On November 20, 1991, the National Oceanic Atmospheric Administration listed Snake River sockeye salmon Oncorhynchus nerka as endangered under the Endangered Species Act of 1973. In 1991, the Shoshone-Bannock Tribes (SBT) and Idaho Department of Fish and Game (IDFG) initiated the Snake River Sockeye Salmon Captive Broodstock Program to conserve and rebuild populations in Idaho. Restoration efforts are focused on Redfish, Pettit, and Alturas lakes within the Sawtooth Valley. The first release of hatchery-produced adults occurred in 1993. The first release of juvenile sockeye salmon from the captive broodstock program occurred in 1994. In 1999, the first anadromous adult returnsmore » from the captive broodstock program were recorded when six jacks and one jill were captured at the IDFG Sawtooth Fish Hatchery. In 2007, progeny from the captive broodstock program were released using four strategies: (1) eyed-eggs were planted in Pettit Lake in November; (2) age-0 presmolts were released to Alturas, Pettit, and Redfish lakes in October; (3) age-1 smolts were released into Redfish Lake Creek and the upper Salmon River in May; and (4) hatchery-produced adult sockeye salmon were released to Redfish Lake for volitional spawning in September. Oncorhynchus nerka population monitoring was conducted on Redfish, Alturas, and Pettit lakes using a midwater trawl in September 2007. Population abundances were estimated at 73,702 fish for Redfish Lake, 124,073 fish for Alturas Lake, and 14,746 fish for Pettit Lake. Angler surveys were conducted from May 26 through August 7, 2007 on Redfish Lake to estimate kokanee harvest. On Redfish Lake, we interviewed 102 anglers and estimated that 56 kokanee were harvested. The calculated kokanee catch rate was 0.03 fish/hour for each kokanee kept. The juvenile out-migrant trap on Redfish Lake Creek was operated from April 14 to June 13, 2007. We estimated that 5,280 natural origin and 14,256 hatchery origin sockeye salmon smolts out

The Grande Ronde Basin Spring Chinook Salmon Captive Broodstock Program is designed to rapidly increase numbers of Chinook salmon in stocks that are in imminent danger of extirpation in Catherine Creek (CC), Lostine River (LR) and upper Grande Ronde River (GR). Natural parr are captured and reared to adulthood in captivity, spawned (within stocks) and their progeny reared to smoltification before being released into the natal stream of their parents. This program is co-managed by ODFW, National Marine Fisheries Service, Nez Perce Tribe and Confederated Tribes of the Umatilla Indian Reservation. Presmolt rearing was initially conducted at Lookingglass Fish Hatcherymore » (LFH) but parr collected in 2003 and later were reared at Wallowa Fish Hatchery (WFH). Post-smolt rearing is conducted at Bonneville Fish Hatchery (BOH - freshwater) and at Manchester Research Station (MRS - saltwater). The CC and LR programs are being terminated, as these populations have achieved the goal of a consistent return of 150 naturally spawning adults, so the 2005 brood year was the last brood year collected for theses populations. The Grande Ronde River program continued with 300 fish collected each year. Currently, we are attempting to collect 150 natural parr and incorporate 150 parr collected as eggs from females with low ELISA levels from the upper Grande Ronde River Conventional Hatchery Program. This is part of a comparison of two methods of obtaining fish for a captive broodstock program: natural fish vs. those spawned in captivity. In August 2007, we collected 152 parr (BY 2006) from the upper Grande Ronde River and also have 155 Grande Ronde River parr (BY 2006) that were hatched from eyed eggs at LFH. During 2008, we were unable to collect natural parr from the upper Grande Ronde River. Therefore, we obtained 300 fish from low ELISA females from the upper Grande Ronde River Conventional Program. In October 2008 we obtained 170 eyed eggs from the upper Grande Ronde river

In 2003, progeny from the captive broodstock program were released using three strategies: eyed-eggs were planted in Pettit and Alturas lakes in November and December, age-0 presmolts were released to Alturas, Pettit, and Redfish lakes in October, and hatchery-produced adult sockeye salmon were released to Redfish Lake for volitional spawning in September. Oncorhynchus nerka population monitoring was conducted on Redfish, Alturas, and Pettit lakes using a midwater trawl in September 2003. Age-0 through age-4 O. nerka were captured in Redfish Lake, and population abundance was estimated at 81,727 fish. Age-0 through age-3 O. nerka were captured in Alturas Lake, and population abundance was estimated at 46,234 fish. Age-0 through age-3 O. nerka were captured in Pettit Lake, and population abundance was estimated at 11,961 fish. Angler surveys were conducted from May 25 through August 7, 2003 on Redfish Lake to estimate kokanee harvest. On Redfish Lake, we interviewed 179 anglers and estimated that 424 kokanee were harvested. The calculated kokanee catch rate was 0.09 fish/hour.

Several bacteriological surveys were performed from 1994 to 1996 at different Litopenaeus vannamei hatcheries (in Ecuador) and shrimp farms (in Mexico). Samples were taken from routine productions of healthy and diseased L. vannamei larvae, postlarvae, and their culture environment and from healthy and diseased juveniles and broodstock. In Ecuador, the dominant bacterial flora associated with shrimp larvae showing symptoms of zoea 2 syndrome, mysis mold syndrome, and bolitas syndrome has been determined. Strains were characterized by Biolog metabolic fingerprinting and identified by comparison to a database of 850 Vibrio type and reference strains. A selection of strains was further genotypically fine typed by AFLP. Vibrio alginolyticus is predominantly present in all larval stages and is associated with healthy nauplius and zoea stages. AFLP genetic fingerprinting shows high genetic heterogeneity among V. alginolyticus strains, and the results suggest that putative probiotic and pathogenic strains each have specific genotypes. V. alginolyticus was found to be associated with larvae with the zoea 2 syndrome and the mysis mold syndrome, while different Vibrio species (V. alginolyticus and V. harveyi) are associated with the bolitas syndrome. V. harveyi is associated with diseased postlarvae, juveniles, and broodstock. The identities of the strains identified as V. harveyi by the Biolog system could not be unambiguously confirmed by AFLP genomic fingerprinting. Vibrio strain STD3-988 and one unidentified strain (STD3-959) are suspected pathogens of only juvenile and adult stages. V. parahaemolyticus, Photobacterium damselae, and V. mimicus are associated with juvenile and adult stages. PMID:10347048

The black-lip pearl oyster (Pinctada margaritifera) is cultured extensively to produce black pearls, especially in French Polynesia atoll lagoons. This aquaculture relies on spat collection, a process that experiences spatial and temporal variability and needs to be optimized by understanding which factors influence recruitment. Here, we investigate the sensitivity of P. margaritifera larval dispersal to both physical and biological factors in the lagoon of Ahe atoll. Coupling a validated 3D larval dispersal model, a bioenergetics larval growth model following the Dynamic Energy Budget (DEB) theory, and a population dynamics model, the variability of lagoon-scale connectivity patterns and recruitment potential is investigated. The relative contribution of reared and wild broodstock to the lagoon-scale recruitment potential is also investigated. Sensitivity analyses pointed out the major effect of the broodstock population structure as well as the sensitivity to larval mortality rate and inter-individual growth variability to larval supply and to the subsequent settlement potential. The application of the growth model clarifies how trophic conditions determine the larval supply and connectivity patterns. These results provide new cues to understand the dynamics of bottom-dwelling populations in atoll lagoons, their recruitment, and discuss how to take advantage of these findings and numerical models for pearl oyster management.

The Nez Perce Tribe (NPT), through funding provided by the Bonneville Power Administration (BPA), has implemented a Chinook salmon supplementation program (250,000 smolts) on the Lostine River, a tributary to the Grande Ronde River of Oregon. The Grande Ronde Endemic Spring Chinook Salmon Supplementation project, which involves supplementation of the Upper Grande Ronde River and Catherine Creek in addition to the Lostine River, was established to prevent extirpation and increase the number of threatened Snake River spring/summer Chinook salmon (Oncorhynchus tshawytscha) returning to the Grande Ronde River. This report covers the seventh season (1997-2003) of adult Chinook salmon broodstock collectionmore » in the Lostine River and the fifth season (1999-2003) of acclimating the resultant progeny. Production of Lostine River spring Chinook salmon smolts currently occurs at Lookingglass Fish Hatchery (LGH). The Lostine River supplementation program utilizes two strategies to obtain egg source for production of smolts for supplementation: captive broodstock and conventional broodstock. The captive broodstock strategy involves (1) capture of natural juvenile spring Chinook salmon smolts from the Lostine River, (2) rearing those to adult and spawning them, and (3) rearing the resultant progeny for eventual acclimation and release back into the Lostine River. The conventional broodstock strategy involves (1) capture of natural and hatchery origin adults returning to the Lostine River, (2) holding those adults and spawning them, and (3) rearing the resultant progeny for acclimation and release back into the Lostine River. This report focuses on (1) the trapping and collection of adult spring Chinook salmon that return to the Lostine River, which provides the broodstock source for the conventional strategy and (2) the acclimation and release of juvenile spring Chinook salmon produced from the captive broodstock and conventional broodstock strategies. In 2003, acclimation

The success of captive broodstock programs depends on high in-culture survival, appropriate development of the reproductive system, and the behavior and survival of cultured salmon after release, either as adults or juveniles. Continuing captive broodstock research designed to improve technology is being conducted to cover all major life history stages of Pacific salmon. Current velocity in rearing vessels had little if any effect on reproductive behavior of captively reared steelhead. However, males and females reared in high velocity vessels participated a greater number of spawning events than siblings reared in low velocity tanks. Observations of nesting females and associated malesmore » in a natural stream (Hamma Hamma River) were consistent with those observed in a controlled spawning channel. DNA pedigree analyses did not reveal significant differences in the numbers of fry produced by steelhead reared in high and low velocity vessels. To determine the critical period(s) for imprinting for sockeye salmon, juvenile salmon are being exposed to known odorants at key developmental stages. Subsequently they will be tested for development of long-term memories of these odorants. In 2002-2003, the efficacy of EOG analysis for assessing imprinting was demonstrated and will be applied in these and other behavioral and molecular tools in the current work plan. Results of these experiments will be important to determine the critical periods for imprinting for the offspring of captively-reared fish destined for release into natal rivers or lakes. By early August, the oocytes of all of Rapid River Hatchery chinook salmon females returning from the ocean had advanced to the tertiary yolk globule stage; whereas, only some of the captively reared Lemhi River females sampled had advanced to this stage, and the degree of advancement was not dependent on rearing temperature. The mean spawning time of captive Lemhi River females was 3-4 weeks after that of the Rapid River

The efficacy of captive broodstock programs depends on high in-culture survival and the fitness of cultured salmon after release, either as adults or juveniles. Continuing captive broodstock research designed to improve technology is being conducted to cover all major life history stages of Pacific salmon. The following summarizes some of the work performed and results from the FY 2001 performance period: (1) The incidence of male maturation of age-1 chinook salmon was significantly reduced by reducing growth in the first year of rearing. (2) Experimentally manipulated growth rates of captively-reared coho salmon had significant effects on female maturation rate, eggmore » size, and fecundity, and the effects were stage-specific (i.e., pre-smolt vs. post-smolt). (3) A combination of Renogen and MT239 vaccination of yearling chinook salmon given an acute R. salmoninarum challenge had a significantly longer survival time than the mock-vaccinated group. The survival time was marginally higher than was seen in acutely challenged fish vaccinated with either Renogen or MT239 alone and suggests that a combination vaccine of Renogen and MT239 may be useful as both a prophylactic and therapeutic agent against BKD. (4) Full-sib (inbred) groups of chinook salmon have thus far exhibited lower ocean survival than half-sib and non-related groups. Effects of inbreeding on fluctuating asymmetry did not follow expected patterns. (5) Sockeye salmon were exposed to specific odorants at either the alevin/emergent fry stage or the smolt stage to determine the relative importance of odorant exposure during key developmental periods and the importance of exposure duration. (6) Experimental studies to determine the effects of exercise conditioning on steelhead reproductive behavior and the effects of male body size on chinook salmon fertilization success during natural spawning were completed.« less

Most giant groupers in the market are derived from inbred stock. Inbreeding can cause trait depression, compromising the animals' fitness and disease resistance, obligating farmers to apply increased amounts of drugs. In order to solve this problem, a pedigree classification method is needed. Here, microsatellite and mitochondrial DNA were used as genetic markers to analyze the genetic relationships among giant grouper broodstocks. The 776-bp fragment of high polymorphic mitochondrial D-loop sequence was selected for measuring sibling relatedness. In a sample of 118 giant groupers, 42 haplotypes were categorized, with nucleotide diversity (π) of 0.00773 and haplotype diversity (HD) of 0.983. Furthermore, microsatellites were used for investigation of parentage. Six out of 33 microsatellite loci were selected as markers based on having a high number of alleles and compliance with Hardy-Weinberg equilibrium. Microsatellite profiles based on these loci provide high variability with low combined non-exclusion probability, permitting practical use in aquaculture. The method described here could be used to improve grouper broodstock management and lower the chances of inbreeding. This approach is expected to lead to production of higher quality groupers with higher disease resistance, thereby reducing the need for drug application.

The present trial was conducted with starry flounder Platichthys stellatus broodstock to evaluate the effects of dietary vitamin A, ascorbic acid, and α-tocopherol on the gonadal development and reproductive performance. 8 000 IU/kg diet vitamin A (VA group), 500 mg/kg diet ascorbic acid (Vcpp group), or 250 mg/kg diet α-tocopherol (α-TA group) was added into basal diet to create 3 vitamin experimental diets, respectively. Each diet was fed to 450 starry flounder broodstock for 104 days. Samples were collected weekly. The gonadosomatic index (GSI) of 3 vitamin experimental groups first decreased and then increased. Maximum GSI of Vcpp group was higher than that of α-TA group but lower than that of VA group. The spawning periods of 3 vitamin experimental groups lasted 49, 56, and 45 days, respectively. No mature eggs were observed in the control group during the trial. The absolute fecundity (AF) and relative fecundity (RF) of α-TA group was higher than that of Vcpp group but lower than that of VA group. The results suggest that different vitamins play different roles in the fish reproductive process. Vitamin A stimulated the maturation of the ovary, ascorbic acid prolonged the spawning period, and α-tocopherol affected the development of the eggs.

This document examines the potential of employing a series of lake management strategies to enhance production of endangered Snake River sockeye salmon (Oncorhynchus nerka) in its historical nursery lakes in central Idaho. A combination of limnological sampling, experimentation, and simulation modeling was used to assess effects of lake fertilization and kokanee reduction on growth and survival of juvenile sockeye salmon. Juvenile sockeye salmon from a broodstock of this endangered species are being introduced into the lakes from 1995 to 1998. Results of our analyses indicated that several lakes were suitable for receiving broodstock progeny. Field experimentation and simulation modeling indicatedmore » that lake fertilization, coupled with a program of kokanee reduction, provided the management option most likely to enhance the survival of stocked juvenile sockeye salmon. Simulation models that encompass physiological requirements, ecological interactions, and life-history consequences could be used as templates to help develop recovery plans for other endangered fishes. 4 figs., 2 tabs.« less

Genetic and demographic implications of aquaculture in white sturgeon (Acipenser transmontanus)conservation

2005-01-01

This study uses a genetic individual-based model of white sturgeon (Acipenser transmontanus) populations in a river to examine the genetic and demographic trade-offs associated with operating a conservation hatchery. Simulation experiments evaluated three management practices: (i) setting quotas to equalize family contributions in an effort to prevent genetic swamping, (ii) an adaptive management scheme that interrupts stocking when introgression exceeds a specified threshold, and (iii) alternative broodstock selection strategies that influence domestication. The first set of simulations, designed to evaluate equalizing the genetic contribution of families, did not show the genetic benefits expected. The second set of simulations showed thatmore » simulated adaptive management was not successful in controlling introgression over the long term, especially with uncertain feedback. The third set of simulations compared the effects of three alternative broodstock selection strategies on domestication for hypothetical traits controlling early density-dependent survival. Simulated aquaculture selected for a density-tolerant phenotype when broodstock were taken from a genetically connected population. Using broodstock from an isolated population (i.e., above an upstream barrier or in a different watershed) was more effective at preventing domestication than using wild broodstock from a connected population.« less

Fatty Acid Profile of Neutral and Polar Lipid Fraction of Wild Eggs and Hatchlings from Wild and Captive Reared Broodstock of Octopus vulgaris

The culture of Octopus vulgaris is constrained by unsolved problems in paralarvae rearing, mainly associated to the unknown nutritional requirements of this species in early stages. In this article we studied the fatty acid profile (total, neutral, and polar lipid fractions) in wild eggs and wild hatchlings, collected in Gran Canaria (SW) (Spain) with artificial dens, in comparison to hatchlings obtained in captivity from broodstock fed on trash fish species. Total lipids were 11.5–13.5% dw, with the polar fraction representing a 70.6–75.5% of total lipid, with lower values in wild hatchling in comparison with captive ones. Docosahexaenoic acid (DHA) was the main component in neutral and polar fatty acid profile in all samples, underlying its importance in this species. Decreasing levels of saturates and arachidonic acid (ARA) from wild eggs to hatchlings, mainly associated to the polar fraction, suggest their use during embryonic development. In hatchlings, increasing levels of oleic acid in the neutral fraction and eicosapentaenoic acid (EPA) in the polar fraction, suggests their importance in hatchlings quality. Wild hatchlings showed in the polar fraction higher oleic acid and ARA, and lower DHA/ARA and EPA/ARA ratios in comparison with captive hatchlings, suggesting a difference in paralarvae nutritional status. These results suggest the importance of n-3 highly unsaturated fatty acids (HUFA), oleic acid, and ARA, presented in the adequate lipid fraction, in the diet of broodstock and paralarvae of O. vulgaris.

The aims of this study were to identify genes involved in reproduction and lipid pathway metabolism in Penaeus monodon and correlate their expression with reproductive performance. Samples of the hepatopancreas and ovaries were obtained from a previous study of the reproductive performance of wild and domesticated P. monodon broodstock. Total mRNA from the domesticated broodstock was used to create two next generation sequencing cDNA libraries enabling the identification of 11 orthologs of key genes in reproductive and nutritional metabolic pathways in P. monodon. These were identified from the library of de novo assembled contigs, including the description of 6 newly identified genes. Quantitative RT-PCR of these genes in the hepatopancreas prior to spawning showed that the domesticated mature females significantly showed higher expression of the Pm Elovl4, Pm COX and Pm SUMO genes. The ovaries of domesticated females had a significantly decreased expression of the Pm Elovl4 genes. In the ovaries of newly spawned females, a significant correlation was observed between hepatosomatic index and the expression of Pm FABP and also between total lipid content and the expression of Pm CYP4. Although not significant, the highest levels of correlation were found between relative fecundity and Pm CRP and Pm CYP4 expression, and between hatching rate and Pm Nvd and Pm RXR expression. This study reports the discovery of genes involved in lipid synthesis, steroid biosynthesis and reproduction in P. monodon. These results indicate that genes encoding enzymes involved in lipid metabolism pathways might be potential biomarkers to assess reproductive performance. Copyright © 2015 Elsevier B.V.

Converting science to policy through stakeholder involvement: an analysis of the European Marine Strategy Directive.

PubMed

Fletcher, Stephen

2007-12-01

The Marine Strategy Directive requires European Union Member States to develop science-based marine strategies with the involvement of stakeholders, in order that Europe's marine environment reaches 'good environmental status' by 2021. The scientific requirements of marine strategies are clearly defined within the Directive, however, the requirements related to stakeholder involvement are not. This paper presents a critical analysis of the provisions for stakeholder involvement with in the Marine Strategy Directive. In particular, the paper is focused upon the definition of stakeholder, the sequencing of involvement, and the form and purpose of involvement. The critique is set within an evaluative framework that considers policy-making to be a social process, rather than a purely scientific one. It is concluded that the Marine Strategy Directive lacks coherency with respect to stakeholder involvement which may perpetuate the traditional tension between marine science and policy. This in turn may compromise the ability of the Directive to protect Europe's marine environment.

"Research to Improve the Efficacy of Captive Broodstock Programs and Advance Hatchery Reform Throughout the Columbia River Basin." [from the Abstract], 2007-2008 Annual Progress Report.

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

Berejikian, Barry A.

This project was developed to conduct research to improve the efficacy of captive broodstock programs and advance hatchery reform throughout the Columbia river basin. The project has three objectives: (1) maintain adaptive life history characteristics in Chinook salmon, (2) improve imprinting in juvenile sockeye salmon, and (3) match wild phenotypes in Chinook and sockeye salmon reared in hatcheries. A summary of the results are as follows: Objective 1: Adult and jack Chinook salmon males were stocked into four replicate spawning channels at a constant density (N = 16 per breeding group), but different ratios, and were left to spawn naturallymore » with a fixed number of females (N = 6 per breeding group). Adult males obtained primary access to females and were first to enter the nest at the time of spawning. Jack male spawning occurred primarily by establishing satellite positions downstream of the courting pair, and 'sneaking' into the nest at the time of spawning. Male dominance hierarchies were fairly stable and strongly correlated with the order of nest entry at the time of spawning. Spawning participation by jack and adult males is consistent with a negative frequency dependent selection model, which means that selection during spawning favors the rarer life history form. Results of DNA parentage assignments will be analyzed to estimate adult-to-fry fitness of each male. Objective 2: To determine the critical period(s) for imprinting for sockeye salmon, juvenile salmon were exposed to known odorants at key developmental stages. Molecular assessments of imprinting-induced changes in odorant receptor gene expression indicated that regulation of odorant expression is influenced by developmental status and odor exposure history. The results suggest that sockeye salmon are capable of imprinting to homing cues during the developmental periods that correspond to several of current release strategies employed as part of the Captive Broodstock program (specifically

Pharmacists’ views on involvement in pharmacy practice research: Strategies for facilitating participation

PubMed Central

Armour, Carol; Brillant, Martha; Krass, Ines

In order for community pharmacy practice to continue to evolve, pharmacy practice research on potential new services is essential. This requires the active participation of community pharmacists. At present the level of involvement of community pharmacists in pharmacy practice research is minimal. Objectives To ascertain the attitudes of a group of research-experienced community pharmacists towards participating in research; to investigate the barriers and facilitators to participation; to identify potential strategies to increase the involvement of community pharmacists in research. Methods A focus group was conducted with a purposive sample of 11 research-experienced community pharmacists. A pharmacist academic moderated the focus group using a semi-structured interview guide. The participants were asked about their attitudes towards research, previous involvement in research, barriers to their involvement and strategies to overcome these barriers. The session was audio-taped and notes were taken by an observer. Thematic analysis of the notes and audio-tape transcripts was conducted. Results Three themes emerged around pharmacists’ attitudes towards research: pharmacists’ perception of the purpose of research, pharmacists’ motivation for involvement in research, and pharmacists’ desired role in research. Barriers to research participation were grouped into four themes: pharmacists’ mindset, communication, infrastructure (time, money and staff), and skills/knowledge. Strategies to address each of these barriers were suggested. Conclusions Participants recognised the importance of research towards advancing their profession and this was a motivating factor for involvement in research. They perceived their role in research primarily as data collection. A series of practical strategies to overcome the barriers to participation were offered that researchers may wish to consider when promoting research outcomes and designing research projects.

Broodstock management and hormonal manipulations of fish reproduction.

PubMed

Mylonas, Constantinos C; Fostier, Alexis; Zanuy, Silvia

2010-02-01

Control of reproductive function in captivity is essential for the sustainability of commercial aquaculture production, and in many fishes it can be achieved by manipulating photoperiod, water temperature or spawning substrate. The fish reproductive cycle is separated in the growth (gametogenesis) and maturation phase (oocyte maturation and spermiation), both controlled by the reproductive hormones of the brain, pituitary and gonad. Although the growth phase of reproductive development is concluded in captivity in most fishes-the major exemption being the freshwater eel (Anguilla spp.), oocyte maturation (OM) and ovulation in females, and spermiation in males may require exogenous hormonal therapies. In some fishes, these hormonal manipulations are used only as a management tool to enhance the efficiency of egg production and facilitate hatchery operations, but in others exogenous hormones are the only way to produce fertilized eggs reliably. Hormonal manipulations of reproductive function in cultured fishes have focused on the use of either exogenous luteinizing hormone (LH) preparations that act directly at the level of the gonad, or synthetic agonists of gonadotropin-releasing hormone (GnRHa) that act at the level of the pituitary to induce release of the endogenous LH stores, which, in turn act at the level of the gonad to induce steroidogenesis and the process of OM and spermiation. After hormonal induction of maturation, broodstock should spawn spontaneously in their rearing enclosures, however, the natural breeding behavior followed by spontaneous spawning may be lost in aquaculture conditions. Therefore, for many species it is also necessary to employ artificial gamete collection and fertilization. Finally, a common question in regards to hormonal therapies is their effect on gamete quality, compared to naturally maturing or spawning broodfish. The main factors that may have significant consequences on gamete quality-mainly on eggs-and should be considered

A Tale of Two Temporal Coding Strategies: Common and Dissociable Brain Regions Involved in Recency versus Associative Temporal Order Retrieval Strategies.

PubMed

Lieberman, Jennifer S; Kyle, Colin T; Schedlbauer, Amber; Stokes, Jared; Ekstrom, Arne D

2017-04-01

Numerous studies indicate the importance of the hippocampus to temporal order retrieval. However, behavioral studies suggest that there are different ways to retrieve temporal order information from encoded sequences, one involving an associative strategy (retrieving associations using neighboring items in a list) and another involving a recency strategy (determining which of two items came first). It remains unresolved, however, whether both strategies recruit the hippocampus or only associative strategies, consistent with the hippocampus's role in relational processing. To address this, we developed a paradigm in which we dissociated associative versus recency-based retrieval, involving the same stimulus presentation during retrieval. Associative retrieval involved an increase in RT (and decrease in performance) with greater distances between intervals, consistent with the need to retrieve intervening associations. Recency-based retrieval involved an increase in RT (and decrease in performance) with shorter distances between intervals, suggesting the use of a strength-based coding mechanism to retrieve information. We employed fMRI to determine the neural basis of the different strategies. Both strategies showed significant levels of hippocampal activation and connectivity that did not differ between tasks. In contrast, both univariate and connectivity pattern analyses revealed differences in extrahippocampal areas such as parietal and frontal cortices. A covariate analysis suggested that differences could not be explained by task difficulty alone. Together, these findings suggest that the hippocampus plays a role in both forms of temporal order retrieval, with neocortical networks mediating the different cognitive demands for associative versus recency-based temporal order retrieval.

Dementia-friendly communities: challenges and strategies for achieving stakeholder involvement.

Heward, Michelle; Innes, Anthea; Cutler, Clare; Hambidge, Sarah

2017-05-01

Dementia-friendly communities (DFCs) are a UK policy initiative that aims to enable people with dementia to feel supported and included within their local community. Current approaches to DFC creation rely on stakeholder involvement, often requiring volunteer assistance. There is though a lack of evidence that examines the reality of achieving this. This paper critically assesses the challenges and strategies for achieving stakeholder involvement in DFCs. The evidence base is drawn from an inter-agency project funded by the National Health Service in the South of England where seven DFCs were developed by steering group partners and four part-time project workers (PWs). Data from the independent evaluation undertaken in the first year (2013-2014) of the project were analysed: 14 semi-structured interviews and a focus group examined PWs' experiences; while progress and key milestones are determined from monthly progress forms, good news stories, locality steering group minutes and press releases. Analysis was undertaken using a directed content analysis method, whereby data content for each locality was matched to the analytical framework that was drawn from Alzheimer's Society guidance. Challenges to achieving stakeholder involvement were identified as: establishing networks and including people representative of the local community; involving people affected by dementia; and gaining commitment from organisations. Strategies for achieving stakeholder involvement were recognised as: a sustainable approach; spreading the word; and sharing of ideas. By highlighting these challenges and the approaches that have been used within communities to overcome them, these findings form the foundation for the creation of DFC initiatives that will become embedded within communities. Stakeholder involvement is unpredictable and changeable; therefore, reliance on this approach questions the long-term sustainability of DFCs, and must be considered in future policies designed to

index survey areas in 1995 from as high as 1,205 redds in the same area in 1969 (Table 1). All streams reached low points (0-6 redds in the index areas) in the 1990's, except those in which no redds were found for several years and surveys were discontinued, such as Spring, Sheep and Indian creeks which had a total of 109 redds in 1969. The Minam and Wenaha rivers are tributaries of the Grande Ronde River located primarily in wilderness areas. Chinook salmon numbers in these two streams (based on redd counts) also decreased dramatically beginning in the early 1970's (Table 1). Since then there have been a few years of increasing numbers of redds but counts have generally been 25-40% of the number seen in the 1960's. No hatchery fish have been released into either of these streams and we monitor them during spawning ground surveys for the presence of hatchery strays. These populations will be used as a type of control for evaluating our supplementation efforts in Catherine Creek, upper Grande Ronde River and Lostine River. In this way, we can attempt to filter out the effects of downstream variables, over which we have no control, when we interpret the results of the captive broodstock program as the F1 and F2 generations spawn and complete their life cycles in the wild. The Grande Ronde Basin Captive Broodstock Program was initiated because these chinook salmon populations had reached critical levels where dramatic and unprecedented efforts were needed to prevent extinction and preserve any future options for use of endemic fish for artificial propagation programs for recovery and mitigation. This program was designed to quickly increase numbers of returning adults, while maintaining the genetic integrity of each endemic population.« less

Personifying self in physics problem situations involving forces as a student help strategy

NASA Astrophysics Data System (ADS)

Tabor-Morris, A. E.

2013-03-01

How can physics teachers best guide students regarding physics problem situations involving forces? A suggestion is made here to personify oneself as the object in question, that is, to pretend to be the object undergoing forces and then qualify and quantify those forces according to their vectors for the system at hand. This personification is not meant to empower the object to act, just to sense the forces it is experiencing. This strategy may be especially useful to beginning physics learners attacking problems that involve both multiple forces AND multiple objects, since each object acted upon needs to be considered separately, using the idea that one cannot be two places at once. An example of this type of problem expounded on here is Atwood's machine: two weights hung over a pulley with a single rope. Another example given is electromagnetic forces on one charge caused by other charges in the vicinity. Discussion is made on implementation of classroom strategies. Department of Physics

Although United States employment policies have increased support for people with disabilities working in community settings, the unemployment rate for this population remains very high, particularly for people with intellectual or developmental disabilities. Research shows that job developers (direct support professionals who assist people with disabilities to secure, maintain, and advance in employment) are critical to achieving quality employment outcomes. However, the extent to which job developers use practices that are considered promising in their field (such as engaging families) is not well known. This brief report summarizes findings from a qualitative study about the extent to which job developers use the recommended promising practices when working with individuals and family members. Qualitative analysis identified the following themes among job developers: factors affecting family involvement, perceptions of family involvement, and the influence of expectation on strategies. The field of job development faces a challenge common to many professions: translating research on best practices to those who need this knowledge the most and can use it to greatest effect. Future research should address how community rehabilitation providers (CRPs) communicate about and instill best practices, including effective family engagement, within their organizations. © 2013 John Wiley & Sons Ltd.

2008-11-01

Recruitment and retention of research participants is often the most labor-intensive and difficult component of clinical trials. Poor recruitment and retention frequently pose as a major barrier in the successful completion of clinical trials. In fact, many studies are prematurely terminated, or their findings questioned due to low recruitment and retention rates. The conduct of clinical trials involving youth with a first episode of mental illness comes with additional challenges in recruitment and retention including barriers associated with engagement and family involvement. To develop effective early interventions for first episode mental illness, it is necessary to develop strategies to enhance recruitment and retention in this patient population. This article presents the recruitment and retention challenges experienced in two clinical trials: one involving participants experiencing a first episode of depression and one involving participants experiencing a first episode psychosis. Challenges with recruitment and retention are identified and reviewed at both the patient level and clinician level. Strategies that were implemented to enhance recruitment and retention in these two studies are also discussed. Finally, ethical issues to consider when implementing these strategies are also highlighted.

The Family Health Strategy (FHS) has an acknowledged potential for the promotion of health and the prevention of violence. This is an integrative bibliographic review with the aim of evaluating the performance of FHS professionals in tackling and preventing violence involving adolescents. It is an integrative review of dissertations and theses on healthcare published from 1994 to 2014. The collection of 17 dissertations and 2 doctoral theses reveals that these studies are recent. The FHS professionals acknowledge the vulnerability of adolescents to inflicting and being subject to violence, however the FHS proves ineffective in tackling and preventing such violence. The predominance of the medical technical care model, the deficiencies in Public Health education in professional training and the lack of institutional support are seen as the main obstacles. Many of these professionals are unaware of the files for notification of violence. The existence of family violence and criminal groups were the aspects most mentioned in the territories. The social representation of adolescents as being "problematic" and the lack of ESF actions that promote an increase youth leadership and empowerment were clearly detected.

Motor sequences can be learned using an incremental approach by starting with a few elements and then adding more as training evolves (e.g., learning a piano piece); conversely, one can use a global approach and practice the whole sequence in every training session (e.g., shifting gears in an automobile). Yet, the neural correlates associated with such learning strategies in motor sequence learning remain largely unexplored to date. Here we used functional magnetic resonance imaging to measure the cerebral activity of individuals executing the same 8-element sequence after they completed a 4-days training regimen (2 sessions each day) following either a global or incremental strategy. A network comprised of striatal and fronto-parietal regions was engaged significantly regardless of the learning strategy, whereas the global training regimen led to additional cerebellar and temporal lobe recruitment. Analysis of chunking/grouping of sequence elements revealed a common prefrontal network in both conditions during the chunk initiation phase, whereas execution of chunk cores led to higher mediotemporal activity (involving the hippocampus) after global than incremental training. The novelty of our results relate to the recruitment of mediotemporal regions conditional of the learning strategy. Thus, the present findings may have clinical implications suggesting that the ability of patients with lesions to the medial temporal lobe to learn and consolidate new motor sequences may benefit from using an incremental strategy.

Genetic diversity of wild and hatchery lake trout populations: Relevance for management and restoration in the Great Lakes

Page, K.S.; Scribner, K.T.; Burnham-Curtis, M.

2004-01-01

The biological diversity of lake trout Salvelinus namaycush in the upper Great Lakes was historically high, consisting of many recognizable morphological types and discrete spawning populations. During the 1950s and 1960s, lake trout populations were extirpated from much of the Great Lakes primarily as a result of overfishing and predation by the parasitic sea lamprey Petromyzon marinus. Investigations of how genetic diversity is partitioned among remnant wild lake trout populations and hatchery broodstocks have been advocated to guide lake trout management and conservation planning. Using microsatellite genetic markers, we estimated measures of genetic diversity and the apportionment of genetic variance among 6 hatchery broodstocks and 10 wild populations representing three morphotypes (lean, humper, and siscowet). Analyses revealed that different hatchery broodstocks and wild populations contributed disproportionally to the total levels of genetic diversity. The genetic affinities of hatchery lake trout reflected the lake basins of origin of the wild source populations. The variance in allele frequency over all sampled extant wild populations was apportioned primarily on the basis of morphotype (??MT = 0.029) and secondarily among geographically dispersed populations within each morphotype (??ST = 0.024). The findings suggest that the genetic divergence reflected in recognized morphotypes and the associated ecological and physiological specialization occurred prior to the partitioning of large proglacial lakes into the Great Lakes or as a consequence of higher contemporary levels of gene flow within than among morphotypes. Information on the relative contributions of different broodstocks to total gene diversity within the regional hatchery program can be used to prioritize the broodstocks to be retained and to guide future stocking strategies. The findings highlight the importance of ecological and phenotypic diversity in Great Lakes fish communities and

Parental Involvement in Middle School: A Meta-Analytic Assessment of the Strategies That Promote Achievement

Early adolescence is often marked by changes in school context, family relationships, and developmental processes. In the context of these changes, academic performance often declines, while at the same time the long-term implications of academic performance increase. In promoting achievement across elementary and secondary school levels, the significant role of families, family-school relations, and parental involvement in education has been highlighted. Although there is a growing body of literature focusing on parental involvement in education during middle school, this research has not been systematically examined to determine which types of involvement have the strongest relation with achievement. The authors conducted a meta-analysis on the existing research on parental involvement in middle school to determine whether and which types of parental involvement are related to achievement. Across 50 studies, parental involvement was positively associated with achievement, with the exception of parental help with homework. Involvement that reflected academic socialization had the strongest positive association with achievement. Based on the known characteristics of the developmental stage and tasks of adolescence, strategies reflecting academic socialization are most consistent with the developmental stage of early adolescence.

The ability to recruit qualified subjects who are willing to adhere to the study protocol in clinical trials is an essential component of translational research. Such tasks can be particularly challenging for chemoprevention studies when the targeted study population is healthy, at risk individuals who do not have signs or symptoms of the disease, and the study participation involves complex scheduling and invasive procedures such as bronchoscopy. In this report, we describe the recruitment process and evaluated the effectiveness of various recruitment strategies utilized in our National Cancer Institute sponsored lung cancer chemoprevention study with celecoxib. Heavy ex-smokers were recruited into the study through various methods such as radio advertisements, print media, mass mailings, flyers, internet postings and others. The number of inquiries, on-site screenees and randomization generated by each method determined the efficacy of that recruitment strategy. We prescreened 4470 individuals, invited 323 people for on-site screening and randomized 137 subjects. Radio advertisements (ads) generated the most inquiries (71.1%), followed by internet posting (11.8%), print media (6.0%), posted and racked flyers (4.4%), mass mailings (2.7%) and other strategies such as referrals from friends or family members or health care providers (2.3%). Radio ads, although costly, yielded the most subjects for on-site screening and randomization. Moreover, among the various types of radio stations, news radio stations were by far the most successful. Our results suggest that advertising on news radio is a highly effective recruitment method for successful accrual of ex-smokers into lung cancer chemoprevention trials.

Previous research looking at published systematic reviews has shown that their search strategies are often suboptimal and that librarian involvement, though recommended, is low. Confidence in the results, however, is limited due to poor reporting of search strategies the published articles. To more accurately measure the use of recommended search methods in systematic reviews, the levels of librarian involvement, and whether librarian involvement predicts the use of recommended methods. A survey was sent to all authors of English-language systematic reviews indexed in the Database of Abstracts of Reviews of Effects (DARE) from January 2012 through January 2014. The survey asked about their use of search methods recommended by the Institute of Medicine, Cochrane Collaboration, and the Agency for Healthcare Research and Quality and if and how a librarian was involved in the systematic review. Rates of use of recommended methods and librarian involvement were summarized. The impact of librarian involvement on use of recommended methods was examined using a multivariate logistic regression. 1560 authors completed the survey. Use of recommended search methods ranged widely from 98% for use of keywords to 9% for registration in PROSPERO and were generally higher than in previous studies. 51% of studies involved a librarian, but only 64% acknowledge their assistance. Librarian involvement was significantly associated with the use of 65% of recommended search methods after controlling for other potential predictors. Odds ratios ranged from 1.36 (95% CI 1.06 to 1.75) for including multiple languages to 3.07 (95% CI 2.06 to 4.58) for using controlled vocabulary. Use of recommended search strategies is higher than previously reported, but many methods are still under-utilized.

