Don’t Fret, Be Supportive! Maternal Characteristics Linking Child Shyness to Psychosocial and School Adjustment in Kindergarten

Abstract: The goal of this study was to explore the moderating role of maternal personality and parenting characteristics in the links between shyness and adjustment in kindergarten. Participants were 197 children enrolled in kindergarten programs (and their mothers and teachers). Multisource assessment was employed, including maternal ratings, behavioral observations, teacher ratings, and individual child interviews. Results indicated that shyness was associated with a wide range of socio-emotional and school adjustment difficulties in kindergarten. Moreover, support for the moderating role of parenting was also found. Relations between shyness and certain indices of maladjustment were stronger among children with mothers characterized by higher neuroticism, BIS sensitivity, and an overprotective parenting style, and weaker for mothers characterized by high agreeableness and an authoritative parenting style.

What size is a biologically relevant landscape

Abstract: The spatial extent at which landscape structure best predicts population response, called the scale of effect, varies across species. An ability to predict the scale of effect of a landscape using species traits would make landscape study design more efficient and would enable landscape managers to plan at the appropriate scale. We used an individual based simulation model to predict how species traits influence the scale of effect. Specifically, we tested the effects of dispersal distance, reproductive rate, and informed movement behavior on the radius at which percent habitat cover best predicts population abundance in a focal area. Scale of effect for species with random movement behavior was compared to scale of effect for species with three (cumulative) levels of information use during dispersal: habitat based settlement, conspecific density based settlement, and gap-avoidance during movement. Consistent with a common belief among researchers, dispersal distance had a strong, positive influence on scale of effect. A general guideline for empiricists is to expect the radius of a landscape to be 4–9 times the median dispersal distance or 0.3–0.5 times the maximum dispersal distance of a species. Informed dispersal led to greater increases in population size than did increased reproductive rate. Similarly, informed dispersal led to more strongly decreased scales of effect than did reproductive rate. Most notably, gap-avoidance resulted in scales that were 0.2–0.5 times those of non-avoidant species. This is the first study to generate testable hypotheses concerning the mechanisms underlying the scale at which populations respond to the landscape.

Discrete-Event Modeling and Simulation: A Practitioner's Approach

Abstract: Complex artificial dynamic systems require advanced modeling techniques that can accommodate their asynchronous, concurrent, and highly non-linear nature. Discrete Event systems Specification (DEVS) provides a formal framework for hierarchical construction of discrete-event models in a modular manner, allowing for model re-use and reduced development time.Discrete Event Modeling and Simulation presents a practical approach focused on the creation of discrete-event applications. The book introduces the CD++ tool, an open-source framework that enables the simulation of discrete-event models. After setting up the basic theory of DEVS and Cell-DEVS, the author focuses on how to use the CD++ tool to define a variety of models in biology, physics, chemistry, and artificial systems. They also demonstrate how to map different modeling techniques, such as Finite State Machines and VHDL, to DEVS. The in-depth coverage elaborates on the creation of simulation software for DEVS models and the 3D visualization environments associated with these tools.A much-needed practical approach to creating discrete-event applications, this book offers world-class instruction on the fields most useful modeling tools.

Procrastination and the priority of short‐term mood regulation: Consequences for future self.

Abstract: Procrastination is a common and pervasive problem associated with a range of negative outcomes across a variety of life domains that often occurs when people are faced with tasks that are seen as aversive. In this paper, we argue that as a form of self-regulation failure, procrastination has a great deal to do with short-term mood repair and emotion regulation. Moreover, we contend that a temporal understanding of self and the mood-regulating processes involved in goal pursuit is particularly important in understanding procrastination, because the consequences of procrastination are typically borne by the future self. After summarizing the research on the priority of short-term mood regulation in procrastination, we then draw the connection between the focus on short-term mood repair and the temporal disjunction between present and future selves. We present research that exemplifies these intra-personal processes in understanding temporal notions of self characterized by procrastination, and then link these processes to the negative consequences of procrastination for health and well-being. We conclude with a discussion of possible avenues for future research to provide further insights into how temporal views of the self are linked to the dynamics of mood regulation over time in the context of procrastination. © 2013 Blackwell Publishing Ltd.
