    Making progress basically, a fundamental issue for the construction companies to get by in a highly competitive industry. From time to time, industry players are facing stiff and tough competition due to large number of players, whether existing or new players involved from various background and track record. Furthermore, the large numbers of component deciding the competitiveness of contractors, whose organization structures and governance have turned out to be more muddled. Different construction companies have their own unique criteria which may differ from one to another. The enormous amount of issues needs to bring down to manageable numbers so that measures can be identified and scrutinized to enhance competitiveness. This paper discusses the result from the critical investigation from past studies in the Asian countries, namely China, India, Thailand, Singapore and Malaysia. Several fundamental factors have been identified as CSFs in construction companies in respective country. Also highlighted a critical survey based upon various literatures written on this subject where critical success factors (CSFs) as a yardstick to gauge the relationship among CSFs in various construction companies in the Asian region. Far reaching estimation of an organization's performance and resulting input to its supervision is crucial for business change. Estimation additionally empowers organizations to be contrasted from one another on the premise of institutionalized data, permitting best practices to be distinguished and connected more widely. Different countries have their own set of critical success factors (CSFs) which may differ in term of priority and at the same time share common elements of success factor in accomplishment as a construction companies. The study, which is exploratory in nature, embraced the content investigation and inductive technique to accomplish its objectives.

    2015-01-01

    Nanoparticles (NPs) show new characteristics compared to the corresponding bulk material. These nanoscale properties make them interesting for various applications in biomedicine and life sciences. One field of application is the use of magnetic NPs to support regeneration in the nervous system. Drug delivery requires a functionalization of NPs with bio-functional molecules. In our study, we functionalized self-made PEI-coated iron oxide NPs with nerve growth factor (NGF) and glial cell-line derived neurotrophic factor (GDNF). Next, we tested the bio-functionality of NGF in a rat pheochromocytoma cell line (PC12) and the bio-functionality of GDNF in an organotypic spinal cord culture. Covalent binding of NGF to PEI-NPs impaired bio-functionality of NGF, but non-covalent approach differentiated PC12 cells reliably. Non-covalent binding of GDNF showed a satisfying bio-functionality of GDNF:PEI-NPs, but turned out to be unstable in conjugation to the PEI-NPs. Taken together, our study showed the importance of assessing bio-functionality and binding stability of functionalized growth factors using proper biological models. It also shows that successful functionalization of magnetic NPs with growth factors is dependent on the used binding chemistry and that it is hardly predictable. For use as therapeutics, functionalization strategies have to be reproducible and future studies are needed. PMID:26388717

    Azarmina, Pejman; Prestwich, Graham; Rosenquist, Joel; Singh, Debbie

    2008-12-01

    Governments and health service providers around the world are under pressure to improve health outcomes while containing rising healthcare costs. In response to such challenges, many regions have implemented services that have been successful in other countries-but 'importing' initiatives has many challenges. This article summarizes factors found to be critical to the success of adapting a US disease management and health promotion programme for use in Italy and the UK. Using three illustrative case studies, it describes how in each region the programme needed to adapt (i) the form and content of the disease management service, (ii) the involvement and integration with local clinicians and services and (iii) the evaluation of programme outcomes. We argue that it is important to implement evidence-based practice by learning lessons from other countries and service initiatives, but that it is equally important to take into consideration the '3Ps' that are critical for successful service implementation: payers, practitioners and patients.

  4. Examination of the relationship between project management critical success factors and project success of oil and gas drilling projects

    NASA Astrophysics Data System (ADS)

    Alagba, Tonye J.

    Oil and gas drilling projects are the primary means by which oil companies recover large volumes of commercially available hydrocarbons from deep reservoirs. These types of projects are complex in nature, involving management of multiple stakeholder interfaces, multidisciplinary personnel, complex contractor relationships, and turbulent environmental and market conditions, necessitating the application of proven project management best practices and critical success factors (CSFs) to achieve success. Although there is some practitioner oriented literature on project management CSFs for drilling projects, none of these is based on empirical evidence, from research. In addition, the literature has reported alarming rates of oil and gas drilling project failure, which is attributable not to technical factors, but to failure of project management. The aim of this quantitative correlational study therefore, was to discover an empirically verified list of project management CSFs, which consistent application leads to successful implementation of oil and gas drilling projects. The study collected survey data online, from a random sample of 127 oil and gas drilling personnel who were members of LinkedIn's online community "Drilling Supervisors, Managers, and Engineers". The results of the study indicated that 10 project management factors are individually related to project success of oil and gas drilling projects. These 10 CSFs are namely; Project mission, Top management support, Project schedule/plan, Client consultation, Personnel, Technical tasks, Client acceptance, Monitoring and feedback, Communication, and Troubleshooting. In addition, the study found that the relationships between the 10 CSFs and drilling project success is unaffected by participant and project demographics---role of project personnel, and project location. The significance of these findings are both practical, and theoretical. Practically, application of an empirically verified CSFs list to oil

    2016-11-01

    Electronics industry is one of the fastest growing industries in the world. In India also, there are high turnovers and growing demand of electronics product especially after post liberalization in early nineties. These products generate e-waste which has become big environmental issue. Industries can handle these e-waste and product returns efficiently by developing reverse logistics (RL) system. A thorough study of critical success factors (CSFs) and their ordered implementation is essential for successful RL implementation. The aim of the study is to review the CSFs, and to prioritize them for RL implementation in Indian electronics industry. Twelve CSFs were identified through literature review, and discussion with the experts from the Indian electronics industry. Fuzzy-Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approach is proposed for prioritizing these CSFs. Perusal of literature indicates that fuzzy-TOPSIS has not been applied earlier for prioritization of CSFs in Indian electronics industry. Five Indian electronics companies were selected for evaluation of this methodology. Results indicate that most of the identified factors are crucial for the RL implementation. Top management awareness, resource management, economic factors, and contracts terms and conditions are top four prioritized factor, and process capabilities and skilled workers is the least prioritized factor. The findings will be useful for successful RL implementation in Indian electronics industry.

    PubMed Central

    2014-01-01

    implementation of a health system to the statewide HIE were found. The most significant perceived success was accomplishing the implementation, although many interviewees also underscored the value of a project champion with decision-making power. In terms of lessons learned, social reasons were found to be very significant motivators for early implementation, frequently outweighing economic motivations. It was clear that understanding the guides early in the project would have mitigated some of the challenges that emerged, and early communication with the electronic health record vendor so that they have a solid understanding of the undertaking was critical. An HIE implementations evaluation framework was found to be useful for assessing challenges, motivations, value propositions for participating, and success factors to consider for future implementations. Conclusions This case study illuminates five critical success factors for implementation of a health system onto a statewide HIE. This study also reveals that organizations have varied motivations and value proposition perceptions for engaging in the exchange of health information, few of which, at the early stages, are economically driven.

  9. Critical factors for a successful astronomical research program in a developing country

    NASA Astrophysics Data System (ADS)

    Hearnshaw, John B.

    I discuss the critical conditions for undertaking a successful research program in a developing country. There are many important factors, all or most of which have to be satisfied: funding, library holdings, computing access, Internet access (e-mail, WWW, ftp, telnet), collaboration with astronomers in developed countries, provision of proper offices for staff, supply of graduate students, access to travel for conferences, ability to publish in international journals, critical mass of researchers, access to a telescope (for observational astronomers), support from and interaction with national electronics, optics and precision engineering industries, a scientific culture backed by a national scientific academy, and lack of inter-institutional rivalry. I make a list of a total of 15 key factors and rank them in order of importance, and discuss the use of an astronomical research index (ARI) suitable for measuring the research potential of a given country or institution. I also discuss whether astronomers in developing countries in principle fare better in a university or in the environment of a government national observatory or research institution, and topics such as the effect of the cost of page charges and journal subscriptions on developing countries. Finally I present some statistics on astronomy in developing countries and relate the numbers of astronomers to the size of the economy and population in each country.

  10. Usability: a critical success factor for managing change in the clinical info-structure.

    PubMed

    Kay, S

    2005-06-01

    There can be no doubt that the clinical info-structure is being significantly enriched with the deployment of new systems throughout the health sector. From a technological perspective, the initial emphasis has been mainly on functionality and only latterly on the usability of these clinical information systems. However, the large scale and rapid pace of the changes being wrought in the health sector will have a major impact on clinicians and patients, not least in how they interact with the technology. Therefore, it is not only hardware and software but people-ware, too, that needs to be actively managed; not simply a one-off functional specification but an ongoing, complex relationship. Usability is the human factor that encompasses the ethical, educational, and evaluative aspects of design. There is also a strong case for regarding usability of clinical information systems as a key critical success factor for the management of change within the health-care domain. In particular, the relationship between usability, and education and training is examined. PMID:16338806

    Manufacturing industries are facing challenges in the implementation of agile manufacturing in their products and processes. Agility is widely accepted as a new competitive concept in the manufacturing sector in fulfilling varying customer demand. Thus, evaluation of agile manufacturing in industries has become a necessity. The success of an organisation depends on its ability to manage finding the critical success factors and give them special and continued attention in order to bring about high performance. This paper proposes a set of critical success factors (CSFs) for evaluating agile manufacturing considered appropriate for the manufacturing sector. The analytical hierarchy process (AHP) method is applied for prioritizing the success factors, by summarizing the opinions of experts. It is believed that the proposed CSFs enable and assist manufacturing industries to achieve a higher performance in agile manufacturing so as to increase competitiveness.

    PubMed

    Bosa, Iris M

    2010-05-01

    New public management accountability is increasingly being introduced into health-care systems throughout the world - albeit with mixed success. This paper examines the successful introduction of new management accounting systems among general practitioners (GPs) as an aspect of reform in the Italian health-care system. In particular, the study examines the critical role played by the novel concept of an 'ethical budget' in engaging the willing cooperation of the medical profession in implementing change. Utilizing a qualitative research design, with in-depth interviews with GPs, hospital doctors and managers, along with archival analysis, the present study finds that management accounting can be successfully implemented among medical professionals provided there is alignment between the management imperative and the ethical framework in which doctors practise their profession. The concept of an 'ethical budget' has been shown to be an innovative and effective tool in achieving this alignment.

    2015-01-01

    Pharmacy barcode scanning is used to reduce errors during the medication dispensing process. However, this technology has rarely been used in hospital pharmacies in Saudi Arabia. This article describes the barriers to successful implementation of a barcode scanning system in Saudi Arabia. A literature review was conducted to identify the relevant critical success factors (CSFs) for a successful dispensing barcode system implementation. Twenty-eight pharmacists from a local hospital in Saudi Arabia were interviewed to obtain their perception of these CSFs. In this study, planning (process flow issues and training requirements), resistance (fear of change, communication issues, and negative perceptions about technology), and technology (software, hardware, and vendor support) were identified as the main barriers. The analytic hierarchy process (AHP), one of the most widely used tools for decision making in the presence of multiple criteria, was used to compare and rank these identified CSFs. The results of this study suggest that resistance barriers have a greater impact than planning and technology barriers. In particular, fear of change is the most critical factor, and training is the least critical factor. PMID:26807079

    2014-01-01

    The so far implemented enterprise resource planning (ERP) systems have in many cases failed to meet the requirements regarding the business process control, decrease of business costs and increase of company profit margin. Therefore, there is a real need for an evaluation of the influence of ERP on the company's performance indicators. Proposed in this article is an advanced model for the evaluation of the success of ERP implementation on organisational and operational performance indicators in oil-gas companies. The recommended method establishes a correlation between a process-based method, a scorecard model and ERP critical success factors. The method was verified and tested on two case studies in oil-gas companies using the following procedure: the model was developed, tested and implemented in a pilot gas-oil company, while the results were implemented and verified in another gas-oil company.

    Den norske statsoljeselskap a.s. (Statoil) which is a major Norwegian oil company has used a mainframe (VM/CMS) based occupational health information system (OHIS) since 1991. The system is distributed among 11 offshore platforms, two refineries and three office centers. It contains medical (25000) workplace (1500) and 6500 material safety data sheet (MSDS) records. The paper deals with the experiences and challenges met during the development of this system and a new client/server based version for Windows{reg_sign}. In 1992 the Norwegian Data Inspectorate introduced new legislation setting extremely strict standards for data protection and privacy. This demanded new solutions not yet utilized for systems of this scale. The solution implements a fully encrypted data flow between the user of the medical modules, while the non sensitive data from the other modules are not encrypted. This involves the use of a special {open_quotes}smart-card{close_quotes} containing the user privileges as well as the encryption key. The system will combine the advantages of a local system together with the integration force of a centralized system. The new system was operational by February 1996. The paper also summarizes the experiences we have had with our OHIS, areas of good and bad cost/benefit, development pitfalls, and which factors are most important for customer satisfaction. This is very important because of the ever increasing demand for efficiency together with company reorganization and changing technology.

    Tourism industry has become the highlighted sector which has amazingly increased the national income level. Despite the tourism industry being one of the highest income generating sectors, Homestay Programme as a Community-Based Tourism (CBT) product in Malaysia does not absorbed much of the incoming wealth. Homestay Programme refers to a programme in a community where a tourist stays together with a host family and experiences the everyday way of life of the family in both direct and indirect manner. There are over 100 Homestay Programme currently being registered with the Ministry of Culture and Tourism Malaysia which mostly are located in rural areas, but only a few excel and enjoying the fruit of the booming industry. Hence, this article seeks to identify the critical success factors for a Community-Based Rural Homestay Programme in Malaysia. A modified pairwise method is utilized to further evaluate the identified success factors in a more meaningful way. The findings will help Homestay Programme function as a community development tool that manages tourism resources. Thus, help the community in improving local economy and creating job opportunities.

    Species previously unknown to science are continually discovered and some of these species already face extinction at the time of their discovery. Conserving new and rare species in these cases becomes a trial-and-error process and conservationists will attempt to manage them by using knowledge of closely related species, or those that fill the same ecological niche, and then adapting the management program as needed. Savannas Mint (Dicerandra immaculata Lakela var. savannarum Huck) is a perennial plant that was discovered in Florida scrub habitat at two locations in 1995, but is nearly extinct at these locations. We tested whether shade, leaf litter, propagation method, parent genotype, parent collection site, planting date, and absorbent granules influenced survival, reproduction, and recruitment of Savannas Mint in a population of 1,614 plants that we introduced between June 2006 and July 2009 into a state protected site. Survival and reproduction of introduced plants, and recruitment of new plants, was higher in microhabitats in full sun and no leaf litter and lower in partially shaded habitats. The two sites from which parent plants were collected differentially influenced survival and reproduction of introduced plants. These differences in survival and reproduction are likely due to underlying genetic differences. Differential survival of progeny from different parent genotypes further supports the idea that underlying genetics is an important consideration when restoring plant populations. The most successful progeny of parent genotypes had survival rates nearly 12 times higher than the least successful progeny. We speculate that many of these environmental and genetic factors are likely to influence allopatric congeners and other critically endangered gap specialists that grow in Florida scrub and our results can be used to guide their conservation.

    Enyinda, Chris I.

    2002-01-01

    In response to the unrelenting call in both public and private sectors fora to reduce the high cost associated with space transportation, many innovative partially or fully RLV (Reusable Launch Vehicles) designs (X-34-37) were initiated. This call is directed at all levels of space missions including scientific, military, and commercial and all aspects of the missions such as nonrecurring development, manufacture, launch, and operations. According to Wertz, tbr over thirty years, the cost of space access has remained exceedingly high. The consensus in the popular press is that to decrease the current astronomical cost of access to space, more safer, reliable, and economically viable second generation RLVs (SGRLV) must be developed. Countries such as Brazil, India, Japan, and Israel are now gearing up to enter the global launch market with their own commercial space launch vehicles. NASA and the US space launch industry cannot afford to lag behind. Developing SGRLVs will immeasurably improve the US's space transportation capabilities by helping the US to regain the global commercial space markets while supporting the transportation capabilities of NASA's space missions, Developing the SGRLVs will provide affordable commercial space transportation that will assure the competitiveness of the US commercial space transportation industry in the 21st century. Commercial space launch systems are having difficulty obtaining financing because of the high cost and risk involved. Access to key financial markets is necessary for commercial space ventures. However, public sector programs in the form of tax incentives and credits, as well as loan guarantees are not yet available. The purpose of this paper is to stimulate discussion and assess the critical success factors germane for RLVs development and US global competitiveness.

    2015-01-01

    Background We evaluated 3 commercially available enzymes for pancreatic digestion by comparing key parameters during the islet isolation process, as well as islet quality after isolation. Methods Retrospectively compared and analyzed islet isolations from pancreata using 3 different enzyme groups: liberase HI (n = 63), collagenase NB1/neutral protease (NP) (n = 43), and liberase mammalian tissue-free collagenase/thermolysin (MTF C/T) (n = 115). A standardized islet isolation and purification method was used. Islet quality assessment was carried out using islet count, viability, in vitro glucose-stimulated insulin secretion (GSIS), glucose-stimulated oxygen consumption rate, and in vivo transplantation model in mice. Results Donor characteristics were not significantly different among the 3 enzyme groups used in terms of age, sex, hospital stay duration, cause of death, body mass index, hemoglobin A1c, cold ischemia time, and pancreas weight. Digestion efficacy (percentage of digested tissue by weight) was significantly higher in the liberase MTF C/T group (73.5 ± 1.5 %) when compared to the liberase HI group (63.6 ± 2.3 %) (P < 0.001) and the collagenase NB1/NP group (61.7 ± 2.9%) (P < 0.001). The stimulation index for GSIS was significantly higher in the liberase MTF C/T group (5.3 ± 0.5) as compared to the liberase HI (2.9 ± 0.2) (P < 0.0001) and the collagenase NB1/NP (3.6 ± 2.9) (P = 0.012) groups. Furthermore, the liberase MTF C/T enzymes showed the highest success rate of transplantation in diabetic non-obese diabetic severe combined immunodeficiency mice (65%), which was significantly higher than the liberase HI (42%, P = 0.001) and the collagenase NB1/NP enzymes (41%, P < 0.001). Conclusions Liberase MTF C/T is superior to liberase HI and collagenase NB1/NP in terms of digestion efficacy and GSIS in vitro. Moreover, liberase MTF C/T had a significantly higher success rate of transplantation in diabetic NOD Scid mice compared to liberase HI and

    1983-04-01

    The authors present data on all insanity pleas (N = 202) in Erie County, New York, between 1970 and 1980. No demographic, criminal history, current offense, or history of mental hospitalization factor was associated with acquittal. Of the variables studied, only the recommendation of the forensic examiner was associated with the court's decision to acquit by reason of insanity. When an insanity acquittal was recommended in the examination report, conviction ensued in only 17% of the cases. The proportion of pleas that were successful varied considerably over the 10 years studied. The authors discuss the critical need for more research on the plea stage of insanity defense proceedings.

  12. Review of critical factors for SEA implementation

    SciTech Connect

    Zhang Jie Christensen, Per; Kornov, Lone

    2013-01-15

    The implementation process involved in translating Strategic Environmental Assessment (SEA) intention into action is vital to an effective SEA. Many factors influence implementation and thus the effectiveness of an SEA. Empirical studies have identified and documented some factors influencing the implementation of an SEA. This research is fragmented, however, and it is still not clear what are the most critical factors of effective SEA performance, and how these relate to different stages of the implementation process or other contextual circumstances. The paper takes its point of departure in implementation theory. Firstly, we introduce implementation theory, and then use it in practice to establish a more comprehensive model related to the stages in the implementation process. Secondly, we identify the critical factors in order to see how they are related to the different stages of SEA or are more general in character. Finally we map the different critical factors and how they influence the overall results of an SEA. Based on a literature review, we present a comprehensive picture of the critical factors and where they are found in the process. We conclude that most of the critical factors identified are of a more general character influencing the SEA process as such, while only one out of four of these factors relates to the specific stages of the SEA. Based on this mapping we can sketch a picture of the totality of critical factors. In this study 266 notions of critical factors were identified. Seen at the level of notions of critical factors, only 24% of these relate to specific stages while for 76% the critical factors are of a more general nature. These critical factors interact in complex ways and appear in different combinations in different stages of the implementation process so tracing the cause and effect is difficult. The pervasiveness of contextual and general factors also clearly suggests that there is no single way to put SEA into practice. The

    Singh, Devin; Matava, Clyde

    2016-01-01

    Background Audio and video podcasts have gained popularity in recent years. Increasingly, podcasts are being used in the field of medicine as a tool to disseminate information. This format has multiple advantages including highly accessible creation tools, low distribution costs, and portability for the user. However, despite its ongoing use in medical education, there are no data describing factors associated with the success or quality of podcasts. Objective The goal of the study was to assess the landscape of anesthesia podcasts in Canada and develop a methodology for evaluating the quality of the podcast. To achieve our objective, we identified the scope of podcasts in anesthesia specifically, constructed an algorithmic model for measuring success, and identified factors linked to both successful podcasts and a peer-review process. Methods Independent reviewers performed a systematic search of anesthesia-related podcasts on iTunes Canada. Data and metrics recorded for each podcast included podcast’s authorship, number posted, podcast series duration, target audience, topics, and social media presence. Descriptive statistics summarized mined data, and univariate analysis was used to identify factors associated with podcast success and a peer-review process. Results Twenty-two podcasts related to anesthesia were included in the final analysis. Less than a third (6/22=27%) were still active. The median longevity of the podcasts’ series was just 13 months (interquartile range: 1-39 months). Anesthesiologists were the target audience for 77% of podcast series with clinical topics being most commonly addressed. We defined a novel algorithm for measuring success: Podcast Success Index. Factors associated with a high Podcast Success Index included podcasts targeting fellows (Spearman R=0.434; P=.04), inclusion of professional topics (Spearman R=0.456-0.603; P=.01-.03), and the use of Twitter as a means of social media (Spearman R=0.453;P=.03).

  15. Factors Related to Successful Engineering Team Design

    NASA Technical Reports Server (NTRS)

    Nowaczyk, Ronald H.; Zang, Thomas A.

    1998-01-01

    The perceptions of a sample of 49 engineers and scientists from NASA Langley Research Center toward engineering design teams were evaluated. The respondents rated 60 team behaviors in terms of their relative importance for team success. They also completed a profile of their own perceptions of their strengths and weaknesses as team members. Behaviors related to team success are discussed in terms of those involving the organizational culture and commitment to the team and those dealing with internal team dynamics. The latter behaviors included the level and extent of debate and discussion regarding methods for completing the team task and the efficient use of team time to explore and discuss methodologies critical to the problem. Successful engineering teams may find their greatest challenges occurring during the early stages of their existence. In contrast to the prototypical business team, members on an engineering design share expertise and knowledge which allows them to deal with task issues sooner. However, discipline differences among team members can lead to conflicts regarding the best method or approach to solving the engineering problem.

    Downey, Laura M; Ireson, Carol L; Slavova, Svetla; McKee, Genia

    2008-04-01

    In recent decades, coalitions have been established to address many public health problems, including injury prevention. A partnership among the Kentucky Injury Prevention and Research Center and four injury prevention coalitions has documented the developmental stages of successful coalitions. This developmental process was constructed through the analysis of participating coalition documents, such as each coalition's mission statement, bylaws or rules of operation, the use of committees within the organization, frequency of meetings, and additional historical documents. Themes from this analysis guided researchers in designing a critical pathway model that describes milestones in coalition formation. Critical components in coalition formation include a clear definition of the coalition structure, coalition enhancement, funding, community support, leadership, education and outreach to the community, membership, partnerships, data and evaluation, and publicity. These findings are applicable to public health professionals who work with community-based coalitions and citizens who participate in local coalitions.

  18. Cancer care critical pathways: implementing a successful program.

    PubMed

    Patton, M D; Katterhagen, J G

    1995-08-01

    Change in any form creates stress on systems, yet there is growing awareness within the health care field that change must come as cost-conscious insurers and employers refuse to pay for overextended processes that grew out of the charge-based reimbursement era. Short-term solutions, such as discounted charges and staff cuts, are not the answer when the entire system needs an overhaul. The cost of care escalates and the quality of patient care suffers because the system lacks the appropriate mechanisms to reduce redundancy, eliminate waste, improve effectiveness, and provide the high-quality care that a community expects from its hospital. The outcomes-based critical pathway approach discussed here has been used with great success and differs from classic pathway writing in that only elements related to the specific outcome are allowed on the order set. The critical pathway process starts with a review of historical patient records, which yields information about both historical practice patterns and the provider team. Using this information, a work group is formed and patient goals or outcomes are established for the population in question. The entire system is informed and educated, with special attention given to the medical staff, clinical outcome and financial data are developed and provided to individuals in the process, and a feedback loop is established. Cancer care is an attractive target for critical pathways, because it is an area with high cost and expensive technology, and physician practice patterns and patient outcomes can vary widely. On the flip side, the historically multidisciplinary nature of cancer care offers a good starting point for the collaborative culture needed to successfully implement critical pathways. When done right, critical pathways can decrease morbidity and mortality, reduce redundancy and cost, increase patient satisfaction, and improve patient outcomes. Shifting practice and eliminating variation in practice patterns, without

Wealth inequality is decreasing over time, and many households work their way out of poverty and lower wealth over the seven year period. The accounts establish that, mechanically, this is largely due to savings rather than incoming gifts and remittances. In turn, the growth of net worth can be decomposed household by household into the savings rate and how productively that savings is used, the return on assets (ROA). The latter plays the larger role. ROA is, in turn, positively correlated with higher education of household members, younger age of the head, and with a higher debt/asset ratio and lower initial wealth, so it seems from cross-sections that the financial system is imperfectly channeling resources to productive and poor households. Household fixed effects account for the larger part of ROA, and this success is largely persistent, undercutting the story that successful entrepreneurs are those that simply get lucky. Persistence does vary across households, and in at least one province with much change and increasing opportunities, ROA changes as households move over time to higher-return occupations. But for those households with high and persistent ROA, the savings rate is higher, consistent with some micro founded macro models with imperfect credit markets. Indeed, high ROA households save by investing in their own enterprises and adopt consistent financial strategies for smoothing fluctuations. More generally growth of wealth, savings levels and/or rates are correlated with TFP and the household fixed effects that are the larger part of ROA. PMID:21643466

    Leucine-rich repeat-containing G-protein-coupled receptor 5 (Lgr5) is expressed in many organs, including female reproductive organs, and is a stem cell marker in the stomach and intestinal epithelium, hair follicles, and ovarian surface epithelium. Despite ongoing studies, the definitive physiological functions of Lgr5 remain unclear. We utilized mice with conditional deletion of Lgr5 (Lgr5d/d) in the female reproductive organs by progesterone receptor-Cre (PgrCre) to determine Lgr5's functions during pregnancy. Only 30% of plugged Lgr5d/d females delivered live pups, and their litter sizes were lower. We found that pregnancy failure in Lgr5d/d females was due to insufficient ovarian progesterone (P4) secretion that compromised decidualization, terminating pregnancy. The drop in P4 levels was reflected in elevated levels of P4-metabolizing enzyme 20α-hydroxysteroid dehydrogenase in corpora lutea (CL) inactivated of Lgr5. Of interest, P4 supplementation rescued decidualization failure and supported pregnancy to full term in Lgr5d/d females. These results provide strong evidence that Lgr5 is critical to normal CL function, unveiling a new role of LGR5 in the ovary.—Sun, X., Terakawa, J., Clevers, H., Barker, N., Daikoku, T., Dey, S. K. Ovarian LGR5 is critical for successful pregnancy. PMID:24469993

  6. Social and cultural factors in the successful control of tuberculosis.

    1992-01-01

    The burden of tuberculosis on the public health is staggering. Worldwide, annual incidence of new cases is estimated to be about 8 million. Almost 3 million deaths occur yearly. Early case identification and adherence to treatment regimens are the remaining barriers to successful control. In many nations, however, fewer than half those with active disease receive a diagnosis, and fewer than half those beginning treatment complete it. The twin problems of delay in seeking treatment and abandonment of a prescribed regimen derive from complex factors. People's confusion as to the implications of the tuberculosis symptoms, costs of transportation to clinic services, the social stigma that attaches to tuberculosis, the high cost of medication, organizational problems in providing adequate followup services, and patients' perception of clinic facilities as inhospitable all contribute to the complexity. Sociocultural factors are emphasized in this report because hitherto they have not been adequately explored. Salient among those sociocultural factors is the health culture of the patients. That is, the understanding and information people have from family, friends, and neighbors as to the nature of a health problem, its cause, and its implications. A knowledge of the health culture of their patients has become a critical tool if tuberculosis control programs are to be successful. Several anthropological procedures are recommended to help uncover the health culture of people served by tuberculosis clinics. PMID:1454974

  7. Critical Questions for Space Human Factors

    Traditional human factors contributions to NASA's crewed space programs have been rooted in the classic approaches to quantifying human physical and cognitive capabilities and limitations in the environment of interest, and producing recommendations and standards for the selection or design of mission equipment. Crews then evaluate the interfaces, displays, or equipment, and with the assistance of human factors experts, improvements are made as funds, time, control documentation, and weight allow. We have come a long way from the early spaceflight days, where men with the ' right stuff were the solution to operating whatever equipment was given to them. The large and diverse Shuttle astronaut corps has impacted mission designs to accommodate a wide range of human capabilities and preferences. Yet with existing long duration experience, we have seen the need to address a different set of dynamics when designing for optimal crew performance: critical equipment and mission situations degrade, and human function changes with mission environment, situation, and duration. Strategies for quantifying the critical nature of human factors requirements are being worked by NASA. Any exploration-class mission will place new responsibilities on mission designers to provide the crew with the information and resources to accomplish the mission. The current duties of a Mission Control Center to monitor system status, detect degradation or malfunction, and provide a proven solution, will need to be incorporated into on-board systems to allow the crew autonomous decision-making. The current option to resupply and replace mission systems and resources, including both vehicle equipment and human operators, will be removed, so considerations of maintenance, onboard training, and proficiency assessment are critical to providing a self-sufficient crew. As we 'move in' to the International Space Station, there are tremendous opportunities to investigate our ability to design for autonomous

  11. Personality Factors and Nuclear Power Plant Operators: Initial License Success

    NASA Astrophysics Data System (ADS)

    DeVita-Cochrane, Cynthia

    Commercial nuclear power utilities are under pressure to effectively recruit and retain licensed reactor operators in light of poor candidate training completion rates and recent candidate failures on the Nuclear Regulatory Commission (NRC) license exam. One candidate failure can cost a utility over $400,000, making the successful licensing of new operators a critical path to operational excellence. This study was designed to discover if the NEO-PI-3, a 5-factor measure of personality, could improve selection in nuclear utilities by identifying personality factors that predict license candidate success. Two large U.S. commercial nuclear power corporations provided potential participant contact information and candidate results on the 2014 NRC exam from their nuclear power units nation-wide. License candidates who participated (n = 75) completed the NEO-PI-3 personality test and results were compared to 3 outcomes on the NRC exam: written exam, simulated operating exam, and overall exam result. Significant correlations were found between several personality factors and both written and operating exam outcomes on the NRC exam. Further, a regression analysis indicated that personality factors, particularly Conscientiousness, predicted simulated operating exam scores. The results of this study may be used to support the use of the NEO-PI-3 to improve operator selection as an addition to the current selection protocol. Positive social change implications from this study include support for the use of a personality measure by utilities to improve their return-on-investment in candidates and by individual candidates to avoid career failures. The results of this study may also positively impact the public by supporting the safe and reliable operation of commercial nuclear power utilities in the United States.

