    Bowler, Mandy

    Self care can help people with long-term conditions take control of their lives. However, their interest and ability to engage with it may fluctuate over the course of an illness and many need support to undertake self care activities. A team of community matrons in NHS South of Tyne and Wear helped to develop and pilot an e-learning tool for staff, to remind them of the importance of self care and give advice on ways to support patients. The tool has since been rolled out to all staff groups.

    Efforts to improve healthcare and population health depend partly on the ability of health organisations to use research knowledge and participate in its production. We report the findings of a survey conducted to prioritise training needs among healthcare and public health staff, in relation to the production and implementation of research, across an applied health research collaboration. A questionnaire survey using a validated tool, the Hennessy-Hicks Training Needs Assessment Questionnaire. Participants rated 25 tasks on a five-point scale with regard to both their confidence in performing the task, and its importance to their role. A questionnaire weblink was distributed to a convenience sample of 35 healthcare and public health organisations in London and South East England, with a request that they cascade the information to relevant staff. 203 individuals responded, from 20 healthcare and public health organisations. None. Training needs were identified by comparing median importance and performance scores for each task. Individuals were also invited to describe up to three priority areas in which they require training. Across the study sample, evaluation; teaching; making do with limited resources; coping with change and managing competing demands were identified as key tasks. Assessing the relevance of research and learning about new developments were the most relevant research-related tasks. Participants' training priorities included evaluation; finding, appraising and applying research evidence; and data analysis. Key barriers to involvement included time and resources, as well as a lack of institutional support for undertaking research. We identify areas in which healthcare and public health professionals may benefit from support to facilitate their involvement in and use of applied health research. We also describe barriers to participation and differing perceptions of research between professional groups. Published by the BMJ Publishing Group Limited

    The aim of this study was to identify the factors contributing to lasting change in practice following a recovery-based training intervention for inpatient mental health rehabilitation staff. Staff training may help nurses and other staff groups in inpatient mental health rehabilitative settings to increase their recovery-oriented practice. There are no published reviews on the effectiveness of such training and few long-term evaluations. This review informed a realist evaluation of a specific intervention (GetREAL). Rapid realist review methodology was used to generate and prioritize programme theories. ASSIA, CINAHL, Cochrane Library, Medline, PsycINFO, Scopus, Web of Science and grey literature searches were performed in September 2014-March 2015 with no date restrictions. Stakeholders suggested further documents. GetREAL project documentation was consulted. Programme theory development took place iteratively with literature identification. Stakeholders validated and prioritized emerging programme theories and the prioritized theories were refined using literature case studies. Fifty-one relevant documents fed into 49 programme theories articulating seven mechanisms for lasting change. Prioritized mechanisms were: staff receptiveness to change; and staff feeling encouraged, motivated and supported by colleagues and management to change. Seven programme theories were prioritized and refined using data from four case studies. Lasting change can be facilitated by collaborative action planning, regular collaborative meetings, appointing a change agent, explicit management endorsement and prioritization and modifying organizational structures. Conversely, a challenging organizational climate, or a prevalence of 'change fatigue', may block change. Pre-intervention exploration may help identify any potential barriers to embedding recovery in the organizational culture. © 2016 John Wiley & Sons Ltd.

  9. Generalist genes and learning disabilities.

    Plomin, Robert; Kovas, Yulia

    2005-07-01

    The authors reviewed recent quantitative genetic research on learning disabilities that led to the conclusion that genetic diagnoses differ from traditional diagnoses in that the effects of relevant genes are largely general rather than specific. This research suggests that most genes associated with common learning disabilities--language impairment, reading disability, and mathematics disability--are generalists in 3 ways. First, genes that affect common learning disabilities are largely the same genes responsible for normal variation in learning abilities. Second, genes that affect any aspect of a learning disability affect other aspects of the disability. Third, genes that affect one learning disability are also likely to affect other learning disabilities. These quantitative genetic findings have far-reaching implications for molecular genetics and neuroscience as well as psychology. Copyright 2005 APA, all rights reserved.

    2014-05-01

    Full Text Available Background Recently, at a time of frequent changes in the economic and socio-economic circumstances, knowledge acquired in the course of formal education is insufficient. Especially, the education system is still criticized for a lack of flexibility and strong resistance to change. Therefore, regular participation in various forms of training is required. Employee education and training are becoming an optimal answer to complex business challenges. The aim of this study was to determine which personality traits are responsible for the strength of motivation to undertake vocational training and other educational forms. Participants and procedure The study included 104 staff members of Polish companies (60 women and 44 men. The study used Cattell’s 16 PF Questionnaire and the scales of readiness to undertake training and further education as a measure of the strength of motivation (Kawecka, Łaguna & Tabor, 2010. Results The study showed that openness to change and tension (primary traits had the greatest impact on the intention and planning to take vocational training. Additionally, the intention and planning to take vocational training were found to be associated with mindedness, independence, self-control, and anxiety (secondary traits. Such traits as rule-consciousness [G], social-boldness [H], abstractedness [M], and apprehension [O] (primary traits, were important in some aspects, which could constitute a background for further research and discussion of the results. Conclusions The obtained results lead to the conclusion that some of the individual differences in personality determine the motivation to undertake vocational training.

    The range of hosts that parasites can infect is a key determinant of the emergence and spread of disease. Yet, the impact of host range variation on the evolution of parasite genomes remains unknown. Here, we show that codon optimization underlies genome adaptation in broad host range parasites. We found that the longer proteins encoded by broad host range fungi likely increase natural selection on codon optimization in these species. Accordingly, codon optimization correlates with host range across the fungal kingdom. At the species level, biased patterns of synonymous substitutions underpin increased codon optimization in a generalist but not a specialist fungal pathogen. Virulence genes were consistently enriched in highly codon-optimized genes of generalist but not specialist species. We conclude that codon optimization is related to the capacity of parasites to colonize multiple hosts. Our results link genome evolution and translational regulation to the long-term persistence of generalist parasitism.

    Why generalist and specialist species coexist in nature is a question that has interested evolutionary biologists for a long time. While the coexistence of specialists and generalists exploiting resources on a single ecological dimension has been theoretically and empirically explored, biological systems with multiple resource dimensions (e.g. trophic, ecological) are less well understood. Yet, such systems may provide an alternative to the classical theory of stable evolutionary coexistence of generalist and specialist species on a single resource dimension. We explore such systems and the potential trade-offs between different resource dimensions in clownfishes. All species of this iconic clade are obligate mutualists with sea anemones yet show interspecific variation in anemone host specificity. Moreover, clownfishes developed variable environmental specialization across their distribution. In this study, we test for the existence of a relationship between host-specificity (number of anemones associated with a clownfish species) and environmental-specificity (expressed as the size of the ecological niche breadth across climatic gradients). We find a negative correlation between host range and environmental specificities in temperature, salinity and pH, probably indicating a trade-off between both types of specialization forcing species to specialize only in a single direction. Trade-offs in a multi-dimensional resource space could be a novel way of explaining the coexistence of generalist and specialists. © 2014 The Author(s) Published by the Royal Society.

  19. Measuring hospital medical staff organizational structure.

    Science.gov (United States)

    Shortell, S M; Getzen, T E

    1979-01-01

    Based on organization theory and the work of Roemer and Friedman, seven dimensions of hospital medical staff organization structure are proposed and examined. The data are based on a 1973 nationwide survey of hospital medical staffs conducted by the American Hospital Association. Factor analysis yielded six relatively independent dimensions supporting a multidimensional view of medical staff organization structure. The six dimensions include 1) Resource Capability, 2) Generalist Physician Contractual Orientation, 3) Communication/Control, 4) Local Staff Orientation, 5) Participation in Decision Making, and 6) Hospital-Based Physician Contractual Orientation. It is suggested that these dimensions can be used to develop an empirical typology of hospital medical staff organization structure and to investigate the relationship between medical staff organization and public policy issues related to cost containment and quality assurance.

  20. Distributions of Bacterial Generalists among the Guts of Birds ...

    Science.gov (United States)

    Complex distributions of bacterial taxa within diverse animal microbiomes have inspired ecological and biogeographical approaches to revealing the functions of taxa that may be most important for host health. Of particular interest are bacteria that find many diverse habitats suitable for growth and remain competitive amongst finely-tuned host specialists. While previous work has focused on identifying these specialists, here our aims were to 1) identify generalist taxa, 2) identify taxonomic clades with enriched generalist diversity, and 3) describe the distribution of the largest generalist groups among hosts. We analyzed existing bacterial rRNA tag-sequencing data (v6) available on VAMPs (vamps.mbl.edu) from the microbiomes of 12 host species (106 samples total) spanning birds, mammals, and fish for generalist taxa using the CLAM test. OTUs with approximately equal abundance and a minimum of 10 reads in two hosts were classified as generalists. Generalist OTUs (n=2,982) were found in all hosts tested. Bacterial families Alcaligenaceae and Burkholderiaceae were significantly enriched with generalists OTUs compared to other families. Bacterial families such as Bacteroidaceae and Lachnospiraceae significantly lacked generalists OTUs compared to other families. Enterobacteriaceae, Peptostreptococcaceae, and Erysipelotrichaceae more so than other bacterial families were widely distributed and abundant in birds, mammals, and fish suggesting that these taxa mainta

  3. Who should be undertaking population-based surveys in humanitarian emergencies?

    Directory of Open Access Journals (Sweden)

    Spiegel Paul B

    2007-06-01

    Full Text Available Abstract Background Timely and accurate data are necessary to prioritise and effectively respond to humanitarian emergencies. 30-by-30 cluster surveys are commonly used in humanitarian emergencies because of their purported simplicity and reasonable validity and precision. Agencies have increasingly used 30-by-30 cluster surveys to undertake measurements beyond immunisation coverage and nutritional status. Methodological errors in cluster surveys have likely occurred for decades in humanitarian emergencies, often with unknown or unevaluated consequences. Discussion Most surveys in humanitarian emergencies are done by non-governmental organisations (NGOs. Some undertake good quality surveys while others have an already overburdened staff with limited epidemiological skills. Manuals explaining cluster survey methodology are available and in use. However, it is debatable as to whether using standardised, 'cookbook' survey methodologies are appropriate. Coordination of surveys is often lacking. If a coordinating body is established, as recommended, it is questionable whether it should have sole authority to release surveys due to insufficient independence. Donors should provide sufficient funding for personnel, training, and survey implementation, and not solely for direct programme implementation. Summary A dedicated corps of trained epidemiologists needs to be identified and made available to undertake surveys in humanitarian emergencies. NGOs in the field may need to form an alliance with certain specialised agencies or pool technically capable personnel. If NGOs continue to do surveys by themselves, a simple training manual with sample survey questionnaires, methodology, standardised files for data entry and analysis, and manual for interpretation should be developed and modified locally for each situation. At the beginning of an emergency, a central coordinating body should be established that has sufficient authority to set survey standards

  4. Staff rotation: implications for occupational therapy.

    1995-10-01

    Occupational therapy departments of tertiary care hospitals can provide staff with opportunities to gain diverse clinical experience if they rotate through the various services such as surgery, medicine, geriatrics, plastic surgery and orthopaedics. The system of rotation offers both advantages and disadvantages for the staff and the institution. The Royal Victoria Hospital in Montreal, a large university teaching hospital, had traditionally offered staff the opportunity to rotate. Changes in staffing and their needs however, resulted in rotation becoming an important issue within the department. This article presents the pros and the cons of rotation and non-rotation systems as identified by therapists and administrators across Canada. Staff rotation was found to have an effect on job satisfaction and a therapist's career orientation. Given these findings, administrators may want to reconsider the role of the generalist and specialist in their facilities.

    We develop a novel statistical approach for classifying generalists and specialists in two distinct habitats. Using a multinomial model based on estimated species relative abundance in two habitats, our method minimizes bias due to differences in sampling intensities between two habitat types...... as well as bias due to insufficient sampling within each habitat. The method permits a robust statistical classification of habitat specialists and generalists, without excluding rare species a priori. Based on a user-defined specialization threshold, the model classifies species into one of four groups......: (1) generalist; (2) habitat A specialist; (3) habitat B specialist; and (4) too rare to classify with confidence. We illustrate our multinomial classification method using two contrasting data sets: (1) bird abundance in woodland and heath habitats in southeastern Australia and (2) tree abundance...

    2015-01-01

    It is widely assumed that floral diversification occurs by adaptive shifts between pollination niches. In contrast to specialized flowers, identifying pollination niches of generalist flowers is a challenge. Consequently, how generalist pollination niches evolve is largely unknown. We apply tools from network theory and comparative methods to investigate the evolution of pollination niches among generalist species belonging to the genus Erysimum. These species have similar flowers. We found that the studied species may be grouped in several multidimensional niches separated not by a shift of pollinators, but instead by quantitative variation in the relative abundance of pollinator functional groups. These pollination niches did not vary in generalization degree; we did not find any evolutionary trend toward specialization within the studied clade. Furthermore, the evolution of pollination niche fitted to a Brownian motion model without phylogenetic signal, and was characterized by frequent events of niche convergences and divergences. We presume that the evolution of Erysimum pollination niches has occurred mostly by recurrent shifts between slightly different generalized pollinator assemblages varying spatially as a mosaic and without any change in specialization degree. Most changes in pollination niches do not prompt floral divergence, a reason why adaptation to pollinators is uncommon in generalist plants. © 2014 The Authors.

  14. Macrophytes shape trophic niche variation among generalist fishes.

    Directory of Open Access Journals (Sweden)

    Ivana Vejříková

    Full Text Available Generalist species commonly have a fundamental role in ecosystems as they can integrate spatially distinct habitats and food-web compartments, as well as control the composition, abundance and behavior of organisms at different trophic levels. Generalist populations typically consist of specialized individuals, but the potential for and hence degree of individual niche variation can be largely determined by habitat complexity. We compared individual niche variation within three generalist fishes between two comparable lakes in the Czech Republic differing in macrophyte cover, i.e. macrophyte-rich Milada and macrophyte-poor Most. We tested the hypothesis that large individual niche variation among generalist fishes is facilitated by the presence of macrophytes, which provides niches and predation shelter for fish and their prey items. Based on results from stable nitrogen (δ15N and carbon (δ13C isotopic mixing models, perch (Perca fluviatilis L. and rudd (Scardinius erythrophthalmus (L. showed larger individual variation (i.e., variance in trophic position in Milada as compared to Most, whereas no significant between-lake differences were observed for roach (Rutilus rutilus (L.. Contrary to our hypothesis, all the three species showed significantly lower individual variation in the relative reliance on littoral food resources in Milada than in Most. Rudd relied significantly more whereas perch and roach relied less on littoral food resources in Milada than in Most, likely due to prevalent herbivory by rudd and prevalent zooplanktivory by perch and roach in the macrophyte-rich Milada as compared to macrophyte-poor Most. Our study demonstrates how the succession of macrophyte vegetation, via its effects on the physical and biological complexity of the littoral zone and on the availability of small prey fish and zooplankton, can strongly influence individual niche variation among generalist fishes with different ontogenetic trajectories, and hence

    Full Text Available Prey choice is often evaluated at the species or population level. Here, we analyzed the diet of octopuses of different populations with the aim to assess the importance of individual feeding habits as a factor affecting prey choice. Two methods were used, an assessment of the extent to which an individual octopus made choices of species representative of those population (PSi and IS and 25% cutoff values for number of choices and percentage intake of individual on their prey. In one population of Octopus cf vulgaris in Bermuda individuals were generalist by IS=0.77, but most chose many prey of the same species, and were specialists on it by >75% intake. Another population had a wider prey selection, still generalist with PSi=0.66, but two individuals specialized by choices. In Bonaire, there was a wide range of prey species chosen, and the population was specialists by IS= 0.42. Individual choices revealed seven specialists and four generalists. A population of Octopus cyanea in Hawaii all had similar choices of crustaceans, so the population was generalist by IS with 0.74. But by individual choices, three were considered a specialist. A population of Enteroctopus dofleini from Puget Sound had a wide range of preferences, in which seven were also specialists, IS=0.53. By individual choices, thirteen were also specialists. Given the octopus specialty of learning during foraging, we hypothesize that both localized prey availability and individual personality differences could influence the exploration for prey and this translates into different prey choices across individuals and populations showed in this study [Current Zoology 58 (4: 597-603, 2012].

    Full Text Available Determining bee and plant interactions has an important role on understanding general biology of bee species as well as the potential pollinating relationship between them. Bee surveys have been conducted in Brazil since the end of the 1960s. Most of them applied standardized methods and had identified the plant species where the bees were collected. To analyze the most generalist bees on Brazilian surveys, we built a matrix of bee-plant interactions. We estimated the most generalist bees determining the three bee species of each surveyed locality that presented the highest number of interactions. We found 47 localities and 39 species of bees. Most of them belong to Apidae (31 species and Halictidae (6 families and to Meliponini (14 and Xylocopini (6 tribes. However, most of the surveys presented Apis mellifera and/or Trigona spinipes as the most generalist species. Apis mellifera is an exotic bee species and Trigona spinipes, a native species, is also widespread and presents broad diet breath and high number of individuals per colony.

    Planning games have been found satisfactory in many field in political and economic life. In particular the more convenient access to electronic calculators has made a contrinution to their wider use. It is therefore surprising that the first planning game which has become known for the electricity supply industry was first published in the year 1975. This is the planning game for the Bernischen Kraftwerke AG, which is based on a simplified model of a small electricity supply undertaking (EVU). This planning game was adapted in the RWE to the conditions in larger EVU and a few additional model components were added. Besides the general points of view on planning games for EVU the author deals with the extended planning game which is termed in the article PEW. (orig.) [de

  7. Weather conditions drive dynamic habitat selection in a generalist predator.

    Directory of Open Access Journals (Sweden)

    Peter Sunde

    Full Text Available Despite the dynamic nature of habitat selection, temporal variation as arising from factors such as weather are rarely quantified in species-habitat relationships. We analysed habitat use and selection (use/availability of foraging, radio-tagged little owls (Athene noctua, a nocturnal, year-round resident generalist predator, to see how this varied as a function of weather, season and availability. Use of the two most frequently used land cover types, gardens/buildings and cultivated fields varied more than 3-fold as a simple function of season and weather through linear effects of wind and quadratic effects of temperature. Even when controlling for the temporal context, both land cover types were used more evenly than predicted from variation in availability (functional response in habitat selection. Use of two other land cover categories (pastures and moist areas increased linearly with temperature and was proportional to their availability. The study shows that habitat selection by generalist foragers may be highly dependent on temporal variables such as weather, probably because such foragers switch between weather dependent feeding opportunities offered by different land cover types. An opportunistic foraging strategy in a landscape with erratically appearing feeding opportunities in different land cover types, may possibly also explain decreasing selection of the two most frequently used land cover types with increasing availability.

  8. Applying research to practice: generalist and specialist (visual ergonomics) consultancy.

    Long, Jennifer; Long, Airdrie

    2012-01-01

    Ergonomics is a holistic discipline encompassing a wide range of special interest groups. The role of an ergonomics consultant is to provide integrated solutions to improve comfort, safety and productivity. In Australia, there are two types of consultants--generalists and specialists. Both have training in ergonomics but specialist knowledge may be the result of previous education or work experience. This paper presents three projects illustrating generalist and specialist (visual ergonomics) consultancy: development of a vision screening protocol, solving visual discomfort in an office environment and solving postural discomfort in heavy industry. These case studies demonstrate how multiple ergonomics consultants may work together to solve ergonomics problems. It also describes some of the challenges for consultants, for those engaging their services and for the ergonomics profession, e.g. recognizing the boundaries of expertise, sharing information with business competitors, the costs-benefits of engaging multiple consultants and the risk of fragmentation of ergonomics knowledge and solutions. Since ergonomics problems are often multifaceted, ergonomics consultants should have a solid grounding in all domains of ergonomics, even if they ultimately only practice in one specialty or domain. This will benefit the profession and ensure that ergonomics remains a holistic discipline.

  9. Coexisting generalist herbivores occupy unique nutritional feeding niches

    Behmer, Spencer T.; Joern, Anthony

    2008-01-01

    A mainstay of ecological theory and practice is that coexisting species use different resources, leading to the local development of biodiversity. However, a problem arises for understanding coexistence of multiple species if they share critical resources too generally. Here, we employ an experimental framework grounded in nutritional physiology to show that closely related, cooccurring and generalist-feeding herbivores (seven grasshopper species in the genus Melanoplus; Orthoptera: Acrididae) eat protein and carbohydrate in different absolute amounts and ratios even if they eat the same plant taxa. The existence of species-specific nutritional niches provides a cryptic mechanism that helps explain how generalist herbivores with broadly overlapping diets might coexist. We also show that performance by grasshoppers allowed to mix their diets and thus regulate their protein–carbohydrate intake matched optimal performance peaks generated from no-choice treatments. These results indicate the active nature of diet selection to achieve balanced diets and provide buffering capacity in the face of variable food quality. Our empirical findings and experimental approach can be extended to generate and test predictions concerning the intensity of biotic interactions between species, the relative abundance of species, yearly fluctuations in population size, and the nature of interactions with natural enemies in tritrophic niche space.

    2010-01-01

    People living in rural and remote areas have been found to suffer higher rates of mental illness and psychological distress than their urban counterparts. However, rural and remote Australians also suffer from a lack of specialist mental health services. Mental health consumers are concerned about the lack of access to specialist mental health care and report poor service quality and stigmatizing staff attitudes when presenting with mental health emergencies at acute care facilities. Standards for the Mental Health Workforce released in 2002 promote respect for the individual, their family and carers; best practice in the assessment, early detection and management of acute illness; promotion of mental health and safety; and the prevention of relapse. These standards are for generalists providing care to mentally ill patients; their family and carers in the acute care setting; as well as specialist mental health professionals. Up-skilling generalists in rural and remote areas to respectfully and effectively manage mental health emergency care is a priority. A short course, 'Managing Mental Health Emergencies' was developed by the Australian Rural Nurses and Midwives in 2002. Almost 750 participants had completed the course at the time of the evaluation. The objectives of the course were to: develop an increased knowledge of mental health presentations and gain confidence in managing and assessing mental health clients; gain an understanding of the referral processes in the local environment; gain an insight into the impact of mental health emergencies on individuals, their family and carers; and identify strategies to minimise the impact of managing mental health emergencies on the healthcare team. The model of training matched what is known to be best practice in rural and remote health practitioner development in emergency care, being local, interdisciplinary, and engaging local expert service providers while being overseen by a national steering committee.

    Full Text Available Economists commonly specialize in some limited parts of the general field. This is a necessity, due to the complexity of the different issues, the amount of literature available on each of them and the possibility of recourse to different analytical or statistical tools. However, specialization has its drawbacks. Quite often, specialists in the fields of, for instance, labour economics or industrial organization, utilize tools such as the aggregate production function or Marshallian U-shaped cost curves for the firm and the industry; tools which any specialist in abstract theory knows to have been proved faulty. Again, quite often econometric exercises rely on implicit, forgotten assumptions which if duly recognized would deprive the results of any meaning with regard to the interpretation of real world events. The risks of field specialization are commonly countered by the existence of generalist journals, such as the present one.

    Full Text Available Although macro issues are integral to social work, students continue to struggle with the acquisition of knowledge and skills pertaining to larger systems. Educators have developed innovative methods to integrate learning across systems of various sizes however it appears an imbalance persists. This challenge is supported by baccalaureate student responses to a social work program evaluation. Four years of data from 295 undergraduate students revealed that they felt less prepared to practice with larger, macro systems. Changes in curriculum to reflect collaboration and holism, and more research are needed to adequately provide macro learning and macro practice opportunities within the generalist model and in the context of the current socio-economic-political environment.

    Background Treatment of allergic rhinitis (AR) consistent with consensus guidelines is reported to result in better patient outcomes. However, physicians may manage patients independently of guidelines. Asian data on physician perspectives regarding AR diagnosis and management is limited. Objective The study objective is to assess attitudes and practices on AR of Filipino specialists and generalists. Methods A cross sectional survey of 100 specialists and 100 generalists was conducted from November 2014 to January 2015. A previously validated and pilot tested questionnaire was administered via structured face to face interviews. Results Specialists reported greater adequate knowledge of AR (specialists, 58%; generalists, 39%) and adherence to guidelines (specialists, 84%; generalists, 54%). Diagnostic tests were not routinely used (specialists, 81%; generalists, 92%). Monotherapy, specifically antihistamines, was preferred for mild AR. For moderate-severe AR, preference for monotherapy versus combination therapy (specialists, 49% vs. 51%; generalists, 44% vs. 56%) was similar. Both groups preferred intranasal corticosteroid spray (INCS) for monotherapy and antileukotrienes, antihistamines, INCS for combination therapy. For adjuvant therapy, specialists (82%) preferred nasal irrigation/douche. Primary consideration for choice of therapy was efficacy. Cost was the perceived reason for patients' noncompliance with treatment. Conclusion Despite differences in awareness of and adherence to guidelines, prescribing patterns on management of mild and moderate-severe AR are similar among Filipino specialists and generalists. This can be attributed to a shared perception of efficacy and cost as drivers for therapeutic choices. PMID:26539402

    Full Text Available Abstract Background In most states, mental illness costs are an increasing share of Medicaid expenditures. Specialized depression care managers (CM have consistently demonstrated improvements in patient outcomes relative to usual primary care (UC, but are costly and may not be fully utilized in smaller practices. A generalist care manager (GCM could manage multiple chronic conditions and be more accepted and cost-effective than the specialist depression CM. We designed a pilot program to demonstrate the feasibility of training/deploying GCMs into primary care settings. Methods We randomized depressed adult Medicaid patients in 2 primary care practices in Western North Carolina to a GCM intervention or to UC. GCMs, already providing services in diabetes and asthma in both study arms, were further trained to provide depression services including self-management, decision support, use of information systems, and care management. The following data were analyzed: baseline, 3- and 6-month Patient Health Questionnaire (PHQ9 scores; baseline and 6-month Short Form (SF 12 scores; Medicaid claims data; questionnaire on patients' perceptions of treatment; GCM case notes; physician and office staff time study; and physician and office staff focus group discussions. Results Forty-five patients were enrolled, the majority with preexisting depression. Both groups improved; the GCM group did not demonstrate better clinical and functional outcomes than the UC group. Patients in the GCM group were more likely to have prescriptions of correct dosing by chart data. GCMs most often addressed comorbid conditions (36%, then social issues (27% and appointment reminders (14%. GCMs recorded an average of 46 interactions per patient in the GCM arm. Focus group data demonstrated that physicians valued using GCMs. A time study documented that staff required no more time interacting with GCMs, whereas physicians spent an average of 4 minutes more per week. Conclusion GCMs

  20. Discovering potential sources of emerging pathogens: South America is a reservoir of generalist avian blood parasites.

    Moens, Michaël A J; Pérez-Tris, Javier

    2016-01-01

    Generalist pathogens are capable of infecting a wide range of host species, and may pose serious disease emergence threats if accidentally moved outside their native areas. To date little effort has been devoted to identifying geographic areas that may act as reservoirs of generalist pathogens. According to current theory, where host diversity is high, parasite specialisation in one host species may be penalised by reduced host availability, while generalist parasites may benefit from the exploitation of various host species. Therefore natural selection could favor generalist parasites where host diversity is high. Here we explored if, in a highly diverse bird community in Ecuador, a generalist strategy is promoted among local Haemoproteus and Plasmodium blood-borne parasites compared with similar parasite communities throughout the world. We reconstructed the phylogenetic relationships of every parasite lineage in order to understand the evolution of host specificity in this megadiverse area. We found high levels of host generalisation for both parasite genera, and the mean host range of the Haemoproteus community in Ecuador was significantly higher than other parasite communities in other areas outside the Neotropics. Generalist Haemoproteus parasites in this bird community had diverse phylogenetic ancestry, were closely related to specialist parasites and were apparently endemic to the Amazon, showing that different parasites have independently evolved into host generalists in this region. Finally we show that Haemoproteus communities in Ecuador and South America are more generalist than in temperate areas, making this continent a hotspot of generalist Haemoproteus parasites for wild birds.

  3. Explaining postnatal growth plasticity in a generalist brood parasite

    Remeš, Vladimír

    2010-03-01

    Selection of a particular host has clear consequences for the performance of avian brood parasites. Experimental studies showed that growth rate and fledging mass of brood parasites varied between host species independently of the original host species. Finding correlates of this phenotypic plasticity in growth is important for assessing adaptiveness and potential fitness consequences of host choice. Here, I analyzed the effects of several host characteristics on growth rate and fledging mass of the young of brown-headed cowbird ( Molothrus ater), a generalist, non-evicting brood parasite. Cowbird chicks grew better in fast-developing host species and reached higher fledging mass in large hosts with fast postnatal development. A potential proximate mechanism linking fast growth and high fledging mass of cowbird with fast host development is superior food supply in fast-developing foster species. So far, we know very little about the consequences of the great plasticity in cowbird growth for later performance of the adult parasite. Thus, cowbird species could become interesting model systems for investigating the role of plasticity and optimization in the evolution of growth rate in birds.

  4. Faba bean forisomes can function in defence against generalist aphids.

    Science.gov (United States)

    Medina-Ortega, Karla J; Walker, Gregory P

    2015-06-01

    Phloem sieve elements have shut-off mechanisms that prevent loss of nutrient-rich phloem sap when the phloem is damaged. Some phloem proteins such as the proteins that form forisomes in legume sieve elements are one such mechanism and in response to damage, they instantly form occlusions that stop the flow of sap. It has long been hypothesized that one function of phloem proteins is defence against phloem sap-feeding insects such as aphids. This study provides the first experimental evidence that aphid feeding can induce phloem protein occlusion and that the aphid-induced occlusions inhibit phloem sap ingestion. The great majority of phloem penetrations in Vicia faba by the generalist aphids Myzus persicae and Macrosiphum euphorbiae triggered forisome occlusion and the aphids eventually withdrew their stylets without ingesting phloem sap. This contrasts starkly with a previous study on the legume-specialist aphid, Acyrthosiphon pisum, where penetration of faba bean sieve elements did not trigger forisome occlusion and the aphids readily ingested phloem sap. Next, forisome occlusion was demonstrated to be the cause of failed phloem ingestion attempts by M. persicae: when occlusion was inhibited by the calcium channel blocker lanthanum, M. persicae readily ingested faba bean phloem sap. © 2014 John Wiley & Sons Ltd.

  5. River Cetaceans and Habitat Change: Generalist Resilience or Specialist Vulnerability?

    Directory of Open Access Journals (Sweden)

    Brian D. Smith

    2012-01-01

    Full Text Available River dolphins are among the world’s most threatened mammals, and indeed the baiji (Lipotes vexillifer, a species endemic to China's Yangtze River, is likely extinct. Exploitation for products such as meat, oil, and skins has been a lesser feature in the population histories of river dolphins compared to most large mammals. Habitat factors are therefore of particular interest and concern. In this paper we attempt to describe the population-level responses of river dolphins to habitat transformation. We find circumstantial but compelling evidence supporting the view that, at a local scale, river dolphins are opportunists (generalists capable of adapting to a wide range of habitat conditions while, at a river basin scale, they are more appropriately viewed as vulnerable specialists. The same evidence implies that the distributional responses of river dolphins to basinwide ecological change can be informative about their extinction risk, while their local behaviour patterns may provide important insights about critical ecological attributes. Empirical studies are needed on the ecology of river cetaceans, both to inform conservation efforts on behalf of these threatened animals and to help address broader concerns related to biodiversity conservation and the sustainability of human use in several of the world's largest river systems.

  6. Generalist versus specialist pollination systems in 26 Oenothera (Onagraceae

    Directory of Open Access Journals (Sweden)

    Kyra Neipp Krakos

    2014-09-01

    Full Text Available Although generalized and specialized plants are often discussed as alternative states, the biological reality may better be viewed as a continuum. However, estimations of pollinator specificity have been confounded in some studies by the assumption that all floral visitors are pollinators. Failure to account for pollen load can lead to inaccurate conclusions regarding the number of pollinators with which a species actually interacts. The aim of this study was to clarify the distribution of pollination-system specialization within one clade, using a more rigorous assessment of pollen flow. The genus Oenothera has long been used as a model system for studying reproductive biology, and it provides a diversity of pollination systems and a wealth of historical data. Both floral visitation rate and pollen-load analysis of sampled pollinators, combined into a metric of pollen flow, were used to quantify the pollination systems of 26 Oenothera taxa. Metric of pollinator specialization were calculated as functions of both total pollinator taxa, and as pollinator functional groups. We found that for Oenothera, the number of floral visitors highly overestimates the number of pollinators, and is inadequate for determining or predicting pollination system specialization. We found that that pollination systems were distributed on a gradient from generalized to specialized, with more pollinator-specialized plant taxa, especially when estimated using pollinator functional groups. These results are in conflict with previous studies that depict most plant species as generalists, and this finding may be related to how prior studies have estimated specialization.

    Typically, ground staff scheduling is centrally planned for each terminal in an airport. The advantage of this is that the staff is efficiently utilized, but a disadvantage is that staff spends considerable time walking between stands. In this paper a decentralized approach for ground staff...... scheduling is investigated. The airport terminal is divided into zones, where each zone consists of a set of stands geographically next to each other. Staff is assigned to work in only one zone and the staff scheduling is planned decentralized for each zone. The advantage of this approach is that the staff...... work in a smaller area of the terminal and thus spends less time walking between stands. When planning decentralized the allocation of stands to flights influences the staff scheduling since the workload in a zone depends on which flights are allocated to stands in the zone. Hence solving the problem...

    Joint Vision 2020 highlights that achievement of `full spectrum dominance rests upon information superiority' and that information capabilities are changing rapidly. Similarly the Eight Great Technologies and McKinsey Global Institute have highlighted the criticality of `Big Data' technologies. But most `Big Data' technologies are predicated on the availability of high quality/bandwidth distributed information Infrastructure and service rich systems, and much of the technology is designed for use by highly trained data scientists. In deployed military operations the context is radically different; many analysts are generalists as opposed to highly trained data scientists, and the information infrastructure is frequently significantly smaller, sparse and brittle but nevertheless complex. Further operations are highly dynamic, temporally challenging, and in an unfamiliar sociocultural environment. As Joint Vision 2020 states `the need to shape ambiguous situations at the low end of the range of operations will present special challenges'. This paper outlines the S&T challenges associated with adapting `Big Data' technologies to build a distributed analytic capability for the deployed operations. In particular we will discuss issues associated with: a) The adoption of data analytic platforms and the need for adaption to a distributed coalition environment and tactical information infrastructures; b) The Volume, Velocity, Variety, Veracity, Viscosity and Value of information and information processing, storage and distribution capabilities; c) The nature of the situations to be understood and the resulting impact on abstract representations and synergistic human-machine teams; d) The role of the human in collaboratively extracting understanding from information and directing the information system.

