Full Text Available Resource limitations and density dependent releasing of natural enemies during the pest control and integrated pest management will undoubtedly result in nonlinear impulsive control. In order to investigate the effects of those nonlinear control strategies on the successful pest control, we have proposed a pest-natural enemy system concerning integrated pest management with density dependent instant killing rate and releasing rate. In particular, the releasing rate depicts how the number of natural enemy populations released was guided by their current density at the fixed moment. The threshold condition which ensures the existence and global stability of pest-free periodic solution has been discussed first, and the effects of key parameters on the threshold condition reveal that reducing the pulse period does not always benefit pest control; that is, frequent releasing of natural enemies may not be beneficial to the eradication of pests when the density dependent releasing method has been implemented. Moreover, the forward and backward bifurcations could occur once the pest-free periodic solution becomes unstable, and the system could exist with very complex dynamics. All those results confirm that the control actions should be carefully designed once the nonlinear impulsive control measures have been taken for pest management.

Plants defend themselves against attack by natural enemies, and these defenses vary widely across populations. However, whether communities of natural enemies are a sufficiently potent force to maintain polymorphisms in defensive traits is largely unknown. Here, we exploit the genetic resources...... of Arabidopsis thaliana, coupled with 39 years of field data on aphid abundance, to (i) demonstrate that geographic patterns in a polymorphic defense locus (GS-ELONG) are strongly correlated with changes in the relative abundance of two specialist aphids; and (ii) demonstrate differential selection by the two...... aphids on GS-ELONG, using a multigeneration selection experiment. We thereby show a causal link between variation in abundance of the two specialist aphids and the geographic pattern at GS-ELONG, which highlights the potency of natural enemies as selective forces....

Soybean aphid (Aphis glycines Matsumura) (Hemiptera: Aphididae) is a major pest of soybean in northern production regions of North America, and insecticides have been the primary management approach while alternative methods are developed. Knowledge of arthropod natural enemies and their impact on soybean aphid is critical for developing biological control as a management tool. Soybean is a major field crop in South Dakota, but information about its natural enemies and their impact on soybean aphid is lacking. Thus, this study was conducted in field plots in eastern South Dakota during July and August of 2004 and 2005 to characterize foliar-dwelling, arthropod natural enemies of soybean aphid, and it used exclusion techniques to determine impact of natural enemies and ants (Hymenoptera: Formicidae) on soybean aphid densities. In open field plots, weekly soybean aphid densities reached a plateau of several hundred aphids per plant in 2004, and peaked at roughly 400 aphids per plant in 2005. Despite these densities, a relatively high frequency of aphid-infested plants lacked arthropod natural enemies. Lady beetles (Coleoptera: Coccinellidae) were most abundant, peaking at 90 and 52% of all natural enemies sampled in respective years, and Harmonia axyridis Pallas was the most abundant lady beetle. Green lacewings (Neuroptera: Chrysopidae) were abundant in 2005, due mainly to large numbers of their eggs. Abundances of arachnids and coccinellid larvae correlated with soybean aphid densities each year, and chrysopid egg abundance was correlated with aphid density in 2005. Three-week cage treatments of artificially infested soybean plants in 2004 showed that noncaged plants had fewer soybean aphids than caged plants, but abundance of soybean aphid did not differ among open cages and ones that provided partial or total exclusion of natural enemies. In 2005, plants within open cages had fewer soybean aphids than those within cages that excluded natural enemies, and aphid

Full Text Available The article deals with the analysis of publications of British Fascists newspapers 'Action' and 'The Blackshirt' during the Spanish Civil War, 1936-1939. The main directions of image of enemy formation are studied on the example of these papers. Forms of presentation and ways of international problems interpreting by far-right publications are studied. The fascist newspaper Action, The Fascist Week and The Blackshirt spoke from the position of nationalism, Imperial identity, anti-liberalism, anti-Soviet and anti-Semitism. The concept of "communism" in the pages of the fascist press has accumulated the most precisely the image of enemy. Articles and notes shaped confusion between "Soviet", "red" and "Communist". The USSR seemed to be "the warmonger" and the "architect of the Civil war in Spain". The destructive role of Soviet Russia in the conflict was proved in the British fascist press. Soviet Union was accused of seeking to plunge Spain and Europe into anarchy. In British fascist publications trend towards stereotyping and myth-making were noticeable, they were opposed to "Western" civilization (as individualistic and "Eastern", "Communist" (oppressive, traditionalist.

Background Pesticide application is the dominant control method for arthropod pests in broad-acre arable systems. In Australia, organophosphate pesticides are often applied either prophylactically, or reactively, including at higher concentrations, to control crop establishment pests such as false wireworms and earth mite species. Organophosphates are reported to be disruptive to beneficial species, such as natural enemies, but this has not been widely assessed in Australian systems. Neither has the risk that secondary outbreaks may occur if the natural enemy community composition or function is altered. Methods We examine the abundance of ground-dwelling invertebrate communities in an arable field over successive seasons under rotation; barley, two years of wheat, then canola. Two organophosphates (chlorpyrifos and methidathion) were initially applied at recommended rates. After no discernible impact on target pest species, the rate for chlorpyrifos was doubled to elicit a definitive response to a level used at establishment when seedling damage is observed. Invertebrates were sampled using pitfalls and refuge traps throughout the experiments. We applied measures of community diversity, principal response curves and multiple generalised linear modelling techniques to understand the changes in pest and natural enemy communities. Results There was large variability due to seasonality and crop type. Nevertheless, both pest (e.g., mites and aphids) and natural enemy (e.g., predatory beetles) invertebrate communities were significantly affected by application of organophosphates. When the rate of chlorpyrifos was increased there was a reduction in the number of beetles that predate on slug populations. Slugs displayed opposite trends to many of the other target pests, and actually increased in numbers under the higher rates of chlorpyrifos in comparison to the other treatments. Slug numbers in the final rotation of canola resulted in significant yield loss regardless

Wilhelm Reich's self-censorship after his arrest as an enemy alien: the chilling effect of an illegal imprisonment.

After discussing Wilhelm Reich's place in psychoanalysis, the article explores his arrest as an 'enemy alien' in December 1941. Reich's emotional responses to his imprisonment (which was illegal and which lasted nearly a month) are explored. A number of scholars have suggested that many European radical psychoanalysts refrained from sharing their former political ideas once they emigrated to the United States. Following a brief discussion of this pattern of 'silencing,' it is argued that Reich's withholding certain documents from publication was due to a self-imposed censorship, motivated in part by the fear of further governmental interference with his life and work. This fear, however, did not extend to his discussion of his newly developed theory of orgone energy. Copyright © 2014 Institute of Psychoanalysis.

The access and benefit sharing (ABS) regulations from the Convention on Biological Diversity (CBD) for the use of natural resources became an important issue because the biodiversity of developing countries was heavily accessed and unilaterally exploited by pharmaceutical and seed companies. However, natural enemies used for biological control are living and unmodified genetic resources which cannot be patented and have been treated as resources such as drugs, seeds, or other commercial products. Consequently, the ABS requirements have limited not only the use of natural enemies but also the positive effects that scientifically supported biological control strategies have on the society, the environment, and the economy, reducing problems of pesticide residues, water and soil contamination, and non-target effects. During the last several years, the biological control scientific community has faced new and extremely complicated legislation dictated by a high and diverse number of governmental agencies at different levels, making the access to natural resources for biocontrol purposes a rocky road. Society at large should be aware of how the strict ABS regulations affect the use of natural enemies as biological resources to secure food production, food safety, and global environmental protection. We discuss in here the current difficulties derived from CBD for the exchange of natural enemies taking as example the Euro-Mediterranean region, Argentina, and Brazil to demonstrate how long and diverse are the steps to be followed to obtain the required permits for access and exportation/importation of natural enemies. We then argue that the public visibility of biocontrol strategies should be increased and their benefits highlighted in order to persuade legislators for the development of a less bureaucratic, more expedient, and more centralized regulatory frame, greatly favoring the practice and benefits of biological control. We finally propose a general framework in

Whitehouse, T Seth; Sial, Ashfaq A; Schmidt, Jason M

2018-02-08

Natural enemies are valuable components of agroecosystems as they provide biological control services to help regulate pest populations. Promoting biocontrol services can improve sustainability by decreasing pesticide usage, which is a major challenge for the blueberry industry. Our research is the first to compare natural enemy populations in managed (conventional and organic) and unmanaged blueberry systems, in addition to the effects of non-crop habitat. We conducted our study in 10 blueberry orchards during the growing season across the major blueberry producing counties in Georgia, United States. To estimate the spatial distribution of natural enemies, we conducted suction sampling at three locations in each orchard: within the forested border, along the edge of blueberry orchard adjacent to forested border, and within the interior of the blueberry orchard. Natural enemies maintained higher abundance over the season in unmanaged areas when compared with organic or conventional production systems. In the conventional orchards, natural enemies were more abundant in the surrounding non-crop area compared with the interior of the orchard. Populations were more evenly distributed in less intensive systems (organic and unmanaged). Our results indicate spatial structure in natural enemy populations is related to management practice, and less intensive management can retain higher abundance of natural enemies in blueberry systems. Considerations must be made towards promoting ecologically based management practices to sustain natural enemy populations and potentially increase the delivery of biological control services. © The Author(s) 2017.

Enemy-free space and habitat-specific host specialization in a butterfly.

Science.gov (United States)

Wiklund, Christer; Friberg, Magne

The majority of herbivorous insects have relatively specialized food habits. This suggests that specialization has some advantage(s) over generalization. Traditionally, feeding specialization has been thought to be linked to digestive or other food-related physiological advantages, but recent theory suggests that generalist natural enemies of herbivorous insects can also provide a major selective pressure for restricted host plant range. The European swallowtail butterfly Papilio machaon utilizes various plants in the Apiaceae family as hosts, but is an ecological specialist being monophagous on Angelica archangelica in southern Sweden. This perennial monocarp grows in three seaside habitat types: (1) on the barren rocky shore in the absence of any surrounding vegetation, (2) on the rocky shore with some surrounding vegetation, and (3) on species-rich meadows. The rocky shore habitat harbors few invertebrate generalist predators, whereas a number of invertebrate predators abound in the meadowland habitat. Here, we test the importance of enemy-free space for feeding specialization in Papilio machaon by assessing survival of larvae placed by hand on A. archangelica in each of the three habitat types, and by assessing the habitat-specificity of adult female egg-laying behavior by recording the distribution of eggs laid by free-flying adult females among the three habitat types. Larval survival was substantially higher in the rocky shore habitat than in the meadowland and significantly higher on host plants without surrounding vegetation on the rocky shore. Eggs laid by free-flying females were found in all three habitat types, but were significantly more frequent in the rocky shore habitat, suggesting that females prefer to lay eggs in the habitat type where offspring survival is highest. These results show that larval survivorship on the same host plant species can be strongly habitat-specific, and suggest that enemy-free space is an underlying factor that drives

A field trial was performed in a hop yard throughout 2002, 2003 and 2004 in order to determine the within-field distribution of Phorodon humuli (Schrank) (Hemiptera: Aphididae) and its natural enemies. The distribution of P. humuli was directly affected by the position of the hop plants in the garden, with significantly higher concentrations of aphids (p=0.0122 in 2002 and p=0.0006 in 2003) observed along the edge. However, in 2004 the plants located on the marginal plots had similar populations to those on the more inner plots. This can be explained by a higher wind speed which made it more difficult to land on edge plants first. The hop aphid’s main natural enemy was Coccinella septempunctata (Coleoptera: Coccinellidae), whose population was greatest where the aphids were most abundant with a significantly greater number of eggs (p=0.0230) and adults (p=0.0245) in 2003. Lacewing eggs were also frequently observed, with a significantly higher population (p=0.0221 in 2003 and p=0.0046 in 2004) where the aphid numbers were high. The number of winged aphids was greatest towards the margins of the garden in 2003. It is argued that the spatial distribution of the hop aphid and its natural enemies could be used to plan a sampling program and to estimate the population densities of these insects for use in integrated pest management programs.

The attraction of natural enemies towards herbivore-induced plant volatiles is a well-documented phenomenon. However, the majority of published studies are carried under optimal water and nutrient regimes and with just one herbivore. But what happens when additional levels of ecological complexity are added? Does the presence of a second herbivore, microorganisms, and abiotic stress interfere with plant-natural enemy communication? or is communication stable enough to withstand disruption by additional biotic and abiotic factors?Investigating the effects of these additional levels of ecological complexity is key to understanding the stability of tritrophic interactions in natural ecosystems and may aid to forecast the impact of environmental disturbances on these, especially in climate change scenarios, which are often associated with modifications in plant and arthropod species distribution and increased levels of abiotic stress.This review explores the literature on natural enemy attraction to herbivore-induced volatiles when, besides herbivory, plants are challenged by additional biotic and abiotic factors.The aim of this review was to establish the impact of different biotic and abiotic factors on plant-natural enemy communication and to highlight critical aspects to guide future research efforts.

Ohnesorg, Wayne J; Johnson, Kevin D; O'Neal, Matthew E

2009-10-01

Insect predators in North America suppress Aphis glycines Matsumura (Hemiptera: Aphididae) populations; however, insecticides are required when populations reach economically damaging levels. Currently, insecticides used to manage A. glycines are broad-spectrum (pyrethroids and organophosphates), and probably reduce beneficial insect abundance in soybean, Glycine max (L.) Merr. Our goal was to determine whether insecticides considered reduced-risk by the Environmental Protection Agency could protect soybean yield from A. glycines herbivory while having a limited impact on the aphid's natural enemies. We compared three insecticides (imidacloprid, thiamethoxam, and pymetrozine,) to a broad-spectrum insecticide (lamda-cyhalothrin) and an untreated control using two application methods. We applied neonicotinoid insecticides to seeds (imidacloprid and thiamethoxam) as well as foliage (imidacloprid); pymetrozine and lamda-cyhalothrin were applied only to foliage. Foliage-applied insecticides had lower A. glycines populations and higher yields than the seed-applied insecticides. Among foliage-applied insecticides, pymetrozine and imidacloprid had an intermediate level of A. glycines population and yield protection compared with lamda-cyhalothrin and the untreated control. We monitored natural enemies with yellow sticky cards, sweep-nets, and direct observation. Before foliar insecticides were applied (i.e., before aphid populations developed) seed treatments had no observable effect on the abundance of natural enemies. After foliar insecticides were applied, differences in natural enemy abundance were observed when sampled with sweep-nets and direct observation but not with yellow sticky cards. Based on the first two sampling methods, pymetrozine and the foliage-applied imidacloprid had intermediate abundances of natural enemies compared with the untreated control and lamda-cyhalothrin.

Susceptibility of natural enemies of pests of agriculture to commonly applied insecticides in Honduras

1999-01-01

Insecticides are commonly used by Honduran farmers to control pest insects in agricultural crops such as corn, melons and tomatoes. However, the insecticides have the potential for toxicity to the natural enemies of the pest insects also. Therefore, efforts are being made to identify insecticides which, when used within the Inegerated Pest Management (IPM) programme, are selectively more toxic to the pest insects than their natural enemies. A number of selected chemical insecticides and a biological insecticide (NPV) were tested in three different tests to determine toxicity to two beneficial insects: Telenomus remus Nixon (Hymenoptera: Scelionidae) and Chrysoperla carnea Steph. (Neuroptera: Chrysopidae). All insecticides were toxic to T. remus which suffered high mortality. There was no significant difference in mortality of the insect due to the method of exposure to the insecticides. There were some differences in the toxicity of the insecticides to C. carnea, and abamectin, bifenthrin, cypermethrin, diafenthiuron, imidacloprid and fenpropathrin were relatively less toxic and could be used in IPM for the control of pest insects.

Full Text Available The woodwasp Sirex noctilio Fabricius (Hymenoptera: Siricidae was introduced in Brazil in 1988 and became the main pest in pine plantations. It has spread to about 1.000.000 ha, at different population levels, in the states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo and Minas Gerais. Control is done mainly by using a nematode, Deladenus siricidicola Bedding (Nematoda: Neothylenchidae. The evaluation of the efficiency of natural enemies has been difficult because there are no appropriate sampling systems. This study tested a hierarchical sampling system to define the sample size to monitor the S. noctilio population and the efficiency of their natural enemies, which was found to be perfectly adequate.

Fairuz, K.; Idris, A. G.; Syahrizan, S.; Hatijah, K.

2018-04-01

Malacca has committed to be a green technology state by the year 2020. Agriculture is one of the main industries that have been highlighted to achieve this goal especially rice farming activities. Some limitations for this issue have restricted the accomplishment of the plan including pesticide usage among rice farmers. The use of chemicals in rice field need to be reduced significantly in order to support the goal. One of the indicators to the successfulness of pesticide reduction is the increasing numbers of natural enemies' species abundance and population in the rice field. Natural enemies were important to regulate pest populations in rice field naturally. Farmers' readiness to participate in this issue is very important to ensure the successfulness. The level of readiness of farmers' community will determine whether they are ready or not to execute the plan. Unfortunately, such information in rice farmers' community was not properly measured. Thus this study was aimed to assess the readiness level of rice farmers' community to change in order to enhance natural enemies in their rice field. This study was adapting the CR model as its theoretical framework. Three rice farming area in Malacca were involved in this study namely, Jasin, Melaka Tengah and Alor Gajah. Questionnaires were used as major instrument and were randomly distributed to 224 farmers. Data collected were tested for their reliability, significance and level of readiness. Knowledge of issue, knowledge of effort and resources dimensions were found influencing the readiness dimension significantly, whilst the attitude and leadership dimensions were not. Generally, the level of readiness for farmers' community in Malacca was found in the sixth or initial stage, where some of them initially have started to practice a few related activities to enhance the natural enemies' population in their rice field. Continuous support and assistant from the leaders and local authorities are crucially needed in

The enemy release hypothesis is frequently invoked to explain invasion by nonnative species, but studies focusing on the influence of enemies on natural plant range expansion due to climate change remain scarce. We combined multiple approaches to study the influence of plant-enemy interactions on the upper elevational range limit of sugar maple (Acer saccharum) in southeastern Québec, Canada, where a previous study had demonstrated intense seed predation just beyond the range limit. Consistent with the hypothesis of release from natural enemies at the range limit, data from both natural patterns of regeneration and from seed and seedling transplant experiments showed higher seedling densities at the range edge than in the core of the species' distribution. A growth chamber experiment manipulating soil origin and temperature indicated that this so-called "happy edge" was not likely caused by temperature (i.e., the possibility that climate warming has made high elevation temperatures optimal for sugar maple) or by abiotic soil factors that vary along the elevational gradient. Finally, an insect-herbivore-exclusion experiment showed that insect herbivory was a major cause of seedling mortality in the core of sugar maple's distribution, whereas seedlings transplanted at or beyond the range edge experienced minimal herbivory (i.e., enemy release). Insect herbivory did not completely explain the high levels of seedling mortality in the core of the species' distribution, suggesting that seedlings at or beyond the range edge may also experience release from pathogens. In sum, while some effects of enemies are magnified beyond range edges (e.g., seed predation), others are dampened at and beyond the range edge (e.g., insect herbivory), such that understanding the net outcome of different biotic interactions within, at and beyond the edge of distribution is critical to predicting species' responses to global change. © 2016 by the Ecological Society of America.

Ophiocordyceps sinensis (syn. Cordyceps sinensis), well known as DongChongXiaCao (DCXC), is one of the most valuable traditional Chinese medicinal species. In this article, we provide a systematic review of natural enemies and diseases encountered in artificial cultivation of DCXC. Unfortunately, DCXC has been endangered over the past decades due to overharvesting and a worsening ecological environment. Therefore, the artificial cultivation of DCXC has been extensively investigated in recent years. Complete indoor artificial cultivation and semi-field cultivation are the two most common strategies used to cultivate DCXC. However, cultured DCXCs are often attacked by various natural enemies and diseases, which have resulted in substantial loss of the valuable medicinal resource. In this study, we have summarized the species of natural enemies and types of diseases confronted by DCXC. Twenty reported natural enemy species are categorized into four classes, one of which is reported for the first time in this study. Moreover, six microbial pathogens are also discussed. The recapitulation of the natural enemies and diseases in DCXC artificial cultivation not only promote the development of integrated pest management of DCXC cultivation but also provide important information to help preserve and develop this valuable resource.

This paper studied the effects of triazophos, shachongshuang, abamectin, and Bt + imidacloprid on the insect pest-natural enemy community in early rice fields in the Yangtze-Huaihe region of Anhui Province. The results showed that all of the test insecticides had significant effects in controlling the growth of major insect pest populations. The average value of insect pest-natural enemy community diversity under effects of triazophos, shachongshuang, abamectin, and Bt + imidacloprid was 1.545, 1.562, 1.691 and 1.915, respectively, while that in control plot was 1.897. After two weeks of applying insecticides, the plots applied with shachongshuang and abamectin had a similar composition of insect pest-natural enemy community, but the community composition was significantly different between the plots applied with triazophos and Bt + imidacloprid. From the viewpoints of community stability and pest control, Bt + imidacloprid had the best effect, and shachongshuang and abamectin were better than triazophos.

Full Text Available The importance of mutualism is receiving more attention in community ecology. In this study, the fire ant Solenopsis invicta was found to take advantage of the shelters constructed by the leaf roller Sylepta derogata to protect mealybugs (Phenacoccus solenopsis against their natural enemies. This protective effect of fire ant tending on the survival of mealybugs in shelters was observed when enemies and leaf rollers were simultaneously present. Specifically, fire ants moved the mealybugs inside the shelters produced by S. derogata on enemy-infested plants. Compared with that in plants without ants, the survival of mealybugs in shelters in the presence of natural enemies in plants with ants markedly improved. Both the protection of ants and the shelters provided by leaf rollers did not affect the survival of mealybugs in the absence of enemies in plants. Ants and leaf rollers significantly improved the survival of mealybugs in predator-infested plants, whereas no such improvement was observed in parasitoid-infested ones.

Genetic variation in plant volatile emission does not result in differential attraction of natural enemies in the field.

Science.gov (United States)

Wason, Elizabeth L; Hunter, Mark D

2014-02-01

Volatile organic chemical (VOC) emission by plants may serve as an adaptive plant defense by attracting the natural enemies of herbivores. For plant VOC emission to evolve as an adaptive defense, plants must show genetic variability for the trait. To date, such variability has been investigated primarily in agricultural systems, yet relatively little is known about genetic variation in VOCs emitted by natural populations of native plants. Here, we investigate intraspecific variation in constitutive and herbivore-induced plant VOC emission using the native common milkweed plant (Asclepias syriaca) and its monarch caterpillar herbivore (Danaus plexippus) in complementary field and common garden greenhouse experiments. In addition, we used a common garden field experiment to gauge natural enemy attraction to milkweed VOCs induced by monarch damage. We found evidence of genetic variation in the total constitutive and induced concentrations of VOCs and the composition of VOC blends emitted by milkweed plants. However, all milkweed genotypes responded similarly to induction by monarchs in terms of their relative change in VOC concentration and blend. Natural enemies attacked decoy caterpillars more frequently on damaged than on undamaged milkweed, and natural enemy visitation was associated with higher total VOC concentrations and with VOC blend. Thus, we present evidence that induced VOCs emitted by milkweed may function as a defense against herbivores. However, plant genotypes were equally attractive to natural enemies. Although milkweed genotypes diverge phenotypically in their VOC concentrations and blends, they converge into similar phenotypes with regard to magnitude of induction and enemy attraction.

Release from natural enemies is often cited as a key factor for understanding the success of invasive plant species in novel environments. However, with time invasive species will accumulate native enemies in their invaded range, with factors such as spread distance from the site of introduction, climate and leaf-level traits potentially affecting enemy acquisition rates. However, the influence of such factors is difficult to assess without examining enemy attack across the entire species' range. We tested the significance of factors associated with range expansion (distance from source population and maximum population density), climatic variables (annual temperature and rainfall) and leaf-level traits [specific leaf area (SLA) and foliar nitrogen concentration] in explaining variation in enemy damage across multiple populations of two coastal invasive plants (Gladiolus gueinzii Kunze and Hydrocotyle bonariensis Lam.) along their entire introduced distribution in eastern Australia. We found that for H. bonariensis, amount of foliar damage increased with distance from source population. In contrast, for G. gueinzii, probability and amount of foliar damage decreased with decreasing temperature and increasing rainfall, respectively. Our results show that patterns of enemy attack across species' ranges are complex and cannot be generalised between species or even range edges.

Urban warming trumps natural enemy regulation of herbivorous pests.

Science.gov (United States)

Dale, Adam G; Frank, Steven D

Trees provide ecosystem services that counter negative effects of urban habitats on human and environmental health. Unfortunately, herbivorous arthropod pests are often more abundant on urban than rural trees, reducing tree growth, survival, and ecosystem services. Previous research where vegetation complexity was reduced has attributed elevated urban pest abundance to decreased regulation by natural enemies. However, reducing vegetation complexity, particularly the density of overstory trees, also makes cities hotter than natural habitats. We ask how urban habitat characteristics influence an abiotic factor, temperature, and a biotic factor, natural enemy abundance, in regulating the abundance of an urban forest pest, the gloomy scale, (Melanaspis tenebricosa). We used a map of surface temperature to select red maple trees (Acer rubrum) at warmer and cooler sites in Raleigh, North Carolina, USA. We quantified habitat complexity by measuring impervious surface cover, local vegetation structural complexity, and landscape scale vegetation cover around each tree. Using path analysis, we determined that impervious surface (the most important habitat variable) increased scale insect abundance by increasing tree canopy temperature, rather than by reducing natural enemy abundance or percent parasitism. As a mechanism for this response, we found that increasing temperature significantly increases scale insect fecundity and contributes to greater population increase. Specifically, adult female M. tenebricosa egg sets increased by approximately 14 eggs for every 1°C increase in temperature. Climate change models predict that the global climate will increase by 2–3°C in the next 50–100 years, which we found would increase scale insect abundance by three orders of magnitude. This result supports predictions that urban and natural forests will face greater herbivory in the future, and suggests that a primary cause could be direct, positive effects of warming on herbivore

Taking the question of why Clint Eastwood made two movies as her point of departure, film scholar Rikke Schubart explores the construction of “us” and “them” in Letters From Iwo Jima. Rather than portray American soldiers as “us” and Japanese soldiers as “them,” the film presents both groups...... of soldiers as equally humane and capable of doing both good and evil. The enemy is not a nation, that is neither the Japanese nor the Americans, but the blind idea of nationalism. In a present day perspective, the film represents a new ethical and global awareness of a conflict between a transnational...... humanism and nationalism in the American war film. Schubart thus argues that Eastwood should be interpreted as a “minor utopian,” an expression coined by historian Jay Winter in his Dreams of Peace and Freedom (2006)....

No evidence of enemy release in pathogen and microbial communities of common wasps (Vespula vulgaris in their native and introduced range.

