency in the use of health care.

Life-cycle energy production and emissions mitigation by comprehensive biogas-digestate utilization.

PubMed

Chen, Shaoqing; Chen, Bin; Song, Dan

2012-06-01

In the context of global energy shortages and climate change, developing biogas plants with links to agricultural system has become an important strategy for cleaner rural energy and renewable agriculture. In this study, a life-cycle energy and environmental assessment was performed for a biogas-digestate utilization system in China. The results suggest that biogas utilization (heating, illumination, and fuel) and comprehensive digestate reuse are of equal importance in the total energy production of the system, and they also play an important role in systemic greenhouse gas mitigation. Improvement can be achieved in both energy production and emissions mitigation when the ratio of the current three biogas utilization pathways is adjusted. Regarding digestate reuse, a tradeoff between energy and environmental performance can be obtained by focusing on the substitution for top-dressing, base fertilizers, and the application to seed soaking.

2004-01-01

To identify the extent to which rural nurses utilize evidence-based practice guidelines from scientific research in their practice; to describe both previous and current research utilization activities in which they have participated, and to identify the specific barriers they face in their practice settings. Data for this descriptive study were collected through questionnaires with open-ended questions focused on (a) current utilization of nursing research findings, (b) previous involvement in nursing research activities, and (c) participation in medical research activities. The participants were 106 nurses from various practice areas in six rural counties of a southwestern state in the United States. Results revealed that only 20.8% of the participants stated they were currently involved in research utilization, and they were mostly nurses with bachelor's degrees. The two most common areas of current research utilization were pain management and pressure ulcer prevention and management. Barriers to research utilization, such as rural isolation and lack of nursing research consultants, were identified. The types of research utilization activities identified by these nurses indicate how much the facilities in which these nurses work in the rural areas are striving with the utilization of available scientific evidence. Rural nurses face unique barriers related to situational and geographic factors, with implications for nursing administrators, researchers, and educators.

Objective The purpose of this article is to examine the relationship of wealth and income and the relative impact of each on dental utilization in a population of older Americans, using data from the Health and Retirement Study (HRS). Methods Data from the Health and Retirement Study (HRS) were analyzed for U.S. individuals aged 51 years and older during the 2008 wave of the HRS. The primary focus of the analysis is the relationship between wealth, income and dental utilization. We estimate a multivariable model of dental use controlling for wealth, income and other potentially confounding covariates. Results We find that both wealth and income each have a strong and independent positive effect on dental care use of older Americans [p<.05]. A test of the interaction between income and wealth in our model failed to show that the impact on dental care utilization as wealth increases depends on a person's income level, or, alternatively, that the impact on dental use as income increases depends on a person's household wealth status [p>.05]. Conclusions Relative to those living in the wealthiest U.S. households, the likelihood of utilizing dental care appears to decrease with a decline in wealth. The likelihood of utilizing dental care also appears to decrease with a decline in income as well. PMID:22515635

To better understand Australia-dwelling Middle Eastern women's lack of service utilization in cardiovascular health, we undertook a study to investigate their understandings and meanings of cardiovascular disease (CVD) and its risk factors. Eight focus groups were conducted in community settings with Turkish, Persian, and Arab women. We found that the women understated their risk of CVD, faced many barriers in reducing their risks, and perceived stress as the most significant contributor to CVD. Women described their stress as primarily emanating from issues surrounding migration and acculturation. Implications for development and delivery of tailored health interventions for Middle Eastern women are discussed.

Chen, Xiao; Liao, JianQiao; Wu, Weijiong; Zhang, Wei

2017-01-01

Many studies have evaluated how the characteristics of feedback receiver, feedback deliverer and feedback information influence psychological feedback reactions of the feedback receiver while largely neglecting that feedback intervention is a kind of social interaction process. To address this issue, this study proposes that employees' perceived insider status (PIS), as a kind of employee-organization relationship, could also influence employees' reactions to supervisory feedback. In particular, this study investigates the influence of PIS focusing on affective and cognitive feedback reactions, namely feedback satisfaction and feedback utility. Surveys were conducted in a machinery manufacturing company in the Guangdong province of China. Samples were collected from 192 employees. Data analysis demonstrated that PIS and feedback utility possessed a U-shaped relationship, whereas PIS and feedback satisfaction exhibited positively linear relationships. The analysis identified two kinds of mediating mechanisms related to feedback satisfaction and feedback utility. Internal feedback motivation attribution partially mediated the relationship between PIS and feedback satisfaction but failed to do the same with respect to the relationship between PIS and feedback utility. In contrast, external feedback motivation attribution partially mediated the relationship between PIS and feedback utility while failing to mediate the relationship between PIS and feedback satisfaction. Theoretical contributions and practical implications of the findings are discussed at the end of the paper.

Background Health care portals have the potential to provide consumers with timely, transparent access to health care information and engage them in the care process. Objective The objective was to examine the use, utility, and impact on engagement in care and caregiver-provider communication of a client/family portal providing access to electronic health records (EHRs) and secure, 2-way e-messaging with care providers. Methods We conducted a prospective, mixed-methods study involving collection of caregivers’ portal usage information over a 14-month period (from portal introduction in January 2015 to the end of the study period in March 2016), a Web-based survey for caregivers administered after a minimum of 2 months’ exposure to the portal and repeated 2 months later, and focus groups or individual interviews held with caregivers and service providers at the same points in time. The survey assessed caregivers’ perceptions of the utility of and satisfaction with the EHR and e-messaging, and the portal’s impact on client engagement and perceptions of caregiver-provider communication. A total of 18 caregivers (parents) completed surveys and 6 also took part in focus groups or interviews. In addition, 5 service providers from different disciplines took part in focus groups or interviews. Results Although usage patterns varied, the typical pattern was a steady level of use (2.5 times a month over an average of 9 months), which is higher than typically reported use. The portal pages most frequently accessed were the home page, health record main page, appointment main page, and reports main page. The Web-based survey captured caregivers’ perceptions of usefulness of and satisfaction with the EHR and portal messaging, as well as the portal’s impact on their engagement in care and perceptions of caregiver-provider communication. The surveys indicated a moderate degree of utility of and satisfaction with the portal features, and a low but emerging impact on engagement in care and caregiver-provider communication (survey scales measuring these outcomes displayed excellent internal consistency, with Cronbach alpha ranging from .89 to .95). Qualitative themes from focus groups and interviews supported and extended the survey findings. Caregivers and service providers saw appreciable information benefits and provided recommendations to increase portal use and utility. Caregivers focused on the scope of organizational adoption of the portal system and indicated their hopes for the future of the portal, whereas service providers were concerned about how to best manage their investment of time and effort in preparing client-friendly reports and messaging clients via the portal. Conclusions Overall, the findings show the promise of the portal and the need for ongoing evaluation to show the portal’s ultimate potential in enhancing engagement in care and communication with care providers.

Scientific knowledge can help develop interventions that improve public health. The objectives of this review are (1) to describe the status of research on knowledge transfer strategies in the field of complex social interventions in public health and (2) to identify priorities for future research in this field. A scoping study is an exploratory study. After searching databases of bibliographic references and specialized periodicals, we summarized the relevant studies using a predetermined assessment framework. In-depth analysis focused on the following items: types of knowledge transfer strategies, fields of public health, types of publics, types of utilization, and types of research specifications. From the 1,374 references identified, we selected 26 studies. The strategies targeted mostly administrators of organizations and practitioners. The articles generally dealt with instrumental utilization and most often used qualitative methods. In general, the bias risk for the studies is high. Researchers need to consider the methodological challenges in this field of research in order to improve assessment of more complex knowledge transfer strategies (when they exist), not just diffusion/dissemination strategies and conceptual and persuasive utilization.

Personal and general belief in a just world as judgement norms.

PubMed

Alves, Hélder; Correia, Isabel

2010-06-01

Research on the belief in a just world (BJW) has focused on its intra-individual functions (e.g., psychological well-being) and its inter-individual consequences (e.g., derogation of victims). Recent theorizing, however, has indicated that the BJW may also have more societal functions and consequences, serving as a legitimizing device of the status quo. The studies in the current paper focus on this latter view and are based on Alves and Correia's ( 2008 ) research which found that the expression of high personal and general belief in a just world is injunctively normative. Two experimental studies aimed at ascertaining three issues: (1) the dimension(s) of social value (social utility and/or social desirability) on which the BJW normativity anchors; (2) whether the expression of moderate BJW is also injunctively normative; and (3) whether the injunctive normativity of the BJW is related to perceptions of truth. Results indicate that moderate and high personal and general BJW are normative. Yet, whereas the normativity of personal BJW anchors both on social utility and social desirability, that of general BJW anchors only on social utility. We discuss personal and general BJW as judgement norms, whose normativity may not be personally acknowledged (in the case of general BJW) and does not necessarily derive from being perceived as true, but from the fact that such norms carry social value at least in individualistic societies.

Observations of Near-Surface Relative Humidity in a Wind Turbine Array Boundary Layer Using an Instrumented Unmanned Aerial System

NASA Astrophysics Data System (ADS)

Adkins, K. A.; Sescu, A.

