Dopamine and Effort-Based Decision Making
Directory of Open Access Journals (Sweden)

Full Text Available Motivational theories of choice focus on the influence of goal values and strength of reinforcement to explain behavior. By contrast relatively little is known concerning how the cost of an action, such as effort expended, contributes to a decision to act. Effort-based decision making addresses how we make an action choice based on an integration of action and goal values. Here we review behavioral and neurobiological data regarding the representation of effort as action cost, and how this impacts on decision making. Although organisms expend effort to obtain a desired reward there is a striking sensitivity to the amount of effort required, such that the net preference for an action decreases as effort cost increases. We discuss the contribution of the neurotransmitter dopamine (DA towards overcoming response costs and in enhancing an animal’s motivation towards effortful actions. We also consider the contribution of brain structures, including the basal ganglia (BG and anterior cingulate cortex (ACC, in the internal generation of action involving a translation of reward expectation into effortful action.

Effort-Based Decision-Making in Schizophrenia.
Culbreth, Adam J; Moran, Erin K; Barch, Deanna M
2018-08-01
Motivational impairment has long been associated with schizophrenia but the underlying mechanisms are not clearly understood. Recently, a small but growing literature has suggested that aberrant effort-based decision-making may be a potential contributory mechanism for motivational impairments in psychosis. Specifically, multiple reports have consistently demonstrated that individuals with schizophrenia are less willing than healthy controls to expend effort to obtain rewards. Further, this effort-based decision-making deficit has been shown to correlate with severity of negative symptoms and level of functioning, in many but not all studies. In the current review, we summarize this literature and discuss several factors that may underlie aberrant effort-based decision-making in schizophrenia.

Effort-based decision making requires one to decide how much effort to expend for a certain amount of reward. As the amount of reward goes up most people are willing to exert more effort. This relationship between reward level and effort expenditure can be measured in specialized performance-based tasks that have only recently been applied to schizophrenia. Such tasks provide a way to measure objectively motivational deficits in schizophrenia, which now are only assessed with clinical interviews of negative symptoms. The articles in this theme provide reviews of the relevant animal and human literatures (first 2 articles), and then a psychometric evaluation of 5 effort-based decision making paradigms (last 2 articles). This theme section is intended to stimulate interest in this emerging area among basic scientists developing paradigms for preclinical studies, human experimentalists trying to disentangle factors that contribute to performance on effort-based tasks, and investigators looking for objective endpoints for clinical trials of negative symptoms in schizophrenia. © The Author 2015.

Vicarious Effort-Based Decision-Making in Autism Spectrum Disorders.
Mosner, Maya G; Kinard, Jessica L; McWeeny, Sean; Shah, Jasmine S; Markiewitz, Nathan D; Damiano-Goodwin, Cara R; Burchinal, Margaret R; Rutherford, Helena J V; Greene, Rachel K; Treadway, Michael T; Dichter, Gabriel S

This study investigated vicarious effort-based decision-making in 50 adolescents with autism spectrum disorders (ASD) compared to 32 controls using the Effort Expenditure for Rewards Task. Participants made choices to win money for themselves or for another person. When choosing for themselves, the ASD group exhibited relatively similar patterns of effort-based decision-making across reward parameters. However, when choosing for another person, the ASD group demonstrated relatively decreased sensitivity to reward magnitude, particularly in the high magnitude condition. Finally, patterns of responding in the ASD group were related to individual differences in consummatory pleasure capacity. These findings indicate atypical vicarious effort-based decision-making in ASD and more broadly add to the growing body of literature addressing social reward processing deficits in ASD.

Perceived effort for motor control and decision-making.
Directory of Open Access Journals (Sweden)
Ignasi Cos

Full Text Available How effort is internally quantified and how it influences both movement generation and decisions between potential movements are 2 difficult questions to answer. Physical costs are known to influence motor control and decision-making, yet we lack a general, principled characterization of how the perception of effort operates across tasks and conditions. Morel and colleagues introduce an insightful approach to that end, assessing effort indifference points and presenting a quadratic law between perceived effort and force production.

Full Text Available When deciding between alternative options, a rational agent chooses on the basis of the desirability of each outcome, including associated costs. As different options typically result in different actions, the effort associated with each action is an essential cost parameter. How do humans discount physical effort when deciding between movements? We used an action-selection task to characterize how subjective effort depends on the parameters of arm transport movements and controlled for potential confounding factors such as delay discounting and performance. First, by repeatedly asking subjects to choose between 2 arm movements of different amplitudes or durations, performed against different levels of force, we identified parameter combinations that subjects experienced as identical in effort (isoeffort curves. Movements with a long duration were judged more effortful than short-duration movements against the same force, while movement amplitudes did not influence effort. Biomechanics of the movements also affected effort, as movements towards the body midline were preferred to movements away from it. Second, by introducing movement repetitions, we further determined that the cost function for choosing between effortful movements had a quadratic relationship with force, while choices were made on the basis of the logarithm of these costs. Our results show that effort-based action selection during reaching cannot easily be explained by metabolic costs. Instead, force-loaded reaches, a widely occurring natural behavior, imposed an effort cost for decision making similar to cost functions in motor control. Our results thereby support the idea that motor control and economic choice are governed by partly overlapping optimization principles.

Effort-Based Decision Making: A Novel Approach for Assessing Motivation in Schizophrenia.
Green, Michael F; Horan, William P; Barch, Deanna M; Gold, James M
2015-09-01
Because negative symptoms, including motivational deficits, are a critical unmet need in schizophrenia, there are many ongoing efforts to develop new pharmacological and psychosocial interventions for these impairments. A common challenge of these studies involves how to evaluate and select optimal endpoints. Currently, all studies of negative symptoms in schizophrenia depend on ratings from clinician-conducted interviews. Effort-based decision-making tasks may provide a more objective, and perhaps more sensitive, endpoint for trials of motivational negative symptoms. These tasks assess how much effort a person is willing to exert for a given level of reward. This area has been well-studied with animal models of effort and motivation, and effort-based decision-making tasks have been adapted for use in humans. Very recently, several studies have examined physical and cognitive types of effort-based decision-making tasks in cross-sectional studies of schizophrenia, providing evidence for effort-related impairment in this illness. This article covers the theoretical background on effort-based decision-making tasks to provide a context for the subsequent articles in this theme section. In addition, we review the existing literature of studies using these tasks in schizophrenia, consider some practical challenges in adapting them for use in clinical trials in schizophrenia, and discuss interpretive challenges that are central to these types of tasks. © The Author 2015.

Activation of the cannabinoid system in the nucleus accumbens affects effort-based decision making.
Fatahi, Zahra; Haghparast, Abbas
2018-02-01
Effort-based decision making addresses how we make an action choice based on an integration of action and goal values. The nucleus accumbens (NAc) is implicated in allowing an animal to overcome effort constraints to obtain greater benefits, and it has been previously shown that cannabis derivatives may affect such processes. Therefore, in this study, we intend to evaluate the involvement of the cannabinoid system in the entire NAc on effort-based decision making. Rats were trained in a T-maze cost-benefit decision making the task in which they could choose either to climb a barrier to obtain a large reward in one arm or run into the other arm without a barrier to obtaining a small reward. Following training, the animals were bilaterally implanted with guide cannulae in the NAc. On test day, rats received cannabinoid agonist (Win 55,212-2; 2, 10 and 50μM) and/or antagonist (AM251; 45μM), afterward percentage of large reward choice and latency of reward attainment were investigated. Results revealed that the administration of cannabinoid agonist led to decrease of large reward choice percentage such that the animals preferred to receive a small reward with low effort instead of receiving a large reward with high effort. The administration of antagonist solely did not affect effort-based decision making, but did attenuate the Win 55,212-2-induced impairments in effort allocation. In agonist-treated animals, the latency of reward collection increased. Moreover, when the effort was equated on both arms, the animals returned to choosing large reward showing that obtained results were not caused by spatial memory impairment. Our finding suggested that activation of the cannabinoid system in the NAc impaired effort-based decision making and led to rats were less willing to invest the physical effort to gain large reward.

Unwillingness to expend more effort to pursue high value rewards has been associated with motivational anhedonia in schizophrenia (SCZ) and abnormal dopamine activity in the nucleus accumbens (NAcc). The authors hypothesized that dysfunction of the NAcc and the associated forebrain regions are involved in the impaired effort expenditure decision-making of SCZ. A 2 (reward magnitude: low vs. high) × 3 (probability: 20% vs. 50% vs. 80%) event-related fMRI design in the effort-expenditure for reward task (EEfRT) was used to examine the neural response of 23 SCZ patients and 23 demographically matched control participants when the participants made effort expenditure decisions to pursue uncertain rewards. SCZ patients were significantly less likely to expend high level of effort in the medium (50%) and high (80%) probability conditions than healthy controls. The neural response in the NAcc, the posterior cingulate gyrus and the left medial frontal gyrus in SCZ patients were weaker than healthy controls and did not linearly increase with an increase in reward magnitude and probability. Moreover, NAcc activity was positively correlated with the willingness to expend high-level effort and concrete consummatory pleasure experience. NAcc and posterior cingulate dysfunctions in SCZ patients may be involved in their impaired effort expenditure decision-making. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Effortful semantic decision-making boosts memory performance in older adults.
Fu, Li; Maes, Joseph H R; Varma, Samarth; Kessels, Roy P C; Daselaar, Sander M
2017-04-01
A major concern in age-related cognitive decline is episodic memory (EM). Previous studies indicate that both resource and binding deficits contribute to EM decline. Environmental support by task manipulations encouraging stronger cognitive effort and deeper levels of processing may facilitate compensation for these two deficits. To clarify factors that can counteract age-related EM decline, we assessed effects of cognitive effort (four levels) and level of processing (LoP, shallow/deep) during encoding on subsequent retrieval. Young (YAs, N = 23) and older (OAs, N = 23) adults performed two incidental encoding tasks, deep/semantic and shallow/perceptual. Cognitive effort was manipulated by varying decision-making demands. EM performance, indexed by d-prime, was later tested using a recognition task. Results showed that regardless of LoP, increased cognitive effort caused higher d-primes in both age groups. Compared to YAs, OAs showed a lower d-prime after shallow encoding across all cognitive effort levels, and after deep encoding with low cognitive effort. Deep encoding with higher levels of cognitive effort completely eliminated these age differences. Our findings support an environmental-compensatory account of cognitive ageing and can have important therapeutic implications.

Challenges in Special Steel Making
Balachandran, G.
2018-02-01
Special bar quality [SBQ] is a long steel product where an assured quality is delivered by the steel mill to its customer. The bars have enhanced tolerance to higher stress application and it is demanded for specialised component making. The SBQ bars are sought for component making processing units such as closed die hot forging, hot extrusion, cold forging, machining, heat treatment, welding operations. The final component quality of the secondary processing units depends on the quality maintained at the steel maker end along with quality maintained at the fabricator end. Thus, quality control is ensured at every unit process stages. The various market segments catered to by SBQ steel segment is ever growing and is reviewed. Steel mills need adequate infrastructure and technological capability to make these higher quality steels. Some of the critical stages of processing SBQ and the critical quality maintenance parameters at the steel mill in the manufacture has been brought out.

Decision-making policies are subject to modulation by changing motivational states. However, so far, little is known about the neurochemical mechanisms that bridge motivational states with decision making. Here we examined whether dopamine (DA) in the nucleus accumbens core (AcbC) modulates the effects of motivational states on effort-based decision making. Using a cost-benefit T-maze task in rats, we examined the effects of AcbC DA depletions on effort-based decision making, in particular on the sensitivity of effort-based decision making to a shift from a hungry to a sated state. The results demonstrated that, relative to sham controls, rats with AcbC DA depletion in a hungry as well as in a sated state had a reduced preference for effortful but large-reward action. This finding provides further support for the notion that AcbC DA regulates how much effort to invest for rewards. Importantly, our results further revealed that effort-based decision making in lesioned rats, as in sham controls, was still sensitive to a shift from a hungry to a sated state; that is, their preferences for effortful large-reward actions became lower after a shift from a restricted to a free-feeding regimen. These finding indicate that AcbC DA is not necessarily involved in mediating the effects of a shift in motivational state on decision-making policies.

Acute stress activates numerous systems in a coordinated effort to promote homeostasis, and can exert differential effects on mnemonic and cognitive functions depending on a myriad of factors. Stress can alter different forms of cost/benefit decision-making, yet the mechanisms that drive these effects, remain unclear. In the present study, we probed how corticotropin-releasing factor (CRF) may contribute to stress-induced alterations in cost/benefit decision-making, using an task where well-trained rats chose between a low effort/low reward lever (LR; two pellets) and a high effort/high reward lever (HR; four pellets), with the effort requirement increasing over a session (2, 5, 10, and 20 presses). One-hour restraint stress markedly reduced preference for the HR option, but this effect was attenuated by infusions of the CRF antagonist, alpha-helical CRF. Conversely, central CRF infusion mimicked the effect of stress on decision-making, as well as increased decision latencies and reduced response vigor. CRF infusions did not alter preference for larger vs smaller rewards, but did reduce responding for food delivered on a progressive ratio, suggesting that these treatments may amplify perceived effort costs that may be required to obtain rewards. CRF infusions into the ventral tegmental area recapitulated the effect of central CRF treatment and restraint on choice behavior, suggesting that these effects may be mediated by perturbations in dopamine transmission. These findings highlight the involvement of CRF in regulating effort-related decisions and suggest that increased CRF activity may contribute to motivational impairments and abnormal decision-making associated with stress-related psychiatric disorders such as depression.

Distinct effects of apathy and dopamine on effort-based decision-making in Parkinson's disease.

Effort-based decision-making is a cognitive process crucial to normal motivated behaviour. Apathy is a common and disabling complication of Parkinson's disease, but its aetiology remains unclear. Intriguingly, the neural substrates associated with apathy also subserve effort-based decision-making in animal models and humans. Furthermore, the dopaminergic system plays a core role in motivating effortful behaviour for reward, and its dysfunction has been proposed to play a crucial role in the aetiology of apathy in Parkinson's disease. We hypothesized that disrupted effort-based decision-making underlies the syndrome of apathy in Parkinson's disease, and that this disruption may be modulated by the dopaminergic system. An effort-based decision-making task was administered to 39 patients with Parkinson's disease, with and without clinical apathy, ON and OFF their normal dopaminergic medications across two separate sessions, as well as 32 healthy age- and gender-matched controls. On a trial-by-trial basis, participants decided whether to accept or reject offers of monetary reward in return for exerting different levels of physical effort via handheld, individually calibrated dynamometers. Effort and reward were manipulated independently, such that offers spanned the full range of effort/reward combinations. Apathy was assessed using the Lille apathy rating scale. Motor effects of the dopamine manipulation were assessed using the Unified Parkinson's Disease Rating Scale part three motor score. The primary outcome variable was choice (accept/decline offer) analysed using a hierarchical generalized linear mixed effects model, and the vigour of squeeze (Newtons exerted above required force). Both apathy and dopamine depletion were associated with reduced acceptance of offers. However, these effects were driven by dissociable patterns of responding. While apathy was characterized by increased rejection of predominantly low reward offers, dopamine increased responding to

Full Text Available Abstract Background Efficient effort expenditure to obtain rewards is critical for optimal goal-directed behavior and learning. Clinical observation suggests that individuals with autism spectrum disorders (ASD may show dysregulated reward-based effort expenditure, but no behavioral study to date has assessed effort-based decision-making in ASD. Methods The current study compared a group of adults with ASD to a group of typically developing adults on the Effort Expenditure for Rewards Task (EEfRT, a behavioral measure of effort-based decision-making. In this task, participants were provided with the probability of receiving a monetary reward on a particular trial and asked to choose between either an “easy task” (less motoric effort for a small, stable reward or a “hard task” (greater motoric effort for a variable but consistently larger reward. Results Participants with ASD chose the hard task more frequently than did the control group, yet were less influenced by differences in reward value and probability than the control group. Additionally, effort-based decision-making was related to repetitive behavior symptoms across both groups. Conclusions These results suggest that individuals with ASD may be more willing to expend effort to obtain a monetary reward regardless of the reward contingencies. More broadly, results suggest that behavioral choices may be less influenced by information about reward contingencies in individuals with ASD. This atypical pattern of effort-based decision-making may be relevant for understanding the heightened reward motivation for circumscribed interests in ASD.

The role of cognitive effort in subjective reward devaluation and risky decision-making.
Apps, Matthew A J; Grima, Laura L; Manohar, Sanjay; Husain, Masud
2015-11-20
Motivation is underpinned by cost-benefit valuations where costs-such as physical effort or outcome risk-are subjectively weighed against available rewards. However, in many environments risks pertain not to the variance of outcomes, but to variance in the possible levels of effort required to obtain rewards (effort risks). Moreover, motivation is often guided by the extent to which cognitive-not physical-effort devalues rewards (effort discounting). Yet, very little is known about the mechanisms that underpin the influence of cognitive effort risks or discounting on motivation. We used two cost-benefit decision-making tasks to probe subjective sensitivity to cognitive effort (number of shifts of spatial attention) and to effort risks. Our results show that shifts of spatial attention when monitoring rapidly presented visual stimuli are perceived as effortful and devalue rewards. Additionally, most people are risk-averse, preferring safe, known amounts of effort over risky offers. However, there was no correlation between their effort and risk sensitivity. We show for the first time that people are averse to variance in the possible amount of cognitive effort to be exerted. These results suggest that cognitive effort sensitivity and risk sensitivity are underpinned by distinct psychological and neurobiological mechanisms.

Amotivational states and insufficient recruitment of mental effort have been observed in a variety of clinical populations, including depression, traumatic brain injury, post-traumatic stress disorder, and attention deficit hyperactivity disorder. Previous rodent models of effort-based decision making have utilized physical costs whereas human studies of effort are primarily cognitive in nature, and it is unclear whether the two types of effortful decision making are underpinned by the same neurobiological processes. We therefore designed a novel rat cognitive effort task (rCET) based on the 5-choice serial reaction time task, a well-validated measure of attention and impulsivity. Within each trial of the rCET, rats are given the choice between an easy or hard visuospatial discrimination, and successful hard trials are rewarded with double the number of sugar pellets. Similar to previous human studies, stable individual variation in choice behavior was observed, with 'workers' choosing hard trials significantly more than their 'slacker' counterparts. Whereas workers 'slacked off' in response to administration of amphetamine and caffeine, slackers 'worked harder' under amphetamine, but not caffeine. Conversely, these stimulants increased motor impulsivity in all animals. Ethanol did not affect animals' choice but invigorated behavior. In sum, we have shown for the first time that rats are differentially sensitive to cognitive effort when making decisions, independent of other processes such as impulsivity, and these baseline differences can influence the cognitive response to psychostimulants. Such findings could inform our understanding of impairments in effort-based decision making and contribute to treatment development.

Full Text Available Cost-benefit decision-making entails the process of evaluating potential actions according to the trade-off between the expected benefit (reward and the anticipated costs (effort. Recent research revealed that dopaminergic transmission within the fronto-striatal circuitry strongly modulates cost-benefit decision-making. Alterations within the dopaminergic fronto-striatal system have been associated with obesity, but little is known about cost-benefit decision-making differences in obese compared with lean individuals. With a newly developed experimental task we investigate obesity-associated alterations in cost-benefit decision-making, utilizing physical effort by handgrip-force exertion and both food and non-food rewards. We relate our behavioral findings to alterations in local grey matter volume assessed by structural MRI. Obese compared with lean subjects were less willing to engage in physical effort in particular for high-caloric sweet snack food. The amount of effort exertion was thereby negatively associated with subjects’ individual levels of chronic stress and punishment sensitivity. Further, self-reported body dissatisfaction negatively correlated with the willingness to invest effort for sweet snacks in obese men. On a structural level, obesity was associated with reductions in grey matter volume in bilateral prefrontal cortex. Nucleus accumbens volume positively correlated with task-induced implicit food craving. Our results challenge the common notion that obese individuals are willing to work harder to obtain high-caloric food and emphasize the need for further exploration of the underlying neural mechanisms regarding cost-benefit decision-making differences in obesity.

Effort-based decision-making paradigms are increasingly utilized to gain insight into the nature of motivation deficits. Research has shown associations between effort-based decision making and experiential negative symptoms; however, the associations are not consistent. The current study had two primary goals. First, we aimed to replicate previous findings of a deficit in effort-based decision making among individuals with schizophrenia on a test of cognitive effort. Second, in a large sample combined from the current and a previous study, we sought to examine the association between negative symptoms and effort by including the related construct of defeatist beliefs. The results replicated previous findings of impaired cognitive effort-based decision making in schizophrenia. Defeatist beliefs significantly moderated the association between negative symptoms and effort-based decision making such that there was a strong association between high negative symptoms and deficits in effort-based decision making, but only among participants with high levels of defeatist beliefs. Thus, our findings suggest the relationship between negative symptoms and effort performance may be understood by taking into account the role of defeatist beliefs, and finding that might explain discrepancies in previous studies.

The role of the striatum in effort-based decision-making in the absence of reward.
Schouppe, Nathalie; Demanet, Jelle; Boehler, Carsten N; Ridderinkhof, K Richard; Notebaert, Wim
2014-02-05
Decision-making involves weighing costs against benefits, for instance, in terms of the effort it takes to obtain a reward of a given magnitude. This evaluation process has been linked to the dorsal anterior cingulate cortex (dACC) and the striatum, with activation in these brain structures reflecting the discounting effect of effort on reward. Here, we investigate how cognitive effort influences neural choice processes in the absence of an extrinsic reward. Using functional magnetic resonance imaging in humans, we used an effort-based decision-making task in which participants were required to choose between two options for a subsequent flanker task that differed in the amount of cognitive effort. Cognitive effort was manipulated by varying the proportion of incongruent trials associated with each choice option. Choice-locked activation in the striatum was higher when participants chose voluntarily for the more effortful alternative but displayed the opposite trend on forced-choice trials. The dACC revealed a similar, yet only trend-level significant, activation pattern. Our results imply that activation levels in the striatum reflect a cost-benefit analysis, in which a balance is made between effort discounting and the intrinsic motivation to choose a cognitively challenging task. Moreover, our findings indicate that it matters whether this challenge is voluntarily chosen or externally imposed. As such, the present findings contrast with classical findings on effort discounting that found reductions in striatum activation for higher effort by finding enhancements of the same neural circuits when a cognitively challenging task is voluntarily selected and does not entail the danger of losing reward.

Personal success often necessitates expending greater effort for greater reward but, equally important, also requires judicious use of our limited cognitive resources (e.g., attention). Previous animal models have shown that the prelimbic (PL) and infralimbic (IL) regions of the prefrontal cortex (PFC) are not involved in (physical) effort-based choice, whereas human studies have demonstrated PFC contributions to (mental) effort. Here, we utilize the rat Cognitive Effort Task (rCET) to probe PFC's role in effort-based decision making. In the rCET, animals can choose either an easy trial, where the attentional demand is low but the reward (sugar) is small or a difficult trial on which both the attentional demand and reward are greater. Temporary inactivation of PL and IL decreased all animals' willingness to expend mental effort and increased animals' distractibility; PL inactivations more substantially affected performance (i.e., attention), whereas IL inactivations increased motor impulsivity. These data imply that the PFC contributes to attentional resources, and when these resources are diminished, animals shift their choice (via other brain regions) accordingly. Thus, one novel therapeutic approach to deficits in effort expenditure may be to focus on the resources that such decision making requires, rather than the decision-making process per se. © The Author 2015.

Personal success often requires the choice to expend greater effort for larger rewards, and deficits in such effortful decision making accompany a number of illnesses including depression, schizophrenia, and attention-deficit/hyperactivity disorder. Animal models have implicated brain regions such as the basolateral amygdala (BLA) and anterior cingulate cortex (ACC) in physical effort-based choice, but disentangling the unique contributions of these two regions has proven difficult, and effort demands in industrialized society are predominantly cognitive in nature. Here we utilize the rodent cognitive effort task (rCET), a modification of the five-choice serial reaction-time task, wherein animals can choose to expend greater visuospatial attention to obtain larger sucrose rewards. Temporary inactivation (via baclofen-muscimol) of BLA and ACC showed dissociable effects: BLA inactivation caused hard-working rats to 'slack off' and 'slacker' rats to work harder, whereas ACC inactivation caused all animals to reduce willingness to expend mental effort. Furthermore, BLA inactivation increased the time needed to make choices, whereas ACC inactivation increased motor impulsivity. These data illuminate unique contributions of BLA and ACC to effort-based decision making, and imply overlapping yet distinct circuitry for cognitive vs physical effort. Our understanding of effortful decision making may therefore require expanding our models beyond purely physical costs.

Effort-based decision making has strong conceptual links to the motivational disturbances that define a key subdomain of negative symptoms. However, the extent to which effort-based decision-making performance relates to negative symptoms, and other clinical and functionally important variables has yet to be systematically investigated. In 94 clinically stable outpatients with schizophrenia, we examined the external validity of 5 effort-based paradigms, including the Effort Expenditure for Rewards, Balloon Effort, Grip Strength Effort, Deck Choice Effort, and Perceptual Effort tasks. These tasks covered 3 types of effort: physical, cognitive, and perceptual. Correlations between effort related performance and 6 classes of variables were examined, including: (1) negative symptoms, (2) clinically rated motivation and community role functioning, (3) self-reported motivational traits, (4) neurocognition, (5) other psychiatric symptoms and clinical/demographic characteristics, and (6) subjective valuation of monetary rewards. Effort paradigms showed small to medium relationships to clinical ratings of negative symptoms, motivation, and functioning, with the pattern more consistent for some measures than others. They also showed small to medium relations with neurocognitive functioning, but were generally unrelated to other psychiatric symptoms, self-reported traits, antipsychotic medications, side effects, and subjective valuation of money. There were relatively strong interrelationships among the effort measures. In conjunction with findings from a companion psychometric article, all the paradigms warrant further consideration and development, and 2 show the strongest potential for clinical trial use at this juncture. © The Author 2015.

Negative symptoms and motivational deficits are prevalent features of schizophrenia, and represent robust predictors of real-world functional outcomes. The standard for assessment of these symptoms is clinical interview and severity ratings on standardized rating scales. In the present study we examined the psychometric properties of a performance-based measure of motivational deficits in patients with schizophrenia. Ninety-seven patients with schizophrenia were included in this investigation. Patients' willingness to expend effort for reward (i.e., motivation) was evaluated using an effort-based decision making paradigm where participants chose over a series of trials whether to expend a greater amount of effort for a larger monetary reward versus less effort for a smaller reward. Effort performance was evaluated twice, separated by a two-week interval. Patients with schizophrenia opted to expend greater effort for trials with higher reward value and greater likelihood of reward receipt. Patients did not find the task overly difficult and reported being motivated to perform well, underscoring the tolerability of the task for patients. Test-retest consistency was good and there was only minimal change in scores over time. Effort performance was not related to sociodemographic or clinical variables (e.g., positive symptoms); however, deficit syndrome patients exerted effort for reward at a significantly lower rate than nondeficit patients. The effort-based decision making task used in the present study represents an objective paradigm that can be used to evaluate motivational impairments in patients with schizophrenia. Such performance-based measures of motivation may also serve as viable endpoints in clinical trials. Copyright © 2015 Elsevier B.V. All rights reserved.

The objectives of this study are to study the participation of paddy farmers in the Special Effort program to increase paddy production, to study the level of household food security of paddy farmers, and to analyze the correlation between farmer participation and food security level of paddy farmers. The location was chosen purposively in Seputih Raman sub-district. The data were collected from December 2016 to February 2017. The population of this study was paddy farmers who participating in Special Effort program. The hypothesis was tested by using Spearman’s Rank correlation test. Farmer household’s food security was measured objectively based on the share of household’s food expenditure and subjectively based on the opinion, views, and attitudes or farmers’ opinions on food availability, food distribution, and household food consumption. This research showed that farmers’ participation in Special Effort program in Seputih Raman Sub Ditrict, Central Lampung Regency belonged to medium classification, household food security either objectively or subjectively was in food resistant condition of medium classification, and there was significant correlation between farmers’ participation and food security level of paddy farmer household.

Simulation and modeling efforts to support decision making in healthcare supply chain management.
AbuKhousa, Eman; Al-Jaroodi, Jameela; Lazarova-Molnar, Sanja; Mohamed, Nader
2014-01-01
Recently, most healthcare organizations focus their attention on reducing the cost of their supply chain management (SCM) by improving the decision making pertaining processes' efficiencies. The availability of products through healthcare SCM is often a matter of life or death to the patient; therefore, trial and error approaches are not an option in this environment. Simulation and modeling (SM) has been presented as an alternative approach for supply chain managers in healthcare organizations to test solutions and to support decision making processes associated with various SCM problems. This paper presents and analyzes past SM efforts to support decision making in healthcare SCM and identifies the key challenges associated with healthcare SCM modeling. We also present and discuss emerging technologies to meet these challenges.

Cost-benefit decision-making entails the process of evaluating potential actions according to the trade-off between the expected reward (benefit) and the anticipated effort (costs). Recent research revealed that dopaminergic transmission within the fronto-striatal circuitry strongly modulates cost-benefit decision-making. Alterations within the dopaminergic fronto-striatal system have been associated with obesity, but little is known about cost-benefit decision-making differences in obese com...

Successful decision making often requires weighing a given option's costs against its associated benefits, an ability that appears perturbed in virtually every severe mental illness. Animal models of such cost/benefit decision making overwhelmingly implicate mesolimbic dopamine in our willingness to exert effort for a larger reward. Until recently, however, animal models have invariably manipulated the degree of physical effort, whereas human studies of effort have primarily relied on cognitive costs. Dopamine's relationship to cognitive effort has not been directly examined, nor has the relationship between individuals' willingness to expend mental versus physical effort. It is therefore unclear whether willingness to work hard in one domain corresponds to willingness in the other. Here we utilize a rat cognitive effort task (rCET), wherein animals can choose to allocate greater visuospatial attention for a greater reward, and a previously established physical effort-discounting task (EDT) to examine dopaminergic and noradrenergic contributions to effort. The dopamine antagonists eticlopride and SCH23390 each decreased willingness to exert physical effort on the EDT; these drugs had no effect on willingness to exert mental effort for the rCET. Preference for the high effort option correlated across the two tasks, although this effect was transient. These results suggest that dopamine is only minimally involved in cost/benefit decision making with cognitive effort costs. The constructs of mental and physical effort may therefore comprise overlapping, but distinct, circuitry, and therapeutic interventions that prove efficacious in one effort domain may not be beneficial in another.

A model of reward- and effort-based optimal decision making and motor control.
Directory of Open Access Journals (Sweden)
Lionel Rigoux
Full Text Available Costs (e.g. energetic expenditure and benefits (e.g. food are central determinants of behavior. In ecology and economics, they are combined to form a utility function which is maximized to guide choices. This principle is widely used in neuroscience as a normative model of decision and action, but current versions of this model fail to consider how decisions are actually converted into actions (i.e. the formation of trajectories. Here, we describe an approach where decision making and motor control are optimal, iterative processes derived from the maximization of the discounted, weighted difference between expected rewards and foreseeable motor efforts. The model accounts for decision making in cost/benefit situations, and detailed characteristics of control and goal tracking in realistic motor tasks. As a normative construction, the model is relevant to address the neural bases and pathological aspects of decision making and motor control.

The area of decision making has much to offer in our effort to understand special populations. This pilot study is an example of just such a project, where we illustrate how traditional decision making tools and tasks can be used to uncover strengths and weaknesses within a growing population of young adults with autism. In this pilot project we extended accounts of autistic behavior such as those derived from "theory of mind" to predict key components of decision making in high-functioning young adults on the autism spectrum. A battery of tests was administered to 15 high-functioning college students with autism spectrum disorder (ASD), focusing on decision making competence (DMC) and other aspects of decision making related to known deficits associated with autism. Data from this group were compared to data from unselected college students receiving the same measures. First, as a test of a key social deficit associated with autism, the target group scored much lower on the Empathy Quotient scale. Traditional elements of decision making competency such as Numeracy and application of decision rules were comparable across groups. However, there were differences in thinking style, with the ASD group showing lesser ability and engagement in intuitive thinking, and they showed lower levels of risk taking. For comparisons within the ASD group, autobiographical reports concerning individual lifestyles and outcomes were used to derive a scale of Social Functioning. The lowest scoring individuals showed the lowest levels of intuitive thinking, the lowest perceived levels of others' endorsement of socially undesirable behaviors, and the lowest ability to discriminate between "good" and "bad" risks. Results are discussed in terms of interventions that might aid high-functioning young adults with ASD in their everyday decision making.

