Background: Long-distance travel is common for professional athletes; thus, the impact of jet-lag on athletic performance is a relevant topic. Additionally, older individuals take longer to recover from exercise and post-travel fatigue; therefore, it is likely that age and travel affect performance. Objective: The purpose of this study is to investigate the effects of age and travel on NFL quarterback performance. Method: A correlational research design is used to examine the effects of age and travel on NFL quarterback performance. Data were collected from pro-football-reference.com. Quarterback ratings from the 2018 NFL season are analyzed with age, distance traveled, season week, and weeks since the team’s bye week. The interaction of age and distance is also included to examine the impact of the age-distance relationship on performance. Regression analysis is used to predict quarterback ratings. Results: Season week (p = 0.04), weeks since a bye week (p = 0.041), and distance traveled (p = 0.031) have negative effects on quarterback ratings. The age-performance relationship in NFL quarterbacks is non-linear (p = 0.018), with quarterback performance decreasing during an athlete’s 20s and then increasing during an athlete’s 30s. Additionally, ratings of younger quarterbacks decrease with farther distances traveled, while the ratings of older quarterbacks increase with farther distances traveled (p = 0.072). Conclusions: Differences in performance by age with travel may be the result of different severities of jet-lag symptoms experienced by younger and older quarterbacks, as well differences in strategies for managing post-travel fatigue by athletes of different ages.

The aim of this study is to analyze a new social phenomenon that appeared during the SARS-CoV-2 pandemic, i.e. zoom fatigue. Zoom fatigue is the result of fatigue from long-term conferences, which can also be related to long-term school lessons during distance learning. The main considerations will focus on teenagers, namely on the impact of zoom fatigue on teenagers in Polish schools and on observation of students from technical secondary schools by a school psychologist. This paper, based on the results of research conducted at Stanford University and by Social Changes, is also an attempt to answer the questions: what risks may arise from the phenomenon of zoom fatigue and the threat posed by distance learning for teenagers in the era of Covid-19. It will also attempt to answer the question of how to help students cope with the fatigue of long distance school activities and find ways to help teens deal with isolation and the negative effects of zoom fatigue and find ways to overcome zoom fatigue.

Fertility behaviour is closely related to other dimensions of the individual life course, which are strongly interrelated themselves. Regarding the impact of job-related spatial mobility, empirical findings show a negative correlation between having children and commuting, particularly for women. Up to now, fertility intentions have not been thoroughly investigated in this respect. Longitudinal studies are lacking, too. In this paper, the effects of commuting arrangements of men and women on the intention of having a child within the next two years as well as the probability of realising this intention are addressed. The assumption is, that after accounting for other important factors (employment status, level of qualification, type of consensual union, number of children, residential mobility), medium- and long-distance commuting is negatively related to the fertility intention of women and its realisation. For men, effects are assumed to be nonexistent or even slightly positive. Longitudinal data from the first three waves of the German “Panel Analysis of Intimate Relationships and Family Dynamics” (pairfam) are used to test the hypotheses.Firstly, a cross-sectional, multivariate probit-regression (with correlated errors) on the intention to have a child within two years, on being childless and on medium- and long- distance commuting is applied. The model shows no significant correlation between commuting and the intention to have a child; it does however show a correlation between medium- and long distance commuting and the probability of women to be childless. Secondly, a longitudinal difference model on changing fertility intentions between panel wave 1 and wave 3 is estimated. For women, a positive effect can be found of interrupting medium- and long-distance commuting or, surprisingly, continuing medium- and long-distance commuting on the intention to have a child within two years. Thirdly, for men and women who reported a fertility intention in the first wave, a longitudinal Heckman-selection probit-regression on the probability of having a child between wave 1 and wave 3 is estimated. It shows negative effects of medium- and long-distance commuting on having a child. Taken together, these findings support the assumption that commuting plays a characteristically different role in different phases of the fertility-related decision process.