  12. Two invasive acacia species secure generalist pollinators in invaded communities

    Exotic entomophilous plants need to establish effective pollinator interactions in order to succeed after being introduced into a new community, particularly if they are obligatory outbreeders. By establishing these novel interactions in the new non-native range, invasive plants are hypothesised to drive changes in the composition and functioning of the native pollinator community, with potential impacts on the pollination biology of native co-flowering plants. We used two different sites in Portugal, each invaded by a different acacia species, to assess whether two native Australian trees, Acacia dealbata and Acacia longifolia, were able to recruit pollinators in Portugal, and whether the pollinator community visiting acacia trees differed from the pollinator communities interacting with native co-flowering plants. Our results indicate that in the invaded range of Portugal both acacia species were able to establish novel mutualistic interactions, predominantly with generalist pollinators. For each of the two studied sites, only two other co-occurring native plant species presented partially overlapping phenologies. We observed significant differences in pollinator richness and visitation rates among native and non-native plant species, although the study of β diversity indicated that only the native plant Lithodora fruticosa presented a differentiated set of pollinator species. Acacias experienced a large number of visits by numerous pollinator species, but massive acacia flowering resulted in flower visitation rates frequently lower than those of the native co-flowering species. We conclude that the establishment of mutualisms in Portugal likely contributes to the effective and profuse production of acacia seeds in Portugal. Despite the massive flowering of A. dealbata and A. longifolia, native plant species attained similar or higher visitation rates than acacias.

  14. Forty project management strategies for the medical practice staff.

    Science.gov (United States)

    Hills, Laura Sachs

    2010-01-01

    Most every medical practice will embark at one time or another on a large and complex new project. The practice may, for instance, undertake a project in office construction or renovation, practice expansion, new technology, or a new large-scale event. The medical practice staff may find itself creating the project plan, overseeing its execution, and working through the plan day to day until its completion. In short, the staff may find itself responsible for project management. This article contains 40 specific, easy-to-implement project management strategies medical practice employees can use to manage both the large and small projects they undertake on behalf of the practice. It suggests effective project management strategies the staff can use before the onset of a new project as well as strategies to help define the project, to deliver the project, and to close and review the project. This article also describes five reasons medical practices often fail at project management and suggests more effective approaches that will ensure that the projects the medical practice undertakes are completed well, on time, and within budget.

    Invasive alien plants are likely to be released from specialist herbivores and at the same time encounter biotic resistance from resident generalist herbivores in their new ranges. The Shifting Defense hypothesis predicts that this will result in evolution of decreased defense against specialist herbivores and increased defense against generalist herbivores. To test this, we performed a comprehensive meta-analysis of 61 common garden studies that provide data on resistance and/or tolerance for both introduced and native populations of 32 invasive plant species. We demonstrate that introduced populations, relative to native populations, decreased their resistance against specialists, and increased their resistance against generalists. These differences were significant when resistance was measured in terms of damage caused by the herbivore, but not in terms of performance of the herbivore. Furthermore, we found the first evidence that the magnitude of resistance differences between introduced and native populations depended significantly on herbivore origin (i.e., whether the test herbivore was collected from the native or non-native range of the invasive plant). Finally, tolerance to generalists was found to be higher in introduced populations, while neither tolerance to specialists nor that to simulated herbivory differed between introduced and native plant populations. We conclude that enemy release from specialist herbivores and biotic resistance from generalist herbivores have contrasting effects on resistance evolution in invasive plants. Our results thus provide strong support for the Shifting Defense hypothesis. © 2018 by the Ecological Society of America.

    2012-05-01

    The care that most people receive at the end of their lives is provided not by specialist palliative care professionals but by generalists such as GPs, district nurses and others who have not undertaken specialist training in palliative care. A key focus of recent UK policy is improving partnership working across the spectrum of palliative care provision. However there is little evidence to suggest factors which support collaborative working between specialist and generalist palliative care providers. To explore factors that support partnership working between specialist and generalist palliative care providers. Systematic review. A systematic review of studies relating to partnership working between specialist and generalist palliative care providers was undertaken. Six electronic databases were searched for papers published up until January 2011. Of the 159 articles initially identified, 22 papers met the criteria for inclusion. Factors supporting good partnership working included: good communication between providers; clear definition of roles and responsibilities; opportunities for shared learning and education; appropriate and timely access to specialist palliative care services; and coordinated care. Multiple examples exist of good partnership working between specialist and generalist providers; however, there is little consistency regarding how models of collaborative working are developed, and which models are most effective. Little is known about the direct impact of collaborative working on patient outcomes. Further research is required to gain the direct perspectives of health professionals and patients regarding collaborative working in palliative care, and to develop appropriate and cost-effective models for partnership working.

    Full Text Available Objective:To compare the residency selection choices of students who experienced courses resulting from generalist physician initiatives to choices made by students prior to the implementation of those courses and to describe the characteristics of students selecting primary care residencies. Background:In the fall of 1994 a first year Community Continuity Experience course was initiated and in the summer of 1995 a third year Multidisciplinary Ambulatory Clerkship was begun at the University of Texas Medical Branch in Galveston. These courses were inserted into the curriculum to enhance and promote primary care education. Design/Methods:We examined the residency selections of cohorts of graduating medical students before (1992-1996 and after (1997-1999 the implementation of the primary care courses. Survey information on career preferences at matriculation and in the fourth year of medical school were available for students graduating after the programs began. We compared the career preferences and characteristics of those students who selected a primary care residency to those who did not. Results:Prior to the implementation of the programs, 45%(425/950 of students graduating selected primary care residencies compared to 45% (210/465 of students participating in the programs (p=0.88. At matriculation, 45% of students had listed a primary care discipline as their first career choice. Among the students who had indicated this degree of primary care interest 61% ended up matching in a primary care discipline. At year 4, 31% of students indicated a primary care discipline as their first career choice and 92% of these students matched to a primary care residency. By univariate analysis, minority students (53% were more likely to select a primary care residency than non-minority students (40%; students in the two lowest grade point average quartiles (55% and 50% selected primary care residencies compared to 37% and 38% of students in the top 2

    Full Text Available This study concerns the general rules on competition between undertakings in the EU. The author paid attention primarly to matters on the prohibition of agreements that aim to distort or impair competition on the internal market. Moreover, he examined in detail the matter concerning the regulation and interdiction of the abuse of a dominant position. The work also reviews doctrinal opinions, as well as the jurisprudential solutions in the area. The author’s concern to summarize and develop the conditions for the implementation of each of the two legal mechanisms is worth noting: the prohibition of agreements between undertakings and the abuse of a dominant position. The essential considerations taken into account by the Court of Justice of the European Union in settling a case whose subject consisted of assessing the manner in which an undertaking reflected on competition on the internal market were selected at the end of the work.

    Selection exerted by herbivores is a major force driving the evolution of plant defensive characters such as leaf trichomes or secondary metabolites. However, plant defense expression is highly variable among populations and identifying the sources of this variation remains a major challenge. Plant populations are often distributed across broad geographic ranges and are exposed to different herbivore communities, ranging from generalists (that feed on diverse plant species) to specialists (that feed on a restricted group of plants). We studied eight populations of the plant Datura stramonium usually eaten by specialist or generalist herbivores, in order to examine whether the pattern of phenotypic selection on secondary compounds (atropine and scopolamine) and a physical defense (trichome density) can explain geographic variation in these traits. Following co-evolutionary theory, we evaluated whether a more derived alkaloid (scopolamine) confers higher fitness benefits than its precursor (atropine), and whether this effect differs between specialist and generalist herbivores. Our results showed consistent directional selection in almost all populations and herbivores to reduce the concentration of atropine. The most derived alkaloid (scopolamine) was favored in only one of the populations, which is dominated by a generalist herbivore. In general, the patterns of selection support the existence of a selection mosaic and accounts for the positive correlation observed between atropine concentration and plant damage by herbivores recorded in previous studies.

    2015-09-01

    Epidemiological rate parameters of host generalist parasites are difficult to estimate, especially in cases where variation in parasite performance can be attributed to host species. Such cases are likely common for generalist parasites of sympatric grazing mammals. In this study, we combined data from experimental exposures in cattle and sheep and natural infections in elk to compare the recruitment, morphology and reproduction of adult Dicrocoelium dendriticum, a generalist trematode that has emerged in sympatric grazing hosts in Cypress Hills Provincial Park, Alberta. Overall, there were no significant differences in the recruitment of metacercariae and in the pre-patency period of adults in experimentally exposed cattle and sheep. All flukes reached reproductive maturity and the degree of reproductive inequality between individual flukes within each infrapopulation was moderate and approximately equal among the three host species. Neither fluke size nor per capita fecundity was constrained by density dependence. Thus, fitness parameters associated with growth and reproduction were approximately equivalent among at least three species of definitive host, two of which are sympatric on pastures in this Park. The generalist life-history strategy of this trematode, which is known to extend to other stages of its life cycle, has likely contributed to its invasion history outside its native range in Europe.

  13. Predator interference effects on biological control: The "paradox" of the generalist predator revisited

    Parshad, Rana D.; Bhowmick, Suman; Quansah, Emmanuel; Basheer, Aladeen; Upadhyay, Ranjit Kumar

    2016-10-01

    An interesting conundrum in biological control questions the efficiency of generalist predators as biological control agents. Theory suggests, generalist predators are poor agents for biological control, primarily due to mutual interference. However field evidence shows they are actually quite effective in regulating pest densities. In this work we provide a plausible answer to this paradox. We analyze a three species model, where a generalist top predator is introduced into an ecosystem as a biological control, to check the population of a middle predator, that in turn is depredating on a prey species. We show that the inclusion of predator interference alone, can cause the solution of the top predator equation to blow-up in finite time, while there is global existence in the no interference case. This result shows that interference could actually cause a population explosion of the top predator, enabling it to control the target species, thus corroborating recent field evidence. Our results might also partially explain the population explosion of certain species, introduced originally for biological control purposes, such as the cane toad (Bufo marinus) in Australia, which now functions as a generalist top predator. We also show both Turing instability and spatio-temporal chaos in the model. Lastly we investigate time delay effects.

With funding from The Robert Wood Johnson Foundation Generalist Physician Initiative, NYMC developed strategies to attract applicants interested in primary care and to select primary care applicants for matriculation. These strategies included use of recruiting newsletters to describe the primary care curriculum, on-campus open houses for undergraduates, visits to regional undergraduate schools by generalist faculty, changes in the admission committee to include more generalists, and changes in the interview format to stress nonacademic qualities in applicants. The authors present data from the Association of American Medical Colleges (AAMC) Pre-Medical Student Questionnaire and from the AAMC Medical School Matriculation Questionnaire that indicate NYMC achieved its objectives. They warn, however, that it is unclear whether these changes occurred solely as a result of NYMC's strategies, as a result of market forces driving career choices, or as a result of some combination of these factors.

    How generalist plants diverge in response to pollinator selection without becoming specialized is still unknown. This study explores this question, focusing on the evolution of the pollination system in the pollination generalist Erysimum mediohispanicum (Brassicaceae). Pollinator assemblages were surveyed from 2001 to 2010 in 48 geo-referenced populations covering the entire geographic distribution of E. mediohispanicum. Bipartite modularity, a complex network tool, was used to find the pollination niche of each population. Evolution of the pollination niches and the correlated evolution of floral traits and pollination niches were explored using within-species comparative analyses. Despite being generalists, the E. mediohispanicum populations studied can be classified into five pollination niches. The boundaries between niches were not sharp, the niches differing among them in the relative frequencies of the floral visitor functional groups. The absence of spatial autocorrelation and phylogenetic signal indicates that the niches were distributed in a phylogeographic mosaic. The ancestral E. mediohispanicum populations presumably belonged to the niche defined by a high number of beetle and ant visits. A correlated evolution was found between pollination niches and some floral traits, suggesting the existence of generalist pollination ecotypes. It is conjectured that the geographic variation in pollination niches has contributed to the observed floral divergence in E. mediohispanicum. The process mediating this floral divergence presumably has been adaptive wandering, but the adaptation to the local pollinator faunas has been not universal. The outcome is a landscape where a few populations locally adapted to their pollination environment (generalist pollination ecotypes) coexist with many populations where this local adaptation has failed and where the plant phenotype is not primarily shaped by pollinators.

    Understanding how parasites fill their ecological niches requires information on the processes involved in the colonization and exploitation of unique host species. Switching to hosts with atypical attributes may favour generalists broadening their niches or may promote specialization and parasite diversification as the consequence. We analysed which blood parasites have successfully colonized hummingbirds, and how they have evolved to exploit such a unique habitat. We specifically asked (i) whether the assemblage of Haemoproteus parasites of hummingbirds is the result of single or multiple colonization events, (ii) to what extent these parasites are specialized in hummingbirds or shared with other birds and (iii) how hummingbirds contribute to sustain the populations of these parasites, in terms of both prevalence and infection intensity. We sampled 169 hummingbirds of 19 species along an elevation gradient in Southern Ecuador to analyse the host specificity, diversity and infection intensity of Haemoproteus by molecular and microscopy techniques. In addition, 736 birds of 112 species were analysed to explore whether hummingbird parasites are shared with other birds. Hummingbirds hosted a phylogenetically diverse assemblage of generalist Haemoproteus lineages shared with other host orders. Among these parasites, Haemoproteus witti stood out as the most generalized. Interestingly, we found that infection intensities of this parasite were extremely low in passerines (with no detectable gametocytes), but very high in hummingbirds, with many gametocytes seen. Moreover, infection intensities of H. witti were positively correlated with the prevalence across host species. Our results show that hummingbirds have been colonized by generalist Haemoproteus lineages on multiple occasions. However, one of these generalist parasites (H. witti) seems to be highly dependent on hummingbirds, which arise as the most relevant reservoirs in terms of both prevalence and

    This article aims to share critical debate on undertaking interviews with children in the home setting and draws on the authors' extensive research fieldwork. The article focuses on three key processes: planning entry to the child's home, conducting the interviews and exiting the field. In planning entry, we include children's engagement and issues of researcher gender. In conducting the interviews, we consider issues such as the balance of power, the importance of building a rapport, the voluntary nature of consent and the need for a flexible interview structure. Finally, we address exiting from the child's home with sensitivity at the end of the interview and/or research study. Undertaking research in the child's home provides a known and familiar territory for the child, but it means that the researcher faces a number of challenges that require solutions whilst they are a guest in a child's home. © The Author(s) 2014.

  10. The impact of workforce redesign policies on role boundaries in 'generalist' podiatry practice: expert views within the professional body.

    2014-01-01

    Demographic changes and a predicted rise in the prevalence of chronic illness have led to a range of health policies in the UK (and elsewhere) focused on workforce flexibility and extended roles for the allied health professions. Whilst much academic attention has been paid to extended specialised roles for allied health professionals such as podiatrists, little work has addressed the likely impact of these policy changes on non-specialist, 'generalist' podiatry practice. This study aimed to explore expert professional views on the impact of role flexibility on generalist podiatry practice. Expert podiatry practitioners drawn from within the professional body, the Society of Chiropodists and Podiatrists/College of Podiatry were recruited to 3 focus groups and 4 individual semi structured interviews and the data subject to a thematic analysis. Three key themes emerged, reflecting concerns about the future of generalist podiatry practice in the NHS, a perceived likelihood that generalist care will move inexorably towards private sector provision, and a growth in support worker grades undermining the position of generalist practice in the mainstream health division of labour. Up skilling generalist practitioners was viewed as the strongest defence against marginalisation. An emphasis on enhanced and specialised roles in podiatry by NHS commissioners and profession alike may threaten the sustainability of generalist podiatry provision in the state funded NHS. Non-specialist general podiatry may increasingly become the province of the private sector.

    The prospect of multidisciplinary assessment that considers the environmental impacts on the health of the population during the implementation of potentially polluting projects is incipient in Brazil. Considering the scenario of major undertakings in the country, broadening the outlook on the health and environment relationship based on social and economic development processes striving for environmentally sustainable projects is a key strategy. This article examines the debate on the relationship between the current development model, the risks, the environment and health and discusses the importance of the participation of the health sector in the environmental licensing procedures, which is the instrument of the Environmental Impact Assessment (EIA). Seeking to create more environmentally and socially sustainable territories, the health sector has been looking for opportunities to participate in the licensing processes of major undertakings from the EIA standpoint. Results of research conducted by the Ministry of Health have demonstrated the form of participation in these processes, highlighting the strengths and weaknesses that favor or hinder the increase of preventive actions in public health in the implementation of major undertakings in Brazil.

  12. Researcher or nurse? Difficulties of undertaking semi-structured interviews on sensitive topics.

    2014-09-01

    To reflect on the author's personal and professional journey when undertaking semi-structured interviews on sensitive topics with potentially vulnerable people. When discussing care at the end of life, researchers must accept that some participants may become distressed or emotional, depending on their previous experiences. Interviews that involve sensitive topics require careful planning. The semi-structured interviews were conducted as part of the author's PhD study examining the experiences of advance care planning among family caregivers of people with advanced dementia. A reflection on my personal and professional journey when undertaking semi-structured interviews on sensitive topics with potentially vulnerable people. The frustration and tragedy of dementia, as experienced by the family caregivers, were powerful and required the author to exert self-control to avoid being overly sympathetic and offering words of reassurance, agreement and comfort. This blurring of roles between researcher and nurse has implications for all nurse researchers who undertake qualitative interviews, particularly when an intense emotional response is likely. Nurse researchers should plan and prepare for potential blurring of roles during emotional interviews and should never automatically assume that they are sufficiently prepared as a result of their previous experience and nurse training.

    Panoramic radiography is a common radiographic examination carried out in the UK. This study was carried out to determine if acquisition site has an impact on image quality. An image quality audit was carried out in South Wales across a number of dental and general radiology settings. The image quality was assessed retrospectively against national standards. A total of 174 radiographs were assessed from general radiology departments and 141 from dental radiology units. Chi-squared analysis was used to investigate whether there were differences in the grading between dental radiology units and general radiology departments. Differences between the two settings in terms of the number of errors in the radiographs was analysed using the Mann-Whitney test. Chi-squared analysis was used to see if there were differences between the types of errors in the two clinical settings. There was a significant association (p = 0.021) between the quality of the radiograph grading and type of radiology department. However when excellent and diagnostically acceptable radiographs were grouped together there was no significant difference between the two clinical settings. Although the vast majority of radiographs were diagnostic (89% for general radiology and 92% for dental radiology units), neither reached the required standards. The most common errors were patient positioning errors (54.6% radiographs affected) and preparation/instructional errors (47.9% radiographs affected). Errors in panoramic radiography are relatively high and further instruction to staff undertaking these procedures is required to ensure the targets are reached.

    All Appalachian College of Pharmacy second-year students undertake the longitudinal geriatric early pharmacy practice experiences (EPPE) 2 course, which involves interacting with geriatric residents in two nursing facilities over two semesters. The study investigated the nursing staff's perceptions about the rotation and the pharmacy students' interaction with nursing facility residents. Cross-sectional study. Academic setting. 63 nursing facility staff. A 10-item attitude survey administered to nursing staff. Nursing staff attitude toward pharmacy students' interaction with geriatric residents during the course. Sixty-three responses were received (84% response rate). Most respondents were female (95.2%), who occasionally interacted with pharmacy students (54.8%) and had worked at the facilities for an average of 6.8 years (standard deviation [SD] = 6.7) years. Staff reported that pharmacy students practiced interacting with geriatric residents and nursing facility staff, learned about different medications taken by residents as well as their life as a nursing facility resident. In addition, the student visits improved the mood of residents and staff's understanding of medicines, among others. Staff suggested that students spend more time with their residents in the facility as well as ask more questions of staff. The nursing facility staff generally had favorable attitudes about pharmacy students' visits in their nursing facility. Nursing facility staff noted that the geriatric rotation was a great learning experience for the pharmacy students.

    Biotic homogenization (BH) is a process whereby some species (losers) are systematically replaced by others (winners). While this process has been related to the effects of anthropogenic activities, whether and how BH is occurring across regions and the role of native species as a driver of BH has hardly been investigated. Here, we examine the trend in the community specialization index (CSI) for 234 native species of breeding birds at 10,111 sites in six European countries from 1990 to 2008. Unlike many BH studies, CSI uses abundance information to estimate the balance between generalist and specialist species in local assemblages. We show that bird communities are more and more composed of native generalist species across regions, revealing a strong, ongoing BH process. Our result suggests a rapid and non-random change in community composition at a continental scale is occurring, most likely driven by anthropogenic activities.

  16. Cryptocephaline Egg Case Provides Incomplete Protection from Generalist Predators (Coleoptera: Chrysomelidae

    Full Text Available The egg case of Cryptocephalus rufipes (Goeze is described and illustrated. In laboratory trials, eggs of field-collected C. rufipes were observed for larval emergence (untreated control or exposed to two species of generalist predators, Chrysoperla carnea (Stephens or Xylocoris flavipes (Reuter in no-choice experiments. The behaviour of the predators upon contact with the C. rufipes eggs was observed. The number of hatching larvae was counted and compared. In the presence of each of the two species of predators, larval emergence was significantly reduced. Eggs that were not protected by an egg case were completely consumed by the predators. C. rufipes eggs were therefore incompletely protected from the studied generalist predators. This is the first study showing experimentally the protective function of cryptocephaline egg case.

  17. Kestrel-prey dynamic in a Mediterranean region: the effect of generalist predation and climatic factors.

    Directory of Open Access Journals (Sweden)

    Juan A Fargallo

    Full Text Available Most hypotheses on population limitation of small mammals and their predators come from studies carried out in northern latitudes, mainly in boreal ecosystems. In such regions, many predators specialize on voles and predator-prey systems are simpler compared to southern ecosystems where predator communities are made up mostly of generalists and predator-prey systems are more complex. Determining food limitation in generalist predators is difficult due to their capacity to switch to alternative prey when the basic prey becomes scarce.We monitored the population density of a generalist raptor, the Eurasian kestrel Falco tinnunculus over 15 years in a mountainous Mediterranean area. In addition, we have recorded over 11 years the inter-annual variation in the abundance of two main prey species of kestrels, the common vole Microtus arvalis and the eyed lizard Lacerta lepida and a third species scarcely represented in kestrel diet, the great white-toothed shrew Crocidura russula. We estimated the per capita growth rate (PCGR to analyse population dynamics of kestrel and predator species.Multimodel inference determined that the PCGR of kestrels was better explained by a model containing the population density of only one prey species (the common vole than a model using a combination of the densities of the three prey species. The PCGR of voles was explained by kestrel abundance in combination with annual rainfall and mean annual temperature. In the case of shrews, growth rate was also affected by kestrel abundance and temperature. Finally, we did not find any correlation between kestrel and lizard abundances.Our study showed for the first time vertebrate predator-prey relationships at southern latitudes and determined that only one prey species has the capacity to modulate population dynamics of generalist predators and reveals the importance of climatic factors in the dynamics of micromammal species and lizards in the Mediterranean region.

  20. Ethanol confers differential protection against generalist and specialist parasitoids of Drosophila melanogaster.

    As parasites coevolve with their hosts, they can evolve counter-defenses that render host immune responses ineffective. These counter-defenses are more likely to evolve in specialist parasites than generalist parasites; the latter face variable selection pressures between the different hosts they infect. Natural populations of the fruit fly Drosophila melanogaster are commonly threatened by endoparasitoid wasps in the genus Leptopilina, including the specialist L. boulardi and the generalist L. heterotoma, and both wasp species can incapacitate the cellular immune response of D. melanogaster larvae. Given that ethanol tolerance is high in D. melanogaster and stronger in the specialist wasp than the generalist, we tested whether fly larvae could use ethanol as an anti-parasite defense and whether its effectiveness would differ against the two wasp species. We found that fly larvae benefited from eating ethanol-containing food during exposure to L. heterotoma; we observed a two-fold decrease in parasitization intensity and a 24-fold increase in fly survival to adulthood. Although host ethanol consumption did not affect L. boulardi parasitization rates or intensities, it led to a modest increase in fly survival. Thus, ethanol conferred stronger protection against the generalist wasp than the specialist. We tested whether fly larvae can self-medicate by seeking ethanol-containing food after being attacked by wasps, but found no support for this hypothesis. We also allowed female flies to choose between control and ethanol-containing oviposition sites in the presence vs. absence of wasps and generally found significant preferences for ethanol regardless of wasp presence. Overall, our results suggest that D. melanogaster larvae obtain protection from certain parasitoid wasp species through their mothers' innate oviposition preferences for ethanol-containing food sources.

  1. Response of pest control by generalist predators to local-scale plant diversity: a meta-analysis.

    Disentangling the effects of plant diversity on the control of herbivores is important for understanding agricultural sustainability. Recent studies have investigated the relationships between plant diversity and arthropod communities at the landscape scale, but few have done so at the local scale. We conducted a meta-analysis of 32 papers containing 175 independent measures of the relationship between plant diversity and arthropod communities. We found that generalist predators had a strong positive response to plant diversity, that is, their abundance increased as plant diversity increased. Herbivores, in contrast, had an overall weak and negative response to plant diversity. However, specialist and generalist herbivores differed in their response to plant diversity, that is, the response was negative for specialists and not significant for generalists. While the effects of scale remain unclear, the response to plant diversity tended to increase for specialist herbivores, but decrease for generalist herbivores as the scale increased. There was no clear effect of scale on the response of generalist predators to plant diversity. Our results suggest that the response of herbivores to plant diversity at the local scale is a balance between habitat and trophic effects that vary according to arthropod specialization and habitat type. Synthesis and applications. Positive effects of plant diversity on generalist predators confirm that, at the local scale, plant diversification of agroecosystems is a credible and promising option for increasing pest regulation. Results from our meta-analysis suggest that natural control in plant-diversified systems is more likely to occur for specialist than for generalist herbivores. In terms of pest management, our results indicate that small-scale plant diversification (via the planting of cover crops or intercrops and reduced weed management) is likely to increase the control of specialist herbivores by generalist predators.

    Thiamine is a vitamin that has been shown to act as a trigger to activate plant defence and reduce pathogen and nematode infection as well as aphid settling and reproduction. We have here investigated whether thiamine treatments of seeds (i.e. seed dressing) would increase plant resistance against aphids and whether this would have different effects on a generalist than on specialist aphids. Seeds of wheat, barley, oat and pea were treated with thiamine alone or in combination with the biocontrol bacteria Pseudomonas chlororaphis MA 342 (MA 342). Plants were grown in climate chambers. The effects of seed treatment on fecundity, host acceptance and life span were studied on specialist aphids bird cherry-oat aphid (Rhopalosiphum padi L.) and pea aphid (Acyrthosiphon pisum Harris) and on the generalist green peach aphid (Myzus persicae, Sulzer). Thiamine seed treatments reduced reproduction and host acceptance of all three aphid species. The number of days to reproduction, the length of the reproductive life, the fecundity and the intrinsic rate of increase were found reduced for bird cherry-oat aphid after thiamine treatment of the cereal seeds. MA 342 did not have any effect in any of the plant-aphid combinations, except a weak decrease of pea aphid reproduction on pea. The results show that there are no differential effects of either thiamine or MA 342 seed treatments on specialist and generalist aphids and suggest that seed treatments with thiamine has a potential in aphid pest management.

    A key translational issue for neuroscience is to understand how genes affect individual differences in brain function. Although it is reasonable to suppose that genetic effects on specific learning abilities, such as reading and mathematics, as well as general cognitive ability (g), will overlap very little, the counterintuitive finding emerging from multivariate genetic studies is that the same genes affect these diverse learning abilities: a Generalist Genes hypothesis. To conclusively test this hypothesis, we exploited the widespread access to inexpensive and fast Internet connections in the UK to assess 2541 pairs of 10-year-old twins for reading, mathematics and g, using a web-based test battery. Heritabilities were 0.38 for reading, 0.49 for mathematics and 0.44 for g. Multivariate genetic analysis showed substantial genetic correlations between learning abilities: 0.57 between reading and mathematics, 0.61 between reading and g, and 0.75 between mathematics and g, providing strong support for the Generalist Genes hypothesis. If genetic effects on cognition are so general, the effects of these genes on the brain are also likely to be general. In this way, generalist genes may prove invaluable in integrating top-down and bottom-up approaches to the systems biology of the brain.

  5. Generalist solutions to overprescribing: a joint challenge for clinical and academic primary care.

    2014-01-01

    Polypharmacy is a phenomenon of modern health care that can offer benefits in terms of patient outcomes. Known risks associated with so-called inappropriate polypharmacy can be reduced through good medicine management and appropriate use of clinical guidelines. However, we now see a growing literature highlighting additional risks to individual well-being and social functioning not recognised within these existing frameworks - the burden of polypharmacy and a problem of overprescribing. We need a new approach to defining and understanding inappropriate polypharmacy from a person-centred perspective. This paper discusses practice-based work exploring the impact of introducing generalist needs assessment for elderly patients with multiple chronic morbidities. The work suggests that generalist care offers something 'different' to current chronic disease management models, but highlights the need for formal evaluation to determine whether it is 'better'. We call for new collaborative research between clinical and academic partners to address the question as to whether generalist care offers solutions to the problems of the burden of polypharmacy.

    Arbuscular mycorrhiza (AM) formed between plants and AM fungi (AMF) can alter host plant quality and thus influence plant-herbivore interactions. While AM is known to affect the development of generalist chewing-biting herbivores, AM-mediated impacts on insect behavior have been neglected until now. In this study, the effects of Rhizophagus irregularis, a generalist AMF, on phenotypic and leaf metabolic traits of Plantago major plants were investigated. Further, the influence of AM-mediated host plant modifications on the development and on seven behavioral traits of larvae of the generalist Mamestra brassicae were recorded. Tests were carried out in the third (L3) and fourth (L4) larval instar, respectively. While shoot water content, specific leaf area, and foliar concentrations of the secondary metabolite aucubin were higher in AM-treated compared to non-mycorrhized (NM) plants, lower concentrations of the primary metabolites citric acid and isocitric acid were found in leaves of AM plants. Larvae reared on AM plants gained a higher body mass and tended to develop faster than individuals reared on NM plants. However, plant treatment had no significant effect on any of the behavioral traits. Instead, differences between larvae of different ages were detected in several behavioral features, with L4 being less active and less bold than L3 larvae. The results demonstrate that AM-induced modifications of host plant quality influence larval development, whereas the behavioral phenotype seems to be more fixed at least under the tested conditions.

    According to theoretical predictions, endothermic homeotherms can be classified as either thermal specialists or thermal generalists. In high cost environments, thermal specialists are supposed to be more prone to using facultative heterothermy than generalists. We tested this hypothesis at the intraspecific level using male laboratory mice (C57BL/cmdb) fasted under different thermal conditions (20 and 10°C) and for different time periods (12-48 h). We predicted that variability of body temperature ( T b ) and time spent with T b below normothermy would increase with the increase of environmental demands (duration of fasting and cold). To verify the above prediction, we measured T b and energy expenditure of fasted mice. We did not record torpor bouts but we found that variations in T b and time spent in hypothermia increased with environmental demands. In response to fasting, mice also decreased their energy expenditure. Moreover, animals that showed more precise thermoregulation when fed had more variable T b when fasted. We postulate that the prediction of the thermoregulatory generalist-specialist trade-off can be applied at the intraspecific level, offering a valid tool for identifying mechanistic explanations of the differences in animal responses to variations in energy supply. © 2017.

    Although much of the theory on the success of invasive species has been geared at escape from specialist enemies, the impact of introduced generalist invertebrate herbivores on both native and introduced plant species has been underappreciated. The role of nocturnal invertebrate herbivores in structuring plant communities has been examined extensively in Europe, but less so in North America. Many nocturnal generalists (slugs, snails, and earwigs) have been introduced to North America, and 96% of herbivores found during a night census at our California Central Valley site were introduced generalists. We explored the role of these herbivores in the distribution, survivorship, and growth of 12 native and introduced plant species from six families. We predicted that introduced species sharing an evolutionary history with these generalists might be less vulnerable than native plant species. We quantified plant and herbivore abundances within our heterogeneous site and also established herbivore removal experiments in 160 plots spanning the gamut of microhabitats. As 18 collaborators, we checked 2000 seedling sites every day for three weeks to assess nocturnal seedling predation. Laboratory feeding trials allowed us to quantify the palatability of plant species to the two dominant nocturnal herbivores at the site (slugs and earwigs) and allowed us to account for herbivore microhabitat preferences when analyzing attack rates on seedlings. The relationship between local slug abundance and percent cover of five common plant taxa at the field site was significantly negatively associated with the mean palatability of these taxa to slugs in laboratory trials. Moreover, seedling mortality of 12 species in open-field plots was positively correlated with mean palatability of these taxa to both slugs and earwigs in laboratory trials. Counter to expectations, seedlings of native species were neither more vulnerable nor more palatable to nocturnal generalists than those of

    This paper presents one aspect of a larger study identifying key influences on curriculum redesign and development of a post-graduate diploma in advanced clinical nursing. The focus is on paediatric intensive care and general paediatric streams. Data presented here relate to registered nurses' perceptions of benefits and barriers when undertaking this post-graduate diploma. As well as interviews and focus group discussions with a number of nurses, data were collected through a self-administered questionnaire, A total of 885 surveys were distributed to nurses working in paediatric areas in five hospitals in Victoria, Australia. Of these, 391 were completed (response rate 44%). One hundred and thirty (33%) had post-registration or post-graduate paediatric qualifications. Perceived benefits of undertaking the post-graduate diploma mainly related to an increase in knowledge and experience and improvement of employment opportunities. Perceived barriers mainly related to financial and professional issues such as cost of the course, loss of salary, the lack of direct remuneration on completion of the course and a lack of promotional opportunities. It was of concern that several nurses expressed a belief that paediatric qualifications were unnecessary and that many believed their employers did not value the qualification. Several recommendations are suggested to address the main barriers. These include more flexibility in the provision of such courses and opportunities for financial assistance.

    The lack of adequate documentation of deaths, and particularly their cause, is often noted in African and Asian settings, but practical solutions for addressing the problem are not always clear. Verbal autopsy methods (interviewing witnesses after a death) have developed rapidly, but there remains a lack of clarity as to how these methods can be effectively applied to large unregistered populations. This paper sets out practical details for undertaking a representative survey of cause-specific mortality in a population of several million, taking Tigray Region in Ethiopia as a prototype. Sampling was designed around an expected level of maternal mortality ratio of 400 per 100,000 live births, which needed measuring within a 95% confidence interval of approximately ±100. Taking a stratified cluster sample within the region at the district level for logistic reasons, and allowing for a design effect of 2, this required a population of around 900,000 people, equating to six typical districts. Since the region is administered in six geographic zones, one district per zone was randomly selected. The survey was implemented as a two-stage process: first, to trace deaths that occurred in the sampled districts within the preceding year, and second to follow them up with verbal autopsy interviews. The field work for both stages was undertaken by health extension workers, working in their normally assigned areas. Most of the work was associated with tracing the deaths, rather than undertaking the verbal autopsy interviews. This approach to measuring cause-specific mortality in an unregistered Ethiopian population proved to be feasible and effective. Although it falls short of the ideal situation of continuous civil registration and vital statistics, a survey-based strategy of this kind may prove to be a useful intermediate step on the road towards full civil registration and vital statistics implementation.