Anhedonia is a hallmark symptom of major depressive disorder (MDD). Preliminary findings suggest that anhedonia is characterized by reduced reward anticipation and motivation of obtaining reward. However, relatively little is known about reward-based decision-making in depression. We tested the hypothesis that anhedonia in MDD may reflect specific impairments in motivation on reward-based decision-making and the deficits might be associated with depressive symptoms severity. In study 1, individuals with and without depressive symptoms performed the modified version of the Effort Expenditure for Rewards Task (EEfRT), a behavioral measure of cost/benefit decision-making. In study 2, MDD patients, remitted MDD patients and healthy controls were recruited for the same procedures. We found evidence for decreased willingness to make effort for rewards among individuals with subsyndromal depression; the effect was amplified in MDD patients, but dissipated in patients with remitted depression. We also found that reduced anticipatory and consummatory pleasure predicted decreased willingness to expend efforts to obtain rewards in MDD patients. For individuals with subsyndromal depression, the impairments were correlated with anticipatory anhedonia but not consummatory anhedonia. These data offer novel evidence that motivational deficits in MDD are correlated with depression severity and predicted by self-reported anhedonia. Copyright © 2014 Elsevier Ireland Ltd.

Virtual special issues: A new outreach effort from The Journal of Magnetic Resonance
Frydman, Lucio
2017-01-01
The Journal of Magnetic Resonance (JMR) prides itself in the quality of its publications. JMR has seen ground-breaking concepts appear in its pages, and literally whole sub-fields have sprung up from ideas published in its articles, equations and data. The search for original papers arising from you, the magnetic resonance expert, user, contributor and reader, was and remains the Journal's raison d'etre. This bottom-up approach seeks to give an outlet to contributions from all areas of magnetic resonance, while keeping the vibrancy, depth and ingenuity that have characterized our field and our Journal for nearly fifty years. While our ambition to be a forum for all matters concerning NMR, MRI, EPR and NQR -principles and applications, science and engineering, solids and liquids, physics and chemistry- lies at the core of our editorial spirit, it also raises a paradoxical situation. The variety of topics that magnetic resonance has given origin to and that JMR intends to cover, coupled with the multiplication of journals and the diversification in publication media formats, pose severe challenges to the scientist trying to keep abreast of the latest developments in our field. In order to deal with such challenge we are hereby launching, in partnership with Elsevier, a new effort: the Virtual Special Issue (VSI). Convinced that our papers contain excellent science that may go under-noticed in the short term, VSIs seek to highlight recent original JMR publications within the context of a relatively focused area of magnetic resonance. To do so the editorial team -working together with the magnetic resonance community at large- seeks to identify a thematic goal represented by JMR, and compile on its basis a homogeneous monograph relying on papers that have been recently published or accepted in the Journal. In order to bring these VSIs to our constituency we have designed a special workflow for these selected papers: while these publications will keep their original doi

Quantifying motivation with effort-based decision-making paradigms in health and disease.
Chong, T T-J; Bonnelle, V; Husain, M
2016-01-01
Motivation can be characterized as a series of cost-benefit valuations, in which we weigh the amount of effort we are willing to expend (the cost of an action) in return for particular rewards (its benefits). Human motivation has traditionally been measured with self-report and questionnaire-based tools, but an inherent limitation of these methods is that they are unable to provide a mechanistic explanation of the processes underlying motivated behavior. A major goal of current research is to quantify motivation objectively with effort-based decision-making paradigms, by drawing on a rich literature from nonhuman animals. Here, we review this approach by considering the development of these paradigms in the laboratory setting over the last three decades, and their more recent translation to understanding choice behavior in humans. A strength of this effort-based approach to motivation is that it is capable of capturing the wide range of individual differences, and offers the potential to dissect motivation into its component elements, thus providing the basis for more accurate taxonomic classifications. Clinically, modeling approaches might provide greater sensitivity and specificity to diagnosing disorders of motivation, for example, in being able to detect subclinical disorders of motivation, or distinguish a disorder of motivation from related but separate syndromes, such as depression. Despite the great potential in applying effort-based paradigms to index human motivation, we discuss several caveats to interpreting current and future studies, and the challenges in translating these approaches to the clinical setting. © 2016 Elsevier B.V.

Rats chronically infected with protozoan Toxoplasma gondii exhibit greater delay aversion in an inter-temporal task. Moreover T. gondii infection also results in dendritic atrophy of basolateral amygdala neurons. Basolateral amygdala is reported to bias decision making towards greater effortful alternatives. In this context, we report that T. gondii increases effort aversion in infected male rats. This host-parasite association has been widely studied in the context of loss of innate fear in the infected males. It is suggested that reduced fear towards predators reflects a parasitic behavioral manipulation to enhance trophic transmission of T. gondii. Observations reported here extend this paradigm away from a monolithic change in fear and towards a multi-dimensional change in decision making. Copyright © 2016 Elsevier Inc. All rights reserved.

This study fills a gap in the literature by exploring the utility of contemporary courtroom theoretical frameworks-uncertainty avoidance, causal attribution, and focal concerns-for explaining decision-making in specialized domestic violence courts. Using data from two specialized domestic violence courts, this study explores the predictors of prosecutorial and judicial decision-making and the extent to which these factors are congruent with theoretical frameworks often used in studies of court processing. Findings suggest that these theoretical frameworks only partially help explain decision-making in the courts under study.

Special education and occupational therapy: making the relationship work.
Coutinho, M J; Hunter, D L
1988-11-01
Working as an occupational therapist in publicly funded schools requires a variety of skills. These skills include assessing the needs of children, serving as a member of the multidisciplinary team, developing individualized education program (IEP) goals and objectives in conjunction with other team members, providing services, and coordinating efforts with parents, teachers, and administrators. To fulfill these responsibilities, occupational therapists must have a comprehensive understanding of the complex federal and state laws that mandate the provision of special education and related services. Therefore, the purposes of this article are (a) to describe the legal framework within which decisions are made to provide occupational therapy to students in publicly funded school programs and (b) to highlight the knowledge and skills occupational therapists need to work effectively in schools with teachers, administrators, and parents.

The Effort Paradox: Effort Is Both Costly and Valued.
Inzlicht, Michael; Shenhav, Amitai; Olivola, Christopher Y
2018-04-01
According to prominent models in cognitive psychology, neuroscience, and economics, effort (be it physical or mental) is costly: when given a choice, humans and non-human animals alike tend to avoid effort. Here, we suggest that the opposite is also true and review extensive evidence that effort can also add value. Not only can the same outcomes be more rewarding if we apply more (not less) effort, sometimes we select options precisely because they require effort. Given the increasing recognition of effort's role in motivation, cognitive control, and value-based decision-making, considering this neglected side of effort will not only improve formal computational models, but also provide clues about how to promote sustained mental effort across time.

Motivational impairments are a core feature of schizophrenia and although there are numerous reports studying this feature using clinical rating scales, objective behavioural assessments are lacking. Here, we use a translational paradigm to measure incentive motivation in individuals with schizophrenia. Sixteen stable outpatients with schizophrenia and sixteen matched healthy controls completed a modified version of the Effort Expenditure for Rewards Task that accounts for differences in motoric ability. Briefly, subjects were presented with a series of trials where they may choose to expend a greater amount of effort for a larger monetary reward versus less effort for a smaller reward. Additionally, the probability of receiving money for a given trial was varied at 12%, 50% and 88%. Clinical and other reward-related variables were also evaluated. Patients opted to expend greater effort significantly less than controls for trials of high, but uncertain (i.e. 50% and 88% probability) incentive value, which was related to amotivation and neurocognitive deficits. Other abnormalities were also noted but were related to different clinical variables such as impulsivity (low reward and 12% probability). These motivational deficits were not due to group differences in reward learning, reward valuation or hedonic capacity. Our findings offer novel support for incentive motivation deficits in schizophrenia. Clinical amotivation is associated with impairments in the computation of effort during cost-benefit decision-making. This objective translational paradigm may guide future investigations of the neural circuitry underlying these motivational impairments. Copyright © 2013 Elsevier Ltd. All rights reserved.

Functional specialization of the primate frontal cortex during decision making.
Lee, Daeyeol; Rushworth, Matthew F S; Walton, Mark E; Watanabe, Masataka; Sakagami, Masamichi
2007-08-01
Economic theories of decision making are based on the principle of utility maximization, and reinforcement-learning theory provides computational algorithms that can be used to estimate the overall reward expected from alternative choices. These formal models not only account for a large range of behavioral observations in human and animal decision makers, but also provide useful tools for investigating the neural basis of decision making. Nevertheless, in reality, decision makers must combine different types of information about the costs and benefits associated with each available option, such as the quality and quantity of expected reward and required work. In this article, we put forward the hypothesis that different subdivisions of the primate frontal cortex may be specialized to focus on different aspects of dynamic decision-making processes. In this hypothesis, the lateral prefrontal cortex is primarily involved in maintaining the state representation necessary to identify optimal actions in a given environment. In contrast, the orbitofrontal cortex and the anterior cingulate cortex might be primarily involved in encoding and updating the utilities associated with different sensory stimuli and alternative actions, respectively. These cortical areas are also likely to contribute to decision making in a social context.

Impairments in willingness to exert effort contribute to the motivational deficits characteristic of the negative symptoms of schizophrenia. The current study evaluated the psychometric properties of 5 new or adapted paradigms to determine their suitability for use in clinical trials of schizophrenia. This study included 94 clinically stable participants with schizophrenia and 40 healthy controls. The effort-based decision-making battery was administered twice to the schizophrenia group (baseline, 4-week retest) and once to the control group. The 5 paradigms included 1 that assesses cognitive effort, 1 perceptual effort, and 3 that assess physical effort. Each paradigm was evaluated on (1) patient vs healthy control group differences, (2) test-retest reliability, (3) utility as a repeated measure (ie, practice effects), and (4) tolerability. The 5 paradigms showed varying psychometric strengths and weaknesses. The Effort Expenditure for Rewards Task showed the best reliability and utility as a repeated measure, while the Grip Effort Task had significant patient-control group differences, and superior tolerability and administration duration. The other paradigms showed weaker psychometric characteristics in their current forms. These findings highlight challenges in adapting effort and motivation paradigms for use in clinical trials.

Full Text Available Behavioral activation is a fundamental feature of motivation, and organisms frequently make effort-related decisions based upon evaluations of reinforcement value and response costs. Furthermore, people with major depression and other disorders often show anergia, psychomotor retardation, fatigue, and alterations in effort-related decision making. Tasks measuring effort-based decision making can be used as animal models of the motivational symptoms of depression, and the present studies characterized the effort-related effects of the vesicular monoamine transport (VMAT-2 inhibitor tetrabenazine. Tetrabenazine induces depressive symptoms in humans, and also preferentially depletes dopamine (DA. Rats were assessed using a concurrent progressive ratio (PROG/chow feeding task, in which they can either lever press on a PROG schedule for preferred high-carbohydrate food, or approach and consume a less-preferred lab chow that is freely available in the chamber. Previous work has shown that the DA antagonist haloperidol reduced PROG work output on this task, but did not reduce chow intake, effects that differed substantially from those of reinforcer devaluation or appetite suppressant drugs. The present work demonstrated that tetrabenazine produced an effort-related shift in responding on the PROG/chow procedure, reducing lever presses, highest ratio achieved and time spent responding, but not reducing chow intake. Similar effects were produced by administration of the subtype selective DA antagonists ecopipam (D1 and eticlopride (D2, but not by the cannabinoid CB1 receptor neutral antagonist and putative appetite suppressant AM 4413, which suppressed both lever pressing and chow intake. The adenosine A2A antagonist MSX-3, the antidepressant and catecholamine uptake inhibitor bupropion, and the MAO-B inhibitor deprenyl, all reversed the impairments induced by tetrabenazine.

The standard view in biology is that all animals, from bumblebees to human beings, face a trade-off between speed and accuracy as they search for resources and mates, and attempt to avoid predators. For example, the more time a forager spends out of cover gathering information about potential food sources the more likely it is to make accurate decisions about which sources are most rewarding. However, when the cost of time spent out of cover rises (e.g. in the presence of a predator) the optimal strategy is for the forager to spend less time gathering information and to accept a corresponding decline in the accuracy of its decisions. We suggest that this familiar picture is missing a crucial dimension: the amount of effort an animal expends on gathering information in each unit of time. This is important because an animal that can respond to changing time costs by modulating its level of effort per-unit-time does not have to accept the same decrease in accuracy that an animal limited to a simple speed-accuracy trade-off must bear in the same situation. Instead, it can direct additional effort towards (i) reducing the frequency of perceptual errors in the samples it gathers or (ii) increasing the number of samples it gathers per-unit-time. Both of these have the effect of allowing it to gather more accurate information within a given period of time. We use a modified version of a canonical model of decision-making (the sequential probability ratio test) to show that this ability to substitute effort for time confers a fitness advantage in the face of changing time costs. We predict that the ability to modulate effort levels will therefore be widespread in nature, and we lay out testable predictions that could be used to detect adaptive modulation of effort levels in laboratory and field studies. Our understanding of decision-making in all species, including our own, will be improved by this more ecologically-complete picture of the three-way tradeoff between time

Human behavior is strongly driven by the pursuit of rewards. In daily life, however, benefits mostly come at a cost, often requiring that effort be exerted to obtain potential benefits. Medial PFC (MPFC) and dorsolateral PFC (DLPFC) are frequently implicated in the expectation of effortful control, showing increased activity as a function of predicted task difficulty. Such activity partially overlaps with expectation of reward and has been observed both during decision-making and during task preparation. Recently, novel computational frameworks have been developed to explain activity in these regions during cognitive control, based on the principle of prediction and prediction error (predicted response-outcome [PRO] model [Alexander, W. H., & Brown, J. W. Medial prefrontal cortex as an action-outcome predictor. Nature Neuroscience, 14, 1338-1344, 2011], hierarchical error representation [HER] model [Alexander, W. H., & Brown, J. W. Hierarchical error representation: A computational model of anterior cingulate and dorsolateral prefrontal cortex. Neural Computation, 27, 2354-2410, 2015]). Despite the broad explanatory power of these models, it is not clear whether they can also accommodate effects related to the expectation of effort observed in MPFC and DLPFC. Here, we propose a translation of these computational frameworks to the domain of effort-based behavior. First, we discuss how the PRO model, based on prediction error, can explain effort-related activity in MPFC, by reframing effort-based behavior in a predictive context. We propose that MPFC activity reflects monitoring of motivationally relevant variables (such as effort and reward), by coding expectations and discrepancies from such expectations. Moreover, we derive behavioral and neural model-based predictions for healthy controls and clinical populations with impairments of motivation. Second, we illustrate the possible translation to effort-based behavior of the HER model, an extended version of PRO

Motivation and effort in individuals with social anhedonia.
McCarthy, Julie M; Treadway, Michael T; Blanchard, Jack J
2015-06-01
It has been proposed that anhedonia may, in part, reflect difficulties in reward processing and effortful decision making. The current study aimed to replicate previous findings of effortful decision making deficits associated with elevated anhedonia and expand upon these findings by investigating whether these decision making deficits are specific to elevated social anhedonia or are also associated with elevated positive schizotypy characteristics. The current study compared controls (n=40) to individuals elevated on social anhedonia (n=30), and individuals elevated on perceptual aberration/magical ideation (n=30) on the Effort Expenditure for Rewards Task (EEfRT). Across groups, participants chose a higher proportion of hard tasks with increasing probability of reward and reward magnitude, demonstrating sensitivity to probability and reward values. Contrary to our expectations, when the probability of reward was most uncertain (50% probability), at low and medium reward values, the social anhedonia group demonstrated more effortful decision making than either individuals high in positive schizotypy or controls. The positive schizotypy group only differed from controls (making less effortful choices than controls) when reward probability was lowest (12%) and the magnitude of reward was the smallest. Our results suggest that social anhedonia is related to intact motivation and effort for monetary rewards, but that individuals with this characteristic display a unique and perhaps inefficient pattern of effort allocation when the probability of reward is most uncertain. Future research is needed to better understand effortful decision making and the processing of reward across a range of individual difference characteristics. Copyright © 2015 Elsevier B.V.

Dopamine is known to influence motivational processes, however the precise role of this neurotransmitter remains a contentious issue. In the current study we sought to further characterize dopamine signaling in reward-based decision-making and consummatory behavior in mice, via lateral ventricle infusion of the dopamine D2 receptor antagonist eticlopride. In Experiment 1, we examined effort-based decision-making, in which mice had a choice between one lever, where a single response led to the delivery of a low value reward (2% sucrose); and a second lever, which led to a higher value reward (20% sucrose) that gradually required more effort to obtain. As the response schedule for the high value reward became more strict, low dose (4μg in 0.5μl) central infusions of eticlopride biased preference away from the high value reward, and toward the lever that led to the low value reward. Similarly, a higher dose of eticlopride (8μg in 0.5μl) also disrupted choice responding for the high value reward, however it did so by increasing omissions. In Experiment 2, we assessed the effects of eticlopride on consumption of 20% sucrose. The antagonist led to a dose-dependent reduction in intake, and through an analysis of licking microstructure, it was revealed that this in part reflected a reduction in the motivation to engage in consummatory behavior, rather than alterations in the evaluation of the reward. These results suggest that disruptions in D2 receptor signaling reduce the willingness to engage in effortful operant responding and consumption of a desirable outcome. Copyright © 2016 Elsevier B.V.

Effortful semantic decision-making boosts memory performance in older adults
Fu, L.; Maes, J.H.R.; Varma, S.; Kessels, R.P.C.; Daselaar, S.M.
2017-01-01
A major concern in age-related cognitive decline is episodic memory (EM). Previous studies indicate that both resource and binding deficits contribute to EM decline. Environmental support by task manipulations encouraging stronger cognitive effort and deeper levels of processing may facilitate compensation for these two deficits. To clarify factors that can counteract age-related EM decline, we assessed effects of cognitive effort (four levels) and level of processing (LoP, shallow/deep) duri...

Successful decision making in our daily lives requires weighing an option's costs against its associated benefits. The neuromodulator acetylcholine underlies both the etiology and treatment of a number of illnesses in which decision making is perturbed, including Alzheimer's disease, attention-deficit/hyperactivity disorder, and schizophrenia. Nicotine acts on the cholinergic system and has been touted as a cognitive enhancer by both smokers and some researchers for its attention-boosting effects; however, it is unclear whether treatments that have a beneficial effect on attention would also have a beneficial effect on decision making. Here we utilize the rodent Cognitive Effort Task (rCET), wherein animals can choose to allocate greater visuospatial attention for a greater reward, to examine cholinergic contributions to both attentional performance and choice based on attentional demand. Following the establishment of baseline behavior, four drug challenges were administered: nicotine, mecamylamine, scopolamine, and oxotremorine (saline plus three doses for each). As per previous rCET studies, animals were divided by their baseline preferences, with "worker" rats choosing high-effort/high-reward options more than their "slacker" counterparts. Nicotine caused slackers to choose even fewer high-effort trials than at baseline, but had no effect on workers' choice. Despite slackers' decreased willingness to expend effort, nicotine improved their attentional performance on the task. Nicotine also increased measures of motor impulsivity in all animals. In contrast, scopolamine decreased animals' choice of high-effort trials, especially for workers, while oxotremorine decreased motor impulsivity for all animals. In sum, the cholinergic system appears to contribute to decision making, and in part these contributions can be understood as a function of individual differences. While nicotine has been considered as a cognitive enhancer, these data suggest that its modest

I endeavor to make it: effort increases valuation of subsequent monetary reward.
Ma, Qingguo; Meng, Liang; Wang, Lei; Shen, Qiang
2014-03-15
Although it is commonly accepted that the amount of effort we put into accomplishing a task would exert an influence on subsequent reward processing and outcome evaluation, whether effort is incorporated as a cost or it would increase the valuation of concomitant reward is still under debate. In this study, EEGs were recorded while subjects performed calculation tasks that required different amount of effort, correct responses of which were followed by either no reward or fixed compensation. Results showed that high effort induced larger differentiated FRN responses to the reward and non-reward discrepancy across two experimental conditions. Furthermore, P300 manifested valence effect during reward feedback, with more positive amplitudes for reward than for non-reward only in the high effort condition. These results suggest that effort might increase subjective evaluation toward subsequent reward. Copyright © 2013 Elsevier B.V. All rights reserved.

[Limitation of the therapeutic effort].
Herreros, B; Palacios, G; Pacho, E
2012-03-01
The limitation of the therapeutic effort (LTE) consists in not applying extraordinary or disproportionate measures for therapeutic purposes that are proposed for a patient with poor life prognosis and/or poor quality of life. There are two types. The first is to not initiate certain measures or to withdraw them when they are established. A decision of the LTE should be based on some rigorous criteria, so that we make the following proposal. First, it is necessary to know the most relevant details of the case to make a decision: the preferences of the patient, the preferences of the family when pertinent, the prognosis (severity), the quality of life and distribution of the limited resources. After, the decision should be made. In this phase, participatory deliberation should be established to clarify the end of the intervention. Finally, if it is decided to perform an LTE, it should be decided how to do it. Special procedures, disproportionate measures, that are useless and vain should not be initiated for the therapeutic objective designed (withdraw them if they have been established). When it has been decided to treat a condition (interim measures), the treatment should be maintained. This complex phase may need stratification of he measures. Finally, the necessary palliative measures should be established. Copyright © 2011 Elsevier España, S.L. All rights reserved.

The Role of Cognitive Effort in Framing Effects
Krzysztof Przybyszewski; Dorota Rutkowska
2013-01-01
Framing effects are a common bias in people making risky decisions. The account for this bias is found in the loss aversion derived from Prospect Theory. Most often in the decision making literature this is the effortful processes that are claimed to reduce framing effects in risky choice tasks i.e. investing of mental effort should de-bias the decision makers. However, in goal framing studies, effortful mental processes may produce those effects. In our experiment participants were primed wi...

Cognitive effort: A neuroeconomic approach
Braver, Todd S.
2015-01-01
Cognitive effort has been implicated in numerous theories regarding normal and aberrant behavior and the physiological response to engagement with demanding tasks. Yet, despite broad interest, no unifying, operational definition of cognitive effort itself has been proposed. Here, we argue that the most intuitive and epistemologically valuable treatment is in terms of effort-based decision-making, and advocate a neuroeconomics-focused research strategy. We first outline psychological and neuroscientific theories of cognitive effort. Then we describe the benefits of a neuroeconomic research strategy, highlighting how it affords greater inferential traction than do traditional markers of cognitive effort, including self-reports and physiologic markers of autonomic arousal. Finally, we sketch a future series of studies that can leverage the full potential of the neuroeconomic approach toward understanding the cognitive and neural mechanisms that give rise to phenomenal, subjective cognitive effort.

We hypothesize that the reverse effect is also true, and investigate changes in passion as an outcome of effort. Based on theories of self-regulation and self-perception, we hypothesize that making new venture progress and free choice are two factors that help to explain why and under which conditions entrepreneurial effort affects entrepreneurial passion.

Solar Flare Prediction Science-to-Operations: the ESA/SSA SWE A-EFFort Service
Georgoulis, Manolis K.; Tziotziou, Konstantinos; Themelis, Konstantinos; Magiati, Margarita; Angelopoulou, Georgia
2016-07-01
We attempt a synoptical overview of the scientific origins of the Athens Effective Solar Flare Forecasting (A-EFFort) utility and the actions taken toward transitioning it into a pre-operational service of ESA's Space Situational Awareness (SSA) Programme. The preferred method for solar flare prediction, as well as key efforts to make it function in a fully automated environment by coupling calculations with near-realtime data-downloading protocols (from the Solar Dynamics Observatory [SDO] mission), pattern recognition (solar active-region identification) and optimization (magnetic connectivity by simulated annealing) will be highlighted. In addition, the entire validation process of the service will be described, with its results presented. We will conclude by stressing the need for across-the-board efforts and synergistic work in order to bring science of potentially limited/restricted interest into realizing a much broader impact and serving the best public interests. The above presentation was partially supported by the ESA/SSA SWE A-EFFort project, ESA Contract No. 4000111994/14/D/MRP. Special thanks go to the ESA Project Officers R. Keil, A. Glover, and J.-P.

Two experiments investigate the influence of goal and implementation intentions on effort mobilization during task performance. Although numerous studies have demonstrated the beneficial effects of setting goals and making plans on performance, the effects of goals and plans on effort-related cardiac activity and especially the cardiac preejection period (PEP) during goal striving have not yet been addressed. According to the Motivational Intensity Theory, participants should increase effort mobilization proportionally to task difficulty as long as success is possible and justified. Forming goals and making plans should allow for reduced effort mobilization when participants perform an easy task. However, when the task is difficult, goals and plans should differ in their effect on effort mobilization. Participants who set goals should disengage, whereas participants who made if-then plans should stay in the field showing high effort mobilization during task performance. As expected, using an easy task in Experiment 1, we observed a lower cardiac PEP in both the implementation intention and the goal intention condition than in the control condition. In Experiment 2, we varied task difficulty and demonstrated that while participants with a mere goal intention disengaged from difficult tasks, participants with an implementation intention increased effort mobilization proportionally with task difficulty. These findings demonstrate the influence of goal striving strategies (i.e., mere goals vs. if-then plans) on effort mobilization during task performance. Copyright © 2016 Elsevier B.V.

Coordinating a Supply Chain with a Loss-Averse Retailer and Effort Dependent Demand
Li, Liying
2014-01-01
This study investigates the channel coordination issue of a supply chain with a risk-neutral manufacturer and a loss-averse retailer facing stochastic demand that is sensitive to sales effort. Under the loss-averse newsvendor setting, a distribution-free gain/loss-sharing-and-buyback (GLB) contract has been shown to be able to coordinate the supply chain. However, we find that a GLB contract remains ineffective in managing the supply chain when retailer sales efforts influence the demand. To effectively coordinate the channel, we propose to combine a GLB contract with sales rebate and penalty (SRP) contract. In addition, we discover a special class of gain/loss contracts that can coordinate the supply chain and arbitrarily allocate the expected supply chain profit between the manufacturer and the retailer. We then analyze the effect of loss aversion on the retailer's decision-making behavior and supply chain performance. Finally, we perform a numerical study to illustrate the findings and gain additional insights. PMID:25197696

Anecdotally, both acute and chronic cannabis use have been associated with apathy, amotivation, and other reward processing deficits. To date, empirical support for these effects is limited, and no previous studies have assessed both acute effects of Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), as well as associations with cannabis dependence. The objectives of this study were (1) to examine acute effects of cannabis with CBD (Cann + CBD) and without CBD (Cann-CBD) on effort-related decision-making and (2) to examine associations between cannabis dependence, effort-related decision-making and reward learning. In study 1, 17 participants each received three acute vaporized treatments, namely Cann-CBD (8 mg THC), Cann + CBD (8 mg THC + 10 mg CBD) and matched placebo, followed by a 50 % dose top-up 1.5 h later, and completed the Effort Expenditure for Rewards Task (EEfRT). In study 2, 20 cannabis-dependent participants were compared with 20 non-dependent, drug-using control participants on the EEfRT and the Probabilistic Reward Task (PRT) in a non-intoxicated state. Cann-CBD reduced the likelihood of high-effort choices relative to placebo (p = 0.042) and increased sensitivity to expected value compared to both placebo (p = 0.014) and Cann + CBD (p = 0.006). The cannabis-dependent and control groups did not differ on the EEfRT. However, the cannabis-dependent group exhibited a weaker response bias than the control group on the PRT (p = 0.007). Cannabis acutely induced a transient amotivational state and CBD influenced the effects of THC on expected value. In contrast, cannabis dependence was associated with preserved motivation alongside impaired reward learning, although confounding factors, including depression, cannot be disregarded. This is the first well powered, fully controlled study to objectively demonstrate the acute amotivational effects of THC.

Using CNN Features to Better Understand What Makes Visual Artworks Special
Directory of Open Access Journals (Sweden)
Anselm Brachmann
2017-05-01
Full Text Available One of the goal of computational aesthetics is to understand what is special about visual artworks. By analyzing image statistics, contemporary methods in computer vision enable researchers to identify properties that distinguish artworks from other (non-art types of images. Such knowledge will eventually allow inferences with regard to the possible neural mechanisms that underlie aesthetic perception in the human visual system. In the present study, we define measures that capture variances of features of a well-established Convolutional Neural Network (CNN, which was trained on millions of images to recognize objects. Using an image dataset that represents traditional Western, Islamic and Chinese art, as well as various types of non-art images, we show that we need only two variance measures to distinguish between the artworks and non-art images with a high classification accuracy of 93.0%. Results for the first variance measure imply that, in the artworks, the subregions of an image tend to be filled with pictorial elements, to which many diverse CNN features respond (richness of feature responses. Results for the second measure imply that this diversity is tied to a relatively large variability of the responses of individual CNN feature across the subregions of an image. We hypothesize that this combination of richness and variability of CNN feature responses is one of properties that makes traditional visual artworks special. We discuss the possible neural underpinnings of this perceptual quality of artworks and propose to study the same quality also in other types of aesthetic stimuli, such as music and literature.

One important factor in growth, progress, and increase in work efficiency of employees of any enterprise is to make considerable effort. Supreme leader of the Islamic Republic of Iran also addressed the issue of need for more efforts. The goal of this study was to determine the association of perceived organizational justice and organizational expectations with efforts of nurses to provide a suitable model. The current study was a descriptive study. The study group consists of all nurses who worked in hospitals of Isfahan. Due to some limitations all nurses of the special unit, surgery wards and operating room were questioned. The data collection tools were the Organizational Justice Questionnaire, organizational expectations questionnaire, and double effort questionnaire. Content validity of the mentioned questionnaires was confirmed after considering the experts' comments. The reliability of these questionnaires, using the Cronbach's alpha, were 0.79, 0.83 and 0.92, respectively. The Pearson correlation and the structural equation model were used for the analysis of data. There was a significant correlation between the perceived organizational justice and the double effort of nurses during the surgery of patients. Correlation of the expectation from job, usefulness of job, and its attractiveness with double effort of nurses before the surgery was also statistically significant. Moreover, it was shown that the root of the mean square error of estimation (RMSEA) was 0.087, the fitted goodness index (GFI) was 0.953, the value of chi-square was 268.5, and the model was statistically significant (p Justice is an essential need for human life and its importance in organizations and social life of individuals is evident.

Rewards boost sustained attention through higher effort: A value-based decision making approach.
Massar, Stijn A A; Lim, Julian; Sasmita, Karen; Chee, Michael W L
2016-10-01
Maintaining sustained attention over time is an effortful process limited by finite cognitive resources. Recent theories describe the role of motivation in the allocation of such resources as a decision process: the costs of effortful performance are weighed against its gains. We examined this hypothesis by combining methods from attention research and decision neuroscience. Participants first performed a sustained attention task at different levels of reward. They then performed a reward-discounting task, measuring the subjective costs of performance. Results demonstrated that higher rewards led to improved performance (Exp 1-3), and enhanced attentional effort (i.e. pupil diameter; Exp 2 & 3). Moreover, discounting curves constructed from the choice task indicated that subjects devalued rewards that came at the cost of staying vigilant for a longer duration (Exp 1 & 2). Motivation can thus boost sustained attention through increased effort, while sustained performance is regarded as a cost against which rewards are discounted. Copyright © 2016 The Authors.

