Avoidance
Kinds of Avoidance Terms modified by Avoidance Selected AbstractsINCREASED AVOIDANCE OF SWIMMERS BY WILD BOTTLENOSE DOLPHINS (TURSIOPS TRUNCATUS) DUE TO LONG-TERM EXPOSURE TO SWIM-WITH-DOLPHIN TOURISMMARINE MAMMAL SCIENCE, Issue 4 2001Rochelle Constantine Abstract The responses of wild, non-provisioned bottlenose dolphins (Tursiops truncatus) to swim attempts from commercial swim-with-dolphin tour boats were systematically observed during two research periods: 1994,1995 and 1997,1998. A total of 255 groups of dolphins was encountered during boat-based surveys and 36% (n= 93) were exposed to at least one swim attempt. The operators' success with swim attempts, defined as at least one dolphin milling within 5 m of at least one swimmer, decreased from 48% in 1994,1995 to 34% in 1997,1998, and avoidance responses to swimmers increased from 22% to 31%. Dolphin response was found to vary according to swimmer placement. The greatest increase in avoidance occurred when swimmers were placed in the dolphins' path of travel. Based on sighting records of 266 individually identified dolphins, it was estimated that an average dolphin was exposed to 31 swim attempts per year. This level of exposure suggests that individual dolphins have, with cumulative experience, become sensitized to swim attempts. When a swim attempt was successful, on average it involved 19% of the group. Age-class differences in interaction rates showed that juveniles were significantly more likely to interact with swimmers than adults. This study highlights the importance of longitudinal studies in evaluating human impact and suggests the urgent need for similar studies of potential human impact on other toothed cetaceans. [source] SENSUAL ATTACHMENT AND INCEST AVOIDANCE IN HUMAN EVOLUTION AND CHILD DEVELOPMENTTHE JOURNAL OF THE ROYAL ANTHROPOLOGICAL INSTITUTE, Issue 4 2005John M. Ingham The authors take issue with the critique of psychoanalysis and the depiction of human sexuality and incest avoidance in evolutionary psychology. Drawing on human neurobiology and evolutionary anthropology, they show that human beings have an evolved disposition toward pair-bonding and evolved capacities for self-regulation of sexual and aggressive impulses. The realization that these characteristics are not only important but also interrelated leads to a reassessment of the Oedipus complex, a new model of incest avoidance in humans, and a fresh perspective on the relation between reproductive behaviour and environmental conditions. [source] DEADLOCK AVOIDANCE FOR FLEXIBLE MANUFACTURING SYSTEMS WITH CHOICES BASED ON DIGRAPH CIRCUIT ANALYSISASIAN JOURNAL OF CONTROL, Issue 2 2007Wenle Zhang ABSTRACT Due to existence of concurrent part flows and resource sharing in modern automated flexible manufacturing systems (FMS), deadlock is a common problem and its occurrence causes loss of productivity. When a manufacturing system is modeled by a digraph, existence of circuits in such a graph is a necessary condition for deadlock. Our previous work further showed that the knot and order of a circuit is closely related to impending deadlocks , a type of deadlock that is more difficult to detect. In this paper, we extend our previous work on deadlock avoidance for flexible manufacturing systems to allow choices in process flows (a.k.a., flexible part routing). Due to introduction of choices, part flow dynamics become more sophisticated and our previous results are no longer valid. A systematic circuit analysis is performed in this paper. New concepts such as broken circuit, basic circuit, choice circuit and supremal circuit are introduced to reduce significantly the number of circuits thus improving efficiency of our approach. The extended method is highly permissive with the adjusted effective free space calculation to capture more necessary parts flow dynamics, especially when multiple knots exist in the digraph model. The online policy runs in polynomial time once the set of basic circuits of the digraph is computed offline. Simulation results on selected examples are given. [source] Understanding the Search for Meaning in Life: Personality, Cognitive Style, and the Dynamic Between Seeking and Experiencing MeaningJOURNAL OF PERSONALITY, Issue 2 2008Michael F. Steger ABSTRACT Although several theories assert that understanding the search for meaning in life is important, empirical research on this construct is sparse. Three studies provide the first extensive effort to understand the correlates of the search for meaning in a multistudy research program. Assessed were relations between search for meaning and well-being, cognitive style, and the Big Five, Big Three, Approach/Avoidance, and Interest models of personality, with a particular emphasis on understanding the correlates of search for meaning that are independent of presence of meaning. Conceptual models of the relation between search and presence were tested. Findings suggest that people lacking meaning search for it; the search for meaning