Previous research has provided strong evidence for a pronounced role of time perspective (TP) in various areas of human functioning, including cognitive processes, mental and physical health, ...environmental behaviors, and relationship quality. The aim of the present study was to investigate the role of individual differences in TP in work-related attitudes and behaviors. In a sample of 200 office workers, we administered a set of questionnaires measuring TPs, job satisfaction, work engagement, Organizational Citizenship Behavior (OCB) and Counterproductive Work Behavior (CWB). Additionally, we controlled for the Big Five personality traits which may be related to the work-related outcomes of interest. Analyses of the data revealed that Future-Positive TP predicted more desired work-related outcomes, i.e., higher job satisfaction, work engagement, and OCB, and lower CWB. An opposite pattern of associations was observed for Present-Fatalistic, Deviation from Balanced Time Perspective, and (partially) for Future-Negative TPs. The vast majority of these effects were still significant after controlling for personality traits. Using path modelling we also demonstrated that the effects of TPs on work behaviors (OCB and CWB) are mostly mediated by job satisfaction and engagement. The present results suggest that TP theory may prove to be a useful tool in organizational psychology for understanding individual differences in work behaviors.
The occurrence of MYC-negative Burkitt lymphoma (BL) has been discussed for many years. The real frequency of the MYC insertion in MYC-negative BL is still unknown. Fine-needle aspiration biopsies of ...108 consecutive patients with clinicopathologically suspected BL (suspBL) were evaluated by flow cytometry, classical cytogenetics, and fluorescence in situ hybridization (FISH). We found 12 cases (11%) without the MYC rearrangement by FISH with a MYC breakapart probe: two patients (1.9%) with cryptic MYC/IGH fusion (finally diagnosed as BL) and 10 patients (9.3%) with 11q gain/loss (finally diagnosed as Burkitt-like lymphoma with 11q aberration). The exact breakpoints of the cryptic MYC/IGH were investigated by next-generation sequencing. The MYC insertions' breakpoints were identified in PVT1 in the first case, and 42 kb upstream of 5'MYC in the second case. To date, a molecular characterization of the MYC insertion in BL has only been reported in one case. Detailed descriptions of our MYC insertions in a routinely and consecutively diagnosed suspBL cohort will contribute to resolving the issue of MYC negativity in BL. In our opinion, the presence of the MYC insertions in BL and other lymphomas might be underestimated, because routine genetic diagnostics are usually based on FISH only, without karyotyping.

Abstract
Background
Richter transformation (RT) is the development of aggressive lymphoma in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). This rare disease is ...characterised by dismal prognosis. In recent years, there has been a deeper understanding of RT molecular pathogenesis, and disruptions of apoptosis (
TP53
) and proliferation (
CDKN2A, MYC, NOTCH1
) has been described as typical aberrations in RT.
Results
A single-institution cohort of 33 RT patients were investigated by karyotyping, fluorescence in situ hybridization and single nucleotide polymorphism/copy number (CN) arrays. Most of RTs were typically manifested by diffuse large B-cell lymphoma, not otherwise specified, among the remaining cases one was classified as high-grade B-cell lymphoma with 11q aberrations. The most frequent alterations (40–60% of cases) were represented by
MYC
rearrangement/gain, deletions of
TP53
and
CDKN2A
,
IGH
rearrangement and 13q14 deletion. Several other frequent lesions included losses of 14q24.1-q32.33, 7q31.33-q36.3, and gain of 5q35.2. Analysis of 13 CLL/SLL-RT pairs showed that RT arised from the CLL/SLL by acquiring of 10 ~ 12 cytogenetic or CN lesions/case, but without acquisition of loss of heterozygosity regions. Our result affirmed the higher genetic complexity in RT than CLL/SLL and confirmed the linear features of RT clonal evolution as predominant.
Conclusions
Cytogenomic profile was concordant with the literature data, however the role of
IGH
rearrangement, 14q deletion and 5q35.2 gain need to be explored. We anticipate that further characterization of RT lesions will probably facilitate better understanding of the RT clonal evolution.
Interest in issues surrounding work–life balance has increased in recent years. Some studies stress the consequences of work–life balance, while others put emphasis on the ways in which people manage ...to keep the balance. We decided to combine both points of view. The presented study focuses on personal strategies for combining family and work roles and their consequences for maintaining the work–family balance and satisfaction with work and quality of life. There were 289 participants in the study. The instruments used were Work–Family Linkage Questionnaire, Work–Family Fit Questionnaire, Satisfaction of Life Scale and Job Satisfaction Scale. The procedure of adapting the Work–Family Linkage Questionnaire (WFLQ) into Polish was conducted to enable the use of the tool in Poland for the first time. Good psychometric properties of WFLQ were confirmed. The results showed that the individual strategy for combining family and work roles determines the work–home balance, as well as satisfaction with life and career. For example, the amount of negative spillover from home and from work was correlated positively with role conflict and negatively with satisfaction with life, while the amount of positive spillover correlated positively with facilitation and experienced satisfaction with life.