2013-12-01

Early engagement in research can transform the undergraduate experience and has a positive effect on minority student recruitment to graduate school. Multiple strategies used to involve undergraduates in research at a large R1 university are presented. During my first four years as an assistant professor, my lab has hosted 14 undergraduates, 9 of them women and 4 of them Hispanic. Institutional support has been critical for undergraduate student involvement. UW supports a research program for incoming underrepresented students. An advantage of this program is very early research participation, with the opportunity for long-term training. One disadvantage is that many first year students have not yet identified their interests. The Biology major also requires students to complete an independent project, which culminates in a research symposium. Competitive research fellowships and grants are available for students to conduct work under faculty mentorship. We have been successful at keeping students on even when their majors are very different from our research discipline, mainly by providing flexibility and a welcoming lab environment. This mentoring culture is strongly fostered by graduate student interest and involvement with all undergraduates as well as active mentor training. By offering multiple pathways for involvement, we can accommodate students' changing schedules and priorities as well as changing lab needs. Students can volunteer, receive course credit, conduct an independent project or honors thesis, contribute to an existing project, do lab work or write a literature review, work with one mentor or on multiple projects. We often provide employment over the summer and subsequent semesters for continuing students. Some will increase their commitment over time and work more closely with me. Others reduce down to a few hours a week as they gain experience elsewhere. Most students stay multiple semesters and multiple years because they 'enjoy being in the

As engaging men in gender-based violence prevention efforts becomes an increasingly institutionalised component of gender equity work globally, clarity is needed about the strategies that best initiate male-identified individuals' involvement in these efforts. The purpose of this study was to examine the perceived relevance and effectiveness of men's engagement strategies from the perspective of men around the world who have organised or attended gender-based violence prevention events. Participants responded to an online survey (available in English, French and Spanish) and rated the effectiveness of 15 discrete engagement strategies derived from earlier qualitative work. Participants also provided suggestions regarding strategies in open-ended comments. Listed strategies cut across the social ecological spectrum and represented both venues in which to reach men, and the content of violence prevention messaging. Results suggest that all strategies, on average, were perceived as effective across regions of the world, with strategies that tailor messaging to topics of particular concern to men (such as fatherhood and healthy relationships) rated most highly. Open-ended comments also surfaced tensions, particularly related to the role of a gender analysis in initial men's engagement efforts. Findings suggest the promise of cross-regional adaptation and information sharing regarding successful approaches to initiating men's anti-violence involvement.

Advocacy coalitions often play an important role in the state health policymaking process, yet little is known about their structure, composition, and behavior. In 2008, California became the first state to enact a menu labeling law. Using the advocacy coalition framework, we examine different facets of the coalitions involved in California's menu labeling policy debate. We use a qualitative research approach to identify coalition members and explore their expressed beliefs and policy arguments, resources, and strategies by analyzing legislative documents (n = 87) and newspaper articles (n = 78) produced between 1999 and 2009. Between 2003 and 2008, six menu labeling bills were introduced in the state's legislature. We found the issue received increasing media attention during this period. We identified two advocacy coalitions involved in the debate-a public health (PH) coalition and an industry coalition. State organizations acted as coalition leaders and participated for a longer duration than elected officials. The structure and composition of each coalition varied. PH coalition leadership and membership notably increased compared to the industry coalition. The PH coalition, led by nonprofit PH and health organizations, promoted a clear and consistent message around informed decision making. The industry coalition, led by a state restaurant association, responded with cost and implementation arguments. Each coalition used various resources and strategies to advance desired outcomes. PH coalition leaders were particularly effective at using resources and employing advocacy strategies, which included engaging state legislators as coalition members, using public opinion polls and information, and leveraging media resources to garner support. Policy precedence and a local policy push emerged as important policymaking strategies. Areas for future research on the state health policymaking process are discussed.

To report the findings from an evaluation of the impact of the Compassion in Practice Vision and Strategy (National Health Service England (NHSE), 2012) on nursing, midwifery and care staff. The Compassion in Practice Vision and Strategy was a programme of work to highlight the importance of compassionate care following the Francis Report in 2013 into the deficits in care in an NHS Hospital Trust. It was launched by NHS England in 2012 at a time when fiscal cuts were introduced by the Department of Health in England. Mixed methods. Inferential statistics were used to test whether there were significant differences between staff at different levels of seniority with regard to awareness and involvement in Compassion in Practice Vision and Strategy and their attitudes to it. Awareness and involvement of staff in Compassion in Practice Vision and Strategy were high amongst middle and senior management but limited at ward level. Staff involvement in Compassion in Practice Vision and Strategy was limited due to a lack of awareness. Ward level staff who were aware and involved, perceived a lack of support and communication from senior leadership to deliver the Compassion in Practice Vision and Strategy. Results reveal professional anger, distress and resistance to the Compassion in Practice Vision and Strategy and a view of the programme as a top-down initiative which did not sufficiently recognise structural constraints on nurses' ability to deliver compassionate care. We discuss the implications of our findings for global nursing. Participants emphasised that compassion for patients is only sustainable where there is compassion for staff and many participants felt that they were not being treated with compassion. National Health Service England should strongly affirm that nurses and midwives in general provide compassionate care. Trust leadership should provide support for ward level staff who deliver compassionate care in difficult circumstances. © 2017 John Wiley

Understanding the effectiveness of the entertainment-education strategy: an investigation of how audience involvement, message processing, and message design influence health information recall.

PubMed

Quintero Johnson, Jessie M; Harrison, Kristen; Quick, Brian L

2013-01-01

A growing body of evidence suggests that entertainment-education (EE) is a promising health communication strategy. The purpose of this study was to identify some of the factors that facilitate and hinder audience involvement with EE messages. Using confirmatory factor analysis, the authors introduce a construct they call experiential involvement, which describes the experience of being cognitively and emotionally involved with EE messages and is a product of transportation into an EE text and identification with EE characters. Using an experimental design, the authors also investigated how reports of experiential involvement and health information recall varied depending on the degree to which the educational content was well integrated with the narrative content in EE messages. Findings indicated that integration significantly influenced health information recall. Results indicated that experiential involvement and the perception that the health topic in EE messages was personally relevant predicted participants' systematic processing of the information in EE messages. Contrary to expectation, personal relevance did not predict experiential involvement, and systematic message processing was negatively related to health information recall. Implications for the construction of EE messages and the study of the EE strategy are discussed.

2013-12-16

Despite the documented benefits of prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) services, the uptake remains low in sub-Saharan Africa. The lack of male involvement (MI) may be one of the reasons for this. However, there are limited data on strategies for MI in PMTCT. The objective of this study was to identify strategies that may promote MI in PMTCT services in antenatal care (ANC) services in Blantyre, Malawi. An exploratory qualitative study was conducted from December 2012 to January 2013 at South Lunzu Health Centre (SLHC) in Blantyre, Malawi. It consisted of six face-to-face key informant interviews (KIIs) with healthcare workers and four focus group discussions (FGDs) with 18 men and 17 pregnant women attending ANC at SLHC. The FGDs were divided according to sex and age. All FGDs and KIIs were digitally recorded and simultaneously transcribed and translated verbatim into English. Data were analyzed using thematic content analysis. Three major themes with several subcategories emerged. Theme 1 was a gatekeeping strategy with two subcategories: (1) healthcare workers refusing service provision to women accessing antenatal clinic without their partners and (2) women refusing ANC attention in the absence of a partner. Theme 2 comprised extending invitations and had six subcategories: (1) word of mouth, (2) card invites, (3) woman's health passport book invites, (4) telephonic invites, (5) use of influential people, and (6) home visits. Theme 3 was information education and communication, such as health education forums and advertisements. Of all the strategies, an invitation card addressed to the male partner was most preferred by study participants. There are several strategies by which men may be involved in PMTCT. Healthcare workers should offer a pregnant woman all strategies available for MI for her to select the appropriate one. Further research and consultations with men should continue to achieve higher levels

[End-of-Life Care in Intensive Care Units: Nursing strategies of family involvement at the end of life].

PubMed

Cyrol, Katharina; Fröhlich, Martin R; Piatti, Francesca; Imhof, Lorenz

2018-06-01

Background: Family members of people dying in the intensive care unit (ICU) are exposed to many stress factors and they often do not experience involvement in End-of-Life (EoL) situations. For example, they criticize a low degree of participation in patients care, delayed or incomplete information and lack of privacy. Even nursing staff is facing various obstacles in EoL situations in ICUs. Aim: This study investigates strategies used by ICU nursing staff in German-speaking Switzerland to increase family members participation in situations at the end of life. Method: Data was collected by conducting 12 semi-structured interviews using an approach based on Grounded Theory. A model was developed to explain nursing strategies for family involvement in EoL situations in the ICU. Conclusions: Nurses provide personal space and tranquillity for family members and allow them to be present at any time. Against this background, they support family members and enable them to say goodbye consciously to a loved one. Subsequent work should examine the effectiveness of the strategies described, particularly in terms of stress reactions displayed by family members in the aftermath of EoL situations. In practice, family members should be provided space for privacy. The entire healthcare team is recommended to identify and pursue common values and objectives. Moreover, intradisciplinary exchange and mentoring need to be encouraged. In order to prepare future nursing staff for EoL situations in the ICU, recognizing and promoting their educational skills is mandatory.

Natural Reproductive Success and Demographic Effects of Hatchery-Origin Steelhead in Abernathy Creek, Washington : Annual Report 2008.

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

U.S. Fish & Wildlife Service, Abernathy Fish Technology Center

2008-12-01

Many hatchery programs for steelhead pose genetic or ecological risks to natural populations because those programs release or outplant fish from non-native stocks. The goal of many steelhead programs has been to simply provide 'fishing opportunities' with little consideration given to conservation concerns. For example, the Washington Department of Fish and Wildlife (WDFW) has widely propagated and outplanted one stock of winter-run steelhead (Chambers Creek stock) and one stock of summer-run steelhead (Skamania stock) throughout western Washington. Biologists and managers now recognize potential negative effects can occur when non-native hatchery fish interact biologically with native populations. Not only do non-nativemore » stocks pose genetic and ecological risks to naturally spawning populations, but non-native fish stray as returning adults at a much higher rate than do native fish (Quinn 1993). Biologists and managers also recognize the need to (a) maintain the genetic resources associated with naturally spawning populations and (b) restore or recover natural populations wherever possible. As a consequence, the U.S. Fish & Wildlife Service (USFWS) and the NOAA Fisheries have been recommending a general policy that discourages the use of non-native hatchery stocks and encourages development of native broodstocks. There are two primary motivations for these recommendations: (1) reduce or minimize potential negative biological effects resulting from genetic or ecological interactions between hatchery-origin and native-origin fish and (2) use native broodstocks as genetic repositories to potentially assist with recovery of naturally spawning populations. A major motivation for the captive-rearing work described in this report resulted from NOAA's 1998 Biological Opinion on Artificial Propagation in the Columbia River Basin. In that biological opinion (BO), NOAA concluded that non-native hatchery stocks of steelhead jeopardize the continued existence of U

Arm coordination in octopus crawling involves unique motor control strategies.

PubMed

Levy, Guy; Flash, Tamar; Hochner, Binyamin

2015-05-04

To cope with the exceptional computational complexity that is involved in the control of its hyper-redundant arms [1], the octopus has adopted unique motor control strategies in which the central brain activates rather autonomous motor programs in the elaborated peripheral nervous system of the arms [2, 3]. How octopuses coordinate their eight long and flexible arms in locomotion is still unknown. Here, we present the first detailed kinematic analysis of octopus arm coordination in crawling. The results are surprising in several respects: (1) despite its bilaterally symmetrical body, the octopus can crawl in any direction relative to its body orientation; (2) body and crawling orientation are monotonically and independently controlled; and (3) contrasting known animal locomotion, octopus crawling lacks any apparent rhythmical patterns in limb coordination, suggesting a unique non-rhythmical output of the octopus central controller. We show that this uncommon maneuverability is derived from the radial symmetry of the arms around the body and the simple pushing-by-elongation mechanism by which the arms create the crawling thrust. These two together enable a mechanism whereby the central controller chooses in a moment-to-moment fashion which arms to recruit for pushing the body in an instantaneous direction. Our findings suggest that the soft molluscan body has affected in an embodied way [4, 5] the emergence of the adaptive motor behavior of the octopus. Copyright © 2015 Elsevier Ltd.

We conducted single point-in-time and repeated cross-sectional studies of the prevalence of antibodies against nervous necrosis virus (NNV) in populations of adult barramundi Lates calcarifer in Australia. Serum samples collected between 2002 and 2012 were analyzed with indirect ELISA (n = 468). Most of the samples were sourced from broodstock with unknown exposure history, and these were compared with reference populations with confirmed history of exposure to NNV. Non-lethally collected gonad fluid samples from economically valuable barramundi broodstock (n = 164) were tested for the presence of NNV using RT-quantitative PCR at the time of blood sampling to compare infectivity with serostatus, but no virus was detected. NNV-specific immunoreactivity in broodstock was significantly lower than that for immunized and persistently infected populations. Seroprevalence increased over time in broodstock sampled longitudinally, probably reflecting repeated exposure to NNV in a region where the virus was endemic. The seroprevalence for the broodstock was 23.8% over the entire sample period while a cross-sectional survey conducted in 2012 found a seroprevalence of 34.5% with no significant difference between populations based on the geographic region or the history of occurrence of viral nervous necrosis (VNN) disease in the progeny in the respective hatcheries. Although serological surveillance was useful for studying the history of exposure of barramundi to NNV, the lack of association between serostatus in broodstock and the subsequent occurrence of VNN disease in their progeny indicates that ELISA tests for anti-NNV antibodies are not suitable for the purpose of preventing vertical transmission of NNV in barramundi.

Three stellar occultation opportunities were identified in 2017 involving the New Horizons extended mission target: (486958) 2014 MU69. The first event was on 2017 June 3 and predicted to be visible from southern South America and southern Africa with a somewhat faint star with g’=15.33. The second event was on 2017 June 10 under very difficult observing conditions just 16° from a full moon and the faintest star of the three with g’=15.57. The third event was on 2017 July 17 and predicted to be visible from southern Argentina with the brightest star of the three with g’=12.60. We pursued each of these events with an observing plan and strategy tuned to the constraints imposed by observing conditions and the anticipated prediction uncertainties. The first and third events were amenable to a ground-based telescope deployment and we fielded 25 telescopes. The second event was possible only with SOFIA (Stratospheric Observatory For Infrared Astronomy). The deployment for the first event involved splitting resources between two continents and a strategy optimized to prevent a null result for a D=40km object. The second event was optimized for the search for dust and rings but had a 75% chance of a solid body event for a D=40 km size. The third event was driven by needing to prevent a null result on a D=10 km size and providing extra conservatism on the ground-track uncertainty while observing from the area of Comodoro Rivadavia, Argentina. All campaigns were successful in recording data essential for the constraint on dust or rings around MU69: June 3, 24 lightcurves; July 10, 1 lightcurve; July 17, 23 lightcurves. Only the last event was able to record solid-body chords from the object with 5 chords detected close to the predicted time and place. We will present an overview of the strategies and basic results of the campaigns. This work would not have been possible without the financial support of the New Horizons mission and NASA, astrometric support of the

[International trade in living penaeid shrimp between countries in the Pacific and the Atlantic areas and in Europe].

PubMed

Michel, A

1996-06-01

The tremendous development of penaeid shrimp culture across the world over the past twenty years has led to international trade in eggs, larvae and spawners of the best shrimp species for aquaculture. Trade has involved, in particular, the following species: -Penaeus japonicus from Japan to Europe, the Pacific Islands and South America -P. monodon from South-East Asia to almost all tropical countries -P. vannamei and P. stylirostris from countries along the Pacific coast of South and central America to the United States of America, the islands of the South Pacific, countries along the Atlantic coast of the Americas and certain countries in Africa. In the 1980s, research conducted by American and French teams enabled the breeding of stocks of spawners in captivity. This resulted in the establishment of lines of captive broodstock outside natural areas of distribution, and the development of new breeding farms in previously unproductive regions. Trade related to movements of these species is facilitated by the absence of legislation in most countries; even when such legislation does exist, it is not always applied. These practices have led to the rapid development of world shrimp production, but have also contributed to the dissemination of pathogens. In recent years, the occurrence of serious epizootics - occasioning heavy losses world-wide - has led to a more cautious approach involving trade of post-larvae obtained from captive broodstock in which thorough control measures have been implemented for known diseases. Trade in wild shrimp will probably be abandoned progressively, to avoid the risk of introducing new pathogens. The main challenges for research in the near future are the development of diagnostic tools, to enable continuous control of captive broodstock, and the selection of strains which are resistant to the principal pathogens affecting these species.

Middle manager involvement in strategy development in not-for profit organizations: the director of nursing perspective--how organizational structure impacts on the role.

PubMed

Carney, M

2004-01-01

An attempt was made to link organizational structure and strategic management and, in the process, to identify how organizational structure impacts on the strategic management role of Directors of Nursing working in acute care hospitals in the Republic of Ireland. Directors of Nursing are recognized as holding a pivotal role in health care delivery. The need for their involvement in strategic management is acknowledged, yet it is not clear if this role is influenced by organizational structure. It is recognized that strategic involvement increases the likelihood that middle managers' initiatives will be in line with top management's concept of corporate strategy. The principal thesis is that organizational members will exercise a higher level of strategic consensus if they have been initially involved in the development of strategy. The study was undertaken in not-for-profit health service organizations, through a series of 25 semi-structured interviews with Directors of Nursing. The review of the literature was undertaken simultaneously with grounded theory analysis of the interviews. This research suggests that structure does impact on the role, conferring both positive benefits and negative consequences. Structure is identified in this study, in terms of organizational hierarchy, and the locus of control pertaining in each organization. Two predominating structure models are discussed and analysed.

"Research to Improve the Efficacy of Captive Broodstock Programs and Advance Hatchery Reform Throughout the Columbia River Basin." [from the Abstract], 2008-2009 Progress Report.

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

Berejikian, Barry A.

This project was developed to conduct research to improve the efficacy of captive broodstock programs and advance hatchery reform throughout the Columbia River Basin. The project has three objectives: (1) maintain adaptive life history characteristics in Chinook salmon, (2) improve imprinting in juvenile sockeye salmon, and (3) match wild phenotypes in Chinook and sockeye salmon reared in hatcheries. A summary of the results are as follows: Objective 1: The ratio of jack to adult male Chinook salmon were varied in experimental breeding populations to test the hypothesis that reproductive success of the two male phenotypes would vary with their relativemore » frequency in the population. Adult Chinook salmon males nearly always obtained primary access to nesting females and were first to enter the nest at the time of spawning. Jack male spawning occurred primarily by establishing satellite positions downstream of the courting pair, and 'sneaking' into the nest at the time of spawning. Male dominance hierarchies were fairly stable and strongly correlated with the order of nest entry at the time of spawning. Observed participation in spawning events and adult-to-fry reproductive success of jack and adult males was consistent with a negative frequency-dependent selection model. Overall, jack males sired an average of 21% of the offspring produced across a range of jack male frequencies. Implications of these and additional findings on Chinook salmon hatchery broodstock management will be presented in the FY 2009 Annual Report. Objective 2: To determine the critical period(s) for imprinting for sockeye salmon, juvenile salmon were exposed to known odorants at key developmental stages. Molecular assessments of imprinting-induced changes in odorant receptor gene expression indicated that regulation of odorant expression is influenced by developmental status and odor exposure history.

Roles of insulin-like growth factors in metamorphic development of turbot (Scophthalmus maximus).

PubMed

Jia, Yudong

2018-01-31

Larval turbot (Scophthalmus maximus) undergo metamorphosis, a late post-embryonic developmental event that precedes juvenile transition. Insulin-like growth factors (IGFs) are important endocrine/autocrine/paracrine factors that provide essential signals to control of the embryonic and postnatal development of vertebrate species, including fish. Accumulating evidence suggests that IGFs are involved in regulating the metamorphic development of flatfish. This mini review focus on the functions of all known IGFs (IGF-I and IGF-II) during the metamorphic development of turbot. Information about IGFs and insulin-like growth factors binding proteins (IGFBPs) from other teleosts is also included in this review to provide an overview of IGFs functions in the metamorphic development of turbot. These findings may enhance our understanding of the potential roles of the IGFs system in controlling of flatfish metamorphosis and contributing to the improvement of broodstock management strategies for larval turbot.

The current healthcare systems are built around the traditional paradigm of patients suffering from a single acute illness. They are, therefore, largely unprepared to face the increasing demands for health services arising from the expansion of an older population with specific medical needs related to multiple chronic disorders. As a consequence, the medical conditions of a large and growing segment of the older European population are not efficiently managed by the available healthcare services. In the context of an aging population, policy makers such as the European Commission and European Institutions, such as the European Medicines Agency (EMA), devote time and resources to study and accompany the need of the aging population. The EMA recognizes the importance of making sure that the needs of the Elderly are considered during development, approval, and use of new medicines, and, therefore, engages with healthcare professional organisations.

Several factors are associated with an increased risk of adolescent problem gambling, including positive gambling attitudes, higher levels of gambling involvement, ineffective coping strategies and unhelpful parenting practices. It is less clear, however, how these factors interact or influence each other in the development of problem gambling behavior during adolescence. The aim of the current study was to simultaneously explore these predictors, with a particular focus on the extent to which coping skills and parenting styles may moderate the expected association between gambling involvement and gambling problems. Participants were 612 high school students. The data were analyzed using a zero-inflated Poisson (ZIP) regression model, controlling for gender. Although several variables predicted the number of symptoms associated with problem gambling, none of them predicted the probability of displaying any problem gambling. Gambling involvement fully mediated the relationship between positive gambling attitudes and gambling problem severity. There was a significant relationship between gambling involvement and problems at any level of problem focused coping, reference to others and inconsistent discipline. However, adaptive coping styles employed by adolescents and consistent disciplinary practices by parents were buffers of gambling problems at low levels of adolescent gambling involvement, but failed to protect adolescents when their gambling involvement was high. These findings indicate that research exploring the development of gambling problems is required and imply that coping and parenting interventions may have particular utility for adolescents who are at risk of development gambling problems but who are not gambling frequently.

Involving children in cooking has been suggested as a strategy to improve dietary habits in childhood. Interventions in schools including cooking, gardening and tasting activities have showed promising results. Several cross-sectional surveys demonstrated associations between frequency of involvement in food preparation and better diet quality. However, experimental studies confirming the beneficial effect of cooking on food choices in children are missing from the literature. The objective of the present study was to assess the effect of involving children in cooking on their willingness to taste novel foods, food intake, liking and hunger. A between-subject experiment was conducted with 137 children between 7 and 11 years old. 69 children (COOK group) participated in the preparation of three unfamiliar foods containing vegetables: apple/beetroot juice, zucchini tortilla sandwich and spinach cookies. 68 children (CONTROL group) participated, instead, in a creative workshop. Afterwards, the children were invited to choose, for an afternoon snack, between three familiar vs. unfamiliar foods: orange vs. apple/beetroot juice, potato vs. zucchini tortilla sandwich and chocolate vs. spinach cookie. The mean number of unfamiliar foods chosen per child was higher in the COOK vs. CONTROL group (P = 0.037). The overall willingness to taste the unfamiliar foods was also higher in the COOK group (P = 0.011). The liking for the whole afternoon snack (P = 0.034), for 2 of 3 unfamiliar foods and for 1 of 3 familiar foods was higher in the COOK group (P < 0.05). We did not demonstrate any difference between the two groups in overall food intake and hunger/satiety scores. This study demonstrated that involving children in cooking can increase their willingness to taste novel foods and direct food choices towards foods containing vegetables.

User involvement in the implementation of clinical guidelines for common mental health disorders: a review and compilation of strategies and resources.

PubMed

Moreno, Eliana M; Moriana, Juan Antonio

2016-08-09

There is now broad consensus regarding the importance of involving users in the process of implementing guidelines. Few studies, however, have addressed this issue, let alone the implementation of guidelines for common mental health disorders. The aim of this study is to compile and describe implementation strategies and resources related to common clinical mental health disorders targeted at service users. The literature was reviewed and resources for the implementation of clinical guidelines were compiled using the PRISMA model. A mixed qualitative and quantitative analysis was performed based on a series of categories developed ad hoc. A total of 263 items were included in the preliminary analysis and 64 implementation resources aimed at users were analysed in depth. A wide variety of types, sources and formats were identified, including guides (40%), websites (29%), videos and leaflets, as well as instruments for the implementation of strategies regarding information and education (64%), self-care, or users' assessment of service quality. The results reveal the need to establish clear criteria for assessing the quality of implementation materials in general and standardising systems to classify user-targeted strategies. The compilation and description of key elements of strategies and resources for users can be of interest in designing materials and specific actions for this target audience, as well as improving the implementation of clinical guidelines.

Antisense targeting of 3' end elements involved in DUX4 mRNA processing is an efficient therapeutic strategy for facioscapulohumeral dystrophy: a new gene-silencing approach.

2016-04-15

Defects in mRNA 3'end formation have been described to alter transcription termination, transport of the mRNA from the nucleus to the cytoplasm, stability of the mRNA and translation efficiency. Therefore, inhibition of polyadenylation may lead to gene silencing. Here, we choose facioscapulohumeral dystrophy (FSHD) as a model to determine whether or not targeting key 3' end elements involved in mRNA processing using antisense oligonucleotide drugs can be used as a strategy for gene silencing within a potentially therapeutic context. FSHD is a gain-of-function disease characterized by the aberrant expression of the Double homeobox 4 (DUX4) transcription factor leading to altered pathogenic deregulation of multiple genes in muscles. Here, we demonstrate that targeting either the mRNA polyadenylation signal and/or cleavage site is an efficient strategy to down-regulate DUX4 expression and to decrease the abnormally high-pathological expression of genes downstream of DUX4. We conclude that targeting key functional 3' end elements involved in pre-mRNA to mRNA maturation with antisense drugs can lead to efficient gene silencing and is thus a potentially effective therapeutic strategy for at least FSHD. Moreover, polyadenylation is a crucial step in the maturation of almost all eukaryotic mRNAs, and thus all mRNAs are virtually eligible for this antisense-mediated knockdown strategy. © The Author 2016.

Mayo, Sara; Cominelli, Eleonora; Sparvoli, Francesca; González-López, Oscar; Rodríguez-González, Alvaro; Gutiérrez, Santiago; Casquero, Pedro A

2016-01-01

Bean production is affected by a wide diversity of fungal pathogens, among them Rhizoctonia solani is one of the most important. A strategy to control bean infectious diseases, mainly those caused by fungi, is based on the use of biocontrol agents (BCAs) that can reduce the negative effects of plant pathogens and also can promote positive responses in the plant. Trichoderma is a fungal genus that is able to induce the expression of genes involved in plant defense response and also to promote plant growth, root development and nutrient uptake. In this article, a strategy that combines in silico analysis and real time PCR to detect additional bean defense-related genes, regulated by the presence of Trichoderma velutinum and/or R. solani has been applied. Based in this strategy, from the 48 bean genes initially analyzed, 14 were selected, and only WRKY33, CH5b and hGS showed an up-regulatory response in the presence of T. velutinum. The other genes were or not affected (OSM34) or down-regulated by the presence of this fungus. R. solani infection resulted in a down-regulation of most of the genes analyzed, except PR1, OSM34 and CNGC2 that were not affected, and the presence of both, T. velutinum and R. solani, up-regulates hGS and down-regulates all the other genes analyzed, except CH5b which was not significantly affected. As conclusion, the strategy described in the present work has been shown to be effective to detect genes involved in plant defense, which respond to the presence of a BCA or to a pathogen and also to the presence of both. The selected genes show significant homology with previously described plant defense genes and they are expressed in bean leaves of plants treated with T. velutinum and/or infected with R. solani.

2011-01-01

The current study uses a sensemaking model and thinking strategies identified in earlier research to examine ethical decision-making. Using a sample of 163 undergraduates, a low fidelity simulation approach is used to study the effects personal involvement (in causing the problem and personal involvement in experiencing the outcomes of the problem) could have on the use of cognitive reasoning strategies that have been shown to promote ethical decision-making. A mediated model is presented which suggests that environmental factors influence reasoning strategies, reasoning strategies influence sensemaking, and sensemaking in turn influences ethical decision-making. Findings were mixed but generally supported the hypothesized model. Interestingly, framing the outcomes of ethically charged situations in terms of more global organizational outcomes rather than personal outcomes was found to promote the use of pro-ethical cognitive reasoning strategies.

Monitoring and Evaluation of Supplemented Spring Chinook Salmon and Life Histories of Wild Summer Steelhead in the Grande Ronde Basin, 2007 Annual Report.

This is the ninth annual report for a multi-year project designed to monitor and evaluate supplementation of endemic spring Chinook salmon in Catherine Creek and the upper Grande Ronde River. These two streams historically supported anadromous fish populations that provided significant tribal and non-tribal fisheries, but in recent years, have experienced severe declines in abundance. Conventional and captive broodstock supplementation methods are being used to restore these spring Chinook salmon populations. Spring Chinook salmon populations in Catherine Creek and the upper Grande Ronde River, and other streams in the Snake River Basin have experienced severe declines in abundance over themore » past two decades (Nehlsen et al. 1991). A supplementation program was initiated in Catherine Creek and the upper Grande Ronde River, incorporating the use of both captive and conventional broodstock methods, in order to prevent extinction in the short term and eventually rebuild populations. The captive broodstock component of the program (BPA Project 199801001) uses natural-origin parr collected by seining and reared to maturity at facilities near Seattle, Washington (Manchester Marine Laboratory) and Hood River, Oregon (Bonneville Hatchery). Spawning occurs at Bonneville Hatchery, and resulting progeny are reared in hatcheries. Shortly before outmigration in the spring, juveniles are transferred to acclimation facilities. After an acclimation period of about 2-4 weeks, volitional release begins. Any juveniles remaining after the volitional release period are forced out. The conventional broodstock component uses returning adults collected at traps near the spawning areas, transported to Lookingglass Hatchery near Elgin, Oregon, held, and later spawned. The resulting progeny are reared, acclimated, and released similar to the captive broodstock component. All progeny released receive one or more marks including a fin (adipose) clip, codedwire tag, PIT tag, or visual

Efforts over several decades to restore lake trout Salvelinus namaycush in U.S. waters of the upper Great Lakes have emphasized the stocking of juveniles from each of six hatchery broodstocks. Retention of genetic diversity across all offspring life history stages throughout the hatchery system has been an important component of the restoration hatchery and stocking program. Different stages of the lake trout hatchery program were examined to determine how effective hatchery practices have been in minimizing the loss of genetic diversity in broodstock adults and in progeny stocked. Microsatellite loci were used to estimate allele frequencies, measures of genetic diversity, and relatedness for wild source populations, hatchery broodstocks, and juveniles. We also estimated the effective number of breeders for each broodstock. Hatchery records were used to track destinations of fertilized eggs from all spawning dates to determine whether adult contributions to stocking programs were proportional to reproductive effort. Overall, management goals of maintaining genetic diversity were met across all stages of the hatchery program; however, we identified key areas where changes in mating regimes and in the distribution of fertilized gametes and juveniles could be improved. Estimates of effective breeding population size (Nb) were 9-41% of the total number of adults spawned. Low estimates of Nb were primarily attributed to spawning practices, including the pooling of gametes from multiple males and females and the reuse of males. Nonrandom selection and distribution of fertilized eggs before stocking accentuated declines in effective breeding population size and increased levels of relatedness of juveniles distributed to different rearing facilities and stocking locales. Adoption of guidelines that decrease adult reproductive variance and promote more equitable reproductive contributions of broodstock adults to juveniles would further enhance management goals of

2013-01-01

The correlations between protein glycosylation and many biological processes and diseases are increasing the demand for quantitative glycomics strategies enabling sensitive monitoring of changes in the abundance and structure of glycans. This is currently attained through multiple strategies employing several analytical techniques such as capillary electrophoresis, liquid chromatography, and mass spectrometry. The detection and quantification of glycans often involve labeling with ionic and/or hydrophobic reagents. This step is needed in order to enhance detection in spectroscopic and mass spectrometric measurements. Recently, labeling with stable isotopic reagents has also been presented as a very viable strategy enabling relative quantitation. The different strategies available for reliable and sensitive quantitative glycomics are herein described and discussed. PMID:23325767

Human cytosolic glutathione-S-transferases: quantitative analysis of expression, comparative analysis of structures and inhibition strategies of isozymes involved in drug resistance.

PubMed

2017-08-01

Glutathione-S-transferase (GST) inhibition is a strategy to overcome drug resistance. Several isoforms of human GSTs are present and they are expressed in almost all the organs. Specific expression levels of GSTs in various organs are collected from the human transcriptome data and analysis of the organ-specific expression of GST isoforms is carried out. The variations in the level of expressions of GST isoforms are statistically significant. The GST expression differs in diseased conditions as reported by many investigators and some of the isoforms of GSTs are disease markers or drug targets. Structure analysis of various isoforms is carried out and literature mining has been performed to identify the differences in the active sites of the GSTs. The xenobiotic binding H site is classified into H1, H2, and H3 and the differences in the amino acid composition, the hydrophobicity and other structural features of H site of GSTs are discussed. The existing inhibition strategies are compared. The advent of rational drug design, mechanism-based inhibition strategies, availability of high-throughput screening, target specific, and selective inhibition of GST isoforms involved in drug resistance could be achieved for the reversal of drug resistance and aid in the treatment of diseases.

Intermittent search strategies

NASA Astrophysics Data System (ADS)

Bénichou, O.; Loverdo, C.; Moreau, M.; Voituriez, R.

2011-01-01

This review examines intermittent target search strategies, which combine phases of slow motion, allowing the searcher to detect the target, and phases of fast motion during which targets cannot be detected. It is first shown that intermittent search strategies are actually widely observed at various scales. At the macroscopic scale, this is, for example, the case of animals looking for food; at the microscopic scale, intermittent transport patterns are involved in a reaction pathway of DNA-binding proteins as well as in intracellular transport. Second, generic stochastic models are introduced, which show that intermittent strategies are efficient strategies that enable the minimization of search time. This suggests that the intrinsic efficiency of intermittent search strategies could justify their frequent observation in nature. Last, beyond these modeling aspects, it is proposed that intermittent strategies could also be used in a broader context to design and accelerate search processes.

Predictive models of control strategies involved in containing indoor airborne infections.

Chen, S-C; Chang, C-F; Liao, C-M

2006-12-01

Recently developed control measure modeling approaches for containing airborne infections, including engineering controls with respiratory protection and public health interventions, are readily amenable to an integrated-scale analysis. Here we show that such models can be derived from an integrated-scale analysis generated from three different types of functional relationship: Wells-Riley mathematical model, competing-risks model, and Von Foerster equation, both of the key epidemiological determinants involved and of the functional connections between them. We examine mathematically the impact of engineering control measures such as enhanced air exchange and air filtration rates with personal masking combined with public health interventions such as vaccination, isolation, and contact tracing in containing the spread of indoor airborne infections including influenza, chickenpox, measles, and severe acute respiratory syndrome (SARS). If enhanced engineering controls could reduce the basic reproductive number (R0) below 1.60 for chickenpox and 3 for measles, our simulations show that in such a prepared response with public health interventions would have a high probability of containing the indoor airborne infections. Combinations of engineering control measures and public health interventions could moderately contain influenza strains with an R0 as high as 4. Our analysis indicates that effective isolation of symptomatic patients with low-efficacy contact tracing is sufficient to control a SARS outbreak. We suggest that a valuable added dimension to public health inventions could be provided by systematically quantifying transmissibility and proportion of asymptomatic infection of indoor airborne infection. Practical Implications We have developed a flexible mathematical model that can help determine the best intervention strategies for containing indoor airborne infections. The approach presented here is scalable and can be extended to include additional control

2014-11-01

Challenges associated with recruiting and retaining community-based populations in research studies have been recognized yet remain of major concern for researchers. There is a need for exchange of recruitment and retention techniques that inform recruitment and retention strategies. Here, the authors discuss a variety of methods that were successful in exceeding target recruitment and retention goals in a randomized clinical trial of hearing protector use among farm operators. Recruitment and retention strategies were 1) based on a philosophy of mutually beneficial engagement in the research process, 2) culturally appropriate, 3) tailored to the unique needs of partnering agencies, and 4) developed and refined in a cyclical and iterative process. Sponsoring organizations are interested in cost-effective recruitment and retention strategies, particularly relating to culturally and ethnically diverse groups. These approaches may result in enhanced subject recruitment and retention, concomitant containment of study costs, and timely accomplishment of study aims. Copyright © 2014 Elsevier Inc.

Neural substrates of similarity and rule-based strategies in judgment

von Helversen, Bettina; Karlsson, Linnea; Rasch, Björn; Rieskamp, Jörg

2014-01-01

Making accurate judgments is a core human competence and a prerequisite for success in many areas of life. Plenty of evidence exists that people can employ different judgment strategies to solve identical judgment problems. In categorization, it has been demonstrated that similarity-based and rule-based strategies are associated with activity in different brain regions. Building on this research, the present work tests whether solving two identical judgment problems recruits different neural substrates depending on people's judgment strategies. Combining cognitive modeling of judgment strategies at the behavioral level with functional magnetic resonance imaging (fMRI), we compare brain activity when using two archetypal judgment strategies: a similarity-based exemplar strategy and a rule-based heuristic strategy. Using an exemplar-based strategy should recruit areas involved in long-term memory processes to a larger extent than a heuristic strategy. In contrast, using a heuristic strategy should recruit areas involved in the application of rules to a larger extent than an exemplar-based strategy. Largely consistent with our hypotheses, we found that using an exemplar-based strategy led to relatively higher BOLD activity in the anterior prefrontal and inferior parietal cortex, presumably related to retrieval and selective attention processes. In contrast, using a heuristic strategy led to relatively higher activity in areas in the dorsolateral prefrontal and the temporal-parietal cortex associated with cognitive control and information integration. Thus, even when people solve identical judgment problems, different neural substrates can be recruited depending on the judgment strategy involved. PMID:25360099

2011-12-01

A recent experimental study [Traulsen et al., Proc. Natl. Acad. Sci. 107, 2962 (2010)] shows that human strategy updating involves both direct payoff comparison and the cost of switching strategy, which is equivalent to inertia. However, it remains largely unclear how such a predisposed inertia affects 2 × 2 games in a well-mixed population of finite size. To address this issue, the "inertia bonus" (strategy switching cost) is added to the learner payoff in the Fermi process. We find how inertia quantitatively shapes the stationary distribution and that stochastic stability under inertia exhibits three regimes, with each covering seven regions in the plane spanned by two inertia parameters. We also obtain the extended "1/3" rule with inertia and the speed criterion with inertia; these two findings hold for a population above two. We illustrate the above results in the framework of the Prisoner's Dilemma game. As inertia varies, two intriguing stationary distributions emerge: the probability of coexistence state is maximized, or those of two full states are simultaneously peaked. Our results may provide useful insights into how the inertia of changing status quo acts on the strategy evolution and, in particular, the evolution of cooperation.

The emergence of bacterial pathogens resistant to all known antibiotics is a global health crisis. Adding to this problem is that major pharmaceutical companies have shifted away from antibiotic discovery due to low profitability. As a result, the pipeline of new antibiotics is essentially dry and many bacteria now resist the effects of most commonly used drugs. To address this global health concern, citizen science through the Small World Initiative (SWI) was formed in 2012. As part of SWI, students isolate bacteria from their local environments, characterize the strains, and assay for antibiotic production. During the 2015 fall semester at Bowling Green State University, students isolated 77 soil-derived bacteria and genetically characterized strains using the 16S rRNA gene, identified strains exhibiting antagonistic activity, and performed an expanded SWI workflow using transposon mutagenesis to identify a biosynthetic gene cluster involved in toxigenic compound production. We identified one mutant with loss of antagonistic activity and through subsequent whole-genome sequencing and linker-mediated PCR identified a 24.9 kb biosynthetic gene locus likely involved in inhibitory activity in that mutant. Further assessment against human pathogens demonstrated the inhibition of Bacillus cereus, Listeria monocytogenes, and methicillin-resistant Staphylococcus aureus in the presence of this compound, thus supporting our molecular strategy as an effective research pipeline for SWI antibiotic discovery and genetic characterization. © 2017 The Authors.