did not appear to lead to its presence. Study 3 found that basic motive dispositions moderated relations between search for meaning and its presence. Results highlight the importance of basic personality dispositions in understanding the search for meaning and its correlates. [source] Rapid Human-Assisted Creation of Bounding Models for Obstacle Avoidance in ConstructionCOMPUTER-AIDED CIVIL AND INFRASTRUCTURE ENGINEERING, Issue 1 2004J. McLaughlin A practical, interactive method for doing so is described here. The method: (1) exploits a human operator's ability to quickly recognize significant objects or clusters of objects in a scene, (2) exploits the operator's ability to acquire sparse range point clouds of the objects quickly, and then (3) renders models, such as planes, boxes, and generalized convex hulls, to be displayed graphically as visual feedback during equipment operation and/or for making proximity calculations in an obstacle detection system. Experiments were performed in which test subjects were asked to model objects of varying complexity and clutter. These models were then compared to control models using a ray-tracing algorithm to determine the operator's ability to create conservative models that are critical to construction operations. To demonstrate the applicability of the modeling method to obstacle avoidance, a scripted motion robot simulation was conducted using an artificial potential formulation that monitors position (closest point on manipulator link to nearest obstacle) as well as velocity (link inertia). Experimental results indicate that bounding models can be created rapidly and with sufficient accuracy for obstacle avoidance with the aid of human intelligence and that human-assisted modeling can be very beneficial for real-time construction equipment control. [source] Avoidance by grazers facilitates spread of an invasive hybrid plantECOLOGY LETTERS, Issue 2 2010E. Grosholz Ecology Letters (2010) 13: 145,153 Abstract Biological invasions greatly increase the potential for hybridization among native and non-native species. Hybridization may influence the palatability of novel hybrids to consumers potentially influencing invasion success; however, the palatability of non-native hybrids relative to the parent species is poorly known. In contrast, studies of native-only hybrids find they are nearly always more palatable to consumers than the parent species. Here, I experimentally demonstrate that an invasive hybrid cordgrass (Spartina) is dramatically less palatable to grazing geese than the native parent species. Using field and aviary experiments, I show that grazing geese ignore the hybrid cordgrass and preferentially consume native Spartina. I also experimentally demonstrate that reduced herbivory of the invasive hybrid may contribute to faster spread in a California estuary. These results suggest that biological invasions may increase future opportunities for creating novel hybrids that may pose a greater risk to natural systems than the parent species. [source] Equine recurrent uveitis: A clinical manifestation of leptospirosisEQUINE VETERINARY EDUCATION, Issue 10 2009L. Frellstedt Summary Leptospirosis is a zoonosis of worldwide distribution affecting domestic animals, wildlife and man. The bacterial disease is caused by pathogenic Leptospira spp., which are transmitted from reservoir hosts to accidental hosts. Horses are accidental hosts and can become susceptible to leptospiral infections. Widespread exposure to leptospires exists and is significantly more common than clinical disease. Leptospirosis can have different clinical manifestations including abortion, still birth, systemic disease with hepatic or renal dysfunction, and equine recurrent uveitis (ERU). ERU is the most frequently encountered clinical manifestation and this article will focus on the review of leptospira-associated ERU. Equine recurrent uveitis is the most common cause of vision impairment and blindness in horses. The pathogenesis of leptospira-associated ERU involves direct bacterial effects and immune-mediated responses. Clinical signs vary between the acute and chronic phases of the disease and progress over time. The diagnosis of leptospira-associated ERU can be difficult and usually requires a combination of diagnostic tests. Medical and surgical treatments have been described with varying outcomes. The prognosis for sight is usually poor, although core vitrectomy may improve the outcome. Avoidance of leptospiral exposure of horses is the only reliable prevention of leptospira-associated disease. [source] Comparison of three models of alcohol craving in young adults: a cross-validationADDICTION, Issue 4 2004Peter M. McEvoy ABSTRACT Aims The aim of study 1 was to develop a three-factor Approach and Avoidance of Alcohol Questionnaire (AAAQ), designed to assess mild and intense inclinations to drink, as well as inclinations to avoid drinking. The aims of study 2 were to cross-validate the AAAQ with an independent sample