This study compared the vegetable intake of preschool children from three European countries Italy, Poland, and the United Kingdom (UK) and explored the parent, child, and environmental factors that ...predicted intake in each country. A total of 408 parents of preschoolers (Italy:
N
= 61, Poland:
N
= 124, and UK:
N
= 225; child mean age = 32.2 months,
SD
= 9.47) completed an online survey comprising a set of standardised questionnaires. For all three countries, the questionnaires included measures of children’s vegetable intake (VegFFQ), child eating behaviour (CEBQ-FF), parents’ mealtime goals (FMGs), and sociodemographic questions about family background and environment. In the UK and Italy, additional questionnaires were used to assess child temperament (EAS-T) and parents’ feeding practices (CFPQ). The results showed that the number of child-sized portions of vegetables consumed per day varied significantly across countries; Polish children consumed the most (∼3 portions) and Italian children the least (∼1.5 portions). Between-country differences were seen in parents’ goals for family mealtimes; compared to Italian parents, Polish and UK parents were more motivated to minimise mealtime stress, increase family involvement in meal preparation, and share the same foods with family members. British and Italian parents also adopted different feeding practices; parents in the UK reported more use of healthy modelling behaviours and more use of foods to support their child’s emotion regulation. In terms of child factors, Italian children were reported to be more emotional and more sociable than British children. Analyses of the relationships between the parent, child, and environmental factors and children’s vegetable intake revealed both similarities and differences between countries. Negative predictors of vegetable intake included child food fussiness in the UK and Poland, child temperament (especially, shyness) in Italy, and the use of food as a reward and child emotionality in the UK. Positive predictors included the parental mealtime goal of ‘family involvement’ in the UK. These results highlight differences in the extent to which European preschoolers achieve recommended levels of vegetable intake, and in the factors that influence whether they do. The results suggest a need to develop healthy eating interventions that are adopted to meet the specific needs of the countries in which they are implemented.
Early childhood education and care (ECEC) centers are ideal venues for food education. As smartphones and tablets are becoming increasingly popular in ECEC centers, technology can be used to deliver ...such pedagogical content. Evidence suggests that video games can affect fruit and vegetable (FV) consumption among 9- to 12-year-old children, but studies among preschoolers are scarce.
This paper describes the development of the Mole's Veggie Adventures app and its effectiveness in increasing FV acceptance among Finnish and Polish preschoolers aged 3 to 6 years.
A multiprofessional team created an app to be used in ECEC centers in groups of 3 to 10 children. The app aimed to increase vegetable acceptance, and it was built using elements that support the development of self-regulation and social skills. Altogether, 7 Finnish and 4 Polish ECEC centers participated in the study. Before randomization, parents reported background factors and their children's willingness to taste different FVs. The ECEC professionals in the intervention arm were instructed to use the app at least once a week during the 3- to 4-week intervention period. The main outcomes in this unblinded, cluster-randomized study were FV acceptance and relative FV acceptance. The first was calculated as a sum variable describing the children's willingness to taste 25 different FVs, the second as FV acceptance divided by the number of FVs served. We used analysis of covariance to compare the FV acceptance and relative FV acceptance scores between the intervention and control groups at follow-up.
A total of 221 children were included in the analysis. At follow-up, the intervention group (115/221, 52%) had higher FV acceptance scores (baseline adjusted difference of mean 7.22; 95% CI 1.41-13.03) than the control group (106/221, 48%). The intervention effect was parallel for relative FV acceptance scores (baseline adjusted difference of mean 0.28; 95% CI 0.05-0.52).
The Mole's Veggie Adventures app has the potential to increase FV acceptance among preschoolers and can be a valuable tool in supporting food education in ECEC centers. Furthermore, the app can be feasibly incorporated into preschool routines in countries with different educational environments.

The aim of the present research was to explore the role of individual differences in time perspective (TP) in predicting two relationship quality indicators: general relationship satisfaction and ...sexual satisfaction, in romantic heterosexual couples. A total amount of 100 dyads took part in the study. Our study revealed that relationship satisfaction indices are predicted by partners’ time perspectives; both actor and partner effects proved significant. For instance, past-negative was related to lower general relationship satisfaction, whereas past-positive proved detrimental to sexual satisfaction. Higher relationship (but not sexual) satisfaction was related to a more balanced time perspective. Moreover, we demonstrated that the role of some time perspective dimensions may change with relationship length, e.g., a relationship between future-positive (FP) time perspective and females’ relationship satisfaction proved to change across relationship course from significantly negative to strongly positive. Contrary to our hypotheses, we found no evidence for assortative mating effects for time perspective dimensions. The present results provide evidence for the role of psychological temporality in relationship functioning and suggests potential utility of time perspective theories in practical interventions aimed to improve romantic relationships’ quality.