Directory of Open Access Journals (Sweden)

Philip J Lester

Full Text Available When invasive species move to new environments they typically experience population bottlenecks that limit the probability that pathogens and parasites are also moved. The invasive species may thus be released from biotic interactions that can be a major source of density-dependent mortality, referred to as enemy release. We examined for evidence of enemy release in populations of the common wasp (Vespula vulgaris, which attains high densities and represents a major threat to biodiversity in its invaded range. Mass spectrometry proteomic methods were used to compare the microbial communities in wasp populations in the native (Belgium and England and invaded range (Argentina and New Zealand. We found no evidence of enemy release, as the number of microbial taxa was similar in both the introduced and native range. However, some evidence of distinctiveness in the microbial communities was observed between countries. The pathogens observed were similar to a variety of taxa observed in honey bees. These taxa included Nosema, Paenibacillus, and Yersina spp. Genomic methods confirmed a diversity of Nosema spp., Actinobacteria, and the Deformed wing and Kashmir bee viruses. We also analysed published records of bacteria, viruses, nematodes and fungi from both V. vulgaris and the related invader V. germanica. Thirty-three different microorganism taxa have been associated with wasps including Kashmir bee virus and entomophagous fungi such as Aspergillus flavus. There was no evidence that the presence or absence of these microorganisms was dependent on region of wasp samples (i.e. their native or invaded range. Given the similarity of the wasp pathogen fauna to that from honey bees, the lack of enemy release in wasp populations is probably related to spill-over or spill-back from bees and other social insects. Social insects appear to form a reservoir of generalist parasites and pathogens, which makes the management of wasp and bee disease difficult.

The relationship between crop richness and predator-prey interactions as they relate to pest-natural enemy systems is a very important topic in ecology and greatly affects biological control services. The effects of crop arrangement on predator-prey interactions have received much attention as the basis for pest population management. To explore the internal mechanisms and factors driving the relationship between crop richness and pest population management, we designed an experimental model system of a microlandscape that included 50 plots and five treatments. Each treatment had 10 repetitions in each year from 2007 to 2010. The results showed that the biomass of pests and their natural enemies increased with increasing crop biomass and decreased with decreasing crop biomass; however, the effects of plant biomass on the pest and natural enemy biomass were not significant. The relationship between adjacent trophic levels was significant (such as pests and their natural enemies or crops and pests), whereas non-adjacent trophic levels (crops and natural enemies) did not significantly interact with each other. The ratio of natural enemy/pest biomass was the highest in the areas of four crop species that had the best biological control service. Having either low or high crop species richness did not enhance the pest population management service and lead to loss of biological control. Although the resource concentration hypothesis was not well supported by our results, high crop species richness could suppress the pest population, indicating that crop species richness could enhance biological control services. These results could be applied in habitat management aimed at biological control, provide the theoretical basis for agricultural landscape design, and also suggest new methods for integrated pest management.

Evolutionary dynamics of interactions between plants and their enemies: comparison of herbivorous insects and pathogens.

Science.gov (United States)

Wininger, Kerry; Rank, Nathan

2017-11-01

Plants colonized land over 400 million years ago. Shortly thereafter, organisms began to consume terrestrial plant tissue as a nutritional resource. Most plant enemies are plant pathogens or herbivores, and they impose natural selection for plants to evolve defenses. These traits generate selection pressures on enemies. Coevolution between terrestrial plants and their enemies is an important element of the evolutionary history of both groups. However, coevolutionary studies of plant-pathogen interactions have tended to focus on different research topics than plant-herbivore interactions. Specifically, studies of plant-pathogen interactions often adopt a "gene-for-gene" conceptual framework. In contrast, studies of plants and herbivores often investigate escalation or elaboration of plant defense and herbivore adaptations to overcome it. The main exceptions to the general pattern are studies that focus on small, sessile herbivores that share many features with plant pathogens, studies that incorporate both herbivores and pathogens into a single investigation, and studies that test aspects of Thompson's geographic mosaic theory for coevolution. We discuss the implications of these findings for future research. © 2017 New York Academy of Sciences.

Reduced risk insecticides to control scale insects and protect natural enemies in the production and maintenance of urban landscape plants.

Science.gov (United States)

Frank, Steven D

2012-04-01

Armored scale insects are among the most difficult to manage and economically important arthropod pests in the production and maintenance of urban landscape plants. This is because of morphological traits that protect them from contact insecticides. I compared initial and season-long control of euonymus scale, Unaspis euonymi Comstock (Hemiptera: Diaspidae), by reduced-risk insecticides (insect growth regulators [IGRs], neonicotinoids, spirotetramat) to determine if they controlled scale as well as more toxic insecticides such as the organophosphate, acephate, and pyrethroid, bifenthrin. I also evaluated how these insecticides affected natural enemy abundance on experimental plants and survival when exposed to insecticide residue. All insecticides tested reduced first generation euonymus scale abundance. In 2009, reinfestation by second generation euonymus scale was highest on plants treated with acetamiprid and granular dinotefuran. In 2010, systemic neonicotinoids and spirotetramat prevented cottony cushion scale infestation 133 d after treatment whereas scale readily infested plants treated with bifenthrin and horticultural oil. Encarsia spp. and Cybocephalus spp. abundance was related to scale abundance. These natural enemies were generally less abundant than predicted by scale abundance on granular dinotefuran treated plants and more abundant on granular thiamethoxam treated plants. Bifenthrin residue killed 90-100% of O. insidiosus and E. citrina within 24 h. My results indicate that reduced risk insecticides can provide season-long scale control with less impact on natural enemies than conventional insecticides. This could have economic and environmental benefits by reducing the number of applications necessary to protect nursery and landscape plants from scale.

Wheat aphid (Hemiptera: Aphididae) is one of the major pests of winter wheat and has posed a significant threat to winter wheat production in China. Although neonicotinoid insecticidal seed treatments have been suggested to be a control method, the season-long efficacy on pests and the impact on their natural enemies are still uncertain. Experiments were conducted to determine the efficacy of imidacloprid and clothianidin on the control of aphids, the number of their natural enemies and the emergence rate and yield of wheat during 2011-2014. Imidacloprid and clothianidin seed treatments had no effect on the emergence rate of winter wheat and could prevent yield losses and wheat aphid infestations throughout the winter wheat growing season. Furthermore, their active ingredients were detected in winter wheat leaves up to 200 days after sowing. Imidacloprid and clothianidin seed treatments had no adverse effects on ladybirds, hoverflies or parasitoids, and instead increased the spider-aphid ratios. Wheat seeds treated with imidacloprid and clothianidin were effective against wheat aphids throughout the winter wheat growing season and reduced the yield loss under field conditions. Imidacloprid and clothianidin seed treatments may be an important component of the integrated management of wheat aphids on winter wheat. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

Impact of neonicotinoid insecticides on natural enemies in greenhouse and interiorscape environments.

Cloyd, Raymond A; Bethke, James A

2011-01-01

The neonicotinoid insecticides imidacloprid, acetamiprid, dinotefuran, thiamethoxam and clothianidin are commonly used in greenhouses and/or interiorscapes (plant interiorscapes and conservatories) to manage a wide range of plant-feeding insects such as aphids, mealybugs and whiteflies. However, these systemic insecticides may also be harmful to natural enemies, including predators and parasitoids. Predatory insects and mites may be adversely affected by neonicotinoid systemic insecticides when they: (1) feed on pollen, nectar or plant tissue contaminated with the active ingredient; (2) consume the active ingredient of neonicotinoid insecticides while ingesting plant fluids; (3) feed on hosts (prey) that have consumed leaves contaminated with the active ingredient. Parasitoids may be affected negatively by neonicotinoid insecticides because foliar, drench or granular applications may decrease host population levels so that there are not enough hosts to attack and thus sustain parasitoid populations. Furthermore, host quality may be unacceptable for egg laying by parasitoid females. In addition, female parasitoids that host feed may inadvertently ingest a lethal concentration of the active ingredient or a sublethal dose that inhibits foraging or egg laying. There are, however, issues that require further consideration, such as: the types of plant and flower that accumulate active ingredients, and the concentrations in which they are accumulated; the influence of flower age on the level of exposure of natural enemies to the active ingredient; the effect of neonicotinoid metabolites produced within the plant. As such, the application of neonicotinoid insecticides in conjunction with natural enemies in protected culture and interiorscape environments needs further investigation.

Full Text Available The main cause of Schmitt’s and Kojève’s friendship, and consequently, their correspondence, lies in their common affinity for philosophy of Hegel. When they began corresponding in 1955, Schmitt was something of an academic pariah; in 1933, the legal scholar had joined the Nazi Party, publicly declared his anti-Semitism, was later interrogated (but not charged at Nuremberg, and retired from his post at the University of Berlin in 1946. After his famous lectures on Hegel’s Phenomenology ended in 1939, Kojève joined the Resistance. At the end of the World II War, he wound up in the French ministry of economic affairs, where he worked until his death in 1968. This text is written on the margins of two letters, one written on 14.XII.1955. by Schmitt and the other, Kojève’s answer, dated on 4.I.1956. The subject of those two letters is the interpretation of the enemy in philosophy of Hegel. .

A field investigation was conducted on the spatial distributions of Sitobion avenae and its main natural enemies under wheat-oilseed rape intercropping and methyl salicylate application. With the development of wheat plant, an alternation from aggregation to uniform was observed in the spatial distribution of S. avenae under the intercropping and methyl salicylate application, being more obvious under the interaction of the two practices. The spatial distribution of S. avenae natural enemies was in accordance with that of the aphid. These results could be used for the reference of sampling investigation and forecast of wheat aphid and its natural enemies in field.

Efficient chemical control is achieved when insecticides are active against insect pests and safe to natural enemies. In this study, the toxicity of 17 insecticides to the sweetpotato whitefly, Bemisia tabaci (Gennadius), and the selectivity of seven insecticides to natural enemies of this insect pest were evaluated. To determine the insecticide toxicity, B. tabaci adults were exposed to abamectin, acephate, acetamiprid, cartap, imidacloprid, malathion, methamidophos, bifenthrin, cypermethrin, deltamethrin, esfenvalerate, fenitrothion, fenpropathrin, fenthion, phenthoate, permethrin and trichlorphon at 50 and 100% of the field rate (FR), and to water (untreated control). To determine the insecticide selectivity, adults of Encarsia sp., Acanthinus sp., Discodon sp. and Lasiochilus sp. were exposed to abamectin, acephate, acetamiprid, cartap, imidacloprid, malathion and methamidophos at 50 and 100% FR, and to water. Groups of each insect species were exposed to kale leaves preimmersed in each treatment under laboratory conditions. Mortality of exposed individuals was recorded 24 h after treatment. Cartap and imidacloprid at 50 and 100% FR and abamectin and acetamiprid at 100% FR showed insecticidal activity to B. tabaci adults. Abamectin at 50 and 100% FR was the least insecticidal compound to the natural enemies Acanthinus sp., Discodon sp. and Lasiochilus sp. The present results suggest that abamectin at 100% FR may decrease B. tabaci field populations but can still be harmless to predators. Implications of these results within an integrated pest management context are discussed. Copyright (c) 2007 Society of Chemical Industry.

An acaricidal effect of lime sulfur has not been demonstrated for Polyphagotarsonemus latus. However, lime sulfur can cause toxicity to natural enemies and to host plants. In this study, the toxicity of different concentrations of lime sulfur to P. latus, to the predatory mite Amblyseius herbicolus and to the predatory insect Chrysoperla externa was evaluated. Additionally, the phytotoxicity of lime sulfur to two P. latus hosts, chili pepper and physic nut plants, was determined. Lime sulfur at a concentration of 9.5 mL L(-1) restrained P. latus population growth. However, this concentration was deleterious to natural enemies. The predatory mite A. herbicolus showed a negative value of instantaneous growth rate, and only 50% of the tested larvae of C. externa reached adulthood when exposed to 10 mL L(-1) . Physic nut had severe injury symptoms when sprayed with all tested lime sulfur concentrations. For chili pepper plants, no phytoxicity was observed at any tested concentration. Lime sulfur might be used for P. latus control on chili pepper but not on physic nut owing to phytotoxicity. Care should be taken when using lime sulfur in view of negative effects on natural enemies. Selective lime sulfur concentration integrated with other management tactics may provide an effective and sustainable P. latus control on chili pepper. © 2012 Society of Chemical Industry.

Discourses of Dehumanization: Enemy Construction and Canadian Media Complicity in the Framing of the War on Terror

Directory of Open Access Journals (Sweden)

Erin Steuter

2009-01-01

Full Text Available This paper examines the Canadian news media’s coverage of the wars in Afghanistan and Iraq. In particular, Canadian newspaper headlines are examined for the way in which an image of the “enemy” is constructed and framed in dominant media discourse. An analysis of the data reveals a pattern of dehumanizing language applied to enemy leaders as well as Arab and Muslim citizens at large in the media’s uncritical reproduction of metaphors that linguistically frame the enemy in particular ways. Particularly, the paper argues that the Canadian media have participated in mediating constructions of Islam and Muslims, mobilizing familiar metaphors in representations that fabricate an enemy-Other who is dehumanized, de-individualized, and ultimately expendable. This dehumanizing language takes the form of animal imagery that equates and reduces human actions with sub-human behaviours. This paper argues that the repeated use of animal metaphors by monopoly media institutions constitute motivated representations that have ideological importance. The consequences of these representations are more than rhetorical, setting the stage for racist backlash, prisoner abuse and even genocide.

Mechanisms of symbiont-conferred protection against natural enemies: an ecological and evolutionary framework.

Science.gov (United States)

Gerardo, Nicole M; Parker, Benjamin J

2014-10-01

Many vertically-transmitted microbial symbionts protect their insect hosts from natural enemies, including host-targeted pathogens and parasites, and those vectored by insects to other hosts. Protection is often achieved through production of inhibiting toxins, which is not surprising given that toxin production mediates competition in many environments. Classical models of macroecological interactions, however, demonstrate that interspecific competition can be less direct, and recent research indicates that symbiont-protection can be mediated through exploitation of limiting resources, and through activation of host immune mechanisms that then suppress natural enemies. Available data, though limited, suggest that effects of symbionts on vectored pathogens and parasites, as compared to those that are host-targeted, are more likely to result from symbiont activation of the host immune system. We discuss these different mechanisms in light of their potential impact on the evolution of host physiological processes. Copyright © 2014 Elsevier Inc. All rights reserved.

Guantánamo Bay: A Reflection On The Legal Status And Rights Of ‘Unlawful Enemy Combatants’

Directory of Open Access Journals (Sweden)

Terry D. Gill

2005-07-01

Full Text Available The United States administration’s policy of detaining ‘unlawful enemy combatants’ at the United States military base in Guantánamo Bay falls short of international and domestic law standards. The problem in the authors’ view is not that the United States has decided to designate those captured on the battlefield in Afghanistan as ‘unlawful combatants’ who (allegedly fall outside the scope of international humanitarian law. International humanitarian law has long recognized the existence of such a category. The problem is rather that international humanitarian law has been sporadically and selectively applied and in many respects has been ignored or violated with respect to the detainees held in Guantánamo and elsewhere within the context of the ‘war on terror’. In its recent judgements in Hamdi v. Rumsfeld, Rumsfeld v. Bush and Rasul v. Bush the United States Supreme Court has not passed an unambiguous and clear judgement on the United States policy towards unlawful enemy combatants. The Court may have rejected the executive’s claim that it has the authority to incarcerate people suspected of terrorist connections without any judicial review, the three decisions have not imposed on the executive a clear framework governing the detention of alleged terrorists. The Court has upheld the government’s power to hold ‘enemy combatants’ according to standards that fall short of the requirements of the Geneva Conventions. Moreover, the due process protection granted to those challenging their status as’ enemy combatant’ is so deferential to the executive that it could render review virtually insignificant.

Single-particle states vs. collective modes: friends or enemies ?

Science.gov (United States)

Otsuka, T.; Tsunoda, Y.; Togashi, T.; Shimizu, N.; Abe, T.

2018-05-01

The quantum self-organization is introduced as one of the major underlying mechanisms of the quantum many-body systems. In the case of atomic nuclei as an example, two types of the motion of nucleons, single-particle states and collective modes, dominate the structure of the nucleus. The collective mode arises as the balance between the effect of the mode-driving force (e.g., quadrupole force for the ellipsoidal deformation) and the resistance power against it. The single-particle energies are one of the sources to produce such resistance power: a coherent collective motion is more hindered by larger spacings between relevant single particle states. Thus, the single-particle state and the collective mode are "enemies" against each other. However, the nuclear forces are rich enough so as to enhance relevant collective mode by reducing the resistance power by changing single-particle energies for each eigenstate through monopole interactions. This will be verified with the concrete example taken from Zr isotopes. Thus, the quantum self-organization occurs: single-particle energies can be self-organized by (i) two quantum liquids, e.g., protons and neutrons, (ii) monopole interaction (to control resistance). In other words, atomic nuclei are not necessarily like simple rigid vases containing almost free nucleons, in contrast to the naïve Fermi liquid picture. Type II shell evolution is considered to be a simple visible case involving excitations across a (sub)magic gap. The quantum self-organization becomes more important in heavier nuclei where the number of active orbits and the number of active nucleons are larger.

«Unclear Enemy»: Why the Guerrilla War in France in 1814 Failed

Full Text Available Abstract: Author of the article analyzes the reasons of the fail of Napoleon’s attempts to set the guerrilla war in France during the campaign of 1814. While the forces of anti-Napoleonic coalition were standing near the border of France, Napoleon did his best to recruit his new army. But the human resources of France were exhausted, and that’s why Napoleon decided to set the guerrillia. But all his proclamations and even his orders were disobeyed - French people were too tired of incessant war, and Napoleon again decided to gain his goals on the battlefield. Besides author shows great efforts of Russian headquarters to avoid the guerrilla war. Alexander I and his allies in theirs proclamations declared that they were fighting only with Napoleon, but not with the French nation. That tactic gave a brilliant result and helped to avoid the patriotic uplift in France in 1814. In this propagandistic war Napoleon was defeated and that cost him his throne. The reasons of Napoleon’s fail, firstly, was the unclear image of the enemy. French emperor didn’t manage to unite French nation against the rival. On the contrary the French Emperor, his enemies managed (in their proclamations and personal conversations to persuade the French people, that the allies had one enemy - the Emperor Napoleon, not the French nation, and the ultimate goal of war - to set peace on the European continent. That was exactly how the allies did set the disunity between Napoleon and his people. Ultimately, the combination of these factors was the reason that a guerrilla war never broke out in France.

In order to explore the effects of wheat-oilseed rape intercropping in combining with methyl salicylate (MeSA) release on Sitobion avenae and its main natural enemies, a field experiment was conducted at the Tai'an Experimental Station of Shandong Agricultural University in East China from October 2008 to June 2010 to study the temporal dynamics of S. avenae and its main natural enemies as well as the ecological control effect on the aphid. In the plots of intercropping combined with MeSA release, the S. avenae apterae population reached a peak about 12 d in advance of the control, but the peak value was significantly lower than that of the control. The average annual number of S. avenae apterae per 100 wheat tillers decreased in the order of wheat monoculture > wheat-oilseed rape intercropping > MeSA release > wheat-oilseed rape intercropping combined with MeSA release. Moreover, the total number of ladybeetles was the highest in the plots of intercropping combined with MeSA release. The population densities of aphid parasitoids reached a peak about 10 d in advance of the control, which could play a significant role in controlling S. avenae at the filling stage of wheat. Taking the biological control index (BCI) as a quantitative indicator, and with the ladybeetles and parasitoids as the dominant control factors in fields, it was observed that wheat-oilseed rape intercropping combined with MeSA release could suppress the population increase of S. avenae apterae effectively from the heading to filling stages of wheat.

Oviposition was not affected by intercropping, but significantly fewer larvae...... and wandering spiders, were not augmented by intercropping, but an inverse relationship in abundance was found between these two predator groups. It is concluded that maize intercropped with cowpea has only limited potential as a method of controlling the key pests in maize....

Local ordinances as an instrument of social exclusion: the regulation affecting the homeless is administrative law of the enemy

Eduardo Melero Alonso

2017-03-01

Full Text Available This paper discusses local ordinances, especially the so-called coexistence ordinances, to the extent they affect the daily activities of the homeless. There are three areas of regulation: the prohibition of begging; a ban on sleeping, washing and perform physiological needs in public spaces; and the prohibition of sorting through garbage. This regulation is subjected to a critical analysis, focusing on the fact that has an impact on the fundamental rights of the homeless. The basic parameters of control are the reserve of law and, above all, the principle of proportionality. The conclusion reached is that, in many cases, this regulation is not only illegal, it can also be included within the category Administrative Law of the enemy.

Spodoptera exigua, which feeds on various crops worldwide, has natural enemies that are susceptible to the insecticides used against S. exigua. We investigate the toxicity and residue risk of 9 insecticides on the development of H. axyridis, C. sinica, S. manilae and T. remus. S. manilae and T. remus adults were sensitive to all 9 insecticides (LC50 less than 2.75 mg a.i. liter−1), while H. axyridis and C. sinica adults were less sensitive (LC50 between 6 × 10−5 mg a.i. liter−1 and 78.95 mg a.i. liter−1). Emamectin benzoate, spinosad, indoxacarb, alpha-cypermethrin, chlorfenapyr and chlorantraniliprole showed no toxicity on H. axyridis, C. sinica, S. manilae and T. remus pupae with the recommended field concentrations. The risk analysis indicated that chlorantraniliprole is harmless to larvae of four natural enemies and adult of H. axyridis, C. sinica and S. manilae. Emamectin benzoate and spinosad had higher safety to the development of H. axyridis, C. sinica, S. manilae and T. remus with the risk duration less than 4d. Indoxacarb, tebufenozide, chlorfenapyr, methomyl, alpha-cypermethrin and chlorpyrifos showed dangerously toxic and long risk duration on S. manilae and T. remus adults. PMID:27958333

Optimal control of soybean aphid in the presence of natural enemies and the implied value of their ecosystem services.

Science.gov (United States)

Zhang, Wei; Swinton, Scott M

2012-04-15

By suppressing pest populations, natural enemies provide an important ecosystem service that maintains the stability of agricultural ecosystems systems and potentially mitigates producers' pest control costs. Integrating natural control services into decisions about pesticide-based control has the potential to significantly improve the economic efficiency of pesticide use, with socially desirable outcomes. Two gaps have hindered the incorporation of natural enemies into pest management decision rules: (1) insufficient knowledge of pest and predator population dynamics and (2) lack of a decision framework for the economic tradeoffs among pest control options. Using a new intra-seasonal, dynamic bioeconomic optimization model, this study assesses how predation by natural enemies contributes to profit-maximizing pest management strategies. The model is applied to the management of the invasive soybean aphid, the most significant serious insect threat to soybean production in North America. The resulting lower bound estimate of the value of natural pest control ecosystem services was estimated at $84 million for the states of Illinois, Indiana, Iowa, Michigan and Minnesota in 2005.

2011-09-01

A Beauveria bassiana strain Bb21 was isolated from naturally infected green peach aphid Myzus persicae (Hemiptera: Aphididae). The effects of the strain on M. persicae and its two predaceous natural enemies Chrysoperla carnea (Neuroptera: Chrysopidae) and Harmonia axyridis (Coleoptera: Coccinellidae) were investigated under laboratory conditions. Bb21 had strong pathogenicity to M. persicae, with the LD50 of 97 conidia x mm(-2) (45-191, 95% confidence interval), but was less pathogenic to the second instar nymph of C. carnea, with the LD50 of 1089 conidia x mm(-2). The LD50 for C. carnea was 10.2 times higher than that for M. persicae. The pathogenicity of Bb21 to H. axyridis was very weak, with a low infection rate of 13% even at a high concentration 5 x 10(8) conidia x mL(-1). The Bb21 at low conidia concentration had less effect on the developmental period and fecundity of the two predaceous natural enemies. However, when applied at the high concentration 5 x 10(8) spores x mL(-1), Bb21 shortened the larval stage of H. axyridis averagely by 1.4 d and decreased the adult emergence rate and fecundity by 33% and 14%, respectively, and shortened the larval stage of C. carnea averagely by 0.7 d and decreased the adult emergence rate and fecundity by 24% and 11%, respectively. Since the LD50 for green peach aphid was much lower than that for the two predaceous natural enemies, and had very low effect on the adult emergence rate and fecundity of the two predators at the concentration recommended for field spray, Bb21 could be applied as a biocontrol agent of M. persicae in the integrated management of pernicious organisms.

Relative toxicity and residual activity of insecticides used in blueberry pest management: mortality of natural enemies.

2014-02-01

A series of bioassays were conducted to determine the relative toxicities and residual activities of insecticides labeled for use in blueberry (Vaccinium corymbosum L.) on natural enemies, to identify products with low toxicity or short duration effects on biological control agents. In total, 14 insecticides were evaluated using treated petri dishes and four commercially available natural enemies (Aphidius colemani Viereck, Orius insidiosus [Say], Chrysoperla rufilabris [Burmeister], and Hippodamia convergens [Guérin-Menéville]). Dishes were aged under greenhouse conditions for 0, 3, 7, or 14 d before introducing insects to test residual activity. Acute effects (combined mortality and knockdown) varied by insecticide, residue age, and natural enemy species. Broad-spectrum insecticides caused high mortality to all biocontrol agents, whereas products approved for use in organic agriculture had little effect. The reduced-risk insecticide acetamiprid consistently caused significant acute effects, even after aging for 14 d. Methoxyfenozide, novaluron, and chlorantraniliprole, which also are classified as reduced-risk insecticides, had low toxicity, and along with the organic products could be compatible with biological control. This study provides information to guide blueberry growers in their selection of insecticides. Further research will be needed to determine whether adoption of a pest management program based on the use of more selective insecticides will result in higher levels of biological control in blueberry.

COMPARATIVE EFFICACY OF SYNTHETIC AND BOTANICAL INSECTICIDES AGAINST SUCKING INSECT PEST AND THEIR NATURAL ENEMIES ON COTTON CROP

M. A. Baker

2016-08-01

Full Text Available The Synthetic and botanical insecticides are relatively safer for environment and beneficial insects. The study was conducted in Rahim Yar Khan during the cotton cropping season 2014 to evaluate the comparative efficacy of two Synthetic insecticides i.e. Nitenpyram (Jasper 10% SL and Pyriproxyfen (Bruce 10.8% EC and two botanical extracts of Calotropic procera and Azadirachta indica, against sucking insect pest complex of cotton and their natural enemies. Upon reaching economic thresholds, the recommended field doses of all the insecticides were applied on cotton cultivar MNH-886. Data against sucking pests and their natural enemies was recorded 24 hours prior to insecticidal application and then 24, 48, 72 and 96 hours after insecticidal application. Results revealed that Nitenpyram was much toxic against sucking pests followed by Pyriproxyfen as compared to two botanical extracts. On the other hand, the synthetic insecticides did not prove safer for natural enemies as compared to botanical extracts. It was concluded that as an Integrated Pest Management (IPM strategy, botanical extracts can be used at low infestation levels so that ecosystem service of biological control may be sustained.

Understanding how arthropod pests and their natural enemies interact in complex agroecosystems is essential for pest management programmes. Theory predicts that prey sharing a predator, such as a biological control agent, can indirectly reduce each other's density at equilibrium (apparent

The tomato leafminer, Tuta absoluta (Meyrick), had established in Israel by 2010, attacking both open-field tomatoes and greenhouse crops.We searched for its natural enemies in open-field tomatoes, and tried to determine their potential for controlling this pest. We surveyed the local natural enemies in open tomato fields and measured their impact on pest populations in an unsprayed field. We assessed the suppressive ability of the dominant hemipteran predator, Nesidiocoris tenuis Reuter, against T. absoluta under controlled laboratory conditions and evaluated the impact of its augmentation on T. absoluta control in open-field tomatoes. We found five natural enemy species:the predator, N. tenuis, two braconids, and two eulophids. Predation accounted for 64.5±9.2% (mean ± SE) of T. absoluta larval mortality, whereas parasitism accounted for 20.96±7.5%. Together, they eliminated the pest population at tomato harvest time. Under controlled conditions, predation by N. tenuis rose from 58 to 72% with increased density of T. absoluta, suggesting positive density dependence. The reduction of T. absoluta (83%) by N. tenuis was higher than that of Bemisia tabaci (32%), suggesting a preference of N. tenuis for T. absoluta. Augmentation of N.tenuis was as effective as conventional treatment insecticide treatment, and plant damage was low and did not seem to affect yield. Results indicate that reduced pesticide use enables indigenous natural enemies, particularly N.tenuis, to successfully control T. absoluta and prevent crop damage in open-field tomatoes.