    2015-01-01

    Background Mental health advocacy groups are an effective way of pushing the mental health agenda and putting pressure on national governments to observe the right to health; however, there is limited research that highlights best practices for such groups in low-resource settings. In an effort to improve the scaling up of mental health in Sierra Leone, stakeholders came together to form the country's first mental health advocacy group: the Mental Health Coalition – Sierra Leone. Since its inception, the group has worked towards raising the profile of mental health in Sierra Leone and developing as an advocacy organisation. Design The study's aim was to investigate views on enabling factors and barriers associated with mental health advocacy in a low-income country using a community-based participatory approach and qualitative methodology. Focus groups (N=9) were held with mental health stakeholders, and key informant interviews (N=15) were conducted with advocacy targets. Investigators analysed the data collaboratively using coding techniques informed by grounded theory. Results Investigators reveal viewpoints on key factors in networking, interacting with government actors, and awareness raising that enabled mental health advocacy aims of supporting policy, service delivery, service user rights, training for service delivery, and awareness raising. The investigators outline viewpoints on barriers for advocacy aims in framing the issue of mental health, networking, interacting with government actors, resource mobilization, and awareness raising. Conclusions The findings outline enabling factors, such as networking with key stakeholders, and barriers, such as lack of political will, for achieving mental health advocacy aims within a low-resource setting, Sierra Leone. Stakeholder coalitions can further key policy development aims that are essential to strengthen mental health systems in low-resource settings. PMID:26689456

    Kang, Kyoung Doo; Hannon, James C.; Hall, Morgan S.; Choi, Jae Won

    2015-01-01

    Objective In this five-year cohort study, we hypothesize that factors of temperament and character in professional baseball players predict the speed of obtaining success and the quality of success as well as anxiety control. Methods Participants included 120 male rookie players from the Korea Baseball Organization (KBO) and 107 male non-players with no history of playing baseball. The personality/characters and state/trait anxieties of participants were assessed with the Temperament and Character Inventory (TCI) and Spielberg's State-Trait Anxiety Inventory-Y (STAI-Y). Over the duration of five years, all the players were subsequently classified into either a success group (major leaguers) or a non-success group (non-major leaguers), depending on their status in the professional baseball league in Korea. Results The players in the group of starters had higher novelty seeking (NS) scores than those of non-starters. The reward dependence (RD) scores of the success group were higher than those of the non-success group. The state anxiety scores in the starter group were negatively correlated with NS scores. The state and trait anxieties in the non-success group were positively correlated with RD scores. Conclusion The results of this study suggest that predictive temperamental factors for success in baseball players include traits of novelty seeking and reward dependence. PMID:26508956

    2016-01-01

    Background: Today, the use of information systems in health environments, like any other fields, is necessary and organizational managers are convinced to use these systems. However, managers’ satisfaction is not the only factor in successfully implementing these systems and failed information technology projects (IT) are reported despite the consent of the directors. Therefore, this study aims to determine the factors affecting the successful implementation of a hospital information system. Methods: The study was carried out as a descriptive method in 20 clinical hospitals that the hospital information system (HIS) was conducted in them. The clinical and paraclinical users of mentioned hospitals are the study group. 400 people were chosen as samples in scientific method and the data was collected using a questionnaire consisted of three main human, managerial and organizational, and technological factors, by questionnaire and interview. Then the data was scored in Likert scale (score of 1 to 5) and were analyzed using the SPSS software. Results: About 75 percent of the population were female, with average work experience of 10 years and the mean age was 30 years. The human factors affecting the success of hospital information system implementation achieved the mean score of 3.5, both organizational and managerial factors 2.9 and technological factors the mean of 3. Conclusion: Human factors including computer skills, perceiving usefulness and perceiving the ease of a hospital information system use are more effective on the acceptance and successful implementation of hospital information systems; then the technological factors play a greater role. It is recommended that for the successful implementation of hospital information systems, most of these factors to be considered PMID:27041811

  19. Factors affecting the reproductive success of dominant male meerkats.

    Spong, Göran F; Hodge, Sarah J; Young, Andrew J; Clutton-Brock, Tim H

    2008-05-01

    Identifying traits that affect the reproductive success of individuals is fundamental for our understanding of evolutionary processes. In cooperative breeders, a dominant male typically restricts mating access to the dominant female for extended periods, resulting in pronounced variation in reproductive success among males. This may result in strong selection for traits that increase the likelihood of dominance acquisition, dominance retention and reproductive rates while dominant. However, despite considerable research on reproductive skew, few studies have explored the factors that influence these three processes among males in cooperative species. Here we use genetic, behavioural and demographic data to investigate the factors affecting reproductive success in dominant male meerkats (Suricata suricatta). Our data show that dominant males sire the majority of all offspring surviving to 1 year. A male's likelihood of becoming dominant is strongly influenced by age, but not by weight. Tenure length and reproductive rate, both important components of dominant male reproductive success, are largely affected by group size and composition, rather than individual traits. Dominant males in large groups have longer tenures, but after this effect is controlled, male tenure length also correlates negatively to the number of adult females in the group. Male reproductive rate also declines as the number of intra- and extra-group competitors increases. As the time spent in the dominant position and reproductive rate while dominant explain > 80% of the total variance in reproductive success, group composition thus has major implications for male reproductive success.

Here we use genetic, behavioural and demographic data to investigate the factors affecting reproductive success in dominant male meerkats (Suricata suricatta). Our data show that dominant males sire the majority of all offspring surviving to 1 year. A male's likelihood of becoming dominant is strongly influenced by age, but not by weight. Tenure length and reproductive rate, both important components of dominant male reproductive success, are largely affected by group size and composition, rather than individual traits. Dominant males in large groups have longer tenures, but after this effect is controlled, male tenure length also correlates negatively to the number of adult females in the group. Male reproductive rate also declines as the number of intra- and extra-group competitors increases. As the time spent in the dominant position and reproductive rate while dominant explain > 80% of the total variance in reproductive success, group composition thus has major implications for male reproductive success.

    2012-01-01

    Many English-as-a-Second Language (ESL) nursing students struggle in nursing school for a multitude of reasons. The purpose of this critical review of the literature is to identify barriers and discover bridges to ESL nursing student success. Twenty-five articles were identified for the review. Language barriers were identified as the single most significant obstacle facing the ESL nursing student. Bridges to ESL nursing student success include enhancing language development and acculturation into the American mainstream culture. A broad range of strategies to promote student success are outlined and the role of the nurse educator in ESL nursing student success is also addressed.

    We studied the success and success factors of online support groups (OSGs) for patients, and the motives and goals of people who start such groups. We interviewed 23 webmasters of OSGs for patients with breast cancer, fibromyalgia and arthritis. The majority were women (n = 20) and most were patients (n = 21). Analysis of the interviews revealed that webmasters had altruistic and intrinsic motives for initiating an online support group. They defined success as the fulfilment of the goals they had in mind when they initiated their groups. To be able to make a group successful, decisions about its organization and management need to be coherent with these goals. Most webmasters stressed that promoting the group, keeping it alive and moderating the messages were vital success factors during the evolution stage. Management of the OSGs took up much of the webmasters' time and energy. On average webmasters were occupied with the group for 10-15 hours a week. Our study provides an overview of the pros and cons of differing decisions that have to be made when initiating an OSG. PMID:20086265

    This follow-up study examines the employment success of young adults with learning and other mild disabilities. The study questioned the employee with disabilities, his or her parents, and the employer on a number of vocationally related items. A four-factor model is advanced to explain job success. The factors include job match and accommodation, social acceptance, work attitude, and special services. Participants in a total of 41 job situations were queried with 38 completed triads (employee with mild disability, employer, family). The method of constant comparative analysis was used to analyze the data. Although an aggregate of the four factors correlated significantly (p less than .01), job match proved to have the most significant (p less than .01) relationship with the outcome variable. The results are interpreted in light of the need to deliver and understand the types of supported employment services for adults with mild disabilities.

    2014-01-01

    Successful or healthful aging are terms that draw attention to life course issues related to individual, physical, and psychologic development and maturation, but they also draw attention to the material basis of successful aging and the social structures that determine one’s place in the social hierarchy. This article focuses on barriers to optimal aging for Hispanics, especially those of Mexican origin, and argues that cultural factors and social class are closely associated. The reduction of health disparities and equity in medical and long-term care requires an understanding of both cultural and material sources of differential health levels. PMID:19065093

    Research tells us that academic preparation is key to deaf students' success at college. Yet, that is not the whole story. Many academically prepared students drop out during their first year. This study identified entering deaf college students' personal factors as assessed by their individual responses to both the Noel-Levitz College Student Inventory Form B and the Learning and Study Strategies Inventory, second edition (LASSI). Entering students in 3 successive cohorts (total n =437) participated in this study. Results show that in addition to entry measurements of reading and mathematic skills, personal factors contributed to the academic performance of students in their first quarter in college. The Noel-Levitz provided the comparatively better predictive value of academic performance: Motivation for Academic Study Scale (e.g., desire to finish college). The LASSI also showed statistically significant predictors, the Self-Regulation Component (e.g., time management) and Will Component (e.g., self-discipline), but accounted for relatively less variability in the students' initial grade point averages. For this group of underprepared students, results show that personal factors can play a significant role in academic success. Deaf students' personal factors are discussed as they relate to other first-year college students and to their subsequent academic performance and persistence.

  15. Review of critical factors affecting crude corrosivity

    Tebbal, S.; Kane, R.D.

    1996-08-01

    Lower quality opportunity crudes are now processed in most refineries and the source of the crudes may vary daily. These feedstocks, if not properly handled, can result in reduction in service life of equipment as well as costly failure and downtime. Analytical tools are needed to predict their high temperature corrosivity toward distillation units. Threshold in total sulfur and total acid number (TAN) have been used for many years as rules of thumb for predicting crude corrosivity, However, it is now realized that they are not accurate in their predictive ability. Crudes with similar composition and comparable with respect to process considerations have been found to be entirely different in their impact on corrosion. Naphthenic acid content, sulfur content, velocity, temperature, and materials of construction are the main factors affecting the corrosion process, Despite progress made in elucidating the role of the different parameters on the crude corrosivity process, the main problem is in calculating their combined effect, especially when the corroding stream is such a complex mixture. The TAN is usually related directly to naphthenic acid content. However, discrepancies between analytical methods and interference of numerous components of the crude itself lead to unreliable reported content of naphthenic acid. The sulfur compounds, with respect to corrosivity, appear to relate more to their decomposition at elevated temperature to form hydrogen sulfide than to their total content in crude. This paper reviews the present situation regarding crude corrosivity in distillation units, with the aim of indicating the extent of available information, and areas where further research is necessary.

    The goal of this study was to gather the opinions of prosthetics experts on the most important factors for the successful use of upper-limb (UL) prostheses, compare them with those of prosthesis users, and ultimately direct research efforts in this field. UL prosthetics experts were asked to compare the importance of the comfort, function, and cosmesis of a prosthetic device for a transhumeral amputee. Categories were subdivided into weight, socket-interface comfort, power, agility, color, and shape. The majority of those who responded viewed comfort as the most important factor for a unilateral amputee and considered socket-interface comfort to be more important than weight. Function was considered to be the most important factor for a bilateral amputee, with agility considered more important than power. Cosmesis was consistently reported as being less important than comfort and function, and shape was considered more important than color.

    Understanding factors that influence reproduction and offspring survival in zoo populations is critical for management of threatened and endangered species. Examination of long-term data (1989-2011) compiled from the Association of Zoos and Aquarium's zoo-managed tiger breeding program provides the basis for a more thorough understanding of reproduction and scientifically based decisions for effective population management in this endangered felid. Biological and management-related factors that could influence tiger breeding success and cub survival were evaluated using logistic mixed models. Breeding success improved with female age until approximately age five, then declined thereafter. Experienced female breeders had greater breeding success than inexperienced females. Litter size was most predictive of cub survival, with average-sized litters (3-4 cubs) experiencing the highest proportional survival. Management-related factors, such as whether the breeding institution had a recent tiger litter and whether both animals were already located at the same institution, also influenced breeding success and cub survival. These results highlight the importance of institutional husbandry experience and the need to retain knowledge through staff turnovers to achieve optimal reproductive success. Using fecal estrogen data, frequency of ovarian cyclicity and mean cycle length did not differ by female age or parity; thus, lack of cyclicity and/or increased cycle duration are not likely explanations for declining breeding success with age. These results provide valuable reproductive information that should improve scientific management of zoo-based tiger populations. PMID:24326286

  2. Lessons for public health campaigns from analysing commercial food marketing success factors: a case study

    PubMed Central

    2012-01-01

    Background Commercial food marketing has considerably shaped consumer food choice behaviour. Meanwhile, public health campaigns for healthier eating have had limited impact to date. Social marketing suggests that successful commercial food marketing campaigns can provide useful lessons for public sector activities. The aim of the present study was to empirically identify food marketing success factors that, using the social marketing approach, could help improve public health campaigns to promote healthy eating. Methods In this case-study analysis, 27 recent and successful commercial food and beverage marketing cases were purposively sampled from different European countries. The cases involved different consumer target groups, product categories, company sizes and marketing techniques. The analysis focused on cases of relatively healthy food types, and nutrition and health-related aspects in the communication related to the food. Visual as well as written material was gathered, complemented by semi-structured interviews with 12 food market trend experts and 19 representatives of food companies and advertising agencies. Success factors were identified by a group of experts who reached consensus through discussion structured by a card sorting method. Results Six clusters of success factors emerged from the analysis and were labelled as "data and knowledge", "emotions", "endorsement", "media", "community" and "why and how". Each cluster subsumes two or three success factors and is illustrated by examples. In total, 16 factors were identified. It is argued that the factors "nutritional evidence", "trend awareness", "vertical endorsement", "simple naturalness" and "common values" are of particular importance in the communication of health with regard to food. Conclusions The present study identified critical factors for the success of commercial food marketing campaigns related to the issue of nutrition and health, which are possibly transferable to the public health

    2015-01-01

    Successful aging” is one of gerontology’s most successful ideas. Applied as a model, a concept, an approach, an experience, and an outcome, it has inspired researchers to create affiliated terms such as “healthy,” “positive,” “active,” “productive,” and “effective” aging. Although embraced as an optimistic approach to measuring life satisfaction and as a challenge to ageist traditions based on decline, successful aging as defined by John Rowe and Robert Kahn has also invited considerable critical responses. This article takes a critical gerontological perspective to explore such responses to the Rowe–Kahn successful aging paradigm by summarizing its empirical and methodological limitations, theoretical assumptions around ideas of individual choice and lifestyle, and inattention to intersecting issues of social inequality, health disparities, and age relations. The latter point is elaborated with an examination of income, gender, racial, ethnic, and age differences in the United States. Conclusions raise questions of social exclusion and the future of successful aging research. PMID:24747713

    We describe the health insurance model implemented in Mongolia after the Soviet Bloc collapsed in 1990, and note some of its good features. We then discuss the structural weaknesses that became evident over the first ten years of use, and some current proposals for reform. Finally, we consider the factors that appear to have affected success. We argue that the main constraints are much the same as in other countries including Australia--and relate more to confusion and disagreement over broad policy issues than to detailed knowledge of technical aspects or the research evidence.

    The reproductive success of brown trout Salmo trutta in White River, Arkansas, tailwater reaches is highly variable, resulting in the need for supplemental stocking. A better understanding of the physical and biotic factors affecting reproduction and survival would enhance the contribution of wild fish. We compared fecundity, reproductive chronology, physical habitat, water quality, trout density, food availability, diet, predation, and competitive interactions among four tailwater reaches to identify factors influencing brown trout reproductive success. The fecundity and condition factor of prespawning brown trout were significantly lower at Beaver Tailwater, a reach known for reproductive failure, than at other sites, among which no differences were found. Brown trout spawning was observed from 11 October to 23 November 1996, and juvenile emergence began on 28 February 1997. Significant among-site differences were detected for spawning and juvenile microhabitat variables, but the variables fell within or near suitable or optimal ranges reported in the literature for this species. Age-0 brown trout density differed significantly among sites, but growth and condition did not. Predation by Ozark sculpin Cottus hypselurus on trout eggs or age-0 trout of any species was not observed among the 418 stomachs examined. Ozark sculpin density and diet overlap with age-0 brown trout were highest and invertebrate food availability and water fertility were lowest at Beaver Tailwater relative to the other reaches. Our findings indicate that differences in trophic conditions occur among tailwater reaches, and a lower system productive capacity was identified at Beaver Tailwater. We suggest that management efforts include refining the multispecies trout stocking regime to improve production efficiency, enhancing flow regulation, and increasing habitat complexity to increase invertebrate and fish productivity. Such efforts may lead to improved natural reproduction and the

    Although issues related to the management of invasive alien species are receiving increasing attention, little is known about which factors affect the likelihood of success of management measures. We applied two data mining techniques, classification trees and boosted trees, to identify factors that relate to the success of management campaigns aimed at eradicating invasive alien invertebrates, plants and plant pathogens. We assembled a dataset of 173 different eradication campaigns against 94 species worldwide, about a half of which (50.9%) were successful. Eradications in man-made habitats, greenhouses in particular, were more likely to succeed than those in (semi-)natural habitats. In man-made habitats the probability of success was generally high in Australasia, while in Europe and the Americas it was higher for local infestations that are easier to deal with, and for international campaigns that are likely to profit from cross-border cooperation. In (semi-) natural habitats, eradication campaigns were more likely to succeed for plants introduced as an ornamental and escaped from cultivation prior to invasion. Averaging out all other factors in boosted trees, pathogens, bacteria and viruses were most, and fungi the least likely to be eradicated; for plants and invertebrates the probability was intermediate. Our analysis indicates that initiating the campaign before the extent of infestation reaches the critical threshold, starting to eradicate within the first four years since the problem has been noticed, paying special attention to species introduced by the cultivation pathway, and applying sanitary measures can substantially increase the probability of eradication success. Our investigations also revealed that information on socioeconomic factors, which are often considered to be crucial for eradication success, is rarely available, and thus their relative importance cannot be evaluated. Future campaigns should carefully document socioeconomic factors to

    Bornsen, Susan Edith

    It is no surprise that there is a shortage of women engineers. The reasons for the shortage have been researched and discussed in myriad papers, and suggestions for improvement continue to evolve. However, there are few studies that have specifically identified the positive aspects that attract women to engineering and keep them actively engaged in the field. This paper examines how women engineers view their education, their work, and their motivation to remain in the field. A qualitative research design was used to understand the motivation and adaptability factors women use to support their decision to major in engineering and stay in the engineering profession. Women engineers were interviewed using broad questions about motivation and adaptability. Interviews were transcribed and coded, looking for common threads of factors that suggest not only why women engineers persist in the field, but also how they thrive. Findings focus on the experiences, insights, and meaning of women interviewed. A grounded theory approach was used to describe the success factors found in practicing women engineers. The study found categories of attraction to the field, learning environment, motivation and adaptability. Sub-categories of motivation are intrinsic motivational factors such as the desire to make a difference, as well as extrinsic factors such as having an income that allows the kind of lifestyle that supports the family. Women engineers are comfortable with and enjoy working with male peers and when barriers arise, women learn to adapt in the male dominated field. Adaptability was indicated in areas of gender, culture, and communication. Women found strength in the ability to 'read' their clients, and provide insight to their teams. Sufficient knowledge from the field advances theory and offers strategies to programs for administrators and faculty of schools of engineering as well as engineering firms, who have interest in recruitment, and retention of female students

    Purpose The purpose of this paper is to investigate the elements that health care personnel in Thailand believe are necessary for successful adoption of electronic medical record (EMR) systems. Design/methodology/approach Initial qualitative in-depth interviews with physicians to adapt key elements from the literature to the Thai context. The 12 elements identified included things related to managing the implementation and to IT expertise. The nationwide survey was supported by the Ministry of Public Health and returned 1,069 usable questionnaires (response rate 42 percent) from a range of medical personnel. Findings The key elements clearly separated into a managerial dimension and an IT dimension. All were considered fairly important, but managerial expertise was more critical. In particular, there should be clear EMR project goals and scope, adequate budget allocation, clinical staff must be involved in implementation, and the IT should facilitate good electronic communication. Research limitations/implications Thailand is representative of middle-income developing countries, but there is no guarantee findings can be generalized. National policies differ, as do economic structures of health care industries. The focus is on management at the organizational level, but future research must also examine macro-level issues, as well as gain more depth into thinking of individual health care personnel. Practical implications Technical issues of EMR implementation are certainly important. However, it is clear actual adoption and use of the system also depends very heavily on managerial issues. Originality/value Most research on EMR implementation has been in developed countries, and has often focussed more on technical issues rather than examining managerial issues closely. Health IT is also critical in developing economies, and management of health IT implementation must be well understood. PMID:27681029

Findings The key elements clearly separated into a managerial dimension and an IT dimension. All were considered fairly important, but managerial expertise was more critical. In particular, there should be clear EMR project goals and scope, adequate budget allocation, clinical staff must be involved in implementation, and the IT should facilitate good electronic communication. Research limitations/implications Thailand is representative of middle-income developing countries, but there is no guarantee findings can be generalized. National policies differ, as do economic structures of health care industries. The focus is on management at the organizational level, but future research must also examine macro-level issues, as well as gain more depth into thinking of individual health care personnel. Practical implications Technical issues of EMR implementation are certainly important. However, it is clear actual adoption and use of the system also depends very heavily on managerial issues. Originality/value Most research on EMR implementation has been in developed countries, and has often focussed more on technical issues rather than examining managerial issues closely. Health IT is also critical in developing economies, and management of health IT implementation must be well understood.

    Background: Aging is an irreversible natural process characterized by a decline in both the physical and mental status of individuals. Because of multiple factors, this process and its consequences vary greatly between individuals. A successful aging (SA) is the target of current health policies and well-being of individuals. Knowing the factors that contribute to SA and its barriers would translate in measurements that increase the quality of life of elderly and reduce health costs. Objectives: The aim of this study was to explore barriers and facilitators to Iranian elderly women’s SA. Patients and Methods: A purposive sample of 16 elderly women, aged 61 - 96 years, was recruited for this qualitative content analysis study. Study data were collected during 2012 -.2013 by conducting 16 face-to-face semi-structured in-depth interviews. We continued the data collection until reaching saturation. Study data were analyzed concurrently with data collection, by using the conventional qualitative content analysis approach. Results: Barriers and facilitators to Iranian elderly women’s SA fell into five main categories, including availability of support systems, state of health, personal capabilities, personality characteristics, and lifestyle. Conclusions: Availability of support systems, state of health, personal capabilities, personality characteristics, and lifestyle were the main interrelated factors affecting Iranian elderly women’s SA. Accordingly, providing elderly women with strong educational, emotional, financial, cultural, and social supports can help facilitate their SA. PMID:26421171

  14. Expecting success: Factors influencing ninth graders' science self-efficacy

    Donahue, Elizabeth

    What factors influence ninth grade students' expectations for success in science? Using social cognitive theory and bioecological systems theory as theoretical frameworks, this dissertation employs data from the High School Longitudinal Study of 2009 (HSLS:09) to examine the relative impact of teacher practices and their perceived attitudes on students' science self-efficacy. Further, as they relate to this broader issue, the relative impact of student subjective task value and teacher characteristics is also investigated. It has been well documented that U.S. students are not achieving at satisfactory levels in science. Education policy has focused on improving science teacher quality as one way to address this problem. Teacher effectiveness has been primarily measured by student achievement on standardized tests. However, not enough attention has been given to the social cognitive factors that can lead to increased achievement and persistence in science as well as how teachers may influence these factors. This study interrogates the relationship between student and teacher variables and the social cognitive construct of self-efficacy, which has proven to have a significant impact on student achievement and persistence in science. Findings add to the current literature surrounding ways that educators may increase student performance in science by employing policies and practices that benefit the development of student science self-efficacy.

  15. [Success factors of work-related orthopaedic rehabilitation].

    2011-06-01

    Work-related rehabilitation has for several years been gaining greater importance in orthopaedic rehabilitation. High-quality studies have confirmed that work-related medical rehabilitation has favourable effects on earning capacity and work-life participation. This does however not hold true for all work-related rehabilitation programmes. In this context, 5 theses concerning success factors of work-related medical rehabilitation are developed. It is set out that the effects of work-related medical rehabilitation on work ability and work-life participation can be improved if programmes realize a needs-oriented assignment, include cognitive-behavioural components, follow a multimodal approach, step up treatment intensity, and if treatments are manualized.

    In contrast to immune restrictions that pertain for solid organ transplants, the tolerogenic milieu of the eye permits successful corneal transplantation without systemic immunosuppression, even across a fully MHC disparate barrier. Here we show that recipient and donor expression of decay accelerating factor (DAF or CD55), a cell surface C3/C5 convertase regulator recently shown to modulate T cell responses, is essential to sustain successful corneal engraftment. Whereas wild type (WT) corneas transplanted into multiple minor histocompatibility antigen (mH), or HY disparate WT recipients were accepted, DAF’s absence on either the donor cornea or in the recipient bed induced rapid rejection. Donor or recipient DAF deficiency led to expansion of donor-reactive IFN-γ producing CD4+ and CD8+ T cells, as well as inhibition of antigen induced IL-10 and TGF-β, together demonstrating that DAF deficiency precludes immune tolerance. In addition to demonstrating a requisite role for DAF in conferring ocular immune privilege, these results raise the possibility that augmenting DAF levels on corneal endothelium and/or the recipient bed could have therapeutic value for transplants that clinically are at high risk for rejection.

    Extant literature suggests people-centred factors as one of the major areas influencing enterprise resource planning (ERP) implementation project success. Yet, to date, few empirical studies attempted to validate the link between people-centred factors and ERP implementation project success. The purpose of this study is to empirically identify people-centred factors that are critical to ERP implementation projects in Sri Lanka. The study develops and empirically validates a framework for people-centred factors that influence the success of ERP implementation projects. Survey research methodology was used and collected data from 74 ERP implementation projects in Sri Lanka. The people-centred factors of 'project team competence', 'rewards' and 'communication and change' were found to predict significantly the ERP implementation project success.

    Type 2 diabetes can be a problem for captive chimpanzees. Accurate blood glucose (BG) readings are necessary to monitor and treat this disease. Thus, obtaining voluntary samples from primates through positive reinforcement training (PRT) is critical. The current study assessed the voluntary participation of 123 chimpanzees in BG sampling and investigated factors that may contribute to individual success. All subjects participate in regular PRT sessions as part of a comprehensive behavioral management program. Basic steps involved in obtaining BG values include: voluntarily presenting a finger/toe; allowing digit disinfection; holding for the lancet device; and allowing blood collection onto a glucometer test strip for analysis. We recorded the level of participation (none, partial, or complete) when each chimpanzee was first asked to perform the testing procedure. Nearly 30% of subjects allowed the entire procedure in one session, without any prior specific training for the target behavior. Factors that affected this initial successful BG testing included sex, personality (chimpanzees rated higher on the factor "openness" were more likely to participate with BG testing), and past training performance for "present-for-injection" (chimpanzees that presented for their most recent anesthetic injection were more likely to participate). Neither age, rearing history, time since most recent anesthetic event nor social group size significantly affected initial training success. These results have important implications for captive management and training program success, underlining individual differences in training aptitude and the need for developing individual management plans in order to provide optimal care and treatment for diabetic chimpanzees in captivity.

    We study the massless flows described by the staircase model introduced by Al.B. Zamolodchikov through the analytic continuation of the sinh-Gordon S-matrix, focusing on the renormalisation group flow from the tricritical to the critical Ising model. We show that the properly defined roaming limits of certain sinh-Gordon form factors are identical to the form factors of the order and disorder operators for the massless flow. As a by-product, we also construct form factors for a semi-local field in the sinh-Gordon model, which can be associated with the twist field in the ultraviolet limiting free massless bosonic theory.

    1999-07-01

    Successive Alkalinity Producing Systems (SAPS) are passive treatment wetlands that have been used successfully in renovating acidic mine drainage (AMD) for several years. Unfortunately, design parameters and treatment efficiency of these systems vary widely due to a lack of clear, consistent design and construction guidelines. This study is investigating ten operating SAPS systems in Virginia and West Virginia for the purpose of identifying the relationship of design and construction factors to system performance. Influent and effluent water samples were collected for a period of two years or longer by the operators of each system. Each sample was analyzed for pH, alkalinity, acidity, sulfate, total iron, total manganese, and aluminum. The individual systems were also characterized according to system age, size, and construction materials. Residence times for the ten systems ranged from 4.5 hours to 13.31 days. On average, they were able to raise the pH 0.65 units and generate a net alkalinity of 84.84 mg/l as CaCO{sub 3}. Iron and manganese removal did occur in the SAPS cells, but the majority of the removal took place in post-SAPS settling ponds. Net alkalinity generation was positively correlated with residence time and iron removal rates suggesting a synergistic effect. Seasonal variation in alkalinity production was also noted, possibly indicating changes in alkalinity generation rates by dissimilatory sulfate reduction. These data provide the foundation for the development of a user-oriented SAPS design model based solely on influent AMD chemistry and final treatment goals as input parameters.

    Career opportunities in business and industry have been identified as one area of growth for the dietetics profession. The purposes of this study were to identify the skills, attributes, and knowledge areas dietitians need to succeed in business and industry; ascertain methods used to acquire these; assess factors that influenced career change; and determine the degree of perceived adequacy of academic preparation by practitioners employed in business and industry. A questionnaire, developed on the basis of a Delphi study involving 21 dietitians employed in business and industry, was administered to a national sample of 387 members of the Dietitians in Business and Industry (DIBI) dietetic practice group who were employed in business and industry. The overall response rate was 299 (77%); respondents were from 39 states. Skills, attributes, and knowledge areas were identified for specific employment classifications in business and industry. Self-motivation and work experience in business were identified as the most important methods for acquiring skills for this area of practice. Challenge of a new position and diversity of job responsibilities had the most influence on career change of respondents. Undergraduate and graduate education were rated somewhat inadequate and adequate, respectively, by the majority of respondents. The findings indicate that positions in business and industry require specific skills, attributes, and knowledge that may not necessarily be attained through traditional approaches. Self-assessment and appropriate self-development activities are essential for success.