    Adaption to dietary changes is critical in the evolution of host plant ranges in polyphagous insects. We compared three taxa of lepidopteran herbivores from the predominantly generalist genus Spodoptera showing different degrees of polyphagy: Spodoptera littoralis, with a broad host range including both mono- and dicotyledonous plants, and two Spodoptera frugiperda strains [Corn (i.e. maize) (C) and Rice (R)] adapted primarily to different grass species. When feeding on maize we show a lower performance in the broad generalist taxon compared to the grass adapted taxa. Among these taxa, the maize adapted S. frugiperda C-strain generally performed better than the R-strain on maize leaves. On artificial pinto diet, all taxa performed well. Our RNA-Seq analysis of midgut transcriptomes from 3rd instar larvae feeding on maize showed broader transcriptional readjustments in the generalist S. littoralis compared to grass adapted S. frugiperda strains. Substantial alteration in the expression levels of midgut physiological function related transcripts, such as digestive and detoxifying enzymes, transporters, immunity, and peritrophic membrane associated transcripts, existed in all taxa. We found high background expression of UDP-glucosyl transferases, which are known to neutralize maize leaf toxins, in the maize adapted S. frugiperda C-strain, contributing to its fitness on maize compared to the R-strain. Our findings provide evidence for divergent diet specific response of digestive physiology within these Spodoptera taxa. Unexpectedly, the C- and R-strains of S. frugiperda fed on the same diet showed large differences in expression patterns between these two closely related taxa. Copyright © 2016.

  18. Host phenology and geography as drivers of differentiation in generalist fungal mycoparasites.

    Directory of Open Access Journals (Sweden)

    Alexandra Pintye

    Full Text Available The question as to why parasites remain generalist or become specialist is a key unresolved question in evolutionary biology. Ampelomyces spp., intracellular mycoparasites of powdery mildew fungi, which are themselves plant pathogens, are a useful model for studies of this issue. Ampelomyces is used for the biological control of mildew. Differences in mycohost phenology promote temporal isolation between sympatric Ampelomyces mycoparasites. Apple powdery mildew (APM causes spring epidemics, whereas other powdery mildew species on plants other than apple cause epidemics later in the season. This has resulted in genetic differentiation between APM and non-APM strains. It is unclear whether there is genetic differentiation between non-APM Ampelomyces lineages due to their specialization on different mycohosts. We used microsatellites to address this question and found no significant differentiation between non-APM Ampelomyces strains from different mycohosts or host plants, but strong differentiation between APM and non-APM strains. A geographical structure was revealed in both groups, with differences between European countries, demonstrating restricted dispersal at the continent scale and a high resolution for our markers. We found footprints of recombination in both groups, possibly more frequent in the APM cluster. Overall, Ampelomyces thus appears to be one of the rare genuine generalist pathogenic fungi able to parasitize multiple hosts in natural populations. It is therefore an excellent model for studying the evolution of pathogens towards a generalist rather than host-specific strategy, particularly in light of the tritrophic interaction between Ampelomyces mycoparasites, their powdery mildew fungal hosts and the mildew host plants.

  19. Pollen limitation and reproductive assurance in Antillean Gesnerieae: a specialists vs. generalist comparison.

    Pollen limitation of female fecundity is widespread among angiosperms, a signal that pollinators frequently fail to transfer pollen to fertilize all ovules. Recent surveys have suggested that pollen limitation is associated with floral specialization. This study uses a group of Antillean Gesneriaceae with contrasting pollination systems (bat, hummingbird, and generalist) to assess the premise that plants with specialized pollination systems and infrequent pollinator visitation experience greater pollen limitation of fruit and seed set than their generalist congeners. Alternatively, specialists may possess mechanisms that reduce pollen limitation, such as autonomous self-pollination. A survey of autonomous self-pollination conducted on 13 Gesneria and Rhytidophyllum species during 2006-2008 revealed no significant association between reproductive assurance mechanisms and pollination system specialization. However, high levels of potential autonomous self-pollination were only found among specialized hummingbird-pollinated species. A comparison of fruit and seed set between emasculated and unmanipulated flowers provided evidence for autonomous selfing acting as a reproductive assurance mechanism in three out of four ornithophilous species. Furthermore, the Puerto Rican population of G. reticulata relies almost exclusively on self-pollination for reproduction. Two-year pollen supplementation experiments conducted on nine Gesnerieae species from the Dominican Republic and Puerto Rico provided evidence for significant pollen limitation associated with pollination specialization including both bat- and hummingbird-pollinated Gesnerieae; no pollen limitation was detected in any of the four generalist species. No pollen limitation was detected either in two ornithophilous Gesneria species with low hummingbird visitation and high levels of autonomous self-pollination. This study provides support for the idea that generalized pollination systems may, in some cases, buffer

  20. Influence of intraguild predation among generalist insect predators on the suppression of an herbivore population.

    We evaluated the influence of intraguild predation among generalist insect predators on the suppression of an herbivore, the aphid Aphis gossypii, to test the appropriateness of the simple three trophic level model proposed by Hairston, Smith, and Slobodkin (1960). We manipulated components of the predator community, including three hemipteran predators and larvae of the predatory green lacewing Chrysoperla carnea, in field enclosure/exclosure experiments to address four questions: (1) Do generalist hemipteran predators feed on C. carnea? (2) Does intraguild predation (IGP) represent a substantial source of mortality for C. carnea? (3) Do predator species act in an independent, additive manner, or do significant interactions occur? (4) Can the experimental addition of some predators result in increased densities of aphids through a trophic cascade effect? Direct observations of predation in the field demonstrated that several generalist predators consume C. carnea and other carnivorous arthropods. Severely reduced survivorship of lacewing larvae in the presence of other predators showed that IGP was a major source of mortality. Decreased survival of lacewing larvae was primarily a result of predation rather than competition. IGP created significant interactions between the influences of lacewings and either Zelus renardii or Nabis predators on aphid population suppression. Despite the fact that the trophic web was too complex to delineate distinct trophic levels within the predatory arthropod community, some trophic links were sufficiently strong to produce cascades from higher-order carnivores to the level of herbivore population dynamics: experimental addition of either Z. renardii or Nabis predators generated sufficient lacewing larval mortality in one experiment to release aphid populations from regulation by lacewing predators. We conclude that intraguild predation in this system is wide-spread and has potentially important influences on the population

    Full Text Available Background: Any activity undertaken for the purpose of health enhancing behavior is an important element of taking care of one's health. The aim of this paper was to analyze the frequency of health enhancing behaviors and avoiding health-risk behaviors among teachers and other school staff by gender and age. Material and Methods: The sample consisted of 750 teachers and 259 individuals of non-teaching staff of 22 health promoting schools. A questionnaire that included Positive Health Behaviors Scale for Adults and questions on avoiding risk behaviors were used as a research tool. Results: Of the 32 analyzed health enhancing (positive behaviors, only 11 were undertaken by teachers and 10 by non-teaching staff at a desirable frequency (always or almost always in a group of more than 50% of respondents. Almost one third of health enhancing behaviors were undertaken with this frequency by less than 20% of respondents. The highest deficits concerned physical activity, nutrition and mental health-related behaviors, and the lowest concerned safety. Deficits in all positive health behaviors were smaller in teachers than in non-teaching staff, in women than in men and in older than in younger teachers. The majority of respondents, mostly teachers, irrespective of gender and age did not undertake risk behaviors. Conclusions: There was a lot of deficits in the healthy lifestyle of teachers and other school workers what is alarming from the point of view of school workers' health, their tasks and their role in shaping positive health behavior in children and adolescents. There is a great need for taking actions to improve the situation, such as the development of health promotion programs addressed to teachers and other school staff, including issues concerning healthy lifestyles in teacher's pre- and in-service training, counselling in the area of healthy lifestyle in preventive health care of school staff.

    A national survey of family physicians, general internists, and general pediatricians was conducted in the US to examine differences among the three groups of generalists physicians, with particular regard to the factors influencing their choice of generalist career. Family physicians were more likely to have made their career decision before medical school, and were more likely to have come from inner-city or rural areas. Personal values and early role models play a very important role in influencing their career choice. In comparison, a higher proportion of general internists had financial aid service obligations and their choice of the specialty was least influenced by personal values. General pediatricians had more clinical experiences either in primary care or with underserved populations, and they regarded medical school experiences as more important in influencing their specialty choice than did the other two groups. Admission committees may use these specialty-related factors to develop strategies to attract students into each type of generalist career.

  7. Does undertaking an intercalated BSc influence first clinical year exam results at a London medical school?

    Intercalated BScs (iBScs) are an optional part of the medical school curriculum in many Universities. Does undertaking an iBSc influence subsequent student performance? Previous studies addressing this question have been flawed by iBSc students being highly selected. This study looks at data from medical students where there is a compulsory iBSc for non-graduates. Our aim was to see whether there was any difference in performance between students who took an iBSc before or after their third year (first clinical year) exams. A multivariable analysis was performed to compare the third year results of students at one London medical school who had or had not completed their iBSc by the start of this year (n = 276). A general linear model was applied to adjust for differences between the two groups in terms of potential confounders (age, sex, nationality and baseline performance). The results of third year summative exams for 276 students were analysed (184 students with an iBSc and 92 without). Unadjusted analysis showed students who took an iBSc before their third year achieved significantly higher end of year marks than those who did not with a mean score difference of 4.4 (0.9 to 7.9 95% CI, p = 0.01). (overall mean score 238.4 "completed iBSc" students versus 234.0 "not completed", range 145.2 - 272.3 out of 300). There was however a significant difference between the two groups in their prior second year exam marks with those choosing to intercalate before their third year having higher marks. Adjusting for this, the difference in overall exam scores was no longer significant with a mean score difference of 1.4 (-4.9 to +7.7 95% CI, p = 0.66). (overall mean score 238.0 " completed iBSc" students versus 236.5 "not completed"). Once possible confounders are controlled for (age, sex, previous academic performance) undertaking an iBSc does not influence third year exam results. One explanation for this confounding in unadjusted results is that students who do better

    2016-12-01

    The alternative prey hypothesis (APH) states that when the density of the main prey declines, generalist predators switch to alternative prey and vice versa, meaning that predation pressure on the alternative prey should be negatively correlated with the density of the main prey. We tested the APH in a system comprising one generalist predator (pine marten, Martes martes), cyclic main prey (microtine voles, Microtus agrestis and Myodes glareolus) and alternative prey (cavity nests of common goldeneye, Bucephala clangula); pine marten is an important predator of both voles and common goldeneye nests. Specifically, we studied whether annual predation rate of real common goldeneye nests and experimental nests is negatively associated with fluctuation in the density of voles in four study areas in southern Finland in 2000-2011. Both vole density and nest predation rate varied considerably between years in all study areas. However, we did not find support for the hypothesis that vole dynamics indirectly affects predation rate of cavity nests in the way predicted by the APH. On the contrary, the probability of predation increased with vole spring abundance for both real and experimental nests. Furthermore, a crash in vole abundance from previous autumn to spring did not increase the probability of predation of real nests, although it increased that of experimental nests. We suggest that learned predation by pine marten individuals, coupled with efficient search image for cavities, overrides possible indirect positive effects of high vole density on the alternative prey in our study system.

  9. Landscape fragmentation generates spatial variation of diet composition and quality in a generalist herbivore.

    Forest fragmentation may benefit generalist herbivores by increasing access to various substitutable food resources, with potential consequences for their population dynamics. We studied a European roe deer (Capreolus capreolus) population living in an agricultural mosaic of forest, woodlots, meadows and cultivated crops. We tested whether diet composition and quality varied spatially across the landscape using botanical analyses of rumen contents and chemical analyses of the plants consumed in relation to landscape metrics. In summer and non-mast winters, roe deer ate more cultivated seeds and less native forest browse with increasing availability of crops in the local landscape. This spatial variation resulted in contrasting diet quality, with more cell content and lower lignin and hemicellulose content (high quality) for individuals living in more open habitats. The pattern was less marked in the other seasons when diet composition, but not diet quality, was only weakly related to landscape structure. In mast autumns and winters, the consumption of acorns across the entire landscape resulted in a low level of differentiation in diet composition and quality. Our results reflect the ability of generalist species, such as roe deer, to adapt to the fragmentation of their forest habitat by exhibiting a plastic feeding behavior, enabling them to use supplementary resources available in the agricultural matrix. This flexibility confers nutritional advantages to individuals with access to cultivated fields when their native food resources are depleted or decline in quality (e.g. during non-mast years) and may explain local heterogeneities in individual phenotypic quality.

  10. A specific mix of generalists: bacterial symbionts in Mediterranean Ircinia spp.

    2012-03-01

    Microbial symbionts form abundant and diverse components of marine sponge holobionts, yet the ecological and evolutionary factors that dictate their community structure are unresolved. Here, we characterized the bacterial symbiont communities of three sympatric host species in the genus Ircinia from the NW Mediterranean Sea, using electron microscopy and replicated 16S rRNA gene sequence clone libraries. All Ircinia host species harbored abundant and phylogenetically diverse symbiont consortia, comprised primarily of sequences related to other sponge-derived microorganisms. Community-level analyses of bacterial symbionts revealed host species-specific genetic differentiation and structuring of Ircinia-associated microbiota. Phylogenetic analyses of host sponges showed a close evolutionary relationship between Ircinia fasciculata and Ircinia variabilis, the two host species exhibiting more similar symbiont communities. In addition, several bacterial operational taxonomic units were shared between I. variabilis and Ircinia oros, the two host species inhabiting semi-sciophilous communities in more cryptic benthic habitats, and absent in I. fasciculata, which occurs in exposed, high-irradiance habitats. The generalist nature of individual symbionts and host-specific structure of entire communities suggest that: (1) a 'specific mix of generalists' framework applies to bacterial symbionts in Ircinia hosts and (2) factors specific to each host species contribute to the distinct symbiont mix observed in Ircinia hosts. © 2011 Federation of European Microbiological Societies.

    Emerging infectious disease outbreaks are increasingly suspected to be a consequence of human pressures exerted on natural ecosystems. Previously, host taxonomic communities have been used as indicators of infectious disease emergence, and the loss of their diversity has been implicated as a driver of increased presence. The mechanistic details in how such pathogen-host systems function, however, may not always be explained by taxonomic variation or loss. Here we used machine learning and methods based on Gower's dissimilarity to quantify metrics of invertebrate functional diversity, in addition to functional groups and their taxonomic diversity at sites endemic and non-endemic for the model generalist pathogen Mycobacterium ulcerans, the causative agent of Buruli ulcer. Changes in these metrics allowed the rapid categorisation of the ecological niche of the mycobacterium's hosts and the ability to relate specific host traits to its presence in aquatic ecosystems. We found that taxonomic diversity of hosts and overall functional diversity loss and evenness had no bearing on the mycobacterium's presence, or whether the site was in an endemic area. These findings, however, provide strong evidence that generalist environmentally persistent bacteria such as M. ulcerans can be associated with specific functional traits rather than taxonomic groups of organisms, increasing our understanding of emerging disease ecology and origin.

    Adults of a generalist herbivore, the lubber grasshopper,Romalea guttata, can be converted to functional specialists by feeding them exclusively on catnip,Nepeta cataria. No obvious adverse effects on adult development resulted from this enforced monophagy. Notwithstanding the fact thatR. guttata has had no coevolutionary relationship with this Eurasian mint, it readily sequesters compounds that are identical to or derived from the terpenoid lactones that are characteristic ofN. cataria. R. guttata appears to both biomagnify minor allelochemicals and to sequester metabolites of theNepeta terpenes in its paired defensive glands. The levels of autogenously produced phenolics are not affected by feeding onN. cataria and the defensive secretions of catnip-fed grasshoppers are more repellent to ants than those of wild-fed acridids. Metabolites of theN. cataria monoterpenes are sequestered in the defensive glands when catnip is added to the natural diet ofR. guttata. The ability of a generalist,R. guttata, to facilely bioaccumulate a potpourri of foreign allelochemicals when feeding in a specialist mode is analyzed in terms of its biochemical, physiological, and functional significance. Sequestration is examined as a response to the enteric effronteries represented by the phytochemicals that can be characteristic of the "overload" in a monophagous diet.

    Full Text Available Mountain lizards are highly vulnerable to climate change, and the continuous warming of their habitats could be seriously threatening their survival. We aim to compare the thermal ecology and microhabitat selection of a mountain lizard, Iberolacerta galani, and a widely distributed lizard, Podarcis bocagei, in a montane area. Both species are currently in close syntopy in the study area, at 1,400 m above the sea level. We determined the precision, accuracy and effectiveness of thermoregulation, and the thermal quality of habitat for both species. We also compared the selection of thermal microhabitats between both species. Results show that I. galani is a cold-adapted thermal specialist with a preferred temperature range of 27.9–29.7 °C, while P. bocagei would be a thermal generalist, with a broader and higher preferred temperature range (30.1–34.5 °C. In addition, I. galani selects rocky substrates while P. bocagei selects warmer soil and leaf litter substrates. The thermal quality of the habitat is higher for P. bocagei than for I. galani. Finally, P. bocagei achieves a significantly higher effectiveness of thermoregulation (0.87 than I. galani (0.80. Therefore, these mountain habitat conditions seem currently more suitable for performance of thermophilic generalist lizards than for cold-specialist lizards.

    The Future of Pediatric Education II (FOPE II) Project was a 3-year, grant-funded initiative, which continued the work begun by the 1978 Task Force on the Future of Pediatric Education. Its primary goal was to proactively provide direction for pediatric education for the 21st century. To achieve this goal, 5 topic-specific workgroups were formed: 1) the Pediatric Generalists of the Future Workgroup, 2) the Pediatric Specialists of the Future Workgroup, 3) the Pediatric Workforce Workgroup, 4) the Financing of Pediatric Education Workgroup, and 5) the Education of the Pediatrician Workgroup. The FOPE II Final Report was recently published as a supplement to Pediatrics (The Future of Pediatric Education II: organizing pediatric education to meet the needs of infants, children, adolescents, and young adults in the 21st century. Pediatrics. 2000;105(suppl):161-212). It is also available on the project web site at: This report reflects the deliberations and recommendations of the Pediatric Generalists of the Future Workgroup of the Task Force on FOPE II. The report looks at 5 factors that have led to changes in child health needs and pediatric practice over the last 2 decades. The report then presents a vision for the role and scope of the pediatrician of the future and the core attributes, skills, and competencies pediatricians caring for infants, children, adolescents, and young adults will need in the 21st century.

    Recurrent cycles of climatic change during the Quaternary period have dramatically affected the population genetic structure of many species. We reconstruct the recent demographic history of the coyote (Canis latrans) through the use of Bayesian techniques to examine the effects of Late Quaternary climatic perturbations on the genetic structure of a highly mobile generalist species. Our analysis reveals a lack of phylogeographic structure throughout the range but past population size changes correlated with climatic changes. We conclude that even generalist carnivorous species are very susceptible to environmental changes associated with climatic perturbations. This effect may be enhanced in coyotes by interspecific competition with larger carnivores.

    This article, the second in a series of articles on Leading Better Care, describes the actions undertaken in recent years in NHS Lanarkshire to improve selection processes for nursing, midwifery and allied health professional (NMAHP) posts. This is an area of significant interest to these professions, management colleagues and patients given the pivotal importance of NMAHPs to patient care and experience. In recent times the importance of selecting staff not only with the right qualifications but also with the right attributes has been highlighted to ensure patients are well cared for in a safe, effective and compassionate manner. The article focuses on NMAHP selection processes, tracking local, collaborative development work undertaken to date. It presents an overview of some of the work being implemented, highlights a range of important factors, outlines how evaluation is progressing and concludes by recommending further empirical research.

    2015-03-01

    Life story work is increasingly being used with people with dementia; this work offers a critical appraisal of some challenges that may be faced in practice. An in-depth case study analysis was undertaken to understand the experiences of people with dementia, family carers and care staff in using life story work in an NHS Mental Health and Social Care Trust. Data collection included semi-structured interviews, observation, conversations and field notes. Private memories were sometimes recalled by the person with dementia that were not for inclusion in any written product; enabling the person with dementia to tell their own life story could be a challenge; quality of the life story books was variable and; at times, life story work may be overused with the person with dementia. Services should not be deterred from undertaking life story work with people with dementia, but there is a need to adopt a planned approach to its implementation that includes facilitation, education and supervision. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  1. A Generalist Protist Predator Enables Coexistence in Multitrophic Predator-Prey Systems Containing a Phage and the Bacterial Predator Bdellovibrio

    Directory of Open Access Journals (Sweden)

    Julia Johnke

    2017-10-01

    Full Text Available Complex ecosystems harbor multiple predators and prey species whose direct and indirect interactions are under study. In particular, the combined effects of predator diversity and resource preference on prey removal are not known. To understand the effect of interspecies interactions, combinations of micro-predators—i.e., protists (generalists, predatory bacteria (semi-specialists, and phages (specialists—and bacterial prey were tracked over a 72-h period in miniature membrane bioreactors. While specialist predators alone drove their preferred prey to extinction, the inclusion of a generalist resulted in uniform losses among prey species. Most importantly, presence of a generalist predator enabled coexistence of all predators and prey. As the generalist predator also negatively affected the other predators, we suggest that resource partitioning between predators and the constant availability of resources for bacterial growth due to protist predation stabilizes the system and keeps its diversity high. The appearance of resistant prey strains and subsequent evolution of specialist predators unable to infect the ancestral prey implies that multitrophic communities are able to persist and stabilize themselves. Interestingly, the appearance of BALOs and phages unable to infect their prey was only observed for the BALO or phage in the absence of additional predators or prey species indicating that competition between predators might influence coevolutionary dynamics.

    To improve the success of integrated pest management (IPM) in apple orchards, we investigated whether generalist phytoseiid mites have suppressed the occurrence of Tetranychus urticae. In Akita Prefecture, northern Japan, in 2012 and 2013, two types of experimental plot were compared. Conservation plots had been managed for the conservation of generalist phytoseiid mites by selective chemical spraying without mowing since 2009. Conventional plots were managed by non-selective chemical spraying with regular mowing. The conservation plots had significantly fewer T. urticae adult females per tree in both years. Two species of generalist phytoseiid mites-Typhlodromus vulgaris and Amblyseius tsugawai-were continuously present in the conservation plots, with only a few T. urticae. The conservation plots had significantly more A. tsugawai adult females in the undergrowth in both years, and significantly more T. vulgaris adult females on apple leaves in 2012. Typhlodromus vulgaris was continuously present in the conservation plots but was scarce from late May to early August in the conventional plots. In the presence of T. vulgaris, low numbers of T. urticae did not increase on apple leaves. These results indicate that the generalist phytoseiid mites serve as important biological control agents in IPM in apple orchards.

  6. Genetic architecture of pollination syndrome transition between hummingbird-specialist and generalist species in the genus Rhytidophyllum (Gesneriaceae

    Directory of Open Access Journals (Sweden)

    Hermine Alexandre

    2015-06-01

    Full Text Available Adaptation to pollinators is a key factor of diversification in angiosperms. The Caribbean sister genera Rhytidophyllum and Gesneria present an important diversification of floral characters. Most of their species can be divided in two major pollination syndromes. Large-open flowers with pale colours and great amount of nectar represent the generalist syndrome, while the hummingbird-specialist syndrome corresponds to red tubular flowers with a less important nectar volume. Repeated convergent evolution toward the generalist syndrome in this group suggests that such transitions rely on few genes of moderate to large effect. To test this hypothesis, we built a linkage map and performed a QTL detection for divergent pollination syndrome traits by crossing one specimen of the generalist species Rhytidophyllum auriculatum with one specimen of the hummingbird pollinated R. rupincola. Using geometric morphometrics and univariate traits measurements, we found that floral shape among the second-generation hybrids is correlated with morphological variation observed between generalist and hummingbird-specialist species at the genus level. The QTL analysis showed that colour and nectar volume variation between syndromes involve each one major QTL while floral shape has a more complex genetic basis and rely on few genes of moderate effect. Finally, we did not detect any genetic linkage between the QTLs underlying those traits. This genetic independence of traits could have facilitated evolution toward optimal syndromes.

  8. Cumulative effects of transgenerational induction on plant palatability to generalist and specialist herbivores

    Directory of Open Access Journals (Sweden)

    I. P. Neylan

    2018-03-01

    Full Text Available Herbivore damage can induce anti-herbivore traits in plants. However, there is little data regarding how these induced traits affect a plant's palatability (an important factor in determining the likelihood and magnitude of herbivore damage across multiple generations post-induction, or whether the effect of transgenerational induction differs between generalist and specialist herbivores. Here we used palatability as a measure of the effects of transgenerational defensive induction in wild radish plants. We conducted a greenhouse experiment to determine whether generalist (slugs and specialist (caterpillars of the white cabbage butterfly herbivores' preference for wild radish differed depending on the number of previous generations that experienced herbivory. We found lowered palatability in plants with two or three inductions in their past in the case of generalist slugs, while palatability to a specialist herbivore was not affected by transgenerational induction. We conclude that the history of herbivory experienced by a plant's ancestors over multiple generations may play an important role in its ability to defend itself against generalist herbivores, but not against the specialists with whom they have co-evolved. Our findings suggest that the effects that multiple past inductions may have on palatability down the family line can be expected to have ecological and evolutionary implications.

    Unruh, Brandon T; Gunderson, John G

    2016-01-01

    While the public health burden posed by borderline personality disorder (BPD) rivals that associated with other major mental illnesses, the prevailing disposition of psychiatrists toward the disorder remains characterized by misinformation, stigma, aversive attitudes, and insufficient familiarity with effective generalist treatments that can be delivered in nonspecialized health care settings. Residency training programs are well positioned to better equip the next generation of psychiatrists to address these issues, but no consensus or guidelines currently exist for what and how residents should be taught about managing BPD. Instead, disproportionately limited curricular time, teaching of non-evidence-based approaches, and modeling of conceptually confused combinations of techniques drawn from specialty BPD treatments are offered. In this article, we (1) explain why training in a generalist model is sensible and why alternative approaches are not appropriate for residents, (2) propose a plan for giving residents adequate training via a generalist model, highlighting minimal didactic and clinical-training objectives (dubbed "core competencies" and "milestones") and a model curriculum developed at the Massachusetts General Hospital/McLean Hospital residency program, and (3) describe obstacles to implementation of effective generalist training posed by infrastructural, faculty-centered, and resident-centered variables.

    2016-11-01

    Full Text Available Background. Critical care transfers (CCT refer to the high level of care given during transport (via ambulance, helicopter or fixed-wing aircraft of patients who are of high acuity. In South Africa (SA, advanced life support (ALS paramedics undertake CCTs. The scope of ALS in SA has no extended protocol regarding procedures or medications in terms of dealing with these CCTs. Aim. The aim of this study was to obtain the opinions of several experts in fields pertaining to critical care and transport and to gain consensus on the skills and scope-of-practice requirements of paramedics undertaking CCTs in the SA setting. Methods. A modified Delphi study consisting of three rounds was undertaken using an online survey platform. A heterogeneous sample (n=7, consisting of specialists in the fields of anaesthesiology, emergency medicine, internal medicine, critical care, critical care transport and paediatrics, was asked to indicate whether, in their opinion, selected procedures and medications were needed within the scope of practice of paramedics undertaking CCTs. Results. After three rounds, consensus was obtained in 70% (57/81 of procedures and medications. Many of these items are not currently within the scope of paramedics’ training. The panel felt that paramedics undertaking these transfers should have additional postgraduate training that is specific to critical care. Conclusion. Major discrepancies exist between the current scope of paramedic practice and the suggested required scope of practice for CCTs. An extended scope of practice and additional training should be considered for these practitioners.

    Haas, Sarah E.; Hooten, Mevin B.; Rizzo, David M.; Meentemeyer, Ross K.

    2011-01-01

    Empirical evidence suggests that biodiversity loss can increase disease transmission, yet our understanding of the 'diversity-disease hypothesis' for generalist pathogens in natural ecosystems is limited. We used a landscape epidemiological approach to examine two scenarios regarding diversity effects on the emerging plant pathogen Phytophthora ramorum across a broad, heterogeneous ecoregion: (1) an amplification effect exists where disease risk is greater in areas with higher plant diversity due to the pathogen's wide host range, or (2) a dilution effect where risk is reduced with increasing diversity due to lower competency of alternative hosts. We found evidence for pathogen dilution, whereby disease risk was lower in sites with higher species diversity, after accounting for potentially confounding effects of host density and landscape heterogeneity. Our results suggest that although nearly all plants in the ecosystem are hosts, alternative hosts may dilute disease transmission by competent hosts, thereby buffering forest health from infectious disease.

    1987-02-01

    The lubber grasshopper,Romalea guttata, produces a metathoracic defensive secretion containing primarily phenolics and quinones. This insect feeds on a wide range of plant species. Insects reared on an artificial diet and a diet of onion,Allium canadense, had secretions that contained fewer compounds, lower concentrations of compounds, and markedly altered relative composition of components compared to insects reared on a varied diet of 26 plant species that included onion. The study demonstrates that diet breadth has a major effect on the quality and quantity of the autogenous defensive secretion of this generalist herbivore. The results are compared to diet effects known in chemically defended specialists. Two possible mechanisms explaining the effects of diet breadth are proposed: one involves changes in precursor availability with changing diet breadth; the other suggests that physiological stress due to diet restriction changes allocation of resources to chemical defense.

    The training in orthopedic and trauma surgery has changed significantly with the introduction of the new residency program. The contents taught have already been reduced in breadth and the current developments in the outpatient and particularly in the clinical landscape also contribute to increasing specialization. This trend favors structures in which comprehensive medical care for the population in Germany in orthopedic and trauma surgery appears to be endangered and in which the future efforts for e.g. polytraumatised patients need to be questioned. The Young Forum of the German Society for Orthopedics and Traumatology actively accompanies a discussion about the necessity and value of generalists to ensure the level of care in Germany in addition to the specialists.

  19. Bird communities of the arctic shrub tundra of Yamal: habitat specialists and generalists.

    Directory of Open Access Journals (Sweden)

    Vasiliy Sokolov

    Full Text Available BACKGROUND: The ratio of habitat generalists to specialists in birds has been suggested as a good indicator of ecosystem changes due to e.g. climate change and other anthropogenic perturbations. Most studies focusing on this functional component of biodiversity originate, however, from temperate regions. The Eurasian Arctic tundra is currently experiencing an unprecedented combination of climate change, change in grazing pressure by domestic reindeer and growing human activity. METHODOLOGY/PRINCIPAL FINDINGS: Here we monitored bird communities in a tundra landscape harbouring shrub and open habitats in order to analyse bird habitat relationships and quantify habitat specialization. We used ordination methods to analyse habitat associations and estimated the proportions of specialists in each of the main habitats. Correspondence Analysis identified three main bird communities, inhabiting upland, lowland and dense willow shrubs. We documented a stable structure of communities despite large multiannual variations of bird density (from 90 to 175 pairs/km(2. Willow shrub thickets were a hotspot for bird density, but not for species richness. The thickets hosted many specialized species whose main distribution area was south of the tundra. CONCLUSION/SIGNIFICANCE: If current arctic changes result in a shrubification of the landscape as many studies suggested, we would expect an increase in the overall bird abundance together with an increase of local specialists, since they are associated with willow thickets. The majority of these species have a southern origin and their increase in abundance would represent a strengthening of the boreal component in the southern tundra, perhaps at the expense of species typical of the subarctic zone, which appear to be generalists within this zone.

    Background The ratio of habitat generalists to specialists in birds has been suggested as a good indicator of ecosystem changes due to e.g. climate change and other anthropogenic perturbations. Most studies focusing on this functional component of biodiversity originate, however, from temperate regions. The Eurasian Arctic tundra is currently experiencing an unprecedented combination of climate change, change in grazing pressure by domestic reindeer and growing human activity. Methodology/Principal Findings Here we monitored bird communities in a tundra landscape harbouring shrub and open habitats in order to analyse bird habitat relationships and quantify habitat specialization. We used ordination methods to analyse habitat associations and estimated the proportions of specialists in each of the main habitats. Correspondence Analysis identified three main bird communities, inhabiting upland, lowland and dense willow shrubs. We documented a stable structure of communities despite large multiannual variations of bird density (from 90 to 175 pairs/km2). Willow shrub thickets were a hotspot for bird density, but not for species richness. The thickets hosted many specialized species whose main distribution area was south of the tundra. Conclusion/Significance If current arctic changes result in a shrubification of the landscape as many studies suggested, we would expect an increase in the overall bird abundance together with an increase of local specialists, since they are associated with willow thickets. The majority of these species have a southern origin and their increase in abundance would represent a strengthening of the boreal component in the southern tundra, perhaps at the expense of species typical of the subarctic zone, which appear to be generalists within this zone.

    Ecological theory predicts that generalist predators should damp or suppress long-term periodic fluctuations (cycles) in their prey populations and depress their average densities. However, the magnitude of these impacts is likely to vary depending on the availability of alternative prey species and the nature of ecological mechanisms driving the prey cycles. These multispecies effects can be modeled explicitly if parameterized functions relating prey consumption to prey abundance, and realistic population dynamical models for the prey, are available. These requirements are met by the interaction between the Hen Harrier (Circus cyaneus) and three of its prey species in the United Kingdom, the Meadow Pipit (Anthus pratensis), the field vole (Microtus agrestis), and the Red Grouse (Lagopus lagopus scoticus). We used this system to investigate how the availability of alternative prey and the way in which prey dynamics are modeled might affect the behavior of simple trophic networks. We generated cycles in one of the prey species (Red Grouse) in three different ways: through (1) the interaction between grouse density and macroparasites, (2) the interaction between grouse density and male grouse aggressiveness, and (3) a generic, delayed density-dependent mechanism. Our results confirm that generalist predation can damp or suppress grouse cycles, but only when the densities of alternative prey are low. They also demonstrate that diametrically opposite indirect effects between pairs of prey species can occur together in simple systems. In this case, pipits and grouse are apparent competitors, whereas voles and grouse are apparent facilitators. Finally, we found that the quantitative impacts of the predator on prey density differed among the three models of prey dynamics, and these differences were robust to uncertainty in parameter estimation and environmental stochasticity.

    As forest communities continue to experience interactions between climate change and shifting disturbance regimes, there is an increased need to link ecological understanding to applied management. Limber pine (Pinus flexilis James.), an understudied species of western North America, has been documented to dominate harsh environments and thought to be competitively excluded from mesic environments. An observational study was conducted using the Forest Inventory and Analysis Database (FIAD) to test the competitive exclusion hypothesis across a broad elevational and geographic area within the Intermountain West, USA. We anticipated that competitive exclusion would result in limber pine's absence from mid-elevation forest communities, creating a bi-modal distribution. Using the FIAD database, limber pine was observed to occur with 22 different overstory species, which represents a surprising number of the woody, overstory species commonly observed in the Intermountain West. There were no biologically significant relationships between measures of annual precipitation, annual temperature, or climatic indices (i.e. Ombrothermic Index) and limber pine dominance. Limber pine was observed to be a consistent component of forest communities across elevation classes. Of the plots that contained limber pine regeneration, nearly half did not have a live or dead limber pine in the overstory. However, limber pine regeneration was greater in plots with higher limber pine basal area and higher average annual precipitation. Our results suggest limber pine is an important habitat generalist, playing more than one functional role in forest communities. Generalists, like limber pine, may be increasingly important, as managers are challenged to build resistance and resilience to future conditions in western forests. Additional research is needed to understand how different silvicultural systems can be used to maintain multi-species forest communities.

