Passion and gambling: on the validation of the Gambling Passion Scale (GPS)

Vallerand and his colleagues (Vallerand & Blanchard, 1999; Vallerand, Blanchard, Koestner, & Gagné, 2001) have recently proposed a new concept of passion. According to these authors, passion refers to a strong inclination toward an activity that we like, find important, and in which we invest time. Vallerand et al. have identified two types of passion: obsessive and harmonious. Obsessive passion refers to an internal pressure that forces an individual to engage in the activity. Harmonious passion, on the other hand, refers to an internal force that leads an individual to choose freely to engage in an activity. While obsessive passion has been shown in some circumstances to lead to negative psychological and physical consequences, harmonious passion generally leads to positive psychological and physical consequences. The purpose of the present research was to validate a measure of passion toward gambling: the Gambling Passion Scale (GPS). The GPS consists of two subscales (obsessive passion and harmonious passion) comprising five items each. Results from two studies involving a total of 340 participants revealed satisfactory internal consistency and temporal stability indices, as well as a two-factor structure supported by exploratory and confirmatory factor analyses. Finally, a series of partial correlational analyses between the two subscales and scales assessing behavioral measures related to gambling supported the construct validity of the GPS. The present results suggest that the GPS is a useful scale for research on gambling.     

Mental health care for youth: Predictors of use are not always the same as predictors of volume

This study identifies determinants of adolescents’ propensity to use outpatient mental care as well as factors predicting number of visits after contact with a provider was made. We examined three types of treatment outlets: day treatment program (DTP), mental health clinic (MHC), and private specialty services (PSS). Among youth, 1.6% visited DTP, 2.3% visited MHC, and 11.1% had PSS, with overlaps in services utilization. Results from multivariable logistic regressions indicate that most of the individual characteristics differentiated youth on odds of using MHC and PSS, but not DTP. Health status, alcohol dependence, drug dependence, and problematic conduct behaviors and having Medicaid increased the odds of using all three services. Censored regressions used to model number of visits among service users found that girls consistently used more visits than boys. The results suggest that policies that encourage seeking help to a mental care provider may be in instances different from those aimed at motivating retention in treatment.     

The Gap Concept as a Quality of Life Measure: Validation Study of the Child Quality of Life Systemic Inventory

The objective was to determine the interest and psychometric properties of a new QOL self-assessment questionnaire suitable for children 8–12 years old measuring alpha, beta and gamma changes: the “Inventaire Systémique de Qualité de vie pour Enfants” (ISQV-E^©). This was a cross-sectional validation study. 288 children have completed the ISQV-E. Other tools were used: The “Autoquestionnaire de Qualité de Vie Enfants Imagé” (AUQUEI), the State-Trait Anxiety Inventory for Children (STAIC), the Children’s Depression Inventory (CDI). The internal consistency of the four scores of the ISQV-E (state, goal, rank and gap) is satisfactory. All scores have their own specificity. The data show the convergent validity, sensitivity and applicability of the ISQV-E. On the other hand, no satisfactory factorial structure was found although a multidimensional theoretical perspective was applied. The feasibility of the ISQV-E seems clearly demonstrated and the value of this new tool seems evident in contexts of physical, psychological or social problems. The validation study was promising but certain points such as test–retest reliability remain to be studied.     

Physiological Daily Inhalation Rates for Health Risk Assessment in Overweight/Obese Children,Adults, and Elderly

Physiological daily inhalation rates reported in our previous study for normal‐weight subjects 2.6–96 years old were compared to inhalation data determined in free‐living overweight/obese individuals (n = 661) aged 5–96 years. Inhalation rates were also calculated in normal‐weight (n = 408), overweight (n = 225), and obese classes 1, 2, and 3 adults (n = 134) aged 20–96 years. These inhalation values were based on published indirect calorimetry measurements (n = 1,069) and disappearance rates of oral doses of water isotopes (i.e., ²H₂O and H₂¹⁸O) monitored by gas isotope ratio mass spectrometry usually in urine samples for an aggregate period of over 16,000 days. Ventilatory equivalents for overweight/obese subjects at rest and during their aggregate daytime activities (28.99 ± 6.03 L to 34.82 ± 8.22 L of air inhaled/L of oxygen consumed; mean ±  SD) were determined and used for calculations of inhalation rates. The interindividual variability factor calculated as the ratio of the highest 99th percentile to the lowest 1st percentile of daily inhalation rates is higher for absolute data expressed in m³/day (26.7) compared to those of data in m³/kg‐day (12.2) and m³/m²‐day (5.9). Higher absolute rates generally found in overweight/obese individuals compared to their normal‐weight counterparts suggest higher intakes of air pollutants (in μg/day) for the former compared to the latter during identical exposure concentrations and conditions. Highest absolute mean (24.57 m³/day) and 99th percentile (55.55 m³/day) values were found in obese class 2 adults. They inhale on average 8.21 m³ more air per day than normal‐weight adults.     