    Reducing maternal and child mortality is a priority in the Millennium Development Goals (MDGs), and will likely remain so after 2015. Evidence exists on the investments, interventions and enabling policies required. Less is understood about why some countries achieve faster progress than other comparable countries. The Success Factors for Women's and Children's Health studies sought to address this knowledge gap using statistical and econometric analyses of data from 144 low- and middle-income countries (LMICs) over 20 years; Boolean, qualitative comparative analysis; a literature review; and country-specific reviews in 10 fast-track countries for MDGs 4 and 5a. There is no standard formula--fast-track countries deploy tailored strategies and adapt quickly to change. However, fast-track countries share some effective approaches in addressing three main areas to reduce maternal and child mortality. First, these countries engage multiple sectors to address crucial health determinants. Around half the reduction in child mortality in LMICs since 1990 is the result of health sector investments, the other half is attributed to investments made in sectors outside health. Second, these countries use strategies to mobilize partners across society, using timely, robust evidence for decision-making and accountability and a triple planning approach to consider immediate needs, long-term vision and adaptation to change. Third, the countries establish guiding principles that orient progress, align stakeholder action and achieve results over time. This evidence synthesis contributes to global learning on accelerating improvements in women's and children's health towards 2015 and beyond.

    The efficacy of assisted reproductive technologies has improved significantly over the past decades. The main indications for in vitro fertilisation include tubal obstruction, severe male-factor infertility, severe endometriosis, ovulatory dysfunction, diminished ovarian reserve, and infertility of unexplained cause. In vitro fertilisation has also become an effective treatment option for couples wishing to undergo pre-implantation genetic diagnosis or screening, and for those wishing to cryopreserve their oocytes or embryos for preservation of fertility. The management of women in late reproductive age poses a major challenge; the optimum in vitro fertilisation treatment for poor responders remains elusive. The success of in vitro fertilisation treatment can be optimised by taking an individualised, patient-centered approach to controlled ovarian hyperstimulation. Key components involve selection of an appropriate controlled ovarian protocol, close-cycle monitoring, adjustment of gonadotropin dosage to avoid hyper-response, and individualised timing of human chorionic gonadotropin injection. Future directions of assisted reproductive technologies include development of non-invasive embryo selection methods, use of transcriptomics, proteomics, metabolomics, and time-lapse imaging technologies.

    Food procurement can play an important role in sustainable food supply chain management by zoos, linking organizational operations to the biodiversity conservation and sustainability mission of zoological collections. This study therefore examines the critical factors that shape sustainable food procurement in zoo and aquariums. Using a web-based survey data was collected from 41 members of the British and Irish Association of Zoos and Aquariums (BIAZA). This included information on the sustainable food procurement practices of these institutions for both their human and animal food supply chains, as well as profile information and data on the factors contributing to and inhibiting sustainable procurement practices. Zoological collections operated by charities, and those with a certified sustainability standard, were found to have significantly higher levels of sustainable food procurement. Zoos and aquariums whose human food operations were not contracted to an external party were also found to have significantly higher levels of sustainable food procurement in their human food supply chain. The most important drivers of sustainable food procurement were cost savings, adequate financial support and improved product quality. The highest ranking barriers were higher costs, other issues taking priority and a lack of alternative suppliers. The results suggest that a number of critical factors shape sustainable food procurement in zoological collections in the British Isles. Financial factors, such as cost savings, were important considerations. The significance of mission-related factors, such as charity status, indicated that core values held by zoos and aquariums can also influence their food procurement practices.

    While workers' safety risk tolerances have been regarded as a main reason for their unsafe behaviors, little is known about why different people have different risk tolerances even when confronting the same situation. The aim of this research is to identify the critical factors and paths that influence workers' safety risk tolerance and to explore how they contribute to accident causal model from a system thinking perceptive. A number of methods were carried out to analyze the data collected through interviews and questionnaire surveys. In the first and second steps of the research, factor identification, factor ranking and factor analysis were carried out, and the results show that workers' safety risk tolerance can be influenced by four groups of factors, namely: (1) personal subjective perception; (2) work knowledge and experiences; (3) work characteristics; and (4) safety management. In the third step of the research, hypothetical influencing path model was developed and tested by using structural equation modeling (SEM). It is found that the effects of external factors (safety management and work characteristics) on risk tolerance are larger than that of internal factors (personal subjective perception and work knowledge & experiences). Specifically, safety management contributes the most to workers' safety risk tolerance through its direct effect and indirect effect; while personal subjective perception comes the second and can act as an intermedia for work characteristics. This research provides an in-depth insight of workers' unsafe behaviors by depicting the contributing factors as shown in the accident causal model developed in this research. PMID:26775077

  17. Identifying Sociological Factors for the Success of Space Exploration

    NASA Astrophysics Data System (ADS)

    Lundquist, C. A.; Tarter, D.; Coleman, A.

    Astrosociology factors relevant to success of future space exploration may best be identified through studies of sociological circumstances of past successful explorations, such as the Apollo-Lunar Missions. These studies benefit from access to primary records of the past programs. The Archives and Special Collections Division of the Salmon Library at the University of Alabama Huntsville (UAH) houses large collections of material from the early periods of the space age. The Huntsville campus of the University of Alabama System had its birth in the mid-1950s at the time when the von Braun rocket team was relocated from Texas to Huntsville. The University, the City of Huntsville and the US Government rocket organizations developed in parallel over subsequent years. As a result, the University has a significant space heritage and focus. This is true not only for the engineering and science disciplines, but also for the social sciences. The life of the University spans the period when Huntsville government and industrial organizations were responsible for producing the rocket vehicles to first take mankind to the Moon. That endeavor was surely as significant sociologically as technologically. In the 1980s, Donald E. Tarter, conducted a series of video interviews with some leading members of the original von Braun team. Although the interviews ranged over many engineering subjects, they also recorded personal features of people involved in the Apollo lunar exploration program and the interactions between these people. Such knowledge was of course an objective. These interviews are now in the collections of the UAH Library Archives, along with extensive documentation from the same period. Under sponsorship of the Archives and the NASA-Marshall Retiree Association, the interview series was restarted in 2006 to obtain comparable oral-history interviews with more than fifty US born members of the rocket team from the 1960s. Again these video interviews are rich with

    Leaders of critical care programs have significant responsibility to develop and maintain a system of intensive care. At inception, those clinician resources necessary to provide and be available for the expected range of patient illness and injury and throughput are determined. Simultaneously, non-ICU clinical responsibilities and other expectations, such as education of trainees and participation in hospital operations, must be understood. To meet these responsibilities, physicians must be recruited, mentored, and retained. The physician leader may have similar responsibilities for nonphysician practitioners. In concert with other critical care leaders, the service adopts a model of care and assembles an ICU team of physicians, nurses, nonphysician providers, respiratory therapists, and others to provide clinical services. Besides clinician resources, leaders must assure that services such as radiology, pharmacy, the laboratory, and information services are positioned to support the complexities of ICU care. Metrics are developed to report success in meeting process and outcomes goals. Leaders evolve the system of care by reassessing and modifying practice patterns to continually improve safety, efficacy, and efficiency. Major emphasis is placed on the importance of continuity, consistency, and communication by expecting practitioners to adopt similar practices and patterns. Services anticipate and adapt to evolving expectations and resource availability. Effective services will result when skilled practitioners support one another and ascribe to a service philosophy of care. PMID:25746743

    Leaders of critical care services require knowledge and skills not typically acquired during their medical education and training. Leaders possess personality characteristics and evolve and adopt behaviors and knowledge in addition to those useful in the care of patients and rounding with an ICU team. Successful leaders have impeccable integrity, possess a service mentality, are decisive, and speak the truth consistently and accurately. Effective leaders are thoughtful listeners, introspective, develop a range of relationships, and nurture others. They understand group psychology, observe, analyze assumptions, decide, and improve the system of care and the performance of their team members. A leader learns to facilely adapt to circumstance, generate new ideas, and be a catalyst of change. Those most successful further their education as a leader and learn when and where to seek mentorship. Leaders understand their organization and its operational complexities. Leaders learn to participate and knowledgeably contribute to the fiscal aspects of income, expense, budget, and contracts from an institutional and department perspective. Clinician compensation must be commensurate with expectations and be written to motivate and make clear duties that are clinical and nonclinical. A leader understands and plans to address the evolving challenges facing healthcare, especially resource constraints, the emotions and requirements of managing the end of life, the complexities of competing demands and motivations, the bureaucracy of healthcare practice, and reimbursement. Responsibilities to manage and evolve must be met with intelligence, sensitivity, and equanimity.

    OBJECTIVE To identify potential predictors for treatment success in medical management with misoprostol for early pregnancy failure. METHODS We conducted a planned secondary analysis of data from a multicenter trial that compared medical and surgical management of early pregnancy failure. Medical management consisted of misoprostol 800 μg vaginally on study day 1, with a repeat dose if indicated on day 3. Women returned on days 3 and 15, and a telephone interview was conducted on day 30. Failure was defined as suction aspiration for any reason within 30 days. Demographic, historical, and outcome variables were included in univariable analyses of success. Multivariable analyses were conducted using clinical site, gestational age, and variables for which the univariable analysis resulted in a P < .1 to determine predictors of overall treatment success and first-dose success. RESULTS Of the 491 women who received misoprostol, 485 met the criteria for this secondary analysis. Lower abdominal pain or vaginal bleeding within the last 24 hours, Rh-negative blood type, and nulliparity were predictive of overall success. However, only vaginal bleeding within the last 24 hours and parity of 0 or 1 were predictive of first-dose success. Overall success exceeds 92% in women who have localized abdominal pain within the last 24 hours, Rh-negative blood type, or the combination of vaginal bleeding in the past 24 hours and nulliparity. CONCLUSION Misoprostol treatment for early pregnancy failure is highly successful in select women, primarily those with active bleeding and nulliparity. Clinicians and patients should be aware of these differences when considering misoprostol treatment. PMID:16582130

    Type 2 diabetes can be a problem for captive chimpanzees. Accurate blood glucose (BG) readings are necessary to monitor and treat this disease. Thus, obtaining voluntary samples from primates through positive reinforcement training (PRT) is critical. The current study assessed the voluntary participation of 123 chimpanzees in BG sampling and investigated factors that may contribute to individual success. All subjects participate in regular PRT sessions as part of a comprehensive behavioral management program. Basic steps involved in obtaining BG values include: voluntarily presenting a finger/toe; allowing digit disinfection; holding for the lancet device; and allowing blood collection onto a glucometer test strip for analysis. We recorded the level of participation (none, partial, or complete) when each chimpanzee was first asked to perform the testing procedure. Nearly 30% of subjects allowed the entire procedure in one session, without any prior specific training for the target behavior. Factors that affected this initial successful BG testing included sex, personality (chimpanzees rated higher on the factor “openness” were more likely to participate with BG testing), and past training performance for “present-for-injection” (chimpanzees that presented for their most recent anesthetic injection were more likely to participate). Neither age, rearing history, time since most recent anesthetic event nor social group size significantly affected initial training success. These results have important implications for captive management and training program success, underlining individual differences in training aptitude and the need for developing individual management plans in order to provide optimal care and treatment for diabetic chimpanzees in captivity.

  8. The successful experimental induction of necrotic enteritis in chickens by Clostridium perfringens: a critical review

    PubMed Central

    2012-01-01

    Necrotic enteritis (NE) is one of the most important enteric diseases in poultry and is a high cost to the industry worldwide. It is caused by avian-specific, Necrotic Enteritis Beta toxin (NetB)-producing, strains of Clostridium perfringens that also possess in common other virulence-associated genes. In Europe the disease incidence has increased since the ban on in-feed “growth promoting” antibiotics. Because of this, many recent studies of NE have focused on finding different ways to control the disease, and on understanding its pathogenesis. Frustratingly, reproduction of the disease has proven impossible for some researchers. This review describes and discusses factors known to be important in reproducing the disease experimentally, as well as other considerations in reproducing the disease. The critical bacterial factor is the use of virulent, netB-positive, strains; virulence can be enhanced by using tpeL- positive strains and by the use of young rather than old broth cultures to increase toxin expression. Intestinal damaging factors, notably the use of concurrent or preceding coccidial infection, or administration of coccidial vaccines, combined with netB-positive C. perfringens administration, can also be used to induce NE. Nutritional factors, particularly feeding high percentage of cereals containing non-starch polysaccharides (NSP) (wheat, rye, and barley) enhance disease by increasing digesta viscosity, mucus production and bacterial growth. Animal proteins, especially fish meal, enhance C. perfringens proliferation and toxin production. Other factors are discussed that may affect outcome but for which evidence of their importance is lacking. The review compares the different challenge approaches; depending on the aim of particular studies, the different critical factors can be adjusted to affect the severity of the lesions induced. A standardized scoring system is proposed for international adoption based on gross rather than histopathological

  10. Factors confounding the assessment of reflection: a critical review

    PubMed Central

    2011-01-01

    Background Reflection on experience is an increasingly critical part of professional development and lifelong learning. There is, however, continuing uncertainty about how best to put principle into practice, particularly as regards assessment. This article explores those uncertainties in order to find practical ways of assessing reflection. Discussion We critically review four problems: 1. Inconsistent definitions of reflection; 2. Lack of standards to determine (in)adequate reflection; 3. Factors that complicate assessment; 4. Internal and external contextual factors affecting the assessment of reflection. Summary To address the problem of inconsistency, we identified processes that were common to a number of widely quoted theories and synthesised a model, which yielded six indicators that could be used in assessment instruments. We arrived at the conclusion that, until further progress has been made in defining standards, assessment must depend on developing and communicating local consensus between stakeholders (students, practitioners, teachers, supervisors, curriculum developers) about what is expected in exercises and formal tests. Major factors that complicate assessment are the subjective nature of reflection's content and the dependency on descriptions by persons being assessed about their reflection process, without any objective means of verification. To counter these validity threats, we suggest that assessment should focus on generic process skills rather than the subjective content of reflection and where possible to consider objective information about the triggering situation to verify described reflections. Finally, internal and external contextual factors such as motivation, instruction, character of assessment (formative or summative) and the ability of individual learning environments to stimulate reflection should be considered.

    2010-11-01

    This article evaluates, by means of multivariate regression, critical factors influencing the collisions of motor vehicles with adult (over 17 years) cyclists that result in fatal injury of cyclists. The analysis is based on the database of the Traffic Police of Czech Republic from the time period 1995-2007. The results suggest that the most consequential categories of factors under study are: inappropriate driving speed of automobile; the head-on crash; and night-time traffic in places without streetlights. The cyclists' faults are of most serious consequence on crossroads when cyclists deny the right of way. Males are more likely to suffer a fatal injury due to a collision with a car than females. The most vulnerable age group are cyclists above 65 years. A fatal injury of a cyclist is more often driver's fault than cyclist's (598 vs. 370). In order to reduce the fatal risk, it is recommended to separate the road traffic of motor vehicles from bicyclists in critical road-sections; or, at least, to reduce speed limits there.

    Objective To determine risk factors for late-onset candidemia among infants in the neonatal intensive care unit (NICU). Study design We performed a matched case-control study from March 2001 to January 2003 in 2 level III-IV NICUs. Case subjects had candidemia diagnosed more than 48 hours after hospitalization. Control subjects (3 per case) were matched by study site, birth weight, study year, and date of enrollment. Potential risk factors included medical devices, medications, gastrointestinal (GI) pathology (congenital anomalies or necrotizing enterocolitis) and previous bacterial bloodstream infections (BSIs). Results Forty-five cases of candidemia occurred during the study period and accounted for 15% of BSIs. C. albicans caused 62% of infections (28/45); C. parapsilosis, 31% (14/45). Multivariate analysis revealed that catheter use (odds ratio [OR] = 1.06 per day of use; 95% confidence interval [CI] = 1.02 to 1.10), previous bacterial BSIs (OR = 8.02; 95% CI = 2.76 to 23.30) and GI pathology (OR = 4.57; 95% CI = 1.62 to 12.92) were significantly associated with candidemia. In all, 26/45 cases (58%) of candidemia occurred in infants who would not have qualified for fluconazole prophylaxis according to the Kaufman criteria. Conclusions We confirmed previous risk factors (catheter-days) and identified novel risk factors (previous BSI and GI pathology) for candidemia in critically ill infants that could guide future targeted antifungal prophylaxis strategies.

    Activation of cells intrinsic to the vessel wall is central to the initiation and progression of vascular inflammation. As the dominant cellular constituent of the vessel wall, vascular smooth muscle cells (VSMCs) and their functions are critical determinants of vascular disease. While factors that regulate VSMC proliferation and migration have been identified, the endogenous regulators of VSMC proinflammatory activation remain incompletely defined. The Kruppel-like family of transcription factors (KLFs) are important regulators of inflammation. In this study, we identified Kruppel-like factor 15 (KLF15) as an essential regulator of VSMC proinflammatory activation. KLF15 levels were markedly reduced in human atherosclerotic tissues. Mice with systemic and smooth muscle–specific deficiency of KLF15 exhibited an aggressive inflammatory vasculopathy in two distinct models of vascular disease: orthotopic carotid artery transplantation and diet-induced atherosclerosis. We demonstrated that KLF15 alters the acetylation status and activity of the proinflammatory factor NF-κB through direct interaction with the histone acetyltransferase p300. These studies identify a previously unrecognized KLF15-dependent pathway that regulates VSMC proinflammatory activation. PMID:23999430

    Reestablishment of vascular homeostasis following ex vivo preservation is a critical determinant of successful organ transplantation. Because the nitric oxide (NO) pathway modulates pulmonary vascular tone and leukocyte/endothelial interactions, we hypothesized that reactive oxygen intermediates would lead to decreased NO (and hence cGMP) levels following pulmonary reperfusion, leading to increased pulmonary vascular resistance and leukostasis. Using an orthotopic rat model of lung transplantation, a porphyrinic microsensor was used to make direct in vivo measurements of pulmonary NO. NO levels measured at the surface of the transplanted lung plummeted immediately upon reperfusion, with levels moderately increased by topical application of superoxide dismutase. Because cGMP levels declined in preserved lungs after reperfusion, this led us to buttress the NO pathway by adding a membrane-permeant cGMP analog to the preservation solution. Compared with grafts stored in its absence, grafts stored with supplemental 8-Br-cGMP and evaluated 30 min after reperfusion demonstrated lower pulmonary vascular resistances with increased graft blood flow, improved arterial oxygenation, decreased neutrophil infiltration, and improved recipient survival. These beneficial effects were dose dependent, mimicked by the type V phosphodiesterase inhibitor 2-o-propoxyphenyl-8-azapurin-6-one, and inhibited by a cGMP-dependent protein kinase antagonist, the R isomer of 8-(4-chlorophenylthio)guanosine 3',5'-cyclic monophosphorothioate. Augmenting the NO pathway at the level of cGMP improves graft function and recipient survival following lung transplantation.

    This paper mainly focuses on a sector transport maintenance scheme from the aspects of high plant availability. In this study, three different maintenance schemes are considered based on (1) the number of maintenance ports and (2) the insertion direction. The design study clarifies critical design factors and key engineering issues on the maintenance scheme: (1) how to support an enormous overturning force of the toroidal field coils in the large open port for sector transport and (2) define the transferring mechanism of sectors in the vacuum vessel. On reviewing these assessment factors, the sector transport using a limited number of horizontal maintenance ports is found to be a more realistic maintenance scheme. In addition, evaluating maintenance scenarios under high decay heat is proposed for the first time. The key design factors are the cool-down time in the reactor and the cooling method in the maintenance scheme to keep components under operational temperature. Based on one-dimensional heat conduction analysis, after one month cool-down time, each sector of SlimCS could be transported to the hot cell facility by gas cooling.

    Due to increased demands for greater stringency in relation to hygiene and safety issues associated with fresh food products, coupled with ever-increasing demands by retailers for cost-effective extensions to product shelf-lives and the requirement to meet consumer expectations in relation to convenience and quality, the food packaging industry has rapidly developed to meet and satisfy expectations. One of the areas of research that has shown promise, and had success, is modified atmosphere packaging (MAP). The success of MAP-fresh meat depends on many factors including good initial product quality, good hygiene from the source plants, correct packaging material selection, the appropriate gas mix for the product, reliable packaging equipment, and maintenance of controlled temperatures and humidity levels. Advances in plastic materials and equipment have propelled advances in MAP, but other technological and logistical considerations are needed for successful MAP systems for raw chilled meat. Although several parameters critical for the quality of MA packed meat have been studied and each found to be crucial, understanding of the interactions between the parameters is needed. This review was undertaken to present the most comprehensive and current overview of the widely available, scattered information about the various integrated critical factors responsible for the quality and shelf life of MA packed meat with an interest to stimulate further research to optimize different quality parameters.

    For the past five years, the New York City College of Technology has administered a successful National Science Foundation (NSF) Research Experience for Undergraduates (REU) program. The program provides rich, substantive, academic and life-transformative STEM educational experiences for students who would otherwise not pursue STEM education altogether or would not pursue STEM education through to the graduate school level. The REU Scholars are provided with an opportunity to conduct intensive satellite and ground-based remote sensing research at the National Oceanic and Atmospheric Administration Cooperative Remote Sensing Science and Technology Center (NOAA-CREST). Candidates for the program are recruited from the City University of New York's twenty-three separate campuses. These students engage in a research experience that spans the summer and the fall and spring semesters. Eighty-four percent (84%) of the program participants are underrepresented minorities in STEM, and they are involved in a plethora of undergraduate research best practice activities that include: training courses in MATLAB programming, Geographic Information Systems, and Remote Sensing; workshops in Research Ethics, Scientific Writing, and Oral and Poster Research Presentations; national, regional, and local conference presentations; graduate school support; and geoscience exposure events at national laboratories, agencies, and research facilities. To enhance their success in the program, the REU Scholars are also provided with a comprehensive series of safety nets that include a multi-tiered mentoring design specifically to address critical issues faced by this diverse population. Since the inception of the REU program in 2008, a total of 61 undergraduate students have finished or are continuing with their research or are pursuing their STEM endeavors. All the REU Scholars conducted individual satellite and ground-based remote sensing research projects that ranged from the study of

    Managing software development in large organizations has become increasingly difficult due to increasing technical complexity, stricter government standards, a shortage of experienced software engineers, competitive pressure for improved productivity and quality, the need to co-develop hardware and software together, and the rapid changes in both hardware and software technology. The 'software factory' approach to software development minimizes risks while maximizing productivity and quality through standardization, automation, and training. However, in practice, this approach is relatively inflexible when adopting new software technologies. The methods that a large multi-project software engineering organization can use to increase the likelihood of successful software technology insertion (STI), especially in a standardized engineering environment, are described.

    School success predicts many pathways for health and well-being across the life span. Factors promoting or potentially impeding school success are critical to understand for all children and for children with special health care needs (CSHCN), whose life course trajectories are already impacted by their chronic health problems. The 2007 National Survey of Children's Health was used (1) to estimate national and state prevalence and within and across states disparities in factors promoting school success (engagement, participation, safety) or potentially impeding success (missing school, grade repetition, school identified problems) for all children and CSHCN and (2) to evaluate associations with CSHCN service need complexity and presence of emotional, behavioral or developmental problems (EBD) as well as with school case management policies in states. Among school age children, 60 % experienced all three factors promoting school success (49.3-73.8 % across states), dropping to 51.3 % for CSHCN (39.4-64.7 % across states) and to 36.2 % for the 40 % of all CSHCN who have both more complex service needs and EBD. CSHCN were more likely to experience factors potentially impeding school success. After accounting for child factors, CSHCN living in states requiring case management in schools for children with disabilities were less likely to experience grade repetition (OR 0.65). Within-state disparities between non-CSHCN and CSHCN varied across states. Threats to school success for US children are pervasive and are especially pronounced for CSHCN with more complex needs and EBD. Findings support broad, non-condition specific efforts to promote school success for CSHCN and consideration of state school policies, such as case management.

  10. Factors influencing nesting success of burrowing owls in southeastern Idaho

    1985-01-31

    A burrowing owl (Athene cunicularia) population nesting on the Idaho National Engineering Laboratory (INEL) in southeastern Idaho utilized burrows excavated by badgers (Taxidea taxus) or natural cavities in lava flows as nesting sites. The size of the population was small (N = 13-14 pairs) in relation to the number of available nesting sites, suggesting that factors other than burrow availability limited this population. Rodents and Jerusalem crickets (Stenopelmatus fuscus) represented the primary prey utilized during the nesting season. This population demonstrated both a numerical (brood size) and functional (dietary) response to a decrease in the density of three species of rodents on the INEL during a drought in 1977. 11 references, 1 figure, 2 table.

    Currie, Michelle A.

    Black faculty at predominantly White institutions (PWIs) have historically been underrepresented and made to endure with academic isolation, scholarship marginalization and other challenges to the tenure process. When it comes to science, technology, engineering and math, also known as STEM, as it relates to race and success, little is known of how tenured Black STEM faculty have developed an interest in STEM, navigated the unfamiliar waters of academia and maintained longevity at their respective postsecondary institutions. The purpose of this study is to look at the similar experiences of this population and provide insight regarding any factors and or influences that have impacted their success. Grounded in critical race theory (CRT), this qualitative study will utilize a Delphi technique to determine the similar experiences and influences of 17 Black STEM, tenured (and tenure-track) faculty working at PWIs in a Southern Regional Education Board (SREB) states. The study highlighted the importance of: mentoring in college, graduate school and as a junior faculty and; STEM related opportunities such as summer camps or programs, internships, and research.

  17. Interdisciplinary collaboration: the slogan that must be achieved for models of delivering critical care to be successful.

    PubMed

    Irwin, Richard S; Flaherty, Helen M; French, Cynthia T; Cody, Shawn; Chandler, M Willis; Connolly, Ann; Lilly, Craig M

    2012-12-01

    There is wide acceptance of the concept that interdisciplinary collaboration is an essential building block for successful health-care teams. This belief is grounded in our understanding of how teams function to address complex care needs that change with acute illness or injury. This general agreement has been validated in studies that have reported favorable outcomes associated with successfully implementing interdisciplinary models of health-care delivery in non-critical care settings. The very short time frames over which the care needs of critically ill or injured adults change and the team approach taken by nearly all ICUs strongly suggest that interdisciplinary collaboration is also beneficial in this setting. In this commentary, we define interdisciplinary collaboration and share the story of how we successfully redesigned and transformed our system-wide, interdisciplinary collaborative model for delivering critical care in order to share the lessons we learned as the process evolved with those who are about to embark on a similar challenge. We anticipate that those health-care systems that successfully implement interdisciplinary collaboration will be ahead of the curve in providing high-quality care at as low a cost as possible. Such institutions will also potentially be better positioned for improving teaching and providing a better foundation for critical care research in their institutions. PMID:23208334

  18. Charting the pipeline: Identifying the critical elements in the development of successful African American scientists, engineers, and mathematicians

    NASA Astrophysics Data System (ADS)

    Williams, Brian Anthony

    Many educational researchers are concerned with the apparent poor performance of different racial and ethnic groups in the fields of science, engineering, and mathematics in the United States. Despite improvements in the performance of African Americans, Hispanic Americans, and Native Americans in these areas over the past decade, these groups are still less likely to enroll in advanced math and science courses or score at or above the proficient level in mathematics. Furthermore, these groups continue to be underrepresented in the nation's technical and scientific workforce. The purpose of this study was to identify the critical elements related to the success of African Americans in science, engineering, and mathematics. Specifically, this study was designed to answer the following questions as they pertained to African American graduate students: What factors were perceived to have contributed to the students' initial interest in science, engineering, or mathematics? What factors were perceived to have contributed to the students' decisions to continue their studies in their specific areas of interest? What factors, associated with the K--12 schooling experience, were perceived to have contributed to the students' success in science, engineering, or mathematics? The data for the study were acquired from interviews with 32 African American students (16 males and 16 females) who were engaged in graduate work in science, engineering, or mathematics. Four major themes emerged from the analysis of the interview data. The first was that all students were involved in experiences that allowed a significant level of participation in science, engineering, and mathematics. Second, all of the students experienced some form of positive personal intervention by another person. Third, all students possessed perceptions of these fields that involved some sort of positive outcome. Finally, all of the of the students believed they possessed intrinsic qualities that qualified and

    The effects of critical factors such as Henry's Law constant, atmospheric OH rate constant, initial concentration, H2O2, FeSO4 and tert-butanol on the sonochemical degradation of fumaric acid have been investigated. The pseudo first-order rate constant for the sonochemical degradation of 1mM fumaric acid is much lower than those for chloroform and phenol degradation, and is related to solute concentration at the bubble/water interface and reactivity towards hydroxyl radicals. Furthermore, fumaric acid is preferentially oxidized at the lower initial concentration. It is unreactive to H2O2 under agitation at room temperature. However, the degradation rate of fumaric acid increases with the addition of H2O2 under sonication. 0.1 mM of fumaric acid suppresses H2O2 formation thanks to water sonolysis, while degradation behavior is also dramatically affected by the addition of an oxidative catalyst (FeSO4) or radical scavenger (tert-butanol), indicating that the degradation of fumaric acid is caused by hydroxyl radicals generated during the collapse of high-energy cavities.

  3. "STEMulating" success factors: An investigation of the academic talents of successful Black male college graduates from STEM programs

    NASA Astrophysics Data System (ADS)

    Hendricks, Jill T.

    This phenomenological research study explored the contributing factors experienced by Black males that epitomized their academic success in a STEM (Science, Technology, Engineering, and Mathematics) area of study. During this investigative project, eleven Black male students were interviewed to determine how they were able to successfully navigate and complete a STEM degree. The data was collected through a qualitative inquiry, which involved interviewing students and collecting the data and organizing their perspectives into common themes. The principal findings in this study suggest that Black males can excel when primary influential people establish high expectations and believe and encourage Black males to succeed by providing the essential educational support models requisite to warrant success; the Black male maintains and affirms a self-assured self-worth in himself; the Black male is exposed to these fields and professions early on in their educational quest to enable them to witness first hand powerful and productive opportunities and pathways to academic success; exposure to other Black successful male role models who can mentor and show positive proof that with effort, these fields can become a reality; increase in academic motivation and recommendations from educators and counselors who direct and guide students into and away from these rigorous career fields. An analysis of the students' individual stories gave a revealing look into the pathways of their consciousness, emotional growth, and perspectives about being a successful STEM major. This kind of insight can be a constructive diagnostic tool for students, educators, counselors, and administrators who want to motivate and influence future students to major in STEM fields of study.

