Despite this, the relationship between anxiety and driving performance has received very little empirical attention. The Driving Behaviour Scale (Clapp, Olsen, Beck, et al., 2011, Clapp, Olsen, Danoff-Burg, et al., 2011) was developed as a measure of anxious driving behaviours to support research in this area. The current study details adaptation and validation of the Driving Behaviour Scale (DBS; Clapp, Olsen, Beck, et al., 2011, Clapp, Olsen, Danoff-Burg, et al., 2011) in 310 university students in Poland. The overall internal consistency for the DBS was 0.76, while the two subscales demonstrated acceptable internal consistency (safety/cautious = 0.75 and hostile/aggressive behaviours = 0.85). The reliability estimates for performance deficit returned a lower coefficient of 0.65. Factor analysis produced a three-factor solution that supported the original structure of the DBS. The DBS may be utilised as a measure of driving anxiety in samples drawn from the general population.Peer reviewe

Loneliness, Friendship, and Facebook Intrusion. A Study in Poland, Slovakia, Syria, Malaysia, and Ecuador

With the increasing popularity of Facebook, a new social phenomenon connected with its extensive use has appeared: namely, Facebook intrusion. The main aim of the study was to examine the mediating role of loneliness in the relation between friendships and Facebook intrusion. We analyzed data from five countries: Poland (N = 399), Slovakia (N = 266), Syria (N = 475), Ecuador (N = 327), and Malaysia (N = 241). The total sample consisted of 1731 participants who had Facebook accounts; 61% of the participants were women. We administered the Facebook Intrusion Scale, the Loneliness Scale, and the Friendship Scale. The results indicated differences in the role of loneliness and friendship in Facebook intrusion, depending on the country. Among young Polish people, friendship decreases loneliness and loneliness decreases Facebook intrusion. Whereas among Ecuadorians friendship decreases loneliness, while loneliness increases Facebook intrusion

Measurement invariance of the phubbing scale across 20 countries

Mobile phone addiction is a robust phenomenon observed throughout the world. The social aspect of mobile phone use is crucial; therefore, phubbing is a part of the mobile phone addiction phenomenon. Phubbing is defined as ignoring an interlocutor by glancing at one's mobile phone during a face-to-face conversation. The main aim of this study was to investigate how the Phubbing Scale (containing 10 items) might vary across countries, and between genders. Data were collected in 20 countries: Belarus, Brazil, China, Croatia, Ecuador, India, Israel, Italy, Netherlands, Pakistan, Poland, Portugal, Serbia, Slovakia, Slovenia, Spain, Turkey, UK, Ukraine and USA. The mean age across the sample (N = 7696, 65.8% women, 34.2% men) was 25.32 years (SD = 9.50). The cross-cultural invariance of the scale was investigated using multigroup confirmatory factor analyses (MGCFA) as well as the invariance analyses. Additionally, data from each country were assessed individually via confirmatory factor analyses (CFAs). We obtained two factors, based on only eight of the items: (a) communication disturbances and (b) phone obsession. The 8 items Phubbing Scale

PD-L1 Overexpression, SWI/SNF Complex Deregulation, and Profound Transcriptomic Changes Characterize Cancer-Dependent Exhaustion of Persistently Activated CD4+ T Cells

Growing tumors avoid recognition and destruction by the immune system. During continuous stimulation of tumor-infiltrating lymphocytes (TILs) by tumors, TILs become functionally exhausted; thus, they become unable to kill tumor cells and to produce certain cytokines and lose their ability to proliferate. This collectively results in the immune escape of cancer cells. Here, we show that breast cancer cells expressing PD-L1 can accelerate exhaustion of persistently activated human effector CD4+ T cells, manifesting in high PD-1 and PD-L1 expression level son T cell surfaces, decreased glucose metabolism genes, strong downregulation of SWI/SNF chromatin remodelingcomplex subunits, and p21 cell cycle inhibitor upregulation. This results in inhibition of T cell proliferation and reduction of T cell numbers. The RNAseq analysis on exhausted CD4+ T cells indicated strong overexpression of IDO1 and genes encoding pro-inflammatory cytokines and chemokines. Some interleukins were also detected in media from CD4+ T cells co-cultured with cancer cells. The PD-L1 overexpression was also observed in CD4+ T cells after co-cultivation with other cell lines overexpressing PD-L1, which suggested the existence of a general mechanism of CD4+ T cell exhaustion induced by cancer cells. The ChIP analysis on the PD-L1 promoter region indicated that the BRM recruitment in control CD4+ T cells was replaced by BRG1 and EZH2 in CD4+ T cells strongly exhausted by cancer cells. These findings suggest that epi-drugs such as EZH2 inhibitors may be used as immunomodulators in cancer treatment

