Tuning the GENIE Pion Production Model with MINERvA Data
Faced with unresolved tensions between neutrino interaction measurements at
few-GeV neutrino energies, current experiments are forced to accept large
systematic uncertainties to cover discrepancies between their data and model
predictions. In this paper, the widely used pion production model in GENIE is
compared to four MINERvA charged current pion production measurements using
NUISANCE. Tunings, ie, adjustments of model parameters, to help match GENIE to
MINERvA and older bubble chamber data are presented here. We find that
scattering off nuclear targets as measured in MINERvA is not in good agreement
with scattering off nucleon (hydrogen or deuterium) targets in the bubble
chamber data. An additional ad hoc correction for the low- region, where
collective effects are expected to be large, is also presented. While these
tunings and corrections improve the agreement of GENIE with the data, the
modeling is imperfect. The development of these tunings within the NUISANCE
frameworkallows for straightforward extensions to other neutrino event
generators and models, and allows omitting and including new data sets as they
become available

Sobrepeso entre adolescentes de escolas particulares de Fortaleza, CE, Brasil Sobrepeso entre adolescentes de escuelas privadas de Fortaleza, CE, Brasil Overweight among adolescents from private schools in Fortaleza, CE, Brazil
O objetivo da pesquisa foi identificar casos de excesso de peso em adolescentes de escolas particulares de Fortaleza - Brasil. Foram investigados 794 estudantes entre 12 e 17 anos de idade, de 12 escolas privadas, nos meses de março-junho e agosto-setembro de 2007. A prevalência de sobrepeso e obesidade foi, respectivamente, de 20% e 4%. O sobrepeso foi maior, e duplicado os casos de obesidade, naqueles que mantinham o hábito de assistir tevê durante as refeições (p= 0, 000). Cerca de 28% dos jovens ativos apresentavam excesso de peso (p < 0, 001). No combate à adiposidade juvenil, cabe a enfermagem, principalmente, realizar as ações preventivas, pois atenuam diversas repercussões patológicas, relacionados com o acúmulo de peso corporal.<br>El objetivo de la investigación fue identificar los casos de sobrepeso en adolescentes de escuelas privadas de Fortaleza-Brasil.

La prevalencia de sobrepeso y obsedidad fue de 20% y 4%, respectivamente. La acumulación de peso fue mayor y los casos de obesidad fue dos veces más, en los que tenían la costumbre de asistir a la tele al alimentarse (p= 0, 000). Sobre 28% de los jóvenes que practicaban actividad física regularmente presentaban sobrepeso (p < 0, 001). Para la enfermería luchar contra la obesidad entre adolescentes, son necesarias las acciones preventivas, pues atenuan los diversos efectos patológicos con relación a la acumulación de peso corporal.<br>The purpose of the study was to identify cases of overweight among adolescents in private schools in Fortaleza, Brazil. We investigated 794 students between 12 and 17 years old from 12 private schools, in the months March to June and August-September 2007. The prevalence of overweight and obesity was 20% and 4%, respectively. Among the young people who watch TV while eat, the weight accumulated was higher and the cases of obesity was the double (p = 0, 000). About 28% of people who practiced regular physical activity were overweight (p <0, 001). In the fight against adolescent adiposity, to the nursing is primarily the preventive actions, because attenuate various pathological effects related to the accumulation of body weight
Looking through the Window of Opportunity: The Cultural Cleansing of Workplace Identity
This article emerges from a project that examines the relationship between forms of labour, in the context of managerially directed organisational and cultural change, in a light engineering firm on Tyneside. This material is situated within contemporary and historical accounts of workplace interaction. The paper will address the new emphasis on culture and its manipulation, that is increasingly forming a locus of interest in current literature. Whilst stressing that there is much in these accounts that was common in earlier writing the paper draws out what is distinctive about contemporary concerns.
These issues are developed in the empirical account through an analysis of the manipulation of difference along the axes of gender, age and skill. The findings are located within a wider framework of the shift from post figurative to cofigurative culture. In this view there is a reworking of both the substantive relations between generations and in the form of relationships of age and gender.
The result of this analysis is an account which, whilst stressing the radical change that has taken place nevertheless recognises that even the `cleansed culture' is subject to contradictions stemming from the employment relationship. Further, that within the context of the social reproduction of the workplace, shopfloor experience is chronically implicated in the construction of autonomous cultures. As such the analysis provides a more positive interpretation of resistance to such change than that available in many recent accounts
Tuning the GENIE pion production model with MINERvA data
Faced with unresolved tensions between neutrino interaction measurements at few-GeV neutrino energies, current experiments are forced to accept large systematic uncertainties to cover discrepancies between their data and model predictions. The widely used pion production model in genie is compared to four MINERνA charged current pion production measurements using nuisance. Tunings, i.e., adjustments of model parameters, to help match genie to MINERνA and older bubble chamber data are presented. We find that scattering off nuclear targets as measured in MINERνA is not in good agreement with expectations based upon scattering off nucleon (hydrogen or deuterium) targets in existing bubble chamber data. An additional ad hoc correction for the low-Q2 region, where collective nuclear effects are expected to be large, is presented. While these tunings and corrections improve the agreement of genie with the data, the modeling is imperfect. The development of these tunings within the nuisance framework allows for straightforward extensions to other neutrino event generators and models, and allows omitting and including new datasets as they become available