    2014-01-01

    Success factors related to the implementation of change initiatives are well documented and discussed in the management literature, but they are seldom studied in healthcare organizations engaged in multiple strategic change initiatives. The purpose of this study was to identify key success factors related to implementation of change initiatives based on rich qualitative data gathered from health leader interviews at two large health systems implementing multiple change initiatives. In-depth personal interviews with 61 healthcare leaders in the two large systems were conducted and inductive qualitative analysis was employed to identify success factors associated with 13 change initiatives. Results from this analysis were compared to success factors identified in the literature, and generalizations were drawn that add significantly to the management literature, especially to that in the healthcare sector. Ten specific success factors were identified for the implementation of change initiatives. The top three success factors were (1) culture and values, (2) business processes, and (3) people and engagement. Two of the identified success factors are unique to the healthcare sector and not found in the literature on change models: service quality and client satisfaction (ranked fourth of 10) and access to information (ranked ninth). Results demonstrate the importance of human resource functions, alignment of culture and values with change, and business processes that facilitate effective communication and access to information to achieve many change initiatives. The responses also suggest opportunities for leaders of healthcare organizations to more formally recognize the degree to which various change initiatives are dependent on one another.

  5. Permanent personhood or meaningful decline? Toward a critical anthropology of successful aging.

    PubMed

    Lamb, Sarah

    2014-04-01

    The current North American successful aging movement offers a particular normative model of how to age well, one tied to specific notions of individualist personhood especially valued in North America emphasizing independence, productivity, self-maintenance, and the individual self as project. This successful aging paradigm, with its various incarnations as active, healthy and productive aging, has received little scrutiny as to its cultural assumptions. Drawing on fieldwork data with elders from both India and the United States, this article offers an analysis of cultural assumptions underlying the North American successful aging paradigm as represented in prevailing popular and scientific discourse on how to age well. Four key themes in this public successful aging discourse are examined: individual agency and control; maintaining productive activity; the value of independence and importance of avoiding dependence; and permanent personhood, a vision of the ideal person as not really aging at all in late life, but rather maintaining the self of one's earlier years. Although the majority of the (Boston-area, well-educated, financially privileged) US elders making up this study, and some of the most cosmopolitan Indians, embrace and are inspired by the ideals of the successful aging movement, others critique the prevailing successful aging model for insufficiently incorporating attention to and acceptance of the human realities of mortality and decline. Ultimately, the article argues that the vision offered by the dominant successful aging paradigm is not only a particular cultural and biopolitical model but, despite its inspirational elements, in some ways a counterproductive one. Successful aging discourse might do well to come to better terms with conditions of human transience and decline, so that not all situations of dependence, debility and even mortality in late life will be viewed and experienced as "failures" in living well.

    2012-04-01

    We examined the factors related to success in achieving weight reduction and glycemic control in Alliance for a Healthy Border (AHB), a chronic disease prevention program implemented from 2006 to 2009 through 12 federally qualified community health centers serving primarily Hispanics in communities located along the US-Mexico border region. We analyzed data from Phase I of AHB using logistic regression to examine the determinants of success in achieving weight reduction and glycemic control among the participants in AHB programs. Factors affecting weight reduction success were sex, age, employment status, income, insurance, diabetes, baseline body mass index (BMI), smoking status, family history of diabetes, session type, program duration, and physical activity changes. Factors affecting achievement of glycemic success included sex, age, employment status, diabetes, baseline BMI, family history of diabetes, program duration, and physical activity changes. We found that the AHB interventions were more successful in reducing participants' HbA1c level than BMI. In addition to sociodemographic factors, participants with better baseline health conditions (ie, participants without diabetes or family history of diabetes, normal BMI, former smokers) were more likely to achieve success after the interventions. Of the 4 key features defining each of the 12 interventions, session type and program duration were associated with success. Within a relatively short time period, physical activity improvements had a stronger effect on weight reduction and glycemic success than improvements in dietary habits. The effectiveness of diabetes and cardiovascular disease prevention programs can be improved substantially by considering these factors during program design and structure.

    The ultimate success of reintroduction programs for endangered species depends on the ability of reintroduced animals to breed in the wild. We studied the nesting success and breeding biology of a reintroduced population of Puaiohi (Myadestes palmeri) on the island of Kaua'i, Hawaii. Thirty-four captive-bred Puaiohi were released into the Alaka'i Swamp in 1999-2001 and monitored using radiotelemetry. Ten females and two males paired with wild and other released birds, including one polygynous trio. From March to September, 31 nests were built. Mean clutch size was 2.0 eggs, daily nest survival was 0.97 ?? 0.01 (mean ?? SE) and overall nest success was 0.40 ?? 0.02. We confirmed predation, most probably by rats (Rattus spp.), as the greatest cause of nest failure, occurring at 38% of active nests with known fates, and causing the death of two nesting adult females. Ground-based rodent control proved ineffective at protecting nest attempts. Successful nests fledged an average of 1.4 young each (n = 10), and 85% of fledglings survived at least two weeks. Importantly, breeding behavior and success were comparable to those of wild Puaiohi. This is the first record of breeding in the wild from captive-bred endangered Hawaiian passerines. The ability of captive-bred Puaiohi to survive and breed successfully in the wild bodes well for future releases of this and other endangered passerines, but high predation rates on nests and nesting females highlights the importance of maintaining and restoring safe habitat for recovery. ??

  4. Premarital screening programmes for haemoglobinopathies, HIV and hepatitis viruses: review and factors affecting their success.

    PubMed

    Alswaidi, Fahad M; O'Brien, Sarah J

    2009-01-01

    This literature review is a comprehensive summary of premarital (prenuptial) screening programmes for the most prevalent hereditary haemoglobinopathies, namely thalassaemia and sickle cell disease, and the important infections HIV (human immunodeficiency virus) and hepatitis viruses B and C (HBV and HCV). It describes the background to premarital screening programmes and their value in countries where these diseases are endemic. The use of premarital screening worldwide is critically evaluated, including recent experiences in Saudi Arabia, followed by discussion of the outcomes of such programmes. Despite its many benefits, premarital testing is not acceptable in some communities for various legal and religious reasons, and other educational and cultural factors may prevent some married couples following the advice given by counsellors. The success of these programmes therefore depends on adequate religious support, government policy, education and counselling. In contrast to premarital screening for haemoglobinopathies, premarital screening for HIV and the hepatitis viruses is still highly controversial, both in terms of ethics and cost-effectiveness. In wealthy countries, premarital hepatitis and HIV testing could become mandatory if at-risk, high-prevalence populations are clearly identified and all ethical issues are adequately addressed.

  5. Pilot Critical Incident Reports as a Means to Identify Human Factors of Remotely Piloted Aircraft

    NASA Technical Reports Server (NTRS)

    Hobbs, Alan; Cardoza, Colleen; Null, Cynthia

    2016-01-01

    It has been estimated that aviation accidents are typically preceded by numerous minor incidents arising from the same causal factors that ultimately produced the accident. Accident databases provide in-depth information on a relatively small number of occurrences, however incident databases have the potential to provide insights into the human factors of Remotely Piloted Aircraft System (RPAS) operations based on a larger volume of less-detailed reports. Currently, there is a lack of incident data dealing with the human factors of unmanned aircraft systems. An exploratory study is being conducted to examine the feasibility of collecting voluntary critical incident reports from RPAS pilots. Twenty-three experienced RPAS pilots volunteered to participate in focus groups in which they described critical incidents from their own experience. Participants were asked to recall (1) incidents that revealed a system flaw, or (2) highlighted a case where the human operator contributed to system resilience or mission success. Participants were asked to only report incidents that could be included in a public document. During each focus group session, a note taker produced a de-identified written record of the incident narratives. At the end of the session, participants reviewed each written incident report, and made edits and corrections as necessary. The incidents were later analyzed to identify contributing factors, with a focus on design issues that either hindered or assisted the pilot during the events. A total of 90 incidents were reported. Human factor issues included the impact of reduced sensory cues, traffic separation in the absence of an out-the-window view, control latencies, vigilance during monotonous and ultra-long endurance flights, control station design considerations, transfer of control between control stations, the management of lost link procedures, and decision-making during emergencies. Pilots participated willingly and enthusiastically in the study

    Mother-to-child-transmission (MTCT) of HIV still remains a significant route of new HIV infection in children in Malawi and Nigeria, despite the introduction of Prevention-of-Mother-to-Child-Transmission (PMTCT) of HIV programmes in both countries. A critical literature review, based on the findings from 12 primary research articles, explores the reasons for the inadequacy and failure of PMTCT. Findings show socioeconomic and sociocultural factors as the biggest barriers to the success of PMTCT programmes. Other factors include: limited male involvement, the organization of PMTCT and health workers’ inefficiency. In conclusion, PMTCT programmes will remain inefficient unless these factors are addressed. There is an urgent need to strengthen PMTCT programmes by stakeholders through a collaborative strategic effort to ensure high PMTCT programme uptake in Malawi and Nigeria, in order to eliminate HIV/AIDS in children.

    As labor shortages intensify, succession planning and leadership development have become strategic initiatives requiring rigorous consideration. Traditional methods of replacing personnel will not accommodate the vacancies expected to plague healthcare organizations. Managers should focus on identifying potential gaps of key personnel and adapting programs to accommodate organizational need. Attention should be placed on capturing the intellectual capital existent in the organization and developing diverse groups of leadership candidates.

    Photodynamic therapy can be a highly complex treatment with more than one parameter to control, or in some cases it is easily implemented with little control other than prescribed drug and light values. The role of measured dosimetry as related to clinical adoption has not been as successful as it could have been, and part of this may be from the conflicting goals of advocating for as many measurements as possible for accurate control, versus companies and clinical adopters advocating for as few measurements as possible, to keep it simple. An organized approach to dosimetry selection is required, which shifts from mechanistic measurements in pre-clinical and early phase I trials, towards just those essential dose limiting measurements and a focus on possible surrogate measures in phase II/III trials. This essential and surrogate approach to dosimetry should help successful adoption of clinical PDT if successful. The examples of essential dosimetry points and surrogate dosimetry tools which might be implemented in phase II and higher trials are discussed for solid tissue PDT with verteporfin and skin lesion treatment with aminolevulinc acid.

  11. Factors influencing job valuation: a comparative study of critical care and non-critical care nurses.

    PubMed

    Chaboyer, W; Najman, J; Dunn, S

    2001-04-01

    This study sought to identify the relationship between three predictor variables, perceived collaboration with medical staff, autonomy and independent actions and an outcome, the value hospital nurses placed on their work. In total 189 critical care and 366 non-critical care nurses completed a mailed survey. Critical care nurses perceived themselves to have a more collaborative relationship with the medical staff, described performing actions independent of medical orders more frequently and perceived their jobs to have more value than non-critical care nurses. However the latter group perceived themselves to have more autonomy in their work. Within both groups collaboration and autonomy were significantly, but weak to moderately correlated with job valuation. Simply expanding the work hospital nurses do is unlikely to result in nurses valuing their jobs more, however promoting an environment of respect and sharing between the medical and nursing staff and supporting nurses when they act in an autonomous fashion may positively influence nurses' perceptions of their work.

    2014-08-07

    We show how to obtain the critical compressibility factor Z{sub c} for simple and associative Lennard-Jones fluids using the critical characteristics of the Ising model on different lattices. The results show that low values of critical compressibility factor are correlated with the associative properties of fluids in critical region and can be obtained on the basis of the results for the Ising model on lattices with more than one atom per cell. An explanation for the results on the critical point line of the Lennard-Jones fluids and liquid metals is proposed within the global isomorphism approach.

    The association between psychological factors and smoking cessation is complicated and inconsistent in published researches, and the joint effect of psychological factors on smoking cessation is unclear. This study explored how psychological factors jointly affect the success of smoking cessation using a Bayesian network approach. A community-based case control study was designed with 642 adult male successful smoking quitters as the cases, and 700 adult male failed smoking quitters as the controls. General self-efficacy (GSE), trait coping style (positive-trait coping style (PTCS) and negative-trait coping style (NTCS)) and self-rating anxiety (SA) were evaluated by GSE Scale, Trait Coping Style Questionnaire and SA Scale, respectively. Bayesian network was applied to evaluate the relationship between psychological factors and successful smoking cessation. The local conditional probability table of smoking cessation indicated that different joint conditions of psychological factors led to different outcomes for smoking cessation. Among smokers with high PTCS, high NTCS and low SA, only 36.40% successfully quitted smoking. However, among smokers with low pack-years of smoking, high GSE, high PTCS and high SA, 63.64% successfully quitted smoking. Our study indicates psychological factors jointly influence smoking cessation outcome. According to different joint situations, different solutions should be developed to control tobacco in practical intervention.

    Clement, James L., Jr.; Ritsher, Jennifer Boyd

    2006-01-01

    As part of its preparation for missions to the Moon and Mars, NASA has identified high priority critical path roadmap (CPR) questions, two of which focus on the performance of mission control personnel. NASA flight controllers have always worked in an incredibly demanding setting, but the International Space Station poses even more challenges than prior missions. We surveyed 14 senior ISS flight controllers and a contrasting sample of 12 more junior controllers about the management and cultural challenges they face and the most effective strategies for addressing them. There was substantial consensus among participants on some issues, such as the importance of building a personal relationship with Russian colleagues. Responses from junior and senior controllers differed in some areas, such as training. We frame the results in terms of two CPR questions. We aim to use our results to improve flight controller training.

    Successful vaginal birth after cesarean section is more comfortable than repeat emergency or elective cesarean section. Antenatal examinations are important in selection for trial of labor, while birth management can be difficult when the patients present at emergency condition. But there is an increased chance of vaginal birth with advanced cervical dilation. This study attempts to evaluate factors associated with success of vaginal birth after cesarean section and to compare the maternal and perinatal outcomes between vaginal birth after cesarean section and intrapartum cesarean section in patients who were admitted to hospital during the active or second stage of labor. A retrospective evaluation was made from the results of 127 patients. Cesarean section was performed in 57 patients; 70 attempted trial of labor. The factors associated with success of vaginal birth after cesarean section were investigated. Maternal and neonatal outcomes were compared between the groups. Vaginal birth after cesarean section was successful in 55% of cases. Advanced cervical opening, effacement, gravidity, parity, and prior vaginal delivery were factors associated with successful vaginal birth. The vaginal birth group had more complications (P<0.01), but these were minor. The rate of blood transfusion and prevalence of changes in hemoglobin level were similar in both groups (P>0.05). In this study, cervical opening, effacement, gravidity, parity, and prior vaginal delivery were important factors for successful vaginal birth after cesarean section. The patients’ requests influenced outcome. Trial of labor should take into consideration the patient’s preference, together with the proper setting. PMID:26203286

    AIM To investigate the factors that may influence the successful corneal donation among adults in China. METHODS This retrospective study was conducted in 2012. The eligible participants were all the adults registered in Nanjing Red Cross Eye Bank to donate their corneas after death during the period of 2001 and 2012. Multivariate logistic regression models were applied to investigate the influence factors for successful donation, the outcome events. RESULTS Totally, 210 of 328 (64.0%) registered potential donors successfully donated their corneas after death. The mean (SD) age at registration was 64.7 (12.5) for all participants, with 65.5 (10.1) and 63.2 (15.8) for successful and unsuccessful donors, respectively. With multivariate logistic regression analysis, five factors, the willingness of donation, age, education level, residence area, and cause of death were identified to be associated with successful corneal donation. CONCLUSION The willingness of donation and some socio-demographic factors might substantially affect their successful donation after death for people who registered to donate corneas. PMID:25540751

    Factors that influence hunter success for waterfowl are subject to varying levels of control by managers. The relative influence of these factors is poorly understood, but such information may be valuable to guide management actions intended to promote successful hunting and communicate management decisions to constituents. We used bag-check data to investigate factors influencing hunter success for mallards Anas platyrhynchos and other dabbling ducks (tribe Anatini) during the period 1981-2000 and 2002 at Illinois public waterfowl areas. Competing models of hunter success for mallards and other dabbling ducks included a negative association with average low temperature during the duck season (uncontrollable by managers) and positive associations with estimates of local and continental duck abundance, factors which we considered partially controllable by managers. Although a certain proportion of variation in hunter success for ducks cannot be directly influenced by managers, we suggest that programs and management efforts, which promote larger continental duck populations (e.g. Conservation Reserve Program) and local duck abundance (e.g. provide quality wetland foraging habitats), may positively influence hunter success.

    We examined the factors related to success in achieving weight reduction and glycemic control in Alliance for a Healthy Border (AHB), a chronic disease prevention program implemented from 2006 to 2009 through 12 federally qualified community health centers serving primarily Hispanics in communities located along the US-Mexico border region. We analyzed data from Phase I of AHB using logistic regression to examine the determinants of success in achieving weight reduction and glycemic control among the participants in AHB programs. Factors affecting weight reduction success were sex, age, employment status, income, insurance, diabetes, baseline body mass index (BMI), smoking status, family history of diabetes, session type, program duration, and physical activity changes. Factors affecting achievement of glycemic success included sex, age, employment status, diabetes, baseline BMI, family history of diabetes, program duration, and physical activity changes. We found that the AHB interventions were more successful in reducing participants' HbA1c level than BMI. In addition to sociodemographic factors, participants with better baseline health conditions (ie, participants without diabetes or family history of diabetes, normal BMI, former smokers) were more likely to achieve success after the interventions. Of the 4 key features defining each of the 12 interventions, session type and program duration were associated with success. Within a relatively short time period, physical activity improvements had a stronger effect on weight reduction and glycemic success than improvements in dietary habits. The effectiveness of diabetes and cardiovascular disease prevention programs can be improved substantially by considering these factors during program design and structure. PMID:22506803

  8. Safer approaches and landings: A multivariate analysis of critical factors

    NASA Astrophysics Data System (ADS)

    Heinrich, Durwood J.

    The approach-and-landing phases of flight represent 27% of mission time while resulting in 61 of the accidents and 39% of the fatalities. The landing phase itself represents only 1% of flight time but claims 45% of the accidents. Inadequate crew situation awareness (SA), crew resource management (CRM), and crew decision-making (DM) have been implicated in 51%, 63%, and 73% respectively of these accidents. The human factors constructs of SA, CRM, and DM were explored; a comprehensive definition of SA was proposed; and a "proactive defense" safety strategy was recommended. Data from a 1997 analysis of worldwide fatal accidents by the Flight Safety Foundation (FSF) Approach-and-Landing Accident Reduction (ALAR) Task Force was used to isolate crew- and weather-related causal factors that lead to approach-and-landing accidents (ALAs). Logistic regression and decision tree analysis were used on samplings of NASA's Aviation Safety Reporting System (ASRS) incident records ("near misses") and the National Transportation Safety Board's (NTSB) accident reports to examine hypotheses regarding factors and factor combinations that can dramatically increase the opportunity for accidents. An effective scale of risk factors was introduced for use by crews to proactively counter safety-related error-chain situations.

    The critical components of clean-room and barrier isolator systems are described. Cleanroom and barrier isolator systems have four basic parts: the physical structure, the internal environment, the interaction technology, and the monitoring system. To create an aseptic environment, pharmacists must understand each of these components and be able to provide vendors with clear specifications. Among the decisions pharmacists must make are what materials should be used in construction, how many filters to use and where these should be placed, how to best reduce the contamination challenge to the area, and the best means of monitoring the room's air cleanliness. Evaluation of each component should be made on the basis of durability, functionality, and cost. Pharmacists must also have a set of criteria to help them choose a vendor. They must know their state's requirements and ensure that whatever system is built for their organization will meet all regulations. Cleanroom and barrier isolator systems must adhere to Federal Standard 209E, which defines standard classes of air cleanliness that are based on specific concentrations and sizes of airborne particles. Having an understanding of the basic components of cleanroom and barrier isolator systems will help pharmacists define their needs and describe them to vendors.

    Vancomycin is a glycopeptide antibiotic commonly used in the management of methicillin-resistant Staphylococcus aureus infection. The recent increase in prevalence of methicillin-resistant Staphylococcus aureus with reduced susceptibility to vancomycin has prompted experts to advocate for higher target trough serum concentrations. This study aimed to evaluate the potential consequences of more aggressive vancomycin therapy, by examining the association between higher serum concentrations and acute kidney injury (AKI) in a population of critically ill patients. We collected data for all patients who received vancomycin over a five-year period and evaluated the prevalence of new-onset AKI using the Risk, Injury, Failure, Loss and End-stage (RIFLE) kidney disease criteria. One-hundred and fifty-nine patients provided complete data, with 8.8% manifesting new onset AKI while receiving vancomycin. The median age was 57 (44 to 68) years, while the median trough serum concentration was 16 (10 to 19) mg/l. Multivariate logistic regression analysis identified mean trough concentration (OR=1.174, P=0.024), APACHE II score (OR=1.141, P=0.012) and simultaneous aminoglycoside prescription (OR=18.896, P=0.002) as significant predictors of AKI. These data suggest higher trough vancomycin serum concentrations are associated with greater odds of AKI in the critically ill.

    Miniscrews offer a reliable alternative for anchorage during orthodontic treatment, particularly for non-cooperative patients or periodontal patients with alveolar bone loss. The study aims at assessing the correlation of various clinical indicators with the success or failure of miniscrews used for anchorage during orthodontic treatment. Thirty-four consecutive patients with a cumulative total of 82 miniscrews implanted participated in the study. Generalized Estimating Equations were used to assess the correlation of various factors with success rates. The miniscrew was considered the unit of analysis clustered within site and within patient. The overall success rate of miniscrews was 90.2%. For every additional miniscrew used in a patient's oral cavity, the success rate was reduced by 67%. Retromandibular triangle and palatal placement and in movable mucosa resulted in lower success rate. The miniscrew length and diameter were found to correlate with success rates. Orthodontic force applied on miniscrews for uprighting purposes showed a lower success rate than that used for retraction. This study revealed that miniscrews present high success rates. The number of miniscrews used per patient, the miniscrew site placement, the soft tissue type of placement, the miniscrew length and diameter as well as the orthodontic force applied on the miniscrew showed significant correlation with success rates.

    2013-01-01

    Clonal growth can be a double-edged sword for endangered species, because the short-term insurance against extinction may incur a longer-term hazard of creating small inbred populations with low fecundity. In the present study, we quantify the advantages and disadvantages of clonal growth regarding the fitness of the central Iberian monotypic endangered genus Pseudomisopates. Preliminary studies showed that the species is self-incompatible and exhibits extensive clonal growth with plants flowering profusely. However, seeds at many sites seemed to be unviable, and no seedlings have been observed in the field. A fully replicated nested sampling design (n = 100) was conducted to explore genetic (using seven SSR loci) and environmental factors potentially affecting seed viability, such as: 1) clonal and genetic diversity, 2) spatial genetic structure, and 3) environmental factors (shrub cover and grazing). Generalized Linear Mixed Models were fitted relating genetic and environmental variables to reproductive variables (seed viability and flower display). Our results indicate that the relatively low genotypic diversity of the population (PD = 0.23), as quantified by SSRs, and the strong spatial genetic structure observed are congruent with intense clonal growth. This clonal growth is enhanced by unfavorable environmental conditions, such as canopy closure and grazing. Under these circumstances, both flower display and mate availability decrease, thus hindering sexual reproduction. Indeed, a mixed reproductive system (clonal and sexual) to escape environmental stochasticity is crucial for the survival of Pseudomisopates, a species inhabiting a disturbance-prone ecosystem.

    Objective To systematically review previous studies and to assess, via a subgroup meta-analysis, the combined odds ratio (OR) of prognostic factors affecting the success of miniscrew implants (MIs) inserted into the buccal posterior region. Methods Three electronic searches that were limited to articles on clinical human studies using MIs that were published in English prior to March 2015 were conducted. The outcome measure was the success of MIs. Patient factors included age, sex, and jaw of insertion (maxilla vs. mandible), while the MI factors included length and diameter. A meta-analysis was performed on 17 individual studies. The quality of each study was assessed for non-randomized studies and quantified using the Newcastle-Ottawa Scale. The meta-analysis outcome was a combined OR. Subgroup and sensitivity analyses based on the study design, study quality, and sample size of miniscrews implanted were performed. Results Significantly higher success rates were revealed for MIs inserted in the maxilla, for patients ≥ 20 years of age, and for long MIs (≥ 8 mm) and MIs with a large diameter (> 1.4 mm). All subgroups acquired homogeneity, and the combined OR of the prospective studies (OR, 3.67; 95% confidence interval [CI], 2.10-6.44) was significantly higher in the maxilla than that in the retrospective studies (OR, 2.10; 95% CI, 1.60-2.74). Conclusions When a treatment plan is made, these risk factors, i.e. jaw of insertion, age, MI length, and MI diameter, should be taken into account, while sex is not critical to the success of MIs.

    2013-01-01

    Introduction Breast cancer remains a significant scientific, clinical and societal challenge. This gap analysis has reviewed and critically assessed enduring issues and new challenges emerging from recent research, and proposes strategies for translating solutions into practice. Methods More than 100 internationally recognised specialist breast cancer scientists, clinicians and healthcare professionals collaborated to address nine thematic areas: genetics, epigenetics and epidemiology; molecular pathology and cell biology; hormonal influences and endocrine therapy; imaging, detection and screening; current/novel therapies and biomarkers; drug resistance; metastasis, angiogenesis, circulating tumour cells, cancer ‘stem’ cells; risk and prevention; living with and managing breast cancer and its treatment. The groups developed summary papers through an iterative process which, following further appraisal from experts and patients, were melded into this summary account. Results The 10 major gaps identified were: (1) understanding the functions and contextual interactions of genetic and epigenetic changes in normal breast development and during malignant transformation; (2) how to implement sustainable lifestyle changes (diet, exercise and weight) and chemopreventive strategies; (3) the need for tailored screening approaches including clinically actionable tests; (4) enhancing knowledge of molecular drivers behind breast cancer subtypes, progression and metastasis; (5) understanding the molecular mechanisms of tumour heterogeneity, dormancy, de novo or acquired resistance and how to target key nodes in these dynamic processes; (6) developing validated markers for chemosensitivity and radiosensitivity; (7) understanding the optimal duration, sequencing and rational combinations of treatment for improved personalised therapy; (8) validating multimodality imaging biomarkers for minimally invasive diagnosis and monitoring of responses in primary and metastatic disease

    2002-03-01

    This study was conducted to determine factors that promote success in an introductory college computer science course and to determine what, if any, differences appear between genders on those factors. The model included math background, attribution for success/failure, self-efficacy, encouragement, comfort level in the course, work style preference, previous programming experience, previous non-programming computer experience, and gender as possible predictive factors for success in the computer science course. Subjects included 105 students enrolled in an introductory computer science course. The study revealed three predictive factors in the following order of importance: comfort level (with a positive influence), math background (with a positive influence), and attribution to luck (with a negative influence). No significant gender differences were found in these three factors. The study also revealed that both a formal class in programming (which had a positive correlation) and game playing (which had a negative correlation) were predictive of success. The study revealed a significant gender difference in game playing with males reporting more experience with playing games on the computer than females reported.

  17. Two-factor theory, the actor-critic model, and conditioned avoidance.

    PubMed

    Maia, Tiago V

    2010-02-01

    Two-factor theory (Mowrer, 1947, 1951, 1956) remains one of the most influential theories of avoidance, but it is at odds with empirical findings that demonstrate sustained avoidance responding in situations in which the theory predicts that the response should extinguish. This article shows that the well-known actor-critic model seamlessly addresses the problems with two-factor theory, while simultaneously being consistent with the core ideas that underlie that theory. More specifically, the article shows that (1) the actor-critic model bears striking similarities to two-factor theory and explains all of the empirical phenomena that two-factor theory explains, in much the same way, and (2) there are subtle but important differences between the actor-critic model and two-factor theory, which result in the actor-critic model predicting the persistence of avoidance responses that is found empirically.

Managing change is aimed at redirecting the impact of any transformation process in the organizations towards a positive attitude and enthusiasm of those involved. That is, this paper analyzes the most important of all factors that must be managed in any project for change: the human factor. If a proper change management is a critical success factor in implementing new processes and systems of information and communication technologies (ICT) in an organization, when we faced with the introduction of new processes and interoperability systems between different organizations, cooperation, leadership and motivation of individuals focused on a common goal is absolutely imperative. This is the case of the new ICT systems being introduced in the Catalan Health System. Indeed, by definition of the model itself, in Catalonia, continuity of care, increased efficiency and effectiveness and quality improvement of projects as the clinical history shared, electronic prescriptions, or scanning medical imaging, require necessarily the definition of processes in which a large number of different health organizations, different in their law status, and whose own interests should converge towards the ICT systems and processes of health care so that the contribution of all parties can make a whole. The success of these projects, a reality nowadays, is due largely to the management of the human factor conducted continuously since its inception.

    Large-scale DNA barcoding projects are now moving toward activation while the creation of a comprehensive barcode library for eukaryotes will ultimately require the acquisition of some 100 million barcodes. To satisfy this need, analytical facilities must adopt protocols that can support the rapid, cost-effective assembly of barcodes. In this paper we discuss the prospects for establishing high volume DNA barcoding facilities by evaluating key steps in the analytical chain from specimens to barcodes. Alliances with members of the taxonomic community represent the most effective strategy for provisioning the analytical chain with specimens. The optimal protocols for DNA extraction and subsequent PCR amplification of the barcode region depend strongly on their condition, but production targets of 100K barcode records per year are now feasible for facilities working with compliant specimens. The analysis of museum collections is currently challenging, but PCR cocktails that combine polymerases with repair enzyme(s) promise future success. Barcode analysis is already a cost-effective option for species identification in some situations and this will increasingly be the case as reference libraries are assembled and analytical protocols are simplified.

    In Atlantic salmon, as in most salmonids, males can mature early in the life cycle, as small freshwater fish, termed parr, and/or undergo a sea migration before maturing as full-size adults. The alternative life histories are contingent on environmental and social circumstances, such as growth rate, territory quality or any other factor that affects the individual's state. In order to model the choice of life history in this group of commercially valuable species, it is necessary to understand not only the relative contribution of the different male types to subsequent generations, but also to know the factors that affect reproductive success in each type. In this paper we present the results of a study designed to investigate the factors that affect the reproductive success of mature parr. We used highly polymorphic minisatellite DNA markers to analyse paternity in a series of mating experiments where the number and body size of parr were manipulated. The fraction of eggs fertilized by mature parr ranged from 26 to 40 per cent, with individual parr fertilizing up to 26 per cent of the eggs. A strong positive correlation was found between parr size and reproductive success. The relative success of parr decreased with increasing parr number. Data from this and other studies on variation in the timing and degree of parr reproductive success are discussed in relation to the evolution of male mating strategies and life history in salmonids.

