Background: The availability and use of health apps continues to increase, revolutionizing the way mobile health interventions are delivered. Apps are increasingly used to prevent disease, improve well-being, and promote healthy behavior. On a similar rise is the incidence of skin cancers. Much of the underlying risk can be prevented through behavior change and adequate sun protection. Self-monitoring apps have the potential to facilitate prevention by measuring risk (eg, sun intensity) and encouraging protective behavior (eg, seeking shade). Objective: Our aim was to assess health care consumer preferences for sun protection with a self-monitoring app that tracks the duration and intensity of sun exposure and provides feedback on when and how to protect the skin. Methods: We conducted an unlabeled discrete choice experiment with 8 unique choice tasks, in which participants chose among 2 app alternatives, consisting of 5 preidentified 2-level attributes (self-monitoring method, privacy control, data
Background: Digital technological development in the last 20 years has led to significant growth in digital collection, use, and sharing of health data. To maintain public trust in the digital society and to enable acceptable policy-making in the future, it is important to investigate peoples preferences for sharing digital health data. Objective: The aim of this study is to elicit the preferences of the public in different Northern European countries (the United Kingdom, Norway, Iceland, and Sweden) for sharing health information in different contexts. Methods: Respondents in this discrete choice experiment completed several choice tasks, in which they were asked if data sharing in the described hypothetical situation was acceptable to them. Latent class logistic regression models were used to determine attribute-level estimates and heterogeneity in preferences. We calculated the relative importance of the attributes and the predicted acceptability for different contexts in which the data were shared

AU - Coast, J. PY - 2010/6. Y1 - 2010/6. N2 - Aim Maturity-onset diabetes of the young is a monogenic form of familial, young-onset diabetes. It is rare (∼1% diabetes) and may be misdiagnosed as Type 1 diabetes and inappropriately treated with insulin. Type 1 diabetes is characterized by the presence of islet autoantibodies, including glutamate decarboxylase (GAD) and islet antigen-2 (IA-2) antibodies. The prevalence of islet autoantibodies is unknown in maturity-onset diabetes of the young and may have the potential to differentiate this form of diabetes from Type 1 diabetes. The aim of this study was to determine the prevalence of GAD and IA-2 antibodies in patients with maturity-onset diabetes of the young and Type 1 diabetes. Methods We measured plasma GAD and IA-2 antibodies in 508 patients with the most ...
An as-needed combination preventer and reliever regimen was recently introduced as an alternative to conventional daily preventer treatment for mild asthma. In a subgroup analysis of the PRACTICAL study, a pragmatic randomised controlled trial of budesonide-formoterol reliever therapy versus maintenance budesonide plus terbutaline reliever therapy in adults with mild asthma, we recently reported that about two-thirds preferred as-needed combination preventer and reliever therapy. The aim of this study was to determine the relative importance of attributes associated with these two asthma therapies in this subgroup of participants who indicated their preferred treatment in the PRACTICAL study.At their final study visit, a subgroup of participants indicated their preferred treatment and completed a discrete choice experiment using the Potentially All Pairwise RanKings of all possible Alternatives method and 1000minds software.

Abstract: In this paper we derive locally optimal designs for discrete choice experiments. As in Kanninen (2002) we consider a multinomial logistic model, which contains various ualitative attributes as well as a quantitative one, which may range over a sufficiently large region. The derived optimal designs improve upon those given in the literature, but have the feature that every choice set contains alternatives, which coincide in all but the quantitative attributes. The multinomial logistic model may then lead to an unrealistic response behavior, if the quantitative attribute is described by a price variable.. Keywords: conjoint analysis, discrete choice experiment, multinomial logistic model, locally optimal design. ...

