In recent years, the global temperature is continuously rising and has the trend of accelerating. The frequent occurrence of extremely high temperatures and heat waves has caused widespread concern from all walks of life. How to fully understand the change law of temperature becomes very important. In view of the temperature change in Xi’an, this paper introduces a new method called visibility graph to establish the temperature network in Xi’an. On this basis, firstly, this paper studies the relationship between temperature fluctuation and network degree. We find that short-term fluctuations do not cause long-term effects. Then, through the study of network degree distribution, it is revealed that the temperature network conforms to the law of power-law distribution. In addition, this paper also completes the community detection of temperature network, and finds that some communities have fewer nodes (between June and August), which means that the correlation between summer temperature and other seasons in Xi’an is low, and it is easy to form extreme weather. To sum up, the research in this paper provides a new theoretical method and research ideas for mining and mastering the variation law of temperature in Xi’an.

While the relation between terrorism and tourism has been an important topic for tourism research, the questions whether terrorism affects tourism immediately and how long after a terrorism event tourism recovers are, as yet, not clearly answered. The aim of this article is to better understand the magnitude and temporal scale of the impact of terrorism on tourism. To this end, a research model differentiating between short-term and long-term effects of terrorism on tourism is developed and analyzed for the destination Israel using data on tourists from Germany. The results show both short-term and long-term impacts with a time lag between the terrorist event and the beginning of tourism decline of 1 or up to 6 months. An economic influence on the development of tourist arrivals was not detected, but seasonality plays an important role in the relationship between terrorism and tourism.

Abstract Decreased post-operative cerebral region oxygenation saturation (crSO2) variability, a surrogate for cerebral autoregulation, correlates with poor neurodevelopmental outcomes in neonates who undergo cardiac surgery. The goal of this study is to investigate the relationship between pre- and post-operative crSO2 variability in neonates requiring neonatal cardiac surgery for congenital heart disease (CHD). The variability of averaged 1-min crSO2 values was calculated for a minimum of 12h before and for the first 48h following cardiac surgery with cardiopulmonary by-pass in neonates between November 2019 and May 2021. The crSO2 variability increased by 9% with each additional postnatal day in the pre-operative monitoring period (p=0.009). There was a 40% decrease in crSO2 variability between the pre-and post-operative monitoring periods (p<0.001). There were no associations between the degree of decrease in crSO2 variability and CHD classification (aortic arch obstruction or single ventricle physiology). The crSO2 variability improves with each additional postnatal day but then decreases by almost half following cardiac surgery in neonates. We did not observe any association between pre-operative crSO2 variability and post-operative ventilator-free days, post-operative ICU days, or mortality.The long-term effects or significance of reduced crSO2 require further exploration.

AbstractA number of studies have found that humor has a positive short-term effect in terms of enhancing creativity, but few have examined its long-term effects, and few have considered different personality traits when exploring this connection. The present study seeks to address this gap by examining the relationship between creativity and dispositions towards ridicule and being laughed at. We conceptualized humor-induced mirth as a positive emotion within the framework of broaden-and-build theory (Fredrickson 1998), with the potential to foster an individual's disposition towards creative behavior. We hypothesized that this potential would depend on different dispositions towards ridicule and being laughed at. Path analysis was then used to explore the impact of gelotophobia, gelotophilia and katagelasticism on creative performance, with creative disposition as a mediating variable. Gelotophobia, the fear of being laughed at, was found to correlate negatively with creative disposition, and may also exert an indirect negative influence on creative performance through its association with creative disposition. Gelotophilia, the joy of being laughed at, on the other hand, appears to have a partially mediated influence on creativity, exhibiting both a direct and an indirect positive relation through its positive association with creative disposition. No significant relation was observed between katagelasticism (the joy of laughing at others) and creativity.

This essay aims to unearth parenthood in the Nigerian culture through the examples of parental figures in the novel Things Fall Apart by Chinua Achebe. This paper will be citing various studies about Nigerian family structure, bonds and relationship it will also be analysing various incidents throughout the course of the novel. The paper will also be discussing the short term and long term effects of parenting on a child. The paper will take a deeper look into the familial relationships in the Igbo society and the parenting style that they usually followed. It will outline the failure of parental figures in certain incidents with reference to the attachment theory. The paper will be analysing the relationship between Unoka and Okonkwo and its long term effect on Okonkwo, the relationship between Ikemefuna and Okonkwo and the relationship between Nwoye and Okonkwo. The paper will be discussing major events in these relationships and will compare it with the ideal style of parenting. To conclude, the paper would finally unearth parenthood in the Nigerian culture through the examples of parental figures.