    Stand diversification is considered a promising management approach to increasing the multifunctionality and ecological stability of forests. However, how tree diversity affects higher trophic levels and their role in regulating forest functioning is not well explored particularly for (sub)tropical regions. We analyzed the effects of tree species richness, community composition, and functional diversity on the abundance, species richness, and beta diversity of important functional groups of herbivores and predators in a large-scale forest biodiversity experiment in south-east China. Tree species richness promoted the abundance, but not the species richness, of the dominant, generalist herbivores (especially, adult leaf chewers), probably through diet mixing effects. In contrast, tree richness did not affect the abundance of more specialized herbivores (larval leaf chewers, sap suckers) or predators (web and hunting spiders), and only increased the species richness of larval chewers. Leaf chemical diversity was unrelated to the arthropod data, and leaf morphological diversity only positively affected oligophagous herbivore and hunting spider abundance. However, richness and abundance of all arthropods showed relationships with community-weighted leaf trait means (CWM). The effects of trait diversity and CWMs probably reflect specific nutritional or habitat requirements. This is supported by the strong effects of tree species composition and CWMs on herbivore and spider beta diversity. Although specialized herbivores are generally assumed to determine herbivore effects in species-rich forests, our study suggests that generalist herbivores can be crucial for trophic interactions. Our results indicate that promoting pest control through stand diversification might require a stronger focus on identifying the best-performing tree species mixtures.

    Full Text Available Herbivore feeding elicits dramatic increases in defenses, most of which require jasmonate (JA signaling, and against which specialist herbivores are thought to be better adapted than generalist herbivores. Unbiased transcriptional analyses of how neonate larvae cope with these induced plant defenses are lacking.We created cDNA microarrays for Manduca sexta and Heliothis virescens separately, by spotting normalized midgut-specific cDNA libraries created from larvae that fed for 24 hours on MeJA-elicited wild-type (WT Nicotiana attenuata plants. These microarrays were hybridized with labeled probes from neonates that fed for 24 hours on WT and isogenic plants progressively silenced in JA-mediated defenses (N: nicotine; N/PI: N and trypsin protease inhibitors; JA: all JA-mediated defenses. H. virescens neonates regulated 16 times more genes than did M. sexta neonates when they fed on plants silenced in JA-mediated defenses, and for both species, the greater the number of defenses silenced in the host plant (JA > N/PI > N, the greater were the number of transcripts regulated in the larvae. M. sexta larvae tended to down-regulate while H. virescens larvae up- and down-regulated transcripts from the same functional categories of genes. M. sexta larvae regulated transcripts in a diet-specific manner, while H. virescens larvae regulated a similar suite of transcripts across all diet types.The observations are consistent with the expectation that specialists are better adapted than generalist herbivores to the defense responses elicited in their host plants by their feeding. While M. sexta larvae appear to be better adapted to N. attenuata's defenses, some of the elicited responses remain effective defenses against both herbivore species. The regulated genes provide novel insights into larval adaptations to N. attenuata's induced defenses, and represent potential targets for plant-mediated RNAi to falsify hypotheses about the process of adaptation.

    The ecological impacts of generalist herbivores depend on feeding preferences, which can vary across and within herbivore species. Among mesoherbivores, geographic variation in host use can occur because host plants have a more restricted geographic distribution than does the herbivore, or there is local evolution in host preference, or both. We tested the role of local evolution using the marine amphipod Ampithoe longimana by rearing multiple amphipod populations from three regions (subtropical Florida, warm-temperate North Carolina and cold-temperate New England) and assaying their feeding preferences toward ten seaweeds that occur in some but not all regions. Six of the ten seaweeds produce anti-herbivore secondary metabolites, and we detected geographic variation in feeding preference toward five (Dictyota menstrualis, Dictyota ciliolata, Fucus distichus, Chondrus crispus and Padina gymnospora, but not Caulerpa sertularioides). Amphipod populations that co-occur with a chemically-rich seaweed tended to have stronger feeding preferences for that seaweed, relative to populations that do not co-occur with the seaweed. A direct test indicated that geographic variation in feeding preference toward one seaweed (D. ciliolata) is mediated by feeding tolerance for lipophilic secondary metabolites. Among the four seaweeds that produce no known secondary metabolites (Acanthophora, Ectocarpus, Gracilaria and Hincksia/Feldmannia spp.), we detected no geographic variation in feeding preference. Thus, populations are more likely to evolve greater feeding preferences for local hosts when those hosts produce secondary metabolites. Microevolution of feeding behaviors of generalist marine consumers likely depends on the availability and identity of local hosts and the strength of their chemical defenses.

  8. Non proliferation regimes undertakings: Benefits and limits of synergies in verification technologies and procedures

    Richard, M.

    2001-01-01

    Full text: Thirty years ago the NPT was entering into force. Therewith, when a State became party to the NPT, it had, in accordance with article III.1 of the Treaty, an undertaking to conclude a Comprehensive Safeguards agreement with the IAEA and accept safeguards verification on source or special fissionable material in all peaceful nuclear activities within its territories in order to verify that such material is not diverted. This multilateral instrument was the foundation stone of the non-proliferation regime and marked the actual birth of internationally accepted measures to verily compliance with politically stringent agreements. Since that time several important multilateral or bilateral instruments on non-proliferation and disarmament have been negotiated and adopted to curb the development and the acquisition of Weapons of Mass Destruction (WMD) most of them since the middle of the eighties and the collapse of the Soviet Union. Amongst the multilateral instruments are the Convention on the Prohibition of Bacteriological Weapon and Toxin Weapons (1972), the Convention on the Prohibition of Chemical Weapons (1993), the Comprehensive Test Ban Treaty (1996), the Strengthening of the IAEA Safeguards and the Additional Protocol (1997), with some still in negotiation like the Protocol of the Convention on the Prohibition of Bacteriological and Toxin Weapons, and some on which negotiation is still a wish like the Fissile Material Cut-off Treaty. Bilateral disarmament agreements between the United States of America and the Russian Federation such as the INF Treaty, START I and II, the agreements on the elimination of excess defence nuclear material as well as the Trilateral Initiative with the IAEA pave the way to nuclear disarmament with the reduction of both the number of nuclear weapons arsenal and the fissile material inventories.

  10. Verifying compliance with nuclear non-proliferation undertakings: IAEA safeguards agreements and additional protocols

    International Nuclear Information System (INIS)

    2008-06-01

    This report provides background information on safeguards and explains procedures for States to conclude Additional Protocols to comprehensive Safeguards Agreements with the IAEA. Since the IAEA was founded in 1957, its safeguards system has been an indispensable component of the nuclear non-proliferation regime and has facilitated peaceful nuclear cooperation. In recognition of this, the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) makes it mandatory for all non-nuclear-weapon States (NNWS) party to the Treaty to conclude comprehensive safeguards agreements with the IAEA, and thus allow for the application of safeguards to all their nuclear material. Under Article III of the NPT, all NNWS undertake to accept safeguards, as set forth in agreements to be negotiated and concluded with the IAEA, for the exclusive purpose of verification of the fulfilment of the States' obligations under the NPT. In May 1997, the IAEA Board of Governors approved the Model Additional Protocol to Safeguards Agreements (reproduced in INFCIRC/540(Corr.)) which provided for an additional legal authority. In States that have both a comprehensive safeguards agreement and an additional protocol in force, the IAEA is able to optimize the implementation of all safeguards measures available. In order to simplify certain procedures under comprehensive safeguards agreements for States with little or no nuclear material and no nuclear material in a facility, the IAEA began making available, in 1971, a 'small quantities protocol' (SQP), which held in abeyance the implementation of most of the detailed provisions of comprehensive safeguards agreements for so long as the State concerned satisfied these criteria. The safeguards system aims at detecting and deterring the diversion of nuclear material. Such material includes enriched uranium, plutonium and uranium-233, which could be used directly in nuclear weapons. It also includes natural uranium and depleted uranium, the latter of which is

    This research investigates farmers' cognitive perceptions of risk and the behavioral intentions to undertake farm-level risk-reduction measures. It has been observed that people who are susceptible to natural hazards often fail to act, or do very little, to protect their assets or lives. To answer the question of why some people show adaptive behavior while others do not, a socio-psychological model of precautionary adaptation based on protection motivation theory and trans-theoretical stage model has been applied for the first time to areas of drought risk in the developing countries cultural context. The applicability of the integrated model is explored by means of a representative sample survey of smallholder farmers in northern Ethiopia. The result of the study showed that there is a statistically significant association between farmer's behavioral intention to undertake farm-level risk-reduction measures and the main important protection motivation model variables. High perceived vulnerability, severity of consequences, self-efficacy, and response efficacy lead to higher levels of behavioral intentions to undertake farm-level risk-reduction measures. For farmers in the action stage, self-efficacy and response efficacy were the main motivators of behavioral intention. For farmers in the contemplative stage, self-efficacy and cost appear to be the main motivators for them to act upon risk reduction, while perceived severity of consequences and cost of response actions were found to be important for farmers in the pre-contemplative stage.

    This case-study compared traditional, face-to-face classroom-based teaching with asynchronous online learning and teaching methods in two sets of students undertaking a problem-based learning module in the multilevel and exploratory factor analysis of longitudinal data as part of a Masters degree in Public Health at Maastricht University. Students were allocated to one of the two study variants on the basis of their enrolment status as full-time or part-time students. Full-time students (n = 11) followed the classroom-based variant and part-time students (n = 12) followed the online asynchronous variant which included video recorded lectures and a series of asynchronous online group or individual SPSS activities with synchronous tutor feedback. A validated student motivation questionnaire was administered to both groups of students at the start of the study and a second questionnaire was administered at the end of the module. This elicited data about student satisfaction with the module content, teaching and learning methods, and tutor feedback. The module coordinator and problem-based learning tutor were also interviewed about their experience of delivering the experimental online variant and asked to evaluate its success in relation to student attainment of the module's learning outcomes. Student examination results were also compared between the two groups. Asynchronous online teaching and learning methods proved to be an acceptable alternative to classroom-based teaching for both students and staff. Educational outcomes were similar for both groups, but importantly, there was no evidence that the asynchronous online delivery of module content disadvantaged part-time students in comparison to their full-time counterparts.

    The health of adolescents is increasingly seen as an important international priority because the world's one point eight billion young people (aged 10 to 24 years) accounts for 15.5% of the global burden of disease and are disproportionately located in low- and middle-income countries (LMICs). Furthermore, an estimated 70% of premature adult deaths are attributable to unhealthy behaviors often initiated in adolescence (such as smoking, obesity, and physical inactivity). In order for health services to reach adolescents in LMICs, innovative service delivery models need to be explored and tested. This paper reviews the literature on generalist and specialist community health workers (CHWs) to assess their potential for strengthening the delivery of adolescent health services. We reviewed the literature on CHWs using Medline (PubMed), EBSCO Global Health, and Global Health Archive. Search terms (n = 19) were sourced from various review articles and combined with subject heading 'sub-Saharan Africa' to identify English language abstracts of original research articles on generalist and specialist CHWs. A total of 106 articles, from 1985 to 2012, and representing 24 African countries, matched our search criteria. A single study in sub-Saharan Africa used CHWs to deliver adolescent health services with promising results. Though few comprehensive evaluations of large-scale CHW programs exist, we found mixed evidence to support the use of either generalist or specialist CHW models for delivering adolescent health services. This review found that innovative service delivery approaches, such as those potentially offered by CHWs, for adolescents in sub-Saharan Africa are lacking, CHW programs have proliferated despite the absence of high quality evaluations, rigorous studies to establish the comparative effectiveness of generalist versus specialist CHW programs are needed, and further investigation of the role of CHWs in providing adolescent health services in sub

    Theoretically, homogeneous environments favor the evolution of specialists whereas heterogeneous environments favor generalists. Canine distemper is a multi-host carnivore disease caused by canine distemper virus (CDV). The described cell receptor of CDV is SLAM (CD150). Attachment of CDV hemagglutinin protein (CDV-H) to this receptor facilitates fusion and virus entry in cooperation with the fusion protein (CDV-F). We investigated whether CDV strains co-evolved in the large, homogeneous domestic dog population exhibited specialist traits, and strains adapted to the heterogeneous environment of smaller populations of different carnivores exhibited generalist traits. Comparison of amino acid sequences of the SLAM binding region revealed higher similarity between sequences from Canidae species than to sequences from other carnivore families. Using an in vitro assay, we quantified syncytia formation mediated by CDV-H proteins from dog and non-dog CDV strains in cells expressing dog, lion or cat SLAM. CDV-H proteins from dog strains produced significantly higher values with cells expressing dog SLAM than with cells expressing lion or cat SLAM. CDV-H proteins from strains of non-dog species produced similar values in all three cell types, but lower values in cells expressing dog SLAM than the values obtained for CDV-H proteins from dog strains. By experimentally changing one amino acid (Y549H) in the CDV-H protein of one dog strain we decreased expression of specialist traits and increased expression of generalist traits, thereby confirming its functional importance. A virus titer assay demonstrated that dog strains produced higher titers in cells expressing dog SLAM than cells expressing SLAM of non-dog hosts, which suggested possible fitness benefits of specialization post-cell entry.

    Full Text Available The Sclerotiniaceae (Ascomycotina, Leotiomycetes is a relatively recently evolved lineage of necrotrophic host generalists, and necrotrophic or biotrophic host specialists, some latent or symptomless. We hypothesized that they inherited a basic toolbox of genes for plant symbiosis from their common ancestor. Maintenance and evolutionary diversification of symbiosis could require selection on toolbox genes or on timing and magnitude of gene expression. The genes studied were chosen because their products have been previously investigated as pathogenicity factors in the Sclerotiniaceae. They encode proteins associated with cell wall degradation: acid protease 1 (acp1, aspartyl protease (asps, and polygalacturonases (pg1, pg3, pg5, pg6, and the oxalic acid (OA pathway: a zinc finger transcription factor (pac1, and oxaloacetate acetylhydrolase (oah, catalyst in OA production, essential for full symptom production in Sclerotinia sclerotiorum. Site-specific likelihood analyses provided evidence for purifying selection in all 8 pathogenicity-related genes. Consistent with an evolutionary arms race model, positive selection was detected in 5 of 8 genes. Only generalists produced large, proliferating disease lesions on excised Arabidopsis thaliana leaves and oxalic acid by 72 hours in vitro. In planta expression of oah was 10-300 times greater among the necrotrophic host generalists than necrotrophic and biotrophic host specialists; pac1 was not differentially expressed. Ability to amplify 6/8 pathogenicity related genes and produce oxalic acid in all genera are consistent with the common toolbox hypothesis for this gene sample. That our data did not distinguish biotrophs from necrotrophs is consistent with 1 a common toolbox based on necrotrophy and 2 the most conservative interpretation of the 3-locus housekeeping gene phylogeny--a baseline of necrotrophy from which forms of biotrophy emerged at least twice. Early oah overexpression likely expands the

    The Generalist Genes Hypothesis is based upon quantitative genetic findings which indicate that many of the same genes influence diverse cognitive abilities and disabilities across age. In a recent genome-wide association study of mathematical ability in 10-year-old children, 43 SNP associations were nominated from scans of pooled DNA, 10 of which were validated in an individually genotyped sample. The 4927 children in this genotyped sample have also been studied at 7, 9 and 12 years of age on measures of mathematical ability, as well as on other cognitive and learning abilities. Using these data we have explored the Generalist Genes Hypothesis by assessing the association of the available measures of ability at age 10 and other ages with two composite 'SNP-set' scores, formed from the full set of 43 nominated SNPs and the sub-set of 10 SNPs that were previously found to be associated with mathematical ability at age 10. Both SNP sets yielded significant associations with mathematical ability at ages 7, 9 and 12, as well as with reading and general cognitive ability at age 10. Although effect sizes are small, our results correspond with those of quantitative genetic research in supporting the Generalist Genes Hypothesis. SNP sets identified on the basis of their associations with mathematical ability at age 10 show associations with mathematical ability at earlier and later ages and show associations of similar magnitude with reading and general cognitive ability. With small effect sizes expected in such complex traits, future studies may be able to capitalise on power by searching for 'generalist genes' using longitudinal and multivariate approaches.

  2. Reconsidering the specialist-generalist paradigm in niche breadth dynamics: resource gradient selection by Canada lynx and bobcat.

    Directory of Open Access Journals (Sweden)

    Michael J L Peers

    Full Text Available The long-standing view in ecology is that disparity in overall resource selection is the basis for identifying niche breadth patterns, with species having narrow selection being classified "specialists" and those with broader selection being "generalists". The standard model of niche breadth characterizes generalists and specialists as having comparable levels of overall total resource exploitation, with specialists exploiting resources at a higher level of performance over a narrower range of conditions. This view has gone largely unchallenged. An alternate model predicts total resource use being lower for the specialized species with both peaking at a comparable level of performance over a particular resource gradient. To reconcile the niche breadth paradigm we contrasted both models by developing range-wide species distribution models for Canada lynx, Lynx canadensis, and bobcat, Lynx rufus. Using a suite of environmental factors to define each species' niche, we determined that Canada lynx demonstrated higher total performance over a restricted set of variables, specifically those related to snow and altitude, while bobcat had higher total performance across most variables. Unlike predictions generated by the standard model, bobcat level of exploitation was not compromised by the trade-off with peak performance, and Canada lynx were not restricted to exploiting a narrower range of conditions. Instead, the emergent pattern was that specialist species have a higher total resource utilization and peak performance value within a smaller number of resources or environmental axes than generalists. Our results also indicate that relative differences in niche breadth are strongly dependent on the variable under consideration, implying that the appropriate model describing niche breadth dynamics between specialists and generalists may be more complex than either the traditional heuristic or our modified version. Our results demonstrate a need to re

    Specialist and generalist life histories are expected to result in contrasting levels of genetic diversity at the population level, and symbioses are expected to lead to patterns that reflect a shared biogeographic history and co-diversification. We test these assumptions using mtDNA sequencing and a comparative phylogeographic approach for six co-occurring crustacean species that are symbiotic with sea anemones on western Atlantic coral reefs, yet vary in their host specificities: four are host specialists and two are host generalists. We first conducted species discovery analyses to delimit cryptic lineages, followed by classic population genetic diversity analyses for each delimited taxon, and then reconstructed the demographic history for each taxon using traditional summary statistics, Bayesian skyline plots, and approximate Bayesian computation to test for signatures of recent and concerted population expansion. The genetic diversity values recovered here contravene the expectations of the specialist-generalist variation hypothesis and classic population genetics theory; all specialist lineages had greater genetic diversity than generalists. Demography suggests recent population expansions in all taxa, although Bayesian skyline plots and approximate Bayesian computation suggest the timing and magnitude of these events were idiosyncratic. These results do not meet the a priori expectation of concordance among symbiotic taxa and suggest that intrinsic aspects of species biology may contribute more to phylogeographic history than extrinsic forces that shape whole communities. The recovery of two cryptic specialist lineages adds an additional layer of biodiversity to this symbiosis and contributes to an emerging pattern of cryptic speciation in the specialist taxa. Our results underscore the differences in the evolutionary processes acting on marine systems from the terrestrial processes that often drive theory. Finally, we continue to highlight the Florida Reef

    Species endemic to the tropical regions are expected to be vulnerable to future climate change due in part to their relatively narrow climatic niches. In addition, these species are more likely to have responded strongly to past climatic change, and this can be explored through phylogeographic analyses. To test the hypothesis that tropical specialists are more sensitive to climate change than climate generalists, we generated and analyse sequence data from mtDNA and ~2500 exons to compare scales of historical persistence and population fluctuation in two sister species of Australian rainbow skinks: the tropical specialist Carlia johnstonei and the climate generalist C. triacantha. We expect the tropical specialist species to have deeper and finer-scale phylogeographic structure and stronger demographic fluctuations relative to the closely related climate generalist species, which should have had more stable populations through periods of harsh climate in the late Quaternary. Within C. johnstonei, we find that some populations from the northern Kimberley islands are highly divergent from mainland populations. In C. triacantha, one major clade occurs across the deserts and into the mesic Top End, and another occurs primarily in the Kimberley with scattered records eastwards. Where their ranges overlap in the Kimberley, both mitochondrial DNA and nuclear DNA suggest stronger phylogeographic structure and range expansion within the tropical specialist, whereas the climate generalist has minimal structuring and no evidence of recent past range expansion. These results are consistent with the hypothesis that tropical specialists are more sensitive to past climatic change. © 2017 John Wiley & Sons Ltd.

  5. Testing the diet-breadth trade-off hypothesis: differential regulation of novel plant secondary compounds by a specialist and a generalist herbivore.

    Specialist herbivores are predicted to have evolved biotransformation pathways that can process large doses of secondary compounds from the plant species on which they specialize. It is hypothesized that this physiological specialization results in a trade-off such that specialists may be limited in ability to ingest novel plant secondary compounds (PSCs). In contrast, the generalist foraging strategy requires that herbivores alternate consumption of plant species and PSC types to reduce the possibility of over-ingestion of any particular PSC. The ability to behaviorally regulate is a key component of this strategy. These ideas underpin the prediction that in the face of novel PSCs, generalists should be better able to maintain body mass and avoid toxic consequences compared to specialists. We explored these predictions by comparing the feeding behavior of two herbivorous rodents: a juniper specialist, Neotoma stephensi, and a generalist, Neotoma albigula, fed diets with increasing concentrations of phenolic resin extracted from the creosote bush (Larrea tridentata), which produces a suite of PSCs novel to both species. The specialist lost more mass than the generalist during the 15-day trial. In addition, although the specialist and generalist both regulated phenolic resin intake by reducing meal size while on the highest resin concentration (4%), the generalist began to regulate intake on the 2% diet. The ability of the generalist to regulate intake at a lower PSC concentration may be the source of the generalist's performance advantage over the specialist. These data provide evidence for the hypothesis that the specialist's foraging strategy may result in behavioral as well as physiological trade-offs in the ability to consume novel PSCs.

  6. Implications of staff 'churn' for nurse managers, staff, and patients.

    In this article, the term "churn" is used not only because of the degree of change to staffing, but also because some of the reasons for staff movement are not classified as voluntary turnover. The difficulties for the nurse managing a unit with the degree of "churn" should not be under-estimated. Changes to skill mix and the proportions of full-time, agency, and temporary staff present challenges in providing clinical leadership, scheduling staff, performance management, and supervision. Perhaps more importantly, it is likely that there is an impact on the continuity of care provided in the absence of continuity of staffing. A greater understanding of the human and financial costs and consequences, and a willingness to change established practices at the institutional and ward level, are needed.

    Optimal habitat selection is essential for species survival in ecosystems, and interspecific competition is a key ecological mechanism for many observed species association patterns. Specialized animal species are commonly affected by resource and interference competition with generalist and/or omnivorous competitors, so avoidance behavior could be expected. We hypothesize that specialist species may exploit broad range cues from such potential resource competitors (i.e., cues possibly common to various generalist and/or omnivorous predators) to avoid costly competition regarding food or reproduction, even in new species associations. We tested this hypothesis by studying short-term interactions between a native larval parasitoid and a native generalist omnivorous predator recently sharing the same invasive host/prey, the leaf miner Tuta absoluta. We observed a strong negative effect of kleptoparasitism (food resource stealing) instead of classical intraguild predation on immature parasitoids. There was no evidence that parasitoid females avoided the omnivorous predator when searching for oviposition sites, although we studied both long- and short-range known detection mechanisms. Therefore, we conclude that broad range cue avoidance may not exist in our biological system, probably because it would lead to too much oviposition site avoidance which would not be an efficient and, thus, beneficial strategy. If confirmed in other parasitoids or specialist predators, our findings may have implications for population dynamics, especially in the current context of increasing invasive species and the resulting creation of many new species associations.

    The aerial environment is heterogeneous in space and time and directly influences the costs of animal flight. Volant animals can reduce these costs by using different flight modes, each with their own benefits and constraints. However, the extent to which animals alter their flight modes in response to environmental conditions has rarely been studied in the wild. To provide insight into how a flight generalist can reduce the energetic cost of movement, we studied flight behaviour in relation to the aerial environmental and landscape using hundreds of hours of global positioning system and triaxial acceleration measurements of the lesser black-backed gull (Larus fuscus). Individuals differed largely in the time spent in flight, which increased linearly with the time spent in flight at sea. In general, flapping was used more frequently than more energetically efficient soaring flight. The probability of soaring increased with increasing boundary layer height and time closer to midday, reflecting improved convective conditions supportive of thermal soaring. Other forms of soaring flight were also used, including fine-scale use of orographic lift. We explore the energetic consequences of behavioural adaptations to the aerial environment and underlying landscape and implications for individual energy budgets, foraging ecology and reproductive success.This article is part of the themed issue 'Moving in a moving medium: new perspectives on flight'. © 2016 The Author(s).

    What happens when an exotic herbivore invades and encounters novel host plants and enemies? Here, we investigate the impacts of host plant quality and plant architecture on an exotic generalist herbivore, Epiphyas postvittana (Lepidoptera: Tortricidae) and its interactions with resident parasitoids in California. Using artificial diet and five plant species, we found significant effects of diet on the fitness of E. postvittana under laboratory conditions. In the field, based on a common garden experiment with host plants of nine species, we found that larval parasitism varied among plant species by a factor of 2.1 with a higher risk of parasitism on shorter than taller plants. Parasitism of egg masses varied by a factor of 4.7 among plant species with a higher risk of parasitism on taller than shorter plants. In the laboratory, the foraging time of a resident egg parasitoid on excised leaves varied among plant species, but did not correspond to observed egg parasitism rates on these same plants in the field. On leaves of Plantago lanceolata, the probability of egg parasitism decreased with trichome density. Overall, there was a significant effect of host plant on the intrinsic rate of increase of E. postvittana and on the extent of parasitism by resident parasitoids, but no correlation existed between these two effects. The recent decline of E. postvittana in California may be due to the low quality of some host plants and to the many resident enemies that readily attack it, perhaps due to its phylogenetic relatedness to resident tortricids.

    Understanding which factors influence the invasion of alien seaweed has become a central concern in ecology. Increasing evidence suggests that the feeding preferences of native herbivores influence the success of alien seaweeds in the new community. We investigated food selection of a generalist native grazer Paracentrotus lividus, in the presence of two alien seaweeds (Caulerpa cylindracea and Caulerpa taxifolia var. distichophylla) and two native seaweeds (Dictyopteris membranacea and Cystoseira compressa). Sea urchins were fed with six experimental food items: C. cylindracea, C. taxifolia var. distichophylla, a mixture of C. cylindracea and C. taxifolia var. distichophylla, D. membranacea, C. compressa and a mixture of D. membranacea and C. compressa. P. lividus ingested all the combinations of food offered, though it preferentially consumed the alien mixture, C. cylindracea and D. membranacea. The alien C. taxifolia var. distichophylla was consumed significantly less than the other food items and, interestingly, it was ingested in a greater amount when mixed with C. cylindracea than when on its own. This finding suggests that C. taxifolia var. distichophylla may become vulnerable to sea urchin grazing when it grows intermingled with C. cylindracea, which does not gain immediate protection from the presence of the very low palatable congeneric seaweed. The present study highlights the potential role of native grazers to indirectly affect the interspecific competition between the two alien seaweeds in the Mediterranean Sea.

    The diversity and specificity of microbial communities in marine environments is a key aspect of the ecology and evolution of both the eukaryotic hosts and their associated prokaryotes. Marine sponges harbor phylogenetically diverse and complex microbial lineages. Here, we investigated the sponge bacterial community and distribution patterns of microbes in three sympatric intertidal marine demosponges, Hymeniacidon perlevis, Ophlitaspongia papilla and Polymastia penicillus, from the Atlantic coast of Portugal using classical isolation techniques and 16S rRNA gene clone libraries. Microbial composition assessment, with nearly full-length 16S rRNA gene sequences (ca. 1400 bp) from the isolates (n = 31) and partial sequences (ca. 280 bp) from clone libraries (n = 349), revealed diverse bacterial communities and other sponge-associated microbes. The majority of the bacterial isolates were members of the order Vibrionales and other symbiotic bacteria like Pseudovibrio ascidiaceiocola, Roseobacter sp., Hahellaceae sp. and Cobetia sp. Extended analyses using ecological metrics comprising 142 OTUs supported the clear differentiation of bacterial community profiles among the sponge hosts and their ambient seawater. Phylogenetic analyses were insightful in defining clades representing shared bacterial communities, particularly between H. perlevis and the geographically distantly-related H. heliophila, but also among other sponges. Furthermore, we also observed three distinct and unique bacterial groups, Betaproteobactria (~81%), Spirochaetes (~7%) and Chloroflexi (~3%), which are strictly maintained in low-microbial-abundance host species O. papilla and P. penicillus. Our study revealed the largely generalist nature of microbial associations among these co-occurring intertidal marine sponges.

    Generalist insect predators play an essential role in regulating the populations of Bemisia tabaci and other pests in agricultural systems, but may be affected negatively by insecticides applied for pest management. Evaluation of insecticide compatibility with specific predator species can provide a basis for making treatment decisions with the aim of conserving natural enemies. Eleven insecticides representing six modes of action groups were evaluated for toxicity against four predator species and at different developmental stages. Full-concentration series bioassays were conducted on laboratory-reared or insectary-supplied predators using Petri dish and systemic uptake bioassay techniques. Highest toxicities were observed with imidacloprid and clothianidin against first and second instar nymphs of Geocoris punctipes (Say) (Hemiptera: Geocoridae). Later instar nymphs were less susceptible to neonicotinoid treatments based on higher LC50s observed with imidacloprid, thiamethoxam, and dinotefuran against third or fourth instar nymphs. The pyrethroid insecticide bifenthrin was highly toxic against adults of G. punctipes and Orius insidiosus (Say) (Hemiptera: Anthocoridae). Standard concentration/mortality evaluation of nonacute toxicity insecticides, including buprofezin, pyriproxyfen, spirotetramat, and spiromesifen, was inconclusive in terms of generating probit statistics. However, low mortality levels of insects exposed for up to 120 h suggested minimal lethality with the exception of pyriproxyfen that was mildly toxic to Chrysoperla rufilabris (Burmeister) (Neuroptera: Chrysopidae).

    Insect herbivores exhibit various strategies to counter the toxic effects of plant chemical defenses. These strategies include the detoxification, excretion, and sequestration of plant secondary metabolites. The latter strategy is often considered to provide an additional benefit in that it provides herbivores with protection against natural enemies such as predators. Profiles of sequestered chemicals are influenced by the food plants from which these chemicals are derived. We compared the effects of sequestration and nonsequestration of plant secondary metabolites in two specialist herbivores on the development of a generalist predator, Podisus maculiventris. Profiles of glucosinolates, secondary metabolites characteristic for the Brassicaceae, are known to differ considerably both inter- and intraspecifically. Throughout their immature (=nymphal) development, the predator was fed on larval stages of either sequestering (turnip sawfly, Athalia rosae) or nonsequestering (small cabbage white butterfly, Pieris rapae) prey that in turn had been feeding on plants originating from three wild cabbage ( Brassica oleracea) populations that have previously been shown to differ in their glucosinolate profiles. We compared survival, development time, and adult body mass as parameters for bug performance. Our results show that sequestration of glucosinolates by A. rosae only marginally affected the development of P. maculiventris. The effects of plant population on predator performance were variable. We suggest that sequestration of glucosinolates by A. rosae functions not only as a defensive mechanism against some predators, but may also be an alternative way of harmlessly dealing with plant allelochemicals.

    Desert ungulates live in adverse ecosystems that are particularly sensitive to degradation and global climate change. Here, we asked how two ungulate species with contrasting feeding habits, grazing gemsbok (Oryx g. gazella) and browsing springbok (Antidorcas marsupialis), respond to an increase in food availability during a pronounced rain period. We used a stable isotope approach to delineate the feeding habits of these two ungulates in the arid Kunene Region of Namibia. Our nineteen months field investigation included two time periods of drought when food availability for ungulates was lowest and an intermediate period with extreme, unusual rainfalls. We documented thirteen isotopically distinct food sources in the isotopic space of the study area. Our results indicated a relatively high dietary plasticity of gemsbok, which fed on a mixture of plants, including more than 30% of C3 plants during drought periods, but almost exclusively on C4 and CAM plant types when food was plentiful. During drought periods, the inferred gemsbok diets also consisted of up to 25% of Euphorbia damarana; an endemic CAM plant that is rich in toxic secondary plant compounds. In contrast, springbok were generalists, feeding on a higher proportion of C3 than C4/CAM plants, irrespective of environmental conditions. Our results illustrate two dietary strategies in gemsbok and springbok which enable them to survive and coexist in the hostile Kunene arid ecosystem.

    Host traits and phylogeny can determine infection risk by driving pathogen transmission and its ability to infect new hosts. Predicting such risks is critical when designing disease mitigation strategies, and especially as regards wildlife, where intensive management is often advocated or prevented by economic and/or practical reasons. We investigated Pseudogymnoascus [Geomyces] destructans infection, the cause of white-nose syndrome (WNS), in relation to chiropteran ecology, behaviour and phylogenetics. While this fungus has caused devastating declines in North American bat populations, there have been no apparent population changes attributable to the disease in Europe. We screened 276 bats of 15 species from hibernacula in the Czech Republic over 2012 and 2013, and provided histopathological evidence for 11 European species positive for WNS. With the exception of Myotis myotis, the other ten species are all new reports for WNS in Europe. Of these, M. emarginatus, Eptesicus nilssonii, Rhinolophus hipposideros, Barbastella barbastellus and Plecotus auritus are new to the list of P. destructans-infected bat species. While the infected species are all statistically phylogenetically related, WNS affects bats from two suborders. These are ecologically diverse and adopt a wide range of hibernating strategies. Occurrence of WNS in distantly related bat species with diverse ecology suggests that the pathogen may be a generalist and that all bats hibernating within the distribution range of P. destructans may be at risk of infection.

    The domestication of crops is among the most important innovations in human history. Here, we test the hypothesis that cultivation and artificial selection for increased productivity of crops reduced plant defenses against herbivores. We compared the performance of two economically important generalist herbivores - the leaf-chewing beet armyworm (Spodoptera exigua) and the phloem-feeding green peach aphid (Myzus persicae) - across 29 crop species and their closely related wild relatives. We also measured putative morphological and chemical defensive traits and correlated them with herbivore performance. We show that, on average, domestication significantly reduced resistance to S. exigua, but not M. persicae, and that most independent domestication events did not cause differences in resistance to either herbivore. In addition, we found that multiple plant traits predicted resistance to S. exigua and M. persicae, and that domestication frequently altered the strength and direction of correlations between these traits and herbivore performance. Our results show that domestication can alter plant defenses, but does not cause strong allocation tradeoffs as predicted by plant defense theory. These results have important implications for understanding the evolutionary ecology of species interactions and for the search for potential resistance traits to be targeted in crop breeding. © 2014 The Authors.