Universal coverage campaigns for long-lasting insecticide-treated nets do not always reach the goal of one net for every two household members, and even when ownership of at least one net per household is high, many households may not own enough nets. The retail market provides these households options for replacing or increasing the number of nets they own with products that best fit their needs since a variety of net shapes, sizes, and colours are available. Hence, it is important to understand the factors affecting private net demand. This study explores private demand for nets in Tanzania using a discrete choice experiment. The experiment provides participants the option to buy nets with their own money, and thus should prove more accurate than a hypothetical survey of net preferences. Nearly 800 participants sampled in two regions showed an overall strong demand for nets, with 40% choosing to buy a net across all seven combinations of net prices and characteristics such as size, shape, and

The study of perceptual decisions has been developed as a substitute for investigating more complex multiple attribute decisions. However, little attention has been paid to the similarity of results between the two literatures. Four separate behavioral experiments and a secondary trial- by-trial analysis investigated the sensitivity of perceptual decisions. Results were compared to both previous perceptual decision research and that of multiple attribute decisions in an effort to bridge the divide. The first experiment examined the effect of increasing the similarity of available response alternatives on accuracy and reaction time. The results suggest that high levels of similarity can begin to degrade the decision process by lowering accuracy and slowing reaction time; however these changes may be dependent on the extent to which the alternatives use overlapping neuronal pools. The second experiment examined the effect of increasing the number of response alternatives available for a single ...

Decision-making is a hallmark of higher-order cognitive processing. The neural substrates of decision-making have been studied extensively in the monkey oculomotor system. It has been found that neurons in the oculomotor system modulate their activity by the variable on which animals base their decision, and also appear to encode the dynamics of the decision process. An outstanding question raised by this work is whether the decision-related findings in the oculomotor system generalize to other systems beyond the oculomotor system. This question is of critical importance to decision sciences as decision-related neural signals serve to construct and constraint models of choice behavior. However, the work on the neural basis of decision-making in the monkey oculomotor system cannot address this question because in this literature animals make choices using eye movements. In these tasks, the decision-related neuronal modulation could therefore specifically reflect the decision to make an eye movement, and

Based on examination of variation of practice patterns in the Dartmouth Atlas, John Wennberg, M.D. has suggested three general approaches to reduce inappropriate variation and increase the equity of medical care: increase the amount of effective care, reduce supply sensitive care and increase preference sensitive care [32]. The underuse of DMARDs by patients with RA, is an example of underutilization of effective care. This may be explained by healthcare system failures, individual physician behavior, or in some cases subsets of patients who are informed but elect not to take medications recommended in national standards of care. A recent computer based, simulated decision, discrete choice experiment of 144 RA patients preferences of specific risks and benefits of treatment found that when compared to white adults with RA, African American RA patients were more likely to be classified as risk averse (OR 8.4 [3.1-23.1]) [33]. In general, it is unknown if risk aversion is an inherent culturally ...
What do patients want? Llewellyn5 and Miners6 report linked studies exploring patient preferences for STI services in the UK, in the context of increased provision of such services in primary care over the past decade. Llewellyn et al report that while many participants were willing to test within general practice, perceived lack of expertise was a barrier as was the apparently limited range of tests in general practise. A discrete choice experiment presented by Miners again emphasised patients preference for staff with specialist knowledge, and for the availability of testing for all infections. These are important messages for policymakers.. Patient views are also explored a study by Conway et al,7 who describe quality of life valuations for HPV associated cancer health states.

