THE IMPACT OF SUPPORTIVE ADULTS WHILE TRANSITIONING FROM FOSTER CARE TO INDEPENDENCE AMONG SAN BERNARDINO COUNTY FOSTER YOUTH
This study investigated whether the presence of a supportive adult in the life of a youth transitioning out of foster care impacts the likelihood that the youth experiences homelessness, teenage pregnancy, drug or alcohol addiction, or incarceration in San Bernardino County. Understanding the impact of a supportive adult, or mentor, on youth transitioning from foster care to independence would allow the social workers to more strategically plan for a successful exit from state care. This study will use public data collected from the federally mandated survey for the National Youth in Transition Database (NYTD). Data was analyzed to determine if a correlation exists between having a supportive adult and the four aforementioned negative outcomes. The results showed that the four negative consequences examined occurred less frequently with individuals who identified as having a supportive adult in their lives. However, the differences demonstrated by the data were not statistically significant. Further research needs to examine the effect of mentoring on youth transitioning out of foster care

Maternal anxiety and depression and their associations with mother–child pretend play: a longitudinal observational study
Funder: National Institute for Health Research (NIHR) Biomedical Research Centre based at Imperial College Healthcare NHS Trust and Imperial College LondonFunder: LEGO FoundationAbstract: Background: Parental anxiety and depression have been associated with changes to parent–child interactions. Although play constitutes an important part of parent–child interactions and affords critical developmental opportunities, little is known regarding how parental anxiety and depression are related to parent–child play. This is an important knowledge gap because parents play a crucial role in children’s early play experience. The purpose of the current study was to examine whether levels of maternal anxiety and depression respectively predicted frequencies of pretend play in both mothers and their children, and whether mothers’ engagement in pretend play predicted child behaviour problems two years later. Methods: Pretend play in 60 mother-toddler dyads (Mage of child = 29.67 months, SD = 3.25, 41.7% girls) was assessed during home visits. Maternal anxiety and depression were assessed using self-report questionnaires. Children’s behaviour problems were rated by mothers at baseline and two years later. Hierarchical regression analyses examined concurrent associations between mother–child pretend play and maternal anxiety and depression at baseline, and longitudinal associations between baseline mother pretend play and child behavioural problems two years later. Results: Higher maternal anxiety predicted less pretend play in mothers and children (β = − .23, BCa 95% CI: [− .018, − .001]) and β = − .22, BCa 95% CI [− .014, − .001]). Higher maternal depression predicted less child pretend play (β = − .20, BCa 95% CI [− .012, − .001]). There was evidence (albeit weak) that more mother pretend play at baseline predicted fewer child behaviour problems two years later (β = − .18, BCa 95% CI [− 62.38, 11.69]), when baseline child behaviour problems and maternal anxiety were controlled for. Conclusions: Maternal anxiety and depression are associated with less pretend play during mother–child interaction. Mother’s pretend play might help reduce child behavioural problems risks, suggesting that play might be one mechanism by which maternal mental health influences children’s development
Medium Truck Duty Cycle Data from Real-World Driving Environments: Final Report
Since the early part of the 20th century, the US trucking industry has provided a safe and economical means of moving commodities across the country. At present, nearly 80% of US domestic freight movement involves the use of trucks. The US Department of Energy (DOE) is spearheading a number of research efforts to improve heavy vehicle fuel efficiencies. This includes research in engine technologies (including hybrid and fuel cell technologies), lightweight materials, advanced fuels, and parasitic loss reductions. In addition, DOE is developing advanced tools and models to support heavy vehicle research and is leading the 21st Century Truck Partnership and the SuperTruck development effort. Both of these efforts have the common goal of decreasing the fuel consumption of heavy vehicles. In the case of SuperTruck, a goal of improving the overall freight efficiency of a combination tractor-trailer has been established. This Medium Truck Duty Cycle (MTDC) project is a critical element in DOE s vision for improved heavy vehicle energy efficiency; it is unique in that there is no other existing national database of characteristic duty cycles for medium trucks based on collecting data from Class 6 and 7 vehicles. It involves the collection of real-world data on medium trucks for various situational characteristics (e.g., rural/urban, freeway/arterial, congested/free-flowing, good/bad weather) and looks at the unique nature of medium trucks drive cycles (stop-and-go delivery, power takeoff, idle time, short-radius trips). This research provides a rich source of data that can contribute to the development of new tools for FE and modeling, provide DOE a sound basis upon which to make technology investment decisions, and provide a national archive of real-world-based medium-truck operational data to support energy efficiency research. The MTDC project involved a two-part field operational test (FOT). For the Part-1 FOT, three vehicles each from two vocations (urban transit and dry-box delivery) were instrumented for the collection of one year of operational data. The Part-2 FOT involved the towing and recovery and utility