The purpose of this descriptive comparative study is to compare the levels of decisional involvement of staff nurses between one Midwestern health care system in the United States with a nongovernmental University hospital in Turkey. The Decisional Involvement Scale was used for data collection. U.S. ( n = 163) and Turkey ( n = 50) staff nurses were included in the study. Both samples preferred more decisional involvement than they currently experienced. However, Turkish nurses experienced and preferred lower levels of decisional involvement than the U.S. Shared governance structures may be a strategy used to enhance staff nurse decisional involvement.

Involving young people in health promotion, research and policy-making: practical recommendations.

2018-05-18

Youth is a dynamic and complex transition period in life where many factors jeopardise its present and future health. Youth involvement enables young people to influence processes and decisions that affect them, leading to changes in themselves and their environment (e.g. peers, services, communities and policies); this strategy could be applied to improve health and prevent diseases. Nonetheless, scientific evidence of involving youth in health-related programmes is scarce. The aim of this paper is to describe youth involvement as a health promotion strategy and to compile practical recommendations for health promoters, researchers and policy-makers interested in successful involvement of young people in health-related programmes. These suggestions aim to encourage a positive working synergy between adults and youth during the development, implementation and evaluation of policies, research and/or health promotion efforts that target adolescents.

Effects of strategy sequences and response-stimulus intervals on children's strategy selection and strategy execution: a study in computational estimation.

PubMed

Lemaire, Patrick; Brun, Fleur

2014-07-01

The present study investigates how children's better strategy selection and strategy execution on a given problem are influenced by which strategy was used on the immediately preceding problem and by the duration between their answer to the previous problem and current problem display. These goals are pursued in the context of an arithmetic problem solving task. Third and fifth graders were asked to select the better strategy to find estimates to two-digit addition problems like 36 + 78. On each problem, children could choose rounding-down (i.e., rounding both operands down to the closest smaller decades, like doing 40 + 60 to solve 42 + 67) or rounding-up strategies (i.e., rounding both operands up to the closest larger decades, like doing 50 + 70 to solve 42 + 67). Children were tested under a short RSI condition (i.e., the next problem was displayed 900 ms after participants' answer) or under a long RSI condition (i.e., the next problem was displayed 1,900 ms after participants' answer). Results showed that both strategy selection (e.g., children selected the better strategy more often under long RSI condition and after selecting the poorer strategy on the immediately preceding problem) and strategy execution (e.g., children executed strategy more efficiently under long RSI condition and were slower when switching strategy over two consecutive problems) were influenced by RSI and which strategy was used on the immediately preceding problem. Moreover, data showed age-related changes in effects of RSI and strategy sequence on mean percent better strategy selection and on strategy performance. The present findings have important theoretical and empirical implications for our understanding of general and specific processes involved in strategy selection, strategy execution, and strategic development.

Integrating Terrain Maps Into a Reactive Navigation Strategy

NASA Technical Reports Server (NTRS)

Howard, Ayanna; Werger, Barry; Seraji, Homayoun

2006-01-01

An improved method of processing information for autonomous navigation of a robotic vehicle across rough terrain involves the integration of terrain maps into a reactive navigation strategy. Somewhat more precisely, the method involves the incorporation, into navigation logic, of data equivalent to regional traversability maps. The terrain characteristic is mapped using a fuzzy-logic representation of the difficulty of traversing the terrain. The method is robust in that it integrates a global path-planning strategy with sensor-based regional and local navigation strategies to ensure a high probability of success in reaching a destination and avoiding obstacles along the way. The sensor-based strategies use cameras aboard the vehicle to observe the regional terrain, defined as the area of the terrain that covers the immediate vicinity near the vehicle to a specified distance a few meters away.

Pulmonary arterial hypertension (PAH) is a chronic pulmonary vascular disease characterized by increased pulmonary vascular resistance (PVR) leading to right ventricular (RV) failure. Autonomic nervous system involvement in the pathogenesis of PAH has been demonstrated several years ago, however the extent of this involvement is not fully understood. PAH is associated with increased sympathetic nervous system (SNS) activation, decreased heart rate variability, and presence of cardiac arrhythmias. There is also evidence for increased renin-angiotensin-aldosterone system (RAAS) activation in PAH patients associated with clinical worsening. Reduction of neurohormonal activation could be an effective therapeutic strategy for PAH. Although therapies targeting adrenergic receptors or RAAS signaling pathways have been shown to reverse cardiac remodeling and improve outcomes in experimental pulmonary hypertension (PH)-models, the effectiveness and safety of such treatments in clinical settings have been uncertain. Recently, novel direct methods such as cervical ganglion block, pulmonary artery denervation (PADN), and renal denervation have been employed to attenuate SNS activation in PAH. In this review, we intend to summarize the multiple aspects of autonomic nervous system involvement in PAH and overview the different pharmacological and invasive strategies used to target autonomic nervous system for the treatment of PAH.

Effect of dietary marine lipids on female white bass ova compositions and progeny survival.

PubMed

Lewis, H A; Trushenski, J T; Lane, R L; Kohler, C C

2010-12-01

We evaluated white bass ovum fatty acid composition as well as embryonic and larval survival after varying n-3 and n-6 long-chain polyunsaturated fatty acid (LC-PUFA) concentrations in maternal diets. Diets containing graded levels (0, 33, 66, or 100%) of squid to menhaden oils were fed daily to apparent satiation to female white bass for 8 weeks prior to spawning. Embryonic survival was negatively related to maternal squid oil intake (P=0.015, R2=0.970). Squid oil-fed broodstock produced ova with decreased 20:5n-3 and increased C18 polyunsaturated fatty acid concentrations, largely reflecting the fatty acid profile of squid oil. Within ovum phospholipid, accumulation of 18:2n-6 may have altered biological function resulting in the lower embryonic survival among ova produced from the squid oil-fed broodstock. Our data suggest the importance of feeding white bass broodstock diets high in total n-3 LC-PUFA (at least 4.0% dry matter), and 20:5n-3-rich lipid sources such as menhaden oil can be effectively utilized by female white bass to produce quality ova.

One of the major challenges involved in the Voyager 2 Uranus flyby is to deliver the spacecraft to an appropriate aimpoint at the optimum time, so as to maximize the science return of the mission, while yet keeping propellant expenditure low. An unusual targeting strategy has been devised to satisfy these requirements. Its complexity arises from the great distance of the planet Uranus and the limited performance capabilities of Voyager. This selected strategy is developed in relation to a set of candidate strategies, mission requirements and shifting science objectives. The analysis of these candidates is conducted via a Monte Carlo simulation, the results of which yield data for the comparative evaluation and eventual and selection of the actual targeting strategy to be employed.

The success of learning involves adequate strategies. Those inspired on andragogy, which is the science of teaching adults, seem to be ideal for the nursing undergraduate subject "projects", with a focus on the administration of physical resources for nursing. This study reports teaching strategies that try to estimulate the acquisition of competences that make the nurse capable of a dialogue on projects with a multiprofessional team. The strategy involved a workshop composed by four stages: reading of projects, health assistance institute (HAI) attributions, notions on physical scaling strategies and development of a glossary. The strategy, proposed by a graduate student in the subject "Strategies to the teaching of Administration", was tested through practical application, evaluated and approved by graduate students and teachers. The conditions for its implementation are working with few students, availability of proper classrooms and equipment, and partnership with HAIs.

Marketing strategies nurses can employ to promote health.

PubMed

McCormack, D

1994-01-01

Marketing strategies are employed to ensure the success of new products, services or programs. Both profit and non-profit organizations have used social marketing strategies to inform, to motivate interest, and to engage the involvement of the consumer. A client-dependent health care system did not find it necessary to market services, but a health care system that encourages clients to choose the most appropriate health promotion service available must market services. Nurses are in the business of promoting the health of clients. Therefore, it is essential that nurses become familiar with, and involved in, the development of marketing plans and strategies. The connection between the four variables of the marketing mix (product, promotion, place, and price) and promoting the health of clients is described. A case example recapitulating the marketing strategies employed to raise public awareness of a self-help group for family caregivers is related, the marketing response is evaluated, and future recommendations are proposed.

Effects of HBV Genetic Variability on RNAi Strategies

PubMed Central

Panjaworayan, Nattanan; Brown, Chris M.

2011-01-01

RNAi strategies present promising antiviral strategies against HBV. RNAi strategies require base pairing between short RNAi effectors and targets in the HBV pregenome or other RNAs. Natural variation in HBV genotypes, quasispecies variation, or mutations selected by the RNAi strategy could potentially make these strategies less effective. However, current and proposed antiviral strategies against HBV are being, or could be, designed to avoid this. This would involve simultaneous targeting of multiple regions of the genome, or regions in which variation or mutation is not tolerated. RNAi strategies against single genotypes or against variable regions of the genome would need to have significant other advantages to be part of robust therapies. PMID:21760994

As no health system can afford to provide all possible services and treatments for the people it serves, each system must set priorities. Priority setting decision makers are increasingly involving the public in policy making. This study focuses on public engagement in a key priority setting context that plagues every health system around the world: wait list management. The purpose of this study is to describe and evaluate priority setting for the Ontario Wait Time Strategy, with special attention to public engagement. This study was conducted at the Ontario Wait Time Strategy in Ontario, Canada which is part of a Federal-Territorial-Provincial initiative to improve access and reduce wait times in five areas: cancer, cardiac, sight restoration, joint replacements, and diagnostic imaging. There were two sources of data: (1) over 25 documents (e.g. strategic planning reports, public updates), and (2) 28 one-on-one interviews with informants (e.g. OWTS participants, MOHLTC representatives, clinicians, patient advocates). Analysis used a modified thematic technique in three phases: open coding, axial coding, and evaluation.

AIM This study evaluated two strategies to facilitate involvement in Alcoholics Anonymous (AA) – a 12-step-based directive approach and a motivational enhancement approach – during skills-focused individual treatment. DESIGN Randomized controlled trial with assessments at baseline, end of treatment, and 3, 6, 9, and 12 months after treatment. PARTICIPANTS, SETTING, and INTERVENTION 169 alcoholic outpatients (57 women) randomly assigned to one of three conditions: a directive approach to facilitating AA, a motivational enhancement approach to facilitating AA, or treatment as usual with no special emphasis on AA. MEASUREMENTS Self-report of AA meeting attendance and involvement, alcohol consumption (percent days abstinent, percent days heavy drinking), and negative alcohol consequences. FINDINGS Participants exposed to the 12-step directive condition for facilitating AA involvement reported more AA meeting attendance, more evidence of active involvement in AA, and a higher percent days abstinent relative to participants in the treatment-as-usual comparison group. Evidence suggested also that the effect of the directive strategy on abstinent days was partially mediated through AA involvement. The motivational enhancement approach to facilitating AA had no effect on outcome measures. CONCLUSIONS These results suggest that treatment providers can use a 12-step-based directive approach to effectively facilitate involvement in AA and thereby improve client outcome. PMID:19207347

Network reciprocity by coexisting learning and teaching strategies

Tanimoto, Jun; Brede, Markus; Yamauchi, Atsuo

2012-03-01

We propose a network reciprocity model in which an agent probabilistically adopts learning or teaching strategies. In the learning adaptation mechanism, an agent may copy a neighbor's strategy through Fermi pairwise comparison. The teaching adaptation mechanism involves an agent imposing its strategy on a neighbor. Our simulations reveal that the reciprocity is significantly affected by the frequency with which learning and teaching agents coexist in a network and by the structure of the network itself.

The results also revealed that spousal approval was still relevant for women in the use of contraceptives; however, the matrilineal system appears to give more autonomy to women in decision-making. The CHPS strategy was perceived as very helpful with full community participation at all levels of the implementation process. Males were more involved in FP services in communities with functioning CHPS than those without functioning CHPS. Conclusion The CHPS strategy has increased access to FP services but spousal consent was very important in the use of FP services.

Human Life History Strategies.

PubMed

Chua, Kristine J; Lukaszewski, Aaron W; Grant, DeMond M; Sng, Oliver

2017-01-01

Human life history (LH) strategies are theoretically regulated by developmental exposure to environmental cues that ancestrally predicted LH-relevant world states (e.g., risk of morbidity-mortality). Recent modeling work has raised the question of whether the association of childhood family factors with adult LH variation arises via (i) direct sampling of external environmental cues during development and/or (ii) calibration of LH strategies to internal somatic condition (i.e., health), which itself reflects exposure to variably favorable environments. The present research tested between these possibilities through three online surveys involving a total of over 26,000 participants. Participants completed questionnaires assessing components of self-reported environmental harshness (i.e., socioeconomic status, family neglect, and neighborhood crime), health status, and various LH-related psychological and behavioral phenotypes (e.g., mating strategies, paranoia, and anxiety), modeled as a unidimensional latent variable. Structural equation models suggested that exposure to harsh ecologies had direct effects on latent LH strategy as well as indirect effects on latent LH strategy mediated via health status. These findings suggest that human LH strategies may be calibrated to both external and internal cues and that such calibrational effects manifest in a wide range of psychological and behavioral phenotypes.

An independent race model involving an abort and re-plan strategy explains reach redirecting movements during planning and execution.

2018-03-01

Although race models have been extensively used to study inhibitory control, the mechanisms that enable change of reach plans in the context of race models remain unexplored. We used a redirect task in which targets occasionally changed their locations to study the control of reaching movements during movement planning and execution phases. We tested nine different race model architectures that could explain the redirect behavior of reaching movements. We show that an independent GO-STOP-GO model that reflects a plan-abort-re-plan strategy involving non-interacting elements successfully explained the various behavioral measures such as the compensation function and the pattern of error response reaction times. By extending the same race model to the execution phase, we could explain the extent and the pattern of hypometric trials. Interestingly, the race model also provided evidence that redirecting a movement during planning and execution shared the same inhibitory mechanism. Taken together, this study demonstrates the applicability of an independent race model to understand the computational mechanisms underlying the control of reach movements. © 2018 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

Slum upgrading strategies involving physical environment and infrastructure interventions and their effects on health and socio-economic outcomes.

2013-01-31

Slums are densely populated, neglected parts of cities where housing and living conditions are exceptionally poor. In situ slum upgrading, at its basic level, involves improving the physical environment of the existing area, such as improving and installing basic infrastructure like water, sanitation, solid waste collection, electricity, storm water drainage, access roads and footpaths, and street lighting, as well as home improvements and securing land tenure. To explore the effects of slum upgrading strategies involving physical environment and infrastructure interventions on the health, quality of life and socio-economic wellbeing of urban slum dwellers in low and middle income countries (LMIC). Where reported, data were collected on the perspectives of slum dwellers regarding their needs, preferences for and satisfaction with interventions received. We searched for published and unpublished studies in 28 bibliographic databases including multidisciplinary (for example Scopus) and specialist databases covering health, social science, urban planning, environment and LMIC topics. Snowballing techniques included searching websites, journal handsearching, contacting authors and reference list checking. Searches were not restricted by language or publication date. We included studies examining the impact of slum upgrading strategies involving physical environment or infrastructure improvements (with or without additional co-interventions) on the health, quality of life and socio-economic wellbeing of LMIC urban slum dwellers. Randomised controlled trials (RCTs), controlled before and after studies (CBAs) and interrupted time series (ITS) were eligible for the main analysis. Controlled studies with only post-intervention data (CPI) and uncontrolled before and after (UBA) studies were included in a separate narrative to examine consistency of results and to supplement evidence gaps in the main analysis. Two authors independently extracted data and assessed risk of bias

Game theory outlines optimal response strategies during mixed-strategy competitions. The neural processes involved in choosing individual strategic actions, however, remain poorly understood. Here, we tested whether the superior colliculus (SC), a brain region critical for generating sensory-guided saccades, is also involved in choosing saccades under strategic conditions. Monkeys were free to choose either of two saccade targets as they competed against a computer opponent during the mixed-strategy game "matching pennies." The accuracy with which presaccadic SC activity predicted upcoming choice gradually increased in the time leading up to the saccade. Probing the SC with suprathreshold stimulation demonstrated that these evolving signals were functionally involved in preparing strategic saccades. Finally, subthreshold stimulation of the SC increased the likelihood that contralateral saccades were selected. Together, our results suggest that motor regions of the brain play an active role in choosing strategic actions rather than passively executing those prespecified by upstream executive regions.

Postgenomic strategies in antibacterial drug discovery.

During the last decade the field of antibacterial drug discovery has changed in many aspects including bacterial organisms of primary interest, discovery strategies applied and pharmaceutical companies involved. Target-based high-throughput screening had been disappointingly unsuccessful for antibiotic research. Understanding of this lack of success has increased substantially and the lessons learned refer to characteristics of targets, screening libraries and screening strategies. The 'genomics' approach was replaced by a diverse array of discovery strategies, for example, searching for new natural product leads among previously abandoned compounds or new microbial sources, screening for synthetic inhibitors by targeted approaches including structure-based design and analyses of focused libraries and designing resistance-breaking properties into antibiotics of established classes. Furthermore, alternative treatment options are being pursued including anti-virulence strategies and immunotherapeutic approaches. This article summarizes the lessons learned from the genomics era and describes discovery strategies resulting from that knowledge.

Boosting cooperation by involving extortion in spatial prisoner's dilemma games

Wu, Zhi-Xi; Rong, Zhihai

We study the evolution of cooperation in spatial prisoner's dilemma games with and without extortion by adopting the aspiration-driven strategy updating rule. We focus explicitly on how the strategy updating manner (whether synchronous or asynchronous) and also the introduction of extortion strategy affect the collective outcome of the games. By means of Monte Carlo simulations as well as dynamical cluster techniques, we find that the involvement of extortioners facilitates the boom of cooperators in the population (and whom can always dominate the population if the temptation to defect is not too large) for both synchronous and asynchronous strategy updating, in stark contrast to the other case, where cooperation is promoted for an intermediate aspiration level with synchronous strategy updating, but is remarkably inhibited if the strategy updating is implemented asynchronously. We explain the results by configurational analysis and find that the presence of extortion leads to the checkerboard-like ordering of cooperators and extortioners, which enable cooperators to prevail in the population with both strategy updating manners. Moreover, extortion itself is evolutionary stable, and therefore acts as the incubator for the evolution of cooperation.

Over the last 20 years, quality improvement in health has become an important strategy in health services in many countries. With the emphasis on quality health care, there has been a shift in social paradigms towards including service users in their own health on different levels. There is growing evidence in literature on the positive impact on health outcomes where patients are active participants in their personal care. There is however less information available on the broader influence of users on improvement in systems. The objective of this review was to identify the barriers and enablers to patients being involved in quality improvement efforts directed towards their own health care. This review considered studies that included adults and children of any age experiencing any health problem.The review considered studies that explored patient or user participation in quality improvement and the factors enabling and hindering this processThe qualitative component of this review considered studies that focused on qualitative data, including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research and feminist research. Other texts such as opinion papers and reports were also considered. The search strategy aimed to find both published and unpublished studies. A three-step search strategy was utilized in this review. The searches using all identified keywords and index terms included the databases PubMed, PsycINFO, Medline, Scopus, EBSCOhost and CINAHL.Qualitative, text and opinion papers were considered for inclusion in this review.Closely related concepts like community involvement, family involvement, patients' involvement in their own care (for example, in the case of shared decision making), and patient centeredness in the context of a consultation were excluded. Qualitative and textual papers selected for retrieval were assessed by two independent reviewers for authenticity prior to inclusion in the review using

Aging and List-Wide Modulations of Strategy Execution:A Study in Arithmetic.

PubMed

Hinault, Thomas; Lemaire, Patrick

2017-01-01

Background/Study Context: This study aimed at further our understanding of the cognitive processes involved during strategy execution, and how the processes involved change with age. More specifically, the main goal was to investigate whether poorer-strategy effects (i.e., poorer performance when a cued strategy is not the best) and sequential modulations of poorer-strategy effects (i.e., decreased poorer-strategy effects on current problems following poorer-strategy problems compared with after better-strategy problems) are influenced by proportions of poorer-strategy problems. We used a computational estimation task (i.e., providing approximate products to two-digit multiplication problems such as 38 × 74) with problems sets including 75%, 50%, or 25% of poorer-strategy problems (i.e., participants have to estimate products with another strategy than the better strategy). The remaining problems were cued with the better strategy. Age-related differences were also investigated. We found that proportions of poorer-strategy problems influenced sequential modulations of poorer-strategy effects. Indeed, sequential modulations of poorer-strategy effects were larger when proportions of poorer-strategy problems were equal than unequal. Moreover, proportion effects were different for young and older adults, as older adults benefited more from low proportions of poorer-strategy problems compared with young adults. These findings have important implications regarding cognitive control mechanisms underlying both list-wide and trial-to-trial modulations of strategy execution, and how these processes change during aging.

Objectives Patient-reported experience measures are increasingly being used to routinely monitor the quality of care. With the increasing attention on such measures, hospital managers seek ways to systematically improve patient experience across hospital departments, in particular where outcomes are used for public reporting or reimbursement. However, it is currently unclear whether hospitals with more mature quality management systems or stronger focus on patient involvement and patient-centered care strategies perform better on patient-reported experience. We assessed the effect of such strategies on a range of patient-reported experience measures. Materials and Methods We employed a cross-sectional, multi-level study design randomly recruiting hospitals from the Czech Republic, France, Germany, Poland, Portugal, Spain, and Turkey between May 2011 and January 2012. Each hospital contributed patient level data for four conditions/pathways: acute myocardial infarction, stroke, hip fracture and deliveries. The outcome variables in this study were a set of patient-reported experience measures including a generic 6-item measure of patient experience (NORPEQ), a 3-item measure of patient-perceived discharge preparation (Health Care Transition Measure) and two single item measures of perceived involvement in care and hospital recommendation. Predictor variables included three hospital management strategies: maturity of the hospital quality management system, patient involvement in quality management functions and patient-centered care strategies. We used directed acyclic graphs to detail and guide the modeling of the complex relationships between predictor variables and outcome variables, and fitted multivariable linear mixed models with random intercept by hospital, and adjusted for fixed effects at the country level, hospital level and patient level.

They're nominally and ultimately responsible for strategy, but today's CEOs have less and less time to devote to it. As a result, CEOs are appointing "chief strategy officers"--executives specifically tasked with creating, communicating, executing, and sustaining a company's strategic initiatives. In this article, three authors from Accenture share the results of their research on this emerging organizational role. The typical CSO or top strategy executive is not a pure strategist, conducting long-range planning in relative isolation. Most CSOs consider themselves doers first, with the mandate, credentials, and desire to act as well as advise. They are seasoned executives with a strong strategy orientation who have usually worn many operations hats before taking on the role. Strategy executives are charged with three critical jobs that together form the very definition of strategy execution. First, they must clarify the company's strategy for themselves and for every business unit and function, ensuring that all employees understand the details of the strategic plan and how their work connects to corporate goals. Second, CSOs must drive immediate change. The focus of the job almost always quickly evolves from creating shared alignment around a vision to riding herd on the ensuing change effort. Finally, a CSO must drive decision making that sustains organizational change. He or she must be that person who, in the CEO's stead, can walk into any office and test whether the decisions being made are aligned with the strategy and are creating the desired results. When decisions below the executive suite aren't being made in accordance with strategy, much of the CSO's job involves learning why and quickly determining whether to stay the course or change tack.

Knowledge about the relation between user involvement in the provision of assistive technology and outcomes of assistive technology use is a prerequisite for the development of efficient service delivery strategies. However, current knowledge is limited, particularly from low-income countries where affordability is an issue. The objective was therefore to explore the relation between outcomes of assistive technology use and user involvement in the service delivery process in Bangladesh. Using structured interviews, data from 136 users of hearing aids and 149 users of manual wheelchairs were collected. Outcomes were measured using the International Outcome Inventory for Hearing Aids (IOI-HA), which was adapted for wheelchair users. Predictors of user involvement included preference, measurement and training. Users reported outcomes comparable to those found in other high- and low-income countries. User involvement increased the likelihood for reporting better outcomes except for measurement among hearing aid users. The findings support the provision of assistive technology as a strategy to improve the participation of people with disabilities in society. They also support current policies and guidelines for user-involvement in the service delivery process. Simplified strategies for provision of hearing aids may be explored.

The theory of active involvement: processes underlying interventions that engage adolescents in message planning and/or production.

Adolescence is a time of increased risk taking, and recent intervention strategies have included adolescents planning or producing antirisk messages for their peers. Although these projects may generate enthusiasm, we know little about message planning or production as a strategy for changing adolescent decision-making and behavior. This article articulates the Theory of Active Involvement (TAI) to describe and explain the processes through which these active involvement interventions influence adolescents. TAI is based on social cognitive theory's notion of self-regulation and examines multiple perspective taking and activating the self-reflection processes. The theory specifically describes the process of cognitive changes experienced by participants in active involvement interventions. The sequence is conceptualized as starting when engagement with the intervention (arousal and involvement) produces skill and knowledge gains (immediate outcomes) that lead to reflection (perceived discrepancy) and then other cognitions (expectancies, norms, intentions), with the ultimate outcome being behavior change. Engaging the target audience in a process of self-reflection is conceptualized as the crucial ingredient for meaningful and sustainable change in cognitions and behavior. This article provides valuable insight into how active involvement strategies function and how to best design these interventions, particularly those targeting adolescents.

2011-01-01

Nurses involved in whistleblowing often face economic and emotional retaliation, victimization and abuse. Yet for many nurses, one major part of their whistleblowing experience is the negative impact it has on their families. This paper reports findings from a qualitative study pertaining to the effects of whistleblowing on family life from the perspective of the nurses. Using a narrative inquiry approach, fourteen nurses were interviewed who were directly involved in whistleblowing complaints. Data analysis drew out three themes: strained relationships with family members, dislocation of family life, and exposing family to public scrutiny. The harm caused to the nurses involved in a whistleblowing event is not restricted to one party but to all those involved, as the harrowing experience and its consequences are echoed in the family life as well. It is important for organizations to seek strategies that will minimize the harmful effects on nurses' families during whistleblowing events.

There were 2 acclimation periods at the Catherine Creek Acclimation Facility (CCAF) in 2005. During the early acclimation period, 130,748 smolts were delivered from Lookingglass Hatchery (LGH) on 7 March. This group contained progeny of both the captive (53%) and conventional broodstock programs. The size of the fish at delivery was 23.9 fish/lb. Volitional releases began 14 March 2005 and ended 27 March with an estimated total (based on PIT tag detections of 3,187) of 29,402 fish leaving the raceways. This was 22.5% of the total fish delivered. Fish remaining in the raceways after volitional release were forced out. Hourlymore » detections of PIT-tagged fish showed that most of the fish left around 1900 hours. The size of the fish just before the volitional release was 23.9 and the size of the fish remaining just before the forced release was 23.2 fish/lb. The total mortality for the acclimation period was 204 (0.16%). The total number of fish released from the acclimation facility during the early period was 130,544. During the second acclimation period 59,100 smolts were delivered from LGH on 28 March. This group was comprised entirely of progeny from the conventional broodstock program. The size of the fish at delivery was 21.8 fish/lb. Volitional releases began 3 April 2005 and ended with a force out emergency release on 7 April. The size of the fish just before the volitional release was 21.8. The total mortality for the acclimation period was 64 (0.11 %). The total number of fish released from the acclimation facility during the late period was 59,036. There was only 1 planned acclimation period at the Upper Grande Ronde Acclimation Facility (UGRAF) in 2005. During the early acclimation period 105,418 smolts were delivered from LGH on 8 March. This group was comprised entirely of progeny from the conventional broodstock program. The size of the fish at delivery was 21.0 fish/lb.

This report satisfies the requirement that an annual report be submitted for FY 2003. The Grande Ronde Basin Spring Chinook Salmon Captive Broodstock Project is designed to rapidly increase numbers of salmon in stocks that are in imminent danger of extirpation. Parr are captured in Catherine Creek, upper Grande Ronde River and Lostine River and reared to adulthood in captivity. Upon maturation, these fish are spawned (within stocks) and their progeny reared to smoltification before being released into themore » natal stream of their parents. This program is co-managed by ODFW, National Marine Fisheries Service, Nez Perce Tribe and Confederated Tribes of the Umatilla Indian Reservation. This report covers activities conducted and provides data analyses for the Grande Ronde Spring Chinook Salmon Captive broodstock Program from 1 January--31 December 2003. Since the fiscal year ends in the middle of the spawning period, an annual report based on calendar year is more logical. This document is the FY 2003 annual report.

Genetic variation assessed with microsatellites in mass selection lines of the Pacific oyster ( Crassostrea gigas) in China

2016-12-01

Four successive mass selection lines of the Pacific oyster, Crassostrea gigas, selected for faster growth in breeding programs in China were examined at ten polymorphic microsatellite loci to assess the level of allelic diversity and estimate the effective population size. These data were compared with those of their base population. The results showed that the genetic variation of the four generations were maintained at high levels with an average allelic richness of 18.8-20.6, and a mean expected heterozygosity of 0.902-0.921. They were not reduced compared with those of their base population. Estimated effective population sizes based on temporal variances in microsatellite frequencies were smaller to that of sex ratio-corrected broodstock count estimates. Using a relatively large number of broodstock and keeping an equal sex ratio in the broodstock each generation may have contributed to retaining the original genetic diversity and maintaining relatively large effective population size. The results obtained in this study showed that the genetic variation was not affected greatly by mass selection progress and high genetic variation still existed in the mass selection lines, suggesting that there is still potential for increasing the gains in future generations of C. gigas. The present study provided important information for future genetic improvement by selective breeding, and for the design of suitable management guidelines for genetic breeding of C. gigas.

Streptococcus agalactiae and Strep. iniae are bacterial pathogens that cause streptococcosis in many fish species. An accelerated colorimetric loop-mediated isothermal amplification (LAMP) assay with pre-addition of calcein was established, and the transmission and detection of Strep. agalactiae and Strep. iniae in tilapia under natural aquatic environment were investigated. A positive reaction was observed by a colour change from orange to green through the naked eyes after completion at 63°C for 30 min with 10 times higher sensitivity than that of nested PCR assays and without cross-amplification with other fish bacterial pathogens. All sample types of Nile and red tilapia (broodstock, fertilized egg, fry) were Strep. agalactiae- and Strep. iniae positive by this new method, implying that they could be vertically transmitted. With its application for screening broodstock and fry before stocking and for monitoring fish health in grow-out ponds, the method would become very useful in fish farming industry. The application of colorimetric LAMP with pre-addition of calcein offers simple, rapid and sensitive technique with applicability for small field laboratories. This technique explored the possible vertical transmission mode of Strep. agalactiae and Strep. iniae under natural aquatic environment. It could be such preliminary data provided for the screening broodstock before breeding and/or the specific-pathogen-free production. © 2013 The Society for Applied Microbiology.

Prescribing Errors Involving Medication Dosage Forms

2002-01-01

CONTEXT Prescribing errors involving medication dose formulations have been reported to occur frequently in hospitals. No systematic evaluations of the characteristics of errors related to medication dosage formulation have been performed. OBJECTIVE To quantify the characteristics, frequency, and potential adverse patient effects of prescribing errors involving medication dosage forms . DESIGN Evaluation of all detected medication prescribing errors involving or related to medication dosage forms in a 631-bed tertiary care teaching hospital. MAIN OUTCOME MEASURES Type, frequency, and potential for adverse effects of prescribing errors involving or related to medication dosage forms. RESULTS A total of 1,115 clinically significant prescribing errors involving medication dosage forms were detected during the 60-month study period. The annual number of detected errors increased throughout the study period. Detailed analysis of the 402 errors detected during the last 16 months of the study demonstrated the most common errors to be: failure to specify controlled release formulation (total of 280 cases; 69.7%) both when prescribing using the brand name (148 cases; 36.8%) and when prescribing using the generic name (132 cases; 32.8%); and prescribing controlled delivery formulations to be administered per tube (48 cases; 11.9%). The potential for adverse patient outcome was rated as potentially “fatal or severe” in 3 cases (0.7%), and “serious” in 49 cases (12.2%). Errors most commonly involved cardiovascular agents (208 cases; 51.7%). CONCLUSIONS Hospitalized patients are at risk for adverse outcomes due to prescribing errors related to inappropriate use of medication dosage forms. This information should be considered in the development of strategies to prevent adverse patient outcomes resulting from such errors. PMID:12213138

Cost-Effectiveness of Osteoporosis Screening Strategies for Men

Nayak, Smita; Greenspan, Susan L.

2016-01-01

Osteoporosis affects many men, with significant morbidity and mortality. However, the best osteoporosis screening strategies for men are unknown. We developed an individual-level state-transition cost-effectiveness model with a lifetime time horizon to identify the cost-effectiveness of different osteoporosis screening strategies for U.S. men involving various screening tests (dual-energy x-ray absorptiometry (DXA); the Osteoporosis Self-Assessment Tool (OST); or a fracture risk assessment strategy using age, femoral neck bone mineral density (BMD), and Vertebral Fracture Assessment (VFA)); screening initiation ages (50, 60, 70, or 80); and repeat screening intervals (5 years or 10 years). In base-case analysis, no screening was a less effective option than all other strategies evaluated; furthermore, no screening was more expensive than all strategies that involved screening with DXA or the OST risk assessment instrument, and thus no screening was “dominated” by screening with DXA or OST at all evaluated screening initiation ages and repeat screening intervals. Screening strategies that most frequently appeared as most cost-effective in base-case analysis and one-way sensitivity analyses when assuming willingness-to-pay of $50,000/QALY or $100,000/QALY included screening initiation at age 50 with the fracture risk assessment strategy and repeat screening every 10 years; screening initiation at age 50 with fracture risk assessment and repeat screening every 5 years; and screening initiation at age 50 with DXA and repeat screening every 5 years. In conclusion, expansion of osteoporosis screening for U.S. men to initiate routine screening at age 50 or 60 would be expected to be effective and of good value for improving health outcomes. A fracture risk assessment strategy using variables of age, femoral neck BMD, and VFA is likely to be the most effective of the evaluated strategies within accepted cost-effectiveness parameters. DXA and OST are also reasonable

Towards the Implementation of the GEOSS Water Strategy

Lawford, R. G.; Cripe, D.

2014-12-01

Early in 2014, the Group on Earth Observations (GEO) adopted the GEOSS (Global Earth Observation System of Systems) Water Strategy as a potential guide for GEO-related water activities over the next decade. The Water Strategy outlines water-related issues and opportunities that fit within the general GEOSS framework that will be developed over the next decade (2016-2025). Implementation of a water strategy within the GEOSS framework can be complex because GEO Members and Participating Organizations contribute to GEO on a voluntary basis. In spite of these limitations efforts to consolidate an implementation plan have made significant advances during the past nine months. Progress towards the final GEOSS Water Strategy Implementation Plan will be reported and gaps in the plan will be identified. Specific responses to the strategy will address the need for user engagement, the development of integrated of data products, model hierarchies and user support systems, and the research that will be needed to expand the capabilities of GEOSS and its water services. One challenge for the implementation plan involves building a framework from the diverse and wide range of activities and opportunities presented by GEO Members and Participating Organizations. The priority themes within the GEO Water Strategy are being used to provide more focus for new initiatives.

Posters as assessment strategies: focusing on service users.

PubMed

Crawley, Loretta; Frazer, Kate

This article debates whether posters as an assessment strategy in health professionals' education programmes can benefit learners, academics, and service users. Evidence suggests that service-user involvement benefits learning by developing students' communication, partnership and advocacy skills. The authors debate the value of posters as an assessment strategy in postgraduate diploma nursing programmes delivered in an Irish School of Nursing, Midwifery and Health Systems. It is argued that assessment strategies should not only examine programme theory and practice but should also benefit the people that will be using the service. Although the assessment strategy used in these programmes aimed to benefit service users, additional work is required for assessment to be truly inclusive of service users.

Patients as educators (teaching intimate physical examination) first appeared in the 1960s. Since then, rationales for the active involvement of patients as educators have been well articulated. There is great potential to promote the learning of patient-centred practice, interprofessional collaboration, community involvement, shared decision making and how to support self-care. We reviewed and summarised the literature on active patient involvement in health professional education. A synthesis of the literature reveals increasing diversity in the ways in which patients are involved in education, but also the movement's weaknesses. Most initiatives are 'one-off' events and are reported as basic descriptions. There is little rigorous research or theory of practice or investigation of behavioural outcomes. The literature is scattered and uses terms (such as 'patient'!) that are contentious and confusing. We propose future directions for research and development, including a taxonomy to facilitate dialogue, an outline of a research strategy and reference to a comprehensive bibliography covering all health and human services.

A novel write strategy for rewritable dual-layer digital versatile discs (DVDs) was studied. This new strategy involves the erase top pulse which is included in the conventional write strategy for single-layer DVDs in present market. By thermal calculations, it was confirmed that this erase top pulse has an affect on the rapid heating of recording films. We observed that this new strategy enabled the improvement in data qualities on the layer near the laser incident (L0) effectively in 2 × and 4 ×-speed recordings even if L0 had a high optical transparency. Furthermore we also demonstrated a combination of what with the 2T-period strategy on the layer far from the laser incident (L1) realized a well-balanced signal performance for dual-layer DVD media.

Hospital survival strategies for the 1980s.

PubMed

Bonney, R S

1983-09-01

Survival strategies for hospitals and hospital pharmacy departments are presented, and one hospital's development into a health-services system is described. Financial and competitive pressures are forcing institutions to develop new strategies for survival. The primary institutional strategy is diversification--both horizontal and vertical. Diversification can assist in the hospital's growth, increase its asset and revenue bases, and lead to the development of a health-care delivery system. Marketing to physicians and developing information systems are also critical strategies under a prospective payment system. Institutions will need to know the cost of providing care for specific diagnosis-related groups. Strategies must be employed to develop incentives to reduce inpatient acute-care services and to increase productivity. Physicians should be involved in all of the institutional strategies. Strategies for the pharmacy department are basically the same. Pharmacy departments should develop programs to reduce drug use (especially antibiotic use) and information systems that show the actual cost of providing services by diagnosis. The major corporate restructuring and diversification efforts of one hospital are described. The future of hospitals and pharmacy departments will depend on the successful application of the strategies discussed.

A simple strategy for jumping straight up.

PubMed

Hemami, Hooshang; Wyman, Bostwick F

2012-05-01

Jumping from a stationary standing position into the air is a transition from a constrained motion in contact with the ground to an unconstrained system not in contact with the ground. A simple case of the jump, as it applies to humans, robots and humanoids, is studied in this paper. The dynamics of the constrained rigid body are expanded to define a larger system that accommodates the jump. The formulation is applied to a four-link, three-dimensional system in order to articulate the ballistic motion involved. The activity of the muscular system and the role of the major sagittal muscle groups are demonstrated. The control strategy, involving state feedback and central feed forward signals, is formulated and computer simulations are presented to assess the feasibility of the formulations, the strategy and the jump.

Structure and strategies in children's educational television: the roles of program type and learning strategies in children's learning.