The participants will be interviewed in a face-to-face setting using computer-assisted personal interviewing technique. We will be using EuroQol Groups Valuation Technology (EQ-VT) software generated by the EuroQol Group. Each respondent will be asked to complete sociodemographic details and self-reported health questionnaire using EQ-5D-5L and the EuroQol Visual Analogue Scale (EQ-VAS). TTO valuation will be done using 10 composite TTO (c-TTO) tasks and 7 discrete choice experiment (DCE) tasks.. In the standard design of c-TTO, there will be 10 blocks of health states. Each block will contain 10 health states which include one anchor state (55555). The blocks used for interview will be randomly selected by the EQ-VT software. In TTO valuation, the respondent is asked to indicate the amount of time he/she is willing to give up to attain perfect health. The respondent will be asked to imagine two alternative health states (life A and life B) described on screen and express the preference using ...
Downloadable (with restrictions)! Increasingly, health economists are required to work across sectors when evaluating options for improving health, health care and well-being. Social care is a key sector which is both influenced by and influences the use and outcomes of health services. This paper reports on a developing approach to measuring social care outcome, designed to reflect outcomes across client groups. In this process it is important that we reflect the relative importance or value of these domains of outcome. This paper reports on a pilot study that investigated the feasibility of using discrete choice experiments to identify a financial willingness to accept valuation of a large number of domains and investigated factors associated with variations in respondents preferences. We conclude that, while the domains themselves need further work, the approach provides a helpful starting point in the difficult issue of reflecting population preferences for a large number of social care outcome
There are two salient facts about health care in low and middle-income countries; 1) the private sector plays an important role and 2) the care provided is often of poor quality. Despite these facts we know little about what drives quality of care in the private sector and why patients continue to seek care from poor quality providers. We use two field studies in India that provide unique insight into this issue. First, we use a discrete choice experiment to show that patients are willing to pay higher prices for better technical quality (defined by correct treatment and correct diagnosis). Second, we use standardized patients to show that private providers who provide better technical quality are not able to charge higher prices. Instead providers are able to charge higher prices for elements of quality that the patient can observe (good patient interactions and more effort), which are less important for health outcomes. Taken together, this research highlights a market inefficiency and ...

Usually only KEY1= is needed for an MCQ scoring key.. Up to 99 keys can be provided for scoring the response choices, with control variables KEY1= through KEY99=. Usually KEY1= is a character string of correct response choices. The standard is one column per correct response, or two columns if XWIDE=2.. As standard, responses matching the characters in KEY1= are scored 1. Other valid responses are scored 0. KEY2= through KEY99= are character strings of successively more correct response choices to be used when more than one level of correct response choice is possible for one or more items. The standard score value for KEY2= is 2, and so on up to the standard score value for KEY99= which is 99. The values assigned to these keys can be changed by means of KEYSCR=. If XWIDE=1, only the values assigned to KEY1= through KEY9= can be changed, KEY10= through KEY99= retain their standard values of 10 through 99. If XWIDE=2, the all KEYn= values can be changed.. More complicated scoring can be done ...

