REVIEW
Aaron L Pincus
This paper links Criterion A of the Diagnostic and Statistical Manual of Mental Disorders-5th Edition Alternative Model for Personality Disorders with the contemporary interpersonal model of personality pathology. Advances in interpersonal theory and assessment are outlined to demonstrate that Criterion A's self (identity, self-direction) and interpersonal (empathy, intimacy) impairments are related to the interpersonal meta-constructs and agency and communion and are operationalized by perceptual, behavioral, and affective mechanisms of the interpersonal situation framework...

Irina Trofimova
The Functional Constructivism (FC) paradigm is an alternative to behaviorism and considers behavior as being generated every time anew, based on an individual's capacities, environmental resources and demands. Walter Freeman's work provided us with evidence supporting the FC principles. In this paper we make parallels between gradual construction processes leading to the formation of individual behavior and habits, and evolutionary processes leading to the establishment of biological systems. Referencing evolutionary theory, several formal descriptors of such processes are proposed...

Andrew C Bonner, John C Borrero
Differential-reinforcement-of-low-rate (DRL) schedules are reinforcement contingencies designed to reduce response rates. A common variation of the DRL arrangement is known as full-session DRL ( f-DRL), in which a reinforcer is presented at the end of an interval if the response rate during that interval is below a predetermined criterion. Prior human operant research involving arbitrary mouse clicks has shown that the f-DRL is likely to reduce target responding to near zero rates. Similarly, applied research has shown that the f-DRL is likely to reduce minimally disruptive classroom behavior...

Brandon M Wild, Rahul Mohan, Renée Morris
In the rat, the rubrospinal tract (RST) is a descending motor pathway involved in the production of skilled reaching movement. The RST originates in the red nucleus in the midbrain and runs down the spinal cord in the lateral-most aspect of the dorsolateral funiculus (DLF). The RST makes monosynaptic contact with interneurons within the intermediate laminae of the cord, however a contingent of RST axons constitutes direct supraspinal input for spinal cord motor neurons. The current study investigated the effects of unilateral RST transection at cervical levels C3-4 on the population of motor neurons in both spinal segments C5-6 and L2-3...

BACKGROUND: Legal difficulties and cocaine use are prevalent in methadone maintenance patients, and they are related to one another, as well as to poor response to methadone treatment. Contingency management (CM) is efficacious for decreasing cocaine use, but the relation of CM treatment to criminal activities has rarely been studied. METHODS: This study evaluated whether baseline legal problems are related to subsequent substance use and illegal activities for cocaine using methadone maintained patients and whether CM differentially improves outcomes depending on baseline legal problems...

U.S. military and allied contingency operations are increasingly occurring in locations with limited, unstable or compromised fresh water supplies. Non-potable graywater reuse is currently under assessment as a viable means to increase mission sustainability while significantly reducing the resources, logistics and attack vulnerabilities posed by transport of fresh water. Development of health-based (non-potable) exposure guidelines for the potential microbial components of graywater would provide a logical and consistent human-health basis for water reuse strategies...

BACKGROUND: Evidence of association of ambient air pollution with cause-specific emergency department visits in China is still limited. This study aimed to investigate short-term associations between exposures to air pollutants and daily cause-specific emergency department visits using a large-scale multicenter database involving a total of 65 sentinel hospitals in Guangzhou, the most densely-populated city in south China, during 2013-2015. MATERIAL AND METHODS: We obtained data on 162,771 emergency department visits from 65 hospitals from the Emergency Medical Command Center in Guangzhou between January 1, 2013 and December 31, 2015...

BACKGROUND AND OBJECTIVES: Previous studies have emphasized the importance of effectual communication during patient handoffs. The objectives of this study were to (1) implement a resident-driven quality improvement project to improve handoffs by including key elements that are necessary for a safe and effective handoff. We chose to use the IPASS (illness severity, patient summary, action items, situation awareness and contingency planning, synthesis by receiver) mnemonic as our standardized handoff model; (2) Consider balancing measures in an effort to be aware of any negative effects of our interventions on resident satisfaction with the system...

Derick T Wade
Current management of people with prolonged disorders of consciousness is failing patients, families and society. The causes include a general lack of concern, knowledge and expertise; a legal and professional framework which impedes timely and appropriate decision-making and/or enactment of the decision; and the exclusive focus on the patient, with no legitimate means to consider the broader consequences of healthcare decisions. This article argues that a clinical pathway based on the principles of (a) the English Mental Capacity Act 2005 and (b) using time-limited treatment trials could greatly improve patient management and reduce stress on families...

We examined the use of a paired-stimulus, video-based preference assessment (VPA) to identify high- and low-preference social interactions for three children with autism spectrum disorder. We conducted two VPAs with each participant: one with access to the interaction contingent on each selection and one without access. We also conducted a concurrent-operant reinforcer assessment to evaluate the accuracy of the VPAs in identifying reinforcers. For two participants, the VPAs corresponded strongly and the results of the reinforcer assessment suggest that the high-preference interaction produced more of the target response than the low-preference interaction...