Full Text Available In this article we analyze the process of stereotype thinking and its verbal expression. We focus our attention on the symbolic vision of our society in the mind of Europeans: Russia is evil, a country where law and democracy have deteriorated. Our aim is to examine the process of mind manipulation and imprinting of the enemy image on the mind of the society by means of communication and show the difficulty of destruction of stereotypes which prevents people of the 21st century from the objective perception of reality. We conducted our study on dictionary entries, articles, B.Obama’s speech in particular, and the extract from David Mitchell’s book “Black Swan Green”. The research is based on the data worked out by a number of sciences: Cultural Linguistics, Psychology, Psycholinguistics, Cross-Cultural Communication. We used the methods of functional and pragmatic analysis of the text. A stereotype is defined as an element of the cultural code which can be decoded by means of language; itt affects the way of thinking, behavior and lexis. Thus, the proposed thesis of a stereotype is supposed to be changing but too slowly. It is concluded that the sterotype “Russia is the enemy” possesses its formal linguistic, mental, and behavioural parametres.

A 3-yr field study was conducted at commercial grape (Vitis spp.) farms to evaluate insect management programs for control of the grape berry moth, Paralobesia viteana Clemens (Lepidoptera: Tortricidae) and conservation of natural enemies. At each farm, one vineyard received only reduced-risk insecticides for control of second and third generation P. viteana, whereas the comparison vineyard received conventional insecticides. Both vineyards received a conventional insecticide application for control of first generation P. viteana and other insect pests. Monitoring with pheromone traps showed no differences between programs in the total number of adult male moths trapped in vineyards, and oviposition by P. viteana was similar between the two programs in all 3 yr. During weekly samples of crop infestation, both programs had a similar percentage of clusters infested by P. viteana larvae. Berries infested by P. viteana were collected from vineyard borders during the second and third P. viteana generations and held under controlled conditions. In eight of the nine berry samples, survival of larvae was significantly lower in berries collected from vineyards managed under the reduced-risk insecticide program compared with the conventional program. Parasitism of P. citeana larvae in these samples was not consistently different between the two insecticide programs over 3 yr, and similar captures of natural enemies were found on yellow sticky traps in the two programs throughout the study. Our results indicate that integrated pest management programs incorporating reduced-risk insecticides for control of P. viteana can obtain similar or greater control of P. viteana compared with programs based solely on conventional insecticides, but they may not lead to measurable long-term increases in parasitism of P. viteana.

Plant viruses transmitted by arthropods, as an important biotic factor, may not only directly affect the yield and quality of host plants, and development, physiological characteristics and ecological performances of their vector arthropods, but also directly or indirectly affect the non-vector herbivorous arthropods and their natural enemies in the same ecosystem, thereby causing influences to the whole agro-ecosystem. This paper reviewed the progress on the effects of plant viruses on herbivorous arthropods, including vector and non-vector, and their natural enemies, and on their ecological mechanisms to provide a reference for optimizing the management of vector and non-vector arthropod populations and sustainable control of plant viruses in agro-ecosystem.

Carl Schmitt's attitude towards total war and total enemy on the eve of the outbreak of WWII

Molnar Aleksandar

2010-01-01

Full Text Available Carl Schmitt is usually perceived as the theorist of total state, total war and total hostility. In the article, the author however tries to show that from 1937 to 1944, Schmitt was arguing that total war and total hostility were dangerous for Germany (as well as for the rest of Europe and warned against perpetuation of all efforts to totalize enemy that started in 1914. In his theoretical endeavors in this period there was place for the total state only - and especially for the total state strong enough to resist temptation of declaring total war on total enemy. The total state he recommended Hitler and his Nazi comrades was German Reich, as a part of Europe ordered and divided in the huge spaces (Grossraumordnung. Positioned in the centre of Europe, between the rest of the powers (France, Italy, USSR as well as the Scandinavian states, Germany should be careful enough to wage war only against its Eastern enemies (Poland and maybe USSR and only in order to achieve 'just' borders. Occupying in this way its huge space Germany should devote itself to the task of exploitation of various peoples such as Poles, Chechs and Slovaks, which were perceived as incapable of having their states and doomed to serve the master race - the Germans.

The Accreditation Council for Graduate Medical Education (ACGME) requires orthopaedic residency programs to promote scholarship and research, which manifest differently among programs. We assess the impact of protected research time during orthopaedic residency on the number of resident publications. Rotation schedules and resident names were collected from 125 ACGME-accredited U.S. orthopaedic residency programs. Protected research time was classified as 1 of 3 types: (1) block time, (2) longitudinal time, or (3) no dedicated time. In April 2016, we searched residents in postgraduate year (PGY)-3 to PGY-5 on pubmed.gov to generate all orthopaedic publications with a PubMed identifier published during residency. Each publication's 2015 Thomson Reuters Journal Citation Reports 5-Year Journal Impact Factor and resident first authorship were noted. The number of PubMed identifiers for each program was summed and was divided by the number of residents in PGY-3 to PGY-5, giving a mean number of publications per resident. The relationship between output and program research time was compared using t tests and analysis of variance (ANOVA). A total of 1,690 residents were included, with an overall mean number (and standard deviation) of 1.2 ± 2.4 publications per resident. Eighty-seven programs reported block time, 14 programs reported longitudinal time, and 24 programs reported no time. There was a significant difference (p = 0.02) in the mean number of publications per resident when compared between programs with protected time (1.1 ± 1.2 publications) and programs with no protected time (0.6 ± 0.5 publication). One-way ANOVA demonstrated a significant mean difference across the 3 groups (p publications than block time at 1.0 ± 1.0 publication or no time at 0.6 ± 0.5 publication, a difference that persisted when adjusted to include only impact factors of >0 and exclude case reports (p = 0.0015). Both the presence of and the type of dedicated research time correlate

Diversity and Activity of Insect Natural Enemies of the Bag worm (Lepidoptera: Psychidae) within an Oil Palm Plantation in Perak, Malaysia

2016-01-01

Bag worms (Lepidoptera: Psychidae) are one of the important leaf-eating pests of oil palm in Malaysia and Indonesia. Crop losses, due to the extensive defoliation by a serious bag worm attack are inevitable. The establishment and propagation of the bag worm's parasitoids, depend very much on species of flowering plants as sources of nectar. Cassia cobanensis, was proven suitable due to its attractiveness to most bag worm parasitoids. A study to assess the diversity of bag worm's natural enemies (hymenopterous parasitoids and reduuvid predatory bugs) on the C. cobanensis plant and within the undergrowth of the oil palm planting block was evaluated by sweep net and sticky trap sampling. Environmental parameters such as light intensity, temperature and relative humidity were also recorded during the sampling to determine their possible range of influence towards the activity of the insect natural enemies. The Shannon-Wiener diversity index of insect natural enemies occurring on the C. cobanensis plant was 2.32. Among the dominant parasitoids observed on C. cobanensis plants are chalcids (Brachymeria lugubris and Brachymeria carinata) and braconids (Dolichogenidea metesae and Apanteles aluella), besides the reduuvid predator, Cosmolestes picticeps. In contrast, within the oil palm planting block, the undergrowth within the non-harvesting path only recorded a much lower diversity index of 1.09 and 1.12 each, in a block with C. cobanensis at the roadside and without, respectively. However, C. picticeps was shown to be much more dominant within both oil palm planting blocks, up to two- to three-fold, with much lesser numbers of hymenopterous parasitoids (less than five individuals). This indicates the important contribution of C. cobanensis plant towards enriching the diversity of the parasitoids, which are normally not found within the oil palm block, due to much less intense sunlight. In terms of insect activity, they are significantly more active in the

Invasive plants and enemy release: evolution of trait means and trait correlations in Ulex europaeus.

Science.gov (United States)

Hornoy, Benjamin; Tarayre, Michèle; Hervé, Maxime; Gigord, Luc; Atlan, Anne

2011-01-01

Several hypotheses that attempt to explain invasive processes are based on the fact that plants have been introduced without their natural enemies. Among them, the EICA (Evolution of Increased Competitive Ability) hypothesis is the most influential. It states that, due to enemy release, exotic plants evolve a shift in resource allocation from defence to reproduction or growth. In the native range of the invasive species Ulex europaeus, traits involved in reproduction and growth have been shown to be highly variable and genetically correlated. Thus, in order to explore the joint evolution of life history traits and susceptibility to seed predation in this species, we investigated changes in both trait means and trait correlations. To do so, we compared plants from native and invaded regions grown in a common garden. According to the expectations of the EICA hypothesis, we observed an increase in seedling height. However, there was little change in other trait means. By contrast, correlations exhibited a clear pattern: the correlations between life history traits and infestation rate by seed predators were always weaker in the invaded range than in the native range. In U. europaeus, the role of enemy release in shaping life history traits thus appeared to imply trait correlations rather than trait means. In the invaded regions studied, the correlations involving infestation rates and key life history traits such as flowering phenology, growth and pod density were reduced, enabling more independent evolution of these key traits and potentially facilitating local adaptation to a wide range of environments. These results led us to hypothesise that a relaxation of genetic correlations may be implied in the expansion of invasive species.

The analysis plan and article in this issue of the Journal by Evenson et al. (Am J Epidemiol 2016;184(9):621-632) is well-conceived, thoughtfully conducted, and tightly written. The authors utilized the National Health and Nutrition Examination Survey data set to examine the association between accelerometer-measured physical activity level and mortality and found that meeting the 2013 federal Physical Activity Guidelines resulted in a 35% reduction in risk of mortality. The timing of these findings could not be better, given the ubiquitous nature of personal accelerometer devices. The masses are already equipped to routinely quantify their activity, and now we have the opportunity and responsibility to provide evidenced-based, tailored physical activity goals. We have evidenced-based physical activity guidelines, mass distribution of devices to track activity, and now scientific support indicating that meeting the physical activity goal, as assessed by these devices, has substantial health benefits. All of the pieces are in place to make physical inactivity a national priority, and we now have the opportunity to positively affect the health of millions of Americans. © The Author 2016.

Avoid, attack or do both? Behavioral and physiological adaptations in natural enemies faced with novel hosts

Directory of Open Access Journals (Sweden)

Brown Sam P

2005-11-01

Full Text Available Abstract Background Confronted with well-defended, novel hosts, should an enemy invest in avoidance of these hosts (behavioral adaptation, neutralization of the defensive innovation (physiological adaptation or both? Although simultaneous investment in both adaptations may first appear to be redundant, several empirical studies have suggested a reinforcement of physiological resistance to host defenses with additional avoidance behaviors. To explain this paradox, we develop a mathematical model describing the joint evolution of behavioral and physiological adaptations on the part of natural enemies to their host defenses. Our specific goals are (i to derive the conditions that may favor the simultaneous investment in avoidance and physiological resistance and (ii to study the factors that govern the relative investment in each adaptation mode. Results Our results show that (i a simultaneous investment may be optimal if the fitness costs of the adaptive traits are accelerating and the probability of encountering defended hosts is low. When (i holds, we find that (ii the more that defended hosts are rare and/or spatially aggregated, the more behavioral adaptation is favored. Conclusion Despite their interference, physiological resistance to host defensive innovations and avoidance of these same defenses are two strategies in which it may be optimal for an enemy to invest in simultaneously. The relative allocation to each strategy greatly depends on host spatial structure. We discuss the implications of our findings for the management of invasive plant species and the management of pest resistance to new crop protectants or varieties.

Many species are currently moving to higher latitudes and altitudes. However, little is known about the factors that influence the future performance of range-expanding species in their new habitats. Here we show that range-expanding plant species from a riverine area were better defended against shoot and root enemies than were related native plant species growing in the same area. We grew fifteen plant species with and without non-coevolved polyphagous locusts and cosmopolitan, polyphagous aphids. Contrary to our expectations, the locusts performed more poorly on the range-expanding plant species than on the congeneric native plant species, whereas the aphids showed no difference. The shoot herbivores reduced the biomass of the native plants more than they did that of the congeneric range expanders. Also, the range-expanding plants developed fewer pathogenic effects in their root-zone soil than did the related native species. Current predictions forecast biodiversity loss due to limitations in the ability of species to adjust to climate warming conditions in their range. Our results strongly suggest that the plants that shift ranges towards higher latitudes and altitudes may include potential invaders, as the successful range expanders may experience less control by above-ground or below-ground enemies than the natives.

Weeds and their influence on pest and natural enemy populations were studied on a commercial ornamental farm during 2009 in the Atlantic Zone of Costa Rica. A baseline survey of the entire production plot was conducted in February, along a 5 by 5 m grid to characterize and map initial weed communities of plants, cicadellids, katydids, and armored scales. In total, 50 plant species from 21 families were found. Seven weed treatments were established to determine how weed manipulations would affect communities of our targeted pests and natural enemies. These treatments were selected based on reported effects of specific weed cover on herbivorous insects and natural enemies, or by their use by growers as a cover crop. Treatments ranged from weed-free to being completely covered with endemic species of weeds. Although some weed treatments changed pest abundances, responses differed among arthropod pests, with the strongest effects observed for Caldwelliola and Empoasca leafhoppers. Removal of all weeds increased the abundance of Empoasca, whereas leaving mostly cyperacaeous weeds increased the abundance of Caldwelliola. Weed manipulations had no effect on the abundance of katydid and scale populations. No weed treatment reduced the abundance of all three of the target pests. Differential responses of the two leafhopper species to the same weed treatments support hypotheses, suggesting that noncrop plants can alter the abundance of pests through their effects on arthropod host finding and acceptance, as well as their impacts on natural enemies.

Dissemination of Aleurocanthus woglumi in citrus plants, its natural enemies and new host plants in the state of Rio de Janeiro, Brazil

Directory of Open Access Journals (Sweden)

Rodrigo Garcia Alvim

Full Text Available ABSTRACT: Aleurocanthus woglumi is an exotic pest, widely disseminated in Brazil, with a high preference for citrus plants, but with a polyphagous feeding habit. The contribution of the state of Rio de Janeiro in the Brazilian production of citrus fruits is small; however, there are still public policies that encourage citrus production in the state. In 2010, the appearance of this pest in Rio de Janeiro was confirmed in the municipality of Cachoeiras de Macacu. The objectives of this research were to evaluate the dissemination of A. woglumi in this state, conduct a survey of new species of host plants, identify and evaluate the population of natural enemies present at two orchards that grow 'Tahiti' limes ( Citrus latifolia infested by the pest in Cachoeiras de Macacu, RJ, Brazil. In 19 municipalities, leaves of citrus and other species of plants presenting aleyrodid nymphs were collected, and yellow sticky traps were installed to capture adults for subsequent identification. At the 'Tahiti' lime orchards, the leaf collections were done to confirm the species of Aleyrodidae , and regarding A. woglumi , the natural enemies associated with this pest were collected directly from the infested plants. The results showed that A. woglumi is wide-spread in 12 municipalities. Three new host plants for A. woglumi were identified: Artocarpus heterophyllus ( Moraceae , Pouteria caimito ( Sapotaceae and Struthanthus flexicaulis ( Loranthaceae . In Cachoeiras de Macacu, a new species of parasitoid of A. woglumi nymphs was named: Encarsia pergandiella (Hymenoptera: Aphelinidae , while the insects in the Coccinellidae (Coleoptera family have stood out as predators of this pest.

2014-08-01

Semiochemicals released by plants or insects play an important role in the communication among plants, phytophagous insects and their natural enemies. They thus form a chemical information network which regulates intra- and inter-specific behaviors and sustains the composition and structure of plant and insect communities. The application of insect-resistant genetically modified (IRGM) crops may affect the chemical communication within and among the tritrophic levels, and thus cause disturbances to the biotic community structure and the stability of the farmland ecosystem. This has raised concerns about the environmental safety of IRGM crops and triggered research worldwide. In the current article we provided a brief summary of the chemical communication among plants, herbivores and natural enemies; analyzed the potential of IRGM crops to affect the chemical communication between plants and arthropods and the related mechanisms; and discussed the current research progress and the future prospects in this field. We hope that this will promote the research in this field by Chinese scientists and increase our understanding of the potential effects of growing of IRGM crops on the arthropod community structure.

Responses of Crop Pests and Natural Enemies to Wildflower Borders Depends on Functional Group.

McCabe, Ellie; Loeb, Gregory; Grab, Heather

2017-07-25

Increased homogeneity of agricultural landscapes in the last century has led to a loss of biodiversity and ecosystem services. However, management practices such as wildflower borders offer supplementary resources to many beneficial arthropods. There is evidence that these borders can increase beneficial arthropod abundance, including natural enemies of many pests. However, this increase in local habitat diversity can also have effects on pest populations, and these effects are not well-studied. In this study, we investigated how wildflower borders affect both natural enemies and pests within an adjacent strawberry crop. Significantly more predators were captured in strawberry plantings with wildflower borders versus plantings without wildflowers, but this effect depended on sampling method. Overall, herbivore populations were lower in plots with a wildflower border; however, responses to wildflower borders varied across specific pest groups. Densities of Lygus lineolaris (Tarnished Plant Bug), a generalist pest, increased significantly in plots that had a border, while Stelidota geminata (Strawberry Sap Beetle) decreased in strawberry fields with a wildflower border. These results suggest that wildflower borders may support the control of some pest insects; however, if the pest is a generalist and can utilize the resources of the wildflower patch, their populations may increase within the crop.

Floral resource utilization by solitary bees (Hymenoptera: Apoidea) and exploitation of their stored foods by natural enemies.

Science.gov (United States)

Wcislo, W T; Cane, J H

1996-01-01

Bees are phytophagous insects that exhibit recurrent ecological specializations related to factors generally different from those discussed for other phytophagous insects. Pollen specialists have undergone extensive radiations, and specialization is not always a derived state. Floral host associations are conserved in some bee lineages. In others, various species specialize on different host plants that are phenotypically similar in presenting predictably abundant floral resources. The nesting of solitary bees in localized areas influences the intensity of interactions with enemies and competitors. Abiotic factors do not always explain the intraspecific variation in the spatial distribution of solitary bees. Foods stored by bees attract many natural enemies, which may shape diverse facets of nesting and foraging behavior. Parasitism has evolved repeatedly in some, but not all, bee lineages. Available evidence suggests that cleptoparasitic lineages are most speciose in temperate zones. Female parasites frequently have a suite of characters that can be described as a masculinized feminine form. The evolution of resource specialization (including parasitism) in bees presents excellent opportunities to investigate phenotypic mechanisms responsible for evolutionary change.

Changes in defense of an alien plant Ambrosia artemisiifolia before and after the invasion of a native specialist enemy Ophraella communa.

Directory of Open Access Journals (Sweden)

Yuya Fukano

Full Text Available The evolution of increased competitive ability hypothesis (EICA predicts that when alien plants are free from their natural enemies they evolve lower allocation to defense in order to achieve a higher growth rate. If this hypothesis is true, the converse implication would be that the defense against herbivory could be restored if a natural enemy also becomes present in the introduced range. We tested this scenario in the case of Ambrosia artemisiifolia (common ragweed - a species that invaded Japan from North America. We collected seeds from five North American populations, three populations in enemy free areas of Japan and four populations in Japan where the specialist herbivore Ophraella communa naturalized recently. Using plants grown in a common garden in Japan, we compared performance of O. communa with a bioassay experiment. Consistent with the EICA hypothesis, invasive Japanese populations of A. artemisiifolia exhibited a weakened defense against the specialist herbivores and higher growth rate than native populations. Conversely, in locations where the herbivore O. communa appeared during the past decade, populations of A. artemisiifolia exhibited stronger defensive capabilities. These results strengthen the case for EICA and suggest that defense levels of alien populations can be recuperated rapidly after the native specialist becomes present in the introduced range. Our study implies that the plant defense is evolutionary labile depending on plant-herbivore interactions.

A key challenge for evolutionary biologists is to determine conditions under which individuals benefit from a contribution to public goods [1, 2]. For humans, it has been observed that punishment of free riders may promote contributions [3, 4], but the conditions that lead to stable cooperation based on punishment remain hotly debated [5-8]. Here we present empirical evidence that public goods may emerge as a by-product of self-serving punishment in interactions between coral reef fishes and parasitic saber-tooth blennies that stealthily attack their fish victims from behind to take a bite [9]. We first show that chasing the blenny functions as punishment [10], because it decreases the probability of future attacks. We then provide evidence that in female scalefin anthias, a shoaling species, punishment creates a public good because it increases the probability that the parasite switches to another species for the next attack. A final experiment suggests that punishment is nevertheless self-serving because blennies appear to be able to discriminate between look-alike punishers and nonpunishers. Thus, individuals that do contribute to the public good may risk being identified by the parasite as easy targets for future attacks. Copyright © 2010 Elsevier Ltd. All rights reserved.

Since the inception of resident work-hour regulations, there has been considerable concern regarding the influence of decreased work hours on graduate medical education. In particular, it is unclear whether implementation of work-hour restrictions has influenced resident academic performance as defined by quantity of peer-reviewed publications while participating in graduate medical education. We determined the impact of work-hour changes on resident involvement in the number of published clinical studies, laboratory research, case reports, and review articles. We conducted a PubMed literature search of 139 consecutive orthopaedic surgery residents (789 total resident-years) at one institution from academic years 1995-1996 to 2008-2009. This represented a continuous timeline before and after implementation of work-hour restrictions. The number of resident publications before and after implementation of work-hour changes was compared. There was a greater probability of peer review authorship in any given resident-year after work-hour changes than before. Average publications per resident-year increased for total articles, clinical articles, case reports, and reviews. There was an increased rate of publications in which the resident was the first author. Since implementation of work-hour changes, total resident publications and publications per resident-year have increased.

Generalist natural enemies play an important role in controlling soybean aphid, Aphis glycines (Hemiptera: Aphididae), in North America. Several sampling methods are used to monitor natural enemy populations in soybean, but there has been little work investigating their relative bias, precision, and efficiency. We compare five sampling methods: quadrats, whole-plant counts, sweep-netting, walking transects, and yellow sticky cards to determine the most practical methods for sampling the three most prominent species, which included Harmonia axyridis (Pallas), Coccinella septempunctata L. (Coleoptera: Coccinellidae), and Orius insidiosus (Say) (Hemiptera: Anthocoridae). We show an important time by sampling method interaction indicated by diverging community similarities within and between sampling methods as the growing season progressed. Similarly, correlations between sampling methods for the three most abundant species over multiple time periods indicated differences in relative bias between sampling methods and suggests that bias is not consistent throughout the growing season, particularly for sticky cards and whole-plant samples. Furthermore, we show that sticky cards produce strongly biased capture rates relative to the other four sampling methods. Precision and efficiency differed between sampling methods and sticky cards produced the most precise (but highly biased) results for adult natural enemies, while walking transects and whole-plant counts were the most efficient methods for detecting coccinellids and O. insidiosus, respectively. Based on bias, precision, and efficiency considerations, the most practical sampling methods for monitoring in soybean include walking transects for coccinellid detection and whole-plant counts for detection of small predators like O. insidiosus. Sweep-netting and quadrat samples are also useful for some applications, when efficiency is not paramount. © The Authors 2015. Published by Oxford University Press on behalf of

Sleeping with the Political Enemy: Woman’s Place in Discourses of Race and Class Struggle in 20th Century Central Europe

2011-01-01

Full Text Available In this paper, I shall argue that the convergence of ideologies operating through the creation of enemies like racism and Bolshevism with discourses regulating gender relations in the Central Europe of the twentieth century had the grave consequence of questioning women’s position in the political community. In short, I shall argue that in the context of racist and Bolshevik discourses, the very fact of being female was in itself a political threat to women. To demonstrate my point, I shall discuss two recent publications. First, I shall analyze the context of the convergence of racist and misogynist discourses in turn-of-the-century Vienna through discussing András Gerő’s book, Neither Woman Nor Jew. Second, I shall explore how the discourse of class struggle affected the political status of Hungarian women in the Stalinist era through discussing Eszter Zsófia Tóth’s book, Kádár’s Daughters.

The indirect effects of predators on nonadjacent trophic levels, mediated through traits of intervening species, are collectively known as trait-mediated trophic cascades. Although birds are important predators in terrestrial ecosystems, clear examples of trait-mediated indirect effects involving bird predators have almost never been documented. Such indirect effects are important for structuring ecological communities and are likely to be negatively impacted by habitat fragmentation, climate change, and other factors that reduce abundance of top predators. We demonstrate that hummingbirds in Arizona realize increased breeding success when nesting in association with hawks. An enemy-free nesting space is created when jays, an important source of mortality for hummingbird nests, alter their foraging behavior in the presence of their hawk predators.

United States military doctrine permits the use of fresh whole blood (FWB), donated by U.S. military personnel on site, for casualties with life-threatening injuries at combat support hospitals. U.S. Military Medical Department policy dictates that all patients treated at military facilities during combat (coalition military personnel, foreign nationals, and enemy combatants) are to be treated equally. The objectives of this study were to describe admission vital signs and laboratory values and injury location for patients transfused with FWB, and to determine if FWB was employed equally among all patient personnel categories at a combat support hospital. This retrospective cohort study evaluated admission vital signs and laboratory values, injury location, and personnel category for all patients receiving FWB at a U.S. Army combat support hospital in Baghdad, Iraq, between January and December 2004. Eighty-seven patients received 545 units of FWB. Upon admission, the average (+/-S.D.) heart rate was 144 bpm (+/-25); systolic blood pressure, 106 mmHg (+/-33); base deficit, 9 (+/-6.5); hemoglobin, 9.0 g/dl (+/-2.6); platelet concentration, 81.9 x 10(3)/mm(3) (+/-81); international normalized ratio (INR), 2.0 (+/-1.1); and temperature 95.7 degrees F (+/-2.6). The percentages of intensive care patients who received FWB by personnel category were as follows: coalition soldiers, 51/592 (8.6%); foreign nationals, 25/347 (7.2%); and enemy combatants, 11/128 (8.5% (p = 0.38). The amount of FWB transfused by personnel category was as follows: coalition soldier, 4 units (1-35); foreign national, 4 units (1-36); and enemy combatant, 4 units (1-11) (p = 0.9). Fresh whole blood was used for anemic, acidemic, hypothermic, coagulopathic patients with life-threatening traumatic injuries in hemorrhagic shock, and it was transfused in equal percentages and amounts for coalition soldiers, foreign nationals, and enemy combatants.

