School Sense of Community, Teacher Support, and Students\u2019 School Safety Perceptions

This study examined the association between two characteristics of school climate (sense of community and teacher support, measured both at the individual and at the school level) and students\u2019 feelings of being unsafe at school. The study involved a sample of 49,638 students aged 10\u201318 years who participated in the 2010\u20132012 California Healthy Kids Survey. Using hierarchical linear modeling (HLM), our findings revealed that, at the individual level, students perceiving higher levels of sense of community and teacher support at school were less likely to feel unsafe within the school environment. At the school level, sense of community was negatively associated with unsafe feelings, whereas there was no association between school-level teacher support and feelings of being unsafe at school

Investigation of the existence of hybrid stars using Nambu-Jona-Lasinio models

We investigate the hadron-quark phase transition inside neutron stars and obtain mass-radius relations for hybrid stars. The equation of state for the quark phase using the standard NJL model is too soft leading to an unstable star and suggesting a modification of the NJL model by introducing a momentum cutoff dependent on the chemical potential. However, even in this approach, the instability remains. In order to remedy the instability we suggest the introduction of a vector coupling in the NJL model, which makes the EoS stiffer, reducing the instability. We conclude that the possible existence of quark matter inside the stars require high densities, leading to very compact stars.Comment: 4 pages, 2 figures; prepared for IV International Workshop on Astronomy and Relativistic Astrophysics (IWARA 2009), Maresias, 4-8 Oct 200

Switch from public to private retail pharmaceutical expenditures: evidence from a time series analysis in Italy

Objectives To analyse trajectories of retail pharmaceutical expenditures from 2010 to 2019 in Italy to investigate whether there was a switch from public to private expenditure, how the composition of private and public expenditure changed, and whether there are correlations with supply/demand variables. Answering these questions is important to assure pharmaceutical care to all citizens in a public health system where expenditure containment is the issue of pharmaceutical policies. Design and setting Time-trend analysis was carried out in the Italian National Health System (NHS), between 2010 and 2019. We considered the following: Public pharmaceutical expenditure with/without direct distribution of drugs, copayments, household out-of-pocket payments for drugs reimbursable/non-reimbursable by the NHS, and for drugs without prescription requirement. Correlations were tested between expenditure items and relevant statistics (Gini coefficient, resident population demographics, ages and categories of physicians, and current expenditure on health). Results The switch feared between public and private pharmaceutical expenditures was not found: Private expenditure increased (average annual per cent change 1.5%; 95% CI 0.3% to 2.6%), but public spending remained stable (-1.0%; 95% CI -3.0% to 1.1%). Single items of expenditure exhibited significant pattern changes over the study period. A switch from public expenditure without direct distribution of drugs (-3.9%) to expenditure with direct distribution was found (+8.4%). Unexpected increases in household out-of-pocket payments for drugs reimbursable by the NHS (+6.1%) and in copayments (+4.9%) were shown. No notable correlations were found. Conclusions This study offers insights into Italian experience that can be applied to other contexts and the results provide policy-makers issues to reflect on. The findings suggest that policies of pharmaceutical-expenditure management may have multiple effects and unexpected combined effects over time that should be considered when they are designed, and suggest that health policies must be adopted with a systematic logic and a broad and unified vision

Microscopic cluster model for the description of new experimental results on the C 13 (O 18, O 16) C 15 two-neutron transfer at 84 MeV incident energy

The C13(O18,O16)C15 reaction is studied at 84 MeV incident energy. Excitation energy spectra and absolute cross-section angular distributions for the strongest transitions are measured with good energy and angular resolutions. Strong selectivity for two-neutron configurations in the states of the residual nucleus is found. The measured cross-section angular distributions are analyzed by exact finite-range coupled reaction channel calculations. The two-particle wave functions are extracted using the extreme cluster and the independent coordinate scheme with shell-model derived coupling strengths. A new approach also is introduced, the microscopic cluster, in which the spectroscopic amplitudes in the center-of-mass reference frame are derived from shell-model calculations using the Moshinsky transformation brackets. This new model is able to describe well the experimental cross section and to highlight cluster configurations in the involved wave functions