PubMed

Linebarger, Deborah L; Piotrowski, Jessica Taylor

2010-01-01

Educational TV has been consistently linked to children's learning. In this research, educational TV characteristics were identified, coded, and tested for their influence on children's program-specific comprehension and vocabulary outcomes. Study 1 details a content analysis of TV features including a program's macrostructure (i.e., narrative or expository) and learning strategies embedded in the macrostructure that support learning in print-based contexts. In Study 2, regression analyses were used to predict outcomes involving 71 second and third graders (average age=7.63 years). Strategies were categorized as organizing, rehearsing, elaborating, or affective in function. Outcomes were uniformly higher for narrative macrostructures. Strategies used in narratives predicted relatively homogenous relations across outcomes, whereas strategies in expositories predicted quite heterogeneous relations across outcomes. © 2010 The Authors.

Hypothesis testing in students: Sequences, stages, and instructional strategies

NASA Astrophysics Data System (ADS)

Moshman, David; Thompson, Pat A.

Six sequences in the development of hypothesis-testing conceptions are proposed, involving (a) interpretation of the hypothesis; (b) the distinction between using theories and testing theories; (c) the consideration of multiple possibilities; (d) the relation of theory and data; (e) the nature of verification and falsification; and (f) the relation of truth and falsity. An alternative account is then provided involving three global stages: concrete operations, formal operations, and a postformal metaconstructivestage. Relative advantages and difficulties of the stage and sequence conceptualizations are discussed. Finally, three families of teaching strategy are distinguished, which emphasize, respectively: (a) social transmission of knowledge; (b) carefully sequenced empirical experience by the student; and (c) self-regulated cognitive activity of the student. It is argued on the basis of Piaget's theory that the last of these plays a crucial role in the construction of such logical reasoning strategies as those involved in testing hypotheses.

Greater specification of implementation strategies is a challenge for implementation science, but there is little guidance for delineating the use of multiple strategies involved in complex interventions. The Cardiovascular (CV) Toolkit project entails implementation of a toolkit designed to reduce CV risk by increasing women's engagement in appropriate services. The CV Toolkit project follows an enhanced version of Replicating Effective Programs (REP), an evidence-based implementation strategy, to implement the CV Toolkit across four phases: pre-conditions, pre-implementation, implementation, and maintenance and evolution. Our current objective is to describe a method for mapping implementation strategies used in real time as part of the CV Toolkit project. This method supports description of the timing and content of bundled strategies and provides a structured process for developing a plan for implementation evaluation. We conducted a process of strategy mapping to apply Proctor and colleagues' rubric for specification of implementation strategies, constructing a matrix in which we identified each implementation strategy, its conceptual group, and the corresponding REP phase(s) in which it occurs. For each strategy, we also specified the actors involved, actions undertaken, action targets, dose of the implementation strategy, and anticipated outcome addressed. We iteratively refined the matrix with the implementation team, including use of simulation to provide initial validation. Mapping revealed patterns in the timing of implementation strategies within REP phases. Most implementation strategies involving the development of stakeholder interrelationships and training and educating stakeholders were introduced during the pre-conditions or pre-implementation phases. Strategies introduced in the maintenance and evolution phase emphasized communication, re-examination, and audit and feedback. In addition to its value for producing valid and reliable process

Rational combination strategies to enhance venetoclax activity and overcome resistance in hematologic malignancies.

PubMed

Grant, Steven

2018-06-01

Venetoclax (ABT-199) is a Bcl-2-specific BH3-mimetic that has shown significant promise in certain subtypes of CLL as well as in several other hematologic malignancies. As in the case of essentially all targeted agents, intrinsic or acquired resistance to this agent generally occurs, prompting the search for new strategies capable of circumventing this problem. A logical approach to this challenge involves rational combination strategies designed to disable preexisting or induced compensatory survival pathways. Many of these strategies involve downregulation of Mcl-1, a pro-survival Bcl-2 family member that is not targeted by venetoclax, and which often confers resistance to this agent. Given encouraging clinical results involving venetoclax in both lymphoid and myeloid malignancies, it is likely that such combination approaches will be incorporated into the therapeutic armamentarium for multiple hematologic malignancies in the near future.

To compare the use and effects of enhanced pre-existing coping strategies with the use and effects of coping strategies usually taught in National Health Service (NHS) antenatal education on women's experience of pain and emotions during labour. A between-group comparison of women who chose to attend NHS antenatal education where courses of preparation were randomly assigned to include either a new method of coping strategy enhancement (CSE) or standard taught coping strategies. Two large maternity units in one city in the North of England. 20 women participated in antenatal classes incorporating the CSE method and 21 women participated in antenatal classes incorporating the standard approach to developing coping strategies for labour. Women who attended CSE classes used enhanced coping strategies for a larger proportion of their labour than women who attended standard classes who used taught coping strategies. Birth companions were more involved in women's use of enhanced than taught strategies. Self-efficacy for use of coping strategies and subsequent experiences of pain and emotions during labour were equivalent between groups. An approach based on enhancing pre-existing coping strategies was associated with greater coping strategy use and involvement from the birth companion, and provided benefits to women's overall experience of labour at least equivalent to that associated with standard preparation. Further research should explore this novel approach in larger groups, and for women who may choose not to attend group antenatal preparation.

Researchers function in a complex environment and carry multiple role responsibilities. This environment is prone to various distractions that can derail productivity and decrease efficiency. Effective time management allows researchers to maintain focus on their work, contributing to research productivity. Thus, improving time management skills is essential to developing and sustaining a successful program of research. This article presents time management strategies addressing behaviors surrounding time assessment, planning, and monitoring. Herein, the Western Journal of Nursing Research editorial board recommends strategies to enhance time management, including setting realistic goals, prioritizing, and optimizing planning. Involving a team, problem-solving barriers, and early management of potential distractions can facilitate maintaining focus on a research program. Continually evaluating the effectiveness of time management strategies allows researchers to identify areas of improvement and recognize progress.

Active, sustained involvement of treating physicians, a historical deficit of disease management programs, is a CCI-I program goal. During the last decade, Kaiser Permanente, an integrated health care delivery system with more than 60 years of experience in managing the care of individuals and populations, has applied the chronic care model (CCM) to develop care management strategies for populations of patients with chronic medical conditions. Physician leadership and involvement have been key to successfully incorporating these practices into care. The scope of physician involvement in leading, developing, and delivering chronic illness care management at Kaiser Permanente is described as a basis for identifying opportunities to involve practicing physicians in the CCI-I.

Mercy Medical Center is a 467 bed, not-for-profit teaching hospital affiliated with a multispecialty group practice and health maintenance organization through contractual arrangements. Historically, strategy development was not helping the hospital remain viable while accomplishing its mission. Strategic planning was fragmented, not focused toward concern for balance of the overall product line, total growth of the organization or the best use of resources. The hospital did not involve the affiliated group practice or HMO in its planning. This last case in Chapter One describes the pursuit of synergy through strategy formulation. The case provides a good example of what Kanter describes as a post-entrepreneurial organization, striving for advantage through collaboration and linkage with "PALs."

Wilson, Amy Blank; Farkas, Kathleen; Bonfine, Natalie; Duda-Banwar, Janelle

2018-05-01

This research describes the development of a targeted service delivery approach that tailors the delivery of interventions that target criminogenic needs to the specific learning and treatment needs of justice-involved people with serious mental illnesses (SMIs). This targeted service delivery approach includes five service delivery strategies: repetition and summarizing, amplification, active coaching, low-demand practice, and maximizing participation. Examples of how to apply each strategy in session are provided, as well as recommendations on when to use each strategy during the delivery of interventions that target criminogenic needs. This targeted service delivery approach makes an important contribution to the development of interventions for justice-involved people with SMI by increasing the chances that people with SMI can participate fully in and benefit from these interventions that target criminogenic needs. These developments come at a critical time in the field as the next generation of services for justice-involved people with SMI are being developed.

Dowker, Ann

2014-01-01

Forty-four children between 6;0 and 7;11 took part in a study of derived fact strategy use. They were assigned to addition and subtraction levels on the basis of calculation pretests. They were then given Dowker's (1998) test of derived fact strategies in addition, involving strategies based on the Identity, Commutativity, Addend +1, Addend −1, and addition/subtraction Inverse principles; and test of derived fact strategies in subtraction, involving strategies based on the Identity, Minuend +1, Minuend −1, Subtrahend +1, Subtrahend −1, Complement and addition/subtraction Inverse principles. The exact arithmetic problems given varied according to the child's previously assessed calculation level and were selected to be just a little too difficult for the child to solve unaided. Children were given the answer to a problem and then asked to solve another problem that could be solved quickly by using this answer, together with the principle being assessed. The children also took the WISC Arithmetic subtest. Strategies differed greatly in difficulty, with Identity being the easiest, and the Inverse and Complement principles being most difficult. The Subtrahend +1 and Subtrahend −1 problems often elicited incorrect strategies based on an overextension of the principles of addition to subtraction. It was concluded that children may have difficulty with understanding and applying the relationships between addition and subtraction. Derived fact strategy use was significantly related to both calculation level and to WISC Arithmetic scaled score. PMID:24431996

Carbohydrate Strategies for Injury Prevention

PubMed Central

Schlabach, Gretchen

1994-01-01

Prevention of injury involves identifying risk factors that would predispose one to injury and developing strategies to attenuate or eliminate their presence. Because muscle glycogen depletion is associated with fatigue and injury, it should be treated as a possible risk factor. Muscle glycogen stores are derived almost entirely from carbohydrate intake. Because there is a limited capacity to store muscle glycogen, and because muscle glycogen is the predominant fuel in exercise of moderate to severe intensity, the nutritional focus should be on carbohydrate consumption. Easy-to-follow nutritional strategies should be employed that will maximize muscle glycogen stores and delay the onset of fatigue. Individuals involved in activities lasting less than 60 minutes need to consume an adequate amount of carbohydrate daily and a pre-event meal before the start of the activity. However, individuals participating in activities longer than 60 minutes or participating in activities requiring repeated bouts of high intensity exercise need to: 1) consume an adequate amount of carbohydrate daily, 2) practice carbohydrate loading, 3) consume the pre-event meal, and 4) ingest carbohydrates immediately before, during, and after the activity.

Individual differences in intrinsic brain connectivity predict decision strategy.

Barnes, Kelly Anne; Anderson, Kevin M; Plitt, Mark; Martin, Alex

2014-10-15

When humans are provided with ample time to make a decision, individual differences in strategy emerge. Using an adaptation of a well-studied decision making paradigm, motion direction discrimination, we probed the neural basis of individual differences in strategy. We tested whether strategies emerged from moment-to-moment reconfiguration of functional brain networks involved in decision making with task-evoked functional MRI (fMRI) and whether intrinsic properties of functional brain networks, measured at rest with functional connectivity MRI (fcMRI), were associated with strategy use. We found that human participants reliably selected one of two strategies across 2 days of task performance, either continuously accumulating evidence or waiting for task difficulty to decrease. Individual differences in decision strategy were predicted both by the degree of task-evoked activation of decision-related brain regions and by the strength of pretask correlated spontaneous brain activity. These results suggest that spontaneous brain activity constrains strategy selection on perceptual decisions.

Lipid metabolism-related gene expression pattern of Atlantic bluefin tuna (Thunnus thynnus L.) larvae fed on live prey.

The present study is the first to evaluate lipid metabolism in first-feeding Atlantic bluefin tuna (ABT; Thunnus thynnus L.) larvae fed different live prey including enriched rotifers Brachionus plicatilis and Acartia sp. copepod nauplii from 2 days after hatch. Understanding the molecular basis of lipid metabolism and regulation in ABT will provide insights to optimize diet formulations for this high-value species new to aquaculture. To this end, we investigated the effect of dietary lipid on whole larvae lipid class and fatty acid compositions and the expression of key genes involved in lipid metabolism in first feeding ABT larvae fed different live prey. Additionally, the expression of lipid metabolism genes in tissues of adult broodstock ABT was evaluated. Growth and survival data indicated that copepods were the best live prey for first feeding ABT and that differences in growth performance and lipid metabolism observed between larvae from different year classes could be a consequence of broodstock nutrition. In addition, expression patterns of lipid metabolic genes observed in ABT larvae in the trials could reflect differences in lipid class and fatty acid compositions of the live prey. The lipid nutritional requirements, including essential fatty acid requirements of larval ABT during the early feeding stages, are unknown, and the present study represents a first step in addressing these highly relevant issues. However, further studies are required to determine nutritional requirements and understand lipid metabolism during development of ABT larvae and to apply the knowledge to the commercial culture of this iconic species.

The collapse of Atlantic cod (Gadus morhua) wild populations strongly impacted the Atlantic cod fishery and led to the development of cod aquaculture. In order to improve aquaculture and broodstock quality, we need to gain knowledge of genes and pathways involved in Atlantic cod responses to pathogens and other stressors. The Atlantic Cod Genomics and Broodstock Development Project has generated over 150,000 expressed sequence tags from 42 cDNA libraries representing various tissues, developmental stages, and stimuli. We used this resource to develop an Atlantic cod oligonucleotide microarray containing 20,000 unique probes. Selection of sequences from the full range of cDNA libraries enables application of the microarray for a broad spectrum of Atlantic cod functional genomics studies. We included sequences that were highly abundant in suppression subtractive hybridization (SSH) libraries, which were enriched for transcripts responsive to pathogens or other stressors. These sequences represent genes that potentially play an important role in stress and/or immune responses, making the microarray particularly useful for studies of Atlantic cod gene expression responses to immune stimuli and other stressors. To demonstrate its value, we used the microarray to analyze the Atlantic cod spleen response to stimulation with formalin-killed, atypical Aeromonas salmonicida, resulting in a gene expression profile that indicates a strong innate immune response. These results were further validated by quantitative PCR analysis and comparison to results from previous analysis of an SSH library. This study shows that the Atlantic cod 20K oligonucleotide microarray is a valuable new tool for Atlantic cod functional genomics research.

Patent protection strategies

2010-01-01

It is widely recognized that the pharmaceutical industry faces serious financial challenges. Large numbers of blockbuster drugs are losing patent protection and going generic. The pipeline of new drugs is too sparse to fill the gap and generate a platform for future growth. Moreover, many of the new products are biologics with much narrower target patient populations and comparatively higher prices relative to traditional pharmaceuticals. So now the time has come for pharmaceutical scientists to have a better understanding of patent fundamentals. This need is illustrated by analyses of key scientific and legal issues that arose during recent patent infringement cases involving Prozac, Prilosec, and Buspar. Facing this scenario, the pharmaceutical industry has moved to accelerate drug development process and to adopt at the same time different strategies to extend the life time of the patent monopoly to provide the economic incentives and utilizing it for drug discovery and development. This review covers the need of patent protection and various strategies to extend the patent. PMID:21814422

Clinical assessment of adolescents involved in Satanism.

Satanism is a destructive religion that promises power, dominance, and gratification to its practitioners. Unfortunately, some adolescents are seduced by these promises, often because they feel alienated, alone, angry, and desperate. This article explores the psychosocial needs of adolescents that are often met by participation in Satanic worship. Gratification of these needs, when met, may make leaving the cult a difficult and lengthy process. Included is a method for determining the adolescents' level of involvement and an assessment strategy for the therapeutic evaluation process. A brief overview of clinical intervention is also discussed.

Ocular Involvement of Behçet's Syndrome: a Comprehensive Review.

PubMed

Ozyazgan, Yilmaz; Ucar, Didar; Hatemi, Gulen; Yazici, Yusuf

2015-12-01

Behçet's syndrome (BS) is a vasculitis involving several organ systems including the eyes. Ocular involvement is one of the most disabling complications of BS, causing loss of vision that may progress to blindness if left untreated. The typical form of ocular involvement is a relapsing and remitting panuveitis and retinal vasculitis. Initial attacks may spontaneously improve and subsequently disappear in a few weeks but tend to recur if left untreated. Destructive and recurrent attacks, especially with posterior segment and retina involvement, may cause irreversible ocular structural changes and permanent damage in sensory retina, resulting in loss of vision. The risk of irreversible damage to ocular tissue which may result in loss of vision warrants early and intensive treatment especially in patients at high risk such as young men who tend to follow an aggressive disease course. The management strategy involves rapid suppression of inflammation during the attacks and prevention of recurrent attacks. Local and systemic measures including immunosuppressives, corticosteroids, and biologic agents are used for this purpose. Surgery may be required in selected cases. The prognosis of eye involvement has greatly improved over the last decades with the effective use of immunosuppressives.

In literature, there is evidence that all stakeholders need to be involved in the curricula building process to make sure that health professionals are "educated" to meet the stakeholders' "demands". In Italy, the involvement of stakeholders in the definition of university curricula is ratified by various regulations. To describe the major experiences of stakeholder involvement in nursing education, identify the main stakeholders for nursing education, and the processes in which they are involved. The search strategy included an electronic exploration of the relevant databases. The search terms were: Stakeholders, Curriculum, Nursing Education combined with Boolean operators. The references of the retrieved articles were hand searched for additional related studies. Most of the studies identified were from the United Kingdom, Australia, and the USA. In Italy, no relevant studies were found. The most frequently identified stakeholders were: students, clinicians, educators, nurse managers. They were mainly involved during profound changes in the curricula and the implementation of new educational approaches. Stakeholders are mostly involved in countries with a private funding system for universities. Such funding systems have probably developed in the academia a greater propensity to involve stakeholders, to provide recognition of success when starting new programs, and are perceived more as marketing research. This seems contrary to the spirit of the Italian and European regulatory interventions, which instead, provide a structured commitment to consolidating and expanding the collaboration among universities, users, and the world of labor. This latter collaboration should facilitate internship activities, lifelong learning, and employability of the newly-graduated professionals.

The effectiveness of legislative intervention in the New Zealand market for children's nightclothes as an injury prevention strategy has been reassessed by examining those hospital admissions for the period 1980-8 (with emphasis on the 1985-8 period) in which clothing and/or nightclothes were involved. The profiles of the production of children's nightclothes (1977-86) and domestic heating (1984-8) were also examined. Ninety-five cases of burn injury discharges were identified (1985-8), and of those cases involving clothing 42% involved nightwear (49% 1981-4). Some of the 27% unspecified cases may have also involved nightwear (23%, 1981-4). A very strong linear downward trend for nightwear incidents was noted (chi 2 slope = 31.06, p less than 0.001). Forty-eight percent of cases involved children aged 1-6 years, and 68% involved pajamas. Stoves were the main specified ignition agent for nightclothes (36%). Open fires as a form of household heating decreased from 49% to 34% of households (1984-8). Estimated production of nightdresses in New Zealand also decreased (460,000 to 80,000 units, 1973-86). The pronounced decrease in injuries attributable to ignition of children's nightclothes is likely to be the result of mandatory controls on children's nightclothes, increased use of pyjamas, and a steady decrease in use of open fires and portable electric heaters. The typical injury event portrayed to the public of a girl in front of a heater or open fire needs to be corrected.

Shifting social identities as a strategy for deflecting threatening social comparisons.

PubMed

Mussweiler, T; Gabriel, S; Bodenhausen, G V

2000-09-01

Results of three studies suggest that the multifaceted nature of identity provides a strategic basis for reducing the threat involved in upward social comparisons. After performing worse than a comparison standard, people may strategically emphasize aspects of their identity that differentiate them from the standard, thereby making the standard less relevant for self-evaluation. On the basis of previous research showing that persons low in self-esteem are less likely to make effective use of self-protection strategies, we hypothesized that this strategy of deflecting the threat involved in upward comparison (i.e., decreasing perceived comparability by emphasizing an unshared social identity) would be used primarily by persons who are characteristically high in self-esteem. This pattern was confirmed in three studies. Moreover, use of the strategy was associated with relatively more positive affect following threatening upward comparisons.

The goal of treatment for patients with synchronous liver metastases (SLM) from rectal cancer is to achieve a complete resection of both tumor locations. For patients with symptomatic locally advanced rectal cancer with resectable SLM at diagnosis, our usual strategy has been the rectum first approach (RF). However, since 2014, we advocate for the interval approach (IS) that involves the administration of chemo-radiotherapy followed by the resection of the SLM in the interval of time between rectal cancer radiation and rectal surgery. From 2010 to 2016, 16 patients were treated according to this new strategy and 19 were treated according RF strategy. Data were collected prospectively and analyzed with an intention-to-treat perspective. Complete resection rate, duration of the treatment and morbi-mortality were the main outcomes. The complete resection rate in the IS was higher (100%, n = 16) compared to the RF (74%, n = 14, p = 0.049) and the duration of the strategy was shorter (6 vs. 9 months, respectively, p = 0.006). The incidence of severe complications after liver surgery was 14% (n = 2) in the RF and 0% in the IS (p = 1.000), and after rectal surgery was 24% (n = 4) and 12% (n = 2), respectively (p = 1.000). The IS is a feasible and safe strategy that procures higher level of complete resection rate in a shorter period of time compared to RF strategy.

Limited-sampling strategies for anti-infective agents: systematic review.

PubMed

Sprague, Denise A; Ensom, Mary H H

2009-09-01

Area under the concentration-time curve (AUC) is a pharmacokinetic parameter that represents overall exposure to a drug. For selected anti-infective agents, pharmacokinetic-pharmacodynamic parameters, such as AUC/MIC (where MIC is the minimal inhibitory concentration), have been correlated with outcome in a few studies. A limited-sampling strategy may be used to estimate pharmacokinetic parameters such as AUC, without the frequent, costly, and inconvenient blood sampling that would be required to directly calculate the AUC. To discuss, by means of a systematic review, the strengths, limitations, and clinical implications of published studies involving a limited-sampling strategy for anti-infective agents and to propose improvements in methodology for future studies. The PubMed and EMBASE databases were searched using the terms "anti-infective agents", "limited sampling", "optimal sampling", "sparse sampling", "AUC monitoring", "abbreviated AUC", "abbreviated sampling", and "Bayesian". The reference lists of retrieved articles were searched manually. Included studies were classified according to modified criteria from the US Preventive Services Task Force. Twenty studies met the inclusion criteria. Six of the studies (involving didanosine, zidovudine, nevirapine, ciprofloxacin, efavirenz, and nelfinavir) were classified as providing level I evidence, 4 studies (involving vancomycin, didanosine, lamivudine, and lopinavir-ritonavir) provided level II-1 evidence, 2 studies (involving saquinavir and ceftazidime) provided level II-2 evidence, and 8 studies (involving ciprofloxacin, nelfinavir, vancomycin, ceftazidime, ganciclovir, pyrazinamide, meropenem, and alpha interferon) provided level III evidence. All of the studies providing level I evidence used prospectively collected data and proper validation procedures with separate, randomly selected index and validation groups.

Objectives To describe homicide-followed-by-suicide incidents involving child victims Methods Using 2003–2009 National Violent Death Reporting System data, we characterized 129 incidents based on victim and perpetrator demographic information, their relationships, the weapons/mechanisms involved, and the perpetrators’ health and stress-related circumstances. Results These incidents accounted for 188 child deaths; 69% were under 11 years old, and 58% were killed with a firearm. Approximately 76% of perpetrators were males, and 75% were parents/caregivers. Eighty-one percent of incidents with paternal perpetrators and 59% with maternal perpetrators were preceded by parental discord. Fifty-two percent of incidents with maternal perpetrators were associated with maternal psychiatric problems. Conclusions Strategies that resolve parental conflicts rationally and facilitate detection and treatment of parental mental conditions might help prevention efforts. PMID:23985234

Identification, Characterization, and Mapping of a Novel SNP Associated with Body Color Transparency in Juvenile Red Sea Bream (Pagrus major).

2018-03-23

We previously reported a body color deformity in juvenile red sea bream, which shows transparency in the juvenile stage because of delayed chromatophore development compared with normal individuals, and this finding suggested a genetic cause based on parentage assessments. To conduct marker-assisted selection to eliminate broodstock inheriting the causative gene, developing DNA markers associated with the phenotype was needed. We first conducted SNP mining based on AFLP analysis using bulked-DNA from normal and transparent individuals. One SNP was identified from a transparent-specific AFLP fragment, which significantly associated with transparent individuals. Two alleles (A/G) were observed in this locus, and the genotype G/G was dominantly observed in the transparent groups (97.1%) collected from several production lots produced from different broodstock populations. A few normal individuals inherited the G/G genotype (5.0%), but the A/A and A/G genotypes were dominantly observed in the normal groups. The homologs region of the SNP was searched using a medaka genome database, and intron 12 of the Nell2a gene (located on chromosome 6 of the medaka genome) was highly matched. We also mapped the red sea bream Nell2a gene on the previously developed linkage maps, and this gene was mapped on a male linkage group, LG4-M. The newly found SNP was useful in eliminating broodstock possessing the causative gene of the body color transparency observed in juvenile stage of red sea bream.

The goal of this study was to examine children's involvement in consent sessions for exome sequencing research and associations of involvement with provider and parent communication. Participants included 44 children (8-17 years) from five cohorts who were offered participation in an exome sequencing study. The consent sessions were audiotaped, transcribed, and coded. Providers attempted to facilitate the child's involvement in the majority (73%) of sessions, and most (75%) children also verbally participated. Provider facilitation was strongly associated with likelihood of child participation. These findings underscore that strategies such as asking for children's opinions and soliciting their questions show respect for children and may increase the likelihood that they are engaged and involved in decisions about research participation.

Metabolomic Strategies Involving Mass Spectrometry Combined with Liquid and Gas Chromatography.

Lopes, Aline Soriano; Cruz, Elisa Castañeda Santa; Sussulini, Alessandra; Klassen, Aline

2017-01-01

Amongst all omics sciences, there is no doubt that metabolomics is undergoing the most important growth in the last decade. The advances in analytical techniques and data analysis tools are the main factors that make possible the development and establishment of metabolomics as a significant research field in systems biology. As metabolomic analysis demands high sensitivity for detecting metabolites present in low concentrations in biological samples, high-resolution power for identifying the metabolites and wide dynamic range to detect metabolites with variable concentrations in complex matrices, mass spectrometry is being the most extensively used analytical technique for fulfilling these requirements. Mass spectrometry alone can be used in a metabolomic analysis; however, some issues such as ion suppression may difficultate the quantification/identification of metabolites with lower concentrations or some metabolite classes that do not ionise as well as others. The best choice is coupling separation techniques, such as gas or liquid chromatography, to mass spectrometry, in order to improve the sensitivity and resolution power of the analysis, besides obtaining extra information (retention time) that facilitates the identification of the metabolites, especially when considering untargeted metabolomic strategies. In this chapter, the main aspects of mass spectrometry (MS), liquid chromatography (LC) and gas chromatography (GC) are discussed, and recent clinical applications of LC-MS and GC-MS are also presented.

Kwong, Tru E.; Brachman, Kyle J.

2014-01-01

Relations among linguistic auditory processing, nonlinguistic auditory processing, spelling ability, and spelling strategy choice were examined. Sixty-three undergraduate students completed measures of auditory processing (one involving distinguishing similar tones, one involving distinguishing similar phonemes, and one involving selecting appropriate spellings for individual phonemes). Participants also completed a modified version of a standardized spelling test, and a secondary spelling test with retrospective strategy reports. Once testing was completed, participants were divided into phonological versus nonphonological spellers on the basis of the number of words they spelled using phonological strategies only. Results indicated a) moderate to strong positive correlations among the different auditory processing tasks in terms of reaction time, but not accuracy levels, and b) weak to moderate positive correlations between measures of linguistic auditory processing (phoneme distinction and phoneme spelling choice in the presence of foils) and spelling ability for phonological spellers, but not for nonphonological spellers. These results suggest a possible explanation for past contradictory research on auditory processing and spelling, which has been divided in terms of whether or not disabled spellers seemed to have poorer auditory processing than did typically developing spellers, and suggest implications for teaching spelling to children with good versus poor auditory processing abilities.

A National Palliative Care Strategy for Canada

PubMed Central

2017-01-01

Abstract Objective: To identify barrier to achieving universal access to high quality palliative care in Canada, review published national strategies and frameworks to promote palliative care, examine key aspects that have been linked to successful outcomes, and make recommendations for Canada. Background: In 2014, the World Health Organization called on members to develop and implement policies to ensure palliative care is integrated into national health services. Methods: Rapid review supplemented by the author's personal files, outreach to colleagues within the international palliative care community, review of European Association for Palliative Care publications, and a subsequent search of the table of contents of the major palliative care journals. Results: Frameworks were found for 10 countries ranging from detailed and comprehensive multi-year strategies to more general approaches including laws guaranteeing access to palliative care services for “dying” patients or recommendations for the development of clinical infrastructure. Few formal evaluations were found minimal comparative data exist regarding the quality of care, access to palliative care services, timing of access in the disease trajectory, and patient and family satisfaction with care. Factors that appear to be associated with success include: 1) input and early involvement of senior policy makers; 2) comprehensive strategies that address major barriers to universal access and that involve the key constituents; 3) a focus on enhancing the evidence base and developing a national system of quality reporting; and 4) substantial and sustained government investment. Discussion: Comprehensive national strategies appear to improve access to high quality palliative care for persons with serious illness and their families. Such strategies require sustained government funding and address barriers related to infrastructure, professional and public education, workforce shortages, and an inadequate

To analyse the relationship between coping strategy and occupational stress in rail freight dispatchers. 115 rail freight dispatchers were investigated by using group sampling method, investigation contents included coping strategies, occupational stressors, strains and personalities. The proportion of using coping strategy in rail freight dispatchers is lower. The scores of job future ambiguity, type A behavior and work locus of control in workers with insufficient coping strategy were higher than those in workers with sufficient strategy (P < 0.05 or P < 0.01), but the score of organization commitment score in workers with insufficient coping strategy was lower than those in workers with sufficient strategy (P < 0.05), the differences of scores of some occupational stressor, strain and personality variables between workers with insufficient and those with sufficient in social support, job-family balance, job involvement coping factors of coping strategy were remarkable significant (P < 0.05 or P < 0.01), the differences of scores of occupational stressor, strain and personality variables between workers with insufficient and those with sufficient in ask, logic and time management factors of coping strategy weren't significant (P > 0.05). Logistic regression analysis showed that risk of being job dissatisfaction and daily life stress in workers with insufficient social support coping was three or four times than those with sufficient coping (OR = 3.06 or 4.38, respectively), risk of being daily life stress in workers with insufficient job involvement coping was three times than those with sufficient coping (OR = 3.26). The proportion of using coping strategy in rail freight dispatchers is lower. Coping strategy has influence on the individual's perception of occuaptional stressors, strains and personalities.

This mail survey measured post-traumatic stress symptoms, spiritual and non-spiritual coping strategies, and positive spiritual outcomes following the tragedies of 9/11/01 in a national, random sample of 1,056 Presbyterians. Respondents reported mild to moderate degrees of re-experiencing and hyper-arousal symptoms of post-traumatic stress, unrelated to location or knowing someone involved. People experiencing high stress used greater frequency and variety of both spiritual and non-spiritual types of coping strategies. Positive spiritual outcomes were remarkably related to positive spiritual coping strategies, in contrast to no association with negative coping. This study illustrates the significant degree of post-traumatic stress experienced with vicarious exposure and a wide spectrum of coping strategies used following the major terrorist attacks.

Specific strategies need to be developed with and for parents in order to mobilize parental competencies and contribute to increasing their autonomy and decision-making concerning the care provided to children.

Cognitive strategies in the mental rotation task revealed by EEG spectral power.

PubMed

Gardony, Aaron L; Eddy, Marianna D; Brunyé, Tad T; Taylor, Holly A

2017-11-01

The classic mental rotation task (MRT; Shepard & Metzler, 1971) is commonly thought to measure mental rotation, a cognitive process involving covert simulation of motor rotation. Yet much research suggests that the MRT recruits both motor simulation and other analytic cognitive strategies that depend on visuospatial representation and visual working memory (WM). In the present study, we investigated cognitive strategies in the MRT using time-frequency analysis of EEG and independent component analysis. We scrutinized sensorimotor mu (µ) power reduction, associated with motor simulation, parietal alpha (pα) power reduction, associated with visuospatial representation, and frontal midline theta (fmθ) power enhancement, associated with WM maintenance and manipulation. µ power increased concomitant with increasing task difficulty, suggesting reduced use of motor simulation, while pα decreased and fmθ power increased, suggesting heightened use of visuospatial representation processing and WM, respectively. These findings suggest that MRT performance involves flexibly trading off between cognitive strategies, namely a motor simulation-based mental rotation strategy and WM-intensive analytic strategies based on task difficulty. Flexible cognitive strategy use may be a domain-general cognitive principle that underlies aptitude and spatial intelligence in a variety of cognitive domains. We close with discussion of the present study's implications as well as future directions. Published by Elsevier Inc.

2004-06-01

As part of a broader medical and psychosocial needs assessment in a rural region of northern California, USA, five focus groups were conducted to explore innovative approaches to creating a system of consumer involvement in the delivery of HIV primary care services in the region. A total of five focus groups (n = 30) were conducted with clients from three of five counties in the region with the highest number of HIV patients receiving primary care. Participants were recruited by their HIV case managers. They were adults living with HIV, who were receiving health care, and who resided in a rural mountain region of northern California. Group discussions explored ideas for new strategies and examined traditional methods of consumer involvement, considering ways they could be adapted for a rural environment. Recommendations for consumer involvement included a multi-method approach consisting of traditional written surveys, a formal advisory group, and monthly consumer led social support/informal input groups. Specific challenges discussed included winter weather conditions, transportation barriers, physical limitations, confidentiality concerns, and needs for social support and education. A multiple-method approach would ensure more comprehensive consumer involvement in the programme planning process. It is also evident that methods for incorporating consumer involvement must be adapted to the specific context and circumstances of a given programme.

2015-03-01

Part of the work of a critical care nurse is to manage the threats that arise that could impede efficient and effective job performance. Nurses manage threats by employing various strategies to keep performance high and workload manageable. We investigated strategic threat management by using the Threat-Strategy Interview. Threats frequently involved technology, staff, or organizational components. The threats were managed by a toolbox of multifaceted strategies, the most frequent of which involved staff-, treatment- (patient + technology), examination- (patient + clinician), and patient-oriented strategies. The profile of strategies for a particular threat often leveraged work facets similar to the work facet that characterized the threat. In such cases, the nurse's strategy was directed at eliminating the threat (not working around it). A description at both a domain invariant level - useful for understanding strategic threat management generally - and a description at an operational, specific level - useful for guiding interventions-- are presented. A structural description of the relationship among threats, strategies, and the cues that trigger them is presented in the form of an evidence accumulation framework of strategic threat management.

How commitment and involvement influence the development of strategic consensus in health care organizations: the multidisciplinary approach.

PubMed

Carney, Marie

2007-09-01

The aim of this study was to describe how clinician and non-clinician managers achieved consensus of strategy in hospitals. This was the first empirical study undertaken that investigated the impact of organizational commitment on the strategic involvement-strategic consensus relationship. Clinicians and non-clinician managers hold a pivotal role in health care management from the strategic perspective. The importance of multidisciplinary collaboration is recognized, yet how strategic consensus is achieved amongst health service managers, has not been previously researched. The focus of the professional is often on local concerns rather on the broader organizational strategy. This orientation has led to the charge by health service management that clinicians are not interested in, or do not seek to be involved in strategy development. As half of the clinician group in this study were registered nurses and midwives it is important, for multidisciplinary and interdisciplinary collaboration and for strategic development that this group has an awareness of the importance of strategic involvement and organizational commitment in the attainment of strategic consensus. A descriptive study was undertaken and quantitative data were generated through the survey method. The aims of the study were articulated through hypotheses. Almost 400 middle manager heads of department, working in acute care not-for-profit health service organizations, in the Republic of Ireland, responded. Findings indicated that a stronger relationship existed between consensus and commitment than between involvement and commitment. In addition, when present in the organization, involvement and commitment together were better predictors of consensus than each of those factors on its own, but significantly commitment had a greater impact in predicting consensus than involvement had.

In a sample of 527 academically at-risk youth, we investigated trajectories of friends' and parents' school involvement across ages 12–14 and the joint contributions of these trajectories to adolescents' age 15 school engagement and academic achievement. Girls reported higher levels of friends' and parents' school involvement than boys. Both parents' and friends' school involvement declined across ages 12–14. Combined latent growth models and structural equation models showed effects of the trajectories of friends' and parents' school involvement on adolescents' age 15 school engagement and academic achievement, over and above adolescents' prior performance. These effects were additive rather than interactive. Strategies for enhancing parent involvement in school and students' affiliation with peers who are positively engaged in school are discussed.

2009-11-01

In science education students should come to understand the nature and significance of models. A promising strategy to achieve this goal is using authentic modelling practices as contexts for meaningful learning of models and modelling. An authentic practice is defined as professionals working with common motives and purposes, pertaining to a similar type of procedure and applying relevant knowledge on the modelling issue they work on. In this study we evaluate whether the use of authentic practices initiates adequate students’ involvement. This was done by investigating students’ interests, ownership, familiarity and complexity. In addition, we evaluated students’ expressed modelling procedures in response to the modelling issues. We designed learning tasks which were enacted by a focus group of students. Three primary data sources were used to collect data. Firstly, a group discussion was organised in which students’ reflected on both authentic practices. Secondly, students filled in written questionnaires containing items on affective and cognitive aspects. Thirdly, the realised modelling procedures by students were analysed. The results show that students’ involvement was successfully initiated, evidenced by motivated students, willingness to continue and the completeness and quality of the realised modelling procedures. The design of the learning tasks proved to be successful in realising this involvement. The results obtained in this study support the strategy of using authentic modelling practices as contexts for meaningful learning of models and modelling.

Patient recruitment in primary care research is often a protracted and frustrating process, affecting project timeframes, budget and the dissemination of research findings. Yet, clear guidance on patient recruitment strategies in primary care research is limited. This paper addresses this issue through a systematic review. Articles were sourced from five academic databases - AustHealth, CINAHL, the Cochrane Methodology Group, EMBASE and PubMed/Medline; grey literature was also sourced from an academic library and the Primary Healthcare Research & Information Service (PHCRIS) website. Two reviewers independently screened the articles using the following criteria: (1) published in English, (2) reported empirical research, (3) focused on interventions designed to increase patient recruitment in primary care settings, and (4) reported patient recruitment in primary care settings. Sixty-six articles met the inclusion criteria. Of these, 23 specifically focused on recruitment strategies and included randomised trials (n = 7), systematic reviews (n = 8) and qualitative studies (n = 8). Of the remaining articles, 30 evaluated recruitment strategies, while 13 addressed the value of recruitment strategies using descriptive statistics and/or qualitative data. Among the 66 articles, primary care chiefly included general practice (n = 30); nursing and allied health services, multiple settings, as well as other community settings (n = 30); and pharmacy (n = 6). Effective recruitment strategies included the involvement of a discipline champion, simple patient eligibility criteria, patient incentives and organisational strategies that reduce practitioner workload. The most effective recruitment in primary care research requires practitioner involvement. The active participation of primary care practitioners in both the design and conduct of research helps to identify strategies that are congruent with the context in which patient care is delivered. This is reported to be the

Designing effective therapeutic strategies for complex diseases such as cancer and neurodegeneration that involve tissue context-specific interactions among multiple gene products presents a major challenge for precision medicine. Safe and selective pharmacological modulation of individual molecular entities associated with a disease often fails to provide efficacy in the clinic. Thus, development of optimized therapeutic strategies for individual patients with complex diseases requires a more comprehensive, systems-level understanding of disease progression. Quantitative systems pharmacology (QSP) is an approach to drug discovery that integrates computational and experimental methods to understand the molecular pathogenesis of a disease at the systems level more completely. Described here is the chemogenomic component of QSP for the inference of biological pathways involved in the modulation of the disease phenotype. The approach involves testing sets of compounds of diverse mechanisms of action in a disease-relevant phenotypic assay, and using the mechanistic information known for the active compounds, to infer pathways and networks associated with the phenotype. The example used here is for monogenic Huntington's disease (HD), which due to the pleiotropic nature of the mutant phenotype has a complex pathogenesis. The overall approach, however, is applicable to any complex disease.

