#1
O Nafcha, E T Higgins, B Eitam
Motivated behavior is considered to be a product of integration of a behavior's subjective benefits and costs. As such, it is unclear what motivates "habitual behavior" which occurs, by definition, after the outcome's value has diminished. One possible answer is that habitual behavior continues to be selected due to its "intrinsic" worth. Such an explanation, however, highlights the need to specify the motivational system for which the behavior has intrinsic worth. Another key question is how does an activity attain such intrinsically rewarding properties...

P-Y Oudeyer, J Gottlieb, M Lopes
This chapter studies the bidirectional causal interactions between curiosity and learning and discusses how understanding these interactions can be leveraged in educational technology applications. First, we review recent results showing how state curiosity, and more generally the experience of novelty and surprise, can enhance learning and memory retention. Then, we discuss how psychology and neuroscience have conceptualized curiosity and intrinsic motivation, studying how the brain can be intrinsically rewarded by novelty, complexity, or other measures of information...

Roberto Victor Pavarino
Two high-level multisectoral global conferences on road traffic safety (Moscow, 2009 and Brasilia, 2015), held under the auspices of the United Nations, adopted formal declarations on both occasions. Given the potential of these documents to establish positions, propose guidelines, policies and legal frameworks, this paper compares these charters, in order to identify the emphases, expectations and horizons indicated at each moment, highlighting their health-related items. We describe the WHO's involvement with road safety, considering the ways this relationship signaled the health sector's connection with the theme...

In the Netherlands in 2006 a major health care reform was introduced, aimed at reinforcing regulated competition in the health care sector. Health insurers were provided with strong incentives to compete and more room to negotiate and selectively contract with health care providers. Nevertheless, the bargaining position of health insurers vis-à-vis both GPs and hospitals is still relatively weak. GPs are very well organized in a powerful national interest association (LHV) and effectively exploit the long-standing trust relationship with their patients...

Relative position in a social hierarchy, or subjective social status, has been associated with indicators of socioeconomic status and may be influenced by social connectedness. The primary purpose of this study is to explore the relationship between health insurance status and subjective social status, using the MacArthur Scale of Subjective Social Status (SSS, community version), in the state of Hawai'i with its highly insured population. The secondary purpose is to examine other social determinants that influence social status, including social connectedness...

Laurel A Screven, Micheal L Dent
Mice often produce ultrasonic vocalizations (USVs) that sweep upwards in frequency from around 60 to around 80 kHz and downwards in frequency from 80 to 60 kHz. Whether or not these USVs are used for communication purposes is still unknown. Here, mice were trained and tested using operant conditioning procedures and positive reinforcement to discriminate between synthetic upsweeps and downsweeps. The stimuli varied in bandwidth, duration, and direction of sweep. The mice performed significantly worse when discriminating between background and test stimuli when the stimuli all occupied the same bandwidths...

The use of performance-enhancing drugs (PED) is common among Iranian professional athletes. As this phenomenon is a social problem, the main purpose of this research is to explain why athletes engage in "doping" activity, using social learning theory. For this purpose, a sample of 589 professional athletes from Rasht, Iran, was used to test assumptions related to social learning theory. The results showed that there are positive and significant relationships between the components of social learning theory (differential association, differential reinforcement, imitation, and definitions) and doping behavior (past, present, and future use of PED)...

Juliana Lopez Marulanda, Olivier Adam, Fabienne Delfour
Bottlenose dolphins are highly social cetaceans with an extensive sound production including clicks, burst-pulsed sounds, and whistles. Some whistles, known as signature whistles, are individually specific. These acoustic signatures are commonly described as being emitted in contexts of stress during forced isolation and as group cohesion calls. Interactions between humans and captive dolphins is largely based on positive reinforcement conditioning within several training/feeding sessions per day. Vocal behavior of dolphins during these interactions might vary...