and to test the goodness-of-fit of three models of craving for alcohol: (a) the traditional unidimensional model; (b) a two-dimensional, approach,avoidance ambivalence model; and (c) an expanded two-dimensional neuroanatomical model that retains avoidance, while positing a threshold that partitions approach into two distinct levels and relates all three factors involved in craving to brain pathways associated with inhibitory processes, reward and obsessive,compulsive behaviour, respectively. Design, setting and participants The survey was administered to 589 Australian university students (69% women) in study 1 and to 523 American university students (64% women) in study 2. Measurements Inclinations to drink and to not drink (AAAQ), drinking behaviour (quantity and frequency), drinking problems (Young Adult Alcohol Problems Screening Test; YAAPST) and readiness for change (Stages of Change Readiness and Treatment Eagerness Scale; SOCRATES). Findings The expanded two-dimensional neuroanatomical model provided the best fit to the data. The AAAQ explained a substantial proportion of the variance in drinking frequency (41,53%), drinking quantity (49,60%) and drinking problems (43%). AAAQ profiles differed as a function of drinking-related risk, and the three AAAQ scales differentially predicted readiness for change. Conclusions Approach and avoidance inclinations toward alcohol are separable constructs, and their activation may not be invariably reciprocal. Craving can be defined as the relative activation of substance-related response inclinations along these two primary dimensions. There may be a threshold of intensity that separates mild from intense approach inclinations. [source] Premating Avoidance of Inbreeding Absent in Female Guppies (Poecilia reticulata)ETHOLOGY, Issue 7 2006Åslaug Viken The recognition and avoidance of kin during mating can be an important means of reducing the potential for inbreeding depression in offspring. We report here that premating mechanisms to avoid inbreeding, either innate or learnt through juvenile experience, are at best weak in female guppies (Poecilia reticulata). Guppies are small, ovoviviparous, neo-tropical freshwater fish, with a polygamous mating system where males actively court females and females are selective of their mates. In a series of mate-choice experiments, naïve, virgin females of the Quare River population in Trinidad were given a choice between a brother and a non-sib male from the same population. Initially, females were only provided olfactory cues upon which to base their choice and then subsequently both olfactory and visual cues. Despite the females displaying mate choice, we found no evidence of them discriminating between the male types in either experiment. There was thus no indication of inbreeding avoidance, suggesting that experiences after maturation or with mature males (e.g. rare male preference), dispersal and/or post-mating mechanisms may be evolutionarily more important avoidance mechanisms. [source] Avoidance of Chemical Alarm Cues Released from Autotomized Tails of Ravine Salamanders (Plethodon richmondi)ETHOLOGY, Issue 4 2001Jeffery A. Hucko The ability of animals to detect and avoid areas containing chemical alarm cues from conspecifics is well documented in aquatic species. The ability to detect chemical alarm cues in terrestrial organisms has not been tested until recently. In this study, we tested the ability of the ravine salamander (Plethodon richmondi) to detect and avoid areas containing chemicals released from the autotomized tails of conspecifics and sympatric zigzag salamanders (P. dorsalis). We also ascertained whether any avoidance response could be attributed to the size or sex of the animal. Our results suggest that ravine salamanders avoid substrates containing odors released from the autotomized tails of conspecifics, but not of heterospecific salamanders and that this response occurs independent of the size and/or sex of the animal. By avoiding areas where a conspecific has recently been injured, an organism could reduce its chances of encountering a predator and thus increase its chances of survival. [source] Detection and Avoidance of Predators in White-Tailed Deer (Odocoileus virginianus) and Mule Deer (O. hemionus)ETHOLOGY, Issue 2 2001Susan Lingle In this paper, we investigate the relationship between early detection of predators and predator avoidance in white-tailed deer (Odocoileus virginianus) and mule deer (O. hemionus), two closely related species that differ in their habitat preferences and in their anti-predator behavior. We used observations of coyotes (Canis latrans) hunting deer to test whether the distance at which white-tails and mule deer alerted to coyotes was related to their vulnerability to predation. Coyote encounters with both species were more likely to escalate when deer alerted at shorter distances. However, coyote encounters with mule deer progressed further than encounters with white-tails that alerted at the