A global look at time: a 24-country study of the equivalence of the Zimbardo Time Perspective Inventory

In this article, we assess the structural equivalence of the Zimbardo Time Perspective Inventory (ZTPI) across 26 samples from 24 countries (N = 12,200). The ZTPI is proven to be a valid and reliable index of individual differences in time perspective across five temporal categories: Past Negative, Past Positive, Present Fatalistic, Present Hedonistic, and Future. We obtained evidence for invariance of 36 items (out of 56) and also the five-factor structure of ZTPI across 23 countries. The short ZTPI scales are reliable for country-level analysis, whereas we recommend the use of the full scales for individual-level analysis. The short version of ZTPI will further promote integration of research in the time perspective domain in relation to many different psycho-social processes

Factors influencing intentions to text while driving among Polish drivers

Previous research has found that using a mobile phone while driving has a detrimental effect on driver safety and performance. The present study used the Theory of Planned Behaviour (TPB) to examine a number of factors thought to be related to intentions to send or read text messages while driving. A total of 298 Polish drivers completed a survey that included measures of the TPB components related to intentions to send or read text messages in four different scenarios. The scenarios differed according to whether or not the drivers were waiting at traffic lights or travelling at 100 km/h and according to whether or not they were under time pressure. The research found that Attitudes and Perceived Behavioural Control were positive predictors of general intentions to use a mobile phone while driving. Similarly, Attitudes consistently predicted intentions to send and read text messages across the four scenarios. The findings of this study could be utilised for developing an educational campaign aimed at promoting more positive attitudes toward road safety and at reducing intentions to use mobile phones while driving

The role of beliefs in the use of hands-free and handheld mobile phones while driving

Objective: This study investigated the frequency of mobile phones use while driving by mode (handheld vs. hands-free users) and its relationship with three types of beliefs (behavioural, normative and control)

Predictors and consequences of “Phubbing” among adolescents and youth in India: An impact evaluation study

BACKGROUND: “Phubbing” phenomenon, in the frequent use of a smartphone, describes the habit of snubbing someone in favor of a mobile phone. Its predictors and consequences are few in developed countries, but the literature lacks information on its actual occurrence and impact on adolescents and youth in a developing country such as India. MATERIALS AND METHODS: This impact evaluation study was carried out as part of the Phubbing Project of the University of Poland for 6 months (November 15, 2016”May 15, 2017) on a sample of 400 adolescents and youth selected randomly from the five colleges in the district of Muzaffarnagar of Uttar Pradesh state in India. Data were collected through the Internet using e-questionnaires sent to all students. The phubbing predictors' and consequences' scales available in literature were used and data were analyzed by a mixed method to get the study findings. RESULTS: The prevalence of phubbing was 49.3%. The most important predictors associated with phubbers were Internet addiction (p < 0.0001, Odds Ratio 2.26), smartphone addiction (OR 25.9), fear of missing out (OR 18.8), and the lack of self-control (p < 0.0001, OR = 0.73”1.72) . Phubbing also had significant consequences on their social health, relationship health, and self-flourishing, and was significantly related to depression and distress. Logistic regression analysis showed significant impact of phubbing predictors on phubbing consequences in phubbers, especially in depressed and distress status. CONCLUSION: Adolescents and youth of India need special guidance from government adolescent clinics or colleges or even families to control this habit in order to promote better physical, mental, and social health

Sphingolipids as a new factor in the pathomechanism of preeclampsia - Mass spectrometry analysis.

OBJECTIVE(S) AND DESIGN:The aim of the study was to analyse a panel of 11 sphingolipids in plasma and three blood fractions (platelet-poor plasma, platelets and red blood cells) of women with mild preeclampsia. MATERIALS AND METHODS:We recruited 21 women between 25-40 weeks gestation with diagnosed mild preeclampsia to the study group and 36 healthy women with uncomplicated pregnancies, who corresponded with the study group according to gestational age, to the control group. To assess the concentration of 11 sphingolipids in the blood plasma and blood fractions, we used ultra-high performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC/MS/MS). RESULTS:We showed a significant increase in the concentration of eight sphingolipids in the plasma of women with preeclampsia in comparison to the control group: Sph (p = 0.0032), S1P (p = 0.0289), C20-Cer (p < 0.0001), C18-Cer (p < 0.0001), C16-Cer (p = 0.012), C18:1-Cer (p = 0.003), C22-Cer (p = 0.0071), and C24:1-Cer (p = 0.0085). CONCLUSION:We showed that selected sphingolipids, especially C20-Cer and C18-Cer, are totally new factors in the pathomechanism of PE and that these bioactive lipids may play an important role in apoptosis and autophagy