    From 2007 through 2014, the authors participated in the implementation of open source hospital information systems (HIS) in 19 hospitals in Rwanda, Burundi, DR Congo, Congo-Brazzaville, Gabon, and Mali. Most of these implementations were successful, but some failed. At the end of a seven-year implementation effort, a number of risk factors, facilitators, and pragmatic approaches related to the deployment of HIS in Sub-Saharan health facilities have been identified. Many of the problems encountered during the HIS implementation process were not related to technical issues but human, cultural, and environmental factors. This study retrospectively evaluates the predictive value of 14 project failure factors and 15 success factors in HIS implementation in the Sub-Saharan region. Nine of the failure factors were strongly correlated with project failure, three were moderately correlated, and one weakly correlated. Regression analysis also confirms that eight factors were strongly correlated with project success, four moderately correlated, and two weakly correlated. The study results may help estimate the expedience of future HIS projects. PMID:26262097

    The Yucatán Peninsula in Mexico contains some of the largest breeding groups of the globally distributed and critically endangered hawksbill turtle (Eretmochelys imbricata). An improved understanding of the breeding system of this species and how its genetic variation is structured among nesting areas is required before the threats to its survival can be properly evaluated. Here, we genotype 1195 hatchlings and 41 nesting females at 12 microsatellite loci to assess levels of multiple paternity, genetic variation and whether individual levels of homozygosity are associated with reproductive success. Of the 50 clutches analyzed, only 6% have multiple paternity. The distribution of pairwise relatedness among nesting localities (rookeries) was not random with elevated within-rookery relatedness, and declining relatedness with geographic distance indicating some natal philopatry. Although there was no strong evidence that particular rookeries had lost allelic variation via drift, younger turtles had significantly lower levels of genetic variation than older turtles, suggesting some loss of genetic variation. At present there is no indication that levels of genetic variation are associated with measures of reproductive success such as clutch size, hatching success, and frequency of infertile eggs.

    Foraging success for pelagic vertebrates may be revealed by horizontal and vertical movement patterns. We show markedly different patterns for leatherback turtles in the North Atlantic versus Eastern Pacific, which feed on gelatinous zooplankton that are only occasionally found in high densities. In the Atlantic, travel speed was characterized by two modes, indicative of high foraging success at low speeds (<15 km d−1) and transit at high speeds (20–45 km d−1). Only a single mode was evident in the Pacific, which occurred at speeds of 21 km d−1 indicative of transit. The mean dive depth was more variable in relation to latitude but closer to the mean annual depth of the thermocline and nutricline for North Atlantic than Eastern Pacific turtles. The most parsimonious explanation for these findings is that Eastern Pacific turtles rarely achieve high foraging success. This is the first support for foraging behaviour differences between populations of this critically endangered species and suggests that longer periods searching for prey may be hindering population recovery in the Pacific while aiding population maintenance in the Atlantic.

    Background. This study aims to verify if the presence and severity of perinatal depression are related to any particular pattern of attachment. Methods. The study started with a screening of a sample of 453 women in their third trimester of pregnancy, who were administered a survey data form, the Edinburgh Postnatal Depression Scale (EPDS) and the Experience in Close Relationship (ECR). A clinical group of subjects with perinatal depression (PND, 89 subjects) was selected and compared with a control group (C), regarding psychopathological variables and attachment patterns. Results. The ECR showed a prevalence of "Fearful-Avoidant" attachment style in PND group (29.2% versus 1.1%, p < 0.001); additionally, the EPDS average score increases with the increasing of ECR dimensions (Avoidance and Anxiety). Conclusion. The severity of depression increases proportionally to attachment disorganization; therefore, we consider attachment as both an important risk factor as well as a focus for early psychotherapeutic intervention.

    The study explores the perceptions of physicians and hospital managers regarding the key success factors (KSFs) of a clinical knowledge management system (CKMS). It aims to eliminate the perception gap and gain more insights for a successful CKMS.A survey was conducted in four medical centers in Taiwan. A total of 340 questionnaires, including 15 for hospital managers and 70 for physicians in each hospital, were administered. The effective response rates are 78.3% and 56.1% respectively. Partial least square (PLS) were used to analyze the data.The results identified six KSFs of CKMS including system software and hardware, knowledge quality, system quality, organizational factors, user satisfaction, and policy factors. User satisfaction and policy factors have direct effects on perceived CKMS performance. Knowledge quality is regarded as an antecedent to user satisfaction, while system quality is the antecedent to both user satisfaction and policy factors. System software and hardware was supported only by managers, and organizational factors were supported only by physicians.Among the factors, this study highlighted the policy factor. Besides, the study provides hospital managers additional insights into physician requirements for organizational support. Third, more physician participation and involvement are recommended when introducing and developing a CKMS.

    The purpose of this study was to identify and describe factors associated with successful university teaching within the cultural norms of a public university in the midwestern United States. An interpretive analysis was conducted using the educational philosophy and goal statements of 35 university professors who received Presidential Teaching Awards from the university. The professors' diverse disciplines included nursing, curriculum and instruction, accountancy, music, and political science. The authors offer nursing educators the opportunity to increase their confidence and effectiveness by "learning" from faculty members who have been recognized as exceptionally successful in teaching. Four main relevant themes associated with successful university teaching were identified: Presence, Promotion of Learning, Teachers as Learners, and Enthusiasm. The narratives of the professors helped define the meaning of successful teaching across disciplines and offer nursing faculty additional perspectives and experiences.

    Clinical decision support interventions are typically heterogeneous in nature, making it difficult to identify why some interventions succeed while others do not. One approach to identify factors important to the success of health information systems is the use of meta-regression techniques, in which potential explanatory factors are correlated with the outcome of interest. This approach, however, can result in misleading conclusions due to several issues. In this manuscript, we present a cautionary case study in the context of clinical decision support systems to illustrate the limitations of this type of analysis. We then discuss implications and recommendations for future work aimed at identifying success factors of medical informatics interventions. In particular, we identify the need for head-to-head trials in which the importance of system features is directly evaluated in a prospective manner. PMID:25998518

    Current understanding of the factors influencing hawksbill sea turtle (Eretmochelys imbricata) hatch success is disparate and based on relatively short-term studies or limited sample sizes. Because global populations of hawksbills are heavily depleted, evaluating the parameters that impact hatch success is important to their conservation and recovery. Here, we use data collected by the Jumby Bay Hawksbill Project (JBHP) to investigate hatch success. The JBHP implements saturation tagging protocols to study a hawksbill rookery in Antigua, West Indies. Habitat data, which reflect the varied nesting beaches, are collected at egg deposition, and nest contents are exhumed and categorized post-emergence. We analyzed hatch success using mixed-model analyses with explanatory and predictive datasets. We incorporated a random effect for turtle identity and evaluated environmental, temporal and individual-based reproductive variables. Hatch success averaged 78.6% (SD: 21.2%) during the study period. Highly supported models included multiple covariates, including distance to vegetation, deposition date, individual intra-seasonal nest number, clutch size, organic content, and sand grain size. Nests located in open sand were predicted to produce 10.4 more viable hatchlings per clutch than nests located >1.5 m into vegetation. For an individual first nesting in early July, the fourth nest of the season yielded 13.2 more viable hatchlings than the initial clutch. Generalized beach section and inter-annual variation were also supported in our explanatory dataset, suggesting that gaps remain in our understanding of hatch success. Our findings illustrate that evaluating hatch success is a complex process, involving multiple environmental and individual variables. Although distance to vegetation and hatch success were inversely related, vegetation is an important component of hawksbill nesting habitat, and a more complete assessment of the impacts of specific vegetation types on hatch

    2010-05-01

    A review of my education and 30 year career at the U.S. Geological Survey (USGS), starting as a field assistant in 1979 to becoming Chief Scientist for Geology in 2001, reveals some of the critical success factors for women in the geosciences as well as factors that inhibit success. Women comprised 5% of the geosciences workforce when I started as an undergraduate in 1975, so why did I pursue the geosciences? A high school course covering earth and biological field science was taught by an excellent teacher who encouraged me to pursue geology. In college, several factors influenced my continuation in geology: two supportive mentors, an earth science department providing a broad diversity of courses; opportunities to take graduate courses, interaction with graduate students, and doing an undergraduate thesis. Most important was the individual attention given to undergraduates by both faculty and graduates regardless of gender. The summer intern program sponsored by the National Association of Geology Teachers and the USGS was a deciding factor to my becoming a geoscientist in the public service. Family and job concerns made it difficult to complete a doctorate however, and there existed gender bias against women conducting field work. Critical factors for success at USGS included: dealing ethically, openly, and immediately with gender-biased behavior, taking on responsibilities and science projects out of my "comfort zone", having the support of mentors and colleagues, and always performing at the highest level. In the past 15 years, there have been many "first" women in various leadership roles within the USGS, and now, after 131 years, we have the first woman Director. It is important to note that as gender barriers are broken at the upper levels in an organization, it paves the way for others. Statistics regarding women are improving in terms of percentage of enrollment in degrees and jobs in the private, public, and academic sectors. Women, however, still bear

    There has been increased interest in the analysis of protein biomarkers in clinical tumor tissues in recent years. Tissue-based biomarker assays can add value and aid decision-making at all stages of drug development, as well as being developed for use as predictive biomarkers and for patient stratification and prognostication in the clinic. However, there must be an awareness of the legal and ethical issues related to the sourcing of human tissue samples. This article also discusses the limits of scope and critical aspects on the successful use of the following tissue-based methods: immunohistochemistry, tissue microarrays and automated image analysis. Future advances in standardization of tissue biobanking methods, immunohistochemistry and quantitative image analysis techniques are also discussed. PMID:21473728

    Application of next-generation sequencing (NGS) technology to routine clinical practice has enabled characterization of personalized cancer genomes to identify patients likely to have a response to targeted therapy. The proper selection of tumor sample for downstream NGS based mutational analysis is critical to generate accurate results and to guide therapeutic intervention. However, multiple pre-analytic factors come into play in determining the success of NGS testing. In this review, we discuss pre-analytic requirements for AmpliSeq PCR-based sequencing using Ion Torrent Personal Genome Machine (PGM) (Life Technologies), a NGS sequencing platform that is often used by clinical laboratories for sequencing solid tumors because of its low input DNA requirement from formalin fixed and paraffin embedded tissue. The success of NGS mutational analysis is affected not only by the input DNA quantity but also by several other factors, including the specimen type, the DNA quality, and the tumor cellularity.

  13. Women of science, technology, engineering, and mathematics: A qualitative exploration into factors of success

    NASA Astrophysics Data System (ADS)

    Olund, Jeanine K.

    Although the number of women entering science, technology, engineering, and mathematics (STEM) disciplines has increased in recent years, overall there are still more men than women completing four-year degrees in these fields, especially in physics, engineering, and computer science. At higher levels of education and within the workplace, the number of women declines even further and the attrition rate is high. Studies to explain this phenomenon abound and remedial action has been taken in many institutions. Nonetheless, the problem remains. There are women who have entered this environment, however, who are not only surviving but thriving. Through the lens of positive scholarship, this qualitative study explores characteristics of twelve high-achieving women of STEM to discover if there are common factors that have contributed to their success. The data show that successful women of STEM are enterprising, relational, self-aware, and have a positive perspective. These results suggest that the four factors, particularly through their juxtaposition, are foundational to the success of STEM women within the current culture of science. Furthermore, the behaviors, responses, and values of these women have likely contributed to systemic changes within their immediate environments and perhaps even beyond. Research has shown that positive behaviors and values can be adopted by others and integrated deeply into their psyches. Therefore, the women of this study, and others like them, could serve as role models for colleagues and peers to support the development of these factors of success in others. Women, and men, of STEM may thereby learn new ways to approach difficulties, to create new avenues for success, and to bring forth positive change within themselves and their environments.

    In the past thirty years there has been a significant increase in the number of women pursuing careers in the biological sciences, yet similar increases have not been seen in the physical sciences or engineering. Research suggests that societal, educational, and personal factors may be the cause. This study was designed to validate factors previously identified as being influential on the learning of science by women, as well as to discover factors not previously identified and to gain an understanding of the degree to which each of these factors is perceived to relate to their academic success. Quantitative and qualitative methodologies were used to identify factors that facilitated the success of or presented obstacles to women as they pursued doctoral degrees in physical science and engineering. Sixty-four women scientists completed surveys. Of these, twelve participated in telephone interviews. The data collected from these methodologies, when taken together, allowed for both a generalizability of results and in-depth understanding of the factors identified. Three major themes were identified. First was the importance of people in these women's lives. Second was each woman's expression of personality traits including passion, determination, and resilience. Third was the importance of support from a variety of sources. All of the scientists considered support necessary for their success. Implications for practice include: providing girls with a wide variety of experiences in mathematics and science, including both in-school and out-of-school activities; providing girls with role models and mentors; utilizing a variety of teaching strategies aimed at girls' preferred learning styles; providing a variety of kinds of support girls need to feel welcome and valued; developing in girls personal characteristics associated with the culture of science; minimizing the use of high-stakes exams; and maximizing schedule flexibility so women can combine scientific careers and

    This article explores the key factors for successful employment from the viewpoints of adults with autism spectrum disorder (ASD) and employers. Two groups of individuals participated in this study, 40 adults with ASD and 35 employers. Q method was used to understand and contrast the viewpoints of the two groups. Data were analysed using by-person varimax rotation factor analysis. Results showed that although both groups appear committed to the employment process, the difference in their understanding regarding the type of workplace support required, job expectations and productivity requirements continues to hinder successful employment. These results highlight the need to facilitate communication between employees and employers to ensure a clear understanding of the needs of both groups are met. The use of an ASD-specific workplace tool may assist in facilitating the necessary communication between these two groups.

    2003-01-01

    Even though the balanced scorecard (BSC) has become a highly popular performance management tool, usage in local public sector National Health Service (NHS) organisations is still rare. This paper conditionally outlines some grounds in supporting such usage. In particular underlying conceptual concerns with the BSC system and its implementation pitfalls require full consideration. This paper then outlines some factors to be taken into account for "successful" BSC implementation in a NHS multi-agency setting. These findings emerged from a series of focus groups that took place with contributors drawn from all the key organisations within the Bradford Health Action Zone. Finally, this paper argues that if key criteria are met, successful implementation of the BSC may then proceed. However, "blind" BSC implementation without consideration of these factors may result in potential "failure". PMID:12870249

    The electron paramagnetic resonance technique of double electron-electron resonance (DEER) was used to measure nanometre-scale distances between nitroxide spin labels attached to the complement regulatory protein CD55 (also known as decay accelerating factor) and the von Willebrand factor A (vWF-A) domain of factor B. Following a thorough assessment of the quality of the data, distances obtained from good-quality measurements are compared to predicted distances from a previously hypothesised model for the complex and are found to be incompatible. The success of using these distances as restraints in multi-body docking routines is presented critically.

    OBJECTIVE: To assess and compare factors which may be associated with successful contact tracing in patients with gonorrhoea and chlamydia. STUDY DESIGN: Prospective observational study of patients attending a genitourinary medicine clinic with a diagnosis of gonorrhoea or chlamydia. Multivariate analysis model including demographic, socioeconomic, and behavioural variables. RESULTS: The attendance of at least one sexual contact was associated with naming more contacts for patients with gonorrhoea (OR 1.44, 95% CI 1.04-2.01). A history of gonorrhoea was associated with successful contact tracing for patients with chlamydia (OR 1.46, 95% CI 1.12-1.9). Successful contact tracing, as defined by at least one confirmed contact attendance after the index case, was not associated with age, sex, sexual orientation, history of chlamydia, use of condoms, marital status, ethnicity, or socioeconomic status for either gonorrhoea or chlamydia. CONCLUSIONS: Differences in the composition of the core groups infected with gonorrhoea and chlamydia are not explained by differences in contact tracing success. In the clinic setting studied, the outcome of contact tracing was not associated with a variety of demographic, socioeconomic, and behaviour factors.

    Forecast of success with testicular sperm extraction and intracytoplasmic sperm injection (ICSI) remains unknown, as predictive factors have rarely been studied. We evaluated the association among possible predictive factors and a successful biopsy and clinical pregnancy. A consecutive sample of men submitted to a testicular open biopsy in S. João Hospital was used. Patient's age, medical history, testicular volume, spermogram, genetic testing, endocrinologic results, biopsy results and clinical pregnancy information were collected. From the 113 men included, it was possible to retrieve spermatozoa in 79.6% of the cases, which resulted in 58 fertilisations and 22 clinical pregnancies. Retrieving viable spermatozoa on biopsy was associated with the identification of spermatozoa in the spermogram (100.0% versus 74.4%; P = 0.010), diseases causing obstructive infertility (100.0% versus 79.2%; P = 0.036) and no genetic causes detected (82.4% versus 54.5%; P = 0.030). Successful clinical pregnancy was only associated with lower female partner age (31.7 versus 36.0 year; P = 0.001) but not the quality of the spermatozoa or the time until the reproduction cycle. Identification of spermatozoa in the spermogram, diseases causing obstructive infertility and lack of genetic causes for infertility were associated with higher probability of viable spermatozoa retrieval but the female partner age remained the principal determinant of a successful pregnancy.

    The aim of this study was to identify common factors relating to the academic success of medical students who were distinguished with honors at the Buenos Aires University. In 2011, 142 graduates were surveyed; the questionnaire included 59 questions on their sociodemographic environment, living conditions and social integration, motivation to study, learning capacity and health quality during their career. Compared to other students, these distinguished students more often lived in the city, far from their families; had been educated at private or universitary high schools, their economic needs were financed by their parents, who were on the whole professionals. Most of them were single and childless. The possibility of future employment oportunities (work) did not influence their choice of a medical career, academic success was important to them and they believed that success depended largely on personal effort; they knew how to handle anxiety, were sociable but independent and preferred solid experience to abstract conceptuality in order to obtain information. Our conclusion, within the current system of candidate selection, these results serve to calculate the covert self-selection mechanisms during the career, or in a more restrictive regime, to select those likely to reach academic success due to their privileged ambience. The analysis of demographic factors indicates some degree of inequality for socially disadvantaged students. Perhaps, a selection system based only on intellectual abilities would help identify and support the best candidates regardless of their social context. PMID:25555005

  10. Methods for detrending success metrics to account for inflationary and deflationary factors*

    NASA Astrophysics Data System (ADS)

    2011-01-01

    Time-dependent economic, technological, and social factors can artificially inflate or deflate quantitative measures for career success. Here we develop and test a statistical method for normalizing career success metrics across time dependent factors. In particular, this method addresses the long standing question: how do we compare the career achievements of professional athletes from different historical eras? Developing an objective approach will be of particular importance over the next decade as major league baseball (MLB) players from the "steroids era" become eligible for Hall of Fame induction. Some experts are calling for asterisks (*) to be placed next to the career statistics of athletes found guilty of using performance enhancing drugs (PED). Here we address this issue, as well as the general problem of comparing statistics from distinct eras, by detrending the seasonal statistics of professional baseball players. We detrend player statistics by normalizing achievements to seasonal averages, which accounts for changes in relative player ability resulting from a range of factors. Our methods are general, and can be extended to various arenas of competition where time-dependent factors play a key role. For five statistical categories, we compare the probability density function (pdf) of detrended career statistics to the pdf of raw career statistics calculated for all player careers in the 90-year period 1920-2009. We find that the functional form of these pdfs is stationary under detrending. This stationarity implies that the statistical regularity observed in the right-skewed distributions for longevity and success in professional sports arises from both the wide range of intrinsic talent among athletes and the underlying nature of competition. We fit the pdfs for career success by the Gamma distribution in order to calculate objective benchmarks based on extreme statistics which can be used for the identification of extraordinary careers.

  11. Success Factors of European Syndromic Surveillance Systems: A Worked Example of Applying Qualitative Comparative Analysis

    2016-01-01

    Introduction Syndromic surveillance aims at augmenting traditional public health surveillance with timely information. To gain a head start, it mainly analyses existing data such as from web searches or patient records. Despite the setup of many syndromic surveillance systems, there is still much doubt about the benefit of the approach. There are diverse interactions between performance indicators such as timeliness and various system characteristics. This makes the performance assessment of syndromic surveillance systems a complex endeavour. We assessed if the comparison of several syndromic surveillance systems through Qualitative Comparative Analysis helps to evaluate performance and identify key success factors. Materials and Methods We compiled case-based, mixed data on performance and characteristics of 19 syndromic surveillance systems in Europe from scientific and grey literature and from site visits. We identified success factors by applying crisp-set Qualitative Comparative Analysis. We focused on two main areas of syndromic surveillance application: seasonal influenza surveillance and situational awareness during different types of potentially health threatening events. Results We found that syndromic surveillance systems might detect the onset or peak of seasonal influenza earlier if they analyse non-clinical data sources. Timely situational awareness during different types of events is supported by an automated syndromic surveillance system capable of analysing multiple syndromes. To our surprise, the analysis of multiple data sources was no key success factor for situational awareness. Conclusions We suggest to consider these key success factors when designing or further developing syndromic surveillance systems. Qualitative Comparative Analysis helped interpreting complex, mixed data on small-N cases and resulted in concrete and practically relevant findings. PMID:27182731

    The aim of the study was to determine the possible predictive value of certain patient- and stone-related factors on the stone-free rates and auxiliary procedures after extracorporeal shock wave lithotripsy in patients with impacted proximal ureteral calculi. A total of 111 patients (86 male, 25 females M/F: 3.44/1) with impacted proximal ureteral stones treated with shock wave lithotripsy were evaluated. Cases were retrieved from a departmental shock wave lithotripsy database. Variables analyzed included BMI of the case, diameter of proximal ureter and renal pelvis, stone size and Hounsfield unit, ureteral wall thickness at the impacted stone site. Stone-free status on follow-up imaging at 3 months was considered a successful outcome. All patients had a single impacted proximal ureteral stone. While the mean age of the cases was 46 ± 13 years (range 26-79 years), mean stone size was 8.95 mm (5.3-15.1 mm). Following shock wave lithotripsy although 87 patients (78.4%) were completely stone-free at 3-month follow-up visit, 24 (21.6%) cases had residual fragments requiring further repeat procedures. Prediction of the final outcome of SWL in patients with impacted proximal ureteral stones is a challenging issue and our data did clearly indicate a highly significant relationship between ureteral wall thickness and the success rates of shock wave lithotripsy particularly in cases requiring additional procedures. Of all the evaluated stone- and patient-related factors, only ureteral wall thickness at the impacted stone site independently predicted shock wave lithotripsy success.

    Factor analysis (principal component analysis followed by varimax rotation) had shown that 3 common factors appear across 20 critical-band power fluctuations derived from spoken sentences of eight different languages [Ueda et al. (2010). Fechner Day 2010, Padua]. The present study investigated the contributions of such power-fluctuation factors to speech intelligibility. The method of factor analysis was modified to obtain factors suitable for resynthesizing speech sounds as 20-critical-band noise-vocoded speech. The resynthesized speech sounds were used for an intelligibility test. The modification of factor analysis ensured that the resynthesized speech sounds were not accompanied by a steady background noise caused by the data reduction procedure. Spoken sentences of British English, Japanese, and Mandarin Chinese were subjected to this modified analysis. Confirming the earlier analysis, indeed 3-4 factors were common to these languages. The number of power-fluctuation factors needed to make noise-vocoded speech intelligible was then examined. Critical-band power fluctuations of the Japanese spoken sentences were resynthesized from the obtained factors, resulting in noise-vocoded-speech stimuli, and the intelligibility of these speech stimuli was tested by 12 native Japanese speakers. Japanese mora (syllable-like phonological unit) identification performances were measured when the number of factors was 1-9. Statistically significant improvement in intelligibility was observed when the number of factors was increased stepwise up to 6. The 12 listeners identified 92.1% of the morae correctly on average in the 6-factor condition. The intelligibility improved sharply when the number of factors changed from 2 to 3. In this step, the cumulative contribution ratio of factors improved only by 10.6%, from 37.3 to 47.9%, but the average mora identification leaped from 6.9 to 69.2%. The results indicated that, if the number of factors is 3 or more, elementary linguistic

    This paper outlines specific tips for those applying to pulmonary and/or critical care medicine fellowship training in the United States using the PAIR-Match steps: preparation, application, interview, ranking, and match. Preparation for fellowship begins long before the application process with an assessment of one's long-term goals (to the extent that these are known). The cornerstone of the application is the curriculum vitae, which should highlight applicants' pulmonary and critical care-related experiences and scholarly work. Applicants should obtain letters of recommendation from faculty members who know them well and can write a letter that speaks to their strengths in clinical, scholarly, or leadership areas. The personal statement is an opportunity to share experiences not otherwise shared in the application and is an opportunity to explain any breaks in training or performance lapses. When selecting programs to which they will apply, applicants should pay close attention to the areas of education and curriculum, clinical experience, scholarly opportunity, and personal factors. Preparing for interviews should include a review of the program at which one is interviewing and development of relevant questions regarding details of the program. The interview day is the applicant's opportunity to see the "personality" of the program by meeting with the program director, faculty, and current fellows and to assess whether the program is a good fit for their goals. Applicants should only rank those programs they are willing to attend, in order of preference; they should be aware that the match process is binding.

    Objectives To test whether early life factors (education, height, father’s social position) and midlife social, behavioral and psychosocial factors were associated with entering older age without disease and good functioning. Design A longitudinal, British civil service-based cohort study. Participants were followed for 17 years to assess successful aging. This was defined as being free of major disease and in the top tertile of physical and cognitive functioning measured in 2002–4. Setting Twenty London-based Civil Service departments Participants Four thousand, one hundred and forty men and 1823 women, free of major disease at baseline in 1985–8 (mean age 44, range 35–55 years) Measurements Behavioral, biological and psychosocial risk factors, physical and cognitive functioning and disease outcomes Results 548 (12.8%) men and 246 (14.6%) women were successfully aging at follow up. This was strongly predicted by midlife socioeconomic position (age adjusted odds ratio for men highest vs. lowest 7.06, 95% CI 3.4, 14.6). Height, education (men), not smoking, diet, exercise, moderate alcohol (women) and work support (men) were related to a favorable older life after adjustment for age and socioeconomic position. Conclusion Interventions to promote adult healthy behavior may attenuate harmful effects of less modifiable risk factors and reduce social inequalities. PMID:18482302

    Ratings of the perceived relative importance of psychological and physical factors for successful athletic performance were obtained from 29 men and 53 women in sports of track, swimming, soccer, volleyball, basketball, gymnastics, baseball or softball, tennis, diving, and golf, by level of competition (high school, college, and professional), and sex of athlete. The over-all rating of the relative importance of psychological factors was 39%. Significant differences in the ratings of the relative importance of psychological factors were found for sport, level, sex, sport x level, and level x sex. Ratings of the relative importance of psychological factors for successful performance in various sports increased in the order listed above. The significant effect for level and interaction of sport x level were accounted for primarily by the higher ratings given to professional golf. The significant effect of sex and the interaction of sex x level were attributable to higher ratings of the importance of psychological variables for high school women athletes as compared to high school men athletes.

  19. Factors that promote success in women enrolled in STEM disciplines in rural North Carolina community colleges

    NASA Astrophysics Data System (ADS)

    Kincaid, Shannon D.

    Women have historically been underrepresented in the fields of science, technology, engineering, and math (STEM fields). The underrepresentation of women in STEM may be attributable to a variety of factors. These may include different choices men and women typically make in response to incentives in STEM education. For example, STEM career paths may be less accommodating to people who are less resilient. Another factor may be that there are relatively few female STEM role models. Perhaps strong gender stereotypes discourage women from pursuing STEM education and STEM jobs. The factors that contribute to success and the barriers that impeded success must be identified before any steps can be taken to improve the educational outcomes for women in STEM disciplines. Consequently, relatively little is known about the role of resilience in academically successful adult women in rural community colleges enrolled in STEM disciplines and the mechanisms that underlie the performance deficits that occur as a result of stereotype threat effect. This mixed method study addressed those knowledge gaps by determining: (1) if high resilience is positively correlated to high grade point average for women enrolled in STEM disciplines in rural community colleges in North Carolina, and (2) if stereotype threat effect is a risk factor for these women. Quantitative data were collected by using "The Resilience Scale" (Wagnild & Young, 1987) and through examination of grade point average of students from Datatel data management software. Qualitative data were collected through semi-structured focus group interviews. Findings from this study indicate high resilience is positively correlated to high grade point average for women enrolled in STEM disciplines in rural community colleges in North Carolina, and stereotype threat effect was a risk factor for low-scoring women (i.e. those women who reported resilience scores less than 121 and grade point averages lower than 2.70) and was not a

    At the heart of research is the scientific process, which includes identifying a knowledge gap, execution of experiments, and finally, presentation of scientific data. Identifying a systematic way to undertake research is important; however, equally important are intangible factors, including strategy, innovation and leadership, in determining the outcome of any research project. These intangible factors, although often unspoken, are the essence of success in research. Strategy determines the direction of research and the ability to respond to acute changes in the field to ensure a competitive advantage. Innovation involves generating novel ideas, and at the heart of innovation is the ability to create a positive work environment. Leadership is the ability to exercise influence so as to create change; empowerment and the ability to create leaders at every level are central to effective leadership. Collectively, defining and implementing aspects of these intangible factors will strengthen any research endeavor.

    Continuing medical education's transition from an emphasis on dissemination to changing clinical practice has made it increasingly necessary for CME providers to develop effective interorganizational collaborations. Although interorganizational collaboration has become commonplace in most sectors of government, business, and academia, our review of the literature and experience as practitioners and researchers suggest that the practice is less widespread in the CME field. The absence of a rich scholarly literature on establishing and maintaining interorganizational collaborations to provide continuing education to health professionals means there is little information about how guidelines and principles for effective collaboration developed in other fields might apply to continuing professional development in health care and few models of successful collaboration. The purpose of this article is to address this gap by describing a successful interorganizational CME collaboration-Cease Smoking Today (CS2day)-and summarizing what was learned from the experience, extending our knowledge by exploring and illustrating points of connection between our experience and the existing literature on successful interorganizational collaboration. In this article, we describe the collaboration and the clinical need it was organized to address, and review the evidence that led us to conclude the collaboration was successful. We then discuss, in the context of the literature on effective interorganizational collaboration, several factors we believe were major contributors to success. The CS2day collaboration provides an example of how guidelines for collaboration developed in various contexts apply to continuing medical education and a case example providing insight into the pathways that lead to a collaboration's success.