vocations for a second year of data collection. The vehicles that participated in the MTDC project did so through gratis partnerships in return for early access to the results of this study. Partnerships such as these are critical to FOTs in which real-world data is being collected. In Part 1 of the project, Oak Ridge National Laboratory (ORNL) established partnerships with the H.T. Hackney Company (HTH), one of the largest wholesale distributors in the country, distributing products to 21 states; and with Knoxville Area Transit (KAT), the city of Knoxville s transit system, which operates across Knoxville and parts of Knox County. These partnerships and agreements provided ORNL access to three Class-7 day-cab tractors that regularly haul 28 ft pup trailers (HTH) and three Class-7 buses for the collection of duty cycle data. In addition, ORNL collaborated with the Federal Motor Carrier Safety Administration (FMCSA) to determine if there were possible synergies between this duty cycle data collection effort and FMCSA s need to learn more about the operation and duty cycles of medium trucks. FMCSA s primary interest was in collecting safety data relative to the driver, carrier, and vehicle. In Part 2 of the project, ORNL partnered with the Knoxville Utilities Board, which made available three Class-8 trucks. Fountain City Wrecker Service was also a Part 2 partner, providing three Class-6 rollback trucks. In order to collect the duty cycle and safety-related data, ORNL developed a data acquisition system (DAS) that was placed on each test vehicle. Each signal recorded in this FOT was collected by means of one of the instruments incorporated into each DAS. Other signals were obtained directly from the vehicle s J1939 and J1708 data buses. A VBOX II Lite collected information available from a global positioning system (GPS), including speed, acceleration, and spatial location information at a rate of 5 Hz for the Part 1 FOT. For the Part 2 FOT, this information was obtained from DAS-based GPS instrumentation. The Air-Weigh LoadMaxx, a self-weighing system that determines the vehicle s gross weight by means of pressure transducers, was used to collect vehicle payload information for the combination, urban transit, and towing and recovery vehicles. A cellular modem, the Raven X EVDO V4221, facilitated the communication between the eDAQ-lite (the data collection engine of the system) and the user. The modem functioned as a wireless gateway, allowing data retrievals and system checks to be performed remotely. Also, in partnership with FMCSA, two additional safety sensors were installed on the combination vehicles: the MGM e-Stroke brake monitoring system and the Tire SafeGuard tire pressure monitoring system. All of these sensors posted data to the J1939 data bus, enabling the signals to be read withou..
Disc fragmentation rarely forms planetary-mass objects
It is now reasonably clear that disc fragmentation can only operate in the
outer parts of protostellar discs ( au). It is also expected that any
object that forms via disc fragmentation will have an initial mass greater than
that of Jupiter. However, whether or not such a process actually operates, or
can play a significant role in the formation of planetary-mass objects, is
still unclear. We do have a few examples of directly imaged objects that may
have formed in this way, but we have yet to constrain how often disc
fragmentation may actually form such objects. What we want to consider here is
whether or not we can constrain the likely population of planetary-mass objects
formed via disc fragmentation by considering how a population of objects at
large radii () au - if they do exist - would evolve under perturbations
from more distant stellar companions. We find that there is a specific region
of parameter space to which such objects would be scattered and show that the
known exoplanets in that region have properties more consistent with that of
the bulk exoplanet population, than with having been formed via disc
fragmentation at large radii. Along with the scarcity of directly-imaged
objects at large radii, our results provide a similar, but independent,
constraint on the frequency of objects formed via disc fragmentation.Comment: 8 pages, 5 figures, accepted for publication in Monthly Notices of

Prioritizing people and rapid learning in times of crisis: A virtual learning initiative to support health workers during the COVID‐19 pandemic
The Western Cape province was the early epicentre of the
coronavirus disease 2019 pandemic in South Africa and on
the African continent. In this short article we report on an
initiative set up within the provincial Department of Health
early in the pandemic to facilitate collective learning and
support for health workers and managers across the health
system, emphasising the importance of leadership, systems
resilience, nonhierarchical learning and connectedness.
These strategies included regular and systematic engagement with organised labour, different ways of gauging and
responding to staff morale, and daily ‘huddles’ for raid
learning and responsive action
Household Contamination with Salmonella enterica1
Household contamination with Salmonella enterica increases when occupational exposure exists (cattle farms with known salmonellosis in cattle, a salmonella research laboratory, or a veterinary clinic experiencing an outbreak of salmonellosis). Fifteen of 55 (27.2%) vacuum cleaner bags from households with occupational exposure to S. enterica were positive versus 1 of 24 (4.2% without known exposure. Use of a carpet cleaner and several cleaners/disinfectants reduced, but failed to eliminate, S. enterica from artificially contaminated carpet

A video-feedback parenting intervention to prevent enduring behaviour problems in at-risk children aged 12-36 months: the Healthy Start, Happy Start RCT.
