This paper explores shifts in public and private delivery over time through an analysis of Ontario's approach to LTC funding and regulation in relation to other jurisdictions in Canada and abroad. The case of Ontario's long-term care (LTC) policy evolution - from the 1940s until early 2013 -- shows how moving from compliance to deterrence oriented regulation can support consolidation of commercial providers' ownership and increase the likelihood of non-profit and public providers outsourcing their management.

Do abuse deterrent opioid formulations work?

Dart, Richard C; Iwanicki, Janetta L; Dasgupta, Nabarun; Cicero, Theodore J; Schnoll, Sidney H

We performed a systematic review to answer the question, "Does the introduction of an opioid analgesic with abuse deterrent properties result in reduced overall abuse of the drug in the community?" We included opioid analgesics with abuse deterrent properties (hydrocodone, morphine, oxycodone) with results restricted to the metasearch term "delayed onset," English language, use in humans, and publication years 2009-2016. All articles that contained data evaluating misuse, abuse, overdose, addiction, and death were included. The results were categorized using the Bradford-Hill criteria. We included 44 reports: hydrocodone (n = 7), morphine (n = 5), or oxycodone (n = 32) with Food and Drug Administration-approved Categories 1, 2, or 3 abuse deterrent labeling. The data currently available support the Hill criteria of strength (effect size), consistency (reproducibility), temporality, plausibility, and coherence. There was insufficient or no information available for the criteria of biological gradient, experiment, and analogy. We also assessed confounding factors and bias, which indicated that both were present and substantial in magnitude. Our analysis found that only oxycodone extended release (ER) had information available to evaluate abuse deterrence in the community. In Australia, Canada, and the United States, reformulation of oxycodone ER was followed by marked reduction in measures of abuse. The precise extent of reduced abuse cannot be calculated because of heterogeneous data sets, but the reported reductions ranged from 10 to 90 percent depending on the measure and the duration of follow-up.

In defiance of nuclear deterrence: anti-nuclear New Zealand after two decades.

PubMed

Reitzig, Andreas

2006-01-01

In 1984, nuclear-armed and nuclear-powered vessels were banned from New Zealand to express the country's rejection of the nuclear deterrence concept. This led to a disagreement with the United States. Today, the ban on nuclear-powered ships is the only element of the nuclear-free legislation that still strains US-New Zealand relations. This article presents the reasons for the ban on nuclear-powered ships, which include scientific safety concerns, a symbolic rejection of the nuclear deterrence posture, and patriotic factors such as a nuclear-free national identity. The military and economic consequences of the ban are also examined. Since the ban on nuclear-powered vessels appears to be neither widely known abroad nor commonly recognised as a supportive disarmament measure outside New Zealand, it is concluded that whatever the future of this ban will be, New Zealand's anti-nuclear image will remain known internationally through the ban on nuclear arms.

The primary focus of this paper is the impact of key South African leaders on the successful developments and subsequent rollbacks of South Africa`s nuclear weapons capability. It highlights the key milestones in the development of South Africa`s nuclear weapon capability. It also relates how different groups within South Africa (scientists, politicians, military and technocrats) interacted to successfully produce South Africa`s nuclear deterrent. It emphasizes the pivotal influence of the senior political leadership to pursue nuclear rollback given the disadvantages of its nuclear means to achieve vital national interests. The conclusions drawn from flu`s effort are the South African nuclearmore » program was an extreme response to its own identity Crisis. Nuclear weapons became a means to achieving a long term end of a closer affiliation with the West. A South Africa yearning to be identified as a Western nation and receive guarantees of its security rationalized the need for a nuclear deterrent. The deterrent was intended to draw in Western support to counter a feared total onslaught by Communist forces in the region. Two decades later, that same South Africa relinquished its nuclear deterrent and reformed its domestic policies to secure improved economic and political integration with the West.« less

Affect intensity and processing fluency of deterrents.

PubMed

Holman, Andrei

2013-01-01

The theory of emotional intensity (Brehm, 1999) suggests that the intensity of affective states depends on the magnitude of their current deterrents. Our study investigated the role that fluency--the subjective experience of ease of information processing--plays in the emotional intensity modulations as reactions to deterrents. Following an induction phase of good mood, we manipulated both the magnitude of deterrents (using sets of photographs with pre-tested potential to instigate an emotion incompatible with the pre-existent affective state--pity) and their processing fluency (normal vs. enhanced through subliminal priming). Current affective state and perception of deterrents were then measured. In the normal processing conditions, the results revealed the cubic effect predicted by the emotional intensity theory, with the initial affective state being replaced by the one appropriate to the deterrent only in participants exposed to the high magnitude deterrence. In the enhanced fluency conditions the emotional intensity pattern was drastically altered; also, the replacement of the initial affective state occurred at a lower level of deterrence magnitude (moderate instead of high), suggesting the strengthening of deterrence emotional impact by enhanced fluency.

Blood donors' perceptions, motivators and deterrents in Sub-Saharan Africa - a scoping review of evidence.

PubMed

2017-06-01

Achieving an adequate blood supply in Sub-Saharan Africa (SSA) through donor mobilization and retention is crucial. Factors that motivate or deter blood donors vary according to beliefs and social norms. Understanding the factors that influence blood donation behaviour in SSA is vital to developing effective strategies to address blood donor motivation and retention. This review of 35 studies from 16 SSA countries collates available evidence concerning the perceptions, motivators and deterrents that influence blood donors in SSA. The review revealed a common understanding that blood and blood donation save lives. The main deterrent to blood donation was fear due to lack of knowledge and discouraging spiritual, religious and cultural perceptions of blood donation. The main motivators for blood donation were altruism, donating blood for family and incentives. The findings support the need for targeted, culturally sensitive education, recruitment and retention strategies to improve the blood supply in SSA. © 2017 John Wiley & Sons Ltd.

Abuse-deterrent opioid analgesic formulations can help reduce the risk of opioid diversion and abuse. Not all opioid analgesics are available as both extended- and immediate-release dosage forms in abuse-deterrent formulations. Clinicians may have to balance the clinical benefit of a product that does not use abuse-deterrent technology versus the regulatory benefit of using a product with this technology. There is the possibility that a health care professional may be held legally liable when a product without abuse-deterrent qualities is used and a person suffers harm that would not have occurred had an abuse-deterrent formulation been provided. This article reviews legal precedents that inform an understanding of the need to reduce malpractice exposure by identifying patients who are at high risk of opioid diversion and/or abuse and considering the use of an abuse-deterrent formulation for these patients.

Nuclear deterrence in the Arab-Israeli conflict. A case study in Egyptian-Israeli relations

1986-01-01

In order to achieve security and stability, and maximize the chances for resolving the Arab-Israeli conflict, should Egypt and Israel adopt declared nuclear deterrence doctrines. Or would such a move be ineffective, dangerous, or even disastrous. The nuclearization of the Middle East is not necessary: military threats to the survival of the states in the region do not justify the introduction of nuclear weapons. Nuclearization is not desirable: deterrence theory's assumptions and implications exhibit intellectual weakness and its explanatory power is unsatisfactory; nuclear deterrence may reduce the frequency of war, but it pays little attention to the consequences of war;more » and in comparison to defense, nuclear deterrence may lack credibility. Presently, Israel has nuclear capability and delivery systems sufficient to provide security to its vital areas through deterrence of or defense against Arab attacks. The Arabs do not, however, believe that such security extends to the Arab territories occupied by Israel during the June 1967 war. To supply security, nuclear deterrence must be effective, stable, and credible. In a multinuclear environment, the Egyptians and Israelis are likely to meet the requirement for an effective deterrence: the possession of a nuclear capability sufficient to inflict an enormous amount of death and destruction. If the Arabs and Israelis sought and adopted strategies of deterrence, they might be able to meet the requirement for a stable deterrence: the acquisition of second strike capabilities.« less

Oviposition Deterrent Activities of Pachyrhizus erosus Seed Extract and Other Natural Products on Plutella xylostella (Lepidoptera: Plutellidae)

Abstract An extract of a rotenone-containing plant yam bean, Pachyrhizus erosus (L.) Urban, seeds was tested against the diamondback moth, Plutella xylostella (L.) in a greenhouse to determine its potential as an oviposition deterrent and compared with coumarin and rutin, known as diamondback moth oviposition deterrent compounds, rotenone, and an extract of Peruvian cube root, at a concentration of 0.5% (w/v). Oviposition deterrent index (ODI) was used to determine effects of extracts or compounds in inhibiting oviposition of diamondback moth. Coumarin showed a stronger deterrent effect than the yam bean seed extract with a higher ODI value. On the contrary, rotenone, rutin, and the cube root extract, containing 6.7% (w/w) of rotenone, showed no significant deterrent effects having low or negative ODI values, suggesting that the deterrent effect of the yam bean seed extract is not due to rotenone content of the yam bean seeds. The extract of yam bean seed and coumarin partially deterred the moth from laying eggs on treated leaves in a concentration-dependent manner. The effective concentration for 50% deterrency of coumarin and the yam bean seed extract were 0.11 and 0.83% (w/v), respectively. However, the yam bean seed extract showed a residual deterrent effect on the moth even at 3 d after the treatment and is probably because of its low volatile nature. A long-term deterrency of the yam bean seed extract is an advantage over coumarins. Both the yam bean seed extract and coumarin deterred diamondback moth from laying eggs in total darkness, indicating their nonvisual deterrent effect. This made the extract an effective deterrence to diamondback moth in light and in darkness. To conclude, this study revealed the potential of the crude extract of the yam bean seed to prevent diamondback moth from ovipositing on its plant host. PMID:25525107

The transition to a deterrence posture more reliant on strategic defenses

NASA Astrophysics Data System (ADS)

Chrzanowski, Paul L.

1988-12-01

Strategic nuclear deterrence is currently based on the overwhelming capability of the arsenals of the two superpowers. Massive damage would be inflicted upon the military forces and industrial capacity of both sides should nuclear war occur and escalation of conflict not be controlled. Nuclear deterrence has fostered a condition of peace in central Europe and an absence of direct conflict between the U.S. and the Soviet Union. However, some question whether deterrence will remain effective into the indefinite future, and should deterrence fail the consequences are grave.

Objective To assess the feeding deterrent, growth inhibitory and egg hatchability effects of PONNEEM on Helicoverpa armigera (H. armigera). Methods Five oil formulations were prepared at different ratios to assess the feeding deterrent, growth inhibitory and egg hatchability effects on H. armigera. Results Invariably all the newly formulated phytopesticidal oil formulations showed the feeding deterrent and growth inhibitory activities against H. armigera. The maximum feeding deterrent activity of 88.44% was observed at 15 µL/L concentration of PONNEEM followed by formulation A (74.54%). PONNEEM was found to be effective in growth inhibitory activities and egg hatchability at 10 µL/L concentration. It exhibited statistically significant feeding deterrent activity and growth inhibitory activity compared with all the other treatments. Conclusions PONNEEM was found to be effective phytopesticidal formulation to control the larval stage of H. armigera. This is the first report for the feeding deterrent activity of PONNEEM against H. armigera. This newly formulated phytopesticide was patented in India. PMID:25183105

Mosquitoes are well known as vectors of several disease causing pathogens. The extensive use of synthetic insecticides in the mosquito control strategies resulted to the development of pesticide resistance and fostered environmental deterioration. Hence in recent years plants become alternative source of mosquito control agents. The present study assessed the larvicidal and oviposition altering activity of six different plants species-Alstonia scholaris, Callistemon viminalis, Hyptis suaveolens, Malvastrum coromandelianum, Prosopis juliflora, Vernonia cinerea against Aedes albopictus mosquito in laboratory. Leaf extracts of all the six plants species in five different solvents of various polarities were used in the range of 20-400ppm for larval bioassay and 50,100 and 200ppm for cage bioassay (for the study of oviposition behavior) against Ae. albopictus. The larval mortality data were recorded after 24 h and subjected to Probit analysis to determine the lethal concentrations (LC50), while OAI (Oviposition activity index) was calculated for oviposition altering activity of the plant extracts. Vernonia cinerea extract in acetone and C. viminalis extract in isopropanol were highly effective against Aedes albopictus larvae with LC50 value 64.57, 71.34ppm respectively. Acetone extract of P. juliflora found to be strong oviposition-deterrent which inhibited >2 fold egg laying (OAI-0.466) at 100ppm. Vernonia cinerea and C. viminallis leaf extracts have the potential to be used as larvicide and P. juliflora as an oviposition-deterrent for the control of Ae. albopictus mosquito.

Behavioural responses of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), a generalist, cell sap-feeding insect species with piercing-sucking mouthparts, after continuous exposure to two deterrent secondary plant compounds are investigated. We compared in choice assays on bean leaf discs, the settling, feeding, and oviposition preferences of F. occidentalis females that had no experience with the two fatty acid derivatives methyl jasmonate and cis-jasmone before testing (naïve thrips) vs. females that had been exposed to the deterrent compounds before testing (experienced thrips). The thrips were exposed to the deterrents at low or high concentrations for varied time periods and subsequently tested on bean leaf discs treated with the respective deterrent at either a low or a high concentration. Frankliniella occidentalis females avoided settling on the deterrent-treated bean leaf discs for an observation period of 6 h, independent of their previous experience. Our results demonstrate that feeding and oviposition deterrence of the jasmonates to the thrips were not altered by continuous exposure of the thrips to the jasmonates. Habituation was not induced, neither by exposure to the low concentration of the deterrents nor by exposure to the high concentration. These results indicate that the risk of habituation to two volatile deterrent compounds after repeated exposure is not evident in F. occidentalis. This makes the two compounds potential candidates to be integrated in pest management strategies. PMID:26726263

Feeding and oviposition deterrence of three secondary plant compounds and their 1:1 blends to adult female Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) and the potential for habituation of the thrips to the pure compounds and the 1:1 blends at various concentrations were investigated. In choice assays, we tested dose-dependent feeding and oviposition deterrence of the two fatty acid derivatives methyl jasmonate and cis -jasmone, the phenylpropanoid allylanisole, and their blends when directly applied to bean leaf discs. The concentration required to reduce the feeding damage by 50% relative to the control treatment (FDC 50 ) was lowest for cis -jasmone and highest for allylanisole. The feeding deterrent effect of both jasmonates was increased when blended with allylanisole. Feeding deterrence and oviposition deterrence were strongly correlated. In no-choice assays conducted over four consecutive days, we discovered that dilutions at low concentrations (FDC 15 ) applied to bean leaves resulted in habituation to the deterrents, whereas no habituation occurred at higher concentrations (FDC 50 ). We observed a tendency that the 1:1 blends reduce the probability that thrips habituate to the deterrent compounds. Our results may be useful in the development of integrated crop protection strategies with the implementation of allelochemicals as pest behaviour-modifying agents.

The increased use of opioid pain medication has been mirrored by the increased misuse and abuse of these drugs. As part of a multidisciplinary approach to this epidemic, pharmaceutical companies, with the encouragement of the Food and Drug Administration, have increased the development of abuse-deterrent formulations. While all have the goal of treating pain while mitigating misuse and abuse, there are different technologies utilized to impart the abuse-deterrent properties. The goal of this paper is to review the basis of abuse-deterrent formulations, the different types and approaches of some of the abuse-deterrent products, and their current regulatory status in the USA.

The author concludes that there is no easy solution to the problem of nuclear deterrence because there is no way to bridge the extremes of war-winning counterforce and possession without use. The Bishops' central problem was deterrence of attack on US allies or neutrals, but he finds merit in their positions that deterrence need not rely on nuclear threatsmore » and that new ways of thinking are needed for the long run. 20 references.

Strategic forum. Number 70. Regional deterrence strategies for new proliferation threats

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

1996-04-01

The deterrence of armed aggression against the United States, its vital national interests, or its allies has moved beyond the requirements of conventional force deterrence. The proliferation of nuclear, biological, and chemical (NBC) weapons requires a new strategy to ensure effective deterrence against their use by regional states that could not win in a conventional conflict with the United States. Because proliferation has expanded to a number of regional actors, a single strategy is unlikely to be sufficient in deterring states with varied motivations, and social, economic, religious, cultural, and political backgrounds. The Unified Commands-principally the Pacific, Central and Europeanmore » Commands- provide a ready-made framework in which general U.S. deterrence strategies can be tailored to each proliferant state While the Unified Commands would shape the individual deterrence strategies, the national command authority (NCA) would retain control of key decisions. Guidelines for NBC regional deterrence should include developing credible counterproliferation postures, profiling potential adversaries, tailoring our military capabilities to specific threats, integrating NBC preparedness into exercises and warplans, and actively pursuing coalitions designed to deter regional proliferators from threatening to use or using NBC weapons.« less

Background: Mosquitoes are well known as vectors of several disease causing pathogens. The extensive use of synthetic insecticides in the mosquito control strategies resulted to the development of pesticide resistance and fostered environmental deterioration. Hence in recent years plants become alternative source of mosquito control agents. The present study assessed the larvicidal and oviposition altering activity of six different plants species-Alstonia scholaris, Callistemon viminalis, Hyptis suaveolens, Malvastrum coromandelianum, Prosopis juliflora, Vernonia cinerea against Aedes albopictus mosquito in laboratory. Methods: Leaf extracts of all the six plants species in five different solvents of various polarities were used in the range of 20–400ppm for larval bioassay and 50,100 and 200ppm for cage bioassay (for the study of oviposition behavior) against Ae. albopictus. The larval mortality data were recorded after 24 h and subjected to Probit analysis to determine the lethal concentrations (LC50), while OAI (Oviposition activity index) was calculated for oviposition altering activity of the plant extracts. Results: Vernonia cinerea extract in acetone and C. viminalis extract in isopropanol were highly effective against Aedes albopictus larvae with LC50 value 64.57, 71.34ppm respectively. Acetone extract of P. juliflora found to be strong oviposition-deterrent which inhibited >2 fold egg laying (OAI-0.466) at 100ppm. Conclusion: Vernonia cinerea and C. viminallis leaf extracts have the potential to be used as larvicide and P. juliflora as an oviposition-deterrent for the control of Ae. albopictus mosquito.

Consumer-survivors (C/Ss) identify peer support as a resource that facilitates their recovery. However, little is known about the factors that influence or how the peer support relationship (PSR) develops/deteriorates. The purpose of the study was to explore and describe the PSR within the subculture of mental health. Using an ethnonursing method, the study focused on informants from two C/S organizations who received peer support (n = 14). Findings revealed that the PSRs may develop or deteriorate through three, overlapping phases. Contextual factors that influenced the development/deterioration of the PSR are discussed. Understanding the processes and factors that contribute to the development/deterioration of PSRs will enable clinicians and C/Ss to assess and promote the development of healthy, supportive PSRs in mental health.

Deterrent Concentration Measurement with FTIR and Subsequent Ballistic Performance in Medium Caliber Propellant

NASA Technical Reports Server (NTRS)

Furrow, Keith W.; Ritchie, Steve J.; Morris, Amy

2000-01-01

To meet ballistic requirements, medium and small caliber propellants use deterrent coatings to obtain burn rate progressivity. The required amount and distribution of deterrent varies between gun systems, propellant types, and often between lots. Micro Fourier Transform Infrared (FTIR) spectroscopy was used to measure deterrent gradients in RP36 propellants coated with methyl centralite (MC) at different deterrent levels and different processing conditions. The aromatic C-C bonds at 1496 cm(exp -1) wavenumber were used to monitor the deterrent profiles through the grain. Deterrent gradients measured with FTIR spectroscopy were then used to estimate burn rate gradients in the deterred grains. Burn rates were calculated from literature models and from closed bomb data of RP36 containing uniform deterrent concentration. Finally, the burn rate gradients were input into an IBHFG2 model of a 200 cc-closed bomb. The early flame spreading portion of the closed bomb ballistic cycle (0 to 0.2 P/Pmax) was roughly modeled by dividing the charge up into five propellant decks and igniting them at different times in the ballistic cycle. Pressure traces and vivacity curves from closed bomb shots were compared to predictions. In addition to the burn rate gradient, the closed bomb pressure trace was heavily dependent on ignition and flame spread. These two phenomena were not readily distinguishable from one another in deterred grains. The same RP-36 propellant was shot in a 25 mm M793TP round which was again modeled with IBHVG2. Peak pressure and muzzle velocity were accurately modeled when erosive burning effects were empirically factored into the model.

Opioids are essential to the management of pain in many patients, but they also are associated with potential risks for abuse, overdose, and diversion. A number of efforts have been devoted to the development of abuse-deterrent formulations of opioids to reduce these risks. This article summarizes a consensus meeting that was organized to propose recommendations for the types of clinical studies that can be used to assess the abuse deterrence of different opioid formulations. Due to the many types of individuals who may be exposed to opioids, an opioid formulation will need to be studied in several populations using various study designs in order to determine its abuse-deterrent capabilities. It is recommended that the research conducted to evaluate abuse deterrence should include studies assessing: (1) abuse liability; (2) the likelihood that opioid abusers will find methods to circumvent the deterrent properties of the formulation; (3) measures of misuse and abuse in randomized clinical trials involving pain patients with both low risk and high risk of abuse; and (4) post-marketing epidemiological studies.

Asaoka, K

2000-11-01

Sawa-J, CSJ02 and N601 x C601 are selected mutant strains of Bombyx mori, which grow on various artificial diets or temporarily ingest various plant leaves. To examine the mechanisms mediating diet breadth of caterpillars, gustatory spike responses of the silkworms, called 'polyphagous" strains, were compared with normal strains, N137 x C146 and C02. There were notable differences in their feeding habits and in their sensitivity to salicin in deterrent cells in the maxillary medial styloconic sensilla and the epipharyngeal sensilla. By contrast, the deterrent cells of all strains responded similarly to strychnine nitrate in a dose-dependent manner. In additional comparisons of Sawa-J and N137 x C146, Sawa-J maxillary deterrent cells were significantly less sensitive to phloridzin, amygdalin and arbutin, but responded to some alkaloids and 20-hydroxyecdysone with similar or even higher firing rate. These results suggest that the deficiency of the sensitivity to some deterrent compounds on the deterrent cell of the polyphagous strains may be caused by mutant genes and affects the diet breadth of caterpillars.

The value of vengeance and the demand for deterrence.

Crockett, Molly J; Özdemir, Yagiz; Fehr, Ernst

Humans will incur costs to punish others who violate social norms. Theories of justice highlight 2 motives for punishment: a forward-looking deterrence of future norm violations and a backward-looking retributive desire to harm. Previous studies of costly punishment have not isolated how much people are willing to pay for retribution alone, because typically punishment both inflicts damage (satisfying the retributive motive) and communicates a norm violation (satisfying the deterrence motive). Here, we isolated retributive motives by examining how much people will invest in punishment when the punished individual will never learn about the punishment. Such "hidden" punishment cannot deter future norm violations but was nevertheless frequently used by both 2nd-party victims and 3rd-party observers of norm violations, indicating that retributive motives drive punishment decisions independently from deterrence goals. While self-reports of deterrence motives correlated with deterrence-related punishment behavior, self-reports of retributive motives did not correlate with retributive punishment behavior. Our findings reveal a preference for pure retribution that can lead to punishment without any social benefits. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Drug dealers, retaliation, and deterrence.

PubMed

Jacques, Scott; Wright, Richard; Allen, Andrea

2014-07-01

Illicit drug sellers have limited access to formal mediation and therefore are rational targets to predators. As such, dealers are especially reliant on retaliation to deter victimization. Prior scholarship on dealers, retaliation, and deterrence has focused largely on general deterrence, or the effect of punishing one person on others. Research is yet to shed much light on other types of deterrence that dealers engage in. This paper addresses that gap by drawing on qualitative data obtained in interviews with 25 unincarcerated drug sellers from disadvantaged neighborhoods in St. Louis, Missouri. We find that dealers' use of retaliation is linked to four kinds of deterrence-general, specific, situational, and permeating-and that these are combined into three forms: namely, specific-situational; specific-permeating; and comprehensive (i.e., all four kinds simultaneously). Implications for research, theory, and "criminal justice" are discussed. Specifically, we call for future scholarship to examine how each type of deterrence affects the others, and suggest that both predation against and retaliation by drug dealers might be reduced by granting them greater access to formal means of dispute resolution.

Effects of acoustic deterrents on foraging bats

Johnson, Joshua B.; Ford, W. Mark; Rodrigue, Jane L.; Edwards, John W.

2012-01-01

Significant bat mortality events associated with wind energy expansion, particularly in the Appalachians, have highlighted the need for development of possible mitigation practices to reduce or prevent strike mortality. Other than increasing turbine cut-in speed, acoustic deterrents probably hold the greatest promise for reducing bat mortality. However, acoustic deterrent effectiveness and practicality has not been experimentally examined and is limited to site-specific case studies. Accordingly, we used a crossover experimental design with prior control period to show that bat activity was reduced 17.1 percent by the deployment of ultrasonic deterrents placed around gauged watershed weir ponds on the Fernow Experimental Forest in West Virginia. We caution that while our results should not be extrapolated to the scope of a typical wind energy production facility, the results warrant further research on the use of acoustic deterrents to reduce bat fatalities.

The introduction of a potentially abuse deterrent oxycodone formulation: Early findings from the Australian National Opioid Medications Abuse Deterrence (NOMAD) study.

There is increasing concern about tampering of pharmaceutical opioids. We describe early findings from an Australian study examining the potential impact of the April 2014 introduction of an abuse-deterrent sustained-release oxycodone formulation (Reformulated OxyContin(®)). Data on pharmaceutical opioid sales; drug use by people who inject drugs regularly (PWID); client visits to the Sydney Medically Supervised Injecting Centre (MSIC); and last drug injected by clients of inner-Sydney needle-syringe programmes (NSPs) were obtained, 2009-2014. A cohort of n=606 people tampering with pharmaceutical opioids was formed pre-April 2014, and followed up May-August 2014. There were declines in pharmacy sales of 80mg OxyContin(®) post-introduction of the reformulated product, the dose most commonly diverted and injected by PWID. Reformulated OxyContin(®) was among the least commonly used and injected drugs among PWID. This was supported by Sydney NSP data. There was a dramatic reduction in MSIC visits for injection of OxyContin(®) post-introduction of the new formulation (from 62% of monthly visits pre-introduction to 5% of visits, August 2014). The NOMAD cohort confirmed a reduction in OxyContin(®) use/injection post-introduction. Reformulated OxyContin(®) was cheaper and less attractive for tampering than Original OxyContin(®). These data suggest that, in the short term, introduction of an abuse-deterrent formulation of OxyContin(®) in Australia was associated with a reduction in injection of OxyContin(®), with no clear switch to other drugs. Reformulated OxyContin(®), in this short follow-up, does not appear to be considered as attractive for tampering. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Impact of abuse-deterrent OxyContin on prescription opioid utilization.

Hwang, Catherine S; Chang, Hsien-Yen; Alexander, G Caleb

2015-02-01

We quantified the degree to which the August 2010 reformulation of abuse-deterrent OxyContin affected its use, as well as the use of alternative extended-release and immediate-release opioids. We used the IMS Health National Prescription Audit, a nationally representative source of prescription activity in the USA, to conduct a segmented time-series analysis of the use of OxyContin and other prescription opioids. Our primary time period of interest was 12 months prior to and following August 2010. We performed model checks and sensitivity analyses, such as adjusting for marketing and promotion, using alternative lag periods, and adding extra observation points. OxyContin sales were similar before and after the August 2010 reformulation, with approximately 550 000 monthly prescriptions. After adjusting for declines in the generic extended-release oxycodone market, the formulation change was associated with a reduction of approximately 18 000 OxyContin prescription sales per month (p = 0.02). This decline corresponded to a change in the annual growth rate of OxyContin use, from 4.9% prior to the reformulation to -23.8% during the year after the reformulation. There were no statistically significant changes associated with the sales of alternative extended-release (p = 0.42) or immediate-release (p = 0.70) opioids. Multiple sensitivity analyses supported these findings and their substantive interpretation. The market debut of abuse-deterrent OxyContin was associated with declines in its use after accounting for the simultaneous contraction of the generic extended-release oxycodone market. Further scrutiny into the effect of abuse-deterrent formulations on medication use and health outcomes is vital given their popularity in opioid drug development.

A Biomimetic Ultrasonic Whistle for Use as a Bat Deterrent on Wind Turbines

2016-11-01

As wind energy continues to gain worldwide prominence, more and more turbines are detrimentally influencing bat colonies. In 2012 alone, an estimated 600,000 bats were killed by wind turbines in the United States. Bats show a tendency to fly towards turbines. The objective of this work is to deter bats from the proximity of the swept area of operational wind turbine blades. Established field studies have shown that bats avoid broadband ultrasonic noise on the same frequency spectrum as their echolocation chirps. A biomimetic ultrasonic pulse generator for use as a bat deterrent on wind turbines is designed and studied experimentally. This device, which works based on the fundamentals of flow-induced oscillations of a flexible sheet is a whistle-like device inspired by a bat larynx, mechanically powered via air flow on a wind turbine blade. Current device prototypes have proven robust at producing ultrasound across the 20 - 70 kHz range for flow inlet velocities of 4 - 14 m/s. Ultimately, a deterrent as described here could provide a reliable, cost-effective means of alerting bats to the presence of moving turbine blades, reducing bat mortality at wind facilities, and reducing regulatory uncertainty for wind facility developers. The financial support provided by the US Department of Energy, and the Massachusetts Clean Energy center is acknowledged.

1996-01-01

The globemallow,Sphaeralcea emoryi Torrey, a plant native to Arizona was evaluated as a source of feeding or oviposition deterrents to the boll weevil,Anthonomus grandis Boheman. Feeding and oviposition responses of reproductive weevils to the flower buds and artificial diets spiked with dry powder or extracts of the globemallow buds were determined. Boll weevils were deterred from feeding and ovipositing in the flower buds unless the calyxes were removed. Male and virgin female weevils were discouraged from feeding as much as gravid weevils. Secondary chemicals in the flower buds served primarily as feeding deterrents but also prevented oviposition. The concentration of these chemicals was highest in the calyxes of the buds, and potent deterrent activity could be extracted from the calyxes with methanol. Boll weevils were able to perceive the deterrents by contact chemosensory organs on the antennae, maxillary palps and labial palps.

2017-02-01

The current research examined cultural similarities and differences in punishment beliefs and decisions. Participants were European Americans ( N = 50), Chinese Americans ( N = 57), and Chinese in Mainland China ( N = 50). The Functions of Punishment Questionnaire was used to measure participants' beliefs about the retributive or deterrent functions of punishment and a scenario method was used to measure the extent to which punishment decisions were driven by individuals' concerns for retribution or deterrence. The results indicated that, contrary to the hypothesis that the retributive function would be emphasized by individualistic groups and the deterrent function by collectivistic groups, Mainland Chinese participants had a stronger belief in retribution and a weaker belief in deterrence than did European and Chinese Americans. The results also indicated that retribution played a bigger role in punishment decisions for Chinese than for the other two groups, but the importance of the deterrence function in punishment decisions did not differ across the three groups. Finally, the correlation between interdependence orientation and the belief in retribution was positive for Chinese but negative for European Americans. Taken together, the findings provided little evidence that collectivists are more deterrence-oriented and individualists more retribution-oriented.

Background For the shortage of high-quality general practitioners (GPs) in China's rural areas, Chinese government has taken steps to encourage rural specialists to participate in transition training for future GPs. Specialists’ initial participation motivations and their perceived deterrents during training may play important roles for their learning engagement in the transition training. This study aimed at revealing the relationships among the variables of initial participation motivations, perceived deterrents in training, and learning engagement. Methods A questionnaire survey was used in this study. A total of 156 rural specialists who participated in transition training for future GPs filled out the questionnaire, which consisted of the measurements of initial participation motivations, perceived deterrents, and learning engagement in training. The data about specialists’ demographic variables were collected at the same time. Results The variance of initial escape/stimulations motivation significantly predicted the variance of learning engagement through the full mediating role of perceived deterrents in training. In addition, initial educational preparation motivations predicted the variance of learning engagement directly. Conclusions Specialists’ initial participation motivations and perceived deterrents in training played important roles for learning engagement in the transition training. PMID:27340086

School discipline and disruptive classroom behavior: the moderating effects of student perceptions.

PubMed

Way, Sandra M

2011-01-01

This study examines the relationship between school discipline and student classroom behavior. A traditional deterrence framework predicts that more severe discipline will reduce misbehavior. In contrast, normative perspectives suggest that compliance depends upon commitment to rules and authority, including perceptions of fairness and legitimacy. Using school and individual-level data from the National Education Longitudinal Study of 1988 and multilevel regression modeling, the author finds support for the normative perspective. Students who perceive school authority as legitimate and teacher–student relations as positive are rated as less disruptive. While perceptions of fairness also predict lower disruptions, the effects are mediated by positive teacher–student relations. Contrary to the deterrence framework, more school rules and higher perceived strictness predicts more, not less, disruptive behavior. In addition, a significant interaction effect suggests that attending schools with more severe punishments may have the unintended consequence of generating defiance among certain youth.

Nuclear weapons and medicine: some ethical dilemmas.

PubMed

Haines, A; de B White, C; Gleisner, J

1983-12-01

The enormous destructive power of present stocks of nuclear weapons poses the greatest threat to public health in human history. Technical changes in weapons design are leading to an increased emphasis on the ability to fight a nuclear war, eroding the concept of deterrence based on mutually assured destruction and increasing the risk of nuclear war. Medical planning and civil defence preparations for nuclear war have recently been increased in several countries although there is little evidence that they will be of significant value in the aftermath of a nuclear conflict. These developments have raised new ethical dilemmas for those in health professions. If there is any risk of use of weapons of mass destruction, then support for deterrence with these weapons as a policy for national or global security appears to be incompatible with basic principles of medical ethics and international law. The primary medical responsibility under such circumstances is to participate in attempts to prevent nuclear war.

Community-based participatory research in complex settings: clean mind–dirty hands

2014-01-01

Despite the abundance of the literature which discusses factors supporting or inhibiting effective participation of community members in community-based research, there is a paucity of publications analysing challenges to participation in complex settings. This manuscript describes an intervention built on researcher–community partnership amid complex social conditions which challenged participation of community members at different stages of the research process. The research took place in a Palestinian refugee camp in Beirut, Lebanon and 1 of 12 in Lebanon which suffer from deteriorating social, economic and physical conditions perpetuated by state-imposed restrictions. The research team developed a community coalition which was involved in all stages of planning, designing, implementation and dissemination. In all those stages the aim was to maintain rigorous research, to follow a ‘clean mind’ approach to research, but maintain principles of community participation which necessitate ‘a dirty hand’. Despite commitment to the principles of community-based participatory research, participation of community members (including youth, parents and teachers) was affected to a great extent by the social, physical and structural conditions of the community context. Characteristics of the context where research is conducted and how it affects community members should not be overlooked since multiple factors beyond the researchers' control could interfere with the rigour of scientific research. Researchers need to develop a plan for participation with the community from the beginning with an understanding of the community forces that affect meaningful participation and address possible deterrence.

Preference and aversion for deterrent chemicals in two species of Peromyscus mouse.