2016-12-01

Simulation and modeling have shown that wind farms have an impact on the near-surface atmospheric boundary layer (ABL) as turbulent wakes generated by the turbines enhance vertical mixing. These changes alter downstream atmospheric properties. With a large portion of wind farms hosted within an agricultural context, changes to the environment can potentially have secondary impacts such as to the productivity of crops. With the exception of a few observational data sets that focus on the impact to near-surface temperature, little to no observational evidence exists. These few studies also lack high spatial resolution due to their use of a limited number of meteorological towers or remote sensing techniques. This study utilizes an instrumented small unmanned aerial system (sUAS) to gather in-situ field measurements from two Midwest wind farms, focusing on the impact that large utility-scale wind turbines have on relative humidity. Wind turbines are found to differentially alter the relative humidity in the downstream, spanwise and vertical directions under a variety of atmospheric stability conditions.

In Germany, utilization of ambulatory health care is high compared to other countries. Classical models of health care utilization cannot sufficiently explain these differences. The aim of this study was to explore relevant factors which can explain the higher health care utilization in Germany. In this article, we focus on regulations regarding sickness certification as a potential factor. An explorative qualitative study design. We conducted episodic interviews with 20 patients in Germany and 20 patients in Norway and participant observation in four primary care practices each. Additionally, we conducted a context analysis of relevant health care system related factors which emerged during the study. Qualitative data analysis was done by thematic coding in the framework of grounded theory. The need for a sickness certificate was an important reason for encounter in Germany, especially regarding minor illnesses. Sickness certification is a societal topic. GPs play a double role regarding sickness certification, both as the patients' advocate and as an expert witness for social security services. In Norway, longer periods of self-administered sickness certification and more differentiated possibilities of sickness certification have been introduced successfully. Our results point to regulations regarding sickness certification as a relevant factor for higher health care utilization in Germany. In pilot studies, the effect of extended self-certification of sickness and part-time sickness certification should be further assessed. Copyright © 2015. Published by Elsevier GmbH.

The study was done to describe the dental caries experience and dental care utilization among Tibetan refugee-background children in Paonta Sahib, India. The study was conducted on 254 school children in a Tibetan settlement in Paonta Sahib. Examination was done as per World Health Organization Oral Health Assessment criteria (2013). Data on dental services utilization was obtained from the parents of children using a structured questionnaire. Oral examination of 254 school children aged 6-18 years revealed an overall dental caries prevalence of 79.5%. The dental caries experience was greater in the mixed dentition (84%) than secondary dentition (77.3%). The mean DMFT was associated with sex and dental visiting patterns. About 60% children had never visited a dentist before. The main reason for dental visit was tooth removal (43%). The prevalence of dental caries among Tibetan refugee-background school children was high and utilization of dental care was low. A comprehensive oral health program focusing on preventive care and oral health education is recommended.

To identify, and compare relative importance of, factors associated with antenatal care (ANC) utilization in rural Balochistan, toward framing a policy to increase such utilization. This cross sectional study was conducted among 513 pregnant women in Jhal Magsi District, Balochistan, in 2011. A standardized interviewer-administered questionnaire was used. Predisposing, enabling, and reinforcing factors were evaluated with generalized linear models (Poisson distribution and log link). Prevalence of any ANC was only 14.4%. Predisposing, enabling, and reinforcing factors were all important determinants of ANC utilization. Reinforcing factors were clearly most important, husband's support for ANC was more important than support from other community members. Among predisposing factors, higher income, education, occupation, and better knowledge regarding benefits of ANC were positively and statistically significantly associated with ANC However increased number of children showed negative association. Complications free pregnancy showed positive significant association with ANC at public health facility among enabling factors. It is very important to increase antenatal care utilization in the study area and similar areas. Policy to achieve this should focus on enhancing support from the husband.

Utility functions predict variance and skewness risk preferences in monkeys

PubMed Central

Genest, Wilfried; Stauffer, William R.; Schultz, Wolfram

2016-01-01

Utility is the fundamental variable thought to underlie economic choices. In particular, utility functions are believed to reflect preferences toward risk, a key decision variable in many real-life situations. To assess the validity of utility representations, it is therefore important to examine risk preferences. In turn, this approach requires formal definitions of risk. A standard approach is to focus on the variance of reward distributions (variance-risk). In this study, we also examined a form of risk related to the skewness of reward distributions (skewness-risk). Thus, we tested the extent to which empirically derived utility functions predicted preferences for variance-risk and skewness-risk in macaques. The expected utilities calculated for various symmetrical and skewed gambles served to define formally the direction of stochastic dominance between gambles. In direct choices, the animals’ preferences followed both second-order (variance) and third-order (skewness) stochastic dominance. Specifically, for gambles with different variance but identical expected values (EVs), the monkeys preferred high-variance gambles at low EVs and low-variance gambles at high EVs; in gambles with different skewness but identical EVs and variances, the animals preferred positively over symmetrical and negatively skewed gambles in a strongly transitive fashion. Thus, the utility functions predicted the animals’ preferences for variance-risk and skewness-risk. Using these well-defined forms of risk, this study shows that monkeys’ choices conform to the internal reward valuations suggested by their utility functions. This result implies a representation of utility in monkeys that accounts for both variance-risk and skewness-risk preferences. PMID:27402743

Mars 2020 Model Based Systems Engineering Pilot

NASA Technical Reports Server (NTRS)

Dukes, Alexandra Marie

2017-01-01

The pilot study is led by the Integration Engineering group in NASA's Launch Services Program (LSP). The Integration Engineering (IE) group is responsible for managing the interfaces between the spacecraft and launch vehicle. This pilot investigates the utility of Model-Based Systems Engineering (MBSE) with respect to managing and verifying interface requirements. The main objectives of the pilot are to model several key aspects of the Mars 2020 integrated operations and interface requirements based on the design and verification artifacts from Mars Science Laboratory (MSL) and to demonstrate how MBSE could be used by LSP to gain further insight on the interface between the spacecraft and launch vehicle as well as to enhance how LSP manages the launch service. The method used to accomplish this pilot started through familiarization of SysML, MagicDraw, and the Mars 2020 and MSL systems through books, tutorials, and NASA documentation. MSL was chosen as the focus of the model since its processes and verifications translate easily to the Mars 2020 mission. The study was further focused by modeling specialized systems and processes within MSL in order to demonstrate the utility of MBSE for the rest of the mission. The systems chosen were the In-Flight Disconnect (IFD) system and the Mass Properties process. The IFD was chosen as a system of focus since it is an interface between the spacecraft and launch vehicle which can demonstrate the usefulness of MBSE from a system perspective. The Mass Properties process was chosen as a process of focus since the verifications for mass properties occur throughout the lifecycle and can demonstrate the usefulness of MBSE from a multi-discipline perspective. Several iterations of both perspectives have been modeled and evaluated. While the pilot study will continue for another 2 weeks, pros and cons of using MBSE for LSP IE have been identified. A pro of using MBSE includes an integrated view of the disciplines, requirements, and verifications leading up to launch. The model allows IE to understand the relationships between disciplines throughout test activities and verifications. Additionally, the relationships between disciplines and integration tasks are generally consistent. The model allows for the generic relationships and tasks to be captured and used throughout multiple mission models should LSP further pursue MBSE. A con of MBSE is the amount of time it takes upfront to understand MBSE and create a useful model. The upfront time it takes to create a useful model is heavily discussed in MBSE literature and is a consistent con throughout the known applications of MBSE. The need to understand SysML and the software chosen also poses the possibility of a "bottleneck" or one person being the sole MBSE user for the working group. The utility of MBSE will continue to be evaluated through the remainder of the study. In conclusion, the original objectives of the pilot study were to use artifacts from MSL to model key aspects of Mars 2020 and demonstrate how MBSE could be used by LSP to gain insight into the spacecraft and launch vehicle interfaces. Progress has been made in modeling and identifying the utility of MBSE to LSP IE and will continue to be made until the pilot study's conclusion in mid-August. The results of this study will produce initial models, modeling instructions and examples, and a summary of MBSE's utility for future use by LSP.

Simwita, Yusta W; Helgheim, Berit I

2016-01-01

Purpose Worldwide more than two billion people lack appropriate access to surgical services due to mismatch between existing human resource and patient demands. Improving utilization of existing workforce capacity can reduce the existing gap between surgical demand and available workforce capacity. In this paper, the authors use discrete event simulation to explore the care process at an orthopedic department. Our main focus is improving utilization of surgeons while minimizing patient wait time. Methods The authors collaborated with orthopedic department personnel to map the current operations of orthopedic care process in order to identify factors that influence poor surgeons utilization and high patient waiting time. The authors used an observational approach to collect data. The developed model was validated by comparing the simulation output with the actual patient data that were collected from the studied orthopedic care process. The authors developed a proposal scenario to show how to improve surgeon utilization. Results The simulation results showed that if ancillary services could be performed before the start of clinic examination services, the orthopedic care process could be highly improved. That is, improved surgeon utilization and reduced patient waiting time. Simulation results demonstrate that with improved surgeon utilizations, up to 55% increase of future demand can be accommodated without patients reaching current waiting time at this clinic, thus, improving patient access to health care services. Conclusion This study shows how simulation modeling can be used to improve health care processes. This study was limited to a single care process; however the findings can be applied to improve other orthopedic care process with similar operational characteristics. PMID:29355193