Hazinedar, Ä.°lker

2015-05-01

Since air vehicles took place in the theater of operations, they have become the indispensable elements and the strongest attack power of armed forces. In the following period, with technological development, supersonic aircrafts took place in the operation area and this increased effectiveness of air vehicles much more. Air forces have used these aircrafts during important missions like strategic attack and air defense operations. On the other hand, decision makers understood that it was not feasible to intercept fighter aircrafts by executing combat air patrol flight missions. Since there is not enough reaction time to intercept the high speed aircrafts, ground stationed Surface to Air Missiles (SAM) system requirement has emerged. Therefore, SAM systems took place in the operation scene as well. Due to the fact that SAM systems emerged against the attack power, the attack aircrafts are to keep away from the fire of the ground stationed SAM systems. Hence, the requirement of Suppression Enemy Air Defense (SEAD) arose. SEAD elements take under suppression the radar of the SAM systems. In this way, attack aircrafts are able to attack without the risk of SAM systems. The purpose of this study is to find new methods or concepts in order to protect friendly attack aircrafts against ground based surface to air missiles' fires. Modernization of SAM systems and new generation SAM system producing activities have proceeded with positive acceleration. So, current SEAD elements and concepts are not able to cover the requirements due to the increased SAM system ranges. According to the concepts, SEAD weapons` ranges must be longer than the SAM weapons' ranges to protect friendly aircrafts. In this study, new concept was offered to overcome the deficiencies of current SEAD concept. The elements of new concepts were put forward. Classic SEAD concept and new generation concepts were assessed by using SWOT analysis technique. As a result, this study has revealed that, air forces

The world's uneasiness and mistrust regarding anything nuclear has heightened in recent years due to events such as Chernobyl and Three Mile Island. Opinion polls and attitude surveys document the public's growing concern about issues such as the depletion of the ozone layer, the resulting greenhouse effect and exposure of our planet to cosmic radiation. Ultimately, such research reveals an underlying fear regarding the unseen impacts of modern technology on the environment and on human health. These concerns have obvious implications for the radiation processing industry, whose technology is nuclear based and not easily understood by the public. We have already seen organized nuclear opponents mobilize public anxiety, fear and misunderstanding in order to oppose the installation of radiation processing facilities and applications such as food irradiation. These opponents will no doubt try to strengthen resistance to our technology in the future. Opponents will attempt to convince the public that the risks to public and personal health and safety outweigh the benefits of our technology. We in the industry must head off any tendency for the public to see us as the "enemy". Our challenge is to counter public uneasiness and misunderstanding by effectively communicating the human benefits of our technology. Clearly it is a challenge we cannot afford to ignore.

2013-05-01

Full Text Available The Second Vatican Council (1962–1965 is regarded as one of the most significant processes in the ecumenical church history of the 20th century. At that time, a younger generation of Roman Catholic theologians began to make their mark in the church and within the ecumenical theological scene. Their work provided an ecumenical bridge between the Reforming and the Roman Catholic ecclesiastical traditions, notwithstanding the subsequent negative response of the Roman church hierarchy. Despite important advances, recent pontificates significantly altered the theological landscape and undermined much of the enthusiasm and commitment to unity. Roman Catholic theological dissent provided common ground for theological reflection. Those regarded as the ‘enemy within’ have become respected colleagues in the search for truth in global ecclesiastical perspective. This article will use the distinction between the history and the narratives of Vatican II.

Collective defense of Aphis nerii and Uroleucon hypochoeridis (Homoptera, Aphididae against natural enemies.

Directory of Open Access Journals (Sweden)

Manfred Hartbauer

2010-04-01

Full Text Available The prevalent way aphids accomplish colony defense against natural enemies is a mutualistic relationship with ants or the occurrence of a specialised soldier caste typical for eusocial aphids, or even both. Despite a group-living life style of those aphid species lacking these defense lines, communal defense against natural predators has not yet been observed there. Individuals of Aphis nerii (Oleander aphid and Uroleucon hypochoeridis, an aphid species feeding on Hypochoeris radicata (hairy cat's ear, show a behavioral response to visual stimulation in the form of spinning or twitching, which is often accompanied by coordinated kicks executed with hind legs. Interestingly, this behaviour is highly synchronized among members of a colony and repetitive visual stimulation caused strong habituation. Observations of natural aphid colonies revealed that a collective twitching and kicking response (CTKR was frequently evoked during oviposition attempts of the parasitoid wasp Aphidius colemani and during attacks of aphidophagous larvae. CTKR effectively interrupted oviposition attempts of this parasitoid wasp and even repelled this parasitoid from colonies after evoking consecutive CTKRs. In contrast, solitary feeding A. nerii individuals were not able to successfully repel this parasitoid wasp. In addition, CTKR was also evoked through gentle substrate vibrations. Laser vibrometry of the substrate revealed twitching-associated vibrations that form a train of sharp acceleration peaks in the course of a CTKR. This suggests that visual signals in combination with twitching-related substrate vibrations may play an important role in synchronising defense among members of a colony. In both aphid species collective defense in encounters with different natural enemies was executed in a stereotypical way and was similar to CTKR evoked through visual stimulation. This cooperative defense behavior provides an example of a surprising sociality that can be found

Full Text Available The banana weevil, Cosmopolites sordidus Germar, is an important pest of highland banana and plantain in Africa, but it exists in low densities in presumed area of origin in Southeast Asia such as in Indonesia. This suggests a possible existence of effective co-evolved natural enemies in the origin area of Indonesia, especially West Sumatra. The objectives of this study were: (1 to evaluate banana weevil pest status at selected sites in West Sumatra, (2 to survey parasitoids and predators, and (3 to determine the control potential of the most important natural enemies. Surveys were undertaken in March 2002-August 2003 in five locations in West Sumatra, i.e., Bukittinggi, Sitiung, Pariaman, Pasaman, and Batusangkar. Five farms per site were selected randomly among all farms that contained banana stands of > 0.5 ha. Sampling for banana weevil adults and damage, and for predators was done throughout small banana stands and within a 20 m x 40 m (0.08 ha subplot on larger farms. Field-collected larvae were taken to the laboratory and reared on corm pieces (3 cm x 3 cm x 3 cm until pupation. Larvae were collected from pseudostem as well as corm residues. To estimate the abundance of non-social predators, i.e., those other than ants, 10 residues each on each farm were examined from plants that had been harvested 1-4 weeks, 5-8 weeks or 9 or more weeks before our visit to the site. Samples of the different morphospecies were saved in alcohol for later identification. The result showed that the banana weevil incidence was found to be low,  0.6-1.7 adults per trap. Plant damage indices were below 2.2%. We collected and reared 24,360 eggs and 3118 larvae, but no parasitism was detected. Phorids (Megaselia sp. and drosophilids were recovered from larval rearings, but most likely were scavengers. A complex of predators was detected, the most important of which was the histerid beetles,  Plaesius javanus Erichson. In laboratory tests, adults and larvae

Figuring Reconciliation: Dancing With the Enemy

2007-02-01

Full Text Available This essay is about fi guring “argument as dance” and one way of conceiving how to live or embody argument as such. Concretely, it displays “argument as war” alongside a road in Mississippi after a white man shoots down James Meredith as he asserts his legal right to vote. And it tells “how to” perceive the shooting as dance by turning fi rstly to the performance of dance fi gured in the beginnings of rhetoric and then secondly, setting forth demystifi ed methods and strategies of body-speech fi guring argument as dance, rather than as war, through performances of Nelson Mandela. More generally, it explores a new meaning or experience of rhetoric by explicitly conjoining two historical times, two geographies, two speakers, enemies and dancers, that are inextricably interconnected. Using a combination of description and analysis, the fi rst is a full display of three photographs picturing argument as war. The whole picture serves as a descriptive compass or guide for making our way analytically through argument as war and into dance language and behavior and their interconnections to argument. The second is a retrospective discussion of the background, dancing/argumentative practices, what is called “blinking on the behalf of the enemy,” of Nelson Mandela. Overall, the strategy of reticulating political times, chronology and political spaces, geography on the one hand, and argument as war and argument as dance on the other hand is to reconcile confl icting measures and to produce a performance practice (of rhetoric of which there is no canon.

In this study, we measured, under laboratory conditions, the direct and indirect effects of insecticides on mealybug destroyer, Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae), and parasitoid Leptomastix dactylopii Howard (Hymenoptera: Encyrtidae), natural enemies of citrus mealybug, Planococcus citri (Risso) (Homoptera: Pseudococcidae). The adult stages of both natural enemies were exposed to sprays of the insecticides buprofezin, pyriproxyfen, flonicamid, acetamiprid, dinotefuran, and clothianidin at label-recommended rates to assess direct mortality after 24, 48, and 72 h, respectively. The effects of the insecticides on L. dactylopii parasitization rate and percentage of parasitoid emergence also were monitored using the label and 4x the recommended label rate. Dinotefuran was extremely detrimental to the adult parasitoid at the label rate with 100% mortality after 24 h. Buprofezin, pyriproxyfen, and flonicamid were not harmful to L. dactylopii when applied at the label rate. At 4x the recommended label rate, dinotefuran, acetamiprid, and clothianidin were all harmful to the parasitoid with 100% mortality 72 h after application. Both buprofezin and flonicamid were not toxic to L. dactylopii with 100% adult survival after 72 h. Pyriproxyfen and flonicamid, at both the label and 4x the recommended label rate, did not negatively affect L. dactylopii parasitization rate or percentage of parasitoid emergence. Acetamiprid, dinotefuran, and clothianidin were toxic to C. montrouzieri adults with 100% mortality after 48 h, whereas buprofezin, pyriproxyfen, and flonicamid demonstrated minimal (10-20% mortality after 48 h) harmful effects to the predator. Based on the results from our study, the indirect effects of the insect growth regulator (IGR) buprofezin were not decisive; however, the IGR pyriproxyfen and the insecticide flonicamid were not directly or indirectly harmful to the predator C. montrouzieri and parastioid L. dactylopii, indicating that

Many ant and termite colonies are defended by soldiers with powerful mandibles or chemical weaponry. Recently, it was reported that several stingless bee species also have soldiers for colony defence. These soldiers are larger than foragers, but otherwise lack obvious morphological adaptations for defence. Thus, how these soldiers improve colony fitness is not well understood. Robbing is common in stingless bees and we hypothesized that increased body size improves the ability to recognize intruders based on chemosensory cues. We studied the Neotropical species Tetragonisca angustula and found that large soldiers were better than small soldiers at recognizing potential intruders. Larger soldiers also had more olfactory pore plates on their antennae, which is likely to increase their chemosensory sensitivity. Our results suggest that improved enemy recognition might select for increased guard size in stingless bees. © 2017 The Author(s).

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

Melons are an important export crop for Panama and are cultivated on more than 1000 ha of land. Long growing season, extending well into January, allows several generations and build up of heavy populations of an important insect pest, Aphis gossypii, the melon aphid. Growers find it difficult to cultivate melons without several applications of insecticides. Although the insecticide applications control the aphids, they may also have adverse effects on the natural enemies of the aphid, in particular the two predatory insects Cycloneda sanguinea and Chrysoperla carnea. The purpose of this research was to evaluate the impact of insecticide applications on these insects and on the yield of melons, and to estimate residues of the applied insecticides in soil. The insecticides were applied as four different type of treatments to melon crop. The treatments were (i) three periodic applications of endosulfan (Thiodan 35EC), each at 0.52 kg a.i./ha, (ii) three applications of fenitrothion (Sumithion 50WP), each at 0.35 kg a.i./ha, (iii) two applications of fenitrothion and one of endosulfan, and (iv) grower's treatment, which included applications of six different insecticides. The effect of the insecticide applications was evaluated by estimating numbers of each of the three type of insects before and within 72 hours after the applications and estimating yield of melons. All insecticide treatments reduced the populations of Aphis gossypii, but they also reduced the numbers of the benificial insects. Endosulfan was somewhat less toxic to C. carnea than the other insecticides were, since greater number of C. carnea were recorded from the plots treated with endosulfan than the other treated plots. The best yield of melons was recorded in the plots which were sprayed with fenitrothion, followed by the plots sprayed with endosulfan. and then those with grower's insecticides. Soon after the application of endosulfan the residue in the soil was 0.2 mg/kg, but it declined to less

Significance of the tropical fire ant Solenopsis geminata (hymenoptera: formicidae) as part of the natural enemy complex responsible for successful biological control of many tropical irrigated rice pests.

Way, M J; Heong, K L

2009-10-01

The tropical fire ant Solenopsis geminata (Fabricius) often nests very abundantly in the earthen banks (bunds) around irrigated rice fields in the tropics. Where some farmers habitually drain fields to the mud for about 3-4 days, the ants can quickly spread up to about 20 m into the fields where they collect food, including pest prey such as the eggs and young of the apple snail Pomacea caniculata (Lamarck) and insects such as lepidopterous larvae and hoppers, notably Nilaparvata lugens (Stäl) the brown planthopper (Bph) and green leafhoppers Nephotettix spp. Even in drained fields, the activity of S. geminata is restricted by rainfall in the wet season. The relatively few ant workers that forage characteristically into drained fields and on to the transplanted clumps of rice plants (hills) kill the normally few immigrant Bph adults but are initially slower acting than other species of the natural enemy complex. However, larger populations of Bph are fiercely attacked and effectively controlled by rapidly recruited ant workers; whereas, in the absence of the ant, the other natural enemies are inadequate. In normal circumstances, there is no ant recruitment in response to initially small populations of immigrant Bph and no evidence of incompatibility between ant foragers and other natural enemies such as spiders. However, when many ants are quickly and aggressively recruited to attack large populations of Bph, they temporarily displace some spiders from infested hills. It is concluded that, in suitable weather conditions and even when insecticides kill natural enemies within the rice field, periodic drainage that enables S. geminata to join the predator complex is valuable for ant-based control of pests such as snails and Lepidoptera, and especially against relatively large populations of Bph. Drainage practices to benefit ants are fully compatible with recent research, which shows that periodic drainage combats problems of 'yield decline' in intensively irrigated

The assessment of science: the relative merits of post-publication review, the impact factor, and the number of citations.

Science.gov (United States)

Eyre-Walker, Adam; Stoletzki, Nina

2013-10-01

The assessment of scientific publications is an integral part of the scientific process. Here we investigate three methods of assessing the merit of a scientific paper: subjective post-publication peer review, the number of citations gained by a paper, and the impact factor of the journal in which the article was published. We investigate these methods using two datasets in which subjective post-publication assessments of scientific publications have been made by experts. We find that there are moderate, but statistically significant, correlations between assessor scores, when two assessors have rated the same paper, and between assessor score and the number of citations a paper accrues. However, we show that assessor score depends strongly on the journal in which the paper is published, and that assessors tend to over-rate papers published in journals with high impact factors. If we control for this bias, we find that the correlation between assessor scores and between assessor score and the number of citations is weak, suggesting that scientists have little ability to judge either the intrinsic merit of a paper or its likely impact. We also show that the number of citations a paper receives is an extremely error-prone measure of scientific merit. Finally, we argue that the impact factor is likely to be a poor measure of merit, since it depends on subjective assessment. We conclude that the three measures of scientific merit considered here are poor; in particular subjective assessments are an error-prone, biased, and expensive method by which to assess merit. We argue that the impact factor may be the most satisfactory of the methods we have considered, since it is a form of pre-publication review. However, we emphasise that it is likely to be a very error-prone measure of merit that is qualitative, not quantitative.

Pseudomonas aeruginosa adaptation to lungs of cystic fibrosis patients leads to lowered resistance to phage and protist enemies.

Directory of Open Access Journals (Sweden)

Ville-Petri Friman

Full Text Available Pathogenic life styles can lead to highly specialized interactions with host species, potentially resulting in fitness trade-offs in other ecological contexts. Here we studied how adaptation of the environmentally transmitted bacterial pathogen, Pseudomonas aeruginosa, to cystic fibrosis (CF patients affects its survival in the presence of natural phage (14/1, ΦKZ, PNM and PT7 and protist (Tetrahymena thermophila and Acanthamoebae polyphaga enemies. We found that most of the bacteria isolated from relatively recently intermittently colonised patients (1-25 months, were innately phage-resistant and highly toxic for protists. In contrast, bacteria isolated from long time chronically infected patients (2-23 years, were less efficient in both resisting phages and killing protists. Moreover, chronic isolates showed reduced killing of wax moth larvae (Galleria mellonella probably due to weaker in vitro growth and protease expression. These results suggest that P. aeruginosa long-term adaptation to CF-lungs could trade off with its survival in aquatic environmental reservoirs in the presence of microbial enemies, while lowered virulence could reduce pathogen opportunities to infect insect vectors; factors that are both likely to result in poorer environmental transmission. From an applied perspective, phage therapy could be useful against chronic P. aeruginosa lung infections that are often characterized by multidrug resistance: chronic isolates were least resistant to phages and their poor growth will likely slow down the emergence of beneficial resistance mutations.

In this study the effectiveness of augmentative biological control techniques to control the two main strawberry (Fragaria xananassa Duchesne pest: the two-spotted spider mite (TSSM, Tetranychus urticae Koch (Acari: Tetranychidae, and the western flower thrips (WFT, Frankliniella occidentalis (Pergande (Thysanoptera: Thripidae, through releases of the predatory mites Phytoseiulus persimilis Athias-Henriot, Neoseiulus californicus (McGregor, Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae, and Orius laevigatus (Fieber (Heteroptera: Anthocoridae were tested. Two-year results on the performance of treatments using combinations of these biocontrol agents are presented. In both years, all treatments resulted in the reduction of TSSM numbers; but no treatment was better than the release of P. persimilis alone (P < 0.05. TSSM suppression varied among crop phases being greater early in the season. None of the treatments reduced significantly WFT numbers (P < 0.05, and the established economic injury level (EIL was surpassed from March to late April in both years. However, EIL was surpassed less times when treatment included O. laevigatus (2009: 20.7%; 2010: 22.7% of samples. No effect of A. swirskii was observed when this mite was released. Results corroborate that biological control techniques for TSSM and WFT are feasible for high-plastic tunnel strawberries. Under the conditions in our study no additive effects were observed, and there was not advantage in the release of multiple natural enemies.

Remembering Independence, Desiring Enemies: Reflections on Nationhood in Contemporary Lithuania

Directory of Open Access Journals (Sweden)

Ignas Kalpokas

2012-06-01

Full Text Available The paper addresses the remembrance of events surrounding the restoration of Lithuanian independence, as well as their repercussions on the present, concentrating on the younger generation that does not have first-hand experience of the period and, therefore, has to rely on other people’s accounts, textbooks, and other sources.If one considers the state and, especially, its social (or communal dimension as impossible totalities, memory and history acquire significant importance as they both provide ‘a magma of significations’, out of which particular signifying structures are instituted in order to anchor meaning and exhort a unifying claim through dominant narratives that tend to subjugate the otherwise inevitable variety of discourses. The discourse of the Lithuanian history textbooks is analysed by outlining its emphasis on unity and self-sacrifice in 1988-1991, and by portraying the Lithuanian history as an unending struggle against enemies and their malevolent plots. Also, considering the accounts of young people, two tendencies are visible: first, a bias towards images of unity and self-sacrifice depicting the period concerned, second, the predilection to employ the categories of ‘aliens’ and ‘enemies’ is evident, significantly affecting perceptions of the present with widespread images of disintegration and decay in the absence of the Other.

Prior to September 11, 2001, both were facing enormous difficulties in keeping their appeal as compelling discourses within their respective societies. Nevertheless, 9-11 revived neoconservatism by giving them the ideological enemy neoconservatives were longing calling for, leading to the invasion of Iraq on March 20, 2003 which, in turn, reenergized global jihadism.   Em termos ideológicos, a Guerra do Iraque foi resultado do encontro entre jihadismo global e neoconservadorismo.

The objective of this study was to determine the toxicity of the nine synthetic dienamides against the insect pest Diaphania hyalinata (melonworm) and the selectivity of these substances for the predator Solenopsis saevissima (fire ant). Four bioassays were conducted. To begin with, the dienamides that caused high mortality of D. hyalinata have been selected. In the second bioassay the dose-mortality curves of the selected dienamides have been constructed. In the third bioassay, the survival curves for D. hyalinata and the elapsed time to kill 50% of their population have been determined. In the fourth biological test, the selectivity of the substances to the predator S. saevissima has been evaluated. The most active (2E,4E)-N-butylhexa-2,4-dienamide 3d has killed 95% of the melonworm, D. hyalinata, and less than 10% of the natural enemy S. saevissima. The results presented by this compound are superior to the outcome displayed by the commercial insecticide Malathion®. Three of the dienamides prepared in this manuscript have proven to be selective in killing the pest, but not the beneficial insect.

Full Text Available We review the fire ant research conducted by the ARS-South American Biological Control Laboratory (SABCL since 1987 to find a complex of natural enemies in southern South America and evaluate their specificity and suitability for field release as self-sustaining biological control agents. We also include those studies conducted by the ARS-Center for Medical, Agriculture, and Veterinary Entomology in the United States with the SABCL collaboration. Ecological and biological information is reported on local fire ants and their microsporidia, nematodes, viruses, phorid flies, eucharitid wasps, strepsiptera, and parasitic ants. Their biology, abundance, distribution, detrimental effect, field persistence, specificity, and phenology are discussed. We conclude that the objectives of the ARS program in South America are being achieved and that the pioneering studies have served to encourage further investigations in the United States and other countries and advanced the implementation of biological control programs to decrease imported fire ant densities and damage. Still, several promising organisms should be further investigated for eventual field release in the near future.

Marigold (Tagetes erecta L. as an attractive crop to natural enemies in onion fields Cravo-de-defunto (Tagetes erecta L. como cultura atrativa para inimigos naturais em cultivo de cebola

Full Text Available Onion is the third most grown vegetable crop in São Paulo state, Brazil. Organic onion farming is expected to increase in the state due to the increasing demand. Pest management in organic onion farming is based on plant extracts with insecticide effects. However, the efficacy of such plant extracts has not been proved yet, and it was observed that they do negatively affect natural enemies. Plants surrounding onion fields, and that are attractive to natural enemies, may be a good option to farmers, since they may lead to increased diversity of arthropod species and, consequently, the natural control of pest populations. This study deals with the effect of marigold plants as a resource plant to natural enemies in onion fields. The experiment was set in a certified organic farm using marigold rows at a center of an onion field. Samples were taken from marigold and the onion plants 5 m (near and 30 m (far from the flowering strips. Higher numbers of arthropod pests were observed in onion plants 30 m from the marigold strip, while higher numbers of predators and parasitoids were found at 5 m distance. Species richness and Shannon's diversity index were higher at 5 m from marigold. Therefore, marigold rows next to onion fields resulted in higher number of entomophagous species, potentially enhancing the natural control of onion pests. In the study field, marigold strips may be an alternative to crop sprays for organic control of onion pests.A cebola é a terceira hortaliça mais cultivada em São Paulo, cujo cultivo orgânico tende a crescer devido ao grande mercado consumidor existente.

A utilização de plantas atrativas a inimigos naturais no entorno dos cultivos de cebola pode ser uma boa opção para os produtores, pois potencialmente aumentam a diversidade

``Sleeping with the enemy''—predator-induced diapause in a mite

Kroon, Annemarie; Veenendaal, René L.; Bruin, Jan; Egas, Martijn; Sabelis, Maurice W.

2008-12-01

Diapause in arthropods is a physiological state of dormancy that is generally thought to promote survival during harsh seasons and dispersal, but it may also serve to avoid predation in space and time. Here, we show that predation-related odours induce diapause in female adult spider mites. We argue that this response allows them to move into an area where they are free of enemies, yet forced to survive without food. Spider mites are specialised leaf feeders, but—in late summer—they experience severe predation on leaves. Hence, they face a dilemma: to stay on the leaf and risk being eaten or to move away from the leaf and risk death from starvation and thirst. Female two-spotted spider mites solve this dilemma by dramatically changing their physiology when exposed to predation-associated cues. This allows them to disperse away from leaves and to survive in winter refuges in the bark of trees or in the soil. We conclude that the mere presence of predation-associated cues causes some herbivorous mites to seek refuge, thereby retarding the growth rate of the population as a whole: a trait-mediated indirect effect that may have consequences for the stability of predator prey systems and for ecosystem structure.

[Love on enemy territory: Belgrade, Cetinje and Lublin under Austro-Hungarian occupation in World War I].

Science.gov (United States)

Scheer, Tamara

2015-01-01

During World War I, Serbia and Montenegro were under Austro-Hungarian occupation between late 1915/early 1916 and 1918. This article explores the attitude of the occupiers towards prostitution and venereal disease, among the indigenous population as well as among their own soldiers, officers and female support staff. The measures taken were primarily guided by military considerations. For the military, the occupied areas were zones that served particular purposes, such as preserving peace and order behind the front, making use of manpower and resources, and serving as cordon sanitaire. In spite of this, pseudo-peace-like structures evolved in the capitals Belgrade and Cetinje that facilitated the spread of prostitution and venereal disease. In my article, I will look at the scale of the debate and of the proposed countermeasures. It is noticeable that women were usually branded as the perpetrators, while the soldiers were seen as the ones in need of protection. In spite of this, it is apparent how candidly the royal-imperial army dealt with the topic even though it went against the current ideas of morality. The social differentiation that was customary in the imperial and royal army applied here, too. Officers suffering from venereal disease had their own hospitals and brothels and were permitted leave more often (a fact that went against the purpose of these institutions). The topic also received publicity because the military physicians, who were in fact civilians mobilized by the army, chose to publish continuously on the topic. Based on the microcosm of occupied enemy territory, my contribution shows how ideas of morality changed during the war despite traditional gender stereotypes, and the role played by the military in these developments.

Sugarcane Aphid Population Growth, Plant Injury, and Natural Enemies on Selected Grain Sorghum Hybrids in Texas and Louisiana.

In response to the 2013 outbreak of sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae), on sorghum, Sorghum bicolor (L.), in North America, experiments were conducted at three southern U.S. grain sorghum production locations (Corpus Christi, TX; Winnsboro, LA; Rosenberg, TX). The objectives were to authenticate yield decline on susceptible hybrids (2014 and 2015) and to measure aphid population growth and natural enemy prevalence on susceptible and resistant hybrids with similar genetic background (2014). Yield decline on susceptible hybrids (Tx 2752/Tx430 and DKS53-67) was more substantial when aphid population growth accelerated quickly and peaked above 300 aphids per leaf (50 to nearly 100% yield decline). Location and year variation in maximum aphid density and cumulative aphid-days was high, with doubling time values on the susceptible hybrids ranging between 3.9 and 7.9 d. On resistant Tx2752/Tx2783, leaf injury and yield decline were not seen or less severe than on its paired susceptible Tx2752/Tx430. Aphids declined on Tx2752/Tx2783 after initial colony establishment (Corpus Christi) or took about 60% longer to double in population size when compared with Tx2572/Tx430 (Winnsboro). The predominant natural enemy taxa were aphelinid mummies (Hymenoptera: Aphelinidae), ladybird beetles (Coleoptera: Coccinellidae), and sryphid flies (Diptera: Syrphidae), and they were more prevalent during flowering than prior to flowering. They were generally responsive to changes in aphid density of both susceptible and resistant hybrids, but variability points to need for further study. In future research, full season observations should continue as well as more detailed study of potential compatibility of sorghum resistance and biological control. © The Author 2017.

