Travel constraints positively influence nostalgia. In addition, the relationship between travel constraints and destination attachment and the relationship between travel constraints and revisit intention are fully mediated by nostalgia. Moreover, nostalgia positively affects destination attachment and revisit intention. Also, destination attachment partially mediates the association between nostalgia and revisit intention. Finally, prevention regulatory focus positively moderates the effect of travel constraints on nostalgia.

Early life seizures in rodents leads to autistic-like behavior, characterized by low preference for novelty, deficit in social recognition and high anxiety. We used this animal model to better understand the role of the endocannabinoid system on sociability. Male Wistar rats at postnatal day 9 were subjected to pilocarpine-induced neonatal status epilepticus and controls received saline. From P60 groups received vehicle or JZL195 2 hours prior each behavioral test, in order to increase endocannabinoids availability. In social discrimination test, untreated control animals spent higher time with social novelty as compared to familiar one (t= 3.263; p0.05). In this paradigm, the significant interaction between factors (conspecific x treatment) (F(1,19)= 4.863;p=0.04) suggests that control animals under JZL195 effect exhibited reduced social motivation. In contrast, the untreated experimental group did not show preference for social novelty (t= 0.336; p>0.05) and JZL195 did not modify the impaired social discrimination. In social recognition test, control animals, regardless the treatment, showed habituation to the social stimulus (F(2,32)= 11.64, p=0.0002), suggesting that animals exhibited social recognition memory, but it was reduced by the treatment with JZL 195 (F(1,16)= 5.086, p= 0.038). Moreover, time of investigation increased when the familiar social stimulus was replaced by new one (F(1,16)=10.24, p=0.005), suggesting that social memory recognition was preserved. Treated control animals exhibited a lower time of investigation toward social stimulus (F(1,16)=9.092, p=0.0082), suggesting that JZL195 reduced the social motivation without affect social recognition memory. In the experimental group, the time of investigation decreased when exposed to the same animal (F (2,34)=7.92, p=0.0015), suggestive that the social recognition was preserved and unaffected by the treatment with JZL195 (F(1,17)= 0.246; n.s). The JZL195 decreased the time of investigation only in control group (t=2.464, p= 0.025) to values that are similar to the experimental one. After behavioral tests, brain tissues were used for CB1 receptor quantification by Elisa and for gene expression by RT-PCR: no difference between control and experimental animals was detected. Our results state that increased endocannabinoid signaling reduces social motivation in intact rats and has no effect in animals submitted to early life seizures.
The dataset has developed for the cross-sectional study conducted from January to June 2018 in three randomly selected tertiary hospitals. All the children diagnosed and treated at those hospitals during the study period were eligible for this study. Measures included socio-demographic attributes, financial burden, personal strain, social impact, mastery, and treatment cost. Face-to-face interview was conducted among 242 parents using a semi-structured questionnaire based on (i) About you and your-family and (ii) the Impact-On-Family scale. High scores of the scale correlated to high impact. Informed written consent was obtained from the parents.
Icequakes, micro-seismicity caused by glacier deformation and motion, provide important information to study glacier dynamics and its responses to environmental changes at various temporal and spatial scales. In this study, we apply a multi-dimensional autoregressive maximum-likelihood algorithm to obtain 12 icequake templates on the Urumqi Glacier No. 1, China, and detect 65,363 icequakes through template matching. Centroid location of the 12 templates indicate that most icequakes are caused by surface crevasses inside the glacier, which are characterized by dominant surface waves. The icequakes show seasonal variation with more events in summer because of faster ice flow due to high temperature and precipitation. In winter, however, the icequakes, on par with those in summer, suggest considerable glacier growth in cold weather. Because of higher ice flow velocity due to low tide, the number of icequakes has two daily peaks which seems to negatively correlate with semi-diurnal solid tide.

This dataset refers to the data of 1244 people, aged from 18 to 72 years. Data concerns socio-demographic and epidemiological information and results to 3 questionnaires, as follows.
The authors of the study used the information available on WHO website to examine knowledge about COVID-19. Eight questions were used to examine the participants knowledge about coronavirus, 5 of them were multiple choice questions and 3 questions were true/false type questions. Various types of factor and reliability analyzes were performed to see whether a linear combination of the results could be used, but the results did not support this. It was then decided to consider each question as separate, examining their relationship to the research variables. Participants were divided in two groups for each of the 8 questions according to their answers. More specifically, if a participant scored correctly on question 2, but incorrectly on question 3 he was put in the ‘informed’ group for question 2 and the ‘uninformed’ group for question 3.
The The Hospital Anxiety and Depression scale (HADS) (Zigmond and Snaith, 1983:Pokrajac-Bulian et al. 2015) is divided in the Anxiety subscale and the Depression subscale. Both subscales contain 7 items. Participants were divided into three categories according to the authors.
The Optimism-Pessimism scale (OPS) (Penezić,2000) was to measure positive and negative expectations of future activities outcome. This scale consists of the Optimism subscale which has 6 items and the Pessimism subscale which has 8 items.

The deposition of atmospheric nitrate (NO3−) reflects a balance of anthropogenic and natural nitrogen oxide (NOX) sources. The Tibetan Plateau, one of the most pristine global areas, is highly sensitive to anthropogenic effects, thus is of great importance for evaluating human activity disturbance on natural system. However, the current sources of nitrate deposition on the Tibetan Plateau are still poorly constrained. In this study rainwater from the Gongga Mountain, which is located in the eastern Tibetan Plateau, was collected from Aug. 2014 to Aug. in 2015, and the chemical and nitrogen isotopic compositions were determined. The δ15N composition of nitrate in rainwater was found to be high during the early cool season (November to January: −2.8‰), and low during the late cool season (February to March: −15.3‰), with intermediate values during the warm season (April to October: −5.8‰). In the warm season, trajectory paths and similar intermediate δ15N values imply that sea aerosol from the Indian Ocean as the main source of the precipitation nitrate. In the cool season, variable δ15N values suggest a more complicated and dynamic control on precipitation nitrate in the eastern Tibetan Plateau. In the early cool season, anthropogenic NOX derived from fuel combustion in the Indian sub-continent are inferred to dominate the precipitation NOX in the study site, based on high K+ concentration and nitrogen isotopic value and on the trajectory analyses. The increased intensity of agricultural activity in the Indian sub-continent during the late cool season shifts the δ15N values lower and drives a peak of NH4+ and NO3− concentration of the precipitation. These findings represent the first constraints on the origin of precipitation nitrate in the Tibetan Plateau and demonstrates that the Tibetan Plateau responds quickly to anthropogenic nitrate derived by long−range transport from the Indian sub-continent.