Clinical utility of BOLD fMRI in preoperative work-up of epilepsy

PubMed Central

Ganesan, Karthik; Ursekar, Meher

2014-01-01

Surgical techniques have emerged as a viable therapeutic option in patients with drug refractory epilepsy. Pre-surgical evaluation of epilepsy requires a comprehensive, multiparametric, and multimodal approach for precise localization of the epileptogenic focus. Various non-invasive techniques are available at the disposal of the treating physician to detect the epileptogenic focus, which include electroencephalography (EEG), video-EEG, magnetic resonance imaging (MRI), functional MRI including blood oxygen level dependent (BOLD) techniques, single photon emission tomography (SPECT), and 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET). Currently, non-invasive high-resolution MR imaging techniques play pivotal roles in the preoperative detection of the seizure focus, and represent the foundation for successful epilepsy surgery. BOLD functional magnetic resonance imaging (fMRI) maps allow for precise localization of the eloquent cortex in relation to the seizure focus. This review article focuses on the clinical utility of BOLD (fMRI) in the pre-surgical work-up of epilepsy patients. PMID:24851002

After a troubled period, however, many utilities have completed major construction programs and face fewer financial constraints in the near term, while other utilities hope to achieve this status shortly. At the same time, many utilities and regulatory commissions are reluctant to begin construction of large new plants, both because of current high reserve margins and because of past unhappy outcomes for ratepayers and investors when load growth proved lower than expected. This study examines the potential long-run financial constraints and risksmore » the electric utility industry faces as a result of the current incentives to delay the start of major new projects as long as possible. The study analyzes industry-wide financial and operating data from 1985 to 2005 under several scenarios. The findings suggest that if the future is no worse than postulated in our scenarios, total construction expenditures and external funding requirements should be manageable at the national level. Also, the study finds that the cost of delaying new construction /en dash/ although possibly significant /en dash/ will depend critically on the relative prices of coal and natural gas which actually occur. Thus this report concludes that the possibility of significant future financial constraints does not appear to be a problem at the national level. There is good reason to believe, however, that there could be a problem under certain adverse conditions for specific regions and for individual utilities. Given the relatively large amount of external funds likely to be needed by some utilities in those situations and the risks investors may perceive in supplying these funds, financial constraints may cause some construction delays. 23 refs., 21 figs., 6 tabs.« less

The impact of health insurance on maternal health care utilization: evidence from Ghana, Indonesia and Rwanda

PubMed Central

Temsah, Gheda; Mallick, Lindsay

2017-01-01

Abstract While research has assessed the impact of health insurance on health care utilization, few studies have focused on the effects of health insurance on use of maternal health care. Analyzing nationally representative data from the Demographic and Health Surveys (DHS), this study estimates the impact of health insurance status on the use of maternal health services in three countries with relatively high levels of health insurance coverage—Ghana, Indonesia and Rwanda. The analysis uses propensity score matching to adjust for selection bias in health insurance uptake and to assess the effect of health insurance on four measurements of maternal health care utilization: making at least one antenatal care visit; making four or more antenatal care visits; initiating antenatal care within the first trimester and giving birth in a health facility. Although health insurance schemes in these three countries are mostly designed to focus on the poor, coverage has been highly skewed toward the rich, especially in Ghana and Rwanda. Indonesia shows less variation in coverage by wealth status. The analysis found significant positive effects of health insurance coverage on at least two of the four measures of maternal health care utilization in each of the three countries. Indonesia stands out for the most systematic effect of health insurance across all four measures. The positive impact of health insurance appears more consistent on use of facility-based delivery than use of antenatal care. The analysis suggests that broadening health insurance to include income-sensitive premiums or exemptions for the poor and low or no copayments can increase use of maternal health care.

Focus group interview: an underutilized research technique for improving theory and practice in health education.

PubMed

Basch, C E

1987-01-01

The purpose of this article is to increase awareness about and stimulate interest in using focus group interviews, a qualitative research technique, to advance the state-of-the-art of education and learning about health. After a brief discussion of small group process in health education, features of focus group interviews are presented, and a theoretical framework for planning a focus group study is summarized. Then, literature describing traditional and health-related applications of focus group interviews is reviewed and a synthesis of methodological limitations and advantages of this technique is presented. Implications are discussed regarding: need for more inductive qualitative research in health education; utility of focus group interviews for research and for formative and summative evaluation of health education programs; applicability of marketing research to understanding and influencing consumer behavior, despite notable distinctions between educational initiatives and marketing; and need for professional preparation faculty to consider increasing emphasis on qualitative research methods.

Economic Evaluations of Pathology Tests, 2010-2015: A Scoping Review.

PubMed

Watts, Rory D; Li, Ian W; Geelhoed, Elizabeth A; Sanfilippo, Frank M; St John, Andrew

2017-09-01

Concerns about pathology testing such as the value provided by new tests and the potential for inappropriate utilization have led to a greater need to assess costs and benefits. Economic evaluations are a formal method of analyzing costs and benefits, yet for pathology tests, questions remain about the scope and quality of the economic evidence. To describe the extent and quality of published evidence provided by economic evaluations of pathology tests from 2010 to 2015. Economic evaluations relating to pathology tests from 2010 to 2015 were reviewed. Eight databases were searched for published studies, and details recorded for the country, clinical focus, type of testing, and consideration of sensitivity, specificity, and false test results. The reporting quality of studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist and cost-effectiveness ratios were analyzed for publication bias. We found 356 economic evaluations of pathology tests, most of which regarded developed countries. The most common economic evaluations were cost-utility analyses and the most common clinical focus was infectious diseases. More than half of the studies considered sensitivity and specificity, but few studies considered the impact of false test results. The average Consolidated Health Economic Evaluation Reporting Standards checklist score was 17 out of 24. Cost-utility ratios were commonly less than $10,000/quality-adjusted life-year or more than $200,000/quality-adjusted life-year. The number of economic evaluations of pathology tests has increased in recent years, but the rate of increase has plateaued. Furthermore, the quality of studies in the past 5 years was highly variable, and there is some question of publication bias in reporting cost-effectiveness ratios.

Amendola, Mary Grace; Nazario, Noelia; Sanchez, Veronica

2016-01-01

Community-based participatory research (CBPR) has become an important research approach for universities to partner with social service agencies by uniting them in project design, planning, implementation, and evaluation. This study involved FOCUS, an urban social service agency, and Rutgers College of Nursing (RUCON) collaboratively conducting a needs assessment to compare the health needs of its clients and their employees' perception of their clients health needs, utilizing CBPR. Qualitative data was collected using the focus group method, field notes, photographs, and observation. The employees of FOCUS facilitated focus groups, participant recruitment, and transcribed and translated data. Three themes emerged: Health Education, Cost of Health Care, and Barriers to Health Care. This study contributes to the growing body of knowledge of integrating the CBPR approach when conducting a community needs assessment with a social service agency. The CBPR approach closely reflects the identified health needs of its clients resulting in interventions that will meet their specific health needs. © 2015 Wiley Periodicals, Inc.

The formation of stable pH gradients with weak monovalent buffers for isoelectric focusing in free solution

Mosher, Richard A.; Thormann, Wolfgang; Graham, Aly; Bier, Milan

1985-01-01

Two methods which utilize simple buffers for the generation of stable pH gradients (useful for preparative isoelectric focusing) are compared and contrasted. The first employs preformed gradients comprised of two simple buffers in density-stabilized free solution. The second method utilizes neutral membranes to isolate electrolyte reservoirs of constant composition from the separation column. It is shown by computer simulation that steady-state gradients can be formed at any pH range with any number of components in such a system.

Can pharmacogenetics explain efficacy and safety of cisplatin pharmacotherapy?

Roco, Ángela; Cayún, Juan; Contreras, Stephania; Stojanova, Jana; Quiñones, Luis

2014-01-01

Several recent pharmacogenetic studies have investigated the variability in both outcome and toxicity in cisplatin-based therapies. These studies have focused on the genetic variability of therapeutic targets that could affect cisplatin response and toxicity in diverse type of cancer including lung, gastric, ovarian, testicular, and esophageal cancer. In this review, we seek to update the reader in this area of investigation, focusing primarily on DNA reparation enzymes and cisplatin metabolism through Glutathione S-Transferases (GSTs). Current evidence indicates a potential application of pharmacogenetics in therapeutic schemes in which cisplatin is the cornerstone of these treatments. Therefore, a collaborative effort is required to study these molecular characteristics in order to generate a genetic panel with clinical utility. PMID:25452763

Objectives Magnetic resonance imaging (MRI)-guided high intensity focused ultrasound surgery (MRgFUS) is a newly emerging non-invasive technique for the treatment of uterine fibroids. The purpose of this study is to review the clinical impact of MRgFUS. Methods This study examined 157 patients. The high intensity focused ultrasound (HIFU) utilized in this study was Philips Achieva 1.5 Tesla MR (Philips Healthcare, Best, the Netherlands) and Sonalleve HIFU system. The patients were followed in post-operative Month 1, Month 3, and Month 6 to investigate any change. Then, these were further classified according to the use of uterine stimulant (oxytocin) in parallel, Funaki Type of uterine fibroid, HIFU intensity, and non-perfused volume (NPV) ratio. Results When the uterine stimulant was utilized, the HIFU intensity was measured at significantly lower levels, compared with the group not using uterine stimulant, and treatment duration was significantly. The NPV ratio was found significantly higher in the group using uterine stimulant. Concerning the correlation between Funaki Type of uterine fibroid and average sonication power, it was found that the closer to Type I, the lower the sonication power, the shorter the treatment duration, and the higher the NPV ratio significantly. Conclusions In this study, it was found that the lower the Funaki Types of uterine fibroids, and the higher the NPV ratio immediately after the operation, the larger the uterine fibroid volume decrease and SSS change were. Also, if uterine stimulant was used in parallel in treatment, treatment duration and HIFU intensity could become shorter and lower. PMID:27617244

Students' motivational beliefs in science learning, school motivational contexts, and science achievement in Taiwan

NASA Astrophysics Data System (ADS)

Wang, Cheng-Lung; Liou, Pey-Yan

2017-05-01

Taiwanese students are featured as having high academic achievement but low motivational beliefs according to the serial results of the Trends in Mathematics and Science Study (TIMSS). Moreover, given that the role of context has become more important in the development of academic motivation theory, this study aimed to examine the relationship between motivational beliefs and science achievement at both the student and school levels. Based on the Expectancy-Value Theory, the three motivational beliefs, namely self-concept, intrinsic value, and utility value, were the focuses of this study. The two-level hierarchical linear model was used to analyse the Taiwanese TIMSS 2011 eighth-grade student data. The results indicated that each motivational belief had a positive predictive effect on science achievement. Additionally, a positive school contextual effect of self-concept on science achievement was identified. Furthermore, school-mean utility value had a negative moderating effect on the relationship between utility value and science achievement. In conclusion, this study sheds light on the functioning of motivational beliefs in science learning among Taiwanese adolescents with consideration of the school motivational contexts.

