Are time and money equally substitutable for all commodity groups in the household’s domestic production?

Review of Economics of the Household - This article uses time-use and household expenditure data to measure the substitutability between time and money within the Beckerian household production...     

A generalized ordered Probit model

Abstract

The ordered probit and logit models, based on the normal and logistic distributions, can yield biased and inconsistent estimators when the distributions are misspecified. A generalized ordered response model is introduced which can reduce the impact of distributional misspecification. An empirical exploration of various determinants of life satisfaction suggests possible benefits of allowing for diverse distributional characteristics. These improvements are confirmed using a Monte Carlo study to contrast the performance of the flexible parametric specifications to the probit and logit specifications.     

Infants’ Style of Emotion Regulation with Their Mothers and Fathers: Concordance between Parents and the Contribution of Father–Infant Interaction Quality

The concordance between infants’ emotion regulation styles with different partners has not been consistently analysed nor have the relational correlates of such potential across‐partners similarities. We explored these issues by assessing 10‐month‐olds’ (59.6 percent boys) emotion regulation styles separately with mother and father and by evaluating mother–infant and father–infant interaction quality. The sample consisted of 50 low‐risk families. Two home visits were conducted and similar procedures were adopted for each visit. Parent–infant interaction quality was assessed during daily routines and during free play; both parents independently completed a temperament questionnaire. Infant emotion regulation was assessed in a semi‐structured problem‐solving task: adaptive vs. maladaptive (under and over‐regulation) styles. As predicted, infants’ emotion regulation with their mothers and fathers were related. However, only father–infant interaction quality predicted infants’ emotion regulation concordance: lower interaction quality was associated with maladaptive concordance compared with non‐concordance and higher interaction quality was associated with adaptive concordance compared with non‐concordance. Our results support the claim that by the end of the first year of life, infants use similar emotion regulation styles with mother and father and point to father–infant interaction as an important correlate of emotion regulation across‐parents.     

A Preliminary Investigation of Risks for Adverse Outcomes of Relationship Seeking on Social Network Sites (SNS): A Descriptive Study of Women Over 50 Seeking Relationships on MySpace in Hillsborough County,Florida

In contrast to younger populations, little attention has been paid to the increase in seniors using Internet-based venues to find relationships and the potential risk for adverse outcomes this poses. This study examined data collected via an online survey from 45 ethnically diverse women aged 50+ “seeking relationships” on MySpace. The majority of women reported a relationship with someone they met online (85%). They also reported experiencing adverse events including financial exploitation (40%), threats (55%), and physical harm (38%) by someone they met online at levels greater than traditional relationship seeking in the general population. Directions for future research are explored.     

Procedure to identify outliers through cumulative distribution of extremes in a Gamma response model

This work aimed at proposing a procedure based on the cumulative distribution of maximums and minimums to identify outliers in generalized Gamma-response models. In order to validate such method, we used simulations scenarios defined by the combination of different samples, contamination rate and distributions with different degrees of asymmetry. In this context, probabilities related to errors in classification and accuracy were obtained by carrying by Monte Carlo simulations. Using cumulative distribution of extremes to identify outliers in a Gamma-response model is recommended, since it is not likely to present errors and was highly accurate in all assessed scenarios.     

Educating collaborative planners: strengthening evidence for the learning potential of multi-stakeholder regional learning environments

Abstract

Planning education needs effective learning environments that support students’ boundary crossing competence development. The multi-stakeholder regional learning environment (RLE) is, by its typical design, hypothesized to foster boundary crossing. This quasi-experimental mixed method pre- and post-test study affirms the effectiveness of the RLE for stimulating competence development, and specifically shows the added value of three typical ‘boundary crossing’ RLE design characteristics, i.e. working in multidisciplinary student groups, working intensively with multiple stakeholders, and a high coaching intensity. Results strengthen previous findings, and contribute to the debate in planning education on an evidence-based pedagogical fundament for commonly used authentic learning environments.     

Gender differences in the impact of leadership styles on subordinate embeddedness and job satisfaction

It is not surprising that subordinates generally prefer high-quality relationships with their supervisors. However, gender may influence the specific characteristics subordinates use to make this judgment, thereby impacting important downstream workplace processes and outcomes. Drawing from Social Role Theory, we use moderated mediation analyses across two independent samples to show that communally oriented leader–member exchange (LMX) dimensions (i.e., Affect and Loyalty) positively influence the job embeddedness of female (but not male) subordinates, whereas agentically oriented LMX dimensions (i.e., Professional Respect and Contribution) influence both genders equally. We found these effects despite strong LMX facet intercorrelations (ranging from r = .68 to .81), thereby highlighting the utility of testing theoretically driven dimensional effects, even when facets overlap significantly.     

Understanding the Nature and Extent of Farm and Ranch Diversification in North America*

Abstract Pressure to adopt enhanced production technologies, changing government support policies, increasing and more diverse competition, and changing markets have posed economic challenges to North American farmers over the past two decades. As a response, farmers are adjusting their production model by incorporating agricultural related enterprises. Although there is evidence that farm diversification is occurring throughout North America, there is a dearth of scientific information regarding the types of enterprises being developed and used in this context. This study aims to fill this void by exploring the extent of farm diversification by identifying and describing eight types of enterprises that farmers and ranchers are using. It was found that levels of diversification are often dependent on operating and management attributes and owner characteristics, such as the number of family members working on the farm and the number of days that the farmer's spouse works off the farm.