Habitat management involving conservative biological control could be a good crop pest management option in poor African countries. A survey was conducted from August 2013 to July 2014 in a rainfed lowland region near Pélébina, northern Benin, in order to characterize spatiotemporal landscape changes and investigate their influence on the main crop pests and their associated natural enemies. The area was mapped mainly regarding crop fields and fallows. Visual observations were recorded and a database was compiled. Major landscape composition changes were noted between rainy and dry seasons, which affected the presence of both pests and natural enemies. Cereals (rice, maize and sorghum) and cotton were grown in the humid season, and then okra (Abelmoschus esculentus) was the dominant vegetable crop in dry season. These modifications impacted fallow abundance throughout the lowland. Different cotton (e.g. Helicoverpa armigera, Dysdercus sp., Zonocerus variegatus) or rice (e.g. Diopsis longicornis, D. apicalis) pests were observed during dry season in okra crops. Dry season surveys of Poaceae in two types of fallows ('humid', 'dry') revealed the presence of very few stem borers: only 0.04% of stems sampled were infested by stem borers, with a mean of 1.13 larvae per stem. Known cereal stem borer species such as Busseola fusco, Coniesta ignefusalis, Sesamia calamistis were not clearly identified among these larvae because of their diapausing stage and white color. Unexpected pollinators (Hymenoptera Apidae, genus Braunsapis, Ceratina and Xylocopa) and predators (Crabronidae, genus Dasyproctus) were found in the stems. Sweep-net collection of insects in humid fallows allowed us to describe for the first time in Benin seven Diopsidae species (23% of adults bearing Laboulbeniomycetes ectoparasitic fungi). Some of these species were captured in rice fields during rainy season. Parasitoids (adult Chalcidoidae and Ichneumonoidae) were observed during both seasons but their

The enemy within: Power and politics in the transition to nurse practitioner

Directory of Open Access Journals (Sweden)

Lorna MacLellan

Full Text Available Background: The period of transition from registered nurse to nurse practitioner is often challenging. While adjusting to their autonomous role, nurse practitioners need to create and define a distinct role for themselves within practice contexts that may be unfamiliar, sometimes unwelcoming and inhospitable. During this time of transition, nurses need well developed negotiation skills and personal attributes including resilience, tenacity, fortitude and determination. Purpose of the research: The purpose of the research reported in this paper was to explore the transition experiences of 10 newly endorsed nurse practitioners in Australia during their first year of practice. This paper focuses on power, control and political manoeuvring that negatively impacted the ׳nurse practitioners׳ transition. A qualitative approach using a modified version of Carspecken׳s five stage critical ethnography, informed by focused ethnography, was the methodology selected for this study. Methods included observations of practice, journaling, face to face and phone interviews which were recorded, transcribed and analysed thematically. Results: “The enemy within” emerged as a dominant theme highlighting issues of power, powerlessness and politics dominating the participant׳s experiences. Power struggles amongst nurses, both overt and covert, and the deliberate misuse of power were frequently encountered. Many of the participants felt powerless and ill-prepared to negotiate the challenging situations in which they found themselves. Many lacked the skills needed to address the negative behaviours they experienced. Conclusions: This paper reports on the experiences of 10 newly endorsed nurse practitioners during their transition to the nurse practitioner role. The impact of the political climate at the time of this study had an undeniable influence on many of the participants׳ transition experiences. Competition for the limited numbers of

Habitat affinity of resident natural enemies of the invasive Aphis glycines (Hemiptera: Aphididae), on soybean, with comments on biological control.

Brewer, Michael J; Noma, Takuji

2010-06-01

We integrated a natural enemy survey of the broader landscape into a more traditional survey for Aphis glycines Matsumura (Hemiptera: Aphididae), parasitoids and predatory flies on soybean using A. glycines-infested soybean, Glycine max (L.) Merr., placed in cropped and noncropped plant systems to complement visual field observations. Across three sites and 5 yr, 18 parasitoids and predatory flies in total (Hymenoptera: Aphelinidae [two species] and Bracondae [seven species], Diptera: Cecidomyiidae [one species], Syrphidae [seven species], Chamaemyiidae [one species]) were detected, with significant variability in recoveries detected across plant system treatments and strong contrasts in habitat affinity detected among species. Lysiphlebus testaceipes Cresson was the most frequently detected parasitoid, and no differences in abundance were detected in cropped (soybean, wheat [Triticum aestivum L.], corn [Zea mays L.], and alfalfa [Medicago sativa L.]) and noncropped (poplar [Populus euramericana (Dode) Guinier] and early successional vegetation) areas. In contrast, Binodoxys kelloggensis Pike, Starý & Brewer had strong habitat affinity for poplar and early successional vegetation. The low recoveries seasonally and across habitats of Aphelinus asychis Walker, Aphelinus sp., and Aphidius colemoni Viereck make their suitability to A. glycines on soybean highly suspect. The widespread occurrence of many of the flies reflects their broad habitat affinity and host aphid ranges. The consistent low field observations of parasitism and predation suggest that resident parasitoids and predatory flies are unlikely to contribute substantially to A. glycines suppression, at least during the conventional time period early in the pest invasion when classical biological control activities are considered. For selected species that were relatively well represented across plant systems (i.e., L. testaceipes and Aphidoletes aphidimyza Rondani), conservation biological control efforts

Nanotechnology will be an increasing part of the everyday lives of most people in the world. There is a general recognition that few people understand the implications of the technology, the technology itself or even the definition of the word. This lack of understanding stems from a lack of knowledge about science in general but more specifically difficulty in grasping the size scale and symbolism of nanotechnology. A potential key to informing the general public is establishing the ability to comprehend the scale of nanotechnology. Transitioning from the macro to the nanoscale seems to require an ability to comprehend scales of one-billion. Scaling is a skill not common in most individuals and tests of their ability to extrapolate size based upon scaling a common object demonstrates that most individuals cannot scale to the extent needed to make the transition to nanoscale. Symbolism is another important vehicle to providing the general public with a basis to understand the concepts of nanotechnology. With increasing age, individuals are able to draw representations of atomic scale objects, but these tend to be iconic and the different representations not easily translated. Ball and stick models are most recognized by the public, which provides an opportunity to present not only useful symbolism but also a reference point for the atomic scale.

With increasing age, individuals are able to draw representations of atomic scale objects, but these tend to be iconic and the different representations not easily translated. Ball and stick models are most recognized by the public, which provides an opportunity to present not only useful symbolism but also a reference point for the atomic scale.

Timely publication of data is important for the medical community and provides a valuable contribution to data disclosure. The objective of this study was to identify and evaluate times to acceptance and publication for peer-reviewed manuscripts, reviews, and letters to the editor. Key publication metrics for published manuscripts, reviews, and letters to the editor were identified by eight Amgen publications professionals. Data for publications submitted between 1 January 2013 and 1 November 2015 were extracted from a proprietary internal publication-tracking database. Variables included department initiating the study, publication type, number of submissions per publication, and the total number of weeks from first submission to acceptance, online publication, and final publication. A total of 337 publications were identified, of which 300 (89%) were manuscripts. Time from submission to acceptance and publication was generally similar between clinical and real-world evidence (e.g. observational and health economics studies) publications. Median (range) time from first submission to acceptance was 23.4 (0.2-226.2) weeks. Median (range) time from first submission to online (early-release) publication was 29.7 (2.4-162.6) weeks. Median (range) time from first submission to final (print) publication was 36.2 (2.8-230.8) weeks. Time from first submission to acceptance, online publication, and final publication increased accordingly with number of submissions required for acceptance, with similar times noted between each subsequent submission. Analysis of a single-company publication database showed that the median time for manuscripts to be fully published after initial submission was 36.2 weeks, and time to publication increased accordingly with the number of submissions. Causes for multiple submissions and time from clinical trial completion to first submission were not assessed; these were limitations of the study. Nonetheless, publication planners should consider

Problems Inherent to Augmentation of Natural Enemies in Open Agriculture.

2018-04-01

Augmentation biological control has successfully replaced a lot of insecticide use in 'closed system' agriculture (e.g., greenhouses). The profitable commercialization of biocontrol agents in greenhouses has created an incentive to expand markets for mass-reared beneficial insects into open agricultural systems, often without sufficient scientific justification. However, the semi-contained nature of greenhouse culture is often critical to the success of augmentation and can serve to mask potential pitfalls and intrinsic limitations of this approach in open systems. Factors contributing to greenhouse successes include the reduced biological diversity of contained agroecosystems, the prevention of agent dispersal, the ability to maintain environmental conditions within a range favorable for the agent, the exclusion of competitors and natural enemies of the agent that might otherwise diminish its efficacy, and the absence of alternative prey/hosts that could divert predation/parasitism from the target pest. There are also problems arising from collection of source material from locally adapted populations, and the inadvertent imposition of artificial selection in the course of laboratory rearing. Besides highlighting these pitfalls, this paper aims to encourage more consideration of conservation approaches prior to investment in augmentation programs which entice farmers into perpetual cycles of 'rear and release.' I argue that although augmentation can benefit agriculture whenever it replaces pesticide applications, it does not constitute an ecologically sustainable solution because it requires continued inputs, and it can distract research attention away from more sustainable objectives. Sustainable biological control is best achieved through modifications to cultural practices that increasingly 'naturalize' agroecosystems, thus facilitating the natural recruitment and persistence of beneficial arthropod fauna, combined with habitat management geared to increasing

Within-crop habitat manipulations have the potential to increase the biological control of pests in horticultural field crops. Wildflower strips have been shown to increase the abundance of natural enemies, but there is little evidence to date of an impact on pest populations. The aim of this study was to determine whether within-crop wildflower strips can increase the natural regulation of pests in horticultural field crops. Aphid numbers in plots of lettuce grown adjacent to wildflower strips were compared with those in plots grown in the absence of wildflowers. The presence of wildflower strips led to a decrease in aphid numbers on adjacent lettuce plants during June and July, but had less impact in August and September. The decrease in aphid numbers was greatest close to the wildflower strips and, the decrease in aphid numbers declined with increasing distance from the wildflower strips, with little effect at a distance of ten metres. The main natural enemies found in the crop were those that dispersed aerially, which is consistent with data from previous studies on cereal crops. Analysis and interpretation of natural enemy numbers was difficult due to low recovery of natural enemies, and the numbers appeared to follow changes in aphid abundance rather than being directly linked to the presence of wildflower strips. Cutting the wildflower strips, to remove floral resources, had no impact on the reduction in aphid numbers achieved during June and July, but decreased the effect of the wildflower strips during August and September. The results suggest that wildflower strips can lead to increased natural regulation of pest aphids in outdoor lettuce crops, but more research is required to determine how this is mediated by natural enemies and how the impact of wildflower strips on natural pest regulation changes during the growing season.

Enemy at the gates: Rapid defensive trait diversification in an adaptive radiation of lizards.

2016-11-01

Adaptive radiation (AR), the product of rapid diversification of an ancestral species into novel adaptive zones, has become pivotal in our understanding of biodiversity. Although it has widely been accepted that predators may drive the process of AR by creating ecological opportunity (e.g., enemy-free space), the role of predators as selective agents in defensive trait diversification remains controversial. Using phylogenetic comparative methods, we provide evidence for an "early burst" in the diversification of antipredator phenotypes in Cordylinae, a relatively small AR of morphologically diverse southern African lizards. The evolution of body armor appears to have been initially rapid, but slowed down over time, consistent with the ecological niche-filling model. We suggest that the observed "early burst" pattern could be attributed to shifts in vulnerability to different types of predators (i.e., aerial versus terrestrial) associated with thermal habitat partitioning. These results provide empirical evidence supporting the hypothesis that predators or the interaction therewith might be key components of ecological opportunity, although the way in which predators influence morphological diversification requires further study. © 2016 The Author(s).

Internal medicine fellowship programs have an incentive to select fellows who will ultimately publish. Whether an applicant's publication record predicts long term publishing remains unknown. Using records of fellowship bound internal medicine residents, we analyzed whether publications at time of fellowship application predict publications more than 3 years (2 years into fellowship) and up to 7 years after fellowship match. We calculate the sensitivity, specificity, positive and negative predictive values and likelihood ratios for every cutoff number of application publications, and plot a receiver operator characteristic curve of this test. Of 307 fellowship bound residents, 126 (41%) published at least one article 3 to 7 years after matching, and 181 (59%) of residents do not publish in this time period. The area under the receiver operator characteristic curve is 0.59. No cutoff value for application publications possessed adequate test characteristics. The number of publications an applicant has at time of fellowship application is a poor predictor of who publishes in the long term. These findings do not validate the practice of using application publications as a tool for selecting fellows.

[Public health services between "new public health" and "new public management"].

Science.gov (United States)

Oppen, M

1996-04-01

Today, a substantial reorientation of the Public Health services in the Federal Republic of Germany is broadly seen necessary. Patterns of functional and organisational restructuring of Public Health services on the regional and the communal level are closely linked with concepts of prevention and health promotion. Hence, a number of agencies have already adopted new tasks and functions like comprehensive and transorganizational planning, coordination and evaluation as well as the establishment of new reporting systems. Presently, the transformation process from the bureaucratic mode of administering matters of health to a new Public Health orientation receives new impacts from the international "New Public Management" movement. Comparatively late, with the beginning of the 1990s, a growing number of German municipalities has introduced new concepts of administration. Local government administrations, of which the Public Health services are a part, follow the model of modern service organizations producing services in a more efficient, professionalized and consumer-oriented way. Specific elements of economising modernisation programmes like re-distribution of tasks, de-centralisation, extension of managerial capacities, setting of stimulating working conditions that provide employees with greater independence of action as well as career opportunities, are at the same time prerequisites for innovative strategies of health protection and coordination policies of Public Health services.

To estimate the effect of opening two services for people who use drugs and three police interventions on the number of discarded syringes collected from public spaces in Barcelona between 2004 and 2014. We conducted an interrupted time-series analysis of the monthly number of syringes collected from public spaces during this period. The dependent variable was the number of syringes collected per month. The main independent variables were month and five dummy variables (the opening of two facilities with safe consumption rooms, and three police interventions). To examine which interventions affected the number of syringes collected, we performed an interrupted time-series analysis using a quasi-Poisson regression model, obtaining relative risks (RR) and 95% confidence intervals (CIs). The number of syringes collected per month in Barcelona decreased from 13,800 in 2004 to 1655 in 2014 after several interventions. For example, following the closure of an open drug scene in District A of the city, we observed a decreasing trend in the number of syringes collected [RR=0.88 (95% CI: 0.82-0.95)], but an increasing trend in the remaining districts [RR=1.11 (95% CI: 1.05-1.17) and 1.08 (95% CI: 0.99-1.18) for districts B and C, respectively]. Following the opening of a harm reduction facility in District C, we observed an initial increase in the number collected in this district [RR=2.72 (95% CI: 1.57-4.71)] and stabilization of the trend thereafter [RR=0.97 (95% CI: 0.91-1.03)]. The overall number of discarded syringes collected from public spaces has decreased consistently in parallel with a combination of police interventions and the opening of harm reduction facilities.

Winter: Public Enemy #1 for Accessibility EXPLORING NEW SOLUTIONS

Directory of Open Access Journals (Sweden)

Ernesto Morales

2014-05-01

Full Text Available Abstract: Winter is expensive. For countries situated in the northern hemisphere, closer to the north pole, such as Canada, Russia and Scandinavia, winter requires the acquisition of special clothing, car tires, and sports equipment, snow removal or plowing from the streets, and is associated with the presence of ice patches, along with accidents and illnesses associated with cold weather. Fall-related injuries due to winter conditions have been estimated to cost the Canadian health care system $ 2.8 billion a year. However, the greatest cost snow entails every year is the social isolation of seniors as well as wheelchair and walker users. This results from the lack of accessibility, as it is difficult to circulate on snow-covered streets even for the able-bodied. Social isolation has been associated with other negative consequences such as depression and even suicide. This exploratory pilot study aimed at finding possible and feasible design solutions for improving the accessibility of sidewalks during winter conditions. For this project we used a Co-Design methodology. Stakeholders (City of Quebec representatives, designers, urban planners, occupational therapists, and adults with motor, visual and aural disabilities were invited to participate in the design process. In order to meet the objectives, two main steps were carried out: 1. Conception of the design solutions (through Co-design sessions in a Focus-group format with seniors, designers and researchers; and 2. Validation of the design solutions (consultation with experts and stakeholders. The results are a wide variety of possible and feasible solutions, including the reorganisation of the snow-removal procedure and the development of heated curb cuts. This project was funded by the City of Quebec in partnership with the Centre interdisciplinaire de recherche en réadaptation et intégration sociale (CIRRIS. Ultimately, the project sought to explore possible solutions to be implemented, if feasible, in the future by the municipal government.

Landscape and biodiversity as new resources for agro-ecology? Insights from farmers' perspectives

Directory of Open Access Journals (Sweden)

Nicolas Salliou

2017-06-01

Full Text Available Pesticide reduction is a key current challenge. Scientific findings in landscape ecology suggest that complex landscapes favor insect pest biological control by conservation of natural enemy habitats. A potential agro-ecological innovation is to conserve or engineer such complex landscapes to reduce pesticide use. However, whereas the relevant resources are often well known in most natural resource management situations, potential resources involved in this innovation (natural enemies and the landscape are not necessarily considered as resources in the eyes of their potential users. From the perspective that resources are socially constructed, our objective was to investigate whether and how these resources are considered by their potential users. To do so, we conducted research in an area specializing in tree-fruit (apple production in southwestern France. This site was selected for its high pest incidence and high use of insecticides on orchards and, consequently, high stakes involved for any alternative. We conducted 30 comprehensive interviews with stakeholders (farmers and crop advisors about their pest control strategies to explore their representation of their landscape and natural enemies. Our results show that natural enemies are considered by local stakeholders as public good resources, especially in the context of interventions by public institutions for their conservation, acclimation, and management. Farmers sometimes consider natural enemies as private goods when they can isolate the crop, enclosing it with nets or some other type of boundary. We also show that the landscape was not considered as a resource for biological pest control by conservation, but rather as a source of pests. We advocate for more research on the effects of landscapes on natural enemies, including participatory research based on dialogue among farmers, crop advisors, and scientists.

Full Text Available The study of the relationship between species or populations is an excellent tool to learn about ecological phenomena. Among the possible interaction between two species, it is highlighted the mutualism between ants and insects that produce honeydew. While honeydew is "garbage" for the aphids it can be a food source for ants. The type of interaction between aphids and their natural enemies, known as "intraguild predation" or predation of natural enemies that share the same prey is an interaction that occurs in aphid communities. The majority of natural enemies in this system interact asymmetrically according to differences in body size, feeding strategy and priorities of each species. In agroecosystems, the consequence of this relation becomes particularly important for the biological control of pests of economic importance. In Brazil, few publications refer to the association among ants, aphids and their natural enemies, specifically in forest areas. Thus, this work had the objective to review studies regarding these association and discuss a field observed case involving the giant conifer aphid, Cinara atlantica (Hemiptera: Aphididae, its natural enemies and the ants Solenopsis invicta and Camponotus rufipes, occurring on Pinus taeda.

Insecticides suppress natural enemies and increase pest damage in cabbage.

Bommarco, Riccardo; Miranda, Freddy; Bylund, Helena; Björkman, Christer

2011-06-01

Intensive use of pesticides is common and increasing despite a growing and historically well documented awareness of the costs and hazards. The benefits from pesticides of increased yields from sufficient pest control may be outweighed by developed resistance in pests and killing of beneficial natural enemies. Other negative effects are human health problems and lower prices because of consumers' desire to buy organic products. Few studies have examined these trade-offs in the field. Here, we demonstrate that Nicaraguan cabbage (Brassica spp.) farmers may suffer economically by using insecticides as they get more damage by the main pest diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), at the same time as they spend economic resources on insecticides. Replicated similarly sized cabbage fields cultivated in a standardized manner were either treated with insecticides according common practice or not treated with insecticides over two seasons. Fields treated with insecticides suffered, compared with nontreated fields, equal or, at least in some periods of the seasons, higher diamondback moth pest attacks. These fields also had increased leaf damage on the harvested cabbage heads. Weight and size of the heads were not affected. The farmers received the same price on the local market irrespective of insecticide use. Rates of parasitized diamondback moth were consistently lower in the treated fields. Negative effects of using insecticides against diamondback moth were found for the density of parasitoids and generalist predatory wasps, and tended to affect spiders negatively. The observed increased leaf damages in insecticide-treated fields may be a combined consequence of insecticide resistance in the pest, and of lower predation and parasitization rates from naturally occurring predators that are suppressed by the insecticide applications. The results indicate biological control as a viable and economic alternative pest management strategy

2011-03-15

To meet challenges arising from increasing rates of noncoverage in US landline-based telephone samples due to cell-phone-only households, the Behavioral Risk Factor Surveillance System (BRFSS) expanded a traditional landline-based random digit dialing survey to a dual-frame survey of landline and cell phone numbers. In 2008, a survey of adults with cell phones only was conducted in parallel with an ongoing landline-based health survey in 18 states. The authors used the optimal approach to allocate samples into landline and cell-phone-only strata and used a new approach to weighting state-level landline and cell phone samples. They developed logistic models for each of 16 health indicators to examine whether exclusion of adults with cell phones only affected estimates after adjustment for demographic characteristics. The extents of the potential biases in landline telephone surveys that exclude cell phones were estimated. Biases resulting from exclusion of adults with cell phones only from the landline-based survey were found for 9 out of the 16 health indicators. Because landline noncoverage rates for adults with cell phones only continue to increase, these biases are likely to increase. Use of a dual-frame survey of landline and cell phone numbers assisted the BRFSS efforts in obtaining valid, reliable, and representative data.

FINANCING PUBLIC TRANSPORT SERVICES FROM PUBLIC FUNDS

Directory of Open Access Journals (Sweden)

Miloš POLIAK

2017-12-01

Full Text Available The paper deals with the issue of efficiency of public passenger transport through financial support from public funds from the perspective of improving road safety. The aim is to verify the hypothesis that financing public passenger transport from public funds is a significant tool to influence the number of passengers carried by individual automobile transport, and thus it can be used a tool for influencing road safety in a particular territory. The first part of the paper analyses the sources for financial support of public passenger transport. The next part describes the assumptions for improving road safety through increasing the support of public passenger transport. The last part analyses possible impacts of financing public passenger transport on the road safety in relation to the specified hypothesis.

Public Sector Unions and Privatization

DEFF Research Database (Denmark)

Foged, Søren Kjær; Aaskoven, Lasse

Privatization varies considerably among local governments. One of the oft-listed explanations is the ability of public employees to block privatization. However, many studies on the influence of public employees on privatization do not use very precise measures of the influence of public employees...... Danish municipalities in 2012, we are able to measure the strength of the public eldercare union as well as the number of the public eldercare workers relative to the number of local voters. We find that the increased union strength measured in terms of union density at the municipal level leads...... to substantially and significantly less privatization through the voucher market. By comparison, the estimated relationship between the relative number of public workers and privatization does not reach statistical significance. Features of the voucher market and qualitative evidence suggest that the union...

It is unclear if preresidency and/or residency research work impacts academic neurosurgery placement post residency. The goal of this study is to evaluate the impact that preresidency and residency research publication has on attaining academic faculty positions. Alumni information was collected from 65 of the 108 (60%) neurosurgery residency websites. Graduates from these programs between 2005 and 2015 (n = 949) were analyzed to determine factors associated with an academic career. Information on publications, citations, and H-index were obtained from Web of Science. Current position was designated as academic if the physician had a teaching position at a university hospital and private if the physician was not affiliated with a university hospital. Univariate and multivariate logistic regression models were used to identify factors associated with academic faculty positions post residency. Of the 949 physicians included in the analysis, 339 (36%) were in academic positions, 518 (55%) in private practice, and 92 (10%) were still in training. More than a fifth (212, or 22%) of physicians performed a research fellowship (8.2%) or attained a Ph.D. (14.1%) during medical school. Among those who had completed training, an academic career was associated with having 2 or more publications during residency (odds ratio [OR] [95% confidence interval, CI]: 3.87 [1.59-9.45]; P < 0.003), H-index ≥ 2 during residency (OR [95% CI]: 2.32 [1.40-1.69]; P < 0.0001) and having devoted research time before residency (OR [95% CI]: 1.56 [1.10-2.22]; P < 0.012). Notably, publications before residency were not an independent indicator of academic placement. These findings may help guide residency programs to identify and/or cultivate neurosurgeons to become academic neurosurgeons. Copyright © 2017 Elsevier Inc. All rights reserved.

Connecting scales: achieving in-field pest control from areawide and landscape ecology studies.

Schellhorn, Nancy A; Parry, Hazel R; Macfadyen, Sarina; Wang, Yongmo; Zalucki, Myron P

2015-02-01

Areawide management has a long history of achieving solutions that target pests, however, there has been little focus on the areawide management of arthropod natural enemies. Landscape ecology studies that show a positive relationship between natural enemy abundance and habitat diversity demonstrate landscape-dependent pest suppression, but have not yet clearly linked their findings to pest management or to the suite of pests associated with crops that require control. Instead the focus has often been on model systems of single pest species and their natural enemies. We suggest that management actions to capture pest control from natural enemies may be forth coming if: (i) the suite of response and predictor variables focus on pest complexes and specific management actions; (ii) the contribution of "the landscape" is identified by assessing the timing and numbers of natural enemies immigrating and emigrating to and from the target crop, as well as pests; and (iii) pest control thresholds aligned with crop development stages are the benchmark to measure impact of natural enemies on pests, in turn allowing for comparison between study regions, and generalizations. To achieve pest control we will need to incorporate what has been learned from an ecological understanding of model pest and natural enemy systems and integrate areawide landscape management with in-field pest management. © 2014 Institute of Zoology, Chinese Academy of Sciences.

Rare fungal infectious agents: a lurking enemy [version 1; referees: 4 approved

Anna Skiada

2017-10-01

Full Text Available In the expanding population of immunocompromised patients and those treated in intensive care units, rare fungal infectious agents have emerged as important pathogens, causing invasive infections associated with high morbidity and mortality. These infections may present either as de novo or as breakthrough invasive infections in high-risk patients with hematologic malignancies receiving prophylactic or empirical antifungal therapy or in patients with central venous catheters. Diagnosis and treatment are challenging. Physicians should have a high index of suspicion because early diagnosis is of paramount importance. Conventional diagnostic methods such as cultures and histopathology are still essential, but rapid and more specific molecular techniques for both detection and identification of the infecting pathogens are being developed and hopefully will lead to early targeted treatment. The management of invasive fungal infections is multimodal. Reversal of risk factors, if feasible, should be attempted. Surgical debridement is recommended in localized mold infections. The efficacy of various antifungal drugs is not uniform. Amphotericin B is active against most yeasts, except Trichosporon, as well as against Mucorales, Fusarium, and some species of Paecilomyces and dimorphic fungi. The use of voriconazole is suggested for the treatment of trichosporonosis and scedosporiosis. Combination treatment, though recommended as salvage therapy in some infections, is controversial in most cases. Despite the use of available antifungals, mortality remains high. The optimization of molecular-based techniques, with expansion of reference libraries and the possibility for direct detection of resistance mechanisms, is awaited with great interest in the near future. Further research is necessary, however, in order to find the best ways to confront and destroy these lurking enemies.

State-certified occupational physicians who work as civil servants in the Federal Republic of Germany are key players in the German Public Health system. They control i.e. the legal compliance in occupational health and participate in the occupational disease procedures. Despite the role model function of the German Public health system for many developing countries, this area of Public health is debated to have been hampered in the past years by a disregard concerning structural developments. Different databases were screened for occupational health benchmarks. Obtained data were compared to socioeconomic data and indices were calculated. The overall numbers of State-certified occupational physicians decreased in Germany between 1992 and 2012 from 136 to 86 (63 %). On the single state level, the ratios of State-certified occupational physicians per 1 Mio. working population ranged from 8 for the state of Saarland to 0.8 for the state of North Rhine Westphalia. A general difference was found for old versus new German states. Also, large differences were present for the ratios of State-certified occupational physicians per 10 6 employees towards public debt per capita (€) and the ratios of State-certified occupational physicians per Gross Domestic Product (GDP) in the 16 German states in 2012. In striking contrast to the WHO document on the Occupational safety and health (OSH) system that states in its executive summary that the human and institutional capacities of the German occupational health system are very strong in both quantity and quality, we here show extreme imbalances present at the single state levels that developed over the past 20 years. With a regard to the increasing complexity of the economic system a reversal of this trend should be demanded.