Previous field studies utilizing solid-phase microextraction (SPME) predominantly focused on volatile and semivolatile compounds in air or water. Earlier in vivo sampling studies utilizing SPME were limited to the liquid matrix (blood). The present study has expanded the SPME technique to semisolid tissues under laboratory and field conditions through the investigation of both theoretical and applied experimental approaches. Pre-equilibrium extraction and desorption were performed in vivo in two separate animals. Excellent linearity was found between the amounts extracted by SPME from the muscle of living fish and the waterborne concentrations of pharmaceuticals. A simple SPME method is also described to simultaneously determine free and total analyte concentrations in living tissue. The utility of in vivo SPME sampling was evaluated in wild fish collected from a number of different river locations under varying degrees of influence from municipal wastewater effluents. Diphenhydramine and diltiazem were detected in the muscle of fish downstream of a local wastewater treatment plant. Based on this study, SPME demonstrated several important advantages such as simplicity, sensitivity, and robustness under laboratory and in vivo field sampling conditions.

Rosman, David A; Duszak, Richard; Wang, Wenyi; Hughes, Danny R; Rosenkrantz, Andrew B

2018-02-01

The objective of our study was to use a new modality and body region categorization system to assess changing utilization of noninvasive diagnostic imaging in the Medicare fee-for-service population over a recent 20-year period (1994-2013). All Medicare Part B Physician Fee Schedule services billed between 1994 and 2013 were identified using Physician/Supplier Procedure Summary master files. Billed codes for diagnostic imaging were classified using the Neiman Imaging Types of Service (NITOS) coding system by both modality and body region. Utilization rates per 1000 beneficiaries were calculated for families of services. Among all diagnostic imaging modalities, growth was greatest for MRI (+312%) and CT (+151%) and was lower for ultrasound, nuclear medicine, and radiography and fluoroscopy (range, +1% to +31%). Among body regions, service growth was greatest for brain (+126%) and spine (+74%) imaging; showed milder growth (range, +18% to +67%) for imaging of the head and neck, breast, abdomen and pelvis, and extremity; and showed slight declines (range, -2% to -7%) for cardiac and chest imaging overall. The following specific imaging service families showed massive (> +100%) growth: cardiac CT, cardiac MRI, and breast MRI. NITOS categorization permits identification of temporal shifts in noninvasive diagnostic imaging by specific modality- and region-focused families, providing a granular understanding and reproducible analysis of global changes in imaging overall. Service family-level perspectives may help inform ongoing policy efforts to optimize imaging utilization and appropriateness.

Regulatory Focus Affects Physician Risk Tolerance

Veazie, Peter J.; McIntosh, Scott; Chapman, Benjamin P.; Dolan, James G.

2014-01-01

Risk tolerance is a source of variation in physician decision-making. This variation, if independent of clinical concerns, can result in mistaken utilization of health services. To address such problems, it will be helpful to identify nonclinical factors of risk tolerance, particularly those amendable to intervention – regulatory focus theory suggests such a factor. This study tested whether regulatory focus affects risk tolerance among primary care physicians. Twenty-seven primary care physicians were assigned to promotion-focused or prevention-focused manipulations and compared on the Risk Taking Attitudes in Medical Decision Making scale using a randomization test. Results provide evidence that physicians assigned to the promotion-focus manipulation adopted an attitude of greater risk tolerance than the physicians assigned to the prevention-focused manipulation (P=0.01). The Cohen’s d statistic was conventionally large at 0.92. Results imply that situational regulatory focus in primary care physicians affects risk tolerance and may thereby be a nonclinical source of practice variation. Results also provide marginal evidence that chronic regulatory focus is associated with risk tolerance (P=0.05), but the mechanism remains unclear. Research and intervention targeting physician risk tolerance may benefit by considering situational regulatory focus as an explanatory factor. PMID:25431799

Introduction We assess the relationship between race and orthodontic service utilization for Medicaid-enrolled children. Methods This cross-sectional study focused on 570,364 Washington Medicaid-enrolled children ages 6-19 years. The main predictor variable was self-reported race (White versus non-White). The outcome variable was orthodontic service utilization, defined as children who were pre-authorized for orthodontic treatment by Medicaid in 2012 and subsequently received orthodontic records and initiated treatment. Logistic regression models were used to test the hypothesis that non-Whites would be less likely to utilize orthodontic care than Whites. Results A total of 8,223 children were approved by Medicaid for orthodontic treatment and 7,313 received records and initiated treatment. Non-Whites were significantly more likely to utilize orthodontic care than Whites (Odds Ratio [OR]=1.18; 95% confidence interval [CI]=1.02, 1.36; p=.031). Hispanic non-White children were more likely to utilize orthodontic care than non-Hispanic White children (OR=1.42; 95% CI=1.18, 1.70; p<.001). Conclusion In 2012, non-White children in Washington Medicaid were significantly more likely to utilize orthodontic care than White children. The Washington Medicaid program demonstrates a potential model for addressing racial disparities in orthodontic service utilization. Future research should identify mechanisms underlying these findings and continue to monitor orthodontic service utilization for minority children in Medicaid. PMID:27021456

In previous longitudinal studies of mortality and morbidity among foreign-born and native-born Swedes, increased mortality and dissimilarities in mortality pattern were found. The aim of this study is to describe, compare, and analyse the utilization of in-hospital care among deceased foreign- and Swedish-born persons during the years 1987–1999 with focus on four diagnostic categories. The study population consisted of 361,974 foreign-born persons aged 16 years and upward who were registered as living in Sweden in 1970, together with 361,974 matched Swedish controls for each person. Data from Statistics Sweden (SCB) and the National Board of Health and Welfare Centre for Epidemiology, covering the period 1970–1999, was used. Persons were selected if they were admitted to hospital during 1987–1999 and the cause of death was in one of four ICD groups. The results indicate a tendency towards less health care utilization among migrants, especially men, as regards Symptoms, signs, and ill-defined conditions and Injury and poisoning. Further studies are needed to explore the possible explanations and the pattern of other diseases to see whether migrants, and especially migrant men, are a risk group with less utilization of health care.

Nelson, Arif Z.; Ewoldt, Randy H.

2017-11-01

Design in fluid mechanics often focuses on optimizing geometry (airfoils, surface textures, microfluid channels), but here we focus on designing fluids themselves. The dramatically shear-thinning ``yield-stress fluid'' is currently the most utilized non-Newtonian fluid phenomenon. These rheologically complex materials, which undergo a reversible transition from solid-like to liquid-like fluid flow, are utilized in pedestrian products such as paint and toothpaste, but also in emerging applications like direct-write 3D printing. We present a paradigm for yield-stress fluid design that considers constitutive model representation, material property databases, available predictive scaling laws, and the many ways to achieve a yield stress fluid, flipping the typical structure-to-rheology analysis to become the inverse: rheology-to-structure with multiple possible materials as solutions. We describe case studies of 3D printing inks and other flow scenarios where designed shear-thinning enables performance remarkably beyond that of Newtonian fluids. This work was supported by Wm.

How can transcranial magnetic stimulation be used to causally manipulate memory representations in the human brain?

PubMed

Widhalm, Morgan L; Rose, Nathan S

2018-06-27

We present a focused review on the utility of transcranial magnetic stimulation (TMS) for modulating memory, with a particular focus on multimodal approaches in which TMS is paired with neuroimaging methods (electroencephalography and magnetic resonance imaging (MRI)) to manipulate and measure working memory processes. We contrast the utility of TMS for manipulating memory with other forms of noninvasive brain stimulation, as well as different forms of TMS including single-pulse, paired-pulse and repetitive TMS protocols. We discuss the potential for TMS to address fundamental cognitive neuroscience questions about the nature of memory processes and representations, while acknowledging the considerable variability of behavioral and neural outcomes in TMS studies. Also discussed are the limitations of this technology, current advancements that have helped to defray the impact of these limitations, and suggestions for future directions in research and methodology.

Pain assessment and management in end of life care: a survey of assessment and treatment practices of hospice music therapy and nursing professionals.