Some of the highly controversial questions in macroeconomics critically hinge on the value of a single parameter of consumer preference--the elasticity of intertemporal substitution. This paper provides new estimates of this parameter for individual G-7 and a panel of twenty OECD countries. We find that single equation GMM estimates are typically small and imprecise, consistent with Halls (1988) finding from the U.S. data. Estimation of a system of equations that takes into account the cross-equation restrictions implied by theory, however, generally gives larger and better determined values for the parameter. The panel procedure also yields relatively large estimates. Overall our multi-country results contradict the hypothesis of zero intertemporal substitution.
A dynamic risk-sensitive portfolio optimization problem under risk constraints is discussed by the use of coherent risk measures and fuzzy random variables
The neural mechanisms underlying the selection and initiation of voluntary actions in the absence of external instructions are poorly understood. These mechanisms are usually investigated using a paradigm where different movement choices are self-generated by a participant on each trial. These free choices are compared with instructed choices, in which a stimulus informs subjects which action to make on each trial. Here, we introduce a novel paradigm to investigate these modes of action selection, by measuring brain processes evoked by an instruction to either reverse or maintain free and instructed choices in the period before a go signal. An unpredictable instruction to change a response plan had different effects on free and instructed choices. In instructed trials, change cues evoked a larger P300 than no-change cues, leading to a significant interaction of choice and change condition. Free-choice trials displayed a trend toward the opposite pattern. These results suggest a difference between
Prolonged waiting times for elective treatment have long been considered a serious problem of the Norwegian health care system. Overall waiting times have, due to both supply and demand reforms, dropped significantly over recent years. Despite the positive development, many patients still face substantial waiting times. The analysis provides support for claiming that a policy of combining patient choice of hospital with the removal of geographical restrictions on referrals may contribute to the reduction in waiting times for individual elective patients. The main results of the empirical analyses were found to be robust over different statistical model specifications. Patients who chose to move hospitals benefit the most. They spend about 11 weeks less, on average, waiting for hospital treatment than those who neither chose nor moved. The results corroborate with the results of a few previous empirical analyses, like The London Patient Choice Project. There, a reduction in waiting times for all ...
This article reexamines evidence that some 5O% of disposable income goes to households who simply consume their current incomes. Previous studies of such rule-of-thumb behavior have typically used log-linear Euler equations and have not distinguished between intertemporal substitution and relative risk aversion. In contrast, I use generalized method of moments to estimate the importance of rule-of-thumb behavior and separate intertemporal substitution from risk aversion by using the Epstein-Zin utility function. Using postwar U.S. data, I cannot reject the hypothesis that all income goes to permanent-income households--that is, that there are no rule-of-thumb households.
One of these is precisely what explained binary choices are. Binary alternate options bring a very high amount of hazards when it comes to predicting the expense of a house at a supplied element in time. Binary alternate options are merely two in general: the money-or-nothing choice as well as the tool-or-absolutely nothing choice. The entire year 2008 was actually a modifying aspect in the background of repaired profit possibilities. Undoubtedly from that time binary selections online-web sites showed up as well as auctioned directly into step up change-dealt all-or-absolutely nothing choices. This development was quick since it was within the mindset from the Securities and also Exchange Commission (SEC)s selection to allow the list of income-or-practically nothing set up comes back selections. This was a result of the proposal in the Options Eradicating Business in 2007 to include binary choices in its regulations..

Gerber, Eberhart and Andrea entered a small, dark room in which a row of chairs faced a large one-way glass which made up most of the rooms far wall. On the other side of this glass was a much larger room, a well-lit chamber containing a variety of high-tech apparatus and controls, most of which Andrea could not identify. Without a word, she and the two men sat down. They all knew what this place was for; there was no need for discussion. Andrea recognized Nina immediately. She had been restrained on a five foot wide, eight foot long metal table that was surrounded by the strange array of equipment. The top of the table had been tilted up forty-five degrees, leaving Nina neither lying flat nor standing, but positioned so as to give the three observers an optimal view of the proceedings. Ninas body lay spread-eagle and face up, her limbs pulled wide apart and stretched to their limits. Manacles welded to the table secured her wrists and ankles, completely immobilizing her. Nina was naked of ...
Probability and statistics are not dependent on an individuals choice. Its dependent on the population. The population in this case would be the cars that drive on that stretch of highway. This determines the probability of getting into an accident. So an individuals can choose whether to drive on the highway or do things like wear a seat belt or drive at a certain speed. The probability of an accident occurring isnt the function of individual choice but of the population or the event thats occurring. This illustrates free will beautifully which reaches down to Planck scales. So probability isnt interfered with because its a function of the population. If 50% of the cars stopped driving on that highway that wouldnt interfere with probability that would just change the statistics because theres a decrease in the population for the event ...

Consistent with the results of the Bechara study, our subjects gradually concentrated their choices on deck B (Fig. 2). The beginning phase of the task was an exploratory period in which both populations sampled each deck equally. For the next 20 draws subjects shifted towards deck B drawing on average 8 of the 20 cards from deck A. In the final 10 draws both groups largely abandoned deck A: on average the younger subjects chose deck A two times of 10 and the older subjects chose deck A three times of 10. In summary both populations appear to have adapted the same way to the payoffs.... ...

