Naixue Cui, Janet A Deatrick, Jianghong Liu
Although there is a substantial amount of literature documenting the relationship between child abuse and behavioral problems in China, there is, on the other hand, a limited number of studies on the joint and unique associations of maternal and paternal physical abuse with child behaviors within the Chinese context. The present study, using the family systems theory as the theoretical framework, aims to examine these joint and the unique associations of maternal and paternal physical abuse with externalizing and internalizing behaviors among a community sample of Chinese children...

REVIEW
Anita Minh, Nazeem Muhajarine, Magdalena Janus, Marni Brownell, Martin Guhn
This paper describes a scoping review of 42 studies of neighborhood effects on developmental health for children ages 0-6, published between 2009 and 2014. It focuses on three themes: (1) theoretical mechanisms that drive early childhood development, i.e. how neighborhoods matter for early childhood development; (2) dependence of such mechanisms on place-based characteristics i.e. where neighborhood effects occur; (3) dependence of such mechanisms on child characteristics, i.e. for whom is development most affected...

High-throughput technology like microarrays is widely used in the inference of gene regulatory networks (GRNs). We focused on time series data since we are interested in the dynamics of GRNs and the identification of dynamic networks. We evaluated the amount of information that exists in artificial time series microarray data and the ability of an inference process to produce accurate models based on them. We used dynamic artificial gene regulatory networks in order to create artificial microarray data. Key features that characterize microarray data such as the time separation of directly triggered genes, the percentage of directly triggered genes and the triggering function type were altered in order to reveal the limits that are imposed by the nature of microarray data on the inference process...

BACKGROUND: Ghana's socio-cultural landscape proscribes suicidal behaviour, and this has serious ramifications for attempt survivors and their families. The objective of this qualitative study was to understand the experiences of the families of attempt survivors and how they cope with the aftermath of the attempt. METHODS: Ten families with attempted suicides agreed to participate in the study, hence they were interviewed. The information gathered was manually analyzed according to Interpretative Phenomenological Analysis (IPA) resulting in three major thematic areas...

Protein phosphorylation plays a critical role in human body by altering the structural conformation of a protein, causing it to become activated/deactivated, or functional modification. Given an uncharacterized protein sequence, can we predict whether it may be phosphorylated or may not? This is no doubt a very meaningful problem for both basic research and drug development. Unfortunately, to our best knowledge, so far no high throughput bioinformatics tool whatsoever has been developed to address such a very basic but important problem due to its extremely complexity and lacking sufficient training data...

Background: We currently still lack valid methods to dynamically measure resilience for stressors before the appearance of adverse health outcomes that hamper well-being. Quantifying an older adult's resilience in an early stage would aid complex decision-making in health care. Translating complex dynamical systems theory to humans, we hypothesized that three dynamical indicators of resilience (variance, temporal autocorrelation, and cross-correlation) in time series of self-rated physical, mental, and social health were associated with frailty levels in older adults...

This article relates the findings of a discourse analysis of an online asynchronous interprofessional learning initiative involving two UK universities. The impact of the initiative is traced over three intensive periods of online interaction, each of several-weeks duration occurring over a three-year period, through an analysis of a random sample of discussion forum threads. The corpus of rich data drawn from the forums is interpreted using ecological systems theory, which highlights the complexity of interaction of individual, social and cultural elements...

The PARENTED outline (a mnemonic device) and the companion Parenting Landscape handout are proposed tools for clinical use that were developed as an outgrowth of clinical experience with hospitalized pediatric mental health patients and their families in combination with family systems theories of Minuchin and Bowen, Ainsworth and Bowlby's attachment theory, and Erikson's stages of development. The tools contain eight categories of observable, typical family interactions that a nurse on an inpatient mental health unit may encounter...

The emergence of the complexity characterizing our systems of systems (SoS) requires a reevaluation of the way we model, assess, manage, communicate, and analyze the risk thereto. Current models for risk analysis of emergent complex SoS are insufficient because too often they rely on the same risk functions and models used for single systems. These models commonly fail to incorporate the complexity derived from the networks of interdependencies and interconnectedness (I-I) characterizing SoS. There is a need to reevaluate currently practiced risk analysis to respond to this reality by examining, and thus comprehending, what makes emergent SoS complex...

With health disparities still pervasive and persistent in the United States, medical researchers and social scientists continue to develop recruitment strategies to increase the inclusion of racial/ethnic minority groups in research and interventions. Effective methods for recruiting samples of African American participants for pediatric research may be best understood when situated within an overarching conceptual model-one that serves to organize and explain effective recruitment strategies. A theoretical framework well suited for this purpose is Bronfenbrenner's ecological systems theory, which views individuals as influencing and being influenced by (both directly and indirectly) a series of interconnected social systems...