We assess Massachusetts emergency department (ED) involvement and internal ED constructs within accountable care organization contracts. An online survey was distributed to 70 Massachusetts ED directors. Questions attempted to assess involvement of EDs in accountable care organizations and the structures in place in EDs-from departmental resources to physician incentives-to help achieve accountable care organization goals of decreasing spending and improving quality. Of responding ED directors, 79% reported alignment between the ED and an accountable care organization. Almost all ED groups (88%) reported bearing no financial risk as a result of the accountable care organization contracts in which their organizations participated. Major obstacles to meeting accountable care organization objectives included care coordination challenges (62%) and lack of familiarity with accountable care organization goals (58%). The most common cost-reduction strategies included ED case management (85%) and information technology (61%). Limitations of this study include that information was self-reported by ED directors, a focus limited to Massachusetts, and a survey response rate of 47%. The ED directors perceived that the majority of physicians were not familiar with accountable care organization goals, many challenges remain in coordinating care for patients in the ED, and most EDs have no financial incentives tied to accountable care organizations. EDs in Massachusetts have begun to implement strategies aimed at reducing admissions, utilization, and overall cost, but these strategies are not widespread apart from case management, even in a state with heavy accountable care organization penetration. Our results suggest that Massachusetts EDs still lack clear directives and direct involvement in meeting accountable care organization goals.

Strategy Guideline: HVAC Equipment Sizing

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

Burdick, A.

The heating, ventilation, and air conditioning (HVAC) system is arguably the most complex system installed in a house and is a substantial component of the total house energy use. A right-sized HVAC system will provide the desired occupant comfort and will run efficiently. This Strategy Guideline discusses the information needed to initially select the equipment for a properly designed HVAC system. Right-sizing of an HVAC system involves the selection of equipment and the design of the air distribution system to meet the accurate predicted heating and cooling loads of the house. Right-sizing the HVAC system begins with an accurate understandingmore » of the heating and cooling loads on a space; however, a full HVAC design involves more than just the load estimate calculation - the load calculation is the first step of the iterative HVAC design procedure. This guide describes the equipment selection of a split system air conditioner and furnace for an example house in Chicago, IL as well as a heat pump system for an example house in Orlando, Florida. The required heating and cooling load information for the two example houses was developed in the Department of Energy Building America Strategy Guideline: Accurate Heating and Cooling Load Calculations.« less

Strategies for ensuring global consistency/comparability of water-quality data

USGS Publications Warehouse

Klein, J.M.

1999-01-01

In the past 20 years the water quality of the United States has improved remarkably-the waters are safer for drinking, swimming, and fishing. However, despite many accomplishments, it is still difficult to answer such basic questions as: 'How clean is the water?' and 'How is it changing over time?' These same questions exist on a global scale as well. In order to focus water-data issues in the United States, a national Intergovernmental Task Force on Monitoring Water Quality (ITFM) was initiated for public and private organizations, whereby key elements involved in data collection, analysis, storage, and management could be made consistent and comparable. The ITFM recommended and its members are implementing a nationwide strategy to improve water-quality monitoring, assessment, and reporting activities. The intent of this paper is to suggest that a voluntary effort be initiated to ensure the comparability and utility of hydrological data on a global basis. Consistent, long-term data sets that are comparable are necessary in order to formulate ideas regarding regional and global trends in water quantity and quality. The author recommends that a voluntary effort similar to the ITFM effort be utilized. The strategy proposed would involve voluntary representation from countries and international organizations (e.g. World Health Organization) involved in drinking-water assessments and/or ambient water-quality monitoring. Voluntary partnerships such as this will improve curability to reduce health risks and achieve a better return on public and private investments in monitoring, environmental protection, and natural resource management, and result in a collaborative process that will save millions of dollars.In this work it is suggested that a voluntary effort be initiated to ensure the comparability and utility of hydrological data on a global basis.

2013-03-01

The purpose of the study was to describe male involvement in programmes for preventing mother-tochild transmission (PMTCT) in Sub-Saharan Africa. The study questions guiding this review were: how are male partners involved in PMTCT programmes in Sub-Saharan Africa and what are the strategies for improvement of male involvement? An integrative review was conducted based on the data retrieved from the PubMed MEDLINE database. In all, 18 articles were included in this review. Qualitative content analysis was used as a method of data synthesis. Based on the findings of this review, some studies suggested that men had positive attitudes towards PMTCT programmes. However, also barriers to male involvement were identified. These barriers included negative attitude, lack of resources, fear of human immunodeficiency virus (HIV) test result, marital difficulties, problems with health care services and cultural barriers. Accepting HIV testing was associated with factors related to both wife and husband. Strategies for improving male involvement included ones that focus on men's and their wives' resources (sensitizing men about antenatal care (ANC) and PMTCT, focusing on the conjugal context and couples counselling), the development of health care services (tailoring the services to male needs, taking care of health care staff's resources, developing health care strategies) and the community (educating the community, testing, safer infant feeding). We should highlight the male participation in PMTCT programmes. However, more research is needed in order to evaluate their impact on PMTCT, as well as on broader family health outcomes.

ANN modeling of DNA sequences: new strategies using DNA shape code.

Two new encoding strategies, namely, wedge and twist codes, which are based on the DNA helical parameters, are introduced to represent DNA sequences in artificial neural network (ANN)-based modeling of biological systems. The performance of the new coding strategies has been evaluated by conducting three case studies involving mapping (modeling) and classification applications of ANNs. The proposed coding schemes have been compared rigorously and shown to outperform the existing coding strategies especially in situations wherein limited data are available for building the ANN models.

Strategy selection in cue-based decision making.

PubMed

Bryant, David J

2014-06-01

People can make use of a range of heuristic and rational, compensatory strategies to perform a multiple-cue judgment task. It has been proposed that people are sensitive to the amount of cognitive effort required to employ decision strategies. Experiment 1 employed a dual-task methodology to investigate whether participants' preference for heuristic versus compensatory decision strategies can be altered by increasing the cognitive demands of the task. As indicated by participants' decision times, a secondary task interfered more with the performance of a heuristic than compensatory decision strategy but did not affect the proportions of participants using either type of strategy. A stimulus set effect suggested that the conjunction of cue salience and cue validity might play a determining role in strategy selection. The results of Experiment 2 indicated that when a perceptually salient cue was also the most valid, the majority of participants preferred a single-cue heuristic strategy. Overall, the results contradict the view that heuristics are more likely to be adopted when a task is made more cognitively demanding. It is argued that people employ 2 learning processes during training, one an associative learning process in which cue-outcome associations are developed by sampling multiple cues, and another that involves the sequential examination of single cues to serve as a basis for a single-cue heuristic.

Performance as a function of ability, resources invested, and strategy used.

Botella, Juan; Peña, Daniel; Contreras, María José; Shih, Pei-Chun; Santacreu, José

2009-01-01

Computerized tasks allow a more fine-grained analysis of the strategy deployed in a task designed to map a specific ability than the usual assessment on the basis of only the level of performance. Manipulations expected to impair performance sometimes do not have that effect, probably because the level of performance alone can confound the assessment of the ability level if researchers ignore the strategy used. In a study with 1,872 participants, the authors applied the Spatial Orientation Dynamic Test-Revised (J. Santacreu, 1999) in single and dual task settings, identifying 3 different strategies. Strategy shifts were associated with the level of performance, as more apt individuals were more likely to shift to better strategies. Ignoring the strategies yields counterintuitive results that cannot be explained by simple, direct relations among the constructs involved.

Discovery and partial characterization of a non-LTR retrotransposon that may be associated with abdominal segment deformity disease (ASDD) in the whiteleg shrimp Penaeus (Litopenaeus) vannamei.

Abdominal segment deformity disease (ASDD) of cultivated whiteleg shrimp Penaeus (Litopenaeus) vannamei causes economic loss of approximately 10% in affected specimens because of the unsightliness of distorted abdominal muscles. It is associated with the presence of viral-like particles seen by electron microscopy in the ventral nerve cords of affected shrimp. Thus, shotgun cloning was carried out to seek viral-like sequences in affected shrimp. A new retrovirus-like element of 5052 bp (named abdominal segment deformity element or ASDE) was compiled by shotgun cloning and 3' and 5' RACE using RNA and DNA extracted from ventral nerve cords of ASDD shrimp. ASDE contained 7 putative open reading frames (ORF). One ORF (called the PENS sub-domain), had a deduced amino acid (aa) sequence homologous to the GIY-YIG endonuclease domain of penelope-like retrotransposons while two others were homologous to the reverse transcriptase (RT) and RNaseH domains of the pol gene of non-long terminal repeat (non-LTR) retrotransposons (called the NLRS sub-domain). No single amplicon of 5 kb containing both these elements was obtained by PCR or RT-PCR from ASDD shrimp. Subsequent analysis indicated that PENS and NLRS were not contiguous and that NLRS was a host genetic element. In situ hybridization using a dioxygenin-labeled NLRS probe revealed that NLRS gave positive reactions in abdominal-ganglion neurons of ASDD shrimp but not normal shrimp. Preliminary analysis indicated that long-term use of female broodstock after eyestalk ablation in the hatchery increased the intensity of RT-PCR amplicons for NLRS and also the prevalence of ASDD in mysis 3 offspring of the broodstock. The deformities persist upon further cultivation until shrimp harvest but do not increase in prevalence and do not affect growth or survival. Our results suggested that NLRS is a shrimp genetic element associated with ASDD and that immediate preventative measures could include shorter-term use of broodstock after

User-driven sampling strategies in image exploitation

NASA Astrophysics Data System (ADS)

Harvey, Neal; Porter, Reid

2013-12-01

Visual analytics and interactive machine learning both try to leverage the complementary strengths of humans and machines to solve complex data exploitation tasks. These fields overlap most significantly when training is involved: the visualization or machine learning tool improves over time by exploiting observations of the human-computer interaction. This paper focuses on one aspect of the human-computer interaction that we call user-driven sampling strategies. Unlike relevance feedback and active learning sampling strategies, where the computer selects which data to label at each iteration, we investigate situations where the user selects which data is to be labeled at each iteration. User-driven sampling strategies can emerge in many visual analytics applications but they have not been fully developed in machine learning. User-driven sampling strategies suggest new theoretical and practical research questions for both visualization science and machine learning. In this paper we identify and quantify the potential benefits of these strategies in a practical image analysis application. We find user-driven sampling strategies can sometimes provide significant performance gains by steering tools towards local minima that have lower error than tools trained with all of the data. In preliminary experiments we find these performance gains are particularly pronounced when the user is experienced with the tool and application domain.

Regulation of Romantic Love Feelings: Preconceptions, Strategies, and Feasibility

Love feelings can be more intense than desired (e.g., after a break-up) or less intense than desired (e.g., in long-term relationships). If only we could control our love feelings! We present the concept of explicit love regulation, which we define as the use of behavioral and cognitive strategies to change the intensity of current feelings of romantic love. We present the first two studies on preconceptions about, strategies for, and the feasibility of love regulation. Questionnaire responses showed that people perceive love feelings as somewhat uncontrollable. Still, in four open questions people reported to use strategies such as cognitive reappraisal, distraction, avoidance, and undertaking (new) activities to cope with break-ups, to maintain long-term relationships, and to regulate love feelings. Instructed up-regulation of love using reappraisal increased subjective feelings of attachment, while love down-regulation decreased subjective feelings of infatuation and attachment. We used the late positive potential (LPP) amplitude as an objective index of regulation success. Instructed love up-regulation enhanced the LPP between 300–400 ms in participants who were involved in a relationship and in participants who had recently experienced a romantic break-up, while love down-regulation reduced the LPP between 700–3000 ms in participants who were involved in a relationship. These findings corroborate the self-reported feasibility of love regulation, although they are complicated by the finding that love up-regulation also reduced the LPP between 700–3000 ms in participants who were involved in a relationship. To conclude, although people have the preconception that love feelings are uncontrollable, we show for the first time that intentional regulation of love feelings using reappraisal, and perhaps other strategies, is feasible. Love regulation will benefit individuals and society because it could enhance positive effects and reduce negative effects of

Siderophore-drug complexes: potential medicinal applications of the 'Trojan horse' strategy.

2014-09-01

The ability of bacteria to develop resistance to antimicrobial agents poses problems in the treatment of numerous bacterial infections. One method to circumvent permeability-mediated drug resistance involves the employment of the 'Trojan horse' strategy. The Trojan horse concept involves the use of bacterial iron uptake systems to enter and kill bacteria. The siderophore-drug complex is recognized by specific siderophore receptors and is then actively transported across the outer membrane. The recently identified benefits of this strategy have led to the synthesis of a series of siderophore-based antibiotics. Several studies have shown that siderophore-drug conjugates make it possible to design antibiotics with improved cell transport and reduce the frequency of resistance mutants. Growing interest in siderophore-drug conjugates for the treatment of human diseases including iron overload, cancer, and malaria has driven the search for new siderophore-drug complexes. This strategy may have special importance for the development of iron oxide nanoparticle-based therapeutics. Copyright © 2014 Elsevier Ltd. All rights reserved.

The influence of training and experience on memory strategy.

2015-07-01

This paper investigates whether, and if so how much, prior training and experience overwrite the influence of the constraints of the task environment on strategy deployment. This evidence is relevant to the theory of soft constraints that focuses on the role of constraints in the task environment (Gray, Simms, Fu, & Schoelles, Psychological Review, 113: 461-482, 2006). The theory explains how an increase in the cost of accessing information induces a more memory-based strategy involving more encoding and planning. Experiments 1 and 3 adopt a traditional training and transfer design using the Blocks World Task in which participants were exposed to training trials involving a 2.5-s delay in accessing goal-state information before encountering transfer trials in which there was no access delay. The effect of prior training was assessed by the degree of memory-based strategy adopted in the transfer trials. Training with an access delay had a substantial carry-over effect and increased the subsequent degree of memory-based strategy adopted in the transfer environment. However, such effects do not necessarily occur if goal-state access cost in training is less costly than in transfer trials (Experiment 2). Experiment 4 used a fine-grained intra-trial design to examine the effect of experiencing access cost on one, two, or three occasions within the same trial and found that such experience on two consecutive occasions was sufficient to induce a more memory-based strategy. This paper establishes some effects of training that are relevant to the soft constraints theory and also discusses practical implications.

To review published examples of public involvement in research design, to synthesise the contributions made by members of the public, as well as the identified barriers, tensions and facilitating strategies. Systematic literature search and narrative review. Seven papers were identified covering the following topics: breast-feeding, antiretroviral and nutrition interventions; paediatric resuscitation; exercise and cognitive behavioural therapy; hormone replacement therapy and breast cancer; stroke; and parents' experiences of having a pre-term baby. Six papers reported public involvement in the development of a clinical trial, while one reported public involvement in the development of a mixed methods study. Group meetings were the most common method of public involvement. Contributions that members of the public made to research design were: review of consent procedures and patient information sheets; outcome suggestions; review of acceptability of data collection procedures; and recommendations on the timing of potential participants into the study and the timing of follow-up. Numerous barriers, tensions and facilitating strategies were identified. The issues raised here should assist researchers in developing research proposals with members of the public. Substantive and methodological directions for further research on the impact of public involvement in research design are set out. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

The best strategies to screen postmenopausal women for osteoporosis are not clear. To identify the cost-effectiveness of various screening strategies. Individual-level state-transition cost-effectiveness model. Published literature. U.S. women aged 55 years or older. Lifetime. Payer. Screening strategies composed of alternative tests (central dual-energy x-ray absorptiometry [DXA], calcaneal quantitative ultrasonography [QUS], and the Simple Calculated Osteoporosis Risk Estimation [SCORE] tool) initiation ages, treatment thresholds, and rescreening intervals. Oral bisphosphonate treatment was assumed, with a base-case adherence rate of 50% and a 5-year on/off treatment pattern. Incremental cost-effectiveness ratios (2010 U.S. dollars per quality-adjusted life-year [QALY] gained). At all evaluated ages, screening was superior to not screening. In general, quality-adjusted life-days gained with screening tended to increase with age. At all initiation ages, the best strategy with an incremental cost-effectiveness ratio (ICER) of less than $50,000 per QALY was DXA screening with a T-score threshold of -2.5 or less for treatment and with follow-up screening every 5 years. Across screening initiation ages, the best strategy with an ICER less than $50,000 per QALY was initiation of screening at age 55 years by using DXA -2.5 with rescreening every 5 years. The best strategy with an ICER less than $100,000 per QALY was initiation of screening at age 55 years by using DXA with a T-score threshold of -2.0 or less for treatment and then rescreening every 10 years. No other strategy that involved treatment of women with osteopenia had an ICER less than $100,000 per QALY. Many other strategies, including strategies with SCORE or QUS prescreening, were also cost-effective, and in general the differences in effectiveness and costs between evaluated strategies was small. Probabilistic sensitivity analysis did not reveal a consistently superior strategy. Data were primarily from

Health policy requires consumer involvement in services, research and education but little is known about how consumers are being involved in healthcare education, the effect on learning and practice, nor how involvement initiatives are being evaluated. To describe methods of involving consumers in healthcare education, discuss ways in which initiatives have been evaluated, and identify areas for development in education, practice and research. All papers reporting specific initiatives involving consumers in health care worker training and education were included. Viewpoint articles and studies of consumers training consumers were excluded. Cinahl, Medline, Assia, PsycINFO, British Nursing Index, Social Science Citation Index, citations from reference lists, relevant websites and personal communication with key people known to be working in this area. A narrative approach was taken with categorisation of data to reflect objectives of selected studies; method of involvement; process issues and evaluation. Thirty-eight papers were included; most provide small-scale qualitative studies of mental health service users and focus on process rather than outcome. Various methods of involvement are described and consumers consistently prioritise the need for training in interpersonal skills over 'technical' skills. There is little research into organisational strategies and no studies investigate the effect of consumer involvement on practice. Two studies indicated that students exposed to consumer involvement demonstrate more empathic understanding and better communication skills. There is tentative evidence that consumer involvement in training enhances workers' skills in the manner prioritised by consumers. However, if consumer involvement in training and education is to facilitate services that reflect the priorities of the people using them, it must be developed in partnership with service providers; further research is needed to explore the impact of consumer

Genetic adaptation to captivity can occur in a single generation

Captive breeding programs are widely used for the conservation and restoration of threatened and endangered species. Nevertheless, captive-born individuals frequently have reduced fitness when reintroduced into the wild. The mechanism for these fitness declines has remained elusive, but hypotheses include environmental effects of captive rearing, inbreeding among close relatives, relaxed natural selection, and unintentional domestication selection (adaptation to captivity). We used a multigenerational pedigree analysis to demonstrate that domestication selection can explain the precipitous decline in fitness observed in hatchery steelhead released into the Hood River in Oregon. After returning from the ocean, wild-born and first-generation hatchery fish were used as broodstock in the hatchery, and their offspring were released into the wild as smolts. First-generation hatchery fish had nearly double the lifetime reproductive success (measured as the number of returning adult offspring) when spawned in captivity compared with wild fish spawned under identical conditions, which is a clear demonstration of adaptation to captivity. We also documented a tradeoff among the wild-born broodstock: Those with the greatest fitness in a captive environment produced offspring that performed the worst in the wild. Specifically, captive-born individuals with five (the median) or more returning siblings (i.e., offspring of successful broodstock) averaged 0.62 returning offspring in the wild, whereas captive-born individuals with less than five siblings averaged 2.05 returning offspring in the wild. These results demonstrate that a single generation in captivity can result in a substantial response to selection on traits that are beneficial in captivity but severely maladaptive in the wild.

Effective size of a wild salmonid population is greatly reduced by hatchery supplementation

2012-01-01

Many declining and commercially important populations are supplemented with captive-born individuals that are intentionally released into the wild. These supplementation programs often create large numbers of offspring from relatively few breeding adults, which can have substantial population-level effects. We examined the genetic effects of supplementation on a wild population of steelhead (Oncorhynchus mykiss) from the Hood River, Oregon, by matching 12 run-years of hatchery steelhead back to their broodstock parents. We show that the effective number of breeders producing the hatchery fish (broodstock parents; Nb) was quite small (harmonic mean Nb=25 fish per brood-year vs 373 for wild fish), and was exacerbated by a high variance in broodstock reproductive success among individuals within years. The low Nb caused hatchery fish to have decreased allelic richness, increased average relatedness, more loci in linkage disequilibrium and substantial levels of genetic drift in comparison with their wild-born counterparts. We also documented a substantial Ryman–Laikre effect whereby the additional hatchery fish doubled the total number of adult fish on the spawning grounds each year, but cut the effective population size of the total population (wild and hatchery fish combined) by nearly two-thirds. We further demonstrate that the Ryman–Laikre effect is most severe in this population when (1) >10% of fish allowed onto spawning grounds are from hatcheries and (2) the hatchery fish have high reproductive success in the wild. These results emphasize the trade-offs that arise when supplementation programs attempt to balance disparate goals (increasing production while maintaining genetic diversity and fitness).

Increases in Drug and Opioid-Involved Overdose Deaths - United States, 2010-2015.

PubMed

Rudd, Rose A; Seth, Puja; David, Felicita; Scholl, Lawrence

2016-12-30

The U.S. opioid epidemic is continuing, and drug overdose deaths nearly tripled during 1999-2014. Among 47,055 drug overdose deaths that occurred in 2014 in the United States, 28,647 (60.9%) involved an opioid (1). Illicit opioids are contributing to the increase in opioid overdose deaths (2,3). In an effort to target prevention strategies to address the rapidly changing epidemic, CDC examined overall drug overdose death rates during 2010-2015 and opioid overdose death rates during 2014-2015 by subcategories (natural/semisynthetic opioids, methadone, heroin, and synthetic opioids other than methadone).* Rates were stratified by demographics, region, and by 28 states with high quality reporting on death certificates of specific drugs involved in overdose deaths. During 2015, drug overdoses accounted for 52,404 U.S. deaths, including 33,091 (63.1%) that involved an opioid. There has been progress in preventing methadone deaths, and death rates declined by 9.1%. However, rates of deaths involving other opioids, specifically heroin and synthetic opioids other than methadone (likely driven primarily by illicitly manufactured fentanyl) (2,3), increased sharply overall and across many states. A multifaceted, collaborative public health and law enforcement approach is urgently needed. Response efforts include implementing the CDC Guideline for Prescribing Opioids for Chronic Pain (4), improving access to and use of prescription drug monitoring programs, enhancing naloxone distribution and other harm reduction approaches, increasing opioid use disorder treatment capacity, improving linkage into treatment, and supporting law enforcement strategies to reduce the illicit opioid supply.

Being useful: achieving indigenous youth involvement in a community-based participatory research project in Alaska

Ford, Tara; Rasmus, Stacy; Allen, James

2012-01-01

Objectives To report on a participatory research process in southwest Alaska focusing on youth involvement as a means to facilitate health promotion. We propose youth-guided community-based participatory research (CBPR) as way to involve young people in health promotion and prevention strategizing as part of translational science practice at the community-level. Study design We utilized a CBPR approach that allowed youth to contribute at all stages. Methods Implementation of the CBPR approach involved the advancement of three key strategies including: (a) the local steering committee made up of youth, tribal leaders, and elders, (b) youth-researcher partnerships, and (c) youth action-groups to translate findings. Results The addition of a local youth-action and translation group to the CBPR process in the southwest Alaska site represents an innovative strategy for disseminating findings to youth from a research project that focuses on youth resilience and wellbeing. This strategy drew from two community-based action activities: (a) being useful by helping elders and (b) being proud of our village. Conclusions In our study, youth informed the research process at every stage, but most significantly youth guided the translation and application of the research findings at the community level. Findings from the research project were translated by youth into serviceable action in the community where they live. The research created an experience for youth to spend time engaged in activities that, from their perspectives, are important and contribute to their wellbeing and healthy living. Youth-guided CBPR meant involving youth in the process of not only understanding the research process but living through it as well. PMID:22584510

Co-action provides rational basis for the evolutionary success of Pavlovian strategies

NASA Astrophysics Data System (ADS)

Sasidevan, V.; Sinha, Sitabhra

2016-08-01

Strategies incorporating direct reciprocity, e.g., Tit-for-Tat and Pavlov, have been shown to be successful for playing the Iterated Prisoners Dilemma (IPD), a paradigmatic problem for studying the evolution of cooperation among non-kin individuals. However it is an open question whether such reciprocal strategies can emerge as the rational outcome of repeated interactions between selfish agents. Here we show that adopting a co-action perspective, which takes into account the symmetry between agents - a relevant consideration in biological and social contexts - naturally leads to such a strategy. For a 2-player IPD, we show that the co-action solution corresponds to the Pavlov strategy, thereby providing a rational basis for it. For an IPD involving many players, an instance of the Public Goods game where cooperation is generally considered to be harder to achieve, we show that the cooperators always outnumber defectors in the co-action equilibrium. This can be seen as a generalization of Pavlov to contests involving many players. In general, repeated interactions allow rational agents to become aware of the inherent symmetry of their situation, enabling them to achieve robust cooperation through co-action strategies - which, in the case of IPD, is a reciprocal Pavlovian one.

Analysis of pilot control strategy

Heffley, R. K.; Hanson, G. D.; Jewell, W. F.; Clement, W. F.

1983-01-01

Methods for nonintrusive identification of pilot control strategy and task execution dynamics are presented along with examples based on flight data. The specific analysis technique is Nonintrusive Parameter Identification Procedure (NIPIP), which is described in a companion user's guide (NASA CR-170398). Quantification of pilot control strategy and task execution dynamics is discussed in general terms followed by a more detailed description of how NIPIP can be applied. The examples are based on flight data obtained from the NASA F-8 digital fly by wire airplane. These examples involve various piloting tasks and control axes as well as a demonstration of how the dynamics of the aircraft itself are identified using NIPIP. Application of NIPIP to the AFTI/F-16 flight test program is discussed. Recommendations are made for flight test applications in general and refinement of NIPIP to include interactive computer graphics.

Enhancing marketing recruitment strategies: administrator tenure and nursing expenditures.

PubMed

Gunby, Norris White

2005-01-01

When recruiting nurses, long-term care facilities require an ability to identify salient organizational characteristics that are attractive to potential nursing services candidates vis-à-vis their competitors. The findings of this study suggest that information on administrative tenure can be utilized to attract applicants by appealing to criteria within their high-involvement job search activities. High-involvement applicants proactively seek recruitment content that provides essential job attributes that match their needs and skills and are more apt to be a higher quality candidate. Based upon the study's findings, managers are offered marketing strategy recommendations for tailoring recruiting messages that appeal to high-involvement job seekers.

User-Driven Sampling Strategies in Image Exploitation

DOE PAGES

Harvey, Neal R.; Porter, Reid B.

2013-12-23

Visual analytics and interactive machine learning both try to leverage the complementary strengths of humans and machines to solve complex data exploitation tasks. These fields overlap most significantly when training is involved: the visualization or machine learning tool improves over time by exploiting observations of the human-computer interaction. This paper focuses on one aspect of the human-computer interaction that we call user-driven sampling strategies. Unlike relevance feedback and active learning sampling strategies, where the computer selects which data to label at each iteration, we investigate situations where the user selects which data is to be labeled at each iteration. User-drivenmore » sampling strategies can emerge in many visual analytics applications but they have not been fully developed in machine learning. We discovered that in user-driven sampling strategies suggest new theoretical and practical research questions for both visualization science and machine learning. In this paper we identify and quantify the potential benefits of these strategies in a practical image analysis application. We find user-driven sampling strategies can sometimes provide significant performance gains by steering tools towards local minima that have lower error than tools trained with all of the data. Furthermore, in preliminary experiments we find these performance gains are particularly pronounced when the user is experienced with the tool and application domain.« less

Role of the neostriatal dopaminergic activity in sequencing and selecting behavioural strategies: facilitation of processes involved in selecting the best strategy in a stressful situation.

PubMed

Cools, A R

1980-10-01

The purpose of this study was to detect the behavioural effect of drug-induced changes in the neostriatal dopaminergic activity upon the degree of intrinsic (self-generated) and extrinsic (externally produced) constraints on the selection of behavioural patterns in rats. Both systemic and neostriatal injections of extremely low doses of apomorphine and haloperidol were used to change the neostriatal dopaminergic activity. Behavioural changes were observed in (a) an open-field test, (b) a so-called 'swimming without escape' test, (c) a so-called 'swimming with escape' test, and (d) a test to detect deficiencies in sensory, motor and sensorimotor capacities required to perform both swimming tests. Evidence is found that the neostriatum, especially the neostriatal, dopaminergic activity determines the animal's ability to select the best strategy in a stressful situation by modifying the process of switching strategies under pressure of factors intrinsic to the organism: neither sensory neglect nor inability to initiate voluntary movements underlay the observed phenomena. It is suggested that the neostriatum determines the individual flexibility to cope with available sensory information.

Molecular Imaging: Current Status and Emerging Strategies

2011-01-01

In vivo molecular imaging has a great potential to impact medicine by detecting diseases in early stages (screening), identifying extent of disease, selecting disease- and patient-specific therapeutic treatment (personalized medicine), applying a directed or targeted therapy, and measuring molecular-specific effects of treatment. Current clinical molecular imaging approaches primarily use PET- or SPECT-based techniques. In ongoing preclinical research novel molecular targets of different diseases are identified and, sophisticated and multifunctional contrast agents for imaging these molecular targets are developed along with new technologies and instrumentation for multimodality molecular imaging. Contrast-enhanced molecular ultrasound with molecularly-targeted contrast microbubbles is explored as a clinically translatable molecular imaging strategy for screening, diagnosing, and monitoring diseases at the molecular level. Optical imaging with fluorescent molecular probes and ultrasound imaging with molecularly-targeted microbubbles are attractive strategies since they provide real-time imaging, are relatively inexpensive, produce images with high spatial resolution, and do not involve exposure to ionizing irradiation. Raman spectroscopy/microscopy has emerged as a molecular optical imaging strategy for ultrasensitive detection of multiple biomolecules/biochemicals with both in vivo and ex vivo versatility. Photoacoustic imaging is a hybrid of optical and ultrasound modalities involving optically-excitable molecularly-targeted contrast agents and quantitative detection of resulting oscillatory contrast agent movement with ultrasound. Current preclinical findings and advances in instrumentation such as endoscopes and microcatheters suggest that these molecular imaging modalities have numerous clinical applications and will be translated into clinical use in the near future.

Deep--deeper--deepest? Encoding strategies and the recognition of human faces.

PubMed

Sporer, S L

1991-03-01

Various encoding strategies that supposedly promote deeper processing of human faces (e.g., character judgments) have led to better recognition than more shallow processing tasks (judging the width of the nose). However, does deeper processing actually lead to an improvement in recognition, or, conversely, does shallow processing lead to a deterioration in performance when compared with naturally employed encoding strategies? Three experiments systematically compared a total of 8 different encoding strategies manipulating depth of processing, amount of elaboration, and self-generation of judgmental categories. All strategies that required a scanning of the whole face were basically equivalent but no better than natural strategy controls. The consistently worst groups were the ones that rated faces along preselected physical dimensions. This can be explained by subjects' lesser task involvement as revealed by manipulation checks.

Service user and caregiver involvement in mental health system strengthening in low- and middle-income countries: a cross-country qualitative study.

The aims of this paper are to: (i) explore the experiences of involvement of mental health service users, their caregivers, mental health centre heads and policy makers in mental health system strengthening in three low- and middle-income countries (LMICs) (Ethiopia, Nepal and Nigeria); (ii) analyse the potential benefits and barriers of such involvement; and (iii) identify strategies required to achieve greater service user and caregiver participation. A cross-country qualitative study was conducted, interviewing 83 stakeholders of mental health services. Our analysis showed that service user and caregiver involvement in the health system strengthening process was an alien concept for most participants. They reported very limited access to direct participation. Stigma and poverty were described as the main barriers for involvement. Several strategies were identified by participants to overcome existing hurdles to facilitate service user and caregiver involvement in the mental health system strengthening process, such as support to access treatment, mental health promotion and empowerment of service users. This study suggests that capacity building for service users, and strengthening of user groups would equip them to contribute meaningfully to policy development from informed perspectives. Involvement of service users and their caregivers in mental health decision-making is still in its infancy in LMICs. Effective strategies are required to overcome existing barriers, for example making funding more widely available for Ph.D. studies in participatory research with service users and caregivers to develop, implement and evaluate approaches to involvement that are locally and culturally acceptable in LMICs.

This study aims to examine the rates of self-reported contacts with the criminal justice system among homeless adults with mental illness, to identify the characteristics of participants who have had contacts with the criminal justice system, to report the dimensional structure of criminal justice system involvement in this sample, and to identify typologies of justice-involved participants. Self-report data on criminal justice system involvement of 2221 adults participating in a Canadian Housing First trial were analyzed using multiple correspondence and cluster analysis. Almost half of the participants had at least one contact with the criminal justice system in the 6months prior to study enrollment. Factors associated with justice involvement included age, gender, ethnic background, diagnosis, substance misuse, impulse control, compliance, victimization, service use, and duration of homelessness. A typology of criminal justice involvement was developed. Seven criminal justice system involvement profiles emerged; substance use and impulse control distinguished the clusters, whereas demographic and contextual variables did not. The large number of profiles indicates the need for a diverse and flexible range of interventions that could be integrated within or in addition to current support of housing services, including integrated substance use and mental health interventions, risk management strategies, and trauma-oriented services.

Arsenic Hyperaccumulation Strategies: An Overview

PubMed Central

Souri, Zahra; Karimi, Naser; Sandalio, Luisa M.

2017-01-01

Arsenic (As) pollution, which is on the increase around the world, poses a growing threat to the environment. Phytoremediation, an important green technology, uses different strategies, including As uptake, transport, translocation, and detoxification, to remediate this metalloid. Arsenic hyperaccumulator plants have developed various strategies to accumulate and tolerate high concentrations of As. In these plants, the formation of AsIII complexes with GSH and phytochelatins and their transport into root and shoot vacuoles constitute important mechanisms for coping with As stress. The oxidative stress induced by reactive oxygen species (ROS) production is one of the principal toxic effects of As; moreover, the strong antioxidative defenses in hyperaccumulator plants could constitute an important As detoxification strategy. On the other hand, nitric oxide activates antioxidant enzyme and phytochelatins biosynthesis which enhances As stress tolerance in plants. Although several studies have focused on transcription, metabolomics, and proteomic changes in plants induced by As, the mechanisms involved in As transport, translocation, and detoxification in hyperaccumulator plants need to be studied in greater depth. This review updates recent progress made in the study of As uptake, translocation, chelation, and detoxification in As hyperaccumulator plants. PMID:28770198

Service user and caregiver involvement has become an increasingly common strategy to enhance mental health outcomes, and has been incorporated in the mental healthpolicies of many developed nations. However, this practice is non-existent or fragmented in low and middle income countries (LMICs). Instances of service user and caregiver involvement have been rising slowly in a few LMICs, but are rarely described in the literature. Very little is known about the context of user and caregiver participation in mental health system strengthening processes in a low-income, disaster- and conflict-affected state such as Nepal. This study explores (a) the extent and experiences of service user and caregiver involvement in policy making, service planning, monitoring, and research in Nepal; (b) perceived barriers to such involvement; and (c) possible strategies to overcome barriers. Key Informant Interviews (n = 24) were conducted with service users and caregivers who were either affiliated to a mental health organization or receiving menta health care integrated within primary care. Purposive sampling was employed. Data collection was carried out in 2014 in Chitwan and Kathmandu districts of Nepal. Data analysis was carried out in NVivo10 using a framework approach. The involvement of service users affiliated to mental health organizations in policy development was reported to be 'tokenistic'. Involvement of caregivers was non-existent. Perceived barriers to greater involvement included lack of awareness, stigma and discrimination, poor economic conditions, the centralized health system, and lack of strong leadership and unity among user organizations. Increased focus on reducing public as well as self-stigma, improved policy frameworks and initiatives, and decentralization of care are some strategies that may facilitate service user and caregiver involvement. The study highlighted need for user and caregiver networks free from competing interests and priorities. Improved

1987-01-01

A simple strategy for the attitude control and arm coordination of a maneuverable space robot with dual arms is proposed. The basic task for the robot consists of the placement of marked rigid solid objects with specified pairs of gripping points and a specified direction of approach for gripping. The strategy consists of three phases each of which involves only elementary rotational and translational collision-free maneuvers of the robot body. Control laws for these elementary maneuvers are derived by using a body-referenced dynamic model of the dual-arm robot.

Metabolic disorders are a group of disorders, due to the disruption of the normal metabolic process at a cellular level. Diabetes Mellitus and Tyrosinaemia are the majorly reported metabolic disorders. Among them, Diabetes Mellitus is a one of the leading metabolic syndrome, affecting 5 to 7 % of the population worldwide and mainly characterised by elevated levels of glucose and is associated with two types of physiological event disturbances such as impaired insulin secretion and insulin resistance. Up to now, various treatment strategies are like insulin, alphaglucosidase inhibitors, biguanides, incretins were being followed. Concurrently, various novel therapeutic strategies are required to advance the therapy of Diabetes mellitus. For the last few decades, there has been an extensive research in understanding the metabolic pathways involved in Diabetes Mellitus at the cellular level and having the profound knowledge on cell-growth, cell-cycle, and apoptosis at a molecular level provides new targets for the treatment of Diabetes Mellitus. Receptor signalling has been involved in these mechanisms, to translate the information coming from outside. To understand the various receptors involved in these pathways, we must have a sound knowledge on receptors and ligands involved in it. This review mainly summarises the receptors and ligands which are involved the Diabetes Mellitus. Finally, researchers have to develop the alternative chemical moieties that retain their affinity to receptors and efficacy. Diabetes Mellitus being a metabolic disorder due to the glucose surfeit, demands the need for regular exercise along with dietary changes.

The role of intelligence and feedback in children's strategy competence.

Luwel, Koen; Foustana, Ageliki; Papadatos, Yiannis; Verschaffel, Lieven

2011-01-01

A test-intervention-test study was conducted investigating the role of intelligence on four parameters of strategy competence in the context of a numerosity judgment task. Moreover, the effectiveness of two feedback types on these four parameters was tested. In the two test sessions, the choice/no-choice method was used to assess the strategy repertoire, frequency, efficiency, and adaptivity of a group of low-, average-, and high-intelligence children. During the intervention, half of the participants from each intelligence group were given outcome feedback (OFB), whereas the other half received strategy feedback (SFB). The pretest data showed large differences among the three intelligence groups on all four strategy parameters. These differences had disappeared at the posttest due to a particularly strong improvement on all strategy parameters in the low-intelligence group. Furthermore, it was found that SFB was more beneficial than OFB for all parameters involving strategy selection. These results indicate that intelligence plays an important role in children's strategy use and suggest that strategy feedback can be a powerful instructional tool, especially for low-intelligence children.

