Behavioral economic demand curves (Hursh, Raslear, Shurtleff, Bauman, & Simmons, 1988) are innovative approaches to characterize the relationships between consumption of a substance and its price. In this article, we investigate common analytical issues in the use of behavioral economic demand curves, which can cause inconsistent interpretations of demand curves, and then we provide methodological suggestions to address those analytical issues.

We first demonstrate that log transformation with different added values for handling zeros changes model parameter estimates dramatically. Second, demand curves are often analyzed using an overparameterized model that results in an inefficient use of the available data and a lack of assessment of the variability among individuals.

To address these issues, we apply a nonlinear mixed effects model based on multivariate error structures that has not been used previously to analyze behavioral economic demand curves in the literature. We also propose analytical formulas for the relevant standard errors of derived values such as P max, O max, and elasticity. The proposed model stabilizes the derived values regardless of using different added increments and provides substantially smaller standard errors. We illustrate the data analysis procedure using data from a relative reinforcement efficacy study of simulated marijuana purchasing.  相似文献

The “evoking freedom” technique is a verbal compliance procedure that solicits someone to comply with a request by simply telling them they are free to accept or to refuse the request. The measure of the efficiency of this technique on compliance with large samples and the evaluation of its influence on various requests was tested in the first set of experiments. This technique was found to be efficient in increasing the number of people who agreed to give money to a requester, the number of smokers who agreed to give a cigarette, passersby who agreed to respond to a survey, and homeowners who agreed to buy pancakes. In the second set of experiments in which the mode of interaction between the requester and the person solicited was tested, the “evoking freedom” technique was found to be associated with greater compliance with a request addressed by mail and through face‐to‐face, phone‐to‐phone, or computer‐mediated interaction. The third set of experiments tested the effect of semantic variations of the “evoking freedom” technique and the weight of the repetition of the semantic evocation of freedom. These later experiments that used various phrases evoking the freedom to comply were found to be associated with greater compliance. Moreover, a double evocation of freedom was associated with even greater compliance than a single evocation. The importance of this technique for commitment communication is discussed.  相似文献

This research focuses on the interrelation of the parent-child attachment, unconventionality, friends' drug use, and the young adult's use of drugs. Data were collected from participants at 4 points in time: early adolescence, late adolescence, early 20s, and late 20s. Data were collected from mothers at the 3 points in time that corresponded with the first 3 collections of data from their children. Both the youths and their mothers were individually interviewed. The findings indicated that the effect of parent-child mutual attachment was mediated through early adolescent personality attributes of greater responsibility, less rebelliousness, and intolerance of deviance. These non-drug-prone personality and behavioral attitudes, in turn, insulated the young adult from affiliating with drug-using peers, and these attitudes were related to less drug use in the early 20s and ultimately in the late 20s. The results suggest that interventions focused on enhancing parent-child mutual attachment should result in a reduction of the risk factors conducive to drug use during the late 20s. The fact that these findings cover a decade and a half, from early adolescence to the late 20s, underscores the significance of placing drug use in a perspective that includes familial and behavioral aspects.  相似文献

The interrelation of childhood aggression, unconventionality, academic orientation, work involvement, and drug use was explored. Data were obtained for the research participants when they were 5 to 10 years old. Follow-up interviews were conducted when the participants were 15 to 20 years old and again at 21 to 26 years old. Latent variable causal analysis was used, and the findings reveal long-term relations between early childhood aggression and adolescent problem behavior in the academic and occupational areas. The findings also indicate that adolescent drug use generates an early involvement with adult role behaviors, such as work at the expense of further education. Implications of the findings for prevention are discussed.  相似文献

Wittgenstein's critical and constructive analysis of ostensive definition is examined. Nine fundamental logico‐metaphysical errors stemming from misapprehension of ostensive definition are identified, most of which occur in the Tractatus. The Fregean holistic conception of meaning is applied to the special case of ostension. Ostensive definition is one rule among others. It is not unequivocal, it does not link language with reality, nor does it determine its own application. The role of samples in ostensive definition of perceptual properties is analysed, and the affinities between samples and Tractarian simples stressed. Samples belong to the method of representation, and not to the substance of reality. The constructive analysis is brought to bear upon the previously identified errors. Finally, a further range of problems concerning ostensive definition is raised.  相似文献

Emerging research has documented greater risk for posttraumatic stress disorder (PTSD) and depression among young adults with prior adverse childhood experiences (ACEs). Building upon prior findings, we hypothesised that religious/spiritual (R/S) struggles may serve as an intervening pathway through which accumulation of ACEs impacts mental health symptom severity in this population. Young adults (N?=?458) were recruited from a southeastern university to complete an online self-report survey that assessed for ACEs, lifetime trauma exposure, R/S struggles, PTSD and depressive symptomatology. Bivariate correlations yielded significant positive relationships between ACEs and all six types of R/S struggles, depression, and PTSD. Additionally, when accounting for non-childhood trauma exposure, the mediational analyses indicated an indirect effect of struggles with ultimate meaning on the well-establish association between ACEs and mental health symptoms. Clinical implications (such as the importance of fostering meaning making), study limitations, and future research directions are discussed.  相似文献

Words that have been learned early in life are responded to faster than words that have been acquired later. Subjective ratings of acquisition ages have been successfully employed to study the effect of age of acquisition (AoA). Although a large number of norms exist in many languages, fewer are available for German. Therefore, subjective AoA ratings for 3,259 German words were collected online, including 2,363 nouns and 473 verbs. These words were presented in lists of 140 words, and participants rated the age in years at which they had first learned each word. A split-half correlation testified to a high internal reliability. There were also high correlations with rated AoA values for subsets of the items that had been collected in previous studies, in both German and English. Age and gender were found to influence the ratings very weakly, in that older and male participants tended to give slightly higher age ratings. Education, multilingualism, and frequent usage of languages other than German did not exert an influence on the rating values. These new ratings will extend the currently existing norms available for language and reading research across languages and will provide researchers with a wider choice of word stimuli. The ratings are available expressed in two measurements: age in years, and AoA rated on a 7-point Likert scale.  相似文献

In this article, we explore the debate on corporate citizenship and the role of business in global governance. In the debate on political corporate social responsibility it is assumed that under globalization business is taking up a greater political role. Apart from economic responsibilities firms assume political responsibilities taking up traditional governmental tasks such as regulation of business and provision of public goods. We contrast this with a subsidiarity-based approach to governance, in which firms are seen as intermediate actors who have political co-responsibilities in society endowed upon them by (inter)national governmental institutions. We argue that both approaches face conceptual and empirical problems, and do not make clear the content and scope of political corporate responsibility. Based on Iris Marion Young’s account of political responsibility we argue that corporate actors and governmental actors have a shared responsibility to tackle societal problems. Taking political corporate responsibility not only entails engaging in private action or engaging in public–private partnerships, but it also includes aiding governmental actors to remedy injustice or even create public institutions where they do not yet exist. By adding this perspective we contribute to the debate on responsibility in corporate citizenship and clarify the political role business can play in global governance.  相似文献