Deterrent chemicals such as quinine hydrochloride (QHC1) are generally considered to be aversive to mammals at all detectable concentrations. However, several species contain individuals that drink solutions containing low concentrations of deterrents in preference to plain water. The present study examines this paradoxical preference in two species of mouse, Peromyscus melanotis and P. aztecus. Preliminary findings had suggested that whereas some P. aztecus prefer low concentrations of QHC1, no P. melanotis prefer any concentration of QHC1. Experiment 1 tested the hypothesis that individual mice that prefer low concentrations of QHC1 would respond similarly to four other deterrents described by humans as bitter and/or astringent (ouabain, hop extract, sucrose octaacetate, and tannic acid) in 48-h, two-bottle choice tests. Peromyscus aztecus displayed a large amount of intraspecific variation in response to all five deterrents. Those P. aztecus that drank low concentrations of QHC1 in preference to plain water were significantly more likely to respond similarly to low concentrations of the other deterrents. No P. melanotis displayed a preference for any concentration of either deterrent. Experiment 2 examined the temporal stability of the response to 0.1 mM QHC1 in P. aztecus over six consecutive choice tests. Mice were divided into three groups based on their initial response to the QHC1 solution (preference, no response, or rejection) and then subjected to the 12-day test. The response of mice within each of the groups did not change significantly over time.(ABSTRACT TRUNCATED AT 250 WORDS)

NATO (North Atlantic Treaty Organization) deterrence and defense after the INF (Intermediate-Range Nuclear Forces) treaty. Final report, June 1988-June 1989

The treaty between the Soviet Union and the United States eliminating a whole class of intermediate-range nuclear forces (INF) in Europe raises a number of questions about NATO's future ability to deter Warsaw Pact aggression. Future choices on Alliance strategy and doctrine will be influenced by a variety of factors, including the image of new thinking in Soviet security policy enunciated by General Secretary Gorbachev, changing West European opinion toward the use of nuclear weapons for NATO deterrence, the complications inherent in further nuclear and conventional arms-control negotiations, assessments of the current conventional arms balance in Europe, and ongoing questionsmore » about NATO cohesion as well as the continued coupling of American security with that of her European allies. In the post-INF environment it may well be that U.S. Navy nuclear assets will assume an increasingly important role, particularly the Tomahawk Land Attack Missile/Nuclear (TLAM/N). The TLAM/N has many attractive attributes that can be supportive of NATO deterrence of the WTO, but there are also a number of unresolved questions to be addressed concerning this particular weapons system. Modernization of NATO's land-based short-range nuclear forces (SNF), such as the Lance missile, is also seen by many as critical to the maintenance of Alliance security in the aftermath of INF.« less

Blunt impact as deterrent: human approach-avoidance behaviors and other stress responses studied within a paintball gaming context

NASA Astrophysics Data System (ADS)

Short, Kenneth R.; Bergen, Michael T.; DeMarco, Robert M.; Chua, Florence B.; Servatius, Richard J.

2006-05-01

Blunt impact munitions are often used by civilian law enforcement and in military operations on urban terrain (MOUT) missions to dissuade individuals and groups from approaching valued assets. The use of blunt munitions (rubber-ball or sponge) is predicated on their effectiveness as aversive stimuli; the effectiveness is weighed against the risk of serious injury or death. However, little empirical evidence supports effectiveness. Here, we use a paintball gaming context to study the effects of blunt impact on performance and approach behaviors. Volunteers individually traversed a course in which targets offer the opportunity to gain for accuracy. While completing the targeting task, subjects were bombarded with paintballs, which progressively became more numerous and the impact more intense as the subjects neared goal locations. Initial data suggest that over 30 blunt impacts by paintballs delivered at 280 ft/sec over 30 to 100 ft are insufficient to overcome intrinsic and extrinsic approach motivations or impair targeting or advance performance in an overwhelming majority of subjects. Our apparent ceiling effect was surprising. A sub-comparison of the few subjects who stopped the game before the end with those who did not suggests that personality factors influence the effectiveness of blunt impact as a deterrent. While paintballs differ from traditional blunt impact munitions on a number of physical characteristics, impact that was sufficient to repeatedly bruise volunteers was not an effective deterrent.

Current Impact and Application of Abuse-Deterrent Opioid Formulations in Clinical Practice.

PubMed

Lee, Ya-Han; Brown, Daniel L; Chen, Hsiang-Yin

2017-11-01

Abuse-deterrent formulations (ADFs) represent one novel strategy for curbing the potential of opioid abuse. We aim to compare and contrast the characteristics and applications of current abuse-deterrent opioid products in clinical practice. Literature searches were conducted in databases (Pubmed Medline, International Pharmaceutical Abstracts, Google Scholar) and official reports. Relevant data were screened and organized into: 1) epidemiology of opioid abuse, 2) mitigation strategies for reducing opioid abuse, 3) development of ADFs, and 4) clinical experience with these formulations. Increasing trends of opioid abuse and misuse have been reported globally. There are 5 types of abuse-deterrent opioid products: physical chemical barrier, combined agonist/antagonist, sequestered aversive agent, prodrug, and novel delivery system. The advantages and disadvantages of the 5 options are discussed in this review. A total of 9 products with abuse-deterrent labels have been approved by the Food and Drug Administration (FDA). The rates of abuse, diversion, and overdose deaths of these new products are also discussed. A framework for collecting in-time data on the efficacy, benefit and risk ratio, and cost-effectiveness of these new products is suggested to facilitate their optimal use. The present review did not utilize systematic review standards or meta-analytic techniques, given the large heterogeneity of data and outcomes reviewed. ADFs provide an option for inhibiting the abuse or misuse of oral opioid products by hindering extraction of the active ingredient, preventing alternative routes of administration, or causing aversion. Their relatively high costs, uncertain insurance policies, and limited data on pharmacoeconomics warrant collaborative monitoring and assessment by government agencies, pharmaceutical manufacturers, and data analysis services to define their therapeutic role in the future.

Isolation and Identification of Mosquito (Aedes aegypti) Biting-Deterrent Compounds from the Native American Ethnobotanical Remedy Plant Hierochloë odorata (Sweetgrass).

PubMed

Cantrell, Charles L; Jones, A Maxwell P; Ali, Abbas

2016-11-09

Hierochloë odorata (L.) P. Beauv. (Poaceae), commonly known as sweetgrass, has documented use as an insect repellent by the Flatheads of Montana and Blackfoot of Alberta. Both the Flatheads of Montana and Blackfoot of Alberta would use braided plant material in a sachet in clothing or burn them from one end as incense, air/clothing freshener, and insect repellent. This study evaluated the insect-repellent properties of this plant using an in vitro mosquito Aedes aegypti feeding bioassay-directed approach to identify the compound(s) responsible for the observed activities. Evaluation of crude extracts produced from H. odorata revealed that the hydrodistillate had the highest level of mosquito biting deterrence. Fractionation of this extract, followed by re-evaluation for mosquito biting deterrence, produced many active fractions, which were evaluated by spectroscopic techniques and determined to contain phytol, coumarin, and 2-methoxy-4-vinylphenol. Phytol and coumarin were both determined to be responsible for the Ae. aegypti biting deterrency. Scientific evidence reported here validates its traditional use as a biting-insect deterrent.

Cyber Deterrence and Stability

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

Goychayev, Rustam; Carr, Geoffrey A.; Weise, Rachel A.

Throughout the 20th and early 21st centuries, deterrence and arms control have been cornerstones of strategic stability between the superpowers. However, the weaponization of the cyber realm by State actors and the multipolar nature of cyber conflict now undermines that stability. Strategic stability is the state in which nations believe that if they act aggressively to undermine U.S. national interests and the post-World War II liberal democratic order, the consequences will outweigh the benefits. The sense of lawlessness and lack of consequences in the cyber realm embolden States to be more aggressive in taking actions that undermine stability. Accordingly, thismore » paper examines 1) the role of deterrence and arms control in securing cyber stability, and 2) the limitations and challenges associated with these traditional national security paradigms as applied to this emerging threat domain. This paper demonstrates that many 20th-century deterrence and arms control concepts are not particularly applicable in the cyber realm. However, they are not entirely irrelevant. The United States can distill lessons learned from this rich deterrence and arms control experience to develop and deploy a strategy to advance cyber stability.« less

Oviposition deterrent and skin repellent activities of Solanum trilobatum leaf extract against the malarial vector Anopheles stephensi.

PubMed Central

Rajkumar, S.; Jebanesan, A.

2005-01-01

The leaf extract of Solanum trilobatum (Solanaceae) was tested under laboratory conditions for oviposition deterrent and skin repellent activities against the adult mosquito Anopheles stephensi. Concentrations of 0.01, 0.025, 0.05, 0.075 and 0.1% reduced egg laying by gravid females from 18 to 99% compared to ethanol-treated controls. In skin repellent tests, concentrations of 0.001, 0.005, 0.01, 0.015, and 0.02 % provided 70 to 120 minutes protection against mosquito bites, whereas the ethanol control provided only 2.2 minutes of protection. Both oviposition deterrent and skin repellent activity were dose dependent. The results suggest that the leaf extract of S. trilobatum is an effective oviposition deterrent and skin repellent against An. stephensi. PMID:16341247

Abuse-deterrent formulations approval reform: Will clinical correctness or real-world results be used to address the nation's opioid crisis: "Noninterference" as a new approval standard.

PubMed

Cohen, Dan

To further the public policy objectives of Congress and the country, legislators should now insist that abuse-deterrent formulations (ADFs) be deployed for every C-II opioid and stimulant. The need for these innovative technologies has never been greater. And to most efficiently incentivize innovators to develop and deploy the most effective and modern deterrents, a new and simpler regulatory approval standard for ADF should be adopted by the U.S. Food and Drug Administration. That standard, based on a concept of "Noninterference" increases the potential for a much earlier deployment of ADFs in a broad range of products and allows deterrence to play its most effective role in combatting the national opioid crisis.

Deterrence before Hiroshima

Quester, G.H.

The gap between studies of military history and military strategy is ever widening. The enormous destructive power of nuclear weapons has tended to persuade us that the military experience of the first half of this century is not relevant to more ''modern'' military questions. In Deterrence before Hiroshima, first published in 1966, George H. Quester analyzes pre-nuclear age theories of deterrence to equip us with a perspective and data by which current theories can be evaluated. Quester shows that from almost the time of the first military aircraft, air-power was believed to have the capacity for apocalyptic destruction. He pointsmore » out that the modern terms deterrence, limited war, tacit agreement, and balance of terror, show up often in the literature from 1900-1945, coupled with war scenarios every bit as awesome as a nuclear holocaust.« less

Effect of qualitative and quantitative variation in allelochemicals on a generalist insect: Iridoid glycosides and the southern armyworm.

PubMed

Puttick, G M; Bowers, M D

1988-01-01

The behavioral and physiological effects of plant allelochemicals have been difficult to demonstrate; it is not often clear whether the compounds are deterrent, toxic, or both. In this study, we compared the qualitative and quantitative effects of several iridoid glycosides on a generalist lepidopteran herbivore,Spodoptera eridania (Noctuidae). Larval growth and survivorship and larval preference or avoidance were measured on artificial diets containing different iridoid glycosides at different concentrations. We also tested the toxicity/deterrence of these compounds. We found that iridoid glycosides retarded larval growth significantly at relatively low concentrations and that they were usually avoided in preference tests. The toxicity/ deterrence test did not always reflect the results of these other tests. The merits of using a variety of methods for determining deterrence and/or toxicity of plant allelochemicals are discussed.

Age, gender and deterrability: Are younger male drivers more likely to discount the future?

Freeman, James; Kaye, Sherrie-Anne; Truelove, Verity; Davey, Jeremy

2017-07-01

Utilizing the Classical Deterrence theory and Stafford and Warr's (1993) reconceptualized model of deterrence, the current study examined whether age, gender, and discounting the future tendencies influence perceptions of being apprehended for speeding offences. Licensed motorists (N=700; 57% female) in Queensland (Australia) were recruited to complete a self-report questionnaire that measured perceptual deterrence, speeding related behaviors and discounting the future tendencies. Data were analyzed utilizing descriptive, bivariate and multivariate regressions. Significant (albeit weak) positive correlations were found between age and perceptions of apprehension certainty. Males were significantly more likely to report higher incidences of speeding (including while avoiding detection) compared to females. In contrast, females were more likely to perceive high levels of apprehension certainty and consider impending penalties to be more severe. At a multivariate level, discounting the future tendencies (in addition to being male, reporting lower levels of perceptual severity and swiftness, and more instances of punishment avoidance) were predictive of lower perceptual certainty levels. This study is one of the first to reveal that being male and having a tendency to discount the consequences of the future may directly influence drivers' perceptual deterrence levels.

Nuclear weapons and medicine: some ethical dilemmas.

PubMed Central

Haines, A; de B White, C; Gleisner, J

1983-01-01

The enormous destructive power of present stocks of nuclear weapons poses the greatest threat to public health in human history. Technical changes in weapons design are leading to an increased emphasis on the ability to fight a nuclear war, eroding the concept of deterrence based on mutually assured destruction and increasing the risk of nuclear war. Medical planning and civil defence preparations for nuclear war have recently been increased in several countries although there is little evidence that they will be of significant value in the aftermath of a nuclear conflict. These developments have raised new ethical dilemmas for those in health professions. If there is any risk of use of weapons of mass destruction, then support for deterrence with these weapons as a policy for national or global security appears to be incompatible with basic principles of medical ethics and international law. The primary medical responsibility under such circumstances is to participate in attempts to prevent nuclear war. PMID:6668585

Frequency modulation for a wind turbine blade-mounted ultrasonic bat deterrent

2017-11-01

Progress on developing a bat deterrent device for placement on the rotating blades of a wind turbine is presented. The mechanisms by which bat larynxes generate ultrasound is studied and reproduced experimentally. In previous iterations, flow-induced oscillations have been used to generate ultrasonic frequencies within the 20-70 kHz range: a range which laboratory studies have shown can deter bats from an area. However, the present work considers mechanisms which result in frequency modulation within the higher harmonics, an acoustic signal closer to what bats naturally avoid. Results discussed include the effects of spanwise tension on the flapwise oscillation of a pseudo larynx in flow, and how shifting the flapwise natural frequency allows frequency modulation. The net effect is a device effective within the range of wind speeds encountered along the length of a rotating wind turbine blade.

Taste detection of the non-volatile isothiocyanate moringin results in deterrence to glucosinolate-adapted insect larvae.

Isothiocyanates (ITCs), released from Brassicales plants after hydrolysis of glucosinolates, are known for their negative effects on herbivores but mechanisms have been elusive. The ITCs are initially present in dissolved form at the site of herbivore feeding, but volatile ITCs may subsequently enter the gas phase and all ITCs may react with matrix components. Deterrence to herbivores resulting from topically applied volatile ITCs in artificial feeding assays may hence lead to ambiguous conclusions. In the present study, the non-volatile ITC moringin (4-(α-L-rhamnopyranosyloxy)benzyl ITC) and its glucosinolate precursor glucomoringin were examined for effects on behaviour and taste physiology of specialist insect herbivores of Brassicales. In feeding bioassays, glucomoringin was not deterrent to larvae of Pieris napi (Lepidoptera: Pieridae) and Athalia rosae (Hymenoptera: Tenthredinidae), which are adapted to glucosinolates. Glucomoringin stimulated feeding of larvae of the related Pieris brassicae (Lepidoptera: Pieridae) and also elicited electrophysiological activity from a glucosinolate-sensitive gustatory neuron in the lateral maxillary taste sensilla. In contrast, the ITC moringin was deterrent to P. napi and P. brassicae at high levels and to A. rosae at both high and low levels when topically applied to cabbage leaf discs (either 12, 120 or 1200 nmol moringin per leaf disc of 1cm diameter). Survival of A. rosae was also significantly reduced when larvae were kept on leaves treated with moringin for several days. Furthermore, moringin elicited electrophysiological activity in a deterrent-sensitive neuron in the medial maxillary taste sensillum of P. brassicae, providing a sensory mechanism for the deterrence and the first known ITC taste response of an insect. In simulated feeding assays, recovery of moringin was high, in accordance with its non-volatile nature. Our results demonstrate taste-mediated deterrence of a non-volatile, natural ITC to glucosinolate-adapted insects. Copyright © 2015 Elsevier Ltd. All rights reserved.

(E)-Caryophyllene and α-Humulene: Aedes aegypti Oviposition Deterrents Elucidated by Gas Chromatography-Electrophysiological Assay of Commiphora leptophloeos Leaf Oil

Aedes aegypti is responsible for the transmission of dengue, a disease that infects millions of people each year. Although essential oils are well recognized as sources of compounds with repellent and larvicidal activities against the dengue mosquito, much less is known about their oviposition deterrent effects. Commiphora leptophloeos, a tree native to South America, has important pharmacological properties, but the chemical profile and applicability of its essential oil in controlling the spread of the dengue mosquito have not been investigated. The aim of this study was to determine the composition of C. leptophloeos leaf oil and to evaluate its larvicidal and oviposition deterrent effects against A. aegypti. Fifty-five components of the essential oil were detected by gas chromatography (GC)—mass spectrometry, with α-phellandrene (26.3%), (E)-caryophyllene (18.0%) and β-phellandrene (12.9%) identified as the major constituents. Bioassays showed that the oil exhibited strong oviposition deterrent effects against A. aegypti at concentrations between 25 and 100 ppm, and possessed good larvicidal activity (LC50 = 99.4 ppm). Analysis of the oil by GC coupled with electroantennographic detection established that seven constituents could trigger antennal depolarization in A. aegypti gravid females. Two of these components, namely (E)-caryophyllene and α-humulene, were present in substantial proportions in the oil, and oviposition deterrence assays confirmed that both were significantly active at concentrations equivalent to those present in the oil. It is concluded that these sesquiterpenes are responsible, at least in part, for the deterrent effect of the oil. The oviposition deterrent activity of the leaf oil of C. leptophloeos is one of the most potent reported so far, suggesting that it could represent an interesting alternative to synthetic insecticides. The results of this study highlight the importance of integrating chemical and electrophysiological methods for screening natural compounds for their potential in combating vectors of insect-borne diseases.

2017-10-01

Five flavonoids from hops, two of their derivatives, along with naringenin used as a model compound, were tested for their antifeedant activity against three coleopteran stored product pests: Sitophilus granarius L., Tribolium confusum Duv. and Trogoderma granarium Everts. The introduction, into the tested flavonoid molecules, of additional structural fragments such as prenyl or dimethylpyran moiety, is proposed to significantly alter the deterrent activity of the compounds. The prenyl moiety in flavonoids increased the deterrent activity of these compounds in all three of the grain feeding species used in the tests. It is also concluded that the introduction of dimethylpyran moiety to the flavonoid structure increases its deterrent activity in S. granarius and T. confusum, but in one of the test insects, T. granarium, an increased feeding was observed in response to the introduction of dimethylpyran moiety to the flavonoid structure.

Reductions without Regret: Avoiding Wrong Turns, Roach Motels, and Box Canyons

Swegle, John A.; Tincher, Douglas J.

This is the third of three papers (in addition to an introductory summary) aimed at providing a framework for evaluating future reductions or modifications of the U.S. nuclear force, first by considering previous instances in which nuclear-force capabilities were eliminated; second by looking forward into at least the foreseeable future at the features of global and regional deterrence (recognizing that new weapon systems currently projected will have expected lifetimes stretching beyond our ability to predict the future); and third by providing examples of past or possible undesirable outcomes in the shaping of the future nuclear force, as well as somemore » closing thoughts for the future. In this paper, we provide one example each of our judgments on what constitutes a box canyon, a roach motel, and a wrong turn: Wrong Turn: The Reliable Replacement Warhead: Roach Motel: SRAM T vs the B61: and A Possible Box Canyon: A Low-Yield Version of the W76 SLBM Warhead. Recognizing that new nuclear missions or weapons are not demanded by current circumstances ₋ a development path that yields future capabilities similar to those of today, which are adequate if not always ideal, and a broader national-security strategy that supports nonproliferation and arms control by reducing the role for, and numbers, of nuclear weapons ₋ we briefly consider alternate, less desirable futures, and their possible effect on the complex problem of regional deterrence. In this regard, we discuss the issues posed by, and possible responses to, three example regional deterrence challenges: in-country defensive use of nuclear weapons by an adversary; reassurance of U.S. allies with limited strategic depth threatened by an emergent nuclear power; and extraterritorial, non-strategic offensive use of nuclear weapons by an adversary in support of limited military objectives against a U.S. ally.« less

Little Boy to Star Wars the evolution of American deterrence. Research report

1986-05-01

The historical and sociological development of the American deterrent posture in the nuclear age is traced since the its dawn at Alamagordo, New Mexico, 16 July 1945, and the use of the Little Boy over Hiroshima three weeks later. A description of Western man's involvement in and reaction to pre-1945 catastrophic circumstances is followed by a comparative examination of the post-1945 changes in national policy in regard to the use and dangers of total war. Using Bernard Brodie as a theoretical deterrent baseline, the author analyzes the ethical and military shifts in U.S. declaratory (versus actual) nuclear policy, through Paulmore » Nitze's statements of future policy in light of strategic defense. The author concludes that extremely effective--not necessarily perfect--defenses can be based dramatically on the beneficial effects of arms control. But at the same time, such a condition must inevitably result in a de facto reversion of U.S. nuclear policy to that of a small, non-counterforce force de frappe deterrent - similar in effect to that of the present French posture. The implications of this upon U.S.-Soviet force balance, the historical trends of the American Way of War, and the present deterrent mindset of the officer corps is left as a grave concern.« less

Bumblebees are not deterred by ecologically relevant concentrations of nectar toxins.

PubMed

Tiedeken, Erin Jo; Stout, Jane C; Stevenson, Philip C; Wright, Geraldine A

2014-05-01

Bees visit flowers to collect nectar and pollen that contain nutrients and simultaneously facilitate plant sexual reproduction. Paradoxically, nectar produced to attract pollinators often contains deterrent or toxic plant compounds associated with herbivore defence. The functional significance of these nectar toxins is not fully understood, but they may have a negative impact on pollinator behaviour and health, and, ultimately, plant pollination. This study investigates whether a generalist bumblebee, Bombus terrestris, can detect naturally occurring concentrations of nectar toxins. Using paired-choice experiments, we identified deterrence thresholds for five compounds found in the nectar of bee-pollinated plants: quinine, caffeine, nicotine, amygdalin and grayanotoxin. The deterrence threshold was determined when bumblebees significantly preferred a sucrose solution over a sucrose solution containing the compound. Bumblebees had the lowest deterrence threshold for the alkaloid quinine (0.01 mmol l(-1)); all other compounds had higher deterrence thresholds, above the natural concentration range in floral nectar. Our data, combined with previous work using honeybees, suggest that generalist bee species have poor acuity for the detection of nectar toxins. The fact that bees do not avoid nectar-relevant concentrations of these compounds likely indicates that it is difficult for them to learn to associate floral traits with the presence of toxins, thus maintaining this trait in plant populations.

Rapid Deterioration of Basic Life Support Skills in Dentists With Basic Life Support Healthcare Provider.

PubMed

Nogami, Kentaro; Taniguchi, Shogo; Ichiyama, Tomoko

2016-01-01

The aim of this study was to investigate the correlation between basic life support skills in dentists who had completed the American Heart Association's Basic Life Support (BLS) Healthcare Provider qualification and time since course completion. Thirty-six dentists who had completed the 2005 BLS Healthcare Provider course participated in the study. We asked participants to perform 2 cycles of cardiopulmonary resuscitation on a mannequin and evaluated basic life support skills. Dentists who had previously completed the BLS Healthcare Provider course displayed both prolonged reaction times, and the quality of their basic life support skills deteriorated rapidly. There were no correlations between basic life support skills and time since course completion. Our results suggest that basic life support skills deteriorate rapidly for dentists who have completed the BLS Healthcare Provider. Newer guidelines stressing chest compressions over ventilation may help improve performance over time, allowing better cardiopulmonary resuscitation in dental office emergencies. Moreover, it may be effective to provide a more specialized version of the life support course to train the dentists, stressing issues that may be more likely to occur in the dental office.

Routes of abuse of prescription opioid analgesics: a review and assessment of the potential impact of abuse-deterrent formulations.

PubMed

Gasior, Maciej; Bond, Mary; Malamut, Richard

2016-01-01

Prescription opioid analgesics are an important treatment option for patients with chronic pain; however, misuse, abuse and diversion of these medications are a major global public health concern. Prescription opioid analgesics can be abused via intended and non-intended routes of administration, both intact or after manipulation of the original formulation to alter the drug-delivery characteristics. Available data indicate that ingestion (with or without manipulation of the prescribed formulation) is the most prevalent route of abuse, followed by inhalation (snorting, smoking and vaping) and injection. However, reported routes of abuse vary considerably between different formulations. A number of factors have been identified that appear to be associated with non-oral routes of abuse, including a longer duration of abuse, younger age, male sex and a rural or socially deprived location. The development of abuse-deterrent formulations of prescription opioid analgesics is an important step toward reducing abuse of these medications. Available abuse-deterrent formulations aim to hinder extraction of the active ingredient, prevent administration through alternative routes and/or make abuse of the manipulated product less attractive, less rewarding or even aversive. There are currently five opioid analgesics with a Food and Drug Administration abuse-deterrent label, and a number of other products are under review. A growing body of evidence suggests that introduction of abuse-deterrent opioid analgesics in the USA has been associated with decreased rates of abuse of these formulations. The availability of abuse-deterrent formulations therefore appears to represent an important step toward curbing the epidemic of abuse of prescription opioid analgesics, while ensuring the availability of effective pain medications for patients with legitimate medical need.

Mitigating the Impact of Bats in Historic Churches: The Response of Natterer’s Bats Myotis nattereri to Artificial Roosts and Deterrence

Bats frequently roost in historic churches, and these colonies are of considerable conservation value. Inside churches, bat droppings and urine can cause damage to the historic fabric of the building and to items of cultural significance. In extreme cases, large quantities of droppings can restrict the use of a church for worship and/or other community functions. In the United Kingdom, bats and their roosts are protected by law, and striking a balance between conserving the natural and cultural heritage can be a significant challenge. We investigated mitigation strategies that could be employed in churches and other historic buildings to alleviate problems caused by bats without adversely affecting their welfare or conservation status. We used a combination of artificial roost provision and deterrence at churches in Norfolk, England, where significant maternity colonies of Natterer’s bats Myotis nattereri damage church features. Radio-tracking data and population modelling showed that excluding M. nattereri from churches is likely to have a negative impact on their welfare and conservation status, but that judicious use of deterrents, especially high intensity ultrasound, can mitigate problems caused by bats. We show that deterrence can be used to move bats humanely from specific roosting sites within a church and limit the spread of droppings and urine so that problems to congregations and damage to cultural heritage can be much reduced. In addition, construction of bespoke roost spaces within churches can allow bats to continue to roost within the fabric of the building without flying in the church interior. We highlight that deterrence has the potential to cause serious harm to M. nattereri populations if not used judiciously, and so the effects of deterrents will need careful monitoring, and their use needs strict regulation.

Abuse, misuse, addiction, overdose, and death associated with non-medical use of prescription opioids have become a serious public health concern. Reformulation of these products with abuse-deterrent properties is one approach for addressing this problem. FDA has approved several extended-release opioid analgesics with abuse-deterrent labeling, the bases of which come from pre-market studies. As all opioid analgesics must be capable of delivering the opioid in order to reduce pain, abuse-deterrent properties do not prevent abuse, nor do pre-market evaluations ensure that there will be reduced abuse in the community. Utilizing data from various surveillance systems, some recent post-market studies suggest a decline in abuse of extended-release oxycodone after reformulation with abuse-deterrent properties. We discuss challenges stemming from the use of such data. We quantify the relationship between the sample, the population, and the underlying sampling mechanism and identify the necessary conditions if valid statements about the population are to be made. The presence of other interventions in the community necessitates the use of comparators. We discuss the principles under which the use of comparators can be meaningful. Results based on surveillance data need to be interpreted with caution as the underlying sampling mechanisms can bias the results in unpredictable ways. The use of comparators has the potential to disentangle the effect due to the abuse-deterrence properties from those due to other interventions. However, identifying a comparator that is meaningful can be very difficult. Published 2017. This article is a U.S. Government work and is in the public domain in the USA.

Coping with mass destruction: United States power projection in the nuclear and chemical third world. Monograph report

Cheek, G.H.

1993-05-14

This monograph explores the proliferation of weapons of mass destruction in the Third World, their operational impact on power projection forces, and the viability of deterrence in the future. It concludes that the proliferation of weapons of mass destruction may have grave consequences for the power projection forces in the future; simple assumptions of non-use, reliance on our nuclear deterrent or protective measures may give us a false sense of security. Proper analysis of operational vulnerabilities will be essential for future power projection. Proliferation of operational delivery systems and weapons of mass destruction continues despite treaties and the best intentionsmore » of world leaders. Weapons of mass destruction are becoming more common throughout the world and chemical and biological weapons continue to become more and more lethal. These trends are creating a multipolar world, which history has shown to be the most unstable. This unstable world will be the environment for future power projection. Deterrence in this environment is without precedent other than the Cold War paradigm. It is questionable whether deterrence will transfer outside this paradigm as Third World nations do not have the experience, balance of power, infrastructure or political stability needed to make the concept viable. Possession of weapons of mass destruction may even allow these nations to deter entry of US power projection forces into certain regions as deterrence is a two way concept. While deterrence is still an essential part of US National Strategy to prevent war, reliance on it to prevent use of weapons of mass destruction in the midst of a conflict may prove to be a false hope.« less

Nectar Attracts Foraging Honey Bees with Components of Their Queen Pheromones.

PubMed

Liu, Fanglin; Gao, Jie; Di, Nayan; Adler, Lynn S

2015-11-01

Floral nectar often contains chemicals that are deterrent to pollinators, presenting potential challenges to outcrossing plant species. Plants may be able to co-opt pollinator chemical signals to mitigate the negative effects of nectar deterrent compounds on pollination services. We found that buckwheat (Fagopyrum esculentum) and Mexican sunflower (Tithonia diversifolia) produce nectar with abundant phenolics, including three components of the Apis honeybee queen mandibular pheromone (QMP). In addition, these nectars contain a non-pheromonal phenolic, chlorogenic acid (CA), which was toxic to honeybees, and T. diversifolia nectar also contained isochlorogenic acid (IA). Fresh nectar or solutions containing nectar phenolics reduced Apis individual feeding compared to sucrose solutions. However, freely foraging bees preferred solutions with QMP components to control solutions, and QMP components over-rode or reversed avoidance of CA and IA. Furthermore, prior exposure to the presence or just the odor of QMP components removed the deterrent effects of CA and IA. By mimicking the honey bee pheromone blend, nectar may maintain pollinator attraction in spite of deterrent nectar compounds.

The effect of an abuse‐deterrent opioid formulation (OxyContin) on opioid abuse‐related outcomes in the postmarketing setting

2016-01-01

An extended‐release opioid analgesic (OxyContin, OC) was reformulated with abuse‐deterrent properties to deter abuse. This report examines changes in abuse through oral and nonoral routes, doctor‐shopping, and fatalities in 10 studies 3.5 years after reformulation. Changes in OC abuse from 1 year before to 3 years after OC reformulation were calculated, adjusted for prescription changes. Abuse of OC decreased 48% in national poison center surveillance systems, decreased 32% in a national drug treatment system, and decreased 27% among individuals prescribed OC in claims databases. Doctor‐shopping for OC decreased 50%. Overdose fatalities reported to the manufacturer decreased 65%. Abuse of other opioids without abuse‐deterrent properties decreased 2 years later than OC and with less magnitude, suggesting OC decreases were not due to broader opioid interventions. Consistent with the formulation, decreases were larger for nonoral than oral abuse. Abuse‐deterrent opioids may mitigate abuse and overdose risks among chronic pain patients. PMID:27170195

"Selling smarter, not harder": Life course effects on drug sellers' risk perceptions and management.

PubMed

Fader, Jamie J

2016-10-01

Policies undergirding the American War on Drugs assume that drug offenders respond rationally to adjustments in sanction certainty and severity. Previous studies find that instead of absolute deterrence, or the termination of criminal activity, drug offenders employ restrictive deterrence, or a variety of risk management strategies. Extant research and current drug policy both fail to examine the interaction of risk perception, management techniques, and life course events or circumstances. This dynamic examination of apprehension avoidance strategies relies on in-depth interviews mapping out the careers of 20 drug sellers in Philadelphia, Pennsylvania. It examines their risk perceptions and risk management strategies and techniques, exploring rationales for shifts in offending behavior. Respondents were highly risk-averse but used a narrow definition of sanctions relevant to shaping future offending behavior, typically making small adjustments in sales techniques. Rationales for these shifts included sanctions, personal preference, and life course events or circumstances. Only one attributed lasting desistance from offending to a sanction, although life course events such as parenthood and employment were associated with short-term and planned desistance. The limited relevance of sanctions to offenders' thinking about risk avoidance contextualizes the widespread failure of policies designed to deter drug sales. Findings support a growing conclusion that severity of punishment is a less powerful deterrent than certainty and that adjustments in certainty after arrest are offense-specific. The relationship of life course events - especially employment - to desistance and resumed offending suggest that social policies may be more effective than criminal justice sanctions in reducing drug offending.

Essential oils and extract of Curcuma longa, ar-turmerone, and curcuminoids were evaluated for their larvicidal and deterrent activity against mosquitoes. Ar-turmerone and curcuminoids constituted 36.9, 24.9 and 50.6% of rhizome oil, leaf oil, and rhizome extract, respectively. Ar-turmerone was the major compound of the rhizome oil (36.9%) and leaf oil (24.9%). The ethanolic extract had 15.4% ar-turmerone with 6.6% bisdesmethoxycurcumin, 6.1% desmethoxycurcumin, and 22.6% curcumin. In in vitro studies, essential oils of the leaf (biting deterrence index [BDI] = 0.98), rhizome (BDI = 0.98), and rhizome ethanolic extract (BDI = 0.96) at 10 µg/cm(2) showed biting deterrent activity similar to DEET at 25 nmol/cm(2) against Aedes aegypti L. Among the pure compounds, ar-turmerone (BDI = 1.15) showed the biting deterrent activity higher than DEET at 25 nmol/cm(2) whereas the activity of other compounds was lower than DEET. In Anopheles quadrimaculatus Say, only ar-turmerone showed deterrent activity similar to DEET. In dose-response bioassay, ar-turmerone showed significantly higher biting deterrence than DEET at all the dosages. Ar-turmerone, at 15 nmol/cm(2), showed activity similar to DEET at 25 nmol/cm(2) and activity at 5 nmol/cm(2) was similar to DEET at 20 and 15 nmol/cm(2). Leaf essential oil with LC(50) values of 1.8 and 8.9 ppm against larvae of An. quadrimaculatus and Ae. aegypti, respectively, showed highest toxicity followed by rhizome oil and ethanolic extract. Among the pure compounds, ar-turmerone with LC(50) values of 2.8 and 2.5 ppm against larvae of An. quadrimaculatus and Ae. aegypti, respectively, was most toxic followed by bisdesmethoxycurcumin, curcumin, and desmethoxycurcumin. © The Authors 2015.

Do deterrence and social-control theories predict driving after drinking 15 years after a DWI conviction?