same distance, and this was not due to species differences in group size or habitat. We then conducted an experiment in which a person approached groups of deer to compare the detection abilities and the form of alert response for white-tails and mule deer, and for age groups within each species. Mule deer alerted to the approacher at longer distances than white-tails, even after controlling for variables that were potentially confounding. Adult females of both species alerted sooner than conspecific juveniles. Mule deer almost always looked directly at the approacher as their initial response, whereas white-tails were more likely to flee or to look in another direction with no indication that they pinpointed the approacher during the trial. Mule deer may have evolved the ability to detect predators earlier than white-tails as an adaptation to their more open habitats, or because they need more time to coordinate subsequent anti-predator defenses. [source] Headaches Amongst Pool PlayersHEADACHE, Issue 2 2007Raymond C.S. Seet MRCP Background.,Pool-players' headache is a newly described entity. We studied the prevalence and risk factors for the development of headaches amongst pool players. Methods.,We obtained demographic information, history of pre-existing headaches, frequency and duration of pool-playing, history of pre-existing headaches and their subtypes, competitive pool-playing and worsening or development of headaches amongst pool-players at 2 pool centers. Univariate and multivariate analyses were performed and statistical significance was set at P < .05. Results.,Two hundred and three players, of mean age 22.6 (SD 7.7 years), participated in this study. Of the 21 respondents who reported headaches when playing pool, 11 (52.4%) had pre-existing headaches and 10 (47.6%) had no pre-existing headaches. Age and history of pre-existing headaches were significantly associated with worsening of headaches. Conclusion.,Pool-players are susceptible to the development of headaches. Avoidance and reduction in the frequency of pool-playing may reduce the frequency of headaches amongst pool players. [source] A functional hypothesis for adult hippocampal neurogenesis: Avoidance of catastrophic interference in the dentate gyrusHIPPOCAMPUS, Issue 3 2006Laurenz Wiskott Abstract The dentate gyrus is part of the hippocampal memory system and special in that it generates new neurons throughout life. Here we discuss the question of what the functional role of these new neurons might be. Our hypothesis is that they help the dentate gyrus to avoid the problem of catastrophic interference when adapting to new environments. We assume that old neurons are rather stable and preserve an optimal encoding learned for known environments while new neurons are plastic to adapt to those features that are qualitatively new in a new environment. A simple network simulation demonstrates that adding new plastic neurons is indeed a successful strategy for adaptation without catastrophic interference. © 2006 Wiley-Liss, Inc.

Afifi First page of article [source] A Cylindrical Model of Communication Behavior in Crisis NegotiationsHUMAN COMMUNICATION RESEARCH, Issue 1 2002Paul J. Taylor This article integrates existing theoretical perspectives on message content and negotiator motivation to formulate a comprehensive definitional model of the interrelationships among communication behaviors in crisis negotiation. A sample of 189 nuclear dialogue spans were transcribed from 9 resolved cases of hostage negotiation and each utterance coded at the level of thought units across 41 behavioral variables. Results of a nonmetric, multidimensional scaling solution provided clear support for the hypothesized cylindrical structure of communication behavior, revealing 3 dominant levels of suspect-negotiator interaction (Avoidance, Distributive, Integrative). At each level of the structure, interactions were found to modulate around 3 thematic styles of communication (Identity, Instrumental, Relational), which reflected the underlying motivational emphasis of individuals' dialogue. Finally, the intensity of communication was found to play a polarizing role in the cylinder, with intense, functionally discrete behaviors occurring toward the boundary of the structure. [source] Maternal self-efficacy beliefs, competence in parenting, and toddlers' behavior and developmental statusINFANT MENTAL HEALTH JOURNAL, Issue 2 2003Priscilla K. Coleman This study was designed to examine parenting self-efficacy beliefs as correlates of mothers' competence in parenting toddlers and as predictors of toddlers' behavior and development. Sixty-eight predominantly middle-class mother,toddler pairs participated in this study. Mothers completed questionnaires, toddlers were administered the Bayley Scales of Infant Development (BSID-II), and each dyad participated in the Crowell Procedure, which is designed to observe parent and toddler behaviors in a semistructured laboratory context. Although domain-general