Finding renewal in the midst of disaster: The case of the deepwater horizon oil spill

In 2010, the United States experienced the worst environmental disaster in its history. An explosion on a BP oilrig located in the Gulf of Mexico triggered the crisis. As a result, the United States coast guard and BP were charged with crisis communication in its response to the crisis. This essay provides an unprecedented examination and analysis of the communication experiences of public information officers who worked in the unified command center in Houma, Louisiana during the Deepwater Horizon oil spill response. The authors use the discourse of renewal theory to understand the communication practices and choices of the public information officers. Then, using the renewal framework, the authors present three implications for improving crisis communication research and practice.

Young children's perceptions and beliefs about hypothetical shy,unsociable, and socially avoidant peers at school

The aim of this study was to explore young children's perceptions, beliefs, and anticipated outcomes about different types of social withdrawal (shyness, unsociability, social avoidance). Participants were N = 212 children (n = 110 boys) aged 2.55–6.37 years (M = 4.86, SD = 0.89) recruited from three preschools and kindergartens in Italy. Children were interviewed individually and asked about hypothetical peers displaying different types of social withdrawal (i.e., shy, unsociable, socially avoidant) and for comparison purposes, aggressive and socially competent behaviors were also assessed. Among the three vignettes depicting types of withdrawn children, children rated the hypothetical shy peer as having the highest social motivations, the unsociable peer as receiving the least sympathy from others, and the avoidant peer as being the least intelligent and least liked by the teacher. In addition, girls reported wanting to play more with the shy peer than boys, and kindergarteners reported a higher affiliative preference for all subtypes of socially withdrawn peers than preschoolers. These findings suggest that Italian young children have a quite sophisticated ability to differentiate among the different social motivations and emotions that may underlie social withdrawal.     

The nation's drug problem is commercial recreational pharmacology

Overdose deaths, overprescribing of opioids, illicit production of fentanyl, a resurgence of methamphetamine and cocaine, and an epidemic of vaping‐related illnesses and substance use disorders cover the nation's headlines today, as they have for years. These problems are manifestations of commercial recreational pharmacology, the personally controlled use of psychoactive drugs that super‐stimulate brain reward for pleasure. While substance use and addiction have been known throughout history, the recent increasingly greater acceptance of commercial recreational pharmacology in the United States is exacting a toll on the public health of the nation. The most dramatic example is a decline in U.S. life expectancy, which fell three years in a row from 2016–2018 as a result of overdose deaths.     

A Simple Toxicokinetic Model Exhibiting Complex Dynamics and Nonlinear Exposure Response

Uncertainty in model predictions of exposure response at low exposures is a problem for risk assessment. A particular interest is the internal concentration of an agent in biological systems as a function of external exposure concentrations. Physiologically based pharmacokinetic (PBPK) models permit estimation of internal exposure concentrations in target tissues but most assume that model parameters are either fixed or instantaneously dose-dependent. Taking into account response times for biological regulatory mechanisms introduces new dynamic behaviors that have implications for low-dose exposure response in chronic exposure. A simple one-compartment simulation model is described in which internal concentrations summed over time exhibit significant nonlinearity and nonmonotonicity in relation to external concentrations due to delayed up- or downregulation of a metabolic pathway. These behaviors could be the mechanistic basis for homeostasis and for some apparent hormetic effects.     

Career Decision State and Assessment of RIASEC Interest Structure

The career decision state (CDS) was studied in relation to RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) profiles in Self-Directed Search results among college students (86 women, 27 men). Three CDS dimensions measured by the Career State Inventory (CSI; certainty, satisfaction, and clarity) were examined as predictors of RIASEC primary and secondary constructs. Significant, albeit modest, zero-order correlations (p < .05) emerged between clarity and 3 secondary constructs (i.e., consistency, commonness, and coherence). Results of regression analyses indicated that CSI dimensions predicted 1 secondary construct (i.e., commonness).     

The Principles and Ethics of Including Children with Disability in Child Research

This paper provides a set of principles and ethics, developed in collaboration between Pacific‐ and Australian‐based researchers, to guide research practice in a project enabling the self‐reporting of children with disability in Vanuatu and Papua New Guinea (PNG). The paper presents both a summary of academic literature relating to these principles and ethics, as well as their succinct ‘translation’ into a set of action statements for researchers working with children with disability. The paper offers a base for further development by others to guide research practice and foster the autonomous participation of children with disability in developing countries.