BACKGROUND: Behaviour problems emerge early in childhood and place children at risk for later psychopathology. OBJECTIVES: To evaluate the clinical effectiveness and cost-effectiveness of a parenting intervention to prevent enduring behaviour problems in young children. DESIGN: A pragmatic, assessor-blinded, multisite, two-arm, parallel-group randomised controlled trial. SETTING: Health visiting services in six NHS trusts in England. PARTICIPANTS: A total of 300 at-risk children aged 12-36 months and their parents/caregivers. INTERVENTIONS: Families were allocated in a 1 : 1 ratio to six sessions of Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD) plus usual care or usual care alone. MAIN OUTCOME MEASURES: The primary outcome was the Preschool Parental Account of Children's Symptoms, which is a structured interview of behaviour symptoms. Secondary outcomes included caregiver-reported total problems on the Child Behaviour Checklist and the Strengths and Difficulties Questionnaire. The intervention effect was estimated using linear regression. Health and social care service use was recorded using the Child and Adolescent Service Use Schedule and cost-effectiveness was explored using the Preschool Parental Account of Children's Symptoms. RESULTS: In total, 300 families were randomised: 151 to VIPP-SD plus usual care and 149 to usual care alone. Follow-up data were available for 286 (VIPP-SD, n = 140; usual care, n = 146) participants and 282 (VIPP-SD, n = 140; usual care, n = 142) participants at 5 and 24 months, respectively. At the post-treatment (primary outcome) follow-up, a group difference of 2.03 on Preschool Parental Account of Children's Symptoms (95% confidence interval 0.06 to 4.01; p = 0.04) indicated a positive treatment effect on behaviour problems (Cohen's d = 0.20, 95% confidence interval 0.01 to 0.40). The effect was strongest for children's conduct [1.61, 95% confidence interval 0.44 to 2.78; p = 0.007 (d = 0.30, 95% confidence interval 0.08 to 0.51)] versus attention deficit hyperactivity disorder symptoms [0.29, 95% confidence interval -1.06 to 1.65; p = 0.67 (d = 0.05, 95% confidence interval -0.17 to 0.27)]. The Child Behaviour Checklist [3.24, 95% confidence interval -0.06 to 6.54; p = 0.05 (d = 0.15, 95% confidence interval 0.00 to 0.31)] and the Strengths and Difficulties Questionnaire [0.93, 95% confidence interval -0.03 to 1.9; p = 0.06 (d = 0.18, 95% confidence interval -0.01 to 0.36)] demonstrated similar positive treatment effects to those found for the Preschool Parental Account of Children's Symptoms. At 24 months, the group difference on the Preschool Parental Account of Children's Symptoms was 1.73 [95% confidence interval -0.24 to 3.71; p = 0.08 (d = 0.17, 95% confidence interval -0.02 to 0.37)]; the effect remained strongest for conduct [1.07, 95% confidence interval -0.06 to 2.20; p = 0.06 (d = 0.20, 95% confidence interval -0.01 to 0.42)] versus attention deficit hyperactivity disorder symptoms [0.62, 95% confidence interval -0.60 to 1.84; p = 0.32 (d = 0.10, 95% confidence interval -0.10 to 0.30)], with little evidence of an effect on the Child Behaviour Checklist and the Strengths and Difficulties Questionnaire. The primary economic analysis showed better outcomes in the VIPP-SD group at 24 months, but also higher costs than the usual-care group (adjusted mean difference £1450, 95% confidence interval £619 to £2281). No treatment- or trial-related adverse events were reported. The probability of VIPP-SD being cost-effective compared with usual care at the 24-month follow-up increased as willingness to pay for improvements on the Preschool Parental Account of Children's Symptoms increased, with VIPP-SD having the higher probability of being cost-effective at willingness-to-pay values above £800 per 1-point improvement on the Preschool Parental Account of Children's Symptoms. LIMITATIONS: The proportion of participants with graduate-level qualifications was higher than among the general public. CONCLUSIONS: VIPP-SD is effective in reducing behaviour problems in young children when delivered by health visiting teams. Most of the effect of VIPP-SD appears to be retained over 24 months. However, we can be less certain about its value for money. TRIAL REGISTRATION: Current Controlled Trials ISRCTN58327365.

Binomial Mitotic Segregation of MYCN-Carrying Double Minutes in Neuroblastoma Illustrates the Role of Randomness in Oncogene Amplification
BACKGROUND: Amplification of the oncogene MYCN in double minutes (DMs) is a common finding in neuroblastoma (NB). Because DMs lack centromeric sequences it has been unclear how NB cells retain and amplify extrachromosomal MYCN copies during tumour development. PRINCIPAL FINDINGS: We show that MYCN-carrying DMs in NB cells translocate from the nuclear interior to the periphery of the condensing chromatin at transition from interphase to prophase and are preferentially located adjacent to the telomere repeat sequences of the chromosomes throughout cell division. However, DM segregation was not affected by disruption of the telosome nucleoprotein complex and DMs readily migrated from human to murine chromatin in human/mouse cell hybrids, indicating that they do not bind to specific positional elements in human chromosomes. Scoring DM copy-numbers in ana/telophase cells revealed that DM segregation could be closely approximated by a binomial random distribution. Colony-forming assay demonstrated a strong growth-advantage for NB cells with high DM (MYCN) copy-numbers, compared to NB cells with lower copy-numbers. In fact, the overall distribution of DMs in growing NB cell populations could be readily reproduced by a mathematical model assuming binomial segregation at cell division combined with a proliferative advantage for cells with high DM copy-numbers. CONCLUSION: Binomial segregation at cell division explains the high degree of MYCN copy-number variability in NB. Our findings also provide a proof-of-principle for oncogene amplification through creation of genetic diversity by random events followed by Darwinian selection