Mosquitoes (Diptera: Culicidae) serve as important vectors for a wide number of parasites and pathogens of huge medical and veterinary importance. Aedes aegypti is a primary dengue vector in tropical and subtropical urban areas. There is an urgent need to develop eco-friendly mosquitocides. In this study, silver nanoparticles (AgNP) were biosynthesized using neem cake, a by-product of the neem oil extraction from the seed kernels of Azadirachta indica. AgNP were characterized using a variety of biophysical methods, including UV-vis spectrophotometry, FTIR, SEM, EDX, and XRD analyses. Furthermore, the neem cake extract and the biosynthesized AgNP were tested for acute toxicity against larvae and pupae of the dengue vector Ae. aegypti. LC50 values achieved by the neem cake extract ranged from 106.53 (larva I) to 235.36 ppm (pupa), while AgNP LC50 ranged from 3.969 (larva I) to 8.308 ppm (pupa). In standard laboratory conditions, the predation efficiency of a Carassius auratus per day was 7.9 (larva II) and 5.5 individuals (larva III). Post-treatment with sub-lethal doses of AgNP, the predation efficiency was boosted to 9.2 (larva II) and 8.1 individuals (larva III). The genotoxic effect of AgNP was studied on C. auratus using the comet assay and micronucleus frequency test. DNA damage was evaluated on peripheral erythrocytes sampled at different time intervals from the treatment; experiments showed no significant damages at doses below 12 ppm. Overall, this research pointed out that neem cake-fabricated AgNP are easy to produce, stable over time, and can be employed at low dosages to reduce populations of dengue vectors, with moderate detrimental effects on non-target mosquito natural enemies.

The number of scholarly documents available on the web is estimated using capture/recapture methods by studying the coverage of two major academic search engines: Google Scholar and Microsoft Academic Search. Our estimates show that at least 114 million English-language scholarly documents are accessible on the web, of which Google Scholar has nearly 100 million. Of these, we estimate that at least 27 million (24%) are freely available since they do not require a subscription or payment of any kind. In addition, at a finer scale, we also estimate the number of scholarly documents on the web for fifteen fields: Agricultural Science, Arts and Humanities, Biology, Chemistry, Computer Science, Economics and Business, Engineering, Environmental Sciences, Geosciences, Material Science, Mathematics, Medicine, Physics, Social Sciences, and Multidisciplinary, as defined by Microsoft Academic Search. In addition, we show that among these fields the percentage of documents defined as freely available varies significantly, i.e., from 12 to 50%. PMID:24817403

How geographically widespread biological communities assemble remains a major question in ecology. Do parallel population histories allow sustained interactions (such as host-parasite or plant-pollinator) among species, or do discordant histories necessarily interrupt them? Though few empirical data exist, these issues are central to our understanding of multispecies evolutionary dynamics. Here we use hierarchical approximate Bayesian analysis of DNA sequence data for 12 herbivores and 19 parasitoids to reconstruct the assembly of an insect community spanning the Western Palearctic and assess the support for alternative host tracking and ecological sorting hypotheses. We show that assembly occurred primarily by delayed host tracking from a shared eastern origin. Herbivores escaped their enemies for millennia before parasitoid pursuit restored initial associations, with generalist parasitoids no better able to track their hosts than specialists. In contrast, ecological sorting played only a minor role. Substantial turnover in host-parasitoid associations means that coevolution must have been diffuse, probably contributing to the parasitoid generalism seen in this and similar systems. Reintegration of parasitoids after host escape shows these communities to have been unsaturated throughout their history, arguing against major roles for parasitoid niche evolution or competition during community assembly.

Public consent for mining: An industry viewpoint

International Nuclear Information System (INIS)

Zelms, J.L.

1990-01-01

The predominance of the mining industry was never intentionally destructive to the environment. Even when laws and regulations were far more relaxed than they are today, our operations were conducted professionally, But when change came, mining companies took a noncooperative attitude. We knew that we were the mining experts and that regulators or lawmakers were not. And it became accepted in our industry to stonewall change -- not to work with regulators and lawmakers but to resist change. This same attitude spilled over into attitudes with the media. Reporters were percieved as the enemy and many felt the press misrepresented their views. So we didn't work with the media unless we absolutely had to. In the process, industry did not participate in establishing guidelines and criteria for environmental regulation. Business ceded the environmental agenda to others and we have ended up with laws that forced billions of dollars of expenditures without ensuring that those expenditures had maximum impact on environmental problems. New rules are written by people less knowledgeable about the industry, consequently they cost more than they should and may not even have the desired result. Companies end up spending more than if they had addressed the problem themselves originally. It is no longer enough merely to be mining professionals. Today, it's only a threshold requirement for enduring success. We will best earn public consent to operate by anticipating what society will expect of us and by working to meet those expectations. We must set our own public policy before they become law or regulation and before we are branded as nonresponsive and noncaring

Metagenomics and next generation sequencing were employed to discover new virus natural enemies of the fire ant, Solenopsis invicta Buren in its native range (i.e., Formosa, Argentina) with the ultimate goal of testing and releasing new viral pathogens into U.S. S. invicta populations to provide natural, sustainable control of this ant. RNA was purified from worker ants from 182 S. invicta colonies, which was pooled into 4 groups according to location. A library was created from each group and sequenced using Illumina Miseq technology. After a series of winnowing methods to remove S. invicta genes, known S. invicta virus genes, and all other non-virus gene sequences, 61,944 unique singletons were identified with virus identity. These were assembled de novo yielding 171 contiguous sequences with significant identity to non-plant virus genes. Fifteen contiguous sequences exhibited very high expression rates and were detected in all four gene libraries. One contig (Contig_29) exhibited the highest expression level overall and across all four gene libraries. Random amplification of cDNA ends analyses expanded this contiguous sequence yielding a complete virus genome, which we have provisionally named Solenopsis invicta virus 5 (SINV-5). SINV-5 is a positive-sense, single-stranded RNA virus with genome characteristics consistent with insect-infecting viruses from the family Dicistroviridae. Moreover, the replicative genome strand of SINV-5 was detected in worker ants indicating that S. invicta serves as host for the virus. Many additional sequences were identified that are likely of viral origin. These sequences await further investigation to determine their origins and relationship with S. invicta. This study expands knowledge of the RNA virome diversity found within S. invicta populations.

By-product mutualism and the ambiguous effects of harsher environments - A game-theoretic model.

Science.gov (United States)

De Jaegher, Kris; Hoyer, Britta

2016-03-21

We construct two-player two-strategy game-theoretic models of by-product mutualism, where our focus lies on the way in which the probability of cooperation among players is affected by the degree of adversity facing the players. In our first model, cooperation consists of the production of a public good, and adversity is linked to the degree of complementarity of the players׳ efforts in producing the public good. In our second model, cooperation consists of the defense of a public, and/or a private good with by-product benefits, and adversity is measured by the number of random attacks (e.g., by a predator) facing the players. In both of these models, our analysis confirms the existence of the so-called boomerang effect, which states that in a harsh environment, the individual player has few incentives to unilaterally defect in a situation of joint cooperation. Focusing on such an effect in isolation leads to the "common-enemy" hypothesis that a larger degree of adversity increases the probability of cooperation. Yet, we also find that a sucker effect may simultaneously exist, which says that in a harsh environment, the individual player has few incentives to unilaterally cooperate in a situation of joint defection. Looked at in isolation, the sucker effect leads to the competing hypothesis that a larger degree of adversity decreases the probability of cooperation. Our analysis predicts circumstances in which the "common enemy" hypothesis prevails, and circumstances in which the competing hypothesis prevails. Copyright © 2016 Elsevier Ltd. All rights reserved.

Complex Odor from Plants under Attack: Herbivore's Enemies React to the Whole, Not Its Parts

Science.gov (United States)

van Wijk, Michiel; de Bruijn, Paulien J. A.; Sabelis, Maurice W.

2011-01-01

Background Insect herbivory induces plant odors that attract herbivores' natural enemies. Assuming this attraction emerges from individual compounds, genetic control over odor emission of crops may provide a rationale for manipulating the distribution of predators used for pest control. However, studies on odor perception in vertebrates and invertebrates suggest that olfactory information processing of mixtures results in odor percepts that are a synthetic whole and not a set of components that could function as recognizable individual attractants. Here, we ask if predators respond to herbivore-induced attractants in odor mixtures or to odor mixture as a whole. Methodology/Principal Findings We studied a system consisting of Lima bean, the herbivorous mite Tetranychus urticae and the predatory mite Phytoseiulus persimilis. We found that four herbivore-induced bean volatiles are not attractive in pure form while a fifth, methyl salicylate (MeSA), is. Several reduced mixtures deficient in one component compared to the full spider-mite induced blend were not attractive despite the presence of MeSA indicating that the predators cannot detect this component in these odor mixtures. A mixture of all five HIPV is most attractive, when offered together with the non-induced odor of Lima bean. Odors that elicit no response in their pure form were essential components of the attractive mixture. Conclusions/Significance We conclude that the predatory mites perceive odors as a synthetic whole and that the hypothesis that predatory mites recognize attractive HIPV in odor mixtures is unsupported.

Prospecting for viral natural enemies of the fire ant Solenopsis invicta in Argentina.

Directory of Open Access Journals (Sweden)

Steven M Valles

Full Text Available Metagenomics and next generation sequencing were employed to discover new virus natural enemies of the fire ant, Solenopsis invicta Buren in its native range (i.e., Formosa, Argentina with the ultimate goal of testing and releasing new viral pathogens into U.S. S. invicta populations to provide natural, sustainable control of this ant. RNA was purified from worker ants from 182 S. invicta colonies, which was pooled into 4 groups according to location. A library was created from each group and sequenced using Illumina Miseq technology. After a series of winnowing methods to remove S. invicta genes, known S. invicta virus genes, and all other non-virus gene sequences, 61,944 unique singletons were identified with virus identity. These were assembled de novo yielding 171 contiguous sequences with significant identity to non-plant virus genes. Fifteen contiguous sequences exhibited very high expression rates and were detected in all four gene libraries. One contig (Contig_29 exhibited the highest expression level overall and across all four gene libraries. Random amplification of cDNA ends analyses expanded this contiguous sequence yielding a complete virus genome, which we have provisionally named Solenopsis invicta virus 5 (SINV-5. SINV-5 is a positive-sense, single-stranded RNA virus with genome characteristics consistent with insect-infecting viruses from the family Dicistroviridae. Moreover, the replicative genome strand of SINV-5 was detected in worker ants indicating that S. invicta serves as host for the virus. Many additional sequences were identified that are likely of viral origin. These sequences await further investigation to determine their origins and relationship with S. invicta. This study expands knowledge of the RNA virome diversity found within S. invicta populations.

Primary amoebic meningoencephalitis caused by Naegleria fowleri: an old enemy presenting new challenges.

Full Text Available First discovered in 1899, Naegleria fowleri is a protist pathogen, known to infect the central nervous system and produce primary amoebic meningoencephalitis. The most distressing aspect is that the fatality rate has remained more than 95%, despite our advances in antimicrobial chemotherapy and supportive care. Although rare worldwide, most cases have been reported in the United States, Australia, and Europe (France. A large number of cases in developing countries go unnoticed. In particular, religious, recreational, and cultural practices such as ritual ablution and/or purifications, Ayurveda, and the use of neti pots for nasal irrigation can contribute to this devastating infection. With increasing water scarcity and public reliance on water storage, here we debate the need for increased awareness of primary amoebic meningoencephalitis and the associated risk factors, particularly in developing countries.

Writing a love letter to your (perceived enemy: Thích Nhất Hạnh and the rhetoric of nonviolence

Directory of Open Access Journals (Sweden)

Michael PHILLIPS-ANDERSON

2017-07-01

Full Text Available Vietnamese Buddhist monk and peace activist Thích Nhất Hạnh has been a leading figure in the promotion of nonviolent practice throughout the world. We examine his concept of engaged Buddhism, theories of nonviolence, and intersections with rhetorical and communication studies. His approach takes nonviolence beyond the realm of refusing to use physical violence to the recognition that language itself can be violent. In order to understand this approach we detail the concepts of interbeing, loving speech, and deep listening. We examine the role of love in Nhất Hạnh’s theory of nonviolence, comparing it with approaches taken by Mahatma Gandhi and Martin Luther King, Jr. Examples are given from many of Nhất Hạnh’s speeches and writings with particular attention paid to a love letter he wrote to US President George W. Bush during the Iraq War. Thích Nhất Hạnh offers the practice of writing a love letter to one’s perceived enemy as a means to persuade for a turn to nonviolence.

Public health workforce employment in US public and private sectors.

Science.gov (United States)

Kennedy, Virginia C

2009-01-01

The purpose of this study was to describe the number and distribution of 26 administrative, professional, and technical public health occupations across the array of US governmental and nongovernmental industries. This study used data from the Occupational Employment Statistics program of the US Bureau of Labor Statistics. For each occupation of interest, the investigator determined the number of persons employed in 2006 in five industries and industry groups: government, nonprofit agencies, education, healthcare, and all other industries. Industry-specific employment profiles varied from one occupation to another. However, about three-fourths of all those engaged in these occupations worked in the private healthcare industry. Relatively few worked in nonprofit or educational settings, and less than 10 percent were employed in government agencies. The industry-specific distribution of public health personnel, particularly the proportion employed in the public sector, merits close monitoring. This study also highlights the need for a better understanding of the work performed by public health occupations in nongovernmental work settings. Finally, the Occupational Employment Statistics program has the potential to serve as an ongoing, national data collection system for public health workforce information. If this potential was realized, future workforce enumerations would not require primary data collection but rather could be accomplished using secondary data.

Changes in public health nursing education have been consideration. Theses changes include a dramatic increase in the number of public health nurses (PHNs) who have enrolled for nursing courses at university. This study was conducted to assess the current status and future of public health nursing education as perceived by teachers and students at three types of schools: universities offering nursing courses, advanced courses for PHNs with junior nursing colleges, and public health nursing schools. Questionnaires were distributed to teachers and students by mail. The questions that were sent to teachers asked which subjects were required to become a certified PHN, which lecture methods were employed to teach public health-particularly community health assessment methods, and what was the level of awareness of the activities of PHNs. Students were asked about their motivation to be a PHN, their understanding of public health, their views of public health activities and their images of PHNs. Responses were analyzed and differences between questionnaires from different schools were noted. These included the number of subjects and the total number of hours spent doing practical training and field experience in universities and the other types of schools, and the number of teachers. Differences also were noted among students at three types of schools about their age, methods of public health activities, knowledge about activities undertaken by PHNs, and their images of PHNs. No differences were observed among the schools with respect to the students' conceptual understanding of public health. Student age, practical training and field experience were found to contribute to their level of understanding of public health and public health nursing. It is thus necessary to consider the teaching methods employed by universities that administer nursing courses and the effectiveness of courses offered by graduate schools.

Examining publication bias—a simulation-based evaluation of statistical tests on publication bias

Directory of Open Access Journals (Sweden)

Andreas Schneck

2017-11-01

Full Text Available Background Publication bias is a form of scientific misconduct. It threatens the validity of research results and the credibility of science. Although several tests on publication bias exist, no in-depth evaluations are available that examine which test performs best for different research settings. Methods Four tests on publication bias, Egger’s test (FAT, p-uniform, the test of excess significance (TES, as well as the caliper test, were evaluated in a Monte Carlo simulation. Two different types of publication bias and its degree (0%, 50%, 100% were simulated. The type of publication bias was defined either as file-drawer, meaning the repeated analysis of new datasets, or p-hacking, meaning the inclusion of covariates in order to obtain a significant result. In addition, the underlying effect (β = 0, 0.5, 1, 1.5, effect heterogeneity, the number of observations in the simulated primary studies (N = 100, 500, and the number of observations for the publication bias tests (K = 100, 1,000 were varied. Results All tests evaluated were able to identify publication bias both in the file-drawer and p-hacking condition. The false positive rates were, with the exception of the 15%- and 20%-caliper test, unbiased. The FAT had the largest statistical power in the file-drawer conditions, whereas under p-hacking the TES was, except under effect heterogeneity, slightly better. The CTs were, however, inferior to the other tests under effect homogeneity and had a decent statistical power only in conditions with 1,000 primary studies. Discussion The FAT is recommended as a test for publication bias in standard meta-analyses with no or only small effect heterogeneity. If two-sided publication bias is suspected as well as under p-hacking the TES is the first alternative to the FAT. The 5%-caliper test is recommended under conditions of effect heterogeneity and a large number of primary studies, which may be found if publication bias is examined in a

The country's competitiveness in the level of nanotechnology activity determine the total number of nanotechnology publications and the mean number of citations. In this paper, we have analyzed the scientific nanotechnology activity of the most active countries in this field (countries whose number of nanotechnology publications exceeds 1,000 annually. We used data on nanotechnology publications collected from Web of Science - WoS database and published by Nano Statistics - Nano Science, Technology and Industry Scoreboard. We analyzed the trend of the total number of published nanotechnology publications, the mean number of citations trend, trend of the relations of published nanotechnology publications and gross domestic product, and the trend of relations of published nanotechnology publications and the number of residents in the surveyed countries. Based on the regression-correlation analysis, we predicted the expected value of the total number of nanotechnology publications published in 2015 for China and the United States, because these are the countries that dominate in the total number of published nanotechnology publications in the world.

There is a dearth of studies examining the relationship between research output and other socio-demographic indicators in the Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates). The three interrelated aims of this study were, first, to ascertain the number of biomedical publications in the GCC from 1970 to 2010; second, to establish the rate of publication according population size during the same period and, third, to gauge the relationship between the number of publications and specific socio-economic parameters. The Medline database was searched in October 2010 by affiliation, year and publication type from 1970 to 2010. Data obtained were normalised to the number of publications per million of the population, gross domestic product, and the number of physicians in each country. The number of articles from the GCC region published over this 40 year period was 25,561. Saudi Arabia had the highest number followed by Kuwait, UAE, and then Oman. Kuwait had the highest profile of publication when normalised to population size, followed by Qatar. Oman is the lowest in this ranking. Overall, the six countries showed a rising trend in publication numbers with Oman having a significant increase from 1990 to 2005. There was a significant relationship between the number of physicians and the number of publications. The research productivity from GGC has experienced complex and fluctuating growth in the past 40 years. Future prospects for increasing research productivity are discussed with particular reference to the situation in Oman.

The life of game birds (pheasants) in nature is coupled with a number of difficulties in all seasons of the year. This refers to finding food, breeding, laying eggs, raising the young, fleeing from their natural enemies and lack of protection from unfavorable climatic conditions. The pheasants that live in captivity – aviaries for pheasants – do not have such difficulties – they are fed regularly by quality feed for pheasants, they are protected from bad weather and natural enemies. ...

Financial appraisal of efficiency investments. Why the good may be the worst enemy of the best

Energy Technology Data Exchange (ETDEWEB)

Verbruggen, A. [University of Antwerp, Prinsstraat 13, 2000 Antwerp (Belgium)

2012-11-15

This methodological paper has a didactic goal: improving our understanding of what 'cost optimal energy performance of buildings' means and how financial appraisal of efficiency investments must be set up. Three items merit improvement. First, focus on the endowment character of energy performance of long-living assets like buildings. Second, defining cost optimal requires more than a comparative static trade-off scheme; cost optimal refers to dynamic efficiency, which results from technology dynamics induced by changes in society and policy. Third, financial appraisal is a more complex issue than simple net present value and life cycle cost calculations. It must reflect the time sequential dynamics of real-life processes including real-life decision making. Financial appraisal is embedded in a complex framework made up by three dimensions: future time, doubt and irrevocability. The latter dimension connects with issues like lock-in and path dependency that are generally overlooked in net present value calculations. This may lead to very erroneous recommendations regarding efficiency investments, in particular regarding the energy performance endowment of buildings. Mostly irrevocability is used as an argument to 'wait and learn' what has, for example, blocked the pace of climate policy. But the opposite 'choose or lose' is the logical outcome when the methodology is fed with evidenced expectations. The latter boosts energy efficiency to its boundaries, saving it from the middle-of-the-river quagmire where incomplete appraisals are dropping it too often (making the good the worst enemy of the best)

Assessing the Effect of China's National Publicity Films from the Perspective of Public Diplomacy

Directory of Open Access Journals (Sweden)

Cao Wei

2015-12-01

Full Text Available This article empirically assessed the effect of China’s national publicity film launched in Times Square in Manhattan, New York. To this end, the author gave a set of general criteria and indicators to measure the effect of national publicity films. Whether the publicity film was effective depends on whether American people’s image perceptions of China were improved after it was launched. Quantitative indicators are: the number of reports in the target country and the predispositions of the reports; the target country people’s participation and their predispositions; and the real behavior of the target country people. The analysis revealed that the 2011 national publicity film did not achieve the anticipated effect. The number of U.S. mainstream media reports was less than expected and their evaluations were quite negative; the participation of American people was low and the extent of the favorability both of the publicity film and China was not high; and the launch of the publicity film did not trigger a travel boom to China. Accordingly, this article suggested that the future implementation of China’s national publicity films focuses on two aspects: first, pay attention to cultural differences and enhance the comprehensibility of the discourse; second, practice what it preaches and strengthen the credibility of the discourse.

Scaling in public transport networks

Directory of Open Access Journals (Sweden)

C. von Ferber

2005-01-01

Full Text Available We analyse the statistical properties of public transport networks. These networks are defined by a set of public transport routes (bus lines and the stations serviced by these. For larger networks these appear to possess a scale-free structure, as it is demonstrated e.g. by the Zipf law distribution of the number of routes servicing a given station or for the distribution of the number of stations which can be visited from a chosen one without changing the means of transport. Moreover, a rather particular feature of the public transport network is that many routes service common subsets of stations. We discuss the possibility of new scaling laws that govern intrinsic properties of such subsets.

2010-01-01

There is a continually increasing amount of medical literature, which makes the challenge of keeping up to date in the field of dermatology increasingly difficult. To test the hypothesis that the total number and the number in various categories of publications in pediatric and adult dermatology have increased over time in a linear fashion. We evaluated all MEDLINE articles from 1 January 1993 to 31 December 2007. We limited the search to 'skin' AND 'diseases' OR 'dermatology' for adults and children. We used regression analysis to determine the effect of the year of publication on the number of publications of each type. MEDLINE reported 17, 925 publications in adult dermatology and 9011 publications in pediatric dermatology during the evaluation period. There was a significant linear increase in the number of publications over the study period in both categories. There was a steady and similar increase over time in both pediatric and adult dermatology in total publications, randomized controlled trials, clinical trials, case reports, and letters to the editor, while there were too few meta-analyses, editorials, and clinical guidelines to make meaningful analyses of trends. The fields of pediatric and adult dermatology have had a significant yearly increase in studies providing a high level of scientific evidence with a much slower rise in the number of articles providing a lower level of evidence.

This study was carried out in order to distinguish the effect of agroforestry system (combination of agriculture and forestry) on pests and natural enemy's population in poplar research station. Wood is one of the first substances that naturally was used for a long period of time. Forage is an important production of natural resources too. Some factors such as proper lands deficit, lack of economy, pest and disease attacks and faced production of these materials with serious challenges. Agroforestry is a method for decrease of the mentioned problems. The stands of poplar had have planted by complete randomized design with 4 treatments (stand distance) of poplar/alfalfa include 3x4, 3x6.7, 3x8, 3x10 m and 2 control treatments, alfalfa and poplar. The results showed that Chaitophorus populeti had the highest density in poplar and 3x10 m treatments. Monosteira unicostata is another insect pest that had most density in 3x10 m treatment. And alfalfa had high density of Chrysoperla carnea. The density of Coccinella septempunctata, were almost equal in all treatments.

Brown, Ted; Gutman, Sharon A; Ho, Yuh-Shan; Fong, Kenneth N K

2018-01-01

Bibliometrics involves the statistical analysis of the publications in a specific discipline or subject area. A bibliometric analysis of the occupational therapy refereed literature is needed. A bibliometric analysis was completed of the occupational therapy literature from 1991-2014, indexed in the Science Citation Index-Expanded or the Social Sciences Citation Index. Publications were searched by title, abstract, keywords, and KeyWords Plus. Total number of article citations, citations per journal, and contributions per country, individual authors, and institution were calculated. 5,315 occupational therapy articles were published in 821 journals. It appears that there is a citation window of an approximate 10-year period between the time of publication and the peak number of citations an article receives. The top three most highly cited articles were published in Developmental Medicine and Child Neurology, JAMA, and Lancet. AJOT, BJOT and AOTJ published the largest number of occupational therapy articles with the United States, Australia, and Canada producing the highest number of publications. McMaster University, the University of Queensland, and the University of Toronto were the institutions that published the largest number of occupational therapy journal articles. The occupational therapy literature is growing and the frequency of article citation is increasing.

Morelli, John N; Bokhari, Danial

2013-03-01

The aim of this study was to determine whether the distribution of publications among academic radiology departments in the United States is Gaussian (ie, the bell curve) or Paretian. The search affiliation feature of the PubMed database was used to search for publications in 3 general radiology journals with high Impact Factors, originating at radiology departments in the United States affiliated with residency training programs. The distribution of the number of publications among departments was examined using χ(2) test statistics to determine whether it followed a Pareto or a Gaussian distribution more closely. A total of 14,219 publications contributed since 1987 by faculty members in 163 departments with residency programs were available for assessment. The data acquired were more consistent with a Pareto (χ(2) = 80.4) than a Gaussian (χ(2) = 659.5) distribution. The mean number of publications for departments was 79.9 ± 146 (range, 0-943). The median number of publications was 16.5. The majority (>50%) of major radiology publications from academic departments with residency programs originated in Pareto rather than a normal distribution.

1984-01-01

Many of the important and creative developments in modern mathematics resulted from attempts to solve questions that originate in number theory. The publication of Emil Grosswald’s classic text presents an illuminating introduction to number theory. Combining the historical developments with the analytical approach, Topics from the Theory of Numbers offers the reader a diverse range of subjects to investigate, including: * divisibility * congruences * the Riemann zeta function * Diophantine equations and Fermat’s conjecture * the theory of partitions Comprehensive in nature, Topics from the Theory of Numbers is an ideal text for advanced undergraduates and graduate students alike. "In my opinion it is excellent. It is carefully written and represents clearly a work of a scholar who loves and understands his subject. One can only wish more authors would take such pains and would be as good and honest expositors as Grosswald." — Marc Kac "This book is designed for use in a first course in number theory at...

Besides thematic andtemporal components this kind of studies include spatial component which is crucialfor the use of GIS methodology and advanced possibilities of geospatial analysis. Duringour studies on jumping plant lice (Psylloidea fauna and their natural enemies on theterritory of Serbia which lasted for several years, a large number of spatially referenceddata related to this group of insects were collected. The process of collecting, archivingand classifying the data on each species was improved by applying the GIS methodologicalapproach after which the data were entered into database. The analysis of datausing thematic and spatial queries, as well as graphic, numeric and textual display of theresults from studies enabled simpler and more complete survey of horizontal and verticaldistribution of jumping plant lice, their biology and relationship with plants, predatorsand parasitoids.

To identify public health open educational resources (OER) available online, map the identified OER to The Public Health Skills and Career Framework (PHSCF), and triangulate these findings with public health practitioners. Systematic online search for public health OER. An online search was undertaken using a pre-defined set of search terms and inclusion/exclusion criteria. Public health OER were then mapped against the UK PHSCF. The findings of the search were discussed with public health specialists to determine whether or not they used these resources. A number of public health OER were identified, located on 42 websites from around the world. Mapping against the UK PHSCF demonstrated a lack of coverage in some areas of public health education. It was noted that many of the OER websites identified were not those generally used in practice, and those sites preferred by public health specialists were not identified by the online search. Public health OER are available from a number of providers, frequently universities and government organizations. However, these reflect a relatively small pool of original OER providers. Tagging of websites does not always identify their public health content. In addition, users of public health OER may not use search engines to identify resources but locate them using other means.