Tobin D Northfield, Brandon T Barton, Oswald J Schmitz
Predator-prey interaction is inherently spatial because animals move through landscapes to search for and consume food resources and to avoid being consumed by other species. The spatial nature of species interactions necessitates integrating spatial processes into food web theory and evaluating how predators combine to impact their prey. Here, we present a spatial modeling approach that examines emergent multiple predator effects on prey within landscapes. The modeling is inspired by the habitat domain concept derived from empirical synthesis of spatial movement and interactions studies...

A reduction in population size due to habitat fragmentation can alter the relative roles of different evolutionary mechanisms in phenotypic trait differentiation. While deterministic (selection) and stochastic (genetic drift) mechanisms are expected to affect trait evolution, genetic drift may be more important than selection in small populations. We examined relationships between mature adult traits and ecological (abiotic and biotic) variables among 14 populations of brook trout. These naturally fragmented populations have shared ancestry but currently exhibit considerable variability in habitat characteristics and population size (49 < Nc < 10,032; 3 < Nb < 567)...

Raffaele De Luca Picione, Jaan Valsiner
In this paper we discuss the semiotic functions of the psychological borders that structure the flow of narrative processes. Each narration is always a contextual, situated and contingent process of sensemaking, made possible by the creation of borders, such as dynamic semiotic devices that are capable of connecting the past and the future, the inside and the outside, and the me with the non-me. Borders enable us to narratively construct one's own experiences using three inherent processes: contextualization, intersubjective positioning and setting of pertinence...

Small-scale keepers are less likely to engage with production organisations and may therefore be less aware of legislation, rules and biosecurity practices which are implemented in the livestock sector. Their role in the transmission of endemic and exotic diseases is not well studied, but is believed to be important. The authors use small-scale pig keepers in Scotland as an example of how important small-scale livestock keepers might be for national biosecurity. In Scotland more than two thirds of pig producers report that they keep less than 10 pigs, meaning that biosecurity practices and pig health status on a substantial number of holdings are largely unknown; it is considered important to fill this knowledge gap...

Using a dual-process model (DPM) framework, this research examined whether right-wing authoritarianism (RWA) and social dominance orientation (SDO) are differentially associated with adolescent delinquency. In Study 1 ( N = 847; Mage = 15.96) and Study 2 ( N = 340; Mage = 16.64), adolescents completed measures of RWA, SDO, and engagement in different forms of delinquency. In Study 2, adolescents also reported their beliefs about obeying different laws. Across both studies, adolescents who endorsed greater RWA engaged in lower levels of delinquency and those who endorsed greater SDO engaged in higher levels of delinquency...

Financial success is an important goal, yet striving for it is often associated with negative outcomes. One reason for this paradox is that financial pressures may be tied to basing self-worth on financial success. Studies 1a to 1c developed a measure of Financial Contingency of Self-Worth (Financial CSW), and found that it predicted more financial social comparisons, financial hassles, stress, anxiety, and less autonomy. In response to a financial (vs. academic) threat, higher Financial CSW participants experienced less autonomy, perceived financial problems more negatively, and disengaged from their financial problems (Study 2)...

Although trichotillomania (TTM), skin picking (SP), and nail biting (NB) have been receiving growing scientific attention, the question as to whether these disorders can be regarded as separate entities or they are different manifestations of the same underlying tendency is unclear. Data were collected online in a community survey, yielding a sample of 2705 participants (66% women, mean age: 29.1, SD: 8.6). Hierarchical factor analysis was used to identify a common latent factor and the multiple indicators and multiple causes (MIMIC) modelling was applied to test the predictive effect of borderline personality disorder symptoms, impulsivity, distress and self-esteem on pathological grooming...

To understand why molecular evolution turned out as it did, we must characterize not only the path that evolution followed across the space of possible molecular sequences but also the many alternative trajectories that could have been taken but were not. A large-scale comparison of real and possible histories would establish whether the outcome of evolution represents an optimal state driven by natural selection or the contingent product of historical chance events; it would also reveal how the underlying distribution of functions across sequence space shaped historical evolution...

This article shows how funding research on Alzheimer's disease became a priority for the British Medical Research Council (MRC) in the late 1970s and 1980s, thanks to work that isolated new pathological and biochemical markers and showed that the disease affected a significant proportion of the elderly population. In contrast to histories that focus on the emergence of new and competing theories of disease causation in this period, I argue that concerns over the use of different assessment methods ensured the MRC's immediate priority was standardising the ways in which researchers identified and recorded symptoms of Alzheimer's disease in potential research subjects...

Despite the importance of including children's preferences in the valuation of their own health benefits, no study has investigated the ability of children to understand willingness-to-pay (WTP) questions. Using a contingent valuation method, we elicit children's and parents' WTP to reduce children's risk of an asthma attack. Our results suggest that children are able to understand and value their own health risk reductions, and their ability to do so improves with age. Child age was found to be inversely related to parents' and children's WTP...