Patients with amyotrophic lateral sclerosis (ALS) are required to make decisions concerning quality of life and symptom management over the course of their disease. Clinicians perceive that patients' ability to engage in timely decision-making is extremely challenging. However, we lack patient perspectives on this issue. This study aimed to explore patient experiences of ALS, and to identify factors influencing their decision-making in the specialized multidisciplinary care of ALS. An exploratory study was conducted. Fourteen patients from two specialized ALS multidisciplinary clinics participated in semistructured interviews that were audio recorded and transcribed. Data were analyzed for emergent themes. Decision-making was influenced by three levels of factors, ie, structural, interactional, and personal. The structural factor was the decision-making environment of specialized multidisciplinary ALS clinics, which supported decision-making by providing patients with disease-specific information and specialized care planning. Interactional factors were the patient experiences of ALS, including patients' reaction to the diagnosis, response to deterioration, and engagement with the multidisciplinary ALS team. Personal factors were patients' personal philosophies, including their outlook on life, perceptions of control, and planning for the future. Patient approaches to decision-making reflected a focus on the present, rather than anticipating future progression of the disease and potential care needs. Decision-making for symptom management and quality of life in ALS care is enhanced when the patient's personal philosophy is supported by collaborative relationships between the patient and the multidisciplinary ALS team. Patients valued the support provided by the multidisciplinary team; however, their focus on living in the present diverged from the efforts of health professionals to prepare patients and their carers for the future.

Dopamine, Effort-Based Choice, and Behavioral Economics: Basic and Translational Research.
Salamone, John D; Correa, Merce; Yang, Jen-Hau; Rotolo, Renee; Presby, Rose
2018-01-01
Operant behavior is not only regulated by factors related to the quality or quantity of reinforcement, but also by the work requirements inherent in performing instrumental actions. Moreover, organisms often make effort-related decisions involving economic choices such as cost/benefit analyses. Effort-based decision making is studied using behavioral procedures that offer choices between high-effort options leading to relatively preferred reinforcers vs. low effort/low reward choices. Several neural systems, including the mesolimbic dopamine (DA) system and other brain circuits, are involved in regulating effort-related aspects of motivation. Considerable evidence indicates that mesolimbic DA transmission exerts a bi-directional control over exertion of effort on instrumental behavior tasks. Interference with DA transmission produces a low-effort bias in animals tested on effort-based choice tasks, while increasing DA transmission with drugs such as DA transport blockers tends to enhance selection of high-effort options. The results from these pharmacology studies are corroborated by the findings from recent articles using optogenetic, chemogenetic and physiological techniques. In addition to providing important information about the neural regulation of motivated behavior, effort-based choice tasks are useful for developing animal models of some of the motivational symptoms that are seen in people with various psychiatric and neurological disorders (e.g., depression, schizophrenia, Parkinson's disease). Studies of effort-based decision making may ultimately contribute to the development of novel drug treatments for motivational dysfunction.

Full Text Available Operant behavior is not only regulated by factors related to the quality or quantity of reinforcement, but also by the work requirements inherent in performing instrumental actions. Moreover, organisms often make effort-related decisions involving economic choices such as cost/benefit analyses. Effort-based decision making is studied using behavioral procedures that offer choices between high-effort options leading to relatively preferred reinforcers vs. low effort/low reward choices. Several neural systems, including the mesolimbic dopamine (DA system and other brain circuits, are involved in regulating effort-related aspects of motivation. Considerable evidence indicates that mesolimbic DA transmission exerts a bi-directional control over exertion of effort on instrumental behavior tasks. Interference with DA transmission produces a low-effort bias in animals tested on effort-based choice tasks, while increasing DA transmission with drugs such as DA transport blockers tends to enhance selection of high-effort options. The results from these pharmacology studies are corroborated by the findings from recent articles using optogenetic, chemogenetic and physiological techniques. In addition to providing important information about the neural regulation of motivated behavior, effort-based choice tasks are useful for developing animal models of some of the motivational symptoms that are seen in people with various psychiatric and neurological disorders (e.g., depression, schizophrenia, Parkinson’s disease. Studies of effort-based decision making may ultimately contribute to the development of novel drug treatments for motivational dysfunction.

A neuronal model of a global workspace in effortful cognitive tasks.
Dehaene, S; Kerszberg, M; Changeux, J P
1998-11-24
A minimal hypothesis is proposed concerning the brain processes underlying effortful tasks. It distinguishes two main computational spaces: a unique global workspace composed of distributed and heavily interconnected neurons with long-range axons, and a set of specialized and modular perceptual, motor, memory, evaluative, and attentional processors. Workspace neurons are mobilized in effortful tasks for which the specialized processors do not suffice. They selectively mobilize or suppress, through descending connections, the contribution of specific processor neurons. In the course of task performance, workspace neurons become spontaneously coactivated, forming discrete though variable spatio-temporal patterns subject to modulation by vigilance signals and to selection by reward signals. A computer simulation of the Stroop task shows workspace activation to increase during acquisition of a novel task, effortful execution, and after errors. We outline predictions for spatio-temporal activation patterns during brain imaging, particularly about the contribution of dorsolateral prefrontal cortex and anterior cingulate to the workspace.

Effort levels of the partners in networked manufacturing
Chai, G. R.; Cai, Z.; Su, Y. N.; Zong, S. L.; Zhai, G. Y.; Jia, J. H.
2017-08-01
Compared with traditional manufacturing mode, could networked manufacturing improve effort levels of the partners? What factors will affect effort level of the partners? How to encourage the partners to improve their effort levels? To answer these questions, we introduce network effect coefficient to build effort level model of the partners in networked manufacturing. The results show that (1) with the increase of the network effect in networked manufacturing, the actual effort level can go beyond the ideal level of traditional manufacturing. (2) Profit allocation based on marginal contribution rate would help improve effort levels of the partners in networked manufacturing. (3) The partners in networked manufacturing who wishes to have a larger distribution ratio must make a higher effort level, and enterprises with insufficient effort should be terminated in networked manufacturing.

Neural substrates underlying effort, time, and risk-based decision making in motivated behavior.
Bailey, Matthew R; Simpson, Eleanor H; Balsam, Peter D
2016-09-01
All mobile organisms rely on adaptive motivated behavior to overcome the challenges of living in an environment in which essential resources may be limited. A variety of influences ranging from an organism's environment, experiential history, and physiological state all influence a cost-benefit analysis which allows motivation to energize behavior and direct it toward specific goals. Here we review the substantial amount of research aimed at discovering the interconnected neural circuits which allow organisms to carry-out the cost-benefit computations which allow them to behave in adaptive ways. We specifically focus on how the brain deals with different types of costs, including effort requirements, delays to reward and payoff riskiness. An examination of this broad literature highlights the importance of the extended neural circuits which enable organisms to make decisions about these different types of costs. This involves Cortical Structures, including the Anterior Cingulate Cortex (ACC), the Orbital Frontal Cortex (OFC), the Infralimbic Cortex (IL), and prelimbic Cortex (PL), as well as the Baso-Lateral Amygdala (BLA), the Nucleus Accumbens (NAcc), the Ventral Pallidal (VP), the Sub Thalamic Nucleus (STN) among others. Some regions are involved in multiple aspects of cost-benefit computations while the involvement of other regions is restricted to information relating to specific types of costs.

Effect of social influence on effort-allocation for monetary rewards.
Gilman, Jodi M; Treadway, Michael T; Curran, Max T; Calderon, Vanessa; Evins, A Eden
2015-01-01
Though decades of research have shown that people are highly influenced by peers, few studies have directly assessed how the value of social conformity is weighed against other types of costs and benefits. Using an effort-based decision-making paradigm with a novel social influence manipulation, we measured how social influence affected individuals' decisions to allocate effort for monetary rewards during trials with either high or low probability of receiving a reward. We found that information about the effort-allocation of peers modulated participant choices, specifically during conditions of low probability of obtaining a reward. This suggests that peer influence affects effort-based choices to obtain rewards especially under conditions of risk. This study provides evidence that people value social conformity in addition to other costs and benefits when allocating effort, and suggests that neuroeconomic studies that assess trade-offs between effort and reward should consider social environment as a factor that can influence decision-making.

Motor effort alters changes of mind in sensorimotor decision making.
Directory of Open Access Journals (Sweden)
Diana Burk
Full Text Available After committing to an action, a decision-maker can change their mind to revise the action. Such changes of mind can even occur when the stream of information that led to the action is curtailed at movement onset. This is explained by the time delays in sensory processing and motor planning which lead to a component at the end of the sensory stream that can only be processed after initiation. Such post-initiation processing can explain the pattern of changes of mind by asserting an accumulation of additional evidence to a criterion level, termed change-of-mind bound. Here we test the hypothesis that physical effort associated with the movement required to change one's mind affects the level of the change-of-mind bound and the time for post-initiation deliberation. We varied the effort required to change from one choice target to another in a reaching movement by varying the geometry of the choice targets or by applying a force field between the targets. We show that there is a reduction in the frequency of change of mind when the separation of the choice targets would require a larger excursion of the hand from the initial to the opposite choice. The reduction is best explained by an increase in the evidence required for changes of mind and a reduced time period of integration after the initial decision. Thus the criteria to revise an initial choice is sensitive to energetic costs.

Dopamine does double duty in motivating cognitive effort
Westbrook, Andrew; Braver, Todd S.
2015-01-01
Cognitive control is subjectively costly, suggesting that engagement is modulated in relationship to incentive state. Dopamine appears to play key roles. In particular, dopamine may mediate cognitive effort by two broad classes of functions: 1) modulating the functional parameters of working memory circuits subserving effortful cognition, and 2) mediating value-learning and decision-making about effortful cognitive action. Here we tie together these two lines of research, proposing how dopamine serves “double duty”, translating incentive information into cognitive motivation. PMID:26889810

Making Space for Specialized Astronomy Resources
MacMillan, D.
2007-10-01
With the growth of both free and subscription-based resources, articles on astronomy have never been easier to find. Locating the best and most current materials for any given search, however, now requires multiple tools and strategies dependent on the query. An analysis of the tools currently available shows that while astronomy is well-served by Google Scholar, Scopus and Inspec, its literature is best accessed through specialized resources such as ADS (Astrophysics Data System). While no surprise to astronomers, this has major implications for those of us who teach information literacy skills to astronomy students and work in academic settings where astronomy is just one of many subjects for which our non-specialist colleagues at the reference desk provide assistance. This paper will examine some of the implications of this analysis for library instruction, reference assistance and training, and library webpage development.

Slow growth efforts renewed in Iran.
Aghajanian, A
1992-10-01
Iran's first population policy was developed under the Shah in 1967. Policymakers brought in with the Islamic Revolution of 1979, however, rejected much of the earlier regime's views on women and childbearing. During the Iran-Iraq war of 1980-88, large population size and rapid growth were seen as advantageous to the war effort. After the war, the government of Iran again began to voice concern about rapid population growth. The pragmatic and proactive approach taken by the government since 1988 may, indeed, accelerate a decline in fertility began in the late 1960s, but stalled in the 1980s. The following are examples of the new governmental attitude: the Iranian government announced March 1992 that it would begin importing Norplant and make it available along with other contraceptives at public clinics; last year, the government announced that the fourth child of a family would not be eligible for food rationing or nutritional supplements and other public child benefits; the Minister of Health in 1991 for the first time publicly encouraged male sterilization; and last fall, Iran conducted a special census of the population five years before the regular decennial census date of 1996. These actions represent dramatic policy changes on population growth and family planning in this country of 60 million, the largest and one of the fastest growing in the Middle East.

Men's Work Efforts and the Transition to Fatherhood.
Astone, Nan Marie; Dariotis, Jacinda; Sonenstein, Freya; Pleck, Joseph H; Hynes, Kathryn
2010-03-01
In this paper we tested three hypotheses: (a) the transition to fatherhood is associated with an increase in work effort; (b) the positive association (if any) between the transition to fatherhood and work effort is greater for fathers who are married at the time of the transition; and (c) the association (if any) is greater for men who make the transition at younger ages. The data are from the National Longitudinal Survey of Youth 1979 Cohort. The transition to fatherhood was associated with an increase in work effort among young unmarried men, but not for married men. Among married men who were on-time fathers, work effort decreased. Among childless men, the marriage transition was associated with increased work effort.

Access to patient-centered medical home among Ohio's Children with Special Health Care Needs.
Conrey, Elizabeth J; Seidu, Dazar; Ryan, Norma J; Chapman, Dj Sam
2013-06-01
Medical homes deliver primary care that is accessible, continuous, comprehensive, family centered, coordinated, compassionate and culturally effective. Children with special health care needs (CSHCN) require a wide range of support to maintain health, making medical home access particularly important. We sought to understand independent risk factors for lacking access. We analyzed Ohio, USA data from the National Survey of Children with Special Health Care Needs (2005-2006). Among CSHCN, 55.6% had medical home access. The proportion achieving each medical home component was highest for having a personal doctor/nurse and lowest for receiving coordinated care, family-centered care and referrals. Specific subsets of CSHCN were significantly and independently more likely to lack medical home access: Hispanic (AOR=3.08), moderate/high severity of difficulty (AOR=2.84), and any public insurance (AOR=1.60). Efforts to advance medical home access must give special attention to these CSHCN populations and improvements must be made to referral access, family-centered care, and care coordination.

The Semi-Arid Land-Surface-Atmosphere Program (SALSA) is a multi-agency, multi-national research effort that seeks to evaluate the consequences of natural and human-induced environmental change in semi-arid regions. The ultimate goal of SALSA is to advance scientific understanding of the semi-arid portion of the hydrosphere-biosphere interface in order to provide reliable information for environmental decision making. SALSA approaches this goal through a program of long-term, integrated observations, process research, modeling, assessment, and information management that is sustained by cooperation among scientists and information users. In this preface to the SALSA special issue, general program background information and the critical nature of semi-arid regions is presented. A brief description of the Upper San Pedro River Basin, the initial location for focused SALSA research follows. Several overarching research objectives under which much of the interdisciplinary research contained in the special issue was undertaken are discussed. Principal methods, primary research sites and data collection used by numerous investigators during 1997-1999 are then presented. Scientists from about 20 US, five European (four French and one Dutch), and three Mexican agencies and institutions have collaborated closely to make the research leading to this special issue a reality. The SALSA Program has served as a model of interagency cooperation by breaking new ground in the approach to large scale interdisciplinary science with relatively limited resources.

Clinicians perceive that patients’ ability to engage in timely decision-making is extremely challenging. However, we lack patient perspectives on this issue. This study aimed to explore patient experiences of ALS, and to identify factors influencing their decision-making in the specialized multidisciplinary care of ALS.Methods: An exploratory study was conducted. Fourteen patients from two specialized ALS multidisciplinary clinics participated in semistructured interviews that were audio recorded and transcribed. Data were analyzed for emergent themes.Results: Decision-making was influenced by three levels of factors, ie, structural, interactional, and personal. The structural factor was the decision-making environment of specialized multidisciplinary ALS clinics, which supported decision-making by providing patients with disease-specific information and specialized care planning. Interactional factors were the patient experiences of ALS, including patients’ reaction to the diagnosis, response to deterioration, and engagement with the multidisciplinary ALS team. Personal factors were patients’ personal philosophies, including their outlook on life, perceptions of control, and planning for the future. Patient approaches to decision-making reflected a focus on the present, rather than anticipating future progression of the disease and potential care needs.Conclusion: Decision-making for symptom management and quality of life in ALS care is enhanced when the

One of the most debilitating aspects of schizophrenia is an apparent interest in or ability to exert effort for rewards. Such "negative symptoms" may prevent individuals from obtaining potentially beneficial outcomes in educational, occupational, or social domains. In animal models, dopamine abnormalities decrease willingness to work for rewards, implicating dopamine (DA) function as a candidate substrate for negative symptoms given that schizophrenia involves dysregulation of the dopamine system. We used the effort-expenditure for rewards task (EEfRT) to assess the degree to which individuals with schizophrenia were wiling to exert increased effort for either larger magnitude rewards or for rewards that were more probable. Fifty-nine individuals with schizophrenia and 39 demographically similar controls performed the EEfRT task, which involves making choices between "easy" and "hard" tasks to earn potential rewards. Individuals with schizophrenia showed less of an increase in effort allocation as either reward magnitude or probability increased. In controls, the frequency of choosing the hard task in high reward magnitude and probability conditions was negatively correlated with depression severity and anhedonia. In schizophrenia, fewer hard task choices were associated with more severe negative symptoms and worse community and work function as assessed by a caretaker. Consistent with patterns of disrupted dopamine functioning observed in animal models of schizophrenia, these results suggest that 1 mechanism contributing to impaired function and motivational drive in schizophrenia may be a reduced allocation of greater effort for higher magnitude or higher probability rewards.

Abstract Motivation has been defined as the process that allows organisms to regulate their internal and external environment, and control the probability, proximity and availability of stimuli. As such, motivation is a complex process that is critical for survival, which involves multiple behavioural functions mediated by a number of interacting neural circuits. Classical theories of motivation suggest that there are both directional and activational aspects of motivation, and activational aspects (i.e. speed and vigour of both the instigation and persistence of behaviour) are critical for enabling organisms to overcome work-related obstacles or constraints that separate them from significant stimuli. The present review discusses the role of brain dopamine and related circuits in behavioural activation, exertion of effort in instrumental behaviour, and effort-related decision-making, based upon both animal and human studies. Impairments in behavioural activation and effort-related aspects of motivation are associated with psychiatric symptoms such as anergia, fatigue, lassitude and psychomotor retardation, which cross multiple pathologies, including depression, schizophrenia, and Parkinson’s disease. Therefore, this review also attempts to provide an interdisciplinary approach that integrates findings from basic behavioural neuroscience, behavioural economics, clinical neuropsychology, psychiatry, and neurology, to provide a coherent framework for future research and theory in this critical field. Although dopamine systems are a critical part of the brain circuitry regulating behavioural activation, exertion of effort, and effort-related decision-making, mesolimbic dopamine is only one part of a distributed circuitry that includes multiple neurotransmitters and brain areas. Overall, there is a striking similarity between the brain areas involved in behavioural activation and effort-related processes in rodents and in humans. Animal models of effort

Anhedonia, the loss of interest or pleasure in reward processing, is a hallmark feature of major depressive disorder (MDD), but its underlying neurobiological mechanism is largely unknown. The present study aimed to examine the underlying neural mechanism of reward-related decision-making in patients with MDD. We examined behavioral and neural responses to rewards in patients with first-episode MDD (N=25) and healthy controls (N=25) using the Effort-Expenditure for Rewards Task (EEfRT). The task involved choices about possible rewards of varying magnitude and probability. We tested the hypothesis that individuals with MDD would exhibit a reduced neural response in reward-related brain structures involved in cost-benefit decision-making. Compared with healthy controls, patients with MDD showed significantly weaker responses in the left caudate nucleus when contrasting the 'high reward'-'low reward' condition, and blunted responses in the left superior temporal gyrus and the right caudate nucleus when contrasting high and low probabilities. In addition, hard tasks chosen during high probability trials were negatively correlated with superior temporal gyrus activity in MDD patients, while the same choices were negatively correlated with caudate nucleus activity in healthy controls. These results indicate that reduced caudate nucleus and superior temporal gyrus activation may underpin abnormal cost-benefit decision-making in MDD. Copyright © 2015 Elsevier Inc.

Rodent models of adaptive decision making.
Izquierdo, Alicia; Belcher, Annabelle M
2012-01-01
Adaptive decision making affords the animal the ability to respond quickly to changes in a dynamic environment: one in which attentional demands, cost or effort to procure the reward, and reward contingencies change frequently. The more flexible the organism is in adapting choice behavior, the more command and success the organism has in navigating its environment. Maladaptive decision making is at the heart of much neuropsychiatric disease, including addiction. Thus, a better understanding of the mechanisms that underlie normal, adaptive decision making helps achieve a better understanding of certain diseases that incorporate maladaptive decision making as a core feature. This chapter presents three general domains of methods that the experimenter can manipulate in animal decision-making tasks: attention, effort, and reward contingency. Here, we present detailed methods of rodent tasks frequently employed within these domains: the Attentional Set-Shift Task, Effortful T-maze Task, and Visual Discrimination Reversal Learning. These tasks all recruit regions within the frontal cortex and the striatum, and performance is heavily modulated by the neurotransmitter dopamine, making these assays highly valid measures in the study of psychostimulant addiction.

[Limit of therapeutic effort in Spanish medical journals].
Solís García Del Pozo, Julián; Gómez Pérez, Ignacio
2012-01-01
In this paper we review articles concerning the limits of therapeutic effort that have been published in the past decade in journals directed at health professionals. Most of these articles are opinion pieces in which the influence of principlism is clear, even going so far as to justify the right to terminate life based on patient autonomy. It is time for personalistic bioethics to transmit its approaches in medical journals that are not specialized in bioethics.

Computer-based accountability system (Phase I) for special nuclear materials at Argonne-West
International Nuclear Information System (INIS)
Ingermanson, R.S.; Proctor, A.E.
1982-05-01
An automated accountability system for special nuclear materials (SNM) is under development at Argonne National Laboratory-West. Phase I of the development effort has established the following basic features of the system: a unique file organization allows rapid updating or retrieval of the status of various SNM, based on batch numbers, storage location, serial number, or other attributes. Access to the program is controlled by an interactive user interface that can be easily understood by operators who have had no prior background in electronic data processing. Extensive use of structured programming techniques make the software package easy to understand and to modify for specific applications. All routines are written in FORTRAN

Pediatricians Transitioning Practices, Youth With Special Health Care Needs in New York State.
Davidson, Lynn F; Chhabra, Rosy; Cohen, Hillel W; Lechuga, Claudia; Diaz, Patricia; Racine, Andrew
2015-10-01
To assess current practices of New York State pediatricians as they transition youth with special health care needs to adult-oriented medical care. A survey of New York State pediatricians included 6 critical steps from 2002 consensus statement, 11 essential steps adapted from recent literature, and questions targeting age of starting transition and availability of transition policy. Of 181 respondents, only 11% have a transition policy. Most assist patients in transition process; identify an adult provider (92%); and create portable medical summary (57%). Only 3% start planning process at recommended age. No respondents are compliant with all 6 critical steps; subspecialists were more likely to report compliance to more than 4 steps. Participating pediatricians are making gains, yet effort is needed, to incorporate the essential steps into practice for transitioning youth with special health care needs. Recognition of barriers, use of electronic tools, and clarifying subspecialist's approach, may improve compliance with transition recommendations. © The Author(s) 2015.

Men’s Work Efforts and the Transition to Fatherhood1
Astone, Nan Marie; Dariotis, Jacinda; Sonenstein, Freya; Pleck, Joseph H.; Hynes, Kathryn
2010-01-01
In this paper we tested three hypotheses: (a) the transition to fatherhood is associated with an increase in work effort; (b) the positive association (if any) between the transition to fatherhood and work effort is greater for fathers who are married at the time of the transition; and (c) the association (if any) is greater for men who make the transition at younger ages. The data are from the National Longitudinal Survey of Youth 1979 Cohort. The transition to fatherhood was associated with an increase in work effort among young unmarried men, but not for married men. Among married men who were on-time fathers, work effort decreased. Among childless men, the marriage transition was associated with increased work effort. PMID:20221306

Good Faith, Bad Faith? Making an Effort in Dispute Resolution
Directory of Open Access Journals (Sweden)
Tania Sourdin
2013-12-01
Full Text Available The behaviour of those engaged in negotiation and Alternative Dispute Resolution (ADR processes that are undertaken or required before or after litigation is increasingly the subject of legislative regulation. Recent case law has also more clearly articulated the characteristics of good faith as well as other standards such as 'genuine effort' and explored to a limited extent the behavioural indicators and approaches that could be used to determine the meaning and scope of these types of concepts. Arguably, the growth in mandatory (rather than voluntary ADR may require the articulation of clearer conduct obligations as ADR participants may be disinclined to negotiate or may be relatively unsophisticated or unaware of their negotiation behaviour. This article explores the development of conduct obligations and notes that whilst the requirements need to be linked to the circumstances of each dispute, there are some clear differences in terms of how these requirements are more generally interpreted by lawyers and others.

Novel technique of making thin target foil of high density material via rolling method
Gupta, C. K.; Rohilla, Aman; Singh, R. P.; Singh, Gurjot; Chamoli, S. K.
2018-05-01
The conventional rolling method fails to yield good quality thin foils of thicknesses less than 2 mg/cm2 for high density materials with Z ≥ 70 (e.g. gold, lead). A special and improved technique has been developed to obtain such low thickness good quality gold foils by rolling method. Using this technique thin gold foils of thickness in the range of 0.850-2.5 mg/cm2 were obtained in the present work. By making use of alcohol during rolling, foils of thickness 1 mg/cm2 can be obtained in shorter time with less effort.

Introduction to the special issue
Directory of Open Access Journals (Sweden)
Gisela Boehm
2008-01-01
Full Text Available (from the introduction Intuition and affect have been neglected topics in the literature on human judgment and decision making for a long time. Judgmental processes involved in risk perception and decision making have traditionally been conceptualized as cognitive in nature, being based upon a rational and deliberate evaluation of the alternatives at hand. This picture started to change in the early 1980s when decision researchers looked beyond rational, deliberate, and cognitive processes and began to investigate intuitive --- as opposed to deliberate --- and emotional --- as opposed to cognitive --- aspects of decision making. In sum, decision research has seen a proliferation of approaches that look beyond rational, deliberate, and purely cognitive processes in decision making and investigate intuitive and emotional judgments in this area. This seemed like a good point in time to reflect the state of this emerging field in a special issue that addresses the question of how intuition and affect are related to each other and how they shape risk perception and decision making. This special issue is the result of a workshop that was held at the University of Bergen in November, 2006.

What Makes Health Care Special?: An Argument for Health Care Insurance.
Horne, L Chad
2017-01-01
While citizens in a liberal democracy are generally expected to see to their basic needs out of their own income shares, health care is treated differently. Most rich liberal democracies provide their citizens with health care or health care insurance in kind. Is this "special" treatment justified? The predominant liberal account of justice in health care holds that the moral importance of health justifies treating health care as special in this way. I reject this approach and offer an alternative account. Health needs are not more important than other basic needs, but they are more unpredictable. I argue that citizens are owed access to insurance against health risks to provide stability in their future expectations and thus to protect their capacities for self-determination.

Practitioner's knowledge representation a pathway to improve software effort estimation
Mendes, Emilia
2014-01-01
The main goal of this book is to help organizations improve their effort estimates and effort estimation processes by providing a step-by-step methodology that takes them through the creation and validation of models that are based on their own knowledge and experience. Such models, once validated, can then be used to obtain predictions, carry out risk analyses, enhance their estimation processes for new projects and generally advance them as learning organizations.Emilia Mendes presents the Expert-Based Knowledge Engineering of Bayesian Networks (EKEBNs) methodology, which she has used and adapted during the course of several industry collaborations with different companies world-wide over more than 6 years. The book itself consists of two major parts: first, the methodology's foundations in knowledge management, effort estimation (with special emphasis on the intricacies of software and Web development) and Bayesian networks are detailed; then six industry case studies are presented which illustrate the pra...

It has been argued that, for certain people, attempts at making meaning about past life events, especially challenging events, might be detrimental to well-being. In this study we explored the association between narrative indicators of meaning-making and psychological well-being, while also considering the role of individual level factors such as life history, personality characteristics and locus of control, among an at-risk sample of low socioeconomic status inner-city African-American adolescent females with challenging lives. We found that having a more external locus of control and including more cognitive processing language in narratives about a highly negative past experience were associated with increased depressive symptoms. Our findings suggest that certain types of narrative meaning-making language may reflect ongoing and unsuccessful efforts after meaning, and, may be more similar to rumination than to resolution. Additionally, they support claims that for certain individuals from challenging backgrounds, efforts after meaning might not be psychologically healthy. PMID:22897108

Voluntary versus Enforced Team Effort
Directory of Open Access Journals (Sweden)
Claudia Keser
2011-08-01
Full Text Available We present a model where each of two players chooses between remuneration based on either private or team effort. Although at least one of the players has the equilibrium strategy to choose private remuneration, we frequently observe both players to choose team remuneration in a series of laboratory experiments. This allows for high cooperation payoffs but also provides individual free-riding incentives. Due to significant cooperation, we observe that, in team remuneration, participants make higher profits than in private remuneration. We also observe that, when participants are not given the option of private remuneration, they cooperate significantly less.

Separate valuation subsystems for delay and effort decision costs.
Prévost, Charlotte; Pessiglione, Mathias; Météreau, Elise; Cléry-Melin, Marie-Laure; Dreher, Jean-Claude
2010-10-20
Decision making consists of choosing among available options on the basis of a valuation of their potential costs and benefits. Most theoretical models of decision making in behavioral economics, psychology, and computer science propose that the desirability of outcomes expected from alternative options can be quantified by utility functions. These utility functions allow a decision maker to assign subjective values to each option under consideration by weighting the likely benefits and costs resulting from an action and to select the one with the highest subjective value. Here, we used model-based neuroimaging to test whether the human brain uses separate valuation systems for rewards (erotic stimuli) associated with different types of costs, namely, delay and effort. We show that humans devalue rewards associated with physical effort in a strikingly similar fashion to those they devalue that are associated with delays, and that a single computational model derived from economics theory can account for the behavior observed in both delay discounting and effort discounting. However, our neuroimaging data reveal that the human brain uses distinct valuation subsystems for different types of costs, reflecting in opposite fashion delayed reward and future energetic expenses. The ventral striatum and the ventromedial prefrontal cortex represent the increasing subjective value of delayed rewards, whereas a distinct network, composed of the anterior cingulate cortex and the anterior insula, represent the decreasing value of the effortful option, coding the expected expense of energy. Together, these data demonstrate that the valuation processes underlying different types of costs can be fractionated at the cerebral level.

A decision is a commitment of resources under conditions of risk in expectation of the best future outcome. The smart decision is always the strategy with the best overall expected value-the best combination of facts and values. Some of the special circumstances involved in decision making are discussed, including decisions where there are multiple goals, those where more than one person is involved in making the decision, using trigger points, framing decisions correctly, commitments to lost causes, and expert decision makers. A complex example of deciding about removal of asymptomatic third molars, with and without an EBD search, is discussed.

This report discusses the activities of organizations that seek to promote integrated resource planning and aggressive, cost-effective demand-side management by utilities. The activities of such groups -- here called energy efficiency advocacy groups (EEAGs) -- are examined in ten detailed am studies. Nine of the cases involve some form of interactive effort between investor-owned electric utilities and non-utility to develop policies, plans, or programs cooperatively. Many but not all of the interactive efforts examined are formal collaboratives. In addition, all ten cases include discussion of other EEAG activities, such as coalition-building, research, participation in statewide energy planning, and intervention in regulatory proceedings.