    Microstructural defects are the primary determining factors for the values of critical current densities in superconductors. A review is made to assess, (1) what would be the maximum achievable critical-current density in the oxide superconductors if nearly ideal pinning sites were introduced and (2) what types of pinning defects are currently introduced in these superconductors and how effective are these in pinning the vortices Only the case where the applied field is parallel to the c-axis is considered here.

    Biological soil crusts play important ecological functions in arid and semi-arid regions, while different crust successional patterns appeared in different regions. Therefore in this study, the environmental conditions between Shapotou (with cyanobacterial, lichen and moss crusts) and Dalate Banner (with only cyanobacterial and moss crusts) regions of China were compared to investigate why lichen crusts only appeared in Shapotou; at the same time, artificial moss inoculation was conducted to find out the environmental factors promoting crust succession to moss stage. The results showed lichen crusts always developed from cyanobacterial crusts, which provide not only the stable soil surface, but also the biomass basis for lichen formation; furthermore, addition of crust physicochemical characteristics (primarily silt content) play a facilitating effect on lichen emergence (R(2)=0.53). The inoculation experiment demonstrated early crust soil surface and enough water holding content (>4%) provided the essential guarantee for moss germination. Our results show that there is heterogeneity in crust succession in different regions, which may be mainly affected by the ambient soil microenvironments. It is concluded that a positive feedback mechanism is expected between crust succession and ambient soil microenvironments; while a negative feedback mechanism forms between crust succession and free living cyanobacteria and algae.

    In spite of sustained efforts tertiary institutions implement to try and improve student academic performance, the number of students succeeding in first-year mathematics courses remains disturbingly low. For most students, the gap between their mathematical capability and the competencies they are expected and need to develop to function effectively in these courses persists even after course instruction. In this study, an instrument for identifying and examining factors affecting student performance and success in a first-year Mathematics university course was developed and administered to 86 students. The overall Cronbach's Alpha coefficient for the questionnaire was found to be 0.916. Having identified variables from prior research known to affect student performance, factor analysis was used to identify variables exhibiting the greatest impact on student performance. The variables included prior academic knowledge, workload, student approaches to learning, assessment, student support teaching quality, methods and resources. From the analysis, students' perceptions of their workload emerged as the factor having the greatest impact on student's performance, followed by the matriculation examination score. The findings are discussed and strategies that can be used to improve teaching and contribute to student success in a first-year mathematics course in a South African context are presented.

    2015-01-01

    Introduction: In developing countries, chronic otitis media (COM) and cholesteatoma are relatively prevalent. Within the field of otology, COM surgery remains one of the most common surgical treatments. Most recent studies evaluating the potential prognostic factors in COM surgery have addressed graft success rate and types of middle ear and mastoid pathology. There has been much controversy about this issue until the present time. This study evaluated the effect of cholesteatoma on the GSR in COM surgery. Materials and Methods: The present retrospective, case-controlled study investigated 422 ears undergoing COM surgery. The minimum and maximum postoperative follow-up periods were 6 and 48 months, respectively. The study group consisted of patients with cholesteatomatous COM, while the control group included patients with non-cholesteatomatous COM, who had undergone ear surgery. Postoperative graft success rate and audiological test results were recorded and the effect of cholesteatoma on graft success rate was investigated. Results: The overall GSR was 92.4%. In the study group (COM with cholesteatoma),the postoperative GSR, mean speech reception threshold improvement, and mean air-bone gap gain were 95.3%, 2.1 dB, and 3.2 dB, respectively. In the control group (COM without cholesteatoma), however, these measurements were 90.9%, 9.4 dB, and 9.1 dB, respectively. The difference between the two groups was not statistically significant. Conclusion: The study results suggest that cholesteatoma is not a significant prognostic factor in graft success rate. PMID:26788485

    2012-06-01

    A summer bridge program for incoming engineering and computer science freshmen has been used at the University of Wisconsin-Milwaukee from 2007 to 2010. The primary purpose of this program has been to improve the mathematics course placement for incoming students who initially place into a course below Calculus I on the math placement examination. The students retake the university's math placement examination after completing the bridge program to determine if they then place into a higher-level mathematics course. If the students improve their math placement, the program is considered successful for that student. The math portion of the bridge program is designed around using the ALEKS software package for targeted, self-guided learning. In the 2007 and 2008 versions of the program, both an on-line version and an on-campus version with additional instruction were offered. In 2009 and 2010, the program was exclusively in an on-campus format, and also featured a required residential component and additional engineering activities for the students. From the results of these four programs, we are able to evaluate the success of the program in its different formats. In addition, data has been collected and analysed regarding the impact of other factors on the program's success. The factors include student preparation before the beginning of the program (as measured by math ACT scores) and the amount of time the student spent working on the material during the program. Better math preparation and the amount of time spent on the program were found to be good indicators of success. Furthermore, the on-campus version of the program is more effective than the on-line version.

  9. Successful Use of Four Factor-Prothrombin Complex Concentrate for Congenital Factor X Deficiency in the Setting of Neurosurgery.

    2016-08-01

    Congenital factor X deficiency is an extremely rare coagulation disorder that can place patients at risk for spontaneous hemorrhage or excessive bleeding in the setting of trauma or invasive procedures. Given the rarity of this disorder, there is little published guidance on how best to prevent or treat bleeding. Herein, we report a case of a 56-year-old white man with congenital factor X deficiency who was scheduled for major neurosurgery and who was treated perioperatively with 4-factor prothrombin complex concentrate (4F-PCC). Doses of 4F-PCC at 15 U per kg, administered immediately preoperatively and once at 24 hours postoperatively, allowed for successful completion of an anterior cervical discectomy and fusion without excessive bleeding. Moreover, no thromboembolic complications were observed. As such, given the wide availability of 4F-PCC, it may be considered as a first-line therapy and an alternative to fresh frozen plasma for factor X deficiencies, particularly in high-risk operative cases.

    Since the 1950s, clinicians have relied on various formulations of Ca(OH)2 to stimulate dentin bridge formation. Various studies (Kozlov and Massler, 1966; Massler, 1967; Brännström, 1978; Cox et al., 1987; Snuggs et al., 1993) have demonstrated that pulp healing and dentin bridging can occur against a pH spectrum of materials. Recent studies (Akimoto et al., 1998; Cox et al., 1998, 1999; Tarim et al., 1998; Kitasako et al., 1999; Hafez et al., 2000) have reported successful pulp healing and dentin bridging using adhesives for direct capping of exposed pulps. However, others (Costa et al., 1997; Stanley and Pameijer, 1997; Pameijer, 1998; Hebling et al., 1999; Carvalho et al., 2000) have reported unsatisfactory results when exposures were direct-capped with adhesives. Biological and technical factors, or a combination of both, might be postulated to explain these differences. Recent studies have demonstrated that biological success is dependent upon proper hemorrhage control at the exposure site. This review explores the differences and common factors influencing successful dentin bridging, focusing on data derived from animal studies conducted according to ISO usage guidelines for cavity preparation and material placement. In the past, there has been concern that etching of vital dentin leads to immediate pulp death due to low pH. Recent studies have reported that acidic cements cause breakdown of only the smear layer and fail to seal the restoration interface, leading to inflammation and necrosis. A properly hybridized dentinadhesive interface provides a "bacteriometic" seal to both dentin and pulp tissues. Recent ISO usage studies have shown a high incidence of dentin bridging with adhesives following proper hemorrhage control and removal of both operative debris and biofilm at the dentin-pulp interface by agents such as NaOCl. These are important technique-sensitivity factors to be considered for pulp healing and dentin bridge formation.

    Factor VII (FVII) deficiency is an infrequent hereditary bleeding disorder that can make excessive bleeding in surgical interventions, such as a postpartum hemorrhage in a cesarean section. Although a recombinant form of activated FVII has been applied for bleeding control in FVII-deficient patients, its applications in the field of obstetrics are still limited, especially in Korea. Replacement of blood products is still preferred as first-line therapy, with antifibrinolytic agents used as adjunctive therapy. We report herein the case of a successful cesarean section in an 18-year-old woman with FVII deficiency. PMID:25105106

    This study investigates how Latina/Latino youth resist, conform to, and persist in schooling, and explores their preparation for an education in science, technology, engineering and math (STEM) fields. Using Latino Critical Race Theory as a framework, evidence of the "sticky mess" of racial inequalities (Espinoza and Harris in Calif Law Rev 10:499-559, 1997) and the concept of community cultural wealth (Yosso in Race Ethn Educ 8:69-91, 2005) will be used to understand how Latina/o students successfully persist in college. Quantitative and qualitative findings collected at two public universities in 2007-2012 show that Latina/o parents play a significant role in influencing their children's decision to attend college; family, friend and community support and hard work have also been instrumental in college success. This is evident through parents' encouragement to persist, expectations to do well and students serving as role models for siblings and peers. As policy makers in the educational arena emphasize STEM fields, there is a significant opportunity for Latino students to make valuable contributions.

    Survivorship of larvae of the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae), was measured after they were raised on one of six diets. The effects of container shape (wide and shallow vs. narrow and deep), soil depth (0, 0.5, 1.0, 2.0, 4.0, and 8.0 cm), and temperature (28°, 32°, or 35° C) on pupation success was measured. Diet influenced larval survivorship, but did not have a strong effect on larval weight. The larvae fed only bee brood survived the shortest period of time. The larvae that were denied pupation substrate, fed only honey and pollen, and no other food or water after 20 days, had a median survivorship of 47.6 days, with a maximum of 61 days, while those fed only brood had a median survivorship of 18.2 days. Pupation substrate was essential for successful pupation, and the depth of the substrate, not its top surface area, was the crucial factor. Pupation success in narrow and deep containers was 95.6% on average, but only 12.5% in wide and shallow containers, using the same soil volume. In narrow and deep containers, most or all larvae kept in 4-8 cm of soil pupated at all temperatures, few larvae kept at 2 cm soil depth pupated, one out of 240 kept at 1.0 cm pupated, and no larvae kept at soil depths of 0 or 0.5 cm pupated.

    Immediate loading of dental implants has become a widely reported practice with success rates ranging from 70.8% to 100%. Although most studies have considered implant survival to be the only measure of success, a better definition includes the long-term stability of the hard and soft tissues around the implant(s) and other adjacent structures, as well as the long-term stability of all the restorative components. The parameters identified in 1981 by Albrektsson and colleagues as influencing the establishment and maintenance of osseointegration have been reconsidered in relation to immediate loading to improve the chances of achieving such success. Two of the six parameters (status of the bone/implant site and implant loading conditions) have preoperative diagnostic implications, whereas three (implant design, surgical technique, and implant finish) may compensate for less-than-ideal site and loading conditions. Factors affecting the outcome of immediate loading are reviewed to assist clinicians attempting to assess its risks and benefits. PMID:20455906

    Recent studies have examined the effects of livestock grazing, agriculture, and human habitation on nest predation and brood parasitism in riparian areas in the western United States. However, we know little about factors influencing nest success in riparian areas lacking such anthropogenic influences, in part because the influences are so pervasive. We studied riparian bird communities in a 115 000 ha wildlife refuge where livestock grazing was discontinued > 10 years ago, and which has little nearby agriculture or human habitation. We monitored nests on 24 aspen (Populus tremuloides) and 10 willow (Salix spp.) plots. Brood parasitism rates were substantially lower than at other western sites and did not differ between aspen and willow habitats. Nest success in aspen was relatively high compared to that reported for other western sites and higher than in willow. Predators may have been able to find nests more efficiently in willow than in aspen because territory densities were higher in willow (40 versus 30 pairs per ha, respectively), because willow had less structural heterogeneity, or both. We did not find strong evidence that nest success was influenced by aspen patch size or distance to riparian edge, indicating that even small aspen patches provide valuable nesting habitat. Weather was an important cause of nest failure, particularly at higher elevations during late-spring snowstorms. Our results indicate that riparian areas without major anthropogenic impacts, especially aspen stands, constitute high-quality breeding habitat and warrant conservation focus. ??

  11. Predicting College Success: The Relative Contributions of Five Social/Personality Factors, Five Cognitive/Learning Factors, and SAT Scores

    PubMed Central

    Hannon, Brenda

    2014-01-01

    To-date, studies have examined simultaneously the relative predictive powers of two or three factors on GPA. The present study examines the relative powers of five social/personality factors, five cognitive/learning factors, and SAT scores to predict freshmen and non-freshmen (sophomores, juniors, seniors) academic success (i.e., GPA). The results revealed many significant predictors of GPA for both freshmen and non-freshmen. However, subsequent regressions showed that only academic self-efficacy, epistemic belief of learning, and high-knowledge integration explained unique variance in GPA (19%-freshmen, 23.2%-non-freshmen). Further for freshmen, SAT scores explained an additional unique 10.6% variance after the influences attributed to these three predictors was removed whereas for non-freshmen, SAT scores failed to explain any additional variance. These results highlight the unique and important contributions of academic self-efficacy, epistemic belief of learning and high-knowledge integration to GPA beyond other previously-identified predictors.

    Oligotrophic fish communities of the Great Lakes have undergone successive disruptions since the mid-1800s. Major contributing factors have been intensive selective fisheries, extreme modification of the drainage, invasion of marine species, and progressive physical–chemical changes of the lake environments. Lake Ontario was the first to be affected as its basin was settled and industrialized earliest, and it was the first to be connected by canals to the mid-Atlantic where the alewife (Alosa pseudoharengus) and sea lamprey (Petromyzon marinus) which ultimately became established in the Great Lakes were abundant. Oligotrophic fish communities were successively disrupted in Lakes Erie, Huron, Michigan, and Superior as the affects of population growth, industrialization, and marine invaders spread upward in the Laurentian drainage.The degree and sequence of response of families offish and species within families differed for each factor, but the sequence of change among families and species has been the same in response to each factor as it affected various lakes at different times. The ultimate result of the disruption of fish communities has been a reduction of productivity of oligotrophic species that ranges from extreme in Lake Ontario to moderate in Lake Superior, and which has reached a state of instability and rapid change in the upper three Great Lakes by the rnid-1900s similar to the situation in Lake Ontario in the mid-1800s. Since oligotrophic species (primarily salmonines, coregonines, and deepwater cottids) are the only kinds of fish that fully occupied the entire volume of the deepwater Great Lakes (Ontario, Huron, Michigan, and Superior), the fish biomass of these lakes has been reduced as various species declined or disappeared. In Lake Erie, which is shallow, and in the shallow bays of the deep lakes, oligotrophic species were replaced by mesotrophic species, primarily percids, which have successively increased and declined. All oligotrophic

    Measurements of atmospheric mercury (Hg) are being increasingly incorporated into monitoring networks worldwide. These data are expected to support and inform regulatory decision making aimed at protecting human and wildlife health. Here we critically review current efforts to measure Hg concentrations in the atmosphere and interpret these data with Hg models. There are three operationally defined forms of atmospheric Hg: Gaseous Elemental (GEM), Gaseous Oxidized (GOM), and Particulate Bound (PBM). While there is relative confidence in GEM measurements, GOM and PBM are less well understood. Field and laboratory investigations suggest the methods to measure GOM and PBM are impacted by analytical interferences that vary with environmental setting (e.g., ozone, relative humidity) and GOM concentrations can be biased low by a factor of 1.6-12 times depending on the chemical compound. Importantly, efforts to understand the fundamental limitations of atmospheric Hg measurement methods have provided clear evidence that the composition of GOM (e.g., HgBr2, HgCl2, HgBrOH) varies across space and time. This has significant implications for refining existing measurement methods and developing new ones, model/measurement comparisons, model development, and assessing trends. In addition, unclear features of previously published data may now be re-examined and possibly explained, which we present as a case study. Lastly, we outline recommendations for needed research directions as the Hg field moves forward. Priorities include GOM and PBM calibration systems, identification of GOM compounds in ambient air, and identification of redox mechanisms and associated rate coefficients. Determination of a quantitative correction factor for biased GOM and PBM data is also needed to facilitate model-measurement comparisons.

  14. Statistical iterative reconstruction using fast optimization transfer algorithm with successively increasing factor in Digital Breast Tomosynthesis

    Statistical iterative reconstruction exhibits particularly promising since it provides the flexibility of accurate physical noise modeling and geometric system description in transmission tomography system. However, to solve the objective function is computationally intensive compared to analytical reconstruction methods due to multiple iterations needed for convergence and each iteration involving forward/back-projections by using a complex geometric system model. Optimization transfer (OT) is a general algorithm converting a high dimensional optimization to a parallel 1-D update. OT-based algorithm provides a monotonic convergence and a parallel computing framework but slower convergence rate especially around the global optimal. Based on an indirect estimation on the spectrum of the OT convergence rate matrix, we proposed a successively increasing factor- scaled optimization transfer (OT) algorithm to seek an optimal step size for a faster rate. Compared to a representative OT based method such as separable parabolic surrogate with pre-computed curvature (PC-SPS), our algorithm provides comparable image quality (IQ) with fewer iterations. Each iteration retains a similar computational cost to PC-SPS. The initial experiment with a simulated Digital Breast Tomosynthesis (DBT) system shows that a total 40% computing time is saved by the proposed algorithm. In general, the successively increasing factor-scaled OT exhibits a tremendous potential to be a iterative method with a parallel computation, a monotonic and global convergence with fast rate.

    This exploratory study has two aims: (1) to find out if and how social media (SM) applications are used by hospitals in Spain and (2) to assess hospital managers' perception of these applications in terms of their evaluation of them, reasons for use, success factors, and difficulties encountered during their implementation. A cross-sectional survey has been carried out using Spanish hospitals as the unit of analysis. Geographical differences in the use of SM were found. Social networks are used most often by larger hospitals (30% by medium-size, 28% by large-size). They are also more frequently used by public hospitals (19%, p<0.01) than by private ones. Respondents with a negative perception of SM felt that there is a chance they may be abused by healthcare professionals, whereas those with a positive perception believed that they can be used to improve communication both within and outside the hospital. Reasons for the use of SM include the idea of maximizing exposure of the hospital. The results show that Spanish hospitals are only just beginning to use SM applications and that hospital type can influence their use. The perceptions, reasons for use, success factors, and difficulties encountered during the implementation of SM mean that it is very important for healthcare professionals to use SM correctly and adequately.

    Stelzmann, Ernst; Kreiner, Christian; Spork, Gunther; Messnarz, Richard; Koenig, Frank

    Agile software development methods are widely accepted and valued in software-dominated industries. In more complex setups like multidisciplinary system development the adoption of an agile development paradigm is much less straightforward. Bigger teams, longer development cycles, process and product standard compliance and products lacking flexibility make an agile behaviour more difficult to achieve. Focusing on the fundamental underlying problem of dealing with ever ongoing change, this paper presents an agile Systems Engineering approach as a potential solution. Therefore a generic Systems Engineering action model was upgraded respecting agile principles and adapted according to practical needs discovered in an empirical study. This study was conducted among the partners of the S2QI agile workgroup made up from experts of automotive, logistics and electronics industries. Additionally to an agile Systems Engineering action model, a list of 15 practical success factors that should be considered when using an agile Systems Engineering approach is one of the main outcomes of this survey. It was also found that an agile behaviour in Systems Engineering could be supported in many different areas within companies. These areas are listed and it is also shown how the agile action model and the agile success factors are related to them.

  1. Human Factors Engineering Requirements for the International Space Station - Successes and Challenges

    2003-01-01

    Advanced technology coupled with the desire to explore space has resulted in increasingly longer human space missions. Indeed, any exploration mission outside of Earth's neighborhood, in other words, beyond the moon, will necessarily be several months or even years. The International Space Station (ISS) serves as an important advancement toward executing a successful human space mission that is longer than a standard trip around the world or to the moon. The ISS, which is a permanently occupied microgravity research facility orbiting the earth, will support missions four to six months in duration. In planning for the ISS, the NASA developed an agency-wide set of human factors standards for the first time in a space exploration program. The Man-Systems Integration Standard (MSIS), NASA-STD-3000, a multi-volume set of guidelines for human-centered design in microgravity, was developed with the cooperation of human factors experts from various NASA centers, industry, academia, and other government agencies. The ISS program formed a human factors team analogous to any major engineering subsystem. This team develops and maintains the human factors requirements regarding end-to-end architecture design and performance, hardware and software design requirements, and test and verification requirements. It is also responsible for providing program integration across all of the larger scale elements, smaller scale hardware, and international partners.

    study area and averaged [unweighted] over all study areas) was 17% in 1982, 15% in 1983, 7% in 1984, and 14% in 1985.We estimated that predators destroyed 72% of mallard, gadwall, blue-winged teal, and northern shoveler nests and 65% of northern pintail nests. In prairie, average nest success decreased about 4 percentage points for every 10 percentage points increase in Cropland, suggesting that under conditions of 1982-85, local populations of these species probably were not stable when Cropland exceeded about 56% of available habitat. We found recent remains of 573 dead ducks during 1983-85; most were females (Anas spp.) apparently killed by predators. In some years, mallards and northern pintails were more numerous among dead ducks than we expected. More females than males were found dead among mallards and northern shovelers, suggesting higher vulnerability of females. Of factors we examined, nest-success rate appeared to be the most influential factor in determining mallard production. Nest success varied both geographically and annually.

  3. Risk factors for invasive fungal disease in critically ill adult patients: a systematic review

    2011-01-01

    Introduction Over 5,000 cases of invasive Candida species infections occur in the United Kingdom each year, and around 40% of these cases occur in critical care units. Invasive fungal disease (IFD) in critically ill patients is associated with increased morbidity and mortality at a cost to both the individual and the National Health Service. In this paper, we report the results of a systematic review performed to identify and summarise the important risk factors derived from published multivariable analyses, risk prediction models and clinical decision rules for IFD in critically ill adult patients to inform the primary data collection for the Fungal Infection Risk Evaluation Study. Methods An internet search was performed to identify articles which investigated risk factors, risk prediction models or clinical decisions rules for IFD in critically ill adult patients. Eligible articles were identified in a staged process and were assessed by two investigators independently. The methodological quality of the reporting of the eligible articles was assessed using a set of questions addressing both general and statistical methodologies. Results Thirteen articles met the inclusion criteria, of which eight articles examined risk factors, four developed a risk prediction model or clinical decision rule and one evaluated a clinical decision rule. Studies varied in terms of objectives, risk factors, definitions and outcomes. The following risk factors were found in multiple studies to be significantly associated with IFD: surgery, total parenteral nutrition, fungal colonisation, renal replacement therapy, infection and/or sepsis, mechanical ventilation, diabetes, and Acute Physiology and Chronic Health Evaluation II (APACHE II) or APACHE III score. Several other risk factors were also found to be statistically significant in single studies only. Risk factor selection process and modelling strategy also varied across studies, and sample sizes were inadequate for obtaining

    In recent years there have been immense pressures to enact changes on the air traffic control organizations of most states. In addition, many of these states are or have been subject to great political, sociological and economic changes. Consequently, any new schemes must be considered within the context of national or even international changes. Europe has its own special problems, and many of these are particularly pertinent when considering human factors certification programs. Although these problems must also be considered in the wider context of change, it is usually very difficult to identify which forces are pressing in support of human factors aspects and which forces are resisting change. There are a large number of aspects which must be taken into account if human factors certification programs are to be successfully implemented. Certification programs would be new ventures, and like many new ventures it will be essential to ensure that managers have the skills, commitment and experience to manage the programs effectively. However, they must always be aware of the content and the degree of certainty to which the human factors principles can be applied - as Debons and Horne have carefully described. It will be essential to avoid the well known pitfalls which occur in the implementation of performance appraisal schemes. While most appraisal schemes are usually extremely well thought out, they often do not produce good results because they are not implemented properly and staff therefore do not have faith in them. If the manager does not have the commitment and interest in his/her staff as human beings, then the schemes will not be effective. Thus, one aspect of considering human factors certification schemes is within the context of a managed organization. This paper outlines some of the management factors which need to be considered for the air traffic control services. Many of the points received attention during the plenary sessions while others were

  5. Exploration of Factors Affecting Success of Undergraduate Engineering Majors at a Historically Black University

    NASA Astrophysics Data System (ADS)

    Igbinoba, Egheosa P.

    Blacks are underrepresented amongst persons who earn college degrees in the United States and Black males attend and complete college at a lower rate than Black females (Toldson, Fry Brown, & Sutton, 2009). According to Toldson et al. (2009), this quandary may be attributed to Black males' apathy toward education in general, waning support and ideological challenges toward Pell Grants and affirmative action, cultural incompetency on the part of the 90% White, ethnic makeup of the U.S. teaching force, and the relatively high numbers of Black males who are held back in school. In spite of the dismal statistics regarding Black male academic achievement and matriculation, there are those Black males who do participate in postsecondary education. While many studies have highlighted reasons that Black males do not achieve success in attending and persisting through college, few have adopted the anti-deficit research framework suggested by Harper (2010), identifying reasons Black males do persist in higher education. Although science, technology, engineering, and mathematics careers are identified as those most imperative to the economic competitiveness of the United States, few studies have concentrated solely on engineering majors and fewer, if any, solely on Black male engineering majors at an historically Black college and university. The aim of this study was to address an apparent gap in the literature and invoke theories for recruitment, retention, and success of Black males in engineering degree programs by employing an anti-deficit achievement framework for research of students of color in science, technology, engineering, and mathematics. Data garnered from the study included insight into participants' definitions of success, precollege experiences, factors contributing to the persistence during undergraduate study, and perceptions of attending a historically Black college and university versus a primarily White institution.

  6. Success Factors in Human Space Programs - Why Did Apollo Succeed Better Than Later Programs?

    The Apollo Program reached the moon, but the Constellation Program (CxP) that planned to return to the moon and go on to Mars was cancelled. Apollo is NASA's greatest achievement but its success is poorly understood. The usual explanation is that President Kennedy announced we were going to the moon, the scientific community and the public strongly supported it, and Congress provided the necessary funding. This is partially incorrect and does not actually explain Apollo's success. The scientific community and the public did not support Apollo. Like Apollo, Constellation was announced by a president and funded by Congress, with elements that continued on even after it was cancelled. Two other factors account for Apollo's success. Initially, the surprise event of Uri Gagarin's first human space flight created political distress and a strong desire for the government to dramatically demonstrate American space capability. Options were considered and Apollo was found to be most effective and technically feasible. Political necessity overrode both the lack of popular and scientific support and the extremely high cost and risk. Other NASA human space programs were either canceled, such as the Space Exploration Initiative (SEI), repeatedly threatened with cancellation, such as International Space Station (ISS), or terminated while still operational, such as the space shuttle and even Apollo itself. Large crash programs such as Apollo are initiated and continued if and only if urgent political necessity produces the necessary political will. They succeed if and only if they are technically feasible within the provided resources. Future human space missions will probably require gradual step-by-step development in a more normal environment.

    Polyarteritis nodosa is a rare systemic necrotizing vasculitis of small- and medium-sized arteries that affects patients of all ages. Its incidence ranges from 2 to 9 per million people. The 5-year survival rate is 13% in untreated patients and 77.6% with modern therapy. Standard treatment includes corticosteroids and cyclophosphamide. Despite aggressive medical management, 22.4% of patients die within 5 years, and of the survivors, medication-induced morbidity is frequent. There is great need for better treatment modalities in terms of safety and efficacy. We report the case of a 5-year-old boy with polyarteritis nodosa refractory to all known standard treatments. After 9 years of persistently active disease, at the age of 14, he was successfully managed with the tumor necrosis factor alpha antagonist, etanercept.

    This study investigated to what extent the implementation of a Google Earth (GE)-based earth science curriculum increased students' understanding of volcanoes, earthquakes, plate tectonics, scientific reasoning abilities, and science identity. Nine science classrooms participated in the study. In eight of the classrooms, pre- and post-assessments of earth science content, scientific reasoning, and science identity were completed. In one classroom, a staggered implementation of the curriculum was completed to control for student and teacher variables. In all nine classrooms, implementation of the GE curriculum advanced students' science identity, earth science understanding, and science reasoning, but the curriculum was most transformative in terms of scientific reasoning. Two factors were identified related to student success. Students with strong science identities and high reading proficiencies demonstrated greater science learning outcomes. Math proficiency and gender did not affect learning outcomes.

    To assess factors influencing the success of whole genome sequencing for mainstream clinical diagnosis, we sequenced 217 individuals from 156 independent cases across a broad spectrum of disorders in whom prior screening had identified no pathogenic variants. We quantified the number of candidate variants identified using different strategies for variant calling, filtering, annotation and prioritisation. We found that jointly calling variants across samples, filtering against both local and external databases, deploying multiple annotation tools and using familial transmission above biological plausibility contributed to accuracy. Overall, we identified disease causing variants in 21% of cases, rising to 34% (23/68) for Mendelian disorders and 57% (8/14) in trios. We also discovered 32 potentially clinically actionable variants in 18 genes unrelated to the referral disorder, though only four were ultimately considered reportable. Our results demonstrate the value of genome sequencing for routine clinical diagnosis, but also highlight many outstanding challenges. PMID:25985138

    This study reports the retrospective radiographic outcome of a series of 63 consecutive total knee arthroplasties using an uncemented hydroxyapatite-coated Duracon cruciate-retaining tibial baseplate (Stryker Howmedica Osteonics Corp, Mahwah, NJ). Sixty-three knees were assessed at a mean follow-up of 65 months. The knees were primarily diagnosed with osteoarthritis with a mean age of 61 years. Radiographic analysis showed 6 knees with tibial baseplate radiolucencies, with all of these resolving or improving over the course of the study. All tibial baseplates were implanted with the concomitant use of autologous bone slurry. There were no reoperations for aseptic loosening, fracture, or patellofemoral problems. This intermediate study demonstrates excellent radiographic outcomes for uncemented hydroxyapatite-coated Duracon cruciate-retaining tibial baseplates and evaluates other factors felt to be important in the success of a cementless implant.

    Mexican American youth are at greater risk of school failure than their peers. To identify factors that may contribute to academic success in this population, this study examined the prospective relationships from 5th grade to 7th grade of family (i.e., human capital [a parent with at least a high school education], residential stability, academically and occupationally positive family role models, and family structure) and individual characteristics (i.e., externalizing symptoms, bilingualism, gender, and immigrant status) to the academic performance of 749 Mexican American early adolescents (average age = 10.4 years and 48.7% were girls in 5th grade) from economically and culturally diverse families as these youth made the transition to junior high school. Results indicated that while controlling for prior academic performance, human capital and positive family role models assessed when adolescents were in 5th grade positively related to academic performance in 7th grade. Further, being a girl also was related to greater 7th grade academic success, whereas externalizing symptoms were negatively related to 7th grade academic performance. No other variables in the model were significantly and prospectively related to 7th grade academic performance. Implications for future research and interventions are discussed.