  17. Generalists or Specialists: Stable Isotope Analysis of Humpback Whales (Megapteranoveangliae) to Infer Variation in Feeding Preferences

    2016-02-01

    Though humpback whales (Megapteranovaeangliae) are commonly observed in coastal waters of the Gulf of Alaska, their massive size, behavior, and weather conditionsmake it difficult to make accurate observations regarding their feeding habits. These whales can be highly abundant during feeding aggregations, and given their large energetic needs, they have the potential to impact populations of ecologically important forage such as krill and herring. Previous studies in other areas, such as the Gulf of Maine and the North Pacific Ocean, classify humpback whales as generalists that can efficiently feed on both schooling fish and large zooplankton. In Prince William Sound, scientists have observed the humpbacks feedingprimarily on herring. It is unclear if these whalesfeed exclusively on fish prior to returning to the Sound, and can therefore be considered specialists. Stable isotope analysis of carbon and nitrogen were used to determine the preferred diet of humpback whales (N=22) in 6 sampling regions along the Gulf of Alaska. Isotope analyses were conducted on humpback whale skin, as well as local forage species and basal resources to be used in Bayesian isotope mixing models to elucidate the trophic relationships between whales and their prey, and provide insight to whether location is an important driver in prey selection. This information will not only lead to a better understanding of the potential to use tissue isotopes to elucidate foraging behaviors of humpback whales, but also offer insight into individual feeding preferences and how increasing whale populations may affect the populations of local forage in the future.

    Understanding how biotic communities respond to landscape spatial structure is critically important for conservation management as natural habitats become increasingly fragmented. However, empirical studies of the effects of spatial structure on plant species richness have found inconsistent results, suggesting that more comprehensive approaches are needed. We asked how landscape structure affects total plant species richness and the richness of a guild of specialized plants in a multivariate context. We sampled herbaceous plant communities at 56 dolomite glades (insular, fire-adapted grasslands) across the Missouri Ozarks, USA, and used structural equation modeling (SEM) to analyze the relative importance of landscape structure, soil resource availability, and fire history for plant communities. We found that landscape spatial structure, defined as the area-weighted proximity of glade habitat surrounding study sites (proximity index), had a significant effect on total plant species richness, but only after we controlled for environmental covariates. Richness of specialist species, but not generalists, was positively related to landscape spatial structure. Our results highlight that local environmental filters must be considered to understand the influence of landscape structure on communities and that unique species guilds may respond differently to landscape structure than the community as a whole. These findings suggest that both local environment and landscape context should be considered when developing management strategies for species of conservation concern in fragmented habitats.

  1. Foraging mode affects the evolution of egg size in generalist predators embedded in complex food webs.

    Ecological networks incorporate myriad biotic interactions that determine the selection pressures experienced by the embedded populations. We argue that within food webs, the negative scaling of abundance with body mass and foraging theory predict that the selective advantages of larger egg size should be smaller for sit-and-wait than active-hunting generalist predators, leading to the evolution of a difference in egg size between them. Because body mass usually scales negatively with predator abundance and constrains predation rate, slightly increasing egg mass should simultaneously allow offspring to feed on more prey and escape from more predators. However, the benefits of larger offspring would be relatively smaller for sit-and-wait predators because (i) due to their lower mobility, encounters with other predators are less common, and (ii) they usually employ a set of alternative hunting strategies that help to subdue relatively larger prey. On the other hand, for active predators, which need to confront prey as they find them, body-size differences may be more important in subduing prey. This difference in benefits should lead to the evolution of larger egg sizes in active-hunting relative to sit-and-wait predators.

    Full Text Available Two generalist predators of brown planthopper,Metioche vittaticollis and Anaxipha longipennis (Gryllidae have not been much studied in Indonesia. This research was conducted to study and compare the predatory ability of M. vittaticollis, A. longipennis (Gryllidae and three coleopterans, Paederus fuscipes (Staphylinidae, Ophionea sp. (Carabidae,and Micraspis sp. (Coccinellidae against brown planthopper (fourth and fifth instars under laboratory condition. In total, 20 nymphs of N. lugens were exposed for 2 hour to each predator for 5 consecutive days. Prey consumptions by the predatory crickets, M. vittaticollis and A. longipennis were greater than the other predators and followed by A. longipennis, Micraspis sp., P. fuscipes, and Ophionea sp. respectively. Consumption rates of M. vittaticolis and A. longipenis were also higher than other predators. Micraspis sp was more active on predation in the morning,while M. vittaticollis, A. longipennis, P. fuscipes, and Ophionea sp. were more active both in the morning and the night but not in the afternoon. However, all five species of predators were not so active in preying during the afternoon. In conclusion, a major effort should be extended to conserve these predatory crickets especially M. vittaticollis and A. longipennis.

    The purpose of Technical Staff and Technical Staff Managers training is to provide job skills enhancement to individuals selected to fill key technical positions within a nuclear utility. This training is unique in that unlike other training programs accredited by the National Academy for Nuclear Training, it does not lead to specific task qualification. The problems encountered when determining the student population and curriculum are a direct result of this major difference. Major problems encountered are determining who should attend the training, what amount of training is necessary and sufficient, and how to obtain the best feedback in order to effect substantive program improvements. These topics will be explored and possible solutions discussed

  4. Radiation monitoring of PET staff

    Full text: Positron emission tomography (PET) is becoming a common diagnostic tool in hospitals, often located in and employing staff from the Nuclear Medicine or Radiology departments. Although similar in some ways, staff in PET departments are commonly found to have the highest radiation doses in the hospital environment due to unique challenges which PET tracers present in administration as well as production. The establishment of a PET centre with a dedicated cyclotron has raised concerns of radiation protection to the staff at the WA PET Centre and the Radiopharmaceutical Production and Development (RAPID) team. Since every PET centre has differing designs and practices, it was considered important to closely monitor the radiation dose to our staff so that improvements to practices and design could be made to reduce radiation dose. Electronic dosimeters (MGP DMC 2000XB), which have a facility to log time and dose at 10 second intervals, were provided to three PET technologists and three PET nurses. These were worn in the top pocket of their lab coats throughout a whole day. Each staff member was then asked to note down their duties throughout the day and also note the time they performed each duty. The duties would then correlate with the dose with which the electronic monitor recorded and an estimate of radiation dose per duty could be given. Also an estimate of the dose per day to each staff member could be made. PET nurses averaged approximately 20 μ8v per day getting their largest dose from caring for occasional problematic patients. Smaller doses of a 1-2 μ8v were recorded for injections and removing cannulas. PET technologists averaged approximately 15 μ8v per day getting their largest dose of 1-5μ8v mainly from positioning of patients and sometimes larger doses due to problematic patients. Smaller doses of 1-2 μ5v were again recorded for injections and removal of cannulas. Following a presentation given to staff, all WA PET Centre and RAPID staff

  7. Guidance for nuclear medicine staff on radiopharmaceuticals drug interaction

    International Nuclear Information System (INIS)

    Santos-Oliveira, Ralph

    2009-01-01

    Numerous drug interactions related to radiopharmaceuticals take place every day in hospitals many of which are not reported or detected. Information concerning this kind of reaction is not abundant, and nuclear medicine staff are usually overwhelmed by this information. To better understand this type of reaction, and to help nuclear medicine staff deal with it, a review of the literature was conducted. The results show that almost all of radiopharmaceuticals marketed around the world present drug interactions with a large variety of compounds. This suggests that a logical framework to make decisions based on reviews incorporating adverse reactions must be created. The review also showed that researchers undertaking a review of literature, or even a systematic review that incorporates drug interactions, must understand the rationale for the suggested methods and be able to implement them in their review. Additionally, a global effort should be made to report as many cases of drug interaction with radiopharmaceuticals as possible. With this, a complete picture of drug interactions with radiopharmaceuticals can be drawn. (author)

    2011-07-01

    Full Text Available Abstract Background The principles and practice of Family Medicine that arose in developed Western countries have been imported and adopted in African countries without adequate consideration of their relevance and appropriateness to the African context. In this study we attempted to elicit a priori principles of generalist medical practice from the experience of long-serving medical officers in a variety of African counties, through which we explored emergent principles of Family Medicine in our own context. Methods A descriptive study design was utilized, using qualitative methods. 16 respondents who were clinically active medical practitioners, working as generalists in the public services or non-profit sector for at least 5 years, and who had had no previous formal training or involvement in academic Family Medicine, were purposively selected in 8 different countries in southern, western and east Africa, and interviewed. Results The respondents highlighted a number of key issues with respect to the external environment within which they work, their collective roles, activities and behaviours, as well as the personal values and beliefs that motivate their behaviour. The context is characterized by resource constraints, high workload, traditional health beliefs, and the difficulty of referring patients to the next level of care. Generalist clinicians in sub-Saharan Africa need to be competent across a wide range of clinical disciplines and procedural skills at the level of the district hospital and clinic, in both chronic and emergency care. They need to understand the patient's perspective and context, empowering the patient and building an effective doctor-patient relationship. They are also managers, focused on coordinating and improving the quality of clinical care through teamwork, training and mentoring other health workers in the generalist setting, while being life-long learners themselves. However, their role in the community, was

    To identify variables associated with willingness to undertake leadership roles among academic family medicine faculty. Web-based survey. Bivariate and multivariable analyses (logistic regression) were used to identify variables associated with willingness to undertake leadership roles. Department of Family and Community Medicine at the University of Toronto in Ontario. A total of 687 faculty members. Variables related to respondents' willingness to take on various academic leadership roles. Of all 1029 faculty members invited to participate in the survey, 687 (66.8%) members responded. Of the respondents, 596 (86.8%) indicated their level of willingness to take on various academic leadership roles. Multivariable analysis revealed that the predictors associated with willingness to take on leadership roles were as follows: pursuit of professional development opportunities (odds ratio [OR] 3.79, 95% CI 2.29 to 6.27); currently holding at least 1 leadership role (OR 5.37, 95% CI 3.38 to 8.53); a history of leadership training (OR 1.86, 95% CI 1.25 to 2.78); the perception that mentorship is important for one's current role (OR 2.25, 95% CI 1.40 to 3.60); and younger age (OR 0.97, 95% CI 0.95 to 0.99). Willingness to undertake new or additional leadership roles was associated with 2 variables related to leadership experiences, 2 variables related to perceptions of mentorship and professional development, and 1 demographic variable (younger age). Interventions that support opportunities in these areas might expand the pool and strengthen the academic leadership potential of faculty members.

    This report describes the community context, concept and mission of The Faculty of Medicine at Memorial University of Newfoundland (Memorial), Canada, and its 'pathways to rural practice' approach, which includes influences at the pre-medical school, medical school experience, postgraduate residency training, and physician practice levels. Memorial's pathways to practice helped Memorial to fulfill its social accountability mandate to populate the province with highly skilled rural generalist practitioners. Programs/interventions/initiatives: The 'pathways to rural practice' include initiatives in four stages: (1) before admission to medical school; (2) during undergraduate medical training (medical degree (MD) program); (3) during postgraduate vocational residency training; and (4) after postgraduate vocational residency training. Memorial's Learners & Locations (L&L) database tracks students through these stages. The Aboriginal initiative - the MedQuest program and the admissions process that considers geographic or minority representation in terms of those selecting candidates and the candidates themselves - occurs before the student is admitted. Once a student starts Memorial's MD program, the student has ample opportunities to have rural-based experiences through pre-clerkship and clerkship, of which some take place exclusively outside of St. John's tertiary hospitals. Memorial's postgraduate (PG) Family Medicine (FM) residency (vocational) training program allows for deeper community integration and longer periods of training within the same community, which increases the likelihood of a physician choosing rural family medicine. After postgraduate training, rural physicians were given many opportunities for professional development as well as faculty development opportunities. Each of the programs and initiatives were assessed through geospatial rurality analysis of administrative data collected upon entry into and during the MD program and PG training (L

  1. Acquiring nutrients from tree leaves: effects of leaf maturity and development type on a generalist caterpillar.

    2017-05-01

    The rapid growth and prolific reproduction of many insect herbivores depend on the efficiencies and rates with which they acquire nutrients from their host plants. However, little is known about how nutrient assimilation efficiencies are affected by leaf maturation or how they vary between plant species. Recent work showed that leaf maturation can greatly decrease the protein assimilation efficiency (PAE) of Lymantria dispar caterpillars on some tree species, but not on species in the willow family (Salicaceae). One trait of many species in the Salicaceae that potentially affects PAE is the continuous (or "indeterminate") development of leaves throughout the growing season. To improve our understanding of the temporal and developmental patterns of nutrient availability for tree-feeding insects, this study tested two hypotheses: nutrients (protein and carbohydrate) are more efficiently assimilated from immature than mature leaves, and, following leaf maturation, nutrients are more efficiently assimilated from indeterminate than determinate tree species. The nutritional physiology and growth of a generalist caterpillar (L. dispar) were measured on five determinate and five indeterminate tree species while their leaves were immature and again after they were mature. In support of the first hypothesis, caterpillars that fed on immature leaves had significantly higher PAE and carbohydrate assimilation efficiency (CAE), as well as higher protein assimilation rates and growth rates, than larvae that fed on mature leaves. Contrary to the second hypothesis, caterpillars that fed on mature indeterminate tree leaves did not have higher PAE than those that fed on mature determinate leaves, while CAE differed by only 3% between tree development types. Instead, "high-PAE" and "low-PAE" tree species were found across taxonomic and development categories. The results of this study emphasize the importance of physiological mechanisms, such as nutrient assimilation efficiency, to

    2009-11-01

    Full Text Available Abstract Background The isotopic composition of generalist consumers may be expected to vary in space as a consequence of spatial heterogeneity in isotope ratios, the abundance of resources, and competition. We aim to account for the spatial variation in the carbon and nitrogen isotopic composition of a generalized predatory species across a 500 ha. tropical rain forest landscape. We test competing models to account for relative influence of resources and competitors to the carbon and nitrogen isotopic enrichment of gypsy ants (Aphaenogaster araneoides, taking into account site-specific differences in baseline isotope ratios. Results We found that 75% of the variance in the fraction of 15N in the tissue of A. araneoides was accounted by one environmental parameter, the concentration of soil phosphorus. After taking into account landscape-scale variation in baseline resources, the most parsimonious model indicated that colony growth and leaf litter biomass accounted for nearly all of the variance in the δ15N discrimination factor, whereas the δ13C discrimination factor was most parsimoniously associated with colony size and the rate of leaf litter decomposition. There was no indication that competitor density or diversity accounted for spatial differences in the isotopic composition of gypsy ants. Conclusion Across a 500 ha. landscape, soil phosphorus accounted for spatial variation in baseline nitrogen isotope ratios. The δ15N discrimination factor of a higher order consumer in this food web was structured by bottom-up influences - the quantity and decomposition rate of leaf litter. Stable isotope studies on the trophic biology of consumers may benefit from explicit spatial design to account for edaphic properties that alter the baseline at fine spatial grains.

    Full Text Available Many parasitic nematode species are generalists capable of infecting multiple host species. The complex life cycle of nematodes, involving partial development outside of the host, facilitates transmission of these parasites between host species even when there is no direct contact between hosts. Infective nematode larvae persist in the environment, and where grazing or water sources are shared ingestion of parasite larvae deposited by different host species is likely. In this paper we examine the extent to which nematode parasite species have been observed in sympatric wild and domestic ungulates. First, using existing host–parasite databases, we describe expected overlap of 412 nematode species between 76 wild and 8 domestic ungulate host species. Our results indicate that host-specific parasites make up less than half of the nematode parasites infecting any particular ungulate host species. For wild host species, between 14% (for common warthog and 76% (for mouflon of parasitic nematode species are shared with domestic species. For domestic host species, between 42% (for horse and 77% (for llamas/alpacas of parasitic nematode species are shared with wild species. We also present an index of liability to describe the risk of cross-boundary parasites to each host species. We then examine specific examples from the literature in which transmission of nematode parasites between domestic and wild ungulates is described. However, there are many limitations in the existing data due to geographical bias and certain host species being studied more frequently than others. Although we demonstrate that many species of parasitic nematode are found in both wild and domestic hosts, little work has been done to demonstrate whether transmission is occurring between species or whether similar strains circulate separately. Additional research on cross-species transmission, including the use of models and of genetic methods to define strains, will provide

    2003-03-01

    We studied the nutritional and reproductive response of Poecilus cupreus (synonymous with Pterostichus cupreus), one of the most abundant carabid beetles in arable land, to the succession in sixteen 1- to 4-year-old wildflower areas. A total of 390 male and 373 female beetles was examined. Each female was dissected and the number of ripe eggs counted. The nutritional state was expressed by a condition factor, which was calculated for each individual based on the observed weight and elytra length of male and female P. cupreus. Carabids in the 1-year-old wildflower areas contained significantly less ripe eggs than those from the 4-year-old areas. The condition factor of female and male beetles was significantly lower in 1- than 2- to 4-year-old areas. We examined the influence of habitat parameters (vegetation cover, soil water content, coarse and fine sand, pore volume, habitat size and age, surrounding landscape structure) on the reproductive success and nutritional state of P. cupreus in the 16 wildflower areas. The number of eggs was best explained by habitat age, accounting for 53.4% of the variability. The variation in the condition factor of female and male beetles was best explained by habitat age, which accounted for 73% and 71% of the variation, respectively. Moreover, the beetles' reproductive potential and nutritional condition were significantly associated with vegetation cover, and occasionally also with soil water content. The potential of wildflower areas as a reservoir for the generalist predator P. cupreus was shown to increase with successional age.

  6. Nocturnal herbivore-induced plant volatiles attract the generalist predatory earwig Doru luteipes Scudder

    2017-10-01

    Numerous studies have demonstrated that entomophagous arthropods use herbivore-induced plant volatile (HIPV) blends to search for their prey or host. However, no study has yet focused on the response of nocturnal predators to volatile blends emitted by prey damaged plants. We investigated the olfactory behavioral responses of the night-active generalist predatory earwig Doru luteipes Scudder (Dermaptera: Forficulidae) to diurnal and nocturnal volatile blends emitted by maize plants ( Zea mays) attacked by either a stem borer ( Diatraea saccharalis) or a leaf-chewing caterpillar ( Spodoptera frugiperda), both suitable lepidopteran prey. Additionally, we examined whether the earwig preferred odors emitted from short- or long-term damaged maize. We first determined the earwig diel foraging rhythm and confirmed that D. luteipes is a nocturnal predator. Olfactometer assays showed that during the day, although the earwigs were walking actively, they did not discriminate the volatiles of undamaged maize plants from those of herbivore damaged maize plants. In contrast, at night, earwigs preferred volatiles emitted by maize plants attacked by D. saccharalis or S. frugiperda over undamaged plants and short- over long-term damaged maize. Our GC-MS analysis revealed that short-term damaged nocturnal plant volatile blends were comprised mainly of fatty acid derivatives (i.e., green leaf volatiles), while the long-term damaged plant volatile blend contained mostly terpenoids. We also observed distinct volatile blend composition emitted by maize damaged by the different caterpillars. Our results showed that D. luteipes innately uses nocturnal herbivore-induced plant volatiles to search for prey. Moreover, the attraction of the earwig to short-term damaged plants is likely mediated by fatty acid derivatives.

  7. The education and training needs of health librarians - the generalist versus specialist dilemma.

    2007-09-01

    The aims of the study were to examine whether and how librarians with a generalist background can transfer to roles demanding more expert knowledge in the health sector. The objectives were (i) to compare the education and training needs of health librarians with science degrees with the education and training needs of health librarians with arts and humanities degrees; (ii) to compare the education and training needs of librarians working in the National Health Service (NHS) sector with the education and training needs of librarians working for the health sector but within higher education. Face-to-face interviews with 16 librarians, a convenience sample of librarians working in the Thames Valley NHS region. The main findings confirmed that structured continuing professional development (CPD) is required to meet the rapidly changing needs in the health sector. The emphasis ought to be on teaching skills, outreach work, marketing and promotion, research skills and methods, subject knowledge and terminology, and management skills. Library school curricula do not appear to meet the demands of medical library posts. A first degree in scientific subjects is advantageous in the early stages of a career but diminishes with continuing training and experience. There is no evidence of a significant difference in training needs and provision between the librarians in NHS posts as opposed to those in higher education (HE) posts. The conclusions suggest that library schools need to update their programmes to include teaching skills, advanced search skills, project management skills, research methods, with more practical exercises. Particular attention should be given to librarians with a first degree in non-scientific subjects in terms of time allocated for CPD, quality of training and access to reliable mentorship.

    Environmental contaminants are a concern for animal health, but contaminant exposure can also be used as a tracer of foraging ecology. In particular, mercury (Hg) concentrations are highly variable among aquatic and terrestrial food webs as a result of habitat- and site-specific biogeochemical processes that produce the bioaccumulative form, methylmercury (MeHg). We used stable isotopes and total Hg (THg) concentrations of a generalist consumer, the California gull (Larus californicus), to examine foraging ecology and illustrate the utility of using Hg contamination as an ecological tracer under certain conditions. We identified four main foraging clusters of gulls during pre-breeding and breeding, using a traditional approach based on light stable isotopes. The foraging cluster with the highest δ15N and δ34S values in gulls (cluster 4) had mean blood THg concentrations 614% (pre-breeding) and 250% (breeding) higher than gulls with the lowest isotope values (cluster 1). Using a traditional approach of stable-isotope mixing models, we showed that breeding birds with a higher proportion of garbage in their diet (cluster 2: 63–82% garbage) corresponded to lower THg concentrations and lower δ15N and δ34S values. In contrast, gull clusters with higher THg concentrations, which were more enriched in 15N and 34S isotopes, consumed a higher proportion of more natural, estuarine prey. δ34S values, which change markedly across the terrestrial to marine habitat gradient, were positively correlated with blood THg concentrations in gulls. The linkage we observed between stable isotopes and THg concentrations suggests that Hg contamination can be used as an additional tool for understanding animal foraging across coastal habitat gradients.

    Electronic patient records offer unique opportunities to undertake population-based research. The Health Research Support Service (HRSS) pilot project sought to extract electronic records on a national basis from across health and social care and transfer them together with identifiers to a designated 'safe haven'. To determine the feasibility and acceptability of the HRSS pilot in primary care. Interviews and focus groups with patients and practice staff. There was general support from both patients and staff for the principle of the HRSS. The 'opt-out' basis for participation in the HRSS drew mixed responses from patients and staff, with an appreciation of the advantages in relation to participation by default, but concerns about the extent to which this constituted true consent. Concerns were expressed about confidentiality and the safety and security of the extracted data. The patient information pack was roundly criticized by both patients and staff. Trust in individual GPs, practices and the National Health Service (NHS) was a crucial factor in patients' decisions about participation. Although patients and staff were generally supportive of the HRSS, they require clear information about the proposed use of medical records for research purposes. The question of 'opt out' versus 'opt in' remains controversial and further consideration will be needed if research using routine medical records is to achieve its full potential as a 'core' activity in the NHS.

    Clinical research improves patient care and is a government priority. We sought the opinions of genito-urinary medicine clinic staff regarding undertaking research, any barriers they perceived, and methods to optimise study recruitment. Questionnaires were offered to everyone working in the genito-urinary medicine clinic over a one-week period. In addition, four focus groups were held with genito-urinary medicine clinic staff. Forty-three questionnaires were completed. All respondents stated that research was important; however, 14.0% worried that it affected patient care and 16.3% would rather see patients without having to consider research. Doctors were more likely to enjoy discussing studies than other healthcare staff (p = 0.029) and were less likely to think that too many studies were being conducted at one time (p = 0.027). Forty staff attended the focus groups. Time, knowledge of studies, difficulty in broaching the topic of research and patient factors were cited as barriers to recruitment. Suggestions to improve recruitment included: greater multi-disciplinary team involvement; improving staff research knowledge; streamlining the research process; and patient education. Reasons for different attitudes between staff disciplines towards research included different training pathways and incentives to conduct research. The recommendations staff have made to help drive recruitment should be implemented in the genito-urinary medicine clinic. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    The evolution of increased competitive ability (EICA) hypothesis predicts that invasive plant species may escape their specialized natural enemies in their introduced range and subsequently evolve with a decrease in investment in anti-herbivore chemical defenses relative to native conspecifics. We compared the chemical profile of 10 populations of US native and 20 populations of European invasive Solidago gigantea. To test for differences in inducibility between native and invasive populations, we measured secondary chemistry in both damaged and undamaged plants. We also performed bioassays with three specialist and two generalist insect herbivores from four different feeding guilds. There was no evidence that invasive populations had reduced concentrations of sesquiterpenes, diterpenes, or short-chain hydrocarbons (SCH), although significant variation among populations was detected. Sesquiterpene and diterpene concentrations were not influenced by damage to the host plant, whereas SCH concentrations were decreased by damage for both native and invasive plants. Performance of the three specialist insects was not affected by the continental origin of the host plant. However, larval mass of the generalist caterpillar Spodoptera exigua was 37% lower on native plants compared to invasive plants. The other generalist insect, a xylem-tapping spittlebug that occurs on both continents, performed equally well on native and invasive plants. These results offer partial support for the defense predictions of the EICA hypothesis: the better growth of Spodoptera caterpillars on European plants shows that some defenses have been lost in the introduced range, even though our measures of secondary chemistry did not detect differences between continents. Our results show significant variation in chemical defenses and herbivore performance across populations on both continents and emphasize the need for analysis across a broad spatial scale and the use of multiple herbivores.

    Opportunities for minorities in healthcare increased with the Civil Rights movement in the 1960s. More recently, funds from the U.S. Public Health Service have been targeted toward disadvantaged minorities. The workforce in healthcare, and in business in general, has become increasingly multicultural. Much of the literature in healthcare management lacks practical guidelines for managing a diverse workforce. Communication, both verbal and nonverbal, and culture are closely intertwined. Managers, as they develop multicultural teams, will need to understand how culture influences communication in their organizations. Space, spatial behavior, and cultural attitudes influence people's behavior. This is a particularly important consideration for a radiology staff, which must often work in close quarters. For some cultural groups, the family as an organization has more significance than even personal, work-related or national causes. People's orientation to time, whether for the past, present or future, is usually related to the culture in which they grew up. Again, this may become an important issue for a radiology administrator whose organization must run punctually and time-efficiently. How patients feel about their environment, whether they believe they are in control or believe in an external locus of control, is of particular interest to those who attempt therapeutic changes in a patient's healthcare. Does the patient believe that illness is divine will or that suffering is intrinsic to the human condition? There is increasing research in the United States to show that people do differ biologically according to race. Such differences exist among patients as well as among staff members. It has been popular to assume that differences among races do not exist. Unfortunately such an attitude does not allow for different attributes and responses of individuals. Managing a multicultural staff presents a challenge to administrators who must be skilled in working with

  18. A Game of Russian Roulette for a Generalist Dinoflagellate Parasitoid: Host Susceptibility Is the Key to Success.

    Marine microbial interactions involving eukaryotes and their parasites play an important role in shaping the structure of phytoplankton communities. These interactions may alter population densities of the main host, which in turn may have consequences for the other concurrent species. The effect generalist parasitoids exert on a community is strongly dependent on the degree of host specificity. Parvilucifera sinerae is a generalist parasitoid able to infect a wide range of dinoflagellates, including toxic-bloom-forming species. A density-dependent chemical cue has been identified as the trigger for the activation of the infective stage. Together these traits make Parvilucifera-dinoflagellate hosts a good model to investigate the degree of specificity of a generalist parasitoid, and the potential effects that it could have at the community level. Here, we present for the first time, the strategy by which a generalist dinoflagellate parasitoid seeks out its host and determine whether it exhibits host preferences, highlighting key factors in determining infection. Our results demonstrate that in its infective stage, P. sinerae is able to sense potential hosts, but does not actively select among them. Instead, the parasitoids contact the host at random, governed by the encounter probability rate and once encountered, the chance to penetrate inside the host cell and develop the infection strongly depends on the degree of host susceptibility. As such, their strategy for persistence is more of a game of Russian roulette, where the chance of survival is dependent on the susceptibility of the host. Our study identifies P. sinerae as a potential key player in community ecology, where in mixed dinoflagellate communities consisting of hosts that are highly susceptible to infection, parasitoid preferences may mediate coexistence between host species, reducing the dominance of the superior competitor. Alternatively, it may increase competition, leading to species exclusion. If

    Early colonization by Zyginidia scutellaris leafhoppers might be a key factor in the attraction and settling of generalist predators, such as Orius spp., in maize fields. In this paper, we aimed to determine whether our observations of early season increases in field populations of Orius spp. reflect a specific attraction to Z. scutellaris-induced maize volatiles, and how the responses of Orius predators to herbivore-induced volatiles (HIPVs) might be affected by previous experiences on plants infested by herbivorous prey. Therefore, we examined the innate and learned preferences of Orius majusculus toward volatiles from maize plants attacked by three potential herbivores with different feeding strategies: the leafhopper Z. scutellaris (mesophyll feeder), the lepidopteran Spodoptera littoralis (chewer), and another leafhopper Dalbulus maidis (phloem feeder). In addition, we examined the volatile profiles emitted by maize plants infested by the three herbivores. Our results show that predators exhibit a strong innate attraction to volatiles from maize plants infested with Z. scutellaris or S. littoralis. Previous predation experience in the presence of HIPVs influences the predator's odor preferences. The innate preference for plants with cell or tissue damage may be explained by these plants releasing far more volatiles than plants infested by the phloem-sucking D. maidis. However, a predation experience on D. maidis-infested plants increased the preference for D. maidis-induced maize volatiles. After O. majusculus experienced L3-L4 larvae (too large to serve as prey) on S. littoralis-infested plants, they showed reduced attraction toward these plants and an increased attraction toward D. maidis-infested plants. When offered young larvae of S. littoralis, which are more suitable prey, preference toward HIPVs was similar to that of naive individuals. The HIPVs from plants infested by herbivores with distinctly different feeding strategies showed distinguishable

    Full Text Available Since 2010 a survey has been conducted among first-year students about sources of information which influence the decision of undertaking field studies in Safety Engineering, Management Engineering and Logistics in the Faculty of Engineering Management at Poznan University of Technology. The goal of these analyses is both to assess the effectiveness of promotion and also show trends in the use of diverse channels of information transfer of studies. The results of the investigation show that internet promotion via university and faculty website plays the dominant role but also direct promotion, such as opinion of older friends, is crucial. Furthermore, from year to year the analyses indicate the significant increase of official media and reveal that the prospective students rely on a few sources of information simultaneously.

  18. Climate change alters the structure of arctic marine food webs due to poleward shifts of boreal generalists

    2015-01-01

    Climate-driven poleward shifts, leading to changes in species composition and relative abundances, have been recently documented in the Arctic. Among the fastest moving species are boreal generalist fish which are expected to affect arctic marine food web structure and ecosystem functioning substantially. Here, we address structural changes at the food web level induced by poleward shifts via topological network analysis of highly resolved boreal and arctic food webs of the Barents Sea. We detected considerable differences in structural properties and link configuration between the boreal and the arctic food webs, the latter being more modular and less connected. We found that a main characteristic of the boreal fish moving poleward into the arctic region of the Barents Sea is high generalism, a property that increases connectance and reduces modularity in the arctic marine food web. Our results reveal that habitats form natural boundaries for food web modules, and that generalists play an important functional role in coupling pelagic and benthic modules. We posit that these habitat couplers have the potential to promote the transfer of energy and matter between habitats, but also the spread of pertubations, thereby changing arctic marine food web structure considerably with implications for ecosystem dynamics and functioning.

  19. Widespread generalist clones are associated with range and niche expansion in allopolyploids of Pacific Northwest Hawthorns (Crataegus L.).

    Science.gov (United States)

    2017-10-01

    Range and niche expansion are commonly associated with transitions to asexuality, polyploidy and hybridity (allopolyploidy) in plants. The ability of asexual polyploids to colonize novel habitats may be due to widespread generalist clones, multiple ecologically specialized clones, or may be a neutral by-product of multiple, independent origins of asexual polyploids throughout the range. We have quantified niche size and divergence for hawthorns of the Pacific Northwest using data from herbarium vouchers with known cytotypes. We find that all polyploid niches diverge from that of the diploid range, and allopolyploids have the broadest niches. Allotetraploids have the largest niche and the widest geographic distribution. We then assessed the genetic mechanism of range expansion by surveying the ecological and geographic distribution of genotypes within each cytotype from sites in which fine-scale habitat assessments were completed. We find no isolation by either geographic or ecological distance in allopolyploids, suggesting high dispersal and colonization ability. In contrast, autotriploids and diploids show patterns of isolation by geographic distance. We also compared the geographic and ecological distributions of clonal genotypes with those of randomly drawn sites of the most widespread cytotype. We found that most clones are geographically widespread and occur in a variety of habitats. We interpret these findings to suggest that patterns of range and niche expansion in Pacific Northwest Hawthorns may stem from these widespread, ecologically generalist clones of hybrid origin. © 2017 John Wiley & Sons Ltd.

    Habitat specialist species are supposed to be more susceptible to variations in local environmental characteristics than generalists. To test this hypothesis, we conducted a comparative analysis on abundance and genetic diversity of forest carabids differing in their habitat requirements. Four species were sampled in forests characterized by abiotic, landscape and biotic environmental variables. A statistical framework based on canonical correspondence analysis was used for one habitat generalist and one habitat specialist species to determine the relative contribution of environmental variables in structuring inter- and intrapopulational genetic diversity depicted by microsatellites. Our results showed that sympatric species differed in their sensitivity to environmental variables. The same variables were found to be important in analyses of abundance and genetic data. However, specialization was not related to a greater sensitivity to local environmental characteristics. The strong impact of spatial variables on genetic data suggested that genetic variation among populations would largely reflect the response of individual species to dispersal opportunities more than the effect of habitat quality.

    Climate-driven poleward shifts, leading to changes in species composition and relative abundances, have been recently documented in the Arctic. Among the fastest moving species are boreal generalist fish which are expected to affect arctic marine food web structure and ecosystem functioning substantially. Here, we address structural changes at the food web level induced by poleward shifts via topological network analysis of highly resolved boreal and arctic food webs of the Barents Sea. We detected considerable differences in structural properties and link configuration between the boreal and the arctic food webs, the latter being more modular and less connected. We found that a main characteristic of the boreal fish moving poleward into the arctic region of the Barents Sea is high generalism, a property that increases connectance and reduces modularity in the arctic marine food web. Our results reveal that habitats form natural boundaries for food web modules, and that generalists play an important functional role in coupling pelagic and benthic modules. We posit that these habitat couplers have the potential to promote the transfer of energy and matter between habitats, but also the spread of pertubations, thereby changing arctic marine food web structure considerably with implications for ecosystem dynamics and functioning. © 2015 The Authors.