Lund, Marianne N; Ray, Colin A

2017-06-14

Maillard reactions lead to changes in food color, organoleptic properties, protein functionality, and protein digestibility. Numerous different strategies for controlling Maillard reactions in foods have been attempted during the past decades. In this paper, recent advances in strategies for controlling the Maillard reaction and subsequent downstream reaction products in food systems are critically reviewed. The underlying mechanisms at play are presented, strengths and weaknesses of each strategy are discussed, and reasonable reaction mechanisms are proposed to reinforce the evaluations. The review includes strategies involving addition of functional ingredients, such as plant polyphenols and vitamins, as well as enzymes. The resulting trapping or modification of Maillard targets, reactive intermediates, and advanced glycation endproducts (AGEs) are presented with their potential unwanted side effects. Finally, recent advances in processing for control of Maillard reactions are discussed.

The science of formulation involving cosmetic ingredients has always been a challenge since the release of active components greatly depends upon the carrier system involved and the selectivity of skin barrier. The principle obstacle of the skin resides in the epidermis and it's hard for many active components to cross it. The formulation related factors like size of particles, viscosity and lipophilicity of the components also play an important role in permeation of the dermal composition. Though widely used; conventional creams and gels still struggle in terms of success. This work focuses on nano based formulation strategies for successful delivery of cosmetic agents. Novel strategies like nanoemulsion, nanogels, liposomes, aquasomes, niosomes, dendrimers and fullerenes have paved way for successful delivery of dermal formulations to desire depths in the skin. © Georg Thieme Verlag KG Stuttgart · New York.

Different strategies in solving series completion inductive reasoning problems: an fMRI and computational study.

Liang, Peipeng; Jia, Xiuqin; Taatgen, Niels A; Zhong, Ning; Li, Kuncheng

2014-08-01

Neural correlate of human inductive reasoning process is still unclear. Number series and letter series completion are two typical inductive reasoning tasks, and with a common core component of rule induction. Previous studies have demonstrated that different strategies are adopted in number series and letter series completion tasks; even the underlying rules are identical. In the present study, we examined cortical activation as a function of two different reasoning strategies for solving series completion tasks. The retrieval strategy, used in number series completion tasks, involves direct retrieving of arithmetic knowledge to get the relations between items. The procedural strategy, used in letter series completion tasks, requires counting a certain number of times to detect the relations linking two items. The two strategies require essentially the equivalent cognitive processes, but have different working memory demands (the procedural strategy incurs greater demands). The procedural strategy produced significant greater activity in areas involved in memory retrieval (dorsolateral prefrontal cortex, DLPFC) and mental representation/maintenance (posterior parietal cortex, PPC). An ACT-R model of the tasks successfully predicted behavioral performance and BOLD responses. The present findings support a general-purpose dual-process theory of inductive reasoning regarding the cognitive architecture. Copyright © 2014 Elsevier B.V. All rights reserved.

The role of customers in green supply chain management needs to be identified and recognized as an important research area. This paper is an attempt to explore the involvement aspect of customers towards greening of the supply chain (SC). An empirical research approach has been used to collect primary data to rank different variables for effective customer involvement in green concept implementation in SC. An interpretive structural-based model has been presented, and variables have been classified using matrice d' impacts croises- multiplication appliqué a un classement analysis. Contextual relationships among variables have been established using experts' opinions. The research may help practicing managers to understand the interaction among variables affecting customer involvement. Further, this understanding may be helpful in framing the policies and strategies to green SC. Analyzing interaction among variables for effective customer involvement in greening SC to develop the structural model in the Indian perspective is an effort towards promoting environment consciousness.

Dealing with one's emotions is a core skill in everyday life. Effective cognitive control strategies have been shown to be neurobiologically represented in prefrontal structures regulating limbic regions. In addition to cognitive strategies, mindfulness-associated methods are increasingly applied in psychotherapy. We compared the neurobiological mechanisms of these two strategies, i.e. cognitive reappraisal and mindfulness, during both the cued expectation and perception of negative and potentially negative emotional pictures. Fifty-three healthy participants were examined with functional magnetic resonance imaging (47 participants included in analysis). Twenty-four subjects applied mindfulness, 23 used cognitive reappraisal. On the neurofunctional level, both strategies were associated with comparable activity of the medial prefrontal cortex and the amygdala. When expecting negative versus neutral stimuli, the mindfulness group showed stronger activations in ventro- and dorsolateral prefrontal cortex, supramarginal gyrus as well as in the left insula. During the perception of negative versus neutral stimuli, the two groups only differed in an increased activity in the caudate in the cognitive group. Altogether, both strategies recruited overlapping brain regions known to be involved in emotion regulation. This result suggests that common neural circuits are involved in the emotion regulation by mindfulness-based and cognitive reappraisal strategies. Identifying differential activations being associated with the two strategies in this study might be one step towards a better understanding of differential mechanisms of change underlying frequently used psychotherapeutic interventions.

It's all in the delivery! An analysis of instructional strategies from effective health education curricula.

This study explores the relationship between instructional strategies and effective health education curricula. A content analysis of 10 health education curricula was conducted to determine if they include common instructional strategies for actively engaging students in acquisition of health skills. To be included, the curricula had to (1) be research-based and proven via empirical testing to positively influence the health behaviors and (2) address 1 of Centers for Disease Control and Prevention's 6 priority health risk behaviors. Content analysis revealed 5 active learning strategies incorporated to involve students in acquiring health skills. Role play, group cooperation, and small group discussion were found in all 10 curricula. To a lesser extent, interactive technology and team games were also included. When combined with previous research regarding the characteristics of effective teachers, it becomes clear that effective health education is delivered by teachers who employ a wide repertoire of active learning strategies while devoting substantial instructional time to those specific strategies that involve students in skills practice. © 2011, American School Health Association.

Enhanced visual memory during hypnosis as mediated by hypnotic responsiveness and cognitive strategies.

Crawford, H J; Allen, S N

1983-12-01

To investigate the hypothesis that hypnosis has an enhancing effect on imagery processing, as mediated by hypnotic responsiveness and cognitive strategies, four experiments compared performance of low and high, or low, medium, and high, hypnotically responsive subjects in waking and hypnosis conditions on a successive visual memory discrimination task that required detecting differences between successively presented picture pairs in which one member of the pair was slightly altered. Consistently, hypnotically responsive individuals showed enhanced performance during hypnosis, whereas nonresponsive ones did not. Hypnotic responsiveness correlated .52 (p less than .001) with enhanced performance during hypnosis, but it was uncorrelated with waking performance (Experiment 3). Reaction time was not affected by hypnosis, although high hypnotizables were faster than lows in their responses (Experiments 1 and 2). Subjects reported enhanced imagery vividness on the self-report Vividness of Visual Imagery Questionnaire during hypnosis. The differential effect between lows and highs was in the anticipated direction but not significant (Experiments 1 and 2). As anticipated, hypnosis had no significant effect on a discrimination task that required determining whether there were differences between pairs of simultaneously presented pictures. Two cognitive strategies that appeared to mediate visual memory performance were reported: (a) detail strategy, which involved the memorization and rehearsal of individual details for memory, and (b) holistic strategy, which involved looking at and remembering the whole picture with accompanying imagery. Both lows and highs reported similar predominantly detail-oriented strategies during waking; only highs shifted to a significantly more holistic strategy during hypnosis. These findings suggest that high hypnotizables have a greater capacity for cognitive flexibility (Batting, 1979) than do lows. Results are discussed in terms of several

HIV continues to be a major concern among MSM, yet Black MSM have not been enrolled in HIV research studies in proportionate numbers to White MSM. We developed an HIV prevention research brand strategy for MSM. Questionnaires and focus groups were conducted with 54 participants. Descriptive statistics and chi-square analyses were performed and qualitative data were transcribed and content analyzed to identify common themes. Formative research results indicated that younger Black MSM (18-29 years) were less likely to think about joining prevention studies compared to older (≥30 years) Black MSM ( x 2 = 5.92, P = 0.015). Qualitative and quantitative results indicate four prominent themes related to brand development: (1) communication sources (message deliverer), (2) message (impact of public health messaging on perceptions of HIV research), (3) intended audience (underlying issues that influence personal relevance of HIV research), and (4) communication channels (reaching intended audiences). The findings highlight the importance of behavioral communication translational research to effectively engage hard-to-reach populations. Despite reservations, MSM in our formative study expressed a need for active involvement and greater education to facilitate their engagement in HIV prevention research. Thus, the brand concept of "InvolveMENt" emerged.

Cutrer, William B; Sullivan, William M; Fleming, Amy E

2013-10-01

Clinical reasoning serves as a crucial skill for all physicians regardless of their area of expertise. Helping trainees develop effective and appropriate clinical reasoning abilities is a central aim of medical education. Teaching clinical reasoning however can be a very difficult challenge for practicing physicians. Better understanding of the different cognitive processes involved in physician clinical reasoning provides a foundation from which to guide learner development of effective reasoning skills, while pairing assessment of learner reasoning abilities with understanding of different improvement strategies offers the opportunity to maximize educational efforts for learners. Clinical reasoning errors often can occur as a result of one of four problems in trainees as well as practicing physicians; inadequate knowledge, faulty data gathering, faulty data processing, or faulty metacognition. Educators are encouraged to consider at which point a given learner's reasoning is breaking down. Experimentation with different strategies for improving clinical reasoning can help address learner struggles in each of these domains. In this chapter, various strategies for improving reasoning related to knowledge acquisition, data gathering, data processing, and clinician metacognition will be discussed. Understanding and gaining experience using the different educational strategies will provide practicing physicians with a toolbox of techniques for helping learners improve their reasoning abilities. © 2013 Mosby, Inc.

Mechanism-based strategies for protein thermostabilization.

PubMed

Mozhaev, V V

1993-03-01

Strategies for stabilizing enzymes can be derived from a two-step model of irreversible inactivation that involves preliminary reversible unfolding, followed by an irreversible step. Reversible unfolding is best prevented by covalent immobilization, whereas methods such as covalent modification of amino acid residues or 'medium engineering' (by the addition of low-molecular-weight compounds) are effective against irreversible 'incorrect' refolding. Genetic modification of the protein sequence is the most effective approach for preventing chemical deterioration.

Imbo, Ineke; Vandierendonck, André

2007-04-01

The current study tested the development of working memory involvement in children's arithmetic strategy selection and strategy efficiency. To this end, an experiment in which the dual-task method and the choice/no-choice method were combined was administered to 10- to 12-year-olds. Working memory was needed in retrieval, transformation, and counting strategies, but the ratio between available working memory resources and arithmetic task demands changed across development. More frequent retrieval use, more efficient memory retrieval, and more efficient counting processes reduced the working memory requirements. Strategy efficiency and strategy selection were also modified by individual differences such as processing speed, arithmetic skill, gender, and math anxiety. Short-term memory capacity, in contrast, was not related to children's strategy selection or strategy efficiency.

Insecticide Resistance and Management Strategies in Urban Ecosystems

2016-01-01

The increased urbanization of a growing global population makes imperative the development of sustainable integrated pest management (IPM) strategies for urban pest control. This emphasizes pests that are closely associated with the health and wellbeing of humans and domesticated animals. Concurrently there are regulatory requirements enforced to minimize inadvertent exposures to insecticides in the urban environment. Development of insecticide resistance management (IRM) strategies in urban ecosystems involves understanding the status and mechanisms of insecticide resistance and reducing insecticide selection pressure by combining multiple chemical and non-chemical approaches. In this review, we will focus on the commonly used insecticides and molecular and physiological mechanisms underlying insecticide resistance in six major urban insect pests: house fly, German cockroach, mosquitoes, red flour beetle, bed bugs and head louse. We will also discuss several strategies that may prove promising for future urban IPM programs. PMID:26751480

The role of strategies in motor learning

PubMed Central

Taylor, Jordan A.; Ivry, Richard B.

2015-01-01

There has been renewed interest in the role of strategies in sensorimotor learning. The combination of new behavioral methods and computational methods has begun to unravel the interaction between processes related to strategic control and processes related to motor adaptation. These processes may operate on very different error signals. Strategy learning is sensitive to goal-based performance error. In contrast, adaptation is sensitive to prediction errors between the desired and actual consequences of a planned movement. The former guides what the desired movement should be, whereas the latter guides how to implement the desired movement. Whereas traditional approaches have favored serial models in which an initial strategy-based phase gives way to more automatized forms of control, it now seems that strategic and adaptive processes operate with considerable independence throughout learning, although the relative weight given the two processes will shift with changes in performance. As such, skill acquisition involves the synergistic engagement of strategic and adaptive processes. PMID:22329960

The Role of Microglia and Matrix Metalloproteinases Involvement in Neuroinflammation and Gliomas

2013-01-01

Matrix metalloproteinases (MMPs) are involved in the pathogenesis of neuroinflammatory diseases (such as multiple sclerosis) as well as in the expansion of malignant gliomas because they facilitate penetration of anatomical barriers (such as the glia limitans) and migration within the neuropil. This review elucidates pathomechanisms and summarizes the current knowledge of the involvement of MMPs in neuroinflammation and glioma, invasion highlighting microglia as major sources of MMPs. The induction of expression, suppression, and multiple pathways of function of MMPs in these scenarios will also be discussed. Understanding the induction and action of MMPs might provide valuable information and reveal attractive targets for future therapeutic strategies. PMID:24023566

2013-01-01

PURPOSE We aimed to determine the motivations and barriers facing small practices that seek to adopt the patient-centered medical home (PCMH) model, as well as the type of help and strategies they use. METHODS We surveyed lead physicians at practices with fewer than 5 physicians, stratified by state and level of National Committee for Quality Assurance PCMH recognition, using a Web-based survey with telephone, fax, and mail follow-up. The response rate was 59%, yielding a total sample of 249 practices from 23 states. RESULTS Improving quality and patient experience were the strongest motivations for PCMH implementation; time and resources were the biggest barriers. Most practices participated in demonstration projects or received financial rewards for PCMH, and most received training or other kinds of help. Practices found training and help related to completing the PCMH application to be the most useful. Training for patients was both less common and less valued. The most commonly used strategies for practice transformation were staff training, systematizing processes of care, and quality measurement/goal setting. The least commonly endorsed strategy was involving patients in quality improvement. Practices with a higher level of PCMH recognition were more likely to have electronic health records, to report barriers, and to use measurement-based quality improvement strategies. CONCLUSIONS To spread the adoption of the PCMH model among small practices, financial support, practical training, and other help are likely to continue to be important. Few practices involved patients in their implementation, so it would be helpful to test the impact of greater patient involvement in the PCMH. PMID:23690387

Proactive strategies to avoid infectious disease

PubMed Central

Stevenson, Richard J.; Case, Trevor I.; Oaten, Megan J.

2011-01-01

Infectious disease exerts a large selective pressure on all organisms. One response to this has been for animals to evolve energetically costly immune systems to counter infection, while another—the focus of this theme issue—has been the evolution of proactive strategies primarily to avoid infection. These strategies can be grouped into three types, all of which demonstrate varying levels of interaction with the immune system. The first concerns maternal strategies that function to promote the immunocompetence of their offspring. The second type of strategy influences mate selection, guiding the selection of a healthy mate and one who differs maximally from the self in their complement of antigen-coding genes. The third strategy involves two classes of behaviour. One relates to the capacity of the organisms to learn associations between cues indicative of pathogen threat and immune responses. The other relates to prevention and even treatment of infection through behaviours such as avoidance, grooming, quarantine, medicine and care of the sick. In humans, disease avoidance is based upon cognition and especially the emotion of disgust. Human disease avoidance is not without its costs. There is a propensity to reject healthy individuals who just appear sick—stigmatization—and the system may malfunction, resulting in various forms of psychopathology. Pathogen threat also appears to have been a highly significant and unrecognized force in shaping human culture so as to minimize infection threats. This cultural shaping process—moralization—can be co-opted to promote human health. PMID:22042913

Bottiroli, Sara; Cavallini, Elena; Dunlosky, John; Vecchi, Tomaso; Hertzog, Christopher

2017-09-01

The goal of the present research was to examine the potential of a learner-oriented approach to improving older adults' performance in tasks that are similar to real-life situations that require strategic deployment of cognitive resources. A crucial element of this approach involves encouraging older adults to explicitly analyze tasks to consider how to adapt trained skills to a new task context. In an earlier study, a specialist-directed intervention produced training gains and transfer to some untrained memory tasks. In the present study, older adults received a manual instructing them about principles of task analysis, two memory strategies, and strategy adaptation. Self-guided strategy-adaption training involved practicing some memory tasks as well as instructions on how the trained skills could be applied to new tasks that were not practiced. The criterion tasks involved practice tasks, non-practiced tasks that were discussed in the manual, and transfer tasks that were never mentioned in the manual. Two of the tests were from the Everyday Cognition Battery (inductive reasoning and working memory). As compared to a waiting-list control group, older adults assigned to self-guided strategy-adaption training showed memory improvements on tasks that were practiced or discussed during training. Most important, the learner-oriented approach produced transfer to the everyday tasks. Our findings show the potential of instructing task appraisal processes as a basis for fostering transfer, including improving older adults' performance in simulated everyday tasks.

Bae, Jong-Myon

2017-01-01

As the paradigm in healthcare nowadays is the evidence-based, patient-centered decision making, the issue of shared decision making (SDM) is highlighted. The aims of this manuscript were to look at the relevant concepts and suggest the facilitating strategies for overcoming barriers of conducting SDM. While the definitions of SDM were discordant, several concepts such as good communication, individual autonomy, patient participants, and patient-centered decision-making were involved. Further, the facilitating strategies of SDM were to educate and train physician, to apply clinical practice guidelines and patient decision aids, to develop valid measurement tools for evaluation of SDM processes, and to investigate the impact of SDM.

The effect of hospital control strategies on physician satisfaction and physician-hospital conflict.

PubMed Central

Burns, L R; Andersen, R M; Shortell, S M

1990-01-01

This article examines several strategies that hospitals use to control their medical staffs. Such strategies include placing physicians on salary, developing exclusive hospital affiliations with physicians, and involving physicians in decision-making bodies. Using regression techniques, we investigate which hospitals are more likely to utilize these strategies and whether such strategies are effective in promoting physician-hospital integration. Contrary to our expectations, corporate hospital structures (e.g., for-profit hospitals, membership in multihospital systems) generally do not employ these strategies more often and oftentimes employ them less. There is also little evidence that control strategies are effective levers for increasing physician satisfaction or decreasing physician-hospital conflict. We suggest that control strategies are useful for purposes other than promoting physician-hospital integration. Finally, hospital ownership appears to exert the biggest effect on physician satisfaction and conflict. PMID:2380074

Quantum Strategies and Local Operations

NASA Astrophysics Data System (ADS)

Gutoski, Gus

2010-02-01

This thesis is divided into two parts. In Part I we introduce a new formalism for quantum strategies, which specify the actions of one party in any multi-party interaction involving the exchange of multiple quantum messages among the parties. This formalism associates with each strategy a single positive semidefinite operator acting only upon the tensor product of the input and output message spaces for the strategy. We establish three fundamental properties of this new representation for quantum strategies and we list several applications, including a quantum version of von Neumann's celebrated 1928 Min-Max Theorem for zero-sum games and an efficient algorithm for computing the value of such a game. In Part II we establish several properties of a class of quantum operations that can be implemented locally with shared quantum entanglement or classical randomness. In particular, we establish the existence of a ball of local operations with shared randomness lying within the space spanned by the no-signaling operations and centred at the completely noisy channel. The existence of this ball is employed to prove that the weak membership problem for local operations with shared entanglement is strongly NP-hard. We also provide characterizations of local operations in terms of linear functionals that are positive and "completely" positive on a certain cone of Hermitian operators, under a natural notion of complete positivity appropriate to that cone. We end the thesis with a discussion of the properties of no-signaling quantum operations.

To identify and evaluate coping strategies advocated by experienced animal shelter workers who directly engaged in euthanizing animals. Cross-sectional study. Animal shelters across the United States in which euthanasia was conducted (5 to 100 employees/shelter). With the assistance of experts associated with the Humane Society of the United States, the authors identified 88 animal shelters throughout the United States in which animal euthanasia was actively conducted and for which contact information regarding the shelter director was available. Staff at 62 animal shelters agreed to participate in the survey. Survey packets were mailed to the 62 shelter directors, who then distributed them to employees. The survey included questions regarding respondent age, level of education, and role and asked those directly involved in the euthanasia of animals to provide advice on strategies for new euthanasia technicians to deal with the related stress. Employees completed the survey and returned it by mail. Content analysis techniques were used to summarize survey responses. Coping strategies suggested by 242 euthanasia technicians were summarized into 26 distinct coping recommendations in 8 categories: competence or skills strategies, euthanasia behavioral strategies, cognitive or self-talk strategies, emotional regulation strategies, separation strategies, get-help strategies, seek long-term solution strategies, and withdrawal strategies. Euthanizing animals is a major stressor for many animal shelter workers. Information regarding the coping strategies identified in this study may be useful for training new euthanasia technicians.

Methods for Involving Older People in Health Research-A Review of the Literature.

PubMed

Schilling, Imke; Gerhardus, Ansgar

2017-11-29

Demographic change has increased the need for research on healthcare for older people. Recently there has been a growing awareness that research might benefit from actively involving patients and the public in study design and conduct. Besides empowering patients and democratizing research, involvement enhances the quality of research and the development of equitable healthcare solutions. Little is known about how to involve older people. This review aims to support scientists intending to involve older people in health research by systematically identifying and describing studies involving older people and analyzing associated facilitators and challenges. Old people were operationalized as people living with old-age-related conditions. We conducted a systematic search in PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Cochrane library for the period 2007 to July 2017 and also manually searched reference lists of the nine retrieved articles and other relevant sources. While involvement of older people in research is feasible, specific challenges related to this group need be taken into account. Strategies to enhance effective involvement comprise a thoughtful choice of location, use of visualization and accessible communication, building good relationships and flexible approaches. Further research is needed on the involvement of people in care homes or with vision, hearing or mobility limitations.

Family members (FMs) regularly attend cancer consultations with patients, may assume an array of roles (e.g. emotional, informational) and their involvement may result in benefits and/or challenges. Little is currently known about how oncology health professionals (HPs) view FMs who accompany a patient in consultations. This study aimed to explore the attitudes and practices of Australian oncologists and oncology nurses regarding family involvement in consultations. Eleven oncologists and 10 nurses from a range of subspecialties and tumour streams participated in semi-structured interviews. Interviews were transcribed and qualitatively analysed using framework analysis methods. Five relevant themes were identified: (1) the varied and dynamic nature of family roles during consultations; (2) positivity towards FMs; (3) the benefits of family involvement to the FM themselves; (4) current HP practices to facilitate positive family involvement; and (5) the challenges of family involvement in consultations and HP practices to manage them. Overall, participants held mostly positive attitudes towards family involvement. Although they identified a number of challenges which can arise when family are involved, many noted these situations are the exception, that there are strategies which can help to overcome the challenges, and that the benefits of family involvement typically outweigh the costs. © 2016 John Wiley & Sons Ltd.

Methods 8 participants of a work-related medical rehabilitation were interviewed by telephone 4 weeks after discharge. Qualitative content analysis was used to analyze generated data. Results Beside a poor employer-involvement, the interviews revealed that the process of returning to work was characterized and hampered by unused measures of supporting vocational reintegration during rehabilitation, intersection problems in the health care and social security system, and a strategy of waiting by all involved actors. Conclusion Beside an improved employer-involvement, systematic intersection management and full usage of existing measures are demanded to support vocational reintegration. © Georg Thieme Verlag KG Stuttgart · New York.

Family economic hardship and Chinese adolescents' sleep quality: A moderated mediation model involving perceived economic discrimination and coping strategy.

The association between family economic hardship and adolescent adjustment outcomes, including sleep quality, is well-established. Few studies, however, have examined the mediating and moderating mechanisms underlying the relation between family economic hardship and adolescents' sleep quality. The aim of this study was to investigate the effect of family economic hardship on Chinese adolescents' sleep quality, as well as the role of perceived economic discrimination as a mediator and the role of coping strategy as a moderator. Survey data from a cross-sectional sample of 997 Chinese adolescents (45% male, mean age = 15.04 years) were analyzed using path analysis in Mplus 7.0. The results of this study indicated that family economic hardship was significantly associated with adolescents' sleep quality. This association was mediated by adolescents' perceived economic discrimination. In addition, adolescents' coping strategy significantly moderated the path from perceived economic discrimination to sleep quality, with the "shift" coping strategy as a protective factor. The present study contributes to our understanding of key mechanisms underlying the association between family economic hardship and adolescent sleep quality and highlights the importance of improving sleep quality for adolescents exposed to economic hardship.

NICU nurse educators: what evidence supports your teaching strategies?

PubMed

Pilcher, Jobeth

2013-01-01

One of our roles as nurse educators is to teach best practices related to patient care. However, have you ever stopped to think about what evidence supports your teaching strategies? Just as our patients deserve care that is based on the best available evidence, our learners also deserve education that is based on evidence.1-3 With so many advances in knowledge, technology, and even life itself, it is interesting that education has changed very little over the past 100 years. A study among 946 nurse educators documented that most teach the way they were taught.4 In addition, even after learning new strategies, educators often continue teaching in the manner they are most comfortable. However, this trend is beginning to change. Nurse educators are becoming increasingly aware of and willing to try new and innovative teaching strategies. Educators are also seeking out evidence-based teaching strategies and are becoming more involved in nursing education research.

Feasibility of dsRNA treatment for post-clearing SPF shrimp stocks of newly discovered viral infections using Laem Singh virus (LSNV) as a model.

2017-05-02

Using post-larvae derived from specific pathogen free (SPF) stocks in penaeid shrimp farming has led to a dramatic increase in production. At the same time, new pathogens of farmed shrimp are continually being discovered. Sometimes these pathogens are carried by shrimp and other crustaceans as persistent infections without gross signs of disease. Thus it is that a 5-generation stock of Penaeus monodon SPF for several pathogens was found, post-stock-development, to be persistently-infected with newly-discovered Laem Singh virus (LSNV). In this situation, the stock developers were faced with destroying their existing stock (developed over a long period at considerable cost) and starting the whole stock development process anew in order to add LSNV to its SPF list. As an alternative, it was hypothesized that injection of complementary dsRNA into viral-infected broodstock prior to mating might inhibit replication of the target virus sufficiently to reduce or eliminate its transmission to their offspring. Subsequent selection of uninfected offspring would allow for post-clearing of LSNV from the existing stock and for conversion of the stock to LSNV-free status. Testing this hypothesis using the LSNV-infected stock described above, we found that transmission was substantially reduced in several treated broodstock compared to much higher transmission in buffer-injected broodstock. Based on these results, the model is proposed for post-clearing of SPF stocks using dsRNA treatment. The model may also be applicable to post-clearing of exceptional, individual performers from grow-out ponds for return to a nucleus breeding center. Copyright © 2017 Elsevier B.V.

In 2002 the Idaho Fisheries Resource Office continued working as a cooperator on the Salmon Supplementation Studies in Idaho Rivers (ISS) project on Pete King and Clear creeks. Data relating to supplementation treatment releases, juvenile sampling, juvenile PIT tagging, broodstock spawning and rearing, spawning ground surveys, and snorkel surveys were used to evaluate the project data points and augment past data. Supplementation treatments included the release of 51,329 left ventral-clipped smolts into Clear Creek (750 were PIT tagged), and 12,000 unmarked coded-wire tagged parr into Pete King Creek (998 were PIT tagged). Using juvenile collection methods, Idaho Fisheries Resource Officemore » staff PIT tagged and released 579 naturally produced spring chinook juveniles in Clear Creek, and 54 on Pete King Creek, for minimum survival estimates to Lower Granite Dam. For Clear Creek, minimum survival estimates to Lower Granite Dam of hatchery produced supplementation and naturally produced PIT tagged smolts, were 36.0%, and 53.1%, respectively. For Pete King Creek, minimum survival estimates to Lower Granite Dam, of hatchery produced supplementation smolts and naturally produced smolts PIT tagged as parr and presmolts, were 18.8%, and 8.3%, respectively. Adults collected for broodstock in 2002 represented the final adult broodstock group collected for the ISS project. Twenty-six ventral clipped, and 28 natural adult spring chinook were transported above the weir. Monitoring and evaluation of spawning success was continued on Clear and Pete King creeks. A total of 69 redds were counted and 79 carcasses were recovered on Clear Creek. Two redds were observed and no carcasses were collected on Pete King Creek.« less

To conduct a descriptive review of the concepts related to the practice of healthy habits by identifying the main variables associated with their managment in terms of health promotion actions. In consultation with groups working in health promotion in the city of performed by consulting databases and documentary sources. The strategy and criteria for the selection of documents was previously defined. Finally, we proceeded to organizing and structuring the information. It was established that, to promote healthy habits, four groups of behavior are involved: a) consumption, b) phyisical activity and hygiene, c) safety, and d) social participation. All of these are reviewed in order to point out the main concepts contained in each. The promotion of healthy habits must involve not only the transmission of behaviors associated with them. It must also involve understanding and adapting these habits to the environments of life in which people operate, with consideration for the different roles that they perform and the psychological and cultural demands that each space implies.

Divided multimodal attention sensory trace and context coding strategies in spatially congruent auditory and visual presentation.

PubMed

Kristjánsson, Tómas; Thorvaldsson, Tómas Páll; Kristjánsson, Arni

2014-01-01

Previous research involving both unimodal and multimodal studies suggests that single-response change detection is a capacity-free process while a discriminatory up or down identification is capacity-limited. The trace/context model assumes that this reflects different memory strategies rather than inherent differences between identification and detection. To perform such tasks, one of two strategies is used, a sensory trace or a context coding strategy, and if one is blocked, people will automatically use the other. A drawback to most preceding studies is that stimuli are presented at separate locations, creating the possibility of a spatial confound, which invites alternative interpretations of the results. We describe a series of experiments, investigating divided multimodal attention, without the spatial confound. The results challenge the trace/context model. Our critical experiment involved a gap before a change in volume and brightness, which according to the trace/context model blocks the sensory trace strategy, simultaneously with a roaming pedestal, which should block the context coding strategy. The results clearly show that people can use strategies other than sensory trace and context coding in the tasks and conditions of these experiments, necessitating changes to the trace/context model.

Land Resources Allocation Strategies in an Urban Area Involving Uncertainty: A Case Study of Suzhou, in the Yangtze River Delta of China

A large number of mathematical models have been developed to support land resource allocation decisions and land management needs; however, few of them can address various uncertainties that exist in relation to many factors presented in such decisions (e.g., land resource availabilities, land demands, land-use patterns, and social demands, as well as ecological requirements). In this study, a multi-objective interval-stochastic land resource allocation model (MOISLAM) was developed for tackling uncertainty that presents as discrete intervals and/or probability distributions. The developed model improves upon the existing multi-objective programming and inexact optimization approaches. The MOISLAM not only considers economic factors, but also involves food security and eco-environmental constraints; it can, therefore, effectively reflect various interrelations among different aspects in a land resource management system. Moreover, the model can also help examine the reliability of satisfying (or the risk of violating) system constraints under uncertainty. In this study, the MOISLAM was applied to a real case of long-term urban land resource allocation planning in Suzhou, in the Yangtze River Delta of China. Interval solutions associated with different risk levels of constraint violation were obtained. The results are considered useful for generating a range of decision alternatives under various system conditions, and thus helping decision makers to identify a desirable land resource allocation strategy under uncertainty.

Clinical assessment of organizational strategy: An examination of healthy adults.

PubMed

Banerjee, Pia; White, Desirée A

2015-06-01

During the assessment of patients with cognitive difficulties, clinicians often examine strategic processing, particularly the ability to use organization-based strategies to efficiently complete various tasks. Several commonly used neuropsychological tasks are currently thought to provide measures of organizational strategic processing, but empirical evidence for the construct validity of these strategic measures is needed before interpreting them as measuring the same underlying ability. This is particularly important for the assessment of organizational strategic processing because the measures span cognitive domains (e.g., memory strategy, language strategy) as well as types of organization. In the present study, 200 adults were administered cognitive tasks commonly used in clinical practice to assess organizational strategic processing. Factor analysis was used to examine whether these measures of organizational strategic processing, which involved different cognitive domains and types of organization, could be operationalized as measuring a unitary construct. A very good-fitting model of the data demonstrated no significant shared variance among any of the strategic variables from different tasks (root mean square error of approximation < .0001, standardized root-mean-square residual = .045, comparative fit index = 1.000). These findings suggest that organizational strategic processing is highly specific to the demands and goals of individual tasks even when tasks share commonalities such as involving the same cognitive domain. In the design of neuropsychological batteries involving the assessment of organizational strategic processing, it is recommended that various strategic measures across cognitive domains and types of organizational processing are selected as guided by each patient's individual cognitive difficulties.

The authors investigated gender influences on the nature and competency of preschool children's social problem-solving strategies. Preschool-age children (N = 179; 91 boys, 88 girls) responded to hypothetical social situations designed to assess their social problem-solving skills in the areas of provocation, peer group entry, and sharing or taking turns. Results indicated that, overall, girls' responses were more competent (i.e., reflective of successful functioning with peers) than those of boys, and girls' strategies were less likely to involve retaliation or verbal or physical aggression. The competency of the children's responses also varied with the gender of the target child. Findings are discussed in terms of the influence of gender-related social experiences on the types of strategies and behaviors that may be viewed as competent for boys and girls of preschool age.

Building capacity for service user and carer involvement in research: the implications and impact of best research for best health.

Minogue, Virginia; Girdlestone, John

2010-01-01

The purpose of this paper is to examine the role of service user and carer involvement in NHS research and describe the nature of this involvement in three specialist mental health Trusts. It also aims to discuss the value of service user and carer involvement and present the perspective of the service user and research manager. The paper reviews patient and public involvement policy and practice in the NHS and NHS research. It examines the effectiveness of involvement activity and utilises a case example to demonstrate the impact of patient/service user involvement on the NHS and the individuals who take part. The paper concludes that service user involvement is essential if research is to support the development of health services that clearly reflect the needs of the service user and impact positively on service quality. Service user involvement is an established element of NHS research and development at both national and local level. The Department of Health strategy for research, Best Research for Best Health, reiterates both the importance of research that benefits the patient and the involvement of the service user in the research process. Despite this, the changes in Department of Health support funding for research, introduced by the strategy, may inadvertently lead to some NHS Trusts experiencing difficulty in resourcing this important activity. The paper illustrates the effectiveness of successful patient and public involvement in research. It also identifies how involvement has developed in a fragmented and uncoordinated way and how it is threatened by a failure to embed it more consistently in research infrastructure.

The main purpose of this study is to improve students’ understanding of Highest Common Factor (HCF) and Lowest Common Multiple (LCM). Several alternative teaching strategies were integrated in the Year 7 lessons involving 20 students from one secondary school in Brunei Darussalam. The categories identified in the teaching strategy were the application of group work, embedding real-life problems, using presentations and the traditional drilling practice method. An open-ended survey was disseminated to collate the students’ feedback, and among the questions posed was in relation to the different types of lesson activities utilised within each of the teaching strategies. Although 55% of the students preferred the traditional drilling practice on the calculation of HCF and LCM, mainly due to the ease of the task as opposed to activities involving real-life problems, the findings also indicated that most students favour sharing their ideas in a healthy competition learning style between each other or between the groups.

The mental, physical, social and academic consequences of bullying have an enormous impact on human and social capital. This article describes the effects and prevalence of bullying on young people and presents strategies for its detection. Strategies for the facilitation of a multidisciplinary approach to bullying in adolescents are also presented. Given the existing high rate of bullying, assessment should be incorporated into a standard psychosocial screening routine in the general practitioner's clinic. Effective management is a multidisciplinary effort, involving parents, teachers and school officials, the GP, and mental health professionals. Given the variable effectiveness of schools in tackling bullying, GPs play an important role in identifying at risk patients, screening for psychiatric comorbidities, counselling families about the problem, and advocating for bullying prevention in their communities.

Irritable bowel syndrome is a complex disorder whose pathophysiology involves alterations in the enteric microbiota, visceral hypersensitivity, gut immune/barrier function, hypothalamic-pituitary-adrenal axis regulation, neurotransmitters, stress response, psychological factors, and more. The importance of diet in the management of irritable bowel syndrome has taken center stage in recent times as the literature validates the relationship of certain foods with the provocation of symptoms. Likewise, a number of elimination dietary programs have been successful in alleviating irritable bowel syndrome symptoms. Knowledge of the dietary management strategies for irritable bowel syndrome will help guide nutritionists and healthcare practitioners to deliver optimal outcomes.

Strategy for preventing the waste of human resources

Jones, William E.

1992-05-01

Rapid technological advances and the declining educational preparedness of industrial workers has established a need for new training strategies and initiatives regarding human resource development. The productivity, competitiveness, motivation, and creativity of our people determines whether our business enterprises succeed or fail during the next decade. Due to a change process that many organizations have undertaken to become more competitive toward the year 2000, many of the previous styles of engineering leadership that involves the management of projects and human resources require new approaches. It is also important to recognize that technology has its limits and a broader focus to include the human aspects of accomplishing jobs over the long term is more critical than ever before. More autonomy and the responsibility for broader practices by the professional staff requires that the professional worker operate differently. Business planning and development of the organization's future strategic intent requires a high priority on the human resource linkage to the business plans and strategies. A review of past practices to motivate the worker toward higher productivity clearly shows that past techniques are not as effective in today's work environment. Many practices of organizational and individual leadership don't fit today's approach of worker involvement because they were designed for administrative supervisory control processes. Therefore, if we are going to organize a business strategy that prevents the `waste of human resources,' we need to develop a strategy that is appropriate for the times which considers the attitude of the employees and their work environment. Having worked with scientists and engineers for the majority of my twenty-five year career, I know they see and appreciate the logic of a formula. A formula fits when developing a future strategy because a formula can become a model to enhance balanced planning. In this paper, I want to

This study explored the strategies to overcome diabetes-related social stigma in Iran. This paper is part of an action research study which was designed in Iran in 2012 to plan and implement a program for overcoming diabetes-related stigma. Participants were people with type 1 diabetes, their family members, people without diabetes, and care providers in a diabetes center. Data collection was done through unstructured in-depth interviews, focus groups, e-mail, Short Message Service (SMS), and telephone interview. Data were analyzed using inductive content analysis approach. Participants believed that it is impossible to overcome the stigma without community-based strategies. Community-based strategies include education, advocacy, contact, and protest. The anti-stigma strategies obtained in the study are based on the cultural context in Iran. They are extracted from statements of a wide range of people (with and without diabetes). However, during planning for stigma reduction, it is necessary to note that the effectiveness of social strategies varies in different studies and in different stigmatizing conditions and many factors are involved. These strategies should be implemented simultaneously at different levels to produce structural and social changes. It should be accepted that research on reducing health-related stigma has shown that it is very difficult to change beliefs and behavior. Evidence suggests that individuals and their families should be involved in all aspects of the program, and plans should be made according to the local conditions.