    The reproductive success of orchids is traditionally estimated by determining the fruit-set of individuals. Here, we investigated both the fruit and the seed production of three orchid species and the factors that may affect individual fruit-set, like pollination strategy, individual traits or the annual amount of precipitation. The species [Dactylorhiza sambucina (L.) Soó, Dactylorhiza majalis (Rchb.) P. F. Hunt & Summerhayes and Platanthera bifolia (L.) L. C. M. Richard] were studied in three consecutive years (2010-2012) in the Bükk Mountains, Hungary. All three species were proved to be non-autogamous by a bagging experiment. Data analyses showed significant differences between seed numbers but not between fruit-sets of species. There was no statistical difference in individual reproductive success between wet and dry years, however, the effect of the annual amount of precipitation is significant on the population level. Comparison of published fruit-set data revealed accordance with our results in P. bifolia, but not in D. sambucina and D. majalis. We assume that the surprisingly high fruit-set values of the two Dactylorhiza species may be due to the fact that the pollination crisis reported from Western European countries is not an actual problem in the Bükk Mountains, Hungary.

    Background It is unknown whether certain factors are associated with the success of in vitro fertilization (IVF) in women with inflammatory bowel disease (IBD). Aim This study assessed whether certain characteristics are associated with greater success of live birth following IVF. Methods In a cohort study of 8684 women with IBD seen at two tertiary care centers, we identified 121 women with IBD who underwent IVF. We assessed the effect of numerous factors on likelihood of achieving live birth after IVF. Results Seventy-one patients with ulcerative colitis (UC) and 49 patients with Crohn's disease (CD) were analyzed. Patients with UC who achieved a live birth were younger (p = 0.03), had a shorter duration of disease (p = 0.01), and were more likely to be in remission (p = 0.03) versus those who did not achieve live birth. Patients with CD who achieved live birth were younger (p < 0.001), had lower body mass index (BMI) (p = 0.02), and had lower cycle day 3 follicle-stimulating hormone levels (p = 0.02). There was no difference in likelihood of achieving live birth among patients in remission and those with mild or unknown disease status (p = 0.69), though most CD patients (79.5 %) were in remission. Prior surgery was not associated with live birth in patients with UC (p = 0.31) or CD (p = 0.62). Conclusions As in the general infertility population, younger patients and those with lower BMI were more likely to achieve live birth. History of surgery was not associated with live birth among IBD patients. This is important information for practitioners counseling IBD patients. PMID:26888767

    The goal of this study was to identify factors that influenced the ability to successfully rescue sperm post-mortem from rhinoceroses maintained in North American zoos. Factors considered included procedural technicalities, individual rhinoceros characteristics and timing. Gross testicular pathology was noted in 17.4% of males (4/23) but did not impact sperm recovery except in one case of azoospermia (4.3%). Of the males in which sperm recovery was attempted (n=21), 62% yielded quality samples considered adequate for cryopreservation (≥ 30% motility with ≥ 2.0 forward progressive status). A high percentage of males (70.6%; 12/17) from which reproductive tissue was removed an d cooled ≤ 4 h after death yielded quality sperm samples, whereas only 25% (1/4) of males from which tissue was removed>4h after death yielded quality samples. Quality samples were recovered 1-51 h post-mortem from rhinoceroses 8 to 36 years old. Neither type of illness (prolonged or acute), or method of death (euthanasia or natural) affected the ability to harvest quality samples (P > 0.05). The Indian rhinoceros yielded significantly more sperm on average (40 × 10(9)) than the African black rhinoceros (3.6 × 10(9); P < 0.01) and the African white rhinoceros (3.2 × 10(9); P < 0.05). Across all species and samples assessed (n = 11), mean post-thaw sperm motility (41%), was only 15% less than pre-freeze motility (56%) and only decreased to 22% during the 6h post-thaw assessment period. Rhinoceros sperm rescue post-mortem is relatively successful across a wide range of variables, especially when tissues are removed and cooled promptly after death, and should be considered standard practice among zoos.

    The practice of open cast mining, e.g. for lignite, results in major landscape disturbances and especially affects soils because relocation and subsequent mixing of naturally developed soil horizons leads to areas with extremely altered soil properties compared to the undisturbed conditions. Various reclamation measures are applied to recover the reconstructed landscape for different land use options. Major parts of the post mining landscapes are used for agriculture, agroforestry or silviculture, the remaining voids of the coal mines fill successively with groundwater after mine closure and are or will be used mainly for touristic and leisure purposes. Small proportions of the post mining areas are left for natural succession, or habitats for endangered flora and fauna are initiated. In reclamation research, many studies have focused on soil chemical and biological constraints of post mining substrates and investigated factors such as unsuitable pH, in many cases very low pH, (poor) nutrient contents and (poor) biological activity. But the initial and developing soil physical parameters and functions are also key factors for the success of reclamation practices. The soil water and gas balance influence strongly the suitability of a site for the intended future land use. The mechanical stability of the soil determines the rigidity of the pore system against deforming forces and thereby the persistence of soil functions, such as water and air permeability over time. The amendment of unfavourable (initial) soil physical properties is in most cases more complex and time-consuming than e.g. optimization of pH or fertilization with nutrients. Moreover, regarding the suitability of a site e.g. as a habitat for plants or microorganisms, poor physical pre-conditions can turn substrates with perfect nutrient contents and composition and pH into infertile locations of very low productivity. We show results of an on-going field study where the effects of different

    OBJECTIVE If we can identify critically ill children at high risk for central venous catheter-related thrombosis, then we could target them for pharmacologic thromboprophylaxis. We determined whether factor VIII activity or G value was associated with catheter-related thrombosis in critically ill children. DESIGN Prospective cohort study SETTING Two tertiary academic centers PATIENTS We enrolled children <18 years old who were admitted to the pediatric intensive care unit within 24 hours after insertion of a central venous catheter. We excluded children with a recently diagnosed thrombotic event or those anticipated to receive anticoagulation. Children with thrombosis diagnosed with surveillance ultrasonography on the day of enrollment were classified as having prevalent thrombosis. Those who developed catheter-related thrombosis thereafter were classified as having incident thrombosis. INTERVENTIONS None MEASUREMENTS AND MAIN RESULTS We enrolled 85 children in the study. Once enrolled, we measured factor VIII activity with one-stage clotting assay and determined G value with thromboelastography. Of those enrolled, 25 had incident and 12 had prevalent thromboses. The odds ratio for incident thrombosis per standard deviation increase in factor VIII activity was 1.98 (95% confidence interval: 1.10-3.55). The area under the receiver operating characteristic curve was 0.66 (95% confidence interval: 0.52-0.79). At factor VIII activity >100 IU/dL, which was the optimal threshold identified using Youden index, sensitivity and specificity were 92.0% and 41.3%, respectively. The association between factor VIII activity and incident thrombosis remained significant after adjusting for important clinical predictors of thrombosis (odds ratio: 1.93; 95% confidence interval: 1.10-3.39). G value was associated with prevalent but not with incident thrombosis. CONCLUSION Factor VIII activity may be used to stratify critically ill children based on their risk for catheter

    Borderline personality disorder (BPD) represents a significant therapeutic challenge. Critical factors in psychotherapeutic treatment of patients with BPD are noticeable and strictly related to the psychopathological dimensions of this disorder: affective and relational instability, behavioral impulsivity and precarious definition of identity. These features are emphasized by therapeutic intervention and become evident during the course of the treatment. Psychotherapeutic setting induces BPD patient to actualize the dysfunctional relational patterns that have been acquired during childhood. Specific critical factors concern the characteristics of the patient (risk of suicide, aggressive behaviors, chronic course of the disorder, disorganized attachment style), of the therapist (therapeutic skills, training, countertransference, risk of burnout) and of the setting of psychotherapy (patients selection, therapeutic alliance, need to set limits, duration and end of therapy). In Otto Kernberg's and Marsha Linehan's models of psychotherapy specific for DBP the authors identify substantially overlapping objectives and modalities of intervention. In particular, therapists should take care of patient safety, maintain boundaries of therapeutic setting and promote the development of psychotherapeutic process. The aim of this article is to analyze the main critical factors affecting psychotherapeutic process in patients with BPD. Objectives and priorities that therapist should consider to address these issues will be discussed. We will also try to make clear why interpersonal psychotherapy adapted to DBP can represent one of the therapeutic models that may be useful to manage and resolve these difficulties. PMID:27030345

    The emergence of real-time ultrasonic imaging for extracorporeal shockwave lithotripsy poses questions regarding the factors and techniques which facilitate stone imaging for clinicians with no previous practical experience in ultrasonography. The ability of these clinicians to assess when stone disintegration has been achieved also needs to be confirmed. A wide range of data was recorded from each of 2688 lithotripsy treatments performed over a 2-year period using the EDAP LT.01 ultrasound-imaged piezoelectric lithotriptor. An analysis of these data was performed using a comprehensive microcomputer-based statistics package. The mean time taken for stone imaging and positioning was reduced from 11.2 to 7.5 min over the 2-year period. Obese patients and those with renal pelvic stones were best imaged in a lateral position. Overall there was no difference in percentage stone disintegration or clearance between treatments in the supine or lateral positions, but a significant reduction in the clearance of small caliceal stones resulted when the lateral position was used. Factors associated with a significantly greater percentage of stone disintegration and clearance included pain experienced by the patient during fine adjustment of the processing head during treatment, acoustic focus attenuation and widening and acoustic shadow widening as detected by the urologist at the end of treatment. Among the factors not associated with significant alterations in the percentage of stone disintegration or clearance were the lithotriptor operator, the side or site of the calculus, obesity and shockwave frequency or power. This study confirmed the ability of urologists to develop expertise in ultrasonography for renal stone imaging and to interpret successfully the subtle signs of stone disintegration.

    The NASA Constellation Program's Ares I-X rocket launched successfully on October 28, 2009 collecting valuable data and providing risk reduction for the Ares I project. The Ares I-X mission was formulated and implemented in less than four years commencing with the Exploration Systems Architecture Study in 2005. The test configuration was founded upon assets and processes from other rocket programs including Space Shuttle, Atlas, and Peacekeeper. For example, the test vehicle's propulsion element was a Shuttle Solid Rocket Motor. The Ares I-X rocket comprised a motor assembly, mass and outer mold line simulators of the Ares I Upper Stage, Orion Spacecraft and Launch Abort System, a roll control system, avionics, and other miscellaneous components. The vehicle was 327 feet tall and weighed approximately 1,800,000 pounds. During flight the rocket reached a maximum speed of Mach 4.8 and an altitude of 150,000 feet. The vehicle demonstrated staging at 130,000 feet, tested parachutes for recovery of the motor, and utilized approximately 900 sensors for data collection. Developing a new launch system and preparing for a safe flight presented many challenges. Specific challenges included designing a system to withstand the environments, manufacturing large structures, and re-qualifying heritage hardware. These and other challenges, if not mitigated, may have resulted in test cancellation. Ares I-X succeeded because the mission was founded on carefully derived objectives, led by decisive and flexible management, implemented by an exceptionally talented and dedicated workforce, and supported by a thorough independent review team. Other major success factors include the use of proven heritage hardware, a robust System Integration Laboratory, multi-NASA center and contractor team, concurrent operations, efficient vehicle assembly, effective risk management, and decentralized element development with a centralized control board. Ares I-X was a technically complex test that

    Systematic investigations of complex pathological cascades during ischemic brain injury help to elucidate novel therapeutic targets against cerebral ischemia. Although some transcription factors (TFs) involved in cerebral ischemia, systematic surveys of their changes during ischemic brain injury have not been reported. Moreover, some multi-target agents effectively protected against ischemic stroke, but their mechanisms, especially the targets of TFs, are still unclear. Therefore, a comprehensive approach by integrating network pharmacology strategy and a new concatenated tandem array of consensus transcription factor response elements method to systematically investigate the target TFs critical in the protection against cerebral ischemia by a medication was first reported, and then applied to a multi-target drug, Danhong injection (DHI). High-throughput nature and depth of coverage, as well as high quantitative accuracy of the developed approach, make it more suitable for analyzing such multi-target agents. Results indicated that pre-B-cell leukemia transcription factor 1 and cyclic AMP-dependent transcription factor 1, along with six other TFs, are putative target TFs for DHI-mediated protection against cerebral ischemia. This study provides, for the first time, a systematic investigation of the target TFs critical to DHI-mediated protection against cerebral ischemia, as well as reveals more potential therapeutic targets for ischemic stroke.

    Disposal of dead pigs by pig farmers may have a direct impact on pork safety, public health, and the ecological environment in China. Drawing on the existing literature, this study analyzed and summarized the main factors that could affect the disposal of dead pigs by pig farmers by conducting a survey of 654 pig farmers in Funing County, Jiangsu Province, China. The purpose of this analysis was to investigate the disposal of dead pigs in China and provide useful regulatory strategies for the government. The interrelationships among dimensions and factors that affect the disposal of dead pigs by farmers were analyzed, and critical factors were identified by a hybrid multi-criteria decision-making method, which is a combination of decision-making trial and evaluation laboratory (DEMATEL) and analytic network process (ANP). Our results demonstrated that production characteristics were the most important dimensions and that costs and profits, scale of farming, pattern of farming, knowledge of relevant laws and regulations, and knowledge of pig disease and prevention were the five most critical factors affecting the disposal of dead pigs by farmers in China at this stage. The significance of this study lies in further discussing some management policies for the Chinese government regarding strengthen regulation of disposing dead pigs.

  1. Spatial attention, preview, and popout: which factors influence critical spacing in crowded displays?

    PubMed

    Scolari, Miranda; Kohnen, Andrew; Barton, Brian; Awh, Edward

    2007-02-14

    Crowding refers to the phenomenon in which nearby distractors impede target processing. This effect is reduced as target-distractor distance increases, and it is eliminated entirely at a distance that is labeled the critical spacing point. Attention, distractor preview, and popout are each known to facilitate processing in crowded displays. Eight experiments examined whether this is accomplished via a reduction in critical spacing. Attention was manipulated via spatial cueing, whereby a peripheral cue elicited a stimulus-driven shift of attention. Distractor preview was examined by manipulating whether the crowding distractors were presented prior to or simultaneous with the target. Popout was examined by manipulating whether there was a salient color difference between the target and distractors. As demonstrated in previous studies, we found robust benefits of spatial cueing, preview, and popout in crowded displays. However, although spatial cueing led to robust improvements in target discrimination, there was no reduction in critical spacing for attended stimuli. By contrast, both preview and popout caused large reductions in critical spacing. These disparate results indicate that attention improves target discrimination in crowded displays in a qualitatively different manner than do the other factors.

    The mechanical efficiency of stepping to recover balance can be expressed by a biomechanical model that includes the trunk inclination angle and the angle of the leg at the instant of stepping-foot contact. The aim of the present study was to test the hypothesis that this model would accurately predict the successfulness of recovery attempts (recovery vs. falls) following large backward perturbations. Ten young participants were exposed to a series of 12 very large postural perturbations in the backward direction by means of a support-surface translation. At the instant of stepping-foot contact, we calculated the trunk inclination angle and the angle of the stepping leg with the vertical. Reaction time, step duration, step velocity and step length were also determined. A logistic regression analysis revealed that the model with leg and trunk inclination angles accurately predicted successful recovery, with a more forward tilted trunk and a further backward positioned leg increasing the probability of success. The set of spatiotemporal step variables was significantly less predictive. Over the course of the experiment, participants gradually became more successful in recovering balance, which coincided with an increase in leg but not in trunk angles. In conclusion, the body configuration at the instant of first stepping-foot contact accurately predicted successful balance recovery after a backward postural perturbation. Given the observation that participants improved their performance by increasing their leg angles, which suggests that it may be easier to improve this variable, compared to the trunk angle, by exercise interventions.

    One third of all practicing physicians are currently working in one of the 400 German health care networks. These physicians' networks bring together GPs and specialists and cooperate with different partners, for example, nursing homes, hospitals, and self-help groups. To increase the quality and the efficiency of care and patient satisfaction by improving the collaboration and communication between physicians and other health care providers.The example of the accountable care organization "Gesundheitsnetz Qualität und Effizienz" (QuE; Health Quality and Efficiency Network) in Nuremberg is used to show that it is possible to achieve an increase in efficiency while providing above-average quality of care and achieving high patient satisfaction. Additionally, the article deals with the status quo, the core objectives, and the key activities of previous generations of health care networks. Quality indicators, satisfaction surveys, and economic parameters are the basis for measuring and representing the above-average performance of physicians' networks. Regional health care networks offer an entire range of patient care, from outpatients and inpatients to the complementary sector, and thereby have excellent prospects for playing an even more important role in the German health care system. The key success factors are: the consideration of specific regional characteristics, their proximity to the patient, and consistent patient orientation.

    Recent concerns over a crisis of identity and legitimacy in community-based natural resource management (CBNRM) have emerged following several decades of documented failure. A substantial literature has developed on the reasons for failure in CBNRM. In this paper, we complement this literature by considering these factors in relation to two successful CBNRM case studies. These cases have distinct differences, one focusing on the conservation of hirola in Kenya on community-held trust land and the other focusing on remnant vegetation conservation from grazing pressure on privately held farm land in Australia. What these cases have in common is that both CBNRM projects were initiated by local communities with strong attachments to their local environments. The projects both represent genuine community initiatives, closely aligned to the original aims of CBNRM. The intrinsically high level of "ownership" held by local residents has proven effective in surviving many challenges which have affected other CBNRM projects: from impacts on local livelihoods to complex governance arrangements involving non-government organizations and research organizations. The cases provide some signs of hope among broader signs of crisis in CBNRM practice.

    Use of successive alkalinity-producing systems (SAPS) for treatment of acidic mine drainage (AMD) has grown in recent years. However, inconsistent performance has hampered widespread acceptance of this technology. This research was conducted to determine the influence of system design and influent AMD chemistry on net alkalinity generation by SAPS. Monthly observations were obtained from eight SAPS cells in southern West Virginia and southwestern Virginia. Analysis of these data revealed strong, positive correlations between net alkalinity generation and three variables: the natural log of limestone residence time, influent dissolved Fe concentration, and influent non-Mn acidity. A statistical model was constructed to describe SAPS performance. Subsequent analysis of data obtained from five systems in western Pennsylvania (calibration data set) was used to reevaluate the model form, and the statistical model was adjusted using the combined data sets. Limestone residence time exhibited a strong, positive logarithmic correlation with net alkalinity generation, indicating net alkalinity generation occurs most rapidly within the first few hours of AMD-limestone contact and additional residence time yields diminishing gains in treatment. Influent Fe and non-Mn acidity concentrations both show strong positive linear relationships with net alkalinity generation, reflecting the increased solubility of limestone under acidic conditions. These relationships were present in the original and the calibration data sets, separately, and in the statistical model derived from the combined data set. In the combined data set, these three factors accounted for 68% of the variability in SAPS systems performance. PMID:11401248

    The objective of this study was to investigate factors that influence the success of resynchronization protocols for bovines with and without progesterone supplementation. Cow synchronized and not found pregnant were randomly assigned to two resynchronization protocols: ovsynch without progesterone (P4) supplementation (n = 66) or with exogenous P4 administered from Days 0 to 7 (n = 67). Progesterone levels were measured on Days 0 and 7 of these protocols as well as 4 and 5 days post-insemination. Progesterone supplementation raised the P4 levels on Day 7 (p < 0.05), but had no overall effect on resynchronization rates (RRs) or pregnancy per artificial insemination (P/AI). However, cows with Body Condition Score (BCS) > 3.5 had increased P/AI values while cows with BCS < 2.75 had decreased P/AI rates after P4 supplementation. Primiparous cows had higher P4 values on Day 7 than pluriparous animals (p = 0.04) and tended to have higher RRs (p = 0.06). Results of this study indicate that progesterone supplementation in resynchronization protocols has minimal effects on outcomes. Parity had an effect on the levels of circulating progesterone at initiation of the protocol, which in turn influenced the RR. PMID:25293490

  8. A reappraisal of success factors for Olympic cross-country skiing.

    Cross-country (XC) skiing has been an Olympic event since the first Winter Games in Chamonix, France, in 1924. Due to more effective training and tremendous improvements in equipment and track preparation, the speed of Olympic XC-ski races has increased more than that of any other Olympic endurance sport. Moreover, pursuit, mass-start, and sprint races have been introduced. Indeed, 10 of the 12 current Olympic competitions in XC skiing involve mass starts, in which tactics play a major role and the outcome is often decided in the final sprint. Accordingly, reappraisal of the success factors for performance in this context is required. The very high aerobic capacity (VO2max) of many of today's world-class skiers is similar that of their predecessors. At the same time, the new events provide more opportunities to profit from anaerobic capacity, upper-body power, high-speed techniques, and "tactical flexibility." The wide range of speeds and slopes involved in XC skiing requires skiers to continuously alternate between and adapt different subtechniques during a race. This technical complexity places a premium on efficiency. The relative amounts of endurance training performed at different levels of intensity have remained essentially constant during the past 4 decades. However, in preparation for the Sochi Olympics in 2014, XC skiers are performing more endurance training on roller skis on competition-specific terrain, placing greater focus on upper-body power and more systematically performing strength training and skiing at high speeds than previously.

    PlantingScience is an award-winning program recognized for its innovation and use of computer-supported scientist mentoring. Science learners work on inquiry-based experiments in their classrooms and communicate asynchronously with practicing plant scientist-mentors about the projects. The purpose of this study was to identify specific factors contributing to the program's effectiveness in engaging students. Using multiple data sources, grounded theory (Strauss and Corbin in Basics of qualitative research. Sage, Newbury Park, 1990) was used to develop a conceptual model identifying the central phenomenon, causal conditions, intervening conditions, strategies, contexts, and student outcomes of the project. Student motivation was determined to be the central phenomenon explaining the success of the program, with student empowerment, online mentor interaction, and authenticity of the scientific experiences serving as causal conditions. Teachers contributed to student motivation by giving students more freedom, challenging students to take projects deeper, encouraging, and scaffolding. Scientists contributed to student motivation by providing explanations, asking questions, encouraging, and offering themselves as partners in the inquiry process. Several positive student outcomes of the program were uncovered and included increased positivity, greater willingness to take projects deeper, better understanding of scientific concepts, and greater commitments to collaboration. The findings of this study provide relevant information on how to develop curriculum, use technology, and train practitioners and mentors to utilize strategies and actions that improve learners' motivation to engage in authentic science in the classroom.

    Changes in the density and species composition of planktonic rotifers as well as their relationship to several environmental variables were studied at Dadian Lake, a shallow subtropical lake, which was completely dredged and reconstructed. Samples were taken monthly (2006–2009) at five stations. The total rotifer abundance exponentially declined and reached a relatively stable stage in 2009. Polyarthra dolichoptera and Trichocerca pusilla dominated the rotifer community in most seasons. TN, TP, and CODMn went down at the beginning of the monitoring period, rebounded in the second winter, and then decreased and reached a stable state in 2009. CCA showed that the most significant variations were caused by fluctuations in temperature, CODMn, SRP, and NO2-N. The rotifer community experienced a two-stage succession and the difference of species between the stages was exhibited during warm seasons. GAMs indicated that the selected factors were responsible for 64.8% of the total rotifer abundance variance and 16.5~64.3% of the variances of individual species abundance. Most of the environmental parameters had effects on rotifer abundance that could only be described by complicated curves, characterised by unimodality and bimodality instead of linearity. Our study highlighted the temperature influence on rotifer species composition and total abundance in subtropical lakes. PMID:23864829

    Swimming is one of the most popular recreational and competitive sporting activities. In the 2013/2014 swimming season, 9630 men and 12,333 women were registered with the National Collegiate Athletics Association in the USA. The repetitive nature of the swimming stroke and demanding training programs of its athletes raises a number of concerns regarding incidence and severity of injuries that a swimmer might experience during a competitive season. A number of risk factors have previously been identified but the level of evidence from individual studies, as well as the level of certainty that these factors predispose a swimmer to pain and injury, to our knowledge has yet to be critically evaluated in a systematic review. Therefore, the primary objective of this review is to conduct a systematic review to critically assess the published evidence for risk factors that may predispose a swimmer to shoulder pain and injury. Three electronic databases, ScienceDirect, PubMed and SpringerLink, were searched using keywords "(Injury OR pain) AND (Swim*)" and "(Shoulder) AND (Swim*)". Based on the inclusion and exclusion criteria, 2731 unique titles were identified and were analyzed to a final 29 articles. Only articles with a level of evidence of I, II and III were included according to robust study design and data analysis. The level of certainty for each risk factor was determined. No studies were determined to have a high level of certainty, clinical joint laxity and instability, internal/external rotation, previous history of pain and injury and competitive level were determined to have a moderate level of certainty. All other risk factors were evaluated as having a low level of certainty. Although several risk factors were identified from the reviewed studies, prospective cohort studies, larger sample sizes, consistent and robust measures of risk should be employed in future research.

    Introduction Malnutrition is a frequent problem associated with detrimental clinical outcomes in critically ill patients. To avoid malnutrition, most studies focus on the prevention of inadequate nutrition delivery, whereas little attention is paid to the potential role of exocrine pancreatic insufficiency (EPI). In this trial, we aim to evaluate the prevalence of EPI and identify its potential risk factors in critically ill adult patients without preexisting pancreatic diseases. Methods In this prospective cross-sectional study, we recruited 563 adult patients with critical illnesses. All details of the patients were documented, stool samples were collected three to five days following the initiation of enteral nutrition, and faecal elastase 1 (FE-1) concentrations were assayed using an enzyme-linked immunosorbent assay kit. Blood samples were also taken to determine serum amylase and lipase activity. Results The percentages of recruited patients with EPI (FE-1 concentration <200 μg/g) and severe EPI (FE-1 concentration <100 μg/g) were 52.2% and 18.3%, respectively. The incidences of steatorrhea were significantly different (P < 0.05) among the patients without EPI, with moderate EPI (FE-1 concentration = 100 to 200 μg/g) and severe EPI (FE-1 concentration < 100 μg/g). Both multivariate logistic regression analysis and z-tests indicated that the occurrence of EPI was closely associated with shock, sepsis, diabetes, cardiac arrest, hyperlactacidemia, invasive mechanical ventilation and haemodialysis. Conclusions More than 50% of critically ill adult patients without primary pancreatic diseases had EPI, and nearly one-fifth of them had severe EPI. The risk factors for EPI included shock, sepsis, diabetes, cardiac arrest, hyperlactacidemia, invasive mechanical ventilation and haemodialysis. Trial registration NCT01753024 PMID:23924602

    To determine what patient characteristics are associated with prolonged emergency department (ED) length-of-stay (LOS) for surgical critical care patients, the charts of 169 patients admitted from the ED directly to the operating room (OR) or intensive care unit (ICU) during a 6-week period in 1993 were reviewed. The ED record was reviewed for documentation of factors that might be associated with prolonged ED LOS, such as use of computed tomographic (CT), radiology special procedures, and the number of plain radiographs and consultants. ED LOS was considered to be the time from triage until a decision was made to admit the patient. Using a Cox proportional hazards model, use of CT and special procedures were the strongest independent predictors of prolonged ED length-of-stay. The number of plain radiographs and consultants had only a minimal effect. Use of a protocol-driven trauma evaluation system was associated with a shorter ED LOS. In addition to external factors that affect ED overcrowding, ED patient management decisions may also be associated with prolonged ED length-of-stay. Such ED-based factors may be more important in surgical critical care patients, whose overall ED LOS is affected more by the length of the ED work-up rather than the time spent waiting for a ICU bed or operating suite.

    Industry predictions focus on future e-hospitals that will integrate all stakeholders into a seamless network, allowing data to be shared. The Health Level Seven (HL7) is a standard for the interchange of data within the healthcare industry. It simplifies communication interfaces and allows the interoperability among heterogeneous applications. Although the benefits of adopting HL7 are well known, only a few hospitals in Taiwan have actually adopted it. What are the reasons behind the hospitals' lack of intention to adopt HL7? Most prior studies on HL7 have focused on technical issues and general overlooked the managerial side. This has caused a lack of understanding of factors influencing hospitals' decision on HL7 adoption. In fact, main reasons behind a hospital's decision on whether to adopt an innovative technology are more often related to organizational than purely technical issues. Hence, we pay our attention to these organizational considerations over HL7 adoption. Based on the Innovation Diffusion Theory, we proposed a research model to explore the critical factors influencing Taiwan hospitals' adoption intention of HL7. 472 questionnaires were distributed to all accredited hospitals in Taiwan and 122 were returned. The valid response rate was 25.21% (119). Factor analysis, logistic regression and Pearson Chi-square test were conducted to verify the research model. The results showed that environmental pressure, top management attitude towards HL7, staff's technology capability, system integrity, and hospital's scale were critical factors influencing hospitals' intention on whether to adopt HL7. The research findings provided the government, the healthcare industry, the hospital administrators and the academia with practical and theoretical references. These factors should be considered in planning promotion plan to encourage hospital adoption of HL7. This study also opens up a new research direction as well as a new viewpoint, and consequentially

    Bone substitutes have been a critical issue as the natural source can seldom provide enough bone to support full healing. No bone substitute complies with all necessary functions and characteristics that an autograft does. Polyurethane sponges have been used as a surgical alternative to cancellous bone grafts for critical bone defect donor sites. Critical bone defects were created on the tibial tuberosity and iliac crest using an ovine model. In group I (control-untreated), no bone regeneration was observed in any animal. In group II (defects left empty but covered with a microporous polymeric membrane), the new bone bridged the top ends in all animals. In groups III and IV, bone defects were implanted with polyurethane scaffolds modified with biologically active compounds, and bone regeneration was more efficient than in group II. In groups III and IV there were higher values of bone regeneration specific parameters used for evaluation (P < 0.05) although the comparison between these groups was not possible. The results obtained in this study suggest that biodegradable polyurethane substitutes modified with biologically active substances may offer an alternative to bone graft, reducing donor site morbidity associated with autogenous cancellous bone harvesting.