PubMed

Lapham, Sandra C; Todd, Michael

2012-03-01

This study investigates the utility of deterrence and social-control theories for prospective prediction of driving-while-impaired (DWI) outcomes of first-time DWI offenders. The sample consisted of a subset of 544 convicted first-time DWI offenders (N=337 females) who were interviewed 5 and 15 years after referral to a Screening Program in Bernalillo County, New Mexico. Variables collected at the 5-year (initial) interview were used in structural equation models to predict past 3-months, self-reported DWI at the 15-year follow-up (follow-up) interview. These variables represented domains defined by deterrence and social-control theories of DWI behavior, with one model corresponding to deterrence theory and one to social-control theory. Both models fit the data. DWI jail time was positively related to perceived enforcement, which was negatively but not significantly related to self-reported DWI. Neither jail time for DWI nor perceived likelihood of arrest was linearly related to self-reported DWI at follow-up. Interactions between jail time and prior DWI behavior indicated relatively weaker associations between initial and 15-year DWI for those reporting more jail time. Our prospective study demonstrated that for this convicted DWI offender cohort, classic formulations of deterrence and social-control theories did not account for DWI. However, results suggest that punishment may decrease the likelihood of DWI recidivism. Copyright © 2012 Elsevier Ltd. All rights reserved.

Do Work Characteristics Predict Health Deterioration Among Employees with Chronic Diseases?

de Wind, Astrid; Boot, Cécile R L; Sewdas, Ranu; Scharn, Micky; van den Heuvel, Swenne G; van der Beek, Allard J

2018-06-01

Purpose In our ageing workforce, the increasing numbers of employees with chronic diseases are encouraged to prolong their working lives. It is important to prevent health deterioration in this vulnerable group. This study aims to investigate whether work characteristics predict health deterioration over a 3-year period among employees with (1) chronic diseases, and, more specifically, (2) musculoskeletal and psychological disorders. Methods The study population consisted of 5600 employees aged 45-64 years with a chronic disease, who participated in the Dutch Study on Transitions in Employment, Ability and Motivation (STREAM). Information on work characteristics was derived from the baseline questionnaire. Health deterioration was defined as a decrease in general health (SF-12) between baseline and follow-up (1-3 years). Crude and adjusted logistic regression analyses were performed to investigate prediction of health deterioration by work characteristics. Subgroup analyses were performed for employees with musculoskeletal and psychological disorders. Results At follow-up, 19.2% of the employees reported health deterioration (N = 1075). Higher social support of colleagues or supervisor predicted health deterioration in the crude analyses in the total group, and the groups with either musculoskeletal or psychological disorders (ORs 1.11-1.42). This effect was not found anymore in the adjusted analyses. The other work characteristics did not predict health deterioration in any group. Conclusions This study did not support our hypothesis that work characteristics predict health deterioration among employees with chronic diseases. As our study population succeeded continuing employment to 45 years and beyond, it was probably a relatively healthy selection of employees.

Refugee blues: a UK and European perspective

PubMed Central

Turner, Stuart

2015-01-01

In this paper, the numbers of refugees travelling to the European Union are set in a global context. It is argued that the increasing restrictions placed on asylum seekers from the 1980s onwards in the UK and the associated culture of deterrence and prohibition have had the perverse effect of supporting the economic market for people smuggling. It appears that these restrictions were initially designed to deter people, most of whom would have been granted humanitarian assistance had they managed to arrive in the UK, so as to prevent them from accessing the decision-making process on asylum. Policy changes concerning travel, benefits, and other pressures on asylum seekers are also considered in the context of deterrence. The problems facing asylum seekers do not end with their arrival in a safe country. The current methods of determining refugee status are alarmingly weak. Indeed there is evidence suggesting that those who are most traumatised before arrival face systematic disadvantage. The focus of this paper is on the United Kingdom but its conclusions apply to most Western European countries. The paper concludes with some tentative suggestions for change. PMID:26514159

Churches and nuclear deterrence

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

van Voorst, L.B.

In contrast to a history of support for our nation's involvement in wars, US churches are now in the process of edging toward a direct confrontation with the Reagan Administration over nuclear weapons and deterrence policy. This new attitude is attributed to two main factors: the growing awareness of the end of American strategic superiority and the concern over the Reagan Administration's attitude toward strategic nuclear issues. This newly widespread determination among the churches to challenge public policy on nuclear issues is addressed by examining the various churches and their efforts in the anti-nuclear movement. The Catholic Bishops' Draft Pastoralmore » Letter is discussed at length and is considered to be the most radical effort by any American church to define moral standards for the nuclear era. In contrast, the historical Protestant treatment differs considerably from the Catholic initiative; it started earlier but has been more fragmented and disparate. Only the American Jewish community as a whole has been, with a few notable exceptions, reluctant to become involved in the movement. The ultimate political question raised is how this religious involvement will influence American strategic nuclear doctrines. 27 references.« less

This project assessed unmet psychosocial needs of kidney transplant recipients and the feasibility of a support group located at an urban Canadian hospital to meet those needs. A survey assessed transplant recipient concerns about psychosocial issues related to transplantation, interest in a support group, desired group composition, facilitation, leadership, barriers and alternative forms of support. Most respondents were more than two years since transplant and were more concerned about medical complications, returning to normalcy, and had a greater desire to talk to other transplant recipients. Forty per cent of respondents indicated they would be interested in a support group. However, 60% indicated that a support group hosted in the hospital setting would be a deterrent to attending, citing time and transportation as the greatest barriers. More research is needed to assess the feasibility of post-kidney transplant support groups closer to recipients' homes and the feasibility of alternative forms of support.

2006-09-01

A set of 14 plant lectins was screened in a binary choice bioassay for inhibitory activity on cowpea weevil Callosobruchus maculatus (F.) oviposition. Coating of chickpea seeds (Cicer arietinum L.) with a 0.05% (w/v) solution of plant lectins caused a significant reduction in egg laying. Control experiments with heat inactivated lectin and BSA indicated that the observed deterrent effects are specific and require carbohydrate-binding activity. However, no clear correlation could be established between deterrent activity and sugar-binding specificity/molecular structure of the lectins. Increasing the insect density reduced the inhibitory effect of the lectins confirming that female insects are capable of adjusting their oviposition rates as a function of host availability.

Risk based In Vitro Performance Assessment of Extended Release Abuse Deterrent Formulations

Xu, Xiaoming; Gupta, Abhay; Al-Ghabeish, Manar; Calderon, Silvia N.; Khan, Mansoor A.

2016-01-01

High strength extended release opioid products, which are indispensable tools in the management of pain, are associated with serious risks of unintentional and potentially fatal overdose, as well as of misuse and abuse that might lead to addiction. The issue of drug abuse becomes increasingly prominent when the dosage forms can be readily manipulated to release a high amount of opioid or to extract the drug in certain products or solvents. One approach to deter opioid drug abuse is by providing novel abuse deterrent formulations (ADF), with properties that may be viewed as barriers to abuse of the product. However, unlike regular extended release formulations, assessment of ADF technologies are challenging, in part due to the great variety of formulation designs available to achieve deterrence of abuse by oral, parenteral, nasal and respiratory routes. With limited prior history or literature information, and lack of compendial standards, evaluation and regulatory approval of these novel drug products become increasingly difficult. The present article describes a risk-based standardized in-vitro approach that can be utilized in general evaluation of abuse deterrent features for all ADF products. PMID:26784976

South Africa has a markedly skewed representation where the majority of blood (62%) is presently collected from an ethnically White minority. This study seeks to identify culturally specific factors affecting motivation of donors in South Africa. We performed a qualitative study to evaluate motivators and deterrents to blood donation among Black South Africans. A total of 13 focus groups, comprising a total of 97 Black South Africans, stratified by age and geographic location were conducted. Transcripts of the interviews were analysed using a coding framework by Bednall & Bove. Participants made 463 unique comments about motivators focusing primarily on promotional communications (28%), incentives (20%) and prosocial motivation (16%). Participants made 376 comments about deterrents which focused primarily on fear (41%), negative attitudes (14%) and lack of knowledge (10%). Although prosocial motivation (altruism) was the most frequently mentioned individual motivator, promotional communication elicited more overall comments by participants. As reported by many authors, fear and lack of awareness were strong deterrents, but scepticism engendered by perceived racial discrimination in blood collection were unique to the South African environment. © 2015 British Blood Transfusion Society.

The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated with either of the test formulations, which led to significantly higher ovipositional avoidance when compared with female lice on control hair tufts. Additionally, both formulations were determined to be competent infestation deterrents in a competitive avoidance test in the presence of a known attractant (head louse feces extract). In in vivo assessments using a previously validated poultry model, Elimax shampoo was determined to be an efficacious deterrent against poultry chewing lice within Menopon spp. and Menacanthus spp. PMID:26336209

Thinking Globally about U.S. Extended Deterrence

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

Roberts, Brad; Santoro, David; Volpe, Tristan

In contrast to the Cold War bilateral global competition between the United States and the Soviet Union, the modern nuclear age features a more complex, multiplayer arena on the regional scale. With the exception of the U.S. and Russia, most major powers retain relatively small nuclear arsenals or technical hedge capabilities. The U.S., with strong interests and security partnerships in Europe, Northeast Asia, and the Middle East, must navigate through long-standing rivalries and active conflicts while attempting to divine the intentions of less experienced nuclear decision makers in charge of weak domestic institutions. As a result, analysts and policymakers mustmore » think globally about U.S. extended deterrence. How have the requirements of extended deterrence and assurance changed? Are there important threads that connect each region? What should the U.S. do differently? To explore these questions, Lawrence Livermore National Laboratory’s Center for Global Security Research, in partnership with the Carnegie Endowment for International Peace and the Pacific Forum CSIS, held a workshop on “Thinking Globally about U.S. Extended Deterrence” in Washington, DC on November 2, 2015. The workshop brought together approximately 40 U.S. and foreign deterrence specialists and government officials, all attending in their private capacities. The participants joined a day of not-for-attribution discussions on the changing deterrence and assurance requirements, the threads that connect the regions, and U.S. strategy to deal with emerging challenges.

Opioids with abuse-deterrent properties: A regulatory and technological overview.

PubMed

Haddox, J David

Three concurrent public health problems coexist in the United States: endemic nonmedical use/misuse of opioid analgesics, epidemic overdose fatalities involving opioid analgesics, and endemic chronic pain in adults. These intertwined issues comprise an opioid crisis that has spurred the development of formulations of opioids with abuse-deterrent properties and label claims (OADP). To reduce abuse and misuse of prescription opioids, the federal Food and Drug Administration (FDA) has issued a formal Guidance to drug developers that delineates four categories of testing to generate data sufficient for a description of a product's abuse-deterrent properties, along with associated claims, in its Full Prescribing Information (FPI). This article reviews the epidemiology of the crisis as background for the development of OADP, summarizes the FDA Guidance for Industry regarding abuse-deterrent technologies, and provides an overview of some technologies that are currently employed or are under study for incorporation into OADP. Such technologies include physical and chemical barriers to abuse, combined formulations of opioid agonists and antagonists, inclusion of aversive agents, use of delivery systems that deter abuse, development of new molecular entities and prodrugs, and formulation of products that include some combination of these approaches. Opioids employing these novel technologies are one part of a comprehensive intervention strategy that can deter abuse of prescription opioid analgesics without creating barriers to the safe use of prescription opioids. The maximal public health contribution of OADP will probably occur only when all opioids have FDA-recognized abuse-deterrent properties and label claims.

Administrative license suspension: Does length of suspension matter?

PubMed

Fell, James C; Scherer, Michael

2017-08-18

Administrative license revocation (ALR) laws, which provide that the license of a driver with a blood alcohol concentration at or over the illegal limit is subject to an immediate suspension by the state department of motor vehicles, are an example of a traffic law in which the sanction rapidly follows the offense. The power of ALR laws has been attributed to how swiftly the sanction is applied, but does the length of suspension matter? Our objectives were to (a) determine the relationship of the ALR suspension length to the prevalence of drinking drivers relative to sober drivers in fatal crashes and (b) estimate the extent to which the relationship is associated to the general deterrent effect compared to the specific deterrent effect of the law. Data comparing the impact of ALR law implementation and ALR law suspension periods were analyzed using structural equation modeling techniques on the ratio of drinking drivers to nondrinking drivers in fatal crashes from the Fatality Analysis Reporting System (FARS). States with an ALR law with a short suspension period (1-30 days) had a significantly lower drinking driver ratio than states with no ALR law. States with a suspension period of 91-180 days had significantly lower ratios than states with shorter suspension periods, while the three states with suspension lengths of 181 days or longer had significantly lower ratios than states with shorter suspension periods. The implementation of any ALR law was associated with a 13.1% decrease in the drinking/nondrinking driver fatal crash ratio but only a 1.8% decrease in the intoxicated/nonintoxicated fatal crash ratio. The ALR laws and suspension lengths had a significant general deterrent effect, but no specific deterrent effect. States might want to keep (or adopt) ALR laws for their general deterrent effects and pursue alternatives for specific deterrent effects. States with short ALR suspension periods should consider lengthening them to 91 days or longer.

Ageing doctors.

PubMed

Lillis, Steven; Milligan, Eleanor

2017-03-01

Doctors are neither more nor less susceptible than the general population to the effects of ageing. The relevance of deterioration with age depends on the nature of the work undertaken. Reduced muscle strength and visual and auditory deterioration can compromise clinical ability. Accumulation of chronic disease further reduces capacity. Cognitive decline is of particular importance, as good medical care requires considerable cognitive function. Patient safety is paramount, yet older doctors are an important part of the medical workforce and their value should be recognised. Changes in patient case mix, work place support systems and individual adjustments can assist safe practice. Deterioration in health should be acknowledged and requires proactive management. Current methods of ensuring competence are inadequate for supporting ageing doctors. A new initiative is recommended comprising collaboration between regulators, colleges and employing institutions to support the ageing doctor in providing safe and effective practice. © 2017 AJA Inc.

Gender and stereotypes in motivation to study computer programming for careers in multimedia

NASA Astrophysics Data System (ADS)

Doubé, Wendy; Lang, Catherine

2012-03-01

A multimedia university programme with relatively equal numbers of male and female students in elective programming subjects provided a rare opportunity to investigate female motivation to study and pursue computer programming in a career. The MSLQ was used to survey 85 participants. In common with research into deterrence of females from STEM domains, females displayed significantly lower self-efficacy and expectancy for success. In contrast to research into deterrence of females from STEM domains, both genders placed similar high values on computer programming and shared high extrinsic and intrinsic goal orientation. The authors propose that the stereotype associated with a creative multimedia career could attract female participation in computer programming whereas the stereotype associated with computer science could be a deterrent.

Addiction, overdoses and deaths resulting from prescription opioids have increased dramatically over the last decade. In response, several manufacturers have developed formulations of opioids with abuse-deterrent properties. For many of these products, the Food and Drug Administration (FDA) recognized the formulation with labeling claims and mandated post-marketing studies to assess the abuse-deterrent effects. In response, we assess differences in rates of opioid-related overdoses and poisonings prior to and following the introduction of a formulation of OxyContin® with abuse-deterrent properties. To assess effects of this formulation, electronic medical record (EMR) data from Kaiser Permanente Northwest (KPNW) and Kaiser Permanente Northern California (KPNC) are linked to state death data and compared to chart audits. Overdose and poisoning events will be categorized by intentionality and number of agents involved, including illicit drugs and alcohol. Using 6-month intervals over a 10-year period, trends will be compared in rates of opioid-related overdoses and poisoning events associated with OxyContin® to rates of events associated with other oxycodone and opioid formulations. Qualitative interviews with patients and relatives of deceased patients will be conducted to capture circumstances surrounding events. This study assesses and tracks changes in opioid-related overdoses and poisoning events prior to and following the introduction of OxyContin® with abuse-deterrent properties. Public health significance is high because these medications are designed to reduce abuse-related behaviors that lead to important adverse outcomes, including overdoses and deaths.

Abuse-deterrent formulations: transitioning the pharmaceutical market to improve public health and safety

Worthy, Stacey L.; Barnes, Michael C.; Tarbell, Benjamin

2015-01-01

This article evaluates abuse-deterrent formulations (ADFs) as a method to reduce prescription drug abuse while ensuring access to vital medications for individuals with legitimate need; assesses the pros and cons of ADFs and the current state of ADF adoption in the market; and develops policy recommendations to transition the market to ADFs. Although abuse-deterrent technology is still in its nascent stages, ADFs have been proven to reduce prescription drug abuse and its consequences, and even an incremental reduction in abuse can have a significant impact on the nation by reducing the costly social, physical, mental, and public health problems resulting from abuse. Federal ADF policy does not reflect the urgency of the prescription drug abuse epidemic and does not go far enough toward changing the status quo. Policies must be implemented to encourage innovation and a market shift toward ADFs by ensuring any generic medication that references a branded ADF demonstrates that it does not have abuse-deterrent properties inferior to the branded ADF product. Policies must also require federal prescription drug benefit plans to cover ADFs to ensure consumers have access to such medications. PMID:25922655

Age differences in understanding precedent-setting decisions and authorities' responses to violations of deontic rules.

PubMed

Klaczynski, Paul A

2011-05-01

To examine age trends in precedent-setting decisions and the effects of these decisions on perceptions of authorities, preadolescents and adolescents were presented with deontic rule infractions that occurred in the absence or presence of mitigating circumstances. In Study 1, in the absence of mitigating circumstances, adolescents recommended punishing rule violations more than preadolescents; when mitigating circumstances were present, adolescents recommended punishing infractions less than preadolescents. In Study 2, before and after receiving information that authorities had punished or permitted rule violations, participants indicated their beliefs in authority legitimacy, rule strength, and rule deterrence value. In the absence of mitigating circumstances, beliefs strengthened when infractions were punished and beliefs weakened when infractions were permitted. When mitigating circumstances were present and authorities punished violations, preadolescents' legitimacy and deterrence beliefs strengthened. Adolescents' deterrence beliefs strengthened, but their beliefs in authority legitimacy weakened. When justifiable infractions were permitted, preadolescents' legitimacy and deterrence beliefs weakened, whereas adolescents' beliefs strengthened. Discussion focuses on age differences in legitimacy beliefs and understanding the consequences of setting precedents and on the relevance of the findings to theories of deontic reasoning, moral judgments, and epistemological development.

The impact of state laws protecting abortion clinics and reproductive rights on crimes against abortion providers: deterrence, backlash, or neither?

PubMed

Pridemore, William Alex; Freilich, Joshua D

2007-12-01

Since Roe v. Wade, most states have passed laws either restricting or further protecting reproductive rights. During a wave of anti-abortion violence in the early 1990s, several states also enacted legislation protecting abortion clinics, staff, and patients. One hypothesis drawn from the theoretical literature predicts that these laws provide a deterrent effect and thus fewer anti-abortion crimes in states that protect clinics and reproductive rights. An alternative hypothesis drawn from the literature expects a backlash effect from radical members of the movement and thus more crimes in states with protective legislation. We tested these competing hypotheses by taking advantage of unique data sets that gauge the strength of laws protecting clinics and reproductive rights and that provide self-report victimization data from clinics. Employing logistic regression and controlling for several potential covariates, we found null effects and thus no support for either hypothesis. The null findings were consistent across a number of different types of victimization. Our discussion contextualizes these results in terms of previous research on crimes against abortion providers, discusses alternative explanations for the null findings, and considers the implications for future policy development and research.

Local governments’ dependence on tobacco tax revenue: a deterrent to tobacco control in the Republic of Korea

PubMed Central

Park, Kidong

2009-01-01

Abstract Objective To investigate, in the Republic of Korea, whether local governments’ participation in an anti-smoking programme supported by the National Health Promotion Fund in 2002–2003 was related to the percentage of local tax revenue comprised by the tobacco consumption tax (TCT). Methods Using financial and administrative data on 163 municipalities, the authors estimated logit models of local governments’ participation in the anti-smoking programme as a function of the proportion of local tax revenue that came from the TCT and a set of control variables, namely local socioeconomic characteristics and the size of the staff in the local public health centre (PHC). Findings Local governments that derived a greater percentage of their local tax revenue from the TCT, particularly those that ranked in the upper fourth in terms of this percentage, were less likely to participate in the anti-smoking programme. Insufficient staff in the PHC was also found to be associated with lower participation in the anti-smoking programme. Conclusion Local governments’ dependence on revenue from the TCT may be a deterrent to tobacco control in the Republic of Korea. PMID:19784449

Predicting DUI decisions in different legal environments: investigating deterrence with a conjoint experiment.

PubMed

Yao, Jie; Johnson, Mark B; Beck, Kenneth H

2014-01-01

Driving under the influence (DUI) enforcement practices and sanctions contribute differentially to the certainty, swiftness, and severity of punishment, which are the key components of general deterrence theory. This study used a conjoint experiment to understand the decision-making process of potential DUI offenders and tested how variation in enforcement and legal punishment affects drinking and driving decisions. It sought to verify and quantify the unique deterrent effects of certainty, severity, and swiftness and to predict the rates of drinking and driving in different legal environments. One hundred twenty-one college seniors and graduate students at the University of Maryland participated in the Web-based conjoint experiment. They were randomly assigned to 4 blocks, each of which included 9 hypothetical scenarios composed of different levels of DUI enforcement and penalties. Respondents were asked to state their likelihood of drinking and driving under each scenario, as well as their estimated chance of being caught by the police for DUI. Intensified enforcement, harsh jail penalty, and immediate long license suspension were found to be the strongest deterrents to drinking and driving. Alternative ways to get home were also important in reducing people's willingness to drive. These factors accounted for most of the attribute effect on the DUI decision, whereas delayed punishment due to judicial processing, fine penalty, and legal blood alcohol concentration (BAC) limit had negligible effects. For the personal characteristics, college seniors and those who had previously driven after drinking were more likely to choose to drink and drive, whereas those who expect a jail penalty for a DUI offense were less likely to drive. Our research confirmed and quantified certainty of punishment as the greatest deterrent to DUI, but it also indicated the equally important effect of a severe jail penalty. It provides evidence on the feasibility of using a conjoint experiment in future studies to understand the general driver population and, with the help of a simulation tool, to predict DUI decisions in different legal environments. Such predictions can be used to better inform policy decisions on developing targeted general deterrence programs in different communities.

Conceptions of politics, morality, and war in the nuclear policy debates

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

Ware, L.C.

1993-01-01

During the resurgent nuclear debates from the mid-1970s to the mid-1980s, analysts sharply disagreed about the appropriate means and ends of strategy. Deterrence dominance strategists argued that America required a countervailing capacity to sustain a viable deterrent posture and to contain Soviet adventurism. Proponents of pure deterrence claimed that the risks endemic to mutual vulnerability would suffice to moderate the superpower rivalry. Advocates of denuclearization charged that reliance on nuclear weaponry posed the greatest danger to human well-being and called for diplomatic measures to establish a disarmament regime. While scholars have systemically explored the strategic and technological components of themore » controversy, few studies have examined the political theoretic dimensions. Through a textual exegesis of the writings of key participants, this work seeks to demonstrate that contending conceptions of politics and morality inform dissension about the viability of coercive power in the nuclear age. Justifications of deterrence dominance proposals generally conflate political and ethical considerations through variants of Hobbesian skepticism or liberal just war interventionism. Such arguments perceive the state as the locus of societal values and sovereignty as sanctioning extensive activities in the global system. Pure deterrence notions posit an irreconcilable tension between politics and morality that corresponds with a tragic vision: war may be a necessary element of sociality, but it seldom has truly creative consequences. From this perspective, the state is a morally ambiguous agent that can preserve and endanger societal well-being. Finally, associated with the denuclearization school is a conviction that progressive social movements can conform politics to essential ethical precepts by minimizing the role of coercive power. In this view, the state and its claim to sovereignty are primary sources of the war system, hence must be radically altered.« less

The deterrent forces of the Commonwealth of Independent States

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

Kortunov, S.

The rapid changes that are occurring in Europe and in the world at large create qualitatively new military and political realities and will force nuclear powers to make major adjustments in their foreign policy and military-technological thinking. The new situation will certainly lead to changes in both the nuclear doctrines of those countries and their approaches to nuclear forces - both strategic and tactical - as will be needed to ensure national security. This applies fully to the Commonwealth of Independent States (the former USSR), whose nuclear doctrine, like that of the North Atlantic Treaty Organization (NATO), is now beingmore » overhauled. It is well known that the former Soviet Union in its public declarations, including those made at the highest political level, has been strongly critical of the doctrine of deterrence. An unbiased historical analysis of the postwar period also demonstrates that military competition between the Soviet Union and the United States in the nuclear field followed the action-reaction logic, the constraining factors being primarily financial and technological rather than moral. Parity was initially interpreted as numerical equality in strategic nuclear arms and later as rough equality in operational nuclear capabilities. Another confirmation that the Soviet Union had based its policy precisely on the doctrine of deterrence is the Antiballistic Missile (ABM) Treaty, which limits the antiballistic missile systems of the two sides to purely symbolic numbers of ABMs and effectively exposes the former Soviet Union and the United States to a retaliatory strike. Nuclear deterrence is a modus vivendi of the world we live in, and it will stay that way until nations devise a fundamentally new system of maintaining international security. The problem is that the nuclear powers have more than enough nuclear weapons to make deterrence work effectively.« less

Off the street and into “the cut”: Deterrence and displacement in NYC's quality of life marijuana policing

PubMed Central

Elliott, Luther; Golub, Andrew; Dunlap, Eloise

2011-01-01

This paper examines the accounts of NYC marijuana smokers about the information and values underlying decisions about where to smoke. We do so to assess the deterrent value of NYC's “quality of life” policing of marijuana in public view. Participants indicated a general awareness of escalated marijuana policing and its attendant risks and almost universally spoke of avoiding public use in high-traffic locations and in the city's cultural and commercial centres. Beyond that, however, the deterrent value of aggressive marijuana policing appears limited. Individuals without access to private space reported outdoor marijuana use as a normalized peer group activity that has increasingly been displaced to marginal and interstitial public spaces that were collectively referred to by participants as “the cut.” PMID:22001856

Strategies to reduce driving under the influence of alcohol.

PubMed

DeJong, W; Hingson, R

1998-01-01

The purpose of this review is to update research on the prevention of alcohol-related traffic deaths since the 1988 Surgeon General's Workshop on Drunk Driving. Four primary areas of research are reviewed here: (a) general deterrence policies, (b) alcohol control policies, (c) mass communications campaigns, including advertising restrictions, and (d) community traffic safety programs. Modern efforts to combat drunk driving in the United States began with specific deterrence strategies to punish convicted drunk drivers, and then evolved to include general deterrence strategies that were targeted to the population as a whole. Efforts next expanded to include the alcohol side of the problem, with measures installed to decrease underage drinking and excessive alcohol consumption. In the next several years, greater efforts are needed on all these fronts. Also needed, however, are programs that integrate drunk driving prevention with other traffic safety initiatives.

A Game Theoretic Model of Thermonuclear Cyberwar

In this paper we propose a formal game theoretic model of thermonuclear cyberwar based on ideas found in [1] and [2]. Our intention is that such a game will act as a first step toward building more complete formal models of Cross-Domain Deterrence (CDD). We believe the proposed thermonuclear cyberwar game is an ideal place to start on such an endeavor because the game can be fashioned in a way that is closely related to the classical models of nuclear deterrence [4–6], but with obvious modifications that will help to elucidate the complexities introduced by a second domain. We startmore » with the classical bimatrix nuclear deterrence game based on the game of chicken, but introduce uncertainty via a left-of-launch cyber capability that one or both players may possess.« less

Deterrence and Risk Preferences in Sequential Attacker-Defender Games with Continuous Efforts.

PubMed

Payyappalli, Vineet M; Zhuang, Jun; Jose, Victor Richmond R

2017-11-01

Most attacker-defender games consider players as risk neutral, whereas in reality attackers and defenders may be risk seeking or risk averse. This article studies the impact of players' risk preferences on their equilibrium behavior and its effect on the notion of deterrence. In particular, we study the effects of risk preferences in a single-period, sequential game where a defender has a continuous range of investment levels that could be strategically chosen to potentially deter an attack. This article presents analytic results related to the effect of attacker and defender risk preferences on the optimal defense effort level and their impact on the deterrence level. Numerical illustrations and some discussion of the effect of risk preferences on deterrence and the utility of using such a model are provided, as well as sensitivity analysis of continuous attack investment levels and uncertainty in the defender's beliefs about the attacker's risk preference. A key contribution of this article is the identification of specific scenarios in which the defender using a model that takes into account risk preferences would be better off than a defender using a traditional risk-neutral model. This study provides insights that could be used by policy analysts and decisionmakers involved in investment decisions in security and safety. © 2017 Society for Risk Analysis.

The Nuclear Posture Review (NPR) : are we safer?

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

Brune, Nancy E.

2010-07-01

Nuclear Posture Review (NPR) is designed to make world safer by reducing the role of U.S. nuclear weapons and reducing the salience of nuclear weapons. U.S. also seeks to maintain a credible nuclear deterrent and reinforce regional security architectures with missile defenses and other conventional military capabilities. But recent studies suggest that nuclear proliferation is a direct response to the perceived threat of U.S. conventional capabilities not U.S. nuclear stockpile. If this is true, then the intent of the NPR to reduce the role and numbers of nuclear weapons and strengthen conventional military capabilities may actually make the world lessmore » safe. First stated objective of NPR is to reduce the role and numbers of U.S. nuclear weapons, reduce the salience of nuclear weapons and move step by step toward eliminating them. Second stated objective is a reaffirmation of U.S. commitment to maintaining a strong deterrent which forms the basis of U.S. assurances to allies and partners. The pathway - made explicit throughout the NPR - for reducing the role and numbers of nuclear weapons while maintaining a credible nuclear deterrent and reinforcing regional security architectures is to give conventional forces and capabilities and missile defenses (e.g. non-nuclear elements) a greater share of the deterrence burden.« less

Deterrent effects of demerit points and license sanctions on drivers' traffic law violations using a proportional hazard model.

PubMed

Lee, Jaeyeong; Park, Byung-Jung; Lee, Chungwon

2018-04-01

Current traffic law enforcement places an emphasis on reducing accident risk from human factors such as drunk driving and speeding. Among the various strategies implemented, demerit points and license sanction systems have been widely used as punitive and educational measures. Limitations, however, exist in previous studies in terms of estimating the interaction effects of demerit points and license sanctions. To overcome such limitations, this work focused on identifying the interaction effects of demerit points and license sanctions on driver traffic violation behavior. The interaction deterrent effects were assessed by using a Cox's proportional hazard model to provide a more accurate and unbiased estimation. For this purpose, five years of driver conviction data was obtained from the Korea National Police Agency (KNPA). This data included personal characteristics, demerit point accumulation and license sanction status. The analysis showed that accumulated demerit points had specific deterrent effects. Additionally, license revocation showed consistent and significant deterrent effects, greater than those for suspension. Male drivers under their 30s holding a motorcycle license were identified as the most violation-prone driver group, suggesting that stricter testing for the acquisition of a motorcycle driver's license is needed.

Laboratory-based testing to evaluate abuse-deterrent formulations and satisfy the Food and Drug Administration's recommendation for Category 1 Testing.

PubMed

Altomare, Christopher; Kinzler, Eric R; Buchhalter, August R; Cone, Edward J; Costantino, Anthony

The US Food and Drug Administration (FDA) considers the development of abuse-deterrent formulations of solid oral dosage forms a public health priority and has outlined a series of premarket studies that should be performed prior to submitting an application to the Agency. Category 1 studies are performed to characterize whether the abuse-deterrent properties of a new formulation can be easily defeated. Study protocols are designed to evaluate common abuse patterns of prescription medications as well as more advanced methods that have been reported on drug abuse websites and forums. Because FDA believes Category 1 testing should fully characterize the abuse-deterrent characteristics of an investigational formulation, Category 1 testing is time consuming and requires specialized laboratory resources as well as advanced knowledge of prescription medication abuse. Recent Advisory Committee meetings at FDA have shown that Category 1 tests play a critical role in FDA's evaluation of an investigational formulation. In this article, we will provide a general overview of the methods of manipulation and routes of administration commonly utilized by prescription drug abusers, how those methods and routes are evaluated in a laboratory setting, and discuss data intake, analysis, and reporting to satisfy FDA's Category 1 testing requirements.

Abuse-deterrent formulations of prescription opioid analgesics in the management of chronic noncancer pain.

Hale, Martin E; Moe, Derek; Bond, Mary; Gasior, Maciej; Malamut, Richard

2016-10-01

Misuse, abuse and diversion of prescription opioid analgesics represent a global public health concern. The development of abuse-deterrent formulations (ADFs) of prescription opioid analgesics is an important step toward reducing abuse and diversion of these medications, as well as potentially limiting medical consequences when misused or administered in error. ADFs aim to hinder extraction of the active ingredient, prevent administration through alternative routes and/or make abuse of the manipulated product less attractive, less rewarding or aversive. However, opioid ADFs may still be abused via the intended route of administration by increasing the dose and/or dosing frequency. The science of abuse deterrence and the regulatory landscape are still relatively new and evolving. This paper reviews the current status of opioid ADFs, with particular focus on different approaches that can be used to deter abuse, regulatory considerations and implications for clinical management.

National military strategy in the post cold war era: Nuclear deterrence or an alternative. Study project

Pooley, G.R.

In the aftermath of the Cold War it becomes necessary to explore the validity of nuclear deterrence as the cornerstone of the United States National Military Strategy for the upcoming period of transition in international relations. Using the current world situation as a starting point, the evolving trends in international relations, arms control and nuclear proliferation, the strategic threat and the evolution of technology will be analyzed in an effort to forecast the complexion of international relations twenty years hence. Then, within this context, nuclear deterrence and a non nuclear alternative nonoffensive defense, proposed by the Danish political scientist, Bjornmore » Moller, will be examined. In the final analysis, this project will suggest an appropriate direction for the evolution of the United States' National Military Strategy which, in the opinion of the author, provides the best probability for long term world peace.« less

Why leaders punish: A power perspective.

PubMed

Mooijman, Marlon; van Dijk, Wilco W; Ellemers, Naomi; van Dijk, Eric

2015-07-01

We propose that power fundamentally changes why leaders punish and we develop a theoretical model that specifies how and why this occurs. Specifically, we argue that power increases the reliance on deterrence, but not just deserts, as a punishment motive and relate this to power fostering a distrustful mindset. We tested our model in 9 studies using different instantiations of power, different measurements and manipulations of distrust while measuring punishment motives and recommended punishments across a number of different situations. These 9 studies demonstrate that power fosters distrust and hereby increases both the reliance on deterrence as a punishment motive and the implementation of punishments aimed at deterrence (i.e., public punishments, public naming of rule breakers and punishments with a mandatory minimum). We discuss the practical implications for leaders, managers and policymakers and the theoretical implications for scholars interested in power, trust, and punishments.