PubMed

Groen, Kara Mills

2007-01-01

The primary focus of this paper is to describe current trends in pain assessment in end of life care with a secondary focus on music therapy techniques commonly used to address pain for hospice patients. These trends were determined through a survey of 72 board certified music therapists and 92 hospice and palliative nurses. Survey results indicate that most music therapists in the hospice setting incorporate formal pain assessment into their practice; both nursing professionals and music therapists surveyed utilize multiple assessment tools to assess patient pain. Although there are currently a variety of pain assessment tools used, this study indicates that nursing professionals most frequently use the Numerical Rating Scale (NRS) and FACES scales, and identified them as appropriate for use by nonnursing members of the interdisciplinary hospice team. This paper also describes music therapy techniques most often utilized by music therapists with hospice patients to address acute and chronic pain symptoms.

Objective To document the prospective, reciprocal relationships among substance use problems, utilization of drug treatment, and predisposing beliefs thought to increase treatment utilization. Data Source Persistent Effects of Treatment Study-Adolescent (PETS-A), conducted by the Center on Substance Abuse Treatment. This was a longitudinal study of youths originally participating in one of two CSAT studies; one sample included 476 youths receiving residential drug treatment, and the other included 519 youths receiving outpatient treatment. Study Design This study uses five waves of data collected over a 12-month period to examine the temporal relationships among four variables: treatment dose, substance use problems, drug resistance self-efficacy, and perceived need for treatment (PNT). Data from this longitudinal study were analyzed using cross-lagged panel models, and structural equation modeling techniques were used to estimate the prospective, reciprocal relationships among these four variables in each of the two samples, while controlling for several covariates. Principal Findings Both PNT and low drug resistance self-efficacy led to higher levels of subsequent treatment. However, low self-efficacy presaged increases in drug problems while PNT predicted decreases. Conclusions Understanding the role of psychological variables in the utilization of health services is complicated for psychological disorders because beliefs that affect treatment can also influence the disorder itself. Efforts to keep adolescents in drug treatment should focus on convincing youth that treatment can help them with their problems, rather than convincing them that they cannot resist drugs on their own. While both messages increase treatment utilization, the latter belief undermines the effects of treatment. PMID:16033496

Despite widespread adoption of patient feedback surveys in international health-care systems, including the English NHS, evidence of a demonstrable impact of surveys on service improvement is sparse. To explore the views of primary care practice staff regarding the utility of patient experience surveys. Qualitative focus groups. Staff from 14 English general practices. Whilst participants engaged with feedback from patient experience surveys, they routinely questioned its validity and reliability. Participants identified surveys as having a number of useful functions: for patients, as a potentially therapeutic way of getting their voice heard; for practice staff, as a way of identifying areas of improvement; and for GPs, as a source of evidence for professional development and appraisal. Areas of potential change stimulated by survey feedback included redesigning front-line services, managing patient expectations and managing the performance of GPs. Despite this, practice staff struggled to identify and action changes based on survey feedback alone. Whilst surveys may be used to endorse existing high-quality service delivery, their use in informing changes in service delivery is more challenging for practice staff. Drawing on the Utility Index framework, we identified concerns relating to reliability and validity, cost and feasibility acceptability and educational impact, which combine to limit the utility of patient survey feedback. Feedback from patient experience surveys has great potential. However, without a specific and renewed focus on how to translate feedback into action, this potential will remain incompletely realized. © 2014 The Authors Health Expectations Published by John Wiley & Sons Ltd.

Background and Purpose Acute stroke education has focused on stroke symptom recognition. Lack of education about stroke preparedness and appropriate actions may prevent people from seeking immediate care. Few interventions have rigorously evaluated preparedness strategies in multiethnic community settings. Methods The Acute Stroke Program of Interventions Addressing Racial and Ethnic Disparities (ASPIRE) project is a multi-level program utilizing a community engaged approach to stroke preparedness targeted to underserved black communities in the District of Columbia (DC). This intervention aimed to decrease acute stroke presentation times and increase intravenous tissue plasminogen activator (IV tPA) utilization for acute ischemic stroke. Results Phase 1 included: 1) enhancement of EMS focus on acute stroke; 2) hospital collaborations to implement and/or enrich acute stroke protocols and transition DC hospitals toward Primary Stroke Center certification; and 3) pre-intervention acute stroke patient data collection in all 7 acute care DC hospitals. A community advisory committee, focus groups, and surveys identified perceptions of barriers to emergency stroke care. Phase 2 included a pilot intervention and subsequent citywide intervention rollout. A total of 531 community interventions were conducted with over 10,256 participants reached; 3289 intervention evaluations were performed, and 19,000 preparedness bracelets and 14,000 stroke warning magnets were distributed. Phase 3 included an evaluation of EMS and hospital processes for acute stroke care and a yearlong post-intervention acute stroke data collection period to assess changes in IV tPA utilization. Conclusions We report the methods, feasibility, and pre-intervention data collection efforts of the ASPIRE intervention. PMID:24876243

Electric vehicle utilization for ancillary grid services

Electric vehicle has been developed through several decades as transportation mean, without paying sufficient attention of its utilization for other purposes. Recently, the utilization of electric vehicle to support the grid electricity has been proposed and studied intensively. This utilization covers several possible services including electricity storage, spinning reserve, frequency and voltage regulation, and emergency energy supply. This study focuses on theoretical and experimental analysis of utilization of electric vehicles and their used batteries to support a small-scale energy management system. Charging rate of electric vehicle under different ambient temperature (seasonal condition) is initially analyzed to measure the correlation of charging rate, charging time, and state-of-charge. It is confirmed that charging under warmer condition (such as in summer or warmer region) shows higher charging rate than one in colder condition, therefore, shorter charging time can be achieved. In addition, in the demonstration test, each five electric vehicles and used batteries from the same electric vehicles are employed and controlled to support the electricity of the office building. The performance of the system is evaluated throughout a year to measure the load leveling effect during peak-load time. The results show that the targeted peak-load can be shaved well under certain calculated peak-shaving threshold. The finding confirms that the utilization of electric vehicle for supporting the electricity of grid or certain energy management system is feasible and deployable in the future.

Levers supporting tariff growth for water services: evidence from a contingent valuation analysis.

Guerrini, Andrea; Vigolo, Vania; Romano, Giulia; Testa, Federico

2018-02-01

The backwardness of the water utilities sector necessitates urgent investment in infrastructure to improve water quality and efficiency in water supply networks. A policy of tariff growth represents the main source to sustain such investments. Therefore, customer engagement in the form of willingness to pay (WTP) is highly desirable by water utilities to obtain social legitimization and support. This study examines the determinants of consumers' WTP for improvement programs for three drinking water issues: quality of water sources, renewal of water mains, and building of new wastewater treatment plants. The study is based on a survey conducted among a sample of 587 customers of a water utility located in the province of Verona in the north of Italy. The contingence valuation method is used to measure WTP. Specifically, an ordinal logistic regression model yields the following significant determinants of WTP: quality of water and services provided, preference for privatization of the water utility, sustainable consumption of water, and some socio-demographic variables. The findings provide interesting insights into the drivers of WTP as well as managerial recommendations for water utilities. In particular, the findings show that water utilities need to improve service and water quality to increase customers' acceptance of tariff growth. In addition, utilities should invest in customer education and communication activities focusing on specific age groups (e.g., older customers) to enhance their WTP. Finally, communication strategies should reinforce the possible role of liberalization and privatization in supporting infrastructure investments. Copyright © 2017 Elsevier Ltd. All rights reserved.

Background UNAIDS has set a new target 90-90-90 by 2020. To achieve this target, current programs need to address challenges that limit access, availability, and utilization of HIV testing and treatment services. Therefore, the aim of this study was to identify the barriers that influence access, availability, and utilization of HIV services in rural Uganda within the setting of a large donor funded program. Methods We conducted key informant interviews with stakeholders at the district level, staff of existing HIV/AIDS projects, and health facilities in 19 districts. Data were also collected from focus group discussions comprised of clients presenting for HIV care and treatment. Data were transcribed and analyzed using content analysis. Results. Barriers identified were as follows: (1) drug shortages including antiretroviral drugs at health facilities. Some patients were afraid to start ART because of worrying about shortages; (2) distance and (3) staffing shortages; (4) stigma persistence; (5) lack of social and economic support initiatives that enhance retention in treatment. Conclusions In conclusion, our study has identified several factors that influence access, availability, and utilization of HIV services. Programs need to address drug and staff shortages, HIV stigma, and long distances to health facilities to broaden access and utilization in order to realize the UNAIDS target. PMID:29750175

Patient feedback is considered important for healthcare organizations. However, measurement and analysis of patient reported data is useful only if gathered insights are transformed into actions. This article focuses on gathering and utilization of patient experience data at hospitals with the aim of supporting the development of patient-centered services. The study was designed to explore both current practices of collecting and utilizing patient feedback at hospitals as well as future feedback-related opportunities. Nine people working at different hierarchical levels of three university hospitals in Finland participated in in-depth interviews. Findings indicate that current feedback processes are poorly planned and inflexible. Some feedback data are gathered, but not systematically utilized. Currently, it is difficult to obtain a comprehensive picture of the situation. One future hope was to increase the amount of patient feedback to be able to better generalize and utilize the data. Based on the findings the following recommendations are given: attention to both patients' and healthcare staff's perspectives when collecting feedback, employing a coordinated approach for collecting and utilizing patient feedback, and organizational transformation towards a patient-centric culture.