    This report provides a further analysis of the first year weight losses in the Look AHEAD (Action for Health in Diabetes) study and identifies factors associated with success. Participants were a total of 5,145 men and women with type 2 diabetes who were recruited at 16 sites and randomly assigned to an intensive lifestyle intervention (ILI) or a control condition, Diabetes Support and Education (DSE). During year 1, participants in ILI received comprehensive diet and physical activity counseling in a total of 42 group and individual sessions, compared with three educational sessions for DSE participants. As reported previously, at the end of the year, ILI participants lost 8.6% of initial weight, compared to 0.7% for DSE (P < 0.001). Within the ILI group, all racial/ethnic groups achieved clinically significant weight losses (>5.5%), although there were significant differences among groups. For the year, ILI participants attended an average of 35.4 treatment sessions and reported exercising a mean of 136.6 min/week and consuming a total of 360.9 meal replacement products. Greater self-reported physical activity was the strongest correlate of weight loss, followed by treatment attendance and consumption of meal replacements. The use of orlistat, during the second half of the year, increased weight loss only marginally in those ILI participants who had lost <5% of initial weight during the first 6 months and chose to take the medication thereafter as a toolbox option. The lifestyle intervention was clinically effective in all subsets of an ethnically and demographically diverse population.

    This report provides a further analysis of the year 4 weight losses in the Look AHEAD (Action for Health in Diabetes) study and identifies factors associated with long-term success. A total of 5145 overweight/obese men and women with type 2 diabetes were randomly assigned to an intensive lifestyle intervention (ILI) or a usual care group, referred to as Diabetes Support and Education (DSE). ILI participants were provided approximately weekly group or individual treatment in year 1; continued but less frequent contact was provided in years 2–4. DSE participants received three group educational sessions in all years. As reported previously, at year 4, ILI participants lost an average of 4.7% of initial weight, compared with 1.1% for DSE (p<0.0001). More ILI than DSE participants lost ≥5% (46% vs 25%, p<0.0001) and ≥10% (23% vs 10%, p<0.0001) of initial weight. Within the ILI, acheivement of both the 5% and 10% categorical weight losses at year 4 was strongly related to meeting these goals at year 1. A total of 887 participants in ILI lost ≥10% at year 1, of whom 374 (42.2%) achieved this loss at year 4. Participants who maintained the loss, compared with those who did not, attended more treatment sessions and reported more favorable physical activity and food intake at year 4. These results provide critical evidence that a comprehensive lifestyle intervention can induce clinically significant weight loss (i.e., ≥5%) in overweight/obese participants with type 2 diabetes and maintain this loss in more than 45% of patients at 4 years.

More ILI than DSE participants lost ≥ 5% (46% vs. 25%, P < 0.0001) and ≥ 10% (23% vs. 10%, P < 0.0001) of initial weight. Within the ILI, achievement of both the 5% and 10% categorical weight losses at year 4 was strongly related to meeting these goals at year 1. A total of 887 participants in ILI lost ≥ 10% at year 1, of whom 374 (42.2%) achieved this loss at year 4. Participants who maintained the loss, compared with those who did not, attended more treatment sessions and reported more favorable physical activity and food intake at year 4. These results provide critical evidence that a comprehensive lifestyle intervention can induce clinically significant weight loss (i.e., ≥ 5%) in overweight/obese participants with type 2 diabetes and maintain this loss in more than 45% of patients at 4 years.

    This report provides a further analysis of the year 4 weight losses in the Look AHEAD (Action for Health in Diabetes) study and identifies factors associated with long-term success. A total of 5,145 overweight/obese men and women with type 2 diabetes were randomly assigned to an intensive lifestyle intervention (ILI) or a usual care group, referred to as Diabetes Support and Education (DSE). ILI participants were provided approximately weekly group or individual treatment in year 1; continued but less frequent contact was provided in years 2-4. DSE participants received three group educational sessions in all years. As reported previously, at year 4, ILI participants lost an average of 4.7% of initial weight, compared with 1.1% for DSE (P < 0.0001). More ILI than DSE participants lost ≥ 5% (46% vs. 25%, P < 0.0001) and ≥ 10% (23% vs. 10%, P < 0.0001) of initial weight.

    As business process re-engineering (BPR) is an important foundation to ensure the success of enterprise systems, this study would like to investigate the relationships among BPR implementation, BPR success factors, and business performance for logistics companies. Our empirical findings show that BPR companies outperformed non-BPR companies, not only on information processing, technology applications, organisational structure, and co-ordination, but also on all of the major logistics operations. Comparing the different perceptions of the success factors for BPR, non-BPR companies place greater emphasis on the importance of employee involvement while BPR companies are more concerned about the influence of risk management. Our findings also suggest that management attitude towards BPR success factors could affect performance with regard to technology applications and logistics operations. Logistics companies which have not yet implemented the BPR approach could refer to our findings to evaluate the advantages of such an undertaking and to take care of those BPR success factors affecting performance before conducting BPR projects.

  9. The role of habitat factors in successful invasion of alien plant Acer negundo in riparian zones.

    Ash-leaved maple (Acer negundo) is one of the most invasive species occurring in riparian zones. The invasion is especially effective in disturbed areas, as the plant favours anthropogenic sites. The plant was also observed to be able to penetrate into sandy bars, also those separated from the land, inaccessible to people. It's removal is time-consuming and laborious, often involves damage done to sensitive vegetation and the results are doubtful, as the plant quickly regenerates. The invasion patterns and establishment of ash-leaved maple in natural ecosystems are poorly investigated. The aim of this study was to test how habitat factors such as: light availability, soil characteristics and competition contribute to ash-leaved maple effective colonization of natural sand bars free from anthropogenic pressure. In 2014 sand bars located in Vistula River Valley in Warsaw were inventoried and classified basing on their development stage as 1 - initial, 2 - unstable, 3 - stable. Apart from the occurrence of the invasive ash-leaved maple the plants competing with it were recognized and the percentage of the shoots of shrubs and herbaceous plants was estimated. PAR was measured at ground level and 1 meter above ground, the thickness of organic layer formed on the top of the sand was also measured as the indicator of sand bar development stage. The maple's survival in extremely difficult conditions resembles the strategy of willows and poplars naturally occurring in the riparian zones, which are well adapted to this environment. The success of invasion strongly depends on the plants establishment during sand bars initial stage of development. The seedlings growth correlates with the age of the sand bar (r1=0,41, r2=0,42 i r3=0,57). The colonization lasts for 4-6 years and the individuals start to cluster in bigger parches. After that period the maple turns into the phase of competition for space. Habitat factors such as shading (r2=0,41 i r3=0,51) and organic layer

    The purpose of this calculation is to develop additional Biosphere Dose Conversion Factors (BDCFs) for a reasonably maximally exposed individual (RMEI) for the periods 10,000 years and 1,000,000 years after the repository closure. In addition, Biosphere Dose Conversion Factors for the average member of a critical group are calculated for those additional radionuclides postulated to reach the environment during the period after 10,000 years and up to 1,000,000 years. After the permanent closure of the repository, the engineered systems within the repository will eventually lose their abilities to contain radionuclide inventory, and the radionuclides will migrate through the geosphere and eventually enter the local water table moving toward inhabited areas. The primary release scenario is a groundwater well used for drinking water supply and irrigation, and this calculation takes these postulated releases and follows them through various pathways until they result in a dose to either a member of critical group or a reasonably maximally exposed individual. The pathways considered in this calculation include inhalation, ingestion, and direct exposure.

    The aim of this research is to explore factors influencing the management decisions to adopt human resource information system (HRIS) in the hospital industry of Bangladesh—an emerging developing country. To understand this issue, this paper integrates two prominent adoption theories—Human-Organization-Technology fit (HOT-fit) model and Technology-Organization-Environment (TOE) framework. Thirteen factors under four dimensions were investigated to explore their influence on HRIS adoption decisions in hospitals. Employing non-probability sampling method, a total of 550 copies of structured questionnaires were distributed among HR executives of 92 private hospitals in Bangladesh. Among the respondents, usable questionnaires were 383 that suggesting a valid response rate of 69.63%. We classify the sample into 3 core groups based on the HRIS initial implementation, namely adopters, prospectors, and laggards. The obtained results specify 5 most critical factors i.e. IT infrastructure, top management support, IT capabilities of staff, perceived cost, and competitive pressure. Moreover, the most significant dimension is technological dimension followed by organisational, human, and environmental among the proposed 4 dimensions. Lastly, the study found existence of significant differences in all factors across different adopting groups. The study results also expose constructive proposals to researchers, hospitals, and the government to enhance the likelihood of adopting HRIS. The present study has important implications in understanding HRIS implementation in developing countries. PMID:27494334

    The literature shows that delayed admission to the intensive care unit (ICU) and discharge delays from the ICU are associated with increased adverse events and higher costs. Identifying factors related to delays will provide information to practice improvements, which contribute to better patient outcomes. The aim of this integrative review was to explore the incidence of patients' admission and discharge delays in critical care and to identify organisational factors associated with these delays. Seven studies were included. The major findings are as follows: (1) explanatory research about discharge delays is scarce and one study on admission delays was found, (2) delays are a common problem mostly due to organisational factors, occurring in 38% of admissions and 22-67% of discharges, and (3) redesigning care processes by improving information management and coordination between units and interdisciplinary teams could reduce discharge delays. In conclusion, patient outcomes can be improved through efficient and safe care processes. More exploratory research is needed to identify factors that contribute to admission and discharge delays to provide evidence for clinical practice improvements. Shortening delays requires an interdisciplinary and multifaceted approach to the whole patient flow process. Conclusions should be made with caution due to the limited number of articles included in this review.

    King eider (Somateria spectabilis) populations have declined markedly in recent decades for unknown reasons. Nest survival is one component of recruitment, and a female's chance of reproductive success increases with her ability to choose an appropriate nesting strategy. We estimated variation in daily nest survival of king eiders at 2 sites, Teshekpuk and Kuparuk, Alaska, USA, 2002-2005. We evaluated both a priori and exploratory competing models of nest survival that considered importance of nest concealment, seclusion, and incubation constancy as strategies to avoid 2 primary egg predators, avian (Larus spp., Stercorarius spp., and Corvus corax) and fox (Alopex lagopus). We used generalized nonlinear techniques to examine factors affecting nest survival rates and information-theoretic approaches to select among competing models. Estimated nest survival, accounting for a nest visitation effect, varied considerably across sites and years (0.21-0.57); however, given our small sample size, much of this variation maybe attributable to sampling variation (??process = 0.007, 95% CI: 0.003-0.070). Nest survival was higher at Kuparuk than Teshekpuk in all years; however, due to the correlative nature of our data, we cannot determine the underlying causes with any certainty. We found mixed support for the concealed breeding strategy, females derived no benefit from nesting in areas with more willow (Salix spp.; measure of concealment) except that the observer effect diminished as willow cover increased. We suggest these patterns are due to conflicting predation pressures. Nest survival was not higher on islands (measure of seclusion) or with increased incubation constancy but was higher post-fox removal, indicating that predator control on breeding grounds could be a viable management option. Nest survival was negatively affected by our nest visitations, most likely by exposing the nest to avian scavengers. We recommend precautions be taken to limit the effects of nest

    Background: Nowadays, using new information technology (IT) has provided remarkable opportunities to decrease medical errors, support health care specialist, increase the efficiency and even the quality of patient’s care and safety. Objectives: The purpose of this study was the identification of Hospital Information System (HIS) success and failure factors and the evaluation methods of these factors. This research emphasizes the need to a comprehensive evaluation of HISs which considers a wide range of success and failure factors in these systems. Materials and Methods: We searched for relevant English language studies based on keywords in title and abstract, using PubMed, Ovid Medline (by applying MeSH terms), Scopus, ScienceDirect and Embase (earliest entry to march 17, 2012). Studies which considered success models and success or failure factors, or studied the evaluation models of HISs and the related ones were chosen. Since the studies used in this systematic review were heterogeneous, the combination of extracted data was carried out by using narrative synthesis method. Results: We found 16 articles which required detailed analysis. Finally, the suggested framework includes 12 main factors (functional, organizational, behavioral, cultural, management, technical, strategy, economy, education, legal, ethical and political factors), 67 sub factors, and 33 suggested methods for the evaluation of these sub factors. Conclusions: The results of the present research indicates that the emphasis of the HIS evaluation moves from technical subjects to human and organizational subjects, and from objective to subjective issues. Therefore, this issue entails more familiarity with more qualitative evaluation methods. In most of the reviewed studies, the main focus has been laid on the necessity of using multi-method approaches and combining methods to obtain more comprehensive and useful results. PMID:24693386

    The use of therapeutic drug monitoring (TDM) to optimize beta-lactam dosing in critically ill patients is growing in popularity, although there are limited data describing the potential impact of altered protein binding on achievement of target concentrations. The aim of this study was to compare the measured unbound concentration to the unbound concentration predicted from published protein binding values for seven beta-lactams using data from blood samples obtained from critically ill patients. From 161 eligible patients, we obtained 228 and 220 plasma samples at the midpoint of the dosing interval and trough, respectively, for ceftriaxone, cefazolin, meropenem, piperacillin, ampicillin, benzylpenicillin, and flucloxacillin. The total and unbound beta-lactam concentrations were measured using validated methods. Variabilities in both unbound and total concentrations were marked for all antibiotics, with significant differences being present between measured and predicted unbound concentrations for ceftriaxone and for flucloxacillin at the mid-dosing interval (P < 0.05). The predictive performance for calculating unbound concentrations using published protein binding values was poor, with bias for overprediction of unbound concentrations for ceftriaxone (83.3%), flucloxacillin (56.8%), and benzylpenicillin (25%) and underprediction for meropenem (12.1%). Linear correlations between the measured total and unbound concentrations were observed for all beta-lactams (R2 = 0.81 to 1.00; P < 0.05) except ceftriaxone and flucloxacillin. The percent protein binding of flucloxacillin and the plasma albumin concentration were also found to be linearly correlated (R2 = 0.776; P < 0.01). In conclusion, significant differences between measured and predicted unbound drug concentrations were found only for the highly protein-bound beta-lactams ceftriaxone and flucloxacillin. However, direct measurement of unbound drug in research and clinical practice is suggested for selected

  20. Group Dynamics as a Critical Component of Successful Space Exploration: Conceptual Theory and Insights from the Biosphere 2 Closure Experiment

    NASA Astrophysics Data System (ADS)

    Nelson, Mark; Allen, John P.

    As space exploration and eventually habitation achieves longer durations, successfully managing group dynamics of small, physically isolated groups will become vital. The paper summarizes important underlying research and conceptual theory and how these manifested in a well-documented example: the closure experiments of Biosphere 2. Key research breakthroughs in discerning the operation of small human groups comes from the pioneering work of W.R. Bion. He discovered two competing modalities of behavior. The first is the “task-oriented” or work group governed by shared acceptance of goals, reality-thinking in relation to time, resources and rational, and intelligent management of challenges presented. The opposing, usually unconscious, modality is what Bion called the “basic-assumption” group and alternates between three “group animal” groups: dependency/kill the leader; fight/flight and pairing. If not dealt with, these dynamics work to undermine and defeat the conscious task group’s goal achievement. The paper discusses crew training and selection, various approaches to structuring the work and hierarchy of the group, the importance of contact with a larger population through electronic communication and dealing with the “us-them” syndrome frequently observed between crew and Mission Control. The experience of the first two year closure of Biosphere 2 is drawn on in new ways to illustrate vicissitudes and management of group dynamics especially as both the inside team of biospherians and key members of Mission Control had training in working with group dynamics. Insights from that experience may help mission planning so that future groups in space cope successfully with inherent group dynamics challenges that arise.

    2016-07-01

    Landfill mining has been proposed as an innovative strategy to mitigate environmental risks associated with landfills, to recover secondary raw materials and energy from the deposited waste, and to enable high-valued land uses at the site. The present study quantitatively assesses the importance of specific factors and conditions for the net contribution of landfill mining to global warming using a novel, set-based modeling approach and provides policy recommendations for facilitating the development of projects contributing to global warming mitigation. Building on life-cycle assessment, scenario modeling and sensitivity analysis methods are used to identify critical factors for the climate impact of landfill mining. The net contributions to global warming of the scenarios range from -1550 (saving) to 640 (burden) kg CO2e per Mg of excavated waste. Nearly 90% of the results' total variation can be explained by changes in four factors, namely the landfill gas management in the reference case (i.e., alternative to mining the landfill), the background energy system, the composition of the excavated waste, and the applied waste-to-energy technology. Based on the analyses, circumstances under which landfill mining should be prioritized or not are identified and sensitive parameters for the climate impact assessment of landfill mining are highlighted.

  12. A critical examination of the U.S. nursing shortage: contributing factors, public policy implications.

    2009-01-01

    BACKGROUND. Despite short-lived periods of adequacy in nurse availability, the nursing shortage has endured. In order to better understand the myriad factors that influence the current shortage of nurses, as well as possible solutions, this project addresses the influence of social factors and government policy on nurse staffing inadequacy. When the government intervenes in a philosophically free-market economy, the assumption is that a problem, such as the current nursing shortage, could not be solved without such intervention. PURPOSE. Nursing care arguably falls into the realm of protecting the common good, and therefore requires government oversight. We provide a critical analysis of policy intervention efforts into the nursing shortage debate by examining the passage of legislation, the provision of educational assistance, and the establishment of minimum staffing requirements and minimum quality standards for reimbursement, which all impact nursing supply and demand. RESULTS. Arguments supporting and opposing policy intervention in general, and its impact on the overall provision of nursing care in the United States, were examined. Without policy incentive to place financial value on the quality of care provided by nurses, a simple increase in the number of available nurses is unlikely to solve the current problem. IMPLICATIONS. Important considerations that should be factored into policy creation include measurement and compensation for quality care, the nature of recruitment efforts of new nurses, and the complex nature of a nursing work.

    BACKGROUND. Despite short-lived periods of adequacy in nurse availability, the nursing shortage has endured. In order to better understand the myriad factors that influence the current shortage of nurses, as well as possible solutions, this project addresses the influence of social factors and government policy on nurse staffing inadequacy. When the government intervenes in a philosophically free-market economy, the assumption is that a problem, such as the current nursing shortage, could not be solved without such intervention. PURPOSE. Nursing care arguably falls into the realm of protecting the common good, and therefore requires government oversight. We provide a critical analysis of policy intervention efforts into the nursing shortage debate by examining the passage of legislation, the provision of educational assistance, and the establishment of minimum staffing requirements and minimum quality standards for reimbursement, which all impact nursing supply and demand. RESULTS. Arguments supporting and opposing policy intervention in general, and its impact on the overall provision of nursing care in the United States, were examined. Without policy incentive to place financial value on the quality of care provided by nurses, a simple increase in the number of available nurses is unlikely to solve the current problem. IMPLICATIONS. Important considerations that should be factored into policy creation include measurement and compensation for quality care, the nature of recruitment efforts of new nurses, and the complex nature of a nursing work.

    Core binding factor β (Cbfβ) is a partner protein of Runx family transcription factors with minimally characterized function in cartilage. Here we address the role of Cbfβ in cartilage by generating chondrocyte-specific Cbfβ-deficient mice (Cbfb(Δch/Δch) ) from Cbfb-floxed mice crossed with mice expressing Cre from the Col2a1 promoter. Cbfb(Δch/Δch) mice died soon after birth and exhibited delayed endochondral bone formation, shorter appendicular skeleton length with increased proliferative chondrocytes, and nearly absent hypertrophic chondrocyte zones. Immunohistochemical and quantitative real-time PCR analyses showed that the number and size of proliferative chondrocytes increased and the expression of chondrocyte maturation markers at the growth plates, including Runx2, osterix, and osteopontin, significantly diminished in Cbfb(Δch/Δch) mice compared to wild type mice. With regard to signaling pathways, both PTHrP-Ihh and BMP signaling were compromised in Cbfb(Δch/Δch) mice. Mechanistically, Cbfβ deficiency in chondrocytes caused a decrease of protein levels of Runx transcription factors by accelerating polyubiquitination-mediated proteosomal degradation in vitro. Indeed, Runx2 and Runx3, but not Runx1, decreased in Cbfb(Δch/Δch) mice. Collectively, these findings indicate that Cbfβ plays a critical role for chondrocyte differentiation through stabilizing Runx2 and Runx3 proteins in cartilage. PMID:26058470

    Objective To assess problem list completeness using an objective measure across a range of sites, and to identify success factors for problem list completeness. Methods We conducted a retrospective analysis of electronic health record data and interviews at ten healthcare organizations within the United States, United Kingdom, and Argentina who use a variety of electronic health record systems: four self-developed and six commercial. At each site, we assessed the proportion of patients who have diabetes recorded on their problem list out of all patients with a hemoglobin A1c elevation >= 7.0%, which is diagnostic of diabetes. We then conducted interviews with informatics leaders at the four highest performing sites to determine factors associated with success. Finally, we surveyed all the sites about common practices implemented at the top performing sites to determine whether there was an association between problem list management practices and problem list completeness. Results Problem list completeness across the ten sites ranged from 60.2% to 99.4%, with a mean of 78.2%. Financial incentives, problem-oriented charting, gap reporting, shared responsibility, links to billing codes, and organizational culture were identified as success factors at the four hospitals with problem list completeness at or near 90.0%. Discussion Incomplete problem lists represent a global data integrity problem that could compromise quality of care and put patients at risk. There was a wide range of problem list completeness across the healthcare facilities. Nevertheless, some facilities have achieved high levels of problem list completeness, and it is important to better understand the factors that contribute to success to improve patient safety. Conclusion Problem list completeness varies substantially across healthcare facilities. In our review of EHR systems at ten healthcare facilities, we identified six success factors which may be useful for healthcare organizations seeking to

    Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is an autosomal dominant autoinflammatory disease linked to chromosome 12p13 and, more specifically, with mutations within the tumor necrosis factor receptor superfamily, member 1A gene (TNFRSF1A gene). It is characterized by the presence of fever, abdominal pain, myalgia, arthralgia or arthritis, and skin rash. In this report, we describe the case of a patient with tumor necrosis factor receptor-associated periodic syndrome (TRAPS) treated successfully with the anti-interleukin-6 (anti-IL-6) receptor monoclonal antibody tocilizumab, while treatment with anti-TNF α etanercept and infliximab had both failed.

    COPD is a major cause of chronic morbidity and mortality throughout the world. Although tumor necrosis factor-α (TNF-α) has a critical role in the development of COPD, the role of different TNF receptors (TNFRs) in pulmonary emphysema has not been resolved. We aimed to clarify the role of TNFRs in the development of pulmonary emphysema. TNF-α transgenic mice, a murine model of COPD in which the mice spontaneously develop emphysema with a large increase in lung volume and pulmonary hypertension, were crossed with either TNFR1-deficient mice or TNFR2-deficient mice. After 6 months, the gross appearance of the lung, lung histology, and pulmonary and cardiac physiology were determined. In addition, the relationship between apoptosis and emphysema was investigated. Pulmonary emphysema-like changes disappeared with deletion of TNFR1. However, slight improvements were attained with deletion of TNFR2. Apoptotic cells in the interstitium of the lung were observed in TNF-α transgenic mice. The apoptotic signals through TNFR1 appear critical for the pathogenesis of pulmonary emphysema. In contrast, the inflammatory process has a less important role for the development of emphysema.

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

    2003-06-01

    Recent researches on temporomandibular disorders (TMD) have been focused on the interaction between physical and psychological factors. In this work, studies on the role of the latter have been critically reviewed and analysed. A number of works proved the existence of an association between TMD and anxiety, depression and stress, but none demonstrated causality of that relation. In consideration of that, debates are still open to discuss the possible predisposing, triggering and/or worsening role played by some psychic disorders in TMD subjects. Nevertheless, considering the usefulness of recent taxonomic proposals, it seems logical to adopt a broad therapeutic approach, directed both to the physical and psychic component of TMD symptoms. Besides, from this review it is underlined the need for controlled trials which, regardless of the causality of TMD-psychic disorders associations, definitively evaluate the efficacy of the various psychotherapy modalities proposed.

    The examination of which protective measures are the most appropriate to be implemented in order to prevent, protect against, respond to, and recover from attacks on critical infrastructures and key resources typically involves a comparison of the consequences that could occur when the protective measure is implemented to those that could occur when it is not. This report describes a framework for evaluation that provides some additional capabilities for comparing optional protective measures. It illustrates some potentially important time-dependent factors, such as the implementation rate, that affect the relative pros and cons associated with widespread implementation of protective measures. It presents example results from the use of protective measures, such as detectors and pretrained responders, for an illustrative biological incident. Results show that the choice of an alternative measure can depend on whether or not policy and financial support can be maintained for extended periods of time. Choice of a time horizon greatly influences the comparison of alternatives.

    Granulin epithelin precursor (GEP) is a new growth factor that functions in brain development, chondrogenesis, tissue regeneration, tumorigenesis, and inflammation. The goal of this study was to study whether GEP was critical for odontogenesis and amelogenesis both in vivo and in vitro. The in situ hybridization and immunohistochemistry data showed that GEP was expressed in both odontoblast and ameloblast cells postnatally. Knockdown of GEP by crossing U6-ploxPneo-GEP and Sox2-Cre transgenic mice led to a reduction of dentin thickness, an increase in predentin thickness, and a reduction in mineral content in enamel. The in vitro application of recombinant GEP up-regulated molecular markers important for odontogenesis (DMP1, DSPP, and ALP) and amelogenesis (ameloblastin, amelogenin and enamelin). In conclusion, both the in vivo and the in vivo data support an important role of GEP in tooth formation during postnatal development.

    The Ergonomic tridimensional analysis (ETdA) was developed to be used as an auxiliary tool on the ergonomic intervention. It was specially designed for commercial areas with free circulation of people. Due to that, the client, the third ETdA dimension, becomes an important element and their opinions relevant in the ergonomic analysis. The remains two ETdA dimensions, professionals and analyst, play an identical role as in the traditional occupational ergonomic analysis. For each of these dimensions, specific observation tools were assembled: an ETdA questionnaire, an evaluation form and a checklist for direct and indirect observations. The variables that allow the ETdA operability are identified as Ergonomic Factors (EFs). A case study is presented identifying, for each dimension, the critical EFs. This will allow the design of the weighting table, where the influence of each dimensions results is measured, stressing the important role of clients on ergonomic issues. PMID:22316794

    Tsetse flies undergo drastic fluctuations in their water content throughout their adult life history due to events such as blood feeding, dehydration and lactation, an essential feature of the viviparous reproductive biology of tsetse. Aquaporins (AQPs) are transmembrane proteins that allow water and other solutes to permeate through cellular membranes. Here we identify tsetse aquaporin (AQP) genes, examine their expression patterns under different physiological conditions (blood feeding, lactation and stress response) and perform functional analysis of three specific genes utilizing RNA interference (RNAi) gene silencing. Ten putative aquaporins were identified in the Glossina morsitans morsitans (Gmm) genome, two more than has been previously documented in any other insect. All organs, tissues, and body parts examined had distinct AQP expression patterns. Two AQP genes, gmmdripa and gmmdripb ( = gmmaqp1a and gmmaqp1b) are highly expressed in the milk gland/fat body tissues. The whole-body transcript levels of these two genes vary over the course of pregnancy. A set of three AQPs (gmmaqp5, gmmaqp2a, and gmmaqp4b) are expressed highly in the Malpighian tubules. Knockdown of gmmdripa and gmmdripb reduced the efficiency of water loss following a blood meal, increased dehydration tolerance and reduced heat tolerance of adult females. Knockdown of gmmdripa extended pregnancy length, and gmmdripb knockdown resulted in extended pregnancy duration and reduced progeny production. We found that knockdown of AQPs increased tsetse milk osmolality and reduced the water content in developing larva. Combined knockdown of gmmdripa, gmmdripb and gmmaqp5 extended pregnancy by 4-6 d, reduced pupal production by nearly 50%, increased milk osmolality by 20-25% and led to dehydration of feeding larvae. Based on these results, we conclude that gmmDripA and gmmDripB are critical for diuresis, stress tolerance and intrauterine lactation through the regulation of water and/or other

    1981-05-01

    The main factors limiting the performance of the peripheral parts of the visual system can be specified, and doing this clarifies the nature of the interpretive tasks that must be performed by the central parts of the system. It is argued that the critical factor that hinders development of better resolving power is the difficulty of confining light within the waveguide-like outer segment, and that for sensitivity this critical factor is the thermal decomposition of photosensitive pigments. Knowledge of these limits makes many surprising details of the eye intelligible. Understanding the difficulties posed by the narrow dynamic range of nerve fibres may give similar insight into the coding of the retinal image for transmission to the brain. Our level of understanding changes when we come to the visual cortex, for although we do not lack good anatomical and neurophysiological data, these do not make the principles of operation self-evident in the way that the structure of the eye immediately suggests that it is an image-forming device. The cortex converts the representation of the visual field that it receives into reliable knowledge of the world around us, and the trouble may be that we lack good models of how this can be done. A system that can respond to single quanta and resolve almost to the diffraction limit is unlikely to employ grossly inefficient methods for those higher functions upon which its whole utility depends, and so it is worth seeking out the limiting factors. The quality of human performance at certain higher perceptual tasks is high compared with the limit of reliable statistical inference; hence much of the sample of information available in a visual image must be effectively utilized. But there are strong limitations on the connectivity in the cortex, so that one is forced to consider how the relevant information can be collected together. Three stages of dealing with the visual image are proposed: the improvement of the cortical map in

    The main objective of this study, which evaluated a sample of first-year students enrolled at the University of Burgundy, France, in 2010-2011, is to understand the factors determining success in the first year of university. The originality of this research lies in the inclusion of specific indicators of students' skills when they start university within the explanatory models of educational achievement. These indicators include measures of academic performance (written comprehension skills) and cognitive abilities. While the impact of cognitive abilities on educational success has been examined at primary level in France, the present study is among the first to do this at higher education level, with the additional consideration of students' educational and social backgrounds. The results show the significant impact of educational background (repeated years, type of baccalaureate and baccalaureate grade) on success. The researchers also found that written comprehension skills and cognitive abilities alone play a limited role in explaining success, since the impacts of these variables are apparent throughout a student's educational career (and not just in higher education). Another finding was that subject choice based on specific career aspirations is an important factor associated with success - a significant insight which qualifies the impact of educational background.

    This study investigated the current management practices associated with stock herding dogs on Australian farms. A parallel goal was to determine whether these practices and the characteristics of the dog handlers were associated with success rates. Success rate refers to the proportion of dogs acquired by the farmer that were retained as working dogs. Data on a total of 4,027 dogs were obtained through The Farm Dog Survey which gathered information from 812 herding dog owners around Australia. Using logistic regression, significant associations were identified between success rate and seven variables: dog breed, housing method, trial participation, age of the dog at acquisition, electric collar use, hypothetical maximum treatment expenditure and the conscientiousness score of the owner's personality. These findings serve as a guide to direct further research into ways of optimising herding dog performance and welfare. They emphasise the importance of not only examining the genetic predispositions of the working dog but also the impact the handler can have on a dog's success in the workplace. PMID:25136828