Full Text Available The rat anterior cingulate cortex (ACC mediates effort-based decision making when the task requires the physical effort of climbing a ramp. Normal rats will readily climb a barrier leading to high reward whereas rats with ACC lesions will opt instead for an easily obtained small reward. The present study explored whether the role of ACC in cost-benefit decisions extends beyond climbing by testing its role in ramp climbing as well as two novel cost-benefit decision tasks, one involving the physical effort of lifting weights and the other the emotional cost of overcoming fear (i.e., courage. As expected, rats with extensive ACC lesions tested on a ramp-climbing task were less likely to choose a high-reward/high-effort arm than sham controls. However, during the first few trials, lesioned rats were as likely as controls to initially turn into the high-reward arm but far less likely to actually climb the barrier, suggesting that the role of the ACC is not in deciding which course of action to pursue, but rather in maintaining a course of action in the face of countervailing forces. In the effort-reward decision task involving weight lifting, some lesion animals behaved like controls while others avoided the high reward arm. However, the results were not statistically significant and a follow-up study using incremental increasing effort failed to show any difference between lesion and control groups. The results suggest that the ACC is not needed for effort-reward decisions involving weight lifting but may affect motor abilities. Finally, a courage task explored the willingness of rats to overcome the fear of crossing an open, exposed arm to obtain a high reward. Both sham and ACC-lesioned animals exhibited equal tendencies to enter the open arm. However, whereas sham animals gradually improved on the task, ACC-lesioned rats did not. Taken together, the results suggest that the role of the ACC in effort-reward decisions may be limited to certain

Special problems in making geotechnical measurements in salt
International Nuclear Information System (INIS)
Verslvis, S.; Lindner, E.N.
1983-01-01
The transfer of experience, theory, and instrumentation suitable for hard rock media has posed numerous problems which this paper will address. Foremost of these pertains to the time-dependent (creep) behavior of salt. The theoretical mechanism is elusive; creep laws formulated to predict this behavior represent the state of the art in regression analysis. Furthermore, long term experiments (1 year) that would be necessary to determine creep mechanism(s) are enormously expensive and tie-up test equipment. Second, tests for determining in situ stress are based on the theory of elasticity. However anelastic (non-recoverable) strains contribute a significant portion of the material behavior precluding back calculating in situ stresses. Another problem pertains to the rate-dependent behavior of salt. Loading and temperature gradients experienced in the laboratory are more severe than would be experienced in a repository. Significant differences in material behavior can be expected along with special problems with instrumentation

Heart rate variability reflects self-regulatory strength, effort, and fatigue.
Segerstrom, Suzanne C; Nes, Lise Solberg
2007-03-01
Experimental research reliably demonstrates that self-regulatory deficits are a consequence of prior self-regulatory effort. However, in naturalistic settings, although people know that they are sometimes vulnerable to saying, eating, or doing the wrong thing, they cannot accurately gauge their capacity to self-regulate at any given time. Because self-regulation and autonomic regulation colocalize in the brain, an autonomic measure, heart rate variability (HRV), could provide an index of self-regulatory strength and activity. During an experimental manipulation of self-regulation (eating carrots or cookies), HRV was elevated during high self-regulatory effort (eat carrots, resist cookies) compared with low self-regulatory effort (eat cookies, resist carrots). The experimental manipulation and higher HRV at baseline independently predicted persistence at a subsequent anagram task. HRV appears to index self-regulatory strength and effort, making it possible to study these phenomena in the field as well as the lab.

Control and Effort Costs Influence the Motivational Consequences of Choice
Directory of Open Access Journals (Sweden)
Holly Sullivan-Toole
2017-05-01
Full Text Available The act of making a choice, apart from any outcomes the choice may yield, has, paradoxically, been linked to both the enhancement and the detriment of intrinsic motivation. Research has implicated two factors in potentially mediating these contradictory effects: the personal control conferred by a choice and the costs associated with a choice. Across four experiments, utilizing a physical effort task disguised as a simple video game, we systematically varied costs across two levels of physical effort requirements (Low-Requirement, High-Requirement and control over effort costs across three levels of choice (Free-Choice, Restricted-Choice, and No-Choice to disambiguate how these factors affect the motivational consequences of choosing within an effortful task. Together, our results indicated that, in the face of effort requirements, illusory control alone may not sufficiently enhance perceptions of personal control to boost intrinsic motivation; rather, the experience of actual control may be necessary to overcome effort costs and elevate performance. Additionally, we demonstrated that conditions of illusory control, while otherwise unmotivating, can through association with the experience of free-choice, be transformed to have a positive effect on motivation.

2004-12-01
To review strategies of transnational tobacco companies (TTCs) at creating a favourable advertising environment for their products in Hungary, with special regard to efforts resulting in the liberalisation of tobacco advertising in 1997. Analysis of internal tobacco industry documents relevant to Hungary available on the World Wide Web. Transcripts of speeches of members of the Parliament during the debate of the 1997 advertising act were also reviewed. The tobacco companies not only entered the Hungarian market by early participation in the privatisation of the former state tobacco monopoly, but also imported theirsophisticated marketing experiences. Evasion and violation of rules in force, creation of new partnerships, establishment and use of front groups, finding effective ways for influencing decision makers were all parts of a well orchestrated industry effort to avoid a strict marketing regulation for tobacco products.

Mesolimbic dopamine (DA) is a critical component of the brain circuitry regulating behavioral activation and effort-related processes. Research involving choice tasks has shown that rats with impaired DA transmission reallocate their instrumental behavior away from food-reinforced tasks with high response requirements and instead select less effortful food-seeking behaviors. Previous work showed that adenosine A(2A) antagonism can reverse the effects of the DA antagonist haloperidol in an operant task that assesses effort-related choice. The present work used a T-maze choice procedure to assess the effects of adenosine A(2A) and A(1) antagonism. With this task, the two arms of the maze have different reinforcement densities (four vs. two food pellets), and a vertical 44 cm barrier is positioned in the arm with the higher density, presenting the animal with an effort-related challenge. Untreated rats strongly prefer the arm with the high density of food reward and climb the barrier in order to obtain the food. Haloperidol produced a dose-related (0.05-0.15 mg/kg i.p.) reduction in the number of trials in which the rats chose the high-barrier arm. Co-administration of the adenosine A(2A) receptor antagonist MSX-3 (0.75, 1.5, and 3.0 mg/kg i.p.), but not the A(1) antagonist 8-cyclopentyl-1,3-dipropylxanthine (0.75, 1.5, and 3.0 mg/kg i.p.), reversed the effects of haloperidol on effort-related choice and latency. Adenosine A(2A) and D2 receptors interact to regulate effort-related decision making, which may have implications for the treatment of psychiatric symptoms such as psychomotor slowing or anergia that can be observed in depression, parkinsonism, and other disorders.

Discounting the value of safety: effects of perceived risk and effort.
Sigurdsson, Sigurdur O; Taylor, Matthew A; Wirth, Oliver
2013-09-01
Although falls from heights remain the most prevalent cause of fatalities in the construction industry, factors impacting safety-related choices associated with work at heights are not completely understood. Better tools are needed to identify and study the factors influencing safety-related choices and decision making. Using a computer-based task within a behavioral economics paradigm, college students were presented a choice between two hypothetical scenarios that differed in working height and effort associated with retrieving and donning a safety harness. Participants were instructed to choose the scenario in which they were more likely to wear the safety harness. Based on choice patterns, switch points were identified, indicating when the perceived risk in both scenarios was equivalent. Switch points were a systematic function of working height and effort, and the quantified relation between perceived risk and effort was described well by a hyperbolic equation. Choice patterns revealed that the perceived risk of working at heights decreased as the effort to retrieve and don a safety harness increased. Results contribute to the development of computer-based procedure for assessing risk discounting within a behavioral economics framework. Such a procedure can be used as a research tool to study factors that influence safety-related decision making with a goal of informing more effective prevention and intervention strategies.

Identification and characterization of Department of Energy special-case radioactive waste
International Nuclear Information System (INIS)
Williams, R.E.; Kudera, D.E.
1990-01-01
This paper identifies and characterizes Department of Energy (DOE) special-case radioactive wastes. Included in this paper are descriptions of the special-case waste categories and their volumes and curie contents, as well as discussions of potential methods for management of these special-case wastes. Work on extensive inventories of DOE-titled special-case waste are still in progress. All radioactive waste is characterized to determine its waste category. Some wastes may have characteristics of more than one of the major waste types. These characteristics may prevent such wastes from being managed as typical high-level, low-level, or transuranic waste. DOE has termed these wastes special-case wastes. Special-case wastes may require special management and disposal schemes. Because of these special considerations, DOE-Headquarters (HQ) required the identification of all existing and potential DOE-owned special case waste to determine future management planning and funding requirements. The inventory effort includes all commercially held, DOE-owned radioactive materials

2015-01-01
We examine how the government and the market affect firm’s pollution abatement efforts, i.e. firm’s efforts to reduce its pollution emission. The way for the government to control firm’s pollution is to impose penalty, whereas the consumers (the market) make their purchasing decision by taking into account the pollution, i.e. the demand is affected by the stock of pollution. In effect, we consider two forces, government penalty and consumer’s sensitivity to pollution, as primary factors to co...

The embodied energy in trade: What role does specialization play?
International Nuclear Information System (INIS)
Gasim, Anwar A.
2015-01-01
Many industrialized countries are net importers of embodied energy and emissions, while many developing countries are net exporters. We examine the role of specialization in driving these trade patterns by conducting a spatial index decomposition analysis on the embodied energy in net exports for 41 economies. The results reveal that industrialized countries have generally offshored energy intensive production, which many developing countries specialize in. We find that specialization, on average, makes the biggest contribution, accounting for roughly 50% of a country's embodied energy in net exports. However, other factors, namely energy intensity and the trade balance, combine to make an equally important contribution. In summary, specialization, despite its significant role, is not the only cause of the embodied energy trade patterns observed between industrialized and developing countries. - Highlights: • The embodied energy in net exports is decomposed into three contributors. • The three contributors are intensity, specialization, and the trade balance. • On average, specialization accounts for roughly 50% of embodied energy flows. • The combination of intensity and trade balance effects is equally important.

Low-ranking female Japanese macaques make efforts for social grooming.
Kurihara, Yosuke
2016-04-01
Grooming is essential to build social relationships in primates. Its importance is universal among animals from different ranks; however, rank-related differences in feeding patterns can lead to conflicts between feeding and grooming in low-ranking animals. Unifying the effects of dominance rank on feeding and grooming behaviors contributes to revealing the importance of grooming. Here, I tested whether the grooming behavior of low-ranking females were similar to that of high-ranking females despite differences in their feeding patterns. I followed 9 Japanese macaques Macaca fuscata fuscata adult females from the Arashiyama group, and analyzed the feeding patterns and grooming behaviors of low- and high-ranking females. Low-ranking females fed on natural foods away from the provisioning site, whereas high-ranking females obtained more provisioned food at the site. Due to these differences in feeding patterns, low-ranking females spent less time grooming than high-ranking females. However, both low- and high-ranking females performed grooming around the provisioning site, which was linked to the number of neighboring individuals for low-ranking females and feeding on provisioned foods at the site for high-ranking females. The similarity in grooming area led to a range and diversity of grooming partners that did not differ with rank. Thus, low-ranking females can obtain small amounts of provisioned foods and perform grooming with as many partners around the provisioning site as high-ranking females. These results highlight the efforts made by low-ranking females to perform grooming and suggest the importance of grooming behavior in group-living primates.

Full Text Available For the past few years there has been an intense and increasing collaboration effort between researchers working on the Iberian languages, and this is particularly true in the realm of phonetics and phonology. The 'Journal of Portuguese Linguistics 'has played a role in contributing to stimulate such a collaborative research focusing on the Iberian languages: first with a Special Issue on 'Variation and Change in the Iberian Languages: the Peninsula and Beyond', and now with a Special Issue on the 'Prosody of Ibero-Romance and Related Languages'. In fact, to broaden its scope of coverage to the Iberian languages has become an explicit goal of the journal. As guest-editors of this issue, we are very pleased to be able to contribute to this objective, which we find an extremely fruitful one.

Acute Stress Induces Selective Alterations in Cost/Benefit Decision-Making
Shafiei, Naghmeh; Gray, Megan; Viau, Victor; Floresco, Stan B
2012-01-01
Acute stress can exert beneficial or detrimental effects on different forms of cognition. In the present study, we assessed the effects of acute restraint stress on different forms of cost/benefit decision-making, and some of the hormonal and neurochemical mechanisms that may underlie these effects. Effort-based decision-making was assessed where rats chose between a low effort/reward (1 press=2 pellets) or high effort/reward option (4 pellets), with the effort requirement increasing over 4 blocks of trials (2, 5, 10, and 20 lever presses). Restraint stress for 1 h decreased preference for the more costly reward and induced longer choice latencies. Control experiments revealed that the effects on decision-making were not mediated by general reductions in motivation or preference for larger rewards. In contrast, acute stress did not affect delay-discounting, when rats chose between a small/immediate vs larger/delayed reward. The effects of stress on decision-making were not mimicked by treatment with physiological doses of corticosterone (1–3 mg/kg). Blockade of dopamine receptors with flupenthixol (0.25 mg/kg) before restraint did not attenuate stress-induced effects on effort-related choice, but abolished effects on choice latencies. These data suggest that acute stress interferes somewhat selectively with cost/benefit evaluations concerning effort costs. These effects do not appear to be mediated solely by enhanced glucocorticoid activity, whereas dopaminergic activation may contribute to increased deliberation times induced by stress. These findings may provide insight into impairments in decision-making and anergia associated with stress-related disorders, such as depression. PMID:22569506

This paper brings a discussion about the challenges involved in the development of a new kind of nuclear facility in Brazil, a naval base for nuclear submarines, with attention to the licensing process and considerations about the risk-informed decision making application to the licensing process. Initially, a model of such a naval base, called in this work, special industrial facility, is proposed, with its systems and respective sets of basic requirements, in order to make it possible the accomplishment of the special industrial facility support function to the nuclear submarine. A discussion about current challenges to overcome in this project is presented: the challenges due to the new characteristics of this type of nuclear facility; existence of several interfaces between the special industrial facilities systems and nuclear submarine systems in design activities; lack of specific regulation in Brazil to allow the licensing process of special industrial facilities by the nuclear safety authority; and comments about the lack of information from reference nuclear facilities, as is the case with nuclear power reactors (for example, the German Grafenrheinfeld nuclear plant is the reference plant for the Brazilian Angra 2 nuclear plant). Finally, in view of these challenges, an analysis method of special industrial facility operational scenarios to assist the licensing process is proposed. Also, considerations about the application of risk-informed decision making to the special industrial facility activity and licensing process in Brazil are presented. (author)

In the absence of a cure or vaccine for acquired immune deficiency syndrome (AIDS) educational and social marketing efforts to reduce the transmission of Human T-lymphotropic type III/lymphadenopathy-associated virus (HTLV-III/LAV) are currently our best hope for controlling the disease. Since 1983, the Centers for Disease Control (CDC) has funded a series of research studies to determine whether education efforts can successfully motivate the adoption of key behaviors relevant to the control of a variety of sexually transmitted diseases (STDs). Analysis of the first two studies which are now completed, and preliminary data from a third study, have documented dramatic changes in behavior, knowledge, and attitudes among clients in inner-city public health clinics. The authors describe the principles and underlying assumptions that have guided the design of their STD initiatives, drawing special attention to the implications for AIDS health education efforts.

2005-01-01
Many concerns have been focused on the nuclear security since the 9.11. With increasing the threat related to nuclear material and nuclear facilities, the demand of strengthening the international physical protection system has been raised. Along with this, the international communities are making their efforts to increase nuclear security. The agreement of revising the 'Convention on Physical Protection of Nuclear Materials'(hereafter, CPPNM), which was held in Vienna on the July of 2005, was one of these efforts. U.N is also preparing the 'International Convention for the Suppression of Acts of Nuclear Terrorism' to show its firm resolution against nuclear terror. It is important to understand what measures should be taken to meet the international standard for establishing national physical protection system. To do this, international trend on the physical protection system such as CPPNM and U.N. convention should be followed. This paper explains about the content of the CPPNM and U.N convention. They will be helpful to consolidate the physical protection system in Korea

Virtually all empirical ecological interaction networks to some extent suffer from undersampling. However, how limitations imposed by sampling incompleteness affect our understanding of ecological networks is still poorly explored, which may hinder further advances in the field. Here, we use a plant-hummingbird network with unprecedented sampling effort (2716 h of focal observations) from the Atlantic Rainforest in Brazil, to investigate how sampling effort affects the description of network structure (i.e. widely used network metrics) and the relative importance of distinct processes (i.e. species abundances vs. traits) in determining the frequency of pairwise interactions. By dividing the network into time slices representing a gradient of sampling effort, we show that quantitative metrics, such as interaction evenness, specialization (H2 '), weighted nestedness (wNODF) and modularity (Q; QuanBiMo algorithm) were less biased by sampling incompleteness than binary metrics. Furthermore, the significance of some network metrics changed along the sampling effort gradient. Nevertheless, the higher importance of traits in structuring the network was apparent even with small sampling effort. Our results (i) warn against using very poorly sampled networks as this may bias our understanding of networks, both their patterns and structuring processes, (ii) encourage the use of quantitative metrics little influenced by sampling when performing spatio-temporal comparisons and (iii) indicate that in networks strongly constrained by species traits, such as plant-hummingbird networks, even small sampling is sufficient to detect their relative importance for the frequencies of interactions. Finally, we argue that similar effects of sampling are expected for other highly specialized subnetworks. © 2015 The Authors. Journal of Animal Ecology © 2015 British Ecological Society.

Markets Drive the Specialization Strategies of Forest Peoples
Directory of Open Access Journals (Sweden)
Manuel Ruiz-Pérez
2004-12-01
Full Text Available Engagement in the market changes the opportunities and strategies of forest-related peoples. Efforts to support rural development need to better understand the potential importance of markets and the way people respond to them. To this end, we compared 61 case studies of the commercial production and trade of nontimber forest products from Asia, Africa, and Latin America. The results show that product use is shaped by local markets and institutions, resource abundance, and the relative level of development. Larger regional patterns are also important. High-value products tend to be managed intensively by specialized producers and yield substantially higher incomes than those generated by the less specialized producers of less managed, low-value products. We conclude that commercial trade drives a process of intensified production and household specialization among forest peoples.

Manager’s Dilemma: Stockholders’ and Consumers’ Responses to Corporate Environmental Efforts
Directory of Open Access Journals (Sweden)
Prayag Lal Yadav
2017-06-01
Full Text Available This study aims to reveal that different stakeholders have different environmental preferences by demonstrating the managers’ dilemma of selecting an appropriate environmental strategy to achieve firms’ corporate goals. It analyzes the effects of firms’ efforts in environmental impact through actual environmental practices and environmental considerations in environmental management on stockholders’ and consumers’ responses by using the Newsweek Green Rankings 2012 for large US-based firms. The study uses the event study methodology and the ordinary least squares multivariate regression model conditioned with relevant firm and industry-specific characteristics. The results indicate that both stockholders and consumers appreciate corporate efforts in reducing environmental damage; however, consumers exhibit a significant and negative response against firms’ environmental management efforts. The conflicting results provide valuable insights into the alignment of environmental efforts for developing core competencies that lead firms toward sustainability. Further, this research makes a valuable contribution to the existing literature and provides guidelines for the formulation of public policies that encourage corporate environmental efforts to ensure simultaneous development of business and society.

The joint KfK and IPP project for the development of thermonuclear fusion device is established as the centerpiece of Federal German efforts in this field. It is meant to enhance the German contribution to the European programme and thus foster the chances of a joint European large-scale experiment to be started in the Federal Republic of Germany. IPP's tasks in the project are to study the physical principles and aspects, whereas KfK is responsible for the technological aspects. Work at IPP is focused on divertor experiments with the ASDEX series in order to go deeper into the problems that could not be solved by the JET experiments, namely those of the plasma boundary and control of impurities. Stellarator experiments are made in order to study the potentials of this toroidal confinement concept for steady-state operation. The IPP which always has been working in the plasma physics field devotes all activities to the joint effort. KfK has established a special project group for this purpose, PKF. The budgeting programme presented therefore covers the IPP entire working schedule, and that of PKF of the KfK. (orig./GG) [de

Indifference to the new realities of the post-cold war era does nothing to preserve the traditional priorities laid down in the Final Document of the first special session on disarmament. On the contrary, such attitudes directly contribute to the trend towards marginalization which began when publics no longer feared the threat of a nuclear holocaust. It is believed that the expertise of forty years of multilateral arms control and disarmament efforts is directly relevant to the broader efforts of the international community to restore, maintain and promote international peace and security. Who can deny that confidence-building is central to preventive diplomacy? Or that the arms control component-from disarming to demobilization-is not equally central to peace operations whether they be traditional peace-keeping or post-conflict peace-building? Indeed the success or failure of the disarmament aspect of a peace operation is often critical to its overall success-Somalia surely being one recent sad example. The multilateral disarmament community must apply itself more directly and systematically to these broader problems - just as the United Nations Secretariat has increasingly begun to do - or risk indifference from Governments forced to make tough choices against a range of competing priorities. It is undeniably true that the post-cold war has significantly increased the potential for the international community to negotiate historic new multilateral disarmament treaties. And this window of opportunity must be utilized to the fullest. At the same time, due account must be taken of the hard fact that, for an increasing number of countries, expensive obligations in relation to advanced unconventional weapons which neither they nor their neighbours seek to possess may count for less than practical assistance in finding solutions to more parochial, but no less urgent, problems

Although physical effort can impose significant costs on decision-making, when and how effort cost information is incorporated into choice remains contested, reflecting a larger debate over the role of sensorimotor networks in specifying behavior. Serial information processing models, in which motor circuits simply implement the output of cognitive systems, hypothesize that effort cost factors into decisions relatively late, via integration with stimulus values into net (combined) value signals in dorsomedial frontal cortex (dmFC). In contrast, ethology-inspired approaches suggest a more active role for the dorsal sensorimotor stream, with effort cost signals emerging rapidly after stimulus onset. Here we investigated the time course of effort cost integration using event-related potentials in hungry human subjects while they made decisions about expending physical effort for appetitive foods. Consistent with the ethological perspective, we found that effort cost was represented from as early as 100-250 ms after stimulus onset, localized to dorsal sensorimotor regions including middle cingulate, somatosensory, and motor/premotor cortices. However, examining the same data time-locked to motor output revealed net value signals combining stimulus value and effort cost approximately -400 ms before response, originating from sensorimotor areas including dmFC, precuneus, and posterior parietal cortex. Granger causal connectivity analysis of the motor effector signal in the time leading to response showed interactions between these sensorimotor regions and ventrolateral prefrontal cortex, a structure associated with adjusting behavior-response mappings. These results suggest that rapid activation of sensorimotor regions interacts with cognitive valuation systems, producing a net value signal reflecting both physical effort and reward contingencies. Although physical effort imposes a cost on choice, when and how effort cost influences neural correlates of decision-making

Parental advocacy styles for special education students during the transition to adulthood.
Rehm, Roberta S; Fisher, Lucille T; Fuentes-Afflick, Elena; Chesla, Catherine A
2013-10-01
In an ethnographic study of planning for the transition to adulthood, we explored parental advocacy styles in special education settings for youth and young adults with chronic health conditions and developmental disabilities. Of 61 parents, 43 were satisfied with outcomes in negotiations for school services for their children. We identified three parental advocacy styles for these parents: (a) high-profile parents, who insisted on specific, wide-ranging services for their children that often resulted in conflict with educators; (b) strategic parents, who negotiated for selected goals and were willing to compromise, and (c) grateful-gratifier parents, who formed close relationships with educators and trusted them to make appropriate decisions. Eighteen parents were overwhelmed, burned out, or unfocused, and generally dissatisfied with outcomes of educational planning meetings. Professional efforts to enhance parental advocacy can target development of skills and strategies that have worked for successful negotiators.

Special graphite is considered as a critical component of the present-day tokamaks wherein it acts as the armour material for plasma-facing components. This graphite is required to possess, besides other characteristics, high values of bulk density, bending strength and electrical and thermal conductivities and a low value of ash content. Since such graphite was not commercially available in the country, efforts to develop it were initiated at the National Physical Laboratory, New Delhi. The basic approach to develop this graphite was based on green coke method of making the high density graphite, wherein the green coke was modified by incorporating in it small amounts of conducting carbon materials, i.e. needle coke, synthetic graphite and natural graphite. The resulting graphites were characterized with respect to various physical characteristics, namely, green density, weight loss, volume shrinkage, linear shrinkage, bulk density, bending strength, Young's modulus and electrical resistivity, etc. The results are described and discussed in the present paper. 6 refs., 2 tabs.

On the Cost-vs-Quality Tradeoff in Make-or-Buy Decisions
Andersson, Fredrik
2010-01-01
The make-or-buy decision is analyzed in a simple two-task principal-agent model. There is a cost-saving/quality tradeoff in effort provision. The principal faces a dichotomous choice between weak ("make") and strong ("buy") cost-saving incentives for the agent; the dichotomy is due to an incomplete-contracting limitation necessitating that one party be residual claimant. Choosing "buy" rather than "make" leads to higher cost-saving effort and -- in a plausible "main case" -- to lower quality ...

Full Text Available Wills are important social, economic, and legal documents. Yet little is known about current will making practices and intentions. A comprehensive national database on the prevalence of will making in Australia was developed to identify who is or is not most likely to draw up a will and triggers for making and changing wills. A national survey of 2,405 adults aged above 18 years was administered by telephone in August and September 2012. Fifty-nine percent of the Australian adult population has a valid will, and the likelihood of will making increases with age and estate value. Efforts to get organized, especially in combination with life stage and asset changes trigger will making; procrastination, rather than a strong resistance, appears to explain not making a will. Understanding will making is timely in the context of predicted significant intergenerational transfers of wealth, changing demographics, and a renewed emphasis on retirement planning.

However, emerging evidence to the contrary indicates that efforts to specialize in 1 sport may reduce opportunities for all children to participate in a diverse year-round sports season and can lead to lost development of lifetime sports skills. Early sports specialization may also reduce motor skill development and ongoing participation in games and sports as a lifestyle choice. The purpose of this review is to employ the current literature to provide evidence-based alternative strategies that may help to optimize opportunities for all aspiring young athletes to maximize their health, fitness, and sports performance. Evidence Acquisition: Nonsystematic review with critical appraisal of existing literature. Study Design: Clinical review. Level of Evidence: Level 4. Conclusion: Based on the current evidence, parents and educators should help provide opportunities for free unstructured play to improve motor skill development and youth should be encouraged to participate in a variety of sports during their growing years to influence the development of diverse motor skills. For those children who do choose to specialize in a single sport, periods of intense training and specialized sport activities should be closely monitored for indicators of burnout, overuse injury, or potential decrements in performance due to overtraining. Last, the evidence indicates that all youth should be involved in periodized strength and conditioning (eg, integrative neuromuscular training) to help them prepare for the demands of competitive sport participation, and youth who specialize in a single sport should plan periods of isolated and focused integrative neuromuscular training to enhance diverse motor skill development and reduce injury risk factors.

Rattling nucleons: New developments in active interrogation of special nuclear material
International Nuclear Information System (INIS)
Runkle, Robert C.; Chichester, David L.; Thompson, Scott J.
2012-01-01
Active interrogation is a vigorous area of research and development due to its promise of offering detection and characterization capabilities of special nuclear material in environments where passive detection fails. The primary value added by active methods is the capability to penetrate shielding - special nuclear material itself, incidental materials, or intentional shielding - and advocates hope that active interrogation will provide a solution to the problem of detecting shielded uranium, which is at present the greatest obstacle to interdiction efforts. The technique also provides a unique benefit for quantifying nuclear material in high background-radiation environments, an area important for nuclear material safeguards and material accountancy. Progress has been made in the field of active interrogation on several fronts, most notably in the arenas of source development, systems integration, and the integration and exploitation of multiple fission and non-fission signatures. But penetration of interrogating radiation often comes at a cost, not only in terms of finance and dose but also in terms of induced backgrounds, system complexity, and extended measurement times (including set up and acquisition). These costs make the calculus for deciding to implement active interrogation more subtle than may be apparent. The purpose of this review is thus to examine existing interrogation methods, compare and contrast their attributes and limitations, and identify missions where active interrogation may hold the most promise.

A logic road from special relativity to general relativity
Andréka, Hajnal; Madarász, Judit X.; Németi, István; Székely, Gergely
2010-01-01
We present a streamlined axiom system of special relativity in first-order logic. From this axiom system we "derive" an axiom system of general relativity in two natural steps. We will also see how the axioms of special relativity transform into those of general relativity. This way we hope to make general relativity more accessible for the non-specialist.

Towards an Early Software Effort Estimation Based on Functional and Non-Functional Requirements
Kassab, Mohamed; Daneva, Maya; Ormandjieva, Olga
The increased awareness of the non-functional requirements as a key to software project and product success makes explicit the need to include them in any software project effort estimation activity. However, the existing approaches to defining size-based effort relationships still pay insufficient attention to this need. This paper presents a flexible, yet systematic approach to the early requirements-based effort estimation, based on Non-Functional Requirements ontology. It complementarily uses one standard functional size measurement model and a linear regression technique. We report on a case study which illustrates the application of our solution approach in context and also helps evaluate our experiences in using it.

Determination of effective effort on hake Merluccius merluccius in a Mediterranean trawl fishery
Directory of Open Access Journals (Sweden)
Francisco Alemany
2003-12-01
Full Text Available The direct control of fishing effort as a management tool is of special interest in the Mediterranean, where the lack of effective international management systems and the high diversity of the catches significantly increases the complexity of implementing TAC´s as an indirect control of fishing effort. However, its enforcement should be based on the precise knowledge of the relationship between the fishing effort and its corresponding fishing mortality. In this sense, the general aim of this study was to develop an approach for analysing this relationship. In order to estimate the annual effective fishing effort on hake, a relational data base including daily landings by vessel and species of trawl fleet based on the port of Palma, Mallorca island (western Mediterranean during the period 1983-1991 was built. Fishing mortalities were available from VPA. Fishing effort and fishing mortality were split by subfleets or métiers which were identified by cluster analysis. Significant linear relationships between the two parameters were obtained when fishing effort was considered as the number of days in which hake catch was higher than 10 kg multiplied by GRT of correspondent vessels. These CPUE values are mainly obtained when trawlers operate in the muddy bottoms of the shelf and on the upper slope, where hake populations are mostly distributed. On the other hand, no clear trends in catchability by métier were found during the period analysed.

Zero Effort Technologies Considerations, Challenges, and Use in Health, Wellness, and Rehabilitation
Mihailidis, Alex; Hoey, Jesse
2011-01-01
This book introduces zero-effort technologies (ZETs), an emerging class of technology that requires little or no effort from the people who use it. ZETs use advanced techniques, such as computer vision, sensor fusion, decision-making and planning, and machine learning to autonomously operate through the collection, analysis, and application of data about the user and his/her context. This book gives an overview of ZETs, presents concepts in the development of pervasive intelligent technologies and environments for health and rehabilitation, along with an in-depth discussion of the design princ

EFFORTS AND INEQUALITY OF OPPORTUNITIES IN THE BOLIVIAN LABOR MARKET
Directory of Open Access Journals (Sweden)
Fátima Rico Encinas
2016-01-01
Full Text Available The equitable distribution of income, along with human development indices, is among the factors that differentiate developed from developing countries. In this paper, efforts and other variables related to the circumstances of individuals were quantified and analyzed together with traditional determinants in order to explain inequality in the working population of Bolivia. We estimated econometric models by merging the extended Mincer equation with John Roemer’s theory of Inequality of Opportunity. We find that efforts are important determinants of the levels of wage inequality in the country as well as regional development, labor informality, gender and ethnicity. In this sense, the paper separates the part of wage inequality that may be attributed to situations that are beyond the control of individuals and that can be attributed to conscious decisions. Micro simulations determined that it would be possible to reduce inequality by as much as 21% if it gives people the chance to make similar efforts to improve their wages.

Mental fatigue impairs soccer-specific decision-making skill.
Smith, Mitchell R; Zeuwts, Linus; Lenoir, Matthieu; Hens, Nathalie; De Jong, Laura M S; Coutts, Aaron J
2016-07-01
This study aimed to investigate the impact of mental fatigue on soccer-specific decision-making. Twelve well-trained male soccer players performed a soccer-specific decision-making task on two occasions, separated by at least 72 h. The decision-making task was preceded in a randomised order by 30 min of the Stroop task (mental fatigue) or 30 min of reading from magazines (control). Subjective ratings of mental fatigue were measured before and after treatment, and mental effort (referring to treatment) and motivation (referring to the decision-making task) were measured after treatment. Performance on the soccer-specific decision-making task was assessed using response accuracy and time. Visual search behaviour was also assessed throughout the decision-making task. Subjective ratings of mental fatigue and effort were almost certainly higher following the Stroop task compared to the magazines. Motivation for the upcoming decision-making task was possibly higher following the Stroop task. Decision-making accuracy was very likely lower and response time likely higher in the mental fatigue condition. Mental fatigue had unclear effects on most visual search behaviour variables. The results suggest that mental fatigue impairs accuracy and speed of soccer-specific decision-making. These impairments are not likely related to changes in visual search behaviour.