To assess use, utility and impact of transition interventions designed to support and empower self-management in youth with chronic health conditions during transition into adult healthcare. A 4-year mixed-method prospective cohort study. 2 academic paediatric hospitals (13 clinics) in Canada. 50 adolescents (42% male; mean age 17.9±0.9 years; 20 underlying diagnoses) with transfer to adult care planned within 1 year. The Youth KIT (an organisational tool that includes goal setting activities); an online transition mentor. Frequency of use, utility and impact of the transition interventions; goal achievement; post-transfer qualitative interviews with youth. 50 participants were enrolled during their last year of paediatric care; 36 (72%) were followed into adult care. All participants had access to the transition interventions from enrolment until the end of the study (exposure time: 12-47 months). Most youth (85%) reported using the medical/health section of the Youth KIT at least once; 20 (40%) participants engaged in chats with the mentor. The overall perceived utility of both interventions was modest; the Youth KIT received the highest ratings for 'help with goal setting': (mean (SD): 4.2 (2.3)) on a 7-point Likert scale. 45 (90%) participants set 294 transition goals. Goal achievement performance and satisfaction increased over time (p≤0.001). The qualitative evidence revealed reasons behind the variability in use and utility of the interventions, the interconnectedness of life-course and healthcare transitions, and the need for stronger partnerships between paediatric and adult healthcare systems. Participants' perceptions about the utility of the Youth KIT and the online mentor were modest. Transition supports need to be carefully tailored, timed and integrated into healthcare systems. Individualised goal setting may be an important 'active ingredient' in optimising transition supports and outcomes. Interventions that focus on youth only are insufficient for empowering self-management. Published by the BMJ Publishing Group Limited.

Maturing markets and the accompanying increase in competition, sophistication of customers, and differentiation of products and services have forced companies to focus their marketing efforts on segments in which they can prosper. The experience in these companies has revealed that market segmentation, although simple in concept, is not so easily implemented. It is reasonable to anticipate substantial benefits from additional market segmentation within each of the classes traditionally distinguished in the industry - residential, commercial, and industrial. Segmentation is also likely to prove useful for utilities facing quite different marketing environments, e.g., in terms of demand patterns (number of customers,more » winter- and summer-peaking, etc.), capacity, and degree of regulatory and competitive pressures. Within utilities, those charged with developing and implementing segmentation strategies face some difficult issues. The primary objective of this monograph is to provide some answers to these questions. This monograph is intended to provide utility researchers with a guide to the design and execution of market segmentation research in utility markets. Several composite cases, drawn from actual studies conducted by electric utilities, are used to illustrate the discussion.« less

A review of patient-centred post-fracture interventions in the context of theories of health behaviour change.

The purpose of this literature review is to determine whether and to what extent current post-fracture osteoporosis interventions utilize theories of health behaviour change and whether those that are theory-based are more successful in producing desired behaviour changes. Studies were identified by applying additional criteria to the final selection stage of a systematic review of non-surgical osteoporosis interventions in the orthopaedic environment. We identified 42 primary studies targeted at patients and improving post-fracture osteoporosis care. As well as describing the studies (in terms of design, population, interventions, outcomes), we focused on theoretical framework and elements of behaviour change models. The 42 studies included in this review utilized a variety of post-fracture interventions; however, none of them reported using an underlying theoretical base. Only three studies drew on what we felt to be elements of a theoretical framework. The lack of theoretically based studies points to a currently under-utilized area of behaviour change research that could be applied to post-fracture interventions in order to make them more effective. Despite an abundance of literature supporting theories of behaviour change, post-fracture osteoporosis interventions do not report utilizing these theories. Theories of behaviour change could be applied to post-fracture osteoporosis interventions to explain why patients initiate osteoporosis management. Future research should explore the application of theories of health behaviour change to post-fracture interventions.

Abstract Background: Understanding the characteristics of high and low utilizers of smartphone applications (apps) for smoking cessation would inform development of more engaging and effective apps, yet no studies to date have addressed this critical question. Informed by prior research on predictors of cessation Web site utilization, this study examines the degree to which baseline demographic factors (gender, age, and education), smoking-related factors (smoking level and friends' smoking), and psychological factors (depression and anxiety) are predictive of utilization of a smartphone app for smoking cessation called SmartQuit. Materials and Methods: Data came from 98 participants randomized to SmartQuit as part of a pilot trial from March to May 2013. We used negative binomial count regressions to examine the relationship between user characteristics and utilization of the app over an 8-week treatment period. Results: Lower education (risk ratio [RR]=0.492; p=0.021), heavier smoking (RR=0.613; p=0.033), and depression (RR=0.958; p=0.017) prospectively predicted lower app utilization. Women (RR=0.320; p=0.022), those with lower education (RR=0.491; p=0.013), and heavier smokers (RR=0.418; p=0.039) had lower utilization of app features known to predict smoking cessation. Conclusions: Many of the predictors of utilization of smoking cessation apps are the same as those of cessation Web sites. App-delivered smoking cessation treatment effectiveness could be enhanced by focusing on increasing engagement of women, those with lower education, heavy smokers, and those with current depressive symptoms.

This study aimed to develop a near-patient, e-learning tool and explore student views on how utilization of such a tool influenced their learning. Third year medical students from Monash University in Melbourne, Australia were invited to trial a novel, near-patient, e-learning tool in two separate pilots within the ward environment. All participating students were invited to contribute to focus groups which were audio-recorded, transcribed verbatim and thematically analyzed. Four focus groups were conducted with a total of 17 participants. The emerging themes revealed influences on the students' learning both prior to and during a clinical encounter, as well as following completion of an e-learning module. The unifying concept which linked all six themes and formed the central feature of the experience was patient-centered learning. This occurred through the acquisition of contextualized knowledge and the facilitation of workplace integration. Utilization of a near-patient e-learning tool influences medical student learning in a number of complex, inter-related ways. Clinical e-learning tools are poised to become more commonplace and provide many potential benefits to student learning. However, incorporation of technology into clinical encounters requires specific skills which should form an integral part of primary medical training.

Hospitalized adult Medicaid recipients with chronic disease are at risk for rehospitalization within 90 days of discharge, but most research has focused on the Medicare population. The purpose of this study is to examine the impact of population-based care management intensity on inpatient readmissions in Medicaid adults with pre-existing chronic disease. Retrospective analyses of 2,868 index hospital admissions from 2012 New York State Medicaid Data Warehouse claims compared 90-day post-discharge utilization in populations with and without transitional care management interventions. High intensity managed care organization interventions were associated with higher outpatient and lower emergency department post-discharge utilization than low intensity fee-for-service management. However, readmission rates were higher for the managed care cases. Shorter time to readmission was associated with managed care, diagnoses that include heart and kidney failure, shorter length of stay for index hospitalization, and male sex; with no relationship to age. This unexpected result flags the need to re-evaluate readmission as a quality indicator in the complex Medicaid population. Quality improvement efforts should focus on care continuity during transitions and consider population-specific factors that influence readmission. Optimum post-discharge utilization in the Medicaid population requires a balance between outpatient, emergency and inpatient services to improve access and continuity.

Analysis of phase conjugation in a turbid medium

The ability to focus light in most tissue degrades quickly with depth due to high optical scattering. Recently, researchers have found they can concentrate light tightly despite these scattering effects by using a guidestar and optical phase conjugation to focus light to greater distances in tissue. An optical or probe signal is transmitted through a scattering medium and its resulting wavefront is detected. The wavefront is then conjugated and utilized as a new optical source or delivery wave that focuses back to the guidestar's location with minimal scattering. The power in the delivery wave may be greatly increased for enhanced energy delivery at the focus. Modulation by an ultrasound (US) beam may be utilized to generate the guidestar dynamically and allow for US-resolution at depths of several millimeters. The delivery wave is successful at focusing light back at the guidestar because it creates constructive interference at the desired focus. However, if the phases of the field contributions change, we expect the delivered power at the focus to be reduced. This paper will analyze the robustness of this method when the probe beam is at one wavelength and the delivery wave is at another. This will allow us to characterize the deleterious effects of varying the phase contributions at the focus.

Traditional still cameras can only focus on a single plane for each image while rendering everything outside of that plane out of focus. However, new light-field imaging technology makes it possible to adjust the focus plane after an image has already been captured. This technology allows the viewer to interactively explore an image with objects and anatomy at varying depths and clearly focus on any feature of interest by selecting that location during post-capture viewing. These images with adjustable focus can serve as valuable educational tools for neurosurgical residents. We explore the utility of light-field cameras and review their strengths and limitations compared to other conventional types of imaging. The strength of light-field images is the adjustable focus, as opposed to the fixed-focus of traditional photography and video. A light-field image also is interactive by nature, as it requires the viewer to select the plane of focus and helps with visualizing the three-dimensional anatomy of an image. Limitations include the relatively low resolution of light-field images compared to traditional photography and video. Although light-field imaging is still in its infancy, there are several potential uses for the technology to complement traditional still photography and videography in neurosurgical education.

2015-05-01

The need for advanced techniques to detect improvised explosive devices (IED) at stand-off distances greater than ten (10) meters has driven AMI Research and Development (AMI) to develop a solution to detect and identify the threat utilizing a forward looking Synthetic Aperture Radar (SAR) combined with our CW radar technology Nuclear Quadrupole Resonance (NQR) detection system. The novel features include a near-field sub-wavelength focusing antenna, a wide band 300 KHz to 300 MHz rapidly scanning CW radar facilitated by a high Q antenna/tuner, and an advanced processor utilizing Rabi transitions where the nucleus oscillates between states under the time dependent incident electromagnetic field and alternately absorbs energy from the incident field while emitting coherent energy via stimulated emission. AMI's Sub-wavelength Focusing Wide Band Super Lens uses a Near-Field SAR, making detection possible at distances greater than ten (10) meters. This super lens is capable of operating on the near-field and focusing electromagnetic waves to resolutions beyond the diffraction limit. When applied to the case of a vehicle approaching an explosive hazard the methodologies of synthetic aperture radar is fused with the array based super resolution and the NQR data processing detecting the explosive hazard.