Some Western analysts argue that European security would stabilize if nations shifted to forces and doctrines that left them structurally incapable of conducting offensive military actions. Some, including American scholar Gene Sharp, have even called for replacing traditional military forces with plans for civilian-based resistance. Purely defensive postures would be reassuring to neighboring states, all of these theorists say, but such defenses would still be strong enough to defeat an attack if deterrence failed. This defensive-only stance, according to its advocates, is a purer form of deterrence by denial than now exists, since it removes even the possibility of inflictingmore » punishment in retaliation for an attack: it deters only be denying victory. But Mr. Flanagan questions whether such defense actually would serve as a credible deterrent. In addition, the various proposed schemes share some serious weaknesses, which he proceeds to discuss. 5 refs.« less

''Whither Deterrence?'' A Brief Synopsis May, 2002

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

Poppe, C; Vergino, E; Barker, R

To most audiences, deterrence has been interconnected with nuclear weapons whose purpose had been to deter a Soviet attack. But, the Soviet Union has been gone for almost a decade. President George W. Bush has stated that Russia is not an enemy of the US and the numbers of nuclear weapons can be dramatically reduced. It is important to note that deterrence has always transcended nuclear weapons. The US' first line of deterrence has been its formidable conventional warfare capability, designed to prevent conflict and win wars if necessary. The role of nuclear weapons has been to deter the,use ofmore » nuclear weapons and other weapons of mass destruction against U.S. interests during the conduct of conventional warfare and to ensure our ability to inflict massive destruction on any who would use nuclear weapons, or other weapons of mass destruction, against us. With regard to the Soviet Union, the threat of the use of nuclear weapons was a critical component of our deterrent to prevent massive Soviet conventional attack against our allies in Europe. However, the events of September 11, 2001 make clear that we have not convinced all who seek to harm us that we will be able to respond in a manner to make them wish they had not even tried. The September 11 attacks, as well as other past conflicts, do not mean that deterrence has failed-it remains effective against the threats for which it was designed. We have known there are other threats for which we did not have a credible deterrent. The challenge is to sustain deterrence against the classic threats as they evolve in technical sophistication while remaining alert to the need to evaluate continuously our ability to deter previously unforeseen challenges. How then should we be looking at deterrence as we consider fifteen or so years in the future, say to about 2015? What will be the role of nuclear weapons and other instruments of mass destruction in the future? What should the US be doing to prepare for the future? In this study, we present four futures as a tool for planners who must think ahead fifteen years or more, rather than a prediction of the future. None of the four futures will emerge in just the way we have described. Fifteen years from now, some mix of these futures is more likely, or perhaps we will see a trend towards one of the futures, but with the possibility that any of the other three could appear, perhaps quite swiftly. Any future will undoubtedly contain its own kind of unpleasant surprises and, in contrast to the Cold War; the possession of enormous nuclear-response and conventional-response capability may not be sufficient to deter these from happening. However, there are other tools that the US must include as part of its strategy and security policy in addition to deterrence, specifically dissuasion, defense, destruction, and assurance. Rather than rely on the Cold-War concept of deterrence, future security policy should be built upon the appropriate mix of these elements as a way to steer us toward a more favorable future, while ensuring that we are prepared for the kinds of surprises associated with far less favorable futures. In this study, we have defined three unfavorable futures to be avoided, and one future that represents, we believe, a more desirable global situation than the first three, but still not entirely benign. Our security policy should be defined to avoid or prevent the first three, which we have entitled ''Nuclear Giants, Global Terror'', and ''Regional Nuclear Tension and Use'', and steer us toward a more favorable future, ''Dynamic Cooperation''. We have examined the implications for both policy and military capability that are posed by these different futures. The result often raises more questions than we are able to answer without additional study-however, our primary purpose was to clarify the issues, to identify. what we believe we know, what we don't know, and where more study and effort are needed. Nevertheless, in preparing for unfavorable futures, we must also identify and plan the future we want. This study emphasizes that a desirable future in 2015 would be characterized by peaceful resolution of conflict, growing worldwide economic prosperity, an effective non-proliferation regime, the ability of the United States to control its own destiny without conflict, and expansion of political and economic freedom. Security policies, even in the face of unpleasant futures, should be crafted so as enhance, rather than diminish, these desired goals.« less

The relational underpinnings of quality internal auditing in medical clinics in Israel.

Internal auditing is a key mechanism in enhancing organizational reliability. However, research on the ways quality internal auditing is enabled through learning, deterrence, motivation and process improvement is scant. In particular, the relational underpinnings of internal auditing have been understudied. This study attempts to address this need by examining how organizational trust, perceived organizational support and psychological safety enable internal auditing. Data collected from employees in medical clinics of one of the largest healthcare organizations in Israel at two points in time six months apart. Our results show that organizational trust and perceived organizational support are positively related to psychological safety (measured at time 1), which, in turn, is associated with internal auditing (measured at time 2).

Orangutan trade, confiscations, and lack of prosecutions in Indonesia.

PubMed

Nijman, Vincent

2017-11-01

Prosecuting and sentencing law breakers punishes the offender and acts as a deterrent for future law breakers. With thousands of Sumatran and Bornean orangutans (Pongo abelii and P. pygmaeus) having entered private and government rescue centers and facilities, I evaluate the role of successful prosecution in orangutan conservation in Indonesia. Orangutans have been protected in Indonesian since 1931 and they are not allowed to be traded or to be kept as pets. In the period 1993-2016 at least 440 orangutans were formally confiscated, and many more were "donated" to law enforcement agencies. This resulted in seven (7) successful prosecutions by six different courts. Sentencing was lenient (median fine US$ 442 out of a possible US$ 7,600, median prison sentence 8 months out of a possible 5 years) and certainly too low to act as a deterrent. A paradigm shift within government authorities, conservation organizations, the judiciary, and by the general public is needed where trade in orangutans is no longer seen as a crime against an individual animal but as an economic crime that negatively affects society as a whole. Prosecuting offenders for tax evasion, corruption, endangering public health, animal cruelty, and smuggling, in addition to violating protected species laws, would allow for an increase in sentencing, resulting in a stronger deterrent, and greater public support. Conservation and welfare NGOs have a duty to become more proactive in a drive to increase enforcement; rescuing orangutans always has to coincide with prosecuting offenders and failures, and successes of these prosecutions have to be vigorously publicized. Despite numerous commitments made by Indonesia to orangutan conservation, and clear failures to deliver on almost all components, international donors have increased their funding year on year; it is time that this changes to a system where not failure is rewarded but success. © 2017 Wiley Periodicals, Inc.

Oviposition-altering and ovicidal potentials of five essential oils against female adults of the dengue vector, Aedes aegypti L.

Warikoo, Radhika; Wahab, Naim; Kumar, Sarita

2011-10-01

The oviposition deterrence and ovicidal potential of five different essential oils, peppermint oil (Mentha piperita), basil oil (Ocimum basilicum), rosemary oil (Rosemarinus officinalis), citronella oil (Cymbopogon nardus), and celery seed oil (Apium graveolens), were assessed against female adults of the dengue vector, Aedes aegypti L. Multiple concentration tests were carried out where cups containing 1 mL of different concentrations (100%, 10%, 1%, 0.1%) of the oils and 199 mL of water were used for oviposition. The number of eggs laid and the larvae hatched in each cup were scored to evaluate the oviposition deterrent and ovicidal potentials of the oils. Our investigations revealed that the addition of 100% oil (pure oil) caused complete oviposition deterrence except in A. graveolens which resulted in 75% effective repellency. The use of 10% oil resulted in the maximum deterrence of 97.5% as shown by the M. piperita oil while other oils caused 36-97% oviposition deterrence as against the control. The oviposition medium with 1% oil showed decreased deterrent potential with 30-64% effective repellency, the M. piperita oil being exceptional. However, as the concentrations of the oil were reduced further to 0.1%, the least effective oil observed was A. graveolens (25% ER). Also, the M. piperita oil showed much reduced activity (40%) as compared to the control, while the other oils exhibited 51-58% repellency to oviposition. The studies on the ovicidal effects of these oils revealed that the eggs laid in the water with 100% essential oils did not hatch at all, whereas when 10% oils were used, only the R. officinalis oil resulted in 28% egg hatch. At lower concentrations (1%), the oils of M. piperita, O. basilicum, and C. nardus showed complete egg mortality while those of A. graveolens and R. officinalis resulted in 71% and 34% egg hatches, respectively. When used at 0.1%, the O. basilicum oil was found to be the only effective oil with 100% egg mortality, whereas other oils resulted in 16-76% egg mortality, the least mortality caused by the A. graveolens oil. These results suggest that these essential oils can be employed in a resistance-management program against A. aegypti. Further detailed research is needed to identify the active ingredient in the extracts and implement the effective mosquito management program.

Bed bug deterrence

PubMed Central

2010-01-01

A recent study in BMC Biology has determined that the immature stage of the bed bug (the nymph) signals its reproductive status to adult males using pheromones and thus avoids the trauma associated with copulation in this species. The success of this nymphal strategy of deterrence is instructive. Against the background of increasing problems with bed bugs, this research raises the question whether pheromones might be used to control them.

Donating blood: a meta-analytic review of self-reported motivators and deterrents.

Bednall, Timothy C; Bove, Liliana L

2011-10-01

Although research on blood donor motivation abounds, most studies have typically focused on small sets of variables, used different terminology to label equivalent constructs, and have not attempted to generalize findings beyond their individual settings. The current study sought to synthesize past findings into a unified taxonomy of blood donation drivers and deterrents and to estimate the prevalence of each factor across the worldwide population of donors and eligible nondonors. Primary studies were collected, and cross-validated categories of donation motivators and deterrents were developed. Proportions of first-time, repeat, lapsed, apheresis, and eligible nondonors endorsing each category were calculated. In terms of motivators, first-time and repeat donors most frequently cited convenience, prosocial motivation, and personal values; apheresis donors similarly cited the latter 2 motivators and money. Conversely, lapsed donors more often cited collection agency reputation, perceived need for donation, and marketing communication as motivators. In terms of deterrents, both donors and nondonors most frequently referred to low self-efficacy to donate, low involvement, inconvenience, absence of marketing communication, ineffective incentives, lack of knowledge about donating, negative service experiences, and fear. The integration of past findings has yielded a comprehensive taxonomy of factors influencing blood donation and has provided insight into the prevalence of each factor across multiple stages of donors' careers. Implications for collection agencies are discussed. Copyright © 2011 Elsevier Inc. All rights reserved.

Alpinia officinarum has been confirmed to possess bioactivities against some pests. In this work, a sample was obtained from A. officinarum rhizomes by supercritical fluid CO₂ extraction (SFE). According to GC-MS analysis, the main chemical components for SFE-sample included benzylacetone (26.77%), 1,7-diphenyl-5-hydroxy-3-heptanone (17.78%), guaiacylacetone (10.03%) and benzenepropanal (7.42%). The essential oil of A. officinarum rhizomes (LD 50 = 20.71 μg/adult) exhibited more contact toxicity than SFE extract (LD 50 = 82.72 μg/adult) against Tribolium castaneum . From SFE extracts, one new compound, 1-phenyl-4-(16,17-dimethyl-9,13-octadiene)-5-isopentenyl-7-(4"-methoxyl-3"-hydroxyl-phenyl)-3-heptanone ( 3 ), together with five known compounds identified as 5-hydroxy-1,7-diphenyl-3-heptanone ( 1 ), 1,7-diphenyl-4-hepten-3-one ( 2 ), galangin ( 4 ), galangin-3-methyl ether ( 5 ) and pinocembrin ( 6 ), were isolated and their feeding deterrent activities against T. castaneum adults were assessed. It was found that compounds 1 - 6 had feeding deterrent activities against T. castaneum with feeding deterrent indices of 18.21%, 18.94%, 19.79%, 26.99%, 20.34%, and 35.81%, respectively, at the concentration of 1500 ppm. Hence, the essential oil and SFE extracts/compounds of A. officinarum rhizomes represent promising alternatives in the control of T. castaneum adults.

The effect of oviposition-deterrent and ovicidal of seven essential oils were evaluated towards three mosquito vectors, Aedes aegypti, Anopheles dirus and Culex quinquefasciatus. The oviposition activity index (OAI) values of six essential oils namely Cananga odorata, Cymbopogon citratus, Cymbopogon nardus, Eucalyptus citriodora, Ocimum basilicum and Syzygium aromaticum indicated that there were more deterrent than the control whereas Citrus sinensis oil acted as oviposition attractant. At higher concentration (10%) of Ca. odorata (ylang ylang flowers) showed high percent effective repellency (ER) against oviposition at 99.4% to Ae. aegypti, 97.1% to An. dirus and 100% to Cx. quinquefasciatus, respectively. The results showed that mean numbers of eggs were lower in treated than in untreated water. In addition, there was an inverse relationship between essential oil concentrations and ovicidal activity. As the concentration of essential oil increased from 1%, 5% and up to 10% conc., the hatching rate decreased. The essential oil of Ca. odorata at 10% conc. gave minimum egg hatch of 10.4% (for Ae. aegypti), 0.8% (for An. dirus) and 1.1% (for Cx. quinquefasciatus) respectively. These results clearly revealed that the essential oil of Ca. odorata served as a potential oviposition-deterrent and ovicidal activity against Ae. aegypti, An. dirus and Cx. quinquefasciatus.

Am I my brother's (or customer's or tenant's) keeper? Economic and ethical aspects to the California Supreme Court's struggle with the issue of landowner's standard of care.

PubMed

Hodson, T J; Englander, F; Englander, V

2001-07-01

The Supreme Court of California has ruled on several cases involving the question of to what extent a possessor of land is liable for the harm to customers or tenants occurring when a third party commits a criminal act against the customers or tenants present on the land. This paper reviews the historical development of this aspect of negligence law and analyzes the ethical and economic efficiency implications of ascribing legal responsibility for such crimes to: a) local government, b) the possessor of land, c) the customer, and d) the criminal. For example, is there an effort by the judicial system to substitute deterrence from criminal acts provided by possessors of land (i.e., specific deterrence) for the general deterrence traditionally provided through the use of police powers by local government? Analysis indicates that specific deterrence may be more effective in changing the location of criminal acts than in reducing the level of criminal activities. Also, the expense of complying with the legal responsibilities of protecting customers and clients may be especially high in high-crime, low-income areas, thus forcing commercial establishments to move or go out of business. Thus, we have a troubling tradeoff: compensating individual crime victims in a high-crime area could ultimately deprive the residents of basic economic opportunities.

Why Do Blood Donors Lapse or Reduce Their Donation's Frequency?

Finding effective ways to retain blood donors is crucial. This study seeks to compare, in a context of a voluntary and nonremunerated system, donor demographics and deterrents to blood donation among plasma/platelet donors (PPDs), regular whole blood donors (WBDs), and lapsed whole blood donors (LWBD). Among 1879 participants to a survey on motivations, time use, and blood donation, 207 WBDs (26%) and 148 PPDs (31%) said that they reduced their donation frequency over the last 5 years. Participants to this survey also included 609 LWBDs, who did not donate in the past 5 years. We asked about reasons why they reduce or cease to donate blood and demographic variables. χ(2) Tests were completed to determine which deterrents stand out across the 3 blood donor groups. The deterrent indicating the highest percentage was "time constraints related to work or studies" (43% for all respondents). Comparison of WBDs, LWBDs, and PPDs shows that results for 7 deterrents were statistically different between the 3 groups. Obstacles to donating blood also vary based on sex, age (life course), and level of education. Blood collection agencies should consider developing new retention strategies tailored to blood donors, taking into account the specific profiles of female/male donors, events that typically occur at various stages of life, and particular challenges associated with differences in levels of education.

In this integrative review, we aimed to: first, identify and summarize published studies relating to ward nurses' recognition of and response to patient deterioration; second, to critically evaluate studies that described or appraised the practice of ward nurses in recognizing and responding to patient deterioration; and third, identify gaps in the literature for further research. An integrative review. The Cumulative Index to Nursing and Allied Health Literature (CINAHL) Ovid Medline, Informit and Google Scholar databases were accessed for the years 1990-2014. Data were extracted and summarized in tables and then appraised using the Mixed Method Appraisal Tool. Data were grouped into two domains; recognizing and responding to deterioration and then thematic analysis was used to identify the emerging themes. Seventeen studies were reviewed and appraised. Recognizing patient deterioration was encapsulated in four themes: (1) assessing the patient; (2) knowing the patient; (3) education and (4) environmental factors. Responding to patient deterioration was encapsulated in three themes; (1) non-technical skills; (2) access to support and (3) negative emotional responses. Issues involved in timely recognition of and response to clinical deterioration remain complex, yet patient safety relies on nurses' timely assessments and actions.

Intermediate-range nuclear forces (INF) treaty: History of an illusion

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

Dallas, M.D.

1989-03-01

The purpose of this paper is to examine the Intermediate-Range Nuclear Force (INF) Treaty in historical perspective. The thesis of the paper is that the treaty is an illusion. It is an illusion that promotes the idea that security can be achieved exclusively through arms control, at the expense of balanced and diverse forces across the entire spectrum of deterrence. Although the treaty has been fully ratified, and U.S and Soviet officials have begun the process of destroying launchers, debate still rages in NATO capitals over the treat's impact on alliance security and cohesion. This paper begins with a discussionmore » of the evolution of NATO's deterrent strategy. It continues with a chronology of events leading to the signing of the treaty by President Reagan and General Secretary Gorbachev on December 8, 1987. The paper assesses the military and political impact of the treaty and ends with possible implications for NATO's future and recommendations for further arms control negotiations. The paper concludes that the treaty has not achieved what its supporters claim. In fact the treaty is an arms-control agreement that: (1) is not remotely related to its original purpose; (2) has reinforced NATO military inferiority; and (3) may have laid the groundwork for the unraveling of the Atlantic Alliance.« less

Changes in the dispensing of opioid medications in Canada following the introduction of a tamper-deterrent formulation of long-acting oxycodone: a time series analysis.

In February 2012, a reformulated tamper-deterrent form of long-acting oxycodone, OxyNeo, was introduced in Canada. We investigated the impact of the introduction of OxyNeo on patterns of opioid prescribing. We conducted population-based, cross-sectional analyses of opioid dispensing in Canada between 2008 and 2016. We estimated monthly community pharmacy dispensing of oral formulations of codeine, morphine, hydromorphone and oxycodone, and a transdermal formulation of fentanyl, and converted quantities to milligrams of morphine equivalents (MMEs) per 1000 population. We used time series analysis to evaluate the effect of the introduction of OxyNeo on these trends. National dispensing of long-acting opioids fell by 14.9% between February 2012 and April 2016, from 36 098 MMEs to 30 716 MMEs per 1000 population ( p < 0.01). This effect varied across Canada and was largest in Ontario (reduction of 22.8%) ( p = 0.01) and British Columbia (reduction of 30.0%) ( p = 0.01). The national rate of oxycodone dispensing fell by 46.4% after the introduction of OxyNeo ( p < 0.001); this was partially offset by an increase of 47.8% in hydromorphone dispensing ( p < 0.001). Although dispensing of immediate-release opioids was a substantial contributor to overall population opioid exposure across Canada, it was unaffected by the introduction of OxyNeo ( p > 0.05 in all provinces). The findings suggest that the introduction of a tamper-deterrent formulation of long-acting oxycodone in Canada, against a background of changing public drug benefits, was associated with sustained changes in selection of long-acting opioids but only small changes in the quantity of long-acting opioids dispensed. This illustrates the limited effect a tamper-deterrent formulation and associated coverage policy can have when other, non-tamper-deterrent alternatives are readily available.

Large numbers of bats are killed by wind turbines worldwide and minimizing fatalities is critically important to bat conservation and acceptance of wind energy development. We implemented a 2-year study testing the effectiveness of an ultrasonic acoustic deterrent for reducing bat fatalities at a wind energy facility in Pennsylvania. We randomly selected control and treatment turbines that were searched daily in summer and fall 2009 and 2010. Estimates of fatality, corrected for field biases, were compared between treatment and control turbines. In 2009, we estimated 21-51% fewer bats were killed per treatment turbine than per control turbine. In 2010, we determined an approximate 9% inherent difference between treatment and control turbines and when factored into our analysis, variation increased and between 2% more and 64% fewer bats were killed per treatment turbine relative to control turbines. We estimated twice as many hoary bats were killed per control turbine than treatment turbine, and nearly twice as many silver-haired bats in 2009. In 2010, although we estimated nearly twice as many hoary bats and nearly 4 times as many silver-haired bats killed per control turbine than at treatment turbines during the treatment period, these only represented an approximate 20% increase in fatality relative to the pre-treatment period for these species when accounting for inherent differences between turbine sets. Our findings suggest broadband ultrasound broadcasts may reduce bat fatalities by discouraging bats from approaching sound sources. However, effectiveness of ultrasonic deterrents is limited by distance and area ultrasound can be broadcast, in part due to rapid attenuation in humid conditions. We caution that an operational deterrent device is not yet available and further modifications and experimentation are needed. Future efforts must also evaluate cost-effectiveness of deterrents in relation to curtailment strategies to allow a cost-benefit analysis for mitigating bat fatalities.

Steps reducing reliance on deployed nuclear weapons en route to zero will be discussed. They include broadly enhancing cooperation and transparency agreements beyond the provisions for verifying limits on deployed strategic nuclear warheads and delivery systems in the New START treaty. Two questions that will be addressed are: What conditions would have to be established in order to maintain strategic stability among nations as nuclear weapons recede in importance? What would nuclear deterrence be like in a world without nuclear weapons?

To provide an overview of available abuse-deterrent opioids (ADOs) and the labeling text that describes abuse-deterrent (AD) properties. A nonsystematic review of ADO literature and regulatory documents guiding their development. A critical assessment and discussion of common routes of opioid abuse, AD methods and properties, US Food and Drug Administration (FDA) study requirements to achieve AD labeling, and brief guide to understanding AD labels. The FDA has issued guidance as incentive and direction to industry to develop ADOs as one component of a multi-pronged public-health strategy to combat opioid abuse and misuse. The guidance describes separate categories of premarket and postmarket studies and makes recommendations for claims that may be made based on study findings. Ten ADOs have FDA-approved labeling attesting to AD properties. Available formulations that fail to conform to FDA guidance in study and labeling recommendations cannot be considered ADO. Formulations with AD properties are expected to reduce risk compared to the same agents without AD properties but cannot prevent all abuse and adverse clinical outcomes.

Active travel has been linked with improved transportation and health outcomes, such as reduced traffic congestion and air pollution, improved mobility, accessibility, and equity, and increased physical and mental health. The purpose of this study was to better understand active travel characteristics, motivators, and deterrents in the El Paso, TX, region. A multimodal transportation survey brought together elements of transportation and health, with a focus on attitudinal characteristics. The analysis consisted of an initial descriptive analysis, spatial analysis, and multivariate binary and ordered-response models of walking and bicycling behavior. The motivators and deterrents of active travel differed for walkers, bicyclists, and noncyclists interested in bicycling. The link between active travel and life satisfaction was moderated by age, with a negative association for older travelers. This effect was stronger for bicycling than it was for walking. Based on the findings, several interventions to encourage walking and bicycling were suggested. These included infrastructure and built environment enhancements, workplace programs, and interventions targeting specific subpopulations.

There is no greater public health threat at this time in America than the opioid abuse crisis, and a systematic, level-headed, coherent, and unified approach is needed. Among the many things that have been proposed to help reduce opioid abuse is the development of opioid analgesic products in abuse-deterrent formulations (ADFs). This seems to make perfect sense. Areas covered: In this article, the viewpoints of 12 stakeholders (physicians, pain patients, payers, manufacturers, regulators, law enforcement, hospitals, first responders, elected officials, rehabilitation centers, opioid addicts, and the general public) were considered in terms of how ADF opioids are regarded and might contribute potential impediments to more widespread use. This is a narrative review based on the literature. Stakeholders were not surveyed directly. Expert opinion: Although abuse-deterrent technology for opioid analgesics has been available for several years, ADFs have not gained widespread acceptance. ADF products serve an important but limited purpose, but their incremental costs may serve as a 'mixed message' for many of the stakeholders concerned about cost containment.

Picking up the shield: Incorporating defense into strategic nuclear doctrine. Research report

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

Ruotsala, M.G.

Picking up the Shield is an interesting and enlightening account of the evolution of strategic nuclear doctrine. It puts the offense-defense relationship into a historical perspective that lends important insight into the ongoing debate over strategic defenses. Although this debate centers on the active defenses contemplated by the strategic defense initiative, Lt Col Michael G. Ruotsala makes the point that passive defenses are also an important component of strategic defense. He sees the inherent passive defenses of the Triad as being a key to maintaining offense-oriented deterrence, and he makes a good case for survivable Peacekeeper basing and a smallmore » mobile intercontinental ballistic missile (ICBM) to enhance deterrence and pave the way for active defense. Although the future may hold a strategic defense with new, even revolutionary, weapons, any future program will embody old concepts of offense and defense. For the foreseeable future, offensive strategic forces will continue to play a dominant role in US defense policy. However, strategic defenses are consistent with US strategic doctrine. More important for deterrence, defenses are consistent with Soviet doctrine. Clearly, complementing roles for both the offense and defense are critical for developing a doctrine that enhances deterrence of a nuclear exchange between the United States and the Soviet Union. It is also clear that Picking up the Shield makes a significant contribution to understanding the challenge we face as we incorporate defense into strategic nuclear doctrine.« less

A survey of contemporary West European perspectives on defense, deterrence, and strategy, with special emphasis on the role of nuclear weapons deployed in, or assigned to, the NATO area. Changes have occurred during the past decade in the relative military strength of NATO and the Warsaw Pact, particularly as a result of the substantial growth in Soviet nuclear-capable systems and conventional forces assigned to Europe, and the momentum manifested by the Soviet Union in its deployments of intercontinental ballistic missiles. There has also been a substantial shift in West European thinking and attitudes about security and strategy. Together, these trendsmore » have created a need to reassess the posture of NATO forces generally, and especially nuclear weapons, both in a broader Euro-strategic framework and on the Central Front in the 1980s. The survey is on such issues as the future of the British and French national strategic nuclear forces; the role of the U.S.-strategic nuclear forces in the deterrence of conflict in Europe; the prospects of raising the nuclear threshold by the deployment of new conventional technologies; the impact of strategic defense initiatives on U.S.-NATO security; and the modernization of NATO intermediate-range nuclear capabilities, especially in light of the continuing deployment of the Soviet Union of new generation Euro-strategic forces targeted against Western Europe.« less

Packaging: a grounded theory of how to report physiological deterioration effectively.

PubMed

Andrews, Tom; Waterman, Heather

2005-12-01

The aim of this paper is to present a study of how ward-based staff use vital signs and the Early Warning Score to package physiological deterioration effectively to ensure successful referral to doctors. The literature tends to emphasize the identification of premonitory signs in predicting physiological deterioration. However, these signs lack sensitivity and specificity, and there is evidence that nurses rely on subjective and subtle indicators. The Early Warning Score was developed for the early detection of deterioration and has been widely implemented, with various modifications. The data reported here form part of a larger study investigating the practical problems faced by general ward staff in detecting physiological deterioration. During 2002, interviews and observations were carried out using a grounded theory approach, and a total of 44 participants were interviewed (30 nurses, 7 doctors and 7 health care support workers). Participants reported that quantifiable evidence is the most effective means of referring patients to doctors, and the Early Warning Score achieves this by improving communication between professionals. Rather than reporting changes in individual vital signs, the Early Warning Score effectively packages them together, resulting in a much more convincing referral. It gives nurses a precise, concise and unambiguous means of communicating deterioration, and confidence in using medical language. Thus, nurses are empowered and doctors can focus quickly on identified problems. The Early Warning Score leads to successful referral of patients by providing an agreed framework for assessment, increasing confidence in the use of medical language and empowering nurses. It is essential that nurses and nursing students are supported in its use and in developing confidence in using medical language by continued emphasis on physiology and pathophysiology in the nursing curriculum.

Human-elephant conflict in western Thailand: Socio-economic drivers and potential mitigation strategies

Understanding human-wildlife conflict is an important first step in the conservation of highly endangered species that can have adverse effects on human communities, such as elephants. To gain insights into variables that shape attitudes toward elephant conservation in Asia, we surveyed 410 households and 46 plantation owners in seven villages around the Salakpra Wildlife Sanctuary in western Thailand, an area of high human-elephant conflict. We sought to evaluate how past experiences with elephants (positive or negative), as well as socio-economic variables (age, income level, gender, and employment type) affect attitudes toward elephant conservation and coexistence in this area. In addition, we quantified deterrence methods currently used and identify potential mitigation strategies supported by community members. In general, less supportive attitudes toward elephant conservation and coexistence were held by individuals older than 35 years of age, those who had previously had experienced negative interactions with elephants, those with lower incomes, and those working in the agricultural sector. Conversely, those who had received benefits from living near elephants (e.g., supplemental income or feelings of pride from hosting volunteers or participating in conservation work) had more supportive views of elephant coexistence. Plantation owners reported using a variety of deterrence methods with varying success, with firecrackers being the most commonly utilized method. Community members identified several potentially beneficial mitigation strategies including forest restorations and patrol teams, adding water sources to wild elephant habitat, and education of local school and community groups. Overall, our results highlight the value of community members receiving benefits from living near elephants and suggest that special incentives may be needed for demographic groups disproportionately affected by elephants (e.g. those at lower income levels, those working in agriculture). A combination of these and other approaches will be required if human-elephant coexistence in western Thailand is to be realized. PMID:29856740

The Bald and Golden Eagle Protection Act (BGEPA) prohibits the 'take' of these birds. The act defines take as to 'pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, destroy, molest or disturb.' The 2009 Eagle Permit Rule (74 FR 46836) authorizes the U.S. Fish and Wildlife Service (USFWS) to issue nonpurposeful (i.e., incidental) take permits, and the USFWS 2013 Eagle Conservation Plan Guidance provides a voluntary framework for issuing programmatic take permits to wind facilities that incorporate scientifically supportable advanced conservation practices (ACPs). Under these rules, the Service can issue permits that authorize individual instances of take ofmore » bald and golden eagles when the take is associated with, but not the purpose of, an otherwise lawful activity, and cannot practicably be avoided. To date, the USFWS has not approved any ACPs, citing the lack of evidence for 'scientifically supportable measures.' The Eagle Detection and Deterrents Research Gaps and Solutions Workshop was convened at the National Renewable Energy Laboratory in December 2015 with a goal to comprehensively assess the current state of technologies to detect and deter eagles from wind energy sites and the key gaps concerning reducing eagle fatalities and facilitating permitting under the BGEPA. During the workshop, presentations and discussions focused primarily on existing knowledge (and limitations) about the biology of eagles as well as technologies and emerging or novel ideas, including innovative applications of tools developed for use in other sectors, such as the U.S. Department of Defense and aviation. The main activity of the workshop was the breakout sessions, which focused on the current state of detection and deterrent technologies and novel concepts/applications for detecting and minimizing eagle collisions with wind turbines. Following the breakout sessions, participants were asked about their individual impressions of the relative priority of each of the existing and novel ideas.« less

Optimal pricing and marketing planning plays an essential role in production decisions on deteriorating items. This paper presents a mathematical model for a three-level supply chain, which includes one producer, one distributor and one retailer. The proposed study considers the production of a deteriorating item where demand is influenced by price, marketing expenditure, quality of product and after-sales service expenditures. The proposed model is formulated as a geometric programming with 5 degrees of difficulty and the problem is solved using the recent advances in optimization techniques. The study is supported by several numerical examples and sensitivity analysis is performed to analyze the effects of the changes in different parameters on the optimal solution. The preliminary results indicate that with the change in parameters influencing on demand, inventory holding, inventory deteriorating and set-up costs change and also significantly affect total revenue.

Physiological instability leading to clinical deterioration often precedes cardiopulmonary arrest. Nurses, who have the most frequent patient contact and responsibility for ongoing monitoring of patients, play a crucial role in recognizing and responding to clinical deterioration. The importance of education in supporting such a role has been addressed in numerous studies. This study aimed to identify nurses' educational needs and explore educational strategies to enhance their ability in recognizing and managing wards with deteriorating patients. A literature search from databases (2000-2010) was undertaken to include papers that identified the educational needs of ward nurses and existing educational programmes related to the care of deteriorating patients. Twenty-six papers were included in this review. Findings identified the educational need to empower nurses with the appropriate knowledge and skills in recognizing, reporting and responding to patient deterioration. The review of existing educational programmes and their outcomes identified valuable teaching information and strategies, and areas that could be improved in meeting nurses' educational needs. The review has highlighted important aspects of patient safety in clinical deterioration that could be further addressed by educational strategies targeting the role of ward nurses. These strategies include: utilizing clinical decision-making models to develop nurses' decision making skills; developing a standardized tool for systematic nursing assessment and management of clinical deterioration; incorporating training in clinical deterioration as a core competence of pre-registered nursing education; providing vital signs training to nursing assistants; and conducting more rigorous studies to evaluate the effectiveness of the educational programmes. © 2011 The Authors.

Four kinds of bioprotective alkaloids-peramine, loline, ergot alkaloid, indole-diterpenes, produced by grass-fungal endophyte symbioses, are deterrents or toxic to vertebrate and invertebrate herbivores. Ergot alkaloids have pharmacological properties and widely are used clinically. The regulation of alkaloids biosynthesis is under intensive study to improve the yield for better agricultural and medicinal application. In this paper, we summarize the structure, related genes, regulation, and toxicity of alkaloids. We focus on the biosynthesis and the regulation network of alkaloids.

Challenges Involved in the Development and Delivery of Abuse-deterrent Formulations of Opioid Analgesics.

Cohen, Joshua P; Mendoza, Mario; Roland, Carl

2018-02-01

This commentary examines the development, regulatory, and reimbursement challenges facing abuse-deterrent formulation (ADF) products. In January 2017, the Tufts Center for the Study of Drug Development convened a roundtable to explore clinical development, regulatory, and reimbursement challenges with respect to ADFs of opioid analgesics. Roundtable participants, who included a range of pharmaceutical industry and other experts, discussed multiple challenges. First, several key clinical development challenges were identified and discussed. These challenges pertain to prodrug development and development of deterrents against oral abuse. Second, experts suggested that more clarity is needed from regulatory authorities regarding standards for proving ADF labeling claims and for being rewarded with 3-year data exclusivity. Similarly, given the substantial burdens associated with the development of postapproval evidence generation, experts raised the need for a consistent regulatory policy related to postapproval evidence generation for all ADFs (branded and generic). Third, despite the public health benefits of certain ADF products, current coverage and access policies impede patient access. Payer justification for restrictive policies appears to be based more on budget impact considerations than cost-effectiveness. Fourth, there remains a need to further expand the evidence base regarding clinical and cost-effectiveness as well as abuse deterrence in a real-world setting for all ADF products. Clinical development challenges need to be overcome with respect to novel ADF technologies, such as prodrugs and deterrents against oral abuse. More clarity is needed from regulatory authorities on labeling claims and data exclusivity eligibility with respect to ADFs. Ensuring prescriber training and awareness of various options for treating pain, including ADF products, is an important step, as is educating payers about the public health benefits of ADFs in appropriate subpopulations of pain patients. In addition, physicians may need to incorporate appropriate risk stratification methods. Finally, it is important to establish a level playing field between coverage of ADF and non-ADF products so that non-ADF products are not given preferred formulary placement.

Lagerquist, Barbara; Winsor, Martha; Mate, Bruce

This study was conducted to determine whether a low-powered sound source could be effective at deterring gray whales from areas that may prove harmful to them. With increased interest in the development of marine renewal energy along the Oregon coast the concern that such development may pose a collision or entanglement risk for gray whales. A successful acoustic deterrent could act as a mitigation tool to prevent harm to whales from such risks. In this study, an acoustic device was moored on the seafloor in the pathway of migrating gray whales off Yaquina Head on the central Oregon coast. Shore-basedmore » observers tracked whales with a theodolite (surveyor’s tool) to accurately locate whales as they passed the headland. Individual locations of different whales/whale groups as well as tracklines of the same whale/whale groups were obtained and compared between times with the acoustic device was transmitting and when it was off. Observations were conducted on 51 d between January 1 and April 15, 2012. A total of 143 individual whale locations were collected for a total of 243 whales, as well as 57 tracklines for a total of 142 whales. Inclement weather and equipment problems resulted in very small sample sizes, especially during experimental periods, when the device was transmitting. Because of this, the results of this study were inconclusive. We feel that another season of field testing is warranted to successfully test the effectiveness of the deterrent, but recommend increasing the zone of influence to 3 km to ensure the collection of adequate sample sizes. Steps have been taken to acquire the necessary federal research permit modification to authorize the increased zone of influence and to modify the acoustic device for the increased power. With these changes we are confident we will be able to determine whether the deterrent is effective at deflecting gray whales. A successful deterrent device may serve as a valuable mitigation tool to protect gray whales, and other baleen whales, in the event that marine energy development poses a collision or entanglement risk.« less

An evaluation of Nova Scotia's alcohol ignition interlock program.