and domain-specific parenting self-efficacy beliefs were not associated with parenting competence, domain-specific beliefs were significantly related to toddlers' scores on the Mental Scale of the BSID-II and several behaviors observed during the Crowell Procedure (Affection Towards Mother, Avoidance of Mother, Compliance, Enthusiasm, and Negativity). Implications of the findings are discussed. ©2003 Michigan Association for Infant Mental Health. [source] Psychopathology and autobiographical memory in stroke and non-stroke hospitalized patientsINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 1 2003Mark John Sampson Abstract Background Psychopathology and autobiographical memory were investigated in a cohort of stroke and non-stroke hospitalized patients. Both these cohorts have been identified as having high levels of psychopathology (Katon and Sullivan 1990; Burvill et al., 1995). Difficulties recalling specific autobiographical memories (overgeneral memory) have been identified as important psychological variables in depression and predictors of outcome (Williams and Scott 1988; Brittlebank et al., 1993). Intrusive autobiographical memories have also been found to be associated with depression and overgeneral memory in depressed women (Kuyken and Brewin, 1995) and depressed cancer patients (Brewin et al., 1998a). This study looked at levels of psychopathology and autobiographical memories in stroke and non-stroke hospital patients. Method 417 patients were screened, of the 176 eligible 103 agreed to participate (54 stroke and 49 non-stroke). Participants were assessed for overgenerality using the Autobiographical Memory Test and intrusiveness of memories using the Impact of Events Scale. Also assessed were PTSD-like symptoms (PCL-S), mood (HADS, GHQ-28) and cognitive ability (MMSE, verbal fluency, digit span and estimated pre-morbid IQ). Results No significant differences were found between stroke and non-stroke patients on severity of depression, anxiety, severity of PTSD-like symptoms or autobiographical memories. Backward multivariate regression analyses for combined data (stroke and non-stroke) indicated that overgeneral memory recall, intrusive memories of past events and intrusive memories of illness were significant independent predictors of depression (HADS). Avoidance of intrusive memories and reported childhood distress were not predictors of overgeneral memory recall. Significant predictors of overgeneral memory recall were; Gender, antidepressant medication, and estimated IQ. Conclusion Significant levels of psychopathology were identified in this cohort. However, there were no significant differences in the levels of depression, anxiety, PTSD symptoms and autobiographical memory between stroke and non-stroke hospitalized patients. Of particular interest was the finding that PTSD-like symptoms did not appear to be influenced by the nature of the person's illness. In combined data (stroke and non-stroke) autobiographical memories (intrusive images of their illness, intrusive memories of other events and overgeneral memory recall variables) were significant predictors of depression in this cohort. This suggests that psychological intervention of memory processes may be a worthwhile target in psychological intervention for depression in these cohorts. Gender, cognitive impairment, antidepressant medication, and estimated IQ were significant predictors of overgeneral memory recall and further investigation into the validity of these findings are warranted. Suggestions for further research and limitations of the study are also discussed. Copyright © 2002 John Wiley & Sons, Ltd. [source] Instinctive Incest Avoidance: A Paradigm Case for Evolutionary Psychology EvaporatesJOURNAL FOR THE THEORY OF SOCIAL BEHAVIOUR, Issue 4 2006JUSTIN LEIBER Westermarck proposed that humans have an incest avoidance instinct, triggered by frequent intimate contact with family members during the first several years of life. Westermarck reasons that (1) familial incest will tend to produce less fit offspring, (2) those humans without instinctive incest avoidance would hence have tended to die off and those with the avoidance instinct would have produced more viable offspring, and hence (3) familial incest would be, as indeed it is, universally and instinctively avoided (the desire simply does arise given early continuous intimate contact; the "potty principle" as some psychologists have succinctly termed it). Victorian Westermarck claimed this as a human adaptation. Evolutionary psychologists have generalized these claims to Pleistocene humans and their ancestors, to primates, and indeed to animals generally. Yet there is surprisingly little evidence for these claims of universal instinctive avoidance. Considerable inbreeding appears among large, territorial primates and may have been so with early humans and with their ancestors. While there is little reliable non-anecdotal evidence about incestuous behavior or the lack of it among