While Illumina microarrays can be used successfully for detecting small gene expression changes due to their high degree of technical replicability, there is little information on how different normalization and differential expression analysis strategies affect outcomes. To evaluate this, we assessed concordance across gene lists generated by applying different combinations of normalization strategy and analytical approach to two Illumina datasets with modest expression changes. In addition to using traditional statistical approaches, we also tested an approach based on combinatorial optimization. We found that the choice of both normalization strategy and analytical approach considerably affected outcomes, in some cases leading to substantial differences in gene lists and subsequent pathway analysis results. Our findings suggest that important biological phenomena may be overlooked when there is a routine practice of using only one approach to investigate all microarray datasets. Analytical artefacts of this kind are likely to be especially relevant for datasets involving small fold changes, where inherent technical variation—if not adequately minimized by effective normalization—may overshadow true biological variation. This report provides some basic guidelines for optimizing outcomes when working with Illumina datasets involving small expression changes. PMID:27605185

Organizational Strategy and Business Environment Effects Based on a Computation Method

According to many researchers of organizational theory, a great number of problems encountered by the manufacturing firms are due to their ineffectiveness to respond to significant changes of their external environment and align their competitive strategy accordingly. From this point of view, the pursuit of the appropriate generic strategy is vital for firms facing a dynamic and highly competitive environment. In the present paper, we adopt Porter's typology to operationalise organizational strategy (cost leadership, innovative and marketing differentiation, and focus) considering changes in the external business environment (dynamism, complexity and munificence). Although simulation of social events is a quite difficult task, since there are so many considerations (not all well understood) involved, in the present study we developed a dynamic system based on the conceptual framework of strategy-environment associations.

Discovery and partial characterization of a non-LTR retrotransposon that may be associated with abdominal segment deformity disease (ASDD) in the whiteleg shrimp Penaeus (Litopenaeus) vannamei

PubMed Central

2013-01-01

Background Abdominal segment deformity disease (ASDD) of cultivated whiteleg shrimp Penaeus (Litopenaeus) vannamei causes economic loss of approximately 10% in affected specimens because of the unsightliness of distorted abdominal muscles. It is associated with the presence of viral-like particles seen by electron microscopy in the ventral nerve cords of affected shrimp. Thus, shotgun cloning was carried out to seek viral-like sequences in affected shrimp. Results A new retrovirus-like element of 5052 bp (named abdominal segment deformity element or ASDE) was compiled by shotgun cloning and 3′ and 5′ RACE using RNA and DNA extracted from ventral nerve cords of ASDD shrimp. ASDE contained 7 putative open reading frames (ORF). One ORF (called the PENS sub-domain), had a deduced amino acid (aa) sequence homologous to the GIY-YIG endonuclease domain of penelope-like retrotransposons while two others were homologous to the reverse transcriptase (RT) and RNaseH domains of the pol gene of non-long terminal repeat (non-LTR) retrotransposons (called the NLRS sub-domain). No single amplicon of 5 kb containing both these elements was obtained by PCR or RT-PCR from ASDD shrimp. Subsequent analysis indicated that PENS and NLRS were not contiguous and that NLRS was a host genetic element. In situ hybridization using a dioxygenin-labeled NLRS probe revealed that NLRS gave positive reactions in abdominal-ganglion neurons of ASDD shrimp but not normal shrimp. Preliminary analysis indicated that long-term use of female broodstock after eyestalk ablation in the hatchery increased the intensity of RT-PCR amplicons for NLRS and also the prevalence of ASDD in mysis 3 offspring of the broodstock. The deformities persist upon further cultivation until shrimp harvest but do not increase in prevalence and do not affect growth or survival. Conclusions Our results suggested that NLRS is a shrimp genetic element associated with ASDD and that immediate preventative measures could include

First, we show that the Ottawa Charter for Health Promotion and the French Charter for Popular Education share common values. Second, an examination of the career and work of Paulo Freire, of Ira Shor's pedagogical model and of the person-centered approach of Carl Rogers shows how the work of educational practitioners, researchers and theorists can help health professionals to implement a truly "health-promoting" or "therapeutic" educational strategy. The paper identifies a number of problems facing health care professionals who become involved in education without reflecting on the values underlying the pedagogical models they use.

Barriers to seamless service delivery between workforce development and mental health systems of care have kept both entities from maximizing their potential in regards to employment for job seekers with mental illness who are capable of work and seeking employment. Using a multiple case study design, this study examined the nature of collaboration between workforce development and mental health systems to understand the policies and practices in place to assist individuals with mental illness to find and keep work. The paper presents innovative strategies that involved staff from both workforce development and mental health agencies. Findings from this research identified the following collaborative strategies: (a) the creation of liaison positions and collaborative teams; (b) staff training on mental health and workforce issues; and (c) multi-level involvement of individuals with mental illness. Implications for workforce professionals are offered as a way to stimulate implementation of such strategies.

Mother Involvement as an Influence on Father Involvement with Early Adolescents

PubMed Central

Pleck, Joseph H.; Hofferth, Sandra L.

2009-01-01

This study hypothesized that father involvement is influenced by mothers' level of involvement as well as by marital conflict, mothers' work hours, and fathers' status as biological or step father. The analysis also tested hypotheses about mother involvement as a potential mediator of the effects of marital conflict and maternal work hours on father involvement, and hypotheses about factors influencing mother involvement. Children aged 10-14 from the NLSY79 who resided with their biological or step father and with their mother reported on each parent's involvement with them. As hypothesized, father involvement was predicted by mother involvement, and the reciprocal influence was not significant. Father involvement was associated with low marital conflict and being a biological father. Mothers' involvement partially mediated the effects of marital conflict on father involvement. If the mediating role of maternal involvement is not taken into account, the effect of marital conflict on father involvement is overestimated. PMID:21776195

2013-07-01

Criminal justice problems among those with bipolar disorder lead to disruption in social functioning, treatment, and recovery. Understanding factors that contribute to arrest during episodes of illness can help inform approaches to risk management and improve clinical care. Data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a longitudinal, nationally representative survey conducted in two waves were used to identify factors that predicted inter-wave criminal justice involvement during bipolar I manic episodes. Over 10% of respondents experienced legal involvement during their most severe manic episode. Risk was found in a range of historical, clinical, and contextual factors. Multivariate analyses suggest risk is particularly high for those who are unemployed, non-white, have past juvenile detention, have a prior arrest (while using substances or when manic), used an illicit drug in the past year, and whose mania is characterized by both social and occupational impairment. Legal problems were particularly elevated among those who lacked health insurance while experiencing both social and occupational impairment. Respondents did not include prisoners and hospital inpatients; criminal justice problems were only assessed with regard to the most severe manic episode. The particular array of factors that elevate the risk of legal involvement during manic episodes offers guidance when identifying prevention strategies and evaluating patients in clinical and forensic settings. Reducing such involvement will require that these issues be dealt with in the broader context of mental health and other services, which in turn necessitates providing adequate access to healthcare.

A primary hemangiopericytoma (HP) of the bone is rare, because the vast majority of these tumors arise in soft tissue. This report presents a case of a hemangiopericytoma in the sacrum (S1-S2) with extension to the retrorectal space. Only a few cases of osseous hemangiopericytomas in the sacrum and involving the retrorectal space have so far been reported. The difficult diagnosis of HP and the surgical strategy was chosen according to the location of the lesion in the sacrum and retrorectal space. A local excision was indicated. A sacral resection should be considered for tumors below S4. This report demonstrated the safety of this strategy. Adjuvant radiotherapy is useful in HP. The value of chemotherapy is still doubtful, although patients with high-grade tumors or metastatic spread seem to gain substantial benefit. Due to the often unpredictable behavior of this neoplasm, extended follow-up is strongly recommended.

2012-01-01

In recent decades the quantity (in weight and volume) of solid waste is grown so rapidly to become a real problem especially in densely urbanized areas. The disposal of Municipal Solid Waste by incineration with energy recovery (WtE) is recognized as the most suitable system to process non-recyclable waste. However in several countries there are still concerns from experts and local communities about the environmental impact of incinerators. Epidemiological studies, developed since the 80s, are still the subject of controversial discussion because the results of research often refer to old incinerators--built a few decades ago--and therefore more impactful. In fact inadequate levels of gas cleaning and combustion process control in these facilities tended to risk the health of plant workers and local environment. This situation furthermore contributes to increase public risk perception and the spread of the NIMBY (not in my backyard) syndrome while siting this unwanted but necessary facilities. Actually, new strategies as advances in emission control designs and very stringent new governmental regulations, have resulted in large reductions in the amount of emissions. So the first aim of this work has been to understand if these high perception of risk have a reason to exist also in modern and new municipal waste incinerators. The second aim is to discover if the law, the new technologies and the mitigation strategies can really set a limit on the negative impacts on human health and on environment and if is it possible to improve or increase these strategies. Work has been divided into two parts. The first part focuses on analysis of waste environmental impact regulations, of plant operation systems and of epidemiological studies results. The second part involves the examination of the actual use of regulatory instruments, the most advanced technologies and the strategies for mitigation in the most effective new concept incinerators plants.

Neural Architecture of Selective Stopping Strategies: Distinct Brain Activity Patterns Are Associated with Attentional Capture But Not with Outright Stopping.

In stimulus-selective stop-signal tasks, the salient stop signal needs attentional processing before genuine response inhibition is completed. Differential prefrontal involvement in attentional capture and response inhibition has been linked to the right inferior frontal junction (IFJ) and ventrolateral prefrontal cortex (VLPFC), respectively. Recently, it has been suggested that stimulus-selective stopping may be accomplished by the following different strategies: individuals may selectively inhibit their response only upon detecting a stop signal (independent discriminate then stop strategy) or unselectively whenever detecting a stop or attentional capture signal (stop then discriminate strategy). Alternatively, the discrimination process of the critical signal (stop vs attentional capture signal) may interact with the go process (dependent discriminate then stop strategy). Those different strategies might differentially involve attention- and stopping-related processes that might be implemented by divergent neural networks. This should lead to divergent activation patterns and, if disregarded, interfere with analyses in neuroimaging studies. To clarify this crucial issue, we studied 87 human participants of both sexes during a stimulus-selective stop-signal task and performed strategy-dependent functional magnetic resonance imaging analyses. We found that, regardless of the strategy applied, outright stopping displayed indistinguishable brain activation patterns. However, during attentional capture different strategies resulted in divergent neural activation patterns with variable activation of right IFJ and bilateral VLPFC. In conclusion, the neural network involved in outright stopping is ubiquitous and independent of strategy, while different strategies impact on attention-related processes and underlying neural network usage. Strategic differences should therefore be taken into account particularly when studying attention-related processes in stimulus

2017-01-01

The purpose of this pilot study was to collect data to inform the development of an HIV prevention program for drug-involved Mexican-Origin (MO) adolescent girls. Eighteen in-depth semi-structured interviews were conducted with drug-involved MO girls in addition to focus group discussions with 19 other drug-involved MO girls and 8 clinical service providers (CSPs) in 2009–2010. Emergent themes indicated that HIV prevention programs for drug-involved MO girls should be girl-centered, focused on relationship development, and include trained peer facilitators who share the same cultural and “street” background as the girls. The program should omit scare tactics associated with risky sexual behaviors and emphasize individual empowerment skills useful to negotiate sexual decisions successfully. In addition, a girl-centered intervention for MO girls should address important concerns for this group, including resistance skills and strategies regarding relationships with older men, teenage motherhood, sexual infidelity, sexual coercion, and dating violence. Participants noted that intervention activities should be interactive with an emphasis on guiding girls as they learn to assess critically personal risk while at the same time learning skills and resources to address these issues in real life.

Previous studies have suggested that spatial navigation can be achieved with at least two distinct learning processes, involving either cognitive map-like representations of the local environment, referred to as the "place strategy", or simple stimulus-response (S-R) associations, the "response strategy". A similar distinction between cognitive/behavioral processes has been made in the context of non-spatial, instrumental conditioning, with the definition of two processes concerning the sensitivity of a given behavior to the expected value of its outcome as well as to the response-outcome contingency ("goal-directed action" and "S-R habit"). Here we investigated whether these two versions of dichotomist definitions of learned behavior, one spatial and the other non-spatial, correspond to each other in a formal way. Specifically, we assessed the goal-directed nature of two navigational strategies, using a combination of an outcome devaluation procedure and a spatial probe trial frequently used to dissociate the two navigational strategies. In Experiment 1, rats trained in a dual-solution T-maze task were subjected to an extinction probe trial from the opposite start arm, with or without prefeeding-induced devaluation of the expected outcome. We found that a non-significant preference for the place strategy in the non-devalued condition was completely reversed after devaluation, such that significantly more animals displayed the use of the response strategy. The result suggests that the place strategy is sensitive to the expected value of the outcome, while the response strategy is not. In Experiment 2, rats with hippocampal lesions showed significant reliance on the response strategy, regardless of whether the expected outcome was devalued or not. The result thus offers further evidence that the response strategy conforms to the definition of an outcome-insensitive, habitual form of instrumental behavior. These results together attest a formal correspondence between

Commercialization of numerous genetically modified organisms (GMOs) has already been approved worldwide, and several additional GMOs are in the approval process. Many countries have adopted legislation to deal with GMO-related issues such as food safety, environmental concerns, and consumers' right of choice, making GMO traceability a necessity. The growing extent of GMO testing makes it important to study optimal GMO detection and identification strategies. This paper formally defines the problem of routine laboratory-level GMO tracking as a cost optimization problem, thus proposing a shift from "the same strategy for all samples" to "sample-centered GMO testing strategies." An algorithm (GMOtrack) for finding optimal two-phase (screening-identification) testing strategies is proposed. The advantages of cost optimization with increasing GMO presence on the market are demonstrated, showing that optimization approaches to analytic GMO traceability can result in major cost reductions. The optimal testing strategies are laboratory-dependent, as the costs depend on prior probabilities of local GMO presence, which are exemplified on food and feed samples. The proposed GMOtrack approach, publicly available under the terms of the General Public License, can be extended to other domains where complex testing is involved, such as safety and quality assurance in the food supply chain.

Evaluations of healthcare interventions, e.g. new drugs or other new treatment strategies, commonly include a cost-effectiveness analysis (CEA) that is based on the application of health economic (HE) models. As end users, patients are important stakeholders regarding the outcomes of CEAs, yet their knowledge of HE model development and application, or their involvement therein, is absent. This paper considers possible benefits and risks of patient involvement in HE model development and application for modellers and patients. An exploratory review of the literature has been performed on stakeholder-involved modelling in various disciplines. In addition, Dutch patient experts have been interviewed about their experience in, and opinion about, the application of HE models. Patients have little to no knowledge of HE models and are seldom involved in HE model development and application. Benefits of becoming involved would include a greater understanding and possible acceptance by patients of HE model application, improved model validation, and a more direct infusion of patient expertise. Risks would include patient bias and increased costs of modelling. Patient involvement in HE modelling seems to carry several benefits as well as risks. We claim that the benefits may outweigh the risks and that patients should become involved.

Home care outsourcing strategy.

Drake, Paul R; Davies, Bethan M

2006-01-01

This paper aims to help public sector managers that are formulating strategies for outsourcing home care from the independent sector. A review was performed of relevant literature on the outsourcing of home care and its political drivers in the U.K. This indicates that the future of home care services, taking into consideration outsourcing and how Best Value will be achieved, has not been researched widely. Therefore, an exploratory approach to research was adopted here using in-depth analysis of a small number of particularly informative local authorities and private providers selected by purposive/judgemental (extreme and critical case) sampling. Personal contact was deemed necessary in order to perform an intensive investigation to pursue in-depth information. The British Government's Best Value regime is driving local authorities towards increasing levels of outsourcing in the provision of home care. A local authority may choose to outsource all of its home care or maintain some in-house provision based on capacity or capabilities that are complementary to those provided by the independent sector. The 100 per cent outsourcing strategy places enabling demands on the local authority, whereas the alternative strategy requires decisions to be made on what should be outsourced. Across the authorities surveyed, six strategies for creating a mixed economy of care have been identified, with the mix being based on complementary capacity and/or capabilities. With Best Value driving authorities to consider lower-cost options, the outcome may be a reduction in the amount of complementary capacity provided in-house, in favour of strategies involving complementary capabilities that deliver the Best Value possible. Re-enablement is emerging as a common, complementary or core capability that is remaining in-house. Outsourcing also requires decisions to be made on the number of independent providers to be used and the type of contracts to be employed. This paper considers the

Appropriate marketing business systems need to be in place to attract and sustain a cosmetic dentistry patient base. Marketing for this sector is most effective when consistently patterned after businesses with high-end consumer services and products. Motivating patients of record and potential new patients to choose cosmetic dental services involves implementing both basic marketing and a series of cosmetic-specific marketing strategies. Consultants are valuable for the process of developing a strategic plan and making recommendations for developing new marketing business systems.

Cost-Utility Analysis of Screening Strategies for Diabetic Retinopathy in Korea.

This study involved a cost-utility analysis of early diagnosis and treatment of diabetic retinopathy depending on the screening strategy used. The four screening strategies evaluated were no screening, opportunistic examination, systematic fundus photography, and systematic examination by an ophthalmologists. Each strategy was evaluated in 10,000 adults aged 40 yr with newly diagnosed diabetes mellitus (hypothetical cohort). The cost of each strategy was estimated in the perspective of both payer and health care system. The utility was estimated using quality-adjusted life years (QALY). Incremental Cost Effectiveness Ratio (ICER) for the different screening strategies was analyzed. After exclusion of the weakly dominating opportunistic strategy, the ICER of systematic photography was 57,716,867 and that of systematic examination by ophthalmologists was 419,989,046 from the perspective of the healthcare system. According to the results, the systematic strategy is preferable to the opportunistic strategy from the perspective of both a payer and a healthcare system. Although systematic examination by ophthalmologists may have higher utility than systematic photography, it is associated with higher cost. The systematic photography is the best strategy in terms of cost-utility. However systematic examination by ophthalmologists can also be a suitable policy alternative, if the incremental cost is socially acceptable.

Rainfall-triggered landslides, anthropogenic hazards, and mitigation strategies

2008-01-01

Rainfall-triggered landslides are part of a natural process of hillslope erosion that can result in catastrophic loss of life and extensive property damage in mountainous, densely populated areas. As global population expansion on or near steep hillslopes continues, the human and economic costs associated with landslides will increase. Landslide hazard mitigation strategies generally involve hazard assessment mapping, warning systems, control structures, and regional landslide planning and policy development. To be sustainable, hazard mitigation requires that management of natural resources is closely connected to local economic and social interests. A successful strategy is dependent on a combination of multi-disciplinary scientific and engineering approaches, and the political will to take action at the local community to national scale.

2009-04-01

Pedicle involvement in spinal tuberculosis (TB), the prevertebral abscess formation, severity of vertebral body, and disc collapse were evaluated from magnetic resonance imaging (MRI) of the patients. To study the pedicle involvement in spine TB in relation to the degree of vertebral body and disc collapse, prevertebral abscess collection, and degree of kyphosis; and to correlate the occurrence of pedicle involvement and the degree of spinal deformity. There are a few reports describing the posterior element involvement in spinal TB. Typically, the infection resides in the anterior part of the vertebral body endplates and rarely involved the pedicles. There were 31 patients, who had been diagnosed and treated for spinal TB from 2003 to 2007 at our center. Critical evaluation of each patient's MRI was carried out for the pedicle involvement, prevertebral abscess formation, severity of vertebral body, and disc collapse. Spinal TB mostly involved the thoracic level (48.4%). Pedicle involvement was noted in 64.5% of patients, and the highest involvement was at thoracic level. The mean vertebral body, disc collapse, prevertebral abscess, and kyphosis were more severe in pedicle involved group. The posterior spinal element, specifically the pedicle is not uncommonly involved in spinal TB. Pedicle involvement is part of the disease process and usually associated with relatively severe vertebral body and disc destruction, wide prevertebral abscess, and severe kyphosis. Pedicle involvement can be detected early from MRI and need to be documented as it may influence the treatment strategy.

Nanomedicine Strategies to Target Tumor-Associated Macrophages

Binnemars-Postma, Karin; Storm, Gert; Prakash, Jai

2017-01-01

In recent years, the influence of the tumor microenvironment (TME) on cancer progression has been better understood. Macrophages, one of the most important cell types in the TME, exist in different subtypes, each of which has a different function. While classically activated M1 macrophages are involved in inflammatory and malignant processes, activated M2 macrophages are more involved in the wound-healing processes occurring in tumors. Tumor-associated macrophages (TAM) display M2 macrophage characteristics and support tumor growth and metastasis by matrix remodeling, neo-angiogenesis, and suppressing local immunity. Due to their detrimental role in tumor growth and metastasis, selective targeting of TAM for the treatment of cancer may prove to be beneficial in the treatment of cancer. Due to the plastic nature of macrophages, their activities may be altered to inhibit tumor growth. In this review, we will discuss the therapeutic options for the modulation and targeting of TAM. Different therapeutic strategies to deplete, inhibit recruitment of, or re-educate TAM will be discussed. Current strategies for the targeting of TAM using nanomedicine are reviewed. Passive targeting using different nanoparticle systems is described. Since TAM display a number of upregulated surface proteins compared to non-TAM, specific targeting using targeting ligands coupled to nanoparticles is discussed in detail. PMID:28471401

From tokenism to empowerment: progressing patient and public involvement in healthcare improvement

Ocloo, Josephine; Matthews, Rachel

2016-01-01

Background There have been repeated calls to better involve patients and the public and to place them at the centre of healthcare. Serious clinical and service failings in the UK and internationally increase the urgency and importance of addressing this problem. Despite this supportive policy context, progress to achieve greater involvement is patchy and slow and often concentrated at the lowest levels of involvement. Methods A selective narrative literature search was guided by the authors’ broad expertise, covering a range of disciplines across health and social care, policy and research. Published systematic literature reviews were used to identify relevant authors and publications. Google and hand searches of journal articles and reference lists and reports augmented identification of recent evidence. Results Patients and the wider public can be involved at most stages of healthcare, and this can have a number of benefits. Uncertainty persists about why and how to do involvement well and evaluate its impact, how to involve and support a diversity of individuals, and in ways that allow them to work in partnership to genuinely influence decision-making. This exposes patient and public involvement (PPI) to criticisms of exclusivity and tokenism. Conclusions Current models of PPI are too narrow, and few organisations mention empowerment or address equality and diversity in their involvement strategies. These aspects of involvement should receive greater attention, as well as the adoption of models and frameworks that enable power and decision-making to be shared more equitably with patients and the public in designing, planning and co-producing healthcare.

Conceptual change strategies in teaching genetics

NASA Astrophysics Data System (ADS)

Batzli, Laura Elizabeth

The purpose of this study was to evaluate the effectiveness of utilizing conceptual change strategies when teaching high school genetics. The study examined the effects of structuring instruction to provide students with cognitive situations which promote conceptual change, specifically instruction was structured to elicit students' prior knowledge. The goal of the study was that the students would not only be able to solve genetics problems and define basic terminology but they would also have constructed more scientific schemas of the actual processes involved in inheritance. This study is based on the constructivist theory of learning and conceptual change research which suggest that students are actively involved in the process of relating new information to prior knowledge as they construct new knowledge. Two sections of biology II classes received inquiry based instruction and participated in structured cooperative learning groups. However, the unique difference in the treatment group's instruction was the use of structured thought time and the resulting social interaction between the students. The treatment group students' instructional design allowed students to socially construct their cognitive knowledge after elicitation of their prior knowledge. In contrast, the instructional design for the control group students allowed them to socially construct their cognitive knowledge of genetics without the individually structured thought time. The results indicated that the conceptual change strategies with individually structured thought time improved the students' scientific mastery of genetics concepts and they maintained fewer post instructional alternative conceptions. Although all students gained the ability to correctly solve genetics problems, the treatment group students were able to explain the processes involved in terms of meiosis. The treatment group students were also able to better apply their knowledge to novel genetic situations. The implications

2014-11-01

The strategy of sharing program decision-making with youth in youth programs, a specific form of youth-adult partnership, is widely recommended in practitioner literature; however, empirical study is relatively limited. We investigated the prevalence and correlates of youth program decision-making practices (e.g., asking youth to help decide what activities are offered), using single-level and multilevel methods with a cross-sectional dataset of 979 youth attending 63 multipurpose after-school programs (average age of youth = 11.4, 53 % female). The prevalence of such practices was relatively high, particularly for forms that involved low power sharing such as involving youth in selecting the activities a program offers. Hierarchical linear modeling revealed positive associations between youth program decision-making practices and youth motivation to attend programs. We also found positive correlations between decision-making practices and youth problem-solving efficacy, expression efficacy, and empathy. Significant interactions with age suggest that correlations with problem solving and empathy are more pronounced for older youth. Overall, the findings suggest that involving youth in program decision-making is a promising strategy for promoting youth motivation and skill building, and in some cases this is particularly the case for older (high school-age) youth.

Internal quality control: planning and implementation strategies.

Westgard, James O

2003-11-01

The first essential in setting up internal quality control (IQC) of a test procedure in the clinical laboratory is to select the proper IQC procedure to implement, i.e. choosing the statistical criteria or control rules, and the number of control measurements, according to the quality required for the test and the observed performance of the method. Then the right IQC procedure must be properly implemented. This review focuses on strategies for planning and implementing IQC procedures in order to improve the quality of the IQC. A quantitative planning process is described that can be implemented with graphical tools such as power function or critical-error graphs and charts of operating specifications. Finally, a total QC strategy is formulated to minimize cost and maximize quality. A general strategy for IQC implementation is recommended that employs a three-stage design in which the first stage provides high error detection, the second stage low false rejection and the third stage prescribes the length of the analytical run, making use of an algorithm involving the average of normal patients' data.

Community and individual involvement are essential needs in preventive programmes for periodontal health. Campaigns should be directed towards a better individual understanding of the importance of healthy gum tissues if a functional healthy dentition is to be retained over a lifetime. Effective awareness campaigns require not only participation and education of the general public, but also all levels of health care professionals. Awareness programmes need to be carefully planned and their messages clear, non-conflicting and regularly reinforced. The complete programme should be based on, and include, specific aims, goals, strategies, monitoring and evaluation. Oral health and hygiene promotion campaigns need careful coordination between the relevant agencies or institutions involved in their implementation, such as government agencies, professional associations, industry, aid groups and education organisations.

Multilevel Mechanisms of Implementation Strategies in Mental Health: Integrating Theory, Research, and Practice

2015-01-01

A step toward the development of optimally effective, efficient, and feasible implementation strategies that increase evidence-based treatment integration in mental health services involves identification of the multilevel mechanisms through which these strategies influence implementation outcomes. This article (a) provides an orientation to, and rationale for, consideration of multilevel mediating mechanisms in implementation trials, and (b) systematically reviews randomized controlled trials that examined mediators of implementation strategies in mental health. Nine trials were located. Mediation-related methodological deficiencies were prevalent and no trials supported a hypothesized mediator. The most common reason was failure to engage the mediation target. Discussion focuses on directions to accelerate implementation strategy development in mental health. PMID:26474761

Dhaka's community-based decentralized composting (DCDC) is a successful demonstration of solid waste management by adopting low-cost technology, local resources community participation and partnerships among the various actors involved. This paper attempts to understand the model, necessary conditions, strategies and their priorities to replicate DCDC in the other developing cities of Asia. Thirteen strategies required for its replication are identified and assessed based on various criteria, namely transferability, longevity, economic viability, adaptation and also overall replication. Priority setting by multi-criteria analysis by applying analytic hierarchy process revealed that immediate transferability without long-term and economic viability consideration is not advisable as this would result in unsustainable replication of DCDC. Based on the analysis, measures to ensure the product quality control; partnership among stakeholders (public-private-community); strategies to achieve better involvement of the private sector in solid waste management (entrepreneurship in approach); simple and low-cost technology; and strategies to provide an effective interface among the complementing sectors are identified as important strategies for its replication.

This study investigated perceived strategies and activities for successful later aging. Participants were 242 members of the Terman Study of the Gifted who responded to an open-ended question concerning how they make the most of their aging years. Data were collected in 1996 and 1999, when the participants were average ages of 84 and 86. Longitudinal analyses examined changes over time and cross-sectional analyses examined correlates of strategies and activities. Results showed that strategies emphasized emotion regulation and adaptation. Activities emphasized family involvement, social relationships, leisure, productive and intellectual activity, and health maintenance. Reports of emotion regulation and adaptation increased over time and mention of an intellectual orientation declined over time. Variations in activity mention were found according to gender, age, self-rated health, health limitations, and life satisfaction. History of higher-level occupations was related to more productive activities. Results are discussed in terms of the challenges of later aging.

Squamous cell carcinoma (SCC) of the buccal mucosa is an aggressive oral cancer. It mainly occurs in Central and Southeast Asia, and is closely related to the practice of tobacco smoking and betel squid chewing. The high recurrence and low survival rates of buccal SCC require our continued efforts to understand the pathogenesis of the disease for designing better therapeutic strategies. We used proteomic technology to analyze buccal SCC tissues aiming at identifying tumor-associated proteins for the utilization as biomarkers or molecular targets. With the exception of alpha B-crystallin being substantially reduced, a number of proteins were found to be significantly over-expressed in cancer tissues. These increased proteins included glycolytic enzymes, heat-shock proteins, tumor antigens, cytoskeleton proteins, enzymes involved in detoxification and anti-oxidation systems, and proteins involved in mitochondrial and intracellular signaling pathways. These extensive protein variations indicate that multiple cellular pathways were involved in the process of tumorigenesis, and suggest that multiple protein molecules should be simultaneously targeted as an effective strategy to counter the disease. At least, SCC antigen, G protein, glutathione S-transferase, manganese superoxide dismutase, annexins, voltage-dependent anion channel, cyclophilin A, stratifin and galectin 7 are candidates for targeted proteins. The present findings also demonstrated that rich protein information can be produced by means of proteomic analysis for a better understanding of the oncogenesis and pathogenesis in a global way, which in turn is a basis for the rational designs of diagnostic and therapeutic methods.

Structure coefficients and strategy selection in multiplayer games.

PubMed

McAvoy, Alex; Hauert, Christoph

2016-01-01

Evolutionary processes based on two-player games such as the Prisoner's Dilemma or Snowdrift Game are abundant in evolutionary game theory. These processes, including those based on games with more than two strategies, have been studied extensively under the assumption that selection is weak. However, games involving more than two players have not received the same level of attention. To address this issue, and to relate two-player games to multiplayer games, we introduce a notion of reducibility for multiplayer games that captures what it means to break down a multiplayer game into a sequence of interactions with fewer players. We discuss the role of reducibility in structured populations, and we give examples of games that are irreducible in any population structure. Since the known conditions for strategy selection, otherwise known as [Formula: see text]-rules, have been established only for two-player games with multiple strategies and for multiplayer games with two strategies, we extend these rules to multiplayer games with many strategies to account for irreducible games that cannot be reduced to those simpler types of games. In particular, we show that the number of structure coefficients required for a symmetric game with [Formula: see text]-player interactions and [Formula: see text] strategies grows in [Formula: see text] like [Formula: see text]. Our results also cover a type of ecologically asymmetric game based on payoff values that are derived not only from the strategies of the players, but also from their spatial positions within the population.

Quality of the parent-infant relationship influences the mechanisms of development of the child's physiological stress regulation. This study explored associations between attachment strategies and both cortisol and thyroid stimulating hormone, hypothesized to be respectively a potential mediator and a potential intervening variable of the mother-child relationship in obese children. A sample of 83 obese children (46 boys), aged 10.9 (1.8) years was recruited from a child obesity clinic. Obesity was defined by body mass index percentile adjusted for age and sex. Metabolic biomarkers were measured by routine methods. Attachment strategies were assessed with self and parent-report questionnaires. Family functioning was assessed with parent-reported questionnaires (FACES-III). Multivariate linear regression analyses were performed. Type A, avoidant attachment strategies, had significant positive association with thyroid stimulating hormone levels and negative association with cortisol levels (R2 = 0.352). Type B, secure attachment strategies, had significant positive associations with both hypothyroidism and body mass index percentile (R2 = 0.541). 'Insecure attachment' (types A and C combined) strategies showed some evidence of positive association with thyroid stimulating hormone (R2 = 0.250). These findings suggest that there may be commonalities in the regulation of hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axes. Processes involved in development of the type A attachment strategy appear to be associated with effects on the regulatory mechanisms of the hypothalamic-pituitary-adrenal axis. In obese children, different attachment strategies are associated with diverse metabolic profiles. How this may contribute to developing differentiated treatment approaches remains to be explored.

Task-level strategies for human sagittal-plane running maneuvers are consistent with robotic control policies.

PubMed

Qiao, Mu; Jindrich, Devin L

2012-01-01

The strategies that humans use to control unsteady locomotion are not well understood. A "spring-mass" template comprised of a point mass bouncing on a sprung leg can approximate both center of mass movements and ground reaction forces during running in humans and other animals. Legged robots that operate as bouncing, "spring-mass" systems can maintain stable motion using relatively simple, distributed feedback rules. We tested whether the changes to sagittal-plane movements during five running tasks involving active changes to running height, speed, and orientation were consistent with the rules used by bouncing robots to maintain stability. Changes to running height were associated with changes to leg force but not stance duration. To change speed, humans primarily used a "pogo stick" strategy, where speed changes were associated with adjustments to fore-aft foot placement, and not a "unicycle" strategy involving systematic changes to stance leg hip moment. However, hip moments were related to changes to body orientation and angular speed. Hip moments could be described with first order proportional-derivative relationship to trunk pitch. Overall, the task-level strategies used for body control in humans were consistent with the strategies employed by bouncing robots. Identification of these behavioral strategies could lead to a better understanding of the sensorimotor mechanisms that allow for effective unsteady locomotion.

The use of medicines is an action that involves a change in behaviour and it is a complex construct involving reciprocal interactions between social, environmental and cognitive factors. This is particularly true when a patient uses medicines for asymptomatic chronic conditions, requiring life-long use. To identify patient-perceived medication use challenges, determine the coping strategies used and investigate the relationship between patient-perceived challenges and self-initiation of coping strategies. A premier 900-bed tertiary/teaching hospital located in Ibadan, Nigeria. Ten pharmacists conducted cross-sectional medication use interviews for a random sample of 324 medical outpatients in 4 weeks (25th October-19th November 2006). Patient-perceived challenges with prescribed medications, self-initiated coping strategies used and relationship between patient-perceived challenges and self-initiation of coping strategies Eighty-one percent (324) of the random sample of 400 patients consented and completed the interview. Of these, 50.3 % were males while 49.7 % were females with mean age (SD) of 51.5 (17.6) and 52.1 (17.4) years respectively. The most frequent diagnoses were hypertension (53 %) and type-2 diabetes + hypertension (14.5 %). Two hundred and twenty-four patients reported one or more perceived challenges. Of these, 43.8 % were 65 years or older and about half reported at least 3 challenges. The majority (95.6 %) of patients who reported perceived challenges initiated one or more coping strategies without the knowledge of their physicians or pharmacists. Of 100 patients who did not report any perceived challenge, 43 % admitted initiating strategies to maintain perceived "cure" of their medical conditions. Self-initiation and use of coping strategies was far more likely among patients who reported perceived challenges (OR: 28.4, 95 % CI 26.1-30.5). The number of coping strategies reported appeared strongly related to the number of perceived challenges (r

Self-change is the most frequent way people limit or reduce gambling involvement and often the first choice of people experiencing gambling-related problems. Less well known is the range of change strategies gamblers use and how these are selected, initiated or maintained. This study examined change strategies discussed in counselling transcripts from 149 clients who accessed a national online gambling help service in Australia. Using thematic analysis, we identified the presence of six change strategies; cash control and financial management, social support, avoiding or limiting gambling, alternative activities, changing thoughts and beliefs, and self-assessment and monitoring. Four implementation issues were also identified; a mismatch between need and strategy selection or maintenance; importance and readiness versus the cost of implementation; poor or unplanned transitions between strategies; and failure to review the helpfulness of strategies resulting in premature abandonment or unhelpful prolonged application. This study is the first to identify change strategies discussed in online counselling sessions. This study suggests change strategies are frequently discussed in online counselling sessions and we identified multiple new actions associated with change strategies that had not previously been identified. However, multiple implementation issues were identified and further work is required to determine the helpfulness of change strategies in terms of their selection, initiation and maintenance.

Most people with common mental disorders (CMDs) are employed and working, but few studies have looked into how they manage their jobs while ill. This study explores workers' experiences of strategies to keep working while suffering from CMDs. In this grounded theory study, we interviewed 19 women and eight men with depression or anxiety disorders. They were 19-65 years old and had different occupations. Constant comparison method was used in the analysis. We identified a core pattern in the depressed and anxious workers' attempts to sustain their capacities, defined as Managing work space. The core pattern comprised four categories describing different cognitive, behavioral, and social strategies. The categories relate to a process of sustainability. Two categories reflected more reactive and temporary strategies, occurring mainly in the onset phase of illness: Forcing the work role and Warding off work strain. The third category, Recuperating from work, reflected strategies during both onset and recovery phases. The fourth category, Reflexive adaptation, was present mainly in the recovery phase and involved reflective strategies interpreted as more sustainable over time. The results can deepen understanding among rehabilitation professionals about different work-related strategies in depressed and anxious workers. Increased awareness of the meaning and characteristics of strategies can inform a person-oriented approach in rehabilitation. The knowledge can be used in clinical encounters to reflect together with the patient, exploring present options and introducing modifications to their particular work and life context. Implications for rehabilitation Self-managed work functioning in common mental disorders involves diverse strategies. Strategies interpreted as sustainable over time, seem to be reflective in the sense that the worker consciously applies and adapts the strategies. However, at the onset of illness, such reflection is difficult to develop as the

Oligo/Polynucleotide-Based Gene Modification: Strategies and Therapeutic Potential

PubMed Central

Sargent, R. Geoffrey; Kim, Soya

2011-01-01

Oligonucleotide- and polynucleotide-based gene modification strategies were developed as an alternative to transgene-based and classical gene targeting-based gene therapy approaches for treatment of genetic disorders. Unlike the transgene-based strategies, oligo/polynucleotide gene targeting approaches maintain gene integrity and the relationship between the protein coding and gene-specific regulatory sequences. Oligo/polynucleotide-based gene modification also has several advantages over classical vector-based homologous recombination approaches. These include essentially complete homology to the target sequence and the potential to rapidly engineer patient-specific oligo/polynucleotide gene modification reagents. Several oligo/polynucleotide-based approaches have been shown to successfully mediate sequence-specific modification of genomic DNA in mammalian cells. The strategies involve the use of polynucleotide small DNA fragments, triplex-forming oligonucleotides, and single-stranded oligodeoxynucleotides to mediate homologous exchange. The primary focus of this review will be on the mechanistic aspects of the small fragment homologous replacement, triplex-forming oligonucleotide-mediated, and single-stranded oligodeoxynucleotide-mediated gene modification strategies as it relates to their therapeutic potential.

Vestibular pathways involved in cognition

Hitier, Martin; Besnard, Stephane; Smith, Paul F.

2014-01-01

Recent discoveries have emphasized the role of the vestibular system in cognitive processes such as memory, spatial navigation and bodily self-consciousness. A precise understanding of the vestibular pathways involved is essential to understand the consequences of vestibular diseases for cognition, as well as develop therapeutic strategies to facilitate recovery. The knowledge of the “vestibular cortical projection areas”, defined as the cortical areas activated by vestibular stimulation, has dramatically increased over the last several years from both anatomical and functional points of view. Four major pathways have been hypothesized to transmit vestibular information to the vestibular cortex: (1) the vestibulo-thalamo-cortical pathway, which probably transmits spatial information about the environment via the parietal, entorhinal and perirhinal cortices to the hippocampus and is associated with spatial representation and self-versus object motion distinctions; (2) the pathway from the dorsal tegmental nucleus via the lateral mammillary nucleus, the anterodorsal nucleus of the thalamus to the entorhinal cortex, which transmits information for estimations of head direction; (3) the pathway via the nucleus reticularis pontis oralis, the supramammillary nucleus and the medial septum to the hippocampus, which transmits information supporting hippocampal theta rhythm and memory; and (4) a possible pathway via the cerebellum, and the ventral lateral nucleus of the thalamus (perhaps to the parietal cortex), which transmits information for spatial learning. Finally a new pathway is hypothesized via the basal ganglia, potentially involved in spatial learning and spatial memory. From these pathways, progressively emerges the anatomical network of vestibular cognition. PMID:25100954

Empathy and involvement in bullying in children and adolescents: a systematic review.