Alcohol ignition interlock programs for offenders aim to reduce recidivism among convicted drink drivers. This study presents an evaluation of Nova Scotia's interlock program implemented in 2008 in order to assess its effectiveness to reduce impaired driving and to help identify areas for improvement. Data used include conviction and crash records of individual participants; provincial monthly counts of alcohol-related charges, convictions and fatal and serious crashes; and interlock logged events. Methods used include descriptive statistics, survival analysis, time series and logistic regression analysis. With respect to specific deterrence (i.e., preventing recidivism) there was a 90% reduction in recidivism among voluntary participants since participation in the interlock program and a 79% reduction after these participants exited from the program. With respect to general deterrence (i.e., referring to a preventative effect on the entire population of drivers in Nova Scotia) there were temporary decreases in the numbers of alcohol-related charges (13.32%) and convictions (9.93%) and a small significant decrease in the number of fatal and serious injury alcohol-related crashes, following the implementation of the program. The evidence suggests the interlock program was better at preventing harm due to alcohol-impaired driving than the alternative of not using the interlock program. Recommendations were formulated supporting the continuation of the interlock program in Nova Scotia. Copyright © 2017 Elsevier Ltd. All rights reserved.

Dengue fever has spread worldwide and affects millions of people every year in tropical and subtropical regions of Africa, Asia, Europe and America. Since there is no effective vaccine against the dengue virus, prevention of disease transmission depends entirely on regulating the vector (Aedes aegypti) or interrupting human-vector contact. The aim of this study was to assess the oviposition deterrent activity of essential oils of three cultivars of torch ginger (Etlingera elatior, Zingiberaceae) against the dengue mosquito. Analysis of the oils by gas chromatography (GC)-mass spectrometry revealed the presence of 43 constituents, of which α-pinene, dodecanal and n-dodecanol were the major components in all cultivars. Solutions containing 100 ppm of the oils exhibited oviposition deterrent activities against gravid Ae. aegypti females. GC analysis with electroantennographic detection indicated that the oil constituents n-decanol, 2-undecanone, undecanal, dodecanal, trans-caryophyllene, (E)-β-farnesene, α-humulene, n-dodecanol, isodaucene and dodecanoic acid were able to trigger antennal depolarization in Ae. aegypti females. Bioassays confirmed that solutions containing 50 ppm of n-dodecanol or dodecanal exhibited oviposition deterrent activities, while a solution containing the alcohol and aldehyde in admixture at concentrations representative of the oil presented an activity similar to that of the 100 ppm oil solution. Docking and molecular dynamics simulations verified that the interaction energies of the long-chain oil components and Ae. aegypti odorant binding protein 1 were quite favorable, indicating that the protein is a possible oviposition deterrent receptor in the antenna of Ae. aegypti.

Testing and Contrasting Road Safety Education, Deterrence, and Social Capital Theories: A Sociological Approach to the Understanding of Male Drink-Driving in Chile's Metropolitan Region.

2011-01-01

Three theories offer different explanations to the understanding of male drink-driving. In order to test road safety education, deterrence, and social capital theories, logistic regression analysis was applied to predict respondents' statements of having or not having engaged in actual drink-driving (DD). Variable for road safety education theory was whether a driver had graduated from a professional driving school or not. Deterrence theory was operationalized with a variable of whether a driver had been issued a traffic ticket or not. Social capital theory was operationalized with two variables, having children or not and having religion identification or not. Since both variables 'years of formal education' and 'years of driving experience' have been reported to be correlated to alcohol consumption and DD respectively, these were introduced as controls. In order to assess the significance of each variable statistically, Wald tests were applied in seven models. Results indicate on the one hand that road safety education variable is not statistically significant; and on the other, deterrence theory variable and social capital theory variable 'having children' were both statistically significant at the level of .01. Findings are discussed in reference to Chile's context. Data were taken from the "Road Users Attitudes and Behaviors towards Traffic Safety" survey from the National Commission of Road Safety of the Government of Chile (2005). The sample size was reported to be 2,118 (N of male drivers was 396). This survey was representative of Chile's Metropolitan Region road users' population.

Systematic review of the prevention incentives of insurance and regulatory mechanisms for occupational health and safety.

2007-04-01

The objective of this study was to determine the strength of evidence on the effectiveness of two policy levers-the experience rating of workers' compensation insurance and the enforcement of occupational health and safety regulation-in creating incentives for firms to focus on health and safety issues. An extensive systematic literature review was undertaken in an effort to capture both published and grey literature studies on the topic. Studies that met specific subject-matter and methods criteria underwent a quality assessment. A qualitative approach to evidence synthesis, known as "best-evidence" synthesis, was used. This method ranks the strength of evidence on a particular topic on the basis of the number, quality, and consistency of studies on the topic. There was moderate evidence that the degree of experience rating reduces injuries, limited to mixed evidence that inspections offer general and specific deterrence and that citations and penalties aid general deterrence, and strong evidence that actual citations and penalties reduce injuries. Although experience rating is a key policy lever of those providing workers' compensation insurance, there is much to be learned about its merits. Few studies have concerned the topic, and most have used crude proxy measures or exploited natural experiments. There have been many more studies on the merits of regulation enforcement, even though here too measures were often crude. Nonetheless, this synthesis indicates that general deterrence is less effective in reducing injury incidence and severity, whereas specific deterrence with regard to citations and penalties does indeed have an impact.

Evaluating the abuse potential of opioids and abuse-deterrent -opioid formulations: A review of clinical study methodology.

Setnik, Beatrice; Schoedel, Kerri A; Levy-Cooperman, Naama; Shram, Megan; Pixton, Glenn C; Roland, Carl L

With the development of opioid abuse-deterrent formulations (ADFs), there is a need to conduct well-designed human abuse potential studies to evaluate the effectiveness of their deterrent properties. Although these types of studies have been conducted for many years, largely to evaluate inherent abuse potential of a molecule and inform drug scheduling, methodological approaches have varied across studies. The focus of this review is to describe current "best practices" and methodological adaptations required to assess abuse-deterrent opioid formulations for regulatory submissions. A literature search was conducted in PubMed® to review methodological approaches (study conduct and analysis) used in opioid human abuse potential studies. Search terms included a combination of "opioid," "opiate," "abuse potential," "abuse liability," "liking," AND "pharmacodynamic," and only studies that evaluated single doses of opioids in healthy, nondependent individuals with or without prior opioid experience were included. Seventy-one human abuse potential studies meeting the prespecified criteria were identified, of which 21 studies evaluated a purported opioid ADF. Based on these studies, key methodological considerations were reviewed and summarized according to participant demographics, study prequalification, comparator and dose selection, route of administration and drug manipulation, study blinding, outcome measures and training, safety, and statistical analyses. The authors recommend careful consideration of key elements (eg, a standardized definition of a "nondependent recreational user"), as applicable, and offer key principles and "best practices" when conducting human abuse potential studies for opioid ADFs. Careful selection of appropriate study conditions is dependent on the type of ADF technology being evaluated.

Rats and seabirds: effects of egg size on predation risk and the potential of conditioned taste aversion as a mitigation method.

PubMed

Latorre, Lucía; Larrinaga, Asier R; Santamaría, Luis

2013-01-01

Seabirds nesting on islands are threatened by invasive rodents, such as mice and rats, which may attack eggs, chicks and even adults. The low feasibility of rat eradications on many islands makes the development of alternate control plans necessary. We used a combination of field experiments on a Mediterranean island invaded by black rats (Rattusrattus) to evaluate (1) the predation risk posed to different-sized seabird eggs and (2), the potential of two deterrent methods (electronic and chemical) to reduce its impact. Rats were able to consume eggs of all sizes (12 to 68 g), but survival increased 13 times from the smallest to the largest eggs (which also had more resistant eggshells). Extrapolation to seabird eggs suggests that the smallest species (Hydrobatespelagicus) suffer the most severe predation risk, but even the largest (Larusmichahellis) could suffer >60% mortality. Nest attack was not reduced by the deterrents. However, chemical deterrence (conditioned taste aversion by lithium chloride) slowed the increase in predation rate over time, which resulted in a three-fold increase in egg survival to predation as compared to both control and electronic deterrence. At the end of the experimental period, this effect was confirmed by a treatment swap, which showed that conferred protection remains at least 15 days after cessation of the treatment. Results indicate that small seabird species are likely to suffer severe rates of nest predation by rats and that conditioned taste aversion, but not electronic repellents, may represent a suitable method to protect colonies when eradication or control is not feasible or cost-effective.

The aims of this chapter are to 1) help biologists or field personnel recognize the signs that indicate a crime may have been committed, and 2) to give readers a basic understanding of how a wildlife crime scene is processed. This chapter is not intended to give readers the tools to investigate a crime scene alone, but will hopefully make them a valuable asset to law enforcement agents who respond to the scene. An effectively processed case, resulting in prosecution of a suspect, supports the law as a deterrent to future acts that could endanger the conservation of wildlife.

1981-01-01

The data presented examine the relationship between postlaryngectomy communication method, and the extent of total laryngectomy and the use of radiation therapy. The expectations of speech therapy providers were also examined. The author interviewed 60 laryngectomy patients who were six months to 3 1/2 years postsurgery. Surgeries were grouped into four categories and correlated with communication method. The relationship was statistically significant with the most apparent deterrent effect exhibited only for the most extreme surgical excisions. There was no relationship with the use of radiation therapy. In many cases speech therapy providers' expectations were not supported by the data.

Optimal pricing and marketing planning plays an essential role in production decisions on deteriorating items. This paper presents a mathematical model for a three-level supply chain, which includes one producer, one distributor and one retailer. The proposed study considers the production of a deteriorating item where demand is influenced by price, marketing expenditure, quality of product and after-sales service expenditures. The proposed model is formulated as a geometric programming with 5 degrees of difficulty and the problem is solved using the recent advances in optimization techniques. The study is supported by several numerical examples and sensitivity analysis is performed to analyze the effects of the changes in different parameters on the optimal solution. The preliminary results indicate that with the change in parameters influencing on demand, inventory holding, inventory deteriorating and set-up costs change and also significantly affect total revenue.

We recorded electrical responses from sensory cells associated with gustatory sensilla on the labella of female Anopheles quadrimaculatus Say to salt, sucrose, quinine (a feeding deterrent), and the insect repellent, N,N-diethyl-3-methylbenzamide (DEET). A salt-sensitive cell responded to increasing concentrations of sodium chloride. A second cell was activated by increasing sucrose concentrations, while quinine, DEET, or a mixture of quinine + DEET elicited spike activity from a third cell, an apparent bitter- or deterrent-sensitive cell. Both quinine and DEET suppressed activity of the sugar-sensitive cell; sucrose suppressed activity of the bitter- or deterrent-sensitive cell. These results demonstrate separate gustatory pathways for a feeding stimulant and aversive contact cues mediated through distinct sensory inputs on the labellum. This sensory appendage may serve as a useful target to disrupt feeding behavior in this and other anopheline species, which transmit diseases like malaria to human populations.

Can Nuclear Terrorists be Deterred?

NASA Astrophysics Data System (ADS)

Ferguson, Charles

2005-04-01

Conventional thinking since September 11, 2001, posits that nuclear-armed terrorists cannot be deterred. However, not all terrorist groups are alike. For instance, those that are strongly affiliated with a national territory or a constituency that can be held hostage are more likely to be self-deterred against using or even acquiring nuclear weapons. In contrast, international terrorist organizations, such as al Qaeda, or apocalyptic groups, such as Aum Shinrikyo, may welcome retaliatory nuclear strikes because they embrace martyrdom. Such groups may be immune to traditional deterrence, which threatens direct punishment against the group in question or against territory or people the terrorists' value. Although deterring these groups may appear hopeless, nuclear forensic techniques could provide the means to establish deterrence through other means. In particular, as long as the source of the nuclear weapon or fissile material could be identified, the United States could threaten a retaliatory response against a nation that did not provide adequate security for its nuclear weapons or weapons-usable fissile material. This type of deterrent threat could be used to compel the nation with lax security to improve its security to meet rigorous standards.

The New Era of Counterforce

NASA Astrophysics Data System (ADS)

Lieber, Keir

Nuclear deterrence rests on the survivability of nuclear arsenals. For much of the nuclear age, counterforce disarming attacks those aimed at eliminating nuclear forces were nearly impossible because of the ability of potential victims to hide and protect their weapons. However, technological developments are eroding this foundation of nuclear deterrence. Advances rooted in the computer revolution have made nuclear forces around the world far more vulnerable than before. Specifically, two key approaches that countries have relied on to ensure arsenal survivability since the dawn of the nuclear age hardening and concealment have been undercut by leaps in weapons accuracy and a revolution in remote sensing. Various models, methods, and evidence demonstrate the emergence of new possibilities for counterforce disarming strikes. In short, the task of securing nuclear arsenals against attack is a far greater challenge than it was in the past. The new era of counterforce challenges the basis for confidence in contemporary deterrence stability, raises critical issues for national and international security policy, and sheds light on one of the enduring theoretical puzzles of the nuclear era: why international security competition has endured in the shadow of the nuclear revolution.

United States initiative for chemical weapons arms control. Master`s thesis, 2 August 1995-7 June 1996

This research investigates the US policy initiative renouncing the employment of chemical weapons (CW). The focus of the research is to determine if such an initiative will achieve the national objective for implementation of the Chemical Weapons Convention (CWC). If the initiative does not meet the national objective are there feasible options for the United States Government (USG). In 1993, the USG established a policy banning the use of chemical weapons. This act may have won the battle for the moral high ground, but it will not deter nor eliminate the use of chemical weapons worldwide. The relative ease bymore » which a nation can take various combinations of chemical compounds and produce a lethal chemical agent makes deterrence and/or complete elimination virtually impossible. The US should continue to employ the elements of diplomatic, informational, military, and economic policy regarding nonproliferation inclusive of a proven deterrent-CW. No use of CW or any weapon of mass destruction is best, but until the CWC is ratified a deterrent should be maintained by the US.« less

On sanction-goal justifications: How and why deterrence justifications undermine rule compliance.

PubMed

Mooijman, Marlon; van Dijk, Wilco W; van Dijk, Eric; Ellemers, Naomi

2017-04-01

Authorities frequently justify their sanctions as attempts to deter people from rule breaking. Although providing a sanction justification seems appealing and harmless, we propose that a deterrence justification decreases the extent to which sanctions are effective in promoting rule compliance. We develop a theoretical model that specifies how and why this occurs. Consistent with our model, 5 experiments demonstrated that-compared with sanctions provided without a justification or sanctions provided with a just-deserts justification-sanction effectiveness decreased when sanctions were justified as attempts to deter people from rule breaking. This effect was mediated by people feeling distrusted by the authority. We further demonstrated that (a) the degree to which deterrence fostered distrust was attenuated when the sanction was targeted at others (instead of the participant) and (b) the degree to which distrust undermined rule compliance was attenuated when the authority was perceived as legitimate. We discuss the practical implications for authorities tasked with promoting rule compliance, and the theoretical implications for the literature on sanctions, distrust, and rule compliance.

Denervation of the hind limb is a technique used to study peripheral nerve regeneration. Autotomy or autophagia is an undesirable response to denervation in such studies. Application of a commercially available lotion used to deter nail biting in humans reduced autotomy in rats after denervation but did not completely prevent it. In this study, this authors evaluated the application of picric acid to prevent autotomy in rats in peripheral nerve experiments. They carried out sciatic nerve transection in 41 adult female Wistar rats and then applied either bite-deterrent lotion (n = 26) or saturated picric acid solution (n = 15) topically to the affected hind limb immediately after surgery and every day for 1 month. Autotomy scores were lower for rats treated with picric acid than for rats treated with bite-deterrent lotion 1 week and 2 weeks after surgery but were not different between the two groups 4 weeks after surgery. The authors conclude that application of picric acid could be used as an alternative strategy to prevent autotomy in peripheral nerve studies.

This qualitative study explores corporations' motivations to comply with new natural health products (NHP) Regulations in Canada. Interviews were conducted with representatives from 20 Canadian NHP companies. Findings show that the rationale for compliance differs for large compared to small and medium-sized enterprises (SMEs). Large firms are motivated to comply with the regulations because of the deterrent fear of negative media coverage, social motivations, ability to comply and maintaining a competitive market advantage. In contrast, SMEs are motivated to comply due to the deterrent fear of legal prosecution and a sense of duty. PMID:17549245

Xanthohumol, a prenylated flavonoid from hops, and a supercritical carbon dioxide extract of spent hops were studied for their antifeedant activity against stored product insect pests: Sitophilus granarius L., Tribolium confusum Duv. and Trogoderma granarium Everts. Xanthohumol exhibited medium deterrent activity against the adults of S. granarius L. and larvae of T. confusum Duv. The spent hops extract was more active than xanthohumol towards the adults of T. confusum Duv. The potential application of the crude spent hops extract as a feeding deterrent against the stored product pests is proposed.

Remixing the ‘Appropriate Mix’: Reassessing NATO’s Deterrence and Defense Posture in the Face of New Threats

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

Juarez, Anthony

The North Atlantic Treaty Organization (NATO) and the countries of Europe face a renewed challenge from the east vis-à-vis the Putin regime in Moscow. In the face of these new challenges, NATO must reconsider its deterrence and defense posture in order to deter conflict in Europe. Unfortunately, Russian attempts to rewrite the rules of the post-Cold War international order by force have been coupled with nuclear saber rattling and overt nuclear threats. Russia’s nuclear threats, in addition to provocative changes to Russia’s nuclear posture in its Military Doctrine, are methods to make up for Russia’s conventional military inferiority relative tomore » NATO and the United States. Some have described Moscow’s actions as laying the groundwork for a nuclear coercion strategy. While the decrease in the nuclear arsenals of Russia and the United States has reduced the likelihood of nuclear annihilation to an all-time low since the height of the Cold War, Russia’s nuclear coercion strategy is increasing the probability of nuclear employment in Europe. The probability of nuclear use is compounded by Russia’s tremendous local military advantage around its periphery in spite of U.S. global military primacy. This military advantage increases the incentive to use military force if Russian decision-makers conclude that a quick military victory is possible, or if Russian leaders miscalculate based on an incorrect assessment of military force balance or resolve of their adversary. The integration of Lithuania, Latvia, and Estonia (referred to as the Baltics in this paper) into the NATO alliance in 2004 makes Russia’s military advantage in its periphery increasingly relevant. Each NATO state is required to assist any NATO state that comes under attack per Article V of the North Atlantic Treaty. The Baltic states’ proximity to Russia, their weak indigenous militaries, their former status as Soviet Republics, large population of ethnic Russians, and Russian President Vladimir V. Putin’s claim that he will protect Russians wherever they are makes the Baltics the most likely flashpoint for conflict between NATO and Russia. This analysis will tackle the problem of reshaping NATO’s deterrence and defense posture in light of the new Russian threat and its obligation to defend its most vulnerable members. Specifically, it will assess the suitability of NATO’s “appropriate mix” of nuclear, conventional, and missile defense capabilities to deterring conventional conflict with Russia and, if conventional deterrence fails, preventing Russian nuclear escalation. It will use a scenario-based approach informed by a deterrence model to explore how changes to NATO’s posture and policy could impact the deterrence of Russian aggression.« less

More depressive symptoms and low emotional support have been related to worse body composition. Body composition significantly deteriorates in aging men. Therefore, we aimed to examine whether high emotional support and low depressive symptoms are associated with better body composition and a decelerated age-related deterioration of body composition in aging men. A cross-sectional analysis including 269 self-reporting healthy men aged between 40 and 75 years living in the German-speaking part of Switzerland was conducted. Participants completed questionnaires on emotional support and depressive symptoms. The depression screening instrument was used to form a group with low (N = 225) and moderate (N = 44) depressive symptoms. Body mass index (BMI) and waist-to-hip ratio (WHR) were measured, and cell proportion (CP), fat mass (FM), and water balance (WB) were obtained using bioelectrical impedance analysis. Age-related associations emerged for WHR, CP, FM, and WB, but not for BMI. Emotional support was negatively associated with BMI, WHR, and WB, and only trend-wise with CP and FM. Group comparisons revealed that more depressive symptoms were associated with lower levels of CP and higher levels of WB. Both emotional support and depressive symptoms were significant moderators of the association between age and specific measures of body composition such as CP, FM, and WB. However, after correction for multiple testing for moderation analyses only the moderation effects of depressive symptoms on the association between age and WB and CP remained significant. Low depressive symptoms were associated with a better body composition as well as a decelerated decline in body composition and the role of emotional support acting as a buffer against age-related deterioration of body composition merits further investigation.

Swegle, J.; Tincher, D.

This is the second of three papers (in addition to an introductory summary) aimed at providing a framework for evaluating future reductions or modifications of the U.S. nuclear force, first by considering previous instances in which nuclear-force capabilities were eliminated; second by looking forward into at least the foreseeable future at the features of global and regional deterrence (recognizing that new weapon systems currently projected will have expected lifetimes stretching beyond our ability to predict the future); and third by providing examples of past or possible undesirable outcomes in the shaping of the future nuclear force, as well as somemore » closing thoughts for the future. This paper begins with a discussion of the current nuclear force and the plans and procurement programs for the modernization of that force. Current weapon systems and warheads were conceived and built decades ago, and procurement programs have begun for the modernization or replacement of major elements of the nuclear force: the heavy bomber, the air-launched cruise missile, the ICBMs, and the ballistic-missile submarines. In addition, the Nuclear Weapons Council has approved a new framework for nuclear-warhead life extension not fully fleshed out yet that aims to reduce the current number of nuclear explosives from seven to five, the so-called 3+2 vision. This vision includes three interoperable warheads for both ICBMs and SLBMs (thus eliminating one backup weapon) and two warheads for aircraft delivery (one gravity bomb and one cruise-missile, eliminating a second backup gravity bomb). This paper also includes a discussion of the current and near-term nuclear-deterrence mission, both global and regional, and offers some observations on future of the strategic deterrence mission and the challenges of regional and extended nuclear deterrence.« less

Production, perceptions, and punishment: restrictive deterrence in the context of cannabis cultivation.

PubMed

Nguyen, Holly; Malm, Aili; Bouchard, Martin

2015-03-01

American authorities have invested extraordinary resources to keep up with the growth in cannabis cultivation, and state-level cannabis laws have been changing rapidly. Despite these changes, little research on the relationship between criminal justice sanctions and grower behaviours exist, in particular research that examines restrictive deterrence - the altering of an illegal behaviour as opposed to desisting from it completely. We examine restrictive deterrence in the context of cannabis cultivation by modelling the relationship between the threat of sanctions and the size of cultivation site and number of co-offenders. We use data from an anonymous web survey where participants were recruited through advertisements on websites related to cannabis use and cultivation. Negative binomial regression were used on 337 cases that contain valid data on size of cultivation site and 338 cases that contain valid data on the number of co-offenders. Our study found some evidence that the severity of state sanctions reduces the size of cultivation sites among growers who reside in the state. However, the number of contacts with the police had the opposite effect. In addition, we did not find a restrictive deterrent effect for the number of co-offenders, suggesting that different factors affect different decision points. Interestingly, objective skill and subjective skill had positive and independent effects on size of site. Results suggest that state-level sanctions have a structuring effect by restricting the size of cultivation sites but further increases in sanctions or enforcement are unlikely to deter more individuals from growing cannabis. In fact, there may be some potential dangers of increased enforcement on cannabis growers. Copyright © 2014 Elsevier B.V. All rights reserved.

Taking into account the improvement in insecticidal activity by the inclusion of fluorine in the hydrazone moiety, the authors synthesized new 4-fluorobenzoic acid hydrazides and 3-acetyl-2,5-disubstituted-2,3-dihydro-1,3,4-oxadiazoles, substituting a phenyl group or a heteroaryl ring carrying one or two atoms of F, Cl and Br, and investigated their biting deterrent and larvicidal activities against Aedes aegypti for the first time. The compound 3-acetyl-5-(4-fluorophenyl)-2-[4-(dimethylamino)phenyl]-2,3-dihydro-1,3,4-oxadiazole (17) produced the highest biting deterrent activity (BDI = 1.025) against Ae. Aegypti, followed by 4-fluorobenzoic acid [(phenyl)methylene] hydrazide (1). These activity results were similar to those of N,N-diethyl-meta-toluamide (DEET), which showed a proportion not biting of 0.8-0.92. When compounds 1 and 17 were tested on cloth worn on human volunteers, compound 1 was not repellent for some volunteers until present in excess of 500 nmol cm(-2) , while compound 17 was not repellent at the highest concentration tested (1685 nmol cm(-2) ). In the larvicidal screening bioassays, only compounds 10, 11, 12 and 17 showed 100% mortality at the highest screening dose of 100 ppm against Ae. aegypti larvae. Compounds 11 and 12 with LD50 values of 24.1 and 30.9 ppm showed significantly higher mortality than 10 (80.3 ppm) and 17 (58.7 ppm) at 24-h post-treatment. The insecticidal and biting deterrent activities were correlated with the presence of a halogen atom on the phenyl or heteroaryl substituent of the hydrazone moiety. © 2012 Society of Chemical Industry.

Strategic Missile Defense & Nuclear Deterrence

NASA Astrophysics Data System (ADS)

Grego, Laura

The United States has pursued defenses against nuclear-armed long-range ballistic missiles since at least the 1950s. At the same time, concerns that missile defenses could undermine nuclear deterrence and potentially spark an arms race led the United States and Soviet Union to negotiate limits on these systems. The 1972 Anti-Ballistic Missile Treaty constrained strategic missile defenses for thirty years. After abandoning the treaty in 2002, President George W. Bush began fielding the Ground-based Midcourse Defense (GMD) homeland missile defense system on an extremely aggressive schedule, nominally to respond to threats from North Korea and Iran. Today, nearly fifteen years after its initial deployment, the potential and the limits of this homeland missile defense are apparent. Its test record is poor and it has no demonstrated ability to stop an incoming missile under real-world conditions. No credible strategy is in place to solve the issue of discriminating countermeasures. Insufficient oversight has not only exacerbated the GMD system's problems, but has obscured their full extent, which could encourage politicians and military leaders to make decisions that actually increase the risk of a missile attack against the United States. These are not the only costs. Both Russia and China have repeatedly expressed concerns that U.S. missile defenses adversely affect their own strategic capabilities and interests, particularly taken in light of the substantial US nuclear forces. This in turn affects these countries' nuclear modernization priorities. This talk will provide a technical overview of the US strategic missile defense system, and how it relates to deterrence against non-peer adversaries as well as how it affects deterrence with Russia and China and the long-term prospects for nuclear reductions

The role of opacity and transparency in achieving strategic stability in South Asia.

Rajain, Arpit; Ashraf, Tariq Mahmud

According to international relations theory, deterrence can be used as a tool to achieve stability between potentially hostile nations. India and Pakistan's long history of periodic crises raises the question of how they can achieve deterrence stability. 'Transparency' describes the flow of information between parties and plays a key role in establishing a deterrence relationship. This paper studies the balance needed between opacity and transparency in nuclear topics for the maintenance of deterrence stability between India and Pakistan. States with nuclear weapons are postulated to implement transparency in four categories: potential, capability, intent, and resolve. The study applies these categoriesmore » to the nuclear components of the ongoing India-Pakistan Composite Dialogue Working Group for Peace and Security including CBMs. To focus our efforts, we defined four scenarios to characterize representative strategic/military/political conditions. The scenarios are combinations of these two sets of opposite poles: competition - cooperation; extremism - moderation (to be understood primarily in a religious/nationalistic sense). We describe each scenario in terms of select focal areas (nuclear doctrine, nuclear command and control, nuclear stockpile, nuclear delivery/defensive systems, and conventional force posture). The scenarios help frame the realm of possibilities, and have been described in terms of expected conditions for the focal areas. We then use the conditions in each scenario to prescribe a range of information-sharing actions that the two countries could take to increase stability. We also highlight the information that should not be shared. These actions can be political (e.g., declarations), procedural (e.g., advance notice of certain military activities), or technologically based (e.g., seismic monitoring of the nuclear test moratorium).« less

One hundred eighty-two patients enrolled and received ≥1 dose of study drug, 170 entered openlabel treatment, and 136 completed the study. Patients receiving hydrocodone ER in the 12-week, placebo-controlled study continued their previous dose unless adjustment was needed; those previously receiving placebo (n=78) underwent dose titration/adjustment to an analgesic dose (15-90 mg every 12 hours). Patients received 22 weeks of open-label treatment. adverse events (AEs). Maintenance of analgesia: worst pain intensity (WPI) and average pain intensity (API) at each study visit. Aberrant drug behavior: study drug loss and diversion. AEs were reported for 65/182 (36 percent) patients during dose titration/ adjustment and 88/170 (52 percent) during open-label treatment. No treatmentrelated serious AEs were reported. There were no clinically meaningful trends in other safety assessments, including physical examinations and pure tone audiometry. One patient receiving hydrocodone ER 30 mg twice daily experienced a severe AE of neurosensory deafness that was considered treatment related. Mean WPI and API remained steady throughout open-label treatment. Six (3 percent) patients reported medication loss, and 5 (3 percent) reported diversion. Abuse-deterrent hydrocodone ER was generally well tolerated in patients with chronic low back pain, maintained efficacy, and was associated with low rates of loss and diversion.

The Future of the U.S. Nuclear Weapons Program

NASA Astrophysics Data System (ADS)

Brooks, Linton F.

2007-03-01

This paper will examine our plans for the future of the U.S. nuclear weapons program including efforts to ``transform'' the stockpile and supporting infrastructure. We proceed from the premise that the United States will need a safe, secure, and reliable nuclear deterrent for the foreseeable future. Moreover, the Stockpile Stewardship Program is working. Today's stockpile---comprised of legacy warheads left over from the Cold War---is safe and reliable. That said, we see increased risk, absent nuclear testing, in assuring the long-term safety and reliability of our current stockpile. Nor is today's nuclear weapons complex sufficiently ``responsive'' to fixing technical problems in the stockpile, or to potential adverse geopolitical change. Our task is to work to ensure that the U.S. nuclear weapons enterprise, including the stockpile and supporting infrastructure, meets long-term national security needs. Our approach is to develop and field replacement warheads for the legacy stockpile---so-called Reliable Replacement Warheads (RRW)---as a means to transform both the nuclear stockpile and supporting infrastructure.

HIV infection duration, social support and the level of trauma symptoms in a sample of HIV-positive Polish individuals.

The aim of this study was to investigate the relationship between the average HIV infection duration and the level of quantitatively rated post-traumatic stress disorder (PTSD) symptoms and social support dimensions in a sample of 562 Polish HIV+ adults. Possible moderating effects of social support on the relationship between the average HIV infection duration and the level of PTSD symptoms were also analysed. The results of this study suggest that the average HIV infection duration may intensify PTSD symptoms and deteriorate the perceived availability of social support in HIV+ individuals. However, a positive relationship between HIV infection duration and the level of trauma symptoms was observed only in the group of HIV+ individuals with low perceived available social support, but not in the group of HIV-infected individuals with high perceived available social support. This research provided some new insight into the psychological and social aspects of living with HIV. In particular, our results suggest that although HIV infection duration may intensify trauma symptoms and deteriorate social support, perceived available social support may act as a buffer against HIV-related trauma symptoms.

The presence of an endophytic fungus, Acremonium coenophialum, in tall fescue (Festuca arundinacea) deterred aphid feeding by Rhopalosiphum padi and Schizaphis graminum. Both species of aphid were unable to survive when confined to endophyte-infected tall fescue plants. Feeding deterrents and toxic factors to R. padi and Oncopeltus fasciatus, large milkweed bug, were primarily associated with a methanol extract obtained when endophyte-infected tall fescue seed was serially extracted with hexane, ethyl acetate, and methanol. The concentrations of pyrrolizidine alkaloids were determined to be 30 to 100 times greater in the methanol extract than in the hexane and ethyl acetate extracts. PMID:16346751

There have been two main deterrents to the development of semiportable nuclear reactors. One is the high development costs; the other is the inability to satisfy with assurance the questions of operational safety. This report shows how a split-core, heat-pipe cooled reactor could conceptually eliminate these deterrents, and examines and summarizes recent work on split-core, heat-pipe reactors. A concept for a small reactor that could be developed at a comparatively low cost is presented. The concept would extend the technology of subcritical radioisotope thermoelectric generators using 238 PuO2 to the evolution of critical space power reactors using 239 PuO2.

Document fraud deterrent strategies: four case studies

NASA Astrophysics Data System (ADS)

Mercer, John W.

1998-04-01

This paper discusses the approaches taken to deter fraud committed against four documents: the machine-readable passport; the machine-readable visa; the Consular Report of Birth Abroad; and the Border Crossing Card. General approaches are discussed first, with an emphasis on the reasons for the document, the conditions of its use and the information systems required for it to function. A cost model of counterfeit deterrence is introduced. Specific approaches to each of the four documents are then discussed, in light of the issuance circumstances and criteria, the intent of the issuing authority, the applicable international standards and the level of protection and fraud resistance appropriate for the document.

Potential feeding deterrents found in hemlock woolly adelgid, Adelges tsugae

The nonnative hemlock woolly adelgid ( Adelges tsugae Annand, Hemiptera: Sternorrhyncha: Adelgidae) has been a significant mortality agent of eastern hemlock ( Tsuga canadensis Carriere) throughout a large portion of its geographic range. During a study investigating adelgid vigor in relation to host health, it was noted that adelgid extracts ranged from a yellow to a deep red color. Analysis by GC-MS identified the presence of the anthraquinone, chrysophanol and its anthrone precursor, chrysarobin in the extract. These compounds are predator deterrents in several other insects, including chrysomelid beetles. It is hypothesized that these compounds serve a similar purpose in the hemlock woolly adelgid.

Three gustatory receptor neurons were characterized for contact chemoreceptive sensilla on the labella of female yellow-fever mosquitoes, Aedes aegypti. The neuron with the smallest amplitude spike responded to the feeding deterrent, quinine, as well as N, N-diethyl-3-methylbenzamide and other insect repellents. Two other neurons with differing spikes responded to salt (NaCl) and sucrose. This is the first report of a gustatory receptor neuron specific for insect repellents in mosquitoes and may provide a tool for screening chemicals to discover novel or improved feeding deterrents and repellents for use in the management of arthropod disease vectors.

Mature leaves of the sweet pepper, Capsicum annuum, exhibited resistance against the American serpentine leafminer, Liriomyza trifolii (Burgess), Agromyzidae. Based on bioassay-guided fractionation, three compounds, namely 4-aminobutanoic acid, (2S,4R)-4-hydroxy-1-methyl-2-pyrrolidine carboxylic acid and 4-amino-1-beta-D-ribofuranosyl-2(1H)-pyrimidinone, were isolated from the leaves of sweet pepper. These compounds had significant oviposition deterrence towards adult flies of L. trifolii from laying their eggs on host plant leaves treated at 3.70, 16.60 and 6.45 microg/cm(2), respectively.

Assessing the Impact of a Focused Deterrence Strategy to Combat Intimate Partner Domestic Violence.

