The Effect of Rational and Intuitive Decision-Making Strategies on Interest Appraisals
Career counseling requires clients to make assessments and predictions of their interests, necessitating the use of both rational and intuitive processes. Dual-processing models of human decision-making have not been experimentally explored within the context of vocational assessment. One-hundred thirty-six participants chose among eight occupational/educational videos after an unconscious-intuitive, conscious-rational, or decision-as-usual information processing manipulation. Participant interest was assessed before, during, and 2 weeks following the video in order to determine differences across conditions. The results yielded three conclusions. First, the unconscious-intuitive manipulation resulted in interest forecasts that were more predictive of actual interest than did the conscious-rational manipulation or the decision-as-usual conditions. Second, interest levels were recalled more accurately by participants who made choices under unconscious-intuitive conditions than by those in the other two conditions. Finally, a history of occupational engagement was found to be related to decisional quality but only for the control group. These results are discussed in the context of vocational theory
Modélisation, Commande et Mise en Oeuvre de deux Ponts Triphasés Back-to-Back avec Contrôle des Flux de Puissance et de la Tension du Bus DC : Application à l'émulation de la chaîne de conversion électrique des houlogénérateurs directs
National audienceCet article présente la modélisation, la simulation et la mise en œuvre expérimentale d’un onduleur triphasé back-to-back avec prise en charge de la gestion des flux de puissances (active et réactive) et de la régulation de la tension du bus DC. La stratégie de commande utilisée offre la possibilité de contrôler indépendamment les puissances active et réactive. Les deux boucles de régulation (courant et tension) sont complètement découplées et indépendantes. L’objectif de ce dispositif est d’émuler le fonctionnement de la chaîne de conversion électrique de houlogénérateurs directs (tels que le SEAREV), avec un pont triphasé contrôlant la génératrice et la récupération d’énergie et l’autre pont injectant l’énergie au réseau. La production résultante est fortement pulsante et à très basse fréquence (moins d’un Hertz). Les résultats de simulation sous Maltab/Simulink ainsi que les résultats expérimentaux obtenus en utilisant des modules d’onduleurs pédagogiques pilotés par des cartes DSP sont présentés
Cyclic animation using Partial differential Equations
YesThis work presents an efficient and fast method for achieving cyclic animation using Partial Differential Equations (PDEs). The boundary-value nature associ- ated with elliptic PDEs offers a fast analytic solution technique for setting up a framework for this type of animation. The surface of a given character is thus cre- ated from a set of pre-determined curves, which are used as boundary conditions so that a number of PDEs can be solved. Two different approaches to cyclic ani- mation are presented here. The first consists of using attaching the set of curves to a skeletal system hold- ing the animation for cyclic motions linked to a set mathematical expressions, the second one exploits the spine associated with the analytic solution of the PDE as a driving mechanism to achieve cyclic animation, which is also manipulated mathematically. The first of these approaches is implemented within a framework related to cyclic motions inherent to human-like char- acters, whereas the spine-based approach is focused on modelling the undulatory movement observed in fish when swimming. The proposed method is fast and ac- curate. Additionally, the animation can be either used in the PDE-based surface representation of the model or transferred to the original mesh model by means of
a point to point map. Thus, the user is offered with the choice of using either of these two animation repre- sentations of the same object, the selection depends on the computing resources such as storage and memory capacity associated with each particular application
Formulation and Optimization by Experimental Design of Low-Fat Mayonnaise Based on Soy Lecithin and Whey
The main objective of this study is to develop a new formula for a diet mayonnaise-like sauce without cholesterol. Emulsifying power is provided by the use of soy lecithin and the total fat content was limited to 16%. Droplet size measurement of employed mayonnaise samples at different times show that the largest diameter of fat does not exceed 18.5 µm with a yield stress of 56.1 Pa. Results of stability to centrifugation reveal that the absence of the supernatant oily layer ensures the stability of the emulsion. Using the experimental design method, the number of trials can be limited to a number of 16 experiments, and best formulation of the mayonnaise (without cholesterol) was obtained
The role of leadership in salespeople’s price negotiation behavior
Salespeople assume a key role in defending firms’ price levels in price negotiations with customers. The degree to which salespeople defend prices should critically depend upon their leaders’ influence. However, the influence of leadership on salespeople’s price defense behavior is barely understood, conceptually or empirically. Therefore, building on social learning theory, the authors propose that salespeople might adopt their leaders’ price defense behavior given a transformational leadership style. Furthermore, drawing on the contingency leadership perspective, the authors argue that this adoption fundamentally depends on three variables deduced from the motivation–ability–opportunity (MAO) framework, that is, salespeople’s learning motivation, negotiation efficacy, and perceived customer lenience. Results of a multi-level model using data from 92 salespeople and 264 salesperson–customer interactions confirm these predictions. The first to explore contingencies of salespeople’s adoption of their transformational leaders’ price negotiation behaviors, this study extends marketing theory and provides actionable guidance to practitioners
Good for the Self:Self-Compassion and Other Self-Related Constructs in Relation to Symptoms of Anxiety and Depression in Non-clinical Youths
This study examined relationships among self-compassion, self-esteem, and self-efficacy and symptoms of anxiety disorders and depression in a sample of 132 non-clinical adolescents aged 12-17 years. The results first of all indicated that the Shortened Self-Compassion Scale for Adolescents was reliable (i.e., all Cronbach's alphas were >.70) and valid in terms of both construct (as demonstrated by a principal components analysis which revealed the hypothesized three-factor structure) and concurrent validity (i.e., as shown by means of positive correlations with self-esteem and self-efficacy). Further, the expected negative correlations were found between self-compassion and anxiety and depression, indicating that higher levels of this self-related construct are associated with lower symptom levels, and vice versa. Of the three components of self-compassion, mindfulness appeared most convincingly related to symptoms of anxiety and depression. Finally, when controlling for other self-related constructs, self-compassion no longer accounted for a significant proportion in the variance of symptom levels. In contrast, self-esteem (depression) and in particular self-efficacy (anxiety and depression) did show unique explanatory power