Based on the premise that bullies are deficient in empathy or even lack it completely, bullying prevention and intervention programs often include empathy training. These programs are not always as effective as they aim to be, which may be caused by a failure to acknowledge the multidimensional nature of empathy as well as its complex association with involvement in bullying. To provide a clear overview of the research on the association between empathy and involvement in bullying, this article systematically reviews 40 studies on the association of cognitive empathy (24 studies) and affective empathy (38 studies) with four categories of involvement in bullying: bullying, victimization, defending, and bystanding. The results showed that bullying was negatively associated with cognitive and-in particular-affective empathy. Victimization was negatively associated with cognitive empathy but not with affective empathy. Defending was consistently positively associated with both types of empathy. Contradictory findings were observed in bystanding, with studies reporting both negative and positive associations with cognitive empathy, and studies reporting negative and no associations with affective empathy. Together, the findings stress the importance of the distinction between cognitive and affective empathy in involvement in bullying and suggest different intervention strategies for the four types of involvement in bullying.

Literature review/semi-structured interviews. To develop a spinal cord injury (SCI) research strategy for Australia and New Zealand. Australia. The National Trauma Research Institute Forum approach of structured evidence review and stakeholder consultation was employed. This involved gathering from published literature and stakeholder consultation the information necessary to properly consider the challenge, and synthesising this into a briefing document. A research strategy 'roadmap' was developed to define the major steps and key planning questions to consider; next, evidence from published SCI research strategy initiatives was synthesised with information from four one-on-one semi-structured interviews with key SCI research stakeholders to create a research strategy framework, articulating six key themes and associated activities for consideration. These resources, combined with a review of SCI prioritisation literature, were used to generate a list of draft principles for discussion in a structured stakeholder dialogue meeting. The research strategy roadmap and framework informed discussion at a structured stakeholder dialogue meeting of 23 participants representing key SCI research constituencies, results of which are published in a companion paper. These resources could also be of value in other research strategy or planning exercises. This project was funded by the Victorian Transport Accident Commission and the Australian and New Zealand Spinal Cord Injury Network.

The Chief Joseph Hatchery is the fourth hatchery obligated under the Grand Coulee Dam/Dry Falls project, originating in the 1940s. Leavenworth, Entiat, and Winthrop National Fish Hatcheries were built and operated as mitigation for salmon blockage at Grand Coulee Dam, but the fourth hatchery was not built, and the obligation was nearly forgotten. After the Colville Tribes successfully collaborated with the United States to resurrect the project, planning of the hatchery began in 2001 and construction was completed in 2013. The monitoring program began in 2012 and adult Chinook Salmon were brought on station for the first time in June 2013. BPA is the primary funding source for CJH, and the Mid-Columbia PUDs (Douglas, Grant and Chelan County) have entered into cost-share agreements with the tribes and BPA in order to meet some of their mitigation obligations. The CJH production level was set at 60% in 2013 in order to train staff and test hatchery facility systems during the first year of operation. Leavenworth National Fish Hatchery (LNFH) provided 422 Spring Chinook broodstock in June, 2013; representing the official beginning of CJH operations. In July and August the CCT used a purse seine vessel to collect 814 summer/fall Chinook as broodstock that were a continuation and expansion of the previous Similkameen Pond program. In-hatchery survival for most life stages exceeded survival targets and, as of April 2014, the program was on track to exceed the 60% production target for its start-up year. The CJH monitoring project collected field data to determine Chinook population status, trend, and hatchery effectiveness centered on five major activities; 1) rotary screw traps (juvenile outmigration, natural-origin smolt PIT tagging) 2) beach seine (naturalorigin smolt PIT tagging) 3) lower Okanogan adult fish pilot weir (adult escapement, proportion of hatchery-origin spawners [pHOS], broodstock) 4) spawning ground surveys (redd and carcass surveys)(viable salmonid

In 2005 the Spanish National Health System (SNHS) implemented a strategy aimed at improving patient safety in Spanish healthcare centres. Promote and develop knowledge of patient safety and a patient safety culture among health professionals and patients; design and implement adverse event information and reporting systems for learning purposes; introduce recommended safe practices in SNHS centres; promote patient safety research and public and patient involvement in patient safety policies. An Institutional Technical Committee was created with representatives from all the Spanish regions. All national organizations involved in healthcare quality and patient safety took part in the project. The strategy follows the WHO World Alliance for Patient Safety and Council of Europe recommendations. Budget allocated in the period 2005-2007: approximately EUR35 million. Around 5,000 health professionals were educated in PS concepts. Several studies were conducted on: adverse events in Hospitals and Primary Care, as well as studies to obtain information on health professionals' perceptions on safety, the use of medications and the situation regarding hospital-acquired infections. All the regions have introduced safe clinical practices related with the strategy. The strategy has been implemented in all the Spanish regions. Awareness was raised among health professionals and the public. A network of alliances has been set up with the regions, universities, schools, agencies and other organizations supporting the strategy.

Long range personalized cancer treatment strategies incorporating evolutionary dynamics.

Current cancer precision medicine strategies match therapies to static consensus molecular properties of an individual's cancer, thus determining the next therapeutic maneuver. These strategies typically maintain a constant treatment while the cancer is not worsening. However, cancers feature complicated sub-clonal structure and dynamic evolution. We have recently shown, in a comprehensive simulation of two non-cross resistant therapies across a broad parameter space representing realistic tumors, that substantial improvement in cure rates and median survival can be obtained utilizing dynamic precision medicine strategies. These dynamic strategies explicitly consider intratumoral heterogeneity and evolutionary dynamics, including predicted future drug resistance states, and reevaluate optimal therapy every 45 days. However, the optimization is performed in single 45 day steps ("single-step optimization"). Herein we evaluate analogous strategies that think multiple therapeutic maneuvers ahead, considering potential outcomes at 5 steps ahead ("multi-step optimization") or 40 steps ahead ("adaptive long term optimization (ALTO)") when recommending the optimal therapy in each 45 day block, in simulations involving both 2 and 3 non-cross resistant therapies. We also evaluate an ALTO approach for situations where simultaneous combination therapy is not feasible ("Adaptive long term optimization: serial monotherapy only (ALTO-SMO)"). Simulations utilize populations of 764,000 and 1,700,000 virtual patients for 2 and 3 drug cases, respectively. Each virtual patient represents a unique clinical presentation including sizes of major and minor tumor subclones, growth rates, evolution rates, and drug sensitivities. While multi-step optimization and ALTO provide no significant average survival benefit, cure rates are significantly increased by ALTO. Furthermore, in the subset of individual virtual patients demonstrating clinically significant difference in outcome between

Screening and brief interventions (SBI) delivered in primary health care (PHC) are cost-effective in decreasing alcohol consumption; however, they are underused. This study aims to identify implementation strategies that focus on SBI uptake and measure impact on: (1) heavy drinking and (2) delivery of SBI in PHC. Meta-analysis was conducted of controlled trials of SBI implementation strategies in PHC to reduce heavy drinking. Key outcomes included alcohol consumption, screening, brief interventions and costs in PHC. Predictor measures concerned single versus multiple strategies, type of strategy, duration and physician-only input versus that including mid-level professionals. Standardized mean differences (SMD) were calculated to indicate the impact of implementation strategies on key outcomes. Effect sizes were aggregated using meta-regression models. The 29 included studies were of moderate methodological quality. Strategies had no overall impact on patients' reported alcohol consumption [SMD=0.07; 95% confidence interval (CI)=-0.02 to 0.16], despite improving screening (SMD=0.53; 95% CI=0.28-0.78) and brief intervention delivery (SMD=0.64;95% CI=0.27-1.02). Multi-faceted strategies, i.e. professional and/or organizational and/or patient-orientated strategies, seemed to have strongest effects on patients' alcohol consumption (P<0.05, compared with professional-orientated strategies alone). Regarding SBI delivery, combining professional with patient-orientated implementation strategies had the highest impact (P<0.05). Involving other staff besides physicians was beneficial for screening (P<0.05). To increase delivery of alcohol screening and brief interventions and decrease patients' alcohol consumption, implementation strategies should include a combination of patient-, professional- and organizational-orientated approaches and involve mid-level health professionals as well as physicians. © 2015 Society for the Study of Addiction.

RNA interference: a new strategy in the evolutionary arms race between human control strategies and insect pests.

The relationship between humans and the insect pests of cultivated plants may be considered to be an indirect coevolutionary process, i.e., an arms race. Over time, humans have developed several strategies to minimize the negative impacts of insects on agricultural production. However, insects have made adaptive responses via the evolution of resistance to insecticides, and more recently against Bacillus thuriengiensis. Thus, we need to continuously invest resources in the development of new strategies for crop protection. Recent advances in genomics have demonstrated the possibility of a new weapon or strategy in this war, i.e., gene silencing, which involves blocking the expression of specific genes via mRNA inactivation. In the last decade, several studies have demonstrated the effectiveness of this strategy in the control of different species of insects. However, several technical difficulties need to be overcome to transform this potential into reality, such as the selection of target genes, the concentration of dsRNA, the nucleotide sequence of the dsRNA, the length of dsRNA, persistence in the insect body, and the life stage of the target species where gene silencing is most efficient. This study analyzes several aspects related to the use of gene silencing in pest control and it includes an overview of the inactivation process, as well as the problems that need to be resolved to transform gene silencing into an effective pest control method.

Strategies for improving employee retention.

This article proposes a solution to the perennial problem of talent retention in the clinical laboratory. It includes the presentation of 12 strategies that may be used to significantly improve institutional identity formation and establishment of the psychological contract that employees form with laboratory management. Identity formation and psychological contracting are deemed as essential in helping reduce employee turnover and increase retention. The 12 conversational strategies may be used as a set of best practices for all employees, but most importantly for new employees, and should be implemented at the critical moment when employees first join the laboratory. This time is referred to as "retention on-boarding"--the period of induction and laboratory orientation. Retention on-boarding involves a dialogue between employees and management that is focused on the psychological, practical, cultural, and political dimensions of the laboratory. It is placed in the context of the modern clinical laboratory, which is faced with employing and managing Generation X knowledge workers. Specific topics and broad content areas of those conversations are outlined.

A strategy for evaluating pathway analysis methods.

2017-10-13

Researchers have previously developed a multitude of methods designed to identify biological pathways associated with specific clinical or experimental conditions of interest, with the aim of facilitating biological interpretation of high-throughput data. Before practically applying such pathway analysis (PA) methods, we must first evaluate their performance and reliability, using datasets where the pathways perturbed by the conditions of interest have been well characterized in advance. However, such 'ground truths' (or gold standards) are often unavailable. Furthermore, previous evaluation strategies that have focused on defining 'true answers' are unable to systematically and objectively assess PA methods under a wide range of conditions. In this work, we propose a novel strategy for evaluating PA methods independently of any gold standard, either established or assumed. The strategy involves the use of two mutually complementary metrics, recall and discrimination. Recall measures the consistency of the perturbed pathways identified by applying a particular analysis method to an original large dataset and those identified by the same method to a sub-dataset of the original dataset. In contrast, discrimination measures specificity-the degree to which the perturbed pathways identified by a particular method to a dataset from one experiment differ from those identifying by the same method to a dataset from a different experiment. We used these metrics and 24 datasets to evaluate six widely used PA methods. The results highlighted the common challenge in reliably identifying significant pathways from small datasets. Importantly, we confirmed the effectiveness of our proposed dual-metric strategy by showing that previous comparative studies corroborate the performance evaluations of the six methods obtained by our strategy. Unlike any previously proposed strategy for evaluating the performance of PA methods, our dual-metric strategy does not rely on any ground truth

Women's autonomy and husbands' involvement in maternal health care in Nepal.

Both increasing women's autonomy and increasing husbands' involvement in maternal health care are promising strategies to enhance maternal health care utilization. However, these two may be at odds with each other insofar as autonomous women may not seek their husband's involvement, and involved husbands may limit women's autonomy. This study assessed the relationship between women's autonomy and husbands' involvement in maternal health care. Field work for this study was carried out during September-November 2011 in the Kailali district of Nepal. In-depth interviews and focus group discussions were used to investigate the extent of husbands' involvement in maternal health care. A survey was carried out among 341 randomly selected women who delivered a live baby within one year prior to the survey. The results show that husbands were involved in giving advice, supporting to reduce the household work burden, and making financial and transportation arrangements for the delivery. After adjustment for other covariates, economic autonomy was associated with lower likelihood of discussion with husband during pregnancy, while domestic decision-making autonomy was associated with both lower likelihood of discussion with husband during pregnancy and the husband's presence at antenatal care (ANC) visits. Movement autonomy was associated with lower likelihood of the husband's presence at ANC visits. Intra-spousal communication was associated with higher likelihood of discussing health with the husband during pregnancy, birth preparedness, and the husbands' presence at the health facility delivery. The magnitude and direction of association varied per autonomy dimension. These findings suggest that programs to improve the women's autonomy and at the same time increase the husband's involvement should be carefully planned. Despite the traditional cultural beliefs that go against the involvement of husbands, Nepalese husbands are increasingly entering into the area of maternal

This investigation examined factors affecting patient involvement in consultations to decide local treatment for early breast cancer and the effectiveness of two methods of preconsultation education aimed at increasing patient participation in these discussions. Sixty patients with Stage I or II breast cancer (1) were pretested on their knowledge about breast cancer treatment and optimism for the future, (2) were randomly assigned to one of two methods for preconsultation education: interactive multimedia program or brochure, (3) completed knowledge and optimism measures, (4) consulted with a medical oncologist, radiation oncologist, and general surgeon, and (5) completed self-report measures assessing their involvement in the consultations and control over decision-making. The consultations were audiorecorded and analyzed to identify behavioral indicators of patient involvement (question-asking, opinion-giving, and expressing concern) and physician utterances encouraging patient participation. College-educated patients younger than 65 years of age were more active participants in these consultations than were older, less educated patients. In addition, patients showed more involvement when they interacted with physicians who encouraged and facilitated patient participation. The method of education did not affect patient involvement although patients tended to learn more about breast cancer treatment after using the multimedia program than after reading the brochure. Although patients vary in their expressiveness, physicians may be able to increase patient participation in deciding treatment by using patient-centered behavior. Also, preconsultation education appears to be an effective clinical strategy for helping patients gain an accurate understanding of their treatment options before meeting with physicians.

Prevalence of white spot syndrome virus (WSSV) was determined using polymerase chain reaction (PCR) methodology on DNA extracted from the gills of wild black tiger shrimp Penaeus monodon collected from 7 sampling sites in the Philippines. These 7 sampling sites are the primary sources of spawners and broodstock for hatchery use. During the dry season, WSSV was detected in shrimp from all sites except Bohol, but during the wet season it was not detected in any site except Palawan. None of the WSSV-PCR positive shrimp showed signs of white spots in the cuticle. Prevalence of WSSV showed seasonal variations, i.e. prevalence in dry season (April to May) was higher than in the wet season (August to October). These results suggest that WSSV has already become established in the local marine environment and in wild populations of P. monodon. Thus, broodstock collected during the dry season could serve as the main source of WSSV contamination in shrimp farms due to vertical transmission of the virus in hatcheries.

The research has been conducted to study some technical steps for male germ-plasm from endemic fish species such as some species of Oryzias fish in Indonesia to preserve and propagate through germ cell transplantation technology. For preliminary research, the study was started with germ cell characterization of testes, cryopreservation of TGC and the transplantation of Oryzias celebensis as candidates for surrogate broodstock of Oryzias fish male germ plasm. The data analized included the potential number of TGC as donor, the viability of cryopreserved TGC in two types of cryoprotectans and the survival rate of O.celebensis larvae as recipient after transplantation. The result showed that the average amount of TGC yielded after dissociation was 131000 ± 31349 with 74.2 % viability of TGC each. Cryoprotectan10% DMSO +glucose yielded higher viable of TGC. More than 80 % of O.celebensis larvae survived after transplantation. In conclusion, these preliminary data of O.celebensis as surrogate broodstock candidate will support the application of TGC transplantation technology in Oryzias endemic species.

The study aimed to collect descriptive information on the decision-making processes of adult shoppers around food purchases when young children are present. Anthropological field observations were conducted on adult-child grocery shoppers. Eleven supermarkets in the Minneapolis-St. Paul metropolitan region. A convenience sample (n = 142) of adult-child shoppers at 8 budget and 3 deluxe supermarkets located in diverse urban and suburban areas. Observations registered adult-child interactions over food selections, including parental yielding or refusal strategies and child engagement in shopping. Means and frequencies were calculated for food items considered. In 67 (50.4%) of the total 133 observations, a child initiated a request. Half (55.2%) of the requests were for sweets or snacks. Nearly half (47.8%) of adults yielded to the child's request. Brands and marketing techniques appeared to be a factor in 28.6% of selections. The most frequent adult refusals either provided an explanation or ignored the request. Adults yield to children's requests for sweets and snacks nearly as often as they refuse them. However, effective refusal strategies are used by many adults. Opportunities exist in the grocery store for adults to reinforce young children's interest in food and nutrition.

Public involvement can impact on research, on the public who give advice, on the researchers and the research participants. Evaluating impact is an important part of the research process. Two members of a hospital-based patient research panel and our coordinator have written this paper. Our panel covers a range of rehabilitation and palliative services. These services form the "Therapeutics and Palliative Care Directorate". We describe how we worked collaboratively with hospital staff and co-produced questionnaires to evaluate the impact of our involvement. We compared the different perspectives of the researchers and panel members on our contribution to the research. We present evidence from these different standpoints, including how our panel made a difference. We found we needed to adapt how we collected the views of the researchers and our members to ensure it was meaningful to our group whilst delivering the wider objective of the hospital. A key finding has been how our involvement has extended into other groups, which has identified opportunities for sharing resources and experience, including areas such as cost effectiveness. Our two-person membership of a high level Board of Academics and Senior Clinicians, which oversees the research we contribute to, has resulted in our opinions influencing the heart of the Directorate's research strategy. We have learned the importance of a flexible approach as the Directorate changes, and the demands on us grow. This will continue to help us share our own development, successes and experience and extend the benefits from working this way. Background Reports about the impact of patient and public involvement in research can be improved by involving patients and research staff more collaboratively to co-produce instruments to measure their involvement. This commentary, written by two members of a hospital-based patient panel and their coordinator for its work, describes how we co-produced instruments to evaluate the

While formative workplace based assessment can improve learners' skills, it often does not because the procedures used do not facilitate feedback which is sufficiently specific to scaffold improvement. Provision of pre-formulated strategies to address predicted learning needs has potential to improve the quality and automate the provision of written feedback. To systematically develop, validate and maximise the utility of a comprehensive list of strategies for improvement of consultation skills through a process involving both medical students and their clinical primary and secondary care tutors. Modified Delphi study with tutors, modified nominal group study with students with moderation of outputs by consensus round table discussion by the authors. 35 hospital and 21 GP tutors participated in the Delphi study and contributed 153 new or modified strategies. After review of these and the 205 original strategies, 265 strategies entered the nominal group study to which 46 year four and five students contributed, resulting in the final list of 249 validated strategies. We have developed a valid and comprehensive set of strategies which are considered useful by medical students. This list can be immediately applied by any school which uses the Calgary Cambridge Framework to inform the content of formative feedback on consultation skills. We consider that the list could also be mapped to alternative skills frameworks and so be utilised by schools which do not use the Calgary Cambridge Framework.

Health care among street-involved women: the perpetuation of health inequity.

PubMed

Bungay, Vicky

2013-08-01

I present the findings from a study that explored the experiences and decision making of street-involved women navigating the health care system. Data were drawn from a larger qualitative study situated in a western Canadian inner-city neighborhood that examined the health-management strategies of street-involved women with a history of crack cocaine use. Data were collected over a 17-month period and included ethnographic methods of participant observation, group interviews (n = 57), and in-depth interviews (n = 10). Inductive thematic analysis derived two major themes: power and punishment, and organization and delivery of care. The themes illustrate how women's experiences and decision making were located within a nexus of power relations that operated across women's shared social location as downtown eastsiders. Implications of the findings are discussed in relation to supporting women's efforts and improving health outcomes.

Smart grids-Smat cities "fashion" requires management plans of highly urbanized areas located over the Padanian floodplain, which are prone to diffuse pollution of both lands and urban sectors, mostly after the disasters caused by tremendous alluvial rains in January 2014, when shallow aquifers and agricultural matters could have increase pollution over wide territory. Moreover the urban expansion has affected areas previously used for industrial activity and in some cases such for landfills. When the loss of memory of previous activity prevails after urbanization, with health issues, ethical questions are inevitable, accompanied by social conflicts and economic impacts. The alluvial plains of active tectonic areas - as the Padania Valley - in additions to widespread "anthropogenic pollution" is suffering from widespread "natural pollution" of deep fluid sources - mainly methane - corresponding to areas prone to uprising gaseous brines, along faults. Some of them were partially activated during the 2012 Emilia seismic sequence. This noteworthy seismic sequence engaged discussion about the possible role of gas storages and hydrocarbons production or the simple/exploring drilling activity to trigger typical tectonic seismicity. The paper deepen this troubled communication strategy, their gaps and peculiar geopolicy case histories, to avoid the same strategy, in the future. On the other hand, gas burst or brine-gas-contamination in shallow aquifers, soils and indoor, should be studied by simple and cheap methods, by deepening stratigraphic gaps for the tectonics effects on sedimentation: natural processes should be recalled prior to recall anthropogenic causes, if any. Policy should be more responsible in state clearly the role of research in study infrastructures/processes, also when engaged by private companies, for sites selected by ministries mostly to star research: relevant gaps involves serious confusion in the public as regards responsibility and an exact

Guidelines for management of small adrenal incidentalomas are mutually inconsistent. No cost-effectiveness analysis has been performed to evaluate rigorously the relative merits of these strategies. We constructed a decision-analytic model to evaluate surveillance strategies for <4cm, nonfunctional, benign-appearing adrenal incidentalomas. We evaluated 4 surveillance strategies: none, one-time, annual for 2 years, and annual for 5 years. Threshold and sensitivity analyses assessed robustness of the model. Costs were represented in 2016 US dollars and health outcomes in quality-adjusted life-years. No surveillance has an expected net cost of $262 and 26.22 quality-adjusted life-years. One-time surveillance costs $158 more and adds 0.2 quality-adjusted life-years for an incremental cost-effectiveness ratio of $778/quality-adjusted life-years. The strategies involving more surveillance were dominated by the no surveillance and one-time surveillance strategies less effective and more expensive. Above a 0.7% prevalence of adrenocortical carcinoma, one-time surveillance was the most effective strategy. The results were robust to all sensitivity analyses of disease prevalence, sensitivity, and specificity of diagnostic assays and imaging as well as health state utility. For patients with a < 4cm, nonfunctional, benign-appearing mass, one-time follow-up evaluation involving a noncontrast computed tomography and biochemical evaluation is cost-effective. Strategies requiring more surveillance accrue more cost without incremental benefit. Copyright © 2017 Elsevier Inc. All rights reserved.

Care planning for aggression management in a specialist secure mental health service: An audit of user involvement.

2016-12-01

This paper describes an audit of prevention and management of violence and aggression care plans and incident reporting forms which aimed to: (i) report the compliance rate of completion of care plans; (ii) identify the extent to which patients contribute to and agree with their care plan; (iii) describe de-escalation methods documented in care plans; and (iv) ascertain the extent to which the de-escalation methods described in the care plan are recorded as having been attempted in the event of an incident. Care plans and incident report forms were examined for all patients in men's and women's mental health care pathways who were involved in aggressive incidents between May and October 2012. In total, 539 incidents were examined, involving 147 patients and 121 care plans. There was no care plan in place at the time of 151 incidents giving a compliance rate of 72%. It was documented that 40% of patients had contributed to their care plans. Thematic analysis of de-escalation methods documented in the care plans revealed five de-escalation themes: staff interventions, interactions, space/quiet, activities and patient strategies/skills. A sixth category, coercive strategies, was also documented. Evidence of adherence to de-escalation elements of the care plan was documented in 58% of incidents. The reasons for the low compliance rate and very low documentation of patient involvement need further investigation. The inclusion of coercive strategies within de-escalation documentation suggests that some staff fundamentally misunderstand de-escalation. © 2016 Australian College of Mental Health Nurses Inc.

Gait post-stroke: Pathophysiology and rehabilitation strategies.

PubMed

Beyaert, C; Vasa, R; Frykberg, G E

2015-11-01

We reviewed neural control and biomechanical description of gait in both non-disabled and post-stroke subjects. In addition, we reviewed most of the gait rehabilitation strategies currently in use or in development and observed their principles in relation to recent pathophysiology of post-stroke gait. In both non-disabled and post-stroke subjects, motor control is organized on a task-oriented basis using a common set of a few muscle modules to simultaneously achieve body support, balance control, and forward progression during gait. Hemiparesis following stroke is due to disruption of descending neural pathways, usually with no direct lesion of the brainstem and cerebellar structures involved in motor automatic processes. Post-stroke, improvements of motor activities including standing and locomotion are variable but are typically characterized by a common postural behaviour which involves the unaffected side more for body support and balance control, likely in response to initial muscle weakness of the affected side. Various rehabilitation strategies are regularly used or in development, targeting muscle activity, postural and gait tasks, using more or less high-technology equipment. Reduced walking speed often improves with time and with various rehabilitation strategies, but asymmetric postural behaviour during standing and walking is often reinforced, maintained, or only transitorily decreased. This asymmetric compensatory postural behaviour appears to be robust, driven by support and balance tasks maintaining the predominant use of the unaffected side over the initially impaired affected side. Based on these elements, stroke rehabilitation including affected muscle strengthening and often stretching would first need to correct the postural asymmetric pattern by exploiting postural automatic processes in various particular motor tasks secondarily beneficial to gait.

Parental strategies to help children with phenylketonuria (PKU) cope with feeling different.

PubMed

Zwiesele, Sheila; Bannick, Allison; Trepanier, Angela

2015-08-01

This study assessed feelings of differentness in children with phenylketonuria (PKU) and elicited parental coping strategies. A total of 22 parents of 7- to 12-year-old patients with PKU completed qualitative interviews, which assessed whether they think their children feel different from their peers and identified potential solution strategies. The results showed that most parents indicated their child feels different due to PKU, which is frequently triggered by situations surrounding food. PKU community involvement and educating others about PKU were perceived by parents as useful coping strategies. Talking to children about differences was frequently used but one of the least effective strategies. Extended family, clinicians, and teachers also attempted to help children cope with feeling different with varying degrees of success. We concluded that most parents perceive that their child with PKU feels different and have developed strategies to manage these feelings. However, a subset struggle with helping their child cope and may benefit from assistance from healthcare providers. © 2015 Wiley Periodicals, Inc.

To explore factors impacting on the feasibility of academic and educator roles for consumers of mental health services. The supports required to facilitate these roles from the perspectives of mental health nurse academics and consumer educators/academics will also be explored. Involving consumers in the education of health professionals is becoming more common. Frequently this strategy is viewed as important to influence the attitudes of health professionals towards consumer participation in mental health services. There remains a paucity of research about these roles and the factors which promote and support their feasibility. Qualitative exploratory. In-depth telephone interviews were undertaken with 34 nurse academics and 12 consumer educators or academics. Participants included nurse academics coordinating undergraduate and postgraduate mental health subjects, and consumer academics and educators involved in teaching mental health nursing components. Interviews were 20-45 minutes in duration. Data were analysed thematically. Four subthemes were identified under the broad theme of feasibility and support: Reliability, support, vulnerability and seen to be griping. Significant barriers were identified by nurses and consumers to effective consumer involvement, largely reflecting the impact of mental health challenges. Despite this, there was little evidence of structured support being available to enhance the viability of these positions. Involving consumers in the education of health professionals through teaching, curriculum development, assessment and evaluation, is likely to enhance consumer participation in mental health services and ultimately improve service delivery. This involvement needs to be genuine to be effective. Consumers are often viewed as unreliable, vulnerable and using education to voice their own negative experiences. These issues and lack of support provided pose major barriers to successful roles, strategies to overcome barriers and

There are many recommended language-based strategies for effective communication with persons with dementia. What is unknown is whether effective language-based strategies are also person centered. Accordingly, the objective of this study was to examine whether language-based strategies for effective communication with persons with dementia overlapped with the following indicators of person-centered communication: recognition, negotiation, facilitation, and validation. Conversations (N = 46) between staff-resident dyads were audio-recorded during routine care tasks over 12 weeks. Staff utterances were coded twice, using language-based and person-centered categories. There were 21 language-based categories and 4 person-centered categories. There were 5,800 utterances transcribed: 2,409 without indicators, 1,699 coded as language or person centered, and 1,692 overlapping utterances. For recognition, 26% of utterances were greetings, 21% were affirmations, 13% were questions (yes/no and open-ended), and 15% involved rephrasing. Questions (yes/no, choice, and open-ended) comprised 74% of utterances that were coded as negotiation. A similar pattern was observed for utterances coded as facilitation where 51% of utterances coded as facilitation were yes/no questions, open-ended questions, and choice questions. However, 21% of facilitative utterances were affirmations and 13% involved rephrasing. Finally, 89% of utterances coded as validation were affirmations. The findings identify specific language-based strategies that support person-centered communication. However, between 1 and 4, out of a possible 21 language-based strategies, overlapped with at least 10% of utterances coded as each person-centered indicator. This finding suggests that staff need training to use more diverse language strategies that support personhood of residents with dementia.

Dental education in the United States and Canada is currently experiencing a crisis with respect to faculty recruitment and retention. The major reasons for the status of dental and specialty education are lower salaries and lack of interest. To make up for this deficit in the specialty of periodontology, our current educators need to utilize strategies targeted towards an existing potential teaching resource: the postdoctoral students in periodontology. The intent of this article is to review the current crisis in dental faculty recruitment and retention, show how it affects the specialty of periodontics, and describe how creating a culture of mentoring may facilitate more engagement of periodontal residents in the teaching process during their postdoctoral training. The strategies utilized to develop a culture of mentoring in the Department of Periodontology at Tufts University are presented. They include methodologies to develop and enhance residents' mentoring skills, thereby helping to compensate for the shortage of periodontists involved in academics. Measurement of the mentoring strategy is presented from data obtained from an online survey of third-year predoctoral students' perceptions of their interaction with residents as their clinical instructors. Moreover, the numbers of program alumni engaged in teaching prior to and after the mentoring program was initiated are also presented as an outcome of the mentoring program. Developing a culture of mentoring in postdoctoral periodontology programs can be an important tool to enable individuals to become more involved in the process of teaching and mentoring during their postdoctoral training. This outcome could ameliorate the deficit of periodontists engaged as formal educators. Moreover, development and expansion of a culture of mentoring in a periodontolgy program may encourage recent graduates to become more involved in teaching subsequent to graduation.

Current policy regarding child protection services places increasing demands for providers to engage fathers whose children are involved in the child protection process. This requisite brings to the fore the ongoing challenges that fathers have historically faced in working within these systems. Despite this need, there is little empirical evidence regarding the factors and strategies that impact the engagement of fathers in interventions relevant to child protection services. This comprehensive and systemic review synthesizes the available literature regarding factors and strategies that may foster paternal involvement in the child protection system and their services. We organize the literature concerning paternal engagement in child and family services around an ecological model that examines paternal engagement from individual, family, service provider, program, community, and policy levels. We consider factors and strategies along a continuum of engagement through intent to enroll, enrollment, and retention. This review advances theory by elucidating key factors that foster father engagement. The review also highlights the gaps in the literature and provides strategies for how researchers can address these areas. Future directions in the arenas of practice and policy are discussed.

Reproducibility of Search Strategies Is Poor in Systematic Reviews Published in High-Impact Pediatrics, Cardiology and Surgery Journals: A Cross-Sectional Study

PubMed Central

2016-01-01

Background A high-quality search strategy is considered an essential component of systematic reviews but many do not contain reproducible search strategies. It is unclear if low reproducibility spans medical disciplines, is affected by librarian/search specialist involvement or has improved with increased awareness of reporting guidelines. Objectives To examine the reporting of search strategies in systematic reviews published in Pediatrics, Surgery or Cardiology journals in 2012 and determine rates and predictors of including a reproducible search strategy. Methods We identified all systematic reviews published in 2012 in the ten highest impact factor journals in Pediatrics, Surgery and Cardiology. Each search strategy was coded to indicate what elements were reported and whether the overall search was reproducible. Reporting and reproducibility rates were compared across disciplines and we measured the influence of librarian/search specialist involvement, discipline or endorsement of a reporting guideline on search reproducibility. Results 272 articles from 25 journals were included. Reporting of search elements ranged widely from 91% of articles naming search terms to 33% providing a full search strategy and 22% indicating the date the search was executed. Only 22% of articles provided at least one reproducible search strategy and 13% provided a reproducible strategy for all databases searched in the article. Librarians or search specialists were reported as involved in 17% of articles. There were strong disciplinary differences on the reporting of search elements. In the multivariable analysis, only discipline (Pediatrics) was a significant predictor of the inclusion of a reproducible search strategy. Conclusions Despite recommendations to report full, reproducible search strategies, many articles still do not. In addition, authors often report a single strategy as covering all databases searched, further decreasing reproducibility. Further research is needed

UltraColor: a new gamut-mapping strategy

Many color calibration and enhancement strategies exist for digital systems. Typically, these approaches are optimized to work well with one class of images, but may produce unsatisfactory results for other types of images. For example, a colorimetric strategy may work well when printing photographic scenes, but may give inferior results for business graphic images because of device color gamut limitations. On the other hand, a color enhancement strategy that works well for business graphics images may distort the color reproduction of skintones and other important photographic colors. This paper describes a method for specifying different color mapping strategies in various regions of color space, while providing a mechanism for smooth transitions between the different regions. The method involves a two step process: (1) constraints are applied so some subset of the points in the input color space explicitly specifying the color mapping function; (2) the color mapping for the remainder of the color values is then determined using an interpolation algorithm that preserves continuity and smoothness. The interpolation algorithm that was developed is based on a computer graphics morphing technique. This method was used to develop the UltraColor gamut mapping strategy, which combines a colorimetric mapping for colors with low saturation levels, with a color enhancement technique for colors with high saturation levels. The result is a single color transformation that produces superior quality for all classes of imagery. UltraColor has been incorporated in several models of Kodak printers including the Kodak ColorEase PS and the Kodak XLS 8600 PS thermal dye sublimation printers.

Seed germination strategies vary dramatically among species but relatively little is known about how germination traits correlate with other elements of plant strategy systems. Understanding drivers of germination strategy is critical to our understanding of the evolutionary biology of plant reproduction.We present a novel assessment of seed germination strategies focussing on Australian alpine species as a case study. We describe the distribution of germination strategies and ask whether these are correlated with, or form an independent axis to, other plant functional traits. Our approach to describing germination strategy mimicked realistic temperatures that seeds experience in situ following dispersal. Strategies were subsequently assigned using an objective clustering approach. We hypothesized that two main strategies would emerge, involving dormant or non-dormant seeds, and that while these strategies would be correlated with seed traits (e.g., mass or endospermy) they would be largely independent of vegetative traits when analysed in a phylogenetically structured manner.Across all species, three germination strategies emerged. The majority of species postponed germination until after a period of cold, winter-like temperatures indicating physiological and/or morphological dormancy mechanisms. Other species exhibited immediate germination at temperatures representative of those at dispersal. Interestingly, seeds of an additional 13 species “staggered” germination over time. Germination strategies were generally conserved within families. Across a broad range of ecological traits only seed mass and endospermy showed any correlation with germination strategy when phylogenetic relatedness was accounted for; vegetative traits showed no significant correlations with germination strategy. The results indicate that germination traits correlate with other aspects of seed ecology but form an independent axis relative to vegetative traits. PMID:26528294

Gatekeeping and its impact on father involvement among Black South Africans in rural KwaZulu-Natal.

Involved and caring fatherhood contributes to the health and wellbeing of children, women and men. The corollary is also true - men, women and children are affected when fathers are not involved or supportive of their children. Many factors affect fathers' involvement, including women's attitudes, the history and nature of the relationship between mother and father, and the cultural context. This study explores gatekeeping and its impact on father involvement among Black South Africans in rural KwaZulu-Natal. Among married couples, gatekeeping occurs with respect to childcare and housework through women's attempts to validate their maternal identity according to socially and culturally constructed gender roles. Among unmarried, non-resident parents, women control father-child contact and involvement, with mothers and/or their families either facilitating or inhibiting father involvement. In this context, we found that cultural gatekeeping had a huge impact on father involvement, with the non-payment of inhlawulo or lobola regulating father-child involvement. In a country like South Africa, where there is high non-marital fertility and father-child non-residence, future research, parenting and family programmes should focus on strategies that encourage positive paternal involvement as well as maternal and cultural support for father involvement, regardless of parental relationship and residence status.

Mycobacterium biofilms: factors involved in development, dispersal, and therapeutic strategies against biofilm-relevant pathogens.

Many bacteria can develop biofilm (BF), a multicellular structure largely combining bacteria and their extracellular polymeric substances (EPS). The formation of biofilm results in an alternative existence in which microbes ensure their survival in adverse environments. Biofilm-relevant infections are more persistent, resistant to most antibiotics, and more recalcitrant to host immunity. Mycobacterium tuberculosis, the causative agent of tuberculosis, can develop biofilm, though whether M. tuberculosis can form biofilm within tuberculosis patients has yet to be determined. Here, we summarize the factors involved in the development and dispersal of mycobacterial biofilms, as well as underlying regulatory factors and inhibitors against biofilm to deepen our understanding of their development and to elucidate potential novel modes of action for future antibiotics. Key factors in biofilm formation identified as drug targets represent a novel and promising avenue for developing better antibiotics.

2016-11-01

The economic losses of Porcine Epidemic Diarrhea (PED) and the net benefits of strategies to control the virus are calculated for individual farrow-to-finish herds. A production simulation model that estimates the number of pigs by population cohorts on a weekly basis for a farrow-to-finish farm depending on production parameters is simulated under normal operating conditions and then with an outbreak of PED. The estimated annual costs of a PED outbreak with the closure of the breeding herd as the only intervention is approximately $300,000 for a 700-sow farrow-to-finishing herd. The net returns per sow (hog) fall from $255 ($11.54) to a loss of $174 ($10.68). These losses can be significantly reduced with any of the 16 intervention strategies considered in this study. The most profitable strategy involving front loading of gilts with average feedback of infected material to improve herd immunity, intensive biosecurity protocols and no vaccination costs $27,000 to implement but reduces losses by 10 times this amount. Even the implementation of the least comprehensive strategy, which involves back-loading gilts after the herd reopens and an average feedback practice at a cost of $1000 reduces the losses caused by a PED outbreak by $130,000. Front-loading gilts in combination with herd closure is more cost-effective than back-loading. Despite the extra spending on intensive biosecurity protocols, the overall loss reductions achieved by the intensive biosecurity effort can be significant. Vaccination is the least cost-effective of the intervention practices considered. Even with significant increases in cost or effectiveness in the practices, intervention is justified across all strategies. The spreadsheet model of a farrow-finish hog farm developed in this study can be used to examine changes to the production parameters or to consider other swine disease outbreaks.