Neuroeconomics: cross-currents in research on decision-making.
Sanfey, Alan G; Loewenstein, George; McClure, Samuel M; Cohen, Jonathan D
2006-03-01
Despite substantial advances, the question of how we make decisions and judgments continues to pose important challenges for scientific research. Historically, different disciplines have approached this problem using different techniques and assumptions, with few unifying efforts made. However, the field of neuroeconomics has recently emerged as an inter-disciplinary effort to bridge this gap. Research in neuroscience and psychology has begun to investigate neural bases of decision predictability and value, central parameters in the economic theory of expected utility. Economics, in turn, is being increasingly influenced by a multiple-systems approach to decision-making, a perspective strongly rooted in psychology and neuroscience. The integration of these disparate theoretical approaches and methodologies offers exciting potential for the construction of more accurate models of decision-making.

Brain correlates of the intrinsic subjective cost of effort in sedentary volunteers.
Bernacer, J; Martinez-Valbuena, I; Martinez, M; Pujol, N; Luis, E; Ramirez-Castillo, D; Pastor, M A
2016-01-01
One key aspect of motivation is the ability of agents to overcome excessive weighting of intrinsic subjective costs. This contribution aims to analyze the subjective cost of effort and assess its neural correlates in sedentary volunteers. We recruited a sample of 57 subjects who underwent a decision-making task using a prospective, moderate, and sustained physical effort as devaluating factor. Effort discounting followed a hyperbolic function, and individual discounting constants correlated with an indicator of sedentary lifestyle (global physical activity questionnaire; R=-0.302, P=0.033). A subsample of 24 sedentary volunteers received a functional magnetic resonance imaging scan while performing a similar effort-discounting task. BOLD signal of a cluster located in the dorsomedial prefrontal cortex correlated with the subjective value of the pair of options under consideration (Z>2.3, Preward correlated with the signal of a cluster in the ventrolateral prefrontal cortex (Z>2.3, Pintrinsic subjective cost of effort and its neural correlates in sedentary individuals. © 2016 Elsevier B.V.

New Mexico district work-effort analysis computer program
Hiss, W.L.; Trantolo, A.P.; Sparks, J.L.
1972-01-01
The computer program (CAN 2) described in this report is one of several related programs used in the New Mexico District cost-analysis system. The work-effort information used in these programs is accumulated and entered to the nearest hour on forms completed by each employee. Tabulating cards are punched directly from these forms after visual examinations for errors are made. Reports containing detailed work-effort data itemized by employee within each project and account and by account and project for each employee are prepared for both current-month and year-to-date periods by the CAN 2 computer program. An option allowing preparation of reports for a specified 3-month period is provided. The total number of hours worked on each account and project and a grand total of hours worked in the New Mexico District is computed and presented in a summary report for each period. Work effort not chargeable directly to individual projects or accounts is considered as overhead and can be apportioned to the individual accounts and projects on the basis of the ratio of the total hours of work effort for the individual accounts or projects to the total New Mexico District work effort at the option of the user. The hours of work performed by a particular section, such as General Investigations or Surface Water, are prorated and charged to the projects or accounts within the particular section. A number of surveillance or buffer accounts are employed to account for the hours worked on special events or on those parts of large projects or accounts that require a more detailed analysis. Any part of the New Mexico District operation can be separated and analyzed in detail by establishing an appropriate buffer account. With the exception of statements associated with word size, the computer program is written in FORTRAN IV in a relatively low and standard language level to facilitate its use on different digital computers. The program has been run only on a Control Data Corporation

Full Text Available The psychobiological model of endurance performance proposes that endurance performance is determined by a decision-making process based on perception of effort and potential motivation. Recent research has reported that effort-based decision-making during cognitive tasks can be altered by non-conscious visual cues relating to affect and action. The effect of these non-conscious visual cues on effort and performance during physical tasks is however unknown. We report two experiments investigating the effect of subliminal priming with visual cues related to affect and action on perception of effort and endurance performance. In Experiment 1 thirteen individuals were subliminally primed with happy or sad faces as they cycled to exhaustion in a counterbalanced and randomized crossover design. A paired t-test (happy vs. sad faces revealed that individuals cycled for significantly longer (178 s, p = .04 when subliminally primed with happy faces. A 2 x 5 (condition x iso-time ANOVA also revealed a significant main effect of condition on rating of perceived exertion (RPE during the time to exhaustion (TTE test with lower RPE when subjects were subliminally primed with happy faces (p = .04. In Experiment 2, a single-subject randomization tests design found that subliminal priming with action words facilitated a significantly longer (399 s, p = .04 TTE in comparison to inaction words (p = .04. Like Experiment 1, this greater TTE was accompanied by a significantly lower RPE (p = .03. These experiments are the first to show that subliminal visual cues relating to affect and action can alter perception of effort and endurance performance. Non-conscious visual cues may therefore influence the effort-based decision-making process that is proposed to determine endurance performance. Accordingly, the findings raise notable implications for individuals who may encounter such visual cues during endurance competitions, training, or health related exercise.

The last decades have seen scholars argue for a greater integration of science and decision-making in order to more effectively respond to climate change. It has been suggested that overcoming the gap between science, on the one hand, and policy-making and management, on the other, requires building bridges through methods of co-production, creating actionable science, or through boundary organizations. In this paper, we review attempts at co-production for policy-making and management in the context of climate change adaptation in California. Building on field research, including numerous interviews conducted with scientists and decision-makers who are co-producers of adaptation projects, we make three arguments. First, we show that an emphasis on co-production and science-informed climate change adaptation decision-making has bolstered a contract-oriented, and decentralized network-based model of producing climate science. Second, reviewing successes and failures in co-production - as reported in interviews - indicates that it is principally in cases of neatly defined, and spatially and temporarily narrow decision-making contexts, and with highly motivated decision-makers, that climate science is used. Finally, we suggest that the ideas of co-production and actionable science may have increased the institutional and organizational burden at the science-decision interface, lengthening the boundary-organization-chain rather than necessarily facilitating adaptive policy-making and management.

The cardiovascular responses to combined static-dynamic effort, postprandial dynamic effort and dynamic effort alone were evaluated by upright bicycle ergometry during equilibrium-gated blood pool scintigraphy in 24 men, mean age 59 +/- 8 years, with chronic ischemic heart disease. Combined static-dynamic effort and the postprandial state elicited a peak cardiovascular response similar to that of dynamic effort alone. Heart rate, intraarterial systolic and diastolic pressures, rate-pressure product and ejection fraction were similar for the three test conditions at the onset of ischemia and at peak effort. The prevalence and extent of exercise-induced ischemic left ventricular dysfunction, ST-segment depression, angina pectoris and ventricular ectopic activity were also similar during the three test conditions. Direct and indirect measurements of systolic and diastolic blood pressure were highly correlated. The onset of ischemic ST-segment depression and angina pectoris correlated as strongly with heart rate alone as with the rate-pressure product during all three test conditions. The cardiovascular response to combined static-dynamic effort and to postprandial dynamic effort becomes more similar to that of dynamic effort alone as dynamic effort reaches a symptom limit. If significant ischemic and arrhythmic abnormalities are absent during symptom-limited dynamic exercise testing, they are unlikely to appear during combined static-dynamic or postprandial dynamic effort

Effort in Multitasking: Local and Global Assessment of Effort.
Kiesel, Andrea; Dignath, David
2017-01-01
When performing multiple tasks in succession, self-organization of task order might be superior compared to external-controlled task schedules, because self-organization allows optimizing processing modes and thus reduces switch costs, and it increases commitment to task goals. However, self-organization is an additional executive control process that is not required if task order is externally specified and as such it is considered as time-consuming and effortful. To compare self-organized and externally controlled task scheduling, we suggest assessing global subjective and objectives measures of effort in addition to local performance measures. In our new experimental approach, we combined characteristics of dual tasking settings and task switching settings and compared local and global measures of effort in a condition with free choice of task sequence and a condition with cued task sequence. In a multi-tasking environment, participants chose the task order while the task requirement of the not-yet-performed task remained the same. This task preview allowed participants to work on the previously non-chosen items in parallel and resulted in faster responses and fewer errors in task switch trials than in task repetition trials. The free-choice group profited more from this task preview than the cued group when considering local performance measures. Nevertheless, the free-choice group invested more effort than the cued group when considering global measures. Thus, self-organization in task scheduling seems to be effortful even in conditions in which it is beneficiary for task processing. In a second experiment, we reduced the possibility of task preview for the not-yet-performed tasks in order to hinder efficient self-organization. Here neither local nor global measures revealed substantial differences between the free-choice and a cued task sequence condition. Based on the results of both experiments, we suggest that global assessment of effort in addition to

This case describes a change effort to move a police agency to become a community policing organization. The community policing effort was seen as a means to make a transformational change to become a learning organization with the goal of improving the delivery of police services. The case describes the steps taken to meet the new vision of community policing as well as the steps taken to deal with the challenges or realities of trying to make change happen. The lens for this case is the leadership role across the stages of change (exploration, planning, implementation, monitoring and institutionalization) in building capacity within the organization to sustain the change effort. The capacity building focused on incorporating systems thinking into the mindset of the members of the organization, breaking down the command and control mindset by building a new norm around high involvement of committed teams, and developing skill sets to support continuous learning and improvement in order to align organizational systems. A key lesson learned is that effective leaders do not just prepare an organization prior to a change effort. They must have the patience to constantly build the capacity for change among organizational members throughout the various stages of the change effort.

The influence of music on mental effort and driving performance.
Ünal, Ayça Berfu; Steg, Linda; Epstude, Kai
2012-09-01
The current research examined the influence of loud music on driving performance, and whether mental effort mediated this effect. Participants (N=69) drove in a driving simulator either with or without listening to music. In order to test whether music would have similar effects on driving performance in different situations, we manipulated the simulated traffic environment such that the driving context consisted of both complex and monotonous driving situations. In addition, we systematically kept track of drivers' mental load by making the participants verbally report their mental effort at certain moments while driving. We found that listening to music increased mental effort while driving, irrespective of the driving situation being complex or monotonous, providing support to the general assumption that music can be a distracting auditory stimulus while driving. However, drivers who listened to music performed as well as the drivers who did not listen to music, indicating that music did not impair their driving performance. Importantly, the increases in mental effort while listening to music pointed out that drivers try to regulate their mental effort as a cognitive compensatory strategy to deal with task demands. Interestingly, we observed significant improvements in driving performance in two of the driving situations. It seems like mental effort might mediate the effect of music on driving performance in situations requiring sustained attention. Other process variables, such as arousal and boredom, should also be incorporated to study designs in order to reveal more on the nature of how music affects driving. Copyright © 2012 Elsevier Ltd.

The Use of the Evidence from the Behavioral Sciences in the Organizational Decision-Making Process
Directory of Open Access Journals (Sweden)
Bogdan MÎNJINĂ
2015-09-01
Full Text Available The important managerial decision-making and the development of policies, strategies, internal normative acts and procedures must be solid grounded for efficient achieving of their objectives. To this end, the evidence-based approach uses various types of evidence, a leading role having those scientific, and the critical thinking. The evidence from behavioral sciences is especially important when the decisions objectives involve behavioral elements. They also help to ensure the rationality of any decision-making process. The concern for the use of behavioral sciences research in the decision-making preceded the occurrence of evidence-based approach. The increased knowledge fund of organizations, the access to the best practices and to the relevant scientific research findings represent only the initial stages of the evidence-based approach implementation and functioning. The ensuring of their effective use calls for special skills training among staff, the creation of tools and organizational mechanisms and of a facilitating organizational culture. This paper argues the need to integrate two approaches that promote the decision-making based on scientific evidence, the evidence-based approach and the use of behavioral and social sciences in the decision-making, to potentiate the contribution of the behavioral sciences to the increasing of the decision-making efficiency. The efforts made in this paper had overall objective to prepare and facilitate the use of research evidence provided by behavioral sciences in the organizational decision-making process by presenting the main concepts and knowledge in the field and by proposing an outline procedure specifically developed.

Estimation of inspection effort
International Nuclear Information System (INIS)
Mullen, M.F.; Wincek, M.A.
1979-06-01
An overview of IAEA inspection activities is presented, and the problem of evaluating the effectiveness of an inspection is discussed. Two models are described - an effort model and an effectiveness model. The effort model breaks the IAEA's inspection effort into components; the amount of effort required for each component is estimated; and the total effort is determined by summing the effort for each component. The effectiveness model quantifies the effectiveness of inspections in terms of probabilities of detection and quantities of material to be detected, if diverted over a specific period. The method is applied to a 200 metric ton per year low-enriched uranium fuel fabrication facility. A description of the model plant is presented, a safeguards approach is outlined, and sampling plans are calculated. The required inspection effort is estimated and the results are compared to IAEA estimates. Some other applications of the method are discussed briefly. Examples are presented which demonstrate how the method might be useful in formulating guidelines for inspection planning and in establishing technical criteria for safeguards implementation

Full Text Available Objective – The objective of this study was to examine and call attention to the current deficiency in standardized performance measures and usage metrics suited to assessing the value and impact of special collections and archives and their contributions to the mission of academic research libraries and to suggest possible approaches to overcoming the deficiency.Methods – The authors reviewed attempts over the past dozen years by the Association of Research Libraries (ARL and the Association of College and Research Libraries (ACRL to highlight the unique types of value that special collections and archival resources contribute to academic research libraries. They also examined the results of a large survey of special collections and archives conducted by OCLC Research in 2010. In addition, they investigated efforts by the Society of American Archivists (SAA dating back to the 1940s to define standardized metrics for gathering and comparing data about archival operations. Finding that the library and archival communities have thus far failed to develop and adopt common metrics and methods for gathering data about the activities of special collections and archives, the authors explored the potential benefits of borrowing concepts for developing user-centered value propositions and metrics from the business community.Results – This study found that there has been a lack of consensus and precision concerning the definition of “special collections” and the value propositions they offer, and that most attempts have been limited in their usefulness because they were collections-centric. The study likewise reaffirmed a lack of consensus regarding how to define and measure basic operations performed by special collections and archives, such as circulating materials to users in supervised reading rooms. The review of concepts and metrics for assessing value in the business community, however, suggested new approaches to defining metrics that

Special event planning for the emergency manager.
Gaynor, Peter T
2009-11-01
In the domain of emergency management and homeland security there is a lack of a formal planning process at the local level when it comes to special event planning. The unique nature of special event planning demands an understanding of the planning process for both traditional and non-traditional planning partners. This understanding will make certain that local governments apply due diligence when planning for the safety of the public. This paper offers a practical roadmap for planning at the local level. It will address those 'special events' that are beyond routine local events but not of a sufficient scale to be granted National Special Security Event status. Due to the infrequency of 'special events' in most communities, it is imperative that deliberate planning takes place. Upon conclusion, the reader will be able to construct a planning process tailored to the needs of their community, guide both traditional and non-traditional planning partners through the planning process, determine priorities, explore alternatives, plan for contingencies, conduct a confirmation brief, facilitate operations and assemble an after-action report and improvement plan.

We report three cases of effortful echolalia in patients with cerebral infarction. The clinical picture of speech disturbance is associated with Type 1 Transcortical Motor Aphasia (TCMA, Goldstein, 1915). The patients always spoke nonfluently with loss of speech initiative, dysarthria, dysprosody, agrammatism, and increased effort and were unable to repeat sentences longer than those containing four or six words. In conversation, they first repeated a few words spoken to them, and then produced self initiated speech. The initial repetition as well as the subsequent self initiated speech, which were realized equally laboriously, can be regarded as mitigated echolalia (Pick, 1924). They were always aware of their own echolalia and tried to control it without effect. These cases demonstrate that neither the ability to repeat nor fluent speech are always necessary for echolalia. The possibility that a lesion in the left medial frontal lobe, including the supplementary motor area, plays an important role in effortful echolalia is discussed.

Decision-making on shared sanitation in the informal settlements of Kisumu, Kenya.
Simiyu, Sheillah; Swilling, Mark; Cairncross, Sandy
2017-10-01
Unlike most quantitative studies that investigate decision-making on investing in sanitation, this study adopted a qualitative approach to investigate decision-making on shared sanitation in the informal settlements of Kisumu city, in Kenya. Using a grounded theory approach, landlords and tenants were interviewed to identify sanitation decisions, individuals involved in decision-making and factors influencing decision-making. The results indicate that the main sanitation decisions are on investment, emptying, repair and cleaning. Landlords make investment, emptying and repair decisions, while tenants make cleaning decisions. Absentee landlords are less involved in most decision-making compared to live-in landlords, who rarely consult tenants in decision-making. Tenants make decisions after consultations with a third party and often collectively with other tenants. Sanitation interventions in informal settlements should thus, target landlords and tenants, with investment efforts being directed at landlords and maintenance efforts at tenants.

An opportunity cost model of subjective effort and task performance
Kurzban, Robert; Duckworth, Angela; Kable, Joseph W.; Myers, Justus
2013-01-01
Why does performing certain tasks cause the aversive experience of mental effort and concomitant deterioration in task performance? One explanation posits a physical resource that is depleted over time. We propose an alternate explanation that centers on mental representations of the costs and benefits associated with task performance. Specifically, certain computational mechanisms, especially those associated with executive function, can be deployed for only a limited number of simultaneous tasks at any given moment. Consequently, the deployment of these computational mechanisms carries an opportunity cost – that is, the next-best use to which these systems might be put. We argue that the phenomenology of effort can be understood as the felt output of these cost/benefit computations. In turn, the subjective experience of effort motivates reduced deployment of these computational mechanisms in the service of the present task. These opportunity cost representations, then, together with other cost/benefit calculations, determine effort expended and, everything else equal, result in performance reductions. In making our case for this position, we review alternate explanations both for the phenomenology of effort associated with these tasks and for performance reductions over time. Likewise, we review the broad range of relevant empirical results from across subdisciplines, especially psychology and neuroscience. We hope that our proposal will help to build links among the diverse fields that have been addressing similar questions from different perspectives, and we emphasize ways in which alternate models might be empirically distinguished.

[Correction Notice: An Erratum for this article was reported in Vol 28(10) of Psychological Assessment (see record 2016-22725-001). In the article, the penultimate sentence of the abstract should read “These results suggest that a significant percentage of those making a suspect effort will be diagnosed with ADHD using the most commonly employed assessment methods: an interview alone (71%); an interview and ADHD behavior rating scales combined (65%); and an interview, behavior rating scales, and most continuous performance tests combined (62%).” All versions of this article have been corrected.] This retrospective study examines how many adult patients would plausibly receive a diagnosis of attention-deficit/hyperactivity disorder (ADHD) if performance and symptom validity measures were not administered during neuropsychological evaluations. Five hundred fifty-four patients were extracted from an archival clinical dataset. A total of 102 were diagnosed with ADHD based on cognitive testing, behavior rating scales, effort testing, and clinical interview; 115 were identified as putting forth suspect effort in accordance with the Slick, Sherman, and Iverson (1999) criteria. From a clinical decision-making perspective, suspect effort and ADHD groups were nearly indistinguishable on ADHD behavior, executive function, and functional impairment rating scales, as well as on cognitive testing and key clinical interview questions. These results suggest that a significant percentage of those making a suspect effort will be diagnosed with ADHD using the most commonly employed assessment methods: an interview alone (71%); an interview and ADHD behavior rating scales combined (65%); and an interview, behavior rating scales, and most continuous performance tests combined (62%) [corrected].

Full Text Available The idea of automatic decision making approximating normatively optimal decisions without necessitating much cognitive effort is intriguing. Whereas recent findings support the notion that such fast, automatic processes explain empirical data well, little is known about the conditions under which such processes are selected rather than more deliberate stepwise strategies. We investigate the role of the format of information presentation, focusing explicitly on the ease of information acquisition and its influence on information integration processes. In a probabilistic inference task, the standard matrix employed in prior research was contrasted with a newly created map presentation format and additional variations of both presentation formats. Across three experiments, a robust presentation format effect emerged: Automatic decision making was more prevalent in the matrix (with high information accessibility, whereas sequential decision strategies prevailed when the presentation format demanded more information acquisition effort. Further scrutiny of the effect showed that it is not driven by the presentation format as such, but rather by the extent of information search induced by a format. Thus, if information is accessible with minimal need for information search, information integration is likely to proceed in a perception-like, holistic manner. In turn, a moderate demand for information search decreases the likelihood of behavior consistent with the assumptions of automatic decision making.

In Switzerland, the prevalence of medical end-of-life practices had been assessed on a population level only once - in 2001 - until in 2013/14 an identical study was conducted. We aimed to compare the results of the 2001 and 2013 studies with a special focus on shared decision-making and patients' decision-making capacity. Our study encompassed a 21.3% sample of deaths among residents of the German-speaking part of Switzerland aged 1 year or older. From 4998 mailed questionnaires, 3173 (63.5%) were returned. All data were weighted to adjust for age- and sex-specific differences in response rates. Cases with at least one reported end-of-life practice significantly increased from 74.5% (2001) to 82.3% (2013) of all deaths eligible for an end-of-life decision (p Switzerland, there remains potential for further improvement in shared decision-making. Efforts to motivate physicians to involve patients and relatives may be a win-win situation.

Risk-informing special treatment requirements for reactors
International Nuclear Information System (INIS)
McKenna, E.M.; Reed, T.A.
2001-01-01
The U.S. Nuclear Regulatory Commission (NRC) is proposing to make regulatory changes to the scope of structures, systems, and components (SSCs) requiring special treatment. ''Special treatment requirements'' refers to those specific examples of regulations that are applied in order to provide a high degree of assurance that SSC will be capable of performing their intended functions when needed. The current scope of SSCs covered by the special treatment requirements governing commercial nuclear reactors is deterministically based and stems primarily from the evaluation of selected design basis events, as described in updated final safety analysis reports (UFSARs). This regulatory framework provides reasonable assurance of no undue risk to the health and safety of the public. However, recent advances in technology, coupled with operating reactor experience, have suggested that an alternative approach that would use a risk-informed process for evaluating SSC safety significance, would, in turn, result in a more focused determination of which SSCs should receive special treatment requirements.

Medial Orbitofrontal Cortex Mediates Effort-related Responding in Rats.
Münster, Alexandra; Hauber, Wolfgang
2017-11-17
The medial orbitofrontal cortex (mOFC) is known to support flexible control of goal-directed behavior. However, limited evidence suggests that the mOFC also mediates the ability of organisms to work with vigor towards a selected goal, a hypothesis that received little consideration to date. Here we show that excitotoxic mOFC lesion increased responding under a progressive ratio (PR) schedule of reinforcement, that is, the highest ratio achieved, and increased the preference for the high effort-high reward option in an effort-related decision-making task, but left intact outcome-selective Pavlovian-instrumental transfer and outcome-specific devaluation. Moreover, pharmacological inhibition of the mOFC increased, while pharmacological stimulation reduced PR responding. In addition, pharmacological mOFC stimulation attenuated methylphenidate-induced increase of PR responding. Intact rats tested for PR responding displayed higher numbers of c-Fos positive mOFC neurons than appropriate controls; however, mOFC neurons projecting to the nucleus accumbens did not show a selective increase in neuronal activation implying that they may not play a major role in regulating PR responding. Collectively, these results suggest that the mOFC plays a major role in mediating effort-related motivational functions. Moreover, our data demonstrate for the first time that the mOFC modulates effort-related effects of psychostimulant drugs. © The Author 2017. Published by Oxford University Press.

Environmental Decision Making and Information Technology: Issues Assessment
Energy Technology Data Exchange (ETDEWEB)
Barg, S.; Fletcher, T.; Mechling, J.; Tonn, B.; Turner, R.
1999-05-01
This report presents a summary of the Information Technology and Environmental Decision Making Workshop that was held at Harvard University, October 1-3, 1998. Over sixty participants from across the US took part in discussions that focused on the current practice of using information technology to support environmental decision making and on future considerations of information technology development, information policies, and data quality issues in this area. Current practice is focusing on geographic information systems and visualization tools, Internet applications, and data warehousing. In addition, numerous organizations are developing environmental enterprise systems to integrate environmental information resources. Plaguing these efforts are issues of data quality (and public trust), system design, and organizational change. In the future, much effort needs to focus on building community-based environmental decision-making systems and processes, which will be a challenge given that exactly what needs to be developed is largely unknown and that environmental decision making in this arena has been characterized by a high level of conflict. Experimentation and evaluation are needed to contribute to efficient and effective learning about how best to use information technology to improve environmental decision making.

Behavioral Assessment of Listening Effort Using a Dual-Task Paradigm
Directory of Open Access Journals (Sweden)
Jean-Pierre Gagné
2017-01-01
Full Text Available Published investigations (n = 29 in which a dual-task experimental paradigm was employed to measure listening effort during speech understanding in younger and older adults were reviewed. A summary of the main findings reported in the articles is provided with respect to the participants’ age-group and hearing status. Effects of different signal characteristics, such as the test modality, on dual-task outcomes are evaluated, and associations with cognitive abilities and self-report measures of listening effort are described. Then, several procedural issues associated with the use of dual-task experiment paradigms are discussed. Finally, some issues that warrant future research are addressed. The review revealed large variability in the dual-task experimental paradigms that have been used to measure the listening effort expended during speech understanding. The differences in experimental procedures used across studies make it difficult to draw firm conclusions concerning the optimal choice of dual-task paradigm or the sensitivity of specific paradigms to different types of experimental manipulations. In general, the analysis confirmed that dual-task paradigms have been used successfully to measure differences in effort under different experimental conditions, in both younger and older adults. Several research questions that warrant further investigation in order to better understand and characterize the intricacies of dual-task paradigms were identified.

The administration of a glucose drink has been shown to enhance cognitive performance with effect sizes comparable with those from pharmaceutical interventions in human trials. In the memory domain, it is currently debated whether glucose facilitation of performance is due to differential targeting of hippocampal memory or whether task effort is a more important determinant. Using a placebo-controlled, double-blind, crossover 2(Drink: glucose/placebo) × 2(Effort: ± secondary task) design, 20 healthy young adults' recognition memory performance was measured using the 'remember-know' procedure. Two high effort conditions (one for each drink) included secondary hand movements during word presentation. A 25 g glucose or 30 mg saccharine (placebo) drink was consumed 10 min prior to the task. The presence of a secondary task resulted in a global impairment of memory function. There were significant Drink × Effort interactions for overall memory accuracy but no differential effects for 'remember' or 'know' responses. These data suggest that, in some circumstances, task effort may be a more important determinant of the glucose facilitation of memory effect than hippocampal mediation.

Studies on reproductive technologies often examine women's reproductive lives in terms of choice and control. Drawing on 48 accounts of procreative experiences of religiously devout Jewish women in Israel and the US, we examine their attitudes, understandings and experiences of pregnancy, reproductive technologies and prenatal testing. We suggest that the concept of hishtadlut-"obligatory effort"-works as an explanatory model that organizes Haredi women's reproductive careers and their negotiations of reproductive technologies. As an elastic category with negotiable and dynamic boundaries, hishtadlut gives ultra-orthodox Jewish women room for effort without the assumption of control; it allows them to exercise discretion in relation to medical issues without framing their efforts in terms of individual choice. Haredi women hold themselves responsible for making their obligatory effort and not for pregnancy outcomes. We suggest that an alternative paradigm to autonomous choice and control emerges from cosmological orders where reproductive duties constitute "obligatory choices."

Based on the quantum version of the postulates, we derive a transformation rule for velocity. This rule reduces to the Einstein's velocity-addition formula in the macroscopic limit and reveals an interesting aspect of time. The 3-D case, time-dilation effect, and invariant interval are also discussed in term of this new formulation. This is a preliminary investigation; some results are derived, while others are interesting observations at this point.

Full Text Available Decision-making is defined as a selection of a certain actionamong several alternatives. It is the essence of planning, asin the managerial sense there is no plan until a decision of engagementof resources, reputation and direction of activities ismade. Decision-making is, in fact, only a step in planning, evenwhen it is performed quickly and without special consideration.It is what we all experience every day. It is one of the most fascinatingbiological activities and the subject of frightening implicationsfor the whole human race. Since various techniques improvethe system and the quality of managerial decision-making,they are classified into three assumptions: risk analysis, decision-making trees, and the theory of revealed preference. Allof these are based on the interaction of a certain number of importantvariables out of which many contain the elements ofuncertainty, but maybe also high level of probability.

Respiratory effort from the photoplethysmogram.
Addison, Paul S
2017-03-01
The potential for a simple, non-invasive measure of respiratory effort based on the pulse oximeter signal - the photoplethysmogram or 'pleth' - was investigated in a pilot study. Several parameters were developed based on a variety of manifestations of respiratory effort in the signal, including modulation changes in amplitude, baseline, frequency and pulse transit times, as well as distinct baseline signal shifts. Thirteen candidate parameters were investigated using data from healthy volunteers. Each volunteer underwent a series of controlled respiratory effort maneuvers at various set flow resistances and respiratory rates. Six oximeter probes were tested at various body sites. In all, over three thousand pleth-based effort-airway pressure (EP) curves were generated across the various airway constrictions, respiratory efforts, respiratory rates, subjects, probe sites, and the candidate parameters considered. Regression analysis was performed to determine the existence of positive monotonic relationships between the respiratory effort parameters and resulting airway pressures. Six of the candidate parameters investigated exhibited a distinct positive relationship (poximeter probe and an ECG (P2E-Effort) and the other using two pulse oximeter probes placed at different peripheral body sites (P2-Effort); and baseline shifts in heart rate, (BL-HR-Effort). In conclusion, a clear monotonic relationship was found between several pleth-based parameters and imposed respiratory loadings at the mouth across a range of respiratory rates and flow constrictions. The results suggest that the pleth may provide a measure of changing upper airway dynamics indicative of the effort to breathe. Copyright © 2017 The Author. Published by Elsevier Ltd..

Making Healthy Choices Easier: Regulation versus Nudging.
Hansen, Pelle Guldborg; Skov, Laurits Rohden; Skov, Katrine Lund
2016-01-01
In recent years, the nudge approach to behavior change has emerged from the behavioral sciences to challenge the traditional use of regulation in public health strategies to address modifiable individual-level behaviors related to the rise of noncommunicable diseases and their treatment. However, integration and testing of the nudge approach as part of more comprehensive public health strategies aimed at making healthy choices easier are being threatened by inadequate understandings of its scientific character, its relationship with regulation, and its ethical implications. This article reviews this character and its ethical implication with a special emphasis on the compatibility of nudging with traditional regulation, special domains of experience, and the need for a more nuanced approach to the ethical debate. The aim is to advance readers' understanding and give guidance to those who have considered working with or incorporating the nudge approach into programs or policies aimed at making healthful choices easier.

Energy Technology Data Exchange (ETDEWEB)
Larson, G.S.
1995-12-31
Ten years have passed since the first regional low-level radioactive waste compacts received Congressional consent and initiated their efforts to develop new disposal capacity. During these 10 years, both significant achievements and serious setbacks have marked our efforts and affect our current outlook. Recent events in the waste marketplace, particularly in the operating status of the Barnwell disposal facility, have now raised legitimate questions about the continued rationale for the regional framework that grew out of the original legislation enacted by Congress in 1980. At the same time, licensing activities for new regional disposal facilities are under way in three states, and a fourth awaits the final go-ahead to begin construction. Uncertainty over the meaning and reliability of the marketplace events makes it difficult to gauge long-term implications. In addition, differences in the status of individual state and compact facility development efforts lead to varying assessments of the influence these events will, or should, have on such efforts.