    The training of its staff is one of the pillars of the safe and economical operation of a power plant. This is why power plant owners began to systematically train their staff already in the 50s, and why they created central training facilities. Staff members who have undergone this training make an indispensable contribution to the acceptedly high safety and availability of German power plants. The substantial cost of creating training facilities and of schooling plant staff is considered to be an investment for the future. Low labour turnover permits careful observation and development of staff and leads to a high standard of knowledge and experience. (orig./HSCH) [de

    The aim of the study was to evaluate the effects of a six-month physical training undertaken by haemodialysis (HD) patients, on the depression and anxiety. Patients with end stage renal disease (ESRD) were recruited from the dialysis station at the Department of Nephrology and Transplantation Medicine in Wroclaw. Physical training took place at the beginning of the first 4-hours of dialysis, three times a week for six months. A personal questionnaire, Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI) were used in the study. A total of 28 patients completed the study: 20 were randomised to endurance training and 8 were randomised to resistance training. Statistical analysis of depression and anxiety at the initial (t1) and final examination (t2) indicated a significant reduction in depression and anxiety, particularly anxiety as a trait (X2) in the whole study group. The change in anxiety as a state correlated with the disease duration, duration of dialysis and the initial level of anxiety as a state (t1X1). The change in anxiety as a trait significantly correlated with age and the initial level of anxiety (t1X2). Undertaking physical training during dialysis by patients with ESRD is beneficial in reducing their levels of anxiety and depression. Both resistance and endurance training improves mood, but only endurance training additionally results in anxiety reduction. © 2016 S. Karger AG, Basel.

    Full Text Available The purpose of this study was to determine the effects of periodic task-specific test feedback on performance improvement in older adults undertaking community- and home-based resistance exercises (CHBRE. Fifty-two older adults (65–83 years were assigned to a muscular perfsormance feedback group (MPG, n=32 or a functional mobility feedback group (FMG, n=20. Both groups received exactly the same 9-week CHBRE program comprising one community-based and two home-based sessions per week. Muscle performance included arm curls and chair stands in 30 seconds, while functional mobility was determined by the timed up and go (TUG test. MPG received fortnightly test feedback only on muscle performance and FMG received feedback only on the TUG. Following training, there was a significant (P<0.05 interaction for all performance tests with MPG improving more for the arm curls (MPG 31.4%, FMG 15.9% and chair stands (MPG 33.7%, FMG 24.9% while FMG improved more for the TUG (MPG-3.5%, FMG-9.7%. Results from this nonrandomized study suggest that periodic test feedback during resistance training may enhance task-specific physical performance in older persons, thereby augmenting reserve capacity or potentially reducing the time required to recover functional abilities.

  12. Exploring the role of social interactions and supports in overcoming accessibility barriers while undertaking health tours in India.

    Jana, Arnab; Harata, Noboru; Kiyoshi, Takami; Ohmori, Nobuaki

    2014-01-01

    This article explores the phenomenon of companionship as an adaptation strategy to counter the existing barriers to health care access in developing nations. Companionship is argued to be an outcome of "inter" and "intra" household collaboration to offer diverse supports in addition to altruism. The analysis of the household survey conducted in West Bengal, India, exhibited different patterns of health care tours and the associated dependencies. In addition to support in terms of mobility while traveling and companionship while waiting for the opportunity, support in terms of refuge is also found to be essential, especially for the poor while they undertake regional tours. Causal models focusing on aggregated general health tours and specific regional tours were estimated separately to comprehend the implicit social interactions and their effects on the patient as well as the companions. The research demonstrated that accessibility barriers affect not only the ill, but also those associated with them and at times adversely. Segregation of regional tours illustrated the gaps, which instigated such tours and also might aid in health infrastructure planning as a whole.

    This paper reports on an evaluation of a Teaching and Learning Enhancement Scheme (TALES) program designed to meet the unique need of the 2005 cohort of international nursing students undertaking an accelerated Bachelor of Nursing (BN) program at the Victorian campus of Australian Catholic University (ACU) National. The program involved a team approach with three academic mentors and the international students working together to produce satisfactory learning outcomes through fortnightly meetings and provision of additional assistance including compiling a portfolio, reflective writing, English, including colloquial English and pronunciation, as well as familiarisation with handover and abbreviations common in the clinical field, general communication, assistance with preparing a resume and participation in simulated interviews. This relatively small group of international students (20) confirmed the findings of other studies from other countries of international nursing students' in terms of concerns in regard to studying in a foreign country, namely English proficiency, communication difficulties, cultural differences and unfamiliarity with the health care environment. The assistance provided by the program was identified by the completing students as invaluable in helping them settle into study and successfully complete the theoretical and clinical components of the course.

    This article discusses the preparation, structure and objectives of the Bio-based Industries Joint Undertaking (BBI JU). BBI JU is a public-private partnership (PPP) between the European Commission (EC) and the Bio-based Industries Consortium (BIC), the industry-led private not-for-profit organisation representing the private sectors across the bio-based industries. The model of the public-private partnership has been successful as a new approach to supporting research and innovation and de-risking investment in Europe. The BBI JU became a reality in 2014 and represents the largest industrial and economic cooperation endeavour financially ever undertaken in Europe in the area of industrial biotechnologies. It is considered to be one of the most forward-looking initiatives under Horizon 2020 and demonstrates the circular economy in action. The BBI JU will be the catalyst for this strategy to mobilise actors across Europe including large industry, small and medium-sized enterprises (SMEs), all types of research organisations, networks and universities. It will support regions and in doing so, the European Union Member States and associated countries in the implementation of their bioeconomy strategies. Copyright © 2017 Elsevier B.V.

    Full Text Available The object of the paper is to analyze the spatial structure of land and identification of the needs of consolidation works and exchange of land in the villages of the Sławno municipality, lying in the district of Opoczno, in the Łódzkie Voivodship. The authors use the method of zero unitarisation for the purposes of determining the order of undertaking consolidation works and exchange of land in the area of research. The basis for calculation is the database of 19 factors (x1–x19 characteristic for the listed five groups of issues, describing each of the following villages. The obtained results, in a form of synthetic meter for each village, allowed creating the hierarchy of the urgency of carrying out consolidation works. The problem of excessive fragmentation of farms, constituting the collections of a certain number of parcels, in a broader sense, is one of the elements that prevent the acceleration of reforms by conversion of the Land and Buildings Register (EGiB in a full valuable real estate cadastre in Poland. The importance of the problem is highlighted by the fact that there are ecological grounds in the study area, significant from the point of view of environmental protection.

  16. Chinese Anti-Cancer Association as a non-governmental organization undertakes systematic cancer prevention work in China

    Science.gov (United States)

    2015-01-01

    Cancer has become the first leading cause of death in the world, particularly in low- and middle-income countries. Facing the increasing trend of cancer incidence and mortality, China issued and implemented “three-early (early prevention, early diagnosis and early treatment)” national cancer prevention plan. As the main body and dependence of social governance, non-governmental organizations (NGOs) take over the role of government in the field of cancer prevention and treatment. American Cancer Society (ACS) made a research on cancer NGOs and civil society in cancer control and found that cancer NGOs in developing countries mobilize civil society to work together and advocate governments in their countries to develop policies to address the growing cancer burden. Union for International Cancer Control (UICC), Cancer Council Australia (CCA), and Malaysian cancer NGOs are the representatives of cancer NGOs in promoting cancer control. Selecting Chinese Anti-Cancer Association (CACA) as an example in China, this article is to investigate how NGOs undertake systematic cancer prevention work in China. By conducting real case study, we found that, as a NGO, CACA plays a significant role in intensifying the leading role of government in cancer control, optimizing cancer outcomes, decreasing cancer incidence and mortality rates and improving public health.

In general the duties of the operational staff involve tasks such as secretarial assistance, keeping log of the progress of the situation and gathering, updating and distributing information on all aspects of the situation. Throughout the entire event it is the staff`s responsibility to keep a general view of the current situation and to make the necessary plans for the progress of the situation based on the available information. Furthermore the staff should ensure necessary contact to the public and to the media. (au).

  2. Community-level patterns of population recruitment in a generalist avian brood parasite, the brown-headed cowbird.

    2010-07-01

    The brown-headed cowbird (Molothrus ater) is a generalist brood parasite that typically parasitizes many host species in a single bird community. Population recruitment in a generalist parasite should be diverse with respect to host species; however, host-specific rates of cowbird recruitment have not been reported in any host community, and the determinants of host quality are poorly known. We studied the combined influence of parasitism level, nest abundance, and host quality on community-level patterns of cowbird recruitment in New Mexico, USA. Our objectives were to: (1) evaluate patterns of host use and quality; (2) compare cowbird egg investment and recruitment among host species; (3) identify host species of most importance to cowbird recruitment. Cowbirds parasitized 11 host species, with five "major" hosts experiencing high parasitism levels (>or=1 cowbird egg/nest) and six minor hosts experiencing low parasitism levels (Parasitism level was not correlated with host species abundance, host mass, host nestling period length, or host success at fledging cowbirds. However, tree-nesting hosts were parasitized more than ground-nesters, and foliage-gleaners more than sally-foragers and ground-foragers. Average estimated survival to fledging of cowbird eggs laid in active host nests was 0.19. Cowbird recruitment was diverse with respect to hosts but was less evenly distributed across the host community than was cowbird egg investment because western tanagers (Piranga ludovicianus) fledged cowbirds more successfully than other hosts. This success in western tanagers was due to high cowbird survivorship in tanager nests and may be associated with the larger body size of tanagers relative to other hosts.

  8. A systematic scoping review of the evidence for consumer involvement in organisations undertaking systematic reviews: focus on Cochrane.

    Science.gov (United States)

    Morley, Richard F; Norman, Gill; Golder, Su; Griffith, Polly

    2016-01-01

    Cochrane is the largest international producer of systematic reviews of clinical trial evidence. We looked for published evidence that reports where consumers (patients and the public) have been involved in Cochrane systematic reviews, and also in reviews published by other organisations.We found 36 studies that reported about consumer involvement either in individual systematic reviews, or in other organisations. The studies showed that consumers were involved in reviews in a range of different ways: coordinating and producing reviews, making reviews more accessible, and spreading the results of reviews ("knowledge transfer"). The most common role was commenting on reviews ("peer reviewing"). Consumers also had other general roles, for example in educating people about evidence or helping other consumers. There were some interesting examples of new ways of involving consumers. The studies showed that most consumers came from rich and English speaking countries. There was little evidence about how consumer involvement had changed the reviews ("impact"). The studies found that consumer involvement needed to be properly supported.In future we believe that more research should be done to understand what kind of consumer involvement has the best impact; that more review authors should report how consumers have been involved; and that consumers who help with reviews should come from more varied backgrounds. Background Cochrane is the largest international producer of systematic reviews, and is committed to consumer involvement in the production and dissemination of its reviews. The review aims to systematically scope the evidence base for consumer involvement in organisations which commission, undertake or support systematic reviews; with an emphasis on Cochrane. Methods In June 2015 we searched six databases and other sources for studies of consumer involvement in organisations which commission, undertake or support systematic reviews, or in individual systematic

    Functional hypothalamic amenorrhea (FHA) refers to a functional menstrual disorder with various causes and presentations. Recovery of menstrual cyclicity is common in long-term follow-up but the affecting factors remain unknown. To explore factors affecting the menstrual resumption and to evaluate the pituitary response to gonadotropin-releasing hormone (GnRH) in FHA. Thirty cases with FHA were recruited. All subjects were put on continuous 1 mg/day estradiol valerate orally and followed up monthly. Recovery was defined as the occurrence of at least three consecutive regular cycles. Responder referred to those who recovered within two years of therapy. Gonadotropin response to the 50 μg GnRH challenge was tested every three months. Nineteen (63.3%) subjects recovered with a mean time to recovery of 26.8 months. Time to recovery was negatively correlated with body mass index (BMI) before and by amenorrhea. Twentyone cases had undertaken therapy for more than two years and 10 of them recovered. BMI before and by amenorrhea were negatively correlated with the recovery. Significant increase of serum luteinizing hormone (LH) and LH response to GnRH were noted after recovery. Menstrual resumption was common in FHA undertaking estrogen replacement therapy (ERT). The likelihood of recovery was affected by their BMI before and by amenorrhea but not by the weight gain during therapy. Low serum LH and attenuated LH response to GnRH were the main features of pituitary deficiency in FHA. The menstrual resumption in FHA was accompanied by the recovery of serum LH and the LH response to GnRH.

    Developing research capacity is recognised as an important endeavour. However, little is known about the current research culture, capacity and supports for staff working in community-based health settings. A structured survey of Division of Community Health staff was conducted using the research capacity tool. The survey was disseminated by email and in paper format. Quantitative data were analysed using descriptive statistics. Qualitative data were analysed thematically. In total, 109 usable responses were received, giving a response rate of 26%. Respondents were predominately nurses (n=71, 65.7%), with ~50% reporting post-graduate vocational qualifications. The highest levels of skills or organisational success were in using evidence to plan, promote and guide clinical practice. Most participants were unsure of organisational and team level skills and success at generating research. Few reported recent experience in research-generating activities. Barriers to undertaking research included lack of skills, time and access to external support and funding. Lack of skills and success in accessing external funding and resources to protect research time or to 'buy-in' technical expertise appeared to exacerbate these barriers. Community health staff have limited capacity to generate research with current levels of skill, funding and time. Strategies to increase research capacity should be informed by knowledge of clinicians' research experience and interests, and target development of skills to generate research. Resources and funding are needed at the organisational and team levels to overcome the significant barriers to research generation reported.

    Turner, Mary; Payne, Sheila; O'Brien, Terri

    2011-12-01

    There is increasing recognition of the importance of good communication between healthcare professionals and patients facing cancer or end of life. In England, a new national 3-day training programme called 'Connected' has been developed and is now mandatory for all cancer and palliative care professionals. This study aimed to explore the attitudes of staff in one region to undertaking this training. A survey questionnaire was developed through a series of discussions with experts and semi-structured interviews with five healthcare professionals. The questionnaire was distributed to 200 cancer and palliative care staff; 109 were completed and returned. There were significant differences between doctors' and nurses' attitudes to communication skills training, with doctors demonstrating more negative attitudes. More nurses than doctors felt that communication skills training should be mandatory for cancer and palliative care professionals (p ≤ 0.001), whilst more doctors felt that these staff should already be skilled communicators and not require further training (p ≤ 0.001). Nurses also self-rated their communication skills more highly than doctors. The current 'one size fits all' approach being taken nationally to advanced communication skills training does not meet the training preferences of all healthcare professionals, and it is recommended that tailoring courses to individuals' needs should be considered.

    With more than 100 participants entering the exercise RESUME-95 the Exercise Planning Committee decided to establish an operational staff named Directing Staff (DISTAFF) to ensure that the exercise plan was followed, the planned activities were carried out and to intervene if anything went wrong. In general the duties of the operational staff involve tasks such as secretarial assistance, keeping log of the progress of the situation and gathering, updating and distributing information on all aspects of the situation. Throughout the entire event it is the staff's responsibility to keep a general view of the current situation and to make the necessary plans for the progress of the situation based on the available information. Furthermore the staff should ensure necessary contact to the public and to the media. (au)

    2006-01-01

    To determine the prevalence of burnout syndrome components among the medical and nursing staff of the second care level hospitals of the Instituto Mexicano del Seguro Social and Instituto de Seguridad Social al Servicio de los Trabajadores del Estado from Durango, Mexico. A cross-sectional comparative study was carried out among 73 physicians and 100 nurses randomly selected from both hospitals. The prevalence of burnout syndrome components was established by the Maslash Burnout Inventory, which determines the presence of physical/emotional exhaustion, depersonalization, and labor performance. In addition, sociodemographic and labor information was collected. Prevalence was calculated with a reliability interval of 95% (CI 95%). 73 physicians and 100 nurses enrolled, corresponding to 22.8% and 14.5% of such personnel working in both institutions. Among the IMSS and ISSSTE workers respectively, the prevalence of depersonalization was 43.2% (34.4-52.9) and 14.5% (6.8-25.8), whereas the prevalence of physical/emotional exhaustion was 41.4% (32.7-51.1) and 19.4% (10.4-31.4). Pre-valence of labor performance was higher among the personnel of Instituto Mexicano del Seguro Social: 99.1% (95.1-100) versus 96.8% (88.8-100). Severe depersonalization (p = 0.004), but not emotional exhaustion (p = 0.09) nor labor performance (p = 0.06) was significantly higher among personnel working at the Instituto Mexicano del Seguro Social. Prevalence of depersonalization and physical/emotional exhaustion was higher among physicians and nurses of the Instituto Mexicano del Seguro Social; nonetheless, their labor performance was high. Our finding suggests that personnel working at the Instituto Mexicano del Seguro Social make a greater effort to maintain the high labor performance that medical care requires.

    Haug, Nancy A; Kieschnick, Dustin; Sottile, James E; Babson, Kimberly A; Vandrey, Ryan; Bonn-Miller, Marcel O

    2016-01-01

    Introduction: The proliferation of cannabis dispensaries within the United States has emerged from patient demand for the legalization of cannabis as an alternative treatment for a number of conditions and symptoms. Unfortunately, nothing is known about the practices of dispensary staff with respect to recommendation of cannabis strains/concentrations for specific patient ailments. To address this limitation, the present study assessed the training and practices of cannabis dispensary staff. Materials and Methods: Medical and nonmedical dispensary staff ( n =55) were recruited via e-mail and social media to complete an online survey assessing their demographic characteristics, dispensary features, patient characteristics, formal training, and cannabis recommendation practices. Results: Fifty-five percent of dispensary staff reported some formal training for their position, with 20% reporting medical/scientific training. A majority (94%) indicated that they provide specific cannabis advice to patients. In terms of strains, dispensary staff trended toward recommendations of Indica for anxiety, chronic pain, insomnia, nightmares, and Tourette's syndrome. They were more likely to recommend Indica and hybrid plants for post-traumatic stress disorder (PTSD)/trauma and muscle spasms. In contrast, staff were less likely to recommend Indica for depression; hybrid strains were most often recommended for amyotrophic lateral sclerosis (ALS). In terms of cannabinoid concentrations, dispensary staff were most likely to recommend a 1:1 ratio of delta-9-tetrahydrocannabinol (THC):cannabidiol (CBD) for patients suffering from anxiety, Crohn's disease, hepatitis C, and PTSD/trauma, while patients seeking appetite stimulation were most likely to be recommended THC. Staff recommended high CBD for arthritis and Alzheimer's disease and a high CBD or 1:1 ratio for ALS, epilepsy, and muscle spasms. Conclusions: Although many dispensary staff are making recommendations consistent with

    Full Text Available The Statutory Instrument of September 2007 approved as part of the regulatory powers of the Education Act (DfES, 2002 established regulations for a minimum undertaking of 30 hours’ Continuing Professional Development (CPD for all teaching staff on a year-on-year basis. Seen as part of the professionalisation agenda for the Further Education (FE sector, this regulation has placed additional responsibilities on the role of Middle Managers. Here we report on a small-scale research project based in one College of Further Education which set out to explore and better understand the role of Middle Managers in supporting the professionalisation agenda. The study determined to explore how Middle Managers, defined as those with operational rather than strategic roles, were supporting their colleagues whilst also trying to secure time for their own Continuing Professional Development (CPD. The impact of the IfL’s approach to dual professionalism is also explored.

    Toline, B.C.

    1991-01-01

    In September of 1989 Cooper Nuclear Station began a project to upgrade the Technical Staff Training Program. This project's roots began by performing job and Task Analysis for Technical Staff. While the industry has long been committed to Job and Task Analysis to target performance based instruction for single job positions, this approach was unique in that it was not originally considered appropriate for a group as diverse as Tech Staff. Much to his satisfaction the Job and Task Analysis Project was much less complicated for Technical Staff than the author had imagined. The benefits of performing the Job and Task Analysis for Technical Staff have become increasingly obvious as he pursues lesson plan development and course revisions. The outline for this presentation will be as follows: philosophy adopted; preparation of the job survey document; performing the job analysis; performing task analysis for technical staff and associated pitfalls; clustering objectives for training and comparison to existing program; benefits now and in the future; final phase (comparison to INPO guides and meeting the needs of non-degreed engineering professionals); and conclusion. By focusing on performance based needs for engineers rather than traditional academics for training the author is confident the future Technical Staff Program will meet the challenges ahead and will exceed requirements for accreditation

    The purpose of this paper is to provide education on blood-borne viruses (BBVs) to prison staff to help reduce stigma within the prisons, improve the care prisoners receive and reduce the risk of occupational transmission. An e-module was used to improve staff understanding of hepatitis B (HBV), hepatitis C (HCV) and HIV at a prison in Wales, UK. An assessment was used to gather data on prison staff understanding of BBVs prior to undertaking the e-module. In total, 530/697 (76 per cent) prison staff completed the BBV e-module. Average pre- and post-course assessment scores were 8.6/11 and 10.85/11, respectively. Most staff understood the modes of hepatitis transmission, however, gaps in understanding were highlighted. In total, 22 per cent of staff believed HBV and HCV were airborne, 9 per cent believed transmission occurred through sharing cutlery. In total, 31 per cent of staff believed prisoners with hepatitis should declare their status to the prison. Practical implications: The e-module significantly improved staff understanding of BBVs and should be incorporated into future prison training packages. Future education should include how BBVs are not transmitted with an emphasis on casual contact. Medical confidentiality in prisons should also be addressed. Improving understanding will help reduce the stigma of BBVs within prison and improve the multidisciplinary care the prisoner receives. To the authors knowledge this is the first published evaluation of a BBV learning package for custodial staff. Evaluation of this educational package demonstrates a unique and valuable insight into the general understanding of BBVs by prison staff in Wales, UK.

  15. Cooptation of Peer Support Staff: Quantitative Evidence

    2014-03-01

    Full Text Available Objective In 2007, the Centers for Medicare and Medicaid Services (CMS sent a letter to state Medicaid directors outlining requirements for implementing peer-based recovery support services (P-BRSS as a Medicaid-funded service. Since then, 30 states have implemented these services. Although the literature describing implementation of P-BRSS has identified the cooptation of peer support staff (PSS as a barrier to the effective provision of P-BRSS, the evidence for it remains anecdotal. This study attempts to determine if the context of employment in either a treatment organization or peer organization affected cooptation. Methods We conducted a survey of PSS in the fall of 2013. In all, 92 of the 181 respondents were working as PSS at the time, 53 in treatment organizations. Chi-square analysis was used to determine if the context of employment had an effect on the cooptation of peer staff. Results Peer staff working in treatment organizations reported that they were supervised by treatment staff and participated in employment-related training to improve their skills at providing treatment services more frequently than their counterparts in peer organizations. Peer staff working in treatment organizations also participated in training and education to prepare for employment as treatment professionals more frequently than peer staff working in peer organizations. Conclusions and Implications for Practice Peer staff members working in treatment organizations are subject to processes of acculturation into professional cultures that peer staff working in peer organizations are not. Effective implementation of P-BRSS should include specific efforts to minimize the cooptation of peer staff.

  16. STAFF MARKETING IN MODERN RUSSIAN CONDITIONS

    2017-09-01

    Full Text Available The conception of staff marketing, which was developed abroad, is effectively used in the developed countries for a long time. Its main advantage consists in the possibility of organizing some planning for the implementation of staff strategy: staff marketing provides the enterprise on the long-term basis with human resources capable of forming strategic potential, which would allow to implement the planned activities. Numerous problems of formation and development of civilized market relations in our country do not allow to fully implement the detailed models of staff marketing in domestic realities. On the basis of the analysis of theoretical developments and factors that have a practical impact on the implementation of marketing personnel in modern Russian conditions, the authors describe the essential elements of the conception. The primary purposes of staff marketing for domestic enterprises, grouped into the internal and external marketing are substantiated and disclosed. The special attention is paid to increasing the staff loyalty, which has dominant influence on business outcomes. The algorithm of events for the development of motivation system is proposed; at the stage of studying job satisfaction it is recommend to apply analytical calculations with the use of Shewhart control charts. Unlike traditional statistical tools based on the inspection of already implemented results, this approach is aimed at preventing negative tendencies and avoids losses associated with dissatisfaction with difficulty, as the individual employee and the team as a whole. Modern Russian enterprises can fully realize the conception of staff marketing only through rethinking of the consequences for all directions of work with the staff, as reflected in the definition of objectives, motivating staff and ensuring social responsibility of the enterprise.

  17. Guidance for nuclear medicine staff on radiopharmaceuticals drug interaction

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available Numerous drug interactions related to radiopharmaceuticals take place every day in hospitals many of which are not reported or detected. Information concerning this kind of reaction is not abundant, and nuclear medicine staff are usually overwhelmed by this information. To better understand this type of reaction, and to help nuclear medicine staff deal with it, a review of the literature was conducted. The results show that almost all of radiopharmaceuticals marketed around the world present drug interactions with a large variety of compounds. This suggests that a logical framework to make decisions based on reviews incorporating adverse reactions must be created. The review also showed that researchers undertaking a review of literature, or even a systematic review that incorporates drug interactions, must understand the rationale for the suggested methods and be able to implement them in their review. Additionally, a global effort should be made to report as many cases of drug interaction with radiopharmaceuticals as possible. With this, a complete picture of drug interactions with radiopharmaceuticals can be drawn.Diversos casos de interações medicamentosas com radiofármacos ocorrem diariamente na rotina hospitalar, contudo muitos deles não são notificados ou mesmo percebidos. Informações a respeito desse tipo de reação não é abundante e os profissionais da medicina nuclear muitas vezes estão assoberbados por essas informações. De modo a entender esse tipo de reação e auxiliar a medicina nuclear a lidar com essa situação uma revisão da literatura foi realizada. Os resultados mostraram que a totalidade dos radiofármacos comercializados no mundo apresentam interação medicamentosa com uma enorme variedade de outros medicamentos. Dessa forma sugere-se que revisões sobre radiofármacos inclua um capítulo sobre efeitos adversos. Além disso, um esforço mundial para notificar efeitos adversos deve ser realizado, pois somente

  18. Undertaking a Collaborative Rapid Realist Review to Investigate What Works in the Successful Implementation of a Frail Older Person's Pathway.

    LENUS (Irish Health Repository)

    2018-01-25

    We addressed the research question "what factors enable the successful development and implementation of a frail older person\\'s pathway within the acute setting". A rapid realist review (RRR) was conducted by adopting the RAMESES standards. We began with a sample of 232 articles via database searches supplemented with 94 additional records including inputs from a twitter chat and a hospital site visit. Our final sample consisted of 18 documents. Following review and consensus by an expert panel we identified a conceptual model of context-mechanism-(resources)-outcomes. There was overall agreement frailty should be identified at the front door of the acute hospital. Significant challenges identified related to organisational boundaries both within the acute setting and externally, the need to shift outcomes to patient orientated ones, to support staff to sustain the pathway by providing ongoing education and by providing role clarity. RRRs can support research such as the systematic approach to improving care for frail older adults (SAFE) study by producing accounts of what works based on a wide range of sources and innovative engagement with stakeholders. It is evident from our provisional model that numerous factors need to combine and interact to enable and sustain a successful frail older person\\'s pathway.

  19. Cancer patients undertaking bone scans in a department of Nuclear Medicine have significant stress related to the examination

    Sioka, C.; Manetou, M.; Dimakopoulos, N.; Christidi, S.; Kouraklis, G.

    2005-01-01

    Bone scanning is a standard screening procedure for evaluation of metastases in cancer patient. In addition to the staging procedures, bone scan is a valuable test for deciding palliative therapeutic options in selected patients. The aim of this study was to investigate if patients with cancer who were undertaking routine bone scans had any stress related to the test. We asked 83 consecutive patients with various types of cancer if they had anxiety just prior to undergoing the test. Overall, we found that 53 (64%) patients had increased anxiety related to the examination and 30 (36%) patients did not. Among the 53 patients who were anxious about the bone scan, 32 were concerned about the results of the examination, 13 worried about the effects of the radiation, 4 were anxious for both results/radiation, and 4 patients had stress but could not specify the reason. Among the 32 patients who were concerned about the results of the examination, 15 were having their first bone scans, while 17 had already undergone the procedure before. Among the 13 patients who were mainly concerned about the risks of the radiation exposure during the test, 9 were having bone scans for the first time. Out of the 4 patients who feared both the results and radiation, 3 were having bone scans for the first time and 1 had it for several times. Finally, out of the 4 patients who had anxiety about the test but could not identify the reason, 3 were having bone scans for the first time and one had the test before but was claustrophobic. Our findings indicate that most patients (64%) with cancer who underwent a routine bone scan to check for metastatic disease had intense stress related either to the results or the side effects of the examination. However, there were more patients who were concerned about the results of the test rather than the effects of radiation. Among the patients who feared the effects of radioactivity most were having the test for the first time. A previous study in a

  2. Responses of Arabidopsis thaliana plant lines differing in hydroxylation of aliphatic glucosinolate side chains to feeding of a generalist and specialist caterpillar.

    Science.gov (United States)

    Rohr, F; Ulrichs, C; Schreiner, M; Zrenner, R; Mewis, I

    2012-06-01

    Plants contain variable chemical compositions which play a role in direct defense against phytophagous insects. Glucosinolates (GSs) are the predominant secondary metabolites and defense compounds in brassicaceous species. As a consequence of co-evolution between adapted crucifer-feeding specialists and their associated host-plants, specific plant-insect interactions have developed in a divergent manner from non-adapted generalists. Therefore, generalist and specialist insects may provoke different insect-inducible plant responses. Here, we have investigated the specific biochemical and molecular plant responses of Arabidopsis thaliana (L.) induced by the generalist Spodoptera exigua (Hübner) and the specialist Pieris brassicae L. To get more detailed information about herbivore-mediated-specific plant responses in different chemotypes within one species, we used multiple plant lines with either the non-hydroxylated 3-methylsulfinylpropyl GS or the hydroxylated 3-hydroxypropyl GS in a comparable genetic background. Caterpillar feeding induced a stronger GS accumulation in the 3-hydroxypropyl GS chemotype than the 3-methylsulfinylpropyl GS chemotype, considering the overall insect-mediated changes in aliphatic and indole GS levels in all lines. Herbivory by the generalist S. exigua and the specialist P. brassicae had similar effects on biochemical and transcriptional response pattern. Contrary to the paradigm that specialists may minimize the induction of chemical defenses, we observed a higher elicitation of GSs by the specialist species. The accumulation of especially 1-methoxy-indol-3-ylmethyl GS and the induced gene transcripts by the two species point to an insect-mediated activation of the jasmonic acid signaling pathway in the plant lines.

    2010-12-01

    Peter MacCallum Cancer Centre has one of the world's most enduring staff Christmas choirs. Commencing in 1956, the choir performs in a cafeteria, patient wards, and outpatient waiting areas before each Christmas. With recent emphasis on oncology staff support needs the choir's relevance warranted investigation. This constructivist research examined what effect the staff Christmas choir had on the choir members and staff bystanders in 2008. Sampling was convenience and purposive. Staff choir members were invited to participate during rehearsals, and staff bystanders were invited at seven choir performances in the hospital. Respondents completed anonymous and semistructured questionnaires and the conductor (of 29 years) was interviewed. The inductive, comparative, and cyclic data analyses were informed by grounded theory and qualitative interrater reliability was performed. Questionnaires from 64 staff were returned. The choir elicited positive emotions, memories, Christmas spirit, hospital community and/or work-life effects for many staff, in a cancer context described as sometimes "overwhelming" and "stressful." Choir members' reactions included stress relief, friendship and feeling rewarded. Bystanders' reactions included feeling uplifted, inspired and moved. Suggestions for future performances were offered, including musical acknowledgement of other religious festivals. Two respondents were concerned about intrusive effects on patients and work practices. A staff Christmas choir supported most choir member and staff bystander respondents in an oncology hospital and is recommended in comparable contexts. Further investigation is warranted to extend understanding about Christmas music's effects in palliative care settings.

    Staff members working on our nonmental health (non-MH) units (i.e., medical-surgical [MS] units) were not educated in recognizing or deescalating behavioral emergencies. Published evidence suggests a behavioral emergency response team (BERT) composed of MH experts who assist with deescalating behavioral emergencies may be beneficial in these situations. Therefore, we sought to implement a BERT on the inpatient non-MH units at our military treatment facility. The objectives of this evidence-based practice process improvement project were to determine how implementation of a BERT affects staff and patient safety and to examine nursing staffs' level of knowledge, confidence, and support in caring for psychiatric patients and patients exhibiting behavioral emergencies. A BERT was piloted on one MS unit for 5 months and expanded to two additional units for 3 months. Pre- and postimplementation staff surveys were conducted, and the number of staff assaults and injuries, restraint usage, and security intervention were compared. The BERT responded to 17 behavioral emergencies. The number of assaults decreased from 10 (pre) to 1 (post); security intervention decreased from 14 to 1; and restraint use decreased from 8 to 1. MS staffs' level of BERT knowledge and rating of support between MH staff and their staff significantly increased. Both MS and MH nurses rated the BERT as supportive and effective. A BERT can assist with deescalating behavioral emergencies, and improve staff collaboration and patient and staff safety. © 2017 Sigma Theta Tau International.

    Full Text Available Abstract Background Mesophotic corals (light-dependent corals in the deepest half of the photic zone at depths of 30 - 150 m provide a unique opportunity to study the limits of the interactions between corals and endosymbiotic dinoflagellates in the genus Symbiodinium. We sampled Leptoseris spp. in Hawaii via manned submersibles across a depth range of 67 - 100 m. Both the host and Symbiodinium communities were genotyped, using a non-coding region of the mitochondrial ND5 intron (NAD5 and the nuclear ribosomal internal transcribed spacer region 2 (ITS2, respectively. Results Coral colonies harbored endosymbiotic communities dominated by previously identified shallow water Symbiodinium ITS2 types (C1_ AF333515, C1c_ AY239364, C27_ AY239379, and C1b_ AY239363 and exhibited genetic variability at mitochondrial NAD5. Conclusion This is one of the first studies to examine genetic diversity in corals and their endosymbiotic dinoflagellates sampled at the limits of the depth and light gradients for hermatypic corals. The results reveal that these corals associate with generalist endosymbiont types commonly found in shallow water corals and implies that the composition of the Symbiodinium community (based on ITS2 alone is not responsible for the dominance and broad depth distribution of Leptoseris spp. The level of genetic diversity detected in the coral NAD5 suggests that there is undescribed taxonomic diversity in the genus Leptoseris from Hawaii.

    This paper provides a useful tool for the undergraduate community/public health nursing (C/PHN) faculty member to design courses and learning activities, and to interpret C/PHN education needs to undergraduate curriculum committees and administrators. Specifically, this paper provides a tangible bridge between the Public Health Nursing Competencies (Quad Council of Public Health Nursing Organizations, 2004) and the Association of Community Health Nursing Educators (ACHNE) Essentials of Baccalaureate Education (2000) for both didactic and clinical learning experiences. The tables may be used in multiple ways, including curriculum monitoring and improvement, course development and instructional design, clinical practice planning, and as a foundation for evaluation of conceptual learning and practice competence for the C/PHN generalist. Because C/PHN experiences in undergraduate education are unique and context based, the tables exemplify how two key guiding documents mutually frame the C/PHN educational experience supported by specific learning activities. Further, at a minimum, MSN preparation as a C/PHN specialist is clearly necessary for the teaching and learning of baccalaureate curricular components of C/PHN.