There also exist problems with the studys design (given the conclusions of the media). Since participants were automatically supplied with drugs on sample days, we cannot make any solid deductions about whether the same results would be garnered in periods of abstinence. Also, given that many of the participants may have been occasional users, a hit of meth every few days may have been ample, meaning the only real option to go for would have been money anyway. This also means that the employed strategy of many may have been to sequester funds for purchase of drugs after the experiment was over. However, this is unlikely to have been the case - at least if the plan was to spend the monetary rewards on meth. The values of the drug and monetary rewards over the course of the study were well matched ($60-$80 and $100, respectively), and given the average dose of meth (250mg) will set you back around $80 on the streets of New York (the studys location), the participants would receive the same ...

This was also shown to be the case for the multinomial logit model. Thus, for the conditional and multinomial logit models, the ratio of probabilities of any two alternatives is necessarily the same regardless of what other alternatives are in the choice set or what the characteristics of the other alternatives are. This is referred to as the IIA property. The IIA property is useful from the point of view of estimation and forecasting. For example, it allows the prediction of demand for currently unavailable alternatives. If the IIA property is appropriate for the choice situation being considered, then estimation can be based on the set of currently available alternatives and then the estimated model can be used to calculate the probability that an individual would choose a new alternative not considered in the estimation procedure. However, the IIA property is restrictive from the point of view of choice behavior. Models that display the IIA property predict that a change in the attributes of ...

Background/Rationale: It is important that individuals with serious mental illness have access to treatments that meet their preferences, and that they make informed choices among alternative treatments. Too often, preferences are not being routinely elicited, nor used to guide which treatments are made available. Schizophrenia is a serious mental illness that is common and produces substantial disability when poorly treated. National treatment guidelines specify that individuals with schizophrenia should receive evidence-based treatments that improve outcomes. For example, obesity is a pressing problem in this population, a side-effect of commonly used medications, and a cause of cardiovascular disease and premature mortality. There are multiple, different psychosocial interventions for weight management that can lead to reduced weight. None are widely used. If individuals preferences were routinely assessed, then clinicians and managers would know when to make alternative treatments ...

This bibliography includes abstracts of 59 studies and review articles which are related to the effect of color coding on choice reaction time. As color displays become more widely used for information gathering and decision-making tasks, the effect of color coding on these tasks and their components will become increasingly important design considerations. Choice reaction time, the time required to make a binary choice, affects the total execution time of many decision-making and information gathering tasks, and seems to be a particularly relevant measure of effectiveness of color coding. This bibliography draws together much of the current literature, for reference by human factors researchers and systems designers. Two techniques lend themselves to measurement of choice reaction time the Sternberg paradigm and the Within-Task Subtractive Method.

N2 - Acetaldehyde, the first alcohol metabolite, is responsible for many pharmacological effects that are not clearly distinguishable from those exerted by its parent compound. It alters motor performance, induces reinforced learning and motivated behavior, and produces different reactions according to the route of administration and the relative accumulation in the brain or in the periphery. The effective activity of oral acetaldehyde represents an unresolved field of inquiry that deserves further investigation. Thus, this study explores the acquisition and maintenance of acetaldehyde drinking behavior in adult ...
Background: Exercise is effective in improving non-specific low back pain (LBP). Certain components of physical exercise, such as the type, intensity and frequency of exercise, are likely to influence participation among working adults with non-specific LBP, but the value and relative importance of these components remain unknown. The studys aim was to examine such specific components and their influence on individual preferences for exercise for secondary prevention of non-specific LBP among working adults. Methods: In a discrete choice experiment, working individuals with non-specific LBP answered a webbased questionnaire. Each respondent was given ten pairs of hypothetical exercise programs and asked to choose one option from each pair. The choices comprised six attributes of exercise (i.e., type of training, design, intensity, frequency, proximity and incentives), each with either three or four levels.