Open-ended evolution (OEE) is relevant to a variety of biological, artificial and technological systems, but has been challenging to reproduce in silico. Most theoretical efforts focus on key aspects of open-ended evolution as it appears in biology. We recast the problem as a more general one in dynamical systems theory, providing simple criteria for open-ended evolution based on two hallmark features: unbounded evolution and innovation. We define unbounded evolution as patterns that are non-repeating within the expected Poincare recurrence time of an isolated system, and innovation as trajectories not observed in isolated systems...

Kristin Turney, Sarah Halpern-Meekin
Family systems theory points to the interconnected nature of dyadic relationships within the family unit, arguing for attention to how the parental relationship shapes their ties to and interactions with their children. Grounded in family systems theory, we consider how relationship churning-defined as being in an on-again/off-again relationship with the same partner-is associated with father involvement. We use data from the Fragile Families and Child Wellbeing Study to examine how father involvement among relationship churners compares with father involvement among those in three other relationship types (measured during the first five years of the focal child's life): stably together relationships, stably broken-up relationships, and repartnered relationships...

A methodology was defined and developed for designing theory-based behaviour change systems for health promotion that can be tailored to the individual. Theories from two research fields were combined with a participatory action research methodology. Two case studies applying the methodology were conducted. During and between group sessions the participants created material and designs following the behaviour change strategy themes, which were discussed, analysed and transformed into a design of a behaviour change system...

Cellular signaling systems precisely transmit information in the presence of molecular noise while retaining flexibility to accommodate the needs of individual cells. To understand design principles underlying such versatile signaling, we analyzed the response of the tumor suppressor p53 to varying levels of DNA damage in hundreds of individual cells and observed a switch between distinct signaling modes characterized by isolated pulses and sustained oscillations of p53 accumulation. Guided by dynamic systems theory we show that this requires an excitable network structure comprising positive feedback and provide experimental evidence for its molecular identity...

A growing body of research suggests that bipolar spectrum disorders (BSDs) are associated with high aggression. However, little research has prospectively examined how aggression may affect time to onset of hypomanic/manic versus major depressive episodes. In a longitudinal study, we tested the hypothesis that aggression would prospectively predict a shorter time to the onset of hypomanic/manic episodes and a longer time to the onset of major depressive episodes, based on the behavioral approach system theory of BSDs...

Objectives: Functionalist emotion and ecological systems theories suggest emodiversity-the variety and relative abundance of individuals' emotion experiences-is beneficial for psychological and physical health and may change with age. This paper examines and provides recommendations for operationalization of diversity-type intraindividual variability (IIV) constructs using intensive longitudinal data, and demonstrates the utility of emodiversity by examining its links to physical health moderated by mean levels of emotion and age...

Dan Zhang, Qing-Guo Wang, Dipti Srinivasan, Hongyi Li, Li Yu
This paper is concerned with the asynchronous state estimation for a class of discrete-time switched complex networks with communication constraints. An asynchronous estimator is designed to overcome the difficulty that each node cannot access to the topology/coupling information. Also, the event-based communication, signal quantization, and the random packet dropout problems are studied due to the limited communication resource. With the help of switched system theory and by resorting to some stochastic system analysis method, a sufficient condition is proposed to guarantee the exponential stability of estimation error system in the mean-square sense and a prescribed $H∞ performance level is also ensured...

Importance: In recent years, there has been increased focus on subthreshold stages of mental disorders, with attempts to model and predict which individuals will progress to full-threshold disorder. Given this research attention and the clinical significance of the issue, this article analyzes the assumptions of the theoretical models in the field. Observations: Psychiatric research into predicting the onset of mental disorder has shown an overreliance on one-off sampling of cross-sectional data (ie, a snapshot of clinical state and other risk markers) and may benefit from taking dynamic changes into account in predictive modeling...

Over the last decade, we have observed a revolution in brain structural and functional Connectomics. On one hand, we have an ever-more detailed characterization of the brain's white matter structural connectome. On the other, we have a repertoire of consistent functional networks that form and dissipate over time during rest. Despite the evident spatial similarities between structural and functional connectivity, understanding how different time-evolving functional networks spontaneously emerge from a single structural network requires analyzing the problem from the perspective of complex network dynamics and dynamical system's theory...