Focus group data were generated by a larger, mixed-methods investigation on treatment practices among therapists working with significantly traumatized populations in a primarily rural, underdeveloped region of the USA. This paper explores reasons behind low utilization of evidence-based practices (EBPs) that putatively would benefit poor communities where these behavioural health care providers serve. Eight focus groups of 45 licensed and certified behavioural health professionals were conducted over a 6-month period of time in 2006. Sites were selected based on Beale code designations with representation from urban, rural, and rural with urban influence providers. Potential respondents were selected from licensing board membership rosters and invited to participate in the study. Focus groups were facilitated by trained interviewers using a semi-structured interview schedule that focused on how participants defined, assessed, and understood trauma, as well as the information therapists utilized to determine interventions for clients with trauma histories. Focus group transcripts were analysed using qualitative data reduction methods and six major themes emerged regarding the limited use of EBPs: complexity of trauma identification, issues with manualized assessment, role of treatment settings, conditions for innovation success and failure, untangling cultural effects, and defining successful treatment outcomes. These findings shed light on the endurance of insufficient behavioural health infrastructures despite therapists' access to scientifically validated treatments for trauma spectrum and co-morbid mental disorders suffered by children and adults. Such insights have implications for the success of global dissemination of validated behavioural health interventions. © 2010 Blackwell Publishing Ltd.

The objective of this research project was to develop a second generation duct sorbent injection technology as a cost-effective compliance option for the 1990 Clean Air Act Amendments. Research and development work was focused on the Advanced Coolside process, which showed the potential for exceeding the original performance targets of 90% SO{sub 2} removal and 60% sorbent utilization. Process development was conducted in a 1000 acfm pilot plant. The pilot plant testing showed that the Advanced Coolside process can achieve 90% SO{sub 2} removal at sorbent utilizations up to 75%. The testing also showed that the process has the potentialmore » to achieve very high removal efficiency (90 to >99%). By conducting conceptual process design and economic evaluations periodically during the project, development work was focused on process design improvements which substantially lowered process capital and operating costs, A final process economic study projects capital costs less than one half of those for limestone forced oxidation wet FGD. Projected total SO{sub 2} control cost is about 25% lower than wet FGD for a 260 MWe plant burning a 2.5% sulfur coal. A waste management study showed the acceptability of landfill disposal; it also identified a potential avenue for by-product utilization which should be further investigated. Based on the pilot plant performance and on the above economic projections, future work to scale up the Advanced Coolside process is recommended.« less

The renal medullary thick ascending limb (mTAL) of the Dahl salt-sensitive (SS) rat is the site of enhanced NaCl reabsorption and excess superoxide production. In the present studies we isolated mitochondria from mTAL of SS and salt-resistant control strain SS.13BN rats on 0.4 and 8% salt diet for 7 days and performed a proteomic analysis. Purity of mTAL and mitochondria isolations exceeded 93.6 and 55%, respectively. Using LC/MS spectral analysis techniques we identified 96 mitochondrial proteins in four biological mTAL mitochondria samples, run in duplicate, as defined by proteins with a false discovery rate <5% and scan count ≥2. Seven of these 96 proteins, including IDH2, ACADM, SCOT, Hsp60, ATPA, EFTu, and VDAC2 were differentially expressed between the two rat strains. Oxygen consumption and high-resolution respirometry analyses showed that mTAL cells and the mitochondria in the outer medulla of SS rats fed high-salt diet exhibited lower rates of oxygen utilization compared with those from SS.13BN rats. These studies advance the conventional proteomic paradigm of focusing exclusively upon whole tissue homogenates to a focus upon a single cell type and specific subcellular organelle. The results reveal the importance of a largely unexplored role for deficiencies of mTAL mitochondrial metabolism and oxygen utilization in salt-induced hypertension and renal medullary oxidative stress.

To document the prospective, reciprocal relationships among substance use problems, utilization of drug treatment, and predisposing beliefs thought to increase treatment utilization. Persistent Effects of Treatment Study-Adolescent (PETS-A), conducted by the Center on Substance Abuse Treatment. This was a longitudinal study of youths originally participating in one of two CSAT studies; one sample included 476 youths receiving residential drug treatment, and the other included 519 youths receiving outpatient treatment. This study uses five waves of data collected over a 12-month period to examine the temporal relationships among four variables: treatment dose, substance use problems, drug resistance self-efficacy, and perceived need for treatment (PNT). Data from this longitudinal study were analyzed using cross-lagged panel models, and structural equation modeling techniques were used to estimate the prospective, reciprocal relationships among these four variables in each of the two samples, while controlling for several covariates. Both PNT and low drug resistance self-efficacy led to higher levels of subsequent treatment. However, low self-efficacy presaged increases in drug problems while PNT predicted decreases. Understanding the role of psychological variables in the utilization of health services is complicated for psychological disorders because beliefs that affect treatment can also influence the disorder itself. Efforts to keep adolescents in drug treatment should focus on convincing youth that treatment can help them with their problems, rather than convincing them that they cannot resist drugs on their own. While both messages increase treatment utilization, the latter belief undermines the effects of treatment.

2016-01-01

This paper investigates the optimal weight for both male and female using energy imbalance and utility maximization. Based on the difference of energy intake and expenditure, we develop a state equation that reveals the weight gain from this energy gap. We ​construct an objective function considering food consumption, eating habits and survival rate to measure utility. Through applying mathematical tools from optimal control methods and qualitative theory of differential equations, we obtain some results. For both male and female, the optimal weight is larger than the physiologically optimal weight calculated by the Body Mass Index (BMI). We also study the corresponding trajectories to steady state weight respectively. Depending on the value of a few parameters, the steady state can either be a saddle point with a monotonic trajectory or a focus with dampened oscillations.

Background Atrial fibrillation (AF) is associated with increased risk of hospitalization. Little is known about the impact of AF on utilization of noninpatient health care or about sex or race differences in AF‐related utilization. We examined rates of inpatient and outpatient utilization by AF status in the Atherosclerosis Risk in Communities study. Methods and Results Participants with incident AF enrolled in fee‐for‐service Medicare for at least 12 continuous months between 1991 and 2009 (n=932) were matched on age, sex, race and field center with up to 3 participants without AF (n=2729). Healthcare utilization was ascertained from Medicare claims and classified by primary International Classification of Diseases, ninth revision code. The average annual numbers of days hospitalized were 13.2 (95% CI 11.6 to 15.0) and 2.8 (95% CI 2.5 to 3.1) for those with and without AF, respectively. The corresponding numbers of annual outpatient claims were 53.3 (95% CI 50.5 to 56.3) and 22.9 (95% CI 22.1 to 23.8) for those with and without AF, respectively. Most utilization among AF patients was attributable to non‐AF conditions. The adjusted rate ratio for annual days hospitalized for other cardiovascular disease–related reasons was 4.58 (95% CI: 3.41 to 6.16) for those with AF versus those without AF. The association between AF and healthcare utilization was similar among men and women and among white and black participants. Conclusions Participants with AF had considerably greater healthcare utilization, and the difference in utilization for other cardiovascular disease–related reasons was substantial. In addition to rate or rhythm treatment, AF management should focus on the accompanying cardiovascular comorbidities. PMID:25359400

With the advent of healthcare payment reform, identifying high-risk populations has become more important to providers. Existing risk-prediction models often focus on chronic conditions. This study sought to better understand other factors to improve identification of the highest risk population. A retrospective cohort study of a paneled primary care population utilizing 2010 data to calibrate a risk prediction model of hospital and emergency department (ED) use in 2011. Data were randomly split into development and validation data sets. We compared the enhanced model containing the additional risk predictors with the Minnesota medical tiering model. The study was conducted in the primary care practice of an integrated delivery system at an academic medical center in Rochester, Minnesota. The study focus was primary care medical home patients in 2010 and 2011 (n = 84,752), with the primary outcome of subsequent hospitalization or ED visit. A total of 42,384 individuals derived the enhanced risk-prediction model and 42,368 individuals validated the model. Predictors included Adjusted Clinical Groups-based Minnesota medical tiering, patient demographics, insurance status, and prior year healthcare utilization. Additional variables included specific mental and medical conditions, use of high-risk medications, and body mass index. The area under the curve in the enhanced model was 0.705 (95% CI, 0.698-0.712) compared with 0.662 (95% CI, 0.656-0.669) in the Minnesota medical tiering-only model. New high-risk patients in the enhanced model were more likely to have lack of health insurance, presence of Medicaid, diagnosed depression, and prior ED utilization. An enhanced model including additional healthcare-related factors improved the prediction of risk of hospitalization or ED visit.

New federal parity and health reform legislation, promising increased behavioral health care access and a focus on prevention, has heightened interest in employee assistance programs (EAPs). This study investigated service utilization by persons with a primary substance use disorder (SUD) diagnosis in a managed behavioral healthcare organization's integrated EAP/managed behavioral health care product (N=1,158). In 2004, 25.0% of clients used the EAP first for new treatment episodes. After initial EAP utilization, 44.4% received no additional formal services through the plan and 40.4% received regular outpatient services. Overall, outpatient care, intensive outpatient/day treatment, and inpatient/residential detoxification were most common. About half of clients had co-occurring psychiatric diagnoses. Mental health service utilization was extensive. Findings suggest that for service users with primary SUD diagnoses in an integrated EAP/MBHC product, the EAP benefit plays a key role at the front end of treatment and is often only one component of treatment episodes.