humans, what little there is does not fit well with the Westermarck thesis. [source] Association Between Dietary Quality of Rural Older Adults and Self-Reported Food Avoidance and Food Modification Due to Oral Health ProblemsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 7 2010Margaret R. Savoca PhD OBJECTIVES: To quantify the association between food avoidance and modification due to oral health problems, to examine the association between food practices and dietary quality, and to determine foods associated with these self-management behaviors. DESIGN: Cross-sectional. SETTING: Rural North Carolina. PARTICIPANTS: Six hundred thirty-five community-dwelling adults aged 60 and older. MEASUREMENTS: Demographic and food frequency data and oral health assessments were obtained during home visits. Avoidance (0, 1,2 foods, 3,14 foods) and modification (0,3 foods, 4,5 foods) due to oral health problems were assessed for foods representing oral health challenges. Food frequency data were converted into Healthy Eating Index-2005 (HEI-2005) scores. Linear regression models tested the significance of associations between HEI-2005 measures and food avoidance and modification. RESULTS: Thirty-five percent of participants avoided three to 14 foods, and 28% modified four to five foods. After adjusting for age, sex, ethnicity, poverty, education, and tooth loss, total HEI-2005 score was lower (P<.001) for persons avoiding more foods and higher for persons modifying more foods (P<.001). Those avoiding three to 14 foods consumed more saturated fat and energy from solid fat and added sugar and less nonhydrogenated fat than those avoiding fewer than three foods. Those who modified four to five foods consumed less saturated fat and solid fat and added sugar but more total grains than those modifying fewer than four foods. CONCLUSION: Food avoidance and modification due to oral health problems are associated with significant differences in dietary quality. Approaches to minimize food avoidance and promote food modification by persons having eating difficulties due to oral health conditions are needed.

[source] Obstacle Avoidance for Spatial Hyper-Redundant Manipulators Using Harmonic Potential Functions and the Mode Shape TechniqueJOURNAL OF FIELD ROBOTICS (FORMERLY JOURNAL OF ROBOTIC SYSTEMS), Issue 1 2003F. Fahimi This paper deals with the obstacle avoidance problem for spatial hyper-redundant manipulators in known environments. The manipulator is divided into two sections, a proximal section that has not entered the space among the obstacles and a distal section among the obstacles. Harmonic potential functions are employed to achieve obstacle avoidance for the distal section in three-dimensional space in order to avoid local minima in cluttered environments. A modified panel method is used to generate the potential of any arbitrary shaped obstacle in three-dimensional space. An alternative backbone curve concept and an efficient fitting method are introduced to control the trajectory of proximal links. The fitting method is recursive and avoids the complications involved with solving large systems of nonlinear algebraic equations. The combination of a three-dimensional safe path derived from the harmonic potential field and the backbone curve concept leads to an elegant kinematic control strategy that guarantees obstacle avoidance. © 2003 Wiley Periodicals, Inc. [source] Regulation Avoidance in the Banking Industry: The Case of 364 Day Lines of CreditJOURNAL OF INTERNATIONAL FINANCIAL MANAGEMENT & ACCOUNTING, Issue 3 2000Michael Mosebach The purpose of this case is to offer a demonstration of Kane's regulatory dialectic and to discuss a line of credit that is a result of the interaction between the regulators and the regulated. Banks have been affected by new capital requirements. Calculation of these requirements considers not only on-balance sheet activities but off-balance sheet activities. Prior to these requirements, banks issued one year lines of credit for 365 days. These lines of credit have since been replaced with 364 day lines of credit. With maturity less than one year, the percentage of lines of credit considered in the calculations for required capital is reduced from 50% to 20%. Lines of credit are well established financial instruments and there is no reason, other than the changes in regulations, to make banks change the maturity dates by one day. [source] Detection Avoidance and Deterrence: Some Paradoxical ArithmeticJOURNAL OF PUBLIC ECONOMIC THEORY, Issue 3 2008ERIC LANGLAIS This paper extends Malik's analysis to the case where criminals' avoidance efforts and public expenditures in the detection of criminals are strategic complements in the aggregate technology of control of illegal behaviors. In this set up, we show that whenever criminals' avoidance efforts are more sensitive to the frequency than to the severity of sanctions, it is always socially efficient to set the fine at the maximal possible level. However, several