PubMed

Sechrist, Stacy M; Weil, John D

2018-03-01

The Offender Focused Domestic Violence Initiative (OFDVI) represents for the first time anywhere the application of the evidence-based focused deterrence policing approach to combat intimate partner domestic violence (IPDV). Through holding offenders accountable, the strategy has resulted in 20% reductions each in IPDV-related calls for police service and arrests. Victim injuries have been significantly reduced and the 1-year IPDV offender recidivism rate is about 16-17%. The backbone of the OFDVI strategy is the multidisciplinary collaboration of law enforcement and community partners which has resulted in identification and resolving system issues which have historically allowed offenders to repeat IPDV without consequence.

Association between alcoholism and the dopamine D4 receptor gene.

Muramatsu, T; Higuchi, S; Murayama, M; Matsushita, S; Hayashida, M

1996-01-01

A point mutation in the aldehyde dehydrogenase 2 gene (ALDH2(2) allele) is considered to be a genetic deterrent for alcoholism; however, 80 of 655 Japanese alcoholics had the mutant allele. Genotype factors that might increase susceptibility by overriding the deterrent showed a higher frequency of a five repeat allele of the dopamine D4 receptor 48 bp repeat polymorphism in alcoholics with ALDH2(2) than in 100 other alcoholics and 144 controls. Alcoholics with the five repeat allele also abused other drugs more often. These data suggest the involvement of the dopamine system in the development of alcoholism and other addictive behaviour.

Examining deterrence of adult sex crimes: A semi-parametric intervention time series approach.

PubMed

Park, Jin-Hong; Bandyopadhyay, Dipankar; Letourneau, Elizabeth

2014-01-01

Motivated by recent developments on dimension reduction (DR) techniques for time series data, the association of a general deterrent effect towards South Carolina (SC)'s registration and notification (SORN) policy for preventing sex crimes was examined. Using adult sex crime arrestee data from 1990 to 2005, the the idea of Central Mean Subspace (CMS) is extended to intervention time series analysis (CMS-ITS) to model the sequential intervention effects of 1995 (the year SC's SORN policy was initially implemented) and 1999 (the year the policy was revised to include online notification) on the time series spectrum. The CMS-ITS model estimation was achieved via kernel smoothing techniques, and compared to interrupted auto-regressive integrated time series (ARIMA) models. Simulation studies and application to the real data underscores our model's ability towards achieving parsimony, and to detect intervention effects not earlier determined via traditional ARIMA models. From a public health perspective, findings from this study draw attention to the potential general deterrent effects of SC's SORN policy. These findings are considered in light of the overall body of research on sex crime arrestee registration and notification policies, which remain controversial.

Malpractice litigation and nursing home quality of care.

2013-12-01

To assess the potential deterrent effect of nursing home litigation threat on nursing home quality. We use a panel dataset of litigation claims and Nursing Home Online Survey Certification and Reporting (OSCAR) data from 1995 to 2005 in six states: Florida, Illinois, Wisconsin, New Jersey, Missouri, and Delaware, for a total of 2,245 facilities. Claims data are from Westlaw's Adverse Filings database, a proprietary legal database, on all malpractice, negligence, and personal injury/wrongful death claims filed against nursing facilities. A lagged 2-year moving average of the county-level number of malpractice claims is used to represent the threat of litigation. We use facility fixed-effects models to examine the relationship between the threat of litigation and nursing home quality. We find significant increases in registered nurse-to-total staffing ratios in response to rising malpractice threat, and a reduction in pressure sores among highly staffed facilities. However, the magnitude of the deterrence effect is small. Deterrence in response to the threat of malpractice litigation is unlikely to lead to widespread improvements in nursing home quality. This should be weighed against other benefits and costs of litigation to assess the net benefit of tort reform. © Health Research and Educational Trust.

Insecticidal and Repellent Activity of Several Plant-Derived Essential Oils Against Aedes aegypti.

2017-03-01

We examined the pupicidal, adulticidal, repellent, and oviposition-deterrent activities of essential oils (EOs) from Lippia alba, L. origanoides, Eucalyptus citriodora, Cymbopogon citratus, Cymbopogon flexuosus, Citrus sinensis , Cananga odorata , Swinglea glutinosa, and Tagetes lucida plants against Aedes aegypti under laboratory conditions. Pupicidal and adulticidal activities were assessed at exploratory concentrations of 250, 310, and 390 parts per million (ppm); and 30, 300, and 1,000 ppm, respectively. The greatest pupicidal activity was exhibited at 390 ppm with a 24-h exposure by L. origanoides, and 390 ppm with a 48-h exposure by Citrus sinensis . Lippia origanoides killed all adult mosquitoes at 300 ppm after 120 min of exposure. Only L. origanoides and E. citriodora EOs, applied at 1,000 ppm to human skin, produced the greatest repellency (100%) to host-seeking Ae. aegypti after 2 min of exposure; the repellency decreased between 12% and 10% after 15 min. Complete oviposition deterrence by gravid Ae. aegypti was observed for E. citriodora EOs at 200 ppm with an oviposition activity index of -1.00. These results confirm that the EOs assessed in this study have insecticidal, repellent, and oviposition-deterrent activities against the dengue vector, Ae. aegypti.

Will abuse-deterrent formulations of opioid analgesics be successful in achieving their purpose?

PubMed

Bannwarth, Bernard

2012-09-10

During the last 2 decades, there has been a dramatic increase in the use of strong opioids for chronic non-cancer pain. This increase has been accompanied by a steep increase in abuse, misuse, and both fatal and non-fatal overdoses involving prescription opioids. The situation is already alarming in the US. Prescription opioid-related harm is a complex, multifactorial issue that requires a multifaceted solution. In this respect, formulations of opioid analgesics designed to resist or deter abuse may be a useful component of a comprehensive opioid risk minimization programme. Such formulations have or are being developed. Abuse-resistant opioids include those that use some kind of physical barrier to prevent tampering with the formulation. Abuse-deterrent opioids are not necessarily resistant to tampering, but contain substances that are designed to make the formulation less attractive to abusers. This article focuses on two products intended to deter abuse that were reviewed by the US Food and Drug Administration (FDA). The first (Embeda®) consists of extended-release morphine with sequestered naltrexone, an opioid antagonist that is released if the tablet is compromised by chewing or crushing. Although Embeda® exhibited abuse-deterrent features, its label warns that it can be abused in a manner similar to other opioid agonists. Furthermore, tampering with Embeda® will result in the release of naltrexone, which may precipitate withdrawal in opioid-tolerant individuals. In March 2011, all dosage forms of Embeda® were recalled because the product failed to meet routine stability standards, and its return date to the market is currently unknown. The second product (Acurox®) was intended to be both tamper resistant and abuse deterrent. It consisted of an immediate-release oxycodone tablet with subtherapeutic niacin as an aversive agent and used a gel-forming ingredient designed to inhibit inhalation and prevent extraction of the drug for injection. The new drug application for Acurox® was rejected in 2010 by the FDA because of concerns about the potential abuse-deterrent benefits of niacin. While acknowledging that no one formulation can be expected to deter all types of opioid-abusive behaviours and no product is likely to be abuse proof in the hands of clear and determined abusers, the reductions in abuse these new products would provide may be an incremental step towards safer prescription opioids.

Deterioration of organic packing materials commonly used in air biofiltration: effect of VOC-packing interactions.

PubMed

Lebrero, Raquel; Estrada, José M; Muñoz, Raúl; Quijano, Guillermo

2014-05-01

The abiotic deterioration of three conventional organic packing materials used in biofiltration (compost, wood bark and Macadamia nutshells) caused by their interaction with toluene (used as a model volatile organic compound) was here studied. The deterioration of the materials was evaluated in terms of structural damage, release of co-substrates and increase of the packing biodegradability. After 21 days of exposure to toluene, all packing materials released co-substrates able to support microbial growth, which were not released by the control materials not exposed to toluene. Likewise, the exposure to toluene increased the packing material biodegradability by 26% in wood bark, 20% in compost and 17% in Macadamia nutshells. Finally, scanning electron microscopy analysis confirmed the deterioration in the structure of the packing materials evaluated due to the exposure to toluene, Macadamia nutshells being the material with the highest resistance to volatile organic compound attack.

Study on the deterioration origin of thermomechanical contact fatigue

NASA Astrophysics Data System (ADS)

Tudose-Sandu-Ville, O. F.

2016-08-01

Thermomechanical wear is a complex phenomenon present in a number of industrial domains, such as rolling bearings, gears, friction wheels, rolling mill rollers. In this type of surface tribological deterioration, both fundamental and some peculiar wears are combined (abrasive, adhesive, corrosive wear and contact fatigue), with mechanical ant thermal causes. The present paper takes into account the contact fatigue type of deterioration, with both causes in mechanical variable load and the thermal tide action on the contact surface. There are some theories synthetically presented regarding the location of critical stresses in rolling contact fatigue. The Jacq thermal effect is briefly presented with some considerations concerning the temperature gradient in the metallic wall. The connection between the Jacq thermal anomaly and the thermomechanical contact fatigue is considered to be a new approach. Also, the same location for both mechanical and thermal critical stresses gives a strong support for the thermomechanical contact fatigue primary deterioration, according to the results obtained during the author's PhD research.

Enforcer, manager or leader? The judicial role in family violence courts.

PubMed

King, Michael; Batagol, Becky

2010-01-01

Judicial supervision of offenders is an important component of many family violence courts. Skepticism concerning the ability of offenders to reform and a desire to protect victims has led to some judges to use supervision as a form of deterrence. Supervision is also used to hold offenders accountable for following court orders. Some family violence courts apply processes used in drug courts, such as rewards and sanctions, to promote offender rehabilitation. This article suggests that while protection and support of victims should be the prime concern of family violence courts, a form of judging that engages offenders in the development and implementation of solutions for their problems and supports their implementation is more likely to promote their positive behavioral change than other approaches to judicial supervision. The approach to judging proposed in this article draws from therapeutic jurisprudence, feminist theory, transformational leadership and solution-focused brief therapy principles.

Secular trends in opioid prescribing in the USA.

PubMed

Pezalla, Edmund J; Rosen, David; Erensen, Jennifer G; Haddox, J David; Mayne, Tracy J

2017-01-01

Opioid abuse and misuse in the USA is a public health crisis. The use of prescription opioid analgesics increased substantially from 2002 through 2010, then plateaued and began to decrease in 2011. This study examined prescriptions of branded and generic immediate- and extended-release opioid analgesics from 1992 to 2016. This was juxtaposed against state and federal policies designed to decrease overutilization and abuse, as well as the launch of new opioid products, including opioids with abuse-deterrent properties (OADPs). The data indicate that these health policies, including the utilization and reimbursement of OADPs, have coincided with decreased opioid utilization. The hypothesis that OADPs will paradoxically increase opioid prescribing is not supported.

A review of recent advances in data analytics for post-operative patient deterioration detection.

PubMed

Petit, Clemence; Bezemer, Rick; Atallah, Louis

2018-06-01

Most deaths occurring due to a surgical intervention happen postoperatively rather than during surgery. The current standard of care in many hospitals cannot fully cope with detecting and addressing post-surgical deterioration in time. For millions of patients, this deterioration is left unnoticed, leading to increased mortality and morbidity. Postoperative deterioration detection currently relies on general scores that are not fully able to cater for the complex post-operative physiology of surgical patients. In the last decade however, advanced risk and warning scoring techniques have started to show encouraging results in terms of using the large amount of data available peri-operatively to improve postoperative deterioration detection. Relevant literature has been carefully surveyed to provide a summary of the most promising approaches as well as how they have been deployed in the perioperative domain. This work also aims to highlight the opportunities that lie in personalizing the models developed for patient deterioration for these particular post-surgical patients and make the output more actionable. The integration of pre- and intra-operative data, e.g. comorbidities, vitals, lab data, and information about the procedure performed, in post-operative early warning algorithms would lead to more contextualized, personalized, and adaptive patient modelling. This, combined with careful integration in the clinical workflow, would result in improved clinical decision support and better post-surgical care outcomes.

Report of the Defense Science Board task force on tritium production technology options. Final technical report

Welch, L.

1999-05-01

The long-standing national security policy of the US to maintain a robust nuclear deterrent continues to be supported by the Congress and the President. The President has stated that ``...the nuclear deterrent posture is one of the most visible and important examples of how US military capabilities can be used effectively to deter aggression and coercion. Nuclear weapons serve as a hedge against an uncertain future, a guarantee of our security commitments to allies, and a disincentive to those who would contemplate developing or otherwise acquiring their own nuclear weapons.`` US nuclear weapons designs require tritium, an isotope of hydrogen,more » which has not been produced in the US since 1988, when the last tritium production facility (the K-Reactor at the Savannah River Site) was shut down. This long period without tritium production in the US has been possible because arms control agreements reached in the early 1990s reduced the size of the US nuclear weapons stockpile and because the Department of Energy (DOE) met stockpile tritium requirements by recycling the tritium removed from dismantled nuclear weapons. However, since tritium decays at a rate of 5.5% each year, a dependable source of tritium is required to continue to sustain the US nuclear weapons stockpile to underwrite national security policy and to support arms control goals. The US does maintain a five-year reserve supply of tritium, but this reserve is to be used only in an emergency. Current guidance states the reserve must be restored to its original level within five years of being used. To sustain the START I level, tritium production needs to begin around 2005 at a production capacity of about 3.0 kg/ year. START II levels could be sustained with production of about 1.5 kg/year beginning around 2011.« less

Deterrence of device counterfeiting, cloning, and subversion by substitution using hardware fingerprinting

2014-09-30

Deterrence of device subversion by substitution may be achieved by including a cryptographic fingerprint unit within a computing device for authenticating a hardware platform of the computing device. The cryptographic fingerprint unit includes a physically unclonable function ("PUF") circuit disposed in or on the hardware platform. The PUF circuit is used to generate a PUF value. A key generator is coupled to generate a private key and a public key based on the PUF value while a decryptor is coupled to receive an authentication challenge posed to the computing device and encrypted with the public key and coupled to output a response to the authentication challenge decrypted with the private key.

This is a contribution to the Catholic debate over nuclear weapons, by an international relations scholar who teaches at a Catholic college. Dougherty is critical of the 1983 pastoral letter, arguing that it focuses too much on the dangers of nuclear war and the inadequacies of deterrence while giving insufficient attention to Soviet expansionism and the need for stable deterrence through a judicious mixture of military modernization and arms control. He is concerned by an increase in ''Catholic nuclear pacifism,'' fearing that the pastoral letter could become a theological rationalization for neo-isolationism in the United States.

Acoustical deterrence of Silver Carp (Hypophthalmichthys molitrix)

2015-01-01

The invasive Silver Carp (Hypophthalmichthys molitrix) dominate large regions of the Mississippi River drainage and continue to expand their range northward threatening the Laurentian Great Lakes. This study found that complex broadband sound (0–10 kHz) is effective in altering the behavior of Silver Carp with implications for deterrent barriers or potential control measures (e.g., herding fish into nets). The phonotaxic response of Silver Carp was investigated using controlled experiments in outdoor concrete ponds (10 × 4.9 × 1.2 m). Pure tones (500–2000 Hz) and complex sound (underwater field recordings of outboard motors) were broadcast using underwater speakers. Silver Carp always reacted to the complex sounds by exhibiting negative phonotaxis to the sound source and by alternating speaker location, Silver Carp could be directed consistently, up to 37 consecutive times, to opposite ends of the large outdoor pond. However, fish habituated quickly to pure tones, reacting to only approximately 5 % of these presentations and never showed more than two consecutive responses. Previous studies have demonstrated the success of sound barriers in preventing Silver Carp movement using pure tones and this research suggests that a complex sound stimulus would be an even more effective deterrent.

Waging modern war: An analysis of the moral literature on the nuclear arms debate

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

Palmer-Fernandez, G.F.

1992-01-01

The primary aim was to examine the dominant views on the subject of deterrence and the use of nuclear weapons, to compare them with each other, and to consider objections that have or might be made against them. A second, more controversial and substantive, aim was to show that nuclear weapons and war-fighting plans engender some disturbing moral dilemmas that call into question fundamental ways of thinking about morality and some of the common intuitions on the relation of intentions and actions. The author examines the moral literature, both religious and secular, on nuclear arms policy written between the earlymore » 1960s and the late 1980s. Three different schools of thought, or parties,' are identified. To establish the differences among these parties, the author shows the various ways in which judgments on the use of nuclear weapons and on deterrence are linked either by a prohibitive moral principle which draws a moral equivalence going from action to intention or by a factual assumption about the nature of nuclear weapons. He concludes with the suggestion that the dilemmas that arise in the moral evaluation of nuclear deterrence represent a profound and much wider problem in moral theory between the ideals of character and the moral claims of politics.« less

The objective of the present investigation was to understand the effects of excipients and curing process on the abuse deterrent properties (ADP) of Polyox™ based directly compressible abuse deterrent tablet formulations (ADFs). The excipients investigated were lactose (monohydrate or anhydrous), microcrystalline cellulose and hydroxypropyl methylcellulose. The ADPs studied were tablet crush resistance or hardness, particle size distribution following mechanical manipulation, drug extraction in water and alcohol, syringeability and injectability. Other non-ADPs such as surface morphology and tablet dissolution were also studied. It was found that presence of 50% or more of water soluble or swellable excipient in the ADF tablets significantly affected the tablet hardness, particle size distribution following mechanical manipulation and drug extraction while small amount (5%) of excipients had either minimal or no effect on ADPs of these tablets. Addition of high molecular weight HPMC (K 100M) affected syringeability and injectability of ADF. Curing process was found to affect ADPs (hardness, particle size distribution, drug extraction and syringeability and injectability) when compared with uncured tablet. In conclusion, addition of large amount of excipients, especially water soluble ones in Polyox™ based ADF tablets increase the risk of abuse by various routes of administration.

Wiesenfeld, Lesley; Abbey, Susan; Takahashi, Sue Glover; Abrahams, Caroline

2014-01-01

Objective To examine factors influencing the choice of psychiatry as a career between residency program application and ranking decision making. Methods: Using an online questionnaire, applicants to the largest Canadian psychiatry residency program were surveyed about the impact of various factors on their ultimate decision to enter psychiatry residency training. Results: Applicants reported that patient-related stigma was a motivator in considering psychiatry as a career, but that negative comments from colleagues, friends, and family about choosing psychiatry was a deterrent. Training program length, limited treatments, and insufficient clerkship exposure were noted as deterrents to choosing psychiatry, though future job prospects, the growing role of neuroscience, and diagnostic complexity positively influenced choosing psychiatry as a specialty. Research and elective time away opportunities were deemed relatively unimportant to ranking decisions, compared with more highly weighted factors, such as program flexibility, emphasis on psychotherapy, service– training balance, and training program location. Most applicants also reported continuing to fine tune ranking decisions between the application and ranking submission deadline. Conclusions: Stigma, exposure to psychiatry, diagnostic complexity, and an encouraging job market were highlighted as positive influences on the choice to enter psychiatry residency. Interview and information days represent opportunities for continued targeted recruitment activity for psychiatry residency programs. PMID:25161070

Thermonuclear peace, the tightrope of deterrence

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

Uscher, A.R.

This policy analysis focuses on the actions and approaches that will best reduce the chances of nuclear war in a MAD world, where mutual terror and mutual dependence will define our bipolar environment for the foreseeable future. The general approach to this broad and complex issue can be summarized as follows: since plans for conducting and preventing nuclear war are likely to be self-fulfilling prophecies, the US should strive for rational declaratory and deployment policies that reduce the chance of nuclear conflict while maintaining our national-security interests. Stability, probably the single most-important and unifying theme in nuclear deterrence, is visualizedmore » as a set of incentive structures that create no perceived advantages in escalating at any point along a hypothetical-force continuum. The key element in establishing and maintaining superpower stability is the inability to achieve adequate damage limitation through a preemptive first strike. The power and number of nuclear weapons compared to the fragility and limited number of priority targets seriously challenge the utility of most defensive measures. Successfully walking the tightrope of deterrence will require careful balancing of legitimate and competing values. This is a difficult task, but with a clear and realistic vision of the future, it is a feasible one.« less

Reexamining the frequency range of hearing in silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp

USGS Publications Warehouse

Vetter, Brooke J.; Brey, Marybeth; Meninger, Allen F.

2018-01-01

Silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp (collectively bigheaded carp) are invasive fish that threaten aquatic ecosystems in the upper Midwest United States and the Laurentian Great Lakes. Controlling bigheaded carp is a priority of fisheries managers and one area of focus involves developing acoustic deterrents to prevent upstream migration. For an acoustic deterrent to be effective however, the hearing ability of bigheaded carp must be characterized. A previous study showed that bigheaded carp detected sound up to 3 kHz but this range is narrower than what has been reported for other ostariophysans. Therefore, silver and bighead carp frequency detection was evaluated in response to 100 Hz to 9 kHz using auditory evoked potentials (AEPs). AEPs were recorded from 100 Hz to 5 kHz. The lowest thresholds were at 500 Hz for both species (silver carp threshold: 80.6 ± 3.29 dB re 1 μPa SPLrms, bighead carp threshold: 90.5 ± 5.75 dB re 1 μPa SPLrms; mean ± SD). These results provide fisheries managers with better insight on effective acoustic stimuli for deterrent systems, however, to fully determine bigheaded carp hearing abilities, these results need to be compared with behavioral assessments.

Air transport of patients with pneumothorax: is tube thoracostomy required before flight?

PubMed

Braude, Darren; Tutera, Dominic; Tawil, Issac; Pirkl, Gregory

2014-01-01

It is conventionally thought that patients with pneumothorax (PTX) require tube thoracostomy (TT) before air medical transport (AMT), especially in unpressurized rotor-wing (RW) aircraft, to prevent deterioration from expansion of the PTX or development of tension PTX. We hypothesize that patients with PTX transported without TT tolerate RW AMT without serious deterioration, as defined by hypotension, hypoxemia, respiratory distress, intubation, bag valve mask ventilation, needle thoracostomy (NT), or cardiac arrest during transport. We conducted a retrospective review of a case-series of trauma patients transported to a single Level 1 trauma center via RW with confirmed PTX and no TT. Using standardized abstraction forms, we reviewed charts for signs of deterioration. Those patients identified as having clinical deterioration were independently reviewed for the likelihood that the clinical deterioration was a direct consequence of PTX. During the study period, 66 patients with confirmed PTX underwent RW AMT with an average altitude gain of 1890 feet, an average barometric pressure 586-600 mmHg, and average flight duration of 28 minutes. All patients received oxygen therapy; 14/66 patients (21%) were supported with positive pressure ventilation. Eleven of 66 patients (17%) had NT placed before flight and 4/66 (6%) had NT placed during flight. Four of 66 patients (6% CI0.3-11.7) may have deteriorated during AMT as a result of PTX; all were successfully managed with NT. In this series, 6% of patients with PTX deteriorated as result of AMT without TT, yet all patients were managed successfully with NT. Routine placement of TT in patients with PTX before RW AMT may not be necessary. Further prospective evaluation is warranted. Copyright © 2014 Air Medical Journal Associates.

An experimental hut study to quantify the effect of DDT and airborne pyrethroids on entomological parameters of malaria transmission

PubMed Central

2014-01-01

Background Current malaria vector control programmes rely on insecticides with rapid contact toxicity. However, spatial repellents can also be applied to reduce man-vector contact, which might ultimately impact malaria transmission. The aim of this study was to quantify effects of airborne pyrethroids from coils and DDT used an indoor residual spray (IRS) on entomological parameters that influence malaria transmission. Methods The effect of Transfluthrin and Metofluthrin coils compared to DDT on house entry, exit and indoor feeding behaviour of Anopheles gambiae sensu lato were measured in experimental huts in the field and in the semi-field. Outcomes were deterrence - reduction in house entry of mosquitoes; irritancy or excito-repellency – induced premature exit of mosquitoes; blood feeding inhibition and effect on mosquito fecundity. Results Transfluthrin coils, Metofluthrin coils and DDT reduced human vector contact through deterrence by 38%, 30% and 8%, respectively and induced half of the mosquitoes to leave huts before feeding (56%, 55% and 48%, respectively). Almost all mosquitoes inside huts with Metofluthrin and Transfluthrin coils and more than three quarters of mosquitoes in the DDT hut did not feed, almost none laid eggs and 67%, 72% and 70% of all mosquitoes collected from Transfluthrin, Metofluthrin and DDT huts, respectively had died after 24 hours. Conclusion This study highlights that airborne pyrethroids and DDT affect a range of anopheline mosquito behaviours that are important parameters in malaria transmission, namely deterrence, irritancy/excito-repellency and blood-feeding inhibition. These effects are in addition to significant toxicity and reduced mosquito fecundity that affect mosquito densities and, therefore, provide community protection against diseases for both users and non-users. Airborne insecticides and freshly applied DDT had similar effects on deterrence, irritancy and feeding inhibition. Therefore, it is suggested that airborne pyrethroids, if delivered in suitable formats, may complement existing mainstream vector control tools. PMID:24693934

Pollen preservation and Quaternary environmental history in the southeastern United States

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

Delcourt, P.A.; Delcourt, H.R.

Reconstructions of Quaternary environmental history based upon modern pollen/vegetation/climate calibrations are more tenable if the factors responsible for variation in pollen assemblages are evaluated. Examination of the state of preservation of Quaternary palynomorphs provides quantitative data concerning the degree of information loss due to alteration of pollen assemblages by syndepositional and post-depositional deterioration. The percentage, concentration, and influx values for total indeterminable pollen are useful criteria in providing an objective and quantitative basis for evaluating the comparability of pollen spectra within and between sites. Supporting data concerning sediment particle-size distribution, organic matter content, and concentration, influx, and taxonomic composition ofmore » both determinable pollen and plant macrofossils aid in reconstructing past depositional environments. The potential is high for deterioration of pollen in sediments from the southeastern United States, although considerable variation is found in both kind and degree of deterioration between lacustrine and alluvial sites of different ages and in different latitudes. Modern analogs are a basis for late Quaternary environmental reconstructions when pollen deterioration has not significantly biased the information content of fossil pollen assemblages.« less

Over the last two decades, the reinforcement of security-related migration policies has resulted in the perception of the foreigner, and especially the irregular migrant, as a category outside the circle of legality. The rights of foreigners in host countries have deteriorated due to the connection made between immigration and criminality. Restrictions imposed upon irregular migrants' basic political and civil rights have been accompanied by major obstacles to their access to economic and social rights, including the right to health. The events of 9/11 further contributed to this trend, which contradicts the basic premises of the human rights paradigm. Recent policy developments and ongoing international cooperation implementing systematic interception and interdiction mechanisms have led to the securitization of migration. The preventive and deterrent measures reinforce the security paradigm. By contrast, various national and international actors have been successful in defending irregular migrants' rights. At the domestic level, the involvement of the judiciary and civil society enhances the rights-based approach to foreigners. The role of judges is vital in holding policy-makers accountable for respecting the high national standards of human rights protection. This article elaborates on the dichotomy between the state's legitimate interest to ensure national security, and its domestic and international obligations to protect human rights for all, including irregular migrants. It focuses on the changing relationship between migration and security, on the one hand, and between state and individual, on the other hand. It affirms the necessity to recognize the pre-eminence of fundamental rights upon security concerns.

The aim of this study was to examine the associations among mentoring relationship quality (i.e., relational and instrumental quality), racial discrimination and coping efficacy with racial discrimination. Three social support models were tested, including the stress buffering, support mobilization, and support deterioration models. Participants were 257 urban, low-income Latina/o high school students, who completed surveys in both 9th and 10th grades. While controlling for gender and coping efficacy with discrimination in 9th grade, results supported the social support deterioration model. Specifically, there was a significant indirect effect of racial discrimination in 9th grade on coping efficacy in 10th grade through instrumental mentoring quality. As racial discrimination increased, mentoring quality decreased and then coping efficacy decreased. We also found that more racial discrimination in 9th grade was significantly associated with lower coping efficacy in 10th grade, and higher instrumental mentoring quality in 9th grade was significantly associated with higher coping efficacy in 10th grade, while controlling for gender and coping efficacy in 9th grade. Implications and recommendations for future research are discussed. © Society for Community Research and Action 2017.

Modern telemonitoring systems identify a serious patient deterioration when it already occurred. It would be much more beneficial if the upcoming clinical deterioration were identified ahead of time even before a patient actually experiences it. The goal of this study was to assess artificial intelligence approaches which potentially can be used in telemonitoring systems for advance prediction of changes in disease severity before they actually occur. The study dataset was based on daily self-reports submitted by 26 adult asthma patients during home telemonitoring consisting of 7001 records. Two classification algorithms were employed for building predictive models: naïve Bayesian classifier and support vector machines. Using a 7-day window, a support vector machine was able to predict asthma exacerbation to occur on the day 8 with the accuracy of 0.80, sensitivity of 0.84 and specificity of 0.80. Our study showed that methods of artificial intelligence have significant potential in developing individualized decision support for chronic disease telemonitoring systems.

Bird-window collisions cause an estimated one billion bird deaths annually in the United States. Building characteristics and surrounding habitat affect collision frequency. Given the importance of collisions as an anthropogenic threat to birds, mitigation is essential. Patterned glass and UV-reflective films have been proven to prevent collisions. At Duke University’s West campus in Durham, North Carolina, we set out to identify the buildings and building characteristics associated with the highest frequencies of collisions in order to propose a mitigation strategy. We surveyed six buildings, stratified by size, and measured architectural characteristics and surrounding area variables. During 21 consecutive days in spring and fall 2014, and spring 2015, we conducted carcass surveys to document collisions. In addition, we also collected ad hoc collision data year-round and recorded the data using the app iNaturalist. Consistent with previous studies, we found a positive relationship between glass area and collisions. Fitzpatrick, the building with the most window area, caused the most collisions. Schwartz and the Perk, the two small buildings with small window areas, had the lowest collision frequencies. Penn, the only building with bird deterrent pattern, caused just two collisions, despite being almost completely made out of glass. Unlike many research projects, our data collection led to mitigation action. A resolution supported by the student government, including news stories in the local media, resulted in the application of a bird deterrent film to the building with the most collisions: Fitzpatrick. We present our collision data and mitigation result to inspire other researchers and organizations to prevent bird-window collisions. PMID:26855877

Factors deterring dentistry, medical, pharmacy, and social science undergraduates from pursuing nursing as a healthcare career: a cross-sectional study in an Asian university.

Globally more registered nurses need to be recruited to meet the needs of aging populations and increased co-morbidity. Nursing recruitment remains challenging when compared to other healthcare programs. Despite healthcare students having similar motivation in joining the healthcare industry, many did not consider nursing as a career choice. This study aims to identify the deterrents to choosing nursing among healthcare undergraduates by examining the differences in the factors influencing healthcare career choices and nursing as a career choice. A cross sectional study was conducted using a 35-parallel items instrument known as Healthcare Career Choice and Nursing Career Choice scale. Six hundred and four (n = 604) first year medical, pharmacy, dentistry and social science students from a university in Singapore completed the survey. Nursing as a career was perceived by healthcare students to be more likely influenced by prior healthcare exposure, the nature of the work, job prospects, and social influences. Lack of autonomous decision making, perceived lower ability to make diagnosis, having to attend to patients' hygiene needs, engendered stigma, and lack of parental support were identified as deterring factors to choosing nursing as a career. An understanding of the deterrents to choosing nursing as career allows policy makers and educational leaders to focus on recruitment strategies. These include providing more exposure to nurses' roles in early school years, helping young people to overcome the fear of providing personal hygiene care, promoting nurses' autonomous nursing practice, addressing gender stigma, and overcoming parental objection.

The development of clinical reasoning skills in recognising and responding to clinical deterioration is essential in pre-registration nursing education. Simulation has been increasingly used by educators to develop this skill. To develop and evaluate the psychometric properties of a Clinical Reasoning Evaluation Simulation Tool (CREST) for measuring clinical reasoning skills in recognising and responding to clinical deterioration in a simulated environment. A scale development with psychometric testing and mixed methods study. Nursing students and academic staff were recruited at a university. A three-phase prospective study was conducted. Phase 1 involved the development and content validation of the CREST; Phase 2 included the psychometric testing of the tool with 15 second-year and 15 third-year nursing students who undertook the simulation-based assessment; Phase 3 involved the usability testing of the tool with nine academic staff through a survey questionnaire and focus group discussion. A 10-item CREST was developed based on a model of clinical reasoning. A content validity of 0.93 was obtained from the validation of 15 international experts. The construct validity was supported as the third-year students demonstrated significantly higher (p<0.001) clinical reasoning scores than the second-year students. The concurrent validity was also supported with significant positive correlations between global rating scores and almost all subscale scores, and the total scores. The predictive validity was supported with an existing tool. The internal consistency was high with a Cronbach's alpha of 0.92. A high inter-rater reliability was demonstrated with an intraclass correlation coefficient of 0.88. The usability of the tool was rated positively by the nurse educators but the need to ease the scoring process was highlighted. A valid and reliable tool was developed to measure the effectiveness of simulation in developing clinical reasoning skills for recognising and responding to clinical deterioration. Copyright © 2017.

Around the world, governments are faced with spiralling health care expenditures. This raises the need for further insight in the determinants of these expenditures. Existing literature focuses primarily on income, ageing, health care financing and supply variables. This paper includes medical malpractice system characteristics as determinants of health spending in OECD countries. Estimates from our regression models suggest that no-fault schemes for medical injuries with decoupling of deterrence and compensation reduce health expenditures per capita by 0.11%. Furthermore, countries that introduced a no-fault system without decoupling of deterrence and compensation are found to have higher (+0.06%) health care spending.

2018-01-16

In the 1990s, the U.S. nuclear weapons program shifted emphasis from developing new designs to dismantling thousands of existing weapons and maintaining a much smaller enduring stockpile. The United States ceased underground nuclear testing, and the Department of Energy created the Stockpile Stewardship Program to maintain the safety, security, and reliability of the U.S. nuclear deterrent without full-scale testing. This video gives a behind the scenes look at a set of unique capabilities at Lawrence Livermore that are indispensable to the Stockpile Stewardship Program: high performance computing, the Superblock category II nuclear facility, the JASPER a two stage gas gun, the High Explosive Applications Facility (HEAF), the National Ignition Facility (NIF), and the Site 300 contained firing facility.

Early detection of patient deterioration and prevention of adverse events are key challenges to patient safety. This study investigated clinical staff perceptions of current monitoring practices and the planned introduction of continuous monitoring devices on general wards. Multi-method study comprising structured surveys, in-depth interviews and device trial with log book feedback. Two general wards in a large urban teaching hospital in Sydney, Australia. Respiratory and neurosurgery nursing staff and two doctors. Nurses were confident about their abilities to identify patients at risk of deterioration, using a combination of vital signs and visual assessment. There were concerns about the accuracy of current vital signs monitoring equipment and frequency of intermittent observation. Both the nurses and the doctors were enthusiastic about the prospect of continuous monitoring and perceived it would allow earlier identification of patient deterioration; provide reassurance to patients; and support interdisciplinary communication. There were also reservations about continuous monitoring, including potential decrease in bedside nurse-patient interactions; increase in inappropriate escalations of patient care; and discomfort to patients. While continuous monitoring devices were seen as a potentially positive tool to support the identification of patient deterioration, drawbacks, such as the potential for reduced patient contact, revealed key areas that will require close surveillance following the implementation of devices. Training and improved interdisciplinary communication were identified as key requisites for successful implementation. © The Author 2016.