This research is aimed to test the correlation  between self disclosure and trust among married people experiencing long distance relationship. This research used quantitative method with correlational research design. Participants in this research were 34 people whose spouses are in other cities or overseas with a chance of meeting is no more than once in a month. Participants were selected using snowball sampling. This research used self disclosure and trust scales to collect data and data were analysed using Rank Spearman test. The result shows that coeficient correlation (r) is 0,656 and the significance value is 0,000 (p>0,05), which means that the hypothesis of this research “there is correlation between self disclosure and trust among adult married people experiencing long distance relationship” is accepted.Abstrak: Penelitian ini bertujuan untuk menguji hubungan self disclosure dengan trust pada pasangan dewasa muda yang menikah dan menjalani hubungan jarak jauh. Penelitian ini menggunakan metode penelitian kuantitatif dengan rancangan penelitian korelasional. Partisipan penelitian ini berjumlah  34 orang  yang memiliki karakteristik berusia dewasa muda yang telah menikah dan sedang menjalani hubungan jarak jauh dengan pasangannya baik luar kota maupun luar negeri dengan intensitas bertemu setidaknya satu kali perbulan. Teknik sampling dalam penelitian ini menggunakan snowball sampling. Penelitian ini menggunakan instrumen skala self disclosure dan skala trust. Analisis data yang digunakan adalah Rank Spearman test. Hasil analisis koefisien korelasi menunjukkan (r) sebesar 0,656 dan nilai signifikasi 0,000 (p>0,05), artinya analisis tersebut menunjukkan bahwa hipotesis “ada hubungan self disclosure dengan trust pada pasangan dewasa muda yang menikah dan menjalani hubungan jarak jauh” diterima.

Abstract Background Symptoms of apathy are common in older persons. Negative effects on physical performance and fall risk are plausible, considering the pathophysiology of apathy. However, literature is scarce. Aim To longitudinally assess the association between apathy and 1) decline of physical performance and 2) the number of falls in older community-dwelling persons. Methods The ‘B-vitamins for the PRevention Of Osteoporotic Fractures’ study (B-PROOF) provided data on 2919 older persons over a period of two years. Apathy was assessed using the Geriatric Depression Scale3. A physical performance score (PPS) was calculated using three performance tests. Falls were registered prospectively. We calculated adjusted odds ratios (ORs), Incidence Rate Ratios (IRRs) their 95% confidence intervals (CI). Effect-modification by age and gender was investigated. We also investigated mediation by baseline PPS for the association between apathy and the number of falls. Results Apathy and decline of PPS were independently associated. After stratification, the effect only remained in men. Age was an effect modifier; higher ORs for decreasing age. Apathy was also independently associated with the number of falls. After stratification, women had higher IRRs than men. Age modified the association in the opposite direction: higher IRRs for increasing age. Baseline PPS was a mediator in the association. Conclusion The impact of apathy on physical performance and fall-incidents varied with age and gender. Potentially, in older individuals with apathy, fall risk is preceded by a decline in physical performance. In clinical practice, identifying apathy in older persons might be useful to target mobility preserving interventions.

Despite of the popularity of interactive movie trailers, rigorous research on one of the most apparent features of these interfaces – the level of user control – has been scarce. This study explored the effects of user control on users’ immersion and enjoyment of the movie trailers, moderated by the content type. We conducted a 2 (high user control versus low user control) × 2 (drama film trailer versus documentary film trailer) mixed-design factorial experiment. The results showed that the level of user control over movie trailer interfaces decreased users’ immersion when the trailer had an element of traditional story structure, such as a drama film trailer. Participants in the high user control condition answered that they were less fascinated with, absorbed in, focused on, mentally involved with, and emotionally affected by the movie trailer than participants in the low user control condition only with the drama movie trailer. The negative effects of user control on the level of immersion for the drama trailer translated into users’ enjoyment. The impact of user control over interfaces on immersion and enjoyment varies depending on the nature of the media content, which suggests a possible trade-off between the level of user control and entertainment outcomes.

The paper examines the impact of oil price shocks on inflation, as well as the impact of the choice of the monetary policy regime on the strength of this influence. We used dynamic models on panel data for the countries of the world for the period from 2000 to 2017. It is shown that mainly the impact of changes in oil prices on inflation is carried out through the channel of exchange rate. The paper demonstrates the influence of the transition to inflation targeting on the nature of the relationship between oil price shocks and inflation. This effect is asymmetrical: during periods of rising oil prices, inflation targeting reduces the effect of the transfer of oil prices, limiting negative effects of shock. During periods of decline in oil prices, this monetary policy regime, in contrast, contributes to a stronger transfer, helping to reduce inflation.

The article examines the impact of various socio-economic and financial indicators on the resilience of Russian regions. For each region, the integral index of resilience is calculated, and its correlation dependence with the selected indicators is revealed. The study confirms the relationship between fiscal resilience and socio-economic resilience of the regions. The analysis of panel data for 75 regions from 2007 to 2016 shows that there are significant differences in the dynamics of indicators in different periods. In particular, the degree of exposure to the negative effects of the crises of 2008—2009 and 2014—2015 in non-resilient regions is higher than in resilient ones.