paradoxical consequences occur: there may exist overdeterrence at optimum; more repressive policies lead to fewer arrests of offenders while more crimes may be committed; at the same time, the society may be closer to the first best number of crimes. [source] Ethanol-Induced Conditioned Taste Avoidance: Reward or Aversion?ALCOHOLISM, Issue 3 2009Chuang Liu Background:, Rats avoid intake of a palatable taste cue when paired with all drugs of abuse tested. Evidence suggests that, at least for morphine and cocaine, rats avoid the taste cue because they are anticipating the rewarding properties of the drug. Thus, the suppressive effects of a rewarding sucrose solution and cocaine, but not those of the putatively aversive agent, lithium chloride (LiCl), are exaggerated in drug-sensitive Lewis rats. Likewise, the suppressive effects of sucrose and morphine, but not those of LiCl, are eliminated by bilateral lesions of the gustatory thalamus. Unlike morphine and cocaine, it is less clear whether rewarding or aversive drug properties are responsible for ethanol-induced suppression of intake of a taste cue. The present set of studies tests whether, like cocaine, ethanol-induced suppression of intake of a taste cue also is greater in the drug-sensitive Lewis rats and whether the suppressive effects of the drug are prevented by bilateral lesions of the taste thalamus. Methods:, In Experiment 1, fluid-deprived Lewis and Fischer rats were given 5-minute access to 0.15% saccharin and then injected with saline or a range of doses of ethanol (0.5, 0.75, 1.0, or 1.5 g/kg). There was a total of 6 such pairings. In Experiments 2 and 3, Sprague,Dawley rats received bilateral electrophysiologically guided lesions of the gustatory thalamus. After recovery, suppression of intake of the saccharin cue was evaluated following repeated daily pairings with either a high (1.5 g/kg) or a low (0.75 g/kg) dose of ethanol. Results:, Ethanol-induced suppression of intake of the saccharin conditioned stimulus (CS) did not differ between the drug-sensitive Lewis rats relative to the less-sensitive Fischer rats. Lesions of the taste thalamus, however, prevented the suppressive effect of the 0.75 g/kg dose of the drug, but had no impact on the suppressive effect of the 1.5 g/kg dose of ethanol. Conclusion:, The results suggest that the suppressive effects of ethanol on CS intake are mediated by both rewarding and aversive consequences, varying as a function of dose. [source] Avoidance of Alcohol-Related Stimuli in Alcohol-Dependent InpatientsALCOHOLISM, Issue 8 2007J. M. Townshend Background: Previous research has shown an attentional bias toward drug-related stimuli in heavy social drinkers. Attentional orientation to drug-related cues may lead to increased craving and preoccupation with the drug and impaired ability to focus attention on nondrug-related activities, resulting in renewed drug taking or relapse from drug abstinence. Objective: The aim of this study was to investigate whether alcohol-dependent inpatients would differ in their selective attention toward alcohol-related stimuli in comparison with a group of social drinking controls. Method: Thirty-five alcohol-dependent inpatients were compared with a group of 39 social drinking controls matched for age, sex, and verbal IQ. Attentional bias was assessed using alcohol-related pictures in a dot probe detection task. Questionnaires were used to examine outcome expectancies after alcohol consumption, anxiety, mood, and craving. Results: The alcoholic inpatients showed a bias away from the alcohol-related stimuli, scored higher on alcohol outcome expectancies, and on anxiety measures (both state and trait). They also presented with more negative mood compared with the control group. Craving was higher in the alcoholic group for the factor "loss of control over drinking." Conclusions: Alcoholic inpatients undergoing treatment based on the 12-step treatment of Alcoholics Anonymous (Minnesota model), which includes counseling, and intensive group, individual, and family psychotherapy, show an avoidance for drug-related stimuli and a perception of loss of control over drinking. We suggest that their increased perception of loss of control over drinking produces the avoidance from the drug-related stimuli. [source] Nurse Practitioner, Nurse Midwife and Physician Assistant Attitudes and Care Practices Related to Persons with HIV/AIDSJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 2 2000Jane E. Martin RN ABSTRACT Although multiple studies of nurses' attitudes toward people living with HIV/AIDS (PLWAs) can be found in the literature, little is known about the attitudes, beliefs and practices of nurse practitioners (NPs), certified nurse midwives (CNMs), and physician assistants (PAs). A survey including a 21-item AIDS Attitude Scale measuring the constructs of Avoidance and Empathy was sent to 1,291 NPs, CNMs and PAs in Louisiana, Arkansas and Mississippi to describe their attitudes and care practices related to