Neuenschwander, D.E.; Turner, B.N.
1992-01-01
Maxwell's equations are obtained by generalizing the laws of magnetostatics, which follow from the Biot--Savart law and superposition, to be consistent with special relativity. The Lorentz force on a charged particle and its rate of energy change also follow by making Newton's second law for a particle in a magnetostatic field consistent with special relativity

Meaning making in cancer survivors: a focus group study.
Directory of Open Access Journals (Sweden)
Nadia van der Spek
Full Text Available BACKGROUND: Confrontation with a life-threatening disease like cancer can evoke existential distress, which can trigger a search for meaning in people after having survived this disease. METHODS: In an effort to gain more insight in the meaning making process, we conducted four focus groups with 23 cancer survivors on this topic. Participants responded to questions about experienced meaning making, perceived changes in meaning making after cancer and the perceived need for help in this area. RESULTS: Most frequently mentioned meaning making themes were relationships and experiences. We found that, in general, cancer survivors experienced enhanced meaning after cancer through relationships, experiences, resilience, goal-orientation and leaving a legacy. Some participants, however, also said to have (also experienced a loss of meaning in their lives through experiences, social roles, relationships and uncertainties about the future. CONCLUSIONS: The results indicated that there is a group of cancer survivors that has succeeded in meaning making efforts, and experienced sometimes even more meaning in life than before diagnosis, while there is also a considerable group of survivors that struggled with meaning making and has an unmet need for help with that. The results of this study contribute to develop a meaning centered intervention for cancer survivors.

Objective measures of listening effort: effects of background noise and noise reduction.
Sarampalis, Anastasios; Kalluri, Sridhar; Edwards, Brent; Hafter, Ervin
2009-10-01
This work is aimed at addressing a seeming contradiction related to the use of noise-reduction (NR) algorithms in hearing aids. The problem is that although some listeners claim a subjective improvement from NR, it has not been shown to improve speech intelligibility, often even making it worse. To address this, the hypothesis tested here is that the positive effects of NR might be to reduce cognitive effort directed toward speech reception, making it available for other tasks. Normal-hearing individuals participated in 2 dual-task experiments, in which 1 task was to report sentences or words in noise set to various signal-to-noise ratios. Secondary tasks involved either holding words in short-term memory or responding in a complex visual reaction-time task. At low values of signal-to-noise ratio, although NR had no positive effect on speech reception thresholds, it led to better performance on the word-memory task and quicker responses in visual reaction times. Results from both dual tasks support the hypothesis that NR reduces listening effort and frees up cognitive resources for other tasks. Future hearing aid research should incorporate objective measurements of cognitive benefits.

Westinghouse Owners Group Risk-Informed Regulation Efforts: Options 2 and 3
International Nuclear Information System (INIS)
Brown, Jason A.; Osterrieder, Robert A.; Lutz, Robert J.; Dingler, Maurice; Ward, Lewis A.
2002-01-01
The U.S. Nuclear Regulatory Commission (NRC) has initiated efforts to incorporate risk-informed methods to redefine the scope of the existing 10 CFR 50 regulations (Option 2) and to change the technical requirements of the regulations (Option 3). The overall objectives of these efforts are to enhance plant safety, provide a framework for risk-informed regulations, add flexibility to plant operations, and reduce regulatory burden. The Westinghouse Owners Group (WOG) has a variety of active programs in the risk-informed area, including a program in the Option 2 and Option 3 areas. These two programs will be summarized including the benefits and the technical approach. The purpose of Option 2 is to make changes to the overall scope of structures, systems and components (SSCs) covered by 10 CFR 50 requiring special treatment by formulating new risk-informed safety classification categories that are linked to current definitions of safety-related and important-to-safety. This initiative would permit possible changes to the current special treatment requirements based on risk insights. The Nuclear Energy Institute (NEI) has developed an Option 2 implementation guideline (NEI 00-04 Draft Revision B). The WOG has initiated a program to validate the NEI guideline and to provide an initial cost-benefit assessment of the revised categorization and treatment under Option 2 via trial application to two systems at both Surry Unit 1 and Wolf Creek. The WOG Option 2 program includes consideration of all of the components in the selected systems, regardless of whether or not they are modeled in the respective plant probabilistic risk assessment (PRA) studies. As a result, quantitative risk measures are not available for many of the components being considered. In this case, the WOG program will provide valuable input to the NEI guideline. Additionally, the WOG program extends the use of both of the dominant methodologies for risk-informed ISI (RI-ISI) to address repair and

Effort rights-based fisheries management (RBM) is less widely used than catch rights, whether for groups or individuals. Because RBM on catch or effort necessarily requires a total allowable catch (TAC) or total allowable effort (TAE), RBM is discussed in conjunction with issues in assessing fish...... populations and providing TACs or TAEs. Both approaches have advantages and disadvantages, and there are trade-offs between the two approaches. In a narrow economic sense, catch rights are superior because of the type of incentives created, but once the costs of research to improve stock assessments...

Olympic and world sport: making transnational society?
Giulianotti, Richard; Brownell, Susan
2012-06-01
This paper introduces the special issue of the British Journal of Sociology on the subject of the transnational aspects of Olympic and world sport. The special issue is underpinned by the perspective that because sport provides a space for the forging of transnational connections and global consciousness, it is increasingly significant within contemporary processes of globalization and the making of transnational society. In this article, we examine in turn eight social scientific themes or problems that are prominent within the special issue: globalization, glocalization, neo-liberal ideologies and policies, transnational society, securitization, global civil society, transnational/global public sphere, and fantasy/imagination. We conclude by highlighting five 'circles' of future research inquiry within world sport that should be explored by social scientists. © London School of Economics and Political Science 2012.

Thermal equilibrium and statistical thermometers in special relativity.
Cubero, David; Casado-Pascual, Jesús; Dunkel, Jörn; Talkner, Peter; Hänggi, Peter
2007-10-26
There is an intense debate in the recent literature about the correct generalization of Maxwell's velocity distribution in special relativity. The most frequently discussed candidate distributions include the Jüttner function as well as modifications thereof. Here we report results from fully relativistic one-dimensional molecular dynamics simulations that resolve the ambiguity. The numerical evidence unequivocally favors the Jüttner distribution. Moreover, our simulations illustrate that the concept of "thermal equilibrium" extends naturally to special relativity only if a many-particle system is spatially confined. They make evident that "temperature" can be statistically defined and measured in an observer frame independent way.

The purpose was to investigate the contribution of leg-muscle-generated forces to paddle force and kayak speed during maximal-effort flat-water paddling. Five elite male kayakers at national and international level participated. The participants warmed up at progressively increasing speeds and then performed a maximal-effort, nonrestricted paddling sequence. This was followed after 5 min rest by a maximal-effort paddling sequence with the leg action restricted--the knee joints "locked." Left- and right-side foot-bar and paddle forces were recorded with specially designed force devices. In addition, knee angular displacement of the right and left knees was recorded with electrogoniometric technique, and the kayak speed was calculated from GPS signals sampled at 5 Hz. The results showed that reduction in both push and pull foot-bar forces resulted in a reduction of 21% and 16% in mean paddle-stroke force and mean kayak speed, respectively. Thus, the contribution of foot-bar force from lower-limb action significantly contributes to kayakers' paddling performance.

Risk assessment and multi-criteria decision-making
International Nuclear Information System (INIS)
Segerstaahl, Boris
1989-01-01
Risk assessment and analysis is connected to the policy framework used in decision-making on issues concerning technological risk. A review of the problems created by different views concerning the fundamental structure of risk concepts is used as a way to describe the structure of risk assessment studies as used in decision-making. The fundamental difference between judgments based on assessments and on perceptions is analyzed in order to explain the dynamics of the decision making process. A proposed effort to study the energy sector as a dynamic endless game implementing a mixed strategy is suggested. (author)

EDITORIAL: Special issue on Graphene Special issue on Graphene
Morpurgo, Alberto F.; Trauzettel, Björn
2010-03-01
Since the revolutionary experimental discovery of graphene in the year 2004, research on this new two-dimensional carbon allotrope has progressed at a spectacular pace. The impact of graphene on different areas of research— including physics, chemistry, and applied sciences— is only now starting to be fully appreciated. There are different factors that make graphene a truly impressive system. Regarding nano-electronics and related fields, for instance, it is the exceptional electronic and mechanical properties that yield very high room-temperature mobility values, due to the particular band structure, the material `cleanliness' (very low-concentration of impurities), as well as its stiffness. Also interesting is the possibility to have a high electrical conductivity and optical transparency, a combination which cannot be easily found in other material systems. For other fields, other properties could be mentioned, many of which are currently being explored. In the first years following this discovery, research on graphene has mainly focused on the fundamental physics aspects, triggered by the fact that electrons in graphene behave as Dirac fermions due to their interaction with the ions of the honeycomb lattice. This direction has led to the discovery of new phenomena such as Klein tunneling in a solid state system and the so-called half-integer quantum Hall effect due to a special type of Berry phase that appears in graphene. It has also led to the appreciation of thicker layers of graphene, which also have outstanding new properties of great interest in their own right (e.g., bilayer graphene, which supports chiral quasiparticles that, contrary to Dirac electrons, are not massless). Now the time is coming to deepen our knowledge and improve our control of the material properties, which is a key aspect to take one step further towards applications. The articles in the Semiconductor Science and Technology Graphene special issue deal with a diversity of topics

Minimal-effort planning of active alignment processes for beam-shaping optics
Haag, Sebastian; Schranner, Matthias; Müller, Tobias; Zontar, Daniel; Schlette, Christian; Losch, Daniel; Brecher, Christian; Roßmann, Jürgen
2015-03-01
In science and industry, the alignment of beam-shaping optics is usually a manual procedure. Many industrial applications utilizing beam-shaping optical systems require more scalable production solutions and therefore effort has been invested in research regarding the automation of optics assembly. In previous works, the authors and other researchers have proven the feasibility of automated alignment of beam-shaping optics such as collimation lenses or homogenization optics. Nevertheless, the planning efforts as well as additional knowledge from the fields of automation and control required for such alignment processes are immense. This paper presents a novel approach of planning active alignment processes of beam-shaping optics with the focus of minimizing the planning efforts for active alignment. The approach utilizes optical simulation and the genetic programming paradigm from computer science for automatically extracting features from a simulated data basis with a high correlation coefficient regarding the individual degrees of freedom of alignment. The strategy is capable of finding active alignment strategies that can be executed by an automated assembly system. The paper presents a tool making the algorithm available to end-users and it discusses the results of planning the active alignment of the well-known assembly of a fast-axis collimator. The paper concludes with an outlook on the transferability to other use cases such as application specific intensity distributions which will benefit from reduced planning efforts.

Association of work-related stress with mental health problems in a special police force unit.
Garbarino, Sergio; Cuomo, Giovanni; Chiorri, Carlo; Magnavita, Nicola
2013-01-01
Law and order enforcement tasks may expose special force police officers to significant psychosocial risk factors. The aim of this work is to investigate the relationship between job stress and the presence of mental health symptoms while controlling sociodemographical, occupational and personality variables in special force police officers. At different time points, 292 of 294 members of the 'VI Reparto Mobile', a special police force engaged exclusively in the enforcement of law and order, responded to our invitation to complete questionnaires for the assessment of personality traits, work-related stress (using the Demand-Control-Support (DCS) and the Effort-Reward-Imbalance (ERI) models) and mental health problems such as depression, anxiety and burnout. Regression analyses showed that lower levels of support and reward and higher levels of effort and overcommitment were associated with higher levels of mental health symptoms. Psychological screening revealed 21 (7.3%) likely cases of mild depression (Beck Depression Inventory, BDI≥10). Officers who had experienced a discrepancy between work effort and rewards showed a marked increase in the risk of depression (OR 7.89, 95% CI 2.32 to 26.82) when compared with their counterparts who did not perceive themselves to be in a condition of distress. The findings of this study suggest that work-related stress may play a role in the development of mental health problems in police officers. The prevalence of mental health symptoms in the cohort investigated here was low, but not negligible in the case of depression. Since special forces police officers have to perform sensitive tasks for which a healthy psychological functioning is needed, the results of this study suggest that steps should be taken to prevent distress and improve the mental well-being of these workers.

Normal and Special Models of Neutrino Masses and Mixings
Altarelli, Guido
2005-01-01
One can make a distinction between "normal" and "special" models. For normal models $\\theta_{23}$ is not too close to maximal and $\\theta_{13}$ is not too small, typically a small power of the self-suggesting order parameter $\\sqrt{r}$, with $r=\\Delta m_{sol}^2/\\Delta m_{atm}^2 \\sim 1/35$. Special models are those where some symmetry or dynamical feature assures in a natural way the near vanishing of $\\theta_{13}$ and/or of $\\theta_{23}- \\pi/4$. Normal models are conceptually more economical and much simpler to construct. Here we focus on special models, in particular a recent one based on A4 discrete symmetry and extra dimensions that leads in a natural way to a Harrison-Perkins-Scott mixing matrix.

Background: There are a variety of proposed motivations for sport specialization, such as improving sport skills to an elite level, making all-star or travel teams, or receiving a scholarship or professional contract. However, there has not been a quantitative examination of the attitudes and beliefs that may be contributing to the trend of sport specialization and year-round sport participation. Purpose: The primary aim was to describe the attitudes and beliefs of youth club sport athletes regarding sport specialization and sport participation. A secondary objective was to investigate whether an association exists between the level of sport specialization and the belief in receiving a college scholarship. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 974 youth athletes (578 female; mean age, 14.2 ± 1.6 years) completed an anonymous questionnaire that focused on attitudes and beliefs toward sport specialization and sport participation. Questions were developed utilizing the feedback of a panel of content area experts and the University of Wisconsin Survey Center. Data were summarized using frequencies, proportions (%), and means ± SDs. Results: Fewer than half of all athletes (45.8%) believed that specialization increased their chances of getting injured either “quite a bit” or “a great deal.” However, 91% of athletes believed that specialization increased their chances of getting better at their sport either “quite a bit” or “a great deal.” Similarly, the majority of athletes believed that specialization increased their chances of making their high school team (80.9%) or a college team (66.9%) either “quite a bit” or “a great deal.” Overall, 15.7% of athletes believed that they were either “very” or “extremely” likely to receive a college scholarship based on athletic performance. Highly specialized athletes were nearly twice as likely to have a high belief in receiving a college scholarship

The purpose of this study was to examine the average treatment effect of preschool special education services on children's kindergarten academic skills. Using data from a nationally representative sample of United States children who participated in the Early Childhood Longitudinal Study-Birth Cohort, we examined the effectiveness of preschool special education services by comparing reading and math outcomes for children who received special education services at preschool-age to a propensity-score-weighted sample of children who did not receive these services. Results indicated that the receipt of these special education services had a statistically significant moderate negative effect on children's kindergarten skills in both reading (d=-0.21) and mathematics (d=-0.29). These findings have implications for the implementation and evaluation of services for young children experiencing developmental delays or disabilities.

Impacts of government and market on firm’s efforts to reduce pollution
Directory of Open Access Journals (Sweden)
Bowon Kim
2015-12-01
Full Text Available We examine how the government and the market affect firm’s pollution abatement efforts, i.e. firm’s efforts to reduce its pollution emission. The way for the government to control firm’s pollution is to impose penalty, whereas the consumers (the market make their purchasing decision by taking into account the pollution, i.e. the demand is affected by the stock of pollution. In effect, we consider two forces, government penalty and consumer’s sensitivity to pollution, as primary factors to control firm’s pollution and analyze their interaction in relation to the firm’s pollution reduction efforts. The analysis suggests as follows. The government penalty and the consumer’s awareness are substitutes either (1 when the market size is relatively large or (2 when the market is relatively small, but the government penalty is relatively heavy. On the contrary, the two factors are complements when the market size is relatively small and the government penalty is relatively light. We discuss managerial and economic implications of the analysis results.

2003-01-01
The assay of special nuclear material in the high level liquid waste streams assumes importance as this is the first stage in the extraction cycle and considerable losses of plutonium could occur here. This stream contains all the fission products as also the minor actinides and hence normal nuclear techniques cannot be used without prior separation of the special nuclear material. This paper presents the preliminary results carried out using wavelength dispersive x-ray fluorescence as part of the developmental efforts to assay SNM in these streams by instrumental techniques.

Cancer survivors' efforts at meaning making may influence the extent to which they successfully make meaning from their experience (i.e., experience posttraumatic growth, find life meaningful, and restore beliefs in a just world), which may, in turn, influence their psychological adjustment. Previous research regarding both meaning making processes and meanings made as determinants of adjustment has shown inconsistent effects, partly because of the lack of clearly articulated theoretical frameworks and problematic research strategies. In a 1-year longitudinal study, the authors distinguished the meaning making process from the outcomes of that process (meanings made), employing specific measures of both. The authors tested pathways through which meaning making efforts led to 3 different meanings made (growth, life meaning, and restored just-world belief) in a sample of 172 young to middle-age adult cancer survivors, and they explored whether those meanings made mediated the effect of meaning making efforts on psychological adjustment. Cross-sectional and longitudinal path models of the meaning making process indicate that meaning making efforts are related to better adjustment through the successful creation of adaptive meanings made from the cancer experience. The authors conclude with clinical implications and suggestions for future research. (c) 2008 APA, all rights reserved.

Neural basis of quasi-rational decision making.
Lee, Daeyeol
2006-04-01
Standard economic theories conceive homo economicus as a rational decision maker capable of maximizing utility. In reality, however, people tend to approximate optimal decision-making strategies through a collection of heuristic routines. Some of these routines are driven by emotional processes, and others are adjusted iteratively through experience. In addition, routines specialized for social decision making, such as inference about the mental states of other decision makers, might share their origins and neural mechanisms with the ability to simulate or imagine outcomes expected from alternative actions that an individual can take. A recent surge of collaborations across economics, psychology and neuroscience has provided new insights into how such multiple elements of decision making interact in the brain.

Design patterns offer many advantages for software development, but can introduce inefficiency into the final program. Program specialization can eliminate such overheads, but is most effective when targeted by the user to specific bottlenecks. Consequently, we propose that these concepts...... are complementary. Program specialization can optimize programs written using design patterns, and design patterns provide information about the program structure that can guide specialization. Concretely, we propose specialization patterns, which describe how to apply program specialization to optimize uses...... of design patterns. In this paper, we analyze the specialization opportunities provided by specific uses of design patterns. Based on the analysis of each design pattern, we define the associated specialization pattern.

Identify and describe information needs and associated goals of physicians, care coordinators, and families related to coordinating care for medically complex children and youth with special health care needs (CYSHCN). We conducted 19 in-depth interviews with physicians, care coordinators, and parents of CYSHCN following the Critical Decision Method technique. We analyzed the interviews for information needs posed as questions using a systematic content analysis approach and categorized the questions into information need goal types and subtypes. The Critical Decision Method interviews resulted in an average of 80 information needs per interview. We categorized them into 6 information need goal types: (1) situation understanding, (2) care networking, (3) planning, (4) tracking/monitoring, (5) navigating the health care system, and (6) learning, and 32 subtypes. Caring for CYSHCN generates a large amount of information needs that require significant effort from physicians, care coordinators, parents, and various other individuals. CYSHCN are often chronically ill and face developmental challenges that translate into intense demands on time, effort, and resources. Care coordination for CYCHSN involves multiple information systems, specialized resources, and complex decision-making. Solutions currently offered by health information technology fall short in providing support to meet the information needs to perform the complex care coordination tasks. Our findings present significant opportunities to improve coordination of care through multifaceted and fully integrated informatics solutions. © The Author 2017.

Examining human resources' efforts to develop a culturally competent workforce.
Whitman, Marilyn V; Valpuesta, Domingo
2010-01-01
The increasing diversification of the nation's population poses significant challenges in providing care that meets the needs of culturally diverse patients. Human resource management plays a vital role in developing a more culturally competent workforce. This exploratory study examines current efforts by human resource directors (HRDs) in Alabama's general hospitals to recruit more diverse candidates, train staff, and make language access resources available. A questionnaire was developed based on the Office of Minority Health's Culturally and Linguistically Appropriate Services standards. The HRDs of the 101 Alabama general hospitals served as the study's target population. A sample of 61 responses, or 60.4% of the population, was obtained. The findings indicate that most HRDs are focusing their efforts on recruiting racially/ethnically diverse candidates and training clerical and nursing staff to care for culturally and linguistically diverse patients. Less effort is being focused on recruiting candidates who speak a different language, and only 44.3% have a trained interpreter on the staff. The HRDs who indicated that they work closely with organizations that provide support to diverse groups were more likely to recruit diverse employees and have racially/ethnically and linguistically diverse individuals in leadership positions. It is crucial that health care organizations take the necessary steps to diversify their workforce to broaden access, improve the quality and equity of care, and capture a greater market share.

Reducing hazardous cleaning product use: a collaborative effort.
Pechter, Elise; Azaroff, Lenore S; López, Isabel; Goldstein-Gelb, Marcy
2009-01-01
Workplace hazards affecting vulnerable populations of low-wage and immigrant workers present a special challenge to the practice of occupational health. Unions, Coalition for Occupational Safety and Health (COSH) groups, and other organizations have developed worker-led approaches to promoting safety. Public health practitioners can provide support for these efforts. This article describes a successful multiyear project led by immigrant cleaning workers with their union, the Service Employees International Union (SEIU) Local 615, and with support from the Massachusetts COSH (MassCOSH) to address exposure to hazardous chemicals. After the union had identified key issues and built a strategy, the union and MassCOSH invited staff from the Massachusetts Department of Public Health's Occupational Health Surveillance Program (OHSP) to provide technical information about health effects and preventive measures. Results included eliminating the most hazardous chemicals, reducing the number of products used, banning mixing products, and improving safety training. OHSP's history of public health practice regarding cleaning products enabled staff to respond promptly. MassCOSH's staff expertise and commitment to immigrant workers allowed it to play a vital role.

Full Text Available Abstract Background The work of care for parents of children with complex special health care needs may be increasing, while excessive work demands may erode the quality of care. We sought to summarize knowledge and develop a general conceptual model of the work of care. Methods Systematic review of peer-reviewed journal articles that focused on parents of children with special health care needs and addressed factors related to the physical and emotional work of providing care for these children. From the large pool of eligible articles, we selected articles in a randomized sequence, using qualitative techniques to identify the conceptual components of the work of care and their relationship to the family system. Results The work of care for a child with special health care needs occurs within a dynamic system that comprises 5 core components: (1 performance of tasks such as monitoring symptoms or administering treatments, (2 the occurrence of various events and the pursuit of valued outcomes regarding the child's physical health, the parent's mental health, or other attributes of the child or family, (3 operating with available resources and within certain constraints (4 over the passage of time, (5 while mentally representing or depicting the ever-changing situation and detecting possible problems and opportunities. These components interact, some with simple cause-effect relationships and others with more complex interdependencies. Conclusions The work of care affecting the health of children with special health care needs and their families can best be understood, studied, and managed as a multilevel complex system.

Business continuity, emergency planning and special needs: How to protect the vulnerable.
Reilly, Daniel
2015-01-01
Emergencies and disasters affect all segments of the population. Some segments are more at risk during the emergency response and recovery efforts owing to vulnerabilities that increase the risk of harm. These vulnerabilities are due to individuals' disabilities, which must be incorporated into emergency and business continuity planning. Some disabilities are obvious, such as impaired vision, hearing or mobility, while other are less evident, but equally disabling, such as cognitive disorders, geographical or language isolation, and numerous age-related factors. Taken together when creating emergency or business continuity plans, the issues identified as disabilities can be grouped by functionality and termed as special needs. This paper will detail the identification of special needs populations, explain how these persons are vulnerable during the emergency or disaster response and recovery process, and provide examples of how to partner with individuals within identified special needs populations to improve the planning process.

Crustal permeability: Introduction to the special issue
Ingebritsen, Steven E.; Gleeson, Tom
2015-01-01
The topic of crustal permeability is of broad interest in light of the controlling effect of permeability on diverse geologic processes and also timely in light of the practical challenges associated with emerging technologies such as hydraulic fracturing for oil and gas production (‘fracking’), enhanced geothermal systems, and geologic carbon sequestration. This special issue of Geofluids is also motivated by the historical dichotomy between the hydrogeologic concept of permeability as a static material property that exerts control on fluid flow and the perspective of economic geologists, geophysicists, and crustal petrologists who have long recognized permeability as a dynamic parameter that changes in response to tectonism, fluid production, and geochemical reactions. Issues associated with fracking, enhanced geothermal systems, and geologic carbon sequestration have already begun to promote a constructive dialog between the static and dynamic views of permeability, and here we have made a conscious effort to include both viewpoints. This special issue also focuses on the quantification of permeability, encompassing both direct measurement of permeability in the uppermost crust and inferential permeability estimates, mainly for the deeper crust.

Biomechanical energy harvesting: generating electricity during walking with minimal user effort.
Donelan, J M; Li, Q; Naing, V; Hoffer, J A; Weber, D J; Kuo, A D
2008-02-08
We have developed a biomechanical energy harvester that generates electricity during human walking with little extra effort. Unlike conventional human-powered generators that use positive muscle work, our technology assists muscles in performing negative work, analogous to regenerative braking in hybrid cars, where energy normally dissipated during braking drives a generator instead. The energy harvester mounts at the knee and selectively engages power generation at the end of the swing phase, thus assisting deceleration of the joint. Test subjects walking with one device on each leg produced an average of 5 watts of electricity, which is about 10 times that of shoe-mounted devices. The cost of harvesting-the additional metabolic power required to produce 1 watt of electricity-is less than one-eighth of that for conventional human power generation. Producing substantial electricity with little extra effort makes this method well-suited for charging powered prosthetic limbs and other portable medical devices.

Proposed rulemaking to risk-inform special treatment requirements
International Nuclear Information System (INIS)
Reed, Timothy A.; McKenna, Eileen M.
2003-01-01
This paper presents the status of Nuclear Regulatory Commission (NRC) rulemaking efforts to risk-inform special treatment requirements that reside in Title 10 of the Code of Federal Regulations, 10 CFR Part 21, Part 50, and Part 100. The staff has prepared a proposed rulemaking to add a new section to 10 CFR Part 50 to provide an alternative set of requirements for treatment of structures, systems and components (SSCs), using a risk-informed categorization process to determine safety significance of the SSCs. These requirements can be voluntarily adopted by light-water reactor licensees and applicants. The proposed rule is based upon extensive interactions with stakeholders (including consideration of public comments on draft rule language made available on the NRC rulemaking web site), experience with pilot plants, and guidance development activities. The NRC staff expects that stakeholder input provided in response to the proposed rule issuance will be valuable and support the efforts to issue the final rule. (author)

Efforts toward enhancing seismic safety at Kashiwazaki Kariwa Nuclear Power Station
International Nuclear Information System (INIS)
Yamashita, Kazuhiko
2009-01-01
It has been two years since the Niigata-ken Chuetsu-oki Earthquake (NCOE) occurred in 2007. The earthquake brought a major disaster for Kashiwazaki, Kariwa, and the neighboring areas. First of all, we would like to give condolences to people in the devastated area and to pray for the immediate recovery. Our Kashiwazaki Kariwa Nuclear Power Station located in the same area was naturally caught up in the earthquake. The station was hit by a big tremor more than its intensity assumed to be valid at the station design stage. In spite of unexpected tremor, preventive functions for the station safety worked as expected as it designed. Critical facilities designed as high seismic class were not damaged, though considerable damages were seen in outside-facilities designed as low seismic class. We currently make efforts to inspect and recover damages. While we carefully carry out inspection and assessment to make sure the station integrity, we are also going forward restoration as well as construction for seismic safety enhancement in turn. This report introduces details of the following accounts, these are an outline of guidelines for seismic design evaluation that was revised in 2006, a situation at Kashiwazaki Kariwa Nuclear Power Station in the aftermath of the earthquake, and efforts toward enhancing seismic safety that the Tokyo Electric Power Company (TEPCO) has made since the seismic disaster, and our approach to evaluation of facility integrity.

Full Text Available Special education in Brazil is defined in law as “the type of education offered preferentially in the regular classes for students with special needs education”. However, this proposal of special education has not always been defined in this way, and a factor that contributed greatly to the consolidation of special education as a specific field of study was the research and theis resulting publications. Thus, this study aimed to make a scientometric analysis in the field of special education in order to determine which are and were the main trends of research over the years, and to review literature on the history of special education. It was felt that the issue of special education has undergone major advances, with consequent recovery of the subject with special needs. The scientometric analysis in special education to suggest that there has been a great evolution in the area, including a fact explained by the large number of papers published over time and the different aspects of his publications. Reflections on scientometrics in special education characterize the global production of special education and provide input for further research are made in this area. Thus, the construction and analysis of these indicators have provided input to view the state of the art in special education.

Incentive Design and Mis-Allocated Effort
Schnedler, Wendelin
2013-01-01
Incentives often distort behavior: they induce agents to exert effort but this effort is not employed optimally. This paper proposes a theory of incentive design allowing for such distorted behavior. At the heart of the theory is a trade-off between getting the agent to exert effort and ensuring that this effort is used well. The theory covers various moral-hazard models, ranging from traditional single-task to multi-task models. It also provides -for the first time- a formalization and proof...

The fifth section of our Special Task Force report identifies and discusses two aggregation issues: 1) aggregation of cost and benefit information across individuals to a population level for benefit plan decision making and 2) combining multiple elements of value into a single value metric for individuals. First, we argue that additional elements could be included in measures of value, but such elements have not generally been included in measures of quality-adjusted life-years. For example, we describe a recently developed extended cost-effectiveness analysis (ECEA) that provides a good example of how to use a broader concept of utility. ECEA adds two features-measures of financial risk protection and income distributional consequences. We then discuss a further option for expanding this approach-augmented CEA, which can introduce many value measures. Neither of these approaches, however, provide a comprehensive measure of value. To resolve this issue, we review a technique called multicriteria decision analysis that can provide a comprehensive measure of value. We then discuss budget-setting and prioritization using multicriteria decision analysis, issues not yet fully resolved. Next, we discuss deliberative processes, which represent another important approach for population- or plan-level decisions used by many health technology assessment bodies. These use quantitative information on CEA and other elements, but the group decisions are reached by a deliberative voting process. Finally, we briefly discuss the use of stated preference methods for developing "hedonic" value frameworks, and conclude with some recommendations in this area.

Full Text Available Accuracy in estimating the needed effort for software development caused software effort estimation to be a challenging issue. Beside estimation of total effort, determining the effort elapsed in each software development step is very important because any mistakes in enterprise resource planning can lead to project failure. In this paper, a Bayesian belief network was proposed based on effective components and software development process. In this model, the feedback loops are considered between development steps provided that the return rates are different for each project. Different return rates help us determine the percentages of the elapsed effort in each software development step, distinctively. Moreover, the error measurement resulted from optimized effort estimation and the optimal coefficients to modify the model are sought. The results of the comparison between the proposed model and other models showed that the model has the capability to highly accurately estimate the total effort (with the marginal error of about 0.114 and to estimate the effort elapsed in each software development step.

'Good-faith efforts' are enough to avoid punitive damages.
1999-07-23
The U.S. Supreme Court ruled that employers who make "good faith efforts" to comply with Federal civil rights laws cannot be forced to pay punitive damages for their managers' discriminatory conduct. [Name removed], an employee of the American Dental Association, sued her employer when she was passed over for a promotion. [Name removed] alleged sex discrimination under Title VII of the Civil Rights Act. Evidence showed that the employer rewrote a job description to favor a male candidate. To recover punitive damages, an employee must demonstrate that the employer acted with malice or reckless indifference. The Americans with Disabilities Act specifically uses Title VII with regard to discrimination, including its terms for punitive damages.

Aum Shinrikyo’s Nuclear and Chemical Weapons Development Efforts
Directory of Open Access Journals (Sweden)
Andrea A. Nehorayoff
2016-03-01
Full Text Available This article details the terrorist activities of the Japanese cult, Aum Shinrikyo, from the perspective of its complex engineering efforts aimed at producing nuclear and chemical weapons. The experience of this millenarian organization illustrates that even violent non-state actors with considerable wealth and resources at their disposal face numerous obstacles to realizing their destructive aspirations. Specifically, Aum’s attempts at complex engineering were stymied by a combination of unchecked fantastical thinking, self-imposed ideological constraints, and a capricious leadership. The chapter highlights each of these mechanisms, as well as the specific ways in which they constrained the decision-making process and the implementation of the complex engineering tasks associated with their unconventional weapons development.