    Species richness and seasonal abundance of solitary bees were investigated in rocky, montane grassland (campo rupestre) (1180 m asl) and cerrado sensu stricto (680 m asl) in the Biribiri State Park, Diamantina, state of Minas Gerais, Brazil. Three hundred nineteen nest traps of bamboo canes and black cardboard tubes were monthly inspected at each site during 15 months. A total of eight species of bees built 97 nests. Four species were common to both sites. Tetrapedia aff. curvitarsis Friese and Tetrapedia aff. peckoltii Friese were the most abundant at campo rupestre and cerrado s.s., respectively, followed by Centris analis (Fabricius) in campo rupestre and Centris tarsata Smith in cerrado s.s. The nesting peaks occurred in May in campo rupestre and in February in cerrado s.s. Three cuckoo bees and one bee-fly were collected as natural enemies. The findings suggest that differences between the sites were related more to ecological factors (floral resources, natural nest sites) than to the altitudinal difference. The species richness was similar to that in other habitats with open vegetation. We demonstrate the need to use several types of trap-nest to increase the range of species sampled; some species used only one of the two types traps provided. We also comment on the limitations of trap-nests in cerrado vegetation. Most cerrado species of bees are very selective in their choice for a nesting site, but bees that use trap-nests are more generalists.

    Generalist insect can utilize two different modes for regulating their detoxification genes, the constitutive mode and the induced mode. Here, we used the Bemisia tabaci sibling species MEAM1 and MED, as a model system for studying constitutive and induced detoxification resistance and their associated tradeoffs. B. tabaci adults were allowed to feed through membranes for 24 h on diet containing only sucrose or sucrose with various phytotoxins. Quantitative real-time PCR analyses of 18 detoxification genes, indicated that relatively few transcripts were changed in both the MEAM1 and MED species, in response to the addition of phytotoxins to the diet. Induced transcription of detoxification genes only in the MED species, in response to the presence of indole-3-carbinol in the insect's diet, was correlated with maintenance of reproductive performance in comparison to significant reduction in performance of the MEAM1 species. Three genes, COE2, CYP6-like 5 and BtGST2, responded to more than one compound and were highly transcribed in the insect gut. Furthermore, functional assays showed that the BtGST2 gene encodes a protein capable of interacting with both flavonoids and glucosinolates. In conclusion, several detoxification genes were identified that could potentially be involved in the adaptation of B. tabaci to its host plants.

  11. Low susceptibility of invasive red lionfish (Pterois volitans to a generalist ectoparasite in both its introduced and native ranges.

    Directory of Open Access Journals (Sweden)

    Paul C Sikkel

    Full Text Available Escape from parasites in their native range is one of many mechanisms that can contribute to the success of an invasive species. Gnathiid isopods are blood-feeding ectoparasites that infest a wide range of fish hosts, mostly in coral reef habitats. They are ecologically similar to terrestrial ticks, with the ability to transmit blood-borne parasites and cause damage or even death to heavily infected hosts. Therefore, being highly resistant or highly susceptible to gnathiids can have significant fitness consequences for reef-associated fishes. Indo-Pacific red lionfish (Pterois volitans have invaded coastal habitats of the western tropical and subtropical Atlantic and Caribbean regions. We assessed the susceptibility of red lionfish to parasitic gnathiid isopods in both their native Pacific and introduced Atlantic ranges via experimental field studies during which lionfish and other, ecologically-similar reef fishes were caged and exposed to gnathiid infestation on shallow coral reefs. Lionfish in both ranges had very few gnathiids when compared with other species, suggesting that lionfish are not highly susceptible to infestation by generalist ectoparasitic gnathiids. While this pattern implies that release from gnathiid infestation is unlikely to contribute to the success of lionfish as invaders, it does suggest that in environments with high gnathiid densities, lionfish may have an advantage over species that are more susceptible to gnathiids. Also, because lionfish are not completely resistant to gnathiids, our results suggest that lionfish could possibly have transported blood parasites between their native Pacific and invaded Atlantic ranges.

    Full Text Available Abstract Background Climatic changes during glacial periods have had a major influence on the recent evolutionary history of living organisms, even in temperate forests on islands, where the land was not covered with ice sheets. We investigated the phylogeographical patterns of the weevil Curculio sikkimensis (Curculionidae, a generalist seed predator of Fagaceae plants living in both deciduous oak and evergreen forests of Japan. Its genetic structure was compared to that of another host-specific seed predator, C. hilgendorfi, inhabiting only evergreen forests. Results We examined 921 bp of mitochondrial DNA for 115 individuals collected from 33 populations of C. sikkimensis from 11 plant species of three genera, Quercus, Lithocarpus, and Castanopsis. An analysis of molecular variance revealed that a large proportion (almost 50%, P Conclusion Our results suggest that geology and historical environment have contributed to shaping the present genetic structure of C. sikkimensis. The geographical patterns of genetic differentiation in the Chugoku-Shikoku region observed in the two types of Fagaceae-associated Curculio in this study have also been observed in several plant species growing in warm and cool temperate zones of Japan. The occurrence of this common pattern suggests that deciduous oak and evergreen forests of Japan survived together, or adjacent to each other, in small refugia during glacial ages, in the southwestern and northeastern parts of the main islands, although these two types of forests are presently distributed in cool and warm temperate zones of Japan, respectively.

  13. Host-specific phenotypic plasticity of the turtle barnacle Chelonibia testudinaria: a widespread generalist rather than a specialist.

    Directory of Open Access Journals (Sweden)

    Chi Chiu Cheang

    Full Text Available Turtle barnacles are common epibionts on marine organisms. Chelonibia testudinaria is specific on marine turtles whereas C. patula is a host generalist, but rarely found on turtles. It has been questioned why C. patula, being abundant on a variety of live substrata, is almost absent from turtles. We evaluated the genetic (mitochondrial COI, 16S and 12S rRNA, and amplified fragment length polymorphism (AFLP and morphological differentiation of C. testudinaia and C. patula from different hosts, to determine the mode of adaptation exhibited by Chelonibia species on different hosts. The two taxa demonstrate clear differences in shell morphology and length of 4-6(th cirri, but very similar in arthropodal characters. Moreover, we detected no genetic differentiation in mitochondrial DNA and AFLP analyses. Outlier detection infers insignificant selection across loci investigated. Based on combined morphological and molecular evidence, we proposed that C. testudinaria and C. patula are conspecific, and the two morphs with contrasting shell morphologies and cirral length found on different host are predominantly shaped by developmental plasticity in response to environmental setting on different hosts. Chelonibia testudinaria is, thus, a successful general epibiotic fouler and the phenotypic responses postulated can increase the fitness of the animals when they attach on hosts with contrasting life-styles.

    Determining an adequate training staff size is a vital function of a training manager. Today's training requirements and standards have dictated a more stringent work load than ever before. A trainer's role is more than just providing classroom lectures. In most organizations the instructor must develop programs, lesson plans, exercise guides, objectives, test questions, etc. The tasks of a training organization are never ending and the appropriate resources must be determined and allotted to do the total job. A simple method exists for determining an adequate staff. Although not perfect, this method will provide a realistic approach for determining the needed training staff size. This method considers three major factors: instructional man-hours; non-instructional man-hours; and instructor availability. By determining and adding instructional man-hours and non-instructional man-hours a total man-hour distribution can be obtained. By dividing this by instructor availability a staff size can be determined

    Radiation doses for interventional examinations are generally high and therefore necessitate dose monitoring for patients and staff. Relating the staff dose to a patient dose index, such as dose-area product (DAP), could be quite useful for dose comparisons. In this study, DAP and skin doses of 57 patients, who underwent neuro-interventional examinations, were measured simultaneously with staff doses. Although skin doses were comparable with the literature data, higher DAP values of 215 and 188.6 Gy cm 2 were measured for the therapeutical cerebral and carotid examinations, respectively, owing to the use of biplane system and complexity of the procedure. Mean staff doses for eye, finger and thyroid were measured as 80.6, 77.6 and 28.8 μGy per procedure. The mean effective dose per procedure for the radiologists was 32 μSv. In order to allow better comparisons to be made, DAP normalised doses were also presented. (authors)

    2017-03-13

    Purpose The Department of Health and the National Health Service (NHS) Future Focused Finance (FFF) programme promotes effective engagement between clinical and finance staff. Surveys undertaken by the Department of Health between 2013 and 2015 found few NHS Trusts reported high levels of engagement. The purpose of this paper is to gain a better understanding of current working relationships between NHS clinical and finance professionals and how they might be supported to become more effective. Design/methodology/approach Ipsos MORI were commissioned by the NHS FFF programme to undertake an online survey of NHS clinical and finance staff between June and August 2015. Findings The majority of clinicians had a member of a finance team linked to their speciality or directorate. Clinical and finance professionals have a positive view of joint working preferring face-to-face contact. Clinician's confidence in their understanding of finance was generally good and finance staff felt they had a good understanding of clinical issues. Effective working relationships were facilitated by face-to-face contact, a professional relationship, and the availability of clear, well presented finance and activity data. Research limitations/implications Data protection issues limited the accessibility of the survey team to NHS staff resulting in a relatively low-response rate. Other forms of communication, including social media, were utilised to increase access to the survey. Originality/value The FFF programme is a unique programme aimed at making the NHS finance profession fit for the future. The close partnering work stream brings together the finance and clinical perspective to share knowledge, evidence, training, and to develop good practice and engagement.

    Front-line administrative, academic and clinical teaching staff often find themselves providing pastoral and learning support to students, but they are often not trained for this role, and this aspect of their work is under-acknowledged. Staff participating in an action research study at two medical schools identified common concerns about the personal impact of providing student support, and of the need for professional development to carry out this responsibility. This need is magnified in clinical placement settings that are remote from on-campus services. Informed by participatory action research, brief interactive workshops with multimedia training resources were developed, conducted and evaluated at eight health professional student training sites. These workshops were designed to: (1) be delivered in busy clinical placement and university settings; (2) provide a safe and inclusive environment for administrative, academic and clinical teaching staff to share experiences and learn from each other; (3) be publicly accessible; and (4) promote continued development and roll-out of staff training, adapted to each workplace (see http://www.uws.edu.au/meusupport). The workshops were positively evaluated by 97 participants, with both teaching and administrative staff welcoming the opportunity to discuss and share experiences. Staff supporting health professional students have shared, often unmet, needs for support themselves Staff supporting health professional students have shared, often unmet, needs for support themselves. Participatory action research can be a means for producing and maintaining effective training resources as well as the conditions for change in practice. In our workshops, staff particularly valued opportunities for guided discussion using videos of authentic cases to trigger reflection, and to collaboratively formulate student support guidelines, customised to each site. © 2015 John Wiley & Sons Ltd.

    Full Text Available Abstract Background Although the duties and working conditions of registered, and enrolled nurses have previously been described from different perspectives, they have not been examined from the night nursing aspect. The aim of the study was to describe the night nursing staff's working experiences. Methods The design of the study is qualitative and descriptive. Interviews were conducted with 10 registered and 10 enrolled nurses working as night staff at a Swedish University Hospital. The interview guide was thematic and concerned the content of their tasks, as well as the working conditions that constitute night nursing. In addition, the interviews were transcribed verbatim and analyzed using content analysis. Results The night duties have to be performed under difficult conditions that include working silently in dimmed lighting, and making decisions when fatigue threatens. According to the night staff, its main goals are to provide the patients with rest and simultaneously ensure qualified care. Furthermore, the night nursing staff must prepare the ward for the daytime activities. Conclusion The most important point is the team work, which developed between the registered and enrolled nurses and how necessary this team work is when working at night. In order for nurses working at night to be fully appreciated, the communication between day and night staff in health care organizations needs to be developed. Furthermore, it is important to give the night staff opportunities to use its whole field of competence.

    To compare job satisfaction among nurses, physicians and administrative staff in an emergency department (ED). To analyse the relationship of job satisfaction with demographic and professional characteristics of these personnel. We performed a descriptive, cross-sectional study in an ED in Barcelona (Spain). Job satisfaction was evaluated by means of the Font-Roja questionnaire. Multivariate analysis determined relationship between the overall job satisfaction and the variables collected. Fifty-two nurses, 22 physicians and 30 administrative staff were included. Administrative staff were significantly more satisfied than physicians and nurses: 3.42±0.32 vs. 2.87±0.42 and 3.06±0.36, respectively. Multivariate analysis showed the following variables to be associated with job satisfaction: rotation among the different ED acuity levels (OR: 2.34; 95%CI: 0.93-5.89) and being an administrative staff (OR: 0.27; 95%CI: 0.09-0.80). Nurses and physicians reported greater stress and work pressure than administrative staff and described a worse physical working environment. Interpersonal relationships obtained the highest score among the three groups of professionals. Job satisfaction of nurses and physicians in an ED is lower than that of administrative staff with the former perceiving greater stress and work pressure. Conversely, interpersonal relationships are identified as strength. Being nurse or physician and not rotating among the different ED acuity levels increase dissatisfaction.

    As most end-of-life care is provided by health care providers who are generalists rather than specialists in palliative care, effective communication skills training for generalists is essential. To determine the effect of communication training interventions for generalist palliative care providers on patient-reported outcomes and trainee behaviors. Systematic review from searches of 10 databases to December 2015 (MEDLINE, EMBASE, PsycINFO, ERIC, CINAHL, CENTRAL, Web of Science, ICTRP, CORDIS, and OpenGrey) plus hand searching. Randomized controlled trials of training interventions intended to enhance generalists' communication skills in end-of-life care were included. Two authors independently assessed eligibility after screening, extracted data, and graded quality. Data were pooled for meta-analysis using a random-effects model. PRISMA guidelines were followed. Nineteen of 11,441 articles were eligible, representing 14 trials. Eleven were included in meta-analyses (patients n = 3144, trainees n = 791). Meta-analysis showed no effect on patient outcomes (standardized mean difference [SMD] = 0.10, 95% CI -0.05 to 0.24) and high levels of heterogeneity (chi-square = 21.32, degrees of freedom [df] = 7, P = 0.003; I 2  = 67%). The effect on trainee behaviors in simulated interactions (SMD = 0.50, 95% CI 0.19-0.81) was greater than in real patient interactions (SMD = 0.21, 95% CI -0.01 to 0.43) with moderate heterogeneity (chi-square = 8.90, df = 5, P = 0.11; I 2  = 44%; chi-square = 5.96, df = 3, P = 0.11; I 2  = 50%, respectively). Two interventions with medium effects on showing empathy in real patient interactions included personalized feedback on recorded interactions. The effect of communication skills training for generalists on patient-reported outcomes remains unclear. Training can improve clinicians' ability to show empathy and discuss emotions, at least in simulated consultations. Personalized feedback on recorded patient

    Although identification of risks to dental healthcare workers has been explored in several industrialized nations, very little data is available from developing countries. This paper examines the occupational hazards present in the dental environment and reports survey results concerning attitudes and activities of a group of Nigerian dental care providers. A survey on occupational hazards was conducted among the clinical dental staff at the Dental Hospital of the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife in Osun State, Nigeria. Thirty eight of the forty staff responded, yielding a response rate of 95%. Subject ages ranged from 26 to 56 years with approximately 25% in the 31-46 year old bracket. All of the staff were aware of the occupational exposure to hazards, and the majority had attended seminars/workshops on the subject. Only five staff members (13.2%) owned a health insurance policy and 26 (68.4%) had been vaccinated against Hepatitis B infection. All dentists (24) had been vaccinated compared with only two non-dentists; this relationship was significant (p= 30.07, chi2=0.000). Fourteen members of the clinical staff (36.8%) could recall a sharp injury in the past six months, and the majority (71.1%) had regular contact with dental amalgam. Wearing protective eye goggles was the least employed cross infection control measure, while backache was the most frequently experienced hazard in 47% of the subjects. The need for Hepatitis B vaccinations for all members of the staff was emphasized, and the enforcement of strict cross infection control measures was recommended. The physical activities and body positions that predispose workers to backaches were identified and staff education on the prevention of backaches was provided.

    Full Text Available Introduction: Job life is an important part of a person’s daily life. There are many aspects of a job. A person may be satisfied with one or more aspects of his/her job but at the same time may be unhappy with other things related to the job. Objective: To evaluate the sources of job stress (stressful aspects of work among the staff of a super specialty hospital & to suggest measures to decrease level of job stress. Methodology: Descriptive study employing 381 staff members of a super specialty hospital using a structured personal interview questionnaire consisting of 21 sources of stress. The hospital staff was asked to rate each item according to the extent to which it had contributed to their stress as experienced in their jobs in the past few months on a scale of 0 (not at all,1(a little, 2(quite a bit, 3 (a lot. A global rating of stress was also obtained. Result: The prime sources of stress were found to be underpayment (76%, excessive workload (70.3%, inadequate staff (48.6, & being involved in the emotional distress of patients (46.7%. Conclusion: The staffs of the hospital were in moderate stress due to the prime stressors so adequate measures should be taken to alleviate these stressors. This could be achieved through workload management, job redesign, & by offering occupational health education.

    Full Text Available Purpose. To investigate sleep quality of hospital staff nurses, both by subjective questionnaire and objective measures. Methods. Female staff nurses at a regional teaching hospital in Northern Taiwan were recruited. The Chinese version of the pittsburgh sleep quality index (C-PSQI was used to assess subjective sleep quality, and an electrocardiogram-based cardiopulmonary coupling (CPC technique was used to analyze objective sleep stability. Work stress was assessed using questionnaire on medical worker’s stress. Results. A total of 156 staff nurses completed the study. Among the staff nurses, 75.8% (117 had a PSQI score of ≥5 and 39.8% had an inadequate stable sleep ratio on subjective measures. Nurses with a high school or lower educational degree had a much higher risk of sleep disturbance when compared to nurses with a college or higher level degree. Conclusions. Both subjective and objective measures demonstrated that poor sleep quality is a common health problem among hospital staff nurses. More studies are warranted on this important issue to discover possible factors and therefore to develop a systemic strategy to cope with the problem.

    Full Text Available Attitudes are changing in education globally to promote the open sharing of educational courses and resources. The aim of this study was to explore staff awareness and attitudes toward ‘open educational resources’ (OER as a benchmark for monitoring future progress. Faculty staff (n=6 were invited to participate in semi-structured interviews which facilitated the development of a questionnaire. Staff respondents (n=50 were not familiar with the term OER but had a clear notion of what it meant. They were familiar with open content repositories within the university but not externally. A culture of borrowing and sharing of resources exists between close colleagues, but not further a field, and whilst staff would obtain resources from the Internet they were reticent to place materials there. Drivers for mobilising resources included a strong belief in open education, the ability of OER to enhance individual and institutional reputations, and economic factors. Barriers to OER included confusion over copyright and lack of IT support. To conclude, there is a positive collegiate culture within the faculty, and overcoming the lack of awareness and dismantling the barriers to sharing will help advance the open educational practices, benefiting both faculty staff and the global community.

    The nursing service manager is accountable for the quality of nursing care delivered in the nursing service. It is therefore important that the nursing service manager facilitates staff development in the nursing service. It is not only the nursing service manager's responsibility to make provision for staff development--the nurse also has a responsibility in this regard. He/she should purposefully make an effort to keep up to date with the latest developments. This article focuses on the co-responsibility of the psychiatric nurse and nursing service manager regarding staff development. A model for staff development is described, in accordance with the guidelines of Dickoff, James & Wiedenbach for theory development. An inductive approach was primarily followed to describe the provisional model, after which a literature study was employed to refine and purify the model. This model was exposed to expert evaluation, after which the final model for staff development of psychiatric nurses was described. Recommendations include the testing of certain hypotheses and utilisation of this model in psychiatric nursing practice.

    As most anticancer drugs are cytotoxic, their safe and error-free application is important. We analyzed data from the hematology-oncology ward chemotherapy checklist dated January 13th through February 3rd, 2007 and found accuracy rates for chemotherapy drug usage as low as 68.4%. Possible causes identified for this poor result include incomplete chemotherapy standards protocols, lack of chemotherapy quality control, and insufficient chemotherapy knowledge amongst nursing staff. This project aimed to improve the accuracy of nursing staff in administering chemotherapy and to raise nursing staff knowledge regarding chemotherapy. Our strategies for improvement included completing a chemotherapy standards protocol, establishing a chemotherapy quality-control monitoring system, augmenting chemotherapy training and adding appropriate equipment and staff reminders. After strategies were implemented, accuracy in chemotherapy administration rose to 96.7%. Related knowledge amongst nursing staff also improved from an initial 77.5% to 89.2%. Implementing the recommended measures achieved a significant improvement in the accuracy and quality of chemotherapy administered by nursing personnel.

    This study aimed to evaluate and document the importance of Burnout syndrome among generalist medical doctors (GMD) since no investigation have been carried in Cameroon. Cross-sectional study including 85 GMD using a self-administered questionnaire on socio-demographic characteristics, socioprofessional conditions, Maslach Burnout Inventory - Human Services Survey (MBI-HSS) to evaluate burnout, and Ricci-Gagnon physical activities level metrics. 77 GMD (90.6 %) reported having never heard about burnout. Mean age was 29 years (range 24-42 years). The MBI-HSS revealed that 36 GMD (42.4 %) were victims of burnout, with 27 (31.8 %) at a low level, 8 (9.4 %) moderate and one (1.2 %) severe. Burnout was associated with distance from home to job place (p ⟨ 0.05), strenuous job (p = 0.04), number of children in charge (p = 0.007), number of hospital attended (p = 0.003), number of hours of labor per day (p = 0.0001), conflicts with the hierarchy (p = 0.01), number of guards per month (p = 0.01). Physical activities practice did not showed significant preventive effect on burnout (p = 0.3) (Odds-ratio = 1.45, IC 95 % 0.6, 3.45). Burnout syndrome is not well known among GMD in Douala, though having a high prevalence. Various socio-demographic and socio-professional factors are associated and contribute to increase the level of affect. Burnout seems to be a vicious somato-psycho-somatic disorder. This study did not found a protective or preventive effect of physical activities on burnout.

    To understand the ecological and evolutionary consequences of species interactions in food webs necessitates that interactions are properly identified. Genetic analyses suggest that many supposedly generalist parasitoid species should rather be defined as multiple species with a more narrow diet, reducing the probability that such species may mediate indirect interactions such as apparent competition among hosts. Recent studies showed that the parasitoid Asecodes lucens mediate apparent competition between two hosts, Galerucella tenella and G. calmariensis, affecting both interaction strengths and evolutionary feedbacks. The same parasitoid was also recorded from other species in the genus Galerucella, suggesting that similar indirect effects may also occur for other species pairs. To explore the possibility of such interactions, we sequenced mitochondrial and nuclear genetic markers to resolve the phylogeny of both host and parasitoid and to test the number of parasitoid species involved. We thus collected 139 Galerucella larvae from 8 host plant species and sequenced 31 adult beetle and 108 parasitoid individuals. The analysis of the Galerucella data, that also included sequences from previous studies, verified the five species previously documented as reciprocally monophyletic, but the Bayesian species delimitation for A. lucens suggested 3-4 cryptic taxa with a more specialised host use than previously suggested. The gene data analyzed under the multispecies coalescent model allowed us to reconstruct the species tree phylogeny for both host and parasitoid and we found a fully congruent coevolutionary pattern suggesting that parasitoid speciation followed upon host speciation. Using multilocus sequence data in a Bayesian species delimitation analysis we propose that hymenopteran parasitoids of the genus Asecodes that infest Galerucella larvae constitute at least three species with narrow diet breath. The evolution of parasitoid Asecodes and host Galerucella show

    For generalist parasitoids such as those belonging to the Genus Aphidius, the choice of host species can have profound implications for the emerging parasitoid. Host species is known to affect a variety of life history traits. However, the impact of the host on thermal tolerance has never been studied. Physiological thermal tolerance, enabling survival at unfavourable temperatures, is not a fixed trait and may be influenced by a number of external factors including characteristics of the stress, of the individual exposed to the stress, and of the biological and physical environment. As such, the choice of host species is likely to also have implications for the thermal tolerance of the emerging parasitoid. The current study aimed to investigate the effect of cereal aphid host species (Sitobion avenae, Rhopalosiphum padi and Metopolophium dirhodum) on adult thermal tolerance, in addition to sex and size, of the aphid parasitoids Aphidius avenae, Aphidius matricariae and Aphidius rhopalosiphi. Results revealed no effect of host species on the cold tolerance of the emerging parasitoid, as determined by CT min and Chill Coma, for all parasitoid species. Host species significantly affected the size of the emerging parasitoid for A. rhopalosiphi only, with individuals emerging from R. padi being significantly larger than those emerging from S. avenae, although this did not correspond to a difference in thermal tolerance. Furthermore, a significant difference in the size of male and female parasitoids was observed for A. avenae and A. matricariae, although, once again this did not correspond to a difference in cold tolerance. It is suggested that potential behavioural thermoregulation via host manipulation may act to influence the thermal environment experienced by the wasp and thus wasp thermal tolerance and, in doing so, may negate physiological thermal tolerance or any impact of the aphid host.

    To redefine the practice of rural nurses and describe a model that conceptualises the capabilities and characteristics required in the rural environment. The way in which the practice of rural nurses has been conceptualised is problematic. Definitions of rural nursing have been identified primarily through the functional context of rural health service delivery. The expert generalist term has provided a foundation theory for rural nurses with understandings informed by the scope of practice needed to meet service delivery requirements. However, authors exploring intrinsic characteristics of rural nurses have challenged this definition, as it does not adequately address the deeper, intangible complexities of practice required in the rural context. Despite this discourse, an alternative way to articulate the distinctive nature of rural nursing practice has eluded authors in Australia and internationally. A theoretical paper based on primary research. The development of the model was informed by the findings of a study that explored the nursing practice of managing telephone presentations in rural health services in Victoria, Australia. The study involved policy review from State and Federal governments, nursing and medical professional bodies, and five rural health services; semi-structured interviews with eight Directors of Nursing, seven registered nurses and focus group interviews with eight registered nurses. An ambiguity tolerance model drawn from corporate global entrepreneurship theory was adapted to explain the findings of the study. The adapted model presents capabilities and characteristics used by nurses to successfully manage the ambiguity of providing care in the rural context. Redefining the practice of rural nurses, through an adapted theory of ambiguity tolerance, highlights nursing characteristics and capabilities required in the rural context. This perspective offers new ways of thinking about the work of rural nurses, rural nurse policy, education

    Generalist species can potentially exploit a wide variety of resources, but at the individual level they often show a certain degree of foraging specialization. Specific foraging strategies, however, may increase exposure to environmental contaminants that can alter the cost-benefit balance of consuming particular food items. The Lesser Black-backed Gull (Larus fuscus) is known to opportunistically feed on a wide range of marine and terrestrial prey that differ in contaminant load, such as mercury (Hg) that strongly biomagnifies through the aquatic food web. The hypothesis tested in this study were: i) a predominant use of marine prey by females during egg-formation and by both parents during chick rearing increases the exposure to Hg during embryonic development and chick growth, and ii) this affects parental investment in clutch volume, chick growth and body condition. Total Hg burden and isotopic signatures of carbon (δ 13 C) and nitrogen (δ 15 N) were determined for eggs, down feathers, and primary feathers of L. fuscus chicks collected at a coastal colony in Belgium. As expected, eggs and feathers of chicks from parents with a stable isotope signature that suggested a predominantly marine diet had higher levels of Hg. The use of marine resources by females during the egg-formation period positively correlated to maternal investment in egg size, though entailing the cost of increased Hg-concentrations which in turn negatively affected clutch volume. Furthermore, it is shown that the use of chick down feathers is a suitable matrix to non-lethally estimate Hg concentrations in eggs. Contrary to our expectations, no relationship between Hg exposure and chick growth or chick body condition was found, which may be due the low concentrations found. We conclude that currently Hg contamination does not constitute a risk for development and condition of L. fuscus offspring at the levels currently observed at the Belgian coast.

    The Atomic Energy Control Board conducts a staff assessment of safety at Point Lepreau Generating Station for 1995. On-site Project Officers and Ottawa based specialists monitored the station throughout the year. Point Lepreau operated safely during 1995 which was an unusual year for the station. The station was shut down for a planned five month outage to allow NB Power to complete maintenance on the reactor's pressure tubes. NB Power failed to comply with the terms of the Operating Licence we issue on fourteen occasions in 1995. In addition, NB Power reported an unusually large number of events. None of the events themselves directly affected public safety, if this level of performance continues unchecked, it might result in increased risk from operation in the future. Human error was an important feature of these problems. NB Power had already introduced safety culture training for their staff, but they will need to undertake further work urgently to resolve the problems. Three of Point Lepreau's special safety systems failed to meet their availability targets during 1995. NB Power's safety analysis program progress slowed during 1995, due to the additional workload from the outage. The Point Lepreau's training, quality assurance and safeguards related activities continued to function satisfactorily. They have assigned additional resources to emergency preparedness planning, which should enable them to take a more pro-active approach in this area. 7 tabs., 5 figs

    Staff rotation is defined as a reciprocal exchange of staff between two or more clinical areas for a predetermined period of time. The rationale for introducing a 'Critical Care Nurse Rotation Programme' includes important issues such as improving nurses' knowledge and skills, providing development opportunities, networking, the ability to recruit and retain nurses and the provision of a more versatile and flexible workforce. To gain the understanding of nurses' views and opinions on critical care rotation programmes, evidence was collected by means of questionnaires involving 153 critical care nurses and by undertaking semi-structured interviews with four nurses. On the basis of the responses, a pilot of three Critical Care Nurse Rotation Programmes was introduced. An evaluation of the pilot project assessed participants, supervisors and senior nurses' experience of rotation and revealed very positive experiences being reported. The benefits highlighted included improving clinical skills and experience, improving interdepartmental relationships, heightened motivation and opportunities to network. The disadvantages focused on the operational and managerial issues, such as difficulties maintaining supervision and providing an adequate supernumerary period. Evidence from the survey and pilot study suggests that in the future, providing rotational programmes for critical care nurses would be a valuable strategy for recruitment, retention and developing the workforce.

    Full Text Available In public Organizations staff performance is difficult to measure in absence of overall quantitative performance indicators. There are also the qualitative indicators that give an overview on staff’s motivation, strive, ability, commitment to values, teamwork. These aspects are even less easy to illustrate, in private and public sectors equally. In both cases, measuring staff performance at work, as well as its input on the global performance of the organization is a difficult task which has in practice different approaches. Subsequently, this paper is discussing the system indicators and performance triggers used in International Organizations UN affiliated, in order to adjust staff classification and benefits to their staff’s performance.

The means of the Association to realize its aims are described in Article I.1.3 of the Statutes of the CERN Staff Association. Generally speaking, its aims are “To serve and defend the economic, social, professional and moral interests of its members and all CERN staff“. Usually we deal with professional and social issues (employment conditions, defence of collective or individual rights, promotion of basic research...). But the Association also plays a role of integration (clubs promoting cultural, humanitarian, and sport or offering entertainment, organizing exhibitions and conferences) and it can promote actions to provide its members with material or social advantages (Interfon, commercial offers).

    The medical staff during interventional procedures receives significant doses on their hands, or parts of their body not covered with protective shielding equipment, as they are close to X-rays field. It can be stated, that interventional radiology and cardiology have one of the highest doses among the X-ray diagnostic procedures. The radiologist use X-ray machine directly in the interventional procedures. The occupational dose is measured only by one Kodak film badge worn under the lead apron for the estimation of the effective dose in Hungary. Our lecture presents the results of dose measurements on eye lens, hands, knees using LiF thermoluminescent dosemeters on the medical staff of two Hungarian hospitals. Results suggest that wearing only one film badge (or other dosemeter system) under the lead apron does not provide proper information on the real occupational dose of medical staff.(author)

    Although health policy research should inform policy making, the communication gap between researchers and policy makers limits successful translation. Social media represents a new opportunity to connect researchers and policy makers. Our objective was to assess who Congressional health policy staff follow on a major social media platform. Cross-sectional study. Our study measured Congressional health policy staff's use of Twitter and the types of individuals and organizations they follow. To focus on more influential Twitter accounts, we restricted our sample to those followed by at least 3 individual Congressional staff members. Of the 30,843 accounts followed by the 115 Congressional health policy staff, 1273 were potentially policy-related and followed by 3 or more staff. Of these, few were academically affiliated (2.4%) or explicitly health-related (5.6%) sites; many were general news media sources (50.9%) and political and governmental sources (36.4%). Health-focused accounts were frequently connected to the news media or government rather than academia. Top accounts followed (ie, highest quintile) were most likely to be national news organizations (odds ratio [OR], 5.88; 95% confidence interval [CI], 1.75-19.7) and elected officials (OR, 8.22; 95% CI, 1.75-38.6) compared with advocacy and interest groups. Health-related and academic sources are largely absent from the Twitter conversations with US Congressional health policy staff. Even within social media, traditional and political news media are important information intermediaries that researchers and journals should target to disseminate health policy evidence.

    Food service staff are integral to delivery of quality food in aged care homes yet measurement of their satisfaction is unable to be performed due to an absence of a valid and reliable questionnaire. The aim of this study was to develop and perform psychometric testing for a new Food Service Satisfaction Questionnaire developed in Australia specifically for use by food service staff working in residential aged care homes (Flinders FSSQFSAC). A mixed methods design utilizing both a qualitative (in-depth interviews, focus groups) and a quantitative approach (cross sectional survey) was used. Content validity was determined from focus groups and interviews with food service staff currently working in aged care homes, related questionnaires from the literature and consultation with an expert panel. The questionnaire was tested for construct validity and internal consistency using data from food service staff currently working in aged care homes that responded to an electronic invitation circulated to Australian aged care homes using a national database of email addresses. Construct validity was tested via principle components analysis and internal consistency through Cronbach's alpha. Temporal stability of the questionnaire was determined from food service staff undertaking the Flinders FSSQFSAC on two occasions, two weeks apart, and analysed using Pearson's correlations. Content validity for the Flinders FSSQFSAC was established from a panel of experts and stakeholders. Principle components analysis revealed food service staff satisfaction was represented by 61-items divided into eight domains: job satisfaction (α=0.832), food quality (α=0.871), staff training (α=0.922), consultation (α=0.840), eating environment (α=0.777), reliability (α=0.695), family expectations (α=0.781) and resident relationships (α=0.429), establishing construct validity in all domains, and internal consistency in all (α>0.5) except for "resident relationships" (α=0.429).

    Staff retention presents a common challenge for hospitals nationwide. Mentorship programs have been explored as one method of creating environments that promote staff retention. Successful achievement of nurse competencies identified in the Synergy Model for Patient Care can best be achieved in an environment that encourages and facilitates mentoring. Mentoring relationships in critical care provide the ongoing interactions, coaching, teaching, and role modeling to facilitate nurses' progression along this continuum. Mentoring relationships offer support and professional development for nurses at all levels within an organization as well as an optimistic outlook for the nursing profession.

