Background: The COVID-19 pandemic has placed considerable pressure on families, testing the quality of relationships and the strength of social support within and beyond the family network. However, little is known about the pre-pandemic factors that predict family relational resilience and social functioning during times of natural disaster or global crisis. Here we use data from one of Australia's longest running studies of social and emotional development to examine the nature and timing of possible relational and social support intervention aimed at preparing families for future adversities. Methods: Data were from the Australian Temperament Project Generation 3 (ATPG3) Study, a population representative three generation cohort study of families established in 1983. A subset of Generation 2 parents completed a COVID-19 specific survey in May-September 2020 (502 parents of 871 children; 60% mothers; 37–38 years). These participants had completed the Quality of Relationships Inventory to assess social support during young adulthood, at 23–24 years (2006) and 27–28 years (2010), before next generation conception. Participants had also completed the Maternity Social Support Scale 1 year postpartum for each child born across the ATPG3 assessment period (2012–2019). In 2020, during the height of the Australian lockdowns, participants rated the quality of their relationships with their partners, children and broader family and friends, in addition to social support within and extended beyond their family. Results: Pre-pandemic partner support was associated with partner relationship quality during the pandemic (β = 0.22). Pre-pandemic support from friends was associated with relationship quality with other family and friends during the pandemic (β = 0.12 – 0.18). Pre-pandemic support (from partner, family and friends) was consistently associated with social support within families during the pandemic (β = 0.11 – 0.21). Pre-pandemic support from friends was also associated with family support extended to others within their local community during the pandemic (β = 0.12 – 0.13). Conclusions: Strengthening supportive relationships during major life transitions, prior to the start of family life and in early parenthood, may have long-term and intergenerational benefits years into the future for both families and communities. This may promote resilience during future crises and other more normative stressful life events.

In a kinematically complete setting, the $K^+ \to \pi^+ \pi^0 \pi^0$ decays of stopped $K^+$ were measured. In the frame work of the Weinberg polynomial expansion, the coefficients up to quadratic terms were deduced. The results are in good agreement with previous measurements and consistent with CP conservation expectations. The empirical $\Delta I=1/2$ rule is violated.

The rare kaon decay K+→π+νν̄ was observed in a data set with comparable sensitivity. The observable signature for K+→π+νν̄ decay from kaons involved the π+ track and π+ decay products. The maximum pion momentum from K+→π+νν̄ decay at rest was found to be 227 MeV/c.

The form factors of the decay K+ --> pi0 e+ nu (K_e3) have been determined from the comparison of the experimental and Monte Carlo Dalitz distributions containing about 10^5 K_e3 events. The following values of the parameters were obtained: lambda_+ = 0.0278 +- 0.0017(stat) +- 0.0015(syst), f_S/f_+(0) = 0.0040 +- 0.0160(stat) +- 0.0067(syst) and f_T/f_+(0) = 0.019 +- 0.080(stat) +- 0.038(syst). Both scalar f_S and tensor f_T form factors are consistent with the Standard Model predictions of zero values., 10 pages, 5 figures, contributed to the proceedings of NANP Conference, Dubna, June 19-23, 2001

An experiment searching for a T-violating transverse muon polarization (Pr) in K+ --> pi (0)mu (+)nu decay is underway at the 12-GeV proton synchrotron at KEK (KEK-PS). This search is sensitive to new mechanisms of T or CP violation beyond the Standard Model. The expected sensitivity from 1996-98 data is presented based on the published result from 1996-97 data and the new result from 1998 data.

An experiment E246 at the 12-GeV proton synchrotron at KEK (KEK-PS), which is searching for the T-violating transverse muon polarization (P-mu(perpendicular to)) in K+ --> pi (0)mu (+)nu decay, is described. The search is sensitive to new mechanisms of T or CP violation beyond the Standard Model. The initial results of P-mu(perpendicular to) = -0.0042+/-0.0049(stat.)+/-0.0009(syst.) and the T-violating parameter Im(xi) = -0.013+/- 0.016(stat.) +/- 0.003(syst.) were determined from the data taken in 1996 and 1997.

A measurement of the transverse mu (+) polarization, P-T, in K+ --> pi (0)mu (+)nu decay was performed using stopped kaons. For 1996-1997 data the results are P-T = -0.0042 +/- 0.0049(stat) +/- 0.0009(syst) and Im(xi) = -0.013 +/- 0.016(stat)+/- 0.003(syst), where Im(xi) is T-violating physics parameter.