PLWAs. Respondents who were more comfortable treating PLWAs had significantly lower avoidance scores and significantly higher empathy scores than respondents with lower comfort levels in providing care. Greater than 80% of respondents indicated that they would provide health care to HIV-infected individuals. Respondents who referred HIV/AIDS patients for all care did so primarily due to lack of experience with HIV and the availability of more experienced providers. Avoidance and empathy scores were not found to be significantly associated with referral for care. This study suggests that this group of providers has relatively low avoidance and high empathy toward PLWAs and is willing to care for HIV-infected individuals. This study was supported by Grant No. 5U69PE00112-06 from the Department of Health & Human Services, Health Resources and Services Administration, HIV/AIDS Bureau, National AIDS Education and Training Center. [source] Criterion for the Avoidance of Edge Cracking in Layered SystemsJOURNAL OF THE AMERICAN CERAMIC SOCIETY, Issue 8 2004M. Y. He When fabricating multilayers with brittle constituents, a prevalent design strategy is to choose fabrication conditions and thermal expansion coefficients that impose in-plane compression on the brittle layers. In such designs, a small zone of out-of-plane tension is induced at the edges that can cause cracks to form and extend, especially along the midplane. The associated stresses and energy release rates have been analyzed, revealing a fail-safe criterion, attributed to the existence of a maximum possible energy release rate, Gmax. Equating this maximum to the toughness defines a fail-safe parameter expressing the influence of the layer thickness, the misfit stress, and the toughness. When fail-safe designs cannot be realized, thin interlayers can be interposed in a manner that diminishes Gmax, broadening accessibility. The roles of misfit stress and interlayer thickness in attaining this condition are derived. [source] Patterns in current anaesthesiological peri-operative practice for colonic resections: a survey in five northern-European countriesACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 9 2006P. Hannemann Background:, For colorectal surgery, evidence suggests that optimal management includes: no pre-operative fasting, a thoracic epidural analgesia continued for 2 days post-operatively, and avoidance of fluid overload. In addition, no long-acting benzodiazepines on the day of surgery and use of short-acting anaesthetic medication may be beneficial. We examined whether these strategies have been adopted in five northern-European countries. Methods:, In 2003, a questionnaire concerning peri-operative anaesthetic routines in elective, open colonic cancer resection was sent to the chief anaesthesiologist in 258 digestive surgical centres in Scotland, the Netherlands, Denmark, Sweden and Norway. Results:, The response rate was 74% (n = 191). Although periods of pre-operative fasting up to 48 h were reported, most (> 85%) responders in all countries declared to adhere to guidelines for pre-operative fasting and oral clear liquids were permitted until 2,3 h before anaesthesia. Solid food was permitted up to 6,8 h prior to anaesthesia. In all countries more than 85% of the responders indicated that epidural anaesthesia was routinely used. Except for Denmark, long-acting benzodiazepines were still widely used. Short-acting anaesthetics were used in all countries except Scotland where isoflurane is the anaesthetic of choice. With the exception of Denmark, intravenous fluids were used unrestrictedly. Conclusion:, In northern Europe, most anaesthesiologists adhere to evidence-based optimal management strategies on pre-operative fasting, thoracic epidurals and short-acting anaesthetics. However, premedication with longer-acting agents is still common. Avoidance of fluid overload has not yet found its way into daily practice. This may leave patients undergoing elective colonic surgery at risk of oversedation and excessive fluid administration with potential adverse effects on surgical outcome. [source] Avoidance of Phrasal Verbs: The Case of Chinese Learners of EnglishLANGUAGE LEARNING, Issue 2 2004Yan Liao This study investigates the avoidance of English phrasal verbs by Chinese learners. Six groups of Chinese learners (intermediate and advanced; a total of 70) took one of 3 tests (multiple-choice, translation, or recall), which included literal and figurative phrasal verbs, while 15 native speakers took the multiple-choice test. The results show that 3 factors (proficiency level, phrasal- verb type, and test type) affect learners' avoidance of phrasal verbs. The authors speculate that the differences between first and second languages and the semantic difficulty of phrasal verbs may be reasons for the learners' avoidance. Incorporating the findings of 3 previous studies, this study claims that learners' phrasal-verb avoidance behavior is a manifestation of interlanguage development.