Certain components of physical exercise, such as the type, intensity and frequency of exercise, are likely to influence participation among working adults with non-specific LBP, but the value and relative importance of these components remain unknown. The studys aim was to examine such specific components and their influence on individual preferences for exercise for secondary prevention of non-specific LBP among working adults. Methods: In a discrete choice experiment, working individuals with non-specific LBP answered a webbased questionnaire. Each respondent was given ten pairs of hypothetical exercise programs and asked to choose one option from each pair. The choices comprised six attributes of exercise (i.e., type of training, design, intensity, frequency, proximity and incentives), each with either three or four levels. A conditional logit regression that reflected the random utility model was used to ...
Methods In a discrete choice experiment, participants evaluated eight choice sets, each of which showed two cigarette packages from four different brands and tar levels (high vs low), accompanied by an insert that included between-subject manipulations (ie, listing of HPHCs vs grouping by disease outcome and numeric values ascribed to HPHCs vs no numbers) and within-subject manipulations (ie, 1 of 4 warning topics; statement linking an HPHC with disease vs statement with no HPHC link). For each choice set, participants were asked: (1) which package is more harmful and (2) which motivates them to not smoke; each with a no difference option. Alternative-specific logit models regressed choice on attribute levels. ...
Successful choice under risk requires the integration of information about outcome probabilities and values and implicates a brain network including the ventromedial prefrontal cortex (vmPFC) and posterior parietal cortex (pPAR). Damage to the vmPFC is linked to poor decision-making and increased risk-taking. Electrophysiological and neuroimaging data implicate the pPAR in the processing of reward probability during choice, but the causal contribution of this area has not been established. We compared patients with lesions to the pPAR (n = 13), vmPFC (n = 13), and healthy volunteers (n = 22) on the Roulette Betting Task, a measure of risk-sensitive decision-making. Both lesion groups were impaired in adjusting their bets to the probability of winning. This impairment was correlated with the extent of pPAR, but not vmPFC, damage. In addition, the vmPFC group chose higher bets than healthy controls overall, an effect that correlated with lesion volume in the medial orbitofrontal cortex. Both lesion groups

Results Questionnaire response rate was 49% (1343 of 2740). Women, younger people, the less well-educated and those with higher income had a more positive attitude towards the PN. Older people had a more positive attitude to the doctor. Results from the DCE indicated that whilst most respondents would ...
The 3-day Outcomes Workshop includes material linked directly to the needs of organisations, such as the National Institute for Health and Care Excellence (NICE), which make decisions about health care delivery and funding. The workshop covers the key principles of outcomes measurement and valuation as well as their practical implementation in health technology assessment. It focusses on the design, construction and application of a range of approaches to measuring and valuing health outcomes. The approaches considered include methods used in healthcare economic evaluation, such as quality-adjusted life years (QALYs) based on preference-based generic measures (e.g. EQ-5D, HUI); approaches used to map from clinical and disease-specific outcomes to generic measures; and direct elicitation of preferences. The use of discrete choice experiments is also considered. This workshop assumes participants have a basic familiarity with health technology assessment (HTA) and focuses on the role and ...

PURPOSE: To establish the relative weighting given by patients and healthcare professionals to gains in diagnostic sensitivity versus loss of specificity when using CT colonography (CTC) for colorectal cancer screening. MATERIALS AND METHODS: Following ethical approval and informed consent, 75 patients and 50 healthcare professionals undertook a discrete choice experiment in which they chose between standard CTC and enhanced CTC that raised diagnostic sensitivity 10% for either cancer or polyps in exchange for varying levels of specificity. We established the relative increase in false-positive diagnoses participants traded for an increase in true-positive diagnoses. RESULTS: Data from 122 participants were analysed. There were 30 (25%) non-traders for the cancer scenario and 20 (16%) for the polyp scenario. For cancer, the 10% gain in sensitivity was traded up to a median 45% (IQR 25 to |85) drop in specificity, equating to 2250 (IQR 1250 to |4250) additional false-positives per additional true
In this paper we present a stochastic route choice model for transit networks that explicitly addresses route correlation due to overlapping alternatives. The model is based on a multi-objective mathematical programming problem, the optimality conditions of which generate an extension to the Multinomial Logit models. The proposed model considers a fixed point problem for treating correlations between routes, which can be solved iteratively. We estimated the new model on the Santiago (Chile) Metro network and compared the results with other route choice models that can be found in the literature. The new model has better explanatory and predictive power that many other alternative models, correctly capturing the correlation factor. Our methodology can be extended to private transport networks.
To date there have been no value sets to support the use of the EQ-5D-Y in cost-utility analysis. Discrete choice experiments (DCEs) can be used to obtain values on a latent scale, but these values require anchoring at 0 = dead to meet the conventions of quality-adjusted life year (QALY) estimation. This Research Paper describes a study in which four stated preference methods for anchoring EQ-5D-Y values were compared: visual analogue scale, DCE (with a duration attribute), lag-time TTO and the recently developed location-of-dead (LOD) element of the personal utility function approach. ...

