Abstract
Background and aims
Social-networks-use disorder is discussed as a potential further type of disorders due to addictive behaviors. Theoretical models assume cue-induced craving and disadvantageous decision making to be relevant mechanisms. This study investigates if the presentation of social-networks-related cues interferes with decision making under ambiguity.
Methods
Craving was induced with a cue-reactivity paradigm and assessed with a visual analogue scale. Participants (N = 146) played a modified Iowa Gambling Task with social-networks-related cues and neutral cues presented on the advantageous and disadvantageous decks respectively, or vice versa. Symptoms of social-networks-use disorder were measured with a modified version of the short Internet Addiction Test.
Results
Overall, participants chose options with neutral cues more often than those with social-networks-related cues, even if it was disadvantageous. There was a significant interaction between decision-making performance and Iowa Gambling Task condition in predicting symptom severity. The results indicate that choosing decks with social-networks-related cues even if it was disadvantageous is associated with higher tendencies towards a social-networks-use disorder. The interaction with cue-induced craving did not explain further variance.
Discussion and Conclusions
The results highlight the relevance of cue reactivity, decision making, and their interaction as potential mechanisms explaining tendencies towards a social-networks-use disorder. Decision making was influenced by affective responses, which could result in a higher risk of a potential addictive behavior. This is consistent with the findings from addiction research and with theoretical approaches assuming an imbalance between affective and cognitive processes in addictive behaviors.

Abstract
This study aims to analyze thermal stability and make a rheological assessment of sunflower oil produced in the Northeast of Brazil, resulting from the pyrolysis process. Oil samples were submitted to thermal degradation and the reaction was evaluated by the thermogravimetric technique, at temperatures between 30 and 900 °C. Apparent activation energy was determined using the model-free kinetics theory. The coaxial cylinder system at operating temperature of 40 °C was used to obtain rheological parameters. Oil was characterized by gas chromatography. The lipid profile of the oil exhibited good quality. The activation energy of the sunflower oil was 201.2 kJ mol−1. Results showed the influence of physical–chemical characteristics of vegetable oil on the thermal decomposition process. Rheological analyses confirmed Newtonian rheological behavior. The high potential of the “Catissol” variety produced in Northeast Brazil as raw material for biofuel production using pyrolysis was also demonstrated.
Recent research on the reception of interlingual subtitling revealed that it is cognitively effective: watching a subtitled film results in a good understanding of the film content, it does not require a significant tradeoff between image processing and text processing, and it leads to a good performance in the recognition of the words and expressions contained in the subtitles. To date, the studies that revealed the effectiveness of subtitle processing have been conducted mono-nationally — e.g. d’Ydewalle and De Bruycker (2007) in Belgium; Wissmath et al. (2009) in Switzerland; Perego et al. (2010, 2015) in Italy; Hinkin et al. (2014) in the US. However, it has not yet been demonstrated empirically whether subtitle effectiveness varies depending on the familiarity of viewers with subtitles. The cross-national study described in this paper aims to fill this gap and appraise the cognitive performance and overall appreciation of a moderately complex subtitled film by viewers with different degrees of familiarity with subtitles, i.e., viewers living in countries (Italy, Spain, Poland and Dutch-speaking Belgium) with different audiovisual translation traditions. The main findings reveal that subtitling is effective irrespective of users’ familiarity with it, although it is not enjoyed equally among the tested populations.
Abstract
Background and aims
With the inclusion of gaming disorder in the ICD-11, diagnostic criteria were introduced for this relatively new disorder. These criteria may also be applied to other potential specific Internet-use disorders, which may be classified in ICD-11 as other disorders due to addictive behaviors, such as online buying-shopping disorder, online pornography-use disorder, social-networks-use disorder, and online gambling disorder. Due to the heterogeneity in existing instruments, we aimed to develop a consistent and economic measure of major types of (potential) specific Internet-use disorders based on ICD-11 criteria for gaming disorder.
Methods
The new 11-item Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) measures five behavioral addictions with the same set of items by following the principles of WHO’s ASSIST. The ACSID-11 was administered to active Internet users (N = 985) together with an adaptation of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and screeners for mental health. We used Confirmatory Factor Analyses to analyze the factor structure of ACSID-11.
