Massive Open Online Courses (MOOCs) have become a popular tool for worldwide learners. However, a lack of emotional interaction and support is an important reason for learners to abandon their learning and eventually results in poor learning performance. This study applied an integrative framework of achievement emotions to uncover their holistic influence on students’ learning by analyzing more than 400,000 forum posts from 13 MOOCs. Six machine-learning models were first built to automatically identify achievement emotions, including K-Nearest Neighbor, Logistic Regression, Naïve Bayes, Decision Tree, Random Forest, and Support Vector Machines. Results showed that Random Forest performed the best with a kappa of 0.83 and an ROC_AUC of 0.97. Then, multilevel modeling with the “Stepwise Build-up” strategy was used to quantify the effect of achievement emotions on students’ academic performance. Results showed that different achievement emotions influenced students’ learning differently. These findings allow MOOC platforms and instructors to provide relevant emotional feedback to students automatically or manually, thereby improving their learning in MOOCs.

Destruxin A (DA), a hexa-cyclodepsipeptidic mycotoxin produced by the entomopathogenic fungus Metarhizium anisopliae, exhibits insecticidal activities in a wide range of pests and is known as an innate immunity inhibitor. However, its mechanism of action requires further investigation. In this research, the interactions of DA with the six aminoacyl tRNA synthetases (ARSs) of Bombyx mori, BmAlaRS, BmCysRS, BmMetRS, BmValRS, BmIleRS, and BmGluProRS, were analyzed. The six ARSs were expressed and purified. The BLI (biolayer interferometry) results indicated that DA binds these ARSs with the affinity indices (KD) of 10−4 to 10−5 M. The molecular docking suggested a similar interaction mode of DA with ARSs, whereby DA settled into a pocket through hydrogen bonds with Asn, Arg, His, Lys, and Tyr of ARSs. Furthermore, DA treatments decreased the contents of soluble protein and free amino acids in Bm12 cells, which suggested that DA impedes protein synthesis. Lastly, the ARSs in Bm12 cells were all downregulated by DA stress. This study sheds light on exploring and answering the molecular target of DA against target insects.

This qualitative study evaluated an attachment-based group parenting program that utilises mentalisation-based approach. The Building Early Attachment and Resilience (BEAR) program was designed to promote parent-child attachment across the perinatal period and has pre- and post-natal arms. The post-natal component targets mothers and infants at risk for early disturbances of attachment to, and emotional interaction. This evaluation study aimed to explore mothers’ subjective experiences of the post-natal BEAR program in encouraging mothers’ reflection on their role as a parent. Thirteen mothers were interviewed. Transcripts were analysed using thematic analysis, with five themes emerging. Overall, mothers reported that the intervention promoted reflection about the parenting role, contributed to perceptions of improved mother-infant interactions and increased understanding of their infant’s internal experiences. The results suggest the BEAR program is acceptable and facilitates the development of secure parent-infant attachment.

Introductionlong acting injectable formulations of antipsychotics are a valuable option for patients with schizophrenia, offering continuous medication delivery and stable dosage levels. Aripiprazole once-monthly is the first dopamine partial agonist available in long acting formulation approved in Europe for Schizophrenia with excellent results so far.Aimsto conduct a current review of articles related to the use and efficacy of Aripiprazole once monthly in patients with Schizophrenia.Methodssystematic review of the literature in English using the following keywords: “aripiprazole once-monthly”, “aripiprazole long acting formulation”, “schizophrenia”. PubMed database.ResultsAripiprazole once-monthly (AOM) formulation efficacy has been proven in many studies. The importance of maintaining an oral overlap during 14 days is highlighted in all studies that have been reviewed in order to reach therapeutic level; therefore, it can be used in patients with acute decompensations. Recent studies comparing AOM versus Paliperidone Palmitate once monthly (PP) have shown that patients with AOM had greater clinical improvement and, even though both drugs were well tolerated, when Quality of Life Style Scale was analyzed an important improvement in empathy, sense of purpose, emotional interaction and curiosity in the AOM group was observed.Conclusionslong acting injectable antipsychotics increase long-term adherence treatment and reduce risk of relapse. Because of its unique mechanism of action, Aripiprazole once-monthly improves positive and negative symptoms, giving the patient an opportunity to have a better quality of life.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The strengths of PFRP thin-walled columns are determined according to the modes of buckling which consist of local mode for short columns, global mode for long columns, and interaction mode between local and global modes for intermediate columns. Unlike the local and global buckling, the buckling strength of interaction mode is not theoretically predictable. Refined theoretical approaches which can account for different elastic properties of each plate component consisting of a PFRP thin-walled member are used. Based on both the analytical buckling loads and the experimentally measured buckling loads from literatures, the accuracies of Ylinen’s equation and modified AISC/LRFD column design equation for isotropic steel columns were compared. From the comparison, it was found that the modified AISC/LRFD column design equation is more suitable for the prediction of the buckling loads of PFRP thin-walled members than Ylinen’s equations.

Virtual and mixed reality environments (VMRE) often imply full-body human-computer interaction scenarios. We used a public multimodal mixed reality installation, the Synthetic Oracle, and a between-groups design to study the effects of implicit (e.g., passively walking) or explicit (e.g., pointing) interaction modes on the users' emotional and engagement experiences, and we assessed it using questionnaires. Additionally, real-time arm motion data was used to categorize the user behavior and to provide interaction possibilities for the explicit interaction group. The results show that the online behavior classification corresponded well to the users' interaction mode. In addition, contrary to the explicit interaction, the engagement ratings from implicit users were positively correlated with a valence but were uncorrelated with arousal ratings. Interestingly, arousal levels were correlated with different behaviors displayed by the visitors depending on the interaction mode. Hence, this study confirms that the activity level and behavior of users modulates their experience, and that in turn, the interaction mode modulates their behavior. Thus, these results show the importance of the selected interaction mode when designing users' experiences in VMRE.