A study conducted by researchers based at the St. Jude Childrens Research Hospital has determined that healthy lifestyle choices can help cancer survivors avoid the metabolic syndrome.
Behavior becomes difficult to analyze when there are many stimuli and many response options. As a consequence, in most laboratory experiments the numbers of stimuli and choices are limited, with the two-alternative forced-choice experiment the most widely adopted. This minimal approach has been successful in studying reinforcement learning, in which responses to rewarded stimuli lead to predictable changes in behavior (1). To what extent can the basic principles of reinforcement learning, coupled with a complex environment and a large memory, account for more complex behaviors? The leaders of the cognitive revolution in the 1950s assumed that reinforcement learning could not account for cognitive behaviors such as language and reasoning, but surprisingly, recent advances in computational theory and experimental studies have challenged this assumption. A tour de force study in PNAS (2) adds to this evidence by showing that reinforcement learning can explain not only behavioral choice in a complex ...
The UK Black and The Health Divide reports considered two primary mechanisms for understanding how social determinants influence health: cultural/behavioral and materialist/structuralist[17] The cultural/behavioral explanation is that individuals behavioral choices (e.g., tobacco and alcohol use, diet, physical activity, etc.) were responsible for their development and deaths from a variety of diseases. However, both the Black and Health Divide reports found that behavioral choices are determined by ones material conditions of life, and these behavioral risk factors account for a relatively small proportion of variation in the incidence and death from various diseases. The materialist/structuralist explanation emphasizes the peoples material living conditions. These conditions include availability of resources to access the amenities of life, working conditions, and quality of available food and housing among others. Within this view, three frameworks have been developed to explain how social ...

Waiting times for elective care have been considered a serious problem in many health care systems. A topic of particular concern has been how administrative boundaries act as barriers to efficient patient flows. In Norway, a policy combining patients choice of hospital and removal of restriction on referrals was introduced in 2001, thereby creating a nationwide competitive referral system for elective hospital treatment. The article aims to analyse if patient choice and an increased opportunity for geographical mobility has reduced waiting times for individual elective patients. A survey conducted among Norwegian somatic patients in 2004 gave information about whether the choice of hospital was made by the individual patient or by others. Survey data was then merged with administrative data on which hospital that actually performed the treatment. The administrative data also gave individual waiting time for hospital admission. Demographics, socio-economic position, and medical need were controlled for
The RPL can take on a number of different functional forms and incorporate a number of underlying distribution assumptions. The most popular assumptions are normal, triangular, uniform and log-normal distributions (Bhat, 2000; 2001). The log-normal distribution is applied if the response parameter needs to be a specific sign (Louviere et al., 2000; Carlsson et al., 2003). Where dummy variables are used, a uniform distribution with a (0, 1) bound is appropriate. It can be difficult to determine which variables to distribute and which distributions to choose. Some applications only randomise the cost variable, others choose to randomise all non-price variables and leave cost as non-random (Layton, 2000; Anderson, 2003). The latter choice is favoured for two reasons: firstly, the distribution of the marginal willingness to pay (WTP) for an attribute is simply the distribution of that attributes parameter estimate, and, secondly, it allows the cost variable to be restricted to be non-positive for ...