Functional near-infrared (fNIR) spectroscopy is a promising new technology that has demonstrated utility in the study of normal human cognition. We utilized fNIR spectroscopy to examine the effect of social anxiety and performance on hemodynamic activity in the dorsolateral prefrontal cortex (DLPFC). Socially phobic participants and non-clinical participants with varying levels of social anxiety completed a public speaking task in front of a small virtual audience while the DLPFC was being monitored by the fNIR device. The relationship between anxiety and both blood volume (BV) and deoxygenated hemoglobin (Hb) varied significantly as a function of speech performance, such that individuals with low social anxiety who performed well showed an increase in DLPFC activation relative to those who did not perform well. This result suggests that effortful thinking and/or efficient top-down inhibitory control may have been required to complete an impromptu speech task with good performance. In contrast, good performers who were highly socially anxious showed lower DLPFC activation relative to good performers who were low in social anxiety, suggesting autopilot thinking or less-effortful thinking. In poor performers, slight increases in DLPFC activation were observed from low to highly anxious individuals, which may reflect a shift from effortless thinking to heightened self-focused attention. Heightened self-focused attention, poor inhibitory control resulting in excessive fear or anxiety, or low motivation may lower performance. These results suggest that there can be different underlying mechanisms in the brain that affect the level of speech performance in individuals with varying degrees of social anxiety. This study highlights the utility of the fNIR device in the assessment of changes in DLPFC in response to exposure to realistic phobic stimuli, and further supports the potential utility of this technology in the study of the neurophysiology of anxiety disorders.

This review focuses on risk assessment and prediction tools for bladder cancer (BCa). To review the current knowledge on risk assessment and prediction tools to enhance clinical decision making and counseling of patients with BCa. A literature search in English was performed using PubMed in July 2013. Relevant risk assessment and prediction tools for BCa were selected. More than 1600 publications were retrieved. Special attention was given to studies that investigated the clinical benefit of a prediction tool. Most prediction tools for BCa focus on the prediction of disease recurrence and progression in non-muscle-invasive bladder cancer or disease recurrence and survival after radical cystectomy. Although these tools are helpful, recent prediction tools aim to address a specific clinical problem, such as the prediction of organ-confined disease and lymph node metastasis to help identify patients who might benefit from neoadjuvant chemotherapy. Although a large number of prediction tools have been reported in recent years, many of them lack external validation. Few studies have investigated the clinical utility of any given model as measured by its ability to improve clinical decision making. There is a need for novel biomarkers to improve the accuracy and utility of prediction tools for BCa. Decision tools hold the promise of facilitating the shared decision process, potentially improving clinical outcomes for BCa patients. Prediction models need external validation and assessment of clinical utility before they can be incorporated into routine clinical care. We looked at models that aim to predict outcomes for patients with bladder cancer (BCa). We found a large number of prediction models that hold the promise of facilitating treatment decisions for patients with BCa. However, many models are missing confirmation in a different patient cohort, and only a few studies have tested the clinical utility of any given model as measured by its ability to improve clinical decision making.

The focus is in identifying possibilities of AM in promotion of circular economy and expected environmental benefits based on the found literature. Results of the study indicate significant potential in utilizing AM in repair, refurbishment and remanufacturing activities.

Using HMOs to serve the Medicaid population: what are the effects on utilization and does the type of HMO matter?

Herring, Bradley; Adams, E Kathleen

2011-04-01

States have increasingly used Health Maintenance Organizations (HMOs) to provide medical services to the Medicaid population. However, the effects of these initiatives on total health-care expenses, the mix of utilization, and access to care remain unclear. We examine the effect of changes in Medicaid HMO penetration between 1996 and 2002 on these outcomes using data for the nonelderly Medicaid population in the Community Tracking Study's Household Survey. We develop market-level measures of Medicaid HMO penetration from CMS and InterStudy data, distinguish whether the HMOs specialize in serving the Medicaid population, and use a market fixed-effects model to focus on changes in HMO penetration rates over time. Although limited by imprecise estimates, we find some evidence that utilization and access are related to the market penetration rates of commercial and Medicaid-dominant HMOs, but the pattern of results we observe does not appear to be consistent with welfare improvements.

Plasmonic waveguides with a planar structure exhibit a two-dimensional degree of freedom for the surface plasmon; the degree of freedom can be further reduced by utilizing metallic nanostructures or nanoparticles for surface plasmon resonance. Reduction leads to different lightwave confinement capabilities, which can be utilized to construct plasmonic nanolaser cavities. However, most theoretical and experimental research efforts have focused on planar surface plasmon polariton (SPP) nanolasers. In this study, we combined nanometallic structures intersecting with ZnO nanowires and realized the first laser emission based on pseudowedge SPP waveguides. Relative to current plasmonic nanolasers, the pseudowedge plasmonic lasers reported in our study exhibit extremely small mode volumes, high group indices, high spontaneous emission factors, and high Purell factors beneficial for the strong interaction between light and matter. Furthermore, we demonstrated that compact plasmonic laser arrays can be constructed, which could benefit integrated plasmonic circuits.

Patient medical records today contain vast amount of information regarding patient conditions along with treatment and procedure records. Systematic healthcare resource utilization analysis leveraging such observational data can provide critical insights to guide resource planning and improve the quality of care delivery while reducing cost. Of particular interest to providers are hot spotting: the ability to identify in a timely manner heavy users of the systems and their patterns of utilization so that targeted intervention programs can be instituted, and anomaly detection: the ability to identify anomalous utilization cases where the patients incurred levels of utilization that are unexpected given their clinical characteristics which may require corrective actions. Past work on medical utilization pattern analysis has focused on disease specific studies. We present a framework for utilization analysis that can be easily applied to any patient population. The framework includes two main components: utilization profiling and hot spotting, where we use a vector space model to represent patient utilization profiles, and apply clustering techniques to identify utilization groups within a given population and isolate high utilizers of different types; and contextual anomaly detection for utilization, where models that map patient’s clinical characteristics to the utilization level are built in order to quantify the deviation between the expected and actual utilization levels and identify anomalies. We demonstrate the effectiveness of the framework using claims data collected from a population of 7667 diabetes patients. Our analysis demonstrates the usefulness of the proposed approaches in identifying clinically meaningful instances for both hot spotting and anomaly detection. In future work we plan to incorporate additional sources of observational data including EMRs and disease registries, and develop analytics models to leverage temporal relationships among medical encounters to provide more in-depth insights.

Knowledge diffusion and utilization (KDU) have become a key focus in the health research community because of the limited success to date of research findings to inform health policies, programs and services. Yet, evidence indicates that successful KDU is often predicated on the early involvement of potential knowledge users in the conceptualization and conduct of the research and on the development of a "partnership culture". This study describes the integration of KDU theory with practice via a case study analysis of the Consortium for Applied Research and Evaluation in Mental Health (CAREMH). This qualitative study, using a single-case design, included a number of data sources: proposals, meeting minutes, presentations, publications, reports and curricula vitae of CAREMH members. CAREMH has adopted the following operational strategies to increase KDU capacity: 1) viewing research as a means and not as an end; 2) bringing the university and researcher to the community; 3) using participatory research methods; 4) embracing transdisciplinary research and interactions; and 5) using connectors. Examples of the iterative process between researchers and potential knowledge users in their contribution to knowledge generation, diffusion and utilization are provided. This case study supports the importance of early and ongoing involvement of relevant potential knowledge users in research to enhance its utilization potential. It also highlights the need for re-thinking research funding approaches.

Human-computer interaction is human-centered. An excellent interaction design should focus on the study of user experience, which greatly comes from the consistence between design and human behavioral habit. However, users’ behavioral habits often result from subconsciousness. Therefore, it is smart to utilize users’ subconscious behavior to achieve design's intention and maximize the value of products’ functions, which gradually becomes a new trend in this field.

Optimal Design of Biomass Utilization System for Rural Area Includes Technical and Economic Dimensions

NASA Astrophysics Data System (ADS)

Morioka, Yasuki; Nakata, Toshihiko

In order to design optimal biomass utilization system for rural area, OMNIBUS (The Optimization Model for Neo-Integrated Biomass Utilization System) has been developed. OMNIBUS can derive the optimal system configuration to meet different objective function, such as current account balance, amount of biomass energy supply, and CO2 emission. Most of biomass resources in a focused region e.g. wood biomass, livestock biomass, and crop residues are considered in the model. Conversion technologies considered are energy utilization technologies e.g. direct combustion and methane fermentation, and material utilization technologies e.g. composting and carbonization. Case study in Miyakojima, Okinawa prefecture, has been carried out for several objective functions and constraint conditions. Considering economics of the utilization system as a priority requirement, composting and combustion heat utilization are mainly chosen in the optimal system configuration. However gasification power plant and methane fermentation are included in optimal solutions, only when both biomass energy utilization and CO2 reduction have been set as higher priorities. External benefit of CO2 reduction has large impacts on the system configuration. Provided marginal external benefit of more than 50,000 JPY/t-C, external benefit becomes greater than the revenue from electricity and compost etc. Considering technological learning in the future, expensive technologies such as gasification power plant and methane fermentation will have economic feasibility as well as market competitiveness.