People with severe and profound grade disabilities are the subject of interest in psychiatry, clinical psychology and special pedagogy. Unfortunately, the paradigmatic approach to special education based on postmodern philosophy is in contrast to the biomedical approach that is based on the positivist and Cartesian models. The paper is an attempt to systematize the similarities and differences between the humanistic approach and the modern biomedical model, which, despite the apparent differences, do not differ so much from each other. Work with a person disabled intellectually in the severe or profound degree is governed by the principles of methodical realism, taking into account to an equal extent the principal deficits, the concomitant diseases, limitations and the social context. The deeper the impairment and disability is, the smaller is the role of the humanistic paradigm in work with the client in the medical management and educational process. Changing the paradigms of special pedagogy has drawn attention to the social context of disability, separating, however, special pedagogy from modern medicine and psychology, cognitive-oriented and psychometry-based. The postmodern paradigm has become an ideology, which makes it difficult to work with deeply disabled people. Only the multidirectional approach including a variety of paradigms makes it possible to provide integrational aid to people with severe and profound grade intellectual disabilities. Working with such a disabled person should take into account equally the biomedical and humanistic aspects. © 2018 MEDPRESS.

Therefore, efforts variables are seen as the multistage dynamic variable, and venture investment principal-agent model with venture entrepreneurs having multistage efforts is constructed on the basis of the classic principal-agent theory in the paper. Further, in the later stage effort of venture entrepreneurs is affected by the size of prestage benefit with venture capitalists and venture entrepreneurs; thus the fairness preference model is improved, and venture investment principal-agent model with venture entrepreneurs having multistage efforts is constructed on the basis of fairness preference theory. Both theoretical derivation and simulation have demonstrated that, under the condition of information asymmetry, if the fairness preference of venture entrepreneurs holds, then (1 venture capitalists provide venture entrepreneurs with level higher than that without fairness preference, (2 in every single stage venture entrepreneurs make efforts higher than those without fairness preference, and (3 in two periods both venture investors and venture entrepreneurs gain total real gains higher than those in two periods without fair preference.

Introduction to the special issue: Intuition and affect in risk perception and decision making
Gisela Boehm; Wibecke Brun
2008-01-01
(from the introduction) Intuition and affect have been neglected topics in the literature on human judgment and decision making for a long time. Judgmental processes involved in risk perception and decision making have traditionally been conceptualized as cognitive in nature, being based upon a rational and deliberate evaluation of the alternatives at hand. This picture started to change in the early 1980s when decision researchers looked beyond rational, deliberate, and cognitive processes a...

Organizational decision making is dominated by teams. When an important decision is required, a team is often formed to make it or to advise the individual decision maker, because a team has more resources, knowledge, and political insight than any one individual working alone. As teams have become geographically distributed, collaboration technology has come to play an important role in such collective decision making efforts. Instant messaging (IM) is an increasingly prevalen...

Introduction to the special issue 'unintended effects of international cooperation'.
Koch, Dirk-Jan; Schulpen, Lau
2018-06-01
The 'Evaluation and Program Planning' journal has contributed to the launch of an academic discussion of unintended effects of international cooperation, notably by publishing in 2016 articles by Bamberger, Tarsilla, & Hesse-Biber and by Jabeen. This special issue aims to take up the academic challenges as laid down by those authors, by providing among others a clear typology and applying it, by outlining various methodological options and testing them, and elaborating on suggestions on how to deal with the barriers that prevent unintended effects being taken into account. This special issue makes clear that it is possible to reduce the share of unforeseen effects of international cooperation. Turning the spotlight on unintended effects that can be anticipated, and aiming to make progress on uncovering those that are particularly difficult to detect and debunking those that are exaggerated is the task that lies ahead of us.

Low-effort thought promotes political conservatism.
Eidelman, Scott; Crandall, Christian S; Goodman, Jeffrey A; Blanchar, John C
2012-06-01
The authors test the hypothesis that low-effort thought promotes political conservatism. In Study 1, alcohol intoxication was measured among bar patrons; as blood alcohol level increased, so did political conservatism (controlling for sex, education, and political identification). In Study 2, participants under cognitive load reported more conservative attitudes than their no-load counterparts. In Study 3, time pressure increased participants' endorsement of conservative terms. In Study 4, participants considering political terms in a cursory manner endorsed conservative terms more than those asked to cogitate; an indicator of effortful thought (recognition memory) partially mediated the relationship between processing effort and conservatism. Together these data suggest that political conservatism may be a process consequence of low-effort thought; when effortful, deliberate thought is disengaged, endorsement of conservative ideology increases.

Influences on Decision Making Identified by Parents of Children Receiving Pediatric Palliative Care.
Carroll, Karen W; Mollen, Cynthia J; Aldridge, Sarah; Hexem, Kari R; Feudtner, Chris
2012-01-01
Parental decision making is a critical component in the provision of palliative and end-of-life care, yet factors that parents perceive as influencing this process, when they are making decisions for their children, have not been well characterized. As part of a mixed-methods cohort study, we interviewed 73 parents of 50 pediatric patients who were referred to the hospital's pediatric palliative care service. The semistructured interviews focused on "decision making for your child"; the interviews were recorded and transcribed. A random sample (n = 13) was first coded and analyzed for core themes, and these themes were then cross-validated with a second random sample (n = 3) of interviews. Four dominant interrelated themes permeated parents' discussions about the decisions they were making for their children and the process of decision making. First, Orientation and Direction (including the subthemes of Goals and Hopes, Spirituality and Meaning, and Purposeful Effort) connotes the parents' effort to establish and clarify the broad context of decision making. Second, Defining What Is Good for the Child (including the subthemes of Quality of Life and Suffering, and Normalcy and Normalization) conveys how the parents posed questions and pondered what decisions would be in the child's best interests. Third, the entwined theme of Relationships, Communication, and Support reflects how parents reported the social and interactive nature of decision making. Fourth, the theme of Feelings and Personal Accountability focuses inward as parents report efforts to deal with their emotional responses and self-judgments. Parents report grappling with several influences upon their decision-making processes that extend well beyond the standard discussions of medical information exchanges and the evaluation of risks and benefits. Decision support for these parents should account for these diverse influences.

Making the clean available: Escaping India’s Chulha Trap
International Nuclear Information System (INIS)
Smith, Kirk R.; Sagar, Ambuj
2014-01-01
Solid cookfuel pollution is the largest energy-related health risk globally and most important cause of ill-health for Indian women and girls. At 700 million cooking with open biomass chulhas, the Indian population exposed has not changed in several decades, in spite of hundreds of programs to make the “available clean”, i.e. to burn biomass cleanly in advanced stoves. While such efforts continue, there is need to open up another front to attack this health hazard. Gas and electric cooking, which are clean at the household, are already the choice for one-third of Indians. Needed is a new agenda to make the “clean available”, i.e., to vigorously extend these clean fuels into populations that are caught in the Chulha Trap. This will require engaging new actors including the power and petroleum ministries as well as the ministry of health, which have not to date been directly engaged in addressing this problem. It will have implications for LPG imports, distribution networks, and electric and gas user technologies, as well as setting new priorities for electrification and biofuels, but at heart needs to be addressed as a health problem, not one of energy access, if it is to be solved effectively. - Highlights: • Pollution from cooking with solid fuels is largest health hazard for Indian women and girls. • 700 million Indians are caught in a trap using solid fuels with little change in number exposed for decades. • Efforts to make the biomass fuel clean through advanced stoves have made only modest progress in decades. • A major new effort is needed to make the clean available, in the form of gas and electricity. • This will require forging new partnerships and rethinking how these fuels are currently promoted

Partnering efforts at the Paducah Gaseous Diffusion Plant
International Nuclear Information System (INIS)
Warren, C.B.
1995-01-01
Before individuals or agencies can effectively work together to solve common problems, they must first agree on exactly what those problems are and establish common goals and methods that will lead to mutually acceptable solutions. Then, they must make a conscientious effort to form a cohesive team that focuses on the established goals and deemphasize traditional roles, which may in some instances be considered adversarial. This kind of teamwork/partnering process can be more difficult, though not impossible, to achieve in cases where there are traditional (real or imagined) adversarial relationships between the parties, i.e. regulator vs. regulated. The US Department of Energy Site Office (DOE) at Paducah, Kentucky, the Kentucky Department of Environmental Protection (KDEP) and the US Environmental Protection Agency, Region IV (EPA) have made t strides toward teamwork and partnering at DOE's Paducah Gaseous Diffusion Plant. They have accomplished this in a number of ways, which will be discussed in greater detail but first and foremost, the agencies agreed up front that they had mutual goals and interests. These goals are to protect public health and the environment in a cost-effective and timely manner, taking care to make the wisest use of public resources (tax dollars); to evaluate and minimize risks, and to achieve ''Win-Win'' for all parties concerned

A 'myth' for the special theory of relativity is presented as a series of questions and explanations of them. For example: Why can't one travel faster than light. The reason is that one can't go slower. There is only one speed. Everything is always moving at the speed of light; even if one is at rest in a chair. This is because one is moving through time. Other questions include; Why do clocks moving through space seem to run slower and slower as they travel faster and faster. If a spacecraft is moving through space at half the speed of light how fast would it be perceived moving through time. Why are there three space dimensions but only one time dimension. Why can movement be forward and backwards in space but only forward in time. Myths must explain what is found in nature and what is logically deduced from the myth must be found in nature. Supposing that the myth of special relativity is true makes calculations easier to do and the world easier to understand. (U.K.)

Reports an error in "The Impact of Failing to Identify Suspect Effort in Patients Undergoing Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Assessment" by Paul S. Marshall, James B. Hoelzle, Danielle Heyerdahl and Nathaniel W. Nelson ( Psychological Assessment , Advanced Online Publication, Jan 11, 2016, np). In the article, the penultimate sentence of the abstract should read “These results suggest that a significant percentage of those making a suspect effort will be diagnosed with ADHD using the most commonly employed assessment methods: an interview alone (71%); an interview and ADHD behavior rating scales combined (65%); and an interview, behavior rating scales, and most continuous performance tests combined (62%).” All versions of this article have been corrected. (The following abstract of the original article appeared in record 2016-00618-001.) This retrospective study examines how many adult patients would plausibly receive a diagnosis of attention-deficit/hyperactivity disorder (ADHD) if performance and symptom validity measures were not administered during neuropsychological evaluations. Five hundred fifty-four patients were extracted from an archival clinical dataset. A total of 102 were diagnosed with ADHD based on cognitive testing, behavior rating scales, effort testing, and clinical interview; 115 were identified as putting forth suspect effort in accordance with the Slick, Sherman, and Iverson (1999) criteria. From a clinical decision-making perspective, suspect effort and ADHD groups were nearly indistinguishable on ADHD behavior, executive function, and functional impairment rating scales, as well as on cognitive testing and key clinical interview questions. These results suggest that a significant percentage of those making a suspect effort will be diagnosed with ADHD using the most commonly employed assessment methods: an interview alone (71%); an interview and ADHD behavior rating scales combined (65%); and an interview, behavior

Motivation determines multiple aspects of behavior, including action selection and energization of behavior. Several components of the underlying neural systems have been examined closely, but the specific role of the different neuromodulatory systems in motivation remains unclear. Here, we compare directly the activity of dopaminergic neurons from the substantia nigra pars compacta and noradrenergic neurons from the locus coeruleus in monkeys performing a task manipulating the reward/effort trade-off. Consistent with previous reports, dopaminergic neurons encoded the expected reward, but we found that they also anticipated the upcoming effort cost in connection with its negative influence on action selection. Conversely, the firing of noradrenergic neurons increased with both pupil dilation and effort production in relation to the energization of behavior. Therefore, this work underlines the contribution of dopamine to effort-based decision making and uncovers a specific role of noradrenaline in energizing behavior to face challenges.

Depressed people show effort-related motivational symptoms, such as anergia, retardation, lassitude, and fatigue. Animal tests can model these motivational symptoms, and the present studies characterized the effort-related effects of the vesicular monoamine transport (VMAT-2) inhibitor tetrabenazine. Tetrabenazine produces depressive symptoms in humans and, at low doses, preferentially depletes dopamine. The current studies investigated the effects of tetrabenazine on effort-based decision making using the T-maze barrier task. Rats were tested in a T-maze in which the choice arms of the maze contain different reinforcement densities, and under some conditions, a vertical barrier was placed in the high-density arm to provide an effort-related challenge. The first experiment assessed the effects of tetrabenazine under different maze conditions: a barrier in the arm with 4 food pellets and 2 pellets in the no barrier arm (4-2 barrier), 4 pellets in one arm and 2 pellets in the other with no barrier in either arm (no barrier), and 4 pellets in the barrier arm with no pellets in the other (4-0 barrier). Tetrabenazine (0.25-0.75 mg/kg IP) decreased selection of the high cost/high reward arm when the barrier was present, but had no effect on choice under the no barrier and 4-0 barrier conditions. The effects of tetrabenazine on barrier climbing in the 4-2 condition were reversed by the adenosine A2A antagonist MSX-3 and the catecholamine uptake inhibitor and antidepressant bupropion. These studies have implications for the development of animal models of the motivational symptoms of depression and other disorders.

2016-03-01
Full Text Available Writing in English is one of the language skills that are taught in the context of learning English as a Foreign Language (EFL in Indonesian senior high schools. According to previous studies, most of the students consider writing is the most difficult of the four skills. This research was aimed at finding out the main difficulties in writing faced by the grade XI students at SMA Negeri 10 Fajar Harapan, Banda Aceh, and the efforts made by their teacher to overcome those problems. The design of this study was a descriptive qualitative study. To obtain the data, the writers used document collection and interviews. The results from the document collection showed that the highest percentages of problems faced by the students were in the aspect of language use and the least problems were in the aspect of content. The results from the interviews showed that the most common correcting efforts made by the teacher were giving written feedback for all aspects of writing i.e. language use, mechanics, vocabulary, organization, and content. Likewise, teachers need to develop systemized forms of feedback and make it clear to students what the feedback means and what they are to do with them to assist students in improving their writing skills.

Cutting agents for special metals
International Nuclear Information System (INIS)
Sugito, Seiji; Sakakibara, Fumi
1979-01-01
The quantity of use of special metals has increased year after year in the Plasma Research Institute, Nagoya University, with the development of researches on plasma and nuclear fusion. Most of these special metals are hard to cut, and in order to secure the surface smoothness and dimensional accuracy, considerable efforts are required. The method of experiment is as follows: cutting agents salt water and acetone, rape-seed oil, sulfide and chloride oil and water soluble cutting oil W grade 3; metals to be cut niobium, molybdenum, tantalum, titanium and tungsten; cutting conditions cutting speed 4.7 to 90 m/min, feed 0.07 to 0.2 mm/rev, depth of cut 0.1 to 0.4 mm, tool cemented carbide bit. Chemicals such as tetrachloromethane and trichloroethane give excellent cutting performance, but the toxicity is intense and the stimulative odor exists, accordingly they are hard to use practically. Cutting was easier when the salt water added with acetone was used than the case of rape-seed oil, but salt water is corrosive. Recently, the machining of molybdenum has been often carried out, and the water soluble cutting oil was the best. It is also good for cutting stainless steel, and its lubricating property is improved by adding some additives such as sulfur, chlorine, phosphorus and molybdenum disulfide. However after cutting with it, washing is required. (Kako, I.)

As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

1984-01-01
This is presented as basic data for making a mockup of the bronchus. Tubercluosis is an infectious disease designated by law and efforts to conquer it are exerted nationally. Whether the patient is infected or not can be diagnosed by photo fluorography intended for groups and also by Radio graphing which enables people to observe the film which is as long as the object. It is important to take photographs for the purpose of compacting as much information as possible in a film. But it is more important to gather information about the living bodies in the photographed film. Therefore, Knowledge of anatomy is most important for the accurate diagnosis of tuberculosis. Blood vessels of the lungs and the bronchus have a very complicated structure, so that they require efforts to understand them. To make a mockup of the bronchus is needed for better understanding of the complicated structure of the blood vessels in the lungs and the bronchus. I wrote this because I thought making a mockup is a foundation to understand the anatomy of the lungs

diverted into the Porong River through a mud pump system. Also we continuously monitor changes in eruption behavior and try to anticipate the consequences, particularly after the Ring Dyke (of main vent) collapsed and became useless in controlling the flow. In September 2009 spectacular eruption intensity with kick and wave developed and is continuing. Surface and subsurface investigations continue ceaselessly to try to understand the forces driving the eruption. There are no precedents for mitigation of such a large scale mud volcano in a densely populated area that seems destined to continue for a very long time. This makes all efforts to stop eruption together with the emergency efforts, which have to be conducted simultaneously with recovery and reconstruction efforts that cover all basic needs of people live in the area. This is why BPLS has to develop innovative and creative efforts, mainly by applying the basic principle of learning by doing.

2009-11-01
Full Text Available As other media, computer games convey messages which have tow features: explicit and implicit. Semiologically studying computer games and comparing them with narrative structures, the present study attempts to discover the messages they convey. Therefore we have studied and decoded “Special operation 85” as a semiological text. Results show that the game’s features, as naming, interests and motivations of the engaged people, and the events narrated, all lead the producers to their goals of introducing and publicizing Iranian-Islamic cultural values. Although this feature makes “Special Opreation 85” a unique game, it fails in its attempt to produce a mythical personage in Iranian-Islamic cultural context.

Local public opposition to federal bureaucratic decisions has resulted in public agencies rethinking the role of stakeholders in decision making. Efforts to include stakeholders directly in the decision-making process are on the increase. Unfortunately, many attempts to involve members of the public in decisions involving complex technical issues have failed. A key problem has been defining a meaningful role for the public in the process of arriving at a technical decision. This paper describes a successful effort by Sandia National Laboratories (SNL) in New Mexico to involve stakeholders in an important technical decision associated with its Environmental Restoration (ER) Project. The decision was where to locate a Corrective Action Management Unit (CAMU), a facility intended to consolidate and store wastes generated from the cleanup of hazardous waste sites. A formal priority setting process known as the Laboratory Integration Prioritization System (LIPS) was adapted to provide an approach for involving the public. Although rarely applied to stakeholder participation, the LIPS process proved surprisingly effective. It produced a consensus over a selected site and enhanced public trust and understanding of Project activities

Full Text Available Despite unprecedented access to information and diffusion of knowledge across the globe, the bulk of work in mainstream psychological science still reflects and promotes the interests of a privileged minority of people in affluent centers of the modern global order. Compared to other social science disciplines, there are few critical voices who reflect on the Euro-American colonial character of psychological science, particularly its relationship to ongoing processes of domination that facilitate growth for a privileged minority but undermine sustainability for the global majority. Moved by mounting concerns about ongoing forms of multiple oppression (including racialized violence, economic injustice, unsustainable over-development, and ecological damage, we proposed a special thematic section and issued a call for papers devoted to the topic of "decolonizing psychological science". In this introduction to the special section, we first discuss two perspectives—liberation psychology and cultural psychology—that have informed our approach to the topic. We then discuss manifestations of coloniality in psychological science and describe three approaches to decolonization—indigenization, accompaniment, and denaturalization—that emerge from contributions to the special section. We conclude with an invitation to readers to submit their own original contributions to an ongoing effort to create an online collection of digitally linked articles on the topic of decolonizing psychological science.

SERVIR Support to NSDI Efforts in Mesoamerica, Africa and the Himalayas
Delgado, Francisco
2014-01-01
SERVIR is a joint effort between NASA, USAID to build or improve capacities in developing regions to help adaptation to climate change by taking advantage of Earth Observation data for decision making. The project began in 2004, in Mesoamerica, partnering with the Central American Commission for Environment and Development(CCAD), the World Bank and CATHALAC. CATHALAC, located in Panama, serves as the regional hub for Mesoamerica since 2005. Two additional regional hubs have been established (in Easters & Western Africa - at RCMRD, Kenya, and The Himalayas- at ICIMOD, Nepal), and two more regional hubs are soon to be launched.

Effort Estimation in BPMS Migration
Directory of Open Access Journals (Sweden)
Christopher Drews
2018-04-01
Full Text Available Usually Business Process Management Systems (BPMS are highly integrated in the IT of organizations and are at the core of their business. Thus, migrating from one BPMS solution to another is not a common task. However, there are forces that are pushing organizations to perform this step, e.g. maintenance costs of legacy BPMS or the need for additional functionality. Before the actual migration, the risk and the effort must be evaluated. This work provides a framework for effort estimation regarding the technical aspects of BPMS migration. The framework provides questions for BPMS comparison and an effort evaluation schema. The applicability of the framework is evaluated based on a simplified BPMS migration scenario.

Given the far-reaching changes of modern working life, psychosocial stress at work has received increased attention. Its influence on stress-related disease risks is analysed with the help of standardised measurements based on theoretical models. Two such models have gained special prominence in recent years, the demand-control model and the effort-reward imbalance model. The former model places its emphasis on a distinct combination of job characteristics, whereas the latter model's focus is on the imbalance between efforts spent and rewards received in turn. The predictive power of these models with respect to coronary or cardiovascular disease and depression was tested in a number of prospective epidemiological investigations. In summary, twofold elevated disease risks are observed. Effects on cardiovascular disease are particularly pronounced among men, whereas no gender differences are observed for depression. Additional evidence derived from experimental and ambulatory monitoring studies supplements this body of findings. Current scientific evidence justifies an increased awareness and assessment of these newly discovered occupational risks, in particular by occupational health professionals. Moreover, structural and interpersonal measures of stress prevention and health promotion at work are warranted, with special emphasis on gender differences.

Dopamine, behavioral economics, and effort
Directory of Open Access Journals (Sweden)
John D Salamone
2009-09-01
Full Text Available Abstract. There are numerous problems with the hypothesis that brain dopamine (DA systems, particularly in the nucleus accumbens, directly mediate the rewarding or primary motivational characteristics of natural stimuli such as food. Research and theory related to the functions of mesolimbic DA are undergoing a substantial conceptual restructuring, with the traditional emphasis on hedonia and primary reward yielding to other concepts and lines of inquiry. The present review is focused upon the involvement of nucleus accumbens DA in behavioral activation and effort-related processes. Viewed from the framework of behavioral economics, the effects of accumbens DA depletions and antagonism on food-reinforced behavior are highly dependent upon the work requirements of the instrumental task, and DA depleted rats are more sensitive to increases in response costs (i.e., ratio requirements. Moreover, interference with accumbens DA transmission exerts a powerful influence over effort-related choice behavior. Rats with accumbens DA depletions or antagonism reallocate their instrumental behavior away from food-reinforced tasks that have high response requirements, and instead these rats select a less-effortful type of food-seeking behavior. Nucleus accumbens DA and adenosine interact in the regulation of effort-related functions, and other brain structures (anterior cingulate cortex, amygdala, ventral pallidum also are involved. Studies of the brain systems regulating effort-based processes may have implications for understanding drug abuse, as well as energy-related disorders such as psychomotor slowing, fatigue or anergia in depression and other neurological disorders.

Psychostimulant abuse has been linked to impairments in cost-benefit decision making. We assessed the effects of repeated amphetamine (AMPH) treatment in rodents on two distinct forms of decision making. Separate groups of rats were trained for 26 days on either a probabilistic (risk) or effort-discounting task, each consisting of four discrete blocks of ten choice trials. One lever always delivered a smaller reward (one or two pellets), whereas another lever delivered a four-pellet reward. For risk-discounting, the probability of receiving the larger reward decreased across trial blocks (100-12.5%), whereas on the effort task, four pellets could be obtained after a ratio of presses that increased across blocks (2-20). After training, rats received 15 saline or AMPH injections (escalating from 1 to 5 mg/kg) and were then retested during acute and long-term withdrawal. Repeated AMPH administration increased risky choice 2-3 weeks after drug exposure, whereas these treatments did not alter effort-based decision making in a separate group of animals. However, prior AMPH exposure sensitized the effects of acute AMPH on both forms of decision making, whereby lower doses were effective at inducing "risky" and "lazy" patterns of choice. Repeated AMPH exposure leads to relatively long-lasting increases in risky choice, as well as sensitization to the effects of acute AMPH on different forms of cost/benefit decision making. These findings suggest that maladaptive decision-making processes exhibited by psychostimulant abusers may be caused in part by repeated drug exposure.

Despite considerable policy efforts, women continue to be underrepresented in positions of power and decision making. As an important aspect of women empowerment, we examine women's participation in intrahousehold financial decision making and how this is affected by financial literacy. Using both OLS and IV regression analysis, we show that women with higher financial literacy are more involved in household financial decisions. In line with the literature, we further find that women are less...

Reason, emotion and decision-making: risk and reward computation with feeling
Quartz, Steven R.
2009-01-01
Many models of judgment and decision-making posit distinct cognitive and emotional contributions to decision-making under uncertainty. Cognitive processes typically involve exact computations according to a cost-benefit calculus, whereas emotional processes typically involve approximate, heuristic processes that deliver rapid evaluations without mental effort. However, it remains largely unknown what specific parameters of uncertain decision the brain encodes, the extent to which these parame...

To close the childhood immunization gap, we need a richer understanding of parents' decision-making.
Corben, Paul; Leask, Julie
2016-12-01
Vaccination is widely acknowledged as one of the most successful public health interventions globally and in most high-income countries childhood vaccination coverage rates are moderately high. Yet in many instances, immunisation rates remain below aspirational targets and have shown only modest progress toward those targets in recent years, despite concerted efforts to improve uptake. In part, coverage rates reflect individual parents' vaccination attitudes and decisions and, because vaccination decision-making is complex and context-specific, it remains challenging at individual and community levels to assist parents to make positive decisions. Consequently, in the search for opportunities to improve immunisation coverage, there has been a renewed research focus on parents' decision-making. This review provides an overview of the literature surrounding parents' vaccination decision-making, offering suggestions for where efforts to increase vaccination coverage should be targeted and identifying areas for further research.

ERP implementation projects have received enormous attention in the last years, due to their importance for organisations, as well as the costs and risks involved. The estimation of effort and costs associated with new projects therefore is an important topic. Unfortunately, there is still a lack of models that can cope with the special characteristics of these projects. As the main focus lies in adapting and customising a complex system, and even changing the organisation, traditional models like COCOMO can not easily be applied. In this article, we will apply effort estimation based on social choice in this context. Social choice deals with aggregating the preferences of a number of voters into a collective preference, and we will apply this idea by substituting the voters by project attributes. Therefore, instead of supplying numeric values for various project attributes, a new project only needs to be placed into rankings per attribute, necessitating only ordinal values, and the resulting aggregate ranking can be used to derive an estimation. We will describe the estimation process using a data set of 39 projects, and compare the results to other approaches proposed in the literature.

Distribution of Bottom Trawling Effort in the Yellow Sea and East China Sea.
Directory of Open Access Journals (Sweden)
Shengmao Zhang
Full Text Available Bottom trawling is one of the most efficient fishing activities, but serious and persistent ecological issues have been observed by fishers, scientists and fishery managers. Although China has applied the Beidou fishing vessel position monitoring system (VMS to manage trawlers since 2006, little is known regarding the impacts of trawling on the sea bottom environments. In this study, continuous VMS data of the 1403 single-rig otter trawlers registered in the Xiangshan Port, 3.9% of the total trawlers in China, were used to map the trawling effort in 2013. We used the accumulated distance (AD, accumulated power distance (APD, and trawling intensity as indexes to express the trawling efforts in the Yellow Sea (YS and East China Sea (ECS. Our results show that all three indexes had similar patterns in the YS and ECS, and indicated a higher fishing effort of fishing grounds that were near the port. On average, the seabed was trawled 0.73 times in 2013 over the entire fishing region, and 51.38% of the total fishing grounds were with no fishing activities. Because of VMS data from only a small proportion of Chinese trawlers was calculated fishing intensity, more VMS data is required to illustrate the overall trawling effort in China seas. Our results enable fishery managers to identify the distribution of bottom trawling activities in the YS and ECS, and hence to make effective fishery policy.

A special manifold is an allowed target manifold for the vector multiplets of D=4, N=2 supergravity. These manifolds are of interest for string theory because the moduli spaces of Calabi-Yau threefolds and c=9, (2,2) conformal field theories are special. Previous work has given a local, coordinate-dependent characterization of special geometry. A global description of special geometries is given herein, and their properties are studied. A special manifold M of complex dimension n is characterized by the existence of a holomorphic Sp(2n+2,R)xGL(1,C) vector bundle over M with a nowhere-vanishing holomorphic section Ω. The Kaehler potential on M is the logarithm of the Sp(2n+2,R) invariant norm of Ω. (orig.)

For many decades, research in judgment and decision making has examined behavioral violations of rational choice theory. In that framework, rationality is expressed as a single correct decision shared by experimenters and subjects that satisfies internal coherence within a set of preferences and beliefs. Outside of psychology, social scientists are now debating the need to modify rational choice theory with behavioral assumptions. Within psychology, researchers are debating assumptions about errors for many different definitions of rationality. Alternative frameworks are being proposed. These frameworks view decisions as more reasonable and adaptive that previously thought. For example, "rule following." Rule following, which occurs when a rule or norm is applied to a situation, often minimizes effort and provides satisfying solutions that are "good enough," though not necessarily the best. When rules are ambiguous, people look for reasons to guide their decisions. They may also let their emotions take charge. This chapter presents recent research on judgment and decision making from traditional and alternative frameworks.

Balancing emotion and cognition: a case for decision aiding in conservation efforts.
Wilson, Robyn S
2008-12-01
Despite advances in the quality of participatory decision making for conservation, many current efforts still suffer from an inability to bridge the gap between science and policy. Judgment and decision-making research suggests this gap may result from a person's reliance on affect-based shortcuts in complex decision contexts. I examined the results from 3 experiments that demonstrate how affect (i.e., the instantaneous reaction one has to a stimulus) influences individual judgments in these contexts and identified techniques from the decision-aiding literature that help encourage a balance between affect-based emotion and cognition in complex decision processes. In the first study, subjects displayed a lack of focus on their stated conservation objectives and made decisions that reflected their initial affective impressions. Value-focused approaches may help individuals incorporate all the decision-relevant objectives by making the technical and value-based objectives more salient. In the second study, subjects displayed a lack of focus on statistical risk and again made affect-based decisions. Trade-off techniques may help individuals incorporate relevant technical data, even when it conflicts with their initial affective impressions or other value-based objectives. In the third study, subjects displayed a lack of trust in decision-making authorities when the decision involved a negatively affect-rich outcome (i.e., a loss). Identifying shared salient values and increasing procedural fairness may help build social trust in both decision-making authorities and the decision process.

Visual cues and listening effort: individual variability.
Picou, Erin M; Ricketts, Todd A; Hornsby, Benjamin W Y
2011-10-01
To investigate the effect of visual cues on listening effort as well as whether predictive variables such as working memory capacity (WMC) and lipreading ability affect the magnitude of listening effort. Twenty participants with normal hearing were tested using a paired-associates recall task in 2 conditions (quiet and noise) and 2 presentation modalities (audio only [AO] and auditory-visual [AV]). Signal-to-noise ratios were adjusted to provide matched speech recognition across audio-only and AV noise conditions. Also measured were subjective perceptions of listening effort and 2 predictive variables: (a) lipreading ability and (b) WMC. Objective and subjective results indicated that listening effort increased in the presence of noise, but on average the addition of visual cues did not significantly affect the magnitude of listening effort. Although there was substantial individual variability, on average participants who were better lipreaders or had larger WMCs demonstrated reduced listening effort in noise in AV conditions. Overall, the results support the hypothesis that integrating auditory and visual cues requires cognitive resources in some participants. The data indicate that low lipreading ability or low WMC is associated with relatively effortful integration of auditory and visual information in noise.