Previous short term toxicological studies of one to two weeks duration have demonstrated that MDL 19,660 (5-(4-chlorophenyl)-2,4-dihydro-2,4-dimethyl-3Hl, 2,4-triazole-3-thione), an antidepressant drug, causes a dose-related thrombocytopenia in dogs. Platelet counts started to decline after two days of dosing with 30 mg/kg/day and continued to decrease to their lowest levels by 5-7 days. The loss in platelets was primarily of the small discoid subpopulation. In vitro studies have also indicated that MDL 19,660: does not spontaneously aggregate canine platelets and has moderate antiaggregating properties by inhibiting ADP-induced aggregation. The objectives of the present investigation of MDL 19,660 were to evaluate ultrastructurally long term effects on platelet internal architecture and changes in subpopulations of platelets and megakaryocytes.Nine male and nine female beagle dogs were divided equally into three groups and were administered orally 0, 15, or 30 mg/kg/day of MDL 19,660 for three months. Compared to a control platelet range of 353,000- 452,000/μl, a doserelated thrombocytopenia reached a maximum severity of an average of 135,000/μl for the 15 mg/kg/day dogs after two weeks and 81,000/μl for the 30 mg/kg/day dogs after one week.

<p><em>Child abuse by parents is common in households. The impact of violence on children will bring short-term effects and long-term effects that can be attributed to their various emotional, behavioral and social problems in the future; especially in late adolescence that will enter adulthood. Resilience factors increase the likelihood that adolescents who are victims of childhood violence recover from their past experiences</em><em>,</em><em> become more powerful individuals and have a better life. The purpose of this study was to determine the source of resilience in late adolescents who experienced violence from parents in their childhood. This research uses qualitative research methods with in-depth interviews as a method of data collection. The result shows that the three research participants have the aspects of "I Have", "I Am", and "I Can"; a participant has "I Can" aspects as a source of resilience, and one other subject has no source of resilience. The study concluded that parental affection and acceptance of the past experience have role to the three sources of resilience (I Have, I Am, and I Can)</em></p><p><em> </em></p><p><strong><em>Keyword : </em></strong><em>Resilience, adolescence, violence, parents</em></p>

Abstract Interventions using exercise video games, or exergames, have shown short-term cognitive and physical benefits to older adults, though long-term effects are less promising. Enjoyment of exergames may promote exergame use after the intervention period, though little work has examined older adults’ views of exergames before and after gameplay experience. We invited 20 older adults between 65 and 84 years of age (M=73.30, SD=5.95) to play two Xbox Kinect games, Just Dance and Kinect Sports Rivals, for twenty minutes. In our presentation, we will present qualitative and quantitative findings of this pilot study, including findings that older adults reported that they were not likely to play similar exergames in the future and that they did not find the exergames to be more fun compared to other ways of exercising. We will discuss implications for game design and research relevant to game developers, manufacturers, and researchers. Part of a symposium sponsored by Technology and Aging Interest Group.

Background: Patients with brachial plexus avulsion (BPA) usually experience phantom sensations and phantom limb pain (PLP) in the deafferented limb. It has been suggested that evoking the sensation of touch in the deafferented limb by stimulating referred sensation areas (RSAs) on the cheek or shoulder might alleviate PLP. However, feasible rehabilitation techniques using this approach have not been reported. Objective: The present study sought to examine the analgesic effects of simple electrical stimulation of RSAs in BPA patients with PLP. Methods: Study 1: Electrical stimulation of RSAs for 60 minutes was conducted for six BPA patients suffering from PLP to examine short-term analgesic effects. Study 2: A single case design experiment was conducted with two BPA patients to investigate whether electrical stimulation of RSAs was more effective for alleviating PLP than control electrical stimulation (electrical stimulation of sites on side opposite to the RSAs), and to elucidate the long-term effects of electrical stimulation of RSAs. Results: Study 1: Electrical stimulation of RSAs evoked phantom touch sensations in the deafferented limb, and significantly alleviated PLP (p <  0.05). Study 2: PLP was alleviated more after electrical stimulation on RSAs compared with control electrical stimulation (p <  0.05). However, the analgesic effects of electrical stimulation on RSAs were observed only in the short term, not in the long term (p >  0.05). Conclusions: Electrical stimulation of RSAs not only evoked phantom touch sensation but also alleviated PLP in the short term. The results indicate that electrical stimulation of RSAs may provide a useful practical rehabilitation technique for PLP. Future studies will be required to clarify the mechanisms underlying immediate PLP alleviation via electrical stimulation of RSAs.