Children’s Deliberate Control of Facial Action Units Involved in Sad and Happy Expressions

Few attempts have been made since the pioneer work of Ekman et al. (1980) to examine the development of the deliberate control of facial action units in children. We are reporting here two studies concerned with this issue. In Study 1, we investigated children’s ability to activate facial action units involved in sadness and happiness expressions as well as combinations of these action units. In Study 2, we examined children’s ability to pose happiness and sadness with their face, without telling them which action unit to activate. The children who took part in this study were simply asked to portray happiness and sadness as convincingly as possible. The results of Study 1 indicate a strong developmental progression in children’s ability to produce elementary facial components of both emotions as well as in their ability to produce a combination of the elements in the case of happiness. In agreement with prior research in motor development, several non-target action units were also activated when children performed the task. Their occurrence persisted throughout childhood, indicating limitations in the finer motor control achieved by children across age. The results obtained in Study 2 paralleled those obtained in Study 1 in many respects, providing evidence that the children used the technique of deliberate action to pose the two target emotions.     

Optimal life-cycle fertility in a Barro-Becker economy

Parenthood postponement is a key demographic trend of the last three decades. In order to rationalize that stylized fact, we extend the canonical model by Barro and Becker (Econometrica 57:481–501, 1989) to include two—instead of one—reproduction periods. We examine how the cost structure of early and late children in terms of time and goods affects the optimal fertility timing. Then, we identify conditions that guarantee the existence and uniqueness of a stationary equilibrium with a stationary cohort size. Finally, we examine how the model can rationalize the observed postponement of births, and we highlight two plausible causes: (1) a general rise in the cost of children in terms of goods and (2) a decline in the degree of family altruism.     

Fiscal Rules and Discretion Under Persistent Shocks

This paper studies the optimal level of discretion in policymaking. We consider a fiscal policy model where the government has time‐inconsistent preferences with a present bias toward public spending. The government chooses a fiscal rule to trade off its desire to commit to not overspend against its desire to have flexibility to react to privately observed shocks to the value of spending. We analyze the optimal fiscal rule when the shocks are persistent. Unlike under independent and identically distributed shocks, we show that the ex ante optimal rule is not sequentially optimal, as it provides dynamic incentives. The ex ante optimal rule exhibits history dependence, with high shocks leading to an erosion of future fiscal discipline compared to low shocks, which lead to the reinstatement of discipline. The implied policy distortions oscillate over time given a sequence of high shocks, and can force the government to accumulate maximal debt and become immiserated in the long run.     

Social cognitive neuroscience and leadership

We provide an overview of how the emerging field of social cognitive neuroscience can be linked to leadership theory and practice. A number of challenges are addressed, including theory development, as well as technical, measurement and methodological issues. In addition, we review recent leadership research that involves neuroscience applications, as well as areas that are closely related to leadership, such as emotional regulation and ethical reasoning and decision-making. Consideration is also given to how neuroscience might inform leadership development processes. We conclude with a discussion of the institutional challenges in conducting leadership research that incorporates neuroscience, and we consider potential limitations of such applications.     

POLITICAL AND ECONOMIC DETERMINANTS OF INTEREST RATE BEHAVIOR: ARE CENTRAL BANKS DIFFERENT?

Political influences on short-term interest rates in seventeen OECD countries from 1960–1990 are measured. After controlling for unexpected changes in inflation and unemployment, as well as changes in the world interest rate, short-term interest rates in most countries do not respond to political events, neither the timing of elections nor changes in the governing party. Thus, on this criterion, the central banks in this sample do not reveal large differences in their degree of independence from political influence. The small differences are not closely related to rankings of central bank independence based on quantification of central bank laws.
