Although prior research has indicated that peer norms for aggression enhance the spread of aggression in classrooms, it is unclear to date how these norms relate to students' classroom climate perceptions and school adjustment. Aggressive descriptive norms reflect the average aggression of all students in classrooms, whereas aggressive popularity norms represent the extent to which aggressive behavior relates to popularity among peers. This study examined the role of aggressive descriptive and popularity norms in the classroom climate perceptions (cooperation, conflict, cohesion, isolation) and school adjustment (feelings of belonging; social, academic, and general self-esteem) of popular, well-liked, and victimized children. Self-reported and peer-nominated data were obtained from 1511 children (Mage = 10.60 years, SD = 0.50; 47.2% girls) from 58 fifth-grade classrooms. The results indicated that aggressive descriptive and popularity norms both matter in elementary school, but in diverging ways. Specifically, aggressive descriptive norms-rather than popularity norms-contributed to negative classroom climate perceptions irrespective of students' social position. In addition, whereas descriptive norms contributed to between-classroom variations in some aspects of school adjustment, aggressive popularity norms related to increased school maladjustment for popular and victimized children specifically. Thus, aggressive descriptive norms and popularity norms matter in complementary ways for children's classroom climate perceptions and adjustment in elementary education.Developing a personal identity is a core developmental task for all adolescents. Immigrant adolescents need to integrate the meaning that their belonging to their ethnic group and the receiving nation has for them into their personal identity. The purpose of this study was to examine the longitudinal interplay between personal, ethnic, and national identities of a middle school sample of immigrant youth (N = 765, Mage = 12.7 years, SD = 0.6 at T1; 46% girls) enroled in Greek schools. Data were collected in three waves with repeated measures. To test the link between these identities, two trivariate Cross-Lagged Panel Models were ran, one examining identity exploration and the other examining identity commitment. The results revealed robust within time positive links between ethnic, national and personal identities for both exploration and commitment at all three time-points. There was some evidence that ethnic and national identities were negatively linked longitudinally, and limited support for longitudinal associations between these domains and personal identity. Follow-up analyses suggest that these processes may be specific to second generation youth and that findings may differ by ethnic background. Finally, the findings that emerged are discussed with attention to the socio-political climate in the receiving nation.
Preoperative digital templating is a standard procedure in total hip arthroplasty. Deviations between template size and final implant size may result from inaccurate calibration, templating as well as intraoperative decisions. So far, the explicit effect of calibration errors on templating has not been addressed adequately.
A mathematical simulation of calibration errors up to ± 24% was applied to the templating of acetabular cups (38 to 72mm diameter). The effect of calibration errors on template component size as deviation from optimal size was calculated.
The relationship between calibration error and component size deviation is inverse and linear. Calibration errors have a more pronounced effect on larger component sizes. Calibration errors of 2-6% result in templating errors of up to two component sizes. Common errors of up to 12% may result in templating errors of 3-4 sizes for common implant sizes. Protein Tyrosine Kinase inhibitor A tabular matrix visualizes the effect.
Calibration errors play a significant role in component size selection during digital templating. Orthopedic surgeons should be aware of this effect and try to identify and address this source of error.

Between 2015 and 2019, 261,091 refugees were resettled through the U.S. Refugee Admissions Program. Few are chronically ill, but previously these went to emergency rooms upon arrival. We designed a pilot program to anticipate, assess, and safely assume care of chronic health needs and stabilize sick and medically complex refugees upon arrival.
Academic internal medicine and pediatrics clinics are linked to the Washington State Refugee Health Program and Refugee Resettlement Agencies. Arriving refugees deemed medically complex through overseas medical evaluation or post-arrival were selected for the program.
We reviewed biodata of 2,947 refugees deemed medically complex. We referred five hundred and sixty one (19%) of these for evaluation, and 257 (46%) of referrals received care.
Safe transitions of care are standard practice in medical systems. This innovation in Seattle is one example of a system for the safe and cost-effective relocation of refugees with complex illnesses.

Hence, this study was designed with the aim to isolate phyto-constituents from C. pruniferus with potent anti-inflammatory activities. Column and volume liquid chromatography were used for isolation of phyto-constituents. The structure elucidation was carried out using spectroscopic analysis (HRESI-MS, 1H and 13C-NMR) and compared with published literature. For cytotoxicity analysis, 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium-bromide assay was performed on peripheral blood mononuclear cells. Anti-inflammatory activities were evaluated against the levels of inflammatory cytokines (IL-1β and IL-6), prostaglandin-E2 (PGE2) and cyclooxegenase-2 (COX-2), in lipopolysaccharide (LPS)-induced human plasma using ELISA and radioimmunoassay (RIA). The chromatographic purification of methanol leaves extract afforded 13 (1-13) secondary metabolites. Additionally, cytotoxicity analysis suggested that isolates were non-cytotoxic at 100 μM.