To explore the recognition and assessment of resident deterioration in the nursing home setting. There is a dearth of research exploring how nurses and personal-care-assistants manage a deteriorating nursing home resident. Critical ethnography. Observation and semi-structured interviews with 66 participants (general medical practitioners, nurses, personal-care-assistants, residents and family members) in two Australian nursing homes. The study has been reported in accordance with the Consolidated Criteria for Reporting Qualitative Research guidelines. The value of nursing assessment is poorly recognised in the nursing home setting. A lack of clarity regarding the importance of nursing assessments associated with resident care has contributed to a decreasing presence of registered nurses and an increasing reliance on personal-care-assistants who had inadequate skills and knowledge to recognise signs of deterioration. Registered nurses experienced limited organisational support for autonomous decision-making and were often expected to undertake protocol-driven decisions that contributed to potentially avoidable hospital transfers. Nurses need to demonstrate the importance of assessment, in association with day-to-day resident care and demand standardised, regulated, educational preparation of an appropriate workforce who are competent in undertaking this role. Workforce structures that enhance familiarity between nursing home staff and residents could result in improved resident outcomes. The value of nursing assessment, in guiding decisions at the point of resident deterioration, warrants further consideration. © 2018 John Wiley & Sons Ltd.

Recent studies have shown the potential of acoustic deterrents against invasive silver carp (Hypophthalmichthys molitrix). This study examined the phonotaxic response of the bighead carp (H. nobilis) to pure tones (500–2000 Hz) and playbacks of broadband sound from an underwater recording of a 100 hp outboard motor (0.06–10 kHz) in an outdoor concrete pond (10 × 5 × 1.2 m) at the U.S. Geological Survey Upper Midwest Environmental Science Center in La Crosse, WI. The number of consecutive times the fish reacted to sound from alternating locations at each end of the pond was assessed. Bighead carp were relatively indifferent to the pure tones with median consecutive responses ranging from 0 to 2 reactions away from the sound source. However, fish consistently exhibited significantly (P < 0.001) greater negative phonotaxis to the broadband sound (outboard motor recording) with an overall median response of 20 consecutive reactions during the 10 min trials. In over 50% of broadband sound tests, carp were still reacting to the stimulus at the end of the trial, implying that fish were not habituating to the sound. This study suggests that broadband sound may be an effective deterrent to bighead carp and provides a basis for conducting studies with wild fish.

The question of what deters crime is of both theoretical and practical interest. The present paper focuses on what factors deter minor, non-violent crimes, i.e., dishonest actions that violate the law. Much research has been devoted to testing the effectiveness of legal sanctions on crime, while newer models also include social sanctions (judgment of friends or family) and internal sanctions (feelings of guilt). Existing research suggests that both internal sanctions and, to a lesser extent, legal sanctions deter crime, but it is unclear whether this pattern is unique to Western countries or robust across cultures. We administered a survey study to participants in China, Colombia, Germany, Portugal, and USA, five countries from distinct cultural regions of the world. Participants were asked to report the likelihood of engaging in seven dishonest and illegal actions, and were asked to indicate the probability and severity of consequences for legal, friend, family, and internal sanctions. Results indicated that across countries, internal sanctions had the strongest deterrent effects on crime. The deterrent effects of legal sanctions were weaker and varied across countries. Furthermore, the deterrent effects of legal sanctions were strongest when internal sanctions were lax. Unexpectedly, social sanctions were positively related to likelihood of engaging in crime. Taken together, these results suggest that the relative strengths of legal and internal sanctions are robust across cultures and dishonest actions.

The objective of the present study was to develop techniques for an abuse-deterrent (AD) platform utilizing hot melt extrusion (HME) process. Formulation optimization was accomplished by utilizing Box-Behnken design of experiments to determine the effect of the three formulation factors: PolyOx™ WSR301, Benecel™ K15M, and Carbopol 71G; each of which was studied at three levels on TR attributes of the produced melt extruded pellets. A response surface methodology was utilized to identify the optimized formulation. Lidocaine Hydrochloride was used as a model drug, and suitable formulation ingredients were employed as carrier matrices and processing aids. All of the formulations were evaluated for the TR attributes such as particle size post-milling, gelling, percentage of drug extraction in water and alcohol. All of the DOE formulations demonstrated sufficient hardness and elasticity, and could not be reduced into fine particles (<150µm), which is a desirable feature to prevent snorting. In addition, all of the formulations exhibited good gelling tendency in water with minimal extraction of drug in the aqueous medium. Moreover, Benecel™ K15M in combination with PolyOx™ WSR301 could be utilized to produce pellets with TR potential. HME has been demonstrated to be a viable technique with a potential to develop novel abuse-deterrent formulations. PMID:24433429

How Bees Deter Elephants: Beehive Trials with Forest Elephants (Loxodonta africana cyclotis) in Gabon.

2016-01-01

In Gabon, like elsewhere in Africa, crops are often sources of conflict between humans and wildlife. Wildlife damage to crops can drastically reduce income, amplifying poverty and creating a negative perception of wild animal conservation among rural people. In this context, crop-raiding animals like elephants quickly become "problem animals". To deter elephants from raiding crops beehives have been successfully employed in East Africa; however, this method has not yet been tested in Central Africa. We experimentally examined whether the presence of Apis mellifera adansonii, the African honey bee species present in Central Africa, deters forest elephants (Loxodonta Africana cyclotis) from feeding on fruit trees. We show for the first time that the effectiveness of beehives as deterrents of elephants is related to bee activity. Empty hives and those housing colonies of low bee activity do not deter elephants all the time; but beehives with high bee activity do. Although elephant disturbance of hives does not impede honey production, there is a tradeoff between deterrence and the quantity of honey produced. To best achieve the dual goals of deterring elephants and producing honey colonies must maintain an optimum activity level of 40 to 60 bee movements per minute. Thus, beehives colonized by Apis mellifera adansonii bees can be effective elephant deterrents, but people must actively manage hives to maintain bee colonies at the optimum activity level.

Variability in chemical defense across a shallow to mesophotic depth gradient in the Caribbean sponge Plakortis angulospiculatus

The transition between shallow and mesophotic coral reef communities in the tropics is characterized by a significant gradient in abiotic and biotic conditions that could result in potential trade-offs in energy allocation. The mesophotic reefs in the Bahamas and the Cayman Islands have a rich sponge fauna with significantly greater percent cover of sponges than in their respective shallow reef communities, but relatively low numbers of spongivores. Plakortis angulospiculatus, a common sponge species that spans the depth gradient from shallow to mesophotic reefs in the Caribbean, regenerates faster following predation and invests more energy in protein synthesis at mesophotic depths compared to shallow reef conspecifics. However, since P. angulospiculatus from mesophotic reefs typically contain lower concentrations of chemical feeding deterrents, they are not able to defend new tissue from predation as efficiently as conspecifics from shallow reefs. Nonetheless, following exposure to predators on shallow reefs, transplanted P. angulospiculatus from mesophotic depths developed chemical deterrence to predatory fishes. A survey of bioactive extracts indicated that a specific defensive metabolite, plakortide F, varied in concentration with depth, producing altered deterrence between shallow and mesophotic reef P. angulospiculatus. Different selective pressures in shallow and mesophotic habitats have resulted in phenotypic plasticity within this sponge species that is manifested in variable chemical defense and tissue regeneration at wound sites.

Transduction mechanism(s) of Na-saccharin in the blowfly Protophormia terraenovae: evidence for potassium and calcium conductance involvement.

The study on transduction mechanisms underlying bitter stimuli is a particularly intriguing challenge for taste researchers. The present study investigates, in the labellar chemosensilla of the blowfly Protophormia terraenovae, the transduction mechanism by which saccharin evokes the response of the "deterrent" cell, with particular attention to the contribution of K(+) and Ca(2+) current and the role of cyclic nucleotides, since second messengers modulate Ca(2+), Cl(-) and K(+) currents to different extents. As assessed by extracellular single-sensillum recordings, our results show that the addition of a Ca(2+) chelator such as EGTA or the Ca(2+) current blockers SK&F-96365, Mibefradil, Nifedipine and W-7 decrease the response of the "deterrent" cell to saccharin. A similar decreasing effect was also obtained following the addition of 4-aminopyridine, a K(+) current blocker. On the contrary, the membrane-permeable cyclic nucleotide 8-bromoguanosine 3',5'-cyclic monophosphate (8Br-cGMP) activates this cell and shows an additive effect when presented mixed with saccharin. Our results are consistent with the hypothesis that in the labellar chemosensilla of the blowfly both Ca(2+) and K(+) ions are involved in the transduction mechanism of the "deterrent" cell in response to saccharin. Our results also suggest a possible pathway common to saccharin and 8Br-cGMP.

Abuse-Deterrent Opioid Formulations: Pharmacokinetic and Pharmacodynamic Considerations.

PubMed

Walter, Carmen; Knothe, Claudia; Lötsch, Jörn

2016-07-01

Abuse-deterrent formulations (ADFs) are technologically sophisticated pharmaceutical formulations that impede manipulation and extraction of opioids and/or provoke unpleasant effects when they are taken in excessive quantity. This is implemented by creating physical barriers, inseparably combining the opioid with an opioid antagonist or adding aversive agents to the formulation. These pharmaceutical changes may potentially alter the pharmacokinetics and consequently the pharmacodynamics of the opioid. In this review, comparative evidence on pharmacokinetic differences between abuse-deterrent and classical formulations of the same opioids is summarized; furthermore, pharmacodynamic differences, with a focus on analgesia and abuse-related symptoms, are addressed. Most of the 12 studies comparing opioid pharmacokinetics have judged the physically intact ADF as being bioequivalent to the corresponding classical formulation. Pharmacokinetic differences have, however, been reported with physically manipulated ADFs and have ranged from moderate deviations from bioequivalence to complete changes in the pharmacokinetic profile (e.g. from a sustained-release formulation to a fast-release formulation). Pharmacodynamic effects were assessed in 14 comparative studies, which reported that intact ADFs usually provided clinically equivalent analgesia and clear advantages with respect to their addiction potential. However, withdrawal symptoms could be induced by the ADFs, although rarely and, in particular, when the ADFs had been physically altered. This evidence suggests that opioid ADFs are a working concept resulting in mostly minor pharmacokinetic and pharmacodynamic differences in comparison with classical formulations; however, they may deviate from this equivalence when physically altered.

Codling moth, Cydia pomonella (L.), is a cosmopolitan pest of apple, potentially causing severe damage to the fruit. Currently used methods of combating this insect do not warrant full success or are harmful to the environment. The use of plant-derived semiochemicals for manipulation with fruit-infesting behavior is one of the new avenues for controlling this pest. Here, we explore the potential of Ginkgo biloba and its synthetic metabolites for preventing apple feeding and infestation by neonate larvae of C. pomonella. Experiments with crude extracts indicated that deterrent constituents of ginkgo are present among alkylphenols, terpene trilactones, and flavonol glycosides. Further experiments with ginkgo synthetic metabolites of medical importance, ginkgolic acids, kaempferol, quercetin, isorhamnetin, ginkgolides, and bilobalide, indicated that three out of these chemicals have feeding deterrent properties. Ginkgolic acid 15:0 prevented fruit infestation at concentrations as low as 1 mg/mL, bilobalide had deterrent effects at 0.1 mg/mL and higher concentrations, and ginkgolide B at 10 mg/mL. On the other hand, kaempferol and quercetin promoted fruit infestation by codling moth neonates. Ginkgolic acids 13:0, 15:1, and 17:1, isorhamnetin, and ginkgolides A and C had no effects on fruit infestation-related behavior. Our research is the first report showing that ginkgo constituents influence fruit infestation behavior and have potential applications in fruit protection.

Chemical defense and chemical variation in some tropical Pacific species of Halimeda (Halimedaceae; Chlorophyta)

Paul, Valerie J.; van Alstyne, Kathryn L.

1988-03-01

Over a dozen species of the genus Halimeda have been chemically investigated and found to produce the diterpenoid metabolites halimedatrial (1) and halimedatetraacetate (2) in varying concentrations. These meabolites have been proposed to play a role in chemical defense against herbivores based on their chemical structures and their demonstrated biological activities in laboratory and aquarium assays. We examined and compared the feeding deterrent effects of these two compounds tovard herbivorous fishes in field experiments on Guam reefs. Halimedatrial is a more effective feeding deterrent than halimedatetraacetate. It is the major secondary metabolite in young Halimeda macroloba and in the newly produced segments of growing plants. The organic extracts from young plants and new segments were significantly more deterrent than extracts from mature plant tissue. Some populations of Halimeda growing in reef-slope habitats, where herbivory is intense, also have high concentrations of halimedatrial. We compared extracts between reef slope and reef flat collections of Halimeda opuntia on Guam and Pohnpei (= Ponape), and H. discoidea and H. macroloba on Guam. We found that halimedtrial was the major metabolite in reef-slope collections of H. opuntia from Pohnpei and Pago Bay, Guam, and that halimedatetraacetate was the major metabolite a non-reef slope populations. In the cases examined, chemical defenses were greatest in (1) plant parts and (2) populations that were at greatest risk to herbivores.

In the 1990s, the U.S. nuclear weapons program shifted emphasis from developing new designs to dismantling thousands of existing weapons and maintaining a much smaller enduring stockpile. The United States ceased underground nuclear testing, and the Department of Energy created the Stockpile Stewardship Program to maintain the safety, security, and reliability of the U.S. nuclear deterrent without full-scale testing.

Confidence in Nuclear Weapons as Numbers Decrease and Time Since Testing Increases

NASA Astrophysics Data System (ADS)

Adams, Marvin

2011-04-01

As numbers and types of nuclear weapons are reduced, the U.S. objective is to maintain a safe, secure and effective nuclear deterrent without nuclear-explosive testing. A host of issues combine to make this a challenge. An evolving threat environment may prompt changes to security systems. Aging of weapons has led to ``life extension programs'' that produce weapons that differ in some ways from the originals. Outdated and changing facilities pose difficulties for life-extension, surveillance, and dismantlement efforts. A variety of factors can make it a challenge to recruit, develop, and retain outstanding people with the skills and experience that are needed to form the foundation of a credible deterrent. These and other issues will be discussed in the framework of proposals to reduce and perhaps eliminate nuclear weapons.

Interactions between herbivorous insects and plants storing terpenoids are poorly understood. This study describes the ability of Chrysolina herbacea to use volatiles emitted by undamaged Mentha aquatica plants as attractants and the plant's response to herbivory, which involves the production of deterrent molecules. Emitted plant volatiles were analyzed by GC-MS. The insect's response to plant volatiles was tested by Y-tube olfactometer bioassays. Total RNA was extracted from control plants, mechanically damaged leaves, and leaves damaged by herbivores. The terpenoid quantitative gene expressions (qPCR) were then assayed. Upon herbivory, M. aquatica synthesizes and emits (+)-menthofuran, which acts as a deterrent to C. herbacea. Herbivory was found to up-regulate the expression of genes involved in terpenoid biosynthesis. The increased emission of (+)-menthofuran was correlated with the upregulation of (+)-menthofuran synthase. PMID:21408066

Nuclear Smuggling Detection and Deterrence FY 2016 Data Analysis Annual Report

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

Enders, Alexander L.; Harris, Tyrone C.; Pope, Thomas C.

The National Nuclear Security Administration’s Office of Nuclear Smuggling Detection and Deterrence (NSDD) has facilitated the installation of more than 3,500 radiation portal monitors (RPMs) at 606 sites in 56 countries worldwide. This collection of RPMs represents the world’s largest network of radiation detectors and provides one element in the defense-in-depth approach that supports the Global Nuclear Detection Architecture. These systems support NSDD’s mission to build partner country capability to deter, detect, and interdict the illicit transport of radiological and fissile material through strategic points of entry and exit at seaports, airports, and border crossings. NSDD works collaboratively with partnermore » countries and international organizations to optimize the operation of these RPMs. The large amount of data provided by NSDD partner countries highlights the close cooperation and partnerships NSDD has built with 56 countries around the world. Thirty-seven of these countries shared at least some RPM-related data with NSDD in fiscal year 2016. This significant level of data sharing is a key element that distinguishes the NSDD office as unique among nuclear nonproliferation programs and initiatives: NSDD can provide specific, objective, data-driven decisions and support for sustaining the radiation detection systems it helped deploy. This data analysis report summarizes and aggregates the RPM data provided to the NSDD office for analysis and review in fiscal year 2016. The data can be used to describe RPM performance and characterize the wide diversity of NSDD deployment sites. For example, NSDD deploys detector systems across sites with natural background radiation levels that can vary by a factor of approximately six from site to site. Some lanes have few occupancies, whereas others have approximately 8,000 occupancies per day and the different types of cargo that travel through a site can result in site-wide alarm rates that range from near 0% at some sites to above 3% at others. Based on the data received, the global average uptime for NSDD RPMs was above 96% for fiscal year 2016. NSDD takes all of these factors into account in making recommendations to partner countries on how to most effectively manage and maintain site operations. NSDD utilizes reports and other information products created by data analysts to efficiently allocate the resources needed to detect and ultimately interdict illicit nuclear and radiological material.« less

Local gas transport limitation attributed to the ionomer thin-film in the catalyst layer is a major deterrent to widespread commercialization of polymer-electrolyte fuel cells. So far functionality and limitations of these thin-films have been assumed identical in the anode and cathode. In this study, Nafion ionomer thin-films on platinum(Pt) support were exposed to H 2 and air as model schemes, mimicking anode and cathode catalyst layers. Findings indicate decreased swelling, increased densification of ionomer matrix, and increased humidity-induced aging rates in reducing environment, compared to oxidizing and inert environments. Observed phenomenon could be related to underlying Pt-gas interaction dictating Pt-ionomermore » behavior. Presented results could have significant implications about the disparate behavior of ionomer thin-film in anode and cathode catalyst layers.« less

Due to significantly increased U.S. military involvement in deterrent, observer, security, peacekeeping and combat roles around the world, the military expects significant future growth in the demand for deployable virtual reality trainers with networked simulation capability of the battle space visualization process. The use of HMD technology in simulated virtual environments has been initiated by the demand for more effective training tools. The AHMD overlays computer-generated data (symbology, synthetic imagery, enhanced imagery) augmented with actual and simulated visible environment. The AHMD can be used to support deployable reconfigurable training solutions as well as traditional simulation requirements, UAV augmented reality, air traffic control and Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) applications. This paper will describe the design improvements implemented for production of the AHMD System.

Consumer participation in early detection of the deteriorating patient and call activation to rapid response systems: a literature review.

PubMed

Vorwerk, Jane; King, Lindy

2016-01-01

This review investigated the impact of consumer participation in recognition of patient deterioration and response through call activation in rapid response systems. Nurses and doctors have taken the main role in recognition and response to patient deterioration through hospital rapid response systems. Yet patients and visitors (consumers) have appeared well placed to notice early signs of deterioration. In response, many hospitals have sought to partner health professionals with consumers in detection and response to early deterioration. However, to date, there have been no published research-based reviews to establish the impact of introducing consumer involvement into rapid response systems. A critical research-based review was undertaken. A comprehensive search of databases from 2006-2014 identified 11 studies. Critical appraisal of these studies was undertaken and thematic analysis of the findings revealed four major themes. Following implementation of the consumer activation programmes, the number of calls made by the consumers following detection of deterioration increased. Interestingly, the number of staff calls also increased. Importantly, mortality numbers were found to decrease in one major study following the introduction of consumer call activation. Consumer and staff knowledge and satisfaction with the new programmes indicated mixed results. Initial concerns of the staff over consumer involvement overwhelming the rapid response systems did not eventuate. Evaluation of successful consumer-activated programmes indicated the importance of: effective staff education and training; ongoing consumer education by nurses and clear educational materials. Findings indicated positive patient outcomes following introduction of consumer call activation programmes within rapid response systems. Effective consumer programmes included information that was readily accessible, easy-to-understand and available in a range of multimedia materials accompanied by the explanation and support of health professionals. Introduction of consumer-activated programmes within rapid response systems appears likely to improve outcomes for patients experiencing deterioration. © 2015 John Wiley & Sons Ltd.

The effectiveness of virtual simulation in improving student nurses' knowledge and performance during patient deterioration: A pre and post test design.

Preparing nursing students to perform competently in complex emergency situations, such as during rapid patient deterioration, is challenging. Students' active engagement in such scenarios cannot be ensured, due to the unexpected nature of such infrequent events. Many students may consequently not experience and integrate the management of patient deterioration into their knowledge and practical competency by the end of their studies, making them unprepared to manage such situations as practicing nurses. This study investigated the effectiveness of virtual simulation in improving performance during rapid patient deterioration. To investigate the effectiveness of virtual simulation in improving student nurses' knowledge and performance during rapid patient deterioration. A pre- and post-test design was used. Nursing students at a university in Malta were invited to participate in a virtual simulation program named FIRST 2 ACTWeb™, using their own computer devices. A total of 166 (response rate=50%) second and third year diploma and degree nursing students participated in the study. The simulation included three scenarios (Cardiac-Shock-Respiratory) portraying deteriorating patients. Performance feedback was provided at the end of each scenario. Students completed pre- and post-scenario knowledge tests and performance during each scenario was recorded automatically on a database. Findings showed a significant improvement in the students' post-scenario knowledge (z=-6.506, p<0.001). Highest mean performance scores were obtained in the last scenario (M=19.7, median: 20.0, s.d. 3.41) indicating a learning effect. Knowledge was not a predictor of students' performance in the scenarios. This study supports virtual simulation as an effective learning tool for pre-registration nursing students in different programs. Simulation improves both knowledge about and performance during patient deterioration. Virtual simulation of rare events should be a key component of undergraduate nurse education, to prepare students to manage complex situations as practicing nurses. Copyright © 2018 Elsevier Ltd.

This study examines clinical predictors of symptom deterioration (relapse/recurrence) at the completion of a clinical intervention trial of depressed, low-income, predominantly Hispanic diabetes patients who were randomized to socio-culturally adapted collaborative depression treatment or usual care and who no longer met clinically significant depression criteria at 12 months post-trial baseline. A sub-cohort of 193 diabetes patients with major depression symptoms at baseline, who were randomized to a 12-month collaborative care intervention (INT) (problem-solving therapy and/or pharmacotherapy, telephone symptom monitoring/relapse prevention, behavioral activation and patient navigation support) or enhanced usual care (EUC), and who did not meet major depression criteria at 12 months were subsequently observed over 18 to 24 months. Post-trial depression symptom deterioration was similar between INT (35.2%) and EUC (35.3%) groups. Among the combined groups, significant predictors of symptom deterioration were baseline history of previous depression and/or dysthymia (odds ratio [OR] = 2.66), 12-month PHQ-9 score (OR = 1.22), antidepressant treatment receipt during the initial 12-months (OR = 2.38), 12-month diabetes symptoms (OR = 2.27), and new ICD-9 medical diagnoses in the initial 12 months (OR = 1.11) (R2 = 27%; max-rescaled R2 = 37%; likelihood ratio test, χ2 = 59.79, df = 5, P < 0.0001). Among predominantly Hispanic diabetes patients in community safety net primary care clinics whose depression had improved over 1 year, more than one-third experienced symptom deterioration over the following year. A primary care management depression care protocol that includes ongoing depression symptom monitoring, antidepressant adherence, and diabetes and co-morbid illness monitoring plus depression medication adjustment and behavioral activation may reduce and/or effectively treat depression symptom deterioration.

To systematically summarize the literature on the course of pain in patients with knee osteoarthritis (OA), prognostic factors that predict deterioration of pain, the course of physical functioning, and prognostic factors that predict deterioration of physical functioning in persons with knee OA. A search was conducted in PubMed, CINAHL, Embase, Psych-INFO, and SPORTDiscus up to January 2014. A meta-analysis and a qualitative data synthesis were performed. Of the 58 studies included, 39 were of high quality. High heterogeneity across studies (I(2)  >90%) and within study populations (reflected by large SDs of change scores) was found. Therefore, the course of pain and physical functioning was interpreted to be indistinct. We found strong evidence for a number of prognostic factors predicting deterioration in pain (e.g., higher knee pain at baseline, bilateral knee symptoms, and depressive symptoms). We also found strong evidence for a number of prognostic factors predicting deterioration in physical functioning (e.g., worsening in radiographic OA, worsening of knee pain, lower knee extension muscle strength, lower walking speed, and higher comorbidity count). Because of high heterogeneity across studies and within study populations, no conclusions can be drawn with regard to the course of pain and physical functioning. These findings support current research efforts to define subgroups or phenotypes within knee OA populations. Strong evidence was found for knee characteristics, clinical factors, and psychosocial factors as prognostics of deterioration of pain and physical functioning. © 2016, American College of Rheumatology.

Homarine as a feeding deterrent in common shallow-water antarctic lamellarian gastropodMarseniopsis mollis: A rare example of chemical defense in a marine prosobranch.

The common bright yellow antarctic lamellarian gastropodMarseniopsis mollis was examined for the presence of defensive chemistry. Proton nuclear magnetic resonance (NMR) spectroscopy indicated that a major component of ethanolic extracts purified by reversed-phase column chromatography was homarine. Further high-performance liquid chromatography (HPLC) analysis of the mantle, foot, and viscera verified the presence of homarine in all body tissues at concentrations ranging from 6 to 24 mg/g dry tissue. A conspicuous macroinvertebrate predator of the shallow antarctic benthos, the sea starOdontaster validus, always rejected live individuals ofM. mollis, while readily feeding on pieces of fish tail muscle. Filter paper disks treated with shrimp elicited a broad range of feeding behaviors in the sea starO. validus (movement of disc to mouth, extrusion of cardiac stomach, humped feeding posture). Shrimp disks treated with homarine (0.4 and 4 mg/disk) were rejected byO. validus significantly more frequently than control disks treated with solvent carrier and shrimp or shrimp alone. The highest concentration of homarine tested not only caused feeding deterrence, but in several sea stars a flight response was noted. Homarine was not detected in the tunic of the antarctic ascidianCnemidocarpa verrucosa, a presumed primary prey ofM. mollis. Nonetheless, crude extracts of the epizooites that foul the tunic (primarily the bryozoans and hydroids) contain homarine, suggestingM. mollis may ingest and derive its chemistry from these organisms. This appears to be only the third example of chemical defense in a member of the Order Mesogastropoda. As the vestigial internalized shell ofM. mollis is considered a primitive condition, the findings of this study lend support to the hypothesis that chemical defense evolved prior to shell loss in shell-less gastropods.

Determinants of plasma donation: A review of the literature.

Beurel, A; Terrade, F; Lebaudy, J-P; Danic, B

2017-09-01

The major contribution of Human Sciences in the understanding of the whole blood donation behavior has been through the study of individuals' motivations and deterrents to donate. However, if whole blood donation has been very widely studied in the last sixty years, we still know very little about plasma donation in voluntary non-remunerated environments. Yet, the need for plasma-derived products has been strongly increasing for some years, and blood collection agencies have to adapt if they want to meet this demand. This article aims to review the main motivations and deterrents to whole blood donation, and to compare them with those that we already know concerning plasma donation. Current evidence shows similarities between both behaviors, but also differences that indicate a need for further research regarding plasma donation. Copyright © 2017. Published by Elsevier SAS.

Challenging Harry Almond's position that nuclear deterrence is workable, the author contends that there is no historical basis for believing that anticipation of the horrors of war will be an effective deterrent. He questions the belief that the nuclear balance of terror has maintained the peace for the past 40 years because an arms race is inherently unstable. The argument that the pursuit of national interests takes precedence over any limitation imposed by international law reflects a perception of international law that is comparable to the Third Reich. The bases for a legal evaluation of the status of nuclear weaponsmore » under international law come from express and implicit treaty provisions, international custom, general principles of international law, judicial decisions, resolutions at the United Nations, and the opinions of qualified jurists as well as military necessity.« less

Improve medical malpractice law by letting health care insurers take charge.

PubMed

Reinker, Kenneth S; Rosenberg, David

2011-01-01

This essay discusses unlimited insurance subrogation (UIS) as a means of improving the deterrence and compensation results of medical malpractice law. Under UIS, health care insureds could assign their entire potential medical malpractice claims to their first-party commercial and government insurers. UIS should improve deterrence by establishing first-party insurers as plaintiffs to confront liability insurers on the defense side, leading to more effective prosecution of meritorious claims and reducing meritless and unnecessary litigation. UIS should improve compensation outcomes by converting litigation cost- and risk- laden "tort insurance" into cheaper and enhanced first-party insurance. UIS also promises dynamic benefits through further reforms by contract between the first-party and liability insurers that would take charge of system. No UIS-related costs are apparent that would outweigh these benefits. © 2011 American Society of Law, Medicine & Ethics, Inc.

Elasmobranchs can detect minute electromagnetic fields, <1 nV cm(-1), using their ampullae of Lorenzini. Behavioural responses to electric fields have been investigated in various species, sometimes with the aim to develop shark deterrents to improve human safety. The present study tested the effects of the Shark Shield Freedom7™ electric deterrent on (1) the behaviour of 18 white sharks (Carcharodon carcharias) near a static bait, and (2) the rates of attacks on a towed seal decoy. In the first experiment, 116 trials using a static bait were performed at the Neptune Islands, South Australia. The proportion of baits taken during static bait trials was not affected by the electric field. The electric field, however, increased the time it took them to consume the bait, the number of interactions per approach, and decreased the proportion of interactions within two metres of the field source. The effect of the electric field was not uniform across all sharks. In the second experiment, 189 tows using a seal decoy were conducted near Seal Island, South Africa. No breaches and only two surface interactions were observed during the tows when the electric field was activated, compared with 16 breaches and 27 surface interactions without the electric field. The present study suggests that the behavioural response of white sharks and the level of risk reduction resulting from the electric field is contextually specific, and depends on the motivational state of sharks.

In the present study, structural modifications were performed on callicarpenal (1) in an effort to understand the functional groups necessary for maintaining and/or increasing its activity and to possibly lead to more effective insect control agents. All modifications in this study targeted the C(12) aldehyde or the C(3) alkene functionalities or combinations thereof. Mosquito biting deterrency appeared to be influenced most by C(3) alkene modification as evidenced by catalytic hydrogenation that resulted in a compound having significantly less effectiveness than 1 at a test amount of 25 nmol/cm2. Oxidation and/or reduction of the C(12) aldehyde did not diminish mosquito biting deterrency, but, at the same time, none of the modifications were more effective than 1 in deterring mosquito biting. Toxicities of synthesized compounds towards Ae. aegypti ranged from an LD50 value of 2.36 to 40.11 microg per mosquito. Similarly, LD95 values ranged from a low of 5.59 to a high of 104.9 microg.

To prevent donor loss and improve retention, it is important to understand the major deterrents to blood donation and to identify factors that can be effectively addressed by blood centers. A 30-item self-administered questionnaire was completed in 2003 by 1705 first-time and 2437 repeat US donors who had not donated in 2 to 3 years. Asian, Hispanic, black, and white first-time and repeat donors rated the importance of deterrents to donation in their decision to not return with a 1 to 5 scale. Categorical analysis of variance methods were used to compare the importance of deterrents between first-time and repeat donors of different race or ethnicity. Not having a convenient place to donate was most commonly cited as an important or very important reason for not returning by 32 to 42 percent of first-time and 26 to 43 percent of repeat respondents. Although bad treatment and poor staff skills were less of a barrier than convenience, they were more important for minority donors. Other factors such as physical side effects, foreign travel, or length of the process appeared less important. Inconvenience is a major barrier to donating, suggesting that mobile collections and increased hours of operation might help recapture lapsed donors. The finding that lapsed minority donors were more likely to give bad treatment and poor staff skills as important reasons to not donate is disconcerting in light of the changing donor demographics and increased efforts to recruit these donors.

The cuticular hydrocarbons of insects are species-specific and often function as semiochemicals. The activity of Tribolium brevicornis cuticular hydrocarbons as feeding deterrents that ostensibly function to prevent pupal cannibalism and predation was evaluated. The cuticular hydrocarbons of T. brevicornis pupae were characterized and flour disk bioassays conducted with individual and combined extract components incorporated into artificial diets on which Tribolium adults fed for six days. Feeding by T. brevicornis and T. castaneum on flour disks containing cuticular extracts of T. brevicornis pupae resulted in reduced consumption and weight loss relative to feeding on control flour disks. In both cases, feeding deterrence indices exceeded 80% suggesting that T. brevicornis cuticular hydrocarbons could function to deter cannibalism and predation of pupae by larvae and adult beetles. Sixteen different cuticular hydrocarbons were identified in T. brevicornis pupal extracts. Eight of the commercially available linear alkanes were tested individually in feeding trials with eight Tribolium species. One compound (C28) significantly reduced the amount of food consumed by three species compared to control disks, whereas the compounds C25, C26, and C27 elicited increased feeding in some species. Four other compounds had no effect on consumption for any species. When four hydrocarbon mixtures were tested for synergistic deterrence on T. brevicornis and T. castaneum, none significantly influenced consumption. Our results indicate that the cuticular chemistry of T. brevicornis pupae could serve to deter predation by conspecific and congeneric beetles. PMID:22224957

Elasmobranchs can detect minute electromagnetic fields, <1 nVcm–1, using their ampullae of Lorenzini. Behavioural responses to electric fields have been investigated in various species, sometimes with the aim to develop shark deterrents to improve human safety. The present study tested the effects of the Shark Shield Freedom7™ electric deterrent on (1) the behaviour of 18 white sharks (Carcharodon carcharias) near a static bait, and (2) the rates of attacks on a towed seal decoy. In the first experiment, 116 trials using a static bait were performed at the Neptune Islands, South Australia. The proportion of baits taken during static bait trials was not affected by the electric field. The electric field, however, increased the time it took them to consume the bait, the number of interactions per approach, and decreased the proportion of interactions within two metres of the field source. The effect of the electric field was not uniform across all sharks. In the second experiment, 189 tows using a seal decoy were conducted near Seal Island, South Africa. No breaches and only two surface interactions were observed during the tows when the electric field was activated, compared with 16 breaches and 27 surface interactions without the electric field. The present study suggests that the behavioural response of white sharks and the level of risk reduction resulting from the electric field is contextually specific, and depends on the motivational state of sharks.

Legislating Change? Responses to Criminalizing Female Genital Cutting in Senegal

PubMed Central

Shell-Duncan, Bettina; Hernlund, Ylva; Wander, Katherine; Moreau, Amadou

2014-01-01

Although the international community has recently promoted legislation as an important reform strategy for ending female genital cutting (FGC), there exist divergent views on its potential effects. Supporters argue that legal prohibition of FGC has a general deterrent effect, while others argue legislation can be perceived as coercive, and derail local efforts to end the practice. This study examines the range of responses observed in rural Senegal, where a 1999 anti-FGC law was imposed on communities in which the practice was being actively contested and targeted for elimination. Drawing on data from a mixed-methods study, we analyze responses in relation to two leading theories on social regulation, the law and economics and law and society paradigms, which make divergent predictions on the interplay between social norms and legal norms. Among supporters of FGC, legal norms ran counter to social norms, and did little to deter the practice, and in some instances incited reactance or drove the practice underground. Conversely, where FGC was being contested, legislation served to strengthen the stance of those contemplating or favoring abandonment. We conclude that legislation can complement other reform strategies by creating an “enabling environment” that supports those who have or wish to abandon FGC. PMID:24771947

Gait and balance deterioration over a 12-month period in multiple sclerosis patients with EDSS scores ≤ 3.0.