The rate of environmental niche evolution describes the capability of species to explore the available environmental space and is known to vary among species owing to lineage-specific factors. Trophic specialization is a main force driving species evolution and is responsible for classical examples of adaptive radiations in fishes. We investigate the effect of trophic specialization on the rate of environmental niche evolution in the damselfish, Pomacentridae, which is an important family of tropical reef fishes. First, phylogenetic niche conservatism is not detected in the family using a standard test of phylogenetic signal, and we demonstrate that the environmental niches of damselfishes that differ in trophic specialization are not equivalent while they still overlap at their mean values. Second, we estimate the relative rates of niche evolution on the phylogenetic tree and show the heterogeneity among rates of environmental niche evolution of the three trophic groups. We suggest that behavioural characteristics related to trophic specialization can constrain the evolution of the environmental niche and lead to conserved niches in specialist lineages. Our results show the extent of influence of several traits on the evolution of the environmental niche and shed new light on the evolution of damselfishes, which is a key lineage in current efforts to conserve biodiversity in coral reefs.

Recent accomplishments in the intraval project a status report on validation efforts
International Nuclear Information System (INIS)
Nicholson, T.J.
1991-01-01
The INTRAVAL Project is an integrated international effort dealing with validation of geosphere transport models which began in October 1987. Its purpose and scope developed from two earlier projects, INTRACOIN and HYDRCOIN, which focused on assessment of transport and ground-water flow models, respectively. The unique aspect to INTRAVAL is the active interaction between the experimentalists and modelers simulating the selected test cases for examining model validation issues. The test cases selected consist of laboratory and field transport experiments and natural analogue studies that incorporate hydrogeologic and geochemical processes relevant to safety assessments of radioactive waste disposal. These test cases cover a range of spatial and temporal scales, hydrogeologic conditions and media for various radionuclide transport phenomena. The success to date has centered on the selection, documentation, simulation and analysis of these 17 test cases. The sharing of ideas on development and testing of conceptual models employed by the various 25 project teams in their simulations of specific test cases has begun the evolution of a validation strategy. The conceptualization of ground-water flow and radionuclide transport through various media is being actively tested using these specially selected, and in certain cases specifically designed, data sets. A second set of test cases are under development for an additional three-year Phase II effort to build on the successes of the Phase I work. 16 refs

Recognition in Programmes for Children with Special Needs
Directory of Open Access Journals (Sweden)
Marjeta Šmid
2016-09-01
Full Text Available The purpose of this article is to examine the factors that affect the inclusion of pupils in programmes for children with special needs from the perspective of the theory of recognition. The concept of recognition, which includes three aspects of social justice (economic, cultural and political, argues that the institutional arrangements that prevent ‘parity of participation’ in the school social life of the children with special needs are affected not only by economic distribution but also by the patterns of cultural values. A review of the literature shows that the arrangements of education of children with special needs are influenced primarily by the patterns of cultural values of capability and inferiority, as well as stereotypical images of children with special needs. Due to the significant emphasis on learning skills for academic knowledge and grades, less attention is dedicated to factors of recognition and representational character, making it impossible to improve some meaningful elements of inclusion. Any participation of pupils in activities, the voices of the children, visibility of the children due to achievements and the problems of arbitrariness in determining boundaries between programmes are some such elements. Moreover, aided by theories, the actions that could contribute to better inclusion are reviewed. An effective approach to changes would be the creation of transformative conditions for the recognition and balancing of redistribution, recognition, and representation.

Greater effort increases perceived value in an invertebrate.
Czaczkes, Tomer J; Brandstetter, Birgit; di Stefano, Isabella; Heinze, Jürgen
2018-05-01
Expending effort is generally considered to be undesirable. However, both humans and vertebrates will work for a reward they could also get for free. Moreover, cues associated with high-effort rewards are preferred to low-effort associated cues. Many explanations for these counterintuitive findings have been suggested, including cognitive dissonance (self-justification) or a greater contrast in state (e.g., energy or frustration level) before and after an effort-linked reward. Here, we test whether effort expenditure also increases perceived value in ants, using both classical cue-association methods and pheromone deposition, which correlates with perceived value. In 2 separate experimental setups, we show that pheromone deposition is higher toward the reward that requires more effort: 47% more pheromone deposition was performed for rewards reached via a vertical runway (high effort) compared with ones reached via a horizontal runway (low effort), and deposition rates were 28% higher on rough (high effort) versus smooth (low effort) runways. Using traditional cue-association methods, 63% of ants trained on different surface roughness, and 70% of ants trained on different runway elevations, preferred the high-effort related cues on a Y maze. Finally, pheromone deposition to feeders requiring memorization of one path bifurcation was up to 29% higher than to an identical feeder requiring no learning. Our results suggest that effort affects value perception in ants. This effect may stem from a cognitive process, which monitors the change in a generalized hedonic state before and after reward.

Fuzzy Bi-level Decision-Making Techniques: A Survey
Directory of Open Access Journals (Sweden)
Guangquan Zhang
2016-04-01
Full Text Available Bi-level decision-making techniques aim to deal with decentralized management problems that feature interactive decision entities distributed throughout a bi-level hierarchy. A challenge in handling bi-level decision problems is that various uncertainties naturally appear in decision-making process. Significant efforts have been devoted that fuzzy set techniques can be used to effectively deal with uncertain issues in bi-level decision-making, known as fuzzy bi-level decision-making techniques, and researchers have successfully gained experience in this area. It is thus vital that an instructive review of current trends in this area should be conducted, not only of the theoretical research but also the practical developments. This paper systematically reviews up-to-date fuzzy bi-level decisionmaking techniques, including models, approaches, algorithms and systems. It also clusters related technique developments into four main categories: basic fuzzy bi-level decision-making, fuzzy bi-level decision-making with multiple optima, fuzzy random bi-level decision-making, and the applications of bi-level decision-making techniques in different domains. By providing state-of-the-art knowledge, this survey paper will directly support researchers and practitioners in their understanding of developments in theoretical research results and applications in relation to fuzzy bi-level decision-making techniques.

ENABLING SMART MANUFACTURING TECHNOLOGIES FOR DECISION-MAKING SUPPORT
Helu, Moneer; Libes, Don; Lubell, Joshua; Lyons, Kevin; Morris, KC
2017-01-01
Smart manufacturing combines advanced manufacturing capabilities and digital technologies throughout the product lifecycle. These technologies can provide decision-making support to manufacturers through improved monitoring, analysis, modeling, and simulation that generate more and better intelligence about manufacturing systems. However, challenges and barriers have impeded the adoption of smart manufacturing technologies. To begin to address this need, this paper defines requirements for data-driven decision making in manufacturing based on a generalized description of decision making. Using these requirements, we then focus on identifying key barriers that prevent the development and use of data-driven decision making in industry as well as examples of technologies and standards that have the potential to overcome these barriers. The goal of this research is to promote a common understanding among the manufacturing community that can enable standardization efforts and innovation needed to continue adoption and use of smart manufacturing technologies.

How Firms Substitute for Authority in Strategic Decision-Making
DEFF Research Database (Denmark)
Dobrajska, Magdalena; Billinger, Stephan; Becker, Markus C.
Strategic decisions are often made by multiple organizational members who form decision-making structures specialized for a given strategic decision. We study a series of strategic decisions in a business unit of a global Fortune 500 firm, identifying for each decision the hierarchical...... takes place in response to changes in decision characteristics, including decision complexity, decision importance, CEO proximity, and the degree to which a decision is routine. We show various manifestations of the substitution mechanism and discuss implications for strategic decision-making....... and departmental positions of all participating organizational members. We find that firms substitute between different structural components in decision-making structures to combine hierarchical authority with cross-departmental coordination and redundant knowledge. This substitution between structural components...

Division of labour and the evolution of extreme specialization.
Cooper, Guy A; West, Stuart A
2018-05-28
Division of labour is a common feature of social groups, from biofilms to complex animal societies. However, we lack a theoretical framework that can explain why division of labour has evolved on certain branches of the tree of life but not others. Here, we model the division of labour over a cooperative behaviour, considering both when it should evolve and the extent to which the different types should become specialized. We found that: (1) division of labour is usually-but not always-favoured by high efficiency benefits to specialization and low within-group conflict; and (2) natural selection favours extreme specialization, where some individuals are completely dependent on the helping behaviour of others. We make a number of predictions, several of which are supported by the existing empirical data, from microbes and animals, while others suggest novel directions for empirical work. More generally, we show how division of labour can lead to mutual dependence between different individuals and hence drive major evolutionary transitions, such as those to multicellularity and eusociality.

Sex differences in the effects of juvenile and adult diet on age-dependent reproductive effort.
Houslay, T M; Hunt, J; Tinsley, M C; Bussière, L F
2015-05-01
Sexual selection should cause sex differences in patterns of resource allocation. When current and future reproductive effort trade off, variation in resource acquisition might further cause sex differences in age-dependent investment, or in sensitivity to changes in resource availability over time. However, the nature and prevalence of sex differences in age-dependent investment remain unclear. We manipulated resource acquisition at juvenile and adult stages in decorated crickets, Gryllodes sigillatus, and assessed effects on sex-specific allocation to age-dependent reproductive effort (calling in males, fecundity in females) and longevity. We predicted that the resource and time demands of egg production would result in relatively consistent female strategies across treatments, whereas male investment should depend sharply on diet. Contrary to expectations, female age-dependent reproductive effort diverged substantially across treatments, with resource-limited females showing much lower and later investment in reproduction; the highest fecundity was associated with intermediate lifespans. In contrast, long-lived males always signalled more than short-lived males, and male age-dependent reproductive effort did not depend on diet. We found consistently positive covariance between male reproductive effort and lifespan, whereas diet altered this covariance in females, revealing sex differences in the benefits of allocation to longevity. Our results support sex-specific selection on allocation patterns, but also suggest a simpler alternative: males may use social feedback to make allocation decisions and preferentially store resources as energetic reserves in its absence. Increased calling effort with age therefore could be caused by gradual resource accumulation, heightened mortality risk over time, and a lack of feedback from available mates. © 2015 European Society For Evolutionary Biology.

Full Text Available Objectives: During the past decades, cosmetic surgery has become increasingly popular. The purpose of this study is to make questionnaire for screening patients with negative body image in cosmetic clinics for special need people. Methods: In the present study, 150 special need people in cosmetic clinics were randomly assigned to fill questionnaires for assessing body area concerns. Results: Results of reliability analysis and validity have shown the effectiveness of this questionnaire for recognizing individuals with having negative body image. These preliminary results suggest that body dysmorphic disorder may be relatively common among patients seeking cosmetic surgery. Discussion: A high proportion of participants in cosmetic clinics have demonstrated significant body image concerns. These relatively common body image concerns deserve more study in adolescents and people with special needs.

Beyond communication - research as communicating: making user and audience studies matter - paper 2
Directory of Open Access Journals (Sweden)
Brenda Dervin
2006-01-01
Full Text Available Introduction. This is the written version of the keynote address (Making user studies matter: Thank you Mister Feynman and Monsieur Foucault delivered by senior author Dervin. The paper is linked to the Invited Paper in this issue and like that paper, reports on a project involving a dialogue between researchers and practitioners in library and information science, human computer interaction, and communication focusing on gaps in our understandings of users and audiences as well as in our efforts to collaborate with each other to conduct and apply research to the design and implementation of information, library, communication, and media systems. Argument. Our main conclusion in Paper 1 was that the traditional modes used for communication in social science research are not doing the job for user and audience studies. We set out five propositions relating to this conclusion: (1 the traditional modes of communicating in the research enterprise are not working; (2 Do the social sciences matter? Some serious and fundamental attacks; (3 a call to focus on the special problematics of the social sciences: agency, structure, power and the good; (4 eschewing scientific recipes and scholarly creeds and bringing back the joys of adventuring and muddling; (5 the paradox of communicatingfreedom is another word for nothing left to lose. Conclusion. We argue for shared dialogue in communicating across the three fields studied here: this will introduce uncertainty, but, rather than relying upon 'authority', the individual will be encouraged through the exploration of that uncertainty, to make their own sense of the offerings of others.

Has Malaysia's antidrug effort been effective?
Scorzelli, J F
1992-01-01
It is a common belief that a massive effort in law enforcement, preventive education and rehabilitation will result in the elimination of a country's drug problem. Based on this premise. Malaysia in 1983 implemented such a multifaceted anti-drug strategy, and the results of a 1987 study by the author suggested that Malaysia's effort had begun to contribute to a steady decrease in the number of identified drug abusers. Although the number of drug-addicted individuals declined, the country's recidivism rates were still high. Because of this high relapse rate, Malaysia expanded their rehabilitation effort and developed a community transition program. In order to determine the impact of these changes on the country's battle against drug abuse, a follow-up study was conducted in 1990. The results of this study did not clearly demonstrate that the Malaysian effort had been successful in eliminating the problem of drug abuse, and raised some questions concerning the effectiveness of the country's drug treatment programs.

Capacity for Preferences: Respecting Patients with Compromised Decision-Making.
Wasserman, Jason Adam; Navin, Mark Christopher
2018-05-01
When a patient lacks decision-making capacity, then according to standard clinical ethics practice in the United States, the health care team should seek guidance from a surrogate decision-maker, either previously selected by the patient or appointed by the courts. If there are no surrogates willing or able to exercise substituted judgment, then the team is to choose interventions that promote a patient's best interests. We argue that, even when there is input from a surrogate, patient preferences should be an additional source of guidance for decisions about patients who lack decision-making capacity. Our proposal builds on other efforts to help patients who lack decision-making capacity provide input into decisions about their care. For example, "supported," "assisted," or "guided" decision-making models reflect a commitment to humanistic patient engagement and create a more supportive process for patients, families, and health care teams. But often, they are supportive processes for guiding a patient toward a decision that the surrogate or team believes to be in the patient's medical best interests. Another approach holds that taking seriously the preferences of such a patient can help surrogates develop a better account of what the patient's treatment choices would have been if the patient had retained decision-making capacity; the surrogate then must try to integrate features of the patient's formerly rational self with the preferences of the patient's currently compromised self. Patients who lack decision-making capacity are well served by these efforts to solicit and use their preferences to promote best interests or to craft would-be autonomous patient images for use by surrogates. However, we go further: the moral reasons for valuing the preferences of patients without decision-making capacity are not reducible to either best-interests or (surrogate) autonomy considerations but can be grounded in the values of liberty and respect for persons.

Project-oriented teaching model about specialized courses in the information age
Chen, Xiaodong; Wang, Jinjiang; Tian, Qingguo; Wang, Yi; Cai, Huaiyu
2017-08-01
Specialized courses play a significant role in the usage of basic knowledge in the practical application for engineering college students. The engineering data available has sharply increased since the beginning of the information age in the 20th century, providing much more approaches to study and practice. Therefore, how to guide students to make full use of resources for active engineering practice learning has become one of the key problems for specialized courses. This paper took the digital image processing course for opto-electronic information science and technology major as an example, discussed the teaching model of specialized course in the information age, put forward the "engineering resource oriented model", and fostered the ability of engineering students to use the basic knowledge to innovate and deal with specific project objectives. The fusion of engineering examples into practical training and teaching encourages students to practice independent engineering thinking.

Full Text Available Education is envisaged as an important tool for the socio-economic and cultural development of an individual and acts as a catalyst for the pace of the development of the country. Keeping this in view, the Government of India has launched several programmes for the promotion of the education among the children as well as adults in the country. But, due to the malnutrition, superstitions, fluoride in the water, diseases like polio etc., natural calamities and other adverse conditions some children are becoming disabled. The place of the differently abled in the Indian society is lower when compared with the normal children as there is a notion that their disability is due to curse for the sins in the previous birth etc. and they were deprived in all spheres of life including education. To mainstream them on par with the normal population and to make them as partners of the pace of development of the country, the Government of India from time to time launched several programmes and started special schools. Sarva Shiksha Abhiyan is one of the programme implemented to create barrier free environment in the school and to promote inclusive education for the children with special needs (CWSN as one of the components.

Completing an advance directive offers individuals the opportunity to make informed choices about end-of-life care. However, these decisions could be influenced in different ways depending on how the information is presented. We randomly presented 185 participants with four distinct types of advance directive: neutrally framed (as reference), negatively framed, religiously framed, and a combination. Participants were asked which interventions they would like to receive at the end of life. Between 60% and 70% of participants responded "accept the special interventions" on the reference form. However, the majority (70%-90%) chose "refuse the interventions" on the negative form. With respect to the religious form, 70% to 80% chose "not decided yet." Participants who refused special life-sustaining treatments were older, female, and with better prior knowledge about advance directives. Our findings imply that the specific content of advance directives could affect decision-making with regard to various interventions for end-of-life care.

Needs for Risk Informing Environmental Cleanup Decision Making - 13613
International Nuclear Information System (INIS)
Zhu, Ming; Moorer, Richard
2013-01-01
This paper discusses the needs for risk informing decision making by the U.S. Department of Energy (DOE) Office of Environmental Management (EM). The mission of the DOE EM is to complete the safe cleanup of the environmental legacy brought about from the nation's five decades of nuclear weapons development and production and nuclear energy research. This work represents some of the most technically challenging and complex cleanup efforts in the world and is projected to require the investment of billions of dollars and several decades to complete. Quantitative assessments of health and environmental risks play an important role in work prioritization and cleanup decisions of these challenging environmental cleanup and closure projects. The risk assessments often involve evaluation of performance of integrated engineered barriers and natural systems over a period of hundreds to thousands of years, when subject to complex geo-environmental transformation processes resulting from remediation and disposal actions. The requirement of resource investments for the cleanup efforts and the associated technical challenges have subjected the EM program to continuous scrutiny by oversight entities. Recent DOE reviews recommended application of a risk-informed approach throughout the EM complex for improved targeting of resources. The idea behind this recommendation is that by using risk-informed approaches to prioritize work scope, the available resources can be best utilized to reduce environmental and health risks across the EM complex, while maintaining the momentum of the overall EM cleanup program at a sustainable level. In response to these recommendations, EM is re-examining its work portfolio and key decision making with risk insights for the major sites. This paper summarizes the review findings and recommendations from the DOE internal reviews, discusses the needs for risk informing the EM portfolio and makes an attempt to identify topics for R and D in integrated

With the dawn of planetary exploration, the international science community expressed concerns regarding the potential contamination of habitable planetary environments by the introduction of terrestrial organisms on robotic spacecraft. The initial concern was that such contamination would confound our efforts to find unambiguous evidence of life elsewhere in the Solar System, although, more recently, this concern has been expanded to include ethical considerations regarding the need to protect alien biospheres from potentially harmful and irreversible contamination. The international agreements which address this concern include the UN Space Treaty of 1967 and the Planetary Protection Policy of the International Council for Science's Committee on Space Research (COSPAR). In the context of Mars exploration, COSPAR calls a potentially habitable environment a 'Special Region', which it defines as: "A region within which terrestrial organisms are likely to propagate, or a region which is interpreted to have a high potential for the existence of extant Martian life forms." Specifically included in this definition are regions where liquid water is present or likely to occur and the Martian polar caps. Over the years, scientists have debated the level of cleanliness required for robotic spacecraft to investigate such environments with the goal of defining international standards that are strict enough to ensure the integrity of life-detection efforts during the period of 'biological exploration', which has been somewhat arbitrarily defined as 50 years from the arrival date of any given mission. More recently, NASA and ESA have adopted a definition of Special Regions as any Martian environment where liquid water is likely to exist within the next 500 years. While this appears to be a more conservative interpretation of the original COSPAR definition, it specifically excludes some environments where there is a high probability of liquid water on timescales greater than 500

How Useful Are Climate Projections for Adaptation Decision Making?
Smith, J. B.; Vogel, J. M.
2011-12-01
Decision making is often portrayed as a linear process that assumes scientific knowledge is a necessary precursor to effective policy and is used directly in policy making. Yet, in practice, the use of scientific information in decision making is more complex than the linear model implies. The use of climate projections in adaptation decision making is a case in point. This paper briefly reviews efforts by some decision makers to understand climate change risks and to apply this knowledge when making decisions on management of climate sensitive resources and infrastructure . In general, and in spite of extensive efforts to study climate change at the regional and local scale to support decision making, few decisions outside of adapting to sea level rise appear to directly apply to climate change projections. A number of U.S. municipalities and states, including Seattle, New York City, Phoenix, and the States of California and Washington, have used climate change projections to assess their vulnerability to various climate change impacts. Some adaptation decisions have been made based on projections of sea level rise, such as change in location of infrastructure. This may be because a future rise is sea level is virtually certain. In contrast, decision making on precipitation has been more limited, even where there is consensus on likely changes in sign of the variable. Nonetheless, decision makers are adopting strategies that can be justified based on current climate and climate variability and that also reduce risks to climate change. A key question for the scientific community is whether improved projections will add value to decision making. For example, it remains unclear how higher-resolution projections can change decision making as long as the sign and magnitude of projections across climate models and downscaling techniques retains a wide range of uncertainty. It is also unclear whether even better information on the sign and magnitude of change would

D.K. Morton
2012-09-01
In 1999, an international collaborative initiative for the development of advanced (Generation IV) reactors was started. The idea behind this effort was to bring nuclear energy closer to the needs of sustainability, to increase proliferation resistance, and to support concepts able to produce energy (both electricity and process heat) at competitive costs. The U.S. Department of Energy has supported this effort by pursuing the development of the Next Generation Nuclear Plant, a high temperature gas-cooled reactor. This support has included research and development of pertinent data, initial regulatory discussions, and engineering support of various codes and standards development. This report discusses the various applicable American Society of Mechanical Engineers (ASME) codes and standards that are being developed to support these high temperature gascooled reactors during construction and operation. ASME is aggressively pursuing these codes and standards to support an international effort to build the next generation of advanced reactors so that all can benefit.

Brazing of special metallic materials and material combinations using a special material
International Nuclear Information System (INIS)
Lison, R.
1981-01-01
The special materials include metals of groups IVa, Va and VIa of the periodic tables and their alloys. Their particular properties have won them applications in many highly specialized industries. For these materials to be used, mastery of thermal joining methods appropriate to their characteristics is necessary. High-temperature brazing is one such method for joining special materials. This paper presents variants of this technique suitable for each individual special material. Compatibility tests between various brazing metals and various special materials have been carried out by simulating the temperature/time cycle involved in brazing procedures. Special materials are relatively expensive, and their special properties are not required at every point in a structure: elsewhere they can be replaced by a different special material or by other metals or alloys. This means that joints must be made between two special materials or between a special material and a conventional material. When certain conditions are fulfilled, such joins can be made by high-temperature brazing. This paper also shows the extent to which the geometry of the join determines the choice of process. Example of applications are also given. (orig.)

Pocket money and child effort at school
François-Charles Wolff; Christine Barnet-Verzat
2008-01-01
In this paper, we study the relationship between the provision of parental pocket and the level of effort undertaken by the child at school. Under altruism, an increased amount of parental transfer should reduce the child's effort. Our empirical analysis is based on a French data set including about 1,400 parent-child pairs. We find that children do not undertake less effort when their parents are more generous.

Plan A: Off the shelf; Plan B: Make it yourself
International Nuclear Information System (INIS)
Westbrook, J.L.
1996-01-01
When there is radiological work to be done, you hope to be able to purchase, readily and cheaply, items for use in doing the work. But if there is no vendor who sells a product for your need, then you have to improvise. Similarly, particular kinds of services may not be available and sometimes even if a product or service is available, the lead time is such that you have to find some way to make do in the meantime. At Oak Ridge National Laboratory, we have had to devise a number of open-quotes make-it-yourselfclose quotes items and methods because of our specialized current facilities, several one-of-a-kind retired facilities, and the odd unusual situation that pops up-and because we have had practically every isotope from A to Z here. Several of these items and methods will be described, including the special shields and timesaving devices used for transuranic work, a cask for moving very hot pins, and ad hoc check sources

Stretch-sensitive paresis and effort perception in hemiparesis.
Vinti, Maria; Bayle, Nicolas; Hutin, Emilie; Burke, David; Gracies, Jean-Michel
2015-08-01
In spastic paresis, stretch applied to the antagonist increases its inappropriate recruitment during agonist command (spastic co-contraction). It is unknown whether antagonist stretch: (1) also affects agonist recruitment; (2) alters effort perception. We quantified voluntary activation of ankle dorsiflexors, effort perception, and plantar flexor co-contraction during graded dorsiflexion efforts at two gastrocnemius lengths. Eighteen healthy (age 41 ± 13) and 18 hemiparetic (age 54 ± 12) subjects performed light, medium and maximal isometric dorsiflexion efforts with the knee flexed or extended. We determined dorsiflexor torque, Root Mean Square EMG and Agonist Recruitment/Co-contraction Indices (ARI/CCI) from the 500 ms peak voluntary agonist recruitment in a 5-s maximal isometric effort in tibialis anterior, soleus and medial gastrocnemius. Subjects retrospectively reported effort perception on a 10-point visual analog scale. During gastrocnemius stretch in hemiparetic subjects, we observed: (1) a 25 ± 7 % reduction of tibialis anterior voluntary activation (maximum reduction 98 %; knee extended vs knee flexed; p = 0.007, ANOVA); (2) an increase in dorsiflexion effort perception (p = 0.03, ANCOVA). Such changes did not occur in healthy subjects. Effort perception depended on tibialis anterior recruitment only (βARI(TA) = 0.61, p hemiparesis, voluntary ability to recruit agonist motoneurones is impaired--sometimes abolished--by antagonist stretch, a phenomenon defined here as stretch-sensitive paresis. In addition, spastic co-contraction increases effort perception, an additional incentive to evaluate and treat this phenomenon.

It has been shown that the anterior cingulate cortex (ACC) and its dopamine system are crucial for decision making that requires physical/emotional effort, but not for all forms of cost-benefit decision making. Previous studies had mostly employed behavioral tasks with two competing cost-reward options that were preset by the experimenters. However, few studies have been conducted using scenarios in which the subjects have full control over the energy/time expenditure required to obtain a proportional reward. Here, we assessed the roles of the ACC and its dopamine system in cost-benefit decision making by utilizing a "do more get more" (DMGM) task and a time-reward trade-off (TRTO) task, wherein the animals were able to self-determine how much effort or time to expend at a nosepoke operandum for a proportional reward. Our results showed that (1) ACC inactivation severely impaired DMGM task performance, with a reduction in the rate of correct responses and a decrease in the effort expended, but did not affect the TRTO task; and (2) blocking ACC D2 receptors had no impact on DMGM task performance in the baseline cost-benefit scenario, but it significantly reduced the attempts to invest increased effort for a large reward when the benefit-cost ratio was reduced by half. In contrast, blocking ACC D1 receptors had no effect on DMGM task performance. These findings suggest that the ACC is required for self-paced effort-based but not for time-reward trade-off decision making. Furthermore, ACC dopamine D2 but not D1 receptors are involved in DMGM decision making.

Effort over the last decade to make radioecology stronger and sustainable within Europe crystallized in the creation of the European Radioecology Alliance. The first step for this integrative effort was the establishment of a network of excellence (NoE) under the EU FP7 Strategy for Allied Radioecology (STAR www.star-radioecology.org) project which commenced in 2011. One of the project objectives was to share knowledge of European radioecological capabilities. To help achieve this, a register of these capabilities at each of the STAR laboratories has been created. An Infrastructure Database was designed and programmed using web 2.0 technologies on a 'wiki' platform. Its intended use was to identify what assets were held and where improvements could be made. Information collated includes an inventory of the radioanalytical or conventional equipment and methods, bio-informatics equipment and methods, sample and data archives held, and models and codes used. It also provides a summary of the radioecological expertise of the 170 radio-ecologists at STAR institutes whose knowledge is wide-ranging and encompasses: atmospheric dispersion, dosimetry, ecology, ecotoxicology, environmental radiation protection, environmental surveillance, foodstuffs, terrestrial, freshwater and marine radioecology, modelling, radiobiology and radionuclide analyses, emergency preparedness, education and training, amongst others. In 2013, the EU FP7 Coordination and implementation of a pan-European instrument for radioecology (COMET, www.comet-radioecology.org) project, involving the STAR partners and additionally one Japanese and two Ukrainian research institutes, was initiated. The capabilities of these additional partners will be added to the database in 2014. The aim of the database was to gather information to: - avoid duplication of effort and thereby increase efficiency, - improve synergy and collaboration between the STAR project partners and others involved in

Orff-Schulwerk in Special Education: A Case Study
Directory of Open Access Journals (Sweden)
Maria Filianou
2013-12-01
Full Text Available In the school year 2012-2013 a cross-curricular programme was designed by a class teacher and a music teacher in a school for children with special needs in Athens, Greece. The programme was based on the Carl Orff approach. The purpose of this article is to show the advantages and the effectiveness of the elemental music and movement approach when applied in a group of students with special educational needs in a public school for special education. The motivation of the cooperating teachers in selecting this specific group stemmed from the particular challenges that they were facing. The first challenge was the lack of homogeneity among the students. There were children with mental deficiencies, pervasive developmental disorders (autism and rare syndromes. The second challenge was that the programme focused on only one specific topic that sought to acquaint children with their body and how to relate to it through space and time. The final challenge was the use of music and movement as the main means of achieving the goals of this programme. The goals were both musical and non-musical. The outcomes of the programme were thought to be positive by both teachers. The students worked in a group and their cooperation increased progressively during the programme. They showed progress not only cognitively but also psychokinetically and socially. At the end of the school year, their progress was marked by their participation in the school festival, in a performance of music and movement, which was the result of their efforts all year.

Major clean-up effort in the ATLAS cavern
Marzio Nessi
On Tuesday 10 October, 58 ATLAS collaborators volunteered to give a hand for a major clean-up of the ATLAS detector prior to the toroid magnet ramp-up. This special task monopolised all of the technical coordination team and eight supervisors to oversee the volunteers who were assigned to two separate five-hour shifts. The volunteers removed all sorts of loose material inside and outside the detector, focusing mainly on potentially magnetic material lost inside the detector and dirt accumulated over several months, not to mention zillions of clipped cable ties! The technical crew provided 120 garbage bags and all were used. All sorts of material that had been lost inside the detector by various people was retrieved, in particular small tools which could potentially damage the detector, as well as metallic fillings hazardous for the electronics once the magnet will be ramped up. A more detailed inspection followed for all the inside of the detector, making sure the current on the magnet could be raised to 5KA ...

Full Text Available To make good decisions, humans need to learn about and integrate different sources of appetitive and aversive information. While serotonin has been linked to value-based decision-making, its role in learning is less clear, with acute manipulations often producing inconsistent results. Here, we show that when the effects of a selective serotonin reuptake inhibitor (SSRI, citalopram are studied over longer timescales, learning is robustly improved. We measured brain activity with functional magnetic resonance imaging (fMRI in volunteers as they performed a concurrent appetitive (money and aversive (effort learning task. We found that 2 weeks of citalopram enhanced reward and effort learning signals in a widespread network of brain regions, including ventromedial prefrontal and anterior cingulate cortex. At a behavioral level, this was accompanied by more robust reward learning. This suggests that serotonin can modulate the ability to learn via a mechanism that is independent of stimulus valence. Such effects may partly underlie SSRIs' impact in treating psychological illnesses. Our results highlight both a specific function in learning for serotonin and the importance of studying its role across longer timescales.

Collaborative decision-making and promoting treatment adherence in pediatric chronic illness
Directory of Open Access Journals (Sweden)
Dennis Drotar
2010-03-01
Full Text Available Dennis Drotar, Peggy Crawford, Margaret BonnerCincinnati Children’s Hospital Medical Center, Cincinnati, Ohio, USAAbstract: Collaborative or shared decision-making between health care providers and families can facilitate treatment adherence, health outcomes, and satisfaction with care in the management of pediatric chronic illness, but raises special challenges. Barriers such as authoritarian models of medical care as well as absence of time and opportunity for dialogue limit collaborative decision making and can disrupt treatment adherence. However, models of provider-family communication that emphasize communication and shared goal-setting inform an anticipatory guidance model of collaborative decision-making that can enhance treatment adherence. Salient challenges and strategies involved in implementing collaborative decision-making in pediatric chronic illness care are described. Research is needed to: 1 describe the communication and decision-making process in the management of pediatric chronic illness; and 2 evaluate the impact of interventions that enhance collaborative decision-making on provider-family communication, illness management, and treatment adherence.Keywords: collaborative decision-making, shared decision-making, treatment adherence, pediatric chronic illness