Compatibility of organic farming treatments against Monosteira unicostata with non-target arthropod fauna of almond trees canopy

Field trials had shown that 1-2 applications of kaolin and potassium salts of fatty acids combined with thyme essential oil (PSTEO) reduced the abundance of the lace bug Monosteira unicostata (Mulsant & Rey) (Hemiptera: Tingidae), an important pest of almond trees in the Mediterranean region. These products could be useful for the control of this pest in organic production of almonds, but higher number of applications could be necessary. However, the possible detrimental effects on the almond orchard ecosystem should be evaluated. In the present work, the effects observed on the non-target arthropod fauna of the almond trees canopy in those field assays are shown. First, a comprehensive report of the non-target arthropod fauna of the almond tree is provided. Regarding natural enemies, most of the predatory arthropods captured were spiders belonging to different families like Salticidae, Thomisidae, Philodromidae, Theridiidae, Araneidae or Oxyopidae. Other predatory families that appeared in significant numbers were Chrysopidae, Anthocoridae, Aeolothripidae, Coccinellidae, Phytoseiidae, Erythraeidae or Forficulidae. Among parasitoids, the most abundant families were Eulophidae, Scelionidae and Dryinidae. Kaolin reduced the abundance of natural enemies and other non-target arthropods as well as their diversity and number of species. On the contrary, PSTEO only produced a slight reduction in the number of natural enemies, whereas no effect was found on the diversity and species richness. These effects were observed despite the reduced number of applications, so greater effect is expected if its frequency is increased in order to achieve an efficient control of M. unicostata.

In the words of one hospital manager, "hospital data is currently indigestible and alien to the average user." Drawing upon the experience of an academic hospital that, contrary to established practice, published real numbers alongside rates and ratios during a Clostridium difficile outbreak, the authors examined the pitfalls of publishing only abstract performance measures and the advantages of releasing real numbers to the public. This article identifies lessons for hospital board governance, media relations, employee communications, and citizen and patient engagement that are applicable across the healthcare industry in many countries. If healthcare is to be a caring industry, then care should be taken in the public reporting of data and information.

Fight Swack, Adapt to Climate Change or How to Use Humor to Engage the Public in Climate Issues

Science.gov (United States)

Ellis, R.; Elinich, K.; Johnson, R.; Fink, J.; Crawford, J.

2014-12-01

We are carefully considering how a humor-based campaign can help us communicate important climate change messages. Using pilot campaign strategies, we have engaged local residents in focus groups and interviews to understand how effective the approach can be. Growing educational research suggests learning about climate change can lead to feelings of depression, fear and inaction. Climate change seems too big of a task to take on. But with sweaty back (or "swack" as it's known in some circles), there's a public enemy that can be defeated. As only one piece of an innovative model for informal climate change education, the Climate and Urban Systems Partnership repositions the war on climate change by declaring a war on swack instead. This way, we can talk about climate change in a way it has never been talked about before that will certainly get people's attention. It also answers the common question of, "Yeah, but how does it affect me?" We're educating about responses to climate change because heat waves, floods, and excessive back sweat all kinda suck a lot.

To describe the reporting of public health research in Francophone sub-Saharan Africa (FSA). A bibliometric research study of scientific public health publications in FSA, which includes 24 countries and approximately 260 million people. Two researchers analysed original articles published in 2007 in the medical or social sciences fields and indexed in Scopus. At least one co-author of articles had to be based in FSA. The analysis focused on research field, public health function (WHO classification), FSA country author's affiliation, language, journal type and global burden of disease (WHO classification). Of 1047 articles retrieved by the search, 212 were from the public health field. The number of articles per country varied from 0 to 36. Public health functions examined were health service research (24.5%), health monitoring (27.4%), prevention (15%) and legislation (0.5%). The distribution of health needs described in the articles was close to that of the WHO data for Africa for 2004: infectious and parasitic diseases (70% vs 54%), maternal and perinatal conditions (15% vs 17%), non-communicable diseases (15.6% vs 21%), and injuries (0.5% vs 8%). The areas reported in published articles from sub-Saharan Africa reflect the health needs distribution in Africa; however, the number of publications is low, particularly for prevention. In light of the current focus on evidence-based public health, this study questions whether the international scientific community adequately considers the expertise and perspectives of African researchers and professionals.

The sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is an important pest of vegetables and many other crops worldwide. Eight biorational insecticides (based on oil, plant derivatives, insect growth regulator and fungus) were evaluated in the field for their influence on populations of six natural enemies of B. tabaci. Natural populations of two predators [Chrysoperla carnea Stephen (Neuroptera: Chrysopidae) and Orius spp. (Hemiptera: Anthocoridae)] and two genera of parasitoids [Encarsia spp. and Eretmocerus spp. (Hymenoptera: Aphelinidae)] were evaluated in eggplant (Solanum melongena L.). Also, augmented field populations of three predators [C. carnea, Coccinella undecimpunctata L. (Coleoptera: Coccinellidae) and Macrolophus caliginosus (Wagner) (Hemiptera: Miridae)] were evaluated in cabbage (Brassica oleracea var. capitata L.), cucumber (Cucumis sativus L.) and squash (Cucurbita pepo L.). Regardless of natural enemy or crop, jojoba oil, Biovar and Neemix had the least effect on abundance of the natural enemies in comparison with the other insecticides during a 14 day evaluation period. Conversely, Admiral, KZ oil, Mesrona oil, Mesrona oil + sulfur and natural oil had a high detrimental effect on abundance of the natural enemies. These results demonstrate the differential effects of biorational insecticides for whitefly control on predators and parasitoids in the field.

Foodborne diseases cause 76 million illnesses in the U.S. each year, and almost half of all money spent on food is spent in restaurants. Restaurant inspections are a critical public health intervention for the prevention of foodborne disease. A telephone survey of randomly selected Tennessee residents aged > or =18 was performed. Data were collected on respondents' demographics, knowledge, attitudes, and expectations regarding restaurant inspections. Of 2000 respondents, 97% were aware that restaurants are inspected regularly by the health department. More than half of the respondents believed that inspections should be performed at least 12 times per year; only one third were aware that inspections currently occur only twice per year in Tennessee. More than one third of the respondents considered an inspection score of > or =90 acceptable for a restaurant at which they would eat; the mean score in Tennessee is 82. When presented with a variety of scenarios, an overwhelming number of respondents felt that public health responses to safety violations should be far more draconian than they actually are. Survey answers did not differ consistently based on respondents' race, gender, or history of having worked in a restaurant. This study identified a number of public misconceptions and unrealistically high expectations of the public health restaurant-inspection system. It is important to improve consumers' understanding of inspection scores and the limitations of regulatory inspections, as well as the role of such inspections in disease prevention.

Carline, Jan D; Patterson, Davis G

2003-05-01

To identify characteristics of health professions schools, public schools, and community-based organizations in successful partnerships to increase the number of underrepresented minority students entering health professions. The Robert Wood Johnson Foundation and the W. K. Kellogg Foundation funded the Health Professions Partnership Initiative program developed from Project 3000 by 2000 of the Association of American Medical Colleges. Semi-structured interviews were completed with awardees and representatives of the funding agencies, the national program office, and the national advisory committee between the fall of 2000 and the summer of 2002. Site visits were conducted at ten sites, with representatives of partner institutions, teachers, parents, and children. Characteristics that supported and hindered development of successful partnerships were identified using an iterative qualitative approach. Successful partnerships included professional schools that had a commitment to community service. Successful leaders could work in both cultures of the professional and public schools. Attitudes of respect and listening to the needs of partners were essential. Public school governance supported innovation. Happenstance and convergence of interests played significant roles in partnership development. The most telling statement was "We did it, together." This study identifies characteristics associated with smoothly working partnerships, and barriers to successful program development. Successful partnerships can form the basis on which educational interventions are built. The study is limited by the definition of success used, and its focus on one funded program. The authors were unable to identify outcomes in terms of numbers of children influenced by programs or instances in which lasting changes in health professions schools had occurred.

Quoting an article in well-known textbooks is held as a credit for that paper. The numbers of Iranian publications mentioned in endodontic textbooks have increased during recent years. The aim of this investigation was to evaluate the number of Iranian articles quoted in eminent endodontic textbooks. Three known textbooks (Ingle's Endodontics, Seltzer and Bender's Dental Pulp and Cohen's Pathways of the Pulp) were chosen and all the editions of the textbooks since 2000 were investigated for quoted Iranian publications. Only Iranian authors with affiliations from a domestic university were chosen. All references at the end of each chapter were read by hand searching, and results were noted. The trend and percentage of Iranian publications in different editions of the textbooks were also calculated. The number of citations of these publications in Google Scholar and Scopus databases were also obtained. The number of Iranian publications in all well-known textbooks have notably increased since 2000. The number and percentage of Iranian publications in the latest edition of Cohen's Pathways of the Pulp was higher compared to other textbooks as well as the previous edition of the same text. Number and percentage of Iranian publications in the field of endodontics in all three textbooks have remarkably increased since 2000.

In real situations, the value of public goods will be reduced or even lost because of external factors or for intrinsic reasons. In this work, we investigate the evolution of cooperation by considering the effect of depreciation of public goods in spatial public goods games on a square lattice. It is assumed that each individual gains full advantage if the number of the cooperators nc within a group centered on that individual equals or exceeds the critical mass (CM). Otherwise, there is depreciation of the public goods, which is realized by rescaling the multiplication factor r to (nc/CM)r. It is shown that the emergence of cooperation is remarkably promoted for CM > 1 even at small values of r, and a global cooperative level is achieved at an intermediate value of CM = 4 at a small r. We further study the effect of depreciation of public goods on different topologies of a regular lattice, and find that the system always reaches global cooperation at a moderate value of CM = G - 1 regardless of whether or not there exist overlapping triangle structures on the regular lattice, where G is the group size of the associated regular lattice.

Woods, William J; Tracy, Daniel; Binson, Diane

2003-01-01

Although gay bathhouses have been the subject of debate and some public health policy for decades, the relative number and geographic distribution of these establishments has not been described. As a result, it is easy to miss or ignore them in making public policy in response to discase prevention. No straightforward methodology for such a description is available, so we used a series of gay travel books, first published in 1965 by the Damron Company, to estimate this distribution in the United States and Canada. Each of the annual guides published from 1968 to 1999 were reviewed for listings of bathhouses and sex clubs. The results suggest that bathhouses and other similar establishments exist in most states and provinces and in most large and many moderate-sized cities. Furthermore, the largest numbers of listings for bathhouses were in the same six cities across the decades, three in the U.S. and three in Canada. The greatest change in the number of listings was seen in the three U.S. cities where a public policy of closure was attempted. Nevertheless, the numbers of venues in these three cities have been increasing again since the early 1990s, although nothing near the numbers of listings in the late 1970s and early 1980s.

Celeste, Roger Keller; Warmling, Cristine Maria

2014-06-01

The scope of this paper is to describe characteristics of the scientific output in the area of public oral health in journals on public health and dentistry nationwide. The Scopus database of abstracts and quotations was used and eight journals in public health, as well as ten in dentistry, dating from 1947 to 2011 were selected. A research strategy using key words regarding oral health in public health and key words about public health in dentistry was used to locate articles. The themes selected were based on the frequency of key words. Of the total number of articles, 4.7% (n = 642) were found in oral health journals and 6.8% (n = 245) in public health journals. Among the authors who published most, only 12% published in both fields. There was a percentile growth of public oral health publications in dentistry journals, though not in public health journals. In dentistry, only studies indexed as being on the topic of epidemiology showed an increase. In the area of public health, planning was predominant in all the phases studied. Research to evaluate the impact of research and postgraduate policies in scientific production is required.

Ethics in Online Publications.

Science.gov (United States)

Vervaart, Peter

2014-10-01

Journals have been publishing the results of scientific investigations since the founding of Philosophical Transactions in 1665. Since then we have witnessed a massive expansion in the number of journals to the point that there are now approximately 28,000 active, peer reviewed journals collectively publishing more than 1.8 million articles per year. Before the mid-1990s, these journals were only available on paper but by the end of the 20th century, most journals had moved to online platforms. Online publication has also served as the impetus for the move to 'open-access' to the information contained in journals. The fact that a publication is 'on-line' and 'open-access' does not negate the responsibility of the author and the publisher to publish in an ethical way. [1] The document produced by the IFCC Ethics Task Force (TF-E) on publication ethics states that 'Ethics in Science at its broadest level encompasses research ethics, medical ethics, publication ethics, conflicts of interest, ethical responsibilities as educator, plus many other areas.' Thus publication ethics is a continuum from the first step of research design through to the information being read by the reader. In general terms 'publication ethics' includes the ethical behaviour of the authors in writing and submitting a scientific manuscript to a publisher for the purpose of publication, thus any discussion of publication ethics must include the role of the authors, referees, publisher and reader and the issues of authorship (and the use of 'ghosts'), plagiarism, duplicate publication (including in different languages), image manipulation (particularly in the era of digitisation), and conflict of interest [2]. To aid the authors, and others involved in the process of publication, a number of resources are now available particularly those from the Committee on Publication Ethics (COPE) [3] and the World Association of Medical Editors (WAME) [4]. More recently the issue of 'publisher ethics' has

Enemies of ethics equals environmental exodus, part 1.

Nursing is known as a respected profession in society. Nursing is also ranked as a leading career fostering unethical behavior amongst one another. Historically, nurses are known to "eat their young," meaning new graduate nurses may undergo a brief period of hazing conducted by the experienced nurse. In the past two decades, research demonstrates an increasing trend, often acceptable within an organization, of bullying, lateral violence and mobbing amongst nurses. This type of intentional repetitive harassment inflicts physical and psychological harm to nursing colleagues. It is important for nurses to be familiar with signs of bullying, feel confident in sharing the observation with leadership, and possess the knowledge to make an ethical decision. This type of aggression within an organization affects all employees, the organization's finances and reputation, and most importantly, the quality of patient care, all negatively. The culture of an organization reflects the leadership. Transformational management style, open communication, behavioral expectations, policies and procedures, along with a zero-tolerance course of action for bullying behaviors, are necessary when developing a healthy workplace environment. Laws and regulations in certain states are in place supporting healthy workplace environments. Public awareness concerning bullying, mobbing, and harassment within the workplace has increased secondary to the media's publicity on the subject. Nurses should reflect on the theoretical frameworks of the nursing profession and strive to role model virtues of integrity, ethics and civility within their personal and professional life.

Aim To analyze mistakes and misconduct in multidisciplinary and specialized biomedical journals. Methods We conducted searches through PubMed to retrieve errata, duplicate, and retracted publications (as of January 30, 2014). To analyze publication activity and citation profiles of countries, multidisciplinary, and specialized biomedical journals, we referred to the latest data from the SCImago Journal & Country Rank database. Total number of indexed articles and values of the h-index of the fifty most productive countries and multidisciplinary journals were recorded and linked to the number of duplicate and retracted publications in PubMed. Results Our analysis found 2597 correction items. A striking increase in the number of corrections appeared in 2013, which is mainly due to 871 (85.3%) corrections from PLOS One. The number of duplicate publications was 1086. Articles frequently published in duplicate were reviews (15.6%), original studies (12.6%), and case reports (7.6%), whereas top three retracted articles were original studies (10.1%), randomized trials (8.8%), and reviews (7%). A strong association existed between the total number of publications across countries and duplicate (rs = 0.86, P < 0.001) and retracted items (rs = 0.812, P < 0.001). A similar trend was found between country-based h-index values and duplicate and retracted publications. Conclusion The study suggests that the intensified self-correction in biomedicine is due to the attention of readers and authors, who spot errors in their hub of evidence-based information. Digitization and open access confound the staggering increase in correction notices and retractions. PMID:24577829

Biodiversity research has shown that primary productivity increases with plant species number, especially in many experimental grassland systems. Here, we assessed the correlation between productivity and diversity of phytophages and natural enemy assemblages associated with planting date and intercropping in four cotton agroecosystems. Twenty-one pairs of data were used to determine Pearson correlations between species richness, total number of individuals, diversity indices and productivity for each assemblage every five days from 5 June to 15 September 2012. At the same trophic level, the productivity exhibited a significant positive correlation with species richness of the phytophage or predator assemblage. A significant correlation was found between productivity and total number of individuals in most cotton fields. However, no significant correlations were observed between productivity and diversity indices (including indices of energy flow diversity and numerical diversity) in most cotton fields for either the phytophage or the predator assemblages. Species richness of phytophage assemblage and total individual numbers were significantly correlated with primary productivity. Also, species richness of natural enemy assemblage and total number of individuals correlated with phytophage assemblage productivity. A negative but not significant correlation occurred between the indices of numerical diversity and energy flow diversity and lower trophic-level productivity in the cotton-phytophage and phytophage-predator assemblages for most intercropped cotton agroecosystems. Our results clearly showed that there were no correlations between diversity indices and productivity within the same or lower trophic levels within the phytophage and predator assemblages in cotton agroecosystems, and inter-cropped cotton fields had a stronger ability to support the natural enemy assemblage and potentially to reduce phytophages.

Full Text Available Abstract Background Prospective typing of Salmonella enterica serovar Typhimurium (STM by multiple-locus variable-number tandem-repeat analysis (MLVA can assist in identifying clusters of STM cases that might otherwise have gone unrecognised, as well as sources of sporadic and outbreak cases. This paper describes the dynamics of human STM infection in a prospective study of STM MLVA typing for public health surveillance. Methods During a three-year period between August 2007 and September 2010 all confirmed STM isolates were fingerprinted using MLVA as part of the New South Wales (NSW state public health surveillance program. Results A total of 4,920 STM isolates were typed and a subset of 4,377 human isolates was included in the analysis. The STM spectrum was dominated by a small number of phage types, including DT170 (44.6% of all isolates, DT135 (13.9%, DT9 (10.8%, DT44 (4.5% and DT126 (4.5%. There was a difference in the discriminatory power of MLVA types within endemic phage types: Simpson's index of diversity ranged from 0.109 and 0.113 for DTs 9 and 135 to 0.172 and 0.269 for DTs 170 and 44, respectively. 66 distinct STM clusters were observed ranging in size from 5 to 180 cases and in duration from 4 weeks to 25 weeks. 43 clusters had novel MLVA types and 23 represented recurrences of previously recorded MLVA types. The diversity of the STM population remained relatively constant over time. The gradual increase in the number of STM cases during the study was not related to significant changes in the number of clusters or their size. 667 different MLVA types or patterns were observed. Conclusions Prospective MLVA typing of STM allows the detection of community outbreaks and demonstrates the sustained level of STM diversity that accompanies the increasing incidence of human STM infections. The monitoring of novel and persistent MLVA types offers a new benchmark for STM surveillance. A part of this study was presented at the MEEGID �

The Public Health Innovation Model: Merging Private Sector Processes with Public Health Strengths.

Public health enjoyed a number of successes over the twentieth century. However, public health agencies have arguably been ill equipped to sustain these successes and address the complex threats we face today, including morbidity and mortality associated with persistent chronic diseases and emerging infectious diseases, in the context of flat funding and new and changing health care legislation. Transformational leaders, who are not afraid of taking risks to develop innovative approaches to combat present-day threats, are needed within public health agencies. We propose the Public Health Innovation Model (PHIM) as a tool for public health leaders who wish to integrate innovation into public health practice. This model merges traditional public health program planning models with innovation principles adapted from the private sector, including design thinking, seeking funding from private sector entities, and more strongly emphasizing program outcomes. We also discuss principles that leaders should consider adopting when transitioning to the PHIM, including cross-collaboration, community buy-in, human-centered assessment, autonomy and creativity, rapid experimentation and prototyping, and accountability to outcomes.

Depreciation of public goods in spatial public goods games

International Nuclear Information System (INIS)

Shi, Dong-Mei; Zhuang, Yong; Li, Yu-Jian; Wang, Bing-Hong

2011-01-01

In real situations, the value of public goods will be reduced or even lost because of external factors or for intrinsic reasons. In this work, we investigate the evolution of cooperation by considering the effect of depreciation of public goods in spatial public goods games on a square lattice. It is assumed that each individual gains full advantage if the number of the cooperators n c within a group centered on that individual equals or exceeds the critical mass (CM). Otherwise, there is depreciation of the public goods, which is realized by rescaling the multiplication factor r to (n c /CM)r. It is shown that the emergence of cooperation is remarkably promoted for CM > 1 even at small values of r, and a global cooperative level is achieved at an intermediate value of CM = 4 at a small r. We further study the effect of depreciation of public goods on different topologies of a regular lattice, and find that the system always reaches global cooperation at a moderate value of CM = G − 1 regardless of whether or not there exist overlapping triangle structures on the regular lattice, where G is the group size of the associated regular lattice

Tactic "Tulgama" the Art of War the Mongols XIII century

Leonid A. Bobrov

2015-12-01

Full Text Available In this publication, based on a comprehensive analysis of the sources, considered one of the most important tactics of the Mongols of the XIII century, known under the Turkic name "Tulgama". The name of the maneuver is derived from the Turkic verb "talamak", meaning "to surround, to wrapped up, to turn, to whirl, to twist". It is established that the maneuver "Tulgama" was a special tactic, providing coverage flank (flanks of the enemy in the rear and the application of massed archery shot in his builds. Selected three varieties under consideration tactic: right flank or left flank and steam room (double "Tulgama". The most typical was right flanks "Tulgama" when doing the nomads, covered the left wing of the enemy with its right flank. This allowed the attacking archers to fire from the most convenient position (left-forward, left, and left-back. A characteristic feature of the Mongol tactical art was a steam room (double "Tulgama" when the troops of nomads covered both enemy's flank, concluding the enemy's army in the ring, then attacked her from all four sides. A similar technique could not only shoot down from the position, but almost completely destroy the enemy troops. For the most efficient use of maneuver "Tulgama" the Mongols made increasing use of expanded mesalamines system, with a powerful thrust forward flank groups. The concentration of the shock troops on the flanks (reinforced, including by weakening the Central shelf is dramatically different from the tactics of the Mongols from the traditional tactics of the Turks, whose best part was typically the center of the combat formations. However, direct confrontation of these two approaches during the military campaigns of the XIII century demonstrated the advantages of the Mongol tactical schemes. High efficiency of reception "Tulgama" led to its continued existence in the military art of the nomads.

2010-11-01

Full Text Available In the last years the scientific system of publication was challenged increasingly. Open Access – the free access to scientific information – has contributed a lot to it. Therefore is a profound discussion with the phenomenon Open Access worthwhile. In this context the business model of traditional publishing is compared to that of the Open Access. This comparison should give the impulse to think over the interpretation of the Open Access referring to the Berlin Declaration and to open to new forms of the Open Access. However, for this purpose existing enemy images must be destroyed which were aroused since the last years above all between commercial publishing companies and the science. In this respect the following implementations are not only a dialogue help, but they also refresh the legitimization of commercial publishing companies in the publication process and offer them a new action basis. Because Open Access should be understood not only as a danger – above all it is a challenge and chance for the continuity of commercial scientific publishing companies. The point is that it is possible to break into electronic markets of tomorrow.

This study examines predictors of publication number in career development awardees. We examined whether daily writing predicted publication number among junior faculty. We surveyed 94 career development awardees; the survey consisted of 28 questions in four domains: characteristics, environment, writing practices, and attitudes about writing. Variables that contributed positively to publication number included male gender and those with a negative effect were clinical research and perceiving the need to write as a requirement for advancement. In subgroup analysis of junior faculty, a habit of writing daily was predictive of greater publication numbers. Career development awardees published more first-authored manuscripts if they were male, were involved in nonclinical research, and did not perceive writing as a requirement for advancement. These factors highlight the need to explore the lower overall publication productivity in women and in clinical investigators. Junior faculty members that write daily publish more manuscripts, regardless of gender, research type, or motivators. The benefits of daily writing warrant direct study if not empiric implementation.

The association among residency program and research mentor characteristics, program director perceptions, and the publication of the primary research project for postgraduate year 2 (PGY2) graduates was assessed. Using a validated electronic survey, residency program directors (RPDs) of critical care PGY2 graduates were asked about primary research project publication success, program and research project mentor characteristics, and RPDs' perceptions surrounding project completion. All 55 RPDs surveyed responded; 44 (79%) reported being a research project mentor. PGY2 research project publications in 2011 and 2012 totaled 26 (37%) and 27 (35%), respectively. A significant relationship existed between research project publication and the number of residents in the program ( p project publication is important to their employer ( p projects versus no publications included the number of graduates in the PGY2 program (odds ratio [OR], 5.6; p project publication (OR, 10.2; p project versus no research projects was also independently associated with the RPD's perception that the employer valued research project publication (OR, 5.1; p = 0.04). A survey of RPDs of critical care PGY2 residents found that the number of PGY2 residents, the number of publications by the least experienced research mentor, and the perception that publishing the residents' research projects is important to the employer were independently associated with publication rates of residency research projects.

To test the hypothesis that the number of publications in the field of physical medicine and rehabilitation (PMR) has increased over the last 16 years in a linear fashion, and to compare the trends in publication between the pediatric and adult literature. We evaluated all MEDLINE articles from January 1, 1998, to December 31, 2013, using Medical Subject Headings categories of rehabilitation. An age filter separated adult and pediatric articles. We divided articles into those with a low level of scientific evidence such as letters and editorials, and those with a high level of evidence such as controlled trials and meta-analyses. We used regression analysis to evaluate the effect of the year of publication on the number of publications of each type. Not applicable. Not applicable. Not applicable. Not applicable. MEDLINE reported a total of 98,501 adult publications and 30,895 pediatric publications during the evaluated period. There was a significant linear increase in the total number of publications in adult and pediatric rehabilitation publications with multiplication factors of 3.3 and 2.9, respectively. Importantly, publications with a high level of evidence showed larger multiplication factors compared with those with a low level of evidence (5.5 and 5.1 vs 2.1 and 2.0) for the adult and pediatric literature. The number of publications in the PMR field, especially those with a high level of scientific evidence, has increased linearly over the years, reflecting the rapid evolution of both adult and pediatric PMR.

We previously showed that the number of publications in dermatology is increasing year by year, and positively correlates with improved economic conditions in mainland China, a still developing Asian country. However, the characteristics of publications in dermatology departments in more developed Asian countries such as Japan and South Korea are unknown. In the present study, publications from 2003 through 2012 in dermatology in Japan, South Korea and mainland China were characterized. All data were obtained from http://www.pubmed.com. Dermatology departments in Japan published 4,094 papers, while mainland China and South Korea published 1528 and 1,758 articles, respectively. 48% of articles from dermatology in Japan were original research and 36% were case reports; The number of publications in Japan remained stable over time, but the overall impact factors per paper increased linearly over the last 10 year period (p publications and their impact factors per paper increased markedly. In South Korea, 65% of articles from dermatology were original research and 20% were case reports. The impact factors per paper remained unchanged, despite of the fact that the number of publications increased over the last 10 year period (r2 = 0.6820, p = 0.0032). Only mainland China showed a positive correlation of the number of publications with gross domestic product per capita during this study period. These results suggest that the total number of publications in dermatology correlates with economic conditions only in developing country, but not in more developed countries in Asia. The extent of economic development could determine both the publication quantity and quality.