Results
The assumed four-factorial structure was confirmed and was superior to the unidimensional solution. This applied to gaming disorder and to the other specific Internet-use disorders. ACSID-11 scores correlated with IGDT-10 as well as with the measures of psychological distress.
Discussion and Conclusions
The ACSID-11 seems to be suitable for the consistent assessment of (potential) specific Internet-use disorders based on ICD-11 diagnostic criteria for gaming disorder. The ACSID-11 may be a useful and economic instrument for studying various behavioral addictions with the same items and improving comparability.
Abstract
Very high specific activity (AS) 186gRe could be produced by either proton or deuteron cyclotron irradiation on highly enriched 186W target in no-carrier-added (NCA) form, leading to a AS very close to the theoretical carrier free (CF) value of 6.88 GBq μg−1. Thick Target Yields (TTYs), obtained irradiating both thick metal W targets of natural isotopic composition and highly enriched powdered 186W targets, were measured at different particles energies taking into account high accuracy and precision. The evaluation of radionuclidic purities of 186gRe obtained activating highly enriched 186W by both p and d were also carried out and accurately compared. The thin-target excitation functions for all Re (A = 181, 182, 183, 184, 186 and their metastable levels), and W and Ta coproduced radionuclides will be presented elsewhere in deep details.
A retrospective study was conducted to investigate the presence of ferlavirus, ball python nidovirus and bacteria in 32 tracheobronchial lavages from ball pythons raised in captivity and affected by respiratory disease. A touchdown reverse transcription polymerase reaction (RT-PCR) was performed to detect ball python nidovirus RNA targeting a 260-bp portion of the ORF1a gene, while a nested RT-PCR was applied to identify RNA targeting the 518-bp ferlavirus partial L gene. RT-PCR positive products were submitted for Sanger’s sequencing and phylogeny reconstruction. Bacteriological examinations were performed to diagnose a possible bacterial involvement. BLAST analysis revealed that the nucleotide sequences of the six (18.8%) RT-PCR positive amplicons were 90–97% identical to the partial sequence of the ORF1a gene of the recently described ball python nidovirus. All tested snakes were negative for ferlavirus. Thirteen out of 32 samples (40.6%) were bacteriologically positive. Respiratory tract diseases can be a substantial problem for snake breeders, considering the rapid transmission of respiratory pathogens. The results and published studies show that ball python nidovirus is circulating in python collections and could be linked to suboptimal management practices. Surveillance programs are desirable as part of the routine snake health assessment. Tracheobronchial lavage is a fast, practical, cost-effective procedure for sample collection.

Abstract
Background and aims
An increasing number of people experience negative consequences from the excessive use of different Internet applications or sites (e.g., Instagram, League of Legends, YouTube). These consequences have been referred to as specific Internet Use Disorders (IUDs). The present study aims to examine the Fear of Missing Out (FoMO) on rewarding experiences with respect to specific Internet activities. FoMO has been found to mediate the link between psychopathology and symptoms of Internet Communication Disorder (ICD). However, the role of FoMO in other IUDs is controversial.
Methods
The current study (N = 7,990) consecutively screened in vocational schools) analyzed the associations between online-specific state-FoMO, general trait-FoMO, mental health, and IUD symptoms in a structural equation model. After testing the model for the entire sample of Internet users, it was analyzed separately for the two main user groups: Social Networking Site (SNS) users and gamers.
Results
The proposed model explained 42.0% of the variance in IUD symptoms in the total sample, 46.8% for SNS users, and 32.8% for gamers. Results suggest that impaired mental health and high trait-FoMO predict IUD symptoms. For both SNS users and gamers, trait-FoMO mediated the link between low mental health and IUD, whereas state-FoMO mediated the link between trait-FoMO and IUD in both user groups.
Discussion
Our results partly support the theoretical model of specific IUDs, highlighting trait-FoMO as a predisposing fear of disconnection related to general mental health. Online-specific FoMO appears to contribute to problematic Internet use mainly because of its link to the general fear of disconnection. Moreover, the described mechanism seems to be comparable for both females and males.
Conclusions
FoMO is a multidimensional construct underlying IUD symptoms related to the use of socially gratifying, but distinct Internet applications. FoMO and psychopathology should be targeted together in prevention and treatment plans of IUDs.