    STAFF-5 is a dynamic heat-transfer-fluid-flow stress model designed for computerized prediction of the temperature-stress performance of spent LWR fuel assemblies under storage/disposal conditions. Validation of the temperature calculating abilities of this model was performed by comparing temperature calculations under specified conditions to experimental data from the Engine Maintenance and Dissassembly (EMAD) Fuel Temperature Test Facility and to calculations performed by Battelle Pacific Northwest Laboratory (PNL) using the HYDRA-1 model. The comparisons confirmed the ability of STAFF-5 to calculate representative fuel temperatures over a considerable range of conditions, as a first step in the evaluation and prediction of fuel temperature-stress performance

    One third of people diagnosed with PD do not complete treatment and non-completion is associated with poorer clinical outcomes. Equipping staff to be better able to engage this client group is important, and web-based, self-directed learning is a potentially cost-effective way to train staff. This study examined the implementation of a web-based training programme called Readiness Enhancement Management Strategies (REMS) in three types of service. Completion rates were 94.4% in community health services; 92.3% in prison offender health services; and 46.5% in probation services. Staff found the content of REMS acceptable and useful. This study demonstrated that staff in NHS and criminal justice settings can complete REMS, but staff in probation services are challenged by time pressures and limited computer access. Staff at probation sites were less familiar with PD issues compared with the NHS staff. A web-based staff training programme called Readiness Enhancement Management Strategies (REMS) was developed to promote the engagement of people with personality difficulties in treatment. This 'proof of concept' study examined the REMS implementation process, its acceptability and the feasibility of using service data for future evaluation. Staff in six services working with people diagnosed with personality disorder or undiagnosed people with personality difficulties were eligible to participate: two community health services, two prison offender health services and two probation services. Of 92 eligible staff, 74 were available to undertake REMS. These staff completed knowledge and acceptability surveys and rated service user engagement with treatment. The proportion of treatment sessions attended by service users was collected for a 30-week period. REMS completion rates were community - 94.4%, prison - 92.3% and probation - 46.5%. Three quarters of participants rated REMS as 7 out of 10 or higher. All teams were able to provide service data for the study period

  2. A Generalist Herbivore Copes with Specialized Plant Defence: the Effects of Induction and Feeding by Helicoverpa armigera (Lepidoptera: Noctuidae) Larvae on Intact Arabidopsis thaliana (Brassicales) Plants.

    2017-06-01

    Plants of the Brassicaceae are defended from feeding by generalist insects by constitutively-expressed and herbivory-induced glucosinolates (GS). We induced Arabidopsis plants 1, 16 and 24 h prior to allowing neonate larvae of the generalist Helicoverpa armigera to feed on whole plants for 72 h. These plants were subsequently retested with another group of neonates for a further 72 h. We used wild-type A. thaliana Col-0, and mutant lines lacking indolic GS, aliphatic GS or all GS. We hypothesized that larvae would not grow well on defended plants (WT) compared to those lacking GS, and would not grow well if plants had been primed or fed on for longer, due to the expected induced GS. There was survivorship on all lines suggesting H. armigera is a suitable generalist for these experiments. Larvae performed less well on wild-type and no indolic lines than on no aliphatic and no GS lines. Larvae distributed feeding damage extensively in all lines, more so on wild type and no-indolic lines. Contrary to expectations, larvae grew better on plants that had been induced for 1 to 16 h than on un-induced plants suggesting they moved to and selected less toxic plant parts within a heterogeneously defended plant. Performance declined on all lines if plants had been induced for 24 h, or had been fed upon for a further 72 h. However, contrary to expectation, individual and total GS did not increase after these two treatments. This suggests that Arabidopsis plants induce additional (not GS) defenses after longer induction periods.

  3. Effectiveness of annealing blocking primers versus restriction enzymes for characterization of generalist diets: unexpected prey revealed in the gut contents of two coral reef fish species.

    Characterization of predator-prey interactions is challenging as researchers have to rely on indirect methods that can be costly, biased and too imprecise to elucidate the complexity of food webs. DNA amplification and sequencing techniques of gut and fecal contents are promising approaches, but their success largely depends on the ability to amplify the taxonomic array of prey consumed and then match prey amplicons with reference sequences. When little a priori information on diet is available or a generalist predator is targeted, versatile primer sets (also referred to as universal or general primers) as opposed to group- or species-specific primer sets are the most powerful to unveil the full range of prey consumed. However, versatile primers are likely to preferentially amplify the predominant, less degraded predator DNA if no manipulation is performed to exclude this confounding DNA template. In this study we compare two approaches that eliminate the confounding predator template: restriction digestion and the use of annealing blocking primers. First, we use a preliminary DNA barcode library provided by the Moorea BIOCODE project to 1) evaluate the cutting frequency of commercially available restriction enzymes and 2) design predator specific annealing blocking primers. We then compare the performance of the two predator removal strategies for the detection of prey templates using two versatile primer sets from the gut contents of two generalist coral reef fish species sampled in Moorea. Our study demonstrates that blocking primers should be preferentially used over restriction digestion for predator DNA removal as they recover greater prey diversity. We also emphasize that a combination of versatile primers may be required to best represent the breadth of a generalist's diet.

  18. MEDICAL STAFF SCHEDULING USING SIMULATED ANNEALING

    Directory of Open Access Journals (Sweden)

    Ladislav Rosocha

    2015-07-01

    Full Text Available Purpose: The efficiency of medical staff is a fundamental feature of healthcare facilities quality. Therefore the better implementation of their preferences into the scheduling problem might not only rise the work-life balance of doctors and nurses, but also may result into better patient care. This paper focuses on optimization of medical staff preferences considering the scheduling problem.Methodology/Approach: We propose a medical staff scheduling algorithm based on simulated annealing, a well-known method from statistical thermodynamics. We define hard constraints, which are linked to legal and working regulations, and minimize the violations of soft constraints, which are related to the quality of work, psychic, and work-life balance of staff.Findings: On a sample of 60 physicians and nurses from gynecology department we generated monthly schedules and optimized their preferences in terms of soft constraints. Our results indicate that the final value of objective function optimized by proposed algorithm is more than 18-times better in violations of soft constraints than initially generated random schedule that satisfied hard constraints.Research Limitation/implication: Even though the global optimality of final outcome is not guaranteed, desirable solutionwas obtained in reasonable time. Originality/Value of paper: We show that designed algorithm is able to successfully generate schedules regarding hard and soft constraints. Moreover, presented method is significantly faster than standard schedule generation and is able to effectively reschedule due to the local neighborhood search characteristics of simulated annealing.

    The common access to imaging methods based on ionizing radiation requires also radiation protection. The knowledge of ionizing radiation exposure risks among the medical staff is essential for planning diagnostic procedures and therapy. Evaluation of the knowledge of radiation safety during diagnostic procedures among the medical staff. The study consisted of a questionnaire survey. The questionnaire consisted of seven closed-ended questions concerning the knowledge of the effects of exposure to ionizing radiation as well as questions related to responder’s profession and work experience. The study group included a total of 150 individuals from four professional groups: nurses, doctors, medical technicians, support staff. The study was carried out in the three largest hospitals in Gdańsk between July and October 2013. The highest rates of correct answers to questions related to the issue of radiation protection were provided by the staff of radiology facilities and emergency departments with 1–5 years of professional experience. The most vulnerable group in terms of the knowledge of these issues consisted of individuals working at surgical wards with 11–15 years of professional experience. Education in the field of radiological protection should be a subject of periodic training of medical personnel regardless of position and length of service

    2016-11-01

    Caring for people with dementia can be emotionally challenging and is often linked to low job satisfaction and burnout in care staff. Staff training within care settings is potentially valuable in improving well-being and quality of care. This review aimed to (i) establish the impact of training on staff outcomes; (ii) compare the impact of different training approaches; (iii) explore the influence of training intensity; and (iv) explore potential barriers to success. A database search of staff training interventions revealed 207 papers, 188 of which were excluded based on prespecified criteria. Nineteen studies were included and appraised using a quality rating tool. Overall, the studies were found to be of variable quality; however, 16 studies found a significant change following training in at least one staff domain, with knowledge improving most frequently. Approaches focusing on managing challenging behaviours appeared to be the most effective. Training staff can be an effective method of improving well-being, and programmes helping staff to manage challenging behaviour appear to be the most beneficial. There is no clear relationship between training intensity and outcome. Most studies point to the importance of addressing organisational factors as a barrier to change.

    If a parasite is not detected during a survey, one of two explanations is possible: the parasite was truly absent or it was present but not detected. We fit occupancy models to account for imperfect detection when combing fleas (Siphonaptera) from black-tailed prairie dogs (Cynomys ludovicianus) during June-August 2012 in the Vermejo Park Ranch, New Mexico, USA. With the use of detection histories from combing events during monthly trapping sessions, we fit occupancy models for two flea species: Oropsylla hirusta (a prairie dog specialist) and Pulex simulans (a generalist). Detection probability was plague bacterium Yersinia pestis, and even function as a reservoir of Y. pestis between outbreaks.

  9. Mapping Staff Competencies for Information Literacy Interventions

    Directory of Open Access Journals (Sweden)

    Sheila Corrall

    2010-09-01

    Full Text Available Information literacy (IL is a key strategic objective for academic libraries. Many academic librarians are involved in designing, developing and delivering IL programmes, using both classroom teaching and e-learning methods. IL has also become a priority at institutional level and some universities and colleges have formal policies and strategies to integrate and embed IL in the curriculum. IL interventions also happen informally at enquiry points and reference desks, when queries offer ‘teachable moments’ for library staff to help students develop information skills and understanding while solving their information problems. Research shows that such instruction features strongly in both face-to-face and virtual reference transactions, but few IL policies and strategies cover this frontline personalised IL support. Similarly, most discussion of staff training and development for IL education has centred on the teaching roles and pedagogical knowledge of professional librarians, with limited discussion of the competencies needed for frontline interventions by paraprofessionals or assistants. This workshop promotes an inclusive holistic model of IL education and library workforce development. It will investigate the skills and knowledge needed by frontline staff to contribute effectively to the IL mission of academic libraries. It will focus on the learning support needed by students from different educational, social, ethnic and cultural backgrounds, with particular reference to postgraduate students, as a group typifying this diversity. The facilitator will review IL interventions and library staff competencies discussed in the literature. Participants will discuss typical queries or problems presented by different categories of postgraduate students and then identify the skills, knowledge and understanding required by frontline staff to provide an appropriate service response. The skillsets identified will be compared with those of teaching

  10. A "Coach Approach" to Staff Engagement

    Directory of Open Access Journals (Sweden)

    Margaret Macmillan

    2011-11-01

    Full Text Available The speed of change is challenging libraries to redevelop themselves in ways we have never seen before. Rising costs and changing customer expectations are forcing staff to continuously learn new skills, adapt to new technologies and work more closely in collaboration with others in response to this unpredictable environment. At the same time library leaders need to communicate regularly with staff and to motivate them to dialogue with each other about the value of the library service that they provide to the community. A creative approach to building flexibility, resilience and staff engagement has become essential for survival. Coaching is a creative, innovative and effective communications tool that is now considered to be one of the most important ways to encourage employees to continue to learn and develop. Its greatest impact is in building leadership and staff engagement. Communicating with “a coach approach” or coaching mindset is a powerful way for library leaders to connect with others where the flow and exchange is positive and there is a mutual benefit of contribution and collaboration, expanded knowledge and innovation. The basics of fostering “a coach approach” with library staff requires an understanding of the importance of “reframing” one’s personal attitudes and perspectives, appreciating the art of focused listening and the impact of positive acknowledgement, learning to ask the right questions and formulating action plans for continued success. It is a learned skill that requires a commitment to practice but is one that will ultimately demonstrate positive results.

  11. Staff management, training and knowledge management

    International Nuclear Information System (INIS)

    Makino, Hitoshi; Umeki, Hiroyuki; Capouet, M.; Depaus, C.; Berckmans, A.

    2014-01-01

    Staff management/training and knowledge management are organisational issues that are particularly sensitive in long-term projects stretching over decades like the development and operation of a geological repository. The IAEA has already issued several publications that deal with this issue (IAEA, 2006, 2008). Organisational aspects were also discussed in the framework of a topical session organised by the Integration Group for the Safety Case (IGSC) at its annual meeting in 2009 and were regarded as a topic deserving future attention (NEA, 2009a). More recently, the Forum on Stakeholder Confidence (FSC) identified organisational, mission and behavioural features as attributes of confidence and trust (NEA, 2013). They also identified that aspects such as structural learning capacity, high levels of skill and competence in relevant areas, specific management plan, good operating records, transparency and consistency are associated with confidence building in a safety case. These aspects are considerably related to staff training/management and knowledge management. The IGSC has initiated a proposal of study dedicated to staff training/management and knowledge management with the objective to highlight how these recent concerns and the requirements issued by the IAEA are concretely implemented in the national programmes. The goal of this study is to acknowledge the differences of views and needs for staff management and knowledge management at different stages of individual programmes and between implementer and regulator. As a starting point to this study, the JAEA and ONDRAF/NIRAS prepared a draft questionnaire in order to succinctly capture processes and tools that the national organisations have implemented to meet the requirements and address the issues set out in the field of staff and knowledge management. For the purpose of this study, a questionnaire is now under development, which will be presented on the occasion of this symposium with guidance based on a

  12. Engaging Frontline Leaders and Staff in Real-Time Improvement.

    The relationship of staff satisfaction and engagement to organizational success, along with the integral influence of frontline managers on this dimension, is well established in health care and other industries. To specifically address staff engagement, Virginia Mason Medical Center, an integrated, single-hospital health system, developed an approach that involved leaders, through the daily use of standard work for leaders, as well as staff, through a Lean-inspired staff idea system. Kaizen Promotion Office (KPO) staff members established three guiding principles: (1) Staff engagement begins with leader engagement; (2) Integrate daily improve- ment (kaizen) as a habitual way of life not as an add-on; and (3) Create an environment in which staff feel psycho- logically safe and valued. Two design elements--Standard Work for Leaders (SWL) and Everyday Lean Ideas (ELIs) were implemented. For the emergency department (ED), an early adopter of the staff engagement work, the challenge was to apply the guiding principles to improve staff engagement while improving quality and patient and staff satisfaction, even as patient volumes were increasing. Daily huddles for the KPO staff members and weekly leader rounds are used to elicit staff ideas and foster ELIs in real time. Overall progress to date has been tracked in terms of staff satisfaction surveys, voluntary staff turnover, adoption of SWL, and testing and implementation of staff ideas. For example, voluntary turnover of ED staff decreased from 14.6% in 2011 to 7.5% in 2012, and 2.0% in 2013. Organizationwide, at least 800 staff ideas are in motion at any given time, with finished ones posted in an idea supermarket website. A leadership and staff engagement approach that focuses on SWL and on capturing staff ideas for daily problem solving and improvement can contribute to organization success and improve the quality of health care delivery.

  13. A Generalist Looks Back

    Salpeter, Edwin E.

    I fled with my parents from Hitler's Austria to Australia and studied physics at Sydney University. I obtained my Ph.D. in quantum electrodynamics with Rudolf Peierls at Birmingham University and came to Cornell to work with Hans Bethe. I have stayed at Cornell ever since, and I have essentially had only a single job in my whole life, but have switched fields quite often. I worked in nuclear astrophysics and in late-stellar evolution, estimated the Initial Mass Function for star formation and the metal enrichment of the interstellar medium. I suggested black hole accretion as the energy source for quasars, worked on molecule formation on dust grain surfaces, and was involved in 21-cm studies of gas clouds and disk galaxies. I collaborated with my wife on the neurobiology of the neuromuscular junction and with one of my daughters on the epidemiology of tuberculosis.

    Recent cohort studies of randomised controlled trials have provided evidence of within-study selective reporting bias; where statistically significant outcomes are more likely to be more completely reported compared to non-significant outcomes. Bias resulting from selective reporting can impact on meta-analyses, influencing the conclusions of systematic reviews, and in turn, evidence based clinical practice guidelines.In 2006 we received funding to investigate if there was evidence of within-study selective reporting in a cohort of RCTs submitted to New Zealand Regional Ethics Committees in 1998/99. This research involved accessing ethics applications, their amendments and annual reports, and comparing these with corresponding publications. We did not plan to obtain informed consent from trialists to view their ethics applications for practical and scientific reasons. In November 2006 we sought ethical approval to undertake the research from our institutional ethics committee. The Committee declined our application on the grounds that we were not obtaining informed consent from the trialists to view their ethics application. This initiated a seventeen month process to obtain ethical approval. This publication outlines what we planned to do, the issues we encountered, discusses the legal and ethical issues, and presents some potential solutions. Methodological research such as this has the potential for public benefit and there is little or no harm for the participants (trialists) in undertaking it. Further, in New Zealand, there is freedom of information legislation, which in this circumstance, unambiguously provided rights of access and use of the information in the ethics applications. The decision of our institutional ethics committee defeated this right and did not recognise the nature of this observational research. Methodological research, such as this, can be used to develop processes to improve quality in research reporting. Recognition of the potential

  16. Understanding the foundation: the state of generalist search education in library schools as related to the needs of expert searchers in medical libraries.

    Nicholson, Scott

    2005-01-01

    The paper explores the current state of generalist search education in library schools and considers that foundation in respect to the Medical Library Association's statement on expert searching. Syllabi from courses with significant searching components were examined from ten of the top library schools, as determined by the U.S. News & World Report rankings. Mixed methods were used, but primarily quantitative bibliometric methods were used. The educational focus in these searching components was on understanding the generalist searching resources and typical users and on performing a reflective search through application of search strategies, controlled vocabulary, and logic appropriate to the search tool. There is a growing emphasis on Web-based search tools and a movement away from traditional set-based searching and toward free-text search strategies. While a core set of authors is used in these courses, no core set of readings is used. While library schools provide a strong foundation, future medical librarians still need to take courses that introduce them to the resources, settings, and users associated with medical libraries. In addition, as more emphasis is placed on Web-based search tools and free-text searching, instructors of the specialist medical informatics courses will need to focus on teaching traditional search methods appropriate for common tools in the medical domain.

  17. Variation in the diet composition of a generalist predator, the red fox, in relation to season and density of main prey

    2007-05-01

    Diet composition of a generalist predator, the red fox ( Vulpes vulpes) in relation to season (winter or summer) and abundance of multi-annually cyclic voles was studied in western Finland from 1983 to 1995. The proportion of scats (PS; a total of 58 scats) including each food category was calculated for each prey group. Microtus voles (the field vole M. agrestis and the sibling vole M. rossiaemeridionalis) were the main prey group of foxes (PS = 0.55) and they frequently occurred in the scats both in the winter and summer (PSs 0.50 and 0.62, respectively). There was a positive correlation between the PSs of Microtus voles in the winter diet of foxes and the density indices of these voles in the previous autumn. Other microtine rodents (the bank vole Clethrionomys glareolus, the water vole Arvicola terrestris and the muskrat Ondatra zibethicus) were consumed more in winter than in summer. The unusually high small mustelid predation by red foxes (PS = approx. 0.10) in our study area gives qualitative support for the hypothesis on the limiting impact of mammalian predators on least weasel and stoat populations. None of the important prey groups was preyed upon more at low than at high densities of main prey ( Microtus voles). This is consistent with the notion that red foxes are generalist predators that tend to opportunistically subsist on many prey groups. Among these prey groups, particularly hares and birds (including grouse), were frequently used as food by foxes.

    This study examined predictors of staff-supportive organizational culture in assisted living settings. The sample included 294 staff members in 52 facilities. Organizational culture was assessed according to staff perceptions of teamwork, morale, information flow, involvement, supervision, and meetings. Hierarchical linear modeling was used to examine the effects of organizational factors (i.e., facility size, chain membership, ownership, level of care, level of residents' disability) on staff-supportive organizational culture. More staff-supportive culture was associated with smaller facility size, chain membership, and a higher level of care. These findings point to the importance of organizational factors in shaping a staff-supportive organizational culture.

    The term 'mobbing' is defined as antagonistic behaviors with unethical communication directed systematically at one individual by one or more individuals in the workplace. This cross-sectional and descriptive study was conducted for the purpose of determining the mobbing behaviors encountered by nursing school teaching staff in Turkey, its effect on them, and their responses to them. A large percentage (91%) of the nursing school employees who participated in this study reported that they had encountered mobbing behaviors in the institution where they work and 17% that they had been directly exposed to mobbing in the workplace. The academic staff who had been exposed to mobbing behaviors experienced various physiological, emotional and social reactions. They frequently 'worked harder and [were] more organized and worked very carefully to avoid criticism' to escape from mobbing. In addition, 9% of the participants stated that they 'thought about suicide occasionally'.

    2011-10-01

    A hospital that is seeking ways to cut costs without compromising care should resist the temptation to lay off staff and instead make it a priority to improve efficiencies. This approach requires a formal program to identify and analyze all of the hospital's processes. The focus of the analysis should be to determine which activities are being performed efficiently, which are being performed inefficiently, and which are unnecessary. This effort will achieve the greatest success if it is customer-centric.

    Stigmatizing attitudes have been reported in international studies among staff in psychiatry. The authors wanted to investigate if this was the case in Denmark. A survey of attitudes among staff at two psychiatric units in Copenhagen was performed using the Mental Illness: Clinicians' Attitudes scales. The scales have 16 questions to which another four questions were added by the authors. A total of 548 staff members answered the questions (61 doctors and 487 other professionals). The majority of the respondents believed in the possibility of recovery for patients and only a minority associated a high degree of dangerousness with schizophrenia. The cause of the illness was mainly regarded as being biological, but all agreed to a bio-psycho-social aetiological approach. The majority of the respondents believed that the illness was chronic and agreed on the need for staff to also be aware of patients' somatic illness. The doctors did not question their role as "real doctors" or the scientific basis for psychiatry. The majority would not mind working with a colleague with schizophrenia, but about half would hesitate to disclose if they themselves were diagnosed with the illness. Being a woman working in community psychiatry with long experience and participation in a recovery educational programme was associated with less stigmatizing attitudes. The survey showed a relatively low level of stigmatizing attitudes. This runs counter to the results from international investigation. This trend could be interpreted both as a result of a shift towards a more recovery-oriented approach to treatment as well as a reflection of political correctness.

    Dixey, Rachael; Woodall, James

    2011-01-01

    This paper aims to discuss some of the obstacles to implementing policy and strategy related to health promoting prisons. It focuses on the role of prison officers and raises issues concerning their conditions of service, training and organisational culture in a situation where the prison system faces security issues, overcrowding and high levels of ill health among prisoners. This paper emerged as a result of significant overlapping themes between two separate studies conducted by the authors. The paper draws on the authors' qualitative data from these studies. The findings demonstrate the ambiguities and tensions in changing organisational cultures and among prison staff. Alongside the qualitative data, the paper draws on theory regarding policy implementation at the micro-level to show how staff can block or speed up that implementation. Prison officers are an essential part of health promoting prisons, but have been relatively ignored in the discussion of how to create healthier prisons. The contribution that prison staff make to creating health promoting prisons has been under-explored, yet pertinent theory can show how they can be more effectively involved in making changes in organisational culture.

    2016-08-25

    Objective. To develop and test a conceptual model that hypothesized student intention to undertake a higher degree in pharmacy practice research (PPR) would be increased by self-efficacy, outcome expectancy, and the social influence of faculty members. Methods. Cross-sectional surveys were completed by 387 final-year pharmacy undergraduates enrolled in 2012 and 2013. Structural equation modeling was used to explore relationships between variables and intention. Results. Fit indices were good. The model explained 55% of the variation in intention. As hypothesized, faculty social influence increased self-efficacy and indirectly increased outcome expectancy and intention. Conclusion. To increase pharmacy students' orientation towards a career in PPR, faculty members could use their social influence by highlighting PPR in their teaching.

    Most tropical bird species have narrow elevational ranges, likely reflecting climatic specialization. This is consistent with Janzen's Rule, the tendency for mountain passes to be effectively "higher" in the tropics. Hence, those few tropical species that occur across broad elevational gradients (elevational generalists) represent a contradiction to Janzen's Rule. Here, we aim to address the following questions. Are elevational generalists being sundered by diversifying selection along the gradient? Does elevational movement cause these species to resist diversification or specialization? Have they recently expanded, suggesting that elevational generalism is short-lived in geological time? To answer these questions, we tested for differentiation, movement and expansion in four elevational generalist songbird species on the Andean west slope. We used morphology and mtDNA to test for genetic differentiation between high- and low-elevation populations. To test for elevational movements, we measured hydrogen isotope (δ 2 H) values of metabolically inert feathers and metabolically active liver. Morphology differed for House Wren (Troglodytes aedon) and Hooded Siskin (Spinus magellanicus), but not for Cinereous Conebill (Conirostrum cinereum) and Rufous-collared Sparrow (Zonotrichia capensis) respectively. mtDNA was structured by elevation only in Z. capensis. δ 2 H data indicated elevational movements by two tree- and shrub-foraging species with moderate-to-high vagility (C. cinereum and S. magellanicus), and sedentary behaviour by two terrestrial-foraging species with low-to-moderate vagility (T. aedon and Z. capensis). In S. magellanicus, elevational movements and lack of mtDNA structure contrast with striking morphological divergence, suggesting strong diversifying selection on body proportions across the c. 50 km gradient. All species except C. cinereum exhibited mtDNA haplotype variation consistent with recent population expansion across the elevational

    2014-01-01

    Due to the importance of health care organizations with significant responsibility for prevention and care, assessment of job satisfaction among health care staff is essential. Quality of health services will be decreased provided they are not satisfied. This study was a cross-sectional analysis of health care staff in Khomeinishahr (centers, buildings, and networks) If they had at least 6 months work experience, they could enter the study. Data included a two-part questionnaire with a standardized questionnaire, demographic variables, and Smith job descriptive index, which is a questionnaire with six domains. Reliability was obtained for each domain and its validity was reported 0.93. The results showed an overall satisfaction score averages 43.55 ± 12.8 (from 100). Job satisfaction score was not significantly different between the sexes. However, within the current attitude toward job satisfaction, men scores was better than women (P = 0.001). Highest score in job satisfaction was related to relationships with colleagues and lowest score was related to the income, benefits, and job promotion. The more the years of work, the less the job satisfaction was. The attitude toward the current job had a direct relationship with income (P = 0.01). There was a significant inverse relationship between educational level and job satisfaction in domains promotion, income, and benefits (P = 0.01). The staff with higher education levels was less satisfied with income and job promotion qualification. Managers should focus on job qualification to increase job satisfaction and improve the quality of work.

    A study to estimate the number of nursing staff required for neonatal nursing was undertaken. Certain nursing tasks, such as transporting any infant, caring for the dying infant, and looking after the very unstable infant required continuous attention by one nurse (5.5 whole time equivalent (wte) nurses for each cot). The stable ventilated infant required 10.5 nursing hours each day-that is, 2.4 wte/cot. Infants with intravenous infusions, but not ventilated, required only slightly less nursi...

    For many years, the Staff Association has supported the demand for the creation of a crèche for the children of CERN staff. Several studies have been carried out without leading to a concrete plan. The fact that the CERN population is getting younger and the shortage of local facilities have led to a more urgent demand for this type of social service over the past few years. Furthermore, the Equal Opportunities Panel had already recommended that crèche places be made available.

    2018-05-01

    Generalist mental health professionals are inadequately equipped to meet the rights of people with intellectual disability. A better understanding of the attributes of effective professionals may assist in the development of workforce capacity in this area. Twenty-eight family/support persons of people with intellectual disability participated in four focus groups. Thematic analysis was undertaken applying the Intellectual Disability Mental Health Core Competencies Framework. Participants described attributes that aligned with current professional expectations such as working together and new attributes such as differentiating between behaviour and mental health. An unexpected finding was the need for professionals to be able to infer meaning by interpreting multiple sources of information. Participants also wanted professionals to acknowledge their professional limitations and seek professional support. Family/support persons identified a range of attributes of effective mental health professionals to support people with intellectual disability. Further research is necessary, particularly from the perspective of people with intellectual disability. © 2017 John Wiley & Sons Ltd.

    Full Text Available Objective: In this paper, we aimed to investigate the job satisfaction levels of all the academic staff in Trakya University, along with their socioeconomic features.Material and Methods: We used a questionnaire including the Minnesota Satisfaction Questionnaire Short Form. Frequency tables, cross tabulations, Pearson Chi-square, Exact Chi-square, Kruskal-Wallis, Dunn’s Multiple Comparison and Chi-squared Automatic Interaction Detector (CHAID tests were used for statistical analysis.Results: The mean age of 560 participants was 33.86±7.33 years, of whom 47% (n=263 were female and 53% (n=297 male. Of the participants, the mean levels were 63.06±10.96 for general, 44.79±7.49 for intrinsic, and 18.27±4.64 for extrinsic job satisfaction. 85.4% of the academic staff (n=478 had a moderate level of satisfaction, whereas 14.6% (n=82 had a higher level. There was a significant relationship between income and job satisfaction levels. With the CHAID analysis, it was determined that job satisfaction had a relationship with age, educational status, total years of service and years of service in the current department. Conclusion: Job satisfaction can reflect the general emotional status of employees. It has a greater importance for the jobs that can affect the extraoccupational lives directly and require constant devotion. Employers should take some measures to increase job satisfaction in order to improve efficiency.

  15. Staff nurse perceptions of the impact of mentalization-based therapy skills training when working with borderline personality disorder in acute mental health: a qualitative study.

    2015-10-01

    People diagnosed with borderline personality disorder (BPD) are highly prevalent in acute mental health wards, with staff nurses identifying a challenge in working with people who can be significantly distressed. This has contributed to a negative stereotype verging on stigmatization. Mentalization-based therapy (MBT) is a psychological therapy which has been shown to be of benefit to people with a diagnosis of BPD, yet it has been utilized and evaluated only in partial hospitalization and outpatient settings. Despite this, most people diagnosed with BPD will continue to be treated in generic inpatient settings such as acute mental health. Mentalization-based therapy skills training (MBT-S) is a new and cost-effective 2-day workshop aiming to provide generalist practitioners with MBT skills for use in generic settings. This study aimed to capture staff perceptions of the impact of MBT-S on their practice when working with people with a diagnosis of BPD in acute mental health. Through two focus groups, this study assessed the perceptions of nine staff nurses. An interpretive phenomenological approach was utilized in data analysis. Participants found the approach easy to grasp, improving of consistency between staff and flexible in its use in planned or 'off the cuff' discussions. MBT-S promoted empathy and humane responses to self-harm, impacted on participants ability to tolerate risk and went some way to turning the negative perception of BPD through changing the notion of patients as 'deliberately difficult'. Staff felt empowered and more confident in working with people with a diagnosis of BPD. The positive implication for practice was the ease in which the approach was adopted and participants perception of MBT-S as an empowering skill set which also contributed to attitudinal change. In acute mental health environments, which may not have the resources to provide long-term structured treatments to patients, MBT-S could be viewed as ideal as participants

    Holobionts have a digestive microbiota with catabolic abilities allowing the degradation of complex dietary compounds for the host. In terrestrial herbivores, the digestive microbiota is known to degrade complex polysaccharides from land plants while in marine herbivores, the digestive microbiota is poorly characterized. Most of the latter are generalists and consume red, green, and brown macroalgae, three distinct lineages characterized by a specific composition in complex polysaccharides, which represent half of their biomass. Subsequently, each macroalga features a specific epiphytic microbiota, and the digestive microbiota of marine herbivores is expected to vary with a monospecific algal diet. We investigated the effect of four monospecific diets (Palmaria palmata, Ulva lactuca, Saccharina latissima, Laminaria digitata) on the composition and specificity of the digestive microbiota of a generalist marine herbivore, the abalone, farmed in a temperate coastal area over a year. The microbiota from the abalone digestive gland was sampled every 2 months and explored using metabarcoding. Diversity and multivariate analyses showed that patterns of the microbiota were significantly linked to seasonal variations of contextual parameters but not directly to a specific algal diet. Three core genera: Psychrilyobacter, Mycoplasma, and Vibrio constantly dominated the microbiota in the abalone digestive gland. Additionally, a less abundant and diet-specific core microbiota featured genera representing aerobic primary degraders of algal polysaccharides. This study highlights the establishment of a persistent core microbiota in the digestive gland of the abalone since its juvenile state and the presence of a less abundant and diet-specific core community. While composed of different microbial taxa compared to terrestrial herbivores, the digestive gland constitutes a particular niche in the abalone holobiont, where bacteria (i) may cooperate to degrade algal polysaccharides to

  17. Systematic analysis of phloem-feeding insect-induced transcriptional reprogramming in Arabidopsis highlights common features and reveals distinct responses to specialist and generalist insects.

    Phloem-feeding insects (PFIs), of which aphids are the largest group, are major agricultural pests causing extensive damage to crop plants. In contrast to chewing insects, the nature of the plant response to PFIs remains poorly characterized. Scrutiny of the literature concerning transcriptional responses of model and crop plant species to PFIs reveals surprisingly little consensus with respect to the transcripts showing altered abundance following infestation. Nevertheless, core features of the transcriptional response to PFIs can be defined in Arabidopsis thaliana. This comparison of the PFI-associated transcriptional response observed in A. thaliana infested by the generalists Myzus persicae and Bemisia tabaci with the specialist Brevicoryne brassicae highlights the importance of calcium-dependent and receptor kinase-associated signalling. We discuss these findings within the context of the complex cross-talk between the different hormones regulating basal immune response mechanisms in plants. We identify PFI-responsive genes, highlighting the importance of cell wall-associated kinases in plant-PFI interactions, as well as the significant role of kinases containing the domain of unknown function 26. A common feature of plant-PFI interaction is enhanced abundance of transcripts encoding WRKY transcription factors. However, significant divergence was observed with respect to secondary metabolism dependent upon the insect attacker. Transcripts encoding enzymes and proteins associated with glucosinolate metabolism were decreased following attack by the generalist M. persicae but not by the specialist B. brassicae. This analysis provides a comprehensive overview of the molecular patterns associated with the plant response to PFIs and suggests that plants recognize and respond to perturbations in the cell wall occurring during PFI infestation. © The Author 2014.

  18. The roles of geography and founder effects in promoting host-associated differentiation in the generalist bogus yucca moth Prodoxus decipiens.

    There is ample evidence that host shifts in plant-feeding insects have been instrumental in generating the enormous diversity of insects. Changes in host use can cause host-associated differentiation (HAD) among populations that may lead to reproductive isolation and eventual speciation. The importance of geography in facilitating this process remains controversial. We examined the geographic context of HAD in the wide-ranging generalist yucca moth Prodoxus decipiens. Previous work demonstrated HAD among sympatric moth populations feeding on two different Yucca species occurring on the barrier islands of North Carolina, USA. We assessed the genetic structure of P. decipiens across its entire geographic and host range to determine whether HAD is widespread in this generalist herbivore. Population genetic analyses of microsatellite and mtDNA sequence data across the entire range showed genetic structuring with respect to host use and geography. In particular, genetic differentiation was relatively strong between mainland populations and those on the barrier islands of North Carolina. Finer scale analyses, however, among sympatric populations using different host plant species only showed significant clustering based on host use for populations on the barrier islands. Mainland populations did not form population clusters based on host plant use. Reduced genetic diversity in the barrier island populations, especially on the derived host, suggests that founder effects may have been instrumental in facilitating HAD. In general, results suggest that the interplay of local adaptation, geography and demography can determine the tempo of HAD. We argue that future studies should include comprehensive surveys across a wide range of environmental and geographic conditions to elucidate the contribution of various processes to HAD. © 2014 European Society For Evolutionary Biology.