Public open spaces such as parks and green spaces are key built environment elements within neighbourhoods for encouraging a variety of physical activity behaviours. Over the past decade, there has been a burgeoning number of active living research studies examining the influence of public open space on physical activity. However, the evidence shows mixed associations between different aspects of public open space (e.g., proximity, size, quality) and physical activity. These inconsistencies hinder the development of specific evidence-based guidelines for urban designers and policy-makers for (re)designing public open space to encourage physical activity. This paper aims to move this research agenda forward, by identifying key conceptual and methodological issues that may contribute to inconsistencies in research examining relations between public open space and physical activity.

2006-01-01

Full Text Available A systematic and transparent layout of library material on book shelves of public libraries is one of the essential conditions for successful viewing and searching of materials. The research tried to determine the contemporary classification system of library material for the youth. The data needed for the research was gathered and analyzed by a questionnaire completed by five randomly selected central public libraries. Special collections, arrangement and classification of certain fiction and specialized monographic publications for infants, teenagers and adolescents were analyzed. It was of our interest to observe whether the libraries assign the elements of a call number - which are evident on the library material and in online catalogs – according to standards and current instructions. The article also focuses on the unity and differences of the technical processing, and on color and/or image of labels which additionally explain the classification and the contents of the monographic publications for the youth.

Full Text Available Zika virus (ZIKV disease is caused by a virus transmitted by Aedes mosquito. It presents as flu-like symptoms lasting for 5–7 days and shows potential association with neurological and autoimmune complications such as congenital microcephaly and adult paralysis disorder, Guillain–Barré syndrome. Treatment measures are conservative as the disease is self-limiting. ZIKV earlier affected several tropical regions of Africa and Asia from 1951 to 2006. Subsequently, it moved out from these regions to land as outbreaks in Yap Island, French Polynesia, South America, and most recently in Brazil. The WHO declared it as an international public health emergency in 2016 and an extraordinary event with recommendations for improving communications, tightening vigil on ZIKV infections, and improving mosquito control measures. The authors in this article aim to briefly discuss ZIKV infection, its epidemiology, clinical manifestations, management, and prevention.

Public attitudes to nuclear energy

Energy Technology Data Exchange (ETDEWEB)

van der Pligt, J; Eiser, J R; Spears, R

1984-09-01

The last decade has seen a marked increase in public concern about nuclear energy. As a consequence, it is now recognized that the future of nuclear energy will not only depend on technical and economic factors, but that public acceptability of this technology will play a crucial role in its long-term future. This paper summarizes trends in public reactions to nuclear power in various countries and discusses a number of studies on public beliefs and attitudes to nuclear power in general, and to the building of a nuclear power plant near to one's home. It is concluded that the qualitative aspects of the possible risks of nuclear energy play an important role in the public's perception of this technology. It is also clear, however, that differences in perception of the risks do not embrace all the relevant aspects of the public's assessment of nuclear energy. Public reaction is also related to more-general beliefs and values, such as emphasis on economic versus social priorities, attitudes to technology and environmental concern. 11 references.

Public exposure and number of conspecifics have no influence on ovarian and adrenal activity in the cheetah (Acinonyx jubatus).

Koester, Diana C; Wildt, David E; Brown, Janine L; Meeks, Karen; Crosier, Adrienne E

2017-03-01

Cheetahs in managed zoological collections do not reproduce efficiently, a problem that may be related to environmental/management stressors. In this study, we examined 17 adult female cheetahs to determine the influence of two environmental factors, (1) being housed on- or off-exhibit and (2) number of adult conspecifics (males and/or females) in nearby enclosures, on profiles and concentrations of ovarian and adrenal hormones. Secondarily, we assessed a subset of group-housed siblings (n=5 females in groups of 2 or 3) for effects of long-term cohabitation. All of the females demonstrated waves of estrogen excretion (indicative of ovarian activity) as well as occasional periods of no estrogen production (anestrus). Glucocorticoid and estrogen concentrations were correlated within an individual (r s =0.53; P0.05) on estrogen or glucocorticoid metabolite excretory patterns. Although we recently reported that public exposure can negatively affect sperm production, ovarian steroidogenesis in females was unaffected. There also was no evidence of hyper-adrenal activity. Thus, different methods of ex situ management appear to have minimal influence on ovarian function or stress susceptibility of female cheetahs. Copyright © 2016 Elsevier Inc. All rights reserved.

“Enemy Territory”: Immigration Enforcement in the US-Mexico Borderlands

Directory of Open Access Journals (Sweden)

Walter A. Ewing

2014-08-01

Full Text Available For the last two decades, the guiding strategy of immigration enforcement along the US-Mexico border has been “prevention through deterrence,” or stopping unauthorized immigrants from entering the country rather than apprehending those who have already crossed the border. “Prevention through deterrence” has entailed a massive concentration of enforcement personnel and resources along the border and at ports of entry. It has also led to the detention and removal of increasing numbers of unauthorized immigrants and far greater use of “expedited removal.” As gauged by the doubling in size of the unauthorized immigrant population over the same period, “prevention through deterrence” has not been a successful enforcement strategy. Moreover, it has funneled more migrants to their death in the deserts and mountains of the southwest as they (and smugglers resort to increasingly dangerous routes to evade border enforcement. In addition, there has been public concern over ethnic profiling and the use of extraordinary authority by Border Patrol agents to conduct arbitrary searches within 100 miles of the border. Despite these problems, the federal government continues to spend billions of dollars each year on the “prevention through deterrence” strategy.A first step in overcoming the deficiencies of this border enforcement strategy is to strengthen accountability within the Border Patrol, so that allegations of excessive force and abuse are investigated and adjudicated promptly and appropriately. The culture of the Border Patrol must be transformed to foster respect for rights. More broadly, the mission of the Border Patrol should be to capture dangerous individuals and to disrupt the operations of the transnational criminal organizations that traffic people, drugs, guns, and money. In addition, providing more pathways to legal entry through immigration reform would enhance border security by attenuating the flow of unauthorized

Carpenter, Christopher R.; Cone, David C.; Sarli, Cathy C.

2016-01-01

This article provides a broad overview of widely available measures of academic productivity and impact using publication data and highlights uses of these metrics for various purposes. Metrics based on publication data include measures such as number of publications, number of citations, the journal impact factor score, and the h-index, as well as emerging metrics based on document-level metrics. Publication metrics can be used for a variety of purposes for tenure and promotion, grant applications and renewal reports, benchmarking, recruiting efforts, and administrative purposes for departmental or university performance reports. The authors also highlight practical applications of measuring and reporting academic productivity and impact to emphasize and promote individual investigators, grant applications, or department output.

Harsani, P.; Mulyana, I.; Zakaria, D.

2018-03-01

Goat foraging is one of the games that apply the search techniques within the scope of artificial intelligence. This game involves several actors including players and enemies. The method used in this research is fuzzy logic and Algorithm A*. Fuzzy logic is used to determine enemy behaviour. The A* algorithm is used to search for the shortest path. There are two input variables: the distance between the player and the enemy and the anger level of the goat. The output variable that has been defined is the enemy behaviour. The A* algorithm is used to determine the closest path between the player and the enemy and define the enemy's escape path to avoid the player. There are 4 types of enemies namely farmers, planters, farmers and sellers of plants. Players are goats that aims to find a meal that is a plant. In this game goats aim to spend grass in the garden in the form of a maze while avoiding the enemy. The game provides an application of artificial intelligence and is made in four difficulty levels.

The Effects of Resource Limitation on a Predator-Prey Model with Control Measures as Nonlinear Pulses

Directory of Open Access Journals (Sweden)

Wenjie Qin

2014-01-01

Full Text Available The dynamical behavior of a Holling II predator-prey model with control measures as nonlinear pulses is proposed and analyzed theoretically and numerically to understand how resource limitation affects pest population outbreaks. The threshold conditions for the stability of the pest-free periodic solution are given. Latin hypercube sampling/partial rank correlation coefficients are used to perform sensitivity analysis for the threshold concerning pest extinction to determine the significance of each parameter. Comparing this threshold value with that without resource limitation, our results indicate that it is essential to increase the pesticide’s efficacy against the pest and reduce its effectiveness against the natural enemy, while enhancing the efficiency of the natural enemies. Once the threshold value exceeds a critical level, both pest and its natural enemies populations can oscillate periodically. Further-more, when the pulse period and constant stocking number as a bifurcation parameter, the predator-prey model reveals complex dynamics. In addition, numerical results are presented to illustrate the feasibility of our main results.

Evaluation of three neonicotinoid insecticides against the common pistachio psylla, Agonoscena pistaciae, and its natural enemies.

2014-03-06

The common pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Psyllidae), is a key pest in pistachio orchards in Iran. Chemical control is a common method to manage this pest. Compatibility between natural enemies and pesticides is a primary concern in programs of integrated pest management of the psyllid pest. In this research, susceptibility of fifth instar nymphs of Ag. pistaciae and fourth instar larvae of the two most common predators of this pest, Adalia bipunctata L. (Coleoptera: Coccinellidae) and Coccinella undecimpunctata aegyptiaca Reiche, to acetamiprid, thiamethoxam, and imidacloprid was investigated. Probit analysis of concentration-mortality data was conducted to estimate the LC50 value. The results showed that thiamethoxam with an LC50 value of 56.35 mg a.i./L was more toxic to fifth instar nymphs of Ag. pistaciae in comparison to acetamiprid (60.75 mg a.i/L) and imidacloprid (138.21 mg a.i/L) . Imidacloprid with an LC50 value of 218.89 mg a.i/L compared to acetamiprid (222.65 mg a.i/L) and thiamethoxam (232.37 mg a.i/L) had more lethal effects on fourth instar larvae of Ad. bipunctata. However, on the fourth instar larvae of C. undecimpunctata aegyptica, acetamiprid with an LC50 value of 263.44 mg a.i/L was more toxic than thiamethoxam (296.62 mg a.i/L) and imidacloprid (447.82 mg a.i/L). The laboratory findings showed that the three tested insecticides were more toxic to the common pistachio psylla than to its natural predators. Thiamethoxam was the most toxic against Ag. pistaciae. However, its toxicity to the predators was lower than imidacloprid and acetamiprid. This result suggests that thiamethoxam is the best insecticide for control of Ag. pistaciae in combination with predatory lady beetles. This is an open access paper.

The challenge of corporatisation: the experience of Portuguese public hospitals.

Rego, Guilhermina; Nunes, Rui; Costa, José

2010-08-01

The inability of traditional state organisations to respond to new economic, technological and social challenges and the associated emerging problems has made it necessary to adopt new methods of health management. As a result, new directions have emerged in the reform of Public Administration together with the introduction of innovative models. The aim is to achieve a type of management that focuses on results as well as on effort and efficiency. We intend to analyse to what extent the adoption of business management models by hospital healthcare units can improve their performance, mainly in terms of standards of efficiency. Data envelopment analysis (DEA) was used to investigate the efficiency of a set of public Portuguese hospitals. The aim was to evaluate the impact of business management in Portuguese public hospitals with regards to efficiency, specifically taking into account the fact that lack of resources and increased health care needs are a present and future reality. From a total of 83 public hospitals, a sample of 59 hospitals was chosen, of which 21 are state-owned hospital enterprises (SA) and 38 are traditional public administration sector hospitals (SPA). This study evaluates hospital performance by calculating two efficiency measures associated with two categories of inputs. The first efficiency measures the costs associated with hospital production lines and the number of beds (representing fixed capacity) as inputs. The annual costs generated by the hospitals in the consumption of capital and work (direct and indirect costs) are used. A second measure of efficiency is calculated separately. This measure includes in the inputs the number of beds as well as the human resources available (number of doctors, number of nurses and other personnel) in each hospital. With regard to output, the variables that best reflect the hospital services rendered were considered: number of inpatient days, patients discharged, outpatient visits, emergencies

Background China has been experiencing huge changes in all aspects including dermatologic research since its reform in 1978. However, how the economic and intellectual development has influenced the publication trends in the field of dermatology, which could mirror the scientific development in other medical disciplines, is unknown. In the present study, we analyzed the publication trends from departments of dermatology in mainland China from 2002 to 2011. Materials and Methods All publication data were obtained from www.pubmed.com. Only papers published from dermatology departments of mainland China were used for analysis. Results The number of publications increased 10-fold over this 10 year period. A total 1,231 of articles were published in English in 251 journals between 2002 and 2011. A total of 129 journals published only one paper from dermatology departments of mainland China. Over 60% of articles were original research and 21.7% were case reports. Among these 251 journals, foremost was the Journal of Clinical Experimental Dermatology, which published 5.9% of all papers from mainland China. 2.7% papers were published in the Journal of Investigative Dermatology. The number of publications positively correlated with the changes in gross domestic product per capita during the study period. Conclusions These results suggest that the number of publications in the dermatology field has increased markedly in mainland China over the last 10 years. This dramatic increase in publications could be, at least partially, attributed to the significant improvement in economic conditions in mainland China. PMID:23968296

The number of publications positively correlated with the changes in gross domestic product per capita during the study period. These results suggest that the number of publications in the dermatology field has increased markedly in mainland China over the last 10 years. This dramatic increase in publications could be attributed, at least partially, to the significant improvement in economic conditions in mainland China. © 2013 The International Society of Dermatology.

Tobacco control (TC) research capacity and productivity are critical for developing evidence-informed interventions that will reduce the harmful effects of smoking. The aim of this paper was to investigate New Zealand's (NZ) TC research capacity along with the quantity and quality of publications, following two government initiatives aimed, in part, at improving the quantity and quality of NZ TC research. Scopus was searched for articles with at least one NZ author and where the topic was of primary relevance to TC. Publications were organized into two time periods, following the government initiatives, 1993-2003 and 2004-2009. We analyzed the number of publications, publication journals, type of publications, impact (using the impact factor), and authorship. There has been an increase in number and impact of publications and number of authors. The number of publications has increased from an average of 14 (1994-2003) to 38 per year (2004-2009). The number of journals published increased from 64 to 86. The impact during 2004-2009 was almost threefold than in 1993-2003. The number of authors increased from 212 to 345, and the number of authors who had at least one first-authored publication increased from 80 to 124. These results show an encouraging trend in NZ TC research, with an increase in research productivity, quality, and in research capacity. It is possible that government-initiated and -funded infrastructural support contributed to increasing needed TC research, which supports the worth of such initiatives.

Known or knowing publics? Social media data mining and the question of public agency

Directory of Open Access Journals (Sweden)

Helen Kennedy

2015-10-01

Full Text Available New methods to analyse social media data provide a powerful way to know publics and capture what they say and do. At the same time, access to these methods is uneven, with corporations and governments tending to have best access to relevant data and analytics tools. Critics raise a number of concerns about the implications dominant uses of data mining and analytics may have for the public: they result in less privacy, more surveillance and social discrimination, and they provide new ways of controlling how publics come to be represented and so understood. In this paper, we consider if a different relationship between the public and data mining might be established, one in which publics might be said to have greater agency and reflexivity vis-à-vis data power. Drawing on growing calls for alternative data regimes and practices, we argue that to enable this different relationship, data mining and analytics need to be democratised in three ways: they should be subject to greater public supervision and regulation, available and accessible to all, and used to create not simply known but reflexive, active and knowing publics. We therefore imagine conditions in which data mining is not just used as a way to know publics, but can become a means for publics to know themselves.

Public consultation in public policy information: a state-of-the-art report

Bishop, A.B.; McKee, M.; Hansen, R.D.

1977-01-01

The purpose of the National Waste Terminal Storage (NWTS) Program is to site, construct and operate nuclear waste repositories at several locations. Recent experience indicates that the public is aware of the problems of nuclear waste disposal, and correspondingly there is public concern about how and where to dispose of nuclear wastes. The selection of sites involves a wide range of considerations including geological, technical and environmental feasibility. In addition to these, it is important that societal acceptance of repository options also be taken into account in moving foward with the NWTS Program. Such an incorporation of social considerations and preferences correspondingly implies the need for public consultation in the site selection process. In exploring the concept and state-or-the-art of public involvement in public policy decision, a number of important questions are relevant: (1) What are the basic objectives of public participation in policy formation and program decisions. (2) Who are the ''publics'' that should be involved and how can they be identified. (3) What information should be communicated between the agency and the publics. (4) What techniques are available to elicit public participation and involvement and what are their capabilities. At the outset, it should be noted that the purpose of this paper in addressing these questions is not to design public participation procedures for the NWTS program. Rather, the above are questions that provide a broad framework for developing an understanding of citizen participation in public policy decisions, such as nuclear waste disposal. In this sense, the following discussion is to provide a context and guidance for approaching the problem of organizing and structuring involvement in the NWTS program. Annotated bibliography of 95 references is included

A STUDY OF SYMBOLIC RELATIONS IN PUBLIC TRANSPORT

Directory of Open Access Journals (Sweden)

ANDREI BALAN

2011-04-01

Full Text Available This paper presents an anthropological, exploratory study of the microsocial world of public transport. Our research focuses on the symbolic relations that are being established (verbally or nonverbally between urban transport travellers that do not know each other and the consequences these relations create. Modern urban configuration forces large numbers of individuals to share public space every day. When this space becomes restrictive, symbolic relations and interpersonal behaviors such as territoriality and personal space management become clearer. Due to overcrowding, public transport is the scene of one of the most restrictive public spaces in a city. The challenge was to observe and interpret daily, casual behaviors through a sociological and psychological scheme, following the methodological tradition established by Erving Goffman and the other symbolic interactionists. Finally, our study generates a number of hypotheses and explanatory models for common practices and behaviors in trams and metros regarded from a symbolic perspective.

Do Firms Go Public to Raise Capital?

OpenAIRE

Woojin Kim; Michael Weisbach

2005-01-01

This paper considers the question of whether raising capital is an important reason why firms go public. Using a sample of 16,958 initial public offerings from 38 countries between 1990 and 2003, we consider differences between firms that sell new, primary shares to the public, and existing secondary shares that previously belonged to insiders. Our results suggest that the sale of primary shares is correlated with a number of factors associated with the firm's demand for capital. In particula...

Why feminism in public health?

Science.gov (United States)

Hammarström, A

1999-12-01

The issues raised in this editorial and exemplified within a number of the studies reported in this issue indicate new directions for public health, directions which take feminist scholarship, both outside and within the medical framework, into account. The changing potential of feminist public health, as derived from the articles in this issue, can be summarised within the following issues: new research areas, positioning women as actors, development of theoretical frameworks, reflexive theory of science, interplay between sex and gender, gender-sensitive methods, diversities among women/men, pro-feminist research on men's health and using the results for change. Thus, feminist public health represents a shift towards the new public health, with holistic and multidisciplinary activities, based on theoretical pluralism, multiple perspectives and collective actions with the aim of improving the health of gender-subordinated groups.

The Determinants of the Compliance to Public Procurement Policy Requirements among Public Enterprises in Zimbabwe

Directory of Open Access Journals (Sweden)

Maxwell Sandada

2016-09-01

Full Text Available Many public entities in Zimbabwe are operating in a very volatile environment characterised by public procurement systems open to abuse. Zimbabwe is one of the first countries in Africa to have a Procurement Act however non-compliance issues are still a challenge. Public procurement scandals have been a hot topic with the media and also with the Report of the Auditor General for the financial year ended December 31, 2014 having picked on a lot of issues relating to non-compliance with procurement regulations in a number of public enterprises. The purpose of the study was to assess the influence selected factors (enforcement, professionalism, political interferences, familiarity with Procurement Act regulations and ethics on compliance to procurement regulations within the public entities. A quantitative survey research approach was used to collect data from 144 public procurement professionals in public entities in Harare, Zimbabwe. SPSS software version 21 was used to process the data that were later analysed through correlation and regression analyses. Familiarity with procurement regulations, enforcement and political interference were found to be statistically significant predictors of compliance. The managerial implications and direction for future research are provided.

Sun, in the IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, vol.39, no.1, Jan 1992, pp.8-17In this paper, we propose a joint scheme which combines redundant residue number systems (RRNS) with module isolation (MI) for mitigating single event multiple bit upsets (SEMBUs) in datapath. The proposed hardening scheme employs redundant residues to improve the fault tolerance for datapath and module spacings to guarantee that SEMBUs caused by charge sharing do not propagate among the operation channels of different moduli. The features of RRNS, such as independence, parallel and error correction, are exploited to establish the radiation hardening architecture for the datapath in radiation environments. In the proposed

Å kommunisere en konflikt – aktører i RTs dekning av situasjonen i Ukraina i februar–mars 2014

Malin Østevik

2017-05-01

Full Text Available This article analyses the Russian public diplomacy news organization RT's coverage of the situation in Ukraine in February–March 2014, the period that culminated with the annexation of Crimea. It finds that enemy images were drawn of the West/USA and of Ukrainian radicals, whereas the liberal opposition and in part the new Ukrainian government were subjected to «symbolic annihilation» – that is they were not represented at all, only indirectly in depictions of the enemy image of the other actors. Locating these portrayals in the theoretical literature on «strategic narratives», the author interprets them as attempts at achieving consensus around Russia's own perspectives on international affairs, which include the promotion of a world order in which the USA is no longer a hegemon and Russia is respected as a great power.

Phenology, natural enemies, and efficacy of horticultural oil for control of Chionaspis heterophyllae (Homoptera: Diaspididae) on Christmas tree plantations.

Science.gov (United States)

Fondren, Kirsten M; McCullough, Deborah G

2005-10-01

Pine needle scale, Chionaspis pinifoliae (Fitch), and Chionaspis heterophyllae Cooley are important pests of Scots pine, Pinus sylvestris L., and other conifers in much of North America. On Christmas tree plantations, these insects are typically controlled by spraying broad-spectrum insecticides when the vulnerable immature stages are present. However, effective control of bivoltine populations can be difficult to achieve due to asynchronous hatch and development of the second generation. Our objectives were to 1) determine the phenology of the second generation of C. heterophyllae in Michigan; 2) characterize the natural enemy complex; and 3) assess the effectiveness of horticultural oil for control of C. heterophyllae on P. sylvestris Christmas tree plantations. We monitored scale populations in three counties in lower Michigan for 3 yr. Scale phenology was consistently associated with cumulative degree-days base 10 degrees C (DD(10 degrees C)). Second-generation egg hatch began at approximately 1230-1300 DD(10 degrees C), and continued for approximately 3 wk. The peak of the second instar coincided with 1500-1600 DD(10 degrees C). Common predators included the coccinellids Chilocorus stigma (Say) and Microweisia misella (LeConte). On average, 70% of the C. heterophyllae population in unsprayed fields was killed by predators in 1999. Two endoparasitic wasps, Encarsia bella Gahan and Marietta mexicana Howard (Hymenoptera: Aphelinidae), also were recovered. In 2000 and 2001, we applied a highly refined horticultural spray oil with a backpack mist blower at 1500-1600 DD(10 degrees). Scale mortality on trees treated with oil ranged from 66 to 80% and was similar to control achieved using conventional insecticides in both years.

2012-11-01

Full Text Available With a view to standardizing the contents offered to future Accounting professionals, the Federal Accounting Council (CFC elaborated the National Proposal for Undergraduate Accountancy Program Contents. Thus, the curriculum that Higher Education Institutions (HEI adopt serves as an ally for students’ professional conquests. Stability and favorable job conditions attract many people to the dispute for a public function, with a growing Braz ilian public competitive examination market. According to the National Association for Protection and Support to Public Competitive Examinations (Anpac, between 2003 and 2009, the number of public servants in the executive power with a higher education degree in Brazil increased by 26%. The aim of this study was to confront the CFC’s suggested knowledge with the contents required during tests applied in public competitive examinations for Accountancy professionals. The intent is to identify what Public Accounting knowledge is demanded from candidates for the public career. Through a documentary research, 561 calls from public competitive examinations exclusively for Accountancy professionals were selected for the study sample. They were classified according to the proposed program contents, the test questions by the Center for Selection and Event Promotion (Cespe, between 2000 and 2009. In conclusion, the most frequent required Public Accounting areas are contents related to Public Equity and Budget. The results demonstrate that the CFC’s suggested content is in line with the knowledge required from candidates for public functions.

Improving the quality and impact of public health social media activity in Scotland during 2016: #ScotPublicHealth.

Science.gov (United States)

Mackenzie, Douglas Graham

2017-06-07

Social media, including Twitter, potentially provides a route to communicate public health messages to a large audience. Simple measures can boost onward broadcast to other users ('retweeting'). This study compares the impact of a structured programme of social media activity in Scotland during 2016 (using #ScotPublicHealth hashtag) with previous years. The Twitter search function was used to identify tweets between 2014 and 2016 inclusive. The first three tweets from each Twitter user were selected for each period. The number of retweets was used as a measure of impact. The quality of tweets was assessed by recording use of image, weblink (uniform resource locator or URL), mention of another Twitter user and/or hashtag, each of which have been shown to boost number of retweets. The percentage of tweets with an image, URL and/or mention of another Twitter user increased during the period of study. The percentage of tweets retweeted during Scottish Public Health conferences increased from 43% in 2014 to 70% in 2016. The volume of tweeting also increased. The quality and impact of tweets sent by the Scottish Public Health community was higher during 2016 than previous years. Conference tweeting remains an area for improvement. © The Author 2017.

Zhang, Wei; Qian, Chao-Nan; Zeng, Yi-Xin

2014-04-01

Once considered a taboo topic or stigma, cancer is the number one public health enemy in the world. Once a product of an almost untouchable industry, tobacco is indisputably recognized as a major cause of cancer and a target for anticancer efforts. With the emergence of new economic powers in the world, especially in highly populated countries such as China, air pollution has rapidly emerged as a smoking gun for cancer and has become a hot topic for public health debate because of the complex political, economic, scientific, and technologic issues surrounding the air pollution problem. This editorial and the referred articles published in this special issue of the Chinese Journal of Cancer discuss these fundamental questions. Does air pollution cause a wide spectrum of cancers? Should air pollution be considered a necessary evil accompanying economic transformation in developing countries? Is an explosion of cancer incidence coming to China and how soon will it arrive? What must be done to prevent this possible human catastrophe? Finally, the approaches for air pollution control are also discussed.

Cardiovascular Research Publications from Latin America between 1999 and 2008. A Bibliometric Study

2015-01-01

Full Text Available Background: Cardiovascular research publications seem to be increasing in Latin America overall. Objective: To analyze trends in cardiovascular publications and their citations from countries in Latin America between 1999 and 2008, and to compare them with those from the rest of the countries. Methods: We retrieved references of cardiovascular publications between 1999 and 2008 and their five-year post-publication citations from the Web of Knowledge database. For countries in Latin America, we calculated the total number of publications and their citation indices (total citations divided by number of publications by year. We analyzed trends on publications and citation indices over time using Poisson regression models. The analysis was repeated for Latin America as a region, and compared with that for the rest of the countries grouped according to economic development. Results: Brazil (n = 6,132 had the highest number of publications in1999-2008, followed by Argentina (n = 1,686, Mexico (n = 1,368 and Chile (n = 874. Most countries showed an increase in publications over time, leaded by Guatemala (36.5% annually [95%CI: 16.7%-59.7%], Colombia (22.1% [16.3%-28.2%], Costa Rica (18.1% [8.1%-28.9%] and Brazil (17.9% [16.9%-19.1%]. However, trends on citation indices varied widely (from -33.8% to 28.4%. From 1999 to 2008, cardiovascular publications of Latin America increased by 12.9% (12.1%-13.5% annually. However, the citation indices of Latin America increased 1.5% (1.3%-1.7% annually, a lower increase than those of all other country groups analyzed. Conclusions: Although the number of cardiovascular publications of Latin America increased from 1999 to 2008, trends on citation indices suggest they may have had a relatively low impact on the research field, stressing the importance of considering quality and dissemination on local research policies.
