Selecting a new technology strategy using multiattribute,multilevel decision trees

Research indicates that selecting a strategy to best exploit a new technology is a complex decision-making process. The task involves making a series of decisions with multiple alternatives, each to be evaluated by multiple criteria whose values have high levels of uncertainty. This paper presents a methodology for modelling a new technology decision using decision trees and an optimizing algorithm. A problem of a mining company considering the adoption of new technology is used to illustrate the decision-making task and modelling methodology. A numerical solution to the case demonstrates the potential of the optimizing technique in strategy selection.     

Parenting Sensitivity,Parental Depression and Child Health: The Mediational Role of Parental Self-Efficacy

This paper discusses the theoretical role of parental self-efficacy, or parents' beliefs in their competence and effectiveness in the parental role, as a mediator of relations between parent–child risk and parental sensitivity. Evidence is marshalled from studies of parenting in the contexts of maternal depression and child health risk to support the premise that parent–child characteristics affect parental sensitivity indirectly via their more direct impact on parental feelings of efficacy, and that parenting efficacy represents the ‘final common pathway’ in the prediction of parenting sensitivity. Also considered in this working model are specific social-contextual factors as independent contributors to parenting efficacy and as possible moderators of relations between parent–child characteristics and self-efficacy. Implications for intervention are discussed. © 1996 John Wiley & Sons, Ltd.     

A multi-objective mathematical programming problem with fuzzy relation constraints

In this study we discuss the problem of multi-objective mathematical programming with constraints defined by ‘max-min’ composite fuzzy relation equations. Since the feasible region is normally non-convex, the properties of the efficient points of a non-convex feasible region under multi-objectives are investigated and illustrated by examples. The necessary and sufficient conditions are proposed and proved. To facilitate decisions, a procedure that transforms these efficient points of an interval-valued decision space into a constant-valued decision space is proposed when the level of confidence is given by a decision maker. Then the transformed problem becomes a multi-attribute decision problem that can be evaluated by Yager's method to find the optimal alternative.     

Commentary on Corradi et al.’s (2019) new conception of aesthetic sensitivity: Is the ability conception dead?

Corradi et al. (British Journal of Psychology, 2019) argue that their new conception of visual aesthetic sensitivity (as responsiveness to aesthetic features in one’s preferences) presents several advantages in comparison with the current ability view of aesthetic sensitivity, usually defined as the ability to judge aesthetic stimuli in accordance with standards (The Journal of Psychology, 1964, 57 and 49). Although the measure they propose is interesting and presents advances to the field, we point to important issues. Notably, the authors conveniently base their comparison between the two conceptions on psychometric double standards, discard a century of research on aesthetic sensitivity by focusing on Eysenck’s speculations, and disguise an extension of already existing aesthetic preference tests (e.g., The Journal of Psychology, 1952, 33 and 199; Empirical Studies of the Arts, 2005, 23 and 165) as a redefinition of aesthetic sensitivity. We conclude that both aesthetic preference and aesthetic sensitivity research are legitimate objects of study, that the authors present interesting ideas to further the study of aesthetic preferences, but that their approach is not new and that its proposed renaming only adds confusion to the field.     

The Role of Children's Neurophysiological Functioning in the Links Between Emotion-Parenting Behaviors and Child Anxiety Symptoms: A Biological Sensitivity to Context Framework

A plethora of data supports links between parenting behaviors and child anxiety, but few studies have examined factors that can contribute to variability in these relations. Adopting a biological sensitivity to context framework, this study explored the role of children's physiological stress reactivity in the links between emotion-parenting and child anxiety symptoms in a group of Chinese families. Sixty-one parent–child dyads (child M_age = 8.21 years, SD = 1.40, range = 6–12 years) participated in an acute stress protocol, from which children's physiological (cortisol and respiratory sinus arrhythmia) responses to a social speech task were recorded. Participants then completed questionnaires assessing parents’ emotion-parenting behaviors and children's anxiety symptoms. Results showed that the relation between supportive emotion-parenting and child anxiety was stronger in the context of greater child RSA suppression to acute stress, such that children higher in RSA suppression exhibited lower anxiety symptoms when supportive emotion-parenting was higher than when it was lower. Thus, these findings supported the biological sensitivity to context model. No significant moderation effect was detected for cortisol reactivity or recovery. Instead, exploratory mediation analyses showed that supportive emotion-parenting was negatively related to child anxiety via greater cortisol recovery. There was also a significant indirect path where unsupportive emotion-parenting was related to blunted cortisol recovery, which in turn was associated with higher child anxiety. The results highlight the importance of coaching parents to respond in supportive ways to children's emotional expressions, particularly in the context of greater child reactivity, to help buffer against childhood anxiety symptoms.     