It is not currently known whether gait and balance measures are responsive to deterioration of motor function in multiple sclerosis (MS) patients with low EDSS scores (≤3.0). The aim of this study was to quantify MS-related gait and balance deterioration over a 12-month period. Thirty-eight participants with MS (33 female, mean age: 41.1 ± 8.3 years), mean time since diagnosis 2.2 ± 4.1 years, EDSS score ≤3.0 and without clinical evidence of gait deterioration, were recruited. Participants performed walking trials and Functional and Lateral Reach Tests. Kinematics of the ankle and knee, and electromyography of the tibialis anterior and medial gastrocnemius muscles were also measured. Three participants reported relapses with worsening EDSS scores and 4 non-relapsing participants had worse EDSS scores at 12 months. There were significant decreases in mean gait speed, stride length and balance scores, and a significant increase in double support. Marked changes in ankle kinematics, with decreased medial gastrocnemius activity were observed. Gait and balance performance of non-disabled RRMS participants may progressively decline, even in the absence of both acute clinical relapse and change in clinical status measured by the EDSS.

Trials, tricks and transparency: how disclosure rules affect clinical knowledge.

PubMed

Dahm, Matthias; González, Paula; Porteiro, Nicolás

2009-12-01

Scandals of selective reporting of clinical trial results by pharmaceutical firms have underlined the need for more transparency in clinical trials. We provide a theoretical framework which reproduces incentives for selective reporting and yields three key implications concerning regulation. First, a compulsory clinical trial registry complemented through a voluntary clinical trial results database can implement full transparency (the existence of all trials as well as their results is known). Second, full transparency comes at a price. It has a deterrence effect on the incentives to conduct clinical trials, as it reduces the firms' gains from trials. Third, in principle, a voluntary clinical trial results database without a compulsory registry is a superior regulatory tool; but we provide some qualified support for additional compulsory registries when medical decision-makers cannot anticipate correctly the drug companies' decisions whether to conduct trials.

Demographic, psychosocial, and contextual correlates of tobacco use in sexual minority women.

2011-04-01

Demographic, psychosocial, and contextual correlates of tobacco use among sexual minority women (SMW) were assessed using data from a larger lesbian, gay, bisexual, and transgender (LGBT) study. Of the 171 participants, 42% (n = 71) were smokers. However, 61% of smokers reported a recent quit attempt, and 39% were taking action toward or planning to quit. In multivariable logistic regression, lack of insurance, frequent attendance at LGBT bars, greater awareness of anti-smoking messages, and fewer perceived deterrents to smoking were associated with greater odds of smoking. Our findings provide additional support for elevated smoking rates among SMW and help to identify factors associated with smoking in this population. Awareness of prevention campaigns, recent quit attempts, and intention to quit were high, suggesting opportunities for smoking cessation. Copyright © 2011 Wiley Periodicals, Inc.

Deterrence and transmission as mechanisms ensuring reliability of gossip.

PubMed

Giardini, Francesca

2012-10-01

Spreading information about the members of one's group is one of the most universal human behaviors. Thanks to gossip, individuals can acquire the information about their peers without sustaining the burden of costly interactions with cheaters, but they can also create and revise social bonds. Gossip has also several positive functions at the group level, promoting cohesion and norm compliance. However, gossip can be unreliable, and can be used to damage others' reputation or to circulate false information, thus becoming detrimental to people involved and useless for the group. In this work, we propose a theoretical model in which reliability of gossip depends on the joint functioning of two distinct mechanisms. Thanks to the first, i.e., deterrence, individuals tend to avoid informational cheating because they fear punishment and the disruption of social bonds. On the other hand, transmission provides humans with the opportunity of reducing the consequences of cheating through a manipulation of the source of gossip.

Education in Anti-Doping: The Art of Self-Imposed Constraints.

PubMed

Loland, Sigmund

2017-01-01

The pillars of anti-doping are detection, deterrence, and prevention. Detection takes the form of testing for banned substances. Deterrence builds on testing and gathering evidence. Athletes who test positive are exposed to penalties. The main tool of prevention is education. Education takes many forms and can be implemented in many ways. This chapter addresses the nature and challenges of current anti-doping education. Firstly, general goals of education and their connection to sport are discussed. Secondly, three normative interpretations of sport are presented, and their implications for anti-doping education are examined. Instrumentalist interpretations and interpretations with emphasis on performance and enhancement challenge the anti-doping campaign. A human excellence interpretation is advocated in which anti-doping is considered a consistent and integral part of sport. Thirdly, future challenges for anti-doping education are reflected upon. © 2017 S. Karger AG, Basel.

Strategic command, control, communications, and intelligence.

PubMed

Zraket, C A

1984-06-22

Command, control, communications, and intelligence (C(3)l) for nuclear forces are essential elements in the deterrence of nuclear war. The present C(3)l) system has vulnerabilities associated with its reliability, survivability, and endurance under attack, thereby weakening deterrence by increasing the ambiguity in our capabilities. Development of a reliable and enduring C(3)l) system would reduce this ambiguity. Its reliable, positive control of nuclear forces would give the national leadership more time to assess situations, ensure discriminate retaliation, and improve our ability to manage crises in general. These capabilities could help to stop a war rapidly should one start. A reliable and enduring C(3)1) system will be needed for a long time to come, even if a freeze on strategic nuclear forces is accomplished or other arms control successes achieved. Indeed, C(3)l) may be the best source today of confidence-building measures to reduce tensions and the threat of nuclear catastrophe.

Recurrent issues in efforts to prevent homicidal youth violence in schools: expert opinions.

Dill, Karen E; Redding, Richard E; Smith, Peter K; Surette, Ray; Cornell, Dewey G

2011-01-01

Developmental research on social influences on adolescents can guide practices aimed to prevent homicidal youth violence. School shootings have repeatedly raised questions about the contributory role of bullying and entertainment violence, how news media publicity might produce copycat crimes, and whether stiffer criminal sanctions might have a deterrent effect. This article presents the thoughts and recommendations of a group of experts on these topics summarizing the current knowledge base. In brief, bullying reduction programs may be a useful early prevention effort. Television and video games with violent themes can encourage aggressive behavior, but these media can be used to teach more prosocial behavior as well. The potential copycat effects of highly publicized crimes might be diminished with more restrained reporting, although more research is needed. Finally, there is substantial evidence that increased criminal sanctions for youthful offenders have not had a deterrent effect. Copyright © 2011 Wiley Periodicals, Inc., A Wiley Company.

Baxter, Kate

2013-06-01

To increase understanding of disabled and chronically ill people's experiences of revisiting choices by considering events that prompted people to reconsider choices; what factors motivated them to act upon these events and what factors affected their experiences of revisiting choices. A sub-sample of 20 disabled and chronically ill people who took part in a qualitative, longitudinal study exploring choice-making in the context of changing circumstances. Each person was interviewed three times. Analysis focussed on choices that people had been prompted to revisit. Most choices were about health or social care and were revisited within a year due to: changes in health or social circumstances; poorer than expected outcomes; and external interventions. People were motivated to make changes by a desire to maintain independence and control, but perceived short-term costs of decision-making could act as a deterrent. Experiences of revisiting choices were affected by help from other people and emotional strength. Making and revisiting choices is complex; people need support to engage with the continual cycle of choice-making. People who instigate revisions of their own accord may be particularly vulnerable to lack of support.

On international fisheries agreements, entry deterrence, and ecological uncertainty.

PubMed

Ellefsen, Hans; Grønbæk, Lone; Ravn-Jonsen, Lars

2017-05-15

A prerequisite for an international fisheries agreement (IFA) to be stable is that parties expect the benefits from joining the agreement to exceed the benefits from free riding on the agreement, and parties only comply with the agreement as long as this is true. The agreement, therefore, implicitly builds on an expectation of the ecological condition of the natural resource. Game theoretical models often assume that all parties have the same (often perfect) information about the resource and that the exploitation is an equilibrium use of the stock. As stated by experts in natural science, the fish ecology still has many open questions, for example how to predict population dynamics, migration patterns, food availability, etc. In some cases, parties disagree about the state, abundance, and migration of a stock, which can reduce the possibilities of reaching an agreement for exploitation of the stock. This paper develops a model and applies it to the North-East Atlantic mackerel fishery, in order to analyze an IFA under different ecological scenarios, and also combines the model with the economic theory of entry deterrence. The model is used empirically to determine whether the parties with original access to the resource have an advantage when forming an agreement with a new party in having the ability to fish the stock down to a smaller size and thereby prevent another party from entering into the fishery. With a basis in entry deterrence, combined with lack of information, the paper illustrates the obstacles that have made an agreement for the North-East Atlantic mackerel so difficult to achieve.

Deterrence and nuclear strategy

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

Lodal, J.M.

1980-01-01

Mr. Lodal sees the social aspects of an effective deterrence policy as no less important than its technological aspects; further, programs and policies must be put in place that enhance social cohesion, that demonstrate the will to carry through on the strategy that we in the Western world subscribe to. It is the challenge of this political objective that most demands our attention. He feels that, if we are to remain secure, we must restore not only political cohesion to the Western alliance but a sensible political relationship between the United States and the Soviet Union as well. Such amore » relationship will of necessity provide for arms control. If we are able to maintain the arms control agreements reached to date, including the ABM treaty and SALT II, we will be a step ahead. It is to be hoped that the administration taking office in January of 1981 can restore order to our political relationships and avoid the necessity of a major defense program change such as the one suggested here. Unfortunately, the risk of this not happening is very real, according to Mr. Lodal. Therefore, the conceptualizing of concrete policies to improve our strategic nuclear posture becomes imperative. Adding limited defenses to our traditional doctrine is simply the best of a set of difficult choices. Such defenses would make our threatened use of battlefield nuclear weapons more credible, and they would restore a measure of extended deterrence; battlefield weapons could be used with the knowledge that only a massive Soviet attack would harm the US homeland. Thus, the defense would create a second firebreak in the ladder of escalation.« less

Managing medical emergencies in mental health settings using an interprofessional in-situ simulation training programme: A mixed methods evaluation study.

Lavelle, Mary; Attoe, Chris; Tritschler, Christina; Cross, Sean

2017-12-01

In the UK, people with severe mental illness die up to 20years earlier than the general population, prompting increased focus on physical health in mental illness. However, training for mental health inpatient staff to meet patients' physical health needs has not received the same attention, with physical health training often being reactive and lacking evidence of effectiveness. To evaluate an interprofessional, in situ, simulation training intervention for managing medical deterioration in mental health settings. Investigating the impact of training on: 1. Participants' knowledge, confidence, and attitudes towards managing medical deterioration; and 2. Incident reporting, as an objective index of incident management. Participants' perceptions of the impact on their practice were qualitatively explored. This evaluation employed a mixed-methods pre-post intervention design. Fifty-three healthcare professionals participated including: mental health nurses, psychiatrists, healthcare assistants, and activity co-ordinators from two busy psychiatric triage wards in South London, UK. The intervention comprised eight half-day sessions delivered weekly across two wards. Structured surveys assessed participants' knowledge, confidence, and attitudes towards medical deterioration pre and post training. Participants' experience of training was qualitatively captured through post-course surveys and focus groups three months post training. Incident reporting rates for seven-month periods pre and post training were compared. Following training, participants showed significant improvement in knowledge (p<0.001), confidence (p<0.001), and attitudes towards (p<0.02) managing medical deterioration. Incident reporting increased by 33% following training. Participants' reported improved confidence in managing medical deterioration, better understanding of effective communication, improved self-reflection and team working, and an increased sense of responsibility for patients' physical health. Interprofessional, in situ simulation training for medical deterioration yielded promising outcomes for individuals and teams. Simulation is an under-used training modality in mental health, offering a holistic training approach with the potential to provide educational and clinical benefits while supporting workforce resilience.

Until very recently, an evaluation of US policy regarding deterrence and the role of its nuclear weapons arsenal as a deterrent has been largely absent in the public debate. With President's Obama embrace of a goal of a future world without nuclear weapons, issues of nuclear policy and deterrence have just recently risen to the forefront of policy discussions. The traditional role of US nuclear weapons-to deter the use of nuclear weapons by other states-endures, but is no longer unique nor even predominant. In an increasingly multi-polar world, the US now faces growing risks of nuclear weapons proliferation; the spreadmore » of weapons of mass destruction generally to non-state, substate and transnational actors; cyber, space, economic, environmental and resource threats along with the application of numerous other forms of 'soft power' in ways that are inimical to national security and to global stability. What concept of deterrence should the US seek to maintain in the 21st Century? That question remains fluid and central to the current debate. Recently there has been a renewed focusing of attention on the role of US nuclear weapons and a national discussion about what the underlying policy should be. In this environment, both the United States and Russia have committed to drastic reductions in their nuclear arsenals, while still maintaining forces sufficient to ensure unacceptable consequence in response to acts of aggression. Further, the declared nuclear powers have maintained that a limited nuclear arsenal continues to provide insurance against uncertain developments in a changing world. In this environment of US and Russian stockpile reductions, all declared nuclear states have reiterated the central role which nuclear weapons continue to provide for their supreme national security interests. Given this new environment and the challenges of the next several decades, how might the United States structure its policy and forces with regard to nuclear weapons? Many competing objectives have been stated across the spectrum of political, social, and military thought. These objectives include goals of ratification of the Comprehensive Test Ban Treaty, recommitment to further downsizing of the nuclear arsenal, embracing a long-term goal of the elimination of nuclear weapons, limitations on both the production complex and upgrades to nuclear weapons and delivery systems, and controls and constraints to limit proliferation of nuclear materials and weapons, particularly to rogue states and terrorist groups.« less

Background & objectives: Mosquito control is facing a threat due to the emergence of resistance to synthetic insecticides. Insecticides of plant origin may serve as suitable alternative biocontrol techniques in the future. The purpose of the present study was to assess the ethyl acetate, acetone and methanol extracts of Andrographis paniculata, Eclipta prostrata and Tagetes erecta leaves tested for oviposition-deterrent, ovicidal and repellent activities against malaria vector, Anopheles subpictus Grassi (Diptera: Culicidae). Methods: The dried leaves of the three plants were powdered mechanically and extracted with ethyl acetate, acetone and methanol. One gram of crude extract was first dissolved in 100 ml of acetone (stock solution). From the stock solution, test solution concentrations of 31.21- 499.42 mg/l for oviposition- deterrence assay and repellency and 15.60 - 998.85 mg/l were used in ovicidal assay. The percentage oviposition- deterrence, hatching rate of eggs and protection time were calculated. One-way analysis of variance was used for the multiple concentration tests and for per cent mortality to determine significant treatment differences. Results: The percentage of effective oviposition repellency was highest at 499.42 mg/l and the lowest at 31.21 mg/l in ethyl acetate, acetone and methanol extracts of A. paniculata, E. prostrata and T. erecta. The oviposition activity index (OAI) value of ethyl acetate, acetone and methanol extracts of A. paniculata, E. prostrata and T. erecta at 499.42 mg/l were -0.91, -0.93, -0.84, -0.84, -0.87, -0.82, -0.87, -0.89 and -0.87, respectively. Mortality (no egg hatchability) was 100 per cent with ethyl acetate and methanol extracts of A. paniculata, E. prostrata and T. erecta at 998.85 mg/l. The maximum adult repellent activity was observed at 499.42 mg/l in ethyl acetate extracts of A. paniculata, E. prostrata and methanol extracts of T. erecta, and the mean complete protection time ranged from 120 to 150 min with the different extracts tested. Interpretation & conclusions: The acetone extract of A. paniculata, methanol extract of E. prostrata and T. erecta showed good oviposition-deterrent, ovicidal and repellent activities respectively. These results suggest that the leaf extracts of A. paniculata, E. prostrata and T. erecta may have the potential to be used as an ideal eco-friendly approach for the control of the An. subpictus.

Identifying the effective concentration for spatial repellency of the dengue vector Aedes aegypti

PubMed Central

2012-01-01

Background Current efforts are underway to quantify the chemical concentration in a treated air space that elicits a spatial repellent (deterrent) response in a vector population. Such information will facilitate identifying the optimum active ingredient (AI) dosage and intervention coverage important for the development of spatial repellent tools – one of several novel strategies being evaluated for vector-borne disease control. This study reports initial findings from air sampling experiments conducted under field conditions to describe the relationship between air concentrations of repellent AIs and deterrent behavior in the dengue vector, Aedes aegypti. Methods Air samples were taken inside and outdoors of experimental huts located in Pu Tuey Village, Kanchanaburi Province, Thailand in conjunction with mosquito behavioral evaluations. A mark-release-recapture study design using interception traps was used to measure deterrency of Ae. aegypti against 0.00625% metofluthrin coils and DDT-treated fabric (2g/m2) within separate experimental trials. Sentinel mosquito cohorts were positioned adjacent to air sampling locations to monitor knock down responses to AI within the treated air space. Air samples were analyzed using two techniques: the U.S. Environmental Protection Agency (USEPA) Compendium Method TO-10A and thermal desorption (TD). Results Both the USEPA TO-10A and TD air sampling methods were able to detect and quantify volatized AIs under field conditions. Air samples indicated concentrations of both repellent chemicals below thresholds required for toxic responses (mortality) in mosquitoes. These concentrations elicited up to a 58% and 70% reduction in Ae. aegypti entry (i.e., deterrency) into treated experimental huts using metofluthrin coils and DDT-treated fabric, respectively. Minimal knock down was observed in sentinel mosquito cohorts positioned adjacent to air sampling locations during both chemical evaluations. Conclusions This study is the first to describe two air sampling methodologies that are appropriate for detecting and quantifying repellent chemicals within a treated air space during mosquito behavior evaluations. Results demonstrate that the quantity of AI detected by the mosquito vector, Ae. aegypti, that elicits repellency is far lower than that needed for toxicity. These findings have important implications for evaluation and optimization of new vector control tools that function through mosquito behavior modification as opposed to mortality. PMID:23273133

History of U.S. Nuclear Weapons Doctrine and a Path Forward

NASA Astrophysics Data System (ADS)

Chyba, Christopher

2007-04-01

During the Cold War, the United States considered a number of approaches for living in a world with nuclear weapons, including disarmament, preventive war, the incorporation of nuclear weapons into military strategy, passive and active defense, and deterrence. With the failure of early approaches to disarmament, and the rejection of preventive war against the Soviet Union (and later, China), deterrence became central to key nuclear relationships, though arms control continued to play an important role. The nuclear nonproliferation treaty made preventing the further spread of nuclear weapons another central component of U.S. policy. The Bush Administration has tried to devise a new policy for the post-Cold War period. Their approach has three salient pillars. First, it is characterized by an overall skepticism toward multilateral agreements, on the grounds that bad actors will not obey them, that agreements can lead to a false sense of security, and that such agreements are too often a way for the Lilliputians of the world to tie down Gulliver. The March 2005 U.S. National Defense Strategy declared that U.S. strength ``will continue to be challenged by those who employ a strategy of the weak, using international fora, judicial processes and terrorism.'' Second, the Bush Administration declared its intention to maintain a military dominance so great that other states simply would not try to catch up. The 2002 National Security Strategy states that ``Our forces will be strong enough to dissuade potential adversaries from pursuing a military build-up in hopes of surpassing, or equaling, the power of the United States.'' Third, the 2002 National Security Strategy (reaffirmed by the 2006 National Security Strategy) moved preventive war (which the strategies called ``preemptive war'') to a central position, rather than deterrence and nonproliferation. In part this was because of the claim that certain ``rogue'' states, and terrorist groups, were not deterrable. This talk will sketch this history, discuss the approach of the Bush Administration in more detail and assess its successes and failures, and suggest the lines of a new approach to U.S. nuclear weapons policy for the coming decades. This approach will follow that outlined in George Bunn and Christopher Chyba (eds.), ``U.S. Nuclear Weapons Policy: Confronting Today's Threats'' (Brookings, 2006, 340 pp.).

To examine user acceptance with a new format of charts for recording observations and as a prompt for responding to episodes of clinical deterioration in adult medical-surgical patients. Improving recognition and response to clinical deterioration remains a challenge for acute healthcare institutions globally. Five chart templates were developed in Australia, combining human factors design principles with a track and trigger system for escalation of care. Two chart templates were previously tested in simulations, but none had been evaluated in clinical practice. Prospective multisite survey of user acceptance of the charts in practice. New observation and response charts were trialled in parallel with existing charts for 24 hours across 36 adult acute medical-surgical wards, covering 108 shifts, in five Australian states. Surveys were completed by 477 staff respondents, with open-ended comments and narrative from short informal feedback groups providing elaboration and context of user experiences. Respondents were broadly supportive of the chart format and content for monitoring patients, and as a prompt for escalating care. Some concerns were noted for chart size and style, use of ranges to graph vital signs and with specific human factors design features. Information and training issues were identified to improve usability and adherence to chart guidelines and to support improved detection and response for patients with clinical deterioration. This initial evaluation demonstrated that the charts were perceived as appropriate for documenting observations and as a prompt to detect clinical deterioration. Further evaluation after some minor modifications to the chart is recommended. Explicit training on the principles and rationale of human factors chart design, use of embedded change management strategies and addressing practical issues will improve authentic engagement, staff acceptance and adoption by all clinical users when implementing a similar observation and response chart into practice. © 2016 John Wiley & Sons Ltd.

Socio-economic rehabilitation is an important outcome parameter in successful renal transplant recipients, particularly in developing countries with low income patients who often depend on extraneous sources to fund their surgery costs. We studied the socioeconomic rehabilitation and changes in socioeconomic status (SES) of successful renal allograft recipients among Indian patients and its correlation with their source of funding for the surgery. A cross-sectional, questionnaire-based study was conducted on 183 patients between January 2010 to January 2013. Patients with follow up of at least 1 year after successful renal transplant were included. During interview, two questionnaires were administered, one related to the SES including source of funding before transplantation and another one relating to the same at time of interview. Changes in SES were categorized as improvement, stable and deterioration if post-transplant SES score increased >5%, increased or decreased by <5% and decreased >5% of pre-transplant value, respectively. In this cohort, 97 (52.7%), 67 (36.4%) and 19 (10.3%) patients were non-funded (self-funded), one-time funded and continuous funded, respectively. Fifty-six (30.4%) recipients had improvement in SES, whereas 89 (48.4%) and 38 (20.7%) recipients had deterioration and stable SES. Improvement in SES was seen in 68% patients with continuous funding support whereas, in only 36% and 12% patients with non-funded and onetime funding support (P = 0.001) respectively. Significant correlation was found (R = 0.715) between baseline socioeconomic strata and changes in SES after transplant. 70% of the patients with upper and upper middle class status had improving SES. Patients with middle class, lower middle and lower class had deterioration of SES after transplant in 47.4%, 79.6% and 66.7% patients, respectively. Most of the recipients from middle and lower social strata, which included more than 65% of our patient's population, had deteriorating SES even after a successful transplant. One-time funding source for transplant had significant negative impact on SES and rehabilitation.

Distinct progression of the deterioration of thematic and taxonomic links in natural and manufactured objects in Alzheimer's disease.

PubMed

Simoes Loureiro, Isabelle; Lefebvre, Laurent

2016-10-01

Taxonomic and thematic relationships are core elements of lexico-semantic networks. However, the weight of both links differs in semantic memory, with distinct support for natural and manufactured objects: natural objects tend to be more taxonomically identified while manufactured objects benefit more from the underlying thematic relationships. Alzheimer's disease (AD) causes early semantic memory impairment characterized by a category-specific deterioration, where natural objects are more sensitive to the disease than manufactured objects. However, relatively few studies have examined the progressive deterioration of specific thematic versus taxonomic relations in both categories of objects in AD. To better understand semantic memory disorganization in AD and analyze the potential interaction effect between the category (natural/manufactured), the condition (thematic/taxonomic) and AD, we will investigate the lexico-semantic network in 82 AD patients (divided into three groups depending on their global cognitive deterioration and their performance in a preliminary semantic knowledge questionnaire (mild (AD1), moderate (AD2) and advanced (AD3) stages of semantic knowledge alteration). The experimental protocol contains two tasks: an implicit semantic priming paradigm and an explicit card-sorting test that uses the same items, equally divided between natural and manufactured objects. Results show a distinct taxonomic and thematic evolution pattern with early taxonomic deterioration. Natural objects are also more vulnerable to the disease. Lastly, there is an interaction effect between the category and the condition in the priming task indicating that natural objects are more taxonomically organized and manufactured objects benefit more from both thematic and taxonomic organizations, reinforcing the idea of the robustness of this category. The theoretical accounts of these observations will be discussed in detail. Copyright © 2016 Elsevier Ltd. All rights reserved.

2015-10-01

The last decade has witnessed an exponential growth in user-generated online content featuring Non-Suicidal Self-Injury (NSSI), including photography, digital video, poems, blogging, and drawings. Although the increasing visibility of NSSI content has evoked public concern over potential health risks, little research has investigated why people are drawn to create and publish such content. This article reports the findings from a qualitative analysis of online interviews with 17 individuals who produce NSSI content. A thematic analysis of participants' narratives identified two prominent motives: self-oriented motivation (to express self and creativity, to reflect on NSSI experience, to mitigate self-destructive urges) and social motivation (to support similar others, to seek out peers, to raise social awareness). Participants also reported a double-edged impact of NSSI content both as a trigger and a deterrent to NSSI. © The Author(s) 2015.

Writing-to-learn in undergraduate science education: a community-based, conceptually driven approach.

Reynolds, Julie A; Thaiss, Christopher; Katkin, Wendy; Thompson, Robert J

2012-01-01

Despite substantial evidence that writing can be an effective tool to promote student learning and engagement, writing-to-learn (WTL) practices are still not widely implemented in science, technology, engineering, and mathematics (STEM) disciplines, particularly at research universities. Two major deterrents to progress are the lack of a community of science faculty committed to undertaking and applying the necessary pedagogical research, and the absence of a conceptual framework to systematically guide study designs and integrate findings. To address these issues, we undertook an initiative, supported by the National Science Foundation and sponsored by the Reinvention Center, to build a community of WTL/STEM educators who would undertake a heuristic review of the literature and formulate a conceptual framework. In addition to generating a searchable database of empirically validated and promising WTL practices, our work lays the foundation for multi-university empirical studies of the effectiveness of WTL practices in advancing student learning and engagement.

The recent public outcry following a brutal gang rape of a young woman in India's national capital was a watershed moment in the world's largest democracy. It generated widespread public and political support for strengthening legal provisions to punish sex offenders. Although the legal response is a useful deterrent against such heinous crimes, women continue to suffer due to deeply rooted social prejudices that make them vulnerable to violence and discrimination in society. In this commentary, we aim to analyse the current developments with respect to gender violence in India within a background of the social position of women in Indian society. Using secondary data related to sex-selective abortions and crimes against women, and a critical review of the portrayal of women in Indian cinema, we reflect on the role of health workers, researchers and public health professionals in shaping a social response towards improving gender parity in our country.

PubMed

Ward, Jeffrey T; Krohn, Marvin D; Gibson, Chris L

2014-02-01

This study uses a life course framework to investigate how police contacts may serve as a potential turning point in a violent crime trajectory. Drawing on the central ideas from deterrence and labeling theories, we determine whether individuals on different violent offending trajectories increase or decrease their offending following a police contact. Analyzing nine waves of data from the Rochester Youth Development Study, an integrated propensity score matching and latent class growth model was used. First, three violent trajectory groups emerged including high offenders, non-offenders, and low offenders. Second, after accounting for selection bias using propensity score matching procedures, experiencing a police contact increased the likelihood of future violent offending for the entire sample and for those who were on a low violent-offending trajectory specifically. These findings are interpreted as partial support for labeling theory. Limitations of the study and directions for future research are discussed.

It was indicated that people have an enhanced consciousness on environmental protection, and the relations between this consciousness and economic growth fit Kuznets curve, because most of the poor people are living in the suburban or remote regions with bad or seriously degraded environment, while the fast development of urbanization accelerates the deterioration of urban environment. People are more concerned about environment deterioration, and support the governments' policies of environmental conservation. The environment policy-making should put more emphasis on developing economics, strengthening education, and improving residents' livelihood.

Natural history of idiopathic normal-pressure hydrocephalus (INPH) is not clear. We performed a literature search for studies that looked into the outcome of unshunted INPH patients trying to answer the following questions: Do all INPH patients deteriorate without shunt? If yes, at what rate? Do some NPH patients improve without shunt? If yes, to what extent? Six studies objectively described the outcome of 102 INPH patients. Result shows that without surgery, most INPH patients had measurable deterioration as early as 3 months following initial assessment. A small number of patients might improve without shunt, however the extent of improvement is not clear. The homogeneity of the findings of the cohort studies provided high evidence supporting the rule of shunt surgery in INPH patients.

This monograph examines a new military mission-peace-enforcement. It does so through a five part strategic process that links national interests and national security strategy to tactical operations. it asserts that US national security strategy is evolving as a result of the end of the Cold War and that a new strategy will lead to new military missions. The monograph first describes a limited spectrum of military operations that comprise a peace-enforcement mission. Next, it reviews enduring US national interests then analyzes evolving national security strategy to determine if these elements of strategy support the need for a peace-enforcement mission. Themore » monograph then examines national military strategy, operational level strategy and joint guidance, and finally, US tactical doctrine to determine if peace-enforcement is a mission the US military can execute today. The monograph concludes that national interests and evolving national security strategy will emphasize promotion of democracy and stability in lieu of Cold War deterrence. The national military strategy partially supports this shift; support should increase as the Clinton administration clarifies its policy and solidifies the shift from containment. Lastly, the monograph finds there is sufficient operational and tactical level guidance to conduct the mission and recommends formal acceptance of the peace-enforcement mission into joint doctrine.« less

Background Delay in help seeking for cancer ‘alarm’ symptoms has been identified as a contributor to delayed diagnosis. Aim To understand people’s help-seeking decision making for cancer alarm symptoms, without imposing a cancer context. Design and setting Community-based, qualitative interview study in the UK, using purposive sampling by sex, socioeconomic status, and prior help seeking, with framework analysis of transcripts. Method Interviewees (n = 48) were recruited from a community-based sample (n = 1724) of adults aged ≥50 years who completed a health survey that included a list of symptoms. Cancer was not mentioned. Participants reporting any of 10 cancer alarm symptoms (n = 915) and who had consented to contact (n = 482) formed the potential pool from which people were invited to an interview focusing on their symptom experiences. Results Reasons for help seeking included symptom persistence, social influence, awareness/fear of a link with cancer, and ‘just instinct’. Perceiving the symptom as trivial or ‘normal’ was a deterrent, as was stoicism, adopting self-management strategies, and fear of investigations. Negative attitudes to help seeking were common. Participants did not want to be seen as making a fuss, did not want to waste the doctor’s time, and were sometimes not confident that the GP could help. Conclusion Decision making about cancer alarm symptoms was complex. Recognition of cancer risk almost always motivated help seeking (more so than the fear of cancer being a deterrent), assisted by recent public-awareness campaigns. As well as symptom persistence motivating help seeking, it could also have the reverse effect. Negative attitudes to help seeking were significant deterrents. PMID:25624313

In large parts of Europe, insecticide-free measures for protecting conifer plants are desired to suppress damage by the pine weevil Hylobius abietis (L.). Treatment with methyl jasmonate (MeJA), a chemical elicitor already used in crop production, may enhance expression of chemical defenses in seedlings in conifer regenerations. However, in a previous experiment, MeJA treatment resulted in substantially better field protection for Scots pine (Pinus sylvestris L.) than for Norway spruce (Picea abies (L.) Karst.). Hypothesizing that the variations may be at least due partly to volatiles released by MeJA-treated seedlings and their effects on pine weevil orientation, we examined tissue extracts of seedlings (from the same batches as previously used) by two-dimensional GC-MS. We found that the MeJA treatment increased contents of the monoterpene (-)-β-pinene in phloem (the weevil's main target tissue) of both tree species, however, the (-)-β-pinene/(-)-α-pinene ratio increased more in the phloem of P. sylvestris. We also tested the attractiveness of individual monoterpenes found in conifer tissues (needles and phloem) for pine weevils using an arena with traps baited with single-substance dispensers and pine twigs. Trap catches were reduced when the pine material was combined with a dispenser releasing (-)-β-pinene, (+)-3-carene, (-)-bornyl acetate or 1,8-cineole. However, (-)-α-pinene did not have this effect. Thus, the greater field protection of MeJA-treated P. sylvestris seedlings may be due to the selective induction of increases in contents of the deterrent (-)-β-pinene, in contrast to strong increases in both non-deterrent (-)-α-pinene and the deterrent (-)-β-pinene in P. abies seedlings.

After 9/11, network analysis became popular as a way to connect and disconnect the dots. It was heralded as the new science with intrinsic value for understanding and breaking up terrorist groups, insurgencies and hostile foreign governments. The limit of the initially forwarded approach was that it focused on only the social network -- who talked to whom. However ,the networks of war, terror or nuclear or cyber, are complex networks composed of people, organizations, resources, and capabilities connected in a geo-temporal web that constrains and enables activities that are ``hidden'' in the web of everyday life. Identifying these networks requires extraction and fusion of information from cyber-mediated realms resulting in a network map of the hostile groups and their relations to the populations in which they are embedded. These data are at best a sample, albeit a very large sample, replete with missing and incomplete data. Geo-temporal considerations in addition to information loss and error called into question the value of traditional network approaches. In this talk, a new approaches and associated technologies that integrate scientific advances in machine learning, network statistics, and the social and organizational science with traditional graph theoretic approaches to social networks are presented. Then, examples, of how these technologies can be used as part of a deterrence strategy are described. Examples related to terrorism and groups such as al-Qaida and Hamas, cyber and nuclear deterrence are described. By taking this meta-network approach, embracing the complexity and simultaneously examining not just one network, but the connections among networks, it is possible to identify emergent leaders, locate changes in activities, and forecast the potential impact of various interventions. Key challenges, such as data-streaming and deception, that need to be addressed scientifically are referenced.

The proliferation in quantity and quality of weapons of mass destruction serve as a threat of great consequence to U.S. operational forces. Operational options for action are explored within the national military strategy concepts of forward presence, deterrence, and crisis/regional contingency response. Three questions and associated issues related to operational art are posed for each concept: (1) what condition must be produced to achieve the strategic goal, (2) what events will most likely result in the desired condition, and (3) how should resources be applied to produce those events. The resulting analysis offers the following conclusions: (1) complementary efforts bymore » all instruments of national power--political, diplomatic, economic, and military--are necessary; (2) knowledge, training, and equipment are the first line of defense; (3) persuasion as well as confrontation is necessary; (4) effective deterrence requires capability, credibility, and communication; and (5) training and weapons for retaliation-in-kind remain the final alternative.« less

Joseph A. Burton Forum Award: Some Nuclear Weapons Dilemmas

May, Michael

2014-03-01

Nuclear weapons pose a combination of political and ethical dilemmas the solution to which has not been found. On one hand, in the view of both US government leaders and US allies, nuclear deterrence continues to play an essential part in the US role as the ultimate source of military strength for the alliances among the major democratic countries. It also continues to be in demand by countries that believe themselves to be isolated and threatened. On the other hand, nuclear weapons, besides being effective deterrents, can cause unprecedented loss of life and risk the demise of civilizations. No ban or technical precaution could prevent the rebuilding of nuclear weapons in a crisis. No diplomatic arrangement to date has erased the threat of invasion and war in the world. Only the abandonment of war and the threat of war as instruments of policy can make nuclear weapons obsolete. The slow, halting, risky road to that end remains the only hope for a world in which lasting solutions to the nuclear dilemmas are possible.