OBJECTIVES: Few studies have investigated service user satisfaction with cognitive behavioural therapy for psychosis (CBTp). This study explored its associations with clinical presentation and outcomes, retrospective expectations of progress, perceptions of the therapist, and demographic variables. DESIGN AND METHODS: One hundred and sixty-five service users completed self-report questionnaires pre- and post-CBTp in relation to the constructs of interest. Regression analyses explored associations with (1) overall satisfaction with therapy and (2) perceived progress, skills, and knowledge gained...

Abuse of synthetic psychostimulants like synthetic cathinones has risen in recent years. 3,4-Methylenedioxypyrovalerone (MDPV) is one such synthetic cathinone that demonstrates a mechanism of action similar to cocaine. Compared to cocaine, MDPV is more potent at blocking dopamine and norepinephrine reuptake and is readily self-administered by rodents. The present study compared the rewarding and reinforcing properties of MDPV and cocaine using systemic injection dose-response and self-administration models...

A nullomer is an oligomer that does not occur as a subsequence in a given DNA sequence, i.e. it is an absent word of that sequence. The importance of nullomers in several applications, from drug discovery to forensic practice, is now debated in the literature. Here, we investigated the nature of nullomers, whether their absence in genomes has just a statistical explanation or it is a peculiar feature of genomic sequences. We introduced an extension of the notion of nullomer, namely high order nullomers, which are nullomers whose mutated sequences are still nullomers...

BACKGROUND: The international literature is unclear regarding the analgesic efficacy of the transversus abdominis plane block (TAPB) after a Caesarean section (CS). OBJECTIVES: The aim of this study was to determine whether a correctly performed ultrasound-guided TAPB (USG-TAPB) could provide better control of acute postoperative pain during the first 72 hours after CS and if it could provide a faster postoperative recovery. STUDY DESIGN: A double-blind, randomized, controlled clinical trial on pregnant women who underwent CS...

BACKGROUND: Wearable activity trackers (trackers) are increasingly popular devices used to track step count and other health indicators. Trackers have the potential to benefit those in need of increased physical activity, such as adults who are older and face significant health challenges. These populations are least likely to purchase trackers and most likely to face challenges in using them, yet may derive educational, motivational, and health benefits from their use once these barriers are removed...

Preterm labor is often a sudden event that impacts significantly on the health of the premature infant and on parenting behaviors. The prognosis for premature infants correlates positively with the effectiveness of parenting. Therefore, encouraging parental functions is important. The present paper reviews the literature on the concept of family-centered care in the contexts of premature-infant health problems, assesses the impacts of preterm birth on the parental role, and assesses the influences of parental dysfunction...

Two experiments were conducted to characterize the progression of deoxynivalenol (DON)-induced growth suppression and to investigate algae-modified montmorillonite clay (AMMC) as a means to alleviate the effects of DON in nursery pigs. In both experiments, naturally DON-contaminated wheat was used to produce diets with desired DON levels. In Exp. 1, 280 barrows and gilts (10.0 ± 0.2 kg BW) were used in a 28-d experiment arranged in a 2 × 2 + 1 factorial design with 8 replicates per treatment. The 5 treatments consisted of 2 positive control (PC) diets with DON below detection limits and with or without 0 or 0...

#19
Aaron J Gruber, Rajat Thapa
The propensity of animals to shift choices immediately after unexpectedly poor reinforcement outcomes is a pervasive strategy across species and tasks. We report here that the memory supporting such lose-shift responding in rats rapidly decays during the intertrial interval and persists throughout training and testing on a binary choice task, despite being a suboptimal strategy. Lose-shift responding is not positively correlated with the prevalence and temporal dependence of win-stay responding, and it is inconsistent with predictions of reinforcement learning on the task...

Styrene is a building-block of several compounds used in a wide array of materials and products. The most important human exposure to this substance occurs in industrial settings, especially among reinforced-plastics industry workers. The effect of occupational exposure to styrene on cytogenetics biomarkers has been previously reviewed with positive association observed for chromosomal aberrations, and inconclusive data for the micronucleus assay. Some limitations were noted in those studies, including inadequate exposure assessment and poor epidemiological design...