群体认同对群际敏感效应及其行为表现的影响

通过实验研究了群际互动中个体对不同来源身份的消极群体评价的情绪反应及群体认同的调节作用, 并从情绪-行为反应的连续性视角探索群际敏感效应的行为表现及内在机制。结果发现:(1)相比内群体的消极群体评价, 外群体的消极群体评价更能引起消极情绪反应; (2)群体认同对群际敏感效应起调节作用, 高群体认同者对来自外群体消极评价的情绪反应更加负面, 而低群体认同者这种趋势并不明显; (3)高群体认同者在经历外群体的消极群体评价后会表现出更多的内群体积极行为, 且消极情绪反应对此起中介作用。研究扩展了群际敏感效应的适用范围, 并为探讨其内部机制和后续影响提供了新的研究思路。     

Aging drivers and post delineated express lanes: Threading the needle at 70 miles per hour

Post-delineated express lanes represent a combination of driving complexities that are particularly difficult for older drivers to navigate. The narrow geometry and high speeds that are common to this treatment reflect a critical test for drivers whose depth perception, contrast sensitivity, and visual processing speed are reduced. The present study was designed to empirically examine the effects of age and color of express lane delineators on driver behavior. Three groups of participants (aged 18–39, 40–64, and 65 + years old) were required to complete a series of simulated driving scenarios consisting of combinations of single and dual lane configurations, with speed and lane position measured at the beginning and midpoint of each express lane. All drivers were pre-screened on various visual functioning abilities. Drivers in the 65 and older group show significant age-related declines in depth perception, contrast sensitivity, and phoria which were subsequently correlated with a wide range of driving measures including deceleration rate, brake time, jerk, speed, and lane position. Age related perceptual declines were statistically correlated with slower driving speed and wider lane deviations, including a statistically significant increase in the number of excursions beyond the typical 12-foot lane width. Based on these findings, the behavior of senior drivers was identified as a distinct design condition that should govern the design of high-speed, narrow geometric conditions. This age group requires wider lane widths, particularly at the beginning of single-lane post delimited sections, wider buffer areas around the post markers, and dual lane configurations wherever possible.     

The medial amygdala: Serotonergic inhibition of shock-lnduced aggression and pain sensitivity in rats

Two aspects of the amygdaloid complex (corticomedial and basolateral) were examined with reference to serotonergic inhibition of shock-induced aggression. Fighting was significantly depressed by serotonergic stimulation (5-HT, 10 μg bilateral) in the corticomedial amygdala while serotonergic blockade (methysergide, 5 μg bilateral) in this region increased levels of fighting. No consistent effects were obtained with serotonergic manipulation of the basolateral amygdala. Further investigation revealed that the state of serotonergic activity in medial amygdaloid sites was associated with concomitant alterations in the animals' sensitivity to footshock. Results are discussed in relation to a) a general inhibitory role of serotonin in behavioural mechanisms and b) a dopaminergic-serotonergic balance for behavioural arousal involving medial amygdaloid nuclei.     

Effects of methylphenidate on sensitivity to reinforcement in children diagnosed with attention deficit hyperactivity disorder: an application of the matching law

The behavior of children diagnosed with attention deficit hyperactivity disorder (ADHD) has been hypothesized to be the result of decreased sensitivity to consequences compared to typical children. The present study examined sensitivity to reinforcement in 2 boys diagnosed with ADHD using the matching law to provide more precise and quantitative measurement of this construct. This experiment also evaluated the effects of methylphenidate (MPH) on sensitivity to reinforcement of children with ADHD. Subjects completed math problems to earn tokens under four different variable-interval (VI) schedules of reinforcement presented in random order under both medicated and nonmedicated conditions. Results showed that, in the medicated condition, the matching functions for both subjects resulted in higher asymptotic values, indicating an overall elevation of behavior rate under these conditions. The variance accounted for by the matching law was also higher under the medicated conditions, suggesting that their behavior more closely tracked the changing rates of reinforcement while taking MPH compared to placebo. Under medicated conditions, the reinforcing efficacy of response-contingent tokens decreased. Results are discussed with respect to quantifying behavioral changes and the extent to which the drug interacts with prevailing contingencies (i.e., schedule values) to influence behavioral variability.