Perceptual decisions occur after the evaluation and integration of momentary sensory inputs, and dividing attention between spatially disparate sources of information impairs decision performance. However, it remains unknown whether dividing attention degrades the precision of sensory signals, precludes their conversion into decision signals, or dampens the integration of decision information toward an appropriate response. Here we recorded human electroencephalographic (EEG) activity while participants categorized one of two simultaneous and independent streams of visual gratings according to their average tilt. By analyzing trial-by-trial correlations between EEG activity and the information offered by each sample, we obtained converging behavioral and neural evidence that dividing attention between left and right visual fields does not dampen the encoding of sensory or decision information. Under divided attention, momentary decision information from both visual streams was encoded in slow parietal
How do we make decisions? Conventional decision theory tells us only which behavioral choices we ought to make if we follow certain axioms. In real life, however, our choices are governed by cognitive mechanisms shaped over evolutionary time through the process of natural selection. Evolution has created strong biases in how and when we process information, and it is these evolved cognitive building blocks-from signal detection and memory to individual and social learning-that provide the foundation for our choices ...
The integration of stimuli from the same or different modalities offers many benefits such as enhanced discrimination and accelerated reaction to objects. This thesis investigates the effects of stimulis spatial location on the redundancy gain (RG) obtained with cross-modal and within-modal stimulations. The RG is a decrease in reaction times (RT) when two or more stimuli are presented simultaneously rather than a single stimulation. The first study investigated cross-modal visuo-tactile integration in a single reaction time task and a choice reaction time task. Each unisensory stimulus was presented to either the left or right hemispace, and multisensory stimuli were presented in a unilateral (e.g. visual right/tactile right) or bilateral configuration (e.g. visual right/tactile left). The first task was a simple reaction time (SRT) paradigm where participants had to responded to all stimulations, irrespective of spatial position. Results showed that multisensory gain and coactivation were the ...

Anatomical, neuroimaging and lesion studies indicate that prefrontal cortex (PFC) can be subdivided into different subregions supporting distinct aspects of decision making. However, explanations of neuronal computations within these subregions varies widely across studies. An integrated and mechanistic account of PFC function therefore remains elusive. Resolving these debates demands a rich dataset that directly contrasts neuronal activity across multiple PFC subregions within a single paradigm, whilst experimentally controlling factors such as the order, duration and frequency in which choice options are attended and compared. Here, we contrast neuronal population responses between macaque orbitofrontal (OFC), anterior cingulate (ACC) and dorsolateral prefrontal cortices (DLPFC) during sequential value-guided information search and choice. From the first fixation of choice-related stimuli, a strong triple dissociation of information encoding emerges in parallel across these PFC subregions. As further

This study examined performance measures and eye movements associated with complex arithmetic strategies in young and older adults. Participants added pairs of three-digit numbers using two different strategies, under choice and no-choice conditions. Older adults made more errors but were not significantly slower than young adults, and response times and errors showed no interaction between age and the number of carries. Older adults chose strategies less adaptively than young adults. Eye movements were consistent with use of required strategies on no-choice trials and reported strategies on choice trials. Eye movement data also suggested that young adults more successfully distinguished between strategies. Implications of these findings for understanding aging effects in complex arithmetic are discussed ...

Development in risk-taking tendencies and impulsive control have been attributed to an imbalance between subcortical and cortical brain regions (Somerville et al., 2010; Casey, 2015), but very few studies have examined the anatomical connections between these areas in relation to impulsive choice. One important dimension of impulsivity is the ability to delay gratification (Whelan et al., 2012). Next to examining developmental patterns in impulsive choice and frontostriatal WM integrity, the current study aimed to test whether the integrity of frontostriatal WM connections mediated and predicted the ability to delay gratification across development. We were able to demonstrate that age-related increases in the preference for delayed rewards (i.e., less impulsive choice) were significantly dependent on a better quality of connections between the PFC and striatum. Moreover, the longitudinal analysis revealed that stronger connectivity between striatum and PFC predicted less impulsive choices